Integrated dotting type glue dispensing device

The invention relates to an integrated dotting type glue dispensing device which comprises a connecting part (1) and a glue dispensing head (3) connected with the connecting part (1). The front end of the glue dispensing head (3) is a square glue dispensing part (4), the middle of the square glue dispensing part (4) is hollowed out, exhaust holes (6) are formed in the side wall of the square glue dispensing part (4), and protruding steps (5) are arranged on the periphery of the front end of the square glue dispensing part (4); and the size of the square glue dispensing part (4) is matched with the size of a step (9) of an aluminum oxide support (8) so that the protruding steps (5) can dispense soldering paste (10) on the step (9) of the aluminum oxide support (8) at a time. By means of the integrated dotting type glue dispensing device, single soldering paste dispensing and single lens cover plate covering can be realized, so that the working efficiency can be improved, and the air tightness of a lamp bead ca
