本申请提出了一种背板100加工方法。可以理解的是，在本申请实施例中，该背板100可以应用于显示模组，例如液晶电视等。
请结合图1至图6所示，本申请实施例中，一种背板100加工方法，包括以下步骤：
提供一板材，所述板材包括第一板10、第二板60及连接第一板10和第二板60的连接板70，所述第一板10的一面形成至少一压槽；
对所述第一板10进行若干次弯折处理，其中，若干次所述弯折处理至少包括基于所述压槽对所述第一板10进行的弯折处理，所述弯折处理的弯折方向与所述压槽的开口方向位于所述第一板10的同侧。
可以理解的，可在模具上放置用于加工背板100的板材，板材的材质为金属材质，例如钢、铁、合金、钣金或预涂板等，具体根据实际应用环境选择，在此不做限制。可选地，板材呈长方形。
本实施例中，板材通过设置于模具上，并对板材进行拉伸（如凸包、后壳、加强筋等），板材在加工过程中均是通过模具对板材实现加工成型为背板100，因此，如图1所示，本发明的背板100主要包括第一板10、第二板60及连接第一板10和第二板60的连接板70，其中，第一板10用于冲压形成中框结构，为了减少弯折板材形成的尺寸误差，在冲压板材的过程中，每冲压一次，则会产生一次生产误差，随着冲压次数的增加，误差也会进行累加，如图2至图3所示，可在第一板10上设置至少一个压槽，在对第一板10进行多次弯折的处理时，可基于压槽对第一板10进行弯折，提高弯折的精确度，且弯折的方向与压槽的开口方向位于第一板10的同侧，以防止压槽的槽口产生运动干涉。本发明所述的弯折处理，可以是利用冲压工艺进行弯折处理，也可以是利用其他可实现弯折的工艺进行弯折处理。采用压槽处理同时大幅减少折弯变形抗力，降低冲头的损耗，折弯工艺的特性折弯中，上压冲头30受力形式是向上的，可以有效承受下压冲头50向上的力，可提升冲头的使用寿命。
可以理解的是，可根据第一板10所需要弯折的次数，可在每个需要弯折的位置设置压槽，以降低单个弯折步骤所产生的误差。
以理解的是，板材可以是在一个模具上完成全部加工步骤，也可以是在不同模具上完成不同的加工步骤。
如图4所示，在上一实施例的基础上，所述对所述第一板10进行若干次弯折处理的步骤包括：
对所述第一板10进行第一次弯折，以形成与所述第一板10成角度设置的折墙11，至少一所述压槽位于所述折墙11上。
本实施例中，为了便于形成背板100的中框结构，需要对第一板10进行一次冲压，以形成折墙11，折墙11上设置有至少一个压槽，具体的，在对第一板10进行一次冲压之前，可在第一板10上进行压槽减薄处理，其中，可在第一板10的上表面进行减薄处理，以形成第一压槽A，第一压槽A的长度方向与第一板10的长度方向相同，利用第一压槽A形成上预折弯线，以便于后续的折弯操作中，可以沿着第一压槽A进行精准弯折，降低误差，对于第一压槽A的深度和槽口大小，可以依据具体的板材厚度，冲压工艺参数等进行设置。其中，形成的折墙11与第一板10成直角，也可以根据需求设设置成其他角度。
在上一实施例的基础上，如图5所示，所述压槽包括第一压槽A，所述对所述第一板10进行第一次弯折，以形成与所述第一板10成角度设置的折墙11的步骤之后还包括：
对所述折墙11进行第二次弯折，所述折墙11基于所述第一压槽A弯折形成与所述第一板10平行设置的第一折边12，其中，所述第二次弯折的弯折方向与所述第一压槽A的开口方向一致。
本实施例中，第一板10经过第一次冲压形成折墙11后，后续的冲压步骤将形成支撑显示屏的结构，因此，为了提高冲压精度，在对折墙11进行二次弯折时，需要基于第一压槽A弯折形成第一折边12，且第二次弯折的弯折方向与第一压槽A的开口方向一致，可选的第一折边12与第一板10平行设置。具体地，第二次弯折处理的位置为第一压槽A的位置，以提高弯折的精度。
在上一实施例的基础上，如图6所示，所述对所述折墙11进行第二次弯折的步骤之后还包括：
对所述第一折边12进行第三次弯折，所述第一折边12基于所述第一压槽A弯折形成与所述折墙11抵接的第二折边13，所述第二压槽B位于所述第二折边13上，其中，所述第三次弯折的弯折方向与所述第二次弯折的弯折方向相同。具体地，第三次弯折处理的位置为第二压槽B的位置，以提高弯折的精度。
本实施例中，为了提高第一板10形成中框结构的稳定性，需要对第一折边12进行第三次弯折，第三次弯折基于第二压槽B进行，且第三次弯折的弯折方向与第二次弯折的弯折方向相同，以使第二折边13紧压于第一折边12上，提高折墙11后续支撑显示屏的强度。
在上一实施例的基础上，如图6所示，所述压槽还包括第二压槽B，所述第一压槽A和所述第二压槽B位于所述折墙11的两侧，并错位设置，所述对所述第一折边12进行第三次弯折的步骤之后还包括：
对所述第二折边13进行第四次弯折，所述第二折边13基于所述第二压槽B弯折形成第三折边14，可选地，所述第三折边14与所述第一板10平行设置，其中，所述第四次弯折的弯折方向与所述第三次弯折的弯折方向相反，且所述第四次弯折的弯折方向与所述第二压槽B的开口方向一致。
本实施例中，为了形成可以容纳显示屏的中框结构，防止显示屏安装于第一折边12上后，不会凸出至折墙11的外部，需对第二折边13进行第四次弯折，其中，第二折边13基于第二压槽B弯折形成第三折边14，且第四次弯折的弯折方向与第三次弯折的弯折方向相反，第四次弯折的弯折方向与第二压槽B的开口方向一致，以保证第三折边14弯折后与第一板10平行设置，第三折边14朝向第一板10的方向内陷形成足够容纳显示屏的空间。
上述弯折步骤中，为了提高弯折后的尺寸精度，可在第一板10的下表面进行减薄处理，形成第二压槽B，利用第二压槽B形成下预折弯线，以便于后续的折弯操作中，可以沿着第二压槽B进行精准弯折，降低误差。
可以理解的是，第二压槽B与第一压槽A间隔设置，且两者均位于折墙11上。
上述通过在第一板10的上下表面设置第一压槽A和第二压槽B，采用压槽处理可大幅减少折弯变形抗力，降低冲头的损耗，有效降低每次冲压带来的误差，提高产品的合格率，同时也便于一次冲压形成第二折边13和第三折边14。
经过上述压槽处理的步骤后，第一板10的边缘会产生飞边毛刺，可以在上述步骤完成后，或者在每个步骤完成后，去除飞边毛刺。
在上一实施例的基础上，对所述折墙11进行第二次弯折的弯折角度为90度，对所述第二折边13进行第四次弯折的弯折角度为90度。
本实施例中，由于冲压过程需要用到入子20、冲压头等模具，因此，为了便于冲压形成所需的结构，折墙11进行第二次弯折的弯折角度为90度，对第二折边13进行第四次弯折的弯折角度为90度，以便于后续一次性冲压形成第二折边13和第三折边14。
请参照图7、图8以及图9，本申请还具备一下实施例：
以第一板10的右侧边缘进行冲压为例。将第一板10压紧于入子20和上压冲头30之间，防止第一板10发生位置偏移，同时，利用右冲压头40冲压折墙11，使得位于入子20外部的折墙11边缘受力向第一方向（此处为顺时针方向）弯折90度。由于第一压槽A形成的上预折弯线，可以提高弯折的精度，因此，第一压槽A位于入子20远离第一板10一侧的边缘上，以使位于入子20外部的折墙11受力沿第一压槽A弯折90度，以形成与第一板10平行的第一折边12。
可以理解的是，当第一折边12形成后，可以对转角进行修整。
下压冲头50向上对第一折边12进行冲压，使位于所述第一压槽A与所述第二压槽B之间的第一折边12在第一方向上沿所述第一压槽A弯折90度，以形成第二折边13，第二折边13与所述折墙11压紧，且剩余的所述第二折边13在第二方向上沿所述第二压槽B弯折90度，以形成与第一板10平行的第三折边14，所述第三折边14与第二折边13配合形成用于放置光学组件（例如显示屏）的安装腔C；
其中，所述第一方向与所述第二方向相反。
本申请的冲压工艺中，在入子20固定折墙11后，利用下冲压头向上对折墙11进行冲压，使位于第一压槽A与第二压槽B之间的第二折边13在第一方向上沿第一压槽A弯折90度，并与折墙11压紧，而第三折边14在第二方向上（此处为逆时针方向）沿第二压槽B弯折90度，并与第一板10平行设置，此时第三折边14由于沿着第二压槽B弯折形成，因此，一次性形成第二折边13和第三折边14的过程中，第二折边13和第三折边14的分别沿着第一压槽A和第二压槽B精准弯折，有效提高冲压的精度。
其次，若入子20是采用悬臂形式存在，在承受下冲压头向上的力时，容易因强度不足而断裂，而本申请实施例中，由于前面有压槽处理，下冲压头需要的压力较小，且由于入子20受力形式是向上的，可以有效承受下冲压头向上的力，可提升冲头和入子20的使用寿命。
可以理解的是，第三折边14和第二折边13由第一折边12冲压而成。
在上一实施例的基础上，所述第二折边13与所述第一板10之间的间距大于等于1mm。本实施例通过在折墙11上进行压槽处理，且利用由下向上的入子20固定第一板10，使得第三折边14与第一板10之间的间距便于调节，且不受折墙11高度的限制，容易实现薄型结构成型。因此，第三折边14与第一板10之间的间距最低可到1mm。
在上一实施例的基础上，所述第一压槽A、所述第二压槽B均呈V形结构；和/或，
所述第一压槽A的两个槽壁之间的角度、所述第二压槽B的两个槽壁之间的角度均大于90度。
本实施例中，为了便于折墙11和第二折边13的弯折，第一压槽A和第二压槽B可以由V形结构的冲头进行压槽减薄作业，使得第一压槽A的两个槽壁之间的角度、第二压槽B的两个槽壁之间的角度均大于90度，在过程中，避免角度过低导致弯折无法达到预设的角度。可选地，第一压槽A的两个槽壁之间的角度、第二压槽B的两个槽壁之间的角度均为110-120度。
在上一实施例的基础上，所述第一压槽A的深度、所述第二压槽B的深度均为所述第一板10厚度的1/3至1/2。
本实施例中，第一压槽A的深度、第二压槽B的深度均为第一板10厚度的1/3至1/2，可有效减少折弯变形抗力，提升折弯的进度，降低冲头的损耗。可选的，第一压槽A的深度、第二压槽B的深度均为第一板10厚度的1/2。
本申请还提出一种背板100加工方法，包括以下步骤：
