A separate conveyor motor 310 is coupled to the conveyor 300 so that the conveyor 300 can be driven and the conveyor 300 can transfer the printed circuit board 1 by the rotation of the conveyor motor 310 .

The printed circuit board 1 conveyed along the conveyor 300 recognizes the printed circuit board 1 and stops moving when it reaches the area where the mask prepared for performing screen printing is disposed, The printed circuit board 1 must be fixed in place. The first plate 100 and the second plate 200 are moved toward the printed circuit board 1 through the gap adjusting unit 600 to fix the position of the printed circuit board 1. [ One end of the gap adjusting part 600 is installed on the first plate 100 and the other end is installed on the second plate 200 to connect the first plate 100 and the second plate 200, The first plate 200 and the second plate 200 may be spaced apart from each other. The first plate 100 and the second plate 200 may be spaced apart from each other by a predetermined distance from the first plate 100 and the second plate 200, The first plate 100 and the second plate 200 may be arranged in parallel to each other such as a second gap adjusting unit 620 connecting the adjusting unit 610 and the other ends of the first plate 100 and the second plate 200. Here, although various configurations can be applied to the interval adjusting unit 600, it is most preferable to use a ball screw whose interval is adjusted by the rotation driving.

A gap adjusting motor 630 is coupled to an end of the gap adjusting unit 600 so that the gap adjusting unit 600 may be rotated by a ball screw and a gap adjusting unit 600 is provided between the gap adjusting unit 600 and the gap adjusting motor 630 And a coupling 640 connecting them is interposed. Accordingly, by the rotation driving of the interval adjusting motor 630, the gap adjusting part 600 is rotated to adjust the distance between the first plate 100 and the second plate 200. The first gap adjusting unit 610 and the second gap adjusting unit 620 are connected to the belt 620 so that the pair of spacing adjusting units 600 are rotated and rotated in the same rotational speed and direction. 650, and a pulley 660 to transmit the power of the gap adjusting motor 630.

The first plate 100 and the second plate 200 are mounted on the opposite surfaces of the fixing plate 400 to clamp the printed circuit board 1. The fixing clamps 400 may be formed as a single long piece along the longitudinal direction, or may have a plurality of blocks. The stationary clamp 400 is configured to directly contact the printed circuit board 1 when the first plate 100 and the second plate 200 move toward the printed circuit board 1 to fix the printed circuit board 1, And functions to clamp the printed circuit board 1 by the tension of the pressurizing pressure adjusting spring 730. At this time, even if the first clamping plates 400 are provided in the first plate 100 or a plurality of the clamping clamps 400 are provided, the second clamping plates 400 are continuously arranged without spaced- It is preferable to arrange them. The fixing clamp 400 may be spaced apart from both the first plate 100 and the second plate 200 as occasion demands.

When the fixing clamp 400 is disposed on at least one of the first plate 100 and the second plate 200 with a spacing space, the flow clamp 500 is disposed in the spacing space. That is, the flow clamp 500 is alternately disposed between the plurality of fixed clamps 400, such as the fixed clamp 400, the flow clamp 500, the fixed clamp 400, and the flow clamp 500.

4A is a view showing a state of the flow clamp 500 when clamping a normally rectangular printed circuit board 1 and FIG. 4B is a view showing a state where the flow clamp 500 is clamped when the printed circuit board 1 having a non- (500) according to an embodiment of the present invention. In the case of the printed circuit board 1, the printed circuit board 1 is formed in a rectangular shape. However, the printed circuit board 1 may have a trapezoidal shape that is not rectangular when the substrate is cut or the printed circuit board 1 is partially changed in shape by various processes. In this case, even if the printed circuit board 1 is clamped by using the fixed clamp 400 arranged in parallel, a region which is not clamped partly due to the shape of the printed circuit board 1 is generated. If the printed circuit board 1 is not properly clamped, the position of the printed circuit board 1 is shifted in the screen printing process, and the pattern of the mask and the printed circuit board 1 is changed, . Accordingly, in order to prevent this, the present invention includes a flow clamp 500 capable of properly clamping the trapezoidal printed circuit board 1.

The flow clamp 500 includes a block-shaped clamp body 510, a rotary shaft 520, and a spring 530 that are alternately disposed between the stationary clamps 400 as shown in Figs. 5A and 5B. The rotary shaft installed in the flow clamp 500 is coupled through the vertical direction of the clamp body 510 and supports the clamp body 510 to rotate. It is preferable that the rotating shaft 520 is protruded at the upper portion of the rotating shaft 520 with a larger diameter than the rotating shaft 520 like a screw head to prevent the clamping body 510 from escaping to the upper portion of the rotating shaft 520 Do. Further, it is preferable that a bearing 540 is inserted between the clamp main body 510 and the rotating shaft 520.

6, a pair of spring coupling holes 511 are formed in the clamp main body 510 along the longitudinal direction on a surface facing the plate on which the clamp main body 510 is disposed, The spring 530 is selectively inserted into any one of the holes 511. The spring clamping holes 511 are not formed in the central region but are formed in the both end regions. When the flow clamp 500 is formed in the central region, the spring clamping holes 511 are formed at both ends of the spring clamping holes 511, The spring 530 is engaged to allow the clamp body 510 to rotate freely.

One end of the spring 530 is coupled to a corresponding plate on which the clamp body 510 is disposed and the other end is coupled to the clamp body 510 so that the clamp body 510 can be clamped according to the shape of the printed circuit board 1. [ Lt; / RTI > When the spring 530 is protruded, the clamp body 510 protrudes toward the direction in which the printed circuit board 1 is arranged with the rotation axis 520 as the center. When the distance between the first plate 100 and the second plate 200 is adjusted through the gap adjusting unit 600, the printed circuit board 1 and the flow clamp 500 are brought into contact with each other, The spring 510 is inserted into the plate while rotating, and the spring 530 is compressed. Since the flow clamp 500 protrudes to the outside as compared with the fixing clamp 400 by the spring 530, the printed circuit board 1 having a trapezoidal outer surface can be easily clamped. The clamp body 510 can be rotated about the axis by the rotation shaft 520 and the spring 530 and can be elastically protruded and inserted so that it can be stably clamped regardless of the angle of the outer surface of the printed circuit board 1 Do.

A clamp support 700 is disposed below the fixed clamp 400 and the flow clamp 500 to support the fixed clamp 400 and the floating clamp 500 as shown in Figs. 7A and 7B. The clamp supporter 700 is vertically penetrated from the upper portion of the clamp main body 510 to the lower portion of the clamp main body 510 to be bolt-nut fastened at the lower portion of the clamp supporter 700. To this end, a screw thread is formed on the lower portion of the rotating shaft 520 and the clamp supporter 700 so that a bolt-nut can be fastened.

The pressing pressure adjusting spring 730 presses the fixing clamp 400 to adjust the amount of the pressing force with the tension adjusting screw 740. The pressing force adjusting spring 730 adjusts the amount of pressure between the first plate 100 and the second plate 200 and the clamp supporting part 700 . When the distance between the first plate 100 and the second plate 100 is increased to release the clamping of the printed circuit board 1 after screen printing, the pressing pressure adjusting spring 730 elastically protrudes again, . A tension adjusting screw 740 is coupled to the end of the pressure adjusting spring 730 and the tension of the pressure adjusting spring 730 can be freely adjusted by the tension adjusting screw 740 according to circumstances.

The first plate 100 and the second plate 200 moving close to each other for clamping the printed circuit board 1 are required to be in parallel with the printed circuit board 1, And includes a linear motion guide 710 and an LM block 720 so that the first plate 100 and the second plate 200 make a linear sliding movement during fixing.

The LM guide 710 has one end coupled to the first plate 100 and the second plate 200 and the other end coupled to the clamp support 700 to guide a moving region when the LM block 720 moves to be. The LM block 720 is installed below the first plate 100 and the second plate 200 so that the first plate 100 and the second plate 200 can be slidably moved along the LM guide 710. That is, when the first plate 100 and the second plate 200 move and clamp the printed circuit board 1, the first plate 100 and the second plate 200 are pressed by the clamping, The plate 100 and the second plate 200 are pushed back by the LM guide 710 and the LM block 720.

In the conventional fixing device for a printed circuit board for a screen printer, the clamps for clamping the printed circuit board are arranged parallel to each other in the longitudinal direction so that the printed circuit board having a deformed shape can not be easily clamped, . In contrast to this, in the present invention, the printed circuit board 1 having a deformed shape can be easily clamped by the flow clamp 500, which rotates and protrudes in the direction of the printed circuit board. Thus, the printed circuit board 1 can be stably clamped Thereby reducing the defective rate. In addition, when the printed circuit board 1 is not introduced straight through the conveyor 300 but flows in a partially crooked state, the flow clamp 500 elastically urges the printed circuit board 1 in a proper position So that they can be searched and moved.
