The working principle can be summarized in four core steps: Image Acquisition Process: The system captures an image of the object using an industrial camera and specialized lighting. Key Elements: Lighting: Provides stable, uniform illumination to highlight features of interest and suppress noise. Camera: Converts light into a digital image signal. Image Processing Process: The raw image is sent to an image processor for preprocessing. Key Operations: Noise reduction, contrast enhancement, edge sharpening to prepare the image for analysis. Feature Extraction and Analysis Process: The system’s “brain” analyzes the processed image against preset standards or templates. Key Operations: Measurement: Calculates pixel distances and converts them to real-world dimensions. Pattern Matching: Compares the image to a known good template. Recognition: […]
Classified by Actuation Method Single-Acting Cylinders Principle: Air pressure drives in one direction (extend), and a spring (or external force) returns it. Characteristics: Simple, low air consumption. Uneven force, limited stroke. Double-Acting Cylinders Principle: Air pressure drives both extension and retraction. Characteristics: High, controllable force. Standard, most common type. Classified by Function & Special Structure Rodless Cylinders Principle: The piston drives an external carriage via magnetic or mechanical coupling. No piston rod extends. Characteristics: Saves space, allows long strokes. Guided Cylinders Principle: Integrated linear guide resists side loads and torque. Characteristics: High rigidity, precision, prevents binding. Compact Cylinders Principle: Very low profile/short axial length. Characteristics: Saves height, used in tight spaces. Rotary Cylinders Principle: Converts […]
Adjusting a pusher feeder focuses on optimizing mechanical stroke, timing, and sensor feedback. Mechanical Adjustment Inspection & Cleaning Safety: Disconnect air and power. Action: Clean and check for wear on the pusher, guides, and hopper. Adjust Pusher Stroke Goal: Ensure the pusher fully ejects the part without over-travel. Method: For Pneumatic Cylinders: Adjust sensor positions or flow control valves. For Electric Actuators: Set travel limits in the control software. Adjust Clearance Goal: Optimize gap between pusher and hopper (slightly larger than part thickness). Pneumatic/Electrical Adjustment Adjust Speed Goal: Balance speed and stability. Method: Use flow control valves on the cylinder. Extend fast for positive ejection; retract slower to reduce impact. Adjust Sensor Positions Goal: Accurately detect “part present” and “low hopper” states. […]
Compression Riveter (for Solid Rivets) Process: Insert a solid rivet into a pre-drilled hole. The factory head is supported by a bucking bar or die below. A riveting head applies high pressure to upset the protruding shank. The shank plastically deforms, filling the hole and forming a second shop head. Core: Uses static pressure to create a permanent mechanical lock. Blind Rivet Gun (for Pop Rivets) Process: Insert a blind rivet into the hole. The tool’s jaws grip the rivet’s mandrel. The gun head pulls the mandrel back while reacting against the rivet body. This pulls the mandrel head, […]
Classified by Measured Property Position/Displacement Sensors: Detect presence, position, or distance. Force/Pressure Sensors: Measure force, weight, or torque. Vision Sensors: Capture images for identification, inspection, etc. Temperature Sensors: Measure temperature. Flow Sensors: Measure gas/liquid flow rate. Level Sensors: Detect liquid level in a tank. Classified by Working Principle Photoelectric Sensors: Use light (blocked or reflected by an object). Through-beam: Separate emitter and receiver. Retro-reflective: Emitter and receiver together, detect light from a reflector. Diffuse reflective: Detect light reflected directly from the object. Proximity Sensors: Detect nearby objects without contact. Inductive: Detect metals only. Capacitive: Detect both metals and non-metals. Fiber Optic Sensors: Use optical fibers to guide light to a […]
Limited Workspace Description: Its working envelope is relatively small and dome-shaped due to the parallel-arm structure. Pain Point: Unsuitable for long-distance movement; ideal only for compact work areas. Very Low Payload Capacity Description: Designed for speed, with lightweight components limiting load capacity. Pain Point: Typically handles only a few grams to a few hundred grams. Restricted End-Effector Orientation Description: The moving platform has limited ability to independently control tool orientation during motion. Pain Point: Not ideal for tasks requiring complex tool reorientation, like intricate screwdriving. Fixed Mounting Configuration Description: Typically ceiling-mounted, with a fixed work zone after installation. Pain Point: Reduces layout flexibility compared to floor-mounted robots on tracks. More Complex […]
The speed of a centrifugal feeder is one of its standout features. It typically achieves higher and smoother feeding rates compared to vibratory bowls for suitable parts. Speed Range and Advantages High-Speed Range: For small, uniform parts, centrifugal feeders can easily achieve speeds ranging from hundreds to thousands of parts per minute. Speeds between 1000 to 4000 PPM are common. Comparative Advantage: Their speed often surpasses that of vibratory bowls due to continuous rotary motion, which is more efficient than reciprocating vibration. Key Factors Influencing Speed Part Characteristics Size & Weight: Small, lightweight parts are accelerated and fed most efficiently. Shape & Flowability: Uniform, smooth, non-tangling parts achieve the highest speeds. Stability: Parts must remain stable […]
Extremely High Speed Description: The lightweight moving platform is driven by multiple servo motors simultaneously, allowing for very high acceleration and deceleration. Advantage: Ideal for high-speed picking, packaging, and sorting, significantly outperforming traditional serial robots in cycle time. Outstanding Repeatability Description: The load is shared by multiple arms, creating a stable, rigid structure that minimizes cumulative error and vibration. Advantage: Maintains high positional accuracy even at top speeds, perfect for precision pick-and-place. Excellent Dynamic Performance Description: High rigidity and low moving mass enable smooth, high-speed motion with minimal settling time. Advantage: Enables fast “point-to-point” jumps, reducing idle time and increasing overall efficiency. Compact Footprint Description: The motors are typically mounted on the […]
The core principle is that multiple independent arms work in parallel to drive a single moving platform. Core Structure Base Platform: The fixed base. Moving Platform: The end-effector that carries the tooling. Drive Arms: Typically 3 or 4 arms, each driven by an independent servo motor on the base. Forearm Links: Lightweight rods connecting the drive arms to the moving platform via spherical joints. Working Process Command Reception: The control system receives the target coordinates. Inverse Kinematics Calculation: The system calculates the required angle for each servo motor to reach the target simultaneously. Coordinated Drive: All servo motors rotate their drive arms precisely and in sync. Platform Movement: The motion of the […]
