EVST builds painting robot solutions across three dedicated lines: long-reach 6-axis painting arms (QJRP6-2700P at 6 kg payload / 2,701 mm reach; QJRP10-1 at 10 kg / 2,035 mm reach), the XR-EX explosion-proof collaborative robot series (XR12-EX at 12 kg / 1,300 mm reach; XR18-EX at 18 kg / 900 mm reach) carrying ATEX Zone 1/2 and IECEx certification for solvent-present paint areas, and the EVST teach-free spray system (TSRC100-7; 9-axis serial control with 12-axis additional linkage) delivered as turnkey cells with overhead conveyors, spray booths, and curing ovens. For broader context on applicator selection and ROI methodology, see our Painting Robot Buying Guide.

EVST Painting Robot Portfolio Overview

According to the International Federation of Robotics (IFR), painting and coating consistently ranks among the top five application categories for industrial robots globally. Within automotive and light-industrial manufacturing, coating quality directly links to product defect rates and rework cost. EVST addresses this with a painting-specific product range that spans the full payload spectrum, from collaborative spray cells for mid-size manufacturers to long-reach industrial arms for automotive body lines.

EVST Long-Reach Painting Arm — Body Panels (QJRP6-2700P)

EVST’s long-reach painting arm (QJRP6-2700P) is the company’s longest-reach painting arm: 6 kg payload, 2,701 mm maximum reach. This model is designed for vehicle body spraying, large panel coating, and door-inner surface applications where a conventional arm cannot access deep recesses without repositioning. The extended reach means a single robot can cover a wider spray envelope, reducing the number of stations required per line.

EVST Mid-Payload Painting Arm — General Coating (QJRP10-1)

EVST’s mid-payload painting arm (QJRP10-1) carries 10 kg payload at a 2,035 mm reach. This is the standard choice for general-purpose painting: auto parts (bumpers, side mirrors, wheel arch liners), sanitary ware, furniture components, and agricultural equipment covers. The additional payload margin compared to the long-reach model accommodates heavier spray gun assemblies and electrostatic atomizer heads.

XR-EX Series — ATEX/IECEx Explosion-Proof Collaborative Robots

The XR-EX series (XR12-EX: 12 kg / 1,300 mm reach / ±0.03 mm repeatability; XR18-EX: 18 kg / 900 mm reach / ±0.02 mm repeatability) carries IP68 ingress protection plus ATEX Zone 1/2 and IECEx dual certification. EVST is the first Chinese manufacturer to deliver a certified explosion-proof collaborative robot, making the XR-EX uniquely suited to solvent-borne paint applications where vapor concentration can reach the lower flammable limit. All cabling, connectors, sensors, and end-effector interfaces on the XR-EX are rated for the classified hazardous zone.

EVST Teach-Free Painting System (TSRC100-7)

The EVST teach-free painting system (TSRC100-7) removes conventional robot programming from the painting workflow. A trained paint technician demonstrates the spray path directly with a handheld gun on the actual workpiece; the system captures the full 9-axis trajectory and reproduces it with ±2–5 mm precision at production speed. The control cabinet (AC220V, operating range -10°C to +75°C) communicates via EtherCAT servo and TCP/IP to the host controller with no additional PLC required. Standard configuration is 9-axis serial control; an additional 12-axis linkage option supports complex multi-robot or gantry configurations.

Painting Cell Architectures

Selecting the right cell layout shapes throughput, footprint, and capital cost more than the robot model itself. EVST supplies four standard painting cell configurations, each suited to a different production profile. All configurations are available as turnkey systems inclusive of spray booth, ventilation, conveyor, and curing oven on request.

Reciprocator Cell (Linear Track + Robot)

A reciprocator-style cell mounts the painting robot on a linear track running parallel to an overhead conveyor. Parts hang from the conveyor and pass through the spray zone at a set speed. This layout is the standard for high-volume automotive body painting and large-panel coating, where continuous throughput is more important than part repositioning. EVST’s long-reach painting arm (QJRP6-2700P) is the natural choice here: its 2,701 mm reach covers the width of a typical sedan door or quarter panel from a single track position.

Stationary 6-Axis Cell (Medium and Small Parts)

For medium to small parts (bumpers, wheel arch liners, sanitary ware fixtures, agricultural equipment covers), a stationary 6-axis painting cell positions the robot at a fixed base with a rotary turntable or single-axis tilt fixture beneath it. The EVST mid-payload painting arm (QJRP10-1) at 10 kg payload handles bell cup electrostatic heads for these applications. Cycle times in this configuration are predictable and program changes are straightforward when running family-of-parts schedules.

Cobot-Assisted Touch-Up Cell with XR-EX (Fenceless)

In paint-shop adjacent zones where a trained paint technician needs to work alongside the robot for quality inspection and touch-up, the XR-EX cobot cell removes the perimeter fence requirement. Because the XR-EX carries full ATEX Zone 1/2 certification, it can operate inside solvent-present areas without a separate flame-proof enclosure for the robot body itself. This configuration is common where a fully automated line is impractical due to high SKU variety or complex surface geometry requiring human judgment at specific areas of the part.

Multi-Station Cell with Curing Oven Integration

For operations running primer plus topcoat sequences, EVST configures multi-station cells with a curing oven between spray zones. A part enters the first spray station (primer), passes through a flash-off zone, enters the curing oven, exits into the topcoat spray station, and then moves to final cure. Overhead conveyor pacing synchronizes robot spray programs to the line speed. EVST provides full integration engineering for oven temperature profiles, conveyor drives, and booth exhaust management as part of the turnkey scope.

ATEX / IECEx Explosion-Proof Configurations

Solvent-borne coatings generate volatile organic compounds (VOCs) that can accumulate to flammable concentrations inside a spray booth. European ATEX Directive 2014/34/EU and the IECEx Scheme define the equipment protection levels required in each zone. Most enclosed spray booths using solvent-borne paints are classified ATEX Zone 1 (explosive atmosphere present occasionally) or Zone 2 (present only in abnormal conditions). Standard industrial robots are not rated for these zones and cannot be used without a separate, certified explosion-proof enclosure.

What the XR-EX Certification Covers

The XR12-EX and XR18-EX carry ATEX Zone 1/2 certification and IECEx dual approval. IP68 protection means the robot body withstands continuous immersion-equivalent conditions — relevant in paint-mist-heavy environments. All cabling, joint seals, connectors, and end-effector mounting flanges on the XR-EX are rated to the same classification. The XR-EX does not require a separate flame-proof enclosure around the robot, which reduces booth footprint and simplifies maintenance access compared to conventional industrial-robot solutions housed in ATEX-rated cabinets.

According to the IECEx Scheme framework, equipment for use in explosive atmospheres must be certified by an IECEx-accredited Certification Body and carry a formal Certificate of Conformity traceable to the issuing body. EVST’s XR-EX holds this documentation and provides it as part of the standard equipment package for project CE marking support.

When ATEX Certification Is Required

ATEX or IECEx certification is required when:

• The paint booth uses solvent-borne (organic-solvent) coatings with a flashpoint below 60°C
• The booth is classified Zone 1 or Zone 2 by the site’s area classification study
• Local regulations (EU, Middle East, Southeast Asian markets following IECEx equivalence, or U.S. Class I Division 1/2 NEC zones) mandate it for equipment within the hazardous area boundary
• The insurance underwriter or EHS team requires hazardous-area certification as a procurement condition

Waterborne-only booths with adequate ventilation may fall outside Zone 1/2 classification depending on the local regulatory body’s interpretation. EVST recommends confirming the zone classification with your EHS engineer before specifying robot type.

EVST’s Explosion-Proof Heritage

EVST delivered China’s first ATEX/IECEx certified collaborative robot. This is not a late-stage certification add-on; the XR-EX was designed from the joint level with explosion-proof requirements built into its mechanical and electrical architecture. For a full technical breakdown of the XR-EX series, see our dedicated guide: Explosion-Proof Collaborative Robot: ATEX/IECEx XR-EX Series.

Paint Process and Material Compatibility

In practice, EVST has commissioned painting cells running five distinct coating media types across multiple industries. The robot hardware is compatible across all five; the cell design (gun selection, color-change circuit, booth class) varies by media.

Spray Gun and Applicator Integration

EVST painting cells support applicators from Graco, Sames, Wagner, and 3M, covering standard air spray guns, HVLP guns, electrostatic spray guns, and rotary bell cup systems. Gun selection follows coating type and transfer efficiency target. According to industry observations on painting automation, rotary bell cup applicators achieve 85–95% transfer efficiency on waterborne base coat and clear coat, compared with 25–40% for conventional air spray guns. The difference directly affects VOC output, material cost, and regulatory compliance under ISO 9445 surface coating standards. EVST’s applications team confirms gun compatibility and recommends a cup or gun model based on your paint specification before issuing a quotation.

Coating Media Coverage

Color Change and Flow Rate Control

For operations running multiple colors per shift, EVST integrates color-change valve blocks (Graco or Sames multi-color manifolds) with automated solvent flush cycles. Changeover time targets 60–120 seconds for solvent systems and 90–180 seconds for waterborne, depending on line length and paint viscosity. Flow rate control is managed at the robot controller level, synchronized with robot speed to maintain consistent film thickness through acceleration and deceleration zones of the spray path.

Applications and Industries

According to industry observations on robotic painting adoption, surface coating quality defects (runs, sags, thin film, overspray contamination) account for a significant share of automotive and consumer-goods rework costs. Consistent robot-controlled spray parameters reduce film-thickness variation and cut rework substantially compared with manual spray booths. EVST painting cells serve five primary industry segments.

Vision-Guided and Teach-Free Painting

Traditional painting robot programming requires a specialist to manually teach each spray path using a pendant, a process that can take days for complex parts and must be repeated for each new SKU. EVST addresses this with two automation layers: 3D vision-guided workpiece positioning for precision path registration, and the EVST teach-free painting system (TSRC100-7) that removes programming knowledge as a bottleneck entirely.

EVST Teach-Free System: Operator-Demonstrated Spray Path

The EVST teach-free painting system (TSRC100-7) works on a direct demonstration principle. A paint technician picks up a handheld spray gun wired to the system and sprays the part as they would normally. The 9-axis control system captures the full trajectory (speed, angle, distance, pattern overlap) and stores it as a robot program. When the production robot runs the program, it reproduces the exact path at the same parameters, with ±2–5 mm positional precision.

In practice, when we commission EVST teach-free cells, a new part can go from demonstration to production-ready in under 30 minutes. No robot programming knowledge is required. This makes the system particularly effective for operations with high SKU variety, frequent model changes, or facilities where programming specialists are not available on-site. The system’s -10°C to +75°C operating range also covers unheated or seasonally cold paint shops.

3D Vision for Workpiece Registration

For operations where parts arrive with positional variation on fixtures (common in sanitary ware and agricultural equipment coating), 3D vision scanning identifies the actual workpiece position before each spray cycle and offsets the robot path accordingly. This eliminates the need to re-teach when fixtures wear or parts are loaded at slightly different angles, maintaining film thickness consistency across the full production shift.

Multi-Axis Real-Time Linkage

The EVST teach-free system supports up to 12 additional axes of synchronized motion (conveyor, turntable, or gantry) through EtherCAT without an external PLC. Real-time axis linkage means the robot spray path adjusts continuously to workpiece motion on a moving conveyor, which is necessary for automotive body-in-white painting lines where stopping the conveyor to spray is not an option.
