Clamp machine head for clamping silicon slices

Abstract

The invention discloses a clamp machine head for clamping silicon slices, and belongs to the technical field of silicon slice cleaning. The clamp machine head comprises a base, two driving rods and two connecting rods are arranged in the base in a penetrating manner, driving blocks are connected at the left ends of the two driving rods, the left diameters of the two connecting rods are gradually decreased, supporting parts are arranged on the two driving blocks and is closely pressed on the two connecting rods under the action of reset mechanisms, the right ends of the two connecting rods areconnected with driving mechanisms, the driving mechanisms drive the two connecting rods to bilaterally slide, the distances among the supporting parts and center lines of the connecting rods are changed under the action of the reset mechanisms to drive the two driving rods to rotate, and the rotating directions of the two driving rods are opposite. According to the clamp machine head, wide-distance motion of the connecting rods is transformed into change of the distances among the supporting parts and the center lines of the connecting rods, the rotating accuracy of the driving rods is controlled, the rotating accuracy of clamping jaws is controlled, and the silicon slices are accurately clamped by the clamping jaws.

Description

technical field [0001] The invention belongs to the technical field of silicon wafer cleaning, in particular to a fixture head for clamping silicon wafers. Background technique [0002] In the traditional silicon wafer cleaning technology, the silicon wafers are usually placed in the silicon wafer cleaning flower basket for cleaning, but the silicon wafer cleaning flower basket has a certain shielding effect on the silicon wafers, resulting in incomplete cleaning of the silicon wafers, so it is necessary to rely on clamping Claws hold the wafer. Because the silicon wafer is thin and has high precision, the jaws must hold the silicon wafer accurately when clamping the silicon wafer. If the jaws hold the silicon wafer too tightly, it is easy to cause damage to the silicon wafer. If the wafer is clamped too loosely, it is prone to loose clamping. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provi...
