Abstract

PURPOSE:To shorten length of a peeled film discharging conveyor as well as to make a setting floor space smaller, by setting up each peeled film housing vessel in an upper position at the substrate carry-in side little nearer than a film separating position in a conveying passage for a substrate. CONSTITUTION:Each of peeled film housing vessels 7A and 7B is set up at the carry-in side of a printed circuit board 1 little nearer than a film separating position in a conveying passage for this printed circuit board 1, namely, an upper position at the front side little nearer than a separating angle setting plate 5 and a film carry-out mechanism 6, respectively. Thus, since these peeled film housing vessels 7A and 7B are set up in the upper position at the carry-in side of the printed circuit board 1 little nearer than the film separating position in the conveying passage for the printed circuit board 1, length of a peeled film discharge conveyor of the film discharge mechanism 6 can be shortened to some extent. In addition, since these vessels 7A and 7B are set up the upper position of the conveying passage for the substrate 1 and formed into a three- dimensional structure, the setting floor space can be made smaller than ever before.

Description

Detailed Description of the Invention (1) Purpose of the Invention [Field of Industrial Application] The present invention relates to a thin film peeling technique, and in particular,
The present invention relates to a technique that is effective when applied to a technique for peeling off a protective film pasted to protect the surface of a substrate.

[Prior Art] Printed wiring boards used in electronic devices such as computers have a predetermined pattern of wiring made of copper or the like formed on one or both sides of an insulating substrate.

This type of printed wiring board can be manufactured by a first manufacturing process. First, a laminate consisting of photosensitive 4131 resin (photoresist) and a transparent resin film (protective film) for protecting it is laminated by thermocompression onto a conductive layer provided on an insulating substrate.

Thereafter, a wiring pattern film is placed on top of the other, and the photosensitive resin is exposed for a predetermined period of time through this wiring pattern film and the translucent resin film. and.

After peeling off the transparent resin film, the exposed photosensitive resin is developed to form an etching mask pattern. Thereafter, unnecessary portions of the conductive layer are removed by etching, and the remaining photosensitive resin is removed to form a printed wiring board having a predetermined wiring pattern.

[Problems to be solved by the invention]'l of the aforementioned printed wiring board! In the step 5, a step of peeling off the light-transmitting resin film is required when the photosensitive resin is exposed and then developed. Peeling off this translucent resin film relies on the manual labor of four people, and since the film is thin, it requires finger dexterity and great skill to prevent damage or destruction caused by uneven peeling force. It takes.

For this reason, the peeling time of the light-transmitting resin film becomes longer, so there is a problem that the working time becomes longer in the manufacturing process of the printed wiring board.

Therefore, an automatic thin film peeling apparatus has been developed that automatically performs the previous 2M film peeling process mechanically.

This automatic thin film peeling device uses a roller, brush, needle, etc. to lift the edge of the thin film attached to the substrate, lifts up the lifted part and peels it off, and uses a thin film conveyor to remove the peeled thin film. It is designed to automatically store the peeled alkaline wood in an external container.

However, in this automatic thin film peeling device, the peeled thin film is automatically discharged into an external peelable thin film storage container using a peeling thin film conveyor, so a space is required to place the peelable thin film storage container. However, there was a problem in that the space (floor area) occupied by the equipment was large.In addition, there was a problem in that the distance of the peeled thin film discharge conveyor from the thin film peeling position to the external peeled thin film storage container was long. Ta.

The above-mentioned and other problems and novel features to be solved by the present invention will become clear from the description of this specification and the accompanying drawings.

(2) Structure of the Invention [Means for Solving Problems] A brief overview of one typical invention disclosed in this application is as follows.

That is, it is a thin film peeling device with a peeling thin film storage container that peels off and discharges a thin film stuck to one or both sides of a substrate, and an upper portion bff of the substrate transport path is slightly closer to the substrate carrying-in side than the thin film peeling position. To.

Each is characterized by a three-dimensional structure in which a peelable thin film storage container is provided.

[Function] The present invention peels off the thin film provided on both sides of the substrate, and uses a peeling thin film conveyor to remove the peeled thin film from the substrate conveyance path a little further from the thin film peeling position. They are automatically discharged into the peelable thin storage containers provided at the upper position. At this time, the length of the peeling thin film discharge conveyor is shortened because the peeling thin film storage containers are disposed at slightly upper positions on the substrate carrying-in side than the thin film peeling position of the substrate conveyance path.

Furthermore, since the peelable thin film storage container is arranged above the substrate transport path to form a three-dimensional structure, the installation floor space is reduced.

[Example] Hereinafter, an example in which the present invention is applied to a protective film removing apparatus for a printed wiring board will be described with reference to the drawings.

In addition, in all the figures of the embodiment, parts having the same functions are given the same reference numerals, and repeated explanations thereof will be omitted.

FIG. 1 shows the protective film removed from a printed wiring board according to an embodiment of the present invention! Figure 2 is a side view of the printed circuit board with the cover removed, and Figure 3 is a side view of the printed circuit board with the cover removed. FIG. 2 is a cross-sectional view showing the configuration of a wiring board.

Peeled heel thin film discharge conveyance section IV, peeled thin film discharge storage section Vt/V2. It consists of a control unit (■) and a display device (■) that notifies defective products, failures, and operation errors.

As shown in FIG. 2, the conveyance mechanism for the printed wiring board in the protective film peeling apparatus of this embodiment is mainly composed of a conveyance drive roller 2 that conveys the printed wiring board.

The protective film peeling device of this embodiment includes a protrusion pressing mechanism 3, a fluid spraying mechanism 4,
A peeling angle setting plate color and a thin film delivery mechanism 6 are provided.

Moreover, as shown in FIG. 3, the printed wiring board 1 is
A photosensitive resin (photoresist) layer IC and a transparent resin film (protective film) I to protect it are formed on a conductive layer ID provided on both sides (or one side) of an insulating substrate IA made of resin or the like.
It is formed by thermocompression laminating a laminate consisting of D.

The defective product occurrence, failure, and operation error notification display device ■ is as follows:
For example, the lower part is displayed in yellow to notify that a defective product has occurred, and the upper part is displayed in red to notify that a failure or operational error has occurred.

Peelable thin film housing section V1 of this embodiment. As shown in FIGS. 1 and 2, V2 is a translucent resin film ID pasted on both sides of the printed wiring board 1 by the protrusion pressing mechanism 3, fluid spraying mechanism 4, and peeling angle setting. The thinned transparent resin film ID is peeled off using the plate 5 and the film carrying out mechanism 6, and the thin film carrying out mechanism 6 automatically collects the peeled thin film storage containers 7A and 7B into the peeled thin film storage containers 7A and 7B. It is supposed to be done.

As shown in FIG. 1, the peeling thin film storage containers 7A and 7B are placed on the carry-in side of the printed wiring board 1, that is, the peeling angle setting plate 5 and They are disposed at upper and lower positions in front of the thin film transport mechanism 6 (on the left side in the figure), respectively.

In this way, the peeling thin film storage containers 7A and 7B are disposed slightly above and below the thin film peeling position h1 of the conveyance path of the printed wiring board Fi1 on the carry-in side of the print 1-wiring board 1, so that the thin film carrying-out mechanism The length of the peeling thin film conveyor No. 6 can be shortened.

Further, since the peelable thin film storage containers 7A and 7B are arranged above and below the conveyance path of the printed wiring board 1 to form a three-dimensional structure, the installation floor area can be reduced.

The most basic aspect of the peelable thin film storage containers 7A and 7B of this embodiment is that all of the side plates constituting the peelable thin film storage containers 7A and 7B are made of plate-like bodies.
Preferably, the side plate is made of a member that allows air to circulate between the inside of the peelable thin film storage containers 7A and 7B and the outside of the container.

Examples of such members include 1, for example, a plate-shaped body with an elongated shape;
Platy bodies, mesh bodies, grid bodies, rods, or linear bodies formed with cutouts (slits) of any shape, including rectangular, square, circular, and anisotropic shapes, in the same direction or intersecting. Examples include those arranged at arbitrary intervals.

The sizes of the notches, grids, etc. need to be large enough to prevent the items stored in the peel fJJ and thin film storage containers 7A and 7B from coming out.

Furthermore, the cutouts and the like may be provided on the entire surface of the side plate or may be provided partially, but when provided partially, it is preferable to form them in the upper half than in the lower half.

Further, the peelable thin film storage containers 7A and 7B may be a combination of a plate-like body without a cutout and a plate-like body with a cutout or the like.

Further, the peeling thin film storage containers 7A and 7B may be attached to the main body of the thin film peeling apparatus by any method such as fixed, detachable, or slidable.

Further, the peelable thin film storage containers 7A and 7B may be constructed so that the side plates can be opened and closed, and in particular, when they are fixed, it becomes easy to take out the stored items.

For example, the peeling thin film storage containers 7A and 7B may be attached with rollers at the bottom of each of them, and a rail may be provided on the main body of the thin film peeling device so that the peeling device can be pulled out. Thin film storage container 7
The lower corner edges of each of A and 7B may be used as supports and configured to be rotatable so that the contents can be taken out.

Also applicable! (Of J membrane storage containers 7A and 7B.

Regarding the peelable thin film storage container 7A disposed at the upper position, it is often configured such that the side where it is discharged from the discharge conveyor and dropped is lowered and inclined compared to the other side. It is possible to prevent the peelable thin film storage container 7A from falling not only in normal times but also when vibration occurs, thereby improving stability.

Note that the constituent material of the peelable thin film storage containers 7A and 7B is not particularly limited, and may be made of any material such as full bending, synthetic resin, wood, etc.; This is convenient because the amount can be checked from the outside at a glance.

By configuring as described above, the peelable thin film storage container 7
Since A and 7B are provided with a notch (slit) in the side plate (with the bottom cut out if necessary), they can reliably store items commensurate with the internal volume of the peelable thin film storage containers 7A and 7B. be able to.

That is, for example, a thin film such as a peeled thin film, which is the object of this embodiment, is placed in the peeled thin film insertion part Fa using natural falling.
When trying to store in 7A and 7B.

Due to the influence of the air existing inside each of the peeling/LV membrane storage containers 7A and 7B, they may be stored partially folded, making it impossible to fully utilize the internal volume of the peeling thin film storage containers 7A and 7B. .

In particular, when the thin film body is guided and discharged using an air flow, the air used there will fall into the peelable thin film storage containers 7A and 7B while being entangled with the thin film body. Then, the falling thin film body is brought into the peelable thin film storage containers 7A and 7B with air trapped on the lower surface,
Since the pressure of the air acts on the falling thin film, it does not fall into a predetermined place.

It falls in the wrong position. In such a case, the degree of folding and curling becomes even more severe, and effective storage becomes a ring.

Further, even if they fall in a predetermined place, they do not overlap each other and a thick layer of air is trapped between the thin sheets, so they cannot be stored compactly.

On the other hand, the peelable thin film storage container 7 of this embodiment has a special structure.
A and 7B have cutouts (slits) for the air in the containers, so that the air in the peelable thin film storage containers 7A and 7B is pushed out by the thin film bodies, reducing the air resistance exerted on the falling thin film bodies. , there is no problem as mentioned above, and the thin film bodies can be stored in the peelable thin film storage containers 7A and 7B in a compact stacked state, and the inner volume of the containers is 12
You can store items that match your child's needs.

Furthermore, the amount of stored contents can be confirmed through the notches provided in the peelable thin film storage containers 7A and 7B, making it possible to easily manage one operation.

Further, as shown in FIGS. 1 and 2, a peeling thin film guiding member 10 as shown in FIG. Attach 1111 to the cover of part 1 through mounting hole 10A.
11, it is rotatably attached. As shown in FIG. 4, an air vent cutout (slit) 10B is provided on the side of the hard-to-peel thin film guiding member 10. As shown in FIG. In this way, in the negative part of the peelable thin film storage container 7A! (It is possible to prevent the peeling film from rising due to air flowing on the upper surface of the peeling film.

The present invention has been specifically explained above based on examples, but
It goes without saying that the present invention is not limited to the embodiments described above, and can be modified in various ways without departing from the spirit thereof.

(3) Effects As explained above, according to the present invention, the first effect can be obtained.

Since the peeling thin film storage container is disposed at a slightly upper position on the substrate carry-in side than the thin film peeling position of the substrate conveyance path, the length of the peeling thin film discharge conveyor of the thin film carrying-out mechanism can be shortened.

In addition, since the peelable thin film storage container is disposed above the substrate conveyance path and has a three-dimensional Mc construction, the installation floor area can be reduced.

In addition, the peelable thin film storage container has a notch in its constituent side plate (with a bottom cut out if necessary), so that the air inside the peelable thin film storage container is pushed out when storing the peeled thin film. The exfoliating thin film can be reliably housed inside.

Furthermore, the amount of stored contents can be checked through the notch provided in the peelable thin film storage container, making it easier to manage operations.
