Compared with the prior art, in the bluetooth headset charging box assembling jig 100 of the invention, because the first positioning device 10, the second positioning device 20 and the industrial camera 30 are linearly arranged, alignment during assembly is facilitated and the moving stroke between the first positioning device 10 and the second positioning device 20 is effectively shortened, when the case 201 is laterally fixed in the first positioning device 10 and the coil 202 is horizontally fixed in the second positioning device 20, only at least one of the first positioning device 10 and the second positioning device 20 needs to make a linear motion close to or far away from the other, the coil 202 can be driven to horizontally extend into the case 201 until the end 2021 and the buckling part 2022 of the coil 202 respectively align to the embedding groove 2011 and the position of the locking part 2012 of the case 201; when at least one of the first positioning device 10 and the second positioning device 20 is combined to move linearly up and down relative to the other, the end 2021 of the coil 202 can be pressed and embedded into the groove 2011, and meanwhile, the buckling part 2022 of the coil 202 is clamped with the locking part 2012 of the case 201, so that the coil 202 and the case 201 can be firmly and accurately assembled in an aligned manner; in addition, in the process of aligning and assembling the coil 202 and the case 201, the industrial camera 30 can perform alignment detection on the assembly of the coil 202 and the case 201, thereby further improving the accuracy and efficiency of assembly. The assembling jig 100 for the charging box of the Bluetooth headset is simple in structure, reasonable in layout and low in manufacturing cost, and effectively improves assembling accuracy and assembling efficiency.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, therefore, the present invention is not limited by the appended claims.
