Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a film-shaped photosensitive resin on the surface of a substrate in the process of treating a substrate to be treated, particularly in the process of manufacturing a printed wiring board (hereinafter referred to as a substrate). The present invention relates to a film peeling device for peeling a protective film (hereinafter referred to as a dry film).

[Conventional technology]

The manufacturing process of the substrate includes a step of attaching a dry film to the surface of the substrate, baking the circuit wiring pattern, and performing development to form a circuit wiring pattern of the dry film on the surface of the substrate.

The surface of the dry film attached to the substrate is protected by the film, and it is necessary to remove the film when developing.

Conventionally, the above-mentioned work has been performed manually, and an adhesive tape has been used to make it easier to peel off the protective film.

[Problems to be solved by the invention]

As described above, the conventional process of peeling the dry film protective film from the exposed substrate has the following problems. That is, since the protective film is manually peeled off, a large number of steps are required.

Since the adhesive tape is used, the cost is increased.

There are problems such as.

An object of the present invention is to provide a film peeling device that solves the above problems.

[Differences of the Invention from the Prior Art]

The present invention has a difference in that the conventional manual film peeling process described above is automated.

[Means for solving the problem]

In order to achieve the above-mentioned object, the film peeling apparatus according to the present invention is a film peeling apparatus for peeling a film attached to a plate to be processed, a conveyor that conveys the plate to be processed in a certain direction, and is conveyed by the conveyor. A stopper for temporarily stopping the plate to be processed, a marker that forms a peeling portion at the film tip on the plate to be processed stopped by the stopper, and a groove provided in the circumferential direction of the peripheral surface, , An adhesive roll for sticking and winding from the tip of the film peeled off by the marker and peeling the film from the plate to be processed, and by inserting pins radially set in the groove of the adhesive, the adhesive roll With a film stripping roll for stripping the film wound around, and a conveyor for discharging the film stripped from the adhesive roll by the film stripping roll. That.

〔Example〕

 Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, FIG. 2 is a block diagram showing a film peeling auxiliary mechanism portion in an embodiment of the present invention, and FIG. It is a block diagram which shows a conveyance part.

 The configuration of the present invention will be described with reference to FIG.

A conveyor roll 2 that conveys the substrate 1 is arranged, and a pressing roll 3 that compresses the substrate 1 is arranged on the conveyor roll 2, and is further moved vertically and horizontally by air cylinders 4a and 4b. The marker 4 is rotatably supported on the shaft, and the substrate 1 is attached to the peripheral surface of the marker 4.
An uneven pattern for forming a peeled-off portion of the film is attached to the tip of the marker, and the markers 4 are arranged above and below the pass line L, respectively. Next, a stopper 5 that moves up and down by an air cylinder 5a is installed, and a conveyor roll 2 having a pressing roll 3 is sandwiched between the stopper 5 and a groove 2 having a plurality of grooves.
The book adhesive roll 6 is installed so as to abut on the pass line L. The adhesive roll 6 can rotate freely, and the upper adhesive roll 6 can move in the vertical direction. A film stripping roll 7 having radial pins planted on the circumference is arranged so as to match the grooved portion of the adhesive roll 6. The circumference of the adhesive roll 6 and the tips of the pins of the film peeling roll 7 that are set up intersect with each other. Reference numeral 8 denotes a film feed conveyor, and at one end of the conveyor 8, the film feed conveyor 8 is arranged so as to engage with pins of the film stripping roll 7 and pins of the film stripping roll 7, and to intersect with each other.

A film suction pad 10 to which a flexible hose 9 is connected is installed at the other end of the film feed conveyor 8, and a recovery conveyor 11 is installed below the moving range of the film suction pad 10.

 Next, the operation will be described.

The conveyor roll 2 is rotated by a motor or the like (not shown) to feed the substrate 1. When reaching the position of the stopper 5, a sensor (not shown) detects the tip of the substrate 1 and the stopper 5 is lifted by the air cylinder 5a (arrow a in FIG. 2) to stop the substrate 1. Next, the air cylinders 4a and 4b move the marker 4 downward or upward (arrow b in FIG. 2) to press down the front and back surfaces of the substrate 1, respectively, and the marker 4 moves in the traveling direction of the substrate 1 (second arrow). The arrow c) in the figure, the front and back surfaces of the tip of the substrate 1 are lightly scratched. Due to this scratch, a gap is formed between the protective film on the front and back of the substrate 1 and the dry film, and the protective film 12 is easily peeled off.

After that, the stopper 5 descends and the substrate 1 is sent. As shown in FIG. 3, when the substrate 1 passes between the adhesive rolls 6, the protective film 12 adheres to the adhesive roll 6 and is peeled off from the substrate 1. The protective film 12 adhering to the adhesive roll 6 is then peeled off from the adhesive roll 6 by the film peeling roll 7 and is further hooked and fed to the film feed conveyor 8. In this way, only the protective film 12 is continuously peeled from the front and back surfaces of the substrate 1. When the protective film 12 caught on the film feed conveyor 8 is fed to the other end, a sensor (not shown) detects the protective film 12, and the film suction pad 10 shown in FIG. While adsorbing, the protective film 12 is removed from the film feed conveyor 8. When the film suction pad 10 retracts, the suction is stopped, and the protective film 12 drops onto the recovery conveyor 11 and is conveyed outside the device.

〔The invention's effect〕

As described above, according to the present invention, by automating the peeling operation of the protective film of the dry film, it is possible to reduce a great number of man-hours as compared with the manual work, and the disposable adhesive tape is not used. This has the effect of reducing the amount.
