Description

Technical Field

[0001] The invention relates to a flat cutting processing device for a heat dissipation substrate, belonging to the technical field of processing equipment. Background Art

[0002] As the core carrier of the thermal management system of electronic equipment, the heat dissipation substrate undertakes the key function of quickly exporting the heat source of the chip. Copper has become the preferred material for high-end heat dissipation substrates such as 5G base stations and new energy vehicle electronic control modules because of its high thermal conductivity and cost advantages. Industrial-grade copper materials are usually stored and transported in coiled form. While ensuring transportation efficiency, this form inevitably introduces plastic deformation and residual stress. After uncoiling, the copper plate presents wavy edges and local depressions, and the flatness deviation reaches 0.3-1.2mm / m, which far exceeds the processing requirements of the heat dissipation substrate. Therefore, the leveling process is a necessary link for the conversion of copper coils to substrates, and subsequent processing can only be carried out after it is leveled. At the same time, when cutting the leveled copper coils, it is necessary to adjust the size of the substrate according to the size of the heating element to reduce the waste of raw materials.

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

[0020] 1. In the present invention, the copper coil is hung on the hanging drum mechanism through the loading mechanism, and then the opening of the copper coil is passed through the first flattening mechanism and the second flattening mechanism in sequence, so that the copper coil becomes flat, and then enters the cutting mechanism for cutting; before cutting, according to the transverse size 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, and the number is the number of copies to be cut minus one, and the spacing between the first cutting blades is the transverse size of the heat dissipation substrate, and then the first cutting blade and the second cutting blade are cut on the steel ring by lifting the main frame. As a result, the present invention realizes the effect of cutting the copper coil after it is flattened, and the cutting size can be adjusted according to the needs, which has the advantages of high flexibility and high automation.

[0021] 2. In the present invention, after adjusting the interval of the first cutting blades, the bolt is passed through the first transverse groove and screwed into the first threaded hole to fix the first cutting blade, and 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 to make it more flat; during cutting, the main frame is lowered by the first hydraulic cylinder, so that the first cutting blade cuts the steel coil into sections, and then the main frame is raised and the steel coil is advanced forward by 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 the first cutting blade cuts the steel coil into sections while the second cutting blade cuts off the already cut part, thereby completing the cutting process of the heat dissipation substrate blank.

[0022] 3. In the present invention, the steel coil is hung on the hanging rod of the hanging mechanism through 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 rotates the first rotating shaft through the connecting plate, so that the first bonding roller on the first rotating frame conflicts with the steel coil, preventing it from shaking during the rotation and falling off the hanging rod.

[0023] 4. In the present invention, the steel coil is hung on the hanging rod of the connecting seat in the loading mechanism through external equipment, and then the connecting seat is rotated so that the hanging rod with the steel coil is parallel to the guide rail, and the moving trolley is driven to move to the bottom of the steel coil, and then the third hydraulic cylinder is raised so that the arc surface of the placement table holds the steel coil, and then moves outward to remove the steel coil from the hanging rod, and then the moving trolley is driven to move to the side of the hanging rod of the hanging drum mechanism, and the height of the steel coil is adjusted by the third hydraulic cylinder so that the coil core is aligned with the hanging drum rod, and the moving trolley is driven to move toward the hanging drum rod until the steel coil is completely hung on the hanging drum rod, and then the placement table is lowered and separated from the steel coil to complete the loading.

[0024] 5. In the present invention, the beginning of the steel coil passes through the second laminating roller of the first flattening mechanism, and then is introduced between the second flattening roller and the first flattening roller, and the extended end of the fourth hydraulic cylinder is used to perform telescopic movement, driving the second rotating frame connected thereto to rotate. Since the second laminating roller is installed on the second rotating frame, the rotation of the second rotating frame will change the angle of the second laminating roller. When the steel coil passes through the second laminating roller, it will be forced to bend in the reverse direction due to the adjustment of the angle of the second laminating roller, thereby effectively eliminating part of the internal stress generated by the steel coil during rolling and curling. Because the internal stress of the steel coil is unevenly distributed during the production process, these stresses can be redistributed through reverse bending, creating favorable conditions for subsequent flattening operations. The steel coil that has undergone reverse bending enters between the second flattening roller and the first flattening roller. When the steel coil passes between them, the first flattening roller and the second flattening roller exert pressure on the steel coil, causing the steel coil to undergo plastic deformation under the pressure, thereby achieving preliminary flattening. This process can reduce the undulations and unevenness on the surface of the steel coil, and improve the overall flatness of the steel coil to a certain extent.

[0025] 6. In the present invention, the steel coil after preliminary flattening then enters between the third flattening roller and the fourth flattening roller of the second flattening mechanism. The function of the fifth hydraulic cylinder is to adjust the gap height between the third flattening roller and the fourth flattening roller. The piston rod of the fifth hydraulic cylinder is extended and retracted to push or pull the fourth flattening roller, thereby changing the distance between the two rollers. The operator can accurately adjust the gap height according to the thickness, material and required flatness requirements of the steel coil. When the steel coil passes between the third flattening roller and the fourth flattening roller, the appropriate gap height and the rotation of the flattening roller will cause the steel coil to further undergo plastic deformation, further eliminate the residual stress inside the steel coil, and make the steel coil reach a higher flatness to meet the subsequent processing requirements.

[0044] Preferably, if Figure 6 As shown, the loading mechanism 2 includes a guide rail 20 arranged at the side of the barrel hanging mechanism 1, a moving trolley 21 is arranged on the guide rail 20, a third hydraulic cylinder 22 is arranged in the moving trolley 21, and the output end of the third hydraulic cylinder 22 is connected to a placement table 23 located above the moving trolley 21, and the upper end surface of the placement table 23 is a concave arc surface. The end of the guide rail 20 away from the barrel hanging mechanism 1 is provided with a mounting seat 24, a connecting seat 25 is rotatably connected to the mounting seat 24, and a plurality of 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 through external equipment, and then the connecting seat 25 is rotated so that the hanging rod 26 with the steel coil is parallel to the guide rail 20, and the moving trolley 21 is driven to move to the bottom of the steel coil, and then the third hydraulic cylinder 22 is raised so that the arc surface of the placement table 23 holds the steel coil, and then moves outward to remove the steel coil from the hanging rod 26, and then the moving trolley 21 is driven to move to the side of the hanging rod 12 of the hanging drum mechanism 1, and the height of the steel coil is adjusted by the third hydraulic cylinder 22 so that its coil core is aligned with the hanging drum rod 12, and the moving trolley 21 is driven to move toward the hanging drum rod 12 until the steel coil is completely hung on the hanging drum rod 12, and the placement table 23 is lowered and separated from the steel coil, and the loading is completed.

The second workbench 30 is provided with a second rotating shaft 34 on the side facing the drum hanging mechanism 1, on which a second rotating frame 35 is rotatably connected, and a second laminating roller 36 is provided at the outer end of the second rotating frame 35; a fourth hydraulic cylinder 37 is symmetrically arranged above the second workbench 30, and the output end of the fourth hydraulic cylinder 37 is fixedly connected to the second rotating frame 35. The beginning of the steel coil passes through the second laminating roller 36 of the first flattening mechanism 3, and then is introduced between the second flattening roller 33 and the first flattening roller 32. The extended end of the fourth hydraulic cylinder 37 is used to perform telescopic movement, driving the second rotating frame 35 connected thereto to rotate.

Because the internal stress of the steel coil is unevenly distributed during the production process, these stresses can be redistributed through reverse bending, creating favorable conditions for the subsequent flattening operation. The steel coil that has undergone reverse bending enters between the second flattening roller 33 and the first flattening roller 32. When the steel coil passes between them, the first flattening roller 32 and the second flattening roller 33 exert pressure on the steel coil, causing the steel coil to undergo plastic deformation under the pressure, thereby achieving preliminary flattening. This process can reduce the undulations and unevenness on the surface of the steel coil, and improve the overall flatness of the steel coil to a certain extent.

The steel coil after preliminary flattening then enters between the third flattening roller 41 and the fourth flattening roller 45 of the second flattening 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 is extended and retracted to push or pull the fourth flattening roller 45, thereby changing the distance between the two rollers. The operator can accurately adjust the 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 the steel coil to further undergo plastic deformation, further eliminate the residual stress inside the steel coil, and make the steel coil reach a higher flatness to meet the subsequent processing requirements.

[0049] Working principle:

[0050] Loading: First, with the help of external equipment, place the copper coil on the hanging rod 26 of the loading mechanism 2. Then rotate the connecting seat 25 so that the hanging rod 26 with the copper coil is in the same direction as the guide rail 20. Then drive the moving trolley 21 to move it under the copper coil, and the third hydraulic cylinder 22 rises to hold the copper coil by the arc surface of the placement table 23. Then move the moving trolley 21 outward to remove the copper coil from the hanging rod 26. Subsequently, drive the moving trolley 21 to move it to the side of the hanging rod 12 of the hanging drum mechanism 1, and adjust the height of the copper coil by the third hydraulic cylinder 22 so that its coil core is aligned with the hanging drum rod 12. Finally, drive the moving trolley 21 to move toward the hanging drum rod 12 until the copper coil is completely hung on the hanging drum rod 12, and the placement table 23 descends and separates from the copper coil, completing the loading. The first motor 11 of the hanging drum mechanism 1 rotates to control the rotation of the copper coil, thereby controlling its discharge speed. At the same time, the second hydraulic cylinder 16 rotates the first rotating shaft 13 through the connecting plate 17, so that the first laminating roller 15 on the first rotating frame 14 contacts the copper coil, preventing the copper coil from shaking and falling from the hanging rod 12 during rotation.

[0051] Rolling and shaping: After the copper coil is discharged, its opening end first passes through the first rolling mechanism 3. The opening end of the copper coil passes through the second laminating roller 36 of the first rolling mechanism 3, and then is introduced between the second rolling roller 33 and the first rolling roller 32. The extended end of the fourth hydraulic cylinder 37 is extended and retracted, driving the second rotating frame 35 to rotate, thereby changing the angle of the second laminating roller 36. When the copper coil passes through the second laminating roller 36, it will be forced to bend in the opposite direction, which can eliminate part of the internal stress generated by the copper coil during the rolling and curling process, redistribute the stress, and create conditions for subsequent rolling. The copper coil that has been reversely bent enters between the second rolling roller 33 and the first rolling roller 32. These two rolling rollers apply pressure to the copper coil, causing the copper coil to undergo plastic deformation, achieving preliminary rolling and reducing surface undulations and unevenness. The copper coil that has been initially rolled 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 flattening roller 41 and the fourth flattening 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 the two flattening rollers, the appropriate gap height and the rotation of the flattening rollers cause the copper coil to further undergo plastic deformation, further eliminating the internal residual stress and achieving a higher flatness of the copper coil.

[0052] Cutting process: Before cutting, preparations should be made according to the transverse dimensions of the heat dissipation substrate to be cut. First, remove the side panel 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 pieces to be cut minus one, and the spacing between the first cutting blades 107 is the transverse dimension of the heat dissipation substrate. Then, screw the bolt through the first transverse groove 110 into the first threaded hole 109 to fix the first cutting blade 107. Then, insert the flattening block 112 between the transverse grooves of adjacent first cutting blades 107. The flattening block 112 can further flatten the copper coil during the cutting process to make it more flat. During cutting, the first hydraulic cylinder 103 lowers the main frame 104, and the first cutting blade 107 cuts the copper coil into sections. Then the main frame 104 rises and advances the copper coil forward a distance, which is the longitudinal dimension of the heat dissipation substrate. After that, the first hydraulic cylinder 103 lowers the main frame 104 again, and the first cutting blade 107 cuts the copper coil into segments while the second cutting blade 108 cuts off the already cut segments, and finally completes the cutting process of the heat dissipation substrate blank. The whole process is repeated to realize the automated processing from the copper coil to the heat dissipation substrate blank.
