[0002] Automobile wheel hubs usually need to be heat treated during the processing, and the wheel hubs are often placed in a material frame so that a large number of wheel hubs can be processed and transported at the same time. The existing publication number CN212267539U discloses a wheel hub logistics transfer rack, which places the wheel hub on the main frame, limits the wheel hub by a limit device, and sets rollers at the bottom of the main frame to facilitate the movement of the main frame. However, the existing main frame is not equipped with a power device, the main frame cannot move autonomously, and the degree of automation of the transported products is low; at the same time, the main frame is prone to deformation when transporting heavier products for a long time, so that the products cannot be transported safely and reliably.

In the initial state, the material frame is first transported to the roller conveyor at the entrance of the feeding station by the material frame conveyor, and then the material frame enters the feeding station for heat treatment; after the hub processing in the material frame is completed, the material frame is transported from the roller conveyor at the entrance of the discharging station to the material frame conveyor. In this way, the material frame can flow between the feeding station, the discharging station and the material frame conveyor.

[0007] Preferably, the first roller and the material frame conveyor are rotatably connected, and the first reduction motor is installed on the material frame conveyor; a sprocket is provided on the reducer output shaft of the first reduction motor, and a sprocket is provided on the first roller; the sprocket on the first reduction motor and the sprocket on the first roller are connected by a chain, and the first roller rotates relative to the material frame conveyor when the first reduction motor is working; a plurality of roller assemblies rotatably connected to the material frame conveyor are provided at the bottom of the material frame conveyor, and the roller assembly includes a roller shaft and a roller body; both ends of the roller shaft are rotatably connected to the material frame conveyor through bearings, and both ends of the roller shaft are provided with roller bodies that rotate synchronously with the roller bodies, and the roller bodies are arranged in close contact with the mainstream rotating track; a third reduction motor is also provided at the bottom of the material frame conveyor, a sprocket is provided on the reducer output shaft of the third reduction motor, and a sprocket is provided on the roller shaft; the sprocket on the third reduction motor and the sprocket on the roller shaft are connected by a chain, and when the third reduction motor rotates, the roller assembly is driven to rotate relative to the material frame conveyor; the moving direction of the material frame conveyor and the direction of the first roller conveyor to convey products are arranged perpendicular to each other.

[0008] Preferably, a first positioning assembly and a second positioning assembly which are arranged perpendicularly to each other are provided at the end of the main flow track, and the first positioning assembly faces the direction of the first roller conveyor to transfer the product; the first positioning assembly includes a first bracket, a first cylinder and a first top plate, and the first cylinder is fixedly mounted on the first bracket; a first top plate is provided on the piston shaft of the first cylinder, and a plurality of limit members are provided on the first top plate, and the outer contour of the limit members matches the outer contour of the first roller; the second positioning assembly includes a second bracket, a second cylinder and a second top plate, and the second cylinder is fixedly mounted on the second bracket, and a second top plate is provided on the piston shaft of the second cylinder, and the second top plate and the first roller are arranged perpendicularly to each other.

[0009] When the first reduction motor is working, it drives the first roller to rotate relative to the material frame conveyor through the chain. The rotation direction of the first roller is set toward the flipping device, which is convenient for transporting the material frame from the material frame conveyor to the flipping device. A roller assembly is provided at the bottom of the material frame conveyor. When the third reduction motor is working, it drives the roller assembly to rotate relative to the material frame conveyor through the chain. The roller assembly is fitted with the main flow track, so that the material frame conveyor can move along the main flow track as a whole, which is convenient for the material frame to automatically flow between the multi-axis manipulator assembly and the feeding station. The first positioning assembly and the second positioning assembly cooperate with each other to automatically align the two end faces of the material frame, and the outer contour of the limiter matches the outer contour of the first roller, so that the positioning effect is better.

[0011] The multi-axis robot clamps the wheel hub in the material frame, which makes it easy to load and unload the wheel hub. When the multi-axis robot takes out the wheel hub from the material frame, the wheel hub will shift relative to the material frame during the heat treatment process or the transfer process. The visual camera will take a picture of the position of the wheel hub when the clamping device is working. If the wheel hub is within the working range of the multi-axis robot, the multi-axis robot controls the clamping device to take the wheel hub out of the material frame. If the wheel hub shifts a lot relative to the material frame, the multi-axis robot cannot reach into the material frame to clamp the wheel hub. At this time, the control component will send a stop working instruction to the multi-axis manipulator component, and the control component will automatically alarm, so that the manual operator will handle it. By manually re-adjusting the position of the wheel hub, the multi-axis manipulator component can start working again.

[0012] Preferably, the flipping device includes a main frame, a lifting cylinder is provided at the bottom of the main frame, a roller lifting assembly is provided inside the main frame and is slidably connected to the main frame, and the roller lifting assembly is installed on the lifting cylinder; a main driving rotating device and a driven rotating device are respectively provided on the left and right sides of the main frame, and the main driving rotating device and the driven rotating device control the rotation of the material frame relative to the main frame when working synchronously.

[0014] Preferably, the main driving rotating device comprises a first sliding seat, a third cylinder, a first rotating shaft and a fifth reduction motor; the first sliding seat is slidably connected to the main frame, the third cylinder is fixedly connected to the main frame, and the piston shaft of the third cylinder is connected to the first sliding seat; a first rotating shaft rotatably connected to the first sliding seat is provided in the first sliding seat, and a fifth reduction motor is provided on the top of the first sliding seat; a transmission member connecting the first rotating shaft and the fifth reduction motor is provided between the two, and when the fifth reduction motor is working, the first rotating shaft rotates relative to the first sliding seat; a first rotating frame fixedly connected to the first rotating shaft is provided at the end of the first rotating shaft, and the first rotating frame is arranged parallel to the side of the main frame; the driven rotating device comprises a second sliding seat, a fourth cylinder and a second rotating shaft, and the second sliding seat is slidably connected to the main frame; the fourth cylinder is fixedly connected to the main frame, and the piston shaft of the fourth cylinder is connected to the second sliding seat; a second rotating shaft rotatably connected to the second sliding seat is provided in the second sliding seat, and a second rotating frame fixedly connected to the second rotating shaft is provided on the second rotating shaft, and the first rotating frame and the second rotating frame are arranged parallel to each other.

[0015] In the default state, the lifting cylinder controls the roller lifting assembly to be flush with the material frame conveyor, so that the first reduction motor drives the first roller to rotate, and the material frame will be transferred from the material frame conveyor to the support frame of the roller lifting assembly; when the material frame is on the roller lifting assembly, the third cylinder on the main drive rotating device controls the first sliding seat to approach the material frame, so that the first rotating frame will fit the side of the material frame; at the same time, the fourth cylinder on the driven rotating device works to control the second sliding seat to approach the material frame, so that the second rotating frame will fit the side of the material frame. At this time, the material frame is clamped between the first rotating frame and the second rotating frame; then the lifting cylinder controls the roller lifting assembly to descend, so as to make way for the rotation of the material frame to avoid interference between the material frame and the support frame. Then the fifth reduction motor on the main drive rotating device works to drive the first rotating shaft to rotate relative to the first sliding seat, so that the first rotating frame and the second rotating frame will drive the material frame to rotate 180 degrees relative to the main frame; after the material frame rotates and stands upside down, placing a wheel hub on the material frame will not cause excessive deformation of the material frame. The lifting cylinder controls the roller lifting assembly to rise, so that the bottom of the material frame is placed on the turning roller of the support frame. Since the guide rollers are set on the corners of the support frame, the support frame can only be lifted in the vertical direction, and the lifting accuracy is higher. The lifting position of the support frame is controlled by the first contact switch to avoid collision between the support frame and the material frame. Then the third cylinder and the fourth cylinder will shrink, so that the first rotating frame and the second rotating frame are away from the material frame; finally, the fourth reduction motor starts to work, and the fourth reduction motor drives the turning roller to rotate relative to the support frame through the chain, so that the material frame can be transferred from the turning device to the material frame conveyor.

[0016] Preferably, a plurality of angle contacts are provided at the end of the first rotating shaft, and a plurality of second contact switches fixedly connected to the first sliding seat are provided, and each of the second contact switches is paired with an angle contact arranged adjacent to it; when the first rotating shaft drives the angle contact to rotate, the angle contact contacts the second contact switch.

[0017] The second contact switch and the angle contact member cooperate with each other to limit the rotation angle of the first rotating shaft, so that the first rotating shaft can reliably control the material frame to flip 180 degrees.

[0018] Preferably, a limit cylinder is provided on the second sliding seat, and a limit rod is provided on the piston shaft of the limit cylinder; a limit hole is provided on the second rotating frame, and the limit hole and the limit rod are aligned when the second rotating frame is in a vertical upright state; the second sliding seat is also provided with a proximity switch, and a detection hole is provided on the second rotating frame; the detection hole and the limit hole are arranged at the same horizontal height; when the second rotating frame is in a vertical upright state, the detection hole and the proximity switch are arranged coaxially.

[0019] In the default state, the second rotating frame is in a vertical upright state; the limiting cylinder drives the limiting rod to extend into the limiting hole, thereby ensuring that the second rotating frame is in a vertical upright state, thereby calibrating the rotation position of the second rotating frame. The proximity switch cooperates with the detection hole position to detect the rotation position of the second rotating frame; when the proximity switch is aligned with the detection hole position, the proximity switch can generate an electrical signal, which indicates that the second rotating frame has automatically reset to the default initial state; when the proximity switch is misaligned with the detection hole position, the proximity switch will not generate an electrical signal, which indicates that the second rotating frame has not reset to the default initial state.

[0020] Compared with the prior art, the present invention has the following beneficial effects: 1. The material frame conveyor on the main rotating track facilitates the material frame to automatically flow between the feeding station, the discharging station and the flipping device; 2. The multi-axis manipulator assembly is provided to facilitate the accurate clamping of the wheel hub in the material frame, and facilitate the loading and unloading of the wheel hub. 3.

[0026] The specific operation process of this embodiment is as follows: in the initial state, the material frame is on the material frame conveyor trolley 6, and the material frame conveyor trolley 6 is at the end of the main rotating track 1. At this time, the multi-axis manipulator assembly 9 clamps the wheel hub and places it in the material frame; then the third reduction motor 64 drives the roller assembly 63 to rotate, so that the material frame conveyor trolley 6 moves along the main rotating track 1 to the feeding station 2; when the material frame conveyor trolley 6 is aligned with the feeding station 2, the first reduction motor 61 works to drive the first roller 62 to rotate relative to the material frame conveyor trolley 6, so that the material frame will be transferred to the roller conveyor 5 at the door of the feeding station 2; then the roller conveyor 5 works to transport the material frame to the feeding station 2. Processing is performed inside station 2; after the wheel hub in the material frame is processed, it is sent out from the unloading station 3, and the roller conveyor 5 at the door of the unloading station 3 works to transfer the material frame back to the material frame conveyor trolley 6; then the material frame conveyor trolley 6 brings the material frame back to the initial position, and then the multi-axis manipulator assembly 9 works to remove the processed wheel hub from the material frame; then the material frame is in an unloaded state, and the material frame conveyor trolley 6 drives the material frame to be transported to the turning device 4; the material frame is rotated 180 degrees through the turning device 4 and then returns to the material frame conveyor trolley 6; then the material frame conveyor trolley 6 brings the material frame back to the initial position for loading, and then the above steps are repeated to process the wheel hub.

[0027] The specific working principle of the flip device 4 is as follows: in the default state, the lifting cylinder 42 controls the roller lifting assembly 43 to be flush with the material frame conveyor 6, so that the first reduction motor 61 drives the first roller 62 to rotate, and the material frame will be transferred from the material frame conveyor 6 to the support frame 431 of the roller lifting assembly 43; when the material frame is on the roller lifting assembly 43, the third cylinder 442 on the main driving rotating device 44 controls the first sliding seat 441 to approach the material frame, so that the first rotating frame 446 will fit with the side of the material frame; at the same time, the fourth cylinder 452 on the driven rotating device 45 works to control the second sliding seat 451 to approach the material frame, so that the second rotating frame 454 will fit with the side of the material frame. At this time, the material frame is clamped between the first rotating frame 446 and the second rotating frame 454; then the lifting cylinder 42 controls the roller lifting assembly 43 to descend, so as to make way for the rotation of the material frame to avoid interference between the material frame and the support frame 431. Then the fifth reduction motor 444 on the main driving rotating device 44 drives the first rotating shaft 443 to rotate relative to the first sliding seat 441, so that the first rotating frame 446 and the second rotating frame 454 will drive the material frame to rotate 180 degrees relative to the main frame 41; after the material frame rotates and stands upside down, placing a wheel hub on the material frame will not cause excessive deformation of the material frame. Then the lifting cylinder 42 controls the roller lifting assembly 43 to rise, so that the bottom of the material frame is placed on the turning roller 433 of the support frame 431. Since the guide rollers 434 are set on the corners of the support frame 431, the support frame 431 can only be lifted and lowered in the vertical direction, and the lifting accuracy is higher. The lifting position of the support frame 431 is controlled by the first contact switch 10 to avoid collision between the support frame 431 and the material frame.
