Problems solved by technology

[0004] The present invention solves the disadvantage of wasting a large amount of raw materials by typesetting and die-cutting each product separately in the prior art, and provides a nested and combined die-cutting process that adopts a nested and combined arrangement to improve raw material utilization and production efficiency

Embodiment 1

[0065] Embodiment 1: Die-cutting method from inside to outside: Two products of the same material and different sizes are chosen as examples for illustration. The product is mainly double-sided glued foam 6 . First double-sided adhesive tape 5 is applied on both sides of the foam, the original backing paper 11 of the double-sided adhesive tape 5 is replaced, the upper layer of adhesive is coated with the outer backing paper I1, and the lower layer of adhesive is coated with the outer backing paper II7. If the existing separate die-cutting process is used, the large-size products 3 are arranged in a manner of jump distance 4 (see attached Figure 1-I ), the small size products 2 are arranged according to the jump distance 8 (see attached Figure 1-II ), so that the inner and outer materials of the two products are wasted. Switch to a new die-cutting process: first design the combined arrangement of nested products (see attached drawing 1-111 attached drawing 1-VI), there is no ...

Embodiment 2

[0072] Embodiment 2: Die-cutting from outside to inside: at this moment, the first die 14 and the second die 17 are respectively the inner edge die and the outer edge die of large-sized products; the third die 18 and the fourth die Die 19 is respectively the outer edge cutting die and the inner edge cutting die of small size products. The process of making large-sized products remains the same, but the first row of waste 21 is the first main waste. After removing the backing paper I1 on the upper surface, the backing paper I1 is combined, and the front is die-cut to cut through the backing paper I1 and the main material. Cut through the backing paper II7, and separate the backing paper I1 and the backing paper II7; Figure 9 ), the vertical line that cuts through the main material in the figure indicates the position of the die-cutting; then compound the backing paper III on the upper surface and separate it, and the main material outside the outer edge of the small-sized prod...

Embodiment 3

[0073] Embodiment 3: If the large and small size products are to be produced in time, the discontinuous backing paper I1 on the upper surface of the first main waste discharge after the large-size product is made is replaced with a continuous backing paper I and stored as the next small Raw materials for dimension products. When using this raw material to produce small-size products, arrange and design first to ensure that the jump distance of the small-size products is the same as that of the original large-size products.

Abstract

The invention relates to a combined nesting die-cutting process for nesting and combining products with different sizes with one another and processing a plurality of types of products in turn. The combined nesting die-cutting process overcomes the defect that layout die cutting is performed on each product singly and a large number of raw materials are wasted in the prior art. The combined nesting die-cutting process comprises the following steps of: 1, selecting a product combination capable of being nested for die cutting; 2, designing a nested combination arrangement; 3, customizing a cutting die; and 4, performing machine die cutting according to the arrangement combination design of the step 2 and the cutting die customized by the step 3. The combined nesting die-cutting process enlarges the existing method which uses a single product as a visual field to take a layout design into account in to a mode which uses all products with the same or partially same materials ad structures as the visual field to take the layout design into account; besides, the combined nesting die-cutting process ensues that discharged wastes of a hollow part of a big product can be used as a raw material of a small product so as to improve the utilization ratio of the raw materials and save the cost by nesting, combining and arranging a plurality of products with different sizes and non-overlapping edges together and then performing the die cutting in an order from inside to outside or from outside to inside.

Description

technical field [0001] The invention relates to a die-cutting process, in particular to a combined nested die-cutting process in which products of different sizes are nested and combined to sequentially process multiple products. Background technique [0002] At present, with the rapid development of consumer electronics such as mobile phones, cameras and other digital products, the demand for parts obtained through precision die-cutting is also increasing. bigger. Such precision die-cut parts are often referred to as die-cuts. Some hollow die-cut parts are used in the assembly of such electronic products and their parts. Sometimes they use the same structure and materials, but the dimensions are different. For example: mobile phone LCD display and casing Foam and glue need to be used to isolate and shockproof, and similar die-cut parts composed of glued foam and dustproof mesh are also used on the microphone, speaker and earpiece. In addition, similar double-sided adhesi...
