Device and method for assembling photo-thermal back plate

The invention relates to the field of optical device mounting devices, in particular to a photo-thermal back plate assembling device and method.When the photo-thermal back plate assembling device works, the device is moved to the position where assembling needs to be conducted through moving wheels, then the position of a base is fixed through a stabilizer, and then a photo-thermal back frame and a main shaft metal frame are placed on an explorator; the photo-thermal back frame and the main shaft metal frame are positioned through a photoelectric positioner mounted on the positioning block; after positioning, a clamping oil cylinder is started to drive a clamping plate to clamp the photo-thermal back frame and the main shaft metal frame; then a plurality of stamping hydraulic cylinders are started in sequence, and the Stokes riveting male dies are driven to be close to the corresponding Stokes riveting female dies on the explorator for riveting; and after riveting is completed, the clamping oil cylinder is lo
