Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a substrate positioning device S, and more specifically, a pin that fits into a pin hole formed in a substrate to position the substrate, and a support for this pin. Concerning the structure of the means.

(Prior Art) When printing circuit patterns, cream solder, etc. on a board using a screen printer, or when mounting electronic components on a board using a mounter, the board is precisely positioned.

Conventionally, such positioning of the board is generally performed by inserting a pin into a pin hole formed in the board.

(Problems to be Solved by the Invention) There are many different types of substrates, and the size of the via hole varies depending on the type of substrate, or there are some substrates that do not have a via hole and are positioned by other means. Therefore, when the type of board changes, the pins mentioned above must be replaced.

However, in the past, the pins were fixed to the support body with screws or the like, so it was extremely troublesome to replace the pins when changing the type of board. Furthermore, if the pins and the pin holes do not match in position and the pins fail to fit into the pin holes, the pins collide strongly with the substrate and are likely to damage the substrate.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a substrate positioning device that solves the problems of the conventional means described below.

(Means for Solving the Problems) The present invention comprises a pin and a support that supports the pin so as to be movable up and down and rotatable about its axis via a spring material, and a side surface of the upper end of the pin. A vertical notch is formed in the support body, and a plurality of engaging parts are formed at the upper and lower parts of the side surface different from this side surface, and the support body is removably engaged with the notch part and the engaging part. It is provided with an engaging member that does.

(Function) In the above configuration, when the engaging member is engaged with the vertically elongated notch, the pin is supported by the support body so as to be vertically movable by the spring force of the spring material. In this state, the board is positioned by fitting the pin into the pin hole. In addition, in this state, if the pin and the bottle hole do not match, the pin will collide with the board, but since the pin can move up and down and is supported by the spring material, the shock of this collision will be absorbed by the spring material ↓ The iron is absorbed.

Further, when the engaging member is engaged with the lower engaging portion, the pin is fixed to the support body. Further, when the pin is engaged with the upper engagement portion, the pin is housed in the support body.

Further, by separating the engaging member from the notch or the engaging portion, the pin can be easily removed from the support and replaced.

(Example) Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of the pin, and FIG. 2 is a side view of the substrate positioning device. As shown in FIG. 2, this positioning device consists of a pin 1 and a support 10 for the pin 1.

As shown in FIG. 1, the pin 1 consists of a cylindrical main body 2 and a small-diameter cylindrical leg 3 hanging vertically below the main body 2.

The upper surface of this pin 1 has an engagement groove 7 for engaging the dry nozzle.
is formed, and the side wall surface 8 at the upper end is chamfered into a tapered shape so that it can be easily fitted into a bottle hole (described later). A vertically long notch 4 is formed in the side surface of the main body 2. Furthermore, engaging portions 5a and 5b are formed on the upper and lower sides of the side surface different from the side surface where the notch portion 4 is formed.

A spring member 6 is attached to the leg portion 3.

In FIG. 2, the support 10 is made up of a cylindrical body 11 and a base 16 formed at the bottom thereof. Above pin 1
is supported within this cylindrical body 11 via a spring member 6 so as to be movable up and down and rotatable about its axis. Pin 1 is
A screwdriver is engaged with the engagement groove 7 and rotated.

An L-shaped engaging member 12 having spring properties is fixed to the side surface of the cylindrical body 11 with screws 13 . The distal end of this engaging member 12 is connected to the notch 4 and the engaging parts 5a, 5b.
removably engages with. A light emitting element 18 and a light receiving element 19 are arranged on the inner side surface of the base 16. The light emitting element 18 and the light receiving element 19 detect the lower end of the pin 1 when it is lowered. 20 is a substrate, and 21 is a bottle hole formed in the substrate 20.

This board positioning device has the above configuration,
Next, we will explain the handling operations.

In FIG. 2, the engaging member 12 is engaged with the notch 4. As shown in FIG. When the board 20, which has been conveyed to a container (not shown) and has arrived at two positions above the pins 1, is lowered, the pins 1 fit into the bottle holes 21, and the board 20 is positioned.

By the way, if the accuracy of the stopping position of the board 20 is poor or if a different type of board is mixed in by mistake, pin 1
There are cases where the bottle hole 21 and the bottle hole 21 do not match. In this case, the pin 1 collides with the substrate 20 (see FIG. 3), but the pin 1 is supported by the spring member 6 so as to be able to move up and down, and the engaging member 12 engages with the vertically long notch 4. Therefore, when pin 1 descends, the shock of this collision is absorbed by spring material 6,
The substrate 20 will not be damaged.

When the pin 1 is pressed down by the substrate Fi 20 and its lower end is detected by the light emitting element 18 and the light receiving element 19, a notification means such as a buzzer is activated to notify that the pin 1 has collided with the substrate 20. inform.

Further, some substrates do not have pin holes. In the case of such a board, the pin must be removed or stored, and if the pin is forgotten to be removed or stored, the pin 1 will collide with the board in the same way as described above. However, in this case as well, the pin 1 is supported by the spring member 6 so as to be able to move up and down, so it will not damage the board.
Also, the notification means can notify that fact.

By the way, some users may desire that pin 1 be firmly fixed. In this case, a screwdriver is engaged with the engagement groove 7 to rotate the pin 1 by 1806 degrees, and the engagement member 12 is engaged with the lower engagement portion 5b (the fourth
(see figure).

In this state, the pin 1 is firmly fixed so that it cannot move up and down.

FIG. 5 shows a case where a substrate 20 having no pin holes is positioned by means other than pins. In this case, since the pin 1 is not required, the pin 1 is pushed down, the engaging member 12 is engaged with the upper engaging portion 5a, and the pin 1 is stored below.

Further, when the pin 1 is taken out from the support body 10 in order to replace the pin 1, etc., the pin 1 is rotated and the engaging member 12 is removed from the notch 4, the engaging part 5a, and the like, as shown in FIG. 5b and brought into contact with the side surface of the main body 2. In this state, pin 1
can be pulled out from the support body 10 without difficulty, and the pin 1 can be easily replaced in response to a change in the type of board 20.

(Effects of the Invention) As explained above, the present invention includes a pin and a support that supports the pin so as to be movable up and down and rotatable about its axis via a spring material, and the upper end of the pin is A longitudinal notch is formed on a side surface, and a plurality of engaging portions are formed at the upper and lower portions of the side surface different from this side surface, and the supporting body is removably engaged with the notch portion and the engaging portion. Since the board positioning device is configured by providing a mating engaging member,
By selectively fixing the pins to the support body, storing them, and supporting them so as to be able to move up and down, it is possible to cope with the positioning of various types of substrates, and it is also possible to easily replace the pins.
