[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] As attached Figures 1 to 4The device is an automated optical crystal glass surface finishing device, comprising a base 1, a buffer ring 4, and a finishing assembly 7. The buffer ring 4 is sleeved on the outer surface of a rotating roller 3. A first motor 5 is disposed behind one set of support plates 2. A second gantry 8 is disposed on the upper left end of the support plates 2, with a polishing wheel 13 disposed at the center of the second gantry 8. A first gantry 6 is disposed on the right side of the upper end of the support plates 2, with the finishing assembly 7 disposed at the center of the first gantry 6.

[0025] The finishing component 7 includes a spray water pipe 701, which is arranged at the center of the inner cavity of the first gantry 6. A spray head 702 is provided at the lower end of the spray water pipe 701, and four groups of spray heads 702 are provided. A connecting hose 703 is provided on the right side of the upper end of the spray water pipe 701. A water tank 704 is provided in the central lake of the upper end of the first gantry 6, and a nano-suspension 705 is provided in the inner cavity of the water tank 704, and a water pump 706 is provided on the right side of the water tank 704.

[0026] Among them: when polishing the glass surface, the optical glass is supported by several groups of buffer rings 4. The buffer rings 4 have good elasticity and buffering performance, which can effectively absorb the impact force generated when the polishing wheel 13 contacts the optical glass for polishing. Through the compression and recovery of the buffer rings 4, the impact force can be dispersed at the moment of contact, reducing the direct impact on the optical glass and avoiding potential cracks or damage. The first motor 5 can drive the four groups of rotating rollers 3 to rotate, thereby driving the buffer rings 4 to rotate and slowly transporting the glass forward. When the polishing wheel 13 polishes the glass, the material of the nanoparticles is silicon dioxide. By mixing the nanoparticles with an organic solvent The nano-suspension 705 is mixed to form a uniform nano-suspension 705, and the nano-suspension 705 is stored in a water tank 704. The nano-suspension 705 in the water tank 704 is then extracted by a water pump 706 and sent to the spray water pipe 701 through a connecting hose 703. The nano-suspension 705 is then atomized by a spray head 702 and sprayed evenly onto the glass surface. The size of the nano-particles is between 1 and 100 nanometers. Then, through combination with the polishing wheel 13, the nano-particles of the nano-suspension 705 can fill the tiny pits and scratches on the surface of the optical glass during the polishing process and form a thin protective film, which significantly improves the smoothness of the surface.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working methods. Figures 1 to 4 As shown, see the following description for details:

[0029] As a preferred embodiment, support plates 2 are provided at the front and rear ends of the base 1, and rotating rollers 3 are provided at the upper ends of the opposite surfaces of the two groups of support plates 2. There are four groups of rotating rollers 3 and the first motor 5, and one end of each group of rotating rollers 3 protruding from one group of support plates 2 is connected to the output end of the first motor 5; furthermore, the installation of the two groups of support plates 2 can help to evenly distribute the load borne by the rotating rollers 3, and the rotating rollers 3 can rotate smoothly under the support plates 2.

[0030] As a preferred embodiment, electric push rods 9 are provided on both sides of the upper end of the second gantry 8, and the output ends of the two groups of electric push rods 9 are provided with mounting plates 11, a second motor 10 is provided at the center of the mounting plate 11, and a transmission shaft 12 is provided at the center of the lower end of the mounting plate 11, and a polishing wheel 13 is installed at the lower end of the transmission shaft 12; further, the electric push rods 9 drive the mounting plate 11 to perform lifting and lowering movements by adjusting the extension and retraction.

[0031] As a preferred embodiment, the end of the connecting hose 703 away from the spray water pipe 701 is connected to the output end of the water pump 706, and the water tank 704 is connected to the input end of the water pump 706; further, the connecting hose 703 can be connected to the output end of the water pump 706, so that the water pump 706 outputs liquid through the connecting hose 703, and the water pump 706 draws out the nanosuspension 705 in the water tank 704 through the output end.

[0032] As a preferred embodiment, several groups of buffer rings 4 are provided, and the positions between the several groups of buffer rings 4 are arranged at equal intervals, and the buffer rings 4 are made of rubber; furthermore, the rubber material of the buffer rings 4 has good elasticity and buffering properties, which can effectively absorb and reduce external impact and vibration, and protect the optical glass during polishing. The design of several groups of buffer rings 4 enables the pressure to be evenly distributed on the contact surface, avoiding excessive force and reducing the risk of breakage.

[0033] The working process of the present invention is as follows: first, the base 1 connects the two sets of support plates 2. When polishing the surface of the optical glass, the material of the nanoparticles is silicon dioxide. The nanoparticles are first mixed with an organic solvent to form a uniform nanosuspension 705, and the nanosuspension 705 is stored in a water tank 704 of the first gantry 6. Then, the nanosuspension 705 in the water tank 704 is extracted by a water pump 706 and sent to the spray water pipe 701 through a connecting hose 703. After filling the spray water pipe 701, the liquid will pass through four sets of spray heads 702 to evenly spread the nanoparticles. The suspension 705, with nanoparticles ranging in size from 1 to 100 nanometers, is sprayed onto the glass surface. The first motor 5 drives the four sets of rotating rollers 3 to rotate, thereby driving the buffer ring 4 to rotate, slowly conveying the glass forward to the bottom of the polishing wheel 13. The second motor 10 is then fixed to the mounting plate 11 and drives the transmission shaft 12 through the output end to drive the polishing wheel 13 to rotate and polish the glass surface. The two sets of electric push rods 9 at the upper end of the second gantry 8 then drive the mounting plate 11 downward, thereby driving the polishing wheel 13 downward to contact the optical glass surface for polishing.

[0034] Then, through combination with the polishing wheel 13, the nanoparticles of the nanosuspension 705 can fill the tiny pits and scratches on the surface of the optical glass during the polishing process, and as the solvent evaporates, the distance between the nanoparticles decreases, the particles begin to aggregate and contact each other, forming a tighter structure, and during the drying process, the arrangement and structure of the nanoparticles will change to form a physically cross-linked network structure, which can effectively lock the particles and form a thin protective layer. The installation of two groups of support plates 2 can help to evenly distribute the load borne by the four groups of rotating rollers 3. Each group of rotating rollers 3 can be driven to rotate between the two groups of support plates 2 by the first motor 5. The rubber material of the buffer ring 4 has good elasticity and buffering properties. Several groups of buffer rings 4 enable the pressure to be evenly distributed on the contact surface. Through the compression and recovery of the buffer ring 4, the impact force can be dispersed at the moment of contact, reducing the direct impact on the optical glass. The above is the working principle of this automated optical crystal glass surface finishing device.
