Second waste discharge film is bonded with light release film layer, then recycles the second waste discharge film, the second waste discharge film will be small
Light release film layer above hole is taken away, and the material of the second waste discharge film is horse traction adhesive tape.
As a further improvement of the foregoing solution, step S3 is based on a kind of optical cement waste discharge apparatus, the waste discharge apparatus packet
The upper nip rolls being oppositely arranged and lower nip rolls are included, the upper nip rolls and lower nip rolls are horizontally moveable, the upper nip rolls
Be used to press upper surface and the first waste discharge film of optical cement semi-finished product with lower nip rolls, the top of the upper nip rolls from a left side to
The right side is successively arranged waste discharge band dispensing shaft and waste discharge band collecting shaft；The specific steps of the step S3 are as follows:
Optical cement semi-finished product are arranged between upper nip rolls and lower nip rolls, and one end of the first waste discharge film is located at waste discharge band
On dispensing shaft, the other end is around upper nip rolls and is arranged on waste discharge band collecting shaft, and upper nip rolls and lower nip rolls are by first row
Useless film is punched foraminate side with OCA optical cement semi-finished product and is bonded, and rotary rowed scratch tape collecting shaft withdraws the first waste discharge film
And take away scrap rubber.
As a further improvement of the foregoing solution, the rewinding part of the first waste discharge film and OCA optical cement semi-finished product
The range of angulation is 45 °~180 °.
As a further improvement of the foregoing solution, the rewinding part of the first waste discharge film and OCA optical cement semi-finished product
Angulation is 90 °.
As a further improvement of the foregoing solution, the aperture in step S1 is circular hole.
As a further improvement of the foregoing solution, the diameter range of the circular hole is 1mm~8mm.
As a further improvement of the foregoing solution, the diameter range of the circular hole is 2mm~5mm.
The beneficial effects of the present invention are as follows: the present invention mainly passes through punching aperture, after the light release film layer on removal aperture,
First waste discharge film is bonded and then is taken away scrap rubber with the scrap rubber on the aperture of OCA optical cement semi-finished product, the first waste discharge film is
PVC material film compares general waste discharge film, and material is soft, closer with OCA layers be bonded, and will not cling light release film
Layer, therefore waste discharge effect is good, the scrap rubber on aperture can be cleaned out.
Detailed description of the invention

Specific embodiment
Specific embodiments of the present invention will be further explained below.It should be noted that for these implementations
The explanation of mode is used to help understand the present invention, but and does not constitute a limitation of the invention.In addition, invention described below
Technical characteristic involved in each embodiment can be combined with each other as long as they do not conflict with each other.
Embodiment 1 :-Fig. 4 referring to Fig.1, a kind of production technology of OCA optical cement, the OCA optical cement produced in the present embodiment
Semi-finished product 5 include light release film layer 7, OCA layer 8, weight release film layer 9 and the bottom membrane 10 set gradually from top to bottom, bottom membrane
10 for protecting OCA optical cement, and the production technology includes the following steps:
S1, OCA optical cement semi-finished product 5 are laid flat on the table, mold cutter 11 is punched from top to bottom, mold cutter 11
It is equipped with round cutter 12, light release film layer 7 and OCA layer 8 are completely cut through, 9 hemisection of weight release film layer, circular aperture is formed；
Light release film layer 7 above S2, removal aperture, concrete mode is to be bonded horse traction adhesive tape with light release film layer 7,
Horse traction adhesive tape clings the light release film layer 7 being completely severed, then recycle horse traction adhesive tape, horse traction adhesive tape by above aperture it is light from
Type film layer 7 is taken away；
S3, the first waste discharge film 3 is bonded with the scrap rubber on the aperture of OCA optical cement semi-finished product 5, first waste discharge is thin
Film 3 is the waste discharge film of PVC material, then withdraws the first waste discharge film 3 and takes away scrap rubber.
Referring to Fig. 1, step S3 is based on a kind of optical cement waste discharge apparatus, and the waste discharge apparatus includes the upper binder being oppositely arranged
Roller 4 and lower nip rolls 6, the upper nip rolls 4 and lower nip rolls 6 are horizontally moveable, and the upper nip rolls 4 and lower nip rolls 6 are used
It is from left to right successively set in the upper surface of pressing optical cement semi-finished product 5 and the first waste discharge film 3, the top of the upper nip rolls 4
There are waste discharge band dispensing shaft 1 and waste discharge band collecting shaft 2；
The concrete operation method of step S3 includes: that optical cement semi-finished product 5 are arranged between upper nip rolls 4 and lower nip rolls 6,
One end of first waste discharge film 3 is located on waste discharge band dispensing shaft 1, and the other end is around upper nip rolls 4 and is arranged in waste discharge band rewinding
On axis 2, upper nip rolls 4 and lower nip rolls 6 paste the first waste discharge film 3 and the scrap rubber on the aperture of OCA optical cement semi-finished product 5
It closes, rotary rowed scratch tape collecting shaft 2 withdraws the first waste discharge film 3 and takes away scrap rubber.Scrap rubber institute is exhausted in OCA optics adhesive process at present
Waste discharge film generally uses the adhesive tape of PET material, smaller with the viscosity of OCA layer 8, and hardness is big, if directly applying to small
The waste discharge in hole can be difficult to be bonded with aperture especially aperture edge, cause dumping unclean, the first waste discharge film 3 is compared general
Waste discharge film, using PVC material, material is soft, closer with being bonded for OCA layer 8, and the first waste discharge film 3 is easier to squeeze simultaneously
It is sufficiently bonded with aperture edge scrap rubber, and light release film layer 7 will not be clung, light release film layer 7 will not damaged, therefore arranged
Useless effect is good, the scrap rubber on aperture can be cleaned out.Currently, surface layer of the PVC film for all kinds of panels is packed, so again
Referred to as decorating film, attached glue film are applied to all conglomeraties, the waste discharge films for being used as optical cement such as building materials, packaging, medicine and are had
The advantages of having, is not yet found, and this point is in industry pioneering.
Further, the horizontal position of upper nip rolls 4 and lower nip rolls 6 is removable, nip rolls 4 and lower nip rolls 6 in movement
Horizontal position, make the first waste discharge film 3 rewinding part and 90 ° of 5 angulation of OCA optical cement semi-finished product, can increase
First waste discharge film 3 tears off angle when OCA optical cement semi-finished product 5, and such loading angle can make waste discharge effect more preferable.
Further, the diameter of the round cutter 12 is 3mm, meets the small of mobile phone screen camera shooting area of bed for being punched into
Hole.Referring to fig. 4, the inside of the blade 13 of the round cutter 12 towards the side of waste material be inclined edge, outside towards materials one
Side is straight sword, makes that compressional deformation will not be generated to optical cement product when punching, optical cement section is neat.
The above, only better embodiment of the invention, but the present invention is not limited to above-described embodiments, as long as
The technical effect of the present invention is achieved by any identical or similar means for it, all should belong to protection scope of the present invention.
