However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a protective film application device for carbon fiber sheet surface, including a support frame 1, a placement plate 15 is provided at the upper end of the support frame 1, a control panel 16 is installed on one side of the support frame 1, a tension adjustment mechanism 2 is provided at the upper end of the support frame 1, and a pulling mechanism 3 is provided at one end of the support frame 1.

[0024] The tension adjustment mechanism 2 includes a concave seat 21. Two sets of movable plates 22 are slidably mounted through the upper end of the support frame 1. A cooperating roller 23 is rotatably mounted in the middle of the two sets of movable plates 22. A first telescopic rod 24 is mounted at the lower end of the concave seat 21. A connecting plate 26 is mounted at the lower end of the two sets of movable plates 22. A displacement sensor 27 is mounted at the upper end of one set of movable plates 22. Two sets of guide rods 25 are slidably mounted through the lower end of the concave seat 21. The upper end of the concave seat 21 is fixed to the inner top of the support frame 1. The protruding end of the first telescopic rod 24 passes through the lower end of the concave seat 21 and is fixed to the lower end of the connecting plate 26. The upper ends of the two sets of guide rods 25 are both fixed to the lower end of the connecting plate 26. The first telescopic rod 24 and the displacement sensor 27 are both signal connected to the control panel 16.

[0025] A feeding mechanism 11 is installed at the upper end of the support frame 1, a support frame 12 is installed at the upper end of the support frame 1, a cutting mechanism 13 is installed on the inner wall of the support frame 12, and a pressing mechanism 14 is installed at the upper end of the support frame 12.

[0026] The specific setup and function of this embodiment are described below. The support frame 1 is the basic frame, integrating the placement plate 15, control panel 16, tension adjustment mechanism 2, pulling mechanism 3, feeding mechanism 11, support frame 12, cutting mechanism 13, and pressing mechanism 14, forming a complete carbon fiber sheet surface protective film application system. Each mechanism achieves fully automated operation of the carbon fiber sheet from feeding to film application through a combination of mechanical connections and electrical control.

[0027] The support frame 1 serves as the foundation for the entire device. It is made of high-strength alloy material and has sufficient structural rigidity to stably support the operation of various functional mechanisms. At the same time, it provides installation space for internal wiring and mechanical transmission components. The placement plate 15 is located at the top of the support frame 1. Its surface is smoothed and it is used to support the carbon fiber sheet to be coated. Its size can be designed according to common sheet specifications to ensure that the sheet is placed stably.

[0028] The control panel 16 is installed on one side of the support frame 1 and integrates a display screen, operation buttons and control chip. As the core of human-machine interaction, it can receive signals from various sensors and send control commands to the execution components to realize the setting of device operating parameters, status monitoring and fault alarm.

[0029] The core components of the tension adjustment mechanism 2 consist of a concave seat 21, two sets of movable plates 22, a cooperating roller 23, a first telescopic rod 24, a connecting plate 26, a displacement sensor 27, and two sets of guide rods 25.

[0030] Structural relationship: The upper end of the concave seat 21 is fixedly connected to the inner top of the support frame 1, and the lower end is slidably installed with two sets of guide rods 25. The upper end of the guide rods 25 is fixed to the lower end of the connecting plate 26. The first telescopic rod 24 is installed at the lower end of the concave seat 21, and its protruding end passes through the concave seat 21 and is fixed to the lower end of the connecting plate 26, providing power for the lifting and lowering of the movable plate 22. The two sets of movable plates 22 are slidably installed at the upper end of the support frame 1, with a mating roller 23 rotatably installed in the middle, and the lower end is fixed to the connecting plate 26. The displacement sensor 27 is installed at the upper end of one set of movable plates 22 to detect the displacement change of the movable plate 22.

[0031] When the protective film passes the mating roller 23, the displacement sensor 27 detects the position change of the movable plate 22 in real time, indirectly reflecting the tension state of the film, and transmits the signal to the control panel 16. The control panel 16 controls the extension and retraction of the first telescopic rod 24 according to the preset tension parameters, and drives the movable plate 22 and the mating roller 23 to move up and down through the connecting plate 26, adjusting the pressure of the mating roller 23 on the film, thereby precisely adjusting the film tension. The guide rod 25 plays a guiding role during the lifting and lowering of the movable plate 22 to prevent it from deviating and ensure the stability of the tension adjustment.

[0032] The feeding mechanism 11 is installed at the upper end of the support frame 1, located on the feeding side of the placement plate 15. It can adopt a structure of conveyor belt and guide plate. Its function is to smoothly transport the carbon fiber sheet to be processed onto the placement plate 15. The guide plate can be adjusted according to the width of the sheet to ensure that the sheet accurately enters the subsequent processing station.

[0033] The support frame 12 is installed at the upper end of the support frame 1, spanning across the plate conveying path, and provides installation support for the cutting mechanism 13 and the pressing mechanism 14. Its height can be designed according to the plate thickness and the operating requirements of the mechanism.

[0034] The cutting mechanism 13 is installed on the inner wall of the support frame 12 and located on the discharge side of the pressing mechanism 14. It can adopt a structure of pneumatically driven cutting blade and positioning sensor. When the board with film applied is transported to the cutting position, the positioning sensor detects the edge of the board and the control panel 16 controls the cutting blade to cut off the excess film according to the set size, so as to ensure that the edge of the film is neat.

[0035] The pressing mechanism 14 is installed on the upper end of the support frame 12, corresponding to the position above the placement plate 15. It can adopt a symmetrically arranged pressure roller group. The upper pressure roller is connected to the pressure adjustment component. When the plate covered with protective film passes through the pressing mechanism 14, the pressure roller group applies uniform pressure to it, so that the film is tightly attached to the surface of the plate and air bubbles are eliminated. The pressure adjustment component can adjust the pressure according to the thickness of the plate and the characteristics of the film.

[0036] Example 2: Figure 1 , Figure 2 and Figure 4 As shown, the pulling mechanism 3 includes a concave plate 31, a support plate 32 is installed at one end of the support frame 1, a diagonal brace frame 33 is installed at the lower end of the support plate 32, a second telescopic rod 34 is installed on the inner wall of the diagonal brace frame 33, a baffle 35 is installed at one end of the support plate 32, and a concave rod 36 is slidably installed through one end of the baffle 35. The lower end of the concave plate 31 is fixed to the upper end of the support frame 1, the other end of the diagonal brace frame 33 is fixed to one end of the support frame 1, one end of the concave rod 36 is fixed to one end of the placement plate 15, and the other end of the concave rod 36 is fixed to the extended end of the second telescopic rod 34. The second telescopic rod 34 is connected to the control panel 16 via a signal.

[0037] The overall effect achieved by the embodiment is that the core components of the pulling mechanism 3 include a concave plate 31, a support plate 32, a diagonal brace frame 33, a second telescopic rod 34, a baffle 35, and a concave rod 36.

[0038] Structural relationship: The lower end of the concave plate 31 is fixed to the upper end of the support frame 1 to limit the conveying path of the plate; the support plate 32 is installed at one end of the support frame 1, and its lower end is connected to the inclined support frame 33. The other end of the inclined support frame 33 is fixed to one end of the support frame 1 to form a triangular support structure, which enhances the load-bearing capacity of the support plate 32; the second telescopic rod 34 is installed on the inner wall of the inclined support frame 33, the baffle 35 is installed at one end of the support plate 32, and the concave rod 36 is slidably installed through one end of the baffle 35. One end of the rod is fixed to one end of the placement plate 15, and the other end is fixed to the extended end of the second telescopic rod 34.

[0039] After the carbon fiber sheet is placed on the placement plate 15, the control panel 16 controls the extension and retraction of the second telescopic rod 34, which drives the placement plate 15 to move horizontally through the concave rod 36, thereby realizing the conveying of the sheet. The baffle 35 guides and limits the movement of the concave rod 36 to prevent it from deviating. The concave plate 31 constrains both sides of the sheet during the conveying process to ensure the accuracy of the conveying direction.

[0040] The operation and working principle of this device are as follows: After the device is started, the operator first sets various operating parameters through the control panel 16 on one side of the support frame 1, including film tension value, pressing pressure, conveying speed and cutting size. After the parameters are set, the feeding mechanism 11 starts to work and smoothly conveys the carbon fiber sheet to be filmed onto the placement plate 15. At the same time, the concave plates 31 on both sides limit the sheet to prevent deviation during the conveying process.

[0041] Once the board is fully inserted into the placement plate 15, the control panel 16 sends a command to the second telescopic rod 34 of the pulling mechanism 3 to control its extension. The second telescopic rod 34 is installed on the inner wall of the inclined support frame 33. Its extended end drives the placement plate 15 to move horizontally through the concave rod 36 to realize the conveying of the board. During this process, the baffle 35 guides the movement of the concave rod 36 to prevent it from deviating and ensure that the board moves accurately to the subsequent work station.

[0042] When the sheet material is conveyed to the tension adjustment mechanism 2, the protective film is drawn out from the unwinding device and passes through the mating roller 23. At this time, the tension adjustment mechanism 2 starts to work: the displacement sensor 27 installed on the upper end of the movable plate 22 detects the position change of the movable plate 22 in real time, indirectly reflecting the tension state of the film, and transmits the signal to the control panel 16. The control panel 16 compares the real-time detection value with the preset tension parameters. If there is a deviation, it controls the extension and retraction of the first telescopic rod 24. The extended end of the first telescopic rod 24 drives the two sets of movable plates 22 to move up and down through the connecting plate 26, thereby causing the mating roller 23 in the middle of the movable plate 22 to move up and down, adjusting the pressure of the mating roller 23 on the film, and realizing the precise adjustment of the film tension. At the same time, the two sets of guide rods 25 play a guiding role during the lifting and lowering of the movable plate 22 to prevent the movable plate 22 from deviating and ensure the stability of the tension adjustment.

[0043] As the pulling mechanism 3 continues to move the board, the board enters the working area of ​​the pressing mechanism 14. The pressing mechanism 14 is installed on the upper end of the support frame 12, corresponding to the position above the board 15. When the board covered with protective film passes through the pressure roller group, the pressure roller group applies uniform pressure to it, so that the film is tightly attached to the surface of the board and air bubbles are eliminated. The pressure adjustment component can automatically adjust the pressure according to the thickness of the board and the characteristics of the film to ensure the pressing effect.

[0044] After pressing, the board is conveyed to the working position of the cutting mechanism 13. The cutting mechanism 13 is installed on the inner wall of the support frame 12 and located on the discharge side of the pressing mechanism 14. It uses a pneumatically driven cutting knife in conjunction with a positioning sensor. When the positioning sensor detects that the edge of the board has reached the set cutting position, it sends a signal to the control panel 16. The control panel 16 controls the cutting knife to cut off the excess film according to the set size, ensuring that the edge of the film is neat.

[0045] After cutting, the pulling mechanism 3 continues to move the film-coated board until it is conveyed to the discharge area of ​​the device, completing the entire film-coating operation. Throughout the entire process, the control panel 16 continuously monitors the operating status of each mechanism. If any abnormality occurs, a fault alarm will be issued in a timely manner to ensure the safe and stable operation of the device.

[0046] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
