Tuoxingchen TRH020-1000-400-H model positioning and working condition adaptation
Tuoxingchen TRH020-1000-400-H The SCARA horizontal multi-joint robot model belongs to the Topstar SCARA (TRH 10-20kg / TRD direct drive), with a rated load of 20kg and a motion radius of 1000mm. TOPSTAR's technical foundation is automation around injection molding: the robot arm and injection molding machine ecosystem are mature, and the STAR series has high penetration in injection molding workshops; The control platform is the Topstar controller (injection molding online ecosystem), and the program ecosystem is graphical programming (user-friendly injection molding process interface).
From the perspective of working condition adaptation, the typical use for medium-duty load (20kg) positioning is:Welding, machine tool wiring, medium-sized palletizing, and die-casting part removal。 The medium reach (1000mm) meets the needs of conventional workstations, offering flexible single-station layout. This level is the main stage for welding and loading; when selecting a positioner or dual stations, pay attention to the total cycle time and interference zone planning.
| Parameters | Engineering interpretation and usage recommendations |
|---|---|
| Rated load capacity: 20kg | It is recommended to reserve a load margin of 20%–30%; Verification is made by combining end self-weight + workpiece + imbalanced load inertia, especially sensitive to high-speed conditions |
| Movement radius: 1000mm | Determine the radius of the workcell layout: bins, tooling, and fences are bounded by maximum arm span + safety distance; Verify the accessibility of each pick-and-place point during cross-station service |
| Controller: Topstar controller (injection molding online ecosystem) | Decide on the process ecosystem, spare parts channels, and second-hand residual value; Currently, spare parts channels are smooth, and repair and upgrade paths are mature |
Control systems and common failure modes
The Topstar TRH020-1000-400-H is equipped with the Topstar controller (injection molding online ecosystem) controller, featuring graphical programming in both programming language and development environment (user-friendly injection molding process interface). Maintenance of this generation of control platforms focuses on three basic components: power, storage, and cooling—most "sudden downtime" can be detected in advance when preventive maintenance is in place.
| Failure mode | Typical performance | Disposal recommendations |
|---|---|---|
| Injection molding machine connection signal fault | Injection molding machine connection signal fault (interface protocol and aging) | Included as a mandatory inspection item for annual maintenance, with spare parts stocked in advance |
| Driver and motor abnormalities | Driver and motor abnormalities | Initial interpretation of alarm codes by reference with manuals, remote diagnosis allows for early positioning |
| Leaks in the air pipe and vacuum system | Leaks in air pipes and vacuum systems (high-frequency injection molding parts) | Daily inspection coverage, with abnormal trends (abnormal noises/temperature rise/errors) recorded |
| The crossbeam and guide rail are worn | Wear of beams and guideways (transverse type models) | Quarterly dust removal maintenance and cabinet temperature monitoring |
| Maintenance projects | Cycle recommendations | Key points |
|---|---|---|
| Quarterly inspection of vacuum suction cups and air circuit seals | Quarterly | Quarterly inspection of vacuum suction cups and air circuit seals |
| Guide rail lubrication and wear inspection | According to the manufacturer's manual cycle | Guide rail lubrication and wear inspection |
| Annual testing of online interface signals | Year | Annual testing of online interface signals |
| Cable and drag chain inspection | every six months | Insulation, shielding, and bending radius inspection of power and encoder lines, as well as wear of cables inside the drag chain, are the main causes of intermittent faults |
| Zero point and accuracy retest | Every year | Repeatability measured by dial gauges or laser trackers, drift trend digitization—accuracy degradation can be seen six months in advance |
| Control cabinet dust removal and fans | Every quarter | Filter cleaning, fan speed and noise checks, cabinet temperature recording; Dust environments shorten the cycle |
Henghuan's service capabilities for Tuoxingchen TRH020-1000-400-H

Common issues with this device
Is it easy to find spare parts for Tuoxingchen TRH020-1000-400-H?
TOPSTAR: The spare parts channel for this generation is smooth; we have in-stock or short-cycle channels for standard parts such as drivers, power modules, batteries, and teach pendant components; Vacuum suction cups and air circuit seals are recommended to be configured according to the annual maintenance contract for quarterly inspection consumables.
With a nominal load of 20kg, how much can it actually handle?
The rated load is the static load limit of the flange surface. In actual selection, three factors must be considered: the self-weight of the end fixture (vacuum suction cup groups or grippers often account for 2–5kg), the inertia generated by the workpiece offload (checked according to the inertia ratio when the center of gravity deviates from the flange center), and the dynamic load during high-speed movement. The conventional engineering practice is to keep the "end + workpiece" within 70%–80% of the rated value to ensure cycle time and service life.
If the equipment's accuracy deteriorates after several years of use, how can it be restored?
According to the inspection order: first check whether the zero point is drifting (common after collision or battery depletion), then perform zero calibration; Check the reducer's return error (actual measurement of forward and reverse positioning deviation; if exceeded, disassemble or replace); Then check the installation base fastening and foundation settlement; Finally, trajectory compensation parameter restructuring. Most accuracy issues can be mostly restored after calibration and maintenance, so there is no need to rush into major repairs—we first release the inspection data before deciding on the plan.
Is the used Tuoxingchen TRH020-1000-400-H worth buying?
Injection molding workshops have a large volume of retirements, and second-hand transactions within the same industry are fast; Procurement outside injection molding conditions requires assessment and control of ecological adaptation. Three essential items for second-hand procurement: comprehensive inspection reports (axial accuracy, driver status, insulation and battery), maintenance history and operating hours, controller generation, and software license integrity. Every used machine we sell comes with inspection records and a 12-month warranty, and we can also accept third-party inspections designated by customers.
