Description
[Technical field]
[0001] The present invention relates to a component mounting system for mounting components on a board, a component mounting device constituting the component mounting system, and a voltage supply method in the component mounting system. [Background technology]
[0002] Conventionally, there is known a component mounting system that mounts components on a board to produce a mounted board. The component mounting system is configured to include a component supplying device that supplies components, and a component mounting device that receives the components from the component supplying device and mounts them on the board. In such a component mounting system, a connector on the component supplying device side and a connector on the component mounting device side are connected by an operation of connecting the component supplying device to the component mounting device, and a control power supply voltage (usually 24 V DC) is supplied from the component mounting device to the component mounting device through the connected connector, thereby enabling signals to be exchanged between the component mounting device and the component mounting device (for example, see Patent Document 1 below).
[0003] In such a component mounting system, if the component supply device is of a type (e.g., a tape feeder) that is driven by a voltage at the level of the control power supply voltage, the control power supply voltage supplied from the component mounting device is used as the drive voltage for the component supply device as is. On the other hand, if the component supply device is of a type (e.g., a tray feeder) that is driven by a voltage at a level higher than the control power supply voltage (usually 200 V AC), a voltage at a level higher than the control power supply voltage must be supplied from the component mounting device to the component supply device in addition to the control power supply voltage.

[0004] [Patent Document 1] JP 2020-047801 A Summary of the Invention [Problem to be solved by the invention]
[0005] However, when a voltage having a higher voltage level than the control power supply voltage is supplied to the component supply device separately from the control power supply voltage, an operator must manually connect a dedicated connector prepared separately, and in order to ensure the safety of the work, it is necessary to temporarily turn off the power supply to the component mounting device. Therefore, when using the component supply device, the preparation work takes a lot of time, which may reduce the productivity of the component mounting system.
[0006] Here, as in the case of supplying a control power supply voltage, when a voltage level higher than the control power supply voltage is supplied, the connector on the component supply device side and the connector on the component mounting device side can be connected by connecting the component supply device to the component mounting device, and the connector on the component mounting device side can be kept live, thereby eliminating the need for workers to carry out the above-mentioned work. However, this has been difficult to adopt because there is a risk of electric shock if a worker touches a connector that is exposed in a live state.
[0007] Therefore, an object of the present invention is to provide a component mounting system, a component mounting device, and a voltage supply method for a component mounting system that can significantly shorten the preparation work time when using a component supply device that operates at a voltage level higher than the control power supply voltage, while ensuring the safety of the operator.

[0009] The component mounting device of the present invention is a component mounting device that receives components from a component supply device connected to a base and mounts the components on a board, and the component supply device is connected to a mounting device side connector that is connected to a supply device side connector of the component supply device by an operation of connecting the component supply device to the base, and The component supply device includes information about a voltage to be supplied to the component supply device, the information being stored in a storage unit of the component supply device. The component supply device includes a specification information acquisition unit that acquires specification information, and a voltage supply control unit that controls a voltage supplied to the component supply device based on the specification information acquired by the specification information acquisition unit.
[0010] The voltage supply method in a component mounting system of the present invention is a voltage supply method in a component mounting system having a component supplying device that supplies components, and a component mounting device that is connected to a base and receives components from the component supplying device and mounts the components on a board, the voltage supply method including a connector connecting step of connecting a supplying device side connector provided on the component supplying device to a mounting device side connector provided on the component mounting device by an operation of connecting the component supplying device to the base, and a voltage supplying step of connecting the supplying device side connector and the mounting device side connector connected in the connector connecting step. The component supply device includes information about a voltage to be supplied to the component supply device, the information being stored in a storage unit of the component supply device. The method includes a specification information acquisition step of acquiring specification information, a specification determination step of determining whether or not the component supplying device has specifications that require the supply of a first voltage having a voltage level higher than a control power supply voltage based on the specification information acquired in the specification information acquisition step, and a voltage supply step of supplying the first voltage to the component supplying device through the connected supplying device side connector and the mounting device side connector when it is determined in the specification determination step that the component supplying device has specifications that require the supply of the first voltage. Effect of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0013] An embodiment of the present invention will be described with reference to the drawings. Fig. 1 shows a component mounting system 1 of the present invention. The component mounting system 1 is a device that repeatedly carries in and positions a board KB supplied from the upstream side, mounts components BH on the board KB, and then carries it out to the downstream side.
[0014] 1, component mounting system 1 is configured to include a component mounting device 2 that mounts components BH on a board KB, and a component supplying device 3 that is connected to component mounting device 2 and supplies components BH to component mounting device 2. Component supplying device 3 can be freely connected to and disconnected from component mounting device 2.
[0015] As shown in Fig. 1, the component mounting device 2 includes a base 11, a transport conveyor 12, a head moving mechanism 13, a mounting head 14, and a mounting device control unit 15. In Fig. 1, the transport conveyor 12 is provided on the base 11, and transports the board KB in a horizontal direction and positions it at a predetermined work position. For convenience of explanation in the following explanation, the direction in which the transport conveyor 12 transports the board KB is defined as the X direction, and the up-down direction is defined as the Z direction. In addition, the direction perpendicular to both the X direction and the Z direction is defined as the Y direction.
[0016] 1, component supplying device 3 is made up of a tray feeder, and includes a base section 21, a pallet storage section 22, a lifting table 23, and a pallet fastener 24. When component supplying device 3 is connected to component mounting device 2 as shown in FIG. 1, it receives a voltage of a control power supply voltage level (24 V DC) from component mounting device 2 to control each section (transmit control signals to each section), and receives a voltage of a higher voltage level than the control power supply voltage (referred to as a "first voltage"; 200 V AC) to operate actuators such as lifting table 23.
[0017] As shown in Fig. 1, the base 21 of the component supplying device 3 is equipped with a plurality of casters 21a, and an operator (or an automated guided vehicle connected to the component supplying device 3) can move the component supplying device 3 on a floor surface FL. The pallet storage section 22 is a housing-like member, and holds a plurality of pallets PL aligned in the Z direction inside. Each pallet PL can be freely pulled out and stored individually in the pallet storage section 22. The pallet PL has a dish shape, and a tray TR is placed on its upper surface. A plurality of parts BH are stored in an aligned state inside the tray TR (Fig. 2(a)).
[0018] In Fig. 1, the lift table 23 is located in front of the pallet storage section 22 (on the transport conveyor 12 side). A table lift motor 25 is provided on the base section 21, and the table lift motor 25 rotates a ball screw 26 extending in the Z direction. The ball screw 26 is screwed into a nut section 23N of the lift table 23. Therefore, when the table lift motor 25 rotates the ball screw 26 about the up-down axis, the lift table 23 moves (lifts) in the Z direction (arrow A shown in Fig. 1). A pallet locking device 24 is provided on the lift table 23. The pallet locking device 24 is driven by a locking device moving mechanism 27 provided on the lift table 23 and moves in the Y direction on the lift table 23.
[0019] 1, the head moving mechanism 13 is composed of, for example, an XY table mechanism, and moves the mounting head 14 in a horizontal plane. The mounting head 14 is equipped with a plurality of nozzles 14N extending downward. The mounting head 14 can raise and lower the plurality of nozzles 14N by a built-in nozzle driving mechanism (not shown), and can also rotate the nozzles 14N around a vertical axis (Z axis). The mounting head 14 can also generate a suction force at the lower end of the nozzle 14N by supplying vacuum pressure into the nozzle 14N through a valve mechanism (not shown).
[0020] The mounting device control unit 15 controls the operation of each of the transport conveyor 12, the head moving mechanism 13, and the mounting head 14 equipped in the component mounting device 2. In addition, the mounting device control unit 15 supplies power (voltage) to the component supplying device 3 while the component supplying device 3 is connected, and exchanges signals with the component supplying device 3 to obtain necessary information from the component supplying device 3 side, thereby controlling the operation of the component supplying device 3.
[0021] When the component mounting system 1 performs a component mounting operation to mount the components BH on the board KB, the component mounting device 2 first operates the transport conveyor 12 to carry in the board KB supplied from the upstream side and position it at a prescribed work position. Once the board KB is positioned at the work position, the component supply device 3 supplies the components BH.
[0022] When the component supply device 3 supplies the components BH, first, the table lift motor 25 is operated to move the lift table 23 in the Z direction, and the lift table 23 is positioned at the height of the pallet PL to be pulled out (the pallet PL on which the tray TR storing the components BH to be picked up is placed). When the lift table 23 is positioned at the height of the pallet PL to be pulled out, the locking tool moving mechanism 27 is then operated to move the pallet locking tool 24 to the pallet PL side (FIG. 2(a)→FIG. 2(b)). When the pallet locking tool 24 is locked to the locking part HK provided at the end of the pallet PL (FIG. 2(b)), the locking tool moving mechanism 27 is operated to pull the pallet locking tool 24 forward (FIG. 2(b)→FIG. 2(c)). As a result, the pallet PL is pulled out of the pallet storage section 22 and moves onto the lift table 23 (FIG. 2(c)).
[0023] When the pallet PL to be removed is moved onto the lift table 23, the component supply device 3 operates the table lift motor 25 to raise the lift table 23 and move the lift table 23 to a height corresponding to the component supply position. As a result, the components BH in the tray TR are supplied to the component mounting device 2 (FIG. 1).
[0024] Once the components BH have been supplied by the component supply device 3, the component mounting device 2 causes the mounting head 14 to move back and forth between the component supply device 3 and the board KB, and causes the mounting head 14 to repeatedly execute a mounting turn consisting of an operation of picking up the components BH supplied by the component supply device 3 and an operation of mounting the picked-up components BH onto the board KB. Once all the components BH to be mounted on the board KB have been mounted on the board KB in this manner, the component mounting device 2 operates the transport conveyor 12 to carry the board KB out to the downstream side of the component mounting device 2.
[0025] Next, the supply of power (voltage) from the component mounting device 2 to the component supplying device 3 in the component mounting system 1 will be described. In Fig. 3 and Fig. 4(a), a rear wall 31H parallel to the XZ plane and a pair of side walls 31W consisting of YZ planes facing each other in the X direction are provided at the rear end of the base 11, and the rear wall 31H and the pair of side walls 31W form an insertion space 31 that is open to the rear. The insertion space 31 is a space for inserting the component supplying device 3 from the rear of the base 11.
[0026] 3 and 4(a) and (b), left and right couplers 32 are provided on the base 11. The left and right couplers 32 have the function of pulling the component supply device 3 inserted into the insertion space 31 from the rear of the base 11 and connecting it to the component mounting device 2.
[0027] As shown in FIG. 3, the couplers 32 are located in the insertion space 31. As also shown in FIG. 1, each coupler 32 includes an axis member 41, a hook member 42, and a drive cylinder 43. The axis member 41 extends from the side wall 31W in the X direction and is located protruding into the insertion space 31. The axis member 41 is inserted into the hook member 42, and the hook member 42 is swingable in the YZ plane around the axis member 41. The drive cylinder 43 is provided such that the piston rod 43R protrudes from the rear wall 31H into the insertion space 31. The hook member 42 is pivotally connected to the tip of the piston rod 43R. Therefore, when the drive cylinder 43 is actuated to move the piston rod 43R forward or backward, the hook member 42 swings around the axis member 41.
[0028] 3 and 4(a) and (b), a limit switch 44 is provided on one of the pair of side walls 31W. The limit switch 44 has an operating portion 44S that protrudes and extends into the insertion space 31. When the operating portion 44S is pressed backward, the limit switch 44 switches from OFF to ON and outputs a detection signal to the mounting device control portion 15.
[0029] 3 and 4(a) and (b), a first mounting device connector 51A and a second mounting device connector 51B are provided on the rear wall 31H of the base 11 as mounting device side connectors 51. The first mounting device connector 51A and the second mounting device connector 51B are arranged vertically side by side with their fitting openings facing rearward. In detail, the first mounting device connector 51A is arranged on the lower side, and the second mounting device connector 51B is arranged on the upper side. The first mounting device connector 51A is a connector for supplying a voltage (first voltage) having a voltage level higher than the control power supply voltage to the component supply device 3, and the second mounting device connector 51B is a connector for supplying a voltage (second voltage) having a voltage level of the control power supply voltage to the component supply device 3.
[0030] 5 and 6(a) and (b), a first supply device side connector 52A and a second supply device side connector 52B are provided on the front surface 3F of the component supply device 3 as the supply device side connector 52. The first supply device side connector 52A and the second supply device side connector 52B are arranged vertically side by side with their fitting openings facing forward. In detail, the first supply device side connector 52A is arranged on the lower side, and the second supply device side connector 52B is arranged on the upper side. The first supply device side connector 52A is connected (fitted) with the first mounting device side connector 51A by the operation of connecting the component supply device 3 to the base 11 of the component mounting device 2, and the second supply device side connector 52B is connected (fitted) with the second mounting device side connector 51B by the operation of connecting the component supply device 3 to the base 11 of the component mounting device 2.
[0031] 5, a pair of protrusions 53 protruding laterally (in the X direction) is provided on the left and right side surfaces of the component supplying device 3 (see also FIGS. 4(a) and (b) and FIGS. 6(a) and (b)). The pair of protrusions 53 is located at symmetrical positions on the left and right sides of the component supplying device 3.
[0032] When connecting the component supplying device 3 to the component mounting device 2, the worker (or the automated guided vehicle) runs the component supplying device 3 on the floor surface FL, and faces the front surface 3F of the component supplying device 3 against the rear wall 31H of the base 11. Then, in this state, the component supplying device 3 is moved closer to the component mounting device 2 (FIG. 4(a)→FIG. 4(b) and FIG. 6(a)→FIG. 6(b)). As the component supplying device 3 is moved closer to the component mounting device 2, the leading edge of the component supplying device 3 enters the insertion space 31 of the base 11.
[0033] When the component supplying device 3 enters the insertion space 31 of the base 11 and the front surface 3F of the component supplying device 3 reaches a predetermined position close to the rear wall 31H of the base 11, the component supplying device 3 presses the operation portion 44S of the limit switch 44 forward with its leading portion (FIG. 4(a) to FIG. 4(b)). This causes the limit switch 44 to go from off to on, and the limit switch 44 outputs a detection signal to the mounting device control portion 15. Thus, in this embodiment, the limit switch 44 serves as a supplying device detector that detects a state in which the component supplying device 3 is positioned at a predetermined position relative to the base 11 of the component mounting device 2.
[0034] When the mounting device control unit 15 receives the detection signal output by the limit switch 44, it actuates the left and right drive cylinders 43 to swing the left and right hook members 42 around the shaft members 41. As a result, the left and right hook members 42 swing so as to scoop up the left and right protrusions 53 of the component supply device 3 from below, and pull the component supply device 3 toward the rear wall 31H of the base 11 (FIG. 6(a)→FIG. 6(b)).
[0035] The component supplying device 3, which has been pulled toward the rear wall 31H of the base 11 by the left and right hook members 42, is locked by the left and right couplers 32, and the component supplying device 3 is connected to the component mounting device 2. During this connecting operation, the supplying device-side first connector 52A connects with the mounting device-side first connector 51A, and the supplying device-side second connector 52B connects with the mounting device-side second connector 51B.
[0036] As described above, in this embodiment, coupler 32 functions as a coupling means for pulling component supplying device 3 toward component mounting device 2 and coupling component supplying device 3 to component mounting device 2 when component supplying device 3 is detected by limit switch 44. Then, by the operation of coupling component supplying device 3 to base 11 of component mounting device 2 by coupler 32, which is coupling means, supplying device first connector 52A is connected to mounting device first connector 51A, and supplying device second connector 52B is connected to mounting device second connector 51B.
[0037] 7 shows a control system of the component mounting system 1 in a state where a tray feeder serving as the component supplying device 3 is connected to the component mounting device 2. As shown in this figure, the component mounting device 2 is connected to a power supply unit 61 installed externally. The power supply unit 61 is a power supply (assumed to be a 200V AC power supply) that supplies a first voltage. The power supply unit 61 is connected to a terminal block 62 provided in the component mounting device 2. The first voltage supplied by the power supply unit 61 is branched by the terminal block 62 into a plurality of voltage supply paths (supply paths of the first voltage) and supplied to each section of the component mounting device 2.
[0038] 7, some of the multiple first voltage supply paths branched at the terminal block 62 are connected to a main circuit that drives the transport conveyor 12, the head moving mechanism 13, the mounting head 14, and the drive cylinder 43. Another part of the multiple first voltage supply paths branched at the terminal block 62 is connected to an AC / DC converter 63, and the AC / DC converter 63 converts 200V AC to 24V DC to generate a control power supply voltage (second voltage). Also, another part of the multiple first voltage supply paths branched at the terminal block 62 is connected to the mounting device side first connector 51A.
[0039] 7, a first voltage supply path 81, which is a supply path of the first voltage connected to the first connector 51A of the mounting device, is provided with a normally open type electromagnetic contactor 64. The mounting device control unit 15 includes a specification information acquisition unit 65, a determination unit 66, and a safety PLC 67.
[0040] When a control signal is transmitted from the safety PLC 67, the electromagnetic contactor 64 operates to close the contact of the first voltage supply path 81. That is, the electromagnetic contactor 64 functions as a switching means for opening and closing the first voltage supply path 81, and the safety PLC 67 functions as an electromagnetic contactor control means for operating the electromagnetic contactor 64.
[0041] When the electromagnetic contactor 64 closes its contacts while the supplying device side first connector 52A is connected to the mounting device side first connector 51A, a first voltage is supplied to the component supplying device 3 through the connected mounting device side first connector 51A and supplying device side first connector 52A, making it possible to operate the table lifting motor 25 and the locking tool moving mechanism 27. That is, in this embodiment, the electromagnetic contactor 64 and the safety PLC 67 constitute a voltage supply control unit 68 that controls the voltage supplied to the component supplying device 3 (FIG. 7).
[0042] 7, the component supplying device 3 includes a control board 71. The control board 71 receives the control power supply voltage (second voltage) supplied from the component mounting device 2 in a state in which the component supplying device 3 is connected to the component mounting device 2 (the supplying device side second connector 52B and the mounting device side second connector 51B are connected), and controls the operation of the table lifting motor 25 and the locking tool moving mechanism 27, which are actuators of the component supplying device 3.
[0043] 7, a control board 71 includes a memory unit 72, which stores specification information 73 that records the specifications of the component supplying device 3. In this case, since the component supplying device 3 is a tray feeder, the specification information 73 records the specifications of the tray feeder, and also records information that a first voltage needs to be supplied.
[0044] The specification information acquisition unit 65 acquires the specification information 73 of the component supplying device 3 through the mounting device side connector 51 connected to the supplying device side connector 52 (through the mounting device side second connector 51B connected to the supplying device side second connector 52B). In detail, when the component supplying device 3 is connected to the component mounting device 2, the supplying device side second connector 52B and the mounting device side second connector 51B are connected, and the mounting device control unit 15 is able to communicate with the control board 71 by supplying a second voltage from the component mounting device 2 to the component supplying device 3, the specification information acquisition unit 65 acquires the specification information 73 by transmitting an information request to the control board 71 through the connected supplying device side second connector 52B and mounting device side second connector 51B, and the control board 71 transmits the specification information 73 of the component supplying device 3 stored in the storage unit 72 to the specification information acquisition unit 65 in response to the information request.
[0045] When the specification information acquisition unit 65 acquires the specification information of the component supplying device 3, the determination unit 66 determines whether or not the component supplying device 3 connected to the base 11 has a specification that requires the supply of a first voltage having a voltage level higher than the control power supply voltage (second voltage) based on the specification information 73 acquired by the specification information acquisition unit 65. In this case, since the component supplying device 3 is a tray feeder, the determination unit 66 determines that the component supplying device 3 has a specification that requires the supply of the first voltage.
[0046] The voltage supply control unit 68 controls the voltage to be supplied to the component supplying device 3 based on the specification information 73 acquired by the specification information acquisition unit 65. In detail, when the determination unit 66 determines that the component supplying device 3 has specifications that require the supply of the first voltage (the component supplying device 3 is a tray feeder), the voltage supply control unit 68 supplies the first voltage to the component supplying device 3 through the mounting device side connector 51 connected to the supplying device side connector 52 (the mounting device side first connector 51A connected to the supplying device side first connector 52A). The supply of the first voltage to the component supplying device 3 is performed by the safety PLC 67 sending a control signal to the electromagnetic contactor 64, which closes the contacts.
[0047] In this way, in the component mounting system 1 of this embodiment, the first voltage is supplied and the live line state is established only when the component supplying device 3 is connected to the component mounting device 2 and the supplying device side connector 52 and the mounting device side connector 51 are connected. Therefore, when the supplying device side connector 52 and the mounting device side connector 51 are not connected, the mounting device side first connector 51A is not live, and there is no risk of electric shock or the like even if an operator touches the mounting device side first connector 51A in this state. Therefore, even if the mounting device side first connector 51A is exposed before the component supplying device 3 is connected to the component mounting device 2, the safety of the operator is ensured.
[0048] 8(a) and (b) show an example in which the component supply device 3 connected to the component mounting device 2 is not a tray feeder but a carriage-equipped tape feeder. In the carriage-equipped tape feeder, the carriage DS holds the tape feeder TF and also holds a reel RL of the carrier tape CT on which the components BH are stored. The tape feeder TF conveys the carrier tape CT so as to pull it out from the reel RL by rotating the sprocket SP with a sprocket drive motor SK, thereby supplying the components BH to a predetermined component supply position. The carriage-equipped tape feeder is inserted into an insertion space 31 provided in a base 11, as in the case of a tray feeder, and is connected to the base 11 by a coupler 32 (FIG. 8(a)→FIG. 8(b)).
[0049] Unlike a tray feeder, which operates upon receiving a voltage (first voltage) at a voltage level higher than the voltage (second voltage) of the control power supply voltage level, tape feeder TF operates upon receiving a control power supply voltage (second voltage). Therefore, when component supplying device 3 is a tape feeder with a carriage, there is no need to supply the first voltage from component mounting device 2 to component supplying device 3, and a tape feeder with a carriage is not provided with a supplying device side first connector 52A as in the case of a tray feeder.
[0050] 9 shows the control system of the component mounting system 1 in a state where a carriage-equipped tape feeder is connected to the component mounting device 2 as the component supplying device 3. In this case, the specification information 73 stored in the memory unit 72 of the control board 71 of the component supplying device 3 records the specification of the tape feeder TF, and information that the supply of the first voltage is not required is recorded. Therefore, when the component supplying device 3 connected to the component mounting device 2 is a carriage-equipped tape feeder, the determination unit 66 of the component supplying device 3 determines that the component supplying device 3 does not have a specification that requires the supply of the first voltage. Then, the safety PLC 67 does not transmit a control signal to the electromagnetic contactor 64, so that the electromagnetic contactor 64 keeps the first voltage supply path 81 open (therefore, the mounting device side first connector 51A remains in a non-live state).
[0051] 10 shows a procedure of a voltage supply operation (a voltage supply method in the component mounting system 1) performed by the mounting device control unit 15 of the component mounting device 2 when the component supplying device 3 is connected to the component mounting device 2. In the voltage supply operation, the mounting device control unit 15 first monitors whether or not an input indicating that an operation of connecting the component supplying device 3 to the component mounting device 2 is to be started (connection start input) has been made (step ST1: connection start input monitoring process). Then, when the mounting device control unit 15 detects that the connection start input has been made in step ST1, it monitors whether or not the limit switch 44 is turned on (whether or not the component supplying device 3 has reached a predetermined position close to the rear wall 31H of the base 11) (step ST2: component supplying device detection process).
[0052] When the mounting device control unit 15 detects in step ST2 that the limit switch 44 has been turned on (the component supplying device 3 has reached a predetermined position), it activates the coupler 32 to couple the component supplying device 3 to the component mounting device 2, thereby connecting the supplying device side connector 52 to the mounting device side connector 51 (step ST3: connector connection process).
[0053] In step ST3, when the supplying device side connector 52 is connected to the mounting device side connector 51, the mounting device control unit 15 supplies a second voltage (control power supply voltage) to the component supplying device 3 through the connected supplying device side connector 52 and mounting device side connector 51 (specifically, the supplying device side second connector 52B and the mounting device side second connector 51B) (step ST4, second voltage supply step). Then, the component mounting device 2 acquires specification information 73 of the component supplying device 3 from the component supplying device 3 by the specification information acquisition unit 65 (step ST5, specification information acquisition step).
[0054] After acquiring the specification information 73 in step ST5, the mounting device control unit 15 judges whether the component supply device 3 is a tray feeder (whether the component supply device 3 has a specification that requires the supply of the first voltage) based on the acquired specification information 73 (step ST6, specification judgment step). As a result, if it is judged that the component supply device 3 is a tray feeder (has a specification that requires the supply of the first voltage), the mounting device control unit 15 outputs a control signal from the safety PLC 67 to the electromagnetic contactor 64 to close the contact of the electromagnetic contactor 64, and causes the component mounting device 2 to supply the first voltage to the component supply device 3 (step ST7), and ends the series of controls. This enables the component supply device 3 (tray feeder) to perform a component supply operation.
[0055] On the other hand, if the mounting device control unit 15 determines in step ST6 that the component supplying device 3 is not a tray feeder (is not designed to require the supply of the first voltage), the mounting device control unit 15 ends the series of controls without outputting a control signal from the safety PLC 67 to the electromagnetic contactor 64 and without closing the contacts of the electromagnetic contactor 64. In this case, the mounting device side first connector 51A remains in an inactive state, but there is no problem because the component supplying device 3 can drive the tape feeder TF (the sprocket drive motor SK) by the second voltage supplied from the component mounting device 2.
[0056] As described above, in the voltage supply method in the component mounting system 1 of the present embodiment, first, the component supply device 3 is connected to the component mounting device 2, thereby connecting the supply device-side connector 52 to the mounting device-side connector 51 (connector connection step). Then, the component supply device 3 acquires specification information 73 of the component supply device 3 through the connected supply device-side connector 52 and mounting device-side connector 51 (specification information acquisition step), and determines whether the component supply device 3 is of a specification that requires the supply of a first voltage having a voltage level higher than the control power supply voltage (second voltage) based on the acquired specification information 73 (specification determination step). As a result, if it is determined that the component supply device 3 is of a specification that requires the supply of the first voltage, the first voltage is supplied to the component supply device 3 through the connected supply device-side connector 52 and mounting device-side connector 51 (voltage supply step).
[0057] The flowchart in Fig. 11 shows the procedure of the voltage supply stopping operation (voltage supply stopping method) performed by the mounting device control unit 15 of the component mounting device 2 when the component supplying device 3 is separated from the component mounting device 2. In the voltage supply stopping operation, the mounting device control unit 15 first monitors whether or not an input indicating that an operation of separating the component supplying device 3 from the component mounting device 2 is to be started (separation start input) has been made (step ST11, separation start input monitoring process). Then, when the mounting device control unit 15 detects that the separation start input has been made in step ST11, it judges in the judgment unit 66 whether or not the component supplying device 3 is a tray feeder (whether or not the component supplying device 3 is of a specification that requires the supply of the first voltage) (step ST12, specification judgment process).
[0058] If the mounting device control unit 15 determines in step ST12 that the component supplying device 3 is a tray feeder (the component supplying device 3 does not have a specification that requires the supply of the first voltage), it opens the electromagnetic contactor 64 to cut off the supply of the first voltage from the component mounting device 2 to the component supplying device 3 (step ST13, voltage supply cut-off process). Then, it operates the coupler 32 to release the connected state of the component supplying device 3 (step ST14, connection release process). This makes the component supplying device 3 in a state where it can be pulled out from the insertion space 31. On the other hand, if it determines in step ST12 that the component supplying device 3 is not a tray feeder (the component mounting device 2 does not have a specification that requires the supply of the first voltage), it proceeds to step ST14 without performing the above step ST13, and operates the coupler 32 to release the connected state of the component supplying device 3.
[0059] When the component supplying device 3 becomes capable of being pulled out of the insertion space 31, the mounting device control unit 15 monitors whether the limit switch 44 changes from on to off within a predetermined time (whether the component supplying device 3 has completed separation from the component mounting device 2) (step ST15, separation completion monitoring process). If it does not detect that the limit switch 44 has turned off within the predetermined time (when the component supplying device 3 has not been pulled out of the insertion space 31), it performs a predetermined alarm operation (e.g., sounding a buzzer) (step ST16, alarm operation process) and returns to step ST15. On the other hand, if the mounting device control unit 15 detects that the limit switch 44 has turned off within the predetermined time in step ST15, it determines that the component supplying device 3 has completed separation from the component mounting device 2 and ends the series of controls.
[0060] As described above, in the component mounting system 1 in this embodiment, the component supplying device 3 is connected to the component mounting device 2, and the voltage supply control unit 68 supplies the first voltage to the component supplying device 3 only when the supplying device connector 52 and the mounting device connector 51 are connected. Therefore, when the supplying device connector 52 and the mounting device connector 51 are not connected, the mounting device first connector 51A is not in a live state, and there is no risk of electric shock or the like even if an operator touches the mounting device first connector 51A in this state. Therefore, even if the mounting device first connector 51A is exposed before the component supplying device 3 is connected to the component mounting device 2, the safety of the operator is ensured. Therefore, when the component supplying device 3 is of a specification that requires the supply of a high voltage higher than the control power supply voltage, as in the conventional case, it is not necessary for the operator to manually connect a connector dedicated to high voltage after turning off the power supply on the component mounting device 2 side, and it is possible to safely supply a high voltage to the component supplying device 3 by simply connecting the component supplying device 3 to the component mounting device 2.
[0061] Although the embodiment of the present invention has been described so far, the present invention is not limited to the above and various modifications are possible. For example, in the above embodiment, the specification information acquisition unit 65 provided in the component mounting device 2 acquires the specification information 73 through the connected supply device side connector 52 and mounting device side connector 51, but the specification information may be acquired by another method (path).
[0062] In addition, in the above-described embodiment, the first voltage is described as a voltage level (200 V AC) higher than the voltage level of the control power supply voltage, and the second voltage is described as a voltage level (24 V DC) of the control power supply voltage level, but these voltage levels are merely examples, and the voltage values are not particularly limited as long as the first voltage is higher than the second voltage.
