A fixed plate 18 is detachably mounted on the horizontal plate 16, and a pair of test pins 19 are mounted on the fixed plate 18. The vertical plate 17 is positioned on the side of the horizontal plate 16 away from the first conveyor belt 2, and a contact sensor 17-1 for detecting the position of the battery 20 is mounted on the vertical plate 17. The pushing assembly includes a first telescopic rod 4, a push plate 5, and a movable baffle 6. The first telescopic rod 4 is mounted on the workbench 1 and located on one side of the first conveyor belt 2. The first telescopic rod 4 is parallel to and located on the fixed baffle 8. On the side of the first conveyor belt 2, the push plate 5 is detachably mounted on the telescopic end of the first telescopic rod 4, and the movable baffle 6 is mounted on the push plate 5 and located on the side away from the fixed baffle 8; a groove 4-1 is provided on the telescopic end of the first telescopic cylinder, and a locking block 5-1 is provided on the push plate 5, the locking block 5-1 being inserted into the groove 4-1; each set of limiting components includes a first limiting plate 10, a second limiting plate 10-1, a pair of limiting rods 11, a threaded rod 12, and a shaft locking device 13. The first limiting plate 10 is located on the side of the second side plate 9 near the second conveyor belt 3, the pair of limiting rods 11 pass through and slide on the second side plate 9 and their ends are connected to the first limiting plate 10, the threaded rod 12... The rod 12 is threadedly connected to the second side plate 9 and its end is rotatably connected to the first limiting plate 10. The shaft locking device 13 is set on the second side plate 9 to lock and fix the threaded rod 12. The second limiting plate 10-1 is set at the end of the first limiting plate 10 near the first conveyor belt 2. The second limiting plate 10-1 is set at a certain angle to the first limiting plate 10. The horizontal plate 16 has a through hole 16-1. The horizontal plate 16 has two rows of threaded holes 16-2 on both sides of the through hole 16-1. The fixing plate 18 is detachably set on the horizontal plate 16 by bolt thread in the threaded hole 16-2. A pair of first side plates 7 are set on the worktable 1 on both sides of the first conveyor belt 2.
[0024] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows:
[0025] In this utility model, the first telescopic rod 4 and the second telescopic rod 15 are both connected to an external electrical control system via wires. The first conveyor belt 2 and the second conveyor belt 3 are both operated by motor-driven rollers. The above equipment and connection methods are all existing technologies and will not be described in detail here.
[0026] According to the instruction manual Figure 1-6 As can be seen, in use, multiple electric vehicle batteries 20 are conveyed onto the first conveyor belt 2. The rotation of the first conveyor belt 2 moves the multiple batteries 20 toward the second conveyor belt 3 until the battery 20 at the forefront of the conveying direction abuts against the fixed baffle 8. The pushing assembly pushes the battery 20 abutting against the fixed baffle 8 onto the second conveyor belt 3. At this time, the first conveyor belt 2 continues to rotate, causing the batteries 20 on it to move, so that another battery 20 abuts against the fixed baffle 8. The battery 20 pushed onto the second conveyor belt 3 moves on the second conveyor belt 3 under the limiting and guiding action of a pair of limiting components until the battery 20 abuts against the vertical plate 17. At this time, the contact sensor 17-1 transmits a signal to the control system, causing the telescopic end of the second telescopic rod 15 to move vertically downward. The telescopic end of the second telescopic rod 15 drives the connected The horizontal plate 16 moves, causing the fixed plate 18 to move vertically downwards. The fixed plate 18 then moves a pair of test pins 19. The test pins 19 contact the two poles of the battery 20 and are tested through a connected testing device. After the test is completed, the telescopic end of the second telescopic rod 15 retracts, making the height of the vertical plate 17 higher than the height of the battery 20. This allows the second conveyor belt 3 to transport the tested battery 20 outwards. Other batteries 20 are tested in the same way. This invention uses the first conveyor belt 2 to transport multiple batteries 20. The pushing component pushes the battery 20 that abuts against the fixed baffle 8 onto the second conveyor belt 3. After being guided by a pair of limiting components, the battery 20 moves to the position of the testing component. The testing component then tests the battery 20. The testing process is convenient and fast, meets the needs of large-scale testing, and is highly efficient.
[0027] One possible implementation is that when the telescopic end of the first telescopic rod 4 extends, it drives the connected push plate 5 to move. The push plate 5 drives the connected movable baffle 6 to move. When the push plate 5 moves, it abuts against the battery 20, causing the battery 20 to move onto the second conveyor belt 3. During the movement of the battery 20, the movable baffle 6 can block the battery 20 behind it. When the telescopic end of the first telescopic rod 4 retracts to the initial position, under the rotation and conveying of the first conveyor belt 2, the battery 20 behind it can abut against the fixed baffle 8.
[0028] One possible implementation is that when the length of the battery 20 to be tested is different from the length of the push plate 5, the push plate 5 with the same length as the battery 20 to be tested can be replaced. When replacing, the locking block 5-1 on the original push plate 5 is pulled upward from the groove 4-1, and the original push plate 5 drives the connected movable baffle 6 to be removed. The locking block 5-1 on the push plate 5 with the same length as the battery 20 to be tested is inserted into the groove 4-1, so that when the first telescopic rod 4 pushes the battery 20, the movable baffle 6 can effectively limit the next battery 20 to be tested.
[0029] One possible implementation is that when the width of the battery 20 being tested changes, the operator manually rotates the threaded rod 12. Since the threaded rod 12 is threadedly connected to the second side plate 9 and rotatably connected to the first limiting plate 10 (as one method of rotatable connection: the first limiting plate 10 is provided with a connecting ring, the inner ring of which is provided with a bearing, and the inner ring of the bearing is connected to the end of the threaded rod 12), rotating the threaded rod 12 can drive the first limiting plate 10 to move. When the first limiting plate 10 moves, it drives the connected second limiting plate 10-1 to move, so that the distance between the pair of first limiting plates 10 matches the width of the battery 20, allowing the battery 20 to be aligned with the position of a pair of detection pins during testing. After the positions of the pair of first limiting plates 10 and second limiting plates 10-1 are adjusted, the threaded rod 12 is fixed by the shaft locking device 13.
[0030] One possible implementation is that a pair of test pins 19 are installed through the fixed plate 18. By replacing the fixed plate 18 on the horizontal plate 16 and fixing the fixed plate 18 to the horizontal plate 16 with bolts, the position of the pair of test pins 19 on the fixed plate 18 can correspond to the position of the electrode of the battery 20, thus meeting the testing requirements of different models of batteries 20.
[0031] One possible implementation is that a pair of first side plates 7 are provided on the workbench 1 and on both sides of the first conveyor belt 2, and the pair of side plates limit the battery 20 on the first conveyor belt 2.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
