[0058] A control system, connected to the precooling chamber 1 and the spray chamber 6 respectively, wherein the control system divides the control mode of the control system into a first adhesive removal mode and a second adhesive removal mode based on the adhesive properties of the battery module;
[0059] The control system includes a judgment module, the control system obtains control instructions according to different adhesive properties, the judgment module judges the degumming mode corresponding to the control instruction, and the control system limits the configuration parameters of the precooling chamber 1 and the spraying chamber 6 based on the first degumming mode and the second degumming mode respectively to realize the degumming operation of the battery module with different adhesive properties, wherein the precooling chamber 1 is arranged at the front end of the battery module degumming device; the hammering chamber 2 is arranged at the rear end of the precooling chamber 1; the spraying chamber 6 is arranged at the rear end of the hammering chamber 2; the screening chamber 8 is arranged at the rear end of the spraying chamber 6; the medicine storage tank 4 is arranged on the side of the spraying chamber 6; the mixer 5 is arranged on the front side of the medicine storage tank 4; the transmission system 9 is respectively arranged at the rear end of the precooling chamber 1, the hammering chamber 2 and the spraying chamber 6, for connecting and transmitting the front and rear end inflow and outflow; the liquid distribution and gas distribution system 10 is arranged on the upper and side of the cavity of the spraying chamber 6.
[0060] In order to realize different glue removal modes, the control system also includes a user interface and a threshold setting module, a precooling cabin control module and a spray cabin control module respectively connected to the user interface; the threshold setting module is used to set a first adhesive attribute threshold and a second adhesive attribute threshold, and use the adhesive attribute threshold as the only judgment standard of the judgment module, the first adhesive attribute threshold corresponds to the first glue removal mode, and the second adhesive attribute threshold corresponds to the second glue removal mode; the precooling cabin control module adjusts the configuration parameters of the precooling cabin 1 based on the precooling cabin control model, and the precooling cabin control model outputs the first configuration parameters and the second configuration parameters of the precooling cabin 1 based on the adhesive properties; the spray cabin control module adjusts the configuration parameters of the spray cabin 6 based on the spray cabin control model, and the spray cabin control model outputs the first configuration parameters and the second configuration parameters of the spray cabin 6 based on the adhesive properties;

[0062] The adhesive property is the ratio of the adhesive area to the battery module area. The ratio is determined based on image recognition technology. Specifically, the image data of the battery module to be processed is first obtained, and the image data can be obtained by camera shooting, scanner scanning, etc. For example, in industrial production, an industrial camera can be used to shoot the battery module to be processed, and the product image can be obtained to analyze the size ratio of the adhesive; since the original image may have noise, this will affect the subsequent image recognition and analysis. Therefore, in this embodiment, Gaussian filtering is used to denoise the image.

After the image recognition is completed, the features of different elements are extracted, the relevant parameters of different elements are measured, and the ratio between them is calculated. That is, the areas of different elements are measured, the area ratio is calculated, and then the ratio of the adhesive area to the battery module area is obtained.
[0063] Continue to refer to Figure 1 In the above, a precooling module 12 and a quick freezing module 13 are arranged inside the precooling chamber 1. The precooling module 12 is arranged in the front part of the precooling chamber 1 for precooling and reducing the subsequent freezing pressure.

[0065] It should be noted that the precooling chamber control model should normally output the freezing temperature and freezing time, but in this embodiment, the freezing time is determined by the conveying speed of the freezing chamber conveyor belt 14, that is, the faster the conveying speed of the freezing chamber conveyor belt 14, the shorter the time the battery module stays in the precooling chamber 1, and the slower the conveying speed of the freezing chamber conveyor belt 14, the longer the time the battery module stays in the precooling chamber 1, so the freezing time can be converted into the conveying speed of the freezing chamber conveyor belt 14.

After labeling, the adhesive properties are used as the input of the second neural network structure, and the flow parameters and flip speeds are used as the output of the second neural network structure for iterative training, so as to obtain a spray chamber control model that outputs the flow parameters of the electromagnetic valve 33 and the flip speed of the flipping barrel 25 based on the adhesive properties. After the flow parameters of the electromagnetic valve 33 are determined, the flow parameters of the electromagnetic liquid control valve 60 are also determined. In this embodiment, the opening of the electromagnetic gas control valve 61 can be constrained based on the flow parameters of the electromagnetic liquid control valve 60 according to the preset atomization effect. For example, the feed flow rate of the spray chamber is 100kg / h-2000kg / h; the rotation speed of the turning drum is 10-60r / min; the spray flow rate of the atomizing spray head is 100ml / min-1000ml / min, then the flow parameter of the electromagnetic liquid valve 60 is 100ml / min-1000ml / min, and the opening of the electromagnetic air valve 61 can be set according to demand.
[0071] The above-mentioned first neural network structure is the same as the second neural network structure, both of which include an input layer, a hidden layer and an output layer. The input layer has only one node for receiving input ratio data. The neurons in the hidden layer use the nonlinear activation function ReLU to increase the nonlinear expression ability of the network. The output layer includes two nodes, which correspond to the outputs of two control parameters respectively. The activation function of the output layer is selected according to the properties of the control parameters. Since the control parameters in this embodiment are discrete values within a certain range, the nonlinear activation function Softmax is used.

The infusion port 49 is at the right top of the mixer 5, and is used to input the required liquid medicine. The mixing reamer 50 is inside the mixer 5, connected to the external mixing motor 54 for rotation, and is used to mix the degumming agent to ensure the homogenization of each agent. The regeneration tank 53 is on the left side of the mixer 5, and the regeneration pipe 52 is at the lower end of the regeneration tank 53. The regeneration pipe 52 receives the secondary agent separated by the spray cabin 6, and temporarily stores it in the regeneration tank 53. The characteristics of the agent itself are used to separate part of the regenerated agent and reuse it in the mixer 5.
[0075] For example, reference Figure 1As shown, the transmission system 9 includes a No. 1 transmission ladder 3, a feed hopper 21, a conveyor belt 22, and a No. 2 transmission ladder 7. The No. 1 transmission ladder 3 is at the lower end of the hammer cabin 2, and transmits the loose battery modules to the spray cabin 6. The No. 2 transmission ladder 7 is at the right end of the spray cabin 6, and transmits the debonded battery modules and slag to the screening cabin 8. The No. 1 transmission ladder 3 and the No. 2 transmission ladder 7 both include a feed hopper 21 and a conveyor belt 22. The feed hopper 21 is on the upper part of the conveyor belt 22, and the conveyor belt 22 moves along the set feeding direction by relying on the external electrode.
[0076] For example, reference Figure 1-6 As shown, the liquid distribution and gas distribution system 10 is divided into a liquid distribution system and a gas distribution system, wherein the gas distribution system includes an air inlet pipe 57, an air pump 58, an electromagnetically controlled gas valve 61, and an air distribution pipe 62. The air inlet pipe 57 is arranged at the side section of the spray cabin 6, the air pump 58 is arranged at the rear end of the air inlet pipe 57, the electromagnetically controlled gas valve 61 is arranged in the gas distribution pipe 62, and the gas distribution pipe 62 is arranged inside the spray cabin 6. The protective gas used can be one or any combination of nitrogen, carbon dioxide, helium, argon, neon, krypton and xenon. The liquid distribution system includes a liquid inlet pipe 56, an electromagnetically controlled liquid valve 60, a booster pump 59, and a liquid distribution pipe 63. The liquid inlet pipe 56 is arranged at the side section of the spray cabin 6, the booster pump 59 is arranged at the rear end of the liquid inlet pipe 56, the electromagnetically controlled liquid valve 60 is arranged in the liquid distribution pipe 63, the liquid distribution pipe 63 is arranged inside the spray cabin 6, and the gas distribution pipe 62 and the liquid distribution pipe 63 are arranged in the spray layer 31. The mixed degumming agent of the battery module degumming device can be one or more of ethanol, acetone, petroleum ether, ethyl acetate, isopropanol, butanone, xylene, toluene, sodium hydroxide solution caustic soda, acetic acid, citric acid, and sodium dodecylbenzene sulfonate. For example, the manufacturing material of the battery module degumming device can be one or more of 44 steel, 35 steel, A3 steel, 40Cr alloy structural steel, HT149 gray cast iron, 65Mn steel, 0Cr18Ni9 steel, DCCr12MoV chrome steel, SKD11 chrome steel, D2 steel, and SKD11 (SLD) chrome steel.
[0077] When the battery module degumming device of this embodiment is working, it first determines the adhesive properties of the battery module to be processed through image recognition technology, that is, the ratio of the adhesive area to the battery module area, and determines the degumming mode that should be adopted based on the current adhesive properties through the judgment module, and then determines the execution instructions called by the pre-cooling chamber control module and the spray chamber control module, that is, when the first degumming mode is presented on the user interface, the pre-cooling chamber control module and the spray chamber control module are required to respond and call the first execution instruction corresponding to the first degumming mode in the control system; and when the second degumming mode is presented on the user interface, the pre-cooling chamber control module and the spray chamber control module are required to respond and call the second execution instruction corresponding to the second degumming mode in the control system. Then, the freezing temperature of the quick freezing module 13, the conveying speed of the freezing chamber conveyor belt 14, the flow parameters of the solenoid valve 33 and the turning speed of the turning barrel 25 are determined.
[0078] Then the control system starts the precooling chamber 1, the hammer chamber 2, the mixer 5, the medicine storage tank 4, the liquid and gas distribution system 10, the spray chamber 6, the screening chamber 8, and the transmission system 9 in sequence.
[0079] When the precooling chamber 1 is working, the retired battery module is input into the precooling chamber 1 through the precooling chamber feed port 11, and is transmitted backward under the drive of the freezing chamber conveyor belt 14. It first passes through the precooling module 12 to pre-lower the surface temperature of the module, and then passes through the quick freezing module 13 to quickly freeze-dry the adhesive and soft board on the surface of the battery module and make them brittle and fragile. The freeze-dried module slides out along the precooling chamber discharge port 15.
[0080] When the hammer chamber 2 is working, the freeze-dried module slides along the pre-cooling chamber discharge port 15 to the hammer chamber feed port 16, and falls to the impact plate 19 with adjustable hammer head spacing through the hammer chamber guide plate 17. The hammer head 18 hammers the freeze-dried retired battery module through the support frame 28 relying on the rotation of the motor. After a certain period of hammering, the rubber sheet of the retired battery module and part of the battery module adhesive fall off, and each battery module is loose and discharged from the discharge port 20 at the bottom of the hammer chamber.
[0081] When the No. 1 transmission ladder 3 is working, the battery modules and the crushed slag materials fall from the discharge port 20 at the bottom of the hammer cabin to the feed hopper 21 on the transmission ladder, and are transported to the front end of the spray cabin 6 along the direction of the conveyor belt 22.
[0082] When the mixer 5 and the medicine storage tank 4 are working, the solid degumming agent enters the mixer 5 from the dosing port 48 of the mixer and the liquid solvent enters the mixer from the infusion port 49 of the mixer, and the mixing reamer 50 is driven by the mixing motor 54 to continuously stir until the degumming liquid is uniform and homogeneous. The mixed degumming liquid is discharged through the liquid outlet pipe 55 at the lower end of the mixer, and is accelerated by the liquid guide pump 45 to be drawn into the medicine storage tank 4.
[0083] When the liquid distribution and gas distribution system 10 is working, the liquid outlet distribution valve 46 is adjusted to the passage, and the degumming liquid is pumped into the liquid distribution pipe 63 from the medicine storage tank 4 through the liquid inlet pipe 56 by the pressure pump 59, and the liquid flow of each liquid distribution pipeline network 40 is adjusted by the electromagnetic liquid control valve 60. The protective gas is pumped into the gas distribution pipe 62 from the gas tank or the gas generator through the air pump 58 through the air inlet pipe 57, and the gas flow of each distribution gas pipe 62 is adjusted by the electromagnetic gas control valve 61.
[0084] When the spray chamber 6 is working, the battery module and the slag material fall into the spray chamber feed port 23 from the upper feed hopper 21, and the battery module slides to the tipping barrel 25 after the spray position is adjusted by the spray chamber guide plate 24. At the same time, the solenoid valve 33 controls the atomizing spray head 32 to spray high-speed degumming liquid mist, and the tipping barrel 25 is driven by the external electrode to move clockwise in the direction of the spray chamber. The battery module is rolled by several tipping barrels 25 to fully degumming each surface. The degummed slag and condensed droplets are separated and filtered by the gauze 26 on the tipping barrel 25 and fall into the secondary agent groove 36. The scraper 34 moves back and forth on the upper part of the secondary agent liquid surface to scrape off the scum on the agent surface. The scum is discharged from the slag outlet 64, and the secondary agent is collected in the regeneration pipe 52 along the liquid separation pipe 38 through the liquid aspirator 37. The battery module and the slag material after degumming are transported to the spray chamber discharge port 41 by several tipping barrels 25.
[0085] When the No. 2 transmission ladder 7 is working, the battery modules and the slag materials after degumming fall from the discharge port 41 of the spray cabin to the feed hopper 21 on the transmission ladder, and are transported to the front end of the screening cabin 8 along the direction of the conveyor belt 22 .
[0086] When the screening cabin 8 is working, the degummed battery modules and crushed slag materials fall into the screening cabin 8 through the screening screen feed port 65, and the surface of the degummed battery module is swept by the induced draft duct 73 and the hot air blower 74, and the residual medicine on the surface of the battery module is dried and blown away, and the gas containing the medicine is sucked away by the air flow classifier 68. The screening screen motor 70 drives the screen 66 and the slag plate 67 to vibrate through reciprocating motion, drives the battery module and crushed slag mixture to move from the front end of the screen, and screens the degummed battery module and slag materials through the small holes of the screen.
