Description

Technical Field

[0001] This utility model belongs to the technical field of battery cell manufacturing process, specifically relating to a battery cell bonding mechanism and a battery cell bonding system. Background Technology

[0002] In the lithium-ion battery manufacturing industry, the tabs, as a key component for internal conductivity of the cell, have a crucial impact on the overall quality of the cell.

[0003] During the manufacturing process of battery cells, to prevent damage during certain processes or to increase the stability of the cell structure, the head of the cell is usually coated with adhesive. After the initial coating, a portion of the adhesive paper protrudes from the end face of the adhesive-coated end. To improve the quality, appearance, and insulation of the cell, a pressing operation is subsequently performed on the adhesive-coated end. This involves pressing the protruding adhesive paper flat to the adhesive-coated end and covering the electrode sheet on the end face of the adhesive-coated end.

[0004] Traditional adhesive bonding devices use a pressing block that moves parallel to the end face to bend and flatten the adhesive paper onto the bonding surface. However, this method cannot adapt to adhesive paper of different shapes. Especially when dealing with cylindrical battery cells, during the process of the pressing block moving parallel to the end face to press the adhesive paper, the round adhesive paper may exhibit defects such as outward flipping, resulting in wrinkles on the outer circumference that cannot be flattened, thus reducing the bonding quality of the battery cell.

[0005] Therefore, how to provide a battery cell bonding mechanism that can improve the bonding effect is a problem that needs to be solved by people in related technical fields. Utility Model Content

[0006] To address the shortcomings of the prior art, this utility model provides a battery cell pressing mechanism and a battery cell pressing system. By setting pressing claws, the adhesive paper is prevented from flipping outward during the pressing process, thereby improving the quality of battery cell pressing.

[0007] The technical effects to be achieved by this utility model are realized through the following technical aspects:

[0008] In a first aspect, this utility model provides a battery cell bonding mechanism, comprising:

[0009] A pressure-pressing claw used for pressing the adhesive end of the battery cell;

[0010] The pressing claw has a guide portion inside, and the pressing claw has a guide surface surrounding the guide portion and a pressing surface located at the end of the guide portion;

[0011] After the adhesive end of the battery cell passes the guide surface, the pressing surface abuts against the adhesive end to press the adhesive paper protruding from the adhesive end onto the end face of the adhesive end.

[0012] Preferably, it further includes a pressure seat and a first driving member, the first driving member driving the pressure seat to move, and the pressure claw moving closer to or away from the adhesive end through the pressure seat, the pressure claw being detachably connected to the pressure seat.

[0013] Preferably, a buffer surface is further connected between the guide surface and the pressing surface, and the buffer surface is parallel to the extending direction of the guide portion.

[0014] Preferably, along the direction in which the guide portion extends, the end of the guide portion is also connected to a receiving portion for tab retraction, and the pressing surface is located on the outer side of the periphery of the receiving portion.

[0015] Secondly, this utility model also provides a battery cell bonding system, including...

[0016] The limiting mechanism and any of the above-described battery cell pressing mechanisms;

[0017] The limiting mechanism is disposed opposite to the cell pressing mechanism, and the limiting mechanism includes a limiting block;

[0018] The cell pressing mechanism and the limiting mechanism clamp the cell relative to each other, and the cell pressing mechanism presses the adhesive paper onto the adhesive end.

[0019] Preferably, the limiting mechanism includes a second driving member, and the limiting block moves closer to or further away from the battery cell under the action of the second driving member.

[0020] Preferably, a transfer mechanism is further provided between the limiting mechanism and the cell pressing mechanism. The transfer mechanism includes a third driving member and a pneumatic clamping assembly for gripping the cell. The pneumatic clamping assembly moves the cell under the action of the third driving member to align the cell with the pressing claw.

[0021] Preferably, the device further includes a fixing plate, which is disposed opposite to the cell pressing mechanism, and the limiting mechanism and the transfer mechanism are both connected to the fixing plate.

[0022] Preferably, the device further includes a positioning and correction mechanism located upstream of the cell pressing mechanism, the positioning and correction mechanism including a guide block for positioning the cell.

[0023] Preferably, it further includes a cell feeding mechanism, wherein the cell pressing mechanism and the limiting mechanism are respectively disposed on both sides of the cell feeding mechanism.

[0024] In summary, this utility model has at least the following advantages:

[0025] 1. This utility model provides a battery cell pressing mechanism that uses pressing claws to press protruding adhesive paper onto the end face of the battery cell, preventing the adhesive paper from flipping outwards during the pressing process and achieving a good pressing effect. The pressing claws have a guide portion inside that provides movement space for the battery cell. A guide surface located around the guide portion restricts and guides the adhesive paper protruding from the battery cell end face, preventing it from flipping outwards and guiding it to retract inwards. The pressing teeth have a pressing surface at the end of the guide portion for pressing the protruding adhesive paper onto the end face of the adhesive-applied end of the battery cell.

[0026] Compared to the traditional method of pressing adhesive onto the surface, the adhesive pressing claw improves the adhesive quality more effectively because it combines guiding and pressing functions. Especially when applying adhesive to round ends, the guiding and pressing surfaces of the claw allow the protruding adhesive paper to naturally fold and flatten onto the end face, preventing the adhesive paper from flipping outwards and maximizing the protection of the end face quality of the round battery cell. Furthermore, the adhesive pressing claw's integrated guiding and pressing surfaces result in a streamlined structure.

[0027] 2. This utility model also provides a battery cell pressing system, which uses the cooperation of a battery cell pressing mechanism and a limiting mechanism to limit and press the battery cell, resulting in good pressing quality. Furthermore, since the battery cell pressing mechanism also functions as a guide and presser, it can limit, guide, and press the adhesive paper protruding from the battery cell during the approach process. Therefore, the battery cell pressing system also features high efficiency and a simple structure. Attached Figure Description

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0051] Example 1:

[0052] Please see the appendix Figure 1-6 This embodiment provides a battery cell pressing mechanism 10, which is used to press the adhesive paper protruding from the battery cell onto the adhesive end face of the battery cell and prevent the adhesive paper from turning outward during the pressing process, thereby achieving good pressing quality.

[0053] Specifically, the cell pressing mechanism 10 includes a pressing base 11 and pressing claws 12 connected to the pressing base 11. The pressing claws 12 are detachably connected to the pressing base 11, so that the model of the pressing claws 12 can be changed as needed to adapt to different shapes or sizes of cell 70 and their adhesive tape 71.

[0054] like Figures 2 to 5 As shown, the pressure-pressing claw 12 has a guide portion 13 inside, which provides space for the battery cell to move. In this embodiment, the pressure-pressing claw 12 is provided with a plurality of pressure-pressing teeth 121, which surround and form the guide portion 13 and the guide inlet 131 communicating with the guide portion 13. During pressure pressing, the adhesive end 72 of the battery cell 70 enters the guide portion 13 from the guide inlet 131, and then the pressure is achieved under the action of the pressure-pressing teeth 121.

[0055] Along the extending direction of the guide portion 13, the pressure teeth 121 are sequentially provided with a guide surface 1211 and a pressing surface 1212. The guide surface 1211 surrounds the guide portion 13, and the direction of the guide surface 1211 from the guide inlet 131 to the pressing surface 1212 is inclined towards the center line of the pressure teeth 12. Therefore, the width of the guide portion 13 gradually narrows along the extending direction, so that the adhesive paper 71 protruding from the adhesive end 72 of the battery cell 70 moves towards the center line under the action of the guide surface 1211, and prevents it from turning outward.

[0056] The end of the guide portion 13 is a pressing surface 1212 for abutting against the adhesive end 72 of the battery cell 70. In this embodiment, the pressing surface 1212 is parallel to the end face of the adhesive end 72 of the battery cell 70 and is bent relative to the guide surface 1211. As the adhesive end 72 of the battery cell 70 gradually approaches the pressing surface 1212, the adhesive tape 71 protruding from the adhesive end 72 of the battery cell 70 is pressed against the end face of the adhesive end 72 under the action of the pressing surface 1212. In this process, the pressing claw 12 serves both to guide and press the adhesive tape 71, while also preventing the adhesive surface of the adhesive tape 71 from turning outwards, and ensuring that the wrinkles generated on the forming surface of the adhesive tape 71 are on the end face of the adhesive end 72 of the battery cell 70, effectively improving the quality of the battery cell 70.

[0057] In some embodiments, the cell pressing mechanism 10 further includes a first driving member 15. The first driving member 15 may be a slide cylinder. The first driving member 15 drives the pressing seat 11 to move, and through the pressing seat 11, it links the pressing claw 12, allowing the pressing claw 12 to approach or move away from the adhesive end 72 of the cell 70. This controls the pressing process between the pressing claw 12 and the cell 70, and also helps to increase the strength of the pressing claw 12 when pressing the adhesive paper 71. In addition, the first driving member 15 may also drive the pressing claw 12 to cooperate with other mechanisms to complete the pressing process.

[0058] In some embodiments, to optimize the adhesive bonding effect, a buffer surface 1213 is also connected between the guide surface 1211 and the pressing surface 1212. The buffer surface 1213 is parallel to the extending direction of the guide portion 13. The portion containing the buffer surface 1213 encloses a buffer space for the adhesive tape 71. As the adhesive end 72 of the battery cell 70 moves toward the pressing surface 1212, the adhesive tape 71 protruding from the adhesive end 72 is retracted under the action of the guide surface 1211, and then passes through the buffer surface 1213 until the entire adhesive tape 71 protruding from the adhesive end 72 has passed through the guide, at which point the adhesive tape 71 gradually comes into contact with the pressing surface 1212. The buffer surface 1213 is configured to provide sufficient guiding buffer space for the adhesive tape 71 protruding from the adhesive end 72, so that the adhesive tape 71 is completely guided before coming into contact with the pressing surface, which is conducive to the natural formation of wrinkles. In this embodiment, the buffer surface 1213 is bent at the end of the guide surface 1211 and is parallel to the extension direction of the guide portion 13. Then, the end of the buffer surface 1213 is connected to the pressing surface 1212. That is, the guide surface 1211, the buffer surface 1213 and the pressing surface 1212 are in a stepped shape, so that when the adhesive paper 71 passes through the guide portion 13, it can naturally form wrinkles at the adhesive end 72 of the battery cell 70 and is easy to be flattened by the pressing surface 1212.

[0059] In some embodiments, since the tab 74 also protrudes beyond the adhesive end 72, a receiving portion 14 is connected to the end of the guide portion 13 to prevent damage to the tab 74 during the pressing of the adhesive paper 71. In this embodiment, a limiting sidewall 1214 is connected to one end of the pressing surface 1212 near the center line of the pressing claw 12. The limiting sidewall 1214 extends along the extending direction of the guide portion 13, and the space formed by the plurality of limiting sidewalls 1214 is the receiving portion 14. The pressing surface 1212 is located on the periphery of the receiving portion 14. The receiving portion 14 and the guide portion 13 are connected and are both hollow structures. As the adhesive end 72 of the battery cell 70 approaches the end of the guide portion 13, the adhesive tape 71, which is located on the outer periphery of the end face of the adhesive end 72 and protrudes from the end face, is pressed against the end face of the adhesive end 72 under the action of the guide surface 1211 and the pressing surface 1212. The tab 74 located on the end face of the adhesive end 72 passes through the guide portion 13 and enters the receiving portion 14, avoiding contact between the tab 74 and the pressing surface 1212 on the periphery of the receiving portion 14, thereby preventing the tab 74 from being damaged.

[0060] Example 2:

[0061] Based on Embodiment 1, this embodiment provides a battery cell pressing adhesive system 100. The battery cell pressing adhesive system 100 uses a battery cell pressing adhesive mechanism 10 to press the adhesive paper 71 of the battery cell 70. For similarities, please refer to Embodiment 1. The battery cell pressing adhesive system 100 is described below.

[0062] Please refer to Figures 7 to 10The battery cell pressing system 100 includes a limiting mechanism 20 and a battery cell pressing mechanism 10. The limiting mechanism 20 is disposed opposite to the battery cell pressing mechanism 10 and is used to cooperate with the battery cell pressing mechanism 10 to clamp the battery cell 70, so as to make the process of the battery cell pressing mechanism 10 pressing the battery cell 70 stable. The limiting mechanism 20 includes a limiting block 21 at the end away from the adhesive end 72. In use, the adhesive end 72 of the battery cell 70 is close to the pressing claw 12 of the battery cell pressing mechanism 10, and the other end of the battery cell 70 is limited by the limiting block 21 until the battery cell pressing mechanism 10 presses the adhesive paper 71 onto the adhesive end 72 of the battery cell 70.

[0063] In this embodiment, the battery cell 70 is a cylindrical battery cell 70. One end of the battery cell 70 is an adhesive end 72, and adhesive tape 71 is attached to the side of the battery cell 70, with a portion of the adhesive tape 71 protruding beyond the adhesive end 72. The other end of the battery cell 70 is a limiting end 73. The battery cell pressing adhesive mechanism 10 is located near the adhesive end 72, and the limiting mechanism 20 is located near the limiting end 73. The limiting mechanism 20 includes a second driving member 22 and a limiting block 21. The second driving member 22 drives the limiting block 21 to move closer to or away from the end face of the limiting end 73 of the battery cell 70. When pressing adhesive is required, the first driving member 15 and the second driving member 22 are activated simultaneously, driving the pressing claw 12 and the limiting block 21 to move toward the battery cell 70 until the pressing claw 12 flattens the adhesive tape 71 protruding beyond the adhesive end 72 of the battery cell 70 onto the end face of the adhesive end 72. When pressing the adhesive tape 71, the limiting block 21 abuts against the limiting end 73 of the battery cell 70, and the pressing claw 12 abuts against the adhesive end 72 of the battery cell 70, forming a structure that relatively clamps the battery cell 70, so that the position of the battery cell 70 remains stable during the pressing process, which is beneficial to improving the pressing quality.

[0064] In some embodiments, the battery cell pressing system 100 may further include a transfer mechanism 30 disposed between the limiting mechanism 20 and the battery cell pressing mechanism 10. The transfer mechanism 30 includes a third drive member 32 and a pneumatic clamping assembly 31 for gripping the battery cell 70. The pneumatic clamping assembly 31 moves the battery cell 70 under the action of the third drive member 32, aligning the battery cell 70 with the pressing claw 12. In this embodiment, the horizontal plane where the pressing claw 12 and the limiting block 21 are located is higher than the horizontal plane of the battery cell 70 feeding and conveying; the transfer mechanism 30 needs to grip the battery cell 70 until it is aligned with the pressing claw 12. The third drive member 32 in the transfer mechanism 30 is a slide cylinder. The pneumatic clamping assembly 31 includes pneumatic fingers 311 and a transfer clamp 312. Before the adhesive bonding process, when the battery cell 70 reaches the adhesive bonding station, that is, when the battery cell 70 is located between the battery cell adhesive bonding mechanism 10 and the limiting mechanism 20, and below the transfer mechanism 30, the third drive member 32 drives the pneumatic clamping assembly 31 to move downward. Subsequently, the pneumatic finger 311 is activated, controlling the transfer clamp 312 to grip the battery cell 70. After gripping the battery cell 70, the third drive member 32 drives the pneumatic clamping assembly 31 to move upward until the adhesive end 72 of the battery cell 70 is aligned with the adhesive bonding claw 12, so that the battery cell 70 is in a working position where adhesive bonding can be performed, so that the battery cell adhesive bonding mechanism 10 can perform adhesive bonding operation on the battery cell 70.

[0065] In addition, to simplify the structure of the cell bonding system 100, the cell bonding system 100 may also include a fixing plate 40. The fixing plate 40 is disposed opposite to the cell bonding mechanism 10, and the limiting mechanism 20 and the transfer mechanism 30 are both connected to the fixing plate 40.

[0066] In some embodiments, the cell bonding system 100 further includes a positioning and correction mechanism 50, which includes a straightening block 51 for positioning the cell 70. The positioning and correction mechanism 50 is located upstream of the cell bonding mechanism 10 to improve the quality of subsequent bonding. In this embodiment, the positioning and correction mechanism 50 is located at both ends of the cell 70 during loading, i.e., the positioning and correction mechanism 50 is located near the bonding end 72 and the limiting end 73 of the cell 70, respectively. The positioning and correction mechanism 50 includes a fourth driving member 52 and a straightening block 51 connected to the fourth driving member 52. When reaching the previous position of the bonding station, both sets of positioning and correction mechanisms 50 work simultaneously. The fourth driving member 52 drives the straightening block 51 to move towards the cell 70 and make the straightening block 51 abut against the cell 70, thereby correcting the position of the cell 70. It is understood that this is not a limitation on the number, position, and structure of the positioning and correction mechanism 50. For example, in some embodiments, a set of positioning and correction mechanisms 50 may be provided with a plurality of correction top blocks 51, which limit the multiple positions of the battery cell 70 through the plurality of correction top blocks 51.

[0067] In addition, the battery cell bonding system 100 also includes a battery cell loading mechanism 60, with the battery cell bonding mechanism 10 and the limiting mechanism 20 respectively disposed on both sides of the battery cell loading mechanism 60. In this embodiment, the battery cell loading mechanism 60 is a conveyor belt, and the battery cell loading mechanism 60 is provided with a battery cell limiting groove 61. The battery cell limiting groove 61 adopts a horizontally placed structure, that is, when the battery cell 70 is placed on the battery cell limiting groove 61, the line connecting the adhesive end 72 and the limiting end 73 of the battery cell 70 is perpendicular to the conveying path of the battery cell loading mechanism 60 on the horizontal plane.

[0068] The working process of the battery cell bonding mechanism 10 is explained in detail below:

[0069] The battery cell 70 is placed horizontally on the battery cell loading mechanism 60 and transported by the battery cell loading mechanism 60. When the battery cell 70 arrives at the station before the pressing station, the positioning and correction mechanism 50 starts to work. The straightening top block 51 extends towards the battery cell 70 under the action of the fourth driving member 52 and abuts against the end faces of both ends of the battery cell 70, forming a state of relative clamping of the battery cell 70, thereby achieving the purpose of correcting the position of the battery cell 70.

[0070] Subsequently, the top straightener 51 retracts, and the battery cell 70 moves to the adhesive pressing station under the action of the battery cell loading mechanism 60. At this time, the transfer mechanism 30 starts working, and the pneumatic clamping assembly 31 moves downward to approach the battery cell 70 under the action of the third drive component 32; the pneumatic finger 311 is activated, controlling the transfer clamp 312 to clamp the battery cell 70; after the transfer clamp 312 clamps the battery cell 70, the third drive component 32 is activated, causing the pneumatic clamping assembly 31 to move the battery cell 70 upward until the battery cell 70 reaches the position for adhesive pressing; at this time, the adhesive end 72 of the battery cell 70 is aligned with the adhesive pressing claw 12;

[0071] The first driving component 15 and the second driving component 22 are activated simultaneously, driving the pressure claw 12 and the limiting block 21 to move toward the battery cell 70. The limiting block 21 abuts against the limiting end 73 of the battery cell 70, and the adhesive end 72 of the battery cell 70 passes through the guide inlet 131 and enters the guide part 13; the adhesive paper 71 protruding from the end face of the adhesive end 72 of the battery cell 70 moves toward the direction of the center line of the battery cell 70 under the action of the pressure claw 12 to avoid flipping outward, until the adhesive paper 71 abuts against the pressing surface 1212, and the adhesive paper 71 is pressed onto the end face of the adhesive end 72 under the action of the pressing surface 1212;

[0072] After the adhesive tape 71 is pressed onto the end face of the adhesive end 72, the first drive member 15 and the second drive member 22 drive the pressing claw 12 and the limiting block 21 to retract respectively; then, the third drive member 32 is activated, causing the pneumatic clamping assembly 31 to move downward, the transfer clamp 312 to release, and the battery cell 70 is placed back into the battery cell loading mechanism 60.

[0073] The third driving component 32 is activated, causing the pneumatic clamping assembly 31 to retract to its initial position;

[0074] The cell bonding system 100 repeats the above process to continuously bond the cells 70 on the cell feeding mechanism 60.

[0075] Example 3:

[0076] The difference between this embodiment and Embodiment 2 is that this embodiment uses a vertically placed battery cell 70. Another embodiment of the battery cell bonding system 100 will be described below; for similarities, please refer to Embodiment 2.

[0077] The limiting mechanism 20 can be disposed on the cell loading mechanism 60. The limiting mechanism 20 includes a limiting block 21. In this embodiment, the limiting block 21 surrounds a cell limiting groove 61 adapted to the cell 70. The cell limiting groove 61 is a vertically extending cylindrical structure, that is, when the cell is placed in the cell limiting groove 61, the line connecting the adhesive end 72 and the limiting end 73 of the cell 70 is perpendicular to the conveying path of the cell loading mechanism 60 in the vertical plane. The limiting end 73 of the cell 70 is placed in the cell limiting groove 61, and the adhesive end 72 is close to the upper end of the cell limiting groove 61. Correspondingly, the cell pressing mechanism 10 is located above the cell loading mechanism 60, and the first driving member 15 drives the pressing claw 12 to move downward so that the pressing claw 12 can press the adhesive end 72 of the cell 70 located below.

[0078] The above description is merely an example and illustration of the structure of this utility model, and while the description is quite specific and detailed, it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these obvious substitutions all fall within the protection scope of this utility model.
