Description

[Technical Field]

[0001] The present specification discloses a transport jig and a working 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 protrusion holders (recesses) disposed on the top surfaces of the tips of the arms. The substrate support member has multiple protrusions that are each held by the corresponding protrusion holders of the transport jig. The printing device transports (loads) the transport jig with the attached substrate support member forward so that the substrate support member is positioned above the support table. The printing device then raises the support table to lift the multiple protrusions of the substrate support member off the respective protrusion holders of the transport jig. Then, the printing apparatus moves the transport jig rearward and then lowers the support table, transporting (carrying out) the transport jig rearward, and fixes the substrate support member onto the support table.

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

[0004] Although the above-mentioned working device can automatically replace the support member using a transport jig, there is a problem in that the control of lifting and lowering the support table and the transport control of the transport jig must be coordinated in order to remove the support member from the transport jig, which makes the control more complicated.

[0005] A primary object of the present disclosure is to provide a transport jig or working device that allows for easy replacement of a support member. [Means for solving the problem]

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

[0007] The transport jig disclosed herein 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 placed on a table, and is configured to be rotatable around a rotation axis extending parallel to each other, and is equipped with a pair of arm members that hold the support member from both sides at a predetermined rotation position where their tip ends face each other, and release their hold on the support member by being pressed down on each other.

[0008] The transport jig of this disclosure includes a pair of arm members. The pair of arm members are configured to be rotatable about rotation axes extending parallel to each other. The pair of arm members hold the support member from both sides at a predetermined rotation position where their tip ends face each other, and release their hold on the support member by being pressed down on each other. This allows the transport jig, with the support member held by the pair of arm members, to be carried above the table, and by pressing down the pair of arm members, the support member can be detached from the transport jig and placed on the table. This makes it easy to replace the support member.

[0009] The gist of the working device disclosed herein is a working device that can perform work on a substrate on a support member placed on a table and can replace the support member using a transport jig, and includes: a press-down member; a lifting device that raises and lowers the press-down member; and a control device that, when the transport jig is carried above the table while holding the support member, controls the lifting device to lower the press-down member, causing the press-down member to press down the pair of arm members, thereby placing the support member on the table.

[0010] The working device disclosed herein is capable of replacing a support member using a transport jig and includes a press-down member, a lifting member, and a control device. When the transport jig is carried above a table, the control device controls the lifting device to lower the press-down member, causing the press-down member to press down a pair of arm members and place the support member on the table. This allows automatic replacement of the support member with simple control. [Brief explanation of the drawings]

[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, and a camera device 50. 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 substrate support member 90 supports the substrate S from the underside and is replaced depending on the substrate S. As shown in Fig. 5, a positioning mark 91 is formed on the bottom surface of the substrate support member 90 to position the substrate support member 90 relative to the tables 36, 46 when replacing the substrate support member 90.

[0021] 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 top surface of the substrate S carried in and supported by the first and second substrate transport and support devices 30, 40 with the lower reading unit 53. The camera device 50 also acquires the position of the substrate support member 90 by capturing an image of a mark (positioning mark 91) formed on the bottom surface of the substrate support member 90 carried in together with the transport jig 80 onto the support rails 29 with the upper reading unit 52.

[0022] 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.

[0023] 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.

[0024] 6 and 7, 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 fixed to the frame body 81 with their tips facing each other and holding 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.

[0025] As shown in FIG. 8 , each arm member 82 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 indicated by dashed lines in FIG. 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 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 abuts against the short side portion of 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 tip ends (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 when the arm plates 822 of the pair of arm members 82 are pressed down and spread apart above the tables 36, 46.

[0026] 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.

[0027] 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.

[0028] 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. 9 and 10 , 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. 11 ). 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. 12 ). 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 pushed down by the pusher roller 242 (see FIG. 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 is detached 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, is equipped with ROM, RAM, 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, etc. The control device 100 is also communicatively 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.

[0030] 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.

[0031] 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.

[0032] 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. Figure 14 is a flowchart 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.

[0033] In the support member carry-in process, the control device 100 first controls the transport jig 80 holding the two substrate support members 90 to be replaced so that it is transported above the tables 36, 46 of the first and second substrate transport and support devices 30, 40 (step S100). Specifically, the control device 100 controls the rack lifting device 63 so that the storage rack 70 rises until the support rails 71 supporting the transport jig 80 to be carried in are at substantially the same height as the support rails 29 of the working device main body 11. Next, the control device 100 controls the frame front-rear moving device 64 so that the transport jig 80 is sent from the storage rack 70 to the support rails 29. The control device 100 then controls the pusher lifting device 25 to lower the pusher 24, and controls the head moving device 26 so that the pusher 24 pushes the transport jig 80 on the support rails 29 backward to carry it in.

[0034] When the transport jig 80 is carried in, the control device 100 controls the camera device 50 so that the upper reading unit 52 of the camera body 51 reads the positioning marks 91 on the substrate support members 90 held by the carried-in transport jig 80 (step S110). Then, based on the positions 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 of the tables 36, 46 (step S120). That is, the control device 100 controls the head moving device 26 to push the transport jig 80 forward or backward with the pusher 24, thereby fine-tuning the position of the transport jig 80.

[0035] Next, the control device 100 controls the support member lifting device 37 or 47 so that the table 36 or 46 is raised to the printing height (step S130). Subsequently, the control device 100 controls the pusher lifting device 25 so that the pusher 24 is lowered 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 is detached from the transport jig 80 and placed on the table 36 or 46. As described above, when the pusher 24 descends, first, the pair of left and right pusher plates 241 abut against and press down on the lock plates 826 of the corresponding 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 abut against and press down on the corresponding arm plates 822, thereby pushing the pair of arm members 82 apart. 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, the substrate support member 90 can be detached from the transport jig 80 and placed on the table by simply controlling the pusher 24 to lower from directly above the pair of arm members 82. Furthermore, before placing the substrate support member 90 on the table, the control device 100 reads the positioning mark 91 with the camera device 50 and corrects the position of the substrate support member 90, which more reliably prevents the substrate support member 90 from becoming misaligned 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 similarly controls the other substrate support member 90 held by the transport jig 80 to be placed on the other table. The control device 100 then transports the transport jig 80, from which the two substrate support members 90 have been removed, to the storage rack 70 (step S170), thereby completing the support member loading process. Specifically, 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, removed from the working device main body 11, and stored in the storage rack 70.

[0037] 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 a support member, the working device 10 corresponds to a working device, the transport jig 80 corresponds to a transport jig, and the pair of arm members 82 correspond to a pair of arm members. The arm plate 822 corresponds to an arm member main 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 a lock mechanism. The lock plate 826 and the lock block 827 correspond to a lock piece, the tension spring 828 corresponds to a biasing member, and the notch 822c of the arm plate 822 corresponds to an engaged portion. The pusher 24 corresponds to a pressing member, the pusher lifting device 25 corresponds to a lifting device, and the control device 100 corresponds to a control device. Moreover, the pusher plate 241 corresponds to a first depressing portion, and the pusher roller 242 corresponds to a second depressing portion. Moreover, the head moving device 26 corresponds to a moving device, and the camera device 50 corresponds to a position detecting device.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] As described above, the transport jig of the present disclosure includes a pair of arm members. The pair of arm members are configured to be rotatable about rotation axes extending parallel to each other. The pair of arm members hold the support member from both sides at a predetermined rotation position where their tip ends face each other, and release their hold on the support member by being pressed down on each other. This makes it possible to carry the transport jig with the support member held by the pair of arm members above the table, and by pressing down the pair of arm members, the support member can be detached from the transport jig and placed on the table. As a result, replacement of the support member becomes easy.

[0042] In the transport jig of the present disclosure, each of the pair of arm members may have an arm member main body that is rotatable about the rotation axis and that holds the support member at the predetermined rotation position, and a locking mechanism that locks the arm member main body at the predetermined rotation position. This makes it possible to prevent the support member from being released from its hold even if an unintended force acts on the support member or the arm member main body.

[0043] Furthermore, in the transport jig disclosed herein, the locking mechanism may have a locking piece that is rotatable independently of the arm member main body, and a biasing member that biases the locking piece in one direction in a rotational direction, wherein the biasing force of the biasing member causes the locking piece to engage with an engaged portion formed on the arm member main body, thereby locking the arm member main body, and the locking piece is released when the locking piece is pressed 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. In this way, by a pressing operation, the locking piece can be pressed down to release the lock of the arm member main body by the locking piece, and the arm member main body can be pressed down to release the hold of the support member by the arm member main body.

[0044] The working device disclosed herein is capable of replacing a support member using a transport jig and includes a press-down member, a lifting member, and a control device. When the transport jig is carried above a table, the control device controls the lifting device to lower the press-down member, causing the press-down member to press down a pair of arm members and place the support member on the table. This allows automatic replacement of the support member with simple control.

[0045] In the working device of the present disclosure, the pair of arm members each have an arm member main body that is rotatable around the rotation axis and that holds the support member at the predetermined rotation position, and a locking mechanism that locks the arm member main body at the predetermined rotation position, the locking mechanism having a locking piece that is rotatable independently of the arm member main body, and a biasing member that biases the locking piece in one direction in a rotation direction, and the biasing force of the biasing member causes the locking piece to engage with an engaged portion formed on the arm member main body. the pressing member may have a first pressing portion that presses down the locking piece and a second pressing portion that presses down the arm member body, and may be lowered by the lifting device to press down the locking piece with the first pressing portion, and may be further lowered by the lifting device to press down the arm member body with the second pressing portion. In this way, by pressing down the pressing member, the locking piece is pressed down to release the lock of the arm member body by the locking piece, and the arm member body is pressed down to release the holding of the support member by the arm member body.

[0046] The working apparatus of the present disclosure may further include a moving device that moves the table and the transport jig relative to each other, and a position detection device that detects the position of the support member, and the control device may control the moving device to align the support member with the table based on the position of the support member detected by the position detection device when the transport jig holding the support member is carried in, and then control the lifting device to lower the press-down member so that the support member is placed on the table. This more reliably prevents misalignment of the support member placed on the table. The moving device may move the transport jig or the table. [Industrial Applicability]
