Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to a fully automated lens assembly line. Background Technology

[0002] Optical lenses consist of numerous components, including the lens barrel, spacers, lens elements, and Mylar film. During production, these components must be assembled into the lens barrel one by one in a specific order. This assembly process involves a series of steps such as pressure testing, inspection, adhesive application, UV curing, and fastening to complete the assembly of a single lens. Currently, lens manufacturing still relies on manual methods, where individuals manually assemble the components and perform various operations during the assembly process. However, this production model has several drawbacks: First, production efficiency is low, making it difficult to meet the ever-increasing market demand; second, the labor intensity is high, and prolonged high-intensity work easily leads to worker fatigue, further affecting production efficiency and product quality; third, the precision of manual assembly is limited, which seriously affects the optical performance of the lens and cannot meet the high standards of current lens production. The problems with manual assembly are mainly reflected in: 1. In the traditional production model, many steps rely on manual operation, and delays in process connections due to human factors often occur, resulting in a slow overall production line pace. At the same time, the speed limit of manual operation is obvious, making it difficult to maintain high-speed production for extended periods, and fatigue further reduces efficiency. 1. Multiple processes are carried out sequentially, lacking a parallel processing mechanism, further lengthening the production cycle and hindering overall production efficiency. 2. Workers are required to perform monotonous and heavy tasks repeatedly for extended periods, resulting in high physical exertion, prolonged stress, and significant mental pressure. Prolonged exposure to this work environment easily leads to physical fatigue and occupational diseases, seriously harming workers' physical and mental health, while also increasing the company's human resource management costs and potential risks. 3. Manual operation inevitably involves individual differences; different workers have varying operating techniques, strengths, and precision, resulting in inconsistent product quality. Furthermore, manual inspection is prone to oversights, making real-time, accurate monitoring of the entire product lifecycle and all production stages impossible, and failing to meet modern high standards and stringent quality requirements.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The purpose of this invention is to overcome at least some of the shortcomings of the prior art and to provide a fully automated lens assembly line.

[0005] The technical solution of this utility model is as follows: This utility model provides a fully automatic lens assembly line, including: a tray loading station, an assembly station, a cap locking station, a glue dispensing station, an MTF machine, and a receiving assembly station arranged in sequence. The tray loading station is used for loading empty mirror tubes at the location of the assembly station; The assembly station is used to load the lens into the lens barrel and press it, and then transport the lens barrel to the locking station station. The locking station is used to pre-lock and lock the lens barrel, and after locking, it is sent to the dispensing station. The dispensing machine is used to dispense and cure adhesive on the lens before transporting it to the MTF machine. The MTF machine is used to transport lenses to the MTF equipment for MTF testing, and after the MTF testing is completed, the lenses are sent to the receiving and assembly machine. The receiving and assembly machine is used to transport qualified lenses to the finished product tray and unqualified lenses to the NG tray.

[0006] Furthermore, the assembly machine is a two-station assembly machine or a three-station assembly machine.

[0007] Furthermore, the dispensing machine is a three-station dispensing machine.

[0008] The beneficial effects of this invention using the above solution are as follows: it achieves automated material handling, eliminating the need for repeated manual material turnover and effectively reducing personnel requirements. It not only automatically performs assembly tasks but also automatically removes defective products during the assembly process, significantly simplifying manual operation procedures and making the production process more efficient and smooth, thus comprehensively improving production efficiency. Furthermore, the equipment uses intelligent cameras to inspect products, efficiently achieving real-time and accurate monitoring of the entire product lifecycle and all production stages.

[0016] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Please refer to the following: Figures 1 to 7 In this embodiment, the present invention provides a fully automatic lens assembly line, comprising: a tray loading station, an assembly station, a cap locking station, a dispensing station, an MTF machine, and a receiving assembly station. The tray loading station is used for loading empty mirror tubes at the assembly station position; The assembly station is used to load the lens into the lens barrel and press it, and then transport the lens barrel to the capping station. The capping station is used to pre-lock and lock the lens barrel, and after locking, it is sent to the dispensing station. The dispensing machine is used to dispense and cure adhesive on lenses before transporting them to the MTF machine. The MTF machine is used to transport lenses to the MTF equipment for MTF testing, and after the MTF testing is completed, the lenses are sent to the receiving and assembly machine. The receiving and assembly machine is used to transport qualified lenses to the finished product tray and unqualified lenses to the NG tray.

[0018] Furthermore, in different embodiments, the assembly machine is a two-station assembly machine or a three-station assembly machine, which respectively realizes two-station assembly and three-station assembly, thereby improving assembly efficiency.

[0019] Furthermore, the dispensing machine is a three-station dispensing machine, which improves assembly efficiency.

[0020] Please continue to refer to the following: Figures 1 to 7 In this scheme, when the automatic assembly line is working, the tray loading station machine uses the loading robot 2 to load the empty mirror tube on the Y-axis 4 of the tray to the transport line 3, and then the transport line drive shaft 1 drives the transport line 3 to transport the material to the right to the assembly station position. Figure 2 , Figure 3The assembly station in the middle prefers to send the lens barrel to the pressing station 7 for lens pressing after it arrives. The parts to be assembled are then assembled using the material handling component 5 via a vacuum suction pen at the assembly station. After pressing by the pressing component, they are transported by the transfer line 8 to the cover station. At the cover station, the lens barrel is transported to the flipping station 15 for glue dispensing, then the glue dispensing operation is performed in the glue dispensing mechanism 14. Subsequently, it undergoes pre-locking by the pre-locking mechanism 17, followed by locking by the locking mechanism 20. Locking defects are thrown onto the defect tray on component 19, while good products continue to the next step. Defective products are collected through component 19 and finally sent to the next station by the transfer line. At the glue dispensing station, good products are first flipped by the flipping mechanism 21 and then sent to the photographic inspection mechanism 22 for appearance inspection. Next, pre-dispensing is performed by the pre-dispensing mechanism 23. After dispensing, the product is transported to the pre-curing station. The UV transport rotation mechanism 25 then transports the product from the transport line to the UV pre-curing mechanism for pre-curing. After pre-curing, the product is transported to the next station's inspection mechanism 27 for photographic inspection. NG products are thrown into the NG receiving box at the current station by component 26, while good products are transported to component 28 for curing. After curing, the product is flipped by the flipping mechanism and transported to the MTF machine by the transport line. In the MTF module machine, the product is transported to the tray of component 30 by the tray-swinging robot 29, and then transported by component 30 to the waiting position of component 31. Component 31 then transports the tray from component 30 to component 32, and finally transports the tray to the MTF equipment for MTF inspection. After inspection, the tray is returned to component 30 by component 31, and then the tray-swinging robot 29 transports the product to the transport line, which then transports the product to the next station. In the receiving and assembly machine, qualified lenses reach the receiving gripper's pick-up position and are transported by the receiving component 34 to the finished product tray or NG tray on component 33. At this point, lens assembly is complete. The above actions operate smoothly and continuously, significantly improving production efficiency. This invention innovatively utilizes a multi-segment modular connection structure and is equipped with a multi-station vision inspection system, capable of monitoring the quality of lenses in real time and determining their qualification. In the assembly stage, most assembly stations utilize linear modules to drive the suction pen to complete the assembly operation. This design effectively avoids damage to components during assembly, ensuring both efficient equipment operation and excellent assembly results. In summary, the beneficial effects of this solution are as follows: it achieves automated material handling, eliminating the need for repeated manual material turnover and effectively streamlining personnel. It not only automatically performs assembly tasks but also automatically rejects defective products during the assembly process, significantly simplifying manual operation procedures and making the production process more efficient and smooth, thus comprehensively improving production efficiency. Furthermore, the equipment uses intelligent cameras to inspect products, achieving efficient real-time and accurate monitoring of the entire product lifecycle and all production stages.

[0021] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
