Abstract:
A robot arm mounted apparatus for high speed streaming of high viscosity, two-part adhesive onto a workpiece. The apparatus employs a shortened, temperatured-conditioned mixing tube and a compact, end effector package of dispense metering equipment associated directly with the mixing tube on the end of the robot arm, rather than mounted remotely as in prior art systems. In a preferred form a pressurized cylinder, displacement rods and chambers, dispense metering valves and shortened, temperature-conditioned mixing tube are connected to one another directly in serial fashion on the end of the robot arm. The mixing tube is preferably modified with a removable, damage-resistant nozzle designed especially for streaming.

An embodiment coating system for a secondary battery includes a supply tank connected to a slot-die and configured to store a slurry, an in-line viscometer configured to measure viscosity and temperature of the slurry, a flow meter configured to measure a flow rate of the slurry, a flow rate adjustment valve configured to adjust the flow rate according to a feedback signal based on the measured flow rate, a coating bead sensor configured to detect in real time a slurry coating bead shape discharged from the slot-die to a base material, and a coating controller configured to detect a process condition change event by monitoring a slurry property and the slurry coating bead shape in real time and to control the flow rate of the flow rate adjustment valve based on reference data corresponding to a changed slurry property.
Abstract:
An adhesive dispensing system for applying liquid adhesive to a substrate using different nozzles with the same manifold is disclosed. The adhesive dispensing system includes a manifold having a body, a first clamp configured to engage the body of the manifold, a second clamp configured to engage the body of the manifold, and a nozzle. The first and second clamps secure the nozzle to the body of the manifold. The body of the manifold has a first contact surface that engages the first clamp and a second contact surface that engages the second clamp and the nozzle, where the second contact surface is angularly offset from the first contact surface.
Abstract:
Techniques herein include systems and methods for dispensing liquids on a substrate with real-time coverage control and removal control. Techniques also encompass quality control of dispense systems. Systems and methods enable visual examination of liquids progressing on a surface of a substrate. This includes capturing and/or examining stroboscopic images of movement of a given liquid on a working surface of a substrate, and then generating feedback data for modifying a corresponding dispense. Dispenses can be modified by increasing/decreasing a dispense rate and increasing/decreasing a rotational velocity of a substrate. Feedback can be generated by automated and/or manual analysis of real time progression as well as post-process analysis of collections of images.
Abstract:
A method is provided for decision support in regulating an adhesive coating applied to Yankee dryers. Online sensors are configured to continuously measure stock characteristics, and additional sensors provide actual stock flow rate and machine speed. A controller predicts potential natural coating application from a fibrous sheet generated from the stock to the Yankee dryer surface, substantially in real time, based on the measured characteristics and sensed actual machine values. An output signal may be provided to a display unit, wherein an optimal adhesive coating feed rate may be determined and displayed for operator decision support. The controller may in an automatic mode be configured to regulate the adhesive coating feed rate based on a comparison of one or more determined optimal values associated with respective actual values. The method may include identifying fiber source changes in real time, and predicting a natural coating potential based partly on predetermined correlations.
Abstract:
A fluid application system includes a source of a fluid and a first pump for supplying the fluid under pressure to an applicator having a nozzle for dispensing the fluid. A fluid collection system collects reclaimed fluid dispensed from the applicator and a second pump provides the reclaimed fluid under pressure to a return fluid pipe. The return fluid pipe has a valve system that selectively directs the reclaimed fluid to either a reusable fluid container or the applicator. The valve system may selectively direct the reclaimed fluid from the return fluid pipe to an in-line reservoir and a third pump may be used to provide the reclaimed fluid under pressure from the in-line reservoir to the applicator.
Abstract:
A sensor unit for measuring a mass flow rate of a liquid hot-melt adhesive is disclosed. The sensor unit includes a flow channel for the hot-melt adhesive, a first temperature measurement device positioned at a first position in the flow channel, a second temperature measurement device positioned at a second position in the flow channel and a heating device assigned to the second temperature measurement device, and a control unit for controlling the heating device and for measuring the mass flow rate. The controller is configured to adjust the temperature of the heating device assigned to the second temperature measurement device to a value, to determine the heating power for heating the heating device assigned to the second temperature measurement device, and to calculate the mass flow rate in the flow channel. The first and second temperature measurement devices are arranged substantially parallel to each other in the flow channel.
Abstract:
A system for dispensing hot melt adhesives, comprising an adhesive dispenser including a fluid passage leading to an outlet. The system further comprises a supply conduit fluidly connected to the fluid passage and a feeding mechanism configured to feed an elongate, flexible element of solid adhesive into the supply conduit. The system further comprises a first heating element positioned along at least a portion of the supply conduit to melt a portion of the elongate, flexible element being fed into the supply conduit and thereby form a supply of liquid adhesive within the supply conduit.
