Abstract

PURPOSE:To facilitate the polishing work and make a polishing device simple and inexpensive by polishing the seal edge face of a funnel before the sealing with a neck tube, positioning and fixing the funnel while collating pads provided on adjacent two side wall faces of the funnel are used as a reference, and sealing the funnel with the neck tube. CONSTITUTION:The seal edge face 2a of a funnel 1 is polished with a polishing grindstone G. The polished funnel 1 is positioned and fixed on a mount 8 while polishing pads provided on adjacent two side wall faces of its wide opening end section 2 are used as a reference. A neck tube 5 located vertically to the polished seal edge face 2a of the funnel 1 is faced to the funnel 1, then the extension line of the center axis Z of the neck tube 5 passes ths center O while three collating pads 4a, 4b and 4c of the funnel 1 are used as a reference. The funnel 1 and the neck tube 5 thus faced to each other are sealed in the nonrotating state while a burner 22 is rotated.

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method of heat-welding and sealing the funnel and neck tube of a television cathode ray tube.

As mentioned above, conventionally, after sealing the neck tube to the funnel, the seal edge surface of the funnel is polished. Polishing must be performed in a maintained state, which has the drawback of poor workability, requiring a complex polishing device with high precision, and making it expensive. In addition, it is necessary to check all the seals to see if the perpendicularity of the seal edge surface to the central axis of the neck tube after polishing is as desired, which is disadvantageous in terms of man-hours, equipment maintenance, etc., and increases costs.

Furthermore, in the past, when sealing the funnel and neck tube, the burner was fixed and the funnel and neck tube were rotated to seal them. There was a drawback that the neck tube could not be sealed in the same way, and the neck tube would be sealed without being perpendicular to the panel to be attached in a later process.

To achieve the above object, the present invention polishes the sealing edge surface of the funnel before sealing with the neck tube, and then positions the funnel with reference to reference pads provided on two adjacent side wall surfaces of the funnel. Then, a neck tube whose central axis is perpendicular to the polished seal edge surface of the funnel and located on an extension line passing through the center with reference to the collation pad is placed opposite to the funnel, and then,
The funnel and neck tube are sealed by rotating the burner in a non-rotating state.

According to the present invention, since the seal edge surface of the funnel is polished before sealing with the neck tube, there is no need to consider the perpendicularity with the neck tube in the polishing process, unlike in the conventional art. Since the funnel is positioned and fixed based on reference pads provided on two adjacent side wall surfaces of the funnel and sealed with the neck tube, the perpendicularity of the center axis of the neck tube with respect to the sealing edge surface of the funnel is improved. In this case, the reference pad provided on the funnel will be used later when sealing the panel to the seal edge surface of the funnel.
By comparing with the matching pad provided on the panel, the accuracy of the correlation between the two is improved.
The perpendicularity of the central axis of the neck tube with respect to the panel is also improved.

In addition, since the funnel and neck tube are fixed in an immovable state and the burner is rotated to heat and seal the joint, the centrifugal force of the funnel, etc., does not affect the sealing process as in the conventional method. It will not spread.

According to the present invention, there is no need to consider the perpendicularity of the seal edge surface of the funnel with the neck pipe, so the polishing work becomes easier and the polishing device can be made simple and inexpensive.

Further, according to the present invention, after polishing the seal edge surface, the funnel is positioned with reference to the reference pad, and
Since the neck tube, whose central axis is perpendicular to the seal edge surface and located on an extension line passing through the center of the reference pad, is sealed facing the funnel, the relationship between the funnel and the neck tube is improved. This is equivalent to performing the sealing on the gauge surface, and the perpendicularity between the seal edge surface of the funnel and the neck pipe can be maintained with high precision.

In particular, the funnel reference pad serves as a reference when joining the funnel and panel.The funnel is positioned based on this reference pad, and the neck tube is aligned perpendicular to the seal edge surface. Moreover, since the central axis is positioned on an extension line passing through the center of the reference pad for sealing, the accuracy of the correlation between the neck tube and the panel can be improved. Therefore, a highly accurate funnel-neck tube assembly suitable for the principle of a cathode ray tube can be obtained.

Furthermore, as described above, the funnel and neck tube, which are opposed to each other, remain fixed and are sealed while being heated by a rotating burner around the abutting portion. It is not affected by centrifugal force as in the case of 1. Therefore, the funnel and neck tube can be sealed in a stable state.
