[0023] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0024] Embodiment 1, as Figures 1 - 5As shown in the figure, the present utility model provides a non-destructive metal detector with high detection accuracy, including: a detection component 1 and a base 4. A fixing component 3 is fixedly connected to the center position of the top of the base 4. A cleaning component 5 is arranged on the outer surface of the fixing component 3. A dust suction component 2 is fixedly connected to the top of the cleaning component 5; The cleaning component 5 includes a support frame 512. Symmetrically fixed connection mounting blocks 507 are arranged at the position near the left side of the top of the support frame 512. The rear surface of one of the mounting blocks 507 is fixedly connected with a motor 508, and the output end of the motor 508 penetrates through the rear surface of the mounting block 507 movably. The output end of the motor 508 is fixedly connected with a lead screw 503. A moving seat 504 is threadedly connected to the outer surface of the lead screw 503. The right surface of the moving seat 504 is rotatably connected with a rotating rod 510. A brush 509 is fixedly connected to the outer surface of the rotating rod 510. A gear 506 is fixedly connected to the outer surface of the rotating rod 510 near the left side. A tooth row 505 is fixedly connected to the top of the support frame 512 near the mounting block 507. The outer surface of the tooth row 505 is meshed with the outer surface of the gear 506. The front end surface of the lead screw 503 is rotatably connected to the outer surface of the other mounting block 507. Symmetrically fixed connection fixing blocks 502 are arranged at the position near the right side of the top of the support frame 512. A guide rod 501 is fixedly connected between the outer surfaces of the two fixing blocks 502. A sliding block 513 is movably connected to the outer surface of the guide rod 501. The left surface of the sliding block 513 is rotatably connected to the right end surface of the rotating rod 510. Symmetrically fixed connection electric telescopic rods 511 are arranged at the bottom of the support frame 512. The detection component 1 includes a top plate 101. A cross slide 102 is fixedly connected to the bottom of the top plate 101. A first electric push rod 103 is fixedly connected to the bottom of the cross slide 102. The driving end of the first electric push rod 103 is fixedly connected with a detector body 104. The fixing component 3 includes a support table 301. Clamping blocks 302 are symmetrically and movably connected to the inner surface of the support table 301. Second electric push rods 303 are symmetrically fixedly connected to the bottom of the support table 301. The driving ends of the two second electric push rods 303 are respectively fixedly connected to the outer surfaces of the two clamping blocks 302.

[0025] The effect achieved by the entire Example 1 is that all the electrical components in this text are electrically connected to an external controller. The cross slide 103 is a mechanical transmission device mainly used for precise linear motion. It includes two vertically intersecting sliding platforms, and realizes precise movement in two directions through a mutually perpendicular guide rail and slider system. When detecting a metal, place the metal on the support table 301, and then start two second electric push rods 303 to drive two clamping blocks 302 to move along the inside of the support table 301 to fix the metal. Then start the electric telescopic rod 511 to adjust the height of the support frame 512, thereby adjusting the distance between the brush bristles 509 and the metal surface to make them fit. After the adjustment is completed, start the motor 508 to drive the lead screw 503 to rotate along the mounting block 507, thereby driving the moving seat 504 to move back and forth. During the movement, since the rotating rod 510 is rotatably connected to the moving seat 504 and the gear 506 is meshed with the tooth row 505, it will drive the gear 506 to rotate along the tooth row 505, thereby driving the rotating rod 510 and the brush bristles 509 to rotate. And during the movement, with the cooperation of the sliding block 513 and the guide rod 501, the movement is made more stable, thereby driving the rotating rod 510 and the brush bristles 509 to rotate while moving, and fully cleaning the dust on the metal surface. After the cleaning is completed, reset the brush bristles 509, and then start the first electric push rod 103 to adjust the height of the detector body 104, so as to adapt to metals of different heights. At the same time, under the action of the cross slide 102, the position of the detector body 104 can be adjusted, which is convenient for detecting different positions of the metal through the detector body 104. By performing the cleaning work before detecting the metal, the cleanliness of the metal is guaranteed, interference signals can be reduced, and the defect recognition ability can be improved, thereby significantly improving the detection accuracy.

[0026] Example 2, as Figures 1 - 5 shown, the dust collection component 2 includes a dust collection hood 202 and an air pump 204. The top of the dust collection hood 202 is fixedly connected with a connecting pipe 205. The bottom of the connecting pipe 205 is fixedly connected with a corrugated pipe 201. The bottom of the corrugated pipe 201 is fixedly connected with a filter box 203. The input end of the air pump 204 is fixedly connected with the outer surface of the filter box 203. The bottom of the support table 301 is fixedly connected with the top center position of the base 4. The bottoms of the two electric telescopic rods 511 are both fixedly connected with the top of the base 4. The bottom of the dust collection hood 202 is fixedly connected with the tops of the sliding block 513 and the moving seat 504. The bottom of the top plate 101 is fixedly connected with the top of the base 4 through a round rod.

[0027] The effect achieved by the entire Embodiment 2 is that when cleaning the metal surface with the bristles 509, the dust suction hood 202 will move synchronously with the moving seat 504, and the air pump 204 can be started synchronously. Thus, under the cooperation of the corrugated pipe 201 and the connecting pipe 205, a negative pressure is generated in the dust suction hood 202 to suck the cleaned dust, avoiding secondary adhesion. Then, it enters the filter box 203 and is filtered by the air filter element in the filter box 203 to prevent impurities from damaging the air pump 204.

[0028] Working principle: When detecting the metal, place the metal on the support table 301. Then, by starting the two second electric push rods 303, drive the two clamping blocks 302 to move along the inside of the support table 301 to fix the metal. Then, start the electric telescopic rod 511 to adjust the distance between the bristles 509 and the metal surface to make them fit. After the adjustment is completed, start the motor 508 to drive the lead screw 503 to rotate along the mounting block 507, thereby driving the moving seat 504 to move back and forth. During the movement, since the rotating rod 510 is rotatably connected to the moving seat 504 and the gear 506 is meshed with the tooth row 505, the gear 506 will be driven to rotate along the tooth row 505, thereby driving the rotating rod 510 and the bristles 509 to rotate. And during the movement, with the cooperation of the sliding block 513 and the guide rod 501, the movement is made more stable, so as to drive the rotating rod 510 and the bristles 509 to rotate while moving, and thoroughly clean the dust on the metal surface. When cleaning the metal surface with the bristles 509, the air pump 204 can be started synchronously. Thus, under the cooperation of the corrugated pipe 201 and the connecting pipe 205, a negative pressure is generated in the dust suction hood 202 to suck the cleaned dust, avoiding secondary adhesion. After the cleaning is completed, reset the bristles 509, and then start the first electric push rod 103 to adjust the height of the detector body 104, so as to adapt to metals of different heights. At the same time, under the action of the cross slide table 102, the position of the detector body 104 can be adjusted to facilitate the detection of different positions of the metal. By performing the cleaning work before detecting the metal, the cleanliness of the metal is ensured, interference signals can be reduced, the defect recognition ability can be improved, and thus the detection accuracy can be significantly improved.

[0029] The wiring diagrams of the first electric push rod 103, the cross slide table 102, the detector body 104, the air pump 204, the second electric push rod 303, the motor 508, and the electric telescopic rod 511 in the present utility model belong to the common knowledge in the art. Their working principles are already well-known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the first electric push rod 103, the cross slide table 102, the detector body 104, the air pump 204, the second electric push rod 303, the motor 508, and the electric telescopic rod 511 will not be explained in detail.
