This includes a screen 50 having a predetermined pattern of holes 51, a work table 200 positioned at the bottom of the screen 50, and a scraper 60 for reciprocating the paste applied on the screen 50. Equipped.

Such a printer passes a printing paste (not shown) from the screen 50 to a substrate (not shown) seated on the work table 200 and prints the desired pattern.

In addition, the work table 200 is to be moved along the guide groove 70 to be located or withdrawn to the printing position directly below the screen 50.

On the other hand, as a characteristic configuration of the present invention, there is provided an adjusting device for adjusting the printing position so that the substrate seated on the work table 200 exactly matches the printing pattern of the screen 50.

3 to 5, through holes 101 are formed on an upper surface thereof, and the work table 200 is slidably supported at an edge of the through holes 101 and guide holes are provided on both sides of the bottom surface. A fixed table (100) having a pair of vertical walls (110, 120) formed with 111 and 121; A movable body (10) (20) coupled to each of the guide slots (111) (121) so as to be slidable and employing spherical bearings (11) (21); A moving shaft 30 coupled to each of the spherical bearings 11 and 21 so as to be movable and having screw portions 31 and 32 formed at both ends thereof; A movable block 210 having an upper surface fixed with the work table 200 and fixed portions 211 and 212 fixed to the movable shaft 30 on the lower surface thereof; First and second adjustment knobs 310 and 320 which are screwed to both ends of the moving shaft 30 and whose ends are in contact with and separated from each of the vertical walls 110 and 120; Moving rods 331 coupled to the respective moving bodies 10 and 20 through the holes 112 and 122 of the vertical walls 110 and 120 communicating with the guide holes 111 and 121, respectively. Third and fourth adjustment knobs 330 and 340 having a 341; Springs (131, 132) connected between the fixed table (100) and the moving block (210) such that the moving block (210) is pulled toward the third and fourth adjusting knobs (330, 340); And fixing means for fixing the substrate 500 to the work table 200.

As illustrated in FIG. 5, guide jaws 111a and 121a are formed in the guide slots 111 and 121 to prevent separation of the movable bodies 10 and 20.
The guide holes 111 and 121 are places where the moving bodies 10 and 20 are coupled to each other, and the outer surfaces of the moving bodies 10 and 20 in contact with the upper and lower surfaces of the guide holes 111 and 121 are mutually opposite. It has a corresponding shape.
However, it is not necessary to necessarily have the shape of the outer surface of the moving body 10, 20 in contact with the upper and lower surfaces of the guide long hole (111) 121.
In the embodiment of the present invention, the upper and lower surfaces of the guide slots 111 and 121 are formed as concave grooves, so that the edges of the concave grooves are guide jaws 11a and 121a.

As shown in FIG. 4, a plurality of suction holes 201 are formed in the work table 200, and the suction holes 201 are formed between the work table 200 and the movable block 210. ) Is formed in communication with the vacuum chamber 202, and has a structure in which a suction pipe 220 for exhausting air from the vacuum chamber 202 is connected to the movable block 210.

In addition, the third and fourth adjustment knobs 330 and 340 are formed with a display unit for indicating the moving distance of the moving rods 331 and 341, and used a micrometer capable of precisely moving the distance.

The printing position adjusting device as described above is used as follows.

First, the substrate 500 is placed on the work table 200 and the air is exhausted through the suction pipe 220 to fix the substrate 500 to the work table 200 by vacuum suction.

Subsequently, as shown in FIG. 4, the work table 200 is placed in the printing position while the transparent paper 600 is placed on the surface of the substrate 500 and both ends of the transparent paper 600 are fixed to the work table 200. The substrate 600 is moved to print on the transparent paper 600, and the position of the substrate 500 to be printed is adjusted in accordance with the pattern printed on the transparent paper 600 while the work table 200 is drawn out from the printing position.

6 and 7, the adjustment operation in the X direction moves the work table 200 to the left and right (X direction) while adjusting the first and second adjustment knobs 310 and 320.

At this time, to move to the left, the second adjusting knob 320 is unscrewed from the moving shaft 30, and if the opposite first adjusting knob 310 is screwed to the moving shaft 30, the moving shaft 30 is The moving block 210 and the work table 200 fixed to the moving shaft 30 while being moved to the left side are moved together to the left side.

In addition, when the substrate 500 is moved in the vertical direction, when the third and fourth adjustment knobs 330 and 340 are rotated together at the same rotation speed, the work table 200 moves in the vertical direction (Y direction). Will be.

Also, when only one of the third and fourth adjustment knobs 330 and 340 is rotated, the work table 200 is tilted in the θ direction as shown in FIG. 7.

For example, as shown in FIG. 7, when the third adjustment knob 330 is rotated in the clockwise direction, the moving rod 331 enters the third adjustment knob 330 and guides the movable body 10 to the guide hole ( 111). At this time, since the moving shaft 30 is supported by the spherical bearing 11, the movable shaft 30 can be inclined in the θ direction and rotates around the spherical bearing 21. In addition, since the third and fourth adjustment knobs 330 and 340 are adopted as micrometers, the position adjustment can be precisely performed.

As described above, when the work table 200 is moved while the first and second adjustment knobs 310 and 320 and the third and fourth adjustment knobs 330 and 340 are rotated, the movable body 10 and 20 are moved. The guide jaws 111a and 121a of the guide slots 111 and 121 may be stably moved without being separated from the guide slots 111 and 121.

In addition, since the moving block 210 is elastically supported by the fixed table 100 by the springs 131 and 132, the moved position can be stably maintained.

As described above, the first and second adjustment knobs 310 and 320 are used to adjust the position in the X direction, and the third and fourth adjustment knobs 330 and 340 are used to adjust the work table in the Y and θ directions. While adjusting the position of the substrate 500 while moving the 200 to the printing position printed on the transparent paper 600, the transparent paper 600 is removed and the work table 200 is directly below the printing position of the screen 50. The printing is performed to perform the actual printing on the substrate 500.

The printing position adjusting device as described above allows the user to secure the reliability of the product by allowing the user to accurately and accurately adjust the printing position on the substrate 500.

The present invention as described above is not limited to the above embodiments without departing from the spirit and scope of the present application can be practiced with a number of modifications.

The present invention as described above enables the position of the substrate to be adjusted in the left and right directions by the first and second adjustment knobs, and the position in the up and down direction by the third and fourth adjustment knobs. By adjusting any one of the third and fourth adjustment knobs, it is possible to adjust the direction inclined with respect to the Ｘ-Ｙ plane so that it can be printed accurately at a desired position of the substrate, and the adjustment work Simplify

In addition, by employing the third and fourth adjustment knobs as micrometers, it is possible to precisely control the adjustment of the printing position.
