[0020] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0021] Example: A fixed positioning device for foreign object detection in quartz resonators, such as... Figures 1-4 As shown, the device includes a testing platform 1, a camera 2, a rotating disk 3, a movable base 4, fixed rods 5, a rubber band 6, a control component, and an adjustment component.

The first hydraulic cylinder 7 and the second hydraulic cylinder 9 are installed inside the testing platform 1, and the volume of the second hydraulic cylinder 9 is larger than that of the first hydraulic cylinder 7. The piston rods at both ends of the first hydraulic cylinder 7 are connected to the movable base 4. One end of each of the two hoses 8 is connected to both ends of the second hydraulic cylinder 9, and the other end of the hoses 8 is connected to the middle of the first hydraulic cylinder 7. The screw 13 is rotatably connected inside the second hydraulic cylinder 9. The threads on both sides of the screw 13 are in opposite directions. The sealing rod 131 is threadedly connected to both ends of the screw 13. Since the sealing rod 131 has a notch that cooperates with the second hydraulic cylinder 9, the sealing rod 131 is slidably connected inside the second hydraulic cylinder 9. The first handwheel 10 is rotatably connected to the testing platform 1. The bottom of the first handwheel 10 is connected to the worm gear 11, and the middle of the screw 13 is connected to the worm wheel 12. The worm wheel 12 and the worm gear 11 are driven together.

[0024] The staff rotates the first hand wheel 10, moves the mobile base 4 through the control assembly, after the mobile base 4 approaches each other, the rubber belt 6 on the fixed rod 5 clamps the quartz resonator, then the quartz resonator is observed through the camera 2, and the second hand wheel 16 is rotated, the rotating disc 3 is rotated through the adjusting assembly, the angle of observation is adjusted, so as to ensure the comprehensive inspection, after the inspection is completed, the first hand wheel 10 is reversely rotated, the mobile base 4 is moved to the two sides through the control assembly, the quartz resonator is released, and the detection process of one quartz resonator is completed.

[0025] When the first hand wheel 10 is rotated to the right side, the worm 11 rotates with the first hand wheel 10, so as to drive the worm wheel 12 to rotate, the worm wheel 12 drives the screw rod 13 to rotate, the screw rod 13 pushes the sealing rod 131 to move to the middle, so that the second hydraulic cylinder 9 extracts the liquid in the first hydraulic cylinder 7 through the hose 8, the piston rods at the two ends of the first hydraulic cylinder 7 slide to the middle, pull the mobile base 4 to move to the middle, after the rubber belt 6 contacts the quartz resonator, the mobile base 4 continues to move, the rubber belt 6 is clamped and fixed on the quartz resonator under the pull of the fixed rod 5, and when the first hand wheel 10 is rotated to the left side, the sealing rod 131 is pushed to the two sides through the screw rod 13, the liquid is extruded to pass through the hose 8 and enter the first hydraulic cylinder 7, then the first hydraulic cylinder 7 pushes the mobile base 4 to move to the two sides and releases the quartz resonator;

[0026] When the second hand wheel 16 is rotated, the second hand wheel 16 drives the first gear 14 to rotate, the first gear 14 drives the rotating disc 3 to rotate through the second gear 15 engaged with the first gear 14, so as to adjust the position of the camera 2 for shooting the quartz resonator, and facilitate the comprehensive observation and detection of the quartz resonator, in the rotating process of the rotating disc 3, the hose 8 rotates with the rotating disc 3, and the length reserved for the hose 8 is enough for the rotating disc 3 to rotate one circle.

[0027] As shown in Figure 1 and Figure 2 It also comprises a collection box 17, and the left and right sides of the detection table 1 are provided with the collection box 17 which can be pulled out.

[0028] The collection box 17 is placed with the components such as the rubber belt 6 which are consumed, and the necessary tools for replacing the components, so as to ensure the normal work of the equipment.

[0030] The adjusting feet 18 can adjust the height of the detection table 1 to ensure that it is kept horizontal on different planes.

[0031] As shown in Figure 1 and Figure 2 , the device further comprises a protective cover 19, which is clamped on the detection table 1 and has an inner diameter greater than the diameter of the rotating disc 3 and a height greater than the height of the fixed rod 5.

[0032] The protective cover 19 is removed when the device is in use and is covered when it is idle, which can protect the device from external environmental interference.

[0033] As shown in Figure 2 , the device further comprises an illuminating lamp 20, which is installed in the middle of the rotating disc 3 to supplement light.

[0034] The illuminating lamp 20 is turned on during the detection process to illuminate the quartz resonator from the bottom, which facilitates observation of the detection.

[0035] The staff rotates the first hand wheel 10 to drive the worm 11 to rotate, which in turn drives the worm gear 12 and the screw rod 13 to rotate, and the rotation of the screw rod 13 drives the sealing rod 131 to move to the middle or both sides in the second hydraulic cylinder 9. Through the communication effect of the hose 8 and the first hydraulic cylinder 7, the extension and retraction of the piston rod of the first hydraulic cylinder 7 is controlled, so as to pull or push the moving base 4 to slide on the rotating disc 3. The opposite movement of the moving base 4 makes the rubber belt 6 between the fixed rods 5 clamp the quartz resonator, ensuring its stability during the detection process. At the same time, the camera 2 is installed on the detection table 1 to capture the image of the quartz resonator. In order to adjust the observation angle, the staff rotates the second hand wheel 16 to drive the first gear 14 to rotate, which drives the rotating disc 3 and the clamped quartz resonator to rotate through the meshing of the first gear 14 and the second gear 15, ensuring that the camera 2 can observe all areas of the quartz resonator. In addition, the device is also equipped with an illuminating lamp 20 to provide supplemental light for the quartz resonator from the bottom, enhancing the detection effect. After the detection is completed, the first hand wheel 10 is rotated in the opposite direction to release the clamping of the quartz resonator by the rubber belt 6, completing a single detection process. The collection box 17 is used to store consumables such as the rubber belt 6 and replacement tools, and the adjusting feet 18 ensure that the detection table 1 is placed horizontally on different planes. The protective cover 19 provides protection when the device is idle to prevent external interference.
