[0003] With the development of automation technology, industrial robots and automatic assembly lines are increasingly widely used. In these application scenarios, the clamping jaw is a key component for performing operations such as grabbing and placing. In order to adapt to different workpiece sizes and shapes, modular design has become an important trend in the development of clamping jaws. However, the clamping jaws in the prior art have some problems during use, especially in terms of clamping stability and preventing workpiece from falling off.

[0004] Traditional clamping jaw designs often use a single clamping surface, which limits their ability to effectively clamp different shaped workpieces. When encountering non-standard shaped or irregular surface workpieces, the clamping force distribution is uneven due to the small contact area, increasing the risk of workpiece slipping.

[0005] To address the above problems, although there are some solutions, such as trying to improve clamping performance by adding additional fixtures or improving material friction coefficient, these methods increase additional costs and do not fundamentally solve the challenges caused by the limitations of the clamping surface. Especially in the demand for quickly changing production lines with different specifications of workpieces, how to achieve reliable grabbing for multiple workpieces has become a technical problem to be solved.
