Description

Technical Field

[0001] This utility model relates to the field of infrared measurement and calibration equipment, specifically to an infrared camera penetration measurement calibration fixture. Background Technology

[0002] Infrared cameras, with their non-contact penetration measurement advantages, are widely used in high-precision scenarios such as semiconductor chip inspection and industrial non-destructive testing. Their installation stability and positioning accuracy directly determine the reliability of measurement and calibration data. In actual operation, infrared cameras need to be fixed to a measurement calibration mount using a dedicated carrier, and require frequent disassembly and reassembly to adapt to different inspection tasks or for maintenance.

[0003] The existing process for disassembling and assembling infrared cameras and measurement calibration mounts is cumbersome. Most installation structures require multiple tools and have poor locking reliability. Conventional locking structures rely on a single thread for fixation and lack anti-loosening design. Over long-term use or under vibration, bolts may loosen due to self-rotation, leading to camera installation position displacement.

[0004] Therefore, it is necessary to invent an infrared camera penetration measurement calibration mount to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an infrared camera penetration measurement calibration base. Through the inclined fit of the mounting component's snap-fit ​​and locking component, the axial preload of the locking bolt, and the snap-fit ​​design of the locking mechanism's slot and limit ring, the connection between the connector and the mounting base is double-fixed and prevented from loosening. This solves the problems of cumbersome disassembly and assembly, unreliable locking, and easy loosening and displacement of infrared cameras and measurement calibration bases in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an infrared camera penetration measurement calibration base, comprising; The mounting base is fixedly installed on the lower part of the measurement and calibration base. A sliding groove is provided on the upper left side of the mounting base. A connector is fixedly installed on the lower part of the mounting base via a mounting assembly. An infrared camera module is fixedly installed on the lower part of the connector. The mounting assembly includes a positioning plate. Two sets of support columns are fixedly connected to the lower part of the positioning plate. The positioning plate and support columns slide on the inner walls of the mounting base and connector. A support plate is fixedly connected to the lower part of the support columns. A snap-fit ​​component is slidably connected to the outer side of the support columns. A locking bolt is threadedly connected to the inner wall of the support plate via a nut. The locking bolt abuts against the lower part of the snap-fit ​​component. A locking member is fixedly connected to the lower left side of the connector. The snap-fit ​​component fits against the lower surface of the locking member. A plug-in part is rotatably connected to the lower right side of the mounting base. The right side of the connector is plugged into the inner wall of the plug-in part. A locking mechanism is provided between the locking bolt and the support plate.

[0007] Preferably, the locking mechanism includes a limiting ring, which is fixedly connected to the lower part of the support plate. Multiple sets of snap-fit ​​parts are fixedly connected around the upper part of the rotating part of the locking bolt. The snap-fit ​​parts have a slot near the thread of the locking bolt, and the slot engages with the outside of the limiting ring.

[0008] Preferably, the left side of the plug portion is hollow.

[0009] Preferably, the nut is fixedly connected to the upper inner wall of the support plate.

[0010] Preferably, the connector has two sets of through slots on its left side, and the width of the through slots is greater than the diameter of the support column.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention achieves dual fixation of the connector and mounting base by using the inclined fit of the snap-fit ​​and locking parts of the mounting component, combined with the axial preload of the locking bolt. The locking mechanism's slot and limit ring prevent the locking bolt from loosening, maintaining the stability of the infrared camera module's installation position even in vibration environments and avoiding a decrease in calibration accuracy due to loosening. No tools are required; locking and unlocking of the connector and mounting base can be completed simply by rotating the locking bolt. With the auxiliary positioning of the plug-in part, the assembly and disassembly process is quick and easy. Attached Figure Description

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] This utility model provides, for example Figure 1 - Figure 3 An infrared camera penetration measurement calibration fixture is shown, including a mounting base 1; Mounting base 1 is fixedly installed at the lower part of the measurement calibration base, serving as the basic carrier of the overall installation structure and providing stable support for all components. A sliding groove 5 is provided on the upper left side of mounting base 1 to provide movement space and adapt to calibration needs at different positions. A connector 3 is fixedly installed at the lower part of mounting base 1 via mounting component 2, achieving a stable connection between mounting base 1 and connector 3 and ensuring installation accuracy. An infrared camera module 4 is fixedly installed at the lower part of connector 3, receiving infrared radiation signals after penetrating the semiconductor chip packaging layer and converting them into recognizable images or electrical signals to provide calibration and measurement data. The original data supports the accurate capture of the infrared characteristics of the calibration target. Mounting component 2 includes a positioning plate 21, which serves as a positioning guide and ensures the verticality of the support columns 22. Two sets of support columns 22 are fixedly connected to the lower part of the positioning plate 21, connecting the positioning plate 21 and the support plate 23 to form the support frame of mounting component 2. When the connector 3 needs to be disassembled, the support columns 22 need to be moved. The positioning plate 21 and support columns 22 slide on the inner walls of the mounting base 1 and the connector 3, achieving a sliding fit between mounting component 2 and the mounting base 1 and connector 3, facilitating position adjustment. The lower part of the support column 22... A support plate 23 is fixedly connected, providing an installation platform for the locking bolts 25 and the snap-fit ​​parts 24, enhancing structural stability. The snap-fit ​​parts 24 are slidably connected to the outer side of the support column 22, and through cooperation with the snap-fit ​​parts 26, the connecting parts 3 are locked in place. The inner wall of the support plate 23 is threadedly connected to the locking bolts 25 via nuts 6. Rotation adjustment allows the snap-fit ​​parts 24 to rise and fall, thereby controlling locking and unlocking. Nuts 6 are fixedly connected to the inner wall of the support plate 23, and the locking bolts 25 abut against the lower part of the snap-fit ​​parts 24, providing upward support and ensuring the snap-fit ​​effect. A snap-fit ​​component 26 is fixedly connected to the lower left side of component 3, which cooperates with the snap-fit ​​component 24 to form a snap-fit ​​structure, enhancing the connection stability between component 3 and mounting base 1. The snap-fit ​​component 24 fits against the lower surface of the snap-fit ​​component 26. A plug-in portion 27 is rotatably connected to the lower right side of mounting base 1, providing positioning support for the right side of component 3, ensuring the coaxiality of component 3 after installation, and facilitating installation. The right side of component 3 is inserted into the inner wall of plug-in portion 27. A locking mechanism 28 is provided between the locking bolt 25 and the support plate 23 to prevent the locking bolt 25 from rotating accidentally and to ensure the stability of the locked state.

[0017] like Figure 3 - Figure 5As shown, the locking mechanism 28 includes a limiting ring 281, which is fixedly connected to the lower part of the support plate 23. Multiple sets of locking parts 282 are fixedly connected around the upper part of the rotating portion of the locking bolt 25. These locking parts cooperate with the limiting ring 281 to restrict the rotation of the locking bolt 25. The locking parts 282 have a slot 283 near the thread of the locking bolt 25, which precisely engages with the limiting ring 281. The slot 283 engages with the outer side of the limiting ring 281, preventing the locking bolt 25 from loosening through mechanical engagement. The left side of the insertion part 27 is hollow. The nut 6 is fixedly connected to the upper inner wall of the support plate 23. Two sets of through slots are provided on the left side of the connector 3 to provide a margin of movement for the support column 22, facilitating installation and adjustment. The width of the through slots in the connector 3 is greater than the diameter of the support column 22 to avoid interference between the support column 22 and the inner wall of the through slots, ensuring adjustment flexibility.

[0018] The working principle of this utility model is as follows: First, fix the mounting base 1 on the lower part of the measurement and calibration base as the overall installation reference. Align the right side of the connector 3 with the insertion part 27 of the mounting base 1 and insert it. Through the positioning support of the insertion part 27, rotate the insertion part 27 and adjust the connector 3 so that it fits against the outside of the mounting base 1. At this time, the positioning plate 21 and the support column 22 of the mounting component 2 slide into the inner wall of the connector 3 respectively.

[0019] Rotate the locking bolt 25, which moves upward through its threaded engagement with the nut 6, pushing the snap-fit ​​24 to slide upward along the support column 22. The snap-fit ​​24 and the snap-fit ​​26 gradually come into contact and tighten, forming a lateral locking force. At the same time, the snap-fit ​​part 282 of the locking bolt 25 rotates with the bolt, causing the snap-fit ​​groove 283 to engage with the outside of the limit ring 281. The locking mechanism 28 restricts the circumferential rotation of the locking bolt 25, preventing loosening under vibration and ensuring the stable installation position of the infrared camera module 4.

[0020] Rotate the locking bolt 25 in the opposite direction to move it downward and disengage it from the support of the snap-fit ​​part 24. Under the action of gravity, the snap-fit ​​part 24 slides down along the support column 22 and separates from the snap-fit ​​part 26. At the same time, the slot 283 of the snap-fit ​​part 282 disengages from the limiting ring 281, releasing the circumferential restriction on the locking bolt 25. At this time, the connector 3 can be pulled out from the insertion part 27, and the infrared camera module 4 can be disassembled together to complete the maintenance or replacement.

[0021] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
