Description

  The present invention relates to a member connection structure that positions and connects a first member having a first fitting portion and a second member having a second fitting portion that is unevenly fitted to the first fitting portion. is there.

  As this type of member connection structure, the present inventor has developed a member connection structure 100 shown in FIGS. As an example, in the member connection structure 100, in a jig-type substrate inspection apparatus, as shown in FIG. 21, an inspection probe 102 is located in a probe arrangement region A with respect to a base portion 101 (one member). A plurality of pinboards 103 (the other member) are connected to each other by finely adjusting their attachment positions, and a pair of fitting cylinders 104 (one of the members) attached to the base 101 Fitting portion), a pair of fitting pins 105 (the other fitting portion) attached to the pin board 103, and attachment positions of the fitting pins 105 to the pin board 103 are orthogonal to each other. An adjustment mechanism 106 for fine adjustment along the X-axis and Y-axis directions is provided.

  Specifically, an opening 101b for wiring to a plurality of probes 102 arranged in the probe arrangement area A is formed in the upper wall 101a of the base portion 101 to which the pin board 103 is attached. . The pair of fitting cylinders 104 are attached to positions on the upper wall 101a along the X direction and spaced apart with the opening 101b interposed therebetween. The inner diameter of the fitting cylinder 104 is defined as a length that allows the fitting pin 105 to be inserted with very little rattling.

  The pair of fitting pins 105 are inserted into through holes 103a formed in the pin board 103 as shown in FIG. 23 at positions corresponding to the pair of fitting cylinders 104 in the pin board 103 as shown in FIG. It is erected in a standing state. As an example, each fitting pin 105 has a male screw portion 105a formed on the outer peripheral surface of one end portion (the upper end portion in the figure) and a position slightly spaced from the male screw portion 105a on the outer peripheral surface (the male screw portion 105a). The plate-like positioning block 107 having a constant thickness and a square shape in plan view (see FIG. 22) extends from the fitting pin 105 to the other end (the lower end in the drawing). It is attached in a state orthogonal to the vertical direction. In addition, each fitting pin 105 is inserted into the through hole 103a from one side facing the base part 101 of the pin board 103 and protrudes from the non-facing face of the pin board 103 to the base part 101. A nut 109 is screwed in a state where a washer 108 is interposed in a male screw portion 105 a formed at one end portion, so that the pin board 103 is erected. Each fitting pin 105 has an outer diameter smaller than the inner diameter of the through hole 103a.

  With this configuration, when the nut 109 is screwed into the male screw portion 105a, the lip portion of the through hole 103a in the pin board 103 is sandwiched between the nut 109 and the positioning block 107, so that the inside of the through hole 103a. The movement of the fitting pin 105 is restricted. That is, the fitting pin 105 is fixed to the pin board 103. On the other hand, when the nut 109 is loosened, the pin board 103 is released from being pinched by the nut 109 and the positioning block 107, so that the movement of the fitting pin 105 in the through hole 103a (the length of the fitting pin 105). Movement in a direction perpendicular to the direction).

  As shown in FIG. 22, the adjustment mechanism 106 includes an L-shaped positioning block 110 and a pressing portion 111 in a plan view. As shown in FIG. 21, the surface facing the base portion 101 of the pin board 103 (the lower surface in the figure). ). Specifically, as shown in FIG. 22 as an example, the pressing portion 111 is fixed to a fixed block 112 fixed on an opposing surface of the pin board 103, and is screwed to the fixed block 112 in a state parallel to the pin board 103. And a bolt 113 whose tip protrudes from the fixed block 112. Further, as shown in FIG. 22, the positioning block 110 and the pressing portion 111 are arranged such that the fitting pin 105 and the intersection D of the positioning reference surfaces B and C in the positioning block 110 are arranged in this order on the extension of the axis of the bolt 113. It arrange | positions so that it may be located in. In this case, it is defined in advance that the reference plane B is parallel to the Y axis and the reference plane C is parallel to the X axis.

  With this configuration, by screwing the bolt 113 into the fixing block 112, the positioning block 107 is moved in the direction of the positioning block 110 at the tip of the bolt 113 protruding from the fixing block 112, and the surface of the positioning block 107 facing the reference surface B The position of the positioning block 107 on the pin board 103, that is, the positioning, is obtained by bringing E into contact with the reference surface B and contacting the reference surface C of the positioning block 107 with the reference surface C. The position of the fitting pin 105 on the pin board 103 is defined via the block 107.

  Moreover, in this member connection structure, as shown in FIG. 22, by applying a gap adjustment technique using a gap adjustment sheet disclosed in Patent Document 1 below, between each of the reference surfaces B and E described above, and A configuration is employed in which the position of the fitting pin 105 on the pin board 103 is finely adjusted by appropriately inserting a gap adjusting sheet 114 between the reference surfaces C and F. Specifically, the number of interval adjusting sheets 114 sandwiched between the reference surface B of one positioning block 110 and the facing surface E of one positioning block 107 is increased, and the other positioning block is increased by this increased number of sheets. By reducing the number of spacing adjustment sheets 114 sandwiched between the reference surface B 110 and the facing surface E of the other positioning block 107, the positions of the fitting pins 105 on the pin board 103 are aligned along the X-axis direction. Thus, it is possible to shift by the number of changed sheets of the interval adjusting sheet 114 (specifically, the distance obtained by multiplying the changed number of sheets by the thickness of the interval adjusting sheet 114).

  Further, by increasing or decreasing the number of interval adjustment sheets 114 sandwiched between the reference surface C of each positioning block 110 and the facing surface F of each positioning block 107, the position of the pin board 103 with respect to the base portion 101 is set in the Y-axis direction. Accordingly, it is possible to shift the distance adjustment sheet 114 by the number of sheets to be changed. Therefore, according to this member connection structure, each fitting pin 105 of the pin board 103 is inserted into the corresponding fitting cylinder 104 of the pair of fitting cylinders 104 attached to the base portion 101. Thus, the position of the pin board 103 with respect to the base portion 101 can be finely adjusted and connected in the X-axis direction and the Y-axis direction.

  However, this member connection structure 100 has the following problems to be solved. That is, in this member connection structure 100, the number of the interval adjustment sheets 114 is changed, and the mounting position of the pin board 103 as the other member with respect to the base portion 101 as one member is changed. However, since the operation of changing the number of the interval adjustment sheets 114 is a fine operation and takes time, this member connection structure 100 takes time to adjust the mounting position of the other member with respect to one member. There is a problem to be solved. Further, by screwing the bolt 113 into the fixed block 112, the positioning block 107 is moved in the direction of the positioning block 110 at the tip of the bolt 113, and between the reference surface B and the facing surface E and between the reference surface C and the facing surface F. Since the positioning block 107 is pressed against the positioning block 110 with the gap adjusting sheet 114 interposed therebetween, the position of each positioning block 107 on the pin board 103 according to the screwing condition of the bolt 113, and consequently The position of each fitting pin 105 on the pin board 103 changes slightly.

  Hereinafter, with reference to the accompanying drawings, an embodiment of a member connection structure for connecting a first member and a second member by fitting them in a concave-convex manner will be described. In this example, as an example, a member connection structure 1 is used as an example in which a base part 2 in a jig-type board inspection apparatus is used as a first member, and a pin board 3 as a second member is connected to the base part 2 by concave and convex fitting. I will give you a description. In this case, the pin board 3 is provided with a plurality of probes 4 that come into contact with a plurality of contact points defined in advance on a substrate to be inspected by a substrate inspection apparatus. Further, in the base portion 2, a function for supplying a test signal to the inspection target substrate to be inspected by the substrate inspection apparatus via the probe 4, which occurs on the inspection target substrate due to the supply of the test signal. An electric circuit (not shown) having a function of detecting a signal through the probe 4 and a function of determining the quality of the inspection target substrate based on the detected signal is accommodated.

  As shown in FIG. 1, the member connection structure 1 is configured such that the mounting position of the pin board 3 in which a plurality of probes 4 for inspection are erected in the probe installation area A with respect to the base portion 2 is finely adjusted. A pair of first connecting members 5 attached to the surface of the base portion 2, a pair of second connecting members 6 attached to the surface of the pin board 3, and the base portion 2. A plurality of first reference holes 7 formed in a first arrangement defined in advance in each attachment position G of the pair of first connection members 5 and each attachment position H of the pair of second connection members 6 in the pin board 3. And a plurality of second reference holes 8 formed in a predetermined third arrangement.

  In this case, as shown in FIG. 3, the plurality of first reference holes 7 are composed of a pair of first holes 11 arranged along the Y direction as the first direction, and an even number of four or more is formed. Has been. In this example, as an example, the first reference hole 7 is formed with four (four sets) of first reference holes 7a, 7b, 7c, and 7d as shown in FIG. Further, the pair of first holes 11 constituting one first reference hole 7 has the same diameter and is defined at the same interval.

  Further, as shown in FIG. 5, the first array of the plurality of first reference holes 7 has a center point Pa, a line segment connecting each pair of first holes 11 of the first reference holes 7a, 7b, 7c, 7d. In the XY orthogonal coordinate system in which Pb, Pc, and Pd have the first reference point O1 defined at the mounting position G of the base portion 2 as a virtual origin and one axis line (Y axis) is parallel to the Y direction, It is defined to be symmetrical with respect to at least one of the one axis (Y axis) and the other axis (X axis) and to be point symmetric with respect to the first reference point O1. A pair of female screw holes 12 for fixing the first connecting member 5 to the mounting position G are formed at each mounting position G of the base portion 2.

  The plurality of second reference holes 8 are arranged along the Y direction as the first direction as shown in FIGS. 4 and 14 in a state where the base portion 2 and the pin board 3 are connected as shown in FIG. The paired third holes 13 are formed in an even number of 4 or more. In this example, as an example, the second reference hole 8 is formed with four (four sets) of second reference holes 8a, 8b, 8c, and 8d, as shown in FIG. Further, the pair of third holes 13 constituting one second reference hole 8 has the same diameter and is defined at the same interval.

  Further, as shown in FIG. 13, the third arrangement of the plurality of second reference holes 8 has center points Qa, of line segments connecting the pair of third holes 13 of the second reference holes 8a, 8b, 8c, and 8d. Qb, Qc, Qd are in a XY orthogonal coordinate system in which the second reference point O2 defined at the mounting position H of the pin board 3 is a virtual origin, and one axis (Y axis) is parallel to the Y direction. It is defined to be symmetrical with respect to at least one of the one axis (Y axis) and the other axis (X axis) and to be point symmetric with respect to the second reference point O2. A pair of female screw holes 14 for fixing the first connecting member 5 to the mounting position G are formed at each mounting position H of the pin board 3.

  As shown in FIGS. 1 and 3, the pair of first connecting members 5 includes a first plate body 21 and a first fitting portion 22. As an example, the first plate body 21 is formed in a rectangular parallelepiped having a rectangular shape in plan view and a uniform plate thickness. The 1st fitting part 22 is comprised by the cylindrical body erected at right angles to the surface of the 1st board 21 as an example, and functions as a fitting recessed part. The first plate 21 has a one-to-one correspondence with a plurality of (four in this example) first reference holes 7 formed in a first arrangement at the attachment position G of the base portion 2 to which the first connecting member 5 is attached. The same number (four) of first positioning holes 23 as the first reference holes 7 are formed in the second arrangement. Each first positioning hole 23 includes a pair of second holes 24, and each second hole 24 is formed to have the same diameter (the same inner diameter) as the pair of first holes 11 constituting the first reference hole 7. . Further, the first plate 21 has a first elongated hole 25 used for fixing the first connecting member 5 to the base portion 2 in a pair of female screw holes 12 formed at the mounting position G of the base portion 2. Correspondingly, a pair is formed. In this case, the first long hole 25 is formed as a long hole along the other axis (X axis).

  In addition, as shown in FIG. 6, the second arrangement of the plurality of first positioning holes 23 includes one of the plurality of first positioning holes 23 and one of the plurality of first reference holes 7. The other first positioning hole 23 of the plurality of first positioning holes 23 corresponds to the corresponding first reference hole of the plurality of first reference holes 7 in a state in which the corresponding first reference hole 7 is matched. 7 is separated by a first unit length ΔLx0 by a different distance in a second direction (X direction) orthogonal to the arrangement direction (Y direction) of the pair of second holes 24 constituting one first positioning hole 23. It is specified in the array.

  Specifically, in this example, as shown in FIG. 6, in a state where the first positioning holes 23a are aligned with the corresponding first reference holes 7a, the first positioning holes 23b are formed in the corresponding first reference holes 7b. On the other hand, they are spaced apart by a distance Lx1 (= ΔLx0) in the second direction (X direction). Further, in this state, the first positioning holes 23c are disposed away from the corresponding first reference holes 7c by a distance Lx2 (= Lx1 + ΔLx0 = 2 × ΔLx0) in the second direction (X direction). One positioning hole 23d is disposed away from the corresponding first reference hole 7d by a distance Lx3 (= Lx2 + ΔLx0 = 3 × ΔLx0) in the second direction (X direction).

  Further, as shown in FIG. 6, each first connecting member 5 has a first fitting portion 22 in a state in which the first positioning hole 23 a is attached to the base portion 2 so as to coincide with the corresponding first reference hole 7 a. The fitting center with a later-described second fitting portion (fitting portion formed on the second connecting member 6) is configured to coincide with the first reference point O1. In this example, the 1st fitting part 22 is comprised by the cylindrical body as mentioned above, and the 2nd fitting part does not have backlash in the 1st fitting part 22 comprised by the cylindrical body so that it may mention later. It is comprised in the cylindrical body inserted in a state. For this reason, since the fitting center with the 2nd fitting part in the 1st fitting part 22 turns into axis line S1 of the 1st fitting part 22 comprised by the cylindrical body, this axis line S1 is the 1st reference point. It is configured to coincide with O1 (pass through the first reference point O1).

  With this configuration, the first positioning hole 23a is made to coincide with the corresponding first reference hole 7a, and the state where the first connecting member 5 is attached to the base portion 2 (the state shown in FIG. 6) is shown in FIG. As described above, when the first positioning member 23 is attached to the base portion 2 with the first positioning holes 23b aligned with the corresponding first reference holes 7b, the first connecting member 5 is moved along the X axis by the distance Lx1. It is attached to the base part 2 in a state shifted to the left side in the figure. Further, as shown in FIG. 8, when the first linking member 5 is attached to the base portion 2 with the first positioning holes 23c aligned with the corresponding first reference holes 7c, the first linking member 5 has a distance Lx2. It is attached to the base part 2 in a state shifted only by the left side in FIG. Further, as shown in FIG. 9, when the first connecting member 5 is attached to the base portion 2 with the first positioning holes 23d aligned with the corresponding first reference holes 7d, the first connecting member 5 has a distance Lx3. It is attached to the base part 2 in a state shifted only by the left side in FIG.

  Further, in this example, as described above, the first array of the plurality of first reference holes 7 is line-symmetric with respect to at least one of the one axis (Y axis) and the other axis (X axis). Since it is defined to be point-symmetric with respect to the first reference point O1, the first connecting member 5 is rotated 180 ° from the state shown in FIGS. 6 to 9 about the axis S1 of the first fitting portion 22. By attaching to the base part 2, the base part 2 can be attached by shifting in the direction opposite to the shift direction shown in FIGS. 7 to 9. When the first connecting member 5 is rotated by 180 ° about the axis S1 of the first fitting portion 22 and attached to the base portion 2 with the first positioning hole 23a aligned with the first reference hole 7c. As a result, the axis S1 of the first fitting portion 22 coincides with the first reference point O1, and the shift amount of the first connecting member 5 with respect to the base portion 2 becomes zero. That is, it becomes the same as the attachment state shown in FIG. For this reason, the description about the aspect of this attachment is abbreviate | omitted.

  Specifically, as shown in FIG. 10, when the first connecting member 5 is attached to the base portion 2 with the first positioning hole 23b aligned with the first reference hole 7d, the attachment state shown in FIG. As described above, the first connecting member 5 is attached to the base portion 2 while being shifted to the right side in the drawing along the X axis by the distance Lx1. Further, as shown in FIG. 11, when the first positioning member 23 is attached to the base portion 2 with the first positioning hole 23c aligned with the first reference hole 7a, the first connecting member 5 is X by the distance Lx2. It is attached to the base part 2 in a state shifted along the axis by the right side in FIG. In addition, as shown in FIG. 12, when the first positioning member 23 is attached to the base portion 2 with the first positioning hole 23d aligned with the first reference hole 7b, the first connecting member 5 is X by the distance Lx3. It is attached to the base part 2 in a state shifted along the axis by the right side in FIG.

  Therefore, in this member connection structure 1, the mounting position of each first connection member 5 with respect to the base portion 2 is set to a reference position in the X direction with the position shown in FIG. 6 as the first unit length ΔLx0 unit along the X direction. It can be changed in three steps on the negative side (left side) of the X axis and in three steps on the positive side (right side) of the X axis. That is, the position where the first connecting member 5 is attached to the base portion 2 can be changed in seven stages along the X direction, including the case where the first connecting member 5 is attached to the reference position shown in FIG.

  As shown in FIGS. 1 and 4, the pair of second connecting members 6 includes a second plate body 31 and a second fitting portion 32. As an example, the second plate 31 is formed in a rectangular parallelepiped having a rectangular shape in plan view and a uniform plate thickness. The 2nd fitting part 32 is comprised by the cylindrical body erected at right angles to the surface of the 2nd plate 31 as an example, and functions as a fitting convex part. In this case, the 2nd fitting part 32 is prescribed | regulated to the diameter which can be inserted in the state without backlash in the 1st fitting part 22 comprised by the cylindrical body.

  The second plate 31 has a one-to-one correspondence with a plurality (four in this example) of the second reference holes 8 formed in a third arrangement at the attachment position H of the pin board 3 to which the second connecting member 6 is attached. The same number (four) of second positioning holes 33 as the second reference holes 8 are formed in a fourth arrangement. Each second positioning hole 33 includes a pair of fourth holes 34, and each fourth hole 34 is formed to have the same diameter (the same inner diameter) as the pair of third holes 13 constituting the second reference hole 8. . In addition, the second plate 31 has second elongated holes 35 used when fixing the second connecting member 6 to the pin board 3 in a pair of female screw holes 14 formed at the mounting position H of the pin board 3. Correspondingly, a pair is formed. In this case, the second long hole 35 is formed as a long hole along the Y axis.

  Further, in the fourth arrangement of the plurality of second positioning holes 33, one second positioning hole 33 among the plurality of second positioning holes 33 is replaced with one corresponding second reference among the plurality of second reference holes 8. In the state of being aligned with the hole 8, the other second positioning hole 33 among the plurality of second positioning holes 33 is one first relative to the corresponding second reference hole 8 among the plurality of second reference holes 8. 2 is defined as an array that is separated by a second unit length ΔLy0 by a different distance in a first direction (Y direction) parallel to the arrangement direction (Y direction) of the pair of fourth holes 34 constituting the positioning hole 33.

  Specifically, in this example, as shown in FIG. 14, in a state where the second positioning holes 33a are aligned with the corresponding second reference holes 8a, the second positioning holes 33b are formed in the corresponding second reference holes 8b. On the other hand, they are spaced apart by a distance Ly1 (= ΔLy0) in the first direction (Y direction). Further, in this state, the second positioning holes 33c are disposed away from the corresponding second reference holes 8c by a distance Ly2 (= Ly1 + ΔLy0 = 2 × ΔLy0) in the first direction (Y direction). The two positioning holes 33d are disposed away from the corresponding second reference holes 8d by a distance Ly3 (= Ly2 + ΔLy0 = 3 × ΔLy0) in the first direction (Y direction).

  Further, as shown in FIG. 14, each second connecting member 6 has the second fitting portion 32 in a state where the second positioning hole 33 a is attached to the pin board 3 with the second positioning hole 33 a matched with the corresponding second reference hole 8 a. The fitting center with the first fitting portion 22 is configured to coincide with the second reference point O2. In this example, the 2nd fitting part 32 is comprised by the column body inserted in the state without backlash in the 1st fitting part 22 comprised by the cylindrical body as above mentioned. For this reason, since the fitting center with the 1st fitting part 22 in the 2nd fitting part 32 becomes the axis line S2 of the 2nd fitting part 32 comprised by the cylindrical body, this axis line S2 is 2nd reference | standard. It is configured to coincide with the point O2 (pass through the second reference point O2).

  With this configuration, the second positioning holes 33a are aligned with the corresponding second reference holes 8a, and the state where the second connecting member 6 is attached to the pin board 3 (the state shown in FIG. 14) is shown in FIG. As described above, when the second connecting member 6 is attached to the pin board 3 with the second positioning holes 33b aligned with the corresponding second reference holes 8b, the second connecting member 6 is moved along the Y axis by the distance Ly1. It is attached to the pin board 3 in a state shifted upward in FIG. Further, as shown in FIG. 16, when the second connecting member 6 is attached to the pin board 3 with the second positioning holes 33c aligned with the corresponding second reference holes 8c, the second connecting member 6 has a distance Ly2. It is attached to the pin board 3 in a state shifted only by the upper side in FIG. As shown in FIG. 17, when the second connecting member 6 is attached to the pin board 3 with the second positioning holes 33d aligned with the corresponding second reference holes 8d, the second connecting member 6 has a distance Ly3. It is attached to the pin board 3 in a state shifted only by the upper side in FIG.

  Furthermore, in this example, as described above, the third arrangement of the plurality of second reference holes 8 is line symmetric with respect to at least one of the one axis (Y axis) and the other axis (X axis). Since it is defined to be point-symmetric with respect to the second reference point O2, the second connecting member 6 is rotated by 180 ° from the state of FIGS. 14 to 17 around the axis S2 of the second fitting portion 32. By attaching to the pin board 3, it can be attached to the pin board 3 by shifting in the direction opposite to the shift direction shown in FIGS. 15 to 17. When the second connecting member 6 is rotated by 180 ° about the axis S2 of the second fitting portion 32 and attached to the pin board 3 with the second positioning hole 33a aligned with the second reference hole 8c. As a result, the axis S2 of the second fitting portion 32 coincides with the second reference point O2, and the shift amount of the second connecting member 6 with respect to the pinboard 3 becomes zero. That is, it becomes the same as the attachment state shown in FIG. For this reason, the description about the aspect of this attachment is abbreviate | omitted.

  Specifically, as shown in FIG. 18, when the second positioning hole 33b is aligned with the second reference hole 8d and the second connecting member 6 is attached to the pin board 3, the attachment state shown in FIG. As described above, the second connecting member 6 is attached to the pin board 3 while being shifted downward along the Y axis by a distance Ly1 in the figure. In addition, as shown in FIG. 19, when the second positioning member 33 is attached to the pin board 3 with the second positioning hole 33c aligned with the second reference hole 8a, the second connecting member 6 is Y for the distance Ly2. Attached to the pin board 3 in a state shifted along the axis by the lower side in FIG. In addition, as shown in FIG. 20, when the second positioning member 33 is attached to the pin board 3 with the second positioning hole 33d aligned with the second reference hole 8b, the second connecting member 6 is Y for the distance Ly3. Attached to the pin board 3 in a state shifted along the axis by the lower side in FIG.

  Therefore, in this member connection structure 1, the attachment position of each second connection member 6 with respect to the pin board 3 is set to a unit position of the second unit length ΔLy0 along the Y direction, with the position shown in FIG. It can be changed in three steps on the negative side (lower side) of the Y axis and in three steps on the positive side (upper side) of the Y axis. That is, the attachment position of the second connecting member 6 to the pin board 3 can be changed in seven stages along the Y direction, including the case of attachment to the reference position shown in FIG.

  Next, an attachment procedure (connection procedure) of the pin board 3 to the base portion 2 in a jig-type board inspection apparatus that employs the member connection structure 1 will be described. In addition, in description of the attachment position of the pin board 3 to the base part 2, while attaching each 1st connection member 5 to the base part 2 in the state shown in FIG. 6, the 2nd connection member 6 is attached to the pin board 3. On the other hand, in the state shown in FIG. 14, in this state, the second fitting portions 32 (cylindrical bodies) in the second connecting members 6 of the pin board 3 are connected to the first fitting members 5 in the first connecting members 5 of the base portion 2. By inserting into the joint portion 22 (cylindrical body) (by fitting the concave and convex portions), the mounting position of the pin board 3 with the pin board 3 attached to the base portion 2 as shown in FIG. This will be described as a position.

  As described above, the mounting position of the first connecting member 5 to the base portion 2 can be changed in seven stages, and the mounting position of the second connecting member 6 to the pin board 3 can be changed in seven stages. Yes. Therefore, in this member connection structure 1, the mounting position of the pin board 3 with respect to the base portion 2 is 7 × 7 lattice points centered on the reference mounting position described above (the coordinate value in the Y-axis direction is ΔLy0 units, X Arbitrary one point can be selected from among 49 lattice points whose coordinate values in the axial direction change in units of ΔLx0. For this reason, first, the attachment position of the pin board 3 with respect to the base part 2 is selected.

  Next, one combination in which the pin board 3 is attached to a selected attachment position from among combinations of attachment positions of the first connection members 5 with respect to the base portion 2 and attachment positions of the second connection members 6 with respect to the pin board 3. To decide. Then, the 1st connection member 5 is attached to the attachment position to the base part 2 about each 1st connection member 5 which comprises this determined one combination. In this case, as shown in FIG. 3, the first positioning hole 23 of the first connecting member 5 serving as the mounting position and the first reference hole 7 of the base portion 2 are made to coincide with each other to constitute the first positioning hole 23. The positioning pin 41 is pushed into the pair of first holes 11 constituting the second hole 24 and the first reference hole 7. Thereby, positioning of each 1st connection member 5 to base part 2 is made. Next, the fixing bolt 42 is screwed into the female screw hole 12 of the base portion 2 from the first long hole 25 of each first connecting member 5 to fix the first connecting member 5 to the base portion 2.

  Similarly to the first connection member 5 described above, the second connection member 6 is also connected to the pinboard 3 mounting position for each second connection member 6 constituting the one combination determined above. The member 6 is attached. In this case, as shown in FIG. 4, a pair of second positioning holes 33 is formed by matching the second positioning holes 33 of the second connecting member 6 and the second reference holes 8 of the pin board 3 as the mounting positions. The positioning pin 51 is pushed into the pair of third holes 13 constituting the fourth hole 34 and the second reference hole 8. Thereby, positioning of each 2nd connection member 6 to pin board 3 is made. Next, the fixing bolt 52 is screwed into the female screw hole 14 of the pin board 3 from the second long hole 35 of each second connecting member 6, and the second connecting member 6 is fixed to the pin board 3.

  Finally, the second fitting portion 32 of each second connecting member 6 attached to the pin board 3 is inserted into the first fitting portion 22 of each first connecting member 5 attached to the base portion 2. By doing so (by fitting the projections and depressions), the pin board 3 is attached to the base portion 2 as shown in FIG. Thereby, the attachment work of the pin board 3 to the base part 2 about a board | substrate inspection apparatus is completed. Further, when changing the mounting position of the pin board 3 to the base portion 2, the fixing bolt 42 is loosened and removed from the female screw hole 12 of the base portion 2, and then the positioning pin 41 is removed to remove the positioning pin 41 from the base portion 2. Each first connecting member 5 is removed. Further, after loosening the fixing bolt 52 and removing it from the female screw hole 14 of the pin board 3, the second connecting members 6 are removed from the pin board 3 by removing the positioning pins 51. Next, the combination of the mounting position of each first connecting member 5 with respect to the base portion 2 and the mounting position of each second connecting member 6 with respect to the pin board 3 where the mounting position of the pin board 3 to the base portion 2 is a desired position. After determining one, the first connecting member 5 is fixed to the base portion 2 and the second connecting member 6 is fixed to the pin board 3 according to the above-described procedure. Finally, the pin board 3 is fixed to the base portion 2. Install. Thereby, the change work of the attachment position of the pin board 3 to the base part 2 is completed.

It is also possible to adopt a configuration in which only one of the holes 8 or both of them can be attached without rotating 180 °. In addition, although it is possible to change both the mounting position of the first connecting member 5 with respect to the base portion 2 and the mounting position of the second connecting member 6 with respect to the pin board 3, a configuration in which only one of them can be changed is adopted.
