[0049] The working process of the present invention is as follows:

[0050] Feeding stage

[0051] Battery feeding: The batteries enter horizontally and side by side through the feed port 211 of the upper feed box 21. The mobile hydraulic cylinder 214 adjusts the position of the side plate 213 as needed, thereby adjusting the width of the interior of the upper feed box 21 to accommodate batteries of different sizes and models. The batteries slide into the lower feed box 22 through the discharge port 212.

The batteries enter the inclined discharge plate 225 from the lower feed box 22 under the action of the discharge conveying mechanism 224, and then fall into the battery slot 33 of the conveying device 3 through the battery box 226.

[0052] Transportation and measurement preparation stage

[0053] Battery positioning: The battery is placed on a battery conveying block 32 provided with a battery slot 33, and the magnetic block 34 helps to fix the position of the battery to ensure that the battery maintains the correct position in the battery slot 33. The power motor 35 is started to drive the battery conveyor belt 31 to deliver the battery to the internal resistance measurement area. When the battery arrives at the measuring area, the pressing block 61 of the pressing block device 6 presses the battery downward to keep the battery stable and accurately positioned, ensuring good contact between the voltage and current needles 47 and the battery. The sliding frame 43 and the sliding rod 44 automatically adjust their positions according to the size of the battery to ensure that the voltage and current needles 47 correctly contact the measuring point of the battery. The inner measuring instrument 411 measures the internal resistance of the battery through the voltage and current needle 47. During this process, the buffer spring 46 and the spring 412 provide stable pressure and resilience to ensure the accuracy of the measurement.

[0054] Discharging stage

[0055] After the measurement is completed, the push hydraulic cylinder 52 is activated to push the ejector rod 53 to push the battery from the battery conveyor belt 31 to the discharge trough 51. According to the result of the internal resistance measurement, the battery can be guided to different discharge troughs 51 for classification or subsequent processing.
