A supply line is branched from a front end of the first circulation valve and an applying gun which is disposed in the supply line, receives a sealer, and controls the sealer discharged to the outside through a nozzle.

A dispensing apparatus includes a frame having a gantry configured to provide movement in the X axis and Y axis directions, and first and second dispensing units coupled to the gantry and configured to dispense material onto a substrate. The second dispensing unit is coupled to the gantry by an automatic adjustment mechanism. The dispensing apparatus further includes a controller configured to control the operation of the gantry, the first dispenser, the second dispenser, and the automatic adjustment mechanism. The automatic adjustment mechanism is configured to move the second dispenser in the X axis and Y axis directions to manipulate a spacing between the first dispensing unit and the second dispensing. Methods of dispensing material on the substrate are further disclosed.

A deformation verification system of a vehicle body includes a dip tank in which fluid is contained. The dip tank has a transparent window from the outside to see the inside. A moving device is configured to lower the vehicle body into the fluid, to move the vehicle body in the fluid and to raise the vehicle body. A camera is installed to detect the form of the vehicle body through the transparent window.

An apparatus for dispensing a viscous fluid includes a dispenser module including a nozzle which dispenses a viscous fluid according to a profile; a robot module configured to move the nozzle according to the profile; a vision module configured to generate an image by photographing a workpiece to which the viscous fluid is dispensed; and a control module configured to integrally control the dispenser module and the robot module based on the image received from the vision module to dispense the viscous fluid according to the profile, wherein, in order to generate the profile, the control module provides a user with an interface which enables the user to input a pattern of the viscous fluid in such a way as to draw the pattern on the image. A user may freely generate a pattern of a viscous fluid, and may accurately dispense the viscous fluid according to the generated pattern.

A hot melt adhesive system includes an adhesive supply for receiving solid or semi-solid hot melt adhesive, and a heater associated with the adhesive supply for melting the solid or semi-solid hot melt adhesive into liquid hot melt adhesive. An adhesive tracking system monitors an output of the liquid hot melt adhesive, and includes a flow meter having a flow inlet and a flow outlet. The flow meter measures an amount of the adhesive flowing out of the flow outlet. A product detector may be used to sense a presence of a product to which the adhesive is applied. A controller then determines the total amount of the liquid adhesive dispensed and the average amount of liquid adhesive dispensed per product.

Methods for simultaneously dispensing a first fluid pattern at a first dispense region with a first applicator and a second fluid pattern at a second dispense region with a second applicator. The first and second applicators are moved toward their respective dispense regions with a positioner. While dispensing, the second applicator is moved relative to the first applicator in a direction or directions parallel to a first axis, a second axis, and/or a third axis, the axes being mutually orthogonal. The first dispense region may be provided with a unique first tilt and/or a unique first contour relative to the reference plane and along the third axis. Systems for dispensing fluid include a primary positioner supporting a first applicator, and a secondary positioner coupled to the primary positioner and supporting a second applicator and configured to move the second applicator relative to the first applicator.

In manufacturing a laminated iron core by laminating and bonding iron core laminates blanked from a sheet steel strip into a prescribed profile, the adhesive agent can be applied to the iron core laminates in a stable manner without regard to the arrangement and the number of the application spots on each iron core laminate. The metallic die machine (1) is provided with an adhesive agent application unit (12) configured to apply an adhesive agent to a prescribed area of the sheet steel strip (W) corresponding to the iron core laminates (2), and the adhesive agent application unit is provided with a casing (44) defining a plurality of adhesive agent storage chambers (55-57) for storing the adhesive agent before the adhesive agent is applied to the prescribed area. The casing is provided with a plurality of ejection orifices (H1 to H3) each communicating with a corresponding one of the adhesive agent storage chambers and configured to eject the adhesive agent.

A deformation verification system of a vehicle body includes a dip tank in which fluid is contained. The dip tank has a transparent window from the outside to see the inside. A moving device is configured to lower the vehicle body into the fluid, to move the vehicle body in the fluid and to raise the vehicle body. A camera is installed to detect the form of the vehicle body through the transparent window.

Method of dispensing fluid are disclosed. The method initially determines, based upon an image of a first electronic substrate, that a first or a second dispense region is misaligned relative to the other of the first or the second dispense region. Fluid is dispensed from a first applicator while moving the first applicator using a primary positioner on the first electronic substrate to form a first fluid pattern. Fluid is simultaneously dispensed from a second applicator while moving the second applicator using the primary positioner and a secondary positioner. The method then determines, based upon an image of a second electronic substrate, that a first and a second dispense region of the second electronic substrate are aligned relative to one another. Fluid is simultaneously dispensed from the first applicator and the second applicator while moving the first applicator and the second applicator together using the primary positioner with first applicator.

Methods of dispensing fluid are disclosed. A first applicator is positioned above a first dispense site at a first dispense region of a first electronic substrate by moving the first applicator using a primary positioner. A second applicator is simultaneously positioned above a first dispense site at a second dispense region of the first electronic substrate by moving the second applicator together with the first applicator using the primary positioner and moving the second applicator relative to the first applicator using a secondary positioner. It is then determined that the first or the second dispense region is misaligned relative to the other of the first or the second dispense region. Fluid is dispensed from the first applicator while moving the first applicator using the primary positioner to form a first fluid pattern at the first dispense region and fluid is simultaneously dispensed from the second applicator while moving the second applicator using the primary positioner and the secondary positioner.
