Description

Technical Field

[0001] This invention relates to the field of optical element processing equipment technology, and specifically to a high-precision aspherical optical element alignment and bonding device. Background Technology

[0002] Aspherical optical elements are widely used in precision optical instruments, imaging systems, and high-end manufacturing. During their processing, the lenses typically need to be fixed to a specialized fixture using adhesives such as paraffin wax before grinding or polishing to ensure the stability and precision of subsequent processing. The coaxiality of the lens's optical axis and the fixture's rotation axis directly affects the final processing quality; therefore, alignment and clamping are particularly critical.

[0003] In existing technologies, such operations largely rely on manual experience, involving operators manually adjusting the position of the lens and fixture before simply fixing it in place. This method is cumbersome and inefficient, making it difficult to meet production cycle requirements when dealing with batch processing. Furthermore, manual adjustment struggles to achieve high-precision control, easily leading to eccentricity errors between the lens and fixture, affecting subsequent processing accuracy. In addition, while some existing equipment incorporates mechanical positioning structures, it often uses fixed tooling or single-direction adjustment methods, resulting in limited adjustment accuracy and a lack of effective coordination in correcting multi-directional deviations, leading to significant error accumulation.

[0004] Meanwhile, existing devices generally lack real-time detection and closed-loop feedback mechanisms, making it impossible to dynamically acquire lens position data and automatically correct it during adjustment. This results in poor stability and difficulty in guaranteeing repeatability during the positioning process. In the fixing stage, most devices use manual coating or simple injection methods, making it difficult to accurately control the amount of adhesive used. This can easily lead to problems such as excess adhesive or insufficient adhesive, thus affecting the reliability of clamping. Furthermore, existing devices have poor adaptability to lenses of different sizes, usually requiring the replacement of fixtures or readjustment of parameters, reducing the versatility of the equipment and increasing operational complexity.

[0005] Therefore, how to achieve high-precision automatic alignment between lenses and fixtures, improve clamping efficiency, enhance equipment versatility, and ensure the stability and reliability of the fixing process has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0011] Preferably, the operating component includes an regulator housing, a micro geared motor is fixedly mounted at the end of the regulator housing, the output end of the micro geared motor is connected to an adjusting shaft, the adjusting shaft is provided with a threaded head, the threaded head engages with the internal thread of a threaded sleeve, a connector is fixedly mounted at the end of the threaded sleeve, the middle section of the threaded sleeve is slidably connected to a guide cover, the guide cover is fixedly mounted inside the regulator housing, and has a non-circular guide groove in the middle that can slidably connect with the threaded sleeve, and an adjusting rod is fixedly mounted on the connector.

[0012] Preferably, the connector is equipped with a hose joint, which is connected to the nozzle on the adjusting rod through an internal channel. The nozzle is located on the lower side of the adjusting rod, biased towards the auxiliary adjusting mechanism. A hose is connected to the hose joint, and the upper end of the hose is connected to the output end of the active injector. The active injector is powered by an external motor, and the injection process of the active injector is precisely controlled by an external electromagnetic control valve. The single injection volume can be automatically adjusted according to the lens size to avoid the fixative overflow or insufficient injection affecting the clamping effect. Preferably, the hollow rotating platform is driven by teeth on the outside, which are connected to the drive device through a meshing worm gear, achieving low-speed precise adjustment and possessing self-locking capability.

[0013] Preferably, the drive systems of the auxiliary adjustment mechanism, the detection and curing mechanism, and the lens adjustment mechanism are all high-precision servo motors, which achieve position accuracy control at the 0.01mm level through pulse control; the operating component achieves precision transmission through the micro geared motor in conjunction with the threaded head and threaded sleeve, ensuring that the displacement resolution of the adjustment rod reaches 0.005mm.

The following description is provided to enable any person skilled in the art to make and use the invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0022] Reference Figure 1 - Figure 7 A high-precision aspherical optical element alignment and bonding device is integrally mounted on a support bracket 10. The support bracket 10 serves as the load-bearing foundation, and a hollow rotating platform 12 is fixedly mounted at the center of its upper end face. The hollow rotating platform 12 is rigidly connected to the support bracket through a high-strength connection method (such as bolts), thereby ensuring overall stability and providing a reliable foundation for subsequent high-precision adjustments. The hollow rotating platform 12 has a hollow cavity structure, in which a vertical lifting module is installed. The telescopic end of this module is connected to a suction cup, which reliably adsorbs the lens 16 to be processed through negative pressure. This combination structure of "hollow + lifting + adsorption" allows the lens to remain stable during rotation and to achieve active clamping and release in different processes. Compared with traditional mechanical clamping methods, it can avoid lens damage caused by stress concentration.

[0023] The hollow rotary platform 12 is equipped with teeth on its outer side and driven by a worm gear, achieving low-speed, high-precision rotation and a self-locking function. It maintains stable position without continuous power supply during adjustment, effectively improving the smoothness and anti-interference capability of the adjustment process. In actual operation, the lens to be processed 16 and the lens clamp 11 are stacked sequentially on the hollow rotary platform 12. By adjusting the angle of the rotary platform, deviations in any direction can be transformed into linear adjustment problems in a single direction, thus greatly simplifying the adjustment logic.

[0024] A detection and curing mechanism is installed on the equipment support 10 on one side of the hollow rotating platform 12. The mechanism is fixed by the detection bracket 14 and has a guide groove facing the platform. The detection seat 18 is slidably installed in the groove and is connected to the drive motor through the detection screw 17 to achieve precise lifting.

[0025] A laser rangefinder 19 is fixed on the detection base 18. When working, the laser rangefinder 19 scans the edge of the lens and feeds the distance signal back to the main board in real time. The center deviation of the lens is calculated by the algorithm. This closed-loop structure of "detection-feedback-calculation" can continuously correct the error. Compared with manual visual inspection or single-point detection, it significantly improves the positioning accuracy and repeatability.

[0026] A lens adjustment mechanism is installed on the opposite side of the curing and testing mechanism. It is fixed by an adjustment bracket 13 and also employs a slotted + screw drive, enabling precise radial movement of the operating component. The operating component internally consists of an adjuster housing 21, a micro-gear motor 24, an adjustment shaft 30, a threaded sleeve 28, and a guide cover 27, forming a precision transmission chain. The threaded engagement between the adjustment shaft 30 and the threaded sleeve 28 converts the motor rotation into micron-level linear displacement, while the guide cover 27 provides limiting guidance, ensuring stable and wobbly movement. This structure essentially corresponds to the "micro-motor + ball screw / push rod" described in the specifications, but through multi-stage guiding and deceleration design, the adjustment resolution reaches 0.005mm, thus enabling micron-level positioning.

[0027] The adjusting rod 25 is fixed to the front end of the connector 22. Its head is planarized, forming a surface contact when pushing the lens 16 or lens clamp 11. This structure effectively avoids slippage or tilting problems caused by point contact, making the adjustment process more stable and reliable. Meanwhile, the connector 22 has a fluid channel inside. One end of this channel is located on the hose connector 26, and the other end is connected to the nozzle 31 on the adjusting rod 25. The nozzle 31 is located on the lower side of the adjusting rod 25, close to the auxiliary adjusting mechanism. The hose connector 26 is connected to the active injector 29 via a hose 23, thus enabling the adjusting rod 25 to perform both mechanical pushing and adhesive delivery functions. Compared to the traditional split structure, this reduces mechanism switching time and improves the accuracy of the spray position.

[0028] The general working process is as follows: First, the lens to be processed 16 and the lens clamp 11 are placed sequentially on the hollow rotating platform 12. The detection and curing mechanism is activated, and the height of the laser rangefinder 19 is adjusted by the detection screw 17 to align it with the edge of the lens for scanning. The laser rangefinder 19 collects the distance data of the lens edge in real time and converts it into an electrical signal, which is transmitted to the main board for comparison and analysis. The main board calculates the deviation value between the current lens center and the theoretical center according to a preset algorithm, and sends the adjustment command to the micro reduction motor 24 in the lens adjustment mechanism and the rotation motor of the hollow rotating platform 12, driving the lens adjustment mechanism and the hollow rotating platform 12 to work together to gradually eliminate multi-directional errors. In this process, the angle change of the rotating platform and the linear advance of the adjustment rod work together to transform the complex two-dimensional deviation into a step-by-step linear correction, thereby improving the adjustment efficiency and accuracy.

[0029] After the lens 16 is positioned, the vertical lifting module drives the suction cup to adhere and fix it. Then, the detection and curing mechanism and the lens adjustment mechanism move upwards as a whole, performing the same detection and adjustment on the lens clamp 11 to ensure their centers are aligned. After positioning, the active injector 29 is activated, and liquid paraffin is delivered through the hose 23 to the connector 22. It is then sprayed through the nozzle 31 via the internal channel of the adjusting rod 25 and precisely injected into the contact area between the lens and the clamp. Simultaneously, the hollow rotating platform 12 slowly rotates, evenly distributing the adhesive to form a ring-shaped layer. During injection, the ultraviolet curing lamp 20 operates synchronously, accelerating the curing of the paraffin and improving connection efficiency and bonding strength.

[0030] The entire system adopts a modular power structure, with each drive motor independently controlled and communicating with the main board via a bus to achieve coordinated operation of detection, adjustment, rotation, injection, and lifting actions.

[0031] The laser rangefinder 19 scans the edge contour of the lens, automatically calculates the lens diameter and thickness parameters using a preset algorithm model, and calls the corresponding processing parameter library, completing the process without manual tooling changes. 10mm to The positioning and fixing of 200mm circular lenses of different specifications is achieved through an integrated design of "detection-driven adjustment + structural collaborative execution," which not only improves positioning accuracy but also significantly enhances the equipment's versatility and automation level.

[0032] In addition to the drive motor and control motherboard, the power system also includes an overload protection circuit, a power supply module for the ultraviolet curing lamp, a laser rangefinder signal processing unit and its matching display screen, which can display key parameters such as the current positioning accuracy, reagent balance and equipment operating status in real time.

[0033] The complete and detailed workflow is as follows: When it is necessary to connect the lens to be processed 16 with the lens clamp 11 to provide a basis for subsequent lens polishing, the operator or robotic arm places the lens to be processed 16 and the lens clamp 11 in sequence. Then, the drive device of the detection screw 17 is started, so that the detection screw 17 drives the detection seat 18 to adjust up and down in its set direction, so that the laser rangefinder 19 is aligned with the side edge of the lens to be processed 16 and its distance is detected in real time. If the position of the lens to be processed 16 is offset, the drive motor of the adjusting screw is started to drive the laser rangefinder 19 to adjust the position of the lens to be processed. The mounting base of the adjuster housing 21 drives the adjuster housing 21 to move, aligning the adjusting rod 25 with the lens 16 to be processed. The micro geared motor 24 drives the adjusting shaft 30, causing the threaded sleeve 28 to extend under the guidance of the guide cover 27. This allows the adjusting rod 25 on the connector 22 to push the lens to move. When adjustment in other directions is needed, the drive component of the hollow rotating platform 12 is activated to rotate it by an angle, so that the side of the lens 16 to be processed that needs adjustment faces the adjusting rod 25 and the laser rangefinder 19. The above steps are then repeated to achieve adjustment in another direction. The position of the lens to be processed 16 is adjusted. After multiple adjustments, the lens to be processed 16 can be accurately positioned. Then, the lens clamp 11 needs to be positioned. At this time, the position of the laser rangefinder 19 and the adjusting rod 25 is raised by adjusting the screw and the detection screw 17 so that they are directly facing the lens clamp 11. The vertical lifting module is then activated to attract the lens to be processed 16 through the suction cup and keep the suction cup in the attracted state. Then, the positional relationship between the lens clamp 11 and the lens to be processed 16 is adjusted by the same detection and adjustment method. After the lens clamp 11 is positioned, the adjusting rod 25 is adjusted. Move to the junction of the lens clamp 11 and the lens to be treated 16. Use the active injector 29 to deliver liquid paraffin through the hose 23 to the hose connector 26 and through the channel inside the connector 22 to the nozzle 31 on the adjusting rod 25 to the junction of the lens clamp 11 and the lens to be treated 16. With the rotation of the hollow rotating platform 12, waxing is achieved on the outer ring. During this process, the ultraviolet curing lamp 20 is activated for auxiliary irradiation, which can accelerate the solidification of paraffin and complete the connection of the two faster. Then, the connected components are sent to the next process through the mechanical wall or by the operator.
