Description

Film-adhesive device capable of removing bubbles

The invention relates to a film sticking device, in particular to a film sticking device capable of removing air bubbles.

If the existing crystal grain is adhered to the film, if the grain needs to be turned over to a new film, the automatic picking device is used to transfer the grain from the original film to the new film. This step is very expensive. Time.

However, in the process of sticking the film to the die, the conventional film sticking device is prone to bubble residue between the die and the film, so when the grain needs to be turned over to a new film, The relationship of the bubbles makes the bonding degree between the crystal grains and the film too poor, so that there are still crystal grains remaining on the old film during the transfer process of the grain turning, so the bubble residue is a problem that must be solved.

One of the objects of the present invention is to provide a film sticking device capable of removing bubbles, which can remove bubbles between the film and the target.

The invention provides a film sticking device capable of removing bubbles, wherein the device comprises a base for placing a target object; and an air bag is disposed above the base, the air bag having a first state and a first state when contacting the target object Two states.

Please refer to FIG. 1 . FIG. 1 is a schematic perspective view of a film sticking device capable of removing air bubbles according to the present invention. In the embodiment, the film sticking device 100 for removing air bubbles comprises a base 101 and an air bag 102 .

The pedestal 101 is used for placing a target object, and the film-adhesive device 100 capable of removing air bubbles can be attached to the surface of the target by the adhesive film; The airbag 102 is disposed above the base 101. In other words, the airbag 102 is disposed above the die, and has a first state and a second state when the airbag 102 contacts the target.

Please note that the target of the present invention may be a crystal grain or a glass. The plate, the flat plate and the ceramic plate are realized at the time. For the sake of simplification of the description, the following is a exemplification of the die, but the invention should not be limited thereto.

Please also refer to Figure 2, Figure 2 is a removable In the present embodiment, the airbag 102 has a hollow structure, and the airbag 102 has an elastic pad 102a inside, and the elastic pad 102a is disposed and fixed on the inner edge of the airbag 102. . In another embodiment, the resilient pad 102a can be realized by a resilient rubber pad.

In addition, the film-adhesive device 100 capable of removing bubbles comprises: A pressure controller is coupled to the airbag 102 for controlling the internal pressure of the airbag 102 to a certain value, so as to prevent the airbag 102 from being squeezed by the airbag 102 during the process of the adhesive film on the surface of the die. The surface of the film is such that bubbles remain between the film and the crystal grains, so that the surface of the film is irregularly deformed and not flat.

In an embodiment, the bubble sticking device capable of removing bubbles The 100 has a hole O, and the pressure controller connects the hole O and inflates or deflates, and the internal pressure of the air bag 102 is maintained at a constant value by the conversion of inflation and deflation.

Please also refer to Figure 3, which is the base of the present invention. In the present embodiment, the device 100 is not yet in operation, and the airbag 102 is still in an initial state. Below the airbag 102 is a die W. The die W is placed on the susceptor 101. The upper surface of the die W has an isolation member K. The spacer member K is disposed between the upper surface of the die W and the adhesive film 10, and the spacer member K It is used to isolate the die W from direct contact with the film 10, and to prevent the film-adhesive device 100 capable of removing bubbles from sticking to the film 10 when not activated. In an embodiment, the spacer element K can be realized by a release film or a stainless steel sheet.

In addition, in order to facilitate the relative position of the components, the grain W The film 10, 11 and the spacer element K are not shown to scale.

Please note here that in this example, the third picture is from above. The film is sequentially followed by the film 10, the spacer member K, the die W, the film 11, and the susceptor 101. The surface under the grain W is adhered to the film 11, and if the grain W needs to be adhered by the film 10, the spacer K only needs to be removed from the area to be pasted, and the device 100 uses the air bag 102 to be pressed down. In the middle, the film 10 is adhered to the desired crystal grains W.

In addition, the airbag 102 can be disposed on a lifting mechanism 103. When the lifting mechanism 103 is lowered, the airbag 102 can be brought into the first state and the second state. In one embodiment, the lifting mechanism 103 is raised and lowered in the direction D1 and perpendicular to the base 101.

Please refer to Figure 4, Figure 4 is the airbag contact of the present invention. A schematic view of the side of the film. The elevating mechanism 103 is lowered in the direction D1, at which time the surface of the airbag 102 starts to contact the film 10, and it is noted that in the present embodiment, the air bag is realized by a semicircular airbag. Since the airbag 10 has a semicircular surface, when the elevating mechanism 103 descends in the direction D1, the airbag 10 contacts the surface of the adhesive film 10 from the center point G.

Please also refer to Figure 5, which is removable for the present invention. Schematic diagram of the bubble film sticking device in the first state. In the first state, the center point of the airbag 102 contacts the surface of the film 10, and at this time, the airbag 102 contacts the film 10. Since the internal pressure of the airbag 102 is constant, the airbag 102 generates surface deformation by using internal pressure and then extrudes the glue. The air between the membrane 10 and the crystal grain W, at this time, the gas in the airbag 102 is pressed outward along the arrow, and the air between the film 10 and the crystal grain W is extruded together to avoid the adhesive film 10 and There are bubbles between the grains W.

Please refer to FIG. 6 again, and FIG. 6 can be removed according to the present invention. A schematic diagram of the bubble film sticking device in the second state. When the airbag 102 is switched to the second state in the first state, the contact between the airbag 102 and the surface of the film 10 is switched from the center point G to the surface of the airbag 102, in other words, the airbag 102 is adjusted by the point contact to the film. Contact on the 10th.

Please note here that the base 101 has a heater (Fig. The heater system can raise the temperature of the susceptor 101, so the film 10 is softened by heating by the heater to increase the adhesion. When the softened film 10 is pressed by the airbag 102 to the grain W, Its adhesion increases, meaning That is, when the film 10 is in the second state, the crystal grains W are more closely bonded to the film 10.

In addition, when the airbag 102 is in the second state, the elasticity The pad 102a indirectly contacts the film 10 and the die W through the air bag 102, and the elastic pad 102a applies pressure to the film 10 and the die W, so that the degree of bonding between the die W and the film 10 can be enhanced, and the airbag 102 and the glue are maintained. The contact surface of the film 10 is flat.

In summary, the bubble sticking device 100 capable of removing air bubbles The adhesive film is pressed into the crystal grain by a balloon with a fixed pressure to remove the air bubbles between the film and the crystal grain, and then the elastic pad inside the air bag is used to flatten the upper surface of the film adhered to the die.
