Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an electronic component insertion device, and more particularly, to an electronic component insertion device that is configured to easily replace chucks with different jaws for inserting irregularly shaped electronic components. The present invention relates to a component insertion device.

[Background of the invention]

In a conventional electronic component insertion device, the chuck of the insertion head that grips the electronic component and moves it toward the printed circuit board grips a single-shaped component; therefore, the insertion capacity of the insertion device is limited. It was limited to a single component and was extremely low. Therefore, even if it becomes necessary to replace the chuck of the insertion head to match the electronic components, there is no chuck support means or chuck replacement means to easily replace the chuck, and chuck replacement takes time and productivity is low. There was a drawback. In other words, the conventional electronic component insertion device has a component supply unit that arranges and arranges a large number of identical electronic components on an immovable board, and a table that is movable in the X and Y directions. A board is placed on the printed circuit board, and an electronic component is gripped and conveyed from the component supply section and inserted into the inserted position of the printed circuit board. For this purpose, a chuck that grips electronic components,
A chuck support part that supports the chunk, and an insertion head having a mechanism for vertically moving these members and opening and closing the jaws of the chuck are movably attached via a running part. The traveling section is configured to be movable on the substrate in response to an electric signal. Therefore, as long as the electronic components remain on the board, the insertion work can be continued correctly by unattended operation. Furthermore, it is easy to detect that the component supply section is out of electronic components and replenish new electronic components so that the insertion work is not interrupted using known techniques.

However, since the chuck is designed exclusively for a single electronic component of the same shape, the chuck must be replaced manually to accommodate changes in the shape of the part due to changes in production plans or improvements. However, it required skill, labor, and time, and had the disadvantage of decreasing productivity.

[Purpose of the invention]

The purpose of the present invention is to solve the above-mentioned drawbacks of the prior art, and its purpose is to insert into a dedicated speed for irregularly shaped electronic components.
An object of the present invention is to provide an electronic component insertion device that automates chuck exchange.

[Summary of the invention]

In order to achieve the above object, the present invention arranges a plurality of chucks having irregularly shaped claws and the same locked portion on a chuck storage shelf, and the chuck storage shelf is moved below the chuck exchanging means, On the other hand, the chuck support means attached to the insertion head has a hook that can be freely engaged and detached from the locked part of the chuck, and the abutment part that is linked to this hook is linked to a cam, and the abutment part is connected to an external member. Each time the pushing and separating is repeated, the chuck exchanging means is sequentially positioned at a high position, that is, a position where the hook is locked on the locked part, and a low position, that is, a position where the hook is released from the locked part. The arms extending to sandwich the chuck support means engage or release the chuck by pushing and separating the abutting portion, and in response to a chuck exchange command, the insertion head is moved through the conveyance means. The used chuck is transported to the chuck exchanging means, and by the operation of the chuck exchanging means, the used chuck is detached from the chuck supporting means and stored in the empty position of the chuck storage shelf, and then the chuck is moved again after the chuck storage shelf is moved. The present invention is characterized by comprising a circuit for locking and mounting a chuck of a desired shape on the chuck supporting means by the operation of the chuck exchanging means.

Also, electronic components can be held close to each other. The chuck G1 for holding irregularly shaped electronic components has irregularly shaped claws 53a, but the dimensions of other members are set in common.

Other chuck G2. In G3, only the claws have a unique shape (see figure 1 of spear and figure 11 of fang).

Next, the chuck support member F will be explained.

Fig. 214 is a view of Fig. 2 when viewed in the direction of the arrow, and in Figs. Note cam 421 positioning bin 43. It consists of a support lever 45, etc.

The block 41 has a box shape with a downward opening, and the lower surface of one of the opposing side walls is a chuck flap.

The top surface of the lock 50 comes in contact with the block 50 (smoothly finished, and a positioning pin 43 is provided protrudingly). A tapered conical rod tip 61 faces the inner space of the block 50 so as to be able to move up and down, so that the rod 62 passes through the upper surface of the block 50.

On the side wall of the block 50 corresponding to the groove 51 of the chuck,
A support lever 45 is pivotally mounted via a pin 44. The support lever 45 extends in the vertical direction, and has a claw-like hook 4 at the lower end.

Further, one end of a hook lever 46 is engaged with the abutting portion 45b, and the other end of the hook lever 46 is engaged with a groove of the heart cam 42. The note cam 42 is carved into a plate and is fixed to a side wall of the block 41 perpendicular to the side wall on which the support lever 45 is attached. Details of the heart cam 42 are shown in FIGS. 5 to 7. That is, in these figures,
The heart cam 42 is made up of stepped grooves a, b, c, and d, forming a heart-shaped loop. When it is pushed and then separated, it is moved from position A to position B, and then returned from position B to position A by the pushing and separating action, and this operation is repeated. Therefore, the hook is when the lever tip 4.6a is at position A, and the abutting portion d5b.
If the position is called the high position, this position is the position where the hook 45a is locked in the chuck groove 51 as shown in Fig. The position is a low position, and this position is a position where the hook 45a is separated from the chuck groove 51.

Next, the chuck exchange means E and the chuck storage shelf H will be explained. Fang 8 figure not t, gll.

In the figure, a rail 12 is installed on a T-shaped base 10 via a rail holder 11 from one end to the other. The chuck storage shelf is bu V-)14. Positioning block 15. Guide 13. It consists of racks 19, etc. The plate 14 has approximately half the length of the rail 12 and is formed in a comb-like shape, and a positioning block 15 is fixed to the comb-like protrusion.

The positioning block 15 has four parts on the side facing the adjacent blocks, and a vertically movable receiving pin 16 that projects through the plate 14 from below faces the recessed part. The pin 16 of the receiver is given the habit of always protruding by an extensible spring 17. A guide 13 and a rack 19 are attached to the lower part of the plate 14, the guide 16 is loosely fitted on the rail 12, and the rack 19 is engaged with a binion 20. As shown by the two-dot chain line in Figure 8, there are six seats and five chucks G having irregularly shaped jaws are prepared. In the diagram, one empty seat is in use. The pinion 20 is fixed to the output shaft of a motor 21 driven by numerical control.

Therefore, after storing used chucks in empty seats, the chuck storage shelf H can be moved so that a desired chuck seat can be located at the position of the chuck exchanging means E. The chuck exchange means E includes a stud bolt 22. Upper play 1-23. Cylinder 24. Drive ring 26° fulcrum shaft 2B, ground 29. It consists of rollers 30 and the like.

A roller 30 is rotatably supported at one end via a pin 31, and a pin 32 having a spherical head is fitted into the other end. The approximately central portion of the arm 29 is located at the fulcrum shaft 2.
Since the roller 60 is fitted into the cylinder 8 and is swingable, and the roller 60 is engaged with the groove of the drive ring 26, when the rod 25 of the cylinder 24 protrudes, the arm 30 opens.
When the rod 25 is retracted, the arms 30 are narrowed so as to meet each other.

Next, the operation of this device will be explained.

When a chuck exchange command to replace the chuck G in use with another chuck G is issued, the chuck storage shelf H is moved by the drive of the motor 21 according to a circuit including an electric means (not shown), and the empty seat is replaced. Position it below the pair of arms 29 (see figure 8). On the other hand, in FIG. 11, the insertion head A moves close to the chuck exchanging means E by driving the running section C, and then lowers and seats the chuck G between the positioning blocks 150 by driving the motor 70. At this time, the receiving pin 16 is pushed down, so the receiving detects the movement of the lower end of the pin 16 and instructs the arm 29 to perform a pushing/separating operation. That is, as clearly shown in this figure, when the chuck G is seated, the abutment portion 45b of the chuck support means F is located at the same height as the arm 29 of the chuck exchange means E, so that it is not attached to the cylinder 24. rod 2
By performing the backward movement of 5, the pin 32 of the arm
pushes the abutting portion 45b, and as shown in FIG. 12,
The hook 45a is removed from the groove 51 of the chuck G. The arm 29 is then returned to its original position and separated from the abutting portion 45b, but the support lever 45 remains in a low position with the abutting portion 45b due to the action of the heart cam 420. The head rises and fang 13),
A new chuck G (not shown) is installed by moving the chuck storage shelf H.
is located below the arm 29. Then, when the insertion head descends and brings the chuck support member D into contact with the chuck G, the receiver causes the lower end of the pin 16 to move in a pushing and separating motion (see fangs 12 and q and 11). Then, the abutting portion 45b of the support lever 45 returns to the high position, and the hook 45a is engaged with the groove 51 of the chuck. After this, the insertion head rises again and moves between the component supply part B on the board and the printed circuit board 6 on the XY table D, and the operation of inserting the parts is repeated.

〔Effect of the invention〕

As is clear from the above description, the present invention has the advantage that chucks having different jaws can be easily replaced in order to insert irregularly shaped electronic components.
