[0002] Lithium-ion batteries, as a rechargeable and clean energy source, are widely used in digital devices, electric vehicles, and other products. The lithium-ion battery manufacturing process includes a formation step, the main function of which is to activate the lithium-ion battery. During formation, lithium-ion batteries expand, therefore, battery restraint trays are used to restrain the batteries and control their thickness.

[0003] In existing technologies, some battery restraint trays use airbags for restraint. Inflating or deflating the airbags expands or contracts, completing the battery restraint and release process. However, currently, the inflation and deflation of the airbags on the tray cannot be controlled stepwise, resulting in poor automatic controllability and low automation. Utility Model Content

The manifold has a pin inside the gas channel that is retractable within the gas channel. The gas pipe connector is used to connect to an external inflation / deflation mechanism.

[0008] A first driving member is disposed on the manifold. The first driving member drives and connects to the manifold, thereby pressing the air nozzle against the air port of the target device to form a sealed air passage.

[0009] A second driving member is disposed on the support component. The second driving member drives the ejector pin, enabling the ejector pin to open or close the switching valve that controls the opening and closing of the air port.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1 to 5 This utility model proposes an automatic inflation and deflation mechanism.

[0031] The automatic inflation / deflation mechanism includes a support component 100 and a manifold 200. The manifold 200 is slidably connected to the support component 100. The manifold 200 has a gas channel 221 inside, which connects to a nozzle 222 and a pipe connector 223. A pin 210 is provided in the gas channel 221 of the manifold 200. The pin 210 is retractably located in the gas channel 221. The pipe connector 223 is used to connect to an external inflation / deflation mechanism. A first drive component 300 is provided on the manifold 200 and drives the manifold 200 to press the nozzle 222 against the air port of the target device to form a sealed air channel. A second drive component 400 is provided on the support component 100 and drives the pin 210 to open or close the switch valve that controls the opening and closing of the air port.

[0032] Specifically, the air nozzle 222 can be a soft rubber nozzle 222, ensuring that a sealed air channel is formed when the soft rubber nozzle 222 is pressed against the air port of the target component. Alternatively, the air nozzle 222 can be of other forms, as long as it ensures that a sealed air channel is formed when the air nozzle 222 is pressed against the air port of the target component. The target component can be a battery restraint tray or other equipment that requires inflation. The opening and closing of the air port by the ejector pin 210 opening the switch valve is a conventional technology and will not be described in detail here. In use, this automatic inflation / deflation mechanism is completed by two parts: the first drive member 300 and the second drive member 400. When it is necessary to inflate the airbag of the battery restraint tray, the first drive member 300 drives the manifold 200 to move, and the air nozzle 222 of the manifold 200 presses against the outer edge of the air port of the target component to form a sealed air channel. By extending and retracting the second drive member 400, the ejector pin 210 is driven to open and close the switch valve air port of the target component, realizing automated control of inflation / deflation. With this configuration, the automatic charging and discharging mechanism can integrate all external intake and exhaust pipes, nozzles 222, and the second drive unit 400 through the manifold 200 and work in conjunction with the first drive unit 300 to complete the automatic charging and discharging operation by means of two power supplies, which can greatly improve battery production efficiency.

[0033] Please see Figures 1 to 3Furthermore, the manifold 200 includes a manifold block 224 and an air intake base 225. The air intake base 225 is slidably connected to the support member 100, and the manifold block 224 is disposed on the air intake base 225. The first driving member 300 drives the air intake base 225, and the manifold block 224 has a gas channel 221. Specifically, the manifold block 224 can be fixed to the air intake base 225 by screws or other means. The first driving member 300 can drive the air intake base 225 to slide on the support member 100 to ensure that the air nozzle 222 can be pressed against the air nozzle 222 on the tray.

[0034] Please see Figure 5 Furthermore, the gas channel 221 includes an interconnected gas intake channel 226 and a gas delivery channel 227. The gas delivery channel 227 connects to the gas intake channel 226, the gas intake channel 226 connects to the gas pipe connector 223, and the gas delivery channel 227 connects to the gas nozzle 222. The ejector pin 210 is retractably disposed within the gas delivery channel 227. Thus, the second driving member 400 can drive the ejector pin 210 to extend and retract within the gas delivery channel 227, enabling the ejector pin 210 to open the gas port. The manifold 224 integrates the various channels and controls the extension and retraction of the ejector pin 210, resulting in a high degree of automation.

[0035] Please see Figure 4 To ensure the airtightness of the manifold 224, an annular groove 410 is further provided in the manifold 224, and a sealing ring 420 is provided in the annular groove 410. The sealing ring 420 is clamped between the manifold 224 and the second drive member 400. In this way, the sealing ring 420 can ensure the installation gap between the manifold 224 and the second drive member 400, ensuring that there is no air leakage between the manifold 224 and the second drive member 400.

[0036] Please see Figures 1 to 3 Furthermore, a guide rail 500 is fixedly connected to the support component 100, and a slider 600 is fixedly connected to the bottom of the air extraction base 225. The slider 600 is slidably connected to the guide rail 500. In this way, the air extraction base 225 can slide on the support component 100 through the adaptation of the guide rail 500 and the slider 600, making the sliding of the air extraction base 225 more stable.

[0037] Please see Figures 1 to 5 Furthermore, the first driving component 300 is a first cylinder, and a cylinder seat 700 is provided on the supporting component 100. The first cylinder is mounted on the cylinder seat 700, and the telescopic rod of the first cylinder drives the air intake base 225. Through the telescopic movement of the first cylinder, the air intake base 225 can be driven to slide back and forth, allowing the air intake base 225 to slide back and forth and move back and forth between the air nozzle 222 pressing against or disengaging from the air port of the target component.

[0038] Please see Figures 1 to 5 Furthermore, the second driving component 400 is a second cylinder, and the telescopic rod of the second cylinder drives the ejector pin 210. In this way, the second cylinder drives the ejector pin 210 to perform telescopic movement, so that the second cylinder can drive the ejector pin 210 to open or close the air port of the target component.

[0039] Please see Figures 1 to 5 Furthermore, one end of the ejector pin 210 has an internal thread, and the telescopic rod of the second cylinder has an external thread. The ejector pin 210 and the telescopic rod of the second cylinder are screwed together by the internal and external threads. This improves the stability of the connection between the ejector pin 210 and the telescopic rod of the second cylinder, and also improves the stability of the screwed connection between the ejector pin 210 and the telescopic rod, ensuring that the second cylinder can drive the ejector pin 210 to extend or retract.

[0040] Please see Figures 1 to 5 Furthermore, there are multiple ejector pins 210, second drive units 400, air nozzles 222, and air delivery channels 227. Multiple second drive units 400 are provided on the air intake base 225, each second drive unit 400 driving and connecting to a corresponding ejector pin 210. Each ejector pin 210 is retractably located within its corresponding air delivery channel 227. With this configuration, a single manifold 224 can simultaneously inflate and deflate multiple air nozzles 222 of a battery restraint tray. Each second drive unit 400 individually drives its corresponding ejector pin 210 to open the air vent of the airbag, enabling control of airbag inflation and deflation.

[0041] Please see Figures 1 to 5 This utility model also proposes a battery production equipment, which includes a battery restraint tray and an automatic charging / discharging mechanism. The specific structure of the automatic charging / discharging mechanism is as described in the above embodiments. Since this battery production equipment adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The battery restraint tray has multiple airbags inside, and each pair of adjacent airbags is used to restrain the battery. The airbags are connected to a manifold, and the manifold is equipped with a switching valve. Specifically, the manifold can be opened by the pin 210 opening the switching valve. At this time, the gas channel 221 connects to the inside of the airbag, and the external charging / discharging mechanism can charge and de-charge the airbag, realizing the expansion or contraction of the airbag, completing the battery restraint and de-restraint actions.

[0042] The above are merely optional embodiments of this utility model and do not limit the patent scope of this utility model. All equivalent structural transformations made based on the contents of this utility model specification and drawings under the utility model concept, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
