The AI positioning system is used to identify the position of the drug case and drug-type cover, and guide the robot to accurately locate and place the drug case and drug-type cover. Composed of lifting mechanism and composite secondary positioning mechanism, the multi-station pressing platform is installed on the side of the workbench of the special hydraulic press for perforating charges, and the position conversion of various assembly processes before the pressing process is completed through platform lifting and rotating stations. The multi-station pressing platform is equipped with stations such as upper casing, setting of the centralizing sleeve, placing of the cover, pressing, removing bombs and cleaning. Each station is equipped with a mold, a die, and a middle mold to realize automatic and assembly line continuous pressing production. The picking and placing mechanism of the centralizing sleeve and the drug-type cover is composed of an explosion-proof servo module, an explosion-proof servo motor, a driver, a guiding and positioning device, and a clamping mechanism. The bullet-taking station grabs the centralizing sleeve and places it in the position of the cleaning mechanism. After the cleaning is completed, the centralizing sleeve is moved to the multi-station pressing platform to put the centralizing sleeve station, after waiting for the centering sleeve to be in place, place the liner cover in the shell, and set multiple stations on the circular synchronous conveyor belt to complete cleaning, cleaning, body appearance inspection, and glue coating of various perforating bullets and other processes;
• The tool press fire prevention and alarm unit (4) is composed of an isolation device, a fire extinguishing material and an alarm device. The isolation device and the fire extinguishing material are arranged around the pressing tool mold to realize closure, blocking, isolation, flame retardancy, energy absorption, Covering and other fire prevention actions form passive fire protection and trigger alarm information in time;
• The explosion-proof armor unit (5) is composed of high-strength protective armor and a buffer armor device, and is arranged at the pressing station. When an explosion occurs during the pressing process, it can effectively prevent explosion and relieve pressure, block the explosion energy transmission, and isolate other stations, to protect the safety of other workstation equipment;
• The cleaning unit (6) is composed of a tooling mold cleaning device and a perforating charge cleaning device, and the tooling mold cleaning device is composed of a convex mold cleaning device, a concave mold cleaning device, a centralizing sleeve cleaning device, a middle mold cleaning device, and a platform cleaning device Composed of an explosion-proof particle collection device, etc., the tooling mold cleaning device can effectively remove the floating charge at the tooling mold and the tooling platform, and the perforating charge cleaning device uses an anti-static copper sheet to rotate and scrape off the residue at the mouth of the perforating charge Scrub the projectile body with explosives and anti-static brushes, clamp and rotate the perforating bullets for precise positioning, position the self-adaptive scraper at the edge of the mouth, and rotate the perforating bullets to scrape off the residual explosives at the edge of the mouth, and then use the explosion-proof dust suction method, collecting the scraped floating powder to realize the cleaning of the edge of the large drug and the cleaning of the surface of the projectile;
• The glue coating unit (7) at the mouth of the perforating charge is composed of a glue supply system, a needle rotation mechanism, an electrical control system, a pneumatic system, the equipment body, equipment accessories, and an anti-curing mechanism. After the mouth of the perforating bullet is cleaned, the glue coating unit (7) applies glue to the mouth of the perforating bullet. The process standard meets the temperature resistance requirements of the perforating bullet sealing glue, and the glue application efficiency meets the production capacity requirements of the entire line. The anti-curing mechanism solves the problem of the production line, the glue curing problem at the glue application port during the intermission to achieve continuous automatic glue application;
• The product QC intelligent IA inspection unit (8) utilizes machine vision detection technology to develop an online non-destructive testing device based on image information and optical principles for the surface quality and shape accuracy of perforating bullet materials and finished products. The product QC intelligent IA inspection unit (8) is composed of the inner wall detection mechanism of the liner and the mouth edge detection mechanism. The QC intelligent IA inspection unit (8) of the product uses a smart camera to take pictures of the mouth edge of the perforating charge and the liner on the inner wall.
