[0001] The present invention relates to the technical field of lithium batteries, in particular to a testing structure of lithium batteries. Background Art

[0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and a non-aqueous electrolyte solution. Lithium batteries are widely used in energy storage power systems such as hydropower, thermal, wind and solar power stations, uninterruptible power supplies for postal and telecommunications, as well as power tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, aerospace and other fields. After production, lithium batteries need to be tested for on / off to determine the quality of the lithium batteries.

[0003] Most existing testing devices connect the positive and negative poles of the lithium battery to determine whether the lithium battery is qualified. However, when removing the lithium battery after the test, the operator is required to remove the lithium battery from the testing device, which is complicated and reduces the labor intensity of the operator. Summary of the invention

[0009] Preferably, the bottom ends of the incomplete gear 1 and the incomplete gear 2 are both meshed with the rack, the incomplete gear 1 is located above the hanging plate 1, and the incomplete gear 2 is located above the hanging plate 2.

[0010] Preferably, there are two movable grooves, which are respectively located at the front and rear sides of the placement groove and the material withdrawal groove, and the connecting rod is movably connected in the movable grooves.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The present invention opens a material return groove on the top surface of the bottom plate. After the lithium battery detection is completed, the second hanging plate drives the second detection needle to move forward through the connecting rod, so that the second detection needle pushes the lithium battery located in the placement groove to move forward.

The connecting rod 9 is movably connected in the movable groove 4. When the lithium battery is pushed to the top of the withdrawal groove 3, the lithium battery falls downward from the withdrawal groove 3 under the action of gravity. At this time, the lithium battery can be directly caught under the withdrawal groove 3, and the operator does not need to take out the lithium batteries one by one. The operation is simple and the labor intensity of the operator is improved. The inner cavity of the movable groove 4 is movably connected with a connecting plate 1 5 and a connecting plate 2 6. The top surfaces of the connecting plates 1 5 and 2 6 are fixedly installed with baffles 19. The detection needle 1 7 and the detection needle 2 8 are both located below the baffle 19. By installing the baffle 19 on the top surfaces of the connecting plates 1 5 and 2 6, the baffle 19 is on the detection needle 1 and 2 are shielded to prevent the lithium battery from being stuck between the detection needle 1 7 and the detection needle 2 8 when the lithium battery is placed. The detection needle 1 7 and the detection needle 2 8 are fixedly installed on the side of the connecting plate 1 5 and the connecting plate 2 6 close to the center of the bottom plate 1 respectively. The detection needle 1 7 pushes the lithium battery to the left. When the incomplete gear 14 and the rack 12 are rotated away, the detection needle 1 7 and the detection needle 2 8 are respectively in contact with the two ends of the lithium battery to perform on-off detection on the lithium battery. The connecting plate 1 5 and the connecting plate 2 6 are fixedly installed on the side away from the center of the bottom plate 1. The other end of the connecting rod 9 is fixedly installed with a hanging plate 10 and a hanging plate 2 11.

The top surfaces of the bottom ends of the hanging plates 10 and 11 are fixedly installed with racks 12. The bottom surface of the bottom plate 1 is fixedly installed with a motor 13. The motor 13 drives the incomplete gear 1 14 and the incomplete gear 2 15 to rotate. The bottom end of the incomplete gear 2 15 is not meshed with the rack 12, so that the incomplete gear 1 14 drives the hanging plate 1 10 to move to the left, so that the hanging plate 10 drives the detection needle 1 7 to move to the left through the connecting rod 9 and the connecting rod 9. The output end of the motor 13 is fixedly sleeved with the incomplete gear 1 14 and the incomplete gear 2 15.The bottom ends of the incomplete gear 14 and the incomplete gear 2 15 are meshed with the rack 12. The incomplete gear 14 is located above the hanging plate 10, and the incomplete gear 2 15 is located above the hanging plate 2 11. The motor 13 drives the incomplete gear 14 and the incomplete gear 2 15 to reverse. At this time, the incomplete gear 14 drives the hanging plate 10 to move forward, so that the hanging plate 10 drives the detection needle 1 7 to leave the top of the material return slot 3. At this time, the incomplete gear 14 rotates away from the rack 12, and the incomplete gear 2 15 contacts the rack 12, so that the incomplete gear 2 15 drives the hanging plate 2 11 to move forward.

[0021] Working principle: When in use, in the initial state, the detection needle 1 7 is located above the material return groove 3, and the detection needle 2 8 is located on the left side of the placement groove 2. At this time, the lithium battery to be tested is placed in the placement groove 2. The corrugated groove on the bottom of the placement groove 2 can separate the lithium batteries from each other, which is convenient for placing the lithium battery. After the lithium battery is placed, the motor 13 drives the incomplete gear 1 14 and the incomplete gear 2 15 to rotate. At this time, the bottom end of the incomplete gear 1 14 is engaged with the rack 12, and the bottom end of the incomplete gear 2 15 is not engaged with the rack 12, so that the incomplete gear 1 14 drives the hanging plate 10 to move to the left, so that the hanging plate 10 drives the detection needle 1 7 to move to the left through the connecting rod 9 and the connecting rod 9, so that the detection needle 1 7 pushes the lithium battery to the left. When the incomplete gear 14 is rotated away from the rack 12, the detection needle 1 7 and the detection needle 2 8 are respectively in contact with the two ends of the lithium battery to perform on-off detection on the lithium battery. The qualified lithium battery is indicated The lamp 18 conducts electricity, making the indicator light 18 light up. Unqualified lithium batteries cannot light up the indicator light 18. When the detection is completed, the motor 13 drives the incomplete gear 14 and the incomplete gear 2 15 to reverse. At this time, the incomplete gear 14 drives the hanging plate 10 to move forward, so that the hanging plate 10 drives the detection needle 17 to leave the top of the return groove 3. At this time, the incomplete gear 14 rotates away from the rack 12, and the incomplete gear 2 15 contacts the rack 12, so that the incomplete gear 2 15 drives the hanging plate 2 11 to move forward. The hanging plate 2 11 drives the detection needle 2 8 to move forward through the connecting rod 9, so that the detection needle 2 8 pushes the lithium battery located in the placement groove 2 to move forward. When the lithium battery is pushed to the top of the return groove 3, the lithium battery falls downward from the return groove 3 under the action of gravity. At this time, the lithium battery can be directly caught below the return groove 3, and the operator does not need to take out the lithium batteries one by one. The operation is simple, which improves the labor intensity of the operator.
