Detailed Implementation

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] As shown in the attached figure, a battery automatic charging and discharging comprehensive tester includes a support 1, a worktable 2 fixed to the support 1, a top plate 3 fixed to the support 1 and located above the worktable 2, on which a moving plate 5 for a negative electrode plate 4, a positive electrode plate 6, an electric push rod 7, a cylinder 8, a cover 9 fixed to the left end of the worktable 2, and a protective cover 10; the left end of the cover 9 is open so that the battery 29 to be tested and the sliding plate 14 can enter from its left end; the lower end of the protective cover 10 is open; the cylinder 8 includes a cylinder body 11 and a piston rod 12, the cylinder body 11 is fixed to the top plate 3, and the piston rod 12 extends downward and its end is fixed to the upper end of the protective cover 10; a linear track 13 is mounted on the worktable 2. A sliding plate 14 is provided with a positioning strip 15; an electric push rod 7 is fixedly connected to the workbench 2, and its output end is located on its left side and fixedly connected to the moving plate 5; a guide sleeve 16 is provided at the left end of the cover 9; a back plate 17 is fixedly connected to the left end of the positive electrode plate 6; a guide rod 18 is fixedly connected to the left end of the back plate 17 and passes through the guide sleeve 16; a limit block 19 is fixedly connected to the left end of the guide rod 18; a spring 20 is fitted on the guide rod 18 and the spring 20 is located between the cover 9 and the back plate 17; a photoelectric switch 21 for detecting the distance to the back plate 17 is fixedly connected to the cover 9; an opening 30 corresponding to the guide sleeve 16 is provided on the cover 9, and an opening 22 corresponding to the electric push rod 7 is also provided on the cover 9.

[0026] As a further improvement to this embodiment, the left end of the sliding plate 14 is provided with a handle 28. After the battery detection is completed, the sliding plate 14 can be easily removed to the right from the range of the cover 9 to facilitate the removal and placement of the battery.

[0027] As a further improvement to this embodiment, a support 23 is provided on the workbench 2, and the electric push rod 7 is fixedly connected to the support 23. The height of the support 23 is reasonably designed according to the negative electrode height of the test battery 29, which can meet the testing of batteries of various specifications within a certain range and avoid frequent replacement of the moving plate 5.

[0028] As a further improvement to this embodiment, the positioning strip 15 includes a positioning part 24 and a connecting part 25 fixedly connected to the positioning part 24; the sliding plate 14 is provided with strip holes 26 arranged in the front-back direction, and the connecting part 25 is connected to the strip holes 26 by bolts 27. This structure allows for quick adjustment of the position of the positioning strip 15 according to the size of different batches of tested batteries.

[0029] As a further improvement in this embodiment, the upper surface of the sliding plate 14 is a rough surface to ensure that the battery under test 29 and the sliding plate 14 do not shift during the test.

[0030] As a further improved technical solution in this embodiment, the cross-section of the guide rod 18 is rectangular, but obviously it can also be a hexahedron or other applicable shapes.

[0031] In use, the battery to be tested 29 can be directly placed on the sliding plate 14, ensuring it is in contact with the positioning strip 15. The positioning strip 15 is pre-positioned according to the specifications of the battery to be tested 29, so that after the battery to be tested 29 is placed on the sliding plate 14, the positive terminal of the battery to be tested 29 is within the contact testing range of the positive plate 6. Then, driven by the electric push rod 7, the moving plate 5 can begin to move to the left. The negative plate 4 on the moving plate 5 will first contact the negative terminal of the battery to be tested 29, ensuring a good electrical connection. Next, the moving plate 5 continues to push the battery to be tested 29 towards the positive plate 6 on the left, until the positive plate 6 contacts the positive terminal of the battery to be tested 29. When the positive plate 6 is pushed by the battery to be tested 29, causing the spring 20 to compress a certain distance, it will trigger the photoelectric switch 21. The photoelectric switch 21 feeds back a signal to the electric push rod 7, and the electric push rod 7 automatically stops running, ensuring that the contact force between the positive and negative terminals of the battery to be tested 29 is moderate, and avoiding damage to the battery to be tested 29 due to excessive pressure. Subsequently, the operator can control cylinder 8 to lower the protective cover 10, preparing for the charge-discharge test of the battery 29 to be tested. After the battery test is completed, the piston rod 12 of cylinder 8 moves in the opposite direction to raise the protective cover 10. Then, the electric push rod 7 can be reversed again to move the moving plate 5 in the opposite direction, that is, to the right. Then, the sliding plate 14 can be manually moved to the right, so that the battery that has completed the test can be easily removed and ready for the next round of testing.

For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
