The main parts of glasses are: underfill of circuit board, encapsulation of battery protection board, heat dissipation and heat conduction silicone grease, bonding and sealing of shell, encapsulation of solder joints, etc.
Heat dissipation, interference, sound quality, endurance, weight, fixation, link, etc. need to be considered in the internal design of glasses legs. Due to the large number of parts and the narrow space, some parts are difficult to carry out dispensing operation. In addition, most of the glasses legs are made of plastic materials, which will cause deformation, which may lead to the problems of point deviation, overflow and less glue.
In order to carry out dispensing from multiple angles, it is necessary to use multi-axis motion control system, cooperate with multi-channel visual recognition lighting, grasp edge processing by visual algorithm, cooperate with laser height detection, fit dispensing trajectory, and locate precise dispensing position.
