锂电池在生产过程中需要对电芯包绝缘膜，但是现有技术中，没有限制电芯的推块的位移，容易造成电芯推不到位或推多撞伤电芯，导致撞伤电芯引起安全事故。
因此，本申请实施例提供一种技术方案，请参阅图1与图2，本实施例涉及一种用于电芯包绝缘膜的设备，包括顶推机构1、定位机构2、折边机构3以及动力单元4，顶推机构1包括用于放置电芯5的基座11以及设置在基座11上的顶推组件12，顶推组件12包括顶推块121，顶推组件12还包括用于限制顶推块121位置的第一限位部122；定位机构2设置在基座11的一侧，定位机构2用于对基座11上的电芯5进行定位；折边机构3相对顶推机构1设置，折边机构3用于对包裹在电芯5上的绝缘膜进行折边；动力单元4用于驱动折边机构3对包裹在电芯5上的绝缘膜进行折边以及顶推块121对基座11上的电芯5进行顶推。
值得一提的是，本实施例中，并不限制第一限位部122的具体结构，只要可以限制顶推块121的位置，例如，第一限位部122为限位挡块、限位凹槽、限位孔等，均在本实施例的保护范围内。
区别于现有技术，本实施例中通过顶推块121以及用于限制顶推块121位置的第一限位部122，定位机构2对电芯5进行定位，折边机构3对包裹在电芯5上的绝缘膜进行折边，动力单元4驱动顶推块121对基座11上的电芯5进行顶推，顶推块121的移动位置被第一限位部122限位；顶推块121不会出现行程不到位或超行程的状况，而造成电池推不到位或撞伤电芯5，有效减少电芯5撞伤引起的安全事故。
在一些实施例中，第一限位部122为设置在顶推块121上的限位凹槽。顶推块121位移被限位凹槽限制，限位凹槽的形状、位置决定了顶推块121的移动位置、移动范围，通过实际情况计算所要顶推电芯5的距离，根据距离计算得出限位凹槽的形状范围，就可以保证顶推块121的移动位置，不会出现行程不到位或超行程的状况。
如此，通过设置在顶推块121上的限位凹槽，可以限制顶推块121的移动位置，顶推块121的移动位置不超过限位凹槽的形状范围。
在一些实施例中，请参阅图3与图4，顶推组件12还包括滑块固定板123、第一滑块 124以及凸轮部件125，滑块固定板123上设置有第一滑轨1231，第一滑块124与第一滑轨1231相配合，并可沿第一滑轨1231的延伸方向相对滑动，顶推块121固定在第一滑块124上；凸轮部件125包括与限位凹槽相配合的凸轮1251，凸轮1251可沿限位凹槽的延伸方向相对滑动，凸轮1251与限位凹槽相互配合，以限制顶推块121的位置。凸轮1251通过凸轮安装板1252设置在基座11上，凸轮安装板1252用于对凸轮1251进行固定。
本实施例中，通过第一滑块124与第一滑轨1231的配合，用于限制顶推块121在其他方向上的位移，通过限位凹槽用于限制顶推块121在沿竖直方向(如图中箭头z所指方向)移动的同时，使顶推块121可以向沿第一滑轨1231的延伸方向(如图中箭头y所指方向)进行移动，从而实现顶推块121的顶推功能，顶推块121的顶推的位置被限位凹槽的形状范围所限制，顶推块121顶推的位置是固定的。
如此，顶推块121通过第一滑块124与第一滑轨1231的配合设置在滑块固定板123上，可以实现顶推块121对电芯5的顶推，而通过凸轮1251与限位凹槽的配合，使凸轮1251在限位凹槽内滑动，从而限制顶推块121的位置，使顶推块121不会出现行程不到位或超行程的状况。
本实施例中，动力单元4用于驱动凸轮1251沿限位凹槽的延伸方向相对滑动的同时，驱动顶推块121沿第一滑轨1231的延伸方向相对滑动，以顶推基座11上的电芯5。
在具体的使用过程中，动力单元4沿竖直方向(如图中箭头z所指方向)向上带动滑块固定板123向上运动，从而使凸轮1251沿限位凹槽的形状向下运动；顶推块121向上运动的同时，沿第一滑轨1231的延伸方向(如图中箭头y所指方向)向电芯5进行顶推。动力单元4沿竖直方向(如图中箭头z所指方向)向下带动滑块固定板123向下运动，从而使凸轮1251沿限位凹槽的形状向上运动；顶推块121向下运动的同时，沿第一滑轨1231的延伸方向(如图中箭头y所指方向)向后退回，远离电芯5。限位凹槽的形状、凸轮1251上移下移的距离都是根据电芯5精确计算得出的，最终可以精确控制顶推块121的位置。
如此，动力单元4在推动凸轮1251沿限位凹槽的延伸方向相对滑动时，通过限位凹槽对顶推块121进行限位，实现顶推块121沿第一滑轨1231的滑动对电芯5的顶推，达到顶推功能的同时，可以限制顶推块121的位置，精确控制顶推块121的位置。
在一些实施例中，请参阅图5与图6，折边机构3包括连接板31、第一折边组件32以及第二折边组件33，连接板31上设置有第二滑轨311，第一折边组件32通过第二滑块321设置在第二滑轨311上，第二折边组件33通过第三滑块331设置在第二滑轨311上，动力单元4用于驱动第一折边组件32以及第二折边组件33相互靠近或者相互远离，以对包裹在电芯5上的绝缘膜进行折边。第一折边组件32与第二折边组件33是相同对称的结构。
如此，第一折边组件32通过第二滑块321设置在第二滑轨311上，第二折边组件33通过第三滑块331设置在第二滑轨311上，动力单元4可以同时驱动第一折边组件32以及第 二折边组件33相互靠近或者相互远离，实现对电芯5上的绝缘膜进行折边，实现自动化控制折边。

动力单元4只要驱动第一铰接板34或者第二铰接板35沿竖直方向(如图中箭头z所指方向)向上向下移动，就可以驱动第一折边组件32与第二折边组件33相互远离或者相互靠近，使第一折边组件32与第二折边组件33同步运动，提高折边效率。
如此，通过第一铰接板34、第二铰接板35分别与第一铰接固定板322、第二铰接固定板332相互铰接，且第一铰接板34与第二铰接板35之间相互铰接，只要驱动第一铰接板34或第二铰接板35的移动，就可以驱动第二滑块321、第三滑块331在第二滑轨311上的相对滑动，同时驱动第一折边组件32以及第二折边组件33相互靠近或者相互远离，实现自动化控制折边，提高折边效率。
在一些实施例中，连接板31上设置有铰链导向槽312，第一铰接板34与第二铰接板35的铰接处通过导向轴在铰链导向槽312内上下移动，以带动第一折边组件32与第二折边组件33在第二滑轨311上相对滑动。
在本实施例中，铰链导向槽312沿竖直方向(如图中箭头z所指方向)延伸，可以通过铰链导向槽312对通过导向轴进行限位，使导向轴也只能沿竖直方向(如图中箭头z所指方向)上下移动，提高了第一折边组件32与第二折边组件33的稳定性。
如此，通过铰链导向槽312对导向轴进行限位，只要驱动导向轴在铰链导向槽312内上下移动，就可以带动第一折边组件32与第二折边组件33通过第二滑块321、第三滑块331在第二滑轨311上的相对滑动，实现第一折边组件32与第二折边组件33相互靠近或者相互远离，提高折边的稳定性。
在本实施例中，动力单元4用于驱动导向轴在铰链导向槽312内上下移动的同时，驱动顶推块121对基座11上的电芯5进行顶推。
在具体的使用过程中，动力单元4沿竖直方向(如图中箭头z所指方向)向上带动滑块固定板123向上运动，实现顶推块121向电芯5进行顶推；同时动力单元4沿竖直方向(如图中箭头z所指方向)带动导向轴向上运动，实现第一折边组件32与第二折边组件33相互远离；
动力单元4沿竖直方向(如图中箭头z所指方向)向下带动滑块固定板123向下运动，实现顶推块121向电芯5向后退回，远离电芯5；同时动力单元4沿竖直方向(如图中箭头z 所指方向)带动导向轴向下运动，实现第一折边组件32与第二折边组件33相互靠近，从而实现一个动力单元4同时带动两个机构运动，减少了一个驱动单元，节省成本，提高生产效率。
如此，通过动力单元4可以带动两个机构的运动，可以带动第一折边组件32以及第二折边组件33进行折边，顶推块121对基座11上的电芯5进行顶推，可以减少一个驱动单元，节省零部件。
在一些实施例中，请参阅图7，定位机构2包括限位底座23以及设置在限位底座23上的第一限位块21，第一限位块21包括用于限制电芯5在水平方向上移动的第二限位部211以及第三限位部212。

在一些实施例中，定位机构2还包括设置在限位底座23上的第二限位块22，第二限位块22用于限制电芯5在竖直方向上的移动。第二限位块22上方为电芯5的防爆阀做了避让空间。如此，通过第二限位块22用于限制电芯5在竖直方向上的移动，实现对电芯5在竖直方向上的限位，保证电芯5的位置是固定的。
如此，本实施例通过第一限位部122，顶推块121的移动位置被第一限位部122限位；顶推块121不会出现行程不到位或超行程的状况，而造成电池推不到位或撞伤电芯5，有效减少电芯5撞伤引起的安全事故。
