[Industrial use]

The present invention relates to a universal adjusting rod capable of torsion control, and more particularly, to a universal adjusting rod capable of controlling torsion while easily adjusting the variable resistance value of high-tech equipment or various instruments that need to be adjusted with delicate force in the assembly line of electronic products. It is about.

[Private Technology]

Generally, a variable resistor is installed in an electronic product to adjust minute characteristic values, but adjustment of the variable resistor is inevitable.

1 (a) and (b) show a regulator for adjusting the variable resistance as described above, illustrating two types of regulators.

Firstly, the regulator A includes a main shaft 5 formed with a cross adjusting rod 1 for rotating an adjusting screw of a resistor mounted on a substrate, a connecting portion 3 through which the adjusting rod 1 can be exchanged and inserted therein, and the main shaft. A motor part 7 for height adjustment while rotating (5), an elastic member 9 configured above the motor part 7 to prevent breakage of resistance when the adjustment rod 1 is misplaced, and this elastic member ( 9) and the housing 11 having the motor unit 7 therein.

The regulator A inserts a cross adjuster rod 1 into the connecting portion 3 of the main shaft 5 and tightens it with a tightening nut 13 so as to variably set a plurality of resistors mounted on the substrate to a desired value. It is a structure which moves to an XY robot (not shown) on a resistance, and makes it rotate by a control program.

As described above, when the regulator A is positioned on the resistance by the X-Y robot, the motor unit 7 is operated by a control program input to an electronic controller (not shown) to allow height adjustment and rotation.

When the regulator A enters the adjusting rod 1 on the resistor by the XY robot, the elastic member 9, which serves as a shock absorber, prevents the operation of breaking the resistance mounted on the substrate due to erroneous entry. It is comprised on the upper side.

And secondly, the adjuster B is a cross-shaped adjustment tip 15 for rotating the adjustment screw of the resistance mounted on the substrate, a plastic member 17 for fixing the adjustment tip 15, and a shaft bar from the plastic member 17. 9) a coupling 21 for connecting, a bush 25 fitted to the shaft 22 connected to the coupling 21 and mounted on the plate 22, the bush 25 and the coupling 21 An elastic member 23 formed therebetween, a second universal joint 27 connected to the shaft rod 19, a length adjusting rod 20 connected to the second universal joint 27, and a length adjusting rod ( 29) a first universal joint (31) connected to the first universal joint (31) to enable power transmission even if not vertical, a motor (35) for transmitting power to the shaft (33) connected to the first universal joint (31), and the motor And a bracket 39 for fixing the 35 to the plate 37.

The adjuster B includes an adjusting tip 15 for adjusting an adjusting screw of a resistor mounted on a substrate, and a plastic member 17 for replacing the adjusting tip 15 according to the adjusting screw shape of the resistance component. The shaft member 19 is fixed with the coupling 21 while making this plastic member 17 flexible material.

The adjuster B is configured to be interchangeably provided with various length adjusting rods 29 which can vary the distance between the resistance mounted on the substrate to be adjusted and the adjusting tip 15.

In addition, the adjusting tip 15 for adjusting the variable resistance and the small motor 35 are arranged in a straight line in the adjusting tip 15 so as to have an integral structure. The structure having two universal joints 27 and 31 between the tips 15 allows power transmission even if not straight.

[Problem trying to solve]

In adjusting the resistance value of the resistor mounted on the substrate by rotating the adjusting rod or the adjusting tip, it is pointed out that it is difficult to detect the position due to the position change of the resistance.

The adjuster B can be manufactured in a small size and can be mounted in a small area, but the structure is complicated. Even though a universal joint and a length adjusting rod are configured, the adjusting rod or the adjusting tip according to the shape of the adjusting screw adjusting groove of the resistance to be adjusted. It is inconvenient to change.

The adjusters A and B have a large structure and complexity, and the adjusting rod or the adjusting tip needs to be precisely adjusted with the variable resistor adjusting groove.

Due to this problem of functional limitations, there is a difficulty in adjusting the angle due to accurate positioning with the adjusting groove.

In addition, the rotational torsional force for rotating the adjustment screw adjustment groove of the resistance mounted on the substrate is not known, there is a problem that the breakage of the component when excessive force is applied.

As described above, it is difficult to precisely adjust the position, and according to the shape of the adjusting groove, the adjusting rod or the tip should be replaced, and the program to control the regulators A and B may take excessive force when rotating the double adjusting groove. There is a problem that acts as a large load factor in the overall system configuration, such as complicated.

[Means to solve the problem]

The present invention provides a plurality of iron cores inserted into an adjustment screw adjustment groove of a resistance mounted on a substrate, a spring formed at one end of the iron core, a guide tube for guiding the elastic action of the spring, and a fixed plate on which the guide is mounted.
