[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a film bonding apparatus and a bonding method for bonding a plurality of films in various processes such as automatic assembly.
[0002]
[Prior art]
The process of peeling off the adhesive film to which the adhesive has been applied from the protective film is a method in which the operator peels it off by hand. Specifically, the work is performed in such a manner that the end of the half-cut portion of the attached film is grasped with a finger and the protective film side is pressed with the other hand while peeling off. In this case, the peeled film is peeled off well, but is in a state of zero tension, and sometimes wrinkled.
[0003]
Conventionally, when a peeled adhesive film is bonded to a film to be attached, an operator performs tension control while pulling both ends of the film, and performs an operation while correcting wrinkles. At that time, in order to align the position of the attached film, the operator must repeat the work of adjusting the position by moving the attached film minutely while confirming the position with a loupe or the like. Further, when efficiency and stability are required as in a mass-produced product, it is necessary to use an alignment jig prepared for each product number. When automating this process, the mechanism for checking the position of the supplied film and moving it to the laminating position with high accuracy is complicated, and it is expected that the production cost will increase, so we abandoned the automation. It was.
[0004]
[Problems to be solved by the invention]
The present invention automates the process of laminating films and creates stable quality. Therefore, the film is not scratched or soiled, and there is no film wrinkle that leads to poor appearance after bonding. An object of the present invention is to provide an apparatus capable of automatically attaching an attachment film with high accuracy.
[0005]
[Means for Solving the Problems]
As a result of diligent research to solve such problems, a moving means that can be attached to the film to be bonded while holding the film in a uniform state without wrinkles is used, and a standard provided on the film By determining the amount of movement of the moving means based on the position and angle of both films calculated from the detection result of the mark, it was found that films with uncertain positions can be bonded together with high accuracy at high speed. It has been reached.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 shows an example of the structure of a film sticking apparatus. As a configuration of the apparatus, an adhesive film supply means 6 for supplying the adhesive film 4, an adhesive supply means 7 for supplying the adhesive film 2, an adhesive film is received from the adhesive film supply means, and is attached. It is composed of film moving means 1 for attaching to the film. A holding means 10 for holding the film in a wrinkle-free state is installed at the tip of the film moving means. Moreover, the film fixing means 11 for preventing position shift is installed in the location which bonds to a to-be-adhered film. Furthermore, it is comprised by the position detection means 8 of a to-be-attached film, and the affixing film position detection means 9, and the fiducial mark 3 formed in the to-be-attached film and the fiducial mark formed in the to-be-attached film respectively. 5 is provided. Furthermore, it can also have a film adhesion | attachment means which adhere | attaches two bonded films.
[0008]
Next, the principle of the film sticking apparatus of the present invention will be described. First, the film moving means 1 moves to the attached film supply means 6 and receives the attached film 4. The received pasting film is held by the film holding means 10 in a uniform state without wrinkles. The affixed film moves to the sky above the affixed film position detecting means 9 by the film moving means. Here, the reference mark 5 formed on the adhesive film is detected, and the position and angle of the adhesive film being held are calculated. After the film to be attached 2 is fixed by the film fixing means 11 so that the positional deviation does not occur, the reference mark 3 formed on the film to be attached is detected and fixed by the position detection means 8 to be attached. The position and angle of the film to be attached are calculated. The movement amount of the film moving means is determined based on the position and angle of the obtained film to be bonded and the film to be bonded, and the film and the film to be bonded are bonded together. Thereafter, the films can be bonded to each other by a film bonding means. After the film is attached, the film moving means moves to receive the next attached film. When the film is not pasted on the same film to be pasted, the film fixing means is released, and the next film to be pasted is supplied below the film position detecting means to be pasted.
[0009]
The method for supplying the affixed film and the affixed film may be supplied from another continuous film production line or the like. Either a take-up drum or the like is set in the apparatus, and it is unwound and supplied little by little. But it ’s okay. Further, it is not necessarily continuous, and a method of supplying a film after performing sheet cutting may be used.
[0010]
Since the affixing film is temporarily held by the moving means, it has to be supplied every certain length. Therefore, it is necessary to install a mechanism for supplying each sheet to the attached film supply means or a mechanism for receiving each sheet to the film holding means.
[0011]
Since the position detection is performed after the film is supplied for both the pasted film and the film to be pasted, a certain degree of tolerance is allowed for the deviation of the film feeding position, but the variation in the feeding position must be within the viewing angle range of the position detecting means. I must.
[0012]
The positional deviation after detecting the reference mark greatly affects the pasting accuracy. Therefore, a mechanism for fixing the film must be installed in the film holding means and the work area of the film to be attached.
[0013]
The mechanism for fixing the film is not particularly specified, but it is desirable to use vacuum suction in consideration of the fact that the film is bonded on a surface without unevenness and the mechanism does not contact the film bonding surface. The vacuum suction plate is not particularly defined, but a vacuum suction plate of a type that does not damage the peeled film, has high flatness, and hardly adheres to dust is desirable.
[0014]
The film moving means for moving the pasted film may be any means that can freely control the vertical and horizontal moving speeds and directions and can control with high accuracy. The handling robot is more desirable because it is easy to control and can be easily connected to the next process.
[0015]
The film position detection means is not particularly defined, but a film with good detection accuracy can be selected to greatly affect the bonding accuracy. The position detecting means is preferably a device that recognizes a part or the whole image of the pasting film and the pasting film by the CCD camera.
[0016]
A plurality of the pasting film and the pasting film may already be pasted and the films may be laminated. Further, the number of films to be attached is not necessarily one, and a plurality of sheets may be attached to the film to be attached sequentially or simultaneously.
[0017]
【The invention's effect】
Bonds multiple uncertain films that are supplied with some variation from the supply position at high speed and high accuracy without scratches or dirt, and without any film wrinkles leading to poor appearance after bonding. become able to.
