Description

Technical Field

[0001] The utility model relates to the field of crystal grinding, in particular to a crystal grinding and polishing integrated device. Background Art

[0002] Abrasive fluid is a highly efficient abrasive material made by uniformly dispersing abrasive particles in a liquid or gaseous medium. Its excellent chemical and mechanical properties make it widely used in the grinding and polishing of materials such as silicon wafers, compound crystals, precision optical devices, liquid crystal panels, crystals, and metal workpieces.

[0003] Abrasive particles are the soul of the grinding fluid. Factors such as their type (e.g., diamond, silicon carbide, aluminum oxide), particle size, and morphology directly influence the grinding effect. Generally speaking, higher abrasive hardness and larger particle size result in stronger cutting forces and higher machining efficiency, but also greater surface roughness. Conversely, lower abrasive hardness and smaller particle size result in smoother surfaces but lower machining efficiency. Furthermore, the shape of the abrasive particles (e.g., spherical, irregular) also influences their performance during machining.

[0004] As a carrier for abrasive particles, the medium not only effectively disperses them but also cools the workpiece, removes grinding debris, and lubricates the particles. Different processing materials and process requirements dictate different medium properties (such as viscosity, pH, and polarity). Some media also exhibit chemical effects that can accelerate material removal.

[0005] Crystal grinding and polishing is a crucial process in the grinding process, but traditional methods suffer from two significant issues. First, when switching between grinding fluids of varying particle sizes, the lack of effective collection and recovery methods often results in waste. This waste fluid, containing high-value abrasives, is either discarded or contaminated and cannot be reused, resulting in both resource waste and increased production costs. Second, due to the abrasive's tendency to crystallize and precipitate, this tendency leads to uneven distribution during the extraction and polishing process, resulting in substandard crystal polishing processes. This crystallization also causes the abrasive to aggregate into large particles, which can scratch the crystal during production, rendering it scrapped and impacting product yield. Utility Model Content

[0006] In order to overcome the lack of effective collection and recovery methods in the existing technology, which often results in waste of grinding fluid and the grinding fluid is easy to crystallize and precipitate during use, resulting in poor grinding and polishing effect, the utility model provides an integrated crystal grinding and polishing equipment. By setting a grinding fluid recovery device, grinding fluids of different particle sizes are classified and recovered, thereby improving the circulation service life of the grinding fluid and reducing production costs.

[0029] It should be noted that the terms "first," "second," etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than those illustrated or described herein, and that the objects distinguished by "first," "second," etc. are generally of the same type, and do not limit the number of objects. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0030] It should be noted that, in the description of this application, the directions or positional relationships indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings.

[0031] It should be noted that, in the present application, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in the opposite order according to the functions involved. For example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.

[0032] The accompanying drawings illustrate an integrated crystal grinding apparatus comprising a frame 1, a grinding base 2 mounted on the frame 1, and a grinding assembly mounted within the grinding base 2. The grinding base 2 is the core component of the entire grinding process, providing a stable working platform.

[0033] The frame 1 also mounts an adjustment drive assembly 3, which includes a drive motor 31, a mounting bracket 32, and a hydraulic column 33. The drive motor 31 is secured to the frame 1 via the mounting bracket 32, and the movable end of the hydraulic column 33 is connected to the mounting bracket 32. The hydraulic column 33 can adjust the position of the mounting bracket 32.

[0034] The grinding assembly includes an upper grinding disc 41 and a lower grinding disc 42. The upper grinding disc 41 can be slidably arranged in the grinding seat 2. The upper end surface of the upper grinding disc 41 is fixedly connected to the output end of the drive motor 31. The bottom surface of the lower grinding disc 42 abuts against the inner bottom wall of the grinding seat 2. A cavity for grinding the workpiece is formed between the upper grinding disc 41 and the lower grinding disc 42.

[0035] The grinding seat 2 is connected to a drain pipe 43, and a grinding liquid recovery device is provided below the grinding seat 2. The grinding liquid recovery device is used to recover and process the grinding liquid.

[0036] In some embodiments, the grinding liquid recovery device includes a regulating valve 7, the water inlet of which is connected to the lower grinding plate 42. A plurality of parallel water tanks 55 are provided below the drain pipe 43, and the water outlet of the regulating valve 7 is connected to each of the plurality of water tanks 55. By switching the water outlets of the regulating valve 7, grinding liquids of different particle sizes are discharged into the corresponding water tanks 55, thereby preventing mixing of grinding liquids of different particle sizes.

[0037] A stirring motor 51 is fixed to the top of each water tank 55. The transmission shaft of the stirring motor 51 is fixedly connected to the extension rod 52. The stirring motor 51 drives the extension rod 52 to rotate around the axis of its transmission shaft. A crushing motor 53 is fixedly installed in the extension rod 52. The lower end of the extension rod 52 is connected to a stirring rod 54. The axis of the stirring plate 54 is perpendicular to the axis of the extension rod 52. The output end of the crushing motor 53 is connected to a driving gear 531. Two crushing rollers 542 are rotatably and symmetrically provided at both ends of the stirring rod 54. The ends of the two crushing rollers 542 that are close to each other are fixedly connected to a transmission gear 5421. The transmission gear 5421 is meshed with the driving gear 531. A filter screen 541 is fixed to the outer wall of the stirring rod 54. The stirring rod 54 is also provided with a through hole to allow liquid to enter the stirring rod.

[0038] The mesh size of the filter screen 541 on the stirring rod 54 is adjusted accordingly according to the particle size of the grinding liquid stored in the water tank 55 .

[0039] During actual use, the prepared grinding liquid is stored in the water tank 55, and the stirring motor 51 is turned on. The stirring motor 51 drives the extension rod 52 to rotate, and the extension rod 52 drives the stirring rod 54 fixed on the extension rod 52 to rotate. During this process, the crushing motor 53 drives the driving gear 531 to rotate, thereby driving the crushing roller 542 in the stirring rod 54 to rotate.

[0040] Furthermore, when the filter 541 rotates, the particles in the grinding liquid caught by the filter 541 that are larger than the mesh holes of the filter 541 will be pressed against the inner surface of the filter 541; at the same time, the crushing roller 542 continues to rotate, pressing over the particles pressed against the surface of the filter 541, so that the particles that have gathered into large particles on the surface of the filter 541 are crushed and turned into tiny particles that can pass through the mesh holes of the filter 541 and are released back into the grinding liquid.

[0041] The grinding liquid recovery device can fully stir the grinding liquid in the water tank 55 to avoid precipitation. At the same time, due to the easy crystallization of the grinding liquid, some grinding liquid crystals are crushed, thereby ensuring the stability and consistency of the grinding liquid use process.

[0042] In some embodiments, the polishing liquid recovery device further includes a polishing liquid circulation assembly, which includes a water pump 61. Multiple water tanks 55 are connected to the water pump 61 via connecting pipes, each of which is equipped with a solenoid valve. Through the cooperation between the water pump 61 and the solenoid valves, when any solenoid valve is in the on state, the other solenoid valves are in the closed state, ensuring a continuous and accurate supply of polishing liquid and preventing mixing of polishing liquids in different water tanks 55.

[0043] In some embodiments, the inner sidewall of the lower grinding disc 42 is provided with a spray hole 421 connected to a water pump 61. The grinding fluid sprayed from the spray hole 421 effectively cools the upper and lower grinding discs 41, 42, preventing excessive heat during the grinding process and protecting the workpiece and equipment. Furthermore, the spraying of the grinding fluid provides excellent lubrication, improving grinding efficiency and the finish of the workpiece surface.

[0044] In some embodiments, a water pump 61, a grinding assembly, spray holes 21, a drain pipe 43, and a water tank 55 form a reflux loop. The water pump 61 pumps the grinding liquid from the water tank 55 and delivers it to the spray holes 21 via a connecting pipe. The spray holes 21 then spray the grinding liquid onto the lower grinding plate 42. The grinding liquid provides cooling and lubrication during the grinding process and then flows back to the water tank 55 through the drain pipe 43, forming a circulation system. This recycling of the grinding liquid reduces the consumption of new liquid, lowering production costs and reducing resource waste.

[0045] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
