Description

Technical Field

[0001] This invention belongs to the field of laser cutting technology, specifically relating to a laser cutting device for the protective film of a car horn mesh. Background Technology

[0002] In the manufacturing process of new energy vehicles, the processing of protective films for irregularly shaped horn meshes still generally adopts the traditional manual cutting method. Operators need to hold knives to perform fine cutting operations. In this operating mode, operators are very likely to suffer cuts, punctures and other accidents when holding sharp knives directly. Especially when processing high-strength composite materials, the slippage of the knife or the displacement of the material may lead to more serious injuries.

[0003] Meanwhile, this processing method is labor-intensive and inefficient. Operators need to maintain bent-over and straight-over postures for extended periods to perform delicate operations, leading to significant physical exertion and fatigue. More importantly, when dealing with complex and irregularly shaped structures, the complete reliance on manual operation makes it difficult to precisely control the cutting trajectory of each product, frequently resulting in dimensional deviations and uneven cuts, affecting the consistency of the product's appearance and making it difficult to fully meet industry standards.

[0021] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0022] like Figures 1-3 As shown, a laser cutting device for a protective film on a horn mesh of an energy vehicle according to an embodiment of the present invention includes a body 1, a laser cutting component, a conveying mechanism for conveying the horn mesh, and a film coating mechanism for coating the protective film onto the surface of the horn mesh.

[0023] like Figures 1-2As shown, the machine body 1 adopts a vertical box structure. A laser cutting chamber 101 is set in the middle of the machine body 1. The laser cutting chamber 101 is a cavity structure that runs from front to back, providing working space for laser cutting. A light shield 102 is set at the opening of the laser cutting chamber 101 to prevent laser leakage and ensure operational safety. A second storage compartment 104 is set above the laser cutting chamber 101 on the machine body 1. The bottom of the second storage compartment 104 is connected to the top of the laser cutting chamber 101. The laser cutting component is installed in the second storage compartment 104, and the emitting end of the laser cutting component faces the inner cavity of the laser cutting chamber 101, which can cut the protective film of the speaker mesh that passes through the laser cutting chamber 101.

[0024] Specifically, such as Figure 5 As shown, the laser cutting assembly includes a laser module 19 and a camera 20. The laser module 19 is connected to the camera 20 by a signal. The camera 20 is used to collect and locate the position of the speaker mesh, identify the outline of the speaker mesh, obtain the position information of the workpiece, and transmit it to the control system. The laser module 19 is used to automatically match the cutting trajectory according to the positioning signal of the camera 20, execute the laser cutting action, and complete the irregular contour cutting of the protective film.

[0025] In this embodiment, the camera 20 is an industrial vision camera with high positioning accuracy, which is suitable for continuous operation requirements in industrial scenarios; the laser module 19 uses a 250W carbon dioxide radio frequency laser, which can cut a smooth kerf and cut at a speed of more than 1000mm per second. It can cover more than 1000 standard-sized speaker meshes per hour.

[0026] like Figures 5-6 As shown, further, in order to adapt to speaker mesh workpieces of different thicknesses and adjust the focal length of the laser module 19, a third storage compartment 105 communicating with the second storage compartment 104 is provided on the back of the machine body 1. A second mounting plate 21 is vertically slidably connected in the third storage compartment 105. The laser module 19 and the camera 20 are both fixedly mounted on the front of the second mounting plate 21 by bolts and move vertically synchronously with the second mounting plate 21.

[0027] Specifically, a second slider 2101 is fixedly connected to the surface of the second mounting plate 21 opposite to the inner wall of the third storage compartment 105. A slide rail 22, which slides and engages with the second slider 2101, is fixedly connected to the inner wall of the third storage compartment 105. The slide rail 22 is arranged vertically. Through the cooperation between the second slider 2101 and the slide rail 22, the second mounting plate 21 can slide smoothly vertically. A lifting adjustment handle 25 is installed on the bottom wall of the third storage compartment 105. A rotating seat 23 is fixedly installed on the lower end surface of the second mounting plate 21. A second screw 24 is installed between the rotating seat 23 and the lifting adjustment handle 25. The second screw 24 is arranged vertically. The lower end of the second screw 24 is fixedly connected to the lifting adjustment handle 25, and the upper end is rotatably connected to the rotating seat 23. The second screw 24 is threadedly connected to the bottom wall of the third storage compartment 105. In use, rotating the lifting adjustment handle 25 will drive the second screw 24 to rotate. The screw 24 will be raised and lowered vertically through the threaded engagement. Then, the rotating seat 23 will drive the second mounting plate 21 to move vertically along the slide rail 22, thereby adjusting the height of the laser module 19 and the camera 20 to adapt to workpieces of different thicknesses and ensure accurate cutting focus.

[0028] like Figures 1-2 As shown, the conveying path of the conveying mechanism runs through the laser cutting chamber 101, so that the coated speaker mesh is conveyed through the laser cutting chamber 101 by the conveying mechanism to achieve continuous conveying of the workpiece. Specifically, the conveying mechanism includes a first conveying mechanism 2 and a second conveying mechanism 3. The first conveying mechanism 2 is located at the feeding front end of the laser cutting chamber 101 and is used to convey the speaker mesh to be processed to the coating station and the laser cutting chamber 101. The conveying section of the second conveying mechanism 3 is superimposed on the cavity of the laser cutting chamber 101 and is used to receive the coated speaker mesh, convey it to the laser cutting station to complete the cutting, and send the cut speaker mesh out of the laser cutting chamber 101.

[0029] In this embodiment, the first conveying mechanism 2 adopts a belt conveying mechanism, and the second conveying mechanism 3 adopts a metal mesh conveying mechanism. The metal mesh conveying mechanism can filter the impurities generated during the laser cutting process. At the same time, the metal mesh can adapt to the high temperature during the laser module 19 cutting process, thereby extending the service life of the equipment while saving costs.

[0030] like Figures 1-3As shown, to ensure the horn mesh does not shift during transport and to guarantee positioning and cutting accuracy, a positioning guide mechanism 5 matching the second conveying mechanism 3 is installed on the machine body 1. The positioning guide mechanism 5 includes a pair of mounting seats 6, which are bolted to both sides of the frame of the second conveying mechanism 3. A vertical connecting rod 7 is fixedly connected to the mounting seat 6 in the vertical direction, and a slide block 8 is slidably connected to the vertical connecting rod 7. The slide block 8 can slide up and down along the vertical connecting rod 7 and can be fixed in position by locking bolts. A horizontal connecting rod 9 is slidably connected to the slide block 8. The horizontal connecting rod 9 and the vertical connecting rod 7 are perpendicular to each other. The horizontal connecting rod 9 can slide left and right along the slide block 8 and can be fixed in position by locking bolts, adapting to workpieces of different widths. A positioning baffle 10 is fixedly connected to one end of the horizontal connecting rod 9 near the second conveying mechanism 3. The two positioning baffles 10 are arranged opposite each other, forming a transport channel for the horn mesh. This channel guides and limits the horn mesh on both sides during transport, ensuring that the workpiece is transported along a preset path without shifting.

[0031] like Figures 1-4 As shown, the coating mechanism is located on the feeding side of the laser cutting chamber 101. It is used to coat the surface of the speaker mesh with a protective film before the speaker mesh enters the laser cutting chamber 101, thereby achieving automatic coating before cutting. Specifically, a first storage compartment 103 is provided at the lower end of the machine body 1. The coating mechanism includes a feeding shaft 11 rotatably connected to the first storage compartment 103. The feeding shaft 11 is arranged in a horizontal direction and is used to mount the protective film roll. It can rotate synchronously with the feeding of the protective film. A first gap 4 is formed between the first conveying mechanism 2 and the second conveying mechanism 3. The free end of the protective film roll extends upward from the first gap 4 and is laid on the conveying surface of the conveying mechanism. When the speaker mesh is conveyed by the first conveying mechanism 2, the protective film is synchronously coated on the surface of the speaker mesh.

[0032] like Figure 3 As shown, to ensure a smooth, bubble-free, and wrinkle-free coating, the coating mechanism also includes a coating pressing assembly 12. The coating pressing assembly 12 is installed between the first conveying mechanism 2 and the second conveying mechanism 3, located on the discharge side of the first gap 4. The coating pressing assembly 12 includes a pair of first mounting plates 13, which are respectively fixed to both sides of the conveying mechanism frame and located at the left and right ends of the conveying path. A first pressure roller 1302 is rotatably connected between the lower parts of the pair of first mounting plates 13. A vertically extending groove 1301 is provided above the first mounting plates 13. A first slider 14 matching the groove 1301 is slidably connected in the groove 1301. A second pressure roller 15 is rotatably connected between the pair of first sliders 14. The second pressure roller 15 and the first pressure roller 1302 are arranged vertically opposite each other to form a pressing gap for the speaker mesh and protective film to pass through.

[0033] A top plate 16 corresponding to the slide groove 1301 is fixedly connected to the top of the first mounting plate 13. An internally threaded sleeve 17 is fixedly connected to the top plate 16, and a first screw 18 is internally threaded onto the sleeve 17. The first screw 18 is arranged vertically, and its lower end is rotatably connected to the first slider 14. An adjusting handwheel is provided on the top of the first screw 18. In use, rotating the first screw 18 will drive the first slider 14 to slide vertically along the slide groove 1301, thereby adjusting the pressing gap between the second pressure roller 15 and the first pressure roller 1302 to accommodate different thicknesses of speaker grilles and protective films, ensuring tight, flat, and bubble-free film bonding.

[0034] In the initial state, the free end of the protective film enters between the second pressure roller 15 and the first pressure roller 1302 through the first gap 4. The second pressure roller 15 and the first pressure roller 1302 press the free end of the protective film tightly, preventing it from sliding between them. When the speaker grille passes between the second pressure roller 15 and the first pressure roller 1302, the protective film and the speaker grille are interference-fitted, and as the second pressure roller 15 and the first pressure roller 1302 rotate, the protective film is forced to gradually unfold, achieving continuous production. It is worth noting that the second pressure roller 15 and the first pressure roller 1302 are driven to rotate by two motors respectively.

[0035] like Figure 1 As shown, the laser cutting device for the protective film of the horn mesh of new energy vehicles also includes a feeding mechanism 27, which is located at the feeding end of the second conveying mechanism 3. The feeding mechanism 27 includes a third conveying mechanism 29, the feeding end of which is connected to the feeding end of the second conveying mechanism 3. A feeding housing 28 is fixedly connected to the frame of the third conveying mechanism 29. The feeding housing 28 has a feeding groove 2801 that matches the shape of the horn mesh. The feeding groove 2801 extends vertically through the feeding housing 28. A limiting gap matching the horn mesh is formed between the lower end face of the feeding housing 28 and the conveying surface of the third conveying mechanism 29. The horn mesh is conveyed to the first conveying mechanism 2 via the third conveying mechanism 29. That is, the operator can stack the horn mesh to be processed in the feeding groove 2801. The bottom workpiece falls into the limiting gap and is synchronously conveyed to the feeding end with the third conveying mechanism 29, realizing continuous feeding of workpieces and further improving work efficiency.

[0036] like Figure 6As shown, in order to ensure the stability of the laser module 19 during long-term continuous operation, the laser cutting device for the protective film of the electric vehicle horn mesh also includes a circulating water chiller 26. The circulating water chiller 26 is installed on the side of the machine body 1. A water cooling pipe 2601 is installed between the circulating water chiller 26 and the laser module 19. The circulating water chiller 26 provides circulating water cooling for the laser module 19 through the water cooling pipe 2601, which avoids the laser module 19 from overheating during long-term operation, ensures stable cutting power, and extends the service life of the equipment.

[0037] The working process of the laser cutting device for the protective film of the new energy vehicle speaker grille in this embodiment is as follows: The protective film roll is placed on the feeding shaft 11, and the free end of the protective film is pulled out from the first gap 4, passing through the pressing gap between the first pressure roller 1302 and the second pressure roller 15, and laid on the conveying surface of the conveying mechanism. According to the thickness and width of the speaker mesh to be processed, the horizontal position and vertical height of the positioning baffle 10 are adjusted, the size of the pressing gap is adjusted, and the focal length of the laser module 19 is adjusted to complete the equipment debugging.

[0038] The speaker mesh to be processed is placed on the first conveying mechanism 2, which conveys the speaker mesh forward. When the speaker mesh passes the film pressing assembly 12, the protective film is simultaneously applied to the surface of the speaker mesh and pressed flat by the first pressure roller 1302 and the second pressure roller 15 to complete the film pressing operation.

[0039] After being coated, the speaker mesh is conveyed into the laser cutting chamber 101 by the second conveying mechanism 3. The camera 20 collects the image information of the speaker mesh, accurately locates the position and outline of the workpiece, and transmits the positioning signal to the control system. The control system controls the laser module 19 to perform laser cutting action according to the preset trajectory, completes the precise cutting of the speaker mesh protective film, and the cut speaker mesh is sent out of the laser cutting chamber 101 by the second conveying mechanism 3, realizing fully automated operation.

[0040] Through the above-described working process, the laser cutting device for the protective film of the new energy vehicle speaker grille provided in this embodiment has at least the following beneficial effects: The use of laser module 19 for non-contact cutting replaces the traditional manual operation with sharp blades, eliminating the risk of cuts and punctures and significantly improving operational safety. Simultaneously, the enclosed cutting space formed by the laser cutting chamber 101 and the light-blocking plate 102 effectively prevents laser leakage, further ensuring a safe and reliable production environment. The positioning and guiding mechanism 5 provides double-sided limiting and guiding for the speaker mesh during the conveying process, preventing workpiece deviation and achieving primary physical positioning. Then, the industrial-grade camera 20 performs visual acquisition and precise alignment of the speaker mesh's contour and positioning features, achieving secondary visual positioning. With dual positioning, the cutting accuracy is greatly improved, making it suitable for cutting the complex contours of various irregular curved speaker meshes for new energy vehicles.

[0041] The second mounting plate 21 can be driven to move vertically by adjusting the lifting handle 25 in conjunction with the second screw 24, thereby adjusting the cutting focal length of the laser module 19 and adapting to different specifications of speaker mesh workpieces with thicknesses ranging from 0.5mm to 10mm. The distance and height of the two positioning baffles 10 can be flexibly adjusted by sliding the slide block 8 and the transverse connecting rod 9, adapting to the conveying and guiding of workpieces of different widths. The pressing gap between the second pressure roller 15 and the first pressure roller 1302 can be adjusted by the first screw 18, adapting to speaker meshes of different thicknesses and protective films of different materials, ensuring that the film coating is flat and free of bubbles. The processing of multiple types of workpieces can be completed without changing the main body of the equipment, which greatly reduces the investment cost of production equipment.
