Description

Technical Field

[0001] This application relates to the field of auxiliary equipment for optical lens processing, and in particular to a manual optical lens front and back bonding and positioning device. Background Technology

[0002] In the manufacturing process of optical lenses, it is often necessary to apply protective films, functional coatings, and other materials to both sides of the lens. This application process requires extremely high positioning accuracy. Any positioning deviation can easily lead to the lens shifting its position, thereby affecting the lens's optical performance and even rendering the lens unusable.

[0003] There are generally two existing positioning methods for optical lens bonding processes: one is purely manual positioning, which relies on the operator's experience to adjust the lens position. This is not only inefficient, but also difficult to guarantee consistent positioning accuracy each time. Especially in batch processing, the product qualification rate fluctuates greatly. The other is to use automated positioning equipment, which can improve positioning accuracy, but the processing equipment is expensive, difficult to maintain, and specific equipment is usually dedicated to the positioning of specific workpieces, which is not suitable for small and medium batch production scenarios or small processing enterprises.

[0004] Existing manual positioning tools can only position a target lens on one side at a time. When the same lens needs to be pasted on the opposite side, the workpiece must be disassembled, flipped, and then repositioned for pasting. This process requires readjusting the positioning structure after disassembly, which is cumbersome and prone to secondary positioning deviations. Furthermore, existing manual positioning tools lack sufficient precision in the fit between positioning components, making the workpiece prone to displacement after flipping, further affecting the pasting quality.

[0005] Therefore, there is an urgent need for an optical lens front and back bonding and positioning device that is simple in structure, low in cost, accurate in positioning, and easy to manually flip. Utility Model Content

Detailed Implementation

[0020] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0021] The terms "inner" and "outer" as used in this application refer to the direction from the base surface toward the workpiece inside it, relative to the flipping platform itself, and vice versa; rather than a specific limitation on the device mechanism of this application.

[0022] The term "connection" as used in this application can mean a direct connection between components or an indirect connection between components through other components.

[0023] The terms "up" and "down" as used in this application refer to the direction from the base plate to the surface of the base when the user is facing the flipping platform, which is up and vice versa, and are not a specific limitation on the device mechanism of this application.

[0024] The manual optical lens front and back bonding and positioning device provided in this application aims to achieve precise positioning and flipping of optical lenses during the front and back bonding process, thereby solving the problems of low positioning accuracy, cumbersome operation, or high equipment cost in existing optical lens front and back bonding and positioning systems. The device includes... Figure 1 Shown: The base plate 5 has several sets of limiting structures on it; A flipping platform 6 is rotatably mounted on a base plate 5. A parts compartment 3 is fixed in the middle of the flipping platform 6, and a workpiece A to be processed is fixedly installed inside the parts compartment 3. The upper and lower sides of the flipping platform 6 are also respectively provided with: The positioning structure, in conjunction with the limiting structure on the base plate, constrains the flipping platform 6 and the parts compartment 3, maintaining the processing posture of workpiece A. The processing window, located between the positioning structures, is used to allow optical lenses to enter the flipping platform and be mounted to the surface of workpiece A via the parts compartment 3.

[0025] Therefore, the above structure can be used as Figure 7 As shown, when assembling the first optical lens, the workpiece A to be processed is installed in the parts compartment 3, and the parts compartment 3 is fixed inside the flip platform 6. The positioning structure on the first side of the flip platform 6 positions the parts compartment 3 relative to the base plate, thus maintaining workpiece A in a suitable processing posture. At this time, the optical lens can extend into the parts compartment 3 through the processing window on the second side of the flip platform 6 (located at the top of the flip platform in this state). The lens cavity on the parts compartment guides the optical lens to the target position on the workpiece, allowing the operator to reliably fix the optical lens to workpiece A by adhesive. Subsequently, when it is necessary to install the second optical lens on the other side of the workpiece, the flip platform 6 can be directly flipped, and the positioning structure originally located on the upper side of the flip platform can be flipped to the lower side. In the same manner, through the cooperation between the positioning structure and the limiting structure, the parts compartment is fixed to the base plate in a suitable processing posture. Thus, the second optical lens can enter the parts compartment 3 through another processing window located on the upper side of the flip platform 6, and be accurately adhered to the target position on the other side of workpiece A by the lens cavity on the parts compartment. Through the above-described flipping and positioning process of the flipping platform, this application can overcome the shortcomings of existing optical lens front and back pasting positioning, such as low positioning accuracy of pure manual methods, high cost of automated equipment, and cumbersome and easily deviated flipping operations. It realizes a manual positioning device with simple structure, accurate positioning, convenient operation and low cost, which can meet the needs of small and medium batch optical lens processing scenarios. Specifically, when positioning the workpiece, this application utilizes the positioning holes on the surface of the base plate as a limiting structure, and coordinates with the positioning balls 2 fixed to the upper and lower end faces of the base 1 as a positioning structure to achieve positioning of the flipping platform. Specifically, this application assembles the positioning balls onto the upper and lower planes of the base, and the parts compartment is secured by fixing screws... Figure 5 The workpiece is installed in a cavity inside the base as shown. The base, positioning ball, parts compartment, and fixing screws together form a freely tilting platform. After each tilting of the platform, the positioning ball can be positioned in the corresponding positioning hole on the positioning base plate. The positioning hole guides the positioning ball, thus achieving the matching positioning of the positioning hole and the positioning ball, thereby fixing the workpiece assembled inside the tilting platform machine. Therefore, this device ensures positioning accuracy through the one-to-one correspondence between the positioning ball and the holes in the positioning base plate. The flipping platform itself can selectively flip the workpiece to the front or back, and through the guiding and limiting functions of the positioning base plate, it can quickly flip and paste the lens onto the workpiece. The positioning process of this application only requires aligning the positioning ball as needed and placing it in the positioning hole, without repeatedly adjusting the horizontal and vertical coordinates of the positioning structure relative to the base plate, thus achieving automatic positioning. This application is easy to operate, suitable for small to medium batch optical lens processing scenarios, and has the advantages of low cost and high precision.

[0026] Specific reference Figure 2 As shown, the base 1 of this application has a first plane top surface and a second plane bottom surface arranged opposite to each other. Both planes can be configured as C-shaped to utilize the open side of the C-shaped structure as a processing window. The C-shaped structures of the upper and lower bases can be configured to be exactly the same. To achieve accurate positioning of the structure, this application can provide three mounting holes 101 on each plane of the base. The center line connecting the three mounting holes 101 can form an equilateral triangle centered on the axis of the base. The geometric center of this equilateral triangle coincides with the center of the corresponding C-shaped plane, thus the base can be stably held in a stable position, and the weight of the base itself can be used to maintain its positioning ball at a low position in the center of the positioning hole, thereby accurately maintaining the workpiece in the base in a horizontal assembly posture.

[0027] Reference Figure 3As shown, to ensure accurate installation of the positioning balls and reduce assembly errors, this application further provides an integrally formed shaft 201 on each positioning ball 2. The shaft 201 and the mounting hole 101 on the end face of the base 1 are fitted together by an interference fit to achieve a tight fit. Thus, by tightly fitting the outer circumferential surface of the shaft 201 with the inner circumferential surface of the mounting hole 101, positioning deviations caused by assembly gaps are avoided. By installing the positioning balls 2 correspondingly in the mounting holes 101 on the upper and lower planes of the base 1, the symmetrical arrangement of the mounting holes in the upper and lower planes ensures that the flipping platform, regardless of which side it is flipped to, can pass through the smooth spherical surface of the positioning balls. The weight of the flipping platform itself keeps each ball in the lowest position inside the positioning hole, thereby calibrating the attitude of the flipping platform through the positioning of the three balls in the plane. The mounting hole 101 is generally set as a through hole penetrating the base 1, and the mounting holes 101 on the upper and lower bases are set as coaxial and collinear to ensure the consistency of workpiece positioning after flipping.

[0028] refer to Figure 4 Specifically, the positioning base plate 5 of this application may be provided with a positioning countersunk hole 501, a positioning countersunk groove 502, and a positioning blind hole 503. The positioning countersunk hole 501, the positioning countersunk groove 502, and the positioning blind hole 503 can respectively adapt to the positioning balls 2 provided on the front and back sides of the flipping platform 6 to fix the posture of the workpiece on both sides. The positioning countersunk hole 501, the positioning countersunk groove 502, and the positioning blind hole 503 can achieve alignment between the flipping platform and the base plate by rotationally symmetrically fitting the spacing between the positioning balls, with the axis between the base plate and the flipping platform as the center. The horizontal displacement of the flipping platform 6 is limited by the fit between the concave positioning hole and the convex positioning ball. The diameters of the positioning countersunk hole 501, the positioning countersunk groove hole 502, and the positioning blind hole 503 are all matched with the outer diameter of the positioning ball 2, and their arrangement positions correspond one-to-one with the distribution positions of the mounting holes 101 on the base 1. Therefore, it can be ensured that the positioning ball 2 can be accurately embedded in the corresponding hole position when the flipping platform 6 is assembled with the positioning base plate 5.

[0029] Reference Figure 5 and Figure 6 The flipping platform 6 of this application includes: bases 1 respectively disposed on the upper and lower sides of the flipping platform 6, with the C-shaped openings between the upper and lower bases 1 facing away from each other; and corresponding support structures connected to the upper and lower bases on both sides of the processing window. Thus, the bases and support structures can be closed to form a rectangular cavity for accommodating the parts compartment 3.

[0030] A fixing screw 4 is provided on one side of the support structure, and the parts compartment 3 can be fixed by the fixing screw 4 to form a cavity between the base and the support structure.

[0031] The inner contour of the parts compartment 3 is adapted to the shape of the workpiece A to be positioned, in order to accommodate and limit the workpiece A, preventing it from shifting during flipping or pasting. The parts compartment 3 is permanently fixed to the flipping platform 6 by fixing screws 4 and does not need to be disassembled when workpiece A is replaced.

[0032] Specifically, the parts compartment 3 in this application includes a rectangular compartment for accommodating workpiece A. One end of the rectangular compartment is equipped with a quick-locking structure such as an elastic buckle and a knob-type pressure block for quick fixing and removal of workpiece A. The rectangular compartment also has open lens cavities on its two opposing side walls for guiding the lens to its target installation position. In other words, in this application, the workpiece A to be processed is fixed in the rectangular compartment by the quick-locking structure, and the target position of workpiece A is located in the lens cavity of the parts compartment 3. When the parts compartment 3 is fixed in the flipping platform 6 on the base plate 5, the optical lens is glued and fixed to the target position of workpiece A through the processing window of the flipping platform 6 and guided by the lens cavity.

[0033] The base 1, positioning ball 2, parts compartment 3, and fixing screw 4 can rotate synchronously. Figure 7 The preset axis shown can be freely rotated 180° to achieve the flipping operation of the workpiece, meeting the requirements for pasting the front and back of the lens. Therefore, before using the manual optical lens front and back bonding positioning device of this application, it can be confirmed that all components of the device have been assembled and are in normal condition by the following method: The shaft 201 of the positioning ball 2 is interference-fitted with the mounting hole 101 of the base 1, without loosening or offset. Furthermore, the centers of the positioning balls 2 on the upper and lower bases 1 correspond one-to-one and overlap with each other, so that the positioning balls 2 can stably support the flipping platform 6 through the equilateral triangular distribution of the positioning balls. The parts compartment 3 is permanently fixed to the internal cavity of the base 1 by the fixing screws 4, without shaking or displacement. Its built-in quick locking structure, such as the elastic buckle in the open state and the knob pressure block in the unlocked position, functions normally, and can smoothly realize the insertion and removal of workpiece A. The countersunk holes 501, countersunk grooves 502, blind holes 503, and base plate fixing holes on the positioning base plate 5 are arranged symmetrically in a hexagonal pattern on the base plate, ensuring they are free of obstructions. The base plate fixing holes are used to connect and fix the base plate with connecting components, including bolts, screws, positioning pins, and positioning blocks, to fix the base plate at the target processing position and maintain its stability. The diameter of each positioning hole matches the outer diameter of the positioning ball 2, allowing the positioning ball 2 to fit smoothly and without jamming when inserted into the hole. The positioning holes, consisting of the countersunk holes 501, countersunk grooves 502, and blind holes 503, are equidistantly and evenly distributed on the end face of the base 1 with the axis of symmetry as the center of axial symmetry, so that the positioning ball on one side of the base can be aligned with three of the positioning holes and stably fixed on the base plate. When the base is flipped, the positioning ball on the other side can rotate by a certain angle and be positioned in the other three positioning holes.

[0034] The inner cavity of the parts compartment 3 is adapted to the shape of the workpiece A to be processed, such as the optical lens carrier substrate. When the quick-locking structure is closed, it can fit tightly against the surface of the workpiece A, ensuring that the workpiece A has no displacement space. Therefore, the above-mentioned device can be used to attach optical lenses to both sides of workpiece A, such as a square glass substrate or a metal carrier, according to the following usage procedure: First, operate the quick-locking structure of parts compartment 3, pull the elastic buckle outward, and rotate the knob to open it to unlock it. Place the workpiece A to be processed smoothly into the inner cavity of parts compartment 3, ensuring that the edge of workpiece A is aligned with the positioning edge of the inner cavity of parts compartment 3. Then, reset the quick-locking structure, close the knob to close the elastic buckle, and let it automatically lock the edge of workpiece A. Rotate the knob clockwise until it is close to the surface of workpiece A, completing the quick fixation of workpiece A. At this time, workpiece A is positioned by the positioning hole and has no horizontal or vertical displacement, meeting the bonding accuracy requirements. After positioning the workpiece, the optical lens can be aligned as follows: During operation, the preset pasting position on the front of workpiece A can be determined by the fitting structure between the edge of workpiece A and the inner cavity of the parts compartment 3. Take the first optical lens, which can be flexibly configured as a convex lens, filter, or other structure according to usage requirements. Place the lens with the pasting surface facing down, aligning it with the target area on the front of workpiece A. Visually ensure that the edge of the optical lens is aligned with the edge of workpiece A. With the help of the limiting and guiding contour of the inner cavity of the parts compartment 3, align the lens with the edge of workpiece A to the target position, achieving precise fixation. Thus, this application can provide an alignment reference for the lens through the fitting accuracy between the edge of workpiece A and the edge of the lens cavity in the parts compartment 3, ensuring the initial position of the lens is accurate and controlling the deviation during assembly to within 0.05mm. After confirming that the alignment is correct, the operator can use a soft pressure block, such as a silicone pressure head, to gently press the surface of the optical lens to avoid scratching the lens coating. During the pressing process, press slowly from the edge of the lens towards the center, controlling the pressure to 5-10N to prevent the lens from breaking. Gradually expel the air between the lens and workpiece A, so that the lens is tightly bonded to the front of workpiece A. After bonding, hold the pressure for 10-15 seconds to ensure that the lens is firmly bonded to the workpiece, thus completing the optical lens bonding operation on the front of workpiece A. After the front side is pasted, the operator can gently lift the two sides of the flipping platform 6 and flip it 180°. During the flipping process, ensure that your hands avoid the parts compartment 3 and the pasted lens area, so that the positioning ball 2 under the base 1 is dislodged from the positioning countersunk hole 501 of the positioning base plate 5; keep your hands stable and slowly flip the flipping platform 6 until the flipping platform 6 rotates 180°. At this time, the reverse side of the workpiece A that was originally on the bottom side is flipped to face upwards, and the positioning ball 2 that was originally on the top of the base 1 is turned downwards. The workpiece A is always in a locked state, and the parts compartment 3 and the quick-locking structure flip synchronously with the flipping platform 6. The flipped platform 6 is slowly lowered onto the positioning base plate 5, so that the positioning ball 2 under the base 1 is precisely embedded in the positioning blind hole 503 of the positioning base plate 5. Through the concave-convex cooperation between the positioning ball 2 and the positioning blind hole 503, the horizontal displacement of the flipped platform 6 is restricted. Since the arrangement of the positioning blind hole 503 and the positioning countersunk hole 501 corresponds one-to-one with the mounting hole 101 of the base 1, the position of the reverse side of the workpiece A is completely aligned with the front side. This ensures that the pasting accuracy of the reverse side of the workpiece is consistent with that of the front side after flipping. After flipping, the second optical lens can be removed. The specific specifications of the lens can be selected according to the needs, such as a concave lens with a different focal length than the front lens or other lenses. With the adhesive side of the second lens facing down, align it with the preset adhesive area on the reverse side of workpiece A, and repeat the aforementioned alignment steps. After the lens is accurately aligned, use a soft pressure block of the same specifications as before to gently press the lens, pressing in the same way as the front lens, to complete the adhesiveing ​​of the optical lens on the reverse side of workpiece A; after adhesiveing, also maintain pressure for 10-15 seconds to ensure that the reverse lens is firmly adhered.

[0035] After the optical lenses on both sides of workpiece A are glued and stabilized, if the lens adhesive requires UV-curing glue, the flipping platform can be left to cure for 30 seconds. Then, the quick-locking structure of parts compartment 3 can be operated to unlock it, the elastic buckle can be pried open, and the knob can be turned to open the internal workpiece. The workpiece with the double-sided lens glued can then be carefully removed using tweezers or a soft suction cup, avoiding direct contact with the lenses, and workpiece A can be placed in the finished product storage box. Afterwards, the device of this application can directly place new workpieces to be processed into parts compartment 3 without disassembling parts compartment 3, and the above steps can be repeated for the processing of the next workpiece A. To ensure stable installation of optical lenses using the above-mentioned device, it is generally necessary to check whether the quick-locking structure is fully unlocked before each insertion of workpiece A to avoid forcibly inserting workpiece A and causing scratches to the parts compartment 3 or workpiece A. When locking, ensure that the structure is fully reset. If workpiece A is found to be loose after locking, the tightness of the quick-locking structure needs to be adjusted, such as replacing the spring of the elastic buckle or adjusting the stroke of the knob pressure block. Do not force it. If increased lens adhesion deviation is observed after prolonged use, priority should be given to checking whether the surface of the positioning ball 2 is worn, affecting the positioning accuracy of the flipping platform; whether the holes of the positioning base plate 5 are deformed, affecting the consistency of position before and after flipping; and whether there are scratches or deformations in the inner cavity of the parts compartment 3, affecting the limiting accuracy of workpiece A. Wearing or deformed parts should be replaced or repaired in a timely manner. If it is necessary to further improve the alignment efficiency, the fitting gap between the inner cavity of the parts compartment 3 and workpiece A can be optimized, such as controlling the gap to 0.02-0.03mm. By strengthening the fitting accuracy between workpiece A and parts compartment 3, the alignment stability of the optical lens can be indirectly improved.

[0036] When inserting / removing workpiece A and the optical lens, the movements should be gentle to avoid collision with the inner edge of the parts compartment 3; a 0.5mm thick silicone cushioning pad can be laid in the inner cavity of parts compartment 3 to reduce hard contact between workpiece A and parts compartment 3; when pressing the lens, a designated soft pressing block should be used, and direct pressing with metal tools or fingernails should be avoided; After each use, you can also use a lint-free cloth dampened with anhydrous ethanol to wipe the quick-locking structure of parts compartment 3, the surface of positioning ball 2, and the holes of positioning base plate 5 to remove residual glue or dust; apply a small amount of lubricant, such as silicone-based grease, to the moving parts of the quick-locking structure, such as the buckle shaft and knob threads, every month to ensure smooth operation; check the fixing screws 4 of parts compartment 3 every quarter to prevent loosening after long-term use.

[0037] The device of this application has the following advantages: This manual optical lens front and back bonding positioning device is not only simple in structure and easy to assemble, but also effectively ensures positioning accuracy and operational efficiency, solving the pain points of existing technologies and has high practical value and promotion significance.
