Description

[Detailed Description of the Invention] The present invention is used for taping, printing, etc. to align the polarity of axial type (double lead type) diodes, capacitors, light emitting diodes, etc., which have + and - polarities. It is something.
As shown in Fig. 1, this type of general-purpose aligning machine measures the polarity of electrical components 2 on a chain conveyor (index) 1 using a measuring plate 3. If the polarities are not aligned, the electrical components are placed at the next position. After both lead wires 2 and 2' of 2 are pushed up by a forked push-up lever 4 and rotated 180 degrees, the electrical component 2 is lowered onto a conveyor and transferred to the next process. Therefore, the conveyor 1 must be stopped while the push-up rod 4 is in operation, which slows down the transfer speed accordingly.
Furthermore, if the vertical movement or rotational speed of the push-up lever 4 is increased, there is a risk that the electrical components on the push-up lever 4 will fall, so the speed cannot be increased very much.

As a result, the transfer capacity of general-purpose machines is only about 120 to 150 pieces per minute.

The present invention was researched to eliminate the drawbacks of such general-purpose machines, and improves the transfer capacity by continuously reversing polarity while determining uneven polarity, thereby improving printing, drying, and taping processes in subsequent processes. The aim is to make full use of the processing capabilities of such mechanisms and speed up the alignment of electrical components.

The present invention is constructed as described above, and in order to use it, first, the rotating part 11 is rotated, the vibrator 15 is vibrated, and the electrical parts are placed in the supply part 10 in an irregular state.

Next, when the inspection plates 35 and 35 come into contact with a and a' of the electric component A at the measuring section 12, if the polarity of the electric component A is not aligned, the measuring device 45 is energized and the correction section 13 is removed after a certain period of time. When the electric component A is activated, the correction claw 36
When the correcting claw 36 reaches the tip position, the motor 37 connected to the measuring device 45 rotates, the rotating shaft 38 rotates by a predetermined angle, and the tip of the correcting claw 36 is located inside one of the lead wires a. Thus, one lead wire a is lifted along the upper edge of the straightening claw 36 and at the same time the straightening claw 36
is restored (if there are consecutive irregularities in polarity, the correction claw remains rotated). As the gripping pieces 23 and 24 rotate laterally, and as the rotation of the rotary disk 20 progresses, the lead wires are lifted up by the reversing plate 4 in the reversing section 14 as shown in FIG.
