Description

Technical Field

[0001] This utility model relates to the field of silicone pad production, and in particular to a dispensing device for producing high thermal conductivity silicone pads. Background Technology

[0002] High thermal conductivity silicone pads are widely used in the heat dissipation management of electronic devices as a highly efficient thermal interface material. In the production process of high thermal conductivity silicone pads, the dispensing process is a crucial step. This process usually involves precisely coating liquid high thermal conductivity silicone onto the substrate to form an adhesive layer with a specific pattern and thickness, which is then cured and molded.

[0003] To improve production efficiency and meet the production needs of large-area or complex patterned gaskets, modern dispensing equipment generally adopts multi-head dispensing technology, which integrates multiple dispensing heads on a single dispensing module to achieve synchronous, multi-point coating. However, existing multi-head dispensing devices generally have a problem: the relative spacing between the multiple dispensing heads in existing devices is fixed and cannot be flexibly adjusted according to actual production needs. As electronic products become smaller, thinner, and more diverse, the size, shape, and internal layout of thermally conductive holes and clearance holes of high thermal conductivity silicone gaskets vary greatly. When producing gaskets of different specifications or with different dispensing patterns, the spacing of the dispensing heads must be precisely matched with the glue dots or glue line array on the gasket. For dispensing devices with fixed spacing, if the product model is changed and the dispensing head spacing does not match the new product, the entire dispensing module needs to be replaced or returned to the factory for modification. This not only requires a large investment in spare parts but also causes long-term downtime of the production line, seriously affecting the execution of production plans and equipment utilization. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dispensing device for producing high thermal conductivity silicone pads. Through a sliding component, the user can adjust the spacing between the dispensing heads according to actual production needs, enabling the device to handle different production tasks of high thermal conductivity silicone pads, improving the equipment's adaptability to the production of pads of different specifications, and meeting diverse production requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dispensing device for producing high thermal conductivity silicone pads, comprising a dispensing device body, a support frame fixedly connected to the front top of the dispensing device body, a fixed plate fixedly connected to the top of the support frame, an electric push rod fixedly connected to the right end of the fixed plate, the driving end of the electric push rod penetrating the inner wall of the support frame and fixedly connected to a sliding plate, a sliding component provided on the inner wall of the sliding plate, the sliding plate being connected to a fixed frame through the sliding component, a storage box fixedly connected to the front end of the outer wall of the support frame, a plurality of flexible tubes fixedly connected to the bottom end of the storage box, a cap fixedly connected to the outer wall of the flexible tubes, and a glue cylinder clamped at the bottom end of the cap, the glue cylinder being used for dispensing glue.

[0006] Furthermore, the sliding assembly includes a plurality of wheels slidably connected to the inner wall of the slide plate, a fixed post rotatably connected to the inner wall of the wheels, a connecting plate fixedly connected to the front end of the fixed post, a connecting plate rotatably connected to the inner wall of the connecting plate, a protective frame fixedly connected to the inner wall of the connecting plate, and a rubber tube clamped to the inner wall of the protective frame.

[0007] Furthermore, the inner wall of the skateboard is provided with several grooves, and the outer wall of the wheel is slidably connected to the inner wall of the grooves.

[0008] Furthermore, a fixing box is fixedly connected to the top of the connecting plate, a compression spring is fixedly connected to the inner wall of the fixing box, a pressure plate is fixedly connected to the top of the compression spring, and the outer wall of the pressure plate is slidably connected to the inner wall of the fixing box.

[0009] Furthermore, a threaded rod is threadedly connected to the rear end of the inner wall of the fixing box, and a pressure ring is fixedly connected to the front end of the outer wall of the threaded rod. The front end of the pressure ring is engaged with the top end of the outer wall of the rubber tube.

[0010] Furthermore, the outer wall of the hose is slidably connected to the rear end of the inner wall of the connecting plate, the top of the storage box is fixedly connected to the inlet, and the right end of the storage box is fixedly connected to the pressure pump, which is used to pressurize the glue in the storage box and enter the hose.

[0011] This utility model has the following beneficial effects: In this invention, the sliding component allows users to adjust the spacing between the dispensing heads according to actual production needs, enabling the device to handle the production tasks of different high thermal conductivity silicone pads. This effectively shortens product changeover time, reduces spare parts costs caused by module replacement, and improves the equipment's adaptability to the production of pads of different specifications, thus meeting diverse production needs.

[0012] In this invention, by pressing down on the pressure plate, the pressure plate squeezes the spring and disengages from the inner wall of the connecting plate. Then, the pressure plate is pulled back to quickly release the restriction on the rubber tube, allowing the rubber tube to be removed and replaced. This improves positioning accuracy and repeatability, shortens line changeover and equipment debugging time, and maximizes the effective utilization of the equipment. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figure 1 - Figure 3This utility model provides an embodiment of a dispensing device for producing high thermal conductivity silicone pads, comprising a dispensing device body 1. A support frame 2 is fixedly connected to the front top of the dispensing device body 1. A control panel is fixedly connected to the right end of the support frame 2. Several buttons and indicator lights are provided on the outer wall of the control panel. The buttons are used to manually control the movement of the dispensing machine and the dispensing process, and the indicator lights are used to display the working status of the machine. A fixing plate is fixedly connected to the top of the support frame 2. An electric push rod 3 is fixedly connected to the right end of the fixing plate. The driving end of the electric push rod 3 penetrates the inner wall of the support frame 2 and is fixedly connected to a sliding plate 10. A sliding component is provided on the inner wall of the sliding plate 10. The sliding plate 10 is connected to the fixing frame 1 via the sliding component. The sliding assembly includes several wheels 11 slidably connected to the inner wall of the slide plate 10. A fixed column 13 is rotatably connected to the inner wall of the wheel 11. A connecting plate 4 is fixedly connected to the front end of the fixed column 13. A connecting plate 17 is rotatably connected to the inner wall of the connecting plate 4. A protective frame 21 is fixedly connected to the inner wall of the connecting plate 17. A glue cylinder 5 is clamped in the inner wall of the protective frame 21. Several sliding grooves 12 are provided on the inner wall of the slide plate 10. The outer wall of the wheel 11 is slidably connected to the inner wall of the sliding groove 12. A storage box 8 is fixedly connected to the front end of the outer wall of the support frame 2. Several hoses 7 are fixedly connected to the bottom end of the storage box 8. A cover 6 is fixedly connected to the outer wall of the hoses 7. A glue cylinder 5 is clamped in the bottom end of the cover 6. The glue cylinder 5 is used for dispensing glue.

[0017] Specifically, after all the glue cartridges 5 are installed, the operator injects the glue into the storage box 8 through the feed inlet 9. Then, by placing the high thermal conductivity silicone pad to be glued in the designated working area of ​​the dispensing device body 1, and then, according to the actual dispensing process requirements, the electric push rod 3 is activated. The electric push rod 3 pushes the slide plate 10 downward. During the movement of the slide plate 10, the internal groove 12 interacts with the rotating wheel 11, causing the rotating wheel 11 to slide along the trajectory of the groove 12. The rotating wheel 11 is connected to the connecting plate 4 through the fixed column 13, so the sliding of the rotating wheel 11 is converted into the sliding of the connecting plate 4. The horizontal sliding on the fixed frame 14, through this linkage mechanism, allows the spacing between multiple glue tubes 5 to be precisely and synchronously opened until the preset dispensing spacing is reached, realizing stepless adjustment of the dispensing head spacing to adapt to the needs of workpieces of different sizes and dispensing layouts. After the spacing adjustment is completed, the pressure pump 15 is started, and the pressure pump 15 delivers the dispensing liquid in the storage box 8 to each glue tube 5 through the hose 7. The dispensing liquid enters the inside of the glue tube 5 through the cap 6 and is finally evenly discharged from the dispensing head at the bottom of the glue tube 5, completing the precise dispensing operation of the high thermal conductivity silicone pad.

[0018] Reference Figure 3 - Figure 5A fixed box 18 is fixedly connected to the top of the connecting plate 17. A compression spring 22 is fixedly connected to the inner wall of the fixed box 18. A pressure plate 16 is fixedly connected to the top of the compression spring 22. The outer wall of the pressure plate 16 is slidably connected to the inner wall of the fixed box 18. A threaded rod 19 is threadedly connected to the rear end of the inner wall of the fixed box 18. A pressure ring 20 is fixedly connected to the front end of the outer wall of the threaded rod 19. The front end of the pressure ring 20 is locked at the top of the outer wall of the glue cylinder 5. The outer wall of the hose 7 is slidably connected to the rear end of the inner wall of the connecting plate 4. A feed port 9 is fixedly connected to the top of the storage box 8. The feed port 9 is used to fill the glue into the storage box 8. A pressure pump 15 is fixedly connected to the right end of the storage box 8. The pressure pump 15 is used to pressurize the glue in the storage box 8 and enter the hose 7.

[0019] Specifically, the operator manually presses the pressure plate 16 in the device. The pressure plate 16 can slide vertically within the inner wall of the fixing box 18. During the pressing process, the pressure plate 16 moves downward, compressing the internal compression spring 22. As the compression spring 22 elastically deforms, the pressure plate 16 gradually disengages from the slot of the connecting plate 4. At this point, the pressure plate 16 is in a freely movable state, creating operating space for the subsequent installation of the glue cartridge 5. After the pressure plate 16 disengages, the operator can continue to press the pressure plate 16 and rotate it backward. At this time, the pressure plate 16 rotates through the connecting plate 17, thereby unfolding the bottom of the originally closed connecting plate 4, allowing the glue cartridge 5 to be smoothly inserted into the closed space formed by the connecting plate 4, the protective frame 21, etc., ensuring that the installation process is unobstructed. Then, after accurately placing the glue cartridge 5 into the unfolded closed space, the operator rotates the pressure plate 16 in the opposite direction. At this point, the pressure plate 16 is released, and the spring 22 quickly rebounds due to its elastic restoring force, pushing the pressure plate 16 back into the slot of the connecting plate 4, thus locking the pressure plate 16 and ensuring the stable installation of the glue cartridge 5. This also enables a quick, tool-free operation, significantly improving the efficiency of the replacement process. While the pressure plate 16 is reset, the fixing box 18 connected to its outer wall moves the protective frame 21 through the connecting plate 17, effectively limiting the bottom of the glue cartridge 5 and preventing the glue cartridge 5 from shifting or loosening during the dispensing process. At the same time, the operator rotates the threaded rod 19, causing the pressure ring 20 at the front end of the threaded rod 19 to move forward until it is tightly fitted to the top of the glue cartridge 5, thus completing the limiting and fixing of the top of the glue cartridge 5. Finally, the cap 6 is inserted into the top of the glue cartridge 5, completing the sealing and installation of the entire glue cartridge 5. The above steps are then repeated until all the glue cartridges 5 that need to be used are installed and fixed.

[0020] Working principle: First, by pressing one of the pressure plates 16 of the pressing device, the pressure plate 16 slides downward in the inner wall of the fixing box 18, causing the pressure plate 16 to squeeze the spring 22 and disengage from the connecting plate 4. Then, the pressure plate 16 can be pressed and rotated backward, causing it to rotate through the connecting plate 17, opening the closed space of the connecting plate 4. Then, the glue tube 5 is inserted into the closed space. Then, the pressure plate 16 is rotated in the opposite direction to return it to its original position and released, causing the spring 22 to rebound and lock the pressure plate 16 back into the connecting plate 4. While the pressure plate 16 is locked, the fixing box 18 on the outer wall of the pressure plate 16 limits the bottom of the glue tube 5 through the connecting plate 17. At the same time, by rotating the threaded rod 19, the threaded rod 19 pushes the pressure ring 20 forward, limiting the top of the glue tube 5. Then, the top of the cap 6 can be inserted into the top of the glue tube 5 to complete the sealing of the glue tube 5. This is considered as completing the installation of one glue tube 5.

[0021] Then repeat the above operation until all glue cartridges 5 are confined. Then, pass the glue into the storage box 8 through the feed port 9. Then, place the high thermal conductivity silicone pad to be glued on the glue dispensing device body 1. Then, according to the required glue dispensing position, start the electric push rod 3 to push the slide plate 10 downward. Through the sliding of the slide plate 10, the rotating wheel 11 slides in the groove 12 opened in the slide plate 10. The rotating wheel 11 drives the connecting plate 4 connected to the fixed column 13 to slide to both sides on the fixed frame 14 through the fixed column 13, gradually widening the gap between the glue cartridges 5 to the appropriate glue dispensing distance. Then, add the glue to the storage box 8 through the feed port 9. Then, start the pressure pump 15 to add the glue from the storage box 8 into the hose 7, and enter the glue cartridge 5 through the cap 6 on the hose 7. Then, it is discharged from the bottom of the glue cartridge 5, completing the glue dispensing.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
