Grinding robot quality appraisal

polishing robot is an industrial robot engaged in polishing. It replaces manual polishing with intelligence, improves work efficiency and ensures high-quality products.

Robot grinding is currently mainly divided into two working methods:

One is to clamp the grinding tool through the robot's end effector, actively contact the workpiece, and the workpiece is relatively fixed. This method is usually used when the robot's load capacity is poor and the quality of the OEM workpiece is poor. When both the workpiece and the volume are large, it is called a tool-type grinding robot;

The other is a robot end effector that clamps the workpiece and grinds it with the grinding tool in close contact with the workpiece. The grinding tool is relatively fixed. This method is usually used when the workpiece is small in size and requires high grinding accuracy. It is called a workpiece-type grinding robot. At present, it is widely used in 3C industry, hardware furniture, medical equipment, auto parts, small household appliances and many other industries.

Zhongke Testing and Appraisal Institute can provide quality appraisal services for polishing robots and make accurate appraisals in terms of product design analysis, load analysis and product quality analysis.

grinding is divided into two forms strictly according to different working methods: tool-type grinding robot and workpiece-type grinding robot.

tool-type grinding robot is mainly used for grinding and processing of larger workpieces, such as small and medium-sized castings, blades, extra-large tools and molds, etc.

workpiece-type grinding robot is mainly suitable for automatic grinding and processing of self-growing parts. It also needs to be equipped with Kewei robots for loading and unloading according to needs to complete the automatic transportation of polished workpieces.

A factory purchased two grinding robot equipment from a machinery company for production. The machinery company guaranteed that the quality of the grinding robot equipment it sold complied with the technical standards agreed in the contract. However, after actual use, it was found that the chamfering and grinding (polishing) of the grinding robot were not up to standard. The factory believed that the polishing robot involved in the case had quality defects and sued the local court.

Our company was entrusted by the court to evaluate whether the robot chamfering, chamfering effect and side polishing of the polishing robot equipment involved in the case were qualified.

identification and analysis results:

The quality analysis expert team conducted relevant information, on-site investigation and inspection, and inspection and testing data on the "polishing robot" involved in the case. After discussion and comprehensive technical analysis, the following quality analysis opinions were made:

The "grinding robot equipment" involved in the case has obvious unevenness and color difference in the chamfered edges and side grinding (polishing), which does not meet the requirements agreed by the supplier and the buyer.
