[0025] The quick-release assembly 70 facilitates the rapid disassembly between the feeding plate 40 and the push drive source 30, making it easy to replace, repair, or clean the feeding plate 40, thus improving production flexibility and equipment maintainability.

[0026] The lateral drive mechanism 20 drives the feeding plate 40 to move laterally, the push drive source 30 drives the feeding plate 40 to rise and fall, and the guide component 60 guides the feeding plate 40 during the rising and falling process to prevent the feeding plate 40 from shifting its position. The quick-release component 70 facilitates quick disassembly between the feeding plate 40 and the push drive source 30. After the connecting piece is placed in the receiving groove 41, the feeding plate 40 moves to a position below the pressure plate 50, and multiple welding positions on the connecting piece are welded through the slot 51.

[0027] The lateral and vertical movements of the feeding plate 40 are achieved by using a lateral drive mechanism 20 and a push drive source 30, satisfying the position movement requirements of the feeding plate 40. The pressure plate 50 is used to press and position the connecting pieces on the feeding plate 40, preventing the connecting pieces from shifting. The guide assembly 60 is used to guide the position of the feeding plate 40, ensuring the accuracy of the feeding plate 40 during the lifting process.

The transverse drive mechanism 20 also includes a guide rail 23 for guiding the transverse slide 22, with the transverse slide 22 slidably positioned on the guide rail 23. The four sets of guide assemblies 60 can guide the feeding plate 40 from multiple directions, providing a more stable and reliable guiding effect, making the feeding plate 40 more stable during lifting and lowering, and further improving the welding accuracy and quality. The guide rail 23 in the transverse drive mechanism 20 provides guidance for the transverse slide 22, making the transverse slide 22 more stable during movement, reducing shaking and deviation, and ensuring the accuracy and stability of the feeding plate 40 during transverse movement.

[0033] The push drive source 30 adopts a push drive cylinder. The quick-release assembly 70 includes a first connecting block 71 and a second connecting block 72.
