3D curved glass hot bending device with high heating efficiency

Abstract

The invention discloses a 3D curved glass hot bending device with high heating efficiency. The device comprises a case platform, a control center is fixedly installed at one end of the case platform,a hot bending forming chamber is fixedly installed in the middle of the upper surface of the case platform, a feeding mechanism fixedly installed on the case platform is arranged at one end of the hotbending forming chamber, a discharging mechanism fixedly installed on the case platform is arranged at the other end of the hot bending forming chamber, the interior of the hot bending forming chamber is divided into a heating chamber and a cooling chamber through a partition plate, a conveying belt is transversely arranged at the lower end of the interior of the hot bending forming chamber, an upper pressing plate is fixedly installed in the middle of the inner wall of the top of the heating chamber, infrared thermometers are installed on the two sides of the upper pressing plate, and an induction hollow copper pipe coil is fixedly installed under the upper pressing plate. The heating and cooling mode is simple in structure, the size of the device is greatly reduced, and the device is more beneficial to actual use in cooperation with efficient heating efficiency.

Description

technical field [0001] The invention relates to the technical field of 3D curved glass production, in particular to a 3D curved glass thermal bending device with high heating efficiency. Background technique [0002] 3D curved glass has the advantages of thinness, transparency and cleanliness, anti-fingerprint, anti-glare, hardness, milk scratch, good weather resistance, etc. 3D curved glass can make the product new and more textured, and can also increase the curved edge touch function It brings excellent touch feel, wireless charging skills, and can solve the insufficient space for antenna layout and enhance the reception function. These characteristics of 3D curved glass meet the design requirements of 3C products (such as smart phones, smart watches, tablet computers, wearable smart products, instrument panels, etc.), and are therefore more and more widely used. [0003] The hot bending process is one of the core processes in the 3D curved glass process, and it is also ...

Problems solved by technology

[0006] The object of the present invention is to provide a 3D curved glass hot bending device with high heating efficiency to solve the problem of the heating method of the existing 3D curved glass hot bending device proposed in the above-mentioned background technology: the way of heat conduction by using the heating plate to contact the graphite mold Heating, the heating speed is slow with this heat conduction method, and the graphite mold needs to be heated to the set temperature before the graphite mold is heated, which will also cause a certain waste of time; in addition, because of the existence of the preheating link, At the same time, cooling also adopts the method of heating plate contact cooling conduction, so multiple sets of heating plates will be installed, which leads to the problem that the existing 3D curved glass bending device is large in size, complex in structure, and inconvenient to use.
