By turning the knob 73a of the adjusting screw 73 to adjust the adjusting screw 73 to the width of the printed circuit board, one side of the printed circuit board conveyed by the conveyor 71 is pushed until the slide portion 72 comes into contact with the adjusting screw 73. The other side surface is aligned by the slide portion 72, and the printed circuit board is positioned with reference to one end surface.

An operation example of such a configuration will be described. A printed circuit board to be printed is supplied manually or by a robot hand onto the substrate suction jig 25 raised to the substrate supply height by the Z-direction position adjusting means 23 of the backup unit 20. And the operation control 13
By pressing the start switch, automatic operation is started and the following correction of the warpage of the printed circuit board, recognition of the printed board reference mark, recognition of the screen reference mark, alignment of the printed board with the screen 31, printing on the printed board, A series of operations for discharging the printed circuit board are performed.

First, the operation of correcting the warpage of the printed circuit board will be described. The printed board on the board suction jig 25 is lowered by the Z-direction position adjusting means 23 of the backup unit 20. Then, the correction plate 61 is moved onto the printed board on the board suction jig 25 by the Y-direction position adjusting means 63 of the warp correction unit 60. Next, the backup unit 20
The printed board on the board suction jig 25 is raised again by the Z-direction position adjusting means 23. As a result, the printed board is sandwiched between the correction plate 61 and the board suction jig 25, and is corrected into a flat shape by the elastic force of the leaf spring 61a.

In this state, the Y clamp 27 and the X clamp 26 of the backup unit 20 are closed in this order, and the reference positioning of the printed circuit board is performed.

0 X direction position adjusting means 42 and Y direction position adjusting means 4
3, the camera 41 moves in the X direction and the Y direction, and recognizes, for example, two reference marks at diagonal corners of the printed board on the board suction jig 25. The position of the fiducial mark is stored in advance in a storage medium such as a Memory Stick (registered trademark), and the position of the fiducial mark is read out and the camera 41 is moved by inserting the storage medium into the printer body. To Thereafter, the printed circuit board on the substrate suction jig 25 is lowered by the Z-direction position adjusting means 23 of the backup unit 20, and the camera 41 returns to the origin by the X-direction position adjusting means 42 and the Y-direction position adjusting means 43 of the camera unit 40. . From the above,
The operation of recognizing the reference mark on the printed circuit board ends.

Next, the operation of recognizing the reference mark on the screen 31 and the operation of aligning the printed board with the screen 31 will be described. The screen 31 is moved onto the printed board on the board suction jig 25 by the Y-direction position adjusting means 33 of the screen unit 30. At this time, since the print head unit 50 is connected to the screen unit 30 by the connection switching cylinder 58 of the print head unit 50,

Thereafter, the squeegee 51 attached to the print head 52 of the print head unit 50 moves together with the camera unit 40 by rubbing on the screen 31 surface at one end side of the L-shape by the Y direction position adjusting means 43 of the camera unit 40, 3
The cream solder previously placed on one surface is printed on a printed circuit board.

After the printing, the squeegee 51 swings and switches to the other end of the L-shape, and is attached to the print head 52 of the print head unit 50 together with the camera unit 40 by the Y-direction position adjusting means 43 of the camera unit 40. The squeegee 51 moves in the opposite direction to the above while rubbing on the screen 31 surface at the other end of the L-shape, and scrapes the cream solder remaining on the screen 31 surface. When the squeegee 51 reaches the origin position, the squeegee 51 swings again and switches to one end of the L-shape. Then, the print head unit 50
Print head unit 50
And the camera unit 40 are disconnected, and the print head unit 50 and the screen unit 30 are connected.

Thereafter, the print head unit 50 returns to the original position together with the screen unit 30 by the Y direction position adjusting means 33 of the screen unit 30. By the above operation, even if the print head unit 50 itself does not have a driving device, the target moving operation can be performed by switching the connected party for each necessary moving operation. Then, the Z-direction position adjusting means 2 of the backup unit 20
3, the printed board on the board suction jig 25 is lowered to the board transfer height, and the screen 31 returns to the origin position by the Y-direction position adjusting means 33 of the screen unit 30.
Thus, the printing operation on the printed circuit board is completed.

Next, the discharging operation of the printed circuit board will be described. The board sending means 44 is moved to above the center rear end face of the printed board by the X direction position adjusting means 42 and the Y direction position adjusting means 43 of the camera unit 40, and the center rod of the board sending means 44 is lowered. Then, the printed board is moved to the discharge conveyor unit 70 while the center rod of the board sending means 44 presses the center rear end face of the printed board by the X-direction position adjusting means 42 of the camera unit 40.

At this time, since the belt of the conveyor 71 of the discharge conveyor unit 70 is rotating, the printed circuit board moves on the belt of the conveyor 71. Then, when the printed board reaches the position of the board detection sensor provided on the conveyor 71, the belt of the conveyor 71 stops rotating, and the slide board 72 of the discharge conveyor unit 70 aligns the printed board. The printed circuit board waits on the conveyor 71 until there is a board request signal from the mounting machine in the next step. Thus, the operation of discharging the printed circuit board is completed.

According to such a printing machine, it is not necessary to provide a drive device necessary for the operation of each movable portion for each movable portion. For example, a drive motor, a drive transmission device such as a ball screw and a timing belt, and a control amplifier are used. Because it can be reduced, cost, weight and space can be reduced accordingly. Further, since the mechanical mechanism is simplified, assembling becomes easier and trouble during operation can be reduced.

Although the printing press of the above-described embodiment is configured to be operable with a household power supply (100 V) and compressed air, if the portion operated by an air cylinder is operated by using a solenoid, Household power supply (100
A printing machine operable only by V) can be configured.

An image recognizing device that has a plate holding unit that positions the substrate and an imaging unit that images the substrate or the printing plate, and moves the imaging unit in the X direction and the Y direction to recognize the position of the substrate or the printing plate. A processing unit, connected to the plate holding unit, moved in the Y direction, positioned above the substrate held by the substrate holding unit, disconnected from the plate holding unit, and connected to the image processing unit. Then Y
And a conductive material applying means for applying the conductive material to the substrate via the printing plate, wherein each of the driving means for moving the plate holding means and the image processing means is provided with the conductive material applying means. A printing press characterized by moving the printing press. 2. The printing press according to claim 1, further comprising a connection switching unit that switches connection between the plate holding unit and the image processing unit. 3. The printing press according to claim 1, wherein the printing press can be placed on a desk and can be operated by a household power supply and compressed air.
