Remain coding device and UV protection film production system

Abstract

The invention relates to the technical field of UV protection film production equipment, in particular to a remain coding device and a UV protection film production system. The remain coding device comprises code spraying devices, a splitting machine, a winding shaft, a meter counter and a processor. The code spraying devices are connected with the splitting machine. The difference between the number of the code spraying devices and the number of cutters of the splitting machine is one. The winding shaft is used for winding split UV protection films. The meter counter is used for measuring thelength of the UV protection films wound on the winding shaft and connected with the processor. The processor is connected with the code spraying devices and used for controlling the code spraying devices to spray length information on the upper surfaces of the UV protection films according to set time. Through the remain coding device, the length information can be sprayed on the upper surfaces of the UV protection films according to set time, thus, users can know the UV protection film remain in the using process and select the protection films in proper lengths according to actual demands,the phenomenon that the UV protection films are inadequate is avoided, and waste is avoided.

Description

technical field [0001] The invention relates to the technical field of UV protective film production equipment, in particular to a margin coding device and a UV protective film production system. Background technique [0002] In the packaging process of semiconductor products (such as wafers, diodes, etc.), it is usually necessary to use a UV protective film. At present, UV protective films for semiconductor products are generally straight or die-cut, and the unit is generally a roll. However, during use, the user usually does not know how much of a roll of UV protective film is left. When using it next time, it is likely that the length of the remaining UV protective film is not enough, which leads to the need to tear off the UV protective film. , re-encapsulate the product, and when the UV protective film is difficult to tear off, the unencapsulated product can only be discarded, causing waste and bringing huge economic losses to the user.
