Another purpose of the invention is toprovide a sealing and welding method, and therefore the working efficiency and the finished product quality of the full-automatic sealing and welding machine for the quartz crystal resonator can be remarkably improved.

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...

Problems solved by technology

The above-mentioned traditional semi-automatic production method has the following problems and hidden dangers: First, the manual operation method has hidden dangers in production safety. If the operator is inattentive and tired, it is easy to cause incoordination between the hands and feet, which will cause the tweezers to pick up the product. When the hand and the hand are not fully returned to the safe zone, the switch is stepped on, and the pressed mold will cause physical injury to the operator

Secondly, manually clamping the resonators one by one is easy to make mistakes, resulting in the separation of the resonator and the upper cover, causing pollution and scratches to the electrodes of the resonator wafer, resulting in hidden quality problems of the sealed resonator

Again, the products are manually operated one by one, with many affected factors and low work efficiency

Finally, in order to match the output of the previous process, it is necessary to invest money to increase the sealing equipment and operators, which increases the production cost
