Description

一种独立分块吸附平台、控制电路及控制方法 技术领域
本公开属于板材吸附裁切领域，尤其涉及一种独立分块吸附平台、控制电路及控制方法。
背景技术
本部分的陈述仅仅是提供了与本公开相关的背景技术信息，不必然构成在先技术。
当前，液晶显示行业的发展促使了生产液晶显示器配件的公司的兴起。导光板和扩散板是其中最主要的生产配件，是液晶显示器的核心部件之一。导光板和扩散板在批量生产时通常使用成型机进行裁切，但在打样和小批试流时通常采用打样机进行裁切(这是因为在未量产之前设计的不确定因素，可能要进行设计变更，使用打样机更灵活，操作比成型机更简单)。导光板或者扩散板需要放置到打样机的吸附平台上进行固定，然后进行打样切割。
发明人发现，不单单是导光板与扩散板裁切行业，在诸如皮革、印刷、医疗行业所使用的吸附平台存在以下问题：
(1)现有的吸附平台通常是整个面全部吸附，当遇到板材小于吸附面时，由于板材未盖住整个吸附面而导致吸附效果大大下降，工作人员往往是拿胶带粘住板材，使其不在切割时翘起，这无疑增加了工作量和工作耗材；
(2)板材的形状也不一定都是固定的(有时候板材需要进行二次加工，形状不会是最初的正规的矩形)，传统意义上的分区吸附其实并不灵活，比如说裁切“H”形板材的时候，传统的分区并不能满足整体吸附的要求，况且分区吸附采取的分区方式往往是通过改变吸附平台下部的真空腔隔板的分布实现的，该方法密封性差且不能使吸附力均匀分布，而且真空腔过大同样会使吸附延迟，也就是当打开吸附开关后并不能瞬间吸附，而是隔一段时间才能吸附，浪费工时。
发明内容
为了解决上述问题，本公开的第一方面提供了一种独立分块吸附平台，其具有板材独立分块吸附且吸附更加牢固的效果。
本公开的第一方面的一种独立分块吸附平台的技术方案为：

密封框，所述密封框由M×N个边框构成且对应设置于吸附主板和气孔板之间；M和N均为正整数，且M和N两者中至少有一者为大于1的正整数。
进一步的，每个凹槽区域内设置有通气孔，所述通气孔通过对应弯管与通气管道相连通。
上述方案的优点在于，利用通气管道和弯管及通气孔，抽取凹槽内的真空来达到对相应凹槽区域上方板材的独立吸附的效果。
进一步的，所述通气孔设置有凹槽区域的中心点位置。
上述方案的优点在于，通气孔设置有凹槽区域的中心点位置，有利于吸附力均匀，能够稳定吸附相应板材。
需要说明的是，通气孔也可设置在凹槽区域的预设位置处。
进一步的，所述阀门设置在弯管上。
上述方案的优点在于，每个阀门与一个弯管相对应，这样能够达到独立控制吸附相应区域板材的目的。
进一步的，所述吸附主平台是一体注塑成型。
进一步的，凹槽区域为倒金字塔形。
上述方案的优点在于，一是可以方便主平台在注塑时的出模，二是可以减小真空腔体积，使得吸附迅速。
进一步的，所述阀门为手动阀门。
上述方案的优点在于，这样能够根据板材实际切割需求，手动控制相应阀门的开闭，达到板材区域独立吸附的功能。
作为可选实施例，所述阀门为电磁阀，所述电磁阀与控制器相连。
上述方案的优点在于，这样可自动控制相应阀门的开闭，能够快速准确地独立吸附板材的相应区域。
进一步的，所述通气管道包括一个主通气管和M个副通气管；每个副通气 管与对应凹槽区域相连通，每个副通气管的一端封闭，另一端均与主通气管相连通；所述主通气管的一端封闭，另一端与抽真空装置相连通。
上述方案的优点在于，当任意形状的板材放置到气孔板上，都可以根据板材的实际形状，开启不同位置的阀门，使得对应的部位产生吸附力，吸附住板材。
作为可选实施例，所述通气管道包括一个主通气管和N个副通气管；每个副通气管与对应凹槽区域相连通，每个副通气管的一端封闭，另一端均与主通气管相连通；所述主通气管的一端封闭，另一端与抽真空装置相连通。
进一步的，所述主通气管通过第一固定块固定在吸附主平台的下方。
上述方案的优点在于，利用第一固定块能够将主通气管稳定固定在吸附主平台的下方。
进一步的，每个所述副通气管通过相应的第二固定块固定在吸附主平台的下方。
上述方案的优点在于，利用第二固定块能够将副通气管稳定固定在吸附主平台的下方。
为了解决上述问题，本公开的第二方面提供了一种独立分块吸附平台的控制电路，其可以根据板材的实际形状，开启不同位置的阀门，使得对应的部位产生吸附力，吸附住板材。

进一步的，所述第一继电器与驱动电机之间还串接有第二继电器。
其中，第一继电器可为电磁继电器；
第二继电器可为热继电器。
电磁继电器是用较小的电流、较低的电压去控制较大电流、较高的电压的一种“自动开关”，在电路中起着自动调节、安全保护和转换电路的作用。
热继电器的工作原理是：电流入热元件的电流产生热量，使有不同膨胀系数的双金属片发生形变，当形变达到一定距离时，就推动连杆动作，使控制电路断开，从而使接触器失电，主电路断开，实现电动机的过载保护。热继电器作为电动机的过载保护元件，其具有体积小，结构简单和成本低的优点。
为了解决上述问题，本公开的第三方面提供了一种独立分块吸附平台的控制电路的控制方法，其可以根据板材的实际形状，开启不同位置的阀门，使得对应的部位产生吸附力，吸附住板材。
本公开的第三方面的一种独立分块吸附平台的控制电路的控制方法的技术方案为：
本公开的一种独立分块吸附平台的控制电路的控制方法，包括：
根据板材形状确定板材的吸附范围；
闭合相应串联支路中的开关，同时打开相应开关对应的阀门；
第一继电器的线圈部分通电，吸引第一继电器的开关部分闭合，驱动电机开始启动，吸附开始；
当加工完成后，关闭已打开的开关，控制电路断电，第一继电器的线圈断电，从而使第一继电器的开关部分断开，驱动电机停止工作。
本公开的有益效果是：
(1)本公开的独立分块吸附平台制造简单，使用方便：通过将吸附主平台设计成M×N个区域，每个区域下都设置有一个阀门，使每个区域都是独立的，可吸附多种形状尺寸的板材(包括形状规则和不规则的，都可吸附)，吸附灵活。
(2)本公开在吸附主板和气孔板之间设置密封框，密封框由M×N个边框构成且与吸附主板对应设置，这样使得能够密封住其他渠道，使气体只从气孔板的小孔中吸入，形成有效吸附，使得整个独立分块吸附平台密封性好，吸附迅速。
(3)本公开的独立分块吸附平台的控制电路，当开启任意一个阀门的开关时，其开关对应控制的相应区域的阀门打开，同时，抽真空装置开始工作，吸附住其上的板材，可以根据板材的形状，打开相应区域的电磁流量阀的开关，使吸附区域更加贴近于板材外形，使吸附更牢固，减少工人工时，节省时间。

具体实施方式
应该指出，以下详细说明都是例示性的，旨在对本公开提供进一步的说明。除非另有指明，本文使用的所有技术和科学术语具有与本公开所属技术领域的普通技术人员通常理解的相同含义。
需要注意的是，这里所使用的术语仅是为了描述具体实施方式，而非意图限制根据本公开的示例性实施方式。如在这里所使用的，除非上下文另外明确指出，否则单数形式也意图包括复数形式，此外，还应当理解的是，当在本说明书中使用术语“包含”和/或“包括”时，其指明存在特征、步骤、操作、器件、组件和/或它们的组合。
如图1所示，本实施例的一种独立分块吸附平台，包括：
吸附主平台3，所述吸附主平台被分割成M×N个凹槽区域，每个凹槽区域均通过通气管道与抽真空装置相连通，每个凹槽区域与对应通气管道连通之间串接有对应阀门9，每个阀门9均可独立工作；
气孔板1，所述气孔板上均布有气孔，所述气孔板设置于吸附主板上方；
密封框2，所述密封框由M×N个边框构成且对应设置于吸附主板和气孔板之间；M和N均为正整数，且M和N两者中至少有一者为大于1的正整数。
本实施例的独立分块吸附平台的整体正面结构如图7所示，背部结构如图8所示，结构极其简单。
在本实施例中，最核心的部件是吸附主平台3，如图4和图5所示。整个平台是一体注塑成型，上侧结构分成M×N个凹槽区域，如图4所示分成了4×4个凹槽区域。
每个凹槽区域的空间为倒金字塔形，这样做一是可以方便主平台在注塑时的出模，二是可以减小真空腔体积，使得吸附迅速。
吸附主平台3的上方是气孔板1，如图2所示。气孔板1上均布气孔。气孔板的作用，一是承载板材，二是封住吸附主平台3上的每个凹槽区域的空间，通过气孔使得吸附力变得均匀。如图9所示，气孔板上表面印有和其下吸附主平台分割的单元区域相应的方框，其内印有A1、A2、A3、A4、B1、B2、B3、B4、C1、C2、C3、C4、D1、D2、D3、D4的编号，作用是让工作人员可以对气孔板下的独立吸附模块一目了然，更精确的放置板材在合适位置。
气孔板1与主平台3之间是密封框2，如图3所示，其作用是密封住其他渠道，使气体只从气孔板1的小孔中吸入，形成有效吸附。
每个凹槽区域的空间的下面都居中设有通气孔，通气孔向下延伸，形成一个短管，短管与弯管相连通，进而在与通气管道相连，形状如图6所示。
本实施例利用通气管道和弯管及通气孔，抽取凹槽内的真空来达到对相应凹槽区域上方板材的独立吸附的效果。
而且通气孔设置有凹槽区域的中心点位置，有利于吸附力均匀，能够稳定吸附相应板材。
需要说明的是，通气孔也可设置在凹槽区域的预设位置处。
在具体实施中，如图6所示，所述阀门9设置在弯管上。
每个阀门与一个弯管相对应，这样能够达到独立控制吸附相应区域板材的目的。
在具体实施中，所述阀门为手动阀门。
这样能够根据板材实际切割需求，手动控制相应阀门的开闭，达到板材区域独立吸附的功能。
作为可选实施例，所述阀门为电磁阀，所述电磁阀与控制器相连。
这样可自动控制相应阀门的开闭，能够快速准确地独立吸附板材的相应区域。
在具体实施中，如图6所示，通气管道包括一个主通气管5和M(例如：M为4)个副通气管7；每个副通气管7与对应凹槽区域相连通，每个副通气管7的一端封闭，另一端均与主通气管5相连通；所述主通气管5的一端封闭，另一端与抽真空装置相连通。
这样当任意形状的板材放置到气孔板上，都可以根据板材的实际形状，开启不同位置的阀门，使得对应的部位产生吸附力，吸附住板材。
作为可选实施例，所述通气管道包括一个主通气管和N(例如：N为4)个副通气管；每个副通气管与对应凹槽区域相连通，每个副通气管的一端封闭，另一端均与主通气管相连通；所述主通气管的一端封闭，另一端与抽真空装置相连通。
具体地，所述主通气管5通过第一固定块4固定在吸附主平台3的下方。
每个所述副通气管7通过相应的第二固定块6固定在吸附主平台3的下方。
这样利用第一固定块能够将主通气管稳定固定在吸附主平台的下方。
利用第二固定块能够将副通气管稳定固定在吸附主平台的下方。
本实施例的独立分块吸附平台制造简单，使用方便：通过将吸附主平台设计成M×N个区域，每个区域下都设置有一个阀门，使每个区域都是独立的，可吸附多种形状尺寸的板材(包括形状规则和不规则的，都可吸附)，吸附灵活。
本实施例在吸附主板和气孔板之间设置密封框，密封框由M×N个边框构成且与吸附主板对应设置，这样使得能够密封住其他渠道，使气体只从气孔板的小孔中吸入，形成有效吸附，使得整个独立分块吸附平台密封性好，吸附迅速。
如图10所示，本实施例的一种独立分块吸附平台的控制电路，所述抽真空装置包括驱动电机和真空泵，驱动电机用于驱动真空泵启停；真空泵与通气管道相连通；所述控制电路，包括：
串联支路，所述串联支路的数量与阀门数量相同；每个串联支路由开关和阀门串接而成；
所有串联支路并联连接形成并联电路，所述并联电路通过第一继电器与驱动电机连接。
具体地，所述第一继电器与驱动电机之间还串接有第二继电器。
其中，第一继电器可为电磁继电器；
第二继电器可为热继电器。
具体地，在图10中的“M”代表真空机的电机，QF表示空气开关，作用是当电路中电流过大时自动断开保护电机。FR(图中有两个FR，这是按电气电路图标准绘制的，不存在重复标注的问题)是热继电器，作用是当电路里的电流增大时,切断控制回路的电源，防止器件烧坏。YV表示阀门。
电磁继电器是用较小的电流、较低的电压去控制较大电流、较高的电压的一种“自动开关”，在电路中起着自动调节、安全保护和转换电路的作用。
热继电器的工作原理是：电流入热元件的电流产生热量，使有不同膨胀系数的双金属片发生形变，当形变达到一定距离时，就推动连杆动作，使控制电路断开，从而使接触器失电，主电路断开，实现电动机的过载保护。热继电器作为电动机的过载保护元件，其具有体积小，结构简单和成本低的优点。
本实施例的一种独立分块吸附平台的控制电路的控制方法，包括：
根据板材形状确定板材的吸附范围；
闭合相应串联支路中的开关，同时打开相应开关对应的阀门；
第一继电器的线圈部分通电，吸引第一继电器的开关部分闭合，驱动电机开始启动，吸附开始；
当加工完成后，关闭已打开的开关，控制电路断电，第一继电器的线圈断电，从而使第一继电器的开关部分断开，驱动电机停止工作。
具体地，当阀门为电磁阀，且第一继电器为电磁继电器时，本实施例的一种独立分块吸附平台的控制电路的控制方法为：
首先，工作电路(即左侧主电路)的接通，除了靠一个总闸(即空气开关QF)控制外，最主要的控制还在于工作电路中的电磁继电器KM(开关部分)。当工作人员根据板材形状，确定板材的吸附范围后，闭合控制电路中的相应开关，同时打开相应开关对应的电磁阀，紧接着，电磁继电器KM的线圈部分通电，吸引电磁继电器KM的开关部分闭合，驱动电机开始启动，吸附开始，当加工 完成后，关闭已打开的开关，控制电路断电，电磁继电器KM的线圈断电，从而使主电路的电磁继电器KM的开关部分断开，驱动电机停止工作。
本实施例的独立分块吸附平台的控制电路，当开启任意一个阀门的开关时，其开关对应控制的相应区域的阀门打开，同时，抽真空装置开始工作，吸附住其上的板材，可以根据板材的形状，打开相应区域的电磁流量阀的开关，使吸附区域更加贴近于板材外形，使吸附更牢固，减少工人工时，节省时间。
上述虽然结合附图对本公开的具体实施方式进行了描述，但并非对本公开保护范围的限制，所属领域技术人员应该明白，在本公开的技术方案的基础上，本领域技术人员不需要付出创造性劳动即可做出的各种修改或变形仍在本公开的保护范围以内。
