Description

Technical Field

[0001] This utility model belongs to the field of heat sink processing technology, specifically relating to a heat sink anodizing surface treatment equipment and the heat sink. Background Technology

[0002] A heat sink is a metal plate used for heat dissipation, typically installed on the heat sinks of electronic equipment or machines such as streetlights. It achieves heat dissipation by increasing its surface area, transferring heat from a heat source to the air. The working principle of a heat sink is based on the principles of heat transfer, meaning that heat transfer relies on thermally conductive materials and a heat transfer medium. The heat sink itself is made of thermally conductive metal, transferring heat from the heat source attached to the radiator or other heat dissipation device to itself, and then transferring the heat to the environment through its high surface area.

[0003] Anodizing of heat sinks is a surface treatment technology that improves the corrosion resistance, wear resistance and hardness of metals by forming an oxide film on the metal surface. After anodizing, all surfaces of the heat sink are covered with an oxide film. When the heat sink is in use, its heat sink base plate needs to be connected to the equipment and conduct electricity. Therefore, it is necessary to use surface treatment equipment to grind off the oxide layer on the outer surface of the heat sink base plate.

[0004] The existing surface treatment equipment has the following problems during use:

[0005] In the manufacturing process of heat sinks, the fine polishing of the oxide layer formed on the bottom surface still relies on manual loading one by one. This traditional manual loading method is not only inefficient and difficult to meet the fast-paced needs of large-scale production, but also requires operators to work continuously, which not only increases labor costs, but may also cause fatigue of operators due to long-term repetitive work, thereby affecting polishing quality and production efficiency. Utility Model Content

[0006] (1) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an anodizing surface treatment device for heat sinks and the heat sink itself. This surface treatment device aims to solve the technical problem that existing technologies still rely on manual loading of materials one by one. This traditional manual loading method is not only inefficient and difficult to meet the fast-paced demands of large-scale production, but also requires operators to work continuously, which not only increases labor costs but may also cause fatigue to operators due to long-term repetitive work, thereby affecting the grinding quality and production efficiency.

[0008] (2) Technical solution

[0009] To solve the above-mentioned technical problems, this utility model provides a heat sink anodizing surface treatment equipment and the heat sink. The equipment includes a main body, a grinding wheel, a treatment table, and a heat sink. The grinding wheel is installed on the inner wall of the main body, and the treatment table is installed through the interior of the main body. The surface of the treatment table is provided with a heat sink. A material trough is installed on the surface of the treatment table, and a conveyor belt is installed on the inner wall of the treatment table. A baffle is connected to the surface of the belt loop of the conveyor belt. A bracket is connected to the surface of the treatment table, and a limit strip is connected to the surface of the bracket. An anti-wear mechanism is fitted onto the surface of the treatment table.

[0010] When using the processing equipment of this technical solution, the conveyor belt drives the baffle to rotate through the belt on its surface. When the baffle moves, it will squeeze the heat sink on the bottom side. The heat sink can slide between the limit bar and the processing table when it is squeezed. When the heat sink continues to move laterally, it can slide to the bottom side of the grinding wheel. At this time, the outer surface of the heat sink can be polished by the rotation of the grinding wheel, thus removing the oxide layer on the outer surface of the heat sink.

[0011] Preferably, the horizontal dimension of the inner wall of the material trough matches the maximum lateral dimension of the heat sink. The material trough can be used to store heat sinks, thereby enabling automatic feeding of heat sinks through the squeezing of the baffle.

[0012] Furthermore, the limiting strips are symmetrically arranged on both sides of the processing table. The distance between the bottom side of the limiting strip and the upper surface of the processing table matches the size of the edge of the heat sink. The heat sink and the limiting strip are slidably connected. When the baffle moves, it will squeeze the bottom heat sink. The heat sink can slide between the limiting strip and the processing table when squeezed, which can limit the movement direction of the heat sink.

[0013] Furthermore, the distance between the two baffles is greater than the width of the heat sink when it is placed horizontally. This allows the heat sink to fall between the two adjacent baffles, thus facilitating the movement of the heat sink by squeezing it.

[0014] Furthermore, the wear-resistant mechanism includes a bracket, a round hole, a rotating rod, a conveyor wheel, and a protective ring. The bracket is connected to the edge of the upper surface of the processing table. A round hole is opened on the side surface of the bracket, and a rotating rod passes through the inside of the round hole. A conveyor wheel is connected to the surface of the rotating rod, and a protective ring is connected to the surface of the conveyor wheel.

[0015] Furthermore, the rotating rod forms a rotating structure with the bracket through the round hole, and the protective ring is made of silicone. The silicone protective ring can effectively prevent wear on the surface of the heat dissipation ear, thereby affecting the service life of the heat sink.

[0016] A heat sink includes a heat sink base plate, heat sink fins, and heat sink side ears. The heat sink base plate is connected to the surface of the heat sink fins, and heat sink side ears are connected to both ends of the heat sink base plate. The heat sink base plate, heat sink fins, and heat sink side ears are an integral structure.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. In this utility model, heat sinks are placed inverted positions into the inside of the material trough. When the conveyor belt runs, the belt on its surface rotates, which drives the baffle on its surface to rotate. When the baffle moves, it squeezes the bottom heat sink. The heat sink can slide between the limiting strip and the processing table under the pressure. When the heat sink continues to move laterally, it can slide to the bottom of the grinding wheel. At this time, the rotation of the grinding wheel can grind the outer surface of the heat sink base plate, which can remove the oxide layer on the outer surface of the heat sink base plate. This realizes automatic feeding of heat sinks during surface treatment, thereby improving the efficiency of heat sink surface treatment.

[0020] 2. In this utility model, the grinding wheel will squeeze the heat sink during the grinding process, and the baffle will also squeeze the heat sink. The combined force of the two forces can make the heat sink move laterally. During this process, the rotation of the protective ring can realize the transmission, and the flexibility of the protective ring can prevent the oxide layer on the surface of the heat sink ear from being worn, thereby improving the service life of the heat sink.

[0028] This specific embodiment is a heat sink anodizing surface treatment device and the heat sink, the structural schematic diagram of which is shown below. Figure 1-6 As shown, the processing equipment includes a main body 1, a grinding wheel 2, a processing table 3, and a heat sink 4. The grinding wheel 2 is installed on the inner wall of the main body 1, and the processing table 3 is installed through the interior of the main body 1. The surface of the processing table 3 is provided with heat sink 4. A material trough 5 is installed on the surface of the processing table 3, and a conveyor belt 6 is installed on the inner wall of the processing table 3. A baffle 7 is connected to the surface of the belt ring of the conveyor belt 6. A hanger 8 is connected to the surface of the processing table 3, and a limit strip 9 is connected to the surface of the hanger 8. An anti-wear mechanism 10 is fitted onto the surface of the processing table 3.

[0029] Among them, the horizontal dimension of the inner wall of the material tank 5 matches the maximum horizontal dimension of the heat sink 4, the limiting strip 9 is symmetrically arranged on both sides of the processing table 3, the distance between the bottom side of the limiting strip 9 and the upper surface of the processing table 3 matches the dimension at the edge of the heat sink 4, the heat sink 4 and the limiting strip 9 are slidably connected, and the distance between the two baffles 7 is greater than the width of the heat sink 4 when it is placed horizontally.

[0030] In addition, the wear-resistant mechanism 10 includes a bracket 1001, a circular hole 1002, a rotating rod 1003, a conveyor wheel 1004, and a protective ring 1005. The bracket 1001 is connected to the edge of the upper surface of the processing table 3. A circular hole 1002 is opened on the side surface of the bracket 1001. The rotating rod 1003 passes through the inside of the circular hole 1002. The conveyor wheel 1004 is connected to the surface of the rotating rod 1003. The protective ring 1005 is connected to the surface of the conveyor wheel 1004. The rotating rod 1003 forms a rotating structure with the bracket 1001 through the circular hole 1002. The protective ring 1005 is made of silicone.

[0031] A heat sink, the structural diagram of which is shown below. Figure 6 As shown, the heat sink includes a heat sink base plate 401, heat sink fins 402, and heat sink side ears 403. The heat sink base plate 401 is connected to the surface of the heat sink fins 402, and the heat sink side ears 403 are connected to both ends of the heat sink base plate 401. The heat sink base plate 401, heat sink fins 402, and heat sink side ears 403 are an integral structure.

[0032] Working principle: When using the device of this technical solution, firstly, the heat sink 4 is placed inverted into the inside of the material tank 5. Then, the conveyor belt 6 can be run. When the conveyor belt 6 runs, the belt on its surface will rotate. When the belt rotates, it can drive the baffle 7 on its surface to rotate. When the baffle 7 moves, it can squeeze the heat sink 4 at the bottom of the material tank 5. The heat sink 4 can move laterally under the pressure. When the heat sink 4 moves laterally, its heat dissipation side ear 403 can slide between the limit bar 9 and the processing table 3. The heat sink 4 continues to move laterally and can slide to the top of the anti-wear mechanism 10. When the heat sink 4 moves to the bottom of the grinding wheel 2, the rotation of the grinding wheel 2 can then be used to clean the heat dissipation base plate. The outer surface of 401 is polished to remove the oxide layer on the outer surface of the heat sink base plate 401. During the polishing process, the polishing wheel 2 will squeeze the heat sink 4, and the baffle 7 will also squeeze the heat sink 4. The combined force of the two forces can make the heat sink 4 move laterally. At the same time, the protective ring 1005 and the conveyor wheel 1004 drive the rotating rod 1003 to rotate inside the round hole 1002. During this process, the flexibility of the protective ring 1005 can prevent the oxide layer on the surface of the heat sink side ear 403 from being worn. Then, the polished heat sink 4 continues to slide on the surface of the processing table 3 under the pressure of the baffle 7, thereby realizing the automatic feeding of the heat sink 4 during surface treatment.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
