Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for tightening a sealing portion during assembly of electronic components such as capacitors.

Generally, electronic components such as capacitors are manufactured by inserting a capacitor element 22 equipped with a sealing plate 21 into a case 24 made of aluminum or the like together with an element fixing material 23, and then tightening the opening of the case 24 as shown in FIG. The roller 13 is tightened and sealed by a tightening device having a mechanism for rotating and pressing the roller 13.

In the conventional seaming device, a motor 25 is fixed to a frame 26 as shown in FIG.
By moving up and down, the rotating shaft 28 is moved up and down in a rotated state. As a result, the following problems arose.

(1) Since the rotating shaft 28 has a mechanism for rotation and vertical movement, the mechanism is complicated; (2) adjustment is difficult and dangerous; (3) parts wear out considerably; Accuracy after tightening is not achieved.

(5) Parts are expensive.

SUMMARY OF THE INVENTION The present invention aims to eliminate the above-mentioned drawbacks, and to provide a tightening device for electronic parts that has fewer failures and improves productivity.

The present invention will be described below with reference to an embodiment shown in FIG. FIG. 3 shows the main parts of a tightening device for electronic parts such as capacitors. A tightening roller 13 is set in a holder 14 connected to a rotating shaft 17, and the rotation of a motor 7 is rotated by a belt 6. It is transmitted to the shaft 17 and rotates. Reference numeral 15 denotes bearings, which are embedded in two locations above and below the slide block 16 to support the rotating shaft 17.

The vertical movement of the seaming roller 13 is performed by the vertical movement of the slide block 16 which is coupled to the drive slide plate 12 driven by the drive lever 9. The motor 7, which is fixed via a support 10 to a motor mounting plate 11 connected to the motor 7, also moves up and down accordingly.

The strut 10 to which the motor 7 is fixed can be adjusted with a guide hole formed in the motor mounting plate 11, and the tension of the belt 6 stretched between the pulleys 5 and 18 can be adjusted. be.

In order to transmit the movement of the drive slide plate 12 to the slide block 16, the drive slide plate 12 and the slide block 16 are connected by a female screw 20 provided on the connecting plate 4 and an adjusting male screw 2 that can be rotated through the female screw 20. By tightening the lock nut 3, the two are completely connected and can move up and down together.

The adjustment male screw 2 is made to rotate freely on the driving slide plate 12, and by rotating the hand crank 1, the height of the tightening roller 13, motor 7, etc. can be easily adjusted. The direction and pitch of the adjustment handle determine the direction of rotation and the amount of movement per rotation.
Also, the difference between the lowest position and the highest position, that is, the maximum adjustment range, is the slide block 16.
It is determined by the size of the guide plate 19 that guides the guide plate 19 and the frame 8 that holds the guide plate 19.
It can be arbitrarily determined as necessary.

As described above, the electronic component seaming device of the present invention is mechanically simplified, and compared to the conventional method, it is extremely easy to adjust the vertical movement and positioning of the seaming roller, and the accuracy is also improved. . In addition, parts can be easily and inexpensively replaced, the failure rate is reduced, productivity is significantly improved, and many other effects are achieved, which is of great industrial and practical value.
