Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed wiring board receiver used between processes for manufacturing a printed wiring board, and more particularly to a continuous wiring of the printed wiring board placed in a rack while standing up. The present invention relates to a receiver used in the case of doing.

[0002]

2. Description of the Related Art A printed wiring board begins by attaching a photo solder resist coating film for forming a pattern to a copper clad laminate in which a copper foil or the like is integrally attached on an insulating base material. It is completed through various processes such as etching of the copper foil, necessary plating of the pattern, formation of a solder resist, and the like. Moreover, in such a printed wiring board, a large number of such printed wiring boards are continuously formed to reduce the manufacturing cost and make the quality uniform.

By the way, in order to form a large number of such printed wiring boards in a continuous manner, it is general to move between devices in each process and to integrate them for efficient movement. That is, for example, a polishing device for performing necessary polishing on a printed wiring board and a cleaning device for cleaning the printed wiring board after polishing may be separately configured, but such a polishing device and a cleaning device are sometimes used. In the interim, it is necessary to successively and continuously receive, collect, convey, and put in the printed wiring board. Each work such as receiving, accumulating, transporting, etc. is necessary between the other processes, but it is necessary to pay attention to the following in each work.

That is, regarding the printed wiring board and materials before it is completed, attention must be paid to dust adhesion and scratches. This is because dust, damage, etc. may cause a short circuit or disconnection in the conductor circuit of the printed wiring board after completion. Further, for example, even in the case of receiving and collecting such printed wiring boards, since it is necessary to continuously perform this, it is necessary to efficiently perform this.

Therefore, the applicant of the present invention has filed Japanese Patent Application Laid-Open No. 63-2472.
In Japanese Patent No. 31, etc., a device for receiving and accumulating a printed wiring board while standing it on a rack has already been proposed. Since the "printed circuit board transfer device" proposed in the above publication receives and collects the printed wiring board in an upright state and transfers it, it is natural that a large number of printed wiring boards can be collectively transferred. As a result, it is possible to prevent each printed wiring board from rubbing against each other, and to prevent the weight of each printed wiring board itself from being directly applied to other printed wiring boards. Etc. can be performed, which is very advantageous.

However, the conventional "printed circuit board transporting device" as described above is designed to move a subsequent process after accumulating a certain amount of printed wiring boards on it, so that it continuously moves on the carry-in path. Since the next printed wiring board to be sent cannot be continuously received and accumulated, another device for receiving must be put on standby or the carry-in route must be stopped. Stopping the carry-in route makes it impossible to continuously manufacture printed wiring boards, and even if it is replaced with another device that has been put on standby, the carry-in route must be stopped for some time. is there.

Therefore, the present inventor has made various studies on how to continuously receive the printed wiring board without stopping the driving of the carry-in path, and as a result, the present invention is achieved. It was completed.

[0008]

The present invention has been made based on the above-described background, and the problem to be solved is continuous reception of printed wiring boards.

It is an object of the present invention to receive a large number of printed wiring boards that are continuously sent on the carry-in path and can carry them to the next process without stopping the carry-in path. To provide a machine with a simple configuration.

It is in a state where a part thereof is stored, and the temporary receiving arm 50 that supports the plurality of materials W to be transported on its base is in a state of intersecting. Therefore, if the temporary receiving arm 50 descends from this state, the plurality of transported materials W supported on the base are left on the base of the rack 60. The movement of 60 does not pose any obstacle.

As described above, when a predetermined amount of the material W to be transported is loaded on the rack 60, the carry-out path 40 is driven in the reverse direction by a detection device (not shown) that detects this.
The rack 60 on the carry-out path 40 is carried to the next process by the rack carriage 70 or the rack carrying path 80 on which the rack 60 is mounted. Of course, at this time, the next rack 60
Until the time comes, the temporary receiving arm 50 for receiving the material W to be conveyed re-projects onto the carry-out path 40 as described above.

In the embodiment shown in FIGS. 1 and 2, each rack 60 is installed on the receiver 100 and moved to another device by a rack carriage 70 on which the rack 60 is placed. Although an example is shown, it goes without saying that a rack transport path 80 as shown in FIG. 4 may be employed instead of the rack carriage 70. The rack transfer path 80 shown in FIG. 4 is for sequentially setting the racks 60 to the receiver 100, and automatically transfers the rack 60 loaded with a predetermined number of materials W to be transferred to the next step.
