Description

Technical Field

[0001] This invention relates to the field of lens mounting technology, and in particular to an optical lens auxiliary mounting and adjustment structure. Background Technology

[0002] The precision assembly and bonding of optical lenses is a critical process in optical instrument manufacturing, and its quality directly affects the resolution, aberration correction, and overall optical performance of the imaging system. Especially in the bonding process of multi-element lenses, factors such as the coaxiality between the lenses, the uniformity of the adhesive layer, and the control of air bubbles directly determine the surface accuracy and long-term stability of the bonded parts.

[0003] Traditional optical lens bonding processes rely heavily on operator experience and manual adjustments. Mechanical clamps or simple positioning molds are typically used to radially limit the lenses, and alignment and bonding are achieved through manual rotation, translation, or tapping. This method suffers from several problems: 1. Low positioning accuracy and poor consistency: When manually placing the upper lens, it is difficult to ensure that its central axis is perfectly aligned with the lower lens, easily introducing eccentricity errors and affecting the coaxiality of subsequent optical systems.

[0004] 2. Difficulty in controlling the uniformity of the adhesive layer: Uneven force applied during manual pressing can easily lead to uneven distribution of adhesive between lenses, resulting in missing or accumulated adhesive in some areas. After curing, stress concentration can occur, reducing the bonding strength.

[0005] 3. Difficulty in removing air bubbles: If uniform and stable pressure is not applied during the bonding process, air bubbles are likely to remain in the adhesive layer, resulting in decreased light transmittance and increased scattering, which seriously affects the image quality.

[0006] 4. Low operating efficiency and reliance on skilled workers: The entire process requires repeated adjustments, observations and corrections, which places high demands on the skills of operators, and it is difficult to guarantee the stability and repeatability of the process in mass production.

[0007] To address the aforementioned issues, this invention provides an optical lens auxiliary assembly structure that can automatically complete the entire process of lens alignment, bonding, pressure holding, and auxiliary curing. This effectively solves the core problems in traditional processes, such as low positioning accuracy, uneven adhesive layer, residual air bubbles, and over-reliance on skilled workers, ensuring high consistency and high reliability of lens bonding components in mass production. Summary of the Invention

[0008] To address the aforementioned problems, the present invention provides an optical lens auxiliary adjustment structure to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this application provides the following technical solution: The present invention provides an optical lens auxiliary assembly and adjustment structure, including a jig base, several support bases, several vertical supports, limiting components, and a control module; the upper surface of the jig base is uniformly provided with limiting grooves along its circumference; several support bases are movably disposed within the limiting grooves, which are used to support the bottom layer lens; the bottom of the jig base is also provided with several adjustment components, which are connected one-to-one with the support bases, and the adjustment components are used to adjust the position of each support base; The support base has an optical axis emitter in the middle; several vertical brackets are bolted to the upper end of the support base; each support base has two vertical brackets at its upper end, and a drive assembly is slidably arranged between the two vertical brackets; a limiting member is slidably arranged on the vertical bracket; the limiting member includes a pushing member and a side pushing member driven by the pushing member and used to contact the upper lens; the pushing member drives multiple side pushing members to perform centering adjustment on the upper lens; the control module is electrically connected to the optical axis emitter, the drive assembly, the pushing member and the side pushing members.

[0010] The control module controls the horizontal to vertical side pusher to work together to complete the radial alignment of the upper lens. Then, it uses a circumferential multi-point synchronous uniform pressing method to remove air bubbles in the adhesive layer between the upper and lower lenses. Finally, in the pressure holding stage, it combines radial force enhancement and oblique side pressure to dynamically maintain and enhance concentricity and adhesion, and finally cures in an unobstructed state.

[0011] According to an advantageous embodiment, the side pusher is rotatably connected to the pushing member, and the side pusher can be controlled to switch between a horizontal support state and a vertical limiting state; when the side pusher is in the horizontal support state, the plurality of side pushers together form a support surface for temporarily supporting the upper lens; when the side pusher is switched to the vertical limiting state, the plurality of side pushers radially limit and align the upper lens from the circumferential direction.

[0012] According to an advantageous embodiment, the side pusher is provided with a guide groove, and a slide block is slidably disposed in the guide groove by an electric slider. The slide block is provided with a pressing plate by a servo motor. When the side pusher is in a vertical limiting state and completes the initial alignment of the upper lens, the control module controls each of the electric sliders to synchronously drive the pressing plate to move down, so as to apply uniform vertical pressure to the upper surface of the upper lens in a multi-point synchronous manner, so that it is parallel and attached to the bottom lens.

[0013] According to an advantageous embodiment, the pressing plate rotates between a contact position with the upper surface of the upper lens and a clearance position housed in the guide groove; after the vertical pressure is applied, the control module controls the pressing plate to rotate into the guide groove for clearance.

[0014] According to an advantageous embodiment, the pushing member includes two straight push rods and a wedge-shaped push rod, which are respectively slidably disposed inside the vertical support. The straight push rods are axially close to the jig base, and the wedge-shaped push rods are axially away from the jig base. A buffer spring is connected between the straight push rods and the wedge-shaped push rods. A drive assembly is used to drive the wedge-shaped push rods to move, thereby changing the compression of the buffer spring and adjusting the radial clamping force of the side push member on the upper lens.

[0015] According to an advantageous embodiment, two vertical supports on the same support base have strip grooves on their adjacent end faces. The drive assembly includes an electric slider disposed in each strip groove. A sliding block is connected between two opposing electric sliders. A lifting roller is rotatably disposed on the sliding block away from the axis of the fixture base. The wedge-shaped push rod is moved by the lifting motion of the lifting roller.

[0016] According to an advantageous embodiment, the pushing member is slidably disposed in the middle of the vertical support. The pushing members on the same supporting base are rotatably disposed with side pushers through two stepper motors. The side pushers have guide grooves in the middle, and a half cam is connected to one end of the stepper motor facing the guide groove. After the side pushers are in the vertical limit state and apply radial clamping force to the upper lens, the control module controls the stepper motor to drive the half cam to rotate, so that its working surface contacts the side wall of the upper lens.

[0017] According to an advantageous embodiment, the adjusting component includes a threaded rod, and an installation groove is provided on the side wall of the fixture base at a position corresponding to the limiting groove, and the installation groove is connected to the limiting groove. The threaded rod is rotatably disposed in the installation groove via a bearing, and a hexagonal groove is provided at one end of the threaded rod away from the axis of the fixture base. An adjusting block is slidably disposed inside the installation groove, and the adjusting block is threadedly connected to the threaded rod. The adjusting block is connected to the support base corresponding to the upper position.

[0018] Compared with the prior art, the optical lens auxiliary assembly structure provided by the present invention has the following beneficial effects: 1. The present invention first uses an optical axis emitter and a miniature industrial camera to perform visual reference calibration on the bottom lens and establish a precise center position reference; then, the top lens is simply placed on a support surface composed of multiple horizontal side pushers. After the centering program is started, all side pushers are turned from horizontal to vertical under the synchronous drive of stepper motors, uniformly contacting and correcting the position of the top lens from the circumferential direction. With the closed-loop control formed by real-time feedback from the miniature industrial camera, preliminary centering is achieved; then, the pressing plates distributed on each vertical bracket are pressed down synchronously and smoothly under the command of the control module. In the form of multi-point and multi-axis synchronous pressing, the vertical force on the top lens is uniform, so that it is parallel and attached to the bottom lens; this process not only spreads the adhesive evenly into a layer of uniform thickness, but also effectively removes internal air through smooth pressing, eliminating the problems of air bubble generation and uneven adhesive layer from the root.

[0019] 2. In this invention, after the bottom lens and the top lens are bonded together, they enter the pressure-holding and curing stage. First, the drive component pushes the wedge-shaped push rod, which compresses the buffer spring with a pressure sensor, so that all the side pushers radially press against the lens with a controllable increase in force to prevent radial slippage. To enhance the bonding effect, the semi-cams on each side pusher rotate and apply an oblique lateral pressure with both radial and axial components to the sidewall of the lens. This composite force field generated by multi-point collaboration further compacts the adhesive layer and squeezes out micro-bubbles, and can dynamically fine-tune the position of the lens to ensure optimal coaxiality at the start of curing. Finally, all the pressing plates are rotated and stored to avoid blocking ultraviolet rays and ensure that the adhesive layer is evenly illuminated and cured. Thus, under the multiple mechanical protections throughout the process, a bonded component with high concentricity, high strength and no internal stress is obtained. Attached Figure Description

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 10 This application will now be described in further detail.

[0032] Please refer to the following: Figure 1 , Figure 2 and Figure 4An optical lens auxiliary assembly and adjustment structure includes a fixture base 1, several support bases 2, several vertical supports 3, and several limiting components 4. The upper surface of the fixture base 1 is uniformly provided with limiting grooves 11 along its circumference. A power module is detachably installed at its bottom. A control module (integrating an image processing unit for identifying the laser spot position on the bottom lens and the edge contour of the upper lens, and calculating its center position deviation) is installed on the outer wall of the fixture base 1. The control module is electrically connected to the power module. Several support bases 2 are uniformly arranged within the limiting grooves 11. Several adjustment components 12 are also provided at the bottom of the fixture base 1, each corresponding to one of the support bases 2. A rectangular through slot 21 is formed in the middle of each support base 2. An optical axis transmitter 22 is installed inside the slot 21, and the optical axis transmitter 22 is electrically connected to the control module; several vertical supports 3 are bolted to the upper end of the support base 2, and two vertical supports 3 are installed at the upper end of each support base 2. A drive assembly 31 is slidably installed between the two vertical supports 3, and the drive assembly 31 is electrically connected to the control module; each vertical support 3 is slidably installed with a limit member 4, and the limit member 4 is electrically connected to the control module; the drive assembly 31 is used to drive the limit member 4 to move in the axial direction of the fixture base 1; the limit member 4 includes a pushing member 41 slidably installed in the middle of the vertical support 3, and the pushing members 41 on the same support base 2 are connected to a side pushing member 42 by two stepper motors synchronously controlled by the control module.

[0033] Before using the above-mentioned auxiliary assembly structure to bond the lenses, first assemble the corresponding number of vertical brackets 3 and limiting parts 4 according to the number of lenses to be bonded. At the same time, a miniature industrial camera is installed on the top of the fixture base 1 through an adjustable bracket, keeping the miniature industrial camera in the center position directly above the fixture base 1, and electrically connecting the miniature industrial camera to the control module.

[0034] This embodiment uses the precise concentric bonding of two circular optical lenses as an example for explanation. The specific assembly quantities of the corresponding vertical support 3 and limiting component 4 are as follows: Figure 1As shown; during the lens bonding process using the aforementioned auxiliary assembly and adjustment structure, the operator first manually adjusts the positions of the multiple support bases 2 on the upper side of the fixture base 1 according to the lens diameter using the adjustment component 12 (it should be noted that lens bonding usually involves bonding multiple lenses from the same batch, so adjusting the position of the support bases 2 or installing the vertical bracket 3 and the limiting component 4 are low-frequency operations and do not affect the efficiency of bonding lenses using the aforementioned auxiliary assembly and adjustment structure); then, the operator manually places the lens within the limiting area formed by the multiple support bases 2 (the lenses within this limiting area are collectively referred to as the bottom layer lenses). During this process, a miniature industrial camera monitors in real time, based on the light emitted by the optical axis emitter 22. The laser beam is used to determine if the placement position is in the center of the limiting area by aligning with the center of the bottom lens. If they coincide, the miniature industrial camera feeds the data back to the control module. At this point, the operator presses a button to "confirm" the current position and records it as a reference. During the subsequent bonding of this batch of lenses, there is no need to calibrate the position of the bottom lens; otherwise, the position of the support base 2 needs to be readjusted. After completion, a few drops of adhesive are applied to the center of the upper surface of the bottom lens (the amount of adhesive is selected according to the size of the bottom lens, and the adhesive used is a UV-curable optical adhesive). Then, the upper lens is placed, resting within the support area enclosed by the side pushers 42 (e.g., ...). Figure 5 (As shown); After placing the upper lens, the operator triggers the "Start Alignment" command, and the control module performs the following steps according to the preset program: First, the multiple side pushers 42 on the periphery are converted to a vertical state (as shown). Figure 6 (As shown) The upper lens is initially positioned and its position is corrected, and then the upper lens is further pushed by the side pusher 42 until it is in contact with the lower lens (as shown). Figures 8-9 (As described above), this process ensures that the upper lens is evenly stressed during bonding, guaranteeing that the adhesive is evenly spread on the bonding surface; finally, the bonded upper lens is pushed concentrically by the side pusher 42 to achieve centering and pressure retention, ensuring the curing effect; it should be noted that, in order to ensure bonding efficiency, after centering and pressure retention is performed by concentric pushing, ultraviolet light can be applied for 2 minutes to accelerate the hardening of the adhesive layer.

[0035] See Figure 5 The adjustment component 12 includes a threaded rod 121. The side wall of the fixture base 1 is provided with an installation groove 13 at the position corresponding to the limiting groove 11, and the installation groove 13 is connected to the limiting groove 11. The threaded rod 121 is rotatably mounted in the installation groove 13 through a bearing, and a hexagonal groove is provided at one end of the threaded rod 121 away from the axis of the fixture base 1. An adjustment block 122 is slidably disposed inside the installation groove 13, and the adjustment block 122 is threadedly connected to the threaded rod 121. The adjustment block 122 is connected to the support base 2 at the upper position.

[0036] When adjusting the position of the support base 2 according to the diameter of the bottom lens, a T-shaped hex wrench is inserted into the corresponding hexagonal groove on the threaded rod 121. By operating the T-shaped hex wrench to rotate the threaded rod 121, the adjusting block 122 can be moved within the mounting groove 13, thereby indirectly moving the support base 2. It should be noted that, normally, the upper outer wall of the limiting groove 11 is provided with scale markings, which can facilitate personnel to accurately adjust the position of the support base 2, thereby adjusting the size of the limiting area to match the diameter of the bottom lens to be placed. The scale markings in this embodiment are not shown in the diagram.

[0037] See Figure 2 and Figure 4 The pushing component 41 includes two straight push rods 411 and wedge-shaped push rods 412, which are respectively slidably disposed inside the vertical support 3. The straight push rod 411 is close to the axis of the fixture base 1, and the wedge-shaped push rod 412 is away from the axis of the fixture base 1. A buffer spring 413 is connected to one end of the straight push rod 411 and the wedge-shaped push rod 412 that are close to each other. The buffer spring 413 is disposed inside the vertical support 3.

[0038] See Figure 7 The guide groove 421 is also equipped with a slide block 423 in the middle via an electric slider, and a pressing plate 424 is mounted on the slide block 423 via a servo motor.

[0039] Initially, under the drive of the stepper motor, the pusher 42 is in a horizontal state, such as... Figure 1 and Figure 2 As shown, the upper lens is supported by a support area composed of multiple side pushers 42. Since the side pushers 42 are horizontal, the position of the upper lens is not critical. It is only necessary to ensure that each side pusher 42 is in contact with the lower end surface of the upper lens. Compared with the traditional placement, which requires centering adjustment, this method is simpler, easier to install, and more convenient to operate.

[0040] After the upper lens is placed, the side pusher 42 is gradually changed from a horizontal to a vertical position by a stepper motor drive, as shown below. Figure 6 As shown, because multiple stepper motors are controlled to rotate synchronously through the control module, the rotation process of all side pushers 42 is consistent. The side pushers 42 can perform initial positioning adjustment of the upper lens, so that the axis of the upper lens gradually coincides with the center of the lower lens. It should be noted that during the process of the side pushers 42 changing from a horizontal state to a vertical state, the worker's fingers are always pressed on the upper center area of ​​the upper lens. The overall pressure does not need to be too great. The purpose is to assist in the position adjustment of the upper lens. When all the side pushers 42 become vertical, the worker's fingers can leave the upper surface of the upper lens.

[0041] Next, the control module controls the electric slider to move the slide block 423 downward, so that the pressing plate 424 is in contact with the upper end surface of the upper lens (e.g., Figure 8 As shown, after all the pressing plates 424 are in contact with the upper surface of the upper lens, the electric slider drives the slide block 423 to continue to move downward, which can further adjust the upper lens to keep it horizontal. Since all the pressing plates 424 are evenly arranged, their synchronous downward movement will push the upper lens to be evenly stressed at all positions, and under the limit of the side pusher 42, they will be in contact with the bottom lens. After they are in contact, it can be ensured that the central axis of the upper lens and the bottom lens are coincident. Thus, the few drops of adhesive between the upper lens and the bottom lens will be evenly pressed into a thin adhesive layer. The even pushing of the side pusher 42 can keep the adhesive layer free of air bubbles after it is formed. The uniform adhesive layer formed can ensure that the curing time is consistent and can also ensure the bonding strength between the upper lens and the bottom lens.

[0042] See Figure 3 and Figure 5 Two vertical supports 3 on the same support base 2 each have a strip groove 23 on their close-to-each end face. The drive assembly 31 includes an electric slider in each strip groove 23. A sliding block 311 is connected between two opposing electric sliders. A lifting roller 312 is rotatably mounted on the sliding block 311 away from the axis of the fixture base 1.

[0043] After the upper and lower lenses are bonded together, in order to further tighten the upper and lower lenses and ensure that the two lenses do not shift during the adhesive curing process, the control module controls the electric slider to move the sliding block 311 upward along the strip groove 23. Through the cooperation of the lifting roller 312 and the wedge push rod 412, the wedge push rod 412 gradually approaches the straight push rod 411, compressing the internal buffer spring 413, thereby increasing the clamping force between the side pusher 42 and the side wall of the upper lens. It should be noted that the buffer spring 413 is equipped with a pressure sensor. The pressure sensor detects the pressure value and feeds the pressure value back to the control module in real time to adjust the compression of the buffer spring 413.

[0044] After the above-mentioned side-push clamping limit is completed, the control module further controls the servo motor to drive the pressing plate 424 to rotate, so that the pressing plate 424 leaves the upper end surface of the upper lens and is housed inside the guide groove 421 (e.g. Figure 10 As shown in the figure, it should be noted that the purpose of housing the pressing plate 424 inside the guide groove 421 is to avoid the adhesive curing time being inconsistent in different places due to the influence of the contact area of ​​the pressing plate 424 when irradiated with ultraviolet light, thereby affecting the bonding effect between the two lenses.

[0045] It should be noted that during the process of the side pusher 42 being erected and the pressing plate 424 being pressed down, the miniature industrial camera monitors the edge position of the upper lens in real time, forming a closed-loop control with the control module. The control module fine-tunes the actions of each point to ensure alignment accuracy.

[0046] See Figure 5 and Figure 7 The side pusher 42 has a guide groove 421 in the middle, and a half cam 422 is connected to the end of the stepper motor facing the guide groove 421; before irradiating ultraviolet light, the stepper motor is controlled by the control module to drive the half cam 422 to rotate. Figure 10 As shown in the diagram, the stepper motor drives the half-cam 422 to apply oblique lateral pressure to the sidewall of the upper lens. This oblique lateral pressure is arranged obliquely to the axis of the upper lens, which can increase the bonding strength between the upper and lower lenses and further prevent air bubbles in the adhesive. At the same time, the oblique lateral pressure can also make the axis of the upper lens coincide with the axis of the lower lens, further improving the bonding effect between the two lenses.

[0047] It should be noted that, during the lens bonding process using this optical lens-assisted assembly structure, the upper lens is first supported by a support area composed of multiple side pushers 42, facilitating its placement without requiring precise manual positioning. Subsequently, during the alignment of the upper and lower lenses, the side pushers 42 and the pressing plate 424 ensure even pressure distribution across all positions of the upper lens, preventing uneven adhesive thickness and air bubbles after bonding. During the subsequent pressure-holding process, the rotation of the semi-cam 422 and the sidewall of the upper lens further enhance the adhesion. Applying oblique lateral pressure during bonding tightly adheres the upper and lower lenses, significantly improving the adhesive curing effect. During the UV-assisted molding process, the synchronous repositioning of the pressing plate 424 ensures uniform adhesive curing time between the two lenses, further enhancing the lens bonding and molding effect. It should be noted that a pressure sensor is also installed on the outer wall of the semi-cam 422. This sensor detects the pressure value and feeds it back to the control module in real time to adjust the rotation angle of the semi-cam 422, applying oblique lateral pressure within an appropriate range.

[0048] In this embodiment, all components that come into contact with the lens, including the top surface of the support base 2, the contact surface of the side pusher 42, and the lower surface of the pressing plate 424, are made of aluminum alloy or stainless steel. After precision machining, the surface is anodized or chrome-plated and then ground to ensure that its flatness is better than 0.01mm and its surface roughness Ra≤0.4μm, so as to avoid scratching the lens.

[0049] During the dispensing process, the adhesive dosage must be strictly determined according to the lens diameter specified in the execution standard to avoid adhesive overflow during lens bonding. For example, for a lens with a diameter of Φ30mm, 1-2 drops are usually added to the center, with a total amount of approximately 3-5mg of UV-curable optical adhesive. For specific dosage, please refer to the technical data provided by the adhesive supplier.

The optical lens auxiliary adjustment structure according to claim 1, characterized in that: The side pusher is provided with a guide groove, and a slide block is slidably arranged in the guide groove by an electric slider. The slide block is provided with a pressing plate by a servo motor. When the side pusher is in the vertical limit state and completes the initial alignment of the upper lens, the control module controls each of the electric sliders to synchronously drive the pressing plate to move down, so as to apply uniform vertical pressure to the upper surface of the upper lens in a multi-point synchronous manner, so that it is parallel and attached to the bottom lens.

4. The optical lens auxiliary adjustment structure according to claim 3, characterized in that: The pressing plate rotates between a position in contact with the upper surface of the upper lens and a position that avoids contact within the guide groove; after the vertical pressure is applied, the control module controls the pressing plate to rotate into the guide groove to avoid contact.

5. The optical lens auxiliary adjustment structure according to claim 1, characterized in that: The pushing component includes two straight push rods and a wedge-shaped push rod that are slidably disposed inside the vertical bracket. The straight push rod is close to the axis of the fixture base, and the wedge-shaped push rod is away from the axis of the fixture base. A buffer spring is connected between the straight push rod and the wedge-shaped push rod. The driving component is used to drive the wedge-shaped push rod to move, thereby changing the compression of the buffer spring and adjusting the radial pressing force of the side pusher on the upper lens.

6. The optical lens auxiliary adjustment structure according to claim 5, characterized in that: Two vertical supports on the same support base have strip grooves on their close-to-each end faces. The drive assembly includes an electric slider in each strip groove. A sliding block is connected between two opposing electric sliders. A lifting roller is rotatably mounted on the sliding block away from the axis of the fixture base. The wedge-shaped push rod is moved by the lifting motion of the lifting roller.

7. The optical lens auxiliary adjustment structure according to claim 1, characterized in that: The pushing component is slidably disposed in the middle of the vertical support. The pushing components on the same supporting base are connected to a side pusher by two stepper motors. The side pusher has a guide groove in the middle, and a half cam is connected to one end of the stepper motor facing the guide groove. After the side pusher is in the vertical limit state and applies radial clamping force to the upper lens, the control module controls the stepper motor to drive the half cam to rotate, so that its working surface contacts the side wall of the upper lens.

8. The optical lens auxiliary adjustment structure according to claim 1, characterized in that: The adjustment component includes a threaded rod. The side wall of the fixture base has an installation groove corresponding to the limiting groove, and the installation groove is connected to the limiting groove. The threaded rod is rotatably mounted in the installation groove through a bearing. The end of the threaded rod away from the axis of the fixture base has a hexagonal groove. An adjustment block is slidably mounted inside the installation groove, and the adjustment block is threadedly connected to the threaded rod. The adjustment block is connected to the support base corresponding to the upper position.
