The output end of the longitudinal driving mechanism 61 is connected with the vertical driving mechanism 62, and the output end of the vertical driving mechanism 62 is connected with the suction disc mechanism 63. The suction disc mechanism 63 is used for sucking the soft package lithium battery 200. The longitudinal driving mechanism 61 and the vertical driving mechanism 62 are both driven by the movement of a screw rod and a nut driven by a motor. The suction disc mechanism 63 is used for sucking the soft package lithium battery 200 by setting a suction disc on the arm and using the negative pressure of the suction disc to suck the surface of the soft package lithium battery 200.

[0027] Referring to Figure 1 and Figure 7 The soft package lithium battery appearance detection mechanism 100 further comprises a position adjusting mechanism 9 arranged on both sides of the conveying belt 7 to position the soft package lithium battery 200 before detection by the fourth detection camera 5. Since the soft package lithium battery 200 may be displaced during the process of being transferred from the moving platform 1 to the conveying belt 7 and moving along with the conveying belt 7, the position adjusting mechanism 9 is arranged to quickly and accurately position the soft package lithium battery 200 before detection by the fourth detection camera 5, thereby ensuring the accuracy of detection by the fourth detection camera 5.

By arranging the adjusting mechanisms 91, the soft package lithium battery 200 is positioned in the middle direction by the pushing of the adjusting mechanisms 91, thereby ensuring the accurate positioning of the soft package lithium battery 200 and further improving the detection efficiency without manual positioning.

[0028] In combination with the drawings, the working principle of the soft package lithium battery appearance detection mechanism 100 is described in detail as follows:

[0029] In operation, the soft package lithium battery 200 is first placed on the moving platform 1, and then the moving platform 1 moves laterally through the detection interval between the two first detection cameras 2, during which the two first detection cameras 2 are activated to take photos of the two opposite short sides of the soft package lithium battery 200. Then, the moving platform 1 moves longitudinally through the detection interval between the two second detection cameras 3, during which the two second detection cameras 3 are activated to take photos of the two opposite long sides of the soft package lithium battery 200. After that, the vertical driving mechanism 62 of the transfer robot 6 drives the suction disc mechanism 63 to suck the soft package lithium battery 200 on the moving platform 1, and then lifts the soft package lithium battery 200 away from the moving platform 1. Then, the longitudinal driving mechanism 61 of the transfer robot 6 drives the soft package lithium battery 200 to move longitudinally from the moving platform 1 to the conveying belt 7, during which the soft package lithium battery 200 passes through the gap 101, and the third detection camera 4 takes a photo of the lower bottom surface of the soft package lithium battery 200. Next, the transfer robot 6 places the soft package lithium battery 200 on the conveying belt 7, and the conveying belt 7 drives the soft package lithium battery 200 to move forward by one step longitudinally, and the distance of one step of the conveying belt 7 is the length of the soft package lithium battery 200. After that, the translation driving mechanism 8 drives the fourth detection camera 5 to move longitudinally and take a photo of the upper surface of the soft package lithium battery 200. Finally, the conveying belt 7 drives the soft package lithium battery 200 to move to the unloading position. When it is detected that at least one side of the soft package lithium battery 200 has a defect, the soft package lithium battery 200 with the defect can be removed by a unloading robot arranged on one side of the conveying belt 7 during the unloading process of the conveying belt 7.

[0030] Compared with the prior art, since the application sets a pair of first detection cameras 2 and a pair of second detection cameras 3, sets the first detection cameras 2 longitudinally, sets the second detection cameras 3 transversely, sets a moving platform 1, and makes the moving platform 1 move transversely and longitudinally, carries the soft pack lithium battery 200 on the moving platform 1, drives the soft pack lithium battery 200 to move transversely or longitudally by the moving platform 1, and makes the soft pack lithium battery 200 pass through the detection intervals of the two first detection cameras 2 and the detection intervals of the two second detection cameras 3, the purpose of appearance detection of the short and small side and the long and small side of the soft pack lithium battery 200 is achieved. In addition, the third detection camera 4 is set below the gap between the moving platform 1 and the conveying belt 7, so that the lower bottom surface of the soft pack lithium battery 200 is appearance detected in the process of transferring the soft pack lithium battery 200 from the moving platform 1 to the conveying belt 7 by the transfer robot 6. Finally, the fourth detection camera 5 is set above the conveying belt 7 to appearance detect the upper surface of the soft pack lithium battery 200; therefore, the six sides of the soft pack lithium battery 200 can be automatically appearance detected, manual visual detection is not needed, the labor intensity of workers is greatly reduced, the detection efficiency is improved, the wrong, missing and misjudgment of manual detection is effectively avoided, and the detection quality is high.

[0031] The structure and detection principle of the detection camera involved in the soft pack lithium battery appearance detection mechanism 100 are well known to those skilled in the art, and will not be described in detail here.

[0032] The above disclosure is only a preferred embodiment of the application, and of course cannot limit the scope of the right of the application, so the equivalent changes made in the patent range of the application still belong to the scope covered by the application.
