Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention is applicable to parts used in parts assembly machines for example, electronic circuit boards, etc. This paper relates to an improvement of a storage device.

[Conventional technology]

FIG. 3 is a perspective view showing the main parts of a conventional suction and conveyance device for electronic components, as shown in Japanese Patent Publication No. 61-34955, for example. In FIG. 1, (1) is a printed circuit board;
(2) is a flat package IO to be transferred and attached to a predetermined position on this printed circuit board, (31 is a robot arm for positioning it, A vacuum suction device (4a) for suctioning electronic components is installed so as to be able to rotate and move up and down.

[Problem that the invention seeks to solve]

The vacuum suction and N device in conventional component suction and transfer devices is integrally installed on the robot main body arm as shown in 9 and above, so it is difficult to change the shape of the electronic components being handled.

The suction force and the shape of the suction surface cannot be changed in response to changes in size, so a single device can handle a wide variety of products.

There was a problem in that multi-shaped electronic components could not be handled.

The purpose of this invention is to solve the above-mentioned problems by making the vacuum suction device itself removable and replaceable so that electronic components of various types and shapes can be handled with one device. shall be.

[Means for solving problems]

In the case of this invention, a vacuum suction device (
4a) The above-mentioned vacuum suction device (51) which is provided in the exchange device (51) and which adsorbs electronic components between the pair of left and right gripping pieces (6a) and (6b) which move in opposite directions due to the operation of this conversion device A vacuum suction connection that removably clamps the device (4a) and automatically communicates with the component suction port (21a) at the tip when the vacuum suction device is fitted to one gripping piece (6a). A pipe (7) is provided so that the vacuum suction device (4a) is automatically communicated with the 6ζ vacuum source in the replaced state.

[Effect]

In the winding method of this invention, the distance between the left and right gripping pieces (6a) and (6b) changes depending on the movement of the gripping pieces (6a) and (6b). The component suction port of the device is automatically connected to the vacuum source when the device is installed.

[Metal practice]

An embodiment of the present invention will be described below with reference to the drawings. In other words, in Fig. 1 and Fig. 2, parts that are the same as or equivalent to those of the conventional one are given the same reference numerals, and repeated explanations thereof will be omitted. The exchange device (6a), (6b) is movably supported by the exchange device, and the vacuum adsorption device (4) of the present invention is movably supported by the exchange device.
a pair of left and right gripping pieces for gripping the outer casing (a) of (7);
- A circle 1llI-ζ of the force gripping piece (6a), a vacuum drawing connecting pipe (8
) are protrusions provided at two locations inside the gripping piece (6a) and have v-shaped grooves that serve as contact points when gripping the outer casing (a), and (9) has a similar effect. l A protrusion provided on the inside of the other gripping piece (6'b), US is a pipe connecting a vacuum source (not shown) and the vacuum connecting pipe (7), (141 is a vacuum connecting pipe) (
7), Tsuru is a compression spring that presses this vacuum connecting pipe (7), and 3υ is a vacuum suction device (4a).
) is fitted into the center of the outer casing (a) so as to be able to move up and down, and is used to vacuum-suction electronic components with the component suction port (21a) at its tip. It provides support when the component suction cylinder QD slides inside the outer casing (a) and prevents vacuum leakage, and the airtight chamber Q[
Q4 is a labyrinth fitting for forming the above-mentioned protrusion (9). ), the V-shaped groove provided on the outer periphery of (to) is the component absorbing tube Q
The fixing device that was previously installed and had its rotation stopper (to) planted, ■ is drilled into the outer casing (a) and the above-mentioned rotation stopper pin (
) is the sliding guide hole, @ is the outer casing (a) ζ, and ■
are vacuum ports opened at the other end of the component suction cylinder υ.

The operation of this invention will be explained below.

That is, FIG. 1 shows that each gripping piece (Sa
), (6t)), and the vacuum suction device (4a) is inserted between them and held between them. In this state, the protrusion (81
, (91 and V-shaped groove (2) Iζ, the vacuum suction device (4a
] The rotation and vertical movement of is restricted, and the whole is fixed at its position I.

At the same time as this fixation, the vacuum connecting pipe (7) is pressed against the vacuum outlet (to) on the outer periphery (a) by the spring force of the compression spring, to prevent vacuum leakage.
The sealed chamber tte in a) is communicated with the Makabe source via piping 4.

With the vacuum suction device (4a) fixed in the above state, a suction path is formed from the vacuum source to the tip component suction port (21a) of the component suction tube (21) as shown in FIG.

The electronic component (2) shown in FIG. 2 will be attracted to its tip. Note that when using another vacuum suction device equipped with a component suction tube with a different size and shape of the component suction port (21a), the same operation as above is performed, and the replacement of the vacuum suction device at that time requires opening between the respective gripping pieces. This can be done without any problem by adjusting the degree.

In the above embodiment, a device for suctioning and transporting electronic components onto an electronic circuit board or the like has been described, but the device to be suctioned and transported is not limited to the electronic component 1c.

〔Effect of the invention〕

Since the component and delivery device of the present invention is constructed as described above, various vacuum suction devices with different shapes and sizes of component suction ports can be used in one device, and the mounting state thereof can be adjusted. This has the effect that the component suction port can be automatically communicated with the vacuum source.
