Description

  The present invention relates to a substrate support device assembling method and a substrate support device assembly support device, and more particularly to improvement of ease of assembly, accuracy, or reliability.

  Various operations such as mounting of electronic circuit components, which are components of the electronic circuit, and application of a highly viscous fluid such as an adhesive are performed on the printed circuit board. When these operations are performed, in order to prevent the printed circuit board from being bent to the back surface side, the printed circuit board is supported on the support member from the back surface side. At that time, as long as the wiring pattern is formed on the back side of the printed circuit board or the electronic circuit component is already mounted on the wiring pattern, the wiring pattern on the back side of the printed circuit board is not formed. In some cases, it is desirable to support only in a certain part, or it is possible to support only in a limited part where no electronic circuit component is mounted. In such a case, the support member is arranged on the support base of the substrate support device so as to support the printed circuit board while avoiding a portion where the printed circuit board cannot be supported or desirably not supported.

For this purpose, Patent Document 1 below proposes that a support member placement work support device supports the placement of a support member on a support base by an operator. This support apparatus is designed to project an image corresponding to a state in which an electronic circuit component is mounted on the back surface of a printed circuit board as seen through from the front surface side of the printed circuit board on a support member support surface of a support base. From the projected image, it can be seen on which side of the printed circuit board the electronic circuit component is mounted, and the operator can place the support member at a position that does not interfere with the electronic circuit component on the support member support surface. .

However, the substrate support surface for supporting the printed circuit board at the tip of the support member is provided so as to be smaller than the bottom surface placed on the support member support surface of the support member and located inside the bottom surface in plan view. In the support by the support member placement work support device described in Patent Document 1, the support member is accurately placed at a position where the board support surface supports the printed circuit board while avoiding interference with the electronic circuit components. May be difficult or impossible. For example, when supporting a place where the mounting density of the electronic circuit components on the back surface of the printed circuit board is high by the support member, the supportable area is narrow, and the support member is placed in a part corresponding to the supportable area of the support member support surface. In some cases, the bottom surface of the support member protrudes from the supportable region, and the image of the electronic circuit component is hidden and cannot be seen, so it is not possible to know whether the substrate support surface is reliably disposed in the supportable region. . Since the bottom surface of the support member does not support the printed circuit board, there is no problem even if it is larger than the image of the supported area, whereas the substrate support surface is smaller than the supported area and is located within the supported area. Therefore, it is necessary to support the supported surface while avoiding interference with the electronic circuit component.
The present invention has been made in the background of the above circumstances, and a substrate support device assembling method and a substrate support device capable of easily, accurately or highly reliably arranging a support member on a support base. It is an object to provide an assembly support device.

The component arrangement display body only needs to represent the arrangement of at least the electronic circuit components on the supported surface of the printed circuit board, and the printed circuit board itself in which the electronic circuit components are already mounted on the supported surface is representative. In addition, for example, an image representing a supported surface of a printed circuit board can be used. This image is a hard copy representing the supported surface, for example, a blueprint of a circuit including an electronic circuit component mounted on a printed circuit board and a conductive wire connecting the electronic circuit components, or a print in which the electronic circuit component is actually mounted It can be obtained by printing image data obtained by imaging the supported surface of the substrate with an imaging device, or can be obtained by displaying the circuit diagram or the image data on a display screen such as liquid crystal.
The support member may be detachably fixed to the support base, or may be fixed detachably. In the former case, for example, the support member includes a magnet and is fixed to the support base by magnetic force, or is fixed to the support base by screws, or is attracted to the support base by negative pressure and fixed. It is supposed to be done. In addition, the support member may support the printed circuit board by the substrate support surface at the tip thereof, and may include an adsorption part such as an adsorption cup, and may adsorb and hold the printed board by negative pressure, or may not include the adsorption part. The printed circuit board may be supported only by the board support surface.

A half mirror is arranged on the first mirror, and a first optical path that is an optical path of light passing through one point on the half mirror and a second optical path that is an optical path of light reflected at the one point on the half mirror. In addition, one of the two optical paths forming a common optical path part that extends in parallel and overlaps with each other in part passes through a supported point that is the center of the portion to be supported by the backup pin on the arrangement display surface. In addition, the problem is solved by adopting a method of arranging and fixing the backup pin on the backup pin support surface in a state where the center of the substrate support surface of the backup pin is positioned on the other of the two optical paths.

The above-described problem further supports the assembly work of the substrate support device in which the support member is arranged and fixed on the support base, and the substrate support surface at the tip of the support member supports one of the supported surfaces of the printed circuit board. An apparatus, (i) a half mirror, (ii) the half mirror, a component arrangement display body representing an arrangement of at least an electronic circuit component on a supported surface of the printed circuit board, and a holding device that holds the support base The holding device includes (a) an arrangement display surface of the component arrangement display body, and (b) if the support member is arranged and fixed on the support base, the substrate support surface of the support member is The support plane, which is the upper plane, forms an angle of 0 ° to 180 ° with each other, and a half mirror is positioned between the arrangement display surface and the support plane, and one point on the half mirror is transmitted. Light of light A first optical path that is a path and a second optical path that is an optical path of light reflected at the one point on the half mirror, and a common optical path portion that is a portion that extends in parallel and overlaps with each other is formed When one of the two optical paths passes through a supported point that is the center of the location to be supported by the support member of the arrangement display surface, the substrate support surface of the support member is placed on the other of the two optical paths. The half mirror, the component arrangement display body, and the support base are held at a relative position where the center of the substrate is positioned, and the board support device assembly support device is connected to the image of the supported point. This can be solved by including a recognition direction limiting device that limits the direction in which the image of the substrate support surface of the support member to support the supported point can be recognized to a certain direction.
The above-mentioned problem is further arranged and fixed in a state where the backup pin is erected at a right angle on the backup pin support surface of the support base, and is supported by one of the both sides of the printed circuit board by the substrate support surface at the tip of the backup pin. An apparatus that supports the assembly work of the board support apparatus that supports the surface is (i) a half mirror, (ii) the half mirror, and a component arrangement display that represents the arrangement of at least the electronic circuit components on the supported surface of the printed circuit board. And a holding device for holding the support base, and the holding device includes (a) an arrangement display surface of the component arrangement display body, and (b) the backup pin is arranged and fixed on the support base. If this is the case, the substrate support surface of the backup pin is a plane located thereon, and the support plane that is spaced upward from the backup pin support surface intersects with each other, and these arrangements The angle between the display surface and the support plane is equally divided into two, and the half mirror is positioned on a plane including the intersection line between the arranged display surface and the support plane, and the optical path of light passing through one point on the half mirror And a second optical path that is an optical path of light reflected at the one point on the half mirror, and a common optical path portion that is a portion that extends in parallel and overlaps with each other is formed 2 When one of the two optical paths passes through a supported point that is the center of the location to be supported by the backup pin of the arrangement display surface, the substrate support surface of the backup pin is placed on the other of the two optical paths. This is solved by holding the half mirror, the component arrangement display body, and the support base at a relative position where the center is located.

The half mirror reflects light incident on the surface of the half mirror in the direction of the reflection angle that is the same angle as the incident angle, while another part is transmitted straight (thickness of the half mirror is negligible) Is allowed). In the substrate support apparatus assembly method and the substrate support apparatus assembly support apparatus, the first optical path and the second optical path include a common optical path portion that extends in parallel with each other and overlaps each other. The first optical path is an optical path of light that passes through the half mirror, and is an optical path that passes through one of the supported point and the substrate support surface of the support member positioned on the support plane, and the second optical path is a half path. An optical path of light reflected by the mirror, which passes through the other of the supported point and the substrate support surface.
Then, one of the first and second optical paths forming the common optical path section passes through a supported point that is the center of the location to be supported by the support member on the arrangement display surface, and on the other of the two optical paths. The substrate support device assembly method and the substrate support device assembly support device for arranging and fixing the support member on the support base in a state where the center of the substrate support surface of the support member is positioned, the light reflected by the half mirror and the half mirror In contrast to the first mode in which the light transmitted through the common light path is incident on the common optical path part, a part of the linear light projected from the common optical path part is reflected by the half mirror, whereas And a second mode in which the part is transmitted through the half mirror. In the first aspect, one image of the periphery of the supported point formed by the light reflected by the half mirror and the substrate support surface is also the periphery of the supported point formed by the light transmitted through the half mirror and the substrate support. Neither the other image of the surface nor the enlargement or reduction is performed (when the first optical path and the second optical path pass through the supported point or the substrate support surface in the normal direction), or both are reduced at the same rate (first optical path). And the second optical path pass through the supported point and the substrate support surface in a direction inclined at the same angle), the image of the periphery of the supported point and the substrate support surface is viewed from the same direction. Therefore, the recognition member placed on the common optical path portion of the first optical path and the second optical path, or the human eye, arranges and fixes the support member at a position where the substrate support surface is recognized by overlapping the supported point. In this case, a target substrate support device can be obtained. In the second aspect, if a projector that projects linear light along the common optical path is disposed on the common optical path, the linear light is divided into two by a half mirror, one of which is supported. The light enters the point, and the other enters the substrate support surface. Therefore, if the projector is positioned at a position where a part of the light projected from the projector enters the supported point, the other part of the light projected from the projector enters the substrate support surface of the support member. It is only necessary to arrange and fix the support member at the position where light is emitted. Actually, the support member placed on the support member support surface of the support base is moved along the support member support surface, and the support member is supported at a position where the light from the projector hits the center of the substrate support surface. It is fixed to the base.
According to the substrate support device assembly method and the substrate support device assembly support device including the projector, the support member can be accurately arranged at an appropriate position on the support base based on an instruction from the projector.
The above-mentioned substrate support device assembly method and substrate support device assembly support device in which the angle formed by the arrangement display surface and the support plane is equally divided and the half mirror is arranged on a plane including the intersection line of the arrangement display surface and the support plane Accordingly, the backup pin can be disposed and fixed at a position where the substrate support surface appropriately supports the supported point of the printed circuit board.
According to the substrate support apparatus assembly support apparatus including the recognition direction limiting apparatus, for example, the half mirror bisects the angle formed by the arrangement display surface and the support plane, and includes an intersection line between the arrangement display surface and the support plane. It is not essential to be placed on a plane.

In other words, the claimable invention should be construed in consideration of the description accompanying each section, the description of the embodiments, the prior art, and the like. The added aspect and the aspect in which the constituent elements are deleted from the aspect of each item can be an aspect of the claimable invention.

(1) A method of assembling a substrate support device in which a support member is arranged and fixed on a support base, and supports a supported surface that is one of both surfaces of a printed circuit board by a substrate support surface at the tip of the support member,
The component arrangement display body having an arrangement display surface representing the arrangement of at least electronic circuit components on the supported surface of the printed circuit board, the support table, and the support member is arranged and fixed on the arrangement display surface and the support table. Then, the substrate support surface of the support member is disposed in a posture that forms an angle of 0 degrees or more and 180 degrees or less with respect to the support plane that is a plane on which the substrate support surface is located, and between the arrangement display surface and the support plane. A first optical path that is an optical path of light passing through one point on the half mirror and a second optical path that is an optical path of light reflected at the one point on the half mirror. One of the two optical paths forming a common optical path portion that extends in parallel and overlaps with each other in part passes through a supported point that is the center of the portion to be supported by the support member on the arrangement display surface. While, the in the state where the center of the substrate supporting surface is positioned in the supporting member, the substrate supporting device assembly method of placing fixing the support member to the support base on the other of the two optical paths.
When performing the method of this section, the relative position between the component arrangement display body and the support base is positioned at a relative position corresponding to the relative position between the printed circuit board and the substrate support device when the substrate support device is actually used. It is desirable that Further, in the case where there is one support member arranged and fixed on the support base, the actual implementation of the method of this section cannot be obtained unless the support member is positioned at the relative position. However, when a plurality of support members are arranged and fixed on the support base to form a substrate support device, the relative positions of the plurality of support members correspond to the relative positions of the plurality of supported points of the printed circuit board. Even if the relative position of the substrate supporting device with respect to the printed circuit board is appropriately adjusted during actual use, there may be a case where there is a profit. Therefore, when the method of this section is performed, the relative position between the component arrangement display body and the support base is set to a relative position corresponding to the relative position between the printed circuit board and the substrate support device when the substrate support device is actually used. Being positioned is desirable but not essential. As the number of support members arranged on the support base increases, the tendency becomes stronger. Normally, when there are three or more support members, the actual benefits can be obtained even if they are not positioned at the relative positions.
(2) The component arrangement display body and the support base are arranged in a state where the arrangement display surface and the support plane intersect each other, and an angle formed by the arrangement display surface and the support plane is divided into two equal parts. In addition, the half mirror is arranged on a plane (referred to as a bisection plane in a narrow sense) including an intersection line between the arrangement display surface and a support plane or a plane parallel to the plane (referred to as a bisection plane in a broad sense) ( A method for assembling a substrate support apparatus according to item 1).
When the half mirror is arranged on a narrowly divided bisection plane, a point where one of the first optical path and the second optical path intersects one of the arrangement display surface and the support plane, and the first optical path, The distance from the intersection of the arrangement display surface and the support plane to the point where the other of the second optical path intersects the other of the arrangement display surface and the support plane is equal to each other. This situation does not change whether the angle formed by the arrangement display surface and the support plane is an acute angle, a right angle, or an obtuse angle. Moreover, it does not change regardless of the angle formed with the half mirrors of the first and second optical paths. Therefore, when one of the first optical path and the second optical path passes through the supported point on the arrangement display surface, the other of the first optical path and the second optical path is placed on the support member support surface of the support base. If the support member is fixed to the support base in a state passing through the center of the substrate support surface of the support member, the support member is arranged and fixed at a position where the substrate support surface appropriately supports the supported point of the printed circuit board. It will be.
However, it is not indispensable that the half mirror is arranged on a narrowly divided bisection plane. For example, considering a state in which a half mirror is arranged on a bisector plane in a narrow sense and a state in which the support plane is translated in a direction perpendicular to the support plane, the half mirror is a plane parallel to the bisector plane in a narrow sense ( This is an example of the case where they are arranged on a broadly divided bisection plane. In this case, the direction of the common optical path portion of the first and second optical paths is not changed, as will be described later in detail in the section of the embodiment. As long as the positions of the plurality of substrate support surfaces on the support plane of the plurality of support members arranged by applying the method of this section are shifted by the same amount in the same direction, the relative positions of the plurality of substrate support surfaces are Since it does not change, an appropriate substrate support apparatus can be obtained.
(3) The arrangement display surface and the support plane are orthogonal to each other, and the half mirror is inclined at an angle of 45 degrees with respect to both the arrangement display surface and the support plane. Substrate support device assembly method.
In this case, when the half mirror is viewed from a direction inclined by 45 degrees with respect to the half mirror, one of the first and second optical paths passes through the supported point in a direction perpendicular to the arrangement display surface. . The coincidence between the supported point and the center of the substrate support surface can be determined in a state where the periphery of the supported point on the arrangement display surface and the substrate support surface of the support member are viewed from a direction perpendicular to them. Even if the direction in which one of the first and second optical paths passes through the supported point is inclined at a small angle from the normal direction of the arrangement display surface, there is almost no difference from the case where it is not inclined (when the inclination angle is 15 degrees or less). Is considered to be included in the method of this section (preferably 8 degrees or less), but if the tilt angle increases, the supported point becomes invisible behind the tall electronic circuit components. Or deformation of the substrate support surface of the support member when viewed from an inclined direction increases, and accordingly, it is difficult to accurately determine the coincidence between the supported point and the substrate support surface. . According to the method of this section, the difficulty can be favorably avoided.
(4) The component arrangement display body and the support base are arranged in a state where the arrangement display surface and the support plane extend in parallel with each other and face each other, and an angle of 45 degrees with the arrangement display surface and the support plane. The half mirror is disposed in an inclined posture that forms the following, and the support member is fixed to the support base in a state where the one of the two optical paths passes through the supported point in a direction perpendicular to the arrangement display surface ( A method for assembling a substrate support apparatus according to item 1).
This term can be considered as a special case where the angle formed by the arrangement display surface and the support plane is zero.
(5) One of the light reflected from the supported point of the component arrangement display body and the light reflected from the substrate support surface of the support member on the support plane is transmitted through a half mirror, and the other is The support member is reflected by a half mirror and reaches the common optical path portion, and the image of the supported point recognized at the recognition point on the common optical path portion matches the image of the substrate support surface. The substrate support apparatus assembling method according to any one of items (1) to (4), wherein the substrate is fixed to the support base.
Each light of the first optical path and the second optical path including the common optical path in the assembling method described in the item (1) enters the half mirror from the supported point and the substrate support surface, and is emitted from the half mirror by reflection and transmission. A mode described in this section is a mode in which the light has a common light path portion after emission. The support member is placed and fixed at a position where the image of the substrate support surface at the tip of the support member and the image of the supported point are seen to overlap each other at the recognition point on the common optical path portion. It can arrange | position correctly at an appropriate support member arrangement | positioning point (The center point of the part where the support member should be arrange | positioned of the support member support surface of a support stand).
The image that can be seen through the half mirror and the image that appears on the half mirror have a wide area, and there are an infinite number of points where they overlap each other, but the half mirror is placed on a narrowly divided bisection plane. In such a case, all of these points are suitable for fixing the support member. However, when the half mirror is arranged on a broadly divided bisection plane, the direction of the line of sight is fixed in a certain direction, and the image of the supported point and the image of the substrate supporting surface only overlap. This is a point suitable for the arrangement and fixing of the support member. In other words, when viewed in a direction parallel to each other from a plurality of recognition points, a plurality of positions where the supported point and the substrate support surface just overlap are suitable positions for fixing and fixing the support member.
Recognition at the recognition point may be performed by a human eye or by a recognition device such as an imaging device. In addition, “the state in which the image of the supported point and the image of the substrate support surface match” means that the two are concentrically overlapped and recognized as well as being recognized separately but at the same position. This includes a state in which this can be recognized. When recognition is performed by the human eye, it is often convenient that both images can be viewed at the same time because it is determined by the human brain whether the positions of the images match. . But not essential. For example, if the relative position of both images can be indirectly recognized by the relative position with the shape representing the center of the field of view or the outer edge of the field of view, such as a crosshair or circle, the images of both are recognized at different times. There is no problem. When it is performed by a recognition device, it is often desirable that both images are recognized at different times in terms of image processing. But not essential. An example of this is when a person sees the image recognized by the recognition device displayed on the display device and judges the coincidence.
In addition, since the supported point itself does not have an area and is not visible, strictly speaking, it should be referred to as “an image of a certain area centered on the supported point” instead of “an image of the supported point”. For simplicity of explanation, the expression “image of supported point” is used.
(6) A projector that projects linear light along the common optical path is disposed on the common optical path, and the linear light projected from the projector passes through the half mirror and displays the component arrangement display. Incident on one of the supported point of the body and the substrate support surface on the support plane and reflected by the half mirror to support the substrate on the component placement display body and the substrate on the support plane The substrate support apparatus assembling method according to any one of (1) to (4), wherein the support member is fixed to the support base in a state of being incident on the other side of the surface.
Each light of the first optical path and the second optical path including the common optical path portion in the assembling method described in the item (1) is reflected by the half mirror, or is transmitted through the half mirror and enters the supported point and the substrate support surface. The mode described in this section is a mode in which the light is directed and has a common optical path portion before entering the half mirror. When linear light is projected onto the common optical path by the projector, the light is divided into two parts by reflection and transmission by the half mirror, and is incident on the corresponding supported point and the substrate support surface, The support member placement point is indicated by light. Therefore, if the support member is fixed to the support base in a state where linear light is incident on the center of the substrate support surface at the tip, the support member is accurately positioned at the support member arrangement point corresponding to the supported point. Can be arranged.
In addition, it is desirable that the projection direction of the linear light of the projector is constant, but when the half mirror is arranged on a narrowly divided bisection plane, the projector projects light in an arbitrary direction. It can be. For example, the position of the projector may be constant, and the projection direction may be arbitrarily changed.
(11) A device that supports the assembly work of a substrate support device in which a support member is arranged and fixed on a support base, and the substrate support surface at the tip of the support member supports one of the supported surfaces of the printed circuit board. And

When passing through a supported point, which is the center of the portion to be supported by the support member, the relative position where the center of the substrate support surface of the support member is located on the other of the two optical paths, Her Mirror, the substrate supporting device assembly support device is to hold the support table the component arrangement display body and.

As shown in FIG. It is supposed to be fixed as possible. The board pressing member 110 includes a columnar mounting portion 112 and a plate-shaped pressing portion 114 extending perpendicularly from one axial end portion of the mounting portion 112, and a magnet 116 (see FIG. 3). ) Is buried. The substrate mounting surface 90 is also provided with at least one, for example, two filter mounting portions 120 at an end portion extending from the rotation axis of the second holding member 68.

  The blocking filter 64 constitutes a visual recognition direction limiting device that is a recognition direction limiting device, and is configured, for example, in the same manner as the louver film described in JP-A-2004-109615, and has two louver layers as conceptually shown in FIG. 130 and 132 are provided. Each of these louver layers 130 and 132 is a film having a large number of fine louvers 134 formed therein, and the louvers 134 are formed in parallel at equal intervals and perpendicular to the surface of the film.

The assembly of the substrate support apparatus 10 will be described.
The printed circuit board 86 is supported by the substrate support surface 44 of the backup pin 16 on one side of the printed circuit board 86, and the surface opposite to the work surface on which the work is performed. The backup pin 16 is attached to a position suitable for supporting the printed circuit board 86 on the support surface 14 of the support base 12. For example, when the work to be performed on the printed circuit board 86 is mounting of electronic circuit components, and electronic circuit components are mounted on both surfaces thereof, the electronic circuit components are mounted on the other surface after mounting the electronic circuit components on one surface. When the circuit board is mounted, the board supporting device 10 supports the surface of the printed circuit board 86 on which the electronic circuit components are already mounted as a supported surface, and the backup pin 16 interferes with the electronic circuit parts of the supporting surface 14. Therefore, it is necessary to arrange the printed circuit board 86 at a position where the printed circuit board 86 can be supported. The backup pin 16 also supports the portion of the supported surface where the wiring pattern is provided. However, in some cases, the backup pin 16 is disposed so as to avoid interference with the wiring pattern.

  The arrangement of the backup pin 16 is supported by the support device 8. For the support, for example, the printed circuit board 86 is actually a product on which the electronic circuit component 150 is actually mounted, and the electronic circuit component 150 is mounted on the surface on which the electronic circuit component 150 is first mounted. The printed circuit board 86 is used as a component arrangement display body. Therefore, as shown in FIGS. 1 and 2, the printed circuit board 86, the support base 12, the half mirror 60, and the cutoff filter 64 are set in the holding device 62. In the holding device 62, the second holding member 68 is positioned at the use position, and the board mounting surface 90 is set to be perpendicular to the support base holding portion 70 of the first holding member 66. Then, the support base forming plate 18 is placed on the support base holding part 70, and the positioning holes 24 are fitted to the positioning pins 74. Depending on the size of the printed circuit board 86, if necessary, the support base forming plate 20 is fitted to the support base forming plate 18, and the support base forming plate 22 is further fitted to the support base forming plate 20. Further, as shown in FIG. 1, the printed circuit board 86 has a component mounting surface on which the electronic circuit component 150 is not yet mounted on the substrate mounting surface 88 of the second holding member 68 as the substrate mounting surface 90 side. The surface on which the circuit component 150 is mounted, and the supported surface 152 supported by the backup pin 16 is placed on the front side so as to function as an arrangement display surface, and straight on the board mounting surface 90 In addition, it is sandwiched from both sides by a pair of positioning members 96 and positioned with respect to the support base 12. Further, the edge portion of the printed circuit board 86 is pressed by the pressing portion 114 of the substrate pressing member 110 and is sandwiched and fixed between the substrate mounting surface 90. As a result, as shown in FIG. 2, the supported surface 152 of the printed circuit board 86 and the support surface 14 of the support base 12 are perpendicular to each other, and the backup surface 152 and the backup surface erected at a right angle on the support surface 14. The support plane 154 that is the plane on which the substrate support surface 44 of the pin 16 is positioned is orthogonal to each other. The substrate mounting surface 88 and the pair of positioning members 96 constitute a substrate positioning portion, and constitute a relative position positioning portion together with the support base positioning portion.

After the printed board 86 is set, as shown in FIG. 2, the free end of the half mirror 60 (the end on the side where the blocking filter 64 is not attached) is a pair of mirror attaching portions 76 of the first holding member 66. The free end portion (the end portion on the side where the half mirror 60 is not connected) of the cutoff filter 64 is fitted into each groove 78 of the pair of filter mounting portions 120 of the second holding member 68. The half mirror 60 and the cutoff filter 64 are held by the holding device 62. The holding device 62 also serves as a cutoff filter holding device. The groove 78 of the mirror mounting portion 76 is provided with an inclination of 45 degrees with respect to the support base holding portion 70, the substrate mounting surface 90 is perpendicular to the support base holding portion 70, and the half mirror 60 has the substrate mounting surface 90. The supported surface 152 and the support plane 154 between the supported surface 152 of the printed circuit board 86 attached to the support board 15 and the support plane 154 by the backup pin 16 attached to the support board 12 held by the support board holding unit 70. It is in a state of being inclined at an angle of 45 degrees with respect to the angle. The half mirror 60 is also disposed on a bisected plane in a narrow sense defined by the supported surface 152 and the support plane 154. The position of the support plane 154 in the direction perpendicular to the support base holding part 70 is determined by the thickness of the support base 12 and the height of the backup pin 16, and the position of the support plane 154 and the printed circuit board 86 supported surface 152. , And the half mirror 60 bisects the right angle that is the angle between the supported surface 152 and the support plane 154, and between the supported surface 152 and the support plane 154. It is arranged on a bisected plane in a narrow sense, which is a plane including intersecting lines. Further, the groove 122 of the filter mounting portion 120 is provided at a right angle to the substrate mounting surface 90, and the cutoff filter 64 is inclined at an angle of 45 degrees with respect to the half mirror 60, and the supported surface 152 of the printed circuit board 86. Is perpendicular to the support surface 14 of the support 12 and is positioned on the same side as the printed circuit board 86 with respect to the half mirror 60.
In this embodiment, the groove 122 of the filter mounting portion 120 is deep enough to maintain the cutoff filter 64 in a horizontal posture, and the groove 78 of the mirror mounting portion 76 is shallow, so that the half mirror 60 is free. The end is positioned and supported. However, it is possible to make the groove 122 shallower and the groove 78 deeper. In any case, one of the two grooves 78 and 122 is deep and securely holds one of the half mirror 60 and the blocking filter 64 and determines the extending direction of one of the two grooves 78 and 122. It is desirable to fulfill the function of determining the position of the other free end of the cutoff filter 64. It is also possible to provide a fixing member such as a set screw that prevents the half mirror 60 or the cutoff filter 64 from coming out of the groove at the attachment portion on the deep groove side.

  Further, the relative position between the printed circuit board 86 and the support base 12 in the holding device 62 is such that the printed circuit board 86 is actually used in an electronic circuit component mounting system in which the substrate support apparatus 10 is a kind of a substrate work system. It is positioned at a relative position corresponding to the relative position with respect to the substrate support apparatus 10. As described above, the support 12 is positioned in the direction in which the pair of positioning pins 74 are aligned and in a direction perpendicular to the alignment direction in one plane parallel to the support surface 14 by being fitted to the positioning pins 74. The printed circuit board 86 is placed on the board placement surface 88 and sandwiched between the pair of positioning members 96, so that a direction perpendicular to the board placement surface 88 in a plane parallel to the supported surface 152 is obtained. The pair of positioning members 96 are positioned in the moving direction. The substrate placement surface 88 is also a substrate positioning surface of the substrate positioning member. As described above, in the present embodiment, the support base 12 is positioned with the positioning hole 24 as a positioning reference, and the printed circuit board 86 has a mounting surface mounted on the substrate mounting surface 88 and a side surface sandwiched between the positioning members 96. Although these are positioned as positioning references, these positioning references are positioning references for positioning the substrate support device 10 and the printed circuit board 86 in the electronic circuit component mounting system. In the electronic circuit component mounting system, the substrate support device 10 and the printed circuit board 86 are respectively positioned by the positioning device and in the transport direction by the substrate transport device and in the direction orthogonal to the transport direction in a plane parallel to the component mounting surface and the supported surface. The supported surface 152 and the support surface 14 extend in parallel with each other and face each other, and the supported point (the center point of the portion to be supported by the backup pin 16 of the supported surface 152) and the supported surface The substrate support surface 44 of the backup pin 16 that supports the support point is opposed to each other. Therefore, in the holding device 62 of the support device 8, the pair of positioning pins 74, the substrate mounting surface 88, and the pair of positioning members 96 are the same as the positioning in the electronic circuit component mounting system for the support base 12 and the printed circuit board 86. The state where the supported point corresponds to the center point of the substrate support surface 44 of the backup pin 16 that supports the supported point, that is, the light passing through the supported point, and the backup pin 16 is the pin arrangement point (support surface 14). In the state where the backup pin 16 is arranged at the center point), the light passing through the center of the substrate support surface 44 of the backup pin 16 is incident on the same point of the half mirror 60, and the former light. The optical path of the reflected light reflected by the half mirror 60 and the optical path of the transmitted light that is the latter light and transmitted through the half mirror 60 extend parallel to each other. And a common optical path portion is formed on top of each other, is provided so as to position the relative positional relationship to reach the same recognition point.

  The operator puts the backup pin 16 on the support base 12 while looking through the blocking filter 64 and viewing the images of the substrate support surface 44 and the supported surface 152. Since the cutoff filter 64 is located on the free end side of the support base holding part 70 and is configured to limit the visible range of the operator looking into the cutoff filter 64 from above in the vertical and horizontal directions of the face. As shown in FIG. 6, the operator only needs a part of the blocking filter 64 where the line of sight is perpendicular to the blocking filter 64 and parallel to the light incident at right angles to the blocking filter 64. Each image of the substrate support surface 44 and the supported point can be seen, and the portion where the line of sight is oblique with respect to the cutoff filter 64 is dark, and the image is not visible. Therefore, the operator is reflected from the supported surface 152 in the normal direction to the supported surface 152, reflected by the half mirror 60 in the direction of 45 degrees with respect to the surface of the half mirror 60, and incident on the blocking filter 64 at a right angle. The periphery of the supported point is observed by looking at the image of the incident light and the image of the light reflected from the substrate support surface 44 in the normal direction with respect to the substrate and passing through the half mirror 60 and entering the blocking filter 64 at a right angle. And the substrate support surface 44 is equivalent to viewing from a direction perpendicular to them. This visual recognition is also visual recognition in a direction parallel to a plane perpendicular to the line of intersection of the supported surface 152 and the support plane 154, or visual recognition in a plane parallel to the inclination direction of the half mirror 60 and perpendicular to the half mirror 60. is there. In addition, the half mirror 60 is inclined at an angle of 45 degrees with respect to the supported surface 152 and the supporting plane 154, and the operator also placed the image of the supported surface 152 on the support table 12. The image of the substrate support surface 44 of the backup pin 16 can also be seen in actual size.

  The operator passes through the supported point and the center point of the substrate support surface 44 of the backup pin 16 arranged at the pin arrangement point corresponding to the supported point, and enters the cutoff filter 64 at a right angle. The images of the supported surface 152 and the substrate support surface 44 are viewed at a recognition point on the common optical path formed by light, and the operator moves his eyes and looks into the blocking filter 64 to image the supported surface 152. If a supported area including a supported point is found, an image of the substrate support surface 44 can be seen in the supported area of the support surface 14, and the image of the supported point and the substrate support surface can be seen. By placing the backup pin 16 at a position where the 44 images just overlap and appear to concentrically overlap, the backup pin 16 can be accurately placed at the pin placement point. The backup pin 16 is fixed to the support base 12 with one of the two lights forming the common optical path section passing through the supported point and the other passing through the center of the substrate support surface 44. The half mirror 60 is arranged on a narrowly divided bisection plane, and the light path reflected by the half mirror 60 of the two lights forming the common optical path section intersects the supported surface 152; The distance from the intersection of the supported surface 152 and the substrate support surface 44 to the point where the optical path of the light passing through the half mirror 60 intersects the substrate support surface 44 is equal to each other, and the image of the substrate support surface 44 is supported. If the backup pin 16 is arranged at a position where the dot image appears to overlap, the substrate support surface 44 is positioned at a position where the distance from the intersection line is equal to the distance from the intersection line of the supported point. 16 is arranged at a position that appropriately supports the supported point. The same applies to any of the plurality of backup pins 16 arranged and fixed on the support base 12, and these backup pins 16 are arranged on the support surface 14 in a state having the same relative positional relationship as the relative positions of the plurality of supported points. As a result, the substrate supporting apparatus 10 that appropriately supports the printed circuit board 86 is obtained. Since the see-through window of the blocking filter 64 is sized so that a relatively large supported area can be visually recognized, it is concentric with the supported point in a state where the supported point is located in the center of the see-through window as much as possible. It is desirable to place the backup pin 16 at a proper position.

The backup pin 16 has a rod shape, the substrate support surface 44 is the tip surface of the tapered support portion 42, and is smaller than the mounting portion 40 having a larger diameter than the substrate support surface 44. Although the mounting portion 40 appears to overlap, the mounting portion 40 is below the substrate support surface 44 and far from the half mirror 60, so that the operator's point of view matches the substrate support surface 44 and can be supported. It can be determined whether or not it is located within the region. If the optical characteristics of the substrate support surface 44 and the tapered surface of the support portion 42 are made different from each other, for example, the reflectance can be made different from each other such that one is 70% or more and the other is 30% or less. In this case, the substrate support surface 44 can be more easily recognized.
Further, in the present embodiment, the reflectance of the incident light of the half mirror 60 is 70% and the transmittance is 30%, but the cutoff filter 64 is provided so as to be positioned on the printed circuit board 86 side with respect to the half mirror 60. Since the reflected light from the supported surface 152 of the printed circuit board 86 is reflected by the half mirror 60 and is incident on the cutoff filter 64, the amount of image formation on the supported surface 152 is large, and the state of the supported surface 152 is clear. Even when small electronic circuit components 150 are mounted on the supported surface 152 with high density, the supported region can be accurately identified, and the pin arrangement of the backup pin 16 without causing interference with the electronic circuit component 150 can be achieved. Can be placed at a point. The supported surface 152 is provided with a wiring pattern. In principle, the backup pin 16 is disposed so as to avoid interference with the wiring pattern. However, the wiring pattern is thin, and even if supported by the backup pin 16, there is almost no trouble. Instead, if necessary, the wiring pattern portion can be supported by the backup pin 16.

  When the support device 8 is not in use, as shown by a two-dot chain line in FIG. 3, the half mirror 60 and the cutoff filter 64 are combined and placed on the support holding portion 70 of the first holding member 66, so that the second holding The member 68 is rotated, folded to the support base holding part 70 side, the free end part is placed on the cutoff filter 64, and is put away in a grouped state.

  As in the support device 200 shown in FIG. 7, the reflected light from the supported surface 152 of the printed circuit board 86 passes through the half mirror 204 and enters the blocking filter 202 at a right angle. The reflected light from the support surface 44 may be reflected by the half mirror 204 in the direction of 45 degrees and incident on the blocking filter 202 at a right angle. The rest of the configuration of the support device 200 is the same as that of the support device 8, and the same reference numerals are given to the constituent elements that perform the same actions, and the description thereof is omitted.

  The blocking filter 202 and the half mirror 204 are rotatably connected by a shaft 206, and a pair of filter mounting portions 210 each having a groove 208 are shown in the support base holding portion 70 (only one is shown in FIG. 7). The free end of the cutoff filter 202 is fitted and held. The depth of the groove 208 is provided at a right angle to the support base holding part 70, and the cutoff filter 202 is held at a right angle to the support base holding part 70, and the support base held by the support base holding part 70. The support surface 14 of 12 and the substrate support surface 44 of the backup pin 16 are perpendicular to the support plane 154 where the support surface 14 is located, and parallel to the supported surface 152 of the substrate 86 held by the second holding member 68.

  The transmittance of incident light of the half mirror 204 is, for example, 40%, the reflectance is 60%, and the amount of image forming light on the supported surface 152 is increased so that it can be seen as clearly as possible. For example, if the electronic circuit component mounted on the supported surface 152 is small and the image is difficult to see, for example, the operator looks into the blocking filter 202 with the magnifying lens 212 and displays an image of the small electronic circuit component. Zoom in and look for supported points accurately. Also in the support device 200 of the present embodiment, as in the support device 8, the operator looks through the blocking filter 202 and sees the image reflected on the half mirror 204, while supporting the supported surface 152 of the support surface 14. The backup pin 16 is placed at a position where the image of the substrate support surface 44 can be seen in the image of the possible area, and the image of the supported point and the image of the substrate support surface 44 appear concentrically.

You may make it show the position which arrange | positions the support member of the support surface of a support stand by the projection of the light by a projector. The embodiment will be described with reference to FIGS.

Is provided. The depth direction of the groove 266 is provided to be inclined by 45 degrees with respect to each of the holding portions 260 and 262. Also in the present embodiment, the holding portions 260 and 262 and the mirror mounting portion 268 are provided so that the half mirror 252 is disposed on a narrowly divided bisection plane between the supported surface 152 and the support plane 154.

  As shown in FIG. 8, the laser pointer moving device 258 moves the laser pointer 256 manually by an operator, and is within one plane parallel to the supported surface 152 of the printed circuit board 86 held by the board / mirror holding unit 262. It is comprised so that it may move to arbitrary positions. Therefore, a slide 286 as a movable member is provided on a frame 284 provided at a position away from the substrate / mirror holding part 262 of the support base holding part 260 so as to be movable in a direction parallel to the holding parts 260 and 262. A guide rail 288 as a pair of guide members is provided on the slide 286, and the slide 290 as another movable member is moved in a direction perpendicular to the support base holding portion 260 by the guide rails 288. The laser pointer 256 is mounted on the slide 290 in a posture perpendicular to the substrate / mirror holding unit 262. By the movement of the slides 286 and 290, the laser pointer 256 is moved to an arbitrary position in a plane parallel to the supported surface 152. And a laser beam as linear light is projected onto an arbitrary position of the supported surface 152. The frame 284 also functions as a guide member for guiding the movement of the slide 286, and constitutes a guide device together with a pair of guide rails 288, and guides the movement of the laser pointer 256 while maintaining a posture perpendicular to the substrate / mirror holding portion 262. To do.

  At the time of assembling the substrate support apparatus 10, as shown in FIG. 9, the support base 12 is positioned by the positioning pins 264 and held by the support base holding part 260. The printed circuit board 86 is placed on the board placement surface 270, is attached to the board mounting surface 272, is sandwiched and positioned by a pair of positioning members 276, and is pressed by the board pressing member 278. The supported surface 152 is held at right angles to the support surface 14 and the support plane 154. The printed circuit board 86 and the support base 12 are positioned in the same manner as in the above embodiment by using a positioning reference for positioning in the electronic circuit component mounting system. Further, the half mirror 252 is fitted in the groove 266 of the mirror mounting portion 268 and is held in an inclined state at an angle of 45 degrees with respect to both the supported surface 152 and the support plane 154.

  Therefore, the laser pointer 256 projects a laser beam from a direction inclined by 45 degrees with respect to the half mirror 252, and part of the light projected from the laser pointer 256 passes through the half mirror 252 and is supported on the supported surface 152. , And another part is reflected by the half mirror 252 and enters the support surface 14 at a right angle, and enters the substrate support surface 44 of the backup pin 16 erected on the support surface 14 at a right angle. In this embodiment, a laser pointer 256 is provided in a common optical path portion where two optical paths that intersect the supported surface 152 and the support plane 154 at right angles and extend in a direction inclined by 45 degrees with respect to the half mirror are overlapped. A laser beam is projected along the optical path.

  An operator looks at the supported surface 152 through the half mirror 252 to find a supported point, moves the laser pointer 256 to a position facing the supported point, and projects a laser beam toward the supported surface 152. The projected laser beam passes through the half mirror 252 and is incident on the supported point in a direction normal to the supported surface 152, and is reflected by the half mirror 252 in a direction of 45 degrees with respect to the half mirror 252. If the operator places the backup pin 16 on the support surface 14 in a state where the laser beam is incident on the center of the substrate support surface 44, the support surface 14 corresponds to the supported point. Therefore, the backup pin 16 can be accurately placed at the pin placement point.

When the backup pin 16 is placed so that the substrate support surface 44 is positioned at a position designated by light, the substrate support surface 44 becomes the supported surface 152. The backup pin 16 is disposed in a state where the distance from the intersection line between the support plane 154 and the support plane 154 is located at a position equal to the distance from the intersection line of the supported point. The operator moves the laser pointer 256 to sequentially project the laser beam onto the supported point, and places the backup pin 16 at the pin placement point designated by the laser beam.

The printed circuit board 86 and the support base 12 are held at a right angle by a holding device 334, and stand at the pin arrangement point corresponding to the light reflected from the supported point in the direction of the normal to the supported surface 152. The half mirror 332 provided at 45 degrees with respect to the supported surface 152 and the support plane 154 is inclined from the light reflected in the direction normal to the support plane 154 from the substrate support surface 44 of the backup pin 16 provided. After being emitted from the half mirror 332, they overlap to form a common optical path portion parallel to the center line of the incident light restricting cylinder 338 and reach the same recognition point.

  When the operator places the backup pin 16 on the support base 12, as shown in FIG. 12, the operator sees the support surface 14 and the supported surface 152 through the incident light limiting cylinder 338, and enters the recognition point from them. The angle of light is limited by the incident light limiting cylinder 338, and the worker's visual recognition range is a range in which the reflected light enters the incident light limiting cylinder 338 and reaches the magnifying lens 356 among the support surface 14 and the supported surface 152. Limited to The inner diameter of the incident light restricting cylinder 338 is such that the worker's visual recognition range can visually recognize from the image of the supported surface 152 that an empty portion where no electronic circuit component is mounted is a supported region. It is as small as possible, and the image of the supported area by the reflected light in the normal direction from the supported surface 152 and a slight image of the periphery thereof, and the reflected light in the normal direction from the substrate supporting surface 44 The angle of the incident light to the recognition point restricted by the incident light restricting cylinder 338 is such a size that the worker's visible range is restricted as described above.

At this time, for example, the illumination devices 440 and 442 are both in the light irradiation state, and the operator looks at the substrate support surface 44 and the supported surface 152 at the same time, but the incident light restriction cylinder 430 restricts the incident light. Similar to the cylinder 338, the direction of light visible to the operator is limited, and the viewing range of the support surface 14 and the supported surface 152 is limited. Only light reflected in the line direction and light reflected in the normal direction from the substrate support surface 44 to the support plane 154 will be seen. The light reflected in the normal direction from the supported point is reflected in the horizontal direction by the total reflection mirror 424, enters the half mirror 402, passes through the half mirror 402, and is transmitted from the backup pin 16 arranged at the pin arrangement point. The light reflected in the normal direction from the center of the substrate support surface 44 is reflected in the horizontal direction by the total reflection mirror 422 and reflected upward by the total reflection mirror 426, and from the above supported point of the half mirror 402. Is incident on the same point as the incident light, and is reflected by the half mirror 402 in the direction of 45 degrees with respect to the half mirror 402 and overlaps with the light transmitted through the half mirror 402 to form a common optical path portion, and reaches the recognition point. The operator is equivalent to seeing the periphery of the supported point and the substrate support surface 44 from a direction perpendicular to them, and the operator can select the supported point and the corresponding pin. The coincidence of the center of the substrate supporting surface 44 of the backup pins 16 disposed 置点 can be accurately determined.

  Therefore, the operator moves the backup pin 16 placed on the support base 14 along the support surface 14, and the substrate support surface 44 in the image of the supported area of the support surface 152 of the support surface 14. If the backup pin 16 is placed at a position where the image of the substrate support surface 44 appears concentrically with the image of the supported point, the backup pin 16 is accurately placed at the pin placement point corresponding to the supported point. be able to. Since the illumination devices 440 and 442 irradiate the substrate support surface 44 and the supported surface 152 with light from a direction perpendicular to them, the shadow of the backup pin 16 and the electronic circuit component is not formed. Without being obstructed, the supported point can be searched and the backup pin 16 can be accurately placed at the pin placement point. The operator operates the moving device, looks into the half mirror 402, searches for a supported area, and arranges the backup pin 16. In addition, since the images of the supported surface 152 and the substrate support surface 44 are magnified by the magnifying lens 432, interference with the electronic circuit components does not occur even in places where small electronic circuit components are mounted at high density. The backup pin 16 can be accurately arranged at the pin arrangement point. Further, the length of the optical path until the reflected light in the normal direction from the supported surface 152 enters the half mirror 402 and the optical path until the reflected light in the normal direction from the substrate support surface 44 enters the half mirror 402. Therefore, the operator can see both the supported point and the substrate support surface 44 in a focused state.

  The support surface 14 and the supported surface 152 may be selectively illuminated by the illumination devices 440 and 442. For example, first, the illumination device 442 is set in an illumination state, the illumination device 440 is set in a non-illumination state, light is irradiated only on the supported surface 152, the half mirror 402 and the light guide device 406 are moved, and a supported point is searched. If the supported point is found, the illuminating device 442 is set to the non-illuminated state, the illuminating device 440 is set to the illuminating state, and only the support surface 14 is viewed. 16 is put.

  When the holding device holds the printed circuit board and the support base in a relative positional relationship in which the supported surface and the support plane face each other in a parallel posture, the supported surface is supported in a direction parallel to the supported surface and the support plane. It is not essential that the positions of the point and the support member arrangement point coincide with each other and be held in a position facing each other in a direction perpendicular to the supported surface and the support plane. It is good also as an apparatus which hold | maintains in a position where a to-be-supported point and a supporting member arrangement | positioning point have shifted | deviated in the direction parallel to a to-be-supported surface and a support plane. The embodiment will be described with reference to FIG.

  Similar to the holding device 404, the holding device 472 of the support device 470 of the present embodiment includes a support stand holding portion 474 and a substrate holding portion 476 provided in parallel with each other, and positions the support stand 12 with positioning pins 478. The printed circuit board 86 is positioned and held by the board mounting surface 480, the board positioning surface 482, the board positioning member 484, and the board pressing member 486. The positioning pins 478 are provided so as to position the support base 12 with respect to the printed circuit board 86 while shifting the positions in one direction parallel to the support plane 154 and the supported surface 152. However, the positioning is performed by using a positioning reference for positioning in the electronic circuit component mounting system as in the above embodiments.

  The light guide device 500 includes a device main body 502, a half mirror 504, and a total reflection mirror 506. The total reflection mirror 506 faces the supported surface 152 and is inclined by 45 degrees with respect to the supported surface 152, and the half mirror 504 is relative to the surface perpendicular to the supported surface 152 with respect to the total reflection mirror 504. And inclined by 45 degrees with respect to the supported surface 152 and the support plane 154. The light guide device 500, the support base holding unit 474, and the substrate holding unit 476 are configured so that the normal path reflected light from the supported surface 152 enters the half mirror 504 and the length of the optical path from the substrate support surface 44. The length of the optical path until the reflected light in the normal direction enters the half mirror 504 is substantially equal. Further, the apparatus main body 502 is provided with illumination devices 508 and 510 facing the half mirror 504 and the total reflection mirror 506, respectively, and constitutes an incident light limiting cylinder 512 and a lens system of the recognizable light limiting device 511. A magnifying lens 514 is provided.

  Therefore, the light reflected from the supported surface 152 is reflected by the total reflection mirror 506, passes through the half mirror 504, and the light reflected from the substrate support surface 44 is reflected by the half mirror 504. The incident light is limited by the incident light limiting cylinder 512, and the operator is equivalent to viewing the supported surface 152 and the substrate supporting surface 44 from a direction perpendicular to them. Positioning pins 478 for positioning the support base 12 of the holding device 472 are reflected and transmitted by the half mirror 504 (common to the support base 12 with respect to the printed circuit board 86 and the position of the pin placement point with respect to the supported point). And the light reflected from the supported point in the normal direction to the supported surface 152 and reflected by the total reflection mirror 506 in the direction of 45 degrees, and the pin arrangement point. The light reflected from the substrate support surface 44 of the arranged backup pin 16 in the normal direction to the support plane 154 is positioned so as to be incident on the same point of the half mirror 504. The image and the image of the substrate support surface 44 can be seen superimposed.

  Also in the support device 470, the light guide device 500 is moved in a direction parallel to the supported surface 152 and the support surface 14 by a moving device (not shown). The operator looks into the incident light limiting cylinder 512 and moves the light guide device 500 to search for a supported point. The operator can see the images of the substrate support surface 44 and the supported point by looking through the incident light restricting cylinder 512, so that the images can be seen without being displaced, and the image of the supported point is displayed on the substrate support surface. The backup pins 16 are arranged so that the 44 images overlap. The length of the optical path until the reflected light in the normal direction from the supported surface 152 enters the half mirror 504 and the length of the optical path until the reflected light in the normal direction from the substrate support surface 44 enters the half mirror 504 Therefore, both the image of the supported point and the image of the substrate support surface 44 can be seen in a focused state.

  In each of the above embodiments, the supported surface 152 and the substrate support surface 44 are viewed from the normal direction which is the most desirable direction, or the laser beam is incident in the normal direction. It is not essential. For example, when the half mirror is arranged on a bisected plane in a narrow sense of the supported surface and the support plane, an image of the supported point and an image of the substrate support surface of the support member that should support the supported point are obtained. In addition to limiting the recognizable direction to the normal direction, it is not essential to limit the direction to a certain direction. There are innumerable directions of light reflected from the supported point and the center of the substrate support surface of the support member arranged at the support member arrangement point that should support the supported point, and light passing through the supported point and There are innumerable directions of common optical path portions where two lights that pass through the center of the substrate support surface and are reflected by the half mirror and transmitted through the half mirror overlap, but in any of these common optical path portions Even if the image of the support point and the image of the substrate support surface are recognized, if the half mirror is arranged on a narrowly divided bisection plane, the supported point and the substrate support through which the two optical paths forming the common optical path section pass If the support member is disposed at a position where the distance from the intersection line of the supported surface and the support plane with the center of the surface becomes equal to each other and the image of the supported point and the image of the substrate support surface overlap, Can be placed at the support member placement point It is kill the.

  As shown by the solid line in FIG. 15, when the supported surface and the support plane are provided at right angles and the half mirror is arranged on a narrowly divided bisection plane, the supported point indicated by a circle in the figure is an example. If seen from a direction inclined 45 degrees with respect to the half mirror as shown by a thin line, or even if seen from a direction inclined at an angle smaller than 45 degrees with respect to the half mirror as shown by a broken line, The center of the substrate support surface where the image overlaps the image of the supported point is the position indicated by a circle, and it is the same even if the viewing direction is different. It can arrange | position in the position which should be supported. Further, the support member can be arranged at the support member arrangement point corresponding to the supported point by changing the direction of the line of sight while the operator fixes the position of the eyes. A substrate in which an image of a supported point indicated by a circle is seen to overlap the image of the supported point even when the image of the supported point indicated by a triangle is viewed at the position of an eye when the image of the supported point indicated by a circle is viewed in the direction indicated by a broken line The distance from the intersection line between the supported surface and the support plane at the center of the support surface is equal to the distance between the supported point and the intersection line, and the support member can be placed at a position where the supported point should be supported. is there.

  The above describes the case where the direction of the recognition point or line of sight is changed in a plane that is parallel to the inclination direction of the half mirror and orthogonal to the half mirror (a plane orthogonal to the line of intersection between the supported surface and the support plane). The direction of the line of sight may be changed to a direction inclined with respect to the plane perpendicular to the half mirror. For example, as shown in FIG. 16, the center of the substrate support surface is located at the point indicated by a circle on the support plane in a state where the supported point indicated by the circle is viewed from the viewpoint A via the point B on the half mirror. As described above, if the support member is arranged so as to be positioned, the substrate support surface of the support member will support the printed circuit board at the supported point indicated by the circles. Instead of C, the support member may be arranged in a state where the center of the substrate support surface is located at a position that coincides with the supported point indicated by the □ mark recognized through the point B. The viewpoint C is a point obtained by turning the viewpoint A around the turning center line 550 passing through the point B and orthogonal to the half mirror. As shown in FIG. C is located on a common circumference 552. When the point B is viewed from the viewpoint C, it appears that the supported point indicated by the □ mark and the center of the substrate support surface indicated by the □ mark coincide with each other.

It is clear that the point seen through the half mirror is the intersection of the straight line CB and the support plane, but between that point and the point on the supported surface that is reflected by the half mirror and seen at the viewpoint C. For example, the relationship can be understood as follows. In FIG. 17, when the viewpoint A moves to the position of the viewpoint C, the supported point to be supported by the substrate supporting surface that can be seen through the point B is the point C and the point C on the circumference 552 according to the law of reflection. It should be located on a straight line passing through point D and point B which are in a symmetrical relationship. According to the law of reflection, the angle formed by the straight line passing through the viewpoint C and the point B and the straight line passing through the point D and the point B with respect to the turning center line 550 in one plane including the turning center line 550. Because they are the same. Further, assuming a circumference 554 that is symmetrical to the circumference 552 with respect to the half mirror, the light from the substrate support surface at the position indicated by □ is as shown in FIG. In addition, on the circumference 554, it should proceed along a straight line connecting the point E and the point B located at the same position as the point D on the circumference 552. This is to imagine the relative position between the straight line CBE and the circumferences 552 and 554 when viewed in the direction from the circumference 552 to the circumference 554 (directions of arrows J and K) along the turning center line 550. You can understand. Since the relative positional relationship between the circumference 552 and the supported surface and the relative positional relationship between the circumference 554 and the supporting plane are the same, the intersection of the straight line BD and the supported surface, the straight line BE and the supporting plane The point of intersection is in a plane-symmetric relationship with the half mirror. That is, the supported point indicated by □ and the substrate support surface are symmetrical with respect to the half mirror, and the supported point and the center of the substrate support surface coincide with each other (position indicated by □). If the support member is disposed so that the substrate support surface is located, the support member is disposed at a position suitable for supporting the supported point indicated by the □ mark.
As described above, the support member is arranged with the center of the substrate support surface coinciding with the supported point in a state where the direction of the line of sight is inclined with respect to a plane parallel to the inclination direction of the half mirror and perpendicular to the half mirror. Even so, it is clear that the support member has been placed in the proper position.

  On the other hand, as shown by a two-dot chain line in FIG. 15, if the support plane that defines the bisectoral plane in the narrow sense is moved in a direction perpendicular to the support plane, the half mirror becomes the second magnitude in the broad sense. It will be arranged on the division plane. In this case, when the supported point is viewed from the same direction as when the half mirror is arranged on a narrowly divided bisection plane, the image overlaps the image of the supported point as indicated by the Δ mark. The center point of the substrate support surface is deviated from the position when the half mirror is arranged on the narrowly divided bisection plane on the support plane. However, the direction in which the image of the supported point is viewed is constant. For example, if the image of the supported point indicated by □ is viewed from a direction parallel to the direction of viewing the supported point indicated by △, the image The amount and direction of the shift of the center point of the substrate support surface that appears to overlap the image of the support point on the support plane is the same as the center point of the substrate support surface with respect to the supported point indicated by Δ. If the image of the supported point is seen from a direction different from the viewing direction of the image of the supported point indicated by △ and □, such as the supported point indicated by ○, the amount of deviation of the center point of the substrate support surface However, if the viewing direction is constant, the amount and direction of displacement are the same for the substrate support surface of the support member that supports any supported point, and the relative positional relationship between the plurality of supported points A plurality of supporting members can be arranged at positions having the same relative positional relationship, and a substrate supporting apparatus capable of supporting these supported points is obtained.

The recognition direction can be made constant by the recognition direction limiting device and the recognizable light limiting device configured by the blocking filter, the incident light limiting cylinder, and the like described in the above embodiments. For example, in the embodiment shown in FIGS. 1 to 6, even if the half mirror 60 is arranged on a broadly divided bisection plane, the images of a plurality of supported points are parallel due to the limitation of the viewing direction by the blocking filter 64. The backup pin 16 can be arranged at a position that can be seen from the direction and has the same relationship as the relative positional relationship between the plurality of supported points. Because the blocking filter 64 limits the recognition direction of the supported point and the substrate support surface 44 to a direction perpendicular to them, the substrate support surface 44 and the portion on which the backup pin 16 of the support surface 14 is placed Are positioned on the same optical path in the recognition direction, and the backup pin 16 is separated from the line of intersection between the supported surface 152 and the support plane 154 in the same manner as when the half mirror 60 is positioned on the narrowly divided bisection plane. Can be arranged at a position equal to the distance from the line of intersection of the supported points, and the holding of the printed circuit board 86 and the support base 12 by the holding device can be simplified.
Similarly, when the support member placement point is indicated by projecting light from the projector, similarly, if the half mirror is positioned on a broadly divided bisection plane, a plurality of projection directions can be obtained by making the projection direction constant. It is possible to indicate the arrangement points of the supporting members that respectively support the supported points. For example, in the embodiment shown in FIGS. 8 and 9, the laser beam projection direction of the laser pointer 256 is constant, and the half mirror 252 can be positioned on a broadly divided bisection plane.

  As shown in FIG. 19, the same applies to the case where the angle formed by the supported surface and the support plane is an acute angle, and when the half mirror is arranged on a bisected plane in a narrow sense between the supported surface and the support plane. The distance from the intersection of the supported surface and the support plane at the center of the substrate support surface where the image overlaps the image of the supported point is the same regardless of the direction in which the image of the supported point is recognized. The support member can be disposed at a position equal to the distance of the supported point from the intersection line and to support the supported point. Further, when the half mirror is arranged on a broadly divided bisection plane, if the recognition direction of each image of a plurality of supported points is different, the substrate support appears to overlap the image of the supported point. The amount of deviation at the center of the surface is different, and the support member cannot be placed at a position having the same relative positional relationship as the relative positional relationship between the plurality of supported points. And the support member can be disposed at a position where the supported point can be supported.

  As shown in FIG. 20, the same applies to the case where the angle formed by the supported surface and the support plane is an obtuse angle, and when the half mirror is arranged on a narrowly divided bisection plane between the supported surface and the support plane. Is a position where the center of the substrate support surface is located at a position where the distance from the line of intersection between the supported surface and the support plane is equal to the supported point even when each image of the plurality of supported points is viewed from different directions. A support member can be disposed. Although illustration is omitted, when the half mirror is arranged on a broadly divided bisection plane, a plurality of supporting members can be arranged at arrangement points corresponding to the supported points by making the recognition direction constant. .

  In each of the above embodiments, the image formed by the transmitted light that passes through the half mirror and the image formed by the reflected light by the reflection of the half mirror are recognized by the operator looking directly. However, for example, an imaging device may be used as the recognition device, and the recognition device may be recognized by imaging. As the imaging device, for example, a CCD camera which is a kind of surface imaging device is used. For example, when the image capturing apparatus recognizes an image in the support apparatus 8 shown in FIGS. 1 to 6, the image capturing apparatus is arranged so that the image capturing surface thereof is parallel to the support base holding unit 70 and the image capturing axis is perpendicular to the image capturing apparatus. The image pickup device is moved to an arbitrary position in a plane parallel to the support surface 14 by the apparatus, and images formed through the half mirror 60 are sequentially picked up. An image obtained by imaging by the imaging device is displayed on the display device, and the operator puts the backup pin 16 at a position where the substrate support surface 44 is displayed while overlapping the supported point while viewing the display. According to the imaging device, the worker's visible range is limited to the imaging range. The imaging device itself functions as a recognition point limiting device, a recognition direction limiting device, and a recognizable light limiting device. For example, as shown in FIGS. 13 and 14, a supported surface 152 and a support plane 154 are provided in parallel. In such a case, by providing the imaging device so that the imaging axis is parallel to the supported surface 152 and the supporting plane 154, the recognition direction is limited, and the periphery of the supported point and the substrate supporting surface are viewed from a direction perpendicular to them. be able to. Further, the light path from the supported point until the light reflected in the direction of the normal to the supported surface enters the half mirror, and the light reflected from the substrate support surface in the direction of the normal to the support plane is the half mirror. By making the optical path to enter the same length, the imaging device can take an image with both the periphery of the supported point and the substrate support surface in focus, and the coincidence can be accurately determined. Can be judged.

  A mark representing the center of the field of view may be recognized together with the image. For example, when an image is recognized by the imaging device, a mark representing the imaging center, for example, a crosshair is displayed together with the image obtained by imaging at the center of the display screen of the display device, and the imaging device supports The supported surface is imaged with the point coincident with the imaging center. Then, the backup pin is placed on the support surface so that the center of the substrate support surface is located at the intersection of the cross lines. When a mark representing the imaging center is displayed, the supported surface and the support plane may be alternately illuminated so that only one image is captured and displayed.

  Even when an operator recognizes an image directly with eyes, it is effective to provide a visual field center mark. For example, in the embodiment shown in FIGS. 10 to 12, a crosshair is provided at the center of the half mirror 332, or in each embodiment shown in FIGS. 13 and 14, a crosshair is provided at the center of the half mirrors 402 and 504. The half mirrors 332, 402, and 504 are moved to a position where the line and the supported point coincide with each other, and the backup pin 16 is placed on the support surface 14 at a position where the center of the substrate support surface 44 coincides with the cross line. In this case, since the supported point is taught by a crosshair, the viewing range can be set relatively wide, and it is easy to find the supported region. Further, as in each of the support devices 400 and 470 shown in FIGS. 13 and 14, the support surface 14 and the supported surface 152 are illuminated by the illumination devices 440 and 442, respectively, and are particularly effective when the illumination is selectively performed. is there. Since the position of the supported point is stored by the cross line and the pin placement point is accurately taught, the backup pin can be accurately placed even if the supported point is not recognized when the backup pin 16 is placed. is there. By irradiating only the supported surface 152 and only the supporting surface 14 with light, the backup pin 16 can be arranged by searching for the supported point without being disturbed by the image of the other surface.

  If the cylinder is used to limit the position, recognizable direction, and recognizable light for recognizing the image of the supported point and the image of the substrate support surface of the support member, the position can be fixed if the cylinder is long. Even if the distance between the worker facing the holding device provided and the tip of the tube, that is, the end opposite to the side on which the worker looks into the tube is long, the distance between the looking side end and the worker Is not too far away and easy to look into. In this case, for example, if a plurality of cylinder members are slidably fitted to each other and the cylinder can be expanded and contracted, the cylinder is contracted when the cylinder is moved closer to the operator, By extending the cylinder when moved to the away side, the operator can always look into the cylinder at substantially the same position in the direction parallel to the center line of the cylinder. The holding member that holds the cylinder may be a member that can be expanded and contracted.

  In addition, when using a cylinder, the half mirror is not limited to be provided together with the cylinder, and as with a case where no cylinder is used, the entire supported surface and the entire supporting surface can be viewed simultaneously as a single large half mirror. Also good.

  Further, in each of the embodiments shown in FIGS. 1 to 6 and FIG. 7, the cutoff filters 64 and 202 may be omitted.

  In addition, as shown in each embodiment shown in FIGS. 1 to 6 and FIG. 7, if the holding device 62 can be folded into a more compact state in the use state in the non-use state, the storage device etc. For example, in the holding device 62 shown in FIG. 1, the support holding unit 70 and the mirror holding unit 72 of the second holding member 68 and the first holding member 66 are further folded and combined. Also good. 8 to 9, FIG. 10 to FIG. 12, FIG. 13 and FIG. 14, the holding device may be configured to be folded into a more compact state in the use state when not in use. In addition, in each embodiment shown in FIGS. 1 to 6 and FIG. 7, the holding device may be left in use, and the support base holding portion and the substrate mounting surface may be fixedly provided at a right angle.

  Further, as in each of the support devices 400 and 470 shown in FIGS. 13 and 14, when the printed circuit board is held in a horizontal and downward state, negative pressure is supplied to the board holding portion and formed on the board mounting surface. Air may be sucked from the negative pressure supply hole so that the circuit board is attracted and held by the negative pressure on the board mounting surface.

  In addition, the assembly method and support device according to the present invention assembles a device that supports one of the both sides of the printed circuit board on which the electronic circuit component is not mounted as a supported surface by a support member, and supports the assembly. can do. For example, a wiring pattern is formed on the surface of the printed circuit board on which the electronic circuit component is not mounted, and the mounting of the electronic circuit component is planned. There is a surface on the side of the printed circuit board on which the electronic circuit component is not mounted on only one surface of the printed circuit board. When it is desirable to support the circuit board on which the wiring pattern is formed, avoiding the wiring pattern, or when it is necessary to support it without the wiring pattern, the state of the wiring pattern formation A wiring pattern display body having a display surface representing the circuit board is used in place of the component arrangement display body for the assembly of the substrate support device and the assembly support in the same manner as the component arrangement display body. Even if the electronic circuit component of the printed circuit board is not mounted and the wiring pattern is not formed, for example, when there is at least one of a convex part and a concave part and it is necessary to support the printed circuit board avoiding it, An uneven display body having a display surface representing the unevenness of the supported surface of the printed circuit board is used to support the assembly and assembly of the board support device in the same manner as the component arrangement display body, instead of the component arrangement display body. Each of the wiring pattern display body and the concavo-convex display body is a supported surface state display body that represents the state of the supported surface of the printed circuit board. As the supported surface state display body, for example, the printed circuit board itself or the supported surface of the printed circuit board An image representing can be used. The component arrangement display body is also a kind of supported surface state display body.
