Description

one

The invention relates to manufacturing equipment for the manufacture of electric coils and can be used in enterprises of the radio, electronic and electrical industries.

A known machine for manufacturing electric coils, comprising a spindle with a mechanism for fixing the coil frame, a tension device, a wire spreader mounted on a carriage associated with a reciprocating drive, spindle along the spindle, a mechanism for fastening the wire on the frame, a cutting device and a mechanism for the formation of leads and conclusions 1.

The machine works in the following way.

The frame of the winding coil is inserted into a collet connected to the collet by a microswitch which closes, as a result of which the motor is turned on and the first winding is wound. When the specified number of turns is reached, the motor stops smoothly, and three pins slide out on the output disk. The motor turns on again and turns the spindle one turn. In this case, the coiled wire forms a loop around the extended pins. Then the pins are pulled back by the action of the springs, clamping the loop formed on them to the water drive disk B1. Next comes the winding of the second and third windings. The output of the second winding is wound on the other three pins, and the output of the third on the next two. The end of the wire, fastened under one of these pins, is hooked onto the wire retraction lever and led to the mechanism of the initial fastening of the wire. Each of the loops formed is cut by knives. Thereafter, the collet is opened and the coiled wound is released. The finished spool is removed from the collet, and the machine is ready for winding the next spool. Traction number of turns

5 of each winding is set by a software device.

The design of the mechanism for pinning allows one single coil to be wound with one more time with the number of windings limited by the number of pin groups on the disk of the leads. In addition, such a mechanism for pinning provides the coil winding with only one wire, which reduces productivity, since it requires stopping the machine when changing the size of the wire.

The aim of the invention is to increase the productivity of the machine.

This is achieved by the fact that the proposed machine contains a platform with devices for clamping wires, equipped with a drive reciprocating movement along the spindle, and the mechanism for the formation of taps and leads is made in the form of a swivel lever located on a carriage that carries an asterisk on the free end with a groove on the outer surfaces and a mechanism for fixing the wire and associated with the drive reciprocating movement relative to the carriage. The machine may be equipped with a mechanism for twisting taps, comprising a spring-loaded hook with reciprocating drives perpendicular to the spindle and rotation.

FIG. 1 shows the proposed machine, kinematic scheme; in fig. 2 is a view along arrow A in FIG. one; in fig. 3, 4, 5 - the position of the elements of the mechanism for the formation of taps and conclusions at various moments of work; in fig. 6, 7, 8 - the position of the elements of the machine when twisting taps.

The machine comprises a spindle 1 with a collet 2 for fastening the frame 3 of the winding-up roller, an actuator 4 for communicating rotational movement to the spindle, a spring 5, reels 6 with drives 7 and tensioning devices 8 (Fig. 2). The number of bobbins and tensioning devices corresponds to the sizes of the winding wires. The mechanism for arranging the wire contains a carriage 9 with a drive 10 of its reciprocating movement along the axis of the spindle 1. On the carriage 9 there is a brace 11 on which the guide roller 12 is mounted. The adhesive dispenser 13, the electromagnet 14 and the drive. 15 constitute a mechanism for fastening the end of the wire to the coil frame (FIG. 2).

On the carriage 9 in the bearings, the axis of the pivoting lever 16 is fixed with the drive 17. The electromagnet 18 and the two shoulders lever 19 provide for the movement of the axis of the lever 16 in one direction along the axis of the spindle. Spring 20 provides for the return of the axis of the lever to its original position. At the end of the lever 16, an asterisk 21 with a groove on the outer surface for accommodating the wire and a latch 22 for fixing the wire are console mounted. The latch is provided with a spring 23. The latch opening is provided by a stop 24 mounted on the carriage 9. On the carriage 9 there is a mechanism for twisting the taps consisting of a hook 25 fixed in the initial position by the spring 26 of the hook 27 providing rotational movement of the hook and an electromagnet 28 providing the hook with two shoulders lever 29 translational motion. On platform 30, associated with a reciprocating movement actuator 31 along the axis of the spindle 1, mechanisms are installed for changing the winding wire. The mechanisms include guide rollers 32,

clips 33, electromagnets 34, pivot stops 35 and electromagnets 36, which allow the lever 29 and the stops 35 to rotate. For wire pieces, the machine is equipped with scissors 37 with an electromagnetic drive 38. The machine operates in automatic mode with a software control unit (not shown).

Before operation, the mechanisms of the machine are in the position shown in FIG. 1 and 2, the frame of the coil is fixed on

spindle 1, the ends of the wires are passed through the tensioning devices 8 and fixed in the clamps 33. When the machine is turned on, the drive 31 moves the carriage 30 until the axis of the desired wire and the groove axis of the sprocket 21 are in the same plane. Further, an electromagnet 36 is turned on, which rotates the stop 35 to the position shown in FIG. 3. Turn on the actuator 17 and the lever 16 rotates from the leftmost position to the rightmost position,

where the asterisk 21 meets the wire. The latch 22 cooperates with the stop 35 and clamps the wire on the sprocket 21. Next, the electromagnet 34 is turned on and the wire is released from the clamp 33. The actuator 17 is turned backward, the lever 16 is moved to the position shown in FIG. 4. At the same time, the coiled wire passes from the groove of the roller 32 to the groove of the roller 12 of the wire pickup mechanism. Then the actuator 15 is turned on and the metering device 13 is lowered and squeezes the glue onto the wire 7 at its contact with the frame 3. After gluing the wire, the metering device returns to its original position, and the lever 16 by the electromagnet 18 moves along the pinch axis to the extreme rear position (Fig. 1 ). In this case, the latch interacts with the stop 24 and releases the wire 7. So get the initial output of the roller. The wire is wound onto the frame after turning on the rotational spindle drives (4) and displacing the layout mechanism (10).

To obtain the leads and the tap-offs, the actuator 17 is turned on and the lever 16 is moved when the electromotive magnet 18 is turned to the far right position. Then turn off the electromagnet 18, and the asterisk takes a position under the windable wire. The actuator 17 is turned on to reverse rotation, the lever 16 moves from the extreme right to the extreme left position, while meeting the wire in its path, carries it along with it, forming a retraction loop (Fig. 7). Then the lever 16 is moved by the electromagnet 18 along the spindle to its extreme rear position. The retraction loop is thrown onto the hook 25 of the twisting mechanism (fig. 7). Then, the actuator 27 is turned on, which transmits the rotation to the hook and twists the retraction loop (Fig. 8). By reducing the length of the loop when twisting, the hook moves somewhat toward the coil. After a predetermined number of twist turns counted by a sensor (not shown), an electromagnet 28 is turned on, which by means of a lever moves the hook 25 along the axis in the direction of the winding coil. The loop is off the hook. The electromagnet 28 is then turned off, and the hook spring 26 returns to its original position.

The formation of the final output occurs in the following sequence. When the lever 16 is turned off, the electromagnet 18 moves from the leftmost position in the winding plane to the rightmost position; it pulls the wire going from the reel to the coil. At the end of the movement, the wire is inserted with an asterisk 21 into the clamp 33, the electromagnet 34 is turned off. On the coil, the end of the wire is secured by an adhesive joint similar to the initial coil lead. Next, the wire is cut with scissors 37. The lever 16 returns to its original position (Fig. 2).

For winding a wire of a different diameter, an actuator 31 is switched on, which moves the carriage with clamps until the axis of the outer wire is flush with the axis of the sprocket. At the end of the winding of all windings, the coil is automatically released from the collet and removed from the spindle.

Thus, the machine provides the winding of complex electric coils with any number of windings from wires of different diameters.
