[0012] As can be seen from the above description of the structure of the present invention, the design starting point, concept and advantages of the present invention are: 1. When the operator starts the discharge detector, the lead-acid battery begins to discharge. The discharge detector detects the current and voltage of the lead-acid battery, and the operator can judge whether the lead-acid battery is qualified by observing the current and voltage values ​​on the display screen of the discharge detector.

[0013] 2. As the first limiting plate moves outward, the first elastic element is compressed and deformed. The first limiting plate clamps the lead-acid battery to prevent it from moving and affecting the test results.

[0014] 3. By having the operator start the servo motor, the pull rope moves the first connecting rod, the connecting frame, and the pull rod backward. The pull rod then pushes the lead-acid battery backward, eliminating the need for the operator to manually push the pull rod, thus demonstrating the automation of this device.

[0015] 4. The connecting frame pushes the third connecting rod forward and moves it backward, causing the third elastic element to deform, which reduces the impact force of the connecting frame resetting forward. Attached Figure Description

[0026] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] Example 1

[0028] See Figures 1-4 A lead-acid battery discharge detection device includes a workbench 1, an interface 2, a discharge detector 3, a transmission mechanism 4, and a pulling mechanism 5. The discharge detector 3 is installed on the rear top of the workbench 1, and five sets of interfaces 2 are installed on the front side of the discharge detector 3, with two interfaces 2 per set. The transmission mechanism 4 is installed on the workbench 1 for conveying lead-acid batteries, and the pulling mechanism 5 is installed on the workbench 1 for pulling the lead-acid batteries to move.

[0029] See Figure 1 and Figure 3 The transmission mechanism 4 includes a first support plate 402, a first fixing block 403 and a first limiting block 404. A transmission component 401 is provided on the worktable 1. The transmission component 401 consists of a motor, a roller and a transmission belt. A motor is bolted to the left front side of the worktable 1. Rollers are rotatably provided on both the left and right sides of the middle of the worktable 1. The output shaft of the motor is connected to the roller on the left. A transmission belt is wound on the roller. A first support plate 402 is provided on the transmission belt. A first fixing block 403 is connected to both the left and right sides of the middle of the first support plate 402. A first limiting block 404 is symmetrically connected to the left and right sides of the front of the first support plate 402.

[0030] See Figure 1 and Figure 4 The pulling mechanism 5 includes a connecting frame 501, a first connecting rod 502, a first fixed frame 503, and a pull rod 504. The first fixed frame 503 is welded to the front of the top of the workbench 1. The first connecting rod 502 is slidably mounted on the first fixed frame 503. The connecting frame 501 is connected to the rear end of the first connecting rod 502. Five sets of pull rods 504 are connected to the rear side of the connecting frame 501. Each set of pull rods 504 consists of two rods.

[0031] When a worker needs to perform a discharge test on a lead-acid battery, they start the motor. The motor drives the conveyor belt via a roller. The worker places the lead-acid battery between two adjacent first support plates 402. The first fixing block 403 and the first limiting block 404 secure the lead-acid battery. The conveyor belt moves the lead-acid battery to the left. When the lead-acid battery reaches the appropriate position, the worker turns off the motor, and the conveyor belt stops moving. Then, the worker pushes the first connecting rod 502 backward. The first connecting rod 502 moves the connecting frame 501 and the pull rod 504 backward. The pull rod 504 pushes the lead-acid battery backward, causing it to press against the first limiting plate 603. The first limiting plate 603 moves outward, and the first elastic element 602 is compressed. Upon deformation, the first limiting plate 603 clamps the lead-acid battery to prevent it from moving and affecting the test results. The pull rod 504 continues to push the lead-acid battery backward, and the positive and negative terminals of the lead-acid battery are inserted into the interface 2. The operator starts the discharge detector 3, and the lead-acid battery begins to discharge. The discharge detector 3 detects the current and voltage of the lead-acid battery. The operator judges whether the lead-acid battery is qualified by observing the current and voltage values ​​on the display screen of the discharge detector 3. After the lead-acid battery is tested, the operator pulls the first connecting rod 502 forward. The first connecting rod 502 drives the lead-acid battery to reset forward through the connecting frame 501 and the pull rod 504. The first elastic element 602 drives the first limiting plate 603 to reset inward. The operator then turns off the discharge detector 3.

Two identical first elastic elements 602 are connected to the left and right sides of the remaining second fixing blocks 601. The first limiting plate 603 is connected between the two first elastic elements 602 on the left and between the two first elastic elements 602 on the right.

[0034] See Figure 1 and Figure 6It also includes a power mechanism 7 for pulling the first connecting rod 502. The power mechanism 7 includes a support frame 701, a second fixed frame 702, a servo motor 703, a first winding wheel 704, a second winding wheel 705, and a pull rope 706. The support frame 701 is connected to the rear side of the top of the workbench 1, and the second fixed frame 702 is connected to the rear side of the workbench 1. The servo motor 703 is bolted to the front side of the second fixed frame 702. The first winding wheel 704 is mounted on the output shaft of the servo motor 703. The second winding wheel 705 is rotatably mounted on the front side of the support frame 701. The pull rope 706 is wound on the first winding wheel 704, and the end of the pull rope 706 passes around the second winding wheel 705 and connects to the first connecting rod 502.

[0035] See Figure 1 and Figure 7 It also includes a reset mechanism 8 for resetting the first connecting rod 502. The reset mechanism 8 includes a second limiting plate 801, a second connecting rod 802, and a second elastic element 803. The second connecting rod 802 is symmetrically welded to the left and right sides of the front side of the support frame 701. The front end of the second connecting rod 802 is connected to the second limiting plate 801. After the connecting frame 501 moves, it contacts the second limiting plate 801. The second elastic element 803 is sleeved on the first connecting rod 502. One end of the second elastic element 803 is connected to the connecting frame 501, and the other end of the second elastic element 803 is connected to the first fixed frame 503.

[0038] The operator starts the servo motor 703, which winds the pull rope 706 via the first winding wheel 704 and the second winding wheel 705. The pull rope 706 pulls the first connecting rod 502, the connecting frame 501, and the pull rod 504 backward. The second elastic element 803 deforms, and the pull rod 504 pushes the lead-acid battery backward, thus eliminating the need for manual operation of the pull rod 504 and demonstrating the automation of the device. The operator can also control the servo motor 703 to drive the first winding wheel 704 to rotate in the opposite direction. The first winding wheel 704 and the second winding wheel 705... 5. Release the pull rope 706. The second elastic element 803 then drives the first connecting rod 502, the connecting frame 501, and the pull rod 504 to return to their original position. The second limiting plate 801 restricts the position of the connecting frame 501. The connecting frame 501 presses the third connecting rod 902 and the second limiting block 904 backward. The third elastic element 903 deforms, thereby reducing the impact force of the connecting frame 501 returning to its original position. After the connecting frame 501 returns to its original position, the third elastic element 903 then drives the third connecting rod 902 to return to its original position. After the device is used, the operator turns off the servo motor 703.
