Description

Technical Field

[0001] This utility model relates to the field of heat sink processing technology, and more specifically, to a device for processing and polishing aluminum heat sinks. Background Technology

[0002] Aluminum heat sinks are aluminum products made from high-purity aluminum. After dozens of processing steps, they have a smooth, flat surface that is non-oxidizing and non-corrosive, and also possess good thermal conductivity, electrical insulation, and machinability. Since both sides of the aluminum heat sink require polishing, existing equipment can only operate on one side at a time. After one side is processed, it needs to be manually flipped before the other side can be polished. This not only reduces efficiency but also increases operational risks. To address these issues, a solution is proposed below. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide an aluminum heat sink processing and polishing device that can improve polishing efficiency while ensuring safety.

[0004] To solve the above problems, the present invention adopts the following technical solution.

[0005] A polishing device for aluminum heat sinks includes a base, a bracket fixedly connected above the base, and polishing components symmetrically arranged between the base and the bracket, with the polishing components arranged vertically symmetrically. Two polishing components are fixedly connected to the bracket and the base respectively, forming a polishing area between the two polishing components. A feeding plate is installed inside the bracket, and a first clamping member is installed on the feeding plate. A discharging plate is provided inside the bracket, and a second clamping member is installed on one side of the discharging plate. A feeding component is installed on the base, and the feeding component corresponds to the feeding plate.

[0006] Preferably, the first clamping member includes an electric telescopic rod, a pneumatic finger, and a clamping block. The electric telescopic rod is horizontally installed on the side of the loading plate. The pneumatic finger is installed at the output end of the electric telescopic rod and faces the grinding area. There are two clamping blocks arranged vertically. The two clamping blocks are respectively installed on the output end of the pneumatic finger. The second clamping member has the same structure as the first clamping member.

[0007] Preferably, the polishing assembly includes a polishing motor and a polishing head. The polishing motor is arranged vertically, and the polishing head is installed at the output end of the polishing motor, with the axis of the polishing head and the output end of the polishing motor being concentric.

[0008] Preferably, the feeding assembly includes a mounting frame, a limiting plate, a feeding cylinder, and a push plate. The mounting frame is mounted on the base and located on one side of the bracket. The mounting frame is in contact with the feeding plate, and the upper end face of the mounting frame is at the same height as the upper end face of the feeding plate. Two limiting plates are provided and are symmetrically arranged. The push plate is arranged between the two limiting plates and is in contact with the upper end face of the mounting frame. The push plate, the mounting frame, and the limiting plates are in sliding fit. The feeding cylinder is located on one side of the mounting frame, and the output end of the feeding cylinder is fixedly connected to the push plate.

[0009] Preferably, an inclined plate is provided below the second clamping member.

[0010] Preferably, a storage box is placed at one end of the inclined plate, and the storage box is placed on the base plate.

[0011] Preferably, a controller is mounted on the bracket, and the first clamping member, the second clamping member, and the feeding assembly are all electrically connected to the controller.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] I. This solution uses a first clamping component to hold one end of the aluminum heat sink, which then pushes the heat sink towards the grinding area. This avoids the inconvenience of manual movement and handling, improving safety. Two symmetrically arranged grinding components simultaneously grind both sides of the aluminum heat sink, increasing overall grinding efficiency. After grinding, the aluminum heat sink passes through the grinding area, where a second clamping component holds the ground portion. The first clamping component releases, and the second clamping component moves the aluminum heat sink, ensuring thorough grinding of the entire heat sink and preventing incomplete grinding, thus guaranteeing processing quality.

[0014] Second, the aluminum heat sink is gripped by pneumatic fingers and clamping blocks, avoiding the dangers of manual gripping. The movement of the pneumatic fingers is achieved by an electric telescopic cylinder, thereby moving the aluminum heat sink automatically without manual operation, ensuring safety and efficiency.

[0015] 3. The grinding head is driven by a grinding motor to rotate, and the rotating grinding head grinds the aluminum heat sink.

[0016] Fourth, the aluminum heat sink is limited by the limiting plate to ensure that the aluminum heat sink is pushed into the same position as the first clamping part. The feeding cylinder drives the push plate, and the push plate pushes the aluminum heat sink without the need for additional manual operation.

[0017] 5. The inclined plate is used to guide the finished aluminum heat sink to exit the blanking plate, thus playing a guiding role.

[0018] 6. The storage box serves to store the aluminum heat sinks that are discharged through the inclined plate, preventing them from scattering and facilitating subsequent handling.

[0019] VII. The controller plays a role in control and regulation. Attached Figure Description

[0027] Example 1:

[0028] Please see Figure 1-6A polishing device for aluminum heat sinks includes a base 1, a bracket 2 fixedly connected above the base 1, the bracket 2 being n-shaped, a controller 21 mounted on the top of the bracket 2, and polishing components 3 symmetrically arranged between the bracket 2 and the base 1. The polishing components 3 include polishing motors 13 and polishing heads 14. The polishing motors 13 are arranged vertically, and the polishing heads 14 are installed at the output end of the polishing motors 13, with the axis of the polishing heads 14 concentric with the output end of the polishing motors 13. Both polishing motors 13 are electrically connected to the controller 21, which controls the start and stop of the two polishing motors 13. The two polishing components 3 are arranged symmetrically, i.e., the two polishing heads 14 are close to each other, forming a polishing zone 4 between the two polishing heads 14. The two polishing motors 13, which are far apart from each other, are fixedly connected to the corresponding base 1 and bracket 2. By using the two polishing heads 14 arranged symmetrically to form the polishing zone 4, the aluminum heat sink passing through the polishing zone 4 can be polished on both sides simultaneously, improving polishing efficiency.

[0029] A feeding plate 5 is installed inside the bracket 2. The feeding plate 5 is horizontally arranged and fixedly connected to the inner side of the bracket 2. The upper end face of the feeding plate 5 is flush with the lower end face of the grinding area 4, thus facilitating the entry of the aluminum heat sink into the grinding area 4. The feeding plate 5 is C-shaped, and a first clamping member 6 is installed in the recess of the feeding plate 5. The first clamping member 6 includes an electric telescopic rod 10, a pneumatic finger 11, and a clamping block 12. The electric telescopic rod 10 is horizontally installed on the side of the feeding plate 5. The pneumatic finger 11 is installed at the output end of the electric telescopic rod 10 and faces the grinding area 4. There are two clamping blocks 12, which are arranged vertically. Both the pneumatic finger 11 and the electric telescopic rod 10 are electrically connected to the controller 21. Two clamping blocks 12 are respectively installed on the output end of the pneumatic finger 11. The feeding plate 5 supports the aluminum heat sink. By clamping one end of the aluminum heat sink through the pneumatic finger 11 and the clamping block 12, and moving it through the electric telescopic rod 10, the aluminum heat sink is automatically pushed to the grinding area 4 for grinding. There is no need for manual clamping and manual feeding. This not only ensures the stability of the aluminum heat sink during movement and makes the grinding degree of the aluminum heat sink uniform, but also effectively avoids the safety risks caused by manual operation. It is suitable for processing aluminum heat sinks of various sizes.

[0030] The bracket 2 has a feeding plate 7 inside. The feeding plate 7 is horizontally arranged and fixedly connected to the side of the bracket 2. The feeding plate 7 and the upper plate 5 are located on the same horizontal plane. When the aluminum heat sink passes through the grinding area 4, the feeding plate 7 will support one side of the aluminum heat sink. A second clamping member 8 is installed on one side of the feeding plate 7. The second clamping member 8, the first clamping member 6, and the grinding area 4 are located on the same straight line. The second clamping member 8 and the first clamping member 6 have the same structure. The second clamping member 8 is electrically connected to the controller 21, and the second clamping member 8 and the first clamping member 6 are arranged symmetrically. The second clamping member 8 can clamp one end of the aluminum heat sink that passes through the grinding area 4, thereby pulling the aluminum heat sink through the grinding area 4, thus achieving full grinding of the aluminum heat sink. The surface polishing prevents the aluminum heat sink from being partially unpolished due to the clamping action of the first clamping member 6. Simultaneously, a ramp 19 is provided below the second clamping member 8, which is fixedly connected to the base plate 1. When the second clamping member 8 removes its grip on the aluminum heat sink, the heat sink will fall onto the ramp 19 under its own weight, sliding down guided by the ramp 19. The ramp 19 prevents the aluminum heat sink from falling directly, acting as a buffer and guide. A storage box 20 is placed at one end of the ramp 19, which is placed on the base plate. The storage box 20 collects the aluminum heat sink that slides down from the ramp 19, preventing it from scattering after processing and requiring subsequent cleaning. The storage box 20 allows for direct collection, facilitating subsequent organization.

[0031] A feeding assembly 9 is installed on the base 1. A limiting plate is fixedly connected to the side of the feeding plate 5 away from the feeding assembly 9 to prevent the aluminum heat sink from falling off the feeding plate 5 due to inertia during feeding. The feeding assembly 9 includes a mounting bracket 15, a limiting plate 16, a feeding cylinder 17, and a push plate 18. The mounting bracket 15 is installed on the base 1 and is located on one side of the bracket 2. The mounting bracket 15 is in contact with the feeding plate 5. The upper end face of the mounting bracket 15 is at the same height as the upper end face of the feeding plate 5, which facilitates the movement of the aluminum heat sink onto the feeding plate 5 via the mounting bracket 15. Two limiting plates 16 are provided. The position plates 16 are symmetrically arranged. A baffle is provided at one end of the two position plates 16 near the first clamping member 6. There is a through groove between the baffle and the mounting bracket 15. The height of the through groove is higher than the thickness of one aluminum heat sink and lower than the thickness of two aluminum heat sinks. The push plate 18 is arranged between the two position plates 16. The upper end face of the push plate 18 and the mounting bracket 15 are in contact with each other. The push plate 18, the mounting bracket 15 and the position plates 16 are in sliding fit. The feeding cylinder 17 is located on one side of the mounting bracket 15. The output end of the feeding cylinder 17 is fixedly connected to the push plate 18 and the feeding cylinder 17 is electrically connected to the controller 21.

[0032] Working principle:

[0033] The user neatly stacks the aluminum heat sinks that need to be polished on the mounting bracket 15, and ensures that the left and right sides are neat by two limiting plates 16. The user starts the feeding cylinder 17 by the controller 21. The feeding cylinder 17 pushes the push plate 18. The thickness of the push plate 18 is less than the thickness of an aluminum heat sink. The push plate 18 pushes the aluminum heat sink at the bottom of the many aluminum heat sinks, pushes the aluminum heat sink through the groove, and then pushes it into the space between the two clamping blocks 12 via the feeding plate 5.

[0034] When the pneumatic finger 11 is activated, it drives the two clamping blocks 12 to clamp the aluminum heat sink. After clamping, the electric telescopic rod 10 will drive the pneumatic finger 11 to move, and the pneumatic finger 11 will drive the clamping blocks 12 to move. The two clamping blocks 12 will drive the aluminum heat sink to move and push the aluminum heat sink into the grinding area 4. The controller 21 will control the two grinding motors 13 to start. The two grinding motors 13 will drive the grinding head 14 to rotate. The two rotating grinding heads 14 will grind both sides of the aluminum heat sink at the same time, improving the grinding efficiency.

[0035] When the electric telescopic rod 10 of the first clamping member 6 reaches its maximum stroke, a portion of the aluminum heat sink remains unpolished by the polishing component 3. At this point, the second clamping member 8 clamps the already polished portion of the aluminum heat sink and polishes the unpolished portion, thus achieving complete polishing of the aluminum heat sink. Throughout the process, the first clamping member 6 and the second clamping member 8 are used to clamp the aluminum heat sink, eliminating the need for manual operation and ensuring processing safety. After the aluminum heat sink has completely passed through the polishing area 4, the second clamping member 8... The clamp on the aluminum heating element will loosen, and the aluminum heat sink will fall onto the inclined plate 19 under the action of gravity. The sliding speed of the aluminum heat sink is controlled by the friction between the inclined plate 19 and the aluminum heat sink. Guided by the inclined plate 19, the aluminum heat sink will eventually fall into the storage box 20. The storage box 20 collects the aluminum heat sink that has slid off the inclined plate 19, and the storage box 20 is placed on the base plate for easy movement, which facilitates the replacement of the new storage box 20 and the organization of the aluminum heat sink inside the old storage box 20.
