Description

Sticking device

technical field

The utility model provides a sticking device, especially using the air pressure to put the first air chamber in a positive pressure, so that the soft film drives the film to be in a convex shape with the center shrinking outward, so that the film is sequentially pasted from the center to the outside. On the glass substrate, the film can be flattened on the glass substrate.

Background technique

With the trend of miniaturization of computer size, instant computing and image processing, large memory capacity and high transmission speed, cathode ray tube displays have been gradually replaced and eliminated, from large displays such as desktop monitors to portable The small displays of terminals are all replaced with LCD panels. Therefore, LCD panels must meet the requirements of high brightness, low power consumption, and high resolution. I believe that in the near future, not only electronic computers, notebook computers, desktops, etc. LCD panels will be used in computer screens, PDAs, and mobile phones. Even products with future potential such as e-books and information appliances will become important applications of LCDs, making LCDs expected to be integrated into human life. Closely combined to become an indispensable part of daily life.

The key point is the application of the polarizer. The polarizer is a light plate that only allows light in a certain direction to pass through. In the process of making a liquid crystal panel for a display, one piece must be used at the front and one at the back, and placed in a staggered direction. In, the main purpose is to make the light source produce a phase difference to show a light and dark state when there is an electric field and no electric field, and to display subtitles or patterns.

However, after the previous production process of the polarizer is completed, a layer of release film will be pasted on the surface to protect the integrity of the polarizer surface, avoid dust, dust or impurities, and reduce scratches caused by collision or stacking or pad damage, and the past manufacturers mostly use horizontal biasing machines to apply the film to the board, place the board to be processed on the conveyor belt, and use the conveyor belt to move the board in the horizontal direction. And the adhesive film is pressed from bottom to top to the surface of the board through the film sticking wheel set above the conveyor belt, so that the adhesive film can be attached to the surface of the board with the horizontal movement of the board. The vibration and displacement generated will cause the plate to vibrate and shift, which makes it difficult for the film to fit properly and stably on the surface of the plate. In addition, because the film is pasted from one end of the plate to the other end, if the area of the plate increases or When the length increases, the bonding stroke will be wider and longer, which will cause air bubbles or uneven wrinkles between the board and the film, which will greatly increase the defect rate, and even because of this serious technical bottleneck, However, it is impossible to carry out the surface-coating process for overly large or overly long panels. For example, in the case of LCD panels, which are currently extremely expensive and increasingly in size, if the defect rate of finished products cannot be reduced, the manufacturing cost will increase. All kinds of deficiencies and production reduction will greatly reduce the overall added value.

Therefore, how to solve the problem and deficiency that the commonly used adhesive film cannot be flattened on the surface of the board is the direction that relevant manufacturers engaged in this industry are eager to study and improve.

Contents of the invention

A sticking device of the present invention comprises a first platform and a second platform, the first platform is provided with a positioning device for positioning the glass substrate on the surface facing the second platform; The surface of the first platform has a positioning device, and the inside of the second platform is formed with an opening adjacent to the side of the first platform for accommodating the positioning device and the glass substrate, and a film is attached to the side wall of the second platform. And aligning the soft sheet of the glass substrate, the soft sheet is located in the accommodating space to form an elastic arc-convex deformation part, and the soft sheet is separated from the accommodating space and forms a first gas hole on the other side of the opening. One side of the first air chamber is provided with an air guide channel for air to enter to pressurize and push against the soft sheet so that the film is sequentially pasted on the surface of the glass substrate from the center to the outside.

The main purpose of this utility model is to use the air guide channel to introduce air so that the first air chamber is in a positive pressure state, and the positive pressure will push against the deformation part of the soft sheet, so that the film will produce an arc that shrinks from the center to the outside along with the deformation part. Convex, the film can be pasted on the glass substrate in sequence from the center outward, and the air between the film and the glass substrate can be discharged outward with the sticking action due to the force applied from the center to the outside. After the lamination is completed, the generation of air bubbles can be avoided, thereby achieving the purpose of improving the yield of the finished product.

The secondary purpose of this utility model is that the film can be pasted on the glass substrate sequentially from the center to the outside following the arc convex of the deformed part of the soft sheet, the first platform, the second platform or the action of the height controller , because the sticking distance is from the center to the outside, because the sticking distance can be shortened so that the actuating stroke can be reduced to half, and because the stroke is long, it is easy to produce uneven sticking in the process.
