At this time, the top and bottom of the casing are sucked, and then by adjusting the first servo electric cylinder 13, the casing opening can be opened. This step can adjust the shape of the casing opening of the square battery casing, making it smoother for the cell to enter the casing, and the casing opening will not cause abrasion to the cell, thereby reducing damage to the cell.

[0024] As Figure 1 、 Figure 3As shown in the figure, a chute 2 is fixedly connected to the top of the machine table 1; a second servo cylinder 21 is fixedly connected to the top of the machine table 1; a slider 22 is fixedly connected to the end of the telescopic rod of the second servo cylinder 21. During operation, the battery cell is placed on the top of the chute 2, and then the second servo cylinder 21 is started to push the cell into the battery case. This step can conveniently push the cell into the battery case in the horizontal direction, preventing damage caused by the cell tilting and rubbing against the case opening.

[0025] As Figure 1 , Figure 4 shown in the figure, a first conveyor assembly 3 is fixedly connected to the top of the machine table 1; a first servo motor 31 is fixedly connected to the top of the machine table 1; one of the rollers of the first conveyor assembly 3 is fixedly connected to the output end of the first servo motor 31; a third servo cylinder 32 is fixedly connected to the top of the machine table 1; two oppositely arranged receiving plates 33 are fixedly connected to the inner side wall of the machine table 1. During operation, the first conveyor assembly 3 can be used in cooperation with other equipment to complete the input of the case. Then, when the case reaches the specified position, the third servo cylinder 32 is started to push the case into the hole in the middle of the machine table 1, so that the case falls on the top of the receiving plates 33 to complete the positioning of the case, and then subsequent operations such as expanding the case opening are carried out. This step can complete the automatic feeding of the battery case, reduce manual operation, and save human resources.

[0026] As Figure 1 , Figure 4 shown in the figure, a second conveyor assembly 4 is fixedly connected to the top of the machine table 1; a second servo motor 41 is fixedly connected to the top of the machine table 1; one of the rollers of the second conveyor assembly 4 is fixedly connected to the output end of the second servo motor 41.

This step can buffer the cell when it is inserted into the case, reducing the damage caused by the contact between the end of the cell and the side wall of the case.

[0028] As Figure 1 ,Figure 4 As shown, a plurality of limiting plates 6 are fixedly connected to the top of the machine table 1; the plurality of limiting plates 6 are arranged along both sides of the first conveying assembly 3 and the second conveying assembly 4; during operation, when the product moves on the first conveying assembly 3 and the second conveying assembly 4, it will be blocked by the limiting plates 6 and cannot fall off. This step can reduce the risk of the product falling off during movement on the conveying device.

This step can reduce the damage to the end of the battery cell caused by extrusion.

[0030] During operation, place the battery housing in the groove in the middle of the machine table 1, start the first servo cylinders 13 at the top and bottom of the housing so that it is clamped in the middle, then start the electric push rod 17 to drive the piston of the air cylinder 16 to move, and evacuate the air inside the rubber suction cup 14 in contact with the housing through the hose 15 to form a negative pressure. At this time, the top and bottom of the housing are sucked, and then by adjusting the first servo cylinder 13, the housing opening can be opened. This step can adjust the shape of the housing opening of the square battery housing, making it smoother for the battery cell to enter the housing, and the housing opening will not cause abrasion to the battery cell, thereby reducing damage to the battery cell. Place the battery cell on the top of the chute 2, and then start the second servo cylinder 21 to push the battery cell into the battery housing. This step can conveniently push the battery cell into the battery housing in the horizontal direction, preventing damage caused by the battery cell tilting and rubbing against the housing opening. The first conveying component 3 can be used in cooperation with other equipment to complete the input of the housing. Then, when the housing reaches the specified position, start the third servo cylinder 32 to push the housing into the hole in the middle of the machine table 1, so that the housing falls on the top of the receiving plate 33 to complete the positioning of the housing, and then perform subsequent operations such as expanding the housing opening. This step can complete the automatic feeding of the battery housing, reduce manual operation, and save human resources. After the battery cell is inserted into the housing, air is re-injected into the rubber suction cups 14 at the top and bottom of the housing, and then the first servo cylinder 13 contracts to the specified position. Then start the third servo cylinder 32 to push the product to the top of the second conveying component 4, and transfer the product through the coordinated operation of the second conveying component 4 and other equipment. This step can complete the automatic output of the product after the battery cell is inserted into the housing, reduce manual operation, and save human resources. When the battery cell is pushed into the housing by the slider 22, a gradually increasing force will be provided by the spring 51 to the slider 22, so that the battery cell is buffered when it is pushed into the housing, and the pushing speed gradually slows down, reducing the force between the end of the battery cell and the side wall of the housing when they come into contact. This step can buffer the battery cell when it enters the housing and reduce the damage caused by the contact between the end of the battery cell and the side wall of the housing. When the product moves on the first conveying component 3 and the second conveying component 4, it will not fall off due to the blockage of the limiting plate 6. This step can reduce the risk of the product falling off when moving on the conveying device.
