(57) rotates, and the printed circuit board (20) is conveyed.
You. Gear drive pulley by rotation of supply belt (57)
(60) is rotated, the drive gear (62) is rotated,
The supply gear (31) is driven via the transmission gear (63).
You. As a result, the pulley (28) axially attached to the gear (31).
Is rotated, the chuck belt (30) is rotated, and the supply belt is rotated.
Transports the substrate (20) transported to the rack (57).
You. The supply and transfer operation of the substrate (20) is started.
Then, the X camera drive motor (127) and the Y camera drive
The dynamic motor (131) rotates to move the chuck (5) in the X direction.
A position for stopping the center of the substrate (20) at the center position, that is,
From the camera origin position stored in the RAM (230)
The suction jig position tee described above is added to the distance data to the standby position.
Taking into account the offset data obtained by the
The stopper pin (139) moves to the shifted position. And
The stopper cylinder (136) is activated and the stopper pin
(139) is lowered. In this way, the printed circuit board (20)
When transported to the chuck belt (30), the substrate
(20) is stopped by contacting the stopper pin (139).
And the substrate sensor (140) detects the substrate (20)
According to this detection signal, the CPU (229) causes the supply-side motor
(49) is stopped and the rotation of the chuck belt (30) is stopped.
Stop. Next, suction and recovery is performed by a vertical moving means (not shown).
The tool (41) is raised and the substrate on the chuck belt (30) is raised.
Adsorb (20),FIG.Chuck indicated by the two-dot chain line

You. Next, the board (2) by the recognition camera (12)
0) position recognition is performed. That is, the X camera drive motor (127) and
Recognition camera by rotation of Y camera drive motor (131)
(12) on a positioning mark (not shown) of the substrate (20)
And the position of the substrate (20) is recognized. And ma
After the mark recognition, the camera (12) returns to the origin position. This recognition
Result and location of screen board (144) already recognized
Based on the recognition result, the screen plate (144)
The substrate (20) is located at the center of the screen plate (144).
The XY-θ table (87) should
Of the X guide rail (9) in the X direction by the rotation of the motor (94).
The rotation of the Y motor (97) along 3) causes Y in the Y direction.
Screen plate moving along guide rail (100)
(144) Stop at the bottom. Thereafter, the rotation of the θ motor (101)
The θ table (90) is in the θ direction with the θ support shaft (106) as a fulcrum.
And the substrate (20) is opposed to the screen plate (144).
It is positioned at the position where it should be positioned. Next, the screen plate (144) is screened.
Near the substrate (20) by driving the vertical motor (180)
Is lowered. Thereafter, the squeegee (175) is moved.
The printing operation of the paste solder (178) on the substrate (20)
The printing operation will be described. The print motor (168) rotates, and the drive
Ri (170), driven pulley (171), squeegee belt
The squeegee base (167) is at the origin position via (172).
It stops at a position immediately before the substrate (20) as shown in FIG. Next, for example, the right squeegee (144)
The print motor is lowered by the operation of the cylinder (177).
(168) rotates and the squeegee table (167) moves.
The squeegee (175) becomes paste solder (178).
Move while imprinting on the substrate (20). Thus, the paste solder (178) pudding
The printing on the printed circuit board (20) is completed. Next, the descending right squeegee (17)
5) rises and moves to the position of FIG. Next, the screen vertical motor rotates, and the screen moves.
Clean plate (144) rises above substrate (20) and separates
You. Next, X on which the printed circuit board (20) is placed
-Y-θ table (87) is for movement in the Y direction and θ direction
Where the substrate (20) can be discharged by the rotation of the table (table).
(At this time, the origin position detection not shown)
Sensor detects that the table (87) has reached the home position.
Then, based on the signal, the print counter (240)
Count "1". ), By the rotation of the X motor (94)
Move to the discharge conveyor section (8) side and change the discharge side gear (32).
Discharge conveyor in the same way as the supply conveyor section (2)
Engage with a gear (not shown) of the section (8). Then, the suction jig (41) is moved down to move the substrate
(20) is placed on the chuck belt (30). This
After the discharge conveyor (8) starts rotating, the chuck
The belt (30) conveys the substrate (20) and discharges it.
Section (8), and the discharge conveyor section (8)
0) to the downstream device. Next, the rotation of the X motor (94) causes X-
The Y-θ table (87) is located on the side of the supply conveyor (2).
The supply gear (31) moves and the supply conveyor moves in the same manner as described above.
Engage with the transmission gear (63) of the part (2). And supply
The side motor (49) rotates and the supply belt (57)
The substrate (20) is transported and the substrate is placed on the chuck belt (30).
(20) is transferred. Then, in the same manner as described above, the substrate (20)
Fixed and positioned below screen plate (144)
Is Then, the screen plate (144) descends and slides.
Printing of paste solder (178) by keyage (175)
Is performed, and the print counter (240) is incremented to "2".
It is. Thereafter, the substrate (20) is discharged and the next substrate
The same operation as described above is performed for printing the plate (20). Thus, the number of printed sheets on the substrate (20) is
"AUTO" of the NC data counted by the counter (240)
MATIC CLEANING INTERVAL "
After reaching the set “10” (10 sheets), the substrate (2
0) is discharged by the discharge conveyor section (8).
Cleaning operation of the bottom surface of the cleaning plate (144) is performed.
It is. When the print counter (240) reaches the set value
Cleared to "0". For this automatic cleaning operation
explain about. The substrate (20) printed as described above is
When ejected, the XY-θ table (87)
Moved to the supply conveyor section (2) by the rotation of (94)
Then, it is detected by the table standby position detection sensor (118).
Stop at the exit position. The detection sensor (118) is X
After detecting the -Y-θ table (87), cleaning is performed.
The unit (192) is a cleaning unit motor (195)
Rotation of the belt (194) due to rotation of the X guide rail
To the bottom of the screen plate (144)
Moving. Next, the cylinder (218) is moved up for cleaning.
Squeegee (200) on the bottom of the screen plate (144)
Abut And the cleaning unit motor (195)
Rotate, squeegee (200) paste solder (178)
Hose connected to a vacuum source (20
3) Paste solder (1) with vacuum air through (203)
78) are collected in the collection box (204). When the cleaning is completed,
The squeegee (200) is lowered by operating the damper (201).
Away from the lower surface of the screen plate (144). Next, the cleaning unit motor (195)
Rotates, and the cleaning unit (192)
A cleaning origin detection sensor (not shown) on the part (8) side
Move to the position where is detected. In addition, the printing cow
The counter (240) counts “10” and the CPU (229)
Issues a command to perform an automatic cleaning operation,
The cleaning counter (241) performs automatic cleaning
The number "1" is counted. While the above cleaning operation is being performed
Then, the next substrate (20) is supplied from the supply conveyor (2).
Supplied on the chuck belt (30) and the chuck rail (2).
3) is gripped and fixed in the same manner as described above.
However, the automatic cleaning operation ends and the cleaning origin
The detection sensor detects the cleaning unit (192)
If the XY-θ table (87) is
Moves down the screen plate (144) along the
Then, the substrate (20) is positioned, and the paper is positioned as described above.
Printing of the solder paste (178) is performed. The above operation is repeated for cleaning.
The counter (241) reads “AUTOMATI” of the NC data.
"1" set to "C CLEANING COUNT"
2 "(12 times), manual cleaning
An operation for performing the operation is performed. That is, the cleaning counter (241)
It becomes “12” and the cleaning unit (192) is moved.
When it is detected by the cleaning origin detection sensor,
-The yellow lamp of the light (16) flashes and manual operation is performed by the operator.
