Description

Technical Field

[0001] This utility model relates to an edge removal mechanism, specifically an automatic edge removal mechanism for a heat dissipation substrate blank, belonging to the field of substrate processing technology. Background Technology

[0002] The heat dissipation substrate is the core of the thermal management system of electronic devices, playing a crucial role in rapidly dissipating heat from chips, especially indispensable in high heat flux density scenarios. During production, after processes such as cutting and stamping, the surface and edges of the raw material are prone to residual metal and burrs. These defects can disrupt heat conduction pathways, cause short circuits, or affect the fit accuracy with heat dissipation components. Therefore, these residues and burrs must be removed to ensure the performance stability and safety of the heat dissipation substrate. To address this, various edge-removing devices have been developed in the industry. For example, Chinese utility model patent CN221935578U discloses an edge-removing device for accessory manufacturing, specifically including a main body, a driven gear, and an elastic component. A fixing plate is fixedly connected to the top of the main body, a rotary motor is fixedly connected to the top of the fixing plate, and an adapter ring is fixedly connected to the side of the fixing plate away from the rotary motor. However, this device is more suitable for edge removal of circular workpieces and may be less suitable for edge removal of multi-shaped workpieces like heat dissipation substrates. Furthermore, the adjustable range of the edge removal angle and position is relatively small, resulting in limited adaptability. Utility Model Content

[0006] The aforementioned automatic edge trimming mechanism for the heat dissipation substrate blank has a first adjustment groove symmetrically arranged laterally on the fifth mounting plate; a threaded hole is provided on the sixth mounting plate, the threaded hole corresponding to the first adjustment groove; a second adjustment groove is symmetrically arranged vertically on the sixth mounting plate, through which a suction cup passes; a nut is threadedly connected to the suction cup, and the nut abuts against the top surface of the sixth mounting plate.

[0007] The aforementioned automatic edge trimming mechanism for heat dissipation substrate blanks includes a first mounting frame set on a workbench, second guide rails symmetrically arranged on the first mounting frame, a second slider slidably connected to the second guide rails, and the second slider being fixedly connected to the bottom of a fixing frame; a fourth motor is provided on the side of the first mounting frame, a first screw is provided at the output end of the fourth motor, a first nut block is provided on the first screw, and the first nut block is fixedly connected to the fixing frame.

[0008] The aforementioned automatic edge trimming mechanism for heat dissipation substrate blanks includes a fifth motor installed in a fixed frame. The output end of the fifth motor extends upward and is connected to a feeding plate. A second cylinder is installed on each side below the feeding plate. The extension and retraction ends of the second cylinders face outward and are equipped with blocks. The height of the blocks is lower than the height of the heat dissipation substrate blank.

[0009] The aforementioned automatic edge trimming mechanism for heat dissipation substrate blanks includes a vertical moving mechanism comprising a second mounting frame mounted on a worktable, a second mounting frame above the second mounting frame, a third guide rail symmetrically arranged on the second mounting frame, a third slider slidably connected to the third guide rail, and the third slider being fixedly connected to the bottom of the moving plate; a sixth motor is provided on the side of the second mounting frame, a second screw is provided at the output end of the sixth motor, a second nut block is provided on the second screw, and the second nut block is fixedly connected to the moving plate.

[0010] The aforementioned automatic edge trimming mechanism for heat dissipation substrate blanks includes a first auxiliary roller and a second auxiliary roller, which are coaxially arranged; the mesh count of the first auxiliary roller is greater than that of the second auxiliary roller.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, after the billet is fed in from the input conveyor belt, the feeding mechanism can transfer it to the unloading rotation mechanism, realizing automated connection of loading and unloading, reducing manual intervention, and improving processing efficiency. During the trimming process, the vertical moving mechanism moves the moving plate to adjust the distance between the trimming roller and the billet. The first motor drives the rotating frame to rotate around the shaft between the first mounting plates through the transmission between the first and second synchronous pulleys, thereby flexibly adjusting the trimming angle of the trimming roller to adapt to different shapes such as right angles and bevels on the edge of the billet. The second motor drives the trimming roller to rotate through the transmission between the fourth and third synchronous pulleys, providing stable power for the trimming operation and ensuring that burrs and residues are effectively removed. At the same time, the horizontal moving mechanism can drive the unloading rotation mechanism and the billet to move laterally, working with the trimming roller to achieve continuous trimming of the long side of the billet; the unloading rotation mechanism can drive the billet itself to rotate, and can perform trimming work on each side of the billet. The coordination of lateral movement and rotation enables the mechanism to adapt to the edge removal requirements of various heat dissipation substrate blanks, ensuring that all edges of the blanks are treated uniformly and thoroughly, thus improving edge removal quality and adaptability.

[0012] 2. In this utility model, the feeding mechanism drives the fifth synchronous wheel to rotate via a third motor, which in turn drives the sixth synchronous wheel via a synchronous belt. This drives the third mounting plate, which is fixed to the synchronous belt, to move laterally smoothly in cooperation with the first guide rail and the first slider. This allows the suction cups to align with the input conveyor belt, the unloading rotating mechanism, or the output conveyor belt, thus achieving orderly transfer of the blanks between various workstations. The suction cups are raised and lowered by the extension and retraction of the first cylinder, completing the picking and placing of the blanks. Furthermore, the bolts pass through the first adjustment groove of the fifth mounting plate and connect to the threaded hole of the sixth mounting plate. When the bolts slide in the first adjustment groove, the lateral spacing between the sixth mounting plates can be flexibly adjusted. By sliding the suction cups in the second adjustment groove of the sixth mounting plate and locking them with nuts, the longitudinal spacing of the suction cups on the same side can be adjusted. This allows for adaptation to different sizes of heat dissipation substrate blanks, ensuring that the suction cups can stably adsorb blanks of different specifications, thus improving the adaptability of this utility model.

[0013] 3. In this utility model, the edge removal roller adopts a combination structure in which the first auxiliary roller and the second auxiliary roller are coaxially arranged, and the mesh count of the first auxiliary roller is greater than that of the second auxiliary roller, so as to realize the step-like processing of the edge of the heat dissipation substrate blank: firstly, the second auxiliary roller with a lower mesh count is used for rough grinding to quickly remove obvious defects such as metal residue and large burrs from the edge of the blank. Then, the first auxiliary roller with a higher mesh count performs fine finishing on the edge after rough grinding, further removing fine burrs and smoothing the rough surface, so that the edge of the blank reaches the precision requirement of smoothness and flatness.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0017] Example: An automatic edge-removing mechanism for a heat dissipation substrate blank, configured as follows Figure 1-5 As shown, the system includes a workbench 1, which is made of HT300 gray cast iron, providing high overall rigidity. The surface undergoes aging treatment to eliminate internal stress, providing a stable mounting base for various mechanisms. An input conveyor belt 2 is located on the right side of the workbench 1 for continuously conveying the heat dissipation substrate blanks to be processed. An output conveyor belt 3 is located on the left side of the workbench 1 for conveying the finished blanks after edge trimming. A material feeding mechanism 4 is located in front of the workbench 1, such as... Figure 2 As shown, a transverse moving mechanism 5 is provided below the feeding mechanism 4. A fixed frame 6 is provided at the moving end of the transverse moving mechanism 5. The fixed frame 6 is welded from Q235 steel plate and is used to support the material feeding rotating mechanism 7. The material feeding rotating mechanism 7 is provided on the fixed frame 6. Figure 3 As shown, a vertical moving mechanism 8 is provided behind the horizontal moving mechanism 5. A moving plate 9 is provided at the moving end of the vertical moving mechanism 8. The moving plate 9 is made of 6061 aluminum alloy, which is lightweight and has good rigidity. First mounting plates 10 are symmetrically arranged on the moving plate 9, and a rotating frame 11 is rotatably connected between the first mounting plates 10 via deep groove ball bearings. A first motor 12 is provided on the moving plate 9, and a first synchronous pulley 13 is provided at the output end of the first motor 12. A second synchronous pulley 14 is provided on the rotating shaft of the rotating frame 11, and the second synchronous pulley 14 is connected to the first synchronous pulley 13 via a synchronous belt. A second mounting plate 15 is provided below the rotating frame 11, and the second mounting plates 15 are rotatably connected between each other via rolling bearings. A de-edge roller 16 is connected, and the rotating shaft of the de-edge roller 16 passes through the second mounting plate 15 and is connected to a third synchronous pulley 17. The de-edge roller 16 includes a first auxiliary roller 161 and a second auxiliary roller 162, which are coaxially arranged. The mesh count of the first auxiliary roller 161 is greater than that of the second auxiliary roller 162. During operation, the second auxiliary roller 162 with a lower mesh count first performs rough grinding, using the cutting force of the coarser abrasive to quickly remove obvious defects such as metal residue and large burrs from the edge of the blank. Then, the first auxiliary roller 161 with a higher mesh count uses fine abrasive to refine the edge after rough grinding, further removing fine burrs and smoothing the rough surface to achieve the required smooth and flat precision. Furthermore, when the edge-removing roller 16 removes metal residue and burrs from the edge of the blank through grinding, it generates metal dust and debris. A dust-collecting pipe, fixed to the fixed frame 6, is installed around the feeding rotation mechanism 7. The suction end of the dust-collecting pipe is aligned with the feeding plate 71, and the other end is connected to a negative pressure device to absorb the dust and debris. A second motor 18 is installed on the rotating frame 11. The output end of the second motor 18 is equipped with a fourth synchronous pulley 19, which is connected to a third synchronous pulley 17 via a synchronous belt, providing stable rotational power for the edge-removing roller 16. Figure 1 , Figure 2 and Figure 5As shown, the feeding mechanism 4 includes a first mounting frame 40 made of 6061 aluminum alloy profile. A first guide rail 41 is provided on the rear side of the first mounting frame 40. Two first sliders 42 are provided on the first guide rail 41. The clearance between the first sliders 42 and the first guide rail 41 is ≤0.01mm to ensure smooth sliding. A third mounting plate 43 is provided on the rear side of the first sliders 42, made of Q235 steel plate with a thickness of 8mm. A first cylinder 44 is provided on the rear side of the third mounting plate 43. A fourth mounting plate 45, made of the same material as the third mounting plate 43, is provided at the telescopic end of the first cylinder 44. A fifth mounting plate is horizontally arranged below the fourth mounting plate 45. 46, made of the same material as the third mounting plate 43, and a sixth mounting plate 47 is vertically symmetrically arranged below the fifth mounting plate 46, made of the same material as the third mounting plate 43, and the sixth mounting plate 47 is provided with multiple suction cups 48; a third motor 49 is provided on the rear side of the first mounting frame 40, and a fifth synchronous pulley 410 is provided through the output end of the third motor 49 passing through the first mounting frame 40; a sixth synchronous pulley 411 is provided on the rear side of the first mounting frame 40, and the sixth synchronous pulley 411 is located on the opposite side of the fifth synchronous pulley 410; the fifth synchronous pulley 410 is connected to the sixth synchronous pulley 411 via a synchronous belt, and the first slider 42 is fixedly connected to the synchronous belt. The fifth mounting plate 46 is symmetrically provided with first adjustment grooves 412 laterally; the sixth mounting plate 47 is provided with threaded holes 413, which correspond to the first adjustment grooves 412; the sixth mounting plate 47 is symmetrically provided with second adjustment grooves 414 vertically, through which the suction cup 48 passes; a nut 415 is threadedly connected to the suction cup 48, which abuts against the top surface of the sixth mounting plate 47, and the position of the suction cup 48 is fixed by the friction generated by tightening the nut 415. The feeding mechanism 4 drives the fifth synchronous wheel 410 to rotate through the third motor 49, and drives the sixth synchronous wheel 411 through the synchronous belt. The meshing transmission of the synchronous belt drives the third mounting plate 43, which is fixed to the synchronous belt, to move laterally smoothly under the guidance and constraint of the first guide rail 41 and the first slider 42, so that the suction cup 48 can be accurately aligned with the input conveyor belt 2, the unloading rotation mechanism 7 or the output conveyor belt 3, realizing the orderly transfer of the billet between each station. The first cylinder 44 extends and retracts, driving the suction cup 48 to rise and fall, completing the loading and unloading of the blank: when the suction cup 48 descends and contacts the blank, air is circulated to generate negative pressure to adsorb the blank; after rising, it moves to the target position and then descends again, breaking the vacuum to release the blank. Furthermore, a bolt passes through the first adjustment groove 412 of the fifth mounting plate 46 and connects to the threaded hole 413 of the sixth mounting plate 47. When the bolt slides within the first adjustment groove 412, the lateral spacing between the sixth mounting plates 47 can be flexibly adjusted, with an adjustment range of 50-300mm; by sliding the suction cup 48 within the second adjustment groove 414 of the sixth mounting plate 47 and locking it with a nut 415, the longitudinal spacing of the suction cups 48 on the same side can be adjusted, with an adjustment range of 30-200mm. This allows for adaptation to different sizes of the heat dissipation substrate blank, ensuring uniform force on the suction cup 48. Figure 4 As shown, the lateral movement mechanism 5 includes a first mounting frame 50 mounted on the workbench 1, welded from Q235 steel plate. Second guide rails 51 are symmetrically arranged on the first mounting frame 50, and a second slider 52 is slidably connected to the second guide rails 51. The second slider 52 is fixedly connected to the bottom of the fixed frame 6. A fourth motor 53 is located on the side of the first mounting frame 50. The output end of the fourth motor 53 is connected to a first screw 54 via a coupling. A first nut block 55, made of wear-resistant cast iron, is mounted on the first screw 54 with a clearance ≤0.02mm. The first nut block 55 is fixedly connected to the fixed frame 6. During operation, the fourth motor 53 drives the first screw 54 to rotate. The screw and the first nut block 55 are connected by threaded engagement to convert the rotational motion into linear motion. Simultaneously, the cooperation between the second guide rail 51 and the second slider 52 restricts the rotational freedom of the fixed frame 6, allowing it to move smoothly along the second guide rail 51. This drives the feeding rotation mechanism 7 and the billet to achieve lateral position adjustment, cooperating with the edge-removing roller 16 to complete edge-removing operations at different positions. like Figure 4 As shown, the feeding and rotating mechanism 7 includes a fifth motor 70 housed within a fixed frame 6. The output end of the fifth motor 70 extends upwards and connects to a feeding plate 71, which carries the blank. Second cylinders 72 are respectively located on each side below the feeding plate 71. The extension and retraction ends of the second cylinders 72 face outwards and are equipped with stops 73 made of polyurethane with a hardness of 80 Shore A to prevent scratching the blank. The height of the stops 73 is 5-10 mm lower than the height of the heat dissipation substrate blank. During operation, the fifth motor 70 drives the feeding plate 71 to rotate, causing the blank to rotate synchronously, ensuring that all edges of the blank are aligned with the trimming roller 16. After the blank is placed on the feeding plate 71, the second cylinders 72 extend, causing the stops 73 to move inwards, contacting the edges of the blank from all sides for positioning and clamping. The clamping range can be adjusted by the extension and retraction of the cylinders. The height of the stops 73 is lower than the height of the blank, preventing obstruction of the blank's edge to be trimmed area and ensuring that the trimming roller 16 can directly contact the area to be processed. Figure 3 As shown, the vertical moving mechanism 8 includes a second mounting frame 80 mounted on the worktable 1, welded from Q235 steel plate. Above the second mounting frame 80 is a second mounting frame 81, made of the same material as the first mounting frame 50. Symmetrically arranged on the second mounting frame 81 are third guide rails 82, and a third slider 83 is slidably connected to the third guide rails 82. The third slider 83 is fixedly connected to the bottom of the moving plate 9. A sixth motor 84 is located on the side of the second mounting frame 81. The output end of the sixth motor 84 is connected to a second screw 85 via a coupling. A second nut block 86 is mounted on the second screw 85 and fixedly connected to the moving plate 9. During operation, the sixth motor 84 drives the second screw 85 to rotate, converting the rotational motion into linear motion through the second nut block 86. This causes the moving plate 9 to move vertically under the guidance of the third guide rail 82 and the third slider 83, thereby adjusting the distance between the trimming roller 16 and the blank.

[0018] Working principle: After the billet is fed into the input conveyor belt 2, the third motor 49 of the feeding mechanism 4 drives the fifth synchronous wheel 410 to rotate. Through the synchronous belt and the sixth synchronous wheel 411, the third mounting plate 43 moves laterally in cooperation with the first guide rail 41 and the first slider 42, aligning the suction cup 48 with the input conveyor belt 2. The first cylinder 44 drives the suction cup 48 to descend, adsorb the billet, and then rises, moving above the unloading rotating mechanism 7 before lowering it to release the billet and complete the transfer, thus automating the loading and unloading process. During edge trimming, the sixth motor 84 of the vertical moving mechanism 8 drives the second screw 85 to rotate. Through the second nut block 86, the moving plate 9 moves under the guidance of the third guide rail 82 and the third slider 83, adjusting the distance between the edge trimming roller 16 and the billet. The first motor 12 drives the first synchronous wheel 13 to rotate, which in turn drives the second synchronous wheel 14 and the rotating frame 11 to rotate via the synchronous belt, flexibly adjusting the angle of the edge trimming roller 16 to adapt to the right angle, bevel, and other shapes of the billet edge. The second motor 18 drives the fourth synchronous pulley 19 to rotate, which in turn drives the third synchronous pulley 17 and the edge-removing roller 16 to rotate via a synchronous belt. At the same time, the fourth motor 53 of the lateral movement mechanism 5 drives the first screw 54 to rotate, which in turn drives the fixed frame 6 and the feeding rotation mechanism 7 to move laterally under the guidance of the second guide rail 51 and the second slider 52 via the first nut block 55. This allows the second auxiliary roller 162 with a lower mesh count to first rough grind away obvious residual material burrs, while the first auxiliary roller 161 with a higher mesh count is then finely ground to ensure smooth edges. The fifth motor 70 of the feeding rotation mechanism 7 drives the feeding plate 71 and the blank to rotate, and with the positioning of the stop block 73, each edge is aligned with the edge-removing roller 16 in sequence, thus achieving edge removal processing for all edges.
