Description

  The present invention provides a film forming apparatus, and particularly refers to a film forming apparatus in which predetermined sheet materials of various dimensions can be applied to a surface film forming operation, and has a simple structure and positions film pieces of various dimensions on a viscous film layer. A film coating device that does not require vacuum suction or alignment, combines predetermined sheet materials of various dimensions, performs film coating work, makes film coating work quick and convenient, and saves time processes About.

The current manufacturing industry faces the serious problem of labor shortage, and the manufacturing industry is prone to causing pollution to the environment, and in the situation where environmental protection awareness is increasing, conventional processing manufacturing work It also has a huge impact on the mode, and under the influence of factors such as labor and the environment, the manufacturing industry is faced with a problem from the processing industry where labor force is dense when it faces the problem that both artificial and management costs rise. There is pressure on converting into sex dense.
Accordingly, the contractor must respond to the pressure of rising production costs by industrial transfer or the method of attracting foreign workers, or operate the production line automation technology and the industrial mode of jig auxiliary processing, and also the management structure and manufacturing Costs can be further improved, manpower can be reduced, manufacturing man-hours can be saved, and the objective of increasing production capacity can be achieved.

  With the progress of flat display manufacturing technology, the next generation products will move to lighter, thinner, flexible or curved direction design, the purpose of which is to make more precise electronic and electrical products to users. It is to be used. Therefore, each type film of the composition structure of these displays, for example, a polarizing plate of a liquid crystal panel, an antireflection film, an optical film, a touch film, or a flexible AMOLED (Flexible AMOLED) structure upper and lower films, a functional film, a package There is a tendency to be lighter and thinner with membranes, protective membranes, support membranes, etc., and when these types of light and thin membranes are bonded to the binding sheet material, holding, alignment, no bubbles and bonding It has become even easier to obtain a high bonding quality with no traces.

In addition, as shown in FIG. 7, the current method of performing surface film coating processing of sheet material has a vacuum chamber A0 inside the vacuum box A, and a movable bonding wheel A1 installed in the vacuum chamber A0. The suction region A2 is provided in the upper part of the vacuum chamber A0, the non-adsorption region A3 located around the suction region A2 is sealed with an adhesive or a tape to prevent gas leakage of the vacuum box A, and the suction region A2 is A half-plate adsorption platform A21 can be provided to fix the waiting film piece B for bonding, and an object adsorption platform C can be installed above the vacuum box A to adsorb the sheet material processed product C1. It is necessary to suck the vacuum chamber A0 of the box A to bring it into a vacuum state, but the vacuum suction requires a relatively long time and causes a gas leakage phenomenon in the non-adsorption region A3 of the vacuum box A. It is necessary to prevent the film processing work Increase the level of difficulty, corresponding time consuming and process.
In addition, the screen adsorbing platform A21 is pushed up using the rising of the bonding wheel A1 in the vacuum chamber A0, and the film awaiting bonding B placed on the screen engraving adsorption platform A21 is bonded to the surface of the sheet material workpiece C1. The general bonding waiting film pieces B are all considerably thin and soft, and when the bonding ring A1 pushes the halftone plate adsorption platform A21 and the bonding waiting film piece B upward to perform bonding, the halftone plate adsorption platform A21. Is transferred to the surface of the laminating waiting film piece B or the processed sheet material C1, and a net is generated in the processed sheet material C1 to easily become a defective product.

Moreover, what is shown in FIG. 8 is another type of vacuum film processing operation mode, in which a soft film layer A01 is provided at the bottom of the vacuum chamber A0 inside the vacuum box A, and a bonding ring A1 is provided below the soft film layer A01. The suction area A2 is installed at the upper part of the vacuum chamber A0, and the non-adsorption area A3 located around the suction area A2 is sealed with an adhesive or tape to prevent gas leakage in the vacuum chamber A, and the adsorption area A2 can install the halftone plate adsorption platform A21, fix the bonding waiting film piece B, install the object adsorption platform C above the vacuum box A, and adsorb the sheet material processed product C1.
In this way, the bonding wheel A1 is installed outside the vacuum box A, the volume of the vacuum box A can be reduced, the vacuum suction work time of the vacuum chamber A0 is shortened, and the bonding wheel A1 is flexible upward during processing. The film layer A01 is pushed up to push up the halftone plate adsorption platform A21, and the bonding waiting film piece B is bonded to the surface of the sheet material processed product C1, but the bonding ring A1 continues to push up to the flexible film layer A01. The soft film layer A01 is liable to be damaged or ruptured, the soft film layer A01 needs to be replaced regularly, and the vacuum chamber A0 of the vacuum box A is still kept in a vacuum state so that there is no gas leakage. It is necessary to pay attention, and the net shape of the halftone plate adsorption platform A21 is transferred to the surface of the laminating waiting film piece B or the sheet material processed product C1, and the net shape is generated in the sheet material processed product C1 and easily becomes defective.

  The vacuum screen printing type film processing method currently employed is careful when the vacuum state of the vacuum chamber A0 inside the vacuum box A is maintained so that the non-adsorption region A3 around the adsorption region A2 is completely sealed. Necessary, avoiding the occurrence of gas leakage phenomenon, regardless of whether the bonding wheel A1 is installed inside or outside the vacuum chamber A0 of the vacuum box A, both of the halftone plate adsorption platform A21 and the flexible membrane When the layer A01 is easily damaged, and the net-plate adsorption platform A21 mesh is transferred to the surface of the laminating waiting film piece B or the sheet material processed product C1, and the size of the sheet material processed product C1 is different. , The size of the bonding waiting film piece B also changes, and it is necessary to change the dimensions of the adsorption area A2 and the non-adsorption area A3. The non-adsorption area A3 is re-sealed with an adhesive or tape, and the vacuum chamber A0. Gas leak It is necessary to prevent the occurrence of phenomena, processing operations preparatory work more complicated, and inconvenient, many defects that occur during the actual application implementation, there is room for improvement.

  Therefore, when a thin film is pasted on a sheet material in the current vacuum environment and the membrane piece is adsorbed using the vacuum adsorption platform, the adsorption platform adsorbs the membrane piece according to the difference in the size of the sheet material. In order to solve defects and inconveniences that require re-setting different adsorption areas, etc., companies in the industry are required to improve their research.
