Description

Sand blasting protection clamping device and sand blasting method for alumina ceramic Pin needle Technical Field The invention relates to the technical field of semiconductor sand blasting, in particular to an aluminum oxide ceramic Pin needle sand blasting protection clamping device and a sand blasting method. Background In the high-precision industrial fields of semiconductor packaging, lithium battery cell preparation, high-temperature heat treatment and the like, the metal Pin needle has the defects of conductive short circuit, high-temperature deformation and metal scraps, and cannot meet the clean and insulating process requirements. The ceramic Pin needle becomes a core positioning and limiting component due to the advantages of high insulativity, high temperature resistance, chemical inertness and the like. The conventional aluminum oxide ceramic Pin needles are mostly of pure cylindrical structures, circumferential rotation is easy to occur in automatic high-frequency operation, so that the positioning accuracy of a workpiece is offset, and therefore, part of the Pin needles can be subjected to shape fine adjustment according to the actual use scene of equipment, and the method comprises the steps of adding a section of special-shaped (such as triangle, quadrangle and the like) characteristic of the section of the end part of the Pin needle, arranging two parallel planes on the cylindrical wall and the like. While the parallel planes are additionally arranged on part of the improved Pin needles to realize anti-rotation, most of the planes are polished or common grinding surfaces, the defect of insufficient contact friction force exists, loose displacement easily occurs under the high-frequency vibration working condition of equipment, and the Pin needles cannot be adapted to the scenes with severe requirements on stability such as semiconductor wafer positioning, limit of lithium battery lugs and the like. Therefore, after the characteristics of the parallel contact surfaces are added, a certain roughness treatment is performed on the parallel surfaces, so that the contact friction force of the two surfaces is increased. In order to increase the contact friction at the parallel-face feature, it is often necessary to increase the roughness at both of these points. In the production process of such products, a sand blasting process is often added, and sand blasting is performed on planar features. At the same time, the portions other than the planar features need to be kept low in roughness after polishing. This is mainly to ensure the high precision guiding or positioning requirements, the clean and low wear requirements, the insulation and corrosion resistance strengthening requirements of Pin needles. Therefore, when the ceramic Pin needle is used for sand blasting, not only can the clamping be stable, but also the non-sand-blasted surface needs to be protected in all aspects. In order to improve the machining efficiency, the prior art discloses a batch machining fixture for PIN needle parts, for example, CN 217800292U discloses a batch machining fixture for PIN needle parts, and a plurality of PIN needle parts can be machined through one-time clamping, so that the machining efficiency of the PIN needle parts is greatly improved. However, the clamp can realize batch clamping, but cannot meet the requirement of sand blasting. In order to tightly attach the shape outline of a product, ensure that the product is stable in the sand blasting process and only the sand blasting surface is exposed, the industry commonly uses ceramics made of the same material to process a half clamping jig, the half product is processed according to the outline of the product, then the jig is closed, the product is wrapped in the jig, only the sand blasting surface is exposed, and finally, the two flaps are fixed by using an adhesive tape or an elastic clamp and the like, but the method has higher cost, faster abrasion and low efficiency. Disclosure of Invention The invention aims to solve the problems of inconvenient operation, high cost, low efficiency and the like in the prior art when a PIN needle anti-rotation surface is sandblasted, and provides an alumina ceramic Pin needle sandblast protection clamping device and a sandblast method. The technical scheme includes that the aluminum oxide ceramic Pin needle sand blasting protection clamping device comprises a clamping device body, wherein the clamping device body comprises a protection seat, a support base and a sand blasting cover plate, the support base and the sand blasting cover plate are arranged in the protection seat, a plurality of Pin needle clamping positioning structures are arranged on the support base, and a plurality of sand blasting openings are formed in the sand blasting cover plate. This sand blasting protection clamping device of aluminium oxide pottery Pin needle, this clamping device main part is when using, cooperate with sand blasting equipment
