[0038] The embodiments of the present application provide a method, system, device and medium for automatically assembling a battery cover, thereby improving the efficiency and quality of battery cover assembly and reducing the cost of battery cover assembly.

[0039] The overall idea of ​​the technical solution in the embodiments of the present application is as follows: the operation of the conveyor belt, camera, and robot are automatically controlled by PLC, thereby automatically conveying and assembling the battery cell covers, eliminating the need for manual material sorting and assembly, reducing site occupancy, thereby improving the efficiency and quality of battery cell cover assembly, and reducing the cost of battery cell cover assembly.

[0040] Example 1

[0041] This embodiment provides a method for automatically assembling a battery cover. Figure 1 As shown, the following steps are included:

[0042] Step S1: After receiving the assembly instruction sent by the industrial computer, the PLC immediately starts the conveyor belt through the Profinet bus to transport and cache the battery cell covers, and discharges the battery cell aluminum shells based on the cached number of battery cell covers;

[0043] Step S2: The PLC uses a camera to visually locate the aluminum shell of the battery cell and generates a positioning result;

[0044] The visual positioning specifically comprises: capturing a photo of the cell cover through a camera, capturing four sides of the cell cover from the photo, fitting a diagonal line through the four sides to obtain a center coordinate, obtaining an offset angle based on the difference between the diagonal angle and a reference angle carried in the cell cover dimensions, and generating a positioning result based on the center coordinate and the offset angle;

[0045] Step S3: Based on the positioning result, the PLC controls the robot via MOODBUS TCP to sequentially grab the battery cell covers from the buffering table and automatically assemble them onto the battery cell aluminum shells;

[0046] Step S4: The PLC generates an assembly report and uploads it to the industrial computer. The industrial computer stores the received assembly report and displays the assembly report through the HMI.

[0047] The step S1 is specifically as follows:

[0048] After the PLC receives the assembly instruction sent by the industrial computer, which includes at least the assembly quantity, battery cover model, and battery cover size, it immediately starts the conveyor belt to transport the battery cover. After the battery cover is transported to the module grabbing position, the battery cover is grabbed to the cache table by the module servo and stored in sequence from the first position to the tenth position of the cache table. The PLC controls the operation of the blocking cylinder based on the cache quantity of the battery cover on the cache table, and then discharges the battery aluminum shell.

[0049] The step S2 is specifically as follows:

[0050] The PLC uses the camera to take real-time photos of the aluminum shell of the battery cell below. While shooting, the camera sends a shooting signal to the robot. The robot latches the encoder value transmitted by the encoder during the current shooting. At the same time, the camera transmits the relative coordinate position of the battery cell aluminum shell relative to the conveyor belt to the robot. The robot stores the received aluminum shell photos, encoder values ​​and relative coordinate position stacks, and generates positioning results based on the aluminum shell photos, encoder values ​​and relative coordinate positions.

[0051] The step S2 further includes:

[0052] The PLC uses a camera to count the cell covers cached on the cache table to obtain a counting result, controls the operation of the blocking cylinder based on the counting result, and then adjusts the caching speed of the cell covers to match the assembly speed of the cell covers.

[0053] The step S4 is specifically as follows:

[0054] The PLC generates an assembly report containing at least the assembly time, cell cover model, cell cover size, and cell cover number. The assembly report is encrypted using a national secret algorithm and uploaded to the industrial computer. The cell cover number is obtained by scanning the cell cover label with a camera. Encrypting the assembly report using a national secret algorithm before uploading prevents the assembly report from being stolen in plain text during transmission, greatly improving the security of the assembly report transmission.

[0055] The industrial computer stores the received assembly report, decrypts it using a national encryption algorithm, and displays it on the HMI. The report is then distributed and backed up to a cloud server. By distributing the backup to the cloud server, if the locally stored report is lost, it can be restored through the cloud server, further ensuring the security of the report.
