The invention belongs to spraying equipment, and provides spraying equipment for
LED display screens without board edges. The spraying equipment comprises a transmission gear, a conveying device, a spraying device, an air draft device, a
drying device and a
control system. The transmission gear and the various devices can harmoniously run under the control of the
control system, the transmission gear comprises two parallel transmission chains, each transmission chain comprises a plurality of inner chain sheets, outer chain sheets, hinge pins and rolling shafts, chain teeth are arranged on the outer sides, which are close to the to-be-painted
LED display screens without the board edges, of the outer chain sheets of the various transmission chains, and two ends of each to-be-painted
LED display screen without the board edges are respectively supported by the various corresponding chain teeth on the two transmission chains. The spraying equipment has the advantages that circuit boards can be ejected and transported by the aid of the chain teeth, and accordingly the painting efficiency can be improved by 30%; the LED display screens can be painted by the aid of the spraying device, accordingly, the painting quality can be greatly improved, and damp-proof,
mildew-proof and dustproof paint can be saved by 20%; the paint can be sprayed on the LED display screens without auxiliary jigs, and accordingly the spraying equipment is low in production and material costs.
