5 Crucial Checks of Electrostatic Painting Troubleshooting

Tutorial

Electrostatic Painting Principle and Composition Electrostatic painting uses the workpiece as the positive electrode(usually grounded). The paint atomization device is the negative electrode which is connected to the negative high voltage power supply. Between is a high-voltage electrostatic field with the workpiece. The paint is squeezed into the nozzle at high speed under compressed air then hits on the nozzle, here it's negatively charged and forms micron-sized atomized particles then spray through the circular outlet of the nozzle. Due to the effect of corona discharge, the paint particles repel each other and further atomize. According to the principle of "opposites attract each other", the negatively charged paint medium forms an embracing effect on the workpiece under the action of the electric field force, along the power line directionally flow to…

Painting Robot Structure Explained

Painting robot, Tutorial

Painting robot is a type of industrial robot which consists of three major parts and six subsystems. The three major parts are: the mechanical body, the sensor and control part. The six subsystems are: drive system, mechanical structure system, perception system, robot-environment interaction system, man-machine interaction system and control system. Following we will provide a detailed introduction over the six subsystems. Drive system of painting robot To make the painting robot run, a transmission device for each wrist(freedom of motion) is installed, that is the drive system. The drive system can be hydraulic, pneumatic or electric, or a comprehensive system combining them. It can be directly driven or indirectly driven through mechanical transmission such as synchronous belts, chain and harmonic gears. Mechanical structure of painting robot Painting robot mechanical structure…

Furniture Automatic Painting Advice

Tutorial

Furniture is a big industry as it's related to each family for every reason. Any furniture will need partial or complete painting treatment in factory either for decoration or surface protection purpose. In general, furniture items are available in full unit or just piece by piece component parts. In order to properly paint these different units we have to implement a suitable machine for each. In the following we will learn on these different pieces and advise a workable painting solution. Flat board The most common piece for furniture production such as cabinet, door and table etc. For such flat pieces, we normally need to paint top surface only or sometimes on the 4 edges. In order to paint the flat board properly, we normally make a horizontal conveyor system…

Spray Coating Technology Future Development View

Tutorial

Spray coating is more and more used in every corner for modern industrial production. If we take a view over the coating history we will see it has been heavily developed with quick iteration. Either the paint or the application technology or the machinery has been improving quickly over the last 30 years. Now standing at the industrial 4.0 entrance we will take a glance view of the next 5-10 years development of spray coating industry. Practicality Or usability, means the possibility of quick and wide application by different industries. With the technology development, any new devloped spraying technique can be quickly applied to real production to win the market. As there're more and more players, everyone will try to give a competitive solution and doing new research. Integration The…

Clean Room Importance for High Quality Coating

Tutorial

For paint shop construction, we will install a variety of robotic devices such as material handling robot, painting robot and other automatic machines to maintain a stable and high efficiency production as much as possible. In fact, the fine rate is not only about how the machine working but also the general workshop consideration. Clean room is a basic but crucial part for high quality coating process. Following we will troubleshoot the most common quality issue for paint spraying system and give guidance how to make a tailored clean room. Fine Rate Investigation In coating plant, the most common issue is dust particles after curing. The dust can not be removed anymore and the finished product will be a defective piece after finishing and just reduce the production fine rate.…

The Difficulty of Automatic Trace Spraying

Tutorial

Automatic trace spraying means the spray gun will spray on loaded objects while they're moving forward on a conveyor system. The painting machine or robot will follow the conveyor speed and complete the spraying before objects move out it's effective working area. When everything setup well, it seems pretty easy. However, things are not always as expected due to various conditions. When we configure a robotic spray painting system, we always need to automate the setup as much as possible regardless the spraying method. But it's not always so easy to make it working as design principle due to technical limitation or the onsite operator skills. In this article we will briefly explain the concept and required technology in order to configure a full automatic trace spraying system by industrial…

VOCs and Control in Automotive Coating Industry

Tutorial

In the coating process, VOCs are mainly produced in the spraying and drying process of the middle coat and top coat over plastic parts finishing(sealing and spraying due to relatively small content of VOCs). The organic waste gas produced by painting has the characteristics of large air volume and medium to low concentration. 1)Paint spray booth: The main harmful component from paint booth exhausting is the organic solvent volatilized during the painting process. The spray booth exhaust volume is large but the total concentration of organic matter is low, generally below 100mg/m3. In addition, the exhaust from paint spray booths often contains a small amount of paint mist that has not been fully treated. Especially in the dry paint filter spray booth, there are more paint mist exhausted. 2)Drying chamber:…

Why Flame Treatment in Paint Spraying?

Tutorial

Flame treatment principle Flame treatment is a widely used process for surface modification of substrates such as plastics, glass and metal foils to improve their adhesion to liquids such as inks, paints, binders and coatings. Plastics used for flamming are thermoplastics and thermosets. When heated, thermoplastics will gradually soften and melt with the increase of temperature, and will become hard after cooling.At the same time, this process is reversible. We generally use surface tension or surface energy to measure the ability of the substrate to adsorb liquids, and if the substrate surface energy is at a high level, the liquid will become more wetted on its surface and have good ductility. Making the liquid more wetted on the substrate is the basis for the substrate to adsorb the liquid. If…

Paint Shop Safety Planning

Tutorial

Spray painting machine is widely used in almost all industries for it's flexible application. Safety is considered more and more due to uprising issues caused by various reasons. Beside furthermore training to improve the safety concept and experience sharing, we also need to avoid potential factors from the initial start such as machine designing and production. Here we have a safety list including both mechanical and electric tactic. Mechanical construction Most part of painting machine construction is mechanical. Although the basic logic and concept is pretty simple, the final presentation can can easily tell the manufacturer's skill and management level. Beside the general functionality, we have to pay attention to each small piece considerring safety such as no sharp edge and corner protection etc. For example after a steel plate…

Full Automatic or Semi Automatic Painting System?

Tutorial

When considerring a painting system for our business, we have numorous selections and could be misguided if we can't indepth evaluate our tailored needs. Ideally, we should make full use of the machine to be a powerful backend of our business improvement. If we select a wrong machine, it's not just about monetary but also a bad affect to our business development. Thus a smart decision is not a single purchase but a tactic to future. How to choose the most suitable painting machine? Regardless the various choice, there're basically two options - full automatic and semi automatic. The only difference is how the process being handled through various mechanical devices such as robot or penumatic guns etc. Following we will indepth introduce the two options and guide how to…
