[0002] When the laminator encapsulates the battery components, the atmospheric pressure is used as the external pressure to act on the components in a vacuum environment, and the battery components are heated by the heating plate to achieve lamination packaging. The heating plate is generally heated by circulating oil or electric heating tubes. However, no matter what heating method is used, during the feeding and discharging process of the laminator, the heating plate will not only be partially heated by the air, but also by the laminated battery components, which will cause uneven heat on the heating plate, thereby affecting the subsequent packaging quality of the battery components.

According to the temperature sensor, the temperature of the corresponding area is measured, and electromagnetic heating is carried out in time through the electromagnetic induction heater and the electromagnetic induction line, so that the temperature of each area of ​​the heating plate is within ±1.5°C of the preset value. The sub-heating zone is processed by processing multiple blind holes on the side wall of the plate body, and a connecting groove is set at the bottom of the blind hole. When the electromagnetic induction line is passed through, it is passed through the first blind hole, turned at the connecting groove and passed through the adjacent second blind hole, and so on. Finally, a continuous S-shaped electromagnetic induction line is passed through the sub-heating zone; and after all the electromagnetic induction lines are passed through, a blocking block is welded at the connecting groove to complete the processing of the heating plate. The side of the plate body welded with the blocking block is the bottom surface, and the corresponding top surface is used as the heating working surface.

[0006] Furthermore, the spacing between adjacent blind holes is 80-95 mm, and the minimum spacing between the electromagnetic induction lines in the first heating zone and the electromagnetic induction lines in the second heating zone is 80-95 mm.

[0007] Furthermore, the sub-heating zones in the left half zone and the right half zone are symmetrically arranged, and the spacing between the corresponding connecting grooves in the left half zone and the right half zone is 80-95 mm.

[0008] Furthermore, the thickness of the plate body is 40-60 mm, the diameter of the blind hole is 10-20 mm, and the blind hole is arranged in the middle position of the side wall of the plate body.

[0009] Furthermore, in order to ensure uniform heating of the plate body, the surface of the blocking block is arranged flush with the surface of the plate body.
