Description

Technical Field

[0001] This invention relates to the field of radiator processing technology, and in particular to a precision grinding device for electronic radiators. Background Technology

[0002] Electronic heat sinks are mostly made of extruded aluminum profiles. These include CPU heat sinks, graphics card heat sinks, and power module heat sinks. The surface of the heat sink and the edges of the heatsink fins are prone to burrs, flash, knife marks, and oxide scale, requiring precision polishing to ensure surface smoothness, dimensional accuracy, and proper fit. Currently, polishing of electronic heat sinks largely relies on manual operation or simple polishing equipment, which has several technical drawbacks, as detailed below: Firstly, most existing grinding methods are rigid contact grinding, where the grinding tool makes hard contact with the surface of the heat sink, which can easily cause damage such as bumps, chipping, and over-grinding due to the irregular surface of the workpiece and positioning deviation. Secondly, the metal dust generated during the radiator grinding process tends to accumulate in the grinding area, which not only scratches the workpiece surface and reduces grinding accuracy, but also causes the grinding tools to wear out quickly and have a short lifespan. Direct dust overflow can also pollute the working environment, endanger the health of operators, and does not meet the requirements of environmentally friendly production. Summary of the Invention

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figures 1 to 9 : This invention proposes a precision polishing device for electronic heat sinks, comprising: a support housing 100, a collection housing 200 being snap-fitted into the support housing 100, an exhaust hole being opened on one side of the collection housing 200, an exhaust fan 120 being fixedly connected to one side of the exhaust hole, the exhaust fan 120 being located at the bottom of the collection housing 200, a set of mesh openings being opened at the bottom of the collection housing 200, and a set of drain holes being opened at the upper end of the support housing 100. The exhaust fan 120 generates negative pressure suction force when rotating, which collects the dust generated during the polishing of the heat sink in a timely manner. The mesh openings of the collection housing 200 filter impurities, and the drain holes of the support housing 100 discharge slag in a directional manner to avoid dust overflow and environmental pollution. In this embodiment, a set of fixedly connected robotic arms 300 are installed on the upper end of the support housing 100. A fixedly connected support frame 410 is installed on the end of the robotic arms 300. A first positioning frame 420 is slidably connected to one side of the support frame 410. Two sliding holes are opened on one side of the support frame 410. A set of fixedly connected first positioning rods 430 is provided on one side of the first positioning frame 420. The first positioning rods 430 pass through the interior of the sliding holes. A support spring is installed on the outside of the first positioning rods 430. The support spring elastically pushes the first positioning frame 420 outward, so that the first positioning frame 420 can float elastically, adapting to the grinding of radiators of different specifications, ensuring that the grinding sleeve 480 fits the workpiece surface, and avoiding rigid grinding. Radiator damage; A first electric motor 440 is fixedly connected to the outside of the first positioning frame 420. An insertion hole is opened inside the first positioning frame 420, and a rotating shaft is installed through the insertion hole. A cleaning fan 450 is fixedly connected to the outside of the rotating shaft. The end of the rotating shaft is fixedly connected to the drive shaft of the first electric motor 440. The first electric motor 440 drives the rotating shaft and the cleaning fan 450 to rotate. A pulley is installed at the end of the rotating shaft of the first electric motor 440 and the first positioning roller 460 respectively. A transmission belt is installed between the two pulleys. The pulleys connect the rotating shaft and the first positioning roller 460. When the rotating shaft rotates, it can drive the first positioning roller 460 to rotate simultaneously. In this embodiment, a first positioning roller 460 rotatably connected and a second positioning roller 470 slidably connected are installed at the end of the first positioning frame 420. Two rotating holes are formed at the end of the first positioning frame 420. One side of the first positioning roller 460 and the second positioning roller 470 respectively passes through the interior of the rotating holes. A grinding sleeve 480 is snapped between the first positioning roller 460 and the second positioning roller 470. The rotation of the first positioning roller 460 drives the second positioning roller 470 and the grinding sleeve 480 to rotate. The rotation of the grinding sleeve 480 precisely grinds the radiator. The support frame 410, the first positioning frame 420, the first positioning rod 430, the first electric motor 440, the cleaning fan 450, the first positioning roller 460, the second positioning roller 470, and the grinding sleeve 480 cooperate with each other. The polishing assembly 400 is composed of a first positioning roller 460 and a second positioning roller 470, each with a stepped shaft. A support spring is installed on the outside of the stepped shaft of the second positioning roller 470. The support spring pushes the second positioning roller 470 to position the polishing sleeve 480. By stretching the second positioning roller 470, the installation and removal of the polishing sleeve 480 can be facilitated. An exhaust hole is opened on one side of the first positioning frame 420. The exhaust hole has a V-shaped structure and decreases in size. The exhaust hole is connected to the insertion hole of the first positioning frame 420. The exhaust hole and the polishing sleeve 480 are aligned. When the cleaning fan 450 rotates, it generates a negative pressure airflow. The airflow passes through the exhaust hole and is concentrated and guided to the polishing sleeve 480, realizing the self-cleaning of the polishing sleeve 480, avoiding dust accumulation in the polishing area, and improving the polishing quality of the radiator. In this embodiment, a stabilizing plate 110 is fixedly connected at the corner of the supporting housing 100. A second electric motor 510 is fixedly connected to the bottom of the stabilizing plate 110. A slidingly connected movable frame 520 is installed at the upper end of the supporting housing 100. A cylinder 700 is fixedly connected to the upper end of the movable frame 520, and a second positioning frame 610 is installed at the bottom of the movable frame 520. A sliding groove is formed at the upper end of the supporting housing 100. The sliding groove has a U-shaped structure. The bottom of the movable frame 520 extends into the interior of the sliding groove. A rack 530 is fixedly connected to the outer side of the movable frame 520. The second electric motor 510, the movable frame 520, and the rack 530 cooperate to form a transverse drive mechanism 500. The drive shaft of the second electric motor 510 is mounted on the outer side of the sliding groove. A gear is installed, meshing with a rack 530. A second electric motor 510 drives the gear to rotate. When the gear rotates, it causes the rack 530 and the moving frame 520 to move laterally along the sliding groove, thereby causing the clamping mechanism 600 to move horizontally with the workpiece, adapting to the grinding and clamping requirements of radiators of different lengths. The upper end of the second positioning frame 610 is provided with a fixedly connected second positioning rod 611. The upper end of the moving frame 520 has a vertical sliding hole. The second positioning rod 611 passes through the interior of the sliding hole. The bottom of the cylinder 700 push rod is fixedly connected to the upper end of the second positioning frame 610. The cylinder 700 drives the second positioning frame 610 to rise and fall vertically, causing the clamping mechanism 600 to adjust up and down, thereby causing the clamping mechanism 600 to lift and lower the clamped radiator, adapting to the grinding requirements of radiators of different heights. In this embodiment, a third electric motor 620 is fixedly connected to one side of the second positioning frame 610. A threaded rod 630 is rotatably connected inside the second positioning frame 610. The threaded rod 630 has a bidirectional thread structure. Two symmetrically distributed clamping plates 640 are installed on the outside of the threaded rod 630. The second positioning frame 610, the second positioning rod 611, the third electric motor 620, the threaded rod 630, and the clamping plates 640 cooperate with each other to form a clamping mechanism 600. There are two clamping plates 640. A threaded hole is opened on one side of each clamping plate 640. The spiral directions of the two threaded holes are opposite. The threaded rod 630 is threadedly connected to the threaded hole. The third electric motor 620 drives the threaded rod 630 to rotate. When the threaded rod 630 rotates, it drives the two clamping plates 640 to move synchronously in opposite directions, so that the clamping plates 640 clamp or loosen the radiators of different sizes, preventing the radiators from shifting when the grinding sleeve 480 is grinding.

[0034] The working principle of this embodiment: When polishing the radiator using the polishing device, first place the support housing 100 stably on the worktable, and then install the collection housing 200 inside the support housing 100 for positioning; assemble the robot arm 300, polishing assembly 400, horizontal drive mechanism 500, clamping mechanism 600, and cylinder 700 according to the conventional steps. Place the electronic heat sink to be processed between the two clamping plates 640, start the third electric motor 620, and at this time the bidirectional threaded rod 630 drives the clamping plates 640 to move synchronously to clamp the heat sink. Next, according to the polishing requirements of the radiator, the cylinder 700 is activated. Guided by the second positioning rod 611, the cylinder 700 drives the second positioning frame 610 and the radiator to rise and fall vertically, adjusting the radiator to a position that matches the polishing sleeve 480. Next, the robotic arm 300 is activated to move the polishing assembly 400 above the radiator; the first positioning frame 420 floats elastically under the action of the support spring, so that the polishing sleeve 480 fits against the surface of the radiator. The first electric motor 440 is started to drive the grinding sleeve 480 and the cleaning fan 450 to rotate at high speed. The cleaning fan 450 generates airflow to blow away the waste debris from the grinding sleeve 480 for self-cleaning. At the same time, the exhaust fan 120 is turned on to generate negative pressure to collect the waste debris and dust. The second electric motor 510 is started to drive the moving frame 520 and the radiator to move laterally at a uniform speed to complete the precision grinding of the radiator. After the radiator is polished, cylinder 700 resets, and control clamping mechanism 600 releases the clamp on the radiator. The finished radiator is removed, replaced with a new radiator, and polished again. Dust and debris inside the housing 200 are cleaned and collected regularly.
