[0017] The present invention has the following beneficial effects:

[0018] (1) According to the present invention, after the hardware is clamped, the telescopic arm is started to move the telescopic shaft downward. The downward movement of the telescopic shaft will drive the obtuse-angle plate to move downward. The downward movement of the obtuse-angle plate will cause the sliding ring to drop a certain distance. Then, the telescopic shaft moving downward will cause the swing arm to change from an inclined state to a horizontal state. During the process of the swing arm changing from an inclined state to a horizontal state, the swing arm will also push against the obtuse-angle plate and rotate around the connection between the sliding ring and the obtuse-angle plate. When the swing arm becomes straight, the obtuse-angle plate will be expanded to block the detected part, thereby reducing the possibility that external light may interfere with the appearance of the hardware and cause misjudgment or missed detection. The sunshade mechanism can reduce the interference of external light and make the detection result more accurate.

[0019] (2) In the present invention, when the swing rod pushes against the obtuse-angled plate to expand the obtuse-angled plate, the push-pull rod will pull the sealing plate upward to move when the obtuse-angled plate expands. During the upward movement of the sealing plate, the teeth on the sliding rod will drive the gear shaft 1 to rotate, and the rotation of the gear shaft 1 will drive the reflective plate to rotate. When the push-pull rod moves the sealing plate upward to the top of the sliding groove, the reflective plate rotates forty-five degrees, refracting the light generated by the light source to the part to be detected of the hardware through the principle of refraction. The reflected light is used to enhance the illumination of the specific part, thereby reducing the generation of light and shadow, reducing the influence of light and shadow on the detector, and reducing the different degrees of illumination of different parts of the hardware, thereby enhancing the accuracy of the detection result.

[0020] (3) In the present invention, when the rotating rod is driven by the bevel gear to rotate, the rotating rod will cause the special-shaped sleeve to rotate through the belt. When the special-shaped sleeve rotates, the movable cylinder will be driven by the internally inserted rod to move forward under the action of the square block limit. When the movable cylinder moves to the leftmost end of the special-shaped sleeve, the movable cylinder will rotate through the square block. When the movable cylinder moves forward, the movable cylinder will move the rotating rod with the connecting plate 2 downward through the push rod, so that the center of the hardware is flush with the center of the hollow disk. Then the movable cylinder clamps the hardware through the hollow disk. When the hardware is clamped by the hollow disk, the hardware will move the circular plate backward. At this time, the transmission tooth plate will change from an inclined state to a vertical state. When the transmission tooth plate changes from an inclined state to a vertical state, the transmission tooth plate will cause the clamping tooth plate to move relatively through the gear shaft 2 to clamp the hardware to prevent it from falling off during detection.

[0021] (4) In the present invention, when the push rod moves downward against the second connecting plate, the top of the sponge stick moves to be flush with the bottom of the hardware. When the rotating stick is driven by the bevel gear to rotate, the sponge stick rotates. When the sponge stick rotates, it wipes the surface of the hardware to wipe off the dust on the surface of the hardware. Then, the rotating gear roller drives the fan at the bottom to rotate. When the fan rotates, a certain negative pressure is generated. At this time, the generation of negative pressure will draw the wiped dust to the outside of the device, reducing the occurrence of dust backflow. By wiping off the dust on the surface of the hardware, the situation of false detection caused by dust during detection can be reduced.

[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The reflection mechanism 3 includes a swing rod 301 fixedly connected to the fixed rod 207 and the rear wall, and the ends of the two swing rods 301 away from the fixed rod 207 are rotatably connected to an obtuse plate 302, and the top of the obtuse plate 302 is rotatably connected to the outer surface of the sliding ring 205. Two sliding grooves 303 are provided on one side of the obtuse plate 302 close to the swing rod 301, and the sliding groove 303 is slidably connected to a sliding rod 304 inside.

[0042] The side of the sliding rod 304 close to the swing rod 301 is fixedly connected to a sealing plate 305, the side of the sliding rod 304 close to the sealing plate 305 is fixedly connected to teeth, the inside of the obtuse-angled plate 302 is rotatably connected to two gear shafts 307, the opposite side of the two gear shafts 307 is fixedly connected to a reflective plate 306, the side of the sealing plate 305 away from the obtuse-angled plate 302 is rotatably connected to a push-pull rod 308, the top end of the push-pull rod 308 is rotatably connected to the outer surface of the sleeve 203, and an elastic shading cloth is fixedly connected between the two obtuse-angled plates 302.

[0043] A rotating mechanism 4 is provided inside the main body 1, and the rotating mechanism 4 includes a reinforcing plate 401 fixedly connected inside the square groove 101, a gear roller 402 is rotatably connected to the central axis of the reinforcing plate 401, a fan is fixedly connected to the bottom of the gear roller 402, and a small motor 403 is fixedly connected to the bottom of the reinforcing plate 401.

[0044] The output end of the small motor 403 is fixedly connected with a gear, which is meshed with the outer surface of the gear roller 402. The top of the gear roller 402 is fixedly connected with a transmission rod 1 404, and the outer surface of the transmission rod 1 404 is rotatably connected with a connecting rod 405. The left and right sides of the connecting rod 405 are rotatably connected with transmission rod 2 406, and the top of the transmission rod 2 406 is rotatably connected with a rotating shaft 407. The outer surface of the rotating shaft 407 is rotatably connected with a square plate, and the side of the square plate away from the transmission rod 1 404 is fixedly connected to the side wall of the rectangular groove 105. The outer surface of the rotating shaft 407 is slidably connected with a conical gear sleeve 408, and the bottom of the conical gear sleeve 408 is connected to the top of the square plate by a spring.

[0045] When in use, first place the hardware to be inspected on the sponge stick 505, then start the small motor 403. The rotation of the small motor 403 will cause the gear roller 402 to rotate. When the gear roller 402 rotates, the transmission rod 1 404 on its top will rotate back and forth with the transmission rod 2 406 at both ends through the connecting rod 405. Since the transmission rod 2 406 and the rotating shaft 407 are eccentric, when the transmission rod 2 406 rotates, the rotating shaft 407 will rotate in a circle and rotate with the conical gear sleeve 408. When the conical gear sleeve 408 rotates, The bevel gear 503 rotates with the rotating rod 501. After the hardware is clamped, the telescopic arm 201 is started to move the telescopic shaft 202 downward, which will drive the obtuse plate 302 to move downward. The downward movement of the obtuse plate 302 will bring the sliding ring 205 down a certain distance, and then the telescopic shaft 202 moving downward will cause the swing rod 301 to change from an inclined state to a horizontal state. In the process of the swing rod 301 changing from an inclined state to a horizontal state, the swing rod 301 will also push against the obtuse plate 302 to rotate around the connection between the sliding ring 205 and the obtuse plate 302. When the swing rod 301 becomes straight, the obtuse-angled plate 302 will be expanded to shield the detected part, reducing the interference of external light on the appearance of the hardware, resulting in misjudgment or missed detection. The sunshade mechanism 2 can reduce the interference of external light and make the detection result more accurate. When the swing rod 301 pushes the obtuse-angled plate 302 to expand the obtuse-angled plate 302, the push-pull rod 308 will pull the sealing plate 305 to move upward when the obtuse-angled plate 302 expands. During the upward movement of the sealing plate 305, the teeth on the sliding rod 304 will drive The gear shaft 307 rotates, and the rotation of the gear shaft 307 drives the reflector 306 to rotate. When the push-pull rod 308 moves the sealing plate 305 upward to the top of the sliding groove 303, the reflector 306 rotates forty-five degrees, and refracts the light generated by the light source 204 to the part to be detected of the hardware through the principle of refraction. The reflected light is used to enhance the illumination of the specific part, thereby reducing the generation of light and shadow, reducing the influence of light and shadow on the detector, and also reducing the different degrees of illumination of different parts of the hardware, thereby enhancing the accuracy of the detection result.

[0047] A moving mechanism 6 is provided on the top of the main body 1. The moving mechanism 6 includes a central axis 601 rotatably connected to the inside of the limit plate 106.

The outer surface of the square block 603 is slidably connected to a moving cylinder 604. Four plug rods are fixedly connected to the inner wall of the moving cylinder 604. The four plug rods are plugged into the inside of the special-shaped sleeve 602. The plug rods and the special-shaped sleeve 602 are slidably connected. The outer surface of the moving cylinder 604 is rotatably connected to two push rods 605. The two push rods 605 are symmetrically distributed around the central axis 601.

[0048] The special-shaped sleeve 602 is connected to the outer surface of the rotating rod 501 through a belt sleeve.

[0049] A fixing mechanism 7 is provided inside the moving mechanism 6, and the fixing mechanism 7 includes a hollow disk 701 fixedly connected to the side of the moving cylinder 604 away from the special-shaped sleeve 602, three connecting ears 702 are fixedly connected inside the hollow disk 701, and the connecting ears 702 are rotatably connected to the second gear shaft 703 inside.

The outer surface of the circular plate 704 is rotatably connected to three transmission tooth plates 705, and the transmission tooth plates 705 are meshingly connected to the second gear shaft 703.

[0050] A tensioning mechanism 8 is provided inside the main body 1, and the tensioning mechanism 8 includes two T-plates 801 fixedly connected to the inner wall at the top of the rectangular groove 105, a spring 2 is fixedly connected to the side of the T-plate 801 close to the belt, a C-block 802 is fixedly connected to the end of the spring 2 away from the T-plate 801, a fixing rod 803 is fixedly connected to the front and rear wall of the C-block 802, and the fixing rod 803 is slidably connected to the inside of the T-plate 801.

[0051] When in use, the rotation of the small motor 403 will cause the gear roller 402 to rotate. When the gear roller 402 rotates, the transmission rod 1 404 on its top will rotate back and forth with the transmission rod 2 406 at both ends through the connecting rod 405. Since the transmission rod 2 406 is eccentric to the rotating shaft 407, when the transmission rod 2 406 rotates, the rotating shaft 407 will rotate in a circle and rotate with the conical gear sleeve 408. When the conical gear sleeve 408 rotates, it will rotate with the rotating rod 501 through the conical gear 503. When the rotating rod 501 is driven by the conical gear 503, the rotating shaft 407 will rotate in a circle and rotate with the conical gear sleeve 408. When the rotating rod is driven by the shaped sleeve 602, the rotating rod 501 will rotate through the belt. When the shaped sleeve 602 rotates, the internally inserted rod will drive the moving cylinder 604 to move forward under the action of the square block 603. When the moving cylinder 604 moves to the leftmost end of the shaped sleeve 602, the moving cylinder 604 will rotate through the square block 603. When the moving cylinder 604 moves forward, the moving cylinder 604 will move the rotating rod 501 with the connecting plate 2 502 downward through the push rod 605, so that the center of the hardware is aligned with the center of the hollow disk 701. When the center of the hardware is flush, the moving cylinder 604 clamps the hardware through the hollow disk 701. When the hardware is clamped by the hollow disk, the hardware will move the circular plate 704 backward. At this time, the transmission tooth plate 705 will change from an inclined state to a vertical state. When the transmission tooth plate 705 changes from an inclined state to a vertical state, the transmission tooth plate will make the clamping tooth plate 706 move relatively through the gear shaft 2 703 to clamp the hardware to prevent it from falling off during detection. When the push rod 605 moves downward against the connecting plate 2 502, the top of the sponge stick 505 will move to the hardware. The bottom is flat, and when the rotating rod 501 is driven by the bevel gear 503 to rotate, the sponge rod 505 will rotate. When the sponge rod 505 rotates, it will wipe the surface of the hardware and wipe off the dust on the surface of the hardware. Then the rotating gear roller 402 will drive the fan at the bottom to rotate. When the fan rotates, a moving negative pressure will be generated. At this time, the generation of negative pressure will draw the wiped dust to the outside of the device, reducing the occurrence of dust reflux. By wiping off the dust on the surface of the hardware, the situation of false detection caused by dust during detection can be reduced.
