The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] Please see Figures 1 to 9This utility model provides a laser ranging-based device for detecting the distance between cold plate bosses and circuit board components, including a horizontal seat 1, a vertical seat 2, and a base 3. The horizontal seat 1 has a horizontal groove 4, in which a horizontal slider 5 is slidably disposed. A high-precision laser sensor 6 is disposed on the horizontal slider 5, and the high-precision laser sensor 6 is connected to a zeroing button 7. The vertical seat 2 has a vertical groove 8, in which a vertical slider 9 is slidably disposed. The vertical slider 9 is driven by a height adjustment component. A rotating seat 10 is disposed on the vertical slider 9, and a rotating block 11 is rotatably disposed on the rotating seat 10. The rotating block 11 is driven by an angle adjustment component. A circuit board fixing assembly is disposed on the base 3. The horizontal seat 1 is fixedly connected to the rotating block 11 and is located on the rotating block 11. The vertical seat 2 is fixedly connected to the base 3 and is located on the base 3.

[0024] In this embodiment, the non-contact, automated detection of the distance between cold plate bosses and board components is achieved through components such as the horizontal seat 1, the vertical seat 2, the high-precision laser sensor 6, and the zeroing button 7. This innovative design significantly improves measurement efficiency, with a single measurement time of less than 1 second, meeting the needs of mass production. At the same time, the application of the high-precision laser sensor 6 (resolution up to ±0.01mm) greatly improves measurement accuracy, far exceeding the level of manual measurement. In addition, the device dynamically adapts to different board and boss layouts through its precise three-dimensional spatial positioning capability, enhancing the flexibility and versatility of use, and effectively solving the problems of low efficiency, poor accuracy, and weak adaptability of traditional measurement methods.

[0025] Furthermore, the height adjustment component is a height adjustment screw 12, the longitudinal slider 9 has a threaded groove 13, the height adjustment screw 12 is rotatably connected to the longitudinal seat 2 through a bearing and is located in the longitudinal groove 8, and the height adjustment screw 12 is also threadedly connected to the longitudinal slider 9 and is located in the threaded groove 13.

[0026] In this embodiment, the precise lifting and lowering of the longitudinal slider 9 is achieved through a threaded connection.

[0027] Furthermore, the angle adjusting component includes a worm gear 14, a worm 15, and a mounting box 16. The worm gear 14 is disposed at the rotating end of the rotating block 11, and the worm 15 is rotatably disposed in the mounting box 16. The mounting box 16 is fixedly connected to the rotating seat 10 and is located on the rotating seat 10, and the worm 15 meshes with the worm gear 14.

[0028] In this embodiment, the precise angle adjustment and self-locking of the rotating block 11 are achieved through the meshing transmission of the worm gear 14 and the worm 15.

[0029] Furthermore, the board fixing assembly includes two board fixing seats 17 and a bidirectional screw 18. Each board fixing seat 17 is provided with a threaded sleeve 19 below it. The base 3 has an adjustment groove 20. The two board fixing seats 17 are slidably connected to the base 3 and are symmetrically arranged on the base 3. The threaded sleeves 19 extend into the adjustment groove 20. The bidirectional screw 18 is rotatably connected to the base 3 through bearings and is located in the adjustment groove 20. It is also threaded into the two threaded sleeves 19.

[0030] In this embodiment, the two symmetrically arranged board fixing seats 17 are driven by the bidirectional screw 18 to move towards or away from each other, thereby achieving rapid and stable fixing of boards of different sizes.

[0031] Furthermore, each of the card fixing bases 17 is provided with a limiting block 21 at both ends, the base 3 is also provided with two limiting grooves 22, and the adjustment groove 20 is located between the two limiting grooves 22, and the two limiting blocks 21 extend into the corresponding limiting grooves 22 respectively.

[0032] In this embodiment, the cooperation between the limiting block 21 and the limiting groove 22 provides precise guidance and restriction for the sliding of the plate fixing seat 17 on the base 3.

[0033] In this invention, the circuit board to be tested is securely fixed to the base 3 by the circuit board fixing assembly. The distance between the two fixing seats is adjusted by rotating the bidirectional screw 18 to adapt to the size of the circuit board. Then, the height of the longitudinal slider 9 is adjusted by the height adjusting screw 12 so that the high-precision laser sensor 6 on the rotating seat 10 reaches a suitable measurement height. Next, the sensor angle is finely adjusted by the angle adjusting component to ensure that the laser beam is vertically aligned with the target being tested. During measurement, the laser point of the sensor is first aligned with the plane of the screw hole near the device being tested and the zeroing button 7 is pressed for calibration. Then, the circuit board is moved so that the laser point is aligned with the center of the device and the drop value is recorded. Finally, the operation is repeated with the center of the boss and the plane of the screw hole nearby. By comparing the two drop values, the distance between the cold plate boss and the circuit board device is accurately obtained. The whole process realizes non-contact, automated, high-precision and rapid detection.
