Description

[0001] The present invention relates to the technical field of mesh heat sink processing, and in particular to a high-density mesh heat sink opening processing technology and processing equipment. Background Art

[0002] High-density mesh heat sinks are specially designed for efficient heat dissipation. They feature numerous tiny holes that increase the heat dissipation area and facilitate air circulation, thereby improving heat dissipation efficiency. In electronic devices, especially for components with high heat flux densities such as high-power processors and lasers, using high-density mesh heat sinks can effectively reduce operating temperatures, ensuring stable operation and extending the lifespan of the equipment.

[0014] A processing technology for high-density mesh heat sink opening processing equipment includes the following steps: Step 1: Place the heat sink to be drilled on the processing table so that one end and one side are respectively aligned with the end and side wall of the processing table. Adjust the position of the T-shaped plate and the limit plate so that they are respectively aligned with the other end and the other side of the heat sink to complete the positioning; Step 2: The lifting assembly drives the synchronous drilling mechanism to move up and down, and the XY axis moving mechanism drives the drilling mechanism to move equidistantly along the X axis direction, drilling holes on the heat sink according to the triangular forward method; Step 3: The XY axis moving mechanism drives the synchronous hole opening mechanism to move along the Y axis direction. During the movement, the rotating mechanism is used to drive the synchronous hole opening mechanism to rotate 180 degrees as a whole. Step 4: Control the movable sleeve to move along the X-axis direction for fine adjustment so that the hole it drills is flush with the hole drilled at the end of the previous row. Continue to use the XY-axis moving mechanism to drive the drilling mechanism to move equidistantly along the X-axis direction. Repeat the operation until all the holes in the heat sink are drilled.

[0015] Beneficial effects of the present invention: 1. In the present invention, the XY axis moving mechanism is used to precisely control the movement of the movable sleeve along the X axis or Y axis as needed, and the lifting assembly is used to conveniently control the lifting and lowering of the synchronous hole-drilling mechanism. During the descent process, the synchronous hole-drilling mechanism is used to facilitate drilling three holes on the heat sink each time, which not only improves the hole-drilling efficiency, but also arranges the three holes in a triangular layout, which can avoid stress concentration on a certain line, thereby reducing the situation of excessive local stress. Since the holes are no longer drilled in the traditional sequence, but drilled in a triangular forward manner, the deformation caused by stress conduction and accumulation due to linear sequential drilling can be avoided.

[0016] 2. In the present invention, the rotating mechanism facilitates the synchronous hole-drilling mechanism to rotate 180 degrees as a whole when moving along the Y-axis direction, thereby facilitating the adjustment of the drill position and further enhancing the stress dispersion effect. When the subsequent drilling mechanism continues to move along the Y-axis direction, it rotates 180 degrees to reset. This method not only makes the holes opened on the heat sink evenly distributed, but also makes the axis connection line of any three adjacent holes on the heat sink form a triangle. The triangle is one of the most stable geometric shapes. Therefore, this layout can enhance the heat sink's ability to resist external stress and reduce the possibility of deformation.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0021] As Figure 1-10 shown, the present invention is an equipment for processing holes in a high-density mesh heat dissipation plate, including a processing table 1 and an X-Y axis moving mechanism 2. A drilling mechanism 4 for opening holes in the heat dissipation plate 3 is installed on the X-Y axis moving mechanism 2; the drilling mechanism 4 includes a moving sleeve 41, a lifting component 42, a synchronous hole opening mechanism 43 and a rotating mechanism 44. The X-Y axis moving mechanism 2 is used to drive the moving sleeve 41 to move along the X-Y axis direction. The synchronous hole opening mechanism 43 is connected to the moving sleeve 41 through the lifting component 42. The synchronous hole opening mechanism 43 synchronously drills three holes on the heat dissipation plate 3 each time, and the connecting line of the axes of the three holes is triangular. The rotating mechanism 44 is installed between the synchronous hole opening mechanism 43 and the X-Y axis moving mechanism 2, and the rotating mechanism 44 is used to drive the synchronous hole opening mechanism 43 to rotate itself when the moving sleeve 41 moves along the Y axis direction.

[0022] It should be noted that during use, the heat dissipation plate 3 to be drilled is positioned and placed on the processing table 1. The position of the drilling mechanism 4 is adjusted by the X-Y axis moving mechanism 2 so that the synchronous hole-opening mechanism 43 is located at the corresponding initial position above the heat dissipation plate 3. The lifting component 42 is used to control the lifting of the synchronous hole-opening mechanism 43. During the descending process, the three holes arranged in a triangular layout can be drilled on the heat dissipation plate 3 at one time by using the activated synchronous hole-opening mechanism 43. The moving sleeve 41 is controlled to move equidistantly along the X-axis direction until all the holes in the X-axis direction are completed; Subsequently, the moving sleeve 41 is controlled to move along the Y-axis direction. During the moving process, the synchronous hole-opening mechanism 43 is rotated 180 degrees by the rotating mechanism 44. Finally, the equidistant moving and hole-opening along the X-axis direction are repeated before. By repeating this process, all the holes in the heat dissipation plate 3 can be completed.

[0023] As Figure 2 and Figure 4 shown, it can be understood that the specific structure of the X-Y axis moving mechanism 2 and its installation method are not limited in this application. Only a specific structure is provided for reference below. The X-Y axis moving mechanism 2 includes an X-axis linear guide rail 21, an X-axis linear motor 22, a U-shaped seat 23, a longitudinal beam 24, a Y-axis linear guide rail 25, and a Y-axis linear motor 26. The two X-axis linear guide rails 21 are symmetrically arranged on the top of the processing table 1 along the length direction of the processing table 1. The X-axis linear motor 22 is slidably connected to the X-axis linear guide rail 21. The U-shaped seat 23 is installed on the top of the X-axis linear motor 22. The longitudinal beam 24 is installed between the two U-shaped seats 23. The Y-axis linear guide rail 25 is installed on one side of the longitudinal beam 24. The Y-axis linear motor 26 is slidably connected to the Y-axis linear guide rail 25. The moving sleeve 41 is fixedly sleeved outside the Y-axis linear motor 26, and the moving sleeve 41 is slidably sleeved with the longitudinal beam 24.

[0024] It should be noted that the X-axis linear motor 22 cooperating with the X-axis linear guide rail 21 facilitates the precise movement of the moving sleeve 41 in the X-axis direction, and the Y-axis linear motor 26 cooperating with the Y-axis linear guide rail 25 facilitates the precise movement of the moving sleeve 41 in the Y-axis direction.

[0025] As Figure 2-3 shown, the lifting component 42 includes a cylinder 421, an inverted L-shaped plate 422, and a C-shaped plate 423. The inverted L-shaped plate 422 is installed on the top of the moving sleeve 41. The cylinder 421 is installed on the top of the inverted L-shaped plate 422, and the piston rod of the cylinder 421 penetrates through the top of the inverted L-shaped plate 422 and is connected to the C-shaped plate 423. The horizontal part below the C-shaped plate 423 is located below the moving sleeve 41.

[0026] It should be noted that the vertical part of the C-shaped plate 423 is in contact with one side of the moving sleeve 41. Starting the cylinder 421 facilitates controlling the C-shaped plate 423 to lift along the moving sleeve 41.

[0027] As Figure 2-3 and Figure 5-6 As shown in Figure 5-6 , the synchronous hole-opening mechanism 43 includes an upper turntable 431, a lower turntable 432, a fixed rod 433, a rotary motor 434, a main gear 435, a sub-gear 436, a main shaft 437, and a drill bit 439 with a groove 438. The lower turntable 432 is rotatably installed on the horizontal part below the U-shaped plate 423, and the lower turntable 432 is connected to the upper turntable 431 above by multiple fixed rods 433. The three main shafts 437 are all rotatably connected to the lower turntable 432. The drill bit 439 is installed at the bottom end of the main shaft 437, and the groove 438 is provided at the bottom of the drill bit 439. The sub-gear 436 is sleeved at a position near the top end of the main shaft 437. The rotary motor 434 is installed at the bottom of the upper turntable 431. The main gear 435 is driven by the rotary motor 434, and the main gear 435 meshes with the three sub-gears 436 respectively.

[0028] It should be noted that when the rotary motor 434 drives the main gear 435 to rotate, the three main shafts 437 installed with the sub-gears 436 can be driven to rotate synchronously. The drill bit 439 is detachably connected to the main shaft 437. The groove 438 provided at the bottom of the drill bit 439 can effectively reduce its contact area with the heat dissipation plate 3, thereby reducing the heat generated by friction during drilling.

[0029] As Figure 2-3 and Figure 10 shown in Figure 10 , the rotating mechanism 44 includes a rack 441, a transmission gear 442, an L-shaped frame 443, a convex plate 444, and a telescopic member 445. The convex plate 444 is installed on one side of the moving seat 41. The telescopic member 445 is rotatably connected to the convex plate 444, and the bottom end of the telescopic member 445 is connected to the synchronous hole-opening mechanism 43. The rack 441 is connected to the U-shaped seat 23 through the L-shaped frame 443. The transmission gear 442 is meshed with the rack 441, and the transmission gear 442 is sleeved outside the telescopic member 445.

[0030] It should be noted that the telescopic member 445 can not only telescopically extend along its axis, but also achieve overall synchronous radial rotation. When the moving seat 41 moves along the Y-axis, it will drive the transmission gear 442 to move along the length direction of the rack 441, so that the telescopic member 445 drives the overall synchronous rotation of the synchronous hole-opening mechanism 43. To ensure the uniformity of the holes in the heat dissipation plate 3, the distance between each of the three holes drilled each time is equal (this distance is set as a), that is, the axis connection of the three holes forms an equilateral triangle. Therefore, the distance that the moving seat 41 moves equidistantly along the X-axis each time is set as b, and after moving the distance b, one of the three holes drilled can still form an equilateral triangle with side length a with two of the three holes drilled previously. The distance that the moving seat 41 moves equidistantly along the Y-axis each time is set as c, and after moving the distance c, it drives the overall rotation of the synchronous hole-opening mechanism 43 by 180 degrees. Since the three holes drilled after moving the distance c along the Y-axis cannot be flush with the three holes drilled at the end of the previous row, it is necessary to control its fine adjustment along the X-axis (the fine adjustment distance is set as d). After fine adjustment and leveling, the axis connection of three adjacent holes in adjacent rows can form an equilateral triangle with side length a. Among triangles, an equilateral triangle has the best stability, which is beneficial to improving the stability of the overall structure of the heat dissipation plate 3.

[0031] As Figure 3 shown, the lifting component 42 further includes a guide sleeve 424 and a guide rod 425. The two guide rods 425 are symmetrically installed at the top of the moving sleeve 41, and the two guide sleeves 424 are symmetrically installed at one end of the horizontal part above the U-shaped plate 423, and the guide sleeve 424 is slidably sleeved with the guide rod 425.

[0032] It should be noted that during the lifting process of the U-shaped plate 423, it is guided and lifted along the guide rod 425 through the guide sleeve 424, thereby improving the stability of the lifting of the U-shaped plate 423.

[0033] As Figure 3 and Figure 9 shown, the telescopic member 445 includes an outer tube 4451 and an inner sliding rod 4453 with a limiting key 4452. The inner sliding rod 4453 is slidably inserted into the outer tube 4451, and a limiting groove for the limiting key 4452 to slide is provided on the inner tube wall of the outer tube 4451.

[0034] It should be noted that the cooperation of the limiting key 4452 and the limiting groove enables the outer tube 4451 to drive the inner sliding rod 4453 to rotate synchronously when the outer tube 4451 rotates.

[0035] As Figure 1-2 shown, a T-shaped plate 5 that fits one end of the heat dissipation plate 3 is slidably installed in the processing table 1, and a limiting plate 6 that fits one side of the heat dissipation plate 3 is slidably installed on the T-shaped plate 5. A first locking component is installed between the T-shaped plate 5 and the processing table 1, and a second locking component is installed between the limiting plate 6 and the T-shaped plate 5.

[0036] It should be noted that the use of the position-adjustable T-shaped plate 5 and the limit plate 6 not only facilitates the stable limiting of the heat sink 3 in the processing table 1 so that position displacement does not occur during the hole opening process, but also facilitates adaptation to heat sinks 3 of different sizes and models, and has good applicability.

[0037] like Figure 7-8 As shown, the first locking assembly includes a transverse notch 51, a transverse pressure plate 53 with a first through-slot 52, a first threaded protrusion 54, and a first knob 55. The two transverse notches 51 are symmetrically arranged on the top of the processing table 1. The ends of the T-shaped plate 5 extend into the transverse notch 51. The transverse pressure plate 53 covers the transverse notch 51. The first threaded protrusion 54 passes through the first through-slot 52 and is installed on the upper surface of the end of the T-shaped plate 5. The first knob 55 is threadedly sleeved with the first threaded protrusion 54. The second locking assembly includes a longitudinal notch groove 61, a longitudinal pressure plate 63 with a second through groove 62, a second threaded protrusion 64 and a second knob 65. The longitudinal notch groove 61 is opened at the top of the T-shaped plate 5, one end of the limiting plate 6 extends into the longitudinal notch groove 61, the longitudinal pressure plate 63 covers the longitudinal notch groove 61, the second threaded protrusion 64 passes through the second through groove 62, and the second threaded protrusion 64 is installed on the top of the limiting plate 6, and the second knob 65 is threadedly connected with the second threaded protrusion 64.

[0038] It should be noted that, push the T-shaped plate 5 to slide along the horizontal notch groove 51, and after it fits with one end of the heat sink 3, tighten the first knob 55 to lock its position, push the limit plate 6 to slide along the longitudinal notch groove 61, and after it fits with one side of the heat sink 3, tighten the second knob 65 to lock its position.

[0039] A processing technology for high-density mesh heat sink opening processing equipment includes the following steps: Step 1: Place the heat sink 3 to be drilled on the processing table 1 so that one end and one side are respectively in contact with the end and side wall of the processing table 1. Adjust the positions of the T-shaped plate 5 and the limiting plate 6 so that they are respectively in contact with the other end and the other side of the heat sink 3 to complete the positioning. Step 2: The lifting assembly 42 drives the synchronous drilling mechanism 43 to move up and down, and the XY axis moving mechanism 2 drives the drilling mechanism 43 to move equidistantly along the X axis direction, drilling holes on the heat sink 3 according to the triangular forward method; Step 3: The XY axis moving mechanism 2 drives the synchronous hole opening mechanism 43 to move along the Y axis direction. During the movement, the rotating mechanism 44 drives the synchronous hole opening mechanism 43 to rotate 180 degrees as a whole. Step 4: Control the movable sleeve 41 to move and fine-tune along the X-axis direction so that the hole it punches is flush with the hole punched at the end of the previous row. Continue to use the XY-axis moving mechanism 2 to drive the drilling mechanism 43 to move equidistantly along the X-axis direction. Repeat the operation until all the holes in the heat sink 3 are completed.

[0040] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
