Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic connector insertion device that automatically inserts a :T connector into a predetermined insertion hole of a board such as a printed circuit board.

The connectors are approximately as shown in Figure 1 (at, (b), (cl)
It is a small electronic component with a shape as shown in the figure, and the main body (1) and the top (1) are mounted on legs 2.3 (a plurality of legs are provided).The number of legs 2 and 3 is often from 2 to 10. It will be done.

Yes, there are different sizes of margins in the width direction.

In order to schematically show the direction 5- of one leg 2 and 3 of the connector in a plane perpendicular to each other, the state shown in Fig. 1 (el) is shown in Fig. 1 (
It will be indicated by a symbol such as di. That is, the longitudinal direction is shown by two parallel sides, and the difference in one width direction is shown by the long side and short side. Note that the direction in which the short side is located in the width direction will be referred to as the orientation 5 of the connector 4.Electronic components inserted and mounted on the printed circuit board 6 are mounted in various orientations, and connectors can also be mounted in the 2nd direction. As shown in the figure, it can be mounted in various orientations, such as 4X with an X orientation, 4X' with an X orientation, 4Y with a Y orientation, and 4Y' with a Y' orientation.

Conventionally, connectors were inserted into printed circuit boards manually, but the work speed had to be changed because the connectors were small and difficult to handle, and it was difficult to distinguish the orientation before inserting them. A method has been used that is slow and has a risk of inserting the wire in the wrong direction, resulting in extremely poor workability and reliability. Also, automatic insertion has been attempted, but no one has been found that is fast, highly workable, and highly reliable.

The inventors have conducted repeated research in order to solve the above-mentioned conventional problems, and the present invention was made based on the findings obtained during the research.

The present invention selectively transfers the connectors, which have been conveyed in a fixed orientation by the transfer section, to +90f or -90f at the delivery section.
After rotating it by 0 degrees, it is delivered to the insertion part, and in the insertion part, it is selectively rotated by 0 degrees (that is, not rotated) or rotated by 90 degrees on one side, and then inserted into the board.
The purpose of the present invention is to provide an automatic connector insertion device that easily and reliably inserts and mounts connectors in any direction of , Y, or Y, and has high speed, high workability, high reliability, and excellent performance. That is.

The present invention includes a connector transfer section, a delivery section, and an insertion section, and the connector transferred by the transfer section while oriented in a fixed direction is rotated at a rotation angle of +90 at the transfer section.
[or select either -90 degrees and rotate it, then deliver it to the insertion section, and in the insertion section, select either 0 degrees or one side @eoH as the rotation angle and rotate the delivered connector This is an automatic connector insertion device specially designed to insert the connector into the board after it has been inserted into the board.

The present invention will be explained with reference to the drawings and embodiments.

In the plan view of FIG. 3, numeral 7 indicates a connector supply section, and numeral 8 indicates a connector supply section.

8B, 8G, 8D, 8E are 9 stations that supply different types of connectors, 9B, 9G.

This is a feeder that supplies one feeder to each of 9D and 9K in a predetermined and constant orientation. For the purpose of simplifying the explanation of the concept, we will briefly discuss the differences between the types of connectors. 1O is the movement path of the holding mechanism through which the holding mechanisms of the connectors provided on the counting side (24 in the figure) are provided in the transfer section, and is a circumference centered on the 01 center jl, which moves in the direction of the O1 arrow 12. The holding mechanism moves intermittently along the passage at pitches (1/24 of a circumference in the figure).

13 is a rotating station, 14 is a delivery station, 1
5 is the return rotation stake 3. A delivery section 16 is provided including these three stations. 17 is the insertion portion and t)%18 is the insertion position.

19 is a printed circuit board, indicated by X in the diagram.

It can move in any direction in the horizontal plane in the x', y, and y' directions.

Regarding the direction of rotation, for convenience of explanation, in this specification, the clockwise direction is described as positive and the counterclockwise direction is described as negative, but the counterclockwise direction may also be described as positive.

9 people at each supply station 19 B * 9 C * 9
In D*9E, the signals are supplied in a predetermined order by a program or manual operation. At this time, the orientation of connector 4 is
It is supplied circumferentially oriented in the direction of travel of arrow 12. The connector 4 that has moved along the moving path IO is rotated at the rotation station 13 with an axis perpendicular to the xllly axis (
2 axes) by +90 degrees or -90f. In FIG. 3, the connectors 4 at the rotation station 13 have been rotated -90 degrees to point radially outward, and the connectors 4 at the transfer station 1 have been rotated -90 degrees to face radially outward.
It is rotated 90 degrees and faces radially inward (Y direction).

At the transfer station 14 the connectors 4 are identical 9. - It is delivered to the insertion section 17 while maintaining the same orientation. In this case, the connector 4 is inserted in the Y direction, so the insertion part 17
Now, without rotation (rotation angle 0 degrees), print circuit board 1.
Insert into 9.

At the PL rotation station 15, the holding claw of the connector rotated at the rotation station 13 is rotated so as to return it to its original orientation.

Figure 4 (a) for cases requiring insertion in other orientations.
I (b) I (C) I will explain in (d).

FIG. 3(a) shows the same process as FIG. 3. Same figure ←)
indicates that the insertion position 18 is rotated by +90 degrees at the rotation station 13 to make it in the X direction, and the insertion portion 17 is further rotated by -90 degrees as a piece 1190gIL. In the same figure (C), in order to make it in the T direction, the rotation station 13 is set to 190 tls, and the insertion part 17 is set to 0
degree rotation (ie, no rotation). The same figure (d
) indicates that the rotating stake 13 is rotated by -90 if, and the insertion portion 17 is rotated by -90 to make it in the X direction. +9 as 90 degrees on one side in insertion section 17
A structure such as 011 =IO- may also be used.

! By rotating, the insertion portion 17 has a rotation range of up to 90 degrees. If the rotation operation is performed only by the insertion part 17, the direction x,
Since x', y, and y' are arbitrarily selected, the rotation range is 27
011 and has a complicated structure.
7, it is difficult to configure such a wide range of rotation. In contrast, in the present invention, by dividing the rotation operation into two, the rotation angle at the insertion part 17 is small, the structure is simple, and the operation is simple and fast. Since the OT4 can be carried out in accordance with instructions or instructions by manual operation, it is possible to perform automatic insertion of a connector at high speed, with high workability and with high reliability.

This will be explained with reference to FIG.

A frame 65 is fixed to the arm portion 22 (FIG. 5). Reference numeral 66 denotes an elevating frame, which is supported along guide rails 67 of the frame 65 so as to be movable up and down.

On the other hand, a main shaft 68 is rotatably supported on the frame 65, and is driven by a belt 69 to operate the rod 2 via the cam 7G and the bell crank 71 to move the elevating frame 66.
is now going up and down. Further, the elevating frame 66 is always subjected to upward force by a spring 73. -19- A sleeve 76 is rotatably supported on the elevating frame 66 via bushes 74 and 75. A holding claw opening/closing mechanism 77 for opening and closing the holding claws 34 is attached to the lower end of the sleeve 76, and together with the sleeve 76, forms a rotating part.

A pinion 78 is fixed to the sleeve 76, and a cover 79
The rack 80 is engaged with a rack 80 that slides back and forth in the horizontal direction. The two hooks 80 are always subjected to a force directed to the left in FIG. 12 by the spring 81. One end of the rack 80 forms an L-shaped arm 82 with a diameter of φ.

Reference numeral 83 denotes an arm that is swingably supported by a rotation of a pin 84 fixed to the frame 65, and is designed to swing by a cam 85 provided on the main shaft 68. A spring 86 provides a force that constantly presses the cam roller 87 against the cam 85. The arm 83 is integrally formed with an arm 89 rotatably provided with a bell crank 88 at its tip. The bell crank 11 88 has a roller 90 at one end that pushes the arm 82.

10G, the tip of the push rod 36 is connected to the main body IK of the connector 4.
This is a relief groove for the legs 2 to escape from.

It is also possible to make the groove shallow and apply it to the tip of the leg 2 to prevent it from touching the main body 1. In this case, it is better to provide a stopper for the leg 2 in the groove.

In action-)! To explain, the transfer machine $33 holds the transferred connector 4 on the leg 2 with the holding claw 34, and
After receiving the wave, the main shaft is rotated, and the lifting frame 66 is lowered by the action of the cam 70, and the connector 4 is brought closer to the printed circuit board 19. In this case, the arm 89 is also rotated by the action of the cam 85. However, if it is not necessary to change the orientation of the connector 4, if the cylinder 91 is tightened, the roller 90 will be in the retracted state and will not touch the opening arm 582 and will not move the rack 80, so the sleeve 76 will not rotate. The orientation of connector 4 does not change.

The legs 3 of the connector 4 are attached to the printed circuit board 19 by the holding claws 34.
At the lower end of the push rod 36,
bury # on the top surface of the connector 4 and hold down the center, and then bend the connector 4 from the back side of the printed circuit board 19 by activating the mechanism 38 and bending a predetermined one of the legs 3 to prevent the connector 4 from being pulled out.
is fixed to the printed circuit board 19, and then the elevating frame 66 is raised to return to the original state.

If it is necessary to rotate the connector 4, hold the cylinder 91 in an extended state, and when the arm 89 swings due to the action of the cam 850, the roller 90 will push the arm 82 and move the rack 80, causing the sleeve 76 to move. It can be rotated to change the direction of the connector 4 by 90 degrees.

-22- As the supply section, a conveyor, chute, transfer robot, etc. may be used instead of the pipe rating feeder.The transfer section is not limited to circular motion, and has a non-circular movement path such as a chain: Iy conveyor. There is no difference between 4 and 4 things. The connector holding mechanism is not limited to the rotary rack/binion type, but may also be a cam/link type, a lever/strike type, or the like.

In the above explanation, the two axes are explained as vertical directions, but
It may be in other directions.

The above explanation uses the Hiro connector as an example, but the present invention generally refers to electronic components with directional shape such as a connector trimmer, or electrolytic capacitors.]:0,)
The present invention can also be applied to the case of inserting a polar directional electronic component such as a transistor, and such a case is also included in the present invention.

Note that if the insertion part is rotated by selecting an angle a that satisfies 190 degrees≦α≦+90 degrees, the insertion part can be inserted in any direction.

The present invention is based on IIl Kla shown in the above example.
23-, but also covers various embodiments based on the same idea.

The present invention comprises a connector transfer section, a delivery section, and an insertion section, and the connector, which is oriented in a certain direction and transferred by the transfer section in good condition, is rotated by +90 degrees at the pinching section. The connector is rotated by selecting either -90 degrees or -90 degrees, and then delivered to the insertion section, where the delivered connector is rotated by selecting either 0 degrees or 90 degrees on one side as the rotation angle. By inserting the connector into the board after it has been inserted, the work can be done smoothly and easily when inserting the connector in the correct direction on the printed board. It is possible to provide an automatic connector insertion device that is highly workable and highly reliable, and has extremely great practical effects.
