Automatic assembling equipment of magnetic circuit system of loudspeaker

Abstract

The invention relates to automatic assembling equipment of a magnetic circuit system of a loudspeaker. The automatic assembling equipment comprises a bottom plate, wherein a feeding mechanism and a washer and rivet combined mechanism are arranged on the bottom plate; the feeding mechanism comprises a rotary table, clamps and a driver, the rotary table is equally divided in a multi-station mode, the clamps are arranged on the periphery of the rotary table at equal intervals to accumulate and position one end of a rivet cap of each rivet, and the driver drives the rotary table to step intermittently to replace stations; a magnet feeding structure, a T iron feeding structure, a PCB feeding structure and a riveting pressing mechanism are further sequentially arranged on the bottom plate and around the rotary table, the magnet feeding structure, the T iron feeding structure and the PCB feeding structure respectively enable a magnet, T iron and a PCB to be connected to the rivets in a sleeved mode, the riveting pressing mechanism opens a hollow folding edge structure end portion arranged at the other end, away from the rivet cap, of each rivet in a riveted mode, and the mechanisms are controlled by a master control circuit. A rotary table type production mode is adopted, a washer, the magnet, the T iron and the PCB can be assembled and riveted automatically, efficiency is improved because the stations work simultaneously, existing manual operation is replaced, labor cost is lowered, the mechanisms are mechanically controlled to achieve automatic positioning, alignment is accurate, and product consistency is good.

Description

technical field [0001] The invention relates to an automatic assembly device for a loudspeaker magnetic circuit system, in particular to an automatic machine for assembling washers, magnets, T irons, and PCB boards into a magnetic circuit system through rivets during the loudspeaker manufacturing process. Background technique [0002] With the development of loudspeaker technology, the application range of loudspeaker devices is becoming wider and wider. Existing interiors suitable for earphones or earphones are all equipped with a loudspeaker, and the loudspeaker of traditional technology includes a vibration system, a magnetic circuit system and a shell combining the vibration system and the magnetic circuit system. Such as figure 1 As shown, the built-in magnetic circuit system of the loudspeaker is composed of washer 1, magnet 2, T iron 3, PCB board 4 and rivet 5. At present, the assembly of the magnetic circuit system is mainly completed manually. The specific steps ar...
