Abstract

According to the edge grinding process of the full-automatic core taking machine, synchronous or step-by-step grinding on the edge of the lens is achieved by controlling the first edge grinding device and / or the second edge grinding device. According to the technology, the collaborative operation capacity of the edge grinding devices on the two sides is fully utilized, and efficient machining of a plurality of areas such as the convex face periphery, the concave face periphery, the first edge and the second edge can be completed in the single-time clamping state. In the synchronous grinding mode, the two edge grinding devices can act on the same part of the lens at the same time, and the machining time is remarkably shortened; in the step-by-step grinding mode, all the devices work orderly according to a preset path, interference is avoided, and complete forming of a complex contour is ensured. As the lens does not need to be repositioned or turned over in the whole process, accumulative errors caused by repeated clamping are effectively eliminated, and the edge size precision, the roundness consistency and the surface quality are greatly improved.

Description

[Technical Field] This invention relates to the field of lens edging technology, and in particular to a fully automatic core extraction machine edging process. [Background Technology] In the field of optical component manufacturing, lens edging is a critical process that determines the edge quality, dimensional accuracy, and subsequent assembly performance of the finished product. Traditional lens edging equipment generally uses a single edging device, requiring multiple rotations and flips of the workpiece or complex adjustments to the grinding wheel to sequentially grind the outer periphery of the convex surface, the outer periphery of the concave surface, and different edge areas. This method not only results in long processing cycles and low efficiency, but also easily introduces cumulative errors due to repeated clamping or positioning, seriously affecting the roundness, coaxiality, and edge consistency of the lens, making it difficult to meet the high precision, high stability, and mass production requirements of modern optical systems. The limitations of a single grinding head are particularly pronounced in the processing of aspherical lenses or lenses with irregular edges. [Summary of the Invention] The purpose of this invention is to provide a fully automatic core-removing machine edge grinding process, which solves the problems of low processing efficiency, positioning error and insufficient edge accuracy in the existing single edge grinding device process.

[0004] A fully automated core removal and edge grinding process includes the following steps: S1. Loading and centering: The lens to be processed is transferred to the centering and clamping device through the loading and unloading device, and the centering and clamping device centers and clamps the lens. S2. Edge grinding: According to the lens specifications and process requirements, the first edge grinding device and / or the second edge grinding device move along the horizontal and vertical directions through their respective dual-axis moving components, so that their respective edge grinding wheels move to the target processing position. Then, the electric spindle is started to drive the edge grinding wheels to rotate, and the lens edge is ground synchronously or stepwise. S3. Retraction and Unloading: After grinding is completed, the first and / or second edge grinding devices retract to their initial positions, the centering clamping device releases the lens, and the finished product is taken out by the loading and unloading device, completing one processing cycle.

[0005] As described above, in the fully automated core-removing machine edge-grinding process, the lens edge includes a convex outer periphery, a concave outer periphery, a first edge, and a second edge.

[0006] As described above, in the fully automatic core extraction machine edge grinding process, in step S2, when the lens is being ground synchronously, the first edge grinding device and the second edge grinding device use their respective dual-axis moving components to move their respective edge grinding wheels synchronously to the outer periphery of the convex surface and the first edge, and jointly complete the outer periphery and edge grinding.

[0007] As described above, in the fully automatic core-removing machine edge grinding process, in step S2, when the lens is being ground synchronously, the first edge grinding device and the second edge grinding device use their respective dual-axis moving components to move their respective edge grinding wheels synchronously to the outer periphery of the concave surface, and jointly complete the outer periphery grinding.

[0008] As described above, in the fully automatic core extraction machine edge grinding process, in step S2, when the lens is being ground synchronously, the first edge grinding device and the second edge grinding device use their respective dual-axis moving components to move their respective edge grinding wheels synchronously to the second edge, and jointly complete the edge grinding.

[0009] As described above, in the fully automatic core extraction machine edge grinding process, in step S2, when the lens is ground in steps, the first edge grinding device moves the edge grinding wheel to the outer periphery of the convex surface and the first edge through its dual-axis moving component to complete single-step grinding; the second edge grinding device moves the edge grinding wheel to the outer periphery of the concave surface and the second edge in sequence through its dual-axis moving component to complete multi-step grinding.

[0010] As described above, in the fully automatic core extraction machine edge grinding process, in step S2, when the lens is ground in steps, the first edge grinding device moves the edge grinding wheel to the outer periphery of the concave surface through its dual-axis moving component to complete single-step grinding; the second edge grinding device moves the edge grinding wheel sequentially to the outer periphery of the convex surface, the first edge, and the second edge through its dual-axis moving component to complete multi-step grinding.

[0011] As described above, in the fully automatic core extraction machine edge grinding process, in step S2, when the lens is ground in steps, the first edge grinding device moves the edge grinding wheel to the second edge through its dual-axis moving component to complete single-step grinding; the second edge grinding device moves the edge grinding wheel sequentially to the outer periphery of the convex surface, the first edge, and the outer periphery of the concave surface through its dual-axis moving component to complete multi-step grinding.

[0012] As described above, in the fully automatic core extraction machine edge grinding process, the first edge grinding device and the second edge grinding device are respectively located on both sides of the centering clamping device, and are arranged symmetrically or diagonally relative to the clamping position of the centering clamping device.

[0013] As described above, in the fully automatic core removal machine edge grinding process, both the first edge grinding device and the second edge grinding device include an edge grinding assembly and a dual-axis moving assembly mounted on the frame for driving the edge grinding assembly to the clamping position of the centering clamping device; the edge grinding assembly includes a mounting base mounted on the dual-axis moving assembly, an electric spindle passing through the mounting base, and an edge grinding wheel located at the output end of the electric spindle.

[0014] This invention proposes a fully automated lens edge grinding process. By controlling a first and / or second edge grinding device, synchronous or step-by-step grinding of the lens edge can be achieved. This process fully utilizes the collaborative operation capability of the two edge grinding devices, enabling efficient processing of multiple areas, including the convex outer periphery, concave outer periphery, first edge, and second edge, in a single clamping operation. In synchronous grinding mode, the two edge grinding devices can simultaneously work on the same part of the lens, significantly shortening processing time. In step-by-step grinding mode, each device operates in an orderly manner along a preset path, avoiding interference and ensuring the complete shaping of complex contours. Since no lens repositioning or flipping is required throughout the process, the cumulative error caused by repeated clamping is effectively eliminated, significantly improving edge dimensional accuracy, roundness consistency, and surface quality. This process significantly improves processing efficiency and product yield while maintaining high precision, making it suitable for high-volume, high-consistency optical lens manufacturing scenarios.

Detailed Implementation Methods

[0016] This invention relates to a fully automated lens core grinding process. By controlling a first and / or second grinding device, it achieves simultaneous or step-by-step grinding of the lens edge. This process fully utilizes the collaborative operation of both grinding devices, enabling efficient processing of multiple areas, including the convex outer periphery, concave outer periphery, first edge, and second edge, in a single clamping operation. In synchronous grinding mode, the two grinding devices can simultaneously work on the same part of the lens, significantly shortening processing time. In step-by-step grinding mode, each device operates in an orderly manner along a preset path, avoiding interference and ensuring the complete shaping of complex contours. Since the lens does not need to be repositioned or flipped throughout the process, the cumulative error caused by repeated clamping is effectively eliminated, significantly improving edge dimensional accuracy, roundness consistency, and surface quality. This process significantly improves processing efficiency and product yield while maintaining high precision, making it suitable for high-volume, high-consistency optical lens manufacturing scenarios.

[0017] Furthermore, Figure 5-6 The lens shown includes a convex surface 100 and a concave surface 101; the lens edge includes a convex outer periphery a, a concave outer periphery b, a first edge c, and a second edge d.

[0018] Furthermore, in step S2, when the lens is being synchronously ground, the first edge grinding device 3a and the second edge grinding device 3b, through their respective dual-axis moving components 32, cause their respective edge grinding wheels 313 to move synchronously to the outer periphery a and the first edge c of the convex surface, jointly completing the outer periphery and edge grinding. Specifically, the first edge grinding device 3a and the second edge grinding device 3b can simultaneously contact the outer periphery a and the first edge c of the convex surface to perform double-sided synchronous grinding, thereby collaboratively completing the synchronous fine grinding of adjacent areas in a single clamping state.

[0019] Furthermore, in step S2, when the lens is being synchronously ground, the first edge grinding device 3a and the second edge grinding device 3b use their respective dual-axis moving components 32 to move their respective edge grinding wheels 313 synchronously to the concave outer periphery b, and jointly complete the outer periphery grinding.

[0020] Furthermore, in step S2, when the lens is being synchronously ground, the first edge grinding device 3a and the second edge grinding device 3b use their respective dual-axis moving components 32 to move their respective edge grinding wheels 313 synchronously to the second edge d, and jointly complete the edge grinding.

[0021] This invention, through a first grinding device 3a and a second grinding device 3b, can flexibly select different synchronous grinding modes according to the lens structure characteristics and process requirements: it can simultaneously process the convex outer periphery a and the first edge c, or it can grind the concave outer periphery b or the second edge d from both sides in a coordinated manner. All of these synchronous strategies are completed in a single clamping state, without the need to change tooling or reposition, significantly reducing idle travel and auxiliary time. Simultaneously, the coordinated operation of the two grinding wheels effectively balances cutting forces, suppresses vibration and thermal deformation, and improves edge contour accuracy and surface quality. Compared to traditional single-head grinding equipment that requires multiple posture adjustments for zone-by-zone processing, this solution, through its multi-mode synchronous grinding capability, significantly shortens the processing cycle, improves overall equipment efficiency and product consistency, and is particularly suitable for the mass production of high-precision optical lenses.

[0022] Furthermore, in step S2, when the lens is being ground in steps, the first edge grinding device 3a moves the edge grinding wheel 313 to the outer periphery a of the convex surface and the first edge c through its dual-axis moving component 32 to complete single-step grinding; the second edge grinding device 3b moves the edge grinding wheel 313 to the outer periphery b of the concave surface and the second edge d in sequence through its dual-axis moving component 32 to complete multi-step grinding.

[0023] Furthermore, in step S2, when the lens is being ground in steps, the first edge grinding device 3a moves the edge grinding wheel 313 to the outer periphery b of the concave surface through its dual-axis moving component 32 to complete single-step grinding; the second edge grinding device 3b moves the edge grinding wheel 313 sequentially to the outer periphery a of the convex surface, the first edge c, and the second edge d through its dual-axis moving component 32 to complete multi-step grinding.

[0024] Furthermore, in step S2, when the lens is being ground in steps, the first edge grinding device 3a moves the edge grinding wheel 313 to the second edge d through its dual-axis moving component 32 to complete single-step grinding; the second edge grinding device 3b moves the edge grinding wheel 313 sequentially to the convex outer periphery a, the first edge c, and the concave outer periphery b through its dual-axis moving component 32 to complete multi-step grinding.

[0025] This invention, by configuring a first edge grinding device 3a and a second edge grinding device 3b, can flexibly implement various step-by-step grinding modes according to the lens's geometry, edge complexity, and process requirements. For example, the first edge grinding device 3a can complete the single-step grinding of the convex outer periphery a and the first edge c in one go, while the second edge grinding device 3b can sequentially complete the multi-step fine grinding of the concave outer periphery b and the second edge d; or the first edge grinding device 3a can be dedicated to processing the concave outer periphery b, while the second edge grinding device 3b continuously processes the convex outer periphery a, the first edge c, and the second edge d; alternatively, the first edge grinding device 3a can grind the second edge d alone, while the second edge grinding device 3b efficiently covers the other three key areas. All of the above step-by-step grinding modes complete all edge processing in a single clamping state, without the need for flipping, repositioning, or changing fixtures, effectively avoiding the cumulative errors caused by repeated clamping. At the same time, by rationally allocating the processing tasks of each device, the parallel processing capability of the dual edge grinding system is fully utilized, while the risk of interference from grinding wheel movement is avoided, ensuring the complete forming of complex contours. Compared to the inefficient process of traditional single-head grinding equipment that requires switching postures in each zone and multiple advances and retreats, this solution significantly improves processing flexibility, cycle time efficiency, and edge consistency through intelligent task scheduling and orderly collaborative grinding in multiple zones. It is especially suitable for the mass production of optical lenses with asymmetrical structures, multiple chamfers, or high precision requirements.

Figure 3 The first edge grinding device 3a and the second edge grinding device 3b shown are respectively diagonally arranged relative to the centering clamping device 2 clamping station.

[0028] Furthermore, both the first edge grinding device 3a and the second edge grinding device 3b include an edge grinding assembly 31 and a dual-axis moving assembly 32 mounted on the frame 1 for driving the edge grinding assembly 31 to the clamping position of the centering clamping device 2.
