Pickup Design For Dry View Laser Imager

As an important method for medical diagnosis,medical image has become more and more general in outpatient service.Dry View Laser Imager makes diagnosis more fast and easy.Due to the imbalance of economic development,the demand for low cost printers in the developing regions is increasing.As the core component of Image,Pickup Assembly decides the cost of Imager.But the second generation's cost is very high because of structure design with flexible steel rope.So the third generation with low cost is very attractive for developing regions.The design that mentioned in this article meets the requirement and very important for medical system.Based on the design of second generation,summarize the weak point and list the item for improving.Set the specification of the third generation according to the requirement from the market.After geometry analysis,build 3D mode and simulate the structure.Based on the calculation,design crank slider mechanism for pickup.After structure design finished,select step motor as driver and design worm-gear transport as reducing gear.Meanwhile,select the plastic bearing from IGUS Company as pin connection.After deciding the commercial part,verify the life cycle,load parameter and cost goal.Make a lot of test after production released and get feedback from the test.According to the information in the testing,improve the performance for the third generation of pickup assembly.The crank slider mechanism is a typical form as transmission and used very widely in all business.But it is the first in the word as core component of pickup assembly.It had been accepted by printer because of low cost,simple structure and little volume.Now this structure had been more popular.
