Description

Technical Field

[0001] The present invention relates to the technical field of 3D glasses production, and particularly to a glasses lens processing device. Background Art

[0002] A 3D glasses is an eye that enables different images to pass through the left and right lenses into a person's left and right eyes, and then synthesizes a 3D stereoscopic image through the brain. It has a wide range of applications in cinemas, arcades, and 3D experience halls. By watching the processed 3D images through 3D glasses, the stereoscopic effect is better. 3D glasses can be classified into color difference type, time division type, and polarized light type according to the principle. Among them, the two lenses of the polarized light type 3D glasses are two polarizers, and light has the characteristics of waves, so it has a vibration direction. The principle of the polarized light type 3D glasses is to install a horizontal polarizer and a vertical polarizer at the positions of the two lenses of the 3D glasses respectively, so that only horizontal polarized light and vertical polarized light can pass through the left and right lenses respectively, and then the left and right eyes receive different images, and then are synthesized into a stereoscopic image through the brain. And the polarizer has a direction. For example, if the horizontal polarizer is rotated 90 degrees, it is a vertical polarizer. Therefore, the angle of the polarizer is consistent with the direction of polarization. So when producing polarized light type 3D glasses, the angle of the polarizer is very crucial.

[0003] At present, when producing 3D glasses, first, a rectangular blank polarizer is placed under a laser cutting machine. The polarization direction of the polarizer is marked on the rectangular polarizer. Then, the staff places it at a suitable angle according to the marked polarization direction on the polarizer, and then uses the laser cutting machine to cut out the polarizer with the lens contour on the blank polarizer, and then installs the cut polarizer on the 3D glasses.

[0004] It is found in the production process of current 3D glasses that when placing and cutting the blank polarizer only relying on the staff to observe the marked angle on the polarizer, after the polarizer is placed, there is a lack of a device for fine-tuning the polarization direction of the polarizer. Therefore, after the cut polarizer is installed on the 3D glasses, there is a slight deviation in the polarization direction, which leads to a poor experience when people use the 3D glasses.

[0005] In the prior art, Patent CN 214374359 U discloses a polarization direction adjustment device in visual inspection. Although it can fine-tune the polarization direction of the polarizer according to the actual situation, it is adjusted after the polarizer is installed. In the field of 3D glasses, due to the limitation of the 3D glasses frame, for example, for 3D glasses with an elliptical lens shape, when the polarizer is cut into an elliptical contour and installed, it is impossible to rotate and adjust the polarization direction. Therefore, a device that can fine-tune the polarization direction of the polarizer when cutting the lens blank of 3D glasses is needed. Summary of the Invention

[0041] The following will specifically describe the preferred embodiments of the present invention with reference to the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present invention to explain the principles of the present invention, and are not used to limit the scope of the present invention.

[0043] The spectacle lens processing device 100 provided by the present invention, before cutting the lens to be cut (polarizer), first moves the adjustment seat 31 to the adjustment position 1a, then mounts the polarizer on the adjustment seat 31, turns on the projection unit 21, and then rotates the adjustment seat 31 until the imaging through the polarizer by the projection unit 21 is the clearest. At this time, the placement angle of the polarizer has been adjusted to the preset angle. Finally, the adjustment seat 31 is moved to the cutting position 1b to cut a polarizing lens suitable for the frame contour on the polarizer through the cutting unit 41. In this way, when cutting the lens blank of the 3D glasses, the polarization direction of the polarizer is finely adjusted, so that while the polarizing lens fits the contour of the frame, the imaging effect of the 3D glasses is ensured, enabling users to obtain a better experience.

[0044] It should be noted that the preset angle of the lens to be cut is the angle of rotation when it rotates from the initial position on the adjustment seat 31 until the clearest imaging is formed after passing through the projection unit 21. And in this embodiment, the projection unit 21 is a projector, and the cutting unit 41 is a laser cutting machine. In addition, in the attached drawing example, the up and down directions are shown by F.

[0045] Furthermore, the adjustment structure 3 further includes a base 32 and a translation driving assembly 33; the base 32 is arranged on the workbench 1 and moves back and forth between the adjustment position 1a and the cutting position 1b. The base 32 is respectively provided with a guiding channel 32a and a driving threaded hole 32b, and both the guiding channel 32a and the driving threaded hole 32b extend along the moving direction of the base 32. The adjustment seat 31 is rotatably arranged on the base 32; the translation driving assembly 33 includes a guide rail 331 arranged on the workbench 1 and a translation driving part 332. The guide rail 331 extends from the adjustment position 1a to the cutting position 1b and passes through the guiding channel 32a. The driving shaft of the translation driving part 332 is connected with a driving lead screw 333. The driving lead screw 333 extends from the adjustment position 1a to the cutting position 1b and passes through the driving threaded hole 32b to drive the base 32 to move.

[0046] In this embodiment, by the operation of the translation driving part 332 and with the cooperation of the driving lead screw 333 and the driving threaded hole 32b, the base 32 is enabled to move between the adjustment position 1a and the cutting position 1b, and further the adjustment seat 31 has a moving stroke of approaching and departing from the cutting position 1b. The structure is simple and reliable. Specifically, two support plates 13 are arranged on the workbench 1 at intervals. The two support plates 13 sandwich the adjustment position 1a and the cutting position 1b in the middle, and two guide rails 331 are arranged between the two support plates 13. The base 32 is correspondingly provided with two guiding channels 32a. In addition, the translation driving part 332 is a driving motor.

[0047] Further, a shaft hole is provided on one side of the base 32 close to the adjustment base 31, and a rotation driving part 34 is also provided corresponding to the shaft hole. A driving gear 341 is provided on the driving shaft of the rotation driving part 34; the adjustment base 31 is provided with a rotating shaft 311 corresponding to the shaft hole. The rotating shaft 311 is rotatably arranged in the shaft hole, and a transmission gear 312 is provided thereon. The transmission gear 312 meshes with the driving gear 341 to drive the adjustment base 31 to rotate when the driving shaft of the rotation driving part 34 rotates. In this solution, when the driving shaft of the rotation driving part 34 rotates, it drives the driving gear 341 to rotate, and then drives the transmission gear 312 to rotate, so as to realize the corresponding rotation of the adjustment base 31. Specifically, in this embodiment, the driving gear 341 and the transmission gear are set as bevel gears to save space. In addition, the rotation driving part 34 is also set in the form of a driving motor.

[0048] To prevent the polarizer from accidentally moving during the cutting of the cutting part 41, in this embodiment, please refer to Figure 4 and Figure 5 , the adjustment structure 3 further includes a clamping assembly 35. The clamping assembly 35 includes a clamping seat 351 and a pressing screw 352; the clamping seat 351 is arranged on the adjustment base 31 and is recessed with a clamping groove 351a with an open side in the horizontal direction. The clamping seat 351 is also provided with a pressing threaded hole communicating with the clamping groove 351a in the up-down direction; the pressing screw 352 is arranged in the pressing threaded hole, and a clamping gap 352a for clamping the lens to be cut is formed between the pressing screw 352 and the bottom wall of the clamping groove 351a. In this way, when installing the polarizer, first place the side end of the polarizer between the pressing screw 352 and the bottom wall of the clamping groove 351a, and then tighten the pressing screw 352 to clamp the polarizer, so as to avoid the accidental movement of the polarizer during the process of moving the adjustment base 31, and also avoid the accidental movement of the polarizer during the cutting of the cutting part 41, thereby improving the cutting accuracy.

[0049] It should be noted that, in this embodiment, there are a plurality of pressing threaded holes, and the plurality of pressing threaded holes are arranged at intervals along the extending direction of the clamping groove 351a. Correspondingly, there are also a plurality of pressing seat rods. In addition, a rubber pad is provided at one end of each pressing screw 352 extending into the clamping groove 351a to avoid damaging the polarizer.

[0050] Further, there are two clamping assemblies 35, and the two clamping assemblies 35 are arranged at intervals along the length or width direction of the adjustment base 31. Among them, the open side of each clamping groove 351a is located on one side of the corresponding clamping seat 351 close to the other clamping seat 351. In this way, the opposite ends of the polarizer can be clamped by the two clamping assemblies 35, making the clamping of the polarizer more stable.

[0051] Further, to improve the flexibility of the device, in this embodiment, at least one clamping seat 351 is movably arranged to have a moving stroke of approaching and departing from the other clamping seat 351, so that the distance between the two clamping seats 351 is adjustable. In this way, the distance between the two clamping seats 351 can be correspondingly adjusted to clamp polarizer blanks of different sizes, improving versatility.

[0052] Specifically, in this embodiment, the adjustment seat 31 is recessed with two avoidance grooves 31a corresponding to the two clamping seats 351, and a through hole communicating the two avoidance grooves 31a is also penetrated along the arrangement direction of the two clamping seats 351. A slide rail 313 is convexly provided on the side wall of each avoidance groove 31a; each clamping seat 351 is penetrated with a sliding groove corresponding to the slide rail 313 and a clamping threaded hole corresponding to the through hole, and the rotation directions of the two clamping threaded holes are opposite. Among them, the slide rail 313 is penetrated through the sliding groove; the adjustment structure 3 further includes a clamping screw 36, and the clamping screw 36 is penetrated through the through hole and each clamping threaded hole, and the thread rotation directions at both ends of the clamping screw 36 correspond to the two clamping threaded holes. In this solution, by rotating the clamping screw 36 to drive the two clamping seats 351 to approach or depart from each other, the distance between the two clamping seats 351 is adjusted, and the structure is simple and reliable and the operation is convenient.

[0053] Further, the clamping seat 351 is located on the upper end surface of the adjustment seat 31, and the clamping groove 351a is spaced from the adjustment seat 31 in the up-down direction; a display cloth 314 is provided on the upper end surface of the adjustment seat 31 corresponding to the projection part 21, and the display cloth 314 is used to receive the imaging of the lens to be cut. That is, in this embodiment, when the polarizer is clamped by the clamping seat 351, it is spaced from the upper end surface of the adjustment seat 31 in the up-down direction and corresponds to the display cloth 314. Thus, the image projected by the projection part 21 can pass through the polarizer and fall on the display cloth 314, which is convenient for the operator to view and makes the overall structure more compact.

[0054] Furthermore, to prevent the debris generated during the cutting by the cutting part 41 from affecting the use of the display cloth 314, in this embodiment, please refer to Figure 4 and Figure 6, the adjustment base 31 is recessed with a socket hole 31b beside the display cloth 314; the adjustment structure 3 further includes a protective cover plate 37, and the protective cover plate 37 is used to cover the upper side of the display cloth 314 when the cutting part 41 cuts the lens to be cut. Among them, the protective cover plate 37 is provided with a plug rod 371 corresponding to the socket hole 31b, and the plug rod 371 is inserted into the socket hole 31b. In this way, after the polarization angle is adjusted, the plug rod 371 is inserted into the socket hole 31b, so that the protective cover plate 37 covers the upper side of the display cloth 314 to prevent the debris generated during cutting from damaging the display cloth 314. Specifically, in this embodiment, there are multiple socket holes 31b, and the multiple socket holes 31b are arranged at intervals on the periphery of the display cloth 314, and the corresponding plug rods 371 are also multiple. And the upper end surface of the protective cover plate 37 is also provided with a high-temperature resistant coating.

[0055] In addition, in this embodiment, an air gun 5 is further provided on the workbench 1 corresponding to the cutting position 1b. The air pipe of the air gun 5 is connected to an external air pump. When it is necessary to clean the dust on the display cloth 314, the air gun 5 is aligned with the display cloth 314, and the air flow can blow the dust on the display cloth 314 off, which is convenient for cleaning the dust on the display cloth 314.
