Description

Technical Field

[0001] The utility model relates to the technical field of polarized lens processing, in particular to a pressing tool used for curing polarized lenses. Background Art

[0002] Polarized lenses are made based on the principle of light polarization. They are mainly used to eliminate and filter out scattered light in the light beam, so that the light can enter the eye's visual image along the correct transmission axis, thereby making the field of vision clear and natural. Polarized lenses need to be fixed with the help of a press during the fixing process to prevent the lenses from expanding.

[0003] After searching, the patent number CN210501027U discloses a press for secondary curing of polarized lenses. The press applies pressure to the upper surface of the polarized lens through the cooperation of a pressure block and a carrier to eliminate internal stress, so that the upper surface of the polarized lens will not shrink due to the shrinkage of the polarizing film during the secondary curing process.

[0004] However, the above-mentioned press needs to be manually pushed out of the lens from the carrier after use, and the operator's contact with the lens is likely to cause fingerprint stains on the lens, thereby reducing the quality of lens preparation. Utility Model Content

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a pressing tool for curing polarized lenses.

[0026] The utility model provides Figure 1-4 The press shown in the figure is used for curing polarized lenses and includes a press 1 and a carrier 2 matched with the press 1. A support frame 3 is sleeved on the lower end of the outer wall of the carrier 2. Cross bars 4 are rotatably penetrated on both sides of the support frame 3. The cross bars 4 are fixedly connected to the carrier 2. A sleeve plate 5 is fixedly provided on the upper end of the outer wall of the press 1. A through groove is opened on the upper end of the side of the support frame 3. A driving screw 6 is rotatably penetrated on the top of the through groove. The driving screw 6 is threadedly penetrated inside the sleeve plate 5. A torsion spring 15 is sleeved on the rear end of the cross bar 4. The two ends of the torsion spring 15 are respectively fixedly connected to the cross bar 4 and the support frame 3.

[0027] Before the polarized lens is cured, the lens is placed inside the carrier 2, and the press 1 is inserted into the carrier 2 to cure the lens so that it is positioned. After the lens is cured, the drive screw 6 can be rotated so that the drive screw 6 drives the sleeve 5 to move upward, and the press 1 is pulled out from the carrier 2. Under the setting of the support frame 3, the cross bar 4 drives the carrier 2 to flip, so that the lens inside the carrier 2 can fall down autonomously to complete the unloading, reducing the contact with the operator. When the cross bar 4 rotates, the torsion spring 15 is twisted. When the lens is unloaded, the carrier 2 can rotate back to its original position under the torsion of the torsion spring 15.

[0028] In order to be able to drive the carrier 2 to flip and unload after the press 1 is separated from the carrier 2, as shown in FIG. Figure 1-2 As shown, a flipping and unloading mechanism is provided between the sleeve plate 5 and the cross bar 4, and the flipping and unloading mechanism includes a circular gear 7. A vertical plate 8 is fixedly provided at the bottom of the sleeve plate 5, and a plurality of support rods 9 arranged at intervals are fixedly provided on the outer wall of the vertical plate 8. A push plate 10 is rotatably sleeved on the rod wall of the support rod 9, and a limit plate 11 is contacted at the bottom of the push plate 10, and the limit plate 11 is fixedly connected to the vertical plate 8. The circular gear 7 is fixedly sleeved on the cross bar 4 and is arranged in cooperation with the plurality of push plates 10.

[0029] During the separation process of the press 1 and the carrier 2, the vertical plate 8 moves with the sleeve plate 5. When the press 1 is pulled out from the inside of the carrier 2, multiple push plates 10 start to push the circular gear 7 with the support of the limit plate 11, so that the circular gear 7 drives the cross bar 4 to rotate. At this time, the cross bar 4 drives the carrier 2 to flip over. When the press 1 and the carrier 2 are plugged in and connected, since the push plate 10 can rotate around the support rod 9, the circular gear 7 cannot be pushed, so that the press 1 and the carrier 2 can be stably connected and matched.

[0030] In order to ensure the stable connection between the pressing tool 1 and the carrier 2 during the curing process, Figure 1 and Figure 3 As shown, a rotating block 12 is fixedly provided at the bottom of the driving screw rod 6, a rotating groove for cooperating with the rotating block 12 is opened on the inner wall of the through groove, a groove is opened on the outer wall of the rotating block 12, a spring 13 is fixedly provided on the inner wall of the groove, an insert plate 14 is slidably passed through the inside of the groove, the insert plate 14 is an L-shaped insert plate, the insert plate 14 is fixedly connected to the spring 13, and a positioning hole for cooperating with the insert plate 14 is opened inside the rotating groove.

[0031] When the driving screw 6 needs to be rotated, the plug plate 14 can be pulled out from the positioning hole and the spring 13 can be squeezed. At this time, the rotating block 12 rotates in the rotating groove to drive the driving screw 6 to rotate. When the pressing tool 1 is connected to the carrier 2, the plug plate 14 can be loosened, and the plug plate 14 can be inserted into the positioning hole under the rebound of the spring 13 to fix the position of the driving screw 6, so as to avoid the driving screw 6 from being accidentally rotated and affecting the curing stability.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
