Description

Technical Field

[0001] This invention belongs to the field of laser cutting technology, specifically relating to a laser cutting device and method for sound insulation carpets used in electric vehicles. Background Technology

[0002] Car soundproofing carpets are an important interior component of automobiles. They not only enhance the comfort and aesthetics of the vehicle but also effectively reduce interior noise, providing a quieter driving and riding environment for the driver and passengers. Car soundproofing carpets typically employ a multi-layered composite structure, including sound-absorbing layers and sound-insulating layers. The sound-absorbing layer absorbs reflected sound waves inside the car, reducing noise reverberation; the sound-insulating layer effectively blocks external noise from entering the vehicle.

[0003] Car soundproof carpets require laser cutting during processing. Existing laser cutting equipment for soundproof carpets is prone to cutting errors due to the unevenness of the carpet surface. Furthermore, the heat generated during cutting can damage the internal structure of the soundproof carpet, thereby reducing its soundproofing effect.

[0019] This invention also relates to a method for cutting sound-insulating carpets for electric vehicles, using the aforementioned laser cutting device for sound-insulating carpets for electric vehicles, comprising the following steps:

[0020] (1) Before use, the pressure roller is in the raised state, and the distance between the rotating roller and the pressure roller is the largest; the clamping assembly is in the leftmost position closest to the film pressing mechanism, and the clamping plate is in the raised state; the laser emitter is in the raised state and is located at the front or the back; the winding assembly is located at the rightmost position and is in the raised state.

[0021] (2) Pressing the film: Place the carpet between the rotating roller and the pressure roller. The lifting component 2 drives the pressure roller to press the film onto the carpet. The pressure roller rotates and moves the carpet and film to the clamping component. The pressure roller rises through the lifting component 2 until the film is only pressed against the carpet surface without squeezing the carpet and causing deformation. The clamping component moves the carpet and film to the right through the moving component 1. The carpet and film are spread on the vacuum plate.

[0022] (3) Cutting: The moving component three drives the lifting component one to move to the carpet cutting position. The lifting component one drives the laser emitter to the optimal cutting height. At the same time, the vacuuming mechanism is started. The laser emitter moves from the front side to the back side, or from the back side to the front and back sides to complete the cutting of the carpet. Then the lifting component one drives the laser emitter to rise to the highest state.

[0023] (4) Removing the film: The second moving component drives the winding component to move to the right to the edge of the carpet cutting point. After the winding component collects the film, it moves to the top of the waste film tank through the second moving component. The film cutting component cuts the wound film, and the cut film falls into the waste film tank.

[0024] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0025] (1) The laser cutting device for the sound insulation carpet for electric vehicles covers a protective film on the surface of the carpet before laser cutting. The film is in a tensile state due to the tension of the clamping components and the pressure roller, which can prevent uneven carpet surface from causing cutting errors.

[0026] (2) After the clamping assembly clamps the carpet and the film, the laser cutting device for the sound insulation carpet of the electric vehicle adjusts the pressure roller to rise so that the film only adheres to the surface of the carpet without squeezing the carpet and causing deformation, so that the internal structure of the sound insulation carpet is not damaged, thereby ensuring the sound insulation effect of the carpet.

[0027] (3) The laser cutting device for the sound insulation carpet for electric vehicles can cut the film by the film cutting assembly after the cut film is wrapped around the cylinder, and then drop it into the waste film tank, so as to remove the film after the next batch of carpet is cut.

[0028] (4) When the laser cutting device of the sound insulation carpet for electric vehicles is cutting, the dust in the dust inlet enters with the airflow and accumulates on the dust plate. At the same time, the dust inlet drives the airflow through the carpet cutting area, which can eliminate the heat generated by cutting and avoid the impact on the carpet structure, thereby preventing the impact on the sound insulation effect.

[0029] (5) After the dust collection plate is removed, the dust collection plate of the laser cutting device for the sound insulation carpet of the electric vehicle can be removed to clean the debris on it, so as to prevent a large amount of debris from accumulating and reducing the air flow rate, thereby reducing the dust collection effect and heat dissipation effect.

[0064] Example 2

[0065] A method for cutting sound-insulating carpets for electric vehicles, using Figures 1-14 The laser cutting apparatus for sound insulation carpets for electric vehicles shown includes the following steps:

[0066] (1) Before use, the pressure roller 69 is in the raised state, the distance between the rotating roller 68 and the pressure roller 69 is the largest; the clamping assembly is in the leftmost position closest to the film pressing mechanism, the clamping plate 11 is in the raised state; the laser emitter 60 is in the raised state and is located at the front or the back; the winding assembly is located at the rightmost position and is in the raised state.

[0067] (2) Film pressing: Place the carpet between the rotating roller 68 and the pressure roller 69, start the motor 82, and drive the bevel gear 81, bevel gear 80, transmission rod 79 and lifting plate 78 to rotate in sequence. The rectangular frame 77 drives the lifting plate 74 to move downward, thereby moving the pressure roller 69 downward. The rotating roller 68 and the pressure roller 69 squeeze the carpet. The pressure on the film roll 72 is transmitted to the pressure sensing structure 71, and the pressure sensing structure 71 then transmits the pressure to the pressure sensor 70 until the pressure sensor 70 senses the pressure to the set value. At this time, the film is tightly attached to the carpet, and the carpet is squeezed and deformed. Start the motor 75, and the pressure roller 69 rotates. The rotating roller 68 is subjected to pressure and the pressure roller 69 rotates. The machine rotates, causing the carpet and film to move simultaneously to the right between clamping plates 11 and 12. At the same time, the two linear telescopic devices 10 are activated, and clamping plate 11 moves downward to clamp the carpet and film. The motor 982 is activated again, causing the pressure roller 69 to move upward. The deformation of the carpet caused by the compression gradually recovers until the carpet is no longer compressed and the film adheres to the carpet surface. Then, the motor 21 is activated, which drives bevel gear 20, bevel gear 19 and lead screw 16 to rotate in sequence. Slider 28 moves to the right on lead screw 16. Rectangular block 8 drives clamping plates 11 and 12 to move to the right, thereby moving the ends of the carpet and film to the right. The carpet and film are spread on the vacuum plate 5.

[0068] (3) Cutting: Start motor 50, which drives the two lead screws 49 to rotate, and the two sliding plates 52 drive the lifting assembly 1 to move to the carpet cutting position; start motor 7 64, which drives the transmission rod 1 65, the two bevel gears 67, the two gear plates 61, and the two rotating rods 53 to rotate in sequence, so that the U-shaped frame 55 moves downward until the laser emitter 60 reaches the optimal cutting height; start motor 6 58, which drives the lead screw 57 to rotate and drive the slider 4 59 to move, so that the laser emitter 60 moves from the front side to the back side, or from the back side to the front and back sides, to complete the cutting of the carpet; start motor 7 64 again, and the laser emitter 60 rises to the highest state; when cutting the carpet, start the dust suction mechanism. When cutting, the debris enters from the dust inlet 6 with the airflow and gathers above the dust collection plate 4. At the same time, the dust suction mechanism drives the airflow through the carpet cutting area, which can eliminate the heat generated by cutting.

[0069] (4) Film Removal: Start motor 2 30, which simultaneously drives lead screw 2 26 and lead screw 3 27 to rotate. The two sliders 3 31 drive the winding assembly to move to the right to the edge of the carpet cutting area. Start the two linear telescopic devices 2 22. The cylinder 32 moves down so that the rubber suction cup 34 fits tightly with the film and squeezes out the air between the rubber suction cup 34 and the film. The rubber suction cup 34 sucks up the film. Start motor 3 40, which drives the large gear to rotate. The large gear meshes with the three external gears 37, thereby causing the internal gear 3 6. Rotate the cylinder 32 to wind the film onto the cylinder 32. Start the second motor 30 again to move the cylinder 32 above the waste film tank 33. Start the fourth motor 43 to drive the second rotating rod 42 and the circular turntable 41 to rotate in sequence. As a result, the cylindrical limiting structure 45 makes a circular motion around the center of the circular turntable 41. Due to the limitation of the cylinder, the lifting rod 46 can only move up and down. The lifting rod 46 drives the film cutting knife 47 to move upward to cut the film wrapped around the cylinder. The cut film falls into the waste film tank 33.
