Description

Technical Field

[0001] This invention relates to a flat cutting processing equipment for heat dissipation substrates, belonging to the technical field of processing equipment. Background Technology

[0002] As the core carrier of the thermal management system of electronic devices, the heat dissipation substrate plays a crucial role in rapidly dissipating heat from chips. Copper, due to its high thermal conductivity and cost advantages, has become the preferred material for high-end heat dissipation substrates in 5G base stations, new energy vehicle electronic control modules, and other applications. Industrial-grade copper is typically stored and transported in coils. While this method ensures transportation efficiency, it inevitably introduces plastic deformation and residual stress. After uncoiling, the copper sheet exhibits wavy edges and localized indentations, with flatness deviations reaching 0.3-1.2 mm / m, far exceeding the processing requirements for heat dissipation substrates. Therefore, a leveling process is essential for converting copper coils into substrates; only after leveling can subsequent processing proceed. Furthermore, when cutting the leveled copper coils, the substrate dimensions need to be adjusted according to the size of the heat-generating components to reduce material waste. Therefore, centralized processing equipment is urgently needed to address these issues. Summary of the Invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In this invention, a copper coil is hung on a hanging cylinder mechanism via a loading mechanism. The beginning of the copper coil then passes sequentially through a first rolling mechanism and a second rolling mechanism to flatten it before entering the cutting mechanism for cutting. Before cutting, based on the required lateral dimensions of the heat dissipation substrate to be cut, the side plate is removed, and a certain number of first cutting blades are installed on the sliding rod. The number of first cutting blades is the number of sections to be cut minus one. The spacing between the first cutting blades is the lateral dimension of the heat dissipation substrate. Then, the first and second cutting blades cut the steel ring via a lifting main frame. Thus, this invention achieves the effect of flattening the copper coil before cutting, with the cutting size adjustable according to requirements, offering advantages of high flexibility and high automation.

[0021] 2. In this invention, after adjusting the spacing of the first cutting blades, the bolts are passed through the first transverse grooves and screwed into the first threaded holes to fix the first cutting blades. Then, a flattening block is inserted between the transverse grooves of adjacent first cutting blades. The flattening block further flattens the steel coil during the cutting process, making it more flat. During cutting, the main frame is lowered by the first hydraulic cylinder, so that the first cutting blades cut the steel coil into segments. Then, the main frame is raised and the steel coil is advanced a certain distance, which is the longitudinal dimension of the heat dissipation substrate. After that, the first hydraulic cylinder lowers the main frame again, so that while the first cutting blades cut the steel coil into segments, the second cutting blades cut off the already cut portions, completing the cutting process of the heat dissipation substrate blank.

[0022] 3. In this invention, the steel coil is hung on the hanging rod of the hanging cylinder mechanism by the loading mechanism, and the rotation of the steel coil is controlled by the rotation of the first motor, thereby controlling its discharge speed; the second hydraulic cylinder causes the first rotating shaft to rotate through the connecting plate, so that the first contact roller on the first rotating frame abuts against the steel coil, preventing it from shaking during rotation and falling off the hanging rod.

[0023] 4. In this invention, the steel coil is hung on the hanging rod of the connecting seat in the loading mechanism by an external device. Then, the connecting seat is rotated so that the hanging rod with the steel coil is parallel to the guide rail. The moving trolley is driven to move to the bottom of the steel coil. Then, the third hydraulic cylinder rises so that the arc surface of the placement platform supports the steel coil. The platform moves outward to remove the steel coil from the hanging rod. The moving trolley is then driven to move to the side of the hanging rod of the hanging cylinder mechanism. The height of the steel coil is adjusted by the third hydraulic cylinder so that the core of the coil is aligned with the hanging rod. The moving trolley is driven to move towards the hanging rod until the steel coil is completely hung on the hanging rod. Then, the placement platform descends and separates from the steel coil, completing the loading process.

[0024] 5. In this invention, the opening of the steel coil passes over the second bonding roller of the first leveling mechanism, and is then introduced between the second and first leveling rollers. The extension end of the fourth hydraulic cylinder performs a telescopic movement, driving the connected second rotating frame to rotate. Since the second bonding roller is mounted on the second rotating frame, the rotation of the second rotating frame changes the angle of the second bonding roller. When the steel coil passes through the second bonding roller, the adjustment of the second bonding roller's angle forces it to bend in the opposite direction, effectively eliminating some of the internal stress generated during the rolling and coiling process. Because the internal stress distribution of the steel coil is uneven during production, the reverse bending redistributes these stresses, creating favorable conditions for subsequent leveling operations. The reverse-bent steel coil enters between the second and first leveling rollers. As the steel coil passes between them, the first and second leveling rollers apply pressure to the steel coil, causing it to undergo plastic deformation under pressure, thus achieving initial leveling. This process can reduce the undulations and unevenness on the surface of the steel coil, thereby improving the overall flatness of the steel coil to a certain extent.

[0025] 6. In this invention, the initially flattened steel coil then enters the second flattening mechanism between the third and fourth flattening rollers. The function of the fifth hydraulic cylinder is to adjust the gap height between the third and fourth flattening rollers. The piston rod of the fifth hydraulic cylinder extends and retracts, pushing or pulling the fourth flattening roller, thereby changing the distance between the two rollers. The operator can precisely adjust this gap height according to the thickness, material, and required flatness of the steel coil. When the steel coil passes between the third and fourth flattening rollers, the appropriate gap height and the rotation of the flattening rollers will cause further plastic deformation of the steel coil, further eliminating residual stress inside the steel coil, enabling the steel coil to achieve a higher flatness and meet the requirements of subsequent processing.

[0036] Example: A planar cutting and processing equipment for heat dissipation substrates, configured as follows Figure 1-8 As shown, including

[0037] The hanging cylinder mechanism 1 includes a platform 10, in which a hanging cylinder rod 12 controlled by a drive mechanism is provided. The hanging cylinder rod 12 is used to string steel coils and the feeding speed is controlled by the rotation speed of the hanging cylinder rod 12 controlled by the drive mechanism.

[0038] The loading mechanism 2 is located at the feeding end of the hanging cylinder mechanism 1; the loading mechanism 2 is used to transport the steel coil and hang it on the hanging cylinder rod 12;

[0039] The first rolling mechanism 3 is set at the discharge end of the hanging cylinder mechanism 1; the first rolling mechanism 3 is used to roll the steel coil to reduce the undulation and unevenness of the steel coil surface.

[0040] The second rolling mechanism 4 is located at the discharge end of the first rolling mechanism 3. The second rolling mechanism 4 is used to further improve the surface flatness of the steel coil.

[0041] The cutting mechanism 5 is located at the discharge end of the second rolling mechanism 4. The cutting mechanism 5 includes a main frame 104, with multiple sliding rods 106 below the main frame 104, and multiple first cutting blades 107 distributed on the sliding rods 106. The rear end of the main frame 104 is detachably connected to a second cutting blade 108. The cutting mechanism 5 changes the spacing of the first cutting blades 107 according to the cutting size requirements, cuts the flattened steel coil into segments through the first cutting blades 107, and cuts off the segments through the second cutting blades 108.

[0042] Preferably, such as Figure 2As shown, the cutting mechanism 5 includes a first worktable 101, a fixed beam 102 horizontally mounted on the first worktable 101, a first hydraulic cylinder 103 mounted on the fixed beam 102, the first hydraulic cylinder 103 passing through the fixed beam 102 and connected to the main frame 104, and a side plate 105 detachably connected to the side of the main frame 104; a sliding rod 106 is disposed between the main frame 104 and the side plate 105; the cutting direction of the second cutting blade 108 is perpendicular to the cutting direction of the first cutting blade 107; the rear end of the first cutting blade 107 is provided with a first threaded hole 109. The main frame 104 is provided with a first horizontal groove 110, which corresponds to the first threaded hole 109; the first cutting blade 107 is provided with a second horizontal groove 111 on both sides, and a pressing block 112 is provided between two adjacent first cutting blades 107, with both sides of the pressing block 112 cooperating with the second horizontal groove 111; the lower end face of the first cutting blade 107 is lower than the lower end face of the pressing block 112, and the difference is the thickness of the heat dissipation substrate to be cut; the lower end face of the first cutting blade 107 is flush with the lower end face of the second cutting blade 108. Before cutting, based on the required lateral dimensions of the heat dissipation substrate to be cut, remove the side plate 105 and install a certain number of first cutting blades 107 on the sliding rod 106. The number of first cutting blades 107 is the number of cuts to be made minus one. The spacing between the first cutting blades 107 is the lateral dimension of the heat dissipation substrate. Then, screw bolts through the first transverse groove 110 and into the first threaded hole 109 to fix the first cutting blades 107. Next, insert flat blocks 112 between the transverse grooves of adjacent first cutting blades 107. The flat blocks 112 make the steel coil easier to cut. During the cutting process, the steel coil is further flattened to make it more even. During the cutting, the main frame 104 is lowered by the first hydraulic cylinder 103, so that the first cutting blade 107 cuts the steel coil into segments. Then the main frame 104 is raised and the steel coil is advanced a certain distance, which is the longitudinal dimension of the heat dissipation substrate. After that, the first hydraulic cylinder 103 lowers the main frame 104 again, so that while the first cutting blade 107 cuts the steel coil into segments, the second cutting blade 108 cuts off the segments, completing the cutting process of the heat dissipation substrate blank.

[0043] Preferably, such as Figure 5As shown, the hanging cylinder mechanism 1 includes a first motor 11 disposed on the side of the platform 10, the output end of the first motor 11 passing through the platform 10 and connected to the hanging cylinder rod 12; a first rotating shaft 13 is rotatably connected to the platform 10, and a first rotating frame 14 located on the side of the hanging cylinder rod 12 is provided on the first rotating shaft 13, with a first contacting roller 15 at the outer end of the first rotating frame 14; a second hydraulic cylinder 16 is provided on the platform 10, and a connecting plate 17 is rotatably connected to the extended end of the second hydraulic cylinder 16, and the connecting plate 17 is fixedly connected to the first rotating shaft 13. The steel coil is hung on the hanging cylinder rod 12 of the hanging cylinder mechanism 1 by the loading mechanism 2, and the rotation of the first motor 11 controls the rotation of the steel coil, thereby controlling its discharge speed; the second hydraulic cylinder 16 causes the first rotating shaft 13 to rotate through the connecting plate 17, so that the first contacting roller 15 on the first rotating frame 14 abuts against the steel coil, preventing it from shaking and falling off the hanging cylinder rod 12 during rotation.

[0044] Preferably, such as Figure 6 As shown, the loading mechanism 2 includes a guide rail 20 disposed on the side of the hanging cylinder mechanism 1. A moving trolley 21 is mounted on the guide rail 20. A third hydraulic cylinder 22 is disposed inside the moving trolley 21. The output end of the third hydraulic cylinder 22 is connected to a placement platform 23 located above the moving trolley 21. The upper surface of the placement platform 23 is a concave arc-shaped surface. A mounting seat 24 is disposed at the end of the guide rail 20 away from the hanging cylinder mechanism 1. A connecting seat 25 is rotatably connected to the mounting seat 24. Multiple hanging rods 26 are fixedly connected to the side of the connecting seat 25. The steel coil is hung on the hanging rod 26 of the connecting seat 25 in the loading mechanism 2 by external equipment. Then, the connecting seat 25 is rotated so that the hanging rod 26 with the steel coil is parallel to the guide rail 20. The moving trolley 21 is driven to move to the bottom of the steel coil. Then, the third hydraulic cylinder 22 is raised so that the arc surface of the placement platform 23 supports the steel coil. The platform is then moved outward to remove the steel coil from the hanging rod 26. The moving trolley 21 is then driven to move to the side of the hanging rod 12 of the hanging mechanism 1. The height of the steel coil is adjusted by the third hydraulic cylinder 22 so that the core of the coil is aligned with the hanging rod 12. The moving trolley 21 is driven to move towards the hanging rod 12 until the steel coil is completely hung on the hanging rod 12. Then, the placement platform 23 is lowered and separated from the steel coil, completing the loading.

[0045] Preferably, such as Figure 7As shown, the first leveling mechanism 3 includes a second worktable 30, on which multiple second motors 31 are mounted. The output ends of the second motors 31 are connected to first leveling rollers 32 rotatably connected to the second worktable 30. Multiple second leveling rollers 33 are mounted on the second worktable 30 above the first leveling rollers 32, with gaps between the second leveling rollers 33 and the first leveling rollers 32. A second rotating shaft 34 is mounted on the side of the second worktable 30 facing the hanging cylinder mechanism 1. A second rotating frame 35 is rotatably connected to the second rotating shaft 34, and a second contacting roller 36 is mounted on the outer end of the second rotating frame 35. Fourth hydraulic cylinders 37 are symmetrically arranged above the second worktable 30, and the output ends of the fourth hydraulic cylinders 37 are fixedly connected to the second rotating frame 35. The steel coil's opening passes over the second bonding roller 36 of the first leveling mechanism 3, and is then introduced between the second leveling roller 33 and the first leveling roller 32. The extension of the fourth hydraulic cylinder 37 causes it to extend and retract, rotating the connected second rotating frame 35. Since the second bonding roller 36 is mounted on the second rotating frame 35, the rotation of the second rotating frame 35 changes the angle of the second bonding roller 36. As the steel coil passes over the second bonding roller 36, the angle adjustment forces it to bend in the opposite direction, effectively eliminating some of the internal stress generated during rolling and coiling. Because the internal stress distribution of the steel coil is uneven during production, the reverse bending redistributes this stress, creating favorable conditions for subsequent leveling operations. The reverse-bent steel coil enters between the second leveling roller 33 and the first leveling roller 32. As the steel coil passes between them, the first leveling roller 32 and the second leveling roller 33 apply pressure, causing the steel coil to undergo plastic deformation under pressure, thus achieving initial leveling. This process can reduce the undulations and unevenness on the surface of the steel coil, thereby improving the overall flatness of the steel coil to a certain extent.

[0046] Preferably, such as Figure 8As shown, the second rolling mechanism 4 includes a third worktable 40, on which multiple third rolling rollers 41 are rotatably connected. Adjacent third rolling rollers 41 are connected by a synchronous belt to rotate synchronously and in the same direction. A third motor 42 is provided on the third worktable 40, and the output end of the third motor 42 is fixedly connected to the foremost third rolling roller 41. A fifth hydraulic cylinder 43 is symmetrically arranged above the third worktable 40. The extended end of the fifth hydraulic cylinder 43 faces downward and is connected to a weight 44. Multiple fourth rolling rollers 45 located above the third rolling rollers 41 are rotatably connected below the weight 44. Fixed shafts 46 are provided on the front and rear sides of the third worktable 40 and the front and rear sides of the weight 44, respectively. Multiple mounting brackets 47 are fixedly connected to the fixed shafts 46, and guide rollers 48 are rotatably connected to the mounting brackets 47. The steel coil, after initial rolling, then enters between the third rolling rollers 41 and the fourth rolling rollers 45 of the second rolling mechanism 4. The function of the fifth hydraulic cylinder 43 is to adjust the gap height between the third flattening roller 41 and the fourth flattening roller 45. The piston rod of the fifth hydraulic cylinder 43 extends and retracts, pushing or pulling the fourth flattening roller 45, thereby changing the distance between the two rollers. The operator can precisely adjust this gap height according to the thickness, material, and required flatness of the steel coil. When the steel coil passes between the third flattening roller 41 and the fourth flattening roller 45, the appropriate gap height and the rotation of the flattening rollers will cause further plastic deformation of the steel coil, further eliminating residual stress inside the steel coil, achieving a higher flatness, and meeting the requirements of subsequent processing.

[0047] Preferably, such as Figure 3 As shown, a T-slot 113 is horizontally provided on the rear side of the main frame 104; a T-block 114 is provided on the upper end of the second cutting blade 108, and the T-block 114 cooperates with the T-slot 113; a first through hole 115 is symmetrically provided at the rear end of the main frame 104, and the first through hole 115 communicates with the T-slot 113; a second threaded hole 116 is provided on the T-block 114, and the second threaded hole 116 corresponds to the first through hole 115. By cooperating the T-block 114 of the second cutting blade 108 with the T-slot 113 of the main frame 104, and screwing the bolt through the first through hole 115 into the second threaded hole 116, the second cutting blade 108 is connected and fixed to the main frame 104. The detachable design facilitates the replacement of the second cutting blade 108 after it wears out.

[0048] Preferably, such as Figure 3As shown, the side of the main frame 104 connected to the side plate 105 is provided with multiple third threaded holes 117; the end of the sliding rod 106 is provided with a fourth threaded hole 118; the side plate 105 is provided with multiple second through holes 119, which correspond to the third threaded holes 117 and the fourth threaded holes 118 respectively; the rear side of the side plate 105 is provided with multiple fifth threaded holes 120; the rear plate of the main frame 104 is provided with multiple third through holes 121, which correspond to the fifth threaded holes 120. After the first cutting blade 107 is installed on the sliding rod 106, the bolts are screwed through the second through holes 119 into the third threaded holes 117 or the fourth threaded holes 118, and through the third through holes 121 into the fifth threaded holes 120, so that the side plate 105 is connected and fixed to the main frame 104.

[0049] Working principle:

[0050] Loading: First, the copper coil is placed onto the hanging rod 26 of the loading mechanism 2 using external equipment. Then, the connecting seat 25 is rotated to align the hanging rod 26 with the guide rail 20. Next, the moving trolley 21 is driven to move below the copper coil, and the third hydraulic cylinder 22 rises, supporting the copper coil via the arc-shaped surface of the placement platform 23. The moving trolley 21 is then moved outward to remove the copper coil from the hanging rod 26. Subsequently, the moving trolley 21 is driven to move to the side of the hanging rod 12 of the hanging mechanism 1, and the height of the copper coil is adjusted by the third hydraulic cylinder 22 to align its core with the hanging rod 12. Finally, the moving trolley 21 is driven to move towards the hanging rod 12 until the copper coil is completely hung on it, the placement platform 23 descends and separates from the copper coil, completing the loading process. The first motor 11 of the hanging mechanism 1 rotates, controlling the rotation of the copper coil and thus its discharge speed. At the same time, the second hydraulic cylinder 16 causes the first rotating shaft 13 to rotate through the connecting plate 17, so that the first bonding roller 15 on the first rotating frame 14 comes into contact with the copper coil, preventing the copper coil from shaking and falling off the hanging rod 12 during rotation.

[0051] Rolling and shaping: After the copper coil exits, its opening first passes through the first rolling mechanism 3. The opening of the copper coil passes over the second bonding roller 36 of the first rolling mechanism 3, and is then introduced between the second rolling roller 33 and the first rolling roller 32. The extension end of the fourth hydraulic cylinder 37 extends and retracts, driving the second rotating frame 35 to rotate, thereby changing the angle of the second bonding roller 36. When the copper coil passes through the second bonding roller 36, it is forced to bend in the opposite direction, which can eliminate some of the internal stress generated during the rolling and coiling process, redistribute the stress, and create conditions for subsequent rolling. The copper coil that has undergone reverse bending enters between the second rolling roller 33 and the first rolling roller 32. These two rolling rollers apply pressure to the copper coil, causing it to undergo plastic deformation, achieving preliminary rolling and reducing surface undulations and unevenness. The copper coil that has undergone preliminary rolling enters between the third rolling roller 41 and the fourth rolling roller 45 of the second rolling mechanism 4. The fifth hydraulic cylinder 43 adjusts the gap height between the third leveling roller 41 and the fourth leveling roller 45. The operator can make precise adjustments according to the thickness, material, and required flatness of the copper coil. When the copper coil passes through these two leveling rollers, the appropriate gap height and the rotation of the leveling rollers cause the copper coil to undergo further plastic deformation, further eliminating internal residual stress and achieving a higher degree of flatness.

[0052] Cutting Process: Before cutting, preparations must be made according to the lateral dimensions of the heat dissipation substrate to be cut. First, remove the side plate 105, and then install a certain number of first cutting blades 107 on the sliding rod 106. The number of blades is the number of sections to be cut minus one, and the spacing between the first cutting blades 107 is the lateral dimension of the heat dissipation substrate. Next, screw the bolts through the first transverse groove 110 and into the first threaded hole 109 to fix the first cutting blades 107. Then, insert flattening blocks 112 between the transverse grooves of adjacent first cutting blades 107. The flattening blocks 112 can further flatten the copper coil during the cutting process, making it more flat. During cutting, the first hydraulic cylinder 103 lowers the main frame 104, and the first cutting blades 107 cut the copper coil into sections. Then the main frame 104 rises, advancing the copper coil forward a distance, which is the longitudinal dimension of the heat dissipation substrate. Then, the first hydraulic cylinder 103 lowers the main frame 104 again. While the first cutting blade 107 cuts the copper coil into segments, the second cutting blade 108 cuts off the segments that have already been cut, thus completing the cutting process of the heat sink substrate blank. The entire process is repeated cyclically, realizing automated processing from copper coil to heat sink substrate blank.
