Description

Technical Field

[0001] The utility model relates to the technical field of optical filter detection, in particular to an optical filter microscopic detection device. Background Art

[0002] There are many types of optical filters, among which the infrared cutoff filter is an optical filter used to filter the infrared band. In terms of appearance, the infrared cutoff filter must ensure a smooth surface. Because it is widely used in the field of cameras, tiny cracks, pitting, scratches, and dirt will be magnified, seriously affecting the imaging quality. In terms of performance, the infrared cutoff filter must ensure that it cannot be penetrated by infrared rays.

[0003] The publication (announcement) number is CN209858182U, which discloses a filter microscopic detection device, including: a detection fixture and a microscope arranged above the detection fixture; the detection fixture is provided with a pure water storage tank designed according to the product shape specifications; the detection fixture is provided with an injection channel and a liquid extraction channel, each of which is used to be connected to the injection device and the liquid extraction device at one end, and the other end of the injection channel and the liquid extraction channel is connected to the pure water storage tank. The structure design of the utility model is reasonable and ingenious. Through the setting of the pure water storage tank and the microscope, the appearance of the infrared cut-off filter can be detected; through the setting of the high-wavelength red light emitter and the product support block, the performance of the infrared cut-off filter can be detected; in addition, the setting of the injection channel and the liquid extraction channel is convenient to ensure the water level balance of the pure water in the pure water storage tank, and the pure water in the pure water storage tank can be replaced in time through the injection channel and the liquid extraction channel to ensure the accuracy of the detection.

[0004] Although the above scheme improves the detection effect through pure water and red light emitter, the microscope lacks positioning adjustment through slide rail translation and is prone to shaking and shifting. The positioning bolts must be repeatedly disassembled and assembled when the microscope is raised and lowered on the guide column. The equipment raising and lowering adjustment operation is troublesome and laborious. Therefore, we propose a filter microscopic detection device. Utility Model Content

[0005] The main purpose of the utility model is to provide a filter microscopic detection device, which solves the problem that the microscope is prone to shaking and shifting due to lack of positioning adjustment when translated by a slide rail by means of a first adjustment unit.

[0006] To solve the above technical problems, the utility model is implemented by the following technical solutions: a filter microscopic detection device, comprising a carrier plate and a microscope, and further comprising: a first adjustment unit and a second adjustment unit arranged between the carrier plate and the microscope, and an object placement component arranged on the carrier plate;

[0007] The first adjustment unit includes a carrier box, a transverse screw rod, a support block and a rectangular box, wherein the carrier box is fixedly arranged on the end surface of the carrier plate, and a strip-shaped through groove is opened at the center of the top surface of the carrier box, the transverse screw rod is movably arranged on the inner wall of one end of the carrier box, the support block is in a "convex" shape and is threadedly connected to the transverse screw rod, and the support block is located on the strip-shaped through groove, and the rectangular boxes are provided with two and symmetrically fixed on the top surfaces of both ends of the support block, and a first rotating disk is fixedly arranged on one end of the transverse screw rod that movably extends to the outside of the carrier box;

[0008] The second adjustment unit includes a vertical screw rod, a supporting cross plate, a supporting block and a limiting plug block. The vertical screw rod is movably arranged on the inner wall of one of the rectangular boxes, the supporting cross plate is movably arranged between the two rectangular boxes and is threadedly connected to the vertical screw rod, the supporting block is fixedly arranged at the center of one side of the supporting cross plate, a rectangular notch is provided on the top surface of one end of the supporting block, the limiting plug block is "L"-shaped and is movably arranged on the rectangular notch, and the end face of the limiting plug block is fixedly connected to the surface of one side of the microscope, and a second turntable is fixedly arranged on one end of the vertical screw rod that movably extends to the outside of the rectangular box.

[0009] Preferably, the first adjustment unit further comprises a transverse guide rod, which is fixedly arranged on the inner wall of the other end of the carrying box and movably passes through the other supporting block.

[0010] Preferably, the second adjustment unit further comprises a vertical guide rod, which is fixedly arranged on the inner wall of another rectangular box and movably penetrates the supporting horizontal plate.

[0012] Preferably, a lifting handle is fixedly provided on the top surface of the pure water storage box.

[0013] Preferably, the microscope is provided with a high-wavelength red light emitter, which is tilted and has its output end facing the placement groove. The tilted high-wavelength red light emitter makes the high-wavelength red light obliquely emitted toward the infrared cut-off filter. If the performance of the infrared cut-off filter is unsatisfactory, the high-wavelength red light will penetrate the infrared cut-off filter and refract in pure water at a larger angle, making it easier to observe.

[0014] Preferably, supporting feet are fixedly provided at the corners of the bottom surface of the carrier plate, and a counterweight is fixedly provided on the bottom surface of one end of the carrier plate away from the carrying box.

The vertical guide rod can cooperate with the support cross plate to slide and rise and fall and provide auxiliary support for it. The equipment lifting and adjustment operation is simple and labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS
