Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a detonator laser coding line. Background technique [0002] From 2002 to 2005, the laser coding of industrial detonators adopts the coding mode of Shenzhen Han’s Laser Company, that is, the mold equipped with detonators is sent to the laser coding area with a long magnetic cylinder (1200mm), and then hooked to the laser coding by a magnetic cylinder (500mm) On the stage, after the two ends of the laser table are closed, the laser starts to code the detonator. After coding, the original route returns to the belt transportation line, and the next model of detonator can enter the code on the coding table. Die coding requires nine actions and many control actions. The spring hook on the mold hook cylinder is easily damaged and needs to be replaced every two days, and the mold often does not hook properly, which seriously affects the coding quality and coding efficiency of the det...

Problems solved by technology

[0002] From 2002 to 2005, the laser coding of industrial detonators adopted the coding mode of Shenzhen Han’s Laser Company, that is, a long magnetic cylinder (1200mm) was used to send the mold with the detonator to the laser coding area, and then the magnetic cylinder (500mm) hooked it to the laser coding table. After the two ends of the laser table were closed, the laser began to code the detonators. Nine actions, many control actions, the spring hook on the hook mold cylinder is easy to break, and needs to be replaced every two days, and the mold is often not hooked in place, which seriously affects the coding quality and coding efficiency of the detonator

And during laser coding, use the cylinder to directly push or hook the mold with 50 rounds of detonators. The inertia is large. The collision of the mold will make the detonators in the mold jump out of the mold. It is easy to be detonated by the laser, causing the detonator of the mold to explode. If the explosion cannot be vented, it will cause the detonator on the belt line to explode and cause devastating damage to the laser marking head. Every time the laser coding explosion occurs, the laser head is almost blown up, and the loss is about 30,000 yuan

In short, the past detonator coding method resulted in low coding efficiency, and the shift output was only 40,000 rounds; the coding quality was poor, the coding handwriting was blurred, the depth of the notch was not up to standard, and the safety hazard was great.
