如图1所示，本发明提供一种激光切割极耳的辅助牵引装置的优选实施例。 
一种激光切割极耳的辅助牵引装置，设置在极片带运输装置的激光切割极耳区域320处，一激光器310对准激光切割极耳区域320，将通过极片带运输装置运输至此区域的极片带10进行激光加工，实现激光切割极耳操作。例如，通过极片带运输装置将极片带10的一待加工区域运输到激光切割极耳区域320中，进行激光切割极耳，完成后再将下一个待加工区域运输到激光切割极耳区域320中，反复不断重复运输及激光加工。但是，由于在激光加工或运输过程中，会产生抖动和废料不能有效排出问题，因此需要设置辅助牵引装置，辅助极片带10运输以及在加工过程中拉紧。
在本实施例中，所述辅助牵引装置包括沿着极片带10运输方向设置的前吸附组件100和皮带吸附牵引组件200，且激光切割极耳区域320设置在所述前吸附组件100和皮带吸附牵引组件200之间；其中，所述前吸附组件100包括吸附贴紧极片带10的吸附块110，所述皮带吸附牵引组件200包括沿着极片带10运输方向同步运转的多个皮带260，以及为各皮带260缝隙处提供负压的吸附模块。
具体的，在极片带10运输方向上，前吸附组件100设置在极片带10切入位置处，皮带吸附牵引组件200设置在极片带10切出位置处，极片带10在极片带运输装置运输下，经过极片带10切入位置并穿过激光切割极耳区域320处，后从极片带10切出位置处切处，在穿过激光切割极耳区域320处时，通过激光器310进行激光切割极耳操作。在激光切割极耳的过程中，设置辅助牵引装置，有效解决极片在切割过程中的抖动，以及废料疏导问题。
以及，极片带10在极片带运输装置的运输下，在切入位置处靠近至前吸附组件100，被吸附块110吸附贴紧，再配合皮带吸附牵引组件200，使极片带10在激光切割极耳区域320处进行激光加工时，减弱甚至消除抖动，提高焊接精准性。以及，极片带10在极片带运输装置的运输下，在切出位置处前通过皮带吸附牵引组件200，吸走切割后落在皮带260上的粉尘，避免废料不能有效排出问题。
如图2所示，本发明提供前吸附组件的较佳实施例。
所述前吸附组件100还包括负压管120，所述负压管120分别与吸附块110上的多个吸附孔111和外部真空组件连接，外部真空组件通过负压管120为吸附孔111提供负压，避免粉尘堆积；其中，所述极片带10在经过前吸附组件100时被吸附孔111吸附并贴紧吸附块110。具体地，所述吸附块110还包括通道，所述通道分别与负压管120和吸附孔111连通，外部真空组件通过负压管120、通道为吸附孔111提供负压。其中，多个所述吸附孔111阵列设置在吸附块110的一端面上；所述吸附块110的上端面设有安装结构，如腰型孔，便于使前吸附组件100安装在一支架700上，实现固定。
吸附块110表面负压使得极片带10紧贴吸附块110表面，保证极片带10在激光切割极耳区域320不会抖动，特别是激光器310发射激光加工极片带10时。
如图3和图4所示，本发明提供皮带吸附牵引组件的较佳实施例。
所述皮带吸附牵引组件200还包括立板支柱220、主动轴232、从动轴231和驱动模块240，所述主动轴232和从动轴231分别设置在立板支柱220的两端，且平行设置，所述皮带260套设在主动轴232和从动轴231之间以进行同步运转，所述立板支柱220作为皮带吸附牵引组件200的主体支架，所述驱动模块240与主动轴232连接并带动主动轴232转动。
具体地，所述驱动模块240驱动主动轴232在立板支柱220的一端处转动，通过皮带260带动另一端的从动轴231一起转动，实现皮带260在立板支柱220朝主动轴232的滚动方向运动，并在皮带吸附牵引组件200的前端面形成负压区域。优选地，多根皮带260并排设置在主动轴232和从动轴231之间，任一相邻皮带260之间设有缝隙，吸附模块在立板支柱220内形成负压环境，使皮带吸附牵引组件200的前端面通过皮带260的缝隙形成负压区域。不仅通过皮带260对极片带10进行吸附，提高激光切割极耳区域320的激光加工操作时极片带10的稳定性，还能时极片带10与加工后的废料分离。
在本实施例中，皮带260优选为圆皮带。圆带为带传动中带的一种，其截面形状为圆形。
在本实施例中，所述吸附模块包括真空罩212，所述真空罩212的罩口套设在皮带260的非吸附端面处，外部真空组件与真空罩212的负压口211连通并提供负压。具体地，外部真空组件开启提供负压，通过真空罩212的负压口211使真空罩212内形成负压，使罩口皮带260的非吸附端面处形成负压，外部空气经过皮带260吸附端面处的缝隙流入，并在皮带260非吸附端面处的缝隙进入真空罩212中，以吸附经过皮带260吸附端面处的极片带10；同时，吸附激光加工后的废料和碎屑，使其脱离极片带10。
进一步地，所述皮带吸附牵引组件200还包括设置在立板支柱220上且靠近极片带10切出处的破真空杆251，所述破真空杆251包括朝向皮带260设置并吹气的吹气孔2511。通过破真空杆251吹气孔2511吹出的气流，在靠近极片带10切出处使被吸附的废料和碎屑吹出，以防废料和碎屑绕着皮带260绕到非吸附端面处，阻碍负压气流的通过。优选地，所述破真空杆251设设置有多个吹气孔2511，吹气孔2511均朝向极片带10切出处设置，其中破真空杆251通过通气口252与外部吹起装置连通，以实现吹气孔2511的出气；以及，吹气大小可调，满足不同厚度大小的极片带10或加工废料的大小，可防止废料跟随皮带260卷到后方，保证废料落料平顺。
在本实施例中，所述皮带260的运转速度大于极片带10的运输速度。可进一步通过皮带260与极片带10的摩擦，使极片带10的废料和碎屑脱落，提高废料和碎屑的脱落效率。
在本实施例中，驱动模块240通过齿轮的啮合转动控制主动轴232转动。如驱动模块240的电机转轴设有一齿轮251，主动轴232的外侧也设有齿轮252，两齿轮相互啮合，通过驱动模块240对主动轴232转动。
如图5、图6和图7所示，本发明提供小辊组件400的较佳实施例。
所述辅助牵引装置还包括设置在靠近极片带10切入处的小辊组件400，所述小辊组件400的小辊压向切入的极片带10；以及，所述小辊组件400包括位置可调的调整座410，所述小辊转动设置在调整座410上。
具体地，通过调整调整座410的位置，即前后位置，调整小辊压向极片带10的位置，使极片带10从极片带运输装置到前吸附组件100之间产生一偏移角度（即极片带运输装置的切出方向和前吸附组件100的切入方向所形成的夹角，优选3至5度），以增加极片带10的紧绷性，预防波浪状的产生，使在激光切割极耳区域320更平整，更有张力，从而提高激光加工精准性能。其中，小辊组件400转动设置在调整座410上，优选设置在其端边出，作为最端面位置；以及，小辊组件400应包括小辊420、轴芯和轴承，所述轴承设置在调整座410的两端孔位411，小辊420固定在轴芯上，且通过轴芯固定在轴承的内轴，以实现自传。
优选地，调整座410位置可调设置在支架700上。其中，调整座410上设置有腰型孔412，通过腰型孔412与安装螺钉的位置，以调整调整座410相对于支架700的位置。
如图8和图9所示，本发明提供挡光组件600的较佳实施例。
所述辅助牵引装置还包括设置在极片带10非吸附面一侧的挡光组件600；以及，所述挡光组件600包括防护罩610，设置在防护罩610内部的挡光散热块620，以及设置在挡光散热块620和防护罩610之间的隔热垫630。
具体地，极片带10经过辅助牵引装置。一侧面作为吸附面被辅助牵引装置吸附，同时激光器310激光朝向极片带10的吸附面激光加工，为了对激光（穿过极片带10的激光）进行防护，防止人员直接面对激光或受激光的光影响，在极片带10非吸附面一侧的挡光组件600，优选地，激光器310、激光切割极耳区域320和挡光组件600构成一直线。其中，防护罩610为挡光组件600主体，不仅作为主体构架，还对挡光散热块620进行隔绝，挡光散热块620设置在内部（可部分设置在内部，也可以全部设置在内部），对激光的光线进行阻挡，还对激光的热进行吸收及散热，避免热量集中，损坏挡光组件600，隔热垫630设置在挡光散热块620和防护罩610之间，防止挡光散热块620的热量导到防护罩610中，避免人员误接触。
激光在切割极片带10后的能量可对人员皮肤造成灼伤，为防止人员无意中置于激光切割极片带10后的危险区域中，通过挡光散热块620进行保护；因激光的固有特性，能量高度集中、连续工作，所以挡光散热块620的材料不能只考虑熔点，要和材料的散热性综合考量，例如铝的高热传导率以及较高的熔点；防护罩610防止人员手直接接触到挡光散热块620，实现与挡光散热块620的隔绝。
如图5和图6所示，本发明提供激光切割极耳系统的优选实施例。
一种激光切割极耳系统，包括极片带运输装置、激光器310和辅助牵引装置，极片带运输装置带动极片带10运输至激光切割极耳区域320处；激光器310对激光切割极耳区域320处的极片带10进行极耳切割；辅助牵引装置设置在极片带运输装置的激光切割极耳区域320处。
具体地，所述极片带运输装置包括运输极片带10的切入辊510和切出辊520，所述辅助牵引装置的前吸附组件100和皮带吸附牵引组件200设置在切入辊510和切出辊520之间。极片带10从切入辊510切入，并依次经过前吸附组件100、激光切割极耳区域320和皮带吸附牵引组件200，再从切出辊520切出。
若不设置前吸附组件100和皮带吸附牵引组件200，极片带10在切入与切出位置上会出现抖动和废料不能有效排出问题，特别是在激光切割极耳区域320进行激光加工过程中，抖动会影响激光加工，是导致激光切割极片带10无法稳定连续生产的主要原因。通过前吸附组件100和皮带吸附牵引组件200，使激光切割极片带10时，能稳定连续的运行，避免抖动和废料不能有效排出问题，推动激光切割极耳设备大批量商用的基础，使锂电池行业快速发展。
以上所述者，仅为本发明最佳实施例而已，并非用于限制本发明的范围，凡依本发明申请专利范围所作的等效变化或修饰，皆为本发明所涵盖。
