TECHNICAL FIELD

[0001] The present application relates to the technical field of quartz crystal production equipment, and particularly relates to a single-line feeding and discharging replacement mechanism for crystal oscillator production. BACKGROUND

[0002] Based on the fact that a high-vacuum environment is often required in the production process of crystal oscillators, such as frequency trimming, cap mounting and sealing, etc., the high-vacuum environment usually needs to be extracted by a molecular pump or a cryogenic pump, but the precondition is that a mechanical pump needs to extract a low vacuum in advance. If all the vacuum values are unloaded every time the jig is switched, the efficiency of the machine table is greatly affected. SUMMARY

[0003] The present application aims to provide a single-line feeding and discharging replacement mechanism for crystal oscillator production to solve the problem that the efficiency of the machine table is greatly affected when all the vacuum values are unloaded every time the jig is switched.

[0005] Further, the driving assembly comprises a motor, a telescopic cylinder, a rotating shaft, a thin gear, a thick gear and a belt transmission mechanism, the rotating shaft penetrates through the side edge of the box body, and the rotating shaft is in sealing sliding connection with the side edge of the box body, one end of the rotating shaft is fixedly connected with the power magnetic head in a same axis, the other end of the rotating shaft is fixedly connected with the thin gear in a same axis, the thin gear is in meshing connection with the thick gear, and the thick gear is power-connected with the motor through the belt transmission mechanism.

[0006] Further, the displacement assembly comprises up-and-down displacement air cylinders, guide rods and linear bearings. The up-and-down displacement air cylinders are installed right below the box body, the output shafts of the up-and-down displacement air cylinders penetrate the bottom surface of the box body and are in sealed sliding connection with the bottom surface of the box body, the support plate of the conveying assembly is fixed on the top of the output shafts of the up-and-down displacement air cylinders, the guide rods are vertically fixed on the bottom surface of the box body, and the linear bearings are fixed on the side edges of the support plate and are in sliding connection with the guide rods.

[0007] Further, the box body is provided with two sets of vacuum packaging assemblies. The vacuum packaging assembly comprises a first sealing member, a second sealing member, sealing pieces, sealing connectors and a sealing ring. The sealing pieces and the sealing connectors are fixed between the first sealing member and the second sealing member.
