Automatic painting equipment is a device that can automatically complete painting operations and plays a key role in many fields such as industrial production.
Reciprocating automatic spray painting equipment
Working principle: By using a robotic arm or spray gun to move back and forth on a set track, the painting of the workpiece can be achieved. This movement method can ensure that the surface of the workpiece can be evenly painted within a certain range.
Applicable scenarios: Suitable for workpieces with regular shapes and large flat areas, such as wooden boards, metal sheets, etc. For example, in furniture production, for large areas of tabletops, cabinet doors, and other components, reciprocating automatic painting equipment can efficiently perform painting operations, ensuring the surface flatness and color uniformity.
Rotating automatic painting equipment
Working principle: The workpiece is fixed on a rotating platform, and the spray gun is fixed in one position. When the workpiece rotates, the spray gun sprays paint on it. This method can evenly distribute the paint on the surface of the rotating workpiece.
Applicable scenarios: Suitable for workpieces with rotating body shapes, such as cylindrical metal pipes, plastic pipes, etc. Taking the shaft parts in automotive components as an example, the rotary automatic paint spraying equipment can effectively spray paint on them, ensuring that the circumferential surface is fully covered.
Robot automatic painting equipment
Working principle: Based on robot technology, through pre programming, the robotic arm of the robot can flexibly control parameters such as the position, angle, and spray amount of the spray gun, and can accurately spray paint according to the complex shape of the workpiece.
Applicable scenarios: Suitable for workpieces with complex and irregular shapes, such as car bodies, sculptures, etc. For example, in automobile manufacturing, robot automatic painting equipment can accurately paint every corner and curved part of the car body, and can quickly adjust the painting strategy according to the design requirements of different car models.
Spray gun system
Spray gun: It is a key component that atomizes and sprays paint onto the surface of the workpiece. There are various types of spray guns, such as air spray guns, airless spray guns, electrostatic spray guns, etc. Air spray gun uses compressed air to atomize paint, with good atomization effect, suitable for fine spray painting; Airless spray gun is used to extrude and atomize paint under high pressure, with fast spraying speed and large flow rate, suitable for large-area painting; Electrostatic spray gun utilizes the principle of electrostatic adsorption to make paint particles charged and better adhere to the surface of conductive workpieces, thereby improving paint utilization and adhesion.
Paint supply device: Its main function is to provide a stable supply of paint for the spray gun. It includes paint pumps, paint filters, paint pipelines, etc. The paint pump can extract paint from the storage container and transport it to the spray gun, the paint filter can remove impurities from the paint, prevent clogging of the spray gun, and the paint pipeline connects various components to ensure smooth transfer of paint.
Spray gun controller: It can accurately control various parameters of the spray gun. For example, it can adjust spray pressure, spray speed, spray angle, and paint flow rate. By controlling these parameters, different painting effects can be achieved to meet the painting needs of various workpieces.
conveying system
Function: Responsible for transporting workpieces to the painting area and transporting them away after painting is completed. There are various types of conveyor systems, such as suspended conveyor chains, ground rail conveyor chains, belt conveyors, etc.
For example, suspended conveyor chains are usually used for large workpieces or mass production. On the automobile production line, the car body passes through various painting stations in sequence through a suspended conveyor chain, which can fully utilize space while ensuring the stability of the workpiece during transportation. The ground rail conveyor chain is suitable for heavier workpieces and can provide more stable support.
Ventilation system
Function: During the painting process, the ventilation system is mainly used to exhaust paint mist and harmful gases, while introducing fresh air. A good ventilation system can improve the working environment, reduce the harm of paint mist to the health of operators, and facilitate the drying of paint.
Composition: It includes fans, ventilation ducts, air filters, etc. The fan is the power source of the ventilation system, which discharges paint mist and harmful gases outdoors through ventilation ducts or after purification treatment before discharge. Air filters can filter the fresh air entering the painting area, remove dust and other impurities, and ensure the quality of painting.
Control system
Function: The control system is the brain of the automatic painting equipment, which can control and monitor the entire painting process. It can set and adjust various parameters of spray painting equipment, such as spray painting speed, spray gun angle, ventilation volume, etc. At the same time, it can also monitor the operating status of the equipment, detect faults in a timely manner, and take corresponding measures.
Implementation method: Generally achieved through programmable logic controller (PLC) or computer control system. Operators can input commands through the operation panel or touch screen to operate and manage the device.
Improve the quality of paint spraying
Uniformity: Automatic painting equipment can accurately control painting parameters, making the distribution of paint on the surface of the workpiece more uniform. Compared to manual painting, it can effectively avoid problems such as uneven paint thickness and sagging. For example, in the painting process of electronic product casings, automatic painting equipment can ensure that the color and glossiness of each casing remain consistent.
Accuracy: For complex shaped workpieces, automatic painting equipment can better cover every corner and gap of the workpiece through precise programming and flexible spray gun control. In the painting of car bodies, robot automatic painting equipment can accurately paint details such as door handles and rearview mirrors.
Improve production efficiency
Speed: The painting speed of automatic painting equipment is usually much faster than manual painting. It can work continuously, reducing the intermittent time during manual painting process. For example, in the mass production of some small hardware components, automatic painting equipment can significantly improve production speed and meet the needs of large-scale production.
Stability: Due to the automatic painting equipment working according to preset programs and parameters, its production process is more stable. It will not be affected by factors such as the emotions and physical strength of operators like manual painting, thus ensuring the stability and consistency of product quality.
Cost reduction
Labor cost: Reduced reliance on a large number of spray painters and lowered labor costs. Although some technical personnel are required for equipment maintenance and programming, the overall labor cost has been significantly reduced. For example, in a medium-sized spray painting workshop, the use of automatic spray painting equipment may reduce labor costs by 30% to 50%.
Paint cost: Automatic paint spraying equipment can more accurately control the amount of paint used, improve paint utilization, and thereby reduce paint costs. For example, an electrostatic spray gun can use the principle of electrostatic adsorption to better adhere paint to the surface of the workpiece, reduce paint waste, and improve paint utilization by up to 20% -30%.
