Spring plate open window waste-fetching technological process

Abstract

The present invention provides a technological method for windowing the shrapnel and discharging the wasted piece. The wasted shrapnel of internal frame is sucked by shrapnel, doctor blade and air suction gathering system. The shrapnel is installed with a 45 DEG direction in the surface of mold-cut product material. The doctor blade which is inclined is installed in front of the planar surface of mold-cut product material and shrapnel. The tip of doctor blade is positioned adjacently with the planar surface of mold-cut product material. An air suction port of air suction gathering system is positioned above the planar surface of mold-cut product material. The process of planar moving of mold-cut product material comprises the following steps: a first step, springing the side of inner frame of product with the shrapnel which forms 45 DEG to the surface of mold-cut product; a second step, shaving the inner frame wasted piece which has one sprung side off the surface of mold-cut product material; and a third step, sucking the wasted piece which is shaved from the surface of mold-cut product material with the air suction gathering system. The method of the invention increases the efficiency and saves labor cost. The on-line wasted piece discharging can be realized and the subsequent packaging trimming personnel is not required. Real-time on-line wasted piece discharging is realized on the machine and the phenomenon of adhesion does not exist. The finished product rate is up to 95% and is increased for 10% compared with the prior art.

Description

technical field [0001] The invention belongs to a processing method for die-cut products, in particular to an improved method for removing waste from die-cut products with inner and outer frames. Background technique [0002] In recent years, with the gradual popularization of mobile phones and handheld computers, the electronic communication equipment manufacturing industry has developed rapidly, which has driven the rapid development of the die-cutting industry. Especially for the electronic die-cutting products of the mobile phone industry, under the high standard requirements of the mobile phone manufacturing industry, the original simple die-cutting of the outer frame die-cutting product material has gradually developed to the inner and outer frame sleeve die-cutting. The inner and outer frame sleeve cutting products refer to products that are combined with double-sided adhesive tape to die-cut the outer frame and inner frame according to the different needs of customer...

Problems solved by technology

[0006] Second, the post-process tool piercing and waste discharge lead to product adhesion, and the scrap rate increases by 15%.

The inner and outer frame rubber of the product is seriously drawn, and after the drawing breaks, it rebounds to the surface of the product to form dirt and cause the product to be scrapped;
