Problems solved by technology

[0002] Nowadays, most of the existing archives and scanners used for filing of important materials are contact scanning, using a combination of rollers and conveyor belts to transport paper, because the physical characteristics of material paper are very sensitive, and part of the paper is likely to be scanned during scanning. Adsorbed to the upper platen, while the other part is flat on the lower transparent placement plate, resulting in uneven flatness of the paper during scanning, and the problem that some scans are clear and some scans are not clear; in addition, it may also be caused by paper Incomplete scanning caused by crumbs covering the paper, or uneven curling of the paper
[0003] In addition, most of the scanners in the prior art are suitable for paper with fixed specifications, such as rectangular paper such as A4 paper. Scanning of irregular paper often needs to be done manually, and the scanning efficiency is low.

Embodiment approach 1

[0050] This embodiment provides an object scanning device, such as Figures 1 to 4 As shown, it is mainly composed of a paper vertical conveying device 9 , a paper pick-and-place device 8 , a paper conveying device 4 and a scanning device 1 arranged on a frame 10 in sequence.

[0051] like figure 2 and 3 As shown, the paper vertical conveying device 9 includes a pick-up transmission mechanism and a placement transmission mechanism arranged up and down. In the placement transmission mechanism, the placement bottom plate 93 is horizontally installed on the top of the vertical switching push rod 92, and the placement bottom plate 93 is horizontally installed with a placement Conveyor belt 94, place conveyor belt 94 both sides and vertically be provided with and place side baffle 96, place the inlet end of side baffle 96 on both sides and be respectively equipped with arc correction piece 95, the correction piece 95 of both sides forms outward expansion trumpet shape. The pick-...

Embodiment approach 2

[0067] This embodiment is a further improvement of Embodiment 1. The main improvement is that the object scanning device of this embodiment also includes cleaning the dust on the upper and lower surfaces of the transparent placement plate 42, placing the upper scanning probe 11 and the lower scanning probe 11 for contamination. Lens 12 cleaning device 5.

[0068] like Figure 8 As shown, the cleaning device 5 includes a cleaning clamp bar 51, a slider 52, and a guide rail 53. The guide rail 53 is horizontally fixed on the frame 10 along the translation direction of the transparent placement plate 42, between the scanning area and the paper pick-and-place device 8, The slide block 52 is slidably connected to the guide rail 53 , and one end of the cleaning clamp bar 51 is horizontally connected to the slide block 52 , and the plane where the transparent placement plate 42 is located is located between the upper and lower cleaning bars of the cleaning clamp bar 51 .

Embodiment approach 3

[0071] This embodiment is a further improvement of Embodiment 2. The main improvement is that the object scanning device of this embodiment also includes the ability to blow the paper to be scanned flat during scanning to improve the integrity, uniformity and clarity of scanning. Jetset 2, such as Figure 9 and 10 , The air injection device 2 includes an air injection box 22 and an air injection shell 21 with several air injection holes on the side of the bottom surface, and some air injection holes on the side of the air injection shell 21 form an angle of 45° with the horizontal plane. The jet box 22 is fixed on the frame 10 and communicates with the inner cavity of the jet case 21 through the jet pipe 23, and the bottom surface of the jet case 21 is arranged parallel to the transparent placement plate 42 and is located directly above the scanning area.

[0072] After the paper to be scanned on the transparent placement plate 42 is moved into the scanning area, it is just l...

Abstract

The invention relates to the field of automatic production, and discloses an object scanning device which comprises a paper vertical conveying device, a paper taking and placing device, a paper conveying device and a scanning device which are sequentially arranged on a rack. The paper vertical conveying device is provided with a piece taking conveying mechanism and a placing conveying mechanism which are arranged up and down and connected with a taking and placing suction cup of the paper taking and placing device, and the taking and placing suction cup is further connected with a transparent placing plate in the paper conveying device. In the scanning device, an upper scanning probe and a lower scanning probe are respectively installed on the rack and above and below the scanning area, and after the transparent placing plate horizontally moves into the scanning area, the transparent placing plate is located between the upper scanning probe and the lower scanning probe. According to the equipment, through the arrangement of the paper vertical conveying device and the paper taking and placing device, paper to be scanned can be automatically conveyed and taken out, through the arrangement of the paper conveying device, the equipment can adapt to paper of different specifications and irregular shapes, and non-contact scanning can be achieved.

Description

technical field [0001] The invention relates to the technical field of automatic production, in particular to an object scanning device. Background technique [0002] Nowadays, most of the existing archives and scanners used for the filing of important materials are contact scanning, using a combination of rollers and conveyor belts to transport paper. Because the physical characteristics of material paper are very sensitive, part of the paper is likely to be scanned during scanning. Adsorbed to the upper platen, while other parts are spread flat on the lower transparent placement plate, resulting in uneven flatness of the paper during scanning, and the problem that some scans are clear and some scans are not clear; in addition, it may also be caused by paper crumbs obscure the paper, or the paper is curled unevenly and the scan is incomplete. [0003] In addition, most scanners in the prior art are suitable for paper with fixed specifications, such as rectangular paper suc...
