Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for automatically positioning an article handled by a manufacturing apparatus or the like, and more particularly to a technique effective for use in an apparatus configured to position an article to be handled such as transportation with a pin. It is a thing.

[0002]

2. Description of the Related Art For example, when an electronic component such as a semiconductor device is mounted on a printed circuit board which is carried in / out at regular intervals, the printed circuit board must be accurately positioned in order to eliminate mounting mistakes. There is. Conventionally, when positioning a printed circuit board, a backup pin has been used as a positioning member, and the backup pin is set by screwing or pin insertion / removal when switching the type (specification). Conventionally,
These operations are performed manually by the staff.

[0003]

According to the study by the present inventor, the positioning technique for manually setting the backup pin has a problem that it takes time to set the backup pin and it takes time to perform setup and model change. is there.

Therefore, an object of the present invention is to provide a technique capable of automating the setting of a backup pin for positioning an article.

The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.

[0006]

Among the inventions disclosed in the present application, a brief description will be given to the outline of typical ones.
It is as follows.

That is, a plurality of backup pins for restricting the position of the article to be handled, a plurality of arms capable of rotating the backup pins once in the horizontal direction, and a drive means for rotating and linearly moving each of the arms. A plurality of rails for guiding the linear movement of the arm are provided.

[0008]

According to the above means, the backup pin rotates in the horizontal direction, that is, in the X direction, and in the Y direction, and the arm supporting the backup pin is Z.
You can move freely in any direction. As a result, the positioning of the article to be handled can be automatically set, and the backup pin for positioning the article can be automatically set in a short time.

[0009]

[Embodiment 1] FIG. 1 is a plan view showing a first embodiment of an automatic positioning device according to the present invention. FIG. 2 is a partial front view showing the details of the automatic positioning mechanism.

A plurality of rails 2 are installed in parallel on the table 1, and one reverse L-shaped backup support arm 3 is rotatably disposed on each of the rails 2 so as to be movable. A backup pin 4 for fixing an article (for example, a printed circuit board) is vertically attached to each tip of the backup support arm 3. Further, as shown in FIG. 2, an elevating cylinder 5 that is moved up and down by using air pressure or a motor as a drive source is attached to the shaft portion of the backup support arm 3. Then, the coordinates in each direction of the X, Y, and Z axes due to the movement of the backup pin 4 are set as a table having a unique relationship with the article to be handled, and this data is stored in the storage medium of the storage device. . It should be noted that in a manufacturing plant or the like, the automatic positioning device configured as shown in FIG.
It constitutes one system.

In such a structure, the backup support arm 3 can be moved on the rail 2 in the Y-axis direction by using a motor or the like as a drive source, and can be rotated 360 ° about the lifting cylinder 5 as a rotation center. Horizontal rotation is possible at an angle. At this time, the rail 2 functions so that the movement of the backup support arm 3 is easy and stable. The backup pin 4 is used, and its shape and material are appropriately selected according to the article to be handled.

At the time of positioning, data is read from the storage device, and the backup support arm 3, the backup pin 4, and the lifting cylinder 5 are driven based on this data, and the backup is performed so that the article to be handled is positioned at an appropriate position. Pin 4 moves. As a result, the positioning of the article to be handled is automatically performed.

[0013]

Second Embodiment FIG. 3 is a plan view showing a second embodiment of the automatic positioning device according to the present invention. FIG. 4 is a partial front view showing the details of the configuration of the main part of FIG.

In the above-described embodiment, the coordinate movement is performed by the rotation of the backup support arm 3 holding the backup pin 4 and the movement on the rail 2, whereas the present embodiment backs up a large number of backup pins 6. The pin support plate 7 is characterized in that it is arranged at regular intervals and can be moved up and down.

For example, four backup pins 6 are selected according to the size of the article to be handled, only the selected backup pins 6 are driven so as to rise from the surface of the backup pin support plate 7, and the other backup pins 6 are It is not exposed from the surface of the backup pin support plate 7. In this embodiment, it is necessary to have a mechanism for moving the backup pins 6 up and down individually. In this case, which backup pin 6 is to be raised is determined by reading out the data corresponding to the article to be handled among the data stored in the storage device as in the above-described embodiment.

FIG. 5 is a perspective view showing an apparatus to which the automatic positioning apparatus according to the present invention is applied.

At least one of the automatic positioning devices 8 shown in FIG. 1 is arranged inside an automatic machine 9 (for example, an assembly device for mounting components on a printed circuit board).

FIG. 6 is a block diagram showing a control system in the embodiment of FIG.

Each of the backup pins 6 is provided with a sensor 10 for detecting whether or not it is driven (that is, the coordinates of the backup pin 6), and a data converter 11 is connected to the output terminal thereof. An arithmetic processing unit 12 is connected to 11. Further, the arithmetic processing device 1
A storage device 13 is connected to 2.

The movement amount data (coordinates) of the backup pin 6 is detected by the sensor 10 as an electric signal, which is converted into data by the data converter 11, and this data is transferred via the arithmetic processing unit 12 to the storage device 13 (for example, magnetic field). Disk device). At the time of reading, the data designated by the arithmetic processing unit 12 is read, and the data is converted by the data converter 11 to determine the drive of the backup pin 6.

The invention made by the present inventor has been specifically described above based on the embodiments, but the present invention is not limited to the embodiments and can be variously modified without departing from the scope of the invention. Needless to say.

The effects obtained by the typical ones of the inventions disclosed in the present application will be briefly described as follows.
It is as follows.

That is, a plurality of backup pins for restricting the position of the article to be handled, a plurality of arms capable of rotating the backup pins once in the horizontal direction, and a drive means for rotating and linearly moving each of the arms. Since a plurality of rails for guiding the linear movement of the arm are provided, the positioning of the article to be handled can be automatically set, and the backup pin for positioning the article can be automatically set in a short time. Can be done on a regular basis.
