Steps # 41 to # 46 are a first transfer step of receiving one axial electronic component from the component supply position P of the component supply means 4 and sending it to a position opposite to the component delivery position Q, and step # 51.
The steps # 55 to # 55 are the second transfer step of transferring the axial electronic components sent to the position opposite the component delivery position Q to the component delivery means 12 waiting at the component delivery position Q.

The first transfer step and the second transfer step are carried out in parallel by the component transfer means 7. And these 1st and 2nd transfer processes mean the component transfer processes which transfer an axial electronic component from the component supply position P to the component delivery position Q one by one. Although not shown in FIG. 11, the component supply step 4 is responsible for the component supply step of sequentially guiding the axial electronic components in the state shown in FIG. 7 to the component supply position P.

Steps # 61 to # 65 are tacts executed by the component delivery means 12 and are so-called component delivery steps. Further, steps # 31 to # 35 are tact executed by the component inserting means 11, which is a so-called component inserting step.

Next, the operation of each part of the apparatus in each processing step will be described. In the state shown in FIG. 6, the component transfer means 7 is in a position where the transfer chuck 6a faces the component supply position P and in which the transfer chuck 6b faces the component delivery position Q. In this state, the tact of the component transfer means 7 is started, and the transfer chuck 6a moves to steps # 41 to # 4.
6, and the transfer chuck 6b is responsible for the second transfer process shown in steps # 51 to # 55.

The first transfer step is the first step # 41.
Then, the transfer chuck 6a is moved forward to the component supply position P as shown by an arrow X in FIG. And the next step #
42, the holding projections 19b.
19c holds the tapes 3a and 3b of the axial type electronic component 1. Then, in the next step # 43, the transfer chuck 6a holds the tapes 3a and 3b and moves along the line X in FIG.
By moving backward in the direction, the leading axial electronic component 1 of the component supply means 4 is pulled out by the distance d1 of the component arrangement shown in FIG. Then, in the next step # 44, the tapes 3a, 3 from which the cutters 5a, 5b have been pulled out.
By cutting b, as shown in FIG. 8, the axial type electronic component 1 separated from the subsequent is obtained. At this time, the transfer chuck 6a is separated from the leading axial electronic component 1
By holding the front ends of the tapes 3a and 3b on both ends of
It holds one axial electronic component 1.

In step # 51 which is executed in parallel with step # 41, the transfer chuck 6b holds one axial electronic component 1 by holding one end of the tapes 3a, 3b, and the axial electronic component 1 is held. While holding the component 1, the component 1 is moved down to the component delivery position Q as shown by an arrow Y in FIG. In the subsequent step # 52, the opposite ends of the tapes 3a and 3b held by the transfer chuck 6b are attached to the delivery chuck 9a for the 26 mm component of the component delivery means 12.
It is held by 9b and the axial electronic component 1 is delivered to the component delivery means 12. In the following step # 53, the transfer chuck 6b moves upward along the arrow Y and returns to the original position. Then, the next step # 54 is step #
It is the same operation as 45. That is, steps # 45, 54
Is the step # 4 until the controller 18 just before that.
After confirming the end of 4 and 53, the AC servo motor 8 is operated to move the rotary table 7a to 90 degrees as indicated by an arrow R.
This is the process of rotating by °. By these steps # 45 and 54, the transfer chuck 6d is moved to a position facing the component supply position P, and at the same time, the transfer chuck 6a that has undergone the first transfer process is rotationally moved to the position opposed to the component delivery position Q. To do.

Thereafter, as shown in steps # 46 and 55, the first transfer step and the second transfer step executed by the component transfer means 7 are performed.
The transfer process of (1) waits for timing. This timing waiting is a process of stopping the operation until the end of step # 64 in the component delivery process executed by the component delivery means 12. By this timing waiting process, the component transfer process of one axial electronic component in the component transfer means 7 is completed. Hereinafter, similar processing is repeated.

In the component delivery means 12, the process starts in step # 61 in which the axial electronic component 1 is received from the component transfer means 7 in response to the operation of the component transfer means 7 in step # 52. In step # 61, the delivery chucks 9a, 9b for 26 mm parts hold the tapes 3a, 3b to receive the axial electronic parts 1. In the following step # 62, the sliders 23 and 24 move together on the guide 28 to the component insertion means 11 side via the power unit 36 and the power transmission mechanism 29 shown in FIG. Moving. Then, the following step # 63
As shown in, the delivery chucks 9a and 9b that have reached the component insertion position K deliver the held axial electronic component 1 to the component insertion means 11. Then, the next step # 64
Then, the sliders 23 and 24 are returned to their original positions on the guide 28.

In the next step # 65, the taping width d2 of the axial type electronic component 1 to be inserted into the circuit board is 26 m.
m is not performed during the normal work, and the delivery chuck that waits at the component delivery position Q is set only when the taping width d2 of the axial electronic component 1 mounted on the substrate becomes 52 mm.
This is performed in order to change the delivery chucks 9a and 9b for mm components to the delivery chucks 10a and 10b for 52 mm components.

In the component inserting means 11, the component delivering means 12
Step # 31 for receiving the axial electronic component 1 from
To start the process. Then, in the next step # 32,
As shown in FIG. 12, the axial type electronic component 1 held by the component inserting means 11 is cut into a length W including the electronic component body 1a and the lead wires 2a and 2b having a predetermined length, and at the same time, W is cut. Both ends of the lead wires 2a, 2b included in the length of the
Bend it into an L shape corresponding to the position. Then, in the next step # 33, the lead wires 2a and 2b bent in the L shape are formed.
To the component mounting holes 17a, 17b of the circuit board 17
Then, in the next step # 34, as shown in FIG. 13, the ends of the lead wires 2a and 2b inserted into the component mounting holes 17a and 17b are bent, and the axial electronic component 1 is mounted on the circuit board 17. Fix it. Then step #
As shown in 35, after waiting for the timing for a predetermined time, the process returns to step # 31 to repeat the series of processes.
The timing wait shown in # 35 is a process of stopping the operation for an appropriate time so that step # 62 of the part delivery means 12 and step # 31 are synchronized.

Next, the case of inserting and mounting the 52 mm axial type electronic component in the circuit board 17 will be described. 5
In the case of inserting and mounting the 2 mm axial type electronic component 1, each transfer chuck 6a mounted on the component transfer means 7 is
6b, 6c and 6d hold the axial electronic component 1 by holding the tapes 3a and 3b of the axial electronic component 1 using the holding projections 19a and 19d equipped for 52 mm components. Except for this point, as in the case of the 26 mm component, a series of component transfer steps are repeated by the processing procedure shown in steps # 41 to # 46 and steps # 51 to # 55 in FIG.

The part delivery means 12 is different from the case of processing a 26 mm part in that step # 65 shown in FIG. 11 is carried out. Step # 65 is shown in FIG. 9 in the initial state.
26 mm waiting at the parts delivery position Q as shown in (a)
The delivery chucks 9a and 9b for the parts are connected to the air supply port 37.
The operation of the piston 25 operated by the first slider 23
Is moved to a position retracted from the parts delivery position Q. As a result, at the component delivery position Q, only the delivery chucks 10a and 10b for 52 mm components are in a standby state. As shown in FIG. 9B, except for performing step # 65 in which the delivery chucks 9a and 9b for 26 mm parts are moved to positions retracted from the part delivery position Q, the process for 26 mm parts is performed thereafter. It is similar to the case.

[0021]

However, as described above, the delivery chucks 9a and 9b for the 26 mm parts and the delivery chucks 5
In the conventional electronic component insertion method and apparatus in which the delivery chucks 10a and 10b for 2 mm parts are provided on the dedicated sliders 23 and 24 respectively, and the positions of the delivery chucks used are switched by the relative movement of the sliders 23 and 24, There is a problem that the structure is complicated and the device cost is increased due to the equipment such as a guide for movably guiding the sliders 23 and 24.

Further, the sliders 23, 24 that move relative to each other
Are vertically displaced from each other so that they can move in the direction of the rotation axis of the rotary table 7a. However, since the two sliders 23 and 24 are vertically overlapped, as shown in FIG. There has been a problem that the height h of the part becomes large, which causes the device to become large and heavy.

Further, in order to make the apparatus compact and the like, as shown in FIG. 14, the upper surface of the lower first slider 23 is brought close to the outer circumference of the turning radius of the turntable 7a. Then, when the rotary table 7a is rotated by 90 °, the transfer chucks 6a, 6b, 6c and 6d are rotated.
A range R in which the upper second slider 24 interferes with the second slider 24 is generated. Therefore, conventionally, the rotary table 7a is rotated after step # 62 in which the second slider 24 is moved to the component inserting means 11 side in order for the component delivering means 12 to deliver the axial electronic component 1 to the component inserting means 11. By synchronizing the operation timings of the component transfer means 7 and the component delivery means 12 so that steps # 45 and 54 are performed, the second slider 24 is out of the interference range when the rotary table 7a is rotated. The transfer chucks 6a, 6b, 6c, 6d and the second slider 24 are prevented from interfering with each other. However, in such a measure, when the synchronization is deviated due to a power failure during the operation, an operation trouble of the controller 18, or the like, the transfer chucks 6a, 6b, 6c, 6d collide with the first slider 23, There is a possibility that a serious trouble such as breakage of expensive parts may occur.

The present invention has been made in view of the above circumstances, and by reducing the number of sliders and guides equipped, the structure of the component delivery means can be simplified and the manufacturing cost of the electronic component insertion device can be reduced. Further, by reducing the height of the slider portion of the component delivery means, it is possible to prevent the apparatus from becoming large and heavy, and at the same time, the component transfer means and the component delivery means may be separated due to a power failure during operation, a controller operation trouble, or the like. It is an object of the present invention to provide a highly reliable electronic component insertion method and device which are free from damage due to interference even when operations are out of synchronization with each other.
