Description

Technical Field

[0001] The utility model belongs to the field of radiator manufacturing, and in particular relates to an automatic grinding device for radiators. Background Art

[0002] As an indispensable component in electronic equipment, the radiator plays an important role in maintaining the stable operation of the system. It ensures that the equipment will not be damaged by overheating by efficiently transferring and dissipating the heat generated by electronic components. Especially in high-performance computing, data center servers, high-end gaming hardware, and various industrial control equipment, the performance of the radiator is directly related to the reliability and service life of the system. Among them, the skived radiator, with its unique structural design, increases the surface area to enhance the heat exchange capacity, becoming one of the key technologies to improve heat dissipation efficiency.

[0003] The grinding of skived heat sinks is a crucial part of the manufacturing process. The main purpose of grinding the heat sink end is to remove the oxide scale, dirt and fine burrs left over from the production process to ensure that the heat dissipation channel is unobstructed. This type of grinding plays a more cleaning and fine-tuning role, optimizing the air flow path and improving heat dissipation efficiency by removing obstacles at the microscopic level.

[0004] The grinding of the equipment surface focuses more on enhancing the heat conduction efficiency between the heat source and the heat source by changing the surface roughness and microstructure, and is more conducive to bonding with the equipment. A good contact surface can fit the heat source more closely, reduce the thermal resistance between the two, and accelerate the transfer of heat from the heat source to the heat sink. The automatic grinding device can accurately control the grinding depth and mode to create a microstructure that is conducive to heat conduction, such as adding tiny protrusions to increase the actual contact area, or forming a texture that is conducive to the distribution of thermal grease, thereby greatly improving the heat dissipation effect.

[0005] However, most of the existing skived-tooth heat sink grinding processes rely on manual operation, which brings many problems and challenges. First of all, manual grinding operations are labor-intensive and inefficient, and it is difficult to meet the needs of large-scale production. Operators need to hold grinding tools for a long time, which is not only time-consuming and labor-intensive, but also easily leads to worker fatigue and occupational health problems. Secondly, the uniformity and precision of manual grinding are limited, and it is difficult to ensure the consistency of each product, which affects the overall performance and quality stability of the heat sink, resulting in uneven thermal conductivity performance. In addition, manual operation is difficult to achieve high-precision surface treatment standards, especially when dealing with skived-tooth structures with complex geometries, which often leave grinding marks or inadequate processing, affecting the heat dissipation efficiency and aesthetics of the final product.

DETAILED DESCRIPTION

[0036] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0037] Implementation example 1:

[0038] like Figure 1 As shown, a heat sink automatic polishing device is provided with a housing 200 on a transmission track 100, and automatically polishes a heat sink 1200 in the housing 200, which can be used as a separate polishing process or as one of the automatic processes on a production line. The transmission track 100 is used as a transport carrier for the equipment to be processed, and the heat sink 1200 is carried forward in the processing direction by the continuous advancement of the surface.

[0039] like Figure 2-3 As shown, the limiting structure 1100 intercepts the radiator 1200 in the housing 200. The limiting structure 1100 includes a limiting block 1110 and a limiting driving device 1120. The limiting driving device 1120 can drive the limiting block 1110 to extend and retract on the surface of the transmission track 100 to intercept the radiator 1200 at the target position and release the radiator 1200 after the processing is completed. In this embodiment, the limiting driving device 1120 is a cylinder structure, the cylinder body is fixed on the back of the transmission track, the piston rod is connected to the limiting block, and the limiting block 1110 is driven to move by telescoping.

[0040] The vertical drive device 300 is arranged on the upper end surface of the housing 200. In this embodiment, the vertical drive device 300 is a cylinder structure. The cylinder body is fixed on the housing 200. The piston rod extends downward inside the housing to connect to the lower pressing frame 400, driving the lower pressing frame 400 to move in the vertical direction. The lower pressing frame 400 is provided with protrusions 410 on both sides. The protrusions 410 match the vertical slide grooves 210 on the inner wall of the housing. Under the drive of the vertical drive device 300, the protrusions 410 move up and down in the vertical slide grooves 210. Figure 4As shown, the translation frame 500 is connected below the lower pressing frame 400, the first driving device 600 is connected to the side of the lower pressing frame 400, and in this embodiment, the first driving device 600 is a cylinder structure, and the piston rod is telescopic to drive the translation frame 500 to move in the horizontal direction. The two ends of the translation frame 500 extend downward, and the slide bar 700 is connected between the extended parts. The second driving device 800 is connected to the side of the translation frame 500, and the grinding structure 900 is connected to the slide bar 700. In this embodiment, the second driving device 800 is a cylinder structure, and the piston rod is telescopic to drive the grinding structure 900 to move along the slide bar 700. The moving direction of the translation frame 500 is perpendicular to the moving direction of the grinding structure 900 in the horizontal direction, so that the position adjustment of the grinding structure 900 in the horizontal direction is realized.

[0041] The grinding structure 900 includes a grinding base 910 movably connected to the slide bar 700, a rotating drive device 920 connected to the grinding base 910, and a grinding device 930 connected to the lower end surface of the rotating drive device 920. The rotating drive device 920 drives the grinding device 930 to rotate at high speed to grind the upper end surface of the radiator 1200. In order to facilitate the replacement and maintenance of the grinding device, the grinding device 930 and the rotating drive device 920 are detachably connected. In this embodiment, the grinding device 930 is a brush, which is mainly used to clean the upper end of the heat sink of the skived radiator, remove the oxide scale, dirt and fine burrs remaining in the production process, and ensure that the heat dissipation channel is unobstructed. This type of grinding plays a more cleaning and fine-tuning role. By removing obstacles at the microscopic level, it optimizes the air flow path and improves the heat dissipation efficiency.

[0042] like Figure 5 As shown, the clamping structure 1000 includes two "L"-shaped clamping blocks 1010 correspondingly arranged on both sides of the transmission track 100, a clamping vertical drive device 1020 connected to the clamping block 1010, and a clamping horizontal drive device 1030 connected to the clamping vertical drive device 1020; the horizontal part of the "L"-shaped clamping block 1010 is embedded in the transmission track 100, and the vertical part 1012 is erected on both sides of the transmission track 100; the clamping vertical drive device 1020 is arranged in the horizontal moving track 1040, and is driven by the clamping horizontal drive device 1030 to move in the horizontal moving track 1040, approaching and moving away from each other, clamping and releasing the radiator 1200 to be polished. In this embodiment, the clamping vertical drive device 1020 and the clamping horizontal drive device 1030 are cylinder structures, and the corresponding components are driven to move by the extension and contraction of the piston rod.

[0043] like Figure 6As shown, during grinding, the limit block 1110 protrudes to intercept the radiator 1200 in the housing 200, the clamping vertical drive device 1020 drives the clamping block 1010 to extend to lift the radiator 1200 from the transmission track 100 by one end, and the clamping horizontal drive device 1030 drives the vertical part 1012 to clamp the radiator 1200 from both ends, ensuring the stable clamping of the radiator 1200 during the grinding process. The vertical drive device 300 drives the lower pressure frame 400 to move downward to the grinding position, and the first drive device 600 and the second drive device 800 continuously adjust the position of the grinding device 930 to grind the upper end surface of the radiator 1200. After grinding is completed, the horizontal part 1011 returns to the surface of the transmission track 100, the limit block 1110 retracts, and the radiator 1200 continues to move forward on the transmission track 100.

[0044] Implementation Example 2:

[0045] Compared with the first embodiment, in this embodiment, only the grinding device 930 is replaced with emery cloth while the other structures remain unchanged.

[0046] like Figure 7 As shown, the polishing device of this embodiment polishes the fitting surface of the heat sink 1200 and the device, and enhances the heat conduction efficiency between the heat source and the heat source by changing the surface roughness and microstructure. A good contact surface can fit the heat source more closely, reduce the thermal resistance between the two, and accelerate the transfer of heat from the heat source to the heat sink. The automatic polishing device can accurately control the polishing depth and pattern to create a microstructure that is conducive to heat conduction, such as adding tiny protrusions to increase the actual contact area, or forming a texture that is conducive to the distribution of thermal grease, thereby greatly improving the heat dissipation effect and improving the fit between the device and the heat sink.

[0047] The control system receives a preset processing program or real-time operation instruction, and accurately controls the operation of the vertical drive device 300, the first translation drive device 600, the second translation drive device 800, and the rotation drive device 920, ensuring that the grinding structure can move and rotate according to the predetermined trajectory and force, so as to achieve efficient and accurate grinding of the upper end surface of the radiator. This precise control is crucial to ensure the grinding quality and avoid over-grinding or under-grinding.

[0048] By controlling the limiting structure 1100, the limiting block 1110 can be extended in time to intercept the radiator, ensuring that the workpiece is correctly in place and automatically released at the appropriate time before or after grinding, thereby realizing an automated feeding and unloading process, reducing human intervention, and improving operation continuity and safety.

[0049] The control system accurately coordinates the actions of the clamping vertical drive device 1020 and the clamping horizontal drive device 1030, so that the "L"-shaped clamping block 1010 can accurately lift, clamp the radiator and move smoothly, ensuring that the radiator remains stable during the entire grinding process and avoiding grinding quality problems caused by workpiece shaking.
