The teaching device, also known as the teaching programmer or teaching pendant, is a handheld device for manual manipulation, programming, parameter configuration and monitoring of robots; It is the core component of robot control system, and is a device used to register and store mechanical movement or process memory. The device is executed by electronic system or computer system.
Industrial robot teaching means that the programmer uses various teaching methods to "inform" the robot of the action information and operation information in advance, which mainly includes three categories:
1. Robot position and posture information, trajectory and path point information;
2. Information such as robot task action sequence;
3. Information such as robot action, additional conditions during operation, speed and acceleration of robot action, and work content information.
Question 1: Can teaching aids from different manufacturers be used universally?
Answer: No!
The industrial robot is controlled by the controller and connected with the teaching device with keys and touch screen through a 5-8m long cable. This requires that the system, algorithm and software between the teaching device and the robot must be compatible with each other, so as to form a closed-loop adaptation.
In fact, each enterprise has its own logic programming. Different brands of products have different systems and software. For example, C++, Windows, ST languages are common system programming languages. Industrial robots of different brands do not communicate with each other.
As a result, different brands of industrial robots cannot use the universal teaching device.
Question 2. Can the teaching device be universal for the same product series?
Answer: Not necessarily.
Every enterprise has the experience of product iteration, system iteration, and software iteration. If the system and software are upgraded, their communication between products of different versions may be incompatible with each other. For example, the two new and old system products of Windows 2010 and Windows 2000 will be incompatible with each other, so the products of different systems cannot share the teaching device.
In addition, products produced by the same enterprise may also use multiple operating systems and software, which are generally incompatible.
There is an exception that can be universal, but it needs to be specially developed by the original factory. However, for users, this will be a big expense, which will not pay off.
Q3: Can we not use the teaching pendant?
Answer: Yes.
The teaching methods of industrial robots include direct teaching method, remote control teaching method, indirect teaching method, etc. The teaching box is only a common method of use, but can also be realized by other ways, such as directly inputting parameters through a computer.
At present, many special equipment for integrated Scara robots do not need teaching devices. For example, special equipment for CCD detection, integrated Scara robots are equipped with visual aids, and teaching can be realized through computers.
Question 4: Can I directly control the robot with off-line programming software?
Answer: Yes.
Such schemes are most common in welding lines. In the scene with many robots such as automobile manufacturing, the efficiency of debugging one by one by using the teaching device will be very low. At this time, the robot is usually imported one by one by using the pre written program, so as to quickly achieve parameter setting.
Of course, in order to prevent accidents, the teaching device will also be carried with you.
Question 5: Can multiple robots share one teaching pendant?
Answer: Yes.
As long as the robot is a mutually compatible device, it can be shared by multiple devices with one teaching pendant.
However, from the perspective of management, if there is a fault in the production line, only one teaching pendant will cause great trouble for troubleshooting, because when there is only one teaching pendant, the parameters of each robot must be queried through the computer, which is very unfavorable to work. If each robot has an independent teaching pendant, when troubleshooting, it is only necessary to check the parameters in the corresponding teaching pendant, which is very convenient and fast.
Otherwise, it will affect the production efficiency of the enterprise, and the gain will not be worth the loss.
