Description

Technical Field

[0001] The utility model relates to the field of coating machines, in particular to a labeling device. Background Art

[0002] The basic components of a lithium-ion battery include a positive electrode, a negative electrode, an electrolyte, and a separator. During the lithium-ion battery manufacturing process, the positive and negative electrode materials are added to a binder and an organic solvent, stirred and slurried, and then evenly coated onto copper and aluminum foil, which serve as current collectors. After drying, the positive and negative electrodes of the lithium-ion battery are formed. Coating is the most advanced and critical technology in lithium-ion battery production. The uniformity and stability of the electrode coating directly affect the safety and service life of the battery.

[0003] With the expansion of the lithium battery industry, lithium battery manufacturers are demanding that production workshops gradually reduce or even eliminate staff to achieve cost reduction and efficiency improvement. Currently, some lithium battery companies have implemented automatic tape splicing in the roll-to-roll process. This process requires labeling at the end of the roll after the coating machine has finished rewinding. However, existing labeling equipment uses a vacuum suction method combined with a pneumatic cylinder to apply labels, which can easily damage the battery electrodes. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0024] Reference Figures 1 to 2 As shown, the present invention discloses a labeling device. Specifically, the device includes a fixed plate 10, a label unwinding assembly 20, a label rewinding assembly 30, and a rewinding drive assembly 40. The label unwinding assembly 20, the label rewinding assembly 30, and the rewinding drive assembly 40 are all arranged on one side of the mounting plate 10. Accordingly, the label rewinding assembly 30 is used to rewind the release paper after the label is removed; the label unwinding assembly 20 is used to apply labels to the broken edge of the electrode; and the rewinding drive assembly 40 is used to drive the label rewinding assembly 30 to rewind, thereby driving the label unwinding assembly 20 to unwind. In this embodiment, it is necessary to label both ends of the rolled electrode tabs, with a total of six labels applied, to prevent the rewound material from scattering due to its own tension.

[0025] Specifically, the unwinding and labeling assembly 20 includes an unwinding seat 201, a labeling roller 202, a labeling roller 203, a label peeling plate 204, an incoming label sensor 205, and an outgoing label sensor 206. A label roll is mounted on the unwinding seat 201. After being pulled out, the label roll mounted on the unwinding seat 201 passes over the labeling roller 202 and the labeling roller 203. The labeling roller 203 is located at the edge of the fixed plate 10 and is positioned opposite the roll. This relative positioning means that after the labeling device moves a certain distance toward the labeling position of the roll, the labeling roller 203 can precisely press against the roll, that is, the rolling surface of the labeling roller 203 is in contact with the roll. When the labeling roller 203 approaches the roll, the entire labeling device can stop in time, allowing the labeling roller 203 to precisely press against the roll. The labeling roller 202 is located on one side of the stripping plate 204 and between the unwinding seat 201 and the stripping plate 204. It is used to compact and transfer the label roll. A label arrival sensor 205 and a stripping plate 204 are located between the labeling roller 202 and the labeling roller 203. The label arrival sensor 205 and the stripping plate 204 are positioned opposite each other, leaving a gap for the label tape to pass through. After the label roll is pulled out of the unwinding seat 201, it passes through the labeling roller 202 and is bonded to the roller 202. The label roll then passes through the gap between the label arrival sensor 205 and the stripping plate 204 and passes through the labeling roller 203, where it is bonded to the roller 203. A label exit sensor 206 is located next to the labeling roller 203 to detect whether a label has been successfully ejected. The stripping plate 204 is used to peel the label from the label roll.

[0026] The peeling plate 204 has a top and a bottom. The peeling plate 204 is tilted on the fixed plate 10, with the top of the peeling plate 204 positioned below the labeling roller 203. The thickness of the bottom of the peeling plate 204 is greater than the thickness of the top. The thicker bottom of the peeling plate 204 facilitates installation on the fixed plate 204, while the thinner top of the peeling plate 204 facilitates label peeling. The height of the labeling roller on the fixed plate is lower than the height of the peeling plate on the fixed plate, and higher than the height of the release paper roll roller on the fixed plate. This ensures that the peeled label is positioned in front of the labeling roller 203, facilitating label application.

[0027] The label winding assembly 30 includes a winding seat 301, a release paper roll roller 302 and a label missing sensor 303. A label release paper roll is set on the winding seat 301. The label release paper roll passes through the release paper roll roller 302 and the labeling roller 203. A label missing sensor 303 is set on the side of the release paper roll roller 302. The label missing sensor 303 is used to detect whether the label is missing.

[0028] The winding drive assembly 40 includes a labeling winding motor 401, which can drive the winding seat 301 to rewind. In this embodiment, the labeling winding motor 401 drives the rewinding seat 301 to rewind using gears. By providing a gear at the output end of the labeling winding motor 401, and providing gears at one end of the unwinding seat 201 and the rewinding seat 301, when the output end of the labeling winding motor 401 rotates, the gear at the output end of the labeling winding motor 401 engages with the gear of the rewinding seat 301, thereby causing the labeling winding motor 401 to drive the rewinding seat 301 to rewind, thereby causing the unwinding seat 201 to unwind. In other embodiments, a synchronous belt or other method can also be used to enable the labeling winding motor 401 to drive the rewinding seat 301 to rewind, thereby causing the unwinding seat 201 to unwind.

[0029] A micro switch 50 and a damper are also provided on the fixed plate 10. The micro switch 50 is connected to the winding drive assembly 40 for triggering the labeling operation. Figure 3 As shown, the labeling device can be connected to the transverse assembly and the forward assembly (the transverse assembly and the forward assembly are not marked in the figure), the forward assembly is movably connected to the transverse assembly, and the labeling device is movably connected to the forward assembly. The transverse assembly is used to enable the labeling device to move along the width direction of the material roll, and the forward assembly is used to move the labeling device closer to or away from the material roll. In this embodiment, the transverse assembly and the forward assembly use a linear motion module. Since the linear motion module is a technology that is more commonly used by people in this field, the structure of the transverse assembly and the forward assembly will not be introduced. First, the labeling device can move along the width direction of the material roll under the action of the transverse assembly. When the labeling device moves to the position where the label is to be labeled, it will approach the material roll under the action of the forward assembly. At this time, the micro switch 50 will touch the material roll, thereby determining the position of the labeling device. When the micro switch 50 touches the material roll, the labeling device stops moving toward the material roll.

[0030] First, the labeling device is set at the tail position of the material. Under the action of the forward component and the transverse moving component, the labeling device will first move in the width direction of the material roll to the labeling position (at this time, the forward module has not moved, and the micro switch 50 is a distance away from the labeling position of the material roll). Under the action of the labeling rewinding motor 401, the rewinding seat 301 is driven to rewind, and then the unwinding seat 201 is driven to unwind; then the position of the label is detected in advance by the incoming label sensor 205. When the label reaches the peeling plate 204, due to the high hardness of the label itself, it will be peeled off from the release paper. At this time, the label output sensor 205 is used to detect the label position. 06 detects that the label is successfully output, and then stops outputting the label after peeling off a certain length; then the forward component will drive the labeling device to move toward the material roll. When the micro switch 50 touches the material roll, the labeling device stops moving. Because the labeling roller 203 is set at the edge of the fixed plate, the labeling roller 203 can just press on the material roll and stick the peeled part of the label to the tail of the material. Then the coater rewinds, and the labeling device continues to peel off the label and peel off the remaining label. The label is pressed by the labeling roller 203 and the rotation of the material roll to achieve rolling of the label and finally complete the passive labeling.

Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
