Description

Technical Field

[0001] This utility model relates to the technical field of aluminum foil production equipment, and in particular to a device for drying and forming a substrate surface slurry in the production of sintered foil. Background Technology

[0002] Sintering is a method used to produce aluminum foil. The raw materials for sintering are generally divided into solid powder and liquid slurry. The two raw materials are treated differently before sintering. Liquid slurry has fluidity, so it is usually filled with a template and then sent into the sintering furnace for sintering. Although the template can restrict the flow of the slurry and make it form, it is still easy to have large forming errors, which affects the pass rate of sintered products. Utility Model Content

[0003] The purpose of this invention is to provide a substrate surface slurry drying and molding device for sintered foil production. This device uses a mold to uniformly fill the slurry into the template, and then heats the slurry to make it initially formed and have a certain strength. When it is sent into the sintering furnace, there will be no significant structural changes, thus improving the pass rate of product sintering.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a substrate surface slurry drying and molding device for sintered foil production, comprising a worktable, an annular conveyor belt inside the worktable, an annular through hole matching the annular conveyor belt on the worktable, several trays evenly arranged above the annular conveyor belt, a template placed on the top of the tray, and a support rod arranged at the bottom of the tray, the support rod passing through the annular through hole and fixedly connected to the annular conveyor belt; a feeding robot, a feeding mechanism, an extrusion molding mechanism, and a discharging robot are arranged sequentially around the worktable, the feeding robot and the discharging robot are respectively arranged at both ends of the worktable, a feeding box is arranged below the feeding robot, and a discharging box is arranged below the discharging robot; the feeding mechanism includes a mounting frame, a feeding box is arranged on the mounting frame, and a feeding port matching the template is arranged at the bottom of the feeding box; the extrusion molding mechanism includes a lifting frame, a lifting plate is arranged below the lifting frame, a lifting cylinder is arranged between the lifting plate and the lifting frame, a pressing mold matching the template is arranged at the bottom of the lifting plate, and an electric heating tube is arranged inside the pressing mold.

[0005] Optionally, a mounting plate is provided below the mounting frame, an adjusting cylinder is provided between the mounting plate and the mounting frame, a feeding box is provided on the top of the mounting plate, and a feeding port is provided at the bottom of the mounting plate through the mounting plate.

[0006] Optionally, a baffle is installed at the feeding port, and several outlets are evenly distributed on the baffle.

[0007] Optionally, the tray is provided with several limiting grooves evenly spaced, and the template is placed in the limiting grooves.

[0008] Optionally, the size of the limiting groove is slightly larger than the size of the template, and the top of the template is provided with a trumpet-shaped guide opening.

[0009] The substrate surface slurry drying and molding device of this invention for sintered foil production has the following advantages:

[0010] (1) The circular conveyor belt operates intermittently, with a consistent conveying distance for each run, ensuring that there are trays below the loading robot, feeding mechanism, extrusion molding mechanism, and unloading robot. The loading robot can place empty templates into the trays, then the feeding mechanism adds slurry into the templates, the extrusion molding mechanism performs preliminary drying and molding of the slurry in the templates, and finally the unloading robot removes the templates, and the empty trays are rotated back to the loading robot to complete the cycle.

[0011] (2) The adjustable cylinder can adjust the distance between the feeding port and the template. When adding slurry, the distance between the feeding port and the template should be closer to avoid slurry splashing.

[0012] (3) The limiting groove can restrict the movement of the template and improve the accuracy of material feeding and extrusion molding. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figures 1-5 As shown, a substrate surface slurry drying and molding device for sintered foil production includes a workbench 1, an annular conveyor belt inside the workbench 1, an annular through hole 2 matching the annular conveyor belt on the workbench 1, several trays 3 evenly arranged above the annular conveyor belt, several limiting grooves 4 evenly arranged on the trays 3, templates 5 placed in the limiting grooves 4, the size of the limiting grooves 4 being slightly larger than the size of the templates 5, a support rod provided at the bottom of the trays 3, the support rod passing through the annular through hole 2 and fixedly connected to the annular conveyor belt, the annular conveyor belt being able to drive the trays 3 to rotate.

[0020] Around the workbench 1, a loading robot 6, a feeding mechanism 7, an extrusion molding mechanism 8, and a unloading robot 9 are arranged in sequence. The loading robot 6 and the unloading robot 9 are respectively located at both ends of the workbench 1. A loading box 10 is located below the loading robot 6. The loading robot 6 takes out an empty template 5 from the loading box 10 and places it on the tray 3. A unloading box 11 is located below the unloading robot 9. The unloading robot 9 takes the molded template 5 from the tray 3 and puts it into the unloading box 11. The feeding mechanism 7 includes a mounting frame 12, a mounting plate 13 is provided below the mounting frame 12, an adjusting cylinder 14 is provided between the mounting plate 13 and the mounting frame 12, a feeding box 15 is provided at the top of the mounting plate 13, and a feeding port 16 is provided at the bottom of the feeding box 15. The feeding port 16 passes through the mounting plate 13 and is located at the bottom of the mounting plate 13. A baffle 17 is installed at the feeding port 16, and several outlets 18 are evenly opened on the baffle 17. The outlets 18 enable the feeding port 16 to evenly add slurry into the template 5, avoiding slurry accumulation, which would affect the molding accuracy. The molding process of the slurry is continuous and stable. The initially molded slurry has a certain strength and will not easily deform, thereby ensuring the sintering quality and improving the product qualification rate.

[0021] The extrusion molding mechanism 8 includes a lifting frame 19, a lifting plate 20 below the lifting frame 19, a lifting cylinder 21 between the lifting plate 20 and the lifting frame 19, and a pressure mold 22 matching the number of templates 5 at the bottom of the lifting plate 20. An electric heating tube is installed inside the pressure mold 22. The pressure mold 22 is located directly above the templates 5, and a trumpet-shaped guide opening 23 is provided at the top of the templates 5 to facilitate accurate application of the pressure mold 22 to the slurry. Under the extrusion of the pressure mold 22, the slurry can completely fill the templates 5, and under the heating effect of the pressure mold 22, the slurry gradually dries and solidifies within the templates 5.

[0022] The working process of this utility model is as follows: The circular conveyor belt operates intermittently, with a consistent conveying distance for each run, ensuring that the tray 3 is always present below the loading robot 6, the feeding mechanism 7, the extrusion molding mechanism 8, and the unloading robot 9. First, the loading robot 6 places the empty template 5 from the loading box 10 into the tray 3. Since the size of the limiting groove 4 is slightly larger than the size of the template 5, placing the template 5 is not difficult. Then, the adjusting cylinder 14 of the feeding mechanism 7 adjusts the position of the feeding port 16 downward, bringing the feeding port 16 closer to the template 5, and adding slurry into the template 5 to avoid slurry splashing during feeding. The extrusion molding mechanism 8 lowers the lifting plate 20 via the lifting cylinder 21, causing the die 22 to act on the slurry. The guide port 23 ensures the docking accuracy between the die 22 and the template 5. The size of the limiting groove 4 is slightly larger than that of the template 5, which also provides space for the template 5 to move when docking. The die 22 extrudes the slurry, allowing the slurry to fill the template 5. At the same time, under the heating action of the die 22, the slurry gradually dries and forms. Finally, the unloading robot 9 takes out the template 5 containing the formed slurry and puts it into the unloading box 11. The empty tray 3 is then sent back to the loading robot 6 by the circular conveyor belt to complete the cycle.

[0023] The embodiments described above are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the protection scope of this utility model.
