In one example, a melter has a housing, a heater, a vent, and a filter medium. The housing defines a receiving space that supports adhesive therein. The heater heats the receiving space of the housing to melt the adhesive. The melter defines an adhesive inlet therein that receives adhesive carried by a transport supply gas into the receiving space. The vent extends through a wall of the melter and permits the transport supply gas to escape from the melter. The filter medium is supported in the vent to capture particulates from the transport supply gas escaping the receiving space, and is positioned relative to the receiving space such that heat from the receiving space causes the particulates captured by the filter medium to melt and fall into the receiving space.

An adhesive dispensing device (10) includes a melt module (12) including a housing (78) that defines a receiving space to receive adhesive and a heater (114) to heat the housing to melt the adhesive, and a control module (14) releasably connected to the melt module. The control module includes a controller (36) to automatically recognize a characteristic associated with the melt module and operate the melt module using instructions stored on the controller that correspond to the characteristic of the melt module. A method of operating the adhesive dispensing device is also disclosed.

A substrate treating apparatus and a substrate treating method. The substrate treating apparatus includes a treating unit and a controller. The treating unit includes a substrate holder, a rotation driving unit, a treatment liquid supplying unit, a liquid collecting unit, and a guard driving unit. The substrate holder holds a substrate in a horizontal posture. The rotation driving unit rotates the substrate holder. The liquid collecting unit includes a first guard, a second guard, and a liquid inlet. The first guard and the second guard are arranged so as to surround the substrate holder laterally. The liquid inlet is defined by the guards. The liquid inlet is open toward the substrate held by the substrate holder. The guard driving unit moves the second guard in a vertical direction. The controller controls the guard driving unit in accordance with the shape of the substrate held by the substrate holder, thereby changing a height position of an upper end of the liquid inlet.

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.

The present disclosure provides a filter device and a photoresist coating system, and the filter device includes: a liquid storage tank, configured to hold photoresist to be filtered; a stirring structure, including a stirring tank and a stirring assembly at least partially received in the stirring tank; a first pipeline, one end of the first pipeline communicates with the liquid storage tank, and the other end of the first pipeline communicates with the stirring tank; a first filter assembly, provided on the first pipeline and located between the liquid storage tank and the stirring tank; a first pressure detection assembly, provided on the first pipeline and configured to detect a pressure of the photoresist in the first pipeline; and a second pipeline, one end of the second pipeline communicates with the stirring tank, and the other end of the second pipeline communicates with the coating device.

The disclosure relates to a hot glue method for applying hot glue onto labels and/or containers using the hot glue unit, and to a glue vapor suction device for a labeler, comprising a suction opening, a suction, a pre-separation unit, a filter unit, and an outlet opening, which are arranged in communication with one another successively by lines in a direction of flow of the glue vapor through a fluid line system. At least one sensor system is arranged in the suction for verifying proper operation of the glue vapor suction. A hot glue unit is provided comprising at least one glue roller, a glue container, and a housing in which the glue roller is arranged. The hot glue unit comprises a glue vapor suction device connected to the housing for sucking glue vapor from the interior of the housing before it exits the hot glue unit.

A substrate processing apparatus includes a substrate support unit including a chuck for supporting a substrate, a fluid supply unit that supplies a processing fluid to the substrate, and a recovery unit surrounding the chuck and recovering the supplied processing fluid. The substrate support unit includes an antistatic material in which milled carbon fibers (MCF) are blended into a perfluoroalkoxy alkane (PFA) resin.

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.

Inspection devices and methods for inspecting an adhesive pattern on a substrate are disclosed. The inspection device includes at least one sensor having a heat sensor head for detecting a pattern of the adhesive bead, and a controller. Reference data representing a desired adhesive pattern is initially provided to a controller. A predetermined tolerance range for the desired adhesive pattern is also provided to the controller. An adhesive bead is discharged onto a substrate from a nozzle. A pattern of the discharged adhesive bead is then detected by the sensor when the substrate moves. Signals representing the detected pattern are received from the sensor at the controller. Finally, the signals representing the detected adhesive pattern are compared to the tolerance range of the desired adhesive pattern.

A liquid application unit and a liquid application apparatus are provided, for which a liquid material can be readily resupplied or replaced. A liquid application unit includes: a plurality of application needle units each including an application needle and a liquid material container in which the liquid material is stored and from which the liquid material is supplied to the application needle; and a first driving unit configured to move the application needle relative to a target and the liquid material container in a first direction. The plurality of application needle units are integrally attachable to and detachable from the first driving unit.
