所述抓取组件包括四排抓齿，所述气缸驱动与其对应的抓齿来回摆动，所述抓齿的摆动角度为90°，所述抓齿包括L形固定齿和设置在固定齿顶部的封闭组件；
所述封闭组件包括圆柱形主体、圆环形橡胶圈和两个呼吸膜，所述主体内部设有条形空腔，所述空腔通过设置在固定齿内部的通孔与外部空压机连通，所述橡胶圈设置在主体一端，所述橡胶圈内圈的直径大于空腔的直径，所述主体与橡胶圈的连接处设有喇叭口，其中一个呼吸膜设置在橡胶圈内部，另一个呼吸膜设置在空腔远离橡胶圈的一端。
为了防止封闭组件戳破袋子，所述橡胶圈远离主体的一侧设有弧形倒角。
为了提高主体的承重能力，并且减轻整个机械抓手的整体重量，所述主体为玻璃钢复合材料。
为了更好地抓取袋子，所述封闭组件位于两个正对的固定齿之间。
本发明的有益效果是，该用于码垛系统的智能机器人抓手通过吸盘式固定连接，能够实现机械抓手对袋子的自由抓取和固定，并且采取玻璃钢为主体材料，不仅能够有效减轻整体重量，而且能够对袋子起到有效的支撑，不仅提高了抓取能力，还提高了工作效率。

具体实施方式
现在结合附图对本发明作进一步详细的发明。这些附图均为简化的示意图，仅以示意方式发明本发明的基本结构，因此其仅显示与本发明有关的构成。
如图1-3所示，一种用于码垛系统的智能机器人抓手，包括支撑组件和固定在支撑组件上的抓取组件和动力组件；
所述支撑组件包括四块定位板1，四块定位板1位于同一平面上且四块定位板1关于同一个点中心对称，相邻的两块定位板1之间通过横梁2固定连接，所述定位板1沿横梁2滑动；
所述动力组件包括四个气缸3，四个气缸3分别固定在四块定位板1上，所述抓取组件有四个，四个抓取组件分别对应设置在四个气缸3下方，所述气缸3驱动与其相对应的抓取组件；
所述抓取组件包括四排抓齿，所述气缸3驱动与其对应的抓齿来回摆动，所述抓齿的摆动角度为90°，所述抓齿包括L形固定齿4和设置在固定齿4顶部的封闭组件5；
所述封闭组件5包括圆柱形主体51、圆环形橡胶圈53和两个呼吸膜54，所述主体51内部设有条形空腔52，所述空腔52通过设置在固定齿4内部的通孔与外部空压机连通，所述橡胶圈53设置在主体51一端，所述橡胶圈53内圈的直径大于空腔52的直径，所述主体51与橡胶圈53的连接处设有喇叭口，其中一个呼吸膜54设置在橡胶圈53内部，另一个呼吸膜54设置在空腔52远离橡胶圈53的一端。
为了防止封闭组件5戳破袋子，所述橡胶圈53远离主体51的一侧设有弧形倒角。
为了提高主体51的承重能力，并且减轻整个机械抓手的整体重量，所述主体51为玻璃钢复合材料。
为了更好地抓取袋子，所述封闭组件5位于两个正对的固定齿4之间。
封闭组件5与外部空压机连通，在对袋子实施抓取的过程中，气缸3驱动抓齿对袋子进行抓取，当袋子位于抓齿之间后，两个正对的封闭组件5的橡胶圈53 正好抵靠在一起，然后空压机工作，吸走空腔52内部的空气，使得两个橡胶圈53之间密封连接，在压强的作用下，使得两个密封组件牢牢地吸在一起，不仅能够防止袋子掉落，而且还对抓取的袋子实现了一个抓紧的作用。
与现有技术相比，该用于码垛系统的智能机器人抓手通过吸盘式固定连接，能够实现机械抓手对袋子的自由抓取和固定，并且采取玻璃钢为主体51材料，不仅能够有效减轻整体重量，而且能够对袋子起到有效的支撑，不仅提高了抓取能力，还提高了工作效率。
