Description

Technical Field

[0001] This utility model relates to the field of airbag production equipment, and in particular to a production positioning device for automotive seat airbags. Background Technology

[0002] In today's booming automotive industry, vehicle safety performance has increasingly become a focus of consumer attention. As a key component ensuring the safety of drivers and passengers, the production quality of car seat airbags directly affects their protective effect in the event of an accident. Precise positioning is a crucial step in ensuring product quality during the production process of car seat airbags. The performance of the production positioning device determines whether the airbag can maintain a stable state during subsequent processing, thereby meeting stringent production process requirements.

[0003] Currently, the production process of automotive seat airbags involves multiple steps, and in the sewing process, traditional equipment often lacks a dedicated airbag positioning component. Therefore, workers need to directly squeeze and fix the airbag with their hands during sewing to maintain it in the correct position and ensure that the suture thread is accurately sewn along the preset trajectory. During the operation, workers must keep their hands stable throughout, pressing the airbag to prevent it from moving while controlling the sewing equipment. This method of relying on manual hand fixation has become a key positioning method in the production process.

[0004] However, this method of relying solely on workers' hands to fix the airbag has significant drawbacks. Because manual operation is difficult to maintain absolute stability for extended periods, even slight hand tremors or unconscious movements due to fatigue can easily cause the airbag to shift position. If the airbag deviates during the sewing process, it not only causes twisted or misaligned stitches, reducing the product's appearance quality and structural strength and significantly increasing the defect rate, but also affects the airbag's deployment performance due to the shifted internal structure during sewing. This results in the finished product failing to provide proper safety protection in actual use, creating serious safety hazards and posing a significant risk to the safety performance of subsequent vehicles. Therefore, a production positioning device for automotive seat airbags is proposed to address these problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-5 An embodiment of this utility model is provided: a production positioning device for automobile seat airbags, including a placement platform 1. Multiple rubber extrusion plates 7 are symmetrically distributed on the top of the placement platform 1. The rubber extrusion plates 7 are used to directly contact and extrude the surface of the airbag, and adapt to airbags of different shapes through their elastic deformation to ensure positioning stability. The outer walls of the multiple rubber extrusion plates 7 are provided with moving components, which are used to adjust the position of the rubber extrusion plates 7 to adapt to the positioning requirements of airbags of different sizes.

[0035] The moving assembly includes multiple rotating shafts 3 and rotating plates 4. The rotating shafts 3, in conjunction with the rotating plates 4, rotate to achieve the angle adjustment function of the rubber extrusion plate 7. Each rotating shaft 3 and rotating plate 4 is located on top of the rubber extrusion plate 7. Multiple symmetrically distributed fixing frames 2 are fixedly connected to the top of the placement platform 1. The fixing frames 2 support the rotating shafts 3 and provide a fulcrum for rotation, ensuring the stable rotation of the rotating plates 4. Each fixing frame 2 is internally fixedly connected to the outer wall of the rotating shaft 3, and the outer wall of each rotating shaft 3 is rotatably connected to the inner wall of the rotating plate 4. The rotating plates 4 drive the connecting plates 5 to move synchronously, thereby adjusting the lateral position of the rubber extrusion plate 7. Each rotating plate 4 has a connecting plate 5 fixedly connected to one side. The connecting plates 5 connect the rotating plates 4 and the rubber extrusion plate 7, transmit the adjustment force, and maintain structural linkage. Each connecting plate 5 is internally equipped with a spring 24. The spring 24 buffers the pressure between the rubber extrusion plate 7 and the airbag, preventing excessive compression and damage to the airbag surface. One end of each spring 24 is fixedly connected to a transmission block 6, which transmits the spring force of the spring 24 to the rubber extrusion plate 7, achieving dynamic pressure adjustment. The other end of each spring 24 is fixedly connected to the inner wall of the connecting plate 5. The bottom of each transmission block 6 is fixedly connected to the top of the rubber extrusion plate 7. Each rotating plate 4 has a fixing component on its outer wall. This component locks the rotational position of the rotating plate 4, ensuring the fixed state of the rubber extrusion plate 7 and the airbag. Each fixing component includes a locking plate 13, which engages with a locking groove 8 to achieve mechanical locking, preventing accidental rebound of the rotating plate 4. Each locking plate 13 is located inside the rotating plate 4. Each rotating plate 4 has a locking groove 8 inside, which is used to accommodate the locking plate 13 and provide a locking contact surface to enhance positioning reliability. Each locking plate 13 is provided with multiple springs 15 inside. The springs 15 are used to push the locking ball 14 to maintain the locking state and ensure the durability of the locking mechanism. One end of each spring 15 is fixedly connected to the inner wall of the locking plate 13, and the other end of each spring 15 is fixedly connected to the locking ball 14. The locking ball 14 is used to form a point contact lock with the inner wall of the locking groove 8 to reduce friction loss and improve sensitivity. Both the locking plate 13 and the locking ball 14 are engaged with the inner wall of the locking groove 8. Each fixing bracket 2 has a fixing block 9 fixedly connected to one side. The fixing block 9 is used to support the connecting column 12 and provide rotation space. Each card plate 13 has a connecting post 12 fixedly connected to its inner wall. The connecting post 12 is used to connect the card plate 13 and the rotating post 10 to transmit rotational torque. Each connecting post 12 has a rotating post 10 fixedly connected to its bottom. The rotating post 10 is used to drive the limiting ring 11 to rotate and achieve axial positioning. Each rotating post 10 has a limiting ring 11 fixedly connected to its outer wall. The limiting ring 11 is used to limit the axial displacement of the rotating post 10 and ensure rotational stability. Each rotating post 10 and the limiting ring 11 are rotatably connected to the inside of the fixed block 9. Each transmission block 6 is slidably connected to the inner wall of the connecting plate 5. The top of each fixed block 9 is in contact with the bottom of the rotating plate 4. Each connecting plate 5 has an adjustment component on its outer wall. The adjustment component is used to finely adjust the lateral position of the rubber extrusion plate 7 to adapt to different airbag sizes.

[0036] Reference Figure 2 and Figure 4 Each adjustment component includes multiple sliders 18. Slider 18 drives connecting block 16 to slide along fixed block 2 17, achieving lateral displacement of connecting plate 5. Multiple sliders 18 are located on both sides of connecting plate 5. Connecting blocks 16 are fixedly connected to both sides of each connecting plate 5, connecting blocks 16 connect sliders 18 to connecting plate 5, transmitting lateral adjustment force. One side of each connecting block 16 is fixedly connected to the outer wall of slider 18. A fixed block 2 17 is slidably connected to the outer wall of each slider 18, providing a sliding track for slider 18 to ensure movement accuracy. Multiple fixed blocks 2 17 are fixedly connected to both sides of rotating plate 4. A fixed shell 19 is fixedly connected to one side of each fixed block 2 17, accommodating transmission column 20 and providing sliding space. In each fixed shell 19, a transmission column 20 is slidably connected to the inner wall. The transmission column 20 is used to drive the locking block 23 to disengage from the slider 18 and release the position lock. A pull rod 21 is fixedly connected inside each transmission column 20. The pull rod 21 is used for manual operation to move the transmission column 20 for quick adjustment. A locking block 23 is fixedly connected to one end of each transmission column 20. The locking block 23 is used to engage with the inner wall of the slider 18 to fix the position. Each locking block 23 engages with the inside of the slider 18. A second spring 22 is provided on the outer wall of each transmission column 20. The second spring 22 is used to push the locking block 23 to automatically reset and achieve quick locking. One end of each second spring 22 is fixedly connected to one side of the inner wall of the fixed shell 19, and the other end of each second spring 22 is fixedly connected to the outer wall of the locking block 23.

[0037] Working principle: During the positioning of the airbag, pulling the two pull rods 21 causes the locking block 23 at one end of the transmission column 20 to separate from the inner wall of the slider 18. As the locking block 23 moves, it compresses the second spring 22, subsequently pushing the connecting plate 5 to move. During this movement, the connecting plate 5, through the connecting block 16, causes the slider 18 to slide against the inner wall of the second fixed block 17 until the rubber extrusion plate 7 is moved to the designated position. Then, the pulling force on the pull rod 21 is released, and the rebound force of the second spring 22 pushes the locking block 23 to engage again with the inside of the slider 18, thus fixing the position of the rubber extrusion plate 7 and achieving the effect of adjusting the position of the rubber extrusion plate 7. Compared with traditional equipment, this method has significantly enhanced adaptability. Next, the rotating plate 4 is pushed to rotate around the rotating shaft 3 until the bottom of the rotating plate 4 is in contact with the top of the first fixed block 9. At this point, the bottom of the rubber extrusion plate 7 is in contact with the airbag, and the outer wall of the airbag pushes the transmission block 6 at the top of the rubber extrusion plate 7 to slide against the inner wall of the connecting plate 5, causing the airbag to move. Spring 24 is compressed, and its rebound force is used to push this force back to the surface of the rubber extrusion plate 7, so that the rubber extrusion plate 7 and the airbag are fully compressed and fixed. Next, the connecting column 12 is rotated, so that the clamping plate 13 rotates to the inner wall of the clamping groove 8. The rotating column 10 drives the limiting ring 11 to rotate on the inner wall of the fixing block 9, which limits the position of the connecting column 12. When the clamping plate 13 moves to the inner wall of the clamping groove 8, the inner wall of the clamping groove 8 will squeeze the clamping ball 14, so that the clamping ball 14 moves into the clamping plate 13 and compresses the spring 15. When the clamping ball 14 moves to the specific groove, the rebound force of the spring 15 pushes the clamping ball 14 to engage with the inner wall of the clamping groove 8, thereby fixing the position of the rubber extrusion plate 7 and achieving a good positioning effect for the airbag. This solves the problem that when workers usually use their hands to squeeze and position the airbag during airbag sewing, the position of the airbag is easily shifted due to the movement of the workers' hands. This enhances the stability of the equipment in positioning the airbag.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
