Description

Technical Field

[0001] This utility model belongs to the field of battery production technology, and specifically relates to a battery coating paper device. Background Technology

[0002] In the manufacturing process of new energy battery packs, adhesive tape is typically applied to the outer surface of the battery to enhance its waterproof, dustproof, and structural strength capabilities. As new energy equipment evolves towards miniaturization and high integration, the structural design of battery packs is becoming increasingly complex. Currently, some adhesive application processes involve specific requirements, necessitating the application of adhesive tape to different surfaces of the battery pack, as well as precise application of tape at varying heights to the central portion of the battery. This places higher demands on the precision and adaptability of the adhesive tape application process. Most battery wrapping devices on the market currently only involve bending and attaching from a single plane to adjacent surfaces, typically achieved using a single roller or bending block. However, this type of device has limitations; it cannot meet the needs of wrapping at different heights or stepped platforms along a certain direction of the battery. Due to the existence of planes at different heights, using a single roller for wrapping may result in tape displacement, tape wrinkling, and other issues, reducing the quality and efficiency of the wrapping.

[0003] Therefore, designing a precise and efficient adhesive application device for situations requiring adhesive application at different horizontal levels has become a key technical problem that urgently needs to be solved in the current battery manufacturing industry. Summary of the Invention

[0004] To address the shortcomings of the prior art, this utility model provides a battery coating paper device. By integrating an upper pressure block, a roller assembly, a first direction motion component, and a second direction motion component, and defining the relative positions of the upper pressure block and the roller assembly, the device achieves partitioned adhesion of the coating paper to different platforms of the battery, resulting in excellent coating effect and high efficiency.

[0005] The technical effects to be achieved by this utility model are realized through the following technical aspects: This utility model provides a battery coating device, wherein the coating includes a first pressure-holding area and a second pressure-holding area, and the battery is provided with a first platform and a second platform that are respectively adhered to the first pressure-holding area and the second pressure-holding area. The first platform and the second platform have a vertical height difference. The battery coating device includes a lower support mechanism and an upper pressure and adhesive roller mechanism. The lower support mechanism includes a lower support drive assembly and a lower support block driven and connected by the lower support drive assembly; The upper pressure adhesive roller mechanism includes a first direction motion component, a second direction motion component and an upper pressure block driven and connected by the first direction motion component. The second direction motion component and the upper pressure block move along the first direction under the driving action of the first direction motion component. The second direction motion component is driven and connected to a roller assembly. The roller assembly is used to roll the first pressure-holding area, and the upper pressure block is used to press the second pressure-holding area; the distance between the roller assembly's rolling contact surface and the upper pressure block's pressing surface is equal to the vertical height difference between the first platform and the second platform.

[0006] In some implementations, the driving direction of the first directional motion component is vertical, and the driving direction of the second directional motion component is horizontal.

[0007] In some implementations, the upper pressure block partially encloses a receiving area, and the roller assembly is initially located in the receiving area; after the upper pressure block is pressed against the second pressure-holding area, the second directional motion component drives the roller assembly to move towards the first pressure-holding area.

[0008] In some implementations, the upper pressure block includes a pressing part and a main body part. The pressing part is a block-shaped structure adapted to the second pressure-holding area, and the thickness of the pressing part is equal to the height difference between the first platform and the second platform.

[0009] In some implementations, a first connecting member is provided between the second directional motion component and the roller assembly, and a first spring is connected to the end of the roller assembly away from the roller pressing, the first spring being connected to the first connecting member.

[0010] In some implementations, the battery coating paper device further includes a coating block mechanism, which includes a coating motion module and a coating block connected to the coating motion module, with the coating end of the coating block facing the coating end of the battery. The adhesive tape also includes a bending area connected to the second pressure-holding area, and the adhesive block is used to bend and press the bending area.

[0011] In some implementations, the adhesive application motion module includes a first direction motion component two and a second direction motion component two connected to each other.

[0012] In some implementations, at the adhesive application end, the adhesive application block includes a guide surface and a pressing surface. The pressing surface is arranged along a vertical plane and is adapted to the front end face of the battery pack end. The guide surface extends from the lower end of the pressing surface in a direction away from the battery pack end to the lower end of the adhesive application block.

[0013] In some implementations, the adhesive application end of the adhesive application block is provided with a buffer.

[0014] In some implementations, the adhesive application block mechanism includes at least two adhesive application blocks, the upper surface of which is a first pressing surface. The first pressing surfaces of different adhesive application blocks have a vertical height difference. The first pressing surface is used to press a portion of the bending area onto the lower surface of the battery pack end.

[0015] In summary, this utility model has at least the following advantages: 1. This utility model provides a battery coating adhesive device. In the battery coating adhesive device, a second-direction motion component is driven and connected to a roller assembly. That is, the roller assembly and the upper pressure block move together under the drive of the first-direction motion component. After the upper pressure block presses against the second pressure-holding area of ​​the adhesive paper, completing the initial adhesion and fixation of the adhesive paper, the roller assembly moves towards the first pressure-holding area under the drive of the second-direction motion component, and completes the adhesion and fixation of the first pressure-holding area and the first platform of the battery, thereby completing the adhesion of the adhesive paper to different platforms. On the one hand, the roller assembly and the upper pressure block are driven by the first-direction motion component, thus greatly simplifying the size of the equipment, which is beneficial for coating small batteries. On the other hand, the initial fixation of the upper pressure block helps to increase the stability of the adhesive paper, and the roller assembly is driven by the second-direction motion component after the upper pressure block has initially achieved initial pressing, thereby completing the bonding between platforms of different heights and the adhesive paper. This battery coating adhesive device not only achieves bonding between platforms of different heights and the adhesive paper, but also has the characteristics of simplified size, high efficiency, and excellent coating effect.

[0022] For ease of understanding, it should be noted that the X-axis in the graph represents the horizontal direction, the Y-axis represents the vertical direction, and the Z-axis represents the vertical direction.

[0023] Example 1: This utility model provides a battery coating paper device, which can achieve bonding of adhesive paper 10 to platforms of different heights, while also taking into account the characteristics of compact size, high efficiency and excellent coating effect.

[0024] Please see Figures 1 to 4 The battery pack adhesive tape device includes a lower support mechanism 100 and an upper pressure adhesive applicator mechanism 200. The lower support mechanism 100 is used to abut against the lower end of the battery to position the lower end of the battery, so as to facilitate the subsequent pressure application and application of pressure to the battery and adhesive tape 10. The upper pressure adhesive applicator mechanism 200 is used to apply pressure to attach the adhesive tape 10 located on the upper surface of the battery.

[0025] It should be noted that the adhesive tape 10 includes a first pressure-holding area 11 and a second pressure-holding area 12. The adhesive tape 10 is initially pre-attached to the battery in the previous process, but complete encapsulation is not achieved. The upper surface of the battery is provided with a first platform and a second platform, which are respectively adhered to the first pressure-holding area 11 and the second pressure-holding area 12. There is a vertical height difference between the first platform and the second platform. In this embodiment, the horizontal height of the second platform is lower than that of the first platform.

[0026] The lower support mechanism 100 includes a lower support drive assembly 110 and a lower support block 120 driven and connected by the lower support drive assembly 110. When the battery with the adhesive tape 10 pre-attached is moved to the coating station, the lower support drive assembly 110 operates, causing the lower support block 120 to move upward until it abuts against the lower end of the battery, thereby positioning the lower end of the battery.

[0027] The upper pressure applicator mechanism 200 includes a base 260 and a first directional motion component 210 disposed on the base 260. The first directional motion component 210 is driven by a second directional motion component 220 and an upper pressure block 230. The second directional motion component 220 and the upper pressure block 230 are jointly driven by the first directional motion component 210. In this embodiment, the movement direction of the first directional motion component 210 is vertical, and the movement direction of the second directional motion component 220 is horizontal. Preferably, the horizontal direction here refers to the direction from the second platform to the first platform.

[0028] During operation, the second directional motion component 220 and the upper pressure block 230 move vertically downwards under the driving action of the first directional motion component 210 until the upper pressure block 230 presses onto the second pressure-holding area 12 of the adhesive tape 10, thus completing the adhesion and fixation of the second pressure-holding area 12 to the second platform of the battery. Preliminary fixation of the adhesive tape 10 facilitates subsequent processes while ensuring the stability of the adhesive tape 10's position.

[0029] The second directional motion component 220 is connected to the roller assembly 240. The distance between the roller assembly 240's pressing contact surface and the pressing surface of the upper pressure block 230 is equal to the vertical height difference between the first platform and the second platform. After the upper pressure block 230 completes pressing the second pressure-holding area 12, the roller assembly 240 moves laterally under the drive of the second directional motion component 220 and directly rolls the first pressure-holding area 11, achieving adhesion between the first pressure-holding area 11 and the first platform.

[0030] The roller assembly 240 and the upper pressure block 230 are jointly driven by the first direction motion assembly 210, which helps to simplify the structure of the battery coating paper device and facilitates the coating operation for small batteries. This battery coating paper device can achieve the adhesion of adhesive paper 10 to platforms of different heights, while also being compact, efficient, and providing excellent coating effect.

[0031] Example 2: This embodiment makes further structural optimizations based on Embodiment 1. Please refer to Embodiment 1 for details. Figures 5 to 6 .

[0032] In this embodiment, to ensure that the roller assembly 240 can fully roll over the first pressure-holding zone 11, the upper pressure block 230 partially encloses and forms a receiving area 231. Specifically, the upper pressure block 230 includes a pressing part 232 and a main body part 233, which are block-shaped and connected in an "L" shape. In this embodiment, the pressing part 232 and the main body part 233 partially enclose and form the receiving area 231 on the side where the first platform is located. In the initial state, the roller assembly 240 is located in the receiving area 231. When the upper pressure block 230 presses against the second pressure-holding zone 12, the second direction movement component 220 drives the roller assembly 240 to move from the receiving area 231 toward the first pressure-holding zone 11. The receiving area 231 provides clearance space for the roller assembly 240 in the initial state, which is beneficial for achieving sufficient rolling over the first pressure-holding zone 11.

[0033] Preferably, the thickness of the pressing part 232 is equal to the height difference between the first platform and the second platform, and the upper surface of the pressing part 232, that is, the upper surface near the receiving area 231, is flush with the first platform. Therefore, the upper surface of the pressing part 232 can provide a preliminary guiding effect for the roller assembly 240, realizing the transition of rolling the first pressure holding area 11.

[0034] A first connector 250 is provided between the second directional motion component 220 and the roller assembly 240. The first connector 250 is used to connect the roller assembly 240 and the second directional motion component 220. A first spring 251 is connected to the end of the roller assembly 240 away from the rolling pressure, and the first spring 251 is connected to the first connector 250. During the rolling process, the roller assembly 240 is subjected to the reaction force of the battery. At this time, the first spring 251 undergoes elastic deformation, providing space for displacement of the roller assembly 240. At the same time, it uses a buffering effect to prevent the roller assembly 240 from damaging the adhesive paper 10 due to high rolling pressure during the rolling process.

[0035] Example 3: This embodiment makes further structural optimizations based on embodiment 2. Please refer to embodiment 2 for further details. Figures 7 to 10 .

[0036] A battery coating paper device further includes a coating block mechanism 300, which includes a coating motion module 310 and a coating block 320 connected to the coating motion module 310. The coating end of the coating block 320 faces the coating end of the battery. The coating paper 10 includes a bending area 13 in addition to the first pressure-holding area 11 and the second pressure-holding area 12. During the coating paper 10 operation, the bending area 13 needs to be bent and pressed from the upper surface of the battery until the bending area 13 is attached to the front and lower surfaces where the battery coating end is located.

[0037] During operation, the adhesive application block 320 is driven by the adhesive application motion module 310 to press and fold the bending area 13 of the adhesive paper 10 from top to bottom, and press the bending area 13 with the end face of the battery pack adhesive end, thereby realizing the bending and pasting of the bending area 13.

[0038] It should be noted that the adhesive application module 310 includes a first-direction motion component 311 and a second-direction motion component 312 connected to each other. In this embodiment, the first-direction motion component 311 is driven and connected by the second-direction motion component 312, and the adhesive application block 320 is driven and connected by the first-direction motion component 311. The first direction refers to the vertical direction, and the second direction is along the direction where the front and rear ends of the battery are located, or in other words, along the direction of the line connecting the battery's adhesive end to its opposite end. Under normal conditions, the adhesive application block 320 is away from the battery. When operation is required, the second-direction motion component 312 moves, driving the first-direction motion component 311 and the adhesive application block 320 closer to the adhesive end of the battery, until the adhesive application end of the adhesive application block 320 is above the bending area 13. Then, the first-direction motion component 311 operates, driving the adhesive application block 320 to move vertically downward, pressing the bending area 13 against the end face of the front end of the battery while bending the bending area 13.

[0039] Preferably, to reduce damage to the adhesive tape 10 during the application of adhesive by the adhesive applicator 320 and to ensure accurate bending and pressing of the adhesive tape 10 onto the battery, the adhesive applicator 320 is provided with a guide surface 321 and a pressing surface 322 at the application end. The pressing surface 322 is above the guide surface 321 and is parallel to the surface to be bonded at the front end of the battery. The guide surface 321 extends from its lower end along a direction away from the battery's adhesive application end to the lower end of the adhesive applicator 320.

[0040] Meanwhile, the upper surface of the adhesive block is the first adhesive pressing surface 324, and the lower surface is the second adhesive pressing surface 325. In this embodiment, both the first and second adhesive surfaces extend along a horizontal plane.

[0041] During operation, the adhesive block 320 moves from top to bottom relative to the adhesive tape 10. Initially, the second pressing surface 325 first abuts against the bending area 13. Then, the adhesive block 320 moves downward and backward, so that the guide surface 321 acts on the bending area 13 to achieve the initial bending of the bending area 13, until the pressing surface 322 abuts against the front end of the battery pack. At this time, the adhesive block 320 moves downward so that part of the bending area 13 is attached to the front end of the battery. After the front end of the battery is wrapped, the adhesive block 320 moves towards the battery pack end, so that the first pressing surface 324 presses part of the adhesive tape onto the lower surface of the battery pack end to complete the overall wrapping process.

[0042] It should be noted that the inclined guide surface 321 is close to and bends the bending area 13 of the adhesive tape 10, which effectively avoids damage to the adhesive tape 10 during the bending process caused by the sharp edges of the conventional cuboid adhesive block 320.

[0043] In particular, the adhesive application end of the adhesive application block 320 is evenly covered with a buffer 323, which can be a buffer silicone, to help further prevent damage to the adhesive tape 10.

[0044] In addition, the adhesive application block 320 is movably connected to the second directional motion component 312 via the first directional motion component 311. A second connecting member 330 is provided between the first directional motion component 311 and the adhesive application block 320, and a second spring 331 is provided between the end of the adhesive application block 320 away from the adhesive application and the second connecting member 330. The second spring 331 utilizes the characteristics of elastic deformation to improve the cushioning effect on the adhesive application block 320, reduce damage to the adhesive tape 10, and help reduce costs caused by wear and tear.

[0045] It should be noted that a slider may also be provided between the adhesive application block 320 and the second spring 331. The adhesive application block 320 is fixedly connected to the slider, the slider is slidably connected to the second connecting member 330, and the end of the slider away from the adhesive application block 320 is connected to the second connecting member 330 through the second spring 331. The slider and the second spring 331 cooperate to achieve a buffering effect.

[0046] Furthermore, in this embodiment, the adhesive tape 10 includes two bending areas 13. When the two bending areas 13 are wrapped around the battery, the different bending areas 13 below the battery are located on different horizontal planes.

[0047] Accordingly, the adhesive application block mechanism 300 includes two parallel adhesive application blocks 320. The first pressing surfaces 324 of the different adhesive application blocks 320 have a height difference in the vertical direction to adapt to the positional relationship between the different bending areas 13 and the battery.

[0048] The above description is merely an example and illustration of the structure of this invention, and while the description is specific and detailed, it should not be construed as limiting the scope of this invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these obvious substitutions all fall within the protection scope of this invention.
