Description

Technical Field

[0001] The invention belongs to the technical field of ceramic photocuring additive manufacturing and particularly relates to a multi-layer composite ceramic surface exposure molding device and a molding method thereof. Background Art

[0002] Compared with metal materials and polymer materials, ceramic materials have excellent physical properties such as wear resistance, acid and alkali resistance, and high temperature stability. They are widely used in the fields of industry and manufacturing and have great value. With the development of technology, single-phase ceramic materials are difficult to meet the complex requirements in actual production. In actual use, multiple ceramic materials are often used in combination to give full play to the advantages of multiple materials, thereby improving the performance of the materials.

[0003] Multilayer ceramics are a type of composite ceramics. Two ceramic materials are stacked in a two-dimensional orientation to form a multilayer material. Multilayer ceramics usually complement each other with ceramics with different characteristics to improve the performance of a single material, such as increasing strength, increasing toughness, and improving dielectric properties, and ultimately obtaining good comprehensive performance. Taking the multilayer ceramic zirconia composite alumina as an example, zirconia ceramics have a high density, high strength and toughness, but poor insulation properties and high cost, while alumina ceramics have a low density, strong insulation properties, and high hardness. Zirconia composite alumina is used to prepare dual-phase ceramics, which fully utilizes the insulation properties and low density of alumina and the high strength and thermal shock resistance of zirconia, greatly broadening the application scenarios.

[0004] There are many traditional methods for making multilayer composite ceramics, such as rolling film forming, tape casting, slip casting, screen printing, stereolithography, etc. However, these methods still have certain limitations in application. The rolling film forming method takes a long time to make and has poor precision; the tape casting method takes a long time to make and it is difficult to control the shape of multiphase materials; the slip casting method has a long production cycle and low efficiency, and the formed ceramics are easily deformed after sintering; the screen printing method has high production costs, is not suitable for small batch production, has limited precision, and has low production efficiency; the stereolithography method has high technical precision and high efficiency, but its ink direct writing usually uses extrusion to move along the path, and solidifies immediately while extruding to maintain the shape, which is inefficient. Therefore, it is necessary to develop a multilayer ceramic forming device and forming method with a short material preparation cycle, high efficiency, and good forming effect.

[0033] Combine the following Figure 1 Embodiments of the present invention are described.

[0034] The present embodiment relates to a multi-layer composite ceramic surface exposure molding device and a molding method thereof. The traditional multi-layer ceramic molding method has certain limitations, and its material preparation cycle is long, the efficiency is low, and the molding effect is poor.

[0035] An embodiment of the present invention provides a multilayer composite ceramic surface exposure molding device, including a molding platform 1, a lifting mechanism, a first feeding mechanism, a second feeding mechanism, a first nozzle 21, a second nozzle 22, an ultraviolet light source 3, a moving mechanism and a control mechanism (not shown in the figure), wherein the molding platform 1 is mounted on the lifting mechanism, and the lifting mechanism is used to drive the molding platform 1 to move up and down; the first nozzle 21 is connected to the first feeding mechanism, and the second nozzle 22 is connected to the second feeding mechanism; the moving mechanism is arranged above the molding platform 1, and the first nozzle 21, the second nozzle 22 and the ultraviolet light source 3 are respectively fixedly installed on the moving mechanism, and the first nozzle 21, the second nozzle 22 and the ultraviolet light source 3 are respectively facing the molding platform 1, and the moving mechanism drives the first nozzle 21, the second nozzle 22 and the ultraviolet light source 3 to switch positions; the control mechanism is used to control the feeding of the first feeding mechanism and the second feeding mechanism, and control the movement of the moving mechanism.

[0036] In this embodiment, through the independent setting of dual nozzles (first nozzle 21 and second nozzle 22) and dual feeding mechanisms (first feeding mechanism and second feeding mechanism), two ceramic slurries of different components (first slurry and second slurry) are respectively fed into the first feeding mechanism and the second feeding mechanism, thereby realizing independent spraying of the two ceramic slurries of different components. In addition, by setting up the moving mechanism, the first nozzle 21 or the second nozzle 22 can be flexibly switched for spraying according to the design requirements of the interlayer structure of the ceramic material, and the ultraviolet light source 3 can be switched for irradiation and curing, so as to obtain a multilayer composite ceramic with a complex structure and composition.

[0037] Furthermore, in this embodiment, the spraying range of the first nozzle 21 and the second nozzle 22 is set to a diameter of 20 cm, the distance between the first nozzle 21 and the second nozzle 22 and the forming platform 1 is equal, set to 30 cm, and the spraying pressure of the first nozzle 21 and the second nozzle 22 is less than 1 bar to prevent the ceramic slurry from splashing during the spraying process and affecting the printing effect.

[0038] Furthermore, the moving mechanism includes a turntable 41, which is movably installed above the molding platform 1. The first nozzle 21, the second nozzle 22 and the ultraviolet light source 3 are respectively fixedly installed on the turntable 41 and arranged in a circular array along the turntable 41. The turntable 41 is transmission-connected to the control mechanism. This embodiment can ensure that the spraying of the first nozzle 21 or the second nozzle 22 and the irradiation of the ultraviolet light source 3 are in the same area after switching through rotary position switching.

[0039] Furthermore, the moving mechanism also includes a rotating shaft 42 and a first motor 43. The turntable 41 is transmission-connected to the first motor 43 via the rotating shaft 42. The first motor 43 is electrically connected to the control mechanism. The control mechanism of this embodiment can control the first motor 43 to drive the turntable to rotate to switch the working parts according to the working conditions. For example, if the first slurry needs to be sprayed according to the designed multi-layer ceramic model, the control mechanism controls the turntable 41 to rotate so that the position of the first nozzle 21 is switched to a preset working area above the molding platform 1. After the first nozzle 21 completes the spraying of the first slurry to form a single-layer ceramic layer, the control mechanism controls the turntable 41 to rotate so that the ultraviolet light source 3 is switched to irradiate the working area to complete single-layer printing. The same is true when the second nozzle 22 is working.

The encoder is used to capture the position information of the turntable 41, and the control mechanism controls the position of the turntable 41 according to the position information. This embodiment accurately captures the position information of the turntable 41 through the setting of the encoder, thereby ensuring the accuracy of the position switching of the working part, so that the spraying area of ​​the first nozzle 21 or the second nozzle 22 is the same as the irradiation area of ​​the ultraviolet light source 3.

In this embodiment, according to the spraying time parameters designed for the multilayer ceramic model and the viscosity parameters of the prepared ceramic slurry, the extraction rate of the first feed pump 53 (or the second feed pump 56) is controlled by the control mechanism, and the first slurry (or the second slurry) is extracted from the first slurry tank 51 (or the second slurry tank 54), and the first slurry (or the second slurry) is transported to the first nozzle 21 (or the second nozzle 22) through the first delivery pipe 52 (or the second delivery pipe 55) for spraying, thereby controlling the spraying thickness of the single ceramic layer.

[0042] Furthermore, the lifting mechanism includes a lifting base 61, a guide rail 62, a slider 63, and a second motor (not shown in the figure). The forming platform 1 is mounted on the slider 63. The guide rail 62 is fixedly mounted on the lifting base 61. A rack (not shown in the figure) is provided on the guide rail 62. The second motor is fixedly mounted on the slider 63. A gear (not shown in the figure) is provided on the slider 63. The gear is connected to the second motor through a transmission shaft. The gear is meshed with the rack. The second motor is electrically connected to the control mechanism.
