The picked-up empty tape 122a passes through the front of the electric tape feeder (the right side in Fig. 13) and is discharged downwardly as if it is a natural drop.

As described above, the tape ejection path differs depending on the method of driving the tape feeder. Therefore, when the electric tape feeder 120 using the motor-driven batch exchange carriage 121 shown in Fig. 13 is mounted on the main body of the electronic component mounting apparatus to which the machine-driven tape feeder 110 shown in Fig. 12 is attached, The drive mechanism such as the knock cylinder 201 fixed to the mounting apparatus main body blocks the tape discharging path of the electric tape feeder 120, so that the electric tape feeder 120 can not be used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First Embodiment)

(Configuration)

The component mounting apparatus 1 is configured such that the component supplying apparatus 3 for supplying electronic components can be separated and connected. Further, in the present embodiment, the component feeding device 3 can be used in combination of two types of machine driving method and electric driving method.

In the component feeding device 3 of the machine driving type shown in Fig. 1, a machine-driven batch exchange carriage 31 is disposed. The batch exchange carriage 31 can freely move horizontally on a floor surface by a caster 31a and a machine driven feeder bank 33 is provided in the batch exchange carriage 31. [

The machine-driven feeder bank 33 has a plurality of machine-driven tape feeders 32 detachably attached in a parallel state, and is configured to be vertically movable up and down. The machine-driven feeder bank 33 is detachably attached to the component mounting apparatus 1 Respectively.

Although not shown, a known component tape made of a tape main body and a cover tape is wound and held by the tape cartridge 34 provided on the machine-driven tape feeder 32. [ The component tape has a component housing part for housing a plurality of components at a predetermined interval in the tape main body, and a cover tape is coated and bonded to cover the parts housing part. When the component tape is pulled out from the tape cartridge 34 and is guided to the pick-up position P in front of the feeder, the cover tape can be peeled off from the tape body just before the pickup position P, The component is suctioned by the component suction nozzle of the mounting apparatus 1. [

After the component is sucked, the component tape is unrolled and transported by a predetermined amount by a predetermined predetermined feeding mechanism (not shown) having, for example, a knock lever and a ratchet. Specifically, a knock lever is disposed below the pick-up position P in the machine-driven tape feeder 32, and the ratchet is rotated in a predetermined direction in accordance with the rocking motion of the knock lever to release the tape by a predetermined amount.

In the present embodiment, a driving power source for driving the feeding mechanism of the machine-driven tape feeder 32 is provided on the component mounting apparatus 1 side.

2 is that the electric tape feeder 52 is mounted on the component mounting apparatus 1 by using the motor-driven batch exchange carriage 51. The component-

The motor-driven batch exchange carriage 51 is freely movable horizontally on the floor surface by the caster 51a, and the motorized feeder bank 53 is fixedly held.

The electric feeder bank 53 holds the plurality of electric-tape feeders 52 in a detachable state in a parallel state, and is configured to be vertically movable up and down. The motor-driven batch exchange carriage 51 is detachably mounted on the component mounting apparatus 1.

The electric tape feeder (52) has a tape cartridge (54). The tape cartridge 54, like the tape cartridge 34 of the mechanical drive type, is made of a tape main body and a cover tape, and holds a tape containing a plurality of parts at a predetermined interval in a wound state. The tape led out from the tape cartridge 54 is guided to the pickup position P so that the cover tape is peeled from the tape main body immediately before the pickup position P to take out the component.

After the component is adsorbed, the tape is released by a predetermined amount by a predetermined feeding mechanism. Here, although not particularly shown, a rotating body such as a sprocket is used as a feeding mechanism.

Specifically, a sprocket to be engaged with the tape is disposed below the pickup position P in the electric tape feeder 52, and the sprocket is rotated by the electric motor serving as a driving power source for driving the feeding mechanism to move the tape It releases a certain amount.

As described above, the component feeding device 5 is provided with a driving power source for driving the feeding mechanism of the electric tape feeder 52.

Next, the configuration of the component mounting apparatus 1 will be described.

The component mounting apparatus 1 is provided with a driving power section 10 which is a power source for driving a feeding mechanism of the machine-driven tape feeder 32. The drive power section 10 includes knock pins 11 arranged in the tape feeder arrangement direction (X direction) by the number corresponding to the number of tape cartridges 34 that can be installed on the feeder bank 33, And a knock cylinder (12) for raising and lowering the knock pin (11).

The knocking cylinders 12 are arranged in the same number as the knock pins 11 in the longitudinal direction (left and right direction in FIG. 4), and can be operated by air supply and air-down individually by a control unit described later.

In the present embodiment, the driving power section 10 is configured to be movable in the vertical direction, and the type of the tape feeder mounted on the component mounting apparatus 1 (the machine-driven tape feeder 32 or the electric tape feeder 52 )), As shown in Fig.

That is, the component mounting apparatus 1 includes a knock cylinder fixing table 13, an air cylinder 14, and a guide rail 15 in order to configure the driving power section 10 to be movable up and down.

The air cylinder 14 is disposed in the front lower side of the tape feeder installation position. Here, it is assumed that the air cylinders 14 are arranged in the X-direction both ends of the component mounting apparatus 1, respectively. The air cylinder 14 is supplied with air and air-down by a control unit, which will be described later.

A knock cylinder fixing table 13 is fixed to the front end of the driving unit of the air cylinder 14 and knock cylinders 12 are attached to these knock cylinder fixing stands 13, respectively.

The guide rails 15 are located at both sides of the tape discharge path and are disposed on both sides of the knock cylinder 12 and exist in the Z direction of the component mounting apparatus 1. The guide rails 15 are provided with knock cylinders 12 are engaged with each other.

With this configuration, by controlling the air in the air cylinder 14, the knocking cylinder 12 is guided by the guide rails 15 and linearly moves in the vertical direction.

When the electric tape feeder 52 is mounted on the component mounting apparatus 1, the knocking cylinder 12 is moved to the initial position shown in Fig. 4 (a) by keeping the air cylinder 14 in the initial state of air- Second placement position). When the mechanical drive type tape feeder 32 is mounted on the component mounting apparatus 1, air is supplied to the air cylinder 14 so that the knock cylinder 12 is moved to the initial position as shown in Fig. 4 (b) (First placement position) that is moved upward by a predetermined height H from the position.

The second arrangement position is such that the knock pin 11 and knock cylinder 12 do not interfere with the tape ejection path described later in the electric tape feeder 52 as shown in Fig.

9, the knock pin 11 is positioned at a position at which the knock pin 11 can be connected to a feeding mechanism (not shown), that is, The position where the operation can be performed is assumed.

3, the component mounting apparatus 1 includes a feeder bank mounting base 16 and a feeder bank cylinder 17 having a drive end fixed to the feeder bank mounting base 16.

When the component feeder 3 or 5 is mounted on the component mounting apparatus 1 by using the batch exchange carriage 31 or 51 on the feeder bank mounting table 16, One feeder bank 33 or 53 is installed.

The cylinder 17 for the feeder bank is supplied with air and downed by the control unit, which will be described later. When air is supplied to the cylinder 17 for the feeder bank, the feeder bank rises up to a predetermined component supply position for supplying and mounting the components. At this time, the feeder bank is set by supporting the feeder bank by the opposing member 18 disposed opposite to the feeder bank mounting base 16 and the feeder bank mounting base 16.

A contact type bank check switch 19 is fixed on the lower surface of the opposing member 18 (the surface facing the feeder bank mounting table 16) to discriminate the type of the tape feeder mounted on the component mounting apparatus 1 have. The bank check switch 19 outputs an ON signal by contact with the feeder bank.

Driven feeder bank 33 is set at the component feed position of the component mounting apparatus 1 as shown in Fig. 5 (a) The top surface touches. At this time, as shown in FIG. 5 (b), the bank check switch 19 is turned on by pressing the bank check switch 19 on the upper surface of the machine-driven feeder bank 33.

6 (a), the lower surface of the opposed member 18 and the upper surface of the electric feeder bank 53 are connected to each other at the component supply position of the component mounting apparatus 1, The bank confirmation switch 19 is kept in the OFF state by forming the hole 53a as shown in Fig. 6 (b) in order to prevent the bank confirmation switch 19 from contacting the electric feeder bank 53 .

Therefore, the bank check switch 19 outputs a signal different depending on the type of the tape feeder set at the component feed position.

7, the ON / OFF signal of the bank check switch 19 and the set-up signal of the set-up switch 21 are inputted to the control unit 20. [ The set-up switch 21 is a switch provided at a predetermined position of the component mounting apparatus 1 and operated by an operator when the component supplying apparatus 3 or 5 is detachably connected.

The control unit 20 includes a storage unit (ROM) for storing various programs or data in advance, a storage unit (RAM) for storing input data or the like, or a processor unit (CPU) .

The control unit outputs an air supply command signal and an air down command signal to the cylinder 17 for the feeder bank, the air cylinder 14, and the knock cylinder 12 based on the input signal.

In the flowchart shown in Fig. 8, the processing procedure executed by the control unit 20 will be described.

First, the set-up signal of the set-up switch 21 is read and it is judged whether or not the set-up switch 21 is in the ON state (step S1). When it is determined that the set-up switch 21 is in the ON state, the air supply command signal is outputted to the cylinder 17 for the feeder bank (step S2 ). Thereby, the cylinder 17 for the feeder bank is operated to raise the feeder bank mounting table 16, and the feeder bank provided on the feeder bank mounting table 16 is raised to the component feeding position.

Next, the ON / OFF signal of the bank identifying switch 19 is read and it is judged whether or not the bank identifying switch 19 is in the ON state (step S3). When the feeder bank is in contact with the bank check switch 19 and the bank check switch 19 is in the ON state, it is assumed that the feeder bank mounted on the component mounting apparatus 1 is the machine driven feeder bank 33, An air supply command signal is outputted to the air cylinder 14 to supply air to the air cylinder 14 (step S4). By the supply of air to the air cylinder 14, the knock cylinder 12 is raised to the position shown in Fig. 4 (b) and the setting up is completed (step S5).

On the other hand, in step S3, when the bank check switch 19 is in the OFF state because the feeder bank is not in contact with the bank check switch 19, the feeder bank mounted on the component mounting apparatus 1 is connected to the electric feeder bank (53), and the process directly proceeds to step S5.

When the set-up of the tape feeder is completed, the program (subroutine) of the component mounting process is activated to prepare for start-up (step S6). For example, when the component feeding apparatus 3 is mounted on the component mounting apparatus 1 (when the bank check switch 19 is ON), the tape feeder 32 is controlled so as to feed the component from the machine- The knock cylinder 12 is designated as the drive power source of the knock cylinder. Specifically, the knock pin 11 is moved up and down by repeatedly instructing air supply and air-down to the knock cylinder 12 to release the tape of the machine-driven tape feeder 32 by a predetermined amount, To pick up the component from the tape at the pick-up position P and mount it on a predetermined position on the substrate.

When the component feeding apparatus 5 is mounted on the component mounting apparatus 1 (when the bank check switch 19 is OFF), the tape feeder is driven so as to supply the component from the electric tape feeder 52 And designates an electric motor provided in the component supply device 5 as a power source.

Specifically, by repeatedly instructing driving and stopping of the electric motor, the tape of the electric tape feeder 52 is unloaded by a certain amount, and the component suction nozzle is controlled to attract the component from the tape at the pickup position P, And is mounted at a predetermined position.

As described above, the component mounting process is performed by the driving method according to the type of the tape feeder to be mounted. When the supply of the components from the tape feeder is completed, the component mounting process is terminated (step S7). Here, the component mounting process is completed by performing air-down of the knock cylinder 12, which is the driving power source of the tape feeder, and stopping the electric motor.

Next, the set-up signal of the set-up switch 21 is read and it is judged whether or not the set-up switch 21 is in the OFF state (step S8). When the set-up switch 21 is in the ON state, it waits until it becomes the OFF state. When the OFF state is determined, the air-down command signal is outputted to the feeder bank 17 (step S9) . The cylinder 17 descends the feeder bank mounting table 16, so that the feeder bank provided on the feeder bank mounting table 16 descends.

Next, the ON / OFF signal of the bank identifying switch 19 is read to determine whether the bank identifying switch 19 has changed from the ON state to the OFF state (step S10). When the bank check switch 19 is in the OFF state, the process is terminated as it is.

On the other hand, when the bank check switch 19 is changed from the ON state to the OFF state, an air down command signal is outputted to the air cylinder 14 (step S11), and the processing is terminated. Due to the air-down of the air cylinder 14, the knock cylinder 12 is lowered to the initial position shown in Fig. 4 (a).

The drive power section 10 corresponds to the tape conveying means and the knock cylinder fixing table 13, the air cylinder 14 and the guide rail 15 correspond to the elevating means. .

(action)

Next, the operation of the present embodiment will be described.

First, the component feeding device 3 or 5 is set in the component mounting apparatus 1 by using a batch exchange carriage having a new tape feeder mounted on the feeder bank. Then, the batch exchange carriage is positioned with the feeder bank mounted on the feeder bank mounting table 16 provided in the component mounting apparatus 1. [ In this state, when the operator presses the set-up switch 21 installed in the component mounting apparatus 1, the component mounting apparatus 1 starts setting up the tape feeder.

Specifically, by pressing the set-up switch 21 by the operator, the control section 20 of the component mounting apparatus 1 confirms the set-up signal to be turned on (Yes in step S1 in Fig. 8). Then, air is supplied to the cylinder 17 for the feeder bank to raise the feeder bank mounting table 16, and the feeder bank provided on the feeder bank mounting table 16 is raised to a position where the feeder bank abuts the opposing member 18 . Thereby, the feeder bank is set to the component feeding position.

Here, it is assumed that the component feeding apparatus set on the component mounting apparatus 1 is the component feeding apparatus 3 having the machine-driven tape feeder 32 of the mechanical driving type. 5 (b), the upper surface of the machine-driven feeder bank 33 is connected to the bank check switch 19 provided on the lower surface of the opposing member 18 .

For this reason, the control unit 20 confirms that the bank check switch 19 is in the ON state (Yes in step S3). Air is supplied to the air cylinder 14 to move the knocking cylinder 12 upward along the guide rails 15 provided on the left and right of the component mounting apparatus 1 so that the knocking cylinder 12 is rotated b). That is, the knocking cylinder 12 is located at a position below the machine-driven tape feeder 32 and at a position at which the knock lever of the machine-driven tape feeder 32 can swing (I.e., a position capable of performing a releasing operation).

In this manner, the machine-driven tape feeder 32 is set up.

Next, the component mounting apparatus 1 performs component mounting processing for picking up the component from the tape of the machine-driven tape feeder 32 at the pick-up position P and placing the component at a predetermined position on the substrate.

At this time, the control unit 20 repeatedly performs air supply and air down to the knocking cylinder 12 to move the knocking pin 11 up and down, and the mechanical drive system driven by the up and down movement of the knocking pin 11 The feeding mechanism in the tape feeder 32 feeds the tape containing the component from the tape cartridge 34 at a constant pitch. As a result, the parts are arranged in the pickup position P in order. 9, the empty tape Tm after the component is picked up at the pick-up position P passes through the tape discharge path provided inside the machine-driven tape feeder 32, And is discharged from the rear.

In this manner, the components are supplied from the machine-driven tape feeder 32.

On the other hand, when the component feeding device 5 having the electric-powered tape feeder 52 of the electric driving type is set in the component mounting apparatus 1, when the operator presses the set-up switch 21, The electric feeder bank 53 is raised to the component feed position. At this time, the upper surface of the electric feeder bank 53 comes into contact with the lower surface of the opposing member 18. Since the electric feeder bank 53 has the hole 53a as shown in Fig. 6 (b) The bank 53 is not in contact with the bank check switch 19.

For this reason, the control unit 20 confirms that the bank check switch 19 is in the OFF state (No in step S3). In this case, the knock cylinder 12 is stopped at the initial position shown in Fig. 4 (a) without supplying air to the air cylinder 14.

Next, the component mounting apparatus 1 performs component mounting processing for picking up a component from the tape of the electric tape feeder 52 at a pick-up position P and placing the component at a predetermined position on the substrate.

At this time, the control unit 20 repeatedly controls driving / stopping of the electric motor provided in the electric tape feeder 52 to send the tape containing the component from the tape cartridge 54 at a constant pitch. As a result, the parts are arranged in the pickup position P in order. The empty tape Te after the component is picked up at the pick-up position P is transferred from the front of the electric tape feeder 52 to the knock cylinder (Fig. 10) stopped at the initial position with the electric feeder bank 53 12, and is discharged to the lower side of the component mounting apparatus 1. [

In this manner, the components are supplied from the electric tape feeder 52.

[0003] In general, a component mounting apparatus that can use a component-supplying apparatus of a mechanical driving type is provided with a driving power section for performing a feeding operation for unloading a tape through a mechanical drive type tape feeder. And is fixed at a position where a feeding operation can be performed. Therefore, when a component feeding device of the electric driving type is to be connected to the component mounting apparatus, the driving power section fixed to the component mounting apparatus side interferes with the connection, and the driving power section is connected to the tape discharging path . Therefore, in such a conventional component mounting apparatus, the electric tape feeder can not be used.

On the other hand, in the present embodiment, the knock pin 11 and the knock cylinder 12 (driving power unit 10) provided on the component mounting apparatus 1 side can be moved in the vertical direction.

When the mechanical drive type tape feeder 32 is mounted on the component mounting apparatus 1, the knock pin 11 and knock cylinder 12 (drive power section 10) As a result, the machine-driven tape feeder 32 is moved to a position where a feeding operation for unloading the tape on the lower front side can be performed. Therefore, in this case, it is possible to suitably carry out the feeding operation of loosening the tape of the machine-driven tape feeder 32 by the driving power section 10 provided on the component mounting apparatus 1 side.

Further, since the driving power section 10 is provided on the component mounting apparatus 1 side, it is possible to use a general mechanical driving type component feeding apparatus that does not include a driving power source for performing a feeding operation for unloading the tape. There is no need to retrofit the feeder.

4 (a), when the electric tape feeder 52 is mounted on the component mounting apparatus 1, the knock pin 11 and the knock cylinder 12 (the driving power section 10) And is located at an initial position provided below the tape ejection path of the electric tape feeder 52. Therefore, it is possible to prevent the driving power section 10 provided on the component mounting apparatus 1 from blocking the tape discharging path of the electric tape feeder 52, and thereby secure the tape discharging path. Therefore, even a general electric driving type component feeding apparatus that discharges the empty tape to the lower side of the component mounting apparatus through the front of the tape feeder can be used.

As described above, the component mounting apparatus 1 according to the present embodiment does not require extensive modification of the apparatus, and can use tape feeders of different driving methods in combination.

(effect)

As described above, in the above-described embodiment, the driving power section for performing the feeding operation for releasing the tape of the machine-driven tape feeder is configured to be movable in the vertical direction. Therefore, according to the driving method of the tape feeder connected to the component mounting apparatus The drive power section can be moved to an appropriate position.

When the tape feeder is determined to be a machine-driven tape feeder, the tape feeder is driven to a position where the tape feeding operation for unloading the tape of the machine-driven tape feeder can be performed The power section is raised. Therefore, the driving power section provided on the component mounting apparatus side can perform the feeding operation of releasing the tape by the machine-driven tape feeder, thereby making it possible to use the machine-driven tape feeder.

When it is determined that the connected tape feeder is a motorized tape feeder, the drive power section is left at the initial position without being raised. Therefore, it is possible to prevent the mounting of the electric drive type tape feeder from being hindered by the drive power section provided on the component mounting apparatus side. Further, by setting the initial position to a position that does not interfere with the tape ejection path of the electric tape feeder, the driving power portion can be disposed outside the tape ejection path. Therefore, even if an electric tape blower having a tape discharge path in front of the tape feeder is used, it can be suitably used.

Moreover, since the driving power section is disposed below the tape feeder before connection, even if an operation failure occurs in the air cylinder for lifting and lowering the driving power section, the failure of the apparatus can be suppressed. In other words, when the initial position of the drive power section is set to a position where the tapping operation for unscrewing the tape of the mechanical drive type tape feeder is performed, if the drive cylinder does not operate properly when the electric tape feeder is connected, The tape of the tape feeder is clogged and the possibility of failure of the device increases. On the other hand, when the initial position of the driving power section is set to be downward, the air cylinder is not operated properly during the connection of the machine-driven tape feeder, and the feeding operation for loosening the tape of the machine- It is possible to suppress the failure of the apparatus and the like.

In addition, since the ON / OFF state of the switch is changed according to the driving method by using the bank check switch in order to discriminate the driving method of the tape feeder, it is possible to provide a relatively simple structure in which either the machine driven tape feeder or the electric tape feeder It is possible to judge whether or not it is connected.

At this time, since the feeder bank is constructed so as to be able to move up and down in the vertical direction, when the feeder bank is set up from the initial position on the batch exchange carriage to the component feed position, whether or not the feeder bank is in contact with the bank check switch, It is possible to appropriately determine the driving method.

(Application example)

Although the knock pin 11 and the knock cylinder 12 are positioned below the discharge path in the electric drive system in the above embodiment, the air cylinder 14 may be disposed above the discharge path, .

The component mounting apparatus 1 or the component mounting apparatus 1 may be mounted on both sides of the component mounting apparatus 1 on both sides (the front side and the back side) It may be configured to be mountable. At this time, a component feeding device of the same driving system may be mounted on the front side and the rear side, and a component feeding device having different driving methods may be mounted on the front side and the rear side.

In the above embodiment, the case of discriminating the driving method of the tape feeder by using the bank identifying switch 19 has been described. However, even if the driving method is discriminated by the identification of the connector at the time of connecting the collective exchange carriage Do.

Furthermore, in the above-described embodiment, the case where the determination of the rise / fall of the knock cylinder 12 is electrically performed by the bank check switch 19 has been described. However, in the switching of the air circuit by the mechanical drive type mechanical valve . 11, on the supply path to the air cylinder 14 for moving the knock cylinder 12 up and down, a three-port type mechanical drive type mechanical valve, that is, a mechanical drive type / 25). Then, the supply of air to the air cylinder 14 is switched depending on whether the mechanical drive / electric motion discrimination switch 25 is depressed.

When the tape feeder set on the component feeder is in contact with the machine-driven tape feeder 32 as in the case of the bank check switch 19, the mechanical drive / 52), it is configured to be in a non-contact state.

Then, the mechanical drive type / electric motor discrimination switch 25 is normally kept in the closed state shown in Fig. 11, and the supply of air to the air cylinder 14 is cut off. Therefore, at this time, the knock cylinder 12 is placed in the initial position shown in Fig. 4 (a). When the mechanical drive type tape feeder 32 is mounted in this state, the mechanical drive type / electric motion discrimination switch 25 is opened and the air cylinder 14 and the air supply source are communicated with each other. As a result, air is supplied to the air cylinder 14, and the knock cylinder 12 is raised to the state shown in Fig. 4 (b).

On the other hand, when the electric tape feeder 52 is mounted, since the mechanical drive / electric motion discriminating switch 25 is not depressed, the closed state is maintained and the supply of air to the air cylinder 14 is maintained . Therefore, the knock cylinder 12 maintains the initial state of Fig. 4 (a).

Since the pneumatic circuit of the air cylinder 14 is switched in accordance with the contact with the connected tape feeder in this way, it is possible to appropriately perform the determination of the driving method of the tape feeder and the control of the raising and lowering of the knock cylinder 12 have.

Further, in the above-described embodiment, a lock mechanism for preventing the knock cylinder 12 from rising is provided. When it is determined that the electric tape feeder 52 is attached, the lock mechanism is operated to mechanically move the knock cylinder 12 may be prevented from rising. As a result, it is possible to prevent the knock cylinder 12 from erroneously rising due to the malfunction of the air cylinder 14, thereby improving the reliability of the apparatus.

In the above embodiment, whether the mounted tape feeder is the machine-driven tape feeder 32 or the electric tape feeder 52 is automatically discriminated by the bank identifying switch 19 and the driving power section 10 is raised The operator may instruct the operator to indicate whether or not the driving power section 10 needs to be raised or lowered. As a result, for example, when a machine-driven tape feeder having a drive power section is mounted, the drive power section 10 provided on the component mounting apparatus 1 can be prevented from being raised, There is a number.
