在电池的生产过程中，通常需要借助于涂布设备将制作好的糊状粘稠浆料涂覆在基材上。而在实际的涂布过程中，根据需要涂布后不同位置的涂层厚度，有时为了避免边缘鼓边等问题，会在浆料边缘形成削薄区，也就是由浆料所形成的涂层两侧边缘区域的厚度大于中间区域的厚度。浆料涂布之后厚度的精确程度直接影响电池的性能，因此亟需一种厚度调节精准的涂布模头。
 技术问题
本申请主要目的是提供一种涂布模头，旨在实现对涂层的厚度调节的基础上，可以对涂层的不同区域具有针对性的调节，提高对涂层的厚度调节的精准性。

 本发明的实施方式

申请人发现，在诸多的涂布工艺过程中，例如：在电池的生产过程中，通常需要借助于涂布设备将制作好的糊状粘稠浆料涂覆在基材上。而在实际的涂布过程中，根据需要涂布后不同位置的涂层厚度，有时为了避免边缘鼓边等问题，会在浆料边缘形成削薄区，也就是由浆料所形成的涂层两侧边缘区域的厚度大于中间区域的厚度。浆料涂布之后厚度的精确程度直接影响电池的性能，因此亟需一种厚度调节精准的涂布模头。
基于上述考虑，申请人为了实现对涂层的厚度进行，为此提出了一种新型的涂布模头。并在此基础之上，通过设置尺寸不同的调节件，对涂层的不同区域进行具有针对性的调节，以提高对涂层的不同区域的调节精度，更好的实现涂布的均匀性。
在本申请的一实施例中，请结合参考图1至图3，该涂布模头100包括模头主体10和至少两个调节件20。模头主体10设有连通外界的出料通道11，出料通道11具有出料口111，出料口111沿第一方向延伸，第一方向和出料通道11的出料方向相交的第一方向；至少两个调节件20设于模头主体10，并沿第一方向分布，每一个调节件20的至少部分可在出料通道11内沿第二方向移动，第二方向垂直于出料方向和第一方向，且至少两个调节件20的沿第一方向的尺寸不相同。
上述的模头主体10可以作为涂布模头100的主体结构，以用于形成出料通道11和安装至少两个调节件20等。其中，出料通道11还具有进料口，待涂覆的浆料可以从该进料口进入到出料通道11内，之后从出料口111被挤出至基材上，即可完成对基材的涂布工艺。由于被涂覆的基材通常具有较大的宽度，因此模头主体10上的出料口111可以沿第一方向延伸成长条状，也即沿基材的的宽度方向延伸设置。此时，模头主体10对应的也为一长条状结构，其长度方向可以是第一方向，宽度方向可以是出料通道11的出料方向，高度方向可以是调节件20的移动方向—第二方向。当然，本申请不限于此，于其他实施例中，模头主体10大致为一方体结构也是可以的，也即模头主体10在第一方向上的尺寸和在出料方向上的尺寸相同。
调节件20可以用于对出料通道11的出料流量进行调节，具体而言，调节件20可以在移动时，是有至少部分位于出料通道11内，且调节件20的移动方向还是垂直出料方向和第一方向，也即沿模头主体10的高度方向移动。如此在调节件20移动过程中，可以调整该处所能供浆料通过的通道截面，例如：在调节件20向下移动时，出料通道11对应该调节件20的区域的通道截面减小，使得通过该处的浆料流量也就减小，最终实现基材上对应该调节件20的涂覆区域的涂层厚度也就可以得到减小。而在调节件20调节件20上下移动时出料通道11对应该调节件20的区域的通道截面增大，使得通过该处的浆料流量也就增大，最终实现基材上对应该调节件20的涂覆区域的涂层厚度也就可以得到增加。因此，通过驱动不同的调节件20移动，即可实现基材上对应区域的涂层的厚度得到调整。其中，调节件20可以仅部分设置在出料通道11内；当然，调节件20也可以是整体均设置在出料通道11。亦或者是，调节件20整体均设置在出料通道11之外，保证调节件20在后续移动时，能够进入到出料通道11内移动以实现对浆料的流量进行调节也是可以的。此外，调节件20的移动可以是由操作人员手动驱动的方式，当然也可以是通过设置气缸或者直线模组等自动驱动的方向，本申请对此不作具体限定。另外，调节件20的数量可以为两个、三个或者是更多个，保证在第一方向上依次分布即可。而调节件20可以为块状结构、板体结构或者是柱体结构等，能够在移动过程中实现对出料通道11的出料流量进行调节即可。
本方案中的涂布模头100在使用时，浆料可以从出料通道11流至出料口111，并在从出料口111挤出后即可涂覆到待涂覆的基材上，以完成对基材的涂布。并且，本方案中的涂布模头100的至少两个调节件20在第一方向上的尺寸不相同，使得在对涂层的不同区域进行调节时，可以根据对应该区域的调节件20来进行针对性的性的调节，例如：针对涂层的中间主要部分的区域的调节，可以采用尺寸相对较大的调节件20对应进行调节；而针对涂层的边缘部分的区域的调节，可以采用尺寸相对较小的调节件20对应进行调节，实现通过不同的长度尺寸的调节件20对不同区域的涂层厚度进行更加精准的调节。因此，本方案中的涂布模头在实现对涂层的厚度调节的基础上，可以对涂层的不同区域具有针对性的调节，从而提高了对涂层的厚度调节的精准性。。
请结合参考图3和图4，在本申请的一实施例中，出料通道11在第一方向上具有主膜区域112和边缘区域113，边缘区域113位于主膜区域112的边缘，主膜区域112和边缘区域113内均设有调节件20。
主膜区域112也就是涂层中间部位所对应的位置，以通过出料通道11在主膜区域112的出料来形成涂层的中间部位。边缘区域113也就是涂层边缘部位所对应的位置，以通过出料通道11在边缘区域113的出料来形成涂层的边缘。其中，涂层在第一方向上的相对两侧（也可以说是涂层的宽度方向上）均具有边缘，因此主膜区域112在第一方向上的相对两侧均可以形成为边缘区域113。
在本实施例中，通过在主膜区域112和边缘区域113内均设置有调节件20，使得除了可以对边缘区域113内的涂层的厚度进行调节，还可以对主膜区域112内的厚度进行调节，从而提高了对涂层不同区域的厚度调节的灵活性。当然，需要说明的是，本申请不限于此，于其他实施例中，也可以是边缘区域113内设置有调节件20。
请结合参考图3和图4，在本申请的一实施例中，在第一方向上，位于主膜区域112内的调节件20的长度值和位于边缘区域113内的调节件20的长度值设置为不相同。
主膜区域112内的调节件20的长度值和边缘区域113内的调节件20的长度值设置为不相同，也就是说，主膜区域112内的调节件20在第一方向上的长度尺寸可以根据主膜区域112在第一方向上的长度尺寸进行适应性设置，边缘区域113内的调节件20在第一方向上的长度尺寸可以根据边缘区域113在第一方向上的长度尺寸进行适应性设置，使得主膜区域112内的调节件20的长度和边缘区域113内的调节件20的长度存在差异。
在本实施例中，通过对主膜区域112内的调节件20的长度和边缘区域113内的长度进行分别设置，可以更好的对应主膜区域112和边缘区域113各自的区域大小来适应性的设置调节件20的长度尺寸，以便对主膜区域112和边缘区域113具有更加针对性的调节。当然，需要说明的是，本申请不限于此，于其他实施例中，位于主膜区域112内的调节件20的长度值和位于边缘区域113内的调节件20的长度值设置为相同也是可以的。
请结合参考图3和图4，在本申请的一实施例中，在第一方向上，位于主膜区域112内的调节件20的长度值大于位于边缘区域113内的调节件20的长度值。
位于主膜区域112内的调节件20的长度值大于位于边缘区域113内的调节件20的长度值，也就是说，在位于主膜区域112内的调节件20和位于边缘区域113内的调节件20的数量均为一个时，该主膜区域112内的调节件20的长度尺寸相较于边缘区域113内的调节件20的长度尺寸更大。而在主膜区域112内和边缘区域113内均设置有多个调节件20时，主膜区域112内长度最小的调节件20的长度尺寸大于边缘区域113内长度值最大的调节件20的长度尺寸。
在本实施例中，将主膜区域112内的调节件20的长度值设置的相对较大，边缘区域113内的调节件20的长度值设置的相对较小，使得可以与主膜区域112在第一方向上的尺寸大于边缘区域113的尺寸的情况相适配。此时，可以通过长度尺寸相对较大的调节件20实现对在第一方向上具有相对较大尺寸的主膜区域112内的涂层进行快速调节，且方便保证主膜区域112内的涂层厚度具有较好的一致性。同时，可以通过长度尺寸相对较小的调节件20实现对在第一方向上具有相对较小尺寸的边缘区域113涂层厚度进行更加细致的调整，也即对边缘区域113内的涂层进行进一步地区域划分，以便将边缘区域113内的涂层更好的调整至所需要的范围内。当主膜区域112内的调节件20设置有多个，边缘区域113内的调节件20也设置有多个时，主膜区域112内长度值最小的调节件20的长度值也大于边缘区域113内长度值最大的调节件20的长度值。这样，对于尺寸小的边缘区域113可以更精确的控制其厚度，减少边缘鼓起的问题。
进一步地，为了实现对和边缘区域113对应的涂层可以进行更加细致的调节，在一实施例中，位于主膜区域112内的调节件20的数量可以小于位于边缘区域113内的调节件20的数量。此时，位于主膜区域112内的调节件20的数量相对较少，可以尽可能的较少因为频繁调节引起涂层重量波动，能够更利的保证主膜区域112内的涂层厚度的一致性。而位于边缘区域113内的调节件20的数量相对较多，可以进一步地对边缘区域113内的不同位置的涂层进行更加细致的调节。
请参考图4，在本申请的一实施例中，主膜区域112内设置有多个调节件20，在第一方向上，位于主膜区域112内的各个调节件20的长度值设置为相同或者部分相同。
位于主膜区域112内的各个调节件20的长度值设置为相同或者部分相同，也就是说，主膜区域112内的各个调节件20可以具有一致的长度值，也可以是仅有其中的两个调节件20具有一致的长度值。
在本实施例中，将主膜区域112内的各个调节件20的长度尺寸设置为相同，可以提高该部分各个调节件20的规整一致性，以便提高对其加工成型的便利性。而将部分调节件20的长度尺寸设置为相同，即可以使得部分调节件20相对具有一致性，以方便对其进行加工。同时，通过配合长度尺寸不同的调节件20还可以方便主膜区域112内的几个调节件20的总体长度和主膜区域112内的长度相适配。当然，需要说明的是，本申请不限于此，于其他实施例中，位于主膜区域112内的各个调节件20的长度值也可以设置为不相同。
请参考图4，在本申请的一实施例中，边缘区域113内设置有多个调节件20，在第一方向上，位于边缘区域113内的各个调节件20的长度值设置为相同。
位于边缘区域113内的各个调节件20的长度值设置为相同，也就是说，边缘区域113内的各个调节件20可以具有一致的长度值。
在本实施例中，将边缘区域113内的各个调节件20的长度齿设置为相同，同样可以提高该部分各个调节件20的一致性，以便提高对其加工成型的便利性。当然，需要说明的是，本申请不限于此，于其他实施例中，在第一方向上，位于边缘区域113内的各个调节件20的长度值可以设置为不相同或者是仅部分相同。
请结合参考图1和图2，在本申请的一实施例中，涂布模头100还包括至少两个驱动组件30，至少两个驱动组件30均设于模头主体10的外表面，驱动组件30用于驱动调节件20移动。
驱动组件30可以用于驱动调节件20移动，且是每一个驱动组件30驱动对应的一个调节件20移动的。而驱动组件30设置在模头主体10的外表面，也即设置在模头主体10外侧而使得该驱动组件30可以显露于外界。其中，该驱动组件30可以为上文所描述的气缸或者直线电机，以实现对调节件20的自动驱动；也可以是如下文所描述的具有螺纹段331或者螺纹孔41的一结构，通过螺纹段331和螺纹孔41配合实现对调节件20的手动驱动。
在本实施例中，将驱动组件30设置在模头主体10的外表面，方便对其进行驱动调节。同时，也可以方便后续对其进行维修等操作。当然，需要说明的是，本申请不限于此，于其他实施例中，驱动组件30也可以是设置在模头主体10内，也就是设置在连通于出料通道11的一容置空间内。
请参考图2和图8,在本申请的一实施例中，涂布模头100还包括连接件40，连接件40连接驱动组件30和调节件20，模头主体10还设有连通出料通道11的连通孔12，连接件40穿过连通孔12与调节件20连接。
连通孔12可以连通出料通道11和外界，进而方便连接件40的穿过，而连接件40的一端可以连接于驱动组件30，相对的另一端可以连接于调节件20。此时，在驱动组件30驱动连接件40移动后，即可带动与该连接件40连接的调节件20进行一端，从而实现驱动组件30对调节件20的间接驱动。
在本实施例中，通过连接件40对驱动件33和调节件20进行连接，以实现驱动件33和调节件20之间的间接连接，可以使得位于模头主体10外的驱动件33，以及位于模头主体10内的调节件20均无需因为两者之间的较大的距离的存在而导致设置的较为复杂。当然，需要说明的是，本申请不限于此，于其他实施例中，驱动组件30的部分结构穿过连通孔12，以连接于调节件20也是可以的。亦或者是，调节件20的部分结构穿过连通孔12，以连接于驱动组件30也是可以的。
在本申请的一些实施例中，可以是多个连接件40设置于一个连通孔12中，便于调整调节件20尺寸以适应不同的涂布垫片宽度。而且，此时也使得连通孔12的数量非常少，进而有利于提高对模头主体10加工成型的便利性。
请参考图2，在本申请的一实施例中，驱动组件30包括安装件31和驱动件33，安装件31设于模头主体10；驱动件33连接于安装件31，并和连接件40连接，驱动件33可驱使连接件40移动，以带动调节件20移动。
安装件31可以用于提供安装位，以便安装驱动件33。同时，安装件31还可以用于和模头主体10连接，以实现驱动组件30在模头主体10上的安装。其中，该安装件31也可以为一板体结构，或者为一柱体结构，亦或者是由多个板体围合形成的架体结构等，本申请对安装件31的具体结构形状不作限定，能够用于安装驱动件33，且连接模头主体10即可。驱动件33可以用于驱动连接件40移动，其可以为如上文描述的气缸、线性电机或者是具有一螺纹段331或者螺纹孔41的结构。
在本实施例中，通过安装件31可以和模头主体10进行连接，使得方便在该安装件31设置对应的连接结构，以便提高驱动组件30在模头主体10上的安装的便利性。当然，需要说明的是，本申请不限于此，于其他实施例中，驱动件33也可以是直接设置在模头主体10上。
请结合参考2、图5以及图7，在本申请的一实施例中，安装件31设有安装孔311，驱动件33可转动地穿设于安装孔311，且驱动件33靠近调节件20的一端形成有螺纹段331和螺纹孔41的其中之一；连接件40远离调节件20的一端形成有螺纹段331和螺纹孔41的其中之另一，螺纹段331插入螺纹孔41内，以在驱动件33旋转时带动连接件40移动。
驱动件33设置有螺纹段331和螺纹孔41的其中之一，连接件40设置有螺纹段331和螺纹孔41的其中之另一。使得驱动件33在进行旋转时，由于螺纹段331和螺纹孔41的配合，同时连接件40因为连接有调节件20，使得该连接件40也无法跟随驱动件33进行旋转，进而可以沿其轴向方向进行移动，并带动与该连接件40连接的调节件20进行移动。其中，可以是驱动件33上设置有螺纹段331，连接件40上设置有螺纹孔41。当然也可以是驱动件33上设置有螺纹孔41，连接件40上设置有螺纹段331。而连接件40可以为一员柱体结构，并沿调节件20的移动方向延伸设置。
在本实施例中，驱动件33和连接件40之间通过螺纹连接，使得驱动件33的结构较为简单，从而可以提高对其制造的便利性。同时，也使得驱动件33和连接件40之间为纯机械结构传动，也就不会涉及电路和气路等，从而有利于提高涂布模头100在使用过程中的安全性。
请参考图7，在本申请的一实施例中，当驱动件33设有螺纹段331，连接件40设有螺纹孔41时；安装件31还设有导向孔313，导向孔313连通于安装孔311，并和安装孔311呈共轴线设置，连接件40设有螺纹孔41的一端插入导向孔313内。
安装孔311可以说是设置在安装件31远离连接件40的一侧，那么导向孔313可以说是设置在安装件31靠近连接件40的一侧，且两者呈共轴线并相连通。驱动件33具有螺纹段331的一端可以伸入到导向孔313，同样的连接件40设置有螺纹孔41的一端也可以伸入到导向孔313内，并与螺纹段331螺纹配合。此时，在驱动件33旋转而带动连接件40移动时，该连接件40可以在导向孔313内移动，而导向孔313的形状可以和连接件40的形状相适配，也就实现对该连接件40的移动具有导向作用。
在本实施例中，通过该导向孔313可以对连接件40的移动起到导向作用，换句话说也就是对调节件20的移动具有导向作用，以便调节件20可以对出料通道11的出料流量进行稳定且有效的调节。
请参考图2，在本申请的一实施例中，出料通道11的内壁设有安装槽114，安装槽114连通于连通孔12，调节件20设于安装槽114内。
安装槽114可以设置在出料通道11的第二方向上的相对两个通道内壁的其中之一，进而通过该安装槽114来容置调节件20。其中，该安装槽114可以沿第一方向延伸设置，至少两个调节件20均可以设置在该安装槽114内。
在本实施例中，通过该安装槽114可以给予调节件20安装空间，以便提高对调节件20设置的便利性。而且，也可以使得该调节件20可以设置的具有相对较大的体积，以提高调节件20的强度而方便调节件20后续可以稳定的进行调节工作。
请参考图2，在本申请的一实施例中，涂布模头100还包括密封件50，密封件50设于调节件20和安装槽114连通于连通孔12的槽壁之间。
密封件50可以用于对调节件20和安装槽114连通于连通孔12的槽壁之间进行密封，其中，该密封件50的材质可以橡胶或者硅胶等，以使其具有一定的弹性，在被调节件20挤压后发生弹性形变而紧贴于调节件20和安装槽114连通于连通孔12的槽壁之间。此外，密封件50的数量可以为一个，以对至少两个调节件20和安装槽114连通于连通孔12的槽壁之间进行密封。当然，该密封件50的数量也可以是对应调节件20的数量，此时一个密封件50对一个调节件20和安装槽114连通于连通孔12的槽壁之间进行密封。
在本实施例中，通过密封件50的密封作用，使得即便有浆料进入到安装槽114内，也可以通过该密封件50的密封作用避免该浆料进一步地进入到渗透到连通孔12内。
请结合参考图1和图3，在本申请的一实施例中，在第一方向上，每一个驱动组件30中的安装件31的长度值和对应的调节件20的长度值相同。
每一个驱动组件30中的安装件31的长度值和对应的调节件20的长度值相同，也就是说，安装件31和调节件20一一对应设置，且呈对应的安装件31在第一方向上长度尺寸和调节件20在第一方向上的长度尺寸一致。
在本实施例中，将安装件31和调节件20呈一一对应，且长度尺寸也设置为相同，可以方便保证设置在安装件31上的驱动件33和调节件20也可以准确对应，进而实现驱动件33对调节件20可以有效的起到调节作用。同时，如此设置，也方便操作人员根据对应关系来快速判断出所需要操作的驱动件33，以实现对需要调节的调节件20进行相应的调节。
在本申请的一实施例中，各个驱动组件30中的安装件31均可拆卸地设于模头主体10。
安装件31可拆卸地设于模头主体10，也就是说安装件31可以从模头主体10上拆卸下来。
在本实施例中，安装件31可以进行拆卸，使得可以更换具有不同尺寸的调节件20来进行使用，以方便涂布设备可以适用各种尺寸规格的涂层需求，也即适用不同宽度的涂层需求，从而有利于提高涂布设备使用的灵活性。同时，在驱动组件30和调节件20发生损坏时，可以将其拆卸下来进行维修更换，从而提高对其维修更换的便利性。
请结合参考图1、图2以及图5，在本申请的一实施例中，涂布模头100还包括固定架60，固定架60包括固定座61和压紧板63，固定座61设于模头主体10；压紧板63可拆卸地连接于固定座61，并和固定座61相配合夹持固定各个驱动组件30中的安装件31。
固定座61和压紧板63均可以为沿第一方向延伸设置的长条状结构，以实现对至少两个安装件31的夹持安装。其中，固定座61和压紧板63可以是夹持安装件31的部分，即驱动件33可以设置在安装件31中未被夹持的部分。当然，该固定座61和压紧板63也可以是夹持安装件31的全部。
在本实施例中，通过固定架60和压紧板63对安装件31进行夹持安装，使得无需在安装件31上设置对其进行安装的连接结构，从而有利于保证各个安装件31的强度。而且，也可以将各个安装件31安装于固定座61上后，可以一次性的将该部分结构安装到模头主体10上，从而有利于提高对该部分结构安装的便利性。当然，本申请不限于此，于其他实施例中，各个安装件31直接安装于模头主体10上也是可以的。
请结合参考图5和图6，在本申请的一实施例中，固定座61和压紧板63围合形成容置腔65，安装件31容纳于容置腔65内；固定座61设有连通容置腔65的第一避让孔611，连接件40远离调节件20的一端穿过第一避让孔611，以连接于驱动件33；压紧板63设有连通容置腔65的第二避让孔631，驱动件33远离连接件40的一端穿过第二避让孔631，以延伸至外界。
容置腔65可以用于容置各个驱动组件30中的安装件31，因此在第一方向上，容置腔65的长度尺寸和各个安装件31的总体长度尺寸相同，以避免安装件31沿第一方向移动而影响安装的准确性和稳定性。第一避让孔611可以供连接件40穿过，以便连接件40和驱动件33进行连接。第二避让孔631可以供驱动件33穿过，以便驱动件33的部分显露于外界而方便操作人员对其操作。
在本实施例中，通过容置腔65可以对安装件31具有适配容置效果，从而有利于提高对各个安装件31安装的稳定性，以便后续驱动组件30对调节件20进行稳定且有效的驱动工作。而且，在安装各个安装件31，将其逐一安装于容置腔65内，即可实现对安装件31的快速定位，从而有利于提高驱动组件30安装的便利性。
请参考图2，在本申请的一实施例中，涂布模头100包括第一模头13和第二模头15，第二模头15可拆卸地连接于第一模头13，并和第一模头13围合形成出料通道11，驱动组件30和连通孔12设于第一模头13和/或第二模头15。
第一模头13和第二模头15可以在第二方向上依次分布，并在连接成整体后，可以围合形成出料通道11。而第一模头13和第二模头15可拆卸连接，则是指第一模头13和第二模头15在连接成整体后，仍然可以将两者拆卸分开。其中，第一模头13和第二模头15可以是通过螺钉连接、卡扣连接、磁吸固定等任意方式，保证实现两者可以进行拆卸分开即可。而驱动组件30和连通孔12设于第一模头13和/或第二模头15，也就是说，可以是仅在第一模头13和第二模头15中的一者上设置有驱动组件30和连通孔12，当然也可以是在第一模头13和第二模头15中的两者上均设置有驱动组件30和连通孔12。
在本实施例中，将模头主体10拆分为第一模头13和第二模头15，使得两者可以分开独立制造，之后再组装成整体，以围合形成出料通道11。而拆分成的第一模头13和第二模头15的结构相较于整体结构均可以得到简化，从而有利于提高对模头主体10制造的便利性。同时，第一模头13和第二模头15可拆卸连接，也使得调节件20在发生损坏或者出料通道11出现堵塞等情况时，可以将第一模头13和第二模头15拆卸分开，以提高对调节件20和出料通道11维护的便利性。
请结合参考图2和图8，在本申请的一实施例中，在出料通道11在出料方向上，出料通道11包括依次连通的主体段115和出口段116，出口段116远离主体段115的一端具有出料口111；出口段116的通道截面面积小于主体段115的通道截面面积，调节件20的至少部分可于出口段116内移动。
主体段115也可以是出料通道11的中间主要部分，而出口段116则相较于主体段115位于出料通道11的下游，在主体段115内的浆料进入到出口段116内后，即可经出口段116远离主体段115的一端的出口挤出至基材上。其中，出口段116的通道截面面积小于主体段115的通道截面面积，可以是出口段116在第二方向上的两通道内壁之间的尺寸小于主体段115在第二方向上的两通道内壁之间的尺寸。
