Conveying clamp and working device

Abstract

A conveyance jig is used to carry in and out a support member for a substrate set on a worktable with respect to a work device that performs work on the substrate. The conveyance jig has a pair of arm members. The pair of arm members are configured to be able to rotate around a rotation axis that extends in parallel with each other. Also, the pair of arm members hold the support member from both sides at a predetermined rotation position where the front end portions of the pair of arm members face each other, and release the holding of the support member by being pressed down against each other.

Description

Technical Field

[0001] This manual discloses the conveying clamp and the working device. Background Technology

[0002] Conventional work devices capable of automatically replacing substrate support components for supporting substrates are known. For example, Patent Document 1 discloses a printing apparatus that moves a transport jig pre-installed with a substrate support component inward, removes the substrate support component from the transport jig after it has been moved in, places it on a support table (worktable), and then moves the transport jig out after removing the substrate support component. The transport jig has a frame, multiple arms extending inward from the frame, and protrusion holding portions (recesses) disposed on the upper surface of the top of each arm. The substrate support component is provided with multiple protrusions, each held by a corresponding protrusion holding portion of the transport jig. The printing apparatus moves (moves in) the transport jig with the substrate support component mounted on it forward so that the substrate support component is positioned above the support table. Next, the printing apparatus raises the support table, causing the multiple protrusions of the substrate support component to float from each protrusion holding portion of the transport jig. Then, the printing apparatus moves the transport jig backward and lowers the support table, moving (moves out) the transport jig backward and fixing the substrate support component on the support table.

[0004] Patent Document 1: International Publication No. 2016 / 199207 Summary of the Invention

[0005] The problem that the invention aims to solve

[0006] In the aforementioned working device, although the support components can be automatically replaced using a conveyor clamp, in order to remove the support components from the conveyor clamp, it is necessary to coordinate the lifting control of the support table (workbench) and the conveying control of the conveyor clamp, which leads to the problem of control complexity.

[0007] The main objective of this disclosure is to provide a conveying clamp or working device that allows for easy replacement of support components.

[0008] Methods for solving problems

[0009] The following means are employed in this disclosure to achieve the aforementioned principal objectives.

[0010] The present disclosure discloses a conveying fixture for moving the support member into and out relative to a working device for working on a support member provided on a worktable. Its main feature is that it has a pair of arm members configured to rotate about a rotation axis extending parallel to each other, holding the support member from both sides at a predetermined rotation position opposite each other at their front ends, and releasing the holding of the support member by pressing them down.

[0011] The disclosed conveying fixture includes a pair of arm members. The pair of arm members are configured to rotate about mutually parallel rotating axes. Furthermore, the pair of arm members hold support members from both sides at predetermined rotational positions opposite each other at their front ends, and release the support members by pressing them down. Thus, by moving the conveying fixture, with the support members held by the pair of arm members, upwards onto the worktable and pressing down the pair of arm members, the conveying fixture can be detached from the support members and placed on the worktable. As a result, the replacement of the support members becomes easy.

[0012] The disclosed working apparatus operates on a substrate mounted on a support member of a worktable and can replace the support member using a transport clamp. Its main feature is that it includes: a pressing member; a lifting device for raising and lowering the pressing member; and a control device that, when a transport clamp including a pair of arm members, holding the support member, is moved above the worktable, the control device controls the lifting device to lower the pressing member. Thus, the pressing member presses down the pair of arm members, placing the support member on the worktable. The pair of arm members are configured to rotate about mutually parallel rotating axes, holding the support member from both sides at predetermined rotational positions opposite each other at their front ends, and releasing the holding of the support member by pressing them down.

[0013] The disclosed working device enables the replacement of support components using a conveyor clamp, and includes a pressing component, a lifting component, and a control device. With the conveyor clamp positioned above the worktable, the control device controls the lifting device to lower the pressing component, thereby pressing down a pair of arm components and placing the support components on the worktable. This allows for automatic replacement of the support components through simple control. Attached Figure Description

[0028] Next, while referring to the appendix Figure 1 The manner in which this disclosure is implemented will be described.

[0029] Figure 1 This is a schematic structural diagram of the operating device 10 disclosed herein. Figure 2 This is a perspective view showing the internal structure of the working device 10. Figure 3 This is a side view showing the internal structure of the working device 10. Figure 4 This is a block diagram showing the electrical connections of the working device. Figures 1-3 In the diagram, the left and right directions are set as the X-axis, the front and back directions as the Y-axis, and the up and down directions as the Z-axis.

[0030] The workpiece apparatus 10 performs a predetermined operation on the substrate S supported by the substrate support member 90. In this embodiment, the workpiece apparatus 10 is configured as a printing apparatus that, as a predetermined operation, uses a squeegee 22 to press solder paste on the screen mask M into the pattern holes P1 and P2 formed on the screen mask M, thereby applying (printing) solder paste onto the substrate S below through the pattern holes P1 and P2. The workpiece apparatus 10, combined with a mounting apparatus for mounting electronic components onto the solder-printed substrate S, constitutes a component mounting system. Furthermore, when performing changeover adjustments to change the printing target to a different type of substrate S, the workpiece apparatus 10 can automatically change the screen mask M and automatically change the substrate support member 90 using the transport fixture 80.

[0031] like Figures 1-4 As shown, the work device 10 includes: a work device main body 11, a changing device 60, a receiving rack 70, and a control device 100. The work device main body 11 includes: a head device 20 including a head 21, a support rail 29 supporting a screen mask M and a conveying fixture 80, first and second substrate conveying support devices 30 and 40 for conveying and supporting substrate S through dual channels, and a camera device 50. In addition, the work device 10 also has an operation panel provided on the front of the work device main body 11, which displays various information and enables various input operations by the operator.

[0032] The head device 20 is located on the upper layer of the main body 11 of the working device. For example... Figure 1 As shown, the head assembly 20 includes a head 21 and a head moving device 26 that moves the head 21 in the printing direction, i.e., the front-to-back direction (Y-axis direction). The head moving device 26 has a Y-axis slider 27 that moves along a guide rail 28 extending in the front-to-back direction and a motor that drives the Y-axis slider 27. The head 21 includes: a squeegee 22, a squeegee lifting device 23 that uses a cylinder to lift the squeegee 22, a pusher 24, and a pusher lifting device 25 that uses a cylinder to lift the pusher 24. The squeegee 22 is a plate-shaped member that extends in the left-to-right direction (X-axis direction) orthogonal to the printing direction. The pusher 24, in a state of being lowered and protruding downward by the pusher lifting device 25, moves back and forth by the head moving device 26, pushing and conveying the screen mask M and the transport fixture 80 on the support rail 29 back and forth. In addition, when using the conveyor clamp 80 to replace the substrate support member 90, the pusher 24 is also used to retract the substrate support member 90 on the worktables 36 and 46 to the conveyor clamp 80 that is moved into the support rail 29, remove the substrate support member 90 from the conveyor clamp 80 that is moved into the support rail 29 while holding the substrate support member 90, and place it on the worktables 36 and 46.

[0033] The screen mask M is a thin metal sheet fixed to a rectangular frame F under predetermined tension. Patterned holes P1 and P2 are formed in the screen mask M for printing solder onto the substrates S, which are conveyed and supported by the first and second substrate conveying support devices 30 and 40, respectively.

[0034] like Figure 3 As shown, the support rails 29 are a pair of left and right rails extending in the front-back direction (Y-axis direction), and are disposed 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 or transport fixture 80 in a horizontal position and guide the screen mask M or transport fixture 80, which is pushed by the pusher 24, to move in the front-back direction.

[0035] The first and second substrate transport and support devices 30 and 40 move and support the substrate S, and cause the supported substrate S to contact and separate from the screen mask M on the support track 29. Figures 2-4 As shown, the first and second substrate conveying support devices 30 and 40 include: conveyor devices 31 and 41, conveyor interval changing devices 34 and 44, conveyor lifting devices 35 and 45, worktables 36 and 46, and support component lifting devices 37 and 47. The conveyor devices 31 and 41 have conveyor belts respectively disposed on a pair of front and rear side frames 33s and 43s, and motors for driving the conveyor belts in a circular motion. A pair of side frames 33s and 43s are erected on 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 interval changing devices 34 and 44 change (adjust) the interval of the conveyor belts by bringing one or both of the pair of side frames 33s and 43s closer together or apart. Thus, the first and second substrate conveying support devices 30 and 40 can convey and support substrates S of different sizes. Conveyor lifting devices 35 and 45 raise and lower conveyor devices 31 and 41 (conveyor belts) by raising and lowering the supports of the supporting base frames 33b and 43b. Worktables 36 and 46 are support platforms with mounting surfaces on their upper surfaces capable of housing substrate support members 90. Support member lifting devices 37 and 47 raise and lower the substrate support members 90 mounted on the worktables 36 and 46 by raising and lowering the supports of the worktables 36 and 46.

[0036] The substrate support member 90 supports the substrate S from the lower surface side and is replaceable depending on the substrate S. For example... Figure 5 As shown, 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 worktables 36 and 46 when the substrate support member 90 is replaced.

[0037] like Figure 1 and Figure 2As shown, the camera device 50 includes a camera body 51 and a camera moving device 55 that moves the camera body 51 forward, backward, left, and right (XY directions). The camera moving device 55 includes an X-axis slider 56, a motor driving the X-axis slider 56, a Y-axis slider 58, and a motor driving the Y-axis slider 58. The Y-axis slider 58 is a long strip extending left and right and mounted on a pair of left and right Y-axis guide rails 59, moving forward and backward 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 shooting fields (upper reading section 52 and lower reading section 53) at the top and bottom. The camera device 50 uses the lower reading section 53 to capture images of the marks formed on the upper surface of the substrate S, which is moved and supported by the first and second substrate transport support devices 30 and 40, to obtain the position of the substrate S. In addition, the camera device 50 uses the upper reading unit 52 to capture the mark (positioning mark 91) formed on the bottom surface of the substrate support member 90 that is moved into the support track 29 together with the transport jig 80, thereby obtaining the position of the substrate support member 90.

[0038] The changing device 60 receives a storage rack 70 containing a changing component such as a screen mask M or a conveyor clamp 80, and transports the changing component between the storage rack 70 and the main body 11 of the working device. The changing device 60 includes a left unit 61a located on the left side of the front surface of the main body 11 of the working device and a right unit 61b located on the right side of the front surface of the main body 11 of the working device. The left unit 61a and the right unit 61b have a frame support member 62 that receives the storage rack 70 and supports its lower surface from both sides, and a frame lifting device 63 that raises and lowers the frame support member 62. The frame lifting device 63 is, for example, a combination of a ball screw mechanism and an electric motor, or a linear motor. The storage rack 70, supported by the frame support member 62, is raised and lowered together with the frame support member 62 via the frame lifting device 63. Furthermore, the left unit 61a and the right unit 61b have a frame forward and backward movement device 64 that transports the frame of the changing component within the storage rack 70 from both sides forward and backward using a belt, roller, or the like.

[0039] The storage rack 70 is a housing with multiple layers of horizontally paired support rails 71, capable of accommodating replacement parts on each support rail 71. Openings 72 and 73 are formed on the front and back surfaces of the working device body 11 of the storage rack 70. Replacement parts are taken out and placed by the operator through the openings 72 on the front surface, and moved in and out by the frame-to-frame moving device 64 through the openings 73 on the back surface. When the replacement device 60 receives the storage rack 70, the frame-to-frame moving device 64 moves the replacement parts, supported on the multiple support rails 71 of the storage rack 70 and positioned at approximately the same height as the support rails 29 of the working device body 11, towards the working device body 11. Additionally, the frame-to-frame moving device 64 moves replacement parts supported on the support rails 29 of the working device body 11 into the support rails 71 of the storage rack 70, which are positioned at approximately the same height as those support rails 29. It should be noted that the receiving rack 70 can be transported to the receiving position of the changing device 60 by the operator, or it can be mounted on an automated guided vehicle (AGV) and automatically transported to the receiving position of the changing device 60 by the automated guided vehicle.

[0040] The conveying clamp 80 is a clamp used for moving the substrate support component 90 in and out, such as... Figure 6 and Figure 7 As shown, the device includes a rectangular frame 81 and a pair of arm members 82 that are fixed to the frame 81 with their front ends facing each other and hold the substrate support member 90 from both sides. In this embodiment, the transport clamp 80 has two sets of arm members 82 that hold the substrate support member 90, and is capable of transporting the substrate support member 90 used in the first and second substrate transport support devices 30 and 40 at one time.

[0041] like Figure 8 As shown, each arm component 82 includes: a base component 821, an arm plate 822, a retaining component 823, a side plate 825, a locking plate 826, and a locking block 827. It should be noted that, for ease of understanding of the structure, [details omitted]. Figure 8In the diagram, the side plate 825 and locking plate 826 near the front are shown in dashed lines. The base member 821 is fixed to the frame 81. The base end of the arm plate 822 is rotatably supported on the base member 821, and a retaining member 823 is rotatably mounted on the front 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 plates 825 is rotatably supported on the base member 821, and a retaining member 823 is rotatably mounted on the front end of the side plates 825. Furthermore, the side plates 825 exert an upward force on the arm plate 822 due to the force of a torsion coil spring 824 provided on the rotation axis of the base member 821. Additionally, the side plates 825 are positioned in a generally horizontal position by a stop formed on the base member 821, thus holding the arm plate 822 in a generally horizontal position. The retaining member 823 forms the front end of the arm member 82 and abuts against the short side portion of the bottom outer edge of the substrate support member 90 to hold the substrate support member 90. Thus, the substrate support member 90 is held from both sides by the front ends (retaining members 823) of the pair of arm members 82. The substrate support member 90, held by the pair of arm members 82, is pressed down and expanded above the worktables 36 and 46 by the arm plates 822 of the pair of arm members 82, thereby detaching from the transport clamp 80 and being placed on the worktables 36 and 46.

[0042] Locking plates 826 lock arm plates 822 in a way that prevents them from being pressed down. Locking plates 826 are disposed on both sides of arm plates 822, and a locking block 827 is fixed between the two locking plates 826, positioned below arm plates 822. The base end of the locking plate 826 is rotatably mounted in the base member 821 at an off-center position relative to the base end side of arm plates 822. The locking plates 826 are pulled towards arm plates 822 by the force of a tension spring 828 that engages with the locking plates 826 and arm plates 822 at a point closer to the top of the base end. The locking block 827 locks arm plates 822 in a way that prevents them from being pressed down by engaging with a cutout 822c formed on the lower surface of arm plates 822. Furthermore, the front ends of the two locking plates 826 protrude upwards from arm plates 822 while the locking block 827 is engaged with the cutout 822c of arm plates 822.

[0043] In this configured arm member 82, the arm plate 822 is locked in place by the locking block 827 engaging with the cutout 822c of the arm plate 822 due to the force of the pulling spring 828. Therefore, even if an unintentional force is applied to the substrate support member 90 or the arm plate 822, the arm member 822 will not be pressed down, preventing the substrate support member 90 from disengaging. The locking plate 826 can be released by pressing down the front end of the locking plate 826, which protrudes upwards from the arm plate 822.

[0044] The locking and unlocking of the locking plate 826 and the pressing down of the arm plate 822 are accomplished by a pusher 24. For example... Figure 9 and Figure 10 As shown, the pressing member 24 has a pair of front and rear pressing plates 241 respectively arranged on the left and right sides with a gap corresponding to the gap between the pair of arm members 82, and a pressing roller 242 arranged between each pair of front and rear pressing plates 241. If the pressing member 24 is lowered above the pair of arm members 82 by the pressing member lifting device 25, the lower ends of the pair of pressing plates 241 abut against the front ends of the locking plate 826, and the front ends of the locking plate 826 are pressed down by the pressing plates 241 (see reference). Figure 11 If the front end of the locking plate 826 is pressed down, the locking block 827 descends, and the engagement between the locking block 827 and the cutout 822c of the arm plate 822 is released (see reference). Figure 12 Thus, the locking of the arm plate 822 is released. If the pusher 24 descends further, the pusher roller 242 abuts against the arm plate 822, and the arm plate 822 is pressed down by the pusher roller 242 (see reference). Figure 13 As a result, the pair of arm members 82 are expanded, and the substrate support member 90 held in the pair of arm members 82 detaches from the arm members 82.

[0045] The control device 100 is configured as a CPU-centric microprocessor, and in addition to the CPU, it also includes ROM, RAM, input / output ports, etc. The control device 100 exchanges signals with the head unit 20, the first and second substrate transport support units 30 and 40, the camera unit 50, the changing unit 60, etc. Furthermore, the control device 100 is communicatively connected to the management device 200, which manages the entire operating system including the work unit 10. The management device 200 manages the progress of the production line including the work unit 10.

[0046] The operation of the working device 10 configured in this way will be explained. In particular, the operation of changing the screen mask M and the substrate support member 90 will be explained. The changeover adjustment is performed by sequentially performing mask removal, support member removal, support member insertion, and mask insertion with the housing 70 installed in the changeover device 60.

[0047] The mask removal process involves removing the wire mesh mask M supported on the support rail 29 of the working device body 11 and storing it in the receiving rack 70. In this mask removal process, the control device 100 controls the frame lifting device 63 to bring the free support rail 71 of the receiving rack 70 to approximately the same height as the support rail 29 of the working device body 11. Next, the control device 100 controls the head moving device 26 to push the wire mesh mask M supported on the support rail 29 forward from the working device body 11 by the pusher 24. Then, the control device 100 controls the frame moving device 64 to move the removed wire mesh mask M back and forth into the receiving rack 70. It should be noted that the mask loading process is essentially performed by the reverse action of the mask removal process, therefore its description is omitted.

[0048] The support component removal process is a process of using the conveyor clamp 80 to remove the substrate support component 90 from the worktables 36 and 46 of the main body of the working device 11 and to store it in the storage rack 70. The support component insertion process is a process of using the conveyor clamp 80 to insert the substrate support component 90 from the storage rack 70 and to place it on the worktables 36 and 46 of the main body of the working device 11. Figure 14 This is a flowchart illustrating an example of a support component loading process performed by the control device 100. It should be noted that the support component unloading process is essentially performed by the reverse action of the support component loading process, therefore its description is omitted.

[0049] In the support component loading process, the control device 100 first controls the transport jig 80, which holds the two substrate support components 90 to be replaced, to be transported above the worktables 36, 46 of the first and second substrate transport support components 30, 40 (step S100). Specifically, the control device 100 controls the frame lifting device 63 to raise the receiving rack 70 so that the support rail 71 supporting the transport jig 80 to be loaded next is at approximately the same height as the support rail 29 of the working device body 11. Next, the control device 100 controls the frame forward and backward movement device 64 to send the transport jig 80 out of the receiving rack 70 to the support rail 29. Then, the control device 100 lowers the pusher 24 using the pusher lifting device 25 and controls the head movement device 26 to push the transport jig 80 on the support rail 29 backward using the pusher 24 to load it in.

[0050] After the control device 100 moves the transport fixture 80 in, it controls the camera device 50 by reading the positioning mark 91 of the substrate support member 90 held in the transport fixture 80 after it has been moved in using the upper reading unit 52 of the camera body 51 (step S110). Then, based on the position of the read positioning mark 91, the control device 100 corrects the position of the transport fixture 80 so that the two substrate support members 90 held in the transport fixture 80 are directly above each of the worktables 36, 46 (step S120). That is, the control device 100 finely adjusts the position of the transport fixture 80 by pushing the transport fixture 80 forward or backward using the pusher 24 via the control head moving device 26.

[0051] Next, the control device 100 controls the support member lifting device 37 or 47 to raise the worktable 36 or 46 to the printing height (step S130). Next, the control device 100 controls the pusher lifting device 25 to lower the pusher 24 directly above the raised worktable (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 clamp 80 and placed on the worktable 36 or 46. As described above, if the pusher 24 lowers, the left and right pair of push plates 241 first abut against the locking plates 826 of the corresponding arm members 82, pressing them down, and the locking of the arm plates 822 is released. Furthermore, if the pusher 24 lowers further, the left and right pair of push rollers 242 abut against the corresponding arm plates 822, pressing them down, and the pair of arm members 82 are opened. Thus, the substrate support member 90 detaches from the pair of arm members 82 and is placed on the worktable. In this way, the substrate support member 90 can be detached from the transport fixture 80 and placed on the worktable by simply lowering the pusher 24 directly above the pair of arm members 82. Moreover, before placing the substrate support member 90 on the worktable, the control device 100 reads the positioning mark 91 using the camera device 50 and corrects the position of the substrate support member 90, thus more reliably suppressing positional displacement of the substrate support member 90 when it is placed on the worktable.

[0052] After the control device 100 places the substrate support member 90 onto the worktable 36 or 46, it controls the support member lifting device 37 or 47 to lower the worktable 36 or 46 to its initial position (step S160). It should be noted that the control device 100 uses the same control to place another substrate support member 90 held in the transport fixture 80 onto another worktable. Then, the control device 100 moves the transport fixture 80, after removing the two substrate support members 90, towards the receiving rack 70 (step S170), and the support member loading process is completed. That is, the control device 100 controls the head moving device 26 and the frame forward and backward moving device 64 to move the transport fixture 80, supported on the support rail 29, from the working device body 11 by the pusher 24 and into the receiving rack 70.

[0053] Here, the correspondence between the main elements of the embodiments and the main elements of the present disclosure as described in the claims will be explained. Specifically, the substrate support member 90 corresponds to the support member, the working device 10 corresponds to the working device, the conveying clamp 80 corresponds to the conveying clamp, and the pair of arm members 82 corresponds to the pair of arm members. Furthermore, the arm plate 822 corresponds to the arm member body, and the cutout 822c of the arm plate 822, the locking plate 826, the locking block 827, and the pull spring 828 correspond to the locking mechanism. Additionally, the locking plate 826 and the locking block 827 correspond to the locking piece, the pull spring 828 corresponds to the force-applying member, and the cutout 822c of the arm plate 822 corresponds to the engaged portion. Furthermore, the pushing member 24 corresponds to the pressing member, the pushing member lifting device 25 corresponds to the lifting device, and the control device 100 corresponds to the control device. Additionally, the pushing plate 241 corresponds to the first pressing portion, and the pushing roller 242 corresponds to the second pressing portion. Furthermore, the head moving device 26 corresponds to the moving device, and the camera device 50 corresponds to the position detection device.

[0054] It should be noted that this disclosure is not limited to the above-described embodiments. As long as it falls within the technical scope of this disclosure, it can be implemented in various ways, which is self-evident.

[0055] For example, in the above-described embodiment, the working device 10 has two channels for conveying and supporting the substrate S, but it may also have only one channel.

[0056] Furthermore, in the above embodiments, the working apparatus of this disclosure was described by applying it to a printing apparatus, but it is not limited thereto. As long as it is a working apparatus that performs work on a substrate supported on a support member, such as a component mounting apparatus, and can automatically replace the support member, it can also be applied to any working apparatus.

[0057] As explained above, the conveying fixture of this disclosure includes a pair of arm members. The pair of arm members are configured to rotate about mutually parallel rotating axes. Furthermore, the pair of arm members hold support members from both sides at predetermined rotational positions opposite each other at their front ends, and release the support members by pressing them down. Therefore, by moving the conveying fixture, with the support members held in the pair of arm members, upwards onto the worktable and pressing down the pair of arm members, the conveying fixture can be disengaged from the support members and placed on the worktable. As a result, the replacement of the support members becomes easy.

[0058] In such a conveying fixture of the present disclosure, the pair of arm components may each have: an arm component body capable of rotating about the rotation axis and holding the support component at the predetermined rotation position; and a locking mechanism that locks the arm component body at the predetermined rotation position. In this way, even if an unintentional force is applied to the support component or the arm component body, the holding of the support component can be prevented from being released.

[0059] Alternatively, in the conveying fixture disclosed herein, the locking mechanism may include: a locking plate capable of rotating independently relative to the arm component body; and a force-applying member that applies force to the locking plate in one direction of rotation. The locking plate engages with a locking portion formed on the arm component body through the force of the force-applying member, thereby locking the arm component body. The locking plate is then pressed down in the other direction of rotation to release the engagement of the locking plate, thereby releasing the locking of the arm component body. In this way, by pressing down, the locking plate can be pressed down to release the locking plate from the arm component body, and the arm component body can be pressed down to release the arm component body from holding the support member.

[0060] The disclosed working device enables the replacement of support components using a conveyor clamp, and includes a pressing component, a lifting component, and a control device. With the conveyor clamp positioned above the worktable, the control device controls the lifting device to lower the pressing component, thereby pressing down a pair of arm components and placing the support components on the worktable. Thus, the support components can be automatically replaced through simple control.

[0061] In such a working device of the present disclosure, the pair of arm components may each have: an arm component body capable of rotating about the rotation axis and holding the support member at the predetermined rotation position; and a locking mechanism that locks the arm component body at the predetermined rotation position. The locking mechanism has: a locking plate capable of rotating independently relative to the arm component body; and a force-applying member that applies force to the locking plate to one side in the rotation direction. The locking plate engages with the engaging portion formed in the arm component body by the force of the force-applying member, thereby locking the arm component body. The locking plate is pressed down to the other side in the rotation direction to release the engagement of the locking plate, thereby releasing the locking of the arm component body. The pressing member has a first pressing portion that presses down the locking plate and a second pressing portion that presses down the arm component body. It is lowered by the lifting device, thereby pressing down the locking plate with the first pressing portion. It is further lowered by the lifting device, thereby pressing down the arm component body with the second pressing portion. In this way, by pressing down the pressing component, the locking plate can be pressed down to release the locking plate from the main body of the arm component, and the main body of the arm component can be pressed down to release the main body of the arm component from the support component.

[0062] Furthermore, the operating apparatus disclosed herein may include: a moving device for moving the worktable relative to the conveyor fixture; and a position detection device for detecting the position of the support member. The control device, based on the position of the support member detected by the position detection device when the conveyor fixture holding the support member is moved in, controls the moving device to align the support member and the worktable, and then controls the lifting device to lower the pressing member to place the support member on the worktable. This reliably suppresses positional deviation of the support member placed on the worktable. It should be noted that the moving device can move either the conveyor fixture or the worktable.
