Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically to a positioning welding device for electrical equipment. Background Technology

[0002] Welding is a crucial process in electrical equipment manufacturing, connecting various metal components. As electrical equipment evolves towards miniaturization, precision, and integration, the requirements for welding positioning accuracy and automation are constantly increasing. Currently, the positioning welding of electrical equipment components mainly employs the following methods: Manual positioning welding: Operators use clamps or manually clamp the workpiece to perform spot welding or continuous welding. This method is inefficient, the positioning accuracy is greatly affected by human factors, and the welding quality is unstable.

[0003] Semi-automatic welding fixtures: These use pneumatic or manual clamps to position the workpiece, which is then used in conjunction with a welding robot or welding torch for welding. While this improves efficiency to some extent, the clamps have a limited adjustment range and are difficult to adapt to workpieces of different shapes and sizes.

[0004] Conveyor belt welding: Workpieces are placed on a conveyor belt and pass through the welding stations one by one. However, workpieces are prone to shifting during the conveying process, and the lack of effective lateral positioning and clamping mechanisms affects welding accuracy.

[0005] Existing technologies generally suffer from the following shortcomings: Inaccurate positioning: Electrical equipment housings, mounting plates and other components have various shapes and surfaces that may be uneven or curved, making it difficult for traditional clamps to achieve tight fit and reliable positioning.

[0006] Poor adaptability: Different specifications of electrical equipment require different fixtures, the changeover time is long, and it is difficult to adapt to multi-variety small-batch production.

[0007] Separation of conveying and positioning: The conveying mechanism is only responsible for conveying, and an additional positioning device is required during welding, resulting in a lack of smooth process connection.

[0008] Inconvenient welding angle adjustment: Welding guns are usually fixed, making it difficult to achieve flexible welding at multiple angles and positions, and complex welds require multiple clamping operations.

[0009] Low level of automation: There is a lack of linkage control between various processes, which relies on manual intervention and affects production efficiency and consistency.

[0010] Therefore, there is an urgent need for an electrical equipment positioning and welding device that can achieve automatic workpiece conveying, flexible positioning, multi-angle welding, and strong adaptability. Summary of the Invention

A slide rod is fixedly connected to the side of the elastic element fixing plate near the second elastic element. The slide rod passes through the cylinder and is slidably connected to the cylinder. A low-damping locking block is fixedly connected to one end of the slide rod located outside the cylinder.

[0021] The present invention has the following advantages: 1. Flexible positioning and strong adaptability: Two electromagnetic suction belts are respectively located on both sides of the moving conveyor mechanism, using electromagnetic attraction to laterally attract and position the workpiece. The spacing of the electromagnetic suction belts can be adjusted according to the workpiece width via a spacing adjustment mechanism to accommodate workpieces of different sizes. The flexible material of the electromagnetic suction belts can conform to the workpiece surface, achieving good contact even with slight unevenness, providing uniform adsorption force.

[0022] 2. Adaptive Clamping and Reliable Positioning: The clamping positioning mechanism is located inside the electromagnetic attraction belt. Its low-damping clamps can extend and retract radially under the action of the second elastic element. When the workpiece is conveyed to the clamping position, the clamps automatically adjust their position according to the outer contour of the workpiece, providing auxiliary clamping and positioning to prevent the workpiece from shifting during welding. Multiple clamps are arranged circumferentially to accommodate workpieces of different shapes, such as round and square.

[0023] 3. Integrated conveying and positioning for smooth operation: The mobile conveyor mechanism drives the workpiece to be continuously conveyed forward. The electromagnetic suction belt and the clamping block positioning mechanism can complete the lateral and longitudinal positioning of the workpiece during the conveying process, eliminating the need for a separate positioning station and improving production efficiency.

[0024] 4. Flexible and adjustable welding angle with a wide coverage: The positional welding mechanism uses a first motor to drive the entire positioner frame to rotate, achieving horizontal rotation of the welding gun; a second motor drives two positioner blocks to move in opposite directions, causing the welding gun to move laterally; and a linear motor achieves the lifting and lowering of the welding gun. This multi-degree-of-freedom adjustment allows the welding gun to reach any position on the workpiece surface and perform welding at the optimal angle.

[0025] 5. Adjustable tension of the electromagnetic attraction belt and stable transmission: The elastic displacement synchronous pulley mechanism uses a first elastic element to keep the second synchronous pulley taut, ensuring that the electromagnetic attraction belt is always at the appropriate tension and preventing slippage or loosening. The conductive contact point supplies power to the electromagnetic attraction belt through the second synchronous pulley, achieving simultaneous conveying and attraction, with a compact structure.

[0026] 6. Synchronous drive, coordinated operation on both sides: The conveyor drive mechanism simultaneously drives the active synchronous wheel mechanisms on both sides through the drive shaft, ensuring that the two electromagnetic attraction belts operate synchronously and preventing workpiece deviation. The drive groove on the drive shaft cooperates with the drive bar inside the rotating sleeve, allowing the drive shaft to still transmit torque when the displacement frame is adjusted in spacing.

Multiple clamping blocks are arranged circumferentially to accommodate workpieces of different shapes such as round and square.

[0048] The workflow of this invention is as follows: Width adjustment: Based on the workpiece width, start the fourth motor 502 and adjust the distance between the two displacement frames 6 so that the distance between the electromagnetic attraction belts 10 is slightly greater than the workpiece width.

[0049] Workpiece conveying: Place the workpiece on the conveyor belt 403, start the third motor 404, and the conveyor belt 403 will drive the workpiece forward.

[0050] Adsorption and positioning: The fifth motor 702 is started, driving the drive shaft 703 to rotate, which in turn drives the electromagnetic attraction belt 10 to rotate through the active synchronous wheel mechanism 8. The electromagnetic attraction belt 10 generates magnetism when energized, attracting the workpiece from both sides and keeping the workpiece in a centered position during the conveying process.

[0051] Assisted positioning by clamping block: When the workpiece passes through the clamping block positioning mechanism 11, the fourth motor 502 is further activated to adjust the distance between the two displacement frames 6. Under the action of the second elastic element 1103, the low-damping clamping block 1106 makes the electromagnetic suction band 10 in close contact with the surface of the workpiece, providing auxiliary clamping and preventing the workpiece from moving during welding.

[0052] Welding operation: After the vision sensor identifies the weld position, the control system controls the first motor 301, the second motor 304 and the linear motor 308 to move the welding gun 309 to the weld position and perform welding at the optimal angle.

[0053] Material discharge: After welding is completed, the workpiece continues to move forward with the conveyor belt 403 and enters the next process or collection area.
