[0001] This utility model relates to an automatic loading and pressing system for electric detonators, and more particularly to a continuous assembly system for electric detonators with leads. Background Technology

[0002] Currently, the production of electric detonators in special pyrotechnics assembly workshops relies on a manual, assembly-line loading and pressing process. Highly dangerous steps such as weighing, loading, pressing, and mold removal require six people.

However, this loading method is a fixed-volume loading method, with relatively uncontrollable accuracy and is affected by factors such as the sensitivity of the explosive, and is currently only applied to explosives. The current pressing method involves manually placing the mold into a servo press for automatic pressing. All these operations are performed behind a safety shield, posing a significant threat to personnel safety. Summary of the Invention

The barcode scanner 17 scans the jig, the lifting cylinder 18 lifts and fixes it, the clamping sleeve 2 is assembled, the clamping cover block 1 is assembled, and it waits for the back-end plate. The process jig continues in a cycle. The jig is sent to the filling station through the mold conveying mechanism; after the jig flows in, the reciprocating motion of each axis repeats the actions of the mold installation station. The lifting cylinder lifts and fixes it, the barcode scanner scans the jig, and after the jig is fixed, the filling begins. The clamping cylinder 25 clamps the medicine disc, and then the mechanism performs the filling action. After the filling is completed, the clamping cylinder 25 clamps the medicine disc back onto the jig tray. After the filling is completed, it flows into the pressing station. In the pressing station, the servo motor 26 in the servo press structure moves downward to press the medicine. After the punch contacts the workpiece 29, the force sensor feeds back the pressure data to the control system in real time. It has an online pressing management function, which can distinguish between good and bad products online, and also has an online data recording function. After the drug is pressed, the punch and the drug sleeve are cleaned. After the jig flows in, it is fixed. The punch body 30 grips the punch 5 with the gripping robot. The shaft moves and transports the punch 5 to the cleaning device 32 for rotation cleaning. The lint-free cloth roll 33 gently wipes the punch 5. At the same time, the take-up roll 36 rolls in the used lint-free cloth roll 33 and keeps the cloth surface taut by adjusting the spring tension.
