Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of laser cutting, and specifically relates to an automatic paper flattening mechanism for laser cutting. Background Art
[0002] Today, with the rapid development of technology, the traditional glass cutting process is gradually being replaced by an advanced technology called "glass laser cutting machine". This equipment not only improves the cutting efficiency but also greatly enhances the cutting accuracy, making the production of glass products more convenient and precise.
[0003] Firstly, the core component of the glass laser cutting machine is the laser generator. It generates a high-energy laser beam through a special excitation source. These laser beams pass through a series of optical elements, such as lenses, mirrors, etc., and are accurately directed and focused onto the glass surface, forming a tiny light spot.
[0004] Immediately afterwards, the laser beam moves at an extremely high speed and cuts on the glass according to a preset trajectory. Due to the highly concentrated energy of the laser, it can instantly heat the glass to the boiling point, causing it to melt or vaporize, thereby achieving the purpose of cutting. Compared with traditional mechanical cutting, laser cutting does not need to contact the glass, avoiding scratches or damages caused by mechanical pressure.
[0005] In addition to the laser generator and the cutting head, the glass laser cutting machine is also equipped with a precise positioning system and a control system. The positioning system can ensure that the laser head moves precisely according to the preset trajectory, while the control system is responsible for receiving the user's instructions and adjusting parameters such as the power and frequency of the laser in real time to adapt to different thicknesses and types of glass.
[0006] Finally, because the accuracy of laser cutting is very high, up to 1μm ± 0.01, when cutting the next piece of glass, the flatness and cleanliness of the glass placement surface are required to be very high, and there should be no cutting residues with a diameter exceeding 20μm, otherwise it is easy to cause defects such as scratches and abrasions on the glass. At present, there is no very effective means in the industry to completely remove the glass residues. Therefore, manually lay a smooth piece of paper flat on the bottom plate, then firmly fix the four sides with tape to ensure flatness, and then perform the cutting operation. After completion, remove the bottom paper and stick a new layer, and so on. Such efficiency is extremely low and greatly limits the production capacity. Therefore, an automatic paper flattening mechanism for laser cutting came into being. Content of the Utility Model
