Description

Technical Field

[0001] This utility model relates to the field of multilayer graphite thermal resistance bonding technology, and in particular to a multi-station bonding machine for the production of multilayer graphite thermal resistance bonding. Background Technology

[0002] With the development of electronic technology, the internal space of electronic products is getting smaller and smaller, and the connection density of electronic components is getting larger and larger. As a result, heat is not easily dissipated, leading to more and more heat accumulation inside electronic products. To solve the heat dissipation problem of electronic products, it is often necessary to attach a graphite composite film with high heat dissipation to the cover plate of electronic components with high heat generation. The graphite composite film relies on the high thermal conductivity of graphite film and adopts a multi-layer structure design to greatly increase the heat flux in the direction of heat transfer, and has high heat dissipation efficiency.

[0003] In existing technologies, electronic components are correctly clamped and fixed on a special fixture, a graphite composite film with high heat dissipation is manually applied, and the base film is peeled off. Although some simple single-machine bonding equipment can improve production efficiency to a certain extent, its functions are relatively limited and it can usually only complete a single bonding task.

[0004] Graphite thermally resistive adhesives typically have high precision requirements. Ordinary equipment struggles to achieve precise positioning and bonding, which can easily lead to issues such as loose bonding and gaps between the thermally resistive adhesive and electronic components, affecting heat dissipation. For multilayer graphite thermally resistive adhesives, which require multiple bonding processes, frequent equipment changes or manual transfer are necessary, resulting in a complex production process and a long production cycle. Utility Model Content

[0005] The purpose of this invention is to provide a multi-station laminating machine for the production of multilayer graphite thermal resistance adhesives, which solves the problems of poor bonding and complex production process in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-station laminating machine for producing multi-layer graphite thermally non-resistant adhesives, comprising a frame, a mounting frame slidably connected through the top of the frame, a uniformly distributed sliding plate slidably connected through the top of the mounting frame, a transmission rod rotatably connected through the inner walls of the frame, a transmission device fixedly connected to one end of the outer ring of the transmission rod, a roller fixedly connected to the middle of the outer ring of the transmission rod, a heating component or an adhesive application component provided on the top of the sliding plate, threaded rods threadedly connected through both sides of the top of the mounting frame, a pressure plate rotatably connected to the bottom of the threaded rods, sliding blocks slidably connected to the inner walls of the mounting frame, pressure rollers rotatably connected between the sliding blocks, first pins slidably connected through both ends of the frame, and the first pins slidably connected to the mounting frame, a partition plate slidably connected to one end of each of the two first pins, and the partition plate slidably connected to the frame.

[0007] By adopting the above technical solution, different operations (heating, gluing, etc.) at multiple workstations can be realized. The slide plate can slide on the mounting frame, and the mounting frame can slide on the machine frame, which facilitates the processing of graphite heat-resistant bonding at different positions. The setting of transmission rod, transmission device and roller can realize the transmission of materials. The pressure roller can compact the bonded material. The setting of the first pin and partition facilitates the separation and management of different areas of the equipment, which improves the overall bonding efficiency and quality.

[0008] As a further description of the above technical solution: the heating component includes a slide rod, which is slidably connected to the top of the slide plate, a limit ring is provided on the outer ring of the slide rod, and a heater is fixedly connected to the bottom of the slide rod.

[0009] By adopting the above technical solution, the slide bar can slide on the slide plate, and the height position of the heater can be adjusted according to actual needs. The limiting ring can prevent the slide bar from sliding excessively and detaching from the slide plate, thereby ensuring that the heater heats the graphite non-thermal resistance sticker in the appropriate position, so that the thermal resistance sticker reaches the appropriate bonding temperature and improves the bonding effect.

[0010] As a further description of the above technical solution: the adhesive application assembly includes a storage box, the bottom of which is fixedly connected to the top of the slide plate, and connecting pipes are provided through both sides of the storage box. Fixing plates are fixedly connected to both sides of the bottom of the slide plate, and a second pin is slidably connected through one end of each fixing plate.

[0011] By adopting the above technical solution, the storage box is used to store the glue required for gluing, and the connecting pipe can transport the glue in the storage box to the gluing roller. The setting of the fixing plate and the second pin facilitates the installation and disassembly of the material roller and the gluing roller, making it convenient to maintain and replace the gluing components. At the same time, the positions of the material roller and the gluing roller can be adjusted according to the actual gluing needs.

[0012] As a further description of the above technical solution: a material roller is provided at one end of the second pin at the top, and a glue-applying roller is provided at one end of the second pin at the bottom, and the glue-applying roller passes through and is rotatably connected to the connecting pipe.

[0013] By adopting the above technical solution, the material roller can guide and convey the material before gluing. The gluing roller is rotatably connected to the connecting pipe, and can obtain glue from the connecting pipe during rotation and evenly coat the graphite heat-resistant adhesive, thereby realizing the gluing function, ensuring the uniformity and stability of the gluing, and thus improving the bonding quality.

[0014] As a further description of the above technical solution: a nut is threaded to the bottom of the outer ring of the threaded rod.

[0015] By adopting the above technical solution, the nut can cooperate with the threaded rod. After adjusting the height of the pressure plate, tightening the nut can fix the threaded rod and prevent the pressure plate from moving due to vibration or other reasons during operation, thereby ensuring that the pressure plate applies stable pressure to the material and ensuring the bonding effect.

[0016] As a further description of the above technical solution: a fixed rod is slidably connected through the top of the sliding block, and the fixed rod is fixedly connected to the inner wall of the mounting frame.

[0017] By adopting the above technical solution, the fixed rod provides a guide for the sliding block, enabling the sliding block to slide smoothly up and down within the mounting frame, ensuring that the pressure roller can accurately compact the material during operation, and improving the precision and stability of the pressing.

[0018] As a further description of the above technical solution: the outer ring of the fixing rod is fitted with a spring, and the spring is located between the pressure plate and the sliding block.

[0019] By adopting the above technical solution, the spring plays the role of buffering and elastic support. When the pressure plate moves downward to apply pressure to the material, the spring can compress and rebound to a certain extent according to factors such as the thickness of the material, so that the pressure is applied to the material more evenly. At the same time, it can also avoid damage to the material due to excessive pressure, and improve the adaptability of the equipment to materials of different thicknesses.

[0020] As a further description of the above technical solution: a brake motor is fixedly connected to one side of one end of the frame, and the output end of the brake motor is fixedly connected to a transmission rod at one end.

[0021] By adopting the above technical solution, the brake motor can provide power to the transmission rod, drive the transmission rod to rotate, and then drive the roller to rotate, realizing the conveying of materials such as graphite thermally non-resistive adhesive. The brake motor can brake quickly when needed, precisely control the material conveying position and speed, ensure the accuracy and stability of the production process, and also facilitate the start-up, shutdown and adjustment of the equipment.

Simultaneously, the number of mounting frames is adjustable, and with the through-sliding connection design, first pin, and partition, the equipment can quickly complete assembly, disassembly, and positioning, meeting different needs from small- to large-scale production. This greatly improves the equipment's versatility and scalability, reducing the cost for enterprises to replace equipment due to process changes or capacity adjustments.

[0024] 2. The present invention provides a multi-station laminating machine for producing multi-layer graphite thermal resistance adhesive. The partition can separate the workstations to prevent interference and use the smooth side to limit the graphite material, ensuring that the material is transported smoothly along the preset path, providing a stable foundation for precise lamination. The modular design of each component of the equipment makes the mounting frame, slide plate, glue application component and heating component easy to disassemble and assemble, facilitating daily maintenance, cleaning and troubleshooting.

[0035] Combination Figure 1 and Figure 2This utility model discloses a multi-station laminating machine for producing multi-layer graphite heat-resistant adhesive tape. It includes a frame 1, with a transmission rod 3 rotatably connected through the inner walls of the frame 1.

A brake motor 2 is fixedly connected to one side of one end of the frame 1, and the output end of the brake motor 2 is fixedly connected to one end of the transmission rod 3. During the conveying process, a partition 6 plays a crucial role. Through sliding cooperation with the frame 1 and the first pin 4, its position can be adjusted as needed. This not only effectively separates different workstations and prevents mutual interference between multi-layer graphite heat-resistant adhesive tapes during production, but also acts as a guide device, using its smooth sides to limit the graphite material, preventing material deviation and ensuring that the graphite heat-resistant adhesive tape is smoothly conveyed along a preset path, laying the foundation for subsequent precise lamination.

The surface of the rollers 7 is specially treated and has a good coefficient of friction and flatness. During the rotation, it can convey graphite non-thermal resistance adhesive material with constant tension and stable speed, ensuring production continuity and material conveying accuracy.

[0038] Working principle: During use, the number of slide plates 10 and adhesive application components can be adjusted according to customer needs, as can the number of mounting frames 5. When the brake motor 2 is turned on, its output rotates, driving the transmission rod 3 to rotate. Through the transmission device 9, the remaining transmission rods 3 rotate, thereby driving the roller 7 to rotate. The number of multi-layer graphite heat-resistant adhesive sheets produced can be adjusted through the partition plate 6, while preventing graphite misalignment. The pressure of the pressure roller 8 can be adjusted through the mounting frame 5, sliding block 14, fixing rod 15, spring 16, pressure plate 17, threaded rod 18, and nut 19.
