It is arranged. In FIG. 4, reference numeral (41) is a CPU, and R is in accordance with the program stored in the ROM (42).
Based on the data stored in the AM (43), various operations relating to component mounting are controlled. The CPU (41) has an index motor (46), a Y-axis motor (2), and an X-axis, which are drive sources for intermittently rotating the rotary table (13) via an interface (44) and a drive circuit (45). Motor (4) and supply base drive motor (9)
Etc. are connected.

A CRT (48) for displaying a screen for operation is further connected to the interface (44), and a touch panel is formed on the screen of the CRT (48). The RAM (43) stores mounting data as shown in FIG. 5, component placement data as shown in FIG. 6 and component library data as shown in FIG.

The mounting data is different for each type of printed circuit board (6) on which the component is to be mounted, and is stored in the RAM (43) for each type of printed circuit board (6). Reel number for each step number shown,
X data (column labeled "X"), Y data (column labeled "Y"), and θ data (column labeled "θ") are stored. The reel number is a number indicating the arrangement position of the component supply device (8) on the supply base (7), and is assigned a number corresponding to the position of the mounting hole (34). ) The reel number of the mounting position is the chip part (5) by the suction nozzle (14).
Is the reel number of the position where is sucked. The X data and the Y data represent XY position coordinates on the printed circuit board (6) where the chip component (5) should be mounted, and the θ data indicate the θ direction in which the chip component (5) should be mounted, that is, the sucked chip component.

The component placement data is printed circuit board (6).
Which are stored in the RAM (43) and are paired with the mounting data, and how the component supply device (8) is arranged on the supply table (7). It indicates whether or not it has been done. The component arrangement data and the mounting data are collectively referred to as NC data, which is named for each type of printed circuit board (6). The component placement data stores a component ID indicating the type of the component (5) supplied by the component supply device (8) for each reel number.

The part library data is the part ID.
It is created for each and stored in the RAM (43), and the work to be performed by each device of each station in order to mount the chip component (5) of the relevant component ID on the printed circuit board is performed on the component (5). Various types of data are stored so that they can be controlled together. For example, when the component X size and the component Y size are the sizes of the chip component (5) in the XY directions, and the recognition device (16) recognizes that the size is different from the size by a predetermined allowable value or more. Used, for example, to determine that they are different types of parts (5).

When the CPU (41) reads the reel number for each step number from the mounting data, it reads the component ID of the same reel number of the component arrangement data, reads each data of the relevant component ID of the component library data, and performs necessary control. It is a thing. The rotary table (13) is intermittently rotated by an index motor (46) driven by an index motor (46), but it takes a certain amount of time to perform the work in each station. The rotation speed of the motor (46) is adjusted so that the time required for each intermittent rotation, which is the time from one station to the next station, is the predetermined time.
1). The time required for this one intermittent rotation is called the cycle time, but there are various determining factors (see each speed data in FIG. 7), the time required for the suction in the suction station, and the component recognition device (16). Head rotation device (1
7) the time required for angular positioning, the time for moving the XY table (3) to move the printed circuit board (6) to the position indicated by the mounting data, and the position of the reel number also indicated by the mounting data. Because of the movement, there is a time for the supply table (7) to move, and these times also vary depending on the component type. Therefore, the cycle time is determined according to the one that takes the longest of these factors, and the index motor (46) is driven at a speed that is the cycle time.
The component library data in the RAM (43) stores velocity data for determining the cycle time for each work for each component type. When the time required for each work is short, the speed data which is the shortest cycle time for moving at the maximum speed determined by the capacity of the index motor (46) is stored. However, regarding the cycle time due to the movement of the supply table (7) and the XY table (3), even if the respective maximum speeds are stored in the RAM (43) and moved at the maximum speeds, there are other factors such as those shown in FIG. When the CPU (41) determines that movement is not possible during the cycle time, calculation is performed to lengthen the cycle time and the actual operation is controlled.

In the present embodiment, the cycle time of each step number is assumed to be the time from the start of rotation of the rotary table (13) to the start of the next intermittent rotation including the time during which the rotation is stopped, X for each step number operation
The Y table (3) and the supply table (7) are moved while the rotary table (13) is rotating, and while the rotation is stopped, the movement is stopped for component suction and mounting C
It is controlled by the PU (41).

The RAM (43) further defines an upper limit of the cycle time, that is, a mounting speed upper limit memory (44) as a uniform time storage means for determining the upper limit of the speed of the rotary table (13), and the mounting speed upper limit memory. (44)
There is provided a mounting speed upper limit function selection memory (45) as a function designation storing means for deciding whether to disregard as invalid or to use the value of this memory (44) as valid.

The electronic component automatic mounting device is one of the lines for assembling the printed circuit board (6). At the beginning of the line, a screen printing machine for printing paste solder on the substrate (6), an adhesive agent. An adhesive applying device for applying a solder is placed as an upstream device, and a reflow furnace for soldering is placed as a downstream device. The operation will be described below with the above configuration.

First, the speed data as work time of each work is set for each component type, and RA as work time storage means is set.
The operation of storing in M (43) will be described. That is,
When the power is turned on, the initial screen shown in FIG. 8 is displayed on the screen of the CRT (48), and the data edit shown by the double frame and the switch shown in FIG. The library screen is displayed.

Next, the part ID of the part type to be set on the screen is input by an input key (not shown) (may be displayed on the screen or may be displayed by calling another screen). By pressing the switch section displayed as setting,
It becomes possible to edit the part library for the part ID, and by pressing the page feed switch part, the screen of FIG. 10 on the third page is displayed, and the switch part on the right side of the head suction display of the mounting data is pressed. By Figure 10
As shown in, "Mounting data head adsorption" in the lower frame
Is displayed, and 0.14 seconds and the speed data of the head suction work are displayed by operating the right ten key, and 0.14 seconds are set and stored by pressing the setting switch. Head suction is a work in which the supply table (7) moves and the mounting head moves up and down to take out the component (5). The time required for the component ID is 0.14 seconds. It is set.

Similarly, if the speed at which the rotary table (13) rotates with this type of part is this speed,
1.50 seconds, which is speed data for the highest rotation speed that does not cause misalignment of parts, is set for head transport. The nozzle rotation speed data shows that the rotation when the head (15) is rotated and the chip part (5) is swung in the θ direction is 1 more than the maximum rotation speed of the head (15).
It is set that 0% deceleration is necessary, and it is calculated and determined by the time required for the rotation angle amount when the head (15) is rotated at the speed.

Since the recognition processing requires a cycle time of 0.25 seconds, the speed data is set to 0.25 seconds. In this way, the RAM (43) as a working time storage means
The speed data is stored as the working time for determining the cycle time. In this way, the next part ID
When it is desired to set the speed data for, the page is returned to FIG. 9, the component ID is designated, and the same process is performed.

It is not necessary to change the setting after the initial setting, but the same operation is performed when the setting is desired to be changed. As an example of when you want to change the setting, if the work speed of the screen printing machine and the adhesive coating device is slow and the electronic component automatic mounting device waits for the board, you may want to lower the mounting speed. When, for example,
The cycle time of 0.14 seconds is 0.2
By lowering the speed to 5 seconds, the rotation speed of the rotary table (13) may be reduced to the same level as the speed of other devices.

By doing so, the rotary system of the rotary table (13) and the vertically moving mechanism such as the mounting head (15) are slowed down, vibration is reduced, and the life of the drive system is extended. However, in such a case, the cycle time can be easily reduced by doing the following.

That is, when the switch section for production operation is pressed on the initial screen of FIG. 8 and the submenu of FIG. 11 is displayed via the production operation screen (not shown) and the switch section for operation method is pressed, The operating method setting screen is displayed. On the screen, when you press the switch part for specifying the maximum mounting speed,
The mounting speed upper limit designation screen of No. 3 is displayed, and by pressing the switch portion on the right side of the function selection in the upper column, it is possible to select whether or not to specify the mounting speed upper limit designation function. As shown in, two switch parts of "specify" and "not specify" appear, and the function designation is selected by pressing the designation key and the setting key, and the fact that the designation is made is stored in the function selection memory (45). It

Next, when the switch portion on the right side of the speed designation in the upper column is pushed on the screen, the screen of FIG. 14 is displayed and the cycle time upper limit memory is set by operating the ten keys to set 0.25 seconds. 0.25 seconds is stored in (44). Next, the operation of automatic driving in the state set as above will be described.

The CRT (48) is operated on a screen (not shown) to start the automatic operation of component mounting of the electronic component automatic mounting apparatus. First, the CPU (41) shows the cycle time at each work station of the component (5) that is or is being adsorbed by each mounting head (15) according to the flowchart of FIG. The component type and work are specified based on the component arrangement data shown in FIG. 6, and the velocity data is read from the component library data shown in FIG. 7 for each head. The speed data are compared with each other. When the part with the part ID “C1608” in FIG. 7 is adsorbed and held by one of the heads (15), the speed data of the head transport is 1.50 seconds. Since it is the slowest, this speed data is used by the CPU (4
1), and next, the fact that there is a function designation is stored in the mounting speed upper limit function selection memory (45).
Compared with 0.25 seconds of wearing speed upper limit memory (44),
It is decided to rotate the rotary table (13) at the selected cycle time of 1.50 seconds.

Next, the operation after the above determination will be described. First, the CPU (4
1) of the cycle time of the rotary table (13) driven by the index motor (46) under the control of 1).
The supply table (7) moves along the linear guide (12) by the rotation of the ball screw (10) by the rotation of the motor (9) in accordance with the intermittent rotation of 50 seconds, and the reel of the step number in the mounting data of FIG. The component supply device (8) arranged at the number moves to the suction station and stops.

Next, the chip components supplied by the component supply device (8) by the already selected suction nozzles (14) of the mounting head (15) stopped at the suction station by the rotation of the rotary table (13). (5) is adsorbed. Next, in the mounting head (15) which has reached the recognition station due to the rotation of the rotary table (13), the displacement of the chip component (5) sucked by the suction nozzle (14) is recognized. In this case, the CPU (41)
Reads various data of the component ID from the component library data of the component ID (there are data as shown in FIG. 7), and confirms that the components are not of different types based on the component X size, the component Y size, and the size allowable value. The position shift is recognized, for example, by checking. This recognition may be performed within 1.50 seconds.

Next, at the angle correction station, the head rotation device (17) sucks by an angle amount obtained by adding the angle amount for correcting the angular deviation recognized in the recognition station to the θ data of the mounting data. The CPU (41) rotates a θ-axis motor (not shown) so that the nozzle (14) is rotated. This operation may also be performed within 1.50 seconds.

Next, in the mounting station, the positional deviation recognized by the recognition device (16) is corrected and the Y table (1) and the XY table (3) are rotated by the motors (2) and (4). By moving in the XY directions, the chip component (5) is mounted at the position (X1, Y1) on the printed circuit board (6). This operation may also be performed within 1.50 seconds. Next, when the CPU (41) compares the speed data for each work of each head (15) in the next intermittent rotation, the highest speed data of 0.14 seconds can be set as the cycle time. Since the function specification is stored in the mounting speed upper limit function selection memory (45), the upper limit memory (44)
The cycle time is compared with the 0.25 seconds stored in the above, and it is determined that the cycle time is set to the late 0.25 seconds, and the same operation as described above is performed in each station.

Next, the mounting speed upper limit function selection memory (4
When the function selection is stored in 5), the speed data for each work of each head (15) is C in the next intermittent rotation.
When the PU (41) can set the cycle time to the highest speed data of 0.14 seconds, no comparison is made with the memory (44) and the rotary speed is set to 0.14 seconds which is the highest speed. The table (13) is rotated,
The work at each station is performed during this period. When the designation is again made on the screen of the CRT (48) after the designation is stopped in this way, the memory 0 is stored in the memory (44).
If 25 seconds is stored and the conditions of the working time of the other devices on the line are the same as those of the previous one, this 0.25 second can be used again and there is no need to reset.

[0040]

As described above, according to the present invention, since the work time to be delayed can be set and stored as a uniform time, it is not necessary to set and store the work time for each component type and each work type. Easy to operate. Further, by making it possible to specify whether or not to use the uniformly stored work time, the previously set uniform time can be retained, and more flexible operation can be performed.
