[0002] With the rapid development of modern smart home appliances and the continuous improvement of residents' living standards, smart curtain systems can use torque motors to automatically control the winding and release of curtains. Manufacturers need to conduct special performance tests on the torque motors in smart curtain systems, including electrical and mechanical properties, specifically insulation, voltage resistance, power, torque, and speed performance. To implement the production process requirements of efficient production and efficient testing, it is necessary to design a special, efficient, and automatic test equipment to help achieve efficient testing of the torque motors in smart curtain systems and improve the production efficiency of torque motors. Summary of the Invention

[0003] Purpose of the invention: In view of the background technology that enables efficient detection of torque motors of smart curtain equipment and improves the production efficiency of torque motors, we design a torque motor performance testing machine that uses a dedicated positioning carrier to independently support the torque motor to be tested and feed it to a multi-station test assembly for dual-path and parallel inspection. Performance tests are carried out on, but not limited to, the electrical performance, torque, and speed items of the torque motor. The positioning carrier can be reset and reused through the return line, which is practical and convenient.

[0004] The technical solutions adopted to solve the above problems are:

[0005] A torque motor performance testing machine includes a feed conveyor belt, a loading conveyor assembly, a positioning carrier for supporting the torque motor to be tested, a multi-station testing assembly, a unloading conveyor assembly and a return line.

[0006] The positioning carrier is placed on the feed conveyor belt and automatically transferred to the loading conveyor assembly. The loading conveyor assembly includes a set of loading conveyor belts and a loading sliding screw pair. After the loading conveyor belt is connected to the positioning carrier on which the torque motor is placed, the loading sliding screw pair slides and loads the material to the multi-station test assembly.

[0007] The upper end of the positioning carrier is provided with a positioning seat of the torque motor, a detachable connecting socket, a pin seat electrically connected to the connecting socket, and positioning blocks on both sides of the lower end of the positioning carrier.

[0008] The multi-station test assembly is provided with two groups of symmetrical stepping conveyors, a lifting test platform, an electrical performance test module, a speed test module and a torque test module driven by an electric lifting screw pair to realize lifting and lowering actions, as well as a limit assembly for fixing the positioning carrier and a docking probe assembly electrically connected to the pin seat. The stepping conveyor drives the positioning carrier to feed to each test module at a uniform speed and step by step. Several test modules are evenly spaced and arranged in parallel on both sides of the lifting test platform. The middle part of the lifting test platform is fixedly connected to the screw slider of the electric lifting screw pair and is driven to perform lifting and sliding actions. Guide column and guide sleeve assemblies are also provided on both sides of the lifting test platform to stabilize the lifting action.

[0009] The electrical performance test module includes a rotating motor fixed on a lifting test platform, a guide positioning assembly, and a test pin assembly. The rotating motor is positioned by a motor bracket and is facing the main shaft of the torque motor to be tested. A rubber knob seat is provided below the main shaft of the rotating motor and is engaged with the main shaft of the torque motor. The rubber knob seat includes a rubber cylindrical section in the middle and a connecting seat at the bottom. The rubber cylinder is elastic and can play a role in torsional buffering impact force. A card slot is provided in the middle of the connecting seat, and the card slot is engaged with the main shaft of the torque motor. When the torque motor starts to rotate after receiving an electrical signal, the rotating motor provides resistance to reverse rotation, and the pin provided by the test pin assembly is short-circuited with the brush pole on the upper part of the torque motor. The withstand voltage performance of the torque motor coil is tested with the cooperation of an external instrument.

[0010] The speed test module includes a static motor, a transmission shaft, a rubber twist seat, and a guide positioning assembly. The static motor is positioned by a motor bracket and is aligned with the main shaft of the torque motor to be tested. The main shaft of the static motor is connected to the rubber twist seat through a transmission shaft. The rubber twist seat cooperates with the main shaft of the torque motor. When the static motor is not powered, the external speed tester is used to test the speed of the static motor driven by the torque motor to obtain the speed performance parameters under load.

[0011] The torque test module includes a reduction motor, a torque sensor, a transmission shaft and a rubber twist seat, as well as a guide and positioning component. The transmission shaft is connected to the reduction motor main shaft, the torque sensor and the rubber twist seat. The rubber twist seat cooperates with the main shaft of the torque motor. Under the detection of the torque sensor, the torque performance of the rotating torque motor main shaft is tested.

[0012] The torque motor that has been tested is unloaded to the return line through the unloading conveying assembly. The return line includes an automatic lifting platform, a lifting slide and a return conveyor belt.

[0013] The docking probe assembly is electrically connected to the pin socket provided on the positioning carrier, and includes several probes, a docking block, a docking cylinder and a cable connector. Several wires led out of the cable connector are connected to the probes one by one, and the cable connector is externally connected to a power supply.

[0014] Furthermore, the feed conveyor belt is provided with a transmission motor, a bevel gear group, two front and rear feed shafts and a transmission belt. The middle part of the feed shaft is connected to the bevel gear group. The bevel gear group is provided with rotational power by the transmission motor to drive the feed shaft to rotate. A transmission belt is sleeved between the feed shafts.

[0015] Furthermore, the structural principles of the feed conveyor belt, loading conveyor belt and stepping conveyor belt are the same.

[0016] Furthermore, the guide and positioning assembly includes a transverse guide roller fixed under the motor bracket and a vertical positioning roller controlled by the lifting of the positioning cylinder, which guides the feeding and positioning of the elliptical outer wall of the torque motor.

[0017] Furthermore, the limiting assembly is arranged below the stepping conveyor belt, and includes a supporting cylinder and two sets of front and rear limiting pressing cylinders, and the pressing cylinders are pressed against the positioning block to implement limiting.

[0018] Furthermore, positioning holes are provided at the four corners of the pin seat, and the positioning holes cooperate with the positioning pins of the docking probe assembly to implement precise positioning docking.

[0019] The beneficial effects of the present invention are:

[0020] 1. This torque motor performance tester uses a dedicated positioning carrier to independently support the torque motor to be tested and feed it to the multi-station test assembly for dual-path inspection. Performance tests are carried out on, but not limited to, the torque motor's electrical performance, torque, and speed.

[0021] 2. Dual-line parallel synchronous detection can improve detection efficiency and adapt to the high efficiency of production line production capacity;

[0022] 3. The setting of the rubber twist seat can fully protect the torque motor from the large current shock generated by the instantaneous start and stop, and protect the internal coil;
