Description

technical field [0001] 本发明涉及3D玻璃生产领域,具体涉及一种机械式补偿3D玻璃加热装置。 Background technique [0002] 柔性OLED取代LED是必然趋势,导致玻璃盖板会升级到3D。另外,4G、5G、无线充电灯等新通讯技术的发明也促进了3D玻璃在手机上的应用。这也使得相应的玻璃生产工艺也要发生变更,且其中重点工艺之一就为3D玻璃热弯成型。此种成型技术存在两个难点:温度和精度;容易造成玻璃不同部位受热不均匀,从而产生玻璃表面质量不良 [0003] 目前对于模具进行加热的加热装置中,其普遍采用上下加热板的形式进行加热,加热时,将模具放于下加热板上,上加热板向下滑动至模具表面,然后进行加热。 [0004] 现在所使用的这种加热方式的主要缺点在于:1)多套模具存在厚度误差;会造成上加热板与模具接触不良,同时产品也同样存在公差,也会影响上加热板与模具的接触;2)上下模具合模后不可能做到模具上下表面完全平行,也会造成上加热板与模具表面接触不均匀,同时机台上多套下加热板也不可能做到完全平行,且在长期高温下工作,也存在变形。 Contents of the invention [0005] 鉴于此,本发明提供了一种可以克服模具厚度误差、使得模具上下表面平行且防止玻璃压坏的机械式补偿3D玻璃加热装置。 [0006] 本发明提供了一种机械式补偿3D玻璃加热装置,其包括: [0007] 上加热部,上加热部具有上加热板,上加热板内设置有多个第一加热通腔,第一加热通腔内穿设有第一加热棒,上加热板上还连接有多个第一导柱,多个第一导柱的顶部套装有调整板,调整板上设置有复位螺杆部和螺接部,调整板上还可滑动地穿设有多个第二导柱,第二导柱的底部连接有第一驱动板,第二导柱的顶部连接升降驱动部,升降驱动部驱动驱动板升降,第一驱动板推动加热板升降; [0008] 下加热部,下加热部设置于上加热部的下方,下加热部包括下加热板,下加热板内设置有多个加热通腔,加热通腔内穿设有第二加热棒。 [0009] 进一步地,上述上加热板的上方还设置有冷却板,冷却板可滑动地套装在第一导柱上。 [0010] 进一步地,上述第二导柱的顶部安装有第二驱动板,升降驱动部的驱动轴固定连接第二驱动板。 [001...

AI Technical Summary

Problems solved by technology

[0004] The main disadvantages of the current heating method are: 1) There are thickness errors in multiple sets of molds; it will cause poor contact between the upper heating plate and the mold, and the product also has tolerances, which will also affect the contact between the upper heating plate and the mold; 2) After the upper and lower molds are closed, it is impossible to make the upper and lower surfaces of the mold completely parallel, which will also cause uneven contact between the upper heating plate and the mold surface. At the same time, it is impossible to achieve complete parallelism with multiple sets of lower heating plates on the machine. Working at high temperature, there is also deformation
