On the rear surface of the connection part 5b, a third connector 41 (see FIG. 1 ) provided with the expansion unit (automatic loading unit 40) described later is arranged. Fig. 7A ) is connected to the second connector 30.

[0051] exist Figure 4 In the embodiment, a posture stabilizing pin 27 inserted into the posture stabilizing member insertion hole 20a is arranged on the upper side of the front surface of the discharge portion 5c. A sliding member 25 that slides along the guide member 17 is arranged on the front side of the lower surface of the main body portion 5a. A position limiting pin 28 inserted into the position limiting member insertion hole 21a is arranged on the lower side of the front surface of the main body portion 5a. A connecting portion 42 (see FIG. 4 ) formed in the expansion unit (automatic loading unit 40) is formed on a part of the rear surface of the main body portion 5a and the connecting portion 5b. Fig. 7A The connected portion 5d and the second connector 30 constitute an expansion unit mounting portion 31 to which the expansion unit is mounted.

[0052] Inside the main body 5a, a conveying path 32 is provided for guiding the carrier tape T drawn out from the component reel 11 and taken into the component supply unit 5. The conveying path 32 is provided from the upstream side ( Figure 4 The insertion port 32a of the rear surface opening of the main body portion 5a is connected to the downstream side ( Figure 4The conveying path 32 is provided with a discharge port 32b which is opened on the lower surface of the discharge portion 5c on the right side of the conveying path 32. In the middle of the conveying path 32, a component taking-out position P for taking out components by the assembly head 9 is provided.

[0053] exist Figure 4 In the embodiment, a plurality of sprockets 34 are arranged inside the main body 5a, that is, below the downstream side of the conveying path 32, and are driven to rotate by a carrier conveying motor 33 arranged inside the main body 5a. In this example, three sprockets 34 for introduction, conveyance, and unloading are arranged from the upstream side. The component removal position P is set between the sprockets 34 for conveyance and unloading.

[0054] A cover tape peeling section 35 including a pair of rollers is disposed between the sprockets 34 for introduction and conveyance, i.e., above the conveyance path 32. A cover tape storage section 36 is formed inside the main body 5a, i.e., on the upstream side of the cover tape peeling section 35. In the conveyance path 32, a tape detection sensor 37 for detecting the carrier tape T inserted into the conveyance path 32 is disposed at a position further upstream than the sprockets 34 for introduction. The detection result based on the tape detection sensor 37 is sent to the feeder control section 29. In addition, the carrier tape conveyance motor 33 and the cover tape peeling section 35 are controlled by the feeder control section 29.

[0055] Next, refer to Figure 5A , Figure 5B as well as Figure 6 , the process of assembling the component supply unit 5 to the component supply unit assembly portion 6a (component supply portion C) of the carriage 6 is described. First, the height of the slide 25 of the component supply unit 5 and the guide 17 of the assembly base 6b are matched, and the component supply unit 5 is brought close to the component supply unit assembly portion 6a ( Figure 5A Further, the slide member 25 is slid along the guide member 17, and the component supply unit 5 is moved forward to the component supply unit mounting portion 6a ( Figure 5B Arrow b).

[0056] exist Figure 6 In the state where the front surface of the main body 5a of the component supply unit 5 is in contact with the rear surface of the second position limiting portion 21, the posture stabilizing pin 27 is inserted into the posture stabilizing member insertion hole 20a, the position limiting pin 28 is inserted into the position limiting portion insertion hole 21a, and the assembly portion posture stabilizing pin 16 is inserted into the pin insertion hole 24. Further, when the hook 26 engages the fixing arm 19, the assembly of the component supply unit 5 to the component supply unit assembly portion 6a is completed. At this time, the assembly portion air joint 15 is connected to the air joint 23, and the assembly portion connector 14 is connected to the first connector 22.

[0057] The component supply unit 5 defines the position in the height direction (Z direction) by abutting the slider 25 against the first position limiting portion 18 when the component supply unit is mounted on the component supply unit mounting portion 6a. In addition, the component supply unit 5 defines the position in the mounting direction (Y direction in the state where the carriage 6 is mounted on the component mounting device main body 2) of the component supply unit mounting portion 6a by abutting the second position limiting portion 21 through the main body 5a. In addition, the component supply unit 5 suppresses the axial displacement (vibration) in the mounting direction by inserting the posture stabilizing pin 27 into the posture stabilizing member insertion hole 20a and inserting the mounting portion posture stabilizing pin 16 into the pin insertion hole 24.

[0058] exist Figure 2 , Figure 6 In the embodiment, if the trolley 6 equipped with the component supply unit 5 is installed in the main body 2 of the component assembly device, the power supply unit 12 of the component assembly device 1 is connected to the component supply unit 5 via the assembly unit connector 14 and the first connector 22. Thus, power is supplied from the power supply unit 12 to the component supply unit 5. In addition, the assembly control unit 13 of the component assembly device 1 is connected to the feeder control unit 29 of the component supply unit 5 via the assembly unit connector 14 and the first connector 22. Thus, various instructions and information can be sent and received between the assembly control unit 13 and the feeder control unit 29. In addition, air can be supplied from the main body 2 of the component assembly device to the component supply unit 5 via the assembly unit air connector 15 and the air connector 23.

[0059] Next, refer to Figure 2 , Figure 6 , the conveyance of the carrier tape T in the component supply unit 5 will be described. When the front end of the carrier tape T inserted into the conveyance path 32 from the insertion port 32a is detected by the tape detection sensor 37, the feeder control unit 29 drives the carrier tape conveyance motor 33 to rotate the plurality of sprockets 34. Thus, the inserted carrier tape T is conveyed to the component removal position P by the sprockets 34 for introduction and conveyance.

[0060] While the front end of the carrier tape T is transferred from the introduction sprocket 34 to the conveying sprocket 34, the cover tape attached to the upper surface of the carrier tape T is peeled off by the cover tape peeling section 35. The peeled cover tape is collected in the cover tape storage section 36. The carrier tape T from which the components are taken out at the component taking-out position P is pushed out from the discharge port 32b to the outside by the carry-out sprocket 34. The used carrier tape T from which the components are taken out and pushed out from the discharge port 32b is collected in a used carrier tape collecting section (not shown) provided on the carriage 6.

[0061] exist Figure 2In the process, the component supply unit 5 (hereinafter referred to as the "normal feeder") in the state where the expansion unit (automatic loading unit 40) is not assembled in the expansion unit assembly section 31 performs the following component replenishment operation (overlapping): if the remaining amount of the supplied carrier tape T becomes shorter (the number of components becomes fewer), the overlapping tape is used to join the front end of the subsequent carrier tape T (hereinafter referred to as the "subsequent tape T2") at the rear end of the preceding carrier tape T (hereinafter referred to as the "preceding tape T1").

[0062] Next, refer to Fig. 7A , Figure 7B , the expansion unit used for being assembled in the component supply unit 5 is described. Here, the automatic loading unit 40 among the expansion units is described as an example. Fig. 7A In the figure, a third connector 41 connected to the second connector 30 of the component supply unit 5 is arranged on the lower side of the front surface of the automatic loading unit 40. A convex connecting portion 42 engaged with the connected portion 5d of the component supply unit 5 is formed on the upper side of the front surface of the automatic loading unit 40.

[0063] That is, the connected portion 5d is a fixing portion that fixes the assembled expansion unit to the component supply unit 5 (component supply device). In addition, the connecting portion 42 and the connected portion 5d are not limited to the concave and convex shapes as long as the expansion unit can be fixed to the component supply unit 5. Inside the automatic loading unit 40, an expansion conveying path 43 is provided to guide the carrier tape T drawn out from the component reel 11 and taken into the automatic loading unit 40. The expansion conveying path 43 is provided to communicate from the expansion insertion port 43a opened on the rear surface of the automatic loading unit 40 to the expansion discharge port 43b opened on the front surface.

[0064] exist Figure 7B In the embodiment, if the automatic loading unit 40 is mounted from the rear of the component supply unit 5 so that the connecting portion 42 is engaged with the connected portion 5d of the component supply unit 5, the second connector 30 is connected to the third connector 41. That is, the connecting portion 42 and the third connector 41 are connected to the expansion unit mounting portion 31 (connected portion 5d, second connector 30) of the component supply unit 5. In this state, the expansion conveying path 43 of the automatic loading unit 40 is connected to the conveying path 32 of the component supply unit 5, and the path of the carrier tape T is connected from the expansion insertion port 43a to the discharge port 32b.

[0065] Next, refer to Figure 8, the function of the component supply unit 5 (hereinafter referred to as "automatic loading feeder AF") in which the automatic loading unit 40 is assembled in the expansion unit assembly part 31 is described. In the automatic loading feeder AF, in the state where the components are supplied from the preceding tape T1 to the component extraction position P, the subsequent tape T2 for component replenishment can be assembled from the expansion insertion port 43a. If the preceding tape T1 is out of stock, the automatic loading feeder AF equipped with the subsequent tape T2 replaces the preceding tape T1 and automatically loads the subsequent tape T2 to the component extraction position P.

[0066] Next, refer to Fig. 9 , the structure of the tape exchange mechanism 44 provided inside the automatic loading unit 40 is described. The tape exchange mechanism 44 is configured to include: an expansion sprocket 45, a motor 46 for rotationally driving the expansion sprocket 45, a block 47, and a rod 48. The expansion sprocket 45 is provided above the expansion conveying path 43, and has a function of feeding the carrier tape T inserted into the expansion conveying path 43 in the tape feeding direction. If the automatic loading unit 40 is mounted on the component supply unit 5, the motor 46 is connected to the feeder control unit 29 via the third connector 41 and the second connector 30, and is controlled by the feeder control unit 29.

[0067] A one-way clutch 49 is disposed on the drive shaft of the expansion sprocket 45 rotated by the motor 46. The one-way clutch 49 allows the expansion sprocket 45 to rotate in the direction (arrow c) in which the expansion sprocket 45 rotates when the carrier tape T inserted from the expansion insertion port 43a moves in the tape feeding direction, but prevents the expansion sprocket 45 from rotating in the opposite direction (arrow d). Thus, the carrier tape T inserted from the expansion insertion port 43a can be prevented from falling off from the expansion insertion port 43a.

[0068] exist Fig. 9 In the embodiment, a sensor 50 for detecting the rotation of the expansion sprocket 45 is arranged in the tape exchange mechanism 44. The sensor 50 detects the rotation (arrow e) of the expansion sprocket 45 when the carrier tape T is inserted from the expansion insertion port 43a, thereby detecting the attachment of the carrier tape T. When the automatic loading unit 40 is attached to the component supply unit 5, the sensor 50 is connected to the feeder control unit 29 via the third connector 41 and the second connector 30, and the detection result based on the sensor 50 is sent to the feeder control unit 29.

[0069] Block 47 is disposed below expansion sprocket 45 across expansion conveying path 43. Block 47 has a function of pressing carrier tape T inserted into expansion conveying path 43 toward expansion sprocket 45 by urging it toward expansion sprocket 45 via an elastic body such as a spring (not shown).

[0070] exist Fig. 9In the embodiment, the rod 48 is arranged in the expansion conveying path 43 on the downstream side of the belt feeding direction relative to the expansion sprocket 45 and the block 47. The rod 48 has a stopper 48a at the end on the upstream side and a roller 48b at the end on the downstream side, and is swung using a support shaft 48c extending in a direction perpendicular to the belt feeding direction in a horizontal plane as a rotation axis. An elastic member 51 such as a spring is connected to the upper surface between the stopper 48a and the support shaft 48c of the rod 48. The rod 48 is urged in a direction of being lifted upward on the side of the stopper 48a by the elastic member 51.

[0071] exist Fig. 9 In the automatic loading unit 40, in addition to the preceding tape T1 for supplying components, the following tape T2 for replenishing components is inserted. The rod 48 resists the force of the elastic member 51 so that the roller 48b is lifted by the preceding tape T1, and the stopper 48a on the opposite side descends downward. The front end of the following tape T2 abuts against the stopper 48a at the downward descending blocking position and stops (standby).

[0072] Next, refer to FIG. 10A to FIG. 10D Next, a tape replacement process of replacing the carrier tape T of the supply component from the preceding tape T1 to the following tape T2 by the tape replacement mechanism 44 will be described. Fig. 10A Indicates from Fig. 9 The state where the components are supplied from the preceding belt T1 and the rear end of the preceding belt T1 moves to the downstream side of the block 47. Fig. 10A In the figure, the preceding belt T1 is in a state of lifting the roller 48b of the lever 48, and the following belt T2 is stopped by the stopper 48a in the blocking position.

[0073] Fig. 10B Indicates the state where the rear end of the preceding tape T1 passes through the roller 48b. If the preceding tape T1 passes, the roller 48b moves downward due to the force of the elastic member 51, and the stopper 48a moves up to the allowable position (arrow f) for allowing the subsequent tape T2 on standby to enter. Then, if the motor 46 is operated by the command from the feeder control unit 29, the expansion sprocket 45 rotates (arrow g), and the subsequent tape T2 is replenished to the component supply unit 5. That is, the subsequent tape T2 is automatically supplied to the component supply unit 5 (automatic loading) by the command from the feeder control unit 29.

[0074] exist Fig. 10C In the process, the expansion sprocket 45 rotates (arrow h) so that the subsequent belt T2 moves to the downstream side. If the subsequent belt T2 lifts the roller 48b, the stopper 48a moves to the blocking position (arrow i). Fig. 10DIn the embodiment of the present invention, if the operator inserts the next carrier tape T3 from the extended insertion port 43a (arrow j), the next carrier tape T3 enters between the extended sprocket 45 and the previous carrier tape T (subsequent tape T2), contacts the stopper 48a in the blocking position and stops. In this way, the automatic loading unit 40 as an extended unit is an automatic loading unit that automatically loads a new carrier tape T (subsequent tape T2) into the component supply unit 5.

[0075] Next, refer to Fig.11 , the structure of the control system of the component assembly device 1 is described. The assembly control unit 13 provided in the component assembly device 1 is connected to the substrate conveying unit 3, the component assembly unit 10, the reporting unit 61, the touch panel 62, and the assembly storage unit 63. In addition, the component supply unit 5 mounted in the component supply unit C (component supply unit mounting unit 6a) is connected to the assembly control unit 13 via the first connector 22 and the mounting unit connector 14. The assembly control unit 13 includes a unit control unit 64, a structure information acquisition unit 65, a stock-out judgment unit 66, and a feeder information acquisition unit 67.

[0076] The assembly control unit 13 sends and receives various information to and from an information management unit 68 such as a server that manages a production line including the component assembly device 1 via a communication network 69. The assembly storage unit 63 is a storage device that stores configuration information 63a, feeder information 63b, and the like. The reporting unit 61 is a display lamp, a buzzer, and the like, and reports warnings of shortage of the component supply unit 5, errors of improper expansion units mounted on the component supply unit 5, and the like by lighting a lamp or sounding a warning sound. The touch panel 62 displays various information on its display unit, and the operator inputs data and operates the component assembly device 1 using operation buttons and the like displayed on the display unit.

[0077] exist Fig.11 In the embodiment, the configuration information acquisition unit 65 communicates with the plurality of component supply units 5 mounted in the component supply unit C to respectively acquire configuration information of the component supply units 5. Alternatively, the configuration information acquisition unit 65 communicates with the information management unit 68 to acquire configuration information of the plurality of component supply units 5 mounted in the component supply unit C. The configuration information acquisition unit 65 stores the acquired configuration information 63a in the mounting storage unit 63.

[0078] The feeder information acquisition unit 67 communicates with the plurality of component supply units 5 mounted in the component supply unit C, and acquires feeder information including the types of the component supply units 5. Alternatively, the feeder information acquisition unit 67 communicates with the information management unit 68, and acquires feeder information of the component supply unit 5 mounted in the component supply unit C. The feeder information acquisition unit 67 stores the acquired feeder information 63b in the mounting storage unit 63.

[0079] exist Fig.11In the process, the out-of-stock judgment unit 66 counts the remaining number of components stored in the carrier tape T for supplying components based on the initial number of components stored in the carrier tape T (preceding tape T1) for supplying components from the component supply unit 5 mounted on the component supply unit C, the number of supplied components supplied by the component supply unit 5, and the like. Furthermore, the out-of-stock judgment unit 66 judges whether a stock-out has occurred in which the remaining number of components of the carrier tape T mounted on the component supply unit 5 mounted on the component supply unit C is zero, based on the remaining number of components.

[0080] The unit control unit 64 controls the component supply unit 5 mounted on the component supply unit C based on the configuration information 63a or the feeder information 63b stored in the mounting storage unit 63. Specifically, the unit control unit 64 controls the component supply unit 5 that holds the carrier tape determined to be out of stock by the out-of-stock determination unit 66 based on the configuration information 63a or the feeder information 63b, so that the component replenishment process described later is executed.

[0081] Next, refer to Fig.12 , the structure of the control system of the component supply unit 5 (component supply device) is described. The carrier tape conveying motor 33, the tape detection sensor 37, the lamp 71, the operation unit 72, the display unit 73, and the information storage unit 74 are connected to the feeder control unit 29 provided in the component supply unit 5. The feeder control unit 29 includes an action program storage unit 75 and an expansion unit identification unit 76, and controls the action of the component supply unit 5. That is, the feeder control unit 29 is a first control unit that controls the action of the component supply device (component supply unit 5).

[0082] The lamp 71 reports the operating status, shortage, etc. of the component supply unit 5 by lighting up or extinguishing. The operation unit 72 includes buttons, etc., and receives the operation of the component supply unit 5 by the operator. The display unit 73 is a liquid crystal display panel, a 7-segment LED (Light Emitting Diode), etc., and displays the operating status, etc. of the component supply unit 5 in text. The information storage unit 74 is a storage device that stores feeder information including a unique number that identifies the component supply unit 5, component information including the name of the component supplied by the component supply unit 5, the identification number of the component, the number of remaining components, etc., and the presence or absence of the subsequent belt T2 when the automatic loading unit 40 is installed.

[0083] exist Fig.12In the embodiment, in the first connector 22 of the mounting section connector 14 mounted on the component supply section C, a plurality of terminals electrically connected to the terminals of the mounting section connector 14 are provided in a predetermined configuration. The first power line 77 disposed in the component supply unit 5 is connected to the power terminal 22a of the first connector 22. When the first connector 22 is mounted on the mounting section connector 14, the first power line 77 is connected to the power supply section 12 provided in the component mounting device 1 via the power terminal 22a, and power is supplied from the power supply section 12 to the first power line 77. The first power line 77 is connected to the power circuit 78 provided in the component supply unit 5. The power circuit 78 supplies power to each part provided in the component supply unit 5.

[0084] The other end of the first communication line 82, one end of which is connected to the first communication unit 83 disposed in the component supply unit 5, is connected to the communication terminal 22b of the first connector 22. The first communication unit 83 converts a serial signal sent from the assembly control unit 13 via the first communication line 82 into a parallel signal and sends it to the feeder control unit 29. In addition, the first communication unit 83 converts a parallel signal sent from the feeder control unit 29 into a serial signal and sends it to the assembly control unit 13. The other ends of the plurality of first control lines 84, one end of which is connected to the feeder control unit 29, are respectively connected to the plurality of control terminals 22c of the first connector 22. The feeder control unit 29 and the assembly control unit 13 transmit and receive control signals via the plurality of first control lines 84.

[0085] Next, refer to Fig.12 , Fig.13 , the structure of the control system of the automatic loading unit 40 as the expansion unit and the structure of the part connected to the expansion unit in the control system of the component supply unit 5 (component supply device) are described. The third connector 41 of the automatic loading unit 40 and the plurality of terminals of the second connector 30 of the component supply unit 5, which are electrically connected to each other, are arranged in a predetermined configuration. The power terminal 30a of the second connector 30 is connected to the second power line 80 arranged in the component supply unit 5.

[0086] The second power line 80 is connected to the first power line 77 via the switch section 79 controlled by the feeder control section 29. When the feeder control section 29 turns on the switch section 79, power is supplied from the first power line 77 to the second power line 80, and when the switch section 79 is turned off, the power supply from the first power line 77 to the second power line 80 is cut off. In addition, the switch section 79 has a function of sensing the current supplied from the first power line 77 to the second power line 80, and cuts off the power supply to the second power line 80 if an overcurrent is detected. The detection terminal 30b of the second connector 30 is connected to the feeder control section 29 via the expansion unit detection line 81.

[0087] exist Fig.12 , Fig.13 In the embodiment, the other end of the third power line 90, one end of which is connected to the power circuit 91 disposed in the automatic loading unit 40, is connected to the power terminal 41a of the third connector 41 of the automatic loading unit 40. The power circuit 91 supplies power to each part of the automatic loading unit 40. The third power line 90 is connected to the detection terminal 41b of the third connector 41 via the resistor 92 having a relatively high resistance value disposed in the automatic loading unit 40. That is, by measuring the voltage of the detection terminal 41b of the third connector 41, the state of the power supplied to the third power line 90 can be detected.

[0088] Here, refer to Fig.12 , Fig.13 , a method for detecting the presence or absence of the automatic loading unit 40 (extension unit) based on the feeder control unit 29 (first control unit) is described. When the feeder control unit 29 turns on the switch unit 79 in a state where the automatic loading unit 40 is mounted on the component supply unit 5 mounted in the component supply unit C, power is supplied to the automatic loading unit 40 from the power terminal 30a of the second connector 30 of the component supply unit 5. And, the voltage of the third power line 90 is output from the detection terminal 41b of the third connector 41. In this case, the detection terminal 30b of the second connector 30 is the same voltage as the third power line 90, that is, the same (almost the same) voltage as the first power line 77.

[0089] If the feeder control unit 29 turns off the switch unit 79 when the automatic loading unit 40 is mounted on the component supply unit 5 mounted on the component supply unit C, the power supply to the automatic loading unit 40 is cut off. In this case, the detection terminal 30b of the second connector 30 is in an open circuit state. In addition, even if the feeder control unit 29 turns on the switch unit 79 when the automatic loading unit 40 is not mounted on the component supply unit 5 mounted on the component supply unit C, the detection terminal 30b of the second connector 30 remains in an open circuit state. In addition, when the expansion unit detection line 81 is pulled down, if the detection terminal 30b is in an open circuit state, the voltage of the expansion unit detection line 81 is zero.

[0090] exist Fig.12 , Fig.13 , the feeder control unit 29 measures the voltage of the detection terminal 30b of the second connector 30 via the expansion unit detection line 81. When the feeder control unit 29 turns on the switch unit 79, if the voltage of the detection terminal 30b is the same (almost the same) voltage as the first power line 77, the feeder control unit 29 determines that the automatic loading unit 40 (expansion unit) is mounted. On the other hand, when the detection terminal 30b is in an open circuit state when the feeder control unit 29 turns on the switch unit 79, the feeder control unit 29 determines that the automatic loading unit 40 is not mounted.

[0091] In this way, the second connector 30 is connected to the expansion unit detection line 81 for detecting the presence or absence of the expansion unit (automatic loading unit 40). The feeder control unit 29 detects the presence or absence of the expansion unit based on the voltage of the expansion unit detection line 81 when the switch unit 79 is turned on and off. In addition, when the switch unit 79 is turned on, if an overcurrent is detected in the power supplied to the expansion unit, the switch unit 79 cuts off the power supplied to the expansion unit. That is, the switch unit 79 is a safety circuit that monitors the power supplied to the expansion unit.

[0092] exist Fig.12 , Fig.13 In the embodiment, the other end of the second communication line 86, one end of which is connected to the second communication unit 85 disposed in the component supply unit 5, is connected to the communication terminal 30c of the second connector 30 of the component supply unit 5. The second communication unit 85 converts the parallel signal sent from the feeder control unit 29 into a serial signal and sends it to the automatic loading unit 40. In addition, the second communication unit 85 converts the serial signal sent from the automatic loading unit 40 via the second communication line 86 into a parallel signal and sends it to the feeder control unit 29.

[0093] The other end of the third communication line 93, one end of which is connected to an expansion input / output interface (expansion IO) 94 disposed in the automatic loading unit 40, is connected to the communication terminal 41c of the third connector 41 of the automatic loading unit 40. The expansion IO 94 is connected to an identification information storage unit 95 and a sensor 50 for detecting the rotation of the expansion sprocket 45. The identification information storage unit 95 is a storage device that stores information including a unique number for specifying the automatic loading unit 40, information for specifying the type of the expansion unit, and the like.

[0094] exist Fig.12 , Fig.13 In the embodiment, the expansion IO 94 converts the information stored in the identification information storage unit 95 and the detection result of the sensor 50 into a serial signal and sends it to the feeder control unit 29 via the communication terminal 41c. The expansion IO 94 converts the parallel signal sent from the feeder control unit 29 and sends it to the identification information storage unit 95 and the sensor 50. The expansion unit identification unit 76 provided in the feeder control unit 29 (first control unit) obtains the information that specifies the type of the expansion unit from the identification information storage unit 95 of the automatic loading unit 40, and identifies the type of the expansion unit connected to the second connector 30.

[0095] The action program storage unit 75 stores a plurality of action programs corresponding to the type of the expansion unit connected to the second connector 30. The expansion unit identification unit 76 obtains the action program corresponding to the identified type of the expansion unit from the action program storage unit 75 and adapts it to the control by the feeder control unit 29 (for example, updating the firmware). In this way, the feeder control unit 29 (first control unit) includes the expansion unit identification unit 76 that identifies the type of the expansion unit connected to the second connector 30 and adapts the action program to the expansion unit.

[0096] exist Fig.12 , Fig.13 In addition, the feeder control unit 29 (first control unit) notifies the component assembly device 1 of the recognition result based on the expansion unit recognition unit 76 as the structure information 63a or the feeder information 63b. That is, the feeder control unit 29 notifies the component assembly device 1 of at least any one of the information of the presence or absence of the expansion unit, the type of the expansion unit to be mounted, and the state of the operation program as the recognition result. And the structure information acquisition unit 65 acquires at least the presence or absence of the expansion unit as the structure information. In addition, the feeder information acquisition unit 67 acquires the type of the feeder (component supply unit 5) determined according to the presence or absence of the expansion unit.

[0097] The identification of the type of the expansion unit by the expansion unit identification unit 76 is performed immediately after the feeder control unit 29 turns on the switch unit 79 and starts supplying power to the expansion unit connected to the second connector 30. In the case where the expansion unit identification unit 76 cannot identify the type of the expansion unit or the expansion unit is not a regular expansion unit, the feeder control unit 29 turns off the switch unit 79 and cuts off the power supply. That is, in the case where the expansion unit identification unit 76 cannot identify the type of the expansion unit, the switch unit 79 (safety circuit) cuts off the power to the expansion unit. Thus, it is possible to prevent damage (failure) of an unclear or inappropriate expansion unit connected to the second connector 30.

[0098] exist Fig.12 , Fig.13 In the embodiment, the other ends of the plurality of second control lines 87, one end of which is connected to the feeder control unit 29, are connected to the plurality of control terminals 30d of the second connector 30. The other end of the third control line 96, one end of which is connected to the motor drive unit 97 disposed in the automatic loading unit 40, is connected to one of the plurality of control terminals 41d of the third connector 41. The motor drive unit 97 drives the motor 46 that rotationally drives the expansion sprocket 45. If the automatic loading unit 40 is mounted on the second connector 30, the feeder control unit 29 is connected to the motor drive unit 97, and the feeder control unit 29 controls the motor drive unit 97 via the second control line 87 and the third control line 96.

[0099] In this way, the component supply device (component supply unit 5) includes: a first control unit (feeder control unit 29) that controls the operation of the component supply device, a first connector 22 that electrically connects the first control unit to the second control unit (assembly control unit 13) of the component assembly device 1, and a second connector 30 that electrically connects the first control unit to the expansion unit (automatic loading unit 40) assembled in the component supply device. In addition, the second connector 30 is connected to a power line (second power line 80) for supplying power, a control line (second control line 87) for parallel communication, and a communication line (second signal line 86) for serial communication. Therefore, the component supply device can automatically expand its functions according to the assembled expansion unit.

[0100] Next, refer to Fig.14A , the structure of the wireless communication unit 100, which is an expansion unit mounted on the component supply unit 5, is described. Hereinafter, the same reference numerals are given to the same parts of the structure of the wireless communication unit 100 as those of the automatic loading unit 40, and detailed descriptions thereof are omitted. In addition to the identification information storage unit 95, the expansion IO 94 provided in the wireless communication unit 100 is also connected to a communication module 101. The communication module 101 is a communication module for wireless communication, or a wireless module for communicating with a wireless tag.

[0101] The component supply unit 5 equipped with the wireless communication unit 100 can wirelessly transmit information of the component supply unit 5 to the outside through the communication module 101. The control unit 102 is connected to the plurality of third control lines 96. The control unit 102 is connected to the status display lamp 103. If the wireless communication unit 100 is installed in the component supply unit 5, the control unit 102 is connected to the feeder control unit 29. The control unit 102 flashes the status display lamp 103 based on the command sent from the feeder control unit 29.

[0102] Next, refer to Fig. 14B , the structure of the built-in battery wireless communication unit 110 as another expansion unit mounted on the component supply unit 5 is described. Hereinafter, the same reference numerals are given to the same parts of the structure of the built-in battery wireless communication unit 110 as those of the wireless communication unit 100, and detailed descriptions thereof are omitted. The built-in battery wireless communication unit 110 includes a secondary battery 111 and a charging control unit 112 connected to the control unit 102 and controlling the charging of the secondary battery. The charging control unit 112 controls the charging and discharging of the secondary battery 111.

[0103] While the power is supplied from the component supply unit 5, in addition to supplying power from the power supply circuit 91 to each part of the built-in storage battery wireless communication unit 110, the secondary battery 111 is also charged. If the power supply from the component supply unit 5 is cut off, power is supplied from the secondary battery 111 to each part of the built-in storage battery wireless communication unit 110. Thus, even in a state where the component supply unit 5 is not connected to an external power source, by transmitting radio waves from the communication module 101 supplied with power from the secondary battery 111, information from the component supply unit 5 can be transmitted.

[0104] Next, follow Fig.15 The flow chart of FIG. 1 is to explain the expansion unit recognition process that is initially performed when the component supply unit 5 is mounted on the component supply section C (component supply unit mounting section 6a) and power is supplied from the power supply section 12 to the component supply unit 5. When power is supplied to the component supply unit 5, the feeder control section 29 turns on the switch section 79 (ST1). As a result, power can be supplied from the power terminal 30a of the second connector 30.

[0105] Next, the feeder control unit 29 measures the voltage of the detection terminal 30b of the second connector 30 to detect whether the expansion unit is mounted on the second connector 30 (ST2: expansion unit detection processing step). That is, the feeder control unit 29 determines that the expansion unit is mounted when the voltage of the detection terminal 30b is the same as the first power line 77, and determines that the expansion unit is not mounted when the detection terminal 30b is in an open state. When the expansion unit is mounted ("yes" in ST3), the expansion unit identification unit 76 of the feeder control unit 29 reads the identification information that specifies the type of the expansion unit from the identification information storage unit 95 of the expansion unit (ST4: identification information acquisition step).

[0106] exist Fig.15 In the process of step 76, when the read identification information indicates a legitimate extension unit (“Applicable” in ST5), the extension unit identification unit 76 validates the appropriate action program stored in the action program storage unit 75 (ST6: action program validation step). For example, when the action program corresponding to the extension unit indicated by the read identification information is stored in the action program storage unit 75, the extension unit identification unit 76 determines that the mounted unit is a legitimate extension unit.

[0107] Thus, the feeder control unit 29 can perform control corresponding to the installed expansion unit. That is, the component supply unit 5 is changed to a different type of feeder by installing an expansion unit for expanding the function of the component supply unit 5. For example, if the automatic loading unit 40 is installed, the component supply unit 5 becomes the automatic loading feeder AF. In addition, if the expansion unit is not installed, the component supply unit 5 is a normal feeder.

[0108] Next, the feeder control unit 29 notifies the assembly control unit 13 of the component assembly device 1 of the result of the expansion unit identification process (configuration information 63a, feeder information 63b) (ST7: result notification step). The notification result is stored in the assembly storage unit 63 of the component assembly device 1. For example, the result of the expansion unit identification process is sent as information (configuration information 63a) that can identify the structure of the component supply unit 5 by the component assembly device 1, such as the presence or absence of the expansion unit and the identification information of the installed expansion unit. Alternatively, the result of the expansion unit identification process is sent as information (feeder information 63b) that specifies the type of the component supply unit 5, such as the automatic loading feeder AF and the normal feeder.

[0109] exist Fig.15 In the case where the read identification information is not information indicating a legitimate extension unit, or the identification information is not read ("Not Suitable / Read Failed" in ST5), the feeder control unit 29 turns off the switch unit 79 to cut off the power supply to the extension unit (ST8). Next, the feeder control unit 29 causes at least one of the lamp 71 or the display unit 73 to report a warning / error (ST9). Next, a result notification step (ST7) is executed to notify the assembly control unit 13 from the feeder control unit 29 that the extension unit mounted on the component supply unit 5 is not legitimate or that the identification of the extension unit has failed.

[0110] When the expansion unit is not mounted ("No" in ST3), the feeder control unit 29 turns off the switch unit 79 to cut off the power supply to the second power terminal 30a (ST10). Next, the result notification step (ST7) is executed to notify the mounting control unit 13 that the expansion unit is not mounted in the component supply unit 5.

[0111] In this way, the information notified in the result notification step (ST7) (configuration information 63a, feeder information 63b) is acquired by the assembly control unit 13 (configuration information acquisition unit 65, feeder information acquisition unit 67) and stored in the assembly storage unit 63. That is, in the component assembly method of the component assembly apparatus 1, in which components are taken out from the component supply unit 5 mounted in the component supply unit C and mounted on the substrate B, there is included a step of acquiring the configuration information 63a of the component supply unit 5 mounted in the component supply unit C (configuration information acquisition step).

[0112] Alternatively, the component mounting method includes a step of acquiring feeder information 63b including the type of component supply unit 5 mounted on the component supply section C (feeder information acquisition step). Furthermore, the component mounting apparatus 1 controls the component supply unit 5 based on the acquired configuration information 63a or feeder information 63b (component supply unit control step), and the mounting head 9 takes out the component from the component supply unit 5 and mounts it on the substrate B (component mounting step).

[0113] Next, follow Fig.16 The out-of-stock monitoring process performed in the component assembly device 1 during the component installation operation is described below. During the component installation operation, the out-of-stock determination unit 66 of the assembly control unit 13 monitors the occurrence of out-of-stock of the component based on the remaining number of components of the component supply unit 5 assembled in the component supply unit C that supplies the components (ST11: out-of-stock monitoring process). That is, in the out-of-stock monitoring process (ST11), out-of-stock of the component of the carrier tape T is determined.

[0114] If there is no shortage (NO in ST12), the shortage monitoring process (ST11) is continued. If there is a shortage (YES in ST12), the unit control unit 64 determines the type of the component supply unit 5 that is out of stock (ST13: feeder determination process (component supply unit 5 type determination)). Specifically, the unit control unit 64 identifies whether the component supply unit 5 that holds the carrier tape T that is out of stock has an automatic loading unit 40 (automatic loading unit) based on the structure information 63a or the feeder information 63b.

[0115] exist Fig.16 In the case where the out-of-stock component supply unit 5 is the automatic loading feeder AF (YES in ST14), the unit control unit 64 confirms the mounting state of the subsequent tape T2 (ST15). When the subsequent tape T2 is set (YES in ST16), the unit control unit 64 sends a carrier tape replacement instruction to the component supply unit 5 (ST17).

[0116] That is, if the unit control unit 64 recognizes that the out-of-stock component supply unit 5 has an automatic loading unit 40 (automatic loading unit), it outputs a command to discharge the out-of-stock carrier tape T (previous tape T1) and automatically load a new carrier tape T (following tape T2) to the component supply unit 5. Then, the unit control unit 64 returns to the out-of-stock monitoring process (ST11). In addition, the assembly control unit 13 stops taking out components from the automatic loading feeder AF (or first takes out components from other component supply units 5) while the carrier tape is being replaced in the automatic loading feeder AF.

[0117] Fig.16In the process of FIG. 14 , if the subsequent tape T2 is not set (NO in ST16), the unit control section 64 sends a carrier tape discharge command to the component supply unit 5 to instruct the discharge of the preceding tape T1, and sends a component replenishment notification command to the notification section 61 or the touch panel 62 to notify the component replenishment (ST18). Then, the unit control section 64 returns to the out-of-stock monitoring process (ST11).

[0118] If the out-of-stock component supply unit 5 is a normal feeder (NO in ST14), a component replenishment reporting command is sent to the reporting unit 61 or the touch panel 62 to report the replenishment of components (ST19). That is, if the unit control unit 64 recognizes that the out-of-stock component supply unit 5 does not have the automatic loading unit 40 (automatic loading unit), it outputs a command to report the out-of-stock (component replenishment reporting command). Then, the unit control unit 64 returns to the out-of-stock monitoring process (ST11).

[0119] Thus, if the unit control unit 64 recognizes that the component supply unit 5 holding the out-of-stock carrier tape T has an automatic loading unit (automatic loading unit 40) based on the structure information 63a or the feeder information 63b (Yes in ST14), it outputs a command to discharge the out-of-stock carrier tape T (previous tape T1) and automatically load a new carrier tape T (following tape T2) to the component supply unit 5 (ST17). If it recognizes that there is no automatic loading unit (No in ST14), it outputs a command to report the out-of-stock situation (ST19). Thus, the component replenishment process of replenishing the carrier tape T can be appropriately performed according to the installed expansion unit.

[0120] Next, follow Fig.17 The flow chart of FIG. 2 is used to explain the carrier conveying process performed by the component supply unit 5, i.e., the normal feeder, which is not equipped with the expansion unit, according to the instruction from the unit control unit 64. During the component installation operation, the feeder control unit 29 waits for the instruction from the unit control unit 64 (ST21: instruction waiting process). If the instruction is not received (NO in ST22), the instruction waiting process (ST21) is continued. If the instruction is received (YES in ST22), the feeder control unit 29 controls each part of the component supply unit 5 according to the received instruction (ST23 to ST26).

[0121] Specifically, if a "1-pitch delivery instruction" is received, the feeder control unit 29 controls the carrier tape conveying motor 33 to convey the carrier tape T by 1 pitch (ST24: 1-pitch conveying process). If a "report instruction" is received, the feeder control unit 29 controls the lamp 71 and the display unit 73 to report the contents of the instruction (ST25: report processing process). In addition, the feeder control unit 29 causes it to perform various processes according to other instructions (ST26). If the received instruction is executed, the feeder control unit 29 returns to the instruction waiting process (ST21).

[0122] Next, follow Fig.18 The following is a flow chart of the carrier conveying process performed by the component supply unit 5 equipped with the automatic loading unit 40, that is, the automatic loading feeder AF, according to the instruction from the unit control unit 64. In addition, the same symbols are given to the same steps as the carrier conveying process of the normal feeder, and the detailed description is omitted. In the component installation operation, if the instruction is not received (No in ST22), the instruction waiting process (ST21) is continued. If the instruction is received (Yes in ST22), the feeder control unit 29 controls the various parts of the component supply unit 5 according to the received instruction (ST23 to ST26, ST31).

[0123] Specifically, if a "1-pitch delivery instruction" is received, a 1-pitch delivery process is executed (ST24). If a "report instruction" is received, a report processing process is executed (ST25). If a "tape exchange instruction" is received, the feeder control unit 29 controls the carrier tape conveying motor 33 and the motor driving unit 97 of the automatic loading unit 40 to execute a tape exchange process (component replenishment process) (ST31: tape exchange process process) in which the preceding tape T1 is discharged and exchanged with the following tape T2. In addition, the feeder control unit 29 executes various processes according to other instructions (ST26). If the received instruction is executed, the feeder control unit 29 returns to the instruction waiting process (ST21).

[0124] As described above, the component mounting device 1 includes: a component supply section C that detachably mounts a component supply unit 5 that supplies components stored in a carrier tape T; a structure information acquisition section 65 that acquires structure information 63a of the component supply unit 5 mounted on the component supply section C (or a feeder information acquisition section 67 that acquires feeder information 63b including the type of the component supply unit 5 mounted on the component supply section C); an assembly head 9 that mounts the components supplied from the component supply unit 5 on the substrate B; and a unit control section 64 that controls the component supply unit 5 based on the structure information 63a (or the feeder information 63b). Thus, the components can be mounted on the substrate B by a method that is automatically suitable for the structure of the component supply unit 5.

[0125] In addition, the component supply unit 5 is a component supply device that supplies components to the component mounting device 1 that mounts the components on the substrate B, and includes: a first control unit (feeder control unit 29) that controls the operation of the component supply device, a first connector 22 that electrically connects the first control unit to the second control unit (mounting control unit 13) of the component mounting device 1, and a second connector 30 that electrically connects the first control unit to the expansion unit (automatic loading unit 40) mounted on the component supply device. In addition, the second connector 30 is connected to a second power line 80 for supplying power, a second control line 87 for parallel communication, and a second communication line 86 for serial communication. Thus, the component supply device can expand its functions according to the mounted expansion unit.
