Industry topics
In automated production scenarios in manufacturing industries such as electronics, hardware, and plastics, parallel robotic arms (spider arms) are often used for high-speed positioning and precision palletizing of lightly loaded materials. However, this process faces multiple challenges in practical applications:
The control algorithm for high-cost parallel robotic arms is very complex. In the industry, dedicated imported robot controllers are generally used to implement it, and the controllers are very expensive.
The trade-off between precision and efficiency makes it difficult to maintain positioning accuracy in high-speed material handling. Precision parts are prone to wear due to impact, resulting in a high risk of jamming and affecting the stability of the production line.
Traditional robotic arms are inefficient when switching between different types of materials. When dealing with materials of various shapes and postures, such as mobile phone parts, spring clips, and powder metallurgy irregular parts, they require frequent manual debugging of the robot program, which is time-consuming, labor-intensive, and prone to errors.
Leadshine Process Solutions
Intelligent flexible tray loading system and process function blocks
To address the aforementioned pain points, Leadshine's flexible trolley solution based on the Delta parallel robotic arm achieves multi-dimensional technological breakthroughs through deep collaboration between the vision system and core functional blocks:
01. Visually Guided Flexible Feeding Technology
The high-precision vision system identifies the shape, position, and posture of materials in real time. The self-developed vision management system can quickly recall pre-stored programs based on material characteristics, enabling program switching between multiple material types without manual intervention. The Delta robotic arm precisely controls the gripping angle and force based on visual feedback, seamlessly cooperating with the Feeder, Vision, and Robot modules of the flexible feeding station, fundamentally solving the problem of low efficiency in switching between multiple material types.
02. Core functional blocks enable efficient control and programming

■ Simplified parameter configuration: Built-in Delta model parameter structure (stTripodPara), requiring only input of physical parameters such as arm length and platform radius, automatically completes the construction of the robotic arm kinematic model, completely eliminating the need for complex algorithm debugging; ■ Full-function operation coverage: Supports 12+ core operations including axis group parameter configuration, enable/disable enable, absolute positioning, alarm reset, origin calibration, and inching, meeting the full-process control needs from initialization to anomaly handling; ■ Real-time status visualization: Real-time output of X/Y/Z 3D position in the MCS coordinate system (accuracy ±0.1mm), and real-time monitoring of equipment operation through xGroupServoOn (enable status), eAxisGroupState (state machine), and eErrorNum (fault code), improving anomaly troubleshooting efficiency by more than 50%.
LMC_LsBlendMotionFor4Pos function block — High-speed precision motion planning
■ One-click generation of continuous trajectory: Supports 2-4 point gantry motion in space (such as A→B point transport). Simply input the coordinates of 4 points (afBlendPos array) and trigger the execution signal (axBlendExecute) to automatically generate the optimal smooth path; ■ Flexible and adjustable parameters: Supports fine configuration of interpolation speed (fBlendVelocity) and acceleration/deceleration time (fAccTime/fDecTime) to adapt to the transport speed requirements of different materials; ■ Precision transport protection: Built-in buffer mode (eBufferMode) and transition radius parameter (afTransitionParameter) avoid inertial impact during acceleration/deceleration stages through trajectory optimization, ensuring damage-free transport of precision parts.
