Description

Technical Field

[0001] The utility model relates to the technical field of photoelectric switch waterproofing, in particular to a waterproofing device for a photoelectric switch of a cleaning machine. Background Art

[0002] Photoelectric switches are widely used in various devices in modern industry. They detect the presence of an object by blocking or reflecting a light beam. A synchronous circuit connects the circuit to detect the object's presence. Water ingress into photoelectric switches can easily generate false signals. To improve production line utilization and extend the life of photoelectric switches, a waterproof device for cleaning machine photoelectric switches is needed.

[0003] In the post-processing of glass substrates, all glass signal transmission is detected and transmitted by photoelectric switches. During the cleaning process, due to the large amount of water vapor inside the equipment, the photoelectric switch will not be able to correctly detect the glass signal if used in water vapor for a long time. Once a signal transmission error occurs, it will cause the equipment to alarm or the glass substrate to collide, and the photoelectric switch will need to be replaced. The inspection and replacement of photoelectric switches are also included in the regular maintenance work, and the internal working space of the equipment is small, so the replacement and adjustment of photoelectric switches is relatively time-consuming. Therefore, if the water vapor that the photoelectric switch contacts can be reduced, the frequency of personnel replacing the photoelectric switch will be greatly reduced, thereby reducing regular operation time, improving production line utilization, and reducing the number of purchased photoelectric switches, achieving the goal of reducing costs and increasing efficiency.
