Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a carrying tool which is convenient for carrying a thin photosensitive material.

[0002]

[Prior art]

 As a case of conveying a thin photosensitive material, for example, a manufacturing process of PWB (Printed Wired Board) will be described as an example, an automatic conveying system is adopted for automation. In the PWB manufacturing process, especially in the exposure step, a photosensitive DFR (Dry Film Resist) is laminated on the substrate to form a thin photosensitive material. Have a huge impact. That is, the automatic transfer of the substrate from the laminator to the exposure device and from the exposure device to the development device must be performed carefully so as not to damage or stain the substrate, which is a thin photosensitive material. At the same time, however, it has been desired to increase the transport speed in order to improve productivity, and it has been extremely difficult to achieve both at the same time.

Specific examples of a conventional method for transporting a thin photosensitive material are shown in FIGS. 4 and 5. FIG. 4 shows a method in which the four corners of the DFR-laminated substrate 1 are adsorbed by four vacuum pads 3 provided in a transport unit (not shown), and the transport unit is moved to transport the substrate 1. FIG. 5 shows a method in which a substrate 1 processed by a processing device such as a laminator or an exposure device is once transferred onto a belt 7 of a belt conveyor 5 and is conveyed by driving the belt 7.

[0004]

[Problems to be solved by the device]

 However, in the vacuum pad method of FIG. 4, since there is a high possibility that the DFR is damaged or contaminated at the part where the pad 3 contacts the substrate 1, it cannot be expected to manufacture a good product from that part.

In addition, in the belt conveyor system of FIG. 5, it takes time to transfer the substrate 1 from the processing device to the belt 7, and the belt conveyor inherently increases the amount of dust generated when the traveling speed is increased. Therefore, there is a problem in that the defective rate of the product increases when it is conveyed at high speed. The present invention has been devised in view of the above circumstances, and an object of the present invention is to enable high-speed transportation without damaging or contaminating a thin photosensitive material, and to improve the productivity of products using the thin photosensitive material. It is to provide a carrier that can improve

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a carrier according to the present invention is made of a material having a predetermined rigidity, and a carrier main body extending a predetermined length along an edge of a thin photosensitive material; and the carrier. The main body and the edge portion of the thin photosensitive material are configured to be detachably coupled to each other.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a thin photosensitive material and a stacker to which a carrier is attached. Reference numeral 11 denotes a thin photosensitive material, 13 denotes a carrier, and the thin photosensitive material 11 is a substrate for PWB. The thin photosensitive material 11 is formed in a rectangular shape with two vertical sides 1101 and two horizontal sides 1103. The carrier 13 is attached to one lateral side 1103 of the thin photosensitive material 11, and the carrier 13 has substantially the same length as the lateral side 1103, so that the flatness of the thin photosensitive material 11 is ensured. In addition, it is formed of a member having a predetermined rigidity such as a synthetic resin or a lightweight alloy. The transport tool 13 is composed of a flat plate portion 15 and two leg plate portions 17 protruding from the flat plate portion 15, and the lateral side 1103 of the thin photosensitive material 11 with the two leg plate portions 17 opened by an appropriate jig. Is inserted between both leg plate parts 17, and when the open state is released, the two leg plate parts 17 return to their original state by elasticity, and the lateral side 1103 of the thin photosensitive material 11 is fixed. ing. Therefore, in this embodiment, the flat plate portion 15 corresponds to the carrier body and the leg plate portion 17 corresponds to the connecting means.

According to the present embodiment, since the carrier 13 is attached to the thin photosensitive material 11, the carrier 13 having various structures for gripping and locking the carrier 13 changes from the laminator to the exposure device. In addition, it is possible to automatically convey the thin photosensitive material 11 at high speed while preventing damage and contamination of the DFR from the exposure device to the developing device.

An example of conveyance using the conveyance tool 13 will be described. In FIG. 1, reference numeral 19 denotes a stacker for a thin photosensitive material. When the conveyance tool 13 is attached to the thin photosensitive material 11, such a stacker 19 is used. Thus, the five thin photosensitive materials 11 can be conveyed at one time. More specifically, the stacker 19 has a vertical side 1901 and a horizontal side 1903 that are larger than the vertical side 1101 and the horizontal side 1103 of the thin photosensitive material 11, and is formed in a rectangular parallelepiped shape. Two light-shielding rooms are formed. A slit 1905 into which the two leg plate portions 17 are inserted and the flat plate portion 15 is locked is formed on each light-shielding chamber on the upper surface of the stacker 19.

When the thin photosensitive material 11 is conveyed, first, the thin photosensitive material 11 is inserted from the slit 1905 into each light-shielding chamber, the two leg plate portions 17 are inserted into the slits 1905, and the flat plate portion 15 is inserted. Are locked on both sides of the slit 1905. As a result, the thin photosensitive material 11 is stored in the stacker 19 while being shielded from light. By appropriately transporting the stacker 19 itself by the transporting means, the five thin photosensitive materials 11 are transported at once without being in contact with each other in a light-shielded state.

Next, a second embodiment will be described with reference to FIGS. 2 and 3. FIG. 2 is a perspective view of the thin photosensitive material to which the carrier according to the second embodiment is attached. 21 is a thin photosensitive material, and 23 is a conveying tool. The conveying tool 23 is attached to one lateral side 2103 of the thin photosensitive material 21, and the conveying tool 23 has substantially the same length as the lateral side 2103. Like the above-mentioned embodiment, it is formed of a member having a predetermined rigidity such as a synthetic resin or a lightweight alloy. The carrier 23 is composed of a substrate 25 having an L-shape in a side view, and a vertical plate 27 that is removably attached to the substrate 25 with screws or the like.

As shown in FIG. 3, the vertical plate 27 is provided with two positioning pins 29, and the positioning pins 29 are positioned along the lateral side 2103 of the thin photosensitive material 21. The carrier 23 is attached to the thin photosensitive material 21 by inserting the vertical plate 27 to the substrate 25 in this state with a screw or the like. In the second embodiment, the substrate 25 corresponds to the carrier body and the vertical plate 27 corresponds to the coupling means. Also in the second embodiment, the DFR is transferred by the carrier tool 23 as in the above embodiment. It is possible to automatically convey the thin photosensitive material 11 at high speed while preventing damage and contamination of the thin photosensitive material 11.

It should be noted that, in the embodiment, the case where the length of the carrier tool body is the same as one side of the thin photosensitive material has been described. However, the carrier tool body need not have the same length, and in short, the carrier tool body is thin. It may be shorter or longer than one side of the photosensitive material as long as it does not hinder the conveyance. Although the thin photosensitive material has a rectangular shape in the embodiment, when the thin photosensitive material has, for example, a circular shape, the carrier body has an arc shape instead of a straight line shape. The shape of is determined by the shape of the thin photosensitive material.
