Description

Technical Field

[0001] The utility model relates to the field of re-sticking mechanisms, in particular to a re-sticking mechanism for warping a rolled polarizing film. Background Art

[0002] The roll-type polarizer is a material used for optical applications and has special optical properties. The roll-type polarizer can selectively transmit or block light according to the vibration direction of the light, and many of them will use a mounting machine to attach it to the display screen or glass surface. For example, the utility model patent with the authorization announcement number CN207133536U proposes a polarizer attachment mechanism, including: a substrate adsorption platform, a polarizer adsorption platform, an attachment roller, a first positioning bar, and a second positioning bar. The polarizer attachment mechanism is provided with a first positioning bar and a second positioning bar near the lower edge of the substrate adsorption platform, and the second positioning bar forms an L-shaped structure with the first positioning bar.

[0003] However, when using existing mounting machines, many of them roll the polarizer onto the glass surface at once, which leaves a large amount of bubbles. In addition, since the roll polarizer is in a rolled state for a long time, it is easy to warp after being attached to the glass surface. Therefore, it needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to provide a mechanism for re-sticking a rolled polarizer, which solves the problem that many existing mounting machines roll the polarizer onto the glass surface once during use, resulting in large residual bubbles. At the same time, it solves the problem that the rolled polarizer is easily warped after being attached to the glass surface because it is in a wound state for a long time.

[0006] Preferably, a ball is disposed on the top of the moving block, and the ball contacts the inner surface of the adjusting seat. The relative friction between the moving block and the adjusting seat can be reduced by disposing the ball.

[0007] Preferably, a striker is fixedly connected to the middle section of the column body of the connecting column, and the striker is made of stainless steel. Through the arrangement of the striker, a thrust can be applied to the anti-warping mechanism during the retreat of the pressure roller.

[0008] Preferably, support legs are welded to the bottom of the frame, and the number of the support legs is four. The support legs are arranged to provide support for the whole.

[0009] Preferably, the anti-warping mechanism comprises a support frame fixedly connected to the adjustment seat, a slide bar is slidably connected inside the vertical part of the support frame, one end of the slide bar is fixedly connected to a limit block, the other end of the slide bar is fixedly connected to a connecting plate, the bottom of the connecting plate is fixedly connected to a pressure strip, the pressure strip is in contact with the polarizer, and a spring is sleeved on the outer side of the rod body of the slide bar. By setting the anti-warping mechanism, the end of the polarizer can be pressed to play the role of anti-warping.

[0010] Preferably, one end of the spring is fixedly connected to the connecting plate, and the other end of the spring is fixedly connected to the supporting frame. By setting the spring, elastic force can be applied to the connecting plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model arranges an adjustment seat, a motor, a threaded shaft, a moving block, a connecting column and other components between the cylinder and the pressure roller. After the pressure roller is pushed by the cylinder and contacts the polarizer, the motor is used to drive the threaded shaft to rotate forward and reverse, thereby controlling the lateral movement of the moving block, so that the pressure roller can roll back and forth to press the polarizer back and forth, reducing the presence of bubbles.

[0014] 2. The utility model sets an anti-warping mechanism on the side of the adjustment seat. The pressure strip in the anti-warping mechanism will contact the polarizer synchronously with the pressure roller, thereby pressing the end of the polarizer to prevent warping. During the re-lamination process of the pressure roller, a thrust will be applied to the anti-warping mechanism, so that the pressure strip will be separated from the polarizer, thereby not affecting the re-lamination operation.
