Description

Apparatus for assembling a quartz oscillator}

The present invention relates to a crystal oscillator assembling apparatus, and more particularly, to a crystal oscillator assembling apparatus for improving working speed and precision in a process of applying a silver liquid to a quartz plate and seating on a base.

A crystal oscillator is a device in which electrodes are connected to both sides of a quartz plate in which crystals of quartz are thinly cut in a specific direction. A crystal oscillator generates vibration signals that resonate with its natural frequency when an AC voltage is applied to both electrodes. Has

Such a crystal oscillator is typically processed into a shape as shown in FIG. 1 by applying a silver solution (3) to both ends of the quartz plate and then rests on the elastic piece (2) located above the lead (4) of the base (1) It goes through the process.

For the above process, as shown in FIG. 2A, the first hand 10 and the second hand 11 reciprocating in the same direction at the same time on the horizontal axis, the silver liquid applicator 8 and the quartz plate support panel 6 And a base support panel 7 have been widely used. Here, the first hand 10 serves to adsorb the quartz plate 5 and place it on the pedestal 9, and the second hand 11 is a silver liquid through the silver liquid applicator 8 in the pedestal 9. The coated quartz plate 5 is adsorbed and assembled to the base 1. In addition, the correction plate support panel 6 and the base support panel 7 is a member for placing the correction plate 5 and the base 1, respectively, is transferred to the X-axis and Y-axis so that the correction plate 5 is sequentially Make sure that it is seated in (1).

However, the above-described method requires the bulky plate support panel 6 and the base support panel 7 to be transferred to the X and Y axes, and the first hand 10 and the second hand 11 to be moved. At the same time, there is a weak point that the work speed must be slow because it must be transported horizontally.

In addition, when the modification plate 5 is placed on the workbench 9 and the second hand 11 is attached to the base 1 so as to be aligned with each other, alignment work must be performed.

Meanwhile, in the related art, as shown in FIG. 2B, the silver liquid applicator 8, which is provided on the left and right sides of the pedestal 9, is horizontally driven on the rail 12 independently of each other by a separate actuator. Since the silver liquid coating operation is performed, the right and left silver liquid coating points of the correction plate 5 are different from each other, so that product defects frequently occur.

The present invention was devised in consideration of the above problems, and provides a crystal oscillator assembly device that increases work efficiency by allowing a silver solution coating process and a base seating process on a quartz plate to be made through a single hand. The purpose.

Another object of the present invention is to provide a crystal oscillator assembling apparatus that prevents the occurrence of the error of the silver liquid coating point by allowing the silver liquid coating device for applying the silver liquid to the crystal plate at the same time (Sliding) on both sides of the crystal plate.
