[0023] The support frame 2 is in the shape of an inverted U.

[0024] It can be understood that one end of the high-precision plate decorative paper roll is pulled into the belt conveying frame 1, at this time, the winding roller rotates in the circular groove and is detected by the camera 4, a winding roller is arranged at the right side of the belt conveying frame 1, one end of the detected paper roll is fixed to the winding roller, so that the detected high-precision plate decorative paper roll can be wound on the winding roller.

[0025] Please refer to Figure 2 In order to clean the surface protection glass of the camera 4, the cleaning mechanism 6 in the embodiment comprises a fixed box 601 fixed to the upper surface of the frame body and located at the right side of the support frame 2, a fixed groove 602 is formed in the top of the left side of the fixed box 601, an electric push rod 603 is fixed to the right side wall in the inner cavity of the fixed groove 602, mounting plates 604 are fixed to the bottoms of the left and right ends of the inner vertical wall of the fixed groove 602, a connecting rod 605 is fixed between the opposite sides of the two mounting plates 604, a limiting sleeve 606 is slidably connected to the outer surface of the connecting rod 605, a linkage frame 607 is fixed to the upper surface of the limiting sleeve 606, the electric push rod 603 is started, the piston rod of the electric push rod 603 is elongated to push the linkage frame 607 to move leftward, the movement of the linkage frame 607 makes the limiting sleeve 606 slide leftward on the outer surface of the connecting rod 605, a fixed plate 608 is fixed to the upper surface of the linkage frame 607, cleaning cotton 609 is fixed to the upper surface of the fixed plate 608, the movement of the linkage frame 607 synchronously drives the fixed plate 608 and the cleaning cotton 609 to move leftward, so that the cleaning cotton 609 contacts the surface protection glass, at this time, the surface protection glass of the camera 4 can be cleaned, then the electric push rod 603 is shortened, so that the cleaning cotton 609 moves rightward, and the surface protection glass of the camera 4 can be cleaned back and forth.

[0026] After cleaning, the piston rod of the electric push rod 603 is shortened, and the linkage frame 607 drives the fixed plate 608 to completely move into the inner cavity of the fixed groove 602, so as to avoid shielding the shooting range of the camera 4.

[0027] Among them, the piston rod of the electric push rod 603 is fixed to the linkage frame 607. The cross-sectional shape of the top of the linkage frame 607 is T-shaped, and the cross-sectional shape of the bottom of the linkage frame 607 is inverted S-shaped. The size of the cleaning cotton 609 is larger than the size of the camera 4.

[0028] In addition, the cross-sectional shape of the fixing box 601 is an inverted L shape, and the fixing method between the fixing plate 608 and the cleaning cotton 609 is a Velcro structure. The upper surface of the fixing plate 608 is fixed with a female Velcro, and the lower surface of the cleaning cotton 609 is fixed with a female Velcro, which makes it convenient for staff to replace the cleaning cotton 609 at regular intervals.

[0029] It should be noted that this allows staff to clean the protective glass on the surface of camera 4 regularly, preventing dust from affecting the clarity and quality of the image and improving the accuracy of camera 4 in detecting defects on the surface of high-precision decorative paper.

[0030] Please see Figures 3-4 To accommodate rollers of different sizes, the disassembly and assembly mechanism 7 in this embodiment includes a support plate 701 fixed to the left side of the frame. A mounting groove 702 is provided at the front end of the upper surface of the support plate 701. A limit rod 703 is fixed at the left end between the opposite sides of the front and rear side walls of the mounting groove 702. A threaded rod 704 is rotatably connected via a bearing between the opposite sides of the front and rear side walls of the mounting groove 702 and to the right of the limit rod 703. A sliding sleeve 705 is slidably connected to the outer surface of the limit rod 703. The outer surface of the device is threaded with a threaded sleeve 706. A linkage plate 707 is fixed between the sliding sleeve 705 and the opposite side of the threaded sleeve 706. When the rotating motor is started, the output shaft of the rotating motor rotates, which drives the threaded rod 704 to rotate, thereby causing the threaded sleeve 706 threaded to move forward. The movement of the threaded sleeve 706 can drive the linkage plate 707 and the sliding sleeve 705 to move, thereby causing the sliding sleeve 705 to slide on the outer surface of the limiting rod 703, which can limit the movement of the threaded sleeve 706, so that it can only perform linear movement.

[0031] The support plate 701 has a first positioning plate fixed to the rear end of its upper surface, and a second positioning plate fixed to the upper surface of the linkage plate 707. The top of the first and second positioning plates on opposite sides is provided with a circular groove. The support plate 701 has a rotating motor fixed to its front side. The output shaft of the rotating motor passes through and extends into the inner cavity of the mounting groove 702 and is fixed to the threaded rod 704.

[0032] Understandably, the movement of the linkage plate 707 causes the second positioning plate to move away from the first positioning plate until the distance between the opposite sides of the circular grooves on the first and second positioning plates is greater than the length of the roll in the high-precision decorative paper roll. One side of the roll is then placed into the circular groove of the first positioning plate. Then, the output shaft of the drive motor is reversed, which causes the second positioning plate to move closer to the first positioning plate until the circular groove of the second positioning plate fits over the roll.

[0033] It should be noted that this design facilitates the placement of the high-precision decorative paper roll into the inner cavities of the first and second positioning plates. This not only makes it easier to disassemble the roll but also allows for the adaptation to rolls of different sizes, improving flexibility and applicability.

[0034] All electrical components mentioned in this document are electrically connected to the main controller and power supply, and all electrical components mentioned in this document are conventional and known devices. This application will not elaborate further. The main controller can be a conventional and known device such as a computer that performs control. The control circuit of the main controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this application is mainly used to protect mechanical devices, so this application will not explain the control method and circuit connection in detail.

[0035] The working principle of the above embodiments is as follows:

[0036] (1) When cleaning the surface of the camera 4, first start the electric push rod 603. The piston rod of the electric push rod 603 extends and pushes the linkage frame 607 to move to the left. The movement of the linkage frame 607 causes the limit sleeve 606 to slide to the left on the outer surface of the connecting rod 605. The movement of the linkage frame 607 simultaneously drives the fixing plate 608 and the cleaning cotton 609 to move to the left, so that the cleaning cotton 609 contacts the protective glass. At this time, the protective glass on the surface of the camera 4 can be cleaned. Then the electric push rod 603 shortens, which allows the cleaning cotton 609 to move to the right. The protective glass on the surface of the camera 4 can be cleaned back and forth. After cleaning, the piston rod of the electric push rod 603 can be shortened, and the linkage frame 607 can drive the fixing plate 608 to move completely into the inner cavity of the fixing groove 602 to avoid blocking the shooting range of the camera 4.

[0037] (2) At this time, the high-precision decorative paper roll can be placed into the inner cavity of the first positioning plate and the second positioning plate. By starting the rotating motor, the output shaft of the rotating motor rotates and drives the threaded rod 704 to rotate, thereby causing the threaded sleeve 706 connected to it to move forward. The movement of the threaded sleeve 706 can drive the linkage plate 707 and the sliding sleeve 705 to move, thereby causing the sliding sleeve 705 to slide on the outer surface of the limiting rod 703, which can limit the movement of the threaded sleeve 706, so that it can only perform linear movement. The movement of the linkage plate 707 causes the second positioning plate to move away from the first positioning plate until the first positioning plate and the second positioning plate are aligned. The distance between opposite sides of the circular grooves on the positioning plate is greater than the length of the roller in the high-precision decorative paper roll. One side of the roller is placed into the circular groove of the first positioning plate, and then the output shaft of the drive motor is reversed, which can move the second positioning plate closer to the first positioning plate until the circular groove of the second positioning plate fits over the roller. Then, one end of the high-precision decorative paper roll is pulled into the belt conveyor frame 1. At this time, the roller rotates in the circular groove and is detected by the camera 4. A winding roller is set on the right side of the belt conveyor frame 1, and one end of the detected paper roll is fixed to it, so that the detected high-precision decorative paper roll can be wound on the winding roller.
