The pressing element 33 may be square, and when the pressing element 33 is driven to abut against the face casing 2 and fix the face casing 2, the pressure applied by the pressing element 33 to the face casing 2 only limits the movement of the face casing 2 with the bottom casing 1 in the process of driving the bottom casing 1 to move by the fixing fixture 20, so as to ensure that the second adjusting assembly 60 only adjusts the position of the base.

The pressfitting piece 33 can also be set up to the structure of profiling with the face-piece 2, when the pressfitting piece 33 is driven to butt with the face-piece 2 and when fixing the face-piece 2, at this moment, still be equipped with the negative pressure and adsorb the hole on the pressfitting piece 33, at this moment, can use the fixed mode of negative pressure absorption to replace the mode of exerting pressure to the face-piece 2 to realize fixing to the face-piece 2.

When adopting two image acquisition units 40, the axis mutually perpendicular of two image acquisition units 40 sets up to ensure to detect the ascending a plurality of positions of earphone shell week, promote the precision that detects. Providing a basis for subsequent adjustment of the second adjustment assembly 60.

In step S33: when the difference value is greater than the threshold value, the pressing mechanism 30 is driven to descend to fix the face casing 2, and then the second adjusting assembly 60 is driven to drive the fixing jig 20 to move relative to the base 10, so that the bottom casing 1 and the face casing 2 are aligned.

Further, in step S32, the threshold may be a preset value, or may be calculated after measurement, and the threshold is not limited herein.

The alignment between the bottom shell 1 and the face shell 2 is optimally the alignment of the edges of the bottom shell 1 and the face shell 2, i.e. the edges at the connection of the bottom shell 1 and the face shell 2 are the same size. However, since there may be tolerance in the process of machining the bottom case 1 and the face case 2, when the edge size at the connection between the bottom case 1 and the face case 2 is different due to the machining tolerance between the bottom case 1 and the face case 2, the alignment between the bottom case 1 and the face case 2 may be regarded as the alignment between the bottom case 1 and the face case 2 when the step difference values at the respective positions at the connection between the bottom case 1 and the face case 2 are the same. For example, in fig. 4, since the outer diameter of the face case 2 is smaller than the outer diameter of the bottom case 1 by 0.6mm due to the tolerance of the bottom case 1 and the face case 2 during the machining process, the center of the face case 2 is aligned with the center of the bottom case 1, and the segment difference of each position in the circumferential direction is 0.3mm, which is also considered as the alignment of the bottom case 1 with the face case 2.

And acquiring a section difference value according to the image acquired by photographing. When the segment difference value is determined, one of the face shell 2 and the bottom shell 1 is used as a reference. For example, referring to the left diagram in fig. 4, according to the acquired image, the bottom case 1 is used as a reference, wherein in the left side of the headphone case, the outer contours of the front case 2 and the bottom case 1 are aligned, and the segment difference value D1 is equal to 0; in the right side of earphone shell, the outline of face shell 2 has reduced 0.6mm to the inboard than the outline of drain pan 1, and at this moment, the right side section difference value of earphone shell is D2 and equals 0.6mm. At this time, the maximum segment difference of the earphone shell is 0.6mm. At this time, the second adjusting component 60 directly drives the fixing fixture 20 to drive the bottom case 1 to translate 0.3mm to the left side, referring to the schematic diagram of the left side in fig. 4, after the fixing fixture 20 is moved, the difference D1 between the two sides of the earphone shell is equal to D2, so as to align the face shell 2 and the bottom case 1.

It can be understood that, in step S33, when the pressing mechanism 30 is driven to descend to fix the face casing 2, and the pressing element 33 is driven to abut against the face casing 2 and fix the face casing 2, at this time, the pressure applied by the pressing element 33 on the face casing 2 only limits the face casing 2 to move with the bottom casing 1 during the process of driving the bottom casing 1 to move by the fixing fixture 20, so as to ensure that the second adjusting element 60 only adjusts the position of the base. After the position adjustment to drain pan 1 is accomplished, realize the alignment back of earphone shell, elevating component 31 drives the closure 33 again and applys bigger pressure to the face lid to it is fixed with face lid and drain pan 1, in order to accomplish the equipment of earphone shell.

In step S34, the step difference value of the side edge of the aligned earphone shell is detected again, and when the step difference value is greater than the threshold value, the second adjusting assembly is driven repeatedly to drive the fixing jig to move relative to the base until the step difference values of the two sides of the earphone shell are the same. It can be understood that, the step of detecting the aligned segment difference value of the side of the earphone shell by the detection mechanism may be multiple times, and the range of the segment difference value is determined after each detection result, and when the segment difference values of the two sides of the earphone shell are the same, the second adjusting component stops the adjusting step. When the segment difference value is greater than the threshold value, the step of driving the second adjusting component 60 to drive the fixing jig 20 to move relative to the base 10 is repeated until the segment difference values on the two sides of the earphone shell are the same, so as to ensure the alignment accuracy of the earphone shell.

Step S35 is performed after the earphone shell is aligned, and in step S35, the pressing mechanism applies a greater pressure to the front shell than in step S33, so that the front cover and the bottom shell 1 can be firmly pressed to fix the front cover and the bottom shell, thereby completing the assembly of the earphone shell.
