Robotic spraying process is an automated coating technology widely used in automobile manufacturing, aerospace, home appliance manufacturing and other industries. It uses robots to accurately control the position, angle, speed and other parameters of the spray gun to achieve high-quality and efficient spraying operations. The following is a detailed introduction to the process and key technical points of the robotic spraying process:
1. Preparation stage
• Parts cleaning: Clean the parts to be sprayed to remove impurities such as oil, dust and other impurities on the surface.
• Pretreatment: According to the requirements of the coating, the parts are pretreated as necessary, such as phosphating treatment, chemical conversion film treatment, etc., to improve the adhesion of the coating.
2. Paint mixing
• Paint selection: Select the appropriate paint according to the material and purpose of the spray object.
• Paint mixing: Mix the paint and diluent in the specified proportion to ensure that the viscosity and fluidity of the paint meet the spraying requirements.
3. Preparation before spraying
• Robot programming: Set the robot's spraying path, speed, spray gun angle and other parameters through programming.
• Spray gun adjustment: adjust the spray gun's pressure, flow and other parameters according to the coating characteristics and spraying requirements.
• Test spraying: perform test spraying and adjust the parameters until satisfactory coating quality is obtained.
4. Spraying process
• Robot spraying: the robot sprays according to the preset program to ensure uniform coverage of the entire spraying surface.
• Coating thickness control: control the coating thickness by adjusting the spray gun distance, spraying speed and other parameters to meet quality requirements.
5. Drying and curing
• Natural drying: for some coatings, they can be cured by natural drying after spraying.
• Baking and curing: for coatings that require high temperature curing, they need to be placed in a drying room for baking after spraying to speed up the curing process.
6. Inspection
• Appearance inspection: visually inspect the gloss, flatness, color uniformity, etc. of the coating.
• Performance testing: perform performance tests such as coating hardness, adhesion, corrosion resistance, etc. as needed.
7.Key technical points
• Spraying path planning: a reasonable spraying path can improve spraying efficiency and reduce paint waste.
• Spraying parameter control: including precise control of spray gun distance, spray speed, nozzle pressure and other parameters, which directly affect the coating quality.
• Paint viscosity management: Too high or too low paint viscosity will affect the spraying effect, which needs to be adjusted according to the actual situation.
• Spraying environment control: Keep the temperature and humidity of the spraying workshop appropriate to avoid dust pollution.
Through the control of the above processes and technical points, the robot spraying process can achieve efficient, precise and consistent coating effects, greatly improving production efficiency and product quality.
