Assembly positioning device and system for earphone shell and flat cable

Abstract

The invention provides an assembly positioning device and system for an earphone shell and a flat cable. The assembly positioning device comprises a floating positioning assembly and an assembly driving assembly, wherein the floating positioning assembly comprises a first support frame, a shell floating positioning module and a pressure stabilizing cylinder module; the assembly driving assembly comprises a flat cable positioning module and a driving module, and the driving module is used for driving the flat cable positioning module to assemble the flat cable into the earphone shell; the shell floating positioning module is arranged on the first support frame and can move relative to the first support frame, and the pressure stabilizing cylinder module is used for applying preset constant thrust to the shell floating positioning module, so that the shell floating positioning module abuts against a limiting assembly arranged on the first support frame; and the shell floating positioning module is arranged to move in the direction of assembly pressure when the borne assembly pressure exceeds a pressure threshold value, and the pressure stabilizing cylinder module keeps the preset constant thrust on the shell floating positioning module in the moving process. The assembly pressure can be kept constant, the problem that an assembled product is damaged due to overpressure and the like is solved, and the assembly effect is improved.

Description

technical field [0001] The invention mainly relates to the technical field of earphone assembly, in particular to an assembly and positioning device and system for an earphone shell and a cable. Background technique [0002] Earphone is an audio output device with a wide range of applications and plays an important role in people's daily life. When people listen to music, it can not only effectively block external noise, but also prevent the music played from disturbing other people. As a necessary accessory for smart phones and other digital players, earphones are also being updated day by day, and then become an indispensable necessity for people to enjoy audio-visual multimedia entertainment life. [0003] Correspondingly, the requirements for the assembly equipment of earphones are getting higher and higher. Such as figure 1 Shown is a schematic diagram of the assembly structure of the earphone housing 5 (HSG) and the internal cable 6 (Flex). Combined, and after a pre...

Problems solved by technology

In this assembly process, the earphone shell and the cable are small in size, and the assembly precision is high. The control of the assembly force is very important to ensure the assembly effect. If it is too large, it will damage the earphone shell and cable, or the assembly quality will be uneven and the assembly efficiency will be low due to too small assembly force and unstable pressure, and the assembly effect will not be guaranteed.
