Technical Field
[0001] This utility model relates to the technical field of laser welding apparatus for glass and metal, and more particularly to a laser welding apparatus for glass and metal. Background Technology
[0002] Glass materials possess characteristics such as oxidation resistance, corrosion resistance, high temperature resistance, high hardness, and wear resistance, leading to their increasingly widespread applications. However, the inherent low ductility and impact toughness of glass hinder its widespread use in engineering structures. Glass-to-metal connectors with high plasticity and impact resistance are widely used in piezoelectric sensor manufacturing and deliquescent scintillation crystal material encapsulation for harsh working environments. A laser beam is focused from the glass plate side onto the interface between silicon and glass through a 100mm focal length lens and then scanned by a scanner.
[0003] For example, patent number 202110591666.9 discloses a method for one-time welding of glass and metal. The structure includes: material selection: the metal is ring-shaped, the glass is disc-shaped, the metal is a Kovar alloy ring, the difference in thermal expansion coefficient between the Kovar alloy ring and the glass is no more than 15%, the diameter of the glass is smaller than the inner diameter of the Kovar alloy ring, and the axial dimension of the glass is larger than the axial dimension of the Kovar alloy ring; preliminary preparation: the glass and Kovar alloy ring are ultrasonically cleaned with anhydrous ethanol and pure water, and dried before use; furnace loading: the Kovar alloy ring is placed on a graphite sheet, and the glass is placed in the furnace... In this process, a graphite sheet carrying the Kovar alloy ring and glass is placed on a support frame inside a high-temperature furnace, and the furnace door is closed. The welding process involves setting the temperature and time for the high-temperature furnace, running it for high-temperature welding, and then cooling to room temperature to obtain the welded product. This invention overcomes the problem of breakage during welding caused by differences in the thermal expansion coefficients of dissimilar materials by selecting appropriate materials. By controlling the oxidation degree of iron in the Kovar metal to ferrous oxide through appropriate temperature and the reducing properties of the graphite sheet, the contact surface between the glass and the Kovar alloy is ensured to be strong. This welding method achieves low equipment cost, a relatively easy process, and a high yield, greatly reducing factors affecting welding quality.
[0004] Therefore, the aforementioned laser welding devices all rely on translation for adjustment during the welding process, and cannot adjust the angle during welding, thus limiting their practicality. Furthermore, the objects being welded require fixation with a fixed pressure plate to prevent displacement and ensure welding accuracy. To address these issues, a welding device with a fixed pressure plate can be designed, allowing for angle adjustment to improve flexibility and enhance welding accuracy. Utility Model Content
