Abstract

The invention discloses an automatic transferring, loading and unloading device for high-temperature molds, a high-efficiency machining system for 3D cover glass and a machining method of the system.The automatic transferring, loading and unloading device for the high-temperature molds comprises a mold conveying mechanism which is used for conveying molds at the temperature not lower than 100 DEGC to an unloading and loading position from a discharge end of machining equipment and conveying the molds to a feed end of the machining equipment from the unloading and loading position; the unloading and loading position comprises an upper mold moving device and a part taking and arranging device, the upper mold moving device is used for lifting and dropping upper molds of the molds to controlmold opening and assembling; the part taking and arranging device is used for taking molded parts out of lower molds of the molds, taking parts from a to-be-machined part storage area and placing theparts to the lower molds. According to the scheme, manual operation is not needed, the overall machining efficiency and product yield can be increased, the output molds have no temperature limit andcan be output at higher temperature, cooling time can be reduced, time consumed for preheating is reduced, and increase of overall machining rate and decrease of energy consumption are facilitated.

Description

technical field [0001] The invention relates to the field of cover glass processing, in particular to an automatic transfer and loading and unloading device for a high-temperature forming mold, a high-efficiency 3D cover glass processing system and a processing method thereof. Background technique [0002] With the advent of the 5G signal era, the shortcomings of traditional metal shell shielding signals tend to be obvious. [0003] As a mobile phone casing, glass has many advantages such as novel appearance, comfortable feel, good plasticity, etc., and gradually replaces traditional plastic casings and metal casings. [0004] One of the latest innovations is to obtain a three-dimensional structural shape by bending the edge or center of the glass, that is, by applying pressure to the periphery of the cover glass while heating, so that the existing two-dimensional flat state of the cover glass is bent into a 3-dimensional shape. [0005] The existing hot bending machine fo...

Problems solved by technology

[0008] The resistance rod heating forming process is to heat the forming mold through the resistance heating tube and indirectly heat the forming mold to soften the glass through heat conduction, but the resistance heating is slow, and the heat loss taken away by the forming mold after passing through each station takes a long time to complete. Temperature compensation, and the maximum temperature of the heating is limited

[0009] Electromagnetic induction heating uses electromagnetic induction to generate current inside the mold, and relies on eddy current energy to heat the forming mold. Its advantage is that the forming mold can reach the temperature of the glass softening point within a few seconds. The disadvantage is that due to the characteristics of electromagnetic, the forming mold is close to the coil. The side temperature is high, and the temperature far away from the coil is low, resulting in very poor thermal uniformity of the forming mold, resulting in poor thermal uniformity of the cover glass, resulting in a low yield of the final press-molded 3D cover glass
