The utility model relates to the technical field of
mask production lines, and discloses a
mask observation mechanism of a large-size
mask production line, which comprises a blanking
robot and a blanking clamping jaw arranged at the movable end of the blanking
robot, and the blanking clamping jaw is provided with a
camera identification assembly matched with the movable clamping jaw. The camera recognition
assembly is used for recognizing and positioning the position of a Box, an observation table is arranged on one side of the discharging
robot, a vertical plate clamping
assembly is arranged on the observation table, and the vertical plate clamping assembly comprises a pair of vertical beams and a supporting base, the vertical beams can synchronously move face to face or back to back, and the supporting base can move in the vertical direction. When the mask placing device is in
butt joint with an upstream discharging robot, the mask is in a vertical state, the dust
falling risk is small, workers can observe the mask face and the mirror face on the two sides of the mask respectively, manual face turning is not needed, the mask placing precision is greatly improved, the
collision risk is small, the burden of the workers is relieved, and the production efficiency is improved.
