Description
[Technical Field]
[0001] This invention relates to a feeder setup operation that adjusts the position of a component storage tape in a feeder that supplies components to a component supply position by transporting the component storage tape that stores components in the component storage tape in a transport direction, thereby adjusting the positional relationship between the components in the component storage tape and the component supply position. [Background technology]
[0002] In a component mounter that mounts components on a board, components are supplied using a component storage tape that stores components in multiple pockets arranged at a predetermined pitch. Specifically, as described in Patent Documents 1 to 3, the component storage tape is pulled out from a component supply reel and conveyed by a feeder, and the components stored on the component storage tape are supplied to a component supply position. In particular, Patent Documents 1 and 2 propose technologies to assist an operator in performing feeder setup work, which involves sending the leading end of a component storage tape set in a feeder to a component supply position. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] WO2020 / 065752 [Patent Document 2] Japanese Patent Application Laid-Open No. 2014-241344 [Patent Document 3] WO2020 / 065752 Summary of the Invention [Problem to be solved by the invention]
[0004] This type of feeder setup work is performed, for example, by feeding a component storage tape set in a feeder to position the leading component on the component storage tape at the component supply position, and then moving the component storage tape back by one pitch. Therefore, workers must visually confirm that the component has been fed to the component supply position. Therefore, there was a need for technology to assist workers in their work, allowing them to easily and accurately check the component supply position of the feeder.
[0005] The present invention has been made in consideration of the above-mentioned problems, and has an object to provide a technique for assisting a worker in his / her work so that the worker can easily and accurately check the component supply position of a feeder. [Means for solving the problem]
[0006] The feeder setup work support device of the present invention is a feeder setup work support device that supports feeder setup work by adjusting the position of a component storage tape in a feeder that supplies components to a component supply position by transporting the component storage tape in a transport direction, thereby adjusting the positional relationship between the components in the component storage tape and the component supply position.The device is equipped with a feeder mounting unit to which the feeder is detachably mounted, and an imaging display unit that uses a camera to capture an image including the component supply position of the feeder mounted to the feeder mounting unit and displays it on a screen, and the imaging display unit adjusts the range to be displayed on the screen based on display target information related to the component supply position that is the display target.
[0007] The feeder setup work support method of the present invention supports feeder setup work by adjusting the position of a component storage tape in a feeder that supplies components to a component supply position by transporting the component storage tape in a transport direction, thereby adjusting the positional relationship between the components in the component storage tape and the component supply position.The method includes the steps of: capturing an image including the component supply position of a feeder attached to a feeder attachment section using a camera; and capturing the image including the component supply position using the camera and displaying it on a screen, and the range displayed on the screen is adjusted based on display target information related to the component supply position that is the display target.
[0008] In the present invention (feeder setup work support device, feeder setup work support method) configured as described above, an image including the component supply position is captured by a camera and displayed on a screen. Therefore, a worker can visually check the component supply position by looking at this screen. However, if the range displayed on the screen is not appropriate for the component supply position, for example, part of the component supply position may extend outside the screen, or the range showing the component supply position on the screen may be too narrow. Therefore, the present invention adjusts the range displayed on the screen based on display target information related to the component supply position to be displayed. This makes it possible to display an appropriate range for the component supply position on the screen. In this way, it is possible to support the worker's work by allowing the worker to easily and accurately check the component supply position of the feeder.
[0009] The feeder setup work support device may also be configured so that the display target information includes feeder width information indicating the width of the feeder, and the imaging and display unit adjusts the range to be displayed on the screen based on the feeder width indicated by the feeder width information. In other words, the range to be displayed on the screen changes because the component supply position of the feeder differs depending on the feeder width. Therefore, by configuring as described above, it is possible to display on the screen an appropriate range for the component supply position for each of multiple types of feeders with different widths.
[0010] The feeder setup work support device may also be configured so that the feeder has a memory unit that stores feeder width information, and the imaging and display unit acquires the feeder width information by reading the feeder width information from the memory unit of the feeder attached to the feeder attachment unit. In this configuration, the width of the feeder attached to the feeder attachment unit for feeder setup work can be accurately acquired, and an appropriate range for the component supply position of this feeder can be displayed on the screen.
[0011] The feeder setup work support device may be configured so that the feeder has a tape guide that guides the component storage tape to the component supply position, and the imaging display unit acquires feeder width information by extracting the width of the tape guide shown by the image of the tape guide captured by the camera as the width of the feeder. With this configuration, the feeder width can be reliably acquired even in situations where the feeder width information has not been prepared in advance.
[0012] The feeder setup operation support device may also be configured so that the display target information includes component size information indicating the size of the component to be supplied to the component supply position, and the imaging and display unit adjusts the range displayed on the screen based on the component size indicated by the component size information. In this configuration, the range displayed on the screen is adjusted according to the size of the component to be supplied to the component supply position. This makes it possible to support the worker's work by allowing the worker to easily and accurately check the component supply position of the feeder.
[0013] The feeder setup operation support device may further include a reading unit that reads component IDs attached to component supply reels that hold component storage tapes and that identify the components stored on the component storage tapes, and the imaging and display unit acquires component size information included in the component IDs read by the reading unit. With this configuration, the size of the components to be supplied to the component supply positions by the feeders that are the targets of the feeder setup operation can be accurately acquired, and an appropriate range for the components to be supplied to the component supply positions of the feeders can be displayed on the screen.
[0014] The feeder setup operation support device may also be configured so that the display target information includes tape width information indicating the width of the component storage tape, and the imaging and display unit adjusts the display range on the screen based on the width of the component storage tape indicated by the tape width information. In other words, the width of the feeder used to transport the component storage tape may vary depending on the width of the component storage tape. Meanwhile, the component supply position of the feeder differs depending on the width of the feeder, and therefore the display range on the screen changes. Therefore, by configuring as described above, it is possible to display an appropriate range for the component supply position on the screen while dealing with differences in feeder width depending on the width of the component storage tape.
[0015] The feeder setup operation support device may be configured so that the imaging and display unit adjusts the range displayed on the screen by changing the magnification at which the camera captures the component supply position. In this configuration, an image of the component supply position captured at an appropriate magnification can be displayed on the screen.
[0016] Specifically, the imaging display unit may have a first camera that takes images at a first magnification and a second camera that takes images at a second magnification that is higher than the first magnification, and the feeder setup work support device may be configured to change the magnification at which the camera takes images of the component supply position by selectively using the first camera and the second camera to capture images including the component supply position.
[0017] The feeder setup operation support device may further include a feeder control unit that causes the feeder attached to the feeder attachment unit to feed the component storage tape, and the feeder control unit adjusts the position of the component storage tape in the feed direction based on an image of the component supply position captured by the camera of the imaging display unit, thereby performing cueing to position the component storage tape at a predetermined initial position set for the component supply position. In this configuration, the feeder control unit controls the feeder to feed and cue the component storage tape, thereby reducing the workload on the worker.
[0018] The component storage tape may also have a plurality of pockets arranged at a predetermined pitch, and among the plurality of pockets, pockets within a predetermined range from the leading end do not store components, and pockets further rearward than the predetermined range store components, and the feeder setup work support device may be configured so that the component storage tape is positioned at its initial position by cueing, so that the rearmost pocket of the pockets within the predetermined range is positioned at the component supply position.
[0019] The component mounting system according to the present invention includes a component mounter that mounts components onto a board by transferring the components supplied to the component supply position by a feeder onto the board using a mounting head, and the feeder setup operation support device described above. Therefore, it is possible to support the worker's work by enabling the worker to easily and accurately check the component supply position of the feeder. [Effects of the Invention]
[0020] As described above, according to the present invention, it is possible to assist the worker in his / her work by enabling the worker to easily and accurately check the component supply position of the feeder. [Brief explanation of the drawings]

[0022] FIG. 1 is a plan view showing a schematic configuration of an example of a component mounting system according to the present invention. In FIG. 1 and the following figures, the horizontal X direction, the horizontal Y direction perpendicular to the X direction, and the vertical Z direction are indicated as appropriate. This component mounting system 1 has a component mounter 10 and a feeder setup workbench 6. Details of the feeder setup workbench 6 will be described later, and the component mounter 10 will be described first.
[0023] The component mounter 10 is equipped with a transport unit 12 that transports a board B in the X direction (board transport direction). This transport unit 12 has a pair of conveyors 121 arranged in parallel in the X direction on a base 11, and transports the board B in the X direction by the conveyors 121. The spacing between these conveyors 121 is changeable in the Y direction (width direction) that is perpendicular to the X direction, and the transport unit 12 adjusts the spacing between the conveyors 121 according to the width of the board B being transported. This transport unit 12 transports the board B from the upstream side in the X direction, which is the board transport direction, to a predetermined work position 123, and transports the board B, on which components E have been mounted at the work position 123, from the work position 123 to the downstream side in the X direction.
[0024] Two component supply units 21 are lined up in the X direction on each side of the conveying unit 12 in the Y direction, and each component supply unit 21 has multiple feeders 5 lined up in the X direction. Each feeder 5 is detachably attached to the component supply unit 21, and supplies components E to a component supply position Le at the tip of the component supply unit 21 on the conveying unit 12 side. The configuration of each feeder 5 will be described later.
[0025] The component mounter 10 is also provided with a pair of Y-axis rails 31 extending in the Y direction, a Y-axis ball screw 32 extending in the Y direction, and a Y-axis motor My that rotates and drives the Y-axis ball screw 32. An X-axis rail 34 is supported on the pair of Y-axis rails 31 so as to be movable in the Y direction and is fixed to the nut of the Y-axis ball screw 32. An X-axis ball screw 35 extending in the X direction and an X-axis motor Mx that rotates and drives the X-axis ball screw 35 are attached to the X-axis rail 34, and the head unit 4 is supported on the X-axis rail 34 so as to be movable in the X direction and is fixed to the nut of the X-axis ball screw 35. Therefore, the Y-axis motor My can rotate the Y-axis ball screw 32 to move the head unit 4 in the Y direction, or the X-axis motor Mx can rotate the X-axis ball screw 35 to move the head unit 4 in the X direction.
[0026] The head unit 4 has multiple (three) mounting heads 41 arranged in a line in the X direction, and is driven in the X and Y directions by an X-axis motor Mx and a Y-axis motor My. Each mounting head 41 picks up a component E with a nozzle at its bottom end, thereby mounting the component E supplied to the component supply position Le onto the board B at the work position 123.
[0027] FIG. 2 is a perspective view showing the configuration of the feeder, FIG. 3 is a plan view showing the configuration of the component supply tape that stores the components supplied by the feeder, and FIG. 4 is a diagram showing the feeder and the feeder setup work table. These figures show a feed direction Df and a width direction Dw. The feed direction Df is the direction in which the feeder 5 transports the component storage tape 72, and the width direction Dw is a direction perpendicular to the feed direction Df. Both the feed direction Df and the width direction Dw are horizontal. Furthermore, the side of the feed direction Df along which the feeder 5 sends the component storage tape 72 to supply components is treated as the forward direction Df1 of the feed direction Df, and the opposite side of the feed direction Df is treated as the reverse direction Df2 of the feed direction Df.
[0028] The feeder 5 has a feeder body 51 to which a component supply reel 71 is detachably attached. A component storage tape 72 is wound around the component supply reel 71. The component storage tape 72 has a plurality of pockets 721 arranged in a line at a predetermined pitch Pa in the feed direction Df, and components E are stored in the pockets 721. The component storage tape 72 has a width Wt in the width direction Dw. A predetermined range from the tip of the component storage tape 72 on the forward direction Df1 side is a lead portion 72l, and each pocket 721 belonging to the lead portion 72l is an empty pocket 721 that does not store components E. In other words, of the plurality of pockets 721, components E are stored in the pockets 721 on the reverse direction Df2 side of the lead portion 72l. Examples of components E include chip components such as integrated circuits, transistors, and capacitors.
[0029] Component IDs 711 that identify the components E stored on the component storage tape 72 are attached to the side of the component supply reel 71 that holds the component storage tape 72. The component IDs 711 are, for example, barcodes, and indicate the number, type, and size of the components E stored on the component storage tape 72, as well as the arrangement pitch Pa of the pockets 721. For example, if the components E are rectangular chip components, at least the width of the components E is indicated as the size of the components E. The component supply reel 71 is rotatably supported by the feeder body 51.
[0030] The feeder 5 also has a tape guide 52 attached to the top of the feeder main body 51. A component supply position Le is provided at the tip of this tape guide 52 on the forward direction Df1 side, and the tape guide 52 guides the component storage tape 72 pulled out from the component supply reel 71 to the component supply position Le. The tape guide 52 has a predetermined width Wf in the width direction Dw, and the width Wf of the tape guide 52 corresponds to the width of the feeder 5.
[0031] The feeder main body 51 also contains a sprocket 54 that engages with the component storage tape 72 guided by the tape guide 52, a feed motor Mf that rotates the sprocket 54, and a control board 55, which is an electronic circuit board that controls the feed motor Mf. The control board 55 rotates the sprocket 54 using the feed motor Mf, thereby feeding the component storage tape 72 in the feed direction Df. In particular, an operation panel 56 is provided on the rear surface of the feeder main body 51, and the control board 55 controls the feed motor Mf in response to operations on the operation panel 56 by an operator, thereby feeding the component storage tape 72 in the feed direction Df. The control board 55 also stores feeder width information Iw that indicates the width Wf of the feeder 5.
[0032] The feeder body 51 has front end faces 511 and 512, each perpendicular to the feed direction Df, at its end on the forward direction Df1 side. The front end face 511 is located above the front end face 512 and protrudes in the forward direction Df1 relative to the front end face 512. The front end face 511 has a plurality (two) of positioning protrusions 53 protruding from the front end face 511 in the forward direction Df1. The positioning protrusions 53 are arranged vertically and offset in the width direction Dw with respect to an imaginary center line Cw that passes through the center of the tape guide 52 in the width direction Dw and is parallel to the vertical direction. As a result, the positioning protrusions 53 are offset in the width direction Dw with respect to the center of the component supply position Le. The center of the component supply position Le can be determined, for example, as the center in the width direction Dw of the pocket 721 positioned at the component supply position Le. The front end face 512 also has a connector 57 for electrically connecting the control board 55 to the feeder setup work table 6.
[0033] As shown in FIG. 4 , the feeder setup workbench 6 includes a main body 61, which has a table 611 that supports the feeder 5 attached to the feeder setup workbench 6, leg members 612 that support the table 611 on the ground, and a frame 613 that extends upward from the table 611. A connector 62 is provided on the top surface of the table 611, and a plurality of (two) positioning holes 614 are provided on the back surface of the frame 613. The worker positions the feeder 5 relative to the feeder setup workbench 6 by connecting the connector 57 of the feeder 5 to the connector 62 of the feeder setup workbench 6 and engaging the plurality of positioning protrusions 53 of the feeder 5 with the plurality of positioning holes 614 of the feeder setup workbench 6. In this way, the feeder 5 is detachably attached to the feeder setup workbench 6 while being positioned on the feeder setup workbench 6. The manner in which the feeder 5 and the feeder setup work table 6 are positioned is not limited to the example given here, and they may also be positioned by engaging a hole provided in the feeder 5 with a protrusion provided on the feeder setup work table 6.
[0034] The feeder setup workbench 6 also includes a computer 63, which has a calculation unit 631 and a memory unit 632. The calculation unit 631 is configured with a processor such as a CPU (Central Processing Unit), and the memory unit 632 is configured with, for example, an HDD (Hard Disk Drive) or an SSD (Solid State Drive). The computer 63 communicates with the control board 55 of the feeder 5 via connectors 62 and 57.
[0035] The feeder setup workbench 6 also includes a scanner 64. The scanner 64 is, for example, a barcode scanner that reads the component ID 711. Therefore, when the worker points the scanner 64 toward the component ID 711 of the component supply reel 71, the scanner 64 reads the component ID 711 and transmits it to the computer 63.
[0036] Furthermore, the feeder setup workbench 6 has a camera 65 and a display 66. The camera 65 is attached to the frame 613 so as to face the component supply position Le from above, and captures an image of the component supply position Le from above. The display 66 is attached to the upper end of the frame 613, and displays the image captured by the camera 65 on a screen 661. The image capture by the camera 65 and the display by the display 66 are controlled by the computer 63. Specifically, the computer 63 acquires the image captured by the camera 65 and displays this image on the screen 661 of the display 66.
[0037] FIG. 5 is a diagram schematically illustrating the imaging field of view of the camera, and FIG. 6 is a diagram schematically illustrating an example of the display operation of an image captured by the camera. As shown in FIG. 5, the imaging field of view V of the camera 65 is set to include the component supply position Le of the feeder 5, and the camera 65 can capture an image within the imaging field of view V. The magnification at which the image captured by the camera 65 is displayed on the screen 661 of the display 66 can be changed as shown in FIG. 6. In the "Low Magnification" column of FIG. 6, the component supply position Le is displayed on the screen 661 of the display 66 at a low magnification, and the area occupied by the component supply position Le on the screen 661 of the display 66 is narrow. On the other hand, in the "High Magnification" column of FIG. 6, the component supply position Le is displayed on the screen 661 of the display 66 at a higher magnification than the low magnification, and the area occupied by the component supply position Le on the screen 661 of the display 66 is enlarged compared to that at the low magnification. In this way, the display range on the screen 661 can be adjusted by changing the magnification for display on the screen 661; specifically, by increasing the magnification, a narrower display range can be enlarged and displayed. This change in the magnification for display on the screen 661 can be implemented by changing the magnification for capturing an image of the component supply position Le by the camera 65 (i.e., optical zoom). This makes it possible to display an image of the component supply position Le captured at an appropriate magnification on the screen 661. However, it goes without saying that the change in the magnification for display on the screen 661 can also be implemented by image processing by the computer 63 (i.e., digital zoom).
[0038] 7 is a flowchart showing an example of a feeder setup operation by an operator using a feeder setup workbench. In step S101, the operator mounts feeder 5 on feeder setup workbench 6. This positions feeder 5 relative to feeder setup workbench 6, enabling communication between control board 55 of feeder 5 and computer 63 of feeder setup workbench 6.
[0039] In step S102, the worker uses the scanner 64 to read the component ID 711 attached to the component supply reel 71 newly attached to the feeder 5. As a result, the computer 63 acquires the information indicated by the component ID 711 read by the scanner 64. Also in step S102, the worker engages the component storage tape 72 pulled out from the component supply reel 71 with the sprocket 54.
[0040] In step S103, the worker operates the operation panel 56 of the feeder 5 while checking the component supply position Le displayed on the screen 661. Specifically, the worker operates the operation panel 56 to transport the component storage tape 72 in the forward direction Df1 while checking the image of the component supply position Le on the screen 661. As described above, a predetermined range from the leading end of the component storage tape 72 is the lead portion 72l. Therefore, initially, the screen 661 displays empty pockets 721 sequentially reaching the component supply position Le. Then, when the lead portion 72l passes the component supply position Le, the pocket 721 storing the component E reaches the component supply position Le. In response to this, when the worker checks on the screen 661 that the component E has reached the component supply position Le, he or she stops transport of the component storage tape 72. As a result, of the multiple components E stored on the component storage tape 72, the component E at the leading end in the forward direction Df1 is positioned at the component supply position Le.
[0041] In step S104, the operator operates the offset execution button on the operation panel 56 to cause the feeder setup work table 6 to execute offsetting. This offsetting will be described in detail next.
[0042] Fig. 8 is a flowchart showing a first example of feeder setup work support executed by the feeder setup work table, and Fig. 9 is a diagram showing an example of a table referenced in the feeder setup work support of Fig. 8. The feeder setup work support of Fig. 8 is executed under the control of the calculation unit 631 of the computer 63, in parallel with the feeder setup work by the worker shown in Fig. 7.
[0043] In step S201, the computer 63 confirms whether the feeder 5 has been attached to the feeder setup work table 6. The attachment of the feeder 5 can be confirmed based on the start of communication with the control board 55 via the connectors 62 and 57. In step S202, the computer 63 acquires the feeder width information Iw from the control board 55. This enables the computer 63 to confirm the width Wf of the feeder 5 attached to the feeder setup work table 6.
[0044] In step S203, the calculation unit 631 checks the existence range of the component supply position Le based on the feeder width information Iw. This confirmation of the existence range of the component supply position Le is performed using the table Twr of FIG. 9. This table Twr indicates the correspondence between the width Wf(n) of the feeder 5 and the existence range R(n) of the component supply position Le of the feeder 5 (n = 1, 2, 3, ...). The existence range R(n) indicates, for example, the center coordinates of the component supply position Le and its width in the width direction Dw. Such a table Twr is obtained by an operator or the like and stored in advance in the storage unit 632.
[0045] Therefore, the calculation unit 631 acquires the existence range R(n) of the component supply position Le by identifying the existence range R(n) corresponding to the width Wf indicated by the feeder width information Iw from the table Twr. One of the reasons for acquiring the existence range R of the component supply position Le in this way is that the positioning protrusion 53 is offset from the imaginary center line Cw in the width direction Dw. In other words, because the positioning protrusion 53 is offset, the positional relationship between the camera 65 and the component supply position Le varies greatly depending on the width Wf of the feeder 5. In response to this, the existence range R(n) of the component supply position Le is acquired in order to accurately capture and display the component supply position Le.
[0046] In step S204, the calculation unit 631 adjusts the display range on the screen 661 in accordance with the existence range R(n) of the component supply position Le so that the display range on the screen 661 fits the existence range R(n) of the component supply position Le. Then, in step S205, the display range set in step S204 is displayed on the screen 661. For example, if the display range is not adjusted in step S204, the display range as shown in the "low magnification" column in Fig. 6 is displayed on the screen 661, whereas by adjusting the display range in step S204, the display range as shown in the "high magnification" column in Fig. 6 is displayed on the screen 661.
[0047] In step S206, the calculation unit 631 checks whether the scanner 64 has read the component ID 711. Then, when the calculation unit 631 acquires the component ID 711 read by the scanner 64 ("YES" in step S206), it acquires the pitch Pa indicated by this component ID 711 (step S207).
[0048] In step S208, the calculation unit 631 checks whether the offset execution button on the operation panel 56 has been operated. Then, when the calculation unit 631 checks whether the offset execution button has been operated ("YES" in step S208), it sends a command to the control board 55 to feed the component storage tape 72 in the reverse direction Df2 by the pitch Pa. Upon receiving this command, the control board 55 rotates the sprocket 54 using the feed motor Mf to feed the component storage tape 72 in the reverse direction Df2 by the pitch Pa. Note that, as described in steps S103 and S104 above, the offset execution button is operated when, of the multiple components E stored on the component storage tape 72, the leading component E in the forward direction Df1 is positioned at the component supply position Le. Therefore, by executing the offset in step S209, the empty pocket 721 furthest in the reverse direction Df2 (the rear end) among the pockets 721 of the lead portion 72l is positioned at the component supply position Le.
[0049] In the embodiment described above, an image including the component supply position Le is captured by the camera 65 and displayed on the screen 661 (for example, the "high magnification" column in FIG. 6). Therefore, the worker can visually check the component supply position Le by looking at the screen 661. However, if the range displayed on the screen 661 is not appropriate for the component supply position Le, for example, a part of the component supply position Le may extend outside the screen 661, or the range in which the component supply position Le is displayed on the screen 661 may be too narrow (for example, the "low magnification" column in FIG. 6). Therefore, in the above embodiment, the range displayed on the screen 661 is adjusted based on the feeder width information Iw (display target information) related to the component supply position Le to be displayed. This makes it possible to display an appropriate range for the component supply position Le on the screen 661. In this way, it is possible to support the worker's work by enabling the worker to easily and accurately check the component supply position Le of the feeder 5.
[0050] Furthermore, the computer 63 adjusts the range to be displayed on the screen 661 based on the width Wf of the feeder 5 indicated by the feeder width information Iw. In other words, the component supply position Le of the feeder 5 differs depending on the width Wf of the feeder 5, and therefore the range to be displayed on the screen 661 changes. Therefore, by configuring as described above, it is possible to display an appropriate range for the component supply position Le on the screen 661 for each of multiple types of feeders 5 with different widths Wf.
[0051] Furthermore, the feeder 5 has a control board 55 (storage unit) that stores the feeder width information Iw. In response to this, the computer 63 acquires the feeder width information Iw by reading it from the control board 55 of the feeder 5 attached to the main body 61 (feeder attachment unit) of the feeder setup workbench 6. With this configuration, it is possible to accurately acquire the width Wf of the feeder 5 attached to the main body 61 of the feeder setup workbench 6 for feeder setup work, and to display an appropriate range for the component supply position Le of this feeder 5 on the screen 661.
[0052] Figure 10 is a diagram showing a schematic diagram of the operation of a second example of feeder setup work support performed by a feeder setup work table. Here, the differences from the first example will be mainly explained, and the same reference numerals will be used to designate common parts, and explanations will be omitted as appropriate. As can be seen from the size ratio of parts El and Es relative to the part supply position Le in Figure 10, in the width direction Dw, the width We of part Es shown in the "Small Parts" column of Figure 10 is smaller than the width We of part El shown in the "Large Parts" column of Figure 10.
[0053] 10, the display range on the screen 661 is changed according to the width We of the parts El and Es. That is, when the calculation unit 631 acquires a part ID 711, it checks the width We of the part E indicated by the part ID 711. Then, the display range imaged by the camera 65 and displayed on the screen 661 is adjusted according to the width We of the part E. Specifically, the magnification when displaying a part Es (small part) with a smaller width We compared to the large part El is set higher than the magnification when displaying a part El (large part) with a larger width We. This makes it possible to narrow the display range when displaying small parts Es compared to the display range when displaying large parts El, and to enlarge and display small parts Es.
[0054] As described above, in the second example, the computer 63 adjusts the range displayed on the screen 661 based on the width We of the component E indicated by the component ID 711 (component size information). In this configuration, the range displayed on the screen 661 is adjusted according to the width We of the components El and Es supplied to the component supply position Le. This makes it possible to support the worker's work by enabling the worker to easily and accurately check the components El and Es supplied to the component supply position Le of the feeder 5.
[0055] Furthermore, the computer 63 acquires the widths We of the parts El and Es indicated by the part IDs 711 read by the scanner 64 (reading unit). With this configuration, the sizes of the parts El and Es to be supplied to the part supply position Le by the feeder 5 that is the target of the feeder setup work can be accurately acquired, and an appropriate range for the parts El and Es to be supplied to the part supply position Le of this feeder 5 can be displayed on the screen 661.
[0056] Fig. 11 is a diagram schematically showing a modified example of the feeder setup workbench, and Fig. 12 is a diagram schematically showing the imaging field of the camera of the feeder setup workbench according to the modified example of Fig. 11. The feeder setup workbench 6 according to this modified example differs from the above-described feeder setup workbench 6 in that it is equipped with two cameras 65a, 65b, but is common to the above-described feeder setup workbench 6 in other respects.
[0057] Of the two cameras 65a and 65b, camera 65a is a low-magnification camera that images component supply position Le at a low magnification, and camera 65b is a high-magnification camera that images component supply position Le at a higher magnification than camera 65a. Due to this difference in magnification, the imaging field of view Vb of camera 65b is narrower than the imaging field of view Va of camera 65a. Note that both imaging fields of view Va and Vb include component supply position Le, and imaging field of view Vb is included in the imaging field of view Va. Computer 63 changes the display range on screen 661 by switching one of cameras 65a and 65b to be used to image component supply position Le.
[0058] That is, in this modified example, a camera 65a (first camera) that takes an image at a low magnification (first magnification) and a camera 65b (second camera) that takes an image at a higher magnification (second magnification) than the low magnification are provided. Then, by selectively using the camera 65a and the camera 65b to take an image including the component supply position Le, the magnification at which the camera 65 takes an image of the component supply position Le is changed. This makes it possible to display on the screen 661 an image taken at an appropriate magnification according to the existence range R(n) of the component supply position Le and the size (width We) of the component E to be supplied to the component supply position Le.
[0059] Fig. 13 is a flowchart showing an example of a cueing process automatically performed by the feeder setup work table. The flowchart in Fig. 13 is executed under the control of the calculation unit 631 of the computer 63, and performs the cueing of the component storage tape 72 that has been attached to the feeder 5 by the operator.
[0060] In step S301, it is determined whether an instruction to execute cueing has been input by the operator to the operation panel 56. Then, when the input of the instruction to execute cueing is confirmed (YES in step S301), the calculation unit 631 starts capturing an image of the component supply position Le with the camera 65 to obtain an image of the component supply position Le (step S302). In addition, the calculation unit 631 starts transporting the component storage tape 72 in the forward direction Df1.
[0061] In this way, the calculation unit 631 monitors the image of the component supply position Le while transporting the component storage tape 72 in the forward direction Df1, thereby confirming whether the component E has reached the component supply position Le (step S304). That is, as described above, a predetermined range from the leading end of the component storage tape 72 is the lead portion 72l, so initially, images of multiple pockets 721 passing the component supply position Le in sequence are acquired. On the other hand, when the lead portion 72l passes the component supply position Le, an image of the component E that has reached the component supply position Le is acquired. This allows the calculation unit 631 to confirm that the component E has reached the component supply position Le ("YES" in step S304).
[0062] After confirming that component E is at component supply position Le, the calculation unit 631 stops the feeding of the component storage tape 72 and positions component E at component supply position Le (step S305). Next, the calculation unit 631 feeds (offsets) the component storage tape 72 in the reverse direction Df2 by the pitch Pa. This completes the cuff alignment process, positioning the pocket 721 furthest in the reverse direction Df2 (rear end side) of the pockets 721 in the lead portion 72l (predetermined range) at component supply position Le.
[0063] 13, the computer 63 (feeder control unit) adjusts the position of the component storage tape 72 in the feed direction Df using the feeder 5 based on an image of the component supply position Le captured by the camera 65, thereby performing a cueing operation to position the component storage tape 72 at a predetermined initial position relative to the component supply position Le. Here, the initial position is the position of the component storage tape 72 when the pocket 721 on the leading portion 72l that is furthest to the reverse direction Df2 is located at the component supply position Le. In this way, the computer 63 controls the feeder 5 to transport the component storage tape 72 and automatically perform the cueing operation. This reduces the workload on the operator.

[0065] The present invention is not limited to the above-described embodiment, and various modifications can be made to the above-described embodiment without departing from the spirit of the present invention. For example, the first and second examples of the feeder setup work support may be used together, or only one of them may be executed. In the former case, the display range on the screen 661 is adjusted based on both the existence range R(n) of the component supply position Le and the width We of the component E indicated by the component ID 711. In the latter case, the display range on the screen 661 is adjusted based on either the existence range R(n) of the component supply position Le or the width We of the component E indicated by the component ID 711.
[0066] Furthermore, when adjusting the display range on the screen 661 based on the size of the part E, the size to be referenced is not limited to the width We of the part E described above, but may also be, for example, the length of the part E in the feed direction Df or the area of the top surface of the part E.
[0067] Furthermore, the method of acquiring the feeder width information Iw indicating the width Wf of the feeder 5 may be by actually measuring it rather than acquiring it from the control board 55 as described above. In this modification, the calculation unit 631 of the computer 63 captures an image of the tape guide 52 of the feeder 5 using the camera 65 to acquire a tape guide image. Then, the width Wf of the feeder 5 is acquired by extracting the width Wf of the tape guide 52 indicated by this tape guide image. According to this modification, the width Wf of the feeder 5 can be reliably acquired even in a situation where the feeder width information Iw has not been prepared in advance.
[0068] Furthermore, the type of feeder 5 is not limited to a cassette type in which the component supply reel 71 is attached to the feeder body 51 of the feeder 5. For example, the above-described embodiment can be similarly implemented in setup work for a feeder 5 that transports the component storage tape 72 pulled out from the component supply reel 71 arranged separately from the feeder body 51 in the feed direction Df.
[0069] Furthermore, if the width Wf of the feeder 5 that transports the component storage tape 72 varies depending on the width of the component storage tape 72, the range displayed on the screen 661 may be adjusted based on the width Wt of the component storage tape 72 instead of the width Wf of the feeder 5. Such a modification will be described next with reference to FIG.
[0070] 14 is a diagram showing a schematic diagram of a third example of the operation of the feeder setup work support performed by the feeder setup work table. In the third example, the component ID 711 attached to the component supply reel 71 includes tape width information (display target information) that indicates the width Wt of the component storage tape 72 held by the component supply reel 71.
[0071] In step S401, the calculation unit 631 checks whether the scanner 64 has read the component ID 711. Then, when the calculation unit 631 acquires the component ID 711 read by the scanner 64 ("YES" in step S401), it acquires the tape width information included in this component ID 711 (step S402).
[0072] In step S403, the calculation unit 631 checks the location range of the component supply position Le based on the tape width information. Specifically, a table like table Twr shown in FIG. 9 is prepared for the width Wt of the component storage tape 72. In other words, the table prepared in the third example indicates the correspondence between the width Wt(n) of the component storage tape 72 and the location range R(n) of the component supply position Le of the feeder 5 (n = 1, 2, 3, ...). Such a table is generated by an operator or the like and stored in advance in the storage unit 632. Therefore, the calculation unit 631 obtains the location range R(n) of the component supply position Le by identifying the location range R(n) corresponding to the width Wt indicated by the tape width information from this table. Thereafter, steps S204 to S205 and S207 to S209 are executed in the same manner as in the first example.
[0073] In this third example as well, an image including the component supply position Le is captured by the camera 65 and displayed on the screen 661. Therefore, the worker can confirm the component supply position Le by visually checking this screen 661. However, if the range displayed on the screen 661 is not appropriate for the component supply position Le, for example, part of the component supply position Le may extend outside the screen 661, or the range in which the component supply position Le is displayed on the screen 661 may be too narrow. Therefore, the range displayed on the screen 661 is adjusted based on the tape width information (display target information) related to the component supply position Le to be displayed. This makes it possible to display an appropriate range for the component supply position Le on the screen 661. In this way, it is possible to support the worker's work by enabling the worker to easily and accurately confirm the component supply position Le of the feeder 5.
[0074] Furthermore, the computer 63 adjusts the range to be displayed on the screen 661 based on the width Wt of the component storage tape 72 indicated by the tape width information. In other words, the width Wf of the feeder 5 used to transport the component storage tape 72 may change depending on the width Wt of the component storage tape 72. In contrast, the component supply position Le of the feeder 5 differs depending on the width Wf of the feeder 5, and therefore the range to be displayed on the screen 661 changes. Therefore, by configuring as described above, it is possible to display an appropriate range for the component supply position Le on the screen 661 while dealing with the difference in the width Wf of the feeder 5 depending on the width Wt of the component storage tape 72.
