Driven by the servo motor, the threaded rod can accurately control the left and right movement position of the unloading bin to adjust the unloading position. The limit rod ensures the stability of the unloading bin during movement, prevents it from offsetting or shaking, and improves the working accuracy and reliability of the equipment. The unloading bin is set to a funnel shape and can store lithium batteries to be sorted. It is movable The dynamic design can adjust the unloading position as needed, so that the lithium batteries can accurately enter the classification mechanism for sorting, which improves the flexibility and work efficiency of the equipment.

Its high-precision rotation can achieve fine-tuning of the unloading bin position to meet different unloading requirements and improve the automation level and work efficiency of the equipment. The limit plate can support and limit the fixed groove, rubber roller, connecting rod and reduction motor. The fixed groove provides a specific channel and position for the sorting of lithium batteries, so that the lithium batteries can be transported on a fixed path.

[0033] Specifically, such as Figure 3 、 Figure 4 As shown, the baffle 603 is fixedly connected to the top of the hydraulic rod 604 , the baffle 603 is slidably connected to the bottom of the inner side of the fixing groove 502 , and the microcontroller 605 is fixedly connected to the right side of the inner side of the working box 1 .

By setting up a support plate 602, a stable installation base is provided for the hydraulic rod 604, ensuring that the hydraulic rod 604 does not shake during operation, ensuring the precise position control of the baffle 603, and by setting the baffle 603 to be arc-shaped, it can support and limit the lithium battery, and under the action of the hydraulic rod 604, it can slide up and down according to the recognition result, and the baffle When 603 slides downward, the lithium batteries will slide into the inner side of the receiving box 3 through the two sides of the baffle 603, realizing automatic classification, improving the automation level and sorting efficiency of the equipment, and by setting the hydraulic rod 604, the lifting and lowering of the baffle 603 can be controlled quickly and accurately, and the classification operation of the lithium batteries can be responded quickly, thereby improving the speed and accuracy of sorting.

[0036] Specifically, such as Figure 4 As shown, a protective shell 14 is fixedly connected to the surface of the microcontroller 605, and the surface of the protective shell 14 is coated with an antistatic coating.

[0037] In this embodiment: by setting the angle of the camera 601 to 45° downward, the camera 601 is set to a 45° angle to shoot the lithium battery from a specific tilt angle, which can obtain more comprehensive and three-dimensional image information, and better identify the appearance characteristics, size and possible defects of the lithium battery.

[0041] Working principle: First, the user places the working box 1 in a suitable working position. When preparing to sort the lithium batteries, the lithium batteries to be sorted are placed in the lower bin 10. Then, the power is turned on and the servo motor 12 is started. The servo motor 12 starts to run, and its output end drives the threaded rod 8 to rotate. Since the front slider 11 is threadedly connected to the threaded rod 8, the rear slider 11 slides on the surface of the limit rod 9, and the slider 11 is bolted to the lower bin 10, so that the lower bin 10 can slide smoothly and horizontally in the limit slots 7 on both sides of the top of the working box 1. As the lower bin 10 continues to move, the lithium batteries are taken out one by one. The bottom of the unloading bin 10 leaks into the inner side of the fixed groove 502. After the lithium battery enters the fixed groove 502, the user powers on and starts the microcontroller 605 and the reduction motor 506. The output end of the reduction motor 506 drives the left rubber roller 503 to rotate. With the help of the transmission effect of the rotating belt 505, each rubber roller 503 realizes synchronous rotation. The rubber roller 503 drives the lithium battery to rotate slowly on the top of the baffle 603 through rotational friction. Afterwards, the camera 601 on the top of the working box 1 performs multi-angle image acquisition on the rotating lithium battery. Once the camera 601 detects damage, deformation or leakage on the surface of the lithium battery, When the battery is out of the fixed groove 502 and there is no cover on both sides of the baffle 603, the lithium battery will roll to both sides of the baffle 603 due to the arc-shaped design of the baffle 603, and then fall into the inside of the receiving box 3. Then, the user controls the left electric push rod 4 to push the receiving box 3 to slide toward the right box outlet 2 so as to facilitate the inspection inside the receiving box 3. Lithium batteries that are found to be damaged, deformed, and leaking are collected and processed centrally. After processing, the electric push rod 4 drives the receiving box 3 to reset. After that, the microcontroller 605 continues to work and controls the hydraulic rod 604 to continue to descend, so that the intact lithium batteries fall into the inside of the receiving box 3. Then, the user controls the rear electric push rod 4 to push the receiving box 3 toward the front outlet 2 to collect the intact lithium batteries. After the collection is completed, the rear electric push rod 4 drives the receiving box 3 to reset, and the intact lithium batteries are sent to the subsequent process for further processing. Finally, the user repeats this operation to pre-sort the lithium batteries.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
