Platform moving type wide industrial scanning equipment and scanning method

Abstract

The invention discloses platform moving type wide industrial scanning equipment and a scanning method. The equipment comprises a frame, an upright post, a platform, a cantilever, a line-scan digital camera and a control device, wherein universal truckles are arranged at the bottom of the frame; the upright post is fixed on the frame; the platform is connected to the frame through a first sliding rail and is driven to carry out linear motion along the horizontal direction of the frame by a first motor; the cantilever is connected to the upright post through a first sliding rod and is driven to carry out linear motion along the vertical direction of the upright post by a second motor; the line-scan digital camera is connected to the cantilever through a second sliding rail and is driven to carry out linear motion along the horizontal direction of the cantilever by a third motor and carry out rotation motion along a center axis of a photosensitive element of the line-scan digital camera by a rotary motor, and the line-scan digital camera, the first motor, the second motor, the third motor and the rotary motor are respectively connected to the control device. According to the equipment and the method, the surface patterns with high precision and high color rendition on the surface of a scanned wide object can be flexibly obtained from the different perspectives.

Description

technical field [0001] The invention relates to a scanning device and a scanning method, in particular to a platform mobile wide-width industrial scanning device and a scanning method, belonging to the technical field of wide-width scanning. Background technique [0002] Scanners for obtaining high-precision patterns can generally be classified into contact and non-contact according to the placement of the scanned surface. On contact scanners, the surface to be scanned is directly covered on the support surface, such as general household and office scanners, the document is directly pressed on the transparent glass surface; contact scanners are generally suitable for documents, drawings and soft objects (such as fabric) scanning, but generally the format that can be scanned is small. On a non-contact scanner, the surface to be scanned does not directly contact any supporting surface. For example, the scanning of on-line inspection on the production line is generally non-con...

AI Technical Summary

Problems solved by technology

Existing domestic products only scan vertically and downward at a single angle

[0006] 2) There is no scan preview function, or the scan preview takes too long

Domestic products of the same kind do not have the function of scanning and previewing, nor the function of flexibly selecting the scanning area after previewing; while the scanning and previewing of imported products takes too long. close to 2 minutes

[0007] 3) Soft objects, such as wide-format drawings and thin fabrics, often cannot be flattened when placed on the platform, which directly affects the scanning quality

[0008] 4) No auto focus

[0009] 5) Lack of settings to effectively reduce stray light entering the lens

[0010] 6) Temperature control without lighting

The disadvantage of AC cold light lamps is that the electrical frequency is much lower than the scanning frequency, resulting in unstable image quality due to slight changes in brightness during the power cycle

In order to obtain stable lighting, DC LED lamps are a better choice; however, DC LED lamps have a problem of high heat generation. If the heat dissipation is not controlled, the color temperature of the light will be affected, thereby affecting the color of the image
