Description

Technical Field

[0001] This utility model belongs to the field of lens bonding technology, and specifically relates to an optical lens bonding machine. Background Technology

[0002] Optical lens bonding refers to the process of bonding two or more lenses or plane mirrors with matching optical surfaces into an optical component using optical adhesives or photoresist technology, according to specific technical requirements. In existing bonding processes, a small amount of adhesive is squeezed out during the pressure bonding of the lenses. The cured adhesive is highly hard and difficult to remove, requiring an additional cleaning process and reducing processing efficiency.

[0003] Chinese utility model patent CN222538322U discloses an optical lens bonding machine, including a base plate with symmetrically fixed support legs on both sides of the bottom. A lifting frame is fixedly connected to one side of the top of the base plate, and a motor is fixedly connected inside the lifting frame. A bonding mechanism is provided on the front of the lifting frame, comprising a lifting component, a glue scraping component, and a bonding component, which work together. An upper suction cup is fixedly connected to the bottom of a sliding rod. This optical lens bonding machine, through its bonding mechanism, enables rapid lens bonding while avoiding excessive pressure that could damage the lens during bonding. After bonding, excess glue is promptly scraped off to prevent residue from affecting lens use. It has a simple structure and strong practicality. However, the scraped glue cannot be collected, causing it to solidify on the scraper rod of the glue scraping component, affecting the scraping effect. Furthermore, the scraper rod needs to rotate once each time it scrapes glue, resulting in very low efficiency. Utility Model Content

A cylinder and an optical axis are fixedly installed on the worktable, and a movable plate is movably installed on the optical axis. The cylinder drives and connects to the movable plate. The movable plate has a glue-scraping opening, a scraper is provided around the periphery of the glue-scraping opening, and a baffle is provided around the periphery of the glue-scraping opening and outside the scraper. A glue-guiding slit is provided on the movable plate between the scraper and the baffle, and a collection box is fixedly installed on the movable plate below the glue-guiding slit.

[0006] Preferably, the scraper is fixedly mounted with a soft rubber scraper, and the soft rubber scraper is made of silicone.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] In this invention, the upper and lower adsorption components adsorb and fix the lenses to be bonded.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1:

[0018] This utility model provides an optical lens bonding machine, including a worktable 1. The worktable 1 is fixedly equipped with a lower adsorption assembly 2 and a lifting mechanism 3. The lifting mechanism 3 is fixedly equipped with an upper adsorption assembly 4. The worktable 1 is fixedly equipped with a cylinder 5 and an optical axis 6. A movable plate 7 is movably mounted on the optical axis 6. The cylinder 5 drives and connects to the movable plate 7. The movable plate 7 has a glue-scraping nozzle 8, a scraper 9 around the periphery of the glue-scraping nozzle 8, and a baffle 10 around the periphery of the glue-scraping nozzle 8 and outside the scraper 9. A glue-guiding slit 11 is provided on the movable plate 7 between the scraper 9 and the baffle 10. A collection box 12 is fixedly installed on the movable plate 7 below the glue-guiding slit 11. A soft glue scraper 13, made of silicone, is fixedly mounted on the scraper 9. The movable plate 7 has a pipe connector 14 communicating with the collection box 12. A waste discharge pipe 15 is provided at the bottom of the collection box 12.

[0019] Through the above technical solution, the upper adsorption component 4 and the lower adsorption component 2 of this utility model adsorb and fix the lens to be glued. After the glue is added, the lifting mechanism 3 presses down the upper adsorption component 4 to complete the gluing operation of the lens. At this time, the cylinder 5 is started, driving the movable plate 7 to rise, so that the scraper 9 at the glue scraping port 8 scrapes off the overflowing glue in one go. With the help of the baffle 10, the scraped glue is collected at the glue guide seam 11 and then falls into the collection box 12 through the glue guide seam 11, which quickly completes the glue scraping operation during gluing and improves the processing efficiency.

[0020] Example 2:

[0021] In this embodiment, the workbench 1 serves as the basic support structure for the entire device. A lower adsorption assembly 2 is fixedly installed on the upper surface of the workbench 1. This lower adsorption assembly 2 uses the principle of vacuum adsorption, employing negative pressure to firmly adsorb and fix the lower lens to be bonded. A lifting mechanism 3 is vertically installed on one side of the workbench 1. This lifting mechanism 3 can be an electric push rod or a lead screw structure driven by a servo motor, enabling precise up-and-down movement control. An upper adsorption assembly 4 is fixedly installed at the moving end of the lifting mechanism 3. This upper adsorption assembly 4 also uses vacuum adsorption to adsorb and fix the upper lens to be bonded.

[0022] On the other side of the worktable 1, a cylinder 5 and an optical axis 6 assembly are fixedly installed. The optical axis 6 adopts a high-precision linear guide structure to ensure smooth movement. A movable plate 7 is movably mounted on the optical axis 6, which cooperates with the optical axis 6 through a linear bearing to achieve up-and-down sliding. The piston rod of the cylinder 5 is connected to the movable plate 7, and the extension and retraction of the cylinder 5 drives the movable plate 7 to move up and down along the optical axis 6. A glue scraping nozzle 8 is opened at the center of the movable plate 7, and the shape of the glue scraping nozzle 8 matches the contour of the lens to be glued.

[0023] A scraper 9, made of elastic material, is provided around the periphery of the glue scraping nozzle 8. The scraper 9 has a certain degree of deformation capability. The edge of the scraper 9 maintains close contact with the edge of the lens, effectively scraping away any overflowing glue. A baffle 10 is also provided on the outside of the scraper 9, forming a flow channel between the baffle 10 and the scraper 9. A guide slit 11 is formed between the scraper 9 and the baffle 10 on the movable plate 7. This guide slit 11 is inclined to facilitate the flow of glue. A collection box 12 is fixedly installed below the movable plate 7, located directly below the guide slit 11, to collect the glue flowing down from the guide slit 11.

[0024] When performing lens bonding, the upper and lower lenses are first fixed by the lower adsorption assembly 2 and the upper adsorption assembly 4, respectively. After applying an appropriate amount of adhesive to the lens surface, the lifting mechanism 3 moves the upper adsorption assembly 4 downward, precisely aligning and pressing the upper and lower lenses together. At this time, the overflowing adhesive will seep out along the edge of the lens. The cylinder 5 is activated to push the movable plate 7 upward, so that the scraper 9 contacts the edge of the lens, scraping away the overflowing adhesive in one go. The scraped adhesive flows into the adhesive guide seam 11 under the guidance of the baffle 10, and finally falls into the collection box 12. The entire process does not require rotating the scraping mechanism; only linear motion is needed to complete the adhesive removal, greatly improving work efficiency. The collection box 12 can be disassembled and cleaned periodically to prevent the adhesive from hardening and accumulating, affecting the use of the equipment.

[0025] Example 3:

[0026] In this embodiment, a lower adsorption assembly 2 and a lifting mechanism 3 are fixedly installed on the workbench 1, and an upper adsorption assembly 4 is fixedly installed on the lifting mechanism 3. A cylinder 5 and an optical axis 6 are also fixedly installed on the workbench 1. A movable plate 7 is movably installed on the optical axis 6, and the cylinder 5 is drivenly connected to the movable plate 7. The movable plate 7 has a scraping nozzle 8, and a scraper 9 is provided around the periphery of the scraping nozzle 8. A soft rubber scraper 13, made of silicone, is fixedly installed on the scraper 9. A baffle 10 is provided around the periphery of the scraping nozzle 8 outside the scraper 9. A guide slit 11 is provided on the movable plate 7 between the scraper 9 and the baffle 10, and a collection box 12 is fixedly installed below the guide slit 11.

[0027] During the specific operation, the upper adsorption component 4 and the lower adsorption component 2 respectively adsorb and fix the upper and lower lenses to be bonded. After the operator applies an appropriate amount of optical adhesive to the bonding surface of the upper or lower lens, the lifting mechanism 3 drives the upper adsorption component 4 to press down, so that the upper and lower lenses complete the bonding operation under pressure. At this time, due to the pressure, some adhesive will overflow from the periphery of the lens.

[0028] Cylinder 5 then activates, driving the movable plate 7 to rise along the optical axis 6, causing the scraper 9 at the glue-scraping opening 8 to contact the periphery of the lens. Because the soft rubber scraper 13 mounted on the scraper 9 is made of silicone, it has good elasticity and flexibility, allowing it to closely conform to the curved shape of the lens periphery. During the ascent of the movable plate 7, the soft rubber scraper 13 completely scrapes away the excess glue overflowing from the lens periphery. A baffle 10 is positioned outside the scraper 9, forming a flow channel with the scraper 9; the scraped glue flows under the guidance of the baffle 10 into the glue-guiding seam 11.

[0029] The adhesive guide slit 11 is designed with an inclined structure to facilitate the smooth flow of adhesive into the collection box 12 below. The collection box 12 is detachable for easy periodic cleaning of the collected adhesive. The entire adhesive scraping process is completed in a single upward movement of the movable plate 7, without the need for rotation or other complex movements, greatly improving adhesive cleaning efficiency.

[0030] In this embodiment, the silicone soft scraper 13 has excellent wear resistance and chemical resistance, maintaining its scraping effect for a long time. Simultaneously, the softness of the silicone material prevents scratches on the lens surface, ensuring the lens's optical performance remains unaffected. The coordinated design of the scraper 9 and the baffle 10 effectively collects the scraped adhesive, preventing adhesive residue from hardening on the equipment and affecting subsequent operations.

[0031] This structural design allows the optical lens bonding machine to immediately clean up excess adhesive after lens bonding, eliminating the need for additional cleaning procedures and significantly improving production efficiency. Simultaneously, because the adhesive is promptly cleaned and collected, the impact of adhesive curing on the equipment and lenses is avoided, ensuring the stability of product quality.

[0032] Example 4:

[0033] In this embodiment, the movable plate 7 is equipped with a pipe connector 14, which is connected to the internal space of the collection box 12 via a pipe. The pipe connector 14 is located on the upper side of the collection box 12, and its interface adopts a standard quick connector design for easy connection with external negative pressure equipment. When the gluing machine is working, the external negative pressure equipment continuously provides a negative pressure environment to the inside of the collection box 12 through the pipe connector 14. This negative pressure is transmitted to the glue scraping area through the glue guide seam 11.

[0034] During the lens bonding process, when the upper adsorption component 4 presses the lens down to complete the bonding, excess adhesive will overflow along the lens edge. At this time, the cylinder 5 drives the movable plate 7 to rise, so that the scraper 9 at the adhesive scraping nozzle 8 contacts the lens edge, scraping away the overflowing adhesive in one go. The scraped adhesive flows to the adhesive guide seam 11 area under the guidance of the baffle 10. Due to the continuous negative pressure state maintained in the collection box 12, the adhesive will be quickly sucked into the collection box 12 through the adhesive guide seam 11.

[0035] The negative pressure system operates as follows: When the negative pressure unit is started, a stable negative pressure environment is formed in the collection box 12 through the pipe joint 14. This negative pressure extends to the scraping area through the adhesive guide slit 11. At the instant the scraper 9 scrapes off the adhesive, the suction force generated by the negative pressure immediately acts on the adhesive surface, causing the adhesive to quickly enter the collection box 12 through the adhesive guide slit 11. This design effectively prevents adhesive from dripping or remaining during the scraping process, ensuring a clean and efficient scraping process.

[0036] The connection between the pipe connector 14 and the collection box 12 is sealed to ensure the stability of the negative pressure environment. The collection box 12 is equipped with a filter to prevent glue from entering the negative pressure piping system. After the bonding operation is completed, the connection between the pipe connector 14 and the negative pressure machine can be disconnected for easy cleaning of the collection box 12. This embodiment, through its negative pressure-assisted collection design, significantly improves glue removal efficiency and avoids the secondary pollution problems that may occur with traditional glue scraping methods.

[0037] In practical implementation, the installation position of the pipe connector 14 is optimized to ensure that it does not affect the movement of the movable plate 7 while guaranteeing the best negative pressure effect. The volume design of the collection box 12 takes into account the maximum amount of glue that may be generated in a single gluing operation, ensuring sufficient collection space. The entire system ensures efficient glue removal while also taking into account the ease of maintenance of the equipment.

[0038] Example 5:

[0039] In this embodiment, the collection box 12 is equipped with a waste discharge pipe 15 at the bottom for discharging the collected glue. During operation, the upper adsorption component 4 and the lower adsorption component 2 respectively adsorb and fix the lens to be glued. After adding glue, the lifting mechanism 3 drives the upper adsorption component 4 to press down, so that the lens to be glued completes the gluing operation. At this time, the cylinder 5 is activated, driving the movable plate 7 to rise along the optical axis 6, so that the scraper 9 at the glue scraping port 8 contacts the edge of the lens. The scraper 9 scrapes off the glue overflowing from the edge of the lens in one go, while the baffle 10 prevents glue from splashing and confines the scraped glue to the area between the scraper 9 and the baffle 10.

[0040] The scraped-off glue flows into the glue guide slit 11 under gravity. The glue guide slit 11 is designed with an inclined structure to facilitate the rapid flow of glue to the collection box 12. The collection box 12 is located directly below the glue guide slit 11 and receives the glue flowing down from the glue guide slit 11. The inside of the collection box 12 has an inclined bottom surface, allowing the glue to flow naturally to the waste discharge pipe 15.

[0041] The waste discharge pipe 15 is located at the lowest point of the collection box 12 and is connected to the interior of the collection box 12. When the glue accumulates to a certain amount in the collection box 12, it can be discharged through the waste discharge pipe 15. The waste discharge pipe 15 can be connected to an external collection container or waste liquid treatment system to achieve centralized treatment of the glue. The waste discharge pipe 15 is made of corrosion-resistant material to ensure that it will not be damaged by glue corrosion during long-term use.

[0042] This embodiment achieves automatic collection and discharge of scraped adhesive by setting up a waste discharge pipe 15. Compared with the existing technology that requires manual cleaning of cured adhesive, this embodiment can continuously and efficiently handle the problem of adhesive spillage. The design of the waste discharge pipe 15 allows the adhesive to be discharged from the collection box 12 in a timely manner, preventing the adhesive from solidifying and accumulating in the collection box 12, which would affect subsequent use. At the same time, this design also reduces manual intervention and improves the automation level and production efficiency of the adhesive bonding operation.

[0043] The entire glue collection and discharge process is synchronized with the bonding operation, requiring no additional downtime. Once bonding is complete, the glue scraping action is immediately executed, and the scraped glue is then collected and discharged. This integrated design ensures the continuity and stability of the bonding process, making it particularly suitable for the needs of high-volume lens bonding production.
