Description

一种真空玻璃产品 技术领域
本发明涉及真空玻璃技术领域，尤其是一种真空玻璃产品。
背景技术
真空玻璃是一种新兴的玻璃品类，一般由两片玻璃构成，在两片玻璃之间是真空层，由于此真空层的存在使得真空玻璃在隔音、隔热、防结露方面具有良好的性能表现，也更加符合国家对节能、环保的发展要求。
真空玻璃的封接质量直接影响到真空玻璃的性能，目前真空玻璃的封接主要采用两种方法：一种是采用低玻粉进行封接，一种是采用金属进行封接。当采用金属进行封接时，需先在两块玻璃基板相对面的边缘部位制备金属层，然后再采用钎焊工艺使得金属层与焊料之间牢固连接，从而实现两块玻璃基板的气密封接。
在封接过程中，可以采用高频感应加热的方式对钎焊料进行加热，高频感应焊接头由高频感应线圈盘绕而成。在焊接过程中，高频感应焊接头的中心线对准焊带中线，高频感应焊接头沿着焊带中线匀速前行，从而实现真空玻璃周边的气密焊接。
由于焊料和金属层共同存在于封接区域，在高频感应焊接头工作时，除了对焊料进行加热外，还对封接区域内的金属层进行加热。参考图1，在实际生产过程中发现，玻璃基板在其拐角区域5经常出现金属层3过烧现象，使得金属层3与玻璃基板的结合强度大幅度降低。例如：当金属层为烧结在玻璃基板上的银膜层时，在玻璃基板拐角区域银膜中的银随着过度加热会熔入钎焊料中，从而使生产的真空玻璃在拐角部位焊接强度大幅下降，影响真空玻璃焊接的可靠性和使用寿命。
发明内容
针对现有技术中存在的感应加热焊接会使真空玻璃拐角处焊接强度降低的问题，发明人研究发现：高频感应焊接头在拐角区域处必然存在减速-变向-加速的过程，因此，真空玻璃拐角区域的内角部位的感应加热时间过长，同时加热过程中金属层的边部加热速度明显大于金属层中心的加热速度，这是是导致拐角区域的金属层过烧的主要原因，拐角区域的内角部位过烧尤为严重。
发明人研究发现：改变高频感应焊接头中心的运行轨迹与金属层宽度方向中线的相对位置，使高频感应焊接头中心的运行轨迹与金属层宽度方向中线相偏离，从而降低拐角区域内金属层的感应功率，从而避免拐角区域的金属层出现过烧现象。
一种改变高频感应焊接头中心的运行轨迹与金属层宽度方向中线的相对位置的方式为：改变金属层的形状，使金属层在拐角区域的内缘和外缘均为弧形。此时高频感应焊接头在拐角区域运行时便走在了金属层宽度方向中线，避免了拐角区域金属层过烧的问题。基于上述的封接方法可以得到一种真空玻璃产品。该真空玻璃产品的结构如下：
