[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0018] Embodiment

[0019] As Figure 1 shown, Figure 1 Shown is an overall schematic diagram (top view) of the oil removal device in the embodiment;

[0020] The continuous casting and rolling process flow of the grid 1 includes: unwinding - diversion - coating, and the corresponding devices used are as follows: unwind device 11 - diversion device 12 - coater,

[0021] The diversion device 12 includes a roller 13, and the grid 1 is diverted and conveyed on the roller 13;

[0022] The oil removal step is set at the end of the diversion and before coating. The grease on the surface of the grid 1 is removed before coating the grid 1 to improve the bonding force between the grid 1 and the active material, improve the performance of the punched grid battery, and ensure the service life of the battery.

[0023] As Figure 1 , Figure 2 shown, Figure 1 Shown is an overall schematic diagram (top view) of the oil removal device in the embodiment; Figure 2 Shown is a schematic diagram of the state cooperation between the diversion device and the oil removal device in the embodiment;

[0024] The oil removal device 20 includes:

[0025] A fire row burner 21, which is arranged at one end of the diversion device 12 away from the unwind device 11, and the fire row burner 21 includes a generated flame 22;

[0026] When the grid 1 is conveyed on the roller 13 through the position above the fire row burner 21, the heat generated by the flame 22 of the fire row burner 21 removes the grease adhering to the surface of the grid 1.

[0027] Specifically, the fire row burner 21 is provided with combustion ports. In this embodiment, the arrangement form of the combustion ports is four rows and twenty columns, and flames 22 are generated in multiple combustion ports; the height of the effective flame 22 heat generated by the fire row burner 21 is 15 cm, the space height between the grid 1 and the fire row burner 21 is 12 cm, and the surface temperature of the grid 1 passing directly above the flame 22 > 300 °C, so as to achieve the removal of grease.

[0028] The oil removal device 20 provided at the end of the diversion device 12 enables the grease on the surface of the grid 1 to be removed before the coating step of the grid 1.

[0029] As Figure 2 shown, Figure 2 It shows a schematic diagram of the state cooperation of the diversion device and the oil removal device in the embodiment;

[0030] The installation angle of the fire row burner 21 is the same as the angle when the grid 1 passes directly above the fire row burner 21;

[0031] The conveying form of the grid 1 at the end of the diversion device 12 is in a slightly inclined state. To ensure the uniformity of oil removal from the grid 1, the fire row burner 21 is also set in an inclined state, with the same inclination angle as the grid 1. In this embodiment, the inclination angle is about 15-20°.

[0032] As Figure 1 shown, Figure 1 It shows a schematic diagram of the overall oil removal device in the embodiment (top view perspective);

[0033] It also includes a gas input source 23. The gas input source 23 transports gas to the fire row burner 21 through a gas pipeline to generate a flame 22, and a solenoid valve 27 is provided on the gas pipeline;

[0034] Specifically, it also includes a controller electrically connected to both the fire row burner 21 and the solenoid valve 27;

[0035] The solenoid valve 27 is connected to the igniter of the fire row burner 21. The solenoid valve 27 controls the opening and closing of the igniter and controls the ignition time according to the actual production speed (the transmission speed of the grid 1) to ensure the best oil removal effect;

[0036] Specifically, when coating the plate, the moving speed of the grid 1 is 18 ± 2 m / min. During the forward movement of the grid 1, due to the buffering of the roller 13, the forward movement of the grid 1 at the end of the diversion device 12 will lag by about 2 - 3 seconds. Therefore, the ignition of the igniter is also delayed by 2 - 3 seconds through the solenoid valve 27, avoiding the melting of the grid 1 by the flame 22 due to the lag of the grid 1 movement.

[0037] A gas switch 25 and a pressure reducing valve 26 are also provided on the gas pipeline;

[0038] The gas switch 25 can quickly close the gas in the non - production state or emergency state. The pressure reducing valve 26 reduces the pipeline gas pressure from 4 KPa to 1 KPa which meets natural combustion to ensure the best working state of the gas burner 21.

[0039] Working principle: When the grid 1 is conveyed on the roller 13 of the diversion device 12 through the position above the gas burner 21, the gas burner 21 generates a flame 22, and the flame 22 and the heat generated remove the grease attached to the surface of the grid 1.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
