Description

Technical Field

[0001] This utility model belongs to the field of lithium-ion battery technology, specifically relating to a novel formation negative pressure suction nozzle tooling. Background Technology

[0002] In lithium battery manufacturing, the formation process is one of the key steps. It involves applying a specific voltage to the battery cell for initial charging activation, directly impacting the battery's final performance and quality. During this process, the electrolyte is discharged through the needle bed nozzle under negative pressure. This can easily lead to electrolyte residue crystallizing and depositing on the inner wall of the nozzle, causing process abnormalities such as nozzle flow channel blockage and negative pressure system failure. These issues severely affect continuous production and battery quality consistency. Therefore, regularly cleaning and replacing the negative pressure nozzle is essential to ensure the stable operation of the formation process.

[0003] Currently, the industry has various negative pressure nozzle removal devices and related tooling. For example, a patent (CN202421174510.6) proposes a nozzle removal tooling that uses an electromagnet as a power source. Although it has a simple structure and low cost, it suffers from poor removal force stability and the tendency for nozzles to fail to be removed. Another patent (CN202420044417.7) uses electromagnetic adsorption to drive a lifting platform for nozzle removal, but it also suffers from inaccurate removal force control and insufficient reliability. In addition, there is a multi-channel tooling that adopts a step-by-step removal strategy (CN202322462439.3), which improves work efficiency to some extent, but still suffers from complex positioning and long operation time. There is also a solution that relies on the tooling's own weight to achieve removal (CN202321189088.7), which, although simple in structure, significantly increases the load on the stacker crane, which is not conducive to the long-term stable operation of the equipment.

[0004] In summary, existing negative pressure nozzle removal fixtures generally suffer from problems such as inaccurate removal force control, complex structure, poor adaptability, increased equipment load, or insufficient reliability, making it difficult to meet the requirements of efficient, stable, and automated lithium battery production. Therefore, there is an urgent need for a negative pressure nozzle removal fixture with a reasonable structure, stable removal force, strong compatibility, and easy integration into automated control to improve the overall efficiency and reliability of the formation process.

[0005] The purpose of this patent is to provide a novel chemically formed negative pressure nozzle removal tooling that can actively and stably remove the negative pressure nozzle, automatically detect the removal result, and is compatible with nozzles of different specifications.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a novel forming negative pressure suction nozzle tooling, comprising: a tooling base plate, a tooling enclosure plate disposed on the tooling base plate; the tooling base plate is provided with a drive mechanism for providing removal power, a lifting beam driven by the drive mechanism to perform lifting and lowering movements, a gripper bracket connected to the lifting beam, and a suction nozzle removal gripper mounted on the gripper bracket for gripping the suction nozzle.

[0007] Preferably, the drive mechanism includes a drive motor and a lifting screw driven by the drive motor; the lifting beam is threadedly engaged with the lifting screw via a lifting nut.

[0008] Preferably, the number of drive motors and lifting screws is two sets, symmetrically arranged in the middle of the tooling.

[0009] Preferably, the lifting beam is slidably connected to the tooling body by removing the lifting slide rail.

[0010] Preferably, the gripper bracket is slidably connected to the lifting beam via a gripper adjusting slide rail.

[0011] Preferably, the tooling base plate is also provided with a nozzle collection box for collecting the removed nozzles.

[0012] Preferably, the bottom of the tooling base plate is provided with an automatic plug-in power supply and communication port.

[0013] Preferably, it also includes a removal detection sensor for detecting whether the nozzle has been successfully removed.

[0014] Preferably, the removal detection sensor is a through-beam photoelectric sensor, with its transmitter and receiver mounted on the lifting block via sensor adjustment rails.

[0015] Preferably, the tooling base plate is also provided with a lifting block for contacting the warehouse lifting platform and a position adjustment scale for adjusting the position of the gripper bracket.

[0016] The beneficial effects of this utility model are as follows: The novel chemical formation negative pressure suction nozzle tooling provided by this patent achieves active, stable and controllable suction nozzle removal by adopting a motor-driven screw structure. It effectively avoids problems such as unstable removal force, suction nozzle residue and high equipment load that occur in traditional electromagnetic adsorption or gravity-based removal methods. It significantly improves the success rate and reliability of suction nozzle removal, while reducing the load requirements on stacker cranes and supporting equipment, and improving overall production efficiency and equipment service life.

[0017] This tooling integrates automatic power supply and communication interfaces, enabling automatic power supply and data feedback during the lifting process without manual intervention, significantly reducing operational complexity and failure rate.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixed connection," and "fixed connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings and preferred embodiments.

[0024] This utility model discloses a novel fixture for removing negative pressure suction nozzles during chemical formation, comprising a lifting screw 1, a drive motor 2, a gripper bracket 3, a nozzle removal gripper 4, a lifting stop 5, a position adjustment scale 6, a nozzle collection box 7, an automatic plug-in power supply and communication port 8, a gripper adjustment slide rail 9, a lifting beam 10, a removal lifting slide rail 11, a removal detection sensor 12, a sensor adjustment slide rail 13, and a sensor bracket 14. The gripper bracket 3 is connected to the lifting beam 10 via a slider and can move laterally along the gripper adjustment slide rail 9 to accommodate nozzles with different spacings. The lifting beam 10 is connected to the motor screw via a lifting nut and is driven by the drive motor 2, allowing it to move vertically along the removal lifting slide rail 11. The removal detection sensor 12 is mounted on the sensor adjustment slide rail 13 via the sensor bracket 14, and its detection position is adjustable. An automatic plug-in power supply and communication port 8 is located at the bottom of the fixture for connecting to a storage lifting platform to obtain power and communicate.

[0025] In practice, the stacker crane first transports the tooling to the target assembly location. The assembly location's lifting platform rises, aligning its interface with the automatic plug-in power and communication port 8 at the bottom of the tooling, supplying power to the tooling and establishing a signal connection. The platform continues to lift, bringing the lifting stop 5 on the tooling into contact with the needle bed above the assembly location. At this point, the suction nozzle removal gripper 4 engages with the negative pressure suction nozzle 15.

[0026] The drive motor 2 starts, and through the motor screw and lifting nut, it drives the lifting beam 10 to move downward along the removal lifting slide rail 11, thereby causing the gripper bracket 3 and the suction nozzle gripper 4 to move downward, removing the suction nozzle 15 from the needle bed. The removed suction nozzle falls into the suction nozzle collection box 7 through the hole on the gripper bracket 3. The removal detection sensor 12 detects in real time whether the suction nozzle has been successfully removed and feeds the signal back to the control system through the communication interface.

[0027] For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
