[0004] The PCB support member can be held by the transport device via a PCB support member fixture. The width of the PCB varies depending on the type of PCB. Therefore, when the PCB support member is attached to the transport device via the PCB support member fixture, it is necessary to prepare the PCB support member fixture according to the width of the PCB.

[0005] A primary objective of the present disclosure is to secure a printed circuit board support member to a transport member via a printed circuit board support member attachment regardless of the width of a printed circuit board.

[0006] The present disclosure uses the following means to achieve the main object described above. Solution to the problem

[0007] A first circuit board support fixture according to the present disclosure is a circuit board support fixture attached to a circuit board support configured to support a circuit board when the circuit board support is held by a transport device and transported to a circuit board working machine, the circuit board support fixture comprising: a first support member attached to a first side of the circuit board support member; a second support member attached to a second side of the circuit board support member opposite the first side; a coupling portion configured to couple the first support member and the second support member such that a distance between the first support member and the second support member is adjustable; and a held portion held by the transport device.

[0008] In the first PCB support element fixture, the first support element and the second support element are coupled to each other in such a way that the widths of both the first support element and the second support element can be changed. Therefore, the PCB support element can be attached to a transport element via the PCB support element fixture regardless of the width of the printed circuit board.

[0009] A mounting device according to the present disclosure is a mounting device for a printed circuit board support member fixture, which is mounted on a printed circuit board support member configured to support a printed circuit board when the printed circuit board support member is held by a pair of holding portions facing each other of a transport device and transported to a printed circuit board working machine, wherein the printed circuit board support member fixture comprises a first support member fixed to a first side of the printed circuit board support member, a second support member fixed to a second side of the printed circuit board support member opposite to the first side, a coupling portion coupling a first end portion of the first support member and a first end portion of the second support member, and in which a first held portion,which is held by a first holding portion of the pair of holding portions in the transport device, and a second coupling element which couples a second end portion of the first support element and a second end portion of the second support element and in which a second held portion which is held by a second holding portion of the pair of holding portions in the transport device is formed, wherein the mounting device comprises: a first positioning member configured to releasably hold the first coupling member so that the first held portion is positioned at a first position at which the first held portion is held by the first holding portion; a second positioning member configured to releasably hold the second coupling member so that the second held portion is positioned in a second position at which the second held portion is held by the second holding portion; a first moving portion configured to support the first support member such that the first support member is parallel to a center line passing through the first position and the second position, and configured to move the first support member in an orthogonal direction orthogonal to the center line; and a second moving portion configured to support the second support member such that the second support member is parallel to the center line on a side opposite to the first moving portion with respect to the center line, and configured to move the second support member in the orthogonal direction orthogonal to the center line.

[0010] In the mounting device, the PCB support member fixture is mounted as follows. That is, first, a distance from the center line to the first moving portion and a distance from the center line to the second moving portion are set to widths corresponding to a width of the PCB support member in the orthogonal direction. In this state, the first and second support members are held by the mounting device. Then, the first and second held portions are held by the first and second positioning members, the first end portions of the first and second support members are coupled to each other by the first coupling member, and the second end portions of the first and second support members are coupled to each other by the second coupling member.Accordingly, a center position of the held portion and a center position of the printed circuit board support member can be aligned with each other in the orthogonal direction. Therefore, the printed circuit board support member can be held in a stable state by the transport device.

[0011] A second circuit board support member fixture according to the present disclosure is a circuit board support member fixture that is attached to a circuit board support member configured to support a circuit board when the circuit board support member is held by a pair of opposing holding portions of a transport device and transported to a circuit board working machine, the circuit board support member fixture comprising: a first support member attached to a first side of the circuit board support member; a second support member attached to a second side of the circuit board support member opposite the first side; a third support member secured between the first support member and the second support member and extending along an extension direction of the first support member and the second support member; and a pair of held portions provided at both end portions of the third support member in the extending direction and held by the pair of holding portions of the transport device.

[0012] In the second PCB support member fixing device, the first to third support members can be fixed to the PCB support member at positions corresponding to a width of a PCB member. Therefore, the PCB support member can be fixed to a transport member via the PCB support member fixing device regardless of the width of the PCB.

[0013] Hereinafter, an embodiment of the present disclosure will be described with reference to the accompanying drawings.

[0014] Fig. 1 is a schematic configuration diagram of the working device 10. Fig. 2 is a perspective view showing the internal configuration of the working device 10. Fig. 3 is a side view showing the internal configuration of the working device 10. Fig. 4 is a perspective view of the transport device 70. In the Fig. 1 to 4, a left-right direction is referred to as an X-axis, a front-back direction as a Y-axis, and a top-bottom direction as a Z-axis.

[0015] The work device 10 performs a predetermined work on the printed circuit board S supported by the printed circuit board support member 80. In the present embodiment, the work device 10 is configured as a printing device that applies (prints) a solder paste on the printed circuit board S below the pattern holes P1 and P2 as a predetermined work by pressing the solder paste on the screen mask M into the pattern holes P1 and P2 formed in the screen mask M using the squeegee 22. The work device 10 constitutes a component mounting system in combination with a mounting device that mounts an electronic component on the printed circuit board S on which solder is printed.Furthermore, the working device 10 is capable of automatically replacing the screen mask M or automatically replacing the circuit board support member 80 using the transport device 70 when a change for changing a printing target to another type of circuit board S is performed.

[0016] As in the Fig. 1 to 3, the work apparatus 10 includes a work apparatus main body 11, a replacement apparatus 50, a receiving frame 60, and a control apparatus 100. The work apparatus main body 11 includes a head apparatus 20 having a head 21, support rails 29 supporting the screen mask M and the conveying apparatus 70, and first and second printed circuit board conveying and supporting apparatuses 30 and 40 that convey and support the printed circuit board S in two lanes. In addition, the work apparatus 10 also includes an operation panel installed in front of the work apparatus main body 11, which displays various information and enables various input operations of a worker.

[0017] The head device 20 is installed in an upper stage of the working device main body 11. As shown in Fig. 1, the head device 20 includes a head 21 and a head moving device 26 that moves the head 21 in the front-to-back direction (Y-axis direction), which is a printing direction. The head moving device 26 includes a Y-axis slider 27 that moves along a guide rail 28 extending in the front-to-back direction, and a motor that drives the Y-axis slider 27. The head 21 includes a squeegee 22, a squeegee raising and lowering device for raising and lowering the squeegee 22, for example, by an air cylinder, a slider 24, and a slider raising and lowering device for raising and lowering the slider 24, for example, by an air cylinder. The squeegee 22 is a plate-shaped element that extends in the left-right direction (X-axis direction) orthogonal to the printing direction.The slider 24 is reciprocated by the head moving device 26 in a state where the slider 24 is lowered by the slider raising and lowering device 25 and protrudes downward, so that the slider 24 pushes the screen mask M and the conveying device 70 back and forth on the support rails 29 to convey the screen mask M and the conveying device 70. When the circuit board support member 80 is replaced using the transfer device 70, the slider 24 is also used to collect the circuit board support member 80 on the tables 36 and 46 to the transfer device 70, which is transferred onto the support rails 29, or to take out the circuit board support member 80 from the transfer device 70, which is transferred onto the support rails 29, in a state where the circuit board support member 80 is held, and place the circuit board support member 80 on the tables 36 and 46.

[0018] The screen mask M is a thin metal plate and is fixed to a rectangular frame body F with a predetermined tension. In the screen mask M, pattern holes P1 and P2 are formed for respectively printing solder on the circuit board S, which is transported and supported by first and second circuit board transport and support devices 30 and 40.

[0019] As in Fig. 3, the support rails 29 are a pair of left and right rails extending in the front-to-back direction (Y-axis direction) and installed between the head device 20 and the first and second circuit board conveying and supporting devices 30 and 40. The support rails 29 support the screen mask M 8 and the conveying device 70 in a horizontal position and guide the screen mask M and the conveying device 70, which are pushed by the slider 24, so that the screen mask M and the conveying device 70 move in the front-to-back direction.

[0020] The first and second circuit board transport and support devices 30 and 40 transport and support the circuit board S, bring the supported circuit board S into contact with the screen mask M on the support rails 29, and separate the supported circuit board S from the screen mask M. As shown in the Fig. 2 and Fig. As shown in FIG. 3, the first and second printed circuit board transporting and supporting devices 30 and 40 include conveyor devices 31 and 41, conveyor pitch changing devices, conveyor raising and lowering devices 35 and 45, tables 36 and 46, and support member raising and lowering devices 37 and 47. The conveyor devices 31 and 41 include conveyor belts provided on a pair of front and rear side frames 33s and 43s, respectively, and motors that drive the conveyor belts to rotate. The pair of side frames 33s and 43s are mounted on base frames 33b and 43b, and printed circuit board guides 32 and 42 are provided at the upper end portions of the pair of side frames 33s and 43s. Conveyor pitch changing devices 34 and 44 change (adjust) a pitch between the conveyor belts by moving one or both of the side frame pairs 33s and 43s closer to or away from each other.Accordingly, first and second printed circuit board transport and support devices 30 and 40 can transport and support printed circuit boards S of different sizes. The conveyor lifting and lowering devices 35 and 45 lift and lower the conveyor devices 31 and 41 (conveyor belts) by raising and lowering support columns that support the base frames 33b and 43b. The tables 36 and 46 are support tables that have an installation surface on a top surface on which printed circuit board support members 80 can be installed. The support member lifting and lowering devices 37 and 47 lift and lower the printed circuit board support members 80 installed on the tables 36 and 46 by raising and lowering the support columns that support the tables 36 and 46.

[0021] The exchange device 50 accommodates a receiving rack 60 that accommodates replacement elements such as the screen mask M and the transport device 70, and transports the replacement elements between the receiving rack 60 and the work device main body 11. The exchange device 50 includes a left unit 51a installed on a left side at a front side of the work device main body 11, and a right unit 51b installed on a right side at the front side of the work device main body 11. The left unit 51a and the right unit 51b include a rack support member 52 that accommodates the receiving rack 60 and supports a bottom of the receiving rack 60 from the left and right sides, and a rack lifting and lowering device 53 that lifts and lowers the rack support member 52.The rack lifting and lowering device 53 includes, for example, a combination of a ball screw mechanism and a motor or a linear motor. The receiving rack 60 held by the rack support member 52 is lifted and lowered together with the rack support member 52 by the rack lifting and lowering device 53. Furthermore, each of the left unit 51a and the right unit 51b includes a frame front-to-back moving device 54 that reciprocates a frame of the replacement member within the receiving rack 60 from the left and right sides by means of a belt, a pulley, or the like.

[0022] The receiving frame 60 is a receiving body that includes pairs of left and right support rails 61 arranged in multiple stages in the up-down direction, and can accommodate the replacement element in each support rail 61. Additionally, openings 62 and 62 are formed on the work device main body 11, a front side, and a rear side of the receiving frame 60. The replacement element is taken in and out by the worker or the like through the opening 62 on a front side, and transported in and out by the frame front-back moving device 54 through the opening 62 on a rear side.In a state where the receiving rack 60 is received by the replacement device 50, the frame front-to-back moving device 54 conveys the replacement member supported under the support rails 61 in the multiple stages of the receiving rack 60 on the support rails 61 positioned by the rack raising and lowering device 53 at substantially the same height as the support rails 29 of the work device main body 11, to the work device main body 11. In addition, the frame front-to-back moving device 54 conveys the replacement member supported on support rails 29 of the work device main body 11 to support rails 61 of the receiving rack 60 positioned at substantially the same height as the support rails 29.The receiving frame 60 can be transported by the worker to a receiving position of the exchange device 50 or mounted on an automated guided vehicle (AGV) and automatically transported by the automated guided vehicle to the receiving position of the exchange device 50.

Then, when the first arm member 72 and the second arm member 75 are pressed downward from above, the first arm member 72 and the second arm member 75 rotate against an elastic force of the spring, so that a second state is achieved in which the first arm member 72 and the second arm member 75 are extended downward. The first arm member 72 and the second arm member 75 hold the circuit board support member 80 in the first state and release the holding of the circuit board support member 80 in the second state. The first arm member 72 and the second arm member 75 are pressed downward by the slider 24.In the present embodiment, the transport device 70 includes two pairs of first arm members 72 and second arm members 75 that hold circuit board support members 80, and each pair can respectively transport circuit board support members 80 used in the first and second circuit board transport and support devices 30 and 40.

The pair of second pin elements 94a engages with the second engagement element 76 by fitting the second engagement element 76 therebetween.

[0032] In the circuit board support member fixture 90, in a state where the first fixing member 91 and the second fixing member 92 are close to each other in the front-rear direction, the first rail member 91b of the first fixing member 91 and the first rail member 92b of the second fixing member 92 can be coupled to each other by the first coupling member 93, and the second rail member 91c of the first fixing member 91 and the second rail member 92c of the second fixing member 92 can be coupled to each other by the second coupling member 94.Furthermore, in a state where the first fixing member 91 and the second fixing member 92 are separated from each other in the front-rear direction, the first rail member 91b of the first fixing member 91 and the first rail member 92b of the second fixing member 92 can be coupled to each other by the first coupling member 93, and the second rail member 91c of the first fixing member 91 and the second rail member 92c of the second fixing member 92 can be coupled to each other by the second coupling member 94. As described above, in the printed circuit board support member fixture 90, since the distance between the first fixing member 91 and the second fixing member 92 can be adjusted, the printed circuit board support member 80 can be fixed to the conveying device 70 via the printed circuit board support member fixture 90 regardless of a width of the printed circuit board S.

[0033] As in Fig. 6A, the width d1 of the first engagement element 74 is smaller than the width d2 of the second engagement element 76, and the distance D1 between the pair of first pin elements 93a held by the first engagement element 74 is smaller than the distance D2 between the pair of second pin elements 94a with which the second engagement element 76 is engaged. Accordingly, as shown in Fig. 6B, the printed circuit board support member 80 is held in a horizontal position when the right and left sides of the printed circuit board support member 80 are attached to the transport device 70 in the correct direction. On the other hand, as shown in the Fig. 7A and Fig. As shown in Figure 7B, when the printed circuit board support member 80 is mounted on the transfer device 70 with the left and right sides rotated 180 degrees, the second engagement member 76, which has a width d2 greater than the distance D1 between the first pin members 93a, does not normally engage the first pin members 93a, and thus the printed circuit board support member 80 is maintained in a state of being inclined with respect to the transfer device 70. Accordingly, the worker can be alerted that the printed circuit board support member 80 has been mounted in the wrong direction. The width d1 of the first engagement member 76 is smaller than the smallest width of the printed circuit board support members 80 usable in the work device 10.

[0034] The control device 100 is configured as a microprocessor, mainly including a CPU, and in addition to the CPU, a ROM, a RAM, an input / output port, and the like. The control device 100 exchanges signals with the head device 20, the first and second circuit board transporting and supporting devices 30 and 40, the exchange device 50, and the like. Furthermore, the control device 100 is communicatively connected to a management device 200, which manages an entire work system including the work device 10. The management device 200 manages a progress status and the like of a line including the work device 10.

[0035] An operation of the work apparatus 10 configured as described above will be described. In the present embodiment, a replacement process for replacing the screen mask M and the printed circuit board support member 80 will be described. The replacement is performed by executing a mask outfeed process, a support member outfeed process, a support member infeed process, and a mask infeed process in this order in a state where the receiving rack 60 is set in the replacement device 50.

[0036] The mask carrying-out process is a process of carrying out a used screen mask M from the work device main body 11 and accommodating the screen mask M in the receiving rack 60. In the mask carrying-out process, the device 100 controls the rack lifting and supporting device 53 so that the empty support rails 61 of the receiving rack 60 are substantially at the same height as the support rails 29 of the work device main body 11. Then, the control device 100 controls the head moving device 26 so that the screen mask M supported by the support rail 29 is pushed forward by the slider 24 and carried out of the work device main body 11. Then, the control device 100 controls the frame front-to-back moving device 54 so that the transported screen mask M is accommodated in the receiving rack 60.The mask-in process is a process of taking out the screen mask M to be used next from the receiving rack 60 and transporting the screen mask M into the working device main body 11. Since the mask-in process is substantially in the reverse order of the mask-out process, a description thereof will be omitted.

[0037] In the support member carrying out process, the used circuit board support member 80 is carried out from the working device main body 11 and accommodated in the receiving rack 60. First, the control device 100 controls the rack lifting and supporting device 53 so that the support rails 61 of the receiving rack 60, which support the empty conveying device 70 used for collecting the printed circuit board support member 80, are substantially at the same height as the support rails 29 of the work device main body 11. Then, the control device 100 controls the frame front-back moving device 54 so that the empty conveying device 70 is transported from the receiving rack 60 into the work device main body 11, and controls the slider lifting and lowering device and the head moving device 26 so that the transported empty conveying device 70 is moved by the slider 24 into a space above the tables 36 and 46.Next, the control device 100 controls the head moving device 26 so that the slider 24 moves into a space directly above the first arm member 72 and the second arm member 75 of the empty transport device 70. Subsequently, the control device 100 controls the slider raising and lowering device 25 so that the slider 24 is lowered. As described above, when the slider 24 is lowered, the slider 24 comes into contact with the first arm member 72 and the second arm member 75. As the slider 24 is further lowered, the pair of the first arm member 72 and the second arm member 75 is extended downward, reaching a state (second state) in which the printed circuit board support member 80 can be accommodated. Next, the control device 100 controls the support member lifting and lowering device 37 or the support member lifting and lowering device 47 so that the table 36 or the table 46 is lifted.Then, the control device 100 controls the slider raising and lowering device 25 so that the slider 24 is raised. Accordingly, the first arm member 72 and the second arm member 75 are in the first state of opposing each other, and the printed circuit board support member 80 is held by the transfer device 70 (first arm member 72 and second arm member 75). The control device 100 causes the transfer device 70, through the same control, to hold the printed circuit board support member 80, which is placed on a second one of the tables 36 and 46.

[0038] Next, the control device 100 controls the rack raising and lowering device 53 to raise the receiving rack 60 until the empty support rails 61 of the receiving rack 60 are substantially at the same height as the support rails 29 of the work device main body 11. Then, the control device 100 controls the head moving device 26 to lower the slider 24 by the slider raising and lowering device 25, and the transfer device 70 is pushed forward on the support rails 29 by the slider 24 and transported out. Subsequently, the control device 100 controls the frame front-to-back moving device 54 to transport the printed circuit board support member 80 held by the transport device 70 to the receiving rack 60.

[0039] The support member transport-in process is a process of taking out the next printed circuit board support member 80 to be used from the receiving rack 60 and transporting the printed circuit board support member 80 into the work apparatus main body 11. In the support member transport-in process, the transport device 70 holding two printed circuit board support members 80 is transported into the work apparatus main body 11, and the transport device 70 is controlled so that the transport device 70 is moved into a space above the table 36 or the table 46 by the slider 24. Subsequently, the control device 100 performs control to raise the table 36 or the table 46, and then performs control to lower the slider 24 directly over the first arm member 72 and the second arm member 75 of the transfer device 70 holding a first of the two circuit board support members 80.As a result, the pair of the first arm member 72 and the second arm member 75 are extended downward (second state), and the printed circuit board support member 80 is detached from the pair of the first arm member 72 and the second arm member 75 and placed on the table 36 or the table 46. Through the same control, the control device 100 places a second one of the printed circuit board support members 80 held by the transfer device 70 on a second one of the tables. Then, the control device 100 executes control to lower the table 36 and the table 46, and executes control to transport the empty transfer device 70, from which the two printed circuit board support members 80 are removed, out of the work device main body 11 and accommodated in the receiving rack 60.

[0040] Next, a method of attaching the circuit board support member fixture 90 to the circuit board support member 80 will be described with reference to FIG. Fig. 8 to 11D. First, details of the mounting device 110 used for mounting the printed circuit board support member fixture 90 will be described with reference to Fig. 8, Fig. 9A and Fig. 9B.

[0041] The mounting device 110 includes a first positioning element 112, a second positioning element 113, a first moving section 114, a second moving section 117, a first clamping mechanism 122, and a second clamping mechanism 123. These components are provided on the loading plate 111.

[0042] A pair of left and right elongated holes 120 extending in the front-to-rear direction (Y-axis direction) are formed on the rear sides of both end portions of the loading plate 111 in the left-right direction. A scale SC indicating a position of the first moving portion 114 on the loading plate 111 is provided outside the pair of elongated holes 120 in the left-right direction (X-axis direction). A pair of left and right elongated holes 121 extending in the front-to-rear direction are formed on the front sides of both end portions of the loading plate 111 in the left-right direction. A scale SC indicating a position of the second moving portion 117 on the loading plate 111 is provided outside the pair of elongated holes 121 in the left-right direction.A distance from the later-described center line L connecting a center of the first positioning member 112 in the front-back direction and a center of the second positioning member 113 in the front-back direction is indicated on the scale SC. Note that the distance corresponds to the width of the circuit board support member 80 to which the circuit board support member fixture 90 is attached in the front-back direction, and is, for example, half the width of the circuit board support member 80 in the front-back direction.

[0043] The first positioning member 112 is used to position the first coupling member 93 when the circuit board support member fixture 90 is mounted. The first positioning member 112 is detachably attached to a substantially center of the loading plate 111 in the front-rear direction and a left end side of the loading plate 111 with a screw or the like. As shown in Fig. As shown in FIG. 9A, a width of the first positioning member 112 in the front-to-rear direction is equal to the width (width d1) of the first engagement member 74 in the front-to-rear direction. The first positioning member 112 is fixed to the loading plate 111 in a state of being fitted between the pair of first pin members 93a of the first coupling member 93, thereby positioning the first coupling member 93.

[0044] The second positioning member 113 is used to position the second coupling member 94 when the circuit board support member fixture 90 is mounted. The second positioning member 113 is detachably attached to a substantially center of the loading plate 111 in the front-rear direction and a right end side of the loading plate 111 with a screw or the like. As shown in Fig. As shown in Fig. 9B, a width of the second positioning member 113 in the front-to-rear direction is equal to the width (width d2) of the second engagement member 76 in the front-to-rear direction. The second positioning member 113 is fixed to the loading plate 111 in a state of being fitted between the pair of second pin members 94a of the second coupling member 94, thereby positioning the second coupling member 94.

[0045] The first moving portion 114 supports the first fixing member 91 when the circuit board support member fixture 90 is mounted. The first moving portion 114 is provided on a rear side of the loading plate 111 in the front-to-rear direction (Y-axis direction). The first moving portion 114 includes a first slider 115 that is reciprocally movable along the elongated hole 120 and a first block 116 that is fixed to a top surface of the first slider 115. The first moving portion 114 supports the first fixing member 91 by causing the first fixing member 91 to abut against a front side surface of the first block 116.

[0046] The second moving portion 117 supports the second fixing member 92 when the circuit board support member fixture 90 is mounted. The second moving portion 117 is provided on a front side of the loading plate 111 in the front-rear direction (Y-axis direction). The second moving portion 117 includes a second slider 118 that is reciprocally movable along the elongated hole 121 and a second block 119 that is fixed to a top surface of the second slider 118. The second moving portion 117 supports the second fixing member 92 by causing the second fixing member 92 to abut against a rear side surface of the second block 119.

[0047] The first clamping mechanism 122 fixes the first moving portion 114 at any position within a range of motion. The first clamping mechanism 122 includes a clamping screw that penetrates the elongated hole 120 in the up-down direction, a screw receptacle provided on a bottom surface of the loading plate 111 and movable back and forth together with the first slider 115, and a clamping lever that tightens and loosens the screw with respect to the screw receptacle. In the first clamping mechanism 122, the first slider 115 can move back and forth when the clamping lever is operated to loosen the screw with respect to the screw receptacle. On the other hand, in the first clamping mechanism 122, the reciprocating movement of the first slider 115 is prevented when the clamping lever is operated to tighten the screw with respect to the screw receptacle.

[0048] The second clamping mechanism 123 fixes the second moving portion 117 at any position within the moving range. The second clamping mechanism 123 includes a clamping screw that penetrates the elongated hole 121 in the up-down direction, a screw receptacle provided on the underside of the loading plate 111 and movable back and forth together with the second slider 118, and a clamping lever that tightens and loosens the screw with respect to the screw receptacle. In the second clamping mechanism 123, the second slider 118 can move back and forth when the clamping lever is operated to loosen the screw with respect to the screw receptacle. On the other hand, in the second clamping mechanism 123, the reciprocating movement of the second slider 118 is prevented when the clamping lever is operated to tighten the screw with respect to the screw receptacle.

[0049] Next, a method of fixing the printed circuit board support member fixture 90 to the printed circuit board support member 80 will be described with reference to FIG. Fig. 10 to 11D. First, the worker prepares the assembly device 110 (S100). Next, the worker moves, as shown in Fig. 11A, the operator moves the first moving portion 114 to a position in the front-to-back direction (Y-axis direction) corresponding to the width of the printed circuit board support member 80 to which the printed circuit board support member fixture 90 is attached, while viewing the scale SC, and actuates the first clamping mechanism 122 to fix the first moving portion 114 at the position (S105). In this case, the distance from the center line L to the first moving portion 114 (first block 116) is half the width of the printed circuit board support member 80 to which the printed circuit board support member fixture 90 is attached, in the front-to-back direction. Then, the worker places the circuit board support member 80 on the loading plate 111 so that a rear side surface of the circuit board support member 80 abuts against the front side surface of the first block 116 of the first moving section 114 (S110).The worker then moves the second moving section 117 until the rear side surface of the second block 119 abuts the front side surface of the printed circuit board support member 80, and actuates the second clamping mechanism 123 to fix the second moving section 117 in position (S115). In this case, the distance from the center line L to the second moving section 117 (second block 119) is half the width of the printed circuit board support member 80 to which the printed circuit board support member fixture 90 is attached, in the front-to-back direction. The worker checks the scale SC indicating the position of the first moving section 114 and the scale SC indicating the position of the second moving section 117. If the two do not match, the worker finely adjusts the positions of the first moving section 114 and the second moving section 117 with respect to the loading plate 111.

[0050] Next, the worker places the first coupling member 93 at a left end of the circuit board support member 80 with the first pin member 93a facing upward, and places the second coupling member 94 at a right end of the circuit board support member 80 with the second pin member 94a facing upward (S120). Then, the worker fits, as shown in Fig. 11C, the first rail element 91b and the second rail element 91c of the first fastening element 91 are inserted into the long groove G11 of the first coupling element 93 and the long groove G12 of the second coupling element 94, respectively, and the first fastening element 91 is placed on the printed circuit board support element 80 such that a side surface of the first fastening element main body 91a abuts the first block 116 (S125). Then, as shown in Fig. 11C, the first rail member 92b and the second rail member 92c of the second fastening member 92 are inserted into the long groove G21 of the first coupling member 93 and the long groove G22 of the second coupling member 94, respectively, and the second fastening member 92 is placed on the circuit board support member 80 so that a side surface of the second fastening member main body 92a abuts the second block 119 (S130).

[0051] Next, the worker screws (fastens) as in Fig. 11C, the first positioning member 112 is attached to the left end side of the loading plate 111 in a state where the first positioning member 112 is arranged between two first pin members 93a (S135). Then, the worker screws (fastens) as shown in Fig. 11C, the second positioning member 113 is attached to the right end side of the loading plate 111 in a state where the second positioning member 113 is interposed between a pair of second pin members 94a (S140). Then, the worker connects the first fastening member 91 and the second fastening member 92 to each other by inserting the screw B into the elongated hole L11 and tightening the screw B in the screw hole H11, inserting the screw B into the elongated hole L21 and tightening the screw B in the screw hole H21, inserting the screw B into the elongated hole L12 and tightening the screw B in the screw hole H12, and inserting the screw B into the elongated hole L22 and tightening the screw B in the screw hole H22 (S145).Accordingly, the first fastening member 91 and the second fastening member 92 can be connected to each other in a state where the center of the pair of first pin members 93a in the front-rear direction coincides with the center of the pair of second pin members 94a in the front-rear direction.

[0052] Next, the worker removes the first positioning member 112 and the second positioning member 113 from the mounting jig 110 (S150). Then, the worker removes the printed circuit board support member fixture 90 from the mounting jig 110 (S155). Next, the worker removes the printed circuit board support member 80 from the mounting jig 110 (S160). Then, the worker mounts the printed circuit board support member fixture 90 to the printed circuit board support member 80 with a screw or the like (S165) and completes the process.

[0053] In the mounting device 110, the center of the pair of first pin members 93a in the front-to-back direction can be mounted with the circuit board support member fixture 90 of the pair of second support members 94a. Therefore, the circuit board support member 80 can be held in a stable state by the transport device 70.

[0054] Here, a correspondence relationship between main elements of the embodiment and main elements of the present disclosure described in the claims will be described. That is, the circuit board support member fixture 90 of the present embodiment corresponds to a first circuit board support member fixture of the present disclosure, the first fixing member 91 corresponds to a first support member, the second fixing member 92 corresponds to a second support member, the first coupling member 93 and the second coupling member 94 correspond to a coupling portion, and the first pin member 93a and the second pin member 94a correspond to a retained portion.The first fixing member main body 91a corresponds to a first support member main body, the first rail member 91b and the second rail member 91c correspond to a first extension portion, the second fixing member main body 92a correspond to a second support member main body, and the first rail member 92b and the second rail member 92c correspond to a second extension portion. Furthermore, a mounting jig 110 corresponds to a mounting jig for a printed circuit board support member fixing, a first positioning member 112 corresponds to a first positioning member, a second positioning member 113 corresponds to a second positioning member, a first moving portion 114 corresponds to a first moving portion, and a second moving portion 117 corresponds to a second moving portion.The loading plate 111 corresponds to a loading plate, the first clamping mechanism 122 corresponds to a first fixing portion, and the second clamping mechanism 123 corresponds to a second fixing portion.

[0055] In the printed circuit board support member fixture 90 described in detail above, the first fixing member 91 and the second fixing member 92 are coupled so that their widths can be changed. Therefore, the printed circuit board support member 80 can be fixed to the conveying device 70 via the printed circuit board support member fixture 90 regardless of the width of the printed circuit board S.

[0056] In the circuit board support member fixture 90, the first fixture member 91 includes a first fixture main body 91a and a first rail member 91b and a second rail member 91c extending in the front-to-rear direction from both left and right end portions of the first fixture main body 91a. The second fixture member 92 includes a second fixture main body 92a and a first rail member 92b and a second rail member 92c extending in the front-to-rear direction from both left and right end portions of the second fixture main body 92a. Furthermore, the circuit board support member fixture 90 includes a first coupling member 93 that couples the first rail member 91b and the first rail member 92b, and a second coupling member 94 that couples the second rail member 91c and the second rail member 92c.Accordingly, the widths of the first fastening element 91 and the second fastening element 92 can be adjusted relatively easily.

[0057] In the mounting jig 110, the distance from the center line L to the first moving portion 114 and the distance from the center line L to the second moving portion 117 are set to half the width of the circuit board support member 80 in the front-to-back direction. In this state, the first fixing member 91 and the second fixing member 92 are supported by the mounting jig 110. Then, the first pin member 93a and the second pin member 94a are held by the first positioning member 112 and the second positioning member 113, respectively, and the first rail member 91b and the first rail member 92b are coupled by the first coupling member 93, and the second rail member 91c and the second rail member 92c are coupled by the second coupling member 94.Accordingly, a center position of the first pin member 93a and the second pin member 94a and a center position of the circuit board support member 80 in the front-to-back direction can be aligned with each other. Therefore, the circuit board support member can be held in a stable state by the transport device.

[0058] The mounting device 110 also includes a first positioning element 112, a second positioning element 113, a first clamping mechanism 122 that fixes the first moving section 114 at any position within a moving range, and a second clamping mechanism 123 that fixes the second moving section 117 at any position within the moving range. Therefore, when the positions of the first fixing element 91 and the second fixing element 92 are aligned with the positions of the first moving section 114 and the second moving section 117, respectively, the positions of the first moving section 114 and the second moving section 117 are less likely to shift.

[0059] It goes without saying that the present disclosure is not limited to the embodiments described above and can be implemented in various aspects as long as these aspects fall within the technical scope of the present disclosure.

[0060] For example, in the above-described embodiment, the printed circuit board support member 80 is held by the transport device 70 using the printed circuit board support member fixture that can adjust the distance between the first fixture member 91 and the second fixture member 92 in the front-to-back direction. However, as shown in the Fig. 12A and Fig. 12B, the circuit board support member 80 can be held by the transport device 70 using the circuit board support member fixture 190. The circuit board support member fixture 190 includes a first fixture 191 extending in the left-right direction (X-axis direction) and fixed to one side on the front side of the circuit board support member 80, a second fixture 192 extending in the left-right direction and fixed to one side on the back side of the circuit board support member 80, and a third fixture 193 extending in the left-right direction and extending between the first fixture 191 and the second fixture 192.The third fixing member 193 is fixed to the circuit board support member 80 such that its center in the front-to-back direction coincides with the center of the circuit board support member 80 in the front-to-back direction. A pair of first pin members 193a, which engage with a first engagement member 74 provided on a first arm member 72 of the conveying device 70, is provided at a left end portion of the third fixing member 193. A pair of second pin members 194a, which engage with a second engagement member 76 provided on a second arm member 75 of the conveying device 70, is provided at a right end portion of the third fixing member 193. A width between first pin elements 193a in the front-rear direction is a width (width D1) equal to the width between the first pin elements 93a in the circuit board support member fixture 90.A width between the second pin elements 194a in the front-to-back direction is a width (width D2) equal to the width between the second pin elements 94a in the printed circuit board support member fixture 90. Accordingly, the printed circuit board support member 80 can be fixed to the transfer device 70 via the printed circuit board support member fixture 190 regardless of the width of the printed circuit board S.

[0061] In the embodiment described above, the width D1 between the first pin elements 93a in the front-to-rear direction is smaller than the width D2 between the second pin elements 94a in the front-to-rear direction. However, the width D1 may be larger than the width D2. Alternatively, the width D1 may be equal to the width D2.

[0062] In the above-described embodiment, in the method for attaching a printed circuit board support fixture, after the printed circuit board support fixture 90 and the printed circuit board support 80 are removed from the mounting jig 110, the printed circuit board support fixture 90 is attached to the printed circuit board support 80. However, in the method for attaching a printed circuit board support fixture, the printed circuit board support 80 may be removed from the mounting jig 110 together with the printed circuit board support fixture 90 after the printed circuit board support fixture 90 is attached to the printed circuit board support 80.

[0063] In the embodiment described above, the retained portion of the present disclosure was described as a pair of first pin members 93a and a pair of second pin members 94a. However, the retained portion of the present disclosure may have a different configuration. For example, instead of the pair of first pin members 93a, a recessed portion engaged with the first engagement member 74 may be used, or instead of the pair of second pin members 94a, a recessed portion engaged with the second engagement member 76 may be used.

[0064] Here, a method for attaching a printed circuit board support fixture according to a modification example will be described. In the method for attaching a printed circuit board support fixture according to the modification example, a direction in which the first fixing member 91 and the second fixing member 92 are placed on the printed circuit board support 80 may be reversed from that in the above-described embodiment. That is, when attaching the printed circuit board support fixture 90 to the printed circuit board support 80, the first fixing member 91 and the second fixing member 92 may be placed and mounted on the printed circuit board support 80 in a state where the surfaces of the first fixing member 91 and the second fixing member 92 that come into contact with the printed circuit board support 80 face upward.In this case, the first rail members 91b and 92b of the first and second fixing members 91 and 92 are coupled to each other by a first coupling member 93 in a state where a pair of first pin members 93a faces downward. Furthermore, the second rail members 91c and 92c of the first and second fixing members 91 and 92 are coupled to each other by a second coupling member 94 in a state where a pair of second pin members 94a faces downward.

[0065] In the method for fixing a printed circuit board support member fixture according to the modified example, the worker screws (fixes) the first positioning member 212 and the second positioning member 213 to the loading plate 111 before placing the first fixing member 91 and the second fixing member 92 on the printed circuit board support member 80. Then, the worker covers the first coupling member 93 from above the first rail member 91b of the first fixing member 91 and the first rail member 92b of the second fixing member 92, inserts the screw B into each elongated hole, and tightens the screw B in each screw hole.In this case, it is desirable that the elongated hole L11 and the elongated hole L21 be formed on one side of the first coupling member 93, the screw hole H11 on one side of the first rail member 91b of the first fastening member 91, and the screw hole H21 on one side of the first rail member 92b of the second fastening member 92. The worker covers the second coupling member 94 from above the second rail member 91c of the first fastening member 91 and the second rail member 92c of the second fastening member 92, inserts the screw B into each elongated hole, and tightens the screw B in each screw hole.In this case, it is desirable that the elongated hole L12 and the elongated hole L22 be formed on one side of the second coupling member 94, the screw hole H12 be formed on one side of the second rail member 92c of the first fixing member 91, and the screw hole H22 be formed on one side of the second rail member 92c of the second fixing member 92. This is because, as in the above-described embodiment, when screw holes are formed in the first coupling member 93 and the second coupling member 94 and elongated holes are formed in the first rail members 91b and 92b and the second rail members 91c and 92c, it is necessary to tighten the screws B from a rear side, and it is difficult to couple the first fixing member 91 and the second fixing member 92.The method for fixing a printed circuit board support fixture according to the modified example is used for mounting a printed circuit board support fixture 90 fixed to a printed circuit board support 80 having a relatively short length in the front-to-back direction. This is because, when the width of the printed circuit board support 80 in the front-to-back direction is short, when the printed circuit board support fixture 90 is mounted in the same method as in the above-described embodiment, the first fixing member 91 and the second fixing member 92 cannot be coupled in some cases. As shown in FIGS. Fig. 14A and Fig. 14B, a case is considered where the first fixing member 91 and the second fixing member 92 are brought close to each other so that the fixed portions 91d and 92d abut each other and the fixed portions 91f and 92f abut each other, since the circuit board support member fixing member 90 is fixed to the circuit board support member 80 having a short width in the front-rear direction. In this case, when the surface that comes into contact with the circuit board support member 80 when the circuit board support member fixture 90 is fixed to the circuit board support member 80 faces downward, the first rail member 91b and the second rail member 91c are hidden under the fixed portions 92d and 92f, respectively, and the first rail member 92b and the second rail member 92c are hidden under the fixed portions 91d and 91f, respectively.Therefore, screw B cannot be tightened by the same method as in the embodiment described above.

[0066] The details of the procedure will be explained in the Fig. 13 and Fig. 14. In Fig. 13 are the same processes as in Fig. 10 are labeled with the same step numbers, and a detailed description is omitted.

[0067] First, similar to the above-described embodiment, the worker prepares the mounting device 110, fixes the first moving section 114 at a position corresponding to the width of the circuit board support member 80, and places the circuit board support member 80 on the loading plate 111 (S100 to S110). Next, the worker moves the second moving section 117 until the second block 119 abuts against a side surface of the circuit board support member 80, and fixes the second moving section 117 (S110, S115). Then, the worker screws (fixes) as shown in Fig.14A, the first positioning member 212 is attached to the right end side of the loading plate 111 (S200). Then, the worker screws (fastens) the second positioning member 213 to the left end side of the loading plate 111 (S205). Here, the lengths of the first positioning member 212 and the second positioning member 213 in the up-down direction are shorter than the lengths of the first positioning member 112 and the second positioning member 113 in the up-down direction. Next, the worker places the first fastening member 91 on the circuit board support member 80 with the surface that comes into contact with the circuit board support member 80 when attached to the circuit board support member 80 facing upward and the side surface abutting the first block 116 (S210).Next, the worker places the second fixing member 92 onto the circuit board support member 80 with the surface that contacts the circuit board support member 80 when fixed to the circuit board support member 80 facing upward and the side surface abutting the second block 119 (S215). Then, with the pair of first pin members 93a facing downward, the worker inserts the first rail member 91b of the first fixing member 91 and the first rail member 92b of the second fixing member 92 into the long grooves G11 and G21, respectively, and places the first coupling member 93 so that the first positioning member 212 is sandwiched by the first pin members 93a (S220). Then, with the two second pin elements 94a pointing downward, the worker places the second rail element 91c of the first fastening element 91 and the second rail element 92c of the second fastening element 92 into the long grooves G12 and G13, respectively.G22 and places the second coupling member 94 so that the second positioning member 213 is sandwiched by the second pin members 94a (S225). Then, the worker couples the first fastening member 91 and the second fastening member 92 together by inserting the screw B into each slot and tightening the screw B in each slot (S145). Next, the worker removes the printed circuit board support member fixture 90, the first positioning member 212, the second positioning member 213, and the printed circuit board support member 80 in this order from the mounting jig 110 (S155, S150, S160). Then, the worker mounts the printed circuit board support member fixture 90 to the printed circuit board support member 80 with a screw or the like (S165) and completes the process.

[0068] Furthermore, in the embodiment described above, the working device 10 comprises two tracks that transport and carry the printed circuit board S, but it may also comprise only one track.
