Problems solved by technology

[0004] Aiming at the problems existing in the prior art, such as large physical harm to students, large evaluation errors, and test blind spots, the present invention provides a paint-spraying piece for spray-painting teaching, a paint-spraying device and a teaching method. , a layer of color-changing silica gel particles evenly distributed on the surface of the spray paint receptor is attached, and the paint sprayed from the spray gun is replaced by water. Discoloration is used to evaluate the uniformity of spray paint. Water spray is used in the whole process, and the evaluation standard adopts the principle of silica gel discoloration when it encounters water. The effect is intuitive and accurate, and no blind spot detection is realized.

Abstract

The invention discloses a paint-spraying piece, a paint-spraying device and a teaching method for spray-painting teaching, which belong to the field of paint-spraying teaching, and comprise a paint-spraying receptor and a discoloration layer attached to one side of the paint-spraying receptor. The spray gun is aimed at the color-changing layer on the painted part and sprays water evenly, and the CCD camera is used to take pictures of the color-changing layer, and the image recognition is used to accurately process the color effect after spraying, to obtain the objective results of the painting effect, and to record the learning process of students. The beneficial effects of the present invention are: utilizing the characteristic of discoloration of color-changing silica gel particles in contact with water, a layer of color-changing layer uniformly distributed with color-changing silica gel particles is attached to the surface of the paint spraying receptor, and the paint sprayed from the spray gun is replaced by water, according to the discoloration of the color-changing silica gel particles The uniformity of spray paint is evaluated according to the situation. Water spray is used in the whole process, and the evaluation standard adopts the principle of silica gel discoloration when it encounters water. The effect is intuitive and accurate, and no blind spot detection is realized.

Description

technical field [0001] The invention relates to the field of painting teaching, in particular to a painting piece for painting teaching, a painting device and a teaching method. Background technique [0002] The traditional teaching and training of spray painting is mainly through the movement of the spray gun by the students, and the paint is sprayed out by the spray gun. The students spray the painted parts by adjusting the speed of the moving spray gun and the swing angle of the spray gun. And the student needs long-term spraying training to train excellent spraying technique, like this, will make the consumption of paint and parts to be sprayed increase, and the cost of spraying teaching is high, and, the pungent smell that paint has, also will have a strong impact on students of good health. [0003] Changing the teaching method of painting, especially using other materials instead of paint is an improved method in the teaching and training of painting, which can achie...
