The utility model discloses a prime coat device for corner window glass processing, which comprises a bottom plate, the top of the bottom plate is fixedly connected with a driving box through a support, and the inside of the driving box is rotatably connected with a threaded rod. The movable frame capable of moving back and forth is arranged at the top of the bottom plate, and the first motor is matched to drive the threaded rod to rotate, so that the front-back accurate movement of the supporting plate and the clamping assembly is realized. And by adjusting the position of the movable frame, it can be ensured that the spraying head and the glass edge keep the optimal spraying distance, and the problem that the coating thickness is not uniform due to inconsistent operation methods during traditional manual coating is effectively solved. Meanwhile, a first electric cylinder and a sliding column structure are arranged on the right side of the movable frame, the mounting frame is allowed to be finely adjusted in the left-right direction, the adaptability of the device to corner window glass in a complex shape is further improved, the distance between a spray head and the corner window glass is adjusted, and the overall prime coat quality is improved. The device has the advantage of being good in spraying effect.

The present disclosure provides a safe conductive coating slurry, a composite current collector and a preparation method thereof, and a battery, and belongs to the field of battery materials. The safe conductive coating slurry for the composite current collector comprises, in terms of mass fraction, 15-30 parts of a main material, the main material comprising microcrystalline glass; 10-30 parts of a binder; 10-20 parts of a solvent; 0.5-2 parts of a dispersing agent; 0.5-1 part of a wetting agent; and 0.5-1 part of a leveling agent. The coating slurry of the present disclosure comprises microcrystalline glass, which can simultaneously play the roles of a conductive coating and a safe coating by only coating one layer of coating, thereby simplifying the preparation process and the coating process; when combined with an electrode active material, the coating slurry does not cause the electrode active material to fall off; and the safe conductive coating has no cracking phenomenon. The technical problems of the prior art, such as the complexity of the slurry preparation process and the coating process when the two-layer structure of the conductive coating and the safe coating is coated on the composite current collector, the easy falling off of the electrode active material when combined with the electrode active material, and the easy cracking of the conductive coating, are avoided.
