Description

Technical Field

[0001] This utility model relates to the field of infrared thermal imaging technology, specifically to an integrated infrared cooling detector and infrared lens assembly structure. Background Technology

[0002] In the utility model patent application CN 105093234 A, published on November 25, 2015, entitled "An Integrated Infrared Cooled Detector and Infrared Lens Assembly Structure with Single-Lens Co-optical Axis Output Laser Ranging Device," a laser ranging device includes a laser emitting part and a laser receiving part. The laser emitting part includes a laser emitting tube, a corner fiber tube, and a first objective lens arranged sequentially along the optical axis. A reflector is provided at the corner of the corner fiber tube, so that the laser is reflected to the first objective lens. The laser receiving part includes the first objective lens, a second objective lens co-optically with the first objective lens, and a laser receiver. The two objective lenses and the laser receiver are sequentially mounted on a sleeve along the optical axis. The emitting and receiving optical paths of the above-mentioned laser ranging device are angled and share the first objective lens, requiring only one measuring lens, making the structure simple and compact, small in size, light in weight, and low in maintenance costs. Moreover, the corner fiber tube greatly reduces the emitting area, minimizes the area of ​​blocked received light, minimizes received energy loss, and provides a wide measurement range and high accuracy.

[0003] Currently, the assembly of infrared cooled detectors with lenses / snap shutters requires the design and fabrication of many mating structural components for fixing within the housing. The assembly process is very complicated and cumbersome, and the separate assembly of various precision parts makes it very easy to produce assembly errors, leading to optical misalignment and various problems. Utility Model Content

[0004] The purpose of this invention is to provide an integrated infrared cooling detector and infrared lens assembly structure to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An integrated infrared cooled detector and infrared lens assembly structure is disclosed, wherein an infrared cooled detector and an infrared lens are slidably connected on a base; the base and the infrared cooled detector are connected through a first adjustment unit, and the base and the infrared lens are connected through a second adjustment unit.

[0007] Preferably, a first connecting seat is fixedly connected to the bottom of the infrared cooled detector, and a second connecting seat is provided below the infrared cooled detector. The first connecting seat, the second connecting seat, and the base are connected by a first adjustment unit.

[0008] Preferably, the first adjustment unit includes a first connector and a second connector, the first connector being used to connect the first connecting seat and the second connecting seat, and the second connector being used to connect the second connecting seat and the base.

[0009] Preferably, the first connector includes a plurality of first waist-shaped grooves formed on the first connector seat and a plurality of first limiting members fixedly connected to the second connector seat, wherein each first limiting member is provided in a one-to-one correspondence with each first waist-shaped groove.

[0010] Preferably, the second connector includes a plurality of second waist-shaped grooves formed on the second connector seat and a plurality of second limiting members fixedly connected to the base, with each second limiting member corresponding to each second waist-shaped groove.

[0011] Preferably, the infrared lens is provided with a shutter support, and the shutter support is connected to the base through a second adjustment unit.

[0012] Preferably, the second adjustment unit includes a plurality of third limiting members fixedly connected to the base, and a third waist-shaped groove formed on the shutter bracket, with each third waist-shaped groove corresponding to each third limiting member.

[0013] In the above technical solution, the integrated infrared cooling detector and infrared lens assembly structure provided by this utility model ensures the consistency of the optical axis by integrating various precision parts, and eliminates the need to process other redundant parts to fix the lens and shutter. The modularization of the internal core components facilitates production line installation and shipment. When installed in the outer casing, it is only necessary to fix the base in the threaded hole position in the casing, minimizing assembly errors. At the same time, the first connecting seat slides in the first waist-shaped groove on the second connecting seat of the first limiting member, realizing the optical axis adjustment function of the infrared cooling detector in all directions. This avoids the inability to adjust the optical axis and optical path after installation in the casing. Meanwhile, the shutter is directly fixed to the base, avoiding the problem of inconvenient fixation in the confined space of the casing, improving fixation efficiency, increasing product stability and reliability, and modularizing the scattered parts to achieve rapid installation.

[0024] The first adjustment unit includes a first connector and a second connector. The first connector is used to connect the first connecting seat 1 and the second connecting seat 2, and the second connector is used to connect the second connecting seat 2 and the base 3.
