Description

Technical Field

[0001] This invention relates to the field of optical lens manufacturing equipment technology, and in particular to a large lens rapid flipping device. Background Technology

[0002] As modern optical systems demand increasingly higher imaging quality, the need for large-aperture aspherical optical elements is growing. The increased aperture of the lenses leads to a rapid increase in lens weight. Based on the potential need for lightweight optical systems, processing is required on both surfaces of the lens, necessitating lens flipping.

[0003] Currently, lens flipping is mostly done manually. When the diameter is too large, auxiliary equipment is also used to assist in lens flipping. There is a risk that the lens may fall off or be damaged during the flipping process due to improper clamping. In addition, flipping large lenses requires more manpower.

[0004] Chinese patent application document CN222818870U, published on May 2, 2025, discloses a flip-over frame for radar signal debugging, including a movable box. A support frame is fixedly connected to the upper surface of the movable box. Two connecting shafts are rotatably connected inside the support frame. The ends of the two connecting shafts that are close to each other are fixedly connected to a fixed seat. A servo motor is fixedly connected to the front of the support frame. The power output end of the servo motor passes through the support frame and is fixedly connected to the end of the connecting shaft that is close to the servo motor. A bidirectional screw is rotatably connected inside the fixed seat. Two moving blocks are threadedly connected to the outer surface of the bidirectional screw. A snap-fit ​​bracket is fixedly connected to the left side of each moving block. Five placement racks are slidably connected inside the movable box. A circular groove is opened on the inner bottom wall of each placement rack.

[0005] The radar signal tuning flipping frame disclosed in this patent application uses a bidirectional screw and a threaded connection between the moving block to move the locking brackets closer or further apart, thus enabling lens replacement and fixation. Simultaneously, a servo motor, in conjunction with a support frame and connecting shaft, adjusts the elevation angle of the fixed base to ensure the normal operation of the lens flipping. However, for large lenses, the flipping efficiency and stability are unsatisfactory. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, the present invention provides a large lens rapid flipping device. The present invention achieves rapid and stable flipping of large lenses through a motor-driven support frame and support rod structure, which significantly improves operating efficiency and safety.

[0007] This invention is achieved through the following technical solution: A large lens rapid flipping device includes a base, characterized in that: a flipping frame is provided on the base, the flipping frame includes a support frame, a support body, and a fixing beam for fixing the lens, the support frame is fixed on the base, the support body and the support frame are connected by a shaft system, the support frame is provided with a drive motor for driving the support body to flip, the fixing beam is fixed on the support body, the fixing beam has an oblong hole, a support rod is provided through the oblong hole, the support rod includes a support screw, an adjusting nut and a support block, the support block has a groove, the front end of the support screw is provided with a spherical head that matches the groove of the support block, and the support screw is connected to the fixing beam by the adjusting nut.

[0008] The base includes a bracket, a connecting rod, swivel casters, and swivel feet. The connecting rod is fixed to the bottom wall of the bracket, the swivel casters are installed at the four corners of the bracket, and the swivel feet are installed on the connecting rod.

[0009] The support frame is provided with a support steel strip for auxiliary support of the lens.

[0010] The top of the support frame has a first through hole and a second through hole. One end of the support steel strip passes through the first through hole and is slidably connected to the support frame. The other end of the support steel strip passes through the second through hole and is slidably connected to the support frame.

[0011] The fixed crossbeams consist of two sets, which are arranged in a cross shape on the support frame.

[0012] The shaft system consists of two roller bearings, one of which is mounted on one side of the support frame and the other on the other side of the support frame, with the two roller bearings corresponding to each other.

[0013] The support block of the support rod is made of polyurethane or nylon material.

[0014] The support frame is also equipped with a photoelectric encoder for detecting the rotation angle of the support frame.

[0015] A flexible protective layer is bonded to the surface of the supporting steel strip.

[0016] Of the two sets of fixed crossbeams arranged in a cross shape, one set of fixed crossbeams has a long, narrow hole, while the other set of fixed crossbeams has an arc-shaped hole.

[0017] The beneficial effects of this invention are mainly reflected in the following aspects: 1. This invention provides a flipping frame mounted on a base. The flipping frame includes a support frame, a support body, and a fixing beam for fixing lenses. The support frame is fixed to the base, and the support body is connected to the support frame via a shaft system. The support frame is equipped with a drive motor for driving the support body to flip. The fixing beam is fixed to the support body and has an oblong hole. A support rod passes through the oblong hole. The support rod includes a support screw, an adjusting nut, and a support block. The support block has a groove, and the front end of the support screw has a spherical head that matches the groove of the support block. The support screw is connected to the fixing beam via the adjusting nut. As a complete technical solution, compared with the prior art, the motor-driven support frame and support rod structure enables rapid and stable flipping of large lenses, significantly improving operational efficiency and safety. 2. In this invention, the base includes a bracket, a connecting rod, swivel casters, and swivel feet. The connecting rod is fixed to the bottom wall of the bracket, the swivel casters are installed at the four corners of the bracket, and the swivel feet are installed on the connecting rod. The swivel casters and swivel feet make the device easy to move and fix, improving the flexibility and site adaptability of the equipment. The structure of the connecting rod enhances the stability and load-bearing capacity of the base, ensuring that it will not move accidentally during the flipping process, thus improving safety.

[0018] 3. In this invention, the support frame is provided with a support steel strip for auxiliary support of the lens. The support steel strip provides additional auxiliary support to prevent the large lens from shaking or deforming during the flipping process, reducing the risk of damage and increasing the safety and reliability of the flipping device.

[0019] 4. In this invention, the top of the support frame has a first through hole and a second through hole. One end of the support steel strip passes through the first through hole and is slidably connected to the support frame. The other end of the support steel strip passes through the second through hole and is slidably connected to the support frame. Through the through holes and the sliding connection, the position of the support steel strip can be flexibly adjusted to adapt to large lenses of different shapes and sizes. This installation method makes the support more uniform and improves the support effect.

[0020] 5. In this invention, there are two sets of fixed crossbeams, which are arranged in a cross shape on the support frame. The cross-shaped arrangement of the fixed crossbeams provides uniform support force, which can reduce stress concentration caused by uneven force on large lenses. This specific layout ensures the balance and stability of large lenses during the flipping process.

[0021] 6. In this invention, the shaft system consists of two roller bearings. One roller bearing is installed on one side of the support frame, and the other roller bearing is installed on the other side of the support frame. The two roller bearings correspond to each other, which reduces friction, makes the rotation of the support frame smoother, and reduces energy consumption and wear. The corresponding arrangement of the two roller bearings ensures rotational balance and improves the durability and reliability of the rotation device.

[0022] 7. In this invention, the support block of the support rod is made of polyurethane or nylon material. The support block is made of polyurethane or nylon material, which is soft and wear-resistant, effectively preventing scratches on the surface of large lenses. It also has good cushioning performance, reducing the impact of impact on large lenses and improving the protection effect.

[0023] 8. In this invention, the support frame is also provided with a photoelectric encoder for detecting the flip angle of the support frame. The photoelectric encoder accurately detects the flip angle, realizes precise control and positioning, improves the operation accuracy, helps with automated operation, ensures the repeatability of the flip angle, and improves the automation level of the flipping device.

[0024] 9. In this invention, a flexible protective layer is bonded to the surface of the supporting steel strip. The flexible protective layer on the supporting steel strip further buffers the contact force, prevents hard objects from directly contacting the surface of the large lens, prevents scratches, and extends the service life of the large lens.

[0025] 10. In this invention, among the two sets of fixed crossbeams arranged in a cross shape, one set of fixed crossbeams has a long, narrow waist-shaped hole, while the other set of fixed crossbeams has an arc-shaped waist-shaped hole. The long, narrow, and arc-shaped waist-shaped holes allow the support rod to be adjusted in multiple directions, adapting to the curvature and shape changes of large lenses, providing greater flexibility, and ensuring that large lenses are firmly fixed and subjected to uniform force.

Then, the steel strip nut on the support steel strip 19 is adjusted to tighten the support steel strip 19.

[0069] When the large lens 24 is flipped, the electronic lock is released, and the host computer sends a flipping command. After receiving the command, the drive motor 7 starts to drive the support frame 4 to flip. After reaching the designated flipping position, the position information is fed back and the current position is fixed. When unloading the large lens 24, remove the fixed crossbeam 5, adjust the steel belt nut of the support steel belt 19, release the support steel belt 19, and use a hoisting tool to lift the large lens 24 out of the support frame 4 of the flipping device.

[0070] The large lens 24 is rapidly flipped using the flipping frame 2 and drive motor 7, improving operational efficiency and automation. The adjustable design of the support rod 9 allows for flexible adjustment of the position of the large lens 24, ensuring a secure fixation and adapting to large lenses 24 of different sizes, thus enhancing the versatility and stability of the flipping device.
