[0039] It should be noted that the bottom of the appearance detector 2 is the inspection station, and the opposite side of the appearance detector 2 is the loading station, such as ( Figure 1 ) The work station disc 3 shown in the figure rotates counterclockwise, and after passing the inspection station, it first arrives at the cleaning station, then the inspection station, and finally the unloading station.

[0040] Through the arrangement of the above structure, first at the loading station, the battery cell to be tested is placed on the flip plate 5 in the detection box 4 through a mechanical disk or manually, and the servo motor 61 is turned on. Through the meshing transmission of the driving gear 62, the reduction gear 63 and the driving gear plate 6, the station disk 3 will be driven to rotate counterclockwise. At this time, the battery cell to be tested will pass through each station in turn, and finally the battery cell to be tested will be moved to the unloading station, and then taken out by a mechanical arm or manually, and the above four stations can perform cyclic detection operations at the same time, thereby effectively improving the detection efficiency.

[0041] Reference Figure 2-Figure 4 The flipping mechanism includes a flipping plate 5, which is rotatably connected to the detection box 4.

At this time, the height of the flip plate 5 close to the positioning block 44 will be lower than the other side, and the battery cell to be tested will roll along the flip plate 5 to the lower side under the action of gravity. In this way, when the detection box 4 passes the detection station, the battery cell to be tested can be rolled and flipped, thereby realizing a comprehensive detection of the battery cell to be tested, effectively improving the detection efficiency, and relying on its own rolling and flipping, without adding other forces, it can minimize the damage to the battery cell to be tested caused by friction and the like, and improve the protection effect of the battery cell to be tested during the detection process. In addition, during the detection process, the directional airflow continues to act, which can clean the blocking surface at the bottom of the battery cell to be tested, further ensuring the accuracy of the detection result.

[0044] Through the arrangement of the above structure, when the servo motor 61 rotates, the driven shaft 74 and the air guide blade 741 will be driven to rotate rapidly in the air guide box 7 through the pulley group 64, so that a pressure difference is generated between the upper and lower parts of the air guide blade 741, so that the airflow at the top of the air guide box 7 moves to the bottom. At this time, the airflow at the air inlet groove 41 will be sucked into the top of the air guide box 7 along the first air groove 31, the first through groove 711 and the air inlet pipe 72, and then pushed to the bottom of the air guide box 7, while the airflow at the bottom of the air guide box 7 will enter the air outlet pipe 73, and blow from the air guide hole 43 to the battery cell to be tested along the second through groove 712, the second air groove 32 and the air outlet groove 42, while the air guide hole on the other side 43 will continue to suck this part of the airflow into the air guide box 7, at this time forming a directional circulating airflow, so as to take away the dust attached to the surface of the battery cell to be tested, effectively improving the cleanliness of the surface of the battery cell to be tested, and thus improving the accuracy of the detection; and when the detection box 4 moves to the bottom of the appearance detector 2, since the air flow speed in the detection box 4 is relatively fast, according to the Bernoulli principle, the airflow with a slower flow rate around the detection end of the appearance detector 2 will move into the detection box 4 with a faster air flow rate, so as to effectively avoid dust from adhering to the detection end of the appearance detector 2, effectively improve the clarity of the detection end of the appearance detector 2, thereby further improving the accuracy of the detection.

At this time, the flip plate 5 close to the positioning block 44 is higher, so the battery cell to be tested will stay on the lower side of the flip plate 5, and then the servo motor 61 is turned on, and the meshing transmission of the driving gear 62, the reduction gear 63 and the driving gear plate 6 will drive the station disk 3 to rotate counterclockwise. At this time, the detection box 4 at the loading station will move to the detection station through the cleaning station, and when the servo motor 61 rotates, it will pass through the leather The pulley assembly 64 drives the driven shaft 74 and the air guide blade 741 to rotate rapidly in the air guide box 7, so that a pressure difference is generated between the upper and lower parts of the air guide blade 741, so that the airflow at the top of the air guide box 7 moves to the bottom. At this time, the airflow at the air inlet groove 41 will be sucked into the top of the air guide box 7 along the first air groove 31, the first through groove 711 and the air inlet pipe 72, and then pushed to the bottom of the air guide box 7, while the airflow at the bottom of the air guide box 7 will enter the air outlet pipe 73, and blow along the second through groove 712, the second air groove 32 and the air outlet groove 42 from the air guide hole 43 to the battery cell to be tested, while the airflow at the other side The air guide hole 43 will continue to draw this part of the airflow into the air guide box 7, and at this time a directional circulating airflow will be formed, so as to take away the dust attached to the surface of the battery cell to be tested, effectively improving the cleanliness of the surface of the battery cell to be tested, and thus improving the accuracy of the detection; and the above-mentioned circulating airflow will pass through the filter disk 81 in the filter box 8, and then enter the subsequent recycling use after being filtered, effectively reducing the dust content in the detection area, improving the detection effect, and at the same time avoiding the dust carried in the airflow from causing wear to the battery cell to be tested; and when the station disk 3 rotates When the filter disc 81 is rotated continuously, the friction between the linkage ring 33 and the filter disc 81 is utilized to drive the filter disc 81 to rotate continuously, thereby continuously switching the filter surface, and effectively improving the filtering effect; and in the process of the rotation of the pulley group 64, the repulsive effect between the strong magnetic plate 94 and the piston plate 92 is utilized to push the piston plate 92 to move toward the side of the compressed second spring 93, so that the airflow in the piston box 91 is compressed and transported to the filter box 8 along the backblowing pipe 9, so that the rotating filter disc 81 is backblown and cleaned from both sides, which effectively improves the use effect of the filter disc 81.
