Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a jig for aligning and supporting a large number of integrated circuit components when soldering them to a lead frame.

[Technical background of the invention and its problems]

The applicant of the present invention first provided a jig 1 that can align and support a large number of integrated circuit components W when soldering them to a lead frame l of an integrated circuit component W, as shown in FIG. Along with this part W
A method is proposed in which the jig 1 is inserted between the support rods 2 and 3 of the jig 1 from the package.

That is, the lead frame 1 protruding downward from the component W is slid at each part until the integrated circuit component W reaches the jig 1 via the guide body 4 from the package W. This is because it is common sense to place the jig 1 on the stand 5 used during insertion in the same posture as when used during soldering.
In order to project the lead frame l downward from the lower support rod 2, the lead frame l is inevitably attached to the component W.
This was common sense since it was located on the underside of the main body, but it had a drawback. For example, as shown in Figure 2,
Inside the jig 1, a guide body 7 having a stepped portion 6 that can be adapted to various dimensions and a lifting prevention body 8 are provided along the support bars 2 and 3, and when a part W is inserted between the support bars 2 and 3, Since this is a method of inserting the part W using the two support rods 2 or the guide body 7 as a guide,
It is difficult to maintain the posture of the component W, and due to variations in the length and spacing of the lead frame l, etc.
If this lead frame l comes off the step 6 of the guide body 7 and the main body of the component W comes off from the top of the support rod 2, or if the component W in the package cage is placed with the lead frame l on the lower side, Because the lead frame l is unevenly tilted to either the left or right side, when the part W is transferred from the package cage to the jig 1 via the guide 4, the lead frame l on the sliding side
There was also a risk that the parts W would come off or stop on the way, and the delivery would not go smoothly. For this reason, the size of the component W is limited to one type, or strict dimensional control is required.

[Purpose of invention]

An object of the present invention is to provide a jig that allows the backside sliding of the main body of an integrated circuit component, which is effective in preventing the component from coming off the support rod when the integrated circuit component is inserted into the jig. .

[Structure of the idea]

The invented jig consists of a frame body that is attached to a conveyor holder on a soldering line, and a plurality of fixedly installed sets that span between this frame body and press down on the upper side of the main body of the integrated circuit component. an upper support rod; and a plurality of lower support rods arranged parallel to the lower part of each set of upper support rods and having one end attached to the frame so as to support the lower side of the main body of the integrated circuit component. , a gate body that supports the other end of each set of lower support rods and is movable up and down with respect to the frame body, and a component insertion port that is opened in the frame body and faces the gate body. It is characterized by this.

[Example of idea]

Hereinafter, the present invention will be explained in detail with reference to an embodiment shown in FIGS. 3 to 12.

As shown in FIGS. 3 and 4, the jig 11
1 is a titanium frame 13 that is attached to a conveyor holder 12 of a soldering line from above, and this frame 1.
A steel wire 14 made of a tungsten round bar serves as a set of two upper support rods that are fixedly provided in plural sets and span between 3 and hold down the upper side of the main body of an integrated circuit component (hereinafter referred to as IC) W; Two tungsten circles as lower support rods are arranged parallel to the lower part of each set of upper steel wires 14 and have one end attached to the frame 13 to support the lower surface of the main body of the ICW. A gate body 1 supports the steel wire 15 of the bar and the other end of each set of lower steel wires 15 and is movable up and down with respect to the frame 13.
6, and an IC insertion port 17 as a component insertion port opened in the frame body 13 opposite to the gate body 16. The transport holder 12 is pulled by a pin 19 protruding from a chain 18 on one side, and moves along the automatic soldering line along guide rails 20 on both sides.

As shown in FIG. 5, the gate body 16 of the jig 11
are grooves 23 cut out on both sides of the frame 13.
A tension spring 26 is engaged between the L-shaped fittings 24 fixed to both ends of the gate body 16 and the bent portion 25 of the frame body 13, and the springs 26 on both sides The gate body 16 is pulled in a direction to close the IC insertion port 17. In addition, the above-mentioned bending part 2
5 is partially cut out so that the L-shaped fitting 24 can be seen, as shown in FIG.

Also, in this Fig. 5, 27 is a tilting table;
A lever 28 for fixing the jig 11 placed in the opposite direction is rotatably provided on the tilting table 27 by a shaft 29. It is pressed against the bent part 25 and fixed, and the gate body 16 is pushed up and each
Air cylinders 33 that open the IC insertion port 17 are fixed on both sides, and a piston rod 34 of the air cylinder 33 is opposed to the tip 35 of the L-shaped fitting 24. The tilting table 27 also has a gripping portion 36 of the jig 11.
An elongated hole 37 into which the is inserted is bored.

Further, as shown in FIGS. 6 and 7, the tilting table 27 is rotatably supported on the upper end of the column 41, and is rotated by a rotary actuator 42, and the stoppers 43, 44 On the right side of this tilting table 27, there is a
A package fixing part 48 is provided which holds a large number of tube-shaped IC package P (shown in FIG. 9) in multiple rows by a pair of support stands 45 and a pair of presser bars 47 pulled down by a spring 46. Further, on the left side of this tilting table 27, a guide body 50 and a floating prevention body 51 are supported by a pair of supports 49, and a jig 11 is fixed continuously thereto as shown in FIG. A jig fixing part 52 is provided.
In addition to the lever 28 and the air cylinder 33, the jig fixing part 52 includes positioning parts 53, 5.
4 and a floating prevention book 56 rotatably supported by a shaft 55. 57 and 58 are IC locking means for inserting the ICW in the package P into the jig 11 in two steps.

Then, as shown in FIG.
In between, in order to insert the ICW in the opposite direction as shown in Fig. 8, the IC package P is placed in the above-mentioned support with the ICW lead frame l facing upward, as shown in Fig. 9. 45, and push up the gate body 16 with the piston rod 34 of the air cylinder 33 as shown in FIG.
When the IC insertion slot 17 is opened and the tilting table 27 is tilted from the upper left position to the lower left position, the ICW will slide inside the package P with the back a of the main body.
Further, it slides on the guide body 50 as shown in FIG. 11, enters the frame 13 through the IC insertion port 17, and slides on the upper steel wire 14 as shown in FIG. 12.

When this jig 11 is removed from the tilting table 27, the gate body 16 is completely fitted into the groove 23 by the spring 26, and each IC insertion port 17 is closed.

[Effect of idea]

According to the present invention, the upper support rod is fixedly provided,
Since the jig has a structure in which the lower support rod is movable together with the gate body, when inserting integrated circuit components into this jig, the jig is turned upside down along with the package cage that continuously stores the integrated circuit components. It is possible to slide the integrated circuit component on the back side of the main body of the component by setting the integrated circuit component in the orientation, and the sliding of the component can be performed stably and smoothly over the entire back surface of the main body of the component. For example, even if there are variations in the length and spacing of the lead frames of parts, parts of various sizes can be slid smoothly regardless of this, and the back of the main body of the part can be stabilized by the fixed support rod. Since the parts can be supported on the support rod, they will not come off.
