[0006] Aluminium alloy battery tray insulation pressure -resistant coating synchronous detection equipment, one end of rack is provided with cantilever hanger, several vertical lifting cylinders are installed in cantilever hanger, the piston head of lifting cylinder is connected with lifting frame, and several detection heads are fixedly connected below lifting frame.

[0007] When the battery tray is located directly below the cantilever hanger, the cylinder drives the detection head to descend and contact the inner cavity of the battery tray. The detection head is connected to the withstand voltage tester through wires, and the tester display screen displays the insulation performance and withstand voltage performance of the surface to be tested, thereby realizing insulation detection of the power battery tray. If the insulation layer is broken, it will be displayed on the tester display screen, and the insulation withstand layer in the inner cavity of the tray can be found by the naked eye.

[0008] Since the battery tray can be divided into several recess cavities by the cross beam, the number of detection heads matches the number of recesses, and each detection head is connected to the tester through wires. Each pressing plate in the detection head is electrically connected through wires, and the insulation and withstand voltage parameters of any detection head can be seen on the tester.

The detection positive plate contacts the bottom surface of the battery tray, and the detection side plates simultaneously contact the inner side surface of the battery tray. Since the detection positive plate and the detection side plates are connected to each other through wires, the detection head forms a shape that can simultaneously contact the entire inner side surface of the battery tray, eliminating the need for separate detection of multiple inner side surfaces of the battery tray, thereby greatly improving detection efficiency.

[0010] A gas control valve is installed in the middle of the detection positive plate, and the gas control valve is connected to the side pushing cylinders through air pipes. The four side pushing cylinders are in parallel relationship with the gas control valve, so that the actions of the side pushing cylinders are unified and consistent.

[0011] A slide rail is arranged on the length direction of the upper end surface of the rack, and the slide rail is slidably connected to a sliding support plate through a sliding block. The sliding support plate supports the battery tray above.

[0012] One side of the rack is a feeding and discharging station, and the other side is a detection station. The battery trays before and after detection are translated through the track and then carried for feeding and discharging, thereby improving the efficiency of work. The sliding support plate can be driven by manual or cylinder.

[0013] The use method includes the following steps:

[0014] A. The sliding support plate is located at the feeding and discharging station, and the battery tray is placed on the sliding support plate.

[0015] B. The sliding support plate is slid to the detection station.

[0016] C. The lifting cylinder drives the lifting frame to descend with each detection head until the detection positive plate contacts and presses the bottom surface of the inner cavity of the battery tray.

[0017] D. The side pushing cylinder is ejected until each detection side plate contacts and presses each side surface of the inner cavity of the battery tray.

[0018] E, read the test results of the inner cavity of each battery tray groove on the insulation withstand voltage tester, if the data is abnormal, check the specific plane of the insulation withstand voltage coating breakdown point with naked eye and confirm, and record;

[0019] F, the side pushing cylinder and the lifting cylinder are retracted, and the battery tray is discharged to the upper and lower discharge stations.

[0020] Advantages of the utility model
