Position detection method for detecting the coordinates of the reference part on the printed circuit board and the reference part on the base on which the printed circuit board is placed, and using the position Detection method and positioning method of printed circuit board of position detection device. [Prior Art] When a printed circuit board formed on a printed substrate w such as a flexible film is punched out, the C-shaped portion of the outer contour line W1 is trimmed along its end, which is the so-called slim hole w2. High precision is required for punching (see Figure 8). That is, when a plurality of wiring pattern connecting wires are formed at the end of the printed circuit board w surrounded by the trimming hole W2, the entire printed circuit board w is punched out by a conventional punching device including the trimming hole ... Since the punching accuracy around the connecting lead portion is low, a poor connection between the lead portion and the lead portion is prone to occur, resulting in a problem that the reliability of the product is reduced. Therefore, in the prior art (refer to Japanese Patent Publication No. 2662477), an alignment mark is provided near the end of a printed circuit board, and the alignment mark is imaged by an imaging device such as a CCD camera. At the same time, the alignment is performed by image processing. The marked coordinates are detected, and using the detected coordinates as a reference, the trimmed holes at the ends of the printed circuit board are punched by a punch. However, according to the above-mentioned technology, when the end of the printed circuit board and the punch are cleaned at the punch, the angle of the printed substrate or the substrate corresponding to the punch to form the printed circuit board is angled. Correction, so it is necessary to detect the coordinates of at least two alignment marks for each printed circuit board. = m. I want to use two cameras to capture two alignment marks. Therefore, Γ needs to make the field of view wider than that of the same resolution. Although this imaging accuracy has been proposed to provide two imaging devices corresponding to two alignment marks, but when the printed circuit board is small, the interval between the two alignment marks also becomes a small size. Interference may occur between the two cameras. In addition, although it is conceivable that the above-mentioned camera unit is installed obliquely to avoid the problem of interference, in this case, since the image is distorted, high-precision imaging cannot be obtained. In addition, although the problem of moving one imaging device corresponding to two alignment marks may be considered, in this case, since the movement time of the imaging device is required, the coordinate detection time becomes long. [Summary of the Invention] The present invention was developed in view of the above problems, and an object thereof is to provide a method of imaging and detecting each of a plurality of reference parts arranged at minute intervals in a short time with high accuracy without causing multiple imaging devices to interfere with each other. A position detection method of a coordinate of a reference part, a position detection device, and a positioning method of a printed circuit board. In order to solve the above-mentioned problem, the position detection method of the present invention optically divides the image of at least two reference parts into a plurality of images corresponding to each of the reference parts. The image of each of the reference parts is taken as the image of ㈣ = = According to the image processing, it is detected that the reference parts are two, for example, two outer diameter lines of the 修 -shaped trimming of a printed circuit top formed on a printed substrate. The printed circuit board c has an angular top and a plurality of predetermined portions of a mold for die-cutting the printed circuit board from the printed substrate. In addition, the above-mentioned optical segmentation means that the images of the directions 稜鏡 and = are used to divide into multiple images, and are respectively guided in different directions = xi =. A specific example is the use of a prism mirror whose cross section is an isosceles triangle. The image shot by the person towards the side of the mirror is divided into two and four points, and the two images obtained by the division are reflected in different directions, respectively. According to the above-mentioned technical means, the images of the plurality of reference portions are optically divided into a plurality of images corresponding to each of the reference portions, so that the intervals between the reference portions are made to be incident on the corresponding imaging devices in an enlarged manner. The position detection device according to the second aspect of the invention includes optically dividing an image of at least two reference portions of the entrance port into a plurality of images corresponding to each of the reference portions, and respectively dividing the plurality of images obtained by the division into The optical guide device guided by the exit port and a plurality of imaging devices facing the exit port respectively perform image processing on the imaging data obtained by the plurality of imaging devices to detect the coordinates of the reference positions. A position detection device according to a third aspect of the present invention is characterized in that the optical guide device includes a first reflection device that reflects an image of at least two reference portions incident on the entrance port toward one direction, and a first reflection device that reflects the first reflection device. An optical branching device that divides an image into a plurality of images corresponding to each of the reference positions and guides the plurality of images obtained by the division to different directions, and reflects and guides each image divided by the optical branching device The second reflecting means to the exit-entrance port. : In addition, the position detection device of the fourth invention is characterized in that the optical guidance device and the imaging device are relatively moved to move the field of view of the image of each reference part obtained by imaging. The mutual movement of the optical guiding device and the imaging device includes: moving the imaging device in a state where the optical guiding device is fixed; moving the optical guiding device in a state where the imaging device is fixed; and moving the optical guiding device and When both of the imaging devices are moved in the same direction. In addition, the position detection device of the fifth invention is characterized in that there are two reference positions, and the optical guide device and the two image pickup devices are relatively moved by a direction substantially orthogonal to the arrangement direction of the two second reflection devices. , Move the two above-mentioned fields of vision toward the approaching and leaving directions. Further, the position detection device of the sixth invention is characterized in that there are two reference positions, and the optical guide device and the two image pickup devices are relatively moved by a direction substantially parallel to the arrangement direction of the two second reflection devices. , So that one of the two visual field ranges moves in a direction substantially orthogonal to the moving and moving directions, and the other moves in a direction opposite to the moving direction of the visual field range of the one ... In addition, the seventh invention is a printed circuit board positioning method using a position detection device, characterized in that the coordinates of at least two reference positions on the abutment and a plurality of coordinates on the printed circuit board corresponding to these coordinates are detected, 591198 moving one or both of the abutment and the printed circuit board so that the reference position on the ~ printed circuit board and the reference position on the abutment are caused. ♦, [Implementation]

The first reflecting device 12 is a reflecting mirror, which is fixed at an inclination angle of about 45 degrees in the main body housing 11 supported horizontally, and reflects the images of the two reference parts 31a and 31a, which are projected from below, toward the main body housing ^. Rear guide. The first reflecting device 12 may be a prism if it functions in the same manner as described above. The optical branching device 13 is a chirped mirror having a substantially isosceles triangular cross section, and is fixed to the central rear end portion of the main body housing 11 with the top thereof facing the first reflecting device 12 described above. This optical branching device 13 divides an image incident from the i-th reflecting device 12 side into two parts of 45 degrees left and right and reflects it, and guides the two images obtained by the division to the second reflecting device 14. ## The second reflecting device 14 is a so-called top-shaped chime (also called a roof-shaped chime or a reflecting surface chime), which causes an image incident from the incident surface 14a to be sequentially reflected by the two reflecting surfaces 14b and 14c in the chirp Is emitted from the exit surface 14d (see Fig. 3). The angle of the two reflecting surfaces 14b, 14c is 90 degrees, and the angle of the ridge line 14 € of the reflecting surfaces 14b, 14c and the incident surface 14a is 45 degrees. The second reflection device 14 reflects the images obtained by dividing by the optical branching device 13 and guides them to the exit opening 11b and is fixed to the inner sides of the exit openings lib and lib of the main body u, and the two second reflections The devices η and 14 have their incident surfaces 14 a and 14 a facing each other. The function of the second reflection device 14 will be described in detail below. As shown in FIG. 3, when the image p of the character P is incident on the coordinates (di, di,) of the incident surface 14a, it is reflected at the point 14M on the reflecting surface 14b, and becomes clockwise on the χ-ζ plane. Degrees, the image obtained by rotating 45 degrees clockwise on the χ-γ plane. This image P 'is reflected at the point I4cl of the reflecting surface 14c, and becomes an image P "' that rotates 90 degrees clockwise on the χ-z plane and 45 degrees clockwise on the [Y plane" 'D from the exit surface 14d (d. , Do,). However, as shown in FIG. 2, the optical guide device 10 configured as described above will display a character r on the work surface ψχ below the first reflecting device 12: an image H, £ 1 of the character L Incidentally, the reflection device 12 reflects the image r2 and image a perpendicular to the workpiece surface Wx. When these images r2 and € 2 are incident on the optical branching device 13, they are separated into the two characters R and L respectively. The corresponding two images r3 and ^ are reflected. These images r3 and £ 3 go straight in opposite directions in a direction at right angles to the direction of incidence to the optical branching device 13, and are incident on the right second reflection device 14 and the left The second reflection device 14. Since the image Γ3 is reflected to the reflection surface 14b (see FIG. 3) in the right second reflection device 14, it becomes an image r4 that rotates the work surface ^ by 90 degrees in the clockwise direction. In addition, the image € 3 is reflected by the reflecting surface in the second reflecting device 14 on the left The letter L on the surface Wx becomes a counterclockwise image ι · 4 and € 4, which are incident on the left and right camera devices 20 respectively. These camera devices 20 and 20 are CCD cameras, which are respectively close to the two of the optical guide device 10. Each shooting port 11 b, 11 b is arranged. Each camera device 20 is a horizontal moving machine 591 198 (not shown in the figure) which is supported by a combination of a ball screw mechanism, a guide, and a servo motor so as to be horizontally movable in the Π direction. In addition, a display 43 (refer to FIG. 4) is electrically connected to the rear end of each imaging device 20 via the image branch circuit board 41 and the image processing device 42, and two images captured by the two imaging devices 20 and 20 are captured. The images are displayed on the left and right displays 43, 43. ## According to the position detection device A configured as described above, the images of the two reference portions 31a and 31a on the mold 30 are reflected by the first reflection device 12 and the optical branch device 13 second. The device 14 reflects in order to divide it into two images corresponding to each of the above-mentioned reference portions 31a. The divided images are captured by the imaging device 20 and displayed on each display 43. At the same time, the image is processed by the image processing device 42 deal with, The coordinates are detected. At this time, the mold 30 is arranged at an angle to the left and right visual field ranges s and s on the mold 30, or the width between the left and right visual field ranges s and s and the widths of the two reference portions 31a and 31a. For different occasions, moving the two camera devices 20 and 20 horizontally in a direction that is substantially orthogonal to the direction in which the two second reflecting devices 14 and 14 are arranged or / and a direction that is substantially parallel to each other can make the left and right fields of vision The positions of the ranges S and S change. For example, as shown in FIG. 5 (a), the mold 30 is aligned with the left and right visual field ranges s and s on the mold 30 obtained by the two imaging devices 20 and 30. When the clockwise direction is arranged at an angle, and if the widths of the two reference portions 31a and 31a are wider than the left and right visual field ranges S and S, the directions are orthogonal to the arrangement direction of the two second reflecting devices 14 and close to two. Moving the two camera devices 20 and 20 in the direction of the reference part 31a (direction XI in FIG. 1), the field of view S on the right side can be shifted toward the direction of Rxi, and the field of view s on the left side can be changed in the direction of Lxl 12 591198. Bit 'that is to the two fields of view s, s Expanding the pitch direction of the displacement. (Fig. 5 (bl)). — Further, if the two imaging devices 20 and 20 are moved to the left direction (the γ2 direction in the i-th figure) parallel to the arrangement direction of the two second reflecting devices 14:, the left-side visual field range S can be directed to the Ry2 direction (the 5. The lower direction of the figure) is shifted, and the visual field range SL on the left side can be shifted to the Ly2 direction (upward direction of the fifth figure) (figure 5 (cl)). " Yu Yu, the two reference parts 31a, 31a can be respectively located at their positions near the center of the corresponding field of view S, and at the same time, the corresponding positions on the displays 43 and "" are displayed near the center. Reference part 31a. The coordinates of the reference parts 31a and 31a are detected by image processing, and the angle of the die 30 and the punch (not shown in the figure) corresponding to the die 30 or the printing base superimposed on the die 30 as required. Correction of the angle of the material w. The moving direction of the above-mentioned camera device 20 is an example, and the two camera devices can be respectively moved in the desired horizontal direction by the above-mentioned horizontal moving mechanism, and the left and right visual field ranges S and S are respectively oriented and corresponding. The moving direction of the camera device 20 is shifted in the corresponding direction. That is, when the camera device 20 on the right side moves in the XI direction, its field of view S is shifted toward the Rx1 direction. Movement in 2 directions: The field of view S is shifted toward the direction of Rx2, and the movement of the field of view Y of the camera device 20- on the right side is shifted toward the direction of Ryl. The movement of the Y2 direction of the device 20 shifts its field of view s toward the direction of Ry2. 13 The movement of the X1 direction of the left imaging device 20 shifts its field of view S toward the Lx1 direction, and shifts the left imaging device 2 The movement in the direction of 〇 shifts the field of view S toward the Lx2 direction, moves in the π direction of the left imaging device 20, the field of view s shifts in the direction, and moves the Y2 direction of the left imaging device 20, The field of view s is displaced in the direction of Ly2. Next, a procedure for positioning the printed circuit board w on the template 30 (abutment) using the position detection device a configured as described above will be described with reference to FIG. 6. First, as shown in FIG. 6 (a As shown in the figure, the image processing device 42 is used to perform image processing on the two reference portions 31 a and 31 a on the mold 30 on which the printing substrate w is placed, and to detect the image captured by the imaging device 20. 8. Then, the position detection device A is used to detect the 外形 -shaped trimmed shape of the printed circuit board w at a position corresponding to the reference portions 31a and 31a, that is, at the end of the printed circuit board w, which is placed near the mold 30. The coordinates of the two out-angled reference parts wla, wla on the line wl (refer to the figure ...). Then, the conventional conveying mechanism or moving mechanism (not shown in the figure) can be rotated and moved horizontally. Move the printing substrate W or the mold 30 toward the χγ direction or / and the rotation direction, so that the reference portions wla, via and the reference portions 3ia, 3ia coincide, and overlap the printing substrate boundary and the mold 30. The printed circuit board wi ^ is used to punch a trimming hole w2 using a punch (not shown in the figure) (see FIG. 6 (c)). Next, another description of the position detection device of the present invention will be described with reference to FIG. An example 0 591198 The above-mentioned position detection device A is composed of two camera devices 20 and 20 that can be moved horizontally, while the position detection device B is a combination of two camera devices 20 and 20, and the optical guide device 10 can It moves horizontally toward χγ.

Known: According to this position detection device B, the left and right visual field ranges s, s are displaced toward the corresponding direction of the moving direction of the optical guide device 10. That is, when the optical guide device 10 moves in the XI direction, the visual field range S on the right is shifted toward the RX2 direction, and the visual field range s on the left is shifted toward the Lx2 direction. In addition, with respect to the displacement of the optical guide device 10 in the direction, the field of view S on the right is displaced in the direction of Rxl, and the field of view s on the left is displaced in the direction of Lxl. In addition, the movement of the optical guide 10 in the ^ direction shifts the field of view S on the right toward Ry2, and the field of view s on the left shifts toward Ly2. In addition, the movement of the optical guide 10 in the ¥ 2 direction shifts the vision field S on the right side toward the Ryl direction, and at the same time, the field of view s on the left side shifts toward the Lyi direction. The above position detection device A is configured so that the two camera devices 20 and 20 are horizontally moved, respectively. However, the two camera devices 20 and 20 may be integrally fixed so that the two camera devices can be made by a single horizontal movement mechanism. 20 and 20 move in the χγ * direction to obtain a simpler structure. In addition, the above-mentioned position detection devices A and B are provided with two displays 43 and 43 respectively corresponding to the two camera devices 20 and 20, so that the displacement of the field of view s and S can be well followed, and It is advisable to ensure that the area of each field of view s is wide. However, the captured images of the two camera devices 20 and 20 may be displayed on a single display. In addition, the position detection devices A and B described above are examples of dividing the images of the two reference parts 31a and 31a into two and imaging the divided two images by the imaging device, but dividing three or more reference parts A plurality of images corresponding to each of the reference parts may be formed, and the divided plurality of images may be imaged by the imaging device. In addition, the position detection devices A and B may have a configuration in which the optical guidance device 10, the imaging devices 20, 20, the image processing device 42, the displays 43, 43 and the like are included in the same device, or the above-mentioned configuration may be used. A configuration in which a part or each device is provided as an independent device. In addition, the above-mentioned optical guide device 10 is an example having the first reflection device 12, the optical branching device 13, and two second reflection devices 14, 14. However, it is necessary that the images of at least two reference parts can be individually determined. The configuration in which the reference portion is divided into a plurality of corresponding images may be, for example, a configuration including only the optical branching device 13 or a configuration in which an optical branching device and a reflecting device are added to the configuration of the optical guide device 10 described above. In addition, the reference portion of the imaging target of the position detection device A * B is not limited to the reference portion 31a on the mold 30 and 16 on the printing substrate w or the reference portion wla on the printing substrate, and may be, for example, Two fewer alignment marks are set on the mold. Since the invention has the above-mentioned configuration, the following effects can be exhibited. The image of the library scale is divided into pairs according to the respective reference greens. The fine image is used to record the images, so it can be avoided. 2: Solid: The image f interferes with each other. Micro room:-Take a picture of a reference site and detect the seat of each reference site ^ (Patent application scopes 1-3). Furthermore, if the optical guide device and the imaging device are relatively moved, the visual field range of each of the quasi-parts can be easily shifted so that each reference part is included in the visual field range. For example, 'If the reference position is two, the two imaging devices are moved simultaneously: a field port moving in a direction substantially orthogonal to the arrangement direction of the two second reflecting devices'. The movement of the two imaging devices enables two fields of vision. Displace toward approaching and leaving. In addition, when the two reference positions are two, when the two imaging devices are moved simultaneously in a direction substantially parallel to the arrangement direction of the two second reflecting devices, as the two imaging devices are moved, two One of the fields of view is displaced in a direction substantially orthogonal to the moving direction of the imaging device, and the other is displaced in a direction opposite to the moving direction of the one of the fields of view (Patent Application Nos. 4-7). . In addition, according to the positioning method of the printed circuit board described above, the printed circuit board formed on the printed substrate can be easily and accurately superposed on a regular position on a base such as a mold. As a result, the printed circuit board can be punched with high accuracy.
