Description

technical field

[0001] The invention belongs to the technical field of electronic component processing, and in particular relates to a fully automatic sealing welding machine and a sealing welding method for a quartz crystal resonator. Background technique

[0002] With the development of the electronic information industry, the requirements for the frequency accuracy and stability of quartz crystal resonators are becoming more and more stringent. Since the specification requirements of ±500ppm in the mid-1990s have been tightened step by step, a considerable proportion of product orders have required a frequency tolerance range of ±10ppm, and from the beginning there was no requirement for excitation level characteristics to almost all orders today. All have very strict requirements, so the control of each step in the processing process is extremely important. The traditional sealing and welding process for quartz crystal resonators is still mostly manual. The specific ope...

Embodiment Construction

[0051] For ease of understanding, combined here Figure 1-5 , the concrete structure and working mode of the present invention are further described as follows:

[0052] The specific structure of the present invention is as Figure 1-5 As shown, its main structure includes a frame 50, on which are respectively installed table top components, vacuum cover components, laser sealing and welding components and air pressure components, wherein:

[0053] Structural reference for deck components Figure 1-3 As shown, it includes a horizontal worktable 11 supported by several vertical support rods. A lower mold 12 is arranged on the worktable 11. The mold surface of the lower mold 12 constitutes a positioning surface for placing and positioning the resonator a to be packaged. In order to ensure the welding efficiency, in the actual layout, the lower mold 12 actually only needs to use two horizontal and two vertical or two horizontal and one vertical rectangular pieces to form a "mou...
