Description

Technical Field

[0001] The present invention relates to the field of Bluetooth headset production, and in particular to a Bluetooth headset assembly auxiliary system. Background Art

[0002] The last step in the production of Bluetooth headsets is assembly. The headset motherboard, tactile copper foil, dustproof net, magnet, battery pack, speaker and tail plug are assembled, and then the ear cover is covered to complete the assembly. After assembly, it is sent to the quality inspection area for final inspection and then packed. However, since the parts of the entire assembly process are irregular and very small, we currently use manual assembly. That is, the worker holds the headset shell, inserts the dustproof net and tactile copper foil first, and then inserts the magnet and glues it. This series of processes is cumbersome to operate with both hands, so the assembly efficiency is low. Therefore, based on the manual assembly of workers, we have designed an auxiliary equipment to assist in assembly. Summary of the Invention

[0028] The operator sits at the assembly station 2. On both sides of the earphone shell feeding conveyor belt 1 in front of his station are support platforms 15 with both hands. The worker holds tweezers and glue in his left and right hands respectively to operate. Since some small parts are not suitable for conveyor belt transmission, dustproof nets, magnets and touch plates are placed on the support platform 15. During installation, according to the installation of different equipment, when installing the magnet in the magnet slot 621, since it is at the mouth of the earphone shell, the earphone shell does not need to be swung at an angle, so the magnet can be injected with glue to be installed vertically. In order to facilitate the installation of the magnet, the earphone carrier 11 is embedded with magnets in the position corresponding to the magnet slot 621, which can play a role in quick installation. When it is necessary to install the dustproof net and the touch plate in the earphone hole 622 and the touch adjustment part 611 respectively, since they are close to the inside, the auxiliary rotating part 5 can be controlled to drive the earphone carrier 11 and the earphone shell to rotate to a certain angle and then install them.
