Abstract

PURPOSE:To make it possible to easily and certainly position various types of large and small articles in simple structure without deforming them by holding a sliding plate having abutting sections at a specified degree with an article placed thereon and vibrating the sliding plate for sliding the article so that an article may be positioned with two sides or more of it abutted to the abutting sections. CONSTITUTION:The article 20 in a tray is moved to a position above the sliding plate 10 of a positioning device by a transporter 17. At the same time, an actuator 14 is raised by a hydraulic cylinder 13 and rotates the plate 10 centering a shaft 9 and stops with the plate 10 slanted to place the article 20 on the plate 10. In the next step, the plate 10 connected to a base plate 2 is vibrated by an air vibrator 15. By this vibration, the article 20 made to slide in the arrow mark direction on the plate 10 and stops when two sides of the article 20 is abutted to the abutting sections 7a and 8a of the arms 7 and 8 of a positioning device 5 to be positioned. Then, after completing positioning the vibrator 15 is stopped, and the article 20 is adsorbed through a vacuum hole 11 to be fixed to the position, and the actuator 14 is lowered to return the plate 10 to the original position.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a positioning device for parts such as, for example, a conductor device.

[Prior Art] For example, when a semiconductor device placed in a tray is mounted on a printed wiring board, the semiconductor device in the tray is transported to a positioning device by a transporter. The semiconductor device is transported to a predetermined position on the printed wiring board and lowered in that state, each outer lead of the semiconductor device is aligned with the terminal provided on the printed wiring board, and soldering and the like are performed.

In this case, when the ``1'' conductor device is lowered onto the printed wiring board, it is desirable that the aratterer leads and terminals be aligned as they are, and that soldering etc. can be performed immediately without any modification. .

FIG. 5 is an explanatory diagram showing an example of a conventional positioning device. In the figure, 21 is a fixed member, 22 is a sliding member, and at opposing positions, for example, a right-angled isosceles pentagonal cutout 23.
24 are respectively provided, and when the sliding member 22 is moved in the direction of the arrow and brought into contact with the fixed part [21], a square space is formed.

In order to position the component 20 using the above-mentioned device,
The sliding member 22 is moved backward to lower the component between the two members 21 and 22, and the sliding member 22 is moved forward. As a result, the component 20 is pushed into the cutout 23 of the fixing member 21, and the two sides of the component 20 abut 17 on the two sides of the fixing member 21, thereby positioning the component 20.

FIG. 6 shows another example of a conventional positioning device, in which a recess 26 is provided on the upper surface of a block-shaped member 24 to match the shape and size of the component 20 to be positioned.
The part 20 carried by the transporter is placed in this recess 2.
6 and positioned.

[Problems to be Solved by the Invention] The conventional positioning devices described above are not versatile because the jig must be replaced each time the size or shape of the part to be positioned changes, making the work cumbersome. Not only that, but also a large number of jigs must be prepared, which increases the cost for manufacturing and managing them.

Furthermore, in the example shown in Fig. 5, the parts are sandwiched between the fixed member and the sliding member for positioning, so there is a risk that the parts may be deformed. The problem has become a major obstacle.

Furthermore, if accurate positioning cannot be achieved using the above-mentioned devices, positioning must be performed using an image recognition device, which is not only cumbersome but also
A large amount of equipment cost is required. .

The present invention has been made to solve the above problems, and provides a positioning device that has a simple structure, can easily and accurately position various parts of different sizes and shapes, and is free from the risk of deforming the parts. It is intended to obtain.

[Means for Solving the Problems] A positioning device according to the present invention includes a sliding plate having a contact portion with which at least two sides of a component to be positioned abut, and which is pivoted to a substrate in the vicinity of the contact portion; It consists of a drive mechanism that rotates this sliding plate around an axis and holds it at a predetermined angle, and a vibration generating mechanism that applies vibration to the sliding plate.

[Operation] The drive mechanism rotates the sliding plate and stops it in an inclined state. Next, the component is placed on the sliding plate, and the vibration generating mechanism is activated to vibrate the sliding plate. As a result, the part slides down on the sliding plate, and the two sides of the part come into contact with the abutting portion, stopping and positioning the part.

Once the positioning is complete, the vibration stops and the sliding plate returns to its original position.

[Example] Figure 1 is a front view schematically showing an example of the present invention, and Figure 2 is a front view schematically showing an example of the present invention.
The figure is a plan view thereof. In both figures, 1 is a base, 2 is a board fixed on a column 3 erected on the base 1, and 4 is a support member fixed to a corner of the board 2. Reference numeral 5 denotes a positioning member having a Y-shaped plane, and the leg portion 6 is rotatably supported by the support member 4 via a shaft 9. For example, the arm portions 7 and 8, which are opened to 45", have sliding plates 10. The corner of is fixed and the sliding plate 1
Between the upper surface of 0 and the inner edges of the arms 7 and 8, there is a contact part 7a.
, 8a are formed. Reference numeral 11 denotes a vacuum hole provided at a corner of the sliding plate 10, which is connected to a vacuum source (not shown).

Reference numeral 12 denotes a spring interposed between the sliding plate IO and the support column 3 (or the base plate 2), which constantly applies a rotational force to the sliding plate 10 in the direction of arrow a about the shaft 9. 13 is a hydraulic cylinder (or air cylinder) installed on the base 1, 15 is the base 1
With the air-by-break installed above, its vibrator 16
is connected to the substrate 2.

Next, the present invention will be explained in detail with reference to FIGS. 3 and 4. First, the transporter 17 transports the component 20 in the L-ray to the top of the sliding plate 10 of the positioning device. At the same time, the hydraulic cylinder 13 is actuated to raise the actuator 14, the sliding plate IO is rotated around the shaft 9 and stopped in an inclined state (approximately 30 degrees in the embodiment), and the component 20 is placed on the sliding plate 10. rain down

Next, the air vibrator 15 is activated to vibrate the substrate 2, and therefore the sliding plate 10 connected thereto, as shown in FIG. As a result, the component 20 slides on the sliding plate 10 in the direction of the arrow, and the two sides of the component 20 come into contact with the contact portions 7a and 8a of the arms 7 and 8 of the positioning member 5, stopping and positioning. .

When the positioning is completed, the air-by-break 15 is stopped, the part 20 is sucked through the vacuum hole 11 and fixed in that position, and the actuator 4 of the hydraulic cylinder 13 is lowered to return the sliding plate 10 to its original position. .

Then, the component 20 is transported by the transporter 17 to, for example, a printed wiring board and lowered to a predetermined position.

At this time, the component 20 is accurately positioned, so if the component 20 is, for example, a cliff conductor device, the outer = I is almost aligned with the terminal of the printed wiring board (viscosity ± 504), soldering can be carried out without making any major repairs.

In addition, when polishing the surface of the sliding plate 10, polishing is performed in the direction of the arrow in FIG. 4, that is, in the direction in which the component 20 easily slides. Also, place this device on an X-Y table or rotating table.
, I, so that the position of the device itself can be adjusted.
