by arranging the buffer unit, when the first cylinder 5 moves upwards or downwards, the extrusion force and the pulling force of the vertical rod 17 to the push plate 18 can not bend or break the connecting rod between the push plate 18 and the top plate 20; the vertical rod 17 is slidably connected in the cylinder 23 through a spring 22, and even if the downward travel amount of the first cylinder 5 is larger than the connected travel amount, the spring 22 is compressed and buffers part of the travel amount to protect the push plate 18, the connecting rod and the top plate 20 parts;
the roller body 25 is arranged on the bracket 2, so that a dropped battery can be extruded in the bracket 2 by the roller body 25, smoothness of the battery in the bracket 2 and easiness of discharging the battery by the post-stage top plate 20 can be ensured, and a rubber layer is arranged on the surface of the roller body 25, so that the battery is in soft and hard contact with the roller body 25, and stability of the battery can be improved;
after the battery is placed in the bracket 2, if the battery cannot be prevented in a centralized manner, one end part of the battery cannot be placed in the cylinder 6, namely, cannot penetrate through the rubber ring 7 and is fully submerged and covered by clean water, even if the end part of the battery has a leakage problem, the injected gas cannot be ejected from clean water, the side leakage effect is poor, meanwhile, the roller body 25 is arranged, and the rubber layer on the surface of the roller body 25 makes the battery difficult to move along the axis, so that the ball 26 is arranged on the surface of the roller body 25, the ball 26 can enable the axis of the battery to move easily, after the battery is placed, the battery moves left and right, so that the battery is placed in the middle position of the bracket 2 as much as possible, then the cylinder 6 is close, and the end part of the battery penetrates through the rubber ring 7 and is placed in the cylinder 6, so that both ends of the battery are placed in the cylinder 6;
the upper surface of the top plate 20 is convexly arranged, so that when the top plate 20 is used for pushing up the battery for discharging, the battery can be pushed up to one side, so that the battery can be smoothly separated from the bracket 2, and the battery pushed up is not dropped onto the bracket 2 again, thereby influencing the test of the follow-up spot inspection battery; the discharge opening 27 is provided so that the battery falling obliquely can be quickly and timely separated from the side leakage tool, but not fall on the push plate 18, and the execution of the side leakage tool is affected.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
