Machining process for solving waste discharging and material saving

Abstract

The invention provides a machining process for solving waste discharging and material saving. Punching and compounding are conducted through a single production line, finished products are output, the machining cost is reduced, and the machining precision is high. A roll material advances along a roller way by a jumping distance A, double-faced adhesive tape advances by a jumping distance B through an asynchronous machine after a lower release film of the double-faced adhesive tape is peeled off, the portions, with the first area shapes, of the double-faced adhesive tape are punched by knives A to be compounded on the upper surface layer of the roll material, A is larger than B, and then the roll material carries the double-faced adhesive tape with the first area shapes arranged at intervals to advance step by step. Upper release films on the portions, corresponding to the first area shapes, of the double-faced adhesive tape are rolled up through box sealing adhesive tape, then a complete PET film is compounded on the upper surface formed by the double-faced adhesive tape and the roll material, the portions, with the first area shapes, of the double-faced adhesive tape are punched again through knives B, then waste is discharged through the PET film, and the residual PET film connected to the upper surface of the double-faced adhesive tape is rolled up through the box sealing adhesive tape again. Then, injection-molded parts are attached to the double-faced adhesive tape in the set shape one by one, and finally a finished product is obtained through roll material rolling.

Description

technical field [0001] The invention relates to the technical field of material punching and compounding, in particular to a processing technology for solving waste discharge and material saving. Background technique [0002] In the existing coil material structure, the double-sided adhesive tape is glued on the coil material, and then the corresponding injection molded part is adhered to the double-sided adhesive tape. Since the injection molded part is small, it is not easy to stamp the corresponding double-sided adhesive tape directly on the surface of the coil material. Forming, so it is necessary to complete the corresponding double-sided adhesive form by compounding the double-sided adhesive on the coil material for multiple times. Since the double-sided adhesive needs to be completely compounded on the coil material, the cost of the entire process is relatively high. Contents of the invention [0003] In view of the above problems, the present invention provides a p...
