Description

Technical Field

[0001] This utility model relates to the field of stair painting technology, specifically a painting device for stair production. Background Technology

[0002] In the staircase manufacturing industry, spray painting is a crucial step in improving the appearance quality, corrosion resistance, and lifespan of staircases. Traditional staircase spray painting mainly relies on manual operation, with workers using handheld spray guns to coat various parts of the staircase. Manual spray painting is inefficient. Due to the complex structure of staircases, which include components of different shapes and positions such as treads, risers, and handrails, workers need to constantly adjust their position and spray gun angle to complete the overall coating. This process is time-consuming and cannot meet the demands of high-efficiency production for large-scale staircase manufacturing. Furthermore, the quality of manual spray painting is difficult to guarantee. Differences in worker skills and experience lead to uneven coating, such as excessively thick paint causing runs in some areas, while insufficient paint in others fails to achieve the desired protective and decorative effects. Moreover, manual operation makes it difficult to precisely control the spraying area, easily causing paint mist to spread into the surrounding environment, resulting in paint waste, harm to worker health, and compliance with environmental protection requirements. Therefore, a spray painting device for staircase production has been proposed to address these problems. Utility Model Content

[0003] (a) Technical problems to be solved The purpose of this invention is to solve the problems of low efficiency and difficulty in guaranteeing the quality of manual spray painting, and to propose a spray painting device for staircase production.

[0004] (II) Technical Solution The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A painting device for stair production includes a workbench, a vertical moving mechanism rotatably connected to the top of the workbench, a horizontal moving mechanism provided at the front end of the vertical moving mechanism, a spraying device fixedly connected to the front end of the horizontal moving mechanism, and a drive mechanism for driving the vertical moving mechanism to rotate provided on the inner side of the workbench.

[0005] Based on the above technical solution, the present invention can be further improved as follows.

[0006] Preferably, the vertical moving mechanism includes a vertical seat, which is rotatably connected to the top of the worktable. A first motor is fixedly connected to the vertical seat, and a lead screw is fixedly connected to the output end of the first motor. Two rotating seats are fixedly connected to the front end of the vertical seat, and the lead screw is rotatably connected to the inner side of the two rotating seats. A threaded sleeve is threadedly connected to the outer side of the lead screw, and the threaded sleeve is fixedly connected to the rear end of the left and right moving mechanism. Two slide rails are fixedly connected to the front end of the vertical seat, and two sliders are slidably connected to the outer side of each of the two slide rails. The four sliders are fixedly connected to the rear end of the left and right moving mechanism.

[0007] Preferably, the left and right moving mechanism is a linear module, which is fixedly connected to the front end of the lead screw and the front end of the four sliders. The spraying device is fixedly connected to the moving end of the linear module.

[0008] Preferably, the driving mechanism includes a mounting base, the inner side of the worktable is fixedly connected to the mounting base, a second motor is fixedly connected to the mounting base, the bottom end of the vertical seat is fixedly connected to a rotating shaft, the rotating shaft is rotatably connected to the inner side of the worktable, and the rotating shaft and the second motor are connected through a transmission mechanism.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] In the embodiments, by Figure 1-3 A painting device for stair production is provided, comprising a workbench 1, a vertical moving mechanism 2 rotatably connected to the top of the workbench 1, a horizontal moving mechanism 3 provided at the front end of the vertical moving mechanism 2, a spraying device 4 fixedly connected to the front end of the horizontal moving mechanism 3, and a drive mechanism 5 for driving the vertical moving mechanism 2 to rotate provided on the inner side of the workbench 1.

[0014] With the above setup, the operator secures the stair component to be painted (e.g., a step or a section of handrail). The drive mechanism 5 starts working, causing the entire up-and-down moving mechanism 2 to rotate at the top of the worktable 1. This rotation may be to adjust the initial angle of the spraying device 4 relative to the workpiece, or for spraying curved stair components (such as the side beams of a spiral staircase). The up-and-down moving mechanism 2 itself moves up and down, moving the entire front-end assembly along the height of the workpiece. The left-and-right moving mechanism 3, driven by the up-and-down moving mechanism 2, performs a horizontal reciprocating motion. Through the combination of the rotation of the drive mechanism 5, the lifting and lowering of the up-and-down moving mechanism 2, and the translation of the left-and-right moving mechanism 3, the spray gun of the spraying device 4 can form a complex motion trajectory covering the entire surface of the workpiece. The spraying device 4 (which can be any device capable of spraying known to those skilled in the art, such as a spray gun) continuously and evenly sprays paint during its movement. When the painting of one workpiece is completed, all moving mechanisms stop, and the spraying device 4 shuts down. The device automatically returns to its initial position, ready to paint the next workpiece. Operators remove painted workpieces, replace them with new workpieces to be painted, and begin the next cycle. This enables continuous, batch operations, with a painting cycle time significantly shorter than manual painting. Operators only need to load and unload materials, resulting in low labor intensity, a substantial increase in production efficiency, and a solution to the problem of inconsistent quality in manual painting.

[0015] Reference Figure 1-3The vertical moving mechanism 2 includes a vertical seat 21, which is rotatably connected to the top of the worktable 1. A first motor 22 is fixedly connected to the vertical seat 21, and a lead screw 23 is fixedly connected to the output end of the first motor 22. Two rotating seats 24 are fixedly connected to the front end of the vertical seat 21. The lead screw 23 is rotatably connected to the inner side of the two rotating seats 24. A threaded sleeve 25 is threadedly connected to the outer side of the lead screw 23. The threaded sleeve 25 is fixedly connected to the rear end of the left and right moving mechanism 3. Two slide rails 26 are fixedly connected to the front end of the vertical seat 21. Two sliders 27 are slidably connected to the outer side of each of the two slide rails 26. The four sliders 27 are fixedly connected to the rear end of the left and right moving mechanism 3. With the above structural configuration, when the system needs to move up and down, the first motor 22 is activated. The rotational motion of the first motor 22 is transmitted to the lead screw 23, which is fixedly connected to it, causing the lead screw 23 to rotate forward or backward. The rotating lead screw 23 engages with the threaded sleeve 25. Since the threaded sleeve 25 is fixed to the rear end of the left and right moving mechanism 3, and the left and right moving mechanism 3 is constrained to the slide rail 26 by the sliders 27, the threaded sleeve 25 itself cannot rotate. Therefore, the rotational motion of the lead screw 23 is converted into precise linear motion of the threaded sleeve 25 (i.e., the entire left and right moving mechanism 3) along the axis of the lead screw 23. While the threaded sleeve 25 drives the left and right moving mechanism 3 to move up and down, the four sliders 27 fixed to the rear end of the mechanism slide along the two vertical slide rails 26. This ensures that the entire left and right moving mechanism 3 moves strictly in the vertical direction without any back-and-forth or left-and-right swaying. It also bears the weight of the left and right moving mechanism 3 and the spraying device 4 itself, as well as the torque and load generated by the movement, preventing the lead screw 23 from bearing radial force, ensuring smooth and precise movement, and extending the life of the lead screw 23.

[0016] Reference Figure 1-3 Among them, the left and right moving mechanism 3 is a linear module, which is fixedly connected to the front end of the lead screw 23 and the front end of the four sliders 27. The spraying device 4 is fixedly connected to the moving end of the linear module. With the above structural configuration, this left-right moving mechanism 3 is a linear module, a highly integrated standard linear motion unit. Its working principle is similar to the aforementioned up-down moving mechanism 2, but the direction of movement is horizontal.

[0017] Reference Figure 1-3 The drive mechanism 5 includes a mounting base 51. The mounting base 51 is fixedly connected to the inner side of the worktable 1. A second motor 52 is fixedly connected to the mounting base 51. A rotating shaft 53 is fixedly connected to the bottom end of the vertical seat 21. The rotating shaft 53 is rotatably connected to the inner side of the worktable 1. The rotating shaft 53 and the second motor 52 are connected through a transmission mechanism 54. With the above structural configuration, when the spraying angle needs to be adjusted (e.g., switching from spraying a vertical surface to an inclined surface), the second motor 52 (usually a servo motor or stepper motor) is activated. The rotational power of the second motor 52 is transmitted and adjusted through a transmission mechanism 54 (which can be a belt drive mechanism, sprocket and chain drive mechanism, etc.). The transmission mechanism 54 transmits power and motion to the rotating shaft 53, causing it to rotate. The bottom end of the rotating shaft 53 is rotatably connected to the inside of the worktable 1 through bearings or other components, ensuring that the rotating shaft 53 can rotate flexibly and smoothly while being positioned axially and radially. The bottom end of the vertical seat 21 is fixedly connected to the top end of the rotating shaft 53 (e.g., through a flange or keyway). Therefore, when the rotating shaft 53 rotates, it directly drives the entire vertical seat 21 to rotate around the axis of the rotating shaft 53. Since the vertical moving mechanism 2 (the entire vertical seat 21, lead screw 23, slide rail 26, etc.), the left and right moving mechanism 3 (linear module) and the spraying device 4 are all installed on the vertical seat 21, all these components rotate as a whole when the vertical seat 21 rotates.
