[0025] The following specific implementation manner will be further described in conjunction with the above-mentioned drawings.

[0026] In the following, various specific details are set forth in order to provide a thorough understanding of the concepts underlying the described embodiments. However, it will be apparent to those skilled in the art that the described embodiments may be practiced without some or all of these specific details. In other cases, well-known processing steps are not specifically described.

[0027] Please refer to Figure 1 , Figure 2 and Figure 5 The accompanying clamping device for battery formation fixture comprises a formation fixture 100, and two parallel guide supports 200 are arranged on both sides of the top of the formation fixture 100, and the guide supports 200 extend to both ends of the top of the formation fixture 100. The accompanying clamping device for battery formation fixture also comprises a plurality of accompanying clamping mechanisms 300, and the number of the accompanying clamping mechanisms 300 is equal to the number of battery clamping positions of the formation fixture 100. Support parts 301 extend outwardly from both sides of the upper end of the accompanying clamping mechanism 300, and the two supporting parts 301 of the accompanying clamping mechanism 300 clamping the battery can be movably supported on the corresponding supporting guide rod 200 along the guide supports 200, and the clamped battery extends into the corresponding battery clamping position; when the formation fixture 100 clamps the battery, the accompanying clamping mechanism 300 moves along the battery clamping direction. Specifically, when the battery is formed, the accompanying clamp mechanism 300 holding the battery puts the battery into the clamping position of the corresponding formation fixture; the supporting parts 301 at both ends of the accompanying clamp mechanism 300 are supported on the corresponding guide support members 200, and when the formation fixture pushes the battery to clamp the battery, the accompanying clamp mechanism 300 also moves along the guide support members 200. In the process of formation, when there is a battery failure, the formation fixture can loosen the battery until the battery can be taken out, so the failed battery can be directly taken out together with the accompanying clamp mechanism 300, and then placed in the battery model to the vacant position, without taking out all the batteries together, simplifying the operation, and other batteries are still in the formation fixture 100, avoiding the battery from cooling down too quickly, ensuring that the battery can be kept at the temperature of formation, and reducing energy consumption.

[0028] Furthermore, in this embodiment, all the accompanying clamping mechanisms 300 are clamped by the overhead crane manipulator accompanying frame clamping mechanism 500, please refer to Figure 4 ; Specifically, in the Chinese patent document, the patent application number is CN2017215629392, two lifting plates 520 are arranged on the hook assembly 510, one lifting plate 520 is connected to the hook part of the hook 511 on the same side, and the other lifting plate 520 is connected to the hook part of the hook 511 on the other side; and the two lifting plates 52 are equidistantly provided with positioning grooves equal to the number of the accompanying clamping mechanism 300, and the distance between the positioning grooves is equal to the distance between each accompanying clamping mechanism 300 after opening; therefore, after the battery formation is completed, the two lifting plates 520 are clamped on both sides of the accompanying clamping mechanism 300, and the support part 301 is stuck in the corresponding positioning groove. Therefore, it is possible to lift the accompanying clamping mechanism 300 on the formation fixture 100 at the same time and at equal distances.

[0029] Further, refer to Figure 2 , Figure 3 and Figure 5The accompanying clamping device for battery formation fixture also includes a support assembly, the number of which is equal to the number of the accompanying clamping mechanism 300; the support assembly is used to support the corresponding accompanying clamping mechanism 300. Specifically, the support assembly includes two supporting sliders 400 arranged opposite to each other, one of the supporting sliders 400 in the same supporting assembly is slidably connected to one of the guide support members 200, and the other supporting slider 400 is slidably connected to the other guide support member 200; specifically, the supporting slider 400 is slidably sleeved on the corresponding guide support member 200. The bottom of the two supporting parts 301 of the accompanying clamping mechanism 300 is provided with a positioning groove 302, and the supporting slider 400 is provided with a positioning boss 401. When the accompanying clamping mechanism 300 is placed on the corresponding supporting assembly, the positioning boss 401 on the corresponding supporting slider 400 extends into the positioning groove 302. In this embodiment, the supporting slider 400 supports and guides the accompanying clamp mechanism 300 , and the positioning boss 401 extends into the positioning groove 302 to position the accompanying clamp mechanism 300 , which can effectively prevent the accompanying clamp mechanism 300 from being misplaced.

[0030] Further, refer to Figure 2 and Figure 5 A slot 4010 is also provided on the top of the boss 401, and a pin 3020 is in the groove 302. When the accompanying clamp mechanism 300 is supported on the corresponding supporting slider 400, the pin 3020 is stuck in the corresponding slot 4010. Therefore, when the layer plate moves, the accompanying clamp mechanism 300 can be driven to slide along the guide support member 200.

[0031] Further, refer to Figure 3 , the bottom of each supporting slider 400 is provided with a lever 402 extending downward, and the two ends of the top of the layer plate of the formation fixture 100 are provided with a lever 110; when the formation fixture 100 pushes the layer plate to release the battery, the lever 110 pushes the corresponding lever 402, so that the accompanying clamp mechanism 300 moves synchronously with the corresponding layer plate. In this embodiment, the lever 110 is fixed to the layer plate, so when the layer plate moves, the accompanying clamp mechanism 300 can be pushed to move forward while clamping the battery, so as to clamp or release the battery; when the layer plate clamps the battery, it is avoided that the accompanying clamp mechanism 300 is dragged by the battery to move along the guide support member 200, so as to protect the battery, and when clamping, the battery can always be in a vertical downward state, so that the force points of all batteries in the formation fixture can be guaranteed to be in the center of the battery, thereby ensuring the quality of battery formation.

[0032] Further, refer to Figure 3, the two ends of the top of the fixed layer of the formation fixture 100 are provided with limit members 120, and the limit members 120 are provided with limit holes 121, and the lever 402 at the bottom of the supporting slider 400 at the fixed end of the limit members 120 extends into the limit holes 121. In this embodiment, when the formation fixture 100 is opened to release the battery, the battery located at the clamping position of the fixed layer of the formation fixture 100 is limited, so that the overhead travelling crane manipulator can take out all the batteries together; and the limit members 120 are provided at both ends of the top of the fixed layer to limit the position, so that when the formation fixture 100 opens the battery, the distance between the accompanying clamp mechanisms 300 can be guaranteed to be equal.

[0033] Further, refer to Figure 3 A connecting member 403 is further provided between adjacent supporting slide blocks 400 on the same guide support member 200 , and the connecting member 403 is used for opening adjacent accompanying clamp mechanisms 300 at equal distances.

[0034] Furthermore, one end of the connecting member 403 is connected to one of the supporting sliders 400 , and the other end is provided with a waist-shaped hole, and a connecting pin passes through the waist-shaped hole to connect to another supporting slider 400 .

[0035] Further, refer to Figure 2 and Figure 3 The side wall of the toggle member 110 is provided with a toggle groove 111 with an opening toward the fixed layer plate of the formation fixture, and the toggle rod 402 extends into the corresponding toggle groove 111, and the groove depth of the toggle groove 111 is greater than the diameter of the toggle rod 402. In this embodiment, when the formation fixture 100 clamps the battery, the bottom wall of the toggle groove 111 abuts against the toggle rod 402, so the toggle member 110 in contact with the toggle rod 402 pushes the accompanying clamp mechanism 300 to move, so that the battery can move with the layer plate of the formation fixture 100, so as to clamp the battery. And because the groove depth of the toggle groove 111 is greater than the diameter of the toggle rod 402, when the battery is clamped by the layer plate, the toggle rod 402 can move in the toggle groove 111 in the clamping direction, so as to prevent the toggle member 110 from interfering with the clamping of the battery.

[0036] Furthermore, when the formation fixture 100 is opened, since the toggle slot 111 is an open slot, the connecting member 403 limits the support slider 400, ensuring that the support slider 400 can be opened equidistantly.

[0037] Further, refer to Figure 2 and Figure 3, the guide support member 200 is a support guide rod; both ends of the guide support rod 200 are provided with an adjustment mechanism 210. The adjustment mechanism 210 includes an adjustment seat 211 and an adjustment screw 212. The adjustment seat 211 is fixedly connected to the top of the formation fixture 100, and the adjustment seat 211 is provided with an adjustment slot, the end of the support guide rod 200 extends into the adjustment slot, and the adjustment screw 212 extends into the adjustment slot from the upper end of the adjustment seat, and the adjustment screw 212 is threadedly connected to the support guide rod 200 and rotatably connected to the adjustment seat 211. Therefore, the height position of the support guide rod 200 can be adjusted by adjusting the screw 212 to adjust the height of the accompanying clamp mechanism 300 set on the support guide rod 200, thereby adjusting the force center of the battery to adapt to the formation of batteries of different sizes.

[0038] Further, refer to Figure 5 and Figure 6 The portable clamp mechanism 300 includes a support plate 310 and a clamping mechanism 320 disposed on the support plate 310; the support portion 301 is located at both ends of the support plate 310, and both ends of the support plate 310 are respectively supported on the corresponding support guide rods 200. In this embodiment, the battery is clamped by the clamping mechanism 320.

[0039] Further, refer to Figure 5 and Figure 6 The clamping mechanism 320 includes a connecting block 321, a pressure rod 322, a compression spring 323 and a clamping claw 324; the connecting block 321 is arranged on the supporting plate 310, and a guide hole (not shown in the drawings) is provided on the connecting block 321, and the pressure rod 322 can slide through the guide hole; a limiting portion 325 is provided at the top of the pressure rod 322, and a connecting portion 326 is provided at the bottom. The compression spring 323 is sleeved on the upper end of the pressure rod 322, the upper end of the compression spring 323 abuts against the limiting portion 325, and the lower end abuts against the connecting block 321; mounting portions 327 extend downwardly from both sides of the connecting block 321, and the two clamping jaws 324 are relatively pivoted between the two mounting portions 327, and an extension portion 328 is provided outwardly at the upper end of the clamping jaw 324, and a connecting rod 329 is provided between the extension portion 328 and the connecting portion 326. The pressure rod 322 is pressed downward to overcome the elastic force of the extension spring 323, and the two clamping jaws 324 open.

[0040] Further, refer to Figure 5 to Figure 7The support plate 310 is provided with a slide groove, the connecting block 321 is slidably arranged in the slide groove, the two side walls of the slide groove are provided with rolling grooves, and the side walls of the mounting portion 327 are provided with rollers extending into the corresponding rolling grooves; the rollers are arranged in the rolling grooves to support the connecting block 321. A self-locking mechanism 330 is provided on one side of the connecting block 321, and the self-locking mechanism 330 locks the clamping mechanism 320 in the slide groove. In this embodiment, the position of the clamping mechanism 320 can be adjusted, so as to ensure that after clamping batteries of different sizes and placing them in the formation fixture 100, the center of the battery and the output center of the formation fixture 100 are on the same straight line.

[0041] Further, refer to Figure 5 to Figure 7 The self-locking mechanism 330 includes a rack 331 disposed on the support plate 310, an extension support portion 332 disposed on one side of the connection block 321, two guide rods 333 slidably penetrating the extension support portion 332, a self-locking plate 334 connected to the upper ends of the two guide rods 333, and a second compression spring 335 sleeved on the guide rods 333; a second limiting portion is disposed at the bottom of the guide rod 333, and a side wall of the self-locking plate 334 is disposed with straight teeth meshing with the rack 331.
