Abstract
The invention provides an automatic forming device for a light guide plate. The automatic forming device comprises a rack, a feeding mechanism, a first deviation correcting mechanism, a screen dot forming mechanism, a second deviation correcting mechanism and a cutting mechanism, wherein the feeding mechanism is installed on the rack, and the feeding mechanism, the first deviation correcting mechanism, the screen dot forming mechanism, the second deviation correcting mechanism and the cutting mechanism are installed on the rack and arranged in sequence in the conveying direction of feeding rollers in the feeding mechanism. The invention further provides an automatic forming method for the light guide plate. With the edge of a raw material in the length direction as a reference, the position information of the reference is judged through the first deviation correcting mechanism, the position of the raw material is corrected, and then screen dot pressing is conducted; then, the position of the raw material is further corrected through the second deviation correcting mechanism; and finally, cutting is carried out to form the light guide plate. According to the automatic forming device and method for the light guide plate, the accuracy of the screen dot forming position is ensured by carrying out first-time deviation correction before screen dot forming; and the accuracy of the cutting position is ensured by carrying out second-time deviation correction before cutting forming, so that the forming quality and production efficiency of the light guide plate are improved.
Description
technical field [0001] The present application belongs to the technical field of light guide plate processing and manufacturing, and more specifically relates to an automatic light guide plate forming device and a forming method thereof. Background technique [0002] The principle of the light guide plate is to use the dots to destroy the total reflection of the LED light source light, so that the light can come out from the light guide plate, and realize the purpose of turning the LED line light source into a surface light source. [0003] With the thinning of the light guide plate used in the keyboard backlight module, the overall thickness of the light guide plate is even less than 0.2mm. Part of it is introduced into the light guide plate, resulting in a large loss of light energy, low utilization rate, and insufficient luminous brightness. In order to solve this problem, the current countermeasure is to add a wedge-shaped structure on the light-incident side of the lig...
