Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a rechargeable battery formation device. Background Art

[0002] With the widespread application of rechargeable batteries in portable electronic devices, electric vehicles, energy storage systems, and other fields, the importance of battery manufacturing processes has become increasingly prominent. Among them, the battery formation process is a key part of the battery manufacturing process. Battery formation refers to the process of charging and discharging the battery during the battery production process to gradually develop stable electrochemical properties in the active materials. It is one of the key steps in battery production.

[0003] During the battery formation process, after the battery is placed in the restraint tray, pressure needs to be applied to the side of the battery. This pressure generally reaches 3-10 tons, and then the battery is charged and discharged. Among the current restraint trays, some use mechanical structures to apply rigid mechanical pressure to the battery, while some restraint trays use airbags as partitions in the restraint space. After the airbags are inflated, they apply flexible pressure to the battery. Restraint trays with airbag structures can adapt to batteries of different thicknesses and are therefore widely used. Among them, when using an airbag restraint tray, the airbags need to be charged and discharged.

[0004] Nowadays, various operation steps in battery formation are generally completed through automated structures. However, for the connection operation of the air nozzle and the inflation connector on the airbag, an operating lever is generally used to drive the inflation connector and the air nozzle to make hard contact. In order to avoid damage to the air nozzle and the inflation connector due to excessive contact pressure during the contact process, higher requirements are placed on the motion control accuracy of the operating lever, which increases the complexity and cost of the formation control system. Moreover, once the control program deviates, the air nozzle and the inflation connector will be damaged, and the fault tolerance rate is low. Utility Model Content

[0057] 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 embodiments and the accompanying drawings.

[0058] This embodiment discloses a rechargeable battery formation device for automated operation in a rechargeable battery formation process, such as Figures 1 to 3 The device includes a frame 100, a lifting mechanism 300, a restraint tray 9, and an automatic inflation and deflation mechanism S.

[0059] like Figures 4 to 7 The restraint tray 9 is provided with a plurality of baffles 90. The gaps between two adjacent baffles 90 form a restraint space 93 for loading rechargeable batteries. The baffle 90 includes a frame 91 and an air bag 92 embedded in the frame 91. The air bag 92 can be extended and retracted under the action of internal air pressure to change the size of the restraint space 93. The restraint tray 9 is also provided with a gas nozzle Q (such as Figure 26 When the airbag 92 is inflated, lateral pressure is applied to the battery located in the restraint space 93 . The magnitude of the lateral pressure can be adjusted by adjusting the air pressure level in the airbag 92 .

[0060] It should be noted that the valve nozzle Q, also called the valve core, is a commonly used device in this field, and its structure and working principle will not be described in detail.

[0061] like Figures 10 to 12 The frame 100 provides a supporting carrier, and a conveying mechanism 200 is provided on the frame 100 . The conveying mechanism 200 is used to receive or output the restraint tray 9 .

[0062] The lifting mechanism 300 includes a lifting driver 301 and a bracket 302 connected to the lifting driver 301 . The bracket 302 is used to lift the restraint tray 9 on the conveying mechanism 200 to move up and down.

[0063] like Figure 1 and Figure 2 The automatic inflation and deflation mechanism S includes a motion mechanism S1 and an air port connector S2 connected to the motion mechanism S1.

[0064] like Figures 13 to 17 The gas port connector S2 includes a connection base 4 and a docking head 1 mounted on the connection base 4. The docking head 1 is used to dock with the gas nozzle Q to provide airflow to or receive airflow from the gas nozzle Q. The connection base 4 is mounted on a motion mechanism S1, which is used to move the connection base 4 toward or away from the gas nozzle Q to allow the docking head 1 to dock or detach from the gas nozzle Q. An elastic structure is provided between the docking head 1 and the connection base 4 to enable adaptive adjustment of the contact pressure between the docking head 1 and the gas nozzle Q.

[0065] In this embodiment, an airbag 92 is used in the restraint tray 9 as a barrier 90 to adapt to batteries of different thicknesses. In addition, the automatic inflation and deflation mechanism S includes a motion mechanism S1 and a gas port connector S2. The motion mechanism S1 drives the gas port connector S2 to approach or move away from the gas nozzle Q to complete the automatic docking or separation of the docking joint 1 and the gas nozzle Q on the gas port connector S2, and the contact pressure between the docking joint 1 and the connecting base 4 is adaptively adjusted, thereby effectively reducing the control accuracy of the docking joint 1, which not only reduces the implementation cost of the formation device, but also effectively avoids damage to the gas nozzle Q and the docking joint 1 due to excessive contact pressure between the gas nozzle Q and the docking joint 1.

[0066] like Figures 4 to 9 Each air bag 92 in the restraint tray 9 is connected to the guide plate 94, and the guide plate 94 is connected to the external air port connector S2 through the only air nozzle Q provided thereon. In this way, when using the restraint tray 9, you only need to complete the installation of the air nozzle Q, thereby effectively improving the operational convenience of the restraint tray 9.

[0067] In addition, the frame 91 of the barrier 90 is engaged with the restraint tray 9 , thereby facilitating installation or removal of the barrier 90 .

[0068] On the other hand, an air path connector 95 communicating with the internal space of the airbag 92 is provided on the frame 91 at one end of the partition 90, and a groove 940 communicating with the cavity is provided on the guide plate 94. The groove 940 is used to accommodate the air path connector 95. Through the cooperation between the air path connector 95 and the groove 940, the cavity in the guide plate 94 is connected with the airbag 92, thereby making the airbag 92 and the guide plate 94 seamlessly connected, saving installation space.

[0069] Furthermore, a sealing ring 96 is provided between the air path connector 95 and the groove 940 , thereby effectively improving the air tightness between the airbag 92 and the guide plate 94 .

[0070] On the other hand, a detachable card holder 97 is also provided in the restraint space 93. The card holder 97 has an overall U-shaped structure, including a base plate 970 and two side plates 971 connected to the base plate 970. The base plate 970 is used to carry rechargeable batteries, and the distance between the two side plates 971 is adapted to the rechargeable batteries.

[0071] By setting the card tray 97, card trays of different sizes can be selected according to the width of different types of batteries. Thus, when the battery model changes, only the card tray 97 needs to be replaced without redesigning the restraint tray 9.

[0072] Furthermore, the card tray 97 is engaged and connected with the restraint tray 9 to facilitate replacement of the card tray 97 .

[0073] The top of the side panels 971 of the two card holders 97 is provided with a lug 972 extending away from the area between the two side panels 971, and a T-shaped operating portion 973 is provided on the lug 972. The setting of the operating portion 973 makes it easy to install or remove the card holder 97, effectively improving the user experience.

[0074] On the other hand, Figures 13 to 18 The motion mechanism S1 includes a base 80, a telescopic driver 83 and a support frame 81 connected to the telescopic driver 83, and the support frame 81 is slidably connected to the base 80.

[0075] Specifically, the base 80 and the support frame 81 are connected via a first sliding mechanism 82, and a telescopic actuator 83 is connected to the support frame 81. Based on the first sliding mechanism 82, the telescopic actuator 83 can drive the support frame 81 to reciprocate along a first direction F. In practice, the first direction F is a direction toward or away from the air nozzle Q.

[0076] The connection base 4 is connected to the support frame 81 through a mounting frame 5 .

[0077] The butt joint 1 is provided with a first air passage 14 for communicating with the air nozzle Q. The butt joint 1 is also connected to the connection base 4 via a connection pipe 3, and the connection pipe 3 is also sheathed with a first elastic member k1 serving as an elastic structure between the butt joint 1 and the connection base 4.

[0078] The connecting pipe 3 supports the dynamic change of the distance between the butt joint 1 and the connecting base 4 .

[0079] By means of the first elastic member k1 , the docking head 1 can move toward the connecting base 4 along the first direction F with damping.

[0080] A third air channel 43 is provided in the connection base 4 , and the connection pipe 3 connects the first air channel 14 and the third air channel 43 .

[0081] An air pipe connector 70 communicating with the third air channel 43 is provided on the outside of the connection base 4 , and the air pipe connector 70 is used to receive or discharge airflow.

[0082] In this embodiment, when it is necessary to inflate the airbag 92 within the restraint tray 9, the external air source is connected to the air pipe connector 70 on the air port connector S2, and the telescopic actuator 83 is activated. The telescopic actuator 83 drives the air port connector S2 toward the air nozzle Q via the support frame 81. When the docking joint 1 contacts the air nozzle Q, the support frame 81 continues to move, allowing the docking joint 1 and the air nozzle Q to be tightly docked together to prevent air leakage. The airflow output by the air source then enters the third air channel 43 through the air pipe connector 70, then flows into the first air channel 14, and ultimately enters the airbag via the docking joint 1 and the air nozzle Q. Similarly, when it is necessary to deflate the airbag, the docking joint 1 is also tightly docked with the air nozzle Q. The airflow in the airbag enters the air pipe connector 70 via the air nozzle Q, the first air channel 14, and the third air channel 43, and is ultimately discharged through the air pipe connector 70.

[0083] During the contact process between the docking joint 1 and the air nozzle Q, due to the action of the connecting tube 3 and the first elastic member k1, the docking joint 1 moves toward the connecting base 4 with damping, thereby providing a tightly connected contact pressure for the docking joint 1 and the air nozzle Q, while avoiding damage to the docking joint 1 and the air nozzle Q due to excessive contact pressure. Thus, the error margin of the moving distance of the air port connector S2 is improved through the physical structure, and the requirements for the control accuracy of the telescopic drive 83 are reduced.

[0084] On the other hand, Figures 18 to 25 The connecting tube 3 is connected to the connecting base 4 via a connecting shaft 2. A second air passage 22 is provided within the connecting shaft 2. Through the connecting tube 3, the second air passage 22 connects the first air passage 14 with the third air passage 43. When the docking joint 1 is docked with the gas nozzle Q, the docking joint 1 approaches the connecting shaft 2 with a damped force. In this embodiment, the provision of the connecting shaft 2 facilitates docking of the connecting tube 3 with the connecting base 4, effectively improving the operational stability of the gas port connector S2.

[0085] Furthermore, the docking joint 1 includes a first end 10 and a second end 11, the first end 10 has a receiving groove 12, the receiving groove 12 is used to receive and accommodate the air nozzle Q, and a pin 13 for abutting the air nozzle Q is provided in the receiving groove 12. The first air duct 14 is provided in the pin 13, and the first air duct 14 extends from the receiving groove 12 to the second end 11. The first air duct 14 has a first opening portion 140 located in the receiving groove 12 and a second opening portion 141 located at the second end 11.

[0086] When the docking joint 1 and the air nozzle Q are close to each other and the air nozzle Q enters the receiving groove 12, the ejector pin 13 in the receiving groove 12 presses against the air nozzle Q, and the air flow channel in the air nozzle Q is pushed open by the pressing force, so that the air flow in the first air channel 14 enters the air nozzle Q or the air flow in the air nozzle Q is discharged into the first air channel 14.

[0087] The connecting shaft 2 includes a third end 20 and a fourth end 21 , one end of the connecting pipe 3 is connected to the second end 11 of the docking joint 1 , the other end of the connecting pipe 3 is connected to the third end 20 of the connecting shaft 2 , and the fourth end 21 of the connecting shaft 2 is connected to the connecting base 4 .

[0088] Furthermore, the connecting base 4 includes a fifth end 40 and a sixth end 41 . The fifth end 40 is provided with a connecting hole 42 for connecting with the fourth end 21 of the connecting shaft 2 . The third air channel 43 is connected to the second air channel 22 through the connecting hole 42 .

[0089] On the other hand, the connecting tube 3 is a flexible tube body so that the length of the connecting tube 3 can be changed. For example, the connecting tube 3 can be made of PE material or silicone material, and a corrugated tube can also be used as the connecting tube 3.

[0090] On the other hand, a transition portion 15 is provided between the first end 10 and the second end 11. The diameters of the first end 10, transition portion 15, and second end 11 decrease in sequence. The second end 11 extends into the connecting tube 3 and is sealed to the inner wall of the connecting tube 3. Since the second end 11 also terminates the first air passage 14, inserting the second end 11 into the connecting tube 3 effectively ensures airtightness between the first air passage 14 and the inner cavity of the connecting tube 3.

[0091] Furthermore, a connecting sleeve 6 is sleeved on the outer circumferential wall of the transition portion 15. An open groove 60 surrounding the connecting tube 3 is provided on the end of the connecting sleeve 6 facing the second end 11. A boss 23 is also provided on the outer circumferential wall of the connecting shaft 2, located between the third end 20 and the fourth end 21. One end of the first elastic member k1 abuts the bottom wall of the open groove 60, and the other end of the first elastic member k1 abuts the boss 23. In this embodiment, the provision of the connecting sleeve 6 effectively ensures the installation stability of the first elastic member k1.

[0092] On the other hand, the first air channel 14 includes a first section 142 near the first end 10 and a second section 143 near the second end 11. The diameter of the second section 143 is larger than the diameter of the first section 142. Since the diameter of the second section 143 is larger than the diameter of the first section 142, when air is delivered to the air nozzle Q, the air pressure of the air flow provided to the air nozzle Q can be effectively increased, thereby increasing the air delivery rate.

[0093] Furthermore, the mounting frame 5 is provided with a retaining wall 52. A second elastic member k2 is disposed between the connecting base 4 and the retaining wall 52. The connecting base 4 is connected to the mounting frame 5 via a second sliding mechanism. With the aid of the second sliding mechanism and the second elastic member k2, the connecting base 4 can be moved toward the retaining wall 52 with damping along the first direction F. In this embodiment, the second elastic member k2 further increases the movement margin of the connecting head 1 during the docking process between the connecting head 1 and the gas nozzle Q.

[0094] In the above embodiment, the first sliding mechanism 82 includes a first slide rail 820 and a first slider 821 . The first slide rail 820 is disposed on the base 80 . The first slider 821 is slidably connected to the first slide rail 820 . The frame 81 is connected to the first slider 821 .

[0095] The second sliding mechanism includes a second slide rail 50 and a second slider 51 . The second slide rail 50 is disposed on the mounting frame 5 . The second slider 51 is slidably connected to the second slide rail 50 . The second slider 51 is connected to the connecting base 4 .

[0096] On the other hand, Figure 13 and Figure 14 The support frame 81 is also provided with an air flow transmission network connected to the air pipe joint 70. The air pipe joint 70 receives or discharges air through the air flow transmission network. The air flow transmission network includes an air inlet pipe P1, an exhaust pipe P2 and a pressure relief pipe P2.

[0097] Specifically, the inlet pipe P1, the exhaust pipe P2, and the pressure relief pipe P2 are connected to the air pipe connector 70 on the air port connector S2 via the gas diverter 84. High-pressure air is supplied to the air port connector S2 via the inlet pipe P1, and air received by the airbag 92 is discharged to the air port connector S2 via the exhaust pipe P2. While air is being supplied through the inlet pipe P1, air can also be discharged through the pressure relief pipe P3 to prevent excessive pressure within the air port connector S2.

[0098] On the other hand, Figure 10 The conveying mechanism 200 includes a plurality of conveying rollers 201 arranged at intervals, and a plurality of brackets 302 are arranged in the gaps between the plurality of conveying rollers 201 .

[0099] At the beginning of the formation process, the restraint tray 9 is placed on the conveying roller 201 located at one end of the frame 100, and then the restraint tray 9 is conveyed to the other end of the frame 100 as the conveying roller 201 rolls until the entire restraint tray 9 is located on the frame 100. Next, the lifting drive 301 is started to drive the bracket 302 to move upward, thereby driving the restraint tray 9 to move upward, so that the air nozzle Q on the restraint tray 9 and the docking joint 1 on the air port connector S2 are at the same height. Next, the telescopic drive 83 in the automatic inflation and deflation mechanism S is started to drive the air port connector S2 toward the air nozzle until the docking joint 1 docks with the air nozzle Q. Then, the airbag 92 is inflated to apply pressure to the rechargeable battery in the restraint tray 9. Then, the charging and discharging operations on the rechargeable battery in the restraint tray 9 can be started.

[0100] After the formation process is complete, the telescopic actuator 83 moves the gas port connector S2 backward, separating the docking head 1 from the gas nozzle Q. The lifting actuator 301 then moves the bracket 302 downward, allowing the restraint tray 9 to land back on the conveyor rollers 201. The conveyor rollers 201 are then reversed to transport the restraint tray 9 outward, completing the formation process.

[0101] The above disclosure is only a preferred embodiment of the present invention, and 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.
