Description

Technical Field

[0001] This utility model relates to the field of aspherical optical lens processing technology, specifically to a self-cleaning aspherical optical lens forming mold. Background Technology

[0002] In the processing of aspherical optical lenses, the lens is usually fixed on a fixture and then cut or ground into shape using processing equipment (such as drill bits, grinding heads, etc.). However, existing processing methods have the following problems: 1. Fine dust generated during processing can easily float in the air and harm the health of operators if inhaled; 2. During high-speed cutting or grinding, the generated debris may fly into the surrounding environment, which not only increases the amount of cleaning work, but may also cause safety hazards such as scratches to operators.

[0003] To address the aforementioned problems, existing technologies have proposed several solutions. For example, patent CN212352498U discloses an optical lens processing apparatus that uses a structure including a fan, water tank, suction pipe, and suction hood to absorb dust into the water tank using negative pressure, thereby reducing the dust content in the air. Simultaneously, the apparatus also suppresses debris splashing through liquid spraying, thus improving the working environment. However, this solution still has the following drawbacks;

[0004] 1. Because the sprayed coolant or dust suppressant is not recovered and is directly lost, it not only increases processing costs, but may also lead to a slippery working environment, affecting operational safety;

[0005] 2. Because high-speed rotating drill bits or grinding heads can easily throw out liquid, and the splashed liquid requires additional cleaning by the staff, which will increase the workload of the staff. Utility Model Content

[0034] The coolant can be filtered after use through the filter holes on the filter box 24, so as to avoid the presence of debris generated during the grinding or processing of optical lenses in the coolant, and to prevent the pipes from being blocked by debris when transporting coolant.

[0035] In this embodiment, the auxiliary cleaning component 4 includes a transmission rod 41. The output shaft end of the drive motor 3 is rotatably connected to the transmission rod 41 through a worm gear and worm wheel. One end of the transmission rod 41 passes through the cooling pool 1 and the disc 21 in sequence and is rotatably connected to the cooling pool 1 and the disc 21 respectively.

[0036] The drive motor 3 drives the transmission rod 41 and the cleaning rod 42 to rotate. At this time, the cleaning rod 42 can start to clean the debris and coolant on the disc 21 into the filter box 24, which facilitates the subsequent filtration and thus achieves the cleaning of the disc 21.

[0041] Example 3

[0042] like Figures 1-8 As shown, based on the above embodiments, this embodiment further provides the following:

[0043] The cooling shielding assembly 7 includes a fixing block 71, which is fixedly connected to one side of the cooling pool 1. A bidirectional pneumatic rod 72 is fixedly connected inside the fixing block 71. A moving rod 73 is fixedly connected to the output end of the bidirectional pneumatic rod 72. An arc-shaped water baffle 74 is fixedly connected to one end of the moving rod 73. The cooling shielding assembly 7 also includes a cooling pump 75, which is fixedly connected to the bottom surface of the cooling pool 1. The input end of the cooling pump 75 is connected to the cooling pool 1 through a water inlet pipe 76. The output end of the cooling pump 75 is connected to a three-way pipe 78 through a drain pipe 77. The two ends of the three-way pipe 78 are respectively connected to arc-shaped nozzles 710 through diverter pipes 79. An arc-shaped nozzle 710 is fixedly connected to the top surface of the arc-shaped water baffle 74.

[0044] The two sets of arc-shaped waterproof discs 74 are driven to move relative to each other by the bidirectional pneumatic rod 72, so that the two sets of arc-shaped waterproof discs 74 form a circular water-blocking disc. At this time, the two sets of arc-shaped waterproof discs 74 can block the debris generated during grinding or processing, and prevent the debris from flying.

[0045] The opposing movement of the two sets of arc-shaped waterproof discs 74 drives the opposing movement of the two sets of arc-shaped nozzles 710, thereby forming a circular nozzle. At this time, under the action of the cooling pump 75 and the pipeline, the coolant in the cooling pool 1 can be sprayed onto the aspherical optical lens, which not only cools the optical lens, but also removes debris, preventing debris from remaining on the clamping assembly 5, thus cleaning the clamping assembly 5 and the aspherical optical lens.

[0046] Working principle and usage process of this utility model:

[0047] In use:

[0048] In use, firstly, the operator places the aspherical optical lens that needs to be processed (processing at this time refers to grinding or cutting, etc.) on the clamping plate 52. After placement, the operator rotates the bidirectional threaded rod 54. As the bidirectional threaded rod 54 rotates, the clamping groove 53 causes the two sets of jaws 55 to move in opposite directions. As the two sets of jaws 55 move in opposite directions, the aspherical optical lens can be clamped.

[0049] After clamping, the operator activates the bidirectional pneumatic rod 72. When the bidirectional pneumatic rod 72 operates, it drives two sets of moving rods 73 and the arc-shaped waterproof disc 74 to move in opposite directions. As the two sets of arc-shaped waterproof discs 74 move in opposite directions, they form a circular water-blocking disc. This movement also drives two sets of arc-shaped nozzles 710 to move in opposite directions, forming a circular spray ring. Once the arc-shaped water-blocking disc 74 and the arc-shaped nozzles 710 have moved to the designated position, the cooling pump 75 is activated. When the cooling pump 75 operates, it will... Under the action of the inlet pipe 76, the drain pipe 77, the tee pipe 78 and the diversion pipe 79, the coolant in the cooling pool 1 is drawn into the arc-shaped nozzle 710 and sprayed out through the arc-shaped nozzle 710. After being sprayed out, it will be poured onto the aspherical optical lens 6. At this time, the grinding head of the grinding equipment or the cutting head of the cutting equipment moves from top to bottom and slowly contacts the top surface of the aspherical optical lens 6 to process it. During the processing, the generated debris will be blocked by the two sets of arc-shaped baffles 74, and some of the debris will also be carried away by the sprayed coolant to avoid the debris from splashing.

[0050] When processing the aspherical optical lens 6, the operator can start the drive motor 3 according to the processing requirements. For example, the drive motor 3 is not needed during processing, but it can be started after processing is completed. When the drive motor 3 is working, it will start to drive the transmission rod 41 to rotate. When the rotation rod 41 rotates, it will drive the cleaning rod 42 to rotate. When the cleaning rod 42 rotates, it will clean the top surface of the disc 21 and scrape the debris and coolant on the disc 21 into the liquid flow hole 22. At this time, the debris in the coolant is filtered through the filter box 24, which facilitates the unified treatment of the debris in the later stage.

[0051] When it is necessary to clean the debris, first, pull the blocking rod 26. The blocking rod 26 will stretch and reset the damping rod 27. At the same time, the blocking rod 26 will no longer block the filter box 24. At this time, the staff can pull the filter box 24 off the U-shaped slide rail 23. After it is pulled off, the staff can easily clean the filter box 24.
