Description

Technical Field

[0001] This utility model belongs to the field of spray painting technology, specifically relating to an automatic spray painting device. Background Technology

[0002] Currently, spray painting is widely used in industries such as machinery manufacturing, automotive parts, furniture decoration, and metal products. Traditional spray painting processes mostly involve manual hand-held spray guns to coat the workpiece surface. Although this method requires less equipment investment, operators need to be in the spray painting environment for extended periods, which is not only physically demanding but also exposes them to paint fumes, affecting their health. Furthermore, manual spray painting is greatly affected by human factors such as operating techniques, angles, and distances, leading to uneven paint layer thickness, insufficient coverage, or runs, making it difficult to guarantee paint stability and consistency.

[0003] To improve painting quality and efficiency, some companies have begun using semi-automatic or fully automatic painting equipment. This type of equipment typically uses a set trajectory or robotic arm movement to automatically spray paint onto the workpiece surface. However, existing automatic painting equipment still has certain shortcomings in its structural design. For example, some equipment uses a single method for fixing the workpiece support structure, making it difficult to adapt to parts of different specifications, leading to unstable positioning or cumbersome installation; the limited range of motion of the spray gun during painting prevents comprehensive multi-angle and multi-directional spraying of the workpiece, creating painting dead zones; furthermore, the paint mist generated during painting operations has a large diffusion range, and if the equipment lacks effective suction and protective mechanisms, it will not only reduce paint utilization but also pollute the operating environment.

[0004] Meanwhile, the loading and unloading processes of existing automatic painting equipment are often carried out separately from the painting operation, requiring waiting for the painting to be completed before unloading or unloading materials, which prolongs the production cycle and affects work efficiency. Some equipment lacks coordinated control during the switching between painting and material changeover, which may lead to mechanical interference or contamination of the painting area, affecting the coating quality. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide an automatic painting equipment that can realize multi-directional spraying and has a suction protection function, so as to solve the above problems and improve the painting quality and production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic painting device includes a support base plate, a fixed column is provided on one side of the top surface of the support base plate, and a column is fixed on the other side of the top surface of the support base plate. A lead screw is vertically rotatably installed on the front side of the fixed column, and a lifting block is slidably installed on the front side of the fixed column. The lifting block is screwed onto the surface of the lead screw, and a telescopic beam is slidably installed on the upper surface of the lifting block.

[0008] A rotating seat is installed at the end of the telescopic beam. The rotating seat is controlled by a motor, and a spray gun is fixed on the surface of the rotating seat.

[0009] A support base is fixed to the rear side of the support base plate, a material plate is rotatably mounted on the top of the support base plate, and a suction mechanism is fixedly mounted on the upper surface of the support base plate.

[0010] An isolation mechanism is installed on the surface of the column.

[0011] Furthermore, the lead screw is controlled by a motor, and corrugated anti-slip covers are connected to both the upper and lower parts of the lifting block. The corrugated anti-slip covers wrap around the outside of the lead screw, and the ends of the two corrugated anti-slip covers opposite to the lifting block are respectively connected to the upper and lower inner walls of the fixed column.

[0012] Furthermore, the support base has a built-in motor, the material plate is installed at the output end of the motor, and a drive motor is provided below both ends of the material plate. A rotating shaft is installed at the output end of the drive motor, and the rotating shaft passes through the material plate.

[0013] Furthermore, four support arms are evenly arranged on the top of the rotating shaft, and T-shaped grooves are formed on the surface of the support arms. Limiting blocks are slidably installed inside the T-shaped grooves, and multiple limiting blocks are fixed by bolts to limit the position of the parts to be painted.

[0014] The front end of the material plate corresponds to the position of the spray gun, and the front end of the material plate is positioned directly above the suction mechanism.

[0015] Furthermore, the suction mechanism includes a suction cone fixed to the surface of the support base plate, and the suction cone has a structure that is larger at the top and smaller at the bottom.

[0016] Furthermore, a fan is connected to one end of the bottom of the suction cone, and a grille is installed at the open top of the suction cone.

[0017] Furthermore, the isolation mechanism includes an arc-shaped protective plate, which is placed above the suction mechanism on the side opposite to the spray gun. Two connecting plates are welded to the back of the arc-shaped protective plate, and each of the two connecting plates has a tie rod hinged to its surface.

[0018] Furthermore, the ends of the two pull rods facing away from the connecting plate are respectively hinged to the surface of the column, and a telescopic cylinder is hinged to the top of the column, with the output shaft of the telescopic cylinder hinged to the connecting plate above.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This automatic painting equipment, through the coordinated arrangement of a support base plate, fixed column, upright column, lead screw, lifting block, telescopic beam, and rotating seat, enables the spray gun to achieve multi-degree-of-freedom movement in the up-down, forward-backward, and rotational directions. This allows for flexible adjustment of the spraying trajectory according to the shape and structure of different parts and the required painting angle. The angle of the spray gun can be controlled by the rotating seat, the telescopic beam can move laterally, and the lead screw drives the lifting block to complete the height adjustment. This allows the spray gun to comprehensively paint the upper surface, sides, and slopes of the parts during the painting process, avoiding the defects of traditional manual painting, such as single angle and uneven coverage, and improving the uniformity and adhesion of the paint.

[0021] This automatic painting equipment features a linkage structure on the material plate consisting of a drive motor, rotating shaft, support arm, and limit block. The sliding engagement of the T-shaped groove and the limit block allows for the rapid clamping and fixing of parts of different sizes, ensuring stability during painting and enhancing the equipment's adaptability to various parts specifications. Driven by the motor, the material plate can rotate 180 degrees, automatically flipping to the other side after painting one side, enabling simultaneous painting and material loading / unloading. This effectively reduces standby time, improves production cycle time and equipment utilization, and solves the problem of low efficiency caused by separate loading / unloading and painting processes in existing painting equipment.

[0022] This automatic spray painting equipment achieves efficient absorption and filtration of excess paint mist during the spraying process through a combination of a suction cone, a fan, and a grille. The converging structure of the suction cone guides the paint mist into a negative pressure area, while the fan provides stable suction to draw the paint mist in and transport it to a centralized processing system. The grille prevents large particles from falling into the system. This structure effectively reduces paint mist diffusion during the spraying process, prevents environmental pollution and paint dust accumulation, improves air quality in the spraying area, and solves the problems of incomplete paint mist treatment and serious environmental pollution in traditional spray painting equipment.

[0023] The automatic painting equipment features an isolation mechanism comprising an arc-shaped protective plate, a connecting plate, a pull rod, and a telescopic cylinder. The telescopic cylinder drives the arc-shaped protective plate via the pull rod to form an adjustable double-link mechanism, allowing dynamic adjustment of the protective plate's position according to the size of the workpiece being painted. During painting, the protective plate is positioned close to the painting area, effectively blocking the outward spread of paint mist from the side opposite the spray gun, while maintaining a perpendicularity to the spray direction, concentrating the paint mist within the suction cone's intake area. This structural combination reduces paint diffusion pollution and improves paint mist collection efficiency, solving the problems of insufficient paint protection and significant environmental pollution associated with existing equipment.

[0031] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0032] refer to Figures 1 to 5As shown, an automatic spray painting device includes a supporting base plate 1. A fixed column 2 is provided on one side of the top surface of the supporting base plate 1, and a column 12 is fixed on the other side of the upper surface of the supporting base plate 1. A lead screw 21 is vertically rotatably mounted on the front side of the fixed column 2, and a lifting block 22 is slidably mounted on the front side of the fixed column 2. The lifting block 22 is screwed onto the surface of the lead screw 21, and a telescopic beam 3 is laterally slidably mounted on the upper surface of the lifting block 22. A rotating seat 31 is installed at the end of the telescopic beam 3. The rotating seat 31 is controlled by a motor, and a spray gun 4 is fixed on the surface of the rotating seat 31. A supporting base 11 is fixed on the rear side of the supporting base plate 1. A material plate 5 is rotatably mounted on the top of the supporting base 11, and a suction mechanism 6 is fixedly mounted on the upper surface of the supporting base plate 1. A partition is installed on the surface of the column 12. The mechanism 7 is separated from the fixed column 2, the upright column 12 and the support base 11 to form a stable spatial support frame. The support base plate 1 is used to support all working parts and maintain overall balance. The lead screw 21 rotates under the drive of the motor to drive the lifting block 22 to move up and down along the fixed column 2, thereby driving the telescopic beam 3 to complete the height adjustment. The telescopic beam 3 can realize the front and back displacement under the action of the transverse guide rail, so that the spray gun 4 can cover different areas of the parts to be painted. The rotating base 31 is driven by the motor to adjust the angle, which enables the spray gun 4 to achieve multi-angle spraying operation. This structure enables the spray gun 4 to spray parts of different sizes, shapes and installation positions in all directions, overcoming the problems of spray dead angle and limited angle of existing painting equipment.

[0033] refer to Figure 2 and Figure 3 As shown, the lead screw 21 is controlled by a motor, and the lifting block 22 is connected to both the upper and lower parts by corrugated anti-slip covers 23. The corrugated anti-slip covers 23 wrap around the outside of the lead screw 21, and the ends of the two corrugated anti-slip covers 23 facing away from the lifting block 22 are respectively connected to the upper and lower inner walls of the fixed column 2. The corrugated anti-slip covers 23 are made of oil-resistant and dust-proof rubber material, which is used to prevent paint mist, dust or debris from entering the transmission area between the lead screw 21 and the lifting block 22 during the painting process. The lead screw 21 adopts a high-precision thread structure, which can stably drive the lifting block 22 to move in the vertical direction under the control of the motor, avoiding shaking and errors during the lifting process. The sliding surface of the lifting block 22 is embedded with a linear bearing, which can improve the smoothness of lifting and reduce mechanical wear, thereby ensuring the accurate position of the spray gun 4 when spraying in the vertical direction. Through this structure, the height of the spray gun can be flexibly adjusted, ensuring the uniformity and coverage of the spraying of parts at different heights, and improving the painting quality.

[0034] refer to Figure 3 and Figure 4As shown, the support base 11 has a built-in motor, and the material plate 5 is installed at the output end of the motor. Drive motors 51 are installed below both ends of the material plate 5, and rotating shafts 52 are installed at the output ends of the drive motors 51, passing through the material plate 5. The drive motors 51 are electrically connected to the main control system and can automatically control the rotation speed and direction of the rotating shafts 52 according to the painting program. The rotating shafts 52 are made of high-strength alloy steel and are used to drive the support arm 53 to rotate, thereby causing the parts mounted on the support arm 53 to rotate synchronously. The upper surface of the material plate 5 has evenly distributed mounting holes for fixing workpiece support mechanisms of different specifications. The material plate 5 is driven by the motor inside the support base 11 to achieve a 180-degree rotation, allowing the workpiece to be painted to be rotated from the loading area to the painting area, and then rotated back to the loading area after painting, achieving synchronous loading, unloading, and painting. This structure solves the problem of low efficiency caused by separate painting and material handling in existing equipment.

[0035] refer to Figure 3 and Figure 4 As shown, four support arms 53 are evenly arranged on the top of the rotating shaft 52. T-shaped grooves 54 are formed on the surface of the support arms 53. Limiting blocks 55 are slidably installed inside the T-shaped grooves 54. Multiple limiting blocks 55 are fixed with bolts to limit the position of the parts to be painted. The front end of the material plate 5 corresponds to the position of the spray gun 4 and is positioned directly above the suction mechanism 6. The support arms 53 are arranged symmetrically to maintain the balance of the material plate 5 when rotating. The position of the limiting blocks 55 can be adjusted in the radial direction according to the size of the parts. The T-shaped grooves 54 and the limiting blocks 55 cooperate to achieve tight limiting and fixing of parts of different specifications. Each limiting block 55 is provided with a rubber anti-slip pad to avoid indentation or slippage on the surface of the parts during the fixing process. The material plate 5 and the spray gun 4 are kept at the optimal spraying distance, so that the paint mist is evenly distributed during the spraying process and the spraying coverage is improved. The adjustable structure of the limiting blocks 55 effectively solves the problems of single part fixing method and inaccurate positioning in existing equipment.

[0036] refer to Figure 3 and Figure 4 As shown, the suction mechanism 6 includes a suction cone 61 fixed to the surface of the support base plate 1. The suction cone 61 has a structure that is larger at the top and smaller at the bottom. A fan 62 is connected to one end of the bottom of the suction cone 61, and a grille 63 is installed at the open top of the suction cone 61. The suction cone 61 is made of welded metal plate, and the inner wall is treated with anti-corrosion spraying, which can withstand the corrosion of paint mist in the painting environment for a long time. The fan 62 is installed at the bottom of the cone and connected to the exhaust duct. It is used to generate negative pressure suction during the painting process to quickly suck the paint mist generated during the painting process into the cone. The grille 63 is made of stainless steel wire mesh, which can prevent workpiece debris or foreign objects from falling into the suction system, while maintaining a stable airflow channel. This suction mechanism 6 can effectively reduce the diffusion of paint mist during the painting operation, reduce environmental pollution, ensure the cleanliness of the air in the painting area, and improve the painting accuracy.

[0037] refer to Figure 1 , Figure 2 and Figure 5 As shown, the isolation mechanism 7 includes an arc-shaped protective plate 71, which is positioned above the suction mechanism 6 on the side opposite to the spray gun 4. Two connecting plates 72 are welded to the back of the arc-shaped protective plate 71, and each connecting plate 72 has a pull rod 73 hinged to its surface. The ends of the two pull rods 73 opposite to the connecting plates 72 are respectively hinged to the surface of the column 12. A telescopic cylinder 74 is hinged to the top of the column 12, and the output shaft of the telescopic cylinder 74 is hinged to the upper connecting plate 72. During the painting process, the telescopic cylinder 74 is driven by the control system, causing the pull rods 73 to form a double-link structure, thereby controlling the approach and departure of the arc-shaped protective plate 71. The plate 71 is made of high-temperature resistant and corrosion-resistant material. Its curved surface is perpendicular to the spray direction of the spray gun 4, which is used to block excess paint mist from spreading outward during the painting process. Through the hinged cooperation of two pull rods 73, the curved protective plate 71 always maintains a vertical posture during the movement, avoiding deviation of the protection angle. The movement of the telescopic cylinder 74 is synchronized with the painting program and can automatically adjust the position of the curved protective plate 71 according to the size of the workpiece. This isolation mechanism 7 can effectively block the spread of paint mist and prevent the painting from polluting the surrounding environment. At the same time, a top cover can be optionally installed on the top of the curved protective plate 71 to further enhance the sealing and protection effect and ensure a clean and stable painting environment.

[0038] The working principle of this utility model is as follows: the part to be painted is placed on the surface of the four support arms 53, and the limiting block 55 is pushed to move along the T-shaped slide 54 towards the center. After being fixed by bolts, the part to be painted is limited. The material plate 5 is rotated 180 degrees at a time by the motor to rotate the installed part above the suction mechanism 6. The lifting block 22 is moved up and down by the rotation of the lead screw 21. The telescopic beam 3 can be moved forward and backward laterally by the motor to drive the spray gun 4 to move in multiple directions. The rotation of the rotating seat 31 can adjust the spraying angle of the spray gun 4. The drive motor 51 is started to control the rotation of the part to be painted, thereby realizing automatic painting work in multiple angles and directions.

[0039] During painting, the blower 62 is activated to draw in excess mist through the suction cone 61 for centralized treatment. The grid 63 on the upper surface of the suction cone 61 can prevent materials from falling into the suction cone 61 without affecting the suction. During painting, the telescopic cylinder 74 is activated to control the angle of the pull rod 73. The two pull rods 73 can control the movement of the arc-shaped protective plate 71, so that the arc-shaped protective plate 71 moves closer to the painting area. The two pull rods 73 are combined to form a double linkage mechanism, which can keep the axis of the arc-shaped protective plate 71 vertical during the adjustment process. The arc-shaped protective plate 71 is placed on the side of the part away from the spray gun 4, which can block excess mist from the paint spray and reduce the pollution of the surrounding environment caused by the mist diffusion. A top cover can also be added to the top of the arc-shaped protective plate 7 according to the size of the part.

[0040] During the painting process, the other end of the material plate 5 is loaded and unloaded. After a single painting is completed, the arc-shaped protective plate 71 is first controlled to move outward and get out of the rotation area of ​​the material plate 5. Then it is rotated 180 degrees to paint another part. This structure can realize the synchronous loading and unloading and painting, thereby improving production efficiency.

[0041] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
