05/25/2026Delta’s Micro-Scale Linear Motion Solution: LPL Linear Actuator Enhances Z-Axis Precision Assembly Performance

In precision electronics assembly, optics, and semiconductor applications, Z-axis tasks such as pick-and-place, pressing, and assembly often require high speed, high accuracy, and force control at the same time. As components become smaller and thinner with increasing process density, equipment must respond faster while staying stable at the moment of contact to prevent damage and yield volatility. Take a rotary motor with a screw-driven stage as an example. The indirect-drive solution involves more integration steps and delivers slower responses with poor force control. Reciprocating motion for long periods, backlash, wear, and lubrication needs can also lead to noise, heat buildup, accuracy drift, and higher maintenance costs. When processes require higher throughput and tighter tolerances, balancing speed and quality without extra tuning becomes a key challenge. To address these pain points, Delta has presented the Micro-Scale Linear Motor Motion Control Solution that integrates a dedicated servo drive system, the Linear Pocket Actuator LPL, and EtherCAT controllers (PLC-based or PC-based). Built on a direct-drive structure with high-resolution position feedback, it supports high-speed, high-precision motion with stable force control. Combined with Delta’s machine vision products, it can be applied to processes such as die pick-and-place and IC inspection. At the core of the solution is the Linear Pocket Actuator LPL. Its zero-backlash and direct-drive design enhances positioning accuracy while reducing maintenance costs. With a slim, palm-sized form factor, it also increases layout flexibility and supports side-by-side installation to raise device density per equipment. To reduce contact-related risk for delicate parts, the LPL can pair with Delta drives to enable Soft Landing. It delivers precise downforce control without overshoot, using an optical linear encoder for high-resolution position feedback and a force sensor for real-time contact buffering and force regulation. This helps reduce risks such as surface damage, collision impact, or over-compression in pick-and-place and pressing tasks. In addition, the LPL can log and upload key parameters and motion data to support process traceability and anomaly analysis. Delta’s Micro-Scale Linear Motion Control Solution is designed to balance high precision, high speed and stable force control and has been deployed across multiple application fields. In electronics insertion, Soft Landing reduces issues such as pin deformation and PCB cracking. Combined with fast response and micron-level repeatable positioning, it delivers about a 10% gain in both insertion speed and yield. In optical product assembly, direct drive enables micron-level motion control, high responsiveness shortens alignment time, and force feedback protects workpieces, helping deliver a 20% speed increase and a 25% yield gain. In semiconductor packaging, where point-to-point strokes are extremely short, thermal expansion is highly influential, and planarity tolerances are tight, the solution optimizes Cycle Time by 15% and boosts yield by 20%. With multi-axis synchronous motion, precise force control, and stable position feedback, the solution enhances Z-axis assembly accuracy and yield, meeting the growing demand for miniaturized and high-precision manufacturing.

08/15/2024Delta Automatic Tire Cord Splicing System Solution Enhances Manufacturing Efficiency with Significant Benefits for Production

Tires are an essential component of vehicles, designed to provide traction, support vehicle weight, absorb vibrations, and reduce shocks during motion. The quality and performance of tires directly affect driving safety and comfort. Within a tire's inner layers, the cord is the core material that makes up the tire's skeleton, which is composed of tough fibers such as nylon, polyester, and rubber. Its primary functions are to stabilize the overall tire structure, strengthen the tread to resist punctures, and absorb road bumps. To enhance tire reliability and durability, high-quality tire cords must combine tough fiber materials, tight weaving, and firm adhesion to the rubber matrix of the tire. Therefore, quality control is important during tire cord production. The traditional tire cord cutting process mainly adopts semi-automated technology, where the first half involves automatic cutting by equipment, and the second half requires manual splicing by operators. However, manual splicing might raise issues such as inconsistent precision, low efficiency, high costs, difficulties in quality control, and poor working environment. As a result, the production capacity and quality of tire cords cannot be effectively controlled, making it challenging to meet the demands of modern tire manufacturing.

This is a major challenge for industry, which has growing requirements for assembly machines that ensure greater stability, smaller size, higher speed and exceptional accuracy. The key to reaching the ideal yield rate in electronics assembly lies in the Z-axis motion, which refers to an object’s movement along the vertical direction. On the assembly line, the Z-axis motion entails pick-and-place, load-and-unload, pressing, surface mounting, die bonding, insertion, and inspection of chips and components. Any unexpected error during the Z-axis motion can lead to component damage, which consequently affects the product yield rate. To cater to the small size and slim design of electronic products, the mechanism that controls and drives the Z-axis motion has to be as compact as the workpiece. To optimize the assembly line utilization, multi-axis synchronization is also crucial for maximizing productivity. In order to enhance the Z-axis motion efficiency, the assembly equipment has to overcome the various challenges in terms of force control, force sensing, position feedback, direct drive mechanism design, and size reduction, and to shorten cycle times to break the bottleneck of unsatisfactory yield rates. To address the demands of high-precision assembly, Delta has launched the Linear Pocket Actuator LPL Series, a linear motion product that integrates linear motors, optical linear encoders, force sensors, rotary servo motors, encoders, rails and frameworks within a compact module.
