Description

Technical Field

[0001] This utility model relates to copper busbar processing technology, and in particular to an automated grinding equipment for removing oxide layers and burrs from the surface of copper busbars, which is suitable for high-precision grinding processing of copper busbars used in power and electrical equipment. Background Technology

[0002] As a core conductive component in power systems and electrical equipment, the surface smoothness and finish of copper busbars directly affect their conductivity, heat dissipation efficiency, and assembly accuracy. Currently, the industry primarily uses manual and semi-automatic methods for copper busbar polishing, which have the following technical drawbacks:

[0003] Manual grinding is inefficient and has poor precision: It relies on operators to use handheld angle grinders, sandpaper and other tools to grind the upper and lower surfaces of the copper busbar one by one. This is not only labor-intensive, but also has poor stability in terms of manually controlled grinding force and displacement path. The grinding thickness deviation between the upper and lower surfaces of the copper busbar is large, and it is easy to have local omissions or over-grinding. It cannot meet the requirements of high-precision assembly for the flatness of the copper busbar surface.

[0004] Semi-automatic grinding suffers from poor synchronization and weak adaptability: Most existing semi-automatic equipment adopts the mode of "manual push feeding + fixed grinding mechanism". The feeding speed and the rotation speed of the grinding mechanism cannot be accurately synchronized, resulting in inconsistent grinding depth of the copper busbar along its length. In addition, the height of the grinding wheel is mostly adjusted by manual knob. For copper busbars of different thicknesses, the machine needs to be stopped to replace the appropriate fixture, which is time-consuming and results in poor equipment versatility.

[0005] Insufficient clamping stability leads to low finished product qualification rate: Most existing clamping mechanisms are planar clamping plate structures, lacking a positioning structure adapted to the cross-section of the copper busbar. During the copper busbar polishing process, the impact force of the high-speed rotating polishing wheel can easily cause lateral displacement, resulting in scratches and disordered polishing patterns on the surface, low finished product qualification rate, and increased rework costs.

[0006] In summary, existing technologies cannot simultaneously achieve efficiency, precision, versatility, and stability in copper busbar grinding. There is an urgent need for an automated device that can achieve "precise feeding, stable clamping, synchronous grinding, and multi-thickness adaptation" to solve the aforementioned technical pain points.
