Abstract

The utility model relates to a full automatic IC strip laser marking machine, comprising a body; wherein, a PC device and an electric control system are arranged in the body; a loading-unloading outlet device, a strip conveying device, a laser marking device, a detection system and a removing device which are controlled by the PC device are arranged on the body; the loading outlet device and the unloading outlet device are arranged on both sides of the body, and the strip conveying device is arranged between the two devices. Besides, a direction detection device, a batch number detection device, a pre-marking removing device, a laser marking device, a post-marking quality detection device and a post-marking removing device are arranged on two conveying lines of the both sides of the strip conveying device in sequence, and a marking position detection device is arranged under the laser marking device. Because the loading, conveying, detecting, removing and marking devices which are controlled by the PC device are arranged on the marking machine, the whole marking process is accurate and reasonable; meanwhile, the labor intensity can be reduced.

Description

technical field [0001] The present invention relates to a new equipment for marking IC strips. More precisely, it involves loading, testing, marking, and re-testing one by one with multi-standard strip chips, and the different detected each time. The qualified strips are immediately removed by the rejecting device there, and the marked strips are pushed into the unloading box, which is a fully automatic IC strip laser marking machine. Background technique [0002] Marking machines are widely used in the surface marking of integrated circuits in the IC industry. According to the different requirements of use, the integrated circuit boards used in the IC industry have three forms: strips (combined chips) or chips (block granular chips) and wafers. The material bar is a sheet material composed of several chips. When marking each chip on the material bar, the automatic marking is realized directly by conveying the material bar. The chip is a small piece of granular material, w...
