Description

Technical Field

[0001] This utility model relates to the technical field of battery pack processing, and in particular to a device for peeling off the water cooling plate of a battery pack. Background Technology

[0002] With the rapid development of the new energy industry, the installed capacity of battery packs is increasing. As their service life increases, more and more battery packs will reach the end of their service life and have to be recycled, which will require dismantling.

[0003] A search revealed a Chinese patent publication number, CN220021201U, which discloses a device for removing the insulating film from a water-cooled plate. The device includes a hot water soaking tank, on which a water-cooled plate rotating fixture is mounted. The rotating fixture includes rotating components on both sides, each component comprising a rotating base. A connecting shaft is fixedly connected between the rotating bases. Several folded rotating arms are mounted on the opposing sidewalls of the rotating bases. Each folded rotating arm has a fixed pin screw at its free end, and a positioning nut for positioning the water-cooled plate is threaded onto the fixed pin screw. The rotating fixture also includes a drive motor for rotating the rotating components, with the output shaft of the drive motor fixedly mounted on one side of the rotating base. This method achieves rapid heat treatment to soak the insulating film on the water-cooled plate, followed by rotation to lift it from the hot water for easy film removal, effectively improving the processing efficiency of the cold plate.

[0004] To ensure sealing and safety, battery packs on the market generally use potting compound to seal the cells and the water-cooling plate at the bottom of the casing. Once the compound cures, the structure is very strong, making disassembly extremely difficult. Current disassembly methods all have certain drawbacks, such as destructive disassembly, which has a very low recycling rate; frozen disassembly, which is time-consuming, requiring the battery pack to be frozen for more than 24 hours; and soaking in chemicals, which causes significant pollution and is harmful to human health.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a device for peeling off the water cooling plate of the battery pack, so as to make it more industrially valuable. Utility Model Content

[0013] As a further improvement of this utility model, the peeling roller is mounted on the roller fixing plate through a drive shaft and a bearing seat, and the servo reducer is connected to the inner drive shaft through a safety coupling.

[0014] As a further improvement of this utility model, the lifting plate moves vertically along a linear guide rail mounted on the frame via a first slider.

[0015] As a further improvement of this utility model, the roller fixing plate moves vertically along a linear guide rail mounted on the frame via a second slider.

[0016] As a further improvement of this utility model, at least one sensing plate is installed on the lifting plate, and a sensor adapted to the aforementioned sensing plate is installed on the roller fixing plate directly below the sensing plate.

[0034] like Figures 1-4 As shown, a device for peeling water cooling plates from a battery pack includes a peeling roller assembly 2, which includes a peeling roller 201.

[0038] The lifting plate 19 moves vertically along the linear guide rail 18 mounted on the frame 11 via a first slider. The roller fixing plate 20 moves vertically along the linear guide rail 18 mounted on the frame 11 via a second slider.

[0039] At least one sensing plate is installed on the lifting plate 19, and a sensor adapted to the sensing plate is installed on the roller fixing plate 20 directly below the sensing plate.

[0040] Several limit blocks, which are rubber blocks, are installed on the frame 11 above the lifting plate 19 and on the frame 11 below the roller fixing plate 20.

[0041] The first embodiment of this utility model:

[0042] This invention designs a device for peeling off the water-cooling plate of a battery pack. It can stably peel off the water-cooling plate without cutting or violent tearing, avoiding damage to the battery cells or short circuits and fires, thus improving the recycling yield. It eliminates the need for prolonged freezing, improving dismantling efficiency; and it eliminates the need for soaking in chemicals, causing no environmental pollution and no harm to human health. Actual production verification shows that dismantling is simple, efficient, and yields a high recycling rate.

[0043] like Figure 1 It includes a roller lifting mechanism 1 and a roller stripping assembly 2, wherein the welding assembly 2 is installed between the two roller lifting mechanisms 1.

[0044] like Figure 2 and 3 The stripping roller lifting mechanism 1 shown includes a frame 11, an electric cylinder mounting plate 12, a servo electric cylinder 13, a floating joint 14, a motor base 15, a safety coupling 16, a servo reducer 17, a linear guide rail 18, a lifting plate 19, a roller fixing plate 20, a floating plate 21, a bearing with a seat 22, and a drive shaft 23.

[0045] The frame 11 is bolted to the table base plate for structural base fixation; the electric cylinder mounting plate 12 is screwed to the upper surface of the frame 11 for mounting and fixing the servo electric cylinder 13; one end of the floating joint 14 is screwed onto the output shaft of the servo electric cylinder 13, and the other end is screwed onto the lifting plate 19, which is fixed to the slider of the linear guide rail 18 with screws; the linear guide rail 18 is mounted on the frame 11 to ensure its parallelism; the motor base 15 is fixed on the slider of the four linear guide rails 18, and a servo reducer 17 is mounted on one side of the motor base 15, while the other side is screwed together with the roller fixing plate 20; a seated bearing 22 is mounted on the roller fixing plate 20; the drive shaft 23 is fitted into the hole of the seated bearing 22, and a safety coupling 16 is used to connect the output shaft of the servo reducer 17 and the drive shaft 23 to realize the power transmission of the stripping roller. The floating pull plate 21 is locked to the roller fixing plate 20 by screws, and its internal groove is inserted into two protrusions on the lifting pull plate 19 to achieve sliding limit.

[0046] like Figure 4 The stripping roller assembly 2 shown includes a drive shaft 23, a stripping roller 201, and a clamping plate 202.

[0047] The peeling roller 201 is bolted to both sides with a drive shaft 23, and its inner side is engaged with the shaft boss through a stepped hole to achieve high torque transmission; the peeling roller 201 has a continuous notch, and multiple fixed clamping plates 202 are provided at the notch. When switching products, the position of the fixed clamping plates 202 can be adjusted to clamp water-cooled plates of different widths.

[0048] The working process of this utility model:

[0049] During production, the battery pack is manually placed under the device, causing the servo cylinders 13 on both sides to descend, which in turn lowers the stripping roller assembly 2 until it presses against the housing. Then, the head of the water-cooled plate is manually placed into the groove of the stripping roller 201, and clamped by the clamping plate 202. After the equipment is started, the servo reducers 17 on both sides simultaneously provide high torque output, driving the stripping roller assembly 2 to rotate. At this time, the water-cooled plate automatically winds onto the stripping roller 201. During the winding process, the safety coupling 16 is used to protect the mechanism. When the torque is abnormal, it will automatically disengage from the transmission. At this time, the servo reducer 17 rotates, while the stripping roller assembly 2 stops rotating, and the equipment alarms. Simultaneously, the safety coupling 16 can automatically reset. If stripping needs to continue, activating the servo reducers 17 on both sides will resume the stripping action. Similarly, during the peeling process, the outer diameter of the water-cooled plate continuously increases as it is wound onto the peeling roller 201. Considering this, the linear guide 18, lifting plate 19, roller fixing plate 20, and floating plate 21 are combined into a floating mechanism. The peeling roller assembly 2 is fixed to the roller fixing plate 20. When the roll diameter increases, the slot in the lifting plate 19 can move freely on the protrusion of the floating plate 21, with the stroke determined by the slot size of the lifting plate 19. Through this floating mechanism, the mechanism is not subjected to hard impact during the peeling process, achieving flexible peeling. The servo reducers 17 on both sides rotate continuously until the water-cooled plate is completely wound onto the peeling roller 201. The end of the water-cooled plate on the peeling roller 201 is manually fixed to a clamping point outside the device. The servo reducer 17 reverses, and the water-cooled plate is automatically unwound and flattened. After complete flattening, the clamping plate 202 is released, and the water-cooled plate can be removed.

[0050] This device is used for automatic stripping of water-cooled plates from battery packs. Its main functions include: clamping the water-cooled plates; stripping the water-cooled plates from the battery pack housing; and unloading the water-cooled plates from the unwinding rollers. It is compatible with battery packs up to 2 meters wide, with no length limitation.

[0051] The automatic peeling of the battery pack water-cooling plate is achieved through a drive motor, peeling roller, lifting cylinder, and floating pull plate, and it has flexible functions for different scenarios and product applications.

[0052] By driving the stripping roller to rotate, the water-cooled plate can be flexibly peeled off. It can accommodate a wide range of product changes depending on the length of the roller. It is highly flexible, efficient, safe, and causes minimal damage to the battery in actual production, and greatly improves the recycling yield.
