The above diagram is only to show the structural relationship related to the invention point, and is not the actual proportion of the actual product.

[0038] As Figures 1 to 4As shown, the welding positioning equipment includes a positioning device 1 and a floor grabbing device 2. The positioning device 1 is provided with a frame positioning part 3 and a grabbing device positioning part 4. The frame positioning part 3 is used to fix the to-be-welded frame. The floor grabbing device 2 is provided with a limiting part 21, and the limiting part 21 is matched with the grabbing device positioning part 4. The floor grabbing device 2 is used to grab the to-be-welded floor. After the limiting part 21 is matched with the grabbing device positioning part 4, the to-be-welded frame and the to-be-welded floor are assembled together.

[0039] The positioning device 1 is one of the core components in the welding positioning equipment, which mainly includes the following parts:

[0040] Frame positioning part 3: used to fix the to-be-welded frame. This part may include clamps, claws or other forms of fixing mechanisms to ensure that the frame remains stable during assembly.

[0041] Grabbing device positioning part 4: matched with the limiting part 21 on the floor grabbing device 2 to guide and fix the position of the floor grabbing device 2. This can be one or more positioning holes, guide rails or other forms of interface structures.

[0042] The design of the positioning device 1 aims to provide extremely high positioning accuracy, ensuring accurate alignment between the frame and the floor every time. By using high-strength materials and combining with stable support structures, good stability can be maintained even when handling heavy or large-sized parts.

[0043] The to-be-welded frame is firmly fixed in the specified position by the frame positioning part 3; at the same time, the to-be-welded floor is precisely placed in the predetermined position by the cooperation of the grabbing device positioning part 4 and the limiting part 21 on the floor grabbing device 2. This simplifies the traditional manual adjustment process, reduces errors caused by human factors and speeds up the entire assembly process. Precise positioning helps to avoid welding defects caused by positional deviation, thereby improving the quality and consistency of the final product. The improvement of automation reduces the opportunity for workers to directly contact heavy components, reducing the safety risk of the workplace.

[0044] In one embodiment, the positioning device 1 is a three-dimensional positioning device 11. Specifically, the positioning device 1 is in a rectangular form.

[0045] The positioning device 1 is a three-dimensional positioning device 11, which means it can accurately adjust the workpiece in X, Y and Z directions. Specifically, each positioning device 1 may include the following parts:

[0046] Base: provides stable basic support.

[0047] Mobile platform: Can move along X-axis (horizontal lateral), Y-axis (horizontal longitudinal) and Z-axis (vertical direction).

[0048] Drive system: Includes motors, lead screws, guide rails, etc., for precise movement in each axis.

[0049] Sensor and control system: Ensures positioning accuracy, adjusts position deviation through feedback mechanism.

[0050] Through precise adjustment in X, Y, Z three directions, the position of the frame positioning part 3 and the grabbing device positioning part 4 can be fine-tuned from three dimensions, ensuring high-precision assembly. The automated three-dimensional positioning device 11 reduces the need for manual intervention, speeds up the assembly process, and reduces labor intensity. Automated operation reduces the opportunity for workers to directly contact heavy components, improving workplace safety. Reducing position deviation caused by manual operation improves welding quality and consistency of finished products. Easy to integrate into automated production lines, supports remote control and programmed operation, improves production efficiency.

[0051] Adopting a multi-point support method improves the stability of the overall structure, especially suitable for handling large or heavy components. Multiple positioning devices 1 operate in coordination, facilitating flexible configuration as needed.

[0052] Specifically, when the three-dimensional positioning device 11 is distributed as four:

[0053] Layout description: Assuming there is a rectangular work area, four positioning devices 1 will be placed at the four corners of the rectangle. Such a layout allows each positioning device 1 to be responsible for a corner, working together to maintain the balance and stability of the entire structure.

[0054] Function description: Each positioning device 1 can independently move in X, Y, Z three directions, but they also need to cooperate with each other through synchronous control to ensure the correct position of the entire structure. This layout is particularly suitable for situations that require simultaneous fixation and adjustment of large-sized or complex-shaped workpieces.

[0055] In one embodiment, the frame positioning part 3 is a flexible frame positioning part 3.

[0056] The flexible frame positioning part 3 can adapt to different shapes, sizes and structures of the to-be-welded frame, and can automatically adjust to provide the best fixed effect device. Compared with traditional rigid positioning parts, the flexible frame positioning part 3 has higher adaptability and flexibility, and can accurately fix without damaging the surface of the frame.

[0057] The specific structure can include:

[0058] Adjustable clamps: using retractable or rotatable clamps, which can be adjusted according to the specific shape and size of the frame.

[0059] Flexible material: the contact surface of the clamp uses soft and elastic materials (such as rubber, polyurethane, etc.), to reduce the risk of scratching the surface of the frame.

[0060] Sensor system: including pressure sensors, position sensors, etc., for detecting the position and state of the frame, providing real-time feedback to the control system.

[0061] Actuator: such as servo motors, pneumatic or hydraulic drivers, etc., responsible for adjusting the position and force of the clamp according to the instructions of the control system.

[0062] Control system: controller integrated with software algorithms, capable of processing data from sensors and issuing corresponding control signals to actuators, achieving precise positioning and clamping.

[0063] Due to the flexible frame positioning part 3, the production line can more flexibly meet the production needs of different models, reducing downtime caused by changing clamps. The use of flexible materials ensures that the frame surface will not be scratched or damaged during clamping, maintaining the appearance quality of the frame. Through precise sensors and control systems, the frame can be fixed in the best position every time, improving assembly accuracy and consistency. The high degree of automation of the flexible positioning part reduces the dependence on manual skills and reduces the difficulty of operation, making the operation simpler and safer. Precise positioning and appropriate clamping force can effectively reduce welding defects caused by inaccurate positioning, thereby reducing scrap rates. Fast adaptive ability and efficient positioning process significantly shorten the entire assembly cycle, improving the overall efficiency of the production line. The automatic clamping and positioning process reduces the opportunity for workers to directly contact heavy components, reducing the safety risks in the workplace. The application of flexible materials not only protects the frame but also reduces the wear and tear on the positioning device 1 itself, extending the service life of the equipment.

[0064] In summary, the flexible frame positioning part 3, through its unique structural design and intelligent characteristics, not only effectively avoids damage to the frame surface, but also improves assembly accuracy and production efficiency in the automobile manufacturing process, enhances the safety of operation and the flexibility of production, is one of the indispensable key components in modern intelligent manufacturing.

[0067] The gripper 23 is located in the middle of the bracket 22, which can ensure uniform stress during the grabbing of the floor, reducing local pressure on the floor and avoiding damage. The gripper 23 is connected to the bracket 22 through a mechanical or hydraulic system, and can be opened and closed under the command of the control system.

[0068] The limiting part 21 is set on the edge of the bracket 22, which matches the grabbing device positioning part 4 on the positioning device 1. The role of the limiting part 21 is to ensure that the floor grabbing device 2 can accurately dock with the positioning device 1 after moving to the predetermined position, so as to realize the precise assembly of the to-be-welded frame and the to-be-welded floor.

[0069] The bracket 22 is made of high-strength material (such as steel), which ensures stability and durability during long-term use. It is easy to maintain and replace, and the layout can be adjusted according to different sizes of floor. Although sufficient strength is required, the design of the bracket 22 also takes into account the factor of light weight in order to improve operational efficiency. In order to better disperse the weight of the floor, the bracket 22 may be designed with multiple support points to ensure that the floor remains stable during the grabbing process.

[0070] The gripper 23 is made of flexible material (such as rubber, silicone, etc.), which can adapt to different shapes and surface characteristics of the floor while reducing damage to the floor surface. The gripper 23 can be adjusted in opening and closing by the control system to adapt to different sizes of floor. Combined with sensor technology, the gripper 23 ensures accurate positioning during the grabbing process. It has certain self-adaptive ability and can automatically adjust the grabbing force to a certain extent to prevent damage caused by excessive clamping.

[0071] The limiting part 21 has high-precision matching with the grabbing device positioning part 4 on the positioning device 1, ensuring that the floor grabbing device 2 can quickly and accurately dock with the positioning device 1 after moving to the designated position. The limiting part 21 is designed with a quick locking mechanism, which can be quickly fixed once it reaches the specified position, improving work efficiency. The limiting part 21 is usually designed with obvious marks or features for visual recognition or sensor detection, ensuring that the operator or automatic system can accurately determine its position.

[0074] In one embodiment, further comprising an automated guided vehicle 5, which transports the to-be-welded frame to the top of the positioning device 1.

[0075] The main task of the automated guided vehicle 5 (AGV) is to transport the to-be-welded frame from the storage area or the previous process to the top of the positioning device 1 of the welding positioning equipment. AGV achieves autonomous navigation through preset paths, laser navigation, visual navigation, and other technologies, without the need for human intervention.
