Description

Technical Field

[0001] This utility model relates to the field of tire processing technology, specifically to a robotic arm for tire handling. Background Technology

[0002] Tire manufacturing is a highly complex systems engineering project, with its processes encompassing multiple precision stages, from raw material pretreatment and tire carcass molding to high-temperature vulcanization and final quality inspection. With the rapid development of industrial automation technology, robotic arms are increasingly being used in tire production, providing new technological pathways to improve production efficiency.

[0003] Under the existing production model, after the processed tires are output through the conveyor system, they need to be picked up individually and stacked layer by layer by manual labor or robotic arms to facilitate subsequent warehousing, transportation, and packaging operations. Although this discrete operation method can guarantee basic process requirements, it has revealed obvious efficiency constraints in actual operation: each tire needs to go through an independent picking-handling-stacking cycle, making it difficult to improve the overall production efficiency and fully match the high-speed output capacity of modern tire production lines. Utility Model Content

[0004] The purpose of this invention is to provide a robotic arm for tire handling, so as to solve the problem of low efficiency in tire handling operations in the prior art.

[0006] Preferably, the clamp includes: a rhomboid telescopic frame located at the end of the mounting rod; and a drive assembly connected to the mounting rod and the rhomboid telescopic frame, which drives the rhomboid telescopic frame to produce radial telescopic deformation, thereby realizing the opening and closing of the clamp.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figures 1-5 As shown, this utility model proposes a tire handling robotic arm, including a robotic arm 1. The robotic arm 1 has a clamping mechanism at its working end, comprising a mounting part 2, a mounting rod 3, and a gripper 4. The mounting part 2 is tightly connected to the working end of the robotic arm 1 via a rotary bearing. This connection allows the mounting part 2 to rotate stably around its axis with the power of the robotic arm 1, thereby flexibly adjusting the angle of the gripper 4 during handling to adapt to different tire stacking arrangements. The mounting rod 3 slides with the mounting part 2 and is driven to move axially via a linear drive mechanism. The gripper 4 is located at the end of the mounting rod 3 and uses a strut 404 to grip the bottom tire in the stack, achieving simultaneous clamping of multiple tires.

[0024] The robotic arm 1, drive mechanism and gripping mechanism are connected by an external control system to coordinate the gripping action and lifting motion. The specific control method of the control system is not within the protection scope of this experimental novel and will not be described again.

[0025] Specifically, the clamp 4 includes a rhomboid telescopic frame and a drive assembly. The rhomboid telescopic frame is located at the end of the mounting rod 3. The drive assembly is connected to the mounting rod 3 and the rhomboid telescopic frame. The drive assembly drives the rhomboid telescopic frame to produce radial telescopic deformation, thereby realizing the opening and closing of the clamp 4.

[0026] The drive assembly includes a slide rod 405 and a mounting base 402. The slide rod 405 is slidably connected to the mounting rod 3. The mounting base 402 is fixed to the end of the slide rod 405 away from the mounting rod 3 and is used to fix the diamond-shaped telescopic frame. The slide rod 405 is driven to move axially along the mounting rod 3 by a power source. The power source is an electric push rod, the cylinder of which is fixed to the mounting rod 3. The end of the push rod is connected to the slide rod 405. The mounting rod 3 has a blind hole at its center along its length for sliding engagement with the slide rod 405.

[0027] The rhomboid telescopic frame includes a first component and a second component. The first component includes multiple support rods 404 distributed circumferentially along the mounting rod 3, and the support rods 404 are rotatably connected to the mounting rod 3. The second component includes multiple connecting rods 401 corresponding to the support rods 404. One end of each connecting rod 401 is hinged to the corresponding support rod 404, and the other end is rotatably connected to the mounting base 402. The support rods 404 and the connecting rods 401 form a telescopic rhomboid telescopic frame. The rhomboid telescopic frame generates radial telescopic deformation by driving the mounting base 402 and the mounting rod 3 to move axially relative to each other through the driving slide rod 405.

[0028] Furthermore, a tire anti-detachment hook 403 is provided at the connection between the support rod 404 and the connecting rod 401. The hook 403 is arc-shaped and can hook onto the inner edge of the tire, effectively preventing the tire from accidentally falling off due to vibration or other external forces during transportation, which greatly improves the safety and reliability of transportation operations.

[0029] Working principle: In the initial state, the diamond-shaped telescopic frame in the gripper 4 is in a retracted state, and all the support rods 404 are gathered around the mounting rod 3. The robotic arm 1 moves the gripper above the tire, and the linear drive mechanism drives the mounting rod 3 downward, so that the gripper 4 passes through the hollow part of the tire. The electric push rod in the drive assembly pushes the slide rod 405 to move circumferentially. Through the mounting seat 402, the connecting rod 401 drives the support rod 404 to expand radially and lock the inner wall of the tire. The robotic arm 1 lifts the gripper to a new position, and the drive assembly reverses its action to retract the support rod 404 and lower the tire. Repeating the above operation can simultaneously grip tires and form a stack. In this utility model, a single tire is gripped for the first time, and the bottom tire can be used as a support platform for the second gripping. Subsequent gripping can stack tires to form a stack. Compared with the existing independent gripping-carrying-stacking operation cycle, this realizes the automation and efficiency of tire handling operations, which can significantly improve production efficiency and reduce labor intensity.

[0030] Based on the above embodiments, such as Figures 3-5As shown, the mounting part 2 is provided with a guide through hole that matches the size of the mounting rod 3, and the mounting rod 3 and the mounting part 2 are slidably connected through the guide hole; the side of the mounting rod 3 is provided with a sliding groove 302 arranged along its length direction, and the inner wall of the guide through hole is provided with a protrusion that slides with the sliding groove 302.

[0031] Furthermore, the mounting part 2 has a drive mechanism mounting cavity inside, which is connected to the guide through hole;

[0032] Specifically, the linear drive mechanism includes a gear 201, a worm gear 202, and a worm 204. The gear 201 is rotatably mounted in the mounting cavity via a rotating shaft. The mounting rod 3 is provided with a rack 301 arranged along its length direction. The gear 201 meshes with the rack 301. The worm 204 is fixedly connected to the rotating shaft of the gear 201 and is coaxially distributed with the gear 201. The worm 204 is rotatably connected to the inner wall of the mounting chamber and meshes with the worm gear 202 for transmission. A motor that drives its rotation is provided in the mounting cavity.

[0033] In this embodiment, the drive motor 203 inside the mounting cavity starts and drives the worm 204 to rotate. The worm 204 meshes with the worm wheel 202, driving the rotating shaft and gear 201 to rotate. The gear 201 meshes with the rack 301 on the mounting rod 3, driving the mounting rod 3 to move on the mounting part 2. In this embodiment, through the innovative combination of the worm wheel 202, worm 204, gear 201, and rack 301, a linear drive system with high thrust, high precision, and self-locking function is realized in a compact space.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
