Description

Technical Field

[0001] This invention relates to the field of optical element processing technology, and more specifically to a manufacturing apparatus for processing various diameters, focal lengths, and condenser lenses. Background Technology

[0002] Condensing lens processing equipment is a key piece of equipment in the field of optical manufacturing, mainly used in solar energy utilization, laser technology, and optical instruments. Its core function is to achieve the preset diameter and focal length parameters of the lens through precise cutting, thereby realizing the efficient focusing of light. In the solar energy field, condensing lenses need to focus light at a single point to generate high temperatures to meet energy conversion requirements. The core requirements of this type of equipment are to be adaptable to the processing of lenses of different specifications, ensure processing accuracy and efficiency, and at the same time reduce damage to the workpiece.

[0003] Existing condenser lens processing equipment suffers from several significant drawbacks: First, it lacks versatility, being primarily single-specification equipment. Processing lenses of different diameters and focal lengths requires separate molds and processing devices, resulting in high equipment investment costs and large space requirements. Second, processing efficiency is low, with cumbersome mold design, manufacturing, and replacement processes leading to lengthy production cycles and difficulty in responding to small-batch, multi-specification processing needs. Third, the workpiece clamping method is unreasonable; traditional mechanical clamping easily damages the lens surface, affecting product quality. Fourth, processing accuracy is insufficient; the drive mechanism lacks stable braking function, and inertial impact during shutdown can easily cause component deviations. Furthermore, the lack of a collaborative control mechanism makes it difficult to ensure the synchronization of multi-tool processing. Fifth, operation is complex, requiring manual adjustment of processing parameters and paths, relying on specialized technicians, and exhibiting a low fault tolerance rate.

[0004] Therefore, there is an urgent need to design a special processing equipment for condenser lenses that is versatile, efficient, non-destructive in clamping, stable in precision, and easy to operate. Through an integrated structure and coordinated control, it is necessary to solve many of the pain points of existing equipment and promote the large-scale application of condenser lenses in related fields.

Each set of three-axis machining devices is equipped with a rotary tool holder and at least two diamond tools at its end. The three-axis machining devices can realize the X, Y, and Z axis movement and rotation control of the diamond tools. Through the coordinated action of the two sets of three-axis machining devices, multiple diamond tools can be operated simultaneously for cutting.

[0011] The collaborative control system includes a control station, which is connected to the hydraulic motor, counter, negative pressure vacuum pump station and three-axis machining device, and can generate an automatic machining control program based on the input lens parameters.

[0012] Preferably, the hydraulic motor is connected to an external hydraulic station via a hydraulic pipeline, and the hydraulic pipeline is equipped with a flow regulating valve to achieve stepless speed regulation of the rotating gear bearing. Furthermore, the hydraulic motor has a braking structure, so there is no inertial impact when it stops.

[0013] Preferably, the surface of the pinhole dense array platform is uniformly distributed with adsorption holes, and a sealing gasket is provided at the connection between the vacuum rotating gas ring and the gas distribution plate.

[0014] Preferably, the rotary gear bearing also meshes with a rotation transmission gear, which is linked to a counter. The counter cooperates with the rotation transmission gear to detect the real-time rotation of the rotary gear bearing.

[0015] Preferably, the diamond tool has a cutting edge structure with different radii of curvature to adapt to the processing requirements of lenses with different focal lengths.

[0016] Preferably, the control station of the collaborative control system has a built-in lens processing control program generation module, which supports importing lens CAD drawings and allows manual input of lens diameter and focal length parameters, and automatic planning of processing paths.

[0036] Please see the appendix Figure 1-6 This invention discloses a manufacturing apparatus for processing various diameters, focal lengths, and condenser lenses. In the basic support assembly, the chassis 1 is located at the bottom of the equipment, the support frames 2 are symmetrically distributed on both sides of the chassis 1 and vertically fixed, and the upper crossbeam 3 is horizontally mounted on top of the two sets of support frames 2, forming a gantry frame. The rotary drive mechanism is installed in the middle area of ​​the chassis 1, between the two sets of support frames 2. The pinhole dense array platform of the negative pressure clamping mechanism is horizontally fixed on top of the rotary gear bearing 5, and the air distribution plate 10 is located inside the chassis 1, below the rotary gear bearing 5. The two sets of three-axis processing devices 4 of the dual three-axis processing assembly are symmetrically installed below the upper crossbeam 3, with the central axis of the crossbeam as the center of symmetry, facing the pinhole dense array platform. The control station of the collaborative control system is installed on the outside of the equipment and connected to each mechanism through lines.

[0037] The basic support assembly is an integrated gantry structure, with the chassis 1 being flat, the support frame 2 being columnar, and the upper crossbeam 3 being elongated. The rotary drive mechanism consists of a rotary gear bearing 5, a hydraulic motor 6, and a drive gear 7. The output end of the hydraulic motor 6 is fixed to the drive gear 7, and the drive gear 7 meshes with the external teeth of the rotary gear bearing 5. The negative pressure clamping mechanism includes a gas distribution plate 10, a negative pressure vacuum pump station, a pinhole dense array platform, and a vacuum rotating air ring. The surface of the pinhole dense array platform is distributed with dense adsorption holes. The vacuum rotating air ring is sleeved on the outside of the rotary gear bearing 5, with one end connected to the pinhole dense array platform and the other end connected to the gas distribution plate 10. The dual three-axis machining assembly contains two identical three-axis machining devices 4. Each device is equipped with a rotary tool holder 401 at its end, and at least two diamond tools 402 are fixed on the rotary tool holder 401. The three-axis machining device 4 has built-in transverse, downward, and rotary drive structures. The core of the collaborative control system is a control station with a built-in program generation module and a signal transmission interface.

[0038] The basic support components provide stable support for each mechanism, ensuring the rigidity of the equipment during processing. After the hydraulic motor 6 starts, it drives the drive gear 7 to rotate. The drive gear 7 meshes with the rotating gear bearing 5 to make it rotate, which in turn drives the workpiece on the pinhole array platform to rotate synchronously. The negative pressure vacuum pump station generates negative pressure, which is transmitted to the pinhole array platform through the air distribution plate 10 and the vacuum rotating air ring to adsorb and fix the workpiece. The control station generates a processing program according to the input parameters and controls the two sets of three-axis processing devices 4 to work together. By adjusting the position through horizontal and downward movement, the rotating tool holder 401 drives the diamond tool 402 to rotate, and performs synchronous cutting processing on the rotating workpiece.

[0039] To further optimize the above technical solution, one end of the hydraulic pipeline is connected to an external hydraulic station, and the other end is connected to the hydraulic motor 6. The entire pipeline is arranged along the inner side of the chassis 1 and the support frame 2 to avoid interfering with other mechanisms. The flow regulating valve is connected in series on the hydraulic pipeline and is located near the input end of the hydraulic motor 6. The hydraulic motor 6 is fixed inside the chassis 1 and is located on one side of the rotating gear bearing 5.

[0040] The hydraulic pipeline is a high-pressure flexible pipe with a smooth inner wall and an outer protective layer; the flow regulating valve is a valve body structure with a built-in valve core, equipped with an adjustment knob and a signal receiving module; the hydraulic motor 6 is a braking structure with a built-in brake piston and spring assembly, and the output end is equipped with a connecting flange and a drive gear 7 for fixation.

[0041] When in use, the external hydraulic station outputs hydraulic oil, which is then transported to the hydraulic motor 6 via hydraulic pipelines. The control station sends a speed signal to the flow regulating valve, and the valve core adjusts the opening to change the hydraulic oil flow, thereby regulating the output speed of the hydraulic motor 6 and realizing stepless speed change of the rotating gear bearing 5. When stopping, the control station sends a braking signal, and the built-in brake piston of the hydraulic motor 6 resets under the action of the spring, locking the output shaft to avoid inertial impact.

[0042] To further optimize the above technical solution, the adsorption holes are evenly distributed on the upper surface of the pinhole array platform and penetrate the upper and lower parts of the platform; the sealing gasket is installed on the mating end face of the vacuum rotating gas ring and the gas distribution plate 10, and is located in the gap between the two.

[0043] The adsorption holes are circular through holes with a uniform diameter and a distribution density of 5-8 holes per square centimeter. The sealing gasket is an annular structure with its inner diameter matching the outer diameter of the vacuum rotating gas ring output end and its outer diameter matching the inner diameter of the gas distribution plate 10 input end. Its surface is smooth and burr-free. After the negative pressure vacuum pump station is started, a negative pressure is formed within the adsorption holes on the pinhole array platform. Atmospheric pressure is used to firmly press the workpiece onto the platform surface. The sealing gasket fills the gap between the vacuum rotating gas ring and the gas distribution plate 10 to prevent negative pressure leakage, ensuring stable negative pressure within the adsorption holes and guaranteeing secure workpiece clamping.

[0044] To further optimize the above technical solution, the rotation transmission gear 8 is installed inside the chassis 1 and meshes with the external teeth of the rotary gear bearing 5, located on one side of the drive gear 7; the counter 9 is fixed to the inner side wall of the chassis 1, and its detection end is opposite to the edge of the rotation transmission gear 8.

[0045] The rotation speed transmission gear 8 is a circular gear with a number of teeth that matches the external teeth of the rotating gear bearing 5, and a mounting shaft is provided at the center; the counter 9 is a contact or non-contact sensor with a built-in signal conversion module and transmission interface, and a sensing element is provided at the detection end.

[0046] When the rotary gear bearing 5 rotates, it drives the meshing rotation transmission gear 8 to rotate synchronously; the counter 9 senses the number of rotations of the rotation transmission gear 8 at the detection end, converts the mechanical rotation signal into an electrical signal, and transmits it to the control station through the line; the control station calculates the real-time rotation speed of the rotary gear bearing 5 based on the rotation signal, compares it with the preset speed, and if there is a deviation, it automatically adjusts the flow regulating valve to correct it.

[0047] To further optimize the above technical solution, the dual three-axis machining assembly is fixed to the lower surface of the upper crossbeam 3 by two independent mounting seats. The mounting seats are arranged in a mirror image with the central axis of the upper crossbeam 3 as the center. The center line connecting the two sets of three-axis machining devices 4 is perpendicular to the central axis of the upper crossbeam 3 and is directly opposite the central area of ​​the lower aperture array platform, ensuring that the cutting range completely covers lens workpieces of different diameters.

[0048] The mounting base is connected to the upper crossbeam 3 via a T-slot and a locking bolt. The spacing between the two sets of three-axis machining devices 4 can be finely adjusted along the length of the upper crossbeam 3 to accommodate the machining needs of lenses of different sizes. After adjustment, it is fixed by the locking bolt to ensure that the position is stable and without deviation during the machining process.

[0049] Each three-axis machining unit 4 is an independent modular structure, capable of three-way movement: transverse (X-axis), downward (Z-axis), and tool rotation (C-axis). Specifically, it includes the following components:

[0050] The X-axis drive and guiding mechanism uses a high-precision servo motor, connected to a ball screw via a flexible coupling. The servo motor has a built-in encoder, which connects to the control station signal to achieve closed-loop position control. It is equipped with two parallel linear guides, which are fixed to the upper crossbeam 3 mounting base. The slider is connected to the Y-axis mounting plate. The linear guides adopt a ball bearing structure, which has low motion resistance and high positioning accuracy.

[0051] The Y-axis drive and guide mechanism are integrated on the Y-axis mounting plate of the X-axis slider. The movement direction is perpendicular to the X-axis and arranged horizontally, used for fine-tuning the cutting position of the tool in the radial direction of the lens. It also employs a servo motor and ball screw drive system, coupled with a single high-precision linear guide rail to ensure positional synchronization during multi-tool cutting.

[0052] The Z-axis drive and guide mechanism are mounted perpendicularly to the side of the Y-axis moving plate, with the movement direction perpendicular to both the X and Y axes, enabling the tool to move up and down and adjust the cutting depth. The drive end is a servo motor with braking function, connected to a ball screw via a planetary reducer to increase the output torque; the guide structure consists of two sets of parallel linear guides, with the slider fixed to the rotary tool holder mounting base.

[0053] The rotary tool holder 401 is fixed to the lower end of the Z-axis slider and has an overall cylindrical structure with its axis coinciding with the Z-axis, allowing for continuous 360° rotation. It incorporates a built-in high-frequency spindle motor, whose output shaft is connected to the rotary tool holder 401 via a spline, meeting the cutting requirements of lenses made of different materials.

[0054] Multiple diamond cutting tools 402 are evenly distributed and fixed around the circumference of the rotating tool holder 401, with the cutting edges facing the pinhole array platform, and the tools with different curvatures are arranged at intervals.

[0055] The diamond tool 402 consists of a cutting edge and a tool holder. The cutting edge has an arc-shaped structure, and the radius of curvature of the cutting edge varies for different tools. The tool holder is cylindrical and is adapted to the mounting hole of the rotating tool holder 401, and is fixed by a locking screw.

[0056] To further optimize the above technical solution, the control station is installed on the outside of the equipment in a convenient location for operation. It is connected to the hydraulic motor 6, counter 9, negative pressure vacuum pump station and three-axis machining device 4 via signal lines, with the lines fixedly arranged along the equipment frame.

[0057] The control station includes an operation panel, a main unit, and signal interfaces. The operation panel is equipped with a display screen, parameter input buttons, and function buttons. The main unit has a built-in lens processing control program generation module, a central processing unit, and a storage unit. The signal interfaces include digital signal interfaces and analog signal interfaces to adapt to the signal transmission needs of different organizations.

[0058] Operators input lens diameter and focal length parameters or import CAD drawings through the operation panel; the program generation module reads the parameters or drawing data, combines the equipment's motion range and diamond tool 402 parameters, and automatically plans the transverse path, downward depth, rotational speed and rotational speed of the three-axis machining device 4 to generate a standardized machining program; the central processing unit converts the program instructions into control signals, which are sent to each actuator through signal lines to control their coordinated operation.

[0059] How to use

[0060] 1. Parameter setting and program generation: The operator inputs the diameter and focal length parameters of the condenser lens to be processed into the control station and imports the corresponding 3D drawing of the condenser lens. The control program generation module automatically plans the X-axis transverse path, Z-axis downward depth and rotation speed of the rotary tool holder 401 of the three-axis machining device 4 according to the surface curvature requirements of the lens, and sets the rotation speed of the rotary drive mechanism at the same time.

[0061] 2. Workpiece clamping: Place the lens blank workpiece (such as glass or optical resin material) at the center of the pinhole array platform. Start the negative pressure vacuum pump station through the control station. The gas distribution plate 10 delivers negative pressure to the pinhole array platform through the vacuum rotating gas ring. The negative pressure generated by the adsorption hole firmly fixes the blank workpiece, completing the clamping. If the workpiece has a special shape, a mechanical clamping pressure plate device needs to be installed at the same time for auxiliary fixation.

[0062] 3. Machining Operation: The control station sends a machining start signal, activating the hydraulic motor 6. This motor drives the rotary gear bearing 5 and the workpiece on the pinhole array platform to rotate at a constant speed via the drive gear 7. Simultaneously, two sets of three-axis machining devices 4 start according to a preset program. The X-axis servo motor drives the machining device to move laterally to the machining start position, while the Z-axis servo motor drives the rotary tool holder 401 to descend to the cutting depth. The rotary tool holder 401 drives the diamond tool 402 to rotate at high speed, performing cutting on the workpiece surface. During machining, the counter 9 monitors the rotation speed of the rotary gear bearing 5 in real time and feeds the signal back to the control station. The control station adjusts the lateral and descent speeds of the three-axis machining devices 4 based on the rotation speed signal to ensure the cutting accuracy of the workpiece surface and to ensure that the refracted light from every point on the lens surface converges to the preset focal point.

[0063] 4. Finished product removal: After processing is completed, the control station sends a stop signal, the hydraulic motor 6 brakes and stops rotating, the three-axis processing device 4 resets to the initial position, the negative pressure vacuum pump station stops working, the negative pressure of the pinhole dense array platform disappears, and the operator can remove the finished condenser lens.
