DETAILED DESCRIPTION

[0032] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0033] Example 1

[0034] An optical lens fastening device, referring to Figure 1 As shown, it includes a base 1, a support frame 2, a clamping block 3, a rubber pad 4, a pushing component 5 and an anti-warping component 6. The support frame 2 is welded to the middle of the base 1, and clamping blocks 3 are slidably installed on the front, back, left and right sides of the upper part of the support frame 2. The clamping blocks 3 can clamp the lenses, and rubber pads 4 are installed on the inner sides of the upper parts of the clamping blocks 3. A pushing component 5 is provided between the support frame 2 and the clamping block 3. The pushing component 5 can move the clamping block 3 to clamp the lenses. An anti-warping component 6 is provided between the pushing component 5 and the support frame 2. The anti-warping component 6 prevents the lenses from warping and keeps the lenses level.

[0035] Reference Figure 2 As shown, the pushing assembly 5 includes a first spring 51, a first connecting rod 52, a second connecting rod 53 and a second spring 54. The first connecting rod 52 is slidably installed on the front, back, left and right sides of the upper part of the support frame 2. The first connecting rod 52 is on the inner side of the clamping block 3. The first connecting rod 52 is connected to the adjacent clamping block 3 with the first spring 51. The second connecting rod 53 is slidably installed in the middle part of the support frame 2. After the second connecting rod 53 moves, the clamping block 3 can be moved. A second spring 54 is connected between the bottom of the second connecting rod 53 and the base 1. The second connecting rod 53 and the first connecting rod 52 are both slidably connected.

[0036] Reference Figure 2As shown, an anti-sliding block 11 is also included, and the anti-sliding block 11 is welded to the right front side of the second connecting rod 53 .

[0037] Reference Figure 3-Figure 5 As shown, the anti-warping component 6 includes a first contact rod 61, a third spring 62, a third connecting rod 63, a second contact rod 64, a fourth spring 65 and a spring 66. The third connecting rod 63 is rotatably installed on the four sides of the upper front, back, left and right of the support frame 2. The second contact rod 64 is slidably installed on the upper part of the third connecting rod 63. The second contact rod 64 can resist the top of the lens. The second contact rod 64 is connected to the adjacent third connecting rod 63 by a fourth spring 65. The third connecting rod 63 is connected to the support frame 2 by a spring 66. The first contact rod 61 is slidably installed on the four sides of the upper front, back, left and right of the support frame 2. The first contact rod 61 is connected to the support frame 2 by two third springs 62. The first contact rod 61 is in contact with the adjacent third connecting rod 63 and the first connecting rod 52.

[0038] The staff can place the lens in the middle of the support frame 2, and then step on the second connecting rod 53 to move downward through the anti-sliding block 11, the second spring 54 is compressed, the second connecting rod 53 moves downward to drive the first connecting rod 52 to move inward, the first connecting rod 52 moves inward to drive the clamping block 3 and the rubber pad 4 to move inward through the first spring 51, and the clamping block 3 moves inward to contact the lens and then clamps the lens. Under the action of the rubber pad 4, the lens can be prevented from being damaged. When the lens is clamped and the anti-sliding block 11 continues to move downward, the clamping block 3 cannot Continue to move inward, so that the first spring 51 will be stretched, so that the first spring 51 plays a buffering role to prevent the lens from being cracked due to excessive stepping. Initially, the spring 66 is in a deformed state, and the third spring 62 is in a compressed state. The first connecting rod 52 moves inward and no longer resists the first contact rod 61. Under the action of the third spring 62, the first contact rod 61 moves inward and no longer resists the third connecting rod 63. Under the action of the spring 66, the third connecting rod 63 drives the second contact rod 64 and the fourth spring 65 to rotate inward. When the second contact rod 64 and the fourth spring 65 rotate inward, the third connecting rod 63 drives the second contact rod 64 and the fourth spring 65 to rotate inward. When the rod 64 rotates to contact the lens and the third connecting rod 63 continues to rotate, the second contact rod 64 moves on the third connecting rod 63, the fourth spring 65 is stretched, and the second contact rod 64 will resist the top of the lens, so that the lens can be firmly fixed, so that it is convenient for people to process the lens. After the lens is processed, the anti-sliding block 11 is no longer stepped on. Under the action of the second spring 54, the anti-sliding block 11 and the second connecting rod 53 move upward and reset. The second connecting rod 53 moves upward and drives the first connecting rod 52 to move outward and reset. At the same time, under the action of the first spring 51, the clamping block 3 moves and resets relative to the first connecting rod 52. The first connecting rod 52 moves outward to contact the first contact rod 61 and then continues to move, which will cause the first contact rod 61 to move outward. The third spring 62 is compressed, and the first contact rod 61 moves outward to drive the third connecting rod 63, the second contact rod 64 and the fourth spring 65 to rotate and reset outward. At the same time, under the action of the fourth spring 65, the second contact rod 64 moves and resets on the third connecting rod 63, and the staff can remove the processed lens.

[0039] Example 2

[0040] Based on Example 1, Figure 1 and Figure 6 As shown, it also includes a clamping component 7, which can clamp the second connecting rod 53. The clamping component 7 includes a clamping rod 71 and a fifth spring 72. A first through hole 73 is opened on the right front side of the second connecting rod 53. A clamping rod 71 is slidably installed on the right front side of the base 1. The clamping rod 71 can clamp the second connecting rod 53. A fifth spring 72 is connected between the clamping rod 71 and the base 1.

[0041] When the second connecting rod 53 moves downward until it contacts the card rod 71 and continues to move, the card rod 71 will move backward and the fifth spring 72 will be compressed. After the card rod 71 passes over the first through hole 73, the card rod 71 moves forward under the action of the fifth spring 72. The card rod 71 moves forward and will be above the second connecting rod 53. In this way, the second connecting rod 53 can be fixed by the card rod 71. In this way, there is no need to step on the anti-sliding block 11 all the time when processing the lens. When the second connecting rod 53 needs to be moved upward and reset, the card rod 71 can be pushed to move backward and no longer clamp the second connecting rod 53. The fifth spring 72 is compressed, and the second connecting rod 53 can move upward and reset. The card rod 71 is released, and the card rod 71 moves forward and resets under the action of the fifth spring 72.

[0042] Reference Figure 1 and Figure 7 As shown, a buffer assembly 8 is also included. The buffer assembly 8 can slow down the rotation speed of the third connecting rod 63. The buffer assembly 8 includes a guide rod 81, a third contact rod 82 and a sixth spring 83. A group of guide rods 81 are slidably installed on the four sides of the top of the support frame 2, front, back, left and right. The number of guide rods 81 in each group is 2. The tops of each group of guide rods 81 are connected with third contact rods 82. The bottoms of the third contact rods 82 are connected to the support frame 2 with two sixth springs 83. The sixth spring 83 can play a buffering role, and the third connecting rod 63 will contact the third contact rod 82.

[0043] After the third connecting rod 63 rotates and contacts the third contact rod 82 and continues to rotate, the third contact rod 82 will drive the guide rod 81 to move downward, and the sixth spring 83 will be compressed. Under the reaction of the sixth spring 83, the speed of the third connecting rod 63 will be slowed down, so as to avoid the second contact rod 64 directly hitting the lens and breaking the lens. When the third connecting rod 63 rotates and resets and no longer resists the third contact rod 82, the third contact rod 82 and the guide rod 81 move upward and reset under the action of the sixth spring 83.

[0044] Reference Figure 1 , Figure 8 , Fig. 9 and Fig.10 As shown, it also includes an anti-drop component 9, which can absorb the lens to prevent it from falling. The anti-drop component 9 includes a suction cup 91, a piston rod 93 and a seventh spring 94. A suction cup 91 is installed on the upper side of the middle part of the support frame 2. The suction cup 91 can absorb the lens to prevent it from falling. A second through hole 92 is opened in the middle of the suction cup 91, and a piston rod 93 is slidably installed in the second through hole 92. The piston rod 93 is in contact with the second connecting rod 53, and the seventh spring 94 is connected between the piston rod 93 and the suction cup 91.

[0045] Initially, the seventh spring 94 is stretched, and the second connecting rod 53 moves downward and no longer resists the piston rod 93. Under the action of the seventh spring 94, the piston rod 93 moves downward. The piston rod 93 moves downward to evacuate air, thereby sucking the lens tightly through the suction cup 91. In this way, the lens can be prevented from shifting during the process of fixing the lens, thereby improving the placement stability of the lens. When the second connecting rod 53 moves upward, it drives the piston rod 93 upward, and the seventh spring 94 is stretched. The piston rod 93 moves upward to push out the gas so that the suction cup 91 no longer sucks the lens tightly.

[0046] Reference Figure 1 , Fig.11 and Fig.12 As shown, a water spray assembly 10 is also included, and the water spray assembly 10 includes a nozzle 101, a water pipe 102, a ball valve 103 and a handle 104. Two nozzles 101 are welded on the upper middle side of the support frame 2, and the water pipe 102 is connected between the nozzles 101. The ball valve 103 is rotatably installed on the right part of the water pipe 102, and the handle 104 is welded on the top of the ball valve 103.

[0047] The staff can also connect the external pipe to the water pipe 102 and let water flow through it, then turn the handle 104 to drive the ball valve 103 to rotate so as not to block the water pipe 102, and the water will be sprayed out through the water pipe 102 and the nozzle 101, so that it can be sprayed on the lens. The lens is wetted and can be better adsorbed by the suction cup 91. When the suction cup 91 is adsorbed, the handle 104 can be turned in the opposite direction to drive the ball valve 103 to rotate and block the water pipe 102, and then the water can be stopped and the external pipe can be removed.
