Description

Polarizer release film tearing mechanism

technical field

The utility model relates to a manufacturing device of a liquid crystal display panel, in particular to an operating device for peeling off a release film of a polarizing plate.

Background technique

A liquid crystal display panel is mainly composed of a glass substrate, a polarizer, a transparent electrode, an alignment film, a liquid crystal film, and a color filter. The polarizer is attached to the glass substrate and only allows light of a single polarization direction to pass through. In order to expose the adhesive layer on one side of the polarizer, the release film on the polarizer must be removed from the polarizer before bonding the polarizer.

In the operation process of removing the release film, the polarizer is usually attracted and fixed on the suction table, and then a strip-shaped release tape is attached to the release film of the polarizer to remove the polarizer by lifting the release tape. Pull the release film away from the polarizer.

In recent years, with the increase in the size of liquid crystal displays, the number of peeling tapes required to remove the release film has also increased, and the cost of this has become non-negligible. At the same time, a large amount of waste will be generated, which is extremely unfriendly to the environment. .

Therefore, Japanese Patent Publication 2007-094044 discloses a release film peeling device, which mainly contacts the release film on the polarizer in a rolling contact operation mode through a sticky and rolling roller, so that the release film Film peel, which saves the use of peel tape. This release film peeling device, when the size of the polarizing plate to be peeled off is large, it must use a roller with a large enough outer diameter and drive it with a suitable driving structure to be able to peel off the release film, so it needs The setting space is huge and the speed is slow, and it is not easy to control.

Utility model content

Therefore, the main purpose of the present utility model is to provide a polarizing plate release film tearing mechanism, which has low cost and is easy to install and operate.

The polarizing plate release film tearing mechanism of the utility model includes a moving element, a rotating element and a pressing element for tearing off the release film on the polarizing plate.

The moving element can be displaced relative to the polarizing plate, the rotating element has a degree of freedom of rotation and is arranged on the moving element, and the outer surface of the rotating element has an adhesive part, which is used to stick the release film, and the pressing element is arranged on the moving element on and close to the rotating element, and the pressing element has a pressing part, and the pressing part can press and contact the rotating element.

Thus, through the displacement of the moving element, the adhesive part on the outer surface of the rotating element contacts the release film at the edge of the polarizing plate, and then the rotating element rolls into contact with the release film, so that the edge area of the release film can be detached The polarizer is attached to the adhesive part on the outer surface of the rotating element, and finally the pressing element is pressed against the rotating element whose surface is covered with a release film, and the release film is clamped, and then the displacement of the moving element can be peeled off. Type film, compared with the prior art, this mechanism at least has the effect of saving the peeling tape.

Detailed ways

In order to more clearly describe the features, purpose and effects of the present utility model, preferred embodiments will be listed below and illustrated with reference to the accompanying drawings.

Please refer to Figure 1 and Figure 2-1, the utility model is a polarizer release film tearing mechanism, which is used to tear off the release film 20 on the polarizer 10, and the polarizer 10 is set on the adsorption platform 30 Above, it includes a moving element 40, a rotating element 50 and a pressing element 60, wherein the moving element 40 has degrees of freedom of horizontal displacement and vertical displacement relative to the polarizing plate 10, and can be displaced relative to the polarizing plate 10. In practice, the The moving element 40 is realized by being arranged on two sliding rails (not shown in the figure) which are superimposed on each other and are respectively arranged horizontally and vertically.

The rotating element 50 has a degree of freedom of rotation and is arranged on the moving element 40, and the outer surface of the rotating element 50 has an adhesive portion 51, the adhesive portion 51 is an adhesive tape, and the adhesive portion 51 is used to stick the release film 20. In addition, The rotating element 50 can be arranged on the height adjusting rod 70, the height adjusting rod 70 is pivotally connected with the moving element 40, and a tension spring 71 is arranged between the height adjusting rod 70 and the moving element 40, and the moving element 40 is also provided with an adjusting stud 72 , the adjusting stud 72 can be telescopically pushed against the height adjusting rod 70 to rotate, and the extension spring 71 is stretched, so that the height adjusting rod 70 can swing up and down slightly to change the height of the rotating element 50 .

The pressing element 60 is arranged on the moving element 40 and is close to the rotating element 50. The pressing element 60 includes a cylinder body 61 and a telescopic piece 62. At the end, the telescoping member 62 can move relative to the cylinder body 61 , so that the pressing portion 63 can tightly contact the rotating element 50 .
