Description of the Invention (1) The present invention relates to a method for manufacturing a cone of a picture tube having a surrounding, flat ground and welded edge for sealingly joining a display screen. The present invention also provides a device for performing the method for manufacturing the cone of the picture tube. # 'a 1Especially the television display alarm or computer monitor makes the display part combined with 1. The first is the broken glass formed by three separate ^. 邛 points, called the actual display screen, The rear part of the imaging officer, called the cone, and finally the neck of the tube that receives the injection system. 0 The tube cone has traditionally been manufactured following the following steps:-supplying the glass melting clot into a mold conforming to the outer contour of the cone,- The glass frit is cast into a cone, which has a flat surrounding, welding edge,-mechanically completing the cone, including plane grinding around the welding edge. The judge therefore 'completes the prayer of the glass clot in one of two ways to form a cone with a welding edge around it: the glass clot passes through a die that indicates the internal contour of the cone and a ring that secures the die Extruded and static. Place on a mold to form a cone 'or use a suitable mold with an edge ring on it to centrifuge to form a cone. The mechanical manufacture of the cones may include not only planar grinding around the welding edges but also, for example, grinding and faceting of the convex shafts on the cones and / or polishing grinding the joint edges. The welding edge is joined to the screen ' with an opposing welding edge thereon ' by means of a glass solder to achieve a vacuum-tight form. Pasty glass solder is applied to the welding edge of the cone. The cone is placed with the welding edge facing up.

Description of the invention (2) Tilt the metal frame. The screen is placed on the broken solder with its welding edge facing down. In the subsequent tempering operation, the solder is melted 'and the cone and screen join to form a picture tube. If it is necessary to achieve the flatness of the cone welding edge conforming to the specifications, the welding edge must be machined by grinding. As with the grinding process, a diamond grinding process or a so-called applying method can also be used. The resulting abrasive edges are destroyed by the subsequent grooving process or they already have a pressed-on chamfer. However, in either of these situations, the ground edge is established, it will have more or less sharp edges and may therefore be easily damaged due to collisions, and may also break due to grinding and grooving. These cracks may disappear during the final mechanical processing of the picture tube manufacturer, and by design, they may be trapped in the perforations or pore shields of the color display screen and thus the picture tube cannot be thrown away. In addition, in all of the above, in diamond grinding, a grinding structure is generated, and its extension crosses the welding edge. In some cases, if dust falls into the structure ', the structure will cause a high voltage discharge when the picture tube is in operation. Once again, this picture tube will no longer be usable. German patent invention DE 29 2 1 4 07 A1 describes a method and an apparatus for machining a cone part of a cathode ray tube and a vacuum tube at the same time, and also describes a cone obtained by using this method. In a special embodiment of this method, according to most of the grinding stages, that is, polishing is used, the sealing edge of the tapered portion and the like are chamfered at the edges, so that the desired sealing edge surface characteristics are obtained. In the publication Vakuura (vacuum tube), volume 29, p. 231, ff. (L979), written by Robert G. Neuhauser, it states that extruding soft metal vacuum

Description of the invention (3) Tube dense Γ glass and pottery, it points out that the grinding on the sealing edge may cause leaks. These loopholes have a negative impact on the vacuum tube. The German patent invention DE 2 6 2 9 1 4 0 A 1 describes a television picture tube and a vacuum tube and describes a method of manufacturing them. The TV vacuum tube is chemically polished in the welding edge area: in other locations. Therefore, the welded edge is a non-directional structure with a similarly engraved surface. The use of polishing acids contains more than 50% sulfuric acid to 12% hydrofluoric acid. The polished surface must be repeatedly immersed in the polishing acid. Because these needs cause the problems of worker safety and environmental pollution caused by polishing acids, if this method is used on a large scale, the possibility of large-scale application of chemical polishing is not a problem. The purpose of the present invention is to teach the lack of methods defined at the beginning, by which the welded edges will be less fragile, less susceptible to mechanical damage and will not break, and reduce the risk of high voltage discharge of the picture tube through the welded edges during operation. . This method should also be applied on a large scale without objection. With regard to the method of manufacturing a cone of a picture tube, this can be achieved in the following steps: supplying a glass melt to a mold conforming to the outer contour of the cone, casting the glass to a cone, which has a flat cone surrounding the welding edge by mechanically The body finish includes planar grinding around the welding edge and grinding the welding edge to grind the particles and smooth it with the aid of a fluid or acceleration device. In the kinescope cone of the present invention, the smoothness of the edges

Description of the Invention (4) Tan, dust and dust no longer fall into the grinding structure so easily. If the dust still remains on it, it is not likely to cause a high discharge. Because there is no directional structure, voltage can be brought into the picture tube. In addition, the cone of the present invention is less susceptible to collisions and has no possibility because it surrounds the abrasive edges. Semi-loose particles that fall into perforations or pore shields. ‘This greatly reduces the loss from glass damage or damage from perforations or void shielding and thus advantageously reduces the manufacturing cost of the picture tube. Cone cones with a non-directional, smooth structure and surrounding, non-cracked grinding edges are manufactured by the method of the present invention, wherein the welding edges use the action of abrasive particles and use a suitable device. This effect can be accomplished by speeding the abrasive particle force σ to a high speed, such as a fast rotating wheel, or by mixing the abrasive particles with a fluid in the form of a jet as a carrier for the abrasive particles. Utilizing the effect of non-directionality on the abrasive particles, the surface structure derived from the directionality of the initial grinding becomes smooth and replaced with a non-directional structure. In addition, the abrasive edges are thus surrounded and therefore less vulnerable to collisions. Another effect of this effect is that the semi-released particles formed during the grinding process are removed and therefore can no longer fall into the perforations or pore screens later. In short, the abrasive particles cause wear on the welded edges. In a preferred embodiment, a permanent jet is used as the fluid. The abrasive particles are mixed with water, and the purpose of this mixture of water and abrasive particles is to act as a jet against the edges of the weld. The good thing about water is that it is a medium that is everywhere and takes into account economic and environmental protection. Preferably, abrasive particles having a size between 100 and 600 micrometers (m) are used. With these abrasive particle sizes, the surface texture of the abrasive particles can be reached

Description of the invention (5) Make-0 The whole one by one will change the manufacturing edge on the device. The simple connection to the water container is performed. The welding edge follows a set function so that it has a fixed digital control (fee 1 e position. The process view acts on the welding width. Its orientation costs. It has a non-square picture tube, which has the condition The nozzle and nozzle are located there and the mouth. The current edge of the jet is here. The controller of the best practice is linearly guided to the center axis and rotates a rectangular shape. Therefore, the controller achieves r roller. At the midpoint of this method, it has proven to be It is advantageous to disperse the abrasive particles. The method on the edge is spatially scattered on the welding edge so the cone can move through the abrasive particle nozzle without reducing the time and direction of this machining step, and smoothing around the non-cracked abrasive edge. The method of a structured welding cone is preferably a device for applying abrasive particles to a welding edge via the device according to the present invention. In the device, the device contains abrasive particles. Device, which has a water supply source for continuous abrasive particle nozzles. Water enters the abrasive particles and the abrasive particles are mixed and appears _ through the water jet and during the grinding process, the water jets carry abrasive particles. If the grinding is aligned with the cone of the picture tube- The welding edge starts to rub. In this example, the device has a nozzle position adjustment such as a cone position. This nozzle is mounted on a sealed linear guide, and the device cannot move in its position. The cone turns, and, Because the cone is not circularly symmetrical, but the shape, the space between the welding edge and the central axis does not have to move the nozzle. The nozzle control can be detected by the nozzle cone or the flow of the cone. The signal can be transmitted to the linear guide, the processing step where the abrasive particles act on the welding edge

Description of the invention (7) It is completely different from Figure 2 ™! Figure 2 shows the abrasive weld edges obtained by conventional polishing. It has a fairly pronounced sharpened grinding edge 21, which is not crack-free. In addition, a directional structure has been produced on the surface due to grinding. If abrasive particles are now applied to the abrasive welded edges, causing friction, the result is a smooth and polished welded edge 10 (Figure 1). The original blade-shaped abrasive edge 21 was changed into a surrounding, crack-free abrasive edge 21 by friction. These edges are now less susceptible to injury from collisions than the original sharpened grinding edges 21. The oriented structure 22 has been further subjected to friction machining to become a non-directional, smooth structure 12. Dust will no longer fall into this structure, and since the directional structure no longer appears, the high-voltage discharge in polished kinescope operation will no longer occur. _ In Fig. 3, an exemplary flat 1 smoothing device is shown. The key parts of the device are the water jet and the abrasive particle nozzle 3 1; in order to make the figure clearer, the abrasive particles. Supply container and water supply source are not shown. An abrasive particle water jet directed at the welding edge of the cone 30 is ejected from the water jet and the abrasive particle nozzle. During the smoothing operation, the cone 30 rotates on its central axis. Because the shape of the cone is not circular but rectangular, the space between the welding edge and the mandrel is changed by the position of the cone and therefore also the relative position of the jet and abrasive particle nozzle 31. Therefore, the position of the jet and the abrasive particle nozzle 31 must be adjusted as a function of the cone position. to this end! The purpose is that the jet stream and the abrasive particle nozzle 31 are fastened to the simplified linear guide 32. The simplified linear guide 3 2 is rotatably connected to a probe roller 3 3. The probe roller 3 3 detects the position of the cone 3 0 and sends a signal to the simplified linear guide 3 2
