Description

Technical Field

[0001] This utility model relates to the field of sapphire polishing technology, specifically to a sapphire edge polishing device. Background Technology

[0002] In the field of optics, sapphire is widely used to manufacture precision optical components such as optical windows and lenses due to its high hardness, high light transmittance and good thermal stability. In the field of electronics, sapphire plays a key role in chip performance as a semiconductor substrate material.

[0003] In the field of optical applications, the smoothness of the sapphire edge has a significant impact on the propagation of light. Rough edges can cause light scattering, reducing the light transmittance and image clarity of the optical system. Polishing equipment can polish the sapphire edge to a smooth and flat surface, reducing light scattering, improving optical performance, and at the same time avoiding stress concentration.

[0004] Current sapphire polishing devices generally have a structure similar to that described in patent application CN202420014541.9, which discloses a sapphire lens edge polishing device. This device includes a base, a polishing box fixedly connected to the top of the base, a transparent window at the front of the polishing box, a vacuum cleaner on the side of the polishing box, an operating port on the side of the polishing box, and a motor A fixedly connected to the side of the polishing box. Motor A is driven by a bidirectional threaded rod via its output shaft. A sliding plate is slidably connected inside the polishing box, and the sliding plate is threadedly connected to the bidirectional threaded rod. This application incorporates a water spray dust suppression mechanism. When motor B is activated, it drives a rotating shaft. The rotating shaft drives the polishing disc to polish, and it also drives a pressure chamber to draw water from a water tank through a telescopic hose, spraying water onto the polishing disc through a water spray pipe. This reduces dust generated during polishing and prevents dust from obstructing the operator's vision. However, this utility model mainly relies on a single grinding disc for grinding operations, resulting in low grinding efficiency, insufficient smooth transitions between different processes, the need for manual adjustments, and a long grinding cycle, which cannot meet the needs of large-scale production.

[0005] Therefore, this invention proposes a sapphire edge polishing device to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to provide a sapphire edge polishing device to solve the problem that the conversion between different processes in the prior art requires manual adjustment, which cannot meet the needs of large-scale production.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A sapphire edge polishing device includes a polishing worktable and a polishing assembly. The polishing assembly is disposed on one side of the polishing worktable, and a fixing fixture is connected to the polishing worktable. The polishing assembly includes a base, a coarse polishing device, a fine polishing device, and a polishing device. The coarse polishing device, fine polishing device, and polishing device are all slidably connected to the base. The coarse polishing device includes a first slide block, on which a first slide table is slidably connected. The sliding direction of the first slide block and the first slide table is perpendicular. A coarse polishing machine is connected to the first slide table. A first coolant spraying device is connected above the machine; the fine grinding device includes a second slide block, on which a second slide table is slidably connected, the sliding direction of the second slide block and the second slide table is perpendicular, a fine grinding machine is connected to the second slide table, and a second coolant spraying device is connected above the fine grinding machine; the polishing device includes a third slide block, on which a third slide table is slidably connected, the sliding direction of the third slide block and the third slide table is perpendicular, a polishing machine is connected to the third slide table, and a polishing liquid spraying device is connected above the polishing machine.

[0009] By adopting the above technical solutions, the coarse grinding device, fine grinding device and polishing device can work independently, thereby enabling different stages of sapphire grinding, realizing automatic process conversion, shortening the grinding cycle and improving grinding efficiency.

[0010] Furthermore, a dust cover is connected to the grinding worktable, and the dust cover is positioned above the fixing fixture.

[0011] By adopting the above technical solution, the spread of dust generated during the polishing process can be blocked, dust pollution can be avoided, and the cleanliness of the work area can be maintained.

[0012] Furthermore, the fixing fixture includes a first fixture and a second fixture, which are arranged opposite to each other. The first fixture includes a driving device, a first turntable, and a first suction cup. The driving device is fixedly connected to the grinding worktable, the first turntable is connected to the drive shaft of the driving device, and the first suction cup is connected to the first turntable. The second fixture includes a connecting frame, a second turntable, and a second suction cup. A sliding frame is slidably connected to the connecting frame, and a driving cylinder drives the sliding frame to slide. The driving cylinder is fixedly connected to the connecting frame. The second turntable is rotatably connected to the sliding frame, and the second suction cup is connected to the second turntable.

[0013] By adopting the above technical solution, the first suction cup on the first turntable adsorbs and fixes the sapphire, and the second clamp pushes the sliding frame through the drive cylinder, thereby driving the second turntable and the second suction cup to move. The second suction cup further adsorbs the sapphire. The clamping force can be flexibly adjusted according to the size of the sapphire to ensure the stability of the sapphire during the polishing process and avoid shaking that affects the polishing accuracy.

[0014] Furthermore, the top surface of the grinding workbench is inclined, and a receiving box is provided on one side of the grinding workbench, which is slidably connected to the grinding workbench.

[0015] By adopting the above technical solution, the debris and coolant generated during grinding can flow along the inclined top surface of the grinding workbench to the receiving box under the action of gravity. The receiving box is slidably connected to the grinding workbench, which facilitates the centralized collection and treatment of waste materials and keeps the work area clean.

[0016] Furthermore, the grinding workbench is evenly provided with multiple water outlet holes corresponding to the opening of the receiving box. Each water outlet hole is connected to a water suction pipe, and the ends of the water suction pipes away from the water outlet holes are all connected to a water pump.

[0017] By adopting the above technical solution, the water pump can promptly extract the coolant from the receiving box, preventing the coolant from accumulating in the receiving box, ensuring the continuity of grinding work, and improving work efficiency.

[0018] Furthermore, each of the water outlet holes is connected to a filter screen.

[0019] By adopting the above technical solution, larger debris in the coolant can be intercepted, preventing debris from entering the suction pipe and water pump and causing blockage.

[0020] Furthermore, the ends of the first coolant spraying device, the second coolant spraying device, and the polishing liquid spraying device are all connected to atomizing nozzles.

[0021] By adopting the above technical solution, the contact area between the liquid and the polishing part can be increased, thereby playing a role in cooling, lubrication and auxiliary polishing, improving the polishing quality and avoiding damage to the sapphire during the polishing process.

[0022] In summary, compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] This invention's coarse grinding device, fine grinding device, and polishing device can operate independently, enabling different stages of sapphire grinding. This achieves automated process switching, shortens the grinding cycle, and improves grinding efficiency. Furthermore, the coarse grinding device, fine grinding device, polishing device, and fixing fixture can be flexibly adjusted to meet the grinding needs of sapphires of different sizes in large-scale production, ensuring grinding quality.
