Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings.
[0031] Taking the assembly operation of a certain tiny component as an example, its function is to realize the welding of the suspension wire. The size of the suspended filaments is tens of microns, and it is difficult for human eyes to align them. The specific implementation steps of the present invention are described in conjunction with the technical scheme and the accompanying drawings.
[0032] Step 1: Load part A28, place part A28 to be welded on top of part B29, place solder sheet 30 on top of part A28, wherein part A28 is a long and thin suspension wire.
[0033]Step 2: Turn on the industrial camera 9 , the moving unit drives the vision unit to move above the part A28 to be welded, and the distance in the Z direction is controlled at the working distance of the industrial camera 9 . Adjust the coaxial light source 11 and ring light source 12 to make the image...
