| The present disclosure provides a material clamping system including a gantry, a plurality of clamping devices and a controller. The clamping devices are serially disposed at the gantry. The clamping device includes an elevating mechanism, a clamping assembly and a load sensor. The elevating mechanism is connected to the gantry. The clamping assembly is moved by the elevating mechanism. The clamping assembly has a predetermined clamping quantity. The load senor is connected to the clamping assembly. The controller is electrically connected to the clamping device. The predetermined clamping quantities are different. The controller controls the elevating mechanism to move the clamping assembly along a height direction, thereby allowing the clamping assembly to clamp a material. The controller obtains a real clamping quantity based on the feedback of the load sensor. The controller controls at least one of the clamping assemblies to release the material, thereby obtaining a real material quantity. The real material quantity is equal to or larger than a predetermined material quantity. Therefore, a material with a specific quantity is obtained. |
