then the lens clamp 22 leaves the lens 02, the lower clamp assembly 1 drives the light emitting device-lens to displace in the horizontal plane, the upper clamp assembly 3 drives the receiving device 03 and the adjusting ring 04 to displace vertically, multi-channel spatial coupling of the light emitting device-lens and the receiving device 03 is started, a power field model is established, power equalization is performed again to confirm the vertical positions of the receiving device 03 and the adjusting ring 04 clamped by the upper clamp assembly 3, after confirmation, the welding device 4 determines the focal length and completes penetration welding of the adjusting ring 04 and the receiving device 03, and the whole of the receiving device-adjusting ring is formed;
then, the light emitting device-lens and the receiving device-adjusting ring are flatly jointed, at the moment, the adjusting ring tightly props against the clamp 33 and is away from the position of the adjusting ring 04, the receiver clamp 32 drives the receiving device-adjusting ring to vertically move downwards, the lower surface of the receiving device 03 is jointed with the upper surface of the lens 02, the light emitting device-lens is gradually flatly jointed with the receiving device-adjusting ring under the coupling action of the lower clamp 12, the angle error of the flat surface is in an allowable range, then the lower clamp assembly 1 drives the light emitting device-lens to move in the horizontal plane, the power coupling and the power balance of the light emitting device-lens and the receiving device-adjusting ring in the plane are completed, the relative horizontal positions of the light emitting device-lens and the receiving device-adjusting ring are confirmed, the welding device carries out lap welding of the light emitting device-lens and the, and completing the whole coupling welding process of the four-piece optical device.

Further, the lower jig moving stage 11 includes a first X-axis rotation stage 111, a first Y-axis rotation stage 112, a first Y-axis displacement stage 113, a first X-axis displacement stage 114, and a first Z-axis rotation stage 115, which are provided in this order from the bottom end of the lower jig 12, and the lower jig 12 is provided on the first X-axis rotation stage 111, and has rotational degrees of freedom about the X-axis, about the Y-axis, and about the Z-axis, and translational degrees of freedom along the Y-axis and along the X-axis. The lower fixture 12 adjusts the inclination angle between the upper surface of the device and the lower surface of another device to complete the flat contact between the upper surface and the lower surface of the device through the cooperation of the first rotating platform 112 around the Y axis and the first rotating platform 111 around the X axis. When the lens 02 and the light emitting device 01 are welded into a whole, the first Y-axis displacement platform 113 and the first X-axis displacement platform 114 drive the lower fixture 12 to horizontally displace, so that the light emitting device-lens and the receiving device 03 are vertically aligned to perform multi-channel spatial coupling of optical power. Wherein the rotation centers of the first rotation platform 112 around the Y axis and the first rotation platform 111 around the X axis just overlap the upper surface of the light emitting device 01, thereby reducing linear displacement compensation at the time of angular displacement adjustment.

When the attaching accuracy of the upper surface of the light emitting device 01 (or the lens 02) and the lower surface of the lens 02 (or the receiving device 03) is higher, the relative displacement variation range of the connection plate 124 should be smaller under the same amplitude of the swing of the base 121. Therefore, the process of leveling is that the base 121 continuously changes its swing (direction and amplitude) under the driving of the first rotating platform 111 around the Y axis and the first rotating platform 112 around the X axis, so that the clamped device continuously performs pre-leveling, and then the displacement variation range of the slider 123 and the connecting plate 124 on the guide rail 122 is detected through the grating ruler 127, when the range is minimum (or less than a preset value), the leveling is qualified, and the precision reaches a preset standard.
