[0016] 1. This utility model introduces a design combining a flipping mechanism and a feeding mechanism. The flipping mechanism achieves precise clamping and flipping of the lower limb tube through the sliding of the slide block on the slide rail and the drive motor B driving the robotic arm. The feeding mechanism utilizes the mutual driving connection between the drive motor A and the lead screw to ensure the robotic arm can move smoothly along a preset path.

[0037] Figure 1 This is a schematic diagram of the overall assembly structure of this utility model. Figure 2 This is a schematic diagram of the structure of this utility model. Figure 3 This is a schematic diagram of the assembly structure between the middle limb tube and the lower limb tube of this utility model. Figure 4 This is a schematic diagram of the internal structure of the lower limb tube of this utility model, as shown below. Figure 1 , Figure 2 , Figure 3 and Figure 4 The device shown is an assembly device for middle and lower limb tubes, including a flipping mechanism, a feeding mechanism and a positioning mechanism. The feeding mechanism and the positioning mechanism are both mounted on the worktable 1, and the flipping mechanism is mounted on the feeding mechanism.

[0038] The feeding mechanism of this utility model includes a frame 401, a drive motor A404, and a lead screw 406. The frame 401 is fixedly connected to the worktable 1, serving as the main support structure of the feeding mechanism and supporting components such as the drive motor A404, the lead screw 406, and two slide rails 403. It provides a stable mounting base for other components. The drive motor A404 is fixedly connected to one side of the frame 401, and its output end is mutually driven by the lead screw 406. The rotation of the motor is converted into linear motion of the lead screw 406, which in turn pushes the slide block 405 to move along the slide rails 403, achieving precise control of the position of the flipping mechanism. Two slide rails 403 are provided on the frame 401, providing a guide path for the slide block 405, ensuring its stability and straightness during movement, and reducing motion errors.

[0039] The flipping mechanism of this invention includes a slide 405, a drive motor B407, a motor shaft 408, and a robotic arm 409. The slide 405 is slidably connected to a slide rail 403 and can move along the slide rail 403, providing a movable base platform for the drive motor B407 and the robotic arm 409. It allows the entire flipping mechanism to translate along a predetermined path, thereby enabling the feeding operation of the lower limb tube 6 and inserting it into the middle limb tube 9. The drive motor B407 is mounted on one side of the slide 405. The output end of the drive motor B407 is mutually driven by the robotic arm 409 through the motor shaft 408. The drive motor B407 is responsible for driving the movement of the robotic arm 409. By controlling the rotation of the motor shaft 408, the position of the robotic arm 409 is rotated, enabling the robotic arm 409 to accurately perform the task of gripping and flipping the lower limb tube 6. The motor shaft 408 transmits the power of the drive motor B407 to the robotic arm 409, ensuring that the robotic arm 409 can accurately flip at a preset angle. A gripper 410 for gripping the lower limb tube 6 is installed on the robotic arm 409.

[0040] The positioning mechanism in this invention is located on one side of the frame 401. The positioning mechanism is used to clamp and position the middle limb tube 9. The positioning mechanism includes a support plate 411, a positioning seat 412, a fixing seat 413, and a fixing tail seat 416. The positioning seat 412, the fixing seat 413, and the fixing tail seat 416 are all fixedly connected to the support plate 411. The support plate 411 provides a common mounting plane for the positioning seat 412, the fixing seat 413, and the fixing tail seat 416, ensuring that the relative positions of these components remain unchanged, thereby providing a stable support and positioning environment for the middle limb tube 9. A groove is provided on the positioning seat 412 to accommodate the middle limb tube 9, ensuring that the middle limb tube 9 can maintain the correct position during assembly, preparing for the subsequent insertion of the lower limb tube 6.

[0041] This invention features a drive cylinder 414 fixedly connected to a fixed base 413. A fixed gripper 415 for clamping the middle limb tube 9 is driven and connected to the drive cylinder 414, ensuring a secure clamping of the middle limb tube 9 during assembly. The inner diameter of the middle limb tube 9 is larger than the outer diameter of the lower limb tube 6. Multiple through holes 901 are provided on the middle limb tube 9 to engage with the internal latches 601 of the lower limb tube 6, ensuring stability and easy disassembly after connection. A foot pad 8 is installed at one end of the lower limb tube 6, and a spring piece 602 is installed inside the lower limb tube 6. A latch 601 is provided on the spring piece 602, and the latch 601 engages with the through holes 901. When the lower limb tube 6 is inserted into the middle limb tube 9, the latch 601 automatically engages with the through holes 901 on the middle limb tube 9 through a flipping mechanism, forming a reliable connection point. The present invention has a support base 402 fixedly connected to the bottom of the frame 401. The support base 402 is fixedly installed on the workbench 1, providing additional support for the entire assembly device, enhancing the stability and load-bearing capacity of the overall structure, and ensuring reliability and safety during long-term operation.

[0042] In summary, the coordinated operation of the aforementioned components not only enables automated assembly of the middle limb tube 9 and the lower limb tube 6, but also significantly improves assembly accuracy and product quality, reduces the defect rate, simplifies the assembly process, and increases production efficiency.

[0043] Working principle:

[0044] 1. As the control center of the entire device, the control device 3 is responsible for coordinating the actions of all moving parts. When the device is started, it initializes the state of each motor and ensures that they are in the correct starting position.

[0045] 2. The lower limb tube 6 is sent to the limb tube delivery mechanism 2 by the operation of the first clamping and conveying mechanism 5. The lower limb tube 6 is sent to one side of the assembly mechanism 4 by the limb tube delivery mechanism 2. Then, the lower limb tube 6 on the assembly mechanism 4 is sent to the assembly mechanism 4 by the second clamping and conveying mechanism 7.

[0046] 3. Then place the middle limb tube 9 in the groove of the positioning seat 412 to ensure that its position is accurate. The driving cylinder 414 on the fixed seat 413 drives the fixing claw 415 to firmly clamp the middle limb tube 9 to prevent it from moving in subsequent operations.

[0047] 4. The robotic arm 409 of the flipping mechanism is adjusted to its initial position, ready to grasp the lower limb tube 6. The drive motor B407 starts, driving the robotic arm 409 to move via the motor shaft 408, so that the gripper 410 installed at the end of the robotic arm 409 accurately grasps the lower limb tube 6. The drive motor A404 starts working, converting the rotational motion into linear motion of the slide 405 along the slide rail 403 via the lead screw 406. The slide 405 drives the entire flipping mechanism (including the robotic arm 409 that has already grasped the lower limb tube 6) to move towards the middle limb tube 9, until the lower limb tube 6 approaches the entrance of the middle limb tube 9.

[0048] 5. Insertion Operation: Under the action of the feeding mechanism, the lower limb tube 6 is pushed into the middle limb tube 9 until the two are fully aligned. At this time, since the inner diameter of the middle limb tube 9 is larger than the outer diameter of the lower limb tube 6, the lower limb tube 6 can enter smoothly. Flipping and Snapping: To ensure that the lower limb tube 6 can be correctly aligned with the through hole 901 in the middle limb tube 9 and snapped in place, the drive motor B407 is restarted, and the mechanical arm 409 is rotated through the motor shaft 408, causing the lower limb tube 6 to flip at a preset angle. During the flipping process, the latches 601 on the spring piece 602 inside the lower limb tube 6 will align with the through hole 901 on the middle limb tube 9 as the lower limb tube 6 flips, and finally snap together, forming a stable and easily disassembled connection structure.

[0049] 6. Once the latch 601 has successfully engaged with the through hole 901 of the middle limb tube 9, the robotic arm 409 releases the lower limb tube 6 and returns to its initial position, ready for the next cycle of operation. The drive cylinder 414 of the positioning mechanism releases the fixing jaw 415, releasing the middle limb tube 9, completing one complete assembly process.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
