[0002] As one of the most important and critical processes in product assembly, the automatic positioning mechanism is mainly used to automatically position and fix the assembly in a specific location, so that the subsequent gripping mechanism can accurately grasp it and ensure the product assembly yield.

[0003] Currently commonly used automatic positioning mechanisms, such as Figure 4 As shown, the assembly includes a positioning fixture 14, a V-shaped positioning block 15, and a cylinder 2. The positioning fixture 14 has a contour groove 301. The V-shaped positioning block 15 is fixed to the guide rod of the cylinder 2. In use, the assembly 13 is placed in the contour groove 301, and the guide rod of the cylinder 2 extends to drive the V-shaped positioning block 15 to press against the side corner of the assembly 13, thereby achieving precise positioning of the assembly 13.

[0004] The current problem in actual use is that during the positioning of the assembly 13, the unstable air pressure of the cylinder 2 can easily cause the V-shaped positioning block 15 to move too far forward or too far backward, resulting in damage to the assembly 13 or inaccurate positioning.
