[0027] The utility model proposes a multi-carrier variable distance correction system, the basic principle of which is to drive carriers with different initial positions to move to the final position through the coordinated work of 8 groups of rodless cylinders 5, while changing the spacing between the carriers. In this process, the sliding adjustment of the product angle on the carrier is achieved in combination with a specially designed cam and groove structure. 8 groups of rodless cylinders 5 are designed, and each group of cylinders can be independently controlled to achieve precise movement and spacing adjustment of the carrier. A special cam and groove structure is installed on the carrier, so that the cam can drive the product to change its angle when sliding in the groove.
