Coating machines are often used in industrial production. During the production process of the coating machine, it is often necessary to use a loading device to load coils such as film or paper into the coating machine. Before loading the coating machine, the loading device needs to place the coil in the loading device. Currently, the coil is mostly placed manually at the designated position of the loading device, and then the supporting shaft of the loading device is used to support the coil so that the loading device can deliver the coil to the coating machine. However, this loading method is less efficient.

For another example, when there are multiple components C, the multiple components C are C1, C2, ..., C N , when one of the C components, such as C2, is closer to the B component than other C components, then B is adjacent to C2, or it can be said that C2 is adjacent to B.

[0092] The linear drive module mentioned in the embodiments of this application refers to a device, component, module, or mechanism capable of driving a structural member to move linearly. The linear drive module can be a linear module, a screw-nut mechanism, a rack-and-pinion mechanism, a pneumatic cylinder, a hydraulic cylinder, etc. The linear drive module mentioned in the embodiments of this application can be any of these, and can be configured and used as needed.

[0093] The linear modules mentioned in the embodiments of this application are also called linear modules, linear slides, etc. Currently, widely used linear modules can be divided into: synchronous belt type, ball screw type, and linear motor type. When the linear drive module mentioned in the embodiments of this application adopts a linear module, it can adopt any of the synchronous belt type linear module, ball screw type linear module, and linear motor type linear module, and can be configured and used according to needs.

[0094] A synchronous belt-type linear module primarily consists of a belt, linear guide, coupling, and motor. The working principle of a synchronous belt-type linear module is as follows: the belt is mounted on drive shafts on both sides of the linear module, one of which serves as the power input shaft and is connected to the motor. A slider, which connects to the workpiece, is fixed to the belt. Rotation of the drive shaft drives the belt, which in turn drives linear movement of the slider.

[0095] Ball screw type linear modules mainly include ball screws, linear guides, ball screw support seats, motors, etc.

[0096] A ball screw converts rotary motion into linear motion, or vice versa. A ball screw primarily consists of a screw and a nut. The screw is a rod-shaped component with an external thread. The nut is a component with an internal thread. The external threads of the screw mate with the internal threads of the nut to allow the nut to be mounted on the screw. Rotation of the screw moves the nut on the screw, converting rotary motion into linear motion. By connecting the workpiece to the nut, linear movement of the nut drives the workpiece. Some ball screws also include balls, which primarily reduce friction between the nut and the screw.

[0097] Linear guides, also known as slides, linear guides, and linear slides, are used in linear reciprocating motion situations. They can bear a certain torque and achieve high-precision linear motion under high load conditions.

[0098] A linear motor module, also known as a linear motor, is a transmission device that converts electrical energy directly into linear motion mechanical energy without the need for any intermediate conversion mechanism.

[0099] The screw-nut mechanism mainly consists of a screw, a nut, and a motor. The nut is mounted on the screw, which is connected to the motor. The motor drives the screw to rotate, pushing the nut on the screw to achieve linear movement. When the nut moves linearly, the workpiece is connected to the nut.

[0100] A rack-and-pinion mechanism primarily consists of a gear, a rack, and a motor. The gear meshes with the rack, which in turn is connected to the motor. The motor drives the gear to rotate, which in turn propels the rack to move linearly. Connecting a workpiece to the rack allows the workpiece to move linearly when the rack moves linearly.

[0101] A cylinder is a mechanical component that guides a piston in linear reciprocating motion within the cylinder. It primarily consists of a barrel, end caps, a piston, a piston rod, and seals. The end caps fit over the ends of the barrel, while the piston rod is connected to the piston. The piston slides within the barrel, extending through the end caps. The seals seal the piston rod and the end caps. High-pressure gas is injected into the barrel on one side of the piston, pushing the piston linearly within the barrel, which in turn pushes the piston rod along the barrel. Connecting a workpiece to the piston rod allows linear movement of the workpiece.

[0102] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and uses it to produce linear reciprocating (or oscillating) motion. A hydraulic cylinder generally consists of a cylinder barrel, a cylinder head, a piston, a piston rod, and a sealing device. The cylinder head covers the end of the cylinder barrel, and the piston rod is connected to the piston. The piston slides into the cylinder barrel and extends through the cylinder head. A seal seals the piston rod and the end cap. This system primarily works by filling the cylinder barrel with high-pressure liquid on one side of the piston, pushing the piston linearly within the barrel, which in turn pushes the piston rod linearly along the barrel. Connecting a workpiece to the piston rod allows linear movement of the workpiece.

[0103] Coating machines are frequently used in industrial production. They are primarily used for surface coating of rolled substrates, such as paper, cloth, leather, aluminum foil, and plastic film. Coatings are made by coating the rolled substrate with a layer of adhesive, paint, or ink with a specific function, drying it, and then cutting it into sheets or rewinding it.

[0104] During the production process of the battery's electrode assembly, a coating machine is often required. For example, the electrode assembly is also called a battery cell, and the electrode assembly consists of a positive electrode sheet, a negative electrode sheet, and a separator. The positive electrode sheet includes a positive electrode current collector and a positive electrode active material layer. The positive electrode active material layer is coated on the surface of the positive electrode current collector. The portion of the positive electrode current collector that is not coated with the positive electrode active material layer protrudes from the portion that is coated with the positive electrode active material layer. The portion that is not coated with the positive electrode active material layer serves as the positive electrode tab, or a metal conductor is welded on the positive electrode current collector and led out to serve as the positive electrode tab. Taking lithium-ion batteries as an example, the material of the positive electrode current collector can be aluminum, and the positive electrode active material can be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide, etc. The negative electrode sheet consists of a negative current collector and a negative active material layer. The negative active material layer is coated on the surface of the negative current collector. The uncoated portion of the negative current collector protrudes from the coated portion. This portion serves as the negative electrode tab, or a metal conductor can be welded to the negative current collector and extended to serve as the negative electrode tab. The negative current collector can be made of copper, and the negative active material can be carbon or silicon. The separator is an insulating film placed between the positive and negative electrodes. Its main function is to separate the positive and negative electrodes, preventing electrons from freely passing through the battery to prevent short circuits, while allowing ions in the electrolyte to pass freely between the positive and negative electrodes, forming a circuit between them. The separator can be made of materials such as PP (polypropylene) or PE (polyethylene). Coating the positive active material layer on the positive current collector, coating the negative active material layer on the negative current collector, and applying the adhesive layer to the separator all require a coating machine.

[0105] When a coater is in use, it must be fed with a rolled substrate (hereafter referred to as the coil). Because coils are generally heavy, a loading device is currently used to load the coil into the coater for use. Before loading, the loading device must support the coil to feed it into the coater and achieve coil loading.

[0106] However, current loading devices are mostly designed to load coils into coating machines. However, installing the coils in the loading device requires manual movement of the coils to the designated position of the loading device, and the coils are supported by the loading device's support shaft. This method of loading the coils into the loading device is inefficient.

[0107] Based on the above considerations, in order to solve the problem of low efficiency when the coil is loaded into the feeding device of the coating machine, an embodiment of the present application provides a coil feeding unit, which is provided with a positioning and feeding mechanism to position the coil and supply it to the support structure so that the support structure can quickly support the coil, thereby improving the efficiency of installing the coil on the coil feeding unit, and further facilitating the coil feeding unit to supply the coil to the coating machine, thereby improving the loading efficiency of the coating machine.

[0108] The coil feeding unit disclosed in the embodiments of the present application can be used to feed coils and thus can be applied to equipment that requires coils, such as a coating machine; it can also be applied to auxiliary feeding equipment for a coating machine, such as a coating machine feeding device; it can also be applied to equipment that cuts and processes coils, such as electrode sheet cutting equipment and electrode assembly winding equipment. In addition, the coil feeding unit disclosed in the embodiments of the present application can also move coils produced by equipment such as a coating machine to a designated location such as a warehouse.
