Description

  The present invention relates to a protective film peeling / removing device, and more particularly, to a pressure plate type protective film peeling / removing device for peeling and removing a protective film of a polarizing plate of a liquid crystal panel.

  An embodiment of a typical structure of a conventional protective film peeling / removing apparatus is a configuration performed by a roller, and includes a platen having a sticky surface, and the platen extends along the surface of the protective film of the polarizing plate by an attached driving device. The protective film moves while rolling from one side to the other side, and the platen adheres to the protective film and winds up while peeling off the protective film from the polarizing plate.

However, the conventional protective film peeling and removal apparatus has the following problems when actually applied.
1. The platen sticks the film of one layer and sticks the protective film of the next polarizing plate because the adhesive property of the protective film attached before that is used as the adhesive surface. After the peeling and removing operation, the outer diameter gradually increases and cannot be used for a long time. In addition, the adhered film covers the majority of the area of the platen surface, making it difficult to peel from the platen, and there is a problem that it takes time. If this problem is solved by exchanging the platen, there is a problem that the cost of using parts increases.
2. Since the contact state between the platen and the protective film surface of the polarizing plate is linear, there is a drawback that the pressing area is small, the stability is insufficient, and the film is not peeled off reliably. In addition, the platen becomes a rounded curved surface, and as soon as the edge of the protective film is peeled off, along with the curved peeling route, the polarizing plate is also dragged by the peeled film and becomes easy to bend at the same time. Is easily deformed and broken, the defect rate is increased, and the quality of the manufacturing process is lowered.

  Therefore, it is the user's desire to develop a more ideal and practical original design for the problems that existed in the conventional film peeling and removal device structure. It is also the goal and direction to be done.

  In view of this, the inventor has many years of experience in the manufacture and development and design of related products, and after designing and evaluating the above goals in detail, the present invention with practicality was obtained.

  Subsequently, the pressure-sensitive adhesive tape pressing device 60 lowers the pressure-holding table 62, and the pressure-holding table 62 is folded back on the pressure-sensitive adhesive tape 40 on the upper surface of the pressure plate 30 (the front side 301 of the pressure plate 30 of the pressure-sensitive adhesive tape 40 to the winding roller 52. The adhesive tape 40 is fixed so that it does not move.

  Next, as shown in FIG. 6, the displacement driving device 20 is driven to reciprocate horizontally in the X1-X2 direction, and the pressure plate 30 reciprocates back and forth a predetermined number of times as indicated by an arrow L1. According to the operation mode, a shearing force alternately and repeatedly acts in the opposite direction several times between the edge portion of the protective film 71 and the surface of the polarizing plate 70, whereby the edge portion of the protective film 71 and the polarizing plate are applied. 70 Adhesive strength with the surface is reduced. For this reason, at the moment when the protective film 71 is peeled off as described later, it is avoided that the polarizing plate 70 is dragged upward by the protective film 71 and bent and deformed, and a high-quality film peeling and removing effect is obtained. can get.

  Next, as shown in FIG. 7, the pressure plate 30 is moved in the X2 direction by the displacement driving device 20. When the movement is started, the end of the protective film 71 is moved in the X2 direction together with the adhesive tape 40, and the protective film 71 is peeled from the polarizing plate 70 from the end portion. The peeled portion of the protective film 71 is moved in the X2 direction while being adhered to the pressure-sensitive adhesive tape 40 at the position of the pressing flat surface portion 31 of the pressure plate 30, and the protective film following the end of the protective film 71 as shown in FIG. 71 is peeled from the polarizing plate 70.

  When the protective film 71 is completely peeled from the polarizing plate 70, the part of the protective film 71 that is sticking to the pressure-sensitive adhesive tape 40 of the pressing flat surface portion 31 of the pressure plate 30 is peeled off by a manual operation or a pulling device, and the peeled protective film. 71 is separated from the adhesive tape 40.

  In this state, the adhesive force of the adhesive tape 40 in the portion located on the lower surface of the presser flat surface portion 31 of the pressure plate 30 is weakened, and the portion of the adhesive tape 40 in which the adhesive force is weakened is replaced with an unused portion.
