Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensing machines, and in particular to a laser auxiliary device for glue dispensing machines. Background Art

[0002] Chip packaging is to add a protective "shell" to a chip with logic functions. This "shell" has the functions of easy removal and placement, protecting the chip from physical damage and environmental influences, providing mechanical support, pin connection and electrical connection, heat dissipation and temperature management, etc., which can make the chip work more stably.

[0003] Glue dispensing machine, also known as glue coating machine, glue dripping machine, glue spraying machine, glue filling machine, etc., is an automated machine that specializes in controlling fluids and dripping and coating fluids on the surface or inside of products. It can realize three-dimensional and four-dimensional path dispensing. Glue dispensing machine is mainly used for the precise dot, injection, coating and dripping of glue and other liquids in product processes to the precise position of each product. The dispensing machine can be used to achieve dotting, drawing lines, circles or arcs, and can perform operations such as soldering flux, crystal alignment, hot pressing, and filling primer on chips and substrates.

[0004] When setting the dispensing parameters, the machine needs to be adjusted to move. Due to the lack of a reference point directly below the glue needle, the glue needle needs to be lowered to the dispensing height before the specific dispensing position can be determined. Due to the lack of a reference point directly below the glue needle of the machine, the position of the glue needle can only be estimated by visual inspection by the staff. This positioning accuracy is poor and errors are prone to occur. Utility Model Content

The dispensing mechanism 700 is used to squeeze the glue out of the glue needle 7003 to realize the dispensing operation on the substrate and the chip.

[0030] Embodiment 3 of the laser auxiliary device for glue dispensing machine
