Detailed Description
The invention will now be described in further detail with reference to the drawings and preferred embodiments. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
The device for online measurement of the whole size of the printing ink of the mobile phone glass, which is additionally arranged on a printing machine and is used for online measurement of the relevant size of the printing ink of the mobile phone glass, comprises a gantry support 1, wherein a vision module 2 is fixed on a cross beam 11 of the gantry support, and a movement module 3 is arranged below the vision module.
As shown in fig. 2-3, the vision module 2 includes a vertical mounting plate 23 and a horizontal mounting plate 24 fixed to the gantry support beam, 1 line camera 21 and 3 area cameras 22. The linear array camera 21 is fixed on the horizontal mounting plate 24, and the area array camera 22 is fixed on the vertical mounting plate 23; the linear array camera is arranged on the front side of the area array camera. The 3 area array cameras are respectively fixed on two sides of the vertical mounting plate, two area array cameras are arranged on the same side of the vertical mounting plate, and the other area array camera is fixed on the other side of the vertical mounting plate. The linear array camera and the planar array camera respectively adopt images of products arranged on the motion module; the linear array camera is responsible for acquiring images of the whole product, and the area array camera is responsible for imaging a local area.
As shown in fig. 4-5, the motion module 3 includes a linear lead screw guide rail 31, a servo motor 32 for driving the linear lead screw guide rail to work, a motion detection platform 33 disposed on the linear lead screw guide rail, a groove-type photoelectric sensor, and a grating scale assembly; the motion detection platform is provided with a product jig 34, and the product jig is provided with a backlight source 35. A slide block 36 is arranged on the linear screw rod guide rail, and the motion detection platform moves on the linear screw rod guide rail through the slide block; and the motion detection platform realizes linear imaging detection when moving to the lower part of the vision module on the linear lead screw guide rail.
The working process is as follows: the manipulator grabs the product to the product tool, under the effective condition of detection, the primary positioning module on the motion detection platform can fix the product position and open the vacuum suction at first, then the motion module moves, and the linear array camera finishes the drawing through the frame signal that cell type photoelectric sensor gave and the ABZ looks row signal that grating ruler reading head gave in the product tool removal process. When the motion detection platform such as the area array camera moves to the stop position, a falling edge trigger signal is simultaneously given to the area array camera to finish image acquisition. The collected images are transmitted to measurement software, measurement is completed through an algorithm, the offset of the printed product is calculated, whether the size of the product is OK or not is judged, finally, an OK/NG signal of the product is sent to a PLC, and the offset is sent to an alignment platform. And after receiving the signal, the PLC determines whether to reject the product. In the measuring process, a compensation value is sent to a contraposition platform of the printer by calculating the offset of the glass printing ink relative to the center of the glass, and the contraposition platform of the printer is enabled to generate certain displacement according to the compensation value in the printing process, so that the printing ink printed on the glass is more centered.
While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
