Photosensitive element mounting device and photosensitive element mounting method

The invention discloses a photosensitive element mounting device and a photosensitive element mounting method, and belongs to the field of mounting equipment. The photosensitive element mounting device comprises a first supporting plate, a second supporting plate, three elastic telescopic rods and a plane adjusting assembly, the plane adjusting assembly is located on the second supporting plate and movably connected with the second supporting plate. One end of the elastic telescopic rod is movably connected with the first supporting plate, and the other end is movably connected with the second supporting plate. The three elastic telescopic rods of the photosensitive element mounting device provided by the invention have an elastic telescopic function, and the second supporting plate can change the posture under the action of the target surface to adapt to the posture of the target surface, so that the adjustment process of each structure in the photosensitive element mounting device is reduced; the photosensi
