[0038] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below according to specific implementation methods and in combination with the accompanying drawings.

[0039] Figure 1 The schematic diagram of the structure of the automatic detection device for battery cells provided in the embodiment of the present application. The device comprises a frame 1 and two sets of independent detection units arranged on the frame 1. Each set of detection units can automatically detect the battery cells to be detected.

[0040] For details, see Figure 2 A workbench 2 is provided in the frame 1. Two groups of detection units are symmetrically arranged on the left and right sides of the workbench 2. Each group of detection units includes a detection mechanism and a conveying mechanism. The detection mechanism includes a first detection component for detecting the bottom surface of the battery cell and a second detection component for performing pressure detection on the battery cell. The conveying mechanism is used to convey the battery cell to be detected, and when the conveying mechanism drives the battery cell to move, the moving path of the battery cell passes through the detection areas of the first detection component and the second detection component in sequence.

[0041] See also Figure 2 and Figure 3 The transport mechanism includes a first transport assembly. The first transport assembly includes a first slide rail 3 fixedly mounted on the workbench 2. The first slide rail 3 is located on one side of the second detection assembly, and the first slide rail 3 extends along the width direction of the workbench 2. A first slider 4 is slidably mounted on the first slide rail 3, and the first slider 4 moves along the first slide rail 3 under the drive of the first sliding drive member. A pressure detection platform 5 matched with the second detection assembly is fixedly mounted on the first slider 4, and a pressure sensor for detecting a pressure value is arranged in the pressure detection platform 5.

[0042] When performing pressure testing on a battery cell, the battery cell to be tested is placed on the pressure testing platform 5. Then, pressure is applied to the battery cell by the second testing component to complete the pressure testing of the battery cell.

[0043] Preferably, in order to ensure the position stability of the battery cell on the pressure detection platform 5, a plurality of pneumatic suction nozzles 6 for adsorbing the battery cell are provided on the pressure detection platform 5, see Figure 3 .

[0044] See also Figure 2~Figure 4 The second detection component includes a column 7 fixedly mounted on the workbench 2. The column 7 is located on one side of the first slide rail 3. A mounting seat 9 is fixedly arranged at the upper end of the column 7. A fixed pulley assembly 10 is fixedly mounted on the mounting seat 9. A rope body 11 is wound around the upper half of the fixed pulley assembly 10, and one end of the rope body 11 is connected to the pressure block 8, and the other end is connected to a winding device 12 arranged on the mounting seat 9. The fixed pulley assembly 10 includes two fixed pulleys arranged in sequence along the length direction of the mounting seat 9. The distance between the pressure block 8 and the winding device 12 is pulled apart by these two fixed pulleys, and the pressure block 8 is in a naturally drooping state.

[0045] It should be noted that when the first slider 4 moves to a certain position along the first slide rail 3, the pressure detection platform 5 is located directly below the pressure block 8. At this time, the rope body 11 is controlled by the winding device 12, so that the pressure block 8 can move downward under its own weight and press on the battery cell to be detected by its own weight. At this time, the pressure value can be detected by the pressure sensor.

[0046] In this embodiment, the winding device 12 can be driven by a rotary motor.

[0047] See also Figure 5 , the conveying mechanism also includes a second conveying assembly. The second conveying assembly includes a top plate 13 fixedly mounted on the workbench 2, and the top plate 13 is supported by a plurality of vertical frames fixedly mounted on the workbench 2, so that the top plate 13 is located above the first slide rail 3. A second slide rail 14 is fixedly mounted at the lower end of the first top plate 13. The extension direction of the second slide rail 14 is parallel to the extension direction of the first slide rail 3, and the second slide rail 14 is located directly above the first slide rail 3. A second slider 15 is slidably mounted on the second slide rail 14. A first pneumatic suction cup assembly 16 for adsorbing battery cells and a second lifting drive device for driving the first pneumatic suction cup assembly 16 to rise and fall are provided on the second slider 15.

[0048] Among them, see Figure 6~Figure 9The second lifting drive device includes a mounting plate 17 fixedly mounted on the lower end of the second slider 15, and a third slide rail 18 extending in the vertical direction is fixedly mounted on the mounting plate 17. A lifting plate 19 is slidably mounted on the third slide rail 18, and the lifting plate 19 is driven to lift by a first lifting cylinder 20 fixedly mounted on the lower end of the second slider 15. An L-shaped connecting plate 31 is fixedly mounted on the side wall at the lower end of the lifting plate 19, and a buffer is arranged at the bottom of the L-shaped connecting plate 31. Fig.10 The buffer member includes an L-shaped block 32, a buffer slider 33 is disposed on one side of the L-shaped block 32, and a buffer spring column 35 is disposed on the top of the buffer slider 33. A first pneumatic suction cup assembly 16 for adsorbing the battery sheet is disposed at the bottom of the buffer slider 33.

[0049] When the first lifting cylinder 20 drives the lifting plate 19 to descend, it can drive the first pneumatic suction cup assembly 16 to descend synchronously, so as to adsorb the battery cell to be detected and rise synchronously with the first pneumatic suction cup assembly 16. The buffer slider 33 cooperates with the buffer spring column to buffer the lifting plate 19 when the lifting movement of the lifting plate 19 stops, absorbs the inertia of the lifting plate 19 and other components, and thus prevents the first pneumatic suction cup assembly 16 from shaking and causing the battery cell to fall off or shift in position.

[0050] Preferably, a limit sensor 36 is also fixedly mounted on the lifting plate 19, which can generate a limit signal when the lifting plate moves to the limit position.

[0051] See also Figure 3 The first detection component includes a first infrared laser sensor 21 fixedly mounted on the workbench 2, and the first infrared laser sensor 21 is located at one end of the first slide rail 3 adjacent to the second slide rail 14. The first infrared laser sensor 21 is used to detect the bottom surface of the battery cell. At the same time, the first detection component also includes a second infrared laser sensor 22 fixedly mounted on the first slider 4. The second infrared laser sensor 22 is located on the side of the first slider 4 adjacent to the first infrared laser sensor 21. The second infrared laser sensor 22 is used to detect the explosion-proof valve area on the bottom surface of the battery cell. See the schematic diagram of the battery cell Fig.12 .

[0052] The first lifting cylinder 20 drives the first pneumatic suction cup assembly 16 to descend, and after the battery cell to be tested is adsorbed, the first pneumatic suction cup assembly 16 is driven to rise, and the second slider 15 drives the first pneumatic suction cup assembly 16 to move synchronously with the battery cell along the second slide rail 14 until the battery cell is located directly above the pressure testing platform 5. In this process, the battery cell passes through the detection area of ​​the first infrared laser sensor 21 and the second infrared laser sensor 22 in sequence, so that the first detection assembly completes the detection of the battery cell. After that, the first lifting cylinder 20 drives the first pneumatic suction cup assembly 16 to descend until the battery cell is located on the pressure testing platform 5. At this time, the first pneumatic suction cup assembly 16 stops adsorbing the battery cell, and the pneumatic suction nozzle 6 on the pressure testing platform 5 adsorbs the battery cell, so that the battery cell can be fixed on the pressure testing platform 5. After that, the first slider 4 moves on the first slide rail 3, so that the pressure testing platform 5 can be located directly below the pressure block 8. At this time, the rope body 11 is controlled by the winding device 12, so that the pressing block 8 can move downward under its own weight and press on the battery cell to be tested by its own weight. At this time, the pressure value is detected by the pressure sensor, so that the second detection component completes the pressure detection of the battery cell.

[0053] See also Fig.11 , each detection unit also includes a flipping mechanism. The flipping mechanism includes a flipping seat 23 fixedly mounted on the workbench 2, the flipping seat 23 and the second detection assembly are located on the same side of the first slide rail 3, and the flipping seat 23 is located on the side of the column 7 away from the first infrared laser sensor 21. A lifting seat 24 is slidably arranged on the flipping seat 23, and the lifting seat 24 is lifted and lowered in the vertical direction under the drive of the second lifting cylinder 25. A second pneumatic suction cup assembly 26 for adsorbing battery cells is arranged on the lifting seat 24. The second pneumatic suction cup assembly 26 is driven to flip by a flipping motor 27 fixedly mounted in the lifting seat 24.

[0054] After completing the pressure test on the battery cell, the second slider 15 drives the battery cell to move synchronously with the pressure test platform 5 to the bottom of the second pneumatic suction cup assembly 26. Then the second lifting cylinder 25 drives the lifting seat 24 to descend until the second pneumatic suction cup assembly 26 contacts the upper end surface of the battery cell. At this time, the pneumatic suction nozzle 6 in the pressure test platform 5 is controlled to stop running, and the second pneumatic suction cup assembly 26 is operated, so that the battery cell can be adsorbed on the second pneumatic suction cup assembly 26. After that, after the second lifting cylinder 25 drives the lifting seat 24 to rise, the second pneumatic suction cup assembly 26 can be driven by the flip motor 27 to drive the battery cell to flip 180°, so as to facilitate the subsequent unloading of the battery cell.

[0055] See also Figure 2, a workpiece conveying mechanism is also provided on the workbench 2. The workpiece conveying mechanism includes three conveyor belts located at one end of the two first slide rails 3 away from the first infrared laser sensor 21. The three conveyor belts include two first conveyor belts 28 for conveying unqualified battery cells for inspection and one second conveyor belt 29 for conveying sampled battery cells. The conveying directions of the first conveyor belt 28 and the second conveyor belt 29 are both perpendicular to the extension direction of the first slide rail 3, and the conveying direction of the second conveyor belt 29 is opposite to that of the first conveyor belt 28. A first collecting bin for collecting unqualified battery cells for inspection is provided at the front end of the conveying direction of the first conveyor belt 28.

[0056] In addition, the battery cell automatic inspection device also includes a manipulator assembly 30. The manipulator assembly 30 is used to transport the battery cells that have completed the inspection and have been flipped by the flipping mechanism to the unloading area 34. At the same time, the manipulator assembly 30 is also used to transport the battery cells that have failed the inspection to the first conveyor belt 28, and place the sampled battery cells on the second conveyor belt 29.

[0057] Therefore, the technical solution of the present application not only automates the entire detection process, greatly improves the detection efficiency, reduces the labor intensity of operators, but also ensures the detection accuracy of the battery cells.
