In industrial production, dispensing is required in many places, such as integrated circuits, printed circuit boards, color LCD panels, electronic components (such as relays, speakers), automotive parts, and so on. Traditional dispensing is done manually by workers. With the rapid development of automation technology, manual dispensing is far from meeting the industrial requirements. Manual dispensing has the disadvantages of slow speed and poor precision. The market demands a device that is fast, efficient, and highly accurate. Therefore, a fully automatic dispensing robot appeared.
Today, when technology is the primary productive force, the emergence of fully automatic dispensing robots has brought unprecedented opportunities and development to the dispensing industry. The efficiency of dispensing is greatly improved, the production cost is reduced, and the advantages of high precision, high reliability, and strong adaptability are obtained.
The teach-in programmer system allows the user to communicate easily and conveniently with the dispensing robot, allowing the robot to move according to the user's ideas and dispensing process requirements. It can easily control the dispensing robot, send a variety of motion commands, and perform dispensing of various graphics. In addition, after a simple modification, the system can also be used in robots such as spot welding and laser cutting.
1 system structure
1.1 Dispensing robot construction
The dispensing robot consists of a "mechanical + motor + motion control card". Its system structure is shown below:
Figure shows the structure of a plastic robot
The mechanical part is a three-degree-of-freedom transmission mechanism platform. The rubber head can be positioned by mechanical movement to any (x, y, z) coordinate of the space. The motion control card is actually equivalent to a smart computer. It sends a pulse to the drive of the motor, causing the motor to move mechanically. It can control the machine to go out of various trajectories, flexibly control the speed of motion, acceleration, and position with high precision. Its positioning accuracy can reach 0.01mm. In addition, this card also has an RS232 interface to communicate with external devices such as a teach pendant or PC.
1.2 Teaching the structure of the programmer
The main hardware structure of the teaching box is shown below:
Figure 2 shows the structure of the teaching box hardware
The teaching box is mainly composed of CPU, LCD display, keyboard, flash power-down memory and communication module.
The operator uses the keyboard and LCD for human-computer interaction. The CPU turns the operator's idea into a machine command and sends it to the motion control card through the RS232 communication port. In addition, the CPU can also store some graphics set by the operator in a flashable power-down memory in a file manner.
