Description

Technical Field

[0001] The utility model relates to the technical field of etching part coating, in particular to a metal loudspeaker etching part coating cutting device. Background Art

[0002] Metal speaker etching is a key technology in the field of electronic product manufacturing, playing a particularly important role in the audio components of devices such as smartphones and tablets. This technology uses physical and chemical effects to precisely process metal films. Through exposure and plate making, and after development, the protective film in specific areas is removed. In subsequent processing, the metal parts come into contact with the corrosive liquid and are etched away, thus forming the required microporous structure and geometric shape. Metal speaker etching parts are characterized by dustproof and beautiful appearance, high precision, and strong mass production capabilities. Their pore size can reach 0.1mm, fully meeting the microporous technology requirements of various types of speakers. In addition, with the continuous innovation of etching technology, such as the application of etching superior plate process, not only has environmental pollution been reduced, but also production costs have been reduced and processing efficiency has been improved, making metal speaker etching parts more and more widely used in consumer electronic products.

[0003] Etched part lamination technology involves coating the surface of a metal with a thin film after the metal etching process to enhance the product's wear resistance, corrosion resistance, and fatigue resistance. This technology is widely used in the aerospace, automotive, and integrated circuit manufacturing industries. The selection of the lamination material is crucial; it must possess excellent adhesion, stability, and corrosion resistance to ensure the long-term reliability of the etched parts in harsh environments. During the lamination process, advanced thin film deposition, photolithography, and etching techniques are often employed. By precisely controlling the thickness, uniformity, and pattern accuracy of the film, the precise replication and processing of the etched part's surface microstructure can be achieved. Furthermore, with the advancement of laser technology, laser cutting and etching techniques have also been applied to lamination processes to meet the demands of high-precision and high-efficiency processing. Etched part lamination technology not only improves product performance and quality but also promotes technological advancement and industrial upgrading in related industries.

[0004] Patent document CN214562941U discloses a precision etching metal part coating device, including a base, a workbench and a dust cover, the dust cover is fixedly installed on the upper surface of the base, and a first opening is opened on both sides of the dust cover. The workbench passes through the two first openings, and telescopic rods are fixedly installed at the four corners of the lower surface. The lower end of each telescopic rod is fixedly connected to the upper surface of the base, and the rod wall of each telescopic rod is movably sleeved with a spring, and the two ends of each spring are fixedly connected to the corresponding upper surface of the base and the lower surface of the workbench. A plurality of second openings are opened inside the workbench, and the interior of each second opening is rotatably connected to a roller through a first bearing. A motor is fixedly installed on the left side wall of the dust cover. The utility model can remove dust from the surface of the metal part to be coated, thereby improving the coating quality of the metal parts.

[0005] As in the prior art of the above-mentioned patent, after the etching workpiece is coated, the above-mentioned device uses a cutting knife to cut the film at both ends of the etching workpiece. The cutting method of the above-mentioned device is only a simple cutting by the cutting knife and the electric telescopic rod, but this cutting method has two disadvantages. Since the etched workpiece after coating is above the transmission belt, the transmission belt may have a small offset movement. The above-mentioned cutter does not limit and fix the etching workpiece before cutting, so during the cutting process, it may cause the etching workpiece below to slide. Secondly, since the film toughness of the etching workpiece coating is generally strong, the cutter only simply cuts up and down, which may cause the film around the etching workpiece to fail to be cut off at one time, which results in insufficient cutting, and the film body still remains around the etching workpiece, affecting its yield rate.
