[0001] The present invention relates to the technical field related to battery pack processing, and in particular to a device for peeling off a water-cooling plate of a battery pack. Background Art

[0002] Today, the new energy industry is developing rapidly, and the installed capacity of battery packs is getting larger and larger. As the years of use increase, more and more battery packs are running out of service life and are being recycled, which requires the battery packs to be disassembled.

[0003] After massive searches, it was found that the existing Chinese patent announcement number is CN220021201U, which discloses a water-cooled plate insulating film peeling device, including a hot water immersion tank, on which a water-cooled plate rotating tooling is assembled and connected; the water-cooled plate rotating tooling includes a rotating component arranged on left and right sides, the rotating component includes a rotating seat, a connecting shaft is fixedly connected between the rotating seats, and a plurality of folded rotating arm rods are assembled and connected on the side walls of the rotating seat facing each other, and the free ends of the folded rotating arm rods are respectively fixedly connected with fixed pin screws, and the fixed pin screws are threadedly connected with positioning nuts for positioning the water-cooled plate; the water-cooled plate rotating tooling also includes a driving motor for driving the rotating component to rotate, and the output shaft of the driving motor is fixedly assembled on one side of the rotating seat; the above method realizes hot soaking of the insulating film on the water-cooled plate in a rapid heat treatment manner, and lifts it from the hot water in a rotation manner after hot running to facilitate film stripping, which effectively improves the processing efficiency of the cold plate.

[0004] In order to ensure the sealing and safety of battery packs on the market, the battery cells and the water-cooling plate at the bottom of the box are basically sealed with glue.

[0040] A plurality of limit blocks are installed on the frame 11 above the lifting plate 19 and on the frame 11 below the roller fixing plate 20. The limit blocks are rubber blocks.

[0041] The first embodiment of the present invention:

[0042] The present invention designs a device for peeling off the water-cooling plate of a battery pack, which can stably peel off the water-cooling plate of the battery pack without cutting or violent tearing, avoiding damage to the battery core or short circuit fire, and improving the recovery yield; it does not need to be frozen for a long time, which improves the disassembly efficiency; it does not need to be soaked in liquid medicine, which does not pollute the environment and does not harm the human body. Through actual production verification, the disassembly is simple, the efficiency is fast, and the recovery yield is high.

[0043] like Figure 1 , including a roller lifting mechanism 1 and a peeling roller assembly 2, wherein the welding assembly 2 is installed between the roller lifting mechanisms 1 on both sides.

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

[0045] The frame 11 is installed on the table substrate by bolts for fixing the structural base; the electric cylinder mounting plate 12 is screwed to the upper surface of the frame 11 for installing and fixing the servo electric cylinder 13; one end of the floating joint 14 is screwed to the output shaft of the servo electric cylinder 13, and the other end is screwed to the lifting plate 19, and the lifting plate 19 is fixed to the slider of the linear guide 18 by screws; the linear guide 18 is installed on the frame 11 to ensure the parallelism of the linear guide 18; the motor seat 15 is fixed to the sliders on the four linear guides 18, and the servo reducer 17 is installed and fixed on one side of the motor seat 15, and the other side is screwed together with the roller fixing plate 20; the belt bearing 22 is installed on the roller fixing plate 20; the transmission shaft 23 is inserted into the hole of the belt bearing 22, and the output shaft of the servo reducer 17 and the transmission shaft 23 are connected by the safety coupling 16 to realize the power transmission of the stripping roller. The floating pull plate 21 is screwed onto the roller fixing plate 20, and its internal notch is inserted into two bosses on the lifting pull plate 19 to achieve sliding limit.

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

[0047] The stripping roller 201 has a transmission shaft 23 installed on both sides by bolts, and the inner side thereof cooperates with the shaft boss through a step hole to realize high torque transmission; the stripping roller 201 has a full-length notch, and multiple fixed clamps 202 are located at the notch. When switching products, the position of the fixed clamps 202 can be adjusted to achieve clamping of water-cooled plates of different widths.

[0048] Working process of the present invention:

[0049] During production, the battery pack is manually placed under the device, and the servo electric cylinders 13 on both sides descend, and then the peeling roller assembly 2 descends until it presses the box body. Then the head of the water-cooled plate is manually placed into the groove of the peeling roller 201, and the water-cooled plate is clamped by the clamping plate 202. After starting the equipment, the servo reducers 17 on both sides simultaneously provide large torque output, driving the peeling roller assembly 2 to rotate, and the water-cooled plate will automatically wind on the peeling 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, and the peeling roller assembly 2 stops rotating, and the equipment alarms. At the same time, the safety coupling 16 can be automatically reset. When it is necessary to continue peeling, the servo reducers 17 on both sides can be started to resume the peeling action. Similarly, during the stripping process, since the water-cooled plate is wound on the stripping roller 201, its outer diameter will continue to increase. Considering this point, the linear guide 18, the lifting plate 19, the roller fixing plate 20, and the floating plate 21 in the present invention are combined into a set of floating mechanisms, and the stripping roller assembly 2 is fixed on the roller fixing plate 20. When the roll diameter increases, the slots opened by the lifting plate 19 can move freely on the boss of the floating plate 21, and the stroke is determined by the slot size of the lifting plate 19. Through this floating mechanism, the mechanism will not be subjected to hard impact during the stripping process, and flexible stripping is achieved. The servo reducers 17 on both sides continue to rotate until the water-cooled plate is completely rolled on the stripping roller 201. The end of the water-cooled plate on the stripping roller 201 is manually fixed to a clamping point outside the device, and the servo reducer 17 is reversed, and the water-cooled plate is then automatically unwound and flattened. After being completely flattened, the clamping plate 202 is released and the water-cooled plate can be taken out.

[0050] This device is used for automatic stripping of the water-cooling plate of the Pack battery pack. The main functions are: clamping the water-cooling plate of the battery pack; winding the water-cooling plate for stripping and separating it from the Pack battery pack box; unwinding the water-cooling plate on the flattening roller for unloading; it is compatible with 2-meter wide battery packs and has no length restrictions.

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

[0052] By driving the stripping roller to rotate, flexible stripping of the water-cooled plate is achieved. According to the length of the roller, it can be compatible with a wide range of product changes and has high flexibility. In actual production, it has high efficiency, high safety, minimal damage to the battery, and greatly improved recycling yield.
