[0006]
Each of the transfer chucks 6 a, 6 b, 6 c, 6 d is provided with a holding groove 15 to hold the tapes 3 a, 3 b of the axial type electronic component 1. 19c and 19d, which are attached to the periphery of the rotary table 7a at intervals of 90 ° by attachment portions 20a, 20b, 20c and 20d. Further, each of the transfer chucks 6a, 6b, 6c, and 6d is advanced and retracted in the radial direction of the rotary table 7a by slide support portions 21a, 21b, 21c, and 21d that support the mounting portions 20a, 20b, 20c, and 20d ( Move back and forth).
[0007]
As shown in FIG. 6, the component delivery unit 12 receives the axial electronic component 1 moved to the component delivery position Q by the component transfer unit 7 and delivers it to the component insertion unit 11.
As shown in FIGS. 9A and 9B, the component delivery means 12 includes a pair of delivery chucks 9a and 9b for holding a tape portion of an axial electronic component having a taping width d2 (see FIG. 7) of 26 mm. , A second slider 24 having a pair of delivery chucks 10a and 10b for holding a tape portion of an axial type electronic component having a taping width d2 of 52 mm, and a first slider 23 The piston 25 and the tension spring 26 for switching the position to the parts delivery position Q, the guide 27 for supporting the first slider 23 so as to be movable in the position switching direction, and the axial electronic parts 1 received at the parts delivery position Q The first slider 23 and the second slider 24 together with the component delivery position Q and the component insertion position.

[0008]
Although the detailed description is omitted, the component insertion means 11 stands by at the component insertion position K. When the axial electronic component 1 is received from the component delivery means 12, the component insertion on the circuit board positioned below the component insertion means 11 is performed. The lead wires 2a and 2b at both ends of the axial electronic component 1 are inserted and mounted in the holes.
[0009]
Next, a component mounting process performed by the electronic component insertion apparatus 200 will be described with reference to FIG.
First, an explanation will be given of the insertion mounting process of an axial electronic component having a taping width d2 of 26 mm.
In FIG. 11, steps # 41 to # 46 and steps # 51 to # 55 are tacts executed by the component transfer means 7.
Steps # 41 to # 46 are a first transfer process in which one axial electronic component is received from the component supply position P of the component supply means 4 and sent to a position opposite to the component delivery position Q. Steps # 51 to # 55 are steps. This is a second transfer step of transferring the axial electronic component sent to the position opposite to the component delivery position Q to the component delivery means 12 waiting at the component delivery position Q.
[0010]
The first transfer process and the second transfer process are performed in parallel by the component transfer means 7. And these 1st and 2nd transfer processes mean the component transfer process which transfers an axial type electronic component one by one from the component supply position P to the component delivery position Q.
Although not shown in FIG. 11, the component supply unit 4 takes charge of the component supply process of sequentially guiding the axial electronic components in the state shown in FIG. 7 to the component supply position P.
[0011]
Steps # 61 to # 65 are tacts executed by the component delivery means 12, which is a so-called component delivery process.
Steps # 31 to # 35 are tacts executed by the component insertion means 11, and are so-called component insertion steps.
[0012]
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 6 a faces the component supply position P, and the transfer chuck 6 b faces the component delivery position Q.
In this state, the tact of the component transfer means 7 is started, the transfer chuck 6a is responsible for the first transfer process shown in steps # 41 to # 46, and the transfer chuck 6b is shown in steps # 51 to # 55. Responsible for the second transfer process.
[0013]
In the first transfer process, the transfer chuck 6a moves forward to the component supply position P as shown by an arrow X in FIG. In the next step # 42, the holding protrusion 19b. 19c holds the tapes 3a and 3b of the axial type electronic component 1.
In the next step # 43, the transfer chuck 6a moves backward in the X direction of FIG. 6 while holding the tapes 3a and 3b, so that the parts are arranged by the arrangement interval d1 of the parts shown in FIG. The leading axial electronic component 1 of the supply means 4 is pulled out.
Then, in the next step # 44, the tapes 3a and 3b from which the cutters 5a and 5b are drawn are cut to obtain the axial type electronic component 1 cut off from the subsequent portion as shown in FIG. At this time, the transfer chuck 6 a holds one axial electronic component 1 by holding the front end sides of the tapes 3 a and 3 b at both ends of the separated first axial electronic component 1.
[0014]
In step # 51 executed in parallel with step # 41, the transfer chuck 6b holds one axial type electronic component 1 by holding one end of the tapes 3a, 3b, and the axial type electronic component 1 is removed. With the held state, as shown by an arrow Y in FIG.
In the subsequent step # 52, the opposite end portions of the tapes 3a, 3b held by the transfer chuck 6b are held by the delivery chucks 9a, 9b for the 26 mm parts of the parts delivery means 12, and the axial electronic component 1 is moved. Delivered to the parts delivery means 12.
In subsequent step # 53, the transfer chuck 6b moves upward along the arrow Y and returns to the original position. The next step # 54 is the same operation as step # 45. That is, in steps # 45 and 54, the controller 18 confirms the end of each step # 44 and 53 immediately before it, operates the AC servo motor 8, and moves the rotary table 7a to 90 as shown by the arrow R. This is a rotation process.
By these steps # 45 and 54, the transfer chuck 6d moves to a position facing the component supply position P, and at the same time, the transfer chuck 6a that has completed the first transfer process rotates and moves to a position opposite to the component delivery position Q. To do.
[0015]
Thereafter, as shown in steps # 46 and # 55, the first transfer process and the second transfer process executed by the component transfer means 7 wait for timing. This waiting for timing 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 type electronic component in the component transfer means 7 is completed. Thereafter, the same processing is repeated.
[0016]
The component delivery unit 12 starts processing at step # 61 in which the axial electronic component 1 is received from the component transfer unit 7 in response to the operation of the component transfer unit 7 at step # 52.
In Step # 61, the delivery chucks 9a and 9b for 26 mm parts hold the tapes 3a and 3b to receive the axial electronic parts 1.
In the subsequent step # 62, the sliders 23 and 24 move together on the guide 28 toward the component insertion means 11 via the power unit 36 and the power transmission mechanism 29 shown in FIG. Moving.
Then, as shown in the subsequent step # 63, the delivery chucks 9 a and 9 b that have reached the component insertion position K deliver the held axial type electronic component 1 to the component insertion means 11. Then, in the next step # 64, the sliders 23 and 24 are returned to their original positions on the guide 28.
[0017]
The next step # 65 is not performed in the normal operation when the taping width d2 of the axial type electronic component 1 to be inserted into the circuit board is 26 mm, but when the taping width d2 of the axial type electronic component 1 to be mounted on the board is 52 mm. Only the delivery chuck waiting at the parts delivery position Q is changed from the delivery chucks 9a, 9b for 26 mm parts to the delivery chucks 10a, 10b for 52 mm parts.
[0018]
The component insertion unit 11 starts the process at step # 31 in which the axial electronic component 1 is received from the component delivery unit 12.
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 replaced with an electronic component main body 1a and lead wires 2a and 2b having a predetermined length. At the same time, both ends of the lead wires 2a and 2b included in the length of W are bent into an L shape corresponding to the positions of the component mounting holes 17a and 17b of the circuit board 17. In the next step # 33, the leading ends of the lead wires 2a and 2b bent in an L shape are inserted into the component mounting holes 17a and 17b of the circuit board 17, and in the next step # 34, as shown in FIG. In addition, the end portions of the lead wires 2 a and 2 b inserted into the component mounting holes 17 a and 17 b are bent to fix the axial electronic component 1 to the circuit board 17. Next, as shown in step # 35, after waiting for a predetermined time, the process returns to step # 31 to repeat a series of processes.
The timing waiting shown in # 35 is a process of appropriately stopping the operation for a time so that the step # 62 of the parts delivery means 12 and the step # 31 are synchronized.
[0019]
Next, the case where 52 mm axial type electronic components are inserted and mounted on the circuit board 17 will be described.
In the case of the 52 mm axial type electronic component 1 insertion and mounting process, the transfer chucks 6a, 6b, 6c, 6d provided in the component transfer means 7 have gripping protrusions 19a, 19d provided for the 52mm component. The axial type electronic component 1 is held by holding the tapes 3 a and 3 b of the axial type electronic component 1.
Except for this point, as in the case of the 26 mm component, a series of component transfer steps are repeated in the processing procedure shown in steps # 41 to # 46 and steps # 51 to # 55 in FIG.
[0020]
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 performed.
In step # 65, as shown in FIG. 9A, in the initial state, the delivery chucks 9a and 9b for 26 mm parts that stand by at the parts delivery position Q are operated by the piston 25 that operates at the air supply port 37. The slider 23 is moved and retracted to a position retracted from the component delivery position Q. As a result, at the parts delivery position Q, only the 52 mm parts delivery chucks 10a and 10b are in a standby state.
As shown in FIG. 9 (b), the 26 mm parts are processed except that step # 65 is performed to place the 26 mm parts delivery chucks 9a and 9b in the retracted positions from the parts delivery position Q. It is the same as the case of doing.
[0021]
[Problems to be solved by the invention]
However, as described above, the delivery chucks 9a and 9b for 26mm parts and the delivery chucks 10a and 10b for 52mm parts are mounted on the dedicated sliders 23 and 24, respectively, and the sliders 23 and 24 are moved relative to each other. In the conventional electronic component insertion method and apparatus for switching the position of the delivery chuck to be used, the structure is complicated and the apparatus cost is increased due to the provision of a guide or the like for movably guiding the sliders 23 and 24. There was a problem.
[0022]
Further, the sliders 23 and 24 that move relative to each other are shifted in the vertical direction 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 overlap each other, they are shown in FIG. As described above, the height dimension h of the slider portion of the component delivery means 12 is increased, and there is a problem that the apparatus is increased in size and weight.
[0023]
Further, in order to make the device compact, etc., as shown in FIG. 14, if the configuration is such that the upper surface of the first slider 23 located on the lower side approaches the outer periphery of the rotation radius of the rotary table 7a, When the table 7a is turned by 90 °, a range R in which the transfer chucks 6a, 6b, 6c, 6d interfere with the second slider 24 on the upper side is generated.
Therefore, conventionally, after the step # 62 in which the second slider 24 moves to the component insertion means 11 side in order for the component delivery means 12 to pass the axial electronic component 1 to the component insertion means 11, the rotary table 7a is rotated. 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 area when the rotary table 7a is rotated. Thus, interference between the transfer chucks 6a, 6b, 6c, 6d and the second slider 24 is prevented.
However, in such a response, the transfer chucks 6a, 6b, 6c, 6d and the first slider 23 collide with each other when the synchronization is lost due to a power failure during the operation or an operation trouble of the controller 18, etc. There is also a risk that serious troubles such as breakage of expensive parts may occur.
[0024]
The present invention has been made in view of the above circumstances, and can reduce the manufacturing cost of the electronic component insertion device by simplifying the configuration of the component delivery means by reducing the number of sliders and guides provided. Reduction of the height of the slider part of the delivery means prevents the equipment from becoming larger and heavier, and at the same time operates between the parts transfer means and the parts delivery means due to a power failure in the middle of the operation or operation trouble of the controller. It is an object of the present invention to provide a highly reliable electronic component insertion method and apparatus that does not cause damage due to interference even when the synchronization is lost.

This is achieved by an electronic component insertion device characterized by switching a delivery chuck used for delivery of an axial type electronic component.
[0027]
According to the method and apparatus configuration described above, the plurality of sets of delivery chucks are mounted on a single chuck support block while being shifted in position along the rotation axis direction of the rotary table, and the axial type electronic components to be handled are handled. The set of delivery chucks to be used is switched by the operation of moving the chuck support block along the rotation axis direction of the rotary table so that the delivery chuck corresponding to the taping width is positioned at the component delivery position Q.
Therefore, as compared with the conventional method and apparatus for individually moving the individual delivery chuck pairs themselves along the rotation axis direction of the rotary table, the sliders and guides necessary for the slide operation for positioning the delivery chuck at the component delivery position Q are compared. The number of equipment can be reduced, and a plurality of sets of delivery chucks can be arranged at the same height with respect to the rotation center of the rotary table, and the height dimension can be reduced.

The position switching means for positioning the delivery chuck pair to be used at the parts delivery position Q by moving forward and backward, and the delivery for transferring the axial type electronic parts to the parts insertion means by moving the chuck support block forward and backward on the slider A configuration including a driving unit is preferable.
In this way, the movement stroke by the position switching means corresponds to the amount of displacement between each delivery chuck pair along the axial direction of the rotary table, and the movement stroke by the delivery drive means is between the parts delivery position Q and the parts insertion means. It is only necessary to correspond to the distance between them, and the operation of each moving operation unit becomes simple and clear.
[0029]
Still preferably, in the electronic component insertion device, the position switching means may be configured to displace the slider itself by displacing a piston coupled to the slider with fluid pressure.
If it does in this way, it will become possible to ensure an arbitrary sliding amount easily by the design change of the dimension of the cylinder which accommodates a piston, and control of the amount of fluid to supply.

[0031]
The electronic component insertion apparatus 100 according to this embodiment includes a component supply unit that sequentially guides the axial type electronic component 1 having both ends of the pair of lead wires 2a and 2b held by the tapes 3a and 3b to the component supply position P. 4, the component transfer means 7 for moving the axial electronic component 1 supplied to the component supply position P to the component delivery position Q at a position shifted by a predetermined angle from the component supply position P, and the component delivery position Q A component delivery means 41 that passes the axial electronic component 1 to the component insertion means 11 that waits for the axial type electronic component 1 that has moved to the part insertion position K, and an axial type electronic that is delivered from the component delivery means 41 at the component insertion position K. Component insertion means 11 for inserting and mounting the component 1 in the component insertion hole of the circuit board positioned at a fixed position, and each of the above-mentioned means 4, 7, 41, 11 is defined as a prescribed timing. In that actuating the axial type electronic component 1, which is supplied to the component supply position P, it is configured to insert mounted on the circuit board being positioned in place.
[0032]
The electronic component insertion apparatus 100 according to this embodiment is obtained by replacing the component delivery means 12 of the conventional electronic component insertion apparatus 200 shown in FIG. 6 with a component delivery means 41, and each means 4 other than the component delivery means 41. , 7, 11 are the same as those of the prior art, and the description of the same means as those of the prior art is omitted or simplified.
[0033]
That is, the component transfer means 7 is mounted on the rotary table 7a that can be rotated by a predetermined angle within a plane including the component supply position P and the peripheral edge of the rotary table 7a so as to be able to advance and retreat in the radial direction of the rotary table 7a. And a transfer chuck 6a, 6b, 6c, 6d for holding the tapes 3a, 3b at both ends of the mold electronic component 1.

[0034]
Further, the component insertion means 11 moves the axial electronic component 1 delivered from the component delivery means 41 at the component insertion position K onto the circuit board positioned at a fixed position, as shown in FIG. The pair of lead wires 2a and 2b of the axial electronic component 1 are inserted and mounted in the component insertion holes.
[0035]
The component delivery means 41 of the present embodiment grips the tapes 3a, 3b at both ends of the axial electronic component 1 that has moved to the component delivery position Q with a delivery chuck, and this delivery chuck is in the direction of the rotation axis of the rotary table 7a. The basic function of passing the axial type electronic component 1 to the component insertion means 11 that stands by at the component insertion position K by moving it along a predetermined distance is common to the conventional one.
[0036]
The component delivery means 41 of this embodiment also includes two sets of delivery chucks 42a, 42b, 43a, 43b in order to grip the tapes 3a, 3b at both ends of the axial type electronic component 1.
The delivery chucks 42a and 42b are for gripping the tapes 3a and 3b when the width dimension (taping width d2) between the tapes 3a and 3b of the axial electronic component 1 is 26 mm. On the other hand, the delivery chucks 43a and 43b are for holding the tapes 3a and 3b when the taping width d2 of the axial electronic component 1 is 52 mm.
[0037]
However, the parts delivery means 41 of this embodiment is improved for the simplification of the configuration and the reduction of the height dimension, and the delivery chucks 42a, 42b, 43a, 43b of each set are different for each set. The rotary table 7a is mounted on a single chuck support block 45 with its position being offset along the rotational axis direction.

The delivery chucks 42a, 42b, 43a, 43b used for the above are switched.
[0038]
As shown in FIGS. 2A and 2B, the block moving mechanism 47 rotates the rotary table 7a with a slider 51 itself that supports the chuck support block 45 so as to be movable along the rotational axis direction of the rotary table 7a. A position switching means 53 for positioning the delivery chuck pair to be used at the parts delivery position Q by moving forward and backward by an offset amount (K) between each delivery chuck pair along the axial direction, and chuck support on the slider 51 A delivery driving means 55 is provided for delivering the axial electronic component 1 to the component insertion means 11 by moving the block 45 forward and backward.
[0039]
The position switching means 53 is configured to displace the slider 51 itself by displacing the piston 62 coupled to the slider 51 via the connecting rod 61 with the fluid pressure supplied to the fluid pressure supply ports 63a and 63b of the cylinder 63. It is.
The position switching means 53 controls the ON / OFF control of the fluid pressure supply to the ports 63a and 63b, so that the delivery chucks 42a and 42b for 26 mm parts are moved to the parts delivery position as shown in FIG. The position is switched to either the state positioned at Q or the state where the delivery chucks 43a and 43b for 52 mm parts are positioned at the part delivery position Q as shown in FIG.

In the present embodiment, two sets of delivery chucks are provided for 26 mm parts and 52 mm parts. However, there are three types of taping widths of the axial type electronic parts 1 to be handled. When three sets are installed, the position switching means 53 needs to be configured to switch the position of the piston 62 to the three positions.
FIGS. 3A and 3B show an example of the configuration of the position switching means 53 for such three-position switching.
The position switching means 53 shown here has three fluid pressure supply ports (1) to (3) in the cylinder 63 as shown in FIG. 3 (a), as shown in FIG. 3 (b). Further, the position of the piston 62 is switched to the three positions A, B, and C shown in FIG. 3A by turning on and off the fluid pressure supply to each port.
[0041]
As shown in FIG. 4, the delivery driving means 55 uses the driving force of the driving rod 71 driven forward and backward in the direction orthogonal to the slider 51 as the driving force along the extending direction of the slider 51 via the link mechanism 73. And is transmitted to the chuck support block 45, and the chuck support block 45 is advanced and retracted on the slider 51.
[0042]
The electronic component insertion apparatus 100 described above includes a component supply step of sequentially guiding the axial type electronic component 1 in a state where both ends of the pair of lead wires 2a and 2b are held by the tapes 3a and 3b to the component supply position P. The component type transfer step of moving the axial electronic component 1 supplied to the supply position P to the component delivery position Q at a position deviated from the component supply position P by the predetermined angle, and moved to the component delivery position Q. A component delivery process for passing the axial electronic component 1 to the component insertion means 11 waiting for the axial electronic component 1 at the component insertion position K, and the component insertion means 11 to which the axial electronic component 1 is passed are positioned at a fixed position. Axial-type electronic part supplied to the component supply position P by carrying out each step of the component insertion step of inserting and mounting into the component insertion hole of the circuit board being mounted at a specified timing 1, it is inserted and mounted to the circuit board being positioned in place.
[0043]
The electronic component insertion method realized by the electronic component insertion apparatus 100 according to the present embodiment is characterized by the fact that when the taping width of the axial electronic component 1 to be processed is changed in the component delivery step, the chuck is changed accordingly. The point is that the delivery chuck used for delivery of the axial electronic component 1 is switched by a movement operation of the support block 45 along the rotational axis direction of the rotary table 7a.
Except for switching the position of the delivery chuck to be used, the basic processing procedure of each of the above steps is the same as the procedure shown in FIG.
[0044]
In the electronic component insertion method performed by the electronic component insertion apparatus 100 described above, a plurality of sets of delivery chucks 42a, 42b, 43a, 43b are shifted in position along the rotational axis direction of the rotary table 7a to form a single chuck support block 45. A chuck support block along the rotation axis direction of the rotary table 7a so that the delivery chucks 42a, 42b, 43a, 43b according to the taping width of the axial type electronic component 1 to be handled are positioned at the parts delivery position Q. The set of delivery chucks 42a, 42b, 43a, 43b to be used is switched by 45 moving operations.
[0045]
Therefore, the delivery chucks 42a, 42b, 43a, 43b are compared with the conventional method and apparatus for individually moving the pair of delivery chucks 42a, 42b, 43a, 43b along the rotational axis direction of the rotary table 7a. The number of sliders 51 and guides required for the slide operation for positioning to the delivery position Q can be reduced, and the configuration of the component delivery means 41 is simplified by reducing the number of sliders 51 and guides, and the electronic component insertion device 100 The manufacturing cost can be reduced.
[0046]
Furthermore, when compared with the conventional method and apparatus in which the individual delivery chucks 42a, 42b, 43a, 43b pairs themselves are individually moved along the rotational axis direction of the rotary table 7a, a plurality of delivery chucks 42a, 42b, 43a, 43b can be arranged at the same height with respect to the rotation center of the turntable 7a, the height dimension can be reduced, and the size of the apparatus can be increased by reducing the height dimension of the slider 51 portion of the component delivery means 41. And weight can be prevented.
[0047]
Further, as shown in FIG. 5, the height dimension of the slider 51 portion of the component delivery means 41 is reduced by positioning the chuck support block 45 within the rotation range of the transfer chucks 6a, 6b, 6c, 6d on the rotary table 7a. Thus, it is also useful to avoid obstructing the rotation, and thereby synchronization of the operation between the component transfer means 7 and the component delivery means 41 due to a power failure in the middle of operation or an operation trouble of the controller. Even when they deviate from each other, damage due to interference does not occur, and the operation reliability for the electronic component insertion process can be improved.
[0048]
Further, in the present embodiment, the block moving mechanism 47 moves the slider 51 itself, which supports the chuck support block 45 so as to be movable along the rotational axis direction of the rotary table 7a, to advance and retract along the rotational axis direction of the rotary table 7a. As a result, the position switching means 53 for positioning the pair of delivery chucks 42a, 42b, 43a, 43b to be used at the parts delivery position Q and the chuck support block 45 on the slider 51 are moved forward and backward to move the axial type electronic component 1. Is provided with a delivery drive means 55 for delivering the product to the component insertion means 11.
Therefore, the movement stroke by the position switching means 53 is made to correspond to the amount of displacement between each delivery chuck 42a, 42b, 43a, 43b pair along the axial direction of the rotary table 7a, and the movement stroke by the delivery drive means 55 is the component delivery position. The distance between the Q and the component insertion means 11 may be set appropriately, and the operation of each moving operation unit becomes clear and the control of the drive unit can be facilitated.
[0049]
Further, in the present embodiment, the position switching means 53 is configured to displace the slider 51 itself by displacing the piston 62 coupled to the slider 51 with fluid pressure. Therefore, it becomes possible to easily secure an arbitrary slide amount by changing the design of the cylinder accommodating the piston 62 and controlling the amount of fluid to be supplied, and the delivery chucks 42a, 42b, 43a, It becomes easy to set the shift amount between the positions of the 43b pairs.
[0050]
In the present invention, when the taping width of the axial type electronic component to be handled is three kinds, the position switching means 53 shown in FIG. 3 may be used.
When the taping width is more than four types, a feed mechanism using a known stepping motor or the like is used instead of the position switching means 53, or a moving stroke for position switching is provided to the delivery drive means 55. This can be dealt with by including.
[0051]
【The invention's effect】
In the electronic component insertion method and apparatus of the present invention, the plurality of sets of delivery chucks are mounted on a single chuck support block while being shifted in position along the rotational axis direction of the rotary table, and the taping width of the axial type electronic component to be handled The set of delivery chucks to be used is switched by the operation of moving the chuck support block along the rotation axis direction of the rotary table so that the delivery chuck corresponding to the position of the delivery chuck is located at the component delivery position Q.
Therefore, as compared with the conventional method and apparatus for individually moving the individual delivery chuck pairs themselves along the rotation axis direction of the rotary table, the sliders and guides necessary for the slide operation for positioning the delivery chuck at the component delivery position Q are compared. The number of equipment can be reduced, and the construction of the component delivery means can be simplified by reducing the number of equipment of the slider and guide, thereby reducing the manufacturing cost of the electronic component insertion device.
[0052]
Further, in comparison with the conventional method and apparatus for individually moving individual delivery chuck pairs themselves along the rotation axis direction of the rotary table, a plurality of sets of delivery chucks are arranged at the same height with respect to the rotation center of the rotary table. Therefore, the height dimension can be reduced, and the size and weight of the apparatus can be prevented from being increased by reducing the height dimension of the slider portion of the component delivery means.
In addition, the reduction in the height dimension of the slider portion of the part delivery means also helps to prevent the slider from being positioned in the rotation range of the transfer chuck on the rotary table. Even when the operation is out of synchronization between the component transfer means and the component delivery means due to operation trouble of the controller, damage due to interference does not occur, and the operation reliability for the electronic component insertion processing can be improved.
[0053]
According to the third aspect of the present invention, the movement stroke by the position switching means corresponds to the amount of displacement between each delivery chuck pair along the axial direction of the rotary table, and the movement stroke by the delivery drive means is the part delivery position. The distance between the Q and the component insertion means may be set according to the distance, and the operation of each moving operation unit becomes simple and clear, and the control of the drive unit can be facilitated.
[0054]
Furthermore, if it is set as the structure of Claim 4, it will become possible to ensure an arbitrary slide amount easily by the design change of the dimension of the cylinder which accommodates a piston, and control of the fluid quantity to supply, in component delivery means It is easy to set the shift amount between the delivery chuck pair.
