Description

Technical Field

[0001] This utility model relates to a linear 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 the appearance of products but also their weather resistance, corrosion resistance, and UV resistance. Coating processes in manufacturing are mainly divided into automated spraying using industrial robots and traditional manual spraying.

[0003] Industrial robot automated spraying employs advanced spraying technology and a precise control system, ensuring uniform coating thickness, eliminating missed areas, and providing stable and reliable coating quality. Furthermore, industrial robot spraying enables automated and continuous production, significantly improving efficiency and shortening production cycles. It can also be programmed to meet the spraying needs of different products, offering strong adaptability and high flexibility. Automated industrial robot spraying also reduces worker exposure to harmful coatings, lowering occupational disease risks, making operation safer, and minimizing accidents caused by human error. Traditional manual spraying is manually operated, requiring operators to hold spray guns. This method is not only time-consuming and labor-intensive but also makes it difficult to guarantee coating quality and uniformity, posing safety hazards and emission issues. With the continuous development of science and technology, automated robot spraying is gradually replacing manual spraying, becoming an important means of modern industrial intelligence.

[0004] 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 by a control cabinet. They are generally suitable for automated coating lines or robotic arms. Therefore, commercially available automatic spray guns are relatively more expensive than manual spray guns and require components such as proportional valves to control paint flow, resulting in higher costs. Handheld spray guns, on the other hand, require constant human operation. Because they require manual control of the trigger's pressure, their application in industrial robot automated spraying is more difficult. Utility Model Content

[0033] Reference Figures 1 to 4 In some embodiments, the linear spraying mechanism and industrial robot of the manual spray gun according to the present invention include a linear displacement device 100 for receiving instructions from the industrial robot and a pressing block 200. The linear displacement device 100 includes a movable slider 120; the pressing block 200 is fixed on the slider 120 to press or release the trigger 410 of the manual spray gun 400. Specifically, when the linear displacement device receives a spraying instruction from the industrial robot, it drives the pressing block 200 to move, so that the pressing block 200 presses down the trigger 410 of the manual spray gun 400 to achieve spraying. After the spraying is completed, the linear displacement device drives the pressing block 200 to move in the opposite direction, so that the pressing block 200 releases the trigger 410 of the manual spray gun 400 to stop the spraying. Furthermore, the spraying amount of the manual spray gun 400 can be adjusted by adjusting the depth of the pressing block 200 pressing down the trigger.

[0034] 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 adjust the pressing depth. This allows the manual spray gun 400 to be applied to industrial robot automatic spraying equipment, thus replacing the automatic spray gun in some applications and effectively reducing usage costs.

[0035] In some embodiments, the linear displacement device 100 is provided with a driver 130 for providing pressing power. The drive circuit of the driver 130 can be connected to the control system of the industrial painting robot. Through the PLC linkage control of the industrial painting robot, the industrial robot can adjust the pressing degree of the trigger 410, thereby realizing the automatic adjustment of the spraying amount. It is understood that the linear displacement device 100 of this utility model can be a standard linear displacement device 100. Furthermore, a standard linear displacement device 100 with a suitable stroke and bearing torque can be selected to reduce costs while meeting the working conditions.

[0036] In some embodiments, see Figures 1 to 3 The linear displacement device 100 also includes a support platform, a slider 120, and a driver 130. A pressing block 200 is fixed to the slider 120, which is movably mounted on the support platform. The driver 130 is fixed to one side of the support platform and connected to the slider 120, thereby moving the slider 120 and the pressing block 200 to press down or release the trigger 410 of the manual spray gun 400, thus adjusting the spray volume. Specifically, the support platform has a U-shaped structure, including a horizontal support plate 111 and two vertical support plates 112. The two vertical support plates 112 are respectively located on opposite sides of the horizontal support plate 111. The driver 130 is connected to the side of one of the vertical support plates 112 facing away from the horizontal support plate 111. The slider 120 is located between the two vertical support plates 112 and is movably mounted on the horizontal support plate 111. The central shaft of the driver 130 passes through the slider 120 to move the slider 120. Furthermore, a slide rail is provided between the lower side of the slider 120 and the upper side of the cross plate 111. In a specific embodiment, the driver 130 may be a rotary driver 130, such as a rotary motor, a rotary servo motor, a rotary cylinder, etc., and the central shaft of the driver 130 is threadedly connected to the slider 120.

[0037] In some embodiments, the pressing block 200 is fixed to the slider 120 of the support platform and, driven by the driver 130, moves linearly along the cross plate 111 to move away from or towards the trigger 410 of the manual spray gun 400. Specifically, the pressing block 200 has an L-shaped structure and includes a connecting plate 210 and a boss 220. See [link to documentation]. Figure 1 and Figure 2 A boss 220 is located on the left rear side of the connecting plate 210. One side of the connecting plate 210 is connected to one side of the boss 220. The connecting plate 210 is fixed to the slider 120. The boss 220 protrudes from the linear displacement device 100. One side of the boss 220 can abut against the trigger 410, thereby pressing the trigger 410 of the manual spray gun 400 through the boss 220. Furthermore, the pressing block 200 is fixed to the upper side of the slider 120 by screws.

[0038] In some embodiments, the linear spraying mechanism of the manual spray gun and the industrial robot further include a mounting base 300, on which the linear displacement device 100 is fixed. Further, the mounting base 300 is provided with a mounting hole 310 allowing the handle 420 of the manual spray gun 400 to pass through. Specifically, the mounting base 300 includes a fixing plate 330 and a mounting plate 320, the mounting hole 310 is provided on the mounting plate 320, and the positions of the fixing plate 330 and the mounting plate 320 are determined according to the positions of the trigger 410 and the handle 420 of the manual spray gun 400. Further, one corner of the fixing plate 330 and one corner of the mounting plate 320 are connected, see [reference needed]. Figure 1 and Figure 4 The fixed plate 330 is connected to the mounting plate 320 and is located on the right rear side of the mounting plate 320. The cross plate 111 of the support platform is fixed to the fixed plate 330. At this time, the driver 130 is in front of the fixed plate 330. When the trigger 410 of the manual spray gun 400 is oriented towards the left side of the handle 420, the handle 420 can pass through the mounting hole 310, and the trigger 410 is positioned on the right side of the pressing block 200. It can be understood that the linear displacement device 100 is fixed to one side of the mounting base 300, and the other side of the mounting base 300 is fixed to the operating end of the industrial robot, so that the industrial robot can drive the manual spray gun 400 and its linear spraying mechanism to move.

[0039] Furthermore, the size of the mounting plate 320 can be set according to the size of the cross-plate 111. For example, if the size of the cross-plate 111 is designed to be similar to the size of the mounting plate 320, interference with the industrial robot can be effectively reduced. Furthermore, the size of the mounting hole 310 is adapted to the size of the handle 420, allowing the manual spray gun 400 to be locked in the mounting hole 310, thereby fixing the manual spray gun 400 to the linear displacement device 100 through the mounting hole 310.

[0040] This is illustrated with a specific embodiment. First, the pressing block 200 on the linear displacement device 100 is moved to its initial position, and the handle 420 of the manual spray gun 400 is inserted into the mounting hole 310 of the mounting base 300. At this time, the trigger 410 is just in contact with the pressing block 200, but no pressure is generated between them. According to the operation command received from the industrial robot, the driver 130 drives the pressing block 200 to move towards the trigger 410 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 130, 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.
