The CTP battery pack simplifies the manufacturing process of the traditional battery pack from the cell → module → whole pack into the cell → whole pack, removes the intermediate state of the module, and fixes the cell on the cold plate through the structural adhesive and applies the pre-tightening force interference fit to the cell through the structural frame. The CTP battery pack discards the traditional end plate and bolt locking, saves parts, reduces the weight of the whole pack, improves the volume utilization and energy density of the battery pack, and is beneficial to improving the endurance of the electric vehicle. However, due to the presence of the structural adhesive, the recycling of the CTP battery pack becomes more difficult.

[0003] The related art uses a method of low-temperature freezing, sol agent or ultrasonic vibration to remove the structural adhesive. However, the low-temperature freezing needs a long time of freezing treatment, and requires personnel to work continuously in the environment of 0℃ to -40℃, which has high energy consumption, low disassembling efficiency, and high requirements for the equipment of the site personnel, and the disassembling cost and capacity cannot be applied to large-scale recycling treatment; the sol agent mainly contains components such as acetone, which has high toxicity, long time consumption, incomplete infiltration and low environmental friendliness; the ultrasonic vibration has the disadvantages of ripple damage to the internal part of the cell, etc.

[0004] Correspondingly, there is a need in the art for a new technical solution to solve the above problems. CONTENT OF THE UTILITY MODEL

[0029] The traditional battery pack is assembled from cells to form a module, and then the module is installed in the battery pack to form a "cell-module-battery pack" three-level assembly mode. The CTP battery pack skips the module link, and the cells are fixed on the cold plate through the structural adhesive, and the structural frame is used to apply a pre-tightening force to the cells to form an interference fit, so that the cells are directly integrated on the battery pack.

[0030] The application relates to a battery pack, which is combined with Figure 1 and Figure 2 As shown in the figure, the battery pack 100 comprises a cell block 101, a cold plate 102 and a structural frame 103. The cell block 101 is composed of a plurality of cells. The cold plate 102 is connected to the bottom of the cell block 101 through a structural adhesive layer 104. The structural frame 103 is arranged around the cell block 101.

[0031] The application provides a battery pack disassembling device, which is applied to the above-mentioned battery pack, which is combined with Figures 1 to 6 As shown in the figure, the battery pack disassembling device comprises a heating mechanism 200, an edge lifting mechanism 300, a tearing mechanism 400 and a glue shoveling mechanism 500.

[0032] The heating mechanism 200 is used for heating the cold plate 102 and the structural adhesive layer 104. The edge lifting mechanism 300 is used for lifting the edge of the cold plate 102 to form a rolled edge. The tearing mechanism 400 is used for clamping the rolled edge, and the tearing mechanism 400 can be translated relative to the battery pack to pull and tear the cold plate 102. The glue shoveling mechanism 500 is used for shoveling and clamping the structural adhesive layer 104, and the glue shoveling mechanism 500 can be translated relative to the battery pack to pull and tear the structural adhesive layer 104.

[0033] Under the premise of adopting the above technical solutions, in the disassembling process of the battery pack, the heating mechanism 200 is used to heat the cold plate 102, so as to reduce the bonding force between the cold plate 102 and the structural adhesive layer 104. After the bonding force between the cold plate 102 and the structural adhesive layer 104 is reduced, the edge lifting mechanism 300 is used to lift the edge of the cold plate 102 to form a rolled plate, and the tearing mechanism 400 clamps the rolled edge to translate and tear the cold plate 102. After the cold plate 102 is torn, the heating mechanism 200 is used to heat the structural adhesive layer 104, so as to reduce the bonding force of the structural adhesive layer 104. Then, the glue shoveling mechanism 500 is used to shovel and tear the structural adhesive layer 104, so that the disassembling of the structural adhesive layer 104 can be completed. The application reduces the bonding force of the structural adhesive through the hot pressing process, the hot pressing time is short and the contact area is controllable, the battery pack can be prevented from being damaged by heat, the heating mechanism 200 cooperates with the edge lifting mechanism 300, the tearing mechanism 400 and the glue shoveling mechanism 500, the cold plate 102 and the structural adhesive layer 104 can be completely torn, long-time temperature control is not needed, sol agent, ultrasonic vibration and manual operation are not needed, the energy consumption of the disassembling of the battery pack is reduced, the disassembling efficiency and the disassembling completeness are improved, and fine and lossless disassembling of the battery pack is realized.

[0034] The heating mechanism 200 is used for heating the cold plate 102 and the structural adhesive layer 104. The edge lifting mechanism 300 is used for lifting the edge of the cold plate 102 to form a rolled edge. The tearing mechanism 400 is used for clamping the rolled edge, and the tearing mechanism 400 can be translated relative to the battery pack to pull and tear the cold plate 102. The glue shoveling mechanism 500 is used for shoveling and clamping the structural adhesive layer 104, and the glue shoveling mechanism 500 can be translated relative to the battery pack to pull and tear the structural adhesive layer 104.

[0035] In some embodiments, the heating mechanism 200 comprises a high-temperature panel 201. As shown in the figure, the high-temperature panel 201 can be in contact with the cold plate 102 to heat the cold plate 102, and as shown in the figure Figure 2 Figure 5 ​As shown, the high-temperature panel 201 can be in contact with the structural adhesive layer 104 to heat the structural adhesive layer 104.

[0036] By setting the high-temperature panel 201 in contact with the cold plate 102 and the structural adhesive layer 104, the cold plate 102 and the structural adhesive layer 104 can be uniformly and quickly heated, the heating time is short, and the heating effect on the internal battery cells of the battery pack is extremely low.

[0037] In some embodiments, the heating mechanism 200 further comprises a lifting platform 202, and the high-temperature panel 201 is arranged on the lifting platform 202, and the lifting platform 202 can drive the high-temperature panel 201 to rise and fall.

[0038] The exposed cold plate 102 is disposed by the high-temperature panel 201, including: when the temperature of the high-temperature panel 201 reaches a first preset temperature, the high-temperature panel 201 moves towards the cold plate 102, the high-temperature panel 201 flexibly contacts the cold plate 102, heat is transferred from the high-temperature panel 201 to the cold plate 102, and the high-temperature panel 201 leaves the cold plate 102 after contacting the cold plate 102 for a preset time. In this way, the adhesion of the structural adhesive layer 104 to the cold plate 102 can be reduced by high temperature, facilitating the subsequent removal of the cold plate 102, and the high-temperature panel 201 contacts the entire cold plate 102 to uniformly and quickly heat the cold plate 102, the heating time is short, and the heating effect on the internal battery cells of the battery pack is extremely low.

[0039] After the cold plate 102 is removed, the structural adhesive layer 104 is exposed, and the exposed structural adhesive layer 104 is disposed by the high-temperature panel 201, including: when the temperature of the high-temperature panel 201 reaches a second preset temperature, the high-temperature panel 201 moves towards the structural adhesive layer 104, the high-temperature panel 201 flexibly contacts the structural adhesive layer 104, heat is transferred from the high-temperature panel 201 to the structural adhesive layer 104, and the high-temperature panel 201 leaves the structural adhesive layer 104 after contacting the structural adhesive layer 104 for a preset time. After the heat pressing process time ends, the structural adhesive layer 104 is removed by the glue shoveling mechanism 500, thereby completing the back disassembly.

[0040] In some embodiments, in combination with Figure 4 As shown, the heating mechanism 200 further comprises a heating controller 203 and a time controller 204. The heating controller 203 is used to control the heating of the high-temperature panel 201, and the time controller 204 is used to control the contact time of the high-temperature panel 201 with the cold plate 102 or the structural adhesive layer 104. Specifically, after the heating controller 203 controls the high-temperature panel 201 to reach a preset temperature, the high-temperature panel 201 moves down, the high-temperature panel 201 flexibly contacts the cold plate 102 or the structural adhesive layer 104, and after the contact time reaches a preset time, the time controller 204 automatically triggers the high-temperature panel 201 to rise to leave the cold plate 102 or the structural adhesive layer 104.

[0041] For edge-starting mechanism 300.

[0042] In some embodiments, combined with Figure 3 As shown, the edge-lifting mechanism 300 includes a top claw 301, a lifting assembly 302, and a first linkage assembly 303. The top claw 301 is rotatably disposed on the side of the structural adhesive layer 104 away from the cold plate 102. The lifting assembly 302 is connected to the top claw 301 and can push the top claw 301 toward the cold plate 102, lifting the edge of the cold plate 102. After the edge of the cold plate 102 is lifted, the first linkage assembly 303 drives the top claw 301 to rotate, so that the edge curls to form a rolled edge. After the high-temperature panel 201 heats the cold plate 102, reducing the adhesion between the cold plate 102 and the structural adhesive layer 104, the lifting assembly 302 pushes the top claw 301 toward the side where the cold plate 102 and the structural adhesive layer 104 are located. Under the push of the lifting assembly 302, the edge-lifting mechanism 300 lifts the edge of the cold plate 102, separating the edge of the cold plate 102 from the structural adhesive layer 104, thus achieving edge lifting of the cold plate 102. After the cold plate 102 is raised, the first connecting rod assembly 303 drives the top claw 301 to rotate, causing the raised edge of the cold plate 102 to curl and form a rolled edge.

[0043] In some embodiments, combined with Figure 3 As shown, the top claw 301 includes a first end and a second end disposed opposite to each other. The surface of the first end facing the battery pack is provided with a sharp corner 3011, and the surface of the sharp corner 3011 facing the second end is provided with a concave arc-shaped surface. The second end is used to connect with the first connecting rod assembly 303. By providing the sharp corner 3011, it is easy to push open the edge of the cold plate 102. By providing the surface of the sharp corner 3011 facing the second end with a concave arc-shaped surface, when the first connecting rod assembly 303 rotates, the edge of the cold plate 102 that is pushed up will curl to form a rolled edge under the action of the arc-shaped surface.

[0044] Understandably, the first linkage assembly 303 pulls the second end of the top claw 301 to rotate toward the side away from the cold plate 102, while the first end of the top claw 301 rotates toward the side close to the cold plate 102. The edge of the cold plate 102 that is lifted comes into contact with the arc-shaped surface of the sharp corner 3011 and curls under the guidance of the arc-shaped surface to form a rolled edge.

[0045] In some embodiments, combined with Figure 4 and Figure 6 As shown, the battery pack disassembly device also includes a translation mechanism 600, which is used to pull the tearing mechanism 400 and the adhesive removal mechanism 500 to translate. After the tearing mechanism 400 clamps the rolled edge of the cold plate 102, the translation mechanism 600 pulls the tearing mechanism 400 to translate and tear off the cold plate 102. The translation mechanism 600 can also pull the adhesive removal mechanism 500 to translate to remove the heated structural adhesive layer.

[0046] For the tearing mechanism 400.

[0047] In some embodiments, in combination with Figure 4 As shown, the tearing mechanism 400 includes a fixed assembly 401 and a second linkage mechanism 402. The fixed assembly 401 is used to clamp the edge of the cold plate 102. The second linkage mechanism 402 is used to connect the fixed assembly 401 and the translation mechanism 600. After the cold plate 102 is formed, the fixed assembly 401 in the tearing mechanism 400 clamps the edge of the cold plate 102, the translation mechanism 600 pulls the second linkage mechanism 402 to move horizontally, and the second linkage mechanism 402 drags the cold plate 102 to tear during the horizontal movement. The hinge on the second linkage mechanism 402 can automatically adjust the optimal tearing angle.

[0048] For the glue scraping mechanism 500.

[0049] In combination with Figure 6 As shown, the glue scraping mechanism 500 includes a scraping head 501, a clamping assembly 502, and a third linkage mechanism 503. The scraping head 501 is used to scrape the structural adhesive layer 104. The clamping assembly 502 is arranged on the scraping head 501 and is used to clamp the scraped structural adhesive layer 104. The third linkage mechanism 503 is used to connect the scraping head 501 and the translation mechanism 600. By using the sharp edge of the scraping head 501 to scrape the heated structural adhesive, and by designing the specific bending angle and depth of the scraping head, the scraped structural adhesive enters the clamping assembly 502, the structural adhesive touches the automatic clamping switch of the clamping assembly 502, and the structural adhesive is automatically clamped. The translation mechanism 600 pulls the third linkage mechanism 503 to move horizontally, and the third linkage mechanism 503 drags the structural adhesive layer to tear during the horizontal movement. The hinge on the third linkage mechanism 503 can automatically adjust the optimal tearing angle during the translation process.

[0050] In some embodiments, after the heating mechanism completes heating the cold plate 102, the edge lifting mechanism 300 lifts the edge of the cold plate 102. Hot pressing the cold plate 102 helps to reduce the bonding force between the cold plate 102 and the structural adhesive, facilitating the tearing of the cold plate 102.

[0051] In some embodiments, after the cold plate 102 is torn and the heating mechanism completes heating the structural adhesive layer 104, the glue scraping mechanism 500 scrapes and clamps the structural adhesive layer 104. Hot pressing the structural adhesive layer helps to reduce the bonding force of the structural adhesive layer, facilitating the tearing of the structural adhesive layer.

[0052] In some embodiments, in combination with Figure 1As shown, the battery pack disassembling device further comprises a turnover mechanism 700 and a plurality of fixing clamps 800. The turnover mechanism 700 comprises a fixed frame 701. The fixing clamps 800 are used to fix the connecting structure frame 103 and the fixed frame 701. The turnover mechanism 700 can drive the fixed frame 701 to turn over, thereby driving the battery pack to turn over. The fixed frame 701 of the battery pack and the turnover mechanism 700 are fixed by the fixing clamps 800. The turnover mechanism 700 can drive the battery pack to turn over by turning over the fixed frame 701, thereby facilitating the disassembly of the battery pack.
