Description

Technical Field

[0001] This utility model relates to the field of chamfering equipment technology, and in particular to an automated chamfering and grinding device for lens edges. Background Technology

[0002] In the manufacturing process of optical lenses, edge chamfering is a crucial step to ensure safe assembly, eliminate stress concentration, and improve appearance quality. Traditional manual chamfering methods are inefficient, labor-intensive, and highly dependent on operator experience, making it difficult to guarantee product consistency and precision. Although some mechanized chamfering equipment exists, several problems remain in practical applications. For example, in the clamping process, common pneumatic or hydraulic clamps act directly on the lens surface, easily causing indentations or damage to the precision lens. Insufficient clamping stability can also cause the lens to slip or shift during high-speed rotation and grinding, affecting chamfering accuracy and even resulting in scrap. Furthermore, for lenses of different specifications or requiring specific chamfering angles, existing equipment often lacks a convenient and effective angle adjustment mechanism, necessitating tooling changes or complex mechanical adjustments, reducing equipment versatility and production efficiency. Utility Model Content

[0003] This utility model relates to an automated lens edge chamfering and grinding device. It positions the lens via a turntable, and an automatic clamping mechanism on a clamping frame (a clamping cylinder drives the clamping seat, which in turn drives the clamping roller / drive roller) achieves automatic lens clamping and active rotation driven by a rotary motor. A chamfering mechanism supported by a support frame (the chamfering frame angle is adjustable, and a chamfering cylinder drives the chamfering seat, which in turn drives the chamfering wheel driven by the chamfering motor) precisely chamfers the rotating lens edge. A pressure plate on a pressure frame provides stable downward pressure under the action of springs to prevent lens displacement. A control box enables automated control. The overall structure is compact and highly coordinated, achieving efficient, stable, and automated lens edge chamfering, making it particularly suitable for mass production. The design of the rotating sleeve and adjusting bolts provides flexibility in the chamfering angle, while the anti-slip strips and active drive design of the drive rollers ensure reliable lens rotation.

[0004] In a first aspect, this utility model provides an automated lens edge chamfering and grinding device, specifically comprising: a grinding table; a turntable rotatably mounted on the upper center of the grinding table via a rotating shaft; clamping frames fixedly mounted on the grinding tables on the left and right sides of the turntable, each clamping frame having a clamping mechanism for clamping a lens placed on the turntable; a support frame fixedly mounted on the grinding table on the other side between the two clamping frames near the edge; a chamfering frame mounted on the support frame, the chamfering frame having a chamfering mechanism for chamfering the lens rim; a pressure frame also vertically and horizontally positioned above the lens on the upper end of the support frame; and a control box fixedly mounted on the grinding table on one side of the support frame.

[0005] Optionally, the clamping mechanism includes a clamping cylinder, a clamping seat, a clamping roller, a drive roller, a rotary motor, and guide rods.

Vertical clamping rollers and drive rollers are rotatably installed at both ends of the clamping seat. The roller wall of the drive roller is provided with anti-slip strips. A rotary motor is provided at the upper end of the drive roller. The rotary motor drives the drive roller to rotate. Guide rods are vertically provided at the upper and lower ends of the clamping seat. The ends of the guide rods slide vertically through the clamping frame. The lens on the turntable is easily clamped and rotated by the clamping rollers and drive rollers on both sides.

[0006] Optionally, a columnar rotating sleeve is vertically fixed on one side of the upper end of the support frame, the rotating sleeve extends through the left and right sides, and an adjusting bolt is vertically screwed onto the rotating sleeve.

[0007] Optionally, the end of the pressure frame is provided with a pressure rod that rotates vertically, and the lower end of the pressure rod is fixedly connected to a pressure plate.

[0008] Optionally, the chamfering mechanism includes a chamfering cylinder, a chamfering seat, a chamfering wheel, a chamfering motor, and a hanging shaft; a hanging shaft is vertically provided on the middle of one side of the chamfering frame, the hanging shaft is inserted into the rotating sleeve and fixed by adjusting bolts, the chamfering cylinder is vertically fixedly installed on the upper end of the chamfering frame, an L-shaped chamfering seat is fixedly connected to the end of the piston rod of the chamfering cylinder, one side of the chamfering seat is slidably tangent to the chamfering frame, a chamfering wheel is rotatably installed on the chamfering seat, a chamfering motor is provided at one end of the chamfering wheel to drive its rotation, and the chamfering wheel is in contact with the edge of the lens.

[0009] This utility model provides an automated lens edge chamfering and grinding device, which has the following beneficial effects:

[0010] First, the clamping mechanism uses a clamping cylinder to drive the clamping seat to move horizontally, causing the clamping rollers and drive rollers to work together to clamp the lens edge. The drive rollers are directly driven by a rotary motor, and their anti-slip strip design greatly enhances the friction with the lens edge, ensuring stable rotation of the lens and effectively solving the problem of slippage or damage to the lens surface caused by traditional clamps. Simultaneously, the introduction of guide rods ensures the smoothness and precision of the clamping seat movement, further improving the stability of clamping and rotation. Second, the chamfering mechanism, through the cooperation of the hanging shaft and rotating sleeve, combined with the locking of the adjusting bolts, allows for flexible adjustment of the angle of the chamfering frame and chamfering wheels. This design allows operators to quickly and accurately set the required chamfering angle, significantly improving the equipment's adaptability and processing flexibility to different lens chamfering needs, eliminating the need for frequent tooling changes. Third, the pressure frame and its pressure plate, under the action of spring force, work in conjunction with the turntable to apply stable vertical pressure to the central area of ​​the lens, effectively suppressing axial runout or radial displacement that may occur during high-speed rotation and chamfering grinding, providing a solid guarantee for high-precision chamfering. Finally, the control box integrates the control of all actuators (clamping cylinder, rotary motor, chamfering cylinder, and chamfering motor), realizing fully automated operation from lens placement, automatic clamping and rotation, center pressing to chamfering feed and grinding. In summary, this device not only significantly improves the production efficiency and processing accuracy of lens chamfering, ensuring product consistency, but also effectively protects the lens surface and reduces the scrap rate through reliable clamping, flexible angle adjustment, and a stable pressing mechanism. It is easy to operate and significantly improves production efficiency, making it particularly suitable for mass production of precision optical lenses. Attached Figure Description

[0027] The clamping mechanism includes a clamping cylinder 201, a clamping seat 202, a clamping roller 203, a drive roller 204, a rotary motor 205, and a guide rod 206. The clamping cylinder 201 is vertically installed at the upper end of the clamping frame 2. The piston rod of the clamping cylinder 201 is vertically fixed to the clamping seat 202. The clamping seat 202 has vertically mounted vertical clamping roller 203 and drive roller 204 at its two ends. The drive roller 204 has anti-slip strips on its roller wall. The upper end of the drive roller 204 has a rotary motor 205, which drives the drive roller 204 to rotate. The upper and lower ends of the clamping seat 202 are vertically mounted with guide rods 206. The ends of the guide rods 206 slide vertically through the clamping frame 2. The lens on the turntable 101 is easily clamped and rotated by the clamping rollers 203 and drive roller 204 on both sides.

[0028] Among them, a columnar rotating sleeve 401 is vertically fixed on one side of the upper end of the support frame 4. The rotating sleeve 401 extends through the left and right sides, and an adjusting bolt 402 is vertically screwed onto the rotating sleeve 401.

[0029] The end of the pressure frame 5 is vertically rotatably equipped with a pressure rod 501. The lower end of the pressure rod 501 is fixedly connected to a pressure plate 502. The pressure plate 502 is vertically opposite to the turntable 101. The upper end of the pressure rod 501 is vertically equipped with a lifting rod 504 for easy upward lifting. A spring 503 is fitted on the pressure rod 501 between the pressure frame 5 and the pressure plate 502. The bottom of the pressure plate 502 abuts against the upper end of the lens.

[0030] In Embodiment 2, based on Embodiment 1, the chamfering mechanism includes a chamfering cylinder 601, a chamfering seat 602, a chamfering wheel 603, a chamfering motor 604, and a hanging shaft 605. A hanging shaft 605 is vertically mounted on the middle of one side of the chamfering frame 6. The hanging shaft 605 is inserted into the rotating sleeve 401 and secured by adjusting bolts 402. The chamfering cylinder 601 is vertically fixedly mounted on the upper end of the chamfering frame 6. An L-shaped chamfering seat 602 is fixedly connected to the end of the piston rod of the chamfering cylinder 601. One side of the chamfering seat 602 is slidably tangent to the chamfering frame 6. A chamfering wheel 603 is rotatably mounted on the chamfering seat 602. A chamfering motor 604 is provided at one end of the chamfering wheel 603 to drive its rotation. The chamfering wheel 603 contacts the edge of the lens.

[0031] The following provides further explanation and description of the functions and effects of each structure mentioned above, to help those skilled in the art better understand the technical solution:

[0032] A turntable 101 located in the center of the grinding table 1 is rotatable via a pivot, providing a basic platform for supporting and positioning the lens. Clamping frames 2 are symmetrically fixed on both sides of the turntable 101, and the clamping mechanism mounted on them is crucial for fixing and driving the lens. This clamping mechanism consists of a clamping cylinder 201, a clamping seat 202, a clamping roller 203, a drive roller 204, a rotary motor 205, and a guide rod 206. The clamping cylinder 201 is vertically mounted on the upper end of the clamping frame 2, and its piston rod drives the clamping seat 202 to move horizontally. Vertical clamping rollers 203 and drive rollers 204 are rotatably mounted at both ends of the clamping seat 202. The drive roller 204 has anti-slip strips on its surface and is driven to rotate by the rotary motor 205 at its top. The guide rods 206 at the upper and lower ends of the clamping seat 202 pass through the clamping frame 2 to ensure smooth horizontal movement. During operation, the clamping cylinder 201 drives the clamping seat 202 to move inward, so that the clamping rollers 203 and the drive rollers 204 on both sides clamp the edge of the lens placed on the turntable 101. The rotary motor 205 drives the lens to rotate stably on the turntable 101 through the drive rollers 204, preparing for subsequent chamfering.

[0033] On the other side of the turntable 101 (i.e., the opposite side between the two clamping frames 2), a support frame 4 is fixed near the edge of the grinding table 1. This support frame carries the chamfering mechanism and the clamping mechanism. A columnar rotating sleeve 401 is fixed to one side of the upper end of the support frame 4, and the rotating sleeve 401 extends through the left and right sides. The chamfering frame 6 is inserted into the rotating sleeve 401 through a hanging shaft 605 provided on it, and is secured by adjusting bolts 402 vertically screwed onto the rotating sleeve 401. This design allows the chamfering frame 6 and the chamfering mechanism on it to be angled around the axis of the hanging shaft 605, and locked by adjusting bolts 402, thereby flexibly adapting to the chamfering angle requirements of different lens edges. The chamfering mechanism specifically includes a chamfering cylinder 601, a chamfering seat 602, a chamfering wheel 603, a chamfering motor 604, and a hanging shaft 605. The chamfering cylinder 601 is vertically fixed to the upper end of the chamfering frame 6, and its piston rod drives the L-shaped chamfering seat 602 to move. One side of the chamfering seat 602 slides in contact with the chamfering bracket 6 to ensure movement stability. A chamfering wheel 603 is mounted on the chamfering seat 602 and is driven to rotate at high speed by the chamfering motor 604. When the lens is clamped and rotated, the chamfering cylinder 601 drives the chamfering seat 602 and the chamfering wheel 603 to feed towards the edge of the lens. The high-speed rotating chamfering wheel 603 contacts the rotating edge of the lens, completing the chamfering and grinding operation.

[0034] In addition, a pressure frame 5 is vertically mounted on the upper end of the support frame 4, pointing upwards towards the lens. A pressure rod 501 is rotatably mounted at the end of the pressure frame 5. A pressure plate 502 is fixed at the lower end of the pressure rod 501, and a lifting rod 504 is provided at the upper end. A spring 503 is fitted on the pressure rod 501, located between the pressure frame 5 and the pressure plate 502. The pressure plate 502 is vertically opposite to the turntable 101. After the lens is placed, the pressure plate 502, under the elastic force of the spring 503, presses down on the center area of ​​the upper surface of the lens through the pressure rod 501. Working together with the turntable 101 below, it effectively prevents the lens from jumping or shifting during high-speed rotation and chamfering, ensuring clamping stability and chamfering accuracy. Finally, the control box 3 fixed on the grinding table 1 on one side of the support frame 4 serves as the control core of the device, coordinating and controlling the actions of the clamping cylinder 201, rotary motor 205, chamfering cylinder 601, chamfering motor 604, and other actuators to achieve automated operation of the entire chamfering and grinding process.

[0035] Working Principle: The operator first places the lens to be chamfered on the turntable 101 in the center of the grinding table 1. Then, the device is activated via the control box 3. The clamping mechanism begins to operate, specifically by the action of the clamping cylinders 201 mounted on the upper ends of the left and right clamping frames 2. Their piston rods drive the clamping seats 202 to move horizontally towards the lens. The movement of the clamping seats 202 is guided by guide rods 206 at both ends, ensuring smooth and precise movement. Simultaneously, the clamping rollers 203 and drive rollers 204 at both ends of the clamping seats 202 move inward, clamping the lens edges from both sides. At this time, the rotary motor 205 at the upper end of the drive roller 204 starts, driving the drive roller 204, which has anti-slip strips on its surface, to rotate. Under the action of friction, the drive roller 204 drives the lens and drives the driven clamping roller 203, causing the lens to rotate stably around its central axis on the turntable 101.

[0036] As the lens is clamped and rotated, the pressure frame 5 located at the upper end of the support frame 4 begins to function. The operator can lift the pressure rod 501 upwards using the lifting rod 504, causing the pressure plate 502 to rise and clear space for the lens. After the lens is placed, the lifting rod 504 is released, and the pressure plate 502, under the elastic force of the spring 503 fitted onto the pressure rod 501, presses downwards against the center area of ​​the upper surface of the lens. The pressure plate 502, together with the turntable 101 below, forms a vertical limit on the lens, effectively preventing axial runout or radial displacement of the lens during high-speed rotation and subsequent chamfering and grinding, ensuring a stable lens position and providing a foundation for high-precision chamfering.

[0037] Next, the chamfering mechanism performs the chamfering operation. The chamfering frame 6 is inserted into the rotating sleeve 401 at the upper end of the support frame 4 via its hanging shaft 605, and can rotate around the axis of the hanging shaft 605. By tightening the adjusting bolt 402 on the rotating sleeve 401, the chamfering frame 6 and the chamfering mechanism on it can be locked at the required angle position to adapt to the processing requirements of different chamfering angles. The chamfering motor 604 starts, driving the chamfering wheel 603 to rotate at high speed. The chamfering cylinder 601 is activated, and its piston rod pushes the L-shaped chamfering seat 602, causing the chamfering seat 602 to slide along the chamfering frame 6 (tangential contact ensures stable guidance), thereby driving the high-speed rotating chamfering wheel 603 to feed radially towards the edge of the rotating lens. When the chamfering wheel 603 contacts the edge of the lens, the chamfering and grinding of the lens's circumference begins. The chamfering cylinder 601 can precisely control the feed depth and pressure of the chamfering wheel 603 to ensure the consistency and quality of the chamfering.
