Description
Technical Field
[0001] This utility model relates to the field of battery packaging technology, specifically to a battery adhesive paper pressing device. Background Technology
[0002] Batteries, as crucial energy storage devices in modern technological development, play an indispensable role in numerous fields, from portable electronic devices to electric vehicles and renewable energy storage systems. Their performance and quality significantly impact the reliability and safety of related products, making high-quality battery production a critical mission for the battery manufacturing industry. In the battery production process, the encapsulation stage is extremely important. By wrapping certain parts of the battery's surface with adhesive tape, the internal structure of the battery is protected, thereby ensuring its safety and stability.
[0003] Currently, battery encapsulation primarily utilizes roller-wrapping adhesive tape technology. This technology uses the back-and-forth movement and simultaneous rotation of the rollers to press the adhesive tape onto the battery surface. However, this technology has several drawbacks. Uneven surfaces on the battery can interfere with the smooth adhesion of the adhesive tape, leading to wrinkles. If the wrapping roller is too long, its parallelism may be insufficient, resulting in uneven force on the tape and gaps between the tape and the battery surface. Furthermore, insufficient roundness of the wrapping roller can cause air bubbles to form between the tape and the battery. These problems—wrinkles, gaps, and air bubbles—directly reduce battery yield, significantly increase production costs, and waste resources. Therefore, existing battery encapsulation technology urgently needs improvement. Utility Model Content

[0016] The beneficial effects of this utility model are:
[0017] This utility model discloses a battery adhesive tape pressing device. First, compared to existing roller pressing methods, it fully utilizes the advantages of dense and soft brushes, highly simulating human hand pressure control to precisely wrap and press the battery's uneven surfaces. This effectively eliminates the possibility of wrinkles, voids, and air bubbles caused by slight height differences on the battery surface during the pressing process, significantly improving the yield rate of battery encapsulation adhesive tape. This not only drastically reduces production costs but also minimizes unnecessary resource waste. Second, by setting a brush force adjustment module, the pressure of the first brush on the adhesive tape can be precisely adjusted according to actual needs, ensuring a tighter and more uniform adhesion between the adhesive tape and the battery, further improving the pressing quality. Finally, when the second brush encounters a protrusion during operation, a second elastic element allows the lifting slide to move elastically, achieving elastic wrapping of the adhesive tape, greatly improving the wrapping effect and making the battery adhesive tape wrapping more secure and reliable.

Detailed Implementation
[0028] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. Identical components are indicated by the same reference numerals.
[0029] Please see Figures 1 to 8This utility model provides a battery adhesive tape pressing device, which includes an adhesive tape side wrapping pressing mechanism 10 and an adhesive tape bottom wrapping pressing mechanism 20. The adhesive tape side wrapping pressing mechanism 10 is used to press the adhesive tape 40 extending from the bottom surface of the battery 30 onto the side surface of the battery 30, and the adhesive tape bottom wrapping pressing mechanism 20 is used to press the adhesive tape 40 that has been side-wrapped and extends downward onto the bottom surface of the battery 30, thereby achieving the wrapping of the side wall and bottom wall of the battery 30 with adhesive tape 40.
[0030] like Figures 1 to 3 As shown, the adhesive tape side wrapping and pressing mechanism 10 includes a first support 100, a brush force adjustment module, and a first brush 120. The first support 100 is fixed on the battery 30 packaging production line and has a square frame structure. The first support 100 has a first through hole 101 for lifting the battery 30. The shape of the first through hole 101 is close to the shape of the battery 30. There are multiple brush force adjustment modules, which are fixed around the first through hole 101 on the first support 100. Each brush force adjustment module is fixed with a first brush 120 located on the side of the first through hole 101. Specifically, the shape of the battery 30 is composed of multiple rectangles. Therefore, the multiple brush force adjustment modules are distributed around the first through hole 101.
[0031] like Figures 4 to 8 As shown, the adhesive tape bottom wrapping and pressing mechanism 20 includes a second bracket 200, a pushing cylinder 210, a connecting module, and a second brush 230. The second bracket 200 is fixed on the battery 30 packaging production line and is also a square frame structure. The second bracket 200 has a second through hole 201 for the battery 30 to pass through, and its shape is consistent with the first through hole 101. A battery carrier 202 is fixed inside the second bracket 200 and directly below the second through hole 201. The battery carrier 202 is fixed on the production line. There are multiple pushing cylinders 210, which are fixed on the second bracket 200 around the second through hole 201. A connecting module is fixed at the telescopic end of each pushing cylinder 210. Each connecting module has at least one second brush 230 located on the side of the second through hole 201. Each second brush 230 moves away from / presses the adhesive tape 40 on the bottom surface of the battery 30 as the telescopic end of the pushing cylinder 210 extends and retracts.
[0032] This utility model's battery adhesive tape pressing device utilizes a robotic arm to move a battery 30, with adhesive tape 40 already wrapped around its top surface and the edge of the tape extending beyond the edge of the battery 30, to above the first through hole 101. Then, the battery 30 is slowly moved downwards, and the brushing force of the first brush 120 presses the adhesive tape 40 extending from the top surface of the battery 30 against the side wall of the battery 30. After the side wall of the battery 30 is wrapped and pressed by the adhesive tape 40, the robotic arm again transfers the battery 30 to the battery carrier 202. The extension and retraction of the push cylinder 210 drives the second brush 230 to reciprocate, pressing the adhesive tape 40 against the bottom surface of the battery 30, thus achieving the wrapping of the side wall and bottom surface of the battery 30 with adhesive tape 40. It should be noted that the side wall and bottom surface of the battery 30 are not completely wrapped; therefore, the number and placement of the first brush 120 and the second brush 230 are determined by the wrapping position of the battery 30.
[0033] This utility model discloses a battery adhesive tape pressing device. First, compared to existing roller pressing methods, it utilizes the dense and soft characteristics of brushes to simulate the pressure controlled by a human hand. The brushes press and seal the uneven surfaces of the battery, effectively avoiding problems such as wrinkles, voids, and air bubbles that occur during adhesive tape pressing due to small height differences on the battery surface. This significantly improves the yield rate of battery encapsulation adhesive tape, reduces production costs, and minimizes resource waste. Second, by setting up a brush force adjustment module, the pressure of the first brush on the adhesive tape 40 can be precisely adjusted according to actual needs, further improving the pressing quality.
[0034] like Figure 2 and Figure 3As shown, the brush force adjustment module includes a first guide rail 111, a horizontal sliding assembly 112, an adjusting screw 115, and a first elastic element 116. The first guide rail 111 is fixedly mounted on the first bracket 100 near the first through hole 101 along the length / width direction of the first bracket 100. A first limiting seat 113 is fixedly mounted at the end of the first guide rail 111 near the first through hole 101. Specifically, the first limiting seat 113 is assembled on the first bracket 100 by screws. The first guide rail 111 is located away from the first through hole 101. An adjusting screw seat 114 is fixedly provided at the end of the hole 101. Specifically, the adjusting screw seat 114 is assembled onto the first bracket 100 by screws. The horizontal sliding assembly 112 is slidably disposed on the first guide rail 111. The horizontal sliding assembly 112 includes a first slide block 1121, a connecting plate 1122, and a mounting base 1123. The first slide block 1121 is slidably disposed on the first guide rail 111, so that the first slide block 1121 can slide between the adjusting screw seat 114 and the first limiting seat 113. The same brush force adjustment... The module includes at least two parallel first guide rails 111, with first slide blocks 1121 corresponding to each first guide rail 111. A connecting plate 1122 connects the two first slide blocks 1121 into one unit. A mounting base 1123 is assembled onto the connecting plate 1122 by screws. The horizontal sliding assembly 112 has an adjusting hole 1124 coaxial with the screw hole of the adjusting screw seat 114 on its side wall away from the first through hole 101. Specifically, the adjusting hole 1124 is formed on the connecting plate 1122, and the adjusting screw... The screw of rod 115 is screwed through the screw hole of adjusting screw seat 114 and pushed into adjusting hole 1124. The screw part of adjusting screw 115 is fitted with a first elastic element 116. One end of the first elastic element 116 abuts against the thick rod body of adjusting screw 115, and the other end of the first elastic element 116 is inserted into adjusting hole 1124. The elasticity of the first elastic element 116 is changed by rotating adjusting screw 115. The first brush 120 is fixed at the position of horizontal sliding assembly 112 near the first through hole 101.
[0035] In an embodiment of this invention, the first brush 120 comprises nylon-like bristles arranged in a matrix and having a diameter of 0.15 mm. Optimizing the material and structure of the first brush 120 improves its durability and pressing effect. In other optional embodiments, the diameter of the bristles can be increased or decreased according to actual needs. During use, the adhesive tape side-wrapping pressing mechanism 10 can rotate the adjusting screw 115 according to actual needs to change the elasticity of the first elastic element 116, thereby adjusting the pressure of the bristles on the adhesive tape 40 and further improving the pressing quality.
[0036] In the embodiments of this utility model, the first elastic element 116 is a linear spring. The linear spring is used to adjust the pressure of the brush bristles on the adhesive paper 40. It has a stable structure and a long service life.
[0037] In the embodiments of this utility model, the length of the interference fit between the first brush 120 and the battery 30 adhesive tape 40 is 12mm-18mm. Through experiments, the optimal interference fit length between the first brush 120 and the battery 30 adhesive tape 40 is 15mm.
[0038] like Figures 4-8 As shown, the connection module includes a second guide rail 221, a second slide block 222, a connection base plate 223, a vertical guide rail 224, a lifting slide block, and a second adjusting screw 115;
[0039] The second guide rail 221 is fixedly mounted on the second bracket 200 near the second through hole 201 along the length / width direction of the second bracket 200. The second slide block 222 is slidably mounted on the second guide rail 221. The connecting base plate 223 has a T-shaped structure. Specifically, the connecting base plate 223 is assembled from an upper plate and a lower plate by multiple screws. The upper plate of the connecting base plate 223 is fixed on the second slide block 222. The vertical guide rail 224 is fixed on the side of the lower plate of the connecting base plate 223 near the second through hole 201. The lower end of the vertical guide rail 224 is provided with a second limiting seat 228. Specifically, the second limiting seat 228 is fixed to the lower end face of the lower plate of the connecting base plate 223. The sliding seat is mounted on the vertical guide rail 224. The upper end face of the lifting slide has a first receiving hole 2253 perpendicular to the second through hole 201. The end of the upper plate of the connecting base plate 223 near the second through hole 201 has a third through hole 2231 coaxial with the first receiving hole 2253. A spring fixing seat 226 is fixed to the end of the upper plate of the connecting base plate 223 near the second through hole 201. The lower end face of the spring fixing seat 226 has a second receiving hole coaxial with the first receiving hole 2253. The upper end of the second elastic element 227 passes through the third through hole 2231 and is inserted into the second receiving hole, while the lower end of the second elastic element 227 is inserted into the first receiving hole 2253. In the adhesive tape wrapping and pressing mechanism 20, when the second brush encounters a protrusion, the second elastic element 227 causes the lifting slide to elastically rise and fall to wrap the adhesive tape, improving the wrapping effect of the adhesive tape.
[0040] Specifically, the lifting slide is pressed against the upper surface of the second limiting seat 228 under the elastic action of the second elastic element 227, that is, the lifting slide is at the lowest position. During the process of wrapping the bottom adhesive paper 40 of the battery 30, if the second brush 230 encounters a protrusion, it is pushed upward by the upward pressure. By setting the second elastic element 227, the first brush 120 can be elastically lifted and lowered to wrap the adhesive paper 40, thereby further improving the wrapping effect of the adhesive paper 40.
[0041] In the embodiments of this utility model, the second elastic element 227 is a linear spring. The linear spring controls the pressure of the brush bristles on the adhesive paper 40. It has a stable structure and a long service life.
[0042] In an embodiment of this utility model, there are two parallel vertical guide rails 224. The lifting slide includes a slider 225 that cooperates with each vertical guide rail 224 and a lifting base 2252 that is fixedly connected to each slider 2251. A first receiving hole 2253 is formed on the upper end face of the lifting base 225. The upper plate of the connecting base plate 223 has an assembly groove 2232 for accommodating a spring fixing seat 226. The spring fixing seat 226 is placed in the assembly groove 2232 and fixed by screws.
