Description

Technical Field

[0001] This utility model belongs to the technical field of battery cell production equipment, specifically a device for applying insulating tape to battery cells. Background Technology

[0002] The mainstream battery cells are lithium-ion cells, with common types including lithium iron phosphate and ternary lithium. Lithium iron phosphate has high safety and long cycle life, and is mostly used in energy storage and commercial vehicles. Ternary lithium has higher energy density and is widely used in passenger cars, mobile phones and other consumer electronics. It is a core energy storage component in the new energy field.

[0003] The existing battery cell assembly equipment has the following drawbacks: In order to ensure the insulation performance of the electrode tabs, insulating tape needs to be initially pasted on the electrode tabs. However, the existing equipment can only paste the insulating tape on the electrode tabs and cannot continue to fold and wrap the insulating tape around the electrode tabs. The subsequent folding, pressing and pasting still needs to be done manually, which is time-consuming, labor-intensive and costly. Therefore, in order to solve the above problems, a battery cell insulating tape pasting equipment is proposed. Utility Model Content

The insulating tape applicator station is used to place the insulating tape on the bonding position of the battery cell, and the tape wrapping station is used to fold and wrap the insulating tape pasted on the battery cell. The dividing plate is provided with a vacuum assembly carrier that cooperates with the above-mentioned stations. The tape wrapping station includes a folding mechanism, and the folding mechanism is provided with rollers. The rollers are driven by a driving device to roll along the top of the battery cell towards the side wall of the electrode end of the battery cell.

[0006] Preferably, the folding mechanism includes a movable seat driven by a driving device. The roller is mounted on one side of the movable seat. The driving device for moving the movable seat is a first driving cylinder and a second driving cylinder, which can drive the movable seat to move up, down, left, and right. The second driving cylinder is mounted on the working end of the first driving cylinder, and the movable seat is mounted on the working end of the second driving cylinder. A platform is slidably mounted on the movable seat. One side of the platform is connected to the movable seat via a guide rod and a spring. A connecting rod for mounting the roller is slidably mounted on one side of the platform. One side of the connecting rod is connected to the platform via a guide rod and a spring.

[0007] Preferably, the coating station further includes a pressing mechanism to press the battery cell to prevent it from lifting up, the pressing mechanism including an elastic pressure block that acts on the top of the battery cell by a driving device.

[0008] Preferably, the insulating tape application station includes a support, a feeding tray, and a receiving tray. The support is equipped with a material picking platform.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-6 The present invention discloses a device for applying insulating tape to a battery cell, comprising a frame, an indexing plate 1 on the frame, and an insulating tape application station 2, a pressing station 3, and a tape wrapping station 4 arranged sequentially on the frame in the rotation direction of the indexing plate 1. The insulating tape application station 2 is used to place the insulating tape 02 on the pasting position of the battery cell 01. The tape wrapping station 4 is used to fold and wrap the insulating tape 02 pasted on the battery cell 01. The indexing plate 1 is provided with a vacuum assembly carrier 5 that cooperates with the above stations. The tape wrapping station 4 includes a folding mechanism 401, and a roller 4012 is provided on the folding mechanism 401. The roller 4012 is driven by a driving device to roll along the top 011 of the battery cell 01 toward the side wall 012 of the electrode end of the battery cell 01.

[0025] The folding mechanism 401 includes a movable seat 4011 driven by a driving device. A roller 4012 is mounted on one side of the movable seat 4011. The driving device for moving the movable seat 4011 consists of a first driving cylinder 6 and a second driving cylinder 7, which can drive the movable seat 4011 to move up, down, left, and right. The second driving cylinder 7 is mounted on the working end of the first driving cylinder 6, and the movable seat 4011 is mounted on the working end of the second driving cylinder 7. A platform 4013 is slidably mounted on the movable seat 4011. One side of the platform 4013 is connected to the movable seat 4011 via a guide rod and a spring. A roller for mounting is slidably mounted on one side of the platform 4013. The connecting rod 4014 of 4012 is connected to the end of the platform 4013 via a guide rod and a spring on one side. The adhesive coating station 4 also includes a pressing mechanism 402 to press the battery cell 01 to prevent it from tilting. The pressing mechanism 402 includes an elastic pressure block 4021 driven by a drive device to act on the top of the battery cell 01. During operation, when the battery cell 01, which has passed through the insulating tape application station 2, rotates with the indexing plate 1 to the adhesive coating station 4, the drive device of the pressing mechanism 402 first drives the elastic pressure block 4021 to move downward. The elastic pressure block 4021 acts on the top side of the battery cell 01, using its elastic properties to apply appropriate pressure to the battery cell 01, firmly pressing the battery cell 01 and preventing it from tilting. To prevent lifting during the subsequent adhesive wrapping process, the folding mechanism 401 then begins operation. The first drive cylinder 6 and the second drive cylinder 7 work in tandem. The first drive cylinder 6 primarily controls the up-and-down movement of the moving base 4011, while the second drive cylinder 7 primarily controls the left-and-right movement of the moving base 4011. Under their combined action, the moving base 4011 drives the roller 4012 to the top 011 of the battery cell 01, bringing the roller 4012 into contact with the insulating adhesive paper 02 on the battery cell. The roller 4012 is made of rubber. Then, under the continuous drive of the driving device, the roller 4012 rolls along the top 011 of the battery cell 01 towards the side wall 012 of the electrode tab end of the battery cell 01. During the rolling process... In this process, the platform 4013 is elastically connected to the movable seat 4011 through the guide rod and spring, and the connecting rod 4014 is elastically connected to the platform 4013 through the guide rod and spring. It can adaptively adjust according to the shape and undulation of the surface of the battery cell 01, ensuring that the roller 4012 always applies appropriate pressure to the insulating tape 02, so that the insulating tape 02 is folded and wrapped smoothly and tightly on the side wall 012 of the electrode end of the battery cell 01. During this process, the vacuum assembly carrier 5 continues to play a role. It is connected to the external negative pressure tank through the air pipe and uses vacuum adsorption force to help fix the battery cell 01, prevent the battery cell from shifting under the force of the roller, and ensure the accuracy of the adhesive wrapping operation.This invention, through the combination of the above-described structures, can adapt to subtle differences on the surface of the battery cell, ensuring precise folding and wrapping of the insulating tape 02, improving the consistency and pass rate of the adhesive application. Furthermore, the flexible connection structure allows the roller 4012 to have a certain buffering and adjustment capability during operation, not only adapting to the multi-step adhesive application requirements of the battery cell 01 but also reducing adhesive application defects caused by dimensional deviations of the battery cell 01, thus improving the versatility of the equipment.

[0026] Furthermore, the insulating tape application station 2 includes a support 201, a feeding tray 202, and a receiving tray 203. A material-grabbing platform 204 is provided on the support 201. The tape 03 on the feeding tray 202 passes around the rotating roller 205 on the support 201 and the material-grabbing platform 204 before being retrieved by the receiving tray 203. A gripping mechanism 206 is provided on one side of the support 201 to grip the insulating tape 02 on the material tape 03 on the material-grabbing platform 204 and place it at the cell 01 bonding position on the vacuum assembly carrier 5. The gripping mechanism 206 includes a suction cup 2061 driven by a drive device. The end of the material-grabbing platform 204 located in the direction of tape 03 movement is at an acute angle to facilitate the removal of the insulating tape 02 from the tape 03. During operation, the feeding tray 202 first releases the insulating tape tape 03, which is then smoothly conveyed to the vacuum assembly carrier 5 under the guidance of the rotating roller 205. When the material strip 03 reaches the acute angle end of the material strip 03's movement direction on the material picking platform 204, due to the special structure of the acute angle, the material strip 03 undergoes an angle change at this point, which weakens the connection between the insulating adhesive paper 02 on the material strip 03 and the material strip 03. At the same time, the drive device of the gripping mechanism 206 drives the suction cup 2061 to move above the material picking platform 204. The suction cup 2061 adsorbs the insulating adhesive paper 02 on the material picking platform 204 by generating a vacuum negative pressure. Then, the drive device moves again, driving the suction cup 2061 with the adsorbed insulating adhesive paper 02 to move above the pasting position of the battery cell 01 on the vacuum assembly carrier 5. Then, the suction cup 2061 releases the vacuum and places the insulating adhesive paper 02 on the pasting position of the battery cell 01. At the same time, the receiving tray 203 continues to rotate to collect the used waste material strip 03, so that the material strip 03 is always kept taut.

[0027] Furthermore, the pressing station 3 is located between the insulating tape application station 2 and the adhesive wrapping station 4, and is used to initially press the insulating tape 02 applied to the battery cell 01. The pressing station 3 includes a pressing block 301 driven by a driving device. During operation, when the battery cell 01 moves from the insulating tape application station 2 to the pressing station 3 along with the indexing plate 1, the pressing station 3 begins to work, and the driving device drives the pressing block 301 to move downward (in this utility model, the driving device is a cylinder, but not limited to a cylinder), so that the pressing block 301... 01 contacts the insulating tape 02 on the battery cell 01, and then the pressing block 301 applies appropriate pressure to the insulating tape 02. The pressing block 301 is equipped with a pressure sensor that can detect the pressure in real time. The insulating tape 02 is initially attached to the surface of the battery cell 01, so that the insulating tape 02 is initially adhered to the tab on the battery cell 01. After pressing, the drive device drives the pressing block 301 to reset upward and leave the battery cell 01. The battery cell 01 then continues to move with the indexing plate 1 to the adhesive wrapping station 4 for the next step of processing.
