The first pressing assembly 491 and the second pressing assembly 492 have the same structure and both comprise a pressing cylinder 4911 and a pressing block 4912 driven by the pressing cylinder 4911 to press the bus bar on the bus bar positioning platform, and the pressing block 4912 is aligned with the side edge of the bus bar positioning platform. The bending assembly 493 comprises a bending cylinder 4931, a mounting block 4932 driven by the bending cylinder 4931 to move up and down, and a first roller 4933 and a second roller 4934 respectively mounted on both ends of the mounting block 4932.The second bus bar is cut off and positioned on the second bus bar positioning platform 46, and then the first bus bar is cut off and positioned on the first bus bar positioning platform 45. The first bus bar and the second bus bar are opposite to each other. In the initial state, the head of the first bus bar extends out of the first bus bar positioning platform 45, and the tail of the second bus bar extends out of the second bus bar positioning platform 46. The first roller 4933 is located directly below the head of the first bus bar, and the second roller 4934 is located directly below the tail of the second bus bar. When the straight-line driving module 47 drives the first bus bar positioning platform 45 and the second bus bar positioning platform 46 to move away to a position, the first pressing assembly 491 acts to press the position close to the head of the first bus bar on the first bus bar positioning platform 45, and the second pressing assembly 492 acts to press the position close to the tail of the second bus bar on the second bus bar positioning platform 46. The bending cylinder 4931 drives the mounting block 4932 to drive the first roller 4933 and the second roller 4934 to rise. The first roller 4933 pushes the head of the first bus bar upward. Since the pressing block 4912 is aligned with the side edge of the first bus bar positioning platform 45, the head of the first bus bar changes from a horizontal state to a vertical state. At the same time, the second roller 4934 pushes the tail of the second bus bar upward. Since the pressing block 4912 is aligned with the side edge of the second bus bar positioning platform 46, the tail of the second bus bar changes from a horizontal state to a vertical state. Thus, the bending action of the bus bar is completed. The bending action of the butt joint of two bus bars can be completed at the same time. The bending action is simple and has high bending efficiency. After the bending is completed, when the straight-line driving module 47 drives the first bus bar positioning platform 45 and the second bus bar positioning platform 46 to move close to a position, the first material taking and pasting mechanism 61 takes away the bus bar 300.
