Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to an electronic component transport/delivery mechanism for marking the product number, etc. after quality inspection of electronic components.

(b) Prior art and its problems Devices for marking the part numbers and names of electronic components have been known for a long time, but there is no device for holding small electronic components one by one and marking them at precise positions. It was empty.

The present invention makes this possible.

(c) Means for solving the problem The purpose of the present invention is as described above, and the structure of the present invention will be explained based on the structure of the embodiment shown in the attached drawings.

Component fitting recesses 22a, 22a, . . . are provided at regular intervals on the circumference of the continuously rotating receiving disk 22, and a suction air hole 22b and a claw protruding hole 22c are opened in the component fitting recess 22a, and the receiving disk 22 is rotated intermittently. After the component 2 pushed out and supplied from the intermittent supply device 3 to the component insertion recess 22a is fixed by suction through the suction air hole 22b, a position fixing claw 26 protrudes from the claw protrusion hole 22c.
It is configured to be moved to the end face of the component fitting recess 22a and positioned.

(d) Embodiment The purpose of the present invention is as described above.The structure of the present invention will be explained based on the structure of the embodiment shown in the attached drawings.

Fig. 1 is a drawing showing the overall configuration of the marking device, Fig. 2 is a front partial sectional view of the delivery device of the present invention, Fig. 3 is a plan partial sectional view, and Figs. FIG. 6 is a front view of the holding part showing the state, and FIG. 6 is an enlarged view of the positioning part.

The overall configuration will be explained with reference to FIG.

Reference numeral 1 denotes a parts feeder, which aligns parts 2, 2, etc. of electronic products such as resistors and capacitors one after another and feeds them one by one to an intermittent supply device 3, which rotates intermittently by 90 degrees. At each stop, the part 2 is received from below, and the part 2 is pushed out to the delivery roller device 4 of the present invention at a position rotated 90 degrees.

Delivery roller device 4 constituting the main part of the present invention
is in continuous rotation and is in contact with a transfer roller 5 on the other side, which is also in contact with a type roller 6 on the other side, and which is also in contact with an ink roller 7 on the other side.

The transfer roller 5, the type roller 6, and the ink roller 7 are continuously rotating, and when the type engraved on the type roller 6, such as the product number, comes into contact with the ink roller 7, ink is attached to it, and as it rotates, it comes into contact with the transfer roller 5. The ink of the type is transferred to the transfer roller 5, and printing is performed when the transfer roller 5 rotates and comes into contact with the part 2 of the delivery roller 4.

The printed part 2 is further rotated and delivered to the next process (for example, packaging, insertion into a board, etc.). However, the delivery position and arrangement to each roller can be changed depending on the plant.

The details of the delivery roller device 4 of the present invention are as follows.
It is illustrated in FIG.

The delivery roller device 4 is composed of a receiving disk 22, a mounting body 21, a position fixing claw 26, and the like.

As shown in FIGS. 2 and 3, a fixed disk 11, a support frame 16, and a detection device 1 are mounted on a base 10.
7 is fixed, and the fixed cam 1 of the fixed disk 11
2 is fixed with a bolt 13, and the fixed disk 1
1 is provided with a long hole 11a so that the position of the fixed cam 12 can be adjusted.

A rotating portion is fitted into the support frame 16 and fixed disk 11 via bearings 14 and 15.

In the rotating portion, a mounting body 21 is fitted onto a rotating shaft 20 that is continuously rotated, and a receiving disk 22 is fixed to the mounting body 21 with bolts 23.

A detection recess 21a corresponding to a fixing part to be described later is bored at a certain position around the front surface of the mounting body 21,
The tip of the shaft 30 of the detection device 17 fits into the detection recess 21a.

That is, in the detection device 17, a shaft 30 is fitted into a plate 31, a spring 34 is fitted onto the shaft 30 and biased toward the mounting body 21, and when the shaft 30 is fitted into the detection recess 21a, an intermittent In order to synchronize with the feeding operation of the feeding device 3,
It is detected whether the shaft 30 is fitted into a photocoupler 33 fixed to the plate 31 with bolts 32 and is blocking light.

A front clamping disc 24 and a rear clamping disc 25 are fixed to both front and rear sides of the receiving disc 22, and fixing portions A are arranged around the receiving disc 22 at regular intervals. The part 2 is supplied toward the fixed part A from the intermittent supply device 3 in the direction of arrow a in FIG.

That is, component fitting recesses 22a, 22a, . A storage hole 22d for the claw 26 is bored, and the position fixing claw 2 is inserted into the claw projection hole 22c and the storage hole 22d.
6 is placed.

The center portion of the position fixing claw 26 is pivotally supported by a pin 27 that is horizontally suspended between the receiving disk 22 and the front holding disk 24, and a roller 26 is provided on one side of the position fixing claw 26.
a is pivotally supported and abuts on the inside of the fixed cam 12. Also, a pin 2 is attached to the back end of the position fixing claw 26.
6b protrudes to lock a spring 29, and the other side of the spring 29 locks to a pin 25a protruding from the rear clamping disk 25, biasing the tip of the position fixing claw 26 in a direction. When the component 2 is fixed, the position fixing claw 26 and the inner wall of the claw protruding hole 22c of the receiving disk 22 are in contact with each other, and the position fixing claw 26 and the part 2 are in contact with each other.
As shown in FIG. 6, there is a gap l of 0.06 to 3 mm between the two parts to prevent damage during positioning of the parts.

(e) Effect of the invention In such a configuration, when the part 2 is supplied from the intermittent supply device 3 as shown by the arrow a in FIG. roller 26a comes into contact with it, and the fixing portion is opened as shown by the position fixing pawl 26' in FIG.

In this state, the supplied part 2 is sucked into the air hole 2.
2b, and as it rotates, the inner radius of the fixed cam 12 shown in FIG.

The component 2 supplied to the component insertion recess 22a is misaligned between the intermittent rotation of the intermittent supply device 3 and the continuous rotation of the delivery roller 4, so the position fixing pawl 26 rotates and the position shown in FIG. Then move it to a fixed position and correct it.

Thereafter, the part 2 is attracted by suction through the suction air hole 22b, and when it rotates in this state and comes into contact with the transfer roller 5, the part number etc. are printed on the part 5, and it is further rotated and conveyed to the next process. .

(f) Effects of the invention With the above-described configuration, the invention provides the following effects.

First, since each small part is guided and held by position fixing claws, it is now possible to determine the exact position, and there is no longer any misalignment of the printing of product numbers, etc. .

Second, the intermittent feeding device 3 needs to accurately obtain the parts 2 one by one from the parts feeder and feed them to the delivery roller 4, so in order to ensure accurate feeding, intermittent drive is required, and vice versa. Since the transfer roller 4 is a part that comes into contact with the transfer roller, the transfer ink accumulates therein, so it cannot be driven intermittently. Therefore, the delivery roller 4 needs to rotate continuously.

The handover of the parts 2 between the intermittent supply device 3 and the continuously driven delivery roller 4 is as follows:
There was a problem that the component insertion recess 22a was inconsistent, but this invention was able to solve this problem by having the position fixing claw 26 move to the end of the component insertion recess 22a and fix it. It is something.
