Description

Technical Field

[0001] This invention relates to the field of battery recycling technology, and in particular to a degumming device. Background Technology

[0002] During the recycling of power batteries, it is necessary to remove the residual adhesive (hereinafter referred to as residual adhesive) from the battery surface. This is mainly achieved by using an adhesive remover to soften the adhesive on the power battery pack.

[0003] For example, the non-destructive disassembly method for retired power lithium-ion modules disclosed in CN109301372A is mainly used to remove residual adhesive from the surface of lithium-ion batteries. During the adhesive removal process, the battery module to be disassembled is placed in a container filled with adhesive remover and soaked for a period of time to soften the residual adhesive. The softened residual adhesive can then be easily separated from the battery.

[0004] Although existing batteries can easily separate residual adhesive by softening it with adhesive removers, some adhesive still adheres to the battery surface and is difficult to completely separate from the battery through soaking. This means that mechanical separation using separation tools is still required after soaking. Furthermore, the adhesive separated from the battery will mix with the adhesive remover, requiring a separate station to separate the adhesive and adhesive remover after the adhesive is separated for subsequent use of the adhesive remover. Although some existing adhesive removal devices can separate the adhesive and adhesive remover by adding a filter, the separated adhesive can easily clog the filter, so the filter needs to be replaced regularly, which increases the cost of adhesive removal from the battery. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a glue removal device to solve the technical problem that existing glue removal devices are unable to separate the glue remover from the residual glue.

[0006] To achieve the above-mentioned technical objectives, the present invention provides a glue removal device, comprising:

[0007] The container is provided with a glue supply port, a glue outlet, and a continuous bendable glue removal channel. The glue supply port and the glue outlet are respectively connected to the liquid inlet end and the liquid outlet end of the glue removal channel. The glue supply port is used to supply glue remover into the glue removal channel through a glue supply device, and the glue outlet is used for the glue remover to flow out of the glue removal channel.

[0008] A battery fixing module is installed in the adhesive removal channel to fix the battery to be adhesive removed.

[0009] Optionally, the interior of the container is provided with a receiving cavity, a first spacer and a second spacer. The first spacer is fixed to the bottom wall of the receiving cavity, and the second spacer is spaced apart from the first spacer and fixed to the top wall of the receiving cavity. The second spacer and the first spacer separate the container to form the adhesive removal channel.

[0010] Optionally, the adhesive removal device further includes a first stop, which is fixed to the top wall of the receiving cavity and opposite to the first spacer, and a first communication port for the adhesive remover to pass through is formed between the first stop and the first spacer.

[0011] Optionally, the adhesive removal device further includes a second stop, which is fixed to the bottom wall of the receiving cavity and opposite to the second spacer, and a second communication port for the adhesive remover to pass through is formed between the second stop and the second spacer.

[0012] Optionally, the adhesive removal device further includes a blocking module, which is installed on the side wall of the adhesive removal channel to block the flow of residual adhesive.

[0013] Optionally, the blocking module includes a plurality of blocks, each of which is fixed at intervals to the side wall of the adhesive removal channel.

[0014] Optionally, the battery fixing module includes a plurality of clamping members, each of which is connected to the side wall of the adhesive removal channel, and an installation space is formed between adjacent clamping members for mounting the battery to be de-adhesive removed.

[0015] Optionally, each of the clamping members extends in the width direction of the adhesive removal channel to block the flow of residual adhesive in the adhesive removal channel.

[0016] Optionally, the sidewall of the adhesive removal channel is fixed with a sliding rail, and each of the clamping members is slidably connected to the sliding rail.

[0017] Optionally, the adhesive removal device further includes a filter module installed at the adhesive outlet for filtering the adhesive removal agent flowing out of the adhesive outlet.

[0018] Compared with the prior art, the beneficial effects of the adhesive removal device provided by the present invention include: by setting up a container and a battery fixing module, the container is provided with an adhesive supply port, an adhesive outlet, and a continuously bent adhesive removal channel. The adhesive supply port and the adhesive outlet are respectively connected to the liquid inlet and liquid outlet of the adhesive removal channel. The battery fixing module is installed in the adhesive removal channel. During the adhesive removal process, the adhesive supply device is first connected to the adhesive supply port, and then the battery to be removed is installed in the battery fixing module for fixing. The adhesive supply device introduces adhesive remover into the adhesive removal channel through the adhesive supply port. The adhesive remover flows in the adhesive removal channel and contacts the battery. The residual adhesive on the battery is softened by the flowing adhesive remover, which then detaches from the battery, achieving complete separation of the adhesive from the battery. Because the adhesive remover channel has a continuously bent structure, the increased channel length also increases the resistance to the flow of the adhesive, causing heavier adhesive to settle within the channel and preventing it from exiting the outlet with the adhesive remover. Therefore, the adhesive remover device, through the above design, can separate the adhesive from the battery while simultaneously separating the adhesive from the adhesive remover solution.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] Embodiments of the present invention provide a de-adhesive device for separating residual adhesive (residual adhesive) on the surface of a battery from the battery by softening it with a de-adhesive agent, and separating the separated residual adhesive from the de-adhesive agent.

[0032] like Figures 1-4 As shown, the adhesive removal device includes a container 10 and a battery fixing module 20. The container 10 is provided with an adhesive supply port 11, an adhesive outlet 12, and a continuously bent adhesive removal channel 13. The adhesive supply port 11 and the adhesive outlet 12 are respectively connected to the liquid inlet and liquid outlet of the adhesive removal channel 13. The adhesive supply port 11 is used to supply adhesive remover to the adhesive removal channel 13 through a connected adhesive supply device, and the adhesive outlet 12 is used to supply the adhesive remover flowing out of the adhesive removal channel 13. The battery fixing module 20 is installed in the adhesive removal channel 13 and away from the adhesive outlet 12, and is used to fix the battery to be removed.

[0033] Specifically, the adhesive removal device comprises a container 10 and a battery fixing module 20. The container 10 is provided with an adhesive supply port 11, an adhesive outlet 12, and a continuously bent adhesive removal channel 13. The adhesive supply port 11 and the adhesive outlet 12 are respectively connected to the liquid inlet and liquid outlet of the adhesive removal channel 13. The battery fixing module 20 is installed in the adhesive removal channel 13. During the adhesive removal process, the adhesive supply device is first connected to the adhesive supply port 11, and then the battery to be removed is installed in the battery fixing module 20 for fixing. The adhesive supply device supplies adhesive remover to the adhesive supply port 11. The adhesive remover enters the liquid inlet of the adhesive removal channel 13 and then flows along the extension direction of the adhesive removal channel 13. Figure 3 The adhesive flows in the direction of the middle arrow, entering the outlet of the adhesive removal channel 13 and finally flowing out from the adhesive outlet 12. During the flow of the adhesive removal channel 13, the adhesive remover immerses the battery in the adhesive removal channel 13 and contacts the residual adhesive on the battery, softening the residual adhesive. Since the adhesive remover is always in a flowing state, the softened residual adhesive is carried away from the battery by the flowing adhesive remover, realizing the complete separation of residual adhesive from the battery. Moreover, since the adhesive removal channel 13 has a continuously bent serpentine structure, the continuously bent structure of the adhesive removal channel 13 can increase the channel length and also increase the resistance when the residual adhesive flows, so that the denser residual adhesive settles in the adhesive removal channel 13 and will not flow out from the adhesive outlet 12 with the adhesive remover, thus realizing the separation of residual adhesive from adhesive remover. Therefore, by setting the adhesive removal channel 13 of the adhesive removal device, the residual adhesive can be separated from the battery at the same time as the residual adhesive and the adhesive removal liquid.

[0034] Understandably, the container 10 can be a top-opening groove, a sealed box, or other structures. When the container 10 is a top-opening groove, it can be placed horizontally during battery degumming. In this case, the degumming channel 13 is a guide channel that opens at the top and bends horizontally. The degumming agent flows out from the outlet 12 under the guidance of the guide channel. In this state, the depth of the degumming channel 13 should be greater than the height of the battery so that the degumming agent can completely submerge the battery. When the container 10 is a sealed box, it can be placed horizontally or vertically during battery degumming, as long as the degumming agent can enter from the supply port 11 and flow out from the outlet 12.

[0035] In this embodiment, the container 10 is also provided with a residual adhesive outlet (not shown in the figure). The residual adhesive outlet is connected to the liquid outlet of the adhesive removal channel 13. When the residual adhesive accumulated at the residual adhesive outlet reaches a certain amount, the residual adhesive can be cleaned through the residual adhesive outlet.

[0036] In one embodiment, such as Figures 3-4 As shown, the interior of the container 10 is provided with a receiving cavity 14, a first spacer 15 and a second spacer 16. The first spacer 15 is fixed to the bottom wall of the receiving cavity 14, and the second spacer 16 is spaced apart from the first spacer 15 and fixed to the top wall of the receiving cavity 14. The second spacer 16 and the first spacer 15 separate the container 10 to form a de-adhesive flow channel 13. The battery fixing module 20 is installed on the first spacer 15.

[0037] Specifically, the first spacer 15 and the second spacer 16 divide the receiving cavity 14 into a continuously bent serpentine flow channel. By setting the receiving cavity 14, the degumming flow channel 13 can form a closed flow space. Thus, during the degumming process of the battery, the receiving body 10 can be placed vertically, so that the degumming flow channel 13 can be bent and extended in the vertical direction, thereby allowing the degumming agent to fill the degumming flow channel 13, fully immersing the battery, ensuring the quality of battery degumming, and facilitating the settling of residual glue on the degumming agent, making it difficult for residual glue to flow along the degumming flow channel 13 towards the glue outlet 12 under the action of the degumming agent.

[0038] Understandably, the number of the first spacer 15 and the second spacer 16 can be adaptively set according to factors such as the flow rate of the desiccant, the volume of the battery, and the number of batteries in the desiccant flow channel 13.

[0039] In this embodiment, as Figures 3-4As shown, taking the arrangement of three first spacers 15 and two second spacers 16 as an example, the three first spacers 15 are spaced apart, and the lower ends of the three first spacers 15 are all fixed to the bottom wall of the receiving cavity 14. The upper ends of the three first spacers 15 extend toward the top wall of the receiving cavity 14. The two second spacers 16 are staggered with the three second spacers 16, and the upper ends of the two second spacers 16 are fixed to the top wall of the receiving cavity 14.

[0040] Understandably, the first spacer 15 and the second spacer 16 can be any shape, such as block or column, that can divide the receiving cavity 14 into flow channels.

[0041] Understandably, the side of the first spacer 15 forms the sidewall of the adhesive removal channel 13, and the battery fixing module 20 can be installed on the first spacer 15 and / or the second spacer 16.

[0042] In one embodiment, such as Figure 3 As shown, the adhesive remover flowing through the battery fixing module 20 flows upwards. This design allows the battery fixing module 20 to block the upward-flowing residual adhesive, facilitating its settling.

[0043] In one embodiment, such as Figure 3 As shown, the battery fixing module 20 is installed on the side of the first spacer 15 near the glue supply port 11, and the glue outlet 12 is located on the side of the first spacer 15 away from the battery fixing module 20.

[0044] Specifically, this setting allows the adhesive remover flowing through the battery fixing module 20 to flow upwards, thereby enabling the battery fixing module 20 to block the upward-flowing residual adhesive. The adhesive outlet 12 is positioned on the side of the first spacer 15 away from the battery fixing module 20, allowing the adhesive outlet 12 to be positioned away from the battery fixing module 20. This allows the residual adhesive that has been separated to settle before being discharged from the adhesive outlet 12.

[0045] Understandably, the battery fixing module 20 can be any structure that can fix the battery, such as a slot or fixing rod.

[0046] In one embodiment, such as Figures 3-4 As shown, the battery fixing module 20 includes several clamping members 21, each of which is connected to the side wall of the adhesive removal channel 13. An installation space 22 is formed between adjacent clamping members 21, providing space for mounting the battery to be de-adhesive-removed. Specifically, when installing the battery, simply place it in the installation space 22. The clamping action of the clamping members 21 not only secures the battery but also exposes any residual adhesive on the battery to the adhesive remover, facilitating its removal.

[0047] Understandably, the clamping member 21 can be connected to the adhesive removal channel 13 in a fixed connection, sliding connection, or other forms.

[0048] In one embodiment, such as Figures 3-4 As shown, each clamping member 21 extends in the width direction of the adhesive removal channel 13 to block the flow of residual adhesive in the adhesive removal channel 13. Specifically, since the clamping member 21 extends in the width direction of the adhesive removal channel 13, the area of ​​the clamping member 21 can be effectively increased, thereby enabling the clamping member 21 to effectively block the flow of residual adhesive, promote the sedimentation of residual adhesive, and facilitate the separation of residual adhesive from adhesive remover.

[0049] In one embodiment, such as Figures 3-4 As shown, a sliding rail 151 is fixed to the side wall of the degumming channel 13, and each clamping member 21 is slidably connected to the sliding rail 151. Specifically, through the sliding connection between the clamping member 21 and the sliding rail 151, the size of the installation space 22 can be adjusted by sliding the clamping member 21, thereby accommodating the installation of batteries of different sizes and expanding the applicability of the degumming device.

[0050] In one embodiment, such as Figures 3-4 As shown, the adhesive removal device also includes a first baffle 30, which is fixed to the top wall of the receiving cavity 14 and opposite to the first spacer 15. A first connecting port 31 for the adhesive remover to pass through is formed between the first baffle 30 and the first spacer 15. Specifically, the first connecting port 31 allows the adhesive remover to pass through the first spacer 15, facilitating the flow of the adhesive remover within the adhesive removal channel 13. When the adhesive remover overflows the first spacer 15, it will rise further to the first baffle 30. The first baffle 30 can block the flowing residual adhesive, thereby preventing the residual adhesive from flowing further with the adhesive remover, while promoting the sedimentation of the residual adhesive and improving the separation quality of the residual adhesive and the adhesive remover liquid.

[0051] In one embodiment, such as Figures 3-4 As shown, the adhesive removal device also includes a second baffle 40, which is fixed to the bottom wall of the receiving cavity 14 and opposite to the second spacer 16. A second connecting port 41 for the adhesive remover to pass through is formed between the second baffle 40 and the second spacer 16. Specifically, the second connecting port 41 allows the adhesive remover to pass through the second spacer 16, facilitating the flow of the adhesive remover within the adhesive removal channel 13. The second baffle 40 can block the flowing residual adhesive, thereby preventing the residual adhesive from flowing further with the adhesive remover, while promoting the sedimentation of the residual adhesive and improving the separation quality of the residual adhesive and the adhesive remover liquid.

[0052] In one embodiment, such as Figures 3-4As shown, the adhesive removal device also includes a blocking module 50, which is installed on the side wall of the adhesive removal channel 13 to block the flow of residual adhesive. Specifically, when the residual adhesive flowing with the adhesive remover comes into contact with the blocking module 50, it will flow further under the obstruction of the blocking module 50, thereby promoting the separation of residual adhesive and adhesive remover.

[0053] Understandably, the blocking module 50 can be installed on the top wall, side wall or bottom wall of the adhesive removal channel 13, and the blocking module 50 can be a baffle, filter or other structure that can block the flow of residual adhesive.

[0054] In one embodiment, such as Figures 3-4 As shown, the blocking module 50 includes several baffles 51, each baffle 51 being fixed at intervals to the side wall of the adhesive removal channel 13. Specifically, by setting the blocking module 50 to several baffles 51 spaced apart, the blocking module 50 can effectively block the flow of residual adhesive without affecting the flow of adhesive remover, and can prevent residual adhesive from clogging the blocking module 50.

[0055] In one embodiment, such as Figures 3-4 As shown, each baffle 51 is fixed to the bottom wall of the adhesive removal channel 13. Since a large amount of residual adhesive has settled on the bottom wall of the adhesive removal channel 13, this residual adhesive will not flow with the adhesive remover due to the obstruction of the baffle 51.

[0056] In one embodiment, because some of the residual adhesive is fine and lightweight, it is difficult for this portion to settle within the adhesive removal channel 13. Instead, it flows with the adhesive remover into the outlet of the adhesive removal channel 13. To prevent this portion of the residual adhesive from flowing out of the outlet 12 with the adhesive remover, such as... Figure 3 As shown, the adhesive removal device also includes a filter module 60, which is installed at the adhesive outlet 12 and is used to filter the adhesive removal agent flowing out of the adhesive outlet 12. Specifically, the filter module 60 can block small particles of residual adhesive flowing out of the adhesive outlet 12, thereby preventing residual adhesive from flowing out of the adhesive outlet 12 with the adhesive removal agent. Since the amount of residual adhesive entering the liquid outlet of the adhesive removal channel 13 is small, it will not cause blockage to the adhesive outlet 12 and the filter module 60.

[0057] The specific working principle of the adhesive removal device provided in the embodiments of the present invention is as follows: When removing adhesive from the battery, the adhesive removal device is placed vertically, and the installation gap is adjusted according to the size of the battery. Then, the battery is placed between the clamping parts 21 for installation. Then, the adhesive supply device is connected to the adhesive supply port 11, and the adhesive supply device introduces adhesive remover into the liquid inlet of the adhesive removal channel 13 through the adhesive supply port 11. The adhesive remover flows along the extension direction of the adhesive removal channel 13 and finally enters the liquid outlet of the adhesive removal channel 13. The adhesive then flows out from the outlet 12. The adhesive remover in the adhesive removal channel 13 submerges the battery, softening the residual adhesive. The adhesive then detaches from the battery due to the flow. The detached residual adhesive settles in the adhesive removal channel 13 under the resistance of the channel, the obstruction of the clamping member 21, the stop block 51, the first stop member 30 and the second stop member 40, and its own gravity. This prevents the adhesive from entering the outlet of the adhesive removal channel 13 along with the adhesive remover, thus separating the residual adhesive from the adhesive remover and facilitating the subsequent processing of the adhesive remover.

[0058] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
