请参阅图1,本申请一实施例提供的一种换卷装置,包括放卷机构10、第一固定机构14、第二固定机构30、裁切机构20及接带机构32。
放卷机构10包括滑动支架11以及安装于滑动支架11上的放卷组件(图未标)。滑动支架11被构造为可受控地沿第一方向移动。放卷组件用于输出工作料带与备用料带。也就是说,放卷组件可输出两条料带,该两条料带其中一条为工作料带时,其中另一条则为备用料带。第一固定机构14设置于滑动支架11,以随滑动支架11一同沿第一方向移动。第一固定机构14位于放卷组件的下游,能够受控地固定放卷组件输出的工作料带和备用料带。第二固定机构30布置于第一固定机构14的下游,以在第一固定机构14和第二固定机构 30之间形成接带工位c。第二固定机构30能够受控地固定穿出第一固定机构14的工作料带和备用料带。其中,位于第一固定机构14和第二固定机构30之间(即接带工位c)的工作料带和备用料带沿第一方向间隔布设。裁切机构20对应于所述接带工位c布设,用于切断位于接带工位c的工作料带和备用料带。接带机构32对应于接带工位c布设。优选地,裁切组件20设置于滑动支架11上,以随滑动支架11一同沿第一方向移动。
其中,第一固定机构14能够跟随滑动支架11沿第一方向移动至由第一固定机构14固定的备用料带与由第二固定机构30固定的工作料带在接带工位c对齐,并允许接带机构32连接在接带工位c对齐的工作料带和备用料带。
上述换卷装置,在实际作业时,放卷组件放卷输出的工作料带依次穿过第一固定机构14、接带工位c及第二固定机构30,并向下游输送。放卷组件放卷输出的备用料带的起头端依次穿过第一固定机构14及接带工位c,并固定于第二固定机构30。
当放卷组件上的工作料带的料卷用完而需要换卷时,首先,第一固定机构14将放卷组件放卷输出的工作料带和备用料带同时固定,第二固定机构30也固定工作料带(此时,工作料带被第一固定机构14和第二固定机构30共同固定,备用料带也被第一固定机构14和第二固定机构30共同固定)。然后,裁切机构20在接带工位c将工作料带和备用料带切断。再然后,滑动支架11带动第一固定机构14沿第一方向移动至固定于第一固定机构14的备用料带的切断端与固定于第二固定机构30的工作料带的切断端在接带工位c对齐。再然后,接带机构32将在接带工位c对齐的工作料带的切断端和备用料带的切断端相连接。最后,第一固定机构14解除对备用料带的固定,第二固定机构30也解除对工作料带的固定,以便于放卷组件放卷输出的备用料带依次通过第一固定机构14、接带工位c和第二固定机构30并向下游输送,即此时由放卷组件放卷输出的备用料带转换成为了工作料带。并且,此时可对放卷组件上用完的料卷进行更换,并将更换的新料卷输出的料带作为备用料带,且牵引该备用料带的起头端依次穿出第一固定机构14和接带工位c,并固定于第二固定机构30,为下一次的换卷作准备。
如此,本申请的换卷装置可实现工作料带和备用料带的自动切换(即自动 换卷),与现有技术中采用的人工换卷方式相比,大大缩短了停机时长,提高了生产效率,且无需人员值守,降低了人工成本。
需要说明的是,工作料带指的是由放卷组件放卷输出,并依次穿过第一固定机构14、接带工位c和第二固定机构30,并向下游输送的料带。备用料带指的是由放卷组件放卷输出,且其起头端依次穿过第一固定机构14和接带工位c,并固定于第二固定机构30而不向下游输送的料带。可以理解的是,经过自动换卷后,备用料带切换为工作料带而向下游输送,更换的新料卷放卷出的料带作为备用料带。
还需要说明的是,放卷组件放卷输出的工作料带和备用料带可以是极耳料带。当然,在其它一些实施例中,也可以是其它类型的料带,在此不作限定。
还需要说明的是,在一个实施例中,裁切机构20用于沿与第一方向平行的裁切线切断位于接带工位c的工作料带和备用料带,使得被第一固定机构14固定的备用料带的切断端与被第二固定机构30固定的工作料带的切断端在第一方向上是平齐的,避免造成在接带处工作料带的切断端和备用料带的切断端重叠。当然,也可采用沿其它形式的裁切线切断位于接带工位c的工作料带和备用料带,只要能够确保在接带处工作料带的切断端和备用料带的切断端不重叠即可,在此不作限定。
具体到实施例中,放卷机构10还包括底座15及切换驱动件16,滑动支架11沿第一方向可移动地连接于底座15。切换驱动件16安装于底座15,并与滑动支架11传动连接,以驱动滑动支架11沿第一方向相对底座15移动,从而带动第一固定机构14和裁切机构20一同沿第一方向移动,进而使得裁切机构20相对第一固定机构14固定,确保始终能够在接带工位c切断工作料带和备用料带,并且使得第一固定机构14能够带动切断后的备用料带移动至与由第二固定机构30固定的工作料带对齐,以便于接带机构32进行接带,进而实现工作料带和备用料带的切换。可选地,切换驱动件16可以是气缸。
进一步地,底座15上安装有切换滑轨151,滑动支架11上安装有切换滑块111,该切换滑块111与切换滑轨151滑动配合,从而利用切换滑块111相对切换滑轨151的滑动,来实现滑动支架11相对底座15沿第一方向可移动,且使得滑动支架11的移动更加稳定可靠。当然,在另一些实施例中,切换滑 块111也可安装在底座15上,而切换滑轨151安装在滑动支架11上,只要能够实现滑动支架11能够相对底座15沿第一方向可移动即可,在此不作限定。
本申请的实施例中,放卷组件包括第一放卷组件12和第二放卷组件,第一放卷组件12和第二放卷组件分别设置在滑动支架11在第一方向上的两侧。第一放卷组件12用于向第一固定机构14放卷输出可作为工作料带或备用料带的料带a。第二放卷组件用于向第二固定机构14放卷输出可作为工作料带或备用料带的料带b。也就是说,当第一放卷组件12放卷输出的料带a为工作料带时,第二放卷组件放卷输出的料带b即为备用料带;当第一放卷组件12放卷输出的料带a为备用料带时,第二放卷组件放卷输出的料带b即为工作料带。
具体到实施例中,第一放卷组件12包括第一料轴121及第一放卷驱动件122,第一料轴121绕自身轴线可转动地连接于滑动支架11。第一放卷驱动件122安装于滑动支架11,且与第一料轴121传动连接,以驱动第一料轴121绕自身轴线转动,从而带动安装在第一料轴121上的料卷转动放卷。
第二放卷组件包括第二料轴及第二放卷驱动件,第二料轴绕自身轴线可转动地连接于滑动支架11。第二放卷驱动件安装于滑动支架11,且与第二料轴传动连接,以驱动第二料轴绕自身轴线转动,从而带动安装在第二料轴上的料卷转动放卷。
具体到实施例中,放卷机构10还包括安装轴125,该安装轴125固定安装在滑动支架11上,第一料轴121和第二料轴分别通过轴承套装于安装轴125的两端,使得第一料轴121和第二料轴能够相对安装轴125转动。
具体到实施例中,第一放卷驱动件122可通过带传动结构与第一料轴121实现传动连接。具体地,第一放卷驱动件122的输出轴上安装第一主动轮123,第一料轴121上安装第一从动轮,第一主动轮123和第一从动轮之间套设有第一传动带124,从而使得第一放卷驱动件122驱动第一主动轮123转动,第一主动轮123通过第一传动带124带动第一从动轮转动,第一从动轮再带动第一料轴121转动,进而实现安装在第一料轴121上的料卷转动放卷料带a。可选地,第一放卷驱动件122可以是电机。
当然,在其它实施例中,第一放卷驱动件122也可通过其它传动结构来实 现与第一料轴121的传动连接,例如链传动结构、齿轮传动结构等,在此不作限定。
具体到实施例中,第二放卷驱动件可通过带传动结构与第二料轴实现传动连接。具体地,第二放卷驱动件的输出轴上安装第二主动轮,第二料轴上安装第二从动轮,第二主动轮和第二从动轮之间套设有第二传动带,从而使得第二放卷驱动件驱动第二主动轮转动,第二主动轮通过第二传动带带动第二从动轮转动,第二从动轮再带动第二料轴转动,进而实现安装在第二料轴上的料卷放卷输出料带。可选地,第二放卷驱动件可以是电机。
当然,在其它实施例中,第二放卷驱动件也可通过其它传动结构来实现与第二料轴的传动连接,例如链传动结构、齿轮传动结构等,在此不作限定。
本申请的实施例中,第一固定机构14与第二固定机构30分别位于接带工位c在与第一方向垂直的第三方向上的两侧,裁切机构20与接带机构32分别位于接带工位c在第二方向上的两侧,该第二方向垂直于第一方向和第三方向,从而使得第一固定机构14、第二固定机构30、裁切机构20及接带机构32更加紧凑的围绕接带工位c布设,结构紧凑,有利于提高空间利用率。
具体到图1所示的实施例中,第一方向为垂直于纸面的方向,第二方向为左右方向,第三方向为上下方向。第一固定机构14位于接带工位c的上方,第二固定机构30位于接带工位c的下方,裁切机构20位于接带工位c的左侧,接带机构32位于接带工位c的右侧。
请参见图1及图2所示,本申请的实施例中,第一固定机构14具有沿第一方向间隔布设的第一固定位144和第二固定位145。第一固定位144和第二固定位145用于固定工作料带和备用料带。如此,放卷组件放卷输出的其中一条料带穿过第一固定位144进入接带工位c,其中另一条料带穿过第二固定位145进入接带工位c,并且当需要换卷时,第一固定机构14分别将两条料带(即工作料带和备用料带)同时固定于第一固定位144和第二固定位145,以实现工作料带和备用料带的同时固定。
具体到实施例中,第一固定机构14包括安装于滑动支架11的夹紧驱动件142以及与该夹紧驱动件142驱动连接的两个夹块143,该两个夹块143之间形成上述第一固定位144和第二固定位145。夹紧驱动件142用于驱动两个夹 块143相互夹紧或松开。当夹紧驱动件142驱动两个夹块143夹紧时,两个夹块143同时将放卷组件放卷输出的两条料带分别夹紧于第一固定位144和第二固定位145。当夹紧驱动件142驱动两个夹块143松开时,两个夹块143同时解除对放卷组件放卷输出的两条料带的夹持。第一固定机构14能够实现对两条料带的同时夹紧或同时松开,并且结构简单,对两条料带的夹紧稳定可靠。

当两个裁切组件22移动至各自的裁切位置时,接带工位c的工作料带和备用料带分别进入对应的裁切组件22的第一切刀222和第二切刀223之间,进而使得两个裁切组件22的第一切刀222和第二切刀223裁切配合,以分别切断工作料带和备用料带。

如此,当需要切断接带工位c的工作料带和备用料带时,首先,移动组件23驱动调整组件21沿第四方向移动至两个裁切组件22位于接带工位c的工作料带和备用料带之间,使得工作料带和备用料带分别与对应的裁切组件22的第一切刀222和第二切刀223之间的位置在第一方向上对齐。然后,调整组件21驱动两个裁切组件22沿第一方向相互远离移动至裁切位置,使得工作料带和备用料带分别进入对应的裁切组件22的第一切刀222和第二切刀223之间。再然后,两个裁切组件22的第一切刀222和第二切刀223裁切配合,分别将工作料带和备用料带切断。最后,调整组件21驱动两个裁切组件22沿第一方向相互靠近移动而复位,移动组件23驱动调整组件21沿第四方向反向移动而复位,从而避免对滑动支架11沿第一方向移动的过程中裁切机构20与其它部件干涉。

进一步地,移动板232上安装有第一滑轨2321,安装座221上安装有第一滑块2211,第一滑块2211与第一滑轨2321滑动配合,从而利用第一滑块2211沿第一滑轨2321的滑动实现安装座221相对移动板232沿第一方向可移动,并确保安装座221沿第一方向的移动平稳可靠。
进一步地,调整组件21包括夹爪气缸211,该夹爪气缸211的两个驱动端分别与两个裁切组件22的安装座221连接,以使夹爪气缸211能够驱动两个裁切组件22的安装座221沿第一方向相互靠近或远离。
具体到实施例中,每一裁切组件22还包括导向杆224及裁切驱动件225,安装座221上开设有导向孔,导向杆224贯穿该导向孔设置,并与该导向孔滑动配合。第一切刀222固定连接于安装座221,第二切刀223固定连接于导向杆224的一端。裁切驱动件225安装于安装座221,且与导向杆224的另一端传动连接,以驱动导向杆224沿导向孔移动,从而带动第二切刀223相对第一切刀222移动,进而切断第二切刀223和第一切刀222之间的料带(工作料带或备用料带)。如此,利用导向杆224和导向孔的滑动配合对第二切刀223的移动进行导向,以确保第二切刀223移动的过程中与第一切刀222裁切配合而将二者之间的料带切断。可选地,裁切驱动件225可以是气缸。第二切刀223通过切刀座226固定连接于导向杆224的一端。
需要说明的是,裁切机构20并不仅限于安装在滑动支架11上,随滑动支架11一同沿第一方向移动。在其它一些实施例中,裁切机构20也可单独设置驱动结构(例如直线模组、电缸等等)来驱动裁切机构20沿第一方向移动(具体地,移动组件21的移动驱动件231安装在该驱动结构上),以调整两个裁切组件22与接带工位c的工作料带和备用料带的位置关系,确保两个裁切组件22在移动组件21和调整组件23的驱动下能够移动至各自的裁切位置进行裁切。
请参见图1、图5及图6所示,本申请的实施例中,第二固定机构30包括第一固定组件33、第二固定组件34及第三固定组件31,该第一固定组件33和第二固定组件34分别位于第三固定组件31在第一方向上的两侧。在滑动支架11沿第一方向移动的过程中,第一固定位144和第二固定位145能够交替地与第三固定组件31对齐。
其中,当第一固定位144与第三固定组件31对齐时,第二固定位145与第二固定组件34对齐,以使第二固定组件34固定连接由第二固定位145穿出的备用料带。此时,由第一固定位144穿出的工作料带继续穿过接带工位c和第三固定组件31,并向下游输送。

如此,利用第一固定组件33或第二固定组件34连接固定备用料带的起头端,以便于裁切组件22同时对接带工位c的工作料带和备用料带进行切断,有利于提高切断效果。可以理解的是,利用裁切机构20的上述两个裁切组件22分别将工作料带和备用料带切断。
具体到实施例中,滑动支架11沿第一方向移动的过程中包括第一位置和第二位置。

需要说明的是,第一固定组件33也可采用其它的结构,例如真空吸附板或夹爪气缸等结构,只要能够固定由第一固定位144穿出的备用料带的起头端即可,在此不作限定。
具体到实施例中,第二固定组件34包括第二支架341、第二固定夹块342、第二活动夹块343,第二固定夹块342固定连接于第二支架341。第二活动夹块343设置于第二支架341,且被构造为可朝向第二固定夹块342靠近或远离。当第二固定位145与第二固定组件34对齐时,由第二固定位145穿出的备用料带穿入第二固定夹块342和第二活动夹块343之间,然后第二活动夹块343朝向第二固定夹块342移动而将二者之间的备用料带夹紧,从而实现对备用料带的夹紧固定,以便于在换卷时裁切机构20对备用料带进行裁切。可选地,第二活动夹块343通过第二旋钮柱塞344安装于第二支架341,从而可通过旋拧该第二旋钮柱塞344来带动第二活动夹块343朝向第二固定夹块342靠近或远离。

请参见图1及图7所示,本申请的实施例中,接带机构32包括贴胶组件,该贴胶组件包括贴胶驱动件323及驱动连接于该贴胶驱动件323的两个贴胶吸盘324,两个贴胶吸盘324中至少一个用于吸附胶带。贴胶驱动件323用于驱动两个贴胶吸盘324处于合拢状态,以将贴胶吸盘324上的胶带粘贴于在接带工位c对齐的工作料带的切断端和备用料带的切断端,从而实现备用料带和工作料带的连接。如此,利用两个贴胶吸盘324的合拢而将胶带粘贴在两个贴胶吸盘324之间的工作料带的切断端和备用料带的切断端,从而实现工作料带和工作料带的连接,贴胶组件结构简单,贴胶动作简单可靠,使得贴胶效率较高且贴胶效果较好。可以理解的是,当只有一个贴胶吸盘324用于吸附胶带时,另一个贴胶吸盘324可以不具备吸附功能(即无需与外部负压源连通,也可不开设与外部气源连通的吸附孔),仅仅起到与用于吸附胶带的贴胶吸盘324配合合拢,以确保将胶带粘贴至工作料带和备用料带的连接处即可。
具体到实施例中,接带机构32还包括平移驱动件321及驱动块322。该平移驱动件321与驱动块322驱动连接。贴胶驱动件323安装于驱动块322上,平移驱动件321用于驱动该驱动块322在备胶位置和贴胶位置之间移动。当驱动块322移动至备胶位置时,贴胶吸盘324吸取胶带。当驱动块322移动至贴胶位置时,贴胶驱动件323驱动两个贴胶吸盘324合拢而处于合拢状态,以将胶带粘贴于工作料带和备用料带。可选地,备胶位置和贴胶位置沿第二方向布设。
如此,当需要接带时,首先,平移驱动件321驱动驱动块322移动至备胶位置,使得贴胶吸盘324吸取胶带。然后,平移驱动件321驱动驱动块322移动至贴胶位置,此时,在接带工位c对齐的工作料带的切断端和备用料带的切断端位于两个贴胶吸盘324之间。再然后,贴胶驱动件323驱动两个贴胶吸盘324合拢而挤压工作料带的切断端和备用料带的切断端,以将贴胶吸盘324 上的胶带粘贴于工作料带的切断端和备用料带的切断端,使得工作料带的切断端和备用料带的切断端通过该胶带相互连接。最后,贴胶驱动件323驱动贴胶吸盘324打开(此时可控制贴胶吸盘324停止对胶带进行吸附,以便于贴胶吸盘324与胶带分离),平移驱动件321驱动驱动块322返回至备胶位置进行备胶,以为下一次的贴胶作准备。可选地,平移驱动件321可以是气缸。
进一步地,接带机构32还包括安装于固定座37上的备胶板325,备胶板325位于备胶位置,且至少一侧表面用于粘贴胶带。
当平移驱动件321驱动驱动块322移动至备胶位置时,备胶板325位于两个贴胶吸盘324之间,此时,贴胶驱动件323驱动两个贴胶吸盘324合拢,使得贴胶吸盘324吸取备胶板325上的胶带,然后贴胶驱动件323驱动两个贴胶吸盘324打开(此时备胶板325上的胶带已被贴胶吸盘324吸取,使得胶带与备胶板325分离)。当备胶板325上的胶带被贴胶吸盘324吸取走后,可利用人工或自动化设备将新的胶带重新粘贴在备胶板325的至少一侧,以供贴胶吸盘324再次吸取。
需要说明的是,为了提高接带效果,两个贴胶吸盘324上均需要吸取胶带,使得在工作料带的切断端和备用料带的切断端的两侧均粘贴胶带,因而在备胶板325的相对两侧均需要粘贴胶带,以便于两个贴胶吸盘324同时吸取胶带。
本申请的实施例中,贴胶驱动件323用于驱动两个贴胶吸盘324彼此反向转动至上述合拢状态和平铺状态。如此,当平移驱动件321驱动驱动块322移动至备胶位置或贴胶位置时,贴胶驱动件323驱动两个贴胶吸盘324彼此反向转动至合拢状态,使得两个贴胶吸盘合拢,进而实现吸取胶带或贴胶。当吸取胶带完成而需要移动至贴胶位置或者贴胶完成而需要移动至备胶位置时,为了避免两个贴胶吸盘324在移动的过程中发生干涉,贴胶驱动件323驱动两个贴胶吸盘324彼此反向转动至平铺状态,确保在移动的过程中两个贴胶吸盘324不会与备胶板325或料带等其它部件造成干涉。可以理解的是,两个贴胶吸盘324由平铺状态向彼此靠拢的方向翻转大致90°即可处于合拢状态,同理,两个贴胶吸盘324由合拢状态向彼此打开的方向翻转大致90°即可处于平铺状态。两个贴胶吸盘324处于平铺状态时,两个贴胶吸盘324处于同一平面内,确保避位效果。可选地,贴胶驱动件323可以是夹爪气缸。
需要说明的是,两个贴胶吸盘324并不仅限于采用彼此反向转动的方式合拢或打开而实现吸取胶带和贴胶。在其它实施例中,还可利用两个贴胶吸盘324平移的方式合拢或打开而实现吸取胶带和贴胶,在此不作限定。当然,当采用两个贴胶吸盘324平移的方式合拢或打开时,还需要额外增设避让驱动气缸,两个贴胶吸盘324吸取胶带或贴胶完成后,需要利用该避让驱动气缸驱动两个贴胶吸盘324移动(例如沿第一方向移动)使得备胶板325或者备用料带和工作料带退出两个贴胶吸盘324之间,而达到避让的效果。需要说明的是,至于驱动两个贴胶吸盘324平移以及利用避让驱动气缸驱动两个贴胶吸盘324避让可采用较为成熟的现有技术,在此不作赘述。
本申请的实施例中,接带机构32还包括接带座326,平移驱动件321固定安装在该接带座326上,备胶板325通过备胶支架327固定连接于该接带座326上。如此,将接带机构32集成安装在接带座326上,有利于提高空间利用率,且拆装方便。
具体到实施例中,换卷装置还包括固定座37(见图1)及底板50(见图1),接带座326和固定架35均固定安装在该固定座37上,底座15和固定座37均固定安装在底板50上,从而实现换卷装置的放卷机构10、第一固定机构14、第二固定机构30、裁切机构20及接带机构32集成布置在底板50上,使得换卷装置能够很好的融入极耳焊接装置,有利于提高设备整体的空间利用率。
下面以第一放卷组件12放卷输出的料带a作为工作料带,第二放卷组件放卷输出的料带b作为备用料带(即滑动支架11位于第二位置)的情况为例,对换卷过程进行说明:
初始时,滑动支架11位于第二位置,第一放卷组件12放卷输出的工作料带由两个夹块143之间的第一固定位144穿入接带工位c,进而穿过第三固定组件31的两个夹持块313之间,并继续向下游输送。第二放卷组件放卷输出的备用料带的起头端由两个夹块143之间的第二固定位145穿入接带工位c,并夹紧固定于第二固定组件34的第二活动夹块343和第二固定夹块342之间。
当第一放卷组件12上的料卷用完而需要换卷时,首先,第一固定机构14的两个夹块143夹紧由第一放卷组件12放卷输出的工作料带和第二放卷组件放卷输出的备用料带(即工作料带夹紧固定于第一固定位144,备用料带夹紧 固定于第二固定位145)。并且,第三固定组件31的两个夹持块313也夹紧固定工作料带。裁切机构20将第一固定位144与第三固定组件31之间的工作料带以及第二固定位145与第二固定组件34之间的备用料带切断。
然后,滑动支架11沿第一方向移动至第一位置,使得第二固定位145与第三固定组件31对齐,从而被夹紧于第二固定位145的备用料带的切断端与被夹紧于第三固定组件31的两个夹持块313之间的工作料带的切断端对齐。接带机构32的平移驱动件321驱动驱动块322移动至贴胶位置,贴胶驱动件323驱动两个贴胶吸盘324处于合拢状态,以在接带工位c将被夹紧固定于第二固定位145的备用料带的切断端与被夹紧固定于第三固定组件31的两个夹持块313之间的工作料带的切断端通过胶带连接,即实现接带。
最后,第一固定机构14的两个夹块143松开对第一放卷组件12放卷输出的工作料带和第二放卷组件放卷输出的备用料带的夹持,第三固定组件31的两个夹持块313也松开对工作料带的夹持,使得第二放卷组件放卷输出的备用料带依次通过第二固定位145、接带工位c及第三固定组件31的两个夹持块313之间,并作为工作料带向下游输送,即完成换卷。
此时,可对第一放卷组件12上用完的料卷进行更换,更换后的新料卷放出的料带作为备用料带,该备用料带的起头端穿过第一固定位144,并夹紧固定于第一固定组件33,以为下一次的换卷作准备。
需要说明的是,第一放卷组件12放卷输出的料带a作为备用料带,第二放卷组件放卷输出的料带b作为工作料带的情况下的换卷过程与上述换卷过程相似,故在此不作赘述。
基于上述换卷装置,本申请还提供一种极耳焊接设备,用于将工作料带切断形成极耳,并将该极耳焊接于极片上。该极耳焊接设备包括如上任一实施例中所述的换卷装置,用于向下游输送工作料带。可以理解的是,该工作料带为极耳料带。
具体地,极耳焊接设备还包括焊接装置,该焊接装置布设于换卷装置的下游,用于切断换卷装置输送的工作料带以形成极耳,并将极耳焊接至极片。
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。
