one

A device comprising a rotary table with assembly heads and a drive mechanism is known.

The purpose of the invention is to improve the performance of the device.

This is achieved by the fact that the device is equipped with a mechanism for transporting and cleaning mandrel-satellites, made in form with connected free ends to the working heads of a hollow tube curved along an arc of a circle, the middle part of the tube being grasped by a glue-containing reservoir, has brushes arranged in a spiral.

FIG. 1 depicts a Pyluautomatng device with parazod-em; in fig. 2 a semi-automatic device, top view with numbers of the positions of the location of operations and working heads (heads, working bodies of which are located along the axis of the diffusers, conventionally not shown); n FIG. 3-10 are schematic diagrams of working heads (the letters indicated in circles correspond to the sequence of operations and pa3vieiueH iro;

The working mechanisms in FIG. 2 regarding processed products).

The semiautomatic device contains a bed 1, an electrical equipment block, a camshaft 3 with a cam block, a movable disk with diffusers 5, a fixed table 6, a mechanism for manufacturing a voice coil frame and assembling them; with a diffuser, which includes the device 7, the rod 8. A semi-automatic drive (Fig. 1) consists of an I8 electric motor 9, a reducer 1O, a system of 11 gears, a single turn coupling 12 with a reel 13, a Maltese cross 14, rigidly connected with a disk 4, . the latch 15, controlled by the microwire switch 16.

On disk 4 opposite each mandrel with diffusers, 5 there are located mechanisms for fixing diffusers (Fig. 3} in the form of swinging subjoint levers 17 interacting with a cam 18 rigidly connected to a non-adjustable table 6. The stationary table is intended for use of working heads .

The mechanism for manufacturing the voice coil frame and assembling them with a diffuser (FIG. 1) includes a device 7 for forming a voice coil frame, a rod 8 for feeding the frame into the neck of the diffuser and a dispenser 19 with a valve 20 for supplying solvent adhesive to the neck D1 | Fig. 2). The device 21 for transporting, cleaning, and washing the mandrels of the satellites (Fig. 4) is made of a lever pusher 22, a tube 23, a reservoir 24 and hair rods 2 and is located between the positions l and c. The device for applying glue (Fig. 5) consists of an electric motor 26, a microswitch 27 from shaft 3, a conic gear 28, tanks 29 and 30 with a reserve of handles, a pair of gear wheels 31 and a wetted roller 32. The motor is mounted Two times for applying glue to positions g and e, the Wiper head (Fig. 6) contains a reel 33, a hollow spindle 34, a spreader 35, an electric motor 36, a single-turn coupling 37 with a lever transmission 38 and is located at the position of the e. Stripping unit ( Fig. 7) are designed to remove insulation from the jumper. P wire From the output ends of the coils, it consists of an electric motor 39, a carriage 40 of returning the g-translational motion of the node udol wire and abrasive wheels 41 and is located between positions g and 3, the device for fluxing the stripped sections of wire (Fig. 8) have baths 42 with a flux, flags 43 with hooks attached to them, actuators 44, baths and lancers 45, flags are located behind position 3 and position K. Kontakt) hollow (Fig. 9), provided for podgud ;: electric current, which passes through; and- t through the winding of the sound Xschtushkp in the first (, her day, consists of KOHTfihTDh in (I p () th drive 4 contacts and i.icni) ni) / K (on the position and. The device rpar (-hkch and discharge ports of the P wire (Fig. 10).: Knives 48 and 49 and 5 the VD drive are operated by a knife and installed between the positions to and L. The floor automatic operating device is as follows o6f), i3Oh .. At the position (fig. 2), the diffuser 5 is mounted on the mandrel. When the electromagnet of the single-turn clutch 12 is activated, the rotation from the electric motor 9 through the gearbox 10 is transmitted in two directions - to the reel 13 of the Maltese cross 14, through the system of 11 gears to the spreading shaft 3 with the cam block for controlling the working heads and the shaft 3, to the skeleton device of the voice trap. The Maltese cross unrolls the disc 4 mounted on the mandrels with by diffusers 5 by one position (according to Fig. 2 a 0 °). During the turn of the disc, levers 17 (Fig. 3) exit OUT contact with the fixed cam 18 and press the diffuser. After turning the disc, it engages the fixture 15, which is turned off at the end of the cycle by the microswitch 16. The subsequent execution of all operations is carried out in parallel for one revolution of the camshaft 3. When the camshaft of the device 7 (Fig. 1) is turned, the sound coil carcass is performed as follows: feeding paper stock from the reserve for the length necessary to form the carcass; cut the workpiece and wrapping it around the stem 8; feed the core of the voice coil frame into the diffuser cheek. Glue is pre-applied and dried on the diffuser and on the frame of the voice coil. While the scooter is in the extreme upper position, the dispenser 19 with the solvent glue receives a forward movement downwards. In the lower position, the valve 2O opens onto the cheek of the diffuser and solvent is supplied, after which the dispenser 19 and UITOK 8 are reset. Due to the fact that the frame of the sound coil is not rigid, to perform subsequent operations, a technical mandrel-satellite is inserted into the cheek of the diffuser at the position in (Fig. 2 and 4) instead of the pin 8 (Fig. 1), which follows the moving system from the position at to position l. At the l position, the lever pusher 22 pushes the mandrel into the tube 23. Since the tube is completely filled with satellite mandrels, when the mandrel is pushed out at the l position, the newly fitted diffuser at the in position enters its mandrel. Thus, a closed cycle of the movement of the satellite mandrels is carried out, 1-- 1 In order to remove the glue that fell on the mandrels during the manufacture of the mobile sys- tem, in the lower part of the tube 23 they are passed through the reservoir 24 with solvent and hair Brushes 25. In order to replace the contaminated solvent, drain and filler holes are provided, which are closed by plugs. At position r, glue is applied to the frame of the voice coil. From shaft 3 via micro-off. The reader 27 turns on an electric motor 26, which transmits rotation through a bevel gear 1 to 28 tanks 29 and 30 with a margin of -to. A pair of gears 31 imparts a rotational movement to the roller 32, which, rolling on the surface of the framework, applies a layer of glue. At the next position d, the voice coil is wound onto the frame (Fig. 6). The electric motor 36 is constantly switched on. When coupled through the lever gear 38 from the cam shaft 3 of the single-turn clutch 37, the rotation from the electric motor 36 is transmitted to the hollow spindle 34 with the reel 33 and the worm to the splitter 35, which rotates the worm wheel, the symmetric spreading cam and the cam of the lever system of the electric motor 36. From the spreading cam the reciprocating movement of the hollow sprndel 34 with the reel 33 is reported. Upon completion of one turn of the worm gear one lever gear 38 using the transfer cam disengages the gear coupling 37. and the winding stops After winding the voice coil at position e, glue is reapplied to the winding of the voice coil (Fig. 4). Starting from position d (winding) to position l (cutting), the voice coils of the moving systems are interconnected by jumpers from the winding wire, which are processed with in subsequent operations. Between the positions and z, the jumpers of the P wire are insulated from the insulation (Figs. 2 and 7) with abrasive wheels 41 rotating from the 3G motor and moving along the wire from the cams 40 of the shaft 3. In order to prevent oxidation , the cleaned sections of the wire in the place of the further desoldering are fluxed (Figs. 2 and 8). Reremake P actuator 44 guides the bath 42 with the flux, after which the lever actuator 45 raises the flags 43, the sponges of which touch the wire and are moistened with its flux. On the position and to the stripped sections of the wire with the lever arm: 47 podiks tsp contacts 46. Between the positions of the k and l, carried out by TCP, cut the jumper wires of the slot. The knives 40 and 48 are driven by the cams of the shaft 3 through the drive 50 of the knives to the jumper P and the re-cutter. In position l, a technological mandrel-companion is pushed out. When moving from position l to position, the assembled mover is released from the levers 17, and the finished product is removed at position m. .
