Description

Technical Field

[0001] The utility model relates to the technical field of AR glasses production, in particular to a high-precision frame grinding device for AR glasses production. Background Art

[0002] AR glasses are a type of augmented reality glasses that can superimpose virtual images on real scenes, allowing users to see a mixture of virtual reality and the real world. AR glasses are composed of multiple components, one of which is the frame that can provide installation support for other components.

[0003] After searching, the announcement number is CN215470133U, and the name is a flexible grinding and polishing device for eyeglass frames, including a top plate and a bottom plate. Through research and analysis, it is found that although the angle of the grinding disc can be adjusted to prevent the bottom of the grinding disc from being unable to grind to the sides of the eyeglass frame, the following defects still exist to a certain extent.

[0004] For example, the above-mentioned device cannot rotate the fixed frame during the grinding process. When grinding the other side of the frame, the personnel need to manually reverse the frame, which affects the grinding efficiency and increases the labor intensity of the personnel. Moreover, it does not have the dust suction function and cannot collect the dust generated during the grinding process. The flying dust not only affects the health of the personnel, but also increases the difficulty of cleaning. In order to solve the above technical problems, we have designed a high-precision frame grinding device for AR glasses production. Utility Model Content

It solves the problem that personnel need to manually flip the frames, which affects the grinding efficiency and increases the labor intensity of personnel, and has no dust suction function, resulting in dust flying and affecting the health of personnel and being difficult to clean.

After rotating to the corresponding side, the stepper motor stops working, and then the other side is polished close to the polishing belt. This does not require manual flipping, which improves the polishing efficiency and reduces the labor intensity of the personnel.

[0014] 2. Turn the clamping screw clockwise to push the upper clamping plate to clamp and fix the frame body. The transmission motor drives the driving screw to rotate forward to move the frame body backward and contact the grinding belt.

[0022] See also Figure 5 The dust collecting mechanism 6 includes a dust collecting hood 22. By setting the dust collecting hood 22, the dust collecting area can be increased, and the dust can be collected more thoroughly. The rear side of the dust collecting hood 22 is fixedly connected to a dust filter box 24. The inner cavity of the dust filter box 24 is fixedly connected to a dust filter screen plate 23. The rear side of the dust filter box 24 is fixedly connected to a dust collecting fan 25 through bolts.

[0023] See also Figure 4 The clamping mechanism 12 includes a support frame 17, and the front and rear sides of the inner cavity of the support frame 17 are fixedly connected with guide slide bars 19. By setting the guide slide bars 19, it has a guiding function, which can make the upper clamping plate 18 move up and down more smoothly. The upper clamping plate 18 is slidably sleeved between the front and rear guide slide bars 19. The top of the upper clamping plate 18 is movably connected with a clamping screw 16. The top of the clamping screw 16 penetrates the top of the support frame 17 and is fixedly connected with a rotating plate. By setting the rotating plate, it can make it easier for personnel to rotate the clamping screw 16. The bottom of the inner cavity of the support frame 17 is fixedly connected with a lower clamping plate 20;

[0024] See also Figure 1 The inner cavity on the right side of the top of the base plate 1 is fixedly connected with a support slide bar 2. By setting the support slide bar 2, it has the function of supporting and limiting, and can make the mounting frame 11 move forward and backward more smoothly. The surface of the support slide bar 2 is slidably connected to the right side of the bottom of the mounting frame 11;

[0025] See also Figure 1The front side of the left side of the top of the base plate 1 is connected with a controller 3 by bolts, and the output end of the controller 3 is electrically connected to the stepping motor 5, the dust suction mechanism 6, the driving motor 7, the linear motor 8 and the transmission motor 21 respectively, so that the electrical equipment can be centrally controlled. The left and right sides of the top of the base plate 1 are provided with installation grooves;

[0026] See also Figure 1 and Figure 2 A through opening is provided at the rear side of the top of the base plate 1. By providing the through opening, the grinding belt 9 can be easily passed through the base plate 1. Support columns 15 are welded at the four corners of the bottom of the base plate 1.

[0027] When in use, connect the device to an external power source, control the transmission motor 21 through the controller 3 to drive the driving screw 4 to reverse, and the mounting frame 11 moves forward away from the grinding belt 9.

A large amount of dust will be generated during the grinding process. At this time, the dust suction fan 25 is controlled to extract the air in the dust filter box 24. The dust filter box 24 is in a negative pressure environment, so that the dust flying inside the dust hood 22 is sucked into the dust filter box 24, and the dust filter screen 23 filters the dust in the air and collects it in the dust filter box 24. This has a dust suction function, which prevents dust from flying everywhere and being inhaled into the body of people, reducing the difficulty of cleaning the dust. When one side of the frame body 14 is polished and the other side needs to be polished, the stepper motor 5 is controlled to drive the clamping mechanism 12 on the left to rotate, and the frame body 14 clamped in the clamping mechanism 12 rotates accordingly. When it rotates to the corresponding side, the stepper motor 5 stops working, and then approaches the polishing belt 9 to polish the other side. In this way, there is no need for personnel to manually flip it, which improves the polishing efficiency and reduces the labor intensity of personnel.

[0028] In summary: the high-precision frame grinding device for AR glasses production, through the coordinated use of the stepper motor 5, the dust suction mechanism 6, the drive motor 7, the linear motor 8, the grinding belt 9 and the clamping mechanism 12, solves the problem that personnel need to manually flip the frame, which affects the grinding efficiency and increases the labor intensity of personnel, and has no dust suction function, resulting in dust flying and affecting the health of personnel, and is difficult to clean.
