The positive electrode CCD correction mechanism (not shown in the figure) and the negative electrode CCD correction mechanism 3 are parallel to each other. The positive electrode CCD correction mechanism is set on the worktable 1. The worktable 1 is also equipped with a diaphragm unwinding constant tension mechanism 4. The diaphragm unwinding constant tension mechanism 4 is laterally located at the end of the positive electrode conveying mechanism and the negative electrode conveying mechanism. A stacking table (not shown in the figure) is set on one side of the diaphragm unwinding constant tension mechanism 4. A cell transfer mechanism (not shown in the figure) is set on one side of the stacking table. The cell transfer mechanism is set on the worktable 1.

A cell adhesive application mechanism 9 is set on one side of the cell adhesive application mechanism. A finished product stacking mechanism 11 is set on one side of the cell adhesive application mechanism. The finished product stacking mechanism is set on the worktable 1.When the positive electrode feeding mechanism and the negative electrode feeding mechanism feed the positive electrode sheet and the negative electrode sheet to the positive electrode sheet conveying mechanism and the negative electrode sheet conveying mechanism respectively, and then transport the positive electrode sheet and the negative electrode sheet to the positive electrode sheet CCD correction mechanism and the negative electrode sheet CCD correction mechanism 3 respectively, the positive electrode sheet CCD correction mechanism and the negative electrode sheet CCD correction mechanism 3 respectively take CCD pictures of the positive electrode sheet and the negative electrode sheet to obtain the coordinate center line for correction and positioning, and then stack the positive electrode sheet and the negative electrode sheet after correction and positioning on the stacking table in sequence. Before stacking the positive electrode sheet and the negative electrode sheet, the diaphragm has been introduced into the stacking table by the diaphragm unwinding constant tension mechanism 4, so that when the positive electrode sheet and the negative electrode sheet are stacked, A cell separator is bonded between the positive and negative electrode sheets. After stacking, the stacked cell separator is pulled out by a cell transfer mechanism and thermally cut. The cell transfer mechanism then picks up the cell, rotates it, and places it into two sets of cell hot-pressing composite mechanisms for hot-pressing composite. The cell hot-pressing composite mechanism can be compatible with automatic four-sided C-shaped adhesive application or the cell transfer mechanism picking up the cell and placing it directly into the cell adhesive application mechanism 9 for adhesive application. Alternatively, the cell transfer mechanism can pick up the cell, rotate it, place it into two sets of cell hot-pressing composite mechanisms for hot-pressing composite, and then pick up the hot-pressed cell into the cell adhesive application mechanism 9 for adhesive application.

Second pressure blocks 8 are horizontally positioned on both sides of the support platform 13 surface, and are parallel to the first pressure blocks 7. Thus, the motors 6 can drive the first pressure blocks 7 onto the pressure platform. The bottom surface of the platen 5 moves up and down and presses against the second pressure block 8. Then, when the negative electrode feeding mechanism 2 transports the battery cell to be stacked and coated to the negative electrode CCD correction mechanism 3, the battery cell is detected by the negative electrode CCD correction mechanism 3. The detected battery cell is then transferred to the separator unwinding constant tension mechanism 5 for stacking and coating. The stacked and coated battery cell is transported to the surface of the support platform 13 and placed horizontally on the second pressure block 8. At this time, the motor 6 drives the first pressure block 7 to move down from the bottom surface of the pressure platform 5 and press against the second pressure block 8, thereby pressing the battery cell on the horizontal second pressure block 8. This makes the stacked and coated cells adhere to each other, and the motor 6 drives the first pressure block 7 to fall at a consistent speed, and the surface of the pressed battery cell has no indentations of varying depths.

The second material handling robot 15 is horizontally located on the rotary drive platform 17, and the rotary drive platform 17 drives the second material handling robot 15 to deflect its position, so that the battery cell pressed inside the support platform 13 can be clamped and transported to the battery cell adhesive applicator 9 for another adhesive application.
