Core Tip: In the case of Industry 4.0 and the shortage of manpower, in this trend of automation, the work in the field of grinding and polishing consumes a lot of manpower and urgently needs automated processing. To complete the automation, we need to solve the three problems of 1. hardware device, software program, and consumables.
In the case of Industry 4.0 and the shortage of manpower, in this trend of automation, the work in the field of grinding and polishing, due to the need to use a lot of manpower, is therefore one of the main goals of automation.
However, grinding and polishing operations, compared to other industries, are an area that relies heavily on operator experience. A feature like this also greatly increases the complexity of automation and the difficulty of execution.
If you want to solve such a problem, you need to start from three aspects: 1. Hardware equipment, 2. Software program, 3. Consumables
Problems with automated polishing
Hardware equipment:
In general, an automated special machine or robotic arm will be selected. The advantage of the robotic arm is its high flexibility and can be used with a wide range of workpieces; however, certain mechanical tolerances are not easily overcome. The special machine can process the style is more limited, but the mechanical precision is higher, relatively more suitable for the mode of mass production.
Software program:
It is also distinguished by a robotic arm and a special machine. If the robot arm is ideally suited to the processing of a variety of workpieces, the programming of the program requires engineers with both machining experience and programming skills. This part is the most difficult, and usually requires a long programming time, many It is not possible to respond to the production cycle of the product immediately. If it is a dedicated machine, since it is mostly a small amount of processing, it is not necessary to change the program from time to time, so the general problem is small.
Again, it is easier to ignore the "use of consumables":
In fact, consumables play a very important role! Many people ignore the choice of consumables when evaluating automated polishing. But in fact, people and machinery are different, and the consumables that people are suitable for are not necessarily the same as those that are suitable for machinery. Some consumables may not be usable, but they do have a great effect on the machine. Therefore, we should also pay attention to whether the consumables used are suitable for the current hardware equipment.
Automatic polishing consumables
In addition, the problem that the product size tolerance is too large needs to be corrected, and it is also one of the problems that mechanical polishing is difficult to overcome. Suitable consumables should also be able to make up for this problem.
We tried to explore the mechanical arm and manual polishing and found the following differences:
Robot arm and special machine
Although the rigidity of the manipulator is better than that of the man, the compensatory performance is poor. After all, the automatic detection capability of the robot currently has a lot of room to improve in terms of current technical capabilities. The compensatory and automatic detection capability is important because the polishing direction needs to be adjusted according to the state of the workpiece at any time. It is also necessary to adjust different strengths and angles according to different states of the grinding consumables to obtain consistent polishing results. .
Therefore, the ideal automatic grinding consumables must ensure the consistency of the grinding quality in addition to the function of a part of the automatic compensation. The robot arm cannot judge the state of the consumables, and the function of the compensation can basically be obtained by the elastic abrasive material.
However, the issue of consistency includes the uniformity of abrasives, the self-sharpening effect of abrasives, and the most important problems of “wear resistance” and “how to balance the grinding force”.
★ If it can be solved, you can even further use the rigidity of the robot arm to achieve the effect that cannot be achieved manually. In this way, it is not just imitating human actions, but the real mechanized era, which should be the face that automatic polishing should present.
Conclusion
Although Industry 4.0 is still a new project, there are still many technologies that need to be planned and introduced, and have not yet matured. However, if we can improve the technical engineering in this area early, there will be a lot of advantages! Regardless of the hardware equipment, software programs and related consumables, there must be detailed planning, and the choice of consumables can be more effective, and the perfect industry 4.0 will be closer.
