Description
Technical field
The utility model discloses a kind of fixed film, and particularly a kind of metal clips fixes film.
Background technology
Metal clips is also known as METAL DOME, is indispensable parts in ultra-thin keyboard, mobile phone key, passes through gold
Feel when category shell fragment can realize line conduction and increase button, metal clips are generally bonded on fixed film by glue,
In order to assemble.In order to increase feel during metal clips pressing, and make pressing more accurate, people would generally be in fixed film
The upper shell fragment opening position that corresponds to sets a salient point, is referred to as Plunger in industry, extrudes metal clips by salient point during pressing
Top.
At present, the mode of production of salient point mainly has three kinds,（1）, directly generated using UV glue, i.e., pass through UV on fixed film
Glue mode for dispensing glue UV glue on the opening position point for needing to generate salient point, then carries out UV solidifications, so as to form salient point, Ci Zhongfang
Formula is limited by UV glue self attributes, and dot shape is spherical, easily abrasion, and bump height can not possibly be made high；
（2）, first correspond to bump location on fixed film with diel and pull out a convex closure, reverse side forms a pit, passed through
Point gum machine puts UV glue in pit, then is solidified by UV, forms salient point, this structure needs to use the point of point gum machine one by one
Enter UV glue, complex operation, and UV glue salient points easily wear；（3）, first a small salient point is punched on PC materials, then will be small
Salient point is bonded in PET by UV glue and fixed on film, is solidified by UV and is combined together the two, asked although thickness can be solved
Topic and service life problem, but its procedure of processing is cumbersome, high processing costs.
The content of the invention
Complex steps or the shortcomings that easily wear when being processed for Plunger of the prior art mentioned above, this reality
Film is fixed with a kind of metal clips of new offer, it uses special processing mode to form salient point, and its structure is complete with routine
Difference, can both realize simple in construction, can effectively ensure that service life again.
The utility model solves the technical scheme that its technical problem uses：A kind of metal clips fixes film, fixed film bag
Include fixed film main body, micro- adhesive-layer, salient point, shell fragment, base material and bonding glue-line, base material and fixed film master is bonded in by micro- adhesive-layer
On body, protruding upward in fixed film main body to be provided with convex closure, salient point is arranged in the convex closure below fixed film main body, and salient point passes through micro-
Adhesive-layer is bonded together with fixed film main body, and bonding glue-line is provided with below base material, is correspondingly offered on base material and bonding glue-line
Shell fragment installation position, shell fragment are set corresponding to shell fragment installation position, and shell fragment is bonded together by micro- adhesive-layer and fixed film main body.
The technical scheme that the utility model solves the use of its technical problem further comprises：
Correspond to shell fragment installation bit positions on described base material and bonding glue-line and offer air slot.
Described base material uses PET material.
The beneficial effects of the utility model are：The utility model forms salient point using special processing mode, its structure with
Conventional is entirely different, can both realize simple in construction, can effectively ensure that service life again.
The utility model is described further below in conjunction with the drawings and specific embodiments.
Brief description of the drawings
Fig. 1 is the utility model decomposing state structural representation.
In figure, 1- fixes film main body, the micro- adhesive-layers of 2-, 3- salient points, 4- shell fragments, 5- base materials, 6- bonding glue-lines, 7- shell fragments peace
Fill position, 8- air slots, 9- convex closures.
Embodiment
The present embodiment is the utility model preferred embodiment, and other all its principle and basic structure are identical with the present embodiment
Or it is approximate, within scope of protection of the utility model.
Metal clips in the utility model, which fixes film, mainly includes fixed film main body 1, micro- adhesive-layer 2, salient point 3, shell fragment
4th, base material 5 and bonding glue-line 6, in the present embodiment, base material 5 is made of PET material, and base material 5 is bonded in solid by micro- adhesive-layer 2
Determine in film main body 1, protruding upward in fixed film main body 1 to be provided with convex closure 9, salient point 3 is arranged on the convex closure 9 of the fixed lower section of film main body 1
Interior, salient point 3 is bonded together by micro- adhesive-layer 2 and fixed film main body 1, and the lower section of base material 5 is provided with bonding glue-line 6, can be by viscous
The utility model is bonded on conductive FPC or PCB by rubber alloy layer 6.In the present embodiment, correspondingly opened up on base material 5 and bonding glue-line 6
There is shell fragment installation position 7, shell fragment 4 is set corresponding to shell fragment installation position 7, and shell fragment 4 is bonded by micro- adhesive-layer 2 and fixed film main body 1
Together, in the present embodiment, air slot 8 is offered corresponding to the opening position of shell fragment installation position 7 on base material 5 and bonding glue-line 6, is used for
Gas caused by the deformation of shell fragment 4 is discharged, it is more smooth in order to press.
The processing method that above-mentioned metal clips fixes film mainly comprises the steps：
（1）, in PC or PET sheet（In the present embodiment, specific material can be selected according to the thickness of salient point or other requirements）
On according to the position of salient point 3 be punched U-typed groove, i.e., by U-typed punching cutter, be punched on PC or PET sheet according to the position of salient point 3
Go out multiple through holes, because shape of through holes is U-typed, so, after punching, it still can be stayed on PC or PET sheet；
（2）, on PC or PET sheet paste protection board, to prevent the salient point 3 after punching from dropping；
（3）, by paste protection board after PC or PET sheet carry out secondary punch, this time punching and using U-typed be punched
Knife, multiple through holes are punched into according to the position of salient point 3 on PC or PET sheet, this time U-typed punching cutter setting direction of punching and the
Setting direction during one-step punching on the contrary, then twice be punched two relative U-typed grooves, then will be punched on PC or PET sheet
Circular salient point 3, protection board only carried out one-step punching one by one, then it only has a U-typed groove above, does not fall out,
Circular salient point 3 after punching is bonded on protection board, is not also fallen out；
（4）, by being posted glue（I.e. micro- adhesive-layer 2）PC after punching or PET sheet another side are pasted with fixed film main body 1
Together；
（5）, punching press paste, punching press is carried out to the position of salient point 3 by stamping machine, during punching press, the U-typed groove on protection board
Position can be bent, and salient point 3 is pushed down into fixed film main body 1 in the squeezing action of drift, simultaneously because the extruding of salient point 3 is made
With forming convex closure 9 raised one by one in fixed film main body 1, salient point 3 is arranged in convex closure 9；
（6）, tear PC or PET sheet after protection board and punching press off, fixed film main body 1 is solidified, by salient point 3 with it is fixed
Film main body 1 is fixedly installed togather；
（7）, base material 5 is pasted onto in fixed film main body 1；
（8）, stick on base material 5 bonding glue-line 6；
（9）, load shell fragment 4 at the shell fragment installation position 7 on base material 5, that is, complete the processing of fixed film.
The utility model forms salient point using special processing mode, and its structure is entirely different with routine, can both realize
It is simple in construction, service life is can effectively ensure that again.
