Each grinding mechanism comprises a reciprocating device, a sliding block, a pressure sensor and an arc-shaped grinding assembly, wherein the reciprocating device is fixed to the cross beam, the sliding block is slidably connected with the corresponding grindingguide rail, and the reciprocating device drives the sliding block to reciprocate on the corresponding grinding guide rail; the top of the pressure sensor is fixedly connected with the sliding block, and the bottom of the pressure sensor is fixedly connected with the arc-shaped grinding assembly; and the arc-shaped grinding assembly is arranged above the integrated circuit chip. A chip fixing mechanism is arranged at the inner bottom of the rack. The integrated circuit chip is fixedly placed on the chip fixing mechanism. According to the high-precision automatic removing machine, the grinding pressure is measured through the pressure sensors, and then the working pressure and reciprocating frequency of the arc-shaped grinding assemblies are accurately controlled, so that the adhesive removal effect is effectively ensured, and the production efficiency is improved.
