Description

Technical Field

[0001] This invention belongs to the technical field of laser cutting, specifically relating to a laser cutting forming equipment for automotive trim parts. Background Technology

[0002] In the automobile production process, including the production of automotive trim parts, common trim parts include seat covers, ambient lighting, and various in-vehicle parts. When producing automotive seat covers, especially suede inner covers, laser cutting machines are used to scribing the suede in order to create clear outlines and enhance the refinement and design of the interior.

[0003] When using a laser cutting machine to scribble lines on suede, fumes are generated. To avoid environmental pollution and protect workers' health, the fumes are absorbed and treated. A common method is to install a strip exhaust fan at the front or one end of the processing bed to treat the fumes. This method can absorb fumes when processing suede close to the strip exhaust fan. However, suede is generally quite long (sitting chairs are not short to begin with, and the suede in this case is even longer when laid out). When processing suede farther away from the strip exhaust fan, the suction power of the strip exhaust fan weakens due to the distance, making it difficult to guarantee the effectiveness of fume treatment. Summary of the Invention

[0004] The purpose of this invention is to provide a laser cutting and forming equipment for automotive trim parts, which aims to solve the problems mentioned in the background art.

The fixing ring has six strip-shaped openings, and a T-shaped block fixed to the cylinder slides in each of the six strip-shaped openings. The T-shaped block cooperates with the protective plate.

[0009] As a preferred embodiment of the laser cutting and forming equipment for automotive trim parts of the present invention, the six protective plates are combined to form an outer ring with a diameter larger than that of the laser cutting head, and the distance between the arc-shaped opening and the laser cutting head increases sequentially in the counterclockwise direction along the rotating ring.

[0010] As a preferred embodiment of the laser cutting and forming equipment for automotive trim parts of the present invention, the filling mechanism includes a guide rod fixedly connected to the replacement plate, an arc-shaped groove that cooperates with the guide rod on the fixing ring, a T-shaped anti-detachment groove on the inner wall of the opening groove, and a T-shaped anti-detachment strip fixedly connected to the replacement plate.

[0011] As a preferred embodiment of the laser cutting and forming equipment for automotive trim parts of the present invention, the secondary filling mechanism includes a support groove disposed on a replacement plate, a rotating shaft rotatably connected in the support groove, a moving block fixedly connected on the rotating shaft, a first torsion spring disposed on the rotating shaft, an L-shaped mounting opening penetrating through the guide rod, the mounting opening extending into the support groove, two wedge blocks slidably connected in the mounting opening, an extension groove communicating with the mounting opening, the wedge blocks being elastically connected to the inner wall of the extension groove through the first spring, and an inclined groove cooperating with the wedge blocks being provided on the arc-shaped groove, the depth of the inclined groove decreasing sequentially along the direction away from the laser cutting head.

[0012] As a preferred embodiment of the laser cutting and forming equipment for automotive trim parts of the present invention, the unfolding mechanism includes an L-shaped opening disposed on a T-shaped block, a first slider slidably connected inside the L-shaped opening, an L-shaped limiting opening on the first slider, a drive shaft rotatably connected inside the limiting opening, a second torsion spring disposed on the drive shaft, a connecting block fixedly connected to the drive shaft and fixed to the protective plate, and a second slider cooperating with the first slider disposed inside the strip-shaped opening.

[0013] As a preferred embodiment of the laser cutting forming equipment for automotive trim parts of the present invention, both the first slider and the second slider are provided with mutually cooperating bevels, and the side wall of the connecting block near the laser cutting head abuts against the inner wall of the limiting port.

[0014] As a preferred embodiment of the laser cutting and forming equipment for automotive trim parts of the present invention, the cylinder is provided with a reset component for resetting the first slider; the reset component includes a through groove that passes through the cylinder and extends into the L-shaped opening, a movable column is slidably connected in the through groove, the lower end of the movable column is fixedly connected to the first slider, and a stop ring is fixedly connected to the upper end of the movable column, the stop ring being elastically connected to the inner wall of the through groove by a second spring.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. By setting up multiple protective plates, smoke extraction components and adjustment mechanisms, six protective plates form a sealed space on the outside of the laser cutting head to prevent smoke and dust from overflowing. The smoke extraction components are used to extract the smoke and dust. Since the protective plates and smoke extraction components move with the laser cutting head, the smoke extraction effect can be guaranteed no matter which part of the chamois is being cut.

[0018] 2. By setting up a replacement plate and a filling mechanism, the sealed space formed by the protective plate can be expanded, allowing it to hold more smoke and dust. This prevents the protective plate from forming a small sealed space when there is a lot of smoke and dust, which would cause smoke and dust to accumulate. At the same time, the filling mechanism can adjust and fill the gaps formed when the protective plate is extended outward, ensuring the sealing of the outside of the laser cutting machine.

[0019] 3. By setting a secondary filling mechanism, during the sealing process of the replacement plate, the moving block at the outer end of the replacement plate can be rotated through transmission, forming another seal at the outer end of the replacement plate, further increasing the sealing effect.

[0020] 4. By setting up an unfolding mechanism, when it is necessary to repair the lower end of the laser cutting head, the connecting block can be moved to the outside of the L-shape and deflected by continuing to rotate the rotating ring, which will cause multiple six protective plates to unfold, thus avoiding obstruction of the lower end of the laser cutting head and facilitating repair.

[0034] To make the objectives, features, and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] Example 1

[0036] Reference Figure 1 - Figure 11 This is the first embodiment of the present invention, which provides a laser cutting and forming equipment for automotive trim parts, achieving a better smoke and dust absorption effect. It includes a laser cutting head 11, a fixing ring 12 disposed on the laser cutting head 11, six protective plates 13 disposed on the lower side of the fixing ring 12 to prevent smoke and dust from escaping, a smoke extraction assembly 14 disposed on the laser cutting head 11, opening slots 15 disposed on the multiple protective plates 13, and a replacement plate 16 disposed within the opening slots 15; an adjustment mechanism disposed on the laser cutting head 11, which provides power for the movement of the protective plates 13; a filling mechanism disposed on the fixing ring 12, which provides power for the movement of the replacement plate 16, and the movement of the replacement plate 16 fills the gaps after the movement of the protective plates 13; a secondary filling mechanism disposed on the replacement plate 16, which forms a secondary seal at the connection between two adjacent replacement plates 16; and an unfolding mechanism disposed on the fixing plate, which allows the multiple protective plates 13 to be opened for maintenance of the lower end of the laser cutting head 11.

[0037] The laser cutting head 11 here includes a laser cutting head 11 housing and a laser emitting area for laser cutting. The fixing ring 12 is fixed on the laser cutting head 11 housing. When multiple protective plates 13 move outward, a gap will be formed between two adjacent protective plates 13. The replacement plate 16 is used to compensate for this gap. The rotating ring 21 here has damping and will not rotate on its own.

[0038] Furthermore, the smoking assembly 14 includes an absorption ring 141 fixedly connected to the laser cutting head 11. The absorption ring 141 has smoking ports 142 on its sidewalls and lower end face. A negative pressure tube 143 with a certain negative pressure is provided at the upper end of the absorption ring 141. The adjustment mechanism includes a rotating ring 21 rotatably connected to the laser cutting head 11. The rotating ring 21 has six arc-shaped openings 22, and cylinders 23 slide within each of the six arc-shaped openings 22. Caps 24 are fixedly connected to the cylinders 23. The fixing ring 12 has six strip-shaped openings 25. Within each of the six strip-shaped openings 25... Each of the six protective plates 13 is slidably connected to a T-shaped block 26 fixed to the cylinder 23, and the T-shaped block 26 cooperates with the protective plate 13. The six protective plates 13 are combined to form an outer ring with a diameter larger than that of the laser cutting head 11. The distance between the arc-shaped opening 22 and the laser cutting head 11 increases sequentially in the counterclockwise direction along the rotating ring 21. The filling mechanism includes a guide rod 31 fixedly connected to the replacement plate 16. The fixed ring 12 is provided with an arc-shaped groove 32 that cooperates with the guide rod 31. The inner wall of the opening groove 15 is provided with a T-shaped anti-detachment groove 33. A T-shaped anti-detachment strip 34 is fixedly connected to the replacement plate 16.

[0039] It should be noted that the smoke inlet 142 is located at the lower end and side wall of the absorption ring 141. When the protective plate 13 moves outward, the absorption ring 141 can absorb smoke and dust from the side wall and lower end, resulting in better absorption. Here, the negative pressure pipe 143 is connected to the external smoke extractor, which can generate negative pressure to absorb smoke and dust. The negative pressure here is sufficient to ensure the absorption of smoke and dust. At the same time, the negative pressure pipe 143 passes through the fixed ring 12 and extends outward between the rotating ring 21 and the fixed ring 12, so that the negative pressure pipe 143 will not bend. The width of the T-shaped block 26 is greater than the width of the strip opening 25, thereby preventing the protective plate 13 from separating from the fixed plate. The anti-detachment groove 33 and the anti-detachment strip 34 are set to prevent the protective plate 13 from separating from the replacement plate 16 and to prevent the guide rod 31 from detaching from the arc groove 32.

[0040] In use, initially, the six protective plates 13 form a closed outer ring for protection. The laser cutting head 11 performs cutting, and the resulting fumes are concentrated within the outer ring. At this time, the negative pressure pipe 143 provides negative pressure, and the fumes are absorbed by the smoke inlet 142 to prevent overflow. When the fumes are large, requiring more space or more smoke inlets 142, the rotating ring 21 is rotated clockwise. Protrusions can be provided on the side wall of the rotating ring 21 to facilitate its movement. Since the distance between the arc-shaped opening 22 and the laser cutting head 11 increases counterclockwise along the rotating ring 21, clockwise rotation of the rotating ring 21 causes the cylinder 23 to move away from the laser cutting head 11, which in turn causes the T-shaped block 26 to move away from the laser cutting head 11, and the protective plates 13 to move away from the laser cutting head 11. As the protective plate 13 moves outward, it will also drive the replacement plate 16 to move outward. When the replacement plate 16 moves, the guide rod 31 slides in the arc groove 32. Under the guidance of the arc groove 32, the guide rod 31 moves outward to move towards the adjacent protective plate 13, driving the replacement plate 16 to move away from the opening groove 15. When the protective plate 13 moves, a gap will be generated between the two adjacent protective plates 13. At this time, the replacement plate 16 moves away from the opening groove 15, and the two adjacent replacement plates 16 abut against each other, continuing to seal the outside of the laser cutting head 11 to prevent the smoke from overflowing and make the smoke extraction effect better. It is worth noting that since the absorption ring 141 is on the laser cutting head 11 and is located below the fixed ring 12, the dust is absorbed before it reaches the fixed ring 12, so there is no need to consider the sealing of the upper side of the absorption ring 141.

[0041] Example 2

[0042] Reference Figure 1 - Figure 9 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a secondary filling mechanism for the laser cutting and forming equipment for automotive trim parts, which solves the problem of how to further seal the outside of the laser cutting head 11. It includes a support groove 41 set on the replacement plate 16, a rotating shaft 42 rotatably connected in the support groove 41, a moving block 43 fixedly connected on the rotating shaft 42, a first torsion spring 44 provided on the rotating shaft 42, an L-shaped mounting port 45 extending through the guide rod 31, the mounting port 45 extending into the support groove 41, two wedge blocks 46 slidably connected in the mounting port 45, an extension groove 47 connected in the mounting port 45, the wedge blocks 46 being elastically connected to the inner wall of the extension groove 47 by the first spring 48, and an inclined groove 49 on the arc-shaped groove 32 that cooperates with the wedge blocks 46, the depth of the inclined groove 49 decreasing sequentially along the direction away from the laser cutting head 11.

[0043] Specifically, when two adjacent substitute plates 16 abut against each other, their contact surface is small. As the protective plate 13 continues to move outward, the contact surface between the two adjacent substitute plates 16 will become even smaller. In order to ensure the sealing effect, the two moving blocks 43 abut against each other to form a secondary seal. The depth of the inclined groove 49 decreases sequentially along the direction away from the laser cutting head 11, so that when the substitute plates 16 move away from the direction away from the opening groove 15, the wedge block 46 in the guide rod 31 will move downward.

[0044] In use, when the replacement plate 16 moves away from the opening slot 15, the wedge block 46 cooperates with the inclined groove 49. Since the depth of the inclined groove 49 decreases sequentially along the direction away from the laser cutting head 11, the wedge block 46 moves downward, causing another wedge block 46 to move towards the support groove 41, pushing the moving block 43 to rotate, filling the gap when the two adjacent replacement plates 16 abut against each other, and forming a seal again in the gap between the two adjacent replacement plates 16, thus improving the sealing effect and further preventing the leakage of dust and smoke. The setting of the first spring 48 and the first torsion spring 44 facilitates the reset of the wedge block 46 and the moving block 43.

[0045] Example 3

[0046] Reference Figure 1 - Figure 11 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an unfolding mechanism for a laser cutting and forming equipment for automotive trim parts. It solves the problem of how to unfold the protective plate 13 to facilitate the maintenance or disassembly of the laser emission port of the laser cutting head 11. It includes an L-shaped opening 51 set on the T-shaped block 26. A first slider 52 is slidably connected in the L-shaped opening 51. The first slider 52 is provided with an L-shaped limiting opening 53. A drive shaft 54 ​​is rotatably connected in the limiting opening 53. A second torsion spring is provided in the drive shaft 54. A connecting block 55 fixedly connected to the drive shaft 54 ​​and fixed to the protective plate 13 is fixedly connected in the drive shaft 54. A second slider 56 that cooperates with the first slider 52 is provided in the strip-shaped opening 25. Both the first slider 52 and the second slider 56 are provided with mutually cooperating inclined edges 57. The side wall of the connecting block 55 near the laser cutting head 11 abuts against the inner wall of the limiting opening 53.

[0047] Specifically, the second slider 56 pushes the first slider 52 downward a sufficient distance to ensure that there is enough room for rotation when the protective plate 13 rotates, thus avoiding jamming between the protective plate 13 and the fixed plate. Here, the side wall of the connecting block 55 near the laser cutting head 11 abuts against the inner wall of the limiting port 53 to prevent the protective plate 13 from deflecting towards the laser cutting head 11. When the connecting block 55 is inside the L-shaped port 51, the connecting block 55 abuts against the inner wall of the L-shaped port 51, preventing the connecting block 55 from deflecting. At this time, the second torsion spring is in a compressed state.

[0048] Furthermore, the cylinder 23 is provided with a reset member 58 for resetting the first slider 52; the reset member 58 includes a through groove 581 that passes through the cylinder 23 and extends into the L-shaped opening 51, a movable column 582 is slidably connected in the through groove 581, the lower end of the movable column 582 is fixedly connected to the first slider 52, and a stop ring 583 is fixedly connected to the upper end of the movable column 582. The stop ring 583 is elastically connected to the inner wall of the through groove 581 through a second spring 584; a first magnet 585 is provided on the stop ring 583, and a second magnet 586 that attracts the first magnet 585 is fixedly connected to the top of the through groove 581.

[0049] It should be noted that the attraction force of the first magnet 585 and the second magnet 586 is greater than the weight of the connecting block 55 and the protective plate 13, thus ensuring that the protective plate 13 will not fall automatically when it moves. The elasticity of the second spring 584 is greater than the reset resistance of the connecting block 55, ensuring that the connecting block 55 can reset. It is worth noting that the setting of the second spring 584 makes the first slider 52 move downward with greater resistance. Therefore, when the rotating ring 21 is turned, there will be greater resistance when it is turned to the point where the second slider 56 and the first slider 52 are in contact. When adjusting the position of the protective plate 13, the protective plate 13 will not easily unfold.

[0050] In use, the rotating ring 21 is turned, causing the T-shaped block 26 to slide within the slot 25 via transmission. When the T-shaped block 26 slides to the point where the first slider 52 and the second slider 56 abut, the rotating ring 21 is turned again. Since the second slider 56 is fixed within the slot 25, it will not slide. At this time, the first slider 52 slides downward, causing the connecting block 55 to slide downward, creating a gap between the protective plate 13 and the fixing ring 12. When the connecting block 55 moves completely to the underside of the T-shaped block 26, under the action of the second torsion spring, the connecting block 55 rotates away from the laser cutting head 11. At this time, the protective plate 13 unfolds. During the outward movement of the first slider 52, the moving column 582 moves downward, the stop ring 583 moves downward, and the second spring 584 gains elasticity so that after the first slider 52 and the second slider 56 separate, the first slider 52 resets, thereby driving the connecting block 55 to reset.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
