In the automated feeding of small parts such as fasteners, stamped parts, and injection molded parts, spider hand flexible feeding stations have almost become standard.
But when I really started running, I realized that I wanted to run fast but was afraid of shaking and collisions; I want to have a wide range of materials, but I'm afraid of edge interference
The smartPX multi in one drive control integrated machine+PH3 motor has delivered a beautiful performance in a Delta spider hand flexible feeding station that is currently in operation.
What is a station master like?
This workstation consists of a spider phone robot, a visual system, a vibrating disc, and a suction nozzle, specifically designed to grip fasteners such as screws, nuts, lathe parts, stamped parts, cold heading parts, etc. that can be placed smoothly.
The requirements for the equipment are very clear:
The beat should reach 60 to 100 beats per minute, with a load of 0.5kg and positioning accuracy controlled within ± 0.5mm.
At the same time, the feeding range should be as large as possible - the suction nozzle should be able to detect the edge of the vibrating plate, but it must not collide with the edge during high-speed movement. In addition, it should also support belt tracking for material picking and unloading, and be able to communicate with the visual system and vibration disc through TCP/IP and Modbus TCP.
How to adopt a comprehensive solution for high-tech sports control?
1. Strong computing power, fast and detailed path planning
The high flexibility trajectory planning algorithm built into the smartPX controller, combined with the micro interpolation function of high-performance drivers, achieves the ultimate smoothness and high-speed response of motion trajectories. In high-speed grasping tasks, this directly determines whether it can meet customers' demanding rhythm requirements.
2. Double smoothness, stable as a rock during high-speed operation
The customer was initially concerned that after the speed was increased, the machine and suction nozzle would shake, affecting the feeding accuracy and equipment lifespan.
The approach of Gaochuang is:
Trajectory foresight: Set transition segments for multiple trajectory segments during movement to make robot routing smoother
Instruction smoothing: Utilizing the built-in instruction smoothing function of the drive control integrated system, smooth processing of motor current instructions is achieved while ensuring multi axis trajectory synchronization and predictability
In actual operation, even with high-speed reciprocating, the robot and the end of the nozzle are very light and smooth.
3. Automatic path planning, with a wide range of material retrieval without collision
In order to balance "maximum working range" and "collision free high-speed operation", the controller will automatically plan the motion curve according to different working positions.
For example, when picking materials from the edge of a vibrating disc, the system will automatically limit the overshoot trajectory, allowing the suction nozzle to approach the edge without colliding with the disc due to inertia - this is particularly critical in narrow spaces.
4. One step communication and calibration
The visual system and vibration disc are connected to smartPX through TCP/IP and Modbus TCP, and are calibrated with the camera and robot coordinate system to achieve precise grasping. Simultaneously supporting belt tracking, it can dynamically follow the belt to retrieve or release materials, leaving interfaces for subsequent production.
What is the actual effect of running it out?
In actual production, 63 products were placed in 51 seconds, which is equivalent to steadily grabbing 75 products per minute, fully meeting the requirements of the 60-100 pcs/min.
In order to test the limits, the device also conducted an empty run test: canceling the inhalation wait, using visual simulation to swing the disc, running one round in at least 36 seconds, which can be converted to 105 times per minute.
This data indicates that the response and path smoothing capabilities of the control system are fully capable of supporting the potential for higher beats.
What are the highlights of this plan?
If summarized in one sentence: high cost performance+complete functions+smooth operation+safe and collision free.
Specifically:
For spider hand flexible feeding scenarios that require 60-100 beats per minute, ± 0.5mm accuracy, large-scale material collection, and non collision, smartPX+PH3 provides a complete solution with high cost-effectiveness, strong usability, and smooth operation. In the future, Gaochuang will continue to deeply cultivate the field of motion control, continuously iterate technology and solutions, help more manufacturing enterprises achieve automation and intelligent upgrades, and empower the industry to improve quality and efficiency!
