[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0043] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0044] For ease of description, spatial relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0045] In the prior art, the industry generally adopts manual winding to achieve the winding of the adhesive tape or insulating paper of the battery cell. The paper tube of the adhesive tape or insulating paper is put on the customized tooling, the battery cell is manually loaded, the starting end of the adhesive tape or insulating paper is attached to the battery cell, and then the adhesive tape or insulating paper is wound around the battery cell in circles, and finally the adhesive tape is semi-automatically cut. In the process of taping and winding, due to the different tension of manual winding, the product consistency is poor, and even warping, bulging, and misalignment occur, which affect the quality of the battery cell product. In addition, it is easy to cause the battery cell to be stressed and strained, resulting in safety problems.

[0046] In order to solve the technical problem that the winding of battery cell adhesive tape or insulating paper is realized by manual operation in the prior art, resulting in poor product consistency, and even warping, bulging, and dislocation that affect the quality of battery cell products, the present application provides a battery cell adhesive winding device, which can realize the automated production of self-adhesive winding of battery cells, avoid the problems of warping, bulging, and dislocation caused by manual adhesive winding, and ensure the consistency of battery cell products and the quality of finished products. By controlling the start and stop of the feed roller, the winding length and the tension of the battery cell can be controlled to avoid safety problems caused by pressure strain on the battery cell.

[0047] Figure 1 A battery cell adhesive tape winding device provided in an embodiment of the present application includes a base 1, a feeding mechanism 2, a clamping mechanism 3, a first adhesive tape mechanism 4 and a cutting mechanism 5. The base 1 has a feeding end 11 and a unloading end 12 arranged opposite to each other; the feeding mechanism 2 is arranged at the feeding end 11 of the base 1, and the feeding mechanism 2 includes a first bracket 21 and a feeding roller 22. The first bracket 21 is movably arranged on the base 1, and the feeding roller 22 is rotatably arranged on the first bracket 21 for conveying materials; the clamping mechanism 3 is provided on the first bracket 21, and the first adhesive tape winding device includes a first adhesive tape winding device, a first adhesive tape winding device, a first adhesive tape winding device, and a first adhesive tape winding device. The mechanism 3 is arranged at the unloading end 12 of the base 1, and the clamping mechanism 3 includes a clamping member 33 for clamping the battery cell. The clamping member 33 is rotatably arranged on the base 1 so that the battery cell has a static state and a rotating state; the first gluing mechanism 4 is arranged between the feeding roller 22 and the clamping member 33. When the battery cell is in a static state, the first gluing mechanism 4 is used to stick the material on the surface of the battery cell; the cutting mechanism 5 is arranged between the feeding roller 22 and the clamping member 33. The cutting mechanism 5 is used to cut the material.

[0048] It can be understood that, initially, the clamping member 33 clamps the battery cell to be glued, and the material (tape or insulating paper) in a tensioned state is wound on the feed roller 22. Then the first bracket 21 moves relative to the base 1 close to the clamping member 33, driving the feed roller 22 close to the battery cell to be glued, and when the battery cell is in a stationary state, that is, when the clamping member 33 is stationary relative to the base 1, the first glue mechanism 4 sticks the starting end of the material on the surface of the battery cell. The clamping member 33 is driven to rotate, and the feed roller 22 is driven to rotate at the same time. The rotation speed of the feed roller 22 is adapted to the rotation speed of the clamping member 33, so that the material (tape or insulating paper) is wound around the surface of the battery cell, which can realize the automatic production of glue-applying and winding of the battery cell, avoid the problems of warping, bulging, and dislocation caused by manual glue-applying and winding, and ensure the consistency of the battery cell products and the quality of the finished products. By controlling the start and stop of the feeding roller 22, the winding length and the tension of the battery cell can be controlled to avoid safety problems caused by pressure strain on the battery cell.

[0049] In some embodiments, Figure 2As shown, the feeding mechanism 2 includes an expansion shaft 23 and a pressure roller 24. The expansion shaft 23 is rotatably arranged on the first bracket 21, and the expansion shaft 23 is arranged close to the feeding end 11 of the base 1. The pressure roller 24 is movably arranged on the first bracket 21 to have a first state of being in contact with the feeding roller 22 and a second state of being separated from the feeding roller 22. The expansion shaft 23 can adopt a hand expansion shaft in the prior art, or a gas expansion shaft in the prior art. The structure and working principle of the hand expansion shaft and the gas expansion shaft can refer to the prior art. The paper tube of the material is sleeved on the expansion shaft 23, and the expansion shaft 23 is used to support the inner wall of the paper tube, thereby transmitting torque. A magnetic powder brake can also be arranged on the first bracket 21, and the magnetic powder brake is connected to the expansion shaft 23 to control the start and stop of the expansion shaft 23. Specifically, the nip roller 24 and the feed roller 22 are parallel to each other. When the nip roller 24 is in the second state, the material passes through the feeding space between the nip roller 24 and the feed roller 22, and then the nip roller 24 is controlled to be close to the feed roller 22 relative to the first bracket 21 to reach the first state. By utilizing the friction between the nip roller 24 and the feed roller 22, when the feed roller 22 rotates, the material can be moved toward the clamping member 33.

[0050] Furthermore, if Figure 2 As shown, a support frame 213 is provided on the first bracket 21, and both ends of the feed roller 22 are rotatably connected to the support frame 213, and an eighth cylinder 214 is provided on the support frame 213. A lifting frame 215 is provided at the power output end of the eighth cylinder 214, and both ends of the press roller 24 are rotatably connected to the lifting frame 215. The eighth cylinder 214 drives the lifting frame 215 to move up and down relative to the support frame 213, and the lifting frame 215 drives the press roller 24 to move up and down, and the distance between the press roller 24 and the feed roller 22 can be adjusted, so as to appropriately adjust the tension on the material.

[0051] In some embodiments, a positioning roller 25 and a first sensor are disposed on the first bracket 21. The positioning roller 25 is disposed close to the feed roller 22. The positioning roller 25 and the feed roller 22 are parallel to each other. The first sensor is used to detect whether the material passes through the feed space formed between the feed roller 22 and the pressure roller 24. The positioning roller 25 and the feed roller 22 are parallel to each other. The starting end of the material can be wound around the positioning roller 25 and then pass through the feed space formed between the feed roller 22 and the pressure roller 24. The detection end of the first sensor faces the material to detect whether the material passes through the feed space, so as to realize subsequent feeding control. Optionally, as Figure 3As shown, two positioning rollers 25 may be provided, and the two positioning rollers 25 are arranged opposite to each other in a third direction, which may be the Z direction shown in the figure, and the starting end of the material may be wound around the two positioning rollers 25 in sequence. Optionally, three positioning rollers 25 may be provided, wherein two positioning rollers 25 are respectively located at both ends of the feeding roller 22, so as to better position the material. The first sensor may be a distance sensor, a position sensor, etc. in the prior art.

[0052] In some embodiments, Figure 3 and Figure 4 As shown, a fixed roller 26 and a first adjusting roller 27 are arranged on the first bracket 21. The fixed roller 26 and the first adjusting roller 27 are arranged away from the feeding roller 22. The fixed roller 26 and the first adjusting roller 27 are located on the same side of the first bracket 21. The fixed roller 26 and the first adjusting roller 27 are parallel to each other and staggered in the second direction. The first direction is the moving direction of the first bracket 21, and the second direction intersects with the first direction. The first adjusting roller 27 is movably arranged on the first bracket 21. For ease of understanding, the first direction may be the X direction in the figure, and the second direction may be the Y direction in the figure. The starting end of the material passes through the first adjusting roller 27 and the fixed roller 26 in sequence, thereby increasing the tension on the material. At the same time, by adjusting the distance between the first adjusting roller 27 and the fixed roller 26, the tension of the material can be adjusted. After the material is wound on the surface of the battery cell, the pressure on the battery cell can be controlled to prevent wrinkles or bubbles on the adhesive surface of the battery cell product.

[0053] Furthermore, the first bracket 21 is provided with a first cylinder 211 and a first movable plate 212, the power output end of the first cylinder 211 is connected to the first movable plate 212, the first bracket 21 is provided with a first opening, and the first movable plate 212 is connected to the first adjusting roller 27 through the first opening. The first cylinder 211 drives the first movable plate 212 to move up and down relative to the first bracket 21, so that the distance between the first adjusting roller 27 and the fixed roller 26 can be adjusted, thereby adjusting the tension of the material.

[0054] In some embodiments, Figure 5 and Figure 6 As shown, the first gluing mechanism 4 includes a second bracket 41 and a vacuum suction head 42. The second bracket 41 is arranged on the side of the first bracket 21 close to the clamping member 33, and the vacuum suction head 42 is movably arranged on the second bracket 41. The vacuum suction head 42 can be connected to an external negative pressure device. After the external negative pressure device is working, the vacuum suction head 42 provides a certain adsorption force to adsorb the adhesive paper away from the sticky side. Initially, the first bracket 21 moves relative to the base 1 close to the clamping member 33, driving the feeding roller 22 to approach the battery cell to be glued. When the battery cell is in a stationary state, the vacuum suction head 42 moves upward with the material to adhere the starting end of the material to the surface of the battery cell.

[0055] The first glue sticking mechanism 4 includes a second cylinder 43, a lifting bracket 44, and a second slide rail 45 and a first slider 46 that slide with each other. The second cylinder 43 is arranged on the second bracket 41. The power output end of the second cylinder 43 is arranged away from the base 1 and connected to the lifting bracket 44. The vacuum suction head 42 is arranged on the lifting bracket 44. The second slide rail 45 is arranged on the second cylinder 43. The length direction of the second slide rail 45 is parallel to the third direction. The first direction is the moving direction of the first bracket 21. The third direction intersects with the first direction and the second direction. The side of the first slider 46 away from the second slide rail 45 is connected to the lifting bracket 44. The third direction can be the Z direction shown in the figure. The second cylinder 43 drives the lifting bracket 44 to move up and down along the second direction. Through the sliding connection between the second slide rail 45 and the second slider, the vacuum suction head 42 is driven to move up and down. After the starting end of the material is attached to the surface of the battery cell, the second cylinder 43 controls the lifting bracket 44 to move downward to stay away from the battery cell.

[0056] In some embodiments, Figure 5 and Figure 7 As shown, the cutting mechanism 5 includes a first cutter 51 and a second cutter 52. The first cutter 51 is lifted and arranged on the second bracket 41. The orthographic projection of the first cutter 51 on the base 1 and the orthographic projection of the vacuum suction head 42 on the base 1 do not overlap each other. The second cutter 52 is lifted and arranged on the base 1. The first cutter 51 and the second cutter 52 are arranged opposite to each other. When the material is wound to a set length, the first bracket 21 drives the second bracket 41 to approach the battery cell. After the second bracket 41 reaches the set position, the first cutter 51 and the second cutter 52 are controlled to move toward each other, that is, the first cutter 51 moves downward and the second cutter 52 moves upward to cut the material. The orthographic projection of the first cutter 51 on the base 1 and the orthographic projection of the vacuum suction head 42 on the base 1 do not overlap each other, so as to avoid the first cutter 51 from colliding with the vacuum suction head 42 during the downward movement.

[0057] Furthermore, a third cylinder 53 is provided on the second bracket 41, and a power output end of the third cylinder 53 is connected to the first cutter 51; a third bracket 54 is provided on the base 1, and a fourth cylinder 55 is provided on the third bracket 54, and a power output end of the fourth cylinder 55 is connected to the second cutter 52. The first cutter 51 is driven to move toward the second cutter 52 by the third cylinder 53, and the second cutter 52 is driven to move toward the first cutter 51 by the fourth cylinder 55, and the shear force between the first cutter 51 and the second cutter 52 is utilized to realize the cutting of the material.

[0058] During the cutting process, the material is prone to rebound under the action of tension, and the material may adhere to other parts or itself, making the starting end unusable. Before the next gluing, it is necessary to manually cut off the scrapped section and adjust the starting end of the material, which increases the labor cost and rework cost. Therefore, the embodiment of the present application designs a first glue pressing roller 47 to press the material synchronously during the cutting process to prevent the material from rebounding. The specific design is described as follows.

[0059] In some embodiments, Figure 5 As shown, a first rubber pressing roller 47 corresponding to the vacuum suction head 42 is provided on the second bracket 41, and the first rubber pressing roller 47 and the vacuum suction head 42 are arranged opposite to each other in the second direction. The first rubber pressing roller 47 is arranged on the side of the first cutter 51 close to the feeding end 11; a fifth cylinder 48 is provided on the second bracket 41, and the power output end of the fifth cylinder 48 faces the vacuum suction head 42 and is connected to the first rubber pressing roller 47. Before cutting the material, the fifth cylinder 48 drives the first rubber pressing roller 47 to move downward until it abuts against the vacuum suction head 42. The pressure between the first rubber pressing roller 47 and the vacuum suction head 42 can be used to avoid the material from rebounding after cutting, thereby reducing the cost of rework and adjustment.

[0060] In some embodiments, Figure 5 As shown, the second bracket 41 is movably provided with a second adjusting roller 49, the second bracket 41 is provided with a sixth cylinder and a second moving plate, the power output end of the sixth cylinder is connected to the second moving plate, the second bracket 41 is provided with a second opening, and the end of the second adjusting roller 49 close to the second bracket 41 is connected to the second moving plate through the second opening. The starting end of the material passes through the first adjusting roller 27, the fixed roller 26 and the second adjusting roller 49 in sequence, thereby increasing the tension on the material; the sixth cylinder drives the second moving plate to move up and down relative to the second bracket 41, driving the second adjusting roller 49 to move up and down, thereby adjusting the distance between the second adjusting roller 49 and the fixed roller 26, and adjusting the tension of the material. After the material is wound on the surface of the battery cell, the pressure on the battery cell can be controlled to prevent wrinkles or bubbles on the adhesive surface of the battery cell product.

[0061] In some embodiments, Figure 2 As shown, the feeding mechanism 2 includes a moving module, and the moving module includes a first slide rail 28 and a slide 29. The first slide rail 28 is arranged on the base 1, and the length direction of the first slide rail 28 is parallel to the first direction; the slide 29 is slidably connected to the first slide rail 28, and the first bracket 21 is arranged on the slide 29.
