First, turn on the power switch of the second motor 27 to drive the second motor 27 to drive the second lead screw 5 to rotate. Cooperating with two sliders 14 and the second slide bar 26, drive the protective cover 2 and the rubber ring 11 to move downward simultaneously until the rubber ring 11 contacts the top of the operating table 1 and deforms. At this time, the metal part is in a sealed environment, avoiding contact between the metal part and the outside air during the glue dispensing process, so that the dust contained in the air cannot fall on the surface of the metal part, improving the connection quality between the metal part and other components. When dispensing glue, turn on the power switches of the first motor 13 and the third motor 33.

When the air passes through the surface of multiple second fins 32, the air is converted into cold air. When the cold air blows towards the surface of the metal part, it can accelerate the curing speed of the glue, reduce the curing time, and improve the work efficiency.
