A component supply table, a table guide device for movably guiding the component supply table in a direction parallel to the straight line, and component supply parts of a plurality of component supply units as supply positions for supplying components to the component mounting device. Some include a table moving device for moving the component supply table to perform unit selection for one-time positioning. The component supply units are mounted on the component supply table in the number corresponding to the types or the number of electronic components to be mounted on the printed circuit board. By moving the component supply table, the component supply unit of each unit mounts the electronic component on the printed circuit board. The electronic components are supplied to the component mounting device by being positioned at the supply position in order.

[0004]

Generally, the type or number of electronic components mounted on one printed circuit board is not so large, but in many cases, the component supply table is provided with the electronic components mounted. Since it is made assuming that the number of types or number is the largest, it will be large, and the table moving device will have to have a large driving force, and since the inertia is large, the responsiveness will be poor and high speed operation will be difficult. There was a problem of inefficiency. In addition, there is a problem in that a large amount of vibration is generated when the component supply table starts to move or stops, the direction of the electronic component may be changed or tilted, and an error in holding the electronic component by the component mounting device may easily occur. Further, when only one component supply table is provided in one mounting device, if there are no electronic components in the component supply unit on the component supply table, the mounting device is stopped and the component supply unit is replaced or There is also a problem that the operating rate of an expensive mounting device is lowered because electronic parts must be replenished. The present invention has been made with the object of obtaining an electronic component supply device capable of solving these problems.

[0005]

To this end, in the electronic component supply apparatus according to the present invention, (1) a component supply unit that holds a large number of electronic components of one type each has a linear component supply unit.

[0006]

With the size of the first component supply table and the second component supply table, the component supply units required when the types or the number of electronic components mounted on the printed circuit board are not so large are all included in one table. If the number or types of electronic components to be mounted on the printed circuit board is the largest, the size of the components supply unit should be large enough to use all the component supply tables. Thus, when one component supply table is sufficient for supplying electronic components to be mounted, only one component supply table is moved, and when there are many electronic components, both component supply tables are alternately or simultaneously used. Electronic components can be supplied by moving them. Then, if the supply of components by one component supply table is completed due to the completion of the supply of the planned amount of components, the supply end detection means detects it.
In response to this, the setup changer performs automatic setup change. This automatic setup change may include necessary changes in addition to program changes and table changes.

[0008]

In the component supply apparatus of the present invention, the first and second component supply tables are compared with the conventional ones which are made assuming that the type or number of electronic components to be mounted is the largest. Since it can be made small, the responsiveness is good, and it is possible to move at high speed to improve the work efficiency. Moreover, the vibration generated at the time of starting and stopping the movement is small, so that It is less likely that the direction will change or tilt, and the effect of reducing component supply errors can be obtained.

If the number or types of electronic components to be mounted on one printed circuit board is small and all the required electronic component supply units can be mounted on one component supply table, then both component supply tables can be mounted respectively. By mounting different combinations of electronic components, if component supply by the operating component supply table is completed,
Since the component supply table can be moved to the save area while the other component supply table is moved to the work area and the electronic component can be supplied by the component supply table, it is necessary to change the electronic component to be supplied. The setup change can be automatically completed in a very short time.

When it is necessary to replace the component supply unit on the component supply table that has been retreated to the retreat area or to replenish the electronic components, the necessary work is performed while the electronic component supply table is in the retreat area. Can be done. Since it is not necessary to stop the component supply device during these operations, the effect of improving the component supply efficiency can be obtained.

Moreover, since the above setup change is automatically performed, it is not necessary for an operator to be near the component supply device at the time of setup change, and while the next component supply table is performing component supply, After the component supply is completed, the component supply unit on the component supply table may be replaced or the electronic component may be replenished.

Further , the preparation completion detecting means and the table exchange

U170 also has a ROM (Read Only Memory) 17
4 and a RAM (random access memory) 176 are connected. In the ROM 174, a program of three component mounting modes that can be executed by the mounting apparatus is started, and components are mounted according to the types of electronic components to be mounted on the printed circuit board, the mounting position, the mounting order, the moving order of the printed circuit board, and the mounting order of the electronic components. A program and the like for moving the component supply tables 95 and 99 so as to supply electronic components to the mounting device 18 are stored.

The CPU 170 further includes a first component supply table moving motor drive circuit 178, a second component supply table moving motor drive circuit 180, a substrate loading device drive circuit 182, a substrate unloading device drive circuit 184, and a substrate support device drive. The circuit 186 and the component mounting device drive circuit 188 are connected to the motor 156 and the motor 15 respectively.
8, the board loading device 12, the board unloading device 14, the board supporting device 16, and the component mounting device 18 are connected, and the tape end detection is performed via the interface 190 to detect that the electronic components of the component supply unit 98 are gone. A sensor 192 and a display device 194 (see FIG. 2) for indicating to the operator that the size of the printed circuit board to be mounted changes are connected.

Programs for the three component mounting modes,
The drive motors 156, 158 and the feed screw 15 are the programs for moving the parts supply tables 95, 99 and the part of the control device for executing these programs.
2, 154 and the motor drive circuits 178 and 180 together form a table moving device.

3 which can be executed by this electronic component mounting apparatus
One of the component mounting modes can be selected by the operator by operating a mode selector switch (not shown). Normally, electronic components are mounted in the first mode shown in the flowchart of FIG. This mode
This is a case where the number or types of electronic components mounted on one printed circuit board is not so large, and all the required component supply units 98 can be mounted on either one of the tables 90 and 92. In addition, in FIG. 10, the operation described in the solid line frame is due to the mounting device,
What is described within the frame of the chain double-dashed line is due to the manual work of the operator, and this is the same for FIG. 11.

In this mode, prior to the start of operation, the type of printed circuit board on which electronic components are mounted is input, and the component supply unit 98 required for mounting the electronic components is input.
The tables 90 and 92 are mounted in a predetermined order. The mounting order may be the order of mounting the electronic components on the printed circuit board or may be different, but in any case, it is predetermined, and the tables 90 and 92 are determined according to the mounting order and the mounting order of the electronic components on the printed circuit board. The movement path within the work area of is set and stored in the ROM 174. Both the tables 90 and 92 have been evacuated to the evacuation area before the operation is started.
After mounting 8 to form the first component supply table 95 and the second component supply table 99, if the mounting apparatus is operated, the first component supply table 95 is moved to the work area, and the component supply unit 98 is sequentially operated. Positioned at the supply position 160, the electronic component is supplied to the component mounting device 18, and the component mounting device 18 receives the electronic component and mounts it at a predetermined position on the printed circuit board.

When any one of the plurality of component supply units 98 runs out of electronic components, the tape end detection sensor 192 detects it.
This detection can be performed, for example, by causing the sensor 192 to generate a signal when the suction pipe 86 has not sucked the electronic component twice in a row.
0 is the first component supply table 95 based on this detection signal.
The second component supply table 9 while moving the
9 is moved to the work area, and the second component supply table 99 is supplied with electronic components. The worker is informed that the electronic parts are exhausted by means of a parts end notification means such as lighting of an indicator lamp provided on the main body frame 10, and the worker replaces the parts supply unit 98, which has no electronic parts, with a new one. After that, the end of the exchange is input to the CPU 170. Then, when one of the electronic components of the component supply unit 98 mounted on the second component supply table 99 runs out, the CPU 170 moves the second component supply table 99 to the retreat area based on the signal of the sensor 192. .
At this time, when the replacement of the component supply unit 98 of the first component supply table 95 is not completed, the first component supply table 95 is moved after waiting for the input of the completion of the replacement. The replacement of 98 is normally completed before there are no electronic components in the second component supply table 99, and the CPU 170 replaces the first component supply table 95 with the second component supply table 99 and immediately shifts to the work area. It can be moved, and the mounting of electronic components will be performed continuously without stopping.

After mounting such electronic components on a predetermined number of printed circuit boards, when mounting the electronic components on different types of printed circuit boards, as shown in FIG.
The tables are automatically exchanged according to the order shown in the flowchart of FIG. The mode accompanied by this automatic setup change is the second mounting mode. At this time, for example, the first component supply table 95 is in the work area and is in operation, and the supply of the electronic components by the first component supply table 95 completes the mounting of the electronic components on the predetermined number of printed circuit boards. In the event of the occurrence, the operator switches the mode changeover switch to the automatic setup change mode, and at the same time, the operator inputs data indicating the type of the printed circuit board to be mounted next.
Enter from. Further, the component supply unit 98 of the second component supply table 99 which has been evacuated to the evacuating area is replaced with one having electronic components for a printed circuit board to be mounted next,
When the replacement is completed, enter the set completion. When the type of the printed circuit board to be mounted next changes, the type or number of electronic components to be mounted and / or the size of the printed circuit board also changes. In either case, it is possible to switch to the automatic setup change mode. For example, even if a predetermined number of printed circuit boards are mounted and the automatic setup change is completed, the second component supply table 99 in the retreat area is prevented from moving until the set completion is input. ing.

If the printed boards to be mounted next have the same size and only the type or number of electronic components to be mounted are different, it is only necessary to switch the tables and set the number of mounted electronic components. When the completion of setting the component supply unit 98 to the second component supply table 99 is already input at the time of completion, the table is replaced immediately after the automatic setup change for changing the electronic component mounting program is performed. Then, the electronic components are mounted on the next printed circuit board.

When the printed boards to be mounted next have different sizes, the display device 194 notifies the operator based on the input of the type of the printed boards and the setting is made. After the mounting of the number of sheets is completed, in addition to changing the program, automatic setup change including automatic position adjustment of the sub-positioning member 38 in the substrate supporting device 16 is performed. After receiving the notification from the display device 194, the operator operates the handle 54 after the automatic setup change and operates the widths between the conveyor belts 40 and 42 of the substrate loading device 12 and the substrate unloading device 14 and between the guide plates 44 and 46. The width between the guide bars 32 and 30 is adjusted, and after completion, the adjustment completion is input. If the setting of the component supply unit 98 in the second component supply table 99 has already been completed before the completion of the adjustment, the tables are replaced after the above setup change is completed, and the electronic components are mounted. Be seen. If the setting of the component supply unit 98 is not completed, the table is replaced after the input of the completion of the setting is performed, and the electronic components are mounted.

As is clear from the above description, the input completion device for inputting the end of the component unit set of the operation device 172 constitutes the preparation completion detecting means. In the part shown in FIG. 11 among the programs for the three component mounting modes stored in the ROM 174, the part for detecting the mounting completion of the set number constitutes the supply end detecting means, and The automatic setup change means is configured by the automatic setup change and the table change being performed when the mounting is completed, and the table change is not performed unless the end of setting is input. Table replacement prohibition means is configured.

Another mode which can be executed by this mounting apparatus is that there are many kinds or a large number of electronic parts to be mounted on the printed circuit board, and only one of the first table 90 and the second table 92 supplies necessary parts. Unit 9
It is not possible to mount all 8 and both tables 90, 9
This is the mounting mode in the case of mounting in two. In this case, the first and second component supply tables 95,
99 is regarded as one component supply table and is alternately moved to the work area so as to supply the electronic components in the mounting order to the printed circuit board. The component supply units are mounted on the tables 90 and 92 in the mounting order. By doing so, the component supply tables 95 and 99 need only be replaced once when the electronic components are mounted on one printed circuit board.

As is clear from the above description, in the mounting apparatus of this embodiment, the component supply unit 98 is mounted when the types or the number of electronic components to be mounted on the printed circuit board are not large in each of the tables 90 and 92. The size is sufficiently large, and the size may be smaller than that in the case where a table is formed on the assumption that there are many types or numbers of electronic components. Therefore, the operation responsiveness of the first and second component supply tables 95 and 99 is good, and the first and second component supply tables 95 and 99 can be moved at a high speed, so that the work efficiency can be improved and the movement start,
The vibration generated at the time of stoppage is small, the electronic parts are less likely to tilt or change their postures, and the effect of reducing electronic component pick-up errors by the component mounting device 18 is obtained.

Further, in the first and second mounting modes, while one component supply table is in the work area and supplies components, the component supply unit 98 of the other component supply table in the retreat area is supplied. Since the replacement can be performed in parallel, the setup replacement can be completed in a short time when the electronic parts are used up, and the operation rate of the mounting apparatus can be improved.

In the above embodiment, the feed screw 1
52 and 154 are dedicated drive motors 156 and 15 respectively.
Although it is designed to be rotated by means of 8, the transmission of the rotation of the drive motor is switched by a clutch so that both drive screws 152, 154 are driven by one drive motor.
It is also possible to rotate.

Further, the table guide device and the table moving device respectively include a guide rail 150, a feed screw 152,
It is not limited to the one constituted by 154 and the drive motors 156, 158, various forms can be adopted, and the component supply unit is not limited to the one in the above embodiment. Although not exemplarily illustrated, the present invention can be carried out in various modified and improved modes based on the knowledge of those skilled in the art.
