[0022] Specifically, referring to Figure 1 , the clamping mechanism 4 includes a first clamping part and a second clamping part, wherein the first clamping part includes a first stop plate 61 and a first movable plate 62 arranged oppositely on the upper side of the test bench 1, and the second clamping part includes a second stop plate 71 and a second movable plate 72 arranged oppositely on the upper side of the test bench 1, specifically, in this embodiment, the first clamping part and the second clamping part clamp the batteries in the horizontal and vertical directions respectively, generally, the shell of the battery pack is usually a cubic structure, and the first clamping part and the second clamping part clamp the battery pack in two opposite surfaces, of course, for the battery pack with other shapes, the directions of the first clamping part and the second clamping part can be changed to adapt to the shells with different shapes. In addition, it should be noted that the second movable plate 72 is arranged opposite to the discharging conveyor 3, and the second movable plate 72 also has the function of transferring the batteries on the test bench 1 to the discharging conveyor 3, after the vibration test is completed, the batteries are pushed and transferred to the discharging conveyor 3 by the second movable plate 72 to realize discharging.

[0023] Referring to Figure 1 and Figure 2 , the first pushing mechanism 5 specifically includes a roller shaft conveyor 51 arranged at the discharging end of the feeding conveyor 2, the roller shaft conveyor 51 is a non-powered conveyor, one end of the roller shaft conveyor 51 is close to the test bench 1, the upper end surface of the roller shaft conveyor 51 is preferably flush with or slightly higher than the upper end surface of the test bench 1, a first electric push rod 52 is arranged at the end opposite to the test bench 1, a first push plate 53 is arranged on the telescopic rod of the first electric push rod 52, in addition, a limiting stop plate 54 is arranged on the roller shaft conveyor 51 opposite to the discharging end of the feeding conveyor 2, the batteries to be tested are conveyed to the roller shaft conveyor 51 by the feeding conveyor 2 and are blocked by the limiting stop plate 54, then the first electric push rod 52 drives the first push plate 53 to push the batteries on the roller shaft conveyor 51 and transfer them to the upper end surface of the test bench 1, so that the automatic loading of the batteries is completed.

[0024] The battery transferred to the upper end face of the test table 1 is automatically clamped by the clamping mechanism 4, referring to Figure 1 and Figure 3 More specifically, the first baffle 61 includes an inclined baffle 611, guide columns I 612 and springs I 613, wherein the guide columns I 612 are provided at the bottom of the inclined baffle 611, the upper end face of the test table 1 is provided with a first combined groove 17 matched with the inclined baffle 611 and the guide columns I 612, the inclined baffle 611 can be completely embedded in the first combined groove 17, the guide columns I 612 play a limiting and guiding role, and one spring I 613 is respectively sleeved on each guide column I 612, the upper end of the spring I 613 abuts against the lower side of the inclined baffle 611, and the lower end of the spring I 613 abuts against the bottom wall of the first combined groove 17. Due to the action of the spring I 613, the inclined baffle 611 is in an extended state. In addition, it should be noted that the inclined surface of the inclined baffle 611 is close to the first pushing mechanism 5. When the first pushing mechanism 5 transfers the battery from the feeding conveyor 2 to the test table 1, the bottom surface of the battery contacts the inclined surface of the inclined baffle 611, and the battery gradually presses the inclined baffle 611 into the first combined groove 17 by its own weight, so that the inclined baffle 611 is gradually pressed into the first combined groove 17. When the battery completely passes over the inclined baffle 611, the inclined baffle 611 is driven by the spring to extend out of the first combined groove 17.

[0025] Referring to Figure 3 and 4 The first movable plate 62 includes a plate body 621 and a cylinder 622 driving the movement of the plate body 621, and a pressure sensor 623 is arranged between the plate body 621 and the movable rod of the cylinder 622. The pressure sensor 623 is used to monitor the pressing force in the battery clamping process to prevent excessive extrusion from deforming the battery shell.

[0026] Referring to Figure 1 , Figure 3 and Figure 5, the plate body 621 is driven by the air cylinder 622 to move towards the first baffle 61, and the plate body 621 is matched with the inclined baffle 611 to realize clamping of the battery. Since the battery is in contact with the non-inclined surface of the inclined baffle 611, the battery will not pass over the inclined baffle 611 when being pressed by the plate body 621. While realizing clamping in this direction, the second clamping part also synchronously clamps. Specifically, the second baffle 71 includes a rectangular block 711 connected with one end of a guide column II 712, a spring II 713 is sleeved on the guide column II 712, the other end of the guide column II 712 is provided with an abutting wheel 714, the bottom of the abutting wheel 714 is provided with an inclined block 715, the bottom of the inclined block 715 is provided with a sliding block 716. In this embodiment, the combination of the rectangular block 711, the guide column II 712, the spring II 713, the abutting wheel 714, the inclined block 715 and the sliding block 716 is provided with two groups. The two sliding blocks 716 are arranged on a straight slide rail 717, and the two sliding blocks 716 are connected in series in a fixed manner. The straight slide rail 717 is connected with the test bench 1 through a support plate 718. One of the sliding blocks 716 is connected with the movable rod of the air cylinder 622 through a connecting rod 719. The test bench 1 is provided with a second combined groove 18 matched with the rectangular block 711 and the guide column II 712. When the air cylinder 622 drives the plate body 621 to clamp the battery, the movable rod of the air cylinder 622 is extended to drive the connecting rod 719 to synchronously operate. When the connecting rod 719 drives the sliding block 716 to slide along the straight slide rail 717, the inclined block 715 connected with the sliding block 716 also synchronously operates. The inclined surface of the inclined block 715 is in abutment with the abutting wheel 714. With the movement of the inclined block 715, the position of the abutting wheel 714 relative to the inclined surface changes from low to high. In this way, the rectangular block 711 is driven by the guide column II 712 to extend from the second combined groove 18, so as to limit the battery on the side opposite to the second movable plate 72. When the movable rod of the air cylinder 622 is retracted, the rectangular block 711 is retracted into the second combined groove 18 through the action of the spring II 713.

[0027] The structure of the second movable plate 72 is similar to that of the first movable plate 62, and includes a second electric push rod 721 and a second push plate 722 arranged on the telescopic rod of the second electric push rod 721. After the test is completed, the rectangular block 711 is retracted into the second combined groove 18. At this time, the second electric push rod 721 drives the second push plate 722 to continue to extend, so as to push the battery and transfer it to the material returning conveyor 3. The structure of the material returning conveyor 3 is the same as that of the material feeding conveyor 2.
