Description

[0002] A flexible panel is a display panel that is flexible and bendable. The technical principle of the flexible panel mainly depends on the selection and manufacturing process of the flexible substrate material. The flexible substrate is usually made of flexible plastic or organic materials. These materials have good mechanical flexibility and electrical properties. In the manufacturing process of flexible panels, laser etching technology is widely used in cutting and processing. Laser etching has the advantages of high precision, high efficiency, and non-contact, which can meet the requirements of precision and efficiency in flexible panel manufacturing. With the continuous development of flexible display technology, high-precision laser etching equipment will be used more and more widely in flexible panel manufacturing.

[0021] Figure 6 This is a front view of the laser structure of a high-precision laser etching device for manufacturing a flexible panel provided by an embodiment of the present invention; Figure 7 is a side view of the laser structure of a high-precision laser etching device for manufacturing a flexible panel provided by an embodiment of the present invention; like Figure 2 and Figure 7 As shown, two groups of symmetrically distributed electric suction cups 111 are slidingly provided at the upper end of the panel positioning component 11, the top of the cooling box 12 is slightly higher than the height of the top of the electric suction cup 111, and the cooling box 12 does not contact the electric suction cups 111 on both sides during the sliding process.

[0022] In order to solve the problem of the temperature rise on the upper surface of the cooling box 12 like Figure 5 and Figure 7 As shown, a submersible pump 22 is fixedly installed on the inner bottom side of the cooling liquid pool 10, a water pipe 23 is fixedly installed on the output end of the submersible pump 22, a water flow groove 24 is opened inside the cooling box 12, the submersible pump 22 extends into the inside of the water flow groove 24, a water outlet 25 is opened at one end of the cooling box 12 away from the submersible pump 22, and the water cooling mechanism 13 includes a heat conducting sheet 26, and a plurality of evenly distributed fins 27 are fixedly installed on the bottom side of the heat conducting sheet 26, and the coolant contacts the fins 27 when passing through the water flow groove 24; Among them, the submersible pump 22 draws out the coolant in the coolant pool 10 and transports it to the water flow groove 24 inside the cooling box 12 through the water pipe 23. When the coolant flows in the water flow groove 24, it will contact the fins 27 at the bottom of the heat conductive sheet 26. The fins 27 can increase the heat dissipation area of ​​the heat conductive sheet 26. Since the heat conductive sheet 26 is connected to the upper side of the cooling box 12, the heat generated by the laser 9 will be conducted to the heat conductive sheet 26 and the fins 27. The coolant absorbs the heat on the fins 27 during the flow process, thereby reducing the temperature of the fins 27 and the heat conductive sheet 26, and then realizes the cooling effect on the connected equipment. The upper surface of the cooling box 12 can always be maintained at a suitable temperature by means of heat convection and heat conduction. The water inside the coolant pool 10 can also cool the device body 1, which is beneficial to prolonging the service life of the laser etching equipment.
