Automatic welding and cutting device for mask and panel of flat square CRT

摘要

The present invention relates to a mask for manufacturing a planar rectangular CRT, a nine-point alignment by mask clamping and stretching, X, Y, θ positioning, and transfer and correction of image processing data. It relates to a mask of a flat square CRT and an automatic panel welding and cutting device for automatically welding and cutting the rails attached to the panel.;The prior art realizes that even if the precision machining of the mechanical part and the precise control of the control part are realized under optimum conditions, since the mask cart is set under the clamping and the stretching die by the vertical movement of the cam drive, the error of positioning Inevitably, even if the mask camera and the panel camera coincide at each center, data recognition is performed based on different centers in different spaces, so that a difference occurs between the two common centers. It is difficult to automatically assemble, resulting in a decrease in productivity due to defects.;According to the present invention, the processing unit 50 performs position photographing and alignment of the mask and panel, welding and cutting using a laser beam, and coincides with the center of the mask and panel camera by the processing unit 50. The mask cart 60 to be supplied to the processing unit 50 and the panel are guided and aligned, and the panel is supplied to the processing unit 50 in accordance with the center of the processing unit 50 and the mask cart 60 Macare. The panel cart 70 consists of a flat rectangular CRT mask and a panel automatic welding and cutting device, and a system centering the center of the mask camera and the camera for the pennel (C *), and the panel cart is a fixed center. It is fixed at (C *) and the mask cart is also rotated about this center to eliminate the error caused by the feed of the cam drive driver.
