[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 3As shown, an automobile wheel hub conveying device according to an embodiment of the present invention comprises three conveying seats 1, and two conveying seats 1 are arranged opposite to each other, and another conveying seat 1 is located at one end close to the two opposite conveying seats 1; a plurality of conveying rollers 11 are rotatably connected to the three conveying seats 1 through a chain group, and the plurality of conveying rollers 11 are arranged in two rows, and the height of the plurality of conveying rollers 11 near the loading position is higher than the height of the plurality of conveying rollers 11 near the unloading position; a number 1 side frame 12 and a number 2 side frame 13 are fixedly connected to both sides of the top surface of the conveying seat 1, and the corners of the number 1 side frame 12 and the number 2 side frame 13 are both arc-shaped; the outer wall of the number 1 side frame 12 is close to the A No. 1 arc pad 4 is fixedly connected near the corner, and the cross-section of the No. 1 arc pad 4 is an arc-shaped setting; a No. 2 arc pad 41 is fixedly connected to the outer wall of the No. 2 side frame 13 near the corner; a plurality of elastic members are fixedly connected to the interior of the No. 1 arc pad 4 and the No. 2 arc pad 41, and the No. 1 arc pad 4 and the No. 2 arc pad 41 are arranged opposite to each other; when conveying and packaging automobile wheels, since some areas are difficult to use a straight conveyor line due to the rigid influence of the environment, a curved conveyor line is used to convey the automobile wheels for sorting and packaging, and three conveying seats 1 are used to form the main frame of the sorting and packaging line, and each conveying seat 1 is rotatably connected to two rows of staggered conveying rollers 11, and multiple The conveying roller 11 is driven by an external motor and a chain group. The No. 1 side frame 12 and the No. 2 side frame 13 are fixed on both sides of the top surface of each conveying seat 1 as guides. When the automobile wheel hub is placed on the multiple conveying rollers 11 at the loading position of the front conveying seat 1, the multiple conveying rollers 11 are driven by the external motor to drive the chain group to convey the automobile wheel hub. The automobile wheel hub is conveyed at high speed in the guide line formed by the No. 1 side frame 12 and the No. 2 side frame 13. When the automobile wheel hub reaches the turning point of the conveying seat 1, the automobile wheel hub can turn in accordance with the arc angle of the No. 1 side frame 12 and the No. 2 side frame 13, and the automobile wheel hub squeezes the No. 1 arc pad 4 and the No. 2 arc pad 41 supported by multiple elastic parts. The first arc pad 4 and the second arc pad 41 can cooperate with the deformation of multiple elastic parts to buffer and guide the inertial force generated by the high-speed conveying of the automobile wheel hub, and convert the automobile wheel hub from longitudinal conveying to lateral conveying, and thus convey it to the intersection of the three conveying seats 1, and sort it according to the quality of the automobile wheel hub inspection. The two oppositely arranged conveying seats 1 are two conveying lines for sorting according to the inspection results. Qualified automobile wheel hubs are sent to one conveying seat 1 for conveying and packaging, and unqualified automobile wheel hubs are sent to the other conveying seat 1 for rework. By setting a curved conveying line that matches the diameter of the automobile wheel hub, the damage caused by the inertial force during high-speed conveying and cornering of the automobile wheel hub can be reduced; The elasticity of the rubber of the No. 1 arc pad 4 and the No. 2 arc pad 41 can effectively buffer the inertial impact of the wheel hub during cornering, preventing the wheel hub from hard collision with the metal guardrail and roller, reducing surface scratches, deformation and coating damage. The rubber shares the impact force of the wheel hub on the metal guardrail and roller, reducing mechanical wear during long-term operation and reducing maintenance frequency. Compared to direct metal contact, rubber can significantly reduce the noise and vibration generated by wheel collisions, improving the working environment and extending equipment life. Rubber can adapt to wheels of different diameters and weights through deformation, eliminating the need for frequent hardware configuration adjustments. At the same time, the No. 1 side frame 12 and the No. 2 side frame 13 are fixed on the top surface of the conveying seat 1, which can block the conveyed automobile wheel hub and limit the automobile wheel hub to be conveyed between the No. 1 side frame 12 and the No. 2 side frame 13. The high friction coefficient of the No. 1 arc pad 4 and the No. 2 arc pad 41 can reduce the risk of side slip of the wheel hub caused by centrifugal force, keep it stable when passing through the curve, and reduce the occurrence of dislocation and rushing out of the conveying line during high-speed conveying of the automobile wheel hub.

[0024] like Figures 1 to 4 As shown, the inner walls of the No. 1 side frame 12 and the No. 2 side frame 13 are fixed with multiple sliding frames 2; multiple rollers 21 are rotatably connected to the multiple sliding frames 2; the rollers 21 are made of rubber; when the automobile wheel hub is transported on a curve, multiple sliding frames 2 are fixed on the No. 1 side frame 12 and the No. 2 side frame 13, and the sliding frames 2 on the No. 1 side frame 12 and the No. 2 side frame 13 are symmetrically arranged in pairs, and each sliding frame 2 is equipped with multiple rollers 21 for rotation, and the automobile wheel hub is placed between the multiple rollers 21 from the loading position of the conveying seat 1. As the multiple conveying rollers 11 rotate to convey the automobile wheel hub, the multiple rollers 21 rotate in contact with the outer wall of the automobile wheel hub to assist in conveying, playing a role in guiding the conveying of the automobile wheel hub, and at the same time relying on the rubber rollers 21 to directly contact the outer wall of the automobile wheel hub, the wear caused by the contact between the No. 1 side frame 12 and the No. 2 side frame 13 during the conveying process of the automobile wheel hub can be reduced.

[0025] like Figures 1 to 3 As shown, a guide plate 3 is fixed at the corner of the conveying seat 1, and the top surface of the guide plate 3 is set as an inclined surface; a plurality of friction protrusions 31 are fixed on the inclined surface of the guide plate 3; when the automobile wheel hub is conveyed to the curve at high speed, the guide plate 3 is fixed on the last longitudinal conveying roller 11, and the inclined surface of the guide plate 3 can guide the automobile wheel hub, so that the automobile wheel hub falls smoothly onto the horizontal conveying roller 11 for turning conveying, and at the same time, a plurality of friction protrusions 31 are fixed on the inclined surface of the guide plate 3 to increase friction, so that the automobile wheel hub reduces the conveying speed due to friction when passing through the plurality of friction protrusions 31, thereby reducing the strong impact of the inertia force generated by excessive speed, and improving the cornering buffering effect of the automobile wheel hub.

[0026] like Figure 1As shown, one end of the two conveying seats 1 is fixedly connected to a fixing seat 14, and the two fixing seats 14 are arranged opposite to each other; an intercepting plate 15 is fixedly connected to the fixing seat 14, and a U-shaped groove is opened on the intercepting plate 15; a No. 1 rubber pad 16 is fixedly connected in the U-shaped groove of the intercepting plate 15; when the automobile wheel hub is conveyed for unloading and packaging, the automobile wheel hub is sorted to the qualified conveyor line, and as multiple conveying rollers 11 drive the automobile wheel hub to the unloading place of the conveying seat 1, the automobile wheel hub falls onto the fixing seat 14 and is blocked by the U-shaped groove of the intercepting plate 15. The impact is buffered on the No. 1 rubber pad 16, and the qualified automobile wheel hub can be clamped by a robot for packaging, which plays the role of buffering, positioning, picking up and packaging the automobile wheel hub unloading, reducing the impact damage caused by the unloading of the automobile wheel hub.

[0027] like Figures 1 to 3 As shown, the outer walls of the three conveying rollers 11 are sleeved with multiple rubber rings 5, and the multiple rubber rings 5 are located at the unloading place of the conveying seat 1; the outer walls of the six rollers 21 are fixed with multiple rubber protrusions 51, the six rollers 21 are arranged opposite to each other in pairs, and the multiple rubber protrusions 51 are located at the unloading place of the conveying seat 1; when the automobile wheel hub is conveyed to the unloading place of the conveying seat 1, since the speed of the conveying line is uniformly controlled, it is easy for the automobile wheel hub to generate a large inertia force when unloading due to the normal speed of other wheel hubs. The multiple rubber rings 5 are fixed on the three conveying rollers 11, and the multiple rubber protrusions 51 are fixed on the six rollers 21 at the unloading place of the conveying seat 1. The multiple rubber rings 5 cooperate with the rubber protrusions 51 to increase the friction of the automobile wheel hub to be unloaded at the unloading place of the conveying seat 1, slow down the unloading speed of the wheel hub through friction resistance, make the unloading of the automobile wheel hub smooth, avoid tipping and uneven stacking caused by rapid sliding, and improve the stability of subsequent shipping processes; The high friction coefficient of the rubber ring 5 and the rubber bump 51 can effectively reduce the sliding and position deviation of the wheel hub caused by inertia and vibration, ensuring accurate material cutting and avoiding the risk of collision and falling; The elasticity of the rubber ring 5 and the rubber bump 51 can absorb the impact force during unloading, reducing damage such as scratches and bumps on the hub surface and edge caused by rigid contact. Compared with the direct contact with the metal conveyor roller 11, the rubber friction can reduce the noise caused by the collision between the hub and the conveyor roller 11, thereby improving the working environment.

[0028] like Figure 1 and Figure 5As shown, one end of the three conveying seats 1 that are close to each other is fixed with a motor seat 6; a turntable 61 is fixed to the motor seat 6 through a servo motor; a fence plate 62 is fixed to the top of the turntable 61, and the fence plate 62 is provided with an opening; when sorting automobile wheel hubs, the automobile wheel hubs are quality inspected during the transportation process of the front conveying seat 1 until the automobile wheel hubs are transported to the unloading place of the conveying seat 1 and fall onto the turntable 61, and are blocked by the fence plate 62 to prevent them from falling off. The output end of the servo motor on the motor seat 6 controls the rotation direction according to the detection result, and the automobile wheel hubs on the turntable 61 correspond to the corresponding conveying line, and then the automobile wheel hubs are pushed by the robot arm from the opening of the fence plate 62 to another conveying seat 1 for transportation, thereby playing the role of sorting and conveying the automobile wheel hubs.

[0029] The interior of the fence plate 62 is fixedly connected to an electric cylinder 7, and the electric cylinder 7 is arranged opposite to the opening of the fence plate 62; the output end of the electric cylinder 7 is fixedly connected to a pushing plate 71; the outer wall of the pushing plate 71 is fixedly connected to a No. 2 rubber pad 72; when the automobile wheel hub falls onto the turntable 61 from the unloading position of the conveying seat 1, the pushing plate 71 is used to intercept the automobile wheel hub, and the No. 2 rubber pad 72 is used to cushion the falling automobile wheel hub. The No. 2 rubber pad 72 reduces direct metal contact and avoids scratches on the edge of the wheel hub and the paint surface. Then the servo motor drives the automobile wheel hub on the turntable 61 to rotate in the corresponding conveyor line. After the direction, the output end of the electric cylinder 7 drives the pushing plate 71 to push the automobile wheel hub. After the automobile wheel hub is pushed onto the conveyor line, the electric cylinder 7 is reset, which plays a role in sorting and transferring the automobile wheel hub.

[0030] The push plate 71 has a U-shaped cross section; both ends of the push plate 71 are provided with inclined surfaces; when the automobile wheel hub falls onto the turntable 61 from the unloading position of the conveying seat 1, the inclined surface of the push plate 71 can guide the automobile wheel hub to rush onto the turntable 61. The push plate 71 can fit the outer contour of the wheel hub through the U-shaped structure, naturally guiding the wheel hub into the predetermined position to avoid deflection and jamming. During interception, the sidewall of the pushing plate 71 can absorb the inertial impact of the wheel hub, preventing the wheel hub from rebounding and tipping over after collision; At the same time, the U-shaped pushing plate 71 does not require complex sensors and power devices, and can achieve reliable interception by relying on the physical structure, thereby reducing maintenance costs.

[0031] A friction plate 8 is fixedly connected to the turntable 61, and the friction plate 8 is located at the opening of the fence plate 62; a plurality of dots are fixedly connected to the friction plate 8; when the automobile wheel hub falls on the turntable 61, the automobile wheel hub is rubbed by the friction plate 8 with the plurality of dots, and the friction plate 8 is fixed at the opening of the fence plate 62 to contact the automobile wheel hub first, which can reduce the inertial force generated when the automobile wheel hub falls, play the role of buffering and sorting the automobile wheel hub, and at the same time can achieve a protective effect on the push plate 71.

[0032] like Figures 1 to 3 、 Figure 5 As shown, the height of the two conveying rollers 11 at the loading positions of the conveying seats 1 relative to each other is lower than the height of the conveying rollers 11 at the unloading position of the other conveying seat 1; the top surface height of the turntable 61 is higher than the height of the conveying rollers 11 at the loading positions of the two conveying seats 1 relative to each other, and the top surface height of the turntable 61 is lower than the height of the conveying rollers 11 at the unloading position of the other conveying seat 1; during the process of curved conveying and packaging of automobile wheel hubs, in order to ensure the stability of the conveying of automobile wheel hubs, the front conveying seat 1 is set to the highest point, and then the subsequent conveying seats 1 are set to have a height difference. After the automobile wheel hub is placed on the front conveying seat 1 for conveyance, it is conveyed from high to low to the rear end. When passing through the turntable 61 in the middle, the height of the top surface of the turntable 61 is lower than the height of the front end, but the height of the top surface of the turntable 61 is higher than the height of the rear end, thereby also achieving a height difference and improving the effect of high-speed curved conveying of automobile wheel hubs.

[0033] Working process: When conveying and packaging automobile wheels, it is difficult to use a straight conveyor line due to the rigid influence of the environment in some areas. Instead, a curved conveyor line is used to convey the automobile wheels for sorting and packaging. Three conveyor seats 1 are used to form the main frame of the sorting and packaging line. Each conveyor seat 1 is rotatably connected to two rows of staggered conveyor rollers 11. The multiple conveyor rollers 11 are driven by an external motor and a chain group. The top surface of each conveyor seat 1 is respectively fixed with a No. 1 side frame 12 and a No. 2 side frame 13 on both sides as a guide. When the automobile wheel is placed on the multiple conveyor rollers 11 at the loading position of the front conveyor seat 1, the multiple conveyor rollers 11 are driven by the external motor to drive the chain group to convey the automobile wheel. The wheel hub is conveyed at high speed in the guide line formed by the No. 1 side frame 12 and the No. 2 side frame 13. When the automobile wheel hub reaches the turning point of the conveying seat 1, the automobile wheel hub can turn in accordance with the arc angle of the No. 1 side frame 12 and the No. 2 side frame 13, and the automobile wheel hub squeezes the No. 1 arc pad 4 and the No. 2 arc pad 41 supported by multiple elastic parts. The No. 1 arc pad 4 and the No. 2 arc pad 41 can cooperate with the deformation of multiple elastic parts to buffer and guide the inertial force generated by the high-speed conveying of the automobile wheel hub, and convert the automobile wheel hub from longitudinal conveying to lateral conveying. In this way, it is conveyed to the intersection of the three conveying seats 1 and sorted according to the quality of the automobile wheel hub inspection. The two relatively arranged conveying seats 1 are two lines with inspection as the center. The conveyor line for sorting the test results, qualified automobile wheel hubs are sent to a conveyor seat 1 for transportation and packaging, and unqualified automobile wheel hubs are sent to another conveyor seat 1 for transportation and rework. By setting a curved conveyor line that matches the diameter of the automobile wheel hub, the damage caused by inertia force during high-speed transportation and cornering of the automobile wheel hub can be reduced; the elasticity of the rubber of the No. 1 curved pad 4 and the No. 2 curved pad 41 can effectively buffer the inertia impact of the wheel hub when turning, avoid hard collision between the wheel hub and the metal guardrail and roller, reduce surface scratches, deformation and coating damage, and the rubber shares the impact force of the wheel hub on the metal guardrail and roller, reducing mechanical wear in long-term operation and reducing maintenance frequency; Compared with direct metal contact, rubber can significantly reduce the noise and vibration caused by wheel hub collision, improve the working environment and extend the life of the equipment. Rubber can adapt to wheels of different diameters and weights through deformation, without the need for frequent adjustment of hardware configuration; at the same time, the No. 1 side frame 12 and the No. 2 side frame 13 are fixed to the top surface of the conveying seat 1, which can block the conveyed automobile wheel hub and limit the automobile wheel hub to be conveyed between the No. 1 side frame 12 and the No. 2 side frame 13. The high friction coefficient of the No. 1 arc pad 4 and the No. 2 arc pad 41 can reduce the risk of side slip of the wheel hub caused by centrifugal force, keep it stable when passing through curves, and reduce the occurrence of dislocation and rushing out of the conveyor line during high-speed conveying of the automobile wheel hub;When conveying the automobile wheel hub on a curve, a plurality of sliding frames 2 are fixed on the No. 1 side frame 12 and the No. 2 side frame 13. The sliding frames 2 on the No. 1 side frame 12 and the No. 2 side frame 13 are symmetrically arranged in pairs. A plurality of rollers 21 are equipped on each sliding frame 2 to rotate, and the automobile wheel hub is placed between the plurality of rollers 21 from the loading position of the conveying seat 1. As the plurality of conveying rollers 11 rotate to convey the automobile wheel hub, the plurality of rollers 21 rotate in contact with the outer wall of the automobile wheel hub to assist in conveying, thereby playing a role in guiding the conveying of the automobile wheel hub. At the same time, the rubber rollers 21 directly contact the outer wall of the automobile wheel hub, which can reduce the wear caused by the automobile wheel hub contacting the No. 1 side frame 12 and the No. 2 side frame 13 during the conveying process. When the automobile wheel hub is conveyed to the bend at high speed, the guide plate 3 is fixed to the last longitudinal conveying roller 11. The inclined surface of the guide plate 3 can guide the automobile wheel hub, so that the automobile wheel hub falls smoothly onto the transverse conveying roller 11 for turning conveyance. At the same time, multiple friction bumps 31 are fixed to the inclined surface of the guide plate 3 to increase friction. When the automobile wheel hub passes through the multiple friction bumps 31, the conveying speed is reduced by friction, thereby reducing the strong impact of the inertia force caused by excessive speed and improving the cornering buffer effect of the automobile wheel hub. When the automobile wheel hubs are transported for unloading and packaging, the automobile wheel hubs are sorted to the qualified conveyor line. As the multiple conveyor rollers 11 drive the automobile wheel hubs to the unloading position of the conveying seat 1, the automobile wheel hubs fall onto the fixing seat 14 and are blocked by the U-shaped groove of the intercepting plate 15. The impact is buffered on the No. 1 rubber pad 16. The qualified automobile wheel hubs are clamped by the manipulator for packaging, which plays the role of buffering, positioning, picking up and packaging the automobile wheel hubs, reducing the impact damage caused by the unloading of the automobile wheel hubs; When the automobile wheel hub is conveyed to the unloading place of the conveying seat 1, since the speed of the conveying line is uniformly controlled, it is easy for the automobile wheel hub to generate a large inertia force when unloading due to the normal speed of the other wheel hubs. A plurality of rubber rings 5 are fixed on the three conveying rollers 11, and a plurality of rubber protrusions 51 are fixed on the six rollers 21 at the unloading place of the conveying seat 1. The plurality of rubber rings 5 cooperate with the rubber protrusions 51 to increase the friction of the automobile wheel hub to be unloaded at the unloading place of the conveying seat 1, slow down the unloading speed of the wheel hub through friction resistance, make the unloading of the automobile wheel hub smooth, and avoid rapid sliding. The tipping and uneven stacking caused by the rubber ring 5 and the rubber bump 51 can improve the stability of subsequent shipping processes; the high friction coefficient of the rubber ring 5 and the rubber bump 51 can effectively reduce the sliding and position deviation of the wheel hub caused by inertia and vibration, ensuring accurate unloading and avoiding the risk of collision and falling; the elasticity of the rubber ring 5 and the rubber bump 51 can absorb the impact force during unloading, reducing the damage such as scratches and bumps on the wheel hub surface and edge caused by rigid contact. Compared with the direct contact of the metal conveyor roller 11, the rubber friction can reduce the noise of the collision between the wheel hub and the conveyor roller 11, thereby improving the working environment; When sorting automobile wheel hubs, the automobile wheel hubs are quality inspected during the transportation process of the front conveying seat 1 until the automobile wheel hubs are transported to the unloading place of the conveying seat 1 and fall onto the turntable 61, and are blocked by the fence plate 62 to prevent them from falling off. The output end of the servo motor on the motor seat 6 controls the rotation direction according to the detection result, and the automobile wheel hubs on the turntable 61 correspond to the corresponding conveyor line. Then, the automobile wheel hubs are pushed by the manipulator and transferred from the opening of the fence plate 62 to another conveying seat 1 for transportation, which plays the role of sorting and conveying the automobile wheel hubs; when the automobile wheel hubs fall onto the turntable 61 from the unloading place of the conveying seat 1, the pushing plate 71 is used to intercept the automobile wheel hubs, and the No. 2 rubber pad 72 is used to cushion the falling automobile wheel hubs. The No. 2 rubber pad 72 reduces direct contact between metals to avoid scratches on the wheel hub edge and paint surface. , then the servo motor drives the automobile wheel hub on the turntable 61 to rotate in the corresponding direction of the conveyor line, and the output end of the electric cylinder 7 drives the pushing plate 71 to push the automobile wheel hub. After the automobile wheel hub is pushed to the conveyor line, the electric cylinder 7 resets, playing the role of sorting and transferring the automobile wheel hub; when the automobile wheel hub falls on the turntable 61 from the unloading position of the conveying seat 1, the inclined surface of the pushing plate 71 can guide the automobile wheel hub to rush onto the turntable 61, and the pushing plate 71 can fit the outer contour of the wheel hub through the U-shaped structure, naturally guiding the wheel hub into the predetermined position to avoid deflection and jamming; during interception, the side wall of the pushing plate 71 can absorb the inertial impact of the wheel hub to prevent the wheel hub from rebounding and tipping after collision; at the same time, the U-shaped pushing plate 71 does not require complex sensors and power devices, and can achieve reliable interception by relying on the physical structure, reducing maintenance costs; When the automobile wheel hub falls on the turntable 61, the automobile wheel hub is rubbed by the friction plate 8 with multiple dots. The friction plate 8 is fixed at the opening of the fence plate 62 and contacts the automobile wheel hub first, which can reduce the inertial force generated when the automobile wheel hub falls, play the role of buffering and sorting the automobile wheel hub, and at the same time can achieve the effect of protecting the pushing plate 71; During the process of conveying and packaging automobile wheel hubs on a curve, in order to ensure the stability of conveying the automobile wheel hubs, the conveying seat 1 at the front end is set as the highest point, and then the subsequent conveying seats 1 are set to present a height difference. After the automobile wheel hub is placed on the front conveying seat 1 for conveying, it is conveyed from high to low to the rear end. When passing through the turntable 61 in the middle, the height of the top surface of the turntable 61 is lower than the height of the front end, but the height of the top surface of the turntable 61 is higher than the height of the rear end, which also realizes the height difference and improves the effect of high-speed conveying of automobile wheel hubs on curves.
