[0040] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] The embodiment of the present application provides a frame flipping mechanism, which can solve the problems in the related art of difficult operation and low flipping efficiency when flipping the frame.

[0042] See also Figure 1 、 Figure 6 and Figure 7 As shown, an embodiment of the present application provides a frame flipping mechanism, including a gantry assembly 2, a flipping mechanism body 4 and a clamping assembly 5, the gantry assembly 2 includes longitudinal beams 21 on both sides and a cross beam 22 fixed between the two longitudinal beams 21; the flipping mechanism body 4 is fixed to the gantry assembly 2, and is used to drive the frame to flip, which includes a hollow roller 43 with a side opening, and a flipping assembly for driving the roller 43 to rotate; the clamping assembly 5 includes a mounting seat 51 fixed to the roller 43, and a clamping member rotatably connected to the mounting seat 51, for limiting the position of the frame in the height direction.

[0043] In actual use, the gantry assembly 2 includes longitudinal beams 21 on both sides and a crossbeam 22 fixed between the two longitudinal beams 21, which constitute the main support structure of the entire flipping mechanism. The gantry assembly 2 provides a stable support structure for the entire device. The fixed connection between the longitudinal beams 21 and the crossbeam 22 ensures the stability of the device, allowing the flipping mechanism body 4 and the clamping assembly 5 to be safely installed and operate. The flipping mechanism body 4 includes a hollow roller 43 with a side opening and a flipping assembly for driving the roller 43 to rotate. The flipping mechanism body 4 is fixed to the gantry assembly 2. The hollow design and side opening of the roller 43 allow the frame to be easily put in and out, which is convenient for improving the flipping efficiency. At the same time, the flipping assembly can drive the roller 43 to rotate, thereby driving the frame to flip. The flipping mechanism body 4 is the main component that drives the frame to flip. Through the rotation of the roller 43, the frame can be safely and smoothly flipped to the desired angle, which is convenient for subsequent processing or inspection. The clamping assembly 5 includes a mounting seat 51 fixed to the roller 43 and a clamping member rotatably connected to the mounting seat 51. The clamping assembly 5 is fixed to the roller 43 through the mounting seat 51, and the clamping member is rotatably connected to the mounting seat 51. When the frame is placed in the roller 43, the clamping member can be rotated to an appropriate position and limit the frame in the height direction to prevent it from moving or slipping during the flipping process. The clamping assembly 5 ensures the stability and safety of the frame during the flipping process. Through the limiting action of the clamping member, the frame is firmly fixed to the roller 43 and can maintain a stable state even during the flipping process. The flipping mechanism of the present application can improve the flipping efficiency while meeting the safety of the frame during flipping.

[0044] In some optional embodiments, such as Figure 1 、 Figures 7 to 10 As shown, the flip assembly includes an arc-shaped rack 44 fixed to the roller 43, and a first gear 45 meshing with the rack 44. A power assembly is connected to the first gear 45 to drive the first gear 45 for rotation. The power assembly includes a drive gear 46 meshing with the first gear 45, and a drive motor 47 that drives the drive gear 46 for rotation. The flip assembly includes an arc-shaped rack 44 fixed to the roller 43, and the first gear 45 meshing with the rack 44. The rack 44 is arc-shaped and fixed to the outer surface, i.e., the periphery, of the roller 43. The rack 44 extends along the circumference of the roller 43, and its teeth mesh with the teeth of the first gear 45. The first gear 45 meshes with the rack 44. When the first gear 45 rotates, the rack 44 guides the roller 43, causing it to rotate, thereby flipping the vehicle frame. The flip assembly converts the rotational motion of the power assembly into the rotational motion of the roller 43 through the meshing transmission of the rack 44 and the first gear 45. This design makes the flipping process more stable and accurate, and can withstand a larger flipping torque.

[0045] The power assembly includes a driving gear 46 meshing with the first gear 45 and a driving motor 47 that drives the driving gear 46 to rotate. The driving gear 46 meshes with the first gear 45. When the driving gear 46 rotates, it can drive the first gear 45 to rotate, and then drive the roller 43 to flip through the flip assembly. The driving motor 47 serves as a power source and drives the driving gear 46 to rotate through the output shaft. The speed and direction of the driving motor 47 can be adjusted by the control system to achieve precise flipping of the roller 43. The power assembly provides the necessary power source for the flipping mechanism body 4. Through the drive of the driving motor 47, the flipping speed and flipping angle of the roller 43 can be precisely controlled to meet various needs during the frame flipping process.

[0046] The flip assembly and the power assembly work closely together to realize the flipping function of the frame. The meshing transmission of the rack 44 and the first gear 45 ensures the smooth rotation of the roller 43, while the meshing transmission of the drive gear 46 and the drive motor 47 provides the necessary power source. The coordinated work of these components enables the entire flipping mechanism body 4 to complete the flipping task of the frame efficiently and accurately. Through the coordinated action of the flip assembly and the power assembly, this optional embodiment provides an efficient and stable frame flipping solution. It not only improves the accuracy and efficiency of the frame flipping, but also reduces the labor intensity of the workers and improves work safety. At the same time, due to the use of a gear transmission method, the solution also has good load-bearing capacity and durability, and is suitable for frame flipping needs of various sizes.

[0047] In some optional embodiments, such as Figure 10 As shown, the clamping member includes a first clamping plate 52 rotatably connected to the mounting seat 51 and a second clamping plate 54 rotatably connected to the mounting seat 51 and spaced apart from the first clamping plate 52 along the height direction. The first clamping plate 52 and the second clamping plate 54 are arranged opposite to each other.

[0048] In some optional embodiments, such as Figures 7 to 10 As shown, the first clamping plate 52 is provided with a first cylinder 521 for driving the first clamping plate 52 to rotate. The first clamping plate 52 includes a first connecting section 522 rotatably connected to the first cylinder 521, a second connecting section 523 rotatably connected to the mounting seat 51, and a first abutting section 524 for abutting against the limiting frame.

[0049] The second clamping plate 54 is provided with a second cylinder 541 for driving the second clamping plate 54 to rotate. The second clamping plate 54 includes a third connecting section 542 rotatably connected to the second cylinder 541, a fourth connecting section 543 rotatably connected to the mounting seat 51, and a second contact section 544 for contacting the limiting frame.

[0050] The clamping assembly 5 includes a first clamping plate 52 and a second clamping plate 54 rotatably connected to the mounting base 51. The first clamping plate 52 and the second clamping plate 54 are arranged opposite to each other and spaced apart in the height direction so that when the frame is placed on the roller 43, they can be respectively limited from the upper and lower sides of the frame.

[0051] The first clamping plate 52 includes a first connecting section 522 rotatably connected to the first cylinder 521, a second connecting section 523 rotatably connected to the mounting seat 51, and a first interfering section 524 for interfering with the limiting frame. The first cylinder 521 serves as a power source, and drives the first connecting section 522 to rotate through the telescopic movement of the output shaft, thereby driving the entire first clamping plate 52 to rotate. The second connecting section 523 is rotatably connected to the mounting seat 51, providing a stable rotation fulcrum for the first clamping plate 52. When the first clamping plate 52 is rotated to the appropriate position, the first interfering section 524 interferes with an end face of the frame. Driven by the first cylinder 521, the first clamping plate 52 can be flexibly rotated to the desired position to achieve the upper limit of the frame in the height direction.

[0052] The second clamping plate 54 includes a third connecting section 542 rotatably connected to the second cylinder 541, a fourth connecting section 543 rotatably connected to the mounting base 51, and a second interfering section 544 for interfering with the limiting frame. The second cylinder 541 serves as a power source, driving the third connecting section 542 to rotate through the telescopic movement of the output shaft, thereby driving the entire second clamping plate 54 to rotate. The fourth connecting section 543 is rotatably connected to the mounting base 51, providing a stable rotation fulcrum for the second clamping plate 54. When the second clamping plate 54 is rotated to the appropriate position, the second interfering section 544 interferes with the other end face of the frame, thereby simultaneously limiting the frame in the height direction with the first clamping plate 52. Driven by the second cylinder 541, the second clamping plate 54 can be flexibly rotated to the desired position to limit the frame in the height direction.

[0053] The first clamping plate 52 and the second clamping plate 54 are driven by their respective cylinders and can be independently rotated to the desired position. When the frame is placed on the roller 43, the first contact section 524 and the second contact section 544 respectively contact the upper and lower end surfaces of the frame, thereby limiting the frame in the height direction. This design enables the clamping assembly 5 to flexibly adapt to frames of different sizes and shapes, thereby improving the versatility and practicality of the device. The clamping assembly 5 achieves stable limitation of the frame in the height direction through the coordinated action of the first clamping plate 52 and the second clamping plate 54. This limiting method not only improves the stability of the frame during the flipping process, but also reduces the risk of the frame falling off or being damaged during the flipping process. At the same time, due to the adoption of the cylinder drive method, the operation of the clamping assembly 5 is simpler and faster, thereby improving work efficiency.

[0054] In some optional embodiments, such as Figure 10 As shown, the clamping assembly 5 also includes a contact plate 53 slidably connected to the mounting seat 51, and one end of the contact plate 53 is provided with a third cylinder 531 that drives the contact plate 53 to move in the horizontal direction. The contact plate 53 is a plate-like structure designed to provide additional limiting support on the side of the frame. The contact plate 53 is connected to the mounting seat 51 through a sliding mechanism. In actual use, a slide rail using common technical means can be used as a sliding mechanism, so that the contact plate 53 can move in the horizontal direction. When the frame is placed on the roller 43, the contact plate 53 can be moved to an appropriate position under the drive of the third cylinder 531, and contact the side of the frame, thereby limiting the frame in the horizontal direction. This design helps to prevent the frame from moving or offsetting in the horizontal direction during the flipping process.

[0055] The third cylinder 531 is a pneumatic actuator that drives the contact plate 53 to move through the telescopic movement of its output shaft. The output shaft of the third cylinder 531 is connected to one end of the contact plate 53. When the piston rod of the cylinder extends or retracts, it drives the contact plate 53 to move horizontally. The third cylinder 531 provides the necessary power source for the contact plate 53, allowing the contact plate 53 to flexibly move to the desired position, thereby limiting the horizontal position of the vehicle frame. This design improves the flexibility and adaptability of the clamping assembly 5, enabling it to handle frames of different sizes and shapes.

[0056] The arrangement of the contact plate 53 and the third cylinder 531 adds a horizontal limiting function to the clamping assembly 5 on top of the original vertical limiting function. The contact plate 53 is connected to the mounting base 51 via a sliding connection, ensuring its stable horizontal movement; and the third cylinder 531 acts as a power source, providing the necessary driving force for the movement of the contact plate 53. When the frame is placed on the roller 43, the first clamping plate 52 and the second clamping plate 54, driven by their respective cylinders, limit the upper and lower end faces of the frame; at the same time, the contact plate 53, driven by the third cylinder 531, limits the side faces of the frame. This three-dimensional limiting method greatly improves the stability and safety of the frame during the flipping process.

[0057] In some optional embodiments, such as Figure 1 and Figure 4As shown, the gantry assembly 2 further includes a track 1, which is disposed at the bottom of the gantry assembly 2 and is slidably connected to the track 1. In actual use, the track 1 includes a gantry track body 11, which is two long tracks 1 installed on the ground and serves as a guide; a track leveling plate 12, which is used to fix the track 1 on the flat ground and can adjust the straightness of the track 1; a gantry transmission rack 13, which is a rack 44 installed on the side of the gantry travel track 1, allowing the gantry to move forward and backward along the rack 44; and a limit rod 14, which is a limit contact device installed at both ends of the gantry track body 11.

[0058] The gantry track body 11 consists of two long rails 1 mounted on the ground. They are typically made of high-strength, corrosion-resistant materials such as steel or alloys. The gantry track body 11 provides a sliding track 1 for the gantry assembly 2. The bottom of the gantry assembly 2 slides onto the track 1, ensuring smooth movement of the gantry along the track 1. The gantry track body 11 also serves as a guide, ensuring that the gantry assembly 2 maintains a straight line during movement and avoids deviation from the intended path.

[0059] The track-leveling plate 12 is a fixture used to securely fasten the track 1 to the ground. Installed beneath the track 1, it is connected to the ground and track 1 via bolts or other fastening devices. The plate's design allows for a certain degree of adjustment in the height and straightness of the track 1 to ensure its flatness and linearity. The plate not only secures the track 1 to the ground, preventing it from moving or deforming, but also ensures its straightness and levelness through adjustment, thereby improving the stability and precision of the movement of the gantry assembly 2.

[0060] The gantry transmission rack 13 is a rack 44 installed on the side of the gantry walking track 1. The gantry transmission rack 13 and the transmission mechanism in the gantry assembly 2 are introduced below. The transmission mechanism is specifically the gantry drive gear 24, which cooperates with it. When the gantry assembly 2 moves, the transmission mechanism, that is, the gantry drive gear 24 engages with the rack 44, thereby realizing smooth movement of the gantry.

[0061] The gantry drive rack 13 provides precise driving force and positioning capability for the movement of the gantry assembly 2. By engaging with the transmission mechanism, the rack 44 can ensure that the gantry maintains a constant speed and position accuracy during movement, thereby improving the stability and reliability of the entire system.

[0062] Limit rods 14 are contact devices installed at both ends of the gantry track body 11. Installed at both ends of the track 1, when the gantry assembly 2 reaches the end of the track 1, it contacts the limit rods 14, thereby limiting the gantry's range of movement. Limit rods 14 provide safety protection, preventing the gantry assembly 2 from moving beyond the intended range and causing damage or accidents. They also serve as endpoint markers for the gantry assembly 2's movement, helping operators accurately determine the gantry's position.

[0063] The various components of the track 1 system work closely together to ensure the smooth and precise movement of the gantry assembly 2 on the track 1. The gantry track body 11 provides the gantry with a sliding track 1; the track leveling plate 12 ensures the flatness and linearity of the track 1; the gantry drive rack 13 provides precise driving force and positioning for gantry movement; and the limit rod 14 provides safety protection, preventing the gantry from exceeding the predetermined range. The coordinated operation of these components enables the gantry assembly 2 to achieve smooth, precise, and safe movement on the track 1, meeting the needs of various application scenarios.

[0064] In actual use, such as Figures 1 to 5 As shown, the gantry assembly 2 is provided with a gantry travel motor 23, which is a drive motor 47 installed under the longitudinal beam 21 for driving the movement of the gantry; the gantry drive gear 24: a gear installed on the output shaft of the gantry travel motor 23, and meshing with the gantry transmission rack 13, for driving the gantry to move; the gantry travel guide wheel 25, which is a roller installed under the gantry, can roll along the gantry track body 11 to assist in movement; the flip support seat 26, which is a plurality of flip support seats 26 installed on the inner side of the longitudinal beam 21; the flip positioning roller 27, which is a flip roller installed on the flip support, is used to assist the rotation of the flip mechanism and assist in flipping and positioning; the anti-collision alarm device 29: a limit block installed at both ends of the gantry. When the gantry touches the limit rod 14, an alarm is issued and the movement of the gantry is automatically stopped; the distribution box 210: a motor servo driver installed on the gantry, which can achieve high-precision control and positioning of the clamping mechanism mechanical arm.

[0065] In actual use, the gantry travel motor 23 is installed below the longitudinal beam 21 and serves as the power source for driving the gantry. It drives the gantry on the track 1 through the rotation of its output shaft, achieving position adjustment of the frame flipping mechanism. The gantry drive gear 24 is mounted on the output shaft of the gantry travel motor 23 and meshes with the gantry transmission rack 13. It can transmit the rotational power of the gantry travel motor 23 to the gantry transmission rack 13, thereby driving the gantry along the track 1. The gantry travel guide wheel 25 is installed below the gantry, contacting and rolling on the gantry track body 11. It provides guidance and support during gantry movement, ensuring that the gantry can move smoothly and accurately along the track 1. The flip support seat 26 is installed on the inner side of the longitudinal beam 21 and serves as the support structure for the flip mechanism. It provides the necessary support and stability when the flip mechanism is operating, ensuring the safety and reliability of the flipping process. The flip positioning roller 27 is mounted on the flip support seat 26 and contacts the roller 43 or related components of the flip mechanism body 4 to ensure a smooth and accurate flipping process. At the same time, it also plays a positioning role to prevent the flipping mechanism from shifting during the rotation process. The anti-collision alarm device 29 is installed at both ends of the gantry and used as a limit block. When the gantry moves to the end of the track 1 or contacts other obstacles, such as the limit rod 14, the anti-collision alarm device 29 will send an alarm signal and automatically stop the movement of the gantry, thereby preventing the occurrence of collision accidents. The distribution box 210 is installed on the gantry as the installation location of the motor servo driver. The motor servo driver in the distribution box 210 can receive control signals and accurately control the movement of the robotic arm to achieve high-precision operation of the frame flipping mechanism.

[0066] In some optional embodiments, such as Figure 1 and Figure 2 As shown, multiple gantry assemblies 2 are spaced along the length of the track 1. A stopper assembly for limiting the position of the flip mechanism 4 is fixed to the longitudinal beam 21. The stopper assembly includes a first roller 28 rotatably connected to the outer circumference of a roller 43. Multiple gantry assemblies 2 are spaced along the length of the track 1. Each gantry assembly 2 has an independent structure and function, capable of supporting and moving the flip mechanism 4. The track 1 provides a sliding path for the gantry assemblies 2, ensuring smooth movement along the intended direction.

[0067] The flip mechanism body 4 is the main body that needs to be moved and flipped, and includes components such as a frame and rollers 43 supporting the frame. A position limiting assembly is fixed to the longitudinal beam 21 of the gantry assembly 2 and is used to limit the position of the flip mechanism body 4 to prevent it from shifting or shaking during movement. The first roller 28, which is rotatably connected to the outer circumference of the roller 43, is a key component of the position limiting assembly. When the flip mechanism body 4 moves on the gantry assembly 2, the first roller 28 contacts the outer circumference of the roller 43, limiting the movement trajectory of the flip mechanism body 4 through rolling friction, ensuring that it moves along the predetermined path.

[0068] The gantry assembly 2 moves along the track 1. The flipping mechanism body 4 contacts the longitudinal beam 21 or other supporting structure of the gantry assembly 2 through the roller 43 at its bottom to achieve smooth rotation. The first roller 28 of the limiting assembly is rotatably connected to the outer circle of the roller 43, forming a rolling friction limiting method. When the flipping mechanism body 4 moves, the first roller 28 rolls with the roller 43, but due to its contact with the outer circle of the roller 43, the deviation and shaking of the flipping mechanism body 4 are limited. The first roller 28 of the limiting assembly not only limits the moving trajectory of the flipping mechanism body 4, but also reduces the frictional resistance during the movement through rolling friction, thereby improving the operating efficiency and stability of the system. This design enables the entire flipping system to efficiently and accurately complete the flipping operation of the frame, meeting the needs of various application scenarios.

[0069] In some optional embodiments, such as Figure 1 and Figure 6 As shown, it also includes a lifting assembly 3, which is fixed to the gantry assembly 2 and is used to lift the frame. The lifting assembly 3 includes two frame trays 37 arranged opposite to each other and a lifting mechanism for driving the frame trays 37 to move in the height direction.

[0070] The lifting assembly 3 is fixed to the gantry assembly 2 and serves as the primary mechanism for lifting the vehicle frame. The frame tray 37 supports the vehicle frame, ensuring its stability and safety during the lifting process. The frame tray 37 contacts the ends of the vehicle frame, and its load-bearing area and strength prevent it from slipping or being damaged during the lifting process. The vehicle frame rests on two opposing frame trays 37, forming a stable support structure.

[0071] The frame tray 37 is connected to the lifting mechanism. When the lifting mechanism is activated, it drives the frame tray 37 to move in the vertical direction, thereby achieving the lifting and lowering of the frame. The lifting mechanism is fixed to the gantry assembly 2, which provides a stable support platform for the lifting mechanism, ensuring that it can smoothly and accurately drive the frame tray 37.

[0072] Lifting assembly 3, through the coordination of the frame tray 37 and the lifting mechanism, enables smooth lifting of the frame. When the frame needs to be flipped, lifting assembly 3 first raises the frame to a certain height, then gantry assembly 2 moves along track 1 to the flipping position, and finally the flipping mechanism performs the flipping operation. Throughout this process, lifting assembly 3 ensures the stability and safety of the frame during lifting and flipping, providing the necessary support for the frame flipping operation.

[0073] In some optional embodiments, such as Figure 1 and Figure 6 As shown, the lifting mechanism includes a chain 34 idler wheel 33 installed on the gantry assembly 2, and a chain 34 slidingly connected to the chain 34 idler wheel 33, one end of the chain 34 is fixed to the counterweight box 39, and the other end is fixed to the frame tray 37, and a lifting gear assembly 32 for driving the chain 34 to move and a lifting motor 31 connected to the lifting gear assembly 32 are provided on the gantry assembly 2.

[0074] The lifting motor 31 serves as a power source, providing the necessary torque to drive the entire lifting mechanism. The lifting gear assembly 32 is composed of a series of gears, which are used to convert the rotational motion of the lifting motor 31 into the movement of the chain 34. The chain 34 idler wheel 33 is installed on the gantry assembly 2 to support and guide the movement of the chain 34, ensuring that the chain 34 maintains the correct path and tension during movement. The chain 34 serves as a transmission medium, connecting the counterweight box 39 and the frame tray 37, and its movement realizes the lifting and lowering of the frame. The counterweight box 39 is used to balance the load on the chain 34, ensuring a smooth lifting process and reducing the burden on the motor. The frame tray 37 carries the frame and is connected to the lifting mechanism through the chain 34.

[0075] The lifting motor 31 is connected to the lifting gear assembly 32 via a drive shaft. When the motor is started, its rotational motion is converted into movement of the chain 34 via the gear assembly. This design allows the motor's rotation to be efficiently converted into the linear motion of the chain 34. The gears in the lifting gear assembly 32 mesh with the chain 34. When the gears rotate, the chain 34 moves along the gear teeth. This meshing relationship ensures that the chain 34 can move smoothly and continuously, thereby raising and lowering the frame. During movement, the chain 34 contacts the chain idler wheel 33, which supports and guides the chain 34. This idler wheel ensures that the chain 34 does not deviate from the predetermined path during movement and also helps maintain the tension of the chain 34, preventing it from slacking or becoming overly tight. One end of the chain 34 is fixed to the counterweight box 39, and the other end is fixed to the frame tray 37. When the chain 34 moves, it pulls the counterweight box 39 and the frame tray 37 at the same time, but due to the existence of the counterweight box 39, it can balance the load on the chain 34 to a certain extent, making the lifting process of the frame more stable.

[0076] The gantry assembly 2 serves as the supporting structure for the entire lifting mechanism. It secures components such as the chain 34, idler pulley 33, and hoisting gear assembly 32, providing a stable mounting platform for them. Furthermore, the gantry assembly 2, through its structural design and strength, ensures the stability and safety of the lifting mechanism when carrying a vehicle frame. Through the coordinated interaction of these components, the lifting mechanism smoothly lifts the vehicle frame tray 37 and the vehicle frame it carries. When the lifting motor 31 is activated, it rotates the hoisting gear assembly 32, which in turn drives the chain 34. The movement of the chain 34 causes the counterweight box 39 and the vehicle frame tray 37 to rise or fall simultaneously, thereby completing the lifting and flipping preparations for the vehicle frame. Throughout the entire process, the idler pulley 33 of the chain 34 ensures the correct path and tension of the chain 34, while the counterweight box 39 balances the load on the chain 34, making the lifting process smoother and more efficient. This design not only improves the efficiency and safety of the vehicle frame flipping operation, but also reduces the burden on the motor and energy consumption.

[0077] In actual use, the lifting mechanism also includes a lifting support base 35, which is the lifting mechanism frame mounted on the longitudinal beam 21; a lifting guide rail 36, which is a track 1 mounted on the lifting support base 35 and serves as a guide; an electric cylinder mounted at the rear of the frame tray 37, which allows horizontal width adjustment to accommodate vehicles of different widths and layouts, preventing interference between the frame or components and the tray; and a lifting boom 38, which is a retractable mechanical arm mounted at each end of the frame tray 37 and supports the frame wing. The lifting support base 35 is mounted on the longitudinal beam 21 and serves as the supporting structure of the lifting mechanism frame, providing a stable support base for the lifting mechanism and ensuring stability and safety during the lifting process. The lifting guide rail 36 is mounted on the lifting support base 35 and serves as the guide track 1 for the frame tray 37. It provides precise guidance for the lifting and lowering movement of the frame tray 37, ensuring that the tray moves smoothly along the predetermined trajectory during the lifting process. The frame tray 37, which supports the frame, is equipped with an electric cylinder at the rear for width adjustment. The horizontal width of the frame tray 37 is adjusted by adjusting the rear electric cylinder based on the width and layout of the vehicle frame, accommodating vehicles of varying widths and layouts. This prevents interference between the vehicle frame or components and the tray, ensuring a stable and secure placement of the vehicle frame on the tray. The electric cylinder, mounted at the rear of the frame tray 37, serves as the width adjustment actuator. It can adjust the horizontal width of the frame tray 37 through telescopic movement to accommodate vehicles of varying widths and layouts. The electric cylinder offers precise control, rapid response, and stability and reliability, meeting the requirements for width adjustment of the frame tray 37. Lifting arms 38, mounted at both ends of the frame tray 37, act as retractable mechanical arms. During the raising and lowering of the frame tray 37, the lifting arms 38 support the frame's wings, providing additional support. This ensures the stability of the frame during the raising and lowering process, preventing tilting or damage due to loss of support. Furthermore, the retractability of the lifting arms 38 allows it to accommodate vehicles of varying heights and widths, enhancing the versatility and flexibility of the lifting mechanism.

[0078] In some optional embodiments, such as Figure 8 and Figure 9 As shown, a support assembly for supporting the position-limiting flipping mechanism body 4 is fixed on the gantry assembly 2 , and the support assembly includes a fixing frame 41 fixed to the beam 22 , and a second roller 42 rotatably connected to the inner circle of the roller 43 .

[0079] The support assembly is fixed to the crossbeam 22 of the gantry assembly 2 and is used to support and limit the position of the flip mechanism body 4. A fixed frame 41 is fixed to the crossbeam 22 and serves as the foundation of the support assembly, providing a mounting location for the second roller 42. The second roller 42 is rotatably connected to the inner circumference of the roller 43 and cooperates with the fixed frame 41 to support and limit the position of the flip mechanism body 4.

[0080] The fixing frame 41 is secured to the crossbeam 22 via bolts, welding, or other fastening methods, ensuring the stability and reliability of the support assembly. As one of the primary structures of the gantry assembly 2, the crossbeam 22 provides solid support for the fixing frame 41. The second roller 42 is rotatably connected to the inner circumference of the roller 43. This design allows the second roller 42 to roll along with the rotation of the roller 43 during the movement of the flip mechanism 4, reducing frictional resistance and improving movement efficiency. Furthermore, the coordination of the second roller 42 with the fixing frame 41 limits the vertical movement of the flip mechanism 4, ensuring its stability during the flipping process.

[0081] The support assembly provides necessary support and position limiting for the flip mechanism body 4 through the fixing frame 41 and the second roller 42. During the flipping process, the support assembly ensures that the flip mechanism body 4 will not fall out of control due to gravity, and also prevents it from excessive displacement in the horizontal direction.

[0082] The provision of the support assembly provides more stable and reliable support for the flipping mechanism body 4 during the flipping process. Through the cooperation of the fixing frame 41 and the second roller 42, the support assembly limits the vertical and horizontal movement of the flipping mechanism body 4. Furthermore, the first roller 28 of the limiting assembly is rotatably connected to the outer circumference of the roller 43, forming a rolling friction limiting method. The first roller 28 and the second roller 42 jointly limit the flipping mechanism body 4, ensuring its stability and safety during the flipping process. This design not only improves the efficiency of the flipping operation, but also reduces the risk of wear and damage to the flipping mechanism body 4. Furthermore, the support assembly has a simple structure and is easy to install and maintain, providing a strong guarantee for the operation of the entire system.

[0083] In summary, the embodiment of the present application provides a frame flipping mechanism, including a gantry assembly 2, a flipping mechanism body 4 and a clamping assembly 5, the gantry assembly 2 includes longitudinal beams 21 on both sides and a cross beam 22 fixed between the two longitudinal beams 21; the flipping mechanism body 4 is fixed to the gantry assembly 2, and is used to drive the frame to flip, which includes a hollow roller 43 with a side opening, and a flipping assembly for driving the roller 43 to rotate; the clamping assembly 5 includes a mounting seat 51 fixed to the roller 43, and a clamping member rotatably connected to the mounting seat 51, for limiting the height direction of the frame.

[0084] In actual use, the gantry assembly 2 includes longitudinal beams 21 on both sides and a crossbeam 22 fixed between the two longitudinal beams 21, which constitute the main support structure of the entire flipping mechanism. The gantry assembly 2 provides a stable support structure for the entire device. The fixed connection between the longitudinal beams 21 and the crossbeam 22 ensures the stability of the device, allowing the flipping mechanism body 4 and the clamping assembly 5 to be safely installed and operate. The flipping mechanism body 4 includes a hollow roller 43 with a side opening and a flipping assembly for driving the roller 43 to rotate. The flipping mechanism body 4 is fixed to the gantry assembly 2. The hollow design and side opening of the roller 43 allow the frame to be easily put in and out, which is convenient for improving the flipping efficiency. At the same time, the flipping assembly can drive the roller 43 to rotate, thereby driving the frame to flip. The flipping mechanism body 4 is the main component that drives the frame to flip. Through the rotation of the roller 43, the frame can be safely and smoothly flipped to the desired angle, which is convenient for subsequent processing or inspection. The clamping assembly 5 includes a mounting seat 51 fixed to the roller 43 and a clamping member rotatably connected to the mounting seat 51. The clamping assembly 5 is fixed to the roller 43 through the mounting seat 51, and the clamping member is rotatably connected to the mounting seat 51. When the frame is placed in the roller 43, the clamping member can be rotated to an appropriate position and limit the frame in the height direction to prevent it from moving or slipping during the flipping process. The clamping assembly 5 ensures the stability and safety of the frame during the flipping process. Through the limiting action of the clamping member, the frame is firmly fixed to the roller 43 and can maintain a stable state even during the flipping process. The flipping mechanism of the present application can improve the flipping efficiency while meeting the safety of the frame during flipping.

[0085] In actual use, in order to realize the automatic flipping of the frame, a complete flipping machine control system can be used. The system is mainly divided into three modules: information storage module, information reading module and execution module.

[0086] First, the information storage module is responsible for analyzing and calculating the frame positioning and clamping coordinates corresponding to different vehicle models, including the moving position coordinates of the gantry assembly 2, the number of action groups required for the electric cylinder and the air cylinder clamping, the cylinder clamping position information, the lifting mechanism lifting and lateral movement position coordinates, etc., and storing them in the storage program of the flip machine main control box after analysis and calculation.

[0087] Next, the information reading module uses a barcode scanner to obtain the model information of the vehicle frame to be clamped and its position on the AGV. It converts this information into electronic signals and sends them to the PLC in the main control box of the flip mechanism for data processing and logical operations. Based on this information, the PLC compiles operating instructions for the gantry assembly 2, the flip mechanism body 4, the clamping assembly 5, and the lifting assembly 3.

[0088] Finally, the execution module outputs signals through the remote IO module according to the operating instructions compiled by the PLC, controlling the movement of the gantry, the lifting and lowering of the lifting component 3, the extension and retraction of the clamping component 5, and the flipping of the flipping mechanism body 4, thereby achieving the frame clamping and flipping of the corresponding vehicle model.

[0089] When the transport AGV carrying the vehicle frame arrives at the flipping area, the barcode scanner scans the frame code to identify the incoming vehicle model. The PLC in the flip machine's main control box then outputs control signals through the remote IO module based on pre-calculated and compiled instructions for the corresponding vehicle model, automatically adjusting the positioning unit on the flip machine. The specific flipping actions are as follows:

[0090] In practice, the flipping mechanisms of the present application may be provided in plurality at intervals. In this embodiment, two flipping mechanisms are provided.

[0091] When in use, the two flipping mechanisms move to the designated coordinate positions along the length direction of the track 1;

[0092] The frame tray 37 is extended to a designated position along the width of the track 1. The lifting assembly 3 then descends to a designated height and extends the lifting boom 38 to lift the lower surface of the frame. The lifting assembly 3 then raises the frame to a designated tipping height, freeing it from the transport AGV.

[0093] The first clamping plate 52, the second clamping plate 54 and the contact plate 53 of the clamping assembly 5 are extended to the designated positions to clamp the lower wing surface, the side surface and the upper wing surface of the frame, and the flipping mechanism body 4 is controlled to rotate 180 degrees to realize the flipping of the frame;

[0094] After the vehicle frame is flipped over into position, the first clamping plate 52, the second clamping plate 54 and the contact plate 53 of the clamping assembly 5 return to their original positions, and the lower wing surface, the side surface and the upper wing surface of the vehicle frame are released.

[0095] The lifting assembly 3 lowers the vehicle frame onto the transport AGV and retracts the lifting boom 38 to its original position. Finally, the lifting assembly 3 rises to its original height, waiting for the next lift and flip of the vehicle frame. At the same time, the flip mechanism body 4 rotates 180° again to return to its original position.

[0096] The transport AGV moves after receiving the forward command, and the flipping mechanism waits for the next frame to flip.

[0097] The entire flipping process is automatically controlled, which improves production efficiency and flipping accuracy.
