TECHNICAL FIELD
[0001] The present disclosure relates generally to the technical field of lithium battery. More specifically, the present disclosure relates to a coil cutting and removing device and a lamination machine. BACKGROUND
[0002] The lamination machine is a key equipment in the lithium battery manufacturing process, mainly used for stacking the positive and negative electrode sheets and the separator alternately to form the bare battery cell. With the increasing demand for energy density of electric vehicles, and the increase in size and decrease in thickness of square battery cells, the importance of the lamination process is increasingly prominent. The working principle of the lamination machine is to load the positive and negative electrode sheets into the magazine, and the mechanical hand moves left and right to pick up the electrode sheets in the positive and negative electrode magazines, and after secondary positioning, the positive and negative electrode sheets are alternately placed on the lamination table. The separator is actively unwound, and the lamination table drives the separator to move left and right reciprocally to form a Z-shaped winding. After lamination is completed, it is cut off according to the set length and automatically sent out for manual rubberizing.
[0003] When the separator of the lamination machine is changed, the new and old separators need to be connected together by the tape joint head. The existing lamination machine cannot automatically discharge the tape joint head when working, and needs to be empty-laminated with the separator, or directly laminated with the electrode sheet to use up the tape joint head, and then the electrode core is scrapped; when the separator is empty-laminated or laminated, about 20-30 meters of separator are used for each electrode core, which causes waste of the separator and causes the electrode sheet to be scrapped, and even the abnormal electrode core with the tape joint head flows to the next process, causing problems in the subsequent process. How to cut and remove the tape joint head of the separator is a difficult point in the optimization of battery production line equipment and the improvement of production line efficiency.

[0033] The specific embodiments of the present disclosure will now be described in detail below with reference to the accompanying drawings.
[0034] The laminating machine is a production machine for laminated cells of lithium batteries. In the production process of lithium batteries, the laminating step mainly involves a positive electrode feeding mechanism, a negative electrode feeding mechanism, a diaphragm feeding mechanism, a laminating platform, and a cell taking-out mechanism. The pre-prepared positive electrode slurry and negative electrode slurry are respectively extruded or sprayed onto metal plates, and then subjected to drying, punching and other steps to finally form positive and negative electrode sheets for laminating. The positive electrode feeding mechanism, the negative electrode feeding mechanism, and the diaphragm feeding mechanism respectively deliver the positive electrode sheet, the negative electrode sheet, and the diaphragm to the laminating platform. The positive electrode sheet, the negative electrode sheet, and the diaphragm are sequentially stacked on the laminating platform, and the positive electrode sheet and the negative electrode sheet are separated by the diaphragm. Finally, the cell taking-out mechanism takes out the stacked cell.
[0035] The positive electrode sheet and the negative electrode sheet are both sheet materials, and are rectangular in overall shape and light in mass. Therefore, the positive electrode feeding mechanism and the negative electrode feeding mechanism generally use suction disc devices to suck the positive electrode sheet and the negative electrode sheet, and alternately place the positive electrode sheet and the negative electrode sheet into the stacking platform for stacking. The positive electrode feeding mechanism and the negative electrode feeding mechanism generally use a secondary positioning method, that is, the electrode sheet is first taken out from the electrode sheet storage area with relatively loose activity space, and is placed into the electrode sheet position adjustment area with activity space slightly larger than the size of the electrode sheet to adjust the position of the electrode sheet, and then the electrode sheet after position adjustment is sucked out and placed into the stacking platform, so as to improve the accuracy of the electrode sheet placement position. After the positive electrode sheet or the negative electrode sheet is placed, the separator feeding mechanism places continuous separators into the stacking platform, so that the electrode sheet just placed and the electrode sheet to be placed later are physically isolated by the separator, so as to prevent the positive electrode sheet from contacting the negative electrode sheet. In this way, the positive electrode sheet, the separator, the negative electrode sheet and the separator are sequentially placed, and the electrode core monomer in a "sandwich" structure is stacked on the object platform. A plurality of electrode core monomers in the "sandwich" structure are stacked to form the electrode core of the battery. When the number of positive electrode sheets and the number of negative electrode sheets reach the preset value, the placement of the electrode sheet and the separator is stopped, the separator is cut off, and the battery electrode core can be clamped out by the electrode core taking-out mechanism.

The aforementioned separator film can enter the aforementioned first roller from the second direction and wrap around the aforementioned roller, and then exit the aforementioned first roller in the first direction.
[0042] In some embodiments, the aforementioned clamping portion 12 can move back and forth in the first direction when the aforementioned first conveying portion 111 moves back and forth in the first direction, and the aforementioned clamping portion 12 can be located at a first position when the aforementioned clamping portion 12 contacts the separator film that exits the first roller in the first direction.

Preferably, the second side of the aforementioned first clamping plate 121 can be connected to the aforementioned second clamping plate 122 by a pneumatic cylinder. Specifically, the upper surface of the aforementioned first clamping plate 121 can be provided with a first pneumatic cylinder, the first moving rod of the aforementioned first pneumatic cylinder can be parallel to the third direction, and the end of the aforementioned first moving rod can be provided with a second pneumatic cylinder.

When a diaphragm is arranged between the first plane and the second plane, the second plane can move in the second direction and drive the diaphragm to contact the first plane, so that the first plane and the second plane clamp the diaphragm.

The cutting component 20 can also correspond to the area where the second end 302 of the diaphragm c and the first end 401 of the diaphragm d are connected above it. After cutting the aforementioned second end 102 of the diaphragm a and the first end 201 of the diaphragm b, the aforementioned diaphragm a and diaphragm b can be separated. After cutting the aforementioned second end 302 of the diaphragm c and the first end 401 of the diaphragm d, the aforementioned diaphragm d and diaphragm c are separated. Further, the aforementioned cutting component can also be provided with a fusion part, which can provide high temperature in the fusion area 211 to fuse the diaphragm.

[0067] In some embodiments, on the second side of the first clamping plate 121, the lower surface of the first clamping plate can form a first plane, and the upper surface of the second clamping plate 122 can form a second plane. When a diaphragm is provided between the first plane and the second plane, the second plane can move in a second direction and cause the diaphragm to contact the first plane, so that the first plane and the second plane clamp the diaphragm. At this time, the conveying part moves in the first direction, thereby causing the second side of the first clamping plate 121 to move between a first position and a second position.
[0068] In some embodiments, the cutting component 20 comprises a hot knife.
[0069] In some embodiments, the hot knife can heat the material to its melting or burning point by a heat source, such as an electric arc or a laser, to achieve the cutting and separation of the material. It can be understood that the use of the hot knife can achieve the fast cutting and fusing of the membrane, and reduce the loss of the membrane.
[0070] In some embodiments, the first side of the cutting component 20 is provided with a blade for cutting the roll material, and the inside of the cutting component 20 is provided with a heating component for heating the cutting component 20.
[0071] In some embodiments, the roll material can comprise a membrane, and the cutting component 20 can further comprise a cutting part 23 and a moving rod 24.

One end of the detection component faces the roll material, and is connected to the laminator through a connecting rod and arranged above the first roller. The detection component can comprise a color marker sensor, and the color marker sensor can detect the membrane at the entering end of the first roller. It can be understood that when the color marker sensor detects the adhesive tape between the first membrane and the second membrane, the color marker sensor can transmit a signal to the controller, and the controller can control the clamping component to clamp the membrane from the first position to the second position, and then cut the membrane by the cutting component.
[0074] In some embodiments, the device further comprises a deviation correction component arranged in the third direction of the cutting component, and connected to the conveying component and / or the cutting component.
[0075] In some embodiments, the aforementioned deviation rectifying component can include a sensor that can detect the edge position of the diaphragm and send a position deviation signal to the controller. When the diaphragm deviates, the deviation rectifier senses the degree of deviation through the detection signal, and then generates a counterforce or feedback signal to offset the deviation and restore the web material to a balanced state.
[0076] By setting the deviation rectifying component, the precise alignment of the diaphragm during production can be ensured, and the production efficiency and product quality can be improved.
[0077] The disclosed embodiments also provide a lamination machine, which includes the web material cutting and removing device as described above, and the web material is a battery diaphragm material. When the diaphragm needs to be changed, the lamination machine can adhere the new and old diaphragms together through the adhesive tape, and the adhesive tape can be discharged through the diaphragm waste discharging device, which can reduce the waste of the diaphragm and the low efficiency caused by changing the diaphragm on the lamination machine.
