Description

Technical Field

[0001] The present invention is applied to the technical field of glue curing equipment, and particularly relates to an all-in-one lens glue dispensing and curing machine. Background Art

[0002] At present, industrial automation technology is gradually maturing, and equipment is highly homogenized. Effectively improving production efficiency and achieving optimization and innovation are the primary factors for customers to choose equipment, especially in the dispensing technology. The dispensing machine sprays glue at the assembly position of the product. For example, in the dispensing process of the optical lens of an electronic product, glue is sprayed between the lens and the lens barrel. The glue solidifies so that the spacer in the lens barrel is fixed, thereby preventing the lens from falling off and ensuring the quality of optical performance. Chinese patent number CN210700875U discloses a lens dispensing machine, which realizes the dispensing of lenses of different specifications, but it does not have the function of calibrating the glue path, and cannot simulate dispensing before dispensing, which easily leads to a high rework rate. In addition, the curing mechanism and the dispensing mechanism are installed on the same manipulator, which leads to delays and accumulation of lens product feeding, which is not conducive to improving production efficiency. Therefore, it is necessary to provide a lens dispensing and curing integrated machine with a compact structure, batch dispensing and calibration function. Summary of the invention
