Description

(54) DEVICE FOR ASSEMBLING A DYNAMIC SPEAKER DIFFUSER WITH A SOUND COIL FRAMEWORK

one

The invention can be used in the radio industry of enterprises producing dynamic loudspeakers.

Arrangements for assembling a dynamic diffuser of a dynamic coil with a skeleton of a sound coil are known, comprising a mandrel for fixing the diffuser, a solvent dispenser with glue, mechanism 1, making a voice coil equipped with rollers for feeding the tape, a mechanism for twisting and cutting the tape, containing a knife, and a drive mechanism .

The purpose of the invention is to mechanize the process of assembling a gueam speaker.

The goal is achieved by the fact that the device is equipped with a frame feeding mechanism in the diffuser neck, made in the form of a cam-controlled distribution shaft of a spring-loaded rod, and the metering device is mounted on a carriage kinematically connected to the cu. the camshaft of the drive mechanism, on which the toothed sector is fixed, which is connected by means of a gear transmission with a roller and a belt feed,

and the knife of the trimming mechanism Agents is fixed on the yoke, interacting with one of the camshaft cams.

FIG. 1 shows a general view of the device; in fig. 2 - fundamental decisions of its individual elements.

The device STOSTO..T from the base 1 of the electric motor 2 with the reducer 3, the bevel gear 4, the mandrel 5, onto which the diffuser 6 is mounted, the Ichzavod of the voice coil frame and the dispenser. The mechanism for manufacturing the voice coil cage will hold the reel 7 with the tape 8, the tape drive unit and the rafter head shaft 9 with the tape feed sector 10 attached to the tape feed unit, the cutter cam 11, the frame feed cam 12 and the tape feed unit consists of a conical. gear 1, 4, engaging with the toothed sector 10, gears 15 and 16, and rollers 17 and 18 mounted on the axles to provide the necessary force of contact with the tape through elastic sleeves 19 and 2O (Fig. 2). Knot

wound the knife 21 mounted on the core of the thought -22, which is the spring of the spring 23 contact 1 with the cam 11. The frame feed assembly consists of the stem 24, which is pressed against the cam 12 by the action of the spring 25 via the roller 26 (tape. 2) contains a block 27 with an elastic cushion fixed on it-, a mash 28, a scraper 29 and an AO screw with a flywheel 31. Using a screw 30, the force of the scraper 29 is adjusted to the shock absorber 28. The gear-wheel 13 is coupled with the gear wheel 32, on the same axis with which the cam 33 is attached and the vorshchayushchy elastic p 34, allowing the tape to twist around the stem 24. The dispenser consists of a shaft 35 with a cam 36, a bracket 37 along which the carriage 38 moves, tanks with solvent 39 and 4O, a check valve 41, needles 42, a lever 43, sleeves 44 and rings 45. The tank 39 is intended to replenish the solvent in the tank 4O to a certain level, due to which a uniform flow of glue is carried out. The diffuser is pressed against the mandrel 5 by the clamp 46. The belts in the section from the feed rollers 17 and 18 to the stem 24 (Fig. 2) move along the guides 47-50.

The device works as follows.

From the electric motor 2, through the gearbox 3, rotation is transmitted to the camshaft 9 of the shaft 35 with the cam 36; from the toothed sector 10 through the bevel gear 14, the gears 15 and 16 to the rollers 17 and 18. The rollers 17 and 18 feed the belt 8 from the reel 7 along the guides 47-50 to the roller 34. The cam 11 rotates through a rocking motion rocker 22 knife 21, which ot-, cuts a strip of tape. The length of the strip of tape from the knife 21 to the roller 34 is equal to the length of the circumference of the voice coil frame. Through the gear wheels 13 and 32, the rotation 3 is transmitted to the cam 3, and from there to the roller 34, which spins the ribbon around. The stem 24. To facilitate the conditions, the twist to release of internal stresses in the belt, the latter, in the area from the reel 7 to the feed rollers 17 and 18, is exposed to a scraper 29 made of a sheet of spring material. After twisting the tape, cam 12 lifts the pinch 24 to the extreme upper position and the voice coil frame is fed into the diffuser jaw. From the cam 36, the carriage 38 receives a downward movement. At the approach of the dispenser to the neck of the diffuser, the lever 43 meets the stop fixed on the bracket 37 and opens the check valve 41 through the needle 42. The solvent glue from the tank 40 through the channels in the valve 41 and the sleeve 44 enters the annular gap between the sleeve 44 and the ring 45, and . from there - to the neck of the diffuser. After gluing the frame of the voice coil to the neck of the diffuser, the mechanisms return to their original position ...
