Abstract

The invention relates to equipment for the production of color picture tubes, in particular, installations for welding electron-optical systems into balloons of color display picture tubes. The purpose of the invention is to improve the accuracy of the orientation of the electron-optical system relative to the axes of the screen of the kinescope when welding. The installation includes a slot for mounting a kresheskop, a quill for installing an electron-optical system, a quill orientation mechanism with an optical control system, a quill vertical movement mechanism, as well as gas heaters and a torch driving drive. The orientation mechanism of the quill is made in the form of a guide mounted on the quill, covered by spring-loaded rollers located on a bracket connected to the quill and connected by means of spring-loaded spherical bushings, rings and a pusher. 3 il.

The invention relates to an ORGANIZATION for the concessions of casing kinescopes, in particular, to installations for welding electro-optical-optical sltstem (AIA;) into cylinders of transparent display kinescopes.

The purpose of the invention is to improve the accuracy of the orientation of the electron-optical system relative to the axis of the screen of the kinescope when welding.

Figure 1 shows the installation is predalagaem, General view; Fig. 2 is a view A of Fig. 1; Fig. 3 is a section BB in Fig. 2.

The installation of EOS welding in color kinescopes cylinders consists of the base 1, the plate 2, and the assemblies and parts attached to them. Above the slab 2 of the tinctures 3 a slot 4 is installed, equipped with a floating support 5, base stops 6 defining the position of the kinescope in the socket, and a clamp 7. On the cylindrical guides 8 attached to the slot 4, an optical-optical control system 9 is installed, whose vertical displacement The goal of controlling the accuracy of orientation of the EOS before introducing it into the neck of the kinescope and after the end of the welding process is carried out using a flywheel 10.

The rotation of the burners 11 mounted on the spool 12 is carried out by the actuator 13.

Based on 1, a vertical movement mechanism 14 of quill 15 and burner 11 is mounted, transmitting the movement to the spool 12 through the lever 16 and to the quill T5 through the lever 17.

The orientation mechanism of the quill contains a guide 18 mounted on the quill 15, which is rotated by a pusher 20 moving during rotation of the flywheel 19. The plunger 20 acts through a lever 21 attached to the bracket 22 on the rod 23, which is connected to the guide 18 by means of mounted - a spring 24 of two spherical bushings 25 and two track gauges 26o. In addition, the spring 24 constantly presses the rod 23 to the lever 21, which at the same time presses the other end to the pusher 20.

For a joint rotation, the quill 15 and the guide 18 are interconnected by means of a bracket 27 fixed on linols, on which two rollers 28 and 29 are mounted, spanning the axle: 1 to 11 18, and the ropik 29 is set on the rotary axis 30. Spring 31, The hyperpulses 28 and 29, ensured their tight clamping to the guide 18. Such communication with the guide 18 sec. 15 ensures the absence of backlash when they are jointly rotated and allows

Q longitudinal movement of the quill 15 relative to the guide 18.

The installation works in the following way.

Wallon kinescope with inserted into

5 its throat EOS set in

the nest 4 on the floating support 5, is centered and secured with a clamp 7.

EOS is pulled out of the tip of the shtengel from the top of the kinescope and fixed in pinoli 15. The orientation of the EOS relative to the axes of the screen of the kinescope with the help of the quill orientation mechanism while simultaneously controlling its position by the optical system 9 is performed as follows.

By turning the flywheel 19, the plunger 20 is moved, acting through the lever 21 on the rod 23, which turns the guide 18 connected to it through the bushings 25 and the ring 26. The guide 18, turning, acts on the rollers 31 which are tightly pressed to it by the spring 31 28 and 29, which, through the brackets 27, rotate the quill 15.

The force closure and selection of gaps in the joints connecting the pusher 20 and the quill 15 is provided by springs 24 and 31. After the orientation is completed, the quill 15 together with the EOS rises up and enters the neck of the kinescope to a predetermined height. When the quill 15 moves vertically, the rollers 28 and 29 roll along the guide 18, ensuring that there is no angular rotation of the quill 15 around its own axis, retaining, thus, the previously set 0 with the orientation of the EOS relative to the axes of the screen of the kinescope

The burners 11, located on the spool 12, rise up and start to rotate, having carried out the preliminary heating, welding the EOS into the tube of the tube and the subsequent annealing of the place of welding.
