Ultrasonic Spraying Machine Sprays Wearable Devices

Ultrasonic spraying machine sprays wearable devices – Cheersonic

In the current era of deep integration of the Internet of Things, artificial intelligence and biosensing technology, wearable devices have rapidly penetrated into health monitoring, sports and fitness, industrial protection, consumer entertainment and other fields with their core advantages of being light and easy to use, real-time data collection, and fitting the human body, becoming the core carrier connecting people and intelligent terminals. Wearable devices cover various types such as smart bracelets, health monitoring patches, flexible sports equipment, industrial protective wear, AR/VR display glasses, etc. Their core competitiveness focuses on lightweight, flexibility, high stability and biocompatibility. The realization of these properties cannot be achieved without the precision coating of surface functional coatings. With its core advantages of precision atomization, low damage, and high adaptability, Cheersonic ultrasonic spraying machine perfectly meets the spraying needs of various functional layers and flexible substrates of wearable devices, providing core equipment support for large-scale mass production and performance upgrades of wearable devices, helping companies break through process bottlenecks and enhance product competitiveness.

The structural characteristics and application scenarios of wearable devices place extremely stringent requirements on the spraying process. Different from traditional rigid electronic devices, wearable devices mostly use base materials such as flexible textiles, silicone, and flexible polymers. They must have good bending properties, breathability, and skin compatibility. The functional coatings (conductive layer, sensing layer, waterproof and anti-sweat layer, and biocompatible coating) coated on the surface must be ultra-thin, uniform, and have strong adhesion without affecting the flexibility and breathability of the base material. For example, the sensing layer of health monitoring wearable devices needs to be accurately coated to ensure the accuracy of physiological data detection; the waterproof and sweat-proof layer of flexible sports equipment needs to be dense and uniform, suitable for daily sports and complex environment use; the wear-resistant coating of industrial protective wear needs to be tough and durable to ensure long-term stable operation of the equipment. In addition, most wearable devices are miniaturized and lightweight in design, and the coating process needs to avoid coating accumulation and spillage to prevent them from affecting the normal operation and wearing comfort of internal components.

Traditional wearable device spraying processes (air spraying, brushing, spin coating) have many shortcomings and are difficult to adapt to the production needs of high-end products. The particle size of air spray droplets is uneven, and it is easy to produce pinholes and orange peel marks on the surface of flexible substrates, which affects the waterproofness and conductivity of the coating. High-pressure airflow can easily damage the flexible substrate, causing deformation and damage of the substrate. The brushing efficiency is low, the uniformity of the coating is extremely poor, and brush marks are prone to occur, which cannot meet the needs of sensing. Precision coating requirements for layers and conductive layers, and is only suitable for wearable devices with simple structures; spin coating is only suitable for flat rigid substrates and cannot handle curved, flexible, and textile substrates. Material waste is serious, and beading is prone to occur on the edges of the coating, affecting the appearance and use experience of wearable devices. These shortcomings have seriously restricted the development of wearable devices in the direction of flexibility, high precision, and scale.

Cheersonic ultrasonic spraying machine is specially optimized to solve the spraying pain points of wearable devices and relies on high-frequency atomization core technology to completely break the bottleneck of traditional processes. The equipment converts power frequency electricity into 40-150kHz high-frequency electrical signals through an ultrasonic generator, and converts them into high-frequency mechanical vibrations through a piezoelectric ceramic transducer, so that the coating materials (conductive slurry, sensing slurry, waterproofing agent, biocompatible coating liquid, etc.) form uniform mist droplets of 0.1-10 microns. It is gently deposited on the surface of the flexible substrate under the guidance of low-pressure carrier gas. There is no high-pressure impact or high temperature in the entire process, which avoids damage to the flexible substrate and internal components. It also effectively eliminates pinholes, brush marks, accumulation and other defects, forming a high-quality coating with dense uniformity and precise thickness, without affecting the flexibility and breathability of the substrate.

In response to the spraying needs of wearable devices, Cheersonic ultrasonic spraying machines have demonstrated four core advantages, helping to double improve product performance and mass production efficiency. First, the coating accuracy is extremely high, and the coating thickness can be precisely controlled at the nanometer level, with a thickness deviation of ≤±2%, ensuring stable performance of the conductive layer and sensing layer, and improving the data detection accuracy and signal transmission efficiency of wearable devices; second, low-damage coating Coating, low-pressure atomization technology can be adapted to a variety of flexible substrates such as textiles, silicone, and flexible polymers, without damaging the bending and breathability of the substrate, while retaining the biocompatibility of the coating and adapting to skin-contact wearable devices; third, process adaptability Strong, it can take into account the spraying of multiple types of coatings such as conductive layers, sensing layers, waterproof and sweat-proof layers, and is suitable for wearable devices of different sizes and structures, achieving multiple uses in one machine. It also supports automated continuous spraying and adapts to large-scale mass production needs; fourth, the material utilization rate is high, which can reach more than 95%, significantly reducing the consumption of high-value functional coating materials, significantly reducing production costs, and the coating has strong adhesion, excellent wear resistance, waterproof and sweat-proof performance, effectively extending the service life of wearable devices.

At present, Cheersonic ultrasonic spraying machines have been applied on a large scale in the production of wearable devices, covering core scenarios such as health monitoring patches, smart bracelets, flexible sports equipment, industrial protective wear, and AR/VR display glasses, helping companies solve the pain points of traditional spraying processes and achieve product quality upgrades. As a leader in the field of ultrasonic precision spraying, Cheersonic Ultrasonic has been deeply involved in the spraying field of smart wearable devices for many years. It can provide customized spraying solutions, covering equipment selection, process parameter optimization, coating material adaptation and other full-process support, helping customers give full play to the technical advantages of wearable devices. In the future, Cheersonic Ultrasonic will continue to optimize equipment performance, adapt to the needs of wearable devices to upgrade to flexibility, high precision, and multi-function, inject strong impetus into the high-quality development of the smart wearable device industry, and promote the widespread popularization of wearable devices in more professional and consumer scenarios.
