[0002] In the battery manufacturing process, sorting and capacity activation are crucial process steps. In order to improve battery production efficiency and product consistency, automated operations have been widely used in modern battery production lines. Especially in the capacity sorting and activation process, accurately and quickly loading and unloading batteries on the corresponding restraint trays is an important part of realizing process automation. However, due to the differences in battery size specifications and the precise requirements for placement on the tray, restraint trays with fixed restraint sizes are gradually being eliminated.

[0003] At present, battery manufacturers tend to use restraint trays based on airbags to apply restraint force. For this reason, the performance and reliability of the inflation and deflation device for inflating and deflation of the restraint tray are crucial. Traditional inflation and deflation devices usually include a fixed air nozzle and a connector. The connector and the air nozzle are rigidly connected, and the connector and the air nozzle are connected by a power system (such as a manipulator). In this way, in order to ensure that the contact pressure between the air nozzle and the connector is appropriate, that is, to ensure close contact between the two without damaging the air nozzle, this puts forward relatively high requirements on the control accuracy of the power system.

[0004] At present, attempts are made to solve the above problems by adding guiding mechanisms or using high-precision drivers, but these solutions are often complex in structure and high in cost, which limits their popularity in practical applications. Summary of the invention

[0005] The purpose of the present invention is to provide a floating type inflation and deflation joint and a restraint tray inflation and deflation device which can effectively ensure accurate docking between an air nozzle and a docking joint and has no special requirements on control accuracy.

[0006] In order to achieve the above object, the present invention provides a floating gas charging and discharging joint, which comprises: A base, comprising a first end and a second end, wherein the first end is provided with a docking joint for connecting to an air nozzle, and an air passage communicating with the docking joint is provided in the base; and a first vent communicating with the air passage is also provided on the base; A fixing seat is connected to the second end of the base through a floating joint so that the base can float in multiple axial directions relative to the fixing seat, and the fixing seat is used to install and fix the base.

[0016] Compared with the prior art, the floating type air-filling and air-discharging joint disclosed in the present invention includes a base and a fixed base, wherein the base and the fixed base are connected by a floating joint, so that when the docking joint on the base docks with the gas nozzle, the base can move slightly left, right, up and down under the action of the docking force to adapt to the position error and contact pressure between the gas nozzle and the docking joint.

[0022] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0023] This embodiment discloses a restraint tray inflation and deflation device, such as Figure 1 The restraint tray P is provided with a plurality of air bags (not shown) for restraining the materials placed therein, and a shunt pipe P1 connected with the plurality of air bags, and a gas nozzle P2 is provided on the shunt pipe P1. Based on this, the inflation and deflation device is used to dock with the gas nozzle P2 to inflate or deflate the plurality of air bags on the restraint tray P through the shunt pipe P1.

[0024] like Figures 1 to 5The inflation and deflation device includes a support frame 1, a support platform 2, a lifting mechanism 4 and a floating inflation and deflation joint 3.

[0025] The support frame 1 is used to place and restrain the pallet P.

[0026] The support platform 2 is arranged above the support frame 1 , and the gas charging and discharging joint 3 is arranged on the support platform 2 . The gas charging and discharging joint 3 includes a base 30 and a fixing seat 31 .

[0027] The base 30 includes a first end D1 and a second end D2. The first end D1 is provided with a docking joint 36 for connecting with the air nozzle P2. The base 30 is provided with an air passage 300 communicating with the docking joint 36. The base 30 is also provided with a first vent 301 communicating with the air passage 300.

[0028] One end of the fixing seat 31 is connected to the support platform 2, and the other end of the fixing seat 31 is connected to the second end D2 of the base 30 through the floating joint 32, so that the base 30 can float in multiple axes relative to the fixing seat 31, and the docking joint 36 extends toward the support frame 1 below.

[0029] The lifting mechanism 4 is connected to the support frame 1 , and is used to drive the support frame 1 to move up and down, so that the air nozzle P2 on the restraint tray P is connected to or separated from the docking head 36 .

[0030] In this embodiment, when the battery is subjected to the capacity separation and discharging operation, the first vent 301 on the charging and discharging gas connector 3 is connected to the gas source by an airflow pipeline. After the restraint tray P is placed on the support frame 1, the support frame 1 is raised by the lifting mechanism 4, so that the gas nozzle P2 on the restraint tray P is close to the docking joint 36, until the docking joint 36 and the gas nozzle P2 are docked together, so as to open the airflow channel in the docking joint 36, so that the airflow in the airway 300 enters the gas nozzle P2, or receives the airflow output by the gas nozzle P2. The matching structure of the docking joint 36 and the gas nozzle P2 in this embodiment belongs to the conventional technology in the field and will not be described here. In addition, the floating joint 32 is also a standard device commonly used in industrial equipment, so its specific structure will not be described in detail.

[0031] When the docking joint 36 on the base 30 docks with the air nozzle P2, under the action of the floating joint 32, the base 30 can move slightly left, right, up, and down under the docking force to adapt to the position error and contact pressure between the air nozzle P2 and the docking joint 36. It can be seen that based on the inflation and deflation joint 3, the air nozzle P2 and the docking joint 36 are flexibly docked, thereby effectively reducing the control accuracy requirements for the two while ensuring the accurate docking between the docking joint 36 and the air nozzle P2.

[0032] On the other hand, the floating joint 32 is connected to the fixing seat 31 via a screw rod 33 to achieve a detachable connection between the floating joint 32 and the fixing seat 31 .

[0033] Furthermore, an elastic member 34 is sleeved on the screw rod 33, one end of the elastic member 34 abuts against the floating joint 32, and the other end of the elastic member 34 abuts against the fixed seat 31. The arrangement of the elastic member 34 provides the base 30 with a moving space along the axis direction of the screw rod 33, thereby further improving the docking margin between the docking joint 36 and the air nozzle P2 in the vertical direction.

[0034] On the other hand, a plurality of gas charging and discharging joints 3 are arranged at intervals on the support platform 2, and the first vents 301 in the plurality of gas charging and discharging joints 3 are respectively connected to the diverter row 5 arranged on the support platform 2 through pipes. The diverter row 5 is also provided with an exhaust port 50 and a gas discharge port 51. Through the arrangement of the diverter row 5, only one air intake pipe needs to be arranged to supply air to the plurality of gas charging and discharging joints 3 at the same time. In addition, through the arrangement of the exhaust port 50 on the diverter row 5, the pressure of the airflow output by the joint 36 can be adjusted according to demand during operation. Through the arrangement of the gas discharge port 51 on the diverter row 5, the gas in the airbag can be conveniently released.

[0035] On the other hand, the base 30 is also provided with a second vent 302 communicating with the airway 300 and an air pressure detector 35 communicating with the second vent 302. Through the provision of the air pressure detector 35, the air pressure of the airway 300 can be accurately controlled to ensure the safety performance of the charging and discharging joint 3.

[0036] On the other hand, the inflation and deflation device in the embodiment of the present invention further includes a plurality of conveying rollers 6 arranged in parallel, with a gap 60 between two adjacent conveying rollers 6, the support frame 1 includes a bottom frame 10 and a plurality of pallets 12 arranged in parallel, and the lifting mechanism 4 is connected to the bottom frame 10. The pallet 12 is connected to the bottom frame 10 through a support rod 11 passing through the gap 60, and each pallet 12 can move up and down in the gap 60. The pallet 12 is used to support the restraining pallet P, and the conveying roller 6 is used to convey the restraining pallet P freely or withdraw from the supporting surface formed by a plurality of pallets 12. In this embodiment, when loading, one side of the restraining pallet P is first placed on the conveying roller 6 located at the edge, and at this time, the bottom frame 10 is driven by the lifting mechanism 4 to perform lifting and lowering movements to control the pallet 12 to be flush with the upper plane of the conveying roller 6 or slightly lower than the upper surface of the conveying roller 6, and then as the conveying roller 6 rotates, the restraining pallet P is placed flat on each pallet 12. When unloading, the conveying roller 6 continues to rotate forward or reversely to move the restraining pallet P out of the supporting surface where each support plate 12 is located. Therefore, through the arrangement of the conveying roller 6, the automatic loading and unloading of the restraining pallet P can be realized.

[0037] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
