Description

Technical Field

[0001] This utility model relates to a rotary spraying mechanism for a manual spray gun and an industrial robot, belonging to the field of spray gun technology. Background Technology

[0002] In manufacturing, coating is a crucial step, enhancing not only product aesthetics but also weather resistance, corrosion resistance, and UV protection. Coating processes in manufacturing are primarily divided into automated spraying by industrial robots and traditional manual spraying. Automated spraying by industrial robots utilizes advanced spraying technology and precise control systems to ensure uniform coating thickness, eliminates missed areas, and guarantees stable and reliable coating quality. Furthermore, automated spraying enables automated and continuous production, significantly improving efficiency and shortening production cycles. It can also be programmed to meet the coating requirements of different products, offering high adaptability and flexibility. Automated spraying by industrial robots also reduces worker exposure to harmful coatings, lowering occupational disease risks, making operation safer, and minimizing accidents caused by human error. Traditional manual spraying, on the other hand, is manually operated, requiring operators to hold spray guns. This is not only labor-intensive but also makes it difficult to guarantee coating quality and uniformity, and poses safety hazards and emission issues.

[0003] Meanwhile, industrial robot automated spraying and traditional manual spraying use two different types of spray guns with different principles, structures, and operating methods: automatic spray guns and handheld spray guns. Automatic spray guns require no manual operation and are controlled automatically via a control cabinet, suitable for automated coating lines or robotic arms. Handheld spray guns, on the other hand, require constant manual operation, relying on the hand to grip the gun. Operating a handheld spray gun requires attention to techniques such as spray gun movement speed, trigger control, gun distance, and grip posture. The liquid flow rate of a handheld spray gun is controlled by the trigger; the deeper the trigger is pulled, the faster the liquid flow rate.

[0004] Currently, automated painting of industrial robots requires the use of automatic spray guns, which are inherently more expensive than manual spray guns. Furthermore, adjusting the paint flow rate of an automatic spray gun requires components such as proportional valves, which are themselves costly. This results in a high cost when directly applying automatic or manual spray guns to industrial robot painting, especially when adjusting the paint flow rate. While manual spray guns allow for easy control of paint flow rate and spray width by manually adjusting the trigger depth, applying manual spray guns to robots necessitates addressing the issue of adjusting the paint flow rate, for which there is currently no cost-effective solution.

[0028] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various elements, these elements should not be limited to these terms. These terms are only used to distinguish elements of the same type from one another. For example, without departing from the scope of this disclosure, a first element may also be referred to as a second element, and similarly, a second element may also be referred to as a first element.

[0029] Reference Figures 1 to 4 In some embodiments, the rotary spraying mechanism and industrial robot of the manual spray gun according to the present invention include a driver 100 for receiving instructions from the industrial robot and a helical cam 200. The helical cam 200 is connected to the driver 100 to rotate the helical cam 200, thereby pressing or releasing the trigger 410 of the manual spray gun 400.

[0030] Specifically, see Figure 1 and Figure 2 , Figure 4 The spiral cam 200 of this utility model embodiment is provided with an arc-shaped side surface, a highest point, and a lowest point. The highest point and the lowest point are respectively located on the arc-shaped side surface. When the driver 100 drives the spiral cam 200 to rotate, the arc-shaped side surface, the highest point, or the lowest point of the spiral cam 200 can contact the trigger 410 of the manual spray gun 400. Thus, by adjusting the rotation angle of the spiral cam 200, the depth of the spiral cam 200 pressing the trigger 410 can be adjusted, thereby realizing the adjustment of the spraying amount of the manual spray gun 400.

[0031] Furthermore, after receiving instructions from the industrial robot, the driver 100 rotates the helical cam 200 to the required angle according to the spraying volume demand. Simultaneously, the industrial robot can receive feedback from the driver 100 and adjust the depth of trigger 410 pressure, allowing the industrial robot to adjust the spraying volume of the manual spray gun 400. It is understood that when the lowest point of the helical cam 200 contacts the trigger 410 of the manual spray gun 400 but without applying pressure, the manual spray gun 400 is not operating. Conversely, when the highest point of the helical cam 200 contacts the trigger 410 of the manual spray gun 400, the manual spray gun 400 reaches the maximum spraying volume controllable by the rotary spraying mechanism. Furthermore, different points on the curved side of the helical cam 200 contact the trigger 410 of the manual spray gun 400, resulting in different trigger pressures and thus different spraying volumes from the manual spray gun 400.

[0032] This invention adds an electrically driven trigger 410 to the manual spray gun 400 to automatically spray, enabling the trigger 410 of the manual spray gun 400 to automatically control the depth of the press. This allows the manual spray gun 400 to be used on industrial robot automatic spraying equipment, and in some applications, it can replace the automatic spray gun, effectively reducing the cost of use.

[0033] In some embodiments, the driver 100 drives the spiral cam 200 to rotate, adjusting the contact position between the spiral cam 200 and the trigger 410 of the manual spray gun 400, thereby adjusting the spraying amount of the manual spray gun 400. Further, the driver 100 of this invention is a rotary driver 100, with its rotation shaft fixedly connected to the spiral cam 200. Specifically, the rotation shaft of the driver 100 is directly connected to the spiral cam 200, making the structure simpler and easier to adjust.

[0034] It should be noted that this utility model can select a micro motor with suitable dimensions and torque. A spiral cam 200 is installed on the output shaft of the micro motor. Because the spiral cam 200 is spiral-shaped, the micro motor drives the spiral cam 200 to rotate to different angles, which can adjust the pressing depth of the servo motor of the manual spray gun 400, thereby controlling the different spraying amounts of the manual spray gun 400. It can be understood that the drive circuit of the driver 100 can be directly connected to the control system of the industrial robot to achieve linkage control. Furthermore, in this embodiment of the utility model, the driver 100 is a micro servo motor or servo motor, which can effectively reduce the space occupied by the rotary spraying mechanism and facilitate the use of industrial robots in different scenarios.

[0035] In some embodiments, see Figures 1 to 3 The rotary spraying mechanism of this utility model also includes a mounting base 300, which has a fixing hole 310 in which the driver 100 is fixed. Further, the mounting base 300 includes a fixing block 330, and the fixing hole 310 is located on the fixing block 330. Specifically, connecting blocks 340 are connected to both sides of the driver 100. Both the connecting blocks 340 and the fixing blocks 330 have threaded holes. Screws are inserted into the threaded holes of the connecting blocks 340 and the fixing blocks 330 and tightened, thus fixing the driver 100 to the fixing blocks 330. The output shaft of the driver 100 is located on its upper side, and the helical cam 200 is fixed to the output shaft.

[0036] In some embodiments, the mounting base 300 is provided with a connection hole 320. When the spiral cam 200 rotates to its initial position and the handle 420 of the manual spray gun 400 is inserted into the connection hole 320, the trigger 410 of the manual spray gun 400 contacts the lowest point of the spiral cam 200 without generating pressure between them, and the manual spray gun 400 does not operate. Furthermore, the connection hole 320 and the fixing hole 310 are on the same straight line. Specifically, the center line of the connection hole 320 and the center line of the fixing hole 310 are on the same straight line, so that the spiral cam 200 is on the left side of the connection hole 320, and when the manual spray gun 400 is inserted into the connection hole 320, the trigger 410 of the manual spray gun 400 just contacts the spiral cam 200, thereby simplifying the overall structure.

[0037] In some embodiments, the mounting base 300 includes a connecting block 340, a connecting hole 320 is disposed on the connecting block 340, one side of the connecting block 340 is connected to a fixing block 330, the upper surface of the fixing block 330 is higher than the upper surface of the connecting block 340, and the lower surface of the fixing block 330 is higher than the lower surface of the connecting block 340, thereby adapting to the positional characteristics of the lower end of the trigger 410 and the lower end of the handle 420 of the manual spray gun 400. The upper side of the fixing block 330 is designed to be higher than the upper side of the connecting block 340, which facilitates the manual spray gun 400 to be installed in the rotary spraying mechanism. At the same time, the lower side of the fixing block 330 is designed to be higher than the lower side of the connecting block 340, which can reduce the weight and space occupied by the mounting base 300, and facilitate the installation of industrial robots.

[0038] In some specific embodiments, see Figure 1 and Figure 3 The connecting block 340 has a mounting hole 350 for connecting an industrial robot on the side away from the fixing block 330. Specifically, the mounting base 300 is fixedly connected to the end of the robotic arm of the industrial robot by screws and mounting holes 350, so that the rotary spraying mechanism is installed on the industrial robot. At the same time, the manual spray gun 400 is inserted into the connecting hole 320, so that the manual spray gun 400 is fixed on the mounting base 300. The drive line of the driver 100 is connected to the control system of the industrial robot, so that the industrial robot can move the manual spray gun 400 and adjust the spraying amount of the manual spray gun 400 through the driver 100.

[0039] In some embodiments, see Figure 2 and Figure 4The helical cam 200 has a cylindrical portion 210 and a protrusion 220. The protrusion 220 is disposed on the outer periphery of the cylindrical portion 210 and covers a portion of the side surface of the cylindrical portion 210. The width of the protrusion 220 gradually decreases in the direction away from the cylindrical portion 210. The output shaft of the driver 100 is fixed on the centerline of the cylindrical portion 210. The highest point of the helical cam 200 is disposed at the tip of the protrusion 220 away from the cylindrical portion 210, and the lowest point of the helical cam 200 is disposed on the exposed side surface of the cylindrical portion 210. The arcuate side surface between the highest and lowest points is composed of the cylindrical portion 210 and the protrusion 220, and extends in the direction away from the cylindrical portion 210 from the arcuate side surface of the protrusion 220. For example, see... Figure 1 When the helical cam 200 is in its initial position, the side of the cylindrical portion 210 is in contact with the trigger 410. When the helical cam 200 is rotated counterclockwise, the trigger 410 leaves the side of the cylindrical portion 210 and contacts the side of the protrusion 220. As the curvature of the side of the protrusion 220 changes, the helical cam 200 continuously increases the downward pressure depth on the trigger 410. When it reaches the highest point of the tip of the protrusion 220, the spray volume of the manual spray gun 400 reaches a controllable maximum value. If the helical cam 200 is rotated counterclockwise at this point, the trigger 410 leaves the protrusion 220 and re-engages with the cylindrical portion 210, and the manual spray gun 400 stops spraying. It is understood that the helical cam 200 of this invention can be a helical cam of the prior art.

[0040] This is illustrated with a specific embodiment. First, the helical cam 200 is rotated to its initial position by the driver 100, and the handle 420 of the manual spray gun 400 is inserted into the connection hole 320 of the mounting base 300. At this point, the trigger 410 is just in contact with the lowest point of the helical cam 200, but no pressure is generated between them. According to the operation command received from the industrial robot, the driver 100 drives the helical cam 200 to rotate to press the trigger 410. The industrial robot moves the manual spray gun 400 to perform the spraying operation. At the same time, the industrial robot can know and adjust the depth of the trigger 410 press based on the feedback from the driver 100, so that the control system can adjust the spraying volume of the manual spray gun 400. This allows the manual spray gun 400 to use the automatic spray head of the industrial robot, replacing the more expensive automatic spray gun.
