Description

Technical Field

[0001] The present application relates to the field of infrared thermal imagers, and in particular to an infrared thermal imager with a macro lens. Background Art

[0002] An infrared thermal imager is an advanced imaging device that captures and displays infrared radiation emitted from an object's surface as an image of its temperature distribution. The core advantage of an infrared thermal imager lies in its ability to observe in complete darkness or through smoke and other visual obstructions. Macro lenses, on the other hand, are designed to provide highly magnified images, enabling users to observe details of small objects or conduct close-up scientific observations. Combining a macro lens with infrared technology improves the performance of infrared imaging systems for close-range observation and detailed analysis. The demand for infrared thermal imagers equipped with macro lenses is particularly prominent in areas such as scientific research, industrial quality inspection, art authentication, circuit board soldering, precision component inspection, laser fiber inspection, monitoring of e-cigarette heating wires, and chip integration development and testing. In these fields, heat source detection requires not only highly sensitive thermal imagers but also macro lenses capable of clearly capturing subtle structures.

[0003] In existing technologies, infrared thermal imagers capture infrared radiation from the surface of a device to identify hotspots and temperature distribution, helping engineers monitor the soldering process of PCBs, check the thermal management efficiency of electronic equipment, and identify potential failure points. In the early stages of soldering, especially when soldering tiny components like 0201 packages or precision components like QFN and QFP, an infrared thermal imager with a macro lens can accurately detect the temperature distribution of these small components. For soldering larger PCBs or entire panels, infrared thermal imagers can effectively monitor the temperature distribution over large areas, ensuring a uniform and stable soldering process.

[0004] Infrared thermal imaging technology has broad application prospects in the conservation of artworks and cultural relics. It has been applied in a variety of applications, including detecting hollowing in murals, capillary water distribution in caves, and inspecting electrical equipment in museum exhibition halls. Infrared thermal imaging not only rapidly and non-contactly scans and acquires surface temperature information on the object being inspected, but also reveals potential problems such as hollowing, moisture, and cracking through temperature differences, making it crucial for the preventative conservation of artworks and cultural relics. Macro infrared cameras offer even more precise and up-close imaging. They can capture thermal images of small objects or areas, making them particularly useful for applications requiring precise monitoring. For example, when examining temperature changes in small paintings, sculpture details, or minute cracks, macro infrared cameras can detect and analyze temperature distribution at extremely close range, providing precise data support for the restoration and conservation of artworks and cultural relics.

[0005] However, macro lenses and infrared lenses usually exist as independent devices, fixed to the infrared lens via threads or other mechanical connections. When the macro function is not in use, the macro lens needs to be disassembled. In some emergency situations, the opportunity for detection may be missed due to reassembly of the macro lens, resulting in inconvenience and increased economic costs. For example, in scientific research or experiments, it is sometimes necessary to observe and record certain phenomena or effects immediately. If an unexpected situation occurs during an experiment, an infrared thermal imager with macro lens is needed for a detailed inspection immediately. However, the installation of the macro lens becomes an obstacle, and the opportunity to capture critical data may be missed, affecting the research progress or the accuracy of the results. In the event of a power failure or sudden change in ambient temperature and humidity in a museum, the surface temperature of the cultural relics needs to be monitored immediately and in detail. If a macro lens is still required on-site at this time, it may lead to delayed discovery and treatment of damage to the cultural relics, increasing the risk of damage to the cultural relics.

[0006] Therefore, it is necessary to provide an infrared thermal imager with a macro lens that is easy to use and can protect the infrared lens. Utility Model Content

[0040] A flip cover plate, one end of which is rotatably connected to one end of the mounting groove via a rotating shaft;

[0041] a second lens assembly disposed on the flip cover, wherein the second lens assembly and the flip cover are jointly covered in the mounting groove to seal the first lens assembly, and the first lens assembly is aligned with the second lens assembly;

[0042] The second lens assembly includes a second lens component, which is a protective lens or a macro lens. Either the protective lens or the macro lens is detachably connected to the flip cover.

[0043] The infrared thermal imager with a macro lens provided above comprises a flip cover connected to a mounting slot of a housing and disposed within the mounting slot, which rotates via a rotating shaft, and a second lens assembly disposed on the flip cover. This allows for quick lens switching by flipping the cover, eliminating the need for carrying additional tools or equipment, thereby improving ease of use and work efficiency. Furthermore, the second lens assembly and the flip cover are disposed together to cover the mounting slot, protecting the first lens assembly from physical damage and environmental contamination. This allows for quick lens switching in different application scenarios while ensuring reliability and safety.

[0044] The following embodiments of the present application are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0045] according to Figures 1-9 In the embodiment of the present application, an infrared thermal imager 100 with a macro lens 412 is provided. The housing 10 is provided with a mounting slot 111. A first lens assembly 20 is connected to the housing 10 and is located in the mounting slot 111. The first lens assembly 20 includes a mounting base 21 and a first lens piece 22. The mounting base 21 is connected to the mounting slot 111 and has a fixing hole 21a. The first lens piece 22 is located in the fixing hole 21a. A flip cover 30 is provided. One end of the flip cover 30 is rotatably connected to the mounting slot 111 via a rotating shaft. one end of the flip cover 30 so that the flip cover 30 can be flipped through the rotating shaft; the second lens assembly 40 is provided on the flip cover 30, and the second lens assembly 40 and the flip cover 30 are jointly covered in the mounting groove 111 to seal the first lens assembly 20, and the first lens assembly 20 is aligned with the second lens assembly 40; wherein, the second lens assembly 40 includes a second lens component 41, and the second lens component 41 is a protective lens 411 or a macro lens 412, and either the protective lens 411 or the macro lens 412 is detachably connected to the flip cover 30.

[0046] Specifically, the mounting base 21 is secured to the mounting slot 111 of the housing 10 using screws, bolts, or other fixing methods. The mounting base 21 includes a fixing hole 21a that supports the first lens element 22. A flip cover 30 is connected to the mounting slot 111 of the housing 10 via a hinge, allowing for easy flipping of the flip cover 30. The second lens assembly 40 is mounted on the flip cover 30 and moves with it, selectively covering the first lens assembly 20 to protect it or enhance its imaging capabilities. When the second lens assembly 40 is needed, the user hinges the flip cover 30 over the mounting slot 111, aligning the second lens assembly 40 with the first lens assembly 20 and achieving high-magnification imaging. When the second lens assembly 40 is no longer needed and only the first lens assembly 20 is in use, the user hinges the flip cover 30 open, exposing the first lens assembly 20 within the mounting slot 111, ensuring compatibility with all objects capable of heat source detection.

[0047] Furthermore, in an embodiment of the present application, the second lens component 41 is the core part of the second lens assembly 40, and the second lens component 41 directly determines the functional mode of the thermal imager. When the protective lens 411 is selected, its main function is to protect the first lens assembly 20 from physical damage and environmental pollution, thereby extending the service life of the equipment. When the macro lens 412 is selected, the macro lens 412 provides a high-magnification magnification function, allowing users to observe the details of small objects or conduct close scientific observations. By selectively disassembling to select the protective lens 411 or the macro lens 412, the user is allowed to replace the second lens component 41 according to different usage requirements, thereby improving the applicability and flexibility of the equipment.

[0048] In summary, when the thermal imager is not in use, the user selects the protective lens 411 as the second lens assembly 41 and rotates the flip cover 30, connected to the second lens assembly 41 on the flip cover 30, along the hinge, so that the flip cover 30 covers the first lens assembly 20, ensuring the safety of the first lens assembly 20. When the thermal imager is in use, the original protective lens 411 is removed and the macro lens 412 is installed. When the macro function is not required during operation, the flip cover 30 is opened, moving the macro lens 412 away from the first lens assembly 20. To use the macro function again, the flip cover 30 is simply closed, covering the first lens assembly 20. The macro lens 412 is aligned with the first lens assembly 20, thereby achieving high-magnification imaging. This allows the user to quickly switch between the first lens assembly 20 and the second lens assembly 40 according to actual needs without requiring complex operations or specialized tools.

[0049] In a specific embodiment, the protective lens 411 has a protective lens 411 a, which is integrally connected to the second lens component 41 ; the macro lens 412 has a macro lens 412 a, which is detachably mounted on the second lens component 41 .

[0050] Specifically, in the embodiment of the present application, the protective lens 411a can be an ordinary, non-functional lens that can protect the first lens assembly 20 when not in use. The macro lens 412a is a key part of the macro lens 412, providing a high-magnification magnification function, allowing users to observe the details of small objects or conduct close-up scientific observations.

[0051] In a specific embodiment, the flip cover plate 30 has a mounting hole 31, and the second lens assembly 40 also includes a fixing plate 42, which is arranged on the lower bottom surface of the mounting hole 31, and the second lens component 41 is connected to the fixing plate 42; wherein, the hole wall of the mounting hole 31 is provided with a first limit block 311, the side wall of the second lens component 41 is provided with a first limit groove 413, and the end face of the second lens component 41 is provided with a second limit block 414, so that when the second limit block 414 is rotated, the first limit block 311 can extend into the first limit groove 413.

[0052] Specifically, the first limit block 311 is integrally connected to the flip cover 30, and the second limit block 414 is integrally connected to the second lens component 41. The fixing plate 42 is fixed to the mounting hole 31 of the flip cover 30 using screws, bolts, etc., providing support for the second lens component 41. The hole wall of the flip cover 30 is provided with a first limit block 311 that can limit the position. The first limit block 311 can be engaged with the first limit groove 413 of the second lens component 41 to ensure that the second lens component 41 is fixed to the flip cover 30. At the same time, it prevents the second lens component 41 from rotating or moving unnecessarily during use, thereby ensuring the stability of the second lens component 41 and the flip cover 30.

[0053] In a specific embodiment, the first limiting groove 413 includes an extending portion 4131 and a locking portion 4132 connected to the extending portion 4131, the extending portion 4131 is arranged along a vertical direction of the end face of the second lens component 41, and the locking portion 4132 is arranged along a parallel direction of the end face of the second lens component 41; wherein, the locking portion 4132 has a protrusion 4132a, and the first limiting block 311 has a limiting groove 311a, and the protrusion 4132a can extend into the limiting groove 311a.

[0054] Specifically, the first limiting groove 413 is composed of an extending portion 4131 and a locking portion 4132. The extending portion 4131 is arranged perpendicular to the end surface of the second lens component 41, so that when the second lens component 41 is installed, the first limiting block 311 can enter the first limiting groove 413 along the perpendicular direction of the extending portion 4131. The locking portion 4132 is arranged parallel to the end surface of the second lens component 41, so that when the first limiting block 311 enters the extending portion 4131, it can move to the locking portion 4132, thereby locking the position of the second lens component 41. The raised portion 4132a of the locking portion 4132 is a small protrusion on the locking portion 4132, which is used to enhance the locking mechanism. When the first limit block 311 is moved into the locking portion 4132, the limiting groove 311a on the first limit block 311 engages with the raised portion 4132a of the locking portion 4132, thereby providing stability to the first limit block 311 and the first limiting groove 413, preventing the second lens component 41 from accidentally moving or rotating during use.

[0055] Furthermore, when the user aligns the second lens component 41 with the fixed plate 42 and pushes it in, the first limiting block 311 on the flip cover 30 enters the first limiting groove 413 along the extending portion 4131. At the same time, using the strength of the fingers and palm, the user rotates the second limiting block 414 on the second lens component 41 in a translational manner, so that the first limiting groove 413 moves relative to the first limiting block 311, so that the first limiting block 311 reaches the locking portion 4132. The second lens component 41 is gently rotated again so that the protrusion 4132a aligns with and extends into the limiting groove 311a, thereby locking the position of the second lens component 41. When it is necessary to remove or adjust the second lens component 41, the user only needs to rotate the second lens component 41 in the opposite direction to release the protrusion 4132a from the limiting groove 311a, and then lift the second limiting block 414 to remove the second lens component 41 from the fixed plate 42.

[0056] In a specific embodiment, the mounting groove 111 has a first mounting opening 1111 and a second mounting opening 1112 arranged opposite to the first mounting opening 1111, and the flip plate 30 has a first mounting portion 30a and a second mounting portion 30b extending along the extension direction of the flip plate 30, the first mounting portion 30a is arranged on the first mounting opening 1111, the second mounting portion 30b is arranged on the second mounting opening 1112, and the rotating shaft is arranged on the second mounting opening 1112.

[0057] Specifically, the mounting slot 111 has two mounting openings, one on each side of the housing 10, for receiving the two mounting portions of the flip cover 30. The first mounting portion 30a and the second mounting portion 30b of the flip cover 30 extend along the extension direction of the flip cover 30 and are configured to mate with the mounting openings on the housing 10. The second mounting portion 30b is positioned on the second rotation axis, allowing the flip cover 30 to flip over at the second mounting opening 1112 while the second mounting portion 30b flips around the rotation axis.

[0058] Furthermore, the flip cover 30 is installed on the shell 10, the first mounting portion 30a of the flip cover 30 is aligned with the first mounting opening 1111 of the shell 10, and the second mounting portion 30b is arranged on the second mounting opening 1112. When the flip cover 30 needs to be opened or closed, the user only needs to press or slide the first mounting portion 30a to make the flip cover 30 flip along the rotation axis of the second mounting portion 30b.

[0059] In a specific embodiment, the mounting groove 111 further has a third limit block 1113 and a fourth limit block 1114, and the side wall of the flip plate 30 has a second limit groove 30c. The third limit block 1113 and the fourth limit block 1114 are arranged around the rotating shaft so that when the flip plate 30 is closed, the third limit block 1113 is arranged in the second limit groove 30c, and when the flip plate 30 is flipped over, the fourth limit block 1114 is arranged in the second limit groove 30c.

[0060] Specifically, the third and fourth stoppers 1113, 1114 are integrally connected to the housing 10. They provide additional support for the flip cover 30 and restrict its movement at specific locations, ensuring stability when the flip cover 30 is closed or flipped. The second stopper 30c on the sidewall of the flip cover 30 interacts with the third or fourth stopper 1113, 1114. When the flip cover 30 is closed, the second stopper 30c aligns and engages with the third stopper 1113, thereby maintaining a stable closed position and protecting the first lens assembly 20. When the flip cover 30 is flipped, the second stopper 30c aligns and engages with the fourth stopper 1114, maintaining a stable open position.

[0061] In a specific embodiment, the installation slot 111 further has a fifth limiting block 1115 . The fifth limiting block 1115 is disposed on both sides of the first installation opening 1111 , and the fifth limiting block 1115 is an elastic structure.

[0062] Specifically, the fifth stopper 1115 can be a thermoplastic elastomer material with a TPE soft adhesive, which has a certain degree of flexibility and can undergo a certain degree of deformation when the fifth stopper 1115 is subjected to pressure. The fifth stopper 1115 is located on both sides of the first mounting opening 1111. When the flip cover 30 is closed, the first mounting portion 30a of the flip cover 30 is slightly pressed to allow the edge of the flip cover 30 to pass through the fifth stopper 1115. After the flip cover 30 is fully inserted into the mounting groove 111, the fifth stopper 1115 can return to its original position, thereby locking the position of the flip cover 30. When the user aligns the first mounting portion 30a of the flip cover 30 with the first mounting opening 1111 of the housing 10 and pushes it in, the fifth stopper 1115 is subjected to the pressure of the flip cover 30 and undergoes a slight elastic deformation. When the flip cover 30 completely enters the installation slot 111 , the fifth limiting block 1115 returns to its original position, thereby locking the position of the flip cover 30 and ensuring its stability during use.

[0063] In a specific embodiment, the infrared thermal imager further includes a display assembly 50 , which is connected to the housing 10 and is disposed opposite to the first lens assembly 20 .

[0064] Specifically, the display assembly 50 and the first lens assembly 20 are arranged on both sides of the housing 10 relative to each other, so that the user can naturally see the screen when holding the device, while also protecting the screen from direct influence of the heat source.

[0065] In one embodiment, the housing 10 includes a first shell 10a and a second shell 10b, and the first shell 10a and the second shell 10b are connected to enclose a chamber.

[0066] Specifically, in the embodiment of the present application, the housing 10 is a shell with a handle, and the first shell 10a and the second shell 10b are connected by screws, limit blocks, limit grooves or other fixing methods.

[0067] In a specific embodiment, the infrared thermal imager also includes an operating component 60, which is disposed on the shell 10 and electrically connected to the display component 50; wherein the operating component 60 has a first button group 61 and a second button group 62, the first button is disposed on the first shell 10a and is arranged along the extension direction of the display component 50, and the second button group 62 is disposed on the second shell 10b and is arranged away from the first button group 61.

[0068] Specifically, the operating assembly 60 is a button used by the user to operate the infrared thermal imager. The first operating assembly 60 is located on the first housing 10a in the direction extending from the display assembly 50, allowing the user to indicate operations while observing the display assembly 50. The second operating assembly 60 may be a button for controlling the entire infrared thermal imager. The user can control the second operating assembly 60 with their index finger by placing their thumb on the first housing 10a, grasping the handle with their palm, and placing the other four fingers on the second housing 10b.

[0069] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
