Specifications

Suction Pump: Used for suctioning objects

Introduction

• The suction pump, also known as a vacuum suction pump, features an inlet and outlet nozzle, an outlet nozzle, and a simple structure, compact size, ease of use, low noise, and excellent self-priming capability. The suction pump kit acts as the end effector of the robotic arm to perform the suctioning function.

• Suction Pump Accessories: Power Cord x1, DuPont Cables x10, One-Input Two-Output Connecting Cable x1, Several Lego Technic Pieces

Working Principle

• When suctioning an object: The pump activates to suck air from the object and then stops, preventing air leakage.
• When releasing an object: The electronic valve activates, the air release valve opens, and air enters the vacuum cup and releases the object.

Applicable Objects

• Paper/Plastic Sheets
• Flat, Smooth Objects
• Cards, etc.

Installation and Use

• Check that the accessories package contains all the necessary items: LEGO connectors, DuPont cables, and a dual-head suction pump.

• Dual-head suction pump installation:

Structural installation:

Insert the LEGO connectors into the designated sockets on the suction pump.

Align the suction pump with the connector plugged in with the socket at the end of the robotic arm and insert it:

• Electrical connections:

  Select a male-female Dupont cable and insert the female end into the marked pin socket on the suction pump box:

  Male-female DuPont wire: Note the correspondence between the DuPont wire colors and pins in the figure:

  1. Insert the male connector into the pins on the base of the robotic arm according to the given correspondence:

     The left side is the suction pump pin, and the right side is the robotic arm pin GND -> GND
     5V -> 5V
     G2 -> 21
     G5 -> 20

• Programming Development:

Using Python to program a suction pump

The code is as follows:

• 280-M5 version:

    from pymycobot.mycobot280 import MyCobot280
    import time
  
    # Initialize a MyCobot280 object
    mc = MyCobot280("COM3", 115200)
  
    # Turn on the suction pump
    def pump_on():
        # Open the solenoid valve
        mc.set_basic_output(5, 0)
        time.sleep(0.05)
  
    # Stop priming the pump
    def pump_off():
        # Close the solenoid valve
        mc.set_basic_output(5, 1)
        time.sleep(0.05)
        # The deflation valve starts working
        mc.set_basic_output(2, 0)
        time.sleep(1)
        mc.set_basic_output(2, 1)
        time.sleep(0.05)
  
    pump_off()
    time.sleep(3)
    pump_on()
    time.sleep(3)
    pump_off()
    time.sleep(3)
  
    GPIO.cleanup() # release pin channel
  

  • 280-Pi 版本：

    from pymycobot.mycobot280 import MyCobot280
    from pymycobot import PI_PORT, PI_BAUD  # When using the Raspberry Pi version of mycobot, you can reference these two variables to initialize MyCobot
    import time
    import RPi.GPIO as GPIO
    
    # Initialize a MyCobot280 object
    mc = MyCobot280(PI_PORT, PI_BAUD)
    
    # Initialization
    GPIO.setmode(GPIO.BCM)
    # Pins 20/21 control the solenoid valve and the bleed valve, respectively
    GPIO.setup(20, GPIO.OUT)
    GPIO.setup(21, GPIO.OUT)
    
    # Turn on the suction pump
    def pump_on():
      # Open the solenoid valve
      GPIO.output(20，0)
    
    # Stop priming the pump
    def pump_off():
      # Close the solenoid valve
      GPIO.output(20，1)
      time.sleep(0.05)
      # Open the vent valve
      GPIO.output(21，0)
      time.sleep(1)
      GPIO.output(21，1)
      time.sleep(0.05)
    
    pump_off()
    time.sleep(3)
    pump_on()
    time.sleep(3)
    pump_off()
    time.sleep(3)
    
    GPIO.cleanup() # release pin channel
