[0049] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0050] Example 1

[0051] like Figure 1-5 As shown in Figure 7, this embodiment provides a multifunctional infrared imaging device detection device, which includes:

[0052] The base 1 has an internal mounting space and a platform 103. In this embodiment, as shown... Figure 3 As shown, the base 1 is a frame structure built from aluminum profiles 101 and sheet metal parts 102, which serves as the installation base for other structures.

[0053] Rotary drive assembly 2 is connected to platform 103 of base 1; in this embodiment, as... Figure 4As shown, the rotary drive assembly 2 includes: a rotary drive motor 21 connected to the platform 103 of the base 1; a turntable 22 connected to the rotational power output end of the rotary drive motor 21, and having a plurality of clamp mounting positions 221 evenly spaced along the circumference (e.g., 5 clamp mounting positions 221). In this embodiment, the clamp mounting positions 221 can be hole structures or groove structures, etc.; a plurality of positioning posts 23 vertically connected to the upper surface of the turntable 22; a slip ring 24 used to realize power and signal transmission between the rotary clamp assembly and the fixed-side power supply and host computer; and a cover plate 25 covering the slip ring 24 to prevent foreign objects from contacting the slip ring 24 and dust from entering the slip ring 24, thus avoiding affecting the normal operation of the slip ring 24. In addition, to prevent the cover plate 25 from moving, the cover plate 25 also has through holes that can cooperate with the positioning posts 23. After the positioning posts 23 pass through the through holes, the cover plate 25 can be positioned.

[0054] Several clamping assemblies 3 are connected to the rotary drive assembly 2, and each clamping assembly 3 is used to clamp and fix an infrared imaging device. All clamping assemblies 3 and the infrared imaging device clamped by the clamping assemblies 3 rotate synchronously under the drive of the rotary drive assembly 2.

[0055] Several blackbody components 4 are mounted on the platform 103, and as follows: Figure 6 As shown, each blackbody component 4 includes: a blackbody 41; a blackbody motion module connected to the blackbody 41, used to drive the blackbody 41 to move, so as to adjust the relative positional relationship between the blackbody component 4 and the infrared imaging device held by the clamping component 3. Meanwhile, in this embodiment, at least two blackbody 41 have different temperatures.

[0056] The motion control component 6 (e.g., a PLC controller) is connected to the rotary drive component 2 and / or the blackbody motion module respectively, and is used to control the rotary drive component 2 and / or the blackbody motion module to move according to a predetermined program, so that the same infrared imaging device held by the clamping component 3 can sequentially acquire images of at least two blackbodies 41.

[0057] And, a host computer 5, which is set in the internal installation space of the base 1, is used to perform calculations based on the blackbody image to obtain calculation results, wherein the calculation results include NETD test results and / or non-uniformity correction results.

[0058] Specifically, a clamp assembly 3 is installed on each clamp mounting position 221 of the rotary drive assembly 2, and as shown in the figure... Figure 5 As shown, each fixture assembly 3 includes:

[0059] A fixture mounting cabinet is installed on a fixture mounting position 221, and the fixture mounting cabinet includes a cabinet body 31 with an internal mounting space, a cabinet upper panel 32 detachably connected to the cabinet body 31, and a latch 33 connecting the cabinet body 31 and the cabinet upper panel 32. The cabinet upper panel 32 is parallel to the horizontal plane.

[0060] The fixture control module 34 (such as an industrial computer) is installed inside the cabinet 31 of the fixture mounting cabinet. For example, in this embodiment, the upper panel 32 of the cabinet can be removed first, and then the fixture control module 34 can be installed inside the cabinet 31. The internal installation space of the cabinet 31 can be closed by the upper panel 32 of the cabinet, and the cabinet 31 and the upper panel 32 of the cabinet can be locked by the latch 33. This can enclose the fixture control module 34 inside the cabinet 31 to prevent dust, water, foreign objects and other objects from entering the cabinet 31 and affecting the normal operation of the fixture control module 34.

[0061] The clamp mounting plate 35 is detachably connected to the upper panel 32 of the cabinet. For example, in this embodiment, the clamp mounting plate 35 can be quickly disassembled and assembled by the quick-release female seat 37 installed on the upper panel 32 of the cabinet and the quick-release male seat at the bottom of the clamp mounting plate 35. The clamp mounting plate 35 is symmetrically provided with a first handle 351 and a second handle 352, which are convenient for operators to pick up and put down, so as to quickly connect and install it on the upper panel 32 of the cabinet. When it is necessary to disassemble the mounting plate 35 and other structures on it, it can be achieved by separating the quick-release male seat and the quick-release female seat 37.

[0062] The positioning fixture 36 is mounted on the clamp mounting plate 35 via positioning pins or other structures, and is used to support the infrared imaging equipment.

[0063] A clamp 39 is mounted on the clamp mounting plate 35 and electrically connected to the clamp control module 34. The clamp control module 34 controls the opening and closing of the clamp 39 to clamp and fix the infrared imaging device placed on the positioning fixture 36, preventing the infrared imaging device from moving during rotation and detection. In this embodiment, the clamp 39 includes a first clamp unit 391 and a second clamp unit 392 respectively disposed on one side of the positioning fixture 36. Furthermore, the clamp control module 34 can control the operation of a motor, cylinder, or other driving device to drive the first clamp unit 391 and the second clamp unit 392 to move relative to each other, thereby clamping and fixing the infrared imaging device.

[0064] The interface module 30 is connected to the fixture control module 34 and the external control module (such as an external power supply, host computer, etc.) respectively to realize the transmission of signals (such as power supply signals and other action execution signals) between the fixture control module 34 and the external control module.

[0065] Furthermore, such as Figure 6 As shown, the blackbody motion module includes:

[0066] Linear module 46, which is mounted on the platform 103;

[0067] The lifting module 47 is connected to the linear module 46 and the blackbody 41 respectively;

[0068] Therefore, the lifting module 47 and the black body 41 can be driven to move linearly in the XY plane parallel to the horizontal plane by the linear module 46, and the black body 41 can be driven to move linearly in the height direction by the lifting module 47. Furthermore, the linear module 46 can be composed of modules such as guide rails, motors, lead screws, and drag chains, which are existing technologies. The lifting module 47 includes a scissor-type lifting platform, which includes hydraulic cylinders, scissor frames, and other structures. Its structural configuration is also existing technology and will not be described in detail here.

[0069] Furthermore, such as Figure 8 As shown, the working process of the infrared imaging equipment detection device in this embodiment is illustrated by setting five clamp components 3 (1#-5#) and four blackbody components 4 (1#-4#), with the blackbody 41 of the four blackbody components 4 (1#-4#) having temperatures of 20℃, 25℃, 30℃, and 60℃ respectively:

[0070] The clamp control module 34 of clamp assembly 3 controls the movement of its clamp 39 to clamp and fix an infrared imaging device.

[0071] The motion control component 6 controls the rotation drive motor 21 of the rotation drive component 2 to drive the #1 clamp component 3 and the clamped infrared imaging device to rotate to a predetermined position, so that the positions of the infrared imaging device and the #1 blackbody component 4 are roughly corresponding.

[0072] The motion control component 6 controls the blackbody motion module of the #1 blackbody component 4 to drive the blackbody 41 of the #1 blackbody component 4 to move horizontally and / or vertically, so that the blackbody 41 is completely within the imaging field of view of the infrared imaging device.

[0073] The infrared imaging device acquires an image of the blackbody 41 of the #1 blackbody component 4 and sends the blackbody image to the host computer 5. The host computer 5 performs calculations based on the blackbody image to obtain the calculation results, such as the NETD test results of the infrared imaging device when the blackbody temperature is 20℃.

[0074] The motion control component 6 controls the rotary drive motor 21 of the rotary drive component 2 to rotate counterclockwise, driving the infrared imaging device to rotate to the position of the blackbody 41 of the blackbody component 4, obtaining an image of the blackbody 41 of the blackbody component 4. The host computer 5 obtains the calculation results through the blackbody image of the blackbody component 4, such as the NETD test result of the infrared imaging device when the blackbody temperature is 25℃. At the same time, the clamp control module 34 of the clamp component 3 controls the clamp 39 to move to clamp and fix another infrared imaging device, so as to complete the product loading at the clamp component 3.

[0075] By repeating the loading and rotation process of the fixture assembly 3, the testing of 5 infrared imaging devices can be completed in a predetermined order.

[0076] Therefore, the detection device in this embodiment has a reasonable structural design, strong practicality and high versatility. It can quickly clamp infrared imaging devices through the clamping assembly 3, and drive several infrared imaging devices sequentially to obtain images of different black bodies by using the rotation drive assembly 2. This can automatically complete different test items such as NETD test results and non-uniformity correction, thereby greatly saving test time and improving detection efficiency. It is especially suitable for the mass production of infrared imaging products.

[0077] Example 2:

[0078] The only difference between this embodiment and Embodiment 1 is that, Figure 6 As shown, each blackbody component 4 also includes:

[0079] The limiting block 42 is disposed on the bottom periphery of the blackbody 41 and moves synchronously with the blackbody 41. It is used to limit the installation position of the blackbody 41 in the circumference to prevent it from undergoing large positional changes, thereby affecting the infrared imaging device from acquiring a complete blackbody image.

[0080] The distance detection module 43 is connected to the blackbody 41 and is used to acquire distance information between the blackbody 41 and the infrared imaging device, and feed it back to the motion control component 6. The motion control component 6 controls the movement of the blackbody motion module according to the distance information, for example, controls the movement of the linear module 46, thereby adjusting the position of the blackbody 41. In this embodiment, the distance detection module 43 includes a structure based on photoelectric sensing signal conversion to acquire distance information, such as a photoelectric switch.

[0081] Example 3:

[0082] The only difference between this embodiment and embodiment 1 or 2 is that, Figure 1-3 As shown in Figure 7, the detection device of the multifunctional infrared imaging equipment further includes:

[0083] The cover 16 has an internal accommodating space and is mounted on the platform 103, such that all clamping assemblies 3, all blackbody assemblies 4, and all clamped infrared imaging devices are located within the internal accommodating space of the cover 16. In this embodiment, the cover 16 can also be made of sheet metal or other materials. The motion control component 6 is mounted on the cover 16 and includes: a motion control switch 61 for controlling the start and stop of the rotation drive assembly 2 and / or the blackbody motion module; and a motion control component display 62 for human-computer interaction and data display.

[0084] The host computer peripherals are all installed on the cover 16 and are electrically connected to the host computer 5 for user interaction with the host computer 5. In this embodiment, the host computer peripherals include one or more of the following: keyboard 12, host computer start switch 11, host computer display 10, etc.

[0085] The prompting module 7 is installed on the cover 16 and is used to generate prompting signals, such as generating an audible and visual alarm signal when the equipment is malfunctioning. In this embodiment, the prompting module 7 includes a tri-color light, etc.

[0086] Safety light curtain 8, which is installed on the cover 16, is used to generate an equipment shutdown signal when an external target (such as a human hand) approaches the equipment, so as to avoid production accidents;

[0087] A cooling fan 9 is mounted on the cover 16 and is used to dissipate heat from the interior space of the cover 16.

[0088] An emergency control module, which is installed on the housing 16, includes a start switch 17 for emergency activation of the multi-functional infrared imaging equipment detection device to start its operation, or an emergency stop switch 18 for emergency shutdown of the multi-functional infrared imaging equipment detection device.

[0089] A door panel 13 is installed on the enclosure 16. Opening the door panel 13 allows the interior of the enclosure 16 to communicate with the external environment, enabling personnel to operate the equipment inside the enclosure 16. Alternatively, closing the door panel 13 isolates the interior of the enclosure 16 from the external environment. In this embodiment, the door panel 13 can be a sliding door structure.

[0090] The base cooling fan 14 is installed on the base 1 and is used to dissipate heat from the internal space of the base 1 to ensure the normal operation of the internal host computer 5 and other equipment.

[0091] And a base support assembly 15, which is disposed at the bottom of the base 1 for supporting the base 1 and its upper structure.

[0092] In summary, the detection device of this invention has a high degree of automation. It can quickly clamp infrared imaging devices through a clamping assembly, and drive several infrared imaging devices sequentially to obtain images of different black bodies by using a rotary drive assembly. The upper computer automatically completes the calculation, thereby automatically completing different test items such as NETD test results and non-uniformity correction, which greatly saves test time and improves detection efficiency.

[0093] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
