Description

Technical Field

[0001] The invention relates to the technical field of sunglass lens processing, and in particular to a production process of an anti-scattered reflected light POL lens. Background Art

[0002] POL is polarizing film, the full name is polarizing film. The imaging of LCD must rely on polarized light. All LCDs have two polarizing films in front and behind that are close to the LCD glass, forming a liquid crystal film with a total thickness of about 1mm. If any polarizing film is missing, the liquid crystal film cannot display images. 3D glasses use this principle, so it can also be applied to the production and processing of sunglasses lenses.

[0003] In the prior art, sunglasses lenses need to be ground and polished during the production and processing process. In the existing production process, the polishing operation is mostly carried out by a special polishing machine. The polishing machine can grind and polish the outside of the fixed lens through the polishing assembly assembled inside it. The polishing assembly is mainly composed of a grindstone and a turntable that can drive it to rotate. As the working time increases, the grindstone will gradually wear out and need to be replaced, but in fact only the grindstone is worn out. The frequency of disassembly and maintenance of the turntable is much lower than the frequency of replacement of the grindstone. When the grindstone is replaced in the existing process, the turntable is removed together with the worn-out grindstone, and the turntable and the grindstone are mostly connected and fixed by bolt fixings during installation operations, which makes the disassembly, replacement and installation and fixing operations of the entire polishing assembly relatively cumbersome, affecting the production efficiency of the entire process. Therefore, the present invention provides a production process for anti-scattered reflected light POL lenses to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a production process for anti-scattered reflected light POL lenses by arranging a turntable and a connecting seat as well as a grindstone and a spring in the polishing assembly in the polishing process.

[0050] In this embodiment, if Figure 6 and Figure 8As shown, a sliding groove 21 is provided on the inner side of the connecting seat 8, and two groups of first sliders 19 and second sliders 20 are movably sleeved in the sliding groove 21 and are symmetrically distributed. The bottom end of the second slider 20 is fixedly connected with a movable plate 23 extending to the outside of the connecting seat 8, and the outside of the movable plate 23 is fixedly connected with a plug-in column 24. The sliding groove 21 provided on the inner side of the connecting seat 8 can provide sufficient space for the sliding of the first slider 19 and the second slider 20. The second slider 20 is trapezoidal as a whole, and the first slider 19 is long and fits between the inclined surface of the outside of the second slider 20. When the first slider 19 is pressed down by an external force, the inclined surface can push the second slider 20 to slide on the inner side of the sliding groove 21. During the sliding process of the second slider 20 in the sliding groove 21, the plug-in column 24 can be driven to move through the transmission of the movable plate 23, thereby changing the connection relationship between the plug-in column 24 and the turntable 3 and the grindstone 9. The outside of the first slider 19 is fixedly connected to a push rod 22 extending to the outside of the connecting seat 8, and the end of the push rod 22 is fixedly sleeved with a slide plate. A connecting groove 30 that matches the shape of the push rod 22 is provided on the connecting seat 8, and the connecting groove 30 is connected to the sliding groove 21. The slide plate at the end of the push rod 22 is located on the outside of the connecting seat 8, which can facilitate the staff to operate the connecting seat 8, thereby adjusting the positions of the first slider 19 and the second slider 20 inside the connecting seat 8. A hidden groove that matches the shape of the slide plate is provided on the outside of the connecting seat 8, and the slide plate is located on the inner side of the hidden groove to avoid accidental touch. The outside of the slide plate is also provided with evenly distributed friction patterns, which can increase the friction force by increasing the contact area with the fingers of the staff, thereby facilitating the operation of the slide plate. The connecting groove 30 can ensure that the range of movement of the push rod 22 and the slide corresponds to the range of movement of the first slider 19 in the sliding groove 21.

[0051] In this embodiment, if Figures 6 to 9As shown, the outer part of the first slider 19 is fixedly connected with a limit strip 27, and the middle part of the outer side of the limit strip 27 is fixedly connected with a positioning convex strip 31, and the sliding groove 21 is provided with a limit slot 28 corresponding to the position of the limit strip 27, and the limit slot 28 is provided with three groups of evenly distributed positioning slots 29 that are adapted to the shape of the positioning convex strip 31, and the inner part of the limit strip 27 is provided with a deformation cavity 32, and the deformation cavity 32 is provided with a first weakening groove in the area close to the positioning convex strip 31, and the inner side wall of the sliding groove 21 is fitted with the outer surfaces of the first slider 19 and the second slider 20, so as to realize the auxiliary function of the first slider 19 and the second slider 20 in the process of movement. Limiting, the limiting strip 27 outside the first slider 19 is sleeved in the limiting groove 28 inside the sliding groove 21, and the first slider 19 can be assisted in limiting during the up and down movement of the first slider 19 to avoid the first slider 19 from being misplaced during the sliding process. At the same time, the three groups of positioning grooves 29 in the limiting groove 28 correspond to the different position states of the first slider 19 in the sliding groove 21, and also correspond to the position state of the plug-in column 24. When the positioning convex strip 31 is docked with the uppermost positioning groove 29, the first slider 19 is located in the top area of ​​the sliding groove 21, and the plug-in column 24 passes through the second fixing hole 18 and docks with the first fixing hole 16, and the grinding stone 9 The first slider 19 is located in the middle area of ​​the sliding groove 21, and the plug-in column 24 is inserted into the second fixing hole 18, but completely withdrawn from the first fixing hole 16. At this time, the turntable 3 is in a fixed state, and the grindstone 9 is unlocked, and the grindstone 9 can be disassembled and replaced separately. When the positioning convex strip 31 is docked with the positioning groove 29 of the lowest layer, the bottom end of the first slider 19 and the bottom end of the second slider 20 are in the same horizontal plane, and the plug-in column 24 is completely withdrawn from the second fixing hole 18 and the first fixing hole 16, and the lock of the turntable 3 and the grindstone 9 is released at the same time, which is convenient for the grindstone 9. The disassembly and replacement of the limit strip 27 and the disassembly and maintenance of the turntable 3 are carried out. The deformation cavity 32 opened in the limit strip 27 allows the limit strip 27 to move a certain deformation space through the deformation cavity 32 after being squeezed from the outside, which is convenient for the sliding of the first slider 19. The first weakened groove opened in the deformation cavity 32 reduces the thickness of the limit strip 27 at this location, making the strength of the limit strip 27 at this location weaker, and can guide the deformation state of the limit strip 27 after being squeezed, so that the deformation area is symmetrically distributed on both sides of the positioning convex strip 31, thereby avoiding the positioning convex strip 31 from deviating during the sliding process of the first slider 19, and ensuring the accuracy of the positioning of the positioning convex strip 31 in cooperation with the positioning groove 29.

[0052] In this embodiment, if Figures 3 to 6As shown, an assembly groove 10 that matches the shape of the grindstone 9 is provided at the bottom of the turntable 3, and a positioning tube 11 is fixedly mounted on the middle part of the turntable 3, a socket 14 is fixedly connected to the inner side of the grindstone 9, and a plug-in groove that surrounds the outer side of the positioning tube 11 and matches the shape of the plug-in socket 14 is provided at the bottom of the turntable 3. After the turntable 3 is docked with the grindstone 9, the grindstone 9 is partially embedded in the assembly groove 10 to ensure the stability of the connection between the grindstone 9 and the turntable 3 after being fixed. The socket 14 on the grindstone 9 is inserted into the plug-in groove after the grindstone 9 is connected to the turntable 3, thereby further increasing the contact area between the grindstone 9 and the turntable 3 and enhancing the stability of the grindstone 9 after installation and fixation. A limiting groove 28 matching the size of the plug-in column 24 is provided on the inner side of the positioning tube 11, and a first fixing hole 16 matching the size of the plug-in column 24 and corresponding to the position of the second fixing hole 18 is provided on the inner side of the plug-in seat 14. A cross clip 12 is fixedly connected to the bottom of the positioning tube 11, and a cross clip 15 matching the shape of the cross clip 12 is provided in the plug-in seat 14. After the assembly between the grindstone 9 and the turntable 3 is completed, the position of the first fixing hole 16 on the plug-in seat 14 corresponds to the position of the second fixing hole 18 on the positioning tube 11, so that the plug-in column 24 can penetrate the second fixing hole 18 and then embed the end into the first fixing hole 16, while realizing the connection and fixation of the turntable 3 and the grindstone 9, so that the entire installation and disassembly operations can be completed through a set of structures, reducing the use of parts and simplifying the operation process.

[0053] In this embodiment, if Figure 10 to Figure 11 As shown, a storage cavity 33 is provided on the inner side of the second slider 20, and a spring piece 26 is fixedly connected between the inner walls of the two groups of storage cavities 33 and the outer side of the movable plate 23. The upper area of ​​the spring piece 26 is S-shaped, and the end of the spring piece 26 is close to the inner wall of the storage cavity 33 and a second weakening groove is provided. The bottom end of the spring piece 26 is U-shaped, and the middle of the bottom end of the spring piece 26 is recessed toward the inner side of the spring piece 26 and provided with a third weakening groove. The storage cavity 33 provided on the inner side of the second slider 20 can provide space for the deformation of the upper area of ​​the spring piece 26, and the spring piece 26 is squeezed. The S-shaped bending area generates a The spring sheet 26 contacts and deforms after the contact, deforming toward the inside of the storage cavity 33. The setting of the second weakened groove makes the spring sheet 26 thinner and weaker at this location, making it easy to deform. The two sides of the bottom end area of ​​the spring sheet 26 are fixedly connected to the outside of the movable plate 23 respectively, and the connection point between the spring sheet 26 and the second slider 20 is coordinated to ensure the stability of the basic position of the spring sheet 26, so that the spring sheet 26 can achieve the basic limiting effect on the second slider 20 through its own elastic force, so that the second slider 20 can drive the plug-in column 24 to connect and fix the turntable 3 and the grindstone 9 through the movable plate 23.

[0054] In this embodiment, if Fig.11As shown, the inner side of the spring piece 26 is fixedly connected with a symmetrically distributed first support piece 35 and a second support piece 36, and the outer side of the spring piece 26 is provided with a first movable opening 34 and a second movable opening 37 that are adapted to the width values ​​of the first support piece 35 and the second support piece 36, and the outer side of the first support piece 35 is provided with a third movable opening 25 that matches the width value of the spring piece 26. When the spring piece 26 is deformed to a certain extent, the ends of the first support piece 35 and the second support piece 36 can fit between the outer side of the movable plate 23 to provide auxiliary support for the movable plate 23, thereby enhancing the elastic force of the spring piece 26 on the second slider 20 and the movable plate 23. The first movable opening 34 opened on the outer side of the spring piece 26 can provide space for the movement of the first support piece 35, and the third movable opening 37 opened on the outer side of the spring piece 26 can provide space for the movement of the first support piece 35. The second movable opening 37 can provide space for the movement of the second support piece 36. The outer edge of the first support piece 35 fits against the inner wall of the first movable opening 34, and the outer edge of the second support piece 36 fits against the inner wall of the second movable opening 37, so that the first support piece 35 and the second support piece 36 can not only provide auxiliary support, but also assist in limiting and guiding the unfixed area in the middle of the spring piece 26 to prevent the spring piece 26 from being misplaced or offset during the deformation process. The third movable opening 25 opened in the first support piece 35 allows the first support piece 35 to be integrally mounted on the outer side of the second support piece 36, which can facilitate the formation of a cross structure between the second support piece 36 and the first support piece 35, and further limit the movement of the second support piece 36 to enhance the limiting and guiding performance.

[0055] The working principle provided by the present invention is that when in use, the operating console 6 opens the lifting protection window outside the polishing chamber of the polishing machine 1, exposes the fixed plate 2 and the polishing assembly, places the lens to be processed on the fixed plate 2 and fixes it, closes the polishing chamber, and the operating console 6 controls the fixed plate 2, the servo motor 4 and the injection pipe 5 to work. After the fixed plate 2 fixes the lens, it lifts it to a position corresponding to the working area of ​​the polishing assembly. The servo motor 4 works and drives the polishing assembly to grind and polish the outside of the lens through its driving shaft, and moves along the guide of the arc guide rail 7 to grind different positions. The injection pipe 5 continuously sprays polishing liquid to act on the lens between the rotating plate 3 and the fixed plate 2 until the lens is completely ground and polished.

[0056] When the turntable 3 or the grinding stone 9 needs to be disassembled, replaced or repaired, the slide plate outside the connecting seat 8 is toggled, and the first slide block 19 is driven by the transmission of the push rod 22 to slide along the guide of the limit strip 27 and the limit slot 28 on the inner side of the sliding slot 21, and then the second slide block 20 is pushed to move, and the second slide block 20 drives the movable plate 23 to move and compress the spring piece 26, and the plug-in column 24 on the movable plate 23 moves with the movement of the movable plate 23.
