Problems solved by technology
[0004] In the process of laser welding OLED glass, the temperature of the welding area is very important. When the temperature rises to a certain level, the mixture of glass powder and heat-absorbing substance melts and fuses with the material to be welded. It is very critical to the sealing effect produced by welding. The current experience temperature value will vary according to the different materials. Generally, it is between 300°C and 700°C; Carry out relevant tests, lack of monitoring in the process, so when the welding temperature deviates from the normal range, it will cause a lot of consequences of poor sealing effect, so the lack of process control must be solved, and the focus of process control is the temperature of the welding zone control, so it is necessary to find an effective solution for temperature control in the process

Description
[0001] technical field [0002] The invention relates to the field of laser welding, in particular to a temperature control device and method for laser welding OLED glass. [0003] Background technique [0004] In the process of laser welding OLED glass, the temperature of the welding area is very important. When the temperature rises to a certain level, the mixture of glass powder and heat-absorbing substance melts and fuses with the material to be welded. It is very critical to the sealing effect produced by welding. The current experience temperature value will vary according to the material and the temperature range. Generally, it is between 300°C and 700°C; Carry out relevant tests, lack of monitoring in the process, so when the welding temperature deviates from the normal range, it will cause a lot of consequences of poor sealing effect, so the lack of process control must be solved, and the focus of process control is the temperature of the welding zone Control, so ...
