Abstract

The invention relates to a rapid pulling device for voice coil gauges of a loudspeaker. A device frame is arranged above a belt conveying line in a crossing manner; a displacement cylinder in a displacement mechanism is mounted at the top of the device frame, and a horizontal slider is connected with a piston rod of the displacement cylinder; a longitudinal cylinder in a pulling mechanism is connected to the horizontal slider, a longitudinal slider is connected with a piston rod of the longitudinal cylinder, a pneumatic gripper cylinder is connected to the longitudinal slider, and a pneumatic gripper is mounted at the piston rod end of the pneumatic gripper cylinder; a horizontal cylinder in an ejection mechanism is mounted on one side of the bottom of the device frame, and the piston rod end of the horizontal cylinder faces the belt conveying line and is connected with an ejection groove; a locating plate is mounted on the other side of the bottom of the device frame and is opposite to the front surface of the ejection groove; a longitudinal blocking cylinder in a blocking mechanism is mounted on one side of the bottom of the device frame, and the piston rod end of the longitudinal blocking cylinder is connected with a brake lining; a blanking groove is formed beside the pulling mechanism. The device can rapidly and accurately pull the voice coil gauges, the working difficulty and the labor intensity are reduced, the assembling qualification rate is increased, and the production efficiency is improved.

Description

technical field

[0001] The invention relates to a device for rapidly extracting sound gauges of loudspeakers, belonging to the technical field of loudspeaker assembly. Background technique

[0002] As a sounding body, the speaker must be tightly combined with each other, otherwise the speaker will have abnormal sound or even be unusable. The installation of each component of the loudspeaker requires accurate installation position and firm combination of components. In particular, the voice coil must be kept suspended in the inner magnetic gap (composed of U iron, magnet, and pole core) or the outer magnetic gap (composed of T iron, magnet, and upper splint).

[0003] The current voice coil assembly process generally uses a special annular tool such as a sound gauge for positioning. First, the voice coil is installed on the outer wall of the sound gauge, and then the sound gauge with the voice coil installed is inserted into the magnetic gap, and the speaker is positioned. ...
