Description

Technical Field

[0001] The utility model relates to the technical field of quartz crystals, in particular to a partition stacking device for a quartz crystal coating fixture after the placement of magnets. Background Technique

[0002] In the production process of quartz crystal oscillators and quartz crystal resonators, the coating process is one of the key processes affecting the electrical performance of products. Its main purpose is to coat a metal film with a set thickness on the front and back sides of the cleaned quartz wafers, and use this metal film as the positive and negative conductive electrodes of the quartz crystal.

[0003] During the coating process of quartz wafers, the wafers are positioned by a coating fixture with several small magnets (magnets). Therefore, first, the magnets need to be placed on the coating fixture according to the set magnetic pole directions. In addition, after the used coating fixture is cleaned, the magnets need to be replaced and repositioned. As quartz crystal oscillators and quartz crystal resonators are gradually developing towards miniaturization, tens of thousands of workpiece coating operations can be completed simultaneously in the quartz wafer coating process. Therefore, a large number of coating fixtures are required. After the magnets are placed on the coating fixture, it is also necessary to ensure the stability of the magnet positions on the coating fixture to avoid mutual extrusion and collision during storage and storage. It can be seen that the storage of the coating fixture after the magnet placement has become an urgent problem to be solved by production enterprises. Content of the Utility Model
