[0001] The utility model relates to the technical field of lithium ion battery test fixtures, in particular to an opening clamp device for a lithium battery test capacity distribution cabinet. Background Art
[0002] Capacity separation is one of the key processes for lithium-ion batteries. Testing is performed to understand whether the actual capacity and performance of the battery meet the design requirements. However, in mass production, personnel operating the upper and lower cabinets need to use a single clip to open the clamp, which is inefficient and difficult to operate. It is labor-intensive and can easily cause battery short circuits. At this time, an opening clamp device is needed.
[0003] Traditional clamping devices can only open and close multiple clamps at the same time. However, when placing lithium batteries during use, the clamps with lithium batteries cannot be closed in time and can only be closed together after all lithium batteries are placed. As a result, the previously placed lithium batteries may be knocked off when other lithium batteries are placed later, which can easily cause the lithium batteries to be damaged and cannot be tested and used. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a clamping device for a lithium battery test capacity distribution cabinet, so as to solve the problem that the clamping body containing lithium batteries in the prior art cannot be closed in time, resulting in the possibility of knocking off the previously placed lithium batteries when other lithium batteries are subsequently placed, which easily causes the lithium batteries to be damaged and unable to be tested and used.
[0005] In view of this, the utility model provides a clamping device for a lithium battery test capacity distribution cabinet, comprising a fixed plate, a mounting frame is fixedly mounted on the top of the fixed plate, and a clamping moving mechanism is arranged inside the mounting frame and the fixed plate;
[0006] The clamping and moving mechanism includes a guide rail, a slider and a pressure rod. A plurality of movable grooves are opened inside the fixed plate. The guide rail is fixedly installed inside the movable groove. The slider is slidably connected to the side wall of the guide rail. A clamping body is fixedly installed on the top of the slider. A first spring is installed on the side wall of the guide rail. A sliding groove is opened inside the mounting frame. The pressure rod moves inside the sliding groove.
[0007] Optionally, one end of the first spring is fixedly mounted on the inner wall of the movable groove, and the other end of the first spring is fixedly mounted on one side of the slider.
[0008] Optionally, a groove is provided on the side wall of the clamp body, and the pressure rod matches the groove.
[0009] Optionally, a toggle member is fixedly mounted on one end of the pressure rod.
[0010] Optionally, a clamping mechanism is provided inside the mounting frame.
[0011] Optionally, the clamping mechanism includes a second spring and a clamping block, an installation cavity is opened inside the mounting frame, the installation cavity is located on one side of the sliding groove, the second spring is fixedly installed inside the installation cavity, and the clamping block is fixedly installed at one end of the second spring.
[0012] Optionally, a plurality of slots are provided on the side wall of the pressure rod, and the slots match the block.
[0013] It can be seen from the above technical solutions that the embodiments of the utility model have the following advantages:
[0014] 1. The utility model is a clamping device for a lithium battery test capacity cabinet, which adopts a clamping moving mechanism. After a pressure rod slides from one end to the other end inside a sliding groove, the clamp body can be pressed down to open. At this time, the lithium battery to be fixed can be placed inside the clamp body. When a lithium battery is placed inside the clamp body, the clamp body is pushed to make the slider slide inside the movable groove through a guide rail. At this time, the clamp body will be separated from the pressure rod, so that the clamp body can clamp the lithium battery to avoid the subsequent lithium battery falling and damage.

[0024] The following is a detailed description of an opening device for a lithium battery test capacity distribution cabinet according to an embodiment of the utility model in conjunction with the accompanying drawings.
[0025] Example 1
[0026] For easier understanding, see Figures 1 to 4 The utility model provides an embodiment of a clamping device for a lithium battery test capacity cabinet, comprising a fixed plate 1, a mounting frame 2 is fixedly mounted on the top of the fixed plate 1, and a clamping moving mechanism is arranged inside the mounting frame 2 and the fixed plate 1;
[0027] The clamping and moving mechanism includes a guide rail 8, a slider 9 and a pressure rod 4. A plurality of movable grooves 7 are opened inside the fixed plate 1. The guide rail 8 is fixedly installed inside the movable groove 7. The slider 9 is slidably connected to the side wall of the guide rail 8. A clamping body 6 is fixedly installed on the top of the slider 9. A first spring 10 is installed on the side wall of the guide rail 8. A sliding groove 3 is opened inside the mounting frame 2, and the pressure rod 4 moves inside the sliding groove 3.
[0028] It should be noted that, by setting the pressure rod 4, the clamp 6 can be pressed down and opened after the pressure rod 4 slides from one end to the other end inside the sliding groove 3. At this time, the lithium battery to be fixed can be placed inside the clamp 6. When the lithium battery is placed inside the clamp 6, the clamp 6 is pushed to make the slider 9 slide inside the movable groove 7 through the guide rail 8. At this time, the clamp 6 will be separated from the pressure rod 4, so that the clamp 6 can clamp the lithium battery to prevent the lithium battery from falling and being damaged subsequently. By setting the first spring 10, the slider 9 can be pushed to one side, so that the slider 9 can be reset after the subsequent pressure rod 4 is raised, so that the pressure rod 4 can press down again to open the clamp 6.
[0029] In some embodiments, Figure 3 As shown, one end of the first spring 10 is fixedly mounted on the inner wall of the movable groove 7 , and the other end of the first spring 10 is fixedly mounted on one side of the slider 9 .
[0030] It should be noted that the slider 9 can be pushed to one side by providing the first spring 10 .
[0031] In some embodiments, Figure 1 As shown, a groove is provided on the side wall of the clamp body 6, the pressure rod 4 matches the groove, and a toggle member 5 is fixedly mounted on one end of the pressure rod 4.
[0032] It should be noted that, by providing the groove, the pressure rod 4 can be more easily pressed down the clamping body 6 , and by providing the toggle member 5 , the pressure rod 4 can be more easily toggled.
[0033] Example 2
[0034] In some embodiments, Figure 4 As shown, a clamping mechanism is arranged inside the mounting frame 2, and the clamping mechanism includes a second spring 13 and a clamping block 14. A mounting cavity 12 is opened inside the mounting frame 2, and the mounting cavity 12 is located on one side of the sliding groove 3. The second spring 13 is fixedly installed inside the mounting cavity 12, and the clamping block 14 is fixedly installed at one end of the second spring 13. A plurality of clamping grooves 11 are opened on the side wall of the pressure rod 4, and the clamping grooves 11 match the clamping blocks 14.
[0035] It should be noted that, by opening a slot 11 on the side wall of the pressure rod 4, when the pressure rod 4 moves downward to press the clamp body 6 to open, the second spring 13 can push the block 14 into the slot 11 to fix the pressure rod 4, prevent the pressure rod 4 from being pushed up by the clamp body 6, and ensure the stability of opening the clamp. The block 14 and the slot 11 are a triangular structure, and the block 14 can be separated from the slot 11 by pushing the pressure rod 4.
[0036] Working principle: When in use, the pressure rod 4 is slid from one end to the other end inside the sliding groove 3 through the toggle piece 5. When the pressure rod 4 moves to the other end of the sliding groove 3, the second spring 13 pushes the card block 14 to be clamped in the card slot 11 to fix the pressure rod 4 to prevent the pressure rod 4 from being pushed up by the clamp body 6. At this time, the clamp body 6 is in an open state, and the lithium battery to be fixed can be placed inside the clamp body 6. When a lithium battery is placed inside the clamp body 6, the clamp body 6 is pushed to make the slider 9 slide inside the movable groove 7 through the guide rail 8. At this time, the clamp body 6 will be separated from the pressure rod 4, so that the clamp body 6 can clamp the lithium battery.
