Enabling precision manufacturing, Dahuan voice coil actuator is launched

According to the "Mid-Year Semiconductor Equipment Forecast Report" by SEMI, the International Semiconductor Industry Association, global total sales of semiconductor manufacturing equipment by original equipment manufacturers are expected to reach a record US$117.5 billion in 2022, a year-on-year increase of 14.7%.

In recent years, with the upgrading of new consumption in the 3C industry and the high prosperity cycle of the semiconductor industry, global wafer factories have continued to expand, driving the equipment to rise, and the demand in mainland China is particularly strong. It is worth noting that most of the packaging production equipment in China has been dependent on imports all year round, and among them, parts and components, which are the key components of semiconductor equipment, are currently the field with serious "neck choke" in China. Its localization penetration rate is low, and there is huge room for domestic substitution.

As a company that focuses on providing precision core motion control components, Dahuan Robotics has launched a series of voice coil actuators, including the VLA series voice coil linear actuators and the VLAR series voice coil linear rotary actuators, in response to the development pain points and market demands of high-end precision manufacturing. It has become the first local company in the industry to achieve stable mass production.

In addition, Dahuan has further filled the gap in the domestic voice coil actuator market with its rich product line and achieved localized production. While broadening the application boundaries of its products, it has effectively helped companies reduce costs and increase efficiency.

Dahuan voice coil actuator is a direct drive motor, which adopts a highly integrated module design. It has the advantages of small size, high precision, fast response speed, precise force control, and long life . At the same time, it can accurately control the force output of the voice coil motor through calibration. With the high-precision encoder , it can directly read back the position information, so it can greatly simplify the system and realize equipment standardization.

At present, Dahuan voice coil actuators have been applied to high-speed pick -and-place, bonding assembly, positioning testing and other typical application scenarios on precision production lines, covering 3C electronics, semiconductors, new energy, packaging and many other fields.

Product Advantages

1. High precision, soft landing, meeting the needs of high force control precision production and assembly

In high-precision positioning, assembly, and testing, there are often high requirements for flexible grasping and fast pick-and-place of small workpieces. Dahuan voice coil actuators use self-developed direct-drive force feedback technology and precision control technology. Its repeatability can reach ±2μm, and its rotational position resolution is 0.005°. It can also achieve intelligent soft landing with a force control accuracy of ±3g, gently contact the workpiece, and achieve zero damage to precision and fragile parts.

2. Compact and thin, enabling matrix installation of products side by side

The smallest volume of the VLA series products is only 80×55×16mm, which is the size of a portable handkerchief. The width is as thin as 16mm, which can enable two or more voice coil products to be installed side by side, easily adapting to the use requirements of narrow spaces in automation equipment. At the same time, it supports multiple installation methods and can flexibly cope with the complex installation environments of various real applications.

3. Multi-directional movement, adjustable parameters, and rapid deployment of various applications

The VLAR series realizes an integrated "vacuum + Z-axis up and down + R-axis rotation" structural design, which can provide precise Z-axis linear + rotational motion at high speed, greatly saving equipment space and cost for customers, and achieving simplification, standardization and lightweight of equipment. In addition, the voice coil actuator can adjust the speed, thrust and position parameters through the control software, set different working modes, and fully meet the industrial scenarios with high-frequency and high-precision requirements.

Product Parameters

Application Examples

Dahuan Robotics has launched the VLA series and VLAR series of voice coil actuators, which are available in two versions: grating and magnetic grating. Upon request, we can also tailor precision motion solutions for your application.

In the factory inspection of electronic products, sensitivity and fatigue tests such as mobile phone/keyboard buttons, screen tests, power switch feel, touch panel pressure detection, etc. are essential links, which require continuous output of constant force for repeated contact testing; and the high precision, high speed and high frequency characteristics of Dahuan voice coil actuators are very suitable for such tests and can effectively improve inspection efficiency.

Semiconductor Body Industry

In the chip packaging process, the fragile properties of the chip PIN, which is easy to break and scratch, greatly limit the process control of vacuum picking and placement operations. The Dahuan voice coil actuator can realize integrated ZR operation and achieve intelligent soft landing based on precise force control without causing damage to the workpiece.

Lithium battery industry

In the lithium battery production process, the Dahuan voice coil actuator sets the corresponding thrust and speed through the program, and then flexibly pushes the battery pack to assemble the battery cells and detect the battery height. The high frequency, high stability and long life of the voice coil actuator can meet the requirements of long-term operation of the production line.

Next, Dahuan Robotics will launch more models of voice coil actuator product series to meet the production needs of more high-end precision manufacturing industries.
