Description

换卷装置 技术领域
本申请涉及锂电池设备技术领域，特别涉及一种换卷装置。
背景技术
在采用卷绕工艺生产锂电池的过程中，需要将阴极片、隔膜及阳极片进行卷绕形成电芯。在极片进入卷绕装置进行卷绕之前，需要先将极耳焊接在极片的特定位置，再使极耳随极片一同卷绕。
极耳焊接设备一般采用卷料放卷的方式提供极耳，放卷的极耳料带经裁切后形成极耳片料，再与极片进行焊接。为了保证生产过程的连续性，当一个极耳料卷用完时，需要立即更换新的极耳料卷，即换卷。在极耳换卷的过程中，工作料带及备用料带需要经过切断、对齐及贴胶带等一系列工序。目前，部分工序还需要人工操作，从而导致换卷装置的换卷效率较低。

请参阅图1至图3，本申请一个实施例中的换卷装置10包括放卷机构100、固定机构200、接带机构300及贴胶机构400。
放卷机构100包括第一放卷组件110及第二放卷组件120，第一放卷组件110及第二放卷组件120的结构相同，均可以包括放卷轴，放卷轴用于安装料卷并向下游放卷输出料带，料带可以是极耳料带、极片料带等生产过程中需要进行放卷的料带，本实施例中的料带为极耳料带。
第一放卷组件110及第二放卷组件120的下游一般还设置有张力调节组件(图未标)及若干过辊(图未标)，张力调节组件用于在放卷过程中对料带进行缓存或释放，从而维持料带的张力，过辊则能够改变料带的输送方向。具体在本实施例中，第一放卷组件110及第二放卷组件120放卷的料带经过若干过辊的导向后能够沿大致水平的方向输送，且料带的表面与水平面大致平行。
第一放卷组件110及第二放卷组件120放卷输出的料带能够交替作为工作料带21及备用料带22。即，第一放卷组件110放卷输出的料带作为工作料带21时，第二放卷组件120放卷输出的料带作为备用料带22；而第一放卷组件110 放卷输出的料带作为备用料带22时，第二放卷组件120放卷输出的料带则作为工作料带21。工作料带21指的是放卷机构100放卷输出后向下游输送，并最终裁切加工成片料(如，极耳片料)的料带，而备用料带22则暂时不向下游输送并加工，仅作为工作料带21放卷完毕后的补充。
固定机构200包括第一固定组件210及第二固定组件220，固定机构200位于放卷机构100的下游，第一固定组件210及第二固定组件220能够分别固定由第一放卷组件110及第二放卷组件120放卷输出的料带。固定机构200可通过吸附、夹持等方式对料带进行固定。具体在本实施例中，第一固定组件210包括夹爪气缸及固定于夹爪气缸的驱动端的两个固定夹爪，夹爪气缸能够带动两个固定夹爪靠拢或张开，以对第一放卷组件110放卷输出的料带进行夹紧或释放。第二固定组件220与第一固定组件210的结构相同，故不再赘述。
接带机构300包括第一裁切组件310及第一定位组件320，接带机构300位于固定机构200的下游，放卷机构100放卷输出的工作料带21能够依次途经固定机构200及第一定位组件320。第一裁切组件310能够切断由固定机构200(既可以是第一固定组件210，也可以是第二固定组件220)及第一定位组件320共同固定的工作料带21。具体的，第一裁切组件310一般采用上、下切刀相配合的方式将工作料带21切断，而第一定位组件320也可采用夹持、吸附等方式对工作料带21进行固定。工作料带21被切断后，将由第一定位组件320固定。
而且，放卷机构100及固定机构200能够相对于第一定位组件320沿第一方向往复移动，以使固定机构200(既可以是第一固定组件210，也可以是第二固定组件220)所固定的备用料带22与第一定位组件320所固定的工作料带21对齐。其中，第一方向指的是第一放卷组件110与第二放卷组件120放卷的两条料带相间隔的方向，也即图3所示的上下方向或图2所示的左右方向。
固定机构200沿第一方向往复移动的过程中途经第一位置及第二位置。如图3所示，第二放卷组件120放卷输出的料带作为工作料带21时，固定机构200位于第一位置，第二固定组件220与第一定位组件320对齐，第二放卷组件120放卷输出的工作料带21依次途经第二固定组件220、第一裁切组件310及第一定位组件320，直至向下游输送至裁切工位进行切片。
此时，第一放卷组件110上的料带为备用料带22。当第二放卷组件120上的料带即将放卷完时，第二固定组件220及第一定位组件320将同时固定工作料带21，第一裁切组件310将固定的工作料带21切断，从而得到固定于第一定位组件320的工作料带21。接着，放卷机构100及固定机构200沿第一方向(图3所示上方)移动至第二位置，以使第一固定组件210与第一定位组件320对齐。此时，第一放卷组件110放卷的备用料带22与第一定位组件320所固定的工作料带21对齐。贴胶机构400在对齐的备用料带22及工作料带21的至少一侧(通常为两侧)贴上胶片30(如图10所示)，胶片30的其中一部分与备用料带22的起始端粘接，另一部分与工作料带21的切断端粘接，便可将第一放卷组件110放卷的备用料带22与原先的工作料带21连接并形成新的工作料带21。然后，第一固定组件210及第一定位组件320分别释放所固定的料带，第一放卷组件110便可向下游放卷输出工作料带21。在第一放卷组件110放卷输出工作料带21的过程中，第二放卷组件120上则可装载新的料卷以作为备用料带22。
请一并参阅图4，具体在本实施例中，接带机构300还包括第一驱动件330，第一驱动件330与第一裁切组件310传动连接，并能够驱动第一裁切组件310靠近或远离第一定位组件320与固定机构200之间的料带。
为保证换卷装置10的工作过程更有序，第一驱动件330带动第一裁切组件310移动的方向与固定机构200的移动方向一致，均为第一方向。当第一裁切组 件310将固定机构200及第一定位组件320共同固定的工作料带21切断后，可在第一驱动件330的驱动下远离工作料带21，从而暴露出工作料带21的切断端，并对贴胶机构400的贴胶轨迹形成避让，以防止因第一裁切组件310的遮挡而导致贴胶机构400无法顺利在备用料带22及工作料带21上贴胶片30。
需要指出的是，在正常工作状态下，第一定位组件320与固定机构200之间的料带为工作料带21；而在换卷过程中，第一定位组件320与固定机构200之间的料带既包括工作料带21，也包括备用料带22。
同样的，当第一放卷组件110上的料带作为工作料带21即将放卷完时，第一固定组件210及第一定位组件320同时固定当前的工作料带21，再由第一裁切组件310将被固定的工作料带21切断。接着，放卷机构100及固定机构200相对于第一定位组件320沿第一方向(图3所示下方)移动至第一位置，以使第二固定组件220与第一定位组件320对齐。此时，第二放卷组件120放卷输出的备用料带22与第一定位组件320所固定的工作料带21对齐。由贴胶机构400在对齐的备用料带22及工作料带21的至少一侧贴上胶片30，便可将第二放卷组件120放卷的备用料带22与原先的工作料带21连接并形成新的工作料带21。然后，第二固定组件220及第一定位组件320分别释放所固定的料带，第二放卷组件120便可向下游放卷输出工作料带21。而第二放卷组件120放卷输出工作料带21的过程中，第一放卷组件110上又可装载新的料卷以作为备用料带22。
依此类推，第一放卷组件110及第二放卷组件120将交替进行工作料带21的放卷，并在工作料带21放卷完后实现料带的自动换卷。而在换卷过程中，第一定位组件320始终对原先的工作料带21保持固定，而固定机构200则对备用料带22保持固定，从而能够保证工作料带21与备用料带22可靠地对齐。
在本实施例中，固定机构200与放卷机构100固定连接，以使第一放卷组件110及第二放卷组件120能够随固定机构200沿第一方向同步移动。如此，第一放卷组件110及第二放卷组件120与第一固定组件210及第二固定组件220的相对位置可保持不变。在换卷过程中，放卷机构100及固定机构200沿第一方向往复移动时，同步性更好。
请再次参阅图1及图2，具体在本实施例中，换卷装置10还包括底板600及传动机构700。而且，放卷机构100还包括移动板130，移动板130沿第一方向可滑动地安装于底板600，第一放卷组件110、第二放卷组件120及固定机构200均安装于移动板130上。
传动机构700可采用气缸、电缸或电机(与配套的螺纹丝杠副配合使用)等结构，传动机构700能够驱动移动板130沿第一方向滑动，以带动固定机构200在第一位置与第二位置之间移动。可见，传动机构700驱动固定机构200沿第一方向移动时，第一放卷组件110及第二放卷组件120也将随移动板130沿第一方向同步移动。
底板600能够用于与其他设备，如卷绕机的大板固定连接，接带机构300也可安装于底板600。具体在本实施例中，放卷机构100还包括竖板140，竖板140安装于移动板130并沿垂直于底板600表面的方向延伸，第一放卷组件110及第二放卷组件120均设置于竖板140。可见，放卷机构100能够合理利用底板600上方的空间，从而使得换卷装置100的结构更紧凑。
此外，放卷机构100设于底板600沿第二方向上的一端，第二方向垂直于第一方向，指的是图1所示的左右方向。接带机构300与放卷机构100在第二方向上间隔设置，而贴胶结构400与接带机构300在第一方向上间隔设置。因此，底板600上方的空间可得到充分利用，从而使得换卷装置100的结构更紧 凑。
请再次参阅图3，在本实施例中，接带机构300还包括第二定位组件340及第二裁切组件350，第二定位组件340位于第一定位组件320在第一方向上的一侧并与第一定位组件320间隔设置，第二裁切组件350设置于第二定位组件340的上游(图2所示左侧)。
固定机构200途经第一位置时，除了第二固定组件220与第一定位组件320对齐，第一固定组件210也将与第二定位组件340对齐。此时，由第一放卷组件110放卷的备用料带22依次途经第二裁切组件350及第二定位组件340，且第二裁切组件350能够切断由第一固定组件210及第二定位组件340共同固定的备用料带22。
可见，在进行换卷之前，第一放卷组件110放卷的备用料带22也将被切断，从而形成固定于第一固定组件210的备用料带22。如此，将有利于精确控制备用料带22伸出于第一固定组件210的长度。在固定机构200移动至第二位置以准备换卷，且第一固定组件210与第一定位组件320对齐时，第一固定组件210所固定的备用料带22能够更好的与第一定位组件320固定的工作料带21相匹配，即备用料带22的起始端与工作料带21的切断端共面，从而便于贴胶机构400顺利贴合胶片30。
进一步的，接带机构300还包括第三定位组件360及第三裁切组件370。而且，第三定位组件360位于第一定位组件320背向第二定位组件340的一侧并与第一定位组件320间隔设置，第三裁切组件370设置于第三定位组件360的上游。也就是说，第三定位组件360及第二定位组件340分别位于第一定位组件320在第一方向上的两侧，即图3所示的上下两侧。
固定机构200途经第二位置时，除了第一固定组件210与第一定位组件320 对齐，第二固定组件220也将与第三定位组件360对齐。此时，由第二放卷组件120放卷的备用料带22依次途经第三裁切组件370及第三定位组件360，且第三裁切组件370能够切断由第二固定组件220及第三定位组件360共同固定的备用料带22。
同样的，在进行换卷之前，第二放卷组件120放卷的备用料带22也将被切断，从而形成固定于第二固定组件220的备用料带22。如此，备用料带22伸出于第二固定组件220的长度，与备用料带22伸出于第一固定组件210的长度能够保持较好的一致性。在固定机构200移动至第一位置以准备换卷，且第二固定组件220与第一定位组件320对齐时，第二固定组件220所固定的备用料带22能够更好的与第一定位组件320固定的工作料带21相匹配，从而便于贴胶机构400贴合胶片30。
请一并参阅图5，在本实施例中，第二裁切组件350包括上刀351、下刀352及裁切驱动件353，第一放卷组件110放卷输出的备用料带22途经第二裁切组件350时由下刀352支撑，且下刀352位于上刀351背向第二定位组件340的一侧。
具体的，上刀351与下刀352相对设置，牵引至第二定位组件350的备用料带22从上刀351与下刀352之间穿过。上刀351可通过连接座354与裁切驱动件353的驱动端连接，裁切驱动件353一般为气缸，通过带动上刀351相对于下刀352移动而将支撑于下刀352备用料带22切断。
而且，由于下刀352位于上刀351背向第二定位组件340的一侧，即下刀352位于上刀351的上游侧，即图3所示的右侧。因此，当备用料带22被切断后，下刀352的支撑面(上表面)能够对备用料带22的起始端进行支撑，从而避免备用料带22的起始端发生翘起。
进一步的，在本实施例中，第二定位组件340包括支撑板341、压杆342及弹性件343，压杆342能够在弹性件343的作用下将备用料带22压持于支撑板341的支撑面。而且，下刀352固定连接于支撑板341，且下刀352的支撑面与支撑板341的支撑面平齐。
在第一固定组件210与第二定位组件340对齐时，可通过人工牵引将第一放卷组件110放卷的备用料带22引入第二定位组件340并固定，从而使得第一固定组件210及第二定位组件340能够共同固定备用料带22。支撑板341能够对备用料带22进行支撑。在对备用料带22进行牵引时，可先手动抬起压杆342以使压杆342远离支撑板341，待备用料带22由压杆342下方穿过后再释放压杆342，压杆342便能够在弹性件343的作用下与支撑板341的支撑面抵持，以实现对备用料带22的压持。
由于下刀352能够固定安装于支撑板341，即第二裁切组件350与第二定位组件340能够共用支撑板341，故能够在一定程度上简化接带机构300的结构，从而使得换卷装置10的结构更紧凑。在将备用料带22切断时，支撑板341的支撑面及下刀352的支撑面能够共同支撑备用料带22且保持不动，故能够防止备用料带22在切断后起始端发生翘起。
具体的，支撑板341的边缘设置有弯座3412，弯座3412的一端延伸至支撑板341支撑面的上方，压杆342可滑动地穿设于弯座3412。弹性件343为压缩弹簧，压缩弹簧套设于压杆342且两端分别与弯座3412及压杆342的头部(朝向支撑板341表面的一端)抵接，从而为压杆342提供向下的作用力。此外，为了方便人工抬起压杆342，压杆342远离支撑板341支撑面的一端还设置有手柄3421。
更进一步的，具体在本实施例中，支撑板341的表面形成有供备用料带22 通过的导向槽3411。导向槽3411能够对备用料带22进行导向及限位，从而方便对备用料带22实现准确的牵引。具体的，支撑板341上设置两个相对设置的导向块(图未标)，从而形成导向槽3411。显然，在其他实施例中，导向槽3411也可与支撑板341一体成型。
需要指出的是，第三定位组件360及第三裁切组件370的结构及功能与第二定位组件340及第二裁切组件350的结构及功能大致相同，故在此不再赘述。
请一并参阅图6至图8，贴胶机构400可安装于底板600，贴胶机构400包括贴胶驱动件410、吸板420及摆动组件430。其中，两个吸板420安装于贴胶驱动件410的驱动端，并能够在贴胶驱动件410的驱动下合拢或展平。
贴胶驱动件410可采用夹爪气缸，两个吸板420则分别安装于夹爪气缸的两个夹爪上。吸板420具有吸附面，吸附面可通过负压、静电吸附等方式对胶片30进行吸附。当两个吸板420在贴胶驱动件410的驱动下展平时，两个吸板420的吸附面相互远离至共面或大致共面的状态；当两个吸板420在贴胶驱动件410的驱动下合拢时，两个吸板420的吸附面相互靠拢，直至相贴合或接近贴合。
进一步的，摆动组件430能够带动贴胶驱动件410在备胶位置与贴胶位置之间摆动。具体的，贴胶驱动件410远离吸板420的一端能够绕转轴转动，从而使贴胶驱动件410实现摆动。贴胶驱动件410的转轴一般垂直于第一方向，可沿图6所示的左右方向延伸。相较于贴胶位置，备胶位置距离固定机构200与第一定位组件320之间的料带较远。在备胶位置，用于连接备用料带22与工作料带21的胶片30可上料至其中至少一个吸板420上。而在贴胶位置，贴胶驱动件410则能够带动吸板420将所吸附的胶片30贴合于相对齐的备用料带22及工作料带21的表面。
具体的，摆动组件430带动贴胶驱动件410摆动至备胶位置时，贴胶驱动 件410可驱动两个吸板420展平。此时，两个吸板420的吸附面朝上且大致处于水平状态，故预先存储或由其他机构实时制备的胶片30便能够顺利被吸板420的吸附面承接并吸附。
待吸板420上的胶片30上料完成后，两个吸板420依然保持展平，摆动组件430带动贴胶驱动件410摆动至贴胶位置。此时，两个吸板420则分别位于相对齐的备用料带22与工作料带21的上侧及下侧。贴胶驱动件410由备胶位置摆动至贴胶位置时，大致需摆动90度，故两个吸板420的吸附面将由水平状态切换至大致呈竖直状态，且其中一个吸板420位于相对齐的备用料带22及工作料带21的上方，而另一个吸板420位于相对齐的备用料带22及工作料带21的下方。
接着，贴胶驱动件410驱使两个吸板420合拢，两个吸板420的吸附面相互靠近，直至将工作料带21的切断端及备用料带22的起始端夹持于两个吸板420之间。此时，吸板420吸附面上的胶片30将便能够与备用料带22的起始端及工作料带21的切断端粘接，从而连接备用料带22与工作料带21。贴胶完成后，两个吸板420将在贴胶驱动件410的驱动下再次展平，并在摆动组件430的带动下回到备胶位置，以准备下一次贴胶。
可见，贴胶机构400能够快速实现自动贴胶，从而使得换卷装置10的换卷效率进一步提升。而且，贴胶机构400在备胶位置与贴胶位置之间进行转移时，只需要绕转轴摆动即可，无需在多个方向设置直线驱动组件，从而能够简化贴胶机构400的结构。
具体在本实施例中，摆动组件430包括支座431、摆座432、摆动驱动件433，摆座432可转动地安装于支座431，贴胶驱动件410固定安装于摆座432，摆动驱动件433能够驱动摆座432转动，以使摆座432带动贴胶驱动件410在备胶 位置与贴胶位置之间摆动。
支座431上形成有U形的安装部(图未标)，摆座432能够通过销轴(图未标)可转动地安装于支座431呈U形的安装部内，从而保证转动过程中的稳定性。摆座432可以为贴胶驱动件410提供较大的安装面积。具体的，摆动组件430还包括连杆434，连杆434的一端与销轴固定连接，另一端与摆动驱动件433的移动端铰接。而且，摆动驱动件433的移动端可受控地伸缩，并通过连杆434带动销轴旋转，从而驱动摆座432转动。摆动驱动件433可以是气缸，其固定端可以铰接于移载组件440的第二滑动板443(见图6及图7)。
请再次参阅图1及图6，在本实施例中，换卷装置10还包括备胶机构500，备胶机构500能够将放卷的胶带裁切成胶片30，并将胶片30输送至位于备胶位置的吸板420的表面。
备胶机构500也可安装于底板600。备胶机构500能够利用胶带实时制备胶片30，从而使得换卷装置10实现备胶、贴胶一体化操作，能够进一步减少人工操作。而且，备胶机构500切好的胶片30能够直接转移至吸板420的表面，故无需对胶片30进行存放，从而能够避免胶片30的表面在存放过程中沾灰。
请一并参阅图9，具体在本实施例中，备胶机构500包括胶带放卷组件510、牵引组件520及切断组件530。
胶带放卷组件510可以包括放卷轴，胶带放卷组件510用于放卷胶带。在胶带放卷组件510的下游，一般还设置有张力调节组件(图未标)及过辊(图未标)，张力调节组件能够维持胶带的张力。牵引组件520用于在吸板420的上方拉取预设长度的胶带，切断组件530用于将牵引组件520与胶带放卷组件510之间的胶带切断，以得到承载于吸板420的胶片30。
可见，切断组件530每次裁切所得到的胶片30均可直接由吸板420承接， 从而加快了胶片30上料的节拍并能够避免胶片30被污染。
此外，备胶机构500还包括起支撑作用的支撑座540，胶带放卷组件510、牵引组件520及切断组件530均安装于支撑座540上。支撑座540可沿底座600的表面垂直延伸，从而能够合理利用底座600上方的空间，使得换卷装置10的结构更加紧凑。
进一步的，备胶机构500还包括下压组件560，下压组件560能够固定牵引组件520与胶带放卷组件510之间的胶带并带动所固定的胶带朝吸板420(即图6所示的下方)移动，直至位于吸板420的上方的胶带被吸板420吸附。也就是说，胶片30在从胶带上切下之前便由吸板420进行吸附，故切断组件530将胶带切断后所得到的胶片30将直接固定于吸板420的吸附面，从而省略了片状的胶片30从备胶机构500的输出端向吸板420转移的过程，避免了胶片30在转移过程中发生污染、翘曲或偏转。
具体在本实施例中，支撑座540上沿竖直方向滑动连接有连接板550，切断组件530及下压组件560均安装于连接板550。此外，下压组件560包括压紧气缸561、第一夹爪562及第二夹爪563，第一夹爪562固定于压紧气缸561的移动端，第二夹爪563设于第一夹爪562的下方并与连接板550固定连接。
进一步的，支撑座540的背向连接板550的一侧沿竖直方向滑动连接有第二连接座570，第二连接座570与连接板550之间通过连接块(图未标)固连。支撑座540上设置有第一气缸581，第一气缸581的移动端固连第二连接座570。第二连接座570沿水平方向滑动连接有移动座590，第二连接座570上设置有第二气缸582，第二气缸582的移动端固连移动座590。
牵引组件520包括牵引气缸521，牵引气缸521固设于移动座590上。牵引气缸521的两移动端分别固连第三夹爪522及第四夹爪523。进行胶带拉取时， 第三夹爪522及第四夹爪523夹取胶带并在第二气缸582的驱动下随移动座590水平移动，以拉取预设长度的胶带。然后，第一夹爪562在压紧气缸561的带动下与第二夹爪563配合夹紧胶带，第一气缸581驱动连接板550下降，从而驱使下压组件560带动所夹紧的胶带下移，直至牵引组件520所拉取的胶带被吸板420的吸附面吸附。最后，切断组件530切断胶带，得到吸附于吸板420的胶片30。
请再次参阅图6及图7，在本实施例中，贴胶机构400还包括移载组件440，在贴胶驱动件410位于备胶位置时，移载组件440能够驱动贴胶驱动件410沿第一方向移动，以使两个吸板420依次途经能够承接备胶机构500输出的胶片30的位置。
由于两个吸板420之间的距离较大，而备胶机构500输出胶片30的位置一般是固定的，故无法将胶片30同时输送至两个吸板420的表面。具体在本实施例中，能够承接备胶机构500输出的胶片30的位置指的是备胶机构500输出端的方向。设置移载组件440后，可先由其中一个吸板420承接备胶机构500输出的胶片30，接着，移载组件440驱动贴胶驱动件410沿第一方向移动一定距离(一般为两个吸板420之间的间距)，以使另一个吸板420也进入能够承接备胶机构500输出的胶片30的位置，则另一个吸板420便可承接备胶机构500输出的胶片30。
可以理解，备胶位置包括两个位置，即第一备胶子位置及第二备胶子位置。以图7所示为例，进入备胶位置的贴胶驱动件410位于第一备胶子位置，故先由上方的吸板420承接备胶机构500输出的胶片30；接着，移载组件440可带动贴胶驱动件410向上移动一定距离，以使贴胶驱动件410移动至第二备胶子位置，故下方的吸板420也能承接备胶机构500输出的胶片30。
需要指出的是，在其他实施例中，也可省略移载组件440而使备胶机构500的输出端沿第一方向移动，从而将裁切得到的胶片30依次上料至两个吸板420的吸附面。
进一步的，在本实施例中，在贴胶驱动件410位于贴胶位置时，移载组件440还能够驱动贴胶驱动件410沿第一方向移动，以使两个吸板420合拢时能够夹持相对齐的备用料带22及工作料带21。
为了避免摆动组件430带动贴胶驱动件410向贴胶位置摆动的过程中，贴胶驱动件410及其上的吸板420与第一定位组件320与固定机构200之间的料带发生干涉，故贴胶驱动件410由备胶位置向贴胶位置摆动之前，其与待粘接的料带(第一定位组件320固定的工作料带21及固定机构200固定的备用料带22)之间预留有较大的空间。因此，在摆动组件430带动贴胶驱动件410摆动至贴胶位置后，吸板420与待粘接的料带之间可能因距离过大而无法顺利完成贴胶。此时，移载组件440便可带动贴胶驱动件410靠近待粘接的料带，以保证贴胶机构400顺利完成贴胶。
此外，在本实施例中，移载组件440包括第一移载结构(图未标)及第二移载结构(图未标)，第一移载结构能够驱动贴胶驱动件410沿第一方向移动，以使两个吸板410依次途经能够承接备胶机构500输出的胶片30的位置；第二移载结构能够驱动贴胶驱动件410沿第一方向朝向第一定位组件320与固定机构200之间的料带移动，以使两个吸板420合拢时能够夹持第一定位组件320与固定机构200之间的料带。
也就是说，在贴胶驱动件410位于备胶位置时，能够在第一移载结构的驱动下沿第一方向移动，而贴胶驱动件410位于贴胶位置时，则能够在第二移载结构的驱动下沿第一方向移动。因此，贴胶驱动件410在不同的位置时将由不 同的移载结构进行驱动，故控制更方便。
进一步的，具体在本实施例中，第一移载结构包括第一滑动板441及第一移载气缸442，第二述移载结构第二滑动板443及第二移载气缸444。
第一滑动板441能够在第一移载气缸442的驱动下沿第一方向滑动。具体的，第一滑动板441可通过导轨-滑块沿第一方向可滑动地安装于底板600上，第一移载气缸442设于底板600。第二滑动板443沿第一方向可滑动地安装于第一滑动板441，第二移载气缸444安装于第一滑动板441并能够驱动第二滑动板443沿第一方向滑动。贴胶驱动件410安装于第二滑动板443，具体的，贴胶机构400的支座431安装于第二滑动板443，从而使得贴胶驱动件410及摆动组件430整体能够随第二滑动板443沿第一方向移动。
其中，第一移载气缸442能够驱动第一滑动板441沿第一方向滑动，以带动两个吸板420依次途经能够承接备胶机构500输出的胶片30的位置；第二移载气缸444能够驱动第二滑动板443沿第一方向滑动，以使贴胶驱动件410在贴胶位置朝向第一定位组件320与固定机构200之间的料带移动。
具体的，第一移载气缸442及第二移载气缸444一般具有不同的行程。第一移载气缸442的行程一般等于两个吸板420之间的距离，通过第一移载气缸442往复动作，便可带动两个吸板420依次途经能够承接备胶机构500输出的片料的位置。可见，确定第一移载气缸442及第二移载气缸444合适的行程后，第一移载气缸442及第二移载气缸444按照一定的规律进行往复移动即可使得备胶及贴胶过程顺利进行，控制更方便。
需要指出的是，在其他实施例中，移载组件440也可采用其他结构。譬如，移载组件440采用电机及与电机配套的螺纹丝杠副结构，将电机的旋转运动转化成贴胶驱动件410在第一方向上的直线运动。通过控制电机主轴的旋转圈数， 也可实现带动两个吸板420依次途经能够承接备胶机构500输出的片料的位置，并使贴胶驱动件410在贴胶位置朝向第一定位组件320与固定机构200之间的料带移动。
上述换卷装置10，第一放卷组件110及第二放卷组件120能够放卷输出工作料带21及备用料带22，当第一放卷组件110的工作料带21即将放卷完毕时，第一裁切组件310切断由固定机构200及第一定位组件320共同固定的工作料带21，通过使固定机构200相对于第一定位组件320沿第一方向移动，可将第二放卷组件120放卷的备用料带22与第一定位组件320所固定的工作料带21对齐。接着，摆动组件430带动贴胶驱动件410由备胶位置摆动至贴胶位置，贴胶机构400带动两个吸板420合拢便可将胶片30贴合于相对齐的备用料带22及工作料带21，从而将备用料带22与工作料带21连接并形成新的工作料带21，而第一放卷组件110上则可装载新的料卷以作为备用料带22。依此类推，上述换卷装置10可实现料带的自动换卷，换卷效率较高。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
