Figure 1 In the figure, the component assembly device 1 is configured to include: a component assembly device main body 2, which includes a base 2a; and a trolley 6, which is installed on the component assembly device main body 2. In the center of the base 2a of the component assembly device main body 2, a substrate conveying unit 3 is provided along the X direction. The substrate conveying unit 3 conveys the substrate B sent from the upstream side in the X direction, and positions and holds it at the assembly operation position assembled by the assembly head 9 described below.

A suction nozzle 9a (see FIG. 1 ) for holding the component by vacuum adsorption is mounted at the lower end of the assembly head 9. Figure 2 ).

[0061] The Y-axis table 7 and the beam 8 move the assembly head 9 in the horizontal direction (X direction, Y direction). The assembly head 9 uses a suction nozzle 9a to absorb and pick up the components supplied from the component supply unit 5 assembled on the trolley 6 installed in the trolley assembly part 4, and assembles the components to the assembly position of the substrate B positioned in the substrate conveying part 3. The Y-axis table 7, the beam 8, and the assembly head 9 move the assembly head 9 holding the components, thereby forming a component assembly part 10 that transfers and mounts the components on the substrate B.

[0062] exist Figure 2 In the embodiment, a component supply unit mounting portion 6a is provided on the upper portion of the carriage 6. The component supply unit 5 is mounted on a mounting base 6b formed on the upper surface of the component supply unit mounting portion 6a.

The fixing arms 19 engage with the hooks 26 provided on the component supply units 5 to fix the component supply units 5 mounted on the assembly base 6b. On the front side of the upper surface of the assembly base 6b, a plate-like posture stabilizing member 20 is arranged upright. On the rear side of the posture stabilizing member 20 and between the posture stabilizing member 20 and the guide 17, a second position restricting portion 21 is arranged.

[0068] A plurality of posture stabilizing member insertion holes 20a are formed on the upper portion of the rear surface of the posture stabilizing member 20 in correspondence with the plurality of component supply units 5 mounted on the mounting base 6b. A position restricting portion insertion hole 21a is formed on the rear surface of the second position restricting portion 21 in correspondence with the component supply unit 5 mounted on the mounting base 6b. The posture stabilizing pin 27 and the position restricting pin 28 formed on the component supply unit 5 are inserted into the posture stabilizing member insertion hole 20a and the position restricting portion insertion hole 21a, respectively.

[0069] Next, refer to Figure 4 The detailed structure of the component supply unit 5 (component supply device) is described below. The component supply unit 5 is composed of a main body 5a, a connecting portion 5b located at the rear side below the main body 5a, and a discharge portion 5c located at the upper side of the front of the main body 5a. A feeder control unit 29 that controls each part of the component supply unit 5 is arranged inside the connecting portion 5b.

[0070] On the front surface of the connection part 5b, a hook 26 for engaging the fixing arm 19, an air joint 23 connected to the mounting part air joint 15, a first connector 22 connected to the mounting part connector 14, and a pin insertion hole 24 for inserting the mounting part posture stabilizing pin 16 are arranged in order from the top to the bottom. On the rear surface of the connection part 5b, a second connector 30 is arranged, and the second connector 30 is connected to a third connector 41 (see FIG. 1 ) provided in the expansion unit (automatic loading unit 40) described later. Fig. 7A )connect.

[0071] 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 slider 25 that slides along the guide 17 is arranged on the front side of the lower surface of the main body 5a. A position limiting pin 28 that is inserted into the position limiting portion insertion hole 21a is arranged on the lower side of the front surface of the main body 5a. A concave connected portion 5d is formed on a part of the rear surface of the main body 5a and the connecting portion 5b, and the concave connected portion 5d is provided for the connecting portion 42 (see FIG. 4 ) formed in the expansion unit (automatic loading unit 40). Fig. 7AThe connected portion 5d and the second connector 30 constitute an expansion unit mounting portion 31 for mounting the expansion unit.

[0072] A conveying path 32 is provided inside the main body 5a, and the conveying path 32 guides the carrier tape T pulled out from the component winding rack 11 and taken into the component supply unit 5. The conveying path 32 is provided to communicate from an insertion port 32a to a discharge port 32b, and the insertion port 32a is on the upstream side (in the tape conveying direction) in the component supply unit 5. Figure 4 The rear surface of the main body 5a is open, and the discharge port 32b is on the downstream side ( Figure 4 The lower surface of the discharge portion 5c on the right side of the conveying path 32 is open. A component removal position P for the assembly head 9 to remove components is provided in the middle of the conveying path 32.

[0073] exist Figure 4 In the embodiment, a plurality of sprockets 34 are arranged inside the main body 5a and below the downstream side of the conveying path 32. The sprockets 34 are driven and rotated by the carrier conveying motor 33 arranged inside the main body 5a. In this example, three sprockets 34 are arranged from the upstream side, namely, for introduction, for conveyance, and for delivery. The component removal position P is set between the sprockets 34 for conveyance and for delivery.

[0074] A cover tape peeling section 35 including a pair of rollers is disposed between the sprockets 34 for introduction and conveyance and above the conveyance path 32. A cover tape storage section 36 is formed inside the main body 5a and 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 upstream of the sprocket 34 for introduction. The detection result detected by the tape detection sensor 37 is sent to the feeder control section 29. In addition, the carrier tape conveying motor 33 and the cover tape peeling section 35 are controlled by the feeder control section 29.

[0075] Next, refer to Figure 5A , Figure 5B and 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 below. First, the slider 25 of the component supply unit 5 is aligned with the guide 17 of the assembly base 6b, and the component supply unit 5 is brought close to the component supply unit assembly portion 6a (component supply portion C) from the rear of the carriage 6. Figure 5A Furthermore, while the slider 25 is slid along the guide 17, the component supply unit 5 is moved forward to the component supply unit mounting portion 6a ( Figure 5B Arrow b).

[0076] exist Figure 6In 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, the fixing arm 19 is engaged with the hook 26, and 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.

[0077] When the component supply unit 5 is mounted on the component supply unit mounting portion 6a, the slider 25 abuts against the first position limiting portion 18, thereby determining the position in the height direction (Z direction). In addition, the component supply unit 5 abuts against the second position limiting portion 21 through the main body 5a, thereby determining the position in the mounting direction of the component supply unit mounting portion 6a (the Y direction in the state where the carriage 6 is mounted on the main body 2 of the component mounting device). In addition, the displacement (vibration) of the component supply unit 5 around the axis in the mounting direction is suppressed 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.

[0078] exist Figure 2 , Figure 6 In the embodiment, when the trolley 6 equipped with the component supply unit 5 is installed on 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.

[0079] 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 leading 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.

[0080] 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 to the outside from the discharge port 32b by the delivery 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.

[0081] exist Figure 2 In the component supply unit 5 (hereinafter referred to as "conventional feeder") in a state where the expansion unit assembly section 31 is not assembled with the expansion unit (automatic loading unit 40), when the remaining portion of the supplied carrier tape T becomes shorter (the number of components becomes fewer), a component replenishment operation (splicing) is performed by joining the front end of the subsequent carrier tape T (hereinafter referred to as "subsequent tape T2") to the rear end of the preceding carrier tape T (hereinafter referred to as "preceding tape T1") using a splicing tape.

[0082] Next, refer to Fig. 7A , Figure 7B The expansion unit used for assembly in the component supply unit 5 is described below. Here, the automatic loading unit 40 in the expansion unit 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.

[0083] 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). It should be noted that the connecting portion 42 and the connected portion 5d are not limited to concave and convex shapes as long as they can fix the expansion unit to the component supply unit 5. An expansion conveying path 43 is provided inside the automatic loading unit 40, and the expansion conveying path 43 guides the carrier tape T pulled out from the component winding rack 11 and taken into the automatic loading unit 40. The expansion conveying path 43 is provided to connect 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 of the automatic loading unit 40.

[0084] exist Figure 7BIn the embodiment, when the automatic loading unit 40 is mounted from the rear of the component supply unit 5 in such a manner that the coupling 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 coupling 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 extended conveying path 43 of the automatic loading unit 40 is connected to the conveying path 32 of the component supply unit 5, so that the running path of the carrier tape T is connected from the extended insertion port 43a to the discharge port 32b.

[0085] 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 installed in the expansion unit installation part 31 is described. In the automatic loading feeder AF, the subsequent tape T2 for component replenishment can be installed from the expansion insertion port 43a while the components are being supplied from the preceding tape T1 to the component extraction position P. When the components of the preceding tape T1 are exhausted, the automatic loading feeder AF equipped with the subsequent tape T2 automatically loads the subsequent tape T2 toward the component extraction position P instead of the preceding tape T1.

[0086] Next, refer to Fig. 9 The structure of the tape replacement mechanism 44 provided inside the automatic loading unit 40 is described. The tape replacement mechanism 44 is configured to include an expansion sprocket 45, a motor 46 for driving the expansion sprocket 45 to rotate, 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. When the automatic loading unit 40 is assembled to 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.

[0087] A one-way clutch 49 is disposed on the drive shaft of the expansion sprocket 45 that is 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 conveying 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 out of the expansion insertion port 43a.

[0088] exist Fig. 9In the embodiment, a sensor 50 for detecting the rotation of the expansion sprocket 45 is arranged in the tape replacement mechanism 44. The sensor 50 detects the installation of the carrier tape T by detecting the rotation of the expansion sprocket 45 (arrow e) when the carrier tape T is inserted from the expansion insertion port 43a. When the automatic loading unit 40 is installed in 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 detected by the sensor 50 is sent to the feeder control unit 29.

[0089] Block 47 is disposed below expansion sprocket 45 across expansion conveyor path 43. Block 47 is urged toward expansion sprocket 45 by an elastic body such as a spring (not shown) and has a function of pressing carrier tape T inserted into expansion conveyor path 43 toward expansion sprocket 45.

[0090] exist Fig. 9 In the embodiment, the rod 48 is arranged in the expansion conveying path 43 on the downstream side of the expansion sprocket 45 and the block 47 in the belt conveying direction. 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 swings with a support shaft 48c as a rotation axis, and the support shaft 48c extends in a direction perpendicular to the belt conveying direction in a horizontal plane. An elastic member 51 such as a spring is connected to the upper surface of the rod 48 between the stopper 48a and the support shaft 48c. The stopper 48a side of the rod 48 is urged by the elastic member 51 in a direction of lifting upward.

[0091] 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 preceding tape T1 overcomes the force of the elastic member 51 and lifts the roller 48b of the lever 48, whereby the stopper 48a on the opposite side moves downward. The front end of the following tape T2 contacts the stopper 48a at the blocking position that has moved downward, and the following tape T2 stops (stands by).

[0092] Next, refer to Figure 10A to Figure 10D The 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 The supply of components from the leading belt T1 is shown. Fig. 9 The state in which the rear end of the preceding belt T1 is moved to a position downstream of the block 47 is advanced. Fig. 10A In the figure, the preceding tape T1 is in a state where the roller 48b of the lever 48 is lifted, and the following tape T2 is stopped by the stopper 48a at the blocking position.

[0093] Fig. 10BThe figure shows a state where the rear end of the preceding tape T1 passes through the roller 48b. When the preceding tape T1 passes, the roller 48b moves downward due to the force of the elastic member 51, and the stopper 48a rises to a permitted position (arrow f) for allowing the following tape T2 on standby to enter. Thereafter, when the motor 46 is operated according to the command from the feeder control unit 29, the expansion sprocket 45 rotates (arrow g) and the following tape T2 is replenished to the component supply unit 5. That is, according to the command from the feeder control unit 29, the following tape T2 is automatically supplied (automatically loaded) to the component supply unit 5.

[0094] exist Fig. 10C In the process, the expansion sprocket 45 rotates (arrow h) and the subsequent belt T2 moves to the downstream side. When the subsequent belt T2 lifts the roller 48b, the stopper 48a moves to the blocking position (arrow i). Fig. 10D When 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 preceding carrier tape T (subsequent tape T2), and abuts against the stopper 48a at 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.

[0095] 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 component exhaustion determination unit 66, and a feeder information acquisition unit 67.

The assembly storage unit 63 is a storage device that stores structure information 63a, feeder information 63b, etc. The reporting unit 61 is a display lamp, a buzzer, etc., and the component supply unit 5 reports a warning of component exhaustion, an error of an improper expansion unit mounted on the component supply unit 5, etc. by lighting a lamp, sounding a warning, etc. The touch panel 62 displays various information on its display unit, and allows the operator to input data and operate the component assembly device 1 using operation buttons, etc. displayed on the display unit.

[0097] exist Fig.11In 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 causes the mounting storage unit 63 to store the acquired configuration information 63a.

[0098] 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 causes the mounting storage unit 63 to store the acquired feeder information 63b.

[0099] exist Fig.11 In the above, the component exhaustion determination section 66 counts the remaining number of components stored in the carrier tape T to which components are supplied, based on the initial number of components stored in the carrier tape T (preceding tape T1) to which components are supplied from the component supply unit 5 mounted on the component supply section C, the number of supplied components supplied by the component supply unit 5, and the like. Furthermore, the component exhaustion determination section 66 determines whether the component exhaustion has occurred such that the remaining number of components of the carrier tape T mounted on the component supply unit 5 mounted on the component supply section C becomes zero, based on the remaining number of components.

[0100] The unit control section 64 controls the component supply unit 5 mounted on the component supply section C based on the configuration information 63a or the feeder information 63b stored in the mounting storage section 63. Specifically, the unit control section 64 controls the component supply unit 5 holding the carrier tape determined as being exhausted by the component exhaustion determination section 66 based on the configuration information 63a or the feeder information 63b, and performs the component replenishment process described later.

[0101] Next, refer to Fig.12 The structure of the control system of the component supply unit 5 (component supply device) is described below. 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 is used to control the action of the component supply unit 5. That is, the feeder control unit 29 is the first control unit that controls the action of the component supply device (component supply unit 5).

[0102] The lamp 71 reports the operating status of the component supply unit 5, the exhaustion of components, etc. by lighting up, flashing, etc. The operation unit 72 is composed of buttons, etc., and is used to accept the operator's operation of the component supply unit 5. The display unit 73 is a liquid crystal display panel, a 7-segment LED (Light Emitting Diode), etc., and is used to display the operating status of the component supply unit 5, etc. 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 remaining number of components, etc., and stores the presence or absence of the subsequent tape T2, etc. when the automatic loading unit 40 is installed.

[0103] exist Fig.12 In 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.

[0104] One end of the first communication line 82 is connected to the first communication unit 83 disposed in the component supply unit 5, and the other end of the first communication line 82 is connected to the communication terminal 22b of the first connector 22. The first communication unit 83 converts the 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 the parallel signal sent from the feeder control unit 29 into a serial signal and sends it to the assembly control unit 13. One end of the plurality of first control lines 84 is connected to the feeder control unit 29, and the other end of the plurality of first control lines 84 is 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 send and receive control signals via the plurality of first control lines 84.

[0105] Next, refer to Fig.12 , Fig.13The 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. A plurality of terminals electrically connected to each other are arranged in a predetermined arrangement in the third connector 41 of the automatic loading unit 40 and the second connector 30 of the component supply unit 5. The second power line 80 arranged in the component supply unit 5 is connected to the power terminal 30a of the second connector 30.

[0106] 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. The feeder control section 29 supplies power from the first power line 77 to the second power line 80 when the switch section 79 is turned on, and cuts off the power supply from the first power line 77 to the second power line 80 when the switch section 79 is turned off. In addition, the switch section 79 has a function of detecting 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 when 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.

[0107] exist Fig.12 , Fig.13 In the embodiment, one end of the third power line 90 is connected to a power circuit 91 disposed in the automatic loading unit 40, and the other end of the third power line 90 is connected to a power terminal 41a of a 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 a resistor 92 with a 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.

[0108] Here, refer to Fig.12 , Fig.13 Next, a method for detecting the presence or absence of the automatic loading unit 40 (extension unit) by the feeder control unit 29 (first control unit) will be 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 on 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. Then, 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 becomes the same voltage as the third power line 90, that is, the same (substantially the same) voltage as the first power line 77.

[0109] When the feeder control unit 29 turns off the switch unit 79 in a state where the automatic loading unit 40 is assembled to the component supply unit 5 assembled to 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 becomes an open circuit state. In addition, even if the feeder control unit 29 turns on the switch unit 79 in a state where the automatic loading unit 40 is not assembled to the component supply unit 5 assembled to the component supply unit C, the detection terminal 30b of the second connector 30 remains in an open circuit state. It should be noted that, in the case where the expansion unit detection line 81 is disconnected (pull down), the voltage of the expansion unit detection line 81 becomes zero when the detection terminal 30b becomes an open circuit state.

[0110] exist Fig.12 , Fig.13 In the embodiment, 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 (substantially the same) as the voltage of 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 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.

[0111] 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, the switch unit 79 cuts off the power to the expansion unit when an overcurrent is detected in 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.

[0112] exist Fig.12 , Fig.13 In the embodiment, one end of the second communication line 86 is connected to the second communication unit 85 disposed in the component supply unit 5, and the other end of the second communication line 86 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.

[0113] One end of the third communication line 93 is connected to an expansion input / output interface (expansion IO) 94 disposed in the automatic loading unit 40, and the other end of the third communication line 93 is connected to a communication terminal 41c of a third connector 41 of the automatic loading unit 40. An identification information storage unit 95 and a sensor 50 for detecting the rotation of the expansion sprocket 45 are connected to the expansion IO 94. 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.

[0114] 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 for determining 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.

[0115] The action program storage unit 75 stores a plurality of action programs corresponding to the types of the extension units connected to the second connector 30. The extension unit identification unit 76 obtains the action program corresponding to the identified type of the extension unit from the action program storage unit 75, and adapts the action program to the control (for example, firmware update) performed by the feeder control unit 29. In this way, the feeder control unit 29 (first control unit) includes the extension unit identification unit 76 that identifies the type of the extension unit connected to the second connector 30 and adapts the action program to the extension unit.

[0116] exist Fig.12 , Fig.13 In addition, the feeder control unit 29 (first control unit) notifies the component assembly device 1 of the identification result identified by the expansion unit identification 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 installed expansion unit, and the state of the operation program as the identification result. In addition, 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 by the presence or absence of the expansion unit.

[0117] 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, the expansion unit identification unit 76 identifies the type of the expansion unit. 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 to cut 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. In this way, it is possible to prevent the destruction (failure) of an unknown or inappropriate expansion unit connected to the second connector 30.

[0118] exist Fig.12 , Fig.13 In the embodiment, one end of the plurality of second control lines 87 is connected to the feeder control unit 29, and the other end of the plurality of second control lines 87 is respectively connected to the plurality of control terminals 30d of the second connector 30. One end of the third control line 96 is connected to the motor driving unit 97 disposed in the automatic loading unit 40, and the other end of the third control line 96 is connected to one of the plurality of control terminals 41d of the third connector 41. The motor driving unit 97 drives the motor 46, and the motor 46 drives the expansion sprocket 45 to rotate. When the automatic loading unit 40 is assembled to the second connector 30, the feeder control unit 29 is connected to the motor driving unit 97, and the feeder control unit 29 controls the motor driving unit 97 via the second control line 87 and the third control line 96.

[0119] 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. As a result, the component supply device can automatically expand its functions according to the assembled expansion unit.

[0120] Next, refer to Fig.14A The structure of the wireless communication unit 100 as an extension 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, a communication module 101 is connected to the extension IO 94 provided in the wireless communication unit 100. The communication module 101 is a communication module for wireless communication, or a wireless module for communicating with a wireless tag.

[0121] The component supply unit 5 equipped with the wireless communication unit 100 can send information of the component supply unit 5 to the outside in a wireless manner through the communication module 101. A control unit 102 is connected to the plurality of third control lines 96. A status display lamp 103 is connected to the control unit 102. When 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 instruction sent from the feeder control unit 29.

[0122] Next, refer to Fig. 14B The structure of the battery-mounted 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 battery-mounted wireless communication unit 110 as those of the wireless communication unit 100, and detailed descriptions thereof are omitted. The battery-mounted wireless communication unit 110 includes a secondary battery 111 and a charging control unit 112 connected to the control unit 102 and controlling charging of the secondary battery. The charging control unit 112 controls charging and discharging of the secondary battery 111.

[0123] While the power is supplied from the component supply unit 5, in addition to supplying power from the power circuit 91 to each part of the wireless communication unit with built-in battery 110, the secondary battery 111 is also charged. When 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 wireless communication unit with built-in battery 110. Thus, even when the component supply unit 5 is not connected to an external power source, the communication module 101 supplied with power from the secondary battery 111 can transmit information from the component supply unit 5 by emitting radio waves.

[0124] Next follow Fig.15 The expansion unit recognition process is described in detail below. The expansion unit recognition process is performed first 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.

[0125] 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).

[0126] exist Fig.15 In the case where the read identification information is information indicating a legitimate expansion unit (“Applicable” in ST5), the expansion 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 an action program corresponding to the expansion unit indicated by the read identification information is stored in the action program storage unit 75, the expansion unit identification unit 76 determines that the installed expansion unit is a legitimate one.

[0127] Thus, the feeder control section 29 can perform control corresponding to the attached expansion unit. That is, the component supply unit 5 is changed to a different type of feeder by attaching an expansion unit for expanding the function of the component supply unit 5. For example, when the automatic loading unit 40 is attached, the component supply unit 5 becomes the automatic loading feeder AF. In addition, when the expansion unit is not attached, the component supply unit 5 becomes a normal feeder.

[0128] 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 in the component assembly device 1, such as the presence or absence of the expansion unit and the identification information of the assembled expansion unit. Alternatively, the result of the expansion unit identification process is sent as information (feeder information 63b) that determines the type of the component supply unit 5, such as the automatic loading feeder AF and the conventional feeder.

[0129] exist Fig.15In the case where the identification information read is not information indicating a regular expansion unit, or the identification information cannot be 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 expansion unit (ST8). Next, the feeder control unit 29 causes at least one of the lamp 71 and the display unit 73 to report a warning or an error (ST9). Next, the result notification step (ST7) is executed, and the feeder control unit 29 notifies the assembly control unit 13 that the expansion unit mounted on the component supply unit 5 is not regular, or that the identification of the expansion unit has failed.

[0130] 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, a result notification step (ST7) is performed to notify the mounting control unit 13 that the expansion unit is not mounted on the component supply unit 5 from the feeder control unit 29.

[0131] 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, the component assembly method of taking out components from the component supply unit 5 mounted in the component supply unit C in the component assembly device 1 and mounting them on the substrate B includes 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).

[0132] Alternatively, the component assembly method includes a step of acquiring feeder information 63b (feeder information acquisition step), wherein the feeder information 63b includes the type of the component supply unit 5 assembled in the component supply section C. Next, the component assembly device 1 controls the component supply unit 5 based on the acquired structure information 63a or feeder information 63b (component supply unit control step), and the assembly head 9 takes out the component from the component supply unit 5 and assembles the component on the substrate B (component assembly step).

[0133] Next follow Fig.16 The component exhaustion monitoring process performed in the component assembly device 1 during the component assembly operation is described below with reference to the flowchart. During the component assembly operation, the component exhaustion determination unit 66 of the assembly control unit 13 monitors the occurrence of component exhaustion of the component based on the remaining number of components of the component supply unit 5 assembled in the component supply section C that supplies the components (ST11: component exhaustion monitoring process). That is, in the component exhaustion monitoring process (ST11), it is determined whether the components of the carrier tape T have been exhausted.

[0134] If the component has not been exhausted ("No" in ST12), the component exhaustion monitoring process (ST11) is continued. If the component has been exhausted ("Yes" in ST12), the unit control unit 64 determines the type of the component supply unit 5 in which the component has been exhausted (ST13: feeder determination process (determination of the type of the component supply unit 5)). Specifically, the unit control unit 64 identifies whether the component supply unit 5 holding the carrier tape T in which the component has been exhausted has an automatic loading unit 40 (automatic loading unit) based on the structure information 63a or the feeder information 63b.

[0135] exist Fig.16 In the case where the component supply unit 5 in which the component is exhausted 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 completely mounted ("YES" in ST16), the unit control unit 64 sends a carrier tape replacement instruction to the component supply unit 5 (ST17).

[0136] That is, if the unit control unit 64 recognizes that the component supply unit 5 that has run out of components has an automatic loading unit 40 (automatic loading unit), it outputs a command to the component supply unit 5 to discharge the carrier tape T (previous tape T1) that has run out of components and automatically load a new carrier tape T (following tape T2). After that, the unit control unit 64 returns to the component exhaustion monitoring process (ST11). It should be noted that while the carrier tape is being replaced in the automatic loading feeder AF, the assembly control unit 13 stops the removal of components from the automatic loading feeder AF (or first performs the removal of components from other component supply units 5).

[0137] exist Fig.16 If the subsequent tape T2 is not installed ("No" in ST16), the unit control unit 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 unit 61 or the touch panel 62 to notify the component replenishment (ST18). Thereafter, the unit control unit 64 returns to the component exhaustion monitoring step (ST11).

[0138] If the component supply unit 5 in which the component has run out is a normal feeder ("No" in ST14), a component replenishment report command is sent to the report unit 61 or the touch panel 62 to report the intention of component replenishment (ST19). That is, if the unit control unit 64 recognizes that the component supply unit 5 in which the component has run out does not have the automatic loading unit 40 (automatic loading unit), it outputs a command to report the component run out (component replenishment report command). Thereafter, the unit control unit 64 returns to the component run out monitoring step (ST11).

[0139] Thus, if the unit control unit 64 recognizes that the component supply unit 5 holding the carrier tape T that has run out of components has an automatic loading unit (automatic loading unit 40) based on the configuration information 63a or the feeder information 63b ("Yes" in ST14), it outputs a command to the component supply unit 5 to discharge the carrier tape T that has run out of components (previous tape T1) and automatically load a new carrier tape T (following tape T2) (ST17). If it recognizes that there is no automatic loading unit ("No" in ST14), it outputs a command to report that the component has run out (ST19). Thus, the component replenishment process of appropriately replenishing the carrier tape T can be performed according to the mounted expansion unit.

[0140] Next follow Fig.17 The following is a flow chart to explain the carrier tape conveying process performed by the component supply unit 5, i.e., the conventional feeder, which is not equipped with the expansion unit, according to the instruction from the unit control unit 64. During the component assembly operation, the feeder control unit 29 waits for the instruction from the unit control unit 64 (ST21: instruction waiting process). If no instruction is received ("No" in ST22), the instruction waiting process (ST21) is continued. When an 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).

[0141] Specifically, when receiving the "1 pitch feed instruction", the feeder control unit 29 controls the carrier tape conveying motor 33 to convey the carrier tape T by 1 pitch (ST24: 1 pitch feed process). When receiving the "report instruction", the feeder control unit 29 controls the lamp 71 and the display unit 73 to report the content of the instruction (ST25: report processing process). In addition, the feeder control unit 29 performs various processes according to other instructions (ST26). When executing the received instruction, the feeder control unit 29 returns to the instruction waiting process (ST21).

[0142] Next follow Fig.18 The following is a flow chart to illustrate the carrier conveying process performed by the component supply unit 5 equipped with the automatic loading unit 40, i.e., the automatic loading feeder AF, according to the instruction from the unit control unit 64. It should be noted that the same steps as the carrier conveying process of the conventional feeder are marked with the same figure marks and the detailed description is omitted. In the component assembly operation, if no instruction is received ("No" in ST22), the instruction waiting process (ST21) is continued. When an 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~ST26, ST31).

[0143] Specifically, when a "1 pitch feed instruction" is received, a 1 pitch feed process is executed (ST24). When a "report instruction" is received, a report processing process is executed (ST25). When a "tape replacement 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 replacement process (component replenishment process) of discharging the preceding tape T1 and replacing it with the subsequent tape T2 (ST31: tape replacement process). In addition, the feeder control unit 29 executes various processes according to other instructions (ST26). When executing the received instruction, the feeder control unit 29 returns to the instruction waiting process (ST21).

[0144] As described above, the component assembly device 1 includes: a component supply section C, to which a component supply unit 5 is assembled in a detachable manner, and the component supply unit 5 supplies components stored in a carrier tape T; a structure information acquisition section 65, which acquires structure information 63a of the component supply unit 5 assembled in the component supply section C (or a feeder information acquisition section 67, which acquires feeder information 63b including the type of the component supply unit 5 assembled in the component supply section C); an assembly head 9, which assembles the components supplied from the component supply unit 5 on the substrate B; and a unit control section 64, which controls the component supply unit 5 based on the structure information 63a (or the feeder information 63b). As a result, components can be automatically assembled on the substrate B in a suitable method corresponding to the structure of the component supply unit 5.

[0145] In addition, the component supply unit 5 is a component supply device that supplies components to the component assembly device 1 that assembles 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 (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 the second power line 80 for supplying power, the second control line 87 for parallel communication, and the second communication line 86 for serial communication. As a result, the component supply device can expand its functions according to the assembled expansion unit.
