Description

Technical Field

[0001] The invention relates to the technical field of battery production, and in particular to a lamination device. Background Art

[0002] The existing stacking equipment for stacking positive electrode sheets, negative electrode sheets and diaphragms in a Z-shape generally includes a first outer suction cup manipulator, a second outer suction cup manipulator, a first inner suction cup manipulator, a second inner suction cup manipulator, a first deviation correction mechanism, a second deviation correction mechanism, a stacking mechanism, a diaphragm unwinding mechanism and a diaphragm deflection mechanism. The stacking mechanism is located between the first deviation correction mechanism and the second deviation correction mechanism. The first inner suction cup manipulator and the second inner suction cup manipulator are located between the first outer suction cup manipulator and the second outer suction cup manipulator in sequence, the first outer suction cup manipulator, the second outer suction cup manipulator, the first inner suction cup manipulator and the second inner suction cup manipulator are all located above the first deviation correction mechanism, the stacking mechanism and the second deviation correction mechanism, the diaphragm deflection mechanism is located above the stacking mechanism and between the first inner suction cup manipulator and the second inner suction cup manipulator, and the diaphragm unwinding mechanism is located to the right of the second outer suction cup manipulator. The first outer suction cup manipulator is connected to the first outer suction cup linear module, the second outer suction cup manipulator is connected to the second outer suction cup linear module, the first inner suction cup manipulator is connected to the first inner suction cup linear module, the second inner suction cup manipulator is connected to the second inner suction cup linear module, and the diaphragm deflection mechanism is respectively connected to the first deflection linear module and the second deflection linear module.

[0003] In the above structure, the first correcting mechanism and the second correcting mechanism are usually fixed and cannot move. In this way, when the first outer suction cup linear module drives the first outer suction cup manipulator to move to the first correcting mechanism to place the sucked negative electrode sheet on the first correcting mechanism, the first outer suction cup manipulator and the first correcting mechanism cannot move toward each other. When the first inner suction cup linear module drives the first inner suction cup manipulator to move to the first correcting mechanism to suck the negative electrode sheet on the first correcting mechanism, the first inner suction cup manipulator and the first correcting mechanism cannot move toward each other. In the process of the outer suction cup manipulator moving to the second deflection correction mechanism to place the sucked positive electrode sheet on the second deflection correction mechanism, the second outer suction cup manipulator and the second deflection correction mechanism cannot move toward each other. In the process of driving the second inner suction cup manipulator to move to the second deflection correction mechanism by the second inner suction cup linear module to suck the positive electrode sheet on the second deflection correction mechanism, the second inner suction cup manipulator and the second deflection correction mechanism cannot move toward each other. This results in a relatively long movement stroke of the first outer suction cup manipulator, the second outer suction cup manipulator, the first inner suction cup manipulator, and the second inner suction cup manipulator, thereby increasing the stacking time and reducing the stacking efficiency. In addition, the first outer suction cup manipulator, the second outer suction cup manipulator, the first inner suction cup manipulator, the second inner suction cup manipulator, and the diaphragm deflection mechanism are driven by different linear modules, respectively, which is costly.

[0029] Combination Figure 3As shown, the first external suction cup manipulator 10a is used to suck the negative electrode sheet on the negative electrode sheet transmission line and place the sucked negative electrode sheet on the first correction mechanism 30a. The second external suction cup manipulator 10b is used to suck the positive electrode sheet on the positive electrode sheet transmission line and place the sucked positive electrode sheet on the second correction mechanism 30b. The first external suction cup manipulator 10a and the second external suction cup manipulator 10b both include an external suction cup lifting linear module 12, an external suction cup mounting seat 13, an external suction cup rotating assembly 14, an external suction cup connecting seat 15 and an external suction cup assembly 16.

The multi-motor linear motor 3a is used to drive the external suction cup lifting linear module 12 to move left and right. One end of the outer suction cup mounting seat 13 is arranged on the outer suction cup lifting linear module 12, and the outer suction cup lifting linear module 12 is used to drive the outer suction cup mounting seat 13 to move up and down, and the left and right movement of the outer suction cup lifting linear module 12 can drive the outer suction cup mounting seat 13 to move left and right. The outer suction cup rotating assembly 14 is arranged at the other end of the outer suction cup mounting seat 13. The outer suction cup assembly 16 is located in front of the outer suction cup mounting seat 13 and below the outer suction cup mounting seat 13, and the outer suction cup assembly 16 and the outer suction cup mounting seat 13 are arranged vertically. The angle between the center line of the length direction of the outer suction cup connecting seat 15 and the center line of the length direction of the outer suction cup mounting seat 13 is an obtuse angle. One end of the outer suction cup connecting seat 15 is connected to the outer suction cup rotating assembly 14, and the other end of the outer suction cup connecting seat 15 is connected to the outer suction cup assembly 16. The center of the outer suction cup assembly 16 is located on the side of the rotation center of the outer suction cup connecting seat 15 away from the lamination mechanism 40, that is, it is eccentrically arranged relative to the rotation center of the outer suction cup connecting seat 15.

The deflection pressure plate 95 is driven by the deflection cylinder 96 to move toward the clamping roller 94, so that the diaphragm can be clamped by the clamping roller 94 and the deflection pressure plate 95. The diaphragm deflection mechanism 90 of the present invention has a deflection top plate 92 which is slidably connected to the large correction plate 82 of the diaphragm correction mechanism 80.

In this way, the diaphragm deflection mechanism 90 does not need to be provided with a structure for correcting the diaphragm, which reduces the weight of the diaphragm deflection mechanism 90, facilitates speed increase, and improves the stacking efficiency.

[0049] The working principle of the present invention is as follows: S1, the diaphragm unwinding mechanism 70 is in action: the unwinding motor 74 drives the unwinding air shaft 73 to rotate, so that the diaphragm can be unwound through the unwinding air shaft 73. The unwound diaphragm passes over the multiple support rollers 84 of the diaphragm correction mechanism 80 in sequence, then passes through the guide channel 821, then passes between the two lower rollers 98, then passes between the clamping roller 94 and the sway pressure plate 95, and then passes between the two upper rollers 99. The sway pressure plate 95 is driven by the sway cylinder 96 to move toward the direction close to the clamping roller 94, so that the diaphragm can be clamped by the clamping roller 94 and the sway pressure plate 95. When the unwound diaphragm is offset, the diaphragm correction mechanism 80 is in action: for example, when the diaphragm is offset forward, the correction linear motor drives the multiple support rollers 84 to move backward, so that the diaphragm can be corrected. When the diaphragm deviates backward, the correction linear motor drives the plurality of support rollers 84 to move forward, thereby correcting the deviation of the diaphragm.

[0050] The multi-motor linear motor 3a and the yaw linear module 3b act: the multi-motor linear motor 3a and the yaw linear module 3b drive the diaphragm yaw mechanism 90 to move leftward, so that the diaphragm can be driven to move leftward through the diaphragm yaw mechanism 90 to pull the diaphragm to a predetermined length and lay it on the stacking table 43 of the stacking mechanism 40. Then, the diaphragm is adsorbed through the plurality of adsorption holes 651 of the vacuum suction plate 65 of the diaphragm reversing mechanism 60.

[0051] S2, the second external suction cup manipulator 10b, the second deviation correction mechanism 30b, the multi-motor linear motor 3a, and the second deviation correction linear module 4b act as follows: first, the external suction cup lifting linear module 12 of the second external suction cup manipulator 10b drives a plurality of external suction cups 163 to move downward to a predetermined position, so as to suck the positive electrode sheet on the positive electrode sheet transmission line through a plurality of external suction cups 163. Then, the external suction cup lifting linear module 12 of the second external suction cup manipulator 10b drives a plurality of external suction cups 163 and the positive electrode sheet to move upward to the initial position.
