The controller 32 is also composed mainly of a computer, and controls drive sources and the like of various devices constituting the mounting module 10. As shown in FIG. 2, the computer of the controller 32 is connected to an image processing unit 662 and an input device 664 for image processing of the image data of the CCD cameras of the

imaging devices

28 and 30, and the computer displays a display device. 666 is controlled.

Further, as shown in FIG. 2, the module main body 18 is provided with a unit storage base 672 as a unit storage member at a portion where a pair of columns 90 is provided, thereby constituting a unit storage section. . As shown in FIGS. 28 and 29, the unit storage base 672 has a shape in which a plurality of feeder main bodies 332 are arranged in parallel in the X-axis direction, and is adjacent to the feeder holding base 302 in the X-axis direction. In addition, a mounting surface or support surface 676 that is the upper surface of the unit storage base 672 is provided at a height that is located in the same plane as the upper surface of the feeder main body 332 held by the feeder holding base 302.

On the support surface 676 of the unit storage base 672, a plurality of positioning protrusions 678 are provided at two positions spaced apart in the Y-axis direction, and electromagnets are provided between the positioning protrusions 678, respectively. 680 is provided.

It is provided with an interval equal to the interval. The electromagnet 680 is provided at a position where the same positional relationship as the position of the electromagnet 620 provided on the feeder main body 332 with respect to the positioning pin 604 is obtained with respect to the positioning protrusion 678. A portion including a pair of positioning projections 678 and one electromagnet 680 separated in the Y-axis direction of the unit storage base 672 constitutes a holding part 682, and a plurality of holding parts 682 are arranged in the X-axis direction on the unit storage base 672. They are arranged at equal intervals. A guide portion 684 (see FIG. 29) similar to the guide portion 608 is provided at each upper end portion of the pair of positioning protrusions 678.

In the mounting module 10, of the two unit storage bases 672, one unit storage base 672 stores a spare component supply unit 330, and the other unit storage base 672 has an empty component supply unit 330. Stored. Storage of the spare component supply unit 330 in the unit storage base 672 is performed by an operator at an appropriate time, for example, at the time of setup change. The unit storage base 672 includes, for example, a part 366 having a high possibility of replacement, for example, a part 366 having a large number of parts mounted on the circuit board 40 among the parts supply units 330 of the bulk feeder 300 held by the feeder holding base 302. The component supply unit 330 that stores the same components 366 as the component supply unit 330 that stores the components and the component supply unit 330 that has a small number of remaining components is stored as a spare. The type of the component 366 having a large number of components 366 mounted on the circuit board 40 is taught to the operator by display on the display device 666 by a computer based on the mounting program, for example. Further, the number of remaining parts can be determined by looking at the part accommodating chamber 364 of the part supply unit 330 when the operator attaches the bulk feeder 300 to the feeder holding base 302. However, the operator may be instructed by display on the display device 666 by a computer.

When the component supply unit 330 is stored in the unit storage base 672, the worker fits the positioning protrusion 678 of the holding portion 682 in the positioning hole 606 and positions it. The operator also inputs instructions using the input device 664 so that current is supplied to the coils of the electromagnet 680 and magnetic poles are generated. At this time, energization is performed such that a magnetic pole is generated in a direction that attracts the permanent magnet 622 of the component supply unit 330 to the electromagnet 680, and the component supply unit 330 is fixed to the holding unit 682 by magnetic force. The unit storage base 672 for storing the empty unit is left empty by the operator when the component supply unit 330 is attached to the unit storage base 672.

After the component supply unit 330 is attached to the unit storage base 672, the reference mark imaging device 28 is moved to image the two-dimensional code 650 of the component supply unit 330 stored in the unit storage base 672. The height of the upper surface of the front end portion of the component supply unit 330 is positioned at the same height as the mounting surface, which is the upper surface of the circuit board 40 held by the circuit board holding device 22, and the reference mark imaging device 28 is connected to the circuit board 40. The two-dimensional code 650 can be imaged similarly to the reference mark (not shown). The imaging data is processed by the image processing unit 662 and the type of the component 366 accommodated in the component supply unit 330 is acquired. This type is sent to the computer of the controller 32 and associated with the storage position of the component supply unit 330, as spare unit storage data, spare unit storage data as a component supply unit storage data storage unit provided in the RAM of the computer. Stored in memory. In the present embodiment, the reference mark imaging device 28 and the image processing unit 662 constitute an information acquisition device. A part of the feeder holding member may be used as a unit storage portion. However, by using a portion that cannot be originally used as a feeder mounting position, such as a portion where the column 90 of the module body 18 is provided, a plurality of unit storage portions. It is not necessary to use a part of the holding unit 304 for unit storage, and the feeder 300 can be held by all the holding units 304 of the feeder holding base 302, so that it is not necessary to reduce the number of feeders for supplying parts.

The supply of the component 366 by the bulk feeder 300 will be described.
In the bulk feeder 300 attached to the feeder holding base 302, the component supply unit 330 is positioned with respect to the feeder main body 332 by fitting the positioning pins 604 into the positioning holes 606. In addition, the energization of the coil generates a magnetic pole in a direction that attracts the permanent magnet 622 to the electromagnet 620, and the component supply unit 330 is fixed to the feeder body 332 by a magnetic force. Further, the shutter 484 is always in the operating position, covers the component outlet 474, and prevents the component 366 abutted against the end surface 480 from jumping out from the component outlet 474.

When the component 366 is mounted on the circuit board 40, the mounting head 50 is positioned at the lower end position with respect to the X-axis slide 88 and is moved by the mounting head moving device 52. The mounting head 50 is positioned above the component outlet 474 of the bulk feeder 300 where the suction nozzle 100 receives the component 366, and is lowered with respect to the holder holding body 112 by the holder lifting device 114 to suck the component 366. .

Prior to taking out the component 366 by the suction nozzle 100, the shutter 484 is opened. The drive motor 450 is rotated in the direction opposite to the direction in which the magnet disk 388 is rotated (the direction indicated by the broken arrow in FIG. 14), and the drive plate 564 is rotated in the clockwise direction in FIG. Accordingly, the protrusion 568 engages with the rear side surface of the notch 570, and the shutter 484 is retracted from the operating position to the open position against the urging force of the spring 494.

The gear 460 is rotated by the rotation of the drive motor 450, but the magnet disk 388 is not rotated by the action of the first and second one-way clutches and remains stationary. Further, the rod 550 is advanced, air is discharged from the discharge port of the plunger pump 540, and pressurized air is injected from the nozzle 420. As a result, even if the part 366 gets on the portion between the adjacent magnet parts 416 of the cylindrical surface 410 and is moved toward the chute 470 by the rotation of the magnet disk 388, it is attracted by the magnet part 416. The parts 366 that are not present are blown off by the pressurized air and separated from the magnet disk 388, and a state in which the magnet disk 388 holds the parts 366 only in the magnet portion 416 is obtained.

The suction nozzle 100 that sucks the component 366 is raised, and the component 366 is taken out from the component outlet 474. The mounting head 50 is moved to the circuit board holding device 22 after all the suction nozzles 100 hold the parts 366 and mounts the parts 366 on the circuit board 40. After the circuit board 40 is carried onto the circuit board holding device 22 by the

board conveyor

34 or 36, the pin support plate 202 is lifted by the support plate lifting / lowering device 240 and supported from below by the support pins 200. In addition, the reference mark provided on the circuit board 40 is imaged by the reference mark imaging device 28, the position error of the component mounting location set on the circuit board 40 is acquired, and the component 366 is accurately mounted on the component mounting location. To be made.

In the bulk feeder 300, after the parts are taken out, the drive motor 450 is started and the magnet disk 388 is rotated in the direction of rotation (the direction indicated by the solid line arrow in FIG. 14). As a result, the magnet disk 388 is rotated in the direction indicated by the arrow A in FIG. 14, and the component 366 attracted by the magnet unit 416 is moved and sent to the chute 470. In this embodiment, the drive motor 450 is rotated by an angle at which a plurality of, for example, two parts 366 are put into the chute 470 by the rotation of the magnet disk 388. While moving in the component layer 402, the magnet unit 416 attracts the component 366 and sends it to the chute 470.

The component 366 has a normal posture, that is, a posture in which the longitudinal direction thereof is along the circumferential direction of the cylindrical surface 410, and is a normal position, that is, a position adsorbed to the cylindrical surface 410 and the shoulder surface 412 without protruding from the cylindrical surface 410. If it is, the regulating member 430 is passed through as it is, but if the posture or position of the component 366 is not a normal posture or position, it is separated from the magnet portion 416 by the regulating member 430. For example, as shown in FIG. 30A, the component 366 has a posture in which the longitudinal direction intersects the longitudinal direction of the annular notch 414 and is parallel to the rotation axis of the magnet disk 388. If it is adsorbed by the portion 416 and protrudes from the cylindrical surface 410, the component 366 rides on the inclined surface 432 when it reaches the regulating member 430. The component 366 is separated from the cylindrical surface 410 as the magnet disk 388 rotates due to the inclination of the inclined surface 432, and is separated from the magnet part 416 and detached from the magnet disk 388.

Alternatively, as shown in FIG. 30B, the component 366 is adsorbed in a posture in which the longitudinal direction is substantially parallel to the longitudinal direction of the annular notch 414, but on the opposite side from the cylindrical surface 410 to the shoulder surface 412. Even when it protrudes, it rides on the inclined surface 432, disengages from the magnet portion 416, and is detached from the magnet disk 388. As a result, the component 366 is moved in a posture in which it cannot enter the passage 528, and it is avoided that the component 366 collides with the cover 512 and is damaged.

After the component 366 passes through the regulating member 430, it reaches the upper end of the magnet disk 388, and after passing the upper end position, the component 366 is moved in a direction to reenter the component layer 402, but a cover 512 is provided. Since the component 366 moves in a state covered with the cover 512 until reaching the start end of the chute 470, the component layer 402 is prevented from coming into contact with the component 366 attracted to the magnet portion 416. The component 366 attracted by the magnet unit 416 is not displaced from the magnet unit 416.

When the part 366 reaches the start end of the chute 470, it moves along the scooping surface 522 of the scraper 520, is scooped from the magnet part 416, and is guided into the chute 470. The component 366 is guided by a guide surface 526 provided adjacent to the rake surface 522, and is surely placed on the rake surface 522, guided to the chute 470, and reaches the component supply unit 382. The component 366 in the component storage chamber 384 is poorly attracted by the magnet portion 416 of the magnet disk 388, blown off by the pressurized air of the component 366 not attracted to the magnet portion 416, and poor in posture and position by the regulating member 430. The parts 366 are aligned in one row by being detached, and in this state, are fed into the passage 528 at the upper end of the magnet disk 388 and positioned by the parts supply unit 382. The magnet disk 388 is a component of the component moving device 384 in the function of attracting the component 366 in the component accommodating chamber 364, moving the component 366 by its rotation, and applying a moving force to the component 366, and the magnet unit 416. The component 366 is adsorbed and aligned in a line along the cylindrical surface 410, and is also a component of the alignment / positioning device 386, together with the regulating member 430, the cover 512, the nozzle 420, the chute 470, the end surface 480, etc. An alignment / positioning device 386 is configured.

When the drive motor 450 is rotated in the direction of rotating the magnet disk 388, the link 576 is retracted, and the drive plate 564 is rotated in the direction indicated by the solid arrow in FIG. At this time, the shutter 484 is moved forward by following the protrusion 568 of the drive plate 564 by the bias of the spring 494, moved to the operating position, and closes the component outlet 474. The forward movement of the shutter 484 is stopped by contacting the stopper 496, but the drive motor 450 is further rotated from this state, and the drive plate 564 is further rotated. This rotation is allowed when the protrusion 568 moves away from the rear side surface of the notch 570 and moves in the notch 570.

Also, the rod 550 is retracted, negative pressure is supplied into the

passages

544 and 546 by the plunger pump 540, the air in the chute 470 is sucked, and the component 366 is moved to the component outlet 474. When the drive motor 450 is further rotated from the state where the shutter 484 has reached the operating position, the rod 550 is also retracted. Therefore, it is ensured that the air in the

passages

544 and 546 is sucked and the component 366 is moved in a state where the component outlet 474 is closed. Even if the component 366 enters between the magnet disc 388 and the bottom surface 404 of the component storage chamber 364, the magnet disc 388 is slid and rotated with respect to the component 366.

In the mounting module 10, the support pins 200 of the circuit board holding device 22 are automatically arranged on the pin support plate 202. Further, in the mounting module 10 to which electronic circuit components are supplied by the bulk feeder 300, the component supply unit 330 attached to the feeder main body 332 is stored in the unit storage base 672, and the components supplied in the unit storage base 672 are supplied. The unit 330 is automatically attached to the feeder main body 332. All of these are performed by the automatic pin attachment / detachment device 248. In this embodiment, the unit automatic attachment / detachment device and the pin automatic attachment / detachment device are combined, the support pin gripping head 250 constitutes the unit holding head, and the mounting head moving device 52 and the unit holding head moving device are combined, The Z-axis slide 124 constitutes a unit holding head holding unit and a mounting head holding unit, and the mounting head 50 and the unit holding head are held together by the dual head holding unit and moved together.

When the support pins 200 are arranged, the pin support plate 202 is positioned at the rising end position. However, the gripping pins 630 of the component supply unit 330 attached to the feeder main body 332 and the component supply unit stored in the unit storage base 672. Since the pin 630 to be gripped 630 is positioned at a position higher than the support pin 200 positioned at the rising end position and the support pin 200 stored in the support pin storage device 244, the support pin gripping head 250 is automatically connected to the support pin 200. At the time of arrangement, the X-axis slide 88 is positioned at the descending end position, and when the component supply unit 330 is replaced, it is positioned at the ascending end position, and the support pin gripping device 252 is moved by the support pin gripping device lifting device 254 at each position. The head body 110 is moved up and down. In a state where the support pin gripping head 250 is positioned at the rising end position, the mounting head 50 is also positioned at the rising end position and does not interfere with the component housing portion 362 of the component supply unit 330.

The placement of the support pins 200 on the pin support plate 202 is performed at the time of setup change. At this time, the position of the support pin 200 actually mounted on the pin support plate 202 is changed, or the excess support pin 200 is removed from the pin support plate 202 and stored in the support pin storage device 244, or is insufficient. The support pin 200 is taken out from the support pin storage device 244 and attached to the pin support plate 202.

For example, when the support pin 200 supported by the pin support plate 202 is stored in the support pin storage device 244, the support pin gripping head 250 is moved onto the stored support pin 200 by the mounting head moving device 52. Then, the support pin gripping device 252 is lowered by the support pin gripping device lifting / lowering device 254. With this lowering, when the gripping

claws

268 and 270 are closed to grip the support pin 200 and the support pin gripping device 252 is raised, the support pin 200 is lifted from the pin support plate 202 against the magnetic force. In this state, the support pin gripping head 250 is moved onto the empty pin storage hole 248 of the support pin storage device 244 by the mounting head moving device 52. Support pin storage data indicating in which of the plurality of pin storage holes 248 of the support pin storage device 244 the support pin 200 is stored or empty is created in advance, and the support pin provided in the computer RAM of the controller 32 It is stored in the stored data memory. After the support pin gripping head 250 is moved, the support pin gripping device 252 is lowered and the support pin 200 is fitted into the pin receiving hole 248. When the support pin gripping device 252 is raised, the support pin 200 is ungripped by the gripping

claws

268 and 270, and the support pin 200 is attracted to the pin storage hole 248 by a magnetic force and stored.

When the support pin 200 stored in the support pin storage device 244 is supported by the pin support plate 202, the support pin gripping head 250 is moved to the support pin storage device 244, and the support pin gripping device 252 is moved up and down. The support pin 200 is gripped and taken out from the pin storage hole 248. The support pin gripping head 250 is moved onto the pin support plate 202, the support pin gripping device 252 is moved up and down, the support pin 200 is placed on the pin placement position set on the support surface 226, and opened. The support pin 200 is fixed to the pin support plate 202 by a magnetic force.

The replacement of the component supply unit 330 will be described.
When there is no part 366 in the bulk feeder 300, the empty part supply unit 330 is replaced with a spare part supply unit 330 in which the part 366 is stored and stored in the unit storage base 672. Is replenished. The absence of the component 366 in the component storage chamber 364 is, for example, that the component 366 is not continuously removed for a set number of times even though the suction nozzle 100 performs the component removal operation for the same bulk feeder 300. It is detected based on that. Based on this detection, the mounting of the component 366 on the circuit board 40 is interrupted, and first, the empty component supply unit 330 having no component 366 is removed from the feeder main body 332 and stored in the unit storage base 672 for storing the empty unit. Is done.

At this time, the support pin gripping head 250 is moved to the empty component supply unit 330 by the mounting head moving device 52. The support pin gripping device 252 is lowered to the lower end position by the support pin gripping device lifting device 254 while being moved onto the gripped pin 630 of the component supply unit 330, and the gripping

claws

268 and 270 are closed to be covered. The gripped portion 636 of the grip pin 630 is gripped. After gripping, the support pin gripping device 252 is raised to the raised end position by the support pin gripping device lifting / lowering device 254, the component supply unit 300 is lifted, and the positioning pin 604 is removed from the positioning hole 606. After the pin to be gripped 630 is gripped by the gripping

claws

268 and 270, the energization direction to the electromagnet 620 is switched to the reverse direction before the support pin gripping device 252 is started to rise. As a result, a magnetic pole repelling the magnetic pole of the permanent magnet 622 is generated in the electromagnet 620, the component supply unit 330 is ejected from the feeder body 332, and the extraction of the positioning hole 606 from the positioning pin 604 is assisted. Further, the shutter 484 is located at the operating position, and the upper end portion of the drive plate 564 is pulled out from the recess 566, and the notch 570 is pulled out from the protrusion 568.

As the support pin gripping device 252 is raised, the component supply unit 330 is removed from the feeder main body 332 as shown in FIG. A drive motor 450 that is a drive source of the controller 660 and the component moving device 384 is attached to the feeder main body 332, and they are left in the feeder main body 332. After the support pin gripping device 252 is raised to the rising end position, the support pin gripping head 250 is moved toward the circuit board holding device 22 in the Y-axis direction by the mounting head moving device 52, and the gripped component supply unit 330 is held. The part after the part accommodating part 362 is positioned in front of the part accommodating part 362 and the gripped pin 630 of the part supply unit 330 of the adjacent bulk feeder 330 so that it does not interfere when moving in the X-axis direction.

In this state, the support pin gripping head 250 is moved in the X-axis direction and is moved to the unit storage base 672 for storing the empty unit. Then, among the plurality of holding units 682, the holding unit 682 that is actually vacant is moved to a position where the position in the X-axis direction matches the holding unit 682 farthest from the component supply device 24 in the X-axis direction. .

Note that the types and storage positions of electronic circuit components stored in the component supply unit stored in the unit storage unit are set in advance, and an operator places the component supply unit in accordance with the component supply unit storage data associated with them. You may make it accommodate in. In this case, the component information recording unit provided in the component supply unit can be used to check whether or not the component supply unit is stored as set in the component supply unit storage data. After storage, a component information recording unit, for example, a two-dimensional code is imaged by the reference mark imaging device for all the stored component supply units, and data on the actual storage position and the type of electronic circuit component is acquired, and the component supply It is compared with the unit storage data. At this time, if the correspondence between the storage position and the type of the electronic circuit component is incorrect, for example, the notification device notifies the operator of the fact and the storage is performed again. For example, the type and storage position of electronic circuit components that are stored incorrectly, and the type of electronic circuit components that are to be stored are notified.
Alternatively, the actual storage state may not be confirmed, and may be confirmed when the component supply unit is attached to the feeder body. After the unit holding head is moved to the storage position of the component supply unit to be attached to the feeder body according to the component supply unit storage data, the two-dimensional code is imaged on the reference mark imaging device prior to holding the component supply unit Let Thereby, the type of the electronic circuit component is acquired, and it is confirmed whether or not the electronic circuit component is to be supplied. In this case, if the type of the electronic circuit component is wrong, for example, a notification device notifies the user. Or you may make it search whether there exists the set electronic circuit component from the another component supply unit accommodated in the unit accommodating part. The two-dimensional code of another component supply unit is imaged by the reference mark imaging device, and the type of the electronic circuit component is acquired and searched. If not, the notification device notifies the fact. In any case, the wrong type of electronic circuit component is prevented from being erroneously mounted on the circuit board.

The driven rotating body and the driving rotating body of the rotary driving device constituting the component moving device of the component positioning device are each a rotating body provided with teeth on at least a part of the outer peripheral surface, and are engaged with each other to rotate the drive motor. May be transmitted to the driven rotating body. Alternatively, at least the outer peripheral surfaces of both rotating bodies may be made of rubber, which is a kind of high friction coefficient material, and rotation may be transmitted by friction on both sides. Many irregularities may be formed on the surface instead of the teeth.

Further, the bulk feeder in which the component automatic feeding and unloading device automatically attaches the component supply unit to the feeder main body and accommodates it in the unit accommodating portion is not limited to the bulk feeder 300, and is disclosed in JP-A-2009-105363. The bulk feeder described in Japanese Patent Publication No.) may be used.

The component supply unit may be provided with a unit identification information recording unit in which unit identification information capable of individually identifying the component supply unit is recorded. If the component supply units are individually identified, for example, the remaining number of electronic circuit components can be easily managed. For example, a component information recording unit is provided in the component supply unit together with a unit identification information recording unit, and the type of electronic circuit component and the initial accommodation number (when not used) are recorded. Here, it is assumed that the unit identification information recording unit and the component information recording unit can read information but cannot write or change information.
In a state where the component supply unit is attached to the feeder main body and is held by the feeder holding unit to supply the electronic circuit component, the unit identification information and the component information are acquired by the information acquisition device. Then, the number of electronic circuit components supplied is acquired for each component supply unit when the electronic circuit component is mounted on the circuit base, and the component is based on the number supplied and the initial number of electronic circuit components contained in the component information. A remaining number, which is the number of electronic circuit components currently housed in the supply unit, is obtained. The number of remaining parts is acquired by the computer of the electronic circuit component mounting machine and stored in the computer, and is also stored in the database when the component supply unit finishes supplying the electronic circuit components and is removed from the feeder body. Therefore, when the component supply unit is once removed from the feeder main body and then attached to the feeder main body again to supply the electronic circuit component, it is acquired from the database by the computer of the electronic circuit component mounting machine based on the unit identification information, The remaining number of parts that decreases with the mounting is monitored.
In addition, even if the component supply unit is stored in the unit storage unit outside the electronic circuit component mounting machine, it can be determined from the database information how many types of electronic circuit components are stored in which component supply unit, It is also possible to allow an operator to replenish electronic circuit components for a component supply unit with a small number of components, or to use the component supply unit for a usage plan.
Further, in a state where the component supply unit is not attached to the feeder body, the information acquisition device may acquire unit identification information and component information, and the unit / component information may be stored in a database or another personal computer. When the component supply unit is mounted on the feeder body, the unit identification information is acquired by the information acquisition device and input to the controller provided in the feeder body, and the unit identification information is transferred from the controller to the controller of the electronic circuit component mounting machine. Is to be supplied. The number of parts accommodated is obtained from the unit identification information and the previously acquired unit / part information, and can be used for managing the remaining number of parts.
Furthermore, the feeder main body may be provided with an identification information recording unit so that the feeder main body is individually identified.

Also, it is not indispensable to fix the component supply unit to the feeder main body or the unit storage portion by a fixing device including an electromagnet and a permanent magnet, and may be omitted. However, when the positioning protrusion of the positioning device is long and the fitting length with the positioning recess is large, an electromagnet and a permanent magnet are provided to project the component supply unit from the feeder main body and the unit housing. If the positioning protrusion is short and the positioning recess is shallow, the electromagnet and permanent magnet may be omitted. However, when the parts supply unit is mounted on the feeder body and supplies parts, It is desirable to provide a fixing device because the fitting is likely to come off due to vibrations such as.
