A multi-layered hot press mechanism for a battery cell according to an embodiment of the present utility model is described below with reference to fig. 1 to 4.
As shown in fig. 1-4, the multi-layer hot-pressing mechanism for the electric core comprises a hot-pressing driving assembly and a plurality of groups of hot-pressing mechanisms for the electric core, wherein each hot-pressing mechanism for the electric core is stacked along the vertical direction. The hot-pressing driving assembly is positioned above the hot-pressing mechanism of the uppermost layer of the electric core, applies pressure along the stacking direction through the hot-pressing driving assembly and drives the electric core in each electric core hot-pressing mechanism to press and heat. The hot pressing driving assembly is pressed downwards by utilizing the vertically stacked weight assistance of each electric core hot pressing mechanism, so that the mechanism cost can be saved, and the hot pressing efficiency can be improved.
Specifically, the hot pressing driving assembly is provided with a hot pressing push plate and a pressurizing cylinder for driving the hot pressing push plate to press down, the pressurizing cylinder is positioned above the hot pressing push plate, and the pressurizing cylinder presses down all the electric cores in the vertical direction through driving the hot pressing push plate to press down all the electric core hot pressing mechanisms. At least one group of electric core hot pressing mechanisms are stacked in sequence along the vertical direction, the tops of the adjacent electric core hot pressing mechanisms are connected with the bottoms, and the electric core hot pressing mechanism and the hot pressing driving assembly at the uppermost layer drive each electric core hot pressing mechanism to work at the same time.
Wherein, electric core hot pressing mechanism's base top is provided with the indisputable fluoro Long Buping platform of upper and lower activity, and indisputable fluoro dragon cloth platform is used for bearing electric core, and indisputable fluoro dragon cloth platform top is provided with the hot pressboard, goes up the hot pressboard and sets up in the bottom plate one side of electric core hot pressing mechanism above.
Specifically, the teflon cloth platform vertically rises and falls above the bottom of the electric core hot-pressing mechanism, and the projection area of the electric core in the vertical direction is smaller than the bearing area of the teflon cloth platform. The Teflon cloth can withstand high temperatures, and can withstand temperatures as low as-70 ℃ to 260 ℃. Can be used under extreme temperature conditions without losing its physical and chemical properties. And the teflon cloth has a very smooth and non-adhesive surface, so that the sticking of the battery cell and the bottom of the battery cell hot-pressing mechanism can be effectively prevented in the process of pressing and heating the battery cell. The electric core is supported by the Teflon cloth platform to be heated, so that the electric core is easier to separate after the electric core is pressed down and heated.
And the upper hot pressing plate can adopt a whole heating plate, so that the surface of the battery cell can be prevented from being pressed and pressed in the heating process. And when the electric core hot pressing mechanism resets, the electric core is separated from the upper hot pressing plate under the action of gravity, so that the electric core is separated from the electric core hot pressing mechanism. The manipulator is convenient to take out the hot-pressed battery cell from the battery cell hot-pressing mechanism.
In some embodiments of the present utility model, as shown in fig. 1, 3 and 4, a jacking cylinder is disposed on one side of the teflon platform, and the jacking cylinder is used to drive the teflon platform to approach or separate from the base of the electric core hot pressing mechanism.
In a further embodiment, as shown in fig. 1-4, a battery cell hand-changing support plate is respectively arranged at one side of each battery cell hot-pressing mechanism, and the battery cell hand-changing support plate extends between a base of the battery cell hot-pressing mechanism and the iron fluorine Long Buping platform and is used for supporting the iron fluorine dragon cloth platform. Specifically, when the jacking cylinder lifts the iron fluorine Long Buping platform, the cell hand-changing support plate stretches into a gap between the iron fluorine dragon cloth platform and the cell hot-pressing mechanism base from one side of the cell hot-pressing mechanism, and then the lifting cylinder descends, so that the cell hand-changing support plate supports the iron fluorine dragon cloth platform, and the manipulator clamps the cell onto the iron fluorine dragon cloth platform.
In a further embodiment, as shown in fig. 1 and 3, the width of the cell-changing blade is less than the width of the hot cell of the cell hot press mechanism. Specifically, because the width dimension of the battery cell hand-changing supporting plate is smaller than the width of the battery cell, the battery cell clamping jaw of the manipulator can extend into the hot press table to place the battery cell. After the electric core is placed completely, the electric core hand-changing supporting plate slowly retreats out, the jacking air cylinder descends, and the hot-pressing driving assembly drives the upper hot-pressing plates of all electric core hot-pressing mechanisms to press down to hot-press the electric core. After the hot pressing is finished, the upper hot pressing plate is lifted, the lifting cylinder lifts the Teflon cloth platform to lift the battery cell, the battery cell hand-changing supporting plate stretches into a gap between the battery cell hot pressing mechanism base and the Teflon Long Buping table to lift the Teflon cloth platform, then the lifting cylinder descends, and the discharging battery cell clamping jaw of the manipulator stretches into the inner part to clamp the battery cell to retreat, so that the discharging of the battery cell is finished.
In some embodiments of the present utility model, as shown in fig. 3 and 4, jacking cylinders are disposed on two sides of the teflon platform, and the connection line direction of the two jacking cylinders is perpendicular to the extension and retraction direction of the battery cell hand-changing support plate.
Specifically, the jacking cylinder comprises two groups of cylinders which are respectively arranged at two sides of the Teflon cloth platform, so that the stress at two sides of the Teflon cloth platform in the lifting process is balanced. Avoid the electric core weight to lead to the deviation of teflon cloth platform. The connecting line direction of the jacking cylinder is perpendicular to the telescopic direction of the battery cell hand-changing support plate, so that the telescopic path of the battery cell hand-changing support plate can be prevented from being blocked.
In some embodiments of the present utility model, as shown in fig. 1 and 2, the hot-pressing driving assembly is connected with each cell hot-pressing mechanism through a hydraulic column, when the hot-pressing push plate is driven to press down by the pressurizing cylinder, each cell hot-pressing mechanism synchronously presses down, and the upper hot-pressing plate presses down to hot-press the cells.
Specifically, in the process of pressing and heating the battery cell, the hydraulic column is gradually compressed by the battery cell hot-pressing mechanism, so that the upper hot-pressing plate approaches to the top surface of the battery cell. After the heating of the battery core is completed, the hydraulic column is lifted up after the pressure of the pressurizing cylinder is released, so that the upper hot-pressing plate is retracted and reset. The hydraulic column is a technical solution well known to those skilled in the art, and will not be described in detail in this embodiment.
In a further embodiment, as shown in fig. 1 and 2, a temperature controller 430 is included and electrically connected to each cell hot press mechanism for monitoring the cell hot press temperature within each cell hot press mechanism. Specifically, the number of the temperature controllers 430 capable of simultaneously monitoring the temperature is equal to the number of the hot-pressing mechanisms of the battery cells, and the number of the monitored temperatures of the temperature controllers 430 can be adjusted according to the hot-pressing mechanisms of the battery cells. The temperature controller 430 can employ any one of a thermal resistance sensor, a thermistor sensor, a thermocouple sensor, and an infrared temperature sensor.
In some embodiments of the present utility model, as shown in fig. 1 and 2, an upper hot-pressing plate of the cell hot-pressing mechanism below the hot-pressing plate is disposed at one side of the hot-pressing plate. Because the top of the electric core hot pressing mechanism at the uppermost layer is connected with the hot pressing push plate, the upper hot pressing plate of the electric core hot pressing mechanism at the uppermost layer is arranged on one side of the hot pressing push plate, and the hot pressing push plate can drive the upper hot pressing plate to be close to the electric core of the electric core hot pressing mechanism at the top layer to press and heat. The base of the upper-layer electric core hot-pressing mechanism is used for driving the upper hot-pressing plate of the lower-layer electric core hot-pressing mechanism to press the surface of the electric core.
In some embodiments of the present utility model, as shown in fig. 1 and 2, the device comprises a support base, which is disposed at one side of the base of the lowest-layer cell hot-pressing mechanism, and is used for supporting the cell hot-pressing mechanism and the hot-pressing driving assembly.
In some embodiments of the present utility model, as shown in fig. 3 and 4, a buffer cylinder is disposed at the bottom of the electric core hot pressing mechanism, and the buffer cylinder is disposed below the edge of the teflon platform and is used for supporting the frame of the teflon platform. The buffer cylinder is a technical solution well known to those skilled in the art, and will not be described in detail in this embodiment.
