1) Comfort degree: This is an important goal that reflects the flexibility of the robot. Generally speaking, it is possible to reach 3 degrees of freedom in the robot working space, but welding must not only reach a certain position in the space, but also ensure the spatial attitude of the welding (cutting objects or welding tongs). Therefore, the arc welding and cutting robot needs at least 5 degrees of freedom, and the spot welding robot needs at least 6 degrees of freedom.
2) Load refers to the rated load that the robot can bear at the end. Welding and its cables, cutting things and gas pipes, welding tongs and cables, and cooling water pipes are all loads. As a result, the load of the arc welding and cutting robot can only be 6-10 kg. If the spot welding robot uses an integrated transformer and an integrated welding tong, its load capacity should be 6090kg. If a separate welding tong is used, the load capacity should be 4050kg.
3) The working space given by the working space maker is a large space that can be reached by the robot without any terminal manipulator, which is indicated by a graphic. After installing the torch (or tongs), special attention should be paid to the attitude of the torch. The actual weldable space will be one level smaller than the space provided by the manufacturer. It is necessary to use the scale drawing method or the model method to carefully calculate to confirm whether it meets the actual needs.
4) High speed: This is an important goal that affects the production efficiency in production. The product manual gives the maximum linear velocity that can be reached at the end of the robot's wrist with each axis synchronized. Due to the low speed required for welding, the high speed only affects the seating of the weld (or welding tongs), the idle stroke and the return end time. Normally, the cutting robot of the welding robot depends on the different cutting method.
5) Point-to-point repeatability: This is one of the important goals of robot performance. Regarding the spot welding robot, starting from the process requirements, its accuracy should be less than 1/2 of the diameter of the welding electrode, i.e. +12mm. Regarding arc welding robots, their diameter should be less than 1/2 of the diameter of the welding wire, i.e. 0.2 to 0.4 mm.
6) Trajectory repeatabilityThis goal is very important for arc welding robots and cutting robots, but each robot manufacturer does not give this goal, because the measurement is more complicated. However, each robot maker does this in-house and should insist on accurate data. For arc welding and cutting robots, the trajectory repeatability should be less than 1/2 of the diameter of the wire or the diameter of the cut hole in the east and west, and usually need to reach +0.30.5mm or less.
7) User memory capacity refers to the capacity of the main computer memory in the robot controller. This reflects the length of the educational program that the robot is able to store and is related to the complexity of the artifacts that can be processed. That is, large education points. It is usually indicated by the number of coefficients that can store robot instructions and the total number of bytes (Bytes) stored, and it is also indicated by the number of large teach-in points.
8) Interpolation functionRegarding arc welding, cutting and spot welding robots, it should have linear interpolation and circular interpolation functions.
9) Speech conversion functionEach factory robot has its own special language, but its screen display can be displayed in a variety of languages. For example, Decca robots are able to pick and choose to appear in English, German, French, Italy, Spain, Switzerland and other languages. This is very useful for the work of bento workers. Chinese home robots can appear in Chinese.
