Each of the one or more feeders 18 is held by the feeder holding member 24 side by side in the x direction in a posture in which the longitudinal direction of the feeder main body 30 is the y direction. In this state, the feeder 18 and the feeder holding member 24 are electrically connected, and the feeder 18 is electrically connected to the power supply of the electronic circuit assembly device and the control device.

The feeder 18 supplies the lead component P shown in FIG. 10 by using the taped component TP, and as shown in FIG. 3, the guide rail 32 for guiding the taped component TP and the feeder main body 30 It includes a feeding device 36, a part clamp device 38, a lead cutting device 40 and the like provided.

The taped component TP is a plurality of lead components P held by the carrier tape CT, and the lead components P are a component body PB and a plurality of (two, for example, two) extending in one direction from the component body PB. And the lead L of the The lead parts P are held by the carrier tape CT at equal intervals d, and the carrier tapes CT are provided with feed holes at equal intervals d.

The feeding device 36 feeds the taped component TP along the guide rail 32, and as shown in FIG. 3, includes a cylinder 41 as a driving source, a feed claw 42 and the like. The feed pawl 42 is inserted into a feed hole bored in the carrier tape CT, and the actuation of the cylinder 41 moves the feed pawl 42 toward the component supply position SS by one pitch. As a result, the carrier tape CT is fed one pitch at a time, and the lead parts P are fed one pitch at a time. The component supply position SS means a position at which the feeder 18 supplies components to the component insertion device 16.

The component clamp device 38 is provided at the component supply position SS, and clamps the component body PB of the lead component P that has reached the component supply position SS. With the component body PB clamped by the component clamp device 38, the lead L of the lead component P is cut and picked up by the

working heads

20 and 21.

As shown in FIGS. 4 and 5, the component clamp device 38 connects the air cylinder 44 as a drive source, the backup block 46 and V block 48 constituting the pair of clamp members 45, and the V block 48 and the air cylinder 44. It includes a link mechanism 50 and the like. The air cylinder 44 includes a cylinder body 44a, a piston 44p held so as to be movable relative to the cylinder body 44a, and a piston rod 44b movable integrally with the piston 44p. The V block 48 is connected to the piston rod 44 b via the link mechanism 50, and is brought closer to and away from the backup block 46 by the operation of the link mechanism 50 accompanying the operation of the air cylinder 44. The air cylinder 44 is operated by the feeding device 36 every time the taped component TP is fed by one pitch, and the pair of clamp members 45 are made to approach each other.

FIG. 5 shows the separated state in which the pair of clamp members 45 are separated from each other. From this state, as the piston 44p is pulled in the direction of the arrow X, the V block 48 is moved along the pair of

guide rods

51 and 52 via the link mechanism 50 and is made to approach the backup block 46. This state is referred to as the approaching state of the pair of clamp members 45. Then, when the lead component P exists at the component supply position SS in the approach state of the pair of clamp members 45, the component body PB of the lead component P is clamped by the pair of clamp members 45, as shown in FIG. Ru. On the other hand, when the lead component P does not exist at the component supply position SS, the lead component P is not clamped by the pair of clamp members 45, and the V block 48 approaches the backup block 46 to the approach limit. .

A component sensor 54 is provided in the cylinder body 44a. The component sensor 54 detects the relative position of the piston 44p with respect to the cylinder body 44a. In the separated state, the V block 48 is in the position shown in FIG. 5 and the piston 44p is in the position Y0. On the other hand, in the approaching state, when the lead part P is clamped, the piston 44p is at the position Y1, but when the lead part P is not present, the piston 44p has the moving end (for example, the piston 44p is shown) (Not to be in contact with the bottom of the cylinder body 44a) or Y2). Thus, with the V block 48 brought close to the backup block 46, the relative position of the piston 44p to the cylinder body 44a due to the presence or absence of the lead component P (component body PB) between the V block 48 and the backup block 46. The position is different.

From the above, the relative position of the piston 44p to the cylinder body 44a is detected by the component sensor 54, whereby the presence or absence of the lead component P at the component supply position SS is detected. In the component sensor 54, when the pair of clamp members 45 are in the approach state in which the pair of clamp members 45 are brought close to each other by the operation of the air cylinder 41, the lead component P is present at the component supply position SS Is detected (hereinafter referred to as "no component"), and when the piston 44p is at the position Y1 (for example, not at the position Y2), the lead component P exists at the component supply position SS (hereinafter "component" Can be detected. The component sensor 54 may output an ON signal, for example, when the piston 44p is at the position Y2.

Since the lead component P is relatively large, the difference in relative position of the piston 44p to the cylinder body 44a due to the presence or absence of the component body PB of the lead component P between the pair of clamp members 45 is accurately determined by the component sensor 54 Can be detected.

The lead cutting device 20 cuts the lead L of the lead component P located at the component supply position SS although not shown, and in a state where the lead component P is clamped by the component clamping device 38, the lead L is It is cut off.

solenoid valve

64 and 66. 41 and 44 are connected. Further, the feeder side control device 60 is connected to an assembly device side control device 62 which is a control device mainly composed of a computer provided in the assembly device main body 10. The assembly apparatus side controller 62 includes an execution unit, a storage unit, an input / output unit and the like, and to the input / output unit, the substrate conveyance holding device 12, the component supply device 14, the component insertion device 16 and the like are connected. .

Supplied.

On the other hand, the tape component TP is supplied to the feeder 18 in a zigzag state, and for example, as shown in FIG. 10, is in a state of being bent at a bending line H indicated by a broken line. Then, in the taped component TP, no lead component P exists near the bending line S. If information indicating the detection result of the presence or absence of the lead component P is not supplied to the assembly apparatus side controller 62 in the feeder (including the case where the presence or absence of the lead component is not detected in the feeder), the lead component is placed at the component supply position SS. In the electronic circuit assembly apparatus, the working heads 20 and 21 are controlled, the working heads 20 and 21 are moved, the pickup operation is performed, and the insertion operation to the substrate S is performed even though P does not exist. In addition, the cycle time is adversely affected, for example, imaging and image processing are performed for each control of the work heads 20 and 21. Furthermore, although the lead component P is not held, it is determined that the lead component P is dropped, and problems such as an apparent decrease in the holding ratio (e.g., an adsorption ratio) occur. In addition, there is also a problem that a defective product which is an electronic circuit in which the lead component P is not mounted is manufactured.

Therefore, in the present embodiment, the presence or absence of the lead component P at the component supply position SS is detected by the component sensor 54, and when the detection result shows that there is no component, information representing that (hereinafter referred to Information that is output may be referred to as feeder-side information) is supplied to the electronic circuit assembly device. In addition, it is also acquired that the component is out of parts based on the detection result of the component sensor 54, and information representing that is also supplied to the electronic circuit assembly device.

In the feeder-side control device 60, a component detection program represented by the flowchart of FIG. 8 is executed. In this program, each time the feed device 36 and the component clamp device 38 are operated, that is, the taped component TP is fed by one pitch by the feed device 36 by the operation of the air cylinder 41 and the component clamp by the operation of the air cylinder 44. It is executed each time the V block 38 is brought close to the backup block 36 by the device 38.

In step 1 (hereinafter abbreviated as S1; the same applies to the other steps), the detection value of the component sensor 54 is read, and in S2, it is determined whether the detection result is "component present" or not. . If the detection result is "parts present", the number counter is cleared in S3. In this case, information indicating that the lead component P is present at the component supply position SS is not output.

On the other hand, when the detection result is "parts absent", in S4, information representing that there is no part is created and output as feeder side information. Then, at S5, the count value of the number counter for counting the number of times when the detection result is no component is incremented by one. Then, in S6, it is determined whether or not the count value of the number counter exceeds the set number, and if it is less than the set number, the process returns to S1 as it is. On the other hand, S1, 2, 4 to 6 are repeatedly executed, and when the set number of times is exceeded, it is determined that the component is out, and the determination of S6 is YES. At S7, information indicating that the component is out is created and output as feeder side information.

In the assembling apparatus side controller 62, the part insertion program represented by the flowchart of FIG. 9 is executed.
In S21, feeder-side information is acquired, and in S22, it is determined whether or not the feeder-side information is information representing a shortage of parts, and in S23, it is determined whether it is information representing no parts. If the determination results of both S22 and S23 are NO, control of the working heads 20 and 21 and the working head moving device 22 is permitted in S24. The work heads 20 and 21 are moved, and a component at the component supply position SS is picked up and inserted into the substrate S.

On the other hand, if the feeder-side information is information representing no parts, the determination in S23 is YES, and the control of the working heads 20 and 21 and the working head moving device 22 is prohibited in S25. Since no lead component P exists at the component supply position SS, there is no need to control the component insertion device 16. If the feeder-side information is information representing a component shortage, the determination in S22 is YES, and the electronic circuit assembly device is stopped in S26. Thereafter, after the taped component TP is replenished by the operator, the operation of the electronic circuit assembling apparatus is started.

As described above, in the present embodiment, the component clamp device 38 provided at the component supply position SS is provided with the component sensor 54 for detecting the presence or absence of the lead component P at the component supply position SS. Therefore, the presence or absence of the lead component P can be accurately detected by the component sensor 54. In addition, in patent document 1, there is no description regarding the detection method of the presence or absence of the lead components P in component supply position SS.

Further, information representing the presence or absence of the lead component P at the component supply position SS detected by the component sensor 54 is supplied to the electronic circuit assembly device. In the electronic circuit assembly apparatus, control of the component insertion device 16 is permitted or prohibited based on the presence or absence of the lead component P at the component supply position SS. For example, when the lead component P does not exist near the bending line of the tape Even in this case, it is possible to satisfactorily prevent the component insertion device 16 from being unnecessarily operated, and it is possible to suppress the consumption of unnecessary cycle time. In addition, it is possible to suppress a decrease in the component holding ratio due to the absence of the lead component P at the component supply position SS. Patent Document 1 does not disclose that information regarding the presence or absence of the lead component P at the component supply position SS is output to the electronic circuit assembly device.
