[0025] In a specific implementation manner, the module stacking auxiliary tooling includes a module positioning mechanism 2, a module clamping mechanism 4, and a fixture table 1. A battery - cell module stacking space is formed between the module positioning mechanism 2 and the module clamping mechanism 4. The module positioning mechanism 2 is fixed on the fixture table 1. The module clamping mechanism 4 includes a clamping fixed part and a clamping movable part. The clamping fixed part is fixed on the fixture table 1. The clamping movable part is movably connected to the clamping fixed part and is used to move towards the module positioning mechanism 2 to perform a clamping operation on the battery - cell module in the battery - cell module stacking space, or move away from the module positioning mechanism 2 to release the battery - cell module stacking space.

[0028] By arranging the first end plate and the second end plate, it can be directly matched with the size and type of the cell module to be stacked, so that during the stacking process of cell modules of different sizes and types, only different-sized first end plates and second end plates need to be replaced to achieve, greatly reducing the applicability to different cell modules.

[0029] In this application, the sizes and materials of the first end plate and the second end plate are not limited, as long as they do not form an electrical circuit loop with the cell module.

[0030] In order to further ensure insulation and reduce the material restrictions on the end plates, in one embodiment, the module stacking auxiliary tooling further includes an insulating layer arranged on the surfaces of the first end plate and the second end plate, which is used to insulate between the cell module and the first end plate and the second end plate.

[0035] This application does not limit the structure of the module length direction positioning mechanism 3 and its connection method with the fixture table 1.

[0036] Generally, the bottom of the module length direction positioning mechanism 3 is bolted or clamped to the fixture table 1.

[0037] In a later embodiment of this application, in order to further improve the safety of the stacking between the end plate and the battery cell, the module stacking auxiliary tooling further includes an end plate positioning pin 201 provided in the module positioning mechanism for positioning the second end plate, which is used to ensure that the distance between the bottom of the second end plate and the bottom of the nearest battery cell module is greater than the minimum safety distance.

[0039] In order to facilitate the installation of the end plate positioning pin 201, the pin mounting block 202 is provided, and the end plate positioning pin 201 is installed on the pin mounting block 202, improving the convenience of installation. The pin mounting block is clamped or bolted to the positioning mounting seat of the module positioning structure, or connected in other ways.

[0040] In this application, the type of the pin mounting block 202 is not limited. Generally, a POM pin mounting block is used. Making the pin mounting block with POM can avoid the situation of short - circuit sparking of the battery cell caused by human factors and improve the safety of use.

The main mounting seat 411 passes through the spacer block 412 and is fixedly connected to the fixture table 1. The ball screw 408 sleeve passes through the vertical part of the main mounting seat 411 and is fixedly connected to the vertical part of the main mounting seat 411. The ball screw 408 is arranged in the ball screw sleeve 409.

The sensor mounting seat 404 is used to mount the pressure sensor 405. The module clamping mechanism 4 drives the forward and backward movement of the clamping pin 401 through the rotation of the handwheel 412, and then drives the movement of the first end plate.

[0043] By setting the handwheel 412 to move forward and backward, setting the ball screw 408 to push the relevant components, changing the rotation into the power of forward or backward movement. At the same time, the purpose of setting the clamping pin mounting block 402 and the clamping pin 401 is the same as that of the pin mounting block and the pin of the above - mentioned module positioning structure. On the one hand, it is convenient to position the first end plate, and on the other hand, it is also convenient to replace the first end plate to achieve the adaptability to different first end plates.

[0044] The module clamping mechanism 4 mainly squeezes the battery cell module by pushing the movable end plate. When the battery cell module is squeezed to an appropriate length, the value of the pressure sensor is recorded, and then the module is sleeved with a steel belt within the range of the pressure values recorded for the subsequent same module.

[0047] By providing a walking structure at the bottom of the support frame and allowing the fixture table 1 to move its position through the walking structure, it is convenient to move the position arbitrarily during use and reduces the limitation on the position.

[0048] In this application, the structures of the support frame and the walking structure are not limited.

[0049] The walking structure includes but is not limited to a crawler walking structure or a universal wheel walking structure, and can also be other types of walking mechanisms.

[0050] In order to further improve the management efficiency, in one embodiment, the module stacking auxiliary tooling further includes a display and a reminder connected to the pressure sensor. The display is used to display the pressure value detected by the pressure sensor, and the reminder is used to output a reminder signal after detecting that the pressure value is greater than or equal to the pressure threshold.

[0051] By providing a display to display the pressure value detected by the pressure sensor in real time, the staff can determine the current extrusion state. By providing a reminder to output a reminder signal after detecting that the pressure value is greater than or equal to the pressure threshold, the optimal steel belt sleeving timing can be obtained and the operation efficiency can be improved.

[0052] In one embodiment, the module stacking auxiliary tooling includes: a trolley frame, an end plate positioning mechanism, a module length direction positioning mechanism 3, and a module clamping mechanism 4. The trolley frame serves as the fixture table 1 and carries other components. The stacking method of this tooling trolley is as follows:

[0053] First, place the end plate (with insulating paper already pasted) on the end plate positioning mechanism, and position the end plate through the pin. Place another end plate on the module clamping mechanism 4 and position it through the pin. Place the battery cells with buffer pads pasted on them in sequence on the stacking tooling cart base plate, and make them lean against the module lengthwise positioning mechanism 3 to position the module in the lengthwise direction. Rotate the handwheel of the module clamping mechanism 4 so that its end plate pushes the battery cells towards the fixed end plate positioning mechanism. The module clamping mechanism 4 is equipped with a pressure sensor. When the module is squeezed to a state where the steel belt is convenient to be sleeved and will not fall off, record the pressure value of the pressure sensor. After the same type of module production is squeezed to the recorded pressure value, sleeve the steel belt. Using this tooling cart for small-batch production can greatly improve the product production efficiency.

[0054] During the operation process, the lower steel belt is pre-buried under the stacking plate in advance, the upper steel belt has no obstacle to falling, and after the steel belt is sleeved, loosen the handwheel, and the battery cells will tension the steel belt.

[0055] In summary, for the module stacking auxiliary tooling provided in the embodiment of the present application, a battery cell module stacking space is formed between the module positioning mechanism and the module clamping mechanism. The module positioning mechanism is fixed on the fixture table, its clamping and fixing part is fixed on the fixture table, and its clamping and moving part is movably connected to the clamping and fixing part, and is used to move towards the module positioning mechanism to realize the clamping operation or release operation of the battery cell module in the battery cell module stacking space.
