The invention belongs to the field of production of sports goods, and particularly relates to an anti-cracking coating method of wood sheets of bars. The anti-cracking coating method of the wood sheets of the bars comprises the steps that roughing treatment is conducted on the surface of a bar core; the surface of the bar core is coated with an adhesive film; a reinforcing material strap is attached to the surface of a wood sheet in the transverse direction; the bar core with the adhesive film is coated with the wood sheet and fixed through a fixing strap in a spiral winding mode when coating is conducted; the fixed bar core is packed with a vacuum bag and put in a drying oven, the vacuum bag is vacuumized, and heating curing is conducted simultaneously. According to the anti-cracking coating method of the wood sheets of the bars, the defects that the wood sheets are cracked and scraped in the coating process of uneven bar products, and in the use process, the surfaces of the wood sheets crack and burrs occur are overcome. The method can improve the anti-cracking performance of the wood sheets in the coating process, therefore, the designed wood sheet thickness is increased, and the service life of the product is prolonged. When 100 thousand times of bending fatigue tests, damp and hot tests and salt spray tests are conducted on the bar products produced through the method, it is proved that cracking of the surfaces of the wood sheets does not occur.
