[0007] Problems to be solved by the invention

[0008] In conventional component supply devices such as International Publication No. 2018 / 070047, the blade becomes blunt due to use, making it difficult to cut the top tape. The top tape peels off from the carrier tape and becomes clogged, which in turn signals the end of the blade's life. Consequently, the blade's end of life may be detected, making it impossible to cut the top tape, and the component supply device may be unable to supply components. Therefore, a component supply device and component mounting device that can prevent the top tape from being cut and reliably supply components are desired.

[0009] The present invention has been made to solve the above-mentioned problems, and one object of the present invention is to provide a component supply device and a component mounting device that can reliably supply components while preventing the top tape from being cut.

[0010] Means for solving problems

[0011] The component supply device of the first embodiment of the present invention comprises: a belt conveying section for conveying a belt including a storage section for storing components and a top cover covering the storage section; a knife section for cutting the top cover of the belt conveyed by the belt conveying section; and a marking section for confirming the life of the knife section.

[0012] In the component supply device of the first aspect of the present invention, by being configured as described above, the life of the knife portion can be confirmed by the marking portion, so the knife portion can be replaced before the top tape cannot be cut by the knife portion. Thus, components can be reliably supplied without the top tape being cut.

[0013] In the component supply device of the first aspect described above, it is preferred that the blade portion be formed to have a tapered shape from the downstream side toward the upstream side in the conveying direction of the tape conveyor portion, and be configured so that the position at which the top tape is cut shifts from the upstream side to the downstream side in the conveying direction as the top tape is used, and the marking portion be configured so that the life of the blade portion can be identified by comparing the position in the conveying direction at which the top tape is cut by the blade portion. With this configuration, by comparing the position at which the top tape is cut by the blade portion with the marking portion, the life of the blade portion can be confirmed and the period until the end of the life can be estimated, thereby making it easy to determine the timing for replacing the blade portion.

[0014] In this case, preferably, the position of the conveying direction that the mark portion is cut by the knife portion about the top band is configured in the mode of the position of the life-span of expression knife portion.If constitute like this, then by relatively utilizing the position and the mark portion that the top band is cut by the knife portion, the life-span of knife portion can be confirmed more easily.

[0015] In the component supply device of the first aspect, the marking portion is preferably provided linearly to indicate the position of the life of the blade. With this configuration, the life of the blade can be easily checked by checking the linear marking portion.

[0016] In the component supply device of the first aspect, it is preferable that the marking portion is arranged on the upper surface of the blade portion. With this configuration, the marking portion can be easily confirmed from above the blade portion.

[0017] In the component supply device of the first aspect, it is preferred that a top tape guide be further provided to guide the top tape cut by the knife portion so as to expand it in the width direction, and the marking portion be disposed on the upper surface of the top tape guide. With this configuration, even when the knife portion is inserted under the top tape to cut the top tape, the marking portion will not be covered by the top tape, unlike when the marking portion is disposed on the knife portion, and thus the marking portion can be reliably identified from above.

[0018] The component supply device of the first aspect preferably further includes an inspection unit, including an inspection imaging unit for capturing images for inspecting the conveying status of the belt of the belt conveyor. The inspection unit is configured to capture images of the marking portion and the blade using the inspection imaging unit and to verify the life of the blade based on the captured images. With this configuration, the inspection imaging unit automatically verifies the life of the blade by capturing images of the marking portion and the blade, eliminating the need for the operator to visually inspect the marking portion. This allows verification of the life of the blade while minimizing the workload on the operator.

[0019] In this case, preferably, the inspection unit is configured to: when being judged as the knife portion has reached the life span, urge the notice of the replacement of the knife portion. If constituted like this, then by the notice of the replacement of the knife portion from the inspection unit, the operator can easily identify the timing of the replacement of the knife portion.

[0020] The component mounting device of the second scheme of the present invention comprises: a component supply device; and a mounting head, which mounts the components supplied from the component supply device onto the substrate, the component supply device includes: a belt conveying part, which conveys the belt, wherein the belt includes a storage part for storing the components and an upper sealing tape covering the upper part of the storage part; a knife part, which cuts the upper sealing tape of the belt conveyed by the belt conveying part; and a marking part, which is used to confirm the life of the knife part.

[0021] In the component mounting device of the second aspect of the present invention, the above-described configuration allows the life of the blade to be confirmed using the marking portion, thereby enabling the blade to be replaced before the top tape becomes inoperable. This provides a component mounting device that can reliably supply components while preventing the top tape from being cut.

[0022] The component mounting device of the second aspect preferably further comprises: a component imaging unit mounted on the head unit so as to be movable horizontally along with the mounting head and configured to image the component supply position of the component supply device; and a control unit configured to use the component imaging unit to image the marking portion and the blade portion and to verify the life of the blade portion based on the captured images. With this configuration, the control unit automatically verifies the life of the blade portion by imaging the marking portion and the blade portion using the component imaging unit, eliminating the need for the operator to visually verify the marking portion. This allows the life of the blade portion to be verified while minimizing the operator's workload.

[0023] In this case, preferably, control unit is constituted as: when being judged as knife portion has reached the situation of life-span, urges the notice of the replacement of knife portion.If constitute like this, then by the notice of the replacement of the knife portion from control unit, the operator can easily identify the timing of the replacement of knife portion.

[0024] In the component mounting apparatus of the second aspect, the control unit is preferably configured to control the component imaging unit to image the marking portion based on at least one of the number of times the tape is fed by the tape conveying unit of the component supply device, the distance the tape is fed by the tape conveying unit of the component supply device, and an error in the suction of the component from the tape by the mounting head. With this configuration, it is possible to prevent the component imaging unit from excessively capturing the marking portion, thereby preventing an increase in component mounting operation time due to the component imaging unit capturing the marking portion.

[0036] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0037] (Structure of component mounting device)

[0038] Reference Figure 1 , the structure of the component mounting device 100 according to one embodiment of the present invention will be described.

[0039] like Figure 1 As shown, the component mounting apparatus 100 is a component mounting apparatus that transports the substrate P in the X direction using a pair of conveyors 2 and mounts the component 31 on the substrate P at a mounting work position M.

[0040] The component mounting apparatus 100 includes a base 1 , a pair of conveyors 2 , a component supply section 3 , a head unit 4 , a support section 5 , a pair of rail sections 6 , a component recognition and imaging section 7 , and a control section 8 .

[0041] A pair of conveyors 2 is provided on the base 1 and is configured to transport the substrate P in the X direction. Furthermore, the pair of conveyors 2 is provided with a holding mechanism for holding the substrate P being transported while stopped at the mounting operation position M. Furthermore, the pair of conveyors 2 is configured so that the spacing between them in the Y direction can be adjusted according to the size of the substrate P.

[0042] The component supply unit 3 is arranged outside (Y1 side and Y2 side) of the pair of conveyors 2. A plurality of component supply devices 10 are arranged in the component supply unit 3. The plurality of component supply devices 10 in the component supply unit 3 are configured to supply components 31 to a mounting head 42 described below.

[0043] like Figure 2 As shown, the component supply device 10 holds a reel 33 wound with a tape 32 that holds multiple components 31 at predetermined intervals. In other words, the component supply device 10 is configured as a tape feeder. The component supply device 10 is configured to feed the tape 32 holding the components 31, causing the reel 33 to rotate, thereby supplying the components 31 from the Y-direction end of the component supply device 10. Here, the components 31 include electronic components such as ICs, transistors, capacitors, and resistors. A detailed description of the component supply device 10 will be provided later.

[0044] like Figure 1 As shown, the head unit 4 is arranged above the pair of conveyors 2 and the component supply unit 3 and includes a plurality of (five) mounting heads 42 with suction nozzles 41 attached to the lower ends thereof and a board recognition camera 43 .

[0045] The mounting head 42 is configured to mount the component 31 supplied from the component supply device 10 on the substrate P. Specifically, the mounting head 42 is configured to suck the component 31 supplied by the component supply unit 3 and supply the sucked component 31 to the substrate P arranged at the mounting operation position M. In addition, the mounting head 42 is configured to be able to rise and fall (movable in the Z direction). In addition, the mounting head 42 is configured to suck and hold the component 31 supplied from the component supply device 10 by using the negative pressure generated at the top end of the suction nozzle 41 by a negative pressure generator (not shown), and assemble (mount) the component 31 to the mounting position on the substrate P.

[0046] The substrate recognition camera 43 is provided on the head unit 4 in such a manner as to be movable in the horizontal direction (XY direction) together with the mounting head 42. In addition, the substrate recognition camera 43 is configured to photograph the reference mark F of the substrate P in order to identify the position and posture of the substrate P. Moreover, by photographing and identifying the position of the reference mark F, the mounting position of the component 31 in the substrate P can be accurately obtained. In addition, the substrate recognition camera 43 is configured to photograph the component supply position (component removal portion 132) of the component supply device 10. In addition, the substrate recognition camera 43 is configured to be able to photograph the exposed portion 131 of the component supply device 10. It should be noted that the substrate recognition camera 43 is an example of a "component photographing portion" in the claims.

[0047] The support portion 5 includes a motor 51. The support portion 5 is configured to move the head unit 4 in the X direction along the support portion 5 by driving the motor 51. Both ends of the support portion 5 are supported by a pair of rail portions 6.

[0048] A pair of rails 6 are fixed to the base 1. The rail 6 on the X1 side includes a motor 61. The rail 6 is configured so that the support 5 moves along the pair of rails 6 in the Y direction, which is perpendicular to the X direction, by driving the motor 61. Since the head unit 4 can move in the X direction along the support 5, and the support 5 can move in the Y direction along the rails 6, the head unit 4 can move in the horizontal direction (XY direction).

[0049] The component recognition and imaging unit 7 is fixed to the upper surface of the base 1. The component recognition and imaging unit 7 is located outside the pair of conveyors 2 (on the Y1 side and the Y2 side). The component recognition and imaging unit 7 is configured to capture an image of the component 31 being held by the suction nozzle 41 of the mounting head 42 from below (on the Z2 side) in order to identify the suction state (suction posture) of the component 31 before mounting. This allows the control unit 8 to obtain the suction state of the component 31 held by the suction nozzle 41 of the mounting head 42.

[0050] The control unit 8 includes a CPU and a memory, and is configured to control the overall operation of the component mounting device 100, such as the transport operation of the pair of conveyors 2 to the substrate P, the mounting operation of the head unit 4, the imaging operation of the component recognition imaging unit 7 and the substrate recognition camera 43. In addition, the control unit 8 is configured to be able to communicate with the control unit 11 of the component supply device 10 (see Figure 2 The control unit 8 is configured to cooperate with the control units 11 of the plurality of component supply devices 10 to control the mounting operation.

[0051] (Structure of Component Supply Device)

[0052] Reference Figures 2 to 8 , the structure of the component supply device 10 according to the embodiment of the present invention will be described.

[0053] like Figure 2 As shown, the component supply device 10 includes a control unit 11, tape conveying units 12a and 12b, and a tape guide 13. The tape guide 13 is provided with an exposure portion 131 and a component removal portion 132. The component supply device 10 is a feeder capable of automatically loading the tape 32.

[0054] like Figure 3 and Figure 4 As shown, the belt 32 includes a carrier belt 321 and a top cover belt 322. The carrier belt 321 is provided with a storage portion 321a for storing the component 31 and an engagement hole 321b that engages with the belt conveyor portions 12a and 12b. The storage portion 321a has a space that is larger than the size of the component 31. The top of the storage portion 321a is covered by the top cover belt 322. This prevents the component 31 from coming out of the storage portion 321a before the component is supplied. When the component is supplied, the top cover belt 322 is cut, and the top of the storage portion 321a is exposed. Thus, the component 31 can be taken out of the storage portion 321a using the mounting head 42 at the component removal portion 132. The plurality of engagement holes 321b are arranged at a constant interval from each other. In addition, the engagement holes 321b are arranged at a predetermined relative position relative to the storage portion 321a.

[0055] The control unit 11 is configured to control the driving of the component supply device 10. Specifically, the control unit 11 is configured to control the driving of the belt conveying units 12a and 12b to control the conveying operation of the belt 32. The control unit 11 includes a substrate having a control circuit. Furthermore, the control unit 11 is configured to control the conveying operation of the belt 32 based on the detection results of the belt 32 by a sensor (not shown) provided in the component supply device 10.

[0056] The belt conveyor sections 12a and 12b each include a sprocket. The sprockets of the belt conveyor sections 12a and 12b are configured to engage with the engagement holes 321b of the belt 32 to convey the belt 32 along the belt conveying direction A. The belt conveyor section 12a is located downstream of the exposed portion 131 in the belt conveying direction A. The belt conveyor section 12b is located on the inlet side (upstream side) of the belt 32 of the component supply device 10 in the belt conveying direction A.

[0057] The belt conveyor 12a is located below the conveying path of the belt 32. The belt conveyor 12b is located above the conveying path of the belt 32. The belt conveyors 12a and 12b are driven by the control unit 11. The belt conveyors 12a and 12b are set to a minimum rotation amount. This sets the minimum pitch of the conveyor belts 32.

[0058] The belt guide 13 is configured to press the belt 32 from above and guide it along the belt conveying direction A. The belt guide 13 is also disposed in a downstream region in the belt conveying direction A, including the component removal portion 132. The belt guide 13 minimizes the vertical dimension of the conveying path of the belt 32, thereby suppressing vertical shaking of the belt 32 in the downstream region in the belt conveying direction A.

[0059] The exposed portion 131 is configured to release the cover of the storage portion 321a by the top tape 322 so as to expose (open) the upper portion of the storage portion 321a. Figure 3 and Figure 4 As shown, the exposed portion 131 includes a knife portion 131 a (cutter) and a top tape guide 131 b.

[0060] The blade portion 131a is configured so that the blade tip is inserted between the carrier tape 321 and the top tape 322 to cut the top tape 322. In other words, the blade portion 131a is configured to sequentially cut the top tape 322 as the tape 32 moves. The top tape guide 131b is configured to expand the top tape 322, cut by the blade portion 131a, to both sides in the width direction (X direction). In other words, the top tape guide 131b is configured to sequentially open the top tape 322 in the width direction (X direction) as the tape 32 moves.

[0061] In addition, the blade portion 131a is formed into a tapered shape from the downstream side toward the upstream side in the conveying direction A of the belt conveying portions 12a and 12b for the belt 32. Figure 3 As shown, the blade portion 131a is formed so as to become tapered in the width direction (X direction) from the downstream side toward the upstream side in the conveying direction A. Figure 4 As shown, the blade portion 131 a is formed so as to become tapered in the vertical direction (Z direction) from the downstream side toward the upstream side in the conveying direction A.

[0062] The component removal portion 132 is provided at the downstream portion of the tape guide 13 in the tape conveying direction A. Specifically, the component removal portion 132 is provided downstream of the exposed portion 131 in the tape conveying direction A. A rectangular hole is provided in the component removal portion 132 that passes through in the vertical direction (Z direction). This allows the upper portion of the component 31 stored in the storage portion 321a to be opened, allowing the component 31 to be removed by the mounting head 42.

[0063] like Figure 5 As shown, the tape guide 13 is configured to be detachable from the main body of the component supply device 10. When the blade 131a becomes dull due to use and reaches the end of its life, the tape guide 13 is detached and the blade 131a is replaced.

[0064] Here, in this embodiment, Figure 6and Figure 7 As shown, the component supply device 10 includes a marking portion 14. The marking portion 14 is provided to check the life of the blade portion 131a.

[0065] The position where the knife portion 131a cuts the upper sealing tape 322 is shifted from the upstream side to the downstream side in the conveying direction A due to use. That is, in the normal case when the knife portion 131a is not blunt, as shown in FIG. Figure 6 As shown in FIG. 1 , the upper sealing tape 322 is cut at position A1 on the upstream side in the conveying direction A. In addition, if the knife portion 131a becomes blunt and no longer sharp, the position where the upper sealing tape 322 is cut will move toward the downstream side. Figure 7 As shown, at a position A2 on the downstream side in the conveying direction A, the top tape 322 is cut.

[0066] Furthermore, in this embodiment, the marking portion 14 is configured to identify the lifespan of the blade 131a by comparing it with the position in the conveying direction A where the top tape 322 is cut by the blade 131a. This allows for the blade 131a to be replaced at an appropriate time, preventing the top tape 322 from being cut. Consequently, it is possible to prevent the component 31 from being exposed again, thereby preventing the component mounting apparatus 100 from halting its mounting operation due to an incorrect suction of the component 31 by the mounting head 42. This improves productivity.

[0067] Furthermore, the marking portion 14 is positioned relative to the position in the conveying direction A where the top tape 322 is cut by the blade portion 131a, indicating the lifespan of the blade portion 131a. For example, when the position in the conveying direction A where the top tape 322 is cut by the blade portion 131a reaches the marking portion 14, the lifespan of the blade portion 131a has expired. Furthermore, the lifespan position of the blade portion 131a is the position in the conveying direction A of the blade portion 131a corresponding to the height at which the adhesive tape bond between the top tape 322 and the carrier tape 321 is separated. In other words, because the height of the blade portion 131a (the thickness of the blade) increases toward the downstream side, if the top tape 322 is conveyed downstream without being cut by the blade portion 131a, it may separate from the carrier tape 321. In this case, the top tape guide 131b cannot expand the peeled top tape 322 in the width direction, causing the peeled top tape 322 to become stuck.

[0068] Furthermore, the marking portion 14 is provided linearly to indicate the position of the lifespan of the blade portion 131a. Specifically, the marking portion 14 is formed into a straight line extending in the width direction (X direction). Furthermore, the marking portion 14 is disposed on the upper surface of the blade portion 131a. Furthermore, the marking portion 14 has a different color than the blade portion 131a. This makes it easy to identify the marking portion 14.

[0069] In addition, in the present embodiment, the control unit 8 is configured to photograph the marking portion 14 and the knife portion 131a using the substrate recognition camera 43, and to confirm the life of the knife portion 131a based on the photographed image. Specifically, the control unit 8 determines whether the position where the top tape 322 is cut by the knife portion 131a is upstream of the marking portion 14 in the conveying direction A based on the image photographed by the substrate recognition camera 43. Furthermore, if the position where the top tape 322 is cut by the knife portion 131a is upstream of the marking portion 14 in the conveying direction A, the control unit 8 determines that the knife portion 131a can still be used. On the other hand, if the position where the top tape 322 is cut by the knife portion 131a is not upstream of the marking portion 14 in the conveying direction A (reaching the marking portion 14), the control unit 8 determines that the knife portion 131a has reached its life.

[0070] Furthermore, the control unit 8 is configured to issue a notification urging the replacement of the blade 131a when it is determined that the blade 131a has reached its lifespan. Specifically, the control unit 8 controls the display unit (not shown) to display a message urging the replacement of the blade 131a of the corresponding component supply device 10 (tape feeder).

[0071] In addition, the control unit 8 is configured to control the use of the substrate recognition camera 43 to photograph the marking portion 14 based on at least one of the number of times the belt conveying portions 12a and 12b of the component supply device 10 convey the belt 32, the conveying distance of the belt 32 by the belt conveying portions 12a and 12b of the component supply device 10, and the errors in the adsorption of the component 31 from the belt 32 by the mounting head 42.

[0072] For example, when the belt 32 has been conveyed a predetermined number of times or more, the control unit 8 uses the board recognition camera 43 to image the marking portion 14 and confirm the state of the blade 131a. Furthermore, when the belt 32 has been conveyed a predetermined distance or more, the control unit 8 uses the board recognition camera 43 to image the marking portion 14 and confirm the state of the blade 131a. Furthermore, when a component 31 suction error occurs with the mounting head 42, the control unit 8 uses the board recognition camera 43 to image the marking portion 14 and confirm the state of the blade 131a.

[0073] In addition, the life of the blade portion 131 a can be confirmed by an operator visually checking or confirming an image captured by the board recognition camera 43 during maintenance.

[0074] In addition, the life of the blade 131a can also be confirmed in the following manner: Figure 8 This is performed when the component supply device 10 is inspected by the inspection unit 15 as shown.

[0075] The inspection unit 15 is provided to inspect the conveyance state of the belt 32 of the component supply device 10 each time the component supply device 10 supplies the component 31 a predetermined number of times (e.g., 5 million times). The inspection unit 15 inspects the component supply device 10 offline, with the component supply device 10 removed from the component mounting device 100.

[0076] The inspection unit 15 includes a control unit 151 and an inspection imaging unit 152. The control unit 151 is configured to control the component supply device 10 for inspection to perform connection.

[0077] The inspection unit 15 inspects the conveyance states of the tape conveying units 12 a and 12 b of the component supply device 10 while conveying a metal master tape instead of the tape 32 by the component supply device 10 .

[0078] Furthermore, the inspection unit 15 checks the state of the blade 131 a of the component supply device 10 while conveying the dummy tape with the top tape 322 that does not contain the component 31 to the component supply device 10 .

[0079] The inspection imaging unit 152 captures images for inspecting the conveying state of the tape conveying units 12a and 12b during inspection of the component supply device 10. Furthermore, the inspection imaging unit 152 captures images for inspecting the state of the blade 131a during inspection of the component supply device 10.

[0080] The control unit 151 of the inspection unit 15 is configured to use the inspection imaging unit 152 to capture images of the marking portion 14 and the blade 131a, and to check the life of the blade 131a based on the captured images. Furthermore, if the control unit 151 of the inspection unit 15 determines that the blade 131a has reached its life, it is configured to issue a notification urging replacement of the blade 131a.

[0081] (Effects of the embodiment)

[0082] In this embodiment, the following effects can be obtained.

[0083] In this embodiment, as described above, a marking portion 14 is provided for confirming the life of the blade 131a that cuts the top tape 322 of the belt 32. Thus, the life of the blade 131a can be confirmed using the marking portion 14, so the blade 131a can be replaced before it becomes impossible to cut the top tape 322. This prevents the top tape 322 from being cut and allows for reliable supply of the component 31.

[0084] In addition, in this embodiment, as described above, the blade portion 131a is formed into a tapered shape from the downstream side toward the upstream side in the conveying direction A of the belt 32 by the belt conveyor portions 12a and 12b. In addition, the blade portion 131a is configured so that the position at which the top cover tape 322 is cut is shifted from the upstream side to the downstream side in the conveying direction A due to use. In addition, the marking portion 14 is configured so that the life of the blade portion 131a can be identified by comparing it with the position in the conveying direction A at which the top cover tape 322 is cut by the blade portion 131a. Thus, by comparing the position at which the top cover tape 322 is cut by the blade portion 131a with the marking portion 14, the life of the blade portion 131a can be confirmed and the period until the end of the life can be estimated, thereby making it easy to determine the timing of replacing the blade portion 131a.

[0085] In addition, in the present embodiment, as mentioned above, the position of the conveying direction A where the marking portion 14 is cut by the knife portion 131a with respect to the top tape 322 is arranged in a manner to indicate the position of the life of the knife portion 131a. Thus, by comparing the position where the top tape 322 is cut by the knife portion 131a and the marking portion 14, the life of the knife portion 131a can be more easily confirmed.

[0086] In addition, in this embodiment, as described above, the marking portion 14 is provided linearly so as to indicate the position of the life of the blade 131a. Thus, by checking the linear marking portion 14, the life of the blade 131a can be easily checked.

[0087] In addition, in this embodiment, as mentioned above, the marking portion 14 is arranged on the upper surface of the blade portion 131a. Thereby, the marking portion 14 can be easily confirmed from above the blade portion 131a.

[0088] Furthermore, in this embodiment, as described above, the inspection unit 15 is provided. This inspection unit 15 includes an inspection imaging unit 152 that captures images for inspecting the conveying status of the belt 32 of the belt conveyor units 12a and 12b. Furthermore, the inspection unit 15 is configured to use the inspection imaging unit 152 to capture images of the marking portion 14 and the blade 131a, and to confirm the life of the blade 131a based on the captured images. Thus, since the life of the blade 131a is automatically confirmed by the inspection imaging unit 152 capturing the marking portion 14 and the blade 131a, the operator does not need to visually check the marking portion 14. This allows the operator to confirm the life of the blade 131a while minimizing the workload on the operator.

[0089] In addition, in this embodiment, as described above, the inspection unit 15 is configured to issue a notification urging the replacement of the blade 131a when it is determined that the blade 131a has reached its lifespan. Thus, the operator can easily recognize the timing of replacing the blade 131a through the notification of replacement of the blade 131a from the inspection unit 15.

[0090] Furthermore, in this embodiment, as described above, the control unit 8 is configured to use the substrate recognition camera 43 to capture images of the marking portion 14 and the blade 131a, and to check the life of the blade 131a based on the captured images. Thus, since the control unit 8 automatically checks the life of the blade 131a by capturing images of the marking portion 14 and the blade 131a by the substrate recognition camera 43, the operator does not need to visually check the marking portion 14. This allows the operator to check the life of the blade 131a while minimizing the workload on the operator.

[0091] In addition, in this embodiment, as described above, the control unit 8 is configured to: when it is determined that the blade 131a has reached its lifespan, it issues a notification urging the replacement of the blade 131a. Thus, the operator can easily recognize the timing of the replacement of the blade 131a through the notification of the replacement of the blade 131a from the control unit 8.

[0092] Furthermore, in this embodiment, as described above, the control unit 8 is configured to control the substrate recognition camera 43 to image the marking portion 14 based on at least one of the number of times the tape 32 is conveyed by the tape conveying units 12a and 12b of the component supply device 10, the distance the tape 32 is conveyed by the tape conveying units 12a and 12b of the component supply device 10, and an error in the suction of the component 31 from the tape 32 by the mounting head 42. This prevents the substrate recognition camera 43 from excessively capturing the marking portion 14, thereby preventing the component mounting operation time from being increased due to the substrate recognition camera 43 capturing the marking portion 14.

[0093] (Variation)

[0094] It should be noted that the embodiments disclosed herein are illustrative and non-restrictive in all respects. The scope of the present invention is not represented by the description of the above embodiments but by the scope of the claims, and also includes all changes (modifications) within the meaning and scope equivalent to the scope of the claims.

[0095] For example, in the above embodiment, an example of a structure in which a marking portion is arranged on the upper surface of the blade portion is shown, but the present invention is not limited thereto. Figure 9 As shown in the modified example, mark portion 14a is configured on the upper surface of the upper sealing tape guide 131b. Thus, even when the knife portion 131a is inserted into the lower side of the upper sealing tape 322 and the upper sealing tape 322 is cut off, the situation that mark portion 14 is set is different from that of the knife portion 131a. Therefore, mark portion 14a can be reliably confirmed from the top.

[0096] In addition, the above embodiment shows an example of a structure in which the marking portion is provided in a linear shape extending in the width direction of the blade portion, but the present invention is not limited to this. In the present invention, the marking portion can also be provided in a manner extending linearly in the longitudinal direction of the blade portion (the conveying direction of the belt). For example, the marking portion can be provided along the edge of the blade portion, and the condition of the blade portion can be confirmed by the disappearance of the marking portion as the blade portion becomes blunt.

[0097] In addition, in the above embodiment, an example of a structure in which the top band is cut to both sides in the width direction by the knife portion is shown, but the present invention is not limited thereto. In the present invention, a structure in which the top band is cut at one end side in the width direction by the knife portion and cut to one side may also be adopted.

[0098] Furthermore, the present invention may be configured such that a knife provided at the exposed portion is inserted between the top tape and the carrier tape, and the knife is used to cut the adhesive of the top tape, thereby cutting the top tape to one side in the width direction and peeling it from the carrier tape.

[0099] In the above embodiment, a component supply device is arranged at the component supply position, but the present invention is not limited thereto. In the present invention, a tray or the like on which components are placed may be arranged at the component supply position in addition to the component supply device.
