[0003] However, items that have not been left to touch for longer than the time after painting are not only likely to leave fingerprints due to finger touch, but also stick to dust or particles in the air, or even the hair of the operator. Therefore, the existing painting methods When the painted product is taken out and left to stand, it is very easy to cause defects due to dust, particles in the air or operator hair.
[0004] In addition, general paints have high viscosity and poor fluidity, which is unfavorable for painting operations. Therefore, existing paints need to be diluted with volatile solvents to improve fluidity and facilitate painting operations.
However, depending on the type of solvent and the mixing ratio, as well as the difference in the standing temperature and the length of time, the solvent mixed in the paint may not be completely volatilized before step 13, but it will not evaporate from the paint until it is baked. Volatilized, so it will generate air bubbles on the surface and become a defective product

Embodiment Construction
[0020] The present invention will be described in detail below with reference to the drawings and embodiments.
[0021] Refer to figure 2 , The preferred embodiment of the paint device for the fiber reinforced shell of the present invention includes a pre-processing unit 21, a conveying unit 22 corresponding to the pre-processing unit 21, and a pre-heating unit spaced apart from the pre-processing unit 21 23. A first spraying unit 24 spaced apart from the preheating unit 23, and a second spraying unit 25 spaced apart from the first spraying unit 24. In this preferred embodiment, the pre-processing unit 21 is used to remove dust and static electricity on the surface of the fiber reinforced shell 200, and the pre-heating unit 23 is an infrared heating furnace.
[0022] The conveying unit 22 includes a conveying belt 221, a casing 222 corresponding to the conveying belt 221, and a gas filter mechanism 223. The conveying belt 221 cooperates with the casing 222 to define a connection b...

Provided are a painting method and device of a fiber strengthening outer shell. The painting method comprises the following steps that (A) the fiber strengthening outer shell is heated to a preheating temperature; (B) priming paint is sprayed on the fiber strengthening outer shell; and (C) the fiber strengthening outer shell is subjected to baking, so that the priming paint is finalized. The painting device corresponding to the painting method comprises a conveying unit, a preheating unit and a first spraying unit. The fiber strengthening outer shell is heated to the preheating temperature, then the priming paint is sprayed, a solvent in the priming paint can be volatilized quickly, bubbles generated during baking can be avoided, taking out and standing are of no need, staining of dust or particles or hair of an operator in air is avoided, flaws are effectively avoided, and accordingly yield and productivity are improved.
Description
Technical field [0001] The invention relates to a painting method and a painting device, in particular to a painting method and a painting device of a fiber reinforced shell. Background technique [0002] Refer to figure 1 , Is the existing painting method. First, as shown in step 11, spray paint on the object, and then as shown in step 12, let the painted object stand until it is pressed by your finger without leaving fingerprints. Rear. Then, as shown in step 13, bake the items after standing. In this way, one painting operation is completed, and then steps 11 to 13 are repeated several times as required to complete the painting operation of the product. [0003] However, objects that have not been left to stand for longer than the finger touch time after painting are not only easy to leave fingerprints due to finger touch, but also stick to dust or particles in the air, and even the hair of the operator. Therefore, the existing painting method When the painted product is take...
