Description

Wafer positioning plate with information code Technical Field The utility model relates to the technical field of resonator wafer processing accessories, in particular to a wafer positioning plate carrying information codes. Background Wafers for resonators are typically processed through multiple processes during production, and each process requires registration. At present, a common recording mode is to spray corresponding information codes on the surface of a positioning plate for loading wafers, and record the processing data of the wafers by scanning the information codes. However, in the long-time use process, the positioning plate is continuously contacted with various solutions and the surface of the positioning plate is also continuously rubbed, so that the information code is corroded and worn incompletely in a short time, and the information code cannot record the information of the wafer. Meanwhile, the erosion and abrasion are likely to occur at any time, so that the information of the wafer in the processing process is easy to lose, the corresponding locating plate is required to be stopped, the information code is sprayed again, and the processing is interrupted, so that the problem needs to be solved. Disclosure of utility model In order to avoid and overcome the technical problems in the prior art, the utility model provides a wafer positioning plate carrying information codes. The utility model can effectively prolong the service time of the information code. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a wafer locating plate that carries information sign indicating number, includes the constant head tank of seting up on the locating plate, the rigid coupling has the potsherd in the constant head tank, is provided with the information sign indicating number on the upper surface of potsherd, and the upper surface of potsherd is less than the notch of constant head tank. As a further scheme of the utility model, a plurality of liquid inlets are formed on the bottom of the positioning groove in a penetrating way. As a still further proposal of the utility model, each liquid inlet is evenly distributed on the bottom of the positioning groove. As a still further proposal of the utility model, the positioning groove is in a cuboid shape. As a still further proposal of the utility model, each liquid inlet is distributed in a rectangular array. As a still further proposal of the utility model, the notch of the positioning groove is provided with a notch which can guide the insertion of the pry bar to raise the ceramic plate. As a still further proposal of the utility model, the ceramic plate is fixedly arranged in the positioning groove by means of gluing. As a still further proposal of the utility model, the ceramic plate is in a cuboid shape with a positioning groove matched with the ceramic plate. As a still further proposal of the utility model, the four corners of the ceramic plate are rounded corners. As a still further aspect of the utility model, the information code is provided on the upper surface of the ceramic sheet by spraying or imprinting. Compared with the prior art, the utility model has the beneficial effects that: 1. The information code is arranged on the ceramic chip and fixedly connected in the positioning groove, and the upper surface of the ceramic chip is lower than the notch of the positioning groove, so that the information code is effectively prevented from being directly exposed, the damage risk caused by external friction, corrosion and other factors is reduced, the service time of the information code is obviously prolonged, and the long-term readability of the information is ensured. 2. A plurality of liquid inlets are formed in the bottom of the positioning groove in a penetrating mode, and liquid is allowed to flow into the positioning groove from the bottom of the positioning groove through the design. In the process of sol, liquid can quickly reach all positions in the positioning groove, so that the colloid between the ceramic sheet and the positioning groove is quickly dissolved, and the speed of taking out the ceramic sheet from the positioning groove is further increased. 3. Each feed liquor hole evenly distributed is in the constant head tank bottom for liquid can more evenly disperse when flowing into the constant head tank, avoids the too much or too little condition of local regional liquid, ensures that everywhere in the constant head tank can all obtain unanimous processing, improves stability and the reliability of whole treatment effect. 4. The locating groove is designed into a cuboid shape, the shape is simple and regular, the processing and the manufacturing are easy, and the production difficulty and the cost are reduced. Meanwhile, the cuboid shape can be better matched with a cuboid wafer to be positioned, stable supporting and positioning functions are
