Description

Technical Field

[0001] This utility model relates to the field of pallet technology, and in particular to a front-to-back flip-up pallet. Background Technology

[0002] In automotive seat assembly lines, precise seat positioning is crucial for ensuring assembly accuracy and production efficiency. Automotive seats typically consist of multiple components, including a frame, seat cushion, backrest, and adjustment mechanism. Assembly involves numerous processes (such as welding, bolting, and fabric covering), each requiring the seat to be in a stable and precise position to ensure that the installation positions of each component meet design tolerances.

[0003] In existing production lines, seat positioning mostly relies on trays or simple tooling, but this has the following technical drawbacks.

[0004] On the one hand, the flipping mechanism of some flippable pallets is relatively complex, has high manufacturing costs, and is difficult to maintain; On the other hand, some flip-up trays have limited flipping angles, which cannot meet the placement needs of different items. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a front and rear flip-up tray, which overcomes the shortcomings of the prior art and effectively solves the problems of complex flipping mechanism, high manufacturing cost and limited flipping angle in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A front-to-back flip-up tray includes a base plate, with support columns welded to the top four corners of the base plate, and support plates welded to the top of each of the four support columns. U-shaped frames are welded to the outer walls of both ends of the support plates, and sliders are slidably connected to both sides of the two U-shaped frames. Movable plates are rotatably connected between adjacent sliders, and a first drive mechanism and a second drive mechanism are respectively connected to both sides of the two movable plates. The first drive mechanism includes a first U-shaped frame, a rotating tube rotatably connected to the inner walls of both ends of the first U-shaped frame, hexagonal rods respectively inserted and slidably connected to both ends of the rotating tube, worm gears respectively welded to and fixed to the ends of the two hexagonal rods that are far apart from each other, and a worm wheel meshing on the top of the worm gear. The second drive mechanism includes a second U-shaped frame, a bidirectional internally threaded tube rotatably connected to the inner walls of both ends of the second U-shaped frame, and threaded rods respectively screwed to both ends of the bidirectional internally threaded tube.

[0007] When the tray is in its initial state, the movable plate and the support plate are horizontally opposite. The object is placed on top of the support plate. At this time, both the first drive mechanism and the second drive mechanism are in a stopped state. Depending on the object, the first servo motor is started. The first servo motor drives the rotating tube to rotate through gear transmission. The rotating tube drives the worm to rotate through the hexagonal rod. Since the worm meshes with the worm wheel, the rotation of the worm will drive the rotation of the worm wheel, and the rotation of the worm wheel will drive the rotating shaft to rotate, thereby causing the movable plate to flip around the rotating shaft. By controlling the forward and reverse rotation and the rotation angle of the first servo motor, the movable plate can be flipped at any angle to meet the side support requirements of different objects. When adjusting the horizontal position according to the length of different objects, the second servo motor is activated. The second servo motor drives the bidirectional internal thread tube to rotate through gear transmission. The rotation of the bidirectional internal thread tube causes the two threaded rods to move simultaneously in opposite directions under the action of the bidirectional internal thread tube. The movement of the threaded rods drives the slider to slide in the T-shaped slide groove through the connecting block, thereby realizing the horizontal movement of the movable plate. By controlling the forward and reverse rotation and the rotation angle of the second servo motor, the horizontal movement distance and direction of the movable plate can be precisely controlled. In actual work, the first drive mechanism and the second drive mechanism can work together to realize the complex movement of the movable plate. For example, the movable plate can be moved horizontally while flipping, or it can be moved horizontally first and then flipped. This collaborative working mode can greatly improve the flexibility and efficiency of the pallet and meet the needs of object handling and processing in different scenarios.

[0008] Preferably, the outer walls on both sides of the U-shaped frame are provided with T-shaped grooves, and the T-shaped grooves and the slider form a sliding fit.

[0009] Preferably, a rotating shaft is welded and fixed to one end of each of the outer walls on both sides of the movable plate, and the rotating shaft and the slider form a rotational engagement.

[0010] Preferably, the first U-shaped frame is welded and fixed to one side of the outer wall of the support plate, and a first servo motor is installed and fixed on the inner wall of one end of the first U-shaped frame. The output shaft of the first servo motor and the outer wall of the rotating tube are both fitted with meshing gears.

[0011] Preferably, the worm gear is sleeved and fixed to one of the rotating shafts, and both ends of the worm's rod wall are rotatably connected to fixing blocks welded and fixed to both ends of the outer wall of one side of the slider.

[0012] Preferably, the second U-shaped frame is welded and fixed to the outer wall of the other side of the support plate, and a second servo motor is installed and fixed on the inner wall of one end of the second U-shaped frame. The output shaft of the second servo motor and the outer wall of the bidirectional internal thread tube are both fitted with meshing gears. The ends of the two threaded rods that are far apart from each other are rotatably connected to a connecting block welded and fixed to the outer wall of one side of the slider.

[0013] The beneficial effects of this utility model are as follows: 1. The rotating tube is driven to rotate by the first servo motor in the first drive mechanism. The rotating tube drives the worm gear to rotate through the hexagonal rod. The worm gear meshes with the worm wheel, thereby causing the worm wheel to drive the rotating shaft to rotate, realizing the flipping of the movable plate. This design allows the flipping angle of the movable plate to be adjusted as needed, which can meet the placement requirements of different objects. 2. The second servo motor in the second drive mechanism drives the bidirectional internal thread tube to rotate. The bidirectional internal thread tube drives the slider to slide within the T-shaped groove via the threaded rod, thereby realizing the horizontal movement of the movable plate. This design makes the movable plate more stable during horizontal movement and can adapt to the needs of objects of different lengths. 3. The overall structure of this utility model is simple, the connection between the components is reasonable, the manufacturing cost is low, and the maintenance is convenient. At the same time, the use of servo motor drive provides high control precision and can effectively improve work efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

Support plates 3 are welded and fixed to the top of the four support columns 2. U-shaped frames 4 are welded and fixed to the outer walls of both ends of the support plates 3. Slider 5 is slidably connected to both sides of the two U-shaped frames 4. Movable plates 7 are rotatably connected between two adjacent sliders 5. A first drive mechanism 8 and a second drive mechanism 9 are respectively connected to both sides of the two movable plates 7. The first drive mechanism 8 includes a first U-shaped frame 10, a rotating tube 11 rotatably connected to the inner walls of both ends of the first U-shaped frame 10, a hexagonal rod 13 inserted and slidably connected to both ends of the rotating tube 11, a worm gear 14 welded and fixed to the two hexagonal rods 13 at opposite ends, and a worm wheel 15 meshing on the top of the worm gear 14. The second drive mechanism 9 includes a second U-shaped frame 17, a bidirectional internal threaded tube 18 rotatably connected to the inner walls of both ends of the second U-shaped frame 17, and threaded rods 20 screwed to both ends of the bidirectional internal threaded tube 18. T-shaped grooves are provided on both outer walls of the U-shaped frame 4. The T-shaped grooves slide in conjunction with the slider 5. The base plate 1 serves as the basic support component for the entire pallet. Support columns 2 are welded and fixed at the four corners of its top. The support columns 2 are made of high-strength steel and can effectively support the support plate 3 above and the objects placed on the movable plate 7. Support plates 3 are welded and fixed to the top of the four support columns 2. The support plates 3 are rectangular flat plates and their function is to provide installation support for the U-shaped frame 4 and the drive mechanism. U-shaped frames 4 are welded and fixed to both outer walls of the support plates 3. T-shaped grooves are provided on both outer walls of the U-shaped frame 4. The bottom of the slider 5 is provided with T-shaped protrusions that match the T-shaped grooves. The T-shaped protrusions slide in conjunction with the T-shaped grooves. The T-shaped groove and the slider 5 are designed to allow the slider 5 to slide freely on both sides of the U-shaped frame 4. This T-shaped groove and slider 5 not only ensure the stability of the slider 5's sliding but also effectively prevent the slider 5 from falling off the U-shaped frame 4. A rotating shaft 6 is welded and fixed to one end of each side of the outer wall of the movable plate 7. The rotating shaft 6 and the slider 5 form a rotational engagement. A movable plate 7 is rotatably connected between each two adjacent sliders 5. A rotating shaft 6 is welded and fixed to one end of each side of the outer wall of the movable plate 7. The rotating shaft 6 and the slider 5 form a rotational engagement. This connection method allows the movable plate 7 to rotate around the rotating shaft 6, thereby realizing the rotation operation of the movable plate 7. The surface of the movable plate 7 is provided with anti-slip texture, which can effectively increase the friction between the object and the movable plate 7. The first U-shaped frame 10 is welded and fixed to one side of the outer wall of the support plate 3. The first servo motor 12 is installed and fixed to one end of the inner wall of the first U-shaped frame 10. The output shaft of the first servo motor 12 and the outer wall of the rotating tube 11 are both sleeved and fixed with meshing gears. The worm gear 15 is sleeved and fixed to one of the rotating shafts 6. The two ends of the worm 14 are rotatably connected to the fixing blocks 16 welded and fixed to the two ends of the outer wall of one side of the slider 5. The first drive mechanism 8 includes the first U-shaped frame 10, the rotating tube 11 rotatably connected to the inner walls of the two ends of the first U-shaped frame 10, the hexagonal rods 13 respectively inserted and sliding in the two ends of the rotating tube 11, the worm 14 respectively welded and fixed to the two hexagonal rods 13 at opposite ends, and the worm 14 meshing with the worm 14. 4.

The output shaft of the first servo motor 12 and the outer wall of the rotating tube 11 are both fitted with meshing gears. When the first servo motor 12 starts, it drives the rotating tube 11 to rotate through gear transmission. The rotating tube 11 has a hexagonal hole that matches the hexagonal rod 13, so that the hexagonal rod 13 can slide in the rotating tube 11 and rotate with the rotating tube 11. The rotation of the hexagonal rod 13 drives the worm gear 14 to rotate. The worm gear 14 meshes with the worm wheel 15, so that the worm wheel 15 drives the rotating shaft 6 to rotate, realizing the flipping of the movable plate 7. The second U-shaped frame 17 is welded and fixed to the outer wall of the other side of the support plate 3. A second servo motor 19 is installed and fixed to the inner wall of one end of the second U-shaped frame 17. The output shaft of the second servo motor 19 and the outer wall of the bidirectional internal threaded tube 18 are both sleeved and fixed with meshing gears. The ends of the two threaded rods 20 that are far apart from each other are rotatably connected to connecting blocks 21 welded and fixed to the outer wall of one side of the slider 5. The second drive mechanism 9 includes the second U-shaped frame 17, the bidirectional internal threaded tube 18 rotatably connected to the inner walls of both ends of the second U-shaped frame 17, and threaded rods 20 respectively screwed to the inner ends of the bidirectional internal threaded tube 18. The second U-shaped frame 17 is welded and fixed to the outer wall of the other side of the support plate 3, and the second servo motor 19 is installed and fixed to the inner wall of one end of the second U-shaped frame 17. The output shaft of the second servo motor 19 and the outer wall of the bidirectional internal threaded tube 18 are both sleeved and fixed. Fixed with meshing gears, when the second servo motor 19 starts, it drives the bidirectional internal thread tube 18 to rotate through gear transmission. The inner walls of both ends of the bidirectional internal thread tube 18 are respectively provided with left-hand threads and right-hand threads. The outer walls of the two threaded rods 20 are respectively provided with threads that are compatible with the threads at both ends of the bidirectional internal thread tube 18. When the bidirectional internal thread tube 18 rotates, the two threaded rods 20 will move in opposite directions simultaneously under the action of the bidirectional internal thread tube 18, thereby driving the slider 5 to slide in the T-shaped slide groove, realizing the horizontal movement of the movable plate 7. The ends of the two threaded rods 20 that are far apart from each other are rotatably connected to a connecting block 21 welded and fixed to one side of the outer wall of the slider 5. This rotatable connection method can ensure that the threaded rods 20 will not generate additional torque on the slider 5 during the movement, thereby ensuring the smooth sliding of the slider 5.

[0018] Working principle: When the tray is in its initial state, the movable plate 7 and the support plate 3 are horizontally opposite. The object is placed on top of the support plate 3. At this time, the first drive mechanism 8 and the second drive mechanism 9 are both in a stopped state. Depending on the object, the first servo motor 12 is started. The first servo motor 12 drives the rotating tube 11 to rotate through gear transmission. The rotating tube 11 drives the worm gear 14 to rotate through the hexagonal rod 13. Since the worm gear 14 meshes with the worm wheel 15, the rotation of the worm gear 14 will drive the worm wheel 15 to rotate. The rotation of the worm wheel 15 will drive the rotating shaft 6 to rotate, thereby causing the movable plate 7 to flip around the rotating shaft 6. By controlling the forward and reverse rotation and the rotation angle of the first servo motor 12, the movable plate 7 can be flipped at any angle within the range of 0°-180° to meet the side support requirements of different objects. When adjusting the horizontal position according to the length of different objects, the second servo motor 19 is activated. The second servo motor 19 drives the bidirectional internal thread tube 18 to rotate through gear transmission. The rotation of the bidirectional internal thread tube 18 causes the two threaded rods 20 to move simultaneously in opposite directions under the action of the bidirectional internal thread tube 18. The movement of the threaded rods 20 drives the slider 5 to slide in the T-shaped groove through the connecting block 21, thereby realizing the horizontal movement of the movable plate 7. By controlling the forward and reverse rotation and the rotation angle of the second servo motor 19, the horizontal movement distance and direction of the movable plate 7 can be precisely controlled. In actual work, the first drive mechanism 8 and the second drive mechanism 9 can work together to realize the complex movement of the movable plate 7. For example, the movable plate 7 can be rotated while moving horizontally, or it can be moved horizontally first and then rotated. This collaborative working mode can greatly improve the flexibility and efficiency of the pallet and meet the needs of object handling and processing in different scenarios.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
