One side of the withstand voltage detection device 5 is electrically connected to two terminal clamps 9 through a connecting wire.

[0029] With the above structure, batch detection of power batteries can be realized.

[0030] The above-mentioned withstand voltage detection device 5, servo electric cylinder 7 and detection probe 8 are all prior arts and will not be elaborated here.

[0031] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 , the profiling tooling 3 includes a plate frame 301, an insulating and pressure-resistant plate 302, a through groove 303, a roller 304, a driving motor 305, a fixing mechanism 306, a clamping box 307 and a plate groove 308. The insulating and pressure-resistant plate 302 is fixedly connected between the two plate frames 301, and the lower ends of the plate frames 301 are fixedly connected to the upper end of the cabinet 2.

[0032] A plurality of through grooves 303 are opened on the insulating and pressure-resistant plate 302. Below each through groove 303, there is a roller 304. The roller 304 is movably installed between the two plate frames 301, and the upper end of the roller 304 is flush with the insulating and pressure-resistant plate 302 inside the through groove 303.

[0033] On the rotating shaft on one side of the roller 304, a belt pulley 3041 is fixedly connected. A transmission belt 3042 is drivingly connected to the belt pulley 3041. The plurality of rollers 304 are drivingly connected through the belt pulley 3041 and the transmission belt 3042.

[0034] Under the action of belt drive, the driving motor 305 drives the rotation of the roller 304, so that the batteries can be transported and conveyed in the profiling tooling 3, which is convenient for batch detection of the batteries. There is no need for the detection personnel to frequently take the batteries for tooling detection, thereby improving the detection.

[0035] Please refer to Figure 4 , Figure 5 and Figure 6 , the rotating shaft of the rightmost roller 304 is fixedly connected to the output end of the driving motor 305. The driving motor 305 is fixedly installed on the front plate frame 301. Plate grooves 308 are opened on the inner side walls of the two plate frames 301, and a fixing mechanism 306 is arranged at the plate grooves 308.

[0036] The fixing mechanism 306 includes two cylinders 3061, a clamping plate 3062 and a rubber gasket 3063. The two cylinders 3061 are fixedly installed on the outer side wall of the plate frame 301. The telescopic rods of the two cylinders 3061 are fixedly connected to the clamping plate 3062. The clamping plate 3062 is arranged in the plate groove 308, and a rubber gasket 3063 is arranged on the contact surface of the clamping plate 3062.

[0037] Through the fixing mechanism 306 provided on the plate frame 301, the battery transported into the profiling tooling 3 can be clamped.

At the same time, because the rubber gasket 3063 has a certain flexibility, it will not cause wear to the paint layer of the battery and has a good protection effect.

[0038] The working principle and usage process of the present utility model: When in specific use, the power batteries to be detected are transported to the insulation pressure plate 302 of the profiling tooling 3 in batches through the left conveyor belt 4. Then, the two cylinders 3061 on the fixing mechanism 306 extend, pushing the clamping plate 3062 towards the battery core. Under the action of the two clamping plates 3062, the battery core on the insulation pressure plate 302 is clamped. Then, the end clamp 9 in the clamping box 307 is electrically connected to the terminal of the battery, and the servo electric cylinder 7 drives the detection probe 8 to descend, so that the detection probe 8 contacts the battery core. Then, the contact switch of the relay is controlled by the withstand voltage detection device 5 to realize the on-off of the battery. By detecting parameters such as the voltage and current of the battery, the state and performance of the battery are judged. When the battery voltage and current exceed the set value, the relay will automatically disconnect the circuit to protect the battery from damage, so as to achieve the purpose of battery withstand voltage detection. After the detection is completed, the servo electric cylinder 7 drives the detection probe 8 to ascend. At the same time, the fixing mechanisms 306 on both sides of the profiling tooling 3 are disengaged from the fixation of the battery core. Then, the driving motor 305 is started, and the driving motor 305 drives the rightmost roller 304 to rotate. Through the rotation of the right roller 304 and the action of the belt drive, other rollers 304 are driven to rotate in the same direction and synchronously, and the battery after the detection is completed is transported to the right conveyor belt 4 and conveyed out of the equipment. At the same time, the next battery is transported to the profiling tooling 3, thereby realizing batch testing and improving the efficiency of battery detection.
