Specifications

Suction pump: Used for adsorbing objects

Introduction

• Suction pump, that is, vacuum adsorption pump, has one suction nozzle and one exhaust nozzle. It has the advantages of simple structure, small size, easy to use, low noise, and good self-priming ability. By controlling the suction pump kit as the end effector of the robot arm, the function of adsorbing objects is performed.

• Suction pump accessories: power cord x1, DuPont line x10, one-input and two-output connection line x1, Lego technology parts x several

Working principle

• When sucking objects: the air pump starts to suck air and adsorb objects and then stops, and there will be no leakage in a short time.
• When putting down the object: the electronic valve starts, the air release valve opens, and air enters the vacuum suction cup to separate the sucked object.

Applicable objects

• Paper/plastic sheets
• Flat and smooth objects
• Cards, etc.

Installation and use

• Check whether the accessories package is complete: Lego connector, Dupont wire, pump

Pump installation:

Structural installation

Insert the Lego connector into the reserved socket on the pump:

Align the pump with the connector plugged in to the jack at the end of the robot arm and insert it:

Electrical connection

Select the male-female DuPont wire and insert the female end into the socket marked with pins on the suction pump box:

Male-female DuPont wire:

Note the correspondence between the DuPont wire color and the pin in the figure:

Insert the male end into the pin of the robot arm base according to the given correspondence:

280 PI wiring method

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

280 M5 wiring method

The left side is the suction pump pin, and the right side is the robot arm pin GND -> GND 5V -> 5V G2 -> 2 G5 -> 5

python programming control
