[0002] A stator performance testing machine is a specialized piece of equipment used for comprehensive performance testing of motor stators. It is widely used in motor manufacturing, quality control, and product development to ensure that the electrical performance and safety reliability meet standards. Existing stator performance testing machines typically transport stators via conveyor belts, and the stators are manually transferred from the conveyor belt to positioning blocks for positioning. Then, a lifting and exposed testing component is activated to test the stator. After testing, the results are manually observed and classified. However, this structure, due to the exposed testing component and reliance on manual loading and classification, is prone to problems such as human fatigue leading to decreased production efficiency and compromised production quality. Furthermore, the test results are susceptible to inaccurate resistance readings due to the influence of ionized water ions in the air. Therefore, improvements are needed to address these issues.

Then, connect the connector block through the wire and connect it to each electrical structure from the other end. S2, When stator inspection is required, the stator to be inspected is first placed on the first conveyor belt, and then the second motor is started to control the stator to move. At this time, a robotic arm control box is started to cycle through the preset program to start the first motor at the front end to control the gear to rotate, and then control the moving seat to move the robotic arm in the X-axis direction through the rack meshing with it.

[0021] Working principle: In this embodiment, the present invention also proposes a test control system method for a test machine used for stator performance testing, including the following steps: Step 1: Before using the testing machine, the equipment initialization preparation work must be completed. Connect all electrical equipment, such as the two air pumps 15, the robotic arm control box 13, the data processor 17, and the display panel 18 installed on the base 1, to the power supply to ensure a stable power supply. Then, make precise connections between the pipelines and circuits: connect the air extraction port 12 at the rear of the positioning block 11 on the workbench 5 to the air pump 15 through the vacuum pipe to build a vacuum path. Connect the multiple air pipes passing through the preset wiring holes to the air circuit integration block 36 in the slots of the workbench 5 and the machine base 2, and then transfer them to the first slide cylinder 6 and the second slide cylinder 9 on the same side through the air circuit integration block 36 to ensure the power transmission of the pneumatic components. In terms of circuit connection, connect the two vacuum sealing connectors 35 and the data processor 17 on the support plate 16 through the live wire and the neutral wire, respectively, and then connect them to the wiring block 8 on the top plate 7 through the wires, and finally extend to each electrical structure to complete the closed-loop construction of the detection and control circuit, laying the foundation for subsequent operations. Step 2: After the equipment is ready, start the stator loading process. Place the stator to be tested on the first conveyor belt 32 at the top of the first support 28, start the second motor 30, and its output shaft drives the first rotating shaft to rotate through the coupling, thereby driving the first conveyor belt 32 to operate and realize the automatic conveying of the stator. At this time, start the front-end robotic arm control box 13 and control the material picking component on the support table 19 to work in a cycle according to the preset program: the drive shaft of the first motor 25 passes through the moving seat 22 and connects to the gear 26. The gear 26 meshes with the rack 27 in the guide rail 20 to drive the moving seat 22 to move along the guide rail 20 in the X-axis direction. At the same time, the dust covers 21 on both sides of the moving seat 22 extend and retract for protection. The robotic arm 24 on the mounting base 23 on one side of the moving seat 22 starts synchronously, accurately picks up the stator on the first conveyor belt 32, and transfers it to the positioning block 11 on the top slide 10 of the worktable 5. The positioning groove on the top surface of the positioning block 11 matches the outline of the stator to achieve preliminary positioning and complete the stator loading operation. Step 3: After the stator is loaded, the sealing test stage begins. The second slide cylinder 9 is activated, its slide moving the slide block 10 along the slide rail on the top surface of the worktable 5 in the Y-axis direction until the stator is accurately positioned directly below the top plate 7, completing the precise calibration of the stator's test position. Then, the first slide cylinder 6 is activated, its slide moving the top plate 7 up and down via a connecting plate. When the conductive plate on the surface of the top plate 7 and the slide block 10 makes full contact with the stator, a current path is formed inside the stator. Next, the electric push cylinder 3 on the top surface of the machine platform 2 is activated, its output shaft passing through the machine platform 2 and driving the sealing cover 4 down via a coupling until the sealing cover 4 lowers the worktable 5. The slide rail, slide block 10, positioning block 11, top plate 7 and other structures are completely enclosed, and the second sealing ring on the bottom surface of the sealing cover 4 is tightly fitted with the top surface of the workbench 5. At the same time, the first sealing ring between the air circuit integration block 36 and the slot ensures the sealing of the pneumatic pipeline, creating a sealed detection space. The air pump 15 is started, and the vacuum pipe connected to the air extraction port 12 is used to evacuate the inside of the sealing cover 4. During this period, the vacuum sealing connector 35 ensures that the circuit works normally in a vacuum environment. The data processor 17 in the mounting slot synchronously detects the current change in the stator in real time and presents the detection data intuitively through the display panel 18 on the front end of the machine 2. Step four: After the stator performance test is completed, the data processor 17 performs precise analysis on the collected current data, determines whether the stator is qualified according to preset standards, and completes the classification. Then, the data processor 17 transmits the classification results to the back-end robotic arm control box 13. This control box drives the back-end material handling component to perform the unloading operation according to a preset program: if the stator is qualified, the control unit 24 drives the back-end robotic arm 24 via the first motor 25 to engage the gear 26 and rack 27, moving the moving seat 22 along the guide rail 20 to the rear of the corresponding worktable 5. The robotic arm 24 then picks up the qualified stator. After being picked up, the stator is transferred to one of the second conveyor belts 33 on the upper end of the second support 29. If the stator fails the inspection, the robotic arm 24 is controlled to pick it up and transfer it to another second conveyor belt 33 separated by a partition plate. The third motor 31 is started, and its output shaft drives the second rotating shaft to rotate through the coupling, thereby driving the two second conveyor belts 33 to run synchronously, conveying the qualified and unqualified stators out of the equipment respectively, realizing classified recycling. During this process, the safety light curtains 34 on both sides above the rear end of the first support 28 continue to work to ensure the safety of the unloading operation. Step 5: After all the stators to be tested have completed the feeding, testing, and sorting process, start the equipment reset procedure: the electric push cylinder 3 drives the sealing cover 4 to rise and reset, the first slide cylinder 6 and the second slide cylinder 9 respectively drive the top plate 7 and the slide block 10 back to their initial positions, the robotic arm 24 resets to the standby state, the first conveyor belt 32 and the second conveyor belt 33 stop running, the air pump 15 stops vacuuming, and the air pressure inside the sealing cover 4 returns to normal pressure; after all components have been reset, disconnect the main power supply of the equipment and cut off the power supply of all electrical equipment to complete the entire operation process of this stator performance test.

9. A testing machine for stator performance testing according to claim 1, characterized in that: The upper ends of the second support (29) are rotatably connected to the second shafts. Two second conveyor belts (33) are sleeved on the second shafts. The two second conveyor belts (33) are separated by a partition plate that is penetrated by the second shaft. A third motor (31) is provided at the front end of one side of the second shaft. The third motor (31) is fixed to the second support (29) by a support frame, and the output shaft of the third motor (31) is connected to the second shaft by a coupling.

10. A test control system for a test machine for stator performance testing according to any one of claims 1-9, characterized in that, Includes the following steps: S1, first connect all electrical equipment to the power supply, then connect the air extraction port (12) and the air pump (15) through the air extraction pipe, and at the same time connect the multiple air pipes passing through the wire hole to the two air circuit integration blocks (36), and transfer them to the first slide cylinder (6) and the second slide cylinder (9) located on the workbench (5). At the same time, connect the two vacuum sealing connectors (35) and the support plate (16) through the live wire and the neutral wire respectively. Then connect the wiring block (8) through the wire and connect it to each electrical structure from the other end. S2, when stator testing is required, the stator to be tested is first placed on the first conveyor belt (32), and then the second motor (30) is started to control the stator to move. At this time, a robotic arm control box (13) is started to cycle through the preset program to start the first motor (25) at the front end to control the gear (26) to rotate, and then control the moving seat (22) through the rack (27) that meshes with it to move the robotic arm (24) in the X-axis direction. Then the robotic arm (24) is started to pick up the stator on the first conveyor belt (32) and put it into the positioning block (11) on the slide (10). At this time, the stator loading is completed. S3, after the stator is loaded, the second slide cylinder (9) can be started to control the slide (10) to move on the Y axis so that the stator is located directly below the top plate (7). Then the first slide cylinder (6) is started to control the top plate (7) to rise and fall. When the conductive plate on the top plate (7) and the slide (10) comes into contact with the stator, the current flows in the stator. At this time, the electric push cylinder (3) is started to control the sealing cover (4) to descend until the sealing cover (4) completely covers the structure on the worktable (5) and the bottom surface of the sealing cover (4) abuts against the worktable (5). Then the interior is sealed by the sealing ring. At this time, the air pump (15) is started to evacuate the interior through the evacuation pipe connected to the air extraction port (12). At this time, the data processor (17) located in the mounting slot synchronously detects the current change in the stator and displays the result through the display panel (18). S4. After the test is completed, the data processor (17) analyzes the test data of the stator and classifies the stator. At this time, the data is input into another robotic arm control box (13). Through the pre-set steps, if the stator is qualified, the robotic arm (24) at the rear end is controlled to move to its rear end through the first motor (25). Then the robotic arm (24) is started to clamp out the qualified stator and transfer it to the second conveyor belt (33) at the rear end. If the stator is unqualified, the robotic arm (24) is controlled to move to its rear end in the same way, and the robotic arm (24) is started to clamp out and transfer it to the second conveyor belt (33) at the front end. At the same time, the third motor (31) is started to control the two second conveyor belts (33) to rotate and send out the stator. When the remaining stators are completely tested and sent out, the equipment can be reset and the power can be disconnected.
