Problems solved by technology

However, during the winding process of the pole piece, it usually happens that the pole piece sags due to gravity at the winding position. If the pole piece sags slightly, the alignment between the pole piece and the separator will be unqualified, which will affect the battery cell. Yield rate and safety performance, if the pole piece droops seriously, it will cause the pole piece to fail to be rolled normally, which will affect the quality of the battery cell

[0034] Please refer to figure 1 (Hollow arrows in the figure indicate the direction of air flow), an embodiment of the present invention provides a cell winding system 10 for winding and producing cells. It can blow and guide the pole piece 500 to balance the gravity of the pole piece 500 and prevent the pole piece 500 from sagging, and the guided airflow can flow out smoothly without affecting the winding of the pole piece 500, which is practical and reliable.

[0035] It should be noted that the cell winding system 10 includes a diaphragm roller 200 , an air blowing guide device 100 and a winding needle 300 . The diaphragm roller 200 is used to limit the diaphragm 400, and sends the diaphragm 400 into the winding needle 300, and the blowing guide device 100 is used to blow and guide the pole piece 500 so that the pole piece 500 enters the winding needle 300, and the winding needle 300 is used to drive the diaphragm 400 and the pole piece 500 to rotate at the same time, so a...

[0048] Please refer to Figure 5 The embodiment of the present invention provides an air blowing guide device 100. Compared with the first embodiment, the difference of this embodiment is that the adjustment mode of the air blowing guide device 100 is electric drive.

[0049] In this embodiment, the air blowing guide device 100 further includes a first driving mechanism 180 and a second driving mechanism 190 . The first driving mechanism 180 is installed on the fixing plate 140 and is connected with the connecting shaft 150. The first driving mechanism 180 is used to drive the mounting table 160 away from or close to the fixing plate 140 through the connecting shaft 150, thereby driving the substrate 120 away from or approaching the fixing plate. 140 , that is to realize the function of translation of the substrate 120 along the axial direction of the connecting shaft 150 . The second driving mechanism 190 is installed on the connecting shaft 150 and connected to the mounting...

Abstract

The invention discloses a blowing guide device and a battery cell winding system, and relates to the technical field of battery cell production. The blowing guide device comprises an air blowing mechanism, a base plate and a guide piece, wherein the base plate is provided with an air outlet hole, the air blowing mechanism is fixedly installed on the base plate and communicated with the air outlethole, the guide piece is fixedly connected with the base plate and extends in the direction close to the air blowing mechanism, the air blowing mechanism is used for blowing out air flow through the air outlet hole to guide a pole piece, and the guide piece is used for guiding the air flow. Compared with the prior art, the blowing guide device provided by the invention can blow and guide the polepiece to balance the gravity of the pole piece and prevent the pole piece from drooping due to the adoption of the air outlet mechanism communicated with the air outlet hole and the guide piece connected to the base plate, and the guided air flow can stably flow out without influencing the coiling of the pole piece.

Description

technical field [0001] The invention relates to the technical field of electric core production, in particular to an air blowing guide device and an electric core winding system. Background technique [0002] At present, in the process of producing lithium battery cells by winding on the winding machine, it is necessary to wind the pole piece and the separator outside the winding needle at the same time to ensure the alignment of the pole piece and the separator. However, during the winding process of the pole piece, it usually happens that the pole piece sags due to gravity at the winding position. If the pole piece sags slightly, it will cause the alignment of the pole piece and the separator to be unqualified, which will affect the cell. The yield rate and safety performance, if the pole piece sags seriously, it will cause the pole piece to be unable to be rolled normally, which will affect the quality of the battery cell. [0003] In view of this, it is particularly imp...
