Description

Technical Field

[0001] This utility model relates to the field of copper busbar heat sink technology, and in particular to a surface treatment device for processing copper busbar heat sinks. Background Technology

[0002] As a key component in power equipment, new energy batteries, and electronic devices, the surface treatment quality of copper busbar heat sinks directly affects their conductivity, heat dissipation efficiency, and long-term reliability. Traditional copper busbar surface polishing mainly relies on belt sanders or grinding wheels to remove oxide layers and burrs through hard grinding. However, this method has the following technical drawbacks:

[0003] 1. The rigid contact between the abrasive belt / wheel can easily cause hard scratches on the surface of the copper busbar, especially for high-purity soft copper materials, which may cause micro-cracks and reduce fatigue life;

[0004] 2. Existing belt / wheel grinding equipment can only grind copper busbar heat sinks with planar structures. When the surface of the copper busbar heat sink is irregular, especially when the surface is designed with heat dissipation fins, the existing grinding equipment cannot grind and polish the surface, nor can it grind and polish the narrow gaps.

[0005] 3. Existing grinding equipment can often only grind and polish one side of the copper busbar heat sink. During the grinding and polishing process, the copper busbar heat sink needs to be flipped over, which seriously affects the polishing efficiency of the copper busbar heat sink.

[0006] Therefore, there is an urgent need for a surface treatment device for processing copper busbar heat sinks that can overcome the above-mentioned shortcomings. Utility Model Content

[0007] In order to overcome the shortcomings of the prior art, this utility model discloses a surface treatment device for processing copper busbar heat sinks. This utility model can simultaneously polish and grind the two sides of the copper busbar heat sink, and in particular, it can effectively grind copper busbar heat sinks with complex geometric structures.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A surface treatment device for processing copper busbar heat sinks includes a base. A clamping mechanism for vertically holding the copper busbar heat sink is provided on the upper part of the base. The clamping mechanism includes a vertical plate, support rods, and pressure rods. The vertical plate is vertically disposed on the upper part of the base. Support rods perpendicular to the upper end face of the vertical plate are provided at both ends of the upper end face. Pressure rods parallel to and adjustable in height are provided on the upper parts of the two support rods. A polishing mechanism for polishing the two sides of the vertically placed copper busbar heat sink is also provided on the upper part of the base. The polishing mechanism includes two sliding blocks located on both sides of the clamping mechanism and capable of moving synchronously towards or away from each other. Rotating plates that rotate around their own axes and are parallel to the copper busbar heat sink are rotatably mounted on the upper parts of the two sliding blocks. Brush bristles are provided on the opposite surfaces of the two rotating plates.

[0010] Furthermore, a movable rod that can be slidably adjusted along the axial direction of the support rod is embedded in the upper end of the support rod, and the upper end of the movable rod is connected to the pressure rod.

[0011] Furthermore, a spring is fitted on the movable rod between the upper end face of the support rod and the pressure rod, with the two ends of the spring being fixedly connected to the upper end face of the support rod and the pressure rod, respectively.

[0012] Furthermore, the upper surface of the base is provided with a horizontal sliding groove that is perpendicular to the upright plate. A bidirectional lead screw is rotatably installed in the horizontal sliding groove along the axial direction of the horizontal sliding groove. Two sliding blocks are installed in the horizontal sliding groove and are threadedly driven to both ends of the bidirectional lead screw. One end of the bidirectional lead screw passes through the horizontal sliding groove and has a rotating handle at its end.

[0013] Furthermore, each of the two sliding blocks has a mounting plate parallel to the upright plate on its upper part, and the two rotating plates are respectively rotatably mounted on the opposite surfaces of the two mounting plates. The upper part of the sliding block is also equipped with a motor for driving the rotating plates to rotate.

[0014] Furthermore, the upper surface of the base is provided with a longitudinal sliding groove that is perpendicular to the horizontal sliding groove and passes through the middle of the horizontal sliding groove. The lower part of the vertical plate is installed in the longitudinal sliding groove and can be slidably adjusted along the longitudinal sliding groove. The lower part of the vertical plate located in the longitudinal sliding groove is provided with a movable groove that is axially arranged along the longitudinal sliding groove and passes through the vertical plate. A two-way screw passes through the movable groove and is clearance-fitted with the movable groove.

[0015] Furthermore, a handle is provided on one side of the upright panel.

[0016] Compared with the prior art, the beneficial effects of this utility model are: by setting a clamping mechanism, the copper busbar heat sink can be vertically clamped and placed, which provides strong support for the subsequent synchronous grinding and polishing of the two sides of the copper busbar heat sink.

[0017] The movable rod and spring allow the pressure rod to automatically press down under the force of the spring, thereby cooperating with the upright plate to effectively clamp the copper busbar heat sink.

[0018] The distance between the two rotating plates can be adjusted by two sliding blocks that can move synchronously in opposite directions or in opposite directions. This not only meets the requirements for polishing copper busbar heat sinks of different thicknesses, but also provides convenience for the subsequent loading and unloading of copper busbar heat sinks.

[0019] By using a brush for polishing, not only can the hard scratches on the copper busbar heat sink be avoided during the polishing process of traditional sanding belts or grinding wheels, resulting in better surface polishing quality, but it can also be applied to the polishing of copper busbar heat sinks with complex geometries, such as polishing the gaps between the heat dissipation fins on the surface of the copper busbar heat sink.

[0020] By setting a longitudinal sliding groove, the clamping mechanism can be moved, thereby enabling the loading and unloading of copper busbar heat sinks without adjusting the distance between the two rotating plates. This not only ensures the polishing precision of the copper busbar heat sink surface but also greatly improves the polishing efficiency of the copper busbar heat sink.

[0021] This invention not only enables convenient, efficient, and stable vertical clamping of copper busbar heat sinks of different sizes and specifications, but also allows for simultaneous polishing and grinding of both sides of the copper busbar heat sink. In particular, it can effectively grind copper busbar heat sinks with complex geometric structures. This invention has a simple structure and is easy to operate, providing strong support for the efficient grinding of copper busbar heat sinks. Attached Figure Description

[0026] 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.

[0027] Please refer to the instruction manual appendix. Figure 1-3 This utility model provides a technical solution:

[0028] Example 1: A surface treatment device for processing copper busbar heat sinks includes a base 7. The upper part of the base 7 is provided with a clamping mechanism 5 for vertically clamping the copper busbar heat sink. Specifically, the clamping mechanism 5 includes a vertical plate 13, support rods 12 and pressure rods 8. The vertical plate 13 is vertically arranged on the upper part of the base 7. Both ends of the upper end face of the vertical plate 13 are provided with support rods 12 that are perpendicular to the upper end face of the vertical plate 13. The upper part of the two support rods 12 is provided with pressure rods 8 that are parallel to and correspond to the upper end face of the vertical plate 13 and can be adjusted in height.

[0029] In order to achieve elastic clamping and fixing of the upper and lower ends of the copper busbar heat sink by the pressure rod 8 and the upright plate 13, a movable rod 10 that can slide and adjust along the axial direction of the support rod 12 is embedded in the upper end of the support rod 12. The upper end of the movable rod 10 is connected to the pressure rod 8. A spring 9 is sleeved on the body of the movable rod 10 between the upper end face of the support rod 12 and the pressure rod 8. The two ends of the spring 9 are fixedly connected to the upper end face of the support rod 12 and the pressure rod 8, respectively. The elasticity of the spring 9 allows the pressure rod 8 to automatically press down under the force of the spring 9, thereby cooperating with the upright plate 13 to achieve effective vertical clamping of the copper busbar heat sink. The width of the upright plate 13 and the pressure rod 8 must be smaller than the thickness of the copper busbar heat sink.

[0030] The upper part of the base 7 is also provided with a polishing mechanism for polishing the two sides of the vertically placed copper busbar heat sink. Specifically, the polishing mechanism includes two sliding blocks 6 located on both sides of the clamping mechanism 5 and capable of moving synchronously towards or away from each other. The upper surface of the base 7 is provided with a horizontal sliding groove 16 that is perpendicular to the upright plate 13. A bidirectional screw 18 is rotatably installed in the horizontal sliding groove 16 and is arranged along the axial direction of the horizontal sliding groove 16. The two sliding blocks 6 are slidably installed in the horizontal sliding groove 16. The two ends of the bidirectional screw 18 are threaded through the two sliding blocks 6. The two sliding blocks 6 can be driven to move synchronously towards or away from each other through the bidirectional screw 18. One end of the bidirectional screw 18 passes through the horizontal sliding groove 16 and has a handle 17 at its end.

[0031] Each of the two sliding blocks 6 has a mounting plate 1 parallel to the upright plate 13 on its upper part. The two rotating plates 2 are respectively rotatably mounted on the opposite surfaces of the two mounting plates 1. Since the mounting plates 1 are parallel to the upright plate 13, the two rotating plates 2 are also parallel to the upright plate 13. When the clamping mechanism 5 clamps the copper busbar heat sink, the copper busbar heat sink will necessarily be parallel to the mounting plate 1. The upper part of the sliding block 6 is also provided with a motor 4 for driving the rotating plates 2 to rotate around their own axis. The opposite surfaces of the two rotating plates 2 are provided with bristles 3. The bristles 3 can be made of metal wire bristles, such as stainless steel wire or copper wire, or non-metallic bristles, such as nylon or carbon fiber, or composite material bristles, such as gradient bristles or conductive bristles. The appropriate bristle material can be selected according to actual needs.

[0032] When polishing the surface of the copper busbar heat sink, pull up the pressure rod 8 to place the copper busbar heat sink vertically on the upper part of the vertical plate 13. Then release the pressure rod 8 and use the elasticity of the spring 9 to drive the pressure rod 8 to descend. The pressure rod 8 and the vertical plate 13 are used to vertically clamp the copper busbar heat sink. The two sides of the copper busbar heat sink are located on both sides of the clamping mechanism 5. After the copper busbar heat sink is clamped and fixed, rotate the handle 17 to drive the two sliding blocks 6 to move synchronously in opposite directions using the double-acting screw 18. When the brush bristles 3 on the two rotating plates 2 come into contact with the surface of the copper busbar heat sink, start the motor 4 to drive the rotating plates 2 to rotate. The rotation of the rotating plates 2 drives the brush bristles 3 to polish the surface of the copper busbar heat sink. Adjust the distance between the two rotating plates 2 according to the actual polishing needs to meet the polishing requirements of the copper busbar heat sink. When polishing copper busbar heat sinks with complex geometric structures, especially those with heat dissipation fins on the surface, the brush bristles 3 can effectively polish the gaps between the heat dissipation fins.

[0033] In Example 2, during the loading and unloading process of the copper busbar heat sink, repeatedly moving the two rotating plates 2 for loading and unloading operations not only fails to ensure that the distance between the two rotating plates 2 remains constant during the polishing process of the copper busbar heat sink, but also seriously affects the polishing efficiency. Especially when polishing copper busbar heat sinks of the same batch and size one by one, maintaining a constant distance between the two rotating plates 2 can ensure that the polishing quality of the copper busbar heat sink remains consistent. In order to achieve the loading and unloading operation of the copper busbar heat sink without moving the two rotating plates 2, the upper surface of the base 7 is provided with a longitudinal sliding groove 15 that is perpendicular to the horizontal sliding groove 16 and penetrates the middle of the horizontal sliding groove 16, and the upright plate 13... The lower part is installed in the longitudinal sliding groove 15 and can slide and adjust along the longitudinal sliding groove 15. The lower part of the vertical plate 13 located in the longitudinal sliding groove 15 is provided with a movable groove 14 that is arranged axially along the longitudinal sliding groove 15 and passes through the vertical plate 13. The bidirectional lead screw 18 passes through the movable groove 14. During the movement of the vertical plate 13 along the longitudinal sliding groove 15, the movable groove 14 can be used to prevent the bidirectional lead screw 18 from affecting the sliding of the vertical plate 13. A handle 11 is provided on one side of the vertical plate 13. The operator can push the clamping mechanism 5 to slide along the longitudinal sliding groove 15 through the handle 11. When loading and unloading, the clamping mechanism 5 is pushed out to the outside of the two rotating plates 2. When grinding, the clamping mechanism 5 is pushed between the two rotating plates 2.
