Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0032] In one embodiment of this utility model, such as Figures 1-5 As shown, a nano-lifting platform adjustment mechanism is provided, including a drive mechanism 1, a lifting mechanism 2, and an adjustment and limiting mechanism 3. The lifting mechanism 2 is connected to both the drive mechanism 1 and the adjustment and limiting mechanism 3. The adjustment and limiting mechanism 3 is fixed to the lifting mechanism 2. The drive mechanism 1 provides lifting power to the lifting mechanism 2, and the lifting mechanism 2 drives the adjustment and limiting mechanism 3 to lift synchronously. The adjustment and limiting mechanism 3 is used to clamp and limit the PCB board.

[0033] The drive mechanism 1 includes a motor plate 11, a motor base 12, a drive motor 13, a screw 14, a nut 15, and a connecting plate 16. The motor plate 11 is bolted to the bottom of the motor base 12, providing stable support. The drive motor 13 is a high-precision servo motor, bolted to the top of the motor base 12. Its output shaft is fixedly connected to one end of the screw 14 via a coupling, enabling high-precision rotation of the screw 14. The nut 15 is threadedly connected to the screw 14, forming a helical transmission pair. One side of the connecting plate 16 is bolted to the nut 15, and the other side is fixedly connected to the lifting mechanism 2. When the drive motor 13 operates, it drives the screw 14 to rotate, causing the nut 15 to move axially on the screw 14, which in turn drives the lifting mechanism 2 to move up and down via the connecting plate 16.

[0034] The lifting mechanism 2 includes a lifting frame 21, a lifting sleeve 22, and a lifting locking bolt 23. The lifting frame 21 is made of aluminum alloy, which is lightweight and high-strength. One side of it is fixedly connected to the connecting plate 16 by bolts. The lifting sleeve 22 is movably inserted into the guide hole opened on the lifting frame 21 and can slide up and down along the guide hole. The lifting locking bolt 23 is an internal hex bolt, which is threadedly connected to the corresponding threaded holes on the lifting sleeve 22 and the lifting frame 21. When it is necessary to adjust the position of the lifting sleeve 22 or the limit mechanism 3, the lifting locking bolt 23 is loosened. After the lifting sleeve 22 moves to the appropriate position, the lifting locking bolt 23 is tightened to fix it.

[0035] Three lifting sleeves 22 and three lifting locking bolts 23 are provided. The three lifting sleeves 22 are arranged in parallel and spaced apart, with equal spacing between adjacent lifting sleeves 22 to ensure stability during the lifting process. Multiple lifting limit plates 24, made of stainless steel, are also fixedly connected to the side of the lifting frame 21 to limit the movement of the PCB board. Furthermore, the side of the lifting frame 21 is engraved with scale lines 211, located on one side of the lifting sleeves 22, allowing operators to visually observe the adjustable height of the lifting sleeves 22.

[0036] The adjusting limit mechanism 3 includes an adjusting limit base plate 31, an adjusting limit sleeve 32, an adjusting locking bolt 33, and an adjusting limit bolt 34. The adjusting limit base plate 31 is made of steel plate and is fixedly connected to the top of the lifting sleeve 22 by bolts. The adjusting limit sleeve 32 is made of wear-resistant alloy and is movably inserted through the adjusting limit base plate 31, allowing it to slide horizontally along the adjusting limit base plate 31. The adjusting locking bolt 33 is a wing bolt, which is easy to operate manually. It is sequentially inserted through the adjusting limit sleeve 32 and the adjusting limit base plate 31. Once the position of the adjusting limit sleeve 32 is determined, tightening the adjusting locking bolt 33 will fix it on the adjusting limit base plate 31. The adjusting limit bolt 34 is threadedly connected to one end of the adjusting limit base plate 31 and is used to limit the adjustment limit base plate 31.

[0037] Two adjusting limit sleeves 32, two adjusting locking bolts 33, and two adjusting limit bolts 34 are provided. The two adjusting limit sleeves 32 are spaced apart to form a clamping gap for holding the PCB board. By moving the positions of the two adjusting limit sleeves 32 within the elongated holes, the size of the clamping gap can be flexibly adjusted to accommodate PCB boards of different widths.

[0038] There are three adjustment limit mechanisms 3. The three adjustment limit mechanisms 3 are evenly fixedly connected to the top of the three lifting sleeves 22. The distance between two adjacent adjustment limit mechanisms 3 is equal, and the three adjustment limit mechanisms 3 are parallel to each other and spaced apart, forming a stable three-point clamping structure to ensure that the PCB board will not shake or shift during the testing process.

[0039] Work process:

[0040] Clamping size adjustment: According to the size of the PCB board to be tested, loosen the adjusting locking bolt 33 in the adjusting limit mechanism 3, move the two adjusting limit sleeves 32 to make the clamping gap between them match the width of the PCB board. After the adjustment is completed, tighten the adjusting locking bolt 33 to fix the adjusting limit sleeve 32.

[0041] Height adjustment: Start the drive motor 13 in the drive mechanism 1. The drive motor 13 drives the screw 14 to rotate, which drives the lifting frame 21 to move up and down through the nut 15 and the connecting plate 16, thereby realizing the height adjustment of the limit mechanism 3 until the PCB board reaches the optimal detection height of the detection equipment.

[0042] PCB board inspection: The PCB board is placed in the clamping gap of the three adjusting limit mechanisms 3. The PCB board is stably clamped by adjusting the limit sleeve 32 and the adjusting limit bolt 34. Then the inspection equipment is started to inspect the PCB board.

[0043] Inspection complete: After the inspection is completed, reverse start drive motor 13 to lower the stage and remove the PCB board; if you need to inspect PCB boards of different sizes, repeat the above steps.

[0044] The nano-lifting stage adjustment mechanism provided in this application can flexibly adjust the clamping gap by adjusting the relative position of the two adjusting limit sleeves 32 in the limiting mechanism 3. It can adapt to PCB boards of different sizes and specifications without changing the fixture, which significantly improves the versatility of the equipment. The position adjustment of the adjusting limit sleeves 32 can be achieved by loosening the adjusting locking bolts 33. After adjustment, the bolts can be tightened to fix it. The operation is simple and quick, which shortens the preparation time when changing PCB boards and improves the detection efficiency.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
