A code scanning gun 31 is installed above the conveying assembly 2, and a weighing assembly 32 is installed below the conveying assembly 2, forming a detection station 3 between the code scanning gun 31 and the weighing assembly 32. The weighing assembly 32 is used to weigh the battery at the detection station 3, and the code scanning gun 31 is used to scan the code of the battery at the detection station 3. A baffle 4 is movably arranged above the conveying assembly 2, and is used to stop the battery at the detection station 3. A driving assembly 5 is installed on the base 1, and is used to move the baffle 4 in the width direction of the base 1. An adjusting assembly 6 is installed between the base 1 and the driving assembly 5, and is used to move the driving assembly 5 in the length direction of the base 1. According to the size of the batch of batteries, the driving assembly 5 is moved in the length direction of the base 1 by the adjusting assembly 6, so that the driving assembly 5 drives the baffle 4 to move in the length direction of the base 1. When the baffle 4 stops the battery at the detection station 3, the center of gravity of the battery is located at the center of the weighing assembly. When the battery is output by the upstream process, the battery is first moved to the detection station 3 by the conveying assembly 2. When the battery moves to the detection station 3, the baffle 4 is moved by the driving assembly 5 to stop the battery at the detection station 3. Then, the weighing assembly 32 weighs the battery on the conveying assembly 2, and the code scanning gun 31 scans the code of the battery on the conveying assembly 2.

When the weighing sensor 323 moves to contact the bottom of the receiving seat 72, the weighing sensor 323 detects the weight of the receiving seat 72, the receiving support 71 and the receiving rod 7. Then the output shaft of the weighing piston cylinder 321 continues to elongate until the receiving rod 7 separates the battery from the roller 23, and the weighing sensor 323 detects the weight of the receiving seat 72, the receiving support 71, the receiving rod 7 and the battery, so that the weight of the battery is obtained by using the weight difference of twice.

[0039] The implementation principle of the battery code scanning and weighing device is as follows: when the battery is output by the upstream process, the battery moves to the detection station 3 through the conveying assembly 2. When the battery moves to the detection station 3, the driving piston cylinder 51 drives the baffle 4 to move and stop the battery on the detection station 3.
