[0001] The invention relates to the technical field of metal surface wire drawing, in particular to a multifunctional wire brushing machine for a U-shaped aluminum frame with a robot linked to a turntable. Background Art

[0002] Straight brushing is a common form of metal surface drawing. It is a surface treatment method that uses a grinding device to form hair-like straight lines on the surface of the workpiece, thereby achieving a decorative effect.

[0003] In the display manufacturing industry, the U-shaped aluminum frame of the display is often treated with straight brush lines. As the size of the display and TV design continues to increase, the size of the U-shaped aluminum frame is also getting larger. Figure 1 As shown, the U-shaped aluminum frame 9 occupies a large area on the plane. This structural feature makes it suitable for brushing in a horizontal manner, and the horizontal brushing equipment for performing the corresponding brushing will occupy too much factory area. Therefore, in the prior art, in a factory of the same area, the number of brushing stations that can be implemented per unit area is quite limited.

[0004] Furthermore, the sizes of monitors of different brands and specifications are not uniform, and the U-shaped aluminum frames of monitors also have different sizes and specifications. Ordinary brushing equipment faces U-shaped aluminum frame workpieces of different sizes and specifications. Not only does it take a long time to load and unload materials, but it also takes a long time to replace fixtures and readjust the machine, resulting in low production efficiency.

[0005] Therefore, a new type of wire brushing equipment is urgently needed to more comprehensively support the wire brushing of U-shaped aluminum frame workpieces of different sizes. Summary of the invention
