方法に関するものである。[Detailed Description of the Invention] Technical Field This invention relates to a printed wiring printing machine, etc.
The present invention relates to a method for positioning a printing plate, and particularly relates to a method for positioning a printing plate when printing is performed on both the front and back sides of the printing plate, or when printing is performed in two or more times.

などの問題があつた。BACKGROUND ART Conventionally, in a printed wiring printing machine, the positioning of a printing board is generally performed as shown in FIG. That is, positioning claws 2, 3, and 4 are erected on the upper surface of a printed board suction cup (hereinafter referred to as suction cup) 1 that is fixedly provided to a printed wiring printing machine (not shown). Adjacent end surfaces of the printing plate 5 are pressed against the positioning claws 2, 3, and 4. That is, two adjacent end surfaces of the printing plate 5 are used as reference surfaces, and the position of the print pattern is determined with respect to these reference surfaces. However, the end surface of the printing plate 5 during normal processing cannot be said to have a sufficient surface roughness to serve as a reference surface, and even if it is processed with sufficient surface roughness, it will be damaged during etching, cleaning steps, etc. In some cases, the reference surface became rough. For this reason, especially when printing is performed two or more times, there are problems such as a large number of defective products due to poor positioning accuracy, or the need for man-hours to modify the reference surface or the product.

題もあつた。 Furthermore, many of the printing plates 5 are printed on both sides. In this case, in order to use the same adjacent end surfaces as reference surfaces in printing on the front and back sides, positioning claws must be provided separately for front and back printing. In such cases, a method may be used in which two resist pins 6, 6 are set up on the top surface of the suction cup 1, and reference holes 7, 7 are provided in the printing plate 5 for positioning (see Figure 2). . However, due to the material of the printing plate 5, it expands and contracts significantly due to temperature changes, and
Since there are variations in the processing of the reference holes 7, 7, the tolerance between the resist pins 6, 6 and the reference holes 7, 7 is set to be quite large. As a result, quite large positional deviations occurred for some of the substrates 5. Further, when the soldering process is performed first, there is a problem that solder adheres to the reference holes 7, 7, making them unusable as reference holes.

は５〜10粍程度である。 Now, first and second position reference marks 17 and 18 are printed on the printing plate 9 at positions corresponding to both ends of the reference end surface 9a during the first printing process. That is, main reference lines 1 that are orthogonal to each other serve as references for print patterns to be printed in each printing process.
9 and a sub reference line 20 are determined. In addition, main reference line 2
0 is parallel to the X axis, and the sub reference line 20 is parallel to the X axis.
It is set parallel to the Y1 axis and Y2 axis. Then, a straight line sign 1 consisting of one section on the main reference line 19
7, and a polygonal line mark 18 consisting of a straight line based on another section on this reference line 19 and a diagonal line intersecting this at an angle of 45°, are used as the first and second position reference marks 17, 18. This is added to the initial print pattern. The relationship between the polygonal line mark 18 and the sub-reference line 20 is determined such that the sub-reference line 20 intersects both of the base lines of the polygonal line mark 18. Further, the relationship between the two marks 17 and 18 and the printing plate 9 is that the printing plate 9 is located at a position corresponding to both ends of the reference end surface 9a of the printing plate 9,
When the markers 12 and 13 are positioned, both markers 17 and 18 are positioned directly below the line sensors 15 and 16. The width of the lines of the first and second position reference marks 17 and 18 is about 0.2 to 0.3 mm, and the length of the lines is about 5 to 10 mm.

6 detects the position of the linear marker 17 in the direction perpendicular to the X-axis (the position at the bottom of the line) and outputs it as an electrical signal (see FIG. 5). The A/D converter 22 converts this into a digital quantity and inputs it to the computer 24 via the input port 23. The computer 24 compares this input with the correct position of the linear marker 17 (position of the main reference line 19) stored in advance, and adjusts the output port 25 so that the difference becomes zero.
A signal is sent to the step motor 28 of the Y two- axis movement mechanism. As a result, mainly the right end portion of the suction cup 10 moves in the Y2 axis direction, and the linear marker 17 is corrected to the correct position (position on the main reference line 19). At the same time as the above operation, the line sensor 15
detects the position of the base line of the polygonal line mark 18 and compares it with its correct position (position of the main reference line 19).
Drive the step motor 27 of the Y 1- axis movement mechanism,
The base line of the polygonal line mark 18 is corrected to the correct position (position on the main reference line 19) by moving mainly the left end portion of the suction cup 10 in the Y1 axis direction.

Read the height of the diagonal line 8 at the position of the line sensor 15, compare it with the correct height (height on the sub reference line 20) stored in the computer 24, and adjust the height so that the difference becomes zero. The output is output to the step motor 26 of the shaft moving mechanism, and the entire suction cup 10 is moved in the X-axis direction. As a result, the position of the printing plate 9 is corrected, and the main reference line 19 and the sub reference line 20 are brought to the correct position. After this, print patterns for each process are printed.

修正する。 In the above case, printing is performed only on one side of the printing plate 9, but when printing on both sides of the printing plate 9, the following procedure may be performed. That is, wiring to the surface, position reference marks 17, 18
After printing, when the printing plate 9 is turned over and positioned on the suction cup 10, a see-through hole (not shown) is provided on the upper surface of the suction cup 10 facing the position reference marks 17 and 18, and a line sensor is placed directly below the see-through hole (not shown). Line sensors 29 and 30 (FIG. 6) corresponding to 15 and 16 are further provided. Then, the line sensors 29 and 30 read the position reference marks 17 and 18 pointing downward through the see-through holes, and move the suction cup 10 by comparing the positions with the main reference line 19 and the sub reference line 20 stored in advance. and correct the main reference line 19 and sub-reference line 20 on the board 9 to correct positions.

ることができる。 In the above substrate positioning method, even if the position of the printing plate relative to the suction cup 10 changes due to a defect in the reference end faces 9a, 9b of the printing plate 9, the second
Before printing after printing, line sensor 15,1
6 (for double-sided printing, line sensor 15, 1
6, 29, 30) read the position reference marks 17, 18, move the entire suction cup 10, and move the entire suction cup 10 to the printing plate 9.
Finely adjust the upper main reference line 19 and sub reference line 20 to the correct positions. Therefore, since the multi-step printed pattern is automatically correctly positioned for each step, the defective rate due to poor positioning is significantly reduced, and the time required for reworking the reference end faces 9a and 9b and the work time required for positioning are greatly reduced. The process is shortened to improve product quality and reduce costs. In particular, the polygonal line marker 18 consists of a straight line based on a section on the main reference line 19 and a diagonal line that intersects this line at an angle of 45 degrees, and furthermore, the polygonal line marker 18 consists of both the straight line and the diagonal line. Since the sub-reference lines 20 of the print pattern are set so as to intersect with each other, one line sensor 15 can detect the position in both the direction of the main reference line 19 and the direction orthogonal to the main reference line 19. Since the printing plate can be accurately positioned with only two types of movement operations: movement in a direction perpendicular to the main reference line 19 and movement in the direction of the main reference line 19, equipment costs and manufacturing costs can be particularly reduced.

もたらす。Effects As explained above, the present invention provides a first position reference mark that includes a straight line in the direction of the main reference line of the print pattern and a straight line in the direction of the main reference line on the printing plate during the first printing process. and a second position reference mark including a diagonal line that intersects with the second position reference mark, further setting a sub-reference line of the print pattern so as to intersect both the straight line and the diagonal line of the second position reference mark, and then , a printed first position reference mark and a second printed position reference mark.
Based on each straight line in the direction of the main reference line included in the position reference mark, the positions of both marks in the direction orthogonal to the main reference line are detected and stored, and the second position reference on the sub-reference line is detected. Based on the distance between the straight line and the diagonal line of the mark, the position of the second position reference mark in the main reference line direction is detected and the position is stored. When printing for the second and subsequent times, each straight line in the direction of the main reference line included in the first position reference mark and the second position reference mark is read to detect the position in the direction orthogonal to the main reference line of both marks. Based on the memorized position, if necessary, the position is corrected in the direction orthogonal to the main reference line, and furthermore, the position of the second position reference mark on the sub-reference line is adjusted between the straight line and the diagonal line. By reading the distance, the position of the second position reference mark in the direction of the main reference line is detected, and the position in the direction of the main reference line is corrected if necessary based on the memorized position. It is possible to accurately position the printing plate during the printing process throughout the process, improving product quality and reducing the defective rate. Furthermore, since the sub-reference line of the print pattern was determined so as to intersect both the straight line and the diagonal line constituting the second position reference mark, one detection device could detect the second position reference mark. Position detection is possible both in the direction of the main reference line and in the direction orthogonal to the main reference line, and moreover, it only requires two types of movement work: movement in the direction perpendicular to the main reference line and movement in the direction of the main reference line. Accurate positioning of the printing plate is possible, so
This has the excellent effect of reducing work man-hours and significantly reducing costs in terms of equipment and manufacturing.
