[0014] A further technical solution is that the suction cup assembly further includes a suction cup bracket, a drive rod, a connecting rod, and a crossbar; the suction cup bracket is mounted on the robotic arm; the drive rod is connected to a motor; two connecting rods are symmetrically arranged on the drive rod around its rotation axis; the end of the connecting rod away from the drive rod is connected to the crossbar; the crossbar is slidably connected to the suction cup bracket; and the vacuum suction cup is mounted on the crossbar.

[0015] A further technical solution is that the suction cup bracket is provided with a slide rail and a slider that is slidably connected to the slide rail; the crossbar is slidably connected to the suction cup bracket through the slide rail and the slider.

[0016] A further technical solution is that one of the crossbars connects two of the slide rails; the two slide rails are arranged in parallel.

[0017] A further technical solution is that the connecting rod includes an upper lifting ring rotatably connected to the drive rod, a lower lifting ring rotatably connected to the crossbar, and an adjusting screw disposed between the upper lifting ring and the lower lifting ring; the adjusting screw is threadedly connected to the upper lifting ring and the lower lifting ring.

[0022] The beneficial technical effects of this utility model are as follows:

[0023] (1) The car floor transfer device of this utility model is equipped with a conveying mechanism and a robotic arm. The conveying mechanism moves the position of the car floor over a large range, and the robotic arm loads and unloads the car floor in a small range, realizing the automated transfer of the car floor. Automated transfer reduces manual intervention and significantly reduces the transportation cost of the car floor. The robotic arm uses a vacuum suction cup to adsorb and fix the car floor, avoiding damage to the car floor by the mechanical fixing method. In addition, the conveyor frame is also equipped with adjusting wheels. When the car floor is conveyed on the roller, the adjusting wheels contact the side of the floor and limit the horizontal position of the car floor on the roller. At the same time, the adjusting wheels and the car floor have rolling friction, which reduces friction loss during the car floor transportation process. The adjusting wheels are connected to the conveyor frame through adjusting screws. Rotating the adjusting screws moves the adjusting blocks on the adjusting screws along the length of the adjusting screws, thereby quickly moving the position of the adjusting wheels. When transferring car floors of different sizes through the conveying mechanism, only the adjusting screw needs to be rotated to adapt to car floors of different sizes, limit the movement path of the car floor, and ensure that the robotic arm accurately clamps the car floor.

[0024] (2) Furthermore, a guide rod is also provided on the conveyor frame. When the adjusting block moves along the adjusting screw, the guide rod restricts the position of the adjusting block to ensure that the adjusting block moves along the length direction of the adjusting screw.

[0025] (3) Further, the vacuum suction cup is mounted on the crossbar, which is connected to the drive rod via a connecting rod. When the drive rod rotates, it simultaneously drives the two connecting rods to move, thereby driving the two crossbars to move symmetrically around the rotation axis of the drive rod. When adsorbing the car floor using the vacuum suction cup, as long as the center of the robotic arm and the car floor are aligned, the car floor can be stably adsorbed via the two crossbars.

[0035] Figure 1 A front view structural schematic diagram of a vehicle floor transfer device according to an embodiment of the present disclosure is shown. Figure 2 A schematic diagram of the structure of the adjusting wheel is shown in a vehicle floor transfer device according to an embodiment of the present disclosure. Figure 3 A partially enlarged view of a vehicle floor transfer device according to an embodiment of this disclosure is shown at point A. Please refer to... Figure 1 , Figure 2 and Figure 3The car floor transfer device includes a conveying mechanism 1, adjusting wheels 2, and robotic arms 3. The conveying mechanism 1 includes a conveyor frame 11 and rollers 12 mounted on it, with adjacent rollers 12 arranged horizontally and parallel to each other. A motor 5 is connected to each roller 12. Adjusting wheels 2 are located on the width side of the conveyor frame 11 and above the rollers 12. The rotation shaft 23 of the adjusting wheels 2 is vertically positioned. Two robotic arms 3 are positioned along the length of the conveying mechanism 1 on its sides. By moving the car floor over a wide area using the conveying mechanism 1 and then loading and unloading it using the robotic arms 3, automated transfer of the car floor is achieved, reducing manual intervention and significantly lowering transportation costs. Suction cup assemblies 4 are mounted on the robotic arms 3. The suction cup assemblies 45 include vacuum suction cups. The robotic arms 3 use the vacuum suction cups 45 to adhere and fix the car floor, avoiding damage to the car floor caused by mechanical fixing methods.

[0036] The conveyor frame 11 is equipped with an adjusting screw 21, which is parallel to the roller 12. An adjusting block 22 is threaded onto the adjusting screw 21. An adjusting wheel 2 is rotatably mounted on the adjusting block 22. Rotating the adjusting screw 21 adjusts the horizontal position of the adjusting wheel 2, thus limiting the position of the product on the roller 12. When the car floor is conveyed on the roller 12, the adjusting wheel 2 contacts the side of the floor, limiting the horizontal position of the car floor on the roller 12. Simultaneously, the adjusting wheel 2 and the car floor experience rolling friction, reducing friction loss during conveying. The adjusting wheel 2 is connected to the conveyor frame 11 via the adjusting screw 21. Rotating the adjusting screw 21 moves the adjusting block 22 along the length of the adjusting screw 21, thereby rapidly moving the position of the adjusting wheel 2. When conveying car floors of different sizes via the conveyor mechanism 1, simply rotating the adjusting screw 21 adapts to different sizes of car floors, limiting their movement path and ensuring the robotic arm 3 accurately grips the car floor.

[0037] Figure 4 The diagram shows a left-side view of the robotic arm in a vehicle floor transfer device according to an embodiment of this disclosure. Please refer to... Figure 1 and Figure 4The suction cup assembly 4 also includes a suction cup bracket 41, a drive rod 42, connecting rods 43, and a crossbar 44. The suction cup bracket 41 is mounted on the robotic arm 3. The drive rod 42 is connected to a motor 5. Two connecting rods 43 are symmetrically arranged on the drive rod 42 around its rotation axis 23. The ends of the two connecting rods 43 away from the drive rod 42 are connected to the crossbar 44. The crossbar 44 is slidably connected to the suction cup bracket 41. A vacuum suction cup 45 is mounted on the crossbar 44. When the drive rod 42 rotates, it simultaneously drives the two connecting rods 43 to move, thereby driving the two crossbars 44 to move symmetrically around the rotation axis 23 of the drive rod 42. When the vacuum suction cup 45 is used to adsorb the car floor, as long as the centers of the robotic arm 3 and the car floor are aligned, the car floor can be stably adsorbed by the two crossbars 44.

[0038] Preferably, the suction cup bracket 41 is provided with a slide rail 411 and a slider 412 that is slidably connected to the slide rail 411. The crossbar 44 is slidably connected to the suction cup bracket 41 via the slide rail 411 and the slider 412, which facilitates the adjustment of the position of the vacuum suction cup 45 on the suction cup bracket 41 to stably adsorb car flooring of different sizes.

[0039] More preferably, one crossbar 44 is connected to two slide rails 411, which are arranged in parallel. The movement of the crossbar 44 is restricted by the two slide rails 411, thereby improving the stability of the crossbar 44 during movement.

[0040] Please refer to Figure 1 and Figure 4 The connecting rod 43 includes an upper lifting ring 431 rotatably connected to the drive rod 42, a lower lifting ring 432 rotatably connected to the crossbar 44, and an adjusting screw 433 disposed between the upper lifting ring 431 and the lower lifting ring 432. The adjusting screw 433 is threadedly connected to the upper lifting ring 431 and the lower lifting ring 432. In this embodiment, threaded holes are respectively provided on the upper lifting ring 431 and the lower lifting ring 432. The adjusting screw 433 extends into the threaded hole and is threadedly connected to the upper lifting ring 431 and the lower lifting ring 432. By adjusting the depth of the adjusting screw 433 extending into the threaded hole, the overall length of the connecting rod 43 can be quickly adjusted, allowing the crossbar 44 to slide along the slide rail 411 for a greater stroke.

[0041] Preferably, the vacuum suction cup 45 is connected to a suction cup screw 451. An upper nut 452 and a lower nut 453 are provided on the suction cup screw 451. When the vacuum suction cup 45 is mounted on the crossbar 44, the suction cup screw 451 passes through the crossbar 44. The crossbar 44 is positioned between the upper nut 452 and the lower nut 453. By rotating the upper nut 452 and the lower nut 453 around the suction cup screw 451, the distance between the upper nut 452 and the lower nut 453 can be adjusted to fix the vacuum suction cup 45 on the crossbar 44 or to remove the vacuum suction cup 45 from the crossbar 44.

[0042] More preferably, along the length of the crossbar 44, several through holes are provided on the crossbar 44 for the suction cup screw 451 to pass through. By allowing the suction cup screw 451 to pass through the through holes at different positions on the crossbar 44, the vacuum suction cup 45 can be fixed at different positions on the crossbar 44, improving the flexibility of the vacuum suction cup 45 layout.

[0043] Figure 5 A partially enlarged view of a vehicle floor transfer device according to an embodiment of this disclosure is shown at point B. Please refer to... Figure 1 , Figure 2 and Figure 5 The conveyor frame 11 is also equipped with a guide rod 24. The guide rod 24 is parallel to the adjusting screw 21. The guide rod 24 passes through the adjusting block 22. When the adjusting block 22 moves along the adjusting screw 21, the guide rod 24 restricts the position of the adjusting block 22, ensuring that the adjusting block 22 moves along the length direction of the adjusting screw 21.

[0044] Preferably, the conveying mechanism 1 further includes a chain 13. A gear 121 is provided at the end of the length of the roller 12. Multiple rollers 12 are connected to the chain 13 via the gear 121, so that the motor 5 can be directly connected to and drive one roller 12, thereby simultaneously driving all the rollers 12 on the entire conveying mechanism 1.

[0045] More preferably, the robotic arm 3 includes a base 31, a rotating seat 32 rotatably mounted on the base 31, a large arm 33 rotatably connected to the rotating seat 32, and a small arm 34 rotatably connected to the large arm 33. A suction cup assembly 4 is disposed at one end of the small arm 34, adjacent to the large arm 33. The rotation axis 23 is vertical, while the rotation axes 23 of the large arm 33 and the small arm 34 are horizontal, allowing the suction cup assembly 4 driven by the robotic arm 3 to move flexibly in three-dimensional space, facilitating the robotic arm 3 to adhere to the car floor and place it in a designated position.

[0046] The specific workflow of this utility model is as follows:

[0047] First, based on the dimensions of the car floor, the operator rotates the adjusting screw 21 to move the position of the adjusting wheel 2 to adapt to the dimensions of the car floor. Simultaneously, the drive rod 42 is rotated, causing the connecting rod 43 to move, which in turn drives the crossbar 44 to slide along the slide rail 411, adjusting the distance between the two crossbars 44 to fit the dimensions of the car floor. Then, the motor 5 drives the roller 12 to rotate. Next, the rotating seat 32 of the first robotic arm 3 rotates around the base 31, the upper arm 33 rotates around the rotating seat 32, and the lower arm 34 rotates around the upper arm 33, moving the vacuum suction cup 45 to contact and adhere to the car floor, moving the car floor onto the roller 12. The roller 12 continues to rotate, causing the car floor supported by the roller 12 to move along the conveying mechanism 1 to the working range of the second robotic arm. The rotating seat 32 of the second robotic arm 3 rotates around the base 31, the upper arm 33 rotates around the rotating seat 32, and the lower arm 34 rotates around the upper arm 33, moving the vacuum suction cup 45 to contact and adhere to the car floor, removing the car floor from the conveying mechanism 1. This completes the transfer of the car floor.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
