Description

Wire clamp device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire clamp device, and in particular, a movable clamp tip is configured to be provided with an extrusion force by a coil body which moves left and right by Fleming's left hand law.

In general, the wire clamp device is a device for clamping the supply of the wire provided to the filter at the time of wire bonding, the exact clamp time and pressure is a factor to maintain the quality of the wire bonding. As an example of such a clamp device, the voice coil motor 12 and the fixed clamp plate 13 are fixed to the fixed bracket 11 and the movable side arm 15 of the voice coil motor 12 is fixed as in the first diagram. ) One end is fixed, the movable side arm 15, the center portion is coupled to the hinge 16, and the other end of the movable side arm 15 is a movable clamp plate 17 abutting the fixed clamp plate 13 is fixed.

This is because when the movable portion 14 of the voice coil motor 12 rises, for example, the movable clamp plate 17 rotates counterclockwise about the hinge 15 to decrease the pressure with the fixed clamp plate 13. Let's do it. On the contrary, when the movable portion 14 is lowered, the movable clamp plate 17 also rotates clockwise around the hinge 16 so that the movable clamp plate 17 and the fixed clamp plate 13 come into close contact with each other to perform the clamping function. Make it.

However, such a structure has a problem in that the configuration is complicated and the size is turned on, takes up a lot of space for practical use, and it is difficult to provide accurate clamping force.

For this purpose, a clamp method disclosed in Korean Patent Publication No. 94-742 has been proposed, which has a pair of fixed shaft arms 3 and a movable side arm 2 for clamping the wire 4 as shown in FIG. The arm 2 is supported by a plate spring-shaped support point 2-1 and configured to be bent by the piezoelectric element 1, and further includes a plane 2a for clamping the wire 4 of the movable shaft arm 2. Is formed so as to oppose the plane 3a of the fixed side arm 3 at a predetermined angle when not clamping, and the movable side arm 2 is bent by the piezoelectric element 1 when clamping. 3) and a pair of clamp surfaces 2a and 3a are formed so that the hinge plane 2a of the movable side arm 2 clamps the wire 4 in parallel.

In this method, it is difficult to accurately realize the tension of the movable arm 2 at the support point 2-1, and it is necessary to control the mutual organic tension between the piezoelectric element 1 and the movable arm 2, but the adjustment value is different depending on the material. There is a different problem.

The present invention is to solve this problem, it characterized in that the wire clamp method to perform the clamp function by the coil body to move left and right by the Fleming's left hand law.

That is, in the wire clamp device, the movable clamp tip corresponding to the fixed clamp tip fixed to the fixed clamp plate is made to move integrally with the coil body moving horizontally by the left hand rule of Fleming to fix the wire.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

3 is an exploded perspective view of the present invention, in the wire clamp device for clamping the wire by the movable clamp plate having the movable clamp tip and the fixed clamp plate having the fixed clamp tip, the fixed clamp tip fixed to the fixed clamp plate 20 The movable clamp tip 22 corresponding to (21) is made to move integrally with the coil body 23 which is horizontally moved by Fleming's left hand law to fix the wire.

According to claim 1, wherein the fixed clamping 21, one horizontal axis 24 is fixed to the diameter portion between the movable shaft tip 22 is positioned between the horizontal axis 24, the movable clamp tip 22 is a horizontal axis ( It is configured to receive the clamp pressure by the coil body 23 adhered to the 24.

The coil body 23 corresponding to the horizontal shaft 24 forms a horizontal shaft 24 insertion guide groove 25, and the horizontal shaft 24 has a movable clamp tip 22 between the movable clamp tip 22 and the coil body 23. An elastic spring 26 is fitted to the 22 to provide elastic force.

The coil body 23 is made to implement the Fleming's left-hand law to move horizontally by the yoke 28 in which the permanent magnet 27 is embedded.

The yoke 28 is coupled to the fixing member 29 is coupled to the fixed clamp plate 20 to maintain a constant horizontal interval, and the yoke 28 horizontal position is adjusted by the combined screw 30 Is made possible.

4 is a longitudinal cross-sectional view of the yoke 28 used in the present invention. The permanent magnet 27 is fixed to the coaxial protrusion 28-1 of the cylindrical yoke 28 having one end closed, and the screw 30 at the center of the bottom end. ) The coupling screw hole 28-2 is formed.

According to the present invention configured as described above, the fixed clamp plate 20 and the fixing member 29 shown in FIG. 3 are fixed to each other so as to be horizontal to each other, and the permanent magnets 27 are provided at the protrusions 28-1 of the yoke 28. ),

Of course, the fixed clamp tip 21 is fixed between the horizontal shafts 24, the movable clamp tip 22 is inserted therein, the elastic spring 26 is inserted, and the horizontal shaft 24 is inserted into the guide groove 25 of the coil body 23. ) Is inserted. The fixed clamp plate 20 and the fixing member 29 are coupled to each other by sandwiching the coil body 23 sandwiched between the outer wall of the yoke 28 and the permanent magnet 27. In this state, the coil body 23 receives the initial elasticity force into the yoke 28 by the single spring 26. In such an initial state, when the wire 4 is inserted between the coarse clamp tip 21 and the movable clamp tip 22 and a current is applied to the coil body 23 by a controller (not shown) during wire bonding, the flaming is performed. The coil body 23 is selectively moved to the left and right according to the left-hand law of the movable clamp tip 22. Accordingly, the movable clamp tip 22 receives the force through the coil body 23 and the elastic spring 26 to the fixed clamp tip 21. This facilitates the clamping function of the wire.

At this time, the initial state of the coil body 23 is changed according to the position of the yoke 28, the position of the yoke 28 by adjusting the distance to the fixing member 29 by turning the screw 30 of the coil body 23 The position can be adjusted conveniently.

As described above, according to the present invention, the coil body driven by the left hand law of Fleming pushes and pulls the movable clamp tip so that the wire passing through the fixed clamp tip and the movable clamp tip can be easily clamped.
