The automatic terminal cutting and packaging machine includes: a material strip conveying track 5, a first material pulling mechanism 6, a terminal cutting mechanism 7 and a material taking mechanism 8. The material strip conveying track 5 is provided with a first positioning groove 9 for positioning the bottom of the material strip 1 and a positioning step 10 for positioning the upper and lower ends of the terminal blocks 2. The three-point positioning method is adopted to realize the stable transmission of the material strip 1 and the terminal blocks 2. The end of the material strip conveying track 5 is formed by cutting to form an upper slot 11 and a lower slot 12. The first material pulling mechanism 6 is arranged on one side of the material belt conveying track 5, and the first material pulling mechanism 6 includes a first material pulling disc 13 arranged horizontally and a first motor 14 driving the first material pulling disc 13 to rotate. A group of first gear teeth 15 adapted to the material pulling hole 4 are arranged on the circumferential surface of the first material pulling disc 13. When the first material pulling disc 13 rotates, the first gear teeth 15 cooperate with the material pulling hole 4 to pull the material belt 1 and the terminal 2 forward. The terminal cutting mechanism 7 is arranged on one side of the end of the material belt conveying track 5, and the terminal cutting mechanism 7 includes an upper alloy cutting plate 16, a lower alloy cutting plate 17, a sliding seat 18, a positioning block 19, a reset spring 20 and a cutting mechanism driving device 21. The upper alloy cutting plate 16 and the lower alloy cutting plate 17 are made of a hard alloy having a hardness greater than that of the material belt 1 and the terminal 2. The upper alloy cut-off plate 16 is fixedly inserted into the upper slot 11 of the material belt conveying track 5, the sliding seat 18 can be slidably inserted into the lower slot 12 of the material belt conveying track 5, and the lower alloy cut-off plate 17 is fixed at the rear end of the sliding seat 18. The positioning block 19 is fixed at the rear end of the sliding seat 18, and the positioning block 19 is located above the lower alloy cut-off plate 17. The front end of the upper alloy cut-off plate 16 is provided with a positioning groove 22 adapted to the positioning block 19. The positioning block 19 cooperates with the positioning groove 22 to achieve accurate positioning between the upper alloy cut-off plate 16 and the lower alloy cut-off plate 17. The reset spring 20 is arranged at the front end of the sliding seat 18 for resetting the sliding seat 18.

[0032] Preferably, the material taking mechanism driving device 24 includes an X-axis linear slide 36, a Y-axis linear slide 37, an "L"-shaped curved arm 38 and a third motor 39, the pneumatic finger 23 is mounted on the Y-axis linear slide 37, the Y-axis linear slide 37 is mounted on the X-axis linear slide 36, one end of the "L"-shaped curved arm 38 is connected to the upper end of the Y-axis linear slide 37, and the other end of the "L"-shaped curved arm 38 is connected to the third motor 39. When the third motor 39 drives the "L"-shaped curved arm 38 to rotate 90°, the pneumatic finger 23 can be driven to move from one side to the other side in an arc-shaped trajectory by utilizing the left-right and up-down degrees of freedom of the X-axis linear slide 36 and the Y-axis linear slide 37, thereby realizing the extraction of the terminal block 2 from the material belt conveyor track 5 side to the packaging carrier belt conveyor track 25 side.
