Coating die, coating apparatus, and battery production apparatus

A coating die, comprising:

• a die body, wherein an accommodating cavity for accommodating a slurry is provided in the die body, and the die body is further provided with a coating gap communicating with the accommodating cavity and extending along a first direction;
• and
• a regulation assembly, wherein the regulation assembly comprises:
• a flow regulation member running through the die body along a second direction and running into the coating gap, the flow regulation member being configured to move along the second direction relative to the die body;
• and
• a drive mechanism and a transmission member, wherein the drive mechanism is connected to an end of the flow regulation member extending out of the die body so as to drive the flow regulation member to move along the second direction, and wherein the drive mechanism is connected to the end of the flow regulation member extending out of the die body via the transmission member so as to drive, via the transmission member, the flow regulation member to move a preset distance along the second direction per unit time;
• and
• the drive mechanism being configured to regulate displacement of the flow regulation member in the second direction according to coating weight information of a slurry flowing out of the coating gap;
• wherein the first direction and the second direction intersect with each other;
• wherein the transmission member moves along the first direction under a driving force of the drive mechanism and drives the flow regulation member to move along the second direction;
• and
• wherein in a same time period, a displacement of the transmission member in the first direction is larger than a displacement of the flow regulation member in the second direction;
• wherein the transmission member has a first inclined surface at an angle to both the first direction and the second direction, and the flow regulation member has a second inclined surface parallel to the first inclined surface;
• and
• the first inclined surface fits with the second inclined surface to convert linear motion of the transmission member in the first direction into linear motion of the flow regulation member in the second direction;
• wherein the transmission member comprises a first portion connected to the drive mechanism and extending along the first direction and a second portion connected to a side of the first portion away from the drive mechanism;
• and
• the first inclined surface is provided on the second portion;
• wherein the flow regulation member has a through groove for the second portion to run through, and the second inclined surface is provided on a side wall of the through groove.
