[0031] In the embodiment, the top end of the base 11 is provided with a base mounting hole, the base mounting hole is located at the periphery of the rotary bearing 131, and one end of the drive shaft 133 is rotatably arranged in the base mounting hole through a rotating bearing.

[0032] The barcode positioning mechanism 14 comprises a ring-shaped barcode strip (not shown in the figure) and a barcode scanner 141. The top end of the rotating plate 12 is provided with a ring-shaped barcode plate 121, which is close to the outer circumferential surface of the rotating plate 12 and the center of the barcode plate 121 and the center of the rotating plate 12 are located on the same vertical line. In actual application, the column is located on the inner side of the barcode plate 121. The barcode strip is arranged on the outer circumferential surface of the barcode plate 121 by adhesion. A plurality of barcodes are arranged on the barcode strip in the circumferential direction. The number of barcodes can be set according to actual conditions. The barcode scanner 141 is located on the periphery of the rotating plate 12 and is arranged on the top end of the base 11 through a support 1411. Specifically, the support 1411 is located on the periphery of the rotating plate 12. The bottom end of the support 1411 is arranged on the top end of the base. The barcode scanner 141 is arranged on the side close to the rotating plate 12 of the support 1411 and is close to the top end of the support 1411. The positions of the barcode scanner 141 and the support 1411 on the base 11 can be set according to actual conditions. The barcode scanner 141 is opposite to the barcode strip and is used to read the barcodes on the barcode strip. The rotation of the rotating plate 12 can drive the barcode plate 121 to rotate, thereby driving the barcode strip and the plurality of barcodes to rotate. Each barcode corresponds to an angle. Assuming that the barcode scanner 141 corresponds to the first barcode in the initial position, when it is needed to rotate the rotating plate 12 to a predetermined angle, for example, in the clockwise direction, the rotating plate 12, the barcode strip and the plurality of barcodes are first driven to rotate, for example, in the clockwise direction by the rotating motor 134. When the barcode corresponding to the predetermined angle is read by the barcode scanner 141, it indicates that the rotating plate 12 has been rotated to the predetermined angle. At this time, the barcode scanner 141 outputs a signal to the control system. The rotating motor 134 is stopped by the control system, thereby stopping the rotation of the rotating plate 12. Thus, the rotating plate 12 is accurately stopped at the predetermined angle. Therefore, the angle of the rotating plate 12 can be accurately controlled, thereby accurately controlling the angle of the loading platform device. The position of the loading platform device will not deviate, thereby improving the accuracy of the pick-and-place clamp and the power battery fixed on the clamp.

[0033] The brake mechanism 15 is used to clamp the rotating plate 111 after the rotating plate 111 stops rotating. Because there is a gear gap between the driving gear 132 and the outer ring 1311 of the slewing bearing 131, the rotating plate 12 will usually shake after the rotating motor 134 stops working, thereby causing the column and the loading platform device 30 to shake. The brake mechanism 15 clamps the rotating plate 12 after the rotating plate 12 stops rotating, thereby avoiding the shaking of the rotating plate 12, the column and the loading platform device 30, and improving the stability of the loading platform device 30 in picking and placing the clamp and the power battery fixed on the clamp. In the embodiment, the brake mechanism 15 is two. The rotating motor 134 is located between the two brake mechanisms 15. It can be understood that the number of brake mechanisms 15 can be set according to actual conditions.

[0034] Specifically, the brake mechanism 15 comprises a mounting seat 151 located at the periphery of the rotating plate 12, a brake driving member 152, and two clamping jaws 153 arranged oppositely in an up-down direction. The mounting seat 151 is arranged at the top end of the base 11. In the embodiment, the top end of the base 11 is provided with a mounting groove, and the mounting seat 151 is arranged at the bottom of the mounting groove. One end of the mounting seat 151 extends away from the rotating plate 12, and the other end of the mounting seat 151 is close to the rotating plate 12. The brake driving member 152 is arranged at the top end of the mounting seat 151 and close to one end of the mounting seat 151 through a driving member mounting plate 1521. The top end of the mounting seat 151 is provided with two mounting plates 1511 arranged oppositely. The two clamping jaws 153 are located between the two mounting plates 1511 and are hinged through a hinge shaft 154. The hinge shaft 154 is rotatably arranged between the two mounting plates 1511. In the embodiment, the side close to the two mounting plates 1511 is respectively provided with two mounting holes, and the two ends of the hinge shaft 154 are rotatably arranged in the two mounting holes and protrude from the side away from the two mounting plates 1511. The mounting ends of the two clamping jaws 153 are connected with the output end of the brake driving member 152 through two hinges 155. The clamping ends of the two clamping jaws 153 are located outside the bar code plate 121 and above and below the rotating plate 12, respectively. The brake driving member 152 is used to drive the two hinges 155 to move towards or away from the rotating plate 12, so as to drive the mounting ends of the two clamping jaws 153 to move away from or close to each other, and thus drive the clamping ends of the two clamping jaws 153 to move close to or away from each other to clamp or release the rotating plate 12.

[0035] In actual application, after the rotating plate 12 stops rotating, the two hinges 155 are driven by the brake driving member 152 to move towards the rotating plate 12, so as to drive the mounting ends of the two clamping jaws 153 to move away from each other, and thus drive the clamping ends of the two clamping jaws 153 to move close to each other to clamp the rotating plate 12. When the rotating plate 12 needs to rotate, the two hinges 155 are first driven by the brake driving member 152 to move away from the rotating plate 12, so as to drive the mounting ends of the two clamping jaws 153 to move close to each other, and thus drive the clamping ends of the two clamping jaws 153 to move away from each other to release the rotating plate 12. Then, the rotating plate 12 can be driven to rotate by the rotating motor 134.

[0036] In the embodiment, the brake driving member 152 is a cylinder, and it can be understood that the brake driving member 152 can also be other, for example, a hydraulic cylinder, etc., and a linear module, etc. can also be used. Two brake baffles 1513 are arranged between the two mounting plates 1511 and the driving member mounting plate 1521, and the two brake baffles 1513 are arranged at the top end of the mounting seat 151. The hinged shaft 154, the two hinges 155, the output end of the brake driving member 152 and the two clamping jaws 153 are partially accommodated in the brake protection cover 1512. The bottom end of the brake protection cover 1512 and the end close to the rotating plate 12 are both open. The brake protection cover 1512 is arranged on the two brake baffles 1513 and the two mounting plates 1511. The brake protection cover 1512 arranged can protect the hinged shaft 154, the two hinges 155 and the two clamping jaws 153.

[0037] The top end and the bottom end of the rotating plate 12 are respectively provided with two annular pads 122. The bar code plate 121 is located on the inner side of the pad 122 and close to the inner peripheral surface of the pad 122. The outer peripheral surface of the pad 122 is flush with the outer peripheral surface of the rotating plate 12. The pad 122 corresponds to the clamping end of the clamping jaw 153. The clamping end of the two clamping jaws 153 close to each other is respectively provided with two clamping jaw buffer pads 1531. The two clamping jaw buffer pads 1531 correspond to the two pads 122 respectively. The material of the pad 122 and the clamping jaw buffer pad 1531 is the same, for example, rubber, silicone, etc. The two pads 122 and the two clamping jaw buffer pads 1531 arranged can play a buffering role, which can avoid clamping damage to the rotating plate 12.
