[0002] With the wide application of rechargeable batteries in various electronic devices and power tools, the safety and efficiency in the production process have become key issues. Among the multiple links in battery production, the formation process is an important and indispensable step. The formation process refers to converting the active substances inside the battery into available chemical energy through electrochemical reactions, which has a direct impact on the battery performance and lifespan. To ensure the smooth progress of the formation process, after the battery is placed in the restraint tray, pressure needs to be applied to the side of the battery, and this pressure generally reaches 3 - 10 tons, and then the charge and discharge operations are performed on the battery. In current restraint trays, there are those that apply rigid mechanical pressure to the battery through mechanical structures, and there are also some restraint trays that use airbags as partition members for the restraint space, and after the airbags expand, they apply flexible pressure to the battery. For the restraint trays with airbag structures, they can be adapted to batteries of different thicknesses, so they have been widely used.

[0003] However, there are still some deficiencies in the design and use of existing airbag type restraint trays. For example, the air inflation system of the airbag is complex. When in use, each airbag needs to be separately connected to the air charging and discharging link, which is time-consuming and laborious. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an airbag type restraint tray that can be adapted to different specifications of materials and is convenient to operate.

[0005] To achieve the above purpose, the utility model provides an airbag type restraint tray, which includes a support member at the bottom and a surrounding member surrounding the periphery of the support member.

The plurality of partition members extend from the first end to the second end of the accommodation space. In the direction of the first end and the second end, the gaps between two adjacent partition members form restraint spaces for loading materials. The partition member includes a frame and an airbag embedded in the frame. The airbag can perform telescopic movement under the action of internal air pressure to change the size of the restraint space. The surrounding member is further provided with a flow guide plate. A sealed cavity is arranged in the flow guide plate. An air nozzle for air charging and discharging communicated with the cavity is arranged on the outer side of the flow guide plate.

[0020] To describe in detail the technical content, structural features, achieved objectives and effects of the present utility model, the following will be described in detail in conjunction with the implementation manners and with reference to the accompanying drawings.

[0021] This embodiment discloses an airbag-type restraint tray, which is used to hold materials and provide pressure to the materials. For example, it is used for centralized holding of batteries in the battery formation process.

[0022] As Figures 1 to 4 , the restraint tray includes a support member 1 at the bottom and a surrounding member 2 surrounding the periphery of the support member 1. An open accommodation space is formed between the surrounding member 2 and the support member 1. A plurality of spaced-apart partition members 3 are arranged in the accommodation space. The plurality of partition members 3 extend from the first end P1 to the second end P2 of the accommodation space. In the direction of the first end P1 and the second end P2, the gaps between two adjacent partition members 3 form restraint spaces 4 for loading materials. When used in the battery formation process, a plurality of batteries are respectively placed in each restraint space 4.

[0023] The partition member 3 includes a frame 30 and an airbag 31 embedded in the frame 30. The airbag 31 can expand and contract under the action of internal air pressure to change the size of the restraint space 4, so as to adaptively fit materials of different thicknesses.

[0024] The surrounding member 2 is further provided with a deflector 50. A sealed cavity is arranged in the deflector 50. An air nozzle 51 for inflating and deflating, which is communicated with the cavity, is arranged on the outer side of the deflector 50. Each airbag 31 is hermetically communicated with the cavity in the deflector 50.

[0025] In this embodiment, the restraint spaces 4 are formed by a plurality of partition members 3. The partition member 3 is composed of a frame 30 and an airbag 31 embedded in the frame 30. The airbag 31 can expand and contract under the action of internal air pressure, so as to change the size of the restraint space 4 and adapt to different specifications of batteries. When the airbag 31 is inflated, the airbag 31 exerts a lateral extrusion force on the material in contact with it. By adjusting the magnitude of the air pressure in the airbag 31, the extrusion force can be controlled within the target range. In addition, each airbag 31 in the tray is communicated with the deflector 50. The deflector 50 is communicated with the external inflation and deflation link through the only air nozzle 51 arranged thereon. In this way, when using the restraint tray, only the installation work of the air nozzle 51 needs to be completed, thereby effectively improving the operation convenience of the restraint tray.

[0026] In addition, the frame 30 of the partition member 3 is snap - connected to the enclosure member 2, facilitating the installation or disassembly of the partition member 3.

[0027] On the other hand, as Figures 3 to 5 , an air - path connector 6 communicating with the internal space of the airbag 31 is provided on one end frame 30 of the partition member 3, and a groove 52 communicating with the cavity is provided on the deflector 50. The groove 52 is used to accommodate the air - path connector 6. Through the cooperation of the air - path connector 6 and the groove 52, the cavity in the deflector 50 is communicated with the airbag 31, enabling a seamless connection between the airbag 31 and the deflector 50 and saving installation space.

[0028] Furthermore, a sealing ring 7 is also provided between the air - path connector 6 and the groove 52, effectively enhancing the airtightness between the airbag 31 and the deflector 50.

[0029] On the other hand, as Figure 1 and Figure 6 , a detachable carrier 8 is also provided in the restraint space 4. The carrier 8 is integrally U - shaped, including a bottom plate 80 and two side plates 81 connected to the bottom plate 80. The bottom plate 80 is used to carry the material, and the distance between the two side plates 81 is adapted to the material.

[0030] Through the provision of the carrier 8, different - sized carriers 8 can be selected according to the widths of different models of batteries. Thus, when the battery model changes, only the carrier 8 needs to be replaced, without the need to re - design the restraint tray.

[0031] Furthermore, the carrier 8 is snap - connected to the enclosure member 2 to facilitate the replacement of the carrier 8.

[0032] As shown in the figure, at the top of the side plates 81 of the two carriers 8, there are lugs 82 protruding away from the area between the two side plates 81, and a T - shaped operation part 83 is provided on the lugs 82. Through the provision of the operation part 83, it is convenient to install or disassemble the carrier 8, effectively enhancing the user experience.

[0033] Moreover, a hollow part 84 is provided on the bottom plate 80 to facilitate the heat dissipation of the battery.

[0034] The above - disclosed are only the preferred embodiments of the present utility model. Of course, the scope of rights of the present utility model cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present utility model still fall within the scope covered by the present utility model.
