Abstract
The utility model discloses a back gum composite structure. The composite structure comprises an outer protective film, an inner protective film, single back gum products and a bottom release film, wherein each single back gum product comprises a release film or a protective film and glue stuck to partial area of the back side of the release film or protective film; a plurality of single back gum products are attached to the bottom release film at intervals via glue; the inner protective film is attached to a plurality of release films or protective films; the adhesion between the glue and release films or protective films of the single back gum products is greater than that between the release films or protective films and the inner protective film; the inner protective film is cut off between the two rows of single back gum products along the non-glue area directions of the single back gum products; and the outer protective film is attached to the inner protective film. The composite structure has the beneficial effects that the stripping conditions of the original first protective film and the release films or protective films on the single back gum products are improved, so that when the inner protective film is stripped, the release film or protective film on the single back gum product is not taken away and the single back gum products do not fall off, thus simultaneously increasing the assembly yield and precision.
Description
Technical field
The utility model relates to the gluing product of cross cutting, particularly a kind of gum unitized construction.
Background technology
In recent years, the gum series products has been widely used in photoelectricity, communication, computer, automobile and other industries, and the different parts of arranging in pairs or groups have the functions such as shockproof, insulation, conduction, sticker.
General gum series products assembling mode can be divided into three kinds: one, carry out single product in conjunction with tool by hand and attach assembling; Two, client's parts attach the assembling of combination gum; Three, the combination gum attaches client's assembling parts.
The operating efficiency of the first assembling mode is low, the lower (error 〉=0.20mm) of assembly precision; The assembled fixture cost of the second assembling mode is higher, and mounting needs contraposition twice in the process, and efficient is lower, is only applicable to simultaneously the gum combined prod, and is pasted parts limited large (only flexible circuit board is applicable at present); The assembled fixture cost of the third assembling mode is lower, and efficient is higher, the higher (error≤0.10mm), be widely used at present of assembly precision.
But; attach in the assembling process of client's parts at the combination gum; because after the client requires easily to occur combination gum assembling product to gum product symmetry and rotation etc.; peel off the first protective membrane 1 easily with the upper release film of single gum product (or claim gum list product) or protective membrane 2 is taken away, release film or protective membrane 2 and the caducous problem of gum list product, as shown in Figure 1.
The utility model content
The purpose of this utility model is to provide a kind of gum unitized construction of being convenient to assemble; attach in the assembling process of client's parts to solve at the combination gum; when the first protective membrane is peeled off; easily with release film on the single gum product or protective membrane is taken away, release film or protective membrane and the caducous problem of gum list product, promote simultaneously yield and the precision of assembling.
For reaching this purpose, the utility model by the following technical solutions:
A kind of gum unitized construction; it comprises outer protective film; the internal layer protective membrane; gum list product and bottom release film; described gum list product comprise release film or protective membrane; reach the glue that stick together in release film or protective membrane posterior components zone; several gum list product are attached on the described bottom release film by described glue compartment of terrain; described internal layer protective membrane is attached on described several release films or the protective membrane; the glue of described gum list product and the clinging power of release film or protective membrane are greater than the clinging power of release film or protective membrane and internal layer protective membrane; described internal layer protective membrane cuts off between two row gum list product along gum list product adhesive-free area direction, and described outer protective film is attached on the internal layer protective membrane.
Preferably, described glue is adhesive tape or glue.
Preferably, described outer protective film is structure as a whole.
Preferably, described bottom release film is structure as a whole.
The beneficial effects of the utility model are: the glue by making gum list product and the clinging power of release film or protective membrane are greater than the clinging power of release film or protective membrane and internal layer protective membrane; and between two row gum list product, cut off the internal layer protective membrane along gum list product adhesive-free area direction; there is Jiao Qu to tear to the segmentation of adhesive-free area direction along single gum product again after the assembling and gets the internal layer protective membrane; thereby release film on internal layer protective membrane (being equivalent to former the first protective membrane) and the gum list product or the situation of peeling off of protective membrane have been improved; when the internal layer protective membrane is peeled off; release film or protective membrane are not pulled away on the single gum product; release film or protective membrane and gum list product do not come off; simultaneously; outside the internal layer protective membrane, stick on an outer protective film; being used for the assembling product process attaches and the location; thereby guaranteed the precision of assembling, promoted the yield of assembling.
