[0002] In the traditional battery cell production process, obtaining samples for quality testing usually requires too much manpower and time. Furthermore, the accuracy of test data can be affected by the external environment and different testing methods used by different testers during the transfer of the slurry. It is also possible to obtain the specific state of the slurry at any time under different standing times.

[0003] Therefore, we need to design an integrated material feeding and testing device to solve these problems. Utility Model Content

[0004] The problem to be solved by this utility model is to provide an integrated material feeding and testing device.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An integrated feeding and testing device includes a storage tank, a feeding transfer tank, and a testing transfer tank.

[0008] The output end of the feeding transfer tank is also equipped with a second filter, the filter screen of which is between 140 and 160 mesh, and a first feeding valve is provided between the second filter and the feeding transfer tank.

[0009] This setup ensures a continuous output of slurry through the feed pump and the level gauge on the feed transfer tank. Filters of different mesh sizes can filter the slurry multiple times, improving its quality.

[0010] Preferably, the detection device includes a viscosity meter, a solid content meter, a resistance meter, and a fineness meter, and an exhaust device is also connected to the solid content meter.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-2As shown, an integrated feeding and testing device includes a storage tank 1, a feeding transfer tank 10, and a testing transfer tank 5. Both the feeding transfer tank 10 and the testing transfer tank 5 are connected to the storage tank 1. Each of the three tanks is equipped with a level monitoring device, which includes a first level gauge 4, a second level gauge 27, and a third level gauge 28. The first level gauge 4 is installed on the storage tank 1 and is used to monitor the level of the slurry within the storage tank 1, thereby monitoring the slurry capacity within the storage tank 1. The second level gauge 27 is installed on the feeding transfer tank 10, and the third level gauge 28 is installed on the detection transfer tank 5. A detection master control valve 4 is set between the detection transfer tank 5 and the storage tank 1. The output end of the detection transfer tank 5 is equipped with a discharge control device 25 and a detection device. The discharge control device 25 is located between the detection device and the detection transfer tank 5. A feeding pump 8 and a feeding master control valve 9 are set between the feeding transfer tank 10 and the storage tank 1. The feeding pump 8 is a diaphragm pump with a maximum operating pressure of 0.6 MPa to achieve stable and continuous feeding.

[0028] Specifically, a magnetic suction device 6 and a first filter 7 are installed between the feed pump 8 and the storage tank 1. A discharge control valve 3 is installed between the magnetic suction device 6 and the storage tank 1. The magnetic suction device 6 is used to remove iron impurities in the slurry, and the iron removal rate can reach 98%. The filter screen of the first filter 7 is between 120-130 mesh. The magnetic suction device 6 is located between the first filter 7 and the storage tank 1. The discharge control valve 9 is located between the feed pump 8 and the feed transfer tank 10. A second filter 12 is also installed at the output end of the feed transfer tank 10. The filter screen of the second filter 12 is between 140-160 mesh. A first feed valve 11 is installed between the second filter 12 and the feed transfer tank 10. The output end of the second filter 12 is connected to the coating machine trough 14. A second feed valve 13 is also installed between the second filter 12 and the coating machine trough 14.

[0029] Specifically, the testing device includes a viscosity meter 16, a solids content meter 18, a resistivity meter 22, and a fineness meter 24. An exhaust device 20 is also connected to the solids content meter 18. The exhaust device 20 can expel the gas inside the solids content meter 18, preventing moisture in the air from interfering with the detection and thus improving accuracy. It should be noted that, due to the fluidity of air, an exhaust valve 19 is also installed between the exhaust device 20 and the solids content meter 18. When open, it allows the gas inside the solids content meter 18 to escape; when closed, it prevents external gas from entering the solids content meter 18.

[0030] The following are used in this embodiment:

[0031] The viscosity meter 16 has a single sampling capacity of 200ml, the detection temperature needs to be controlled between 20℃ and 30℃, and the detection time is 30s.

[0032] The single sampling capacity of the solid content analyzer 18 needs to be greater than 1g, and the detection temperature needs to be controlled at 130℃, and the detection time is 300s.

[0033] The resistance detector 22 has a single sampling capacity of 100ml, the detection temperature needs to be controlled between 20℃ and 30℃, and the detection time is 30s.

[0034] The fineness tester 24 has a single sampling capacity of 0.2-0.4g, the detection temperature needs to be controlled between 20℃ and 30℃, and the detection time is 5 seconds.

[0035] To ensure more accurate test results from each testing instrument, a discharge control device 25 is installed between the testing transfer tank 5 and the testing equipment. This device includes a viscosity testing valve 15, a solid phase testing valve 17, an electrical property testing valve 21, and a particle size testing valve, all with quantitative output. The viscosity testing valve 15 and the electrical property testing valve 21 have flow control functions, enabling precise control of the output slurry volume. The solid phase testing valve 17 and the particle size testing valve have weight detection functions, enabling control of the output slurry weight. The viscosity testing valve 15 is located between the viscosity meter 16 and the testing transfer tank 5; the solid phase testing valve 17 is located between the solid content meter 18 and the testing transfer tank 5; the electrical property testing valve 21 is located between the resistance meter 22 and the testing transfer tank 5; and the particle size testing valve 23 is located between the fineness meter 24 and the testing transfer tank 5.

[0036] Viscosity detection valve 15 and electrical property detection valve 21 are flow control valves with a control range of 0-500ml, and solid phase detection valve 17 and particle size detection valve 23 are mass control valves with a control range of 0-10g.

[0037] It also includes a main control unit 29, which is electrically connected to the discharge control device, the main feed control valve 9, the feed pump 8, the detection device and the detection control valve 4.

[0038] Specifically, the discharge control valve 3, the first feeding valve 11, the second feeding valve 13, the magnetic suction device 6, and the vent valve 26 are also connected to the main control unit, while the main control unit 29 is also connected to the host computer via a network.

[0039] The working process of this embodiment is as follows: During operation, the main control unit 29 controls the opening of the discharge main control valve 3 and the detection main control valve 4, allowing the slurry in the storage tank 1 to flow into the detection transfer tank 5. When the third level gauge 28 on the detection transfer tank 5 detects that the liquid level meets the sampling requirements of all detection devices, it sends a signal to the main control unit 29. The main control unit 29 then controls the closing of the discharge main control valve 3 and the detection main control valve 4. Subsequently, the main control unit 29 controls the opening of the corresponding control valve on the discharge control device 25 to allow the slurry to flow in; that is, after the viscosity detection valve 15 is opened, the slurry will flow... When the slurry flowing through the viscosity tester 16 reaches 200ml, the viscosity tester 15 closes. After the electrical tester 21 opens, the slurry flows into the resistance tester 22. When the slurry flowing through the electrical tester 21 reaches 100ml, the electrical tester 21 closes. Similarly, the solid phase tester 17 controls the weight of the slurry entering the solid content analyzer 18 to be 1g, and the particle size tester 23 controls the weight of the slurry entering the fineness analyzer 24 to be between 0.2-0.4g, so that all testing equipment meets the sampling requirements for a single test.

[0040] After sampling, the viscosity analyzer 16 will test the sample and output the test result to the main control unit after 30 seconds; after sampling, the resistance analyzer 22 will complete the test in 300 seconds and output the test result to the main control unit. Similarly, after sampling, the solids content analyzer 18 will complete the test in 30 seconds and output the test result to the main control unit. After sampling, the fineness analyzer 24 will complete the test in 5 seconds and output the test result to the main control unit. After receiving the test results, the main control unit will compare them with the set threshold.

[0041] If the output results show that the slurry viscosity is between 4500 and 5500 cp, the drying rate is 50%, the resistance is between 700Ω and 100KΩ, and the particle size is between 5 and 10, it indicates that the slurry in storage tank 1 meets the requirements. Next, the main control unit 29 will control the discharge main control valve 3 and the supply main control valve 9 to open, and simultaneously control the diaphragm-type supply pump 8 to transport the slurry into the supply transfer tank 10. During this process, the magnetic suction device 6 will also start working under the control of the main control unit 29 to adsorb and remove iron impurities in the slurry. The first filter 7 will perform preliminary filtration of the slurry. After the slurry enters the supply transfer tank 10, the second level gauge 27 will monitor the slurry level. When the level meets the minimum height requirement, the main control unit 29 will control the first supply valve 11 and the second supply valve 13 to open, supplying the slurry into the coating machine's material tank 14. The system supplies materials and can adjust the flow rate of the slurry flowing into the coating machine trough 14 by controlling the first supply valve 11 and the second supply valve 13. During this process, the slurry is also filtered a second time by the second filter 12 to further remove impurities and improve the quality of the slurry. If the second level gauge 27 on the supply transfer tank 10 detects that the slurry level has reached the set maximum level height during the supply process, it will send a signal to the main control unit 29 again. The main control unit 29 will then control the supply pump 8 to reduce the output flow rate, and vice versa, it will control the supply pump 8 to increase the output flow rate to ensure stable slurry output.

[0042] If the output results do not meet the above requirements, the slurry in storage tank 1 needs to be remixed. At this time, the main control unit will send a signal to the host computer via the network. The host computer will adjust the slurry ratio in storage tank 1 according to the detection results fed back by the main control unit 29. After the adjustment is completed, the host computer will send a signal to the main control unit 29, and the main control unit 29 will detect the adjusted slurry. It should be noted that before re-detection, the main control unit 29 will first control the vent valve 26 to open, empty the residual slurry in the detection transfer tank 5, and then control the discharge main control valve 3 and the detection main control valve 4 to open, so that the slurry flows back into the detection transfer tank 5 for detection, which can ensure the accuracy of the detection results.

[0043] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
