[0002] Spectacle lenses are an optical component used to improve vision problems. They are usually composed of two parts: lens material and optical design. The main function of spectacle lenses is to correct vision, allowing the wearer to clearly see distant or near objects. For vision problems such as myopia, hyperopia, and astigmatism, doctors will recommend the appropriate lens type and degree based on the specific situation. In addition, spectacle lenses can also be added with various functional designs, such as blue light protection, anti-fatigue, and anti-ultraviolet rays, to meet the needs of different groups of people. Choosing the right lens material and design is very important for protecting eye health and improving the quality of life.

[0003] At present, the production process of lenses mainly includes steps such as blank forming, lens grinding, polishing, marking, cleaning, trimming, coating, optical cold processing, protective treatment, painting treatment, quality inspection, etc., and these more continuous processes require the use of mechanized equipment such as rough and fine grinders, polishers, marking machines, and other process steps that do not use mechanized equipment, which makes the entire lens production process longer. In the actual production of lenses, manual lens transfer is required between each process (that is, after the lens is processed in the previous process, the lens needs to be transferred to the operating table or equipment of the next process), which makes the lens processing efficiency low and cannot achieve efficient continuous processing. Summary of the invention

[0006] Preferably, the processing conveyor belt includes an equipment conveyor belt having the same structure as the main conveyor belt and passing through the mechanized equipment, and a guide conveyor belt extending the equipment conveyor belt from both ends of the mechanized equipment and connected to the main conveyor belt.

[0007] Preferably, the guide conveyor belt is embedded in the joints with the main conveyor belt and the equipment conveyor belt, and a driving mechanism is provided at the bottom of the guide conveyor belt to drive it to be highly misaligned with the main conveyor belt and the equipment conveyor belt.

[0022] In order to enable ordinary technicians in the field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0023] See attached Figures 1 to 10 The lens production integrated production line shown in the figure includes film sticking (which is a protective film, usually completed manually or by film sticking equipment), plate loading (that is, placing the film-sticked lens on the processing tray to achieve the placement and relative positioning of the lens, and before placement, a positioning block is also bonded to the film-sticking side of the lens by melting and bonding with a low-temperature alloy. In the subsequent processing, the high-speed rotation drive of the lens can be achieved by clamping the positioning block), rough and fine grinding (the lens will also be cut during the rough grinding process), polishing, marking, unloading (including removing the lens from the tray and removing the positioning block bonded to one side of the lens), light measurement, inspection, cleaning, hardening, coating and finished product inspection steps.

[0024] At present, the lens production process mainly includes mechanized equipment 1, which includes a rough and fine grinder, a polisher and a marking machine in sequence. In order to connect multiple mechanized equipment 1 and other processes to form a process system for continuous lens processing, the present application designs an integrated production line, which is a main conveyor belt 3 that connects each of the mechanized equipment 1 and transports the lens tray 2. Since the lens processing includes multiple processes, in order to improve the utilization rate of the workshop space, the main conveyor belt 3 is a ring structure (such as Figure 1 As shown), and connected with each process, multiple processes of lens processing can be effectively connected and integrated, so that each process can be connected through the main conveyor belt 3, which can effectively improve the production efficiency during the lens processing process; at the same time, the main conveyor belt 3 with an annular structure further integrates each process in the space, saving the occupation of workshop space.

[0025] In actual processing, since each mechanized equipment 1 has a certain time to process the lens (such as a coarse and fine grinder), in order to avoid interference with the movement of the main conveyor belt 3 during the processing in the mechanized equipment 1, a processing conveyor belt is also arranged between each mechanized equipment 1 and the conveyor belt. The processing conveyor belt transfers the lenses on the main conveyor belt 3 to the mechanized equipment 1 for processing, and after the processing is completed, it is transferred to the main conveyor belt 3 again for transportation to the next process, thereby realizing effective connection between each processing process.

[0026] After multiple processing steps are completed, in order to solve the continuous conveying of the main conveyor belt 3, a tray unloading roller 6 is also connected to the tail end of the main conveyor belt 3. The main conveyor belt 3 conveys the processed lenses to the tray unloading roller 6 for gathering, so as to solve the conveying drive of the main conveyor belt 3.

[0027] Specifically, Figure 2 As shown, the processing conveyor belt includes an equipment conveyor belt 4 which has the same structure as the main conveyor belt 3 and passes through the mechanized equipment 1, and a guide conveyor belt 5 which extends the equipment conveyor belt 4 out of the two ends of the mechanized equipment 1 and is connected to the main conveyor belt 3. When the main conveyor belt transports the lens tray 2 loaded with the lenses to be processed to the mechanized equipment 1, the lens tray 2 on the main conveyor belt 3 is transferred through the guide conveyor belt 5 on one side, and is transferred to the equipment conveyor belt 4 again after one transfer. The lenses in the lens tray 2 can be transported to the mechanized equipment 1 through the equipment conveyor belt 4, and the start and stop of the equipment conveyor belt 4 are realized by the loading sensor, that is, after the lens tray 2 is transported to the mechanized equipment 1, the equipment conveyor belt 4 stops conveying and realizes the positioning of the lenses, and then the mechanized equipment 1 is used for processing; and after the processing is completed, the equipment conveyor belt 4 is started again to transport the lens tray 2 to the outside of the equipment, and when it is connected with the guide conveyor belt 5 on the other side of the equipment, the transfer of the lens tray 2 is realized again, and then the lens tray 2 can be transferred to the main conveyor belt 3 again through the guide conveyor belt 5 on this side to be transported to the next process, thereby effectively solving the operation interference between the lenses and the main conveyor belt 3 during long-term processing, and ensuring the continuity of the entire process.

[0028] In order to realize the mutual transfer operation between the lens tray 2 and the guide conveyor belt 5, the equipment conveyor belt 4 and the main conveyor belt 3, as shown in FIG. Figure 2-7 As shown, the guide conveyor belt 5 is embedded in the joints with the main conveyor belt 3 and the equipment conveyor belt 4, and a driving mechanism is provided at the bottom of the guide conveyor belt 5 to drive it to be highly misaligned with the main conveyor belt 3 and the equipment conveyor belt 4. The driving mechanism is preferably a cylinder (not shown in the figure), such as Figure 2 As shown, the lens tray 2 is conveyed on the main conveyor belt 3 in the direction of the arrow. Figure 3When the guide conveyor belt 5 is on the upper side of the main conveyor belt 3, the cylinder drives the guide conveyor belt 5 on this side to be lifted and higher than the main conveyor belt 3, that is, the lens tray 2 is transferred from the main conveyor belt 3 to the guide conveyor belt 5 on one side; then the guide conveyor belt 5 conveys the lens tray 2 to the upper side of the equipment conveyor belt 4 ( Figure 4 As shown), the guide conveyor belt 5 is then driven by the cylinder to move downward and below the equipment conveyor belt 4, that is, the lens tray 2 is transferred to the equipment conveyor belt 4, and then the equipment conveyor belt 4 runs to transport the lens tray 2 to the processing position in the mechanized equipment 1 and then stops transporting ( Figure 5 After the processing is completed, the equipment conveyor belt 4 continues to transport the lens tray 2 to the end of the guide conveyor belt 5 on the other side ( Figure 6 As shown), the guide conveyor belt 5 on this side is then lifted by the cylinder to transfer the lens plate 2, and then the lens plate 2 is transported to the top of the main conveyor belt 3, and the guide conveyor belt 5 on this side is moved down by the cylinder again, so that the processed lens plate 2 can be transferred to the main conveyor belt 3 ( Figure 7 As shown), the continuity between the working steps and with the main conveyor belt 3 is achieved, thereby realizing the automated processing operation of the lens.

[0029] After the above-mentioned lens processing steps are completed, the main conveyor belt 3 transports the lens tray 2 to the unloading roller 6 for collection, and the unloading roller 6 is usually as follows: Figure 8 The tilted structure shown is so that when the lens tray 2 is separated from the main conveyor belt 3 and is not driven by power, the tilted structure can realize the connection and gathering of multiple lens trays 2. When the lens tray 2 moves down on the unloading roller 6 by its gravity, it will have an impact contact with the already gathered lens tray 2. Each lens tray 2 usually contains multiple lenses. Therefore, under the action of the impact, it is easy to cause the lenses in the lens tray 2 to fall out, thereby increasing the production cost. Therefore, in order to solve this problem, a buffer mechanism extending from its side wall and retractable under the action of external force is provided on one side of the moving direction of the lens tray 2. That is, after the lens tray 2 moves down on the unloading roller 6 and contacts with the lens tray 2 that has been stationary and gathered, the contact force of the lens tray 2 at the connection can be buffered by the buffer mechanism, and the impact force can be reduced, thereby avoiding the problem of lenses falling out of the lens tray 2 and reducing the production cost of the enterprise.

[0030] Preferably, Figure 9-10As shown, the buffer mechanism includes a rubber ring 7 embedded on the outer wall of the lens tray 2, and a retractable buffer rod 8 is fitted and penetrated in the rubber ring 7. When the lens to be processed is placed in the lens tray 2, the buffer rod 8 is driven to be in an extended state, so that when the unloading roller 6 moves up and down, the contact friction between the buffer rod 8 and the rubber ring 7 is overcome, and during the retraction of the buffer rod 8, the contact buffering of the lens tray 2 when the lens tray 2 moves down is realized, thereby effectively protecting the lenses in the lens tray 2. Preferably, the buffer rod 8 and the rubber ring 7 can be replaced by a buffer structure such as a spring buffer rod 8 or a damping rod.

[0031] The principle of this application is: the integrated production line designed by this application connects the various processes in the lens processing process through the main conveyor belt 3, which can effectively improve the production efficiency and save the space occupied in the workshop during the lens processing process. The actual processing process is: the lens plate 2 is conveyed in the direction of the arrow on the main conveyor belt 3, and when it is conveyed to Figure 3 When the guide conveyor belt 5 is on the upper side of the main conveyor belt 3, the cylinder drives the guide conveyor belt 5 on this side to be lifted and higher than the main conveyor belt 3, that is, the lens disc 2 is transferred from the main conveyor belt 3 to the guide conveyor belt 5 on one side; then the guide conveyor belt 5 conveys the lens disc 2 to the upper side of the equipment conveyor belt 4, and then the guide conveyor belt 5 moves downward under the drive of the cylinder and is lower than the equipment conveyor belt 4, that is, the lens disc 2 is transferred to the equipment conveyor belt 4, and then the equipment conveyor belt 4 runs to convey the lens disc 2 to the processing position in the mechanized equipment 1 and stops conveying , that is, the lens is processed; after the processing is completed, the equipment conveyor belt 4 continues to transport the lens tray 2 to the end of the guide conveyor belt 5 on the other side, and then the guide conveyor belt 5 on this side is lifted by the cylinder to transfer the lens tray 2, and then the lens tray 2 is transported to the top of the main conveyor belt 3, and the guide conveyor belt 5 on this side is moved down by the cylinder again, so that the processed lens tray 2 can be transferred to the main conveyor belt 3, so as to achieve the continuity between the working procedures and between the main conveyor belt 3, so as to realize the automated processing operation of the lens.

[0032] After the above-mentioned lens processing steps are completed, the main conveyor belt 3 transports the lens tray 2 to the unloading roller 6, and the lens tray 2 moves down on the unloading roller 6. During the contact process with the lens tray 2, the contact friction between the buffer rod 8 and the rubber ring 7 is overcome. During the retraction of the buffer rod 8, contact buffering is achieved when the lens tray 2 moves downward, thereby effectively protecting the lenses in the lens tray 2.

[0033] The above shows and describes the basic principles, main features and advantages of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected.
