Abstract: An overspray-free paint system includes: a paint robot including an overspray-free paint applicator; and a first fixture robot for lifting and orienting a fixture assembly relative to at least one of the paint robot and the overspray-free paint applicator, the fixture assembly configured to hold an object to be painted by the overspray-free paint applicator, the first fixture robot including a first gripper configured to grab a first portion of the fixture assembly, and the first fixture robot configured to lift and orient the fixture assembly via the first gripper.

Abstract: A robotic lifting and orienting system for an overspray-free paint system includes: a base coupled to wheels; and an automated carrier coupled to the base. The automated carrier includes: a fixture assembly configured to hold an object to be painted; one or more manipulators configured to move the fixture assembly relative to a paint robot; a propulsion system connected to the wheels and configured to move the robotic lifting and orienting system; and a control module configured to control the one or more manipulators and the propulsion system to control positioning and orienting of the object relative to at least one of the paint robot and an overspray-free paint applicator of the paint robot.

Abstract: A graphene heating chip includes a substrate, an insulating layer, a graphene film, and a plurality of electrodes. The substrate has two opposite a first surface and a second surface, and the substrate defines a through hole. The insulating layer is suspended on the substrate. The insulating layer covering the through hole and not in direct contact with the first surface is defined as a window, and a plurality of grooves are formed on the window. The graphene film covers the window, and the graphene film includes a first graphene film portion and a second graphene film portion, and the first graphene film portion and the second graphene film portion are spaced apart from each other. The plurality of electrodes are located on the surface of the insulating layer away from the substrate. The present application also provides a method for making the graphene heating chip.

Abstract: Provided is an apparatus for fabricating a flexible display screen. The apparatus for the flexible display screen includes a roller mechanism and a jig, wherein the jig includes a bearing surface configured to bear a flexible display panel, the bearing surface being a curved surface; and the roller mechanism includes a roller, an axis of the roller being parallel to an element line of the bearing surface, and the roller being configured to roll on the bearing surface along a directrix of the bearing surface.

Abstract: A stator and a rotor are mounted inside a case of a permanent magnet motor, and separate the inner cavity of the case into a first inner cavity and a second inner cavity. An air gap is formed between an inner circle surface of the stator and an outer circle surface of the rotor. Axial ventilation holes in communication with the first inner cavity and with the second inner cavity are disposed in teeth of a stator core. The rotor comprises a rotor core and rotor pressing rings disposed in an axial direction at both sides of the rotor core. A partition is disposed between the rotor core and at least one of the rotor pressing rings. An outer edge of the partition extends into the air gap, thus enhancing the air blocking effect and realizing a higher cooling efficiency.

Abstract: A stator and a rotor are mounted inside a case of the permanent magnet motor, and separate the inner cavity of the case into a first inner cavity and a second inner cavity. Axial ventilation holes in communication with the first inner cavity and with the second inner cavity, are disposed in teeth of a stator core of the stator, and each axial ventilation hole is a taper hole extending in a height direction of each tooth. The width of one end of the axial ventilation hole, which is close to a head of the tooth, is greater than the width of the other end of the axial ventilation hole, which is close to a root of the tooth. The taper holes enable fluid to fully carry out exchange heat at the teeth where heat is generated most intensively.

Abstract: Disclosed are a terminal mechanism, a permanent magnet adjustable-speed motor and a centrifugal refrigeration compressor. The terminal mechanism comprises a terminal board, power supply connectors and sealing rings; the terminal board is made of steel, and the magnetic permeability ? of the steel is less than or equal to 1.31×10?6 H/m. The terminal board is a flat board having an upper surface and a lower surface, and is provided with terminal holes thereon. The sealing rings are sleeved on the power supply connectors. The power supply connectors are fixed on the terminal board through the terminal holes. The sealing rings are in sealing engagement with the terminal board, so as to reduce heat generated by an electric eddy current.
