A lithium battery pole piece mold forming die-casting system and die-casting process. The system includes a conveyor belt and a driving wheel. Several die-casting devices are fixedly installed on the conveyor belt. The die-casting device includes a lower mold and an upper mold that match each other. Fluid and slurry, the upper mold is used to extrude the slurry and current collector located in the lower mold; during the movement of the die-casting device along the conveyor belt, at least one die-casting cycle is completed, and in the die-casting cycle, the lower mold and the upper mold are heated up to After the drying temperature, the temperature starts to drop. During the cooling process, the upper mold continues to apply pressure to the slurry and the current collector until the lithium battery pole piece is formed. During the process of moving on the conveyor belt, the die-casting device of the present invention independently completes at least one die-casting cycle. In one die-casting cycle, the upper mold does not continuously apply pressure to the material in the lower mold, effectively preventing the current collector from being pressurized. The rebound occurs, which significantly improves the die-casting effect and quality of the die-casting process.

The application provides a substrate with a pixel structure, an optoelectronic device containing the same and a printing method. The pixel structure in the substrate with the pixel structure includes a pixel unit with sub-pixels, each sub-pixel includes a pixel isolation area and a light-emitting area, the light-emitting area is the area where the pixel isolation structure in the pixel isolation area and the depression surrounded by the substrate are located, and the depression It is used to contain the liquid material ejected by the inkjet printing device. The shape of the bottom surface of the depression is the first plane figure S1, the area of ​​1≤S2 / the area of ​​S1≤1.5, and S2 and S1 have an intersection, the intersection is S1, and S2 is The inkjet printing device prints the ejected liquid material once at a specific height from the test substrate, and forms a second plane figure after drying on the flat surface of the test substrate. The test substrate is a conductive substrate without a pixel isolation layer structure . The present application achieves the effect of improving the uniformity of the film layer in the light-emitting region and the uniformity of light emission of the light-emitting device.

The invention discloses a particle dispersing device based on an unmanned aerial vehicle. The particle dispersing device comprises an unmanned aerial vehicle, a storage box, a feeding mechanism and adispersing mechanism; a discharging hole is formed in the bottom of the storage box; the feeding mechanism is rotatably mounted in the storage box, and the power input end of the feeding mechanism ismovably connected with the dispersing mechanism by the discharging hole; the dispersing mechanism is arranged below the discharging hole to receive particulate matters falling from the discharging hole; a downward air flow of the unmanned aerial vehicle acts on the dispersing mechanism to drive the feeding mechanism and the dispersing mechanism to work; and the particulate matters are transportedto the discharging hole by the feeding mechanism. Airfoils of the unmanned aerial vehicle generate the downward air flow, the air flow acts on the dispersing mechanism to drive the dispersing mechanism and the feeding mechanism to work, and mounting a motor and a draught fan on the storage box to respectively drive the feeding mechanism and the dispersing mechanism to work is not needed, so that not only is the weight of the device reduced, but also consumption of electric energy of the unmanned aerial vehicle is reduced, and furthermore, the work efficiency is increased. The particle dispersing device has the beneficial effects of simple structure, artful design and strong cruising ability.

The invention relates to a support-free 3D printing method. The support-free 3D printing method at least includes the following steps that a light-sensitive material is unfolded to form a material film layer with the uniform thickness, the material film layer is exposed through a light source according to a slice pattern, and printing of a first layer of a 3D model is completed; the non-exposed part of the material film layer serves as the starting layer for printing of a second layer of the 3D model, and the second layer of the 3D model is printed according to the same printing method of thefirst layer; the non-exposed part of the material film layer during printing of the second layer serves as the starting layer for printing of a third layer of the 3D model, and the third layer of the3D model is printed according to the same printing method of the second layer; and the cycle is repeated in this way until the 3D model is printed. According to the 3D printing method, the gel state of the light-sensitive material is used as a support, addition of a support is not needed, printing difficulty is greatly lowered, and the success rate is improved. As no support is added, detachment of a support is not needed, and a printed part is more beautiful.
