Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a parts supply device that supplies parts intermittently.

A hybrid integrated circuit is one in which various circuit parts are configured in the form of chips, and these chip-like parts are mounted on a circuit board. The applicant of the present application has proposed a component supply device used for manufacturing such hybrid integrated circuits in Japanese Patent Application No. 58199/1983.
In this device, a means for holding a component is provided in the component supply passage, and when the shutter is opened, the second component counted from the shutter is crimped and held against the wall of the passage. . Therefore, only one component is supplied by opening the shutter, making it possible to supply components intermittently.

However, since the outer surface of the chip-shaped circuit component is coated with resin, it is somewhat sticky, and when the component is pressed against the wall of the passageway by the holding means, it tends to stick to the wall. become. Furthermore, in the passage, the end surfaces of adjacent components tend to adhere to each other. In this case, there is a problem in that even if the shutter is opened, components are not supplied, and therefore a predetermined circuit cannot be obtained.

The present invention has been developed in view of these problems.A shutter is provided near the lower end of the parts supply passage and across the flow of parts falling from the lower end, and parts are supplied to this shutter. A component holding means is disposed in the component supply passage on the upper side in the direction and holds the component by pressing it against the wall surface of the component supply passage, and when the shutter is opened, the component holding means is disposed in the upper part supply passage. Make sure to hold the second part counting from the bottom side,
In this apparatus, in which only one component is supplied from the component supply passage by opening the shutter once, in order to separate the component from adhesion to the wall surface or adjacent components, A rotary plate having an oval shape is configured to be freely retractable through a slit in the supply passage, and a component is dropped from the lower end of the component supply passage when the shutter is opened, and released from the pressing of the component holding means when the shutter is closed. The present invention relates to a component supply device in which each component is pressed by the rotary plate to ensure that the component falls down. Therefore, even if parts adhere to the wall surface of the supply passage, or even if the end surfaces of adjacent parts in this supply passage adhere to each other, they will always be separated by the rotating member, and the parts will be reliably separated into one piece. will be supplied separately.

An embodiment of the present invention will be described below with reference to the drawings.
As shown in FIGS. 1 to 3, a chip-shaped circuit component 1 is housed in a cylindrical hopper 2. As shown in FIGS. This hopper 2 is made of transparent synthetic resin, and the chip-shaped parts 1 inside are visible. A dish-shaped bottom plate 3 is fixed to the bottom of the hopper 2, thereby closing the bottom of the hopper 2. The inside of the bottom plate 3 has a conical shape, and a through hole 4 is formed in the center thereof to pass through in the axial direction. A capture pipe 5 is inserted through the through hole 4. The upper end of the capture pipe 5 has an inclined cut part, and is opened at this cut part and faces into the hopper 2. Therefore, hoppa 2
When a relative axial movement takes place between the cap and the pipe 5, the chip 1 in the hopper 2 is captured by the cap pipe 5. Moreover, the inner diameter of the cap pipe 5 is set to a value smaller than the length of the cylindrical chip-like part 1 and a value slightly larger than the outer diameter of the part 1, so that the chip-like part 1 They are aligned vertically within the interior.

The capture pipe 5 is fitted into and supported by the upper end of a component supply passage 7 formed vertically through the support block 6. Note that this passage 7 is composed of a circular through hole, and the part where the pipe 5 is fitted has a large diameter, and the other parts have the same diameter as the inner diameter of the pipe 5. There is. Further, a guide block 8 is fixed to the lower side of the support block 6. This block 8 also has a discharge hole 9 formed of a circular through hole. The axis of this hole 9 and the axis of the passage 7 coincide with each other, so that the passage 7
Parts are supplied to the hole 9 from the hole 9.
A step 10 is formed at the upper end of the guide block 8, and this step 10 forms a slit between the pair of blocks 6 and 8. A shutter 11 is disposed within this slit, in other words near the lower end of the component supply passage 7. This shutter 11 therefore controls the movement of parts from the passage 7 to the hole 9.

Two rollers 12 are rotatably supported on the front surfaces of the support block 6 and the guide block 8, respectively. Concave grooves 13 are formed in the outer circumferential surface of each of these rollers 12 along the circumferential direction. A shutter support frame 14 is movably supported by these rollers 12. That is, the frame 14 has protrusions 15 formed on its upper and lower surfaces, respectively, and these protrusions 15 engage with the grooves 13 of the rollers 12, so that the frame 14 can be moved left and right in FIG. Supported. This frame 14 has the shutter 1
1 is fixed. Therefore, the shutter 11 is adapted to move together with this frame 14.

A rack 16 is also secured to the frame 14. Rack 16 meshes with pinion 17. The pinion 17 is rotatably supported on the front surface of the support block 6, and this pinion 17
A gear 18 is coaxially fixed to the. The gear 18 is meshed with the gear 19. This gear 1
9 is a bracket 2 attached to the support block 6
It is rotatably supported by a bearing 21 provided at 0. A substantially oval rotating plate 22 is fixed to the other end of the rotating shaft to which the gear 19 is fixed. The rotary plate 22 is inserted into a slit 23 formed in the support block 6 and continuous with the component supply passage 7. Further, the bearing 21 is held down by a holding plate 24 fixed to one side of the frame 14.

A bracket 25 is fixed to the other side of the frame 14, and a holding pin 26 serving as a component holding means is slidably supported by this bracket 25. This pin 26 is attached to the support block 6.
It passes through a through hole 30 formed in the hole 30, and its tip crosses the component supply passage 7. A flange 27 is connected to the pin 26, and a compression coil spring 28 is interposed between the bracket 25 and the flange 27. Therefore, the pin 26 is urged to slide to the left in FIG. 2 by the spring 28. This pin 26 presses and holds the chip-shaped component 1 against the wall surface of the component supply passage 7. Further, a retaining ring 29 is attached to the pin 26.

Next, the operation of the component supplying apparatus having the above structure will be described. As shown in FIG. 2, a predetermined amount of chip-shaped components 1 are stored in the hopper 2. Then, relative movement in the vertical direction is made between the hopper 2 and the capture pipe 5. In the apparatus of this embodiment, the capture pipe 5 is fixed, and the hopper 2 is arranged to move up and down in the axial direction of the capture pipe 5. Due to this movement, the chip-shaped part 1 is captured by the capture pipe 5 in a vertically aligned position. Since the cap pipe 5 communicates with a component supply passage 7 formed in the support block 6, the chip-shaped component 1 is guided into this passage 7. However, at this time, since the shutter 11 blocks the passage 7 and the hole 9 of the guide block 8, the chip-shaped part 1 is prevented from falling downward.

When a drive mechanism (not shown) presses the frame 14 to the left in FIG. 1 via a pressing pin 31 provided on the frame 14, the frame 14 is guided by the four rollers 12 and moves to the left. Then, the shutter 11 fixed to the frame 14 also moves and opens as shown in FIG. The first chip-shaped part 1 immediately above this shutter 11 therefore falls and is guided into a predetermined position through the discharge hole 9. Moreover, at this time, the second component 1 on the upstream side counting from the shutter 11 is held by the holding pin 26 and does not fall. That is, as the frame 14 moves to the left, the bracket 25
2, the compression coil spring 28 is compressed, and the elastic restoring force of the spring 28 pushes the flange 27 and pushes the pin 26 to the left. For this reason, the second chip-shaped component 1 is pressed against the inner wall surface of the component supply passage 7 and will not fall.

Even if the shutter 11 is opened, if the component 1 directly above the shutter 11 is stuck to the wall surface of the passageway 7 or the component 1 above it, there is a possibility that the component 1 will not fall. Therefore, the adhered component 1 is forcibly dropped by the rotary plate 22. That is, when the frame 14 moves to the left, the rack 16 attached to the frame 14 also moves in the same direction, thereby causing the pinion 17 to rotate. This rotation is carried out by the rotating plate 2 through gears 18 and 19.
2, and this rotating plate 22 rotates clockwise in FIG. The rotary plate 22 is formed into a substantially oval shape, and since its long diameter side hits the component 1, the component 1 is surely dropped.

When the shutter 11 is opened and the component 1 immediately above it is reliably sent downward, the frame 14 is moved to the right via the pin 31 by a drive mechanism (not shown). As a result, the shutter 11 is closed as shown in FIG. 5, and the passage 7 and the hole 9 are blocked. Further, as the frame 14 moves to the right, the bracket 25 also moves to the right, and this bracket 25 pushes the retaining ring 29 of the holding pin 26 to the right. As a result, the holding pin 26 moves back and releases the holding of the second component 1 counted from the shutter 11. This part 1 thus falls and rests on the closed shutter 11. If the component 1 remains stuck to the wall surface of the passage 7 even after being released from holding, it is forcibly dropped by the rotary plate 22. That is, by moving the frame 14, the rack 16,
Rotating plate 2 via pinion 17 and gears 18 and 19
2 rotates counterclockwise in FIG. In this way, one cycle of operation is completed. This operation is repeated to ensure that the parts 1 are intermittently supplied one by one.

As described above, the present invention is provided with a rotating member that separates the parts attached to the wall of the component supply passage from this wall, so that the parts are reliably supplied one by one intermittently and the equipment is Improved reliability.
