Abstract

PURPOSE:To make an automatic insertion of a leg of a lead component available even in the case that the leg curves by moving the leg joint of the lead component toward a connection hole of a circuit member while holding the leg joint tightly for correcting the curve of the leg and by inserting the leg into the connection hole after fitting the location of the tip of the leg to the connection hole. CONSTITUTION:If claws 5 and 6 are moved downward in the vertical direction by driving a vertical direction driving source 14 while holding legs 18 and 19 tightly, the legs 18 and 19 slide in circle holes which are made by notches 7 and 8 while the claws are closed since the diameter of the circle holes is a little bit larger than the outer diameter of the legs 18 and 19. Thus, the curve of the legs 18 and 19 is corrected. When the claws 5 and 6 are stopped a little before the tips of the legs 18 and 19, the tips of the legs 18 and 19 fit to the connection holes 21 and 22 of a socket 4. Then, when the socket 4 is moved up, the tips of the legs 18 and 19 enter the tapered sections 23 and 24 of the connection holes 21 and 22. Nextly, the claws 5 and 6 are moved back and then a lead component chuck 2 is pushed downward to insert the legs 18 and 19 into the connection holes 21 and 22 of the socket 4.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an automatic lead component insertion device for inserting the legs of a lead component such as a semiconductor element into a connection hole of a circuit member such as a socket.

<Prior Art> In a conventional insert machine that automatically inserts the legs of a lead component into a socket, the legs of the lead component must be straight and the tip pitches of the plurality of legs must be aligned at a constant value.

<Problems to be Solved by the Invention> ° However, in lead parts, the legs are straight and the tip pitch is uniform immediately after manufacture, but during processes such as inspection and transportation, the legs bend and most of the leads The parts cannot be automatically inserted by an insert machine as they are. For this reason, conventionally, it has been necessary to manually align the tip pitches of the legs prior to automatic insertion, which is a complicated task, or the insertion has been done entirely manually.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an automatic lead component insertion device that enables automatic insertion even when the legs are bent.

<Means for Solving the Problems> In order to achieve the above object, in the automatic lead component insertion device according to the present invention, the legs of the lead component supported at fixed positions corresponding to the connection holes of the circuit member can be slid. The plurality of legs are individually provided with gripping means that can be gripped and moved in a fixed direction corresponding to the connection hole, and a pushing means for pushing the lead component toward the connection hole.

Function> In the automatic lead component insertion device according to the present invention, the gripping means grips the base of the leg of the lead component and moves in the direction of the tip of the foot, that is, in the direction of the connection hole of the circuit member. With the tip position aligned with the connection hole, the lead component is pushed by the pushing means so that the foot of the lead component fits into the connection hole.

<Embodiment> FIG. 1 shows the side structure of an automatic lead component insertion device of this embodiment. In the figure, 1 is a correction chuck, 2 is a lead component chuck, 3 is a lead component, and 4 is a socket. FIG. 2 shows the planar structure of the correction chuck 1, and FIG. 3 shows the side structure. In the figure, 5 and 6 are nails, 7.
8 is a notch, 9 is a fulcrum, 10 is a spring, 11 is a wire,
12° is a wire drive source, 13 is a lateral drive source, 14 is a vertical drive source, 15.16 is a support member, and 17 is a slide member.

The orthodontic chuck 1 has two legs 18.1 of the lead part 3.
Two pieces are individually provided for 9.

The lead component chuck 2 holds the lead component 3 in a fixed position corresponding to the connection hole 21, 22 of the socket 4. As shown in FIG. 4, the lead component 3 includes a cap 20 housing a circuit element and two legs 18 and 19. The socket 4 is an object into which the lead component 3 is inserted, and includes two connection holes 21.22 into which the two legs 18.19 of the lead component 3 are fitted. The upper end of this connection hole 21.22 has a tapered portion 2 that serves as a guide when inserting the foot 18.19.
324 is formed.

The structure of the correction chuck 1 will be explained in detail with reference to FIGS. 2 and 3.

Two pawls 5.6 are attached to a fulcrum 9 at the end of the support member 15.
The two ends of each spring 10 are engaged with each other at the right end in the figure from the fulcrum 9.
Furthermore, both ends of the 7-shaped wire 11 are engaged. The claws 5, 6 are normally in an open state due to the bias of the spring 10, and are brought into a closed state by pulling the wire 11 to the right in the figure. Semicircular notches 7 and 8 are formed respectively. These semicircular notches 7 and 8 become circular when the claws 5.6 are in the closed state. At this time, the notches 7 and 8 become circular. The diameter of the circle formed by is slightly larger than the outer diameter of the legs 18.19 of the lead part 3.

A wire drive source 12 for pulling the wire 11 is disposed at the right end of the support member 15 in the drawing.

The support member 15 is connected to the support member 1 via the slide member 17.
6 so as to be movable in the left and right direction.

A lateral drive source 13 is disposed on the right side of the drawing of the support member 1, and the support member 1 is driven by the lateral drive source 13.
5 is driven in the left-right direction, and therefore the pawls 5.6 move in the left-right direction. The support member 16 is driven in the vertical direction in the figure by a vertical drive source 14 fixed to a member (not shown), so that the claws 5.6 move in the vertical direction.

The operation will be explained below based on FIG.

In FIG. 1(a), the claws 5.6 of the two correction chucks 1 are at the upper end position and the retracted position, and the lead component chuck 2 has chucked the lead component 3 at a predetermined position corresponding to the socket 4. in a state.

At this time, since the legs 18.19 of the lead component 3 are bent, the tips of the legs 18.19 are connected to the connection holes 21.1 of the socket 4.
22 does not match.

Thereafter, the support member 15 is driven by the lateral drive source 13.
The pawl 5.6 is therefore driven towards the foot 18.19 of the lead part 3. During this movement, the claws 5 and 6 are held by the spring 10.
It is in the open state due to the energization. Notch 7 of claw 5.6
．． 8 is a position near the base of the foot 18i9, that is, the nail 5
．． The lateral movement of the pawls 5, 6 ceases when the circle formed by the notch 7.8 is in a coaxial relationship with the connection hole 21.22 of the socket 4, respectively, when the latter is closed.

Thereafter, when the wire 11 is pulled by the wire drive source 12, the claws 5, 6 close against the bias of the spring 10, and in the closed state of the claws 5, 6, the circular hole formed by the notch 7.8 The base portions of the legs 18 and 19 of the lead component 3 pass through. Figure 1(b) shows this foot 18.
19 is shown gripped by the jaws 5.6 of the correction chuck 1. Even if the legs 18 and 19 are slightly bent, their bases are connected to the connection holes 21 of the socket 4.
22, and with the foot 18.19 passing through the circular hole formed by the notch 7.8 of the claw 18.19, the circular hole and the connecting hole 21.22 are approximately coaxial. .

Next, the support member 16 is driven by the vertical drive source 14.
Therefore, the pawl 5.6 is moved vertically downward. In this case, the diameter of the circular hole formed by the notch 7.8 in the closed state of the pawl 5.6 is slightly larger than the outer diameter of the foot 18.19, so that the foot 18.19 is When the claw 5.6 is moved vertically downward while holding the , the circular hole is located at the foot 18
．． Slide 19. By vertically downward movement of the claw 5.6, the bending of the foot 18.19 is corrected, and when the claw 5.6 is stopped slightly before the tip of the foot 18.19, the foot 18.
．． The tip of 19 coincides with the connection holes 21 and 22 of socket 4. After that, when the socket 4 is raised, as shown in Fig. 1 (C).
As shown in the figure, the tips of the legs 18.19 are connected to the connecting holes 21.22.
into the tapered portions 23 and 24 of.

Next, when the tension on the wire 11 by the wire drive source 12 is released, the claws 5.6 open due to the bias of the spring 10.
Furthermore, when the pawl 5.6 is moved backward by the drive of the lateral drive source 13 and the lead component chuck 2 is subsequently pushed downward, the foot 18.19 is inserted into the connection hole of the socket 4, as shown in FIG. 1Td). It is inserted at 21°22.

In the above operating procedure, the foot 18.19 is inserted into the connection hole 21.22 after the claw 5.6 is opened, but in order to increase the reliability of the operation, the foot 18.19 is inserted into the connection hole 21.22 by the claws 5 and 6. The lead part 3 may be pushed down to a certain extent while holding the tip of the lead part 3, and then the claw 5.6 may be released and the lead part 3 may be pushed down to the final position.

<Effects of the Invention> As explained above, in the present invention, the gripping means grips the base of the leg of the lead component and moves in the direction of the connection hole of the circuit member, thereby correcting the bending of the leg.
Since the leg is inserted into the connection hole after the position of the tip of the leg is aligned with the connection hole using the gripping means, even if the leg of the lead component is slightly bent, the lead component can be inserted into the connection hole reliably. This enables automatic insertion of lead components into sockets, etc. Therefore, it is possible to improve work efficiency and reduce product costs by eliminating the conventional complicated manual work.
