[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0021] Reference Figures 1-5As shown, a battery sorting device includes a base plate 1 with a discharge port 3 extending through the center of its upper surface. A PLC controller 2 is fixedly connected to the left side of the discharge port 3 on the upper surface of the base plate 1. The PLC controller 2 provides the core component for the automated control of the device. It can receive and process detection data and control the actions of other components according to a preset program, realizing automatic battery detection and sorting. The built-in detection program can perform real-time analysis of parameters such as battery voltage, capacity, and internal resistance, quickly and accurately determining whether a battery is a good product, thus improving detection efficiency and accuracy. Simultaneously, it can send instructions to other components based on the detection results, achieving automated operation of the device and reducing manual labor. Intervention reduces labor intensity. Two positioning blocks 4 are fixedly connected to the right side of the discharge port 3 on the upper surface of the base plate 1. A material ejection mechanism 11 is connected to the right side of the positioning blocks 4 on the upper surface of the base plate 1. A detection mechanism 12 is set above the positioning blocks 4 on the upper surface of the base plate 1. An installation frame 7 is fixedly connected to the bottom of the base plate 1 at the discharge port 3. A rotating shaft 8 is rotatably connected inside the installation frame 7. A guide plate 9 is fixedly connected above the rotating shaft 8. The guide plate 9 can rotate to different positions according to the battery detection results, guiding the battery to the good product discharge slot 5 or the defective product discharge slot 6, which plays a role in guiding battery classification and improving the accuracy and efficiency of classification. A servo motor 10 that drives the rotating shaft 8 to rotate is fixedly installed on the rear side of the installation frame 7.

[0022] Furthermore, a good product discharge trough 5 is fixedly connected to the left side of the mounting frame 7 on the base plate 1, and a defective product discharge trough 6 is fixedly connected to the right side of the mounting frame 7 on the base plate 1. The good product discharge trough 5 enables the classification and collection of good products, which is convenient for subsequent processing and packaging. The defective product discharge trough 6 enables the classification and collection of defective products, which is convenient for subsequent rework or scrapping.

[0023] Furthermore, the unloading mechanism 11 includes a connecting frame 1101, which is fixedly connected to the upper right side of the base plate 1. A fixing block 1102 is fixedly connected above the connecting frame 1101. Guide rods 1103 are slidably connected to both the front and rear sides of the fixing block 1102. A first connecting block 1104 is fixedly connected to the left side of the two guide rods 1103. An unloading plate 1105 is fixedly connected to the left side of the first connecting block 1104. The unloading plate 1105 moves to the left under the drive of the guide rods 1103, pushing the battery into the discharge port 3. The structure is simple and the operation is convenient.

[0024] Furthermore, a second connecting block 1106 is fixedly connected to the right side of the two guide rods 1103, and a connecting plate 1108 is fixedly connected to the bottom of the second connecting block 1106. A servo electric cylinder 1109 is fixedly connected inside the connecting frame 1101. The output end of the servo electric cylinder 1109 is connected to the left side of the connecting plate 1108 through a connector. The servo electric cylinder 1109 can accurately control the movement of the guide rods 1103 according to the instructions of the PLC controller 2 to realize the automatic unloading of the battery.

[0025] Furthermore, a return spring 1107 is sleeved on the outer side of each of the two guide rods 1103. One end of the return spring 1107 is fixedly connected to the right side of the fixing block 1102, and the other end of the return spring 1107 is fixedly connected to the left side of the second connecting block 1106. After the material is unloaded, the return spring 1107 can automatically reset the guide rods 1103 and the unloading plate 1105 to their initial positions, preparing for the next unloading and improving the operating efficiency of the device.

[0026] The detection mechanism 12 includes four fixed rods 1201. The bottom of the four fixed rods 1201 is fixedly connected to the upper surface of the base plate 1. A fixed plate 1202 is fixedly connected above the four fixed rods 1201. An electric push rod 1203 is fixedly connected to the middle of the upper surface of the fixed plate 1202. The electric push rod 1203 can drive the mounting plate 1204 to move up and down, so as to realize the contact and separation of the detection electrode 1205 with the positive and negative electrodes of the battery.

[0027] Furthermore, the output end of the electric push rod 1203 passes through the bottom surface of the fixed plate 1202 and is fixedly connected to the mounting plate 1204. Two limit rods 1206 are fixedly connected to the upper surface of the mounting plate 1204. The limit rods 1206 are slidably connected to the fixed plate 1202 through guide sleeves. Two detection electrodes 1205 are fixedly connected to the bottom of the mounting plate 1204. The two detection electrodes 1205 are connected to the PLC controller 2 through wires. The detection electrodes 1205 can contact the positive and negative terminals of the battery and transmit the battery's electrical signal to the PLC controller 2, providing key data for battery detection.

[0028] Working principle: Under the action of the return spring 1107, the ejector plate 1105 is in the initial position on the right side, and the output end of the servo cylinder 1109 is in the extended state. The operator or external robotic arm places the battery to be tested on the left side of the ejector plate 1105, with the side of the battery aligned with the edge of the positioning block 4. The PLC controller 2 sends a command to the electric push rod 1203, which drives the mounting plate 1204 to move downward along the limit rod 1206. The detection electrode 1205 contacts the positive and negative terminals of the battery. The electric push rod 1203 has a built-in displacement sensor to ensure accurate electrode pressing stroke and avoid excessive pressure that could damage the battery. The detection electrode 1205 transmits the battery electrical signal to the PLC controller 2 through wires. The built-in detection program of PLC controller 2 performs real-time analysis of parameters such as voltage, capacity, and internal resistance. After the detection is completed, the detection electrode 1205 is disconnected from the battery electrode. PLC controller 2 sends an instruction to servo motor 10 according to the detection result: if it is a good product, servo motor 10 drives rotating shaft 8 to rotate 90 degrees counterclockwise, and the left port of guide plate 9 is aligned with good product discharge slot 5; if it is a defective product, guide plate 9 does not rotate and is aligned with defective product discharge slot 6. The piston rod of servo cylinder 1109 retracts, pulling connecting plate 1108 to drive guide rod 1103 to move to the left. The ejector plate 1105 then pushes the battery into discharge port 3 and guides it into good product discharge slot 5 or defective product discharge slot 6 through guide plate 9.
