Description

[Technical field]

[0001] The present invention relates to the technical field of used batteries, and in particular to a rapid testing device for used batteries. [Background technology]

[0002] New energy, also known as non-conventional energy, refers to various forms of energy other than traditional energy, such as solar energy, geothermal energy, wind energy, marine energy, biomass energy, and nuclear fusion energy, which are energy sources that have just begun to be developed and used, or are being actively researched but have not yet been widely adopted. With the continuous development and research of new energy, several processes have been produced with new energy as the core, of which the one that has the greatest impact is the new energy vehicle. A new energy vehicle is a vehicle that uses non-conventional vehicle fuel as a power source (or uses conventional vehicle fuel and a new vehicle output device) and is equipped with advanced technical principles, new technologies, and new structures, formed by integrating advanced technologies for vehicle output control and driving. As the new energy vehicle industry matures, the batteries used also need to be replaced. The replaced batteries are called used batteries. Used batteries can be cascaded after replacement, but the process of cascading used batteries requires flaw detection testing.

[0003] Currently available flaw detection devices for used batteries cannot automatically inspect batteries during use. An operator must carry the used batteries to the position of the flaw detection device, and after the inspection is completed, remove the used batteries from the flaw detection device and transport them to a designated location. This not only increases the intensity and difficulty of the operator's work, but also reduces the inspection efficiency of used batteries, affects the follow-up work of used batteries, and makes it inconvenient for operators to perform flaw detection for long periods of time. Moreover, during the transportation of used batteries, accidents are likely to occur in which the used batteries fall to the ground and are directly damaged, which is not helpful for operators to inspect used batteries.

[0004] Therefore, to solve the above technical problems, it is necessary to design a high-speed inspection device for used batteries. Summary of the Invention [Problem to be solved by the invention]

When the used battery body 13 moves to the center of the flaw detection groove 30, the flaw detector 2 quickly inspects the used battery body 13. The third servo motor 20 rotates the used battery body 13 through the rotating shaft 19, and the flaw detector 2 can inspect the used battery body 13 from multiple angles, saving inspection time and improving the inspection efficiency of the used battery body 13. After the inspection of the used battery body 13 is completed,The first servo motor 3 continues to work, and the connection box 5 drives the second installation tube 10 to move to the right, at this time, the baffle plate 36 and the connection groove 12 are in an overlapping state, the fourth servo motor 35 drives the connection block 40 to rotate through the connection box 5, and the block 40 rotates the baffle plate 36 to the upper end of the connection groove 12, which is convenient for the used battery body 13 to exit from the flaw detector 2, at this time, the baffle plate 36 leaves the connection groove 12, and the limit strip 33 is convenient for limiting the position of the baffle plate 36, which is more convenient for the inspector to work, after the used battery body 13 is completely exited from the flaw detector 2, the inspector takes out the inspected used battery body 13 from the clamp groove 38, the first servo motor 3 rotates in the reverse direction, and the connection box 5 drives the second installation tube 10 to move to the left, and the limit strip When the second mounting cylinder 10 moves to the position of the connecting box 6, the first servo motor 3 stops working, and the inspector installs the next used battery body 13 to be inspected, and repeats the inspection work again, thereby realizing automatic inspection of the used battery body 13 during the inspection by the inspector. The inspector does not need to carry the used battery body 13 back and forth, so that the difficulty and strength of the inspection work of the inspector is reduced, and manpower is saved. The rotating inspection of the used battery body 13 improves the inspection efficiency of the used battery body 13, and realizes the rapid inspection of the used battery body 13. Here, a support block 32 is fixedly connected to the lower end of one side of the second mounting cylinder 10 close to the first mounting cylinder 9, and the support block 32 and the first mounting cylinder 9 are fixedly connected, which further improves the structural closeness between the second mounting cylinder 10 and the connecting box 5, and is convenient for improving the stability of the second mounting cylinder 10 during movement.
