[0002] A battery cell refers to a single electrochemical cell containing positive and negative electrodes. During the charge and discharge process of lithium-ion batteries, various side reactions will cause the battery cells to produce gas and expand, which in turn affects the performance of the battery cells. After the internal repair of the battery cell is completed, the outside of the battery cell needs to be squeezed. Currently, a battery cell pressing machine is mostly used for this purpose. In actual use, it has the advantages of simple operation, stable structure and good pressing effect.

[0003] The prior art discloses a cell stacking and pressing device for a cell module with publication number: CN219067054U, comprising a fixing plate, a first fixing frame, a first supporting plate, a second supporting plate, a second fixing frame, a cylinder, a through hole, a pressing plate, a first guide groove, a first guide rod, a second guide groove, a second guide rod, a stopper and a rubber block. When the device is needed, the expanded battery is first placed inside the first fixing frame, the first supporting plate, the second supporting plate and the second fixing frame, and then the cylinder can be controlled to start, so that the cylinder output end moves to the left, and the cylinder output end drives the pressing plate to move to the left, so that the pressing plate squeezes the battery to the left. When the battery pack returns to its normal shape, the left side of the pressing plate contacts the right side of the stopper, and the cylinder output end can be controlled to move to the right, driving the pressing plate to move back to the initial position, and then the cylinder can be closed, and finally the battery pack is taken out.

[0004] The above utility model controls the pushing of the pressure plate by the extension and retraction of the cylinder to complete the core pressing and reshaping work of the battery pack. This operation cannot be carried out continuously. It is necessary to take out the battery pack that has been reshaped and then put in a new battery pack before continuing the core pressing and reshaping work. This operation will consume a certain amount of time, thereby affecting the core pressing efficiency of this utility model.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

When the pressure on the left group of pressure sensors reaches the preset value, it will send a signal to the controller, and the controller will make the output end of the forward and reverse motor rotate counterclockwise. The rotating wire lever of the needle can push the screw sleeve to move right, and the screw sleeve drives the moving rod to move right through the moving block and the connecting plate. The moving rod that moves right can push a group of push plates. Finally, the battery pack between the two groups of push plates on the right will be pressed together, and the battery pack will gradually return to its normal shape. At the same time, the operator can replace the battery pack inside a group of installation boxes on the left. When the pressure borne by a group of pressure sensors on the right reaches the preset value, a signal will be sent to the controller to make the output end of the forward and reverse motor rotate clockwise. Repeat the above operation, and multiple battery packs can be pressed. The guide rod ensures the stability of the lateral movement of the moving block. Four groups of limit slots and eight groups of T-shaped slides can ensure the stability of the lateral movement of the four groups of push plates. Through the set installation box, the core pressing work of multiple battery packs can be completed without stopping the core pressing work, thereby improving the working efficiency of the battery core pressing machine.

[0019] (2) The utility model adopts a cleaning box. Before actually pressing multiple battery packs, the operator first manually passes a battery pack through a set of installation slots.

[0036] Working principle:

[0037] When the battery core pressing machine is actually used, the operator manually puts the battery pack into the left group of installation boxes 2, and then connects the forward and reverse motor 14 to the power supply. The output end of the forward and reverse motor 14 can drive the wire lever 10 to rotate clockwise. Since the wire lever 10 and the screw sleeve 11 threads cooperate with each other, the clockwise rotating wire lever 10 can push the screw sleeve 11 to move left, and the screw sleeve 11 drives the moving rod 5 to move left through the moving block 12 and the connecting plate 15. The moving rod 5 that moves left can push a group of push plates 7. Finally, the battery pack between the two groups of push plates 7 on the left will be pressed together, and the battery pack will gradually return to its normal state. When the pressure on the left side pressure sensor 9 reaches the preset value, a signal is sent to the controller, which makes the output end of the forward and reverse motor 14 rotate counterclockwise. The counterclockwise rotating wire lever 10 can push the screw sleeve 11 to move right. The screw sleeve 11 drives the moving rod 5 to move right through the moving block 12 and the connecting plate 15. The moving rod 5 that moves right can push a group of push plates 7. Finally, the battery pack between the two groups of push plates 7 on the right side will be pressed together, and the battery pack will gradually return to its normal state. At the same time, the operator can replace the left side. A battery pack inside a mounting box 2, when the pressure of a group of pressure sensors 9 on the right side reaches a preset value, a signal will be sent to the controller to make the output end of the forward and reverse motor 14 rotate clockwise, and the above operation can be repeated to perform core pressing work on multiple battery packs. The guide rod 13 ensures the stability of the lateral movement of the moving block 12, and the four groups of limit slots 6 and eight groups of T-shaped slide plates 8 can ensure the stability of the lateral movement of the four groups of push plates 7. Through the setting of the mounting box 2, the core pressing work of multiple battery packs can be completed without stopping the core pressing work, thereby improving the working efficiency of the battery core pressing machine. At the same time, multiple battery packs can be pressed in practice Before that, the operator manually passes a battery pack through a set of installation slots 18. According to the above operation, it can be known that when the power is turned on and the controller is coordinated, the output end of the forward and reverse motor 14 can drive the wire lever 10 to rotate clockwise and counterclockwise, and the wire lever 10 can drive the extension shaft 16 to move synchronously. The extension shaft 16 can clean the surface of the battery pack through the brush 17. When the cleaning is completed, the core pressing work can be carried out. The cleaning box 4 is set up to remove impurities on the surface of the battery pack in advance to avoid the situation where the battery pack is crushed by impurities during the core pressing process, which brings a guarantee for the protection of the battery pack of the battery core pressing machine.
