Description

Technical Field

[0001] The utility model relates to the technical field of battery slice production, and more specifically to a water vapor drying device for slicing and dividing a battery slice. Background Art

[0002] During the battery production process, before carrying out processes such as stacking and string welding, it is often necessary to divide large-sized battery cells into small-sized battery cell slices.

[0003] At present, laser scribing is generally used to divide the battery cells. The general process of laser scribing is: the slotting laser first forms a cutting groove on the surface of the battery cell, the heating laser then heats the battery cell along the extension direction of the cutting groove, and the cooling mechanism finally sprays the coolant along the cutting groove on the battery cell, so that the battery cell is cracked along the cutting groove after being cooled, thereby obtaining two battery cell slices.

[0004] Before the battery slices are transported to the downstream processing station, the coolant remaining on the dicing side of the battery slices (i.e., the side formed along the dicing groove during the dicing process) needs to be dried. The existing drying method is high-temperature drying. Currently, this drying method has the following defects:

[0005] 1. High temperature drying takes a long time and will increase production costs;

[0006] 2. Excessively high temperatures may cause thermal damage to the battery cells.

[0007] Therefore, it is an urgent problem for technical personnel in this field to develop a water vapor drying device that can quickly dry the battery cells without causing damage to the battery cells. Utility Model Content

[0008] In view of this, the utility model provides a water vapor drying device for slicing and dividing battery cells, which can dry the cells quickly without causing damage to the battery cells.

[0009] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] A water vapor drying device for cell dicing and slicing, comprising:

[0011] A box body, the box body is arranged above the battery cell conveyor belt; the bottom ends of two opposite side walls of the box body are provided with notches for the battery cell conveyor belt to pass through;

[0012] A heating lamp tube, wherein a plurality of heating lamp tubes are provided and arranged at the top end of the interior of the box body;

[0013] An airflow pipeline, the airflow pipeline is connected to the top of the box and is filled with heated air; one end of the airflow pipeline extends out of the box and is connected to the air pump, and the other end is placed inside the box and is connected to an exhaust hose;

[0014] An air nozzle is connected to the end of the exhaust hose.

[0015] The beneficial effect of adopting the above technical solution is that in the utility model, the battery cells are transported to the box of the drying device by the conveyor belt, and the surface of the battery cells is dried by the heating lamp; while drying, hot air is introduced into the battery cells through the air flow pipeline, which can speed up the drying speed of the battery cells, and the drying temperature will not be too high, so as not to cause damage to the battery cells.

[0016] Preferably, the air nozzle is connected to a movable frame, and the movable frame is connected to the top of the box body. The setting of the movable frame can limit the position of the air nozzle to prevent the exhaust hose from shaking during the air jet process.

[0017] Preferably, threaded rods are provided at the four corners of the mobile frame, and the tops of the threaded rods pass through the top of the box body and are threadedly connected with the adjusting nuts. By adjusting the position of the adjusting nuts on the threaded rods, the mobile frame can be adjusted up and down, so that the height of the air nozzle can be adjusted appropriately according to needs.

[0018] Preferably, the movable rack is in a grid shape. The grid-shaped movable rack can reduce the shielding of the battery cells, so that the heating lamp tubes can better dry the battery cells.

[0019] Preferably, the air flow pipeline is located at one end of the box body and is connected to an air circuit connector, and the air circuit connector is connected to a plurality of exhaust hoses.

[0020] Preferably, the plurality of air nozzles are rotatably connected to the mobile frame, and the air jet ends of the air nozzles are directed toward the middle cutting groove of the battery sheet, so as to better dry the moisture in the middle cutting groove of the battery sheet.

[0021] Preferably, a heat preservation plate is arranged on the inner side wall of the box body, and the arrangement of the heat preservation plate can prevent the heat in the box body from being conducted out through the side wall of the box body.

[0022] Preferably, a heating box is provided on the top of the exterior of the box body, and one end of the airflow pipeline connected to the air pump passes through the heating box and is connected to the air pump.

[0023] Preferably, a heating rod is provided in the heating box, and the top of the heating rod is connected to the heating box; the airflow pipeline is spirally wound around the outside of the heating rod. The heating rod can heat the gas in the airflow pipeline, and the battery cell can be dried by the heated gas, which can speed up the drying of the battery cell.

[0024] It can be seen from the above technical solution that, compared with the prior art, the utility model discloses a water vapor drying device for cell dicing and slicing, which has the following beneficial effects:

[0025] (1) In the present invention, the battery cells are heated by heating lamps and by introducing heated air, which can increase the drying speed of the battery cells. The drying temperature will not be too high, which will not damage the battery cells and can save costs.

[0026] The air nozzle is directed toward the cutting groove of the battery cell, so that the cut side edges formed after the battery cell is split along the cutting groove can be dried, thereby improving the drying effect. BRIEF DESCRIPTION OF THE DRAWINGS
