Description

Technical Field

[0001] The present invention relates to the technical field of optical plate processing equipment, and in particular to dual-platform welding and bonding equipment. Background Art

[0002] With the rapid development of science and technology and the widespread application of electronic products in various fields, the demand for optical plate welding equipment is also increasing. However, existing optical plate welding equipment generally adopts a single-platform working mode, which has significant limitations in welding efficiency and accuracy. Usually, when traditional equipment is performing welding operations, the positioning of optical plates mainly relies on the mechanical positioning system, which is easily disturbed by external factors in actual operations, resulting in low positioning accuracy, which in turn affects the welding quality. In addition, when performing welding operations in the single-platform working mode, it is necessary to wait until the current welding task is completed before proceeding to the next step. This working method results in a slow production cycle and low production efficiency, which is difficult to meet the needs of large-scale industrial production. At the same time, traditional equipment does not have sufficient control over the flatness of optical plates during the welding process, which can easily cause damage to the surface of the plate, seriously affecting the welding quality and yield rate.

The equipment adopts a four-camera camera positioning system, and accurately calculates the center position of the optical plate.
