Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a chuck device for an electronic component that chucks the lead portions at both ends of an electronic component, which has lead portions extending on both sides of a main body portion. .

[Prior Art] In order to perform processing such as winding on an electronic component having lead portions extending from both ends of a main body portion, it is necessary to chuck the electronic component lead portion in a rotatable manner. Here, if the lead part is rigid, a means configured to clamp the lead part can be used as the means for performing the chuck described above, but if the lead part is a flexible member that is easily bent, If such a lead portion is formed, the workpiece will become unstable during machining simply by holding the lead portion, and accurate machining of the workpiece will not be possible.

Therefore, in order to stabilize the workpiece, a chuck means has been conventionally used which includes an insertion hole into which the lead part is inserted and a locking member which locks the lead part inserted into the insertion hole. Are known.

[Problems to be Solved by the Invention] Here, if the lead portion of the work described above is a flexible member, it may already be in a bent state when it is carried into the chuck device.
Further, since the lead portion is stabilized by being inserted into the insertion portion of the chuck means, it is preferable that the diameter of the insertion hole is not more than twice the wire diameter of the lead portion. Moreover, due to the trend of miniaturization of electronic components in recent years, for example, 0.2
Some workpieces have lead parts with ultrafine wire diameters of mm or less. Inserting a workpiece with a lead made of ultra-fine and flexible wire into a narrow-diameter insertion hole is extremely troublesome and difficult to automate; This was done manually by a person, and there were disadvantages such as the inability to speed up the work.

Therefore, the applicant of the present application has proposed a chuck device that allows even a soft lead portion with a small wire diameter to be inserted into the insertion hole of the chuck means at high speed and easily. This chuck consists of a pair of clamping plates placed inside a pair of chuck members each having an insertion hole for inserting the lead part of the workpiece, and guides the lead part of the workpiece by a certain amount toward the chuck member side. When the chuck member and the work clamping member are movable in the direction toward and away from each other, and the chuck member is moved a predetermined amount in the direction toward each other. In addition, the chuck member and the workpiece holding member are configured to be moved in conjunction with each other.

Although this configuration has the advantage that even if the lead part has a small wire diameter and is easily bent, it can be inserted reliably into the insertion hole of the chuck member. However, this does not mean that there are no problems.

That is, predetermined processing and processing operations such as winding are performed on the workpiece while it is chucked by the chuck member.In order to perform such operations smoothly, the main body of the workpiece must be chucked by the chuck member. However, with the above-mentioned configuration, the workpiece may become misaligned when being transferred to the workpiece holding member. In some cases, it was not possible to adjust the position of the workpiece during the check.

The present invention was developed in view of the above points, and its purpose is to adjust the position of the main body of the work so that it is at a constant position when the work is chucked by the chuck member. An object of the present invention is to provide a check device for electronic components that can perform the following operations.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention is provided with an insertion hole into which the lead part of an electronic component is inserted, which is formed by extending lead parts on both sides of the main body part, a pair of left and right chuck members that are movable reciprocally in directions approaching and away from the chuck members; and a pair of left and right chuck members disposed inside each of the chuck members and positioned so that the lead portion of the workpiece is led out by a certain amount toward the chuck member side. a workpiece clamping member having a pair of upper and lower clamping plates; and a workpiece clamping member that normally biases the workpiece clamping members so that a predetermined distance is maintained between them, and moves the chuck members in a direction in which they approach each other. interlocking means for guiding the two workpiece holding members so that they interlock and move in a direction in which they approach each other from a mid-stroke position to a position where they abut the end surface of the main body of the electronic component; is provided with an interlocking start position setting member that starts interlocking movement of the workpiece holding members after the portions of the lead portions led out from the workpiece holding members are inserted into the insertion holes of the chuck members; Both workpiece holding members are machined to adjust the distance between the surfaces of each holding plate that face both end surfaces of the main body of the electronic component and the surfaces that face each of the chuck members relative to the lead portion of the electronic component. The feature is that it has a configuration that includes a spacing holding mechanism that allows the spacing to be spaced apart by the distance necessary to perform the above operations.

[Operation] A workpiece holding member is installed on the workpiece by an appropriate transfer means, but the workpiece may be deviated in the axial direction when the workpiece is installed.
However, when the chuck members are moved a predetermined amount in a direction approaching each other and the workpiece clamping member moves in conjunction, the lead portion of the workpiece enters the insertion hole in the chuck member, but the chuck member and the workpiece clamping member During the movement of the workpiece, the holding plate piece on one side comes into contact with the end surface of the main body of the workpiece, thereby pushing and displacing the workpiece in the axial direction.
At the end position of the movement stroke of the workpiece holding member, both ends of the main body of the workpiece are sandwiched between the holding plate pieces on both sides, so that the workpiece is accurately positioned at this position.

[Example] Hereinafter, an example of the present invention will be described in detail based on the drawings.

First, FIG. 1 shows the overall structure of the chuck device. In the figure, 1 indicates a workpiece, and this workpiece 1 has lead parts 1b and 1 at both ends of the main body part 1a.
The workpiece 1 is supported by the workpiece holding member 10.

The workpiece holding member 10 is configured to support the lead portions 1b, 1b on both sides of the workpiece 1 by holding them from above and below.For this purpose, a pair of left and right workpiece receiving plates are used as workpiece holding plate pieces. 11, 11 and work holding plates 12, 12
and has. This workpiece receiving plate 11 is fixedly provided on a slide block 14 that can be moved toward and away from each other along a guide rod 13, and the workpiece holding plate 12 is rotatable in the vertical direction on the slide block 14. is supported by
Here, the workpiece holding plate 12 is disposed on the inside, and as shown in FIG. 2, a distance d is provided between the workpiece holding plate 12 and the workpiece receiving plate 11. There is. In this embodiment, in order to maintain this distance d, a spacer member 17 is interposed between the workpiece holding plate 12 and the workpiece receiving plate 11 as a distance adjustment mechanism. . Here, the interval adjustment mechanism is for providing a predetermined interval between the inner surface of the workpiece holding plate 12 and the outer surface of the workpiece receiving plate 11.

The workpiece receiving plate 11 also has a V-groove 11 on the top thereof for positioning the lead portion 1b of the workpiece 1.
A is formed at the bottom of the work holding plate 12, and a V groove 12a opposite to the V groove 11a is formed at the bottom of the V groove 12a, as shown in FIG. square groove 1 towards the top.
2b are arranged in series. The square groove 12b is the workpiece 1
The lead portion 1b has a width slightly larger than the diameter of the lead portion 1b, and when the lead portion 1b is held between the workpiece receiving plate 11 and the workpiece holding plate 12, the lead portion 1b enters into this square groove 12b. It's becoming like that.

Slide blocks 14, 1 to which these workpiece receiving plates 11 and workpiece holding plates 12 are attached
4 are normally placed at positions separated from each other by a predetermined distance by the action of a spring 15,
The distance between the slide blocks 14, 14 is determined according to the total length of the workpiece 1, and is maintained at a distance that allows the tip of the lead portion 1b of the workpiece 1 to be slightly guided outside. It is becoming more and more like this. The length of the lead portion 1b extending outward is determined depending on the bending strength of the lead portion 1b.If the lead portion 1b has a relatively high strength, it may be led out for a certain length; for example, it may be extremely thin. In cases where a wire rod having a flexible wire diameter is used, this lead-out length also needs to be shortened.

Next, chuck members 20, 20 are provided on the outside of the workpiece holding member 10, and each chuck member 20 is attached to an arm 21, and each arm 21 is driven by an appropriate driving means (not shown). ), it is possible to reciprocate in the directions of approaching and separating from each other. Here, the chuck member 20 is a substantially cylindrical member having a notch 22 in its circumferential body, and as is clear from FIG. One end of the insertion hole 23 is connected to a funnel-shaped lead-in part 24 formed at the tip of the chuck member 20, and the rear end opens into the notch 22. And on arm 21,
A locking member 25 is rotatably attached,
When the lead portion 1b of the workpiece 1 is inserted into the insertion hole 23 and its tip is led out to the notch 22, the locking member 25 rotates to lock the lead portion 1.
The structure is such that the workpiece 1 can be fixed by pressing b from above.

Furthermore, each workpiece holding member 10 has a rod 16 protruding from the side facing the arm 21 on which the chuck member 20 is attached, so that when the arms 21 move toward each other to a predetermined position,
The arm 21 comes into contact with the rod 16, and thereafter the chuck member 20 and the workpiece holding member 10 move in conjunction with each other while maintaining a constant distance. Therefore, the slide block 14, the guide rod 13, and the return spring 15 constitute interlocking means. Further, this rod 16 functions as an interlocking start position setting member for setting a start position for interlocking movement of the workpiece holding member 10 from a position midway through the movement stroke of the chuck member 20. However, this interlocking start position setting member is not limited to this rod 16, and the point is that the work holding member 10 can be moved from a predetermined position in the movement stroke of the chuck member 20 by following it. Bye. At the end position of the movement stroke of the work holding member 10 by the rod 16, the work holding plates 12 on both sides are brought into contact with the end surface position of the main body 1a of the work 1, as shown in FIG. It is composed of

This embodiment is constructed as described above, and its operation will be explained next.

First, the work holding plate 12 of the work holding member 10 is rotated so as to be separated from the work receiving plate 11, and in this state, the work 1 is mounted on the work holding member 10 using an appropriate means. The workpiece 1 is attached to the workpiece holding member 10.
The lead portion 1b is formed on the workpiece receiving plate 11.
This is done by positioning it within the groove 11a. Here, the lead portion 1b is easily bent, and may be bent in any direction before being attached to the workpiece holding member 10.
However, since the upper end of the V-groove 11a of the workpiece receiving plate 11 is wide, even if the lead portion 1b is slightly bent, it is extremely difficult to position it within the V-groove 11a. Never.

In this way, the lead part 1 in the workpiece 1
When the leads 1b and 1b are located in each V-groove 11a of the workpiece receiving plate 11, the workpiece holding plate 12 is rotated, and the lead portion 1b located in the V-groove 11a is pushed into the groove bottom. As a result, as shown in FIG.
and the V-groove 12a of the work holding plate 12, and the lead portion 1b enters the square groove 12b of the work holding plate 12. As a result, the lead portion 1b of the workpiece 1 faces the insertion hole 23 of the chuck member 20, as shown in FIG. At this time, the lead portion 1b is in a state of being slightly led out, and the leading portion of the lead portion 1b is positioned at a fixed position, and its bending strength is also significantly improved.

Therefore, when each arm 21 facing each workpiece holding member 10 is actuated and these arms 21 are moved in a direction approaching each other, the lead portion 1b
is guided into the insertion hole 23 via a lead-in portion 24 formed in the chuck member 20. However, as described above, the lead portion 1b is guided outward only to the extent that it can be seen slightly, and therefore the bending strength of this portion is high. Even if it collides with the wall surface or the like, it will not be bent and will be guided smoothly into the insertion hole 23. Note that at this time, the locking member 25 is connected to the chuck member 2.
It is maintained in a state where it is spaced apart from the notch 22 of 0.

After the arm 21 moves in this manner and the lead portion 1b is reliably introduced into the insertion hole 23,
The arm 21 comes into contact with the rod 16 provided on the slide block 14, and thereafter, as the arm 21 moves, the arm 21 and the workpiece holding member 10 maintain a constant distance from each other. , the slide blocks 14 are moved toward each other against the spring 15. Therefore, the workpiece holding member 10 of the lead portion 1b
The lead portion 1b is inserted into the insertion hole 23 while maintaining a constant distance between the lead portion 1b and the insertion hole 23, and the lead portion 1b is inserted into the insertion hole 23 while maintaining the above-mentioned bending strength. An insertion is made into the This lead portion 1b has a notch 2.
When the workpiece is inserted to position 2, the workpiece holding member 1
0 and the chuck member 20 stop, and the locking member 25
rotates and comes into contact with the lead part 1b,
The lead portion 1b is held between the locking member 25 and the notch 22 in a sandwiched state. At the same time, when the workpiece holding member 10 is detached from the lead part 1b, the lead part 1b of the workpiece 1 is inserted into the insertion hole 23 of the chuck member 20 by a predetermined length, as shown in FIG. , it becomes possible to check to a stable state.

The workpiece 1 supported by the chuck member 20 as described above is subjected to processing such as winding. However, since the workpiece 1 is chucked in an extremely stable state, the above-mentioned processing and processing are performed. You will be able to do it accurately and smoothly.

The workpiece 1 is mounted on the workpiece receiving plate 11 using an appropriate pick-and-place device (not shown), and the workpiece 1 is mounted on the workpiece receiving plate 11 and the workpiece holding plate 12. Although the lead portion 1b is positioned by the action of the V-grooves 11a and 12a when it is held between the main body portion 1a, the main body portion 1a may be misaligned in its axial direction. If the main body portion 1a is chucked in such a misaligned state, it will not be possible to smoothly process and process the winding wire, etc.

However, when the workpiece 1 is placed on the workpiece receiving plate 11 in a state where the workpiece 1 is displaced in the axial direction, together with the chuck member 20,
When the workpiece holding members 10 move toward each other, as shown in FIG. 6, one of the workpiece holding plates 12 comes into contact with the end surface of the main body 1a of the workpiece 1, and the workpiece 1 is held in the same position as shown in FIG. push it in the direction indicated by the arrow. At the end position of the movement stroke of the work holding member 10, the work holding plates 12 on both sides come into contact with both ends of the main body 1a of the work 1, as shown in FIG. It becomes possible to adjust the position of the work 1 in the axial direction.

Here, the work holding plate 12 and the work receiving plate 11
Since the distance d is formed between the workpiece 1 and the lead part 1b of the workpiece 1, for example, if the lead part 1b of the workpiece 1 is bent, the workpiece holding plate 12 cannot be accurately moved at the movement stroke end position of the workpiece holding member example described above. In some cases, it may not be possible to make contact with the end surface of the main body portion 1a of the workpiece 1. However, the work holding plate 1
2 is formed with a square groove 12b, and the lead portion 1b is inserted into the square groove 12b, so that the bending of the lead portion 1b can be corrected. Furthermore, at the aforementioned movement stroke end position, the workpiece holding plate 12 is reliably brought into contact with the end surface of the main body portion 1a.

As a result of the above, a certain distance is formed between the contact portion of the work holding plate 12 to the end surface of the main body portion 1a and the contact surface of the work receiving plate 11 to the chuck member 20. Therefore, if the workpiece 1 is released from being held by the workpiece holding member 10 in this state, the chuck member 2
A certain distance is ensured between the end face of lead part 0 and the end face of main body part 1a of workpiece 1, and when performing processing such as winding wire on workpiece 1, the length of winding around lead part 1b is kept constant. Machining accuracy and stability can be obtained.

On the other hand, after performing specific processing, machining, etc. with the workpiece 1 checked as described above,
To attach and detach the workpiece 1 from the chuck member 20,
What is necessary is to displace the arms 21, 21 in a direction in which they are separated from each other.

[Effects of the invention] As described in detail above, according to the invention, the workpiece holding member is moved in conjunction with the chuck member in the middle of its movement stroke while maintaining a predetermined interval by the interval holding mechanism. When the workpiece holding members are closest to each other, the electronic component is positioned in the axial direction by making contact with the end surface of the main body of the electronic component, so even if the wire diameter of the lead part is small, Moreover, even if the object is easily bent, it can be inserted into the insertion hole of the chuck member reliably, and the main body can be chucked with the position adjusted to ensure that it is in a fixed position. It has various effects such as being able to.
