[0033] Working principle:
[0034] A component plate 2 and a long shaft 14 are installed in a component placement groove 104 located in the middle of the water platform 101. The component plate 2 is rotatably connected to the component placement groove 104 via the long shaft 14, allowing the other side of the component plate 2 to be lifted. An internal space 103 is provided inside the water platform 101, and an electric telescopic rod 12 and a gear condition 4 are respectively provided at the bottom of the internal space 103. The electric telescopic rod 12 can push the gear condition 4 to move back and forth in the slide section 105 at the bottom of the internal space 103. The gear condition 4 meshes with the gear component 5, causing the gear component 5 to rotate back and forth. A support rod 6 is inserted into the gear component 5, and both ends of the support rod 6 are inserted into the two side walls of the internal space 103 for support. The lower ends of the first guide rods 7 are sleeved on both sides of the support rod 6, making the first guide rods 7, the support rods 6, and the gear component 5 an integral unit. When the gear component 5 rotates, the other end of the first guide rod 7 can be lifted. Raising or lowering, the other end of the first guide rod 7 is rotatably connected to one end of the second guide rod 8 by a rotating rod 9, and the other end of the second guide rod 8 is inserted into the support frame 10 and rotatably connected by a pin 11. At the same time, the support frame 10 is fixedly connected to the bottom of the placement plate 2. When the charging module is placed on the placement plate 2, the electric telescopic rod 12 is activated to push the gear condition 4 to move, so that the gear 5 and the support rod 6 rotate, raising the connection between the first guide rod 7 and the second guide rod 8, and the first guide rod 7 and the second guide rod 8 tend to be perpendicular to the horizontal platform 101. Then the second guide rod 8 will lift the side of the placement plate 2 with the support frame 10, and the placement plate 2 will form an angle with the long axis 14 as the center. In this way, the charging module is raised at a certain angle and faces the inspection personnel. At the same time, the charging module is supported by the stop block 3 to prevent it from slipping. Finally, the inspection instrument assembly 16 above the vertical frame 102 is used to inspect the charging module.
