Description

Technical Field

[0001] The utility model relates to a crystal bonding tool, in particular to a crystal rod crystal bonding flexible tool structure. Background Art

[0002] In the field of crystal rod slicing, the crystal rod needs to be glued to the components of the resin plate and the crystal support before being processed on the slicer. The existing bonding method is to first glue the resin plate to the crystal support with glue, press the resin plate with a certain weight of counterweight, and let it pre-cure under pressure. After the glue is cured to the point where the resin plate and the crystal support are not easily displaced relative to each other, remove the counterweight to form the first component, and then glue the crystal rod to the resin plate of the first component with rod glue at another station. Similarly, pre-cure for a period of time under a certain counterweight to form the second component, and then transfer the second component to the curing area for static natural curing, and after it is completely cured, it is processed on the slicer. In this method, the two gluing operations are performed at different workstations, which is cumbersome. In addition, the resin plate or crystal rod needs to be positioned when being bonded. The current positioning operation uses a reference line, manually aligns the reference line to bond the resin plate to the crystal holder, and then aligns the crystal rod with the reference line and installs it on the resin plate. However, the manual positioning method is prone to cause certain deviations, which affects the subsequent slicing process. In severe cases, it may also cause damage to the entire crystal rod slice. The crystal rod is expensive, and once damaged, the production loss is serious. Utility Model Content
