Description

Technical Field

[0001] This invention relates to the field of quartz boat polishing technology, and more particularly to a machine tool for surface smoothing of quartz boats. Background Technology

[0002] Quartz boat surface smoothing machine tools use grinding, polishing and other processes to control the surface roughness of quartz boats to an extremely low level, while ensuring dimensional and positional tolerances such as flatness and parallelism, to meet the stringent requirements of subsequent precision production for the cleanliness and flatness of the carrier.

[0003] In Chinese Patent Publication No. CN120326485B, an invention discloses a quartz boat polishing device, belonging to the field of automatic quartz polishing technology. It includes a hanger, a crossbar fixedly mounted on the upper surface of the hanger, a cross-sliding mechanism slidably mounted on the outer surface of the crossbar, and a polishing mechanism fixedly mounted on the lower surface of the cross-sliding mechanism. This allows the cross-sliding mechanism to push the polishing mechanism onto the outer surface of the quartz boat, enabling the polishing mechanism to perform lateral pushing polishing of the outer surface of the quartz boat. The application's polishing mechanism design allows it to automatically adapt to the protrusions and depressions on the outer surface of the quartz boat during polishing. This feature makes the polishing process more precise, ensuring that the polishing mechanism maintains appropriate polishing pressure and contact with the quartz boat surface regardless of the complexity of the quartz boat's surface shape. This effectively avoids over-polishing or under-polishing, greatly improving polishing accuracy and the quality of the finished quartz boat.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: When using existing quartz boat surface smoothing machines, the surface of the quartz boat is smoothed by grinding. However, during the grinding process, dirt may be present on the surface of the quartz boat. This dirt may scratch the quartz boat during the grinding process, affecting the quality of the quartz boat. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the surface of the quartz boat is dirty, which leads to scratches on the quartz boat during the polishing process. To address this, we propose a quartz boat surface smoothing machine.

[0016] The technical effects and advantages of this invention are as follows: In this invention, a smoothing grinding disc with a guide groove is provided. During the grinding process, the dirt on the surface of the quartz boat is transferred to the collection groove through the guide groove, preventing the dirt from scratching the quartz boat. During the grinding process, the first electric telescopic rod periodically lifts the smoothing grinding disc.

[0020] According to one embodiment of the present invention, Figures 1 to 8 As shown.

[0021] Existing quartz boat surface smoothing machines smooth the surface of quartz boats through grinding. However, during the grinding process, the surface of the quartz boat will have quartz micro-shavings, abrasive residues, and trace amounts of dust from the environment. If these contaminants are not removed in time, they will form a contact surface with the grinding head and the quartz boat surface during the grinding process, causing irreversible scratches to the quartz boat. From the perspective of the quartz boat's structural quality, scratches will directly damage its high-strength and high-stability material properties. The core material of the quartz boat is high-purity quartz glass, but it is brittle. Extremely strong surface scratches, seemingly just grooves, actually create cracks within the quartz glass. These micro-cracks worsen during subsequent use, affecting the quality of the quartz boat. Furthermore, the heat during polishing concentrates in the polished area while the unpolished area remains cool, resulting in a severe temperature gradient within the boat. This generates thermal stress far exceeding the quartz glass's tolerance limits, potentially causing surface cracks that also impact its quality. To address this issue, this invention incorporates the following design in a quartz boat surface smoothing machine: The quartz boat surface smoothing machine tool includes: a machine body 1. This quartz boat processing machine tool is a specialized automated equipment for customized processing, surface treatment, and quality optimization of quartz boats. It has stringent requirements for high precision, high cleanliness, and defect-free quartz boats. It is not a single-function machine tool, but a composite processing system integrating multiple stages such as structural forming, surface finishing, cleanliness control, and defect prevention. Essentially, it transforms quartz boat blanks into finished parts that meet downstream process standards through precise mechanical movements and environmental control. A quartz boat fixing area 2 is fixedly connected to the top of the machine body 1. The quartz boat fixing area 2 refers to the structure that fixes the quartz boat during the grinding process, ensuring its stability. A smoothing grinding disc 3 is installed at the top of the boat fixing area 2. The smoothing grinding disc 3 is a structure used in the quartz boat processing machine to smooth the surface of the quartz boat. The smoothing grinding disc 3 has a guide groove 4 inside and a concentration groove 5 on its side. An annular support 6 is slidably connected inside the concentration groove 5. A device spring 7 is fixedly connected to the top of the annular support 6. A telescopic outer shell 8 is provided on the side of the device spring 7. A telescopic inner rod 9 is slidably connected inside the telescopic outer shell 8. A support block 10 is fixedly connected to the bottom of the annular support 6. An air guide hole 11 is opened inside the support block 10. A grinding machine 12 is fixedly connected to the top of the smoothing grinding disc 3. The grinding machine 12 is a device that uses an abrasive to physically process the surface of the workpiece. The core function of this grinding machine 12 is to remove defects, burrs, oxide layers, stains, etc. from the surface of the workpiece through relative friction between the grinding wheel and the workpiece surface, thereby shaping and polishing the surface. A first fixed plate 13 is fixedly connected to the top of the grinding machine 12. A device shaft 14 is rotatably connected to the side of the first fixed plate 13. A device gear 15 is fixedly connected to one end of the device shaft 14. A device rack 16 meshes with the side of the device gear 15. A second fixed plate 17 is fixedly connected to the top of the device rack 16. A device fan 18 is fixedly connected to the outer wall of the device shaft 14. A first electric telescopic rod 19 is fixedly connected to the bottom of the second fixed plate 17. A second electric telescopic rod 20 is fixedly connected to the top of the second fixed plate 17. It is a mechanical actuator that converts electrical energy into linear reciprocating motion through motor drive. Its core function is to realize linear movements of extension or retraction. It can precisely control the stroke, speed and force of extension and retraction without relying on human power or traditional power sources such as hydraulics or pneumatics. The top of the No. 2 electric telescopic rod 20 is fixedly connected to the drive mechanism 21. The drive mechanism 21 is the core component collection in the mechanical system responsible for providing the power transmission path and converting the motion form. Its essence is to connect the power source and the actuator. Through a specific mechanical structure, it converts the energy of the power source into the motion form required by the actuator and realizes the control of speed, torque and direction, and finally drives the load to complete the expected action. The drive mechanism 21 is internally slidably connected to the device slide rail 22.

[0022] The guide channel 4 is arc-shaped, and ten guide channels 4 are set at equal angles to the vertical central axis of the smoothing grinding disc 3. The device spring 7 is fixedly connected to the smoothing grinding disc 3, and five device springs 7 are set at equal angles to the vertical central axis of the annular bracket 6. The telescopic outer shell 8 is fixedly connected to the annular bracket 6, and the telescopic inner rod 9 is fixedly connected to the smoothing grinding disc 3. The air guide hole 11 is located at the center of the support block 10, and ten support blocks 10 are set at equal angles to the vertical central axis of the annular bracket 6. A pair of device gears 15 are symmetrically arranged about the vertical central axis of the device shaft 14, and a pair of device shafts 14 are symmetrically arranged about the vertical central axis of the first fixed plate 13. The device fan 18 is positioned about the vertical central axis of the first fixed plate 13. A pair of devices are symmetrically arranged along the central axis. The device fan 18 serves to blow air and is used to clean and dissipate heat for the core process of the equipment by precisely controlling the airflow pressure, direction, volume and timing, so as to ensure process accuracy and product quality. The first electric telescopic rod 19 is fixedly connected to the first fixed plate 13. The first electric telescopic rod 19 is used to control the movement of the first fixed plate 13. The drive mechanism 21 slides on the device slide rail 22. A pair of devices slide rails 22 are symmetrically arranged about the horizontal central axis of the drive mechanism 21. The device slide rail 22 is fixedly connected to the side of the device slide rail 22. The controller 23 is the intelligent hub that coordinates the work of all core components of the equipment and ensures the grinding accuracy and the quality of the quartz boat. The controller 23 is fixedly connected to the machine tool body 1.

[0023] When the machine tool body 1 is in use, the quartz boat is fixed in the quartz boat fixing area 2, and the device is controlled by the controller 23. At this time, the drive mechanism 21 slides on the device slide rail 22 until the smoothing grinding disc 3 is in a suitable horizontal position. Then, the second electric telescopic rod 20 is activated to adjust the vertical position of the smoothing grinding disc 3 until it contacts the surface of the quartz boat. Before grinding begins, the first electric telescopic rod 19 starts working and retracts, raising the smoothing grinding disc 3. As the first fixing plate 13 rises, the device gear 15 moves on the surface of the device rack 16. At this time, the device shaft 14 and the device gear 15 begin to rotate, causing the device fan 18 to tilt. The device fan 18 blows air to clean the grinding area. After cleaning, the first electric telescopic rod 19 returns to its initial position, and the grinder 12 is turned on. At this time, the smoothing grinding disc 3 grinds the surface of the quartz boat. During the rotation of disc 3, the dirt on the bottom of the smoothing grinding disc 3 is transferred to the concentrating groove 5 through the guide groove 4. The support block 10 divides the space in the concentrating groove 5. Under the action of the concentrating groove 5, the dirt inside and outside the smoothing grinding disc 3 is isolated. The dirt inside is concentrated and collected, while the dirt outside is blocked. After timed grinding, the first electric telescopic rod 19 begins to retract, lifting the smoothing grinding disc 3. At this time, under the action of gravity, the annular support 6 begins to slide down. The annular support 6 scrapes the inner wall of the concentrating groove 5 to discharge the dirt. The device spring 7 provides elastic support for the annular support 6 and controls the downward movement distance of the annular support 6. The telescopic outer shell 8 and the telescopic inner rod 9 play a limiting role to ensure the accurate position of the annular support 6. At this time, the device fan 18 starts to blow air to clean the ground area. At the same time, some air changes its trajectory through the air guide hole 11 to clean the bottom of the smoothing grinding disc 3.

[0024] A smoothing grinding disc 3 with guide grooves 4 is provided. The grooves 4 extend outward in an equidistant spiral pattern from the center of the grinding disc. Quartz micro-shavings, abrasive residues, and trace amounts of dust from the environment, generated during grinding, are guided by centrifugal force and the guide grooves 4 to slide directionally towards the edge of the grinding disc along the spiral pattern. Ultimately, all of these contaminants converge into the collection grooves 5 on the outer ring of the smoothing grinding disc 3, thus eliminating the risk of scratches caused by contaminants trapped between the grinding disc and the quartz boat. During the polishing process, dirt on the surface of the quartz boat is transferred to the collection tank 5 through the guide channel 4 to prevent the dirt from scratching the quartz boat. During the polishing process, the first electric telescopic rod 19 periodically lifts the smoothing grinding disc 3. When the smoothing grinding disc 3 is lifted, the annular support 6 descends, scraping off the dirt in the collection tank 5. At the same time, the device fan 18 rotates to the working position and blows air onto the polished area to clean the accumulated dirt. When the device fan 18 blows air, some air enters... The airflow into the guide hole 11 cleans the surface of the smoothing grinding disc 3. The timed operation of the device fan 18 not only cleans but also dissipates heat, preventing the high heat generated during grinding from causing the quartz boat to break. The core material of the quartz boat is high-purity quartz glass, which is resistant to high temperatures but has extremely poor thermal shock toughness. During grinding, the high-speed friction between the smoothing grinding disc 3 and the surface of the quartz boat generates a large amount of local heat. If the heat cannot be dissipated in time, a severe temperature gradient will form inside the quartz boat, leading to micro-cracks or even breakage due to thermal stress concentration. After the device fan 18 is started, the high-pressure airflow will quickly remove the heat from the grinding area, reducing the surface temperature of the smoothing grinding disc 3 and effectively mitigating the impact of thermal stress on the quartz boat, thus reducing the breakage rate of the quartz boat due to high temperature. At the same time, the airflow can also assist in the cooling of the motor, electric telescopic rod, and other drive components of the smoothing grinding disc 3, preventing long-term high temperature from causing component aging and extending the service life of the equipment.

[0025] The smoothing grinding disc 3 with guide groove 4 can direct quartz chips, abrasive residues, and other contaminants generated during grinding into the collection tank 5, preventing contaminants from getting trapped between the grinding disc and the quartz boat and forming grinding impurities. This prevents scratches, pits, and other damage to the surface of the quartz boat from the source. During the grinding process, the high-speed friction between the grinding disc and the quartz boat generates localized high temperatures. High-purity quartz glass has poor thermal shock toughness and is prone to cracking due to thermal stress. The timed cooling function of the fan 18 can quickly lower the temperature of the grinding area, preventing micro-cracks and breakage of the quartz boat caused by concentrated thermal stress. The spiral radial structure of 4 uses centrifugal force to precisely guide the stains into the collection tank 5, preventing the stains from scattering irregularly on the surface of the grinding disc or quartz boat. The ring bracket 6 fits tightly against the inner wall of the collection tank 5, thoroughly scraping away the accumulated stains in the tank and preventing the stains from hardening and clumping due to long-term adhesion. The high-pressure airflow of the device fan 18 can not only clean the residual debris in the grinding area, but also clean the surface of the smoothing grinding disc 3 through the air guide hole 11. By removing the dirt, the dirt is prevented from scratching the quartz boat, effectively ensuring the efficiency of the quartz boat smoothing process and improving the quality of the product.
