SU1257715A1 - Device for applying metal containing paste on side surfaces om ceramic blanks - Google Patents

Abstract

The invention relates to coating. The purpose of the invention is to improve the quality of metallization and the expansion of technological capabilities. The paste is applied by combs 3 on the ends of the blanks located in the holder 12. To achieve this goal in the device, each metalizing mechanism is equipped with a pulley 5, an emphasis 6 and an adjusting roller 7, which ensure the combs rotate 3 by 180. The drive mechanism is equipped with adjustable cams 19 and 20 with a plate 15 connected to each pulley 5 by means of a flexible spring-loaded element 9. 2 sludge. l .l If (П Fig

Description

The invention relates to the coating and can be used in the manufacture of ceramic parts of metal-ceramic housings radio components,

The purpose of the invention is to demonstrate the quality of the metallization and the expansion of technological capabilities.

FIG. 1 shows the proposed device in the position of contact of the dies with rotating lubricating rollers, general view; in fig. 2 - the device in the position of contact of the dies with the workpiece, a general view.

The device contains a transporting mechanism (not shown) and metallization mechanisms consisting of spring-loaded carriages t, rotating lubricating rollers 2 and combs 3. Each comb 3 is rigidly fixed on axis 4, on which pulley 5, an emphasis 6, an adjusting roller 7 and torsion spring 8. The pulley 5 and the stop 6 are rigidly fixed on the axis 4, and the adjusting roller 7 is rotatably supported. The torsion spring 8 is fixed at one end to the carriage 1, and the other interacts with the comb 3. The axis 4, together with the comb 3, the stop 6 and the pulley 5, can be rotated relative to the carriage 1 under the action of a flexible spring-loaded element 9 attached to the pulley 5 . On the mounting rails 1, the adjusting screws 10 and 11, which interact with the stop 6, are fastened.

The device also contains the holder 12 of the workpieces and the drive mechanism consisting of a pneumatic cylinder 13 with a rod 14 on which the plate 15 and the head 16 are fastened. On the head 16, the cams 19 and 20 are fixed with the possibility of rotation around the axes 17 and 18 and are interconnected by a spring

21 straps which presses the knobs 20 against the tapered surfaces of the adjusting screws 22 and 23. When the screwing depth of the screws is changed

22 and 23, the tilt angle of the cams 19 and 20 defining the stroke of the carriage 1 is changed. The flexible spring-loaded elements 9 are fixed on the plate 15 of the drive mechanism, and the adjusting rollers 7 are in constant contact with the cams 19 and 20.

The device works as follows.

A transporting mechanism (not shown) places the workpieces (not shown) in the holder 12. After that, the rod 14 of the pneumatic cylinder I3, together with the plate 15, the head 16 and the adjustable masks 19 and 20 mounted on it, moves downwards. In this case, the spring-loaded carriages 1 move in the direction towards the holder 12 of the workpieces, following the inclined surfaces of the adjustable cams 19 and 20 with which the adjusting rollers 7 come in contact. The flexible spring-loaded elements 9, fastened at one end to the plate 15 and at the other end to the pulleys 5, the pulleys 5 are turned together with the axles 4, the dies 3 and the lugs 6 until the latter are in contact with the adjusting screws 10. In this case, the dies 3 turn 180 ° without touching the workpiece, due to the adjusting screws 22 and 23, which change the angle of inclination cam 19 and 20. With further lowering of the rod 14, the comb 3 suitable to a workpiece (not shown) prior to contacting them with the side surfaces of the workpiece. The paste is applied to the ends of the preform.

When the rod 14 moves upwards, the dies 3 move away from the workpiece and under the action of the torsion springs 8 rotate to the initial position and touch the rotating lubricating rollers 2. The rotation of the dies 3 ends at the moment of contact of the stops 6 with the adjusting screws 11.

Then the transporting mechanism (not shown) takes away the metallicity. bath blank, freeing holder 12 for laying the next blank.
