In the production of batteries, it is often necessary to affix a gummed paper to some component of the battery (e.g., an electrode assembly); in some cases, it is necessary to apply the gummed paper to two surfaces with a height difference, which puts higher demands on the gumming device.

For example, in the production process of a battery, it is necessary to paste a jelly-roll on an electrode assembly.

Specifically, the electrode assembly includes a positive electrode, a negative electrode, and a separator. During the charge and discharge of the battery cell, active ions (e.g., lithium ions) are inserted and extracted back and forth between the positive electrode and the negative electrode. The separator is arranged between the positive electrode and the negative electrode, can play a role in preventing the positive electrode and the negative electrode from being short-circuited, and can enable active ions to pass through.

The electrode assembly generally includes a cell body and tabs extending from the cell body, the tabs being operable to conduct current generated by the cell body. The tab generally needs to be welded to the electrode terminal or the switching tab; after the welding is completed, it is generally necessary to paste an adhesive paper on the tab to cover the welding marks on the tab. In order to improve the adhesive strength of the adhesive tape and reduce the risk of the adhesive tape falling off, it is generally necessary to adhere the adhesive tape to the outer surface of the cell body.

The outer surface of the battery cell main body and the electrode lugs have height difference, and how to paste the gummed paper to the battery cell main body and the electrode lugs at the same time is a problem to be solved urgently.

In view of this, the embodiment of the application provides a rubberizing device, and rubberizing device includes first rubberizing mechanism, second rubberizing mechanism and stop gear. The second rubberizing mechanism is movably connected with the first rubberizing mechanism along the first direction. The limiting mechanism is connected to the first rubberizing mechanism and the second rubberizing mechanism. The limiting mechanism is used for limiting the relative movement of the second rubberizing mechanism and the first rubberizing mechanism in the first direction. The limiting mechanism is configured to release the restriction of the relative movement of the second rubberizing mechanism and the first rubberizing mechanism in the first direction if the force in the first direction to which the limiting mechanism is subjected reaches a threshold value.

The first rubberizing mechanism and the second rubberizing mechanism are arranged to be capable of relatively moving, and can respectively press the gummed paper on two different positions of the part to be rubberized. In the process that the second rubberizing mechanism and the first rubberizing mechanism drive the gummed paper to synchronously move towards the part to be rubberized, the limiting mechanism can limit the relative movement of the second rubberizing mechanism and the first rubberizing mechanism, and the offset of the gummed paper in the movement process is reduced. In the rubberizing process, the limit mechanism can release the limit of the limit mechanism to the second rubberizing mechanism and the first rubberizing mechanism according to the pressure, so that the pressure to which the parts to be rubberized are subjected is controlled, and the risk that the parts to be rubberized are crushed is reduced.

The rubberizing device provided by the embodiment of the application is not limited to be used in the field of batteries, and can be used in other fields.

The rubberizing device provided by the embodiment of the application not only can be used for rubberizing the electrode assembly, but also can be used for rubberizing other parts of the battery.

The following describes the rubberizing device of the embodiment of the application in detail with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of a rubberizing device according to some embodiments of the present application; FIG. 2 is a schematic diagram of the rubberizing device shown in FIG. 1 during rubberizing; FIG. 3 is another schematic view of the rubberizing device shown in FIG. 1 during rubberizing; fig. 4 is a further schematic view of the rubberizing device shown in fig. 1 during rubberizing.

Referring to fig. 1 to 4, the rubberizing device of the embodiment of the application may include a first rubberizing mechanism 1, a second rubberizing mechanism 2, and a limiting mechanism 3. The second rubberizing mechanism 2 is movably connected to the first rubberizing mechanism 1 along a first direction Z. The limiting mechanism 3 is connected to the first rubberizing mechanism 1 and the second rubberizing mechanism 2. The limiting mechanism 3 is used for limiting the relative movement of the second rubberizing mechanism 2 and the first rubberizing mechanism 1 in the first direction Z.

The limiting mechanism 3 is configured to release the restriction of the relative movement of the second rubberizing mechanism 2 and the first rubberizing mechanism 1 in the first direction Z in case the force in the first direction Z to which the limiting mechanism 3 is subjected reaches a threshold value.

The second rubberizing mechanism 2 may be directly movably connected to the first rubberizing mechanism 1 or may be movably connected to the first rubberizing mechanism 1 by other means.

The limiting mechanism 3 may be an integral part or may comprise a plurality of parts connected to each other.

The limiting mechanism 3 may be a mechanism that is actuated to release the limitation of the relative movement of the second rubberizing mechanism 2 and the first rubberizing mechanism 1 in the first direction Z in case the applied force in the first direction Z reaches a threshold value

The actual threshold will vary depending on design requirements. For example, the threshold may depend on the type of component to be rubberized, the degree of withstand voltage of the component to be rubberized, the type of gummed paper, or other factors.

The spacing mechanism 3 is a force-actuated component. Forms of actuation of the spacing mechanism 3 include, but are not limited to: fracture, component separation, failure of the connection of the limiting mechanism 3 to the first rubberizing mechanism 1, failure of the connection of the limiting mechanism 3 to the second rubberizing mechanism 2, etc.

After the parts to be rubberized are in place, the first rubberizing mechanism 1 and the second rubberizing mechanism 2 drive the gummed paper P to move along the first direction Z so as to gradually approach the parts to be rubberized. The limiting mechanism 3 limits the relative movement of the second rubberizing mechanism 2 and the first rubberizing mechanism 1 during the approach to the parts to be rubberized, thereby reducing the offset of the gummed paper P during the movement.

As shown in fig. 3, the first rubberizing mechanism 1 continues to move in the first direction Z while the second rubberizing mechanism 2 presses the gummed paper P to a to-be-rubberized position of a part to be rubberized; with the movement of the first rubberizing mechanism 1, the pressure applied by the second rubberizing mechanism 2 to the gummed paper P gradually increases under the limit of the limit mechanism 3, thereby adhering the gummed paper P to the part to be rubberized.

As the pressure applied to the gummed paper P by the second gumming mechanism 2 increases, the reaction force received by the second gumming mechanism 2 also increases gradually, and correspondingly, the force received by the limiting mechanism 3 in the first direction Z also increases gradually. Under the condition that the acting force of the limiting mechanism 3 in the first direction Z reaches a threshold value, the limiting mechanism 3 releases the limitation of the relative movement of the second rubberizing mechanism 2 and the first rubberizing mechanism 1 in the first direction Z, so that when the first rubberizing mechanism 1 continues to move in the first direction Z, the pressure applied by the second rubberizing mechanism 2 to the gummed paper P cannot be further increased, and the risk of the rubberized part to be rubberized being crushed is reduced.

After the limiting mechanism 3 releases the restriction of the relative movement of the second rubberizing mechanism 2 and the first rubberizing mechanism 1 in the first direction Z, the first rubberizing mechanism 1 may continue to move until the gummed paper P is pressed to another rubberizing position of the components to be rubberized, as shown in fig. 4.

In summary, in the embodiment of the present application, the first rubberizing mechanism 1 and the second rubberizing mechanism 2 are disposed to be relatively movable, and can respectively press the gummed paper P on two different positions of the component to be rubberized. In the process that the second rubberizing mechanism 2 and the first rubberizing mechanism 1 drive the gummed paper P to synchronously move towards the parts to be rubberized, the limiting mechanism 3 can limit the relative movement of the second rubberizing mechanism 2 and the first rubberizing mechanism 1, and the offset of the gummed paper P in the movement process is reduced. In the rubberizing process, the limit mechanism 3 can release the limit of the limit mechanism to the second rubberizing mechanism 2 and the first rubberizing mechanism 1 according to the pressure, so that the pressure to which the parts to be rubberized are subjected is controlled, the risk that the parts to be rubberized are crushed is reduced, the yield is improved, and the rubberizing quality is improved.

Compared with the scheme of connecting the second rubberizing mechanism and the first rubberizing mechanism by utilizing elastic components such as springs, the embodiment of the application can better control the pressure of the components to be rubberized. Specifically, if the second rubberizing mechanism is connected with the first rubberizing mechanism by using a spring, after the second rubberizing mechanism presses the gummed paper to a rubberizing position of a component to be rubberized, the spring is continuously compressed along with the continuous movement of the first rubberizing mechanism, so that the pressure of the component to be rubberized by the second rubberizing mechanism is continuously increased, and the risk of the component to be rubberized being crushed is caused. The limiting mechanism 3 of the embodiment of the application can release the limitation of the limiting mechanism on the second rubberizing mechanism 2 and the first rubberizing mechanism 1 according to the pressure, so that the pressure to which the rubberizing part is subjected is controlled, and the risk that the rubberizing part is crushed is reduced.

In some embodiments, the first direction Z is parallel to the direction of gravity. After the limiting mechanism 3 is actuated, the second rubberizing mechanism 2 can be pressed on the gummed paper P under the action of gravity, so that the elastic shrinkage of the gummed paper P is reduced, and the rubberizing quality is improved.

In some embodiments, a rubberizing device may be used to paste the gummed paper P to the electrode assembly 4.

In some embodiments, the first adhesive tape mechanism 1 is used to adhere the adhesive tape P to the tab 42, and the second adhesive tape mechanism 2 is used to adhere the adhesive tape P to the surface of the cell body 41 of the electrode assembly 4.

The limiting mechanism 3 of the embodiment of the application can release the limitation of the limiting mechanism 3 to the second rubberizing mechanism 2 and the first rubberizing mechanism 1 according to the pressure, so that the pressure born by the battery cell main body 41 is controlled, and the risk of pole piece cracking of the battery cell main body 41 and the risk of pole lug 42 cracking are reduced.

In some embodiments, after welding the tab 42 of the electrode assembly 4 to the tab 5, the gummed paper P is stuck using a gumming device. In the battery, the tab 5 is used to connect the tab 42 with an electrode terminal of the battery.

In some embodiments, the limiting mechanism 3 includes a first limiting member 31 and a second limiting member 32 disposed along the first direction Z, the first limiting member 31 is fixed to the first rubberizing mechanism 1, the second limiting member 32 is fixed to the second rubberizing mechanism 2, and the first limiting member 31 and the second limiting member 32 are detachably connected.

The connection manner of the first limiting member 31 and the second limiting member 32 includes, but is not limited to, clamping connection, magnetic connection, vacuum connection or other connection manners.

In case the applied force in the first direction Z reaches a threshold value, the connection between the first and second limiting members 31, 32 fails, and the first and second limiting members 31, 32 may be separated in the first direction Z, thereby releasing the restriction of the relative movement of the second rubberizing mechanism 2 and the first rubberizing mechanism 1 in the first direction Z. After the rubberizing is finished, the first limiting piece 31 and the second limiting piece 32 can be connected again, in other words, the limiting mechanism 3 can be reused, and therefore cost is saved.

In some embodiments, after the rubberizing is completed, the first rubberizing mechanism 1 is moved in a direction away from the part to be rubberized; when the first rubberizing mechanism 1 is moved to a certain position, the first limiting member 31 and the second limiting member 32 can be reconnected.

In some embodiments, one of the first stopper 31 and the second stopper 32 is a magnet having magnetism, the other is a magnet having magnetism or a structure including a magnetic material, and the first stopper 31 and the second stopper 32 are configured to be fixed by magnetic attraction.

Magnets can generate a magnetic field to attract or repel some substances. Illustratively, the magnets include, but are not limited to, magnets, magnetites, and the like. Alternatively, the magnet is a strong rubidium magnet.

The magnetic material is able to react in some way to the magnetic field. Magnetic materials include, but are not limited to, iron, nickel, cobalt, alloys thereof, and the like.

The first limiting piece 31 and the second limiting piece 32 are configured to be attracted and fixed through magnetic force, and the structure of the first limiting piece 31 and the second limiting piece is not easy to damage when the first limiting piece and the second limiting piece are separated under the action of external force; after the rubberizing is completed, the first limiting piece 31 and the second limiting piece 32 can be automatically connected under the action of magnetic force, so that the process can be simplified, the labor is reduced, and the rubberizing efficiency is improved.

During the rubberizing process, the threshold value is related to the magnetic attraction force between the first stop 31 and the second stop 32. The embodiment of the application can set the magnetic adsorption force between the first limiting piece 31 and the second limiting piece 32 according to the pressure bearing capacity of the to-be-glued component.

In some embodiments, the first limiting member 31 is a magnet, such as a rubidium magnet. The second limiting member 32 is a magnetically attracted member, for example, the second limiting member 32 may be an iron pillar.

In some embodiments, after the rubberizing is completed, the first rubberizing mechanism 1 moves upwards; the first stopper 31 and the second stopper 32 are gradually brought close to each other and are attached by magnetic attraction.
