Description

Technical Field

[0001] The utility model relates to the technical field of flipping mechanisms, and particularly relates to a wafer lens flipping mechanism. Background Art

[0002] The lens assembly consists of a wafer lens X, a housing Y, and a locking ring Z; the wafer lens X needs to be installed into the interior of the housing Y in a specific installation direction; however, after the wafer lens X is cut, the convex surface faces upward. But when assembling it into the housing Y, the convex surface needs to face downward.

[0003] Therefore, before loading the wafer lens X, the wafer lens X is flipped by 180°, and then grabbed. Currently, the flipping of the wafer lens X is achieved by clamping the side surface of the wafer lens X with a rotating clamp finger cylinder and flipping it. Although this clamping form of rotating structure is simple and requires a small layout space, when using this clamping structure, it is necessary to control the clamping force well. If the clamping force is too large, it is easy to scratch the side surface of the lens, resulting in defective products and affecting the yield of the products. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a wafer lens flipping mechanism in view of the defects and deficiencies of the prior art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A wafer lens flipping mechanism of the utility model includes a swing rod and a sliding plate; a rotating component and a nozzle fixing plate are fixed on the sliding plate; the swing rod is connected to the rotating component;

[0007] The rotating component is used to drive the swing rod to swing; lens nozzles are fixed on both the swing rod and the nozzle fixing plate; the lens nozzle on the swing rod is the first nozzle; the lens nozzle on the nozzle fixing plate is the second nozzle; the second nozzle is arranged on the movement path of the first nozzle.

[0008] Further, the rotating component is any one of a rotating cylinder and a motor.

[0009] Further, a plurality of strip holes are provided on the nozzle fixing plate; the strip holes are arranged in parallel; a plurality of threaded holes are provided on the sliding plate; a head bolt is arranged in each strip hole; the head bolt passes through the strip hole and is threadedly connected with the threaded hole; the head of the head bolt fixes the nozzle fixing plate on the sliding plate.

[0010] Further, it further includes a flipping fixing base; the sliding plate is slidably connected to the flipping fixing base; a differential head is connected between the sliding plate and the flipping fixing base.

[0011] After adopting the above structure, the beneficial effects of the present utility model are as follows: When using the present utility model, after the wafer lens waiting to be flipped is placed on the first suction nozzle on the swing rod, the wafer lens is adsorbed and fixed by the first suction nozzle, and then the rotating assembly drives the swing rod to rotate, so that the first suction nozzle and the wafer lens are flipped together by 180 degrees; after one end of the wafer lens away from the first suction nozzle fits onto the second suction nozzle, the second suction nozzle adsorbs the wafer lens, and the first suction nozzle releases the wafer lens, waiting for the loading and unloading mechanism to pick up the material; in this structure, through the cooperation of the flipping structure and the two suction nozzles for adsorption and placement, the damage to the surface of the wafer lens can be reduced, and the yield of the product can be guaranteed.

[0018] The present utility model will be further described below in conjunction with the drawings.

[0019] As Figures 1 to 2 shown, a wafer lens flipping mechanism of the present utility model includes a swing rod B3 and a sliding plate B7; a rotating assembly B4 and a suction nozzle fixing plate B6 are fixed on the sliding plate B7; the swing rod B3 is connected to the rotating assembly B4;

[0020] The rotating assembly B4 is used to drive the swing rod B3 to swing; lens suction nozzles B1 are fixed on both the swing rod B3 and the suction nozzle fixing plate B6; the lens suction nozzle B1 on the swing rod B3 is the first suction nozzle; the lens suction nozzle B1 on the suction nozzle fixing plate B6 is the second suction nozzle; the second suction nozzle is arranged on the movement path of the first suction nozzle;

[0021] The lens suction nozzle B1 has no essential difference from the existing suction nozzle mechanism, so it will not be elaborated here; the position for adsorbing the product in the lens suction nozzle B1 is made of a cylindrical silica gel material, which can reduce the impact on the wafer lens X;

[0022] After the wafer lens X waiting to be flipped is placed on the first suction nozzle on the swing rod B3, the wafer lens X is adsorbed and fixed by the first suction nozzle. Then, the rotating assembly B4 drives the swing rod B3 to rotate, so that the first suction nozzle and the wafer lens X are flipped together by 180 degrees. After one end of the wafer lens X away from the first suction nozzle fits onto the second suction nozzle, the second suction nozzle adsorbs the wafer lens X, and the first suction nozzle releases the wafer lens X, waiting for the pick-and-place mechanism to pick up the material. In this structure, through the cooperation of the flipping structure and the two suction nozzles for adsorption and placement, the damage to the surface of the wafer lens X can be reduced, and the yield of the product can be guaranteed.

[0023] As a preferred embodiment of the present invention, the rotating assembly B4 is any one of a rotating cylinder and a motor.

[0025] After loosening the leading bolts, the suction nozzle fixing plate B6 can slide along the length direction of the strip hole B601 to adjust the positions of the suction nozzle fixing plate B6 and the second suction nozzle; so that after the first suction nozzle is flipped in place, the first suction nozzle, the second suction nozzle, and the wafer lens X are coaxial; preventing the wafer lens X from falling when being transferred from the first suction nozzle to the second suction nozzle.

[0026] As a preferred embodiment of the present invention, it further includes a flipping fixing seat B2; the sliding plate B7 is slidably connected to the flipping fixing seat B2; a differential head B5 is connected between the sliding plate B7 and the flipping fixing seat B2; the differential head B5 has no essential difference from the prior art, so it will not be elaborated here; the two ends of the differential head B5 are respectively connected to the flipping fixing seat B2 and the sliding plate B7; the differential head B5 can perform telescopic movement, and by rotating the differential head B5, the overall position of the sliding plate B7 on the flipping fixing seat B2 can be adjusted to synchronously align the positions of the two lens suction nozzles B1 with the pick-and-place mechanism.

[0027] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
