SU1495883A2 - Apparatus for stripping-off insulation from strip wires - Google Patents

Abstract

The invention relates to process equipment for the preparation of ribbon wires for installation prior to installation and soldering them to printed circuit boards or to connectors of electronic equipment assemblies and can be used in the radio, electronic and instrument-making industries. The aim of the invention is the expansion of technological capabilities by enabling the processing of segments of wires with different lengths of transversely notched sections at their ends. The machine is provided with a mechanism for turning the feed rollers 5 and 7 in the wire feed direction, made in the form of a pneumatic cylinder 26 with a toothed rod, which is in constant engagement with gear 24, which is connected to the feed roller 5 through an overrunning clutch. A pneumatic valve 29 controlling the roller turning mechanism is connected via the sensor 28 to the decompressed condition of the wire clamping mechanism 11 with a measuring device. The drive mechanism for turning the rollers and the drive of the carriage 10 is equipped with adjustable stops. The presence of a mechanism for turning the feed rollers and adjustable stops on the drives allows the processing of long wires without turning off the IR-radiation source 13, provides for improved cutting accuracy and the possibility of obtaining wire segments with different lengths of notched insulation sections at their ends. 2 Il.

The invention relates to technological equipment for the preparation of ribbon wire for installation, and can be used in electrical, radio, equipment and other industries and is an improvement of the device

auth. No. 1170543.

The purpose of the invention is the expansion of technological capabilities by enabling the processing of segments of wires with different lengths transversely (cropped insuli at their ends.

FIG. 1 schematically shows a kinematic —scheme of an automaton; Fig, 2 - the treated area of the ribbon wire.

The machine contains a holder 1 of the coil, a mechanism 2 straightening the wire 3, a roller wire feeder comprising a shaft 4 with a feed roller 5 and a disk 6 of the measuring device mounted on this shaft, a pressure roller 7 and a wire feed drive 8 connected to the shaft 4 by means of an overrunning clutch 9, a carriage 10 with a drive of reciprocating movement along the wire feed direction with a wire clamping mechanism 11, cutting blades 12, an IR radiation source 13, an optical system consisting of a radiation flux divider 14, flat mirrors 15-17 and focusing lenses 18 and 19, the traverse 20 is kinematically connected with the adjustable drive 21 through the screw 22 and the nut 23, fixed in the middle of the traverse 20, the turning mechanism is 0

in the feed direction of the wire, consisting of gear 24 mounted on shaft 4 and connected to this shaft through an overrunning clutch 25, pneumatic cylinder 26 with a toothed rod, meshing with gear 24.

The stroke of the gear rod of the pneumatic cylinder 26 is limited by an adjustable stop 27 ...

The wire clamping mechanism 11 is provided with a decompressed state sensor 28 connected electrically with the pneumatic valve 29 controlling the turning mechanism. The carriage 10 has a bracket 30 associated with the rod of the pneumatic cylinder 31. The stroke of the rod of the pneumatic cylinder 31 is limited by the adjuster. 32 lining stop

Along the edges of the cross member 20, there is fixed on one side a flat mirror 16 with a focusing lens 18, on the other side a mirror 17 with a lens 19.

The machine works as follows.

The wire feed drive 8, rotating the shaft 4 and the feed roller 5 and the measuring disk 6 fixed on this shaft, feeds the wire 3, which, winding off the bay 1, passes through the mechanism 2 wire straightening and the carriage 10. Upon reaching the specified size, - the wire clamping mechanism 11 is woven, the wire feeding drive 8 is stopped and the drive 21 of the crosspiece 20 is turned on, which moves it in the middle. screw 22 and nut 23 across the wire. Insulation is cut by an IR beam, after which wire 3 is moved by carriage 10 by means of

pneumatic cylinder 31 by the amount set by adjustable stop 32 and equal to the sum of lengths 1 and (Fig. 2) of the incised insulation sections at the ends of the wire segment, and by moving the crosspiece 20 in the opposite direction, cutting the insulation into the next section of the wire. The carriage 10 then returns to its original position, the wire in the carriage expands, the sensor 28 closes, and a command is given to the pneumatic valve 29. The pneumatic cylinder 26 operates and its gear rod rotates the gear 24 and the shaft 4 connected to it via an overrunning clutch 25. the roller 5 between the opened cutting blades 12 and stops at a position where the cutting blades are located between the insulation incision lines. The mutual arrangement of the wire cutting line and the insulation incision lines is established using an adjustable the second stop 27, limiting the stroke of the pneumatic cylinder 26. The cutting blades 12 then operate, the pneumatic cylinder 26 returns to

the initial position, the wire feed drive 8 is turned on and the cycle is repeated.
