Abstract

PURPOSE:To obtain an electronic part transfer device where the transfer face on the side of a chute does not abrade and the electrode component side does not flaw either by providing a cam follower at the free end of a lever thereby floating up an electronic component from the transfer face while it is sent after a chuck catches the electronic component. CONSTITUTION:A capacitor 1 placed on a transfer path 4 is caught by a chuck 6, and by rotation of an eccentric cam 23, a lever 21 rocks downward, and rocking shaft 18 rotates by a specified angle. With this, a rocking base 19 also rotates, and the capacitor 1 caught by the chuck 6 floats up from chute plates 2 and 3 being transfer faces. In this condition, the rocking base 19 rocks along the rocking shaft 18 by means of a cam mechanism, and the capacitor 1 caught by the chuck 6 is placed on the chute plates 2 and 3 being the transfer faces. Hereby, the capacitor 1 caught by the chuck 6 can be transferred without sliding on the chute plates 2 and 3.

This device is composed of a capacitor supply device, a capacitor delivery device, a conveyance device, a taping device, and a punching device. Among these devices, the conveying device intermittently sends out the capacitor 1 from the inlet to the outlet along the conveying path, as shown in FIG.
In the work area during this time, necessary processing and inspection work is applied to the capacitor 1, and the capacitor 1 is sent to the next taping section.

This conveyance device is installed horizontally and has two elongated chute plates 2.3, and a conveyance path 4 is formed between these chute plates 2.3. This conveyance passage 4 is located on an extension of the lead-out passage (not shown) of the capacitor supply device, and the width of this conveyance passage 4 is larger than the diameter of the lead wire so that the lead wire of the capacitor 1 can pass through. The capacitor 1 is also made slightly larger and has dimensions such that the main body of the capacitor 1 can be held by the edge of the chute plate 2.3. Incidentally, the capacitor 1 delivered to the transport device by the capacitor delivery device is preset so that its lead wire falls into the transport path 4 and the capacitor 1 body can slide on the chute plate 2.3. .

A carriage 5 is disposed on one side of the chute plate 3, and a plurality of chucks 6 are disposed at equal intervals near the inner edge of the carriage 5. The number of these chucks 6 may be appropriately determined as required.

The mechanism for imparting such movement to the carriage 5 consists of a combination mechanism of a mechanism for moving the carriage 5 in the direction of the arrow (■) and a mechanism for moving the carriage 5 in the direction of the arrow (■). Of these, look at carriage 5■■
The mechanism for moving in the direction is a cam groove 8a on the side surface of the drive shaft 7.
It is composed of a cam disk 8 provided with a cam groove 8a and a connecting rod 9 that is engaged with one end of the cam groove 8a of the cam disk 8. When the cam disk 8 is rotated, the carriage 5 is connected to the carriage 5 via the connecting rod 9. is moved in the direction of arrow ■ or arrow ■. On the other hand, the mechanism for moving the carriage 5 in the direction of the arrow ■ or the arrow ■ consists of an arm 12 whose one end is supported by a pivot shaft 10 and whose intermediate portion is engaged with the cam groove 1↓a of the cylindrical cam 11 via a slider. The tip of the arm 12 is connected to the carriage 5 via a bottle 13. When the cylindrical cam 11 rotates, the arm 12 moves the carriage 5 in the direction of the arrow (2) or (2) via the pin 13 at its free end.

Such movement of the chuck 6 is performed so that each chuck 6 draws a rectangular loop, and furthermore, the stroke in the longitudinal direction of the rectangular loop is preliminarily applied to adjacent chucks 6.6.
The interval is set in advance to be equal to the interval of . Therefore, the capacitors 1 placed in the transport path 4 are gripped by the chuck 6 and relayed one after another, and are sent along the transport path 4 from the entrance to the exit.

Processing or inspection required for the capacitor 1 while the capacitor 1 is relayed to the adjacent chuck 6, such as forming a clinch on the lead wire of the capacitor 1, detecting the polarity of the capacitor 1, and detecting the polarity of the capacitor 1. Various necessary operations are performed, such as inverting the capacitor 1 to align the capacitors 1, removing defective capacitors 1, and cutting the lead wires of the capacitor 1 to predetermined lengths to align them.

In addition, the reference numeral 14 in the figure is a piston cylinder, and this piston cylinder 14 moves the operating rod 15 by a predetermined stroke, moves one of a set of claw plates that constitute the chuck 6, and moves the chuck via gears 16a and 16b. 6 claws are opened and closed.

[Problem to be solved by the invention]

However, when a capacitor is transported using the above-mentioned transport device, the capacitor slides on the chute plate while being in contact with the chute plate.
Another problem is that the bottom surface of the capacitor may be damaged.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an electronic component transport device that can transport electronic components without causing wear on the transport surface on the chute plate side and without damaging the electronic components.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a plurality of chucks capable of holding electronic components on a carriage, and transports the electronic components on a chute plate by moving the carriage back and forth and left and right under a certain cycle. In an electronic component transport device configured to feed electronic components along a passage, the chuck is mounted on the carriage, and the chuck is mounted on a rocking table whose one end is attached to a rocking shaft having an axis substantially parallel to the transport passage. A lever is cantilevered at the end of the swing shaft, and a cam follower is provided at the free end of the lever. When the cam follower and the eccentric cam are engaged, the chuck picks up the electronic component. The device is characterized in that the electronic components are lifted off the conveyance surface while being held and conveyed.

[For production]

With the chuck mounted on the rocking table clamping one of the electronic components on the sudo plate, the lever is rocked by an eccentric cam, and the rocking shaft fixed to this lever is rotated by a predetermined angle. The oscillating table tilts accordingly, allowing the electronic component held by the chuck to rise above the conveyance surface, and while maintaining this state, the electronic component is conveyed downstream. .

〔Example〕

An embodiment of the present invention will be described below with reference to FIG.

The conveying device according to the present invention shown in FIG. 1 has two elongated chute plates 2.3 installed horizontally,
A conveying path 4 is formed between these chute plates 2.3. A carriage 5 is arranged on one side of the chute plate 3. Bearing brackets 17 are provided at both ends of the carriage 5, and a swing shaft 18 is rotatably supported on the bearing brackets 17. This swing shaft 18 is substantially parallel to the conveyance path 4. A swing table 19 is mounted on the swing shaft 18 . Furthermore, a chuck 6 is provided on the upper surface of the swing table 19 via a chuck mounting portion 20 .

On the other hand, a lever 21 is cantilevered at the end of the swing shaft 18 . A cam follower 22 is provided at the free end of this lever 21, and an eccentric cam 23 that engages with this cam follower 22 is fixed to a drive shaft 24.

It should be noted that the carriage 5 is movable in the directions shown by the arrow (2) and (2). Further, the rocking table 19 is movable in the directions of arrow (2) and (2). These drives were developed using the
It is driven by a cam mechanism as known from No. 48.

The conveying device in this embodiment configured as described above is as follows:
It works as follows.

First, the carriage 5 is moved in the direction of arrow (2) by a cam mechanism (not shown). Therefore, the capacitor 1 placed on the transport path 4 is clamped by the chuck 6.

Thereafter, due to the rotation of the eccentric cam 23, the lever 21 swings downward, and the swing shaft 18 rotates by a predetermined angle. Along with this, the rocking table 19 also rotates, and the capacitor 1 held by the chuck 6 floats upward from the chute plate 2.3, which is the transport surface (arrow view ■). In this state, the rocking table 19 is driven along the rocking shaft 18 by a cam mechanism (not shown), and the capacitor 1 held by the chuck 6 moves in the direction of arrow (2). Therefore, due to the rotation of the eccentric cam 23,
The lever 21 swings upward, and the swing shaft 18 rotates by a predetermined angle. Along with this, the rocking table 19 also rotates, and the capacitor 1 held by the chuck 6 is placed on the chute plate 2.3, which is a transport surface (arrow view ■). At this point, the chuck 6 is opened. Next, the carriage 5 moves in the direction of the arrow (2). Further, the rocking table 19 moves in the direction of the arrow (2).

In this way, by operating the conveying device, the capacitor 1 held by the chuck 6 is transferred to the chute plate 2.3.
Since the capacitor 1 can be transported without slipping on the top, the upper surface of the unit plate 2.3 will not be worn, and the bottom surface of the capacitor 1 will not be damaged.

〔Effect of the invention〕

With the above-described configuration, the present invention prevents the electronic components from slipping on the chute plate when the electronic components are transported, so that the transport surface on the chute plate side does not wear out, and moreover, the electronic components do not slide on the chute plate. It also has the effect of not causing scratches.
