DETAILED DESCRIPTION

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0019] like Figure 1-8 As shown, an additive manufacturing device for hydrogen energy electrode production includes: a device body 1 and a molding platform 2 on the device body 1, a side stage 3 arranged on one side of the device body 1, a slow-dissipation mechanism 4 arranged on the bottom surface of the molding platform 2 and the device body 1, a sintering treatment component 5 installed on the side stage 3 and the device body 1, and an impregnation treatment component 6 arranged on the side stage 3 and not located behind the sintering treatment component 5; The sintering processing component 5 is close to the molding platform 2, and the device body 1 includes a printing head, etc., which prints layer by layer on the molding platform 2 until the required electrode is produced, wherein: The slow cooling mechanism 4 is suitable for directly transferring temperature to the molding platform 2 and above it during production, so as to control the temperature around the molding platform 2 to change gradually and smoothly; Driving the sintering treatment component 5 can automatically deliver the finished electrode into the heat treatment space so that the finished electrode can undergo subsequent sintering treatment; The impregnation treatment component 6 is suitable for continuous flow active impregnation of the finished electrode. The additive manufacturing device for hydrogen energy electrode production can actively generate heat around the electrode during the process of printing and producing the electrode by the device body 1 through the slow dissipation mechanism 4, so that the electrode is in the heat brought by the specific heat source during the entire production process, and the intensity of the heat can be gradually reduced or strengthened as the production work progresses or the actual situation, thereby ensuring that the temperature accompanying it changes gradually and smoothly during the manufacturing process of the electrode, thereby effectively avoiding excessive stress that causes deformation or cracks in the produced electrode. The finished electrode can be automatically removed from the forming platform after the electrode is completely produced through the sintering treatment component 5. 2 is received into its own heat treatment space, and the electrode can be subjected to subsequent sintering treatment. The impregnation treatment component 6 can provide an impregnation place for the electrode next to the sintering treatment component 5, so that the electrode can be impregnated immediately after the sintering treatment. At the same time, the impregnation treatment component 6 can make the impregnation solution circulate continuously around the electrode, thereby strengthening the contact and exchange between the impregnation solution and the electrode, thereby improving the impregnation effect and efficiency. The additive manufacturing device for hydrogen energy electrode production can effectively ensure the stability of production quality, and concentrate the required subsequent processing steps together, greatly improving the process integration of the entire production process, effectively avoiding cumbersome steps to greatly improve production efficiency.

[0020] Optionally, the slow-dissipation mechanism 4 includes a heat transfer panel 41 integrally mounted on the bottom surface of the molding platform 2, a first electric heating wire 42 mounted on the heat transfer panel 41 in a continuously rotating shape, and the first electric heating wire 42 is connected to an external power supply, a hollow long rectangular block 43 arranged on the rear side of the molding platform 2, an external blowing port 44 connected to the hollow long rectangular block 43, a cold and warm air blower 45 mounted on the device body 1, and a hose 46 connected to the air outlet of the cold and warm air blower 45 at one end and connected to the hollow long rectangular block 43 at the other end; The external blowing port 44 faces the molding platform 2 and is located above the molding platform 2. When the device body 1 starts to print and produce electrodes, the external power supply is turned on to energize the first heating wire 42, so that it starts to heat up, and the heat is directly transferred to the heat transfer panel 41, and the heat is indirectly transferred to the molding platform 2 through the heat transfer panel 41, so that the temperature of the molding platform 2 is increased, and at the same time, the cold and warm air blower 45 is started to blow the warm air along the hose 46 into the hollow long rectangular block 43, and finally the warm air is blown out toward the electrode being printed through the external blowing port 44, so that under the cooperation of the two , so that the electrode is surrounded by actively generated heat throughout the entire printing process. As the printing progresses and the actual situation occurs, the temperature of the first heating wire 42 is controlled by controlling the current of the external power supply, and the temperature of the cooling and heating fan 45 is controlled accordingly, thereby ensuring that the temperature around the electrode can be flexibly and accurately controlled, and then the temperature of the electrode is passively regulated by the ambient air temperature, and the temperature of the electrode is controlled to rise or fall gradually and smoothly to prevent a sudden and drastic change in temperature from causing excessive stress and causing deformation or cracking of the electrode, thereby ensuring the stability of the electrode production quality.

[0021] Optionally, the slow-dissipation mechanism 4 further includes two groove back plates 47 vertically mounted on the device body 1 and respectively located on both sides of the rear of the hollow long rectangular block 43, two connecting pieces 48 respectively slidably mounted in the two groove back plates 47, and both of the two connecting pieces 48 are connected to the hollow long rectangular block 43, two pulling pieces 49 respectively mounted on both ends of the hollow long rectangular block 43 and respectively connected to the two connecting pieces 48 as one body, and two synchronous connecting ropes 491 one end of which is respectively connected to the two pulling pieces 49; The other ends of the two synchronous cables 491 are connected to the lifting component of the device body 1. The lifting component of the device body 1 rises layer by layer during printing production to ensure that the electrodes are printed layer by layer on the molding platform 2. During printing, every time the lifting component rises a little, the two synchronous cables 491 and the two pullers 49 pull the hollow long rectangular block 43 and the two connecting parts 48 upward synchronously, thereby ensuring that the height of the outer blowing port 44 can always match the printing progress, ensuring that the newly printed electrode layer can be surrounded by the cold and warm airflows produced by the cold and warm air blowers 45, so as to prevent the electrode height from gradually rising as the printing progresses. The high temperature causes the newly printed part to be unable to be affected by the slow-dissipation mechanism 4. The two connecting parts 48 rely on the two grooved back plates 47 to limit the hollow long rectangular block 43 to prevent its shaking and swinging, which may affect the effect of the slow-dissipation mechanism 4. The hose 46 is naturally curled under normal conditions to ensure that there is enough margin for the hollow long rectangular block 43 to gradually rise. Every time the lifting component rises a little, the upper electrode layer has slowly reduced its own temperature to an appropriate value under the protection of the heating and cooling fan 45, and the first heating wire 42 continues to protectively adjust the electrode temperature in the subsequent process to avoid large and sudden changes in the electrode temperature.

After the printing production of the electrode is completed, the finished electrode is placed on the first grid tray 56, and then the cover 53 is closed so that the electrode is in a closed environment composed of the rectangular heat transfer dish 51 and the cover 53. Then, the second heating wire 52 and the third heating wire 54 are energized and the current is controlled to an appropriate value required for the sintering treatment. The heat generated by the second heating wire 52 and the third heating wire 54 is used to continuously heat treat the electrode until the sintering is completed, ensuring that the electrode can be immediately transferred to the subsequent sintering treatment after it is produced.
