Description

Technical Field

[0001] The present disclosure relates to a component mounting device for mounting components on a substrate and a component supply device provided in the component mounting device for positioning the components at a removal position. Background Art

[0002] Conventionally, component placement devices are known that include a component supply unit (component supply device) and a placement head that picks up components supplied from the component supply unit and places them on a substrate. A tape feeder is often used as the component supply unit. In a tape feeder, a carrier tape containing components is transported along a transport path provided in the main body. This positions the components at a predetermined component removal position.

[0003] In such tape feeders, before the trailing end of the conveyed carrier tape is drawn into the main body, the leading end of a replenishing carrier tape (supplementary tape) is connected to the trailing end of the carrier tape via a connecting tape. This allows components to be replenished. Furthermore, a type of tape feeder known as an automatic loading feeder is also known that can replenish components without the use of a connecting tape. In an automatic loading feeder, if a replenishing tape is pre-inserted into the tape insertion port at the rear end of the main body, the replenishing tape is automatically drawn into the conveying path after the trailing end of the preceding carrier tape is drawn into the conveying path (see, for example, Japanese Patent Application Laid-Open No. 2017-103374). Summary of the Invention

[0004] The first embodiment of the present disclosure relates to a component mounting device comprising a component supply device, a component mounting unit, a storage unit, a work start detection unit, a measuring unit, and a notification unit. The component supply device sets a carrier tape enclosed with components to a state in which the components can be taken out, and positions the components at a take-out position. The component mounting unit takes out the components positioned at the take-out position and mounts them on a substrate. The storage unit stores a work setting time set for a worker's work on the component supply device. The work start detection unit detects a state in which the work can be performed. The measuring unit measures the time from the time when the work start detection unit detects that the work can be performed. The notification unit makes the worker aware that the remaining time of the work setting time is decreasing based on the time measured by the measuring unit.

[0005] The second embodiment of the present disclosure relates to a component loading device having a component supply device, a component loading section, a storage section, a measuring section, and a notification section. The component supply device puts the carrier tape enclosed with the components into a state in which the components can be taken out and positions the components at the taking-out position. The component loading section takes out the components positioned at the taking-out position and loads them onto the substrate. The storage section stores the operation setting time set for the operation performed by the operator on the component supply device. The component supply device includes a main body, a standby section, a belt feed section, and a switching section. A conveying path for the carrier tape is provided in the main body. The standby section puts the replenishing carrier tape on standby. The belt feed section pulls the replenishing carrier tape located in the standby section into the conveying path and feeds it downstream. The switching section selectively switches between a prohibited state and an accommodating state, wherein the replenishing carrier tape is prohibited from being accommodated in the standby section in the prohibited state and the accommodating state is allowed to be accommodated in the standby section in the accommodating state. The measuring section measures the time from when the switching section switches to the accommodating state. The notification unit allows the operator to recognize that the remaining time of the work setting time is decreasing based on the time measured by the measuring unit.

[0006] The first embodiment of the present disclosure relates to a component supply device that places a carrier tape enclosed with components in a state in which the components can be removed, and positions the components at a removal position. The component supply device includes a storage unit, a work start detection unit, a measuring unit, and a notification unit. The storage unit stores a work setting time set for a worker to perform work on the component supply device. The work start detection unit detects a state in which the work can be performed. The measuring unit measures the time from when the work start detection unit detects that the work can be performed. The notification unit notifies the worker that the remaining time of the work setting time is decreasing based on the time measured by the measuring unit.

[0007] The second embodiment of the present disclosure relates to a component supply device that puts a carrier tape enclosed with components into a state in which the components can be taken out, and positions the components at a take-out position. The component supply device includes a storage unit, a main body, a standby unit, a tape feed unit, a switching unit, a measuring unit, and a notification unit. The storage unit stores the operation setting time set for the operation performed by the operator on the component supply device. A conveying path for the carrier tape is provided in the main body. The standby unit puts the replenishing carrier tape on standby. The tape feed unit pulls the replenishing carrier tape located in the standby unit into the conveying path and feeds it downstream. The switching unit selectively switches between a prohibited state and an accommodating state, wherein in the prohibited state, the replenishing carrier tape is prohibited from being accommodated in the standby unit, and in the accommodating state, the replenishing carrier tape is allowed to be accommodated in the standby unit. The measuring unit measures the time from when the switching unit is switched to the accommodating state. Based on the time measured by the measuring unit, the notification unit makes the operator realize that the remaining time of the operation setting time is decreasing.

[0025] [Implementation Method]

[0026] Before describing the embodiments of the present disclosure, the process of arriving at the concept of the present disclosure will be briefly described.

[0027] Automatic loading feeders usually have a switching unit that switches between an accommodating state in which the carrier tape can be accommodated in the main body and a prohibited state in which the carrier tape is prohibited from being accommodated. The switching unit switches from the prohibited state to the accommodating state when the operator performs a given operation, and automatically returns to the prohibited state after a certain period of time has passed. Therefore, the operator must insert the supplementary tape into the tape insertion port within a certain period of time from the time the given operation is performed. However, there are many cases where the operator is unaware of the time limit for inserting the supplementary tape. Therefore, if the operator inserts the supplementary tape slowly, the time limit will be exceeded, and the operator will need to redo the operation. Such redoing will lead to a decrease in productivity.

[0028] The present disclosure provides a component loading device and a component supply device that can prompt workers to work quickly and improve productivity. Various embodiments of the present disclosure are described below with reference to the accompanying drawings. In Embodiments 2 and 3, the same components as in Embodiment 1 are labeled with the same reference numerals, and detailed descriptions may be omitted.

[0029] (Implementation Method 1)

[0030] Figure 1The component mounting system JS includes the component mounting device 1 according to the first embodiment of the present disclosure. The component mounting system JS manufactures a mounting substrate JK by mounting components BH on electrodes DK provided on a substrate KB. The component mounting system JS includes a mounting line 4 and a management computer 5. The mounting line 4 includes a printing device 2, multiple component mounting devices 1, and a reflow soldering device 3, which are arranged in series. The management computer 5 is connected to each device that constitutes the mounting line 4 in a communicative manner.

[0031] Printing device 2 applies paste solder to electrodes DK provided on the surface of substrate KB using screen printing. Component mounting device 1 receives substrate KB from printing device 2 and mounts components BH on the solder-coated electrodes DK. Reflow soldering device 3 receives substrate KB from component mounting device 1 located farthest downstream and reflows the solder to bond components BH to electrodes DK. This creates a mounted substrate JK.

[0032] like Figure 1 as well as Figure 2 As shown, the management computer 5 includes a job instruction unit 5A, a component production changeover information storage unit 5B, and a component replenishment operation support unit 5C. The job instruction unit 5A instructs the printer 2, the plurality of component loading devices 1, and the reflow soldering device 3 on each of these tasks. The component production changeover information storage unit 5B stores component production changeover information, which is information on the production changeover of components BH in each component loading device 1. The component replenishment operation support unit 5C supports component replenishment operations in each component loading device 1. A portable scanner HS is connected to the component replenishment operation support unit 5C via a wired or wireless connection.

[0033] Below, refer to Figure 2 The component loading device 1 will now be described. The component loading device 1 repeatedly performs a component loading operation, loading components BH onto substrates KB that have been loaded from an upstream device (printing device 2 or another component loading device 1) and unloading them downstream. For ease of explanation, the X-axis is defined as an axis within the horizontal plane along the direction in which the substrates KB are transported in the component loading device 1, and the Y-axis is defined as an axis perpendicular to the X-axis within the horizontal plane. Specifically, the X-axis extends from left to right when viewed from the operator OR, and the Y-axis extends from back to front when viewed from the operator OR. Furthermore, the Z-axis is perpendicular to the horizontal plane and extends from bottom to top.

[0034] The component mounting device 1 includes a base 11, a base cover 12, a conveyor 13, a component supply unit 14, a mounting head 15, a head moving mechanism 16, a substrate recognition camera 17, a component recognition camera 18, and a mounting device control unit 19. The base 11 is installed on a floor FL, and the base cover 12 covers the space above the base 11. The conveyor 13 extends along the X-axis within the space on the base 11 covered by the base cover 12. The conveyor 13 carries a substrate KB sent from upstream and positions it at a predetermined work position.

[0035] A feeder cart 21 is connected to the front side of the base 11 (facing the operator OR). The feeder cart 21 has a flat feeder base 22 on top. The component supply unit 14 includes a tape feeder, which is detachably mounted on the feeder base 22.

[0036] A plurality of component supply units 14 can be arranged along the X axis and mounted on the feeder base 22. When the feeder cart 21 is coupled to the base 11, the plurality of component supply units 14 mounted on the feeder base 22 are connected to the base 11 collectively.

[0037] The feeder cart 21 rotatably holds a plurality of reels 32 . A carrier tape 31 enclosing components BH is wound around the reel 32 . The carrier tape 31 drawn from the reel 32 is placed in the corresponding component supply unit 14 .

[0038] like Figure 3A As shown, the carrier tape 31 has a base tape 33 and a top tape 34. Figure 3B As shown in FIG. 1 , a plurality of pockets 35 for storing components, each opening upward, are provided on the base tape 33. The pockets 35 are arranged in a row in the longitudinal direction of the base tape 33 at equal intervals.

[0039] Each pocket 35 of carrier tape 31 holds a component BH. Multiple feed holes 36 are provided in base tape 33, parallel to the rows of pockets 35. These holes 36 are arranged in a row and spaced evenly apart. A top tape 34 is attached to base tape 33 at a position that does not block the feed holes 36, preventing components BH from falling out of pockets 35.

[0040] The component supply unit 14 conveys the carrier tape 31 forward toward the conveyor 13 and positions the pockets 35 sequentially at the take-out position 14K. Figure 4 The carrier tape 31 is conveyed downstream of the conveyance path 41L shown. The top tape 34 is peeled off from the base tape 33 just before the removal position 14K. Therefore, the components BH in the pocket 35 can be removed at the removal position 14K.

[0041] In this manner, each of the component supply units 14 functions as a component supply device that places the carrier tape 31 enclosing the components BH in a state from which the components BH can be taken out, and positions (supplies) the components BH at the take-out position 14K.

[0042] like Figure 2 As shown, the mounting head 15 includes multiple nozzles 15N extending downward. Each nozzle 15N is capable of vertical movement and rotation about the Z axis by a known nozzle drive unit (not shown) built into the mounting head 15. The mounting head 15 picks up components BH positioned at removal positions 14K by the component supply unit 14 by suctioning them to the lower ends of the nozzles 15N. The head moving mechanism 16, for example, includes an XY moving mechanism, and moves the mounting head 15 within a horizontal plane.

[0043] The substrate recognition camera 17 is attached to the mounting head 15. The imaging optical axis of the substrate recognition camera 17 faces downward, and the substrate recognition camera 17 moves together with the mounting head 15 to capture an image of the substrate KB positioned at the working position by the conveyor 13.

[0044] The component recognition camera 18 is installed between the conveyor 13 and the feeder base 22 on the base 11. The optical axis of the component recognition camera 18 faces upward. When the mounting head 15, with each of the plurality of nozzles 15N sucking the component BH, is moved along the X-axis and passes through the area above the component recognition camera 18, the component recognition camera 18 captures the component BH from below.

[0045] The mounting device control unit 19 controls the operation of each unit of the component mounting device 1. The mounting device control unit 19 operates each unit based on pre-stored programs and data to perform a component mounting operation of mounting the component BH on the substrate KB.

[0046] A touch panel 19D is provided on the base cover 12. The touch panel 19D is electrically connected to the mounting device control unit 19. Thus, the mounting device control unit 19 can provide the operator OR with necessary instructions via the touch panel 19D. Furthermore, the operator OR can input necessary instructions and data into the mounting device control unit 19 by operating the touch panel 19D.

[0047] During component loading, the conveyor 13 first operates to receive a substrate KB from upstream and positions it at the work position. Once the substrate KB is positioned at the work position, the head movement mechanism 16 moves the loading head 15 over the substrate KB, and the substrate recognition camera 17 captures the substrate KB. The substrate recognition camera 17 transmits the captured image of the substrate KB to the loading device control unit 19. The loading device control unit 19 recognizes the substrate KB based on the image captured by the substrate recognition camera 17.

[0048] Once the mounting device control unit 19 recognizes the substrate KB, the mounting head 15 repeats the mounting process. During one mounting process, the mounting head 15 sequentially performs the following three actions. The first is to pick up the component BH positioned (supplied) at the removal position 14K by the component supply unit 14. The second is to move the head so that it passes above the component recognition camera 18, allowing the camera 18 to capture an image of the component BH. The third is to place the component BH at a predetermined mounting position on the substrate KB.

[0049] The component recognition camera 18 transmits the image of the component BH captured to the mounting device control unit 19. The mounting device control unit 19 performs component recognition based on the image of the component BH captured by the component recognition camera 18. When the mounting head 15 mounts the component BH on the substrate KB, it corrects the position of the component BH relative to the substrate KB based on the result of the component recognition performed by the mounting device control unit 19.

[0050] As described above, in the present embodiment, the mounting head 15 functions as a component mounting section that takes out the component BH positioned at the take-out position 14K and mounts it on the substrate KB.

[0051] By repeating the above-mentioned mounting process, when all the components BH to be mounted on the substrate KB are mounted, the substrate KB is carried out downstream by the conveyor 13. Thus, the component mounting operation for each substrate KB is completed.

[0052] In the component mounting device 1 having such a structure, the present embodiment has characteristics regarding the structure, operation and control of the component supply unit 14, which will be described below. Figure 4 As shown, the component supply unit 14 has a main body 41, a shutter part 42, a tape feeding part 43, a tape conveying part 44, a cover member 45, a replenishing tape stopper 46, a replenishing tape detection part 47, an operation part 48, a display part 49 and a unit control part 50.

[0053] The main body 41 is provided with a conveyance path 41L for conveying the carrier tape 31. The conveyance path 41L runs from a tape insertion port 41G located at the rear end of the main body 41 (the end facing the operator OR) to a tape discharge port 41H located at the front end of the main body 41. The carrier tape 31 inserted into the tape insertion port 41G is conveyed downstream along the conveyance path 41L and discharged from the tape discharge port 41H. After extending horizontally downstream from the tape insertion port 41G, the conveyance path 41L extends diagonally forward and upward near the center of the front and rear portions of the main body 41. Furthermore, the area at the most front end extends horizontally toward the tape discharge port 41H and is exposed on the upper surface of the main body 41.

[0054] A downwardly protruding engaging portion 41K is provided at the bottom of the main body 41. The main body 41 is attached to the feeder base 22 by engaging the engaging portion 41K with a groove-shaped engaged portion (not shown) provided on the upper surface of the feeder base 22. In this manner, the component supply unit 14 is attached to the feeder base 22.

[0055] The shutter section 42 is provided near the tape insertion port 41G in the main body 41. The shutter section 42 includes a shutter 51 and a shutter drive section 52. The shutter 51 is movable between a closed position and an open position. In the closed position, the lower end of the shutter 51 abuts against the conveying path 41L near the tape insertion port 41G, closing the tape insertion port 41G. When the carrier tape 31 is inserted into the conveying path 41L, the lower end of the shutter 51 abuts against the carrier tape 31. In the open position, the shutter 51 is lifted upward to open the tape insertion port 41G. The shutter drive section 52 is controlled by the unit control section 50 to operate, lift the shutter 51, and arrange it in the open position. In addition, the shutter drive section 52 releases the lifting of the shutter 51 and moves the shutter 51 downward by its own weight or the force of an elastic body (not shown), thereby arranging it in the closed position.

[0056] The tape feed portion 43 is provided at a rear lower portion of the main body portion 41 and downstream of the shutter portion 42. The tape feed portion 43 includes a first sprocket 61, a first drive portion 62, and an encoder 63.

[0057] The first sprocket 61 is connected to the output shaft of the first drive unit 62 via a one-way clutch (not shown). The one-way clutch transmits rotation of the output shaft in the direction of feeding the carrier tape 31 to the first sprocket 61, but does not transmit rotation in the opposite direction. Therefore, when the first drive unit 62 rotates the output shaft in the direction of feeding the carrier tape 31, the first sprocket 61 also rotates in the same direction. Furthermore, when a force in the direction of feeding the carrier tape 31 is applied to the first sprocket 61 while the output shaft is stopped, the first sprocket 61 rotates in that direction.

[0058] The first driving unit 62 is controlled by the unit control unit 50 to operate and rotate the first sprocket 61. The encoder 63 detects the rotation of the first sprocket 61 and transmits the information to the unit control unit 50.

[0059] A tape pressing mechanism 64 is disposed below the tape feed section 43 to press the carrier tape 31 in the conveyance path 41L toward the first sprocket 61. The tape pressing mechanism 64 is constantly biased toward the first sprocket 61 by an elastic member (not shown). The carrier tape 31 inserted through the tape insertion port 41G is inserted between the first sprocket 61 and the tape pressing mechanism 64 while pressing downward on the tape pressing mechanism 64.

[0060] Among the outer peripheral teeth of the first sprocket 61, the outer peripheral tooth located directly below the rotation center of the first sprocket 61 (the lowest outer peripheral tooth) is located within the conveyance path 41L. Therefore, when the first drive unit 62 operates to rotate the first sprocket 61, the lowest outer peripheral tooth of the first sprocket 61 engages with the feed hole 36 of the carrier tape 31, causing it to move downstream. This causes the entire carrier tape 31 to advance downstream.

[0061] Furthermore, when the operator OR inserts the carrier tape 31 from the tape insertion port 41G and the outer peripheral teeth are pressed, the first sprocket 61 rotates. In this state, the first sprocket 61 rotates asynchronously with the operation of the tape conveyor 44. The encoder 63 can detect this state. Based on the detection by the encoder 63, the unit control unit 50 activates the first drive unit 62 to feed the carrier tape 31 downstream of the conveyance path 41L. Thus, the unit control unit 50 conveys the carrier tape 31 until the front end of the inserted carrier tape 31 reaches the replenishing tape stopper 46 or the removal position 14K.

[0062] The first sprocket 61 has a plurality of peripheral teeth that engage with the feed holes 36 of the carrier tape 31. The length of each of these peripheral teeth is less than the thickness of the carrier tape 31. Therefore, below the first sprocket 61, when the replenishing carrier tape 31 overlaps the preceding carrier tape 31, the peripheral teeth engage only with the replenishing tape 31B. Hereinafter, the preceding carrier tape 31 will be referred to as the preceding tape 31A, and the replenishing carrier tape 31 will be referred to as the replenishing tape 31B.

[0063] The belt conveyor 44 is provided at the front upper portion of the main body 41. The belt conveyor 44 includes a second sprocket 71 and a second drive unit 72. The second drive unit 72 is controlled by the unit control unit 50 to operate and rotate the second sprocket 71.

[0064] Among the outer peripheral teeth of the second sprocket 71, the outer peripheral teeth (the uppermost outer peripheral teeth) located just above the rotation center of the second sprocket 71 protrude from the upper surface of the main body 41. Therefore, the outer peripheral teeth of the second sprocket 71 are inserted into the feed holes 36 (see FIG. 3 ) of the carrier tape 31 conveyed by the tape feed unit 43. Figure 3B ). Moreover, if the second driving portion 72 drives the second sprocket 71, and the second sprocket 71 is Figure 4 If the carrier belt 31 rotates clockwise in the middle, it is transported downstream.

[0065] Cover member 45 covers the upper surface of the front end portion of main body 41. A gap of sufficient height for carrier tape 31 to pass is provided between cover member 45 and the upper surface of main body 41. Carrier tape 31 conveyed by tape conveyor 44 passes through this gap and moves downstream.

[0066] The cover member 45 is provided with an exposure portion (not shown) for opening the component storage pocket 35 to expose the stored components BH. The cover member 45 is provided with a component removal port (not shown) above the removal position 14K. Figure 2 The nozzle 15N can suck and remove the component BH positioned at the removal position 14K through the component removal port. The carrier tape 31 (base tape 33 ) passing through the gap between the cover member 45 and the upper surface of the main body 41 is discharged to the outside from the front end of the main body 41 .

[0067] The exposed portion can be a blade, a cutter, or a roller. When a blade is used, the exposed portion peels the top tape 34 from the carrier tape 31 through the gap between the carrier tape 31 and the upper surface of the main body 41. When a cutter is used, the exposed portion cuts the top tape. When a roller is used, the exposed portion pulls the top tape 34 and tears it from the carrier tape 31. The exposed portion does not necessarily need to be provided on the cover member 45; it can also be provided on the main body 41.

[0068] The supplementary belt stopper 46 is located downstream of the bottommost outer peripheral tooth of the first sprocket 61. The operator OR can insert the supplementary belt 31B through the belt insertion port 41G even when the leading belt 31A is present in the conveyance path 41L. In this case, the operator OR can insert the supplementary belt 31B so that it overlaps the upper surface of the leading belt 31A and push it inward while rotating the first sprocket 61.

[0069] When the replenishing tape 31B is pushed in as described above, its front end contacts the replenishing tape stopper 46, placing it in a standby position. The position (location) holding the replenishing tape 31B in this manner is referred to as the standby portion 41T. In this embodiment, the standby portion 41T is located within the conveyance path 41L. However, the standby portion 41T may be located outside the conveyance path 41L as long as it can hold the replenishing tape 31B in a position that allows it to be conveyed downstream of the conveyance path 41L. Furthermore, the tape feed unit 43 pulls the carrier tape 31 located in the standby portion 41T into the conveyance path 41L and feeds it downstream (downstream of the main body 41).

[0070] The replenishing tape detector 47 is located approximately upstream of the replenishing tape stopper 46 (approximately behind the main body 41). Specifically, the replenishing tape detector 47 is located between the bottommost outer peripheral teeth of the first sprocket 61 and the replenishing tape stopper 46. The replenishing tape detector 47 includes a vertically movable detector and a roller located at the lower end of the detector. When the carrier tape 31 advancing within the conveying path 41L abuts against the roller and pushes it upward, the detector and the roller are also pushed upward integrally. The presence of carrier tapes 31 in the standby section 41T and whether there are one or two carrier tapes 31 are detected based on the amount of push-up by the detector (the height of the roller). If the replenishing tape detector 47 detects two carrier tapes 31, this means that the replenishing tape 31B is overlapping the preceding tape 31A.

[0071] The operating portion 48 is provided at the rear upper portion of the main body 41. Figure 5 As shown in FIG, the operation unit 48 includes a plurality of buttons that can be manually operated by the operator OR. The operator OR can input various operation commands by operating the buttons on the operation unit 48.

[0072] like Figure 4 、 Figure 5 As shown, the display unit 49 and the operation unit 48 are provided adjacent to the upper rear portion of the main body 41. Figure 6A As shown, the display unit 49 includes two lighting devices 49D arranged horizontally. The lighting devices 49D each include a 7-segment light emitting diode (LED). Figures 6B to 6F In addition to displaying Arabic numerals as shown, it is also possible to Figure 6G to Figure 6I That way multiple characters (Latin letters) can be displayed.

[0073] exist Figure 4 In the embodiment, a connector 50C is provided at the lower front end of the main body 41. The connector 50C engages with the connector (not shown) of the feeder cart 21. Furthermore, when the feeder cart 21 engages with the connector of the base 11, the connector of the feeder cart 21 and the base 11 are connected in a communicative state. This enables the unit control unit 50 of the component supply unit 14 and the loading device control unit 19 of the component loading device 1 to communicate with each other.

[0074] Figure 7 The control system of the component mounting device 1 including the management computer 5 is shown. The mounting device control unit 19 of the component mounting device 1 is communicatively connected to the unit control unit 50 of each of the plurality of component supply units 14 mounted on the feeder base 22 .

[0075] The unit control unit 50 includes a storage unit 81, a tape storage processing unit 82, a job start detection unit 83, a timer 84, and a remaining time display processing unit 85. The storage unit 81 stores various data required for the component supply unit 14 to transport the carrier tape 31. The data stored in the storage unit 81 includes a tape storage permission flag (hereinafter referred to as a permission flag) 81F and a job set time 81T.

[0076] Permission flag 81F indicates that the component supply unit 14 is in a state where it can accept component replenishment operations by the operator OR. Permission flag 81F is set by the management computer 5 (specifically, the operation instruction unit 5A). The management computer 5 sets permission flag 81F to "1" when the state is set to allow component replenishment operations, and sets permission flag 81F to "0" when the state is set to not accept component replenishment operations. In other words, for component supply units 14 determined to require replenishment of component BH, the management computer 5 sets permission flag 81F to "1," thereby changing the state to accept component replenishment operations by the operator OR. Furthermore, for component supply units 14 that do not require component replenishment operations, even if the operator OR mistakenly requests component replenishment operations, the management computer 5 will not accept the operation.

[0077] Work instruction unit 5A of management computer 5 monitors the remaining amount of components BH on carrier tape 31 (preceding tape 31A) of each of the plurality of component supply units 14 included in component mounting apparatus 1. Work instruction unit 5A sends a command to set permission flag 81F to "1" to the unit control unit 50 of the component supply unit 14 that has determined that the components BH need to be replenished.

[0078] When the replenishment tape 31B is inserted into the tape insertion port 41G of the component supply unit 14 and the component replenishment operation is completed, the operation instruction unit 5A sends a command to set the permission flag 81F to "0" to the unit control unit 50 of the component supply unit 14 in which the replenishment tape 31B is inserted.

[0079] Furthermore, the operation instruction unit 5A has a function of notifying the operator OR of the component replenishment operation for the component supply unit 14 for which the permission flag 81F is set to "1". Specifically, the operation instruction unit 5A notifies the operator OR of the component replenishment operation for the component supply unit 14 for which the permission flag 81F is set to "1". Figure 2 ), a monitor installed in the factory (not shown), a portable terminal carried by an operator OR, etc., notifies the location of the component supply unit 14 to which the component BH to be replenished, the name of the component BH to be replenished, the storage place, etc.

[0080] The operation setting time 81T is the time set by the operator OR for the component supply unit 14. Specifically, the operation setting time 81T is the time from when the shutter 51 of the component supply unit 14 is opened to when it is closed. In other words, it is the time during which the operator OR can insert the replenishment tape 31B from the tape insertion port 41G of the component supply unit 14 (the component replenishment operation). The operation setting time 81T can be set to any value by the operator OP, for example, by inputting it through the operation unit 48. Generally, the operation setting time 81T is set to a value ranging from several seconds to more than ten seconds.

[0081] The tape storage processing unit 82 controls the shutter unit 42, the supplementary tape stopper 46, and the tape feeding unit 43. The tape storage processing unit 82 controls the opening and closing operation of the shutter unit 42 with respect to the tape insertion port 41G. Specifically, the tape storage processing unit 82 switches the shutter 51 by causing the shutter driving unit 52 to perform the lifting operation and the lifting release operation. Figure 4 The tape insertion port 41G is shown in the open and closed positions. Furthermore, the shutter 51 is normally in the closed position, closing the tape insertion port 41G, except for the time set to allow the carrier tape 31 to be inserted through the tape insertion port 41G. In other words, the tape storage processing unit 82 has the function of determining whether or not to allow the carrier tape 31 to be stored in the component supply unit 14.

[0082] When the encoder 63 detects that the carrier tape 31 inserted from the tape insertion port 41G is rotating the first sprocket 61, the tape storage processing unit 82 activates the first drive unit 62 to rotate the first sprocket 61. This causes the carrier tape 31 to be transported downstream. The tape storage processing unit 82 stops the first drive unit 62 based on the following two conditions. The first condition is the number of carrier tapes 31 placed in the standby section 41T due to the insertion of the carrier tape 31. The second condition is the state of the preceding tape 31A on the transport path 41L at the time of the insertion of the carrier tape 31.

[0083] If the supplementary tape detection unit 47 detects the second carrier tape 31, the tape storage processing unit 82 determines that the second carrier tape 31 is in the Figure 4 In the illustrated standby section 41T, the supplementary tape 31B is inserted while the preceding tape 31A is present. When the leading end of the supplementary tape 31B reaches the supplementary tape stopper 46, the tape storage unit 82 stops the first drive unit 62. As a result, the tape storage unit 82 stops the supplementary tape 31B in the standby section 41T.

[0084] On the other hand, if the supplementary tape detection unit 47 detects only one carrier tape, and the trailing end of the preceding tape 31A has passed the standby portion 41T but still exists in the conveyance path 41L, the tape storage unit 82 also determines that the supplementary tape 31B has been inserted. When the trailing end of the supplementary tape 31B reaches the supplementary tape stopper 46, the tape storage unit 82 stops the first drive unit 62. Thus, the tape storage unit 82 stops the supplementary tape 31B in the standby portion 41T. Furthermore, the presence of a carrier tape 31 remaining in the conveyance path 41L can be estimated based on the amount of carrier tape 31 fed by the tape conveyor 44 after the supplementary tape detection unit 47 stops detecting the presence of a carrier tape 31. Alternatively, a sensor (not shown) that detects the presence of a carrier tape 31 may be provided in the conveyance path 41L, and the sensor may detect whether a carrier tape 31 remains in the conveyance path 41L after the trailing end of the preceding tape 31A passes the standby portion 41T.

[0085] Furthermore, if the supplementary tape detection unit 47 detects that there is only one carrier tape 31 and the preceding tape 31A is not present in the conveyance path 41L, the tape storage processing unit 82 determines that the supplementary tape 31B has been inserted without the preceding tape 31A. Furthermore, when the leading end of the supplementary tape 31B reaches a position where it engages with the second sprocket 71 of the tape conveying unit 44, the tape storage processing unit 82 stops the first drive unit 62. Thus, the tape storage processing unit 82 conveys the supplementary tape 31B to the tape conveying unit 44 without stopping the supplementary tape 31B in the standby portion 41T.

[0086] While the supplementary tape 31B is waiting in the standby section 41T, if the supplementary tape detection unit 47 detects that the number of carrier tapes 31 in the standby section 41T has changed from two to one, the tape storage unit 82 releases the supplementary tape stopper 46, allowing the supplementary tape 31B to move downstream. Specifically, if the tape storage unit 82 detects that the terminal end of the preceding tape 31A has passed the position of the supplementary tape detection unit 47, the tape storage unit 82 releases the supplementary tape stopper 46. Furthermore, if the preceding tape 31A moves downstream, the tape storage unit 82 drives the first drive unit 62 to convey the supplementary tape 31B downstream. This causes the supplementary tape 31B to move within the conveyance path 41L, tracking the preceding tape 31A. Furthermore, if the supplementary tape 31B engages with the second sprocket 71 and is conveyed by the tape conveying unit 44, the tape storage unit 82 stops the first drive unit 62.

[0087] Thus, in this embodiment, the tape feed unit 43 has the function of pulling the carrier tape 31 located in the standby portion 41T into the conveyance path 41L and feeding it downstream (in front of the main body 41). In addition, the tape storage processing unit 82 has the function of controlling the conveyance of the carrier tape 31 by the tape feed unit 43.

[0088] The management computer 5 keeps track of the remaining number of components. If the carrier tape 31 (preceding tape 31A) is being transported and the components are running low, and a component supply unit 14 requiring replenishment of components BH is detected, the management computer 5 sets the permission flag 81F to "1" for the unit control unit 50 of the component supply unit 14 requiring replenishment of components BH. Furthermore, the management computer 5 notifies the operator OR of the location of the component supply unit 14 and the components BH to be replenished, as part of the component replenishment operation.

[0089] The operator OR confirms the notified component replenishment operation and finds the position of the component supply unit 14 (hereinafter referred to as the "component replenishment operation target unit") that needs to replenish the component BH. In addition, the operator OR prepares the reel 32 of the carrier tape 31 enclosing the component BH to be replenished. Figure 3A 、 Figure 5 As shown, the operator OR uses the aforementioned portable scanner HS to scan the barcode 32C attached to the side of the prepared reel 32. The operator OR then causes the portable scanner HS to read the information on the prepared component BH. The information on the component BH thus read (referred to as "read component information") is transmitted via the portable scanner HS to the component replenishment support unit 5C of the management computer 5.

[0090] The component replacement adjustment information storage unit 5B of the management computer 5 stores the correspondence between the component name of the component BH and the component supply position on the feeder base 22, as well as information regarding the tape storage capability of the component replenishment target unit mounted at the component supply position (supply component information). When the component replenishment operation support unit 5C receives the component information read by the portable scanner HS, it searches the supply component information using the component name contained in the read component information. Furthermore, the component replenishment operation support unit 5C confirms whether the component name is present in the supply component information and whether the component replenishment target unit mounted at the component supply position corresponding to the component name is in the "tape storage capable state."

[0091] If the component name is included in the supplied component information and the corresponding component replenishment target unit is in the "capable storage state," the component replenishment operation support unit 5C determines that the operator OR has prepared the correct reel 32. Furthermore, the component replenishment operation support unit 5C sends a command to the component replenishment target unit to flash the LED on the display unit 49 as a component replenishment target unit notification command. Upon receiving this command, the component replenishment target unit flashes the LED on the display unit 49 to inform the operator OR of its location.

[0092] Furthermore, upon receiving a signal indicating the start of a component replenishment operation from the component replenishment target unit that issued the instruction to flash the LED, the component replenishment operation support unit 5C transmits a replenishment operation start permission signal. Specifically, upon detecting a signal indicating the start of a component replenishment operation issued by the operator OR operating the operating unit 48, the component replenishment operation support unit 5C transmits the replenishment operation start permission signal. Thus, the component replenishment operation support unit 5C transmits the replenishment operation start permission signal only when the operator OR correctly selects a unit designated as a component replenishment target unit from among the multiple component supply units 14 installed in parallel.

[0093] The operation start detection unit 83 detects that the operator OR has started the operation of replenishing the replenishment tape 31B to the component supply unit 14 (component replenishment operation). The operation start detection unit 83 receives a replenishment operation start permission signal from the component replenishment operation support unit 5C, thereby detecting the start of the component replenishment operation. In this embodiment, the operation start detection unit 83 indirectly detects the start of the component replenishment operation based on the replenishment operation start permission signal from the component replenishment operation support unit 5C, but is not limited to this. The operation start detection unit 83 may also detect the start of the component replenishment operation by directly detecting an operation to start the component replenishment operation on the operating unit 48 of the component replenishment target unit. Alternatively, the operation start detection unit 83 may detect the start of the component replenishment operation by having the shutter drive unit 52 move the shutter 51 to the open position.

[0094] Upon receiving a replenishment operation start permission signal from the component replenishment operation support unit 5C, the unit control unit 50 of the component replenishment target unit activates the shutter drive unit 52 via the tape storage processing unit 82, thereby moving the shutter 51 to the open position. This opens the tape insertion port 41G in the component replenishment target unit (tape storage enabled state), allowing the operator OR to insert the replenishment tape 31B through the tape insertion port 41G.

[0095] Timer 84 measures the time that has elapsed since the start of the component replenishment operation. When the operation start detection unit 83 detects the start of the component replenishment operation, timer 84 begins measuring time. Then, when the aforementioned operation set time 81T stored in storage unit 81 has elapsed, measurement ends. In other words, timer 84 functions as a measuring unit that measures the time that has elapsed since the start of the component replenishment operation.

[0096] The remaining time display processing unit 85 causes the display unit 49 to display the remaining time remaining for the component replenishment operation. Specifically, the remaining time display processing unit 85 calculates the remaining time by subtracting the time measured by the timer 84 from the operation setting time 81T, and causes the display unit 49 to display a number corresponding to the remaining time. In this embodiment, if the remaining time is less than 5 seconds, a countdown is displayed in 1-second increments, such as "4," "3," "2," "1," and "0." Figure 6B → Figure 6C → Figure 6D → Figure 6E → Figure 6F ). In addition to the above-mentioned countdown display, the display unit 49 can also display the countdown display if the supplementary tape 31B is inserted normally. Figure 6H If the operator selects the wrong component supply unit 14, the operator can also Figure 6I The text "ER" indicating an error is displayed as shown.

[0097] Thus, the display unit 49 and the remaining time display processing unit 85 function as a notification unit for notifying the operator OR that the remaining time of the work setting time 81T is decreasing (continuously decreasing) based on the time measured by the timer 84 .

[0098] Next, the operation of the switch 51 will be described. Figure 8A The figure shows a state where the carrier tape 31 (preceding tape 31A) is inserted into the tape insertion port 41G and the shutter 51 closes the tape insertion port 41G. In this state, the operator OR cannot insert the supplementary tape 31B from the tape insertion port 41G and place it in the standby portion 41T (tape storage prohibited state). On the other hand, if the tape 31B is inserted into the tape insertion port 41G and the tape 31B is placed in the standby portion 41T, the operator OR cannot insert the supplementary tape 31B from the tape insertion port 41G and place the tape 31B in the standby portion 41T (tape storage prohibited state). Figure 8B As shown by arrow A1, the tape storage processing unit 82 operates the shutter driving unit 52 to lift the shutter 51, thereby opening the tape insertion port 41G. Therefore, the operator OR can insert the supplementary tape 31B from the tape insertion port 41G and position it in the standby portion 41T (tape storage state).

[0099] After the shutter 51 is opened, the operator OR inserts the supplementary tape 31B from the tape insertion port 41G. Figure 8C As shown, when the front end of the supplementary belt 31B contacts the supplementary belt stopper 46, the belt storage processing unit 82 controls the shutter driving unit 52 to release the lifting of the shutter 51. Figure 8D As shown by arrow A2, shutter 51 descends (falls down), and tape insertion port 41G is closed. As a result, insertion of carrier tapes 31 above this is prohibited (prohibited state).

[0100] Thus, in this embodiment, the shutter unit 42 (the shutter 51 and the shutter driving unit 52) and the tape storage processing unit 82 serve as Figure 7 The switching unit 90 shown in FIG. 4 selectively switches between a prohibited state in which the carrier tape 31 (replenishing tape 31B) is prohibited from being stored in the standby unit 41T and a storage-enabled state in which the carrier tape 31 is allowed to be stored in the standby unit 41T.

[0101] Below, refer to Figure 9 The flow of the component replenishment operation performed by the operator OR will be described along with changes in the display content displayed on the display unit 49 of the component supply unit 14 that is the target of the component replenishment operation.

[0102] The operator OR first confirms the details of the component replenishment operation notified by the operation instruction unit 5A using the touch panel 19D of the component loading device 1, a factory monitor, a portable terminal, or the like. The operator OR then prepares a reel 32 containing the component BH to be replenished and determines the position of the component replenishment target unit on the feeder base 22. The operator OR then inputs component information by reading the barcode 32C on the reel 32 with the portable scanner HS (step ST1). The portable scanner HS transmits the read component BH information (read component information) to the component replenishment operation support unit 5C.

[0103] The component replenishment operation support unit 5C confirms whether the component BH identified by the received read component information is the target of the component replenishment operation notified by the operation instruction unit 5A (step ST2). Specifically, the component replenishment operation support unit 5C uses the component name contained in the read component information to search the supply component information stored in the component replacement adjustment information storage unit 5B. If the component name is included in the supply component information and the component replenishment target unit mounted at the component supply position corresponding to the component name is in the "capable storage state," the component replenishment operation support unit 5C sends a component replenishment unit notification command to the unit control unit 50 of the component replenishment target unit. Upon receipt of the component replenishment target unit notification command, the unit control unit 50 flashes the LED on the display unit 49 to notify the operator OR of the unit's location (step ST3).

[0104] When the LED on the display unit 49 of the component supply unit to be replenished begins flashing, the operator OR operates the operating unit 48 of the component supply unit 14 whose LED is flashing. In other words, the operator OR selects a component supply unit to be replenished from the plurality of component supply units 14 arranged on the feeder base 22 (step ST4). When the operator OR selects a component supply unit 14 and operates the operating unit 48, identification information of the selected component supply unit 14 is transmitted to the component replenishment operation support unit 5C of the management computer 5.

[0105] The component replenishment operation support unit 5C checks whether the component supply unit 14 that sent the component replenishment target unit notification command in step ST2 and the component supply unit 14 that sent the identification information in step ST4 are the same (step ST5). If they are not the same, the component replenishment operation support unit 5C sends an error to the component supply unit 14 whose identification information was sent due to the operator OR's mistaken selection. Then, the unit control unit 50 of the component supply unit 14 that received the error is as follows: Figure 6I As shown, the display unit 49 displays the characters "ER" to notify the error (step ST6), and the process returns to step ST4.

[0106] On the other hand, if the match is found, the component replenishment operation support section 5C sends a replenishment operation start permission signal to the unit control section 50 of the component replenishment target unit. Then, the tape storage processing section 82 of the component replenishment target unit that has received the component operation start permission signal causes the shutter driving section 52 to open the shutter 51 and causes the display section 49 of the same component supply unit 14 to display the same component supply unit 14. Figure 6G The characters "OP" are displayed as shown (step ST7).

[0107] At the same time, if the start of the component replenishment operation is detected by receiving a replenishment operation start permission signal, the operation start detection unit 83 starts timing using the timer 84. The remaining time display processing unit 85 measures the remaining time of the operation set time 81T based on the elapsed time measured by the timer 84. As the remaining time decreases, the remaining time display processing unit 85 causes the display unit 49 to count down the remaining time, such as "4" → "3" → "2" → "1" → "0" (step ST8). This allows the operator OR to recognize the remaining time for the component replenishment operation, prompting them to work quickly.

[0108] If the text "OP" is displayed on the display unit 49 of the component replenishment target unit in step ST7, the operator OR visually confirms the display (step ST9). Then, the operator OR inserts the replenishment tape 31B pulled out from the reel 32 whose barcode has been read into the tape insertion port 41G of the component replenishment target unit (step ST10). If the replenishment tape detection unit 47 of the component replenishment target unit detects that the operator OR has inserted the replenishment tape 31B, the unit control unit 50 of the component replenishment target unit controls the operation as follows: Figure 6HAs shown, the display unit 49 displays the word "On" (step ST11). As described above, this display indicates that the replenishment tape 31B has been properly replenished. The operator OR then displays "On" on the display unit 49 of the component supply unit 14 into which the replenishment tape 31B has been inserted, confirming that the replenishment tape 31B is stored in the component supply unit 14 (step ST12). This completes the series of component replenishment operations.

[0109] The component replenishment operation support unit 5C determines that the operator OR has mistakenly selected the component BH to be replenished and does not output a replenishment operation start permission signal in any of the following situations. Specifically, if the component name included in the component information read in step ST2 is not included in the supplied component information, or if the component name is included in the supplied component information but the component supply unit 14 corresponding to the component name is not in the "tape storage state." Consequently, the shutter 51 of any component supply unit 14 does not move to the open position, preventing the replenishment tape 31B from being positioned in the standby section 41T. This prevents the operator OR from mistakenly replenishing the replenishment tape 31B to another component supply unit 14.

[0110] Figure 10 Shown with Figure 9 The process flow described in accords with the flow of the unit control section 50 for storing the replenishment tape 31B. Figure 7 The tape storage processing unit 82 shown first waits for a replenishment operation start permission signal to be transmitted. In other words, it waits for the operation to start (step ST21). Then, upon receiving a replenishment operation start permission signal from the management computer 5 and confirming the start of the operation (step ST22), the tape storage processing unit 82 activates the shutter drive unit 52 to move the shutter 51 to the open position. In other words, the tape storage processing unit 82 transitions the replenishment target unit to a tape storage-capable state (step ST23).

[0111] Furthermore, if the start of the component replenishment operation is detected by receiving the replenishment operation start permission signal, the operation start detection unit 83 controls the timer 84 to start measuring the operation setting time 81T (step ST24). Then, if the shutter 51 is opened, the tape storage processing unit 82 causes the display unit 49 to display the following information: Figure 6G The characters "OP" are displayed (step ST25). The characters "OP" indicate that the replenishment tape 31B can be accommodated.

[0112] Once time measurement by the timer 84 begins, the remaining time display processing unit 85 of the component replenishment target unit measures the remaining time. As the remaining time decreases, the remaining time display processing unit 85 displays a countdown on the display unit 49, such as "4" → "3" → "2" → "1" → "0" (step ST26). Furthermore, when the remaining time reaches zero, the tape storage processing unit 82 activates the shutter drive unit 52 to close the shutter 51, shifting the state to a state where the replenishment tape 31B cannot be stored (step ST27).

[0113] If the state is changed to the storage prohibition state of the supplementary tape, the tape storage processing unit 82 controls the timer 84 to stop and reset the time measurement (step ST28), and the display of the display unit 49 is as follows: Figure 6A When the shutter 51 is closed and the display unit 49 is turned off, the operator OR only needs to open the shutter 51 again. Figure 9 Alternatively, in step ST29 , instead of turning off the display on the display unit 49 , the display may be changed (switched) to a display indicating the operating state of the component supply unit 14 at that time.

[0114] If the operator OR inserts the supplementary tape 31B through the tape insertion port 41G between the time the shutter 51 is opened in step ST23 and the time the shutter 51 is closed in step ST27, the supplementary tape detection unit 47 detects the supplementary tape 31B (step ST30). In this case, the interruption process begins at that point. During the interruption process, the unit control unit 50 closes the shutter 51, transitioning to the tape storage prohibited state (step ST31). Consequently, after the supplementary tape 31B, further insertion of the carrier tape 31 through the tape insertion port 41G is prohibited.

[0115] Furthermore, in step ST31, the tape storage processing unit 82 sets the permission flag 81F to "0" and notifies the setting change of the permission flag 81F to the mounting device control unit 19. This also notifies the component mounting device 1 and the management computer 5 (the operation instruction unit 5A) that the component replenishment operation has been completed.

[0116] If the tape storage prohibition state is changed in step ST31, the tape storage processing unit 82 controls the timer 84 to stop and reset the time measurement (step ST32). Figure 6HAs shown, the display unit 49 displays the text "On" indicating that the replenishment tape 31B has been inserted normally (step ST33). Then, when a predetermined time has elapsed (step ST34), the interrupt process ends and the process proceeds to the aforementioned step ST29. The display unit 49 of the component replenishment target unit is turned off, and the series of processes ends. Furthermore, in step ST34, the unit control unit 50A manages the passage of time.

[0117] Thus, in this embodiment, the component mounting device 1 includes a storage unit 81, a work start detection unit 83, a timer 84, and a notification unit (a display unit 49 and a remaining time display processing unit 85). The storage unit 81 stores the work setting time 81T set for the work performed by the operator OR on the component supply unit 14. The work performed by the operator OR on the component supply unit 14 is the work of inserting the replenishment tape 31B and placing it on standby in the standby unit 41T. The work start detection unit 83 detects the state in which the work can be performed (the work-ready state). The timer 84, serving as a measuring unit, measures the elapsed time since the work start detection unit 83 detected the state in which the work can be performed. Based on the time measured by the timer 84, the notification unit notifies the operator OR that the remaining time in the work setting time 81T is decreasing (continuously decreasing). The component supply unit 14 also includes a switching unit 90. The switching unit 90 selectively switches between a prohibited state and a storage-enabled state. In the prohibited state, the carrier tape 31 (supplementary tape 31B) is prohibited from being stored in the standby section 41T, where the supplementary tape 31B is waiting. In the storage-enabled state, the supplementary tape 31B is permitted to be stored in the standby section 41T. If work is possible, the switching unit 90 switches to the storage-enabled state. The timer 84 measures the time elapsed since the switching unit 90 switched to the storage-enabled state. In the above description, the timer 84 measures the time elapsed since the state became operational. However, the time required for step ST23 is extremely short, so it can be said that the timer 84 essentially measures the time elapsed since the switching unit 90 switched to the storage-enabled state. The notification unit displays the remaining time of the operation setting time 81T on the display unit 49 based on the time measured by the timer 84, thereby notifying the operator OR that the remaining time is decreasing.

[0118] Therefore, the operator OR strives to complete the work before the remaining time runs out, resulting in a reduction in the number of times the work needs to be redone, thereby improving productivity. In this way, according to the component mounting device 1 of this embodiment, the operator OR can be encouraged to work quickly and the working efficiency of the component mounting device 1 can be improved.

[0119] In the above description, the storage unit 81, timer 84, and display unit 49 are all provided in the component supply unit 14. However, some or all of the storage unit 81, timer 84, and display unit 49 may be provided external to the component supply unit 14 (e.g., in the management computer 5). In particular, the display unit 49 (notification unit) may be provided on the feeder base 22, which serves as the mounting unit on which the component supply unit 14 is mounted, or on the cover (base cover 12) that covers the upper portion of the component supply unit 14. Alternatively, the touch panel 19D provided on the base cover 12 may be used as the display unit 49.

[0120] (Implementation Method 2)

[0121] Next, a second embodiment of the present disclosure will be described. The component mounting device 1 of this embodiment differs from the component mounting device 1 of the first embodiment only in the following points. Specifically, the conditions for detecting the start of a component replenishment operation by the operation start detection unit 83 of the component supply unit 14 and the operation procedure of the operator OR for switching the component supply unit 14 to the belt storage state differ from those of the first embodiment. Other aspects are the same as those of the first embodiment.

[0122] Below, refer to Figure 11 , the flow of the component replenishment operation performed by the operator OR on the component supply unit 14 in this embodiment will be described along with changes in the display content displayed on the display unit 49. Figure 11 Corresponding to the embodiment 1 Figure 9 The same step numbers are marked for common control contents. Figure 10 The supplementary tape storage process described above is also the same as that of the first embodiment except for step ST23.

[0123] In this embodiment, the conditions under which the work start detection unit 83 detects the start of a component replenishment operation differ from those in Embodiment 1. In Embodiment 1, the work start detection unit 83 detects the start of a component replenishment operation through two steps: input of component information (step ST1) and selection of a component replenishment target unit (step ST4). In contrast, in this embodiment, the work start detection unit 83 detects the start of a component replenishment operation solely through input of component information (step ST1). This reduces the workload of the operator OR and improves efficiency. Specifically, the work start detection unit 83 in this embodiment detects the start of a component replenishment operation when the unit control unit 50 receives a component replenishment target unit notification command.

[0124] like Figure 11As shown, in this embodiment, similarly to embodiment 1, the component information is read in step ST1. Moreover, when the component name contained in the read component information is appropriate and the corresponding component supplement object unit is in the "belt capable of accommodating state", the component supplement operation support unit 5C sends a component supplement object unit notification instruction to the unit control unit 50 of the component supplement object unit (step ST2). That is, unlike embodiment 1, it is not determined whether the component supplement object unit selected by the operator OP and the component supplement object unit indicated by the component supplement object unit notification instruction are consistent. If the component supplement object unit notification instruction is received, the belt accommodating processing unit 82 of the component supplement object unit causes the component supplement object unit to transition to the supplement belt capable of accommodating state, and causes the display unit 49 to display as shown. Figure 6G The text "OP" shown in FIG. 7 is shown in FIG. 7 (step ST7). Figure 11 Steps ST8 to ST12 after step ST7 are the same as those in the first embodiment.

[0125] Below, citing Figure 10 The following describes step ST23', which differs from the first embodiment, regarding the replenishment tape storage process. In step ST23 of the first embodiment, upon receiving a replenishment operation start permission signal from the management computer 5, the tape storage processing unit 82 activates the shutter driver 52. Conversely, in step ST23', upon receiving a component replenishment target unit notification command, the tape storage processing unit 82 activates the shutter driver 52. The remaining steps are the same as those of the first embodiment.

[0126] This embodiment also achieves the same effects as in the first embodiment. Furthermore, this embodiment eliminates the need for the steps ST3 to ST6, including step ST4, in which the operator OR selects the component supply unit 14 in the first embodiment. Consequently, the overall number of man-hours required for the operator OR can be reduced.

[0127] (Implementation Method 3)

[0128] Next, the third embodiment of the present disclosure will be described. The component mounting device 1 in this embodiment differs from the component mounting device 1 in the first embodiment only in the structure of the storage portion of the replenishment tape 31B in the component supply unit 14 and the portion related to the control of its operation. That is, the component mounting device 1 in this embodiment has a component supply unit 14 instead of a component supply unit 14. Figure 12 The component supply unit 14A shown is the same as that of the first embodiment except for the above.

[0129] like Figure 12As shown, the component supply unit 14A does not include the shutter portion 42 , the replenishing tape stopper 46 , and the replenishing tape detection portion 47 of the first embodiment, but instead includes a tape insertion guide 91 , a tape insertion detection portion 92 , and a locking mechanism 93 .

[0130] The tape insertion guide 91 is located above an area (referred to as the guide lower area 41R) located at the rearmost portion of the main body 41 within the conveyance path 41L of the main body 41. Specifically, the tape insertion guide 91 is located between the tape insertion port 41G and the lowermost outer peripheral teeth of the first sprocket 61, and above the conveyance path 41L. The tape insertion guide 91 comprises a pair of left and right members that support the lower surfaces of both sides of the carrier tape 31 inserted through the tape insertion port 41G. When the operator OR inserts the carrier tape 31 into the conveyance path 41L, the tape insertion guide 91 supports and guides both sides of the inserted carrier tape 31 from below.

[0131] As described above, the tape insertion guide 91 includes a pair of left and right members. Therefore, after the operator OP causes the carrier tape 31 inserted from the tape insertion port 41G through the tape insertion guide 91 to enter the position to be conveyed by the first sprocket 61, if Figure 14A As shown by the arrow P in FIG, the manual pull downward can be moved to the guide lower area 41R. Figure 14B As shown, the tape insertion guide 91 can be placed in an idle state, and the supplementary tape 31B can be inserted after the preceding tape 31A via the tape insertion guide 91 .

[0132] like Figure 12 as well as Figure 14A 、 Figure 14B As shown, the tape insertion detection unit 92 is provided opposite to the tape insertion guide 91. The tape insertion detection unit 92 detects the carrier tape 31 inserted from the tape insertion port 41G via the tape insertion guide 91, and transmits information indicating that the carrier tape 31 has been inserted from the tape insertion port 41G to the unit control unit 50A. Figure 14B When the preceding tape 31A is pulled down onto the guide lower region 41R as shown, the tape insertion detecting portion 92 cannot detect the preceding tape 31A.

[0133] The lock mechanism 93 prevents the first sprocket 61 from being rotated by being pressed by the supplementary tape 31B inserted into the conveyance path 41L along the tape insertion guide 91 . Figure 13 The control system of the component mounting device 1 according to this embodiment including the management computer 5 is shown. The tape storage processing unit 82 of the unit control unit 50A switches the lock mechanism 93 between a state of preventing the rotation of the first sprocket 61 and a state of allowing the rotation.

[0134] When the management computer 5 transmits a signal permitting the start of a replenishment operation, the tape storage processing unit 82 switches the locking mechanism 93 from a state preventing the rotation of the first sprocket 61 to a state permitting rotation. This switches the component supply unit 14A to a state enabling tape storage. Furthermore, when the tape insertion detection unit 92 detects from the tape insertion guide 91 (standby unit 41T) that there is no replenishment tape 31B, the unit control unit 50A switches the locking mechanism 93 to a state preventing the rotation of the first sprocket 61. This switches the component supply unit 14A to a state preventing tape storage, preventing the component supply unit 14A from storing the tape even if an operator OR mistakenly places the carrier tape 31.

[0135] If the supplementary tape 31B is inserted into the tape insertion guide 91 of the component supply unit 14A in the tape storage state, the tape insertion detection unit 92 detects the insertion of the supplementary tape 31B. Furthermore, if the supplementary tape 31B rotates the first sprocket 61, the encoder 63 detects this. In this case, the tape storage processing unit 82 operates the first driving unit 62 to rotate the first sprocket 61 by a predetermined amount. As a result, the supplementary tape 31B is inserted into the tape insertion guide 91 of the component supply unit 14A in the tape storage state. Figure 12 As shown, it is pulled into the standby portion 41T.

[0136] On the other hand, in the tape storage prohibited state, even if the leading end of the carrier tape 31 inserted through the tape insertion port 41G reaches the first sprocket 61, the locking mechanism 93 prevents the first sprocket 61 from rotating. Consequently, the encoder 63 does not respond, and the first drive unit 62 does not activate. Consequently, the carrier tape 31 is not placed in the standby unit 41T. This prevents the inserted carrier tape 31 from being accidentally pulled into the standby unit 41T.

[0137] Thus, the component supply unit 14A does not have a mechanism corresponding to the shutter portion 42 that can mechanically prevent the carrier tape 31 from being inserted from the tape insertion port 41G, as in the component supply unit 14 of the first embodiment. However, by preventing the first sprocket 61 from rotating, the same effect as that of the shutter portion 42 can be obtained for the carrier tape 31 inserted from the tape insertion port 41G. In this case, the tape insertion detection portion 92, the locking mechanism 93, the tape feeding portion 43, and the unit control portion 50A are configured as follows. Figure 13 As shown, the switching unit 90A functions as the switching unit 90A. The switching unit 90A selectively switches between a prohibition state in which the carrier tape 31 is prohibited from being stored in the standby unit 41T and a storage state in which the carrier tape 31 is permitted to be stored in the standby unit 41T.

[0138] In addition, regarding the supplementary tape storage process, except for the processes of step ST23, step ST27 and step ST31, Figure 10 Same. Below, citing Figure 10 These steps are explained.

[0139] First, step ST23" of this embodiment will be described. When a replenishment operation permission signal is transmitted from the management computer 5 (step ST22), the tape storage processing unit 82 switches the locking mechanism 93 from a state that prevents the rotation of the first sprocket 61 to a state that permits rotation. As a result, the component replenishment target unit is transitioned to a state in which the tape can be stored.

[0140] Next, step ST27' of the embodiment will be described. In the first embodiment, when the remaining time reaches zero, the tape storage processing unit 82 closes the shutter 51, shifting the component replenishment target unit to the tape storage prohibited state. In the present embodiment, the tape storage processing unit 82 switches the locking mechanism 93 to a state that prevents the rotation of the first sprocket 61. This causes the component replenishment target unit to enter the tape storage prohibited state.

[0141] Finally, step ST31' of the present embodiment will be described. Between step ST23" and step ST27', if the supplementary belt detection unit 47 detects that the operator OR has inserted the supplementary belt 31B from the belt insertion port 41G (step ST30), the interruption process starts at that point in time. During the interruption process, the unit control unit 50A operates the first drive unit 62 to rotate the first sprocket 61 only a given amount. As a result, the supplementary belt 31B is placed in the standby portion 41T. Furthermore, if the belt insertion detection unit 92 detects from the belt insertion guide 91 (standby position portion 41T) that there is no supplementary belt 31B, the unit control unit 50A switches the locking mechanism 93 to a state that prevents the rotation of the first sprocket 61 (step ST31').

[0142] In this embodiment, as in the case of embodiment 1, the remaining time display processing unit 85 causes the display unit 49 to display a countdown such as "4" → "3" → "2" → "1" → "0" according to the remaining time of the operation setting time 81T, and displays (notifies) the remaining time for the operator OR to perform the parts replenishment operation, thereby prompting the operator OR to work quickly.

[0143] Thus, in this embodiment, the component supply unit 14A also includes a switching unit 90A. The switching unit 90A selectively switches between a prohibited state and a storage-enabled state. In the prohibited state, the carrier tape 31 is prohibited from being stored in the standby section 41T where the supplementary tape 31B is waiting. In the storage-enabled state, the supplementary tape 31B is permitted to be stored in the standby section 41T. The timer 84, serving as a measuring unit, measures the elapsed time since the storage-enabled state was reached. The remaining time display processing unit 85 and the display unit 49, serving as notification units, notify (display) the operator OR that the remaining time of the operation setting time 81T is decreasing (continuously decreasing) based on the time measured by the timer 84. In other words, the notification unit informs the operator OR that the remaining time is decreasing. This, as in the first embodiment, can encourage the operator OR to work quickly, thereby improving the operating efficiency of the component loading device 1 and achieving the same effects as in the first embodiment.

[0144] So far, the embodiments of the present disclosure have been described, but the present disclosure is not limited to the above contents and can be modified in various ways. For example, in the first embodiment, the replenishing tape detection unit 47 detects the insertion of the replenishing tape 31B into the tape insertion port 41G. Alternatively, the tape insertion detection unit 92 in the third embodiment may be provided in the component supply unit 14, and the replenishing tape 31B may be detected by the tape insertion detection unit 92. In addition, the operation start detection unit 83 indirectly detects the start of the component replenishing operation based on the replenishing operation start permission signal from the component replenishing operation support unit 5C. Alternatively, the operation start detection unit 83 may detect the start of the component replenishing operation by directly detecting that the operation unit 48 of the component replenishing object unit has been operated to start the component replenishing operation. In addition, in the third embodiment, the operation start detection unit 83 may detect the start of the component replenishing operation by detecting the switching of the locking mechanism 93 from the state of preventing the rotation of the first sprocket 61 to the state of allowing the rotation.

[0145] Furthermore, in Embodiments 1-3, the display unit 49 includes lighting (LED lighting) that displays the remaining time of the task set timer 81T. Alternatively, the display unit 49 may simply notify the operator OR that the remaining time of the task set timer 81T is decreasing based on the time measured by the timer 84, and is not limited to the above example. For example, the display unit 49 may notify the operator OR that the remaining time is decreasing by switching from a lit state to a flashing state, changing the flashing cycle according to the remaining time, changing the light color according to the remaining time, or a combination thereof.

[0146] Furthermore, in Embodiments 1 to 3, in step ST1 in which the operator OR inputs the information of the component BH into the component replenishment target unit, the operator OR reads the barcode 32C using a portable scanner HS. However, this is merely an example, and other methods may be used. For example, the information of the component BH may be read from an information tag other than the barcode 32C, such as a wireless tag, or the information of the component BH may be read by photographing the information tag with a camera or the like.

[0147] According to the present disclosure, it is possible to provide a component mounting device and a component supply device that can prompt workers to work quickly and improve productivity.
