The design of this makeup mirror aims to improve driving comfort and safety.

[0032] Such as Figures 1 - 8 , the automated grinding operation process of the observable lens can be seen; Placing the lens: Precisely and fixedly assemble the flange connection seat 101 at the designated position on the processing table to ensure its stability without shaking; manually place the cut sun visor lens at the central area on the top of the lens seat 3, and start the centering adjustment function through the pre-set program control system to quickly complete the position calibration and centering positioning of the lens above the seat; gloves need to be worn during the operation; The method of position calibration and centering positioning: Start the control motor 303 to make it start running, drive the two groups of meshing control gears 302 to rotate synchronously, and then drive the four groups of racks 311 to move smoothly outwards along the slide rail through the gear transmission structure. At the same time, with the linkage effect of the connecting swivel seat 310, the hexagonal shaft 307 is evenly pushed outwards from the fixed position, so that the clamping strip 308 gradually unfolds under the drive of the mechanical structure; then start the steering motor 304, and its output shaft drives the drive worm 312 to rotate at high speed. The four groups of drive worms 312 achieve multi-axis coordinated rotation through the synchronous transmission mechanism composed of bevel gears, and then drive the groups of driven worm wheels 306 to rotate synchronously. The rotation of the driven worm wheels 306 is transmitted to the rotating sleeve 305, so that the rotating sleeve 305 drives the hexagonal shaft 307 to accurately rotate half a circle, and rotates the clamping strip 308 upwards to a predetermined angle; then the control motor 303 executes the reverse instruction, drives the four groups of racks 311 to retract inwards along the original path, makes the clamping strip 308 slowly move towards the side of the lens, and uses the grinding strip 209 installed on the clamping strip 308 to accurately fit the side of the lens, and stably center and fix the lens through the action of mechanical force; The operation control panel retracts the lifting and telescoping cylinder 4, driving the closed top seat 5 to descend vertically until the closed top seat 5 is in close contact with the upper surface of the edging die frame 2; the pressing telescoping cylinder 6 is started, and the pressing piece at its telescoping end presses evenly on the top surface of the lens to form a multi-point support and fixation structure; then, in accordance with the preset program, reverse the previous mechanical action steps, gradually reset the clamping strip 308, move it outward and rotate it downward to the specified position to ensure that the clamping strip 308 completely disengages from the lens area and avoid interfering with subsequent edging operations; if the clamping strip 308 directly contacts the lens, it may be affected by protruding structures such as burrs, causing the lens to shift. Therefore, a rubber pad 309 is used for contact, and the influence of burrs can be avoided through elasticity. Edge grinding operation: Start the side telescoping cylinder 201, push the transmission frame 202 to slowly approach the edge of the lens along the horizontal guide rail; start the edging motor 204 to run at high speed, the output shaft of the motor drives the transmission wheel 205 to rotate, the transmission wheel 205 drives the drive rod 206 to rotate, the rotation of the drive rod 206 drives the vertical chute 210 to rotate around the axis, so that the edging strip 209 installed on the chute makes a rapid reciprocating linear motion in the edging track 207. When the edging track 207 approaches the edge of the lens as the transmission frame 202 moves, the high-speed moving edging strip 209 efficiently grinds the edge of the lens; after completing the edge grinding process, control the side telescoping cylinder 201 to contract and reset, and make the transmission frame 202 return to the initial position. Corner grinding operation: Start the corner grinding motor 508, its output shaft drives the corner grinding wheel 507 to rotate at a set speed at high speed, and the abrasive on the surface of the grinding wheel forms a grinding surface; start the vertical telescoping cylinder 504, and its piston rod pushes the corner grinding device 505 to move downward along the vertical guide rail, so that the high-speed rotating corner grinding wheel 507 accurately aligns with the corner area of the lens, and the corner of the lens is finely ground through the grinding action of the corner grinding wheel 507. This step adopts a process design of separate grinding of the edge and the corner, so that the two do not interfere with each other during the grinding process, ensuring an automated and complete grinding effect. Dust collection and treatment: Start the fan 502 to exhaust air downward, form an air flow channel inside the equipment, and the air is discharged after passing through the magnetic adsorption net strip 103 installed at the bottom, forming a continuous air circulation system; the dust generated during the edging operation moves downward with the air under the action of the air flow and is effectively intercepted by the magnetic structure of the magnetic adsorption net strip 103, preventing the dust from spreading into the working environment; after completing all edging processes, first place a dust collection container at an appropriate position below the magnetic adsorption net strip 103, and then remove the magnetic adsorption net strip 103, and the dust will automatically fall off and drop into the container below to complete the recycling process.

[0033] Embodiment 2: On the basis of Embodiment 1, the side telescopic cylinder 201, the lifting telescopic cylinder 4, the vertical telescopic cylinder 504, and the pressing telescopic cylinder 6 can be replaced by an electric cylinder, a pneumatic cylinder, or any other driving member that can achieve a similar telescopic driving function according to actual use requirements, as long as it can be telescoped and does not interfere with the edge grinding step; For example, the telescopic cylinder 6 is an electric cylinder or a hydraulic cylinder, and the side telescopic cylinder 201 is a pneumatic cylinder.

[0034] Embodiment 3: On the basis of Embodiment 1, a stable transmission method such as a chain can be used between the steering motor 304 and the driving worm 312.

[0035] Specific usage method and function of this embodiment: In the present invention, when in use, the flange connection seat 101 is fixedly assembled on the processing table; Place the lens of the cut sun visor on the top of the lens seat table 3, and then center it through program control; Start the control motor 303 to drive the two groups of control gears 302 to rotate. Use the two groups of control gears 302 to drive the four groups of racks 311 to move outwards. Cooperate with the connecting turntable 310 to push the hexagonal shaft 307 outwards, unfold the clamping strip 308, and then start the steering motor 304 to drive the driving worm 312 to rotate; the four groups of driving worms 312 are synchronously driven by bevel gears and rotate synchronously to drive each group of driven worm wheels 306 to rotate synchronously. The driven worm wheel 306 drives the rotating sleeve 305 to rotate, and the rotating sleeve 305 drives the hexagonal shaft 307 to rotate half a circle to turn the clamping strip 308 upwards; then reverse the control motor 303 to drive the four groups of racks 311 to retract, move the clamping strip 308 to the side of the lens, and use the edge grinding strip 209 to fit the side of the lens to center the lens; Then contract the lifting telescopic cylinder 4 to lower the closed top seat 5. The closed top seat 5 is fixedly attached to the edge grinding die frame 2. Start the pressing telescopic cylinder 6, and use the pressing piece at the telescopic end of the pressing telescopic cylinder 6 to fix the top of the lens. At this time, reverse the previous steps to reset the clamping strip 308, so that the clamping strip 308 moves outwards and turns downwards to avoid affecting edge grinding; Start the side telescopic cylinder 201 to move the transmission frame 202 closer to the side of the lens. Start the edge grinding motor 204 to drive the transmission wheel 205 to rotate. The transmission wheel 205 drives the driving rod 206 to rotate. Use the driving rod 206 to drive the vertical sliding groove 210 to move, so that the edge grinding strip 209 moves rapidly back and forth in the edge grinding track 207 to produce a grinding effect. Furthermore, when the edge grinding track 207 fits the side of the lens, grind the side of the lens; After completing the side grinding, contract the side telescopic cylinder 201 to reset; Then start the corner grinding motor 508 to drive the corner grinding wheel 507 to rotate, start the vertical telescopic cylinder 504 to move the corner grinder 505 downward, and use the corner grinding wheel 507 to grind the corners of the lens, so as to grind the corners of the lens and achieve complete grinding; The above steps separately grind the side and arc corners of the lens without affecting each other, achieving automated complete grinding; Start the fan 502 to extract air downward, and the air passes through the magnetic adsorption mesh strip 103 and is discharged to generate a cycle; the dust generated during edge grinding moves downward along with the air flow and is intercepted by the magnetic adsorption mesh strip 103. After edge grinding is completed, a collection container is set below the magnetic adsorption mesh strip 103, and then the magnetic adsorption mesh strip 103 is removed, so that the dust automatically falls off and drops into the container to complete the recovery; Then raise the closed top seat 5 to take out the lens.
