Abstract

The invention discloses a coating device, which comprises a coating die head, a coating die head, a coating die head, a coating die head and a coating die head, the coating die head is internally provided with a slit, and the slit can lead out slurry and enable the slurry to be coated on a base material; the detection module is used for detecting the thickness of the slurry coated on the base material; the piezoelectric adjusting module is arranged on the coating die head, and the piezoelectric adjusting module can be deformed so as to adjust the width of an outlet of the slit; and the feedback module is connected with the detection module and the piezoelectric adjustment module, and the feedback module controls the piezoelectric adjustment module to generate deformation according to the thickness detected by the detection module. According to the coating device, the thickness of the slurry in the width direction of the base material can be monitored and adjusted in real time, and it is guaranteed that the thickness of the slurry coated on the base material is consistent.

Description

technical field [0001] The present application relates to the technical field of battery manufacturing, and more particularly, to a coating device. Background technique [0002] The existing coating die head mainly uses bolts to adjust the slit width, and the adjustment process is cumbersome and the timeliness is poor. When the coating thickness is inconsistent in the width direction of the substrate, it is difficult to quickly adjust the slit width through bolts, resulting in poor coating thickness consistency. SUMMARY OF THE INVENTION [0003] An object of the present application is to provide a new technology solution for a coating device, which can solve the problem of poor consistency of coating thickness of the coating die in the prior art. [0004] According to a first aspect of the present application, a coating device is provided, comprising: a coating die head, wherein a slit is provided in the coating die head, and the slit can lead out the slurry and coat the ...
