Description

Technical Field

[0001] This utility model relates to the field of x-ray detection auxiliary technology, specifically to a fixing device for angle adjustment. Background Technology

[0002] X-ray inspection is a non-destructive testing technique that uses X-rays to penetrate objects and create images. It is widely used in fields such as electronics, semiconductors, aerospace, and medicine. The physical basis of X-rays is that they are electromagnetic waves with extremely short wavelengths and high energy. They are penetrating and attenuate differently for materials of different densities. X-ray sources emit X-rays that penetrate the object being tested (such as PCBs and electronic components).

[0003] Existing X-ray inspection-aided fixation devices still have the following problems when in use: most traditional X-ray inspection fixation devices can only achieve horizontal fixation of the circuit board and cannot adjust the angle of the circuit board; some devices with angle adjustment functions have limited adjustment range, which is difficult to meet the diverse angle requirements of complex circuit board inspection. In addition, during the angle adjustment process, there are also problems of unstable fixation and easy shaking of the circuit board, which not only affects the clarity of the inspection image, but also reduces the accuracy and reliability of the inspection. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an angle-adjustable fixing device, which solves the problems mentioned in the background art.

[0006] (ii) Technical solution.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an angle-adjustable fixing device, comprising a bottom mounting mechanism, the bottom mounting mechanism comprising a rectangular frame, a connecting frame fixedly connected between the middle of the inner sidewalls at both ends of the rectangular frame, an assembly hole provided between the center positions of the upper and lower sidewalls of the connecting frame, and a rotation adjustment mechanism rotatably mounted in the assembly hole, an angle adjustment mechanism provided at the top of the rotation adjustment mechanism, the angle adjustment mechanism being configured with a fixing mechanism, the rotation adjustment mechanism comprising a connecting shaft rotatably connected in the assembly hole, a gear fixedly connected at the top of the connecting shaft, two connecting blocks symmetrically fixedly connected at the top of the gear, a rack meshing with the rear end of the gear, the rack being configured with a horizontal drive mechanism, the angle adjustment mechanism comprising a U-shaped seat fixedly connected to the top of the two connecting blocks, the fixing mechanism comprising two mounting seats symmetrically rotatably mounted in the upper part of the U-shaped seat, the two mounting seats being configured with a synchronous drive mechanism.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, by rotating the U-shaped seat 360° and adjusting the angle of its internal fixing mechanism from 0° to 90°, it can provide the circuit board with a full range of diverse inspection angles, allowing X-rays to penetrate the circuit board from different directions, clearly presenting the structure and solder joints of various parts inside the circuit board, effectively reducing blind spots and improving inspection accuracy.

The fixing mechanism 4 includes two mounting seats 42 rotatably installed in a front-to-back symmetrical manner on the upper part of the U-shaped seat 26. The two mounting seats 42 are equipped with a synchronous drive mechanism. The whole device is driven by the 360° rotation of the U-shaped seat 26 and the angle of the fixing mechanism 4 within it (0°-) The 90° tilt adjustment provides a full range of diverse inspection angles for the circuit board, allowing X-rays to penetrate the circuit board from different directions, clearly revealing the structure and solder joints of various parts inside the circuit board, effectively reducing blind spots and improving inspection accuracy.

[0020] A mounting base 14 is fixedly connected to the lower middle part of the outer side wall at both ends of the rectangular frame 11. Two mounting holes are opened symmetrically between the upper and lower side walls of the mounting base 14. The overall fixing device can be fixed and installed by the mounting holes on the two mounting bases 14 and the fixing components to adapt to the X-ray source emission detection equipment. A mating fixing block 43 is fixedly connected to each of the four corners of the lower side wall of the mounting base 42. The mating fixing block 43 has mating holes between the upper and lower side walls. The circuit board to be tested can be placed in the mounting base 42 and fixed by the mating fastening components through the mating holes on the four mating fixing blocks 43.

[0021] The horizontal drive mechanism includes an electric guide rail 21 fixedly connected to the rear of the top of the rectangular frame 11. An electric slider 22 is slidably mounted on the outside of the electric guide rail 21. A rack 23 is fixedly connected to the front end of the electric slider 22. The electric guide rail 21 can drive the electric slider 22 to move, and then drive the gear 24 meshing with it to rotate via the rack 23, thereby realizing the rotation of the U-shaped seat 26.

[0022] A set of shaft holes 27 is provided at each of the two ends of the inner side wall of the U-shaped base 26. There are two shaft holes 27 arranged symmetrically front and back. A balance shaft 41 is rotatably connected in the shaft hole 27. The mounting base 42 on the corresponding side is fixedly connected between the two balance shafts 41 on the front or rear side. The circuit board mounting module is provided with a balance shaft 41, that is, the two ends of its circuit board mounting base 42 are provided with balance shafts 41. It is rotatably mounted in the shaft hole 27 of the U-shaped base 26 and can be driven by a synchronous drive mechanism to rotate smoothly.

[0023] The synchronous drive mechanism includes a drive motor 31 fixedly installed on the lower side of the outer wall of one end of the U-shaped seat 26.

The transmission belt 34 can drive the two mounting seats 42 to rotate synchronously, so as to achieve the tilt adjustment of the inner fixing mechanism 4 from 0° to 90°.

[0024] The working principle of this utility model is as follows: The circuit board to be tested can be placed in the mounting base 42, and the circuit board to be tested is fixed by the mounting fastening components through the mating holes on the surrounding fixing blocks 43. The overall fixing device can be fixed by the mounting holes on the two mounting seats 14 to adapt to the X-ray source emission detection equipment. The X-ray source emits X-rays that penetrate the object under test, i.e., the circuit board. Due to the density difference, the internal structure of the object (such as metal solder joints and defects) absorbs X-rays differently, resulting in different X-ray intensities received by the detector. The detector converts the X-ray intensity into an electrical signal, which is then processed to generate a grayscale image (the higher the density, the brighter the image), thereby displaying the internal structure of the object. Because the whole system can be adjusted by the 360° rotation of the U-shaped base 26 and the tilt of its internal fixing mechanism 4 from 0° to 90°, it can provide the circuit board with a full range of diverse detection angles, allowing X-rays to penetrate the circuit board from different directions, clearly presenting the structure and solder joints of various parts inside the circuit board, effectively reducing the detection blind zone and improving the detection accuracy.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
