Description

Technical Field

[0001] The utility model relates to the technical field of equipment for processing quartz crystal wafers, and specifically refers to a tooling for screening quartz crystal wafers. Background Art

[0002] In the patent document with the application number CN201922199892.3, it discloses a tooling for screening quartz crystal wafers. Although it solves the problems of "in the traditional method of forming lumps, after the crystal wafers are ultrasonically cleaned and baked dry, the glass strips are manually selected, the efficiency is too low, and during the ultrasonic cleaning process, the collision between the quartz crystal wafers and the glass strips is likely to cause damage to the surface of the quartz crystal wafers, and the product quality is low". However, it still has the following deficiencies in use:

[0003] When in use, the gap between the bottom structures of adjacent two strips is fixed and unchanged, which results in that during use, one tooling can only meet the screening of quartz wafers of one thickness specification model, and the use limitation is relatively large and the practicability is relatively poor. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a tooling for screening quartz crystal wafers. When in use, the distance between adjacent two screening rods can be adjusted within a certain range, so as to be able to meet the screening of quartz wafers of different thickness specification models.

[0005] To solve the above technical problem, the technical solution provided by the utility model is as follows:

[0006] A tooling for screening quartz crystal wafers, including an outer wall cylinder, screening rods and a mounting seat; the screening rods are elliptical cylindrical rods, and a plurality of them are evenly arranged front and back, and there is a gap between adjacent screening rods. After the two ends of each screening rod are respectively installed and fixed on the same mounting seat, the gap size between adjacent two screening rods can be adjusted. The outer wall cylinder is a square cylinder structure, and after overlapping on the upper sides of a plurality of screening rods, it is installed and fixed between the two mounting seats.

[0007] As an improvement, the mounting seat is a rectangular frame structure, and the end part of the screening rod forms a lug plate that penetrates into the mounting seat;

[0008] It also includes handle screws; corresponding to the lug plates one by one, threaded holes are respectively opened on the top plate of the mounting seat for each handle screw. After the handle screws pass through the threaded holes, the corresponding lug plates are squeezed and fixed in the mounting seat. It is convenient to assemble and fix the mounting seat and the screening rods together.

[0009] As an improvement, the lower surface of the lug plate forms a first serrated surface, and the inner bottom surface of the mounting seat forms a second serrated surface, and the first serrated surface meshes with the second serrated surface. It can make the assembly between the mounting seat and the screening rod more firm.

[0010] As an improvement, ear plates are respectively fixed on the left and right sides of the bottom of the outer wall cylinder, and the ear plates are fixed on the upper side plates of the mounting seats on the same side by screws, which facilitates the assembly and fixation of the outer wall cylinder and the mounting seats together.

[0011] The advantages of the present utility model compared with the prior art are as follows:

[0012] When the present utility model is in use, through the cooperation of the outer wall cylinder and the screening rods fixedly arranged at its bottom, the quartz wafers can be screened conveniently and efficiently; at the same time, the gap size between adjacent two screening rods is adjustable. After adjusting the gap size, the present novel can screen quartz wafers of different thickness specifications and models, with less use limitations and stronger practicability.

[0019] The following further elaborates on the present utility model in conjunction with the attached drawings.

[0020] A tooling for screening quartz crystal wafers, comprising:

[0021] An outer wall cylinder 1, with tooling hooks respectively fixed on the left and right side walls thereof, ensuring that the tooling in this embodiment can be suspended in a cleaning basket during the process of ingot processing. The above is the prior art described in the above-mentioned comparative document. The difference is that in this embodiment, the outer wall cylinder 1 is designed as a square cylinder structure;

[0022] Screening rods 2, a mounting seat 3 and handle screws 5; the screening rods 2 are elliptical cylindrical rods, and seven are evenly arranged in the front and back, and there are gaps between adjacent screening rods 2. The mounting seat 3 is a rectangular frame structure. The ends of the screening rods 2 form lug plates 4 that penetrate into the mounting seat 3, corresponding to the lug plates 4 one by one. Threaded holes are respectively opened on the top plate of the mounting seat 3 corresponding to each handle screw 5. After the handle screw 5 passes through the threaded hole, the corresponding lug plate 4 is squeezed and fixed in the mounting seat 3. A first serrated surface 6 is formed on the lower surface of the lug plate 4, and a second serrated surface 7 is formed on the inner bottom surface of the mounting seat 3. The first serrated surface 6 meshes with the second serrated surface 7. Support feet (not shown in the figure) are respectively fixed at both ends of the bottom of the mounting seat 3, facilitating the stable placement of this tooling;

[0023] The outer wall cylinder 1 is lapped on the upper sides of a plurality of screening rods 2. Ear plates 8 are respectively fixed on the left and right sides of the bottom of the outer wall cylinder 1, and the ear plates 8 are fixed on the upper side plate bodies of the mounting seat 3 on the same side through screws 9. As a preferred embodiment, a pair of ear plates 8 are respectively arranged in a front-back mirror image on the left or right side of the outer wall cylinder 1.

[0024] In the specific implementation of this embodiment: During the process of ingot processing of quartz crystal wafers, the tooling in this embodiment is used in cooperation with a cleaning basket with an outer diameter of 135 mm and a depth of 85 mm. The tooling is placed in the cleaning basket, and the ingots to be processed are placed therein. During the cleaning process, the operator uses this tooling to perform 2 to 3 times of pure water cleaning on the quartz crystal and gently shakes it. The quartz crystal wafers fall into the cleaning basket through the gaps between adjacent screening rods 2, and all the glass strips are screened out.

[0025] After loosening the handle screw 5, the size of the gap between adjacent screening rods 2 can be adjusted, so that the tooling for screening quartz crystal wafers can be applicable to screening quartz wafers of different thickness specifications.

[0026] The above has described the present utility model and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural manners and embodiments to this technical solution without creative efforts, they shall all fall within the protection scope of the present utility model.
