Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for supplying electric parts (including electronic parts) and an electric part mounting system, and more particularly to supplying electric parts by taped electric parts.

[0002]

2. Description of the Related Art A taped electric component is one in which the electric component is held at a constant pitch in the longitudinal direction of the tape and is held by a feeder to supply the electric component. The feeder includes a tape holding device and a feeding device, and the taped electric component is held by the tape holding device and is fed in the longitudinal direction by the feeding device to sequentially position the electric components in the supply unit.

When the electric parts are supplied as the taped electric parts as described above, for example, in the electric part supply device described in Patent Document 1, a plurality of feeders are mounted on a support base provided at fixed positions. , It is designed to supply electrical components in a stationary state. In this electrical component supply device, for each of the plurality of feeders, it is detected based on the number of the electrical components remaining in the feeder that it is necessary to replenish the electrical components and is notified. There is. Replenishment of electric parts is performed by connecting new taped electric parts to the taped electric parts which are currently supplying the electric parts. This connection work is performed by the operator. Since the electric component supply device is provided at a fixed position, the worker can perform the connecting work of the taped electric components even while the feeder is supplying the electric components. The notification that it is necessary to replenish the electric components is performed while the electric components remain in the feeder. In the electric component supply device, a notification is made before the occurrence of a component exhaustion in which at least one type of at least one type of electric component supplied by the electric component supply device is lost and an electric component that cannot be supplied is generated, and the electric component is replenished. Therefore, it is possible to avoid the situation in which the supply of the electric component is stopped due to the shortage of the component, and it is possible to improve the supply efficiency.

In addition, there is an electric component supply device in which a plurality of feeders are mounted on a moving table, and the feeding parts of the plurality of feeders are selectively positioned at the feeding positions by the movement of the moving table. In this supply device, for example, as described in Patent Document 2, a component supply table including a movable table and a plurality of feeders mounted on the movable table is 2
The stand is used to supply electrical components in three modes.

In the first mode, the kind or number of electric parts to be supplied is not so large, and all necessary feeders are 2
This is a mode in which it can be mounted on either one of the parts supply tables of the table. Therefore, the two parts supply tables each have the same type and number of feeders,
Alternately supply electrical parts. If a component shortage occurs during the supply of an electric component by one component supply table, the other component supply table supplies the electric component instead. In the second mode, since the types and number of electrical components to be supplied are large and it is not possible to mount all the feeders required for supply on a single moving base, it is mounted separately on each moving base of the two component supply tables. However, it is an aspect in which the electric parts are jointly supplied to the two parts supply tables. In the second mode, the two component supply tables are always moved integrally to supply the electric components, or at least one of the two component supply tables is moved to supply the electric components,
Electric parts are supplied by being moved integrally at the time of replacement of the parts supply table for supplying electric parts. The third mode is a mode in which the two component supply tables respectively have different targets for supplying electric components. Therefore, the numbers and types of feeders provided in the respective component supply tables are different from each other, and one of the two component supply tables corresponding to the target to which the electric component is supplied is moved to supply the electric component.

[0006] When the component supply table is moved in this way to supply the electric components, the replenishment of the electric components is performed with respect to the feeder in the stopped state without supplying the electric components. In the first mode, when a component shortage occurs, the component supply table for supplying the electric component is changed, and in parallel with the supply of the electric component, the electric component is replenished to the component supply table where the component shortage occurs. In the second mode and the third mode, if the parts run out, the supply of the electric parts is stopped and the electric parts are replenished. In either mode, for supplying the electric parts, for example, remove the feeder from the moving table, make the tape holding device of the feeder hold the new taped electric parts, and make it possible to feed by the feeding device. It is carried out by attaching it to a moving table. When the parts supply table is moved to supply the electric parts, the electric parts are not replenished by connecting the taped electric parts.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention, Problem Solving Means, and Effects However, in the component supply device described in the above-mentioned Patent Document 1, the operator takes measures against the notification that the electric components need to be replenished. If it is delayed, the supply of electric parts will not be completed in time, and the supply will have to be stopped.

Further, in the electric component supply device described in Patent Document 2, since the supply of the electric component is stopped and the electric component is replenished, there arises a problem that the supply efficiency is lowered. The electric components are supplied by the movement of the feeder. However, if the electric components need to be replenished, the movement of the feeder must be stopped and the supply must be stopped, which lowers the supply efficiency. In the case of the first mode, by alternating the two component supply tables, the supply is not stopped,
Electric parts can be supplied. However, for example, 2
If a plurality of feeders just before the electric parts run out are generated on each of the parts supply tables of the table, the table is changed frequently, and the electric supply is completed before the supply of the electric parts is completed on one of the parts supply tables. The other component supply table that supplies components may run out of components, in which case the supply of electrical components must be stopped. The problem of lowering the supply efficiency due to stopping the supply for replenishing the electric components also occurs when one or three or more component supply tables are provided.

In view of the above circumstances, the present invention has been made to solve the problem of improving the supply of electric parts by taped electric parts, and the present invention provides the electric part supply method and the electric parts of the following aspects. A component mounting system is obtained. Similar to the claims, each mode is divided into paragraphs, each paragraph is numbered, and the numbers of other paragraphs are referred to as necessary. This is merely for facilitating the understanding of the present invention, and the technical features and combinations thereof described in the present specification should not be construed as being limited to those described in the following respective sections. . Moreover, when a plurality of items are described in one section, it is not always necessary to adopt the plurality of items together. It is also possible to select and use only some of the items.

In each of the following items, (1) corresponds to claim 1, (2) to claim 2, and (7) to claim 3.
(8) corresponds to claim 4, (9) corresponds to claim 5, (10) corresponds to claim 6, and (11) corresponds to claim 7.

(1) A tape holding device for holding the taped electric parts in which the electric parts are held at a constant pitch in the longitudinal direction of the tape so as to be pulled out from the tip side, and the taped electric parts pulled out from the tape holding device. A plurality of feeders, each of which has a feeding device that feeds in the longitudinal direction and sequentially positions electric components in the supply unit, are mounted on a moving table in a state where the supplying units are aligned along a line, and the moving table is arranged in the line. An electric component supply method using an electric component supply device that sequentially positions the supply units of the feeders at predetermined supply positions by moving the feeders, and sequentially supplies the electric components at the supply positions. In at least one of the feeders of the above, connect the tip of a new taped electrical component to the end of the taped electrical component, and follow the previous taped electrical component. EC supplying method for supplying the electrical components of the new tape of electrical components.

The taped electrical component is, for example, the taped electrical component described in item (7), in which the electrical component is housed in the housing recess, or the lead of the electrical component is held by the tape. To be taken. The line along which the supply units of the plurality of feeders are arranged may be, for example, a straight line, a curved line (including a circular arc), or a combination thereof. Further, the positions of the respective supply units of the plurality of feeders do not necessarily have to coincide with the line and may deviate from the line. As the tape holding device, various types of devices can be adopted. For example, as will be described later, the tape holding device may be a device that includes a reel holding portion and holds the taped electrical component wound around the reel, or the tape storage case. It is also possible to adopt a device that includes the above and that folds and stores the taped electrical component from the tip side. When the tape holding device includes a reel holding unit, the reel holding unit includes, for example, a plurality of rollers serving as a support rotating body or a support shaft. When connecting a taped electric component (referred to as the previous taped electric component) that was used to supply electric components up to that time and a new taped electric component, the moving base is in a stopped state, but the tape If the electric parts are replenished by connecting the electric parts, it is possible to reduce the number of supply interruptions for stopping the supply of the electric parts in order to replenish the electric parts.
Alternatively, it is not necessary to stop the supply, and the supply efficiency can be improved. If the electric parts are replenished by connecting the taped electric parts, the former taped electric parts can be replenished while remaining in the feeder, and the electric parts remaining in the taped electric parts can be used. . When removing the taped electric parts from the feeder to replenish the electric parts, if the electric parts are replenished while the taped electric parts remain, the remaining electric parts will be discarded. On the other hand, when it is wasteful, if the taped electric component is connected, the electric component can be replenished without waste. Therefore, not only the feeder that has run out of parts, but also the feeder that has a small amount of remaining electric parts and will run out of electric parts in the near future can be connected with taped electric parts and replenished with electric parts. It is possible to avoid running out of electric parts during supply in the parts supply device, do not have to stop the supply, or the probability of running out of electric parts during supply decreases and the number of supply interruptions decreases, improving work efficiency. Can be done. This is the same regardless of whether the number of mobile units is one or more. In addition, the shortage of parts in the feeder means that there is no electric component to be supplied in one feeder, and the shortage of parts in the electric component supply device is
That is, at least one type out of a plurality of types of electrical components supplied by the electrical component supply device disappears. Therefore, when the types of electric components held by the plurality of feeders included in the electric component supply device are different from each other, the component out of the feeder is the component out of the electric component supply device, and the feeder that supplies the same type of electric component is When a plurality of feeders that supply the same type of electric components are used up, the electric component supply device is out of parts because all of the feeders have no electric parts. If the feeder is out of parts,
The case is not limited to the case where the number of electric components held by the feeder is 0, and the case where the electric components remain but may be substantially eliminated is also included. For example, on the upstream side in the feeding direction of the taped electrical component with respect to the feeder of the feeder,
If the end of the taped electrical component is detected by the end detection device at a position close to the supply unit, it is considered that the component has run out. This is because even if there are electrical components left in the feeder, they are very small. In any case, if the electric parts are replenished by connecting the taped electric parts to the parts shortage feeder, the parts shortage is detected with the taped electric parts long enough for the connecting work remaining in the feeder. To be done. This part may or may not contain electrical components. In this case, it can be said that the component shortage feeder is a feeder in which the taped electrical components cannot be connected if the electrical components are further supplied. For the feeder that has run out of parts, the electric parts may be replenished by means other than the connection of the taped electric parts. For example, a feeder that has run out of components is replaced with a feeder that holds electric components of the same type. In this case, the taped electric component having a length necessary for connection does not have to remain in the feeder, and for example, the taped electric component can be disconnected when the end of the taped electric component reaches the vicinity of the supply portion. Even with such a parts-out feeder, when supplying electric parts based on the detection, the tape-shaped electric parts are connected to the feeders that are likely to run out of electric parts in the near future. Can be reduced.

If the electric parts are replenished by connecting the taped electric parts as described above, the electric parts are supplied by using two parts supply tables as described above. When supplying electric parts by mode, there is a possibility that there will be no electric parts in the comparatively near future while the next electric parts are being supplied in the parts supply table that is not in operation, and is in a resting or retreating state. By connecting the taped electric parts to the feeder with high
It is possible to prevent the parts from running out or a plurality of feeders close to the parts to run out at the same time, so that the supply of the electric parts to the table which is not in operation cannot be supplied in time and the supply is not stopped or reduced. In the second mode, when the two component supply tables always move integrally to supply the electric component, if one of the electric components runs out of components, the supply is stopped and the electric component is stopped. Parts will be replenished, but at that time, in addition to the feeder that has run out of parts, if there is a feeder with few remaining electric parts, by connecting the taped electric parts to that feeder as well, It is possible to avoid the occurrence of parts shortage that should have occurred in the feeder, and the number of stoppages can be reduced. In the second mode, when the two component supply tables are integrally moved only at the time of replacement, among the feeders of the component supply table in the idle state, the feeder that is almost out of parts is fed with the taped electric component. By making the connection, it is possible to reduce the number of stoppages for supply. When supplying electrical parts in the third mode,
The number of stoppages can be reduced by connecting the taped electric parts to the feeders of the parts supply table which are not in operation, which are more likely to run out of parts during supply. In this way, if there are multiple parts supply tables, it is possible to connect the taped electric parts in parallel with the supply by putting at least one of them in the dormant state, and avoiding or reducing the supply interruption. Is easy. However, even when there is only one component supply table, or when a plurality of component supply tables simultaneously move integrally to supply electric components, when component shortage occurs, component shortage still occurs. Although it has not occurred, but for feeders that are likely to run out of parts in the near future, connecting taped electrical parts together at the same time reduces the occurrence of parts out during supply and reduces the number of supply interruptions be able to. The taped electrical components may be connected with the feeder still attached to the moving table or may be removed from the moving table. In the latter case, the feeder to which the taped electric parts are connected may be returned to the moving table to supply the electric parts, or may be put on standby in preparation for the next supply. The connection of the taped electric parts may be made not only to the feeders currently supplying the electric parts but also to the feeders not used for the supply. For example, the replenishment of electric parts may be performed by replacing the feeder, and in that case, the taped electric parts are connected to the feeder removed from the moving table. Feeder replacement is done for out-of-parts feeders and feeders that are likely to run out of electrical components in the near future,
Replace the feeders with a feeder that holds the electrical components well. The taped electric parts are exchanged together with the feeder, and the taped electric parts are connected to the feeder in which the electric parts remain, and the electric parts are replenished without wasting the electric parts. By connecting the taped electrical parts, it is possible to replace the feeders that are close to running out of parts and replace them with feeders that sufficiently hold the electrical parts, and replenish the electrical parts. The occurrence of parts shortage during supply is reduced, and the supply efficiency is improved. When electric parts are replenished by replacing the feeders, if the feeders are taped and the electric parts are dedicated, the number of feeders required is twice the number mounted on the moving table. For example, different types of feeders are taped. 1 if it can hold electrical components
By sharing one feeder for a plurality of types of taped electric components, it is possible to reduce the number of feeders and suppress an increase in equipment cost. In this case, for example, if the taped electrical component is held on the reel, the reel is removed from the feeder removed from the moving table, and the same type of taped electrical component held on the detached reel is taped. A feeder that supplies electrical components, and when a feeder that is currently supplying electrical components is notified or informed that there will be no electrical components in the near future, the reel will be connected to taped electrical components based on the notification. And set it in the empty feeder so that it can be exchanged with the feeder set in the moving table. By removing the reel from the feeder when the electric component is not supplied, the feeder can be used for supplying the electric component held by another reel, and the feeder is shared and the number of the feeder can be reduced. . The connection of the taped electric parts may be performed in advance before the advance notice of the parts running out. In this way, when connecting the taped electric parts with respect to the taped electric parts in the state where the taped electric parts are detached from the feeder, the taped electric parts are held by the feeder and supply the electric parts. Is a connection.

(2) The plurality of feeders are mounted on a pallet, the pallet is removably mounted on the moving table to supply electric parts, and the tape-forming electricity is removed with the pallet removed from the moving table. Connecting the components The method for supplying electrical components described in (1). By attaching and removing the pallet to and from the moving table, a plurality of feeders are attached to and removed from the moving table all at once. According to this section, for example, the plurality of feeders removed from the moving table can be easily moved to a place suitable for work, for example, a large place or a storage place for new taped electric parts, so that work can be performed efficiently. can do. (3) The electric component supply method according to item (1), in which the plurality of feeders are directly mounted on a moving base, and taped electric parts are connected to the feeders on the moving base. In this section, the taped electrical components are connected while the feeder is still attached to the moving table. (4) Prepare a plurality of the moving bases, supply at least one feeder of the plurality of moving bases with electric parts, and save another at least one in the save area,
The electrical component supply method according to item (2) or (3), wherein the taped electrical component is connected to the feeder of the moving base during the evacuation. Here, the "feeder of the moving base during the evacuation" may be a feeder that is still mounted on the moving base that is evacuated to the evacuation area, or may be a feeder that is removed from the moving base that is evacuated to the evacuation area. In parallel with the connection of the taped electric parts, the electric parts can be supplied by the feeder of the moving table different from the moving table being evacuated, and the decrease in work efficiency can be favorably avoided.

(5) When the worker is connecting the taped electric parts to the feeder of the moving table in the saving area, it is necessary to move the moving table from the saving area. If it occurs in the device, the alarm device notifies the operator of the fact by the method (4). In the above-mentioned "when it is necessary to move the mobile stand from the retract area in the electric component supply device", for example, when the mobile stand needs to be moved immediately (referred to as a notification without grace). Before moving to a state where it is necessary to move the mobile stand immediately,
In this case, there is a case (referred to as advance notification) in which there is time for the worker to finish the connection work being performed and put the mobile table in a movable state in response to the notification from the notification device. In any case, the worker finishes the work based on the notification from the notification device, and puts the mobile table in a state where the mobile table can be moved from the retracted area. In the case where the advance notification is made, in principle, the mobile base can be moved from the evacuation area without delay and even if the mobile base is delayed for some reason. The advance notification is, for example, such that advance notification is made at a time point set back from the end of parts supply by the parts supply table currently supplying parts or the start of parts supply by the parts supply table in the save area. can do. It is desirable that the set time is, for example, a time sufficient for the worker to finish the connection work of the taped electric components and move the moving table from the retracted area.
Alternatively, advance notification may be performed when the number of feeders (including 1) capable of connecting the taped electric components is exceeded, or the time until the parts run out for each feeder occurs. It may be performed when a certain remaining time is obtained and the number of feeders that are connectable feeders and the remaining time is equal to or less than the set time exceeds the set number (including 1). Only the notification without grace may be performed, only the advance notification may be performed, or both of them may be performed. (6) When the worker is connecting the taped electric parts to the feeder of the moving table in the shelter area, the electric parts are supplied unless the worker inputs the movement approval information into the input device. The method for supplying electric parts according to item (4) or (5), wherein the device cannot move the moving base during the evacuation. The input device may include, for example, a key device in which various keys are provided and data is input by an operator performing a key operation, or the input device is always connected with the completion of the connecting work of the taped electrical parts. The operated device may be the input device. In the latter case, for example, the entire moving area of the moving table is covered by the cover, and when the worker works on the feeder of the moving table moved to the retract area, the opening / closing cover provided on the cover. When the opening / closing operation is performed, it is possible to input the movement approval information that the connection of the taped electric parts is completed and the opening / closing cover is closed. The open / close cover constitutes the input device. According to this section, it is possible to avoid the movement of the movable table in a state that the operator does not intend, such as during the tape connecting work.

(7) As the taped electric component, a carrier tape having accommodating recesses formed at a constant pitch in the longitudinal direction, electric components accommodated in each accommodating recess, and accommodating by being attached to the carrier tape. A cover tape that covers the recess is used, and the cover tape peeled from the carrier tape is housed in the housing case. When a predetermined amount of the cover tape is housed in the housing case, the cover tape is taken out from the housing case. The electrical component supply method according to any one of (1) to (6). The housing case may be made of, for example, a colorless transparent material or a colored transparent material so that the operator can visually check the housing amount of the cover tape from the outside, and a sensor is provided to detect the housing of a predetermined amount of the cover tape. You may do it. If the cover tape is stored in the storage case, the cover tape can be taken out with the feeder still attached to the moving table, and the cover tape peeled from the carrier tape can be easily and quickly processed. You can Since the work of connecting the taped electric parts can be performed without removing the feeder from the moving table, housing the cover tape in the housing case is suitable for supplying the electric parts by connecting the taped electric parts. It is not essential to store the cover tape in the storage case, but the cover tape may be wound around the winding reel. For example, when replenishing electric parts for a feeder that can be connected to a part-out feeder and taped electric parts by replacing the taped electric parts with the feeder, the taped electric parts are removed from the feeder removed from the moving table. In addition to the above connection, the take-up reel is removed from the feeder main body, the wound cover tape is removed to make it empty, and the cover tape is wound again by setting it on the feeder. When the cover tape is stored in the storage case, the storage case may be shared by a plurality of feeders. The features described in items (8) to (27) are also applicable to the electrical component supply method described in items (1) to (7).

(8) (a) A tape holding device for holding the taped electric parts in which the electric parts are held at a constant pitch in the longitudinal direction of the tape so as to be drawn out from the tip side, and (b) drawn out from the tape holding device. A plurality of feeders, each of which is provided with a feeding device for feeding the taped electrical component in the longitudinal direction and sequentially positioning the electrical component in the supply portion, and the electrical component mounted on the table in a state where the supply portions are aligned along a line. A supply device,

And a pointing device for pointing a connectable feeder capable of connecting the tip of a new taped electrical component to the end of the electrical component mounting system. The above “line” is explained in the same manner as in item (1). The circuit board may be, for example, a printed wiring board on which no electrical components have been mounted yet, a printed wiring board on which electrical components have been mounted on a part of the printed wiring, or an electrical component on one of both sides that has already been soldered. There are a printed circuit board to which attachment and joining are performed, a printed circuit board fixed by an adhesive, and a small circuit board on which a small number of electric parts are mounted. The mounting device includes, for example, (a) a plurality of component holding devices, and these component holding devices are swung around a common swivel axis by a component holding device swivel device, which is a type of component holding device moving device, It may be a device that sequentially stops at a plurality of stop positions to receive the electric components from the electric component supply device and mount them on the circuit board. (B) At least one component holding device is provided, and the component holding device is moved. The device moves the component holding device in a direction having two orthogonal components in a moving plane parallel to the surface of the circuit board, and moves it to an arbitrary position in the moving plane to receive and mount the electric component. (C) at least one component holding device, and by the component holding device moving device, each other in a moving plane parallel to the surface of the circuit board. Or as a device for linearly moving the component holding device in one of the interlinking two directions. When the mounting device is of type (a), the substrate holding device
The substrate holding device moving device translates in a direction having two orthogonal components in a moving plane that is a plane parallel to the surface of the circuit board, and in the electric component supplying device, a plurality of feeders are mounted on a moving table. The moving table is moved by the moving table moving device along a line along which the supply units of the plurality of feeders are arranged. The mounting device is (b)
In this type, the substrate holding device and the electric component supply device are fixedly mounted and are stationary. When the mounting device is of the type (c), the board holding device is moved by the board holding device moving device in two directions orthogonal to each other in a moving plane that is a plane parallel to the surface of the circuit board.
The component holding device can be linearly moved in a direction different from the moving direction. The electric component supply device may be provided in a stationary state with the supply unit positioned within the movement trajectory of the component holding device, the feeder is mounted on the moving table, and the moving table is moved by the moving table moving device. It may be made to be able to move along a line lined up along it. The component holding device turning device, the component holding device moving device, and the board holding device moving device constitute a relative moving device that relatively moves the component holding device and the board holding device in a direction parallel to the surface of the circuit board. When the mounting device is moved along a movement plane or a straight line, a movement different from the movement may be additionally performed. For example, a rotary disk (eg, an intermittent rotary disk) that holds and rotates a plurality of component holding devices is further translated by a moving device in a direction having two orthogonal components in a moving plane and rotated. The component holding device may be moved to the mounted position where the electric component on the surface of the circuit board is mounted by a combined motion of rotation and parallel movement of the board. in this case,
The axis of rotation of the turntable may be perpendicular to the plane of movement or may be inclined. Further, on the turntable, the component receiving position where the component holding device receives the electrical component from the electrical component supply device and the component mounting position where the electrical component is mounted on the printed board may be the same or different. The pointing device is
It is configured in various ways. It may be an instruction device that directly instructs the connectable feeder or an instruction device that indirectly instructs the connectable feeder. The indicating device should be able to know the display device and data relating to the connectable feeder to the display device, for example, the type of electric parts supplied by the connectable feeder, the mounting position of the feeder on the table, and the remaining number of parts in the feeder. For example, a connectable feeder display control unit that displays the number of remaining components and the like may be included. The connectable feeder is a feeder that does not cause any trouble even if a new taped electrical component is connected to the taped electrical component that is currently supplying the electrical component, and it is possible to connect because the remaining electrical components are few. . Therefore, by connecting the taped electric components to the connectable feeder, it is possible to avoid or reduce the occurrence of component shortage during component supply. When the connectable feeder is instructed, the worker can know which of the plurality of feeders is the connectable feeder and the like, and can perform the connecting work quickly and accurately. If the feeder is mounted on a feeder support table that is fixed in position and supplies electrical components, the connectable feeder is instructed to supply the electrical components earlier. As compared with the conventional case where the replenishment of the electric component is performed based on the notification that the replenishment of the electric component is necessary, a situation in which the replenishment of the electric component may not be in time due to the delay in handling by the worker may occur. Avoided and reliability of supply is improved. If the feeder is mounted on a mobile stand and supplies electric parts by moving the mobile stand, the connectable feeder is instructed so that the tape is taped when the mobile stand comes to the save area. The electric parts can be connected, or when the number of connectable feeders reaches an appropriate number, the movable table can be retreated to the retreat area and the taped electric parts can be connected. Further, it is not essential to connect the taped electric components to all the connectable feeders, and the feeder to be connected can be determined based on the instruction from the instruction device. The degree of freedom in deciding when to execute the connection is increased, and the taped electric parts can be connected at a time when the work efficiency is little affected.

For example, the feeder determining unit determines that the remaining tape amount, which is the amount of taped electrical components actually held in the tape holding device, is the maximum amount of taped electrical components that the tape holding device can hold. When the capacity is 30% or less, 20% or less, 15% or less, 10% or less, or 5% or less, the feeder including the tape holding device can be determined as the connectable feeder.

The taped electrical component before the new taped electrical component is connected is wound around the reel on which the new taped electrical component is wound, but there is a limit to the amount of taped electrical component that can be wound on that reel. The possible amount is determined. If the new taped electrical component is wound around the reel to a position retracted from the outer peripheral surface of the reel to the rotation axis side, the gap between the outer peripheral surface of the new taped electrical component and the outer peripheral surface of the reel is wrapped. I can afford it. If the taped electrical component can be wound around the reel by protruding outward from the outer peripheral surface of the reel in the radial direction, the winding allowance is the outermost surface of the new taped electrical component wound on the reel and the most protruding portion. The gap between the taped electric component and the surface on which the outer peripheral surface of the taped electric component is located becomes a winding allowance. In the latter case,
It is not indispensable that the maximum winding position of the new taped electric component is a position retracted from the outer peripheral surface of the reel.

The remaining time is the time required for all the scheduled electrical components to be mounted on all of the at least one circuit board to which the electrical components can be supplied by the feeder by the electrical components remaining on the feeder, For example, the integer obtained by dividing the number of remaining components by the number of electrical components taken out to perform the mounting work on one circuit board and rounding down the fraction is the number of circuit boards capable of supplying electrical components. This number corresponds to the time when electrical components are mounted, and the remaining time may be determined by the number of
Alternatively, the remaining time may be obtained by multiplying the time required for the work of mounting all scheduled electrical components on one circuit board by the number of sheets. If the remaining time is obtained, the connectable feeder can be determined more accurately. Even if the actual amount of taped electrical components remaining in the feeder is large (for example, remaining length or number of remaining components), if the number of electrical components supplied to one circuit board is large, the number of electrical components will decrease rapidly.

It is a time that can be wound up without protruding the part from the reel to a new taped electric part, and of course the occurrence of parts shortage is avoided and the holding amount of the taped electric part by the tape holding device is reduced. The time is set so that it will not be overkill. When the remaining time is acquired by the number of circuit boards, the set number is used instead of the set time. The set number of sheets is set similarly to the set time.

In the electronic component mounting system 12 of the present embodiment, the mounting of the electronic component 140 on the printed wiring board 30 is performed according to one of the following three modes. In the first mode, the type or number of electronic components 140 mounted on one printed wiring board 30 is not so large, and all the necessary feeders 130 are provided on the moving bases 134 of the first and second component supply tables 120 and 122. This is performed when it can be mounted on any one of the (pallets 132). Therefore, the two parts supply tables 120, 12
The feeders 130 of the same type and number are mounted in the same arrangement on each of the two moving bases 134 (pallets 132).

The order in which the feeders 130 are mounted is set in advance, and the order in which the electronic components 140 are mounted on the printed wiring board 30 may be different or may be different, but in any case, they are set in advance. In this embodiment, they are mounted in the order of mounting. Further, in the illustrated example, one moving table 134
It is assumed that the types of electronic components 140 held by the plurality of feeders 130 mounted in each are different. These are the same for the second and third modes. Therefore, in the present embodiment, “parts out” means that a plurality of types of electronic components 14 are supplied by one component supply table.
0 means that any one of the electronic components 140 is gone, and that one of the plurality of feeders 130 supplies no electronic component 140.
In the present embodiment, it is considered that when the electronic components 140 are substantially removed from the feeder 130, the components run out. As will be described later, when the end of the tape-shaped electronic component 142 is detected by the tape end detection device 290, a component shortage is detected, and the feeder 1 is detected when the component shortage is detected.
This is because the electronic component 140 still remains in the part 30, but it is small, and the electronic component 140 may substantially disappear.

In the first mode, one of the two parts supply tables 120 and 122 is moved to the parts supply area to supply electronic parts, and is made to function as a production table or an operation table, and the other is the save area. Therefore, it is used as a refuge table or a spare table. Regarding the save table, the electronic parts 140 are replenished, the production table and the save table are replaced when the parts in the production table run out, and the save table becomes the production table to supply the electronic parts 140, The production table serves as a refuge table and the electronic components 140 are replenished.

In the second mode, the type or number of electronic components 140 to be mounted on the printed wiring board 30 is large, and each of the movable bases 1 of the first and second component supply tables 120 and 122 is used.
It is not possible to mount all of the necessary feeders 130 with only one of the first and the second carriages 34, so that the feeders 130 are separately mounted on the two movable bases 134, and the first and second component supply tables 120, 122 are provided.
This is a mode in which the electronic components 140 are supplied jointly by. In this case, the first and second component supply tables 120 and 122 are regarded as one component supply table,
In the present embodiment, the electronic components are alternately moved to the component supply area so as to be supplied in the order of mounting on the printed wiring board 30. The first and second component supply tables 120 and 122 are
One side is always moved and the first component supply table 12
The second component supply table 122 is moved to the component supply area shortly before the end of the supply of the electronic component 140 by 0, and the first component supply table 120 is replaced only at the replacement time.
And the first component supply table 120 finishes the supply of the electronic component 140, and the first component supply table 120 is moved to the save area and then moves independently to supply the electronic component 140.

In the third mode, the type and number of electronic parts supplied to one printed wiring board are not so large,
The required electronic components 140 can be supplied by the feeder 130 mounted on one component supply table, but the type of the printed wiring board 30 changes frequently, and the two component supply tables 120 and 122 have different components. Table 12
0 and 122 are the modes in which the feeder 130 corresponding to the type of the printed wiring board 30 that supplies the electronic component is mounted, and the table that supplies the electronic component 140 alternates every time the type of the printed wiring board 30 changes.

In the third mode, there are, for example, two types of printed wiring boards 30, and the number of consecutively mounted printed wiring boards 30 of each type is relatively small, so that there are two types of printed wiring boards. The electronic components 140 are mounted on the board 30 alternately for each set number of printed wiring boards 30.
The component supply table is changed every time the type of the component is changed, but the two component supply tables are replaced by the electronic components 140, respectively.
The type of the printed wiring board 30 that supplies the same does not change, the type of the feeder 130 that is mounted on the component supply table does not change, and there are three or more types of the printed wiring board 30. Electronic components to 14
Every time the mounting of 0 is completed, the parts supply table displays electronic parts 1
There is a mode in which the type of the printed wiring board 30 that supplies 40 is changed and the mounted feeder 130 is changed according to the type of the printed wiring board 30.

The three component mounting modes that can be executed by the electronic component mounting system 12 are selectively performed based on the operator's instruction, etc., but the first mode is often executed. Electronic component 14 according to the first mode
The mounting of 0 on the printed wiring board 30 will be described.

Then, the image pickup data is subjected to image processing, and a holding position error of the electronic component 140 by the suction nozzle 90 is calculated. The image data of the electronic component 140 obtained by imaging is compared with the normal image data having no holding position error, and the center position errors ΔXE and ΔYE and the rotational position error Δθ are obtained as holding position errors. The center position error is
As described above, this is the translational position error, and the electronic component 140
This is a positional error in the plane perpendicular to the axis of the suction nozzle 90 with respect to the central suction nozzle 90, and also in the horizontal movement plane of the printed wiring board 30. The rotational position error is a position error of the electronic component 140 around an axis line that is perpendicular to the surface to be sucked by the suction nozzle 90. After that, if the component holding device 70 is moved to the component posture correction position, the suction nozzle 90
Is rotated about its own axis, and the rotational position error Δθ of the electronic component 140 is corrected.

When the component holding device 70 reaches the component mounting position, the suction nozzle 90 is lowered to place the electronic component 140 on the surface 60 of the printed wiring board 30 and release the electronic component 140. It is mounted on the printed wiring board 30. The printed wiring board 30 is moved by the XY table 32, and the mounted position is positioned at a position corresponding to the component mounting position of the mounting device 16. At this time, the moving distance (moving position) of the printed wiring board 30 is corrected, and horizontal position errors ΔXP, ΔYP of the mounted position, the electronic component 14 are corrected.
0 center position error ΔXE, ΔYE and rotational position error Δ
The electronic component 14 in the horizontal plane caused by the correction of θ

If a component shortage occurs in the component supply table that is supplying 0, the component supply table is saved in the save area, and another component supply table saved in the save area is moved to the component supply area instead. Then, the electronic component 140 is supplied.

In the present embodiment, the end of the tape-shaped electronic component 142 is the end-of-tape detecting device 29 when the component is out.
It is detected by being detected by 0. The tape end detecting device 290 constitutes an end detecting device or a component shortage detecting device. For example, when the first component supply table 120 supplies the electronic component 140 in the component supply area and the second component supply table 122 saves in the save area, it is assumed that the first component supply table 120 runs out of components. For example, the first parts supply table 12
0 is moved to the save area and the second component supply table 122 is moved to the component supply area. Then, while the second component supply table 122 supplies the electronic component 140, the electronic component 140 can be replenished and connected to the first component supply table 120, which is the retracted component supply table, by replacing the component shortage feeder. The taped electronic components 142 in the feeder are connected, that is, spliced, and the electronic components 140 are replenished.

To the end portion of the taped electronic component 142 of the carrier tape 144 of No. 1, the tip portion of the taped electronic component 142 of the carrier tape 144 of the new taped electronic component 142 is connected by the tape connecting member 300. The cover tape 146 of the electronic component 142 is attached to the terminal portion of the electronic component 142 of the tape.
2 is connected by a connecting tape 316, and the portion of the previous taped electronic component 142 removed from the reel 150 is wound around a new taped electronic component 142 and held on the reel 150, and the new taped electronic component 142 is held. The reel 150 holding the component 142 is set on the feeder 130. This connecting work is performed in the work place, and the pallet with a feeder 326 is placed on the workbench 500. Therefore, in the first component supply table 120 that has been evacuated to the evacuating area, after stopping, the feeder 130 together with the pallet 132 is removed from the movable table 134 and transferred to the dolly 502, and then transferred to the work table 500 provided in the workshop. The tape-shaped electronic components 142 are transported and connected on the workbench 500.

The dolly 502 is connected to the bed 10 by the dolly connecting device 680 when receiving the pallet with feeder 326 from the component supply device 18. Dolly 502
Can be connected to the bed 10 even when the opening / closing cover 472 or 474 remains closed. When connecting the dolly 502 to the bed 10, the operator holds the handle 568 to move the dolly 502, and the pair of engaging members 620 is engaged.
And with the pair of cams 652 provided on the bed 10 aligned in the horizontal direction, the carriage 502 is moved forward,

The dolly 502 has the height of the pallet support table 510 prior to being connected to the bed 10, and the support table elevating device 51.
2, the engaging member 620 is just placed on the horizontal surface 658 of the cam 652 and is positioned below the height at which the engaging member 620 is supported from below.
22 is positioned at a height where it can engage with the inclined surface 656 (see FIG. 20) of the cam surface 654. In that state, the lateral position of the pair of engaging members 620 is aligned with the cam 652, and the cam 652 guides the lateral position,
It is guided into the cover 470. In addition, the support platform lifting device 51
When the height of the pallet support base 510 is adjusted by 2, the operator operates the handle 534 to rotate the four levers 520 to move the pallet support base 510 up and down, and the lower end edge of the cover 552 of the pallet support base 510. But the cover 550
A predetermined value of the scale 554 (see FIG. 13) provided on the above is indicated.

Therefore, when the roller 622 is advanced along the inclined surface 656, the front part of the pallet support table 510 is lifted up with respect to the rear part, and the engaging member 620 causes the cam 6 to move.
It is guided by 52 and moved forward. The fitting hole 528 on the front side of the pallet support base 510 is made longer than the fitting hole 528 on the rear side, and the front part of the pallet support base 510 connects the upper end surface of the rear fitting hole 528 and the roller 622. The contact portion is lifted around the fulcrum, and the carriage 502 is allowed to move forward.

As shown in FIG. 20, the carriage 502 is advanced until the vertical contact surface 624 provided at the base end of the engaging member 620 contacts the cam 652. Due to this abutment, when the carriage 502 is stopped, the engaging member 620 is placed on the horizontal surface 658 of the cam surface 654 and supported from below, and the roller 622 is slightly above the inclined surface 660. It will be located. In this state, the operator operates the handle 534 to rotate the four levers 520 to raise the rear portion of the pallet support table 510.

The lever 520 is rotated until the roller 526 provided on the front lever 520 comes into contact with the upper end surface of the fitting hole 528. Rotation of the rear lever 520 raises the rear portion of the pallet support base 510,
The height of the front portion and the rear portion of the pallet support table 510 is the same and is horizontal. The operator also uses the scale 5 provided on the rear surface of the cover 550 that covers the frame 508 of the carriage 502.
While looking at 54, the handle 534 is operated, and the height of the pallet support table 510 can be known from the value of the scale 554 indicated by the lower end of the cover 552 provided on the pallet support table 510. Therefore, even if it is difficult to obtain a feeling of contact between the roller 526 and the end surface of the fitting hole 528, if the handle 534 is operated until the scale 554 shows a preset value, the carriage 502 engages with the bed 10. A state in which the pallet support table 510 is horizontal is obtained. If the operator stops the operation of the handle 534, the screw shaft 538 does not rotate,
The pallet support table 510 has a predetermined height, that is, the height of the support roller 560 is raised to the rising end position of the component supply device 18, and the support roller 404 of the pallet support table 328.
The height of the guide roller 460 is the same as the height of the guide roller 460, and the pallet delivery position of the component supply device 18 is maintained in the vertical direction.

If the abutment surface 624 of the engaging member 620 abuts the cam 652 and the carriage 502 is stopped, as shown in FIG. 20, the groove 626 of the engaging member 620 is below the engaging pin 666. Will be located in Then, the engagement pin 666 is lowered by the pin driving device 668 and fitted into the engagement groove portion 630 to prevent the engagement member 620 from being detached from the inside of the cover 470, so that the carriage 502 moves to the bed 1.
It is connected immovably to 0. The fitting of the engaging pin 666 into the engaging groove portion 630 is guided by the inclined surface of the groove side surface 628. Further, even if the engagement groove portion 630 of the groove 626 and the engagement pin 666 are slightly displaced in the pallet transfer direction or the movement direction when the carriage 502 is connected, the engagement pin 666 is absorbed by the swing. The engaging pin 666 fits into the engaging groove 630.

As described above, the carriage 502 is provided with the engaging member 620.
Through the opening 640 into the cover 470, and the engaging pin 666 is engaged to prevent the disengagement from connecting with the bed 10.
The dolly 502 can be connected to the bed 10 without opening 74. Therefore, the cart 502 can be connected to the bed 10 not only when the component supply device 18 is not supplying the electronic component 140 but also during the supply. If the dolly 502 is connected to the bed 10, the pallet with feeder 326 can be immediately transferred to the dolly 502 if the parts supply table is moved to the save area.

If a component shortage occurs in the component supply table, the alarm 732 gives a notification and
Displayed on the display screen 734. The display screen 734 displays the component supply table in which the component is out, the type of the electronic component 140 in which the component is out, the mounting position of the feeder 130 that supplies the electronic component 140 to the pallet 132, and the like. If the dolly 502 is connected to the bed 10 at the time of running out of parts, the operator opens the opening / closing cover on the side of the saving area where the parts supply table has been saved according to the display on the display screen 734, and the pallet 326 with the feeder. Are transferred to the dolly 502. If the carriage 502 is not yet connected to the bed 10, the opening / closing cover is opened after being connected.

The feeder pallet 326 is supported from below by a support roller 560, and a pair of guide rails 56 are supported on the support roller 560.
It is moved while being guided by 2, and is moved until it comes into contact with the stopper 570.

At this time, the rear end surface of the pallet 132 engages with the inclined surface 610 of the plunger 582 of the locking device 580,
The action of the slope causes the plunger 582 to move to the spring 604.
The pallet with a feeder 326 is allowed to move by retracting it toward the fitting hole 584 side against the biasing force of. Pallet 132
Is brought into contact with the stopper 570 and stopped,
The locking hole 616 provided in the pallet 132 is in a state of facing the plunger 582, the plunger 582 is projected from the fitting hole 584 by the urging force of the spring 604, and the tip end thereof is fitted into the locking hole 616. .
As a result, as shown in FIG. 19, the locking surface 612 provided on the plunger 582 becomes the locking surface 618 of the locking hole 616.
The pallet 132 is prevented from moving in the pallet transfer direction or the front-back direction by the engagement of the locking surfaces 612 and 618 and the contact of the pallet 132 with the stopper 570, and the pallet 132 is locked to the carriage 502. It Also, pallet 1
The 32 clamped portions 410 reach below the holding portion 572 provided on the carriage 502, and the lifting is prevented. The pallet 132 is positioned by the pair of guide rails 562 in the supply unit arranging direction.

After the pallet with feeder 326 is transferred to the dolly 502, the engaging pin 666 is raised to be pulled out from the engaging groove portion 630 of the groove 626, and the connection of the dolly 502 to the bed 10 is released. In this state, the operator holds the handle 568 and retracts the carriage 502 to disengage the pair of engaging members 620 from the cam 652. At this time, the roller 622 provided on the engagement member 620 is guided by the upwardly inclined surface 660 in the backward direction of the carriage 502 and rides over the cam 652. After the engaging member 620 is pulled out of the cover 470 and pulled out of the component supply device 18, the operator operates the handle 534 to rotate the lever 520 and lower the pallet support table 510. The four levers 520 are rotated at the same time to support the pallet with a feeder 326.

3), the handle 534 is operated to lower the pallet support table 510 to a position where the lower end of the cover 552 provided on the pallet support table 510 indicates a preset value of the scale 554.

After removing the dolly 502 from the parts supply device 18, the worker moves the dolly 502 to the work table 500 and connects the dolly 502 to the bed 10 in the same manner as the work table 50.
After connecting to 0, the pallet with a feeder 326 is transferred onto the workbench 500. After the feeder pallet 326 is placed on the workbench 500, the carriage 502 may be detached from the workbench 500, or the pallet 326 with a feeder may be left transferable and still transferable.

The pallet with a feeder 326 described above
Each operation for transfer between the component supply device 18 and the dolly 502 and a pallet 326 with a feeder described later.
Each operation for locating the vehicle from the dolly 502 to the moving table 134 is completed and detected by a sensor (not shown) as necessary, and the next operation is performed based on the completion. . For example, the parts supply table 1
20,122 move to the shelter area, stop at the shelter position,
The positioning (clamp) of the pallet with feeder 326 with respect to the moving base 134 is released, the engagement pin 666 is engaged and released by the engaging device 664, the pallet with feeder 326 is transferred from the carriage 502 to the moving base 134, and clamps are performed. It is detected and confirmed by the sensor.

In the first mode, the two component supply tables 120 and 122 in which the feeder 130 is similarly mounted are also provided.
When the electronic parts 140 are replaced based on the out-of-parts and the electronic table 140 is supplied by using the save table as the production table, in the parts supply table which is the save table from the production table, the feeders that are out of parts are The electronic component 140 is replenished by replacing 130, and if there is a connectable feeder capable of connecting the taped electronic component 142, the taped electronic component 142 is connected and the electronic component 140 is replenished. It
The connectable feeder is a new taped electronic component 1 in addition to the taped electronic component 142 which is currently supplying the electronic component 140.
It is a feeder that does not cause trouble even if 42 is connected, and there are no parts shortage, but there are few electronic parts 140 remaining,
Therefore, it is the feeder 130 to which the taped electronic component 142 can be connected. It is also a feeder that is likely to run out of parts in the near future. The determination of connectable feeder is
It may be performed for each of the plurality of feeders, and may be determined, for example, at a preset time or when a condition is satisfied, or may be determined each time one electronic component 140 is supplied.

The connectable feeder is a taped electronic component 14
It is determined in various modes depending on the difference in how the remaining amount of 2 is expressed. One is a length-dependent connectable feeder determination mode that is determined based on the actual length of the taped electronic components 142 remaining in the feeder 130, and one is the number of electronic components remaining in the feeder. It is a remaining part number-dependent connectable feeder determination mode determined based on the remaining number, and one is a remaining time-based connectable feeder determination mode determined based on the time when an electronic component can be supplied by the feeder. One of these modes is selected by the operator using the input device 724, and the connectable feeder is determined by any one of the modes. The determination of the connectable feeder is performed by the system computer 702 in this embodiment.

The length-dependent connectable feeder determination mode will be described. In this mode, the actual length, which is a kind of the actual remaining amount of the taped electronic components 142 remaining in the feeder 130, is the length that can be further wound around the reel 150 around which the new taped electronic components 142 are wound. In addition, the feeder 130 that is shorter than the wrappable length, which is a type of wrappable amount, is the connectable feeder.
In the present embodiment, the actual length of the taped electronic component 142 is acquired based on the number of remaining components, which is the number of electronic components 140 remaining in the feeder 130, and the electronic component holding pitch of the taped electronic component 142. To be done. It is obtained by multiplying the electronic component holding pitch by the number of remaining components.

The number of remaining components is, for example, from the number of electronic parts 140 at the time of detecting a connecting portion, which is the number of electronic components 140 held by the feeder 130 when the connecting portion of the taped electronic component 142 is detected by the connecting portion detecting device 292. It can be obtained by subtracting the number of electronic components 140 supplied after the detection of the connection portion. The number of remaining parts is calculated from the feeder 130 to the electronic parts 140.
Each time one is supplied, the electronic component 14 of the feeder 130 is supplied.
It may be obtained by decreasing the number of held 0s by 1 or by counting the number of supplied electronic components 140 and determining the connectable feeder from the number of connected parts detected or the initial total number of parts. It may be acquired by pulling.

The number of electronic parts held by the feeder 130 when the connection part of the taped electronic part 142 is detected is the number of electronic parts between the connection part detection position and the supply part and the new taped electronic part. This is the sum of the number of electronic components held by the component 142. Therefore, in the feeder 130, the connection portion of the tape-shaped electronic component 142 is connected to the connection portion detection device 2
If detected by 92, the detection information is provided from pallet computer 722 to system computer 702. As a result, in the system computer 702, the value of the counter that counts the number of remaining parts of the feeder 130 in which the connection part has been detected is the same as the number of electronic parts 140 located between the connection part detection position and the supply part. Electronic component 140 held by taped electronic component 142
Is reset to the sum of the numbers.

The number of electronic parts 140 between the connection part detection position and the supply part is obtained based on the distance between the connection part detection position and the supply part and the electronic part holding pitch of the taped electronic parts 142. . The distance between the connection detection position of the feeder 130 and the supply unit is known by design, and is supplied from the host computer 718 to the system computer 702. In addition, the number of electronic components 140 held by the new taped electronic component 142 and the electronic component holding pitch are obtained from the reel information acquired by reading the bar code provided on the reel 150.

The bar code on the reel 150 is read, for example, when the reel 150 is mounted on the feeder 130. When the reel 150 is mounted on the feeder 130 in a state where the feeder 130 is not attached to the pallet 132, bar codes provided on the reel 150 and the feeder 130 are read, and the reel information and the feeder information are associated with each other. Host computer 7
18 are stored. Further, when the feeder 130 is mounted on the pallet 132, the pallet 13 of the feeder 130
2 is input, the barcode of the feeder 130 is read, and the system computer 702 stores the attachment position of the feeder 130 and the feeder information (including the feeder identification code) in association with each other. And the host computer 718
The reel information and the feeder 130 information supplied from are stored, and are used for setting the number of electronic components 140 held by the feeder 130 and the like. The number of electronic components 140 held by the feeder 130,
The number of remaining parts in (1) is calculated for each feeder 130 in the system computer 702, and stored in association with the mounting position of the feeder 130 on the pallet 132. Also when counting the number of parts supplied to the feeder 130, the counting is performed for each feeder 130. When the feeder 130 is removed from the pallet 132, the number of remaining components is sent to and stored in the host computer 718 in association with the feeder identification code, and then the feeder 130 is mounted on the pallet 132 again to supply the electronic component 140. At this time, the number of remaining parts of the feeder 130 is sent from the host computer 718 to the system computer 702 and the number of remaining parts is counted. The host computer 718 and the system computer 702 jointly manage the number of remaining parts of the feeder 130.

The windable length is a length that can be additionally wound on the reel 150 on which the new tape-shaped electronic component 142 is wound. A new taped electronic component 142 is wound around the reel 150 with a margin left up to the outer peripheral surfaces of the pair of side wall portions 154. As shown in FIG. 5, the outer peripheral surface of the new taped electronic component 142 and the reel 1 are wound.
There is a gap between the outer peripheral surface of the tape 50 and the taped electronic component 142. This gap is a winding allowance corresponding to the amount of the taped electronic component 142 that can be additionally wound on the reel 150 on which the new taped electronic component 142 is wound, and the possible winding length is based on this winding allowance. It is determined.

The length that can be wound is the diameter R1 of the outer peripheral surface of the reel 150, the diameter R2 of the outer peripheral surface of the new tape-shaped electronic component 142 wound around the reel 150, and the thickness T of the tape-shaped electronic component 142 (see FIG. 7 (b)). These are obtained from the reel information obtained by reading the bar code provided on the reel 150, the wrappable length is calculated, and data identifying the feeder 130, for example, the position of attachment of the feeder 130 to the pallet 132 is associated with the system. It is stored in the computer 702. The rollable length may be calculated at the time of determining the connectable feeder, or the diameters R1, R2 and the thickness T are determined by the reel 150, and the rollable length is calculated in advance and stored as reel information. Alternatively, the reel 150 may be the feeder 13
Each time it is set to 0 and the diameters R1 and R2 and the thickness T are obtained, it may be calculated in the system computer 702 or the pallet computer 722,
Alternatively, it may be calculated or acquired when the feeder 130 holding the reel 150 is mounted on the pallet 132.

The larger the wrappable length, the more easily the taped electronic components 142 can be connected. That is, since the replenishment is performed early, it is easy to avoid the occurrence of the component shortage, but the new taped electronic component 142 is shortened accordingly, and the number of the replenished electronic components is reduced. Therefore, when the connectable feeder is determined by the length of the tape-shaped electronic component 142, the wrapable length is the maximum amount of the tape-shaped electronic component 142 that can be held by the reel 150 in the present embodiment. The maximum length of a certain tape holding device is set to 15% of the length of the taped electronic component 142 when the taped electronic component 142 is wound up to the full outer peripheral surface of the reel 150. The reel 150 to which the electronic component 140 is replenished by splicing is made so that a new taped electronic component 142 can be wound, leaving a gap in which the taped electronic component 142 having a length of 15% can be wound. ing. Therefore, the rollable length is the diameter R1 of the outer peripheral surface of the reel 150, the thickness T of the taped electronic component 142, the diameter of the boss portion 152, and the rollable length of the reel 150 that can be held by the reel 150. It may be calculated based on the ratio of the electronic component 142 to the maximum length. The diameter of the boss portion 152 is stored as reel information, for example.

The actual length of the taped electronic parts 142 remaining in the feeder 130 can be calculated if the number of remaining parts is obtained, and may be calculated when the number of remaining parts is obtained, or the connectable feeder May be calculated when necessary, such as when deciding, or when deciding the connection priority.

The actual length of the taped electronic component 142 obtained as described above is compared with the wrappable length,
If the actual length of the tape-shaped electronic component 142 is equal to or larger than the wrappable length, the feeder including the tape-shaped electronic component 142 is not a connectable feeder. On the other hand, if the actual length of the taped electronic component 142 is shorter than the wrappable length, the feeder having the taped electronic component 142 is a connectable feeder, and the feeder 13
The data specifying 0 is stored in the system computer 702 in association with, for example, the attachment position.

Of the taped electronic parts 142, the taped electronic parts in the portion between the supply part and the tape pull-out part of the reel 150 are not wound around the reel 150.
Therefore, if the actual length of the tape-shaped electronic component 142 is shorter than the wrappable length, there is a margin for drawing out from the reel, and when the tape-shaped electronic component 142 is wound around the new tape-shaped electronic component 142, the reel 15
It is avoided to run out of zero. Of course, the remaining length may be a length obtained by subtracting the length that cannot be wound, or the length that can be wound may be increased by the length.

The connectable feeder is determined by the feeder 13
0 may be performed every time one electronic component 140 is supplied, or at a preset time, for example, when a component is out or the number of supplied electronic components 140 exceeds the set number and the set rate. It may be performed in some cases. The set rate is, for example, the electronic component 140 held by the feeder 130 when the taped electronic component 142 is new.
, The number of electronic components 140 supplied to one printed wiring board 30 supplied by the feeder 130, and the like. When the connectable feeder is determined each time one electronic component 140 is supplied, the feeder 130 set at the time of detecting the connection portion is supplied each time one electronic component 140 is supplied.
The number of electronic components 140 held by is reduced by one, and the number of remaining components is acquired. When the number of connectable feeders is determined at a preset time, the number of remaining components may be obtained by subtracting each time one electronic component 140 is supplied. It may be obtained by subtracting from the number of parts when the connection portion is detected. This is the same regardless of whether the connectable feeder is determined by the remaining part number-based connectable feeder determination mode or the remaining time-based connectable feeder determination mode.

The number of remaining parts in the feeder 130 is the same as that of the feeder 13 regardless of whether or not the connectable feeder is determined.
The count is 0 while the electronic component 140 is being supplied. Therefore, as will be described later, when a plurality of connectable feeders are determined, their connection priority is determined. For example, when the connectable feeder is determined every time one electronic component 140 is supplied. Even if the feeder 130 is once determined to be a connectable feeder, the number of remaining components is acquired every time one electronic component 140 is taken out from the feeder 130 thereafter. At the same time, the difference between the actual length of the taped electronic component 142 and the wrappable length may be calculated, or may be calculated when the connection priority order is determined. This is the same regardless of whether the connectable feeder is determined by the remaining part number-based connectable feeder determination mode or the remaining time-based connectable feeder determination mode.

Connectable feeder 13 based on the number of remaining parts
The determination of 0 will be described. As described above, the number of remaining components is one from the number of electronic components 140 held by the feeder 130 set at the time of detecting the connection portion of the tape-shaped electronic component 142, one by one, or the connectable feeder. Is determined by subtracting the number of supplied parts counted up to that time from the number of parts held by the feeder 130 at the start of counting. Then, the number of remaining parts is compared with the set number of parts, and if the number is less than the set number of parts, the feeder 130 is determined to be connectable.

The set number of parts may be any number that allows the feeder 130 to determine that a new taped electronic part 142 can be connected.
In addition to the number corresponding to the length that can be wound around the reel 150 without protruding from the reel 150, the occurrence of component shortage can be avoided and the holding amount of the taped electronic component 142 by the reel 150 can be excessively reduced. Is set to no number. Further, in this embodiment, the number is set to be larger than the number of electronic components 140 located between the tape end detection position and the supply unit. The number of set components may be changed or may be the same depending on the type of the taped electronic component 142. When changing depending on the type of the taped electronic component 142, for example, the larger the number of the electronic components 140 supplied to one printed wiring board 30, the larger the number is set, or the electronic component held by the taped electronic component 142 in a new state is set. The smaller the number of parts 140 is, the larger the number is set.

The set number of parts is set by the operator in this embodiment, and is input to the system computer 702 using the input device 724. For example, the operator inputs the set number of parts for each of the plurality of feeders 130 mounted on the pallet 132 when setting the component mounting mode and setting the connectable feeder determination mode. At this time, the mounting position of the feeder 130 on the pallet 132 is also input, and the number of set components is stored in association with the mounting position on the pallet 132, which is information for identifying the feeder 130. The number of set components is 142
It may be set in advance for each type, for example, supplied from the host computer 718, or may be stored as reel information. When determining the connectable feeder 130 based on the number of remaining components, the number of electronic components 140 in the portion between the supply unit and the tape pull-out unit of the reel 150 may be taken into consideration. For example, the number of set components is set assuming that there is no electronic component 140 for that amount.

Connectable Feeder 130 Based on Remaining Time
Explain the decision. The remaining time is the time during which the electronic component 140 can be supplied without causing the component supply table to run out of components, and the individual feeders 130 can supply the electronic component 14 according to the number of the electronic components 140 remaining in the feeder 130.
This is the time required to mount all the planned electronic components 140 on all of at least one printed wiring board 30 that can supply 0. The feeder 1 is capable of supplying the electronic component 140.
30 has at least one electronic component 140 sufficient to be mounted on the printed wiring board 30, and the remaining time corresponds to the number of printed wiring boards 30. Therefore, the remaining time may be determined by the number of printed wiring boards 30 or the time.

The remaining number is obtained by dividing the number of remaining components in the feeder 130 by the number of electronic components 140 taken out for performing the mounting work on one printed wiring board 30 and rounding down the fraction. The remaining time is obtained by the obtained integer, and the remaining time is obtained by multiplying the time required for the mounting work of all the electronic components 140 scheduled for one printed wiring board 30 by the remaining number. Then, the remaining number of sheets or the feeder 130 whose remaining time is shorter than the set number of sheets or the set time is determined as the connectable feeder.

The set number of sheets and the set time are determined by the feeder 13
0 may be the number and time at which it can be determined that a new taped electronic component 142 can be connected.
The number of tapes and the time for which the taped electronic parts 142 remaining on the tape 30 can be wound on the new taped electronic parts 142 without protruding from the reel 150, and of course the occurrence of parts shortage is avoided, and The number and time of holding the taped electronic components 142 by the reel 150 are set so as not to be excessively reduced. The set number of sheets and the set time may be changed or may be the same depending on the type of the taped electronic component 142, like the set number of components.

The set number of sheets and the set time are set by the operator in this embodiment, and the system computer 702 uses the input device 724 similarly to the set number of parts.
And is stored in association with the feeder 130.
Similar to the set number of parts, for example, a taped electronic part 1
It may be preset according to the type of 42. In addition,
Also when determining the connectable feeder 130 based on the remaining time, the number of electronic components 140 in the portion between the supply unit and the tape pull-out unit of the reel 150 may be taken into consideration. For example, the set number of sheets and the set time are set assuming that there is no electronic component 140 for that amount.

Regardless of which mode determines the connectable feeder, if the supply of the electronic component 140 progresses and a component shortage occurs and is detected, the component supply table is replaced. When one feeder 130 supplies a plurality of electronic components 140, even if a component shortage is detected during the supply, the tables are replaced after the feeder 130 finishes supplying the set number of electronic components. The parts supply table may be changed during the supply.

When there are a plurality of connectable feeders, the connection priority is determined. In the present embodiment, the connection priority is set to the system computer 7 when a component shortage is detected.
02, and the determined priority is supplied to the pallet computer 722 together with the data indicating the connectable feeder and the data indicating the out-of-part feeder. Connectable feeder is taped electronic component 142
When determined based on the actual length of the taped electronic component 142 that can be wound on the new reel 150, the actual length of the taped electronic component 142 currently set in the feeder 130 is determined. The larger the difference obtained by subtracting the length, the higher the priority of connection. When the connectable feeder is determined at the time of out-of-component occurrence, the connection priority is determined together with the determination.

When the connectable feeder is determined based on the number of remaining parts, the connection priority is determined based on the number of remaining parts, and the feeder having the smaller number of remaining parts has the higher priority. When the connectable feeder is determined based on the remaining time, the connection priority is determined based on the remaining time, and the feeder having a shorter remaining time has a higher priority. When the remaining number is used as the remaining time, the smaller the remaining number, the higher the connection priority. The pallet computer 722 may be made to determine the connectable feeder and the connection priority by supplying information from the system computer 702.

If there is only a part-out feeder and there is no connectable feeder, the electronic part 140 of the part-out feeder will be used.
Only the exchange with the feeder 130 having At this time, the blinking of the lamp 204 provided on the feeder 130 and the display on the display screen 734 cause the feeder 1

The type of 0 is instructed to the operator. A plurality of feeders 130 are mounted on the pallet 132 in a state where the respective supply units are aligned in a straight line. In the feeder 130 in which the parts are cut off, the end of the taped electronic component 142 is the reel 150.
Since the tape has come off to the tape end detection position, it is difficult to perform the tape connection work described later with the feeder 130 still mounted on the pallet 132, and the parts are replenished by replacing the feeder 130. Alternatively, if the reel 150 is removed from the feeder 130 in which the lamp 204 is blinking and the reel 150 is empty, it is known that the component is out of the feeder.

When replacing the feeder 130, if the new reel 150 is already set in the feeder 130, the barcode of the feeder 130 is read by the barcode reader 7.
42 and reads the mounting position of the feeder 130 by the input device 740.
Enter in 22. These data are sent from the pallet computer 722 to the system computer 702 when the pallet with feeder 326 is returned to the moving table 134, and the reel information, the feeder information and the mounting position of the electronic component 140 stored in the system computer 702. Based on the information and the like, it is confirmed whether or not the type of the electronic component 140 of the reel 150 held by the feeder 130 is the electronic component 140 to be supplied at the mounting position. Further, the number of remaining parts of the feeder 130 is set to the initial number, that is, the number of taped electronic parts 142 in a new state. If the feeder 130 is already used to supply the electronic component 140, the number of remaining components of the feeder 130 is calculated from the host computer 718 to the system computer 702 based on the feeder information.
Supplied and set. Further, the data indicating that the component is out of stock is erased. The reel 15
If 0 is not set in the feeder 130, the reel 150 is set in the feeder 130 and replaced with the component out feeder. In this case, the reel 150 and the feeder 1
The barcodes provided on the respective 30 are read to confirm the types of parts, and the reel information and the feeder information obtained by the reading are later sent from the system computer 702 to the host computer 718 and stored therein.

If there is a connectable feeder in the component supply table, the taped electronic components 142 are connected to the connectable feeder in accordance with the connection priority after the component out feeder is replaced. The connectable feeder and the connection priority are displayed on the display screen 734. The display screen 734 displays data regarding the connectable feeders, for example, the types of electronic components 140 supplied by the feeders, the mounting positions of the feeders on the pallet 132, and the like. Further, as described above, the pallet 326 with the feeder is used for the carriage 5

The connection to 0 is released. If the dolly 502 may remain connected to the bed 10, the connection may not be released.

When the taped electronic component 142 is connected, the bar code on the reel 150 around which the new taped electronic component 142 is wound is read by the bar code reader 742. The reading of the bar code may be performed before or after the connecting work. At this time, the attachment position of the feeder 130 to the pallet 132 is set to the input device 74.
0 is input to the pallet computer 722, and the mounting position and the read reel information are associated with each other and stored in the pallet computer 722. These pieces of information are transferred from the pallet computer 722 to the system computer 702 after the transfer of the pallet 326 with a feeder to the moving table 134, and whether the reel 150 set on the feeder 130 is suitable, that is, the connected taped electronic components 142. Whether or not the type is correct (whether or not the type should be supplied at the mounting position of the feeder 130) is determined.

The suitability of the reel 150 is determined by the system computer 702 in this embodiment.
In the system computer 720, as described above, the type and number of the printed wiring boards 30 on which the electronic components 140 are mounted, the mounting position of the electronic components 140 on the printed wiring board 30, the type of the electronic components 140 to be mounted, and the feeder. 1
30 mounting positions on the pallet 132 and the feeder 13
Various data such as data associating with the type of electronic component supplied by 0 are stored, and the mounting position of the feeder 130 input when the taped electronic component 142 is connected and the read reel information are stored in the system computer. Information stored in 702, namely feeder 130
Is compared with the data associating the mounting position with the type of the electronic component 140 to be supplied, and it is determined whether or not the connected taped electronic component 142 is to be connected. If they do not match, it is considered that the wrong type of taped electronic component 142 has been connected, and the occurrence of abnormality is notified and displayed using the alarm 732 and the display screen 734. Thereby, for example, the taped electronic component 142 is reconnected. If so, a message to that effect is displayed. It is preferable that the work of closing the cover and the input of the movement approval information are performed after the suitability of the reel 150 is determined.

The suitability of the reel 150 may be determined by the pallet computer 722.
It may be performed in the workplace. Information that associates the mounting position of the feeder 130 set on the pallet 132 with the type of the electronic component 140 supplied at each mounting position is previously stored in the system computer 70.
2 to the pallet computer 722 for storage, and the worker inputs the mounting position and reads the bar code provided on the new reel 150 at the time of connecting the taped electronic components 142, and determines the suitability of the reel 150. Is done.

Data specifying the feeder 130 to which the electronic component 140 is replenished by connecting the taped electronic component 142, for example, attachment position data of the feeder 130 to the pallet 132, is sent from the pallet computer 722 to the system computer 702. For the feeder 130 for which the tape connection has been completed, the data that indicates that it is a connectable feeder is erased and the data that indicates that the tape connection has been performed is stored. Therefore, after the connection, the number of remaining components in the feeder 130 is continuously counted before the connection until the tape connection portion is detected, but the number of remaining components is small and the feeder is not a connectable feeder. Then, if the connection portion is detected, the number of the electronic components 140 held by the feeder 130 is reset, and the data indicating that the tape connection is completed is erased to determine whether the feeder is a connectable feeder. And the determination of connectable feeders is made. It should be noted that before the detection of the connection portion, the printed wiring board 30
When the mounting of the electronic component 140 on the electronic component 140 is completed, the number of remaining components remains the same as before the connection and remains small, but data indicating that the connection has been made is stored, and the feeder 130 and the remaining component number are stored. Since they are stored in association with each other, when the feeder 130 is used to supply the electronic component 140 next time, the feeder 130 does not make it a connectable feeder, and the data indicating that the connection is made by detecting the connection portion. Is erased, the number of remaining components is reset, and the number of components held by the connected tape-shaped electronic component 142 is incorporated into the number of remaining components.

The number of remaining electronic parts is 1
It may be reset when it is detected that the connection portion of 42 reaches the supply portion. After the detection of the connection portion, the number of electronic components 140 between the connection portion detection position and the supply portion
If is supplied, it is determined that the connection portion has reached the supply portion, and the number of remaining components is reset to the number of electronic components 140 held in the taped electronic component 142 in a new state.

The time for the operator to connect the taped electronic components 142 is not limited. If the component supply table supplying the electronic component 140 in the component supply region is out of components, the component supply table must be replaced and the component supply table that is being saved in the save region must be moved to the component supply region. Is. Therefore, when it is necessary for the component supply device 18 to move the retracted moving table 134 from the retracted area while the worker is performing the connecting operation of the tape-shaped electronic component 142, that fact is reported. The operator is notified by the notification device 732.

In the present embodiment, the notification is before the occurrence of parts exhaustion, and if the connection work is not completed at the time of notification, the connection work currently being performed by the worker is ended and the parts supply table is saved in the save area. Is issued at a time when sufficient time is obtained to make the movable state from the to the component supply area. Before parts run out, pallet with feeder 32
6 is transported from the workbench 500 to the electronic component mounting system 12 by the carriage 502, set on the moving stand 134, the suitability of the reel 150 is determined, the open / close cover is closed, and movement approval information is sufficient. Emitted when time is available. Advance notification is made.

Therefore, for example, in the system computer 702, the remaining time is calculated for the feeder 130 determined as the connectable feeder of the component supply table during the component supply, and the connectable feeder whose remaining time becomes equal to or less than the set time is found. If it happens, a notification will be given. The remaining time is obtained in the same manner as when the connectable feeder is determined based on the remaining time. Here, the number of remaining components is divided by the number of electronic components 140 supplied to one printed wiring board of the feeder to obtain a fractional number. The integer obtained by rounding down is 1
It is obtained by multiplying the time required for mounting electronic components on a single printed wiring board and compared with the set time. At this time, it is desirable to consider the number of electronic components 140 located between the supply unit and the tape end detection device 290. For example, the number of electronic components 140 is excluded from the number of remaining components to determine the number of printed wiring boards, and the remaining time is determined. If the connection work is not completed at the time of notification for the set time, the worker finishes the connection work as described above and returns the pallet with a feeder 326 to the moving base 134 to make the component supply table movable. Is enough time. Remaining time is calculated by the connectable feeder as electronic component 1
This is performed every time one 40 is supplied, and if there are a plurality of connectable feeders, all 40 are performed. The notification may be performed when one connectable feeder whose remaining time is equal to or less than the set time is generated, or when a plurality of connectable feeders are generated, and each of the connectable feeders is notified. It may be performed when the average value of the remaining time becomes equal to or less than the set time.

In this way, the worker can make the tape-shaped electronic component 1
In order to inform the operator that it is necessary to move the movable base 134 from the retracted area while connecting 42, in order to calculate the remaining time until the occurrence of parts shortage, in the first mode, , The number of remaining components is obtained each time one electronic component 140 is supplied to each of the plurality of feeders 130, and the connectable feeders are determined.
When a connectable feeder is generated, the remaining time is calculated every time one electronic component 140 is supplied to the connectable feeder, and the remaining time is compared with the set time. Or, for example,
If the number of supplied electronic components in the feeder exceeds the set rate or the number of remaining parts becomes less than the set number, the connectable feeder is determined every time one electronic component 140 is supplied, and after the determination, The remaining time is calculated and compared with the set time.

If the worker has not completed the connecting work at the time of notifying the movement of the retracted parts supply table to the parts supply area, the worker finishes the connecting work in progress and then loads the pallet with a feeder 326. The work table 500 is transferred to the carriage 502, the carriage 502 is moved to the electronic component mounting system 12, the pallet with a feeder 326 is set on the moving stand 134, and the opening / closing cover 472 or 474 is closed. At least with regard to the part-out feeder, the supply of parts is completed by replacing the feeder.

Then, the operator uses the input device 724 to input the movement approval information into the system computer 702. At this time, even if the taped electronic components 142 have not been connected to all the connectable feeders 130, the connection work will be completed at the time of notification. After the movement approval information is input, when the parts run out in the operation table, the save table is moved to the parts supply area. If a component shortage has already occurred at the time of input, the save table is immediately moved to the component supply area to supply the electronic component 140. Information about the feeder 130, which has been connected to the tape-shaped electronic component 142, is supplied from the pallet computer 722 to the system computer 702.
Therefore, when the connection work is completed on the way, the taped electronic component 14 is set in the system computer 702.
The data indicating that the feeder 130 is connectable is deleted only for the feeder 130 to which the second connection is made.

If it is not informed that the parts supply table needs to be replaced before the worker finishes the connecting work, the worker can connect the taped electronic parts 142 to all the connectable feeders 130. . Then, after the work is completed, the pallet 132 is returned to the moving table 132, the movement approval information is input, and if the parts run out in the operation table, the evacuation table is immediately moved to the parts supply area and the electronic table is displayed. The component 140 is supplied.

As described above, in the first mode, when the component supply table runs out of components, the electronic component 140 is not only replenished to the component out feeder, but if there is a connectable feeder, the connectable feeder is also taped. By supplying the electronic component 140 by connecting the electronic component 142, it becomes difficult for the component supply table to run out of components, and the number of replacements of the component supply table can be reduced. The component supply table in which the taped electronic components 142 have been replenished is actually the electronic components 14
2 is moved to the component supply area instead of the component supply table that supplies 2, and the electronic component 140 is supplied. Then, the new taped electronic component 142 can supply the electronic component 140, and the electronic component 140 can be supplied without causing the component to run out. Therefore, it is satisfactorily avoided that the first and second component supply tables 120 and 122 are frequently out of components and the electronic component mounting system 12 stops operating, and the mounting efficiency and operating rate are improved.

Replenishment of electronic components when the electronic components are mounted in the second mode will be described. In the second mode of the present embodiment, one of the first and second component supply tables is normally in the component supply area to supply electronic components, and the other is retracted to the save area. Shortly before the end of the supply by the table, the other component supply table is moved to the component supply area and is moved integrally with the one component supply table, that is, in the same direction and at the same speed. Therefore, there is a period in which the two parts supply tables are both stationary and dormant in the save area.

In the case of the second mode, the component supply table is saved in the save area and put in the idle state even if no component shortage occurs, and the connectable feeder 130 is placed in the idle component supply table. For example, taped electronic components 1
42 connections can be made. Connectable feeder 13
The determination of 0, the determination of the connection priority order, etc. are performed in the same manner as in the first mode. The connectable feeder may be determined at a preset time, for example, when the number of supplied electronic components 140 exceeds the set number or set rate when the table is replaced, and one electronic component 140 is supplied. It may be determined for each. The connectable feeders and the connection priorities are displayed by, for example, blinking and lighting of the display screen 734, the lamp 204, etc. If there is a connectable feeder, the worker performs the connection work from the connection priority higher. If this connection work can be performed in the same manner as in the first mode, this may be done, but since it is usually impossible or inappropriate, the pallet 132 can be connected without removing it from the moving base 134. Work is done.

If the first component supply table 120 supplies the electronic component 140 first, the first component supply table 1
20 is an electronic component 1 according to the first component supply table 120
The supply of the electronic parts 140 is stopped until the supply of the electronic parts 140 to the next printed wiring board 30 is started, and the second parts supply table 122 starts supplying the electronic parts 140 by itself and then supplies the first parts. Electronic component 1 by table 120
Shortly before the end of the supply of 40, and until the second component supply table 122 starts moving to the component supply area,
Pause.

However, the supply time of electronic parts by each of the first and second part supply tables 120 and 122 is usually extremely short, and the rest time of each table 120 and 122 is very short. Therefore, in the present embodiment, Taped electronic parts 1 when the number of connectable feeders exceeds the set number
42 is connected, and the electronic component 140 by the component supply table in the component supply area is connected during the connection work.
Even when the table replacement is completed and the table replacement is completed, the supply of the electronic components 140 is interrupted and the printed wiring board 30 is supplied until the taped electronic components 142 are completely connected for the set number of connectable feeders. The mounting of the electronic component 140 is interrupted. Therefore, the set number is set so that the supply interruption time does not become too long. When the connectable feeder is generated, the feeder is sequentially displayed on the display screen 734, and accordingly, the worker prepares the reel 150 holding the new taped electronic component 142 to be connected near the component supply device 18 and waits for the connection. . Then, when the number of connectable feeders is equal to or more than the set number when the component supply table finishes supplying the electronic component 140 and saves the electronic component 140, the worker connects the taped electronic component 142. The feeder 1 with the open / close cover opened and the lamp 204 blinking
The taped electronic components 142 are connected from 30. The connection of the tape-shaped electronic component 142 is performed in the same manner as in the case of working, and is performed using the auxiliary reel holder 770. In the second mode, there is no notification that the component supply table during the connecting operation of the tape-shaped electronic component 142 is returned from the save area to the component supply area. If the number of connectable feeders is larger than the set number, the taped electronic components 142 are connected to the set number of connectable feeders having a high connection priority. After the taped electronic components 142 for all the set number of connectable feeders are connected, the open / close cover is closed, and the movement approval information is input.
The connected component supply table is moved to the component supply area to supply the electronic component 140. If there is at least one connectable feeder on the save table, connection work may be performed.

As described above, the connectable feeder 130 of the component supply table which is not in operation is taped electronic component 142.
If the connection is made, it is difficult for the parts to run out, but the parts may still run out. For example, if a component shortage occurs in one of the feeders 130 during the supply of the electronic component 140 by the first component supply table 120, the mounting of the electronic component 140 on the printed wiring board 30 is interrupted and the first component supply is performed. Feeder 130 of table 120
The electronic component 140 can be replenished. At this time, if there is a connectable feeder 130, the electronic component 140 may be replenished for the connectable feeder 130. In addition, the feeder 13 of the second component supply table 122
Also for 0, if there is a connectable feeder 130, the taped electronic component 142 may be connected in parallel with the work of connecting the taped electronic component 142 to the feeder 130 of the first component supply table 120. The same applies when the second component supply table 122 runs out of components.

When the first component supply table 120 runs out of components, the supply of the electronic component 140 by the first component supply table 120 is interrupted and the second component supply table 12
The mounting based on the supply of the electronic component 140 by 2 may be performed first, and the taped electronic component 140 may be connected to the first component supply table 120 during that period. Electronic component 140 based on the second component supply table 122
After the supply of the electronic components 140 is completed, the supply of the electronic components 140 by the first component supply table 120, which has been replenished with the electronic components 140, is performed. The same is true when the second component supply table 122 runs out of components.

If the second component supply table 122 can supply the electronic component 140 instead of the first component supply table 120, that is, the first component supply table 1
If the electronic component 140 of the same kind as the electronic component 140 supplied by 20 is included, when the first component supply table 120 runs out of components, the second component supply table 122 is moved to the component supply area. Then, the electronic component 140 may be supplied instead of the first component supply table 120, and the electronic component 140 may be mounted. The alternative supply by the second component supply table 122 may be performed after the supply of the other electronic components 140 by the first component supply table 120 is completed, or may be performed at the time when the parts are out of stock. . The same applies when the second component supply table 122 runs out of components.

Alternatively, the mounting of the electronic component 140 on the printed wiring board 30 is stopped and the printed wiring board 30 is temporarily stopped.
To the printed wiring board carry-out device, the next printed wiring board 30 is carried into the printed wiring board holding device 14, and the electronic component 14 is supplied by the second component supply table 122.
You may make it mount 0. In this case, the previous printed wiring board 30 is carried out, the next printed wiring board 30 is carried in, and the electronic component 14 is set by the second component supply table 122.
During the supply of 0, the taped electronic components 142 are connected to the first component supply table 120. The printed wiring board 30 in which the mounting of the electronic component 140 has been stopped and the printed wiring board 30 carried in next are both not mounted, and the taped electronic component 142 is connected to the first component supply table 120. After the completion, the electronic component 140 is returned to the wiring board holding device 14 to supply the electronic component 140 to the first component supply table 120, and the mounting of the electronic component 140 on the printed wiring board 30 is completed. When the first component supply table 120 runs out of components, after the mounting of the electronic component 140 by the supply of the second component supply table 122 is completed, the printed wiring board 30 is once carried out, and then the first component supply table is used. 12
The mounting of the electronic component 140 by the supply of 0 may be completed, the printed wiring board 30 is once carried out when the first component supply table 120 runs out of components, and then the first and second component supply tables 120 The mounting of the electronic component 140 may be completed by supplying 120 and 122. The mounting may be completed first for either the printed wiring board 30 that has been carried out first or the printed wiring board 30 that has been carried out next. Electronic component taped to the first component supply table 14
The number of the printed wiring boards 30 that are carried in during the connection of 2 and on which the electronic components 140 supplied by the second component supply table 122 are mounted is not limited to one and may be two or more. The same applies when the second component supply table 122 runs out of components.

Further, when the electronic component 140 is supplied from the first component supply table 120 and the taped electronic component 142 is connected to the connectable feeder in the second component supply table 122, the first component is supplied. When the supply of the electronic component 140 by the supply table 120 is completed, the second component supply table 122 is completed even if the supply is completed.
If the component does not move to the component supply area, the printed wiring board 30 may be once carried out, the next printed wiring board 30 may be carried in, and the electronic component 140 may be supplied to the first component supply table 120. In this case, the printed wiring board 30 that has been carried out first and the printed wiring board 3 that has been carried in next are
After the connection of the taped electronic component 142 in the second component supply table 122 is completed, 0 is returned and the electronic component 140 supplied by the second component supply table 122 is mounted. The electronic components 140 may be attached to the two incomplete printed wiring boards 30 in any order. The first component supply table 120 is the second component supply table 122.
Alternatively, the electronic component 140 may be supplied if it can be supplied. The end of supply of the electronic component by the first component supply table 120 may be notified at the end of the supply or before the end. Further, in the first component supply table 120, taped electronic components 142
If the connection is made and the supply is not in time, the second component supply table 122 may be made to supply the electronic component 140 first, and if possible, the second component supply table 122.
Alternatively, the electronic component 140 may be supplied as an alternative.

Further, since the down time of the component supply table is short, the taped electronic component 142 may be replaced with the feeder to replenish the electronic component 140. With respect to the removed feeder, the taped electronic components 142 are connected immediately or as needed.

As described above, the electronic component 1 is operated by the second mode.
When the 40 is mounted on the printed wiring board 30, the taped electronic components 142 are connected to the connectable feeder to avoid the occurrence of component shortage in the two component supply tables 120 and 122, and the electronic component mounting system 12 The operation is prevented from stopping. Further, even if parts are cut off, the number of times can be small, and the stop time of the electronic parts mounting system 12 can be short. Even if the connection of the tape-shaped electronic component 142 is not made in time for the replacement of the table and the supply and mounting are interrupted, the occurrence of component shortage is reduced, and the electronic component mounting system 1 is therefore reduced.
2, the stop time can be shortened and the mounting efficiency can be improved.

Supply of the electronic component 140 in the third mode will be described. In the case of supplying the electronic component 140 in the third mode, the electronic component 140 is supplied by one of the first and second component supply tables 120 and 122. Therefore, the feeder 13 of the component supply table which is not in operation in the shelter area
0, the electronic parts 140 can be replenished, and the connectable feeder 130 can be taped electronic parts 142.
Connection can be made.

First and second component supply tables 120, 12
When the printed wiring boards 30 to which the electronic components 140 are supplied are different from each other, but the types of the printed wiring boards 30 to which the electronic components 140 are supplied by the respective tables 120 and 122 are not different, the electronic components from one component supply table are used. During the supply of the component 140, the electronic component 140 is replenished for the connectable feeder of the component supply table which is not in operation. The pallet with a feeder 326 is detached from the moving table 134 and mounted on the work table 500, and the tape-shaped electronic component 142 is attached.
The connection is made. Determining connectable feeders,
The determination of the connection priority and the connection work of the taped electronic component 142 are performed in the same manner as when the electronic component 140 is mounted in the first mode. The connectable feeder may be determined, for example, at a preset time, for example, when the supply of electronic components by the component supply table is completed, and is performed when the number of supplied electronic components 140 exceeds the set number and the set rate. Alternatively, it may be determined each time one electronic component 140 is supplied. Further, the operator is informed that it is necessary to move the movable base 134 from the retracted area before the set time has elapsed from the end of the supply by the one component supply table. Then, the connecting work of the tape-shaped electronic component 142 is completed, the pallet with a feeder 326 is returned to the moving table 134, and the movement approval information is input, so that the component supply table can be moved to the component supply area. It

If there are many types of printed wiring boards 30 and the types of printed wiring boards 30 on which the tables 120 and 122 supply the electronic components 140 are changed, if the component supply table finishes supplying the electronic components 140, Setup change is performed. The setup change is performed, for example, by replacing the feeder 130 with the pallet 132. In advance, the feeder 130 is mounted on the pallet 132 according to the type of the printed wiring board 30, and when the type of the printed wiring board 30 is changed, the pallet with a feeder 326 currently attached to the moving table 134 is moved to the moving table 134. Remove from
Next, the pallet 132 on which the feeder 130 that supplies the electronic component 140 is mounted is mounted on the moving table 134. The pallet 326 with a feeder can be attached and detached using the carriage 502.

At the time of setup change, the pallet with a feeder 326 removed from the moving table 134 may be kept waiting for the next supply, or the feeder 130 may be removed from the pallet 132. In any case, it is desirable to connect the taped electronic component 142 to the connectable feeder. In the former case, the taped electronic component 142 may be connected during standby, or may be connected to the work table 500 or the moving table 134 when the feeder pallet 326 is next used for supplying the electronic component 140. Good. In the latter case,
The taped electronic components 142 may be connected when the feeder 130 is removed from the pallet 132, or may be attached to the pallet 132 for use in supplying the electronic components 140 next.

When the feeder 130 is still mounted on the pallet 132, the data regarding the feeder 130 and the reel 150 is stored in the system computer. It may be stored in the palette computer 722 and the host computer 718. If taped electronic components are connected during standby, the feeder 13
0, the taped electronic component 142 was connected, the position of the connected feeder 130 to the pallet 132, the reel information obtained by reading the bar code of the reel 150, the feeder 130 and the feeder 1.
Data relating to the reels 150 held by 30 is stored in the pallet computer 722. When the feeder 130 is scheduled to be removed from the pallet 132 due to a setup change or the like, data regarding the feeder 130 and the reel 150 held by the feeder 130 is transferred from the system computer 702 to the host computer 718.
Sent to and stored for later use. It may be stored in the host computer 718 by input by the operator. Thereby, when the feeder 130 in the idle state is used for supplying the electronic component 140 next time, the data regarding the feeder 130 and the reel 150 held by the feeder 130 is supplied from the host computer 718 to the system computer 702, and the number of remaining components remains. It is used for management. Used feeder 13
0 is specified by the identification code obtained by reading the barcode. The information about the feeder and reel is the feeder information obtained by reading the barcode,
In addition to the reel information, for example, in the case of a connectable feeder, information indicating that it is a connectable feeder, data acquired to determine the connectable feeder (actual length of taped electronic component, remaining time, remaining The number of parts, the number of set parts, the set time, etc. are included, and if the feeder is not a connectable feeder, the number of parts supplied, the number of remaining parts, etc. are included. Further, when the taped electronic components 142 are connected after the feeder 130 is removed from the pallet 132, data to that effect is input to the host computer 718 and stored in association with the feeder information. The storage of these data in the host computer 718 is similarly performed when the setup is changed when the parts are supplied in the first and second modes and the feeder is scheduled to be removed from the pallet. . Also, when the feeder is removed from the pallet for a reason other than the setup change, the feeder is similarly stored. The pallet may also be provided with an identification code for individually identifying it, for example, a bar code may be provided and stored. For example, if the feeders are kept attached to the pallet and you wait, you can save the data about the feeders attached to the pallet, and the next time you use those feeders to supply parts, You can see the feeder that supplies the parts.

Whichever mode the third mode is performed in, the feeder 13 of the component supply table being supplied is supplied.
If the component runs out at 0, the mounting of the electronic component 140 is interrupted and the taped electronic component 142 is connected.
For this connection work, the pallet with feeder 326 is moved to the moving table 1.
It is performed in a state where it is attached to 34. If there is a feeder 130 that holds an electronic component 140 of the same type as the electronic component 140 that has run out of components, the feeder 130 of the resting component supply table can supply that electronic component 140 to the feeder 130. May be done. In the alternative supply performed by the component supply table during suspension, all the electronic components 140 other than the electronic component 140 in which the component has run out are mounted on the printed wiring board 30 by the supply of the electronic component 140 by the component supply table being supplied. It may be carried out after the above, or may be carried out at the time when the parts are out.

Thus, in the third mode, by splicing the taped electronic component 142 with respect to the connectable feeder and supplying the electronic component 140, it is possible to avoid the occurrence of component shortage, or even if it occurs, the number of times is reduced. This can be reduced, and the operation stop time of the electronic component mounting system 12 can be reduced.

When the electronic component 140 is mounted by any of the first to third modes, the taped electronic component 142 is peeled off from the carrier tape 144 if necessary. The cover tape 146 is processed. In the illustrated example, the storage case 2
70 is made of a transparent synthetic resin, and the operator uses the storage case 2
When a predetermined amount of the cover tape 146 is accommodated in the housing case 270 as viewed from the outside, the housing case 270
The cover tape 146 is taken out from. The predetermined amount is, for example, a large amount of the cover tape 146 accommodated, and the feeder 13
0, when a new taped electronic component 142 is set and the electronic component 140 is supplied, the housing case 270
The cover tape 146 in the inside becomes excessive, and the storage case 27
The amount is slightly smaller than the amount that may hinder the feeding of the cover tape 146 into 0. The predetermined amount is indicated by marking the housing case 270, for example.

If the amount of the cover tape 146 accommodated exceeds a predetermined amount, or if the cover tape 1 has an amount close to the predetermined amount.
If 46 is stored, the operator opens the lid 276,
The cover tape 146 is taken out and cut at the base end. The base end is the drive gear 2 of the cover tape 146.
The portion that is sandwiched between 44 and the driven gear 246 and protrudes into the housing case 270 is a portion that is close to the drive gear 244 and the driven gear 246. After taking out, the lid 27
Close 6 The operation of taking out the cover tape 146 may be performed by rotating the lid 276 and opening / closing it, and can be performed without removing the feeder 130 from the pallet 132.

In the present embodiment, the amount of the cover tape 146 accommodated in the accommodating case 270 is set to a size capable of accommodating the cover tapes 146 for a plurality of reels. It is not necessary to discard 146, and it is sufficient to discard once for each of a plurality of connections. Further, it is not essential that the cover tape 146 is discarded at the same time when the tape-shaped electronic component 142 is connected, and may be discarded at another time. For example, the taped electronic components 14 for all of the connectable feeders 130
After connecting the two, if there is still time, look at the housing case 270 and discard the cover tape 146 if the housing amount is large. Feeder 13 other than connectable feeder
Also for 0, the cover tape 146 may be discarded.

As is clear from the above description, in the present embodiment, the part that determines the wrappable length of the control device 700 constitutes the wrappable length determination part as the wrappable amount determination part, and a plurality of wrappable length determination parts are provided. The portion that acquires the number of remaining components in each of the feeders 130 constitutes the remaining component number acquisition unit, and the portion that acquires the actual length of the taped electronic component based on the electronic component holding pitch and the number of remaining components acquires the actual length. And a part that determines the connectable feeder based on the actual length and the wrappable length of the taped electronic component 142 constitutes the length-dependent connectable feeder determination part, and the remaining number of parts and the number of set parts are set. The part that determines the connectable feeders on the basis of the number of remaining parts constitutes a connectable feeder determining unit that depends on the number of remaining parts, and the number of remaining parts and electronic data for one printed wiring board 30. The part that determines the remaining time based on the number of products supplied constitutes the remaining time determination part, and the part that determines the connectable feeder based on the remaining time and the set time forms the remaining time-based connectable feeder determination part. ing. In addition, the taped electronic component 142 of the control device 700
The part that determines the connection priority based on the actual length of the component constitutes the length-based priority determination unit as the possible / actual amount difference-based priority determination unit, and determines the connection priority based on the number of remaining parts. The part that constitutes the remaining part number-dependent priority order determining unit, and the part that determines the connection priority order based on the remaining time constitutes the remaining time-dependent priority order determining unit. Further, the lamp 204 constitutes an indicator, and the control device 7

Attach to 2.

In the present embodiment, the mounting of the electronic component 934 on the printed wiring board 902 in the electronic component mounting system 901 is performed according to the three component mounting modes as in the above embodiment. Two component feeders 910,
912 indicates the component supply tables 120 and 12 respectively.
The electronic component 934 is supplied as 2. The determination of connectable feeders, the connection priority order, etc. are performed in the same manner.

For example, in the first mode, the electronic component 93
When mounting four, two component supply devices 910, 91
If one of the two parts runs out of parts, the parts holding device 9
The electronic component 30 receives the electronic component from the other, and the electronic component 934 is replenished in the component supply device in which the component has run out. If a taped electronic component is connected to the feeder 918 that has run out of parts and there is a connectable feeder,
Also for this, the taped electronic components are connected. The instruction of the part-out feeder, the connectable feeder, and the instruction of the connection priority are given by turning on and blinking the lamp and displaying on the display screen. The operator is instructed that the taped electronic parts can be connected before the parts run out, and the worker follows the instruction to perform the connection work before the parts run out to attach the electronic parts 934. Can be replenished. In addition, if a predetermined amount of cover tape has accumulated in the storage case, it is taken out.

In the present electronic component mounting system 901, since the component supply devices 910 and 912 are provided with fixed positions, the tape-shaped electronic components can be supplied whether the electronic components 934 are being supplied or not. Can connect parts. The rear portion of the feeder 918 (the component holding device 93
(The side opposite to the supply part where the electronic components are taken out by 0)
The component holding device 930 does not move to the side, and work such as connection of the taped electronic component can be performed. The entire electronic component mounting system 901 is covered by a cover (not shown), but an opening / closing cover is provided at a portion corresponding to the rear portion of each feeder 918 of the component supply devices 910 and 912, so that the operator can open and close the system. Open the cover and connect the taped electronic parts. The operator opens the opening / closing cover based on the notification that it is time to connect the tape, such as running out of parts, and looks at the lamp of the feeder 918. Since the lamp is blinking, the feeder 918 comes first.
18 is replaced and taped electronic parts are connected. The feeder 918 of the component supply device that is supplying the electronic component 934 can also be connected. Therefore, for example, when the electronic component 934 is mounted in the second mode, the electronic component 934 of one component supply device is mounted. After the supply of
Even if the taped electronic components are connected and the connection work is not completed by the time the taped electronic components are supplied by the other component supply device, the supply of electronic components by one component supply device must be started. Can be installed without interruption. Further, by connecting the taped electronic components in the connectable feeder, the occurrence of component shortage can be avoided or reduced. When the electronic component 934 is mounted in the third mode, it is possible to avoid or reduce the occurrence of component shortage by connecting the taped electronic component to the connectable feeder during feeding as well as during standby. You can Even when the electronic components are mounted in the first and second modes, the connection may be performed immediately or when a set number is accumulated if a connectable feeder does not occur during supply. The feeder 918 of the component supply device during component supply
When connecting taped electronic parts, if the supply order of the connectable feeder has changed before the connection of the taped electronic parts is completed, for example, the mounting order (supply order) is changed and the feeder is changed. Parts are supplied after the connection of the taped electronic parts is completed.

In any mode in which the electronic component 934 is mounted, the out-of-component feeder, the connectable feeder, and the like are displayed on the display screen and are instructed by lighting or blinking the lamp provided in the feeder 918. The worker can perform the connecting work quickly and accurately. In addition, the instruction of the connectable feeder and the connection of the tape-shaped electronic components in the connectable feeder allows the electronic components to be replenished earlier, the delay of the replenishment can be avoided, and the supply reliability can be improved.

Also in the embodiment shown in FIGS. 27 and 28, a plurality of feeders may be mounted on a pallet, the pallets may be mounted on a support base, and the feeder together with the pallet may be attached to and detached from the support base. Of course, the pallet may be moved to the work table by a trolley to perform the connecting work of the tape-shaped electronic parts.

In an electronic component mounting system such as the electronic component mounting system 901 in which the component supply device is fixed in position, the plurality of component supply devices may be devices having different electronic component supply modes. For example, one of the two component supply devices is a feeder type component supply device having a feeder for holding the taped electronic component and supplying the electronic component, and the other is a tray type supply device.
The tray-type component supply device is a device in which a large number of housing recesses are provided in a tray, and one electronic component is housed in each of the housing recesses to supply the electronic component. In this case, if a connectable feeder is generated while the electronic component supplied by the feeder-type component supply device is mounted on the printed wiring board, the instruction device instructs the operator to connect the taped electronic component. To be Further, the system may have one feeder type component supply device. In these cases, the electronic component is supplied by only one feeder type component supply device, but the component supply device supplies the electronic component without moving, so that the taped electronic component can be connected at any time during the supply or the rest. The supply of electronic components in advance based on the instruction of the connectable feeder by the instruction device suppresses the occurrence of component shortage and improves the reliability of supply. The operator may connect when one connectable feeder is generated, or may be connected when a set number or more is generated.

In each of the above embodiments, the feeder in which the end of the taped electronic component is detected by the tape end detection device is used as the component shortage feeder, and the electronic component is replenished by replacing the feeder. Regarding the component-cut feeder, the electronic components may be replenished by connecting the taped electronic components. in this case,
For example, if the feeder is a connectable feeder and the supply of electronic components is further continued, the remaining length of the taped electronic components becomes too short, and the feeder that is difficult to perform the connecting work is used as the component shortage feeder. . This out-of-parts feeder
It is a connection-required feeder and a connection limit feeder. The component-out feeder is determined or detected based on, for example, the actual length of taped electronic components remaining in the feeder, the number of remaining components, or the remaining time, similar to the determination of the connectable feeder. If the actual length is less than the set length (connectable length or allowable connection length), the number of remaining parts is less than the set number of parts, and the remaining time is less than the set time,
It is determined that the parts are running out, that is, it is difficult to connect the taped electronic parts. The set length is, for example, the distance between the connection detection position of the feeder (or the extraction portion of the taped electronic component from the reel) and the supply portion, the length required for the connection work, that is, the reel is removed from the feeder, Obtained by setting the auxiliary reel holding device to rewind the taped electronic parts and adding the length required to connect with the new taped connecting parts,
It is set shorter than the wrapping length for determining the connectable feeder. The length of the taped electronic parts from the part located in the feeder supply part to the end should be long enough to connect the taped electronic parts with the feeder still attached to the pallet. is there. The number of set components is set, for example, by dividing the set length by the component holding pitch of the taped electronic component, and is set to be smaller than the set number for determining the connectable feeder. The set time is
For example, the value obtained by dividing the number of set parts by the number of parts that one feeder supplies to one printed wiring board is multiplied by the time required to mount all the electronic parts on one printed wiring board. And is set shorter than the set time for determining the connectable feeder. The number of printed wiring boards capable of supplying electronic components may be compared with the set number. Any of these set values can be determined with the feeder being mounted on the pallet, and the minimum length or a length close to the minimum at which the above-described taped electronic component connecting work can be performed. It is set to the value. The connectable length or the connectable length is preset according to the size and shape of the feeder and can be stored as feeder information. Therefore, the number of set parts, the set time,
The set number of sheets can also be set in advance. For example, if the component holding pitch of the taped electronic components to be held for each feeder is determined, it can be set and stored as feeder information. The mode for determining the connectable feeder and the mode for determining the component shortage feeder, which is the feeder requiring connection, may be the same or different. It is desirable to connect the taped electronic components if any one of the component-cutting feeders capable of connecting the taped electronic components is produced. The portion of the control device that determines or detects the required feeder for connection constitutes the required feeder determination means or the required feeder detection means.

The tape-cut electronic component feeder capable of connecting electronic components is a feeder requiring connection of electronic components, and is a connectable feeder having the first connection order. Therefore, the tape-cut electronic parts are connected due to the occurrence of the component-cut feeder. First, the lamp of the component-cut feeder is blinked to instruct that the connection order is the first, and the tape-cut electronic is indicated by the component-cut feeder. The parts are connected. The connection of the taped electronic components is performed as in the connectable feeder. Then, if there is a connectable feeder other than the component out feeder, the taped electronic components are connected according to the connection priority after the connection of the taped electronic components in the component out feeder is completed. If a feeder that can be connected in this way and is at the limit of the connectable state of taped electronic components is a component-cut feeder, the supply of electronic components is always performed by connecting the taped electronic components. Become. Also,
If any such out-of-stock feeder occurs,
By supplying the parts by connecting the taped electronic parts, it is possible to avoid the occurrence of a situation where the electronic parts are completely lost in the feeder or the parts cannot be supplied by connecting the taped electronic parts. The replenishment of electronic components by connecting the taped electronic components has an advantage that the electronic components can be replenished without wasting the electronic components remaining in the feeder, and the advantages can be fully enjoyed.

In the system in which the feeder is provided on the moving table, even when the feeder requiring connection is the component-cut feeder, the retracted component supply table is moved to the component supply area during the operation of the taped electronic component to move the electronic component. When it is necessary to supply the fuel, the alarm is notified to the operator. At this time, as in the above-described embodiment, the remaining time is calculated for the feeder determined as the connectable feeder, compared with the set time, and when the time is equal to or shorter than the set time, a notification is given. However, when the remaining time is calculated based on the number of remaining parts, the remaining time is obtained from the number of remaining parts by subtracting the number of remaining parts remaining in the state where the feeder becomes the connection-needed feeder. The number of remaining parts remaining when the feeder has become a connection-needed feeder is determined for each feeder based on the length of the taped electronic parts (the connectable length or allowable connection length) and the part holding pitch. Desired.

Further, the supply of the electronic components by connecting the taped electronic components may be performed if the number of connectable feeders does not exceed the set number even if the components run out. first,
The same applies to the case where the electronic component is supplied in any of the second and third modes. As a result, the occurrence of parts shortage is avoided as much as possible. Out-of-parts is also a table replacement command, and the fact that the number of connectable feeders exceeds the set number is also a table replacement command.

Further, it becomes necessary to move the movable table which is being evacuated to the evacuating area to the parts supplying area, and when the fact is notified, if the connection of the taped electronic parts has not been completed for all the connectable feeders. The component supply table that is being retracted may be moved to the component supply area after all the connection work is completed. In this case,
The electronic component supply is stopped because it is not possible to move the retracted component supply table to the component supply area until the component supply table that supplies electronic components in the component supply area runs out of components. The situation may occur. However, for example, if the connecting work of the taped electronic component is performed in a place away from the electronic component mounting system and it takes time to move the feeder between the work place and the electronic component mounting system, the connecting work is performed. Since there is a possibility that parts will frequently run out during the process and parts of the taped electronic parts will not be connected in time at last, even if the supply is interrupted, all taped electronic parts will be connected to the connectable feeders. It can be useful to do so.

In each of the above embodiments, the connectable feeder is based on any one of the real length dependent connectable feeder determination mode, the remaining part number dependent connectable feeder determination mode, and the remaining time dependent connectable feeder determination mode. The connection priority was determined based on one of the real length dependency priority determination mode, the remaining part number dependency priority determination mode, and the remaining time dependency priority determination mode. The connectable feeder may be determined by a combination of the connectable feeder determination modes, or the connection priority may be determined by a combination of a plurality of priority determination modes. In addition, the reasons for relying on the determination of the connectable feeder 130 and the determination of the priority may be different. In either case, the mode used for the decision is selected by the operator.
It may be set in advance. The operator may select from a preset combination, and may be preset depending on the type of the circuit board, for example.

Further, the auxiliary reel holding device that holds the reel for rewinding or winding the taped electronic component from the reel may be a device that rotatably supports the reel on the rotation axis. For example, a rotation shaft is provided in the auxiliary reel holding device, the reel is engaged with the rotation shaft in a relatively non-rotatable manner, and the rotation shaft is rotated by the rotation device to rotate the reel in the forward or reverse direction.

Further, of the pair of side wall portions of the reel accommodating portion of the auxiliary reel holding device, the side wall on the side where the motor is not provided is a movable wall, and it is possible to approach and separate from the fixed wall which is the other side wall. Alternatively, the width of the reel housing portion may be adjusted according to the width of the reel. Notches are provided in portions of the movable wall corresponding to the plurality of rollers so that interference with the rollers is avoided during width adjustment.

Furthermore, the same type of electronic components may be supplied by a plurality of feeders mounted on the same table. In this case, even if one of the plurality of feeders runs out of parts, if there is an electronic component in another feeder that supplies the same type of electronic component, that feeder supplies the electronic component. Therefore, the out-of-component state means that there is no electronic component of any type in the component supply table, and the electronic component is exhausted for all of at least one feeder that supplies the electronic component of the same type.

Further, when there is no electric component to be supplied to the feeder, the feeder may run out of components. In this case, the component shortage detection device can be configured in various ways, for example, may be detected based on the number of supply of electrical components, or the component holder sets the number of electrical components from the same feeder, When it is not possible to continuously perform the processing, it may be possible that the parts run out. Even in such a case, the taped electronic component is not housed at the end, but if the taped electronic component has a portion long enough to perform the tape connection work, the taped electronic component may be connected. Electronic parts can be replenished. At this time, since the electronic components are not accommodated at the end of the taped electronic components currently held in the feeder, after connecting the new taped electronic components, the taped electronic components can be sent automatically or manually to create a new tape. The leading electronic component housed in the chemical electronic component reaches the supply unit.

Further, for example, Japanese Patent Laid-Open No. 2000-1309.
A computer may be provided in each of the plurality of feeders, as described in Japanese Unexamined Patent Application Publication No. 2004-242242. The plurality of feeder computers exchange information with or are supplied to the system computer 702 directly or indirectly via another computer. In this case, the number of remaining parts on the reel can be managed for each feeder.
Also, a computer may be provided on the mobile table, and the pallet computer may exchange data with the system computer via the mobile table computer. Alternatively, if the pallet is not provided, information may be exchanged between the mobile computer and the feeder computer. The same applies to the case where the feeder is supported by a feeder support base fixed in position via a pallet or directly.

Also, the mobile platform moving device may be shared by a plurality of mobile platforms.

Further, when the feeder is mounted on the pallet, the electric parts may be replenished by replacing the feeder with the pallet. In this case, a plurality of sets, for example, two sets of pallets in which the same kind of feeders are mounted in the same order are prepared, and a pallet in which a feeder for connecting taped electric parts is mounted and a feeder in which connection is already completed are mounted. Replace with a pallet. The taped electrical parts are connected to the pallet feeder removed from the stand.

The pallet may be smaller than the moving table, and a plurality of pallets may be mounted on the moving table. In this case, the replenishment of electronic components is first performed for a pallet having a feeder that has run out of components, and then for a pallet having only connectable feeders. If there is a feeder that can be connected to a pallet with a feeder that has run out of parts, tape connection may also be performed for that feeder,
It may be performed when the connection priority is high. If there are a plurality of pallets having only connectable feeders, for example, among at least one connectable feeder that each of the plurality of pallets has, the feeders with the highest priority are compared with each other, and the feeders with a high priority among the plurality of pallets are compared. The taped electronic parts are connected by sequentially removing the pallet from the moving table. The connection priority of the connectable feeders and the connection priority among the pallets are displayed by a display device or the like. It is also possible to use a plurality of carts and connect the taped electronic components to the feeders that can be simultaneously connected in parallel for a plurality of pallets.
The same applies when the feeder is mounted on a pallet, and the components are supplied by being supported by a feeder support base that is fixed in position and the components are removed from the feeder support base together with the pallet and taped electronic components are connected. Is.

Further, the pallet support base provided on the moving base of the component supply apparatus may be composed of a plurality of support members. For example, on both sides of the moving table, which are separated from each other in the moving direction, support members that are long in the front-rear direction of the moving table and are perpendicular to the moving direction are provided so as to be able to move up and down with respect to the moving table. Each of these support members is provided with a plurality of support rollers, guide rollers, clamps, and the like, and is simultaneously lifted and lowered simultaneously by an elevator device similar to the support platform elevator device 450. The lifting and lowering of the support member is guided by a guide device including a pair of guide bars and guide blocks.

Furthermore, a plunger ball may be provided on the pallet support of the truck to prevent the pallet from being pulled out with certainty. The plunger ball constitutes a pallet pull-out prevention device, is provided on the pallet support base at a position apart from the stopper in the pallet transfer direction, and is provided in the casing so as to be movable in the vertical direction and the ball of the casing. A spring (not shown) as an elastic member that is a kind of a biasing device that biases in a direction of protruding from the opening is provided. The withdrawal of the ball from the casing is prevented by the engagement portion provided in the opening of the casing engaging with the ball. A part of the ball always protrudes upward from the casing and fits into a recess provided on the lower surface of the pallet to prevent the pallet from being removed from the trolley. It is pushed by the inclined inner surface of the pallet, retracts into the casing against the urging force of the spring, and separates from the recess, allowing the pallet to move.

When the punched electronic component is used as the taped electronic component, the tape end detection device may be composed of a transmissive photoelectric sensor. In this case, the light emitting portion and the light receiving portion of the photoelectric sensor are arranged on both upper and lower sides with the passage of the feed hole of the taped electronic component interposed therebetween, and the taped electronic component passes between the light emitting portion and the light receiving portion. Are led to the supply section. When there is a taped electronic component, the light emitted from the light emitting part is received by the light receiving part after passing through the sprocket hole and when the transmission is blocked by the part of the carrier tape where the sprocket hole is not provided. The amount changes periodically, but if the taped electronic parts are gone, the light receiving part will continue to receive light, the amount of received light will not change, and the output signal of the tape end detection device will not change, so the taped electronic parts will not change. The end of is detected. The tape end detection device may be configured by a contact type micro switch which is a kind of contact type sensor.

The taped electronic component may be a so-called embossed type. In the embossed type electronic component of tape type, the carrier tape has a supported portion extending in the longitudinal direction on both sides in the width direction, and projects downward from both the supported portions between the supported portions and has a constant pitch in the longitudinal direction. And a large number of electric component accommodating portions formed by. Each of these electric component accommodating portions is formed with an accommodating recess that opens upward to accommodate one electric component, and the opening of the accommodating recess is covered with a cover tape. This taped electronic component is supported from below by a pair of supported portions. For example, a large number of feed holes are provided in one supported portion at a constant pitch, and the taped electronic component is fed by a feeding device like the taped electronic component 142. To be

When the taped electronic component is an embossed type, the tape end detection device is composed of, for example, a transmissive photoelectric sensor. In this case, the photoelectric sensor is provided at a portion where the housing recess passes in the width direction of the passage for the taped electronic component. The carrier tape of the taped electronic component is formed of a synthetic resin, and when the portion of the taped electronic component in which the electronic component is accommodated passes, the electronic component prevents transmission of light and the amount of received light is zero. On the other hand, in the part between the adjacent accommodating recesses of the carrier tape, when the part without the electronic component passes, the light is transmitted and the light receiving part receives the light, and while the taped electronic component is present, It can be seen that the amount of received light changes periodically, but when the taped electronic parts are gone, the amount of received light does not change, and the taped electronic parts are gone. Even when the taped electronic component is an embossed type, the tape end detection device may be configured by a reflection type photoelectric sensor or a contact type sensor.

In connecting the taped electronic parts in each of the above-mentioned embodiments, the carrier tape was connected by the metal tape connecting member and the cover tape was connected by the synthetic resin connecting tape. 9-2467
As described in JP-A-80 and JP-A-2000-13092, both the carrier tape and the cover tape may be connected by a connecting tape which is a connecting member. In this case, for example, Japanese Patent Laid-Open No. 2000-1
As described in Japanese Patent No. 3092, a connection tape for connecting a carrier tape can be detected by being optically distinguished from the carrier tape, and a connection portion of two taped electronic parts is a transmission type photoelectric sensor, Reflective photoelectric sensor,
It is detected by an optical connection detecting device such as a color sensor. For example, if the taped electronic component is a punch carrier type, and the paper base tape of the carrier tape is a color with a large amount of reflected light (for example, white), the connection tape is a color with a small amount of reflected light (for example, black). And attach the connecting tape to the part of the carrier tape where the sprocket hole is provided. 2
Each carrier tape of one taped electronic component is connected.
A feed hole similar to the feed hole of the carrier tape is provided at a portion corresponding to the feed hole of the connection tape, and the connection tape is attached to the carrier tape in a state where the feed holes match. The reflective photoelectric sensor is provided on one side of the passage of the tape-shaped electronic component, that is, on one side in the thickness direction and on either side of the upper side and the lower side. The element is provided at a position corresponding to the connection tape in the width direction of the feeder (a position corresponding to a portion of the carrier tape where the feed hole is provided). When a portion of the carrier tape other than the portion connected by the connecting tape passes over the photoelectric sensor, the light emitted by the light emitting element is reflected by the portion of the carrier tape where the feed hole is not provided and is received by the light receiving element and sent. While the amount of received light is not reflected at the portion where the hole is provided and changes periodically, when the connecting tape passes, the light is absorbed by the portion of the connecting tape where the sending hole is not provided, and the sending hole Since the light is not transmitted and reflected at the portion where is provided, the amount of received light does not change and remains small. Due to this difference, the connection tape is detected and the connection portion of the tape-shaped electronic component is detected.

When the taped electronic component is an embossed type, the carrier tape may be connected to at least one of the pair of supported portions by at least one of the tape connecting member and the connecting tape. The cover tapes are connected by connecting tapes. When the carrier tape is connected by the metal tape connecting member, the tape connecting member is detected by the connecting portion detecting device including the metal detector as described above,
Detect connections. When the carrier tape is connected only by the connecting tape, the connecting portion can be detected by, for example, detecting the connecting tape attached to the cover tape. When the carrier tape and the cover tape are made of transparent synthetic resin, by making the connection tape made of opaque synthetic resin, for example, the connection tape attached to the cover tape is detected by a transmissive photoelectric sensor, Detect connections. In this case, when the portion of the cover tape to which the connecting tape is not attached passes through the photoelectric sensor, the amount of received light is periodically changed depending on whether the electronic component passes or the portion not containing the electronic component passes. On the other hand, when the connection tape passes, the transmission of the light is continuously hindered, and the connection portion is detected because the light reception amount remains small and does not change.

Even when the tape carrier electronic component is of the punch carrier type, the connecting tape attached to the cover tape may be detected to detect the connecting portion. In the case of detecting the connecting portion by detecting the connecting tape for connecting the cover tape, for example, as described in the application of Japanese Patent Application No. 2002-326942 related to the present applicant, which has not been disclosed yet, In addition, a color portion that is detected by being distinguished from the parts accommodated in the carrier tape is provided, and the connection tape is detected by the difference in the amount of light received by the reflection type photoelectric sensor provided above the passage of the cover tape. , The connection part is detected.

Even when the carrier tape is connected by the metal tape connecting member, the tape connecting member may be detected by the optical connecting portion detecting device. The light reflectance and color of the carrier tape and the tape connecting member are set so that they can be clearly distinguished and the tape connecting member can be detected.
