Description

Technical Field

[0001] The present application relates to the technical field of infrared refrigeration detectors, and in particular to a dewar bracket tooling. Background Art

[0002] Infrared focal plane detectors have the advantages of high sensitivity, good environmental adaptability, strong anti-interference ability, light weight and low power consumption. They are widely used in aerospace infrared remote sensing, national defense, meteorology, environment, medicine and scientific instruments.

[0003] In the field of monochromatic detection, indium antimonide (InSb) focal plane detectors have obvious advantages in production cost, pixel uniformity, and consistency. InSb infrared focal plane detectors are temperature-sensitive devices, and their performance is directly affected by their operating temperature. For devices in the infrared band, since their performance at room temperature cannot meet application requirements or even cannot work, they often need to be cooled and the operating temperature must be kept stable. Even devices that can work at room temperature often need to stabilize their operating temperature. Therefore, a suitable packaging structure must be used and the operating temperature of the device must be precisely measured and controlled. The most commonly used package for InSb infrared focal plane detectors is the Dewar package, but in the existing medium-measurement Dewar packaging process, the Dewar bottom refrigerator must be removed before patching and bonding, resulting in low production efficiency. To this end, the utility model proposes a Dewar bracket tooling. Utility Model Content

[0009] Optionally, the number of the second fixing members is two;

[0035] There are two second fixing members 2 , which are symmetrically arranged on the left and right sides of the first fixing member 1 and are detachably connected to the first fixing member 1 .

[0036] It should be noted that by providing two second fixing members 2 with completely identical structures, two Dewars can be loaded at the same time, further improving production efficiency.

[0037] A plug rod 22 is fixedly provided on one side of the second fixing member 2 close to the first fixing member 1, and a slot 12 for plugging with the plug rod 22 is correspondingly provided on the first fixing member 1.
