Title: Method for sealing color picture tube
Inventor: FUNAKI KISHIYOU
IPC: H01J9/42
Filed: 1983-07-20
Abstract: PURPOSE:To improve work efficiency and enable positioning sealing with high accuracy by presetting an angle of revolution in which a laser beam starts passing through between through holes using a light receiving device and determining the sealing position for a bulb based on this passing start angle. CONSTITUTION:When the gap between a pair of through holes 14 starts overlapping by the revolution of an electron gun 11, a laser beam 67 passes through the gap. Accordingly, the beam is caught by a television camera 62 and is displayed on a monitor television screen 64 as a laser diffraction image. The number of pulses corresponding to the quantity of operation from a drive unit 45 is counted by detecting the sudden change of the light quantity on the screen caused by this image using a light receiving device 66 and issuing a detection signal to a pulse counter 70 through an amplifier 68. If the number of these pulses is preset in a presetting counter 72, the pulse counter 70 starts counting from the position where the passing light beam can be detected. As a result, when the electron gun 11 is set to matching state with the bulb, a counting up signal is generated and is applied to a motor control device 73 and then stops a pulse motor 46.
