 本发明的实施方式
在下文的描述中，给出了大量具体的细节以便提供对本发明更为彻底的理解。然而，对于本领域技术人员而言显而易见的是，本发明可以无需一个或多个这些细节而得以实施。在其他的例子中，为了避免与本发明发生混淆，对于本领域公知的一些技术特征未进行描述。
电力能源产业的兴起，使得锂电池动力装置受到了大众的青睐，由于市场监管部门对锂电池生产厂家的监管不力，市场上生产锂电池的厂商参差不齐，锂电池起火事故频发受到了社会的关注，锂电池起火原因最为常见的原因是生产工艺导致的内部隔膜损坏，因此在检测生产线上经常能将内部隔膜损坏的锂电池筛选出来，锂电池起火首先内部燃烧，所以内部肉眼未能分别的劣质锂电池仍然在生产线上传送，造成了发现问题电池处理的滞后性，申请人发现现有的一些中小企业在生产过程中缺乏对员工锂电池消防知识的培训，进而导致锂电池在出现起火时未使用正确的消防方法对起火的锂电池进行灭火且专用锂电池灭火的设备少或者距离问题锂电池远无法起到及时性灭火，造成后期的火势蔓延，其次锂电池燃烧时间短速度块，发现不及时可能会导燃生产线上的其他锂电池燃烧，进而增加灭火的难度。
如图1至图7所示的一种具有消防装置的锂电池生产线，包括：锂电池传送机体1、基座10、支架11、基板12、流水线传送架14、第一传送带组16、第一驱动电机组17、消防装置2、消防传送架20、第二传送带组21、第二驱动电机组22、直线导轨组30、底座31、机械臂32、第一转动关节320、液压举升杆3201、第二转动关节321 、旋转电机322、旋转臂323、下料夹具33、箱体本体4、铰接门40、气动合页装置41、铰接座410、行程气缸411、活塞杆412、水箱42、按压装置43、升降气缸430、按压板431、密封边框44、挡条45、空隙46、压力传感器47、托盘48、锂电池49。
锂电池传送机体1用于传送经过电性检测后的锂电池，通过电性检测后的锂电池，锂电池通电后导致内部升温，带来材料反应扩大，较长时间的外部短路一般会导致电路中的连接薄弱点烧毁，因此电池的内部无氧燃烧是很难第一时间发现的；通过在锂电池传送机体1的下方设置消防装置2用以及时响应锂电池燃烧问题，红外摄像头设置在锂电池传送机体1的上方对传送的锂电池进行检测，下料装置传动安装在锂电池传送机体1上的一侧跟踪问题电池并将问题电池夹取至下方的消防装置2中。
本发明与传统的锂电池传送机体1相比将消防装置2设置在机体下方，以便与下料装置急速响应；解决锂电池在出现起火时未使用正确的消防方法对起火的锂电池进行灭火且专用锂电池灭火的设备少或者距离问题锂电池远无法起到及时性灭火，造成后期的火势蔓延的情况。所述锂电池传送机体1包括：基座10，安装在基座10上的支架11，固定连接在传送带支架11上的基板12，固定安装在基板12上的流水线传送架14，穿插在流水线传送架14上的若干个滚动托辊，以及对称设置在流水线传送架14两侧且与滚动托辊传动连接的第一传送带组16；所述滚动托辊的一端传动连接第一驱动电机组17，进而第一驱动电机的动力经过的滚动托辊传递至传送带上，使得第一传送带组16在流水线传送架14上循环转动。
所述消防装置2包括：固定安装在基体上的消防传送架20，穿插在消防传送架20上的若干个滚动托辊，设置在消防传送架20且与滚动托辊传动连接的第二传送带组21，以及传动连接在在滚动托辊的一端的第二驱动电机组22；进而第二驱动电机组22的动力经过的滚动托辊传递至第二传送带组21上，使得第二传送带组21在消防传送架20上循环转动。
第一驱动电机组17和第二驱动电机组22均与控制系统连通，实现传送和消化的自动化智能管理。
因为锂电池起火的起点为内部着火，肉眼难以判断是否为问题电池，所以采用红外摄像头对电池进行拍摄，甄别出温度过高的电池，所述红外摄像头为全景摄像头，检测范围广所述红外摄像头与图像检测系统连通，图像检测系统进而将检测数据发送至控制系统。
所述第一传送带组16上还设有带有识别码的传送托盘和识别码扫描的定位装置，所述定位装置为激光扫描器，激光扫描器设置流水线传送架14的一侧，能够对传送托盘进行识别和定位；所述传送托盘上盛放锂电池，进而锂电池随着传送托盘一起在第一传送带组16上移动。
所述下料装置固定安装在基板12上的直线导轨组30，卡接在直线导轨上的底座31，固定安装在底座31上的机械臂32，以及固定安装在机械臂32上的下料夹具33；
所述直线导轨组30的一侧设有直线驱动装置和定位机构，定位机构为光栅组件，能够将机械臂32的位置发送至控制系统，实现对机械臂32的高精度定位；所述直线驱动装置与控制系统连通；现有的企业在锂电池起火时采用人工将锂电池防止在消防装置2中造成消防速度减慢，同时还造成人员受伤的可能，因此采用机械化的消防下料装置可以避免这一现象；所述机械臂32包括：固定连接在底座31上的第一转动关节320组件，安装在第一转动关节320上的液压举升杆3201，铰接在液压举升杆3201活塞杆412一端的第一转动关节320组件，固定连接在第二转动关节321 一端的旋转电机322，以及固定连接在旋转电机322输出端的旋转臂323，所述旋转臂323的一端固定安装下料夹具33，进而机械臂32在直线驱动装置的带动下实现夹取位置的运动；液压举升杆3201输出的动力带动第二转动关节321 进行转动和下料夹具33角度的调整，旋转电机322带动下料夹具33进行0至360°方向的旋转，使得夹取的托盘底部与防爆箱中的铰接门40对应放置，使得防爆箱能够检测到传送过来的问题电池和托盘能够触发防爆箱中的自动化装置。
一些中小企业在生产过程中缺乏对员工锂电池消防知识的培训，锂电池起火时属于无氧燃烧，一般的消防喷剂无法起到灭火作用，极端的情况下会引发爆炸的可能性，现有灭火方法将起火的锂电池拿到车间专用的水箱42中降低温度，但是取放之间对锂电池的等待、挤压和碰撞有可能会加重触发极端情况发生的机率，所以起火锂电池的取放具有一定的危险性。而且专用于锂电池的消防机器造价昂贵，部分中小企业难以负担或者购买量小。
本发明中采用一种造价更加简单的针对中小型锂电池进行灭火的消防装置2，可在起火锂电池移动期间对其进行阻燃和降温，避免极端现象的产生；防爆箱放置在第二传送带上，随第二传动带的转动在第一传送带组16的下方移动，第二传动带上同样设有定位机构，保证传送过程中的移动精度。所述防爆箱包括：箱体本体4，开设在箱体本体4上的铰接门40，以及设置在铰接门40另一侧的气动合页装置41；所述箱体本体4中设有水箱42，所述铰接门40上设有与托盘适配的挡条45；所述挡条45与铰接门40处设有空隙，所述空隙与托盘厚度相等，所述空隙的底部设有压力传感器；压力传感器电联防爆箱中控制器，如图7所示夹取的托盘底部一端与铰接门40呈一定夹角，下料夹具33松开托盘，使得托盘沿着铰接门40滑行至底部的空隙处，滑行至底部时触发空隙底部的压力传感器，压力传感器反馈至控制器，控制器带动气动合页装置41中两侧的行程气缸411开启；铰接门40向内转动使得托盘中的电池自动翻转至箱体本体4中的水箱42中；
所述气动合页装置41包括：对称安装在箱体内部两侧的铰接座410，以及连接在铰接座410上的行程气缸411，所述行程气缸411的活塞杆412连接在铰接门40的一侧；进而行程气缸411带动铰接门40进行往复的开合运动；
当放置的锂电池属于小型电池时，防止锂电池上浮；所述箱体本体4的上方设有按压装置43。所述按压装置43包括：固定安装在箱体本体4顶部的升降气缸430，以及连接在升降气缸430活塞杆412一端的按压板431所述升降气缸430的活塞杆412带动按压板431上下运动。铰接门40关闭后，控制器在控制升降气缸430向下运动将锂电池按下在水中。确保锂电池全面与水面接触，加速降温。
所述铰接门40的高度大于箱体顶部至水箱42的距离，所述铰接门40的长度与箱体本体4相等，所述铰接门40与箱体本体4闭合处设有适配的密封边框44，一是减少氧气的后期补充，其次，防止消防过程中沸腾的水外溢，造成设备的接触不良。
工作原理如下：
红外摄像头与图像检测系统连通对生产线上的锂电池进行温度摄像，如发现异常温度的锂电池对问题电池所在的托盘进行定位；图像检测系统标记并追踪问题托盘，与控制系统通信，暂停传送问题托盘处的第一传送带组16的第一驱动电机组17，启动第二驱动电机组22动力带动第二传送带组21上的防爆箱快速移动至问题托盘的下方；控制系统同时控制直线驱动装置启动，将卡接在直线导轨组30上的机械臂32运行至问题托盘处；运行至问题托盘处机械臂32液压举升杆3201和旋转电机322同时启动，调整旋转臂323上的下料夹具33位于问题托盘上方，下料夹具33夹取问题托盘，将问题托盘夹取至铰接门40上松开；问题托盘沿着铰接门40下滑，问题托盘滑行至空隙中的底部，空隙中的压力传感器检测到问题托盘，进而控制行程气缸411伸缩带动铰接门40向内运动关闭铰接门40从而使问题托盘上的锂电池翻转至水中；铰接门40关闭后控制升降气缸430启动，升降气缸430的活塞杆412带动按压板431向下运动，按压板431将锂电池按压在水中；同时启动第二驱动电机组22动力带动第二传送带组21上的将装有问题锂电池的防爆箱已送出锂电池传送机体1，并在第二传送带组21上重新放置新的防爆箱；正常开启第一驱动电机组17恢复第一传送带组16传送工序。
本发明在锂电池传送机体1中设置双传送机制，锂电池生产线与消防输送线同步设置，缩短灭火路径；在消防输送线设置结构简单，自动化程度高且响应速度防爆箱，与机械臂32联动实现自动下料灭火，不影响整个锂电池生产线正产生产效率。在锂电池传送机体1设置直线运动机构，将机械臂32设置在直线导轨组30件上同时采用与红外摄像头和定位机构通信联动实现对问题锂电池的智能化定位和无人化灭火操作；
以上结合附图详细描述了本发明的优选实施方式，但是，本发明并不限于上述实施方式中的具体细节，在本发明的技术构思范围内，可以对本发明的技术方案进行多种等同变换，这些等同变换均属于本发明的保护范围。
