Description

Technical Field

[0001] This utility model relates to the field of heat dissipation fin processing technology, specifically to a grooving device for heat dissipation fin surface. Background Technology

[0002] Heat sinks, also known as heat dissipation fins, are classified as "passive heat dissipation components" in the field of electronic engineering design. They are made of metals with good thermal conductivity, light weight, and easy processing (mostly aluminum or copper; silver is too expensive and generally not used) and are attached to the heat-generating surface to dissipate heat through a composite heat exchange mode.

[0003] During the production process of heat sink fins, grooves need to be cut into their surface to improve heat dissipation efficiency. However, during the grooving process of existing heat sink fins, debris falls onto the worktable, causing the debris to be pressed between the worktable and the heat sink fin when grooving the next heat sink fin, resulting in unevenness and errors in the grooving process. To address these issues, the inventors have proposed a heat sink fin surface grooving device. Utility Model Content

[0004] To address the problem that during the grooving process of heat sink fins, debris falls onto the worktable, causing unevenness and errors in the grooving of the next heat sink fin, this invention aims to provide a grooving device for heat sink fins.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: a grooving device for heat dissipation fins, including a worktable, a frame fixedly mounted on the top surface of the worktable, a threaded rod rotatably mounted inside the frame, a brush mounted above the worktable, a fixing block fixedly mounted on the top surface of the brush, an L-shaped plate fixedly mounted on one side of the fixing block, a threaded block fixedly mounted on one side of the L-shaped plate, the threaded block being threaded onto the outer surface of the threaded rod, a first motor mounted on one side of the frame, a rotating shaft fixedly mounted on the output end of the first motor, a first bevel gear fixedly mounted on the outer surface of the rotating shaft, and a second bevel gear fixedly mounted on one end of the threaded rod. The first bevel gear meshes with the second bevel gear. First, the heat dissipation fins to be grooved are placed on a placement plate. By activating an electric push rod, the clamping plate is clamped and fixed. By activating a cylinder, the support frame is lowered, allowing the cutting wheel to approach the surface of the heat dissipation fins. Simultaneously, the... The third motor rotates the cutting wheel to groove the surface of the heat sink fins. After grooving, the cylinder retracts and the second motor is activated, causing the lead screw to rotate and the movable block to move the horizontal plate. This allows adjustment of the cutting wheel, enabling the cutting of different positions of the heat sink fins as needed. After grooving, the electric push rod is activated to retract the clamping plate. Simultaneously, the L-shaped plate and fixed block drive the brush to clean debris without touching the mounting plate and clamping plate. The first motor is activated, causing the rotating shaft to rotate the first bevel gear. The first bevel gear meshes with the second bevel gear, causing the threaded rod to rotate. This causes the threaded block to move the L-shaped plate, simultaneously driving the brush to clean the surface of the placement plate and remove debris from the grooving process. This ensures that the next heat sink fin can be placed flat on the placement plate, improving the quality of the heat sink grooving. During cleaning, debris can be collected in a collection box for centralized processing.

In this utility model, the L-shaped plate is moved by the threaded block, and at the same time the brush is driven to clean the surface of the placement plate and remove the debris when the groove is cut, so that when the next heat sink fin is grooved, it can be placed flat on the placement plate, thus improving the quality of heat sink fin grooving.

[0010] 2. In this utility model, after the heat dissipation fins to be slotted are placed on the placement plate, the electric push rod is turned on to clamp and fix the clamping plate, thereby preventing the heat dissipation fins from shifting during the slotting process.

[0019] 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.

[0020] Example: Figure 1-6 As shown, this utility model provides a grooving device for heat dissipation fins, including a workbench 1, a frame 2 fixedly mounted on the top surface of the workbench 1, a threaded rod 24 rotatably mounted inside the frame 2, a brush 29 mounted above the workbench 1, a fixing block 28 fixedly mounted on the top surface of the brush 29, an L-shaped plate 27 fixedly mounted on one side of the fixing block 28, a threaded block 26 fixedly mounted on one side of the L-shaped plate 27, the threaded block 26 being threadedly sleeved on the outer surface of the threaded rod 24, a first motor 21 mounted on one side of the frame 2, a rotating shaft 22 fixedly mounted on the output end of the first motor 21, and a first... A second bevel gear 25 is fixedly provided at one end of the bevel gear 23 and the threaded rod 24. The first bevel gear 23 meshes with the second bevel gear 25. By turning on the first motor 21, the rotating shaft 22 drives the first bevel gear 23 to rotate. The first bevel gear 23 meshes with the second bevel gear 25, which in turn causes the threaded rod 24 to rotate. This causes the threaded block 26 to move the L-shaped plate 27, and at the same time, it drives the brush 29 to clean the surface of the placement plate 14 and remove the debris from the slotting process. This ensures that when the next heat sink fin is slotted, it can be placed flat on the placement plate 14, thus improving the quality of the heat sink fin slotting.

[0021] A fixed frame 12 is fixedly provided on the top surface of the workbench 1. A connecting block 13 is fixedly provided inside the fixed frame 12. A placement plate 14 is fixedly provided inside the connecting block 13. A support plate 15 is fixedly provided on both sides of the placement plate 14. An mounting plate 16 is fixedly provided on the top surface of the support plate 15. An electric push rod 17 is installed on one side of the mounting plate 16. A clamping plate 18 is fixedly provided at the output end of the electric push rod 17. A through groove 101 is provided inside the workbench 1. A collection box 11 is fixedly provided on the bottom surface of the workbench 1. The through groove 101 and the collection box 11 are interconnected.

[0022] By adopting the above technical solution, after placing the heat dissipation fins to be slotted on the placement plate 14, the electric push rod 17 is activated to clamp and fix the clamping plate 18, thereby preventing the heat dissipation fins from shifting during the slotting process. After the slotting is completed, the electric push rod 17 is activated to retract the clamping plate 18. At the same time, when the brush 29 is driven by the L-shaped plate 27 and the fixing block 28 to clean up the debris, it will not touch the mounting plate 16 and the clamping plate 18. During cleaning, the debris can enter the collection box 11 for collection and centralized treatment.

[0023] A support frame 3 is fixedly installed on the top surface of the workbench 1. A support frame 32 is installed below the support frame 3. A horizontal plate 36 is slidably installed on the bottom surface of the support frame 32. An ear plate 37 is fixedly installed on the bottom surface of the horizontal plate 36. A third motor 38 is installed on one side of the ear plate 37. A cutting wheel 39 is fixedly fitted on the output end of the third motor 38. A cylinder 31 is installed on the top surface of the support frame 3. The output end of the cylinder 31 is fixedly connected to the top surface of the support frame 32. A second motor 33 is installed on one side of the support frame 32. A lead screw 34 is fixedly installed on the output end of the second motor 33. A movable block 35 is fixedly installed on the top surface of the horizontal plate 36. The movable block 35 is threaded onto the outer surface of the lead screw 34.

[0024] By adopting the above technical solution, the cylinder 31 is activated, causing the support frame 32 to move down, allowing the cutting wheel 39 to approach the surface of the heat sink fins. At the same time, the third motor 38 is activated, causing the cutting wheel 39 to rotate and slot the surface of the heat sink fins. After slotting, the cylinder 31 is retracted, and the second motor 33 is activated, causing the lead screw 34 to rotate and the movable block 35 to drive the horizontal plate 36 to move. This allows the cutting wheel 39 to be adjusted, and the position of the heat sink fins to be cut can be adjusted as needed.

[0025] Working principle: First, the heat dissipation fins to be slotted are placed on the placement plate 14. The electric push rod 17 is activated, causing the clamping plate 18 to clamp and fix them. The cylinder 31 is activated, causing the support frame 32 to move downwards, allowing the cutting wheel 39 to approach the surface of the heat dissipation fins. Simultaneously, the third motor 38 is activated, causing the cutting wheel 39 to rotate and slot the surface of the heat dissipation fins. After slotting, the cylinder 31 retracts, and the second motor 33 is activated, causing the lead screw 34 to rotate. This causes the movable block 35 to move the horizontal plate 36, thereby adjusting the cutting wheel 39 to cut different positions of the heat dissipation fins as needed. After slotting is complete, the electric push rod 17 is activated again, and the cutting wheel 39 is retracted. When the clamping plate 18 is returned, and the brush 29 is driven by the L-shaped plate 27 and the fixing block 28 to clean up the debris, it will not touch the mounting plate 16 and the clamping plate 18. By turning on the first motor 21, the rotating shaft 22 drives the first bevel gear 23 to rotate. The first bevel gear 23 meshes with the second bevel gear 25, which in turn causes the threaded rod 24 to rotate, causing the threaded block 26 to drive the L-shaped plate 27 to move. At the same time, the brush 29 is driven to clean the surface of the placement plate 14 and remove the debris from the slotting process. This allows the next heat sink fin to be placed flat on the placement plate 14 when it is slotted, improving the quality of the heat sink fin slotting. During cleaning, the debris can enter the collection box 11 for collection and centralized processing.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
