Description

Technical Field

[0001] The invention belongs to the technical field of tire flipping, and in particular relates to a movable 90-degree tire flipping mechanism. Background Art

[0002] As the global automotive industry accelerates its transformation toward intelligent and flexible manufacturing, the efficiency and precision of tire assembly have become key factors limiting vehicle production schedules. Tire assembly typically relies on manually operated tire manipulators, which pick up tires from tire-carrying carts and then install them into the vehicle body. Due to workspace and gripping requirements, tires must be flipped 90° to a standing position before being moved to a gripping station, where they are then gripped and installed by a tire gripper.

[0003] A Chinese patent with application number CN2017108804372 discloses a 90° flip delivery mechanism for a tire line. One end of the support frame extends into the protective frame. A rotating shaft and a rotating cylinder are fixed on the support frame inside the protective frame. A delivery track and a sliding cylinder are fixed on the support frame outside the protective frame. A roller is rotatably installed on the rotating shaft. The roller is connected to the piston rod end of the rotating cylinder. A tire bracket is slidably installed on the delivery track. The tire bracket is located at the exit end of the roller, and the installation height of the tire bracket is lower than the installation height of the roller. The tire bracket is connected to the sliding cylinder. The conveying direction of the roller is perpendicular to the conveying direction of the delivery track. A side guide roller mounting plate is fixed on one side of the delivery track, and a side guide roller is installed on the side guide roller mounting plate. An anti-collision plate is fixed on the support frame at the end position of the delivery track. The present invention has a simple, compact and reasonable structure, reduces the buffer stations of the tire conveyor line, and reduces costs. At the same time, the tire is in a vertical position, which makes it more convenient for the robot to pick up the parts, reducing the cost of the robot. However, in this application, when the tire enters the roller conveyor, it is conveyed by the roller conveyor to be turned 90 degrees, and then transported to the robot gripping position on the guide roller. The entire process is cumbersome and time-consuming. Summary of the Invention

DETAILED DESCRIPTION

[0019] like Figure 1-5 As shown: A movable 90° tire flipping mechanism, including a traveling mechanism 1, a mounting frame 21 is slidably mounted on the traveling mechanism 1, a first drive group 13 is provided at one side of the traveling mechanism 1, a second drive group 22 is provided on one side of the mounting frame 21, a flip frame 28 is provided at the power output end of the second drive group 22, the flip frame 28 is configured as a semi-open structure, a plurality of tire conveying rollers 32 are rotatably mounted on one side of the flip frame 28, a plurality of guide conical rollers 33 are provided on the side of the flip frame 28 opposite to the tire conveying rollers 32, a tire pushing mechanism 4 is provided on the side of the flip frame 28 that is perpendicular to the tire conveying rollers 32 and the guide conical rollers 33, and a third drive group 31 for driving the tire conveying rollers 32 to rotate is provided on the side of the flip frame 28 close to the second drive group 22.

[0020] The movable 90° tire flipping mechanism is used between the output end of the tire conveyor line and the tire loading trolley. The movable 90° tire flipping mechanism receives the tire output from the tire conveyor line, flips it 90° into an upright state through the flipping frame 28, and then places it on the tire loading trolley. The manipulator then grabs it. During this period, the flipping frame 28 moves to the output end of the tire conveyor line to receive the tire. The flipping frame 28 then rotates 90° during the return movement, so that the tire is in an upright state in the flipping frame 28. When the flipping frame 28 carries the tire back to its initial position, the tire pushing mechanism 4 is actuated to transport the tire to the tire loading trolley. This process is completed only during the action of the flipping frame 28, saving half the time.

[0021] like Figure 2 As shown, the accompanying mechanism 1 includes two parallel and spaced rails 11, on which an accompanying frame 12 is slidably mounted. The first driving group 13 and the mounting frame 21 are fixedly mounted on the accompanying frame 12, and the first driving group 13 drives the accompanying frame 12 to move.

[0022] In this embodiment, the two rails 11 can be detachably mounted on the bracket at the tire receiving position according to the height of the tire being transported, so as to facilitate adjustment at any time.

[0023] Blockers 15 are fixedly installed at both ends of one of the rails 11. The function of the blocker 15 is the same as that of a proximity switch, and it can control the mounting frame 21 to slide back and forth. The blocker 15 is commercially available.

[0024] The accompanying frame 12 is made by welding a plurality of square tubes of different lengths. Track wheels are respectively provided at the four corners of the bottom surface of the accompanying frame 12 . The four track wheels match the track 11 and can roll on the track 11 .

[0025] Among the four track wheels, two track wheels perpendicular to the track 11 are connected by a transmission shaft, one end of the transmission shaft is fixedly connected to the power output end of the first drive group 13, and the first drive group 13 is fixedly installed at a side position of the accompanying frame 12.

[0026] In this embodiment, the first driving group 13 is driven by a motor connected to a reducer, and the motor and reducer can be obtained commercially.

[0027] A traveling drag chain 14 is also fixedly installed on the bracket of the tire connection position near the first drive group 13. One end of the traveling drag chain 14 is fixedly connected to the traveling frame 12. The traveling drag chain 14 is commercially available and can protect the cables of the first drive group 13 and plan the moving path of the traveling frame 12.

[0028] The installation frame 21 is made by welding square tubes of different lengths.

[0029] The second drive group 22 is also driven by a motor connected to a reducer, and a drive shaft 23 is provided at the power output end of the second drive group 22 .

[0030] At least two spaced-apart bearings 24 are fixedly mounted on the mounting frame 21 at positions corresponding to the drive shaft 23 . The bearings 24 are sleeved on the drive shaft 23 to ensure smooth rotation of the drive shaft 23 .

[0031] A detection assembly 26 is sleeved on the outer surface of one end of the driving shaft 23 away from the second driving group 22 .

[0032] A detection switch 25 is fixedly mounted on the mounting frame 21 near the detection assembly 26 , and the detection assembly 26 matches the detection switch 25 .

[0033] The detection assembly 26 includes a ring sleeve that is sleeved on the drive shaft 23. Two detection heads are vertically arranged on the outer surface of the ring sleeve, and the two detection heads are arranged at 90°. When the drive shaft 23 rotates, the detection heads are driven to rotate. The detection heads rotate 90° and contact the detection switch 25. The detection switch 25 feeds back the signal. Its principle is the same as that of commercially available proximity switches and can be obtained commercially, so it will not be described in detail here.

[0034] In this embodiment, the two detection heads correspond to the initial 0° and 90° rotation states respectively. The 0° state is used to detect the horizontal position of the flip frame 28 connected to the tire, and the 90° state is used to detect the flip frame 28 flipping 90° to flip the tire to an upright position.

[0035] A mounting plate 27 is fixedly mounted on the end of the drive shaft 23 away from the second drive group 22 .

[0036] like Figure 4 As shown, the flip frame 28 includes a first mounting plate 280 fixedly mounted on the mounting disk 27. The first mounting plate 280 is fixedly connected to the mounting disk 27 near the edge. With this design, the second drive group 22 drives the drive shaft 23 to rotate 90° counterclockwise, and then drives the flip frame 28 to rotate 90° counterclockwise. When the mounting disk 27 is fixedly connected to the first mounting plate 280 near the edge, the radius of the area required for the flip frame 28 to rotate counterclockwise is small, saving rotation space.

[0037] A first frame 282 and a second frame 283 are fixedly mounted on both sides of the first mounting plate 280 in the height direction.

[0038] The first frame 282 and the second frame 283 are parallel to each other.

[0039] The plurality of tire conveying rollers 32 are arranged in parallel and at intervals in the second frame 283 along the length direction of the second frame 283 .

[0040] The plurality of guide tapered rollers 33 are arranged in parallel and at intervals in the first frame 282 along the width direction of the first frame 282 .

[0041] In this way, the arrangement direction of the plurality of tire conveying rollers 32 is perpendicular to the arrangement direction of the plurality of guide conical rollers 33 .

[0042] The third drive group 31 is fixedly mounted on the first mounting plate 280 . The power output end of the third drive group 31 is transmission-connected to a plurality of tire conveying rollers 32 , and can drive the tire conveying rollers 32 to rotate and convey the tires into the turning frame 28 .

[0043] The guide conical roller 33 includes a rotating roller rotatably mounted on the first frame 282, and polyurethane protective sleeves are provided at both ends of the rotating roller. With this design, when the tire enters the flip frame 28, the polyurethane protective sleeves can protect the tire wheel hub and avoid damage.

[0044] In this embodiment, the third drive group 31 is also driven by a motor connected to a reducer, and the transmission connection between the third drive group 31 and the multiple tire conveying rollers 32 can be achieved through chains and sprockets, which is well known in the prior art and will not be described in detail here.

[0045] The third driving group 31 drives the plurality of tire conveying rollers 32 to rotate at the same speed as the tire conveying speed in the previous step, so that the tires can be transferred to the plurality of tire conveying rollers 32 without differential speed.

[0046] A second mounting plate 281 is fixedly installed on one side of the first mounting plate 280 away from the open end of the flip frame 28. The second mounting plate 281 is fixedly connected to the first frame 282 and the second frame 283 at the same time. In this design, the first mounting plate 280, the second mounting plate 281, the first frame 282 and the second frame 283 form a semi-open structure of the flip frame 28.

[0047] A tire placement area is provided between the first mounting plate 280 , the second mounting plate 281 , the first frame 282 , and the second frame 283 .

[0048] like Figure 4-5 As shown, the tire pushing mechanism 4 includes a cylinder mounting frame 42 fixedly mounted on a side of the second mounting plate 281 away from the tire placement area, and the cylinder mounting frame 42 is also located on the second mounting plate 281 away from the mounting frame 21.

[0049] The cylinder 41 is fixedly mounted on the cylinder mounting frame 42 . The power output shaft of the cylinder 41 passes through the second mounting plate 281 and is hinged to a hinge plate 44 . One end of the hinge plate 44 is hinged to the power output end of the cylinder 41 .

[0050] The other end of the hinge plate 44 is hinged to two hinge seats 43 symmetrically spaced apart, and the two hinge seats 43 are fixedly mounted on the second mounting plate 281 at the same time.

[0051] The articulation between the articulation seat 43 and the articulation plate 44 and the articulation between the articulation plate 44 and the power output shaft of the cylinder 41 are both achieved through the cooperation between the articulation shaft and the articulation hole, which is common knowledge in the prior art and the specific structure will not be described in detail here.

[0052] In this embodiment, in the initial state, the power output shaft of the cylinder 41 is in an extended state, and the hinged plate 44 is ensured to be arranged parallel to the second mounting plate 281. When the tire in the tire placement area is turned 90° by the turning frame 28 and becomes upright, the cylinder 41 is started to retract the power output shaft of the cylinder 41, pulling one end of the hinged plate 44 to move toward a position close to the second mounting plate 281 to form a slope, and then the tire in the tire placement area automatically rolls onto the tire carrying trolley.

[0053] The hinge plate 44 is also provided with a detection sensor which can detect whether the tire is in place, which is not shown in the figure. When the tire enters the tire placement area, the detection sensor is triggered and the detection sensor then feeds back a signal.

[0054] The accompanying frame 12 is also provided with an electric control system for controlling the operation of the mechanism, which is not indicated in the figure. The control ends of the first drive group 13, the second drive group 22 and the third drive group 31 are all electrically connected to the electric control system.

[0055] The control end of the cylinder 41 is electrically connected to the electronic control system.

[0056] The blocker 15 , the detection switch 25 and the signal output end of the detection sensor are all electrically connected to the electric control system.

[0057] During use, the mechanism is installed at the output end of the tire conveyor line to ensure that the tire conveyor roller 32 is flush with the output end of the tire conveyor line. At this time, the first drive group 13 is controlled to start, and the flip frame 28 is controlled to reach the output end of the tire conveyor line, triggering the corresponding blocker 15 to reach the position. The third drive group 31 is activated to ensure that the tire continues to move toward the hinge plate 44. When the tire enters the tire conveyor roller 32, the detection sensor on the hinge plate 44 is triggered, proving that the tire is placed in the tire placement area. The electronic control system controls the activation of the second drive group 22 and the first drive group 13, and controls the flip frame 28 to rotate 90 degrees simultaneously during the return movement. During this period, the detection switch 25 is triggered by the detection head at the 90° position. When the accompanying frame 12 moves back, the blocker 15 is triggered. The blocker 15 feeds back a signal to the electronic control system, which controls the activation of the cylinder 41. The cylinder 41 controls the retraction of its power output shaft, driving one end of the hinge plate 44 to move downward to form a slope. The tire can then roll upright onto the tire loading trolley to be grabbed.

[0058] At this time, the electronic control system receives a signal from the detection sensor that there is no tire in the tire placement area, controls the activation of the second drive group 22, and rotates the flip frame 28 until the detection head at 0° triggers the detection switch 25. At the same time, the first drive group 13 is activated to control the flip frame 28 to reach the output end of the tire conveyor line for the next tire flipping cycle.

[0059] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
