Description

Technical Field

[0001] This utility model relates to the technical field of production equipment for energy storage components, and in particular to a device for attaching adhesive to the end of a roll core. Background Technology

[0002] In the manufacturing process of lithium-ion batteries, tape application is a crucial step after core forming. Its function is to securely fix the positive and negative electrode sheets to the separator by attaching tape to the end of the wound cell, preventing loosening and deformation due to internal stress release during subsequent cutting, assembly, or charging and discharging processes, thus ensuring the integrity and consistency of the cell structure. However, due to current limitations in tape preparation and application methods and layout space, tape application for lithium-ion battery cores cannot accommodate both narrow and wide tapes. For example, some existing tape application equipment achieves tape application of different widths by replacing the entire tape preparation mechanism, resulting in low application efficiency. Utility Model Content

[0012] The adhesive conveying assembly is slidably connected to the second frame, and the adhesive conveying assembly is used to convey the second adhesive tape located at the second adhesive clamping assembly to the pressing surface of the adhesive conveying assembly.

[0013] Furthermore, the adhesive conveying assembly includes an adhesive conveying drive assembly, a first clamp, and a second clamp. Both the first clamp and the second clamp are connected to the second frame via the adhesive conveying drive assembly. The first clamp and the second clamp are located between the second adhesive pressing assembly and the adsorption roller.

[0014] Furthermore, the second adhesive bonding assembly includes an adhesive bonding surface, which is provided with a first air hole for adsorbing the first adhesive tape.

[0015] Furthermore, the second adhesive bonding assembly has a plurality of recesses and protrusions on its adhesive bonding surface, the recesses and protrusions being spaced apart, and the first air hole being disposed on the protrusion.

Furthermore, the placement of the first and second adhesive preparation mechanisms provides a channel for the application mechanism to move the adsorption roller to apply adhesive to the roll core, avoiding interference with the adsorption roller's application process. Simultaneously, the first and second adhesive application mechanisms, located on opposite sides of the application mechanism, do not interfere with each other. Attached Figure Description

[0037] This utility model embodiment discloses a device for attaching adhesive to the end of a roll core.

[0038] Please see Figure 1 One embodiment of the roll core adhesive applicator provided in this utility model includes:

[0039] A device for applying adhesive to the end of a roll core includes an adhesive application mechanism 1, a first adhesive preparation mechanism 2, and a second adhesive preparation mechanism 3.

[0040] The adhesive application mechanism 1 includes an adhesive application drive assembly 12 and an adsorption roller 11 disposed at one end of the adhesive application drive assembly 12. The adhesive application drive assembly 12 is used to drive the adsorption roller 11 to rotate around its central axis and drive the adsorption roller 11 to move in a direction away from the adhesive application assembly to apply adhesive to the core 4.

[0041] The first glue preparation mechanism 2 and the second glue preparation mechanism 3 are located on both sides of the glue application direction of the glue application mechanism 1, respectively. The first glue preparation mechanism 2 includes a first glue preparation area 21 disposed near the adsorption roller 11. The first glue preparation area 21 is used to provide the first tape 202 to cover the adsorption surface of the adsorption roller 11.

[0042] The second adhesive preparation mechanism 3 includes a second adhesive preparation area 31 disposed near the adsorption roller 11. The second adhesive preparation area 31 is used to provide the second adhesive tape 302 to cover the adsorption surface of the adsorption roller 11.

[0043] It is understood that in this embodiment, the first glue preparation mechanism 2 and the second glue preparation mechanism 3 are respectively arranged on both sides of the glue application mechanism 1 in the glue application direction. The first glue preparation mechanism 2 and the second glue preparation mechanism 3 are distributed on both sides of the glue application mechanism 1 and do not affect each other. The first glue preparation area 21 of the first glue preparation mechanism 2 provides the first adhesive tape 202 to cover the adsorption surface of the adsorption roller 11, and the second glue preparation area 31 of the second glue preparation mechanism 3 provides the second adhesive tape 302 to cover the adsorption surface of the adsorption roller 11. The operation of the first glue preparation area 21 and the second glue preparation area 31 does not affect each other, so that the core end glue application device can provide two different widths of adhesive tape to the adsorption roller 11 of the glue application mechanism 1 without replacing or adjusting the glue preparation mechanism. This enables the core end glue application device to be compatible with both wide and narrow adhesive tapes at the same time. At the same time, the arrangement of the first glue preparation mechanism 2 and the second glue preparation mechanism 3 leaves a channel for the glue application mechanism 1 to move the adsorption roller 11 to apply adhesive to the core 4, so as to avoid affecting the adsorption roller 11 to apply adhesive. In practice, users can choose any glue preparation mechanism to work according to the glue application width requirements of the lithium battery core, or they can have two glue preparation mechanisms work alternately as needed during the work process. During the alternation process, there is no need to disassemble or replace the glue preparation mechanism or parts, which significantly improves glue application efficiency and production efficiency.

[0044] It should be noted that, in this embodiment, the tape length refers to the length of the tape along the axial direction on the adsorption roller 11, and the tape width direction is perpendicular to the tape length direction. The tape width refers to the dimension of the tape along the circumference of the adsorption roller 11 when the tape is located on the adsorption roller 11.

[0045] In a more specific embodiment, such as Figure 2 and Figure 3As shown, the first glue preparation mechanism 2 includes a first frame 209, a first glue pressing assembly 208, and a first film roll 201 disposed on the first frame 209, and a first glue clamping assembly 207; the area between the first glue clamping assembly 207 and the first glue pressing assembly 208 is the first glue preparation area 21 and both are located outside the adsorption surface of the adsorption roller 11. The first glue clamping assembly 207 is used to clamp the end of the first adhesive tape 202 output from the first film roll 201. The first glue pressing assembly 208 is coaxially disposed with the adsorption roller 11 and can rotate relative to or synchronously with the adsorption roller 11. The first glue pressing assembly 208 is used to press the first adhesive tape 202 located at the glue outlet end of the first glue clamping assembly 207 onto the adsorption surface of the adsorption roller 11.

[0046] Understandably, in practice, the first pressing assembly 208 presses the first adhesive tape 202 from the adhesive outlet of the first clamping assembly 207 onto the adsorption surface of the adsorption roller 11. The first pressing assembly 208 and the adsorption roller 11 rotate clockwise synchronously, causing the first adhesive tape 202 of a preset width to be pulled out from the first clamping assembly 207 and adsorbed onto the surface of the adsorption roller 11, thus completing the adhesive preparation process of the adsorption roller 11. The first pressing assembly 208 accurately presses the adhesive tape from the adhesive outlet of the first clamping assembly 207 onto the adsorption surface of the adsorption roller 11, and during synchronous rotation, it ensures that the first adhesive tape 202 remains in the predetermined position without deviation, thereby improving the accuracy of adhesive preparation. For wide tapes, during the pulling and adsorption process, the synchronous rotation of the first pressing component 208 and the adsorption roller 11 in this embodiment can maintain the tension of the wide tape, ensuring that the tape is neatly and tightly covered on the adsorption roller 11, and is less likely to sag, cause air pockets and wrinkles or excessive stretching. Therefore, the first glue preparation mechanism 2 in this embodiment is more suitable for preparing glue for wide tapes.

[0047] In a more specific embodiment, the first adhesive preparation mechanism 2 further includes multiple first auxiliary rollers 203. The multiple first auxiliary rollers 203 are disposed between the first film roll 201 and the first adhesive clamping assembly 207. The multiple first auxiliary rollers 203 cooperate with each other to realize the continuous and stable delivery of the first adhesive tape 202 to the first adhesive clamping assembly 207, ensuring that the first adhesive clamping assembly 207 has a continuous supply of adhesive tape, improving production efficiency, and reducing production stagnation and quality fluctuations caused by interruption or instability of adhesive tape supply.

[0048] In a more specific embodiment, the first adhesive preparation mechanism 2 further includes a detection sensor 204, which is disposed between the first auxiliary rollers 203. The first adhesive tape 202 passes through the detection sensor 204. It is understood that the detection sensor 204 is used to detect the output width of the first adhesive tape 202. When the output width of the first adhesive tape 202 reaches a preset length, the detection sensor 204 sends a signal to control the suction roller 11 and the first pressing assembly 208 to stop rotating, triggering the first pressing assembly 208 to press down the first adhesive tape 202, and the first cutting assembly 206 to cut the first adhesive tape 202. In some more specific embodiments, the first adhesive tape 202 is provided with hole markings. When the detection sensor 204 identifies the hole markings, it sends a signal to control the suction roller 11 and the first pressing assembly 208 to stop rotating.

[0049] In a more specific embodiment, the first adhesive preparation mechanism 2 further includes a first cutter drive assembly 205 connected to the first cutter assembly 206. The first cutter assembly 206 is located at the adhesive outlet of the first adhesive clamping assembly 207. By cutting at the adhesive outlet of the first adhesive clamping assembly 207, the tape is subjected to relatively small stretching and tension, and the cutter is subjected to fewer interference factors, which can achieve a smoother and neater cut, avoid problems such as burrs and tears, and improve the appearance quality and performance of the tape.

[0050] In a more specific embodiment, the first glue preparation mechanism 2 further includes a first glue clamping drive assembly 210 connected to the first glue clamping assembly 207. The first glue clamping assembly 207 includes a first clamping plate and a second clamping plate. The first clamping plate is a movable clamping plate, and the second clamping plate is a stationary clamping plate. The stationary clamping plate is fixedly connected to the first frame 209 of the first glue preparation mechanism 2. The movable clamping plate is connected to the first glue clamping drive assembly 210. The first glue clamping drive assembly 210 is used to control the movable clamping plate to move away from or closer to the stationary clamping plate. The movable clamping plate and the stationary clamping plate are greater than or equal to the length of the cut edge of the first adhesive tape 202. Understandably, in specific implementation, when the first pressing assembly 208 and the adsorption roller 11 rotate synchronously to pull the first tape 202, the first clamping drive assembly 210 controls the moving clamp to move away from the stationary clamp, so that the first tape 202 is stably output between the moving clamp and the stationary clamp; when the detection sensor 204 detects that the width of the output of the first tape 202 reaches the preset width, the first clamping drive assembly 210 controls the moving clamp to move closer to the stationary clamp, compacting the first tape 202, so as to assist the first cutting assembly 206 in stable and fast tape cutting.

[0051] In a more specific embodiment, the first pressing assembly 208 includes a pressing frame 212 and a pressing plate 211. The pressing plate 211 is connected to the pressing frame 212 via a first pressing drive assembly 213. It is understood that the first pressing drive assembly 213 is used to control the pressing plate 211 to move away from or closer to the adsorption roller 11.

[0052] In a more specific embodiment, the pressure frame 212 and the pressure plate 211 form a U-shaped structure and are arranged on the outside of the adsorption roller 11. One end of the pressure frame 212 abuts against the pressure plate 211, and the other end is connected to the first synchronous wheel 214. The central axis of the adsorption roller 11 is connected to the second synchronous wheel 215. The first synchronous wheel 214 and the second synchronous wheel 215 are coaxially arranged and respectively connected to the first power source and the second power source on the frame. When the pressure plate 211 presses the adhesive, the first synchronous wheel 214 and the second synchronous wheel 215 rotate simultaneously in the same direction, driving the adsorption roller 11, the pressure frame 212, and the pressure plate 211 to rotate synchronously. When the first tape 202 is completely adsorbed on the adsorption roller 11, the first synchronous wheel 214 and the second synchronous wheel 215 stop rotating simultaneously, driving the adsorption roller 11, the pressure frame 212, and the pressure plate 211 to stop synchronously. When the first adsorption roller 11 performs the adhesive application process on the core 4, the first synchronous wheel 214 is controlled to rotate counterclockwise by the first power source, which drives the adhesive pressing frame 212 and the adhesive pressing plate 211 to rotate counterclockwise and move towards the first cutter assembly 206, so as to avoid affecting the adhesive application operation of the adsorption roller 11.

[0053] In a more specific embodiment, the first cutter drive assembly 205, the first glue clamping drive assembly 210, and the first glue pressing drive assembly 213 all adopt a telescopic cylinder structure. It is understood that the telescopic cylinder has a relatively fast operating speed and can generally complete the extension and retraction actions in a short time, which helps to improve glue preparation efficiency.

[0054] In a more specific embodiment, such as Figures 4-7 The second adhesive preparation mechanism 3 shown includes a second frame 310, a second film roll 301 disposed on the second frame 310, a second adhesive clamping assembly 304, an adhesive conveying assembly 311, and a second adhesive pressing assembly 308. The second adhesive clamping assembly 304 is used to clamp the end of the second adhesive tape 302 output from the second film roll 301. The second adhesive pressing assembly 308 is disposed near the adsorption surface of the adsorption roller 11, and the surface of the second adhesive pressing assembly 308 facing the adsorption roller 11 is the second adhesive preparation area 31. The second adhesive pressing assembly 308 is used to press the second adhesive tape 302 onto the adsorption surface of the adsorption roller 11. The adhesive conveying assembly 311 is slidably connected to the second frame 310 and is used to transport the second adhesive tape 302 located at the second adhesive clamping assembly 304 to the surface of the second adhesive pressing assembly 308.

[0055] Understandably, in specific implementation, the second tape 302 at the second adhesive clamping assembly 304 is conveyed to the second adhesive preparation area 31 by setting the adhesive conveying assembly 311 on the second frame 310, that is, conveyed to the surface of the second adhesive pressing assembly 308 near the adsorption roller 11. In this embodiment, the adhesive conveying assembly 311 and the second adhesive pressing assembly 308 are set on the second frame 310 and are independent of the adsorption roller 11. The positions of the adhesive conveying assembly 311 and the second adhesive pressing assembly 308 are relatively independent and can be flexibly adjusted according to the position of the second adhesive preparation area 31 to avoid conflict with the first adhesive pressing assembly 208 of the first adhesive preparation mechanism 2.

[0056] In a more specific embodiment, the adhesive conveying assembly 311 includes an adhesive conveying drive assembly 312, a first clamp 313 and a second clamp 314. The first clamp 313 and the second clamp 314 are both connected to the second frame 310 through the adhesive conveying drive assembly 312. The first clamp 313 and the second clamp 314 are located between the second pressing assembly 308 and the adsorption roller 11.

[0057] Understandably, in specific implementation, the first clamp 313 and the second clamp 314 clamp both ends of the second tape 302. The first clamp 313 and the second clamp 314 can stably clamp and transport the second tape 302. Furthermore, the contact area between the first clamp 313 and the second clamp 314 and the second tape 302 is small, allowing the second tape 302 to detach from the glue conveying assembly 311 more quickly and transfer to the second glue pressing assembly 308. When the glue conveying assembly 311 is located at the second glue clamping assembly 304, the first clamp 313 clamps the first tape 202 at the glue outlet of the second glue clamping assembly 304, and the second glue clamping assembly 304 clamps the second tape 302 between the second glue clamping assembly 304 and the second auxiliary roller 303. Therefore, in this embodiment, the glue conveying assembly 311 transports a predetermined length of second tape 302 by simultaneously clamping it with the first clamp 313 and the second clamp 314.

[0058] In a more specific embodiment, the adhesive conveying drive assembly 312 adopts a lead screw structure, which can accurately convert rotary motion into linear motion, so that the adhesive conveying assembly 311 can accurately reach the designated position when the second tape 302 is in use.

[0059] In a more specific embodiment, the second film roll 301, the second auxiliary roller 303, the second glue clamping assembly 304, the second cutter assembly 306, and the second glue pressing assembly 308 are all disposed on one side of the frame, and the glue conveying drive assembly 312 is disposed on the other side of the second frame 310. A notch is provided in the middle of the second frame 310 for the passage of the first clamp 313 and the second clamp 314.

[0060] In a more specific embodiment, the second adhesive preparation mechanism 3 further includes multiple second auxiliary rollers 303, which are disposed between the second film roll 301 and the second adhesive clamping assembly 304. The multiple auxiliary rollers cooperate with each other to achieve continuous and stable delivery of the second adhesive tape 302 to the second adhesive clamping assembly 304, ensuring a continuous supply of adhesive tape to the second adhesive clamping assembly 304, improving production efficiency, and reducing production stagnation and quality fluctuations caused by interruption or instability in the supply of the second adhesive tape 302.

[0061] In a more specific embodiment, the second adhesive preparation machine further includes a second cutter assembly 306 and a second cutter drive assembly 307 connected to the second cutter assembly 306. The second cutter assembly 306 is disposed at the adhesive outlet of the second adhesive clamping assembly 304. It is understood that, in specific implementation, by cutting at the adhesive outlet of the second adhesive clamping assembly 304, the second tape 302 is subjected to relatively small stretching and tension, and the cutter is subjected to fewer interference factors, which can achieve a smoother and neater cut, avoid problems such as burrs and tears, and improve the appearance quality and performance of the tape.

[0062] In a more specific embodiment, the second adhesive preparation mechanism 3 further includes a second adhesive clamping drive assembly 305 connected to the second adhesive clamping assembly 304. The first adhesive clamping assembly 207 includes a first clamping plate and a second clamping plate, both of which are movable clamping plates. The two movable clamping plates are distributed on both sides of the second adhesive tape 302. The two movable clamping plates are respectively connected to the two second adhesive preparation mechanisms 305 second adhesive clamping drive assemblies 305. The second adhesive clamping drive assembly 305 is used to control the two movable clamping plates to move away from or closer to each other. The movable clamping plate and the stationary clamping plate are greater than or equal to the length of the cut edge of the second adhesive tape 302. Understandably, in specific implementation, when the adhesive conveying component 311 clamps the second adhesive tape 302 and moves, the distance between the moving clamps needs to be large enough through the second clamp 314. The two second adhesive clamping drive components 305 control the two moving clamps to move away from each other, so that the second clamp 314 and the second adhesive tape 302 can be stably output from between the two moving clamps. When the second clamp 314 moves to the adhesive outlet of the second adhesive pressing component 308, the two second adhesive clamping drive components 305 control the two moving clamps to move closer and press the second adhesive tape 302, so as to assist the second cutting component 306 in cutting the adhesive stably and quickly.

[0063] It should be noted that a length of the second adhesive tape 302 is reserved between the second clamp 314 and the second pressure adhesive assembly 308 to facilitate the second cutter assembly 306 cutting the second adhesive tape 302. Therefore, the total length of the second adhesive tape 302 adsorbed onto the adsorption roller 11 is the sum of the reserved length and the clamping distance between the first clamp 313 and the second clamp 314.

[0064] In a more specific embodiment, the second adhesive bonding assembly 308 includes an adhesive bonding surface 317, which is provided with pores. It is understood that, in specific implementations, the second adhesive tape 302 is adsorbed by the first pores 318 on the adhesive bonding surface 317 of the second adhesive bonding assembly 308, so that it remains stable on the adhesive bonding surface 317 during or after the process of detaching from the first clamp 313 and the second clamp 314.

[0065] In a more specific embodiment, the pressure-pressing surface 317 of the second pressure-pressing assembly 308 is provided with a plurality of recesses 315 and protrusions 316, the recesses 315 and protrusions 316 being spaced apart, and a first air hole 318 being provided on the protrusion 316. It is understood that, in specific implementations, reducing the contact area between the second pressure-pressing assembly 308 and the second adhesive tape 302 allows the second adhesive tape 302 to detach from the second pressure-pressing assembly 308 more quickly and be adsorbed onto the adsorption roller 11.

[0066] In a more specific embodiment, the width of the second adhesive tape 302 is greater than the width of the pressing surface 317. It is understood that, in practice, reducing the contact area between the second pressing assembly 308 and the second adhesive tape 302 allows the second adhesive tape 302 to detach from the second pressing assembly 308 more quickly and be adsorbed onto the adsorption roller 11. This means that after the second pressing assembly 308 has pressed the second adhesive tape 302 onto the adsorption roller 11, the adhesion area between the second adhesive tape 302 and the second pressing assembly 308 is limited. Based on the principle that adhesion force is related to contact area, a smaller contact area reduces the adhesion force on the adhesive tape, allowing it to detach from the second pressing assembly 308 more quickly and be smoothly adsorbed onto the adsorption roller 11. On the other hand, the width of the second tape 302 is greater than the width of the pressing surface 317. When the first clamp 313 and the second clamp 314 clamp the second tape 302, the second tape 302 can be simultaneously adsorbed onto the pressing surface 317, allowing the second tape 302 to transition better from the first clamp 313 and the second clamp 314 to the pressing surface 317, thus preventing the second tape 302 from bending.

[0067] In a more specific embodiment, the second pressure bonding assembly 308 further includes an auxiliary pressure surface 319, on which a second air hole 320 is provided, and the auxiliary pressure surface 319 is lower than the pressure bonding surface 317. It is understood that, in specific implementations, the second air hole 320 on the auxiliary pressure surface 319 can output airflow. When the tape is located between the auxiliary pressure surface 319 and the adsorption roller 11, the airflow output from the second air hole 320 will generate an additional pressure on the portion of the second tape 302 that is not in contact with the pressure bonding surface 317. This pressure can push the second tape 302 closer to the surface of the adsorption roller 11, helping the second tape 302 better adapt to the curved shape of the adsorption roller 11, making the adhesion between the second tape 302 and the second adsorption roller 11 tighter and preventing air pockets.

[0068] In a more specific embodiment, the second pressure bonding assembly 308 is connected to the second frame 310 via the second pressure bonding drive assembly 309. It can be understood that, in specific implementation, the pressure bonding surface 317 of the second pressure bonding assembly 308 is driven to approach or move away from the adsorption roller 11 by the second pressure bonding drive assembly 309.

[0069] In a more specific embodiment, the second cutter drive assembly 307, the second glue clamping drive assembly 305, and the second glue pressing drive assembly 309 all adopt a telescopic cylinder structure. It is understood that the telescopic cylinder has a relatively fast operating speed and can generally complete the extension and retraction actions in a short time, which helps to improve glue preparation efficiency.

[0070] It should be noted that in this embodiment, the second tape 302 is pressed onto the adsorption roller 11 by the pressing surface 317 of the second pressing drive component 309. The width of the pressing surface 317 is limited. In this embodiment, the second adhesive preparation mechanism 3 is preferably used to prepare narrow tape.

[0071] in addition, Figures 1-7 This example only shows that the first glue preparation mechanism 2 is located above the glue application mechanism 1, and the second glue preparation mechanism 3 is located below the glue application mechanism 1. In actual implementation, the second glue preparation mechanism 3 can be located above the glue application mechanism 1 and the first glue preparation mechanism 2 can be located below the glue application mechanism 1, depending on the on-site equipment layout requirements.

[0072] In a more specific embodiment, the adsorption roller 11 is provided with a plurality of adsorption holes evenly distributed on it. This ensures that the adsorption force on each part of the tape is relatively balanced when it is adsorbed, avoiding local adsorption that is too tight or too loose, ensuring that the tape is flatly adhered to the roller surface, and preventing problems such as wrinkles and twisting of the tape during the application process, thereby improving the quality of tape application.

[0073] In a more specific embodiment, the contact surfaces of the first adhesive clamping assembly 207, the second adhesive clamping assembly 304, the adhesive conveying assembly 311, the first adhesive pressing assembly 208, and the second adhesive pressing assembly 308 with the first adhesive tape 202 or the second adhesive tape 302 are all coated with an anti-stick coating. It is understood that by providing the anti-stick coating, the first adhesive tape 202 or the second adhesive tape 302 can be prevented from adhering to the adhesive preparation mechanism, thus affecting the adhesive preparation efficiency. In a more specific embodiment, the anti-stick coating is a polytetrafluoroethylene coating, a perfluoroethylene propylene coating, or a silicone rubber coating, etc.

[0074] The working principle of the adhesive applicator is as follows: After the adsorption roller 11 adsorbs the first adhesive tape 202 or the second adhesive tape 302 from the first adhesive preparation area 21 or the second adhesive preparation area 31, the adhesive applicator drive assembly 12 drives the adsorption roller 11 to move closer to the core 4. When the first adhesive tape 202 or the second adhesive tape 302 is stuck on the core 4, the adsorption roller 11 stops adsorbing the first adhesive tape 202 or the second adhesive tape 302, and the adhesive applicator is completed.

[0075] The working principle of the first glue preparation mechanism 2 is as follows: Before the mechanism operates, the end of the first tape 202 of the first film roll 201 is clamped around the first auxiliary roller 203 and then clamped in the first glue clamping assembly 207. During glue preparation, the first glue clamping drive assembly 210 drives the moving clamping plate away from the stationary clamping plate, and the first glue pressing assembly 208 presses the end of the first tape 202 at the glue outlet of the first glue clamping assembly 207 onto the adsorption surface of the adsorption roller 11. The first power source and the second power source control the first synchronous wheel 214 and the second synchronous wheel 215 to rotate clockwise synchronously, thereby driving the first glue pressing assembly 208 and the adsorption roller 11 to rotate synchronously around the central axis of the adsorption roller 11. When the detection sensor... After the device 204 detects that the first tape 202 has output a preset width, the first power source and the second power source control the first synchronous wheel 214 and the second synchronous wheel 215 to stop rotating. The first adhesive clamping drive assembly 210 drives the moving clamping plate to approach the stationary clamping plate and squeeze the first tape 202. The first cutter assembly 206 cuts the first tape 202 at the glue outlet of the first adhesive clamping assembly 207. The first tape 202 of the preset width is completely adsorbed on the adsorption roller 11. The first power source drives the first synchronous wheel 214 to rotate counterclockwise, driving the first glue pressing assembly 208 to rotate counterclockwise to approach the first cutter assembly 206. The first glue preparation mechanism 2 completes the glue preparation work.

[0076] The working principle of the second glue preparation mechanism 3 is as follows: Before the mechanism operates, the end of the second tape 302 of the second film roll 301 is first clamped around the second auxiliary roller 303 and then clamped in the second glue clamping assembly 304. During glue preparation, the second glue clamping drive assembly 305 drives the two moving clamps to move away from each other. The first clamp 313 of the glue conveying assembly 311 clamps the second tape 302 at the glue outlet of the second glue clamping assembly 304, and the second clamp 314 clamps the second tape 302 located between the second glue clamping assembly 304 and the second auxiliary roller 303. The glue conveying assembly 311 transports the second tape 302. When the second clamp 314 is located at the glue outlet of the second glue clamping assembly 304, the second tape 302 is cut. The cutting assembly cuts the second tape 302 between the second clamp 314 and the second adhesive clamping assembly 304. The adhesive conveying assembly 311 conveys the second tape 302 to the adhesive pressing surface 317 of the second adhesive pressing assembly 308. The adhesive pressing surface 317 adsorbs the second tape 302. The second adhesive pressing drive assembly 309 drives the second adhesive pressing assembly 308 to bring the adhesive pressing surface 317 close to the adsorption roller 11. The adhesive pressing surface 317 presses the second tape 302 onto the surface of the adsorption roller 11. After the adsorption roller 11 completely adsorbs the second tape 302, the second adhesive pressing drive assembly 309 controls the adhesive pressing surface 317 of the second adhesive pressing assembly 308 to move away from the adsorption roller 11. The second adhesive preparation mechanism 3 completes the adhesive preparation work.
