[0002] In the processing and production process of copper bar heat dissipation plate, the copper bar needs to be cut and processed, and after cutting the copper bar, the end face of the cutting part needs to be polished, the polishing of the cutting part can not only remove the burrs and avoid the sharp edges from damaging the equipment, the operator or other components, but also remove the uneven area that may be formed during cutting, so that the copper bar surface is smoother, thereby improving the heat dissipation efficiency.

[0003] In the existing copper bar polishing process, manual polishing, mechanical polishing and grinding wheel polishing are usually used, the manual polishing is not only low in efficiency and high in labor intensity, but also prone to uneven polishing, the mechanical polishing often puts the copper bar into a vibrating polisher, however, it is only suitable for large-scale mass production and processing, and is not suitable for large-size or special-shaped copper bars, and cannot accurately polish the cutting part of the copper bar, the grinding wheel polishing is mostly used for polishing the surface of the copper bar, which is not suitable for polishing the end face of the cutting part of the copper bar, and the copper bar is locally heated during polishing, affecting the quality of the copper bar, some numerical control polishing equipment or laser polishing equipment are also used, these equipment are expensive and inconvenient to use, therefore, a copper bar processing device that is simple to operate, suitable for promotion and capable of polishing the end face of the cutting part of the copper bar is urgently needed. SUMMARY

[0004] In order to overcome the deficiencies in the background art, the utility model discloses a copper bar processing device, the utility model not only can conveniently and efficiently and stably clamp the copper bar, but also can fully and efficiently polish the end face and upper and lower surfaces of the cutting part of the copper bar.

[0005] To achieve the above object, the utility model adopts the following technical scheme:

[0006] A copper busbar processing device includes a support plate and legs evenly distributed on the lower part of the support plate. One side of the upper surface of the support plate is provided with a guide rail arranged along the length direction of the support plate. A worktable is provided on the guide rail, which can reciprocate along the guide rail and is used to place the copper busbar. The worktable surface is provided with two clamping plates that can be adjusted synchronously in opposite directions and are used to clamp and limit the copper busbar. The other side of the upper surface of the support plate is provided with a grinding mechanism that cooperates with the reciprocating worktable. The grinding mechanism includes several first grinding components arranged at intervals along the moving direction of the worktable. Each first grinding component includes a first grinding roller arranged perpendicular to the support plate and capable of rotating along the moving direction of the worktable. The cutting end of the copper busbar protruding from the worktable abuts against the first grinding roller, and the cutting end of the copper busbar is ground as the worktable reciprocates.

[0007] Furthermore, the first grinding component also includes a "C"-shaped mounting bracket, which is vertically mounted on the support plate and its opening corresponds to the worktable. The first grinding roller is mounted inside the "C"-shaped rotatable mounting bracket.

[0008] Furthermore, the grinding mechanism also includes several second grinding components arranged at intervals along the moving direction of the worktable. Each second grinding component includes two mounting plates and a second grinding roller. The two mounting plates are perpendicular to the support plate and are arranged correspondingly to each other. The second grinding roller is installed between the two mounting plates and can rotate along the moving direction of the worktable. The upper surface of the second grinding roller is on the same plane as the worktable surface.

[0009] Furthermore, several first grinding components and several second grinding components are arranged coaxially and intersectingly along the length of the support plate.

[0010] Furthermore, the workbench surface is provided with a transverse slide groove along the length of the support plate. A bidirectional lead screw is rotatably installed in the transverse slide groove and is coaxially arranged with the transverse slide groove. The lower part of each of the two clamping plates is provided with a slider A that slides with the transverse slide groove. The slider A at the lower end of the two clamping plates is provided with a screw hole A that is threaded with both ends of the bidirectional lead screw. One end of the bidirectional lead screw passes through the transverse slide groove and has a handle A at its end.

[0011] Furthermore, each of the two clamping plates has a pressure plate at the end of its opposite face near the grinding mechanism for pressing and limiting the copper busbar. One end of the pressure plate is rotatably connected to the clamping plate via a torsion spring.

[0012] Furthermore, the workbench surface is equipped with a baffle that can slide and adjust along the width of the support plate and is used to limit the contact of the copper busbar.

[0013] Furthermore, the worktable surface is provided with a longitudinal slide groove in the middle along the width direction of the support plate. A screw rod coaxially arranged with the longitudinal slide groove is rotatably installed in the longitudinal slide groove. The lower part of the baffle is provided with a slider B that slides with the longitudinal slide groove. The slider B is provided with a screw hole B that is threaded with the screw rod. The end of the screw rod away from the grinding mechanism passes through the longitudinal slide groove and has a handle B at its end.

[0014] Furthermore, the lower part of the workbench is provided with two guide plates located on both sides of the guide rail. A traveling wheel that cooperates with the guide rail is rotatably installed between the two guide plates. The lower part of the workbench is provided with a servo motor for driving the traveling wheel to move along the guide rail.

[0015] Furthermore, both ends of the guide rail are equipped with limit plates for limiting and protecting the worktable, and the side of the limit plate facing the worktable is equipped with a limit switch for controlling the servo motor to switch between forward and reverse rotation.

[0016] Compared with the prior art, the beneficial effects of this utility model are: by setting clamping plates that can move synchronously in opposite directions or in opposite directions, the copper busbar can be effectively limited and clamped according to its different width, providing strong support for the subsequent stable grinding of the cut end face of the copper busbar.

[0017] By setting torsion springs and pressure plates, the copper busbars can be properly pressed and limited to prevent them from vibrating and jumping during the polishing process, thus ensuring stable polishing of the copper busbars.

[0018] By setting a movable baffle, one end of the copper busbar can be stopped and resisted, so that the grinding end face of the other end of the copper busbar can effectively resist the grinding mechanism, providing strong support for the full and efficient grinding of the copper busbar end face.

[0019] By cooperating with the first grinding component and the worktable, the copper busbar end face can be driven to reciprocate in contact with the first grinding roller, thus achieving efficient grinding of the cut end face of the copper busbar.

[0020] By cooperating with the second grinding component and the worktable, the lower surface of the copper busbar end can be driven by the worktable to reciprocate in contact with the second grinding roller, thus achieving efficient grinding of the upper or lower surface of the copper busbar cutting end.

[0021] By using the first and second grinding components that are set at intervals and alternating, the end face and upper and lower surfaces of the copper busbar can be ground intermittently when grinding the cut end of the copper busbar. This ensures that the cut end of the copper busbar is ground with high quality, while also preventing the copper busbar from generating high temperature in the grinding area, which would affect the quality of the copper busbar.

[0022] By setting servo motors, wheels, limit plates, and limit switches, not only can the worktable achieve convenient, efficient, and stable reciprocating drive, but it can also achieve precise and efficient reciprocating drive.

[0023] This invention utilizes the cooperation of a reciprocating worktable and a grinding mechanism to not only conveniently and efficiently clamp copper busbars stably, but also to fully and efficiently grind the end face and upper and lower surfaces of the cut parts of the copper busbars. This effectively prevents the copper busbars from shaking, jumping, or generating high temperatures during the grinding process, providing strong support for high-quality grinding of copper busbars.

[0033] The technical solution of this utility model will be described below with reference to the accompanying drawings of the embodiments of this utility model. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this utility model for the convenience of describing this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0034] Please refer to the instruction manual appendix. Figures 1-8 This utility model provides a technical solution:

[0035] Example 1: A copper busbar processing device includes a support plate 6 and support legs 4 evenly distributed on the lower part of the support plate 6. A guide rail 7 is provided on one side of the upper surface of the support plate 6 along the length direction of the support plate 6. A worktable 3 capable of reciprocating along the guide rail 7 is provided on the guide rail 7. Specifically, two guide plates 10 are provided on the lower part of the worktable 3, respectively located on both sides of the guide rail 7. A traveling wheel 22 cooperating with the guide rail 7 is rotatably installed between the two guide plates 10. A servo motor 21 is provided on the lower part of the worktable 3 for driving the traveling wheel 22 to move along the guide rail 7. The worktable 3 is driven to reciprocate by the forward and reverse rotation of the servo motor 21. The guide plates 10 can cooperate with the guide rail 7 during the movement of the worktable 3, thereby ensuring the horizontal stability of the movement of the worktable 3.

[0036] The workbench 3 has two clamping plates 2 that can be adjusted synchronously in opposite directions or in opposite directions and are used to clamp and limit the copper busbars. Specifically, the workbench 3 has a transverse slide groove 11 that is arranged along the length of the support plate 6. A double-acting screw 12 that is coaxially arranged with the transverse slide groove 11 is rotatably installed in the transverse slide groove 11. The two ends of the double-acting screw 12 are rotatably connected to the inner walls of the two ends of the transverse slide groove 11. The lower part of the two clamping plates 2 is provided with a slider A17 that slides with the transverse slide groove 11. The slider A17 at the lower end of the two clamping plates 2 is provided with a screw hole A18 that is threaded with the two ends of the double-acting screw 12. One end of the double-acting screw 12 passes through the transverse slide groove 11 and has a handle A13 at its end.

[0037] On the other side of the upper surface of the support plate 6, there is a polishing mechanism 1 that cooperates with the reciprocating worktable 3 and polishes one end of the copper busbar protruding from the worktable 3. Specifically, the polishing mechanism 1 includes several first polishing parts 23. The first polishing parts 23 include a "C"-shaped mounting bracket 27 and a first polishing roller 28. The "C"-shaped mounting bracket 27 is vertically set on the support plate 6 and its opening is set corresponding to the worktable 3. The first polishing roller 28 is installed in the "C"-shaped mounting bracket 27 and can rotate along the moving direction of the worktable 3. The first polishing roller 28, which is perpendicular to the support plate 6, can effectively polish the end face of the copper busbar cutting end.

[0038] When grinding the cut part of the copper busbar, the horizontal copper busbar is first placed on the worktable 3, with the cut end of the copper busbar facing the grinding mechanism 1 and protruding from the worktable 3. Since the distance between the worktable 3 and the grinding mechanism 1 is fixed, the operator can adjust the position of the copper busbar so that the end face of the cut end of the copper busbar just touches the first grinding roller 28 in the first grinding component 23. Then, the rotating handle A13 drives the bidirectional lead screw 12 to rotate, and the bidirectional lead screw 12 drives the two clamping plates 2 to move towards each other to achieve clamping and limiting of the copper busbar. After the copper busbar is clamped and fixed, the operator only needs to start the servo motor 21, and use the reciprocating rotation of the servo motor 21 to drive the worktable 3 to move back and forth. As the worktable 3 moves back and forth, the end face of the cut end of the copper busbar repeatedly touches and grinds with the first grinding roller 28 in multiple first grinding components 23, realizing the intermittent grinding processing of the end face of the cut end of the copper busbar. While ensuring the grinding effect, it effectively avoids the generation of high temperature in the grinding part of the copper busbar.

[0039] In the second embodiment, during the grinding process of the end face of the copper busbar cutting part, the burrs on the upper and lower edges of the end face of the copper busbar cutting part will shift to the upper and lower surfaces of the copper busbar. In order to achieve the grinding treatment of the burrs on the upper and lower surfaces of the copper busbar cutting end, the grinding mechanism 1 also includes several second grinding components 24 arranged at intervals along the moving direction of the worktable 3. The second grinding component 24 includes two mounting plates 29 and a second grinding roller 30. The two mounting plates 29 are perpendicular to the support plate 6 and are arranged corresponding to each other. The second grinding roller 30 is installed between the two mounting plates 29 and can rotate along the moving direction of the worktable 3. The upper surface of the second grinding roller 30 is on the same plane as the table surface of the worktable 3, which allows the lower surface of the copper busbar cutting end to effectively contact and grind with the second grinding roller 30. The several first grinding components 23 and the several second grinding components 24 are arranged coaxially and crosswise in the length direction of the support plate 6.

[0040] When cutting the copper busbar end, the first grinding component 23 grinds the cut end face of the copper busbar, and then the second grinding roller 30 in the second grinding component 24 contacts the lower surface of the cut end of the copper busbar. As the worktable 3 moves back and forth, the burrs on the lower surface of the cut end of the copper busbar are ground. When it is necessary to grind the burrs on the upper surface of the cut end of the copper busbar, it is only necessary to flip the copper busbar and perform secondary grinding.

[0041] In Example 3, when polishing the copper busbar, the copper busbar is prone to vibration due to the contact between the copper busbar and the polishing mechanism 1. In severe cases, it may even jump out between the two clamping plates 2, affecting the polishing quality. In order to ensure the stable clamping of the copper busbar, each of the two clamping plates 2 is provided with a pressure plate 15 for pressing and limiting the copper busbar at the end of its opposite face near the polishing mechanism 1. One end of the pressure plate 15 is rotatably connected to the clamping plate 2 through a torsion spring 16. The torsion of the torsion spring 16 can be used to press the copper busbar with the pressure plate 15 at all times, thus avoiding the vibration of the copper busbar.

[0042] In Example 4, when grinding the cut end of the copper busbar, it is necessary to ensure that the cut end of the copper busbar is in full contact with the grinding mechanism 1. However, as the copper busbar and the grinding mechanism 1 reciprocate to grind, although the two clamping plates 2 can clamp the copper busbar left and right, they cannot limit the copper busbar front and back. If the copper busbar moves backward under force, it will affect the subsequent grinding quality. In order to effectively limit and fix the copper busbar in the front and back direction, the workbench 3 is provided with a baffle 5 that can slide and adjust along the width direction of the support plate 6 and is used to limit the copper busbar. Specifically, the workbench 3 is provided with a longitudinal slide groove 8 in the middle of the workbench 3 along the width direction of the support plate 6. A screw 9 is rotatably installed in the longitudinal slide groove 8 and is coaxially arranged with the longitudinal slide groove 8. The baffle 5 is provided with a slider B20 that slides with the longitudinal slide groove 8. The slider B20 is provided with a screw hole B19 that is threaded with the screw 9. The end of the screw 9 away from the grinding mechanism 1 passes through the longitudinal slide groove 8 and has a handle B14 at its end.

[0043] In order to avoid the mutual interference between the longitudinal slide 8 and the transverse slide 11 affecting the movement adjustment of the baffle 5, the transverse slide 11 can be set at the end of the worktable 3 away from the grinding mechanism 1. The overlapping part of the bidirectional lead screw 12 in the transverse slide 11 and the screw 9 in the longitudinal slide 8 is located at the end away from the grinding mechanism 1, thereby reducing the interference to the movement of the baffle 5.

[0044] Or as per the instruction manual Figure 1 and 2 As shown, a partition is provided at the overlapping part of the transverse slide groove 11 and the longitudinal slide groove 8. The width of the partition is adapted to the length of the unthreaded section of the bidirectional lead screw 12. The groove depth of the transverse slide groove 11 is greater than the groove depth of the longitudinal slide groove 8. The longitudinal slide groove 8 passes through the partition at the middle of the transverse slide groove 11 and is not connected to the transverse slide groove 11. This allows the baffle 5 to move and adjust smoothly along the longitudinal slide groove 8 without conflicting with the transverse slide groove 11 and the bidirectional lead screw 12 inside.

[0045] In Example 5, to ensure that the worktable 3 can move safely back and forth on the guide rail 7, both ends of the guide rail 7 are provided with limit plates 25 for limiting and protecting the worktable 3. The limit plates 25 can effectively prevent the worktable 3 from derailing accidentally. In order to avoid the collision between the worktable 3 and the limit plates 25 and to improve the accuracy of the reciprocating movement of the worktable 3, the side of the limit plates 25 facing the worktable 3 is provided with a limit switch 26 for controlling the servo motor 21 to switch between forward and reverse rotation.
