Description

Technical Field

[0001] This utility model relates to the field of precision shell making technology, and in particular to a vacuum paste dipping production line. Background Technology

[0002] In the field of high-end manufacturing, precision casting is a key process. As the core carrier of precision casting, the quality of the mold shell directly determines the quality of the casting. Therefore, the optimization and upgrading of precision shell making technology plays an important supporting role in the development of the high-end manufacturing industry.

[0003] The manufacturing process of precision mold shells mainly includes key steps such as mold shell preparation, slurry application, sanding, drying, dewaxing, and firing. Among these, the slurry application step is the foundation for the formation of the mold shell coating, and its process effect directly affects the adhesion of the subsequent sanding, the uniformity of the coating, and the final density of the mold shell. With the improvement of automation levels in the industry, traditional manual slurry application, due to its low efficiency, poor operational consistency, and high labor intensity, has gradually been replaced by automatic slurry application equipment. Automatic slurry application equipment drives the mold shell to complete the slurry coverage and drainage, significantly improving the production efficiency and operational stability of the slurry application process.

[0004] Based on the above, the existing slurry has two problems: one is that the surface slurry thickness is uneven, and the other is that there are air bubbles in the surface slurry. Both of these will affect the molding quality of the mold shell and need to be further improved. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a vacuum paste-coating production line.

[0006] A vacuum slurry production line designed for this purpose includes a slurry tank, a vacuum machine, a sander, an air blowing module, and a multi-axis robot.

[0007] The slurry-coating bucket is used to coat the workpiece with slurry;

[0008] The air blowing module is positioned above the slurry tank and is used to blow air onto the workpiece after it has been slurry coated.

[0009] The vacuum machine is used to vacuum the workpiece;

[0010] The sanding machine is used to sand the workpiece after it has been coated with slurry;

[0011] The multi-axis robot is connected to a clamp for gripping workpieces. The multi-axis robot can grip the workpieces and move them to a slurry tank, vacuum machine, sander, or air blowing module for processing.

[0012] Preferably, the air blowing module includes at least a support and an air blowing element, wherein the air blowing element is connected to the support and is located above the slurry dipping tank;

[0013] The blowing element has an internal air passage, and the surface of the blowing element has a blowing hole and an air inlet that communicate with the air passage.

[0014] Preferably, the bracket is connected to a crossbar, and a plurality of connecting rods are arranged on the crossbar along its extension direction; the number of the air blowing elements is the same as the number of the connecting rods and they are interconnected.

[0015] Preferably, the connecting rod is provided with a connecting seat, and the air blowing element is connected to an adjusting rod, the adjusting rod being rotatably connected to the connecting seat.

[0016] Preferably, the dipping tank includes a frame, a tank body rotatably disposed relative to the frame, and a stirring paddle extending into the tank body; a drive motor for driving the tank body to rotate is provided on the frame.

[0020] Compared with existing technologies, this invention precisely solves the problems of traditional paste adhesion and has the following beneficial effects:

[0021] Precise thickness control improves mold shell consistency: After slurry application, excess slurry is quickly blown away by the air blowing module. Combined with the precise operation of the multi-axis robot for uniform slurry application and smooth movement, the slurry thickness is effectively controlled. The standardized movements of the robot avoid human differences, greatly improve the consistency of slurry thickness in batch mold shells, and reduce dimensional deviations.

[0022] Eliminating air bubbles in the slurry and ensuring the density of the mold shell: After air blowing to control the thickness, the workpiece is vacuumed by a vacuum machine, which can efficiently remove air bubbles that adhere to the slurry during the dipping process, prevent the mold shell coating from forming pores due to air bubbles, further improve the density of the coating, and lay a solid foundation for the subsequent sand adhesion and casting quality.

[0023] Automation improves efficiency and reduces labor intensity: Multi-axis robotic arms complete workpiece gripping and transfer of each process in a continuous manner without human intervention; seamless connection between each link enables continuous and stable production, increases the processing volume per unit time, and reduces manual input and labor intensity.

[0038] See Figures 1-6 A vacuum slurry dipping production line includes a slurry dipping tank 10, a vacuum machine 20, a sanding machine 30, an air blowing module 40, and a multi-axis robot 50. The slurry dipping tank 10 is used to dip workpieces in slurry. The air blowing module 40 is positioned above the slurry dipping tank 10 and is used to blow air onto the dipped workpieces. The vacuum machine 20 is used to vacuum the workpieces. The sanding machine 30 is used to sand the dipped workpieces. The multi-axis robot 50 is connected to a clamp for gripping workpieces. The multi-axis robot 50 can grip the workpieces and move them to the slurry dipping tank 10, the vacuum machine 20, the sanding machine 30, or the air blowing module 40 for processing.

[0039] The vacuum coating production line uses a multi-axis robot 50 as its core transmission carrier. Through the fixtures connected to the robot, it achieves fully automated transfer of workpieces throughout the entire process. All equipment works together according to a preset process to complete the precision mold coating process (the vacuum machine 20 and the sanding machine 30 are both existing mature products, requiring no additional development). The specific working principle is as follows:

[0040] First, the multi-axis robot arm 50 precisely grips the workpiece to be processed using a fixture, and drives the workpiece to move into the slurry tank 10 according to the program, so that the workpiece is completely immersed in the slurry. After the slurry fully adheres to the surface of the workpiece, the robot arm drives the workpiece to smoothly detach from the slurry tank 10, completing the slurry dipping process.

[0041] Next, the robotic arm carries the workpiece after it has been coated with slurry to a position below the air blowing module 40 located above the slurry tank 10. The air blowing module 40 is activated and sprays airflow onto the surface of the workpiece to quickly remove excess slurry from the surface of the workpiece. At the same time, it helps to adjust the adhesion of the slurry on the surface of the workpiece, laying the foundation for a uniform coating in subsequent processes.

[0042] Subsequently, the multi-axis robot 50 continues to transfer the workpiece that has completed the air blowing process to the vacuum machine 20 (the vacuum machine 20 is an existing product with stable and reliable vacuuming performance). The vacuum machine 20 starts the vacuuming program, and by reducing the air pressure inside the machine, it efficiently removes the air and bubbles remaining in the slurry on the surface of the workpiece, avoids the formation of pores in the mold shell coating, and further optimizes the density of the coating.

[0043] Finally, after the vacuuming process is completed, the multi-axis robot arm 50 grasps the workpiece, removes it from the vacuum machine 20, and transfers it to the sanding machine 30. The sanding machine 30 can be either a readily available, mature floating sander or a sand spraying machine, which can be flexibly selected based on the workpiece characteristics and production needs: if a floating sander is used, airflow suspends the sand particles and evenly covers the workpiece surface; if a sand spraying machine is used, sanding is completed through sand particle spraying. Both types of equipment can stably achieve sanding treatment of the workpiece after slurry application. At this point, a complete processing flow for the vacuum slurry production line is completed. Subsequently, depending on production needs, the robot arm can carry the workpiece into the next cycle or transfer it to subsequent processes.

[0044] In this utility model, the multi-axis robotic arm 50 precisely grips the workpiece to be processed using a fixture. The fixture adopts existing technology, such as the Chinese utility model patent, announcement number CN221539845U, which discloses a robotic shell-making three-grip self-rotating gripper.

[0045] In this invention, the air-blowing module 40 includes at least a support 410 and an air-blowing element 400. The air-blowing element 400 is connected to the support 410 and located above the slurry-coating tank 10. The air-blowing element 400 has an internal air channel, and its surface has air-blowing holes and air inlets communicating with the air channel. In use, the air inlet is connected to an external air supply device via an air pipe. During use, the external air supply device (existing technology, requiring no additional development) is connected to the air inlet of the air-blowing element 400 via an air pipe. Gas enters the internal air channel of the element through the air inlet and is then ejected from the air-blowing hole, quickly removing excess slurry from the surface of the workpiece after slurry application. Simultaneously, it helps adjust the slurry adhesion state, creating a uniform coating for subsequent processes.

[0046] See Figure 4 and Figure 5 The bracket 410 is connected to a crossbar 420, and several connecting rods 430 are arranged along the extension direction of the crossbar 420. The number of air blowing elements 400 is the same as the number of connecting rods 430 and they are interconnected. By connecting the crossbar 420 and arranging several connecting rods 430 along the extension direction of the crossbar 420, the bracket 410 connects to one air blowing element 400. This not only stably fixes multiple air blowing elements 400, but also ensures that the air blowing elements 400 are evenly distributed along the crossbar direction. This ensures that the sprayed airflow can fully cover the surface of the workpiece after slurry application, more efficiently removes excess slurry, adjusts the slurry adhesion state, and ensures coating uniformity.

[0047] In this utility model, regarding the fixing of the bracket 410, it can be fixedly connected to the frame 110 of the dipping tank 10, so that the blowing element 400 can be located above the tank body 120 while achieving fixed installation.

[0048] See Figure 4 and Figure 5 The connecting rod 430 is provided with a connecting seat 450, and the air blowing element 400 is connected to an adjusting rod 440, which is rotatably connected to the connecting seat 450. The connecting seat 450 of the connecting rod 430 is rotatably connected to the adjusting rod 440 of the air blowing element 400. This rotatable connection uses an existing connection structure and requires no additional design. By rotating the adjusting rod 440, the jet angle of the air blowing element 400 can be flexibly adjusted to adapt to workpieces of different sizes and shapes, ensuring that the airflow accurately acts on the workpiece surface. If stable rotation is required, a damped rotation connection structure can be used to prevent the air blowing element 400 from shifting its angle due to airflow impact during the blowing process, further ensuring the blowing effect.

[0049] See Figure 6The slurry dipping tank 10 includes a frame 110, a tank body 120 rotatably disposed relative to the frame 110, and a stirring paddle 130 extending into the tank body 120. A drive motor 150 for driving the tank body 120 to rotate is mounted on the frame 110. In the slurry dipping tank 10, the drive motor 150 on the frame 110 can drive the tank body 120 to rotate relative to the frame 110. Simultaneously, the stirring paddle 130 inside the tank body 120 works in concert to continuously stir the slurry in the tank, preventing slurry sedimentation and stratification, and ensuring uniform slurry concentration. The rotation of the tank body combined with stirring also allows the workpiece to fully contact the slurry during dipping, ensuring that the slurry adheres evenly to the workpiece surface, laying a good foundation for subsequent processes.

[0050] See Figure 4 A level gauge 140 is installed above the barrel 120 and is fixedly mounted on the frame 110. The level gauge 140 (using an existing product, requiring no additional development) is fixedly installed on the frame 110 above the barrel 120 of the slurry-coating tank 10. It can monitor the slurry level in the barrel 120 in real time, allowing operators to promptly determine the remaining slurry level. When the level falls below a preset value, slurry can be replenished in time to prevent insufficient slurry coating on the workpiece, ensuring the stable and continuous operation of the slurry coating process.

[0051] See Figure 6 The motor shaft of the drive motor 150 is provided with a first synchronous pulley 160, the bottom of the barrel 120 is connected to a rotating shaft, the rotating shaft is connected to a second synchronous pulley 180, and the first synchronous pulley 160 and the second synchronous pulley 180 are fitted with a synchronous belt 170.

[0052] See Figure 4 and 6 The stirring paddle 130 is fixedly connected to the frame 110.

[0053] See Figure 1 During production, a first conveyor line 60 and a second conveyor line 70 are respectively set up next to this production line. Both the first conveyor line 60 and the second conveyor line 70 adopt existing overhead conveyor lines. They are used to transport workpieces. The multi-axis robot arm 50 can grasp the workpieces from the first conveyor line 60. After the workpieces are processed, the robot arm grasps the workpieces and places them on the hangers of the second conveyor line 70.
