SU686804A1 - Arrangement for winding of wire around pins of joining panels - Google Patents

Description

The invention relates to the field of process automation, the production of electronic equipment, namely, automatic software-controlled devices for mounting electronic units by wrapping,

A device for winding wires onto pins of backplanes is known, which contains ground-mounted on the base of the feed mechanism and wire segments, stripping of the ends of the wire and tools for winding. In this case, the wire feed mechanism is made in the form of a pair of rollers feeding the wire into the channel. The wire stripping and stripping mechanisms are installed along the channel length, and the wrap tool is installed. At the wire exit from channel 1, the wire from the coil is fed into the channel by the feed rollers, where it is cut to the desired length, cleaned and grabbed by the wrapping tool.

However, such a device is not reliable when working with conductors of low rigidity. The currently used wire for winding wires of small diameter (0.2 mm and less) by the pushing method cannot be fed into the channel and the tool for winding.

The purpose of the invention. - increase the reliability of the device.

This is achieved by the fact that the device for twisting the wires on the pins of the backplanes, containing the base, the wire feeder and the lengths of wire, stripping the ends of the wire and the tools for wrapping, has an additional wire stretch mechanism consisting of three rollers between the tools for wrapping. Two of which are located on the base on one side of the wire feed axis tangent thereto, and the third is mounted for reciprocating movement by means of a drive on the other side of the wire feed axis. In this case, the wire feed mechanism is made in the form of a carrier, the axis of rotation of which is placed in the middle of a winding tool.

FIG. 1 shows the kinematic diagram of the device; in FIG. 2 - the device, front view; in fig. 3 and 4 - tool for wrapping with the mechanism of its turning and feeding; in fig. 5 and 6 — wire feed mechanism in FIG. 7, 8, and 9 are the stages of charging the wire into a wrap tool. The machine contains mechanisms 1, 2 and 3, respectively, of feeding the wire, cutting the wire, stripping the ends of the water, tools 4 for wrapping, and a wire pulling mechanism between the tools for wrapping that regulates the wire feed amount 5 and strips its ends from isolating together with mechanism 3. All mechanisms are suitable for cam-type cam mechanism 6. {Wire feeding mechanism 1 (see fig. 1, 5 and 6) from coil 7 is designed as a carrier 8, the axis of rotation 9 of which is installed between the wrapping tools 4. The carrier 8 is controlled by the cams 10 of the distribution mechanism 6 through the rail 11 and gear 12 mounted on the carrier axis. The stripping mechanism 3 (see FIG. 1) of the ends of the wire 5 is made in the form of clamped grippers 13, the jaws of which are set symmetrically to the plane of the wire 5 supply, and controlled by the cams 14. The mechanism 2 of the wire segments 5 is installed at the outlet of the wire 5 from the feed mechanism 1 and is completed in the form of a knife controlled by a cam 14. The winding tool 4 (see FIGS. 3 and 4) contains a winding spindle 15 connected to the bolt 16 by a slide 17. In the spindle 15 a pin 18 is removed for winding and charging the wire 5 into spindle 15. A pin on a pin 18 (see Fig. 7, B) 19 kryuchepodo Nogo profile for gripping the wire. The wrapping tool is equipped with a pivot mechanism and feeding it to the output of the connecting panel 20 (see Fig. 3 and 4), consisting of a cam 21, a lever 22, a rail 23, gears 24 and 25, a rail 26, which is mounted in the housing 16 and gear 27, the axis of which is the axis of rotation of the spindle 15. The gear 27 is installed in the groove of the housing 16 and engages with the lifting rod 28 of the pin 18. Between the wrapping tools 4 an additional drive mechanism 5 is installed, consisting of three rollers: two rollers 29 are placed on the base on one side of the feed axis rovoda 5 with respect to it, and the third roller 30 is installed on the other side of the axis of the wire 5 with the possibility of reciprocating movement by means of a drive in the direction between the rollers 29. The housing 16 of the twist head and its other mechanisms are suspended on the rod 31, Moving on the traverse 32, the bed of the coordinate recorder 33. The electronic part of the machine is mounted in the control unit 34, which performs the address search and control of the cam cam 6. The machine works as follows. From the coil 7, the wire 5 is loaded into a slider, which is fed into the pick-up area of the wire end by the planet carrier 8. The water-head 8 catches the wire 5. As the cam 10 rotates, the rail 11 moves and rotates the carrier 8 through gear 12 by 180. from the coil 7 and placed between the knife and the matrix of the mechanism 2 segments, into the shed of the tongs 13, between the rollers 29 and 30. The wrapping tool 4 is at this time removed from the wire laying area. Further, at the command of the control unit, the roller 30 moves in the direction between the rollers 29 and takes the position shown in FIG. 1 dotted line. Due to the fact that one end of the wire 5 is clamped in the carrier 8, there is an additional extraction of the wire 5 from the coil 7. The length of the wire is adjusted by the amount of movement of the roller 30. Then the cams 14 clamp the wire in the grippers 13 and turn on the mechanism 2, cutting it off. After that, the cam 35 opens the clamp of the carrier 8 to release the wire, and the roller 30, at the command of the control unit, makes a second movement, continuing to pull it out. At the same time, the ends of the wire are pulled out from the tongs 13, pulling off the insulation from the ends. At this time, the cams 21 move the spindles 15 of the tool 4 dp to the wrap, positioning them so that the wire is placed in a hook-like bald spot 19 of the pins 18. Next, from the cam 21, upwardly transmitted to the rail 23 via the lever 22. the arrow rotates the gear 25, which moves the rail 26 to the left. Rake 26 rotates the shaft with gear, 27. The second gear 27 at the other end of the shaft moves the rail 28 upwards, which pulls the pin 18 into the spindle 15 (see Fig. 7). When the 18 volt pin is nets and thereby wire 5 into the spindle 15, the rail 28 will select its turn and stop moving. As the gear 27 continues to rotate, the spindle 15, which can rotate around the axis of this gear, will begin to run on it with the rack 28 and rotate 90 to the panel 20. With the further movement of the rail 26 to the left, the rotation of the gear 27 will stop as the spindle reaches. until it stops, i.e. stop turning.

and the rail 26 will begin to move the entire spindle to the left, putting the pin 18 on the backplane pin. After that, wrapping is performed. During the reverse course, all movements will be repeated in reverse order. Then the cycle repeats.
