The welding pin knurling forming device for terminal blocks according to claim 7, characterized in that: The welding needle pushing assembly (5) is located above the linear vibration track (22) on the side of the lifting mechanism (23) for feeding. The welding needle pushing assembly (5) includes a third cylinder (51) controlled by the electronic control module (7) and a push rod (52) driven by the third cylinder (51) so as to push the welding needle after it has been lifted by the lifting mechanism (23) into the knitting pressing assembly (3) in stages.

9. A welding pin knurling forming device for terminal blocks according to claim 8, characterized in that: The welding needle limiting component (6) is located at the discharge port of the knitting pressing component (3); the welding needle limiting component (6) includes a fourth cylinder (61) controlled by an electronic control module (7) and a limiting rod (62) that is controlled to extend and retract by the fourth cylinder (61); when the limiting rod (62) extends, it is used to abut against the welding needle at the foremost end of the knitting pressing component (3), and when it retracts, it is used to push out the welding needle at the foremost end of the knitting pressing component (3).

10. A process for knurling welding pins for terminal blocks, characterized in that: The welding pin knurling forming device for terminal blocks, including any one of claims 1-9, comprises the following steps: S1: Place the un-engraved welding needle into the vibrating plate (21), and automatically convey it to the straight vibration track (22) through vibration of the vibrating plate (21); the un-engraved welding needle is automatically conveyed to the lifting mechanism (23) through the straight vibration track (22). Before lifting, the height of the lifting mechanism (23) is equal to that of the straight vibration track (22). After lifting, the height of the lifting mechanism (23) is equal to that of the feed port of the engraving pressing component (3). S2: The height of the push rod (52) is equal to the height after the lifting mechanism (23) is lifted. The push rod (52) driven by the third cylinder (51) pushes forward, pushing the un-engraved welding needle into the engraving pressing assembly (3). S3: The limit rod (62) driven by the fourth cylinder (61) extends and closes the discharge port of the embossing pressing assembly (3), so that the push rod (52) pushes into the frontmost welding pin of the embossing pressing assembly (3) to abut the limit rod (62), and the welding pins thereafter are limited to the bottom of the pressing plate (37). S4: The upper mold (32) presses down on the welding needle, and works with the lower mold (31) to press the grooves on the upper and lower sides of the welding needle. At the same time, when the first angle (3211) on both sides of the two drive plates (321) press down, the second angle (331) and the third angle (341) are squeezed to move to the left and right sides respectively, so as to drive the left mold (33) and the right mold (34) to press the welding needle, so as to press the grooves on the left and right sides of the welding needle simultaneously. S5: The limit rod (62) driven by the fourth cylinder (61) retracts, opening the discharge port of the stitching pressing assembly (3); S6: The push rod (52) driven by the third cylinder (51) repeats the steps described in S2, pushing the un-engraved welding needle into the engraving pressing assembly (3), and at the same time pushing out the welding needle with engraving at the front end out of the engraving pressing assembly (3). S7: If the operator has not operated the electronic control module (7) after the judgment of the electronic control module (7), it is judged as a good product. The second cylinder (44) drives the first guide rail (411) to connect with the discharge port of the crimping component (3), so that the crimped welding needle falls into the good product bin (42). If the operator has operated the electronic control module (7) after the judgment of the electronic control module (7), it is judged as a defective product. The second cylinder (44) drives the second guide rail (412) to connect with the discharge port of the crimping component (3), so that the crimped welding needle falls into the defective product bin (43).
