Description

Technical Field

[0001] This invention relates to the field of infrared mechanism interface technology, and specifically to a universal infrared mechanism interface device. Background Technology

[0002] An infrared thermal imager consists of an infrared sensor and an infrared lens, which require an adapter to connect them. Because the technical specifications of each thermal imager differ, the distance from the focal point of the optical design to the lens mounting surface (also known as the back distance) varies, as do the distances from the focal plane of different detector types to the mounting surface. Therefore, each time the sensor and lens are assembled, the interface device connecting them needs to be redesigned. Since there are many types of infrared lenses and infrared sensors, and no unified standard exists among manufacturers, many different interface devices are needed to meet various requirements. Factors to consider when designing an interface device include: mounting method, back distance, sensor mounting method, coaxial mounting of the sensor and lens, focal plane alignment between the sensor and lens, and processing time.

[0003] The existing technology has the following problems:

[0004] In the current technology, each type of complete machine needs to be equipped with a custom interface, which is very inconvenient, especially in the experimental and debugging stages, and will cause a lot of waste in terms of time, manpower and processing costs.

[0036] In this embodiment, the fixed platform can be fitted with four screws in the four corner mounting threaded holes 2, and the height of the screws can be adjusted to make the fixed platform and the ground form an angle, so as to achieve the effect of imaging from an upward or downward perspective, in order to find a better observation angle.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the adjustable lens holder includes an adjustable base, an adjustable arc frame, and a fixing component.

[0040] Example 3

[0041] like Figure 1-6As shown, based on Embodiments 1 and 2, the present invention provides a technical solution: Preferably, the three-direction adjustable mechanism fixing base includes a Y-axis adjustment mechanism and a Z-axis adjustment mechanism. The Y-axis adjustment mechanism is installed above the fixed platform, and the Z-axis adjustment mechanism is installed above the Y-axis adjustment mechanism. The Y-axis adjustment mechanism includes a fixing base 14, which is placed above the fixed plate 1. A first support frame 16 is hinged to the top of the fixing base 14. A connecting shaft 17 is fixedly installed on the outer wall of the first support frame 16. A second support frame 18 is rotatably connected to the outer wall of the first support frame 16 via the connecting shaft 17. A support platform 19 is hinged to the top of the second support frame 18. A bearing 20 is fixedly installed on the top of the fixing base 14. A threaded rod 21 is fixedly installed on the inner wall of the bearing 20. A threaded sleeve 22 is threadedly connected to the outer wall of the threaded rod 21. One end of the threaded rod 21 is fixedly installed with... The rotating handle 23 and the fixed base 14 have symmetrical long slots 15 around their periphery. The outer wall of the threaded sleeve 22 is rotatably connected to the end of the second support frame 18 away from the support platform 19. The bottom of the support platform 19 is fixedly installed with a limiting frame 25. The inner wall of the limiting frame 25 is slidably connected with a sliding block 24. The outer wall of the sliding block 24 is rotatably connected to the end of the first support frame 16 away from the fixed base 14. The Z-axis adjustment mechanism includes a connecting platform 26, which is fixedly installed above the support platform 19. The inside of the connecting platform 26 is rotatably connected with an adjusting screw 27. The outer wall of the adjusting screw 27 is threadedly connected with a screw slide 28. The top of the screw slide 28 is fixedly installed with a core fixing seat 30. The inside of the core fixing seat 30 has a fixing threaded hole 31. The inner wall of the connecting platform 26 is fixedly installed with a guide rod 29. The outer wall of the guide rod 29 is slidably connected to the inner wall of the screw slide 28.

[0042] In this embodiment, the Y-axis adjustment mechanism allows the user to easily adjust the Y-axis position of the movement, thereby facilitating the user to achieve coaxiality between the movement center and the lens center. The sliding block 24, in conjunction with the limiting frame 25, can limit the support platform 19, ensuring that the support platform 19 and the fixed base 14 remain horizontal, thus increasing the stability of the support platform 19. The Z-axis adjustment mechanism allows the user to easily adjust the Z-axis position of the movement, thereby facilitating the user to achieve coaxiality between the movement center and the lens center.

[0043] The working principle of this universal infrared core interface device will be explained in detail below.

[0044] like Figure 1-6As shown, the mounting bolts 7 are inserted into the mounting threaded holes 2 at different positions, and the opening and closing of the arc-shaped support frame 6 is controlled by the upper limit slide rod 13 and the lower limit slide rod 8. The opening and closing of the arc-shaped support frame 6 and the arc-shaped connecting ring 11 are controlled by the longitudinal adjusting bolt 10, which can adjust the size of the inner ring of the adjustable arc frame. Finally, by rotating and twisting the first fixing bolt 9 and the second fixing bolt 12, the ends of the first fixing bolt 9 and the second fixing bolt 12 with plastic sleeves are made to fit against the surface of the lens. The lens is clamped and fixed by the squeezing force and torque. The movement is installed on the movement fixing seat 30 by the fastening screw and the fixing threaded hole 31. The mounting threaded hole 2 of the fixing platform is used to adjust the distance from the movement to the focal plane of the lens by the long slot 15. After the adjustment is appropriate, it can be fixed by screwing in the fastening screw. When it is necessary to adjust the Y-axis, the threaded rod 21 is rotated by rotating the rotating handle 23. This causes the threaded sleeve 22 to slide, and the first support frame 16 to rotate between the connecting shaft 17 and the second support frame 18. The support platform 19 is limited by the sliding block 24 and the limiting frame 25, and the support platform 19 is raised horizontally, thereby changing the height of the Y-axis. By rotating the adjusting screw 27, the screw slide 28 is made to slide, thereby changing the position of the movement fixing seat 30 on the Z-axis. The guide rod 29 can limit the movement of the movement fixing seat 30. The fixing platform can be fixed by adding four screws to the four corner mounting threaded holes 2 and adjusting the height of the screws at the four corners to make the fixing platform and the ground form different angles, so as to achieve the effect of imaging from above or below, so as to find a better observation angle. Furthermore, by installing the fixing bracket base 3 and the fixing seat base 14 on the mounting threaded holes 2 in different positions, the distance between the lens and the movement can be adjusted, which is convenient for users to conduct experiments.

[0045] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
