Finally, the assembled bluetooth headset 200 is taken down, and a new headset body 201 and headset device 202 to be assembled are placed in the headset body, and the automatic operation of assembling the headset device 202 in the headset body 201 can be realized by repeating the above operations.

Compared with the prior art, the automatic bluetooth headset assembling machine 100 of the present invention is used for assembling the headset device 202 in the headset body 201 with a certain curvature, and comprises the first carrier 10, the second carrier 20, the pushing device 30 and the pressing device 40, the headset device 201 and the headset device 202 are respectively fixed by the first carrier 10 and the second carrier 20, the pushing device 30 pushes the headset device 202 in the second carrier 20 towards the direction of inserting into the headset body 201 under the cooperation of the second carrier 20, so that the headset device 202 is pushed to the attaching area inserted in the headset body 201, because the attaching area is located at the arc-shaped inner wall of the headset body 201, the first pressing head 41 of the pressing device 40 can extend into the headset body 201 and press the headset device 202 located in the attaching area along the direction perpendicular to the pressed surface of the headset device 202, so that the pressure sensitive adhesive 300 preset between the headset body 201 and the headset device 202 is activated, thereby achieving the adhesion of the two. The machine is simple in structure, at least one of the earphone body 201 and the earphone device 202 is coated with the pressure-sensitive adhesive before assembly, and then the pressure-sensitive adhesive 300 is activated by pressure to realize adhesion of the earphone body and the earphone device, so that the assembling mode that the glue is firstly aligned and then is dispensed in a limited space in the prior art is improved, the assembly is easier, the processing precision is higher, and the problem that electronic components are polluted due to the fact that the glue is dispensed after alignment assembly can be effectively reduced.
