Description

Technical Field

[0001] The utility model relates to the technical field of optical lens milling and grinding, in particular to a saltpeter milling and grinding device for optical lenses. Background Art

[0002] Optical lenses are transparent materials with one or more curved surfaces made of optical materials such as glass or resin. Therefore, during production, optical lenses need to be milled with special nitrate milling equipment to ensure their precision. The milling precision of the nitrate milling equipment can reach the nanometer level. This ensures the milling stability and accuracy of circular optical lenses and avoids lens breakage caused by the milling process.

[0003] However, the existing saltpeter milling equipment still has the following defects: since the size of the worktable of the current saltpeter milling equipment is much larger than the size of the optical lens when in use, the optical lenses need to be manually loaded on the worktable of the equipment when they are milled one by one, and then unloaded again with the same process after milling. After each disassembly, the optical lens needs to be re-aligned with the equipment when it is re-fixed. As a result, frequent disassembly and alignment of each piece will reduce the milling efficiency of a large number of optical lenses, and thus significantly extend the milling cycle of the optical lenses.

[0025] The movable plate 31 can achieve a parallel effect with the components through its rectangular shape, and then use the square groove to combine with the components to drive the support column 32, the connecting body 33 and other components to move horizontally. The support column 32 can effectively improve the load-bearing stability of the connecting body 33 through its solid shape.

[0026] See also Figure 3 The present invention provides a saltpeter milling equipment for optical lenses, comprising: the lens locking member 35, a protrusion 351, a parallel plate 352, a solid block 353, a covering sleeve 354, a collecting chamber 355, and a jacket 356.

The rotating body at the bottom of the slide rod 64 can stably drive the milling head 65 to rotate, so that the milling head 65 can complete the milling operation of the optical lens in combination with the rotation effect.

[0030] The working principle of the utility model is described as follows:

[0031] First, the optical lens milling equipment can determine the position of the load-bearing platform 3 through the restraining block 2 of the base 1, and then the load-bearing platform 3 can be translated on the base 1 in combination with the restraining block 2, so that the upper part of the load-bearing platform 3 can be on the same vertical center line as the lower part of the milling body 6, so that the milling body 6 and the optical lens in the load-bearing platform 3 can be conveniently aligned and milled, and then the control host 4 can automatically set and control the milling body 6 through program programming, so that the milling body 6 can move left and right in the slide rail 5, so that it can mill a large number of optical lenses on the load-bearing platform 3 one by one. The one-by-one limited restraint of the load-bearing platform 3 can enable the milling body 6 to achieve the effect of non-stop operation, and at the same time avoid the need for re-alignment of the milling body 6 caused by the disassembly of a single group of lenses after milling, thereby reducing the milling efficiency of a large number of optical lenses;

[0032] Second, the movable plate 31 of the bearing platform 3 can be translated on the base 1 through the check block 2, and then the support column 32 on the movable plate 31 can determine the position of the connecting body 33, so that the lens locking piece 35 in the assembly rail 34 of the connecting body 33 can be vertically aligned with the milling body 6, so that a large number of lens locking pieces 35 can simultaneously load a large number of optical lenses, so that after the milling body 6 and a single group of optical lenses are accurately aligned, they can be moved left and right in the slide rail 5 with the support of the automated program. Therefore, the same spacing of the lens locking pieces 35 will not cause the milling position error, so that the milling body 6 can achieve the effect of continuous operation without stopping the machine, so that the milling efficiency of a large number of optical lenses can be effectively improved, and the phenomenon of re-alignment can be avoided. The milling body 6 can combine with the left and right sliding of the slide rail 5 to accurately mill the optical lenses of the lens locking pieces 35 in the assembly rail 34 one by one;

[0033] Third: The parallel plates 352 of the lens locking member 35 can be vertically fixed to the surface center of the connecting body 33 through the protrusions 351, and then the solid block 353 of the parallel plates 352 can determine the position of the cover sleeve 354, so that the collecting chamber 355 inside the cover sleeve 354 can allow the milling body 6 to penetrate vertically, so that after the jacket 356 in the collecting chamber 355 positions the optical lens, the debris generated when the milling body 6 enters the parallel milling of the optical lens will be accumulated in the collecting chamber 355, avoiding the situation that it is difficult to clean up later due to large-scale diffusion, and then after the optical lens of the single set of jackets 356 is milled, the milling body 6 is raised by the program to separate from the inside of the cover sleeve 354, and then combined with the slide rail 5 The tool 350 is moved into the next lens locking member 35 to mill other optical lenses, so that the operator can remove and replace the currently milled optical lens while milling other optical lenses. Since the position of the overall clamping sleeve 356 remains unchanged, the center point of the unmilled optical lens will not change after entering the clamping sleeve 356, so that the milling body 6 can stably and accurately mill the replaced optical lens during the cyclic movement and milling, thereby replacing the original re-tooling process and effectively improving the milling efficiency of the optical lens. Furthermore, the limitation of the cover sleeve 354 can prevent the operator from being affected by the splashing of debris generated when replacing the optical lens, so as to achieve the effect of protecting the operator's operation.

[0034] Fourth: the program box 62 of the milling body 6 can receive the data automation program set by the control host 4, and then the electric slider 61 in the center of the side can be precisely moved in parallel in the slide rail 5 in combination with the program. Therefore, the overall components of the program box 62 will move left and right with the electric slider 61. At the same time, the slide rod 64 of the limit ring 63 can drive the milling head 65 to interact up and down, so that the milling head 65 can vertically and precisely enter the lens locking part 35 to mill the optical lens and exit vertically. For this reason, the cooperation of the automated program and the slide rail 5 can greatly improve the practicality of the milling equipment and improve the efficiency of milling a large number of optical lenses.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] Therefore, no matter from which point of view, the embodiments should be regarded as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all changes that fall within the meaning and range of equivalents of the claims be included in the present invention.
