[0022] The polishing slurry supply device of this invention is a mechanical polishing slurry flow regulation and regular supply equipment with simple structure, convenient operation and low cost. In the field of polishing slurry supply technology, it can replace the complex control system of traditional pumps and programmable logic controllers, and achieve stable, accurate and economical polishing slurry supply in precision manufacturing fields such as semiconductor chip processing and precision optical lens grinding.
[0023] Specific references Figures 1-2As a specific embodiment of the polishing slurry supply device of this utility model, the polishing slurry supply device includes: a roller 110, a polishing slurry tank 120, a flow regulating valve 130, and a supply pipeline 140. This polishing slurry supply device is mainly composed of a roller 110, a polishing slurry tank 120, a flow regulating valve 130, and a supply pipeline 140. It realizes the full-process adaptation of polishing slurry from storage and precise flow control to stable delivery. The roller 110 drives the polishing slurry tank 120 to rotate and distribute the slurry evenly, the flow regulating valve 130 precisely controls the flow, and the supply pipeline 140 delivers the slurry in a directional manner, providing a stable and adjustable supply of polishing slurry for polishing operations.
[0024] Furthermore, such as Figure 1 As shown, the polishing slurry supply device consists of four core components: a roller 110, a polishing slurry tank 120, a flow regulating valve 130, and a slurry supply pipeline 140. These components form the basis for the overall functionality.
[0025] The roller mill 110 has a block structure, which provides stable support for the entire device and facilitates the integration of internal drive components, serving as the basic carrier for the stable operation of the device.
[0026] Furthermore, such as Figure 1 As shown, the block-shaped roller 110 can stably support the polishing liquid tank 120 at the top, providing a basic load for the operation of the device.
[0027] The polishing liquid tank 120 is a hollow cylindrical structure. A through hole is provided on one side of the polishing liquid tank 120, and a feed inlet is provided next to the through hole. The polishing liquid tank 120 is set on the top of the roller mill 110. The roller mill 110 is used to drive the polishing liquid tank 120 to rotate. The polishing liquid tank 120 is designed as a hollow cylindrical structure. A through hole is provided on one side for installing a flow regulating valve. A feed inlet is provided on the side for easy replenishment of liquid. When it is placed on the top of the roller mill 110, the two are in contact and close together. When the roller mill 110 is running, the friction between the top of the block structure and the bottom of the polishing liquid tank 120 is used to drive the polishing liquid tank to rotate synchronously, so that the polishing liquid in the tank flows regularly with the rotation. With the help of the device, the liquid supply process is completed, realizing the function of transmitting power through mechanical friction and making the polishing liquid uniform.
[0028] Furthermore, such as Figure 1 As shown, a hollow cylindrical polishing liquid tank 120 is placed on top of the drum machine 110. A through hole on one side is used to install a flow regulating valve 130. The feed port facilitates the replenishment of polishing liquid. The drum machine 110 can drive it to rotate so that the polishing liquid is evenly distributed.
[0029] The flow regulating valve 130 is installed through a through hole on one side of the polishing liquid tank 120. It can be directly installed through the through hole, allowing for close-range control of the polishing liquid flow rate, thus improving the accuracy of flow control and response speed.
[0030] Furthermore, such as Figure 1 As shown, the flow regulating valve 130 is installed through the through hole of the polishing liquid tank 120 to control the flow rate of the polishing liquid.
[0031] The liquid supply pipeline 140 has a rectangular structure and is located on one side of the roller mill 110. The rectangular structure makes it easy to fit the roller mill 110, reducing space occupation. Located on one side of the roller mill 110, it can stably receive the polishing liquid flowing out of the flow regulating valve 130 and transport it to the work area.
[0032] Furthermore, such as Figure 1 As shown, the liquid supply pipeline 140 has a rectangular structure and is installed on one side of the roller machine 110 for conveying polishing liquid.
[0033] In this embodiment, the flow regulating valve 130 includes an operating part, a connecting part, and an actuating part. The operating part is disposed outside the polishing liquid tank 120, and the connecting part is disposed on the polishing liquid tank 120 through a through hole. One end of the connecting part is connected to the operating part, and the actuating part is disposed inside the polishing liquid tank 120, with the other end of the actuating part connected to the operating part. The operating part is mounted outside the tank, the connecting part is connected to the operating part through the through hole, and the actuating part is placed inside the tank and connected to the connecting part, thus coordinating to achieve flow regulation.
[0034] In this embodiment, the operating unit includes a valve core mounting base 133, a valve core adjusting cover 134, a valve core rotating shaft 135, and a valve core rotating lever 136. The valve core mounting base 133 is a cylindrical structure with openings at both ends. The valve core adjusting cover 134 is a cylindrical structure with openings at both ends. One end of the valve core adjusting cover 134 is connected to one end of the valve core mounting base 133. The valve core rotating shaft 135 is a cylindrical structure. One end of the valve core rotating shaft 135 is disposed inside the other end of the valve core adjusting cover 134. The valve core rotating lever 136 is a cylindrical structure. The valve core rotating lever 136 is vertically disposed on the other end of the valve core rotating shaft 135. A cylinder of suitable size with openings at both ends is selected as the valve core mounting base 133 and the valve core adjusting cover 134. One end of the valve core adjusting cover 134 is fixed to one end of the valve core mounting base 133 by a spring pin 310. A cylindrical valve core rotating shaft 135 is taken, and one end is precisely inserted through the center hole of the other end of the valve core adjusting cover 134 to ensure that the shaft and cover are coaxial. Then, the cylindrical valve core rotating lever 136 is installed on the other end of the valve core rotating shaft 135 by vertical fastening, completing the assembly of the operating part. In use, rotating the lever drives the internal components to achieve flow regulation through the rotating shaft.
[0035] In this embodiment, the connecting part includes a valve body 131 and a valve core 132. The valve body 131 is a cylindrical structure with openings at both ends. One end of the valve body 131 is connected to the other end of the valve core mounting seat 133. The valve core 132 is a cylindrical structure with openings at both ends. The valve core 132 is disposed inside the valve body 131 and has a predetermined length. A cylindrical valve body 131 with openings at both ends and a cylindrical valve core 132 with openings at both ends of the same compatible specification are prepared. The valve core 132 has a predetermined length to match the flow channel requirements of the valve body 131. One end of the valve body 131 is connected to the other end of the valve core mounting seat 133 through a flange. The valve core 132 is inserted into the valve body 131, ensuring that the valve core 132 is coaxial with the valve body 131 and has a matching length, so that the valve core 132 can rotate inside the valve body 131, thus constructing a flow control channel for the connecting part and connecting the operating part and the actuating part.
[0036] In this embodiment, the actuating part includes a valve body end positioning ring 137 and a valve inlet 138. The valve body end positioning ring 137 is a cylindrical structure with open ends. The valve body end positioning ring 137 is disposed through the valve core 132 at the other end of the valve body 131. The valve inlet 138 is an open cylindrical structure. One end of the valve inlet 138 is disposed parallel to the valve core rotation lever 136 at the other end of the valve body 131. The open-end cylindrical valve body end positioning ring 137 is taken, fitted into the other end of the valve body 131, and passes through the valve core 132. The inner diameter of the valve body end positioning ring 137 is adapted to the outer diameter of the valve core 132 to achieve end positioning of the valve body 131. Then, the open cylindrical valve inlet 138 is installed at the other end of the valve body 131 through a flange connection, parallel to the valve core rotation lever 136, to ensure that the inlet is connected to the flow channel of the valve body 131. During operation, the polishing fluid flows in through the inlet and is stabilized by the positioning ring to cooperate with the valve body 131 and the valve core 132, thereby achieving flow regulation and output.
[0037] Furthermore, such as Figure 2 As shown, the flow regulating valve 130 uses a cylindrical valve body 131 with openings at both ends as its basic carrier, and a cylindrical valve core 132 of a predetermined length is built into it. A valve core mounting seat 133 with openings at both ends and a valve core adjusting cover 134 are connected to one end of the valve body 131 in sequence. The cylindrical valve core rotating shaft 135 passes through the other end of the valve core adjusting cover 134. Manual adjustment is achieved with the help of a cylindrical valve core rotating lever 136 that is vertically located at the end of the valve core rotating shaft 135. At the same time, the other end of the valve body 131 is fixed by a ring-shaped valve body end positioning ring 137. Finally, a valve inlet 138 with an open cylindrical structure is vertically arranged at the end of the valve body 131. All components work together to form a complete flow regulating valve 130. By rotating the lever, the valve core 132 is rotated, changing the flow matching relationship between the valve core 132 and the valve body 131, so as to achieve precise control of the polishing fluid flow rate.
[0038] In this embodiment, the valve body 131 includes a flange and a connecting cylinder. The flange has a disc-shaped structure, and the connecting cylinder has a cylindrical structure. One end of the connecting cylinder is connected to one end of the flange, and a first circular hole is opened at the top of the other end of the connecting cylinder. The through hole of the connecting cylinder through the polishing liquid tank 120 is located inside the polishing liquid tank 120. The flange has a disc-shaped structure, and the connecting cylinder has a cylindrical structure. One end of the connecting cylinder is fixedly connected to one end of the flange by welding, and a first circular hole is opened at the top of the other end of the connecting cylinder. During installation, the end of the connecting cylinder away from the flange passes through the through hole of the polishing liquid tank 120 until the flange is fitted against the outside of the polishing liquid tank 120 and fixed by the spring pin 310. At this time, the connecting cylinder is located inside the polishing liquid tank 120, laying the foundation for subsequent connection with other components.
[0039] In this embodiment, the valve inlet 138 includes an inlet pipe and an inlet connecting block. The inlet pipe is a cylindrical structure open at both ends, with one end positioned inside the first circular hole of the connecting cylinder. The inlet connecting block is a block-shaped structure open at one end, with one open end connected to the other end of the inlet pipe. An inlet port is provided on the side of the inlet connecting block. The inlet pipe, being a cylindrical structure open at both ends, has one end inserted into the first circular hole of the connecting cylinder and fixed with sealant. The inlet connecting block, being a block-shaped structure open at one end, has one open end welded to the other end of the inlet pipe. An inlet port is provided on the side of the inlet connecting block, which can be connected to the supply pipe 140, allowing the polishing liquid to flow smoothly through the inlet pipe and the inlet connecting block.
[0040] In this embodiment, a feed port threaded cap is also included. The feed port threaded cap is set on the feed port of the polishing liquid tank 120. The feed port threaded cap is directly screwed into the feed port of the polishing liquid tank 120 to seal and prevent leakage, and facilitate liquid replenishment operation.
[0041] In this embodiment, the top of the roller mill 110 is provided with an arc-shaped groove, the curvature of which matches the outer contour curvature of the polishing liquid tank 120, and an anti-slip rubber pad is provided inside the arc-shaped groove. The top of the roller mill 110 is machined with an arc-shaped groove that matches the curvature of the tank body, and an anti-slip rubber pad is attached to stably place the polishing liquid tank 120 and prevent rotation and displacement.
[0042] In this embodiment, the liquid supply pipeline 140 and the flow regulating valve 130 are located on the same side. A groove is formed at the top of the liquid supply pipeline 140, extending through both ends of the pipeline. The liquid supply pipeline 140 is positioned at a certain angle to the horizontal plane on one side of the roller mill 110, and has a predetermined length. By combining the same-side installation with the flow regulating valve 130, the unique groove design, the angle of inclination to the horizontal plane, and the predetermined length, the liquid supply pipeline 140 ensures a tight connection between the two systems. It also utilizes gravity and the groove structure to improve the stability of the polishing fluid delivery, while simultaneously adapting to the overall layout of the device and the required operating distance.
[0043] Furthermore, firstly, the operator unscrews the feed port thread cap 210 and adds an appropriate amount of polishing liquid into the polishing liquid tank 120 through the feed inlet of the upper tank cover 121. After adding, the feed port thread cap 210 is tightened back onto the feed inlet to achieve a seal. Next, the connections of each component are checked to ensure that the flow regulating valve 130, the liquid supply line 140, etc., are securely connected, and that the other end of the liquid supply line 140 extends to the polishing operation area. Then, according to the frequency requirements of the polishing operation, the operator adjusts the rotation speed of the drum 110 using the speed adjustment button on the control panel on the side of the drum 110, setting a suitable rotation speed. Afterwards, the power switch is pressed to start the drive mechanism. The motor runs, and after being reduced in speed and torque by the reducer, it drives the rotating parts of the drum 110 to rotate at the set speed. This causes the polishing liquid tank 120, placed in the arc-shaped groove, to rotate along with the drum 110. The polishing liquid in the tank remains uniform under the action of rotation, and as the rotation speed of the drum 110 changes, the centrifugal force and flow frequency of the polishing liquid change, thereby adjusting the frequency of polishing liquid supply. At this time, the operator can rotate the valve core rotation lever 136 of the flow regulating valve 130 according to the polishing requirements, causing the valve core 132 to rotate within the valve body 131, adjusting the flow area between the valve core 132 and the valve body 131, thereby controlling the outflow rate of the polishing liquid. Under the pressure, gravity, and corresponding frequency generated by the rotation of the polishing fluid tank 120, the polishing fluid enters the inlet pipe through the connecting cylinder, then flows into the supply pipe 140 through the inlet port on the side of the inlet connecting block, and finally is stably delivered to the polishing operation area by the supply pipe 140 at a set frequency, completing the supply of polishing fluid. During the supply process, if the flow rate needs to be adjusted, the valve core rotation lever 136 can be rotated at any time; if the supply frequency needs to be changed, the speed of the roller 110 can be adjusted through the control panel; if the supply needs to be stopped, the power switch is pressed to turn off the drive mechanism, the polishing fluid tank 120 stops rotating, the flow regulating valve 130 is automatically or manually closed, and the supply process ends.
[0044] The polishing slurry supply device of this utility model can provide stable support through a block roller machine and drive the hollow cylindrical polishing slurry tank to rotate. With the synergistic effect of the flow regulating valve that runs through the tank and the grooved inclined rectangular liquid supply pipeline arranged on the same side, it can achieve the effect of stable supply of polishing slurry, precise flow control and strong adaptability.
