Before performing the multi-station performance detection, manually check whether each test probe 29 can operate normally. After confirming that it is operating normally, transfer the battery to the bottom of the test probe 29, and then rely on the probe height adjustment component 30 to drive the test probe 29 to descend for testing.

[0026] like Figure 1-Figure 4 As shown, a multi-station test bench for lead-acid battery production includes a transmission table 1, on which side baffles 12 are vertically installed in pairs, and a step-type electric conveyor belt 3 is horizontally installed between the two side baffles 12. The lead-acid battery body 11 is placed horizontally on the step-type electric conveyor belt 3 and is transmitted by the step-type electric conveyor belt 3. A plurality of supporting rotating columns 2 are rotatably connected between the two side baffles 12, and the plurality of supporting rotating columns 2 are distributed on the lower side of the step-type electric conveyor belt 3. The supporting rotating columns 2 are used to support the bottom of the step-type electric conveyor belt 3 to prevent it from collapsing; two support rods are vertically fixedly connected to the upper sides of the two side baffles 12, and a data testing device 5 is commonly connected to the top of the two support rods. The data testing device 5 is a model ZHCH558 battery pack online monitoring device. The data testing device 5 is electrically connected to a plurality of rod-shaped detection probes 6. The two sides of the data testing device 5 are vertically fixedly connected with first electric telescopic rods 7. The telescopic ends of the two first electric telescopic rods 7 are horizontally fixedly connected with a first connecting cross bar 9. A plurality of rod-shaped detection probes 6 are laterally distributed on the lower side of the first connecting cross bar 9. Each rod-shaped detection probe 6 is electrically connected to the data testing device 5. When a plurality of lead-acid battery bodies 11 are transferred to the test position along the stepping electric conveyor belt 3, the first electric telescopic rod 7 is just extended downward, so that the plurality of rod-shaped detection probes 6 distributed on the first connecting cross bar 9 are lowered to contact the electrode ends of each lead-acid battery body 11 to perform battery-related performance tests; the rod-shaped detection probes 6 are connected to a repeated self-test mechanism;

[0027] The repeated self-inspection mechanism includes a connecting guide rail 13, two support rods are horizontally fixedly connected with the connecting guide rail 13, the ends of the two connecting guide rails 13 away from the transmission platform 1 are commonly fixedly connected with a self-inspection battery pack 18, a connecting cross plate 10 is horizontally slidably connected between the two connecting guide rails 13, and a plurality of telescopic connecting rods 16 are horizontally and equidistantly fixedly connected to the front side of the connecting cross plate 10, the telescopic connecting rods 16 are insulating rubber bodies, a first spring 15 is connected between the telescopic end and the fixed end of each telescopic connecting rod 16, a movable conductive block 14 is fixedly connected to the telescopic end of each telescopic connecting rod 16, each movable conductive block 14 is electrically connected to the electrode end of the self-inspection battery pack 18, and each movable conductive block 14 is in contact with the corresponding rod-shaped detection probe 6, and the rod-shaped detection probe 6 is at When in the folded position, each movable conductive block 14 remains in contact with the lower side of the rod-shaped detection probe 6 at the corresponding position. At this time, the telescopic connecting rod 16 and the first spring 15 are in a compressed state. The rebound force of the first spring 15 ensures that the movable conductive block 14 is tightly attached to the rod-shaped detection probe 6. In this way, the data testing equipment 5 is convenient to electrically connect the self-test battery pack 18 by relying on the contact between the rod-shaped detection probe 6 and the movable conductive block 14. The self-test battery pack 18 is a battery pack with no problems and normal functions. In this way, the data testing equipment 5 can directly detect valid data without abnormalities; the upper side of the connecting cross plate 10 is movably connected to a linkage rod 17 through a hinge, and the upper side of the first connecting cross bar 9 is horizontally fixedly connected to a second connecting cross bar 8, and the end of the linkage rod 17 is movably connected to the second connecting cross bar 8 through a hinge.

[0028] The first electric telescopic rod 7 performs telescopic movement intermittently, and whenever the stepping electric conveyor belt 3 transfers a group of lead-acid battery bodies 11 to the bottom of the test position, the first electric telescopic rod 7 extends downward, pushing the multiple rod-shaped detection probes 6 on the first connecting cross bar 9 to descend and dock with the electrode ends of the multiple lead-acid battery bodies 11 to achieve electrical connection, and relying on the data testing equipment 5 to test multiple lead-acid battery bodies 11 at the same time, to achieve multi-station testing, and when the first electric telescopic rod 7 extends downward to push the rod-shaped detection probe 6 to descend, the second connecting cross bar 8 also descends synchronously, and during this process, the second connecting cross bar 8 pushes the connecting cross plate 10 to slide along the connecting guide rail 13 away from the rod-shaped detection probe 6 through the linkage rod 17, and when the rod-shaped detection probe 6 contacts the electrode end of the lead-acid battery body 11 to be tested, the activity The movable conductive block 14 is separated from the rod-shaped detection probe 6. When the first electric telescopic rod 7 contracts, the second connecting cross bar 8 is synchronously raised. During this process, the second connecting cross bar 8 pulls the connecting cross plate 10 to slide back along the connecting guide rail 13 through the linkage rod 17. During the sliding back of the connecting cross plate 10, the movable conductive block 14 is driven by the telescopic connecting rod 16 to squeeze and contact the rod-shaped detection probe 6. In this way, every time the rod-shaped detection probe 6 descends to detect a group of lead-acid battery bodies 11 and then rises, the rod-shaped detection probe 6 is re-connected with the movable conductive block 14, which facilitates the data testing equipment 5 to be electrically connected to the self-test battery pack 18 for self-test. If the data testing equipment 5 detects abnormal data when docking with the self-test battery pack 18, it can be determined that there may be a problem with the data testing equipment 5, and the subsequent lead-acid battery bodies 11 are tested in time. Stop the device 5.

[0029] A pair of through-holes 4 are provided on the side baffle plate 12 at one side of the transmission platform 1. The position between the two through-holes 4 is a test position. A connecting column 25 is vertically rotatably connected in the two through-holes 4. A coil spring is connected between the rotating end of the connecting column 25 and the inner wall of the through-hole 4. When the connecting column 25 rotates, the coil spring tightens to generate a rebound force, which facilitates the rotation and reset of the connecting column 25. A sliding push plate 22 is inserted through the two connecting columns 25 for horizontal sliding. There is a gap between the connecting column 25 and the inner walls on both sides of the through-hole 4, which facilitates the sliding push plate 22 to rotate by relying on the connecting column 25. A second spring 23 is connected between the sliding push plate 22 and the connecting column 25. The through-hole 4 A second electric telescopic rod 20 is horizontally fixedly connected to the outer wall of the side baffle 12 at the position, and the second electric telescopic rod 20 performs telescopic movement intermittently. Whenever a group of lead-acid battery bodies 11 is transferred to the test position, the second electric telescopic rod 20 performs a telescopic movement. A horizontal push plate 21 is horizontally fixedly connected to the telescopic end of the second electric telescopic rod 20. The horizontal push plate 21 is aligned with two sliding push plates 22. The two sliding push plates 22 are connected to an oblique guide block 27 on one side of the end away from the connecting rotating column 25. The side baffle 12 at the position of the through hole 4 is vertically fixedly connected with a limited stopper 19 in pairs. The limited stopper 19 is aligned with the oblique guide block 27, and the two sliding push plates The roller 26 is rotatably connected to the end of the sliding push plate 22 away from the connecting rotating column 25, and the roller 26 facilitates the end of the sliding push plate 22 to slide relative to the horizontal push plate 21. Whenever a group of lead-acid battery bodies 11 are transferred to the test position along the stepping electric conveyor 3, before the first electric telescopic rod 7 is started, the second electric telescopic rod 20 is operated first, and the second electric telescopic rod 20 is extended, so that the horizontal push plate 21 pushes the two sliding push plates 22, and the sliding push plates 22 slide through the connecting rotating column 25 and slide to both sides of the test position, that is, both sides of the multiple lead-acid battery bodies 11 to be tested. As the sliding push plate 22 slides horizontally, the inclined guide blocks 27 on the sliding push plate 22 are gradually Gradually approaching the limit stop rod 19, when the inclined guide block 27 is squeezed onto the limit stop rod 19, the sliding push plate 22 rotates by relying on the connecting rotating column 25 due to the squeezing, and as the horizontal push plate 21 continues to push, the two sliding push plates 22 pass through the ends on both sides of the test position and then synchronously rotate and push toward the middle, so as to push the multiple lead-acid battery bodies 11 that stay at the test position toward the center of the test position at the same time, and adjust the position. The adjusted position is exactly the position where the electrode end of the lead-acid battery body 11 is aligned with the rod-shaped detection probe 6 up and down, which is convenient and effective for testing, and avoids the existence of gaps between the same group of multiple lead-acid battery bodies 11 during the transmission process, resulting in position deviation and affecting the detection.

[0030] The working principle of the present invention is as follows: the lead-acid battery bodies 11 are placed one by one on the stepping electric conveyor belt 3, and are transported by the stepping electric conveyor belt 3. Whenever a group of lead-acid battery bodies 11 are transported to the test position along the stepping electric conveyor belt 3, the second electric telescopic rod 20 runs first, and the second electric telescopic rod 20 is extended so that the horizontal push plate 21 pushes the two sliding push plates 22, and the sliding push plates 22 slide through the connecting rotating column 25 and slide to both sides of the test position, that is, both sides of the multiple lead-acid battery bodies 11 to be tested. As the sliding push plate 22 slides horizontally, the inclined guide block 27 on the sliding push plate 22 gradually approaches the limit stopper 19. When the inclined guide block 27 is pressed onto the limit stopper rod 19, the sliding push plate 22 rotates by relying on the connecting rotating column 25 due to the pressing, and as the horizontal push plate 21 continues to push, the two sliding push plates 22 pass through the ends on both sides of the test position and then synchronously rotate and push toward the middle, so as to push the multiple lead-acid battery bodies 11 staying at the test position toward the center of the test position at the same time, and adjust the position. The adjusted position is exactly the position where the electrode end of the lead-acid battery body 11 is aligned with the rod-shaped detection probe 6 up and down, which is convenient and effective for testing, and avoids gaps between the same group of multiple lead-acid battery bodies 11 during the transmission process, resulting in position deviation and affecting the detection;

[0031] After the position of the lead-acid battery body 11 is adjusted, the first electric telescopic rod 7 begins to extend downward, pushing the multiple rod-shaped detection probes 6 on the first connecting cross bar 9 to descend and dock with the electrode ends of the multiple lead-acid battery bodies 11 to achieve electrical connection, and relying on the data testing equipment 5 to test multiple lead-acid battery bodies 11 at the same time, to achieve multi-station testing, and when the first electric telescopic rod 7 extends downward to push the rod-shaped detection probe 6 to descend, the second connecting cross bar 8 also descends synchronously. During this process, the second connecting cross bar 8 pushes the connecting cross plate 10 to slide along the connecting guide rail 13 away from the rod-shaped detection probe 6 through the linkage rod 17, and when the rod-shaped detection probe 6 contacts the electrode end of the lead-acid battery body 11 to be tested, the movable conductive block 14 detaches from the rod-shaped detection probe 6. When an electric telescopic rod 7 contracts, the second connecting cross bar 8 rises synchronously therewith. During this process, the second connecting cross bar 8 pulls the connecting cross plate 10 to slide back along the connecting guide rail 13 through the linkage rod 17. During the sliding back of the connecting cross plate 10, the movable conductive block 14 is driven by the telescopic connecting rod 16 to squeeze and contact the rod-shaped detection probe 6. In this way, every time the rod-shaped detection probe 6 descends to detect a group of lead-acid battery bodies 11 and then rises, the rod-shaped detection probe 6 re-docking with the movable conductive block 14, which facilitates the data testing equipment 5 to electrically connect the self-test battery pack 18 for self-test. If the data testing equipment 5 detects abnormal data when docking with the self-test battery pack 18, it can be determined that there may be a problem with the data testing equipment 5, and the subsequent lead-acid battery bodies 11 can be stopped in time.

[0032] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
