[0046] Work process:

[0047] Material feeding and conveying:

[0048] The equipment is equipped with a unified control system that coordinates the operation of the first conveyor belt 1, the second conveyor belt 4, the third conveyor belt 7, and the fourth conveyor belt 8. After startup, the first drive motor unit 2 drives the first conveyor belt 1 to move, conveying the container 9 carrying the power supply to be tested 10 to directly below the placement mechanism. At this time, the first slider 33 of the placement mechanism is in the initial standby position under the constraint of the limit rod 34.

[0049] Container transfer:

[0050] The second drive motor 37 of the placement mechanism is started, which drives the rotating rod 39 to rotate through the gear set 38, causing the roller 391 to roll along the slide bar 32, and driving the first slider 33 to move directly above the container 9;

[0051] The first hydraulic rod 35 is extended, pushing the first connecting block 392 downward, and the container 9 is adsorbed by the vacuum suction cup 393.

[0052] The first hydraulic rod 35 retracts and resets, the second drive motor 37 rotates in the opposite direction, driving the first slider 33 to move along the slide rod 32 to above the second conveyor belt 4, releasing the vacuum suction cup 393 to place the container 9 on the second conveyor belt 4, and the guardrail 5 prevents the container 9 from falling during transport.

[0053] Pre-test positioning and fixation:

[0054] The second conveyor belt 4 transports the container 9 to the testing station directly below the testing mechanism. The control system triggers the camera 696 to start, which collects real-time position images of the container 9 and the power supply 10 under test, and transmits the image data to the image recognition module of the control system.

[0055] The image recognition module analyzes the image data, calculates the offset of container 9 and the actual position of the electrode of the power supply under test 10, and generates positioning correction parameters.

[0056] According to the correction parameter command, the control system extends the fifth hydraulic rod 68, pushing the second connecting block 693 down along the slide rail 691 to the preset height;

[0057] The sixth hydraulic rod 694 extends according to the offset data, pushing the correction plate 695 closer to the container 9 until it touches the container 9 to complete the position correction;

[0058] The seventh hydraulic rod 699 extends, driving the clamping block 697 to tighten inward, firmly clamping the container 9 and preventing displacement due to vibration during testing.

[0059] Charge / discharge detection (combination of coarse and fine adjustment):

[0060] Coarse adjustment stage: Start the extension of the second hydraulic rod 62, which drives the second connecting plate 63, connecting rod 65 and third connecting plate 64 to move down as a whole, so that the independent test unit 67 can quickly approach the power supply under test 10.

[0061] Fine-tuning stage: The camera 696 acquires real-time images again. The control system extends the fourth hydraulic rod 66 according to the precise position command of the electrode, pushing the independent test unit 67 to make millimeter-level fine-tuning and move it down, so that the connection plug 6991 on the lower side of the independent test unit 67 is precisely inserted into the electrode of the power supply under test 10.

[0062] Independent test unit 67 starts the charge and discharge test, records the performance parameters of the power supply under test 10, and feeds back the test results to the PLC controller in real time.

[0063] Sorting and conveying:

[0064] After the test is completed, the fourth hydraulic rod 66 and the second hydraulic rod 62 retract in sequence, driving the independent test unit 67 to reset; the seventh hydraulic rod 699, the sixth hydraulic rod 694, and the fifth hydraulic rod 68 retract in sequence, releasing the clamping and limiting of the container 9;

[0065] The control system instructs the second conveyor belt 4 to operate according to the detection results, transports the container 9 to the bottom of the placement mechanism, and sends a sorting instruction to the placement mechanism;

[0066] Actions of the placement mechanism after receiving the instruction:

[0067] If the power supply under test 10 fails the test, the placement mechanism will move the container 9 to the fourth conveyor belt 8, which will then transport it to the maintenance area.

[0068] If the power supply to be tested 10 passes the test, the placement mechanism will move the container 9 to the third conveyor belt 7, which will then transport it to the qualified product storage area.
