Description

Technical Field

[0001] The utility model relates to the technical field of battery production equipment, in particular to a lamination table device of a high-speed lamination machine. Background Art

[0002] The stacking machine is used for stacking, and its components include a diaphragm unwinding and feeding device, etc. The stacking machine consists of a diaphragm unwinding and feeding device, a multi-station composite material picking and paper swinging robot, a modular lifting workbench device, a modular paper pressing mechanism, a flat-plate special vacuum adsorption device, and an electrical control and operation panel (including a touch screen). The technical features are: 1. It automatically realizes the stacking of battery cells and is one of the key equipment for the automated production of square lithium batteries; 2. It is efficient and accurate, with full-process automated network monitoring.

[0003] The stacking machine is one of the key equipment in the production of square lithium batteries. It is generally composed of ten mechanisms: unloading mechanism, positive electrode material box, negative electrode material box, positive electrode secondary positioning mechanism, negative electrode secondary positioning mechanism, positive electrode feeding mechanism, negative electrode feeding mechanism, stacking table, gluing mechanism, and unloading mechanism. The working principle of the stacking machine is to load the positive and negative electrode sheets into the material box, and the manipulator moves left and right to pick up the electrode sheets in the positive and negative electrode material boxes. After secondary positioning, the positive and negative electrode sheets are alternately placed on the stacking table. The diaphragm is actively unwound, and the stacking table drives the diaphragm to move back and forth left and right to form a Z-shaped stack. After the stacking is completed, it is cut according to the set length and automatically sent out for manual gluing.

[0004] A stacking table device for a stacking machine disclosed in the Chinese utility model patent application disclosure CN 219066861 U includes a base, a driving assembly arranged on the base, a support seat, a stacking table connected to the support seat, and a connecting seat connected to the base and the support seat, wherein the connecting seat is slidably connected to the support seat; the support seat includes a sliding portion and a supporting portion, and the output end of the driving assembly is connected to the sliding portion. The utility model drives the support seat and the stacking table to reciprocate in the vertical direction through the driving assembly, and the support seat slides relative to the connecting seat, thereby stably adjusting the height of the stacking table in the vertical direction, which is convenient for stacking or pressing the battery poles on the stacking table. The additional connecting seat is provided to guide and limit the movement of the support seat, which is conducive to the stable and precise reciprocating movement of the support seat and the stacking table. The self-locking of the support seat and the stacking table is achieved through the connecting seat, so that the battery poles are more stable during the stacking process.

[0005] However, the device is not equipped with a hot pressing device. Traditional cold pressing of electrodes is suitable for metal materials, but not suitable for forming complex shapes. It has a long production cycle and high production costs. The hot pressing process is a compaction carried out at high temperature. The interlayer materials and electrode active materials filled in the battery cell will also soften, thereby reducing the interfacial tension between air, liquid and solid under the action of temperature. The device is not equipped with a dust removal mechanism. There will be various impurities in the chip manufacturing process. Contamination by impurities will cause the chip to fail electrically and cause the chip to be scrapped. Summary of the invention
