Description

[Technical Field]

[0001] The present disclosure relates to an observation device for observing an observation object such as a component mounted on a board. [Background technology]

[0002] The manufacture of mounted boards uses a component mounting system that mounts electronic components (hereinafter simply referred to as "components") on the board. In the component mounting system, a component mounting operation is performed in which a mounting head picks up components from a component supply unit and mounts them on the board. In the component mounting operation, to prevent component mounting errors, a camera captures an image of the components held by the mounting head before mounting, and the captured image is compared with component recognition data for recognition.

[0003] Component recognition data is teaching data for accurately recognizing components from acquired images, and includes various information such as the component's outer diameter, color, lead shape, number, and pitch. One proposed method for creating component recognition data is to use a component mounting system that includes a host device functioning as a management computer, a production line controlled by the host device for mounting components onto a board, and an offline camera unit that is separate from the production line and connected to the host device. The component recognition data is then generated by capturing images of components using a camera installed in the offline camera unit and transmitting the captured images to the host device for recognition (see, for example, Patent Document 1). According to the example in Patent Document 1, the images required for creating the component recognition data are captured not by an online camera unit installed on the production line, but by an offline camera unit installed outside the production line. This allows components to be captured and component recognition data to be generated without temporarily stopping the production line. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-144167 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, if the observation targets of offline camera units could be expanded beyond board-mounted components, the efficiency of various tasks could be improved. In other words, if imaging tasks that could previously only be performed using camera units on the production line could be performed with offline camera units, it would be possible to observe objects regardless of the operating status of the production line. However, conventional offline camera units are designed only for imaging or observing components for the purpose of creating component data. Therefore, in order to observe objects other than components, it was necessary to reconsider the configuration of the stage on which the observation target is placed.

[0006] Therefore, an object of the present disclosure is to provide an observation device that is highly versatile by expanding the range of objects to be observed. [Means for solving the problem]

[0007] The observation device disclosed herein is an observation device for observing an object to be observed, and includes a tray on which the object to be observed is placed and a tray holding means for detachably attaching the tray, and multiple types of trays are prepared for different uses. [Effects of the Invention]

[0008] According to the present disclosure, a plurality of trays on which objects to be observed are placed can be prepared according to the application, and these can be detachably attached to the stage, thereby providing an observation device with excellent versatility.

DETAILED DESCRIPTION OF THE INVENTION

[0010] (Embodiment 1) Next, a first embodiment of the present disclosure will be described with reference to the drawings. First, with reference to FIG. 1, a component mounting system 1 that manufactures a mounted board by mounting components on a board will be described. FIG. 1 is an overall configuration diagram of a component mounting system in which an observation device according to the first embodiment of the present disclosure is disposed. The component mounting system 1 mainly includes a production line that connects electronic component mounting devices, namely a printing device M1, a board transfer device M2, an inspection and mounting device M3, component mounting devices M4 and M5, an inspection and mounting device M6, a board transfer device M7, and a reflow device M8, in the board transport direction (direction of arrow X) in which a board 4 to be processed is transported. The devices that make up the component mounting system 1 (printing device M1 to reflow device M8) are connected via a communication network 2 and controlled by a host device 3 that functions as a management computer.

[0011] The printing device M1 prints solder onto the electrodes of the board 4. The board transfer device M2 receives the board 4 from the printing device M1 and passes it on to the downstream inspection and mounting device M3. The inspection and mounting device M3 inspects the solder printed on the board 4 and mounts components 200 onto the board 4. The component mounting devices M4 and M5 mount the components 200 onto the board 4 sent from the inspection and mounting device M3. The inspection and mounting device M6 inspects the mounting state of the components mounted on the board 4 and mounts the components 200 onto the board 4. The board transfer device M7 receives the board from the inspection and mounting device M6 and passes it on to the downstream reflow device M8. The reflow device heats and melts the solder on the board 4 to solder-bond the board 4 and the components 200.

[0012] The host device 3 creates component recognition data that is referenced, for example, when component mounting devices M4 and M5 mount components 200 on a board 4, or when an inspection and mounting device M6 inspects the components 200 mounted on a board. An offline camera unit 5 is connected to the host device 3 via a communication network 2 as an observation device (camera device) that is arranged off the production line.

[0013] The offline camera unit 5 performs observations of the components 200 necessary for creating component recognition data, observations of the components 200 housed in a carrier tape (described later), and observations of the suction nozzles used in the component mounting devices M4 and M5. In this specification, "observation" includes capturing images of the components 200 and other objects to be observed. Images acquired by the offline camera unit 5 are sent to the host device 3. The components mounting system 1 is made up of each device (printing device M1 to reflow device M8), the host device 3, and the offline camera unit 5. In other words, the offline camera unit (observation device) 5 observes the objects to be observed used in the component mounting devices M4 and M5.

[0014] Next, the offline camera unit 5 will be described with reference to Fig. 2. Fig. 2 is a perspective view of the offline camera unit according to the first embodiment of the present disclosure. The offline camera unit 5 is connected to the host device 3 via a communication network 2, either wired or wirelessly, and includes a cover 5a, a camera 300, a base 5b, and an observation stage 10.

[0015] The cover 5a is provided to surround the upper side of the offline camera unit 5, and the camera 300 is disposed inside the cover 5a. The camera 300 is disposed so that the imaging direction faces downward. The offline camera unit 5 is also equipped with an observation light (not shown) that emits illumination light downward. The imaging operation and illumination light emission operation of the camera 300 are controlled by the host device 3. The base part 5b is disposed in the front-opening portion below the cover 5a, i.e., below the camera 300, and an observation stage 10, which will be described in detail later, is disposed on the base part 5b.

[0016] Next, the observation stage 10 will be described with reference to FIGS. 3 to 9. FIG. 3 is a perspective view of the observation stage included in the offline camera unit according to the first embodiment of the present disclosure. FIG. 4 is a plan view of the observation stage included in the offline camera unit according to the first embodiment of the present disclosure. FIG. 5 is a plan view of the observation stage included in the offline camera unit according to the first embodiment of the present disclosure with the tray removed. FIG. 6 is a perspective view of a guide member in the offline camera unit according to the first embodiment of the present disclosure. FIG. 7 is a perspective view of a pressing member in the offline camera unit according to the first embodiment of the present disclosure. FIG. 8 is a perspective view of the observation stage included in the offline camera unit according to the first embodiment of the present disclosure. FIG. 9 is a side view of the observation stage included in the offline camera unit according to the first embodiment of the present disclosure. The observation stage 10 includes a tray 20, a table 30, and a lifting mechanism 90.

[0017] The tray 20, on which an observation object to be imaged by the camera 300 is placed, comprises a tray body 21, a frame 22, and a metal member 23. The tray body 21 is formed from a rectangular plate-like member made of transparent or translucent plastic or glass, and has dividing lines 21a extending in the width direction (indicated by arrows X1-X2) and the depth direction (indicated by arrows Y1-Y2) to indicate the position where the observation object is to be placed. The upper surface of the tray body 21 serves as a placement surface on which the observation object is to be placed. This placement surface is an infrared-transmitting filter made of resin, and the camera 300 recognizes the position where the observation object is to be placed from an image of light transmitted through this infrared-transmitting filter. The dividing lines 21a may also be used to allow the camera 300 to automatically recognize the position where the observation object is to be placed.

[0018] The frame 22 is provided to surround three sides of the tray body 21 and comprises a rear frame portion 22a, a right frame portion 22b, and a left frame portion 22c. The rear frame portion 22a is provided along the rear edge portion (the edge portion on the arrow Y2 side) of the tray body 21, and a finger hole 22e is formed in a tab 22d that protrudes from the center. The right frame portion 22b and the left frame portion 22c extend from both ends of the rear frame portion 22a along the right edge portion (the edge portion on the arrow X2 side) and the left edge portion (the edge portion on the arrow X1 side) of the tray body 21, respectively.

[0019] The metal member 23 protrudes from the front edge (the edge on the arrow Y2 side) on the lower surface side of the tray main body 21, and is provided so that its upper surface is at a height position lower than the upper surface of the tray main body 21. The metal member 23 is made of a material that is attracted by a magnetic member (magnet) 70, which will be described later. In addition, notches 23a (FIG. 4) are formed on both sides of the end surface of the metal member 23 in the width direction.

[0020] The table 30, to which the tray 20 is detachably attached, comprises an upper table 40 and a lower table 80. The upper table 40 is formed in the shape of a rectangular plate having a larger area than the tray 20, and has an opening 41 formed across the entire width at approximately the center in the depth direction (the direction of arrows Y1-Y2) through which illumination light emitted from an observation illumination 83 (FIG. 5), which will be described in detail later, passes. In addition, on the top surface of the upper table 40, a pair of guide members 50, a pressing member 60, and a magnetic member 70 are arranged as tray holding means for detachably attaching the tray 20.

[0021] The pair of guide members 50 guides the tray 20 so that it is positioned at a predetermined position on the upper table 40. The pair of guide members 50 are disposed opposite each other on both sides of the width direction of the upper table 40, and include a tray support portion 51 and an inclination adjustment mechanism 52, as shown in FIG.

[0022] 6, the tray support portion 51 includes a support surface 51a that supports the underside of the right frame portion 22b or the left frame portion 22c of the frame 22 of the tray 20, and an abutment portion 51b provided on the support surface 51a. When the tray 20 is advanced in the depth direction (the Y1-Y2 direction shown in FIGS. 3 to 5), the abutment portion 51b abuts against the right frame portion 22b or the left frame portion 22c of the frame 22, thereby guiding the tray 20 along the depth direction. A plurality of holes 51c are formed in the support surface 51a and the abutment portion 51b, penetrating both. Screws (not shown) protruding from the upper table 40 are inserted into the holes 51c, allowing the tray support portion 51 to move up and down. In addition, bolt holes 51d are formed on the side surfaces of the abutment portions 51b.

[0023] The tilt adjustment mechanisms 52 are provided at two locations on the outside of each tray support portion 51 and are fixed onto the upper table 40. In addition, bolt holes 52a that communicate with bolt holes 51d in the adjacent abutment portion 51b are formed on the outer surface of the tilt adjustment mechanism 52. Bolts 52b are threaded into the bolt holes 51d and 52a, and by tightening the bolts 52b, the tray support portion 51 can be fixed so that it does not move up and down.

[0024] When it is confirmed that the tray 20 is mounted at an angle relative to the upper table 40, the tilt adjustment mechanism 52 configured in this manner can adjust the flatness of the tray 20 by gradually moving the tray support part 51 up and down (in the direction of the arrow Z) while checking the state of the tray 20, and then tightening and fixing the bolt 52b at a height position where the tray 20 is straight.

[0025] 3, 4, etc., the pressing member 60 is positioned opposite the imaging surface of the camera 300 and restricts the upward movement (arrow Z direction) of the front end side (arrow Y2 side) of the tray 20, which is guided by a pair of guide members 50 and attached to the upper table 40. As shown in FIG. 7, the pressing member 60 is formed in a rectangular plate shape, and holes (not shown) are formed on both sides of the width direction thereof. Furthermore, a base 61 is interposed between these holes and the upper table 40. The base 61 is made of a cylindrical member formed slightly higher than the height of the upper surface of the metal member 23 provided on the tray 20. Meanwhile, the upper table 40 is formed with bolt holes (not shown) that communicate with the inside of the base 61.

[0026] The retaining member 60 is fixed by inserting a bolt 62 through a hole in the retaining member 60 and into the inside of the base portion 61, and screwing it into a bolt hole in the upper table 40. This makes it possible to prevent contact with the camera 300 when the tray 20 tries to move upward toward the camera 300 by contacting the retaining member 60.

[0027] The magnetic members 70 are provided on both sides of the retaining member 60 and include magnets that are attracted to the end surfaces of the metal members 23 provided on the tray 20 attached to the upper table 40. By attracting the metal members 23 of the tray 20 to the magnetic members 70, the tray 20 is removably fixed in the depth direction. On the other hand, if the contact surface between the magnets of the magnetic member 70 and the metal members 23 is wide, the magnets and the metal members 23 may be attracted too strongly, potentially making it difficult to remove the tray 20. Therefore, by attracting the magnets to the positions of the notches 23a (see FIG. 7, etc.) in the metal members 23, the contact surface with the magnets is reduced, allowing the tray 20 to be fixed with an appropriate level of attraction that does not interfere with removal. While a single magnetic member 70 may be provided, it is preferable to provide one magnetic member 70 on each side of the retaining member 60.

[0028] The tray 20 is attached to the upper table 40 configured in this manner. As shown in Fig. 8, the tray 20 can be attached by gripping the tray body 21 using the finger holes 22e, and moving the tray body 21 forward (in the direction of arrow Y2) while bringing both sides of the tray body 21 into contact with the guide members 50, and positioning the metal member 23 below the pressing member 60. Conversely, the tray 20 can be removed by pulling it out toward the front (in the direction of arrow Y1 shown in Fig. 3) using the finger holes 22e.

[0029] The lower table 80 is disposed below the upper table 40. As shown in FIGS. 3 and 5, the lower table 80 is formed in the shape of a rectangular plate with approximately the same dimensions and shape as the upper table 40. Approximately in the center of the lower table 80, there is provided a slot 81 for passing illumination light from an observation illumination device 83 (described in detail below), and a translucent cover 82 for closing the slot 81 and transmitting the illumination light. The translucent cover 82 is a diffusion plate made of resin and has the function of diffusing and uniforming the light. The upper table 40 and the lower table 80 are connected by a slide mechanism (not shown) that moves the upper table 40 relative to the lower table 80 in the width and depth directions. This allows the position of the observation object placed on the tray 20 to be adjusted relative to the imaging surface without moving it.

[0030] An observation illuminator 83 consisting of multiple LED elements is disposed on the underside of the lower table 80. The observation illuminator 83 is fixed so as to be exposed from the elongated hole 81, and the illumination light emitted from it passes through the elongated hole 81, the semi-transparent cover 82, and the opening 41 in the upper table 40, and reaches the upper surface of the tray body 21 of the tray 20 attached to the upper table 40. Note that the observation illuminator 83 is always exposed from the elongated hole 81 and the opening 41, and can irradiate the illumination light onto the object to be observed even when the upper table 40 is moved by the slide mechanism.

[0031] 9, the lifting mechanism 90 adjusts the table 30, which includes the upper table 40 and the lower table 80, to any height position, and includes a base plate 91, a lifting actuator 92, and an operation unit 93. The lifting actuator 92 and the operation unit 93, which will be described in detail later, are disposed on the upper surface of the base plate 91, and the base plate 91 is fixed to the base 5b of the offline camera unit 5.

[0032] The lifting operation unit 92 is formed by a first link member 92a and a second link member 92b formed in the shape of an elongated plate, each rotatably fixed by a pivot 92c at approximately the center thereof, and the first and second link members 92a and 92b are disposed below the table 30 on both sides in the width direction. The first link member 92a has an upper end rotatably fixed to a rear bracket 84a provided on the rear side (arrow Y2 side) of the underside of the lower table 80, and a lower end provided on the front side (arrow Y1 side) of the base plate 91, and is rotatably fixed via a small link 92d to an operating unit 94, which will be described in detail later. The second link member 92b has an upper end rotatably fixed to a front bracket 84b attached to a slide rail 85 provided on the front side of the underside of the lower table 80 and slidable in the depth direction, and a lower end rotatably fixed to a rear bracket 91a provided on the rear side of the base plate 91.

[0033] The operating unit 93 operates the lifting / lowering operating unit 92 and includes an acting unit 94 and a handle 95. The acting unit 94 is slidably disposed on a slide rail 96 that extends in the depth direction (the direction of the arrows Y1-Y2) on the front side of the base plate 91, and the lower ends of second link members 92b that constitute the lifting / lowering operating unit 92 are rotatably fixed to both ends in the width direction via small links 92d.

[0034] The handle 95 is disposed on the front side of the slide rail 96, and has a knob 95a on the front surface to assist in rotation operation. One end of a screw 95b is fixed to the back surface of the handle 95, and the screw 95b rotates in conjunction with the rotation of the handle 95. The screw 95b is a trapezoidal screw with a trapezoidal thread, and one end thereof fixed to the handle 95 is supported by a handle support portion 95c fixed to the base plate 91, and the other end thereof is threaded into a screw hole (not shown) formed in the action portion 94.

[0035] When the operator rotates the handle 95, the threads of the screw 95b move along the thread groove of the screw hole in the action part 94, and accordingly, the action part 94 is guided by the slide rail 96 and slid in the depth direction. In conjunction with this, the first link member 92a connected to the action part 94 operates, and the second link member 92b slides the front bracket 84b, to which the upper end is fixed, along the slide rail 85, and the first link member 92a and the second link member 92b rotate about the pivot 92c, operating the lifting operation part 92 and moving the table 30 up and down.

[0036] In this way, the lifting mechanism 90 allows the height position of the table 30 to be adjusted by rotating the handle 95. Note that the opening angles of the first link member 92a and the second link member 92b between the lifting actuators 92 on both sides may not be uniform, which may cause a slight tilt in the tray 20. In this case, the flatness of the tray 20 can be corrected by operating the tilt adjustment mechanism 52 described above.

[0037] As described above, the offline camera unit (observation device) 5 of the first embodiment observes an observation target (a component 200 in the first embodiment) used in the component mounting devices M4, M5, etc. The offline camera unit 5 includes a tray 20 on which the observation target is placed. The tray 20 in the first embodiment is a first tray having a metal member 23 at its front end and a placement surface on which the component 200 as the observation target is placed. Guide members 50 that guide both sides of the tray 20, a pressing member 60 that contacts the upper surface of the tray 20 near its front end when the tray 20 is positioned at a predetermined position by the guide members 50, and one or more magnetic members 70 that attract the metal member 23 form a tray holding means for detachably mounting the tray 20. The offline camera unit 5 also includes an inclination adjustment mechanism 52 that adjusts the inclination of the mounted tray 20.

[0038] The tray 20 can be detachably attached by attracting and holding the metal member 23 on the tray 20 to the magnetic members 70 provided on both sides of the retaining member 60. This allows for the use of multiple types of trays 20, each prepared for a different type of observation object or purpose, by interchangeably selecting the appropriate tray. This enables the observation of a variety of objects with a single offline camera unit 5. Furthermore, the guide member 50 provided on the upper table 40 of the table 30 allows the tray 20 to be positioned in a predetermined position, the retaining member 60 prevents the tray 20 from moving upward, and the tilt adjustment mechanism 52 adjusts the flatness of the tray 20, allowing the tray 20 to be stably attached. Furthermore, the height of the table 30 can be adjusted by the lifting mechanism 90, allowing the optimum distance between the observation object and the imaging plane of the camera 300 of the offline camera unit 5 to be set.

[0039] (Embodiment 2) The observation stage 10 in the second embodiment of the present disclosure has the same configuration as the observation stage 10 in the first embodiment except for the tray 20A. Therefore, the tray 20A shown in Fig. 10 will be described in detail here, and the description of the other configurations will be omitted. The objects to be observed in the embodiment are the carrier tape T and the components 200 accommodated in the carrier tape T.

[0040] When components 200 to be mounted on board 4 have irregular shapes (e.g., approximately L-shaped in plan view), it may be necessary to set the position at which the nozzle picks up the components 200 each time. Tray 20A in the second embodiment is configured such that, when setting the nozzle pick-up position for components 200, offline camera unit 5 captures an image of components 200 housed in a carrier tape, and positional information regarding the placement of components 200 can be acquired from the captured image. As shown in FIG. 10 , tray 20A includes tray body 21 and carrier tape holding section 100. Tray body 21 is a rectangular plate-like member attached to upper table 40 of table 30. Tray body 21 is provided with metal member 23 at the front edge (edge ​​on the Y2 side) of the underside, and two finger holes 22e at the rear edge (edge ​​on the Y1 side).

[0041] 10 is a perspective view of a tray included in an offline camera unit according to a second embodiment of the present disclosure. FIG. 11 is a perspective view of a tray included in an offline camera unit according to a third embodiment of the present disclosure. As shown in FIGS. 10 and 11 , carrier tape holding unit 100 secures carrier tape T, on both sides thereof, on which components 200 are accommodated, and includes first support member 111, first pressing member 112, second support member 121, and second pressing member 122. Carrier tape T is a tape-like packaging material that accommodates, transports, and stores components 200. Carrier tape T has a plurality of pockets P arranged in series along its longitudinal direction, each of which accommodates one component 200. On one or both sides of the plurality of consecutive pockets P, a plurality of sprocket holes H are formed. These sprockets engage with sprockets for feeding carrier tape T provided in tape feeders set in component mounting devices M4 and M5 in component mounting system 1.

[0042] The first support member 111 is a flat member erected from the tray body 21 of the tray 20, and below it is formed a relief portion 111a to prevent interference with a slide rail 124, which will be described in detail later. The top surface of the first support member 111 is provided with a pin member 111b that serves as a marker when determining the fixing position of the carrier tape T, and the side surface is provided with a screw hole (not shown) into which a fixing screw 113, which will be described in detail later, is screwed.

[0043] The first pressing member 112 fixes one side of the carrier tape T between itself and the upper surface of the first support member 111. The first pressing member 112 includes a pressing piece 112a formed to face the upper surface of the first support member 111, a fixing portion 112b bent downward at approximately 90° from the pressing piece 112a and extending along the side surface of the first support member 111, and an operation piece 112c bent approximately 90° and extending laterally from the fixing portion 112b. A vertically elongated hole (not shown) is formed in the fixing portion 112b, through which a fixing screw 113 (not shown) is inserted, which is threaded into a screw hole in the first support member 111. When the fixing screw 113 is tightened, the fixing portion 112b is pressed against the side surface of the first support member 111 and fixed.

[0044] The second support member 121 is a flat plate-like member erected from the upper surface of the tray main body 21, and is attached to a slide rail 124 extending in the width direction of the tray 20 (the direction of the arrow X), and is provided so as to be movable via the slide rail 124 in directions toward and away from the first support member 111 (the X1-X2 directions in FIG. 11). A screw hole (not shown) is provided on the side surface of the second support member 121, into which a fixing screw 123 for fixing a second tape pressing member 122, which will be described in detail later, is screwed.

[0045] The second support member 121 is further provided with a slide restriction portion 125 that is fixed to the tray main body 21. The slide restriction portion 125 includes a flat portion 125a that extends horizontally from below the side surface of the second support member 121, and a fixing screw 125b that is screwed into a screw hole (not shown) that is provided in the flat portion 125a. The second support member 121 is fixed by sliding it along the slide rail 124 to a desired position and then tightening the fixing screw 123 until the tip of the threaded portion (not shown) of the fixing screw 123 abuts against the upper surface of the tray main body 21.

[0046] The second pressing member 122 fixes the other side of the carrier tape T (the side opposite to the side fixed to the first support member 111) between the second pressing member 122 and the upper surface of the second support member 121. The second pressing member 122 includes a pressing piece 122a provided opposite the upper surface of the first support member 111, a fixing portion 122b bent downward from the pressing piece 122a by approximately 90 degrees and extending along the side surface of the second support member 121, and an operation piece 122c bent approximately 90 degrees and extending outward from the fixing portion 122b. A vertically long hole (not shown) is formed in the fixing portion 122b, through which a fixing screw 123 is inserted, which is threaded into a screw hole in the second support member 121. When the fixing screw 123 is tightened, the fixing portion 122b is pressed against the side surface of the second support member 121 and fixed.

[0047] The carrier tape T can be fixed to the carrier tape holding unit 100 configured as described above as follows. First, the carrier tape T is placed on the top surface of the first support member 111 while inserting the pin member 111b into one of the sprocket holes H (FIG. 10) that is in a specific positional relationship with the pocket P. Then, the first pressing member 112 is moved by holding the operation piece 112c, and the fixing screw 113 is tightened with the pressing piece 112a pressing the carrier tape T, thereby fixing one side of the carrier tape T. Next, the second support member 121 is slid to a position where the other side of the carrier tape T can be placed, and the fixing screw 125b of the slide restriction unit 125 is tightened to fix the carrier tape T to the tray main body 21. Then, the other side of the carrier tape T is placed on the upper surface of the second support member 121, and then the second pressing member 112 is moved by holding the operating piece 122c, and the fixing screw 123 is tightened while the pressing piece 122a is pressing the carrier tape T, and the other side of the carrier tape T is fixed, thereby completing the fixing of the carrier tape T.

[0048] As described above, tray 20A (second tray) includes carrier tape holding section 100 that holds carrier tape T containing components 200 as objects to be observed, and carrier tape T is fixed by carrier tape holding section 100. Therefore, components 200 contained in pockets P can be set in offline camera unit 5 and observed (imaged). This allows positional information regarding the arrangement of components 200 contained in pockets P to be acquired outside the production line.

[0049] (Embodiment 3) The observation stage 10 in the third embodiment of the present disclosure has the same configuration as the observation stage 10 in the first embodiment except for the tray 20B. Therefore, the tray 20B will be described in detail here, and the other configurations will not be described. The observation target in the third embodiment is the nozzle N or the component 200 held by suction on the nozzle N. The nozzle N is used in component mounting devices M4, M5, etc. to hold the component 200 by suction. The nozzle N is composed of a base N1, a flange N3, and a tube N2 connected in this order. An air flow path is formed inside the nozzle N, and an opening communicating with the air flow path is formed at the tip of the tube N2.

[0050] The tray 20B allows the nozzle to be placed on the observation stage 10 when observing the appearance of the nozzle used to suck and hold the component 200 in the component mounting system 1 shown in FIG. 1 for purposes such as checking the shape before mounting on the mounting head, checking for dust after cleaning, or checking the state of the component 200 after suction. As shown in FIG. 12, the tray 20B includes a tray main body 21 and a nozzle holder 24 that holds the nozzle N. FIG. 12 is a perspective view of a tray included in the offline camera unit (observation device) according to the third embodiment of the present disclosure. The tray main body 21 is made of a rectangular plate-like member that is attached to the upper table 40. A metal member 23 protrudes from the front edge (the edge on the arrow Y2 side) of the underside, and two finger holes 22e are provided near the rear edge (the edge on the arrow Y1 side).

[0051] The nozzle holding part 24 includes a holder 25 and a pump connection part 26, and is disposed on the tray main body 21. The holder 25 is formed with a nozzle insertion hole 25a through which the base N1 of the nozzle N is inserted, and by bringing the flange N3 into contact with the upper surface of the holder 25 during the process of inserting the base N1 into the nozzle insertion hole 25a, the nozzle N is held in an upright state with the opening of the tube part N2 facing upward. Note that the tube part N2 of the nozzle N may be inserted into the nozzle insertion hole 25a.

[0052] Pump connection part 26 is disposed below holder 25 and is rotatable in the width direction (direction of arrow X). One end of pump connection part 26 is connected to base part N1 exposed on the underside of holder 25, and the other end is formed with connection port 26a to which a hose of a suction pump (not shown) is connected. When nozzle N is set in holder 25 and the suction pump connected to connection port 26a is operated, the air flow path of nozzle N is suctioned by vacuum, and component 200 can be sucked and held via the opening of tube part N2.

[0053] In this way, tray 20B (third tray) has nozzle holder 24 that holds nozzles onto which components 200 are sucked and held. By using tray 20B, it is possible to check the shape of nozzle N before it is attached to the mounting heads of component mounting devices M4 and M5, check for the presence or absence of dust after cleaning, and check the state of component 200 sucked onto nozzle N. Note that, depending on the purpose of observing nozzle N, it is not essential to connect a suction pump to pump connector 26.

[0054] As described above, the offline camera unit (observation device) 5 disclosed in this specification is provided with a plurality of types of trays (20, 20A, 20B) for different uses, which makes it possible to widen the range of objects to be observed (imaged) by the offline camera unit 5. As a result, it is possible to provide an offline camera unit 5 with excellent versatility.

[0055] The present disclosure is not limited to the above-described embodiments, and various modifications and combinations are possible within the scope of the claims and the embodiments, and these modifications and combinations are also included in the scope of the rights. For example, the trays 20, 20A, and 20B shown in the above-described first to third embodiments can be configured for a different purpose, and the tilt adjustment mechanism 52 and the lifting mechanism 90 of the upper table 40 in the table 30 can be omitted. [Industrial Applicability]

[0056] According to the present disclosure, an offline camera unit (observation device) 5 placed outside the production line can observe various observation targets other than the component 200. In other words, by expanding the range of observation targets, it is possible to provide an observation device with excellent versatility, which is useful in the field of component mounting.
