The arrangement mode of the pressure head suspension of the pressure mechanism aims to shorten the working stroke of the pressure mechanism by matching with the switching column mechanism arranged below so as to improve the hot pressing efficiency. In other words, if this technical purpose is not to be achieved, the pressing mechanism can also take the form of structures commonly used in the art, such as: the power output end of the pressing mechanism is directly connected with the top pressing plate at the top of the multilayer press-fit molding assembly or directly connected with the bottom pressing plate at the bottom of the multilayer press-fit molding assembly.

The longitudinal linear reciprocating driving mechanism adopts a servo motor 1-1 as a preferred embodiment, and a driving member capable of providing vertical pressure, such as an air-liquid pressure cylinder, can also be used.

The multilayer press-fit molding assembly comprises more than two press plates; a plurality of clamp plates set gradually on pressfitting support 9, including the bottom clamp plate 8 that is located the below and the at least portable clamp plate that is located bottom clamp plate 8 top, when only there is a clamp plate in bottom clamp plate 8 top, the clamp plate of bottom clamp plate 8 top is top clamp plate 2 promptly, when the clamp plate of bottom clamp plate 8 top is more, the clamp plate that is located the top is top clamp plate 2, and the clamp plate that is located between top clamp plate 2 and bottom clamp plate 8 is middle clamp plate 5.

In order to make multilayer lamination equipment during operation, be located each layer treat that to press the work piece atress unanimous, the utility model discloses a following scheme: a jacking mechanism is arranged between every two adjacent pressing plates; one end (such as a fixed end) of the jacking mechanism is fixedly connected with the lower pressing plate, the other end (such as a power output end) of the jacking mechanism is fixedly connected with the upper pressing plate, the jacking mechanism can keep constant output force in the process of pressing and shaping the battery cell, and the constant output force is force required for balancing the gravity of all movable parts connected above the jacking mechanism. Under the arrangement, when the lamination device presses the cells, the jacking mechanism of each layer can balance the gravity of the movable mechanism connected with the jacking mechanism above the jacking mechanism, and the pressure applied to each layer of cells is the force given by the longitudinal linear reciprocating driving mechanism, namely the force detected by the pressure sensors 1-5.

Specifically, when the jacking mechanism is set as the cylinder 4, as shown in fig. 1, the cylinder 4 is fixed on the upper surface of the lower pressing plate, the piston rod of the cylinder is fixedly connected to the upper pressing plate, and in the equipment debugging stage, the electric proportional valve is calibrated, so that the piston rod of the cylinder can keep constant output force during being compressed (by controlling the electric proportional valve). The constant output force described above is the force required to balance the weight of all the associated movable mechanisms above the piston rod of the cylinder 4.

More specifically, in order to avoid the pressing position and make the stress of the whole device more balanced, it is preferable that two air cylinders are arranged between each two pressing plates, and the two air cylinders are arranged symmetrically in front and back (the coordinate is shown in fig. 1, and the direction perpendicular to the paper surface is the front and back direction).

The movable pressing plate is longitudinally (vertically in fig. 1) slidably supported on the pressing support 9 through a connecting plate 10, preferably, the connecting plate is arranged to be concave, as shown in fig. 2, the notch is downward, so that the manipulator and/or the battery cell can conveniently pass through the connecting plate when the material is loaded and unloaded, and the concave connecting plate enables the whole equipment to be lower and more compact compared with a rectangular connecting plate. But then the fine finishing lower surface and the leveling subassembly upper end butt of "concave" shape connecting plate for the depth of parallelism between the upper and lower clamp plate after adjusting obtains guaranteeing, and its principle lies in:

the influence of the pressing molding module is not considered, the parallelism requirement of the upper surface and the lower surface of the electric core after being pressed can be converted into the parallelism requirement between the current pressing plate and the adjacent upper pressing plate (to be exact, the parallelism between the upper surface of the current pressing plate and the lower surface of the adjacent upper pressing plate), the lower surface of the movable platen is fixedly supported on the upper surface of the connecting plate, and errors caused by finish machining are within the tolerance range of the movable platen (the upper surface and the lower surface of the platen and the upper surface and the lower surface of the concave-shaped connecting plate can be subjected to finish machining, but the concave part of the connecting plate is difficult to be subjected to finish machining), the parallelism requirement between the current pressing plate and the adjacent upper pressing plate is converted into the parallelism requirement between the lower surface (the protruded lower surface) of the concave connecting plate fixedly connected with the lower surface of the current pressing plate and the lower surface (the concave connecting plate) fixedly connected with the lower surface of the adjacent upper pressing plate.

In short, in order to improve the post-pressing quality of a workpiece to be pressed (such as a battery cell), the parallelism between the pressing plate and the pressing plate must be ensured.

In other words, the movable pressing plate adjacent to the bottom pressing plate and the supporting bottom plate of the pressing support are provided with the equal-height columns; one end of the equal-height column is fixed with the supporting bottom plate, and the other end of the equal-height column can be abutted against the movable pressing plate.
