The supply part of the pre-treatment system was installed in the above, and the receiving part of the post-treatment system was installed in the other of the dead points.

[0008]

According to the present invention, in the delivery device in the electronic component processing device, the structure is simple and the maintenance and inspection are easy, and the mechanism from the power source to the operation of the chucking device is the front stage. It can be freely arranged according to the installation position and structure of the processing equipment and post-processing equipment, and is extremely convenient for simultaneously delivering electronic components in multiple rows. Further, according to the present invention, the cam groove is formed in the cam plate which continuously rotates in one direction, and the cam follower is slid by the cam groove, so that the reciprocating operation time of the drive arm, the swing arm, etc. can be arbitrarily set. Since the value can be set, the operating efficiency can be improved and the transfer process can be performed in a short time.

That is, according to the present invention, when the chucking device is moved by the drive arm, the electronic parts and the like are moved during the forward movement of holding the fragile electronic parts and the like that are destroyed when firmly held.

The sandwiching operation of the chucking device 29 is controlled by the control device 30 by receiving a control signal from the timing signal generator 10. On the other hand, at the one limit position of the swing of the chucking device 29 with the swing of the swing arms 23, 23, the supply parts 32, 32 of the parts feeders 31, 31 as the pre-stage processing device are arranged. ing. That is, the parts feeders 31, 31 are installed on both sides of the apparatus having the above-mentioned configuration, and the electronic parts 33, 33, ..., Such as capacitors, are arranged and fed out from the respective parts feeders 31, 31.

The supply parts 32, 32 are provided on the base 37 with lead wires of the electronic parts 33, 33, .. It has guide plates 35, 35 facing each other at appropriate intervals so as to support the body from both sides. Further, stoppers 36, 36 are arranged on the guide grooves 34, 34 so that the two central chucking devices 29b, 29c can chuck the electronic components 33, 33, ....

On the base 37, the electronic components 33, 33, ... Are made to stand by to cause the chucking devices 29b, 29c to be chucked next, and the two chucking devices 29a, 29d on the left and right are chucked. In order to do so, air cylinders 38, 38 that also function as stoppers are provided. The guide plates 35, 35 are provided with notches 39 so that they can be chucked by the chucking devices 29.

Such as capacitors one by one and perform processing such as inspection, for example, one by one. Various types of conveyors or buckets can be applied.

The operation of the above-described configuration will be described below. 1 and 2, when the drive shaft 1 rotates, this rotation is transmitted to the rotary shaft 8 via the joint 2, the gear box 3 and the power transmission mechanism 7, and this rotation causes the rotary shaft 8 to rotate. Therefore, at this time, the electromagnetic clutch 9 is in the state where the rotating second pulley 6 and the rotating shaft 8 are connected. The electromagnetic clutch 9 disconnects the connection between the rotating second pulley 6 and the rotating shaft 8 when the electronic components 33, 33, ... Are hindered to be delivered to the post-processing device and stopped in an emergency. is there.

The rotation of the rotary shaft 8 rotates the cam plate 11, and the cam follower 13 is guided by the cam slot 12 of the cam plate 11, whereby the drive arm 14 swings.

In the one reciprocating operation of the drive arm 14, if the operation in one direction is set to high speed and the operation in the other direction is set to low speed, the time required for one reciprocating operation can be shortened, so that a fixed time is required. The difference in the number of operating steps in the above becomes extremely large. In other words, the rotation speed of the cam plate 11 can be increased. The swing of the drive arm 14 causes the first reciprocating rotating shaft 17 to reciprocate by a constant angle via the connecting rod 15 and the passive arm 16. Along with this, the swinging first pulleys 18, 18 also reciprocally rotate at a constant angle, and the swinging second pulleys 20, 20 are reciprocally rotated at a predetermined angle, for example, 180 degrees via the transmission belts 19, 19. Excuse me.

When the oscillating second pulleys 20 and 20 reciprocally rotate, the oscillating arms 23 and 23 oscillate together with the chucking device 29 within a certain angle range.

Are carried out from the cutouts 39 of the supply section 32, the piston rods of the air cylinders 38, 38 are contracted as shown in FIG. , And the electronic parts 33, 33, ... that are carried out next are released, and air is ejected from the air nozzles 41, 41 by opening a solenoid valve (not shown), and the electronic parts 33, 33 ,. 36, 36 is moved at high speed until it abuts.

In other words, between the position where the air cylinders 38 and 38 stand by to the position where the chucking devices 29b and 29c come into contact with the stoppers 36 and 36 that can be carried out, the space between the receiving portions 43 and 43 of the post-stage processing device is increased. One cycle in which the chucking devices 29b, 29c pass the electronic parts 33, 33, ... And then return to the supply parts 32, 32 at the moving speed by the excitation of the part feeders 31, 31 according to the distance. , Cannot reach the stoppers 36, 36 within the time required for the operation of the electronic parts 33, 33, ... With the jetting force of air from the air nozzles 41, 41, the electronic parts 33, 33 ,. It is designed to be transferred at high speed toward 36.
