Description

Technical Field

[0001] The present application relates to the technical field of lens production, and in particular to a material feeding and dividing mechanism of an integrated eyeglass lens production line. Background Art

[0002] Spectacle lenses are transparent materials used to correct vision, protect the eyes or for decorative purposes. They are mainly divided into glass lenses, resin lenses and PC lenses. Spectacle lenses can also be classified according to their functions, such as anti-blue light lenses, anti-fatigue lenses, anti-fog lenses, etc. These lenses are targeted at specific usage scenarios and needs. For example, anti-blue light lenses can reduce the blue light damage to the eyes from electronic screens, and are suitable for people who use computers or mobile phones for a long time; anti-fatigue lenses use special optical design to reduce the fatigue caused by long-term use of the eyes.

[0003] At present, the lens processing process usually includes: scanning detection (the lens placement frame where the lens is placed can be pasted with a QR code information recording the placed lens, such as the lens structure shape, etc.), optometry (checking the brightness of the mirror surface), grinding (grinding the shape of the lens to a structure that fits the frame) and other process steps. By connecting each process through the main conveyor belt, an integrated production and processing line for lenses can be formed, thereby improving the processing efficiency of lenses and reducing the error rate and scrap rate of lens processing.

[0004] At present, after the various processes of the lens are connected and continuously processed by the main conveyor belt, the lens placement frame for placing the initial lens to be processed needs to be manually placed at the starting end of the main conveyor belt to realize the continuous processing and production of the lens. The lens requires a certain processing time in each processing step, so the lens placement frames placed on the main conveyor belt need to be placed at intervals to avoid contact and squeezing each other (see the attached manual). Figure 1 As shown in the figure, the lens may fall off after the lens placing frame is turned over, and the placement interval (including the interval distance and the interval time) of the lens placing frame needs to be controlled manually, which cannot effectively improve the efficiency of continuous production of lenses and also increases labor costs. Summary of the invention

[0005] In response to the above-mentioned problems, the present application aims to provide a feeding and dividing mechanism for an integrated eyeglass lens production line, which can realize the interval feeding operation of the lens placement frame, effectively solving the operational difficulty caused by the current need for manual control of the placement interval of the lens placement frame, and effectively improving the production efficiency of continuous lens processing.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted in the present application is as follows: a loading and dividing mechanism of an integrated eyeglass lens production line, the production line has a main conveyor belt connecting multiple processing equipment, and is characterized in that: the loading and dividing mechanism is arranged on one side of the starting end of the main conveyor belt, and the loading and dividing mechanism can place multiple overlapping lens placement frames, and drive the single lens placement frames to be separated one by one, and drive the single lens placement frames to the main conveyor belt.

[0007] Preferably, the material feeding and dividing mechanism comprises a dividing conveyor belt which is intermittently connected to the main conveyor belt, and a dividing device which clamps and vertically drives the lens placement frame is arranged on the upper side of the dividing conveyor belt.

[0008] Preferably, the material dividing device comprises clamping cylinders symmetrically arranged on both sides of the lens placement frame, and a lifting cylinder for driving the clamping cylinder to move vertically is also arranged on the top of each clamping cylinder.

[0009] Preferably, a stacking conveyor belt is also provided at intervals on the rear side of the distribution conveyor belt in the direction of travel.

[0010] The beneficial effect of the present application is that the loading and dividing mechanism can place multiple overlapping lens placement frames and drive the individual lens placement frames to separate one by one, and after separation, the individual lens placement frames are transferred to the main conveyor belt, thereby performing the interval loading operation of the lens placement frames, effectively solving the operational difficulty currently existing in the need for manual control of the placement interval of the lens placement frames, and effectively improving the production efficiency of continuous lens processing.

[0019] 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.

[0020] See attached Figures 1 to 7 The feeding and distributing mechanism of an integrated eyeglass lens production line is shown, and the production line has a main conveyor belt 1 connecting multiple processing equipment, and the lens processing equipment connected to the main conveyor belt 1 mainly includes optometry equipment, grinding equipment, etc. The lens processing process usually includes: scanning detection, optometry, grinding and other process steps. The main conveyor belt 1 is used to connect the various processes to form an integrated production and processing line of lenses, improve the processing efficiency of lenses, and reduce the error rate and scrap rate of lens processing.

[0021] In order to solve the problem of currently needing to manually place and control the placement interval of the lens placement frames, the present application is designed with a loading and dividing mechanism, which is arranged on the starting end side of the main conveyor belt 1. The loading and dividing mechanism can place multiple overlapping lens placement frames 2, and drive the individual lens placement frames 2 to be separated one by one, and drive the individual lens placement frames 2 to the main conveyor belt 1. During operation, after manually loading the lenses into the lens placement frame 2 (usually a plurality of lenses to be processed are placed in the lens placement frame 2), the plurality of lens placement frames are stacked vertically, and the stacked lens placement frames 2 are placed as a whole on the loading and dividing mechanism. At the same time, the loading and dividing mechanism separates the stacked plurality of lens placement frames 2 one by one according to the travel positions of the lens placement frames 2 on the main conveyor belt 1, and transports the separated single lens placement frames 2 to the main conveyor belt 1 for transportation. When the last lens placement frame 2 placed on the main conveyor belt 1 reaches the specified position (a sensor can be set for detection so as to maintain a suitable interval with the lens placement frame 2 placed later), the loading and dividing mechanism separates another lens placement frame 2 to the main conveyor belt 1 for transportation, thereby effectively solving the operational difficulty currently existing in the need for manual control of the placement interval of the lens placement frames 2, and effectively improving the production efficiency of continuous lens processing.

[0022] Specifically, Figure 2-4 As shown, the feeding and distributing mechanism comprises a distributing conveyor belt 3 which is spaced apart from the main conveyor belt 1, and a distributing device which clamps and vertically drives the lens placing frame 2 is arranged on the upper side of the distributing conveyor belt 3. The distributing device can place a plurality of stacked lens placing frames 2 one by one on the distributing conveyor belt 3 (such as Figure 5When the previous lens placement frame 2 is transferred to the designed position on the main conveyor belt 1, the material distribution device continues to place a lens placement frame 2 on the material distribution conveyor belt 3, and the material distribution conveyor belt 3 is started to transfer the lens placement frame 2 to the main conveyor belt 1 for transportation.

[0023] To realize the material separation operation of stacked multiple lens placement frames 2 one by one, as Figure 3-4 As shown, the material distribution device includes clamping cylinders 4 symmetrically arranged on both sides of the lens placement frame 2, and a lifting cylinder 5 is also arranged on the top of each clamping cylinder 4 to drive it to move vertically. Among them, a clamping plate clamped with the side wall of the lens placement frame 2 is also arranged at the piston end of the clamping cylinder 4. When performing the material distribution operation, the lifting cylinder 5 drives the clamping cylinder 4 to move up (the stacked lens placement frames 2 are statically placed on the material distribution conveyor 3), so that the clamping plate corresponds horizontally to the side wall of the second layer of lens placement frames 2 from bottom to top, and then the clamping cylinder 4 drives the clamping plate to clamp the side wall of the second layer of lens placement frames 2 ( Figure 5 The lifting cylinder 5 then drives the remaining lens placement frame 2 in the clamped state to move upward as a whole and separate from the lens placement frame 2 of the first layer ( Figure 5 As shown on the right side), the material distribution conveyor belt 3 is then started to transfer the lens placement frame 2 to the main conveyor belt 1 for transportation ( Figure 6 The material distribution and intermittent loading operation of one lens placement frame 2 is completed. After the transfer, the material distribution conveyor belt 3 stops conveying, and the lifting cylinder 5 places the remaining lens placement frames 2 on the material distribution conveyor belt 3 again ( Figure 6 As shown on the right side, after waiting for the lens placement frame 2 that has just been divided to be transferred to the designed position on the main conveyor belt 1, the next division and loading operation is carried out.

[0024] Preferably, in order to facilitate the setting of the clamping cylinder 4 and the lifting cylinder 5, a protective cover is provided on the outside of the material distribution conveyor belt 3, and the clamping cylinder 4 and the lifting cylinder 5 are arranged on the side walls of the protective cover on both sides of the material distribution conveyor belt 3 (in the figure, they are arranged on both sides of the traveling direction of the material distribution conveyor belt 3, which is convenient for the display of the clamping cylinder 4 and the lifting cylinder 5, and the actual arrangement on both sides of the material distribution conveyor belt 3 can avoid the obstruction and interference problem caused by the lens placement frame 2 placed later on the material distribution conveyor belt 3), which is convenient for the setting and operation of the clamping cylinder 4 and the lifting cylinder 5, and at the same time, the stacked higher lens placement frame 2 is also protected by the protective cover to avoid the problem of tipping over due to external force contact.

[0025] For the convenience of stacking, the lens placement frame 2 can be stacked more, such as Figure 2As shown, a stacking conveyor belt 6 is provided at intervals on the rear side of the material distribution conveyor belt 3 in the direction of travel. The operator can place multiple lens placement frames 2 loaded with lenses and stacked on the stacking conveyor belt 6 in advance. After the lens placement frames 2 on the material distribution conveyor belt 3 are distributed and loaded, the stacking conveyor belt 6 can be started to transfer the single lens placement frames 2 to the material distribution conveyor belt 3 for continuous distribution and loading operations. The actions between each conveyor belt and the driving cylinder are connected through the control system and the sensor.

[0026] The principle of the present application is: a loading and distributing mechanism is set at the starting end of the main conveyor belt 1 of the lens production line. During operation, a plurality of lens placement frames 2 loaded with lenses and stacked are manually placed on the stacking conveyor belt 6 in advance, and then the stacking conveyor belt 6 transfers the single lens placement frame 2 to the distributing conveyor belt 3. During the material dividing operation, the lifting cylinder 5 drives the clamping cylinder 4 to move upward, so that the clamping plate corresponds horizontally to the side wall of the lens placing frame 2 of the second layer from bottom to top, and then the clamping cylinder 4 drives the clamping plate to clamp the side wall of the lens placing frame 2 of the second layer, and then the lifting cylinder 5 drives the remaining lens placing frames 2 in the clamped state to move upward as a whole and separate from the lens placing frames 2 of the first layer, and then the material dividing conveyor 3 is started, and the lens placing frames 2 are transferred to the main conveyor 1 for transportation, that is, the material dividing and interval loading operation of one lens placing frame 2 is completed. After the transfer, the material dividing conveyor 3 stops conveying, and the lifting cylinder 5 places the remaining lens placing frames 2 on the material dividing conveyor 3 again, and waits for the lens placing frames 2 that have just been divided to be transferred to the designed position on the main conveyor 1 before the next material dividing and loading operation is carried out.

[0027] When the lens placement frames 2 on the material distribution conveyor belt 3 have been divided and loaded, the stacking conveyor belt 6 can be started to transfer the single lens placement frames 2 to the material distribution conveyor belt 3 for continuous material distribution and loading operations.

[0028] 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.
