Description

Technical Field

[0001] This utility model relates to the field of filling equipment technology, specifically to an automatic filling device for diamond grinding fluid. Background Technology

[0002] Diamond polishing slurry is a core auxiliary material in precision machining fields such as semiconductor wafers, optical glass, and cemented carbide. Diamond polishing slurry can be filled using a filling device.

[0003] If air bubbles are introduced into the diamond polishing slurry during filling, they will create "empty grinding zones" during polishing, resulting in scratches on the workpiece surface. Traditional devices have two major problems with air bubble introduction: first, the filling head uses a "top-down" pouring method, which easily entangles air when the liquid falls from a high position at the bottle opening; second, the inlet of the storage tank is not designed to prevent impact, so when new liquid is added, it directly impacts the surface of the liquid inside the tank, generating a large number of air bubbles, which are difficult to dissipate quickly. In view of this, an automatic filling device for diamond polishing slurry is proposed. Utility Model Content

[0004] The main objective of this invention is to provide an automatic filling device for diamond grinding fluid, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides an automatic filling device for diamond grinding fluid, comprising a frame, a conveyor belt mounted on the frame, a positioning assembly above the conveyor belt, a U-shaped frame fixedly connected to the outer wall of the frame, and a filling mechanism above the conveyor belt, the filling mechanism comprising: A cylinder is fixedly connected to a U-shaped frame. A connecting block is fixedly connected to the output end of the cylinder. A guide rod is fixedly connected to the connecting block. The guide rod passes through the U-shaped frame and is slidably connected to the U-shaped frame. A connecting sleeve, which is fixed to the connecting block; A filling assembly, which is positioned above the conveyor belt.

[0006] Preferably, the filling assembly includes a filling gun, the top of which is provided with a metering pump and a feeding port, and a guide block is fixedly connected to the outer wall of the filling gun, with an insertion hole on the outer wall of the guide block.

[0007] Preferably, an adjustment assembly is provided on the outer wall of the filling gun, a pressure sensor is fixedly installed on the lower side of the adjustment assembly, a sliding ring is slidably connected to the outside of the filling gun, the sliding ring and the pressure sensor are elastically connected by an elastic telescopic rod, and a pressure sleeve is detachably connected to the sliding ring by bolts.

[0008] Preferably, the bottom of the filling gun is provided with a filling port, which is inclined.

[0009] Preferably, the adjusting component includes a collar, which is slidably connected to the outer wall of the filling gun. A groove is provided on the outer wall of the collar, and a slider is slidably connected in the groove. A pin and a pull rod are respectively fixedly connected to both sides of the slider.

[0010] Preferably, the slider and the groove are connected by a reset elastic connection, and the pin matches the socket.

[0011] Preferably, the positioning component includes a positioning plate, a round rod is fixedly connected to the outer wall of the positioning plate, the round rod passes through the sleeve and is slidably connected to the sleeve, a clamping bolt is threaded onto the sleeve, the sleeve is fixedly connected to the mounting plate, and the mounting plate is fixedly connected to the outer wall of the frame.

[0012] This invention provides an automatic filling device for diamond grinding fluid. It has the following advantages: (1) The automatic filling device for diamond grinding fluid solves the problem of air bubbles being easily introduced by traditional filling by optimizing the structure of the filling components. The filling port at the bottom of the filling gun is inclined to prevent the liquid from falling vertically from a height and entraining air. The cylinder drives the connecting block to move the filling gun up and down. During filling, the filling port can be close to the bottom of the container and gradually move upward as the liquid level rises, further reducing the air bubbles generated by the liquid impact. At the same time, the sliding ring and the elastic telescopic rod can fit the container opening during filling to form a local sealed environment, preventing external air from entering and greatly reducing the air bubble content in the grinding fluid. This avoids the formation of "empty grinding zone" due to air bubbles during subsequent grinding, which can cause scratches on the workpiece and ensure the quality of diamond grinding fluid.

[0013] (2) This automatic filling device for diamond grinding fluid, through the design of adjustable components and detachable pressure sleeves, allows the device to adapt to containers of different heights and diameters. By pulling the lever to move the slider, the pin can be pulled out to adjust the height of the collar on the filling gun, thereby changing the position of the pressure sensor to adapt to containers of different heights. The pressure sleeve on the sliding ring is detachable by bolts, and pressure sleeves with different inner diameters can be replaced to fit the mouths of containers of different diameters. It can quickly adapt to the filling needs of various container sizes without replacing the entire filling assembly.

[0014] (3) The diamond grinding fluid automatic filling device uses a positioning component. The positioning plate slides in the sleeve through the round rod. The spacing can be adjusted according to the size of the container and then locked with a clamping bolt. The two sets of positioning plates are symmetrically set, which can limit the container on the conveyor belt from both sides to ensure that the container is always directly below the filling gun.

[0018] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-6This utility model proposes an automatic filling device for diamond grinding fluid, including a frame 1, a conveyor belt 2 on the frame 1, a positioning component 3 above the conveyor belt 2, a U-shaped frame 4 fixedly connected to the outer wall of the frame 1, and a filling mechanism 5 above the conveyor belt 2.

[0021] In an embodiment of this utility model, the filling mechanism 5 includes a cylinder 51, a connecting sleeve 54, and a filling assembly 55. The cylinder 51 is fixedly connected to the U-shaped frame 4, and a connecting block 52 is fixedly connected to the output end of the cylinder 51. A guide rod 53 is fixedly connected to the connecting block 52. The guide rod 53 passes through the U-shaped frame 4 and is slidably connected to the U-shaped frame 4. The connecting sleeve 54 is fixed to the connecting block 52. The filling assembly 55 is set above the conveyor belt 2. With the use of the cylinder 51, the connecting block 52 can be stably raised and lowered under the action of the guide rod 53, thereby ensuring that the filling assembly 55 can be stably raised and lowered, which facilitates the subsequent filling of diamond grinding fluid.

[0022] Furthermore, the filling assembly 55 includes a filling gun 551. A metering pump 552 and a feeding port 553 are located on the top of the filling gun 551. A guide block 554 is fixedly connected to the outer wall of the filling gun 551. An insertion hole 555 is formed on the outer wall of the guide block 554. An adjusting assembly 556 is located on the outer wall of the filling gun 551. A pressure sensor 557 is fixedly installed on the lower side of the adjusting assembly 556. A sliding ring 559 is slidably connected to the outside of the filling gun 551. The sliding ring 559 communicates with the pressure sensor 557. The elastic telescopic rod 558 provides an elastic connection, and the sliding ring 559 is detachably connected to the pressure sleeve 5510 via bolts. The filling gun 551 is driven to descend by the cylinder 51, allowing it to penetrate deep into the container. The pressure sleeve 5510 presses firmly against the container, preventing air from entering. Simultaneously, the metering pump 552 dispenses a precise amount of diamond polishing slurry. The bottom of the filling gun 551 is close to the bottom of the container, gradually moving upwards as the liquid level rises, further reducing air bubbles generated by liquid impact. This prevents scratches on the workpiece caused by "empty grinding zones" formed by air bubbles during subsequent polishing, ensuring the quality of the diamond polishing slurry.

[0023] Furthermore, the bottom of the filling gun 551 is provided with a filling port 5511, which is inclined. Through the inclined filling port 5511, the liquid flows down from the inner wall of the container, which can prevent the liquid from impacting and entraining air.

[0024] Furthermore, the adjustment assembly 556 includes a collar 5561, which is slidably connected to the outer wall of the filling gun 551. A groove is formed on the outer wall of the collar 5561, and a slider 5562 is slidably connected within the groove. A pin 5563 and a pull rod 5564 are fixedly connected to both sides of the slider 5562, respectively. The slider 5562 and the groove are elastically connected via a reset mechanism. The pin 5563 matches the insertion hole 555. By pulling the pull rod 5564, the slider 5562 can be slid, allowing the pin 5563 to be pulled out to adjust the height of the collar 5561 on the filling gun 551, thereby changing the position of the pressure sensor 557 to accommodate containers of different heights. The pressure sleeve 5510 on the sliding ring 559 is removable by bolts, allowing for the replacement of pressure sleeves 5510 with different inner diameters to fit container openings of different sizes. This allows for quick adaptation to the filling needs of various container sizes without replacing the entire filling assembly 55.

[0025] In an embodiment of this utility model, the positioning component 3 includes a positioning plate 31. A round rod 32 is fixedly connected to the outer wall of the positioning plate 31. The round rod 32 passes through the sleeve 33 and is slidably connected to the sleeve 33. A clamping bolt 34 is threadedly connected to the sleeve 33. The sleeve 33 is fixedly connected to the mounting plate 35, and the mounting plate 35 is fixedly connected to the outer wall of the frame 1. By sliding the round rod 32 inside the sleeve 33, the spacing of the positioning plates 31 can be adjusted according to the size of the container, and then locked with the clamping bolt 34. The two sets of positioning plates 31 are symmetrically arranged, which can limit the container on the conveyor belt 2 from both sides to ensure that the container is always directly below the filling gun 551.

[0026] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install, and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here. The standard parts used in this application can all be purchased from the market. The specific connection methods of each part are all connected by conventional means such as riveting and welding that are mature in the prior art. The standard parts are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art.

[0027] In use, first adjust the spacing of the positioning plates 31 by sliding the round rod 32 inside the sleeve 33 according to the container size, and then lock it with the clamping bolt 34. The two sets of positioning plates 31 limit the container on the conveyor belt 2. Then pull the pull rod 5564 to drive the slider 5562 to slide. The pin 5563 can be pulled out to adjust the height of the collar 5561 on the filling gun 551 to adapt to containers of different heights. Then start the cylinder 51. Under the action of the guide rod 53, the connecting block 52 can be raised and lowered stably, thereby ensuring the stable raising and lowering of the filling assembly 55. During filling, the filling gun 551 is driven to descend by the cylinder 51 so that the filling gun 551 can penetrate into the container. The pressure sleeve 5510 can be pressed against the container to prevent air from entering. At the same time, with the use of the metering pump 552, the diamond grinding fluid can be quantitatively added. The bottom of the filling gun 551 is close to the bottom of the container and gradually moves upward as the liquid level rises, further reducing the air bubbles generated by liquid impact.
