Abstract

PURPOSE:To prevent the damage of parts by installing delivery/stocking roller conveyors in parallel at both sides in a direction of diameter of a reversing roller having a plurality of disks placed at prescribed intervals which have radial notches so as to receive and deliver works between the notches and both conveyors in the titled device such as an IC frame. CONSTITUTION:A work 10 is fed to a X direction by a stocking roller conveyor 20 and stopped by a stopper 32. Then, stocking and feeding claws 28 are lifted, the work 10 is raised from rollers 22, moved to a notch 16 and caused to enter the notch 16. Then, the work 10 is lowered, retracted and delivered to the notch 16. Subsequently, a rotor 12 is rotated and the work 10 is conveyed into the next notch 16. The work 10 in the notch 16 aligned with a delivery conveyor 24 is moved and mounted on the delivery conveyor 24 by means of feeding claws 30. According to this constitution, the damage of parts can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a reversing conveyance device for reversing electrical components such as IC frames. (Background of the Invention) In the manufacturing process of ICs (integrated circuits), it may be necessary to invert the IC frame and perform various processing on it. Bond multiple IC boards to
Since the parts are sealed with resin, and the frame itself is a very thin metal plate, there is a problem that it is easily damaged during transportation. In addition, it is necessary to remove the dust generated when this IC frame is resin-sealed, and for this purpose, the workpiece (I
Conventionally, it has been considered to apply a jet stream of cleaning liquid to the C frame). In this case, if only the cleaning liquid is to be injected onto the workpiece, it is sufficient to apply the jet stream from the upper and lower surfaces of the workpiece, so there is little need to turn the workpiece over. However, due to recent advances in IC package molding resin technology, which has improved the adhesion of molding resins, deburring may not be possible with a simple high-pressure jet of cleaning fluid. Therefore, the applicant proposed a method in which the IC frame is submerged in a slurry containing abrasive materials such as glass beads and a cleaning liquid, and a high-pressure jet of the cleaning liquid is applied from above. However, in this case, the jet stream can only be sprayed onto the workpiece from above, so the workpiece must be turned over. (Object of the invention) The present invention was made in view of the above circumstances, and
The purpose of the present invention is to provide a reversing conveyance device that can reverse electrical components such as C-frames without damaging them. (Structure of the Invention) According to the present invention, the object is to provide a rotor that holds a plurality of discs having substantially radial cuts at a predetermined interval, and a conveyor that is located on one side of the rotor and that transports a workpiece to the rotor shaft. a roller conveyor, an unloading roller conveyor located on the other side of the rotor that unloads the workpiece in the rotor axial direction, and an unloading roller conveyor that is located between each roller of the loading roller conveyor and transports the workpieces on these rollers to the notch of the rotor. This is achieved by a reversing conveyance device characterized in that it is provided with an unloading feed claw located between each roller of the unloading roller conveyor for transferring the workpiece in the notch of the rotor onto these rollers. (Embodiment) Fig. 1 is a perspective view of an embodiment of the present invention, and Figs. 2A to 2E are explanatory diagrams of its operation. Reference numeral 10 in the figure is an IC frame as a workpiece, which is made by bonding an IC board to a thin metal plate as described above and sealing the IC board with resin. Reference numeral 12 denotes a rotor, in which a plurality of (for example, four) disks 14 are coaxially fixed at predetermined intervals. A plurality of notches 16 (for example, six places) are formed in these circular plates 14 at equal intervals (for example, every 60 degrees) in a substantially radial direction, and the notches 16 of each disc 14 are formed in the rotation axis 1 of the rake l2.
8 are fixed to the rotating shaft 18 so as to overlap when viewed from a direction parallel to the rotating shaft 18. This rotor l2 is connected to the feed pawls 28 and 30 described later.
It rotates intermittently at every angle of cut 16 (60°) in synchronization with. Reference numeral 20 denotes a carry-in roller conveyor, which is disposed on one side of the rotor 12 and carries the work lO in the direction of the rotation axis 18 of the rotor 12. That is, this roller conveyor 20 includes four rollers 22 corresponding to each disk l4, and these rollers 22 rotate in the same direction around an axis perpendicular to the rotation axis l8 of the rotor 12. Reference numeral 24 denotes a carry-out roller conveyor, which is disposed on the other side of the rotor 12 and carries out the workpiece 10 in the 18° direction of the rotation axis of the rotor l2. That is, this roller conveyor 24 includes four rollers 26 corresponding to each disk 14, and these rollers 26 rotate in the same direction around an axis perpendicular to the rotor rotation axis l8. Reference numeral 28 denotes three carry-in feed claws, which are arranged between each roller 22 of the carry-in roller conveyor 20. These feed claws 28 move from the base point A in the order of B, C, D, and A as shown in FIG. 2A, and move the workpiece 10 carried onto the roller 22 to the notch 16 of the rotor l2. 30 is three unloading feed claws, and the unloading roller conveyor 2

, d, and a to move the workpiece 10 in the notch 16 of the rotor l2 onto the roller 26. Note that the carry-in roller conveyor 20 is provided with a stopper 32 that stops the workpiece 10 at a predetermined position. This device operates as follows. First, the upper surface of the workpiece 10 is deburred in a pretreatment step (not shown), for example, in a deburring step, and then carried onto the roller conveyor 20 from the X direction in FIG. 1 by another conveyor. Each roller 2
2 rotates in the same direction and sends this work 10 in the X direction,
When a sensor (not shown) detects the workpiece 10 that has stopped against the stopper 32, the carry-in feed claw 28 moves up from base point A in FIG. 2A to point B and moves the workpiece 10 onto the rollers as shown in FIG. 2B. Lift it up from 22. The feed pawl 28 then moves from point B to point C, inserts the workpiece 10 into the notch 16 of the rotor 12, and then descends to point D, resulting in the state shown in FIG. 2C. While the feed pawl 28 returns to the base point A, the rotor l
2 rotates by a certain angle (60°). By repeating the above operation, the work lO is sequentially carried into each cut l6.

On the other hand, the carry-out feed claw 30 sequentially transfers the work lO, which has been inverted by the rotation of the rake 12, onto the carry-out roller conveyor 24. That is, when the work lO is sent by the rotor 12 to a position facing the roller 26, the feed claw 30 moves from its base point a to b. Move to point e, support the work lO from below and raise it (Fig. 2D). The feed claw 30 then moves from point C to points d and a in order to place the work lO on the roller 26. Each roller 26 rotates in the same direction to send out the work lO in the y direction of FIG. 1, and the work lO is sent to the next processing step, for example, a deburring step, by another delivery conveyor (not shown). (Effects of the Invention) The present invention As described above, the work carried in by the carry-in roller conveyor is lifted by the feed claw and placed in the notch of the rotor, and as the rotor rotates, 4. After the workpiece is reversed, the workpiece is taken out by another feed claw, placed on a carryout roller conveyor, and carried out, so that the workpiece can be reversed without damaging it. Therefore, it is suitable for reversing easily damaged electronic parts such as IC frames.
