[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a punching device for punching perforations in a printed circuit board.

[0002]

2. Description of the Related Art Conventionally, in order to obtain a printed circuit board on which a chip such as an IC is mounted, first, an electric component chip is mounted on one side or both sides of the base printed circuit board, and then the outer shape of the printed circuit board is removed from the base printed circuit board. The product is punched out. The above-mentioned base printed circuit board is perforated so as to draw the outer shape of the printed circuit board that will be the product, and constitutes a mounted printed circuit board on which electrical components are attached inside the perforated line and outside the perforated line. An outer frame is formed as a supporting portion when punching. Then, the above-described perforated connection portion is punched and cut to separate the mounted printed circuit board as a product from the outer frame.

[0003]

Conventionally, as described above, in order to punch the connecting portion of the perforations, a punching die matching the perforations of the base printed circuit board is prepared, and the perforation is performed by one press. The connecting parts provided at several places are punched and cut. However, recently, because the model change of the printed circuit board is performed in a short cycle, it is necessary to prepare a new punching die that is expensive and time-consuming for each model change. It was very difficult to deal with.

The present invention has been made in view of the above-mentioned conventional circumstances, and it is an object of the present invention to provide a perforation punching means which can easily cope with a change in the perforation pattern of a base printed board.

[0005]

In order to solve the above-mentioned problems, the punching device of the present invention comprises a punching machine for continuously driving a shaft-like punch with respect to a die, and a printed board to be processed. Holding means for holding on a reference plane set between the punch and the die, and at least one of the holding means and the punching machine are moved in the X direction and the Y direction orthogonal thereto with reference to the reference plane. A feed mechanism that freely supports and a control unit that controls the operation of the feed mechanism are provided, and the control unit moves at least one of the punching machine and the holding unit by the set amount in the X and Y directions by the feed mechanism. While continuously controlling the relative positional relationship between the punch of the punching machine and the printed circuit board held by the holding means, the punch that continuously drives is printed. It is made provided with XY control means for moving along the perforations of the plate.

In the punching device according to the second aspect of the present invention, the printed circuit board held by the holding means is a base printed circuit board in which mounting components are attached to a portion surrounded by the perforated lines, and the perforated line in the base printed circuit board is provided. A support body that supports a mounted printed circuit board portion surrounded by the above so as to be contactable and separable from below, and a holding arm that cooperates with the support body to hold an outer frame formed outside the perforation so as to be contactable and separable from both sides. The holding means is constituted by.

Further, in the above-mentioned punching device, the base printed board is carried into the punching position by the carrying-in means, the perforations of the base printed board are punched, and the printed board is mounted on the inside of the perforations and the perforations. After the outer printed frame is separated from the outer frame, it may be installed at a punching position of a working line where the mounting printed circuit board is carried out from the punching position by carrying-out means.

[0008]

According to the above means, the punching machine is provided with a shaft-shaped punch, and this punch is continuously driven to the die. A reference surface is formed between the punch and the die, and the pudding substrate held by the holding means is located on the reference surface. At least one of the punching machine and the holding means is supported by a feed mechanism so as to be movable in the X and Y directions. Then, the XY control means of the control unit for controlling the operation of the feeding mechanism moves at least one of the punching machine and the holding means by a set amount in the X and Y directions, and a printed circuit board held on the reference plane. The amount of movement of at least one of the punches in the X and Y directions is controlled, thereby arbitrarily controlling the relative positional relationship between both, that is, the punch and the printed circuit board that are continuously driven. According to this
The punching position of the punch is moved along a predetermined line of the printed board, and the holes punched by the axial punch are continuously connected to be punched linearly.

According to a second aspect of the present invention, the supporting body of the holding means supports the mounting printed board portion in the base printed board so that the mounting printed board portion can be contacted and separated from below, and at the same time, the holding arm of the holding means supports the base printed board. By holding the outer frame portion so that it can be contacted and separated from both sides, the base printed circuit board, which is a printed circuit board, is held on the reference surface. When the punching of the perforations is completed, the base printed board is separated into the mounting printed board and the outer frame. The mounted printed circuit board separated by the punching process is supported from below by the support of the holding means, and the outer frame is held from both sides by the holding arms. Therefore, it is possible to immediately pick up the mounted printed circuit board, which is the product, and move it to the next step after punching, and the outer frame, which is the scrap material, can be improved by separating the holding arm and the support. It falls and is collected.

[0010]

As described above, according to the present invention, at least one of the punch of the punching machine and the printed circuit board held by the holding means is movably supported by the feeding mechanism, and the reference plane is controlled by the XY control means. In which the punches linearly punch the perforations of the printed circuit board by controlling the relative positional relationship between the punch and the printed circuit board while moving in the X and Y directions by a set amount. Is. Therefore, even if the pattern of perforations is changed due to the model change of the printed circuit board, it can be easily dealt with only by changing the control of the punching position performed by the XY control means. Further, since the punching die used conventionally is unnecessary, it is possible to reduce the time and cost for producing the die.

Since the punching device according to the second aspect of the invention is configured such that the mounting printed circuit board of the base printed circuit board on which the mounting components are mounted and the outer frame are separately supported by the support of the holding means and the holding arm. After punching the perforations, it is possible to efficiently pick up the mounted printed circuit board as a product and collect the outer frame as a scrap material.

Further, in the punching device described above, the base printed board is carried into the punching position by the carrying-in means, the perforations of the base printed board are punched, and the mounted printed board separated from the outer frame is punched out by the carrying-out means. Since it is installed on the processing line that is carried out from the position, the base printed circuit board can be carried in and out of the punching device automatically, and the perforation punching can be performed more efficiently.
