Abstract

PURPOSE:To prevent a slippage of parts and to transfer the parts easily and reliably by positioning the parts with a block and adsorbing the parts to a magnet to be turned and transferred in a unit for turning and transferring parts such as a push-switch or the like. CONSTITUTION:Both ends of a transported part 2 are supported by a support portion of a positioning projection 33 of an escape block 14, and the part is brought into contact with a retaining projection 34 of the escape block 14 to be stopped. When the part is detected by a detector 35, a motor is started, so that a positioning lever 27 is turned to adsorb the part 2 with magnets 25, 26. Subsequently, the escape block 14 is moved in the same manner in co-operation with an adjust screw 36. Thus, the part 2 is completely positioned to be vertical and delivered to a chuck. In this arrangement, the part can be transferred easily and reliably without slippage.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a component transfer device that changes the direction of a component such as a push switch and transfers the component.

2. Description of the Related Art Conventional Structures and Problems Conventionally, in the manufacturing process of various electronic parts and devices, it has been necessary to change the direction of parts frequently in order to automate manufacturing. Therefore, in the past, a part of the part was sucked up by a suction part by vacuum suction or grabbed by a chuck part, and the suction part or the chuck part changed direction, changed the direction of the part, and picked up the part that had changed direction. The suction unit or chuck unit in the next process receives the parts and supplies them to the next process.

However, this configuration requires a suction device such as a compressor for the suction section or a drive device for the chuck section, resulting in a complicated structure.

OBJECTS OF THE INVENTION In view of the above-mentioned drawbacks, the present invention relates to a component transfer device that has a simple configuration and changes the direction of components without positional deviation.

Structure of the Invention In order to achieve the above-mentioned object, the present invention provides a converting section provided with a lever that holds and changes the direction of a component positioned by a block using a magnet, and a component whose direction has been changed by the converting section is transferred. The configuration consists of a transfer section.

Since the parts are positioned by the block and then held by the lever, there is no misalignment of the parts, and since the parts are held by the lever's magnet, a very simple structure can be achieved.

DESCRIPTION OF EMBODIMENTS A component transfer device according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of a parts transfer device according to an embodiment of the present invention, and FIG. 2 is a plan view thereof.

As shown in the figure, this embodiment includes a converting section 3 that changes the direction of the component 2 supplied from the previous process 1, and a transfer section 5 that transfers the component 2 whose direction has been changed by the converting section 3 to the next process 4. It is composed of a conversion section 3 and a fixing base 6 for fixing the transfer section 5.

The conversion section 3 includes a plate-shaped holding stand vertically attached to a fixed stand 6, and a conveyor provided on one side of the holding stand 7 for carrying the parts 2 sent from the previous process 1 via the connecting section 8. 9, a motor 12 provided on the other surface of the holding table 7 by an L-shaped bracket 10 and operating the conveyor 9 via gears 11a and 11b, and a motor 13 provided perpendicularly on the other surface of the holding table 7. A rotating escape block 14 is provided.

In the transfer section 5, a movable section 18, which has a chuck 16 at its tip and a gear 17a below, is rotatably attached to a support base 15 fixed to a fixed base 6. The movable part 18 is fixed to the support base 15, and has a gear 17 at its tip.
The chuck 16 of the rotating part 18 reciprocates between the escape block 14 of the converting part 3 and the front end of the next step 4 by rotating by a motor 19 having a gear 17b meshing with the rotating part 18.

Next, the configuration near the escape block 14 is shown in Figures 3 and 4.
This will be explained using figures.

As shown in the figure, one of the blocks has a rotation shaft 20 into which a motor 13 and an escape block 14 are rotatably inserted.
It is mounted so that the receiving bearing 21 is parallel to the bearing 21. The motor 13 and the shaft 20 are connected by a gear 22 attached to the motor 13 and a gear 24 attached to the shaft 20 with a nut 23.

The escape block 14 has a fan shape, and a recess 28 in which a positioning lever 27 having two magnets 25 and 26 on the upper surface is rotatably inserted is provided in the upper center thereof in parallel with the holding base 7. . The escape block 14 has a shaft 2
0 is inserted in a rotatable state, but the positioning lever 27 is configured to sandwich the shaft 20 with a fixing screw 29,
It rotates due to the movement of the shaft 20. A compression spring 30 is installed between the lower part of the positioning lever 27 and the bottom of the recess 28 of the escape block 14.
4 is pushed downward by the positioning lever 27 via the compression spring 30. However, the escape block 14 does not rotate beyond the angle determined by the stopper screw 31.

Conveyor 9 on both sides of recess 28 of escape block 14
A support portion 32 for the component 2 is provided on the inside, and a positioning protrusion 33 for the component 2 is provided on the outside.

Holding protrusions 34 concentric with the shaft 20 are provided on both sides of the recess 28 of the escape block 14 in portions close to the shaft 20.

Next, the operation of this embodiment will be explained with reference to FIGS. 4 to 6. The part 2 conveyed by the conveyor 9 is attached to the support part 3 inside the positioning protrusion 33 of the escape block 14.
Proceed with both ends supported by 2. Then, the component 2 hits the holding protrusion 34 of the escape block 14 and stops. A detection groove 35 is provided between the holding protrusion 34 and the positioning protrusion 33, and when the component 2 hits the holding protrusion 34 and stops, the component 2 closes the detection groove 35. An infrared detector (not shown) detects that the component 2 closes the detection groove 35, and the motor 13 is started.

The rotation of the motor 13 is transmitted to the positioning lever 27 via the gears 22, 24 and the shaft 20.

When the positioning lever 27 is rotated, the magnets 25,26 come into contact with the frame 2 of the part 2. At the same time or a little later, the tip of the adjustment screw 36 attached to one end of the positioning lever 27 comes into contact with the escape block 14, and the escape block 14 also rotates together with the positioning lever 27. Part 2 is the magnets 25 and 26 of the positioning lever 27.
In addition, since the part 2 is positioned by the positioning protrusion 33 and the holding protrusion 34 of the escape block 14, the part 2 does not shift from the escape block 14 even if it becomes vertical, as shown in FIG.

When the product 2 is in the position shown in FIG.
grab.

When the chuck 16 grips the part 2, the motor 13 rotates in the opposite direction, and the positioning lever 27 rotates in the opposite direction until it returns to its original position as shown in FIG. Further, the chuck 16 that has gripped the component 2 advances to the front end of the next step 4 due to the rotation of the rotating portion 18. Retaining protrusion 34 of escape block 14
Since is concentric with axis 20, chuck 16 can rotate until escape block 14 returns to its original position as shown in FIG.

By using the magnets 25 and 26 to change the direction of the component 2, the component 2 can be reliably transferred with a simple structure.

Effects of the Invention As described above, the present invention has a converting section that holds a component using a magnet and changes the direction of the component, and a transfer section that transfers the component whose direction has been changed. It is not necessary, the configuration of the drive device is simple, and the direction change and transfer of parts can be performed reliably.
