Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention is applicable to the assembly of electronic parts such as switches and volumes.
The present invention relates to a component supply device that assembles a component supplied in a hoop state as a single product.

Conventional technology Generally, when the parts that are supplied in the hoop state are changed from the hoop state to a single item, the peripheral edge of the part is cut with a mold, dropped and collected in a box, etc., and this single item is supplied for assembly. There is a method of aligning them with a parts feeder and supplying them. Hereinafter, a conventional component supply method will be described with reference to the drawings.

FIGS. 6 to 8 show a conventional component supply method,
Is a cutting punch, 2 is a part, 3 is a hoop material, 4 is a hoop guide, 5 is a cutting die, 6 is a parts box, and 7 is a parts feeder.

In the above configuration, the component 2 is fed horizontally along the guide 4 to the bottom face in the hoop state. When the part 2 is separated from the hoop material 3, the cutting punch 1 descends from the upper surface of the part 2 and pushes the part 2 downward, the cutting punch 1 and the cutting die 5 cut the part 2, and the separated part 2 is It falls naturally and is stored in the parts box 6. After that, a plurality of individual components 2 were put in the parts feeder 7, aligned and supplied.

However, according to such a conventional component supply method,
When the component 2 is dropped, the component 2 is damaged or bent, and at the same time, it is necessary to put the component feeder 7 into a certain posture again after it has been made into a single item, which is insufficient in terms of quality, productivity and facility cost. There was a point. In view of the above problems, the present invention provides at low cost a parts supply device capable of greatly improving quality and productivity by directly supplying parts separated and made into individual products to the next step.

Means for Solving the Problem In order to achieve this object, the present invention provides a hoop material on the upper surface of which a plurality of parts are continuously assembled at regular intervals and provides holes for individually cutting the parts. The cutting die connected to the upper surface of the hollow slide guide block, the hoop guide connected to the upper surface of the cutting die to guide the hoop material supplied from the outside, and the hole provided in the cutting die. A cutting punch that is attached so as to be able to move up and down and that individually cuts and separates the parts by inserting it into the hole, and a slider that is slidably mounted by horizontally inserting the outer wall of the slide guide block. The parts that are individually cut and separated by lowering the cutting punch connected to this slider are held in a fixed position, and while the parts are held, A pallet that carries the parts out of the slide guide block by sliding the slider, and a pallet that is inserted through the pallet when the parts are individually cut and separated so as to ascend and guide the bottom of the parts. The guide pin is mounted so that it can move up and down.

Operation With this configuration, when separating a part from the hoop material, the cutting punch and guide pins sandwich the upper and lower surfaces of the part and descend to mount the part on the pallet. By carrying out the parts, the parts can be supplied without breaking the posture of the parts in the hoop state, and moreover, the parts can be inexpensively configured with a simple mechanism.

Embodiment One embodiment of the present invention will be described below with reference to the drawings. 1 to 5 show a component supply device according to an embodiment of the present invention. 1 to 5,
11 is a cutting punch which has a cutting blade on the lower surface and is attached so as to be able to move up and down, 12 is a part consisting of a combined body of an operating body and a middle terminal, for example in the case of a volume, 13 is a state of this part 12 in a hoop state , 14 is a hoop guide that guides the hoop material 13, 15 is a cutting die having a hole into which the cutting punch 11 fits, 16 is a hollow shape in which a through hole for holding a slider is horizontally provided in the outer wall. Slide guide block, 17 is a slider slidably mounted in a hole formed through the outer wall of the slide guide block 16, and 18 is a recess for receiving the component 12 and a guide pin. A pallet attached to the slider 17 and a guide pin 19 which is attached to the lower surface of the component 12 through the pallet 18 so as to come up and down. A compression spring for biasing,
Reference numeral 21 is a guide pin holder for holding the guide pin 19, and 22 is a vacuum hole.

The operation of the component supply device configured as described above will be described below. First, the part 12 is a hoop material in the hoop state.
The upper surface of the cutting die 15 is fed horizontally along the hoop guide 14 along with the hoop guide 14. When separating the component 12 from the hoop material 13, first, as shown in FIGS.
19 passes through the pallet 18 and rises to receive the lower surface of the component 12.

Next, as shown in FIG. 3, the cutting punch 11 descends from the upper surface of the component 12, and the component 12 is cut by the cutting die 15 while the upper and lower surfaces of the component 12 are sandwiched together with the guide pins 19. The cutting punch 11 and the guide pin 19 continue descending while sandwiching the upper and lower surfaces of the component 12 that has been cut and separated, and the component 12 is inserted into the pallet 18, and the guide pin 19 further descends to a position where it is removed from the pallet 8. In this way, the pallet 18 having the parts 12 mounted thereon is moved by the slider 17 sliding in the direction of arrow A as shown in FIG.
It is possible to move to the outside of the cutting mechanism unit while maintaining the positional accuracy without breaking the posture of. Further, the guide pin 19 is floated by the compression spring 20, and the part 12 is attached to the lower surface of the cutting punch 11.
Is pressed so that the posture of the component 12 does not collapse.

Although the guide pin 19 is used in this embodiment,
As shown in FIG. 5, a vacuum hole 22 is provided in the cutting punch 11,
Depending on the shape of the component 12, it is possible to bring the component 12 up to the pallet 18 only by vacuum suction.

EFFECTS OF THE INVENTION As described above, according to the present invention, it is possible to supply a single component from the hoop material while maintaining the posture of the component with a simple structure, and the practical effect is great.
