[0002] The battery module boxing process refers to placing the battery modules that have been assembled, tested and meet quality standards safely and orderly into a dedicated battery box to form a final battery pack to provide energy for electric vehicles, energy storage systems or other equipment.

[0003] The existing battery module boxing generally includes the following steps: using an automated robotic arm or conveyor system to automatically move the tested battery modules from the end of the production line or the temporary storage area to the boxing station; after arriving at the boxing station, the module is positioned; after the module is correctly positioned, the automated or semi-automated tooling starts working, using screws, buckles, locking belts or other fixing devices to firmly fix the module in the box; after the module is fixed in place, electrical connections and cooling system installation are also performed. After completing the above steps, the box is sealed and tested.

[0004] Existing module positioning devices, such as a battery box module positioning pin, structure and method disclosed in publication number "CN116598697A", ​​set positioning pins on both sides of the module and reserve positioning holes inside the box body, but this operation is cumbersome and will affect production efficiency. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that the module is put into the box through the cooperation of the positioning pin and the positioning hole reserved inside the box, which requires the positioning hole to be reserved in advance inside the box, the operation is cumbersome, and the production efficiency is affected. A tooling for module placement and a battery assembly system are provided.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A tool for placing modules into a box, comprising a bottom plate and:

[0008] A clamping jaw, wherein the clamping jaw as a whole can only approach or move away from the bottom plate, and the clamping jaw can be used to position the box and the module;

[0009] A pressing assembly, the pressing assembly being arranged above the clamping area of ​​the clamping jaws, and the pressing assembly being capable of moving in a direction perpendicular to the plane where the bottom plate is located;

[0010] A fixing component is used to fix the box.

[0011] Because the clamp can only move in the direction of approaching or moving away from the bottom plate, the box is fixed by the clamp, and the module is pressed into the box after being moved and positioned by the clamp. The axis of the box and the module coincide, so that the module is centered in the box, meeting the design requirements of the battery. Compared with the prior art, which presets positioning holes on the bottom plate of the box, this device does not need to set positioning holes, and only needs to operate the clamp and the pressing assembly to assemble the module into the inside of the box, which is convenient for improving production efficiency.

[0012] As a preferred solution of the utility model, the pressing assembly includes a connecting block and a pressure applying device, the bottom surface of the connecting block can be detachably connected to the module pressure maintaining block or the box pressure maintaining block, and the pressure applying device is used to apply constant pressure.

[0013] Battery module pressure maintenance usually refers to a pressure maintenance test or process operation performed during or after the assembly of the battery module. Its purpose is to ensure that the battery cells or related components inside the module achieve ideal structural stability, electrical connection performance and safety status under specific pressure conditions. The size of the module pressure maintenance block is adapted to the size of the module to be placed in the box. The battery box pressure maintenance test is an important part of ensuring the integrity and safety of battery packaging. The main purpose is to verify the sealing performance of the battery box to prevent the external environment such as moisture and dust from entering the battery, and also to avoid the leakage of gas generated during the use of the battery, causing safety hazards. The module pressure maintenance block or the box pressure maintenance block can be replaced as needed. Compared with the existing device, after the module is placed in the box, the box needs to be moved to a dedicated module pressure maintenance device for module pressure maintenance. This device can maintain pressure immediately after the module is placed in the box without moving, which is conducive to improving battery assembly efficiency.

[0014] As a preferred solution of the utility model, the pressure applying device is connected to the connecting block via a floating joint.

[0015] The floating joint can absorb vibration, compensate displacement and improve connection stability, and is suitable for module entry.

[0016] As a preferred solution of the utility model, the pressure applying device includes a cylinder, a hydraulic cylinder, a spring loading device, an electromagnet or a weight.

[0017] As a preferred solution of the utility model, it also includes a door-type frame, the crossbeam of the door-type frame is used to connect the pressing assembly, and the opening of the clamping claw faces the hole of the door-type frame.

[0018] The door-shaped frame is provided, which is stable and has strong applicability. The opening direction of the clamping jaws faces the opening of the door-shaped frame, which will not limit the size of the side of the box body perpendicular to the plane where the door-shaped frame is located.

[0019] As a preferred solution of the utility model, a limiting column is provided at the lower part of the pressing assembly, and the limiting column is used to limit the minimum height of the pressing assembly.

[0020] Set limit posts to prevent the downward pressure component from pressing down too high and causing damage to the module.

[0021] As a preferred solution of the present invention, the fixing assembly includes a plurality of fixing blocks, and the distance between two adjacent fixing blocks can be adjusted.

[0022] The distance between two adjacent fixing blocks is adjusted according to the size of the box.

[0023] As a preferred solution of the utility model, the clamp comprises two opposite clamping members, the clamp is provided with a moving track, at least one of the clamps can move along the moving track, and the clamp opens and closes by the movement of the clamp along the moving track.

[0024] The clamping jaws are provided with moving tracks, and compared with the clamping jaws provided with rotating shafts, the operating accuracy is improved, and it is suitable for the assembly of modules.

[0025] As a preferred solution of the present utility model, the pressing assembly can move along a first guide rail, and the first guide rail is perpendicular to the plane where the bottom plate is located.

[0026] A battery assembly system includes a tool for placing modules into boxes as described above.

[0027] By adopting the above-mentioned module boxing tooling, the boxing accuracy can be guaranteed without affecting the battery assembly efficiency. And after the module is assembled into the box, there is no need to move the box to the dedicated module pressure-maintaining device. This device can maintain pressure immediately after the module is put into the box without moving, which is conducive to improving the battery assembly efficiency.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

Since the clamp can only move in the direction of approaching or moving away from the bottom plate, the box is fixed in position by the clamp, and the module is pressed into the box after being moved and positioned by the clamp. The axis of the box and the module coincide, so that the module is placed in the center of the box, meeting the design requirements of the battery. Compared with the prior art, which presets positioning holes on the bottom plate of the box, this device does not need to set positioning holes. It only needs to operate the clamp and the pressing assembly to assemble the module into the inside of the box, which is convenient for improving production efficiency. This device solves the problem that the prior art requires the positioning pins to match the positioning holes reserved inside the box, and the positioning holes need to be reserved in advance inside the box, which is cumbersome to operate and affects production efficiency.

[0030] 2. A battery assembly system can ensure the accuracy of the box body without affecting the battery assembly efficiency. After the module is assembled into the box, there is no need to move the box body to a dedicated module pressure-maintaining device. This device can maintain pressure immediately after the module is put into the box without moving, which is conducive to improving the battery assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] like Figure 1-Figure 6 As shown, a tooling for placing modules into a box comprises a base plate 3, and also comprises: a clamping jaw 102, the clamping jaw 102 as a whole can only approach or move away from the base plate 3, the clamping jaw 102 can be used to position the box and the module; a pressing assembly, the pressing assembly is arranged above the clamping area of ​​the clamping jaw 102, the pressing assembly can move in a direction perpendicular to the plane where the base plate 3 is located; a fixing assembly, the fixing assembly is used to fix the box.

[0046] like Figure 1 and Figure 2As shown, in this embodiment, the plane where the two clamping parts of the clamping jaw 102 are located is parallel to the plane where the bottom plate 3 is located, and the moving direction of the clamping jaw 102 as a whole is perpendicular to the plane where the bottom plate 3 is located, and the clamping jaw 102 as a whole can only move in this direction. However, in actual operation, the moving direction of the clamping jaw 102 as a whole can be offset, as long as the clamping jaw 102 as a whole can only approach or move away from the bottom plate 3 in one direction.

[0047] like Figure 3 As shown, in this embodiment, the clamping jaw 102 is driven by a positioning cylinder 101, and the positioning cylinder 101 is arranged on one side of the base plate 3. The clamping jaw 102 comprises two "L"-shaped clamping members. The clamping jaw 102 is provided with a moving track (not shown in the figure), and the length direction of the moving track is parallel to the opening and closing direction of the clamping jaw 102, and the clamping jaw 102 is opened and closed by moving its clamping members along the moving track respectively. The clamping jaw 102 is provided with a moving track. Compared with the clamping jaw 102 with a rotating shaft, the operating accuracy is improved, which is suitable for the assembly of the module. The clamping jaw 102 can approach or move away from the base plate 3 along the second guide rail 107. The axis of the second guide rail 107 is perpendicular to the plane where the base plate 3 is located.

Use a fixing assembly to fix the position of the box on the bottom plate 3 to avoid the position of the box being offset when the module is pressed down, which affects the quality of the battery. Move the jaws 102 upward so that the position of the jaws 102 is higher than the top of the box. Place the module on the top of the box and install the module pressure-maintaining block 206 to the predetermined position. Open and close the jaws 102 so that the center line of the module is opposite to the center line of the jaws 102, adjust the required air pressure of the pressure regulating valve 208, turn the manual valve 209 to start the pressure-maintaining cylinder 201, so that the module pressure-maintaining block 206 is pressed down, the module is put into the box and the module pressure-maintaining is completed. After the module pressure-maintaining is completed, lift the module pressure-maintaining block 206. The module pressure-maintaining block 206 is replaced with the box pressure-maintaining block 205. After the box is sealed, the box pressure is maintained.
