摘要： A fluid dispensing apparatus having a controller which operates to modify a tool speed signal from a robot and to generate a corrected signal to the dispenser nozzle flow controller which compensates for non-linear flow characteristics of fluids, such as non-Newtonian adhesive fluids, to maintain uniform bead size as the tool speed varies. The corrected tool speed signal is generated by computing the ideal flow for the tool speed signaled, comparing the computed flow with actual flow data stored in a memory using linear interpolation of data between the stored values, and generating a control signal modified in accordance with the comparison. The stored data is acquired by operation in a calibration mode wherein a series of standard signals is sent to the fluid controller while the actual flow at each signal level is measured and stored in a table. The method of operation corrects non-linear flow phenomena such as the shear-thinning effect.

摘要： A method of controlling and operating a fluid dispensing apparatus is provided which modifies a tool speed signal from a robot and generates a corrected signal to a dispenser nozzle flow controller to compensate for non-linear flow characteristics of fluids, such as non-Newtonian adhesive fluids, to maintain uniform bead size as the tool speed varies. The corrected tool speed signal is generated by computing the ideal flow for the tool speed, comparing the computed flow with actual flow data stored in memory using linear interpolation of data between the stored values, and generating a control signal modified in accordance with the comparison. The stored data is acquired by operation of the apparatus in a calibration mode wherein a series of standard signals is sent to the fluid controller while the actual flow at each signal level is measured and stored in a table. The method corrects for non-linear flow phenomena such as that known as the shear-thinning effect that is flow rate dependent.

摘要翻译： 提供了一种控制和操作流体分配装置的方法，其修改来自机器人的工具速度信号，并且产生校正信号到分配器喷嘴流量控制器以补偿诸如非牛顿粘合剂流体之类的流体的非线性流动特性 ，以便在刀具速度变化时保持均匀的珠粒尺寸。 通过计算刀具速度的理想流量来生成校正的刀具速度信号，将计算出的流量与存储在存储器中的数据的存储器中的实际流量数据进行比较，并生成根据比较修改的控制信号。 存储的数据是通过在校准模式下操作该装置获得的，其中一系列标准信号被发送到流体控制器，同时测量每个信号电平的实际流量并将其存储在表中。 该方法校正非线性流动现象，例如称为流速依赖的剪切稀化效应。
