Description

Technical Field

[0001] This utility model relates to the technical field of heat sink fin processing equipment, specifically a heat sink fin processing and cutting device. Background Technology

[0002] Heat sink fins are heat dissipation components that accelerate heat transfer by increasing surface area. They are usually made of materials with good thermal conductivity, such as copper and aluminum, and are commonly found in devices such as computer CPUs and car radiators. Their core function is to quickly conduct the heat generated by the heat source and dissipate it into the air to maintain the normal operating temperature of the device.

[0003] The processing of heat sink fins includes extrusion for mass production, brazing for complex high-density structures, and stamping for thin and simple fins. All processes include raw material handling, forming, and subsequent optimization. During processing, the process must be selected based on the material characteristics, and auxiliary processes such as surface treatment and precision testing are used to ensure the heat dissipation efficiency and durability of the final product. In the extrusion process, cutting is used to process continuous long strips into the required size. Special cutting equipment must be used to cut the long strips into individual fin units according to the design height of the heat sink.

[0004] Existing fin cutting devices are mostly fixed structures. After each cut, the fins need to be disassembled and then repositioned for the next cut. This process is cumbersome and affects the cutting speed of the fins.

[0005] Therefore, a heat sink fin processing and cutting device is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

By adding the rack and gear for cooperation, after the heat sink fins are cut, they can be recut in the next area without disassembly and reinstallation. At the same time, the addition of the vacuum suction cup can fix the heat sink fins, reducing vibration during cutting and preventing misalignment of the heat sink fins.

By adding a collection box, processing debris can be collected inside the collection box, reducing the accumulation of debris inside the collection box and the inconvenience of subsequent cleaning. At the same time, adding a scraper can compress the processing debris, and the compressed debris will occupy a better area.

[0010] Preferably, a connecting frame is fixedly connected to the side wall of the workbench; a spring telescopic rod is fixedly connected to the inner side wall of the connecting frame; and oil-absorbing cotton is fixedly connected to the end of the spring telescopic rod. By adding oil-absorbing cotton, the rack can be lubricated, reducing the occurrence of rust on the surface of the rack after long-term use. The lubricating oil inside the oil-absorbing cotton can keep the rack in good working condition for a long time.

[0011] Preferably, the support frame has a sliding groove inside; a hook is slidably arranged inside the sliding groove; by adding the hook, the operating tools can be collected, reducing the situation where it is inconvenient to store the tools needed when processing the heat sink fins.

[0012] Preferably, a rubber pad is fixed to the outer wall of the workbench; multiple rubber pads are provided; by adding rubber pads, the operator can reduce direct contact with the workbench, and the rubber pads can play a buffering role.

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 scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a heat sink fin processing and cutting device includes a worktable 1, a support frame 11 fixedly connected to the top of the worktable 1; a linear motor 12 is installed inside the support frame 11; a placement seat 13 is slidably installed outside the linear motor 12; a cutting tool 14 is rotatably installed on the inner side wall of the placement seat 13; a first motor 17 is fixedly connected to the bottom of the worktable 1; a gear 18 is fixedly connected to the output end of the first motor 17; a rack 16 is installed inside the worktable 1; a vacuum suction cup 15 is fixedly connected to the top of the rack 16; an air injection port 19 is opened on the side wall of the vacuum suction cup 15; the heat sink fins are first placed on the top of the vacuum suction cup 15, and then the air injection port 19 is connected to a vacuum pump. After the connection is completed, the vacuum pump can be started, and the vacuum pump will generate negative pressure inside the vacuum suction cup 15. Then the heat sink fins will be attracted to the top of the vacuum suction cup 15. Then the linear motor 12 can be started, and the linear motor 12 will drive the placement seat 13 to open. After connecting the cutting tool 14 to the power source, it begins to rotate and cuts the heat sink fins. Once a portion of the heat sink fins has been cut, the first motor 17 is started, which then drives the gear 18 to rotate. As the gear 18 rotates, the rack 16 is also driven to move linearly. When the rack 16 moves linearly, the vacuum suction cup 15 at the top of the rack 16 and the heat sink fins are also driven to move linearly. Once the uncut portion of the heat sink fins has been moved to the bottom of the cutting tool 14, the first motor 17 is turned off. By adding the rack 16 and gear 18, the heat sink fins can be cut again without disassembly and reinstallation after cutting. At the same time, the vacuum suction cup 15 can fix the heat sink fins, reducing vibration during cutting and preventing misalignment of the heat sink fins.

[0026] like Figures 1 to 3 As shown, a second motor 21 is fixedly connected to the side wall of the support frame 11; a fan 2 is fixedly connected to the output end of the second motor 21; a connecting box 22 is fixedly connected to the inner side wall of the support frame 11; a placement plate 23 is fixedly connected to the top of the workbench 1; and multiple cooling fins are fixedly connected to the inner side wall of the placement plate 23. When the heat dissipation fins are cut by the cutting tool 14, the second motor 21 can be started, and then the second motor 21 will drive the fan 2 to rotate. At the same time, the cooling fins on the inner side wall of the placement plate 23 can be activated. At this time, the air blown out by the fan 2 will be turned into cool air after passing through the cooling fins, and the fan 2 will cool down the surface of the heat dissipation fins. By adding the fan 2, the temperature generated when the heat dissipation fins are cut can be cooled down, reducing the excessively high temperature at the cutting position of the heat dissipation fins, which may lead to subsequent deformation or even thermal expansion.

[0027] like Figures 1 to 4As shown, a collection box 31 is fixedly connected to the top of the workbench 1; a filter screen 32 is installed inside the workbench 1; an electric push rod 33 is fixedly connected to the inner wall of the collection box 31; a scraper 3 is fixedly connected to the end of the electric push rod 33; when the fan 2 blows air onto the surface of the heat dissipation fins, the fan 2 blows the cutting debris on the surface of the heat dissipation fins into the collection box 31. Then the filter screen 32 filters the cutting debris. Smaller cutting debris will fall into the workbench 1 through the filter screen 32, while larger debris will remain on the surface of the filter screen 32. At the same time, the electric push rod 33 can be activated, which will drive the scraper 3 to move. The scraper 3 will scrape off the debris from the inner wall of the collection box 31. By adding the collection box 31, the processing debris can be collected inside the collection box 31, reducing the accumulation of debris inside the collection box 31 and the inconvenience of subsequent cleaning. At the same time, adding the scraper 3 can compress the processing debris, and the compressed debris will occupy a better area.

[0028] like Figure 5 As shown, a connecting frame 41 is fixedly connected to the side wall of the workbench 1; a spring telescopic rod 42 is fixedly connected to the inner side wall of the connecting frame 41; an oil-absorbing cotton 4 is fixedly connected to the end of the spring telescopic rod 42; lubricating oil is first injected into the oil-absorbing cotton 4, and then when the rack 16 moves to the outside of the workbench 1, it will come into contact with the oil-absorbing cotton 4, and the oil-absorbing cotton 4 will lubricate the surface of the rack 16. When the rack 16 contacts the oil-absorbing cotton 4, the spring telescopic rod 42 will drive the oil-absorbing cotton 4 to move up and down, and the spring telescopic rod 42 can make the oil-absorbing cotton 4 stick tightly to the surface of the rack 16; by adding the oil-absorbing cotton 4, the rack 16 can be lubricated, reducing the occurrence of rust on the surface of the rack 16 after long-term use, and the lubricating oil inside the oil-absorbing cotton 4 can keep the rack 16 in good working condition for a long time.

[0029] like Figures 1 to 4 As shown, the support frame 11 has a sliding groove 51 inside; a hook 5 is slidably arranged inside the sliding groove 51; when the workbench 1 is processing, if it is necessary to hang something, the thing can be hung inside the hook 5, and then the hook 5 can be slid, and the hook 5 will slide inside the sliding groove 51; by adding the hook 5, the operating tools can be collected, reducing the situation where it is inconvenient to store the tools needed when processing the heat sink fins.

[0030] like Figure 2 As shown, a rubber pad 6 is fixed to the outer wall of the workbench 1; multiple rubber pads 6 are provided; when the operator comes into contact with the workbench 1, they will first come into contact with the rubber pad 6; by adding rubber pads 6, the operator can reduce direct contact with the workbench 1, and the rubber pads 6 can play a buffering role.

[0031] Working principle: First, place the heat dissipation fins on top of the vacuum suction cup 15. Then, connect the air injection port 19 to the vacuum pump. After connection, start the vacuum pump. The vacuum pump will generate negative pressure inside the vacuum suction cup 15, and the heat dissipation fins will be attracted to the top of the vacuum suction cup 15. Next, start the linear motor 12. The linear motor 12 will drive the placement seat 13 to start linear motion. After connecting the cutting tool 14 to the power source, the cutting tool 14 will start rotating. At this time, the cutting tool 14 will cut the heat dissipation fins. When a part of the heat dissipation fins has been cut, start the first electric motor. Motor 17 then drives gear 18 to rotate. As gear 18 rotates, rack 16 is also driven to move linearly. During this linear motion, the vacuum suction cup 15 and heat dissipation fins at the top of rack 16 are also driven to move linearly. Once the uncut portion of the heat dissipation fins is moved to the bottom of the cutting tool 14, motor 17 is turned off. When the heat dissipation fins are cut by the cutting tool 14, motor 21 can be started. Motor 21 then drives fan 2 to rotate, simultaneously activating the cooling fins on the inner wall of the placement plate 23. The air blown by fan 2 is cooled after passing through the cooling fins, thus cooling the surface of the heat sink fins. When fan 2 blows air onto the heat sink fins, it blows the cutting debris onto the surface into the collection box 31. The filter 32 then filters the debris; smaller debris falls through the filter 32 into the workbench 1, while larger debris remains on the filter 32. Simultaneously, the electric actuator 33 is activated, moving the scraper 3 to remove debris from the inner wall of the collection box 31, first into the oil-absorbing cotton 4. Lubricating oil is injected into the part. When the rack 16 moves to the outside of the worktable 1, it will come into contact with the oil-absorbing cotton 4. The oil-absorbing cotton 4 will lubricate the surface of the rack 16. When the rack 16 contacts the oil-absorbing cotton 4, the spring telescopic rod 42 will drive the oil-absorbing cotton 4 to move up and down. The spring telescopic rod 42 can make the oil-absorbing cotton 4 stick tightly to the surface of the rack 16. When the worktable 1 is processing, if it is necessary to hang something, it can be hung inside the hook 5. Then the hook 5 can be slid. The hook 5 will slide inside the slide groove 51. When the operator touches the worktable 1, it will first come into contact with the rubber pad 6.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
