A system for preventing overflow of adhesive applied to a PET rolling film includes a drive unit, a detection unit, and a processing unit. The detection unit detects whether UV adhesive spread on a PET film flows out to limit lines on the PET film. The detection unit generates trigger signal upon detecting that the UV adhesive on the PET film flows to any of the limit lines, and then transmits the trigger signal to the processing unit. The processing unit controls the drive unit to accelerate a rotational speed of a guide roller for the PET film upon receiving the trigger signal from the detection unit, so as to accelerate a moving speed of the PET film.

A metering rod assembly including a body for accommodating a metering rod insert and configured to clamp the metering rod and/or metering rod insert without the use of an auxiliary clamping device, such as a pressure tube or the like. A rod bed insert is supported in a tapered channel of a body whereby a clamping action is created during use. In another embodiment, the body includes a hinge portion that facilitates relative rotation between upper and lower jaws to create a clamping action during use.

A grid guidance device for guiding battery grids to a battery pasting machine. The grid guidance device includes an assemblage of components that work together to adjust a position of a platform relative to a pasting orifice of the battery pasting machine. The platform receives the battery grids over it amid use of the grid guidance device. Multiple electric motors can be provided to rotate shafts for making the position adjustments. The position adjustments can involve one or more of the following: lateral positioning of the battery grids relative to the pasting orifice, advancement and retraction positioning of the platform relative to the pasting orifice, and/or raising and lowering positioning of the platform relative to the pasting orifice.

The invention relates to a roller (1) for use in a dry coating process to produce electrodes, comprising: a roller core (3) consisting of a core material; a roller shell (4) consisting of a shell material, the roller shell surrounding the roller core at least in sections; the shell material having a greater hardness than the core material; and the roller core including a device for tempering the roller shell.

The disclosure relates to a coating apparatus for applying a monolayer layer of particles to a receiving surface. The apparatus comprises a pressurized air source, an application chamber partially bounded by the receiving surface into which an air stream is delivered by the air source, an air return path for returning air from the application chamber to an intake of the air source to form an air circulation loop, and a dosing device for introducing particles to be coated onto the receiving surface into the air circulation loop, a particle deflector being positioned in the path of the air stream to break up agglomerated particles carried by the air stream prior to coating the receiving surface with the particles. A method of applying a layer of particles is also provided, as well as printing systems benefiting from the present coating apparatus.

A battery paste application tooling assembly includes a hopper, a connector assembly, and a clamp assembly. The battery paste application tooling assembly can be equipped in a pasting machine. The hopper receives battery paste material. The hopper has an orifice plate with an orifice therein. The connector assembly is engageable with the orifice plate and disengageable therefrom. The clamp assembly is movable between a first position and a second position. In the first position, the clamp assembly releasable secures the orifice plate to the hopper. In the second position, the clamp assembly permits removal of the orifice plate from the hopper.

A production apparatus of an electrode active material layer, comprising: a support unit; a feeding unit feeding prescribed granulated particles on or above the support unit; a first conveying unit; a squeegee unit; a first stock guide; a second stock guide; a first position measurement unit; a second position measurement unit; a rolling unit; a first gap adjustment unit; a second gap adjustment unit; and a control unit. The first position measurement unit measures a distance D1. The second position measurement unit measures a distance D2. The control unit causes the first gap adjustment unit to adjust a gap G1 based on a difference between the gap G1 obtained based on the distance D1 and a gap threshold T1 and causes the second gap adjustment unit to adjust a gap G2 based on a difference between the gap G2 obtained based on the distance D2 and a gap threshold T2.

A system and methods for manufacturing a dry electrode for an energy storage device are disclosed. The system includes a first dry electrode material delivery system configured to deliver a dry electrode material, a first calendering roll, a second calendering roll, and a controller. The second calendering roll is configured to form a first nip between the first calendering roll and the second calendering roll. The first nip is configured to receive the dry electrode material from the first dry electrode material delivery system, and form a dry electrode film from the dry electrode material. The controller is configured to control a rotational velocity of the second calendering roll to be greater than a rotational velocity of the first calendering roll.

An induction heater system for manufacturing an electrode for various energy storage devices may include a power generator configured to generate power. The system may also include induction heating coils disposed adjacent to ends of at least one of a first roller or a second roller and configured to generate an electromagnetic field based on the power. The system may further include a heater plate surrounding the ends of at least one of the first or second rollers and configured to receive the electromagnetic field and generate an eddy current that generates heat on the heater plate based on electromagnetic field induction such that the generated heat is transferred to the one or both ends of at least one of the first roller or the second roller via thermal conduction.

A coating apparatus configured to coat a peripheral surface of an endless member with a coating liquid, includes: a holding member configured to hold the endless member; an impregnation member configured to be impregnated with the coating liquid and configured to coat the endless member with the coating liquid in contact with the endless member; a nozzle member configured to eject the coating liquid onto the endless member; a rotating mechanism configured to rotate the holding member relative to the impregnation member and the nozzle member; and a moving mechanism configured to move the holding member relative to the impregnation member and the nozzle member so that the coating liquid is ejected from the nozzle member onto the endless member in a region where the coating liquid is already coated by the impregnation member.
