Description

Technical Field

[0001] This invention relates to the field of automotive seat frame assembly technology, specifically to an automated automotive seat frame assembly production line. Background Technology

[0002] Car seat frames, typically made of metal, are the supporting structure of car seats. Their main function is to provide strength and stability to ensure the safety and comfort of occupants. The design and manufacture of car seat frames need to consider various factors, such as the shape, size, weight, strength requirements, and manufacturing processes of the seat. To efficiently and accurately assemble car seat frames, automated assembly lines are often used.

[0003] Automated assembly lines typically have multiple workstations, each equipped with specific equipment or robots to perform a particular assembly task. During production, the various components of the seat frame are automatically transported to their respective workstations for assembly. The precise operation of automated equipment ensures assembly accuracy and consistency, improving production efficiency and product quality. This production line may also possess advanced features such as real-time monitoring and quality inspection, as well as integration and data exchange with other production systems.

[0004] During the production of automotive seat frames, the car seats need to be rotated to achieve automated, all-around assembly. Existing automated assembly lines typically use specialized rotary fixtures for this rotation. However, this method requires additional equipment, which increases production costs and operational complexity. Therefore, an automated assembly line for automotive seat frames is proposed to address these issues. Summary of the Invention

Multiple racks are fixedly connected inside the crossbar. The outer wall of the racks meshes with the outer wall of the gear. A lifting assembly is provided on the top of the base plate. The lifting assembly is used to assemble the bottom of the car seat frame.

[0007] Preferably, the lifting assembly includes a hydraulic rod and a buffer seat, with the bottom of the hydraulic rod fixedly connected to the top of the base plate and the bottom of the buffer seat fixedly connected to the output end of the hydraulic rod.

[0008] Preferably, a plurality of dampers are fixedly connected to the top of the buffer seat, and a fixing plate is fixedly connected to the output end of the damper.

[0009] Preferably, a plurality of fixing blocks are fixedly connected to the bottom of the fixing plate one, a fixing plate two is fixedly connected to the top of the buffer seat, and a plurality of transmission rods one are rotatably connected to one side of the outer wall of the fixing blocks.

[0010] Preferably, a slider two is rotatably connected to one side of the transmission rod, multiple slide rails are fixedly connected to the top of the buffer seat, the bottom of the slider two is slidably connected to the outer wall of the slide rails, a slide rod is fixedly connected to one side of the outer wall of the slider two, and the outer wall of the slide rod is slidably connected to the inside of the fixed plate two.

[0011] Preferably, a rotating block one is rotatably connected to one side of the outer wall of the fixed block, a damper two is fixedly connected to one side of the outer wall of the rotating block one, a rotating block two is rotatably connected to one side of the outer wall of the slider two, and the output end of the damper two is fixedly connected to one side of the outer wall of the rotating block two.

[0012] Preferably, a spring is sleeved on the outer wall of the slide rod, one end of the spring is fixedly connected to one side of the outer wall of the second slide block, and the other end of the spring is fixedly connected to one side of the outer wall of the second fixing plate.

[0013] Preferably, a placement frame is fixedly connected to the top of the fixing plate, and a gripper is rotatably connected inside the placement frame.

[0014] Preferably, cylinders are fixedly connected to both sides of the top of the fixed plate, and push-pull plates are slidably connected to both sides of the inside of the placement frame, with one side of the outer wall of the push-pull plate fixedly connected to the output end of the cylinder.

[0015] Preferably, the push-pull plate has multiple sliding grooves II inside, the fixed plate I has multiple sliders I slidably connected inside, the top side of the slider I is fixedly connected to a column II, the outer wall of the column II is slidably connected inside the sliding groove II, one side of the slider I is rotatably connected to a transmission rod II, and one side of the transmission rod II is rotatably connected to one side of the gripper.

[0016] Working Principle: During the automatic assembly of the car seat frame, the car seat frame is first placed on the placement rack. A cylinder pulls a push-pull plate, which moves the slide rail two. The inner wall of the slide rail two moves the column two, which in turn pushes the slider one to slide outwards. The slider one then drives the gripper to rotate via the transmission rod two, thus pressing the outer wall of the car seat frame and fixing it in place. During production, a skid conveyor belt moves a moving plate, which in turn moves the bottom plate, thus moving the fixed car seat frame on it. This allows for the execution of each process. Simultaneously, a hydraulic rod drives the car seat frame to rise and fall, facilitating the assembly of the bottom of the car seat frame. As the moving plate moves, the gear at its bottom moves accordingly. Because the limiting post on the outer wall of the gear slides in the limiting groove on the inner wall of the crossbar, the buffer seat cannot rotate during movement. When the gear moves to the rack, the crossbar releases the restriction on the gear, allowing the gear to roll on the rack. As the gear rolls once, the limiting post slides back into the limiting groove, locking the mechanism. Simultaneously, one rotation of the gear drives the second irregularly shaped block to rotate once via the second rotating shaft. This rotation causes the fixing rod at the bottom of the second irregularly shaped block to rotate, allowing the first column on the fixing rod to slide into the first sliding groove inside the first irregularly shaped block. Pushed by the first column, the first irregularly shaped block rotates 90 degrees, which in turn drives the bottom plate at the top of the moving plate to rotate 90 degrees via the first rotating shaft, thus achieving the steering of the car seat frame. During assembly, in order to buffer the force on the car seat frame, the fixing plate 1 that fixes the car seat frame is connected to the buffer seat through the damper 1, thereby reducing and buffering the force on it. At the same time, when the fixing plate 1 is under force, the force is transmitted to the slider 2 through the transmission rod 1. The transmission process is buffered by the connection of the damper 2. After the force is transmitted to the slider 2, it will push the slider 2 to slide on the slide rail, thereby dispersing the force. During the sliding process of the slider 2, the spring will be compressed, thereby further buffering the force dispersion process.

[0017] This invention provides an automated assembly line for automotive seat frames. It offers the following advantages: 1. This invention moves the base plate by moving the moving plate. During the movement, the fixed block rotates by rolling on the rack, thereby causing the second irregular block to rotate. The second irregular block can then drive the first column on the fixed rod to rotate the first irregular block, which in turn drives the base plate to rotate. This allows the car seat frame on the base plate to be turned, solving the problem that other equipment is needed to assist in turning the car seat frame and improving the convenience of controlling the turning of the car seat frame in this automatic assembly line.

[0018] 2. This invention transmits force through a transmission rod, which in turn pushes the slider two to slide on the slide rail and eventually diffuses into the buffer seat. At the same time, the damper two and the spring provide buffering during the force transmission process, which can buffer the force on the car seat frame and thus improve the production quality of the car seat frame.

[0019] 3. The present invention drives the push-pull plate with a cylinder, which in turn drives the column two synchronously through the sliding groove two inside the push-pull plate. The column two then drives the slider one to slide, and finally the transmission rod two drives the gripper to rotate and press the outer wall of the car seat frame, thereby fixing the car seat frame. This improves the convenience of fixing the car seat frame and enhances the stability of the car seat frame during movement and processing. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example: Please refer to the appendix. Figure 1 - Appendix Figure 4 This invention provides an automated assembly line for automotive seat frames, comprising a skid conveyor belt 1, a movable plate 2 slidably connected to the top of the skid conveyor belt 1, a rotating shaft 11 rotatably connected inside the movable plate 2, a base plate 3 fixedly connected to the top of the rotating shaft 11, a shaped block 9 fixedly connected to the bottom of the outer wall of the rotating shaft 11, the shaped block 9 having an annular array of grooves 12 inside, a rotating shaft 16 rotatably connected to one side of the bottom of the movable plate 2, a shaped block 10 fixedly connected to the top of the outer wall of the rotating shaft 16, and a shaped block 10 at the bottom of the shaped block 10. A fixing rod 19 is fixedly connected to one side of the part, and a column 18 is fixedly connected to the top side of the fixing rod 19. The outer wall of the column 18 is slidably connected to the inside of the slide groove 12. A gear 15 is fixedly connected to the bottom of the outer wall of the rotating shaft 16. A limit post 17 is fixedly connected to one side of the inside of the gear 15. A crossbar 7 is fixedly connected to the inside of the skid conveyor belt 1. A limit groove 13 is opened inside the crossbar 7. The outer wall of the limit post 17 is slidably connected to the inside of the limit groove 13. Multiple racks 14 are fixedly connected to the inside of the crossbar 7. The outer wall of the rack 14 meshes with the outer wall of the gear 15.

[0024] The skid conveyor belt 1 is the driving force of the system, enabling the parallel movement of the seat frame by traction of the moving plate 2. The base plate 3 is fastened to the bottom of the moving plate 2, and the entire moving unit moves forward together, carrying the automotive seat frame. This synchronous movement mechanism allows the seat frame to smoothly transition between different workstations for various assembly and processing steps.

[0025] The function of hydraulic rod 4 is to adjust the height of the car seat frame, adapting to different assembly needs through raising and lowering. This height adjustment function is particularly important during assembly work at the bottom of the seat frame. This not only improves assembly flexibility but also ensures ergonomic comfort for workers during the assembly process.

[0026] During the movement of the movable plate 2, the gear 15 at its bottom rotates accordingly. A limiting post 17 is mounted on the outer wall of the gear 15, which slides within a limiting groove 13 on the inner wall of the crossbar 7. This design prevents arbitrary rotation of the gear during movement, ensuring the stability of the entire transmission system. When the gear 15 reaches the position of the rack 14, the crossbar 7 releases its restraint on the gear, allowing it to roll freely on the rack. After one revolution of the gear on the rack, the limiting post 17 slides back into the limiting groove 13, thereby relocking the mechanism and maintaining the system's synchronization and safety.

[0027] Furthermore, the rotation of gear 15 drives the rotation of shaped block 10 via rotating shaft 16. The fixing rod 19 at the bottom of shaped block 10 also rotates, causing column 18 to slide into the groove 12 inside shaped block 9. The push of column 18 causes shaped block 9 to rotate 90 degrees, which is transmitted to the base plate 3 on top of moving plate 2 via rotating shaft 11, causing base plate 3 to rotate 90 degrees accordingly. This steering mechanism provides directional adjustment for the car seat frame, adapting to assembly requirements in different directions and improving the flexibility and efficiency of the production line. The entire system is designed with precise control and mechanical efficiency in mind, ensuring continuity and reliability in the production process.

[0028] Please see the appendix Figure 5 - Appendix Figure 6 The lifting assembly includes a hydraulic rod 4 and a buffer seat 5. The bottom of the hydraulic rod 4 is fixedly connected to the top of the base plate 3. The bottom of the buffer seat 5 is fixedly connected to the output end of the hydraulic rod 4. Multiple dampers 8 are fixedly connected to the top of the buffer seat 5. A fixed plate 6 is fixedly connected to the output end of the dampers 8. Multiple fixed blocks 25 are fixedly connected to the bottom of the fixed plate 6. A fixed plate 24 is fixedly connected to the top of the buffer seat 5. Multiple transmission rods 30 are rotatably connected to one side of the outer wall of the fixed block 25. A slider 37 is rotatably connected to one side of the transmission rods 30.

A rotating block 28 is rotatably connected to one side of the outer wall of the fixed block 25. A damper 21 is fixedly connected to one side of the outer wall of the rotating block 28. A rotating block 29 is rotatably connected to one side of the outer wall of the slide rail 27. The output end of the damper 21 is fixedly connected to one side of the outer wall of the rotating block 29. A spring 27 is sleeved on the outer wall of the sliding rod 26. One end of the spring 27 is fixedly connected to one side of the outer wall of the slide rail 27, and the other end of the spring 27 is fixedly connected to one side of the outer wall of the fixed plate 24.

[0029] In the assembly of automotive seat frames, precise force management and shock absorption mechanisms are crucial to ensure assembly quality and extend the service life of the finished product. The fixing plate 6, which secures the automotive seat frame, is a key component in this mechanism; it is connected to the buffer seat 5 via a damper 8. This configuration allows the fixing plate 6 to effectively absorb and cushion shocks when subjected to force, thereby protecting the seat frame from excessive impact and stress, and enhancing the product's durability and safety.

[0030] When the fixed plate 6 is subjected to force, the force is transmitted to the slider 37 via the transmission rod 30. The transmission rod 30 is designed to transmit the force evenly, and the damper 21 connected to it further reduces vibration during this transmission process, effectively absorbing and dispersing the power transmitted from the fixed plate 6. This design not only protects the integrity of the mechanical structure but also optimizes the smoothness of the assembly line operation.

[0031] After the force is transmitted to slider 37, it will cause slider 37 to slide on slide rail 20. Slide rail 20 provides slider 37 with a stable sliding path, allowing it to move smoothly while receiving force. This sliding not only helps to further distribute the force, but also protects the structural safety of the seat frame by reducing local stress concentration.

[0032] During the sliding of slider 2 (37), the connected spring 27 is compressed. This compression provides additional cushioning for the entire force distribution process. The compression and release of spring 27 not only provides the necessary reaction force to help slider 2 (37) return to its initial position, but also plays an important role in shock absorption, further mitigating the impact force during transmission. This comprehensive cushioning and shock absorption mechanism ensures precision and safety during assembly, while also reducing wear and tear during production, extending the overall service life of the product.

[0033] Please see the appendix Figure 7 - Appendix Figure 8 A placement rack 22 is fixedly connected to the top of the fixed plate 6. A gripper 23 is rotatably connected inside the placement rack 22. Cylinders 36 are fixedly connected to both sides of the top of the fixed plate 6. Push-pull plates 31 are slidably connected to both sides of the inside of the placement rack 22. One side of the outer wall of the push-pull plate 31 is fixedly connected to the output end of the cylinder 36. Multiple sliding grooves 32 are opened inside the push-pull plate 31. Multiple sliders 34 are slidably connected inside the fixed plate 6. A column 33 is fixedly connected to one side of the top of the slider 34. The outer wall of the column 33 is slidably connected inside the sliding groove 32. A transmission rod 35 is rotatably connected to one side of the slider 34. One side of the transmission rod 35 is rotatably connected to one side of the gripper 23.

[0034] In automated automotive seat frame assembly lines, the use of highly precise mechanical systems to ensure the stability and assembly quality of the seat frame is crucial. This process begins with placing the automotive seat frame onto the mounting rack 22. The mounting rack 22 provides an initial anchor point for the seat frame, ensuring its accurate positioning during assembly.

[0035] The cylinder 36 drives the push-pull plate 31, causing it to move along a designated path. The design of the push-pull plate 31 allows it to move smoothly in a straight line, which directly affects other mechanical components connected to it. As the push-pull plate 31 moves, the slide rail 32, which is structurally connected to it, also moves accordingly. The slide rail 32 is a key component; its inner wall design allows the column 33 to slide along a predetermined trajectory within it.

[0036] The movement of column 2 33 is crucial to the entire assembly process because it directly drives slider 1 34. Slider 1 34 slides outward along a set track, achieved through precise mechanical force transmission. As slider 1 34 moves, transmission rod 2 35 is activated, which drives gripper 23 to rotate via its mechanical connection.

[0037] The rotation of gripper 23 is the final action in this automated assembly process. Its function is to firmly grasp the outer wall of the car seat frame, ensuring that the seat frame remains stable in subsequent assembly steps. The design of gripper 23 allows it to apply uniform pressure to the seat frame, thereby avoiding damage to the seat frame while ensuring its accurate positioning during assembly. This automated clamping mechanism not only improves assembly efficiency but also enhances product consistency and quality, making the entire production line operate more smoothly and efficiently.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
