Description
Technical Field
[0001] The utility model relates to the technical field of ceramic ring equipment, in particular to a ceramic ring used for precision environmental protection equipment. Background Art
[0002] Wafer refers to the silicon wafer used to make silicon semiconductor integrated circuits. Its original material is silicon. High-purity polycrystalline silicon is dissolved and then mixed with silicon crystal seeds, and then slowly pulled out to form cylindrical single crystal silicon. After grinding, polishing and slicing, the silicon crystal rod forms a silicon wafer, that is, a wafer. At present, domestic wafer production lines are mainly 8 inches and 12 inches. The main processing methods of wafers are sheet processing and batch processing, that is, processing one or more wafers at the same time. As the feature size of semiconductors becomes smaller and smaller, the processing and measurement equipment becomes more and more advanced, resulting in new data characteristics in wafer processing. At the same time, the reduction in feature size increases the impact of the number of particles in the air on the quality and reliability of the wafer after processing during wafer processing. As the cleanliness improves, the number of particles also shows new data characteristics. Ceramic rings are fixed clamping devices used to fix semiconductor wafers.
[0003] The pressing edge of the pressing ring in the prior art is often fixedly mounted with the pressing ring base, but the pressing edge of the pressing ring is often damaged before the pressing ring base during use, resulting in the pressing ring base having to be scrapped before reaching the end of its service life due to damage to the pressing edge of the pressing ring, which not only affects the overall service life of the equipment, but also increases the cost of equipment replacement;
[0004] To this end, we propose a ceramic ring for precision environmental protection equipment to solve the problem that after the pressing edge of the ceramic ring is damaged, the entire ceramic ring will be scrapped, thereby increasing the cost of equipment replacement. Utility Model Content
[0005] The purpose of the utility model is to provide a ceramic ring for precision environmental protection equipment to solve the problems raised in the above background technology.
[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a ceramic ring for precision environmental protection equipment, comprising a main structure, the main structure comprising a ceramic base, a mounting groove is provided at the bottom of the ceramic base, a ceramic stabilizing ring is arranged inside the mounting groove; a pressing edge is fixedly connected to the outer wall of the ceramic stabilizing ring, and an installation fixing ring is provided at the bottom of the ceramic base.
[0007] Preferably, a mounting adapter hole is provided at the bottom of the ceramic base, a threaded hole is provided on the outer surface of the mounting fixing ring, and the size and shape of the mounting adapter hole are adapted to the threaded hole.
[0008] Preferably, a fixing groove is provided on the outer wall of the ceramic stabilizing ring, and a fixing block is arranged inside the fixing groove.
[0009] Furthermore: the top of the fixing block is semicircular, and the semicircular fixing block is more convenient to be inserted into and disengaged from the positioning groove, so as to facilitate the installation and removal of the ceramic stabilizing ring.
[0010] Preferably, a return spring is fixedly connected to the inner bottom wall of the fixing groove, and the top of the return spring is fixedly connected to the bottom of the fixing block.
[0011] Preferably, the inner wall of the ceramic base is provided with equidistant positioning grooves, and the size and shape of the positioning grooves are adapted to the fixing block.
[0012] Preferably, the outer wall of the ceramic base is annularly and fixedly connected with mounting ears, and the number of the mounting ears is three.
[0013] Preferably, a rubber pad is fitted on the inner wall of the installation groove, and a through hole with a size and shape matching the positioning groove is opened on the outer surface of the rubber pad.
[0014] Compared with the prior art, the beneficial effects achieved by the utility model are:
[0015] First, the utility model installs the ceramic stabilizing ring into the installation groove of the ceramic base. When the ceramic stabilizing ring is installed, the fixing block in the fixing groove is squeezed and retracted into the fixing groove. The ceramic stabilizing ring is rotated to align the fixing groove with the positioning groove. The reset spring gives the fixing block an outward force to make the fixing block disengage from the fixing groove and snap into the positioning groove, so that the ceramic stabilizing ring and the pressing edge are fixed on the ceramic base. The installation fixing ring is fixed to the bottom of the ceramic stabilizing ring through the installation adapter hole at the bottom of the ceramic base, thus completing the installation of the ceramic stabilizing ring. When the pressing edge of the ceramic ring is damaged during use, the pressing edge can be replaced by disassembling the ceramic stabilizing ring, thereby avoiding the entire ceramic ring being scrapped due to damage to the pressing edge of the pressing ring of the ceramic ring, thereby reducing the cost of equipment replacement.
[0016] Second, the utility model facilitates fixing the ceramic ring on the equipment through the mounting ears. The three mounting ears make the ceramic ring more stable on the equipment. The rubber pad reduces the shaking of the ceramic stabilizing ring in the ceramic base and reduces the squeezing force of the pressing edge, thereby reducing the damage of the pressing edge to a certain extent.
