Description

The present invention relates to a component mounting device for mounting components on a substrate and a component supplying device provided in the component mounting device to supply components.

Conventionally, there is known a component mounting device that picks up components supplied from a component supply unit (component supply device) by a mounting head and mounts them on a board. As a component supply unit of a component mounting device, a tape feeder that positions a component at a predetermined component take-out position by transporting a carrier tape containing the component on a transport path formed in a main body is often used.

In such a tape feeder, the tip of the carrier tape for replenishment (replenishment tape) is connected to the end of the carrier tape by a connecting tape before the end of the carrier tape to be conveyed is pulled into the main body. As a result, parts can be replenished. There is also known a type of tape feeder called an autoload feeder that can replenish parts without using a connecting tape. When the replenishment tape is inserted into the tape insertion slot at the rear end of the main body of the auto load feeder, the replenishment tape is automatically inserted into the transport path after the end of the preceding carrier tape is pulled into the transport path. (For example, see Patent Document 1 below).

It is provided with a component setup information storage unit 5B and a component replenishment work support unit 5C that supports component replenishment work in each component mounting device 1 (see also FIG. 2). A handy scanner HS is connected to the parts replenishment work support unit 5C by wire or wirelessly.

Here, the component mounting device 1 will be described with reference to FIG. The component mounting device 1 repeatedly executes the component mounting operation of mounting the component BH on the board KB carried in from the device located on the upstream side (printing device 2 or other component mounting device 1) and carrying it out to the downstream side. Here, for convenience of explanation, the transport direction of the substrate KB in the component mounting device 1 (the left-right direction seen from the worker OR) is set to the X-axis direction, and the horizontal direction orthogonal to the X-axis direction (the front-back direction seen from the worker OR). Is the Y-axis direction. Further, the vertical direction is the Z-axis direction.

In FIG. 2, the component mounting device 1 includes a base 11, a base cover 12, a board transfer conveyor 13, a parts supply unit 14, a mounting head 15, a head moving mechanism 16, a board recognition camera 17, a parts recognition camera 18, and a mounting device. A control unit 19 is provided. The base 11 is installed on the floor surface FL, and the base cover 12 is provided so as to cover the space above the base 11. The substrate transfer conveyor 13 is provided so as to extend in the X-axis direction in the space covered by the base cover 12 on the base 11. The board transfer conveyor 13 carries in the board KB sent from the upstream side and then positions it at a predetermined working position.

In FIG. 2, the feeder carriage 21 is connected to the front side (worker OR side) of the base 11. The feeder carriage 21 is provided with a flat plate-shaped feeder base 22 at the top. The component supply unit 14 is composed of a tape feeder, and is detachably attached to a feeder base 22.

A plurality of component supply units 14 can be mounted side by side in the X-axis direction on the feeder base 22. When the feeder carriage 21 is connected to the base 11, a plurality of component supply units 14 attached to the feeder base 22 are collectively connected to the base 11.

In FIG. 2, the feeder carriage 21 is rotatably held by a reel 32 around which a carrier tape 31 containing a component BH is wound. The carrier tape 31 drawn from each reel 32 is attached to the corresponding component supply unit 14.

As shown in FIGS. 3A and 3B, the carrier tape 31 includes a base tape 33 and a top tape 34. The base tape 33 is provided with pockets 35 for storing a large number of parts opened upward in a row and at equal intervals in the longitudinal direction of the base tape 33.

One component BH is stored in each pocket 35 of the carrier tape 31. A plurality of feed holes 36 are provided in a row and at equal intervals at positions parallel to the row of pockets 35 of the base tape 33. The top tape 34 is attached at a position where the feed hole 36 on the upper surface of the base tape 33 is not blocked (FIG. 3B), and prevents the component BH from falling out from each pocket 35.

The component supply unit 14 conveys the carrier tape 31 forward (in the direction toward the substrate transfer conveyor 13), that is, downstream of the transfer path 41L, and sequentially positions each pocket 35 at the component take-out position 14K. The top tape 34 is peeled off from the base tape 33 on the front side of the component take-out position 14K. Therefore, the component BH in each pocket 35 can be taken out at the part take-out position 14K.

As described above, in the present embodiment, each component supply unit 14 is a component supply device that positions (supplies) the carrier tape 31 in which the component BH is enclosed at the component take-out position 14K so that the component BH can be taken out. ing.

In FIG. 2, the mounting head 15 includes a plurality of nozzles 15N extending downward. Each nozzle 15N can move up and down with respect to the mounting head 15 and rotate around the Z axis. The mounting head 15 picks up the component BH positioned by the component supply unit 14 at the component take-out position 14K by attracting the component BH to the lower end of each nozzle 15N. The head moving mechanism 16 is composed of, for example, an XY moving mechanism, and moves the mounting head 15 in the horizontal direction and in the vertical direction.

In FIG. 2, the substrate recognition camera 17 is attached to the mounting head 15. The substrate recognition camera 17 has the image pickup optical axis directed downward, and by moving together with the mounting head 15, the substrate KB is imaged at the working position by the substrate transfer conveyor 13.

In FIG. 2, the component recognition camera 18 is provided in the area between the substrate transfer conveyor 13 and the feeder base 22 on the base 11. When the component recognition camera 18 has the image pickup optical axis directed upward and the mounting head 15 having the component BH adsorbed on each of the plurality of nozzles 15N moves so as to pass through the upper region of the component recognition camera 18 in the X-axis direction. , Each component BH is imaged from below.

The mounting device control unit 19 controls the operation of each unit included in the component mounting device 1. The mounting device control unit 19 executes a component mounting operation for mounting the component BH on the board KB by operating each unit based on a program and data stored in advance.

In FIG. 2, the base cover 12 is provided with the touch panel 19D. The touch panel 19D is connected to the on-board device control unit 19. Therefore, the on-board device control unit 19 can give a required instruction to the operator OR through the touch panel 19D. Further, the operator OR can perform the required input to the on-board device control unit 19 by operating from the touch panel 19D.

In the component mounting work, the board transfer conveyor 13 first operates, receives the board KB sent from the upstream side, and positions it at the work position. When the board KB is positioned at the working position, the head moving mechanism 16 moves the mounting head 15 above the board KB, and causes the board recognition camera 17 to take an image of the board KB. The image of the board KB captured by the board recognition camera 17 is sent to the on-board device control unit 19. The on-board device control unit 19 recognizes the board KB based on the image captured by the board recognition camera 17.

When the mounting device control unit 19 recognizes the board KB, the mounting head 15 repeatedly executes the mounting turn. In one mounting turn, the mounting head 15 moves so that the component supply unit 14 picks up the component BH positioned (supplied) at the component take-out position 14K and passes above the component recognition camera 18 in the X-axis direction. The operation of causing the component recognition camera 18 to image the component BH and the operation of mounting the component BH at the component mounting position defined on the board KB are performed in this order.

The image of the component BH captured by the component recognition camera 18 is sent to the on-board device control unit 19. The on-board device control unit 19 performs component recognition based on the image of the component BH captured by the component recognition camera 18. When the component BH is mounted on the board KB, the mounting head 15 corrects the position of the component BH with respect to the board KB based on the result of the component recognition performed by the mounting device control unit 19.

As described above, in the first embodiment, the mounting head 15 is a component mounting portion that takes out the component BH positioned at the component take-out position 14K and mounts the component BH on the board KB.

When all the component BHs to be mounted on the board KB are mounted by repeatedly executing the above mounting turns, the board transfer conveyor 13 carries out the board KB to the downstream side. This completes the component mounting work for each board KB.

In the component mounting device 1 having such a configuration, in the first embodiment, the configuration, operation, and control of the component supply unit 14 are characterized, and the description thereof will be described below. As shown in FIG. 4, the component supply unit 14 includes a main body 41, a shutter 42, a tape feed 43, a tape transport 44, a cover member 45, a replenishment tape stopper 46, a replenishment tape detection unit 47, and an operation unit 48. It includes a display unit 49 and a unit control unit 50.

In FIG. 4, a transport path 41L for the carrier tape 31 is formed in the main body 41. The transport path 41L has a tape insertion port 41G (see also FIG. 5) provided at the rear end of the main body 41 (the end on the worker OR side) and a tape discharge port 41H provided at the front end of the main body 41. It leads to. In the transport path 41L, the carrier tape 31 inserted into the tape insertion port 41G is transported downstream of the transport path 41L and discharged from the tape discharge port 41H. The transport path 41L extends horizontally from the tape insertion port 41G toward the downstream side, and then rises and extends in a forward diagonal direction near the center of the main body 41 in the front-rear direction. The frontmost region is exposed on the upper surface of the main body 41.

In FIG. 4, an engaging portion 41K protruding downward is provided below the main body portion 41. The main body 41 (that is, the component supply unit 14) is attached to the feeder base 22 by engaging the engaging portion 41K with a slot-shaped engaged portion (not shown) provided on the upper surface of the feeder base 22. ..

In FIG. 4, the shutter portion 42 is provided in the vicinity of the tape insertion port 41G in the main body portion 41. The shutter unit 42 includes a shutter 51 and a shutter drive unit 52. The shutter 51 abuts the lower end of the tape insertion port 41G on the transport path 41L near the tape insertion port 41G (on the carrier tape 31 when the carrier tape 31 is inserted in the transport path 41L). It is movable between the closing position at which it closes and the opening position where it is lifted upward from the closing position to open the tape insertion slot 41G. The shutter drive unit 52 operates under the control of the unit control unit 50, and lifts the shutter 51 to position it in the open position. Further, by releasing the lifting of the shutter 51 and moving the shutter 51 downward by its own weight or the force of an elastic body (not shown), the shutter 51 is positioned at the closed position.

In FIG. 4, the tape feed portion 43 is provided at the rear lower portion of the main body portion 41 and at a position downstream of the shutter portion 42. The tape feed unit 43 includes a first sprocket 61, a first drive unit 62, and an encoder 63.

The first sprocket 61 is connected to the output shaft of the first drive unit 62 via a one-way clutch (not shown). In the one-way clutch, the rotation of the output shaft in the direction of feeding the carrier tape 31 is transmitted to the first sprocket 61, but the reverse is not transmitted. Therefore, when the first drive unit 62 rotates the output shaft in the feed direction of the carrier tape 31, the first sprocket 61 also rotates in the same direction, but the first sprocket 61 becomes the first sprocket 61 while the output shaft is stopped. When a force in the feed direction of the carrier tape 31 is applied, the first sprocket 61 rotates in that direction.

The first drive unit 62 operates under the control of the unit control unit 50, and rotationally drives 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.

Below the tape feed portion 43, a tape pressing mechanism 64 that presses the carrier tape 31 in the transport path 41L against the first sprocket 61 is arranged. The tape pressing mechanism 64 is constantly urged toward the first sprocket 61 by an elastic member (not shown). The carrier tape 31 inserted from the tape insertion port 41G is inserted between the first sprocket 61 and the tape pressing mechanism 64 while pushing down the tape pressing mechanism 64.

Of the outer peripheral teeth of the first sprocket 61, the outer peripheral teeth (lowermost outer peripheral teeth) located immediately below the rotation center of the first sprocket 61 are located in the transport path 41L. Therefore, when the first sprocket 61 is rotated by the operation of the first drive unit 62, the lowermost outer peripheral teeth of the first sprocket 61 engage with the feed hole 36 of the carrier tape 31 and move downstream. , The entire carrier tape 31 proceeds downstream.

Further, the first sprocket 61 rotates when the carrier tape 31 is inserted from the tape insertion port 41G by the operator OR and the outer peripheral teeth are pushed. When the unit control unit 50 detects with the encoder 63 that the first sprocket 61 has rotated asynchronously with the operation of the tape transport unit 44 (described later), that is, that the carrier tape 31 has been inserted from the tape insertion port 41G, The first drive unit 62 is activated to pull the carrier tape 31 downstream of the transport path 41L, and transport the carrier tape 31 to a position where the tip of the carrier tape 31 reaches the replenishment tape stopper 46 or the component take-out position 14K.

The first sprocket 61 includes a plurality of outer peripheral teeth that engage the feed holes 36 of the carrier tape 31. The length of the outer peripheral teeth is less than the thickness of the carrier tape 31, and the carrier tape 31 (referred to as "leading tape 31A") leading below the first sprocket 61 and the carrier tape for replenishment (replenishing tape 31B). ) Overlap, the outer teeth engage only with the replenishment tape 31B.

In FIG. 4, the tape transport portion 44 is provided on the front upper portion of the main body portion 41. The tape transport unit 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 rotationally drives the second sprocket 71.

Of the outer peripheral teeth of the second sprocket 71, the outer peripheral teeth (uppermost outer peripheral teeth) located immediately above the rotation center of the second sprocket 71 project upward 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 of the carrier tape 31 which have been conveyed by the tape feed portion 43. Then, when the second sprocket 71 is driven by the second drive unit 72 (rotated clockwise in FIG. 4), the carrier tape 31 is conveyed downstream.

In FIG. 4, the cover member 45 is provided so as to cover the upper surface of the front end portion of the main body portion 41 from above. A gap having a height through which the carrier tape 31 can pass is formed between the cover member 45 and the upper surface of the main body 41, and the carrier tape 31 conveyed by the tape conveying portion 44 advances downstream through this gap. do.

The cover member 45 is provided with an exposed portion (not shown) for exposing the stored component BH by opening the pocket 35 for storing the component. The cover member 45 has a component take-out port (not shown) at a position above the component take-out position 14K so that the component BH positioned at the component take-out position 14K can be sucked and taken out by the nozzle 15N. It is provided. The carrier tape 31 (base tape 33) that has passed 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 (FIG. 4).

As the exposed portion, a blade for peeling the top tape 34 from the carrier tape 31 passing through the gap between the upper surface of the main body 41 and a cutter for cutting the top tape, or a roller for pulling the top tape 34 and peeling it from the carrier tape 31. Etc. can be used. The exposed portion does not necessarily have to be provided on the cover member 45, and may be provided on the main body portion 41.

The replenishment tape stopper 46 is provided at a position downstream of the outer peripheral teeth at the lowermost portion of the first sprocket 61. The operator OR can insert the replenishment tape 31B from the tape insertion port 41G even when the preceding tape 31A is in the transport path 41L. In this case, the replenishment tape 31B is inserted so as to overlap the upper surface side of the preceding tape 31A, and the first sprocket 61 can be pushed toward the back while rotating.

When the replenishment tape 31B is pushed in as described above, the tip portion thereof comes into contact with the replenishment tape stopper 46 and enters a standby state. The position for holding the replenishment tape 31B in this way is referred to as a "standby position 41T" (FIG. 4). In the present embodiment, the standby position 41T is provided in the transport path 41L, but the replenishment tape 31B may be provided outside the transport path 41L as long as it can be held downstream of the transport path 41L in a transportable state. .. Further, the tape feeding unit 43 functions as a tape feeding unit that draws the carrier tape 31 located at the standby position 41T into the transport path 41L and feeds it to the downstream side (downstream of the main body 41).

In FIG. 4, the replenishment tape detection unit 47 is provided on the slightly upstream side (rear side of the main body unit 41) of the replenishment tape stopper 46. The replenishment tape detection unit 47 has a configuration in which a roller is provided at the lower end of a probe that can move up and down, and when the carrier tape 31 traveling in the transport path 41L abuts on the roller and pushes it up, the probe also becomes a roller. It is designed to be pushed upward as a unit. Then, based on the amount of pushing up of the probe (height of the roller), the presence / absence and the number (one or two) of the carrier tapes 31 at the standby position 41T can be detected.

In FIG. 4, the operation unit 48 is provided at the rear upper part of the main body 41 (see also FIG. 5). The operation unit 48 is provided with a plurality of buttons that can be manually operated by the operator OR. The operator OR can perform various operation inputs by operating the buttons from the operation unit 48.

In FIG. 4, the display unit 49 is provided at the rear upper portion of the main body unit 41 adjacent to the operation unit 48 (see also FIG. 5). In the first embodiment, as shown in FIG. 6A, the display unit 49 has a configuration in which two 7-segment LED lighting devices 49D are arranged in the horizontal direction, and FIGS. In addition to Arabic numerals as shown in c), (d), (e), and (f), a plurality of types of characters (alphabets) are displayed as shown in FIGS. 6 (g), (h), and (i). be able to.

In FIG. 4, a unit-side connector 50C is provided at the lower part of the front end of the main body 41. The unit-side connector 50C is fitted with a connector (not shown) on the feeder carriage 21 side. Further, when the feeder carriage 21 is fitted with the connector on the base 11 side, the connector on the feeder carriage 21 side and the base 11 side are connected in a communicable state. As a result, the control unit (unit control unit 50) included in the component supply unit 14 and the control unit (mounting device control unit 19) on the component mounting device 1 side can communicate with each other.

FIG. 7 shows a control system of the component mounting device 1 including the management computer 5. In FIG. 7, the mounting device control unit 19 included in the component mounting device 1 is connected to the unit control unit 50 of each of the plurality of component supply units 14 mounted on the feeder base 22.

In FIG. 7, the unit control unit 50 of each component supply unit 14 includes a storage unit 81, a tape acceptance processing unit 82, a work start detection unit 83, a timer 84, and a remaining time display processing unit 85. The storage unit 81 stores various data necessary for the component supply unit 14 to convey the carrier tape 31. The data stored in the storage unit 81 includes the tape acceptance permission flag 81F and the work setting time 81T (FIG. 7).

The tape acceptance permission flag 81F is a flag meaning that the component supply unit 14 is in a state of being able to accept component replenishment work by the worker OR. The tape acceptance permission flag 81F is set by the management computer 5 (specifically, the work instruction unit 5A). The management computer 5 sets the tape acceptance permission flag 81F to "1" when setting the parts replenishment work to be acceptable, and sets it to "0" when it is set to the non-acceptable state. That is, for the component supply unit 14 for which the management computer 5 determines that the component BH needs to be replenished, the tape acceptance permission flag 81F is set to "1" so that the component replenishment work by the operator OR can be accepted. Further, regarding the parts supply unit 14 that does not require the parts replenishment work, even if the worker OR mistakenly requests the parts replenishment work, the parts supply unit 14 is not accepted.

The work instruction unit 5A of the management computer 5 monitors the remaining amount of the component BH of the carrier tape 31 (preceding tape 31A) for each of the plurality of component supply units 14 provided in each component mounting device 1, and the components A command for setting the tape acceptance permission flag 81F to "1" is transmitted to the unit control unit 50 to the component supply unit 14 which is determined to need to be replenished with BH.

Further, when the replenishment tape 31B is inserted into the tape insertion port 41G of the parts supply unit 14 and the parts replenishment work is completed, the work instruction unit 5A sets the tape acceptance permission flag 81F to the unit control unit 50 of the parts supply unit 14 to "0". Is sent to set.

Further, the work instruction unit 5A has a function of notifying the worker OR of the parts replenishment work for the parts supply unit 14 in which the tape acceptance permission flag 81F is set to “1”. Specifically, the position and replenishment of the parts supply unit 14 to replenish the parts BH to the touch panel 19D of the parts mounting device 1, the monitor installed in the factory (not shown), the carrying terminal carried by the worker OR, and the like. Notify the name of the part BH to be used and the storage location.

The work setting time 81T is a time set for the work performed by the worker OR on the component supply unit 14. Specifically, the time from the opening of the shutter 51 of the parts supply unit 14 to the closing, that is, the work of the worker OR inserting the replenishment tape 31B from the tape insertion port 41G of the parts supply unit 14 (parts replenishment work). ) Is the time to do it. The work setting time 81T can be set to an arbitrary value by an operation from the operation unit 48.

The tape receiving processing unit 82 controls the shutter unit 42, the replenishing tape stopper 46, and the tape feeding unit 43. The tape receiving processing unit 82 controls the opening / closing operation of the tape insertion port 41G by the shutter unit 42. Specifically, by causing the shutter driving unit 52 to perform a lifting operation and a lifting release operation of the shutter 51, the tape insertion port 41G is switched between an open state and a closed state. The shutter 51 is normally located at a closing position for closing the tape insertion port 41G, except for a time set as a time during which the carrier tape 31 can be inserted from the tape insertion port 41G. That is, the tape receiving processing unit 82 has a function of accepting or rejecting the carrier tape 31 to the component supply unit 14.

When the encoder 63 detects that the carrier tape 31 inserted from the tape insertion port 41G has rotated the first sprocket 61, the tape receiving processing unit 82 operates the first drive unit 62 to operate the first sprocket 61. To rotate. As a result, the carrier tape 31 is conveyed downstream. The tape receiving processing unit 82 determines how many carrier tapes 31 are in the standby position 41T due to the insertion of the carrier tape 31, and the preceding tape 31A in the transport path 41L at the timing when the carrier tape 31 is inserted. Control is performed to stop the first drive unit 62 according to two conditions of what kind of state it is.

When the replenishment tape detection unit 47 detects the second carrier tape 31, the tape receiving processing unit 82 determines that the replenishment tape 31B has been inserted with the preceding tape 31A present at the standby position 41T, and determines that the replenishment tape 31B has been inserted, and the tip of the replenishment tape 31B. Stops the first drive unit 62 when it reaches the replenishment tape stopper 46. As a result, the tape receiving processing unit 82 stops the replenishment tape 31B at the standby position 41T.

On the other hand, the tape receiving processing unit 82 has one carrier tape detected by the replenishment tape detecting unit 47, and the rear end of the leading tape 31A has already passed the standby position 41T, but is still present in the transport path 41L. In this case as well, it is determined that the replenishment tape 31B has been inserted, and the first drive unit 62 is stopped when the tip of the replenishment tape 31B reaches the replenishment tape stopper 46. As a result, the tape receiving processing unit 82 stops the replenishment tape 31B at the standby position 41T.

Further, in the tape receiving processing unit 82, when there is only one carrier tape 31 detected by the replenishment tape detection unit 47 and the preceding tape 31A does not exist in the transport path 41L, the replenishing tape 31B does not have the preceding tape 31A. Is determined to have been inserted, and the first drive unit 62 is stopped when the tip of the replenishment tape 31B reaches a position where the tip of the replenishment tape 31B engages with the second sprocket 71 of the tape transport unit 44. As a result, the tape receiving processing unit 82 conveys the replenishment tape 31B to the tape conveying unit 44 without stopping at the standby position 41T.

The tape receiving processing unit 82 detects that the number of carrier tapes 31 at the standby position 41T has changed from two to one while the replenishment tape 31B is waiting at the standby position 41T. That is, when it is detected that the end portion of the preceding tape 31A has passed the position of the replenishment tape detection unit 47, the replenishment tape stopper 46 is released so that the replenishment tape 31B can move downstream. Further, when the preceding tape 31A moves downstream, the tape receiving processing unit 82 drives the first driving unit 62 to convey the replenishing tape 31B downstream. As a result, the replenishment tape 31B moves in the transport path 41L so as to follow the preceding tape 31A. Then, when the replenishment tape 31B engages with the second sprocket 71 and is conveyed by the tape conveying unit 44, the first driving unit 62 is stopped.

As described above, in the first embodiment, the tape feeding section 43 has a function of pulling the carrier tape 31 located at the standby position 41T into the transport path 41L and feeding it to the downstream side (front of the main body section 41). ing. Further, the tape receiving processing unit 82 has a function of controlling the transport of the carrier tape 31 by the tape feeding unit 43.

When the management computer 5 finds a component supply unit 14 that needs to be replenished with the component BH due to the progress of the carrier tape 31 (preceding tape 31A) being conveyed and the parts running out, the management computer 5 of the component supply unit 14 The tape acceptance permission flag 81F is set to "1", and the contents of the parts replenishment work (information on the position of the parts supply unit 14 and the parts BH to be replenished) are notified to the operator OR.

The worker OR confirms the notified parts replenishment work, grasps the position of the parts supply unit 14 (hereinafter, referred to as “parts replenishment work target unit”) for which the parts BH needs to be replenished, and replenishes the parts. A reel 32 of the carrier tape 31 in which the component BH to be used is enclosed is prepared. Then, the bar code 32C (FIGS. 3A and 5) attached to the side surface of the reel 32 is scanned by the above-mentioned handy scanner HS to read the information of the prepared component BH. The information of the component BH read in this way (referred to as “read component information”) is sent to the component replenishment work support unit 5C of the management computer 5 through the handy scanner HS.

The component setup information storage unit 5B of the management computer 5 relates to the correspondence relationship between the component name of the component BH and the component supply position on the feeder base 22, and whether or not the tape of the component replenishment target unit mounted at the component supply position can be accepted. Information (supplied parts information) is stored. When the parts replenishment work support unit 5C receives the read part information from the handy scanner HS, it searches the supplied part information by the part name included in the read part information, the part name exists in the supplied part information, and the part name exists. Check whether the component replenishment target unit mounted at the component supply position corresponding to the component name is in the "tape acceptable state".

The component replenishment work support unit 5C can prepare the correct reel 32 by the worker OR when the component name exists in the supplied component information and the corresponding component replenishment target unit is in the “tape acceptable state”. A command (parts replenishment target unit notification command) for blinking the LED illumination of the display unit 49 is transmitted to the parts replenishment target unit. Upon receiving this command, the component replenishment target unit blinks the LED illumination of the display unit 49 to make the operator OR recognize the location.

Further, the parts replenishment work support unit 5C receives a signal signaling the start of the parts replenishment work from the parts replenishment target unit that has sent the command to blink the LED lighting, that is, the operator OR operates the operation unit 48 to transmit the signal. When a signal that signals the start of replenishment work is detected, a replenishment work start permission signal is transmitted. As a result, the worker OR transmits the replenishment work start permission signal only when the worker OR correctly selects the unit set as the part replenishment target unit from among the large number of part supply units 14 arranged side by side.

The work start detection unit 83 detects that the component supply unit 14 has started the component replenishment work (the work of replenishing the replenishment tape 31B to the component supply unit 14) by the worker OR. The work start detection unit 83 detects the start of the parts replenishment work by receiving the replenishment work start permission signal from the parts replenishment work support unit 5C. In the present embodiment, the work start detection unit 83 indirectly detects the start of the parts replenishment work by the replenishment work start permission signal from the parts replenishment work support unit 5C, but the operation unit of the parts replenishment target unit The start of the parts replenishment work may be detected by directly detecting that the operation of starting the parts replenishment work has been performed on the 48. Further, the work start detection unit 83 may detect the start of the component replenishment work by moving the shutter 51 to the open position by the shutter drive unit 52.

When the unit control unit 50 of the component replenishment target unit receives the replenishment work start permission signal from the component replenishment work support unit 5C, the tape receiving processing unit 82 operates the shutter drive unit 52 to move the shutter 51 to the open position. .. As a result, the component replenishment target unit is in a state where the tape insertion port 41G is open (tape acceptable state), and the operator OR can insert the replenishment tape 31B from the tape insertion port 41G.

The timer 84 measures the elapsed time from the start of the component replenishment work. The timer 84 starts measuring the time when the work start detection unit 83 detects the start of the component replenishment work. Then, when the above-mentioned work setting time 81T stored in the storage unit 81 elapses, the measurement ends. That is, the timer 84 is a measuring unit that measures the elapsed time from the start of the parts replenishment work.

The remaining time display processing unit 85 causes the display unit 49 to display (notify) the remaining time remaining for the parts replenishment work. Specifically, the remaining time display processing unit 85 calculates the remaining time by subtracting the time measured by the timer 84 from the work setting time 81T, and causes the display unit 49 to display a number corresponding to the remaining time. In the present embodiment, when the remaining time is less than 5 seconds, the countdown is displayed as "4", "3", "2", "1", "0" in 1 second increments (FIG. 6 (b) → FIG. 6 (c)-> FIG. 6 (d)-> FIG. 6 (e)-> FIG. 6 (f). In addition to the countdown display described above, the display unit 49 displays the character "On" indicating that the replenishment tape 31B has been inserted normally (FIG. 6 (h)), and displays "ER" meaning an error. "Is displayed (Fig. 6 (i)).

As described above, in the first embodiment, the display unit 49 and the remaining time display processing unit 85 have reduced the remaining time of the work setting time 81T based on the time measured by the timer 84 (a state in which the remaining time is decreasing). ) Functions as a notification unit that notifies the worker OR.

Next, the operation of the shutter 51 will be described. As shown in FIG. 8A, when 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, the operator OR is the replenishment tape 31B. Cannot be inserted from the tape insertion slot 41G and positioned at the standby position 41T (tape acceptance prohibited state). On the other hand, when the tape receiving processing unit 82 operates the shutter driving unit 52 to lift the shutter 51 from this state (arrow A1 shown in FIG. 8B), the tape insertion port 41G opens (FIG. 8B). ), The operator OR can insert the replenishment tape 31B from the tape insertion port 41G and position it at the standby position 41T (tape acceptable state).

After the shutter 51 is opened, the replenishment tape 31B is inserted from the tape insertion port 41G (FIG. 8 (b) → FIG. 8 (c)), and when the tip of the replenishment tape 31B comes into contact with the replenishment tape stopper 46 (FIG. 8). 8 (c)), the tape receiving processing unit 82 operates the shutter driving unit 52 to release the lifting of the shutter 51 to lower (drop) the shutter 51 (arrow A2 shown in FIG. 8D), and tape. The insertion slot 41G is closed (FIG. 8 (d)). As a result, further insertion of the carrier tape 31 is prohibited (prohibited state).

As described above, in the first embodiment, the shutter unit 42 (shutter 51 and shutter drive unit 52) and the tape receiving processing unit 82 put the carrier tape 31 in a prohibited state for prohibiting the carrier tape 31 from being received in the standby position 41T. It is a switching unit 90 that selectively switches between an acceptable state that allows acceptance at the standby position 41T (FIG. 7).

Next, using the flowchart of FIG. 9, the flow of the parts replenishment work performed by the worker OR for the parts supply unit 14 included in the parts mounting device 1 according to the first embodiment is targeted for the parts replenishment work. A change in the display content displayed on the display unit 49 included in the component supply unit 14 will be described.

First, the worker OR confirms the contents of the parts replenishment work notified from the work instruction unit 5A with the touch panel 19D of the parts mounting device 1, the monitor installed in the factory, the mobile terminal, etc., and stores the parts BH to be replenished. The reel 32 is prepared and the position of the component replenishment target unit on the feeder base 22 is grasped. Next, the operator OR inputs the component information by performing an operation of reading the barcode 32C of the reel 32 with the handy scanner HS (step ST1). The information of the component BH (read component information) read by the handy scanner HS is transmitted to the component replenishment work support unit 5C.

The parts replenishment work support unit 5C that has received the read part information confirms whether or not the part BH specified by the read part information is the target of the parts replenishment work notified from the work instruction unit 5A (step ST2). That is, the component replenishment work support unit 5C searches for the supply component information stored in the component setup information storage unit 5B by the component name included in the read component information, and the component name exists in the supply component information, and the component name exists in the supply component information. When the component replenishment target unit mounted at the component supply position corresponding to the component name is in the “tape acceptable state”, the component replenishment unit notification command is transmitted to the unit control unit 50 of the component replenishment target unit. When the unit control unit 50 receives the component replenishment target unit notification command, the unit control unit 50 blinks the LED illumination of the display unit 49 to notify the operator OR of the location (step ST3).

When the LED lighting of the display unit 49 of the component replenishment target unit starts blinking, the worker OR is lined up with the feeder base 22 by operating the operation unit 48 of the component supply unit 14 in which the LED lighting is blinking. From the plurality of mounted component supply units 14, one component supply unit 14 (a unit to be replenished with components if the worker OR is correct) is selected (step ST4). When the worker OR selects the parts supply unit 14 in this way, the identification information of the selected parts supply unit 14 is transmitted to the parts replenishment work support unit 5C of the management computer 5.

The parts replenishment work support unit 5C confirms whether or not the parts supply unit 14 to which the parts replenishment target unit notification command is transmitted in step ST2 and the parts supply unit 14 to which the identification information is transmitted in step ST4 match (step ST5). .. If they do not match, the parts replenishment work support unit 5C transmits an error to the parts supply unit 14 (parts supply unit 14 to which the identification information has been sent) erroneously selected by the worker OR. Then, the unit control unit 50 of the component supply unit 14 that has received the error displays the character "ER" on the display unit 49 to notify the error (FIG. 6 (i). Step ST6), and then step ST4. Return to.

On the other hand, if they match, the parts replenishment work support unit 5C transmits a replenishment work start permission signal to the unit control unit 50 of the parts replenishment target unit. Then, the tape receiving processing unit 82 of the component replenishment target unit that has received the component work start permission signal causes the shutter drive unit 52 to open the shutter 51, and the display unit 49 included in the component supply unit 14 has the character "OP". Is displayed (FIG. 6 (g). Step ST7).

At the same time, the work start detection unit 83 starts the timer 84 when it detects that the component replenishment work has been started by receiving the replenishment work start permission signal. The remaining time display processing unit 85 measures the remaining time of the work set time 81T with the timer 84, and when the remaining time becomes short, the display unit 49 displays "4" → "3" → "2" → "2" according to the remaining time. The countdown is displayed as "1" → "0" (step ST8). As a result, the worker OR is made aware of the time remaining for performing the parts replenishment work, and prompt work is promoted.

When the character "OP" is displayed on the display unit 49 of the parts replenishment target unit in step ST7, the operator OR visually confirms this (step ST9), and then a bar is inserted in the tape insertion port 41G of the parts replenishment target unit. The replenishment tape 31B pulled out from the reel 32 from which the code has been read is inserted (step ST10). When the insertion of the replenishment tape 31B by the worker OR is detected by the replenishment tape detection unit 47 of the component replenishment target unit, the unit control unit 50 of the component replenishment target unit normally replenishes the replenishment tape 31B to the display unit 49. The character "On" indicating that is displayed (FIG. 6 (h). Step ST11). The worker OR confirms that the replenishment tape 31B has been accepted by the parts supply unit 14 by displaying "On" on the display unit 49 of the parts supply unit 14 into which the replenishment tape 31B has been inserted (step ST12). .. This completes a series of parts replenishment work.

Here, the parts replenishment work support unit 5C is in the case where the part name included in the read part information is not included in the supplied part information in step ST2, or the part name is included in the supplied part information but the part name. When the component supply unit 14 corresponding to the above is not in the “tape acceptable state”, the operator OR determines that the component BH to be replenished is incorrect, and does not output the replenishment work start permission signal. Therefore, since the shutter 51 of any of the component supply units 14 does not move to the open position, the replenishment tape 31B cannot be positioned at the standby position 41T, and the operator OR mistakenly sets the replenishment tape 31B to another component supply unit. Work mistakes that replenish 14 are prevented.

FIG. 10 shows a flow of receiving processing of the replenishment tape 31B by the unit control unit 50 corresponding to the processing flow described with reference to FIG. In FIG. 10, the tape receiving processing unit 82 first waits for the work start to wait for the replenishment work start permission signal to be transmitted (step ST21). Then, when the replenishment work start permission signal is transmitted from the management computer 5 (step ST22), the tape receiving processing unit 82 operates the shutter driving unit 52 to move the shutter 51 to the open position, and the replenishment target unit receives the tape. The transition to the possible state (step ST23).

Further, the work start detection unit 83 detects that the component replenishment work has been started by receiving the replenishment work start permission signal, and starts the measurement of the work setting time 81T by the timer 84 (step ST24). Then, when the tape receiving processing unit 82 operates the shutter driving unit 52 to open the shutter 51, the display unit 49 displays the character “OP” indicating the acceptable state of the replenishment tape 31B (step ST25).

The remaining time display processing unit 85 of the component replenishment target unit measures the remaining time when the time measurement by the timer 84 is started, and when the remaining time becomes short, "4" → "3" → "2" → "1". → The display unit 49 is displayed as a countdown like “0” (step ST26). Then, when the remaining time is exhausted, the tape receiving processing unit 82 operates the shutter driving unit 52 to close the shutter 51, and shifts to the acceptance prohibition state of the replenishment tape 31B (step ST27).

When the tape acceptance processing unit 82 of the component replenishment target unit shifts to the replenishment tape acceptance prohibition state, the time measurement by the timer 84 is stopped and reset (step ST28), and the display of the display unit 49 is turned off (). FIG. 6A), a series of processes is completed (step ST29). When the shutter 51 is closed and the display of the display unit 49 is turned off in this way, if the shutter 51 is to be reopened, the operator OR needs to perform the operation of step ST1 of the flowchart shown in FIG. 9 again. There is. In step ST29, instead of turning off the display of 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.

Here, the replenishment tape 31B inserted by the operator OR from the tape insertion port 41G is detected by the replenishment tape detection unit 47 between the time when the shutter 51 is opened in step ST23 and the time when the shutter 51 is closed in step ST27. If this is done (step ST30), interrupt processing is started at that point. In the interrupt process, the unit control unit 50 closes the shutter 51 and shifts to the tape acceptance prohibition state (step ST31). As a result, it is prohibited that the carrier tape 31 is further inserted from the tape insertion port 41G after the replenishment tape 31B.

Further, in step ST31, the tape acceptance processing unit 82 sets the tape acceptance permission flag 81F to “0” and notifies the on-board device control unit 19 to that effect. As a result, the component mounting device 1 and the management computer 5 (work instruction unit 5A) are also notified that the component replenishment work has been completed.

When the tape acceptance processing unit 82 shifts to the tape acceptance prohibition state in step ST31, the time measurement by the timer 84 is stopped and reset (step ST32), and the replenishment tape 31B is normally inserted into the display unit 49. The character "On" is displayed (FIG. 6 (h). Step ST33). Then, when the predetermined time elapses (step ST34), the interrupt process is terminated and the process proceeds to step ST29 described above, the display of the display unit 49 of the component replenishment target unit is turned off, and the series of processes is completed.

As described above, in the first embodiment, the storage unit stores the work setting time 81T set for the work performed by the worker OR on the component supply unit 14 (here, the work of making the replenishment tape 31B stand by at the standby position 41T). The 81, the work start detection unit 83 that detects the state in which the work is possible (workable state), and the work start detection unit 83 that detects the state in which the work is possible are measured. A notification unit (display unit) that notifies the operator OR that the remaining time of the work setting time 81T has decreased (a state of decreasing) based on the timer 84 as the measurement unit and the time measured by the timer 84. It is configured to include 49 and a remaining time display processing unit 85). Further, the component supply unit 14 has a prohibited state in which the carrier tape 31 is prohibited from accepting the replenishment tape 31B in the standby position 41T on which the replenishment tape 31B is made to stand by, and an acceptable state in which the replenishment tape 31B is allowed to be received in the standby position 41T. A switching unit 90 that selectively switches is provided, and the time from when the switching unit 90 becomes acceptable is measured by the timer 84, and the work setting time 81T is measured based on the time measured by the timer 84. The display unit 49 as a notification unit notifies (displays) to the operator OR that the remaining time has decreased.

Therefore, the worker OR endeavors to finish the work before the remaining time runs out, and as a result, the number of times the work is redone is reduced and the productivity is improved. As described above, according to the component mounting device 1 in the first embodiment, it is possible to encourage the worker OR to perform a quick work and improve the work efficiency of the component mounting device 1.

In the above description, the storage unit 81, the timer 84, and the display unit 49 are all provided in the component supply unit 14, but a part or all of the storage unit 81, the timer 84, and the display unit 49 are the component supply unit 14. It may be provided outside the above (for example, the management computer 5). In particular, the display unit 49 (notification unit) may be provided on the feeder base 22, which is a mounting unit on which the component supply unit 14 is mounted, or a cover (base cover 12) that covers the upper part of the component supply unit 14. ) May be provided. Alternatively, the touch panel 19D provided on the base cover 12 may be used as the display unit 49.

(Embodiment 2)
Next, Embodiment 2 of the present invention will be described. The component mounting device in the second embodiment is different from the component mounting device 1 in the first embodiment in that the condition for detecting the start of the component replenishment work by the work start detection unit 83 of the component supply unit 14 and the tape of the component supply unit 14. It is a work procedure of a worker OR for shifting to an acceptable state. Therefore, in the following description, the same components as in the case of the first embodiment are designated by the same reference numerals as in the case of the first embodiment, and the description thereof will be omitted.

Using the flowchart shown in FIG. 11, the flow of the parts replenishment work performed by the worker OR for the parts supply unit 14 included in the parts mounting device 1 according to the second embodiment is divided into parts supply which is the target of the parts replenishment work. A change in the display content displayed on the display unit 49 included in the unit 14 will be described. The flowchart of FIG. 11 corresponds to the flowchart of FIG. 9 in the first embodiment, and the control contents common to the flowchart are shown with the same step numbers. Further, the replenishment tape receiving process (FIG. 10) is the same as that of the first embodiment except for step ST23.

In the second embodiment, the conditions for the work start detection unit 83 to detect the start of the component replenishment work are different from those in the first embodiment. In the first embodiment, in order for the work start detection unit 83 to detect the start of the parts replenishment work, it is necessary to go through two steps of inputting part information (step ST1) and selecting a unit to be replenished with parts (step ST4). However, in the second embodiment, the start of the parts replenishment work is detected only by inputting the parts information (step ST1). As a result, the work of the worker OR is reduced and the efficiency is improved. Therefore, the work start detection unit 83 of the second embodiment detects the start of the parts replenishment work when the unit control unit 50 receives the component replenishment target unit notification command.

As shown in FIG. 11, in the second embodiment, the component replenishment work support unit 5C has an appropriate component name included in the read component information as in the first embodiment, and the corresponding component replenishment target unit is “tape”. In the "acceptable state", a component replenishment target unit notification command is transmitted to the unit control unit 50 of the component replenishment target unit (step ST2). When the tape acceptance processing unit 82 of the unit control unit 50 of the component replenishment target unit receives the component replenishment target unit notification command, the component replenishment target unit shifts to the replenishment tape acceptable state, and “OP” is displayed on the display unit 49 (FIG. FIG. 6 (g)) is displayed (step ST7). The steps ST8 to ST12 after step ST7 shown in FIG. 11 are the same as those in the first embodiment).

Next, step ST23, which differs from the first embodiment in the replenishment tape receiving process with reference to FIG. 10, will be described. In step ST23 of the first embodiment, the tape receiving processing unit 82 operates the shutter drive unit 52 when receiving the replenishment work start permission signal from the management computer 5, but in step ST23 of the second embodiment, the parts are replenished. When the unit notification command is received, the shutter drive unit 52 is activated. Other steps are the same as in the first embodiment.

The same effect as in the case of the first embodiment can be obtained in the second embodiment, but in the second embodiment, the step including the selection of the component supply unit 14 by the worker OR in the step ST4 in the first embodiment. Since the steps of ST3 to ST6 are unnecessary, there is an advantage that the work man-hours of the worker OR are reduced as a whole.

(Embodiment 3)
Next, Embodiment 3 of the present invention will be described. The component mounting device in the third embodiment is different from the component mounting device 1 in the first embodiment only in the structure of the receiving portion of the replenishment tape 31B in the component supply unit 14 and the part related to the control of its operation. In the following description, the same components as in the case of the first embodiment are designated by the same reference numerals as in the case of the first embodiment, and the description thereof will be omitted.

FIG. 12 shows a component supply unit 14A included in the component mounting device according to the third embodiment. As shown in FIG. 12, the component supply unit 14A according to the third embodiment does not include the shutter unit 42, the replenishment tape stopper 46, and the replenishment tape detection unit 47 according to the first embodiment, and instead includes the tape insertion guide 91. It includes a tape insertion detection unit 92 and a lock mechanism 93 (see also FIG. 13).

The tape insertion guide 91 is provided above the region (referred to as “guide lower region 41R”) located at the rearmost part of the main body 41 among the transport paths 41L provided in the main body 41. The tape insertion guide 91 is composed of a pair of left and right members that support the lower surfaces of both side portions of the carrier tape 31 inserted from the tape insertion port 41G. When the operator OR inserts the carrier tape 31 into the transport path 41L, the tape insertion guide 91 supports and guides both sides of the carrier tape 31 from below.

As described above, since the tape insertion guide 91 is composed of a pair of left and right members, the carrier tape 31 inserted into the transport path 41L through the tape insertion guide 91 is subsequently (specifically, the carrier tape 31 is the first carrier tape 31). By manually pulling it down (after being conveyed by the sprocket 61) (arrow P shown in FIG. 14A), it can be moved onto the guide lower region 41R. As a result, the tape insertion guide 91 can be emptied (FIG. 14 (a) → FIG. 14 (b)), and the replenishment tape 31B can be inserted after the preceding tape 31A through the tape insertion guide 91.

In FIGS. 12 and 14 (a) and 14 (b), the tape insertion detection unit 92 is provided at a position between the outer peripheral teeth at the lowermost end of the first sprocket 61 and the tape insertion guide 91. The tape insertion detection unit 92 detects the carrier tape 31 inserted from the tape insertion port 41G through the tape insertion guide 91, and transmits information to the effect that the carrier tape 31 has been inserted from the tape insertion port 41G to the unit control unit 50A. .. The tape insertion detection unit 92 does not detect the preceding tape 31A when the preceding tape 31A is pulled down onto the guide lower region 41R (FIG. 14B).

The lock mechanism 93 prevents the first sprocket 61 from being pushed and rotated by the replenishment tape 31B inserted into the transport path 41L along the tape insertion guide 91. The tape receiving processing unit 82 of the unit control unit 50A switches the lock mechanism 93 between a state in which the rotation of the first sprocket 61 is blocked and a state in which the rotation is allowed.

When the replenishment work start permission signal is transmitted from the management computer 5, the tape receiving processing unit 82 switches the lock mechanism 93 from the state of blocking the rotation of the first sprocket 61 to the state of allowing the rotation. As a result, the component supply unit 14 is switched to the tape accepting state. Further, when the tape insertion detection unit 92 detects that the replenishment tape 31B has disappeared from the tape insertion guide 91 (standby position 41T), the unit control unit 50A blocks the lock mechanism 93 from rotating the first sprocket 61. Switch to the state. As a result, the component supply unit 14 is switched to the tape acceptance prohibition state so that even if the worker OR tries to set the carrier tape 31 by mistake, it will not be accepted.

The tape receiving processing unit 82 detects by the encoder 63 that the replenishment tape 31B is inserted into the tape insertion guide 91 of the component supply unit 14 in the tape acceptable state, and the first sprocket 61 is rotated by the replenishment tape 31B. When this is done, that is, when it is detected by the replenishment tape detection unit 47, the first drive unit 62 is operated to rotate the first sprocket 61 by a predetermined number of rotations. As a result, the replenishment tape 31B is pulled into the standby position 41T (FIG. 12).

On the other hand, in the tape acceptance prohibited state, even if the tip of the carrier tape 31 inserted from the tape insertion port 41G reaches the first sprocket 61, the lock mechanism 93 prevents the rotation of the first sprocket 61, so that the encoder 63 does not react, so the first drive unit 62 also does not activate. Therefore, the carrier tape 31 is not set at the standby position 41T. This prevents the carrier tape 31 that has been erroneously inserted from being pulled into the standby position 41T.

As described above, the component supply unit 14A in the third embodiment is a mechanism capable of mechanically preventing the insertion of the carrier tape 31 from the tape insertion port 41G as in the case of the first embodiment (in the first embodiment). Although it does not have a mechanism corresponding to the shutter portion 42), the same effect as that of the shutter portion 42 can be obtained by not rotating the first sprocket 61 with respect to the carrier tape 31 inserted from the tape insertion port 41G. It has become. In this case, the tape insertion detection unit 92, the lock mechanism 93, the tape feed unit 43, and the unit control unit 50A are prohibited from accepting the carrier tape 31 in the standby position 41T and accept the carrier tape 31 in the standby position 41T. It functions as a switching unit 90A that selectively switches between an acceptable state and an acceptable state (FIG. 13).

The replenishment tape acceptance process is the same as that of FIG. 10 except for the processes of step ST23, step ST27, and step ST31. Hereinafter, a description will be given with reference to FIG.

Step ST23 of the third embodiment is as follows. When the replenishment work permission signal is transmitted from the management computer 5 (step ST22), the tape receiving processing unit 82 switches the lock mechanism 93 from the state of blocking the rotation of the first sprocket 61 to the state of allowing the rotation. As a result, the unit to be replenished with parts is shifted to the tape acceptable state (step ST23).

Step ST27 of the embodiment is as follows. When the remaining time is exhausted, the tape receiving processing unit 82 closes the shutter 51 to shift the component replenishment target unit to the tape accepting prohibition state. However, in the present embodiment, the tape receiving processing unit 82 first locks the lock mechanism 93. Switch to a state in which the rotation of the sprocket 61 is blocked. As a result, the unit to be replenished with parts is in a tape acceptance prohibited state (step ST27).

Step ST31 of the third embodiment is as follows. If the replenishment tape 31B inserted by the operator OR from the tape insertion port 41G is detected by the replenishment tape detection unit 47 between steps ST23 and ST27 (step ST30), interrupt processing is started at that point. .. In the interrupt process, the unit control unit 50A operates the first drive unit 62 to rotate the first sprocket 61 by a predetermined amount. As a result, the replenishment tape 31B is set at the standby position 41T.

Also in the third embodiment, as in the case of the first embodiment, the remaining time display processing unit 85 is "4"-> "3"-> "2"-> "1" according to the remaining time of the work setting time 81T. → A countdown is displayed on the display unit 49 like “0”, and the time remaining for the worker OR to perform the parts replenishment work is displayed (notified) to prompt the worker OR to perform a quick work.

As described above, also in the third embodiment, the component supply unit 14 prohibits the carrier tape 31 from accepting the replenishment tape 31B in the standby position 41T, and accepts the replenishment tape 31B in the standby position 41T. It is provided with a switching unit 90A that selectively switches between an acceptable and acceptable state, measures the time from the time when the acceptable state is reached by a timer 84 as a measuring unit, and is based on the time measured by the timer 84. Therefore, the display unit 49 notifies (displays) to the worker OR that the remaining time of the work setting time 81T has decreased (a state in which the working setting time 81T has decreased). As a result, as in the case of the first embodiment, it is possible to encourage the worker OR to perform a quick work and improve the work efficiency of the component mounting device 1, and the same effect as in the case of the first embodiment can be obtained. ..

In the third embodiment, the replenishment tape detection unit 47 detects that the replenishment tape 31B has been inserted into the tape insertion port 41G, but the tape insertion detection unit 92 may detect it. .. Further, the work start detection unit 83 indirectly detects the start of the parts replenishment work by the replenishment work start permission signal from the parts replenishment work support unit 5C. The start of the parts replenishment work may be detected by directly detecting that the operation of starting the replenishment work has been performed. Further, the work start detection unit 83 may detect the start of the component replenishment work by detecting the switching from the state in which the lock mechanism 93 prevents the rotation of the first sprocket 61 to the state in which the rotation is allowed. good.

Although the embodiments of the present invention have been described so far, the present invention is not limited to the above-mentioned ones, and various modifications and the like are possible. For example, in the above-described first, second, and third embodiments, the display unit 49 is an illumination (LED illumination) that displays the remaining time of the work set time 81T, but the display unit 49 has a timer 84 that is a measurement unit. It is not limited to the above-mentioned example as long as it notifies the operator OR that the remaining time of the work setting time 81T has decreased based on the time to be measured. For example, lighting may be used to notify that the remaining time has decreased by blinking the light or changing the blinking cycle of the light.

Further, in the above-described first, second, and third embodiments, in the step (step ST1) in which the worker OR inputs the information of the component BH to the component replenishment target unit, the carrier tape 31 enclosing the component BH is wound. The barcode 32C attached to the reel 32 has been read by the handy scanner HS, but this is 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, for example, a wireless tag, or the information tag may be imaged by a camera or the like to read the information of the component BH.
