Description

模头装置、涂布设备及涂布方法 技术领域
本发明涉及涂布技术领域，具体而言，涉及一种模头装置、涂布设备及涂布方法。
背景技术
涂布，是将糊状聚合物、熔融态聚合物或聚合物熔液涂布于纸、布、塑料薄膜上制得复合材料(膜)的方法，例如在电池极片的生产工艺中，需要在集流体上涂布浆料，再送入烘箱进行烘干，最后将烘干完成的极片进行收卷，传统电极片生产用的涂布烘干装置多为单面涂布，即完成单面的涂布之后，需要进行干燥后再进行另一面的涂布，最后再进行干燥，增加了烘箱的节数，提高了成本，且降低了生产效率，为解决了上述问题，一般可以采用双层涂布设备可通过对极片两面进行涂布，将两面涂布后的极片同时进行干燥。
现有技术中，由于部分采用双层涂布设备中的其中一个模头的出料狭缝需要朝上，相较于出料狭缝朝向水平的模头，该出料狭缝朝上的模头难以实现安装维护，可表现为，出料狭缝朝向水平的模头可以设置在料带的一侧，操作空间较大，出料狭缝需要朝上的模头的上方存在有被涂覆的料带，部分操作空间被料带占用，导致工作人员部分活动受限，或者，且在模头的出料狭缝朝向水平的情况下，模头的盖板部分沿狭缝为开口翻开后，模头的料腔开口朝上，模头料腔内的残余浆料不易滴落，易于清理，而出料狭缝朝上的模头在盖板部分翻开后，模头的料腔开口朝向侧方，模头料腔内的残余浆料会从料腔开口流落，又或者，在模头的出料狭缝朝向水平的情况下，模头上方的盖板上表面会安装有较多的零部件，这些零部件以自上而下的方式安装于模头即可，而在模头的出料狭缝朝上的情况下，这些零部件则是从侧方沿水平方向安装于模头盖板，在安装过程中需持续对零部件进行托举，不易安装。

涂布，是将糊状聚合物、熔融态聚合物或聚合物熔液涂布于纸、布、塑料薄膜上制得复合材料(膜)的方法，例如在电池极片的生产工艺中，需要在集流体上涂布浆料，再送入烘箱进行烘干，最后将烘干完成的极片进行收卷。
传统电极片生产用的涂布烘干装置多为单面涂布，即完成单面的涂布之后，需要进行干燥后再进行另一面的涂布，最后再进行干燥，增加了烘箱的节数，提高了成本，且降低了生产效率。
为解决了上述问题，一般可以采用双层涂布设备可通过对极片两面进行涂布，将两面涂布后的极片同时进行干燥。
但由于部分采用双层涂布设备中的其中一个模头的出料狭缝需要朝上，相较于出料狭缝朝向水平的模头，该出料狭缝朝上的模头难以实现安装维护，可表现为，出料狭缝朝向水平的模头可以设置在料带的一侧，操作空间较大，出料狭缝需要朝上的模头的上方存在有被涂覆的料带，部分操作空间被料带占用，导致工作人员部分活动受限，或者，且在模头的出料狭缝朝向水平的情况下，模头的盖板部分沿狭缝为开口翻开后，模头的料腔开口朝上，模头料腔内的残余浆料不易滴落，易于清理，而出料狭缝朝上的模头在盖板部分翻开后，模头的 料腔开口朝向侧方，模头料腔内的残余浆料会从料腔开口流落，又或者，在模头的出料狭缝朝向水平的情况下，模头上方的盖板上表面会安装有较多的零部件，这些零部件以自上而下的方式安装于模头即可，而在模头的出料狭缝朝上的情况下，这些零部件则是从侧方沿水平方向安装于模头盖板，在安装过程中需持续对零部件进行托举，不易安装。
有鉴于此，请参考图1-图5，本实施例提供了一种模头装置1000、涂布设备2000及涂布方法可以解决这一问题，接下来将对其进行详细的描述。
本发明的实施例提供了一种涂布设备2000，该涂布设备2000具体为一种双层涂布设备，其包括涂布设备本体2100、第二模头2200以及模头装置1000，第二模头2200安装于涂布设备本体2100上，模头装置1000位于涂布设备本体2100的一侧。
具体来说，第二模头2200用于对料带40的第一表面41进行涂布，第一模头400能够对料带40的第二表面42进行涂布，第一表面41和第二表面42位于料带40的相对两侧，第一表面41和第二表面42分别可以理解为料带40的上表面和下表面。
在本实施例中，料带40为集流体，当然了，在其他实施例中，料带40也可以为塑料薄膜或纸等。
需要说明的是，在涂布设备2000作业过程中，第二模头2200先对第一表面41进行涂布，然后第一模头400对已经完成第一表面41涂布的料带40进行第二表面42涂布。
该模头装置1000包括架体100、第一支座200、第二支座300以及第一模头400，第一支座200沿第一方向可滑动地连接于架体100，以沿料带的宽度方向上发生位移，第二支座300沿第二方向可滑动地连接于第一支座200，以在沿料带的厚度方向上发生位移。
其中，第二支座300可转动地连接于第一支座200，第一模头400安装于第二支座300，在本实施例中，第二方向和第一方向垂直，此处的第二方向可以理解为竖直方向，即，上下方向，第一方向可以理解为水平分布。
在需要对第一模头400进行安装维护时，可以首先使第二支座300相对于第一支座200滑动，使第一模头400向下移动并远离料带40的第二表面42，然后，将第一支座200相对于架体100沿第一方向滑动，在水平方向上远离料带40。
然后旋转第二支座300九十度，将第一模头400的出料夹缝60也朝水平方向，即，第一模头400的盖板位于料腔上方，此时，再进行安装维护，可以避免第一模头400内的零部件掉落，降低了安装维护难度。
具体来说，为了方便第一支座200的滑动，架体100上设有架体滑轨30，第一支座200安装在架体滑轨30上，同时，第一支座200可以在电机的驱动下，在架体滑轨30上沿第一 方向滑动。
需要说明的是，为了提高第一模头400涂布的精准度，涂布设备2000还包括偏移检测单元2300，偏移检测单元2300安装于涂布设备本体2100上，且用于检测料带40沿第一方向上的偏移，该偏移检测单元2300可以为图像传感器或者光电传感器。
偏移检测单元2300在检测到料带40发生偏移的情况下，可以将记载有偏移量的偏移数据反馈到用于驱动第一支座200滑动的电机，进而使第一支座200根据偏移量朝偏移方向相对于架体滑轨30滑动，这样，即使料带40未进行纠偏，也可以实现第一模头400对料带40进行正常涂布。
在本实施例中，模头装置1000还包括第一升降驱动件500以及滑动板体600，第一升降驱动件500安装于第一支座200，且第一升降驱动件500与第二支座300驱动连接，第一升降驱动件500用于驱使第二支座300沿第二方向靠近或远离架体100。
具体来说，其中，滑动板体600沿第二方向可滑动地连接于第一支座200，第二支座300可转动地连接于滑动板体600，第一升降驱动件500用于驱使滑动板体600靠近或远离第一支座200。
具体来说，该第一升降驱动件500为气缸，第一升降驱动件500可以带动滑动板体600在第二方向上移动，即，驱使第一模头400在上下方向大幅度移动。
为了实现第一模头400在第二方向上更加精准地移动，即控制第一模头400的出料夹缝60到料带40的第二表面42之间的距离，该模头装置1000还包括两个第二升降驱动件800，两个第二升降驱动件800分别安装在第一支座200的两侧，该第一支座200为U形板体。
其中，第二升降驱动件800包括水平驱动件810以及配合块820，水平驱动件810安装于第一支座200，水平驱动件810和配合块820连接，水平驱动件810用于驱使配合块820沿第一方向移动，该水平驱动件810可以是气缸，滑动板体600上安装有楔块900，楔块900和配合块820滑动连接，水平驱动件810在驱使配合块820沿第一方向移动的情况下，配合块820和楔块900相对滑动，以使滑动板体600相对于第一支座200沿第二方向滑动。
具体来说，楔块900具有楔块平面910和滑动斜面920，楔块平面910和滑动斜面920位于楔块900的相对两侧，且配合块820设有与和滑动斜面920滑动配合的斜面。
即，楔块平面910和滑动斜面920位于楔块900的上下两侧，配合块820和滑动斜面920滑动连接，以实现第一模头400在第二方向上的微调，即，第一模头400在上下方向的位移更加精确，需要说明的是，第一模头400在第二方向上的需要向上微调时，同时，也需要第一升降驱动件500对滑动板体600向上推动。
此外，在本实施例中，滑动板体600的数目两个，两个滑动板体600分别可滑动地连接在第一支座200的两侧，具体来说，滑动板体600可以通过滑轨与第一支座200连接，其中一个滑动板体600上安装有旋转驱动件50，该旋转驱动件50为驱动电机，旋转驱动件50和第二支座300连接，以用于驱动第二支座300转动。
在对第一模头400进行安装维护的过程中，为了避免第一支座200发生转动，影响安装维护，该模头装置1000还包括限位块700，限位块700为长方体结构，滑动板体600上设有滑槽601，该滑槽601和限位块700适配，限位块700沿第一方向可滑动地设置于滑槽601，其中，限位块700在第一方向上的长度大于滑动板体600在第一方向上的长度，以便于限位块700可以伸出滑槽601，且靠近第二支座300的侧面。
需要说明的是，该第二支座300为矩形板体结构，限位块700的数目为两个，滑槽601的数目也为两个，两个限位块700位于第二支的两侧，两个限位块700在滑动至预设位置的情况下，共同限制第二支座300转动，此处的预设位置可以理解为限位块700靠近旋转驱动件50的方向移动，直至限位块700的端部位于第二支座300的侧面，以能够对第二支座300进行限位。
为了方便限位块700的滑动，可以通过气缸(图未示)对限位块700沿第一方向驱动，即气缸和限位块700连接，以控制限位块700靠近或远离旋转驱动件50，在需要对第二支座300旋转，以进行第一模头400进行安装维护时，可以通过气缸带动限位块700远离旋转驱动件50，直至限位块700靠近旋转驱动件50的一端缩回滑槽601内。
此外，该涂布设备2000还包括报警系统(图未示)，该报警系统包括警报器以及位置检测传感器，位置检测传感器和报警器电连接，位置检测传感器可以安装在滑动板体600上，以对限位块700的位置进行检测，该位置检测传感器可以为光电传感器或图像传感器，报警器可以安装在架体100上或涂布设备本体2100上，当位置检测传感器检测到限位块700未滑动至预设位置的情况下，位置检测传感器可以将数据反馈给报警器，报警器报警，以提醒作业人员。
为了保证第一模头400位于料带40的下方，准确进行涂布作业，模头装置1000还包括限位板10，限位板10固定安装于架体100的一侧，具体来说，限位板10安装在架体滑轨30的一端，第一支座200在沿第一方向滑动至预设滑动位置的情况下，限位板10对第一支座200抵接，该预设滑动位置可以理解为第一模头400处于涂布工位。
其中，限位板10靠近第一支座200的一侧上设有凸块20，第一支座200靠近限位板10的一侧上设有凹槽，第一支座200在沿第一方向滑动至预设滑动位置的情况下，凸块20和凹 槽配合，以对第一支座200进行限位。
本发明的实施例还提供了一种涂布方法，采用上述的涂布设备2000，涂布方法包括：
控制第二模头2200对料带40的第一表面41进行涂布，控制第一模头400对料带40的第二表面42进行涂布，其中，料带40依次经过第二模头2200和第一模头400。
具体来说，在涂布设备2000作业过程中，第二模头2200先对第一表面41进行涂布，然后第一模头400对已经完成第一表面41涂布的料带40进行第二表面42涂布。
此时，第一模头400处于涂布工位，第一模头400的出料夹缝60朝上，第二模头2200的出料夹缝60为水平方向，即，第二模头2200的出料夹缝60朝左。
获取完成第一表面41涂布的料带40沿第一方向的偏移量，基于料带40沿第一方向的偏移量，控制所述第一支座200沿第一方向移动。
具体来说，在涂布设备2000进行涂布作业过程中，可以通过偏移检测单元2300获取完成第一表面41涂布的料带40沿第一方向的偏移量，并根据该偏移量控制第一支座200沿第一方向移动。
容易理解的是，偏移检测单元2300在检测到料带40发生偏移的情况下，可以将记载有偏移量的偏移数据反馈到用于驱动第一支座200滑动的电机，进而使第一支座200根据偏移量朝偏移方向相对于架体滑轨30滑动，这样，即使料带40未进行纠偏，也可以实现第一模头400对料带40进行正常涂布。
此外，在涂布设备2000进行涂布作业过程中，还可以通过获取位于第一模头400处的料带40弯曲状态，在第一模头400对料带40进行涂覆的状态下，控制第二支座300沿第二方向移动，以使第一模头400靠近或远离料带40的第二表面42。
具体来说，此处的弯曲状态可以理解为第一模头400上方的料带40向上凸起或向下凹陷。
需要说明的是，由于料带40的第一表面41先进行涂布，因此，位于第一表面41上的流体会下压料带40，使料带40凹陷，造成第一模头400在对第二表面42进行涂布时，出现料带40抖动问题，影响涂布质量。
因此，为了克服这一问题，需要使第一模头400的出料夹缝60出来的流体对第一模头400上方料带40的压力等于第一模头400上方料带40的第一表面41上流体的重力，进而使第一模头400上方料带40始终维持水平状态，即，第一模头400上方料带40既不上凸，也不凹陷，避免出现料带40抖动问题。
此处，可以通过在第一模头400处安装弯曲状态传感器(图未示)，例如将弯曲状态传感器安装在架体100上，弯曲状态传感器用于检测第一模头400上方的料带40弯曲状态。
然后，弯曲状态传感器将数据反馈至水平驱动件810，进行对滑动板体600在第二方向上的细微调节。
具体来说，驱使第一模头400在上下方向进行微调，以改变对第一模头400上方料带40的压力。
在第一模头400的料带40朝远离第一模头400的方向凸出的情况下，控制第二支座300沿第二方向移动，以使第一模头400远离料带40的第二表面42；在第一模头400的料带40朝靠近第一模头400的方向凸出的情况下，控制第二支座300沿第二方向移动，以使第一模头400靠近料带40的第二表面42。
容易理解的是，当第一模头400越远离料带40第二表面42，对第一模头400上方料带40的压力越小，当第一模头400越靠近料带40第二表面42，对第一模头400上方料带40的压力越大，因此，可以根据弯曲状态传感器获取的反馈数据，实现第一模头400的出料夹缝60出来的流体对第一模头400上方料带40的压力等于第一模头400上方料带40的第一表面41上流体的重力，维持第一模头400上方料带40的水平状态。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
