The placement mechanism 1 is used to place the terminal 3, and the blank folding mechanism 2 performs a blank folding operation on the surplus materials 32 on both sides of the terminal body 31.

[0034] As shown Figure 1-3 in the figure, the placement mechanism 1 includes a first transverse sliding rail 11, a material loading component slidably arranged on the first transverse sliding rail 11, and a first transverse driving member 12 for driving the material loading component to slide along the first transverse sliding rail 11. One end of the first transverse sliding rail 11 is the loading end, and the other end is the processing end, and its processing end correspondingly extends to the parallel side of the blank folding mechanism 2. The material loading component includes a bottom plate 131, a first rotation driving member 132 is arranged on the bottom plate 131, and the output end of the first rotation driving member 132 is connected with a material loading plate 133, and the material loading plate 133 can rotate horizontally.

[0035] As shown Figure 1-4 in the figure, the material loading plate 133 is provided with a plurality of material loading fixtures 134 for placing terminals. The material loading fixture 134 includes a fixture frame, and an installation part 1341 and processing parts 1342 correspondingly arranged on both sides of the installation part 1341 are arranged in the fixture frame. The installation part 1341 is used to support the terminal body, which is correspondingly placed in the middle of the material loading fixture 134, and has a raised positioning block thereon, and the positioning block is adapted to the terminal body to limit the position of the terminal body 31; the processing parts 1342 are correspondingly arranged on both sides of the installation part 1341, and the processing parts 1342 are arranged as a through-hole structure that penetrates up and down. When the terminal body is placed in the installation part 1341, the surplus materials 32 on both sides of the terminal body 31 are correspondingly placed in the through-hole structure. And the material loading plate 133 is synchronously arranged as a through-hole structure corresponding to the position of the processing part 1342, which is convenient for the blank folding mechanism 2 to perform a blank folding operation on the surplus material 32.

The pressure components 22 are used to press the terminal body 31 placed on the material loading fixture 134, and the blank folding components 2 then apply a force to the surplus materials 32 on both sides of the terminal body 31 to separate them from the terminal body 31. The numbers of the pressure components 22 and the blank folding components 23 both correspond to the number of the unilateral material loading fixtures 134 on the material loading plate 133 to realize synchronous processing of multiple groups of terminals and improve the processing efficiency.

[0037] As shown Figure 1-6As shown in the figure, the blank holding assembly 22 includes a bracket 221 provided at the upper end of the frame 21.
