Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a hopper-type magazine configured to store chip components and supply the stored chip components one by one in a predetermined direction, and in particular to This invention relates to a hopper type magazine that is optimal for use in a component feeder of a chip component mounting device that automatically mounts chip components onto electronic circuit boards.

Background technology and its problems As the demand for smaller and thinner electronic devices increases, the configuration of electronic circuits changes from the conventional configuration of electronic components with lead wires to high-density packaging circuits using chip components. Chip component mounting devices are now being used as devices that automatically mount chip components on electronic circuit boards. In such an apparatus, chip components are supplied one by one from a magazine of a component supply machine to a chucking head, and the chucking head grips and mounts the supplied components one by one.

However, due to a change in the board mounted on the chip component mounting device, (a) there is a change in the sorting sequence by type of chip components to be supplied, (b) it is necessary to supply a new type of chip component. When this occurs, a so-called setup change occurs in which the magazines are rearranged. This setup change work is essential for efficiently operating the chip component mounting apparatus.

However, conventional magazines are composed of a component supply pipe and a magazine case, and when changing the setup, it is necessary to remove the magazine case from the component supply pipe and discharge the components remaining in the pipe. However, discharging chip parts from inside this pipe takes a lot of time and is not easy to work with, and it is difficult to confirm whether the chip parts have been completely discharged, and the discharged parts are not completely recovered. It had the disadvantage that it could scatter inside the container and cause trouble.

Purpose of the Invention The present invention was made in order to eliminate the above-mentioned drawbacks.The purpose of the present invention is to enable attaching and detaching the magazine together with the parts supply pipe, thereby significantly reducing the time required to rearrange the magazines for changing types. It is an object of the present invention to provide a hopper-type magazine that can be shortened in size and prevent troubles caused by scattering of chip parts.

SUMMARY OF THE INVENTION In order to achieve the above objects, the present invention includes a hopper case portion having a hopper for storing chip components, a guide member with a pull-out stopper that guides the hopper case portion so as to be slidable up and down, and A magazine lower member is fixed to the lower part of the guide member, and one end is fixed to the magazine lower member and the other end is guided to be slidable up and down in a through hole in the bottom of the hopper and communicates with the inside of the hopper. The magazine includes a component supply pipe, a shutter provided at a component outlet of the magazine lower member communicating with the component supply pipe, and biasing means for biasing the shutter in a direction to close the component outlet. When the lower part is placed in a predetermined mounting position, the shutter opens the component outlet against the biasing means.

With the above configuration, the magazine can be attached and removed together with the parts supply pipe, so there is no need to eject parts from the parts supply pipe when rearranging the magazines, and the time required to rearrange the magazines is therefore greatly reduced. At the same time, troubles associated with flying parts and the like are also prevented.

24b) is connected to the bolt (22) via the compression spring (225).
6). In addition, a rod-type stopper (227) is installed downward in the center of the guide groove (223).
) is provided, and this stopper (227) is biased by a compression spring (228) to push the guide groove (223) from below.
Its head is protruding inside. The head of this stopper (227) is formed with an inclined surface (229) that is slanted in the direction in which the magazine is inserted, and this stopper (227) K has a rotation stopper (not shown). It has been subjected.

Next, insert the lower end of the magazine into the guide groove (223),
Since a taper (221) is formed at the entrance of the guide groove (223), the guide legs (211a) (211b) resist the compression spring (225) and press down on the presser plate (224a) (22
4b) while lifting the presser plate (224a) (224
b) and the guide groove (223). Therefore, if the magazine is pushed in as it is, the magazine will move forward, and when its bottom surface comes into contact with the inclined surface (229) of the stopper (227), the magazine will push down the stopper (227) and move forward. And a recess (23) formed in the bottom of the lower member (203) of the magazine.
0) and the stopper (227) match, the stopper (227) protrudes by the compression spring (225) and engages the recess (230), so the magazine stops, and in this state the magazine moves vertically and upwardly. It is fixed so that it does not move forward, backward, left and right, and is accurately positioned.

Therefore, when the hopper case (201) is pressed against the compression spring (215) in this state, the hopper case (201)
01) is guided by the guide shaft (202) and moves up and down, and when the suppression is released, it moves back by the spring force (215). Therefore, by continuing this operation, the parts supply nozzle (204) moves up and down within the hopper (205), promoting entry of the parts into the pipe (204).

On the other hand, when removing the magazine from the parts feeder, the mounting plate (
When the knob (231) of the stopper (227) protruding downward is pulled downward, the stopper (227)
Since the engagement between the and the recess (230) is released, if you slide the magazine to the removal side, the magazine will be attached to the guide shaft (
202), parts supply pipe (204), escape man) (21B), etc., and can be easily removed.

As mentioned above, since the guide shaft (202) is provided with a stopper, the hopper case (201) and the lower member (20) will not be accidentally separated.

In the magazine of the type in this second embodiment, the escapement (218) is integrated with the magazine, so no matter how the arrangement of the magazine in the parts feeder is changed, the parts fed into the hopper (205) As long as they are the same, the relationship between the parts and the escapement will always remain the same.

(Description of Component Delivery Device) Next, the chip component delivery device will be described (see FIG. 9 and FIGS. 13A to 14B).

The chip components supplied from the component supply pipe (167) of the magazine 00) are received one by one, and the received components are transferred to the chucking head (2) (same for (3)).
In order to feed between the chuck jaws, the escapement (feeding member) (152) and the rotating lever (154)
) are used. The escapement (132) is provided for each position where the component feeder (magazine GO on the rotation side of force) is attached, and the rotating lever (134) is provided only at the component feed position on the fixed side.

Escape Men) (132) is formed into a long rectangular parallelepiped, and the component receiving section (233) at its tip is approximately at the height of the chip components (the height of the components coming down from the component supply pipe (167) of the magazine). It is formed into a flat plate of equal thickness. and a guide groove (25) in the stepped outer edge (151) of the lower circular member (127) of the parts feeder (7).
5), this guide groove (255) and the lower annular member (
155) so as to be slidable while being guided by the upper surface (254). A return compression spring (258) is inserted between the inner four parts (256) and a stopper (237) fixed to the outer edge part (131), and the spring force biases the stopper. It is regulated by (2!17),
Escape Men) (132) is the parts receiving part (2
33) is configured to accurately return to a predetermined relative position and stop with respect to the component outlet (175) of the magazine 00).

Escape Men) (132) parts receipt 9 copies (253
), for example, a square tip (rectangular tip) (23
In the case of 9), as shown in Fig. 13B, the chip has the same rectangular shape as the chip to be supplied, but is slightly thicker, i.e., has a shape and size suitable for inserting the descending component as it is. A rectangular through hole (240) is formed. The opening (240) passes through the center of the through hole (240) at the end.
A rectangular cutout hole (242) having a diameter of 1) is connected to a through hole (
240) and is formed in the sliding direction of escape men) (132).

On the other hand, the tip of the chuck part of the chucking head (2)
The chuck jaw (!i31 is the escapement (1
The chuck claw 64) is formed wide enough to accommodate the component receiving part (233) at the tip of the chuck 9), and the chuck claw 64) is formed narrow enough to pass through the notch hole (242). ing.

With the above configuration, the parts (239) supplied from the magazine 00) are delivered to the escapement member (132) that is stopped at a predetermined receiving position through the through hole (24) at the tip.
0) and placed on the upper surface (234) of the lower annular member (135) while being held within the through hole (240). However, since this through-hole (240) is formed to have almost the same shape and dimensions as the chip component (239) to be inserted, the inserted chip component will not be misaligned (falling down within this through-hole (240)). I never wake up. Therefore, from this state, the escape man (1!12) is pushed by the rotating lever (154) and the chuck jaw 1!
Also when moving up to 1131, chip parts (2'59)
is held in a stable state within the through hole (240), and is moved as it is onto the wide chuck jaw G3).

In this state, that is, with the component (239) being held in the through hole (240) of the escapement (132) on the wide chuck claw (531), the chucking head (2) is rotated in the direction of arrow a. When the chuck jaws 5 on the rotating side are moved, the chuck jaws 5 on the rotating side are closed by the biasing force of the tension spring as described above, and the part (239) is chucked between both chuck jaws (531e'i4).At the same time, the chuck jaws 5 on the rotating side close ( 54)
The part (259) passes through the notch hole (240) and moves in the direction of the arrow a while holding and chucking the neck of the part (259). Therefore, the part (239) is held in the through hole (240) of the escape member (132) and is twisted and chucked, and then passed through the through hole (240) and moved to the mounting position. There is no possibility of chucking failure due to multi-positional misalignment of parts.

Note that when the chuck claw l53) passes through the notch hole (242), the rotary lever (134) moves back, so that the escape man (132) returns to the predetermined component receiving position by the spring force (238). When it returns, the chip component (239) comes down from the magazine again and enters the through hole (24).
0), so the escapement (132)
is pushed by the rotating lever (134) and moves forward again, and the chuck claw l53)6 of the chucking head 2) returns.
4) Repeat the operation of feeding and discharging the parts in between.

What is shown in FIGS. 14A and 14B is a case where the component is a cylindrical chip (245), and in this case, a circular through hole (244) that fits this cylindrical chip (243) is formed. . The notch hole (242) through which the chuck claw 64) passes has an opening (241) at the p end whose center passes approximately through the center of the through hole (244), as in the case of the square chip. , and is formed in a rectangular shape that intersects the through hole (244), and the width of this rectangle is slightly smaller than the diameter of the through hole (244).

In the magazine (second embodiment) described in FIGS. 11 and 12, the shape of the component receiving portion 9 at the tip of the escapement (21B) is exactly the same as that described above. The only difference is that the surface corresponding to the guide surface (234) in FIGS. 14A and 15A on which parts are placed is the guide groove (21(S)) of the lower member (203) of the magazine itself.
(217).

Therefore, the magazine of this second embodiment can also achieve the same effects as the magazine of the first embodiment.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, the hopper case portion is connected to the magazine lower member via the guide member,
On the other hand, a component supply pipe fixed to the magazine lower member communicates with a hopper in the hopper case section. At the parts outlet of the lower part of the magazine that communicates with this parts supply pipe, when this lower member is removed from the specified position, the part outlet is always closed, and when the lower part is removed from the specified position, the lower part is placed in the specified position. A shutter is provided to open the parts exit. Therefore, the magazine can be attached to and removed from a predetermined position without spilling the parts along with the parts supply pipe. And since the guide member is equipped with a stopper,
There is no chance of the hopper case part coming out and spilling parts during attachment/detachment.

Therefore, according to the present invention, when rearranging the magazines, there is no need for the work of discharging the parts from the parts supply pipe as in the past, so the time involved is significantly shortened, and
Trouble associated with parts scattering is also prevented, and productivity is significantly improved.
