This severely impacts the continuity of welding operations, resulting in relatively low welding efficiency. Furthermore, the fixed loading and welding distances during the welding process make it difficult to adjust them flexibly according to actual production needs, further restricting the efficiency and flexibility of welding production.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Figure 1 This is a schematic diagram of the structure of an automatic welding feeding device according to the present invention; Figure 2 This is a schematic diagram of the drive assembly of an automatic welding feeding device according to the present invention; Figure 3This is a schematic diagram of the sliding component of an automatic welding loading device according to the present invention. It shows an automatic welding loading device of a preferred embodiment, which is located between a loading robot 5 and a welding robot 7. It includes a support frame 1, a welding frame 2, two welding platforms 3 and two drive components 4. The welding frame 2 is mounted on the support frame 1. The two welding platforms 3 are located on both sides of the welding frame 2 and can slide closer to or away from the loading robot 5 / welding robot 7. Each welding platform 3 has a plurality of positioning elements arranged in an array to position a plurality of workpieces 9. The two drive components 4 are mounted on the welding frame 2 and are respectively connected to the two welding platforms 3 for driving the two welding platforms 3 to slide closer to or away from the loading robot 5 / welding robot 7.

[0033] In this application, by setting up two welding platforms 3, each of which can independently slide closer to or further away from the loading robot 5 and the welding robot 7, the number of workpieces 9 that can be placed is increased, the loading frequency is reduced, and the welding efficiency is improved. On the other hand, the distance between the welding platform 3 and the robot can be flexibly adjusted according to actual needs, which solves the problem of insufficient loading distance and welding distance, and enhances the applicability and flexibility of the device.

[0034] Furthermore, as a preferred embodiment, each positioning component includes two positioning pins 31, which respectively engage with two mounting holes on the workpiece 9. By using the two positioning pins 31 to engage with the mounting holes on the workpiece 9, precise positioning of the workpiece 9 can be achieved, ensuring that the workpiece 9 is accurately positioned on the welding platform 3, thereby improving welding quality and reducing welding defects caused by positional deviations of the workpiece 9.

[0035] Furthermore, as a preferred embodiment, the welding platform 3 is slidably mounted on the welding frame 2 by a plurality of sliding components 10, which are equally spaced along the length of the welding platform 3. The equally spaced sliding components 10 ensure uniform force distribution on the welding platform 3 during sliding, guaranteeing smoothness and stability, preventing issues with workpiece 9 positioning accuracy and welding quality due to uneven sliding, and also helping to extend the service life of the device.

[0036] Furthermore, as a preferred embodiment, each sliding component 10 includes a slide table 101 and a slide rail 102. The slide table 101 is connected to the bottom of the welding platform 3, and the slide rail 102 is mounted on the welding frame 2. The slide table 101 is slidably mounted on the slide rail 102. The cooperation structure between the slide table 101 and the slide rail 102 is simple and reliable, enabling precise sliding of the welding platform 3 on the welding frame 2. This structure also has a high load-bearing capacity, can adapt to the placement and sliding requirements of workpieces 9 of different weights, and is easy to install and maintain.

[0037] Furthermore, in a preferred embodiment, each drive assembly 4 includes a connecting plate 42 and several telescopic cylinders 41. The connecting plate 42 is connected to one side of the slide table 101, and the several telescopic cylinders 41 are respectively mounted on the welding frame 2 and are evenly spaced along the length of the connecting plate 42. The output end of each telescopic cylinder 41 is connected to the connecting plate 42. By concentrating the output force of the multiple telescopic cylinders 41 to the slide table 101 through the connecting plate 42, sufficient driving force can be provided to make the welding platform 3 slide smoothly. The evenly spaced telescopic cylinders 41 can ensure that the connecting plate 42 is subjected to uniform force, further improving the stability and reliability of the sliding of the welding platform 3, while also facilitating the adjustment of the driving force according to actual needs.

[0038] Furthermore, in a preferred embodiment, each drive assembly 4 also includes a plurality of abutment cylinders 43. The plurality of abutment cylinders 43 and the plurality of telescopic cylinders 41 are respectively located on both sides of the welding platform 3, and the plurality of abutment cylinders 43 are all mounted on the welding frame 2. The output end of each abutment cylinder 43 is connected to an abutment block 44, and the abutment block 44 always abuts against the connecting plate 42. The abutment cylinders 43 and the abutment blocks 44 can provide a reverse abutment force during the sliding process of the welding platform 3, playing a role in buffering and stabilizing, preventing the welding platform 3 from generating excessive impact or shaking under the drive of the telescopic cylinders 41, further improving the smoothness of the sliding of the welding platform 3, and ensuring the positional accuracy of the workpiece 9 during the sliding process.

[0039] Furthermore, as a preferred embodiment, a limiting plate 20 is provided between the two connecting plates 42, and the two sides of the limiting plate 20 can respectively limit and cooperate with the two connecting plates 42. The setting of the limiting plate 20 can limit the sliding stroke of the two welding platforms 3, prevent the welding platform 3 from colliding with other components due to excessive sliding, and play the role of a protective device; at the same time, by reasonably setting the position of the limiting plate 20, the distance between the welding platform 3 and the loading robot 5 and the welding robot 7 can be precisely controlled, ensuring the accuracy of loading and welding operations.

[0040] Furthermore, as a preferred embodiment, both the loading robot 5 and the welding robot 7 are six-axis robots. The loading robot 5 has a gripper 6 at its execution end, and the welding robot 7 has a welding torch 8 at its execution end.

[0041] Furthermore, as a preferred embodiment, the gripper 6 is a pneumatic gripper 6. The pneumatic gripper 6 has advantages such as simple structure, fast response speed, and adjustable clamping force, enabling it to quickly and accurately grasp and release the workpiece 9, improving loading efficiency. At the same time, the pneumatic gripper 6 has relatively low cost, is easy to maintain and service, and is suitable for widespread application in industrial production.

[0042] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
