Further, referring to fig. 7 and 8, the layer plate 400 is provided with a guide through hole 401 through which the corresponding first support guide shaft 310 passes, and a plurality of rolling supports 410 are provided in the guide through hole 401 and are tangential to the surface of the first support guide shaft 310. When the layer 400 moves along the first support guide shaft 310, the rolling support 410 rolls along the first support guide shaft 310. In this embodiment, since the rolling support 410 is in rolling connection with the first support guide shaft 310 passing through the guide through hole 401, the rolling contact replaces the original sliding contact, thereby reducing the friction force and further reducing the abrasion of the laminate 400 and the first support guide shaft 310; and the driving force for pressing the battery by the driving laminated plate is reduced, and the energy consumption is reduced. In the formation process, when the adjacent laminate 100 presses the battery, the friction is reduced, so that the pressure detected by the pressure sensor is close to the pressure applied to the battery, the formation pressure of the battery can be well controlled in the formation process of the battery, and the formation quality of the battery is improved.
Further, referring to fig. 8, an inwardly recessed cavity 402 is further disposed on a side surface of the laminate 400 along an outer edge of each of the guiding through holes 401, an inwardly recessed clearance gap 403 is further disposed on a bottom wall of the cavity 402 along an edge of the guiding through hole 401, and positioning grooves 404 are disposed at two ends of the clearance gap 403. The rolling support 410 comprises a support shaft 411 and a rolling bearing 412, the rolling bearing 412 is sleeved on the support shaft 411, two ends of the support shaft 411 are positioned in the positioning grooves 404, and one side of the rolling bearing 412 extends into the guide through hole 401; a cover plate 413 is further arranged in the cavity and used for pressing the supporting shaft 411 in the positioning groove 404, and the cover plate 413 is in screw connection with the layer plate 400; the bottom of the cover plate 413 is provided with a space avoiding position corresponding to the rolling bearing 412. In this embodiment, the support shaft 411 is positioned in the positioning groove 404 by fitting the rolling bearing 412 on the support shaft 411, and the support shaft 411 is press-fixed in the positioning groove 404 by the cover plate 413. It is further achieved that one side of the rolling bearing 412 extends into the guide through-hole 401, and thus when the first support guide shaft 310 passes through the guide through-hole 401, the rolling bearing 412 is in contact with the first support guide shaft 310, thereby achieving rolling support of the laminate 400 on the first support guide shaft 310. And the present structure can replace the rolling bearing 412 and the support shaft 411.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
