Description

Technical Field

[0001] The present invention relates to the technical field of mark - free solar film cutting, and particularly to a mark - free solar film cutting device and method. Background Technique

[0002] Solar film (solarfilm) is also called heat - insulating film. In modern solar film production technology, metal films such as aluminum, gold, copper, and silver are often made into multi - layer dense high - heat - insulating metal film layers through vacuum spraying or magnetron sputtering technology.

[0003] The film pasted on the surface of automotive glass is commonly known as car film or explosion - proof film. Initially, it was called solar film. As the name implies, automotive film is used to deal with the hot and scorching sunlight and ultraviolet light in summer. In addition to heat insulation and light insulation, the explosion - proof film also has an explosion - proof function. High - quality explosion - proof film uses a special polyester film as the base material. The film itself has strong toughness and is combined with a special pressure - sensitive adhesive. In case of an accident, when the glass breaks, it is adhered by the car film and will not fly and hurt people. The automotive explosion - proof film also has the functions of one - way perspective and glare reduction.

[0004] When applying automotive film, first, water is sprayed on the part where the film needs to be pasted, then the template film is covered on parts such as the car window. The template film is cut according to the actual size of the car window. Then, the cut template film is placed on the solar film, the size of the template film is compared, and a certain position is reserved for cutting. Then, the cut solar film is covered on parts such as the car window for film pasting. During the film - pasting process, fine - trimming cutting is carried out according to the actual size. The time consumed for film pasting is long, and the size is not accurate enough, resulting in low film - pasting efficiency. Summary of the Invention

[0012] A method for cutting a solar film without leaving marks:

[0013] Receive the user's touch signal;

[0014] Retrieve the corresponding specific information in the database;

[0015] The corresponding specific information is the brand of the vehicle, the model of the vehicle, and a complete set of models or a model of a certain part;

[0016] Select the corresponding information;

[0017] Display the corresponding information;

[0018] Control the unfolding component to unfold and flatten the solar film;

[0019] Control the cutting component to perform cutting;

[0020] Judge whether it is necessary to cut the unfolded solar film. If cutting is required, control the separation component and the auxiliary separation component to separate the fixed plate from the solar film, then control the reset component to move the fixed plate to one side of the pressure rod, and finally control the cutting component to cut off the surplus material on one side of the fixed plate. If cutting is not required, control the first motor and the reset component to wind up the solar film;

[0021] Judge whether to continue the operation. If continuing the operation, repeat the above steps. If not continuing the operation, control the cutting component to return to the initial position.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. Through the cutting component provided in the present invention, when it is necessary to cut the solar film, first control the unfolding component to unfold the solar film, and then control the cutting, which avoids the time-consuming and inaccurate cutting during the film pasting process according to the actual size, resulting in low film pasting efficiency. It improves the cutting efficiency and accuracy of the solar film.

[0024] 2. Through the unfolding component provided in the present invention, when it is necessary to cut the solar film, the rotation of the first rotating rod can be driven by the start of the first motor. At the same time, when the fourth motor starts, the third threaded rod rotates, causing the pressure rod to move outwards, pushing the fixed plate to move outwards with the solar film, spreading the solar film on the top of the cutting table, and then cutting. When it is necessary to flatten the surface of the solar film, the fourth motor can be rotated in the reverse direction to drive the third threaded rod to rotate. Similarly, it drives the pressure rod to move towards one side of the placement box, so that the pressure rod flattens the surface of the solar film, preventing the solar film from having air pockets when spreading, affecting the cutting accuracy of the cutting part during cutting, and thus affecting the quality problem. It improves the cutting effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1

[0034] Please refer to Figures 1-3 , in the figure, a trace - free solar film cutting device and method, including a cutting table 1, a placing box 2, a solar film 3, a first rotating rod 4 and a first motor 5. A placing box 2 is provided at the top of the cutting table 1. The solar film 3 is installed inside the placing box 2. The first rotating rod 4 is embedded in the inner wall of the solar film 3. Both ends of the first rotating rod 4 pass through the inner wall of the solar film 3 and are embedded on both sides of the inner wall of the placing box 2 and are rotatably connected. One end of the first rotating rod 4 is fixedly installed with a first motor 5. A control panel 31 is installed at the top of the cutting table 1. A cutting component is provided at the top of the cutting table 1. An unfolding component is provided at the top of the solar film 3;

[0035] Among them, the cutting assembly includes a cutting part 6 arranged at the top of the cutting table 1. A first connecting block 7 is fixedly connected to the top of the cutting part 6. The first connecting block 7 is sleeved on the outer wall of the first threaded rod 8 and is threadedly connected. The first threaded rod 8 is installed in the inner wall of the connecting frame 9 and is rotationally connected. One end of the first threaded rod 8 is fixedly connected to a second motor 10. Both ends of the connecting frame 9 are sleeved on the outer wall of the second threaded rod 11 and are threadedly connected. The second threaded rod 11 is embedded in the inner walls of the two cutting tables 1 and is rotationally connected. One end of the second threaded rod 11 is fixedly connected to a third motor 12. When it is necessary to cut the solar film, first control the unfolding assembly to unfold the solar film, and then control 6 to cut. This avoids the trimming and cutting according to the actual size during the film pasting process, which takes a long time for film pasting and the size is not accurate enough, resulting in low film pasting efficiency. Thus, the cutting efficiency and accuracy of the solar film are improved.

[0036] The unfolding assembly includes a fixing plate 13 arranged at the top of the solar film 3. A separating assembly is arranged between the fixing plate 13 and the solar film 3. An auxiliary separating assembly is arranged at the top of the fixing plate 13. First sliders 14 are fixedly installed at both ends of the fixing plate 13. The first sliders 14 are sleeved on the outer wall of the third threaded rod 15 and are slidably connected. One end of the third threaded rod 15 is fixedly connected to a fourth motor 16. A pressing rod 17 is arranged on one side of the fixing plate 13. A reset assembly is arranged on the other side of the fixing plate 13. Both ends of the pressing rod 17 are sleeved on the outer wall of the third threaded rod 15 and are threadedly connected. By setting the unfolding assembly, when it is necessary to cut the solar film 3, the first motor 5 can be started to drive the rotation of the first rotating rod 4. At the same time, when the fourth motor 16 is started, it drives the third threaded rod 15 to rotate, making the pressing rod 17 move outwards, pushing the fixing plate 13 to move outwards with the solar film 3, spreading the solar film 3 on the top of the cutting table 1, and then cutting. When it is necessary to flatten the surface of the solar film 3, the fourth motor 16 can be rotated in the reverse direction to drive the third threaded rod 15 to rotate. Similarly, it drives the pressing rod 17 to move towards the side of the placement box 2, so that the pressing rod 17 flattens the surface of the solar film 3, preventing the solar film 3 from having air pockets when spreading, which affects the cutting accuracy of the cutting part 6 during cutting, thus affecting the quality problem, and improving the cutting effect.

At the same time, the first slider 14 slides on the outer wall of the third threaded rod 15, and the second slider 21 slides in the inner wall of the connecting plate 22. The movement of the fixed plate 13 drives the movement of the suction cup 19, and the movement of the suction cup 19 drives the movement of the solar film 3, pulling the solar film 3 to open at the top of the cutting table 1, and the first motor 5 stops working;

[0061] When the pressing rod 17 moves to the predetermined position, the fourth motor 16 rotates in the reverse direction, and the pressing rod 17 moves in the reverse direction to flatten the solar film 3, and the fourth motor 16 stops working;

[0062] Control the second motor 10 and the third motor 12 to start. The start of the second motor 10 drives the rotation of the first threaded rod 8.
