[0032] Embodiment 1:
[0033] This embodiment provides a solid-state battery detection device, which includes a transmission system 2, a robotic arm 1, a central processing unit 5, an image acquisition module 3 and a bracket 8.
[0034] The image acquisition module 3 is arranged on the bracket 8. The image acquisition module 3 includes a solid-state battery surface image acquisition module 11 for acquiring the surface image of the solid-state battery and a solid-state battery internal image acquisition module 12 for acquiring the internal structure image of the solid-state battery. The solid-state battery internal image acquisition module 12 adopts an X-ray image acquisition module.
[0035] The central processing unit 5 includes a housing, on which a display module 20, a first data interface 13, a second data interface 14, a first control interface 22 and a second control interface 23 are arranged.
[0036] The first data interface 13 is used to connect to the solid-state battery surface image acquisition module 11; the second data interface 14 is used to connect to the solid-state battery internal image acquisition module 12.
[0037] The first control interface 22 is used to connect to the robotic arm 1; the second control interface 23 is used to connect to the alarm 7.
[0038] A control circuit board is arranged in the housing. On the control circuit board, there are a processing module 10, an image feature extraction module 16, an image comparison module 17, an image storage module 18, a counting module 19, a wireless communication module 9, and a control port 21 and a data port 15. Among them, both the control port 21 and the data port 15 adopt multi-hole sockets. The control port 21 is connected to the first control interface 22 and the second control interface 23 through a wire with a pin-type plug. The data port 15 is also connected to the first data interface 13 and the second data interface 14 through a wire with a pin-type plug.
[0039] Among them, the connection between the first control interface 22 and the second control interface 23 and the control port 21, and the connection between the first data interface 13 and the second data interface 14 and the data port 15 can be plugged in the corresponding positions according to the actual situation.
[0040] The control circuit board is also provided with a connection circuit, which connects the processing module 10 with the image comparison module 17, the wireless communication module 9, the image storage module 18, the counting module 19, the image feature extraction module 16, the control port 21 and the data port 15. The connection circuit also connects the image comparison module 17 with the image feature extraction module 16, and the image feature extraction module 16 with the data port 15, thereby realizing the connection between the image feature extraction module 16 and the solid-state battery surface image acquisition module 11 and the solid-state battery internal image acquisition module 12.
[0041] Among them, the image storage module 18 is used to pre-store the standard image features of the solid-state battery surface and the standard image features of the solid-state battery internal structure.
[0042] The image feature extraction module 16 is used to extract the image features of the solid-state battery surface collected by the solid-state battery surface image acquisition module and the image features of the solid-state battery internal structure collected by the solid-state battery internal image acquisition module.
[0043] The image comparison module 17 is used to compare the extracted image features with the standard image features and generate a comparison result. Specifically, the image features of the solid-state battery surface extracted are compared with the pre-stored standard image features of the solid-state battery surface to generate a first comparison result, and the image features of the solid-state battery internal structure extracted are compared with the pre-stored standard image features of the solid-state battery surface to generate a second comparison result. The first comparison result includes a first similarity; the second comparison result includes a second similarity.
[0044] The processing module 10 is used to control the robotic arm 1 and the alarm 7 according to the comparison result. Specifically, if both the first similarity and the second similarity respectively reach the preset conditions, for example, the first similarity is higher than 99.1% and the second similarity is higher than 98%, then the robotic arm 1 and the alarm 7 are controlled not to perform any actions. If any one of the first similarity and the second similarity does not meet the preset requirements, it is considered that the solid-state battery is defective. The processing module controls the robotic arm 1 to clamp the solid-state battery into the battery box 6, controls the counting module 19 to count, and displays it on the display module 20, so as to facilitate the staff to determine whether the number of solid-state batteries clamped by the robotic arm is correct. At the same time, control the alarm to give an alarm and store the image of the collected solid-state battery into the image storage module.
[0045] The wireless communication module 9 is used to communicate with the outside to remotely read the quantity recorded in the counting module, so as to remotely verify the number of defective batteries and view the images of the defective batteries. Among them, the wireless communication module uses a zigBee wireless communication module.
[0046] When this embodiment is in use, the image acquisition module acquires images of each solid-state battery transmitted by the transmission system. The images include the surface images and the internal structure images of the solid-state batteries. The image feature extraction module extracts the surface image features of each solid-state battery and the internal image features of the internal structures of the solid-state batteries. The comparison module compares the extracted surface image features with the pre-stored standard surface image features to generate a first result, i.e., a first similarity, and compares the extracted internal image features with the pre-stored standard internal image features to generate a second comparison result, i.e., a second similarity. The processing module controls according to the first similarity and the second similarity. Specifically, if any one of the first similarity and the second similarity does not meet the preset conditions, it is considered that there is a defect in the solid-state battery. The processing module controls the robotic arm to clamp the defective solid-state battery into the battery box, controls the counting module to count and display the counting result on the display module, and controls the alarm to give an alarm once. At the same time, the images of the defective solid-state batteries collected are stored in the image storage module for the staff to read and view later.
[0047] The staff can also read the counting result in the central controller and the images stored in the image storage module, i.e., the images of the defective solid-state batteries, through the wireless communication module.
[0048] In this embodiment, by using the image acquisition module to acquire images of solid-state batteries, extract image features, and compare the extracted image features with the standard image features, it is determined whether there are defects in the solid-state batteries according to the comparison results. When there are defects, the robotic arm is controlled to clamp the defective solid-state batteries into the battery box. The whole process does not require manual participation, which helps to implement a unified detection standard, avoid missed detection, and improve the detection efficiency.
[0049] At the same time, counting and displaying the number of defective solid-state batteries helps to quickly determine the number of defects.
