In the structure, the rotation of the turning plate 40 is driven by the driving structure, so that the labor of an operator can be saved, and the vibration testing efficiency of the battery is further improved.

As shown in fig. 3, 7, 9, 10, 13 and 14, in the present embodiment, the driving structure includes a driving lever 60 and a second pivot shaft 70 disposed at one end of the driving lever 60, and the first pivot shaft 80 is coaxial with the second pivot shaft 70. In other embodiments not shown in the drawings, the driving lever 60 and the flap 40 form an included angle therebetween, and the first pivot shaft 80 and the second pivot shaft 70 are separate structures and are fixedly connected. In the above structure, an included angle is formed between the driving lever and the turning plate 40, and the driving lever 60 and the turning plate 40 can rotate synchronously. When the battery needs to be turned over, the turning plate 40 is located below the first detection surface, an operator drives the free end of the driving lever 60 to rotate downwards towards the operating platform 1, and the turning plate 40 is lifted under the driving of the driving lever 60, so that the first detection surface of the battery is lifted, and the battery is turned over.

This way, the synchronism of the driving lever 60 and the flap 40 is better, and the stability of the driving lever 60 during driving is improved.

Because the included angle is formed between the driving lever 60 and the turning plate 40, the volume of the vibration testing device is larger when the vibration testing device is idle, and when the turnover device 30 is located at the initial position, the driving lever 60 is tilted upwards, so that the appearance is influenced. To solve the above problem, as shown in fig. 3 to 11, in the present embodiment, the first pivot shaft 80 is sleeved outside the second pivot shaft 70 and can rotate relative to the second pivot shaft 70, the turning plate 40 has an accommodating groove 42 for accommodating the driving lever 60, the driving lever 60 has an accommodating position accommodated in the accommodating groove 42 and a working position rotated out of the accommodating groove 42, the second pivot shaft 70 is provided with a pushing structure, the first pivot shaft 80 is provided with a matching structure, when the driving lever 60 is located at the accommodating position, a distance is provided between the pushing structure and the matching structure, the second pivot shaft 70 can rotate relative to the first pivot shaft 80, when the driving lever 60 rotates to the working position, the pushing structure and the matching structure are in abutting fit, and the second pivot shaft 70 can rotate together with the first pivot shaft 80.

When the battery 7 needs to be turned over, the driving lever 60 needs to be moved from the storage position to the working position, and then the battery 7 needs to be moved above the turning plate 40. When the free end of the driving lever 60 is continuously driven to rotate towards the operating platform 1, the second pivot shaft 70 rotates to drive the pushing structure to push the matching structure to rotate, so that the turning plate 40 on the first pivot shaft 80 is lifted upwards, and the driving lever 60 and the turning plate 40 rotate synchronously.

It should be noted that, in other embodiments not shown in the drawings, the driving structure may also be a driving motor, and an output shaft of the driving motor is connected to the second pivot shaft 70 to drive the second pivot shaft 70 to rotate, so as to drive the turnover device 30 to rotate from the initial position to the turnover position.

As shown in fig. 6, 8 and 11, in the present embodiment, the pushing structure includes a first protrusion 71, and the matching structure includes a second protrusion 81. The structure is simple and small, and the driving lever 60 and the turning plate 40 can be synchronously rotated by being conveniently arranged on the first pivot shaft 80 and the second pivot shaft 70.

The driving lever 60 can drive the turnover device 30 from the initial position to the turnover position, but when the turnover device 30 is reset, the driving lever 60 cannot drive the turnover device 30 to reset, and the turnover device needs to be manually reset by an operator, so that inconvenience is brought to the operation. In order to solve the above problem, as shown in fig. 6, 8 and 11, in the present embodiment, the first protrusion 71 includes a first blocking plate 711 and a second blocking plate 712 which are mutually angled, the first blocking plate 711 is connected with the second pivot shaft 70, an avoiding space 4 is formed between the first blocking plate 711, the second blocking plate 712 and the second pivot shaft 70, a bayonet 713 is disposed on the second blocking plate 712, and the second protrusion 81 is snapped into the bayonet 713 when the driving lever 60 rotates to the working position.

In the above structure, when the turnover device is located at the initial position, the driving lever 60 can be accommodated in the accommodating groove 42 of the turning plate 40, and the driving lever 60 and the turning plate 40 are parallel to the operation platform 1. When the battery 7 needs to be turned over, the driving lever 60 is rotated upwards by 90 degrees, the driving lever 60 is perpendicular to the operating platform 1, and the driving lever 60 moves from the accommodating position to the working position. The first projection 71 can now abut against the second projection 81, so that the flap 40 can rotate synchronously with the drive lever 60. After the driving lever 60 is moved to the working position, the battery is placed above the turning plate 40, and the driving lever 60 is driven to lift the turnover device 30 upwards, so that the first detection surface of the battery 7 is attached to the turnover surface 41. With the lifting of the turning plate, the first detection surface of the battery 7 is gradually far away from the operation platform 1, and the driving lever 60 is gradually engaged with the second detection surface of the battery 7 and gradually bears the weight of the battery 7.

At this time, the second detection surface of the battery 7 is attached to the operation platform 1, and the battery 7 is turned over. Then, the operator pushes the battery 7 from the turn-over platform area 3 to the vibration platform area 2 to perform a secondary vibration test on the battery. The structure can ensure that the overturning surface 41 is vertical to the operating platform 1 when the overturning device 30 is located at the overturning position, and prevent the battery 7 from being incapable of being overturned due to the fact that the overturning angle of the overturning surface 41 to the battery is too small.

The operator can push the battery 7 from the resting plane onto the roller 90, pushing it through the roller 90 to the vibrating device. When the battery 7 needs to be turned over, the cover 92 of the roller 90 needs to be opened first, so that the driving lever 60 can be rotated out of the roller 90, the battery is conveyed to the turning plate 40, then the driving lever 60 is continuously rotated to rotate the turning plate 40 to the turning position, and finally the purpose of turning over the battery is achieved. When it is desired to transport the next battery to be tested to the vibration table area 2, the cover 92 is placed over the barrel 91 to form a complete cylinder, and the battery is transported by the roller 90. It should be noted that the cover 92 is provided with a bayonet lock, the cylinder 91 is provided with a pin hole, the pin hole is a long hole, and the shape of the bayonet lock is matched with the pin hole.

In the above structure, the avoiding hole 6 can avoid the roller 90, so that the upper surface of the roller is higher than the upper surface of the supporting plate 13, and the roller 90 can convey the battery. Meanwhile, the avoidance hole 6 can ensure that the driving lever 60 and the turning plate 40 accommodated in the drum 90 can be smoothly rotated out. In addition, the avoidance groove 5 is a groove which is opened on the support plate 13 and is recessed downward.
