Description
Technical field
The present invention relates to a kind of pcb board automatic defect detecting devices, belong to industrial vision detection technique field.
Background technique
For a long time, manufacturing industry is all the important component of national economy, is the main battle ground of scientific and technical innovation.With in recent years
Carry out scientific and technical high speed development, global manufacturing has welcome the good opportunity developed to comprehensive automation.Completely new automation
Technology and information technology are further merged with manufacturing technology, and manufacturing industry is promoted to have changing for profound influence
Leather.Currently, science and technology is all being greatly developed in countries in the world, pushes manufacturing industry high speed development, and propose multiple industrial developments
Plan, for example, " industry 4.0 " plan that German Government proposes, " manufacturing industry returns plan " and industry that U.S. government proposes are mutual
Networking, " made in China 2025 " plan that Chinese Government proposes, " society 5.0 " and Korean government that Japanese government proposes propose
" manufacturing industry innovation 3.0 " etc..Wherein, " industry 4.0 is planned " of most great reputation points out to melt Internet of Things and manufacturing industry depth
It closes, promotes the generation of the fourth industrial revolution.
Industry 4.0 is a complexity and huge system, and the development intelligent manufacturing equipment proposed needs to solve environment
Multiple key technology difficulties such as Intellisense, intelligent control, system reliability.And mechanical vision inspection technology is to solve environment intelligence
The key with this problem of intelligent control can be perceived.Mechanical vision inspection technology be using machine vision replace human eye, human brain come
It detected, measured, being analyzed, being judged and decision, being that the mankind imitate itself visual ability and realize the important of automatic detection
Means.Similar with the visual information of the mankind, machine vision technique can provide in manufacturing environment 70% or more information, information shape
Formula is the most intuitive.Compared to previous traditional sensing techniques, mechanical vision inspection technology is mainly had the advantage that
(1) the intelligent simultaneously incomparable stability of possessor of height；
(2) extraneous abundant information can be obtained by visual simulation human visual perception ability, and imaging means are abundant；
(3) there is high Detection accuracy and rate；
(4) there is stronger real-time, can satisfy the real-time detection demand of bulk article.
Therefore, oneself warp of mechanical vision inspection technology is detected in all types of industries is used widely.Mechanical vision inspection technology
Application so that manufacturing the degree of automation is greatly improved.With the development and maturation of mechanical vision inspection technology, not
Coming it will be more widely used in manufacturing industry.
Current era is information-based fast-developing, brings great convenience to the life and work mode of the mankind.Informationization is
Through becoming the important feature of global economic and social development, social change evolution is pushed.Nowadays, IT industry slowly becomes
One of the pillar industry in the whole world.And load of the printed circuit board (Printed Circuit Board, PCB) as information technology
Body provides support for all kinds of electronic devices, just plays an increasingly important role.From we usually live in hand it is mechanical, electrical
Brain all can't do without the figure of pcb board to aircraft, the satellite of military project.
The high speed development of science and technology promotes the production of pcb board more to refine, structure also more sophisticated.But pcb board refines
Production process and the complicated structure design probability that causes pcb board production process to go wrong greatly promote.Qualified pcb board
It must assure that route, line width, line-spacing etc. meet design requirement, any one, which goes wrong, can all influence the final matter of product
Amount generates useless plate.Therefore, how in the case where meeting efficiency production meet quality pcb board have become numerous colleges and universities and
The key content of scientific research institution's research.The common defect of pcb board has short circuit, open circuit, burr, notch, hole etc., exists in order to prevent
There are these problems in last one of check process of pcb board production, it is necessary to just detect to it in the PCB bare board stage, to the greatest extent
It early finds the problem, reduces useless plate rate, Improving The Quality of Products.
There are two main classes for currently used PCB detection method: electric test and vision-based detection.Flying probe is a kind of common
Electric test method, which predominantly detects the short circuit and breaking phenomena of route, has certain limitation, Bu Nengjian
The defects of gaging hole hole, remaining copper.The current mainly artificial range estimation of domestic common visible detection method.Artificial range estimation refers to that use is put
Big mirror or microscope, testing staff search circuit board defect using naked eyes to which whether decision circuitry plate qualified, and determine into
The time of row correct operation, it is most traditional detection method, but the accuracy manually estimated relies on the subjective judgement of people, may
There can be subjective error, standing cost is also higher, and detects will also result in great bear to the health of testing staff for a long time
Load.With the high speed development of machine vision and mode identification technology in recent years, all types of industries detection based on machine vision is just gradually
It rises.
