Detailed ways

Please refer to Figures 1-3, the present invention provides an automatic scanning device for book inventory, including: a guide rail 1, the guide rail 1 is fixedly installed on the upper edge of the bookshelf through a fixed plate 2, and the guide rail 1 is slidably provided with a drive Seat 3, the bottom of the driving seat 3 is connected with an inventory execution assembly 5 through a telescopic rod 4, which can use RFID technology to read the book information on the bookshelf. Books are image scanned. That is to say, the inventory execution assembly 5 is driven by the drive seat 3 to move along the guide rail 1, and uses RFID technology to scan and inventory the books on the bookshelf. Books adjacent to the upper and lower layers, cooperate with the vision module 6 to eliminate the book information without images in the input system of this layer, so as to ensure the effect and accuracy of RFID data reading.

In this embodiment, the inventory execution component 5 includes: a casing 51 fixed on the end of the telescopic rod 4 away from the driving base 3, the vision module 6 is fixed inside the casing 51, and the vision module 6. A line-of-sight shielding plate 52 is hinged at the upper and lower ends, and the line-of-sight shielding plate 52 is connected to the casing 51 by adjusting the thrust rod 53.

What needs to be explained is that the written pages on each shelf are the same, and should be placed neatly, because some books will protrude during the placement process due to human factors, and in the image presented by the visual module 6 There will be a phenomenon of clear and inconsistent size, which will affect the accuracy of recognition.

The line-of-sight shielding plate 52 restricts the shooting range of the vision module 6 at an angle of eight, and the angle between the two line-of-sight shielding plates 52 can be changed by adjusting the adjusting thrust rod 53, so that the vision module 6 It just can take the whole picture of the book, and the vision module 6 will not be affected by other reference objects when auto-focusing, so as to ensure the clarity of shooting.

When a certain book protrudes, it is closer to the inventory execution assembly 5 and can only take a partial range of the book under the shielding of the line of sight shielding plate 52. At this time, the adjustment thrust rod 53 shrinks, and the two lines of sight are shielded. The included angle of the board 52 becomes larger, so that the vision module 6 can just capture the whole picture of the book, ensuring the integrity of the shooting. Finally, the size of the image presented in the vision module 6 is clear and consistent, which is convenient for data analysis and processing.

In this embodiment, the line-of-sight shielding plate 52 is provided with a supplementary light 521 on a side close to the vision module 6 , and the brightness of the light can be automatically adjusted.

In this embodiment, the housing 51 is provided with a mounting plate 54, the mounting plate 54 is fixed on the end of the visual module 6 away from the bookshelf, the mounting plate 54 is slidably provided with an antenna 55, and the antenna 55 runs through the mounting plate 54 .

It should be explained that the antenna 55 is provided with a curved section, and the antenna 55 is made of a light-transmitting material, which will not affect the vision module 6. The antenna 55 is adjusted by the curved section, and is always in the scanning forward direction end and is inside the line-of-sight shielding plate 52 .
