本申请人采用一种显示面板周转或出货方式。采用珍珠棉垫片和聚丙烯垫片两种缓冲泡棉作为周转或是出货显示面板22的包材。周转或是包装出货时，采用机台自动吸附垫片10、显示面板22，间隔放在泡沫盒内，如图1所示。
在机台运行过程中，吸附显示面板22的成功率为100％，而吸附垫片10存在机率性失败。不能成功吸附珍珠棉垫片的原因有两个：
1、珍珠棉垫片的制造工艺是采用上层膜15、下层膜16和中间层17热压贴合。贴合过程不可避免的造成波浪起伏和局部翘曲，起伏严重时会导致机台真空吸附失败，如图2和图3所示。
2、珍珠棉垫片材质柔软，在原料厂包装、运输出货给面板厂或是面板厂厂内周转使用过程，受外力而变形、褶皱、破损等等，均会导致机台真空吸附失败。
不能成功吸附的原因是聚丙烯垫片的原因是：
聚丙烯垫片材质硬，为了获得缓冲性能且避免与显示面板粘连，聚丙烯垫片表面需丝印纹路，而这种纹理会导致机台真空吸附时，机率性失败。
下面结合附图和较佳的实施例对本申请作进一步说明。
如图1至图7所示，本申请实施例公布了一种缓冲衬垫10，包括：主体14，设置为隔开显示面板22；定位吸附结构11，设置在主体14的表面上，供机台20的吸嘴21吸附；定位吸附结构11对应吸嘴21的上表面为光滑平面。
具体的，主体包括上膜层15、下膜层16和中间层17，中间层17设置在上层膜15和下层膜16的中间，中间层17的材质为泡棉，中间层17包括多个圆孔18，上层膜15和下层膜16的外表面不平坦。
本方案中，一般的缓冲衬垫10表面都为不平整不光滑的表面，在吸附过程中就有可能导致吸附失败，现在在缓冲衬垫10表面设置定位吸附结构11，吸嘴21吸附在定位吸附结构11的光滑平面上，使得吸附更加稳定。
在一个实施例中，定位吸附结构11的上表面面积大于吸嘴21的真空吸附面积。
本方案中，定位吸附结构11上表面的面积大于吸嘴21的真空吸附面积，使吸嘴21全部吸附在定位吸附结构11上表面上，使吸嘴21稳定吸附。
在一个实施例中，定位吸附结构11至少有两个。
本方案中，设置至少两个定位吸附结构11，对应的增加了吸附面积，使的吸附得更稳。
在一个实施例中，定位吸附结构11呈对称分布。
本方案中，定位吸附结构11呈对称分布，吸嘴21分别吸附在各个定位吸附结构11的上表面上，使得吸嘴21对缓冲衬垫10的吸附力分布均匀，吸附更加稳定。
在一个实施例中，主体14包括第一凹槽12，设置定位吸附结构11。
本方案中，在生产的过程中，如果直接在表面上设置定位吸附结构11的话，会造成设置的位置不准确，挖个凹槽设置定位吸附结构11，在生产时起到一个对位效果，节省对位时间。
在一个实施例中，定位吸附结构11的厚度小于第一凹槽12的深度。
本方案中，缓冲衬垫10在工作过程中会有一些压缩形变来起到缓冲作用，定位吸附结构11的厚度小于第一凹槽12的深度，提供一个形变的空间，不影响缓冲衬垫10的缓冲作用。
在一个实施例中，主体14包括第二凹槽13，第二凹槽13为通槽，将主体14打穿。
本方案中，在取出显示面板22的时候，显示面板22和缓冲衬垫10会粘连在一起，在缓冲衬垫10上设置通槽，排出空气，防止显示面板22和缓冲衬垫10粘连在一起。
在一个实施例中，第二凹槽13对称分布。具体的，第二凹槽13为矩形分布，第二凹槽13分别位于矩形的四个角处。
本方案中，第二凹槽13对称分布，防止透气不均匀造成缓冲衬垫10变形从而导致机台20吸附失败。
在一个实施例中，缓冲衬垫10包括第一凹槽12和第二凹槽13，第一凹槽12与第二凹槽13的形状不相同，第一凹槽12与第二凹槽13间隔分布。
