Detailed Implementation

[0027] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1:

[0029] Reference Figures 1 to 3This embodiment provides an automated welding production line for welding brackets, used for welding various brackets for electromechanical pipelines. Specifically, the automated welding production line for welding brackets in this embodiment includes a mobile working platform 1, a transfer mechanism 2, a welding robotic arm 4, and a wheel transmission mechanism 3, as detailed below.

[0030] The automated welding production line for welding brackets in this embodiment includes several movable work platforms 1 for placing brackets to be welded, a transfer mechanism 2 for moving the movable work platforms 1 along a first direction, a wheel transmission mechanism 3 for conveying the movable work platforms 1 along a second direction, and a welding robotic arm 4 for welding the brackets placed on the movable work platforms 1. The movable work platforms 1 cyclically move between a loading station 5, a pre-assembly station 6, a welding station 7, a quality inspection station 8, and a unloading station 9 to complete the welding. The first direction and the second direction are orthogonal. Because the first direction and the second direction are orthogonal, the automated welding production line for welding brackets in this application is not a conventional straight line but has angles, thus occupying a smaller space. The movable work platforms 1 are moved in the first direction by the transfer mechanism 2, and driven in the second direction by the wheel transmission mechanism 3. Using two mechanisms to drive the movable work platforms 1 allows the movable work platforms 1 to move normally even at orthogonal points. The welding robotic arm 4 can automatically weld the brackets on the mobile work platform 1. The mobile work platform 1 moves in a fixed order between the loading station 5, the pre-assembly station 6, the welding station 7, the quality inspection station 8, and the unloading station 9 to form a cycle, thereby speeding up the welding efficiency of the brackets.

[0031] In summary, compared with existing technologies, by using the combination of the transfer mechanism 2, the welding robotic arm 4, the wheel transmission mechanism 3 and the mobile work platform 1, automated welding work can be achieved. Multiple mobile work platforms 1 can accelerate welding efficiency and save labor.

[0032] Preferably, the welding robotic arm 4 includes a base, an upper arm, a forearm, a wrist, and a welding torch. The bottom of the base is fixedly mounted on the welding station 7, and the top of the base is rotatably connected to one end of the upper arm. The other end of the upper arm is rotatably connected to one end of the forearm, and the other end of the forearm is rotatably connected to one end of the wrist. The other end of the wrist is fixedly connected to the welding torch. The welding robotic arm 4 typically adopts a multi-axis articulated design and performs welding through the welding torch at its end. The upper arm, forearm, and wrist can achieve precise welding. The connection between the base and the upper arm uses a worm gear and crossed roller bearing to achieve a wide range of horizontal rotation, while the connection between the upper arm and the forearm uses a servo motor 32 and a harmonic reducer to achieve high-precision vertical movement. The connection between the forearm and the wrist uses a compact planetary gear and a magnetic encoder to achieve fine-tuning of the end-effector posture.

[0033] Preferably, the welding robotic arm 4 is also equipped with a control system for controlling its operation. A vision sensor is mounted on the wrist for weld seam identification, positioning, and tracking. The vision sensor and control system are electrically connected to receive information from the vision sensor and complete the welding of the support. The control system typically consists of a host computer, a motion controller, a communication module, and an actuator. The host computer is responsible for path planning and data processing, the motion controller controls the joint movement of the robotic arm through real-time algorithms, the communication module transmits signals, the actuator directly drives the specific structure, and the vision sensor receives external images, which are then processed by the control system to generate coordinates, and the specific welding position is then located. In this embodiment, the control system obtains the images transmitted by the vision sensor, processes them, and then drives the welding robotic arm 4 to achieve automatic welding.

[0034] Preferably, the transfer mechanism 2 includes a transfer track 22 and a liftable transfer vehicle 21 that moves on the transfer track 22. When the transfer mechanism 2 moves the movable work platform 1 along a first direction, the movable work platform 1 is placed on the liftable transfer vehicle 21, and the liftable transfer vehicle 21 is in a raised state. The transfer mechanism 2 is an automated device for transferring materials between different heights or positions. In this embodiment, the liftable transfer vehicle 21 can abut against the movable work platform 1 by raising its own height, thereby driving the movable work platform 1 to move. When the liftable transfer vehicle 21 lowers its own height, it can disengage from the movable work platform 1.

[0035] Preferably, the wheel transmission mechanism 3 includes: multiple support seats 33 spaced apart on the loading station 5, pre-assembly station 6, welding station 7, quality inspection station 8, and unloading station 9; rollers 31 and a motor 32 disposed on the top of the support seats 33 to provide transmission support for the movable work platform 1. When the wheel transmission mechanism 3 moves the movable work platform 1 along the second direction, the liftable shuttle 21 is in a lowered state, and the rollers 31 support and transport the movable work platform 1. Support bases 33 are arranged at certain intervals and in a certain order on the loading station 5, pre-assembly station 6, welding station 7, quality inspection station 8 and unloading station 9. The output shaft of the motor 32 is engaged with the roller 31. Therefore, when the movable work platform 1 moves along the second direction, the movable work platform 1 abuts against the roller 31. The roller 31 rotates under the drive of the motor 32. Therefore, the movable work platform 1 can move under the drive of the roller 31. Moreover, the wheel transmission mechanism 3 and the transfer mechanism 2 work together to enable the movable work platform 1 to make right-angle turns.

[0036] Preferably, the automated welding production line for welding brackets further includes a table 10, on which a welding robotic arm 4, a support base 33, and a transfer track 22 are fixedly mounted. The support base 33, the base, and the transfer track 22 are fixedly connected to the table 10 by welding, screwing, or riveting. In this embodiment, the support base 33 is screwed to the table 10 through a through hole, and the speed of movement of the movable work platform 1 is controlled by a motor 32 driving the rollers 31. More preferably, the base of the welding robotic arm 4 is a sliding track parallel to both sides of the welding station 7, allowing the welding robotic arm 4 to slide on the sliding track, thereby expanding the weldable area and enabling more flexible and efficient welding of the bracket.

[0037] Preferably, the movable work platform 1 is a three-dimensional flexible assembly platform. This platform has several regularly arranged through holes for quick fixing of the bracket to be welded via pin connections. The three-dimensional flexible assembly platform is a modular, high-precision tooling system. Through the combination of a standardized hole system and quick-locking pins, it achieves precise positioning and flexible clamping of the bracket. The through holes on the three-dimensional flexible assembly platform provide convenient connection points when expanding components. For example, a fixture can be installed at the pre-assembly station 6 to fix the bracket parts, facilitating installation. Furthermore, it allows for the direct pre-fixation of some bracket parts. Since the through holes are arranged at fixed intervals, bracket parts of the same size are also in the same position, enabling pre-fixation of bracket parts on the movable work platform 1 and increasing the speed of bracket pre-assembly.

[0038] Preferably, the transfer mechanism 2 is configured to move the movable work platform 1 between the loading station 5 and the pre-assembly station 6, and between the quality inspection station 8 and the unloading station 9. Therefore, the first direction is between the loading station 5 and the pre-assembly station 6, and between the quality inspection station 8 and the unloading station 9, and the transfer mechanism 2 moves from the loading station 5 to the pre-assembly station 6, and from the quality inspection station 8 to the unloading station 9.

[0039] Preferably, the wheel transmission mechanism 3 is configured to move the movable work platform 1 between the pre-assembly station 6, the welding station 7, the quality inspection station 8, the unloading station 9, and the loading station 5. Therefore, the second direction is between the pre-assembly station 6, the welding station 7, the quality inspection station 8, the unloading station 9, and the loading station 5, and the movement direction of the wheel transmission mechanism 3 is from the pre-assembly station 6 to the welding station 7, from the welding station 7 to the quality inspection station 8, and from the unloading station 9 to the loading station 5.

[0040] Preferably, the movable work platform 1 moves sequentially along the loading station 5, pre-assembly station 6, welding station 7, quality inspection station 8, and unloading station 9, forming a closed rectangle along the displacement path. The automated welding production line for welding brackets is specifically rectangular in shape, and the movable work platform 1 can also move along the rectangular path. Therefore, this automated welding production line for welding brackets occupies relatively little space, and the movable work platform 1 can form a cycle by moving along the rectangular path, resulting in higher production efficiency.

[0041] Specifically, the workflow of this embodiment is as follows: The parts to be welded are placed on the loading station 5, and then the transfer mechanism 2 moves them to the pre-assembly station 6. The bracket to be welded is pre-fixed and shaped on the pre-assembly station 6. After completion, the wheel transmission mechanism 3 moves it to the welding station 7. The welding robot arm 4 performs automated welding on the bracket to be welded. After welding, the wheel transmission mechanism 3 moves the bracket to the quality inspection station 8. The quality inspection station 8 is used to inspect the welded bracket. After the quality inspection, the transfer mechanism 2 moves the bracket to the unloading station 9. The bracket is hoisted and moved away on the unloading station 9. The wheel transmission mechanism 3 then moves it back to the loading station 5 on the unloading station 9 to start automated welding of the bracket.

[0042] Example 2:

[0043] Reference Figure 4 The difference between this embodiment and the previous embodiment is that four welding robotic arms 4 are placed on the welding station 7, as detailed below.

[0044] In this embodiment, welding robotic arms 4 are installed on both sides of the welding station 7 to perform the welding work on the bracket to be welded. By increasing the number of welding robotic arms 4, the welding speed is increased and the welding efficiency is accelerated.
