specific Embodiment approach

[0022] Such as figure 1 As shown, a positioning and capturing method for electronic LCD screens of different sizes includes the following steps: S101, the product is in place; S102, two cameras collect images at the same time; S103, the camera processes the image; S104, whether the shell feature is found; S105, If finding the shell feature, the camera internally calculates and outputs the calculation result to the robot; S106, the robot grabs the LCD screen; S107, the robot places the LCD screen according to the calculation result. S108, waiting for the next product; S109, if the shell feature is not found, the product enters the manual confirmation area.

[0023] The image processing steps are specifically: using two image acquisition cameras to collect two top-angle images of the electronic liquid crystal screen, and analyze the images, use image matching for the two top graphics, and according to the successfully matched images, the two cameras The size and the internal calcu...

Abstract

The invention discloses a method for positioning and grabbing electronic liquid crystal display screens with different sizes. The method includes simultaneously acquiring images by the aid of two cameras; processing the images; searching for characteristics of shells; carrying out interior operation by the aid of the cameras and outputting operation results to robots; grabbing the liquid crystal display screens by the aid of the robots; arranging the liquid crystal display screens by the aid of the robots according to the operation results. The method has the advantages that an integral assembling procedures for grabbing and positioning each liquid crystal display screen and accurately arranging the liquid crystal display screen in the corresponding shell can be completed within the time no longer than 5 seconds, and accordingly the efficiency can be improved by more than 20 times as compared with the labor efficiency; work can be continuously carried out throughout the day all year round; only initial investment is required, and the cost can be correspondingly reduced by the cost for five workers; personnel operation can be omitted, accordingly, occasional errors due to personnel assembly and detection can be greatly reduced, and the assembly reliability can be guaranteed; the method is compatible to the liquid crystal display screens with different dimensions, only additional programs are required, and additional mechanical structures can be omitted; personnel do not need to be in contact with the liquid crystal display screens, and accordingly risks of product damage and product contamination can be prevented.

Description

Technical field [0001] The invention relates to the field of automation, and more specifically to a positioning and capturing method for electronic liquid crystal screens of different sizes. Background technique [0002] At present, electronic LCD screens are easily broken and contaminate their surface if they are manually transported and installed during actual installation due to their different sizes and specifications. Because the LCD screen is not installed in place, it will directly affect the product quality and its later use, causing serious consequences. [0003] Under normal circumstances, the overall process of an ordinary LCD screen is as follows: First, the LCD screen is manually transported from the material box piece by piece, and then placed on the assembly line. Then flow into the next process. Several people lift the LCD screen and align the back cover of the housing little by little, placing it in place. Then check a little bit whether the edge is installed pro...
