Description

Technical Field

[0001] This utility model relates to the field of glass surface polishing technology, and in particular to an optical glass surface polishing device based on ultrafast laser. Background Technology

[0002] Optical glass is a glass material used to manufacture optical components such as lenses, prisms, mirrors, and windows for optical instruments or mechanical systems. It has certain hardness, strength, and wear resistance, and can withstand grinding, polishing, and other operations during optical processing, as well as external forces that may be applied during use. It is not easily damaged by scratches, cracks, or other defects.

[0003] In existing technologies, the heat generated during high-speed rotation when polishing optical glass can cause a chemical reaction between the abrasive and the glass. Therefore, traditional polishing processes require cleaning after polishing. Similarly, abrasive materials, powders, and polishing fluids are consumed during the polishing process and cannot be reused, thus causing environmental pollution.

[0004] An existing patent (publication number: CN211305211U) discloses a laser polishing device. First, the glass product to be polished is placed manually on the second platform of the conveying device. The second Z-axis linear module and the second Y-axis linear module work together to drive the vacuum nozzle of the robot to pick up the glass product. Then, the X-axis linear module, the first Y-axis linear module, the second Z-axis linear module and the second Y-axis linear module work together to drive the vacuum nozzle to place the glass product on the vacuum adsorption rotating fixture.

[0005] To address the aforementioned issues, while existing patents offer solutions that can displace and adjust the glass through the cooperation of components such as a second stage, these solutions are only suitable for smaller, miniature optical glasses in practical use. They are unusable for larger optical glasses, resulting in overly limited effectiveness. Summary of the Invention

[0006] The purpose of this invention is to provide an optical glass surface polishing device based on ultrafast laser, which can support a large optical glass blank for polishing, avoiding the need to cut several pieces of optical glass of the same size and polish them in stages, which would result in slow processing efficiency. This device is suitable for use in factories or production lines and can improve the processing efficiency of optical glass, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an optical glass surface polishing device based on ultrafast laser, comprising a dustproof shell, a control terminal embedded in one side of the outer wall of the dustproof shell, and a laser polishing equipment body fixedly installed at the top of the dustproof shell, a polishing head embedded in one end of the laser polishing equipment body that penetrates into the dustproof shell, and fixed plates fixedly installed at both ends of the dustproof shell, with an adjustment mechanism provided on one side of the fixed plate;

[0008] The adjustment mechanism includes a first motor, which is fixedly installed on the outer wall of the fixed plate.

[0010] Preferably, a second threaded rod extends from one end of the sliding table into the sliding plate, and a second motor is fixedly installed at one end of the second threaded rod.

[0011] Preferably, a conveying groove is provided on one side of the fixing plates at both ends of the dustproof shell, and a cleaning mechanism is provided inside the conveying groove.

[0012] Preferably, the cleaning mechanism includes a spring, which is fixedly installed above the inside of the conveying groove, and a support rod extends through the inside of the spring. An abutment block is fixedly installed at the bottom end of the spring, and a first soft brush is embedded at the bottom end of the abutment block.

[0013] Preferably, a fixing frame is fixedly installed at the bottom end of the sliding plate, and a second soft brush is embedded at the bottom end of the fixing frame.

[0014] Preferably, a bearing shell is fixedly installed at one end of the fixing plate, and a storage shell is slidably connected inside the bearing shell.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, after the optical glass is adsorbed and fixed by the vacuum suction cup body embedded in the sliding stage, it can be adjusted in multiple axes after entering the dustproof shell. It is suitable for polishing different positions of the optical glass. At the same time, it can support larger optical glass blanks for grinding, avoiding the need to cut several pieces of optical glass of the same size and grind them in batches, which leads to slow processing efficiency.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a technical solution:

[0028] Please see Figures 1 to 3An optical glass surface polishing device based on ultrafast laser includes a dustproof shell 1. A control terminal 2 is embedded in one side of the outer wall of the dustproof shell 1. A laser polishing equipment body 3 is fixedly installed on the top of the dustproof shell 1. A polishing head 4 is embedded in one end of the laser polishing equipment body 3 that penetrates into the dustproof shell 1. Fixing plates 5 are fixedly installed at both ends of the dustproof shell 1. An adjustment mechanism 6 is provided on one side of the fixing plate 5. The adjustment mechanism 6 includes a first motor 601, which is fixedly installed on the outer wall of the fixing plate 5. The power of the first motor 601 is... A first threaded rod 602 is fixedly installed at the output end. A sliding plate 603 is slidably connected to the outer wall of one end of the first threaded rod 602 that passes through the fixed plate 5. A groove 604 is opened on the outer wall of one end of the sliding plate 603 that passes through the fixed plate 5. A sliding table 605 is slidably connected inside the groove 604. A vacuum suction cup body 606 is embedded at the top of the sliding table 605. A second threaded rod 607 extends out from the inside of one end of the sliding table 605 that passes through the sliding plate 603. A second motor 608 is fixedly installed at one end of the second threaded rod 607.

[0029] By adopting the above technical solution, the sliding plate 603 slides inside the fixed plate 5 and the dustproof shell 1 through the cooperation of the first motor 601 and the first threaded rod 602. Through the cooperation of the second motor 608 and the second threaded rod 607, the sliding table 605 slides through the sliding groove 604. The sliding table 605 is adsorbed by the vacuum suction cup body 606 to avoid loosening or displacement during the movement. It can support larger and wider optical glass to pass through the dustproof shell 1 and be polished by the laser polishing equipment body 3. Therefore, it is suitable for polishing and grinding larger optical glass blanks in factories or production lines, avoiding the troublesome need to grind again after dividing into several small pieces, and improving the overall processing efficiency.

[0030] Specifically, such as Figure 1 , Figure 4 and Figure 5 As shown, a conveying groove 7 is provided on one side of the fixed plates 5 at both ends of the dustproof shell 1. A cleaning mechanism 8 is provided inside the conveying groove 7. The cleaning mechanism 8 includes a spring 801. The spring 801 is fixedly installed inside the upper part of the conveying groove 7. A support rod 804 extends out of the inside of the spring 801. An abutment block 802 is fixedly installed at the bottom end of the spring 801. A first soft brush 803 is embedded at the bottom end of the abutment block 802. A fixing frame 805 is fixedly installed at the bottom end of the sliding plate 603. A second soft brush 806 is embedded at the bottom end of the fixing frame 805. A bearing shell 807 is fixedly installed at one end of the fixed plate 5. A storage shell 808 is slidably connected inside the bearing shell 807.

[0031] By adopting the above technical solution, when the optical glass enters and exits the dustproof shell 1, the spring 801 elastically pushes the abutment block 802 to allow the first soft brush 803 to clean the optical glass, preventing the adsorbed dust from affecting the polishing effect. At the same time, it cleans up the debris generated during polishing. This dust will fall inside the dustproof shell 1, and under the support of the support rod 804, the spring 801 is prevented from bending and affecting the stability of the abutment block 802. When the sliding plate 603 moves, the fixing frame 805 drives the second soft brush 806 to clean the bottom of the inside of the dustproof shell 1, and pushes the dust into the collection shell 808 inside the bearing shell 807 for unified collection, which is convenient for unified cleaning later.

[0032] Working principle: The main body 3 of the laser polishing equipment consists of an ultrafast laser generation system, a beam transmission and focusing system, and a CCD camera system. The optical glass is polished by the emitting end embedded in the polishing head 4, which is a conventional technology and will not be elaborated further. The entire polishing device is controlled by a program-programmed control terminal 2. The dust cover 1 prevents external factors from affecting the polishing process. A first motor 601 embedded in the fixing plate 5, via a first threaded rod 602, moves the sliding plate 603, which supports the sliding stage 605. The other end of the sliding plate 603 is slidably connected to another fixing plate 5 via a locking block and slot. Simultaneously, the sliding stage 605, through the cooperation of a second motor 608 and a second threaded rod 607, slides along the sliding groove 604 on the sliding plate 603. It can be moved by a vacuum suction cup. After the body 606 adsorbs the optical glass, it enters the dustproof shell 1 and is adjusted according to the polishing position to support larger and wider optical glass. The spring 801 embedded in the conveying groove 7 elastically pushes the abutment block 802, allowing the first soft brush 803 to adsorb dust and clean the optical glass that enters and exits. The support rod 804 is fixed to the top of the abutment block 802. At the same time, a reserved hole is set inside the upper part of the conveying groove 7 corresponding to the support rod 804, so that the support rod 804 can be inserted when the spring 801 retracts. The support spring 801 is prevented from bending under force, which would affect the stability of the abutment block 802. At the same time, when the sliding plate 603 moves, it drives the fixing frame 805 to allow the second soft brush 806 to slide against the bottom of the dustproof shell 1, sweeping out dust and other particles and collecting them in the collection shell 808 inside the carrier shell 807.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
