Abstract

PURPOSE:To promote the safety of an operator by having an operating part enabled only at a time when respective operating parts, being selected by plural selecting means, are accorded with each other, in an operation unit where each operating part of a work unit is installed in plural spots. CONSTITUTION:A main side operating part selector switch 31 is selected to the sub side at a main operating part 24, and after a sub side operating part selector switch 32 is selected to the sub side at a sub operating part 25, and then a manual key 50 is pressed, whereby a part setting device is changed over to a manual mode, for example, a suction nozzle is interchanged. At this juncture, when another operator is to perform other regulating operations, etc., at the side of the main operating part 24, if operation is performed after selecting the main side operating part selector switch 31 to the main side at the main operating part 24, since each output of an AND circuit 33 and an AND circuit 34 comes to '0', even if a rotary panel operating key 48 is pushed, output of an OR circuit 55 remains '0' unchanged and the rotary panel will not operate any more, thus safety of an operator at the side of the main operating part 24 is well promoted.

) has been switched to the sub side that functions.

The two input terminals of the AND circuit (33) are connected to the changeover switch (31) and changeover switch (32), respectively, and the AND circuit is connected only when both the changeover switches (31) and (32) are switched to the main side. (33) is a high potential (hereinafter referred to as “1”)

The output of the AND circuit (37) and the AND circuit (40) is O.
The input to the R circuit (43) is complete, and the output of the OR circuit (43) is connected to the interface (2B).

The start keys (39) and (42) are used to start the automatic operation of the component mounting device (1), and any of the start keys (
39) When the output of the OR circuit (43) becomes ``14'' by pressing (42), the CPU (27) starts automatic operation. It is a switch, and it is closed while it is pressed, but when the pressure is released, it returns to its original state and becomes open.Once the start key is closed, it returns to its original state and becomes open, and the operation is automatic. Driving continues.

That is, when the changeover switches (31) and (32) are both on the main side, when the main side start key (39) is closed, the output of the AND circuit (37) becomes "1", and the interface (28) 11'' is input from the OR circuit (43) to start automatic operation. In this case, even if the sub-side start key (42) is closed, the output of the AND circuit (34> is "0", so the output of the OR circuit (43) remains "0."

If the changeover switches (31>(32) are both set to the sub side, the output of the AND circuit (33) will be 10.
Since the output of the AND circuit (34) is "1", the component mounting device (1) does not start even if the start key (39) is pressed, but starts when the start key (42) is pressed.

In addition, if one of the changeover switches (31) and (32) is switched to the main side and the other to the sub side, an AND circuit 33)
Since the outputs of (34> are both 10), no matter which start key (39) or (42) is pressed, the OR circuit (4

The sub-operation section (25) is also provided with a turntable operation key (48), an automatic key (49), a manual key (50), etc., each having the same function as each of the above keys.

The turntable operation keys (45) (48) and the start key (
39) Similar to the case of (42>), AND circuit (51)
(53), inverters (52) (54) and OR circuit (
55) to the interface (28). Furthermore, automatic keys (46) (49) and manual keys (47) (50) are also used as start keys (39) (49), respectively.
The connection configuration is similar to 2).

These turntable operation keys (45) (4g), automatic keys (4
6) (49), manual keys (47), (50), etc. are also automatic reset type switches like the start keys (39) and (42), and when pressed once, the CPU (27) is activated by the OR circuit. If the ``1'' output is latched and taken in from the interface (28), even if the switch returns to the open state, the operation to be performed will continue until it is completed, or the mode will remain the same.

The operation of the above configuration will be explained below.

When the main side operation section changeover switch (31) and the sub side operation section changeover switch (32) are both switched to the main side, the operator can use the main operation section (24) to press the automatic key (
46) and then presses the start key (39), the component mounting device (1) starts automatic operation.

First, when the printed circuit board (7) is conveyed to the supply conveyor (13), the reloading device (12) transfers the printed circuit board (7) onto the XY table (3).

Then, the component supply section servo motor (10) rotates, and the tape feeding device (9) that stores the desired component (6) moves the component supply table (8) to the suction station (18) of the rotary disk (15). Stop at. Then, one suction nozzle (16) is moved to the suction station (18) by the intermittent rotation of the rotary disk (15) caused by the rotation of the rotary disk servo motor (17).
It stops and picks up the parts 6).

Next, when the rotary disk (15) rotates and the nozzle (16) stops at the recognition station, the recognition device (19) recognizes the part (6) attracted to the nozzle (16). . The next rotation of the rotary disk (15) causes the nozzle (
16) stops at the angle correction station, the angle correction device (20) based on the recognition result by the recognition device (19)
corrects the angle of component (6).

Then, when the rotating disk (15) continues to rotate intermittently and the suction nozzle (16) stops at the mounting station (22), the X-axis servo motor (4) and the Y-axis servo motor (5)
), the XY table (3>) moves and the component (6) is mounted at the position where the printed circuit board (7) is to be mounted.

Next, in the suction station (18), after the first suction nozzle (16) suctions the component (6), the rotary disk (15) rotates and the next nozzle (16) moves the component supply table (8). The component (6) is taken out from the desired tape feeding device (9>), and after the above-mentioned operations, the printed circuit board (7) is removed.
) is mounted with the component (6). In this way, the parts (6) are mounted on the printed circuit board (7) one after another. When all the parts (6) have been attached to the board (7), the board (7) is transferred to the ejection conveyor (14) by the reloading device (12), and the ejection conveyor (14) removes the board (
7) Discharge. Then, the next printed circuit board (7) is placed on the XY table (3), and the parts (6) are mounted in the same manner as described above.

As described above, the parts (6) are mounted on the printed circuit board (7) one after another, and the planned number of printed circuit boards (
7> is discharged, the component mounting device 1) stops automatic operation.

Next, the operator performs various setup changes in order to automatically install the component (6) onto a different type of printed circuit board (7). It must be replaced according to the part (6) to be installed.

For this reason, the operator must first switch the main side operation section changeover switch (31) to the sub side using the main operation section (24), go to the component supply table (8) side of the component mounting device (1), and switch to the sub operation section. At (25), switch the sub-side operation section changeover switch (32>) to the sub-side.

Then, by pressing the manual key (50), the component mounting device (1) is put into manual mode, and then the suction nozzle (16) is replaced. For example, the suction nozzle (16) of the station one station before the suction station (18)
) is replaced, when the turntable operation key (48) is pressed, the input of the inverter (52) is grounded and becomes "0", so the inverted "1." is input to the AND circuit (51), and the AND Since the output of the circuit (33) is "1", the AND circuit (51) outputs "1°" and the OR circuit (5
5), "1" is input to the interface (28).

Then, the CPU (27) activates the rotary disk servo motor (17).
), the rotary disk (IS) rotates and picks up the next suction nozzle (1
6) stops at a station before the suction station (18), so the operator replaces the nozzle (16). In this way, the operator continues the work of replacing the suction nozzle (16).

At this time, if another worker attempts to perform other adjustment operations on the main operation section (24) side, the sub operation section (24)
5) The main operation section (24
), if you try to start work after switching the main side operation section changeover switch (31) to the main side, the AND circuit (
33) and the AND circuit (34) are rO, so even if the operator on the sub-operation unit (25) presses the turntable operation key (48), the output of the OR circuit (55) is rO. 0
．． If this is done, the rotary disk will not operate and the safety of the workers on the main operation section (24) side will be ensured.

In this case, the worker on the main operation unit (24) side operates the main operation unit (24) for adjustment, or the operator does not realize that a setup change is in progress and tries to activate the automatic operation by pressing the automatic key (46). Even if the start key (39) is pressed, the component mounting device (1) does not operate, and the safety of the operator on the side of the sub-operation section (25) is also ensured.

When there are workers on both the main operation section (24) and the sub-operation section (25) due to setup change as mentioned above, both parties will communicate and the other person will do the work instead of doing the work themselves. Switch (31) (
32) can now be switched.

When the above-mentioned setup layering is completed, the operator presses the sub-operation section (
25) If there is only one person on the side, use the sub operation section (25)
The automatic key (49) and start key (42) are pressed to cause the component mounting device (1) to perform the same component mounting operation as described above. After this, if you switch the sub-side operation section changeover switch (32) to the main side and switch the main side operation section changeover switch (31) to the main side at the main operation section (24), the main operation section (24) operation is possible.

In this embodiment, the main operation section (24) and the sub operation section (25) are provided with a main side operation section changeover switch (31) and a sub side operation section changeover switch (32), respectively. Even if a switch is provided to switch between the main operation section and the sub-operation section, the safety of the worker can be improved if it is difficult to see that the operator is working on the sub-operation section.

In addition, in the unimplemented example, due to the circuit configuration of an AND circuit, an inverter, and an OR circuit between each switch of the operation section and the interface (28), the main side operation section changeover switch (31) and the sub side operation section changeover switch (32) are connected. However, it is also possible to connect each switch directly to the interface and achieve the same functionality using software.

Furthermore, although this embodiment has been described with reference to the case where there are three operating units having the same function in a device for mounting chip-shaped electronic components on a printed circuit board, it is also possible to If a switch with the same function is provided on each of two or more operating sections due to the large size of the Alternatively, the switch may be provided in some of the operating sections so that the switch functions only when all the changeover switches are set to the same operating section position. Furthermore, it is also conceivable to provide the changeover switch at a position remote from the operating section where the switch group is arranged together.

In addition, there may be cases where only some operation sections have operation switches with specific functions, but in this case as well, if the operation switch is activated, it will affect the worker who is working on the value operation section. Therefore, if all the changeover switches are not switched to the position of the corresponding operation part, the operation switch should not function. The output of the AND circuit (33) or (34) is connected to the other input terminal of the AND circuit connected to one input terminal via an inverter, and the output of the AND circuit is connected directly to the interface (28) without passing through the OR circuit. ).

However, a switch or the like for stopping the working device in an emergency should be provided in each operating section so that it will function when pressed even if the changeover switch is not switched to the operating section.

(g) Effects of the Invention As described above, the present invention ensures the safety of the workers because the switching means switches and selects the same operation section only when all the operators of the respective operation sections agree. can be achieved.
