[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution for a defect detection device in the wire drawing process: it includes a detection device body 1, a detection hole 2 on the detection device body 1, and a sealing mechanism on the detection device body 1. The sealing mechanism includes a dual-axis electric push rod 3 fixedly connected to the upper end of the detection device body 1. L-shaped plates 4 are connected to the two output shafts of the dual-axis electric push rod 3. First wire holes 5 are opened on the two L-shaped plates 4, and the positions of the two first wire holes 5 correspond to the detection hole 2. A drive gear 6 is rotatably connected inside the L-shaped plate 4, and a rack 7 is slidably connected inside the L-shaped plate 4. A sealing plate 8 is fixedly connected to the lower end of the rack 7. The sealing plate 8 can close the first wire holes 5. The drive gear 6 meshes with the rack 7. When the wire is detected by the detection device body 1, the wire to be detected can be projected onto the surface of the wire through the detection hole 2 by an infrared light source. The reflected light signal is captured by an optical sensor, and the surface unevenness is analyzed, which achieves a good detection effect.

[0024] The closing mechanism also includes an embedded column 10 fixedly connected to the drive gear 6. An embedded groove 9 is provided on the main body 1 of the detection device. The embedded column 10 can be inserted into the inside of the embedded groove 9. The embedded column 10 can move inside the embedded groove 9, but cannot be completely removed from the inside of the embedded groove 9. It can play a certain connecting role for the main body 1 of the detection device and the L-shaped plate 4.

[0025] The closing mechanism also includes a spiral groove 11 formed inside the embedding groove 9. A limiting block 12 is fixedly connected to the outer wall of the embedding post 10. The limiting block 12 is located inside the spiral groove 11. When the embedding post 10 moves inside the embedding groove 9, the limiting block 12 will also move inside the spiral groove 11. Under the limiting of the spiral groove 11, the embedding post 10 can rotate based on the embedding groove 9 to realize the rotation of the drive gear 6, thereby realizing the movement of the closing plate 8 and completing the opening and closing of the first wire hole 5.

[0026] The diameter of the first hole 5 is larger than the diameter of the detection hole 2. The two L-shaped plates 4 can completely seal the detection hole 2. The two L-shaped plates 4 can completely seal the detection hole 2 from the front, rear and top of the main body 1 of the detection device, preventing dust from entering the interior of the detection hole 2. It does not require staff to clean it regularly, which is very convenient.

[0027] A cleaning mechanism is provided on the L-shaped plate 4. The cleaning mechanism includes a U-shaped plate 13 fixedly connected to the L-shaped plate 4. A second wire hole 14 is opened on the U-shaped plate 13. An arc-shaped strip 17 is connected to the inside of the second wire hole 14 through a spring column 16. A rolling column 15 is rotatably connected to the U-shaped plate 13. The rolling column 15 is located inside the second wire hole 14. Under the action of the spring column 16, the arc-shaped strip 17 can be attached to wires of different thicknesses, so that the wires of different thicknesses can be fixed as much as possible at the center of the detection hole 2, which facilitates the detection work.

[0028] The diameter of the second wire hole 14 is slightly larger than the diameter of the detection hole 2. The outer wall of the rolling column 15 is provided with bristles, and the concave surface of the arc strip 17 is also provided with bristles. The surface of the wire can be cleaned by the bristles to prevent dust from entering the interior of the detection device body 1 along with the wire. This ensures the accuracy of the detection and also provides good protection for the detection device body 1.

[0029] A base 21 is fixedly installed at the lower end of the main body 1 of the testing device. A display screen 18 and an adjustment knob 19 are provided on the right side wall of the main body 1 of the testing device. A connector 20 is provided on the left side wall of the main body 1 of the testing device. The entire main body 1 of the testing device can be installed through the base 21 to facilitate the testing work. The display screen 18 can be used to view relevant values ​​and testing status in real time. The adjustment knob 19 can be used to set the working status of the main body 1 of the testing device. The connector 20 can be used to connect the main body 1 of the testing device to external devices and provide power.

[0030] The working principle of this utility model is as follows: When wire needs to be tested, the dual-axis electric push rod 3 first starts working, thereby pushing the two L-shaped plates 4 away from the main body 1 of the testing device. During the movement of the L-shaped plates 4 based on the main body 1 of the testing device, the embedded post 10 also moves out of the embedded groove 9. At this time, under the action of the spiral groove 11 and the limiting block 12, the embedded post 10 will rotate based on the embedded groove 9. When the embedded post 10 rotates, it will drive the drive gear 6 to rotate synchronously, and then drive the rack 7 meshing with it to move upward. When the rack 7 moves, it can synchronously drive the closing plate 8 to move upward. When the closing plate 8 moves to the top, the first wire hole 5 can be opened, and the testing hole 2 can be exposed for testing. At this time, the wire to be tested can be... The wire extends into the detection hole 2 through the first wire hole 5 and the second wire hole 14 for detection. When the wire passes through the second wire hole 14, the rotatable rolling column 15 facilitates the movement of the wire inside the second wire hole 14. At the same time, under the action of the spring column 16, the arc strip 17 adheres to the surface of the wire, so that the wire is located as close as possible to the center of the detection hole 2, avoiding the wire surface from contacting the inside of the detection hole 2 and affecting the detection. At the same time, the brush bristles on the rolling column 15 and the arc strip 17 can clean the dust on the wire and prevent dust from entering the interior of the detection device body 1. After use, the dual-axis electric push rod 3 returns to its original position, completing the sealing of the detection hole 2 and preventing dust from entering the interior of the detection device body 1 when not in use, thus providing a good protective effect.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
