Industry pain point: The development constraints of traditional furniture spray painting technology

For a long time, the furniture painting process has been highly dependent on manual operation, and many inherent drawbacks have seriously constrained the high-quality development of the industry, mainly reflected in the following three dimensions:

Firstly, the production efficiency is low and the production capacity is limited. Due to factors such as physiological limits and fatigue, manual painting cannot achieve continuous operation, and the daily spraying volume of a single production line is generally low.

Secondly, the spraying quality is unstable and the defect rate is relatively high. Furniture workpieces often have complex curved surfaces, corner gaps, and other structural difficulties. The uniformity of manual painting is difficult to guarantee, and defects such as color difference, sagging, orange peel, and missed spraying are prone to occur. The emergence of these problems is directly related to the proficiency, operational techniques, and even emotional state of workers, resulting in significant fluctuations in product quality and high customer complaint rates.

Thirdly, the cost is high and the environmental and safety risks are prominent. On the one hand, labor costs continue to rise, and the training period for a skilled spray painter is long, leading to increasing pressure on labor costs; On the other hand, the utilization rate of manually sprayed paint is only about 68%, and a large amount of paint is wasted due to overspray, further pushing up raw material costs. More importantly, the VOCs (volatile organic compounds) and paint mist dust generated during the spray painting process pose a serious threat to workers' health, with a high risk of occupational diseases. At the same time, they do not comply with increasingly strict environmental regulations, and companies face high environmental management costs and compliance pressures.

Integrated solution for spray painting of industrial robot chairs

This plan aims to address the pain points of low manual operation efficiency, poor coating uniformity, excessive VOC emissions, and high safety risks in the spraying process of chairs (including solid wood chairs, leisure chairs, office chairs, etc.). Based on the advantages of precise control and flexible operation of industrial robots, a "pretreatment intelligent spraying post-treatment" full process automation system is constructed to achieve the core goals of stable coating quality, improved production efficiency, environmental compliance standards, and comprehensive cost optimization.

Solution

One is the highly flexible robotic arm body. The mainstream adopts a six axis spraying robot, which has multi degree of freedom movement capability and a repeat positioning accuracy of up to 0.05mm. It can accurately fit the trajectory requirements of complex curved surfaces of furniture and achieve blind spot spraying.

The second is the efficient and environmentally friendly spraying execution module. Equipped with a high-precision atomizing spray gun, the fine atomization of the coating is achieved by optimizing the spray gun structure and airflow control, greatly improving the smoothness of the coating.

The third is a closed spray booth designed with fully enclosed negative pressure, which is equipped with a built-in guide plate and paint mist collection device

Customer Case

A high-end furniture manufacturer

Pain points: The efficiency of manually spraying chairs is low, there is a large error in thinning after coating, and the paint loss is high

Solution: Build a spraying production line consisting of 4 Boming spraying robots.

Result: A spraying robot requires 3 to 4 manual workers, with a coating thickness uniformity error of ≤± 0.03mm, and no defects such as missed spraying or sagging. The coating loss of a single chair is reduced by 30%, improving production efficiency and reducing production costs.
