Description

Technical Field

[0001] This utility model relates to the field of optical lens technology, and in particular to a positioning fixture for bonding optical lenses. Background Technology

[0002] Positioning fixtures for optical lens bonding are tools specifically designed for positioning and fixing optical lenses during the bonding process. These fixtures play a crucial role in the production of optical lenses, ensuring that two or more lenses maintain precise relative positions during bonding, thereby guaranteeing the optical performance and quality of the final product.

[0003] In practical use, existing positioning fixtures require the use of suction tubes to confine optical lenses inside the fixture. However, when placing multiple sets of optical lenses, there is a situation where the placed optical lenses are subjected to impact forces, causing their positions to shift. When the suction tube is used for limiting, it is impossible to accurately position the optical lenses to the required positions. Therefore, a positioning fixture for bonding optical lenses is needed to ensure that the optical lenses are stably and accurately confined inside the fixture before the use of suction tubes.

[0030] Please see Figures 1-3 As shown, this embodiment is a positioning fixture for bonding optical lenses, comprising:

[0031] Placement components, including fixture body 11;

[0032] The mounting components include a fixing plate 23, which is located on top of the fixture body 11;

[0033] The limiting assembly includes a support plate 31, a movable column 32, a limiting hole 33, a limiting rod 34, and a connecting plate 35. The support plate 31 is fixed to the upper surface of the fixed plate 23. The movable column 32 is movably connected to the inside of the support plate 31. The limiting hole 33 is opened inside the movable column 32. Two sets of limiting holes 33 are opened inside one set of movable columns 32. The limiting rod 34 is inserted into the top limiting hole 33 and the inside of the support plate 31. The connecting plate 35 is fixed to the outer surface of the limiting rod 34.

[0034] The support plate 31 is used to install on the top of the fixed plate 23, thereby fixing the movable column 32 in the required position. By changing the position of the movable column 32, the position of the silicone block 38 can be changed. The limiting hole 33 is used to cooperate with the limiting rod 34, thereby fixing the silicone block 38 at the bottom of the movable column 32 at different heights. The connecting plate 35 is used to change the position of the limiting rod 34.

[0035] A spring 36 is fixed inside the support plate 31. The outer surface of the spring 36 is fixed to the outer surface of the connecting plate 35. A guide groove 37 is opened inside the movable column 32. The guide groove 37 is located at the top of the bottom limiting hole 33.

[0036] Spring 36 is used to provide elastic force so that the limiting rod 34 can be quickly reset when the connecting plate 35 is not under force. Guide groove 37 is used to understand the position of the bottom limiting hole 33 inside the support plate 31. Silicone block 38 is used to restrict the lens body 16 in the required position.

[0037] The placement assembly also includes a mounting slot 12, a support frame 13, a silicone pad 14, an air suction tube 15, and a lens body 16. The mounting slot 12 is formed inside the fixture body 11, the support frame 13 is fixed inside the mounting slot 12, the air suction tube 15 is fixed inside the support frame 13, the silicone pad 14 is fixed to the upper surface of the support frame 13, the lens body 16 is attached to the upper surface of the air suction tube 15, and the upper surface of the lens body 16 is attached to the lower surface of the silicone block 38.

[0038] The mounting slot 12 is used to place the lens body 16 inside the fixture body 11. The support frame 13 is used to receive and install the suction tube 15. The silicone pad 14 is used to fix the lens body 16 more stably and softly in the required position. By changing the air pressure inside the suction tube 15, the lens body 16 is fixed on the top of the silicone pad 14.

[0039] Working principle: When it is necessary to place the lens body 16 inside the fixture body 11, first place the lens body 16 into the mounting slot 12 and adjust the position of the lens body 16. Apply a pulling force to the connecting plate 35 to drive the limiting rod 34 out of the movable column 32. Apply a downward pressing force to the limiting rod 34 so that the silicone block 38 is attached to the surface of the lens body 16. Then release the force applied to the connecting plate 35. Under the elastic force of the spring 36, the limiting rod 34 will spring to the top limiting hole 33 and the support plate 31.

[0040] This step ensures that the optical lens is stably and precisely confined inside the fixture before using the suction tube 15.

[0041] Please see Figure 1 , Figure 2 and Figure 4 As shown, this embodiment, based on the above embodiment, also includes an installation component. The installation component includes a fixing frame 21, a fixing post 22, a fixing bracket 24, and a limiting post 25. The fixing frame 21 is fixed to the outer surfaces of both sides of the fixture body 11. The fixing post 22 is inserted into the interior of the fixing frame 21.

[0044] The guide plate 26 is used to change the position of the limiting post 25. By changing the state of the rotating post 27, the limiting post 25 is fixed in the desired position.

[0045] Magnet blocks 29 are fixed to the outer surfaces of the fixing frame 21 and the fixing bracket 24. The magnet blocks 29 at the fixing frame 21 are magnetically connected to the magnet posts 28.

[0046] By connecting the magnetic post 28 to the magnetic blocks 29 at different positions, the limiting post 25 can be fixed in different positions.

[0047] Working principle: When the limiting component is needed, first insert the fixing post 22 into the fixing frame 21, apply a pushing force to the guide plate 26 so that the limiting post 25 is inserted into the fixing frame 21, and then apply a flipping force to the rotating post 27 so that the magnet post 28 and the magnet block 29 are connected together.
