Description

Technical Field

[0001] This utility model relates to the field of electronic glass polishing technology, and in particular to a polishing device with polishing liquid recycling function. Background Technology

[0002] Polishing the glass lenses of consumer electronics products such as mobile phones and tablets is a precision manufacturing process. Its core objective is to remove microscopic scratches and subsurface damage layers remaining from the cutting or grinding stages, ultimately achieving extremely high surface smoothness, gloss, and optical performance. This process typically involves using specialized equipment to move the lens relative to a polishing disc under pressure, achieving ultra-precise removal of material surface imperfections with the aid of an intermediate medium.

[0003] The intermediate medium is a polishing slurry, which is a functional suspension containing ultrafine abrasive particles dispersed in a water-based or oil-based liquid. This liquid not only acts as a carrier for the abrasive, uniformly delivering particles with cutting ability to the polishing interface, but its chemical composition also often plays a role in softening the glass surface and promoting the removal of materials through chemical mechanical polishing. At the same time, it provides lubrication, cooling, and removes polishing debris, working together to achieve the nanoscale smooth surface, high light transmittance, excellent strength, and smooth touch required for the lens.

[0004] In traditional equipment, the water pump in the grinding tank draws out the grinding liquid and delivers it to the polishing machine. After the polishing machine is used, the grinding liquid flows back to the filter plate on the grinding tank. After being filtered by the filter plate, it flows back into the grinding tank for reuse. The grinding liquid in the grinding tank remains in a static state throughout the entire cycle.

[0005] However, certain problems exist during use. For example, the grinding liquid is in a static state inside the grinding tank, but the grinding liquid is a mixture of water and grinding powder. The density and specific gravity of grinding powder are greater than that of water. Prolonged static state easily leads to separation and sedimentation. After sedimentation, a large amount of sludge is generated at the bottom of the grinding tank, causing blockage of the water pump. Furthermore, prolonged sedimentation reduces the concentration of the grinding liquid, making it difficult for production operators to accurately control the concentration, easily leading to misjudgments of product quality and the generation of numerous defective products such as those that are not fully ground, scratched, or have grinding marks. It also increases the amount of grinding liquid added, resulting in material waste. On the other hand, the sedimentation of the grinding liquid requires frequent cleaning of the grinding tank, increasing labor intensity. Therefore, we urgently need a polishing equipment with a polishing liquid recycling function to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problems in the prior art where prolonged standing in the grinding tank leads to grinding powder sedimentation, clogging of the water pump, and a decrease in the concentration of grinding water. Therefore, this invention proposes a polishing device with a polishing liquid recycling function.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A polishing device with polishing fluid recycling function includes a frame and a grinding hopper mounted on the frame. It also includes: a water pump pipe disposed in the grinding hopper for communication with a polishing machine; an impact pipe disposed on the water pump pipe; the impact pipe mainly consists of an inlet section and an impact section; the inlet section is fixedly connected to the middle section of the water pump pipe; a regulating valve for controlling the flow rate is fixedly installed on the impact section; and a filter plate fixedly installed on the inner wall of the grinding hopper for discharging impurities.

[0008] In order to transfer the grinding water to the polishing machine, preferably, a water pump is fixedly connected to the inner wall of the grinding barrel away from the filter plate. The input end of the water pump is perpendicular to the bottom wall of the grinding barrel, and the output end of the water pump is fixedly connected to the corresponding port of the water pumping pipe to form a transmission channel.

[0009] To improve the transmission of water for grinding, the angle between the axis of the water pump and the bottom wall of the grinding tank is further defined as 30°-60°.

[0010] To improve the impact effect, preferably, the water inlet section and the impact section form a bent structure, and the water inlet section and the impact section are interconnected, with the included angle between the axis of the water inlet section and the axis of the impact section ranging from 90° to 135°.

[0011] To provide a stable water absorption area, preferably, the distance between the input end of the water pump and the bottom wall of the grinding drum is within 1 / 5 of its total height.

[0012] To improve the filtration effect, preferably, the filter plate is made of 304 stainless steel mesh, and polyester fiber non-woven fabric is detachably installed on the filter plate.

[0013] Compared with the prior art, this utility model provides a polishing device with polishing slurry recycling function, which has the following beneficial effects: 1. This polishing equipment with polishing fluid recycling function, through the setting of the impact pipe, allows the grinding water to impact the bottom wall of the grinding tank at the optimal angle, ensuring both concentrated impact force and expanded impact range. The regulating valve installed on the impact pipe can flexibly adjust the impact flow and pressure to adapt to the bottom wall cleaning needs under different working conditions, effectively cleaning residual impurities on the bottom wall, avoiding accumulation, and keeping the state of the grinding fluid continuously stable. It increases the floating state of the grinding water, reduces the risk of dry polishing caused by sedimentation, lack of water, and insufficient grinding concentration due to prolonged lack of agitation of the grinding water, and improves the product production precision.

[0014] 2. This polishing equipment with polishing fluid recycling function can reduce the cleaning time and frequency of the grinding barrel, reduce labor intensity, and maintain a constant grinding concentration, further reducing the labor intensity of operators. It is also easier for operators to grasp the status of the grinding fluid, thus optimizing the operation process.

[0015] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model achieves stable production of the polishing machine by adding a return water impact pipe, thereby improving the polishing machine's operating rate, work efficiency, and operational stability, and achieving the goal of reducing costs and increasing benefits.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] Example: Reference Figures 1-4A polishing device with polishing fluid recycling function includes a frame 1 and a grinding hopper 2 installed on the frame 1, wherein the grinding hopper 2 is used to hold grinding water.

[0021] It also includes a water pipe 3 installed in the grinding barrel 2 for communication with the polishing machine. The angle between the axis of the water pipe 3 and the bottom wall of the grinding barrel 2 is in the range of 30°-60°. A water pump 7 is fixedly connected to the inner wall of the grinding barrel 2 away from the filter plate 6. The input end of the water pump 7 is perpendicular to the bottom wall of the grinding barrel 2, and the output end of the water pump 7 is fixedly connected to the corresponding port of the water pipe 3 to form a transmission channel. The distance between the input end of the water pump 7 and the bottom wall of the grinding barrel 2 is in the range of 1 / 5 of its total height. Here, the water pump 7 is used to extract grinding water. The distance between the input end of the water pump 7 and the bottom wall of the grinding tank 2 is 1 / 5 of the height of the grinding tank. For example, if the grinding tank 2 is 1.8m high, the distance between the input end of the water pump 7 and the bottom wall of the grinding tank 2 is about 0.4m. This distance setting can avoid sucking in impurities that settle on the bottom wall, while ensuring stable water suction efficiency and improving the operational stability of the circulation system.

[0022] Furthermore, the water pump 3 is a straight pipe structure, with one end fixedly connected to the output end of the water pump 7, and the other end extending upwards to the outside of the grinding barrel 2 for connection with the polishing machine. The inclination angle of the water pump 3 to the horizontal plane is preferably 45°. This angle setting reduces the frictional resistance during the transmission of grinding water, significantly improves the transmission speed of grinding water, and ensures circulation efficiency.

[0023] An impact pipe 4 is installed on the pumping pipe 3. The impact pipe 4 is mainly composed of an inlet section and an impact section. The inlet section is fixedly connected to the middle section of the pumping pipe 3. A regulating valve 5 for controlling the flow rate is fixedly installed on the impact section. The inlet section and the impact section form a bent structure and are connected to each other. The included angle between the axis of the inlet section and the axis of the impact section is in the range of 90°-135°. Here, the regulating valve 5 is a manual shut-off valve or a solenoid regulating valve, used to regulate the flow rate and pressure of the grinding water in the inlet section of the impact pipe 4, so as to achieve flexible control of the impact force on the bottom wall. Furthermore, the inlet section of the impact pipe 4 is connected to the middle of the pumping pipe 3. The impact pipe 4 is a one-time bent structure, and the angle between the central axis of its inlet section and outlet section is preferably 120°. At this angle, the grinding water impacts the bottom wall of the grinding tank 2 at the optimal angle, which not only ensures the impact force is concentrated but also expands the impact range. In addition, the regulating valve 5 installed on the impact pipe 4 can flexibly adjust the impact flow rate and pressure to adapt to the bottom wall cleaning needs under different working conditions, effectively cleaning the residual impurities on the bottom wall and avoiding accumulation.

[0024] A filter plate 6 for discharging impurities is fixedly installed on the inner wall of the grinding barrel 2. The filter plate 6 is made of 304 stainless steel mesh, and a polyester fiber non-woven fabric 8 is detachably installed on the filter plate 6.

[0025] Here, the filter plate 6 uses a mesh size of 80-120, and the polyester fiber nonwoven fabric 8 has a thickness of 2mm. The filter plate 6 provides structural support, and the polyester fiber nonwoven fabric 8 improves the filtration accuracy.

[0026] Furthermore, stainless steel mesh provides good structural strength and corrosion resistance, while polyester fiber nonwoven fabric 8 has high filtration accuracy, which can effectively intercept particulate impurities in grinding water, improve filtration effect, and extend the service life of the circulation system.

[0027] In this invention, grinding water is poured into the grinding tank 2, and the water pump 7 is started. The input end of the water pump 7 is 0.4m away from the bottom wall to stably draw the filtered grinding water. It is efficiently transmitted through the 45° inclined water pipe 3. Part of the grinding water is transmitted through the 120° bent impact pipe 4. The impact flow rate is changed by the regulating valve 5 to achieve controllable impact on the bottom wall. After the grinding water enters the polishing machine, it naturally flows back to the grinding tank 2. After being filtered by the filter plate 6 and the polyester fiber non-woven fabric 8, it is then drawn out by the water pump 7 to achieve circulation.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
