In modern high-speed automated production lines, multi-station operations impose stringent requirements on the dynamic adjustment of workpiece spacing. From material handling and assembly to inspection and sorting, the spacing between workstations in each process is often inconsistent. Traditional equidistant conveying struggles to match the takt times and layouts of different equipment, resulting in difficulties in line integration, large floor space requirements, and constrained production efficiency. At the same time, high-precision applications such as wafer handling, die bonding, and precision measurement demand highly consistent motion and precise positioning; even the slightest dimensional deviation can result in product scrap. Multi-station variable-pitch mechanisms have emerged, utilizing precise synchronous control to enable multi-station operations with either equal or variable spacing, ensuring consistent motion and operational accuracy, thereby becoming a core component for the efficient operation of automated production lines.

Since its establishment in 2000, Dongguan Xinda Industrial Automation Co., Ltd. has been dedicated to the R&D and manufacturing of precision variable-pitch slides and modules. Its products are based on a meticulously designed synchronous variable-pitch slide mechanism and incorporate high-quality core components, ensuring long-term, efficient, stable, and reliable equipment operation. Its core structure consists of the following components:

Synchronous control driveAdvanced synchronous control technology is employed to enable multi-axis coordination, ensuring uniform speed and consistent spacing across all stations, thereby guaranteeing motion consistency and operational accuracy.
Precision guide rail sliderEquipped with an integrated miniature slide mechanism, it features a compact footprint and lightweight design, enabling flexible variable‑pitch handling operations in confined spaces, significantly enhancing site adaptability and layout flexibility.
Variable-linkage mechanismThe gripper spacing is dynamically adjusted via a cam, linkage, or servo actuator, supporting both equal-pitch and variable-pitch operating modes.
High-quality componentsKey drive components undergo precision machining, assembly, and debugging, with comprehensive quality control throughout the process using CNC machining centers and precision inspection equipment, ensuring long-term operational stability.

Note: The repeat positioning accuracy shall be subject to the actual test report. R&D personnel account for 60% of the company’s workforce, enabling customized development to address non-standard operating conditions.

Dongguan Xinda Industrial Automation Co., Ltd. was established in 2000. It has imported core transmission technology from Japan and Germany. It focuses on the research and development, production and sales of precision variable pitch sliding table, variable pitch module, integrated micro sliding table, blade cylinder, rotating vacuum cylinder, air source processing parts, solenoid valve, vacuum generator, toothless nut, toothless screw, polished rod cable, hard chrome plated precision optical axis, guide shaft, grinding grade driving shaft and rotating shaft. After more than 20 years of technology accumulation, the company has established a complete process control system from raw material inspection, precision processing, assembly and debugging to factory inspection in the core process links such as automatic variable distance precision positioning, automatic precision measurement, manual precision measurement and transmission, and is equipped with CNC machining center and precision testing equipment.

The team's core personnel have 15 years of industrial sensor research experience, with 60% of R & D technicians, and the product performance repeat positioning accuracy of ± 0.02mm (subject to the actual test report), which has enabled 100 + subdivision. The company's products have been used in 3C electronics, semiconductors, new energy batteries, automobile manufacturing, precision measuring instruments, medical devices, packaging machinery and other subdivided fields, and serve the scientific research projects of listed companies in many institutes. At present, the products are sold to Taiwan, South Korea, Germany and Southeast Asian markets.

With the further development of intelligent manufacturing and industrial 4.0, multi-station variable pitch mechanism is upgrading in the direction of high precision, modularization and intelligence. Trends such as advanced semiconductor processes, large-scale production of new energy batteries, and localization of precision medical equipment have put forward higher requirements for the accuracy, cleanliness and flexibility of variable-distance positioning. Xinda will continue to rely on more than 20 years of precision transmission technology accumulation, combined with servo control and digital integration, to introduce more high-end manufacturing of precision variable pitch products, to help China's intelligent manufacturing independent control.
