Description

Technical Field

[0001] This invention belongs to the technical field of automatic spraying, and particularly relates to an automatic masking device and masking method for spraying anti-theft doors. Background Technology

[0002] During the automatic spraying process of security doors, areas that are not to be sprayed need to be covered. The current production method involves manually applying masking paper to the door with tape, which cannot guarantee the quality of the masking. The quality of the masking is controlled by the operator, which cannot guarantee the completeness of the masking. In addition, the production volume of security door spraying is huge, and the production cycle is very demanding. Manual masking cannot meet the production needs of manufacturers. The market urgently needs automated production equipment with high production efficiency and stable product quality.

[0003] The industry standard practice is to manually hang the security door on the hanging chain and then manually wrap the surface of the security door with oil paper to cover the areas that do not need to be painted.

[0004] The current production model requires three workers to work together to complete the task at one workstation, which is labor-intensive, labor-intensive and inefficient; when manually pasting the oil paper, it is easy to tear the oil paper, which cannot guarantee the quality of covering.

[0005] Therefore, we propose an automatic masking device and method for spraying anti-theft doors to solve the above problems. Summary of the Invention
