Abstract

The invention relates to a glue spraying method, particularly to an intelligent high-speed contactless high-accuracy glue spraying method. The method includes establishing a corresponding mathematical model, and establishing a glue spraying vision algorithm and a machine vision system to provide a theoretical basis for the glue spraying method according to the forming principle of the glue spraying; collecting and processing images in motion to provide a dynamic positioning theoretical basis by using the geometric transformation technology; and measuring the glue spraying amount by using a precise weighing balance and a charge coupled device (CCD) visual positioning and measuring system to achieve closed-loop control for the glue spraying amount. According to the method, a CCD optical lens, a high-speed glue spraying valve, the precise weighing balance and a CCD measuring software are combined, a tri-axial motion platform is provided, the CCD optical lens is used for positioning components precisely, the high-speed high-accuracy glue spraying valve is matched, an on-line weighing or CCD measuring function is used for assistance, the glue amount is calibrated on line, the technical process of accurate glue spraying packaging can be achieved rapidly, quality of products is guaranteed, and the product percent of pass is improved.

Description

Technical field: [0001] The invention relates to a glue spraying method, in particular to an intelligent, high-speed, non-contact and high-precision glue spraying method. Background technique: [0002] In the flexible electronic circuit board manufacturing industry, tiny electronic components need to be sprayed and fixed for protection, so that the components are not damaged by collisions and static electricity, and the high-quality rate of the product is guaranteed, because the area of ​​the components is between 0.25 and 1 square millimeter. During the period, it is very difficult to rely on manual dispensing under a magnifying glass, and the quality cannot be guaranteed to be stable. The training period for skilled workers is very long and the training cost is high. [0003] At present, high speed and high precision are the difficulties in the glue spraying method. For the current domestic glue spraying equipment, it cannot meet the high speed and high precision glue spra...

Problems solved by technology

[0002] In the flexible electronic circuit board manufacturing industry, tiny electronic components need to be sprayed and fixed for protection, so that the components are not damaged by collisions and static electricity, and the high-quality rate of the product is guaranteed, because the area of ​​the components is between 0.25 and 1 square millimeter. During the period, it is very difficult to rely on manual dispensing under a magnifying glass, and the quality cannot be guaranteed to be stable. The training period for skilled workers is very long and the training cost is high.

[0003] At present, high-speed and high-precision are the difficulties in the glue spraying method. For the current domestic glue spraying equipment, it cannot meet the high-speed, high-precision glue spraying process requirements; while foreign glue spraying technologies are all protected by patents.
