Description

A three-wheeled motorcycle assembly line based on industrial robots Technical Field

[0001] This invention relates to the field of assembly line technology, and more specifically to a three-wheeled motorcycle assembly line based on industrial robots. Background Technology

[0002] The three-wheeled motorcycle assembly line is a core component of modern motorcycle manufacturing, a complex automated system integrating material conveying, process assembly, and online inspection. This production line is typically designed with a modular approach to meet the mixed-production needs of different vehicle types, such as freight three-wheelers, agricultural three-wheelers, or electric three-wheelers. Its main structure often uses plate chain or double-speed chain conveyors. The line length and number of workstations can be customized according to production capacity. Common assembly line lengths range from tens to hundreds of meters; for example, some are designed to be 40 meters long with approximately 13 alignment workstations, while others are as long as 100 meters to accommodate more complex assembly processes. The line speed is typically adjustable steplessly between 0.3 meters and 6 meters per minute via a variable frequency motor, supporting both continuous flow and intermittent operation modes to ensure consistent operating rhythm at each workstation and achieve optimal production efficiency. Three-wheeled motorcycle assembly lines based on industrial robots represent a core direction for the industry's transformation from traditional manufacturing to intelligent manufacturing. Their core characteristic lies in the automation and intelligent upgrading of key processes through robotic technology. In this production model, the application of industrial robots is primarily focused on the welding process, which is a key step in improving frame quality and production efficiency.

[0003] Furthermore, modern three-wheeled motorcycle assembly lines not only emphasize the assembly process but also deeply integrate quality inspection into the line design. The end of the production line typically features a separate testing and inspection area equipped with specialized equipment such as brake performance testers and wheel balancing machines to rigorously inspect vehicles coming off the line. To ensure operational safety and production flexibility, multiple emergency stop switches are evenly distributed along both sides of the line, and the tooling fixtures are often designed to be universal and adjustable, compatible with different wheelbase models. A quick mold change system enables rapid switching between multiple product types. The entire production line, working in conjunction with loading / unloading mechanisms and auxiliary equipment such as return plate lifts, achieves the recycling of tooling plates, thus forming an efficient, continuous, and flexible vehicle assembly and manufacturing unit.

[0004] However, in the existing technology, the three-wheeled motorcycle assembly line can only move in a straight line during the assembly process, which cannot fully expose the assembly position in the robot's operating area.

[0021] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0022] As shown in Figures 1 to 6, an embodiment of the present invention provides a three-wheeled motorcycle assembly production line based on an industrial robot, including an installation support frame 1, a conveyor track 2, a planar support component 3, and an assembly operation table 4.

[0023] Specifically, the conveyor track 2 is mounted on the mounting support frame 1, and the conveyor track 2 is provided with a positioning component 5 for positioning the three-wheeled motorcycle frame.

[0024] The planar support 3 is disposed on the mounting frame 1, and the planar support 3 is in contact with the inner top surface of the conveyor track 2 and slides in contact with it. The planar support 3 is used to provide planar support for the conveyor track 2 and to enable the conveyor track 2 to transport the three-wheeled motorcycle frame in a planar manner.

[0025] The assembly platform 4 is mounted on the mounting support frame 1. The assembly platform 4 is located above the conveyor track 2. The three-wheeled motorcycle is transported to the assembly platform 4 via the conveyor track 2. The assembly platform 4 adjusts the position of the three-wheeled motorcycle by rotating it. After the three-wheeled motorcycle is assembled, it is released onto the conveyor track 2.

[0026] In this embodiment, the three-wheeled motorcycle frame is gripped and placed onto the positioning member 5 by a robotic arm, awaiting transport by the conveyor belt 2. Subsequently, the conveyor belt 2 transports the three-wheeled motorcycle frame above it towards the assembly platform 4. During the transport of the three-wheeled motorcycle frame, the planar support member 3 provides horizontal support to the inner top surface of the conveyor belt 2, enabling the conveyor belt 2 to transport the three-wheeled motorcycle frame horizontally. When the positioning member 5 transports the three-wheeled motorcycle frame to the assembly platform 4, the positioning member 5, driven by the conveyor belt 2, pushes the three-wheeled motorcycle frame onto the assembly platform 4 and keeps it stationary. The three-wheeled motorcycle frame on the assembly platform 4 can be assembled by an industrial robot. During the assembly process, the assembly platform 4 can rotate the three-wheeled motorcycle frame, facilitating comprehensive assembly operations by the industrial robot. After the three-wheeled motorcycle frame is assembled, the subsequent three-wheeled motorcycle frames will be pushed off the assembly platform 4. At the same time, the subsequent three-wheeled motorcycle frames will enter the assembly platform 4 one by one, realizing the continuous assembly process of the three-wheeled motorcycle frames.

[0027] Compared to existing technologies, this solution utilizes the cooperation between the conveyor track 2 and the positioning component 5 to achieve the positioning and transport of the three-wheeled motorcycle frame on the conveyor track 2, thereby moving the three-wheeled motorcycle frame to the assembly workbench 4. This allows for adjustment of the assembly posture of the three-wheeled motorcycle frame, facilitating subsequent assembly operations by the industrial robot. Furthermore, the planar support component 3 provides horizontal support to the conveyor track 2, ensuring stable transport of the three-wheeled motorcycle frame on the track strips, thus improving the overall stability of the production line.

[0028] It should be noted that the specific number of assembly operation tables 4 can be determined according to the actual assembly process and technology. Multiple tables can be set on the mounting support frame 1 to realize the assembly line assembly of three-wheeled motorcycles.

[0029] Furthermore, the mounting support frame 1 includes a support platform 6, a conveying roller 7, and a conveying motor 8.

[0030] Specifically, there are two support platforms 6, which are arranged in parallel, and a support base is fixedly installed at the bottom of both support platforms 6.

[0031] Two conveyor rollers 7 are provided, and the two conveyor rollers 7 are respectively rotatably installed at both ends of the bearing platform 6. The conveyor rollers 7 are used to drive the conveyor track 2 to rotate.

[0032] The conveying motor 8 is mounted on the side of the bearing platform 6, and the conveying motor 8 is connected to one of the conveying rollers 7 through a reducer 9.

[0033] In this embodiment, driven by the conveyor motor 8, the reducer 9 converts the high-speed output of the conveyor motor 8 into a low-speed output, which in turn drives one of the conveyor rollers 7 to rotate. Under the transmission of the conveyor roller 7, the conveyor track 2 rotates, and the conveyor track 2 transports the three-wheeled motorcycle frame located above it, and works with the assembly platform 4 and the industrial robot to realize the assembly operation of the three-wheeled motorcycle.

[0034] In one specific embodiment, the conveyor track 2 includes multiple track strips, which are rotatably connected and form a ring structure. The conveyor roller 7 is configured as a regular polygonal prism structure that matches the track strips. The track strips are used to mount the positioning element 5 and to directionally convey the three-wheeled motorcycle frame. The regular polygonal prism structure of the conveyor roller 7 can effectively convey the track strips, effectively solving the problem of slippage of the conveyor track 2.

[0035] In addition, the conveyor motor 8 is a servo motor. A servo motor is an engine that controls the operation of mechanical components in a servo system; it is a type of auxiliary motor with indirect speed change. Servo motors can control speed with very high positional accuracy, converting voltage signals into torque and speed to drive the controlled object. The rotor speed of a servo motor is controlled by the input signal and can respond quickly. In automatic control systems, it is used as an actuator and has characteristics such as a small electromechanical time constant and high linearity. It can convert received electrical signals into angular displacement or angular velocity output on the motor shaft. The servo motor 8 can convey the three-wheeled motorcycle frame at an appropriate speed and distance according to the assembly needs and requirements of the three-wheeled motorcycle.

[0036] Furthermore, the positioning element 5 includes a front wheel positioning strip 10 and a rear wheel drive positioning device.

[0037] Specifically, the front wheel positioning strip 10 is fixedly installed on the track strip, and the front wheel positioning strip 10 is located in the middle of the track strip.

[0038] Two rear-wheel drive positioners are provided. The two rear-wheel drive positioners are detachably installed on the track strips, and the two rear-wheel drive units are symmetrically distributed on both sides of the central axis of the front wheel positioning strip 10. The rear-wheel drive positioners are used to position the three-wheeled motorcycle frame and push the three-wheeled motorcycle frame to move onto the assembly support platform.

[0039] In one specific embodiment, the rear wheel drive positioner includes a mounting base 11, a drive bracket 12, and a drive roller 13. The mounting base 11 is detachably mounted to the track strip by bolts. The drive bracket 12 is fixedly disposed on the mounting base 11, and the drive bracket 12 is configured in an L-shape. The drive roller 13 is horizontally and rotatably mounted on the top end of the drive bracket 12, and the drive roller 13 is in close contact with the rear wheel of the three-wheeled motorcycle frame.

[0040] The front wheel positioning strip 10 is designed in a zigzag shape, and the front wheel of the three-wheeled motorcycle frame abuts against the front wheel positioning strip 10. Simultaneously, the rear wheels of the three-wheeled motorcycle frame abut against two drive rollers 13. When the three-wheeled motorcycle frame approaches the assembly worktable 4, the drive rollers 13, driven by the conveyor belt 2, push the three-wheeled motorcycle frame onto the assembly worktable 4. Once the three-wheeled motorcycle frame is on the assembly worktable 4, the industrial robot can perform assembly operations on the three-wheeled motorcycle frame.

[0041] Furthermore, the planar support member 3 includes a horizontal support plate 14, a horizontal roller 15, and a vertical correction roller 16.

[0042] Specifically, the horizontal support plate 14 is fixedly disposed between the two bearing platforms 6, and the horizontal support plate 14 is located below the inner top surface of the conveyor belt 2. The upper surface of the horizontal support plate 14 is provided with multiple mounting grooves 17.

[0043] The horizontal roller 15 is rotatably mounted in the mounting groove 17, and the horizontal roller 15 is in contact with the inner top surface of the conveyor belt 2.

[0044] Two vertical correction wheels are provided, and the two vertical correction wheels are vertically and rotatably mounted on the horizontal support plate 14. The two vertical correction wheels are distributed on both sides of the conveyor track 2 and are in close contact with the two sides of the conveyor track 2.

[0045] In this embodiment, multiple sets of horizontal rollers 15 are provided. Multiple horizontal rollers 15 in each set are rotatably mounted in a strip shape via a mounting shaft. The horizontal rollers 15 mounted on the mounting shaft are installed within the mounting groove 17. After prolonged use, when a horizontal roller 15 is damaged, the mounting shaft and the horizontal roller 15 can be directly removed from the mounting groove 17 for easy replacement.

[0046] When the conveyor track 2 is in operation, the top of the horizontal roller 15 is slightly higher than the horizontal support plate 14, providing support for the conveyor track 2. Simultaneously, the horizontal roller 15 rotates with the conveyor track 2, effectively reducing the frictional resistance between the conveyor track 2 and the horizontal roller 15, ensuring stable operation of the conveyor track 2. Furthermore, the cooperation between the horizontal roller 15 and the horizontal support plate 14 ensures that the conveyor track 2 maintains horizontal transport, thereby enabling stable transport of the three-wheeled motorcycle frame.

[0047] Furthermore, the assembly workbench 4 includes an assembly frame 18, an assembly platform 19, a mounting base 20, and a hub motor 21.

[0048] Specifically, the assembly frame 18 is fixedly disposed between the two bearing platforms 6.

[0049] The assembly platform 19 is rotatably mounted on the assembly frame 18, and the assembly platform 19 is provided with a bearing plane for supporting the frame of the three-wheeled motorcycle.

[0050] The mounting base 20 is fixedly mounted on the assembly frame 18, and the hub motor 21 is fixedly mounted on the mounting base 20. The output end of the hub motor 21 is connected to the assembly platform 19 for transmission.

[0051] In this embodiment, there is a reserved space between the assembly platform 19 and the conveyor track 2. The assembly platform 19 is provided with a positioning groove 24 that matches the frame of the three-wheeled motorcycle, and the entry side of the positioning groove 24 has a chamfered structure.

[0052] After the three-wheeled motorcycle frame is placed on the positioning piece 5 on the conveyor belt, it moves towards the assembly platform 4 along the conveyor belt 2. When the three-wheeled motorcycle frame approaches the assembly platform 19, the drive roller 13 pushes it along the positioning groove 24 onto the assembly platform 19. As the conveyor belt 2 rotates, the drive roller 13 pushes the three-wheeled motorcycle frame onto the assembly platform 19, and the frame remains stably held on the platform, facilitating subsequent assembly of the frame by the industrial robot.

[0053] Furthermore, the bearing plane has a guiding plane 22 and a parking plane 23.

[0054] Specifically, the guide plane 22 is inclined upward along the direction of travel of the three-wheeled motorcycle, and the guide plane 22 is used to guide the three-wheeled motorcycle frame into the parking plane 23.

[0055] The parking plane 23 is inclined downward along the direction of travel of the three-wheeled motorcycle. The parking plane 23 is used to drive the three-wheeled motorcycle to tilt downward and to restrict the three-wheeled motorcycle from sliding downward through the positioning groove 24.

[0056] In this embodiment, the drive roller 13 pushes the tricycle frame along the positioning groove 24 toward the assembly platform 19. The front wheel of the tricycle frame moves to the parking plane 23 via the guide plane 22, while the rear wheel of the tricycle frame enters the guide plane 22. Because the overall center of gravity of the tricycle frame is biased toward the parking plane 23 when the front wheel of the tricycle frame abuts against the end side wall of the positioning groove 24, the tricycle frame is stably held on the assembly platform 19, facilitating subsequent assembly operations.

[0057] During the process of driving the three-wheeled motorcycle frame to the assembly platform 19, the drive roller 13 gradually contacts the bottom of the wheels of the three-wheeled motorcycle frame. After the three-wheeled motorcycle frame is fully in the assembly platform 19, the drive roller 13 passes under the wheels of the three-wheeled motorcycle frame, completing the position switch of the three-wheeled motorcycle frame from the conveyor track 2 to the assembly platform 19.

[0058] In one specific embodiment, the assembly platform 19 has two reserved channels 25, which are symmetrically distributed on both sides of the assembly platform 19. The reserved channels 25 are used to provide passageways for the positioning component 5. The reserved channels 25 are designed so that after the drive roller 13 completes pushing the three-wheeled motorcycle frame, the drive roller 13 passes through the reserved channels 25 without affecting the normal operation of the conveyor track 2.

[0059] Compared to existing technologies, this invention has at least the following advantages: By utilizing the cooperation of the conveyor belt and the positioning component, the three-wheeled motorcycle frame can be positioned and transported on the conveyor belt, thereby moving the frame to the assembly workbench. This allows for adjustment of the frame's assembly posture, facilitating subsequent assembly operations by industrial robots. Furthermore, the planar support component provides horizontal support to the track strips, ensuring stable transport of the three-wheeled motorcycle frame on the track strips, thus improving the overall stability of the production line.

[0060] Furthermore, the assembly platform of this invention, in conjunction with the conveyor belt and positioning components, enables the switching of the three-wheeled motorcycle frame from the conveyor belt to the assembly platform, facilitating the assembly operation of the three-wheeled motorcycle frame by the industrial robot. Simultaneously, after the assembly operation of the three-wheeled motorcycle frame is completed, the frame continues to be transported, ensuring the stable operation of the three-wheeled motorcycle frame assembly production line.

[0061] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
