[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] A specific embodiment of this utility model provides a mechanism for battery OCV testing, unloading, and re-inspection, in conjunction with the attached... Figure 1-2 As shown, it mainly includes a feeding belt conveyor 1, a handling gantry 2, a first unloading conveyor 3, and a second unloading conveyor 4, wherein, A first unloading conveyor 3 is installed on the side of the feeding belt conveyor 1. A transport truss 2 is installed above the feeding belt conveyor 1 and the first unloading conveyor 3. A second unloading conveyor 4 is installed at the output end of the feeding belt conveyor 1 and is connected to the feeding belt conveyor 1. After the OCV test of the battery is completed, the feeding belt conveyor 1 transports a group of batteries to the unloading position. In this embodiment, a group of batteries is set to 16 batteries. The unloading position is located below the transport truss 2. The transport truss 2 is equipped with a mechanical gripper 21 and a re-inspection probe 211. The re-inspection probe 211 is used to re-inspect the batteries in this group, and the re-inspection result is sent to the system for the next step of operation. If the battery is good after re-inspection, the mechanical gripper 21 picks up the battery and transports it to the first unloading conveyor 3. If the battery is defective after re-inspection, the mechanical gripper 21 does not transport it. After all batteries have been re-inspected, the feeding belt conveyor 1 pushes the defective batteries to the second unloading conveyor 4 to complete the unloading of the defective batteries.

[0018] Furthermore, the handling truss 2 is provided with columns 22 and crossbeams 23. In this embodiment, two columns 22 are provided, symmetrically arranged at both ends of the feeding belt conveyor 1, and fixed to the ground to provide support. The two ends of the crossbeams 23 are respectively fixed to the tops of the two columns 22, so that the crossbeams 23 are parallel to the ground. A horizontal moving track 24 is provided on the crossbeams 23. In this embodiment, the mechanical gripper 21 is provided with a moving base. A long straight rack is fixedly installed on one side of the moving track 24 where the crossbeams are located. One or more drive gears are installed on the moving base of the mechanical gripper 21 and driven by a motor. The motor rotates to drive the gears, and the gears mesh with the fixed rack. When the gears rotate, since the rack is fixed, the gears will "roll" along the rack, thereby driving the entire moving base of the mechanical gripper 21 to move along the track direction.

[0019] Furthermore, the mechanical gripper 21 is also equipped with a lifting cylinder 212 and a gripper body 213. The lifting cylinder 212 is fixedly installed with the movable base, and the gripper body 213 is installed at the output end of the lifting cylinder 212. The output direction of the lifting cylinder 212 is vertical, which is used to drive the gripper body 213 to move in the vertical direction so that the gripper body 213 can grasp the battery.

[0020] Furthermore, in this embodiment, two sets of mechanical grippers 21 are provided, and the linkage of the two sets of mechanical grippers 21 can improve the re-inspection efficiency.

[0021] Furthermore, a re-inspection probe 211 is provided on the side of the gripper body 213, and the re-inspection probe 211 does not affect the opening and closing of the gripper body 213. The re-inspection probe 211 is provided with two vertically downwards, and the distance between the two re-inspection probes 211 is consistent with the distance between the positive and negative terminals of the battery. The mechanical gripper 21 moves laterally along the moving track 24 to above the battery to be re-inspected. The lifting cylinder 212 descends so that the re-inspection probe 211 contacts the positive and negative terminals of the battery to be re-inspected for re-inspection, and the test results are uploaded to the system.

[0022] Furthermore, the feeding conveyor belt 1 is equipped with battery placement compartments 11 and blocking devices 12. There are 16 battery placement compartments, and in this embodiment, the number of batteries to be re-inspected is 16 per group. The compartments are arranged parallel and symmetrically. The blocking device 12 is located at the outer front end of the battery placement compartments 11, used to separate the batteries to be re-inspected between the front and rear groups. The blocking device 12 is equipped with a top plate 121, a blocking rod 122, a bottom plate 123, and a cylinder 124. The lengths of the top plate 121 and the bottom plate 123 are consistent with the lateral length of the 16 battery placement compartments 11. The bottom plate 123 is slightly lower than the bottom of the battery placement compartments 11 and is fixed in the feeding conveyor belt 1. The top plate 121 is arranged parallel and symmetrically above the bottom plate 123. The cylinder 124 is located on the bottom plate 123. Below cylinder 124, the output end of cylinder 124 passes through the bottom plate 123 and is fixedly connected to the bottom of top plate 121. Several blocking rods 122 are symmetrically arranged on both sides of cylinder 124 and are fixedly connected to the bottom of bottom plate 123 and top plate 121. When cylinder 124 retracts to its lowest position, blocking rods 122 and top plate 121 move downwards, and the bottom surface of top plate 121 contacts the top surface of bottom plate 123. At this time, the top surface of top plate 121 and the bottom surface of battery storage compartment 1 are on the same plane, so that the subsequent group of batteries to be re-inspected can be transported into battery storage compartment 11 without obstruction. When cylinder 124 rises to its highest position, blocking rods 122 and top plate 121 move upwards, and top plate 121 and several blocking rods 122 can block the subsequent group of batteries to be re-inspected from being transported into battery storage compartment 11.

[0023] Furthermore, the second feeding conveyor 4 is set at an angle to the ground, and the higher end of the second feeding conveyor 4 is connected to the output end of the feeding belt conveyor 1. The defective batteries output from the feeding belt conveyor 1 are transported to the input end of the second feeding conveyor 4. Since the second feeding conveyor 4 is set at an angle, the defective batteries can be transported quickly by gravity.

[0024] The working principle of this embodiment: The cylinder 124 of the blocking device 12 of the feeding belt conveyor 1 descends, causing the top plate 121 and the blocking rod 122 of the blocking device 12 to descend, and the first group of batteries to be re-inspected enters the battery placement chamber 11. Then the cylinder 124 rises, driving the top plate 121 and the blocking rod 122 of the blocking device 12 to rise, blocking the second group of batteries to be re-inspected from entering the battery placement chamber 11. The mechanical gripper 21 of the handling truss 2 moves to above the battery to be re-inspected via the moving track 24. The re-inspection probe 211 is lowered to the gripper body 213 via the lifting cylinder 212. The re-inspection probe 211 contacts the positive and negative terminals of the battery to be re-inspected for re-inspection and uploads the test results to the control system. After analyzing the test results, the control system determines whether the battery is good. If it is good, the gripper body 213 picks up the good battery and transports it to the first unloading conveyor 3. If it is defective, the mechanical gripper 21 does not perform any further operations, but only performs the work of re-inspecting the battery and transporting the good battery. After all the batteries to be re-inspected have been inspected, only defective batteries remain in the battery placement bin 11 of the feeding belt conveyor 1. The feeding belt conveyor 1 outputs the defective batteries to the second unloading conveyor 4, where they are uniformly received by gravity.

[0025] Complete the overall re-inspection, classification, and transportation of the first group of batteries, and then proceed with the re-inspection of the next group of batteries.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
