Description

Clamp for lens spectrum test Technical Field The utility model relates to the technical field of clamps, in particular to a clamp for testing a lens spectrum. Background The lens spectrum test is a key method for evaluating the optical performance of the lens by analyzing the transmission, reflection or absorption characteristics of the lens to light with different wavelengths, and the lens is required to be fixed on a clamp when the lens is subjected to spectrum test, so that the lens is prevented from moving randomly, and the verticality of the lens and test light is ensured; the utility model patent with the Chinese patent application number of CN202421280701.0 discloses a spectrum test lens clamp which comprises a substrate, a positioning part, a clamping part and a clamping part, wherein the test lens is placed on the substrate, a chute is formed in the substrate, the positioning part is used for positioning the test lens, the positioning part comprises a positioning block, the positioning block can slide relative to the substrate, the clamping part is used for clamping and fixing the test lens, the clamping part comprises a fixing piece, an elastic piece and a clamping piece, the fixing piece is fixedly arranged on the substrate, the first end of the elastic piece is connected with the fixing piece, the second end of the elastic piece is connected with the clamping piece, and the clamping piece slides in the chute. The lens testing device has the advantages that the lens testing device is positioned through the positioning part, the lens is clamped and fixed through the clamping piece, the clamping and fixing effect on the lens testing device is guaranteed, when the lens testing device is used for testing, the lens testing device only needs to be tightly attached to the lens testing device under the condition that the substrate is perpendicular to the testing light, and therefore the lens with a certain size range and thickness can be precisely measured. The fixture can clamp and fix lenses with different sizes and thicknesses, but when the lenses are fixed, the fixture needs manual operation of a worker, the operation process is complex, the fixing efficiency of the lenses is reduced, and only one lens can be fixed at a time for detection, so that the detection efficiency is reduced. Disclosure of utility model The utility model discloses a clamp for testing a lens spectrum, which solves the problems that a lens is manually fixed, the operation process is complex, the fixing efficiency is low, and only one lens can be fixed at a time for detection. In order to solve the technical problems, the utility model adopts the following technical scheme: A clamp for testing optical spectrum of lenses comprises a connecting frame, wherein a bearing plate capable of moving forwards and backwards is arranged in the connecting frame, two moving bars capable of being mutually closed are connected to the bearing plate in a sliding mode, an electric telescopic rod used for driving the moving bars is arranged on the bearing plate, a group of through holes located between the two moving bars are formed in the bearing plate, a group of abutting plates capable of moving forwards and backwards are arranged on opposite faces of the two moving bars, and an automatic telescopic rod used for driving the abutting plates is arranged on the moving bars. Compared with the prior art, the utility model has the following beneficial effects: Placing the lenses on the bearing plate, enabling the axial center of the lenses to correspond to the axial center of the through hole, starting the electric telescopic rod after the placement of one group of lenses is completed, enabling the two moving strips to be close to each other, propping against two sides of the lenses, then starting the two first automatic telescopic rods, enabling the two groups of propping plates to move, propping against the front side and the rear side of one group of lenses respectively, and finishing the fixation of the lenses; then, the optical spectrum test is carried out on the lenses, when one lens is tested, the bearing plate can be moved, and after the next lens is moved to the test position, the test is carried out on the lens; the utility model can rapidly fix a group of lenses, so that the group of lenses can be subjected to spectrum test in sequence, and the fixing efficiency and the detection efficiency of the lenses are improved.
