Technical Field

[0001] The utility model relates to the technical field of PACK battery pack production, in particular to an automatic box-entering fixture for square battery core modules based on a CTP process. Background Art

[0002] With the rise and rapid development of new energy, the automotive power battery manufacturing industry has also developed rapidly, and the demand for PACK battery packs has also increased day by day. The traditional PACK battery pack assembly process is to shape and beat steel strips to form modules, and then put them into boxes and stack them into PACK battery packs. In order to simplify the process, the CTP process is introduced. The CTP process directly assembles the battery cells into boxes to obtain PACK battery packs, which simplifies the production process and improves production efficiency.

[0003] However, under the traditional CTP process, the battery cells need to be manually transported into boxes, which has disadvantages such as high work intensity, low boxing efficiency, and poor boxing consistency. Therefore, how to provide an automatic boxing fixture for square battery modules based on the CTP process to improve the efficiency and quality of square battery modules in boxing has become a technical problem that needs to be solved urgently. Summary of the invention

[0070] Working principle of this utility model:

[0071] The robot arm (not shown) is connected to the box entry fixture 100, and the box entry fixture 100 is lowered to the grasping position. The square battery cell module 6 is pressurized to 3-5mm smaller than the box entry size through the pressurizing and shaping mechanisms 4 on both sides.

[0072] After the robot links the box entry fixture 100 to grab the square battery cell module 6 and rises to a height that is detached from the tray (not shown) loaded with the square battery cell module 6, the bottom of the square battery cell module 6 is held by the bottom-protecting anti-falling mechanism 5; after the robot moves the square battery cell module 6 to the top of the box body (not shown) and performs visual positioning, the bottom-protecting anti-falling mechanism 5 is opened, and the robot continues to drive the square battery cell module 6 to descend until the limit position of the box entry fixture 100.

[0073] Close the vacuum sponge suction cup assembly 32, and the pressing mechanism 2 pushes the pressing plate 24 with a downward pressure of 20000N to press the entire square battery cell module 6 down to fit tightly against the bottom of the box. During the entire process, the downward pressure and the downward pressure size are fed back by the first pressure sensor 25 and the servo pressure cylinder 21 to ensure that the flatness error of the battery cell pole surface of the entire square battery cell module 6 is less than or equal to 0.2mm. Finally, the servo pressure cylinder 21 and the pressure shaping mechanisms 4 on both sides are released and reset, and the robot is reset to complete the entire square battery cell module 6 box-entry process.
