Description

[0002] With the continuous development of society, the application of various intelligent electronic devices is becoming more and more widespread, and the demand for lithium batteries is also increasing. In the existing production process of soft-pack lithium batteries (square), a transfer device is required to adjust the position of lithium batteries and transfer the process flow so that they pass through different production stages.

[0003] The existing transfer device generally adopts an adsorption structure. The reference Chinese patent document announcement number is CN205488178U. The patent name is a solar cell string adsorption mechanism. The technical solution discloses "an adsorption tube body 1, a vacuum chamber, a pair of cavity end covers 2, a vacuum chamber connector 3, at least one pair of interfaces 4, at least one pair of vacuum suction cups 5, a mechanism rotating connecting plate 6, the adsorption tube body 1 is a rectangular parallelepiped; the vacuum chamber is arranged in the adsorption tube body 1; the cavity end cover 2 is used to seal the vacuum chamber, the vacuum chamber connector 3 is arranged on the adsorption tube body 1 and connected to the vacuum chamber; the vacuum chamber connector 3 is used to evacuate the vacuum chamber; each pair of interfaces 4 is respectively arranged on both sides of the adsorption tube body 1 and along the length of the adsorption tube body 1. At least one pair of vacuum suction cups 5 is arranged on each side of the adsorption tube body 1, and each pair of vacuum suction cups 5 is respectively installed on both sides of the adsorption tube body 1 and arranged along the long side of the adsorption tube body 1; wherein, each of the vacuum suction cups 5 is provided with a suction port, and each of the suction port corresponds to one of the interfaces 4, and the interfaces 4 are connected to the suction port through a sealing tube; in addition, a mechanism rotation connecting plate 6 is also provided, which is installed in the middle position of the adsorption tube body 1 for connecting to an external rotating device. Although this technical solution can perform multi-station adsorption work, it has the problem of difficult to control the downward pressure when rotating to press down and adsorb lithium batteries. If the downward pressure is too small, it cannot be completely adsorbed. If the downward pressure is too large, the battery will collide and cause deformation of the battery, which is not conducive to improving production quality.

[0004] Therefore, how to achieve the adsorption of soft-pack batteries while buffering the downward pressure is the main technical problem currently faced by technicians. Utility Model Content
