TECHNICAL FIELD
[0001] The utility model relates to a kind of sapphire grinding liquid filtering equipment. BACKGROUND
[0002] Sapphire grinding liquid is used for grinding and thinning on sapphire substrate. Sapphire grinding liquid is composed of high-quality polycrystalline diamond powder, composite dispersant and dispersion medium. Sapphire grinding liquid utilizes the characteristics of polycrystalline diamond to maintain high cutting efficiency during grinding and polishing while preventing scratches on workpieces.
[0003] Chinese patent discloses a processing device for ultrasonic grinding of sapphire lenses (authorized publication number CN221364368U). The processing device for ultrasonic grinding of sapphire lenses can collect the generated grinding liquid and filter the internal waste chips during use through the design of the collection box, liquid inlet, filter screen, collection port, fixed pipeline, driving rod, fixed plate, transmission belt, driven shaft and cam.
[0004] According to the above reference case, the device guides the waste chips to the top of the filter screen for filtration through the collection port. The filtration intensity of the local filter screen directly below the collection port is greater than that of the rest of the filter screen, which increases the wear and blockage rate of the filter screen at this location, thereby reducing the service life of the filter screen.
[0005] Therefore, the utility model designs a kind of sapphire grinding liquid filtering equipment to solve the above problems. SUMMARY
[0006] To overcome the above-mentioned shortcomings of the prior art, the utility model provides a sapphire grinding liquid filtering equipment.
[0007] To achieve the above purpose, the utility model realizes the following technical solutions:
[0008] A sapphire grinding liquid filtering equipment includes a collection box and a filtering mechanism. The top of the collection box is provided with an inlet, and the side end of the collection box is provided with a treatment cavity communicating with the inlet. The inside of the collection box is provided with a collection cavity communicating with the treatment cavity.
[0009] Further, the filtering mechanism comprises a drawer inserted into the processing cavity, a circular cavity is formed in the top of the drawer, the feeding port is arranged above the circular cavity, a mounting frame is fixedly connected to the inside of the circular cavity, a servo motor is fixedly connected to the inner side of the mounting frame, a circular frame is slidably connected to the surface of the output shaft of the servo motor, and a filter screen is embeddedly installed on the inner bottom wall of the circular frame. The servo motor can continuously replace the local filter screen below the feeding port through the circular frame, so as to avoid that the same position of the filter screen is impacted for a long time, reduce the impact force and excessive burden of the filter screen, and prolong the service life of the filter screen. Meanwhile, the circular frame can actively guide the grinding liquid to the surrounding through rotation, which can increase the contact area of the grinding liquid and the filter screen, and improve the filtering efficiency of the filter screen on the waste in the grinding liquid.
[0010] Further, the inner bottom wall of the circular frame is in the shape of a cone, and the upper surface of the filter screen is flush with the inner bottom wall of the circular frame, which can increase the flowability of the grinding liquid on the surface of the filter screen, and further increase the contact area of the grinding liquid and the filter screen.
[0011] Further, the bottom of the circular frame is fixedly connected with a protective sleeve slidably connected with the output shaft of the servo motor, the protective sleeve is sleeved on the surface of the mounting frame, and the servo motor is arranged between the mounting frame and the protective sleeve, which can prevent the grinding liquid from penetrating into the servo motor, so as to ensure that the servo motor can stably operate.
[0012] Further, the top of the mounting frame is provided with an annular slope, the inner top wall of the protective sleeve is provided with a square groove, and the filtering mechanism further comprises a guide assembly, the guide assembly comprises a square block and a guide rod, the square block is slidably connected to the inside of the square groove, the bottom of the square block is fixedly connected with the end of the output shaft of the servo motor, and the guide rod is fixedly connected to the inner top wall of the protective sleeve. The bottom of the guide rod is in contact with the lowest part of the annular slope, and the guide assembly cooperates with the square groove and the annular slope to continuously lift and lower the grinding liquid, which can continuously change the kinetic energy and potential energy of the falling grinding liquid, increase the rate of the grinding liquid passing through the filter screen, and further improve the filtering efficiency of the waste in the grinding liquid.
[0013] Further, the straight line length of the annular slope from the axis of the servo motor is the same as the straight line length of the guide rod from the axis of the servo motor; and the slidable height of the square block in the square groove is greater than the height difference between the lowest part and the highest part of the annular slope, which can ensure that the guide assembly can stably operate.
[0014] Further, the bottom of the guide rod is embeddedly installed with a ball, and the lower surface of the ball is in contact with the annular slope, which can reduce the sliding resistance of the guide rod on the annular slope, so that the circular frame can be lifted and lowered more smoothly.
[0015] Beneficial effects:
[0016] 1. The servo motor, through the circular frame, can not only continuously replace the filter screen located below the feed inlet, preventing the same position of the filter screen from being impacted for a long time, thus reducing the impact force and excessive load on the filter screen and extending its service life, but the circular frame can also actively guide the grinding liquid to all sides by rotating. This increases the contact area between the grinding liquid and the filter screen, thereby improving the filter screen's filtration efficiency for waste debris in the grinding liquid.
[0017] 2. The guide component, together with the square groove and the annular ramp, can drive the grinding fluid to rise and fall continuously. This can continuously change the kinetic energy and potential energy of the grinding fluid as it falls, increasing the rate at which the grinding fluid passes through the filter screen and further improving the filtration efficiency of waste in the grinding fluid.
