Description

Technical Field

[0001] The invention relates to the technical field of metal fittings processing for audio and video equipment, and in particular to a modularly designed metal mesh production device and an assembly method thereof. Background Art

[0002] During the manufacturing process of home audio and video equipment, a metal mesh is usually installed on the outer surface of the speaker installation area of ​​the bottom shell to prevent the speaker from being touched by foreign objects and maintain the overall aesthetic effect.

[0003] Most of the existing metal meshes are thin screen structures with uniform overall structure, which are cut from a whole uniform mesh plate. Although the manufacturing process is simple and convenient, the overall structural strength is low. The metal mesh is easily deformed when it is located at the corners of the audio and video equipment under external forces, and the anti-fall deformation effect is poor. Using thick uniform mesh plates as raw materials is prone to sound blocking problems, and the sound emitted by the speakers is dull, affecting the hearing effect.

[0004] For this purpose, a non-uniform metal mesh with more holes in the middle, fewer holes on the outside, and no holes on the edge was developed and installed in the speaker installation area. During use, this non-uniform metal mesh has more holes in the middle and has a good sound transmission effect, and fewer holes on the outside, which has both higher structural strength and better anti-fall and anti-deformation effects.

[0005] Due to the wide variety of audio and video equipment and different structural sizes, the structures of the non-uniform metals that need to be produced are different, and the various hole layouts are also different. The current metal mesh production equipment with a single product structure and uniform mesh cannot be applied. Replacing the mold is time-consuming and labor-intensive, affecting the production speed, and the upper and lower molds need to be precisely adjusted after replacement before they can be used. Otherwise, the stamped metal mesh products will have poor quality and low precision. Therefore, it is urgent to develop a metal mesh production equipment suitable for the above-mentioned different structural sizes and different hole layouts. Summary of the invention

The adjustment motor (64) drives the transmission belt (63) to rotate, driving each U-shaped mounting seat (5) and the punching die (3) thereon to move horizontally and pass below the punching machine (2) respectively; S300. When the identification sensor identifies the punching die (3) corresponding to the input metal mesh hole specification, the central control module controls the adjustment motor (64) to stop, so that the U-shaped mounting seat (5) and the corresponding punching die (3) stay directly below the punching machine (2); S400. The central control module controls the positioning electromagnet (7) to be energized to adsorb and position the U-shaped mounting seat (5) moved directly below the punching machine (2); S500. The central control module controls the working end (21) of the punching machine (2) to move downward and approach the upper die (31), and controls the positioning electromagnet (7) to be energized, so that the upper die (31) is fixedly connected to the working end (21) of the punching machine (2); S600. The winding motor of the plate strip conveying module drives the winding roller to move, driving the metal plate strip (8) to be conveyed to the middle groove of the anti-shape mounting seat at the working end (21), and the punching machine (2) drives the upper mold (31) to move downward and merge with the lower mold (32) to perform punching (81) of the set specifications of the metal plate strip (8).
