Description

齿轮式定位机构 技术领域
本实用新型涉及机械定位设备技术领域，尤其涉及一种齿轮式定位机构。
背景技术
随着地球上的石油和煤炭等资源日益减少，开发自然界的新能源已经成为当务之急，其中太阳能的利用已经越来越普遍，太阳能电池作为将太阳能转换成电能的重要部件，对太阳能电池的研究已经越来越迫切。
现有的CIGS薄膜太阳能电池，为高效太阳能电池的一种，在制造CIGS薄膜太阳能电池时，需要用到玻璃衬底，并在玻璃衬底上镀膜，为了提高镀膜效率，玻璃衬底的尺寸一般都较大，在镀膜完成后，进行封装之前，需要将一个大尺寸的玻璃衬底切割成相同大小的两半。
目前，在切割玻璃采用靠边定位的方式找准玻璃的中心线，其原理如图1所示。玻璃3传送到位后，定位块1会挡住玻璃3，然后气缸2同时动作将玻璃3推至与定位块1对齐，此时中间的虚线位置即为切割线，由于切割线处的切割刀位置不变，因此在玻璃尺寸精确的情况下，这种对齐方式精度高，但是在玻璃尺寸有误差或者玻璃镀膜后翘曲度较大的情况下会导致切割后两块玻璃尺寸不一致。
请参考图1，玻璃定位完成后，沿切割线将玻璃分成玻璃A和玻璃B，如果玻璃尺寸为标准尺寸，切割后玻璃A和玻璃B的宽度相同。若玻璃的尺寸偏小，切割后玻璃A的宽度将比玻璃B的宽度大；若玻璃的尺寸偏大，切割后玻璃A的宽度将比玻璃B的宽度小。那么后续在封装时，会由于两块玻璃的尺寸不一致，导致封装精度受影响。

具体地，第一齿条21和第二齿条22可以通过滑轨滑动连接在底板10上，具体地，在底板10上设置有第一滑轨11和第二滑轨12，第一滑轨11和第二滑轨12相互平行；第一齿条21滑动连接于第一滑轨11上，第二齿条22滑动连接于第二滑轨12上。齿轮组23转动时，带动第一齿条21和第二齿条22分别沿着第一滑轨11和第二滑轨12移动，第一滑轨11和第二滑轨12一方面起到连接作用，另一方面起到导向的作用。
进一步地，齿轮组23包括主动齿轮231、第一从动齿轮232和第二从动齿轮233；主动齿轮231与底板10转动连接，第一从动齿轮232与第二从动齿轮233均与主动齿轮231相啮合；第一齿条21与第一从动齿轮232相啮合，第二齿条22与第二从动齿轮233相啮合；主动齿轮231向第一方向转动时，第一从动齿轮232和第二从动齿轮233同时向与第一方向相反的第二方向转动；第一齿条21与第二齿条22同时向相反方向移动。
请参考图2，可见，主动齿轮231逆时针旋转时，第一从动齿轮232和第二从动齿轮233均顺时针旋转，第一齿条21向右移动，带动第一定位组件30向右移动；第二齿条22向左移动，带动第二定位组件40向左移动。相反地，主动齿轮231顺时针旋转，第一从动齿轮232和第二从动齿轮233均逆时针旋转，第一齿条21向左移动，带动第一定位组件30向左移动；第二齿条22向右移动，带动第二定位组件40向右移动。以此保证第一齿条21和第二齿条22的移动距离相同，从而有利于精确的找到玻璃的中心线。
为提高工作效率，可以使用自动化部件控制主动齿轮231旋转，具体地，驱动组件20还包括用于主动齿轮231转动的第一驱动元件24，第一驱动元件24固定于底板10上；第一驱动元件24的驱动端与主动齿轮231连接。优选地，第一驱动元件24为电机。并且第一驱动元件24通过固定支架25固定于底板10的底部。固定支架25包括纵杆和横杆，纵杆与底板10的底部固定连接，横杆连接在多个纵杆之间，第一驱动元件24连接在纵杆上。
具体地，第一定位组件30包括第一连接块31和第一定位杆32；第一连接块31与第一齿条21固定连接，第一定位杆32与第一连接块31固定连接；第二定位组件40包括第二连接块41和第二定位杆42；第二连接块41与第二齿条22固定连接，第二定位杆42与第二连接块41固定连接。
其中，第一连接块31和第二连接块41起到连接的作用，并且第一连接块31和第二连接块41也分别滑动连接在第一滑轨11和第二滑轨12上，以进一步地确保移动过程中的平稳。请参考图2，第一定位杆32和第二定位杆42用于定位玻璃的两侧边，第一定位杆32和第二定位杆42均与第一齿条21和第二齿条22相垂直，从而在玻璃移动的方向，对玻璃的两侧边进行定位，以便于快速找到玻璃中心线。
优选地，第一定位组件30还包括第一定位轮33；第一定位轮33通过第一导柱34与第一定位杆32连接，第一导柱34能带动第一定位轮33上下移动；第二定位组件40还包括第二定位轮43，第二定位轮43通过第二导柱44与第二定位杆42连接，第二导柱44能带动第二定位轮43上下移动。
放置玻璃时，使第一导柱34和第二导柱44上升，从而带动第一定位轮33和第二定位轮43升高，玻璃放置在底板10上之后，玻璃的一侧边与第二定位杆42接触，此时使第二导柱44下降，使得第二定位轮43的底部压在玻璃的侧边上，然后开启电机带动齿轮组23旋转，玻璃随着第二定位组件40的移动而移动，当玻璃的另一侧边与第二定位杆42接触时，使第一导柱34下降，使得第二定位轮43的底部压在玻璃的另一侧边上，对玻璃进行压紧定位，然后启动切割刀70进行切割。
进一步地，齿轮式定位机构还包括第二驱动元件50和第三驱动元件60；第二驱动元件50和第三驱动元件60均连接在底板10的底部；第二驱动元件50的驱动端与第一导柱34连接，用于驱动第一导柱34上下移动，从而使得第一导柱34带动第一定位轮33上下移动； 第三驱动元件60的驱动端与第二导柱44连接，用于驱动第二导柱44上下移动，从而使得第二导柱44带动第二定位轮43上下移动。优选地，上述第二驱动元件50和第二驱动元件50均为气缸，气缸的缸体固定在底板10的底部，气缸的连杆分别与第一定位轮33和第二定位轮43相连。
本领域技术人员可以理解的是，由于第一定位轮33和第二定位轮43分别与第一定位杆32和第二定位杆42相连，因此第一定位杆32和第二定位杆42左右移动时，第一定位轮33和第二定位轮43也同时左右移动，相应地，第一导柱34与第二导柱44也左右移动。
因此，为了便于第一导柱34和第二导柱44左右移动，底板10上开设有第一滑槽和第二滑槽，第一滑槽和第二滑槽均与第一滑轨11相平行；第一导柱34的底端依次穿过第一定位杆32和第一滑槽与第二驱动元件50连接；第二导柱44的底端依次穿过第二定位杆42和第二滑槽与第三驱动元件60连接；第一齿条21移动时，第一导柱34沿着第一滑槽移动；第二齿条22移动时，第二导柱44沿着第二滑槽移动。
