Description

Technical Field

[0001] This utility model relates to the field of radiator processing technology, and specifically to a radiator surface treatment device. Background Technology

[0002] Aluminum alloy radiators are highly efficient heat dissipation products widely used in electronics, machinery, automobiles, and home appliances, renowned for their lightweight, high thermal conductivity, and excellent corrosion resistance. Their main materials are aluminum and aluminum alloys, which have low density and are lightweight, facilitating transportation and installation. For the same heat dissipation, their weight is only a fraction of that of cast iron or steel radiators. They are formed in one piece through extrusion and die casting processes, resulting in a stable structure without welds, avoiding the risk of leakage. The surface is anodized, enhancing not only corrosion and wear resistance but also aesthetic appeal. Their superior heat dissipation performance requires fewer fins than traditional radiators under the same conditions, resulting in significant energy savings. A dense oxide film can form on the aluminum alloy surface, allowing for long-term use in various water qualities and extending service life. Modular design allows for flexible installation; the number of fins can be increased or decreased to adapt to different heat dissipation requirements.

[0003] The prior art discloses a radiator processing and polishing mechanism, including a worktable, a fixedly installed work box on the worktable, symmetrical support platforms fixedly connected to the worktable, a perforated frame detachably installed on the support platforms, movable seats on both sides of the two support platforms, vertical frames on the two movable seats, a cross slide rail fixedly connected between the two vertical frames, a sliding sleeve that mates with the cross slide rail on the cross slide rail, a grinding tool fixedly connected below the sliding sleeve, a fixedly installed dust collection box below the worktable, suction fans communicating with the dust collection box on both sides of the dust collection box, suction pipes on the two suction fans, the suction pipes passing through the worktable and placed between the support platforms and the movable seats, and a main suction pipe on the dust collection box.

[0004] The aforementioned device uses mechanical grinding, which generates a lot of dust particles. Currently, another commonly used grinding method is magnetic grinding. However, after the existing magnetic grinding process, the abrasive mixes with the processed radiator, requiring workers to pick them out one by one. This is especially difficult for smaller radiators.

[0005] Based on this, the present invention designs a radiator surface treatment device to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a radiator surface treatment device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A radiator surface treatment device includes a grinding barrel and a frame for supporting the grinding barrel. The grinding barrel includes a barrel body, and a barrel cover is hinged to the upper end of the barrel body. The barrel body and the barrel cover are sealed by a sealing assembly. A screening assembly for separating the radiator and abrasive is installed inside the barrel cover. The frame includes a mounting frame, on which a rotating shaft is fixed. The mounting frame is also provided with a base plate. An electromagnetic component for driving the movement of the abrasive is installed at the lower end of the base plate. The base plate and the mounting frame are connected by a buffer component. The barrel body is hinged to the pivot, and the lower end of the barrel body is placed on the base plate.

[0008] Preferably, the buffer assembly includes a slide rail, a spring is sleeved around the slide rail, the upper end of the spring is a base plate, and the base plate is slidably connected to the mounting bracket.

[0009] Preferably, the slide rail on the side wall of the mounting bracket is adapted to the slider fixedly mounted on the base plate, and the slider slides along the long axis of the slide rail.

[0010] Preferably, the slider has a threaded hole on its side wall, and a fixing knob is installed in the threaded hole to brake the slider.

[0011] Preferably, the screening assembly includes a filter basket, which is detachably installed inside the barrel lid.

[0012] Preferably, a screw is installed through and fixedly mounted on the filter basket, and a connecting sleeve adapted to the screw is fixedly connected to the inner wall of the bucket cover.

[0013] Preferably, an arc-shaped strip for guiding material discharge is fixedly installed on the bucket lid near the position where it is hinged to the bucket body.

[0014] Preferably, the lower end of the mounting bracket is threaded with a pad.

[0015] Compared with the prior art, the advantages of this utility model are as follows: 1. By installing a filter basket inside the bucket lid, the grinding needle and radiator can be separated. Compared with the existing method of manually removing the radiator, the filter basket can separate the radiator from the mixture in one go, improving work efficiency. 2. A spring is fitted around the bottom edge of the slide rail. The lower end of the spring is fixedly installed on the slide rail, and the upper end of the spring is fixedly installed on the slider. The slider has a groove that matches the slide rail, and the two are slidably connected. At the same time, the slider is fixedly installed on the side wall of the base plate. When the base plate is compressed, the spring is compressed, and the base plate moves downward. 3. Considering that water will be added to the barrel during grinding to achieve cooling, a flow guide channel is fixedly installed on the inner edge of the barrel lid. The flow guide channel is arc-shaped. After the barrel body is reversed, the water, grinding needle and radiator inside it enter the barrel lid and are filtered by the filter basket. When the barrel lid rotates around the hinge point with the barrel body, the water inside it enters the flow guide channel and flows into the barrel body along the flow guide channel.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] Aluminum alloy heat sinks are commonly used heat conduction and dissipation devices for electronic components. They are generally attached to the surface of electronic components, conducting the heat generated during operation to a base plate and then further to dense fins. The fins have a large surface area, allowing heat to be conducted into the air, thus achieving heat dissipation. Current aluminum alloy heat sink production requires cutting a single piece of heat sink produced by extrusion or other processing methods into multiple ends. During cutting, burrs are inevitably generated at the cut surfaces, affecting the appearance of the finished product. Therefore, further processing is needed to remove these burrs. Magnetic grinding is a relatively mature deburring and polishing technology. It uses a motor to drive a high-powered magnetic disk and adds an energized coil to make the grinding needles inside the grinding barrel rotate at high speed. During this process, burrs are removed from the surface of the aluminum alloy heat sink. The inventors discovered that after the current magnetic grinding process, the polished aluminum alloy heat sink and grinding needles are mixed together, requiring manual removal of the heat sinks one by one from the grinding barrel, which is inefficient. Separating the grinding needles from the heat sink using a filtration device would improve the production efficiency of the heat sinks.

[0023] In some embodiments, please refer to the accompanying drawings. Figure 1 A surface treatment device for a radiator includes a polishing barrel 10, which serves as a place for accommodating and polishing the heat sink fins. The mechanism supporting the polishing barrel 10 is a frame 20, and the polishing barrel 10 can rotate on the frame 20.

[0024] Specifically, such as Figure 1 As shown, the main body of the polishing barrel 10 is the barrel body 11, which is a cylindrical structure with a sealed bottom at the bottom and an open top. A lid 12 is hinged to the opening, and the lid 12 covers the barrel body 11 to seal its upper opening. A rubber ring is fixedly adhered to the inner wall of the connection between the barrel body 11 and the lid 12. A sealing component, a sealing latch 112, is also fixedly installed on the outer walls of both parts. Figure 3 As shown, when the sealing latch 112 is closed, it applies pressure to the lid 12 and the body 11, keeping them closed and sealed. Furthermore, a filter basket 13 is installed inside the lid 12, and the structure of the filter basket 13 is as follows... Figure 4 As shown, its outer diameter is slightly smaller than the inner diameter of the lid 12. A screw 131 is vertically inserted and welded to the lower end of the filter basket 13. Correspondingly, a cylindrical connecting sleeve 121 is welded to the inner wall of the lid 12. The inner wall of the connecting sleeve 121 has a thread that matches the screw 131. The screw 131 is threadedly connected to the connecting sleeve 121. Therefore, the filter basket 13 can be detachably installed inside the lid 12 by the screw 131.

[0025] On the other hand, such as Figure 4As shown, water will be added to the barrel 11 during grinding to achieve cooling. A guide channel is fixedly installed on the inner edge of the barrel lid 12. The guide channel is arc-shaped. After the barrel 11 is reversed, the water, grinding needle and radiator inside it enter the barrel lid 12 and are filtered by the filter basket 13. When the barrel lid 12 rotates around the hinge point with the barrel 11, the water inside it enters the guide channel and flows into the barrel 11 along the guide channel.

[0026] The main body of the frame 20 is the mounting frame 21, which is a frame structure, such as... Figure 1 As shown, the lower end of the mounting bracket 21 is a foot 22, and one end of the rotating shaft 23 is rotatably mounted in the middle of the upper end. The other end of the rotating shaft 23 is fixedly mounted on the side wall of the barrel 11. The middle part is a base plate 24 for supporting the barrel 11. The base plate 24 can move up and down. An electromagnetic component is installed at the lower end of the base plate 24. The electromagnetic component includes a motor that drives the grinding needle to rotate and related components such as a high-power disk. This part of the device is a relatively mature existing technology and will not be described in detail here. Specifically, as shown... Figure 2 As shown, slide rails 14 are vertically fixedly installed on the side walls of the four legs of the mounting bracket 21. Each slide rail 14 has a smooth cylindrical side wall. A spring 141 is fitted around the lowermost periphery of the slide rail 14. The lower end of the spring 141 is fixedly installed on the slide rail 14, and the upper end of the spring 141 is fixedly installed on a slider 241. The slider 241 has a groove that matches the slide rail 14, and the two are slidably connected. Simultaneously, the slider 241 is fixedly installed on the side wall of the base plate 24. When the base plate 24 is compressed, the spring 141 compresses, and the base plate 24 moves downwards. Figure 2 As shown, a threaded hole is also opened on the side wall of the slider 241, which extends to the slide rail 14. A fixing knob 242 is installed in the threaded hole. When the fixing knob 242 is rotated, the threaded rod at its end contacts and presses against the slide rail 14, thereby constraining and fixing the slider 241 to the slide rail 14.

[0027] In use, first place the grinding needle and the radiator to be ground into the barrel 11, cover and seal the barrel 12, and start the device (the motor and hard disk drive on the device are existing technologies, installed at the lower end of the base plate 24, not shown in the figure). The grinding needle rotates inside the barrel 11 to grind the radiator. After the grinding work is completed, as follows... Figure 3 As shown, by releasing the constraint of the fixing knob 242 on the slider 241, the worker can step down on the base plate 24 to move it further downward, and then hold the handle 111 on the side wall of the barrel 11 and turn it upward to make it move according to... Figure 3Slowly rotate the barrel in the direction of rotation, and after reversing 180°, the staff holds the lid 12 and opens the sealing lock 112. At this time, the radiator and grinding needle in the barrel body 11 are transferred to the lid 12. Finally, the barrel body 11 is rotated further so that its bottom is placed on the base plate 24. The position of the base plate 24 is constrained by the fixing knob 242. At this time, the lid 12 is blocked by the barrel body 11 and keeps the opening facing upward in a vertical state.

[0028] During the process of rotating the barrel 11 and pouring the grinding needles and radiators inside the barrel 11 into the barrel lid 12, the mixture of grinding needles and radiators is filtered by the filter basket 13. During the process of rotating the filter basket 13 to remove it from the barrel lid 12, the grinding needles and radiators inside the filter basket 13 are vibrated. Smaller grinding needles fall out of the filter basket 13, while larger radiators remain inside the filter basket 13.

[0029] By installing a filter basket 13 inside the barrel lid 12, the grinding needle and the radiator can be separated. Compared with the existing method of manually removing the radiator, the filter basket 13 can separate the radiator from the mixture in one go, improving work efficiency.

[0030] In addition, when water is added for polishing, the water enters the lid 12 after the barrel body 11 rotates. Then, when the lid 12 rotates around the hinge point with the barrel body 11, the water inside it enters the guide channel and flows into the barrel body 11 along the guide channel.

[0031] Working principle: Hold the handle 111 on the side wall of the barrel 11 and turn it upwards to make it follow the direction of operation. Figure 3 The barrel is slowly rotated in the direction of rotation. After reversing 180°, the worker holds the lid 12 and opens the sealing lock 112. At this time, the radiator and grinding needles in the barrel body 11 are transferred into the lid 12. Finally, the barrel body 11 is rotated further so that its bottom is placed on the base plate 24. The position of the base plate 24 is constrained by the fixing knob 242. At this time, the lid 12 is blocked by the barrel body 11 and keeps the opening facing upward in a vertical state. During the process of rotating the barrel body 11 and pouring the grinding needles and radiator in the barrel body 11 into the lid 12, the mixture of grinding needles and radiator is filtered by the filter basket 13. During the process of rotating the filter basket 13 to remove it from the lid 12, the grinding needles and radiator in the filter basket 13 are vibrated. The smaller grinding needles fall out of the filter basket 13, while the larger radiator remains in the filter basket 13.
