[0063] Based on this, the application provides an automatic spraying machine, as shown in Figure 1 and Figure 2 The automatic spraying machine includes a base 10, a spraying assembly 30, a first driving assembly 20, and a second driving assembly 40.

[0064] The first driving assembly 20 is installed on the base 10, the spraying assembly 30 is connected with the first driving assembly 20, and the first driving assembly 20 is used to drive the spraying assembly 30 to move in a first direction.

[0066] Among them, a first protection structure 50 is arranged at the connection between the first driving assembly 20 and the spraying assembly 30, and a second protection structure 60 is arranged at the connection between the second driving assembly 40 and the spraying assembly 30, and the first protection structure 50 and the second protection structure 60 are used to block the water mist from entering the inside of the first driving assembly 20 and the second driving assembly 40.

[0067] The automatic spraying machine provided by the embodiment of the application can effectively prevent water mist from corroding the transmission structure in the driving assembly, thereby prolonging the service life of the driving assembly.

[0068] In application, through the cooperative work of the first driving assembly 20 and the second driving assembly 40, the spraying assembly 30 can move in two mutually perpendicular directions, thereby covering a larger spraying area and realizing a more complex spraying path. By using a high-precision transmission mechanism and a control system, the spraying machine can accurately control the spraying position, ensuring the consistency and accuracy of each spraying. The first protective structure 50 and the second protective structure 60 are specially designed to effectively prevent water mist from entering the driving assembly, thereby improving the reliability and service life of the equipment. The spraying machine can preset a spraying program to automatically complete the spraying task, reduce manual intervention, and improve production efficiency.

[0069] The automatic spraying machine provided by the application is suitable for various application scenarios that require accurate spraying, especially in the die casting industry, which can help realize efficient cooling and lubrication of the mold, while ensuring the quality and production efficiency of the castings. In addition, the automatic spraying machine provided by the application can also be applied to other fields that require fine spraying, such as automobile manufacturing, electronic component spraying, food processing, etc.

[0070] In application, the first protective structure 50 is arranged at the connection between the first driving assembly 20 and the spraying assembly 30, and the second protective structure 60 is arranged at the connection between the second driving assembly 40 and the spraying assembly 30. The main function of these protective structures is to block water mist from entering the driving assembly, preventing electrical faults or mechanical component corrosion caused by water.

[0071] The protective structure described above can include sealing rings, waterproof covers and other materials, and can even be integrated with drainage or flow guide designs to further improve the protection effect.

[0072] It should be noted that the first direction described above refers to the length direction of the first driving assembly 20, i.e. the X direction in the figure, and the second direction refers to the length direction of the second driving assembly 40, i.e. the Z direction in the figure. The above is only for the convenience of understanding the technical solutions of the application and should not be understood as a limitation on the protection scope of the embodiments of the application.

[0073] In some embodiments, as shown in Figures 1 to 3 The first driving assembly 20 includes a mounting frame 21, a first motor 22, and a first lead screw 23.

[0074] The mounting frame 21 is connected to the base 10;

[0075] The first motor 22 is installed on the side of the mounting frame 21 away from the spray assembly 30;

[0076] One end of the first lead screw 23 is connected to the output end of the first motor 22, and the other end of the first lead screw 23 is connected to the spray assembly 30. In this way, the lead screw drive system can provide extremely high positioning accuracy, which is suitable for occasions with strict requirements on spraying position. Compared with other types of transmission methods, the lead screw drive has better stability and durability, and can maintain accurate movement performance for a long time. The key components such as the lead screw and the motor are relatively independent, which is convenient for maintenance and replacement, and reduces maintenance cost.

[0077] The mounting frame 21 serves as the main support structure of the first drive assembly 20, and is connected to the base 10 to ensure the stability and firmness of the entire first drive assembly 20. In application, the mounting frame 21 is a box body with a closed four sides, leaving only one end for the first lead screw 23 to extend out and connect to the spray assembly 30, which can effectively improve the mechanical strength and rigidity, and the sealing performance of the entire first drive assembly 20, thereby preventing water mist or other spraying media from entering the mounting frame 21 and corroding the first lead screw 23. The first motor 22 can be a servo motor or a stepper motor, which is used to provide precise rotary power. The motor is usually equipped with an encoder for feedback position information, realizing closed-loop control and ensuring the accuracy of movement. One end of the first lead screw 23 is connected to the output end of the first motor 22, and the other end is connected to the spray assembly 30, which converts the rotary motion of the motor into linear motion through rotation. In some embodiments, the first lead screw 23 is usually made of high-strength materials such as stainless steel or hardened steel to ensure wear resistance and long service life. Bearings can be provided at both ends of the first lead screw 23 to reduce friction and improve the smoothness of operation.

[0078] In some embodiments, the first protective structure 50 is an organ case, which is arranged at the connection between the first lead screw 23 and the spray assembly 30, and covers the end of the first lead screw 23. In this way, water mist or other spraying media can be effectively prevented from entering the first lead screw. Further, in order to prevent water or other spraying media from entering the interior of the first motor 22, a sealing ring or other waterproof device can be arranged at the connection between the motor and the mounting frame 21. As shown in Figure 1 The organ case (i.e. the first protective structure 50) is installed between the lead screw and the spray assembly 30, which not only plays a waterproof role, but also protects the lead screw from external pollutants.

[0079] In some embodiments, as shown in Figures 1 to 3 The second drive assembly 40 includes a fixing frame 41, a second motor 42, and a second lead screw 43;

[0080] The fixed frame 41 is connected to the spray assembly 30;

[0081] The second motor 42 is installed at one end of the fixed frame 41 away from the spray assembly 30;

[0082] The second lead screw 43 is arranged in the second direction, one end of the second lead screw 43 is connected to the output end of the second motor 42, and the other end of the second lead screw 43 extends towards the side close to the spray assembly 30. In this way, by using the lead screw drive system, the second drive assembly 40 realizes the precise linear movement of the spray assembly 30 in the second direction, combined with waterproof protection measures, ensuring the reliability and long service life of the equipment. This design not only improves the precision and efficiency of spraying, but also provides a solid technical guarantee for complex spraying tasks. Working together with the first drive assembly 20, multi-axis linkage can be realized, further improving the flexibility and adaptability of the automatic spraying machine.

[0083] In some embodiments, as shown in Figure 3 and Figure 6 The fixed frame 41 includes a fixed end 411, a moving end 412, and a guide shaft 413;

[0084] The fixed end 411 is away from one end of the spray assembly 30, and the second motor 42 is arranged on the side of the fixed end 411 away from the moving end 412;

[0085] The moving end 412 is connected to the first drive assembly 20; in other embodiments, the moving end 412 can also be directly connected to the spray assembly 30;

[0086] One end of the guide shaft 413 is connected to the fixed end 411, the middle part of the guide shaft 413 is connected to the moving end 412, and the other end of the guide shaft 413 is connected to the spray assembly 30. In this way, through the cooperation of the fixed end 411, the moving end 412 and the guide shaft 413, the spray assembly 30 can realize high-precision linear movement in two directions, ensuring consistent and accurate position of each spraying. The stable triangular support structure and the design of the guide shaft 413 greatly improve the anti-vibration performance and running stability of the system, which can maintain good working condition even under high speed or heavy load conditions. The use of the guide shaft 413 reduces the load of the lead screw and the motor, reduces wear and tear, prolongs the service life of key components, and reduces maintenance costs.

[0087] In application, the fixed end 411 is away from one end of the spray assembly 30. As the support point of the entire second drive assembly 40, the fixed end 411 is installed with the second motor 42, ensuring the stability and reliability of the motor during operation. A stable mounting platform is provided to enable the motor to run smoothly, reducing the impact of vibration on the lead screw transmission. It is convenient for maintenance and repair, and the position of the motor is relatively independent and will not be disturbed by the movement of the spray assembly 30. The moving end 412 serves as the connection point of the spray assembly 30 or the first drive assembly 20, and the moving end 412 moves along the second direction (Z-axis) together with the spray assembly 30. It ensures that the spray assembly 30 maintains the correct posture and position during movement, avoiding uneven spraying due to deviation. Through the connection with the first drive assembly 20, multi-axis linkage is realized, further improving the positioning accuracy and flexibility of the spray assembly 30.

[0088] In application, as shown in Figure 2 , Figure 4 and Figure 6 , the guide shaft 413 is provided with two, and the two guide shafts 413 are located on both sides of the second lead screw 43. One end of the guide shaft 413 is connected to the fixed end 411, the middle part is connected to the moving end 412, and the other end is connected to the spray assembly 30. Its role is to provide linear guidance and ensure accurate movement of the spray assembly 30 along the predetermined path during movement. The presence of the guide shaft 413 can significantly reduce the lateral deviation of the spray assembly 30 during movement, ensuring that it always moves along a straight path, thereby improving the accuracy of spraying. The guide shaft 413 is also equipped with a sliding bearing or a linear guide rail, which reduces frictional resistance and ensures smooth movement of the spray assembly 30 during movement, avoiding jamming.

[0089] In some embodiments, as shown in Figure 2 and Figure 6 , the second protective structure 60 includes a first sleeve 61, which is sleeved on the second lead screw 43, one end of the first sleeve 61 is connected to one end of the second lead screw 43, the other end of the first sleeve 61 is connected to the spray assembly 30, and there is a gap between the first sleeve 61 and the second lead screw 43. The first sleeve 61 is sleeved on the second lead screw 43 and connected to the spray assembly 30, forming a closed channel that effectively blocks water mist, cooling liquid and other contaminants from entering the lead screw. In this way, the first sleeve 61 effectively prevents external water mist or other spraying media from entering the first sleeve 61 without affecting the rotation of the second lead screw 43, thereby preventing the second lead screw 43 from being eroded and improving its service life.

[0090] In application, the first sleeve 61 can prevent moisture and impurities from entering the inside of the lead screw, reducing corrosion and wear, and prolonging the service life of the lead screw and related mechanical components. Ensure the normal operation of the lead screw transmission system, avoid the problem of jamming or failure caused by pollution, improve the reliability and stability of the equipment. Since there is no direct contact between the first sleeve 61 and the second lead screw 43, the friction is reduced, the wear is reduced, and the service life of the second lead screw 43 is further prolonged. Reduce errors caused by friction, ensure that the movement of the spray assembly 30 is smoother and more accurate. The design of the first sleeve 61 plays an important role in protecting the second lead screw 43 and related components, by preventing water and dust, reducing friction and wear, keeping clean, adapting to thermal expansion, and providing additional support, significantly improving the reliability and durability of the equipment. This design not only optimizes the spraying process, but also provides a more flexible and accurate solution for complex spraying tasks.

[0091] In some embodiments, as shown in Figure 2 and Figure 6 , the second protective structure 60 further includes a second sleeve 62, which is sleeved on the first sleeve 61, and the two ends of the first sleeve 61 are connected with the fixed end 411 and the moving end 412 respectively. The second sleeve 62 is sleeved outside the first sleeve 61, further forming a closed protective layer, effectively blocking water mist, cooling liquid and other contaminants from entering the inside of the lead screw.

[0092] In application, the double-layer design of the first sleeve 61 and the second sleeve 62 provides stronger protection, ensuring that the lead screw and related mechanical components are completely unaffected by the external environment. Further reduce the invasion of moisture and impurities, significantly prolong the service life of the lead screw and other key components. The second sleeve 62 can effectively isolate the vibration, impact and other mechanical interference in the external environment, protecting the internal transmission system. Reduce the influence of external vibration on the lead screw transmission, ensure that the movement of the spray assembly 30 is more stable and accurate. The cooperation between the second sleeve 62 and the first sleeve 61 can form a more airtight seal, preventing water mist and cooling liquid from seeping in from the gap. The design of double-layer sleeve greatly improves the sealing effect, ensuring that the lead screw and other key components such as motors always remain dry and clean. Reduce the maintenance requirements caused by liquid infiltration, reduce operating costs. The second sleeve 62 not only plays a protective role, but also provides additional support for the first sleeve 61, especially in long-stroke applications. Increase the rigidity of the entire transmission system, reduce bending and vibration, improve the stability and accuracy of movement. When bearing a larger load, the second sleeve 62 can share part of the force, reduce the burden of the first sleeve 61, and ensure its long-term stable operation.

[0093] In some embodiments, as shown in Figure 2As shown, the guide shaft 413 is hollow, and the guide shaft 413 is internally provided with a pipeline 70 for providing spray medium and compressed air to the spray assembly 30. In this way, the wiring and pipeline 70 layout are simplified, the pipeline 70 for providing spray medium and compressed air is integrated into the guide shaft 413, and the number and complexity of external pipelines are reduced. The external pipelines are avoided, the appearance of the equipment is more simple and neat, and the equipment is convenient for maintenance and cleaning. The space required by the external pipelines is saved, the overall structure of the equipment is more compact, the production and maintenance costs are reduced through integrated design, and the assembly efficiency of the equipment is improved.

[0094] In some embodiments, as shown in FIG. 1, the base 10 includes a mounting plate 11, a support 12, and a connecting frame 13. Figures 4 to 6

[0095] The mounting plate 11 is distributed on both sides of the spray assembly 30, and the mounting plate 11 is used to be connected with the head plate of the die casting machine.

[0096] The support 12 is connected with the first driving assembly 20; in a specific embodiment, the support 12 is connected with the mounting frame 21.

[0097] The two ends of the connecting frame 13 are respectively connected with the mounting plate 11 and the support 12.

[0098] Among them, the connecting frame 13 is inclinedly arranged from the end close to the mounting plate 11 to the end close to the support 12, and the direction is gradually away from the spray assembly 30. In this way, the mounting surface of the head plate of the die casting machine for installing the automatic spray machine is small, and after being fixed through the mounting plate 11, the base 10 structure effectively adapts to the characteristics of the small mounting surface of the head plate of the die casting machine through the inclinedly arranged connecting frame 13, and ensures that the automatic spray machine can be stably installed in the limited space. The triangular support structure and the reasonable connection mode enhance the rigidity and stability of the base 10, reduce the vibration and displacement of the equipment in the working process, and improve the precision and reliability of the spray. Through the reasonable layout of the mounting plate 11, the support 12 and the connecting frame 13, the structure of the base 10 fully utilizes the limited space, so that the equipment is more compact and suitable for various installation environments. The inclinedly arranged connecting frame 13 provides more degrees of freedom for the movement of the spray assembly 30, avoids interference with other components, and ensures smooth work when multiple axes are linked.

[0099] In some embodiments, as shown in FIG. 1, the base 10 includes a mounting plate 11, a support 12, and a connecting frame 13. Figures 1 to 6 ​As shown, the support 12 includes a body provided on the first drive assembly 20 and a support shaft 121 provided on the body in the second direction, one end of the support shaft 121 away from the body is provided with a spray medium interface and a compressed air interface, the automatic spraying machine further includes a pipeline 70, one end of the pipeline 70 is in communication with the spray medium interface and the compressed air interface, and the pipeline 70 is arranged along the first drive assembly 20 and the second drive assembly 40, the other end of the pipeline 70 is connected with the spraying assembly 30. In application, the pipeline 70 is integrated by a hose, including an air pipe and a water pipe, and the hose has a certain redundant length. In this way, even during movement, there will be no pulling to cause damage to the pipeline 70.

[0100] In application, the spray medium interface and the compressed air interface are centrally arranged at one end of the support shaft 121, facilitating quick connection and disconnection, and reducing installation and maintenance time. The operator only needs to perform connection operation at one position, improving work efficiency and reducing the risk of errors. The design of the interface and the pipeline 70 takes into account the sealing and safety, reducing the possibility of leakage and ensuring stable operation of the system. Through efficient fluid transmission, it ensures that the spraying assembly 30 can obtain stable supply of spray medium and compressed air, improving the precision and consistency of spraying. The pipeline 70 is arranged along the drive assembly, reducing the number and complexity of external pipelines, making the device more compact and suitable for narrow working environments. Avoiding messy external pipelines makes the appearance of the device more neat and tidy, facilitating maintenance and cleaning. The centrally arranged interface and integrated pipeline 70 design make maintenance and repair more convenient, reducing troubleshooting time and difficulty. By reducing the use of external pipelines, maintenance costs and workload are reduced, prolonging the service life of the device. The pipeline 70 is arranged along the drive assembly, ensuring that the spraying assembly 30 can move freely when multiple axes are linked, without being limited by external pipelines, adapting to complex spraying paths. Reasonable pipeline 70 layout avoids interference with other components, ensuring smooth operation of the device during operation.
