According to actual needs, above-mentioned mobile mechanism 2 specifically can be set to include power mechanism and executing agency structure,
Wherein, power mechanism specifically can be set to driving motor, driving one of cylinder and drive cylinder, and effect is can to mention
For power to executing agency, so that executing agency drives image analyzer 3 to move；Executing agency can be set to have empty enough
Between the frame structures of a certain number of image analyzers 3 is installed, and the frame structure can transmit the movement of power mechanism and dynamic
Power, to realize the function of synchronous scanning；Certainly, the set-up mode that mobile mechanism 2 can also have other different, can as long as meeting
Image analyzer 3 is fixedly mounted and is able to drive image analyzer 3 and is moved in the horizontal direction so that 3 synchronous scanning of image analyzer
And obtain material 01 to be scanned picture on surface set-up mode within the scope of protection of this application, herein will no longer one by one
Expansion.
Further, mobile mechanism 2 may be arranged as include crossbeam 21 and the first driving mechanism mechanism, wherein it is horizontal
Beam 21 is arranged along the moving direction for being horizontally and perpendicularly to image analyzer 3, and crossbeam 21 is used to that image analyzer 3 to be fixedly mounted, the
One driving mechanism is connect with crossbeam 21,3 energy of image analyzer under the action of the first driving mechanism, on crossbeam 21 and crossbeam 21
Enough to move in the horizontal direction, which is specially the length direction of material 01 to be scanned.

Protection scope within.
Further, above-mentioned image analyzer 3 specifically can be set to contact-type image sensor (Contact
Image Sensor), and due to needing to carry out large-sized flexible material contact type scanning, the scanning of image analyzer 3
Area coverage needs are sufficiently large, and multiple images scanner 3 is taken to splice the mode of installation staggeredly to increase scanning covering surface here
Product, i.e. any two adjacent image scanner 3, which are staggeredly spliced, to be installed on crossbeam 21；The setting quantity of image analyzer 3 can be with
It is adjusted according to actual scanning needs.
In order to optimize above-described embodiment, above-mentioned image-scanning device further includes roller bearing 4, and the roller bearing 4 and the rotation of crossbeam 21 connect
It connects, since material 01 to be scanned is mostly flexible material, and flexible material has the characteristic of flexible denaturation, and flexible material is in work
Make there may be gauffer problem is caused due to spreading out not exclusively in plane, when image analyzer 3 scans, roller bearing 4 is used for will
Material flattens, to prevent 01 protrusion of material to be scanned, that is to say, that and roller bearing 4 can compress material 01 to be scanned, so as to
It avoids causing image to obtain inaccuracy so that influencing image obtains precision because material 01 to be scanned is raised；It should be noted that
Above-mentioned roller bearing 4 is installed on the front of image analyzer 3, i.e., improves image by way of first pressing and scanning afterwards and obtain precision.
It on the basis of the above, can be by the left and right sides of roller bearing 4 in order to realize that roller bearing 4 is rotationally connected with crossbeam 21
Mounting base 5 is set；Specifically, the center of any mounting base 5 is equipped with mounting hole, the mounting hole and roller bearing 4 are coaxially disposed；Installation
It is additionally provided with installation axle 6 on seat 5, which is fixed in the end of roller bearing 4 and for being arranged in mounting hole, so,
Roller bearing 4 can be rotationally connected with mounting base 5 by installation axle 6.
In order to prevent due to 01 thickness of material to be scanned is blocked up and cause roller bearing 4 compress when 4 stress of roller bearing it is excessive, Ke Yi
Elastic component 7 is respectively set in the two sides of roller bearing 4；Above-mentioned mounting base 5 further includes being set to other than the mounting hole for being set to center
The lower end of the connecting plate of two sides of mounting hole, any side connecting plate is equipped with elastic component 7, so, when roller bearing 4 compresses material to be scanned
When expecting 01, elastic component 7 can slow down 4 stress of roller bearing using the elasticity of itself, so as to improve the service life of device.
In addition, according to actual needs, above-mentioned elastic component 7 specifically can be set to spring assembly, and work as 4 rolls forward of roller bearing
When, the spring in spring assembly is in elongation state；After roller bearing 4 is lifted with crossbeam 21, spring is in compressive state.It should
The effect that spring assembly is formed is similar to the effect that damper generates on vehicle, rolling when can not only prevent roller bearing 4 from compressing material
4 stress of axis is excessive, and can play the effect of damping to a certain extent.
The set-up mode structure of above-mentioned image-scanning device is simple, work efficiency is high, at low cost, can meet image simultaneously
The demand of the precision of speed and outline identification is acquired, and can achieve the needs that extraction accuracy is preset in image border, can be expired
Sufficient Edge extraction precision is less than the requirement of 0.01mm；Meanwhile being scanned relative to tradition, above-mentioned set-up mode does not need adding
Increase the fixed bracket of camera above construction equipment, can simplify structure, reduces production cost.
