Description

[Technical Field]

[0001] This specification discloses a work device. [Background technology]

[0002] Conventionally, a working device capable of automatically replacing a substrate support member that supports a substrate has been known. For example, Patent Document 1 discloses a printing device that loads a transport jig with a substrate support member already attached thereto, removes the substrate support member from the loaded transport jig and places it on a support table, and then loads the transport jig after removing the substrate support member. The transport jig has a frame, multiple arms extending inward from the frame, and recessed protrusion holders (first to fourth protrusion holders) disposed on the top surfaces of the distal ends of each arm. The protrusion holders are disposed in pairs in the left-right direction. The substrate support member is provided with a pair of cylindrical protrusions disposed to protrude from the left and right sides of the main body. The pair of protrusions is held by the corresponding protrusion holders of the transport jig. Furthermore, the second and fourth protrusion holders, which form a pair on the left and right sides of the transport jig, are adjustable in the front-rear direction so that multiple types of substrate support members of different sizes can be attached. The operator adjusts the positions of the second and fourth protrusion holding portions according to the substrate support member to be used, attaches the substrate support member to the transport jig, and stores the transport jig in the storage unit and sets it in the printing apparatus main body. When storing the transport jig in the storage unit, the operator may use a barcode reader to read the barcodes affixed to the substrate support member and the transport jig to verify that the correct members are stored in the storage unit. The printing apparatus main body removes the transport jig with the attached substrate support member from the storage unit and transports (carries) it forward so that the substrate support member is positioned above the support base. The printing apparatus main body then raises the support base to lift the multiple protrusions on the substrate support member from the respective protrusion holding portions of the transport jig. The printing apparatus main body then moves the transport jig backward and then lowers the support base, transporting (carrying) the transport jig backward and fixing the substrate support member on the support base.

[0003] [Patent Document 1] International Publication No. 2016 / 199207 Summary of the Invention [Problem to be solved by the invention]

[0004] Patent Document 1 describes a method in which an operator performs verification by reading barcodes attached to the substrate support member and the transport jig using a barcode reader. However, verification by an operator is a heavy burden, and there is also a risk that the operator may forget to perform the verification process. For this reason, it is desirable to automatically determine whether the support member is appropriate using a simple configuration.

[0005] A main object of the present disclosure is to automatically determine whether a support member that supports a substrate is appropriate using a simple configuration in an automatically replaceable support member. [Means for solving the problem]

[0006] The present disclosure has adopted the following means to achieve the above-mentioned main object.

[0007] A first working device of the present disclosure is a working device that performs work on a substrate on a support member placed on a table, and includes a control device that controls the loading of a transport jig holding the support member and automatic replacement of the support member, and a reading device that reads a read portion provided on the support member, and the transport jig includes a first arm member that supports a first side portion on an outer edge portion of a bottom surface of the support member, and a second arm member that is disposed so that the tip ends of the first arm member and the second arm member face each other and face the first side portion on the outer edge portion of the bottom surface. and a second arm member supporting the edge portion, wherein the support member includes, as the readable portion, a first readable portion provided on a third edge portion adjacent to the first edge portion on the outer edge of the bottom surface, and a second readable portion provided on a fourth edge portion opposite the third edge portion on the outer edge of the bottom surface, and the control device, after the conveying jig holding the support member is carried in, reads the first readable portion and the second readable portion of the support member with the reading device to determine the size of the support member.

[0008] The control device of the first working device disclosed herein reads the first and second readable portions of the support member held by the transport jig after the transport jig is loaded, and determines the size of the support member relative to the transport jig. The first readable portion is provided on a third edge of the bottom outer edge of the support member, adjacent to the first edge supported by the first arm, and the second readable portion is provided on a fourth edge of the bottom outer edge of the support member, facing the third edge. Therefore, by reading the first and second readable portions of the support member, the distance between the third and fourth edges, i.e., the size of the support member, can be determined. As a result, in a device in which the support member that supports a substrate is automatically replaceable, it is possible to determine whether the support member is appropriate with a simple configuration.

[0009] A second working device of the present disclosure is a working device comprising: a working device main body that performs work on a substrate on a support member placed on a table; a storage section that can store a plurality of transport jigs, each capable of holding the support members, vertically; and a storage section lifting device that raises and lowers the storage section. The working device also comprises a memory section that associates information identifying the transport jigs stored in the storage section with information identifying the support members held on the transport jigs and stores this information in advance as support member information. A readable section on which information identifying the transport jig is written is provided on the side of the transport jig. The working device main body comprises a reading section that reads the readable section and is capable of transporting a transport jig that is stored in the storage section and is at a predetermined lift position. When the storage section is raised and lowered and the readable section passes the reading section, the reading section reads the readable section, and a determination is made as to whether the support member held on the transport jig is appropriate based on the read information and the support member information stored in the memory section.

[0010] A second working device of the present disclosure includes a working device main body, a storage unit, a storage unit lifting device, and a memory unit. The memory unit pre-stores information identifying a transport jig housed in the storage unit and information identifying a support member held by the transport jig, in association with each other, as support member information. The working device main body is capable of loading a transport jig housed in the storage unit that is at a predetermined lift position. The working device main body further includes a reading unit. When the storage unit is lifted and lowered by the storage unit lifting device and the readable portion provided on the side of the transport jig passes by the reading unit, the reading unit reads the readable portion and determines whether the support member held by the transport jig is appropriate based on the read information and the support member information stored in the memory unit. This allows a device capable of automatically replacing support members for supporting substrates to determine, with a simple configuration, whether the support member is appropriate before loading a transport jig holding the support member.

[0012] Next, embodiments of the present disclosure will be described with reference to the drawings.

[0013] Fig. 1 is a schematic diagram of a working apparatus 10 of the present disclosure. Fig. 2 is a perspective view showing the internal configuration of the working apparatus 10. Fig. 3 is a side view showing the internal configuration of the working apparatus 10. Fig. 4 is a block diagram showing the electrical connection relationship of the working apparatus. In Figs. 1 to 3, the left-right direction is the X-axis, the front-rear direction is the Y-axis, and the up-down direction is the Z-axis.

[0014] The working device 10 performs a predetermined operation on a substrate S supported by a substrate support member 90. In this embodiment, the working device 10 is configured as a printing device that, as the predetermined operation, uses a squeegee 22 to push solder paste on a screen mask M into pattern holes P1, P2 formed in the screen mask M, thereby applying (printing) the solder paste onto the substrate S below through the pattern holes P1, P2. The working device 10 constitutes a component mounting system in combination with a mounting device that mounts electronic components on the substrate S on which solder has been printed. Furthermore, the working device 10 is capable of automatically replacing the screen mask M or automatically replacing the substrate S using a transport jig 80 of the substrate support member 90 when performing a setup change to change the printing target to a different type of substrate S.

[0015] 1 to 4, the operating device 10 comprises an operating device main body 11, an exchange device 60, a storage rack 70, and a control device 100. The operating device main body 11 has a head device 20 including a head 21, support rails 29 that support the screen mask M and the transport jig 80, first and second substrate transport support devices 30, 40 that transport and support the substrate S by dual lanes, a camera device 50, and a reader 65. The operating device 10 also comprises an operation panel that is installed in front of the operating device main body 11 and that displays various information and allows the worker to perform various input operations.

[0016] The head device 20 is installed on the upper level 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-rear direction (Y-axis direction), which is the 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-rear direction, and a motor that drives the Y-axis slider 27. The head 21 includes a squeegee 22, a squeegee lifting device 23 that raises and lowers the squeegee 22 using, for example, an air cylinder, a pusher 24, and a pusher lifting device 25 that raises and lowers the pusher 24 using, for example, an air cylinder. The squeegee 22 is a plate-shaped member that extends in the left-to-right direction (X-axis direction) perpendicular to the printing direction. The pusher 24 is lowered by the pusher lifting device 25 and moved back and forth by the head moving device 26 while protruding downward, thereby pushing back and forth to transport the screen mask M and the transport jig 80 on the support rails 29. The pusher 24 is also used to retrieve the substrate support member 90 on the tables 36, 46 to the transport jig 80 that has been carried onto the support rails 29 when replacing the substrate support member 90 using the transport jig 80, or to remove the substrate support member 90 from the transport jig 80 that has been carried onto the support rails 29 while holding the substrate support member 90, and place it on the tables 36, 46.

[0017] The screen mask M is a thin metal plate, and is fixed with a predetermined tension to a rectangular frame F. The screen mask M has pattern holes P1 and P2 formed therein for printing solder onto the substrates S transported and supported by the first and second substrate transport and support devices 30 and 40, respectively.

[0018] 3, the support rails 29 are a pair of left and right rails extending in the front-to-rear direction (Y-axis direction), and are installed between the head device 20 and the first and second substrate transport support devices 30, 40. The support rails 29 support the screen mask M and the transport jig 80 in a horizontal position, and also guide the screen mask M and the transport jig 80 pushed by the pusher 24 so that they move in the front-to-rear direction.

[0019] The first and second substrate transport and support devices 30, 40 transport and support the substrate S, and also move the supported substrate S into and out of contact with the screen mask M on the support rails 29. As shown in FIGS. 2 to 4, the first and second substrate transport and support devices 30, 40 each include a conveyor device 31, 41, a conveyor spacing change device 34, 44, a conveyor lifting device 35, 45, tables 36, 46, and a support member lifting device 37, 47. The conveyor device 31, 41 includes a conveyor belt provided on a pair of front and rear side frames 33s, 43s, respectively, and a motor for driving the conveyor belt. The pair of side frames 33s, 43s are erected on base frames 33b, 43b, and substrate guides 32, 42 are provided at the upper ends of the pair of side frames 33s, 43s. The conveyor spacing change device 34, 44 changes (adjusts) the spacing of the conveyor belt by moving one or both of the pair of side frames 33s, 43s closer to or farther apart. This allows the first and second board transport and support devices 30, 40 to transport and support boards S of different sizes. The conveyor lifting device 35, 45 raises and lowers the conveyor device 31, 41 (conveyor belt) by raising and lowering the support columns that support the base frames 33b, 43b. The tables 36, 46 are support platforms with an installation surface on the upper surface on which the board support member 90 can be installed. The support member lifting device 37, 47 raises and lowers the board support member 90 installed on the tables 36, 46 by raising and lowering the support columns that support the tables 36, 46.

[0020] The board support member 90 supports the board S from the underside and is replaced with a member of a size appropriate for supporting the board S, as shown in FIGS. 5A, 5B, 6A, and 6B. The board support member 90 includes a support member main body 91 and an adapter 92 that is detachably attached to the bottom surface of the support member main body 91. A recess 91a is formed on the top surface of the support member main body 91. The recess 91a is provided, for example, when producing a board S with components mounted on both sides, so that after solder paste is printed on one side of the board S to mount the components, the other side of the board S does not interfere with the mounted components. Therefore, the support member main body 91 is dedicated to producing that board S, but the adapter 92 is detachable from the support member main body 91. Therefore, when changing the board S to be produced, it is sufficient to replace only the support member main body 91 as long as the size is appropriate, and the adapter 92 can be used as is. Furthermore, an identification mark 91b for identifying the support member main body 91 is provided on the upper surface of the support member main body 91. In this embodiment, the identification mark 91b is an ID code bearing unique information for identifying the support member main body 91.

[0021] A pair of first pin members 94a (first engaged portions) are provided on a first side portion 92a on the outer edge of the bottom surface of the adapter 92. The first pin members 94a (first engaged portions) are engaged with the first arm member 82a, which is one of the pair of arm members 82 of the transport jig 80 that holds the substrate support member 90. The second side portion 92b, which faces the first side portion 92a on the outer edge of the bottom surface of the adapter 92, is provided with a pair of second pin members 94b (second engaged portions). The second pin members 94b are engaged with the second arm member 82b, which is the other of the pair of arm members 82.

[0022] Furthermore, two first recognition marks 93c are formed on a third side 92c adjacent to (orthogonal to) the first side 92a at the outer edge of the bottom surface of the adapter 92. Furthermore, two second recognition marks 93d are formed on a fourth side 92d facing the third side 92c at the outer edge of the bottom surface of the adapter 92. The first and second recognition marks 93c, 93d are used by the working device main body 11 to recognize the position and size (front-rear width) of the board support member 90 when replacing the board support member 90.

[0023] 1 and 2, the camera device 50 includes a camera body 51 and a camera moving device 55 that moves the camera body 51 back and forth and left and right (X and Y directions). The camera moving device 55 includes an X-axis slider 56, a motor that drives the X-axis slider 56, a Y-axis slider 58, and a motor that drives the Y-axis slider 58. The Y-axis slider 58 is an elongated member that extends left and right and is bridged between a pair of left and right Y-axis guide rails 59, and moves back and forth along the Y-axis guide rails 59. The X-axis slider 56 moves left and right along an X-axis guide rail 57 provided on the Y-axis slider 58. The camera body 51 is fixed to the X-axis slider 56 and has two imaging fields of view (upper reading unit 52 and lower reading unit 53) on the top and bottom. The camera device 50 acquires the position of the substrate S by capturing an image of a mark formed on the upper surface of the substrate S carried in and supported by the first and second substrate transport and support devices 30, 40 using the lower reading unit 53. The camera device 50 also acquires an image of a mark (first and second recognition marks 93c, 93d) formed on the bottom surface of the substrate support member 90 (adapter 92) carried in on the support rails 29 together with the transport jig 80 using the upper reading unit 52, thereby acquiring the position and size (front-to-rear width) of the substrate support member 90. The camera device 50 also acquires an image of a mark (recognition mark 91b) formed on the upper surface of the substrate support member 90 (support member main body 91) placed on the tables 36, 46 using the lower reading unit 53, thereby acquiring identification information of the support member main body 91.

[0024] The exchange device 60 receives a storage rack 70 that stores replacement parts such as screen masks M and transport jigs 80, and transports the replacement parts between the storage rack 70 and the operating device main body 11. The exchange device 60 includes a left unit 61a installed on the left side of the front of the operating device main body 11, and a right unit 61b installed on the right side of the front of the operating device main body 11. The left unit 61a and the right unit 61b each include a rack support member 62 that receives the storage rack 70 and supports its underside from both the left and right sides, and a rack lifting device 63 that raises and lowers the rack support member 62. The rack lifting device 63 is configured, for example, by a combination of a ball screw mechanism and a motor, or a linear motor. The storage rack 70 supported by the rack support member 62 is raised and lowered together with the rack support member 62 by the rack lifting device 63. Furthermore, the left unit 61a and the right unit 61b have a frame forward / backward moving device 64 that feeds the frames of the replacement parts in the storage rack 70 forward and backward from both the left and right sides by means of belts, rollers, or the like.

[0025] The storage rack 70 is a storage body that has a pair of left and right support rails 71 in multiple tiers, one above the other, and is capable of storing a replacement part on each support rail 71. Openings 72, 73 are formed on the front and rear sides of the storage rack 70, facing the working device main body 11. A worker or the like inserts or removes a replacement part through the opening 72 on the front side, and the frame front-rear movement device 64 carries the replacement part in and out through the opening 73 on the rear side. When the storage rack 70 is received in the exchange device 60, the frame front-rear movement device 64 uses the rack lifting device 63 to send a replacement part supported on one of the support rails 71 of the storage rack 70 that is positioned at approximately the same height as the support rails 29 of the working device main body 11 to the working device main body 11. The frame front-rear movement device 64 also sends the replacement part supported on the support rails 29 of the working device main body 11 into the support rails 71 of the storage rack 70 that are positioned at approximately the same height as the support rails 29. The storage rack 70 may be transported to the receiving position of the exchange device 60 by an operator, or may be mounted on an automated guided vehicle (AGV) and automatically transported to the receiving position of the exchange device 60 by the automatic guided vehicle.

[0026] The reader 65 detects the storage orientation of the transport jig 80 stored in the storage rack 70 and acquires identification information of the transport jig 80. As shown in FIG. 7 , the reader 65 is provided on the front of the working device main body 11 so as to face the side of the transport jig 80 (frame body 81) stored in the storage rack 70 when the exchange device 60 has received the storage rack 70. One side of the transport jig 80 is provided with an identification mark 83 for identifying the transport jig 80. In this embodiment, the identification mark 83 is an ID code bearing unique information for identifying the transport jig 80. The storage orientation and identification information of the transport jig 80 are acquired by the reader 65 reading the identification mark 83 when the storage rack 70 storing the transport jig 80 is raised or lowered by the rack lifting device 63 and the side of the transport jig 80 passes in front of the reader 65. The storage orientation of the transport jig 80 is determined to be correct if the reader 65 can recognize the recognition mark 83, and is determined to be incorrect if the reader 65 cannot recognize the recognition mark 83 of the transport jig 80.

[0027] 8 and 9, the transport jig 80 is a jig used to load and unload the substrate support member 90, and includes a rectangular frame body 81 and a pair of arm members 82 (a first arm member 82a and a second arm member 82b) that are fixed to the frame body 81 with their tip ends facing each other and that hold the substrate support member 90 from both sides. In this embodiment, the transport jig 80 has two pairs of arm members 82 that hold the substrate support member 90, and is able to transport the substrate support members 90 used in the first and second substrate transport and support devices 30, 40 at the same time.

[0028] As shown in FIG. 10, each arm member 82 (first arm member 82a, second arm member 82b) has a base member 821, an arm plate 822, a holding member 823, a side plate 825, a lock plate 826, and a lock block 827. To facilitate understanding of the configuration, the side plate 825 and lock plate 826 on the near side are shown by dashed lines in FIG. 10. The base member 821 is fixed to the frame 81. The base end of the arm plate 822 is rotatably supported by the base member 821, and a holding member 823 is rotatably attached to the tip end of the arm plate 822. The side plates 825 are provided on both sides of the arm plate 822. The base end of the side plate 825 is rotatably supported by the base member 821, and a holding member 823 is rotatably attached to the tip end of the side plate 825. Furthermore, the side plate 825 receives the biasing force of a torsion coil spring 824 provided on the rotation shaft on the base member 821 side and biases the arm plate 822 upward. The side plate 825 is placed in a substantially horizontal position by a stopper formed on the base member 821, and holds the arm plate 822 in a substantially horizontal position. The holding member 823 constitutes the tip of the arm member 82 and engages with a pair of first pin members 94a provided on a first side portion 92a or a pair of second pin members 94b provided on a second side portion 92b at the outer edge of the bottom surface of the substrate support member 90 to hold the substrate support member 90. As a result, the substrate support member 90 is held from both sides by the tips (holding members 823) of the pair of arm members 82. The substrate support member 90 held by the pair of arm members 82 is detached from the transport jig 80 and placed on the tables 36, 46 by pressing down and spreading out each arm plate 822 of the pair of arm members 82 above the tables 36, 46.

[0029] The lock plate 826 locks the arm plate 822 so that it cannot be pressed down. The lock plates 826 are arranged on both sides of the arm plate 822, and a lock block 827 is fixed between the two lock plates 826 so as to be located below the arm plate 822. The base end of the lock plate 826 is rotatably attached to the base member 821 at a position eccentric to the rotation axis on the base end side of the arm plate 822, and the lock plate 826 is pulled toward the arm plate 822 by the biasing force of a tension spring 828 engaged with the lock plate 826 and the arm plate 822 at the tip end side of the base end. The lock block 827 engages with a notch 822c formed on the underside of the arm plate 822, thereby locking the arm plate 822 so that it cannot be pressed down. Furthermore, the tip ends of both lock plates 826 protrude above the arm plate 822 when the lock blocks 827 are engaged with the notches 822c of the arm plate 822.

[0030] In the arm member 82 configured in this manner, the arm plate 822 is locked so that it cannot be pressed down, as the lock block 827 engages with the notch 822c of the arm plate 822 due to the biasing force of the tension spring 828. Therefore, even if an unintended force acts on the substrate support member 90 or the arm plate 822, the arm member 82 (arm plate 822) will not be pressed down, preventing detachment of the substrate support member 90. The lock of the lock plate 826 can be released by pressing down the tip of the lock plate 826, which protrudes above the arm plate 822.

[0031] The unlocking of the lock plate 826 and the pressing down of the arm plate 822 are performed by a single pusher 24. As shown in FIGS. 11 and 12, the pusher 24 has a pair of front and rear pusher plates 241 arranged on the left and right at a distance corresponding to the distance between the pair of arm members 82, and a pusher roller 242 arranged between each pair of front and rear pusher plates 241. When the pusher 24 is lowered above the pair of arm members 82 by the pusher lifting device 25, the lower ends of the pair of pusher plates 241 come into contact with the tip of the lock plate 826, and the tip of the lock plate 826 is pressed down by the pusher plate 241 (see FIG. 13). When the tip of the lock plate 826 is pressed down, the lock block 827 descends, and the engagement between the lock block 827 and the notch 822c of the arm plate 822 is released (see FIG. 14). This releases the lock on the arm plate 822. As the pusher 24 moves further downward, the pusher roller 242 comes into contact with the arm plate 822, and the arm plate 822 is pressed down by the pusher roller 242 (see FIG. 15). As a result, the pair of arm members 82 are pushed apart, and the substrate support member 90 held by the pair of arm members 82 is detached from the arm members 82.

[0032] The control device 100 is configured as a microprocessor centered around a CPU, and in addition to the CPU, is equipped with ROM, RAM, a storage device 101, input / output ports, etc. The control device 100 exchanges signals with the head device 20, first and second substrate transport and support devices 30, 40, camera device 50, exchange device 60, reader 65, etc. The control device 100 is also communicably connected to a management device 200 that manages the entire work system including the work device 10. The management device 200 manages the progress status of the line including the work device 10, etc.

[0033] The operation of the working device 10 configured in this manner will be described below. In particular, the operation of the changeover for replacing the screen mask M and the substrate support member 90 will be described. The changeover is performed by setting the storage rack 70 in the exchange device 60 and executing a mask carry-out process, a support member carry-out process, a support member carry-in process, and a mask carry-in process in this order.

[0034] The mask unloading process is a process of unloading the screen mask M supported on the support rails 29 of the working device body 11 and storing it in the storage rack 70. In this mask unloading process, the control device 100 controls the rack lifting device 63 so that the empty support rails 71 of the storage rack 70 are at approximately the same height as the support rails 29 of the working device body 11. Next, the control device 100 controls the head moving device 26 so that the screen mask M supported on the support rails 29 is pushed forward by the pusher 24 and unloaded from the working device body 11. Then, the control device 100 controls the frame front-rear moving device 64 so that the unloaded screen mask M is stored in the storage rack 70. Note that the mask loading process is basically performed by the reverse operations of the mask unloading process, and therefore a description thereof will be omitted.

[0035] The support member carry-out process is a process of using the transport jig 80 to carry out the substrate support members 90 from the tables 36, 46 of the operating device main body 11 and store them in the storage rack 70, and the support member carry-in process is a process of using the transport jig 80 to carry in the substrate support members 90 from the storage rack 70 and place them on the tables 36, 46 of the operating device main body 11. Figures 16 and 17 are flowcharts showing an example of the support member carry-in process executed by the control device 100. Note that the support member carry-out process is basically executed by the reverse operations of the support member carry-in process, and therefore a description thereof will be omitted.

[0036] In the support member loading process, the control device 100 first controls the rack lifting device 63 to raise the storage rack 70 until the support rails 71 supporting the transport jig 80 to be loaded are at substantially the same height as the support rails 29 of the working device main body 11 (step S100). Next, the control device 100 performs a reading operation in which the reader 65 reads the recognition mark 83 provided on the side of the transport jig 80 (frame body 81) as the side of the transport jig 80 passes through the reader 65 (step S110), and determines whether the reading was successful or not (step S120). If the control device 100 determines that the reading was unsuccessful, it determines that the orientation of the transport jig 80 relative to the storage rack 70 may be incorrect, and outputs an error to the operation panel without loading the transport jig 80 (step S290), thereby ending the support member loading process.

[0037] On the other hand, if the control device 100 determines that the reading was successful, it performs a verification process to verify the read information (step S130) and determines whether the verification was successful (step S140). The verification process is a process for determining whether the substrate support member 90 held by the transport jig 80 that is about to be loaded is correct. Specifically, the verification process is performed by recognizing the substrate support member 90 held by the transport jig 80 from the support member information stored in the storage device 101 based on the identification information of the transport jig 80 acquired in step S110, and determining whether the recognized substrate support member 90 matches the substrate support member 90 that has been requested to be replaced during a changeover. The support member information is stored in the storage device 101 in such a manner that the identification information of the transport jig 80 and the identification information of the substrate support member 90 are associated with each other, as shown in FIG. 18 . The support member information can be stored in advance in the memory device 101, for example, by reading the recognition mark 83 on the transport jig 80 and the recognition mark 91b on the substrate support member 90 using a reader when an operator sets the substrate support member 90 on the transport jig 80.

[0038] If the control device 100 determines that the matching has failed ("NO" in step S140), it determines that the transport jig 80 that is about to be loaded is holding an incorrect substrate support member 90, and outputs an error to the operation panel (step S290) without loading the transport jig 80, thereby terminating the support member loading process.

[0039] On the other hand, if the control device 100 determines that the matching is successful ("YES" in step S140), it then controls the two substrate support members 90 held by the transport jig 80 to be transported above the tables 36, 46 of the first and second substrate transport and support devices 30, 40 (step S150). That is, the control device 100 controls the frame front-rear moving device 64 to send the transport jig 80 from the storage rack 70 to the support rails 29. Then, the control device 100 controls the pusher lifting device 25 to lower the pusher 24, and controls the head moving device 26 to use the pusher 24 to push the transport jig 80 on the support rails 29 backward and load it in.

[0040] Next, the control device 100 controls the camera device 50 so that the upper reader 52 of the camera body 51 reads the first and second recognition marks 93c and 93d provided on the bottom surface of the substrate support member 90 held by the transport jig 80 at predetermined positions (step S160). The control device 100 then recognizes the front-to-rear width (size) of the substrate support member 90 based on the positions of the read first and second recognition marks 93c and 93d (step S170) and determines whether the recognized size is appropriate (step S180). This determination can be made based on size information for the next substrate S to be produced. If the control device 100 determines that the size of the substrate support member 90 held by the transport jig 80 is inappropriate, it unloads the transport jig 80 into the storage rack 70 (step S190). That is, the control device 100 controls the head moving device 26 so that the pusher 24 pushes the transport jig 80 on the support rail 29 forward and carries it out, and also controls the frame front-back moving device 64 so that the transport jig 80 is transferred from the support rail 29 to the storage rack 70. Then, the control device 100 outputs an error to the operation panel (step S290) and ends the support member carry-in process.

[0041] On the other hand, if the control device 100 determines that the size of the substrate support member 90 held by the loaded transport jig 80 is appropriate, it controls the support member lifting device 37 or 47 to raise the table 36 or 46 to the printing height (step S200). Next, the control device 100 controls the pusher lifting device 25 to lower the pusher 24 directly above the raised table (step S210) and waits for a predetermined time to elapse (step S220). Here, the predetermined time is the waiting time until the substrate support member 90 is detached from the transport jig 80 and placed on the table 36 or 46. As described above, when the pusher 24 lowers, first, the pair of left and right pusher plates 241 abut against and press down the lock plates 826 of the pair of arm members 82, thereby unlocking the arm plates 822. Then, as the pusher 24 further descends, the pair of left and right pusher rollers 242 come into contact with and press down on the corresponding arm plates 822, spreading the pair of arm members 82. As a result, the substrate support member 90 is detached from the pair of arm members 82 and placed on the table. In this way, by simply controlling the pusher 24 to descend from directly above the pair of arm members 82, the substrate support member 90 can be detached from the transport jig 80 and placed on the table.

[0042] When the control device 100 places the substrate support member 90 on the table 36 or 46, it controls the support member lifting device 37 or 47 so that the table 36 or 46 descends to its initial position (step S230). The control device 100 similarly controls the other substrate support member 90 held by the transport jig 80 to be placed on the other table. As described above, the spacing between the pair of front and rear conveyor belts of the conveyor devices 31 and 41 is changed (adjusted) by the conveyor spacing changing devices 34 and 44 based on size information about the substrate S to be transported. Therefore, if a substrate support member 90 that is larger than the size information about the substrate S to be transported is loaded, the substrate support member 90 may interfere with the conveyor devices 31 and 41 when placed on the table 36 or 46, potentially resulting in damage to the substrate support member 90 or the conveyor devices 31 and 41. In this embodiment, the control device 100 confirms that the front-to-rear width (size) of the brought-in board support member 90 is appropriate before placing the board support member 90 on the tables 36, 46, thereby preventing the board support member 90 from interfering with the conveyor devices 31, 41.

[0043] Next, the control device 100 controls the camera device 50 so that the lower reading unit 53 of the camera body 51 reads the identification mark 91b provided on the upper surface of the substrate support member 90 (support member body 91) placed on the table 36, 46 (step S240). The control device 100 then performs a verification process to verify the identification information of the support member body 91 obtained by reading the identification mark 91b (step S250) and determines whether the verification is successful (step S260). The verification process is performed by determining whether the support member body 91 identified by the obtained identification information matches the support member body 91 requested to be replaced during the changeover. If the control device 100 determines that the verification is unsuccessful, it retrieves the substrate support member 90 placed on the table 36, 46 to the transport jig 80 on the support rail 29 (step S270). This process is performed in the same manner as the support member removal process. That is, the control device 100 lowers the pusher 24 directly above the table on which the corresponding substrate support member 90 is placed, pushes apart the pair of arm members 82, raises the table to the printing height, and raises the pusher 24 to hold the substrate support member 90 on the pair of arm members 82.

[0044] On the other hand, if the control device 100 determines that the matching is successful, it carries out the transport jig 80 that has removed the substrate support member 90 to the storage rack 70 (step S300), and ends the support member carry-in process. That is, the control device 100 controls the head moving device 26 and the frame front-rear moving device 64 so that the transport jig 80 supported on the support rails 29 is pushed forward by the pusher 24, carried out from the working device main body 11, and stored in the storage rack 70.

[0045] Here, the correspondence between the main elements of the embodiment and the main elements of the present disclosure described in the claims will be described. Specifically, the substrate support member 90 corresponds to the support member, the working device 10 corresponds to the working device, the transport jig 80 corresponds to the transport jig, the control device 100 corresponds to the control device, the camera device 50 corresponds to the reading device, the first arm member 82a corresponds to the first arm member, the second arm member 82b corresponds to the second arm member, the first recognition mark 93c corresponds to the first read portion, and the second recognition mark 93d corresponds to the second read portion. Furthermore, the support member main body 91 corresponds to the support member main body, and the adapter 92 corresponds to the adapter. Furthermore, the recognition mark 91b corresponds to the third read portion. Furthermore, the pusher 24 corresponds to the press-down member, and the pusher lifting device 25 corresponds to the press-down member lifting device. Furthermore, the working device main body 11 corresponds to the working device main body, the storage rack 70 corresponds to the storage section, the rack lifting device 63 corresponds to the storage section lifting device, the memory device 101 corresponds to the memory section, and the recognition mark 83 corresponds to the readable section.

[0046] It goes without saying that the present disclosure is not limited to the above-described embodiments, and can be implemented in various forms as long as they fall within the technical scope of the present disclosure.

[0047] For example, in the above-described embodiment, the working device 10 is provided with two lanes for transporting and supporting the substrate S, but it may be provided with only one lane.

[0048] Furthermore, in the above-described embodiment, the working device of the present disclosure has been described as being applied to a printing device, but this is not limited to this, and the working device may be applied to any working device, such as a component mounting device, that performs work on a substrate supported by a support member and that can automatically replace the support member.

[0049] As described above, the control device of the first working device of the present disclosure reads the first and second readable portions of the support member held by the transport jig after the transport jig is loaded and determines the size of the support member relative to the transport jig. The first readable portion is provided on a third edge portion of the bottom outer edge of the support member adjacent to the first edge portion supported by the first arm, and the second readable portion is provided on a fourth edge portion of the bottom outer edge of the support member opposite the third edge portion. Therefore, by reading the first and second readable portions of the support member, the distance between the third and fourth edges, i.e., the size of the support member, can be determined. As a result, in a device in which the support member that supports a board is automatically replaceable, it is possible to determine whether the support member is appropriate with a simple configuration.

[0050] In the first working apparatus of the present disclosure, the control device may remove the support member from the transport jig and place it on the table if it determines that the size of the support member is appropriate, and may not place the support member on the table if it determines that the size of the support member is inappropriate. This makes it possible to prevent interference with other members in the working apparatus caused by placing a support member of a different size on the table.

[0051] In this case, the support member may include a support member main body that supports the substrate on its upper surface and an adapter detachably attached to the bottom surface of the support member main body, the first readable portion being provided on the third side at the outer edge of the bottom surface of the adapter, and the second readable portion being provided on the fourth side at the outer edge of the bottom surface of the adapter. By making the adapter detachable from the support member main body, even when changing the substrate to be produced, it is possible to replace only the support member main body and use the adapter as is.

[0052] Furthermore, in this case, the readable portion may be a third readable portion on the top surface of the support member body, on which information unique to the support member body is written, the reading device may be capable of reading from above and below, and the control device may place the support member on the table and then read the third readable portion with the reading device to determine whether the support member body is appropriate. In this way, it is possible to more reliably determine whether the support member body is appropriate.

[0053] Furthermore, a first working device of the present disclosure may include a press-down member and a press-down member lifting device that raises and lowers the press-down member, wherein the first arm member and the second arm member are configured to be rotatable about rotation axes that are parallel to each other, hold the support member at a predetermined rotation position where their tip ends face each other, and release the support member by being pressed down on each other, and when the control device determines that the size of the support member is appropriate, it may control the press-down member lifting device to lower the press-down member, thereby causing the press-down member to press down the first arm member and the second arm member and place the support member on the table. This allows automatic replacement of the support member with simple control.

[0054] A second working device of the present disclosure includes a working device main body, a storage unit, a storage unit lifting device, and a memory unit. The memory unit pre-stores information identifying a transport jig housed in the storage unit and information identifying a support member held by the transport jig, in association with each other, as support member information. The working device main body is capable of loading a transport jig housed in the storage unit that is at a predetermined lift position. The working device main body further includes a reading unit. When the storage unit is lifted and lowered by the storage unit lifting device and the readable portion provided on the side of the transport jig passes by the reading unit, the reading unit reads the readable portion and determines whether the support member held by the transport jig is appropriate based on the read information and the support member information stored in the memory unit. This allows a simple configuration to automatically replace support members that support substrates, and determines whether the support members are appropriate before loading a transport jig holding the support members.
