Smart surface mount system and line scanning identification method thereof

Abstract

The invention discloses a smart surface mount system, comprising a portal rack, a surface mount head, a board transmission system, an image collection system and a feed system. The feed system comprises a feeder base, feeder integrated control cards and an electric feeder. The board transmission system comprises a board waiting area, a surface mount area and a board outlet area. The image collection system comprises a condenser lens, a light board, heat sinks, an optical lens, a connection ring and a linear array camera. The invention also discloses a line scanning identification method for the smart surface mount system. According to the smart surface mount system and the method, the design is reasonable; through adoption of image windowing transmission, the speed and security coefficient are naturally and greatly improved and no hidden breakdown trouble exists in a transmission channel of an optical fiber; through adoption of a hard triggered photographing method, the image processing is more efficient; according to an image compensation algorithm, uncertain factors do not need to be considered, and the positioning precision and repeating precision are clearly improved; and through adoption of a linear motor, the scanning precision is improved, and the using effect is good.

Description

technical field [0001] The invention relates to a placement machine, in particular to an intelligent placement machine. Background technique [0002] Machine vision started relatively late in China, and it has only been widely used in the real industrial field for more than ten years. At present, the industry is in a period of rapid development and there is a lot of room for development. The specific performance is that the market capacity of the industry is growing rapidly, the application field is gradually expanding, and the number of enterprises in the industry is also increasing rapidly. The matching light source is an indispensable technical support for machine vision. Since high-end domestic placement machines are still in their infancy in China, line scan recognition technology is mostly used in license plate models, barcodes and other industries that require low-end. For the supporting technology required by the high-speed, high-precision and high-stability of the ...

Problems solved by technology

Since the area array camera captures images statically, there are many limitations in the use process. Due to the influence of the frame rate of the area array camera, the image acquisition speed is slow and cannot match the motion speed of the linear motor.

Affected by the field of view of the photosensitive chip of the area array camera, multiple cameras are required to shoot in segments for long strip targets, which increases the cost and the transmission of multiple images is likely to cause "traffic jam" in the optical fiber

Although the speed can be improved by increasing the frame rate of the camera, after all, the frame rate is limited, and the cost also increases. Frame loss and image distortion are fatal flaws of area scan cameras, which bring inconvenience to users.
