There are two, three, four and five axes of automatic dispensing machines in common use. Among them, the three-axis series dispensing machine is the most common one, which is divided into X Y Z axis. General three-axis dispensing machine can meet the needs of production, four-axis dispensing machine is to add a rotating shaft, so many problems that three-axis dispensing machine can not solve four-axis dispensing machine can solve.

　　其实就几轴而言的话，不能叫点胶机，只能叫机械手臂。三轴点胶机的只能进行标准的X,Y,Z移动，如产品点胶的位置在侧边，可能需要点胶头倾斜点胶，那就需要4轴点胶机的(R轴)进行工作;如产品需要进行两面点胶的话，那就需要产品进行翻转完成，也就需要5轴机械臂(也就是所谓的工业机器人)。

　　In fact, as far as several shafts are concerned, it can't be called dispensing machine, but mechanical arm. The three-axis dispenser can only carry out standard x, y and Z movements. If the product dispensing position is on the side, the dispensing head may need to be tilted for dispensing, then it needs to work on the (R-axis) of the four-axis dispenser; if the product needs to carry out two-sided dispensing, then it needs to turn the product, which requires a five axis mechanical arm (also known as the industrial robot).

　　四轴点胶机相比较三轴点胶机：具有画点、直线、多段线、三维圆弧(空间圆弧)、圆、椭圆、跑道、距形、螺旋线、涂布、自动圆角、不规则三维样条曲线等图形元素，完全实现360度旋转点胶。

　　Compared with the three-axis dispensing machine, the four-axis dispensing machine has drawing points, straight lines, polylines, three-dimensional arcs (spatial arcs), circles, ellipses, runways, pitch shapes, helices, coating, automatic fillets, irregular three-dimensional splines and other graphic elements, fully realizing 360 degree rotation dispensing.
