Description

Technical Field

[0001] The utility model relates to an optical element manufacturing technology in the optical communication industry, in particular to a liquid dripping device used in the grinding and polishing process of optical glass. Background Art

[0002] In the optical communications industry, the grinding and polishing of optical glass are crucial process steps that directly impact the performance, reliability, and lifespan of optical components. Optical glass requires high-precision surface treatment to ensure minimal light transmission loss and accurate reflection and refraction. Therefore, improving the efficiency and accuracy of optical glass surface treatment is crucial for the optical communications industry.

[0003] In the traditional optical glass grinding and polishing process, grinding liquid or polishing liquid is usually dripped onto the surface of the optical glass manually or semi-automatically. This method is not only inefficient, but also difficult to ensure the uniformity of the distribution of the grinding liquid or polishing liquid, thus affecting the quality of the optical glass surface. In addition, due to differences in operator skill levels, it may also lead to fluctuations in product quality.

[0004] To address these issues, the industry has begun exploring the use of automated dripping devices. While existing dripping devices have improved grinding and polishing efficiency to a certain extent, they still have some drawbacks, such as high cost; uneven dripping, which can easily cause scratches or defects on the optical glass surface; and complex operation, requiring high operator skills. Summary of the Invention

[0005] The technical problem to be solved by the utility model is to provide a liquid dripping device for the optical glass grinding and polishing process with a simple structure and uniform liquid dripping, which can stir the grinding liquid or polishing liquid to ensure high-quality grinding and polishing operations, and can flexibly control the dripping speed.

[0006] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a dripping device for optical glass grinding and polishing process, comprising a height adjustment frame and a dripping pot, the dripping pot is fixedly installed on the height adjustment frame, the height adjustment frame is used to adjust the height of the dripping pot, the top of the dripping pot is detachably fixedly provided with a liquid adding cover, the liquid adding cover is fixedly provided with a liquid adding column and an electric rotating mechanism, the interior of the liquid adding column is penetrated by a liquid adding hole connected with the interior of the dripping pot in the up and down directions, the bottom of the electric rotating mechanism is fixedly connected with a stirring rod downward, the stirring rod passes downward through the liquid adding cover and extends to below the middle of the inner cavity of the dripping pot, the electric rotating mechanism is used to control the rotation of the stirring rod, the bottom of the dripping pot is fixedly provided with a dripping tube with a flow rate control mechanism, and the interior of the dripping tube is provided with a dripping hole connected with the interior of the dripping pot.

[0007] Compared with the prior art, the advantage of the present invention is that the unstirred grinding liquid or polishing liquid prepared in proportion is added to the dripping pot through the liquid adding column through the liquid adding hole. At this time, the electric rotation mechanism drives the stirring rod to rotate automatically, and continuously and automatically stirs the solution inside the dripping pot evenly to prevent powder precipitation during the grinding or polishing process. During stirring, the dripping tube is closed by the flow rate control mechanism. After stirring is completed, the dripping tube is opened by the flow rate control mechanism and drips at a set flow rate to a fixed position on the grinding disc or polishing disc, thereby ensuring high-quality grinding or polishing operations. At the same time, the dripping speed can be flexibly controlled as needed; the entire device has a simple structure, is easy to manufacture and has a low cost, the dripping process is stable, and can effectively ensure the uniformity of the grinding liquid or polishing liquid, thereby improving the quality of the optical glass surface.

[0008] Specifically, the electric rotation mechanism includes a motor mount, a rotary motor, and a motor controller. The motor mount and the motor controller are respectively fixedly mounted on the top of the liquid filling cap. The rotary motor is fixedly positioned downwardly within the motor mount. The rotary portion of the rotary motor is fixedly coaxially connected to the upper end of the stirring rod. The motor controller is used to control the rotation of the rotary motor. In this device, the rotary portion of the rotary motor and the upper end of the stirring rod are fixed with tape, but can also be fixedly connected using a specialized coupling device. The rotary motor drives the stirring rod to continuously and automatically rotate, continuously stirring the added grinding liquid or polishing liquid, ensuring the uniformity of the dripping grinding liquid or polishing liquid, thereby improving the quality of the optical glass surface.

[0009] Specifically, the height adjustment frame includes a fixed base, a vertical support rod, and a fixed cross bar. The fixed base is used to be fixedly installed on a work surface. The vertical support rod is vertically fixed on the fixed base. The fixed cross bar is movably fixed horizontally on the vertical support rod via a cross connection block with a locking nut. A fixing ring for placing the dripping pot is fixed horizontally on the fixed cross bar. The upper part of the dripping pot forms an inverted cone-shaped fixing portion with a larger upper part and a smaller lower part. The bottom of the inverted cone-shaped fixing portion is fixedly mounted on the fixing ring. The structure is simple and easy to assemble. After assembly, the position of the dripping pot is fixed, ensuring the stability of the dripping process and improving the product quality consistency of the processed optical glass.

[0010] Preferably, the lower side of the dripping pot forms an inverted cone structure that is wide at the top and narrow at the bottom. The bottom of the dripping pot is fixedly provided with a connecting column that is internally connected to the interior of the dripping pot. The dripping tube is fixedly sleeved on the outer side of the connecting column. The flow rate control mechanism is a dripping speed regulator, which is clamped on the dripping tube. The inverted cone structure can ensure that the internal solution of the dripping pot is concentrated downward, ensure the uniformity of the stirred grinding liquid or polishing liquid, and make the dripping process smoother, and the remaining grinding liquid or polishing liquid will not be excessively wasted. The dripping speed regulator is a conventional flow rate control device. The clamping degree of the dripping tube is adjusted by manually adjusting the pulley position of the dripping speed regulator to control the internal flow rate of the dripping tube. When in use, the dripping speed is pre-set by the dripping speed regulator, so that during the actual grinding or polishing operation, the grinding liquid or polishing liquid can be dripped onto the fixed position of the grinding disc or polishing disc at the set dripping speed, thereby ensuring high-quality grinding or polishing operation.

[0011] Preferably, the diameter of the drip hole is in the range of 3 to 6 mm. This value is set accordingly according to the actual needs of the grinding or polishing operation, and can be adapted to different optical glass products by replacing the drip tube with different drip hole diameters.

[0012] Furthermore, the bottom of the dripping pot is fixedly provided with a threaded connector surrounding the outer side of the connecting column. A hollow threaded fixing sleeve is fixedly screwed onto the threaded connector. A positioning rod is fixedly provided downwardly from the bottom of the threaded fixing sleeve. The lower end of the dripping tube is fixedly connected to the positioning rod. The dripping tube is generally bound to the positioning rod with tape to prevent the dripping tube from shaking during dripping, thereby ensuring the stability of the dripping. When the dripping pot needs to be cleaned, the liquid filling cap on the top of the dripping pot and the threaded fixing sleeve at the bottom can be removed separately, and the interior of the dripping pot can be cleaned using common cleaning tools such as a cleaning brush.

[0013] Preferably, the bottom of the stirring rod is an inverted trapezoidal frame that is wide at the top and narrow at the bottom. The bottom shape of the stirring rod can also be any other shape with a certain width, such as L-shaped, T-shaped, "mountain" shaped, "mouth" shaped, etc., so as to improve the stirring efficiency.
