During the movement of the limiting ring 407, it drives the second moving block 406 to move along the axial direction of the slide rod 405. When the limiting ring 407 moves to a suitable position, the first screw rod 403 stops rotating. Since the screw rod has a self-locking feature, the limiting ring 407 does not change during the material transportation process. The slide rod 405 fixed in the remaining first moving groove 402 and the second moving block 406 on its outer surface provide stable support for the limiting ring 407.

[0023] like Figure 6-7As shown, the detection assembly 7 includes a workbench 701, and four fixing plates 702 are fixedly installed on the upper surface of the workbench 701. The four fixing plates 702 are symmetrically distributed about the center line of the workbench 701. A second screw rod 703 is provided between two left-right symmetrical fixing plates 702. The second screw rod 703 is rotatably connected to the two fixing plates 702. A slider 704 is sleeved on the outer surface of the second screw rod 703. A third screw rod 705 is rotatably installed between the two sliders 704. The outer surface of the third screw rod 705 is sleeved with Camera module 706, a light-emitting panel 707 is fixedly installed on the upper surface of the workbench 701 corresponding to the camera module 706, the second screw rod 703 and the third screw rod 705 are both connected to an external power source, the second screw rod 703 controls the camera module 706 to translate in the length direction of the material by rotation, and the third screw rod 705 controls the camera module 706 to move in the width direction of the material by rotation, the camera module 706 takes pictures of the surface of the material, and the reflector enhances the black and white characteristics of the material itself.

Two first sliding grooves 711 are provided on the upper surface of the workbench 701 corresponding to the side plates 708. The two first sliding grooves 711 are symmetrically distributed about the center line of the workbench 701. A double-headed screw 712 is rotatably installed on the inner wall of the first sliding groove 711, and two movable plates 713 are sleeved on the outer surface of the double-headed screw 712. The two movable plates 713 are symmetrically distributed about the center line of the double-headed screw 712, and a limiting plate 714 is fixedly installed on the upper surface of the movable plate 713. The fourth screw rod 709 is externally connected to a power source, and the fourth screw rod 709 and the double-headed screw 712 are both externally connected to a power source. The fourth screw rod 709 rotates to allow the detection unit 710 to move along the width of the material. The material is preliminarily inspected in the direction. When inspecting different materials, the double-headed screw 712 rotates to make the two movable plates 713 approach or separate from each other along the axial direction of the double-headed screw 712. The limit plate 714 limits the height of the material. The model of the detection unit 710 is FH-2050. FH-2050 obtains the image of the object to be detected through an integrated camera or an external image acquisition device. These images can be static or dynamic. After the image acquisition is completed, FH-2050 will pre-process the image to remove noise, enhance contrast, adjust brightness, etc., so as to improve the image quality and lay the foundation for subsequent detection and analysis. FH-2050 uses the built-in image processing algorithm to conduct in-depth analysis of the pre-processed image and identify the key features and structures in the image. Based on the extracted feature information, FH-2050 will use machine learning or deep learning algorithms to detect the target objects in the image. It can identify whether there is a preset target object in the image and determine its approximate location. After detecting the target object, FH-2050 will further accurately locate the target object.

[0024] like Figure 8As shown, the collecting assembly 9 includes a rotating shaft 901, and two rotating shafts 901 are provided. A rotating plate 902 is fixedly installed at one end of the two rotating shafts 901 close to each other. A plurality of stopper tubes 903 are rotatably installed on one side of the two rotating plates 902 close to each other. The plurality of stopper tubes 903 are distributed around the center line of the rotating plate 902. A collecting tube 904 is provided between the two corresponding stopper tubes 903. The end surface of the stopper tube 903 close to one end of the collecting tube 904 is provided with a plurality of insertion holes. The plurality of insertion grooves 905 are distributed around the center line of the limiting tube 903. A second slide groove 906 corresponding to the insertion groove 905 is provided inside the collecting tube 904. A circular plate 907 is fixedly installed on the inner wall of the collecting tube 904 corresponding to the second slide groove 906. A top plate 908 is provided inside the second slide groove 906. A guide rod 909 is fixedly installed on one side of the circular plate 907 close to the top plate 908. A second spring 910 is sleeved on the outer surface of the guide rod 909. Both ends of the second spring 910 are fixedly installed on the inner wall of the collecting tube 904. The top plate 908 is fixedly connected to the surface of the circular plate 907 and the bottom surface of the top plate 908 respectively. An insertion rod 912 corresponding to the insertion groove 905 is fixedly installed on the side of the top plate 908 away from the circular plate 907. When the material on the collection tube 904 is collected, the staff squeezes the top plate 908 to make the insertion rod 912 on the top plate 908 leave the corresponding insertion groove 905, and the collection tube 904 can be quickly removed. When the collection tube 904 is connected to the limiting tube 903, the second spring 910 makes the insertion rod 912 stably fixed. The limiting tube 903 is fixed and inserted into the groove 905, thereby realizing the connection between the limiting tube 903 and the collecting tube 904. The rotating shaft 901 and the limiting tube 903 are both connected to an external power source. When collecting materials, the limiting tube 903 drives the collecting tube 904 to rotate by rotation so that the materials are wound around the surface of the collecting tube 904. When the materials are fully wound, the staff cuts the materials. At the same time, the rotating shaft 901 rotates to move the remaining collecting tubes 904 to the appropriate position, and the materials are connected to the corresponding collecting tubes 904.

[0025] like Figure 6 As shown, a buffer plate 17 is fixedly installed on one side of the side plate 708 close to the detection unit 710. During the movement of the detection unit 710, the direct contact between the side plate 708 and the detection unit 710 may cause damage or wear to the detection unit 710. The setting of the buffer plate 17 can effectively isolate the direct contact between the side plate 708 and the detection unit 710, thereby protecting the lens, sensor and other precision components of the detection unit 710 from damage.

[0026] like Figure 5As shown, a clearance fit is adopted between the extrusion plate 603 and the fixing rod 601, and the fitting tolerance is 1mm-2mm. The clearance fit allows a certain amount of movable space for the extrusion plate 603 on the fixing rod 601, so that the cleaning roller 602 can be adaptively adjusted according to different diaphragm thicknesses and surface conditions. When the diaphragm passes through, the extrusion plate 603 can move slightly to ensure that the cleaning roller 602 always maintains an appropriate contact pressure with the diaphragm, thereby improving the cleaning effect.

[0027] A method for using a diaphragm shadow detection device comprises the following steps: S1: Preparation work before material inspection, the first screw rod 403 rotates to make the first moving block 404 drive the limiting ring 407 to move along the axial direction of the support rod 401, and the limiting ring 407 drives the second moving block 406 to move along the axial direction of the slide rod 405 during the movement. When the limiting ring 407 moves to the appropriate position, the first screw rod 403 stops rotating, and at the same time, the double-headed screw 712 rotates to make the moving plate 713 move to the appropriate position.

[0028] S2: During the operation of the equipment, the material passes through the support rod 401, a plurality of first reversing rods 5, the cleaning roller 602, the workbench 701, the second reversing rod 8 and the collection pipe 904 in sequence.

[0029] S3: When the detection component 7 is detecting the material, the second screw rod 703 controls the camera module 706 to translate in the length direction of the material by rotation, and the third screw rod 705 controls the camera module 706 to move in the width direction of the material by rotation. The camera module 706 takes pictures of the surface of the material, and at the same time, the fourth screw rod 709 rotates to enable the detection unit 710 to perform preliminary detection of the material along the width direction of the material.

[0030] S4: When collecting materials, the staff cuts the materials, and at the same time, the rotating shaft 901 rotates to move the remaining collection tubes 904 to the appropriate position, and the collection tube 904 can be quickly removed by squeezing the top plate 908 so that the insertion rod 912 on the top plate 908 leaves the corresponding insertion slot 905, and the collection tube 904 can be placed in the corresponding position. When the collection tube 904 is connected to the limiting tube 903, the second spring 910 makes the insertion rod 912 stably fixed in the insertion slot 905, thereby realizing the connection between the limiting tube 903 and the collection tube 904.

[0031] S5: When maintaining the equipment, the staff presses the extrusion plate 603 so that the extrusion plate 603 pushes the first spring 604 to deform. When the extrusion plate 603 leaves the fixed rod 601, the cleaning roller 602 is removed and a new cleaning roller 602 is placed on the outer surface of the fixed rod 601. After the new cleaning roller 602 is installed, the first spring 604 pushes the extrusion plate 603 to combine with the fixed rod 601 in real time.

[0032] Working principle: In the preparation work before material detection, the first screw rod 403 rotates to make the first moving block 404 drive the limiting ring 407 to move along the axial direction of the support rod 401. During the movement of the limiting ring 407, the second moving block 406 is driven to move along the axial direction of the slide rod 405. When the limiting ring 407 moves to the appropriate position, the first screw rod 403 stops rotating, and at the same time, the double-headed screw 712 rotates to make the moving plate 713 move to the appropriate position; during the operation of the equipment, the material passes through the support rod 401, a plurality of first reversing rods 5, the cleaning roller 602, the workbench 701, the second reversing rod 8 and the collecting tube 904 in sequence. When the detection component 7 detects the material, the second screw rod 703 controls the camera module 706 to translate in the length direction of the material by rotation, and the third screw rod 705 controls the camera module 706 to move in the width direction of the material by rotation. The camera module 706 takes pictures of the surface of the material, and at the same time, the fourth screw rod 709 rotates to make the detection unit 710 move in the width direction of the material.
