[0022] 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.

[0023] A flexible welding assembly workstation, such as Figure 1 - Figure 5As shown, the system includes a frame 1, with a support frame 2 slidably mounted on top of the frame 1. Horizontal guide rails 8 are provided on both sides of the frame 1, and the horizontal guide rails 8 are fixed to the mounting surface by fasteners. The support frame 2 is slidably connected to the horizontal guide rails 8. Two mounting brackets 3 are fixedly mounted on the support frame 2, and welding robots 4 are slidably mounted on the mounting brackets 3. The welding robots 4 are electrically connected to an external controller and are driven by electric cylinders, which are also electrically connected to the external controller. A drive assembly is provided on the frame 1, which can drive the support frame 2 to move laterally. A welding station platform 1 (first welding station platform 5) is provided on the frame 1 and fixed to the frame 1 by fasteners. A second welding station platform 6 is also provided on the frame 1 and fixed to the frame 1 by fasteners. Workpiece clamps 7 are provided on both welding station platforms 1 and 2, and the workpiece clamps 7 are fixed to both welding station platforms 1 and 2 by fasteners. The support frame 2 is fixed, and the workpiece clamp 7 can be changed according to the workpiece to be clamped. The support frame 2 is equipped with a detection component, which can detect whether the workpiece is correctly placed when welding. By setting up two welding stations, welding station 1 5 and welding station 2 6, different types of workpieces can be welded on welding station 1 5 and welding station 2 6. When a complete workpiece needs to be welded and assembled multiple times, and the assembly material type and welding method required are different, the welding routes of two sets of welding robots 4 are set according to the different types of workpieces to be welded, and the welding methods (such as self-fusion welding and filler wire welding) are set according to different welding requirements and material types to improve the versatility of the production line. At the same time, the detection component is set up so that when the workpiece to be welded is placed on welding station 1 5 and welding station 2 6, the detection component can detect whether the workpiece is correctly placed to ensure the welding effect.

[0024] Furthermore, the drive assembly includes a drive rack 9, which is fixedly mounted on the frame 1. A movable frame 10 is slidably mounted on the frame 1, and a drive gear 11 is rotatably mounted on the movable frame 10. The drive gear 11 is driven by a servo motor, which is electrically connected to an external controller. The drive gear 11 meshes with the drive rack 9. A connecting frame 12 is slidably mounted on the frame 1 and is fixedly connected to the movable frame 10. When the movable frame 10 slides, it can drive the connecting frame 12 to slide synchronously. Both ends of the connecting frame 12 are fixedly connected to the inner walls of the support frame 2. By providing the drive assembly, welding of different types of workpieces can be performed on welding station 5 and welding station 6. When a complete workpiece needs to be welded multiple times... When assembling different types of materials and welding methods, two sets of welding robots 4 are set according to the different types of workpieces to be welded. Welding of different types of workpieces is performed on welding station 1 5 and welding station 2 6. After the workpiece is welded on welding station 1 5, it can be transferred to welding station 2 6. Then, by controlling the drive gear 11 to rotate and cooperating with the drive rack 9 to drive the support frame 2 to move laterally, the welding robot 4 is switched to the corresponding welding station 2 6. At this time, another welding robot 4 can be used to complete the second welding assembly operation of the workpiece on welding station 2 6, thereby improving the versatility of the production line and improving the overall assembly efficiency of the workpiece.

[0025] Furthermore, the detection component includes a fixed top seat 13, which is fixedly mounted on the support frame 2. A positioning turntable 14 is rotatably mounted on the bottom of the fixed top seat 13. The positioning turntable 14 is driven by a servo motor, which is electrically connected to an external controller. A mounting base 16 is provided at the bottom of the positioning turntable 14, and the mounting base 16 is fixed to the positioning turntable 14 by fasteners. The position of the mounting base 16 is flexibly adjustable. An extension arm 15 is movably mounted on the bottom of the mounting base 16. The extension arm 15 is driven by an electric cylinder, which is electrically connected to the external controller. The extension arm 15 can perform vertical linear motion under the mounting base 16. A point contact 20 is slidably mounted inside the extension arm 15. A contact sensor 19 is fixedly mounted inside the extension arm 15 and is electrically connected to the external controller. One end of the point contact 20 extends into the extension arm 15 and is fixedly mounted. The extension arm 15 is equipped with a pressure contact 17 and a spring 18 is fixedly installed inside it. One end of the spring 18 is fixedly connected to the point contact 20. By setting a detection component, during the welding process, the standard placement position of the workpiece is set and the fixed descent distance of the extension arm 15 at the fixed point is set. When welding, if the workpiece is correctly placed, the contact sensor 19 can send a contact signal to the system when the extension arm 15 descends to the fixed point. This indicates that the workpiece is correctly placed at that point. During detection, multi-point detection of the workpiece is set. By controlling the extension arm 15 to rotate to different set points on the corresponding workpiece and descending a set distance, if the system can receive the contact signal in multiple tests, it indicates that the workpiece is correctly placed and welding can be performed. If the workpiece is not correctly placed, the system prompts manual adjustment before welding to ensure the subsequent welding effect.

[0026] Working principle: During welding, the workpiece is fixed on welding station 5 and welding station 6 by workpiece clamp 7. The welding robot 4 can automatically weld the workpiece. The welding method of the welding robot 4 can be switched according to different types of workpiece materials and welding requirements, and the welding route can be set.

[0027] If a complete workpiece requires multiple welding assemblies, and the material type and welding method are different for each welding assembly, different welding routes and welding methods are set for two welding robots 4. The workpiece is placed on welding station 5, and the first welding robot 4 is controlled to perform the welding assembly operation of the first material on welding station 5. After the first welding is completed, the workpiece is removed and fixed on welding station 6. The servo motor drives the drive gear 11 to rotate and cooperates with the drive rack 9 to drive the support frame 2 to move laterally until the support frame 2 is switched to the corresponding welding station 6. At this time, the second welding robot 4 can be used to complete the second welding assembly operation of the second material on welding station 6. After the welding is completed, the workpiece can be removed for subsequent processing operations.

[0028] During the welding process, a standard workpiece placement position is set, and the position of the extension arm 15 is adjusted. The extension arm 15 is adjusted to a fixed position, and a fixed distance is set for the workpiece to descend to a certain point corresponding to the extension arm 15. When the workpiece is manually placed on welding station 5 and welding station 6, if the workpiece is correctly placed, the point contact 20 can contact the fixed point on the workpiece when the extension arm 15 is driven by the electric cylinder to descend to the fixed position. The point contact 20 is then pressed and slides inward on the extension arm 15, causing the pressure contact 17 to contact the contact sensor 19. When the system receives a contact signal, it indicates that the workpiece is correctly placed. During detection, multi-point detection of the workpiece is set. The servo motor drives the adjustment turntable 14 to rotate the extension arm 15 to different set points on the corresponding workpiece and descend a set distance. If the system can receive a contact signal in multiple tests, it indicates that the workpiece is correctly placed and welding can be performed. If the workpiece is not correctly placed, the system prompts the operator to adjust it before welding.
