All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1 and fig. 2, an embodiment of the present invention provides a four-piece optical device coupling welding fixture based on power and light spot detection, which includes a base 1, a clamping portion 2 disposed on the base 1 and used for clamping an optical device 8, and an active perturbation platform 3 disposed at a bottom end of the base 1. Meanwhile, the base 1 is also provided with a guide rail 4 and a connecting seat 5, and the connecting seat 5 is arranged on the guide rail 4 in a sliding manner. The clamping part 2 is located at the first end of the connecting seat 5, the second end of the connecting seat 5 is provided with an elastic body 6, and two ends of the elastic body 6 are respectively connected with the connecting seat 5 and the base 1 to form an elastic connection state of the second end of the connecting seat 5 and the base 1. One side of the guide rail 4 is also provided with a grating ruler 7 which is a displacement sensor for recording the sliding distance of the connecting seat 5 along the guide rail 4.
During the flat-fitting process, the elastic body 6 is kept in a compressed state, i.e. an upward elastic force is continuously applied to the connection seat 5. When the clamped optical device 8 (i.e. the whole light emitting assembly-lens) needs to be attached to the upper optical device 9 (i.e. the receiving assembly), the upper optical device 9 is fixedly suspended above the clamped optical device 8 through another clamp, and the lower surface of the upper optical device is gradually attached to the upper surface of the clamped optical device 8 through displacement of the other clamp, so that the pre-attaching and leveling process is completed.
