Description

Technical Field

[0001] This specification discloses a transfer jig and a working device.

Background Art

[0002] Conventionally, a working device capable of automatically exchanging a substrate support member for supporting a substrate is known. For example, in Patent Document 1, a transfer jig having a substrate support member pre-attached thereto is carried inside, the substrate support member is taken out from the carried-in transfer jig and placed on a support table, and the transfer jig after the substrate support member is taken out is carried out. A printing apparatus is disclosed. The transfer jig includes a frame body, a plurality of arm portions extending inward from the frame body, and a protrusion holding portion (recess) provided on the upper surface portion of the tip of each arm portion. The substrate support member is provided with a plurality of protrusion portions respectively held by the corresponding protrusion holding portions of the transfer jig. The printing apparatus transports (carries in) forward the transfer jig to which the substrate support member is attached so that the substrate support member is positioned above the support table. Subsequently, the printing apparatus raises the support table to lift the plurality of protrusion portions of the substrate support member from the respective protrusion holding portions of the transfer jig. Then, the printing apparatus moves the transfer jig backward and then lowers the support table, transports (carries out) the transfer jig backward, and fixes the substrate support member on the support table.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above-described working device, although the support member can be automatically exchanged using the transfer jig, in order to remove the support member from the transfer jig, it is necessary to coordinate the lifting control of the support table (table) and the transfer control of the transfer jig, resulting in a problem that the control becomes complicated.

[0005] The primary objective of this disclosure is to provide a transport jig or work device that allows for easy replacement of support members. [Means for solving the problem]

[0006] This disclosure employs the following means to achieve the primary objectives described above.

[0007] The transport jig of this disclosure is a transport jig for transporting a support member into and out of a work device that performs work on a substrate on a support member installed on a table, and comprises a pair of arm members configured to be rotatable around pivot axes extending parallel to each other, which hold the support member from both sides at a predetermined rotation position where their ends face each other, and release the hold on the support member when they are pressed against each other.

[0008] The transport jig of this disclosure comprises a pair of arm members. The pair of arm members are configured to rotate around pivot axes that extend parallel to each other. The pair of arm members hold a support member from both sides at a predetermined rotational position where their tips face each other, and release the support member by pressing down on each other. This makes it possible to move the transport jig with the support member held by the pair of arm members onto a table, and then detach the support member from the transport jig and place it on the table by pressing down on the pair of arm members. As a result, the replacement of the support member becomes easier.

[0009] The present disclosure is a work apparatus capable of performing work on a substrate on a support member installed on a table and replacing the support member using a transport jig, comprising: a pressing member; a lifting device for raising and lowering the pressing member; and a control device that controls the lifting device to lower the pressing member, thereby pressing the pair of arm members with the pressing member and placing the support member on the table, when the transport jig, which includes a pair of arm members configured to be rotatable around pivot axes extending parallel to each other and which hold the support member from both sides at a predetermined rotation position where their tips face each other and release the hold on the support member when pressed against each other, is brought above the table with the support member in place.

[0010] The work apparatus of this disclosure allows for the replacement of support members using a transport jig and comprises a pressing member, a lifting member, and a control device. When the transport jig is brought above the table, the control device controls the lifting device to lower the pressing member, thereby pressing down a pair of arm members with the pressing member and placing the support member on the table. This allows for the automatic replacement of support members with simple control. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0012] Next, the embodiments for implementing the present disclosure will be described while referring to the drawings.

[0013] FIG. 1 is a schematic configuration diagram of the working device 10 of the present disclosure. 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 block diagram showing the electrical connection relationship of the working device. 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 predetermined work on the substrate S supported by the substrate support member 90. In the present embodiment, as the predetermined work, the working device 10 uses the squeegee 22 to push the solder paste on the screen mask M into the pattern holes P1, P2 formed in the screen mask M, thereby applying (printing) the solder paste to the lower substrate S through the pattern holes P1, P2. The working device 10 is configured as a printing device. The working device 10 is combined with a mounting device for mounting electronic components on the substrate S on which solder has been printed to form a component mounting system. Further, when the working device 10 performs a setup change to change the printing target to different types of substrates S, it is possible to automatically exchange the screen mask M or automatically exchange the transfer jig 80 of the substrate support member 90.

[0015] As shown in FIGS. 1 to 4, the working device 10 includes a working device main body 11, an exchange device 60, a storage rack 70, and a control device 100. The working device main body 11 includes a head device 20 including a head 21, a support rail 29 that supports a screen mask M and a transfer jig 80, first and second substrate transfer and support devices 30 and 40 that transfer and support a substrate S by a dual lane, and a camera device 50. Further, the working device 10 is provided in front of the working device main body 11 and also includes an operation panel that displays various information and enables various input operations by an operator.

[0016] The head device 20 is installed in the 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-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-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 by, for example, an air cylinder, a pusher 24, and a pusher lifting device 25 that raises and lowers the pusher 24 by, for example, an air cylinder. The squeegee 22 is a plate-like member extending in the left-right direction (X-axis direction) orthogonal to the printing direction. The pusher 24 moves back and forth by the head moving device 26 in a state where it descends by the pusher lifting device 25 and protrudes downward, and thereby pushes the screen mask M and the transfer jig 80 on the support rail 29 back and forth for transfer. Further, when replacing the substrate support member 90 using the transfer jig 80, the pusher 24 also recovers the substrate support member 90 on the tables 36 and 46 into the transfer jig 80 carried onto the support rail 29, or removes the substrate support member 90 from the transfer jig 80 carried onto the support rail 29 while holding the substrate support member 90 and places it on the tables 36 and 46.

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

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

[0019] The first and second substrate transport and support devices 30 and 40 transport and support substrates S, and also bring the supported substrates S into contact with and separate from the screen mask M on the support rail 29. As shown in Figures 2 to 4, the first and second substrate transport and support devices 30 and 40 include conveyor devices 31 and 41, conveyor spacing changing devices 34 and 44, conveyor lifting devices 35 and 45, tables 36 and 46, and support member lifting devices 37 and 47. The conveyor devices 31 and 41 have conveyor belts provided on a pair of front and rear side frames 33s and 43s, respectively, and motors that drive the conveyor belts in a circular motion. The pair of side frames 33s and 43s are erected on the base frames 33b and 43b, and substrate guides 32 and 42 are provided at the upper ends of the pair of side frames 33s and 43s. The conveyor spacing changing devices 34 and 44 change (adjust) the spacing of the conveyor belt by moving one or both of the pair of side frames 33s and 43s closer together or further apart. This allows the first and second substrate transport and support devices 30 and 40 to transport and support substrates S of different sizes. The conveyor lifting devices 35 and 45 raise and lower the conveyor devices 31 and 41 (conveyor belts) by raising and lowering the support columns that support the base frames 33b and 43b. The tables 36 and 46 are support bases having an upper surface on which a substrate support member 90 can be installed. The support member lifting devices 37 and 47 raise and lower the substrate support member 90 installed on the tables 36 and 46 by raising and lowering the support columns that support the tables 36 and 46.

[0020] The substrate support member 90 supports the substrate S from below and is replaced according to the substrate S. As shown in Figure 5, a positioning mark 91 is formed on the bottom surface of the substrate support member 90 for positioning the substrate support member 90 relative to the tables 36 and 46 when replacing the substrate support member 90.

[0021] As shown in Figures 1 and 2, the camera device 50 comprises a camera body 51 and a camera moving device 55 that moves the camera body 51 in the forward, backward, left, and right directions (XY direction). The camera moving device 55 has 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 a long member that extends left and right and is spanned 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 the 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 (upper reading section 52, lower reading section 53) vertically. The camera device 50 acquires the position of the substrate S by imaging the marks formed on the upper surface of the substrate S, which has been transported and supported by the first and second substrate transport and support devices 30 and 40, with the lower reading unit 53. The camera device 50 also acquires the position of the substrate support member 90 by imaging the marks (positioning marks 91) formed on the bottom surface of the substrate support member 90, which has been transported onto the support rail 29 together with the transport jig 80, with the upper reading unit 52.

[0022] The replacement device 60 receives a storage rack 70 containing replacement components such as a screen mask M and a transport jig 80, and transports the replacement components between the storage rack 70 and the work device body 11. The replacement device 60 comprises a left unit 61a installed on the left side of the front of the work device body 11, and a right unit 61b installed on the right side of the front of the work device body 11. The left unit 61a and the right unit 61b each have a rack support member 62 that receives the storage rack 70 and supports its lower surface 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 by 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 movement device 64 that moves the frame of the replacement member in the storage rack 70 forward and backward from both the left and right sides using belts, rollers, etc.

[0023] The storage rack 70 has multiple rows of left and right support rails 71 arranged vertically, and each support rail 71 is a storage unit capable of accommodating replacement parts. Openings 72 and 73 are formed on the front and back of the storage rack 70 and the work device body 11. Replacement parts are loaded and unloaded by an operator through the front opening 72, and moved in and out by the frame forward / backward movement device 64 through the rear opening 73. With the storage rack 70 received by the replacement device 60, the frame forward / backward movement device 64 sends the replacement parts supported on the support rails 71 of the storage rack 70 that are located at approximately the same height as the support rails 29 of the work device body 11, via the rack lifting device 63, to the work device body 11. The frame forward / backward movement device 64 also sends the replacement parts supported on the support rails 29 of the work device body 11 to the support rails 71 of the storage rack 70 that are located 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 it may be loaded onto an automated guided vehicle (AGV) and automatically transported to the receiving position of the exchange device 60 by the AGV.

[0024] The transport jig 80 is a jig used for loading and unloading substrate support members 90, and as shown in Figures 6 and 7, it comprises a rectangular frame 81 and a pair of arm members 82 fixed to the frame 81 so that their ends face each other and hold the substrate support members 90 from both sides. In this embodiment, the transport jig 80 has two sets of pairs of arm members 82 for holding the substrate support members 90, and each set is capable of transporting the substrate support members 90 used in the first and second substrate transport support devices 30 and 40 at once.

[0025] Each arm member 82, as shown in Figure 8, includes a base member 821, an arm plate 822, a retaining member 823, a side plate 825, a lock plate 826, and a lock block 827. For ease of understanding the configuration, the front side plate 825 and lock plate 826 are shown with dashed lines in Figure 8. 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 the retaining member 823 is rotatably attached to the tip 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 the retaining member 823 is rotatably attached to the tip of the side plate 825. Furthermore, the side plate 825 biases the arm plate 822 upward by the biasing force of the torsion coil spring 824 provided on the pivot axis on the base member 821 side. The side plate 825 is also positioned 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 abuts against the short side portion of the bottom outer edge of the substrate support member 90, holding 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 and 46 above the tables 36 and 46 as the arm plates 822 of the pair of arm members 82 are pressed down and spread apart.

[0026] The locking plate 826 locks the arm plate 822 so that it cannot be pressed. The locking plates 826 are positioned on both sides of the arm plate 822, and a locking block 827 is fixed between the two locking plates 826 so as to be located below the arm plate 822. The base end of the locking plate 826 is rotatably mounted on the base member 821 at a position eccentric with respect to the pivot axis on the base end side of the arm plate 822, and is pulled toward the arm plate 822 by the biasing force of a tension spring 828 that is engaged with the locking plate 826 and the arm plate 822 at the tip side of the base end. The locking block 827 locks the arm plate 822 so that it cannot be pressed by engaging with a notch 822c formed on the lower surface of the arm plate 822. Furthermore, the tips of both locking plates 826 protrude upward from the arm plate 822 when the locking block 827 is engaged with the notch 822c of the arm plate 822.

[0027] In the arm member 82 configured in this way, the arm plate 822 is locked in place so that it cannot be pushed down by the biasing force of the tension spring 828 causing the lock block 827 to engage with the notch 822c of the arm plate 822. Therefore, even if an unintended force is applied to the substrate support member 90 or the arm plate 822, the arm member 82 (arm plate 822) will not be pushed down, and the substrate support member 90 will not detach. The lock of the lock plate 826 can be released by pressing the tip of the lock plate 826 that protrudes above the arm plate 822.

[0028] The lock plate 826 is unlocked and the arm plate 822 is pushed down by a single pusher 24. As shown in Figures 9 and 10, the pusher 24 has a pair of front and rear pusher plates 241 positioned on the left and right sides at a distance corresponding to the distance between the pair of arm members 82, and a pusher roller 242 positioned 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 pushed down by the pusher plates 241 (see Figure 11). When the tip of the lock plate 826 is pushed 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 Figure 12). This unlocks the arm plate 822. As the pusher 24 descends further, the pusher roller 242 comes into contact with the arm plate 822, and the arm plate 822 is pushed down by the pusher roller 242 (see Figure 13). 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 detaches from the arm members 82.

[0029] The control device 100 is configured as a microprocessor centered around a CPU, and in addition to the CPU, it includes ROM, RAM, input / output ports, etc. The control device 100 exchanges signals with the head device 20, the first and second substrate transport support devices 30 and 40, the camera device 50, the exchange device 60, etc. The control device 100 is also communicatively connected to the management device 200, which 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.

[0030] The operation of the work apparatus 10 configured in this way will be explained. In particular, the operation of changing the setup to replace the screen mask M and the substrate support member 90 will be explained. The setup change is performed by setting the storage rack 70 in the exchange device 60 and executing the mask unloading process, the support member unloading process, the support member loading process, and the mask loading process in this order.

[0031] The mask unloading process involves unloading the screen mask M, which is supported by the support rails 29 of the work 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 work device body 11. Next, the control device 100 controls the head moving device 26 so that the screen mask M, supported by the support rails 29, is pushed forward by the pusher 24 and unloaded from the work device body 11. Then, the control device 100 controls the frame forward / backward 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 operation of the mask unloading process, so its explanation is omitted.

[0032] The support member unloading process involves using a transport jig 80 to unload the substrate support members 90 from the tables 36 and 46 of the work device body 11 and storing them in the storage rack 70. The support member loading process involves using the transport jig 80 to load the substrate support members 90 from the storage rack 70 and placing them on the tables 36 and 46 of the work device body 11. Figure 14 is a flowchart showing an example of the support member loading process executed by the control device 100. Note that the support member unloading process is basically performed by the reverse operation of the support member loading process, so its explanation is omitted.

[0033] In the support member loading process, the control device 100 first controls the transport jig 80 holding the two substrate support members 90 to be replaced to be transported above the tables 36 and 46 of the first and second substrate transport support devices 30 and 40 (step S100). Specifically, the control device 100 controls the rack lifting device 63 so that the storage rack 70 rises until the support rail 71 supporting the transport jig 80 to be loaded is at approximately the same height as the support rail 29 of the work device body 11. Next, the control device 100 controls the frame forward / backward movement device 64 so that the transport jig 80 is fed from the storage rack 70 to the support rail 29. Then, the control device 100 controls the pusher lifting device 25 to lower the pusher 24 and the head movement device 26 so that the pusher 24 pushes the transport jig 80 on the support rail 29 backward for loading.

[0034] When the transport jig 80 is brought in, the control device 100 controls the camera device 50 to read the positioning marks 91 on the substrate support members 90 held by the transport jig 80 using the upper reading unit 52 of the camera body 51 (step S110). Then, based on the position of the read positioning marks 91, the control device 100 corrects the position of the transport jig 80 so that the two substrate support members 90 held by the transport jig 80 are positioned directly above each table 36, 46 (step S120). In other words, the control device 100 fine-tunes the position of the transport jig 80 by controlling the head moving device 26 to push the transport jig 80 forward or backward with the pusher 24.

[0035] Next, the control device 100 controls the support member lifting device 37 or 47 so that the table 36 or 46 rises to the printing height (step S130). Subsequently, the control device 100 controls the pusher lifting device 25 so that the pusher 24 descends directly above the raised table (step S140) and waits for a predetermined time to elapse (step S150). Here, the predetermined time is the waiting time until the substrate support member 90 detaches from the transport jig 80 and is placed on the table 36 or 46. As described above, when the pusher 24 descends, the left and right pair of pusher plates 241 first come into contact with the lock plates 826 of the corresponding arm members 82 and press them down, releasing the lock of the arm plates 822. Then, as the pusher 24 descends further, the left and right pair of pusher rollers 242 come into contact with the corresponding arm plates 822 and press them down, spreading the pair of arm members 82 apart. As a result, the substrate support member 90 detaches from the pair of arm members 82 and is placed on the table. In this way, the substrate support member 90 can be detached from the transport jig 80 and placed on the table by simple control, which only involves lowering the pusher 24 from directly above the pair of arm members 82. Furthermore, the control device 100 reads the positioning marks 91 with the camera device 50 and corrects the position of the substrate support member 90 before placing the substrate support member 90 on the table, thereby more reliably suppressing positional displacement of the substrate support member 90 when it is placed on the table.

[0036] 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 S160). The control device 100 then places the other substrate support member 90, held by the transport jig 80, onto the other table using similar control. The control device 100 then moves the transport jig 80, from which the two substrate support members 90 have been removed, to the storage rack 70 (step S170), thus ending the support member loading process. In other words, the control device 100 controls the head moving device 26 and the frame forward / backward moving device 64 so that the transport jig 80, supported by the support rail 29, is pushed forward by the pusher 24 and moved out of the work device body 11, and then stored in the storage rack 70.

[0037] Here, the correspondence between the main elements of the embodiment and the main elements of the disclosure as described in the claims will be explained. Specifically, the substrate support member 90 corresponds to the support member, the work device 10 corresponds to the work device, the transport jig 80 corresponds to the transport jig, and the pair of arm members 82 corresponds to the pair of arm members. The arm plate 822 corresponds to the arm member body, and the notch 822c of the arm plate 822, the lock plate 826, the lock block 827, and the tension spring 828 correspond to the locking mechanism. The lock plate 826 and the lock block 827 correspond to the lock piece, the tension spring 828 corresponds to the biasing member, and the notch 822c of the arm plate 822 corresponds to the engaged portion. The pusher 24 corresponds to the pressing member, the pusher lifting device 25 corresponds to the lifting device, and the control device 100 corresponds to the control device. Furthermore, the pusher plate 241 corresponds to the first pressing portion, and the pusher roller 242 corresponds to the second pressing portion. In addition, the head moving device 26 corresponds to the moving device, and the camera device 50 corresponds to the position detection device.

[0038] It goes without saying that this disclosure is not limited in any way to the embodiments described above, and can be implemented in various forms as long as they fall within the technical scope of this disclosure.

[0039] For example, in the embodiment described above, the work apparatus 10 is provided with two lanes for transporting and supporting the substrate S, but it may also be provided with only one lane.

[0040] Furthermore, although the above-described embodiments explained the application of the work apparatus of this disclosure to a printing apparatus, it is not limited thereto. It may be applied to any work apparatus that performs work on a substrate supported by a support member, such as a component mounting apparatus, and in which the support member can be automatically replaced.

[0041] As described above, the transport jig of this disclosure comprises a pair of arm members. The pair of arm members are configured to be rotatable around pivot axes that extend parallel to each other. The pair of arm members hold a support member from both sides at a predetermined rotational position where their tips face each other, and release the hold on the support member by pressing down on each other. This makes it possible to move the transport jig with the support member held by the pair of arm members onto the table, and then detach the support member from the transport jig and place it on the table by pressing down on the pair of arm members. As a result, the replacement of the support member becomes easier.

[0042] In the transport jig of this disclosure, each of the pair of arm members may have an arm member body that is rotatable about the pivot axis and holds the support member at a predetermined rotation position, and a locking mechanism that locks the arm member body at the predetermined rotation position. This prevents the support member from being released even if an unintended force is applied to the support member or the arm member body.

[0043] Furthermore, in the conveying jig of this disclosure, the locking mechanism includes a locking piece that is rotatable independently of the arm member body, and a biasing member that biases the locking piece in one direction in the rotational direction. The arm member body is locked when the locking piece engages with an engaging portion formed on the arm member body due to the biasing force of the biasing member, and the lock on the arm member body is released when the locking piece is pushed in the other direction in the rotational direction against the biasing force of the biasing member to release the engagement of the locking piece. In this way, a pushing operation can be used to push the locking piece to release the lock on the arm member body by the locking piece, while simultaneously pushing the arm member body to release the support member from being held by the arm member body.

[0044] The work apparatus of this disclosure allows for the replacement of support members using a transport jig and comprises a pressing member, a lifting member, and a control device. When the transport jig is brought above the table, the control device controls the lifting device to lower the pressing member, thereby pressing down a pair of arm members with the pressing member and placing the support member on the table. This allows for the automatic replacement of support members with simple control.

[0045] In the work apparatus of the present disclosure, each of the pair of arm members comprises an arm member body that is rotatable about the pivot axis and holds the support member at a predetermined rotation position, and a locking mechanism that locks the arm member body at the predetermined rotation position, wherein the locking mechanism comprises a locking piece that is rotatable independently of the arm member body, and a biasing member that biases the locking piece in one direction in the rotation direction, and the biasing force of the biasing member causes the locking piece to engage with an engaging portion formed on the arm member body. The arm member body is locked by pressing the locking piece, and the lock is released when the locking piece is pushed in the other direction in the rotational direction against the biasing force of the biasing member so that the engagement of the locking piece is released. The pressing member has a first pressing part that presses the locking piece and a second pressing part that presses the arm member body. By lowering the lifting device, the first pressing part presses the locking piece, and by lowering the lifting device further, the second pressing part presses the arm member body. In this way, by pressing the pressing member, the locking piece is pressed to release the lock on the arm member body by the locking piece, while the arm member body is pressed to release the holding of the support member by the arm member body.

[0046] Furthermore, the work apparatus of this disclosure may include a moving device for moving the table and the transport jig relative to each other, and a position detection device for detecting the position of the support member. The control device may, when the transport jig holding the support member is brought in, control the moving device based on the position of the support member detected by the position detection device to align the support member and the table, and then control the lifting device to lower the pressing member so that the support member is placed on the table. This makes it possible to more reliably suppress misalignment of the support member placed on the table. The moving device may be one that moves the transport jig, or it may be one that moves the table. [Industrial applicability]
