(Embodiment 1)
Hereinafter, a plate-like member arrangement jig according to Embodiment 1 of the present invention and a plate-like member arrangement method using the plate-like member arrangement jig will be described with reference to the drawings.

  FIG. 1 is a perspective view of a plate-like member placement jig 1 according to Embodiment 1 and a first plate-like member 21 and a second plate-like member 23 that are placed by using this plate-like member placement jig 1. It is. For easy understanding, XYZ is the horizontal direction of the first plate member, the X axis is the depth direction of the first plate member, and the Z axis is the vertical direction of the first plate member. Set coordinates and refer to them as appropriate.

  The first plate-like member 21 and the second plate-like member 23 to be arranged are a glass substrate used for manufacturing a liquid crystal display, a panel substrate used for manufacturing a touch panel, and an electronic circuit on which electronic components are mounted. Any plate-like material such as a substrate may be used as long as it is superimposed. In the following description, for ease of understanding, a circuit board on which an electronic circuit is mounted will be described as an example.

  The plate-like member arrangement jig 1 according to the present embodiment is used for the operation of arranging the first and second circuit boards 21 and 23 with their positions in the plane direction aligned, and includes a base plate 11 and a spring. It comprises pins 15a and 15b.

  The base plate 11 is made of a rectangular plate material, and a recess 12 is formed on the upper surface thereof. The recess 12 is substantially the same shape as the first circuit board 21 and has a slightly larger outer shape. Further, the depth of the recess 12 (the distance from the upper surface of the base plate 11 to the bottom of the recess 12) is smaller than the thickness of the first circuit board 21.

  When the first circuit board 21 and the second circuit board 23 are stacked, the upper portion of the first circuit board 21 is inserted into the recess 12 so as to protrude upward. By inserting the concave portion 12, the position of the first circuit board 21 with respect to the base plate 11 is determined.

  Engaging portions 13 a and 13 b are formed in the recess 12. The engaging portions 13a and 13b are formed at point-symmetrical positions (diagonal positions) around the central portion of the bottom surface of the recess 12. As shown in an enlarged view in FIG. 3, the engaging portions 13 a and 13 b are configured by tapered (conical) depressions. The tapered tips 13t of the engaging portions 13a and 13b are arranged with high positional accuracy at predetermined positions.

The spring pins 15a and 15b shown in FIG. 1 respectively pass through the alignment through holes 22a and 24a, 22b and 24b formed in the circuit boards 21 and 23 to be arranged, and the tips thereof are engaging portions 13a. , 13b. Each spring pin 15a, 15b is formed in a cylindrical shape having a spring action in the radial direction, and as shown in an enlarged view in FIG. The tips 16t of the spring pins 15a and 15b are adjusted so as to be positioned on the cylindrical central axis 17 of the spring pins 15a and 15b. The tapered shape of the distal end portion 16 of the spring pins 15a and 15b is substantially the same as the tapered shape of the engaging portions 13a and 13b.
For example, as illustrated in FIGS. 4A and 4B, the spring pins 15a and 15b are formed by rounding an elastic plate into a cylindrical shape and forming a straight slit 41 or a corrugated slit 44 in the radial direction. It consists of a pin with spring action.

  As shown in FIG. 1, the first circuit board 21 is a rectangular plate and has substantially the same outer shape as the recess 12 of the base plate 11. Further, the first circuit board 21 has a thickness larger than the depth of the recess 12. For this reason, as shown in FIG. 2, the first circuit board 21 is accommodated in the recess 12 while slightly protruding from the recess 12.

  Further, the first circuit board 21 has first through holes 22a and 22b. The first through holes 22a and 22b are formed at point-symmetrical positions (diagonal positions) with the central portion of the first circuit board 21 as the center. When the first circuit board 21 is inserted into the recess 12, the first through holes 22a and 22b are located at positions where the centers coincide with the centers 13t of the engaging portions 13a and 13b, for example, a precision press or the like. Is formed in a circular shape. The first through holes 22a and 22b are also aligned with high accuracy with respect to each part (circuit, terminal, pad, element) and the like on the first circuit board 21.

The second circuit board 23 is also a rectangular plate material like the first circuit board 21, and has substantially the same shape and size as the first circuit board 21.
Second through holes 24 a and 24 b are formed in the second circuit board 23. The second through holes 24 a and 24 b are formed at point-symmetrical positions (diagonal positions) around the center of the second circuit board 23. Each second through-hole 24a, 24b is located at a position where the center thereof coincides with the tip 13a of the engaging portion 13a, 13b when the second circuit board 23 is inserted into the recess 12, for example, a precision press or the like. Is formed in a circular shape. The second through holes 24 a and 24 b are also aligned with high accuracy with respect to each part (circuit, terminal, pad, element) and the like on the second circuit board 23.

  The first through holes 22a, 22b and the second through holes 24a, 24b are formed to have the same diameter and slightly smaller than the unloaded diameter of the spring pins 15a, 15b.

Next, a method of aligning and fixing the first circuit board 21 and the second circuit board 23 using the plate-shaped member arrangement jig 1 having the above-described configuration will be described. In order to facilitate understanding, an example in which the first circuit board 21 and the second circuit board 23 are directly stacked will be described here.
First, the first circuit board 21 is inserted into the recess 12 of the base plate 11. Thereby, the engaging portions 13a and 13b and the first through holes 22a and 22b of the first circuit board 21 are roughly aligned (substantially overlap).

  Next, as shown in FIG. 5A, the second circuit board 23 is placed on the first circuit board 21. At this time, adjustment is made so that the second through holes 24 a and 24 b of the second circuit board 23 are positioned on the first through holes 22 a and 22 b of the first circuit board 21.

Subsequently, as shown in FIG. 5B, the second through-holes 24a and 24b of the second circuit board 23 and the first through-holes 22a and 22b of the first circuit board 21 are disposed upward (FIG. 1). The spring pins 15a and 15b are press-fitted from above in the Z-axis direction. As the spring pins 15a and 15b progress, the positions of the first circuit board 21 and the second circuit board 23 in the surface direction (XY direction) are finely adjusted.
Further, the spring pins 15a and 15b are deformed into a radially contracted state by being press-fitted.

  Further, when the spring pins 15a and 15b are inserted downward in the figure (downward in the Z-axis direction in FIG. 1), as shown in FIG. 5C, the distal end portions 16 of the spring pins 15a and 15b are engaged with the engaging portions. The tip portions 16 of the spring pins 15a and 15b are moved along the taper shapes of the engaging portions 13a and 13b, and finally the tips 16t of the spring pins 15a and 15b and the engaging portions 13a are brought into contact with 13a and 13b. , 13b and the tip 13t coincide with each other to stop.

The spring pins 15a and 15b are in a state of being press-fitted into the circular first and second through holes 22a, 22b, 24a and 24b. Therefore, in the process of inserting the spring pins 15a and 15b, the centers of the first through holes 22a and 22b and the second through holes 24a and 24b are aligned with each other. The mutual alignment with the second circuit board 23 is completed.
Further, the tips 16t of the spring pins 15a and 15b are located on the center axis 17 of the spring pins 15a and 15b, and the tips 16t coincide with the centers 13t of the engaging portions 13a and 13b. For this reason, the first circuit board 21 and the second circuit board 23 are also aligned with the base plate 11.

In this state, the first circuit board 21 and the second circuit board 23 are fixed to each other by an adhesive, welding, screwing, or the like.
Further, if necessary, it is also positioned with respect to other members (that is, the first circuit board 21 and the second circuit board 23) that are positioned and positioned with respect to the base plate 11. ) Is also fixed.

Thereafter, the spring pins 15 a and 15 b are pulled out from the first circuit board 21 and the second circuit board 23, and the integrated first circuit board 21 and second circuit board 23 are taken out from the recess 12.
Thereafter, if necessary, the integrated one circuit board 21 and the second circuit board 23 are fixed to an arbitrary housing or the like with fixing screws or the like.

  As described above, by using the plate-like member placement jig 1 of the present embodiment, the first circuit board 21 is placed in the recess 12 of the base plate 11 and the second circuit board 23 is placed thereon. The first circuit board 21 and the second circuit board 23 are raised by a simple operation of inserting the spring pins 15a and 15b into the two through holes 22a, 22b, 24a and 24b. It can be aligned with accuracy.

  The positions of the first through holes 22a and 22b are also adjusted with respect to each part (wiring, terminal, pad, element, etc.) in the first circuit board 21. Similarly, the positions of the second through holes 24a and 24b are adjusted with respect to each part (wiring, terminal, pad, element, etc.) in the second circuit board 23. Therefore, by aligning the first circuit board 21 and the second circuit board 23 with respect to the first through holes 22a and 22b and the second through holes 24a and 24b, the first circuit board 21 can be aligned. The alignment of each part (terminal, pad, etc.) with each part (terminal, pad, etc.) on the second circuit board 23 is also completed.

  Further, the first circuit board 21 and the second circuit board 23 are also aligned with the base plate 11, and alignment with other members aligned with the base plate 11 can be achieved at the same time.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation and application are possible.

  For example, in the above description, the recess 12 is formed so as to be shallower than the thickness of the first circuit board 21, but it may be formed to be the same as or deeper than the thickness of the first circuit board 21. When the depth of the recess 12 is deeper than the thickness of the first circuit board 21, a part of the second circuit board 23 is also inserted into the recess 12, which facilitates alignment. In this case, it is desirable to provide a notch or the like in the recess 12 in order to facilitate insertion and removal of the substrate from the recess 12.

  Further, in the present embodiment, description has been made by taking as an example the alignment of two circuit boards in the plane direction, but the number of plate-like members to be aligned is arbitrary, and three or more circuits are provided. Substrate alignment is also possible. In this case, the spring pins 15a and 15b are set to appropriate lengths.

  Moreover, although the example which forms the two holes 22a and 22b and 24a and 24b in the 1st and 2nd board | substrates 21 and 23 was demonstrated, respectively, the number of the holes for the alignment formed in each plate-shaped member is It is optional and may be three or more. Further, it is desirable to arrange the alignment holes at positions apart from each other, and it is desirable to arrange them at diagonal positions as in the above embodiment. However, according to the shape of the plate-like member, the structure / parts arrangement, etc., holes can be appropriately provided at positions where alignment is easy.

  Moreover, although the external shape of the recessed part 12 of the base board 11 was made into the rectangle, this Embodiment is not limited to this. That is, it is possible to select the shape of the outer shape of the opening of the recess in accordance with the shape of the substrate desired to be aligned, such as a trapezoidal shape or other polygonal shapes.

  Moreover, although the spring pin was illustrated as an insertion member inserted in the hole for position alignment formed in the plate-shaped member, it is not limited to this. For example, instead of a spring pin, a thermal expansion pin can be employed as an insertion member. A thermal expansion pin fixes a board | substrate by applying the external pressure by thermal expansion around a hole by applying a fixed amount of heat after inserting in the hole for position alignment of a plate-shaped member.

(Embodiment 2)
In the above embodiment, the positioning portion for determining the position of the plate-like member with respect to the base plate 11 (plate-like member placement jig 1) is not limited to the concave portion 12, but the plate with respect to the base plate 11 and the engaging portions 13a and 13b. It is optional if the position of the member can be fixed. For example, the positioning portion that determines the position of the plate-like member may be a wall-like configuration that protrudes upward from the upper surface of the base plate 11 and surrounds the outer shape of the plate-like member to be aligned. As an example, a plate-shaped member arrangement jig provided with a positioning portion that can position at least two adjacent sides of a plate-shaped member will be described with reference to FIG.

  The plate-like member arrangement jig 50 in the second embodiment is similar to the plate-like member arrangement jig 1 in the first embodiment, and the engaging portions 13a and 13b formed on the base plate 11 and the first circuit. The front end 16 penetrates through the first through holes 22a, 22b provided in the substrate 21 and the second through holes 24a, 24b provided in the second circuit board 23, and the engaging portions 13a, 13b. It consists of engaging spring pins 15a and 15b.

  Unlike the first embodiment, the base plate 11 has one wall (first positioning portion) 51 in the X-axis direction and one wall (second positioning portion) 52 in the Y-axis direction. Is formed. The first positioning portion 51 and the second positioning portion 52 are formed adjacent to each other, and both are arranged so as to form an angle suitable for the substrate to be aligned, in this embodiment, an angle of approximately 90 degrees. The

  The first positioning portion 51 and the second positioning portion 52 are formed of a plate material having an elongated rectangular shape that protrudes from the upper surface of the base plate 11 in the Z-axis direction. The height y1 of the first positioning portion 51 and the height y2 of the second positioning portion 52 are formed to be lower than the thickness x of the plate of the first circuit board 21. Thereby, the 1st positioning part 51 and the 2nd positioning part 52 can position the 1st circuit board 21 with a small area.

  The length l of the first positioning portion 51 is arbitrary, but is, for example, substantially the same as the length m of the first circuit board 21 in the X-axis direction, and the length h of the second positioning portion 52 is also the same. For example, the length is substantially the same as the length g of the first circuit board 21 in the Y-axis direction.

  The first positioning part 51 is engaged with the side in the X-axis direction of the first circuit board 21, and the second positioning part 52 is engaged with the side in the Y-axis direction of the first circuit board 21. By doing so, the first circuit board 21 is positioned on the base plate 11. The length l of the first positioning portion 51 and the length m of the first circuit board 21 in the X-axis direction are substantially the same, and the length h of the second positioning portion 52 is the same as the first length. Since the length g of the circuit board 21 in the Y-axis direction is substantially the same, reliable alignment is possible.

  Then, spring pins 15a and 15b are provided in the second through holes 24a and 24b formed in the second circuit board 23 and the first through holes 22a and 22b formed in the first circuit boards 22a and 22b. The first circuit board 21 and the second circuit board are engaged by engaging the engaging portions 13a and 13b formed on the base plate 11 with the tapered portions of the tip portions 16 of the spring pins 15a and 15b. 23, and the first circuit board 21 and the second circuit board 23 and the base plate 11 can be aligned.

  The length l of the first positioning part 51 and the length m of the first circuit board 21 in the X-axis direction, and the length h of the second positioning part 52 and the Y-axis of the first circuit board 21 The example in which the length g in the direction is substantially the same has been described. However, the length l of the first positioning portion 51 may be shorter or longer than the length m of the first circuit board 21 in the X-axis direction. In addition, the length h of the second positioning portion 52 may be longer or shorter than the length g of the first circuit board 21 in the Y-axis direction. If the length of the positioning portion is shorter than the length of the first circuit board 21, the cost of the material is reduced, and if it is longer, the positioning is surely performed.

  Moreover, although the height y1 of the 1st positioning part 51 and the height y2 of the 2nd positioning part 52 demonstrated the example formed smaller than the thickness x of the 1st circuit board 21, height y1 and It is also possible to form the height y2 larger than the thickness x.

  Furthermore, although the 1st positioning part 51 and the 2nd positioning part 52 each demonstrated the example comprised by one member, it is not limited to such a member. In other words, the first positioning portion 51 and the second positioning portion 52 can be formed of a slit-like member. Thereby, even if it is a board | substrate which has a shape where one side is long, it becomes possible to align with few members.

  In the present embodiment, an example in which the first positioning portion 51, the second positioning portion 52, and the engaging portions 13a and 13b are provided on one base plate 11 has been described. Is not limited to this. You may make it provide the 1st positioning part 51 and the 2nd positioning part 52, and the engaging parts 13a and 13b on another member. By adopting such a configuration, it is possible to perform positioning according to the working environment in which the alignment work is performed and the characteristics of the substrate to be aligned.

  As described above, according to the second embodiment, it is possible to easily position the board by positioning only two adjacent sides of the first circuit board 21 by the positioning unit.

  In the first and second embodiments, the description has been made on the assumption that the substrate to be positioned has a rectangular shape, but the present embodiment is not limited to this. The substrate shape to be positioned is arbitrary.

  For example, as illustrated in FIG. 7, the first circuit board 61 and the second circuit board 63 to be aligned may have a polygonal shape.

  Also in this case, the first positioning portion 51 and the second positioning portion 52 are formed on the base plate 11. In order to perform alignment between the side 73 and the side 74 of the first circuit board 61, the first positioning unit 51 and the second positioning unit 52 are arranged to form corresponding angles.

  In the first circuit board 61 having a polygonal shape, the side 73 in the X-axis direction is aligned by the first positioning unit 51, and the side 74 in the Y-axis direction is positioned by the second positioning unit 52. . Then, spring pins 15 a and 15 b are inserted into the second through holes 64 a and 64 b of the second circuit board 63 and the first through holes 62 a and 62 b of the first circuit board 61, and formed on the base plate 11. By engaging the tip portions of the spring pins 15a and 15b with the engaging portions 13a and 13b, the first circuit board 61 and the second circuit board 63 are aligned with each other and aligned with the base plate 11. It becomes possible.

  As described above, in the present invention, the size and shape of the plate member are not particularly limited. Further, the shapes of the plate-like members to be aligned may be different. The shape and the size are not limited as long as the alignment holes can be formed at positions where the plurality of plate-like members should overlap.

(Embodiment 3)
In the first embodiment and the second embodiment, the example in which the plate-like members are brought into contact with each other and aligned and overlapped has been described. However, the present invention also applies to the case where a plurality of plate-like members are aligned at intervals. Applicable.

  Hereinafter, a third embodiment in which a first circuit board and a second circuit board are overlapped via a spacer will be described with reference to the drawings.

However, the first circuit board 21 and the second circuit board 23 are stacked via spacers 26a and 26b. The spacers 26 a and 26 b are formed of a cylindrical member having a length equal to the distance (interval) between the first circuit board 21 and the second circuit board 23. The hollow part 27a inside the spacer 26a has a diameter larger than the diameters of the through holes 22a and 24a, and the hollow part 27b inside the spacer 26b has a diameter larger than the diameters of the through holes 22b and 24b.

  In this case, in order to align the first and second circuit boards 21 and 23, the first circuit board 21 is disposed in the recess 12 provided in the base plate 11. Subsequently, spacers 26a and 26b are placed on the periphery of the first through holes 22a and 22b of the first circuit board 21, and the second circuit board 23 is placed on the placed spacers 26a and 26b. The second circuit board 23 is placed together with the second through holes 24a and 24b.

Then, the spring pin 15a is inserted in the order of the second through hole 24a, the hollow portion 27a of the spacer 26a, and the first through hole 22a from the upper side in the drawing (upward in the Z-axis direction in FIG. 8), and the spring pin 15b is inserted. , Hole 24b, hollow portion 27b of spacer 26b, and first through hole 22b are inserted in this order.
As a result, as shown in FIG. 9, the second through holes 24a and 24b of the second circuit board 23, the hollow portions 27a and 27b of the spacers 26a and 26b, and the first through holes 22a of the first circuit board 21 are provided. , 22b is penetrated through the inner periphery. Thereby, alignment of these members is performed.
When the distal end portions 16 of the spring pins 15a and 15b are engaged with the engaging portions 13a and 13b, the positioning of each portion with respect to the base plate 11 is also completed.

  Thereafter, for example, the first circuit board 21 and the spacers 26a and 26b are temporarily fixed, and the second circuit board 23 and the spacers 26a and 26b are temporarily fixed. Subsequently, it is fixed to a housing or the like as necessary.

  It may be necessary to electrically connect the first circuit board 21 and the second circuit board 23 to each other.

  As a method of connecting the first circuit board 21 and the second circuit board 23 with the spacers 26a and 26b interposed, for example, there are a connection method by soldering and a connection method by a connector.

A connection line 103 (for example, a flexible substrate) is used for connection.

  By using the plate-like member arrangement jig shown in the third embodiment, even when a spacer is provided between the substrates, the alignment in the surface direction between the substrates can be easily performed. If the method for connecting electronic circuit boards using the plate-like member placement jig of the present embodiment is used, there will be no inconveniences such as the connectors being displaced and the connectors being inclined after the boards are connected.

  Although the present embodiment has been described by taking a cylindrical spacer as an example, the present embodiment is not limited to this. That is, as shown in FIG. 12, a prismatic spacer 110 having a hollow portion is inserted between the first circuit board 21 and the second circuit board 23, and the first circuit board 21 and the second circuit board 23 are inserted. The present invention can also be applied to a structure in which a space is provided between the circuit boards 23.

  The spacer 110 has substantially the same external dimensions as the external dimensions of the first circuit board 21 and the second circuit board 23. The spacer 110 is placed so that the lower portion thereof is along the outer edge portion on the first circuit board 21. Further, on the upper part, the second circuit board 23 is placed so that the outer edge part of the spacer 110 and the outer edge part of the second circuit board 23 are along.

  The alignment of the first circuit board 21 and the second circuit board 23 with the spacer 110 interposed therebetween is performed in the same manner as the alignment of the substrate with the spacers 26a and 26b interposed.

  As a method of connecting the first circuit board 21 and the second circuit board 23 with the spacer interposed therebetween, solder is applied to the upper surface of the first circuit board 21 and the lower end portion of the spacer 110, and is welded. Solder is applied to the lower surface of the circuit board 23 and the upper end portion of the spacer 110 and welded to fix the two boards, and then the wiring is connected by connecting wires.

  Since the spacer 110 is in contact with the outer edges of the first circuit board 21 and the second circuit board 23 as compared with the spacers 26a and 26b, when the board is an electronic circuit board on which an electronic circuit is mounted, The space on the substrate surface can be used effectively.

  As described above, according to the present embodiment, even if the spacer is interposed between the first circuit board and the second circuit board, the first circuit board and the second circuit board are aligned in the plane direction. Can be easily.
