In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are some, but not all, of the embodiments of this invention.

[0029] The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0030] Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this invention.

[0031] The following is in conjunction with the appendix Figure 1-8 The embodiments of the present invention will be described in detail below.

[0032] Example 1 This invention discloses a robotic dual-gun automatic spraying device, comprising: a robotic arm 1; the robotic arm 1 is fixed to a spraying device by four fixing screws 101; a mounting arm 301 is fixed on the robotic arm 1; two nozzles 302 are fixed on the mounting arm 301; two mounting seats 303 are symmetrically fixed on the mounting arm 301; both mounting seats 303 are L-shaped; each mounting seat 303 is fixed with an electric cylinder 304; the extended ends of the two electric cylinders 304 are fixed on a heating plate 305; the heating plate 305 is electrically connected to an external power supply; the heating plate 305 is in contact with the two nozzles 302; before use, the power supply to the heating plate 305 is turned on; the heat generated by the heating plate 305 can heat and soften the paint at the nozzles 302, preventing the nozzles 302 from clogging; and the heating plate 305 can also prevent dust from entering the nozzles 302.

[0033] Each nozzle 302 is fitted with a heating ring 306. Both heating rings 306 are electrically connected to an external power supply. The two heating rings 306 are auxiliary heating components for the nozzle 302. When in use, the power supply to the heating rings 306 is turned on, and the heat generated by the heating rings 306 can heat and soften the paint at the nozzle 302, further preventing the nozzle 302 from clogging.

[0034] Among them, a paint pump 307 is fixed on the robotic arm 1, and the discharge pipe of the paint pump 307 is connected to two spray nozzles 302.

[0035] The spraying section 3 is composed of the mounting arm 301, the spray nozzle 302, the mounting base 303, the electric cylinder 304, the heating plate 305, and the heating ring 306.

[0036] The robotic arm 1 is welded with four auxiliary seats 102, all of which are ring structures. The inner walls of the four auxiliary seats 102 are in elastic contact with the outer walls of the adjustment points of the four fixing screws 101. During use, the auxiliary seats 102 can prevent the fixing screws 101 from loosening, thus ensuring the stability of the device and the spraying accuracy.

[0037] The robotic arm 1 is equipped with a mixing unit 2, which consists of a barrel 201, a cover plate 202, a hydraulic cylinder 203, a mixing plate 204, and a heating seat 205. The barrel 201 is fixed on the robotic arm 1, and the cover plate 202 is fixed on the barrel 201.

[0038] A hydraulic cylinder 203 is fixed on the cover plate 202. The extended end of the hydraulic cylinder 203 passes through the cover plate 202 and is fixed on the mixing plate 204. The mixing plate 204 slides inside the barrel 201. When the paint is mixed, the hydraulic cylinder 203 can be driven to extend and retract. The hydraulic cylinder 203 drives the mixing plate 204 to extend and retract, thereby accelerating the flow and mixing of the paint.

[0039] A heating seat 205 is fixed to the outside of the barrel 201. The heating seat 205 has a ring structure and is electrically connected to an external power source. When in use, the heat generated by the heating seat 205 when the external power source is turned on can heat the paint inside the barrel 201, thus preventing the paint from cooling.

[0040] A spraying method using a robotic dual-gun automatic spraying device includes the following steps: 01. Before using the robot's dual-gun automatic spraying device, first ensure that all components are securely connected; firmly fix the robotic arm 1 to the spraying equipment using four fixing screws 101, ensuring that the inner walls of the four auxiliary seats 102 are in elastic contact with the outer walls of the adjusting points of the fixing screws 101 to prevent the fixing screws 101 from loosening; next, connect the external power supply to ensure that components such as the heating plate 305, heating ring 306, heating seat 205, and paint pump 307 can operate normally; at the same time, carefully check whether the wiring connections are normal to avoid short circuits, open circuits, and other problems, and prevent malfunctions during operation that could affect the spraying work; 02. Once the equipment is ready, connect the external power supply to the heating base 205. The heating base 205 will then start working, and the heat generated will be transferred to the barrel 201 to preheat the paint inside the barrel 201, preventing the paint from cooling and thickening. After preheating for a period of time, start the hydraulic cylinder 203. The extended end of the hydraulic cylinder 203 will slowly pass through the cover plate 202, driving the mixing plate 204 to move up and down inside the barrel 201. As the mixing plate 204 extends and retracts, the paint is driven to flow faster, and the different components are fully mixed to ensure the uniformity of the paint and provide a stable quality coating for subsequent spraying work. 03. The fully mixed and heated paint flows out through the discharge pipe of the tank 201. The filter screen installed at the discharge pipe plays its role in filtering the paint, blocking any impurities or particles that may be present, and preventing them from entering the subsequent pipeline, affecting the spraying effect or even damaging the equipment. Subsequently, the paint pump 307 starts, drawing the filtered paint out from the discharge pipe of the tank 201 and delivering it to the spray head 302 through the drain pipe, providing a continuous and stable supply of paint for the spraying operation. 04. Before the actual spraying operation, the nozzle 302 needs to be preheated. The power to the heating plate 305 is turned on, and the heating plate 305 starts working, rapidly transferring the heat to the nozzle 302, softening the paint at the nozzle 302. Simultaneously, the power to the heating ring 306 is turned on, and the heating ring 306, acting as an auxiliary heating element, further heats the paint at the nozzle 302. This dual heating method not only effectively prevents the nozzle 302 from clogging due to paint drying, but also utilizes the heating plate 305 to achieve a dustproof function for the nozzle 302, laying the foundation for stable subsequent spraying operations. 05. Once the nozzle 302 is preheated and the paint is ready, the robotic arm 1 begins to move according to the pre-set program and path. The movement of the robotic arm 1 drives the mounting arm 301 and the two nozzles 302 fixed on it to move, enabling them to accurately reach the position to be sprayed. During the movement of the robotic arm 1, the paint pump 307 works continuously, drawing the mixed, heated, and filtered paint from the tank 201 and stably delivering it to the nozzle 302 through the drain pipe. The nozzle 302 sprays the paint evenly onto the surface of the target object according to the set parameters, completing the entire spraying operation. During the spraying process, parameters such as the movement speed of the robotic arm 1, the angle of the nozzle 302, and the paint flow rate can be adjusted in real time according to actual needs to ensure the best spraying effect.

[0041] Example 2 Based on Example 1, such as Figures 1-8 As shown, the discharge pipe of the barrel 201 is connected to the inlet pipe of the paint pump 307. A filter screen is installed at the discharge pipe of the barrel 201. The paint pump 307 is used to extract the heated paint from the barrel 201 and deliver it to the spray head 302.

[0042] The working principle of this embodiment is as follows: Before using the robotic dual-gun automatic spraying device, first ensure that the connections of all components are secure; firmly fix the robotic arm 1 to the spraying equipment with four fixing screws 101, and ensure that the inner walls of the four auxiliary seats 102 are in elastic contact with the outer walls of the adjustment points of the fixing screws 101 to prevent the fixing screws 101 from loosening; then, connect the external power supply to ensure that the heating plate 305, heating ring 306, heating seat 205, and paint pump 307 can be powered on and operated normally; at the same time, carefully check whether the wiring connections are normal to avoid short circuits, open circuits, and other problems, and prevent malfunctions during operation that may affect the spraying work; when the equipment is ready, connect the external power supply to the heating seat 205. Upon starting the process, the generated heat is transferred to the barrel 201, preheating the paint inside and preventing it from thickening upon cooling. After a period of preheating, the hydraulic cylinder 203 is activated. The extended end of the hydraulic cylinder 203 slowly passes through the cover plate 202, causing the mixing plate 204 to move up and down within the barrel 201. As the mixing plate 204 extends and retracts, the paint is accelerated to flow, ensuring thorough mixing of different components and guaranteeing paint uniformity, thus providing a stable coating for subsequent spraying. The thoroughly mixed and heated paint flows out through the discharge pipe of the barrel 201. The filter screen installed at the discharge pipe functions to filter the paint, blocking any impurities or particles that may be present, preventing them from entering subsequent pipelines and affecting the paint's performance. This can affect the spraying effect or even damage the equipment; subsequently, the paint pump 307 starts, drawing filtered paint from the discharge pipe of the tank 201 and delivering it to the spray head 302 through the drain pipe, providing a continuous and stable paint supply for the spraying operation; before the formal spraying operation, the spray head 302 needs to be preheated; the power to the heating plate 305 is turned on, and the heating plate 305 starts working, and the heat generated is quickly transferred to the spray head 302 in contact with it, causing the paint at the spray head 302 to soften due to heat; at the same time, the power to the heating ring 306 is turned on, and the heating ring 306 acts as an auxiliary heating element to further heat the paint at the spray head 302; through this dual heating method, not only is the spray head 302 effectively prevented from drying out due to the paint, but also... To prevent blockage, the heating plate 305 is used to prevent dust from entering the nozzle 302, laying the foundation for stable subsequent spraying operations. Once the nozzle 302 is preheated and the paint is ready, the robotic arm 1 begins to move according to the pre-set program and path. The movement of the robotic arm 1 drives the mounting arm 301 and the two nozzles 302 fixed on it to move, enabling them to accurately reach the position to be sprayed. During the movement of the robotic arm 1, the paint pump 307 works continuously, drawing the mixed, heated, and filtered paint from the tank 201 and stably delivering it to the nozzle 302 through the drain pipe. The nozzle 302 sprays the paint evenly onto the surface of the target object according to the set parameters, completing the entire spraying operation.During the spraying process, parameters such as the movement speed of the robotic arm 1, the angle of the nozzle 302, and the paint flow rate can be adjusted in real time according to actual needs to ensure the best spraying effect.

Both mounting seats 303 are L-shaped structures, and each mounting seat 303 is fixed with an electric cylinder 304. The extended ends of the two electric cylinders 304 are fixed on a heating plate 305, which is electrically connected to an external power supply and is in contact with the two nozzles 302.

[0044] Furthermore, each of the nozzles 302 is fitted with a heating ring 306, and both heating rings 306 are electrically connected to an external power supply. The two heating rings 306 are auxiliary heating elements for the nozzles 302.

[0046] Furthermore, the mounting arm 301, spray head 302, mounting base 303, electric cylinder 304, heating plate 305 and heating ring 306 together constitute the spraying section 3.

[0047] Furthermore, four auxiliary seats 102 are welded onto the robotic arm 1. All four auxiliary seats 102 are annular structures, and the inner walls of the four auxiliary seats 102 are in elastic contact with the outer walls of the adjustment points of the four fixing screws 101.

[0048] Furthermore, a mixing unit 2 is installed on the robotic arm 1. The mixing unit 2 consists of a barrel 201, a cover plate 202, a hydraulic cylinder 203, a mixing plate 204, and a heating seat 205. The barrel 201 is fixed on the robotic arm 1, and the cover plate 202 is fixed on the barrel 201.

[0049] Furthermore, a hydraulic cylinder 203 is fixed on the cover plate 202. The protruding end of the hydraulic cylinder 203 passes through the cover plate 202 and is fixed on the mixing plate 204. The mixing plate 204 slides inside the barrel 201.

[0050] Furthermore, a heating seat 205 is fixed to the outside of the barrel 201. The heating seat 205 has a ring structure and is electrically connected to an external power supply.

[0051] Furthermore, the discharge pipe of the barrel 201 is connected to the inlet pipe of the paint pump 307, and a filter screen is provided at the discharge pipe of the barrel 201.

[0052] This invention discloses a spraying method for a robotic dual-gun automatic spraying device, which includes the following steps: 01. Before using the robot's dual-gun automatic spraying device, first ensure that all components are securely connected; firmly fix the robotic arm 1 to the spraying equipment using four fixing screws 101, ensuring that the inner walls of the four auxiliary seats 102 are in elastic contact with the outer walls of the adjusting points of the fixing screws 101 to prevent the fixing screws 101 from loosening; next, connect the external power supply to ensure that components such as the heating plate 305, heating ring 306, heating seat 205, and paint pump 307 can operate normally; at the same time, carefully check whether the wiring connections are normal to avoid short circuits, open circuits, and other problems, and prevent malfunctions during operation that could affect the spraying work; 02. Once the equipment is ready, connect the external power supply to the heating base 205. The heating base 205 will then start working, and the heat generated will be transferred to the barrel 201 to preheat the paint inside the barrel 201, preventing the paint from cooling and thickening. After preheating for a period of time, start the hydraulic cylinder 203. The extended end of the hydraulic cylinder 203 will slowly pass through the cover plate 202, driving the mixing plate 204 to move up and down inside the barrel 201. As the mixing plate 204 extends and retracts, the paint is driven to flow faster, and the different components are fully mixed to ensure the uniformity of the paint and provide a stable quality coating for subsequent spraying work. 03. The fully mixed and heated paint flows out through the discharge pipe of the tank 201. The filter screen installed at the discharge pipe plays its role in filtering the paint, blocking any impurities or particles that may be present, and preventing them from entering the subsequent pipeline, affecting the spraying effect or even damaging the equipment. Subsequently, the paint pump 307 starts, drawing the filtered paint out from the discharge pipe of the tank 201 and delivering it to the spray head 302 through the drain pipe, providing a continuous and stable supply of paint for the spraying operation. 04. Before the actual spraying operation, the nozzle 302 needs to be preheated. The power to the heating plate 305 is turned on, and the heating plate 305 starts working, rapidly transferring the heat to the nozzle 302, softening the paint at the nozzle 302. Simultaneously, the power to the heating ring 306 is turned on, and the heating ring 306, acting as an auxiliary heating element, further heats the paint at the nozzle 302. This dual heating method not only effectively prevents the nozzle 302 from clogging due to paint drying, but also utilizes the heating plate 305 to achieve a dustproof function for the nozzle 302, laying the foundation for stable subsequent spraying operations. 05. Once the nozzle 302 is preheated and the paint is ready, the robotic arm 1 begins to move according to the pre-set program and path. The movement of the robotic arm 1 drives the mounting arm 301 and the two nozzles 302 fixed on it to move, enabling them to accurately reach the position to be sprayed.

The nozzle 302 sprays the paint evenly onto the surface of the target object according to the set parameters, completing the entire spraying operation. During the spraying process, parameters such as the movement speed of the robotic arm 1, the angle of the nozzle 302, and the paint flow rate can be adjusted in real time according to actual needs to ensure the best spraying effect.

[0053] The robotic arm of this application is securely mounted on the spraying equipment with four fixed screws. Combined with the elastic contact of the ring auxiliary seat, it can effectively prevent the screws from loosening, ensuring the stability of the device operation and the spraying accuracy, thus laying the foundation for precise operation.

[0054] The dual heating design of the spraying section in this application has significant advantages. The heating plate is in close contact with the nozzle under the drive of the electric cylinder, which not only preheats and softens the paint to prevent nozzle clogging, but also provides dust protection. The heating ring fitted at the nozzle serves as an auxiliary heating component, further enhancing the heating effect, significantly reducing the probability of clogging, and ensuring continuous and smooth spraying operations.

[0055] The mixing section of this application achieves integrated paint processing. The hydraulic cylinder drives the mixing plate to extend and retract within the barrel, accelerating paint flow and mixing, and improving paint uniformity. The annular heating seat heats the barrel, preventing the paint from cooling and solidifying, and ensuring good paint flowability.

[0056] The filter screen at the discharge pipe of the barrel in this application can filter impurities, and work with the paint pump to stably deliver paint, reducing the risk of nozzle clogging.

[0057] The entire device integrates functions such as paint mixing, heating, conveying, and spraying. Through the coordinated operation of various components, it effectively solves problems such as easy cooling of paint, uneven mixing, and easy clogging of nozzles in traditional spraying, significantly improving spraying efficiency and quality, reducing equipment maintenance costs, and is suitable for spraying operation needs in a variety of scenarios.

[0058] Thus, the objective of this invention has been achieved.

[0059] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
