For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figures 1 to 5As shown, the appearance defect detection device of square batteries after encapsulation in this embodiment includes a detection platform 1. Two conveyor belts 2 in opposite directions are arranged on the surface of the detection platform 1. One of the two conveyor belts 2 moves toward the rear direction of the detection platform 1, and the other moves toward the front direction of the detection platform 1 in opposite directions. A first top plate 4 is installed above the detection platform 1 through two supporting plates. A scanner 3 is arranged at the lower end of the first top plate 4. A scanner 3 is arranged on the left and right side walls inside the detection platform 1. The three scanners 3 are located above and on the left and right sides of the conveyor belt 2. Since the scanner 3 is a divergent scanning structure, it can fully scan the five surfaces of the front and back ends, left and right ends and the upper end of the battery on the surface of the conveyor belt 2. A longitudinal moving block 12 is installed on the surface of the left end side wall of the rear of the detection platform 1. The longitudinal moving block 12 can move in the vertical direction. A driving device 11 is installed at the right end of the longitudinal moving block 12, and a first telescopic rod 9 is installed at the right end of the driving device 11. The driving device 11 and the first telescopic rod 9 can follow the longitudinal moving block 12 to perform synchronous vertical movement. Two clamping arc plates 6 are symmetrically installed at the front end of the first telescopic rod 9. The two clamping arc plates 6 can clamp the battery. A connecting rod 10 is sleeved on the surface of the first telescopic rod 9 through a through hole 15. It should be noted that the connecting rod 10 is a driven telescopic rod, which can be retracted and extended in the vertical direction under the action of external force. The driving device 11 is a servo motor, which can drive the first telescopic rod 9 to rotate inside the through hole 15. A lateral moving block 7 is installed on the upper end of the connecting rod 10. The lateral moving block 7 can drive the connecting rod 10 to move in the horizontal direction. At the same time, the connecting rod 10 can support the first telescopic rod 9.

[0023] Specifically, two fixed blocks 18 are symmetrically installed on the surface of the first telescopic rod 9 at the right end of the connecting rod 10, and a second telescopic rod 19 is installed at the front end of the two fixed blocks 18. The right ends of the two second telescopic rods 19 are respectively connected to the two clamping arc plates 6. The two second telescopic rods 19 and the first telescopic rod 9 are both electric telescopic rods. When the two electric telescopic rods 19 retract toward the direction of the fixed block 18, the two clamping arc plates 6 will be driven to open outwards. When the two electric telescopic rods 19 extend outwards, the two clamping arc plates 6 will be driven to clamp.

[0024] Furthermore, a second groove 13 is opened at the lower end of the second top plate 5, and a first threaded rod 14 is installed inside the second groove 13. The first threaded rod 14 is threadedly connected to the transverse moving block 7 through the slider, and one end of the first threaded rod 14 is connected to a driving motor, which can drive the first threaded rod 14 to rotate. When the first threaded rod 14 rotates, the transverse moving block 7 will move along the length direction of the first threaded rod 14. At this time, the connecting rod 10 will move synchronously with the transverse moving block 7. When the first telescopic rod 9 starts to move, the transverse moving block 7 will move synchronously under the control of the system, and the connecting rod 10 is always kept in the front position of the first telescopic rod 9 to provide support for the first telescopic rod 9.

[0025] Furthermore, two first grooves 8 are symmetrically provided on the surface of the left end side wall of the detection platform 1, and a second threaded rod 16 is rotatably connected inside one of the first grooves 8. The second threaded rod 16 is threadedly connected to the longitudinal moving block 12 through a slider, and a driving motor is connected to the lower end of the second threaded rod 16. The driving motor drives the second threaded rod 16 to rotate, and the second threaded rod 16 can drive the longitudinal moving block 12 to move along the length direction of the second threaded rod 16.

[0026] Furthermore, a guide rod 17 is installed inside another first groove 8, and the guide rod 17 is slidably connected to the longitudinal moving block 12 through the slider. The guide rod 17 is slidably connected to the longitudinal moving block 12 through the slider, and can provide guidance and limitation for the longitudinal moving block 12 when it moves.

[0027] Furthermore, the three scanners 3 are electrically connected to an external computer. After scanning a battery multiple times, the three scanners 3 will store and transmit the scanned images to the external computer, and the user can observe them in real time to detect whether there are defects on the outer wall of the battery.

[0028] The method of use of this embodiment is as follows: by placing the battery on the surface of a conveyor belt 2, the conveyor belt 2 drives the battery to move to the rear of the inspection platform 1, and after passing through the scanners 3 on the top, left and right, the scanner 3 will store and upload the scanned image. When the battery moves to the end of the conveyor belt 2, the transverse moving block 7 drives the first telescopic rod 9 and the two clamping arc plates 6 to move transversely to the top of the battery, the longitudinal moving block 12 drives the clamping arc plates 6 to descend, and opens the two clamping arc plates 6, and clamps the battery through the two clamping arc plates 6. The driving device 11 drives the first telescopic rod 9 to rotate 180 degrees inside the through hole 15, so that the battery is turned over, and drives the clamping arc plates 6 and the battery to move to the top of another conveyor belt 2 through the transverse moving block 7, opens the clamping arc plates 6 to allow the battery to enter the conveyor belt 2, and moves in the opposite direction, so that the battery is scanned again by the three scanners 3, and then the scanned images of all sides of the battery are obtained, and there is no need to manually pick up and turn over the battery. After the battery is placed in the inspection platform 1, it can be fully automatically transmitted and scanned, which is convenient and fast, and greatly liberates labor costs.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents.
