Compared with the prior art, in the Bluetooth earphone charging box assembly jig 100 of the present invention, since the first positioning device 10, the second positioning device 20 and the industrial camera 30 are arranged in a straight line, the alignment during assembly is convenient. And effectively shorten the moving distance between each other, when the casing 201 is laterally fixed in the first positioning device 10, and the coil 202 is horizontally fixed in the second positioning device 20, only the first positioning device 10 and the second positioning device 10. At least one of the two positioning devices 20 moves linearly toward or away from the other, so as to drive the coil 202 to extend into the casing 201 horizontally, until the end 2021 of the coil 202 and the buckling portion 2022 face each other respectively. At the position of the embedding groove 2011 and the locking portion 2012 of the casing 201; in combination with at least one of the first positioning device 10 and the second positioning device 20 can also move up and down linearly relative to the other, the end portion 2021 of the coil 202 Then, the coil 202 can be pressed into the 2011. At the same time, the buckle portion 2022 of the coil 202 and the lock portion 2012 of the casing 201 are snapped together, so that the coil 202 and the casing 201 can be firmly and accurately aligned. In addition, in the process of aligning and assembling the coil 202 and the casing 201, the industrial camera 30 can perform alignment detection on the assembling of the two, thereby further improving the accuracy and efficiency of the assembling. The bluetooth earphone charging box assembling fixture 100 of the utility model has the advantages of simple structure, reasonable layout and low manufacturing cost, which effectively improves the assembling accuracy and the assembling efficiency.

The above disclosures are only the preferred embodiments of the present invention, of course, the scope of the rights of the present invention cannot be limited by this. Therefore, the equivalent changes made according to the scope of the patent application of the present invention are still within the scope of the present invention. .
