Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] Please see Figure 1-6 This utility model provides a technical solution:

[0029] A novel fully enclosed automatic edge-finding and alignment device includes a conveying device 1 and a roller assembly 4. A base 2 is fixedly connected to the right side of the conveying device 1, and a protective housing assembly 3 is fixedly connected to the top of the base 2. A photoelectric detection assembly 5 is slidably connected to the inside of the protective housing assembly 3, and the roller assembly 4 is rotatably connected to the inside of the photoelectric detection assembly 5. The protective housing assembly 3 includes a protective shell 31, with a shaft hole 32 at one end. A rubber sealing ring 33 is fixedly connected to the inside of the shaft hole 32 in the protective shell 31, and a track groove 34 is formed inside the protective shell 31. An electric telescopic rod 35 is fixedly connected to the inner side of the protective shell 31 near the lower end. An auxiliary detection block 36 is fixedly connected to the inner side of the protective shell 31. The photoelectric detection component 5 includes a sleeve block 51. A rail plate 52 is fixedly connected to the front and rear ends of the sleeve block 51. A through hole 53 is opened on the inner side of the sleeve block 51. A ball bearing 54 is fixedly connected to the inner side of the through hole 53 of the sleeve block 51. A push plate 55 and a photoelectric sensor 56 are fixedly connected to the bottom end of the sleeve block 51. The bottom end of the protective shell 31 is fixedly connected to the top end of the base 2. The rail plate 52 is slidably connected to the inner side of the rail groove 34 opened in the protective shell 31.

[0030] As a further implementation of this solution, there are two protective box components 3. The inner side of the protective shell 31 is hollow, and the shaft hole 32 passes through the left end of the protective shell 31. The front and rear ends of the protective shell 31 are provided with rail grooves 34. The photoelectric detection component 5 is embedded and installed inside the protective shell 31. Through the above settings, space is provided for the movement of the components and signal transmission, while enhancing the compactness and flexibility of the device. The rail grooves 34 serve to limit the movement of the photoelectric detection component 5.

[0031] As a further implementation of this solution, the roller assembly 4 includes a rubber cylinder 41. An air bladder 42 and a rubber support plate 43 are fixedly connected to the inner side of the rubber cylinder 41. One side of the air bladder 42 and the rubber support plate 43 are fixedly connected to the outer side of the metal roller 44. Extension columns 45 are fixed on both the left and right sides of the metal roller 44. The outer side of the rubber cylinder 41 is in close contact with the inner side of the conveyor belt of the conveyor device 1 near the upper end. The extension column 45 is cylindrical in shape. The outer side of the extension column 45 is in contact with the inner side of the rubber sealing ring 33. The extension column 45 is embedded in the inner side of the shaft hole 32. Through the above arrangement, the connection stability between the rubber cylinder 41 and the metal roller 44 is enhanced, ensuring that the rubber cylinder 41 can stably drive the metal roller 44 and the extension column 45 to rotate when the conveyor belt rotates. This improves the operational reliability of the device, ensures good contact between the rubber cylinder 41 and the conveyor belt, increases friction, and ensures that the rubber cylinder 41 can rotate stably with the conveyor belt. At the same time, the embedded installation enhances the stability of the structure.

[0032] As a further implementation of this solution, a controller 6 is fixedly connected to one side of the base 2. The controller 6 is electrically connected to the photoelectric sensor 56 and the electric telescopic rod 35. Through the above settings, the controller 6 serves as the transmission hub for signals and power, realizing the electrical connection between the photoelectric sensor 56 and the electric telescopic rod 35, and ensuring the stability and reliability of signal transmission.

[0033] As a further implementation of this solution, the outer side of the extension column 45 is fixedly connected to the inner side of the ball bearing 54, and the center of the through hole 53 of the protective box assembly 3 and the center of the shaft hole 32 are on the same horizontal line. Through the above settings, the stable rotation between the extension column 45 and the ball bearing 54 is ensured, and the friction during the rotation process is reduced.

[0034] As a further implementation of this solution, the photoelectric sensor 56 and the auxiliary detection block 36 are on the same vertical plane. Two push plates 55 are fixed at the lower end of the sleeve block 51, and the photoelectric sensor 56 is located between the two push plates 55. Two electric telescopic rods 35 are fixed inside the protective shell 31. The positions of the electric telescopic rods 35 are aligned with the positions of the push plates 55. Through the above settings, the alignment design and the vertical plane layout optimize the signal detection path and achieve the effect of correcting the conveyor belt of the conveyor device 1.

[0035] Workflow: While correcting the conveyor belt of conveyor device 1 and preventing dust from affecting the detection performance of photoelectric sensor 56, rubber sealing ring 33 seals the extension column 45 and protective shell 31, preventing dust from entering the interior of protective shell 31 and thus preventing dust from contacting photoelectric sensor 56, which could weaken or distort the detection signal. When the conveyor belt of conveyor device 1 rotates, the rubber cylinder 41 rotates due to its close contact with the outside of the conveyor belt. During rotation, the rubber cylinder 41, air bladder 42, and rubber support plate 43 undergo deformation. The rubber support plate 43 supports the rubber cylinder 41 and the metal roller 44. The expansion of air bladder 42 increases the friction between the rubber cylinder 41 and the conveyor belt of conveyor device 1, ensuring the effectiveness of the rubber cylinder 41 rotating with the conveyor belt. The rubber cylinder 41 drives the metal roller 44 and extension column 45 to rotate via air bladder 42 and rubber support plate 43. The extension column 45 rotates via ball bearings. The bearing 54 is rotatably connected to the through hole 53. The ball bearing 54 reduces the friction when the roller assembly 4 rotates. When the conveyor belt of the conveyor device 1 deviates, the roller assembly 4 will drive the sleeve block 51 to move. The sleeve block 51 slides on the inside of the groove 34 opened in the protective shell 31 through the rail plate 52. The photoelectric detection assembly 5 moves as a whole. At this time, the light emitted by the photoelectric sensor 56 will move when it shines on the upper part of the auxiliary detection block 36. The controller 6 transmits the signal to the photoelectric sensor 56 to determine whether the conveyor device 1 deviates. The controller 6 then controls the electric telescopic rod 35 at the left or right end inside the protective shell 31 to push the push plate 55 to move. The photoelectric detection assembly 5 drives the roller assembly 4 to move. Under the action of the friction between the roller assembly 4 and the conveyor belt of the conveyor device 1, the conveyor belt of the conveyor device 1 is corrected. The device changes the object detected by the photoelectric sensor 56 and puts the photoelectric sensor 56 in a sealed environment, which greatly reduces the impact on the detection accuracy of the photoelectric sensor 56.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
