Abstract
Description
Technical Field
[0001] This utility model belongs to the field of optical glass lens processing technology, specifically relating to a laser cutting device for optical glass lenses. Background Technology
[0002] Currently, the cutting of finished optical glass lenses in the market is still mainly done by traditional milling or blade cutting. This method is affected by tooling and processes, which can easily cause edge chipping and dimensional defects. In addition, cutting fluid needs to be continuously sprayed during processing, resulting in difficult-to-clean oil stains in the environment. After the lens is cut, it needs to be cleaned, which is not only inefficient but also greatly increases the manufacturing cost.
[0003] Patent application number 202421756958.9 discloses a laser cutting device, including a platform, a swing mechanism, a fixing fixture, and a cutting mechanism. The swing mechanism includes a first swing component and a second swing component. The first swing component is disposed on the platform, the second swing component is disposed on the first swing component, the fixing fixture is disposed on the second swing component, and the workpiece to be cut is fixedly disposed on the fixing fixture. The first swing component can drive the second swing component to swing the fixing fixture along a first circumferential direction, and the second swing component can drive the fixing fixture to swing along a second circumferential direction.
[0004] The aforementioned laser cutting device uses a swing mechanism to make the glass lens perpendicular to the laser beam. However, during the swinging process, the laser beam will reciprocate at the glass cutting point, and the continuous movement will cause the glass lens to shake, resulting in poor stability in cutting the glass lens and cutting errors. Utility Model Content
[0005] (1) Technical problems to be solved
[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a laser cutting device for optical glass lenses. This laser cutting device for optical glass lenses aims to solve the technical problem that the glass lens shakes under the prior art, resulting in poor stability and cutting error in the glass lens cutting.
[0007] (2) Technical solution
[0008] To solve the above-mentioned technical problems, this utility model provides a laser cutting device for optical glass lenses. The laser cutting device for optical glass lenses includes a laser cutting equipment body and a positioning plate disposed above the laser cutting equipment body. The top of the laser cutting equipment body is provided with a laser cutting platform for supporting the positioning plate. Both ends of the laser cutting platform are equipped with positioning plates for fixing the positioning plate. Multiple optical glass lens bodies are embedded in the top of the positioning plate.
[0009] When using this technical solution, a positioning disk is set at the top of the main body of the laser cutting equipment. The positioning protrusion at the bottom of the positioning disk fits into the gap of the laser cutting platform to maintain lateral positioning. The positioning plate on the laser cutting platform fits into the groove to maintain longitudinal positioning of the positioning disk. This keeps the positioning disk stable at the top of the laser cutting platform and also stable by fitting the optical glass lens body into the receiving groove. This prevents the optical glass lens body from shaking during the cutting process and keeps it stable. By setting multiple first mark points at the top of the positioning disk and multiple second mark points at the top of the optical glass lens body, the CCD camera on the laser cutting component can use the first and second mark points to locate the positioning disk and the optical glass lens body, thereby improving the accuracy of cutting the optical glass lens body.
[0010] Preferably, a laser cutting component is disposed above the main body of the laser cutting equipment, and a CCD camera is mounted at the bottom of the laser cutting component.
[0011] Furthermore, positioning protrusions are symmetrically fixed on both sides of the bottom end face of the positioning disk, and the positioning protrusions are fitted into the gap of the laser cutting platform.
[0012] Furthermore, the top of the positioning disk has multiple receiving slots arranged in a rectangular array, and the optical glass lens body is fitted into the receiving slots.
[0013] Furthermore, the top of the positioning disk is provided with grooves at equal intervals that communicate with the receiving groove, and the positioning plate is inserted into the grooves.
[0014] Furthermore, the outer wall of the laser cutting platform is equipped with fastening bolts, which are threaded into the positioning plate.
[0015] Furthermore, the top of the positioning disk is provided with multiple first Mark points, and the top of the optical glass lens body is transferred with second Mark points.
[0016] (3) Beneficial effects
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] This invention features a positioning disk at the top of the laser cutting equipment body. The positioning protrusion at the bottom of the positioning disk fits into the gap of the laser cutting platform to maintain lateral positioning. The positioning plate on the laser cutting platform fits into the groove to maintain longitudinal positioning of the positioning disk. This keeps the positioning disk stable at the top of the laser cutting platform. Furthermore, the optical glass lens body fits into the receiving groove to maintain stability, thus preventing the optical glass lens body from shaking during the cutting process and keeping it stable.
[0019] By setting multiple first mark points on the top of the positioning disk and multiple second mark points on the top of the optical glass lens body, the CCD camera on the laser cutting component can improve the accuracy of cutting the optical glass lens body by using the first mark points and the second mark points to locate the positioning disk and the optical glass lens body.
