Four applications of load cells in robots

With the development of industrial technology, the application of robots has become more and more extensive, and its efficient work efficiency has greatly improved the production capacity of enterprises. As everyone knows, industrial robots can't test their surrounding environment very well. They need to be integrated with the professional equipment to maintain some functions. A lot of different controllers are introduced into the intelligent robot, which makes the intelligent robot more sensitive and intelligent. In this short introduction, four applications of load cells in robots:

1.Target positioning
We often come into contact with customers who generally believe that the primary method of locating and quantifying parts is to use a vision sensor. But in fact, this is not the only solution. There is no doubt that visual recognition systems are a good way to accurately position or quantify parts, but the use of force sensors to find and verify spare parts works. In fact, to do this, you need a 3D vision system. The robot only needs to determine the height of a pile of objects and then constantly adjust its grip height.

2. Constant force
Force sensors are first manufactured for polishing, polishing and other applications. Because this kind of application has no way to maintain automation technology, because the intelligent robot must have some force feedback to clarify that the force value it promotes is not worthwhile. By introducing a force feedback circuit into the program, these applications can be easily automated to achieve consistency in the manufacturing process. . In this case, you need to use an external device instead of an embedded solution from a robot manufacturer.

3. Weighing things
When the robot grabs something, the load cells can distinguish them based on their weight. This can also be used to distinguish between different parts with similar shapes. However, in real life, it is useful to know if there is something right in your thread, or if something is falling. That can really help you in your production process. Force sensors can easily do this.

4. Repeating force
When you have considered applying intelligent robots to do assembly line daily tasks, you expect intelligent robots to look over and see the same daily tasks. However, one of the reasons why it is difficult to automate assembly tasks is that they require an operator to perform force detection. By introducing a pressure sensor, the external force applied during assembly can be felt. When the robot is installing a battery on a mobile phone, it requires a very accurate force. These parts are easily broken, so it is really difficult to assemble them without damage. This is why a very low force threshold should be set to prevent component misalignment and damage.

Micro sensors have the following advantages:
1. Self-compensation effect: Discrete system deviation, temperature transition in data signal test, and compensation caused by zero drift and sensitivity drift of data signal, no response delay time, noise and cross-check;
2, self-diagnosis function: system self-diagnosis when the power is turned on, self-diagnosis when the system is operating, self-diagnosis when the system is faulty, fault location and component determination;
3. Self-correction function: setting and checking of parameters in the system, automatic range conversion in the test, automatic calculation of measurement parameters, etc.;
4. Automatic data storage, analysis, processing and transmission;
5. The central processing unit and the microcomputer and the basic controller have two-way communication functions. New products that continue to emerge, with the advancement of micro-sensor technology, can reduce costs through engineering without an analyzer.
