Description

Technical Field

[0001] The present application relates to the technical field of optical lenses, and in particular to an automatic scoring and cutting machine for optical lenses. Background Art

[0002] Optical lenses are widely used in various testing equipment, such as surface topography measuring instruments, defect detectors, etc. During the production process of optical lenses, it is often necessary to cut the glass sheets with a laser scribing machine, and then grind and process the resulting blank lenses.

[0003] The laser scribing machine utilizes a high-energy laser beam to irradiate the surface of the workpiece, causing the irradiated area to partially melt and vaporize, thereby achieving the purpose of scribing. After the cutting is completed, the glass plate is cooled by cold air. At this time, the heating and cooling will produce a stress field. The stress generated by the rapid temperature change will cause micro-cracks in the glass and expand to the cutting gap, thereby completing the cutting of the blank lens. However, in actual situations, the blank lens that has been cut is not easy to remove from the glass plate. The prior art divides the scraps into multiple small pieces to facilitate the separation of the blank lens from it. However, this results in a longer cutting time for the blank lens and easily reduces the production efficiency of the optical lens. In order to reasonably improve this problem, the present application proposes an automatic scribing and cutting machine for optical lenses. Utility Model Content

[0004] The purpose of the present application is to solve the technical problem that the existing technology cuts the scraps into multiple small pieces to facilitate the separation of the blank lenses from them, but this results in a long time spent in cutting the blank lenses and easily reduces the production efficiency of the optical lenses.

A plurality of blanking openings are opened on the bearing surface. The blanking openings are connected to the flow channels one by one, and sealing rings are laid along the edges of the blanking openings.

[0010] The air extraction component is arranged on the processing table and is used for extracting a plurality of flow channels into negative pressure.

[0011] Furthermore, a collection box is movably inserted in the negative pressure chamber, the flow channel is constructed on the collection box, and an interception net is installed inside the collection box.

[0012] Furthermore, sealing pads are provided on both side edges of the flow channel.

[0013] Furthermore, a buffer mechanism is provided on the top of the interception net, which is used to buffer the falling blank lenses.

[0014] Furthermore, the buffer mechanism includes a flexible plate installed on the interception net, and a plurality of through holes are configured on the top of the flexible plate.

[0015] Furthermore, the top of the flexible plate is constructed with enclosures along the circumference, and the multiple enclosures are connected end to end in sequence, and the blanking port is located in the middle of the multiple enclosures.

[0016] Furthermore, the inner side surfaces of the enclosure are all constructed with inclined surfaces, and the spacing between the multiple inclined surfaces gradually decreases from top to bottom.

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0026] like Figure 1-Figure 5 As shown, an automatic optical lens dicing and cutting machine proposed in one embodiment of the present application includes:

[0027] A processing table 1, the top of which is provided with a bearing surface 2, the bearing surface 2 is used for placing glass plates;

[0028] The mounting frame 3 is connected to the processing table 1, and is provided with a cutting assembly 4 and a cooling assembly 5, wherein the cutting assembly 4 includes a mounting plate 401 slidably mounted on the mounting frame 3 in a vertical direction, the mounting plate 401 is arranged on the top of the bearing surface 2, a screw rod 402 is rotatably mounted on the mounting frame 3, and the screw rod 402 is threadedly matched with the mounting plate 401, a first motor 403 is mounted on the mounting frame 3, and its output end is connected to the screw rod 402, when the first motor 403 is working, the mounting plate 401 can be driven to slide toward the bearing surface 2 through the screw rod 402, a plurality of rotating rods 404 are rotatably mounted on the bottom of the mounting plate 401, a second motor 405 is mounted on the top of the mounting plate 401, and a first spur gear 406 is mounted on the output end of the rotating plate 403. The top of the rod 404 is connected to a second spur gear 407 meshing with the first spur gear 406. The bottom of the rotating rod 404 is installed with a laser beam cutting head 408. When the second motor 405 is working, it can drive multiple rotating rods 404 to rotate synchronously. At this time, the laser beam cutting head 408 can perform circular cutting on the glass plate. The cooling component 5 includes multiple cold air pipes connected to the output end of the external cold air blower, which are used to spray cold air. After the circular cutting is completed, the cooling component 5 can be used to cool the glass plate. At this time, heating and cooling will generate a stress field. The stress generated by the rapid temperature change will cause micro cracks in the glass plate and expand to the cutting gap, thereby completing the cutting of the blank lens;

[0029] A negative pressure chamber 6 is constructed inside the processing table 1. A plurality of flow channels 7 are separated inside the negative pressure chamber 6. The plurality of flow channels 7 are not connected to each other. A plurality of blanking ports 8 are provided on the bearing surface 2. The plurality of blanking ports 8 are coaxial with the plurality of rotating rods 404 respectively. The inner diameter of the blanking ports 8 is larger than the outer diameter of the blank lens. A plurality of cold air ducts are respectively directed toward the plurality of blanking ports 8. The blank lens can enter the flow channel 7 through the blanking ports 8. The edges of the blanking ports 8 are provided with sealing rings 9. The sealing rings 9 are silicone rings. When the glass plate is placed on the bearing surface 2, the bottom surface of the glass plate will exert pressure on the sealing ring 9.

[0030] The exhaust assembly 10 is arranged on the processing table 1 and is used to evacuate the multiple flow channels 7 to a negative pressure. After the cutting is completed, since the blanking port 8 is blocked by the glass plate and the air cannot enter the blanking port 8 through the gap between the two under the action of the sealing ring 9, the multiple flow channels 7 can be evacuated to a negative pressure through the exhaust assembly 10. At this time, the outside air can slowly enter the blanking port 8 from the cutting gap between the blank lens and the scrap, and the blank lens can move toward the blanking port 8 under the action of the atmospheric pressure and slowly separate from the scrap of the glass plate;

[0031] The present application adopts the design of the negative pressure chamber 6. After the cutting is completed, the multiple flow channels 7 can be evacuated into negative pressure through the vacuum component 10. At this time, the cut blank lens can move toward the blanking port 8 under the action of atmospheric pressure and slowly separate from the scraps of the glass plate. Compared with the prior art, the present application does not need to cut the scraps, which can effectively reduce the cutting time of the blank lens, thereby increasing the production efficiency of the optical lens, and is practical.

[0032] like Figure 1-Figure 5 As shown, in some embodiments, a collecting box 11 is movably inserted into the negative pressure chamber 6, and the collecting box 11 is horizontally inserted into the negative pressure chamber 6. The flow channel 7 is constructed on the collecting box 11. When the negative pressure chamber 6 completely accommodates the collecting box 11, the flow channel 7 is respectively connected with multiple drop-out ports 8. At this time, the air inside the flow channel 7 can be extracted by the vacuum assembly 10, and an interception net 12 is installed therein. The interception net 12 is made of polyethylene material. The interception net 12 is designed to intercept the blank lens, making it difficult for it to pass through the flow channel 7. When the collecting box 11 is pulled out of the negative pressure chamber 6, the blank lens in the flow channel 7 can be taken out.

[0033] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, sealing pads 13 are laid on both side edges of the flow channel 7, where the two sides are the top side and the bottom side of the flow channel 7, and the sealing pads 13 are silicone pads. After the collecting box 11 is inserted into the negative pressure chamber 6, the sealing pads 13 on both sides can respectively contact the inner top surface and the inner bottom surface of the negative pressure chamber 6, thereby improving the air tightness of the flow channel 7 and the negative pressure chamber 6.

[0034] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, a buffer mechanism 14 is provided on the top of the interception net 12, which is used to buffer the falling blank lens. When the blank lens is separated from the scraps under the action of pressure, its falling speed is relatively fast. By adopting the design of the buffer mechanism 14, the impact force of the blank lens when falling can be buffered, making it less likely to be damaged.

[0035] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the buffer mechanism 14 includes a flexible plate 1401 installed on the intercepting net 12. The flexible plate 1401 is a silicone plate, and a plurality of through holes 1402 are configured on the top thereof. The through holes 1402 allow air to pass through, so as to facilitate the flow channel 7 to be pumped into a negative pressure. When the blank lens falls on the flexible plate 1401, the impact force generated by the blank lens can be absorbed by the flexible plate 1401, thereby playing a role in buffering the blank lens.

[0036] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, a surrounding plate 1403 is constructed along the top of the flexible plate 1401, and the extension direction of the surrounding plate 1403 is perpendicular to the flexible plate 1401. Multiple surrounding plates 1403 are connected end to end in sequence to enclose a space, and the blanking port 8 is located in the middle of the multiple surrounding plates 1403. During the falling process, the blank lens is easy to contact with the inner wall of the flow channel 7, thereby separating it from the inner wall of the flow channel 7, and the blank lens can be further protected.

[0037] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the inner side surfaces of the enclosures 1403 are constructed with inclined surfaces 1404, and the spacing between the multiple inclined surfaces 1404 gradually decreases from top to bottom. With such a design, when the blank lens falls on the flexible plate 1401, it can enter the spacing between the multiple inclined surfaces 1404. When it collides with the multiple inclined surfaces 1404, it can force the multiple enclosures 1403 to deform, and through the friction force generated when the multiple enclosures 1403 are reset, it can fix it between the multiple enclosures 1403, so that it is not easy to be ejected due to impact.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, the exhaust component 10 includes a negative pressure fan 1001 installed on the outside of the processing table 1, on which a plurality of exhaust pipes 1002 are installed, and the ends of the plurality of exhaust pipes 1002 all penetrate the negative pressure chamber 6, and the ends of the plurality of exhaust pipes 1002 penetrate the inner bottom surface of the negative pressure chamber 6 from bottom to top, and respectively correspond to the plurality of drop openings 8. After the collecting box 11 is inserted into the negative pressure chamber 6, the plurality of flow channels 7 can be respectively connected to the plurality of exhaust pipes 1002, and a flow sensor 1003 is installed on the exhaust pipe 1002. The flow sensor 1003 is an existing gas flow sensor 1003. The flow rate of the gas in the exhaust pipe 1002 can be monitored by the flow sensor 1003. After the blank lens falls into the flow channel 7, the flow rate in the exhaust pipe 1002 increases. At this time, the flow sensor 1003 sends a signal to close the corresponding exhaust pipe 1002 to avoid waste of resources.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
