Description
Technical field
The present invention relates to a kind of die-cutting process, especially a kind of with the mutually nested combination of different size product, the combined nesting die-cutting process that carries out multiple product processing successively.
Background technology
At present, along with the develop rapidly of digital products such as consumer electronics such as mobile phone, camera, adhesive tape, foam, screen cloth, PUR or the like and their certain combination, the demand of the part that the accurate cross cutting of process obtains is also increasing.The part of the accurate cross cutting of this process is commonly referred to cutting part.All to use the cutting part of some hollow types in the assembling of this electronic product and their parts; They sometimes adopt identical structure and material; The branch that size is just arranged on the appearance and size; For example: needs are shockproof with foam and glue isolation between mobile phone LCD and the shell, and also will use the cutting part that foam and dustproof screen cloth constituted of similar band glue on microphone, loudspeaker and the receiver.In addition, also need use similar double faced adhesive tape hollow cutting part in the LCD module.Cutting part required on the product of different model varies in size, and required cutting part also has and varies in size on the same model, but their material might be identical or part is identical.
The technology of this cutting part of processing all is the independent cross cutting of each product generally at present.Like this, because product is a hollow, middle raw material greatly have been wasted, and raw-material utilization rate is very low, and the cost of product is than higher.Every year, the so many consumer electronics products of worldwide production, the material of waste is very big.
Summary of the invention
The invention solves in the prior art wastes a large amount of raw-material shortcomings to each product cross cutting of setting type separately, and a kind of arrangement mode that adopts nested combination is provided, and improves the nested groups matched moulds cutting process of utilization rate of raw materials and production efficiency.
The technical solution adopted for the present invention to solve the technical problems is: a kind of nested groups matched moulds cutting process is characterized in that comprising the steps:
1, selects the product mix of ability nesting die-cutting: select a plurality of products that material therefor is identical or part is identical; The outer big product of nested combination will be selected the product of hollow type, and the product of nested combination internal layer will be selected non-overlapping product between the inward flange of its outward flange and adjacent outer product;
2, nested combination arrangement design: the hollow position of miscellaneous goods being put into big product; The inward flange zero lap of the outward flange of miscellaneous goods and adjacent big product; Be arranged in order into from outside to inside a combination from big to small; With the design of setting type of this unit of being combined as; Apart from serving as to jump distance, obtain the composing design of each product self with the jumping between each combination, make each product that varies in size in separately composing figure upper edge base stock page orientation or the jumping on the perpendicular direction apart from the jumping distance that all equals maximum product;
3, stationary knife mould, permutation and combination according to above-mentioned 2 and the corresponding cutting die of each product self composing design customization, the jumping distance in adjacent cutter chamber is arranged with product and is jumped apart from identical on each cutting die, and distance is jumped in the arrangement that equals maximum product;
4, according to machine cross cutting on the cutting die of design of above-mentioned 2 permutation and combination and above-mentioned 3 customizations; The product that makes is separated and packs; And the main waste discharge of preceding one product is compound last behind row film or diaphragm, the raw material as following one product descends one cross cutting again; The rest may be inferred, until the cross cutting of accomplishing all nested combination products.
Above-mentioned said material is identical or part is identical is meant that the raw material producer of two required uses of product is identical with model, and structure is identical; Part is identical to be meant that two the employed raw material of a certain part-structure of product producers are identical with model, and this part-structure is also identical.For example the structure of product () is respectively 5 layers from top to bottom: glue A, foam A, glue B, grenadine A, glue C.The structure of product (two) also is 5 layers, and the producer of 5 layer materials, model with put in order all identically with product (), be glue A, foam A, glue B, grenadine A, glue C, it is identical then to be called material.Material like fruit product (two) has only 3 layer materials identical with the material and the structure of product () with structure from top to bottom, for: glue A, foam A, glue B, it is identical just to be called part.
Above-mentioned said product is jumped distance, be meant on the same direction in same plane, adjacent two products center line between distance.
Distance is jumped in above-mentioned said cutter chamber, is meant all cutter chambeies are deployed in the same plane, and on same direction, the distance between the center line in adjacent two cutter chambeies.
When selecting nested product, without overlapped edge, prevent that product size that cross cutting comes out from not meeting the requirement of product design between the product.Nested large scale product and small-size product can be different shapes, also can be identical shapes; After the mutually nested composing that combines of the product that varies in size, small-size product has utilized the hollow waste discharge material of large scale product, has improved raw material availability, reduces cost, and raises the efficiency.
Employed cutting die can be that flat cutter also can be a dise knife.Can be according to the drawing requirement of each product and the technological requirement customization cutting die separately when producing.But on the cutting die arrangement mode in each cutter chamber will according to above-mentioned 2 described be that the permutation and combination design of unit is arranged with the group, jump apart from will be with the jumping of maximum product apart from arranging.The position of all around of different cutting dies on machine is adjustable, so that make the cross cutting of miscellaneous goods drop on the hollow waste material of big product, can go out qualified miscellaneous goods by cross cutting.
The order of cross cutting can be from inside to outside, also can be from outside to inside.
Introduce the process that goes up the machine cross cutting below.
The first step is earlier that raw material is compound according to structure and manufacturing technique requirent, comprises main material and auxiliary material (base stock or diaphragm).Main material is meant that the client finally uses all material on the product, for example various glue, foam, conducting foam, screen cloth, PUR, Copper Foil, aluminium foil, conducting strip or the like or their combination.Auxilliary material is meant in the manufacture process of product the auxiliary material that increase use for the convenience of making or transporting preservation, base stock for example, diaphragm or the like.
Peeling force: refer to power required when the unit width film becomes 90 degree or 180 degree to peel off from main material surface.According to varying in size of peeling force, can auxiliary material be divided into several grades, I for example, II, III, IV, six grades of V and VI.Below statement: " base stock I " expression is the base stock of I grade with peeling force between the corresponding film, diaphragm I represent and accordingly the peeling force between the film be the diaphragm of I grade, and the like.
Waste discharge with separate: waste discharge is meant on compound good strip after the cross cutting, with specific target material separating process from the strip.The principle of its utilization is the difference of the peeling force of target material (waste material or product) on different strips.With the base stock of the compound different peeling forces in simple double faced adhesive tape two sides is example: the material composite construction is from top to bottom: the base stock I of light peeling force, double faced adhesive tape, the base stock II of middle peeling force.At this moment, two-layer base stock begins to separate if get up and down respectively, and middle double faced adhesive tape can be walked along with the middle peeling force base stock II of bottom, separates with the light peeling force base stock I on upper strata.Suppose that cutting die is a rectangle, cutting die is cross cutting (cutter is cut from top to bottom) from the front, cuts the face of putting on two-layer (base stock I and glue), and the base stock II of peeling force does not cut and wears in the bottom.At this moment, if separate between the base stock II of peeling force in glue and the bottom, because intermediate rectangular has been cut and worn, during separation, the intermediate rectangular part can follow the middle peeling force base stock II of bottom to walk, the strip of band rectangular opening in the middle of remaining then forms.If the rectangle part on the base stock II of middle peeling force is a waste material, this is waste discharge, and the strip of the base stock I of band rectangular opening and glue can also continue processing in the middle of all the other, then is called main waste discharge; If during rectangle part to be exactly us final desired product, this process is called products of separated, and the base stock I and strips of glue of band rectangular openings in the middle of all the other if can not continue to process, then are called waste material.
General, if waste material has just directly been scrapped.And if product need supply follow-up use at the compound again one deck base stock of glue face with protection product or strip.Go up the base stock that the rectangle part surface also has the light peeling force of one deck for base stock II, peel off (peeling force between diaphragm and base stock is greater than the peeling force between base stock and the glue) again after the light pressure of available adhesive diaphragm and base stock, can be with this base stock waste discharge.And then compound one deck base stock protects convenient transportation, use.
Be the process that the machine cross cutting is gone up in example explanation with the product identical below with said structure, being example from inside to outside:
The first step: the inward flange of front, first road cross cutting miscellaneous goods, cut and wear base stock I and glue, separate along the adhesive surface between glue and the base stock II, stay mid portion on the base stock II as first waste discharge, stay part on the base stock I as the first main waste discharge;
Second step: behind the base stock II of the compound middle peeling force in the first main waste discharge bottom surface; Second road is the outward flange of front cross cutting miscellaneous goods again; Cut and wear base stock I and glue, along the adhesive surface between glue and the base stock II separate the small-size product and the second main waste discharge, the second main waste discharge was waited until for the 3rd step and is used; (diaphragm II representes that the peeling force between this diaphragm and the base stock I is the II grade with diaphragm II waste discharge with the light peeling force base stock I on the small-size product; And the peeling force between base stock I and the glue is the I grade, so base stock I is taken away by diaphragm II) after compound again base stock I protection, rewinding;
The 3rd step: the second main waste discharge that small-size product is outer, the base stock II of compound middle peeling force, the inward flange of front cross cutting large scale product, mid portion be as second waste discharge, and stay the 3rd main waste discharge; With the 3rd main waste discharge compound in behind the base stock II of peeling force, the outward flange of front cross cutting large scale product again, separate large scale product and the 4th main waste discharge, the 4th main waste discharge can be waited until the 4th and go on foot usefulness; With the light peeling force base stock I on the large scale product with adhesive diaphragm II waste discharge after, compoundly go up base stock I protection, rewinding;
The 4th step: repeated for the 3rd step;
And the like, accomplish cross cutting until all product mixes.
For the complicated product of intermediate structure, can each layer be decomposed into above-mentioned simple steps, compound again behind the cross cutting, process combination such as cross cutting is accomplished cross cutting again.
To be example from outside to inside, divided for four steps below:
The first step: the outward flange of front, first road cross cutting full-size product, separate along the adhesive surface between base stock II and the glue, periphery is stayed on the base stock I, waste discharge; The mid portion of staying on the base stock II is waited until the second step usefulness as the first main waste discharge;
Second step: the mid portion waste discharge is the first main waste discharge; Be a main material that piece is separate, be attached on the base stock II, and main material upper surface has base stock I; Remove the compound more complete base stock I of going up behind the piece base stock I above this with adhesive diaphragm II; Being base stock II below becoming, is base stock I above, and the centre is the independently strip formed of main material of a piece;
The 3rd step: at the inward flange of this strip back side cross cutting large scale product, cut and wear base stock II and main material, do not cut and wear base stock I; Two-layer base stock is separated; Stay base stock I and go up middle waste discharge as the second main waste discharge, the base stock II of peeling force during its another side has waited until for the 4th step and uses; Another part is base stock II, leaves a piece hollow master material on the base stock II, is the large scale product, again in surface recombination base stock I, rewinding; If be replaced with base stock not with holes to base stock II with holes, then again behind base stock III on the main material surface recombination, two-layer base stock is separated, product is stayed on the base stock III, and base stock II is stripped from, and compound again base stock I or base stock II obtain the large scale product, rewinding;
The 4th step: be compounded on the base stock II face with diaphragm III; Change strip base stock I into base stock III again; Separating protective film and base stock III change continuous base stock I or base stock II into after the base stock II waste discharge with the surface, and obtaining one side is base stock III; Another side is the main material of base stock I or base stock II, and main material is second a main waste discharge that piece is separate; According to above-mentioned second, third step, make the more product of internal layer through changing the bigger auxiliary material of peeling force, again up to making all nested products.
The nested number of plies of this scheme will receive the restriction of auxiliary material peeling force number of degrees.
Another kind of method from outside to inside:
The first step: the outward flange of front, first road cross cutting full-size product, separate along the adhesive surface between base stock II and the glue, periphery is stayed on the base stock I, waste discharge; The mid portion of staying on the base stock II is waited until the second step usefulness as the first main waste discharge;
Second step: the first main waste discharge is a main material that piece is separate; Be attached on the base stock II; And main material upper surface has base stock I, removes the compound more complete base stock I of going up behind the piece base stock I above this with adhesive diaphragm II, is base stock II below becoming; Be base stock I above, the centre is the independently strip formed of main material of a piece.
The 3rd step: at the inward flange of this strip front cross cutting large scale product, cut and wear base stock I and main material, do not cut and wear base stock II, two-layer base stock is separated, base stock I is stripped from, waste discharge; Be a main material that piece is separate on the base stock II, every block of main material is cut into inside and periphery, and inside upper surface is coated with base stock I, and the glue of periphery exposes out; At the compound base stock III of upper surface, separate base stock II and base stock III again, at this moment, staying on the base stock III is exactly the large scale product, in the little surface recombination base stock I or the base stock II of large scale product, rewinding; Staying on the base stock II is the second main waste discharge, waits until for the 4th step and uses;
The 4th step: be used as the first main waste discharge to the second main waste discharge, repetition second goes on foot, and is base stock II below obtaining, and is base stock I above, and the centre is the independently strip formed of main material of a piece;
The 5th step: repeated for the 3rd step, after the separation, staying on the base stock III is second waste discharge, and staying on the base stock II is the 3rd main waste discharge;
The 6th step: the first main waste discharge is used as in the 3rd main waste discharge, was repeated for the 4th step and the 5th step, up to making all nested products.
The method will not receive the restriction of auxiliary material peeling force grade progression.
As preferably, mutually nested combination cross cutting comprises two products at least, and the nested product of the minimum innermost layer of size can be non-hollow.
Consider a kind of special situation, when the size between the small-size product of large scale product and nested inside differs big, can a plurality of undersized products be placed on side by side the hollow position of large scale product simultaneously.When being placed into the hollow position of big product, a plurality of miscellaneous goods to guarantee zero lap between the small-size product, zero lap between miscellaneous goods and the big product.A plurality of small sizes that will be positioned at together individual large scale product hollow position this moment make up as a small-size product to be treated, and participates in follow-up composing design and stationary knife mould or the like.
As preferably; The inner small-size product of large scale product can be that identical product also can be a Different products, can arrange according to zero lap each other when identical product is arranged, when the inhomogeneity product is arranged; Except zero lap each other; Also need follow following principle: have a line parallel with the raw material direction of advance can two Different products be separated, so that can separate into separately independently product volume after accomplishing, rather than same volume contains two or above different product.
As preferably, above-mentioned steps can also be not simultaneously, different machine cross cutting.After the former roads of nested product cross cutting separates, reclaim behind main compound base stock of waste discharge material or the diaphragm, as the main material of next group product.The cross cutting of next group product needn't be produced on uniform machinery at once, can be arranged on the different machines according to actual needs, also can be arranged in the follow-up indefinite time.The product of arranging production also needs not to be design in advance and arranges well; As long as this product size can drop in this main waste discharge material; Principle when then following permutation and combination design for the first time; According to the first time permutation and combination jumping apart from nested permutation and combination and customize cutting die, this main waste discharge material promptly capable of using makes product.
The invention has the beneficial effects as follows: with existing be the visual field consider the to set type method of design with single product; Expanding to the product that all materials are identical with structure or part is identical is the visual field consider the to set type mode of design; Through will vary in size, the nonoverlapping number of products in edge is nested arrangement with the combination; Then through from inside to outside or order from outside to inside carry out cross cutting; Make the waste discharge of big product hollow space can be used as the raw material of miscellaneous goods, improve raw-material utilization rate, provide cost savings.

(3), the stationary knife mould, the permutation and combination according to above-mentioned 2 and the corresponding cutting die of each product self composing design customization, the cutter chamber in adjacent cutter chamber is jumped distance and is arranged with product and jump apart from identical on each cutting die, the product that equals maximum product is arranged and is jumped distance; Distance is jumped in described cutter chamber, is meant all cutter chambeies are deployed in the same plane, and on same direction, the distance between the center line in adjacent two cutter chambeies;
(4), according to machine cross cutting on the cutting die of design of above-mentioned 2 permutation and combination and above-mentioned 3 customizations; The product that makes is separated and packs; And with behind compound upward mould release membrance of the main waste discharge of preceding one product or the diaphragm, the raw material as following one product descends one cross cutting again; The rest may be inferred, until the cross cutting of accomplishing all nested combination products.
2. combined nesting die-cutting process according to claim 1 is characterized in that mutually nested combination cross cutting comprises two products that material is identical or part is identical at least, and the minimum nested product of inside dimension is hollow hollow or non-.
3. combined nesting die-cutting process according to claim 1 and 2 when it is characterized in that product gap between the small-size product of large scale product and nested inside is big, is placed on a plurality of undersized products the hollow position of large scale product simultaneously side by side.
4. combined nesting die-cutting process according to claim 3; It is characterized in that the inner small-size product of large scale product is with a product or a different product; When Different products is arranged; Follow following principle: have a line parallel can two Different products be separated, so that can be divided into two Different products volumes behind the cross cutting with the raw material direction of advance.
5. combined nesting die-cutting process according to claim 1 and 2 is characterized in that beginning the first road cross cutting from small-size product when product carries out cross cutting perhaps begins the first road cross cutting from the large scale product.
6. combined nesting die-cutting process according to claim 1 and 2; It is characterized in that the cross cutting order is outside successively from the inward flange of small-size product; Perhaps inside successively from the outward flange of large scale product; Perhaps begin cross cutting, carry out the cross cutting of large scale product and the cross cutting of small-size product after the separation more respectively from nested product centre position.
7. combined nesting die-cutting process according to claim 1; It is characterized in that between the different product it being that uniform machinery is accomplished simultaneously; Or temporarily accept after main waste discharge applied diaphragm or mould release membrance; When treating to design next time again or producing, the product arrangement jumping of permutation and combination gets final product apart from nested permutation and combination according to the first time.
