Description

[Detailed Description of the Invention] [Field of Application of the Invention] When an electronic component of the present invention, particularly a dual in-line package (hereinafter simply abbreviated as DIP) component, is handled by a robot, it is possible to accurately position fL-female. This invention relates to a positioning device.

[Prior art]

Generally, a plurality of DIP parts are supplied on the market in the form of being housed in a stick, but when assembling or testing these parts, it is necessary to take them out one by one from the stick and then position them. However, as shown in FIGS. 1(a) and (b), the height 11I of one body 12 of the DIP component 1 is different from the height of the other body 12, and the shape of the lead pin 11 protruding from the body is different. Each body 12.1 with different
2, the mounting position L of the lead pin 11 on one end of each
ss and Ls are also different. Therefore, when attempting to position those DIP components under the same conditions, it is conceivable to position the lead pin 11 on one end using a positioning means such as a stopper, but in that case, the lead pin 11
Since the lead pin 11 is made of a spring material, when the lead pin 11 hits the positioning means, it bounces back due to its own elastic force, making it difficult to position it accurately.

[Purpose of the invention]

In view of the above circumstances, it is an object of the present invention to provide a positioning device for electronic components that is capable of accurately positioning even if the shape of the lead pin is different and even if the height of the electronic component body is different. It is.

[Summary of the Invention] In order to achieve the above object, the electronic component positioning device according to the present invention has a tilting chute that moves the electronic component while dropping it, and a lead pin on the tip side of the electronic component butts against it. a stopper disposed at the end of the inclined shooter; and a position correcting means for spraying compressed air onto the electronic component and suctioning it under vacuum; When the lead pin of the electronic component is previously placed on the shooter at a position where it hits the stopper and bounces off, the electronic component is turned into a stopper by blowing compressed air to the rear position of the electronic component that was bounced off by the stopper, and the electronic component is pushed against the stopper. The electronic component is characterized in that when the electronic component collides with the electronic component, the moving means moves onto the electronic component and vacuum-chucks the electronic component, thereby positioning the electronic component.

[Embodiments of the invention] The details of the present invention will be explained below with reference to FIG.

FIG. 2 shows an embodiment in which the electronic component positioning device according to the present invention is applied to a robot.

The electronic component positioning device according to the present invention includes a DIP component 1
The camera is equipped with an inclined shooter 2 that moves the camera to a predetermined position. The inclined shooter 2 extends from its one end 21 to its distal end 22.
The end part 22 is flat with an appropriate length and is lower than the one end part 21, so that it straddles the lead pins 11 provided on both sides of the DIP component 1 at the one end part 21. When placing DIP part 1,
The DIF component 1 is allowed to move while falling to the distal end 22 due to its weight.

As shown in FIGS. 1(a) and 1(b), the IP component 1 includes a main body 12 and both 111 in the longitudinal direction of the main body 12.
117- Consisting of a plurality of protruding lead pins 11, usually a plurality of lead pins are stored in the stick, and during assembly etc., they are taken out from the stick one by one by a take-out device (not shown) and sent to the inclined shooter 2. .

A DIP component 1 is attached to the distal end 22 of the inclined shooter 2.
A stopper 3 is attached to stop the movement of. The stopper 3 is provided protruding from both ends of the end portion 22 of the inclined shooter 2, and when the round DIP component 1 is moved, the lead pin 11 at the end of the stopper 3 abuts against the DIF.
It is now possible to stop the movement of parts.

Moreover, a position correction means 4 is provided on the inclined shooter 2 in order to accurately position the DIP component 1. The position correction means 4 is mounted on the robot and has a blowing mechanism that blows compressed air onto the DIP component and a suction mechanism that performs vacuum suction. The position correction means 4 moves the lead pin 1 of the DIP component 1 onto the inclined shooter 2 in advance.
1 hits the stopper 3 and is returned by the elastic force of the lead pin 11, the DIP to be returned is
It is placed at the rear position P8 of part 1. And D.I.
When F part 1 hits stopper 3 and is returned, DIP
The DIF component 1 can be accurately positioned by blowing compressed air onto the rear position P of the component using a blowing mechanism and by using the force of the compressed air to abut the DIF component 1 against the stopper 3. ing. Therefore, the blowing mechanism can blow compressed air so as to push the DIP component 1 against the stopper 3.

When the DIP component 1 abuts against the stopper 3, the flexible position correcting means 4 is moved laterally by a moving means (not shown) and moved downward to the DIF component surface position 8, and the DIP component 1 is moved by the suction mechanism. By vacuum suctioning the component 1, the mouth pot can handle the DIP component at an accurate position. Therefore, robots are provided with the function of the moving means through a teaching method or the like.

The electronic component positioning device according to the first invention has the above-mentioned configuration, and its operation will be described next.

The DIP parts 1 are taken out one by one from the stick by the take-out device, and are moved while dropping to the end portion 22 by the IQ inclined shooter 2. When the lead pin 11 at the tip of the DIP part 1 hits the stopper 3, Due to the elastic force of the lead pin 11, the DIP parts oblique shooter 2
The distal end 22 of is rolled back and stopped. At that time, the position correction means 4 is pre-arranged at the rear position n of the returned J)lP part 1, so that the compressed air can be transferred to the DIP part 1.
By spraying on the rear position of the DIP component 1, the DIP component 1 is moved and the lead pin 11 on the tip side thereof is brought into contact with the stopper 3. This allows accurate positioning of the J]P part 1. Therefore, even if the height of the DIP component main body 12 and the shape of the lead pin 11 are different, the DIP component can be reliably positioned by spraying compressed air.

Thereafter, the position correction means 4 is moved by the moving means to the DIF component surface position 8, and vacuum-chucks the DIP component 1. As a result, the robot equipped with the position correcting means 4 can reliably and easily handle the parts while maintaining the correct position.

〔Effect of the invention〕

As described above, according to the present invention, when the electronic component that has moved on the inclined shooter hits the stopper and is returned,
Since the positioning means is configured to blow compressed air and suck the electronic components, it is possible to accurately position the electronic components even if the height of the electronic component body and the shape of the lead pins are different. ,ru.
