[0059] The working principle of the present invention:

[0060] The present invention is provided with a feeding component, a transfer component, a deviation rectifying component and a feeding roller component, which can feed and rectify the pole piece coil 1 and then convey it to the composite tablet pressing mechanism for hot pressing treatment with the diaphragm coil 2. The composite tablet pressing mechanism performs secondary hot pressing on the pole piece coil 1 and the diaphragm coil 2 to form a composite sheet. The storage component stores the output composite sheet, and finally matches the cutting efficiency of the cutting mechanism 27 to efficiently output the finished composite sheet, with high working efficiency and good processing effect, meeting the requirements of hot pressing and compounding of large quantities of large-sized pole pieces.

[0061] The feeding component can drive the lifting plate 4 to move up and down through the lifting unit 3. The lifting unit 3 can select lifting structures such as lifting screws and lifting electric cylinders. The lifting plate 4 can place the pole piece coil 1 to be processed. After the lifting plate 4 drives the pole piece coil 1 to rise, the adsorption mechanism can move along the Y-axis direction through the adsorption Y-axis moving mechanism 7, that is Figure 1The direction in which the middle lifting mechanism approaches or moves away from the deviation rectifying platform; multiple connection ends can be arranged at the bottom or both sides of the support plate 5, and a plurality of suction cups 6 are adjustably connected to the multiple connection ends in a detachable manner. The adsorption Z-axis moving mechanism 8 is adjusted to enable the suction cups 6 to descend and fit against the electrode sheet coil 1. The transfer assembly places the electrode sheet coil 1 on the deviation rectifying platform, and the deviation rectifying platform can rectify the electrode sheet coil 1 placed by the adsorption mechanism. The deviation rectifying driving unit 10 can drive the deviation rectifying panel 9 to rotate the electrode sheet coil 1 in the X-axis direction, Y-axis direction, and Z-axis direction, so as to adjust the position of the electrode sheet coil 1. After the electrode sheet coil 1 is rectified, the transfer assembly conveys the rectified electrode sheet coil 1 to the feeding roller assembly. The feeding clamping unit 12 can select the clamping arm, and the feeding clamping unit 12 can move in the Y-axis direction. The distance between every two opposite feeding clamping units 12 can be controlled by the feeding Y-axis moving unit 13, so as to enable each group of feeding clamping units 12 to clamp or release the electrode sheet coil 1; every two opposite feeding clamping units 12 are divided into a group, and multiple groups of feeding clamping units 12 can be arranged; the feeding X-axis moving unit 14 prompts the clamped electrode sheet coil 1 to move towards the pressing roller assembly. The moving speed of the moving end of the feeding X-axis moving unit 14 is faster than the speed of the feeding belt 11. The electrode sheet coil 1 is conveyed between the first upper pressing roller 16 and the first lower pressing roller 17. At this time, the diaphragm coil 2 is also conveyed between the first upper pressing roller 16 and the first lower pressing roller 17. The first upper pressing roller 16 provided with the upper heating element and the first lower pressing roller 17 provided with the lower heating element heat up simultaneously, and the first hot pressing and compounding can be realized to form a composite sheet. The composite sheet is heated between the upper heating plate 22 and the lower heating plate 23 and then continues to be conveyed by the feeding belt 11 to between the second upper pressing roller 18 and the second lower pressing roller 19 to complete the second hot pressing and compounding process. Finally, it is wound by the storage mechanism. The movable storage roller 21 moves up and down, and the wound composite sheet can be cached. The cutting mechanism 27 can select a laser cutting structure to cut the composite sheet. The storage mechanism conveys according to the frequency of the cutting mechanism 27 to realize efficient cutting of the composite sheet. Finally, the finished composite sheet is output through the blanking assembly. The blanking assembly can refer to the transfer assembly, so it will not be repeated here.
