According to different application requirements, the OCA optical adhesive tape needs to be processed, namely, the optical adhesive tape is subjected to structural design, die cutting or splitting according to an actual application attaching process, and is cut into films (for example, optical films for mobile phone touch screens) suitable for actual product shapes and sizes.
In the OCA laminating application process, it is a more outstanding quality problem to glue from type membrane area, seriously influences the laminating yield of laminating factory, causes the loss of touch-control module material extravagant, consequently need tear the membrane and draw gluey inspection to it after OCA cross cutting processing is accomplished. The common inspection method is to judge whether the finished OCA optical cement is qualified or not by observing whether the phenomenon of adhesive tape pulling exists or not through manual film tearing. When the film is manually torn, the inspection fails due to factors such as the movement of the bottom of the optical cement, the inspection misjudgment rate is high, and the inspection efficiency is low.
SUMMERY OF THE UTILITY MODEL
The utility model provides a dyestripping draws gluey verifying attachment adopts vacuum adsorption platform and backing plate to adsorb OCA optical cement, prevents that OCA optical cement from removing and leading to the inspection erroneous judgement.
The utility model adopts the technical proposal that: a tear film adhesive pulling inspection device comprises a vacuum adsorption platform, wherein a base plate with a smooth surface is arranged on the adsorption surface of the vacuum adsorption platform, and a plurality of vent holes communicated with an air suction channel of the vacuum adsorption platform are formed in the base plate; the base plate is covered with a film layer, the film layer is provided with a hollow part, and the hollow part corresponds to the area of the base plate, which is provided with the vent holes; the edge of the hollow-out part is provided with a pasting layer, and the thin film layer is fixedly pasted on the base plate through the pasting layer.
Further, the vacuum adsorption platform is provided with a support column, and the base plate is connected with the vacuum adsorption platform through the support column.
Further, the hollow-out part is rectangular.
Further, the thin film layer is provided with a plurality of hollow parts with different sizes.
Further, the backing plate is a PC plate.
Further, the film layer is a PET film.
Further, the sticking layer is a single-sided adhesive tape.
The utility model has the advantages that:
the utility model discloses a vacuum adsorption platform communicates its suction channel with the air vent of backing plate to set up the thin layer on the backing plate, form the fretwork portion as the adsorption zone. Through the negative pressure effect of the face of OCA optical cement and backing plate contact, make OCA optical cement adsorbed the laminating on the backing plate, tear the effect that plays the restriction from the in-process fretwork portion of type membrane, OCA optical cement can not remove because of the effort of tearing and lead to the unevenness to appear taking gluey, avoids the phenomenon of taking gluey that artificial factor leads to, reduces the dyestripping and draws the erroneous judgement rate of gluing the inspection, improves the efficiency of software testing simultaneously.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings.
Example 1
Referring to fig. 1 to 3, a tear film and glue pulling inspection device comprises a vacuum adsorption platform 10, wherein a base plate 20 with a smooth surface is arranged on an adsorption surface of the vacuum adsorption platform 10, and the base plate 20 is provided with a plurality of vent holes 21 communicated with an air suction channel 11 of the vacuum adsorption platform 10. The vacuum adsorption platform 10 is provided with a support column 12, and the backing plate 20 is connected with the vacuum adsorption platform 10 through the support column 12. The backing plate 20 is covered with a thin film layer 30, the thin film layer 30 has a hollow portion 31, and the hollow portion 31 corresponds to an area of the backing plate 20 where the vent holes 21 are formed. An adhesive layer 40 is arranged at the edge of the hollow part 31, and the film layer 30 is fixedly adhered to the backing plate 20 through the adhesive layer 40.
