Description

Technical Field

[0001] The utility model relates to the technical field of battery recycling, and specifically provides a glue removal device and battery disassembly equipment. Background Art

[0002] With the advancement of technology and the economy, lithium batteries are increasingly being used, especially in new energy vehicles. Battery packs use structural adhesive to bond the cell to the casing, making it difficult to remove during recycling. Existing methods for removing the adhesive require manual disassembly at room temperature, which is inefficient, energy-intensive, costly, and prone to damage to the cell.

[0003] In order to solve the above technical problems, the following methods can be used to remove the structural adhesive. First, the low-temperature freezing method is used to remove the structural adhesive, but the low-temperature freezing method has high energy consumption and the adhesive removal is not thorough. Second, the sol chemical method is used for removal. The use of the sol requires a long time of infiltration, and it is difficult to remove the adhesive if the infiltration is not thorough, resulting in poor adhesive removal effect. Third, ultrasonic vibration is used to remove the adhesive, but ultrasonic vibration will produce ripples that can easily damage the inside of the battery cell. In summary, the various existing adhesive removal methods are either inefficient, have poor adhesive removal effects, or are prone to damage to the battery cell.

[0004] Therefore, the relevant field urgently needs a degumming device and battery disassembly equipment to solve the above technical problems. Utility Model Content

[0025] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0026] It should be noted that in the description of this utility model, terms such as "upper," "lower," "left," "right," "inner," and "outer" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or component described must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, it should not be understood as limiting the utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance.

[0027] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "installed," "set," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0028] Various existing degumming methods are either inefficient, have poor degumming effects, or are prone to damage to the battery cells. To address the above technical issues, this embodiment discloses a battery disassembly device, which includes a degumming device, a transfer device, and a removal device. The transfer device transfers the battery cells after upstream mechanical disassembly to the degumming device, which then degummes the battery cells. After degumming is completed, the removal device removes the degummed battery cells for the next process.

[0029] Among them, such as Figure 1 and 2As shown, the degumming device includes a placement table, wherein the battery cell 1 is placed on the placement table, and a fixing mechanism is provided on the placement table, wherein the fixing mechanism includes two fixed plates arranged at right angles and two movable plates arranged at right angles, and the movable plates are arranged at the output end of the linear drive component. After the battery cell 1 is placed on the placement table, the two adjacent sides of the battery cell 1 are respectively aligned with the two fixed plates. Then the two linear drives respectively drive the movable plates to approach the other two sides of the battery cell 1, and the movable plates and the fixed plates cooperate with each other to clamp the battery cell 1 for heating and degumming. By fixing the battery cell 1 with the fixing mechanism, the battery cell 1 can be placed in the same position on the placement table each time, and the accuracy of degumming can be guaranteed. The linear drive component can specifically be an electric push rod, or a linear drive mechanism such as a cylinder.

[0030] Regarding the fixing mechanism, it should be noted that although the present embodiment includes two movable plates, both of which are connected to linear drive members, this is not a limitation of the present invention. Without departing from the principles of the present invention, other embodiments may include two movable plates arranged at right angles and fixedly connected, with an inclined linear drive member disposed on the movable plate, which drives the movable plates toward the battery to cooperate with the fixed plate to fix the battery cell 1. The movable plates' movement trajectory is the diagonal of the battery cell 1, and the battery cell 1 is fixed by fixing the two opposite corners of the battery cell 1. Alternatively, the two fixed plates may be located at an angle at one end of the battery cell 1, and two movable plates fixedly connected and arranged at an angle are located at the other end of the battery cell 1, with the linear drive members connected to the movable plates. The linear drive member drives the movable plates to move, so that the movable plates and the fixed plates cooperate to clamp the two ends of the battery to fix the battery cell 1. These embodiments do not depart from the basic principles of the present invention and fall within the scope of protection of the present invention.

[0031] The degumming device also includes a heating mechanism and a degumming mechanism. Among them, the heating mechanism includes a heating element 3 and a linear drive element, wherein the heating element 3 is provided with a heating surface, and the heating surface is specifically the lower surface of the heating element 3. The heating surface can be attached to the glue layer 2 of the battery cell 1 to heat the glue layer 2 of the battery cell 1. The heating surface is a plane, which can be attached to the upper surface of the battery cell 1, and can evenly heat the surface of the battery cell 1, so that all positions of the glue layer 2 can be heated to facilitate degumming. The output end of the linear drive element is connected to the heating element 3, and the linear drive element is used to drive the heating element to be attached to the battery cell 1 to heat the battery cell 1. In this embodiment, the linear drive element is specifically an electric push rod. In other embodiments, it can also be a linear drive mechanism such as a cylinder.

[0032] The heating mechanism is located above the battery core 1 , and the linear driving member drives the heating member 3 downward so that the heating member 3 is attached to the battery core 1 to heat the adhesive layer 2 of the battery core 1 .

[0033] A heating core is provided in the heating element 3, wherein there are multiple heating cores, which are arranged side by side in the heating element 3. The heating core is specifically an electric heating core, which heats the heating element 3 so that the heating element 3 heats the battery core 1.

[0034] The heating element 3 briefly heats the battery cell 1, and only needs to heat the glue layer 2 to facilitate glue removal. The heating temperature of the heating element 3 is 120℃-250℃, and preferably 150℃ in this embodiment. The heating time of the heating element 3 on the battery cell 1 is 15s-60s, and preferably 20s in this embodiment. Since the heating time is short and the glue removal is carried out when the battery cell 1 is powered off or out of power, only the temperature of the battery cell 1 on which the glue is removed will be higher, and the temperature of other positions of the battery cell 1 will not increase, which can ensure the safety of the battery. In addition, the glue removal is completed in a short time, and the side with higher temperature will be transferred to other positions of the battery cell 1, so that the position with higher temperature of the battery cell 1 can be quickly reduced, which can further ensure the safety of the battery cell 1.

[0035] Regarding the heating temperature and heating time, it should be noted that although 150°C for 20 seconds is selected in this embodiment, this is not a limitation of the present invention. Without departing from the principles of the present invention, in other embodiments, those skilled in the art may choose to heat at 200°C for 18 seconds. The principle is that the heating time is inversely proportional to the heating temperature, that is, the longer the heating time, the lower the heating temperature; the shorter the heating time, the higher the heating temperature. It is only necessary to reduce the adhesion of the adhesive layer 2 to facilitate debonding. This does not deviate from the basic principles of the present invention and will fall within the scope of protection of the present invention.

[0036] The adhesive removal mechanism includes an adhesive removal driving member and an adhesive removal member 4 arranged at an output end of the adhesive removal driving member. The adhesive removal driving member drives the adhesive removal member 4 to move so that the adhesive removal member 4 removes the heated adhesive layer 2.

[0037] The degumming device also includes a flipping mechanism, which includes a flipping drive component and a clamping component arranged at the output end of the flipping drive component, the clamping component is used to clamp the battery cell 1, and the flipping drive component is used to drive the clamping component to flip, so that the battery cell 1 is flipped to remove the glue layer 2 on the other side of the battery cell 1. Before the flipping mechanism flips the battery cell 1, it is necessary to release the fixation of the battery cell 1 by the fixing mechanism, and after the battery cell 1 is flipped, it is necessary to use the fixing mechanism to fix the battery cell 1 again. The clamping component is specifically an ordinary clamping claw, which only needs to be able to clamp the battery cell 1, and the specific structure will not be repeated here. The flipping drive component specifically includes a flipping bracket and a servo motor, the clamping component is rotatably arranged on the flipping bracket, the servo motor is arranged on the flipping bracket, and is transmission-connected to the clamping component. The servo motor can drive the clamping component to rotate, and after rotation, it is locked by the servo motor so that the clamping component cannot rotate.

[0038] In addition, in order to enable the battery cell 1 to be flipped smoothly, and after flipping, the flipping mechanism will not interfere with the degumming mechanism. The flipping mechanism also includes a vertical drive member and a horizontal drive mechanism, wherein the output end of the horizontal drive mechanism is connected to the flipping bracket, and the horizontal drive mechanism specifically includes a horizontal electric push rod and a horizontal bracket, and the flipping bracket is slidably arranged on the horizontal bracket, and the horizontal electric push rod is fixed on the horizontal bracket, and the flipping bracket is pushed forward and backward by the horizontal electric push rod. In addition, the vertical drive member includes a vertical bracket and a vertical electric push rod, and the horizontal bracket is vertically slidably arranged on the vertical bracket, and the vertical electric push rod is connected to the horizontal bracket, and the horizontal bracket is driven to move up and down by the vertical electric push rod. When the battery cell 1 needs to be flipped, the horizontal electric push rod pushes the clamping assembly and the flipping bracket forward so that the clamping assembly clamps the battery cell 1. Then the vertical electric push rod pushes the horizontal bracket upward so that the clamping assembly moves upward with the battery cell 1, so that the flipping drive assembly drives the clamping assembly to rotate and drives the battery cell 1 to flip. After the flipping is completed, the horizontal support is driven downward by the vertical electric push rod to place the battery cell 1 on the placement table again for heating and debonding operations.

[0039] Although in the present embodiment, the flipping mechanism can flip the battery cell 1 180°, this is not a limitation of the present invention. Without departing from the principle of the present invention, in other embodiments, the flipping mechanism does not include a horizontal drive member and a vertical drive member, but includes two or three swing arms. The swing arms can be used to swing the clamp in various directions, and cooperate with the flipping drive assembly to flip the battery cell 1, so that the battery cell 1 can be flipped in various directions, so that all sides of the battery cell 1 can face upward, so as to remove the glue from the surface of the battery cell 1 with the glue layer 2.

[0040] The adhesive stripping unit 4 includes a clamping jaw capable of gripping the adhesive layer 2 on the heating surface. A linear actuator is provided to drive the clamping jaw to one side, thereby removing the adhesive layer 2. The clamping jaw is positioned at the output end of the actuator. Before adhesive stripping, the actuator drives the clamping jaw to one end of the battery cell 1, where it begins gripping the adhesive layer 2. The actuator then retracts the clamping jaw toward the other end of the battery cell 1, removing the adhesive layer 2 and ultimately removing it.

[0041] Although the present embodiment adopts a linear motion tearing method for tearing, this is not a limitation of the present invention. Without departing from the principle of the present invention, in other embodiments, those skilled in the art may also choose to tear off the adhesive layer 2 by a curling tearing method. Specifically, the adhesive removal member 4 includes a clamping claw, which can clamp the adhesive layer 2 on the heating surface, and a adhesive removal driving member can drive the clamping claw to rotate and drive the clamping claw to move to one side to curl and tear off the adhesive layer 2. The adhesive removal driving member includes a rotating driving member and a linear driving member, the clamping claw is arranged at the output end of the rotating driving member, and the rotating driving member is arranged at the output end of the linear driving member. Before adhesive removal, the adhesive removal driving member drives the rotating driving member to move to one end of the battery cell 1, and the clamping claw clamps the adhesive layer 2 at the beginning; then the rotating driving member drives the clamping claw to rotate to curl and tear off the adhesive; at the same time, the linear driving member drives the rotating driving member to retract, so that the clamping claw moves to the other end of the battery cell 1 to achieve curling and tearing off the adhesive. All of this does not deviate from the basic principle of the present invention and will fall within the scope of protection of the present invention.

[0042] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
