[0059] The working principle of this utility model:

[0060] This utility model is equipped with a feeding component, a transfer component, a correction component, and a roller feeding component. After feeding and correction, the electrode roll 1 is conveyed to the composite pressing mechanism for hot pressing with the diaphragm roll 2. The composite pressing mechanism performs secondary hot pressing on the electrode roll 1 and the diaphragm roll 2 to form a composite sheet. The storage component stores the output composite sheet. Finally, the cutting mechanism 27 is matched to efficiently output the finished composite sheet. The working efficiency is high, the processing effect is good, and it meets the requirements of large-volume, large-size electrode hot pressing composite processing.

[0061] The feeding assembly can drive the lifting plate 4 to move up and down via the lifting unit 3. The lifting unit 3 can be a lifting screw, lifting cylinder, or other lifting structure. The lifting plate 4 can hold the electrode roll 1 to be processed. After the lifting plate 4 drives the electrode roll 1 to rise, the adsorption mechanism can move along the Y-axis direction via the adsorption Y-axis moving mechanism 7. Figure 1The lifting mechanism faces the direction of approaching or moving away from the correction platform; multiple connecting ends can be set at the bottom or sides of the support plate 5, and several suction cups 6 can be detachably connected to the multiple connecting ends. Adjust the adsorption Z-axis moving mechanism 8 to make the suction cups 6 descend and adhere to the adsorption electrode roll 1. The transfer component places the electrode roll 1 on the correction platform. The correction platform can correct the electrode roll 1 lowered by the adsorption mechanism. The correction drive unit 10 can drive the correction panel 9 to rotate the electrode roll 1 in the X-axis direction, Y-axis direction, Z-axis direction, thereby adjusting the position of the electrode roll 1. After the electrode roll 1 completes the correction, the transfer component conveys the corrected electrode roll 1 to the feeding roller assembly. The feeding clamping unit 12 can select a clamping arm and can move in the Y-axis direction. Each pair of opposite feeding clamping units 12 can control the distance between them (the two opposite feeding clamping units 12) through the feeding Y-axis moving unit 13, thereby realizing that each group of feeding clamping units 12 clamps or releases the electrode roll 1. Each pair of opposite feeding clamping units 12 is divided into a group, and multiple groups of feeding clamping units 12 can be set. The feeding X-axis moving unit 14 causes the clamped electrode roll 1 to move towards the pressure roller assembly. The moving end of the feeding X-axis moving unit 14 moves faster than the feeding belt 11. The electrode roll 1 is conveyed between the first upper pressure roller 16 and the first lower pressure roller 17. At the same time, the diaphragm roll 2 is simultaneously conveyed between the first upper pressure roller 16 and the first lower pressure roller 17. The first upper pressure roller 16, equipped with an upper heating element, and the first lower pressure roller 17, equipped with a lower heating element, are heated simultaneously, achieving the first hot-pressing composite to form a composite sheet. After being heated between the upper heating plate 22 and the lower heating plate 23, the composite sheet continues to be conveyed by the feeding belt 11 between the second upper pressure roller 18 and the second lower pressure roller 19 to complete the second hot-pressing composite process. Finally, it is wound up by the storage mechanism. The moving storage roller 21 moves up and down to buffer the wound composite sheet. The cutting mechanism 27 can be a laser cutting structure to cut the composite sheet. The storage mechanism conveys according to the frequency of the cutting mechanism 27 to achieve efficient cutting of the composite sheet. Finally, the finished composite sheet is output by the unloading assembly. The unloading assembly can be referred to as the transfer assembly, so it will not be described again.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
