[0022] like figure 1 As shown, a method for positioning and grabbing electronic liquid crystal screens of different sizes includes the following steps: S101, the product is in place; S102, two cameras simultaneously collect images; S103, the cameras process the images; S104, whether to find the housing feature; S105, If the feature of finding the housing is found, 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 feature of finding the shell is not found, the product enters the manual confirmation area.
[0023] The image processing step is specifically as follows: using two image acquisition cameras to collect two top angle images of the electronic liquid crystal screen, and analyzing the images, using image matching for the two top graphics, and according to the successfully matched i...

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 precisely relates to a positioning and grasping method for electronic liquid crystal screens of different sizes. Background technique [0002] At present, due to the different sizes and specifications of electronic LCD screens, in the actual installation process, if manual transportation and installation are used, it is easy to cause cracks and pollute the surface. Inadequate installation of the LCD screen will directly affect the quality of the product 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 removed from the material box piece by piece, and then placed on the assembly line. Then it flows into the next process. Several people lift the LCD screen and align it with the back cover of the housing a little bit, and put it in place. Then check a little bit whe...
