Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, and in particular to a fully automatic point-to-point multi-unit welding robotic arm. Background Technology

[0002] The fully automated multi-unit welding robotic arm can operate in tandem with multiple machines, eliminating the need for manual point-to-point alignment, significantly shortening the welding cycle, and adapting to the needs of mass production. Through precise positioning technology, it achieves millimeter-level point-to-point accuracy, avoiding errors from manual operation, ensuring uniform welds and stable strength, and replacing manual labor in welding work in harsh environments such as high temperature and dust, reducing reliance on skilled workers, and avoiding the risk of workplace injuries.

[0003] In existing fully automated point-to-point multi-unit welding robotic arms, sparks are easily generated during the welding process. High-temperature sparks may burn on-site personnel. If there are flammable materials such as oil stains and packaging materials in the workshop, it is very easy to cause a fire. At the same time, sparks are often accompanied by the spread of welding fumes, which pollute the workshop environment. Long-term exposure to an environment without proper protection can also endanger the respiratory health of operators. Therefore, a fully automated point-to-point multi-unit welding robotic arm is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fully automatic point-to-point multi-unit welding robotic arm, which has the advantage of solving the problem of sparks flying during the welding process and thus solves the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a fully automatic point-to-point multi-unit welding robotic arm, including a robotic arm, one end of which is fixedly connected to a connecting shaft, one end of which is provided with a welding head, two sets of positioning plates are mounted on the surface of the connecting shaft, a circular block is fixedly connected to one side of the two sets of positioning plates, a fixing ring is provided on one side of the circular block, a locking block is fixedly connected to the inner wall of the fixing ring, a protrusion is engaged inside the fixing ring, a dustproof box is fixedly connected to one side of the protrusion, and the dustproof box is sleeved on the outside of the welding head.

[0006] Preferably, the inner wall of the robotic arm is equipped with multiple sets of U-shaped frames, one end of which is fixedly connected to a load-bearing frame, one end of which is fixedly connected to the bottom wall of the robotic arm, an arc-shaped block is slidably connected inside the U-shaped frame, one end of which is fixedly connected to a threaded rod, and two sets of triangular plates are slidably connected to the other end of the U-shaped frame.

[0007] Preferably, a slot is provided on the other side of the two sets of positioning plates, and a retaining shaft is engaged with the inner wall of the slot, with one end of the retaining shaft penetrating into the interior of the connecting shaft.

[0008] Preferably, a limiting ring is provided on one side of the circular block, and one end of the fixing ring is fixedly connected to the inside of the limiting ring.

[0009] Preferably, the surface of the connecting shaft is provided with a keyway, and the retaining shaft is disposed inside the keyway.

[0010] Preferably, the U-shaped frame has grooves on both sides, and the two ends of the arc-shaped block are fixedly connected to sliders, which slide inside the grooves.

[0011] Preferably, a protective pad is attached to the other end of the arc-shaped block.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model uses a connecting shaft to connect the robotic arm and the welding head together, and uses a positioning plate to provide an installation base for the circular block. Then, under the action of the fixing ring, the fixing ring can be installed on the inner wall of the positioning plate. Next, the dust box can be inserted into the inside of the fixing ring through the protrusion, and then rotated to engage with the locking block, so as to prevent the dust box from shifting or falling off during use. Using the dust box reduces the range of spark splashing and prevents sparks from spreading to surrounding equipment or flammable materials, thereby reducing the risk of fire and burns to personnel.

[0013] 2. This utility model allows for the classification of different circuits inside the robotic arm by placing them inside the U-shaped frame, facilitating subsequent maintenance. Under the action of the load-bearing frame, the load-bearing capacity of the structure can be improved. When the circuits inside the robotic arm fall into the U-shaped frame, they will contact the arc-shaped block and, in conjunction with the use of the triangular plate, limit the circuits. Then, rotating the threaded rod can adjust the height of the arc-shaped block, thereby changing the height of the circuits for easier subsequent use. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 The fully automatic point-to-point multi-unit welding robotic arm includes a robotic arm 1. A connecting shaft 2 is fixedly connected to one end of the robotic arm 1. A welding head 6 is installed at one end of the connecting shaft 2. Two sets of positioning plates 4 are mounted on the surface of the connecting shaft 2. A circular block 504 is fixedly connected to one side of each of the two sets of positioning plates 4. A fixing ring 502 is provided on one side of the circular block 504. A locking block 503 is fixedly connected to the inner wall of the fixing ring 502. A protrusion 501 is engaged inside the fixing ring 502. A dustproof box 5 is fixedly connected to one side of the protrusion 501. The dustproof box 5 is fitted over the welding head 6. The welding head 6 is connected via a connecting shaft 2. The connecting shaft 2 can connect the robotic arm 1 and the welding head 6 together, and the positioning plate 4 provides a mounting base for the circular block 504. Then, under the action of the fixing ring 502, the fixing ring 502 can be installed on the inner wall of the positioning plate 4. Next, the dust box 5 can be inserted into the inside of the fixing ring 502 through the protrusion 501, and then rotated to engage with the locking block 503, so as to prevent the dust box 5 from shifting or falling off during use. The dust box 5 reduces the range of sparks splashing and prevents sparks from spreading to surrounding equipment or flammable materials, thereby reducing the risk of fire and burns to personnel.

[0018] Please see Figure 1 , Figure 2 and Figure 4Multiple U-shaped frames 7 are installed on the inner wall of the robotic arm 1. One end of each U-shaped frame 7 is fixedly connected to a load-bearing frame 701, and the other end of the load-bearing frame 701 is fixedly connected to the bottom wall of the robotic arm 1. An arc-shaped block 703 is slidably connected inside the U-shaped frame 7. One end of the arc-shaped block 703 is fixedly connected to a threaded rod 705, and the other end of the U-shaped frame 7 is slidably connected to two sets of triangular plates 706. By placing different wires inside the robotic arm 1 inside the U-shaped frame 7, they can be classified for easy maintenance. Under the action of the load-bearing frame 701, the load-bearing capacity of the structure can be improved. When the wires inside the robotic arm 1 fall into the U-shaped frame 7, they will contact the arc-shaped block 703 and, in conjunction with the use of the triangular plates 706, limit the wires. Then, rotating the threaded rod 705 can adjust the height of the arc-shaped block 703, thereby changing the height of the wires for easy use later.

[0019] Please see Figure 1 and Figure 5 On the other side of the two sets of positioning plates 4, there is a slot 401. The inner wall of the slot 401 is engaged with a retaining shaft 402. One end of the retaining shaft 402 extends into the interior of the connecting shaft 2. By using the slot 401 and the retaining shaft 402, the positioning plates 4 are prevented from loosening or shifting due to surface mounting alone. The two sets of positioning plates 4 are firmly locked in the preset position of the connecting shaft 2, providing a foundation for the stable installation of the dust box 5 and preventing the dust box 5 from detaching from the welding head 6 due to the displacement of the positioning plates 4.

[0020] Please see Figure 1 and Figure 3 A limiting ring 505 is provided on one side of the circular block 504. One end of the fixing ring 502 is fixedly connected to the inside of the limiting ring 505. The limiting ring 505 is essentially a ring-shaped limiting structure. By fixing one end of the fixing ring 502 inside it, the installation position of the fixing ring 502 on the circular block 504 can be quickly determined.

[0021] Please see Figure 1 and Figure 2 The surface of the connecting shaft 2 is provided with a keyway 201, and the retaining shaft 402 is disposed inside the keyway 201. The keyway 201 provides a mounting slot for the retaining shaft 402 that fits its shape, which can precisely limit the circumferential rotation and radial offset of the retaining shaft 402.

[0022] Please see Figure 2 and Figure 4 The U-shaped frame 7 has sliding grooves 702 on both sides, and the two ends of the arc block 703 are fixedly connected to sliders 704, which slide inside the sliding grooves 702.

[0023] The groove 702 provides a matching sliding track for the slider 704, which can strictly limit the movement direction of the slider 704, thereby constraining the movement trajectory of the arc block 703. Since one end of the arc block 703 is connected to the threaded rod 705, when the threaded rod 705 is driven, the slider 704 slides along the groove 702 to avoid the arc block 703 from deviating or twisting, ensuring that the arc block 703 always moves smoothly in the preset direction.

[0024] Please see Figure 2 and Figure 4 The other end of the arc-shaped block 703 is attached with a protective pad. By using the protective pad, the arc-shaped block 703 can be prevented from directly contacting the circuit, thus preventing the circuit from being scratched.

[0025] Working principle: The robotic arm 1 and welding head 6 can be connected together using the connecting shaft 2, and the positioning plate 4 provides the mounting base for the circular block 504. Then, under the action of the fixing ring 502, the fixing ring 502 can be installed on the inner wall of the positioning plate 4. Next, the dust box 5 can be inserted into the inside of the fixing ring 502 through the protrusion 501, and then rotated to engage with the locking block 503, preventing the dust box 5 from shifting or falling off during use. The dust box 5 reduces the range of sparks splashing, preventing sparks from spreading to surrounding equipment or flammable materials, reducing the risk of fire and burns. Different wires inside the robotic arm 1 are placed inside the U-shaped frame 7, which can classify them for easy maintenance later. Under the action of the load-bearing frame 701, the load-bearing capacity of the structure can be improved. When the wires inside the robotic arm 1 fall into the U-shaped frame 7, they will contact the arc block 703 and, with the use of the triangular plate 706, limit the wires. Then, rotating the threaded rod 705 can adjust the height of the arc block 703, thereby changing the height of the wires for easy use later.
