Specific embodiment
The present invention is described in further detail in the following with reference to the drawings and specific embodiments: doing as example to the application
Further description explanation.
The present embodiment provides a kind of footprints to paste scanned imagery device, comprising: shell and the pallet for holding footprint patch, institute
Pallet is stated to be connected with housing bottom;It is equipped with lighting mechanism, imaging mechanism and transmission mechanism in the housing, the lighting mechanism is located at
Imaging mechanism is in the following, be equipped with guide rail in case top, the transmission mechanism is able to drive imaging mechanism and lighting mechanism along leading
Rail sliding.Pallet mainly holds footprint patch, and corresponding various sizes of footprint pastes, and placement location silk-screen mark is indicated on pallet,
Facilitate operation;
LED light source in lighting mechanism is arranged in linear array, and in LED light source front end, addition optical lens carries out beam shaping,
Highlighted linear light is formed, lens keep linear light beam space Illumination Distribution uniform.Integral illumination light source is with central symmetry two-side lighting
Distribution mode is presented, and the linear light of the right and left is overlapped, and improves illumination region brightness.Left and right sides light beam of light source is with 0-30 ° of angle
Irradiate footprint patch.Ensure that footprint information shows effect.
Imaging mechanism uses high-resolution camera, and line-scan digital camera uses line array CCD or CIS touch sensor.It takes the photograph
As head camera site is overlapped with lighting mechanism polishing position.When equipment is static, imaging mechanism only shoots the clear of a pixel
Picture;When equipment moving, the imaging sensor in line-scan digital camera can receive outer triggering signal, carry out image by certain frequency and adopt
Collection.
Transmission mechanism includes transmission shell, is equipped with master control borad, encoder, motor, range sensor in transmission interior of shell;
Master control borad connects encoder, motor, range sensor, and the entire workflow of control device.There are also numbers on the master control borad
According to communication module.Transmission shell is fixed on guide rail by 4 sliding blocks, and the sliding block is slidably connected with guide rail.When motor rotates
When, transmission mechanism passes through gear drive, it is ensured that does stability line movement in equipment moving part.Transmission mechanism drives simultaneously in equipment
Lighting mechanism, imaging mechanism move in a straight line.Encoder can simultaneously provide imaging mechanism pulse triggering signal in scanning process.At
Camera structure carries out Image Acquisition and the picture of single pixels all in scanning process is spliced into complete image.
Display unit, the image that will acquire show or communicate other equipment.The display unit can be serial port liquid crystal
Screen.
Footprint is placed on pallet when use and carries out Image Acquisition.Lighting mechanism arranges high-capacity LED light using linear array
Source ensures brightness of illumination, and fit lens carry out secondary optical design, the presentation of shaping hot spot highlights uniform linear light, improves light
It can utilization rate.Highlighted linear light is radiated at footprint with 0-30 ° of direction of illumination and sticks, and so that footprint is sticked dust details and clearly opens up
It is existing.To ensure that footprint information is clearly captured, the imaging position of imaging mechanism is overlapped with lighting mechanism polishing position.It is clapped when static
Take the photograph the picture of a pixel, when movement scans entire footprint patch.Master control borad controls motor, and transmission mechanism drives lighting mechanism when work
It is moved in a straight line with imaging mechanism, the image in every pixel carries out cumulative splicing at the same time, when equipment scans entire sticker
When complete footprint stick footprint information collection.Whole device ensures the stabilization of footprint patch acquisition environment using enclosed construction design
Property, reduce the interference of extraneous factor.
Specific device motion process is as follows: footprint is placed in pallet area by the device when working, range sensor
The position that identification transmission mechanism is currently located in, when transmission mechanism is not located at zero position, master control borad sends instruction control motor
Rotation, enables transmission mechanism be zeroed.Lighting mechanism powers on later, pastes and illuminates to footprint.Master control borad sends instruction control motor and starts
Rotation, transmission mechanism are moved along guide rail direction.Imaging mechanism receives encoder pulse instruction at the same time, starts image and adopts
Collection.After transmission mechanism moves certain distance, range sensor identification equipment has been moved to designated position, and master control borad sends instruction
Control motor stalls.Encoder stops sending pulse command, and Image Acquisition terminates.The image that will acquire passes through display unit
Show or communicate other equipment.
The preferable specific embodiment of the above, only the invention, but the protection scope of the invention is not
It is confined to this, anyone skilled in the art is in the technical scope that the invention discloses, according to the present invention
The technical solution of creation and its inventive concept are subject to equivalent substitution or change, should all cover the invention protection scope it
It is interior.
