Description

Technical Field

[0001] This invention relates to the field of polishing slurry preparation technology, and more specifically to a self-cleaning polishing slurry preparation and supply device. Background Technology

[0002] In machining and precision manufacturing, polishing slurry is a key auxiliary material for improving workpiece machining accuracy and reducing equipment wear. Its formulation quality and supply stability directly impact production efficiency and product quality. Currently, polishing slurry formulation relies heavily on dedicated formulation and supply equipment. This equipment must perform core functions such as raw material mixing, concentration control, and continuous delivery, while also preventing equipment blockage caused by polishing slurry residue and cross-contamination during subsequent formulations. This is to meet the demands of continuous industrial production for polishing slurry that is "ready to use and of stable quality."

[0003] Existing grinding slurry preparation and supply devices suffer from a major problem in practical applications: uneven mixing, delayed viscosity control, and a lack of self-cleaning capabilities, leading to unstable preparation quality. Specifically: First, traditional devices often use unidirectional rotating blades, only achieving planar mixing of raw materials. This easily results in localized material deposition, causing uneven distribution of grinding slurry components and affecting subsequent processing. Second, grinding slurry viscosity is a key quality indicator, and existing devices rely heavily on manual sampling for testing. This results in detection lag and an inability to adjust the raw material ratio in real time based on viscosity changes. This easily leads to substandard grinding slurries with excessively high (thick) or low (thin) viscosity, requiring shutdown and rework, reducing production efficiency. Third, grinding slurry residue easily remains on the internal stirring components and tank walls. Traditional cleaning methods require manual rinsing after shutdown, which is not only time-consuming and labor-intensive but also incomplete. Residual grinding slurry mixes with new raw materials during subsequent preparations, causing a decrease in grinding slurry purity and further exacerbating quality fluctuations, making it difficult to meet the high standards of stable grinding slurry supply required by the precision manufacturing industry.

[0006] Preferably, the stirring mechanism further includes two vertically arranged sliding grooves on the inner wall of the configuration box, with a toothed ring fixedly connected to the inner top wall of the sliding groove, and a gear fixedly connected to the end of the rotating rod away from the mounting cylinder, with the gears on the outer walls of the upper and lower sets of the rotating rod meshing with the two toothed rings respectively.

[0007] Preferably, a rotating ring is fixedly connected to the bottom end of the mounting plate, the bottom end of the fixed cylinder does not contact the inner bottom wall of the configuration box, a limiting rod is fixedly connected to the inner bottom wall of the configuration box, the top end of the limiting rod is fixedly connected to the bottom end of the rotating ring, and a movable plate is sleeved on the outer wall of the reciprocating screw, the movable plate being slidably penetrated by the limiting rod.

[0008] Preferably, the detection mechanism further includes an extension rod fixedly connected to the outer wall of the fixed cylinder, the extension rod intermittently impacting the detection plate.

[0009] Preferably, it also includes a replenishment mechanism, which includes a water inlet and a material replenishment port at the top of the configuration box. A water replenishment pipe is fixedly connected to the top of the configuration box and is connected to the water inlet. A material supply pipe is fixedly connected to the top of the configuration box and is connected to the material replenishment port.

[0010] Preferably, a fixing ring is fixedly connected to the inner circumferential wall of the water supply pipe, a return spring is fixedly connected to the bottom end of the fixing ring, a sealing plate is fixedly connected to the other end of the return spring, the sealing plate is used to block the water inlet, a connecting cylinder is fixedly connected to the bottom end of the sealing plate, an electromagnetic plate is fixedly connected to the inner top of the connecting cylinder, a plastic spring is fixedly connected to the bottom end of the electromagnetic plate, a permanent magnet column is fixedly connected to the bottom end of the plastic spring, a toggle head is fixedly connected to the bottom end of the permanent magnet column, the front end of the toggle head is arc-shaped, and the extension rod slides from the arc-shaped end to the normal end.

[0011] Preferably, a micro motor is fixedly connected to the top of the configuration box, and a baffle plate is fixedly connected to the output end of the micro motor. The baffle plate is used to block the feeding port, and the PLC controller is electrically connected to the electromagnetic plate and the micro motor.

[0012] Preferably, the fixed cylinder has a first water passage chamber inside, which is fixedly connected to the water supply pipe; the mounting cylinder has a second water passage chamber inside, which is connected to the water supply pipe; the rotating rod has a third water passage chamber inside, which is connected to the second water passage chamber; the stirring plate has a fourth water passage chamber inside, which is connected to the third water passage chamber; and a water spray head is fixedly connected to the outer wall of the stirring plate, which is connected to the fourth water passage chamber.

[0013] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. The stirring mechanism of this device is driven by a normal motor to rotate a reciprocating screw, which causes the moving plate, mounting plate, fixed cylinder and other components to move up and down. At the same time, the gear at one end of the rotating rod meshes with the fixed gear ring, so that the rotating rod rotates around the mounting cylinder when it moves up and down, which drives the stirring plate to move up and down and rotate, thus realizing three-dimensional stirring. This solves the limitation of planar stirring caused by the traditional single-direction rotating stirring blade, avoids local material deposition, and makes the composition of the grinding liquid more evenly distributed.

[0014] 2. In the detection mechanism, the extension rod, which moves up and down with the fixed cylinder, intermittently impacts the detection plate, which is elastically hinged and has a built-in pressure sensor. The pressure sensor transmits the detected pressure value to the PLC controller. When the viscosity is abnormal, the PLC controller can quickly control the replenishment mechanism to add water or material, eliminating the need for manual sampling and testing. This enables real-time monitoring and adjustment of the grinding fluid viscosity, avoiding unqualified grinding fluid caused by lag, reducing downtime and rework, and improving production efficiency.

[0015] 3. The fixed cylinder, water supply pipe, mounting cylinder, rotating rod, and stirring plate of this device are equipped with interconnected water passage chambers. During stirring, the grinding liquid or cleaning water can be sprayed out from the spray head through these water passage chambers to rinse the inner wall of the mixing tank and each stirring component in real time. No manual cleaning is required after machine shutdown, saving time and labor while ensuring thorough cleaning. This prevents residual grinding liquid from affecting the next batch, guarantees the purity of the grinding liquid, and reduces fluctuations in the quality of the mixture.

[0030] The working principle of this invention is as follows: In the actual production process of the self-cleaning grinding fluid preparation and supply device, the stirring stage is started first to lay the foundation for the uniform mixing of the grinding fluid. In the initial stage, the main raw materials and water of the grinding fluid are initially added through the replenishment mechanism 7: the sealing plate 77 in the water replenishment pipe 73, under the control of the PLC controller, attracts the permanent magnet column 711 by the electromagnetic plate 79, which drives the sealing plate 77 to move down and open the water inlet 71, and water flows into the preparation box 1; at the same time, the micro motor 713 drives the blocking plate 714 to rotate, opening the feeding port 72, and the main raw materials enter the preparation box 1 through the feeding pipe 74. After the initial raw material addition is completed, all components are reset and sealed. Then the stirring mechanism 5 is started. The normal motor 51 drives the reciprocating screw 52 to rotate. Because the moving plate 514 is restricted from rotating by the limit rod 513, the rotation of the reciprocating screw 52 is converted into the moving plate 514 moving up and down along the limit rod 513, which in turn drives the mounting plate 53, the fixed cylinder 54, the water supply pipe 55 and the mounting cylinder 56 to move up and down synchronously. During this process, the gear 511 at one end of the rotating rod 57 on the outer periphery of the mounting cylinder 56 is always engaged with the toothed ring 510 in the sliding groove 59 on the inner wall of the configuration box 1. The toothed ring 510 is fixed, so that the rotating rod 57 rotates around the mounting cylinder 56 while moving up and down with the mounting cylinder 56. The stirring plate 58 on the outer wall of the rotating rod 57 rotates accordingly, which fully stirs the raw materials in the configuration box 1 and officially starts the stirring process. After the stirring process is started, the detection mechanism 6 simultaneously enters the working state, continuously detecting the viscosity of the grinding slurry during the stirring process to monitor the quality of the grinding slurry preparation in real time. In the detection mechanism 6, a detection plate 62, elastically hinged to the mounting bracket 61 on the top wall of the preparation box 1, has a pressure sensor embedded inside that is electrically connected to the PLC controller. The extension rod 515, which moves up and down with the fixed cylinder 54, intermittently impacts the detection plate 62 during its movement. When the grinding slurry is in a stirring and mixing state, if the viscosity is normal, the impact force generated by the extension rod 515 striking the detection plate 62 will cause the detection plate 62 to rotate by a preset amplitude. If the pressure value detected by the pressure sensor is within the normal range, the signal is transmitted to the PLC controller, which determines that no adjustment is needed, and the stirring mechanism continues to maintain normal stirring. If the grinding fluid viscosity is found to be too high (too thick), the resistance of the grinding fluid to the detection plate 62 will increase. After the extension rod 515 impacts, the rotation amplitude of the detection plate 62 will decrease. The pressure value detected by the pressure sensor will exceed the upper limit of the normal range. The signal will be transmitted to the PLC controller, and the controller will immediately start the water replenishment process: control the electromagnetic plate 79 in the water replenishment pipe 73 to be energized, attract the permanent magnet column 711 to drive the sealing plate 77 to move down and open the water inlet 71. Water will flow into the configuration box 1 through the water replenishment pipe 73. At the same time, the stirring mechanism will continue to stir, so that the newly added water and the original grinding fluid will be quickly mixed until the pressure sensor detects that the pressure value has returned to the normal range. The PLC controller will control the sealing plate 77 to reset and stop the water replenishment. If the grinding slurry viscosity is found to be too low (too thin), the resistance of the grinding slurry to the detection plate 62 will decrease. After the extension rod 515 impacts, the rotation amplitude of the detection plate 62 will increase. The pressure value detected by the pressure sensor will be lower than the lower limit of the normal range. After receiving the signal, the PLC controller will start the feeding process: control the micro motor 713 to rotate, drive the baffle plate 714 to open the feeding port 72, and the main raw materials will enter the configuration box 1 through the feeding pipe 74. The stirring mechanism will continuously stir to achieve uniform mixing of the raw materials. When the pressure sensor detects that the pressure value has returned to normal, the controller will control the baffle plate 714 to reset and stop feeding. Throughout the entire process of stirring, testing, and adjustment, the self-cleaning function of the device operates synchronously to prevent grinding fluid residue from affecting subsequent production. The first water passage chamber inside the fixed cylinder 54 is connected to the water supply pipe 55. The second water passage chamber of the mounting cylinder 56, the third water passage chamber of the rotating rod 57, and the fourth water passage chamber of the stirring plate 58 are sequentially connected, and the water spray head 8 on the outer wall of the stirring plate 58 is connected to the fourth water passage chamber. During stirring, the grinding fluid in the preparation tank 1 enters the first water passage chamber, passes through the water supply pipe 55, the second water passage chamber, the third water passage chamber, and the fourth water passage chamber, and is then sprayed out from the water spray head 8 to rinse the inner wall of the preparation tank 1, the stirring plate 58, the rotating rod 57, and other components in real time. If more thorough cleaning is required, clean water can be introduced into the preparation tank 1 through the water supply pipe 73, and the above water flow process can be repeated to achieve comprehensive self-cleaning of the device's interior, without interrupting stirring and testing during the cleaning process. When the grinding fluid that has been stirred, tested and adjusted to meet the requirements needs to be supplied, while the stirring mechanism keeps stirring at a low speed to prevent the grinding fluid from settling, the water pump 2 at the bottom of the preparation tank 1 is started. The water pump 2 draws the qualified grinding fluid from the bottom wall of the preparation tank 1 through the water pipe 3, and then transports it to the place where it is used in production through the drain pipe 4, so as to continuously supply grinding fluid for production. If the amount of grinding fluid in the preparation tank 1 decreases, the initial raw material feeding, stirring, testing and adjustment process can be repeated to ensure a continuous and stable supply of grinding fluid and complete the cycle of the entire production process. The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
