Description

[Detailed description of the invention] [Field of industrial application] This invention relates to the technical field of attaching electrical components to a circuit board such as a printed circuit board by soldering etc. The present invention relates to a device for supplying electrical components to be inserted to a worker when inserting electrical components into a circuit board.

[Conventional technology]

2. Description of the Related Art A component insertion instruction device is generally used as an auxiliary tool or jig for inserting electrical components into a printed circuit board. Conventionally, when performing insertion work using this component insertion instruction machine, in order to supply electrical components to a worker, electrical components must be stored in multiple component storage boxes arranged in a chain according to the insertion procedure. These parts storage boxes were transported sequentially so that they could be brought to the operator's side one by one.

However, when transferring component storage boxes in this sequential manner, the number of electrical components in the component storage box changes each time the electrical component insertion procedure changes due to transition from one particular insertion operation to another. There was a problem in that it was inconvenient and complicated to replace the parts. On the other hand, it is not impossible to eliminate the need to replace electrical components by transporting component storage boxes arranged in a chain in this way using a random access method, but if this is done, access There was a problem in that it took too long and work efficiency decreased significantly.

On the other hand, a component supply device that does not employ the sequential method is disclosed in Japanese Patent Publication No. 14038/1983. There, multiple drums with multiple parts boxes arranged in the circumferential direction are arranged in multiple layers.
A component feeding device is shown in which a drum can be selectively rotated to feed desired components. There, a plurality of drums are fixedly arranged along one main shaft having a predetermined length, and the drums selected by a solenoid are rotated in common according to the rotation of one main shaft motor. ing.

[The problem that the idea aims to solve]

In the conventional component feeding device using the above-mentioned multilayer drums, multiple drums are fixedly arranged along one main axis of a predetermined length, so the number of drums cannot be changed flexibly, making it highly versatile. was lacking. Furthermore, since each drum is commonly driven by the main shaft, it is not possible to efficiently move the drum returning to the origin and the drum moving to the desired position in different ways at the same time, and there is a limit to shortening the access time. Furthermore, if the main shaft malfunctions, all the drums become unrotatable, which is inconvenient in the event of a failure and requires troublesome maintenance. Furthermore, since the drum is fixedly arranged along the main shaft, it is troublesome to replace or change the drum, and it is therefore difficult to change specifications such as the size and depth of the parts box.

This idea was made in view of the above points,
The number of component storage trays can be changed flexibly, access time can be shortened, maintenance is easy, and
It is an object of the present invention to provide an electrical component supply device in which a component storage tray can be easily replaced and changed.

[Means to solve the problem]

In the electrical component storage device according to this invention, one unit includes a component storage tray provided with a plurality of component storage recesses provided along the rotation direction and at least one notch, and the tray. It is equipped with a support part that supports the tray rotatably, a drive device for rotating the tray, and an engagement part that enables vertical combination of other units, It has a structure in which units are stacked vertically in multiple layers via the engaging portions, and the trays of each unit can be rotated independently by each drive device, and the number of unit stages can be increased or decreased as desired. This is a characteristic feature.

[Effect]

By rotating each component storage tray by a predetermined angle using each drive device, the electrical components stored in any component storage recess of any component storage tray can be brought to the operator's side. That is, for electrical components in each component storage recess of a component storage tray other than the top layer component storage tray, all the notches of component storage trays located above the tray are positioned directly above the recess. By determining the rotation angle of the upper component storage tray, it can be made to face the operator. Moreover,
The access time required in this case is no more than the time required to rotate one component storage tray by half a rotation at most. Therefore, by randomly accessing these component storage recesses and placing desired electrical components facing the operator, electrical components can be supplied in a short time during each insertion operation without having to replace electrical components. You will be able to do this.

Furthermore, since an arbitrary number of trays can be increased or decreased in unit units, the number of trays can be changed flexibly and is highly versatile.

In addition, since the trays of each unit can be rotated independently by each drive device, each tray can be rotated simultaneously in different ways, and the desired part can be moved by moving the desired tray over the shortest distance independently of the others. access time can be shortened.

In addition, each unit is independent and can be easily replaced, so in the event of a malfunction such as malfunction of the tray, it can be easily removed and replaced immediately, making maintenance easy. It is.

In addition, since the tray can be easily replaced or changed with a tray having different specifications such as the size and depth of the component storage recess, flexibility according to the work content can be obtained.

〔Example〕

Hereinafter, one embodiment of this invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows an embodiment of an electrical component supply device according to this invention. This electrical component supply device 1 includes a case base 3 in which a disk-shaped component storage tray 2 is rotatably and detachably supported on a tray support 3a.
A plurality of units (five units in the figure) are provided in a multilayered manner supported by case base columns 11. As a result, each tray 2 also has a multilayered structure. A disk-shaped tray cover 4 is attached to the upper end of the support column 3a of the case base 3 in the uppermost layer so as to cover the tray 2 supported by the support column 3a.

FIG. 2 shows details of the structure of the case bases 3, the relationship between each case base 3 and the case base 3 located directly below it, and the manner in which the tray 2 is supported by each support column 3a. A ring portion 3b is provided on the lower surface of the case base 3, and the upper end of the support column 3a of the case base 3 located directly below is inserted into the center of the ring portion 3b of each case base 3. This prevents the case bases 3 from being displaced from each other in the horizontal direction. Further, a ring-shaped thrust bearing 5 is provided around the lower end of the support column 3a on the upper surface of the case base 3, and a tray mounting plate 6a for rotatably supported by the support support 3a and for mounting the tray 2 is provided. A rotating part 6 is supported on this bearing 5. The tray 2 is mounted on a mounting plate 6a of the rotating section 6 and supported by a support column 3a. Furthermore, the first
In the figure, illustration of the recess 3b, bearing 5, and rotating part 6 is omitted.

An example of the configuration of the tray 2 is shown in FIG. 3. The tray 2 is provided with a hole 2a in the center having an inner diameter corresponding to the diameter of the support column 3a.
A plurality of component storage recesses 2b (seven in the figure) for storing electrical components are provided along the circumferential direction on the upper surface. In addition, the tray 2 has one recess 2.
A notch 2c having an area approximately equal to b is provided at one location. Although not particularly shown, the tray mounting plate 6a of the rotating section 6 is also provided with a notch of approximately the same size as the notch 2c, and the tray 2 is arranged so that the notch 2c is located directly above this notch. It is mounted on the mounting plate 6a. Further, as shown in FIGS. 5 and 6, the tray cover 4 is also provided with a notch 4a of approximately the same size as the notch 2c.

As shown in FIG. 4, a motor 7 and a driven wheel 8 are mounted on each case base 3.
The rotating shaft of the motor 7 and the lower end portion of the rotating portion 6 supported by the thrust bearing 5 are connected by a belt 9 oriented by a foil 8 . As a result, the rotating section 6 and the tray 2 mounted thereon are rotated around the support column 3a by the drive of the motor 7. In addition, in FIG. 4, the rotating part 6 and the support column 3
The tray 2 and the portions other than the lower end of the case base 3 are removed, and a part of the side wall of the case base 3 is cut away. In addition, in Fig. 1, the motor 7, the wheel 8,
Illustration of the belt 9 is omitted.

Electrical component supply device 1 having such a configuration
In order to use the device 1 when inserting electrical components into a printed circuit board, the device 1 containing the electrical components in an appropriate arrangement in each recess 2b is placed near an insertion instruction device (not shown), and then the fifth As shown in the figure, for example, first cut out the notches 2c of all the trays 2,
Align it directly below the notch 4a of the cover 4 and face the operator. When the insertion work is started, the recess 2 containing the electrical component to be inserted first is inserted.
By rotating the tray 2 to which b belongs by a predetermined angle by the drive of the motor 7 on the case base 3 supporting the tray 2, this recess 2 is removed.
b is positioned directly below the notch 4b.
Then, as shown in FIG. 6, this recess 2b (in the figure, the recess 2b belonging to the third tray 2 from the top)
Since the electric component 10 inside faces the operator, the operator can take it out and insert it into the printed circuit board on the insertion instruction device. In addition, illustration of the motor 7, the wheel 8, and the belt 9 is omitted in FIGS. 5 and 6.

When this extraction is completed, the tray 2 to which the recess 2b containing the electrical component to be inserted second belongs is rotated by a predetermined angle by the motor 7 on the case base 3 supporting the tray 2. The recess 2b is located directly below the notch 4a. At the same time, at least when the tray 2 to which this recess 2b belongs is located lower than the tray 2 to which the first recess 2b belongs, the recess 2 described above
By rotating the tray 2 to which b belongs again by the motor 7 on the case base 3 that supported the tray 2, the notch 2c of the tray 2 is positioned directly below the notch 4a again. As a result, the electrical components in the recess 2b also face the operator in the same manner as in FIG. 6, so that the operator can take them out and insert them into the printed circuit board on the insertion instruction device.

Below, the recess 2b that accommodates the electrical components to be inserted
These electrical components can be sequentially supplied to the worker by sequentially and randomly accessing them by driving the motor 7 to face the worker. When all the electrical parts to be inserted have been supplied, each motor 7 is driven to make all the notches 2c face the operator again as shown in FIG. 5, for example.

Incidentally, such driving of each motor 7 is achieved by creating a computer program using a well-known method to control the drive of each motor 7 in accordance with the procedure for inserting electrical parts, and using a well-known computer (not shown) containing the program. This can be done by controlling each motor 7 with a control means. Therefore, the details will not be shown here.

In this way, this electrical component supply device 1 supplies electrical components by randomly accessing each recess 2b, but the access time required at this time is at most the time it takes to rotate a certain tray 2 half a turn. It's just the time it takes. Also, each tray 2
can be rotated at a relatively high speed by the motor 7. Therefore, according to this device 1, electrical components can be supplied in a short time in any insertion procedure without having to replace the electrical components.

Furthermore, according to this electrical component supply device 1, an appropriate number of independent case bases 3 can be provided in a multi-layered manner, so the number of case bases 3 can be adjusted according to the type and quantity of electrical components to be inserted. Adjustment allows efficient configuration of the device and provision of electrical components.

Further, according to this device 1, in a state where no other case base 3 or tray cover 4 is present on the upper layer of the case base 3, the tray 2 can be easily moved to the support column 11 of the case base 3 in a short time. It can be attached and detached. Therefore, even if it becomes necessary to replace the electrical component in each recess 2b with a completely different electrical component due to, for example, a difference in the circuit board into which the electrical component is inserted, the tray 2 itself can be removed from the support 11. Efficient replacement can be performed by removing the tray 2 and attaching another tray 2 containing another electrical component to the column 11.

Next, FIG. 7 shows another embodiment of the electrical component supply device according to this invention. This electrical component supply device 1
2, a plurality of case bases 3 supporting component storage trays 2 are provided in a multi-layered manner (four in the figure) in exactly the same way as the electrical component supply device 1 shown in FIG. A case base 3 that rotatably and detachably supports the unit 13 on a support 3a.
is located on the top layer.

An example of the configuration of the IC component storage unit 13 is shown in FIG. The unit 13 has holes 14a similar to the holes 2a and notches 2c of the tray 2,
It includes a disc-shaped plate 14 provided with a notch 14b, and this plate 14 is rotatably and detachably supported by the support column 3a. plate 14
A plurality of sets of holders 1 are arranged along the circumferential direction on the upper surface of the
5 is attached. Between each set of holders 15 is a dispenser 1 for storing and supplying IC elements.
6 are removably supported by screws or the like. (In FIG. 8, only two sets of holders 15 and a total of four dispensers 16 supported by these are shown, and illustrations of the other holders 15 and dispensers 16 are omitted.) The dispensers 16 are, as is well known, , multiple pieces stored in the stake 17
IC elements can be supplied one by one according to the operation of a predetermined operator.

The manner in which the unit 13 is supported on the support column 3a and the manner in which the unit 13 is rotated are shown in FIGS. 2 and 4.
It is exactly the same as shown for tray 2 in the figure.

Electrical component supply device 12 having such a configuration
By randomly accessing each recess 2b and each dispenser 16 in the same manner as already shown for the electrical component supply device 1, IC elements and other electrical components can be supplied in the same manner as the electrical component supply device 1. You will be able to do this.

[Effect of idea]

As described above, according to the electrical component supply device according to this invention, electrical components can be supplied without replacing electrical components when transitioning from one insertion operation to another, and moreover, each insertion operation can Electrical parts can be supplied in a short time during work. Therefore, the efficiency of the work of inserting electrical components into the circuit board can be improved as a whole.

In addition, according to this invention, the number of trays can be increased or decreased in unit units, so the number of trays can be changed flexibly depending on the purpose of use, and efficient parts supply work can be performed. It has the effect of being highly versatile and versatile. In addition, since the trays of each unit can be rotated independently by each drive device, each tray can be rotated in different ways at the same time. The effect is that the tray can be rotated to a desired position in the shortest distance, and the time required to access a desired component can be shortened. In addition, each unit is independent,
Since it is easily replaceable, in the event of a malfunction such as malfunction of the tray, it can be easily removed and replaced or other measures taken immediately, resulting in easy maintenance. In addition, since the tray can be easily replaced or changed with a tray having different specifications such as the size and depth of the component storage recess, flexibility can be achieved depending on the content of the work.
