Description

Technical Field

[0001] This utility model belongs to the field of battery technology, specifically relating to a battery adhesive paper shaping device. Background Technology

[0002] With the development of new energy, batteries, as a green, reusable and large-capacity energy storage device, have become a core component driving the new energy revolution and are widely used in new energy vehicles, portable electronic devices, energy storage systems and other fields.

[0003] In battery manufacturing, the adhesive tape shaping process is a crucial step in ensuring product performance and safety. The adhesive tape on the battery head plays a vital role in isolating the tabs from the casing and preventing short circuits. If the tape is warped, bulging, or misaligned, it may cause accidental contact between the tabs and external conductors, leading to safety hazards such as short circuits, overheating, or even fire. Therefore, the flatness of the adhesive tape is a prerequisite for the smooth progress of subsequent processes. If the tape is warped or has irregular edges, it may cause interference between different components during subsequent battery assembly. However, since the battery head also contains many core battery-related structures, such as protection boards or tab structures, excessive shaping pressure must be avoided during the shaping process to prevent adverse effects on the structure. In addition, battery head adhesive tape shaping usually involves bending and attaching the tape to the sides, which places high precision requirements on automated shaping processes.

[0004] Therefore, it is evident that providing a device that can both shape the adhesive tape and protect other structures at the battery head from excessive pressure has become a critical technical problem that urgently needs to be solved. Summary of the Invention

[0038] 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.

[0039] Example 1:

[0040] Please see Figures 1 to 6 This embodiment provides a battery adhesive tape shaping device, which can complete the bending and pressure holding of the adhesive tape, and ensure the quality of the battery during the shaping process.

[0041] Specifically, the battery adhesive tape shaping equipment includes an adhesive application mechanism 100 and a pressure holding mechanism 200. For example... Figures 1 to 3 As shown, the adhesive application mechanism 100 includes a first pressure block 110 for abutting against a first side of the battery and a side application pressure block 120 for abutting against a second side of the battery to bend the adhesive tape. The first and second sides are adjacent, and the first pressure block 110 and the side application pressure block 120 partially enclose a battery placement area. In this embodiment, the first side refers to the surface where the upper end of the battery is located, and the second side is the right side of the battery. It should be noted that the adhesive tape is initially attached to the first side, but not completely flat against the battery surface, and the adhesive tape is generally parallel to the first side, with the right side protruding from the battery. The protruding portion of the adhesive tape will be pressed onto the second side in subsequent operations. In the adhesive application mechanism 100, the lower end of the first pressure block 110 abuts against the first side of the battery, and the upper end is sequentially connected to a first pressure sensor 111 and a first buffer structure 112. The first buffer structure 112 includes a spring, one end of which is connected to the first pressure block 110, and the other end is fixedly connected to a mounting base.

[0042] When the adhesive applicator 100 is operating, the first pressure-holding block 110 applies pressure to the adhesive tape and the first side of the battery. The first pressure sensor 111 measures the applied pressure in real time, enabling real-time monitoring and recording of the pressure. Simultaneously, as the working pressure of the first pressure-holding block 110 increases, the spring in the first buffer structure 112 undergoes elastic deformation, providing a buffer for the operation of the first pressure-holding block 110 and adjusting the pressure accordingly. This ensures that the adhesive tape is adhered to the first side while preventing damage to the battery surface due to excessive pressure.

[0043] As the first side of the battery approaches and abuts against the first pressure block 110, the side-applying pressure block 120 gradually approaches and abuts against the second side of the battery. During this process, the side-applying pressure block 120 bends the adhesive tape protruding from the right side of the battery.

[0044] To protect the battery structure, the side-applying pressure block 120 is connected to a third buffer structure 123 in a first direction and a fourth buffer structure 124 in a second direction. The first direction is the vertical direction, and the second direction is the direction of the second side surface and its opposite side. Both the third buffer structure 123 and the fourth buffer structure 124 include spring elements. When the side-applying pressure block 120 acts on the second side surface, the third buffer structure 123 and the fourth buffer structure 124 can elastically deform to provide buffering in different directions, preventing damage to the adhesive tape and battery surface due to excessive or uneven pressure. It should be noted that in other embodiments, the third buffer structure 123 and the fourth buffer structure 124 can also be other structures with buffering functions.

[0045] In this embodiment, the adhesive application mechanism 100 further includes a first mounting plate 140. A first pressure holding block 110, a first pressure sensor 111, a first buffer structure 112, and a side application pressure block 120 are all integrated and connected to the first mounting plate 140. The first mounting plate 140 is also connected to a first motion module 130. The drive end of the first motion module 130 moves to drive the first pressure holding block 110 and the side application pressure block 120 to move. In this embodiment, the first motion module 130 is the robotic arm body of a 4-axis robot. During operation, the first motion module 130 drives the first pressure holding block 110 and the side application pressure block 120 to move vertically downwards to press the adhesive paper, achieving adhesion between the adhesive paper and the first side surface, and partially bending the adhesive paper towards the second side surface.

[0046] After the adhesive application mechanism 100 initially presses and bends the adhesive tape, the pressure holding mechanism 200 further presses the adhesive tape, especially ensuring that the adhesive tape is completely attached to the second side of the battery. For details, please refer to [link / reference needed]. Figures 4 to 6 The pressure-holding mechanism 200 is located downstream of the adhesive application mechanism 100 and includes a second pressure-holding block 210 for abutting against the first side and a side pressure-holding block 220 for abutting against the second side to press the adhesive paper. Similar to the first pressure-holding block 110, the lower end of the second pressure-holding block 210 abuts against the first side of the battery, and the upper end is sequentially connected to a second pressure sensor 211 and a second buffer structure 212. The side pressure-holding block 220 is used to press the adhesive paper bent towards the second side onto the second side of the battery. In particular, the side pressure-holding block 220 is connected to a first driving assembly 221, and the side pressure-holding block 220 has a side pressure-holding surface 222 parallel to the second side. The first driving assembly 221 drives the side pressure-holding block 220 so that the side pressure-holding surface 222 abuts against the second side, thereby completing the adhesion between the adhesive paper and the second side.

[0047] In this embodiment, the pressure-holding mechanism 200 further includes a second mounting plate 240. The second pressure-holding block 210, the second pressure sensor 211, the second buffer structure 212, the side pressure-holding block 220, and the first drive assembly 221 are all integrated and connected to the second mounting plate 240. The second mounting plate 240 is also connected to a second motion module 230. The drive end of the second motion module 230 moves to drive the second pressure-holding block 210 and the side pressure-holding block 220 to move. In this embodiment, the second motion module 230 is the robotic arm body of a 4-axis robot. During operation, the second motion module 230 drives the second pressure-holding block 210 and the side pressure-holding block 220 to move vertically downwards.

[0048] Similar to the first pressure-holding block 110, the second pressure-holding block 210 applies pressure to the first side of the battery. The second pressure sensor 211 measures and records the applied pressure in real time. As the pressure applied by the second pressure-holding block 210 increases, the spring in the second buffer structure 212 undergoes elastic deformation, providing a buffer for the operation of the second pressure-holding block 210 and thus adjusting the pressure. This ensures that the adhesive tape is adhered to the first side while preventing excessive pressure from damaging the battery surface. In addition, it also helps to position the battery.

[0049] The first drive assembly 221 is a slanted servo cylinder. When the second pressure block 210 acts on the first side of the battery, the drive end of the first drive assembly 221 extends, so that the side pressure surface 222 of the side pressure block 220 acts on the adhesive paper and abuts the adhesive paper to the second side, thus completing the adhesion of the adhesive paper to the second side.

[0050] Furthermore, since the side pressure block 220 needs to apply pressure to the second side of the adhesive tape and the battery, a fifth buffer structure 225 is provided between the side pressure block 220 and the first drive assembly 221. The fifth buffer structure 225 may include a spring. In this embodiment, the first drive assembly 221 is a slanted insertion servo cylinder. The spring of the fifth buffer structure 225 is arranged along the working direction of the slanted insertion servo cylinder. Through elastic deformation, it provides a buffering effect to the side pressure block 220, adjusting the pressure applied to the battery in a timely manner to avoid damaging the adhesive tape and the battery surface.

[0051] Correspondingly, a third pressure sensor 226 may also be provided between the side pressure holding block 220 and the first drive assembly 221 to monitor and collect the pressure of the side pressure holding block 220 in real time, and to facilitate the adjustment of the pressure.

[0052] Example 2:

[0053] This embodiment optimizes the battery adhesive tape shaping equipment based on Embodiment 1. Please refer to Embodiment 1 for further details. Figure 7 The differences are explained below.

[0054] In the adhesive application mechanism 100, the main function of the side application pressure block 120 is to bend the adhesive tape. Therefore, the side application pressure block 120 is provided with a bending portion 121 for abutting against the second side or the corner between the first and second sides, and the bending portion 121 is also connected to a relief surface 122. The relief surface 122 is located below the bending portion 121. The relief surface 122 is formed inclined from the bending portion 121 in a direction away from the second side, and faces the second side but is away from the second side.

[0055] Preferably, the bending portion 121 has an arc-shaped structure. Compared with the linear contact between the bending portion 121 and the battery, the arc-shaped bending portion 121 has a buffering effect, which can reduce the possibility of scratching the adhesive paper while bending it, thereby reducing the defect rate of the adhesive paper shaping.

[0056] In particular, since the head of the battery, i.e. the first side of this application, is usually provided with tabs or other battery structures, in order to avoid damaging the battery during the shaping of the adhesive tape, and also to ensure that the adhesive tape can be tightly attached to the first side, the lower end face of the first pressure block 110 may also be provided with a clearance step 101 that is adapted to the first side.

[0057] Example 3:

[0058] This embodiment optimizes the battery adhesive tape shaping equipment based on Embodiment 2. Please refer to Embodiment 2 for further details. Figure 8 The differences are explained below.

[0059] The side pressure block 220 has a coating 223 on the side pressure surface 222. The coating 223 can be silicone or other materials with soft or cushioning properties to prevent the side pressure block 220 from damaging the adhesive paper and the second side of the battery.

[0060] In addition, the side pressure block 220 is also provided with a transition pressure surface 224 connected to the side pressure surface 222. The transition pressure surface 224 is used to abut against the corner between the first side and the second side of the battery. Specifically, the shape of the transition pressure surface 224 is adapted to the corner. In this embodiment, the transition pressure surface 224 is an arc-shaped surface to ensure that the adhesive tape is completely adhered to the battery surface, and an adhesive wrap 223 is also provided at the transition pressure surface 224.

[0061] In particular, since the head of the battery, i.e. the first side of this application, is usually provided with tabs or other battery structures, in order to avoid damaging the battery during the shaping of the adhesive tape, and also to ensure that the adhesive tape can be tightly attached to the first side, the lower end face of the second pressure block 210 may also be provided with a clearance step 101 that is adapted to the first side.

[0062] 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.
