Description

Technical Field

[0001] This invention relates to the field of coating equipment technology, specifically to a fully automatic coating equipment for metal parts. Background Technology

[0002] In industrial production, surface coating of metal parts (such as spray paint, rust-preventive oil, lubricating grease, sealant, powder coating, and special functional coatings) is a crucial process. Its main purpose is to isolate the metal parts from moisture, oxygen, and corrosive media in the environment, extend their service life, provide aesthetically pleasing color, gloss, and texture, enhance the product's appearance, and provide specific properties such as wear resistance, conductivity, insulation, lubrication, sealing, and high-temperature resistance, as seen in anti-spatter coating before welding and lubricating grease coating before assembly.

[0003] Manual coating relies on worker skill, resulting in slow production speed and difficulty in meeting the needs of mass production. The coating thickness, uniformity, and coverage are greatly affected by human factors (fatigue, skill differences), which can easily lead to problems such as missed coating, sagging, orange peel, and uneven thickness, resulting in fluctuations in product yield. It is also difficult to maintain consistent coating quality for products from different batches or operated by different workers. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a fully automatic coating device for metal parts, comprising a base plate, a transmission roller fixedly connected to one side of the top of the base plate, a coating device fixedly connected to the top portion of the base plate located on one side of the transmission roller, and a protective cover fixedly connected to the top of the base plate located above the coating device.

[0005] The coating device includes a main support, a drive assembly fixedly connected to the top of the main support, a coating assembly fixedly connected to the side of the drive assembly, a cleaning assembly fixedly connected to the side of the drive assembly away from the coating assembly, and a support assembly fixedly connected to the side of the drive assembly located between the cleaning assemblies. The bottom of the main support is fixedly connected to the top of the equipment base plate. The main support supports the drive assembly, which drives the coating assembly, cleaning assembly, and support assembly to move synchronously, thereby fixing and clamping pipes of different sizes to facilitate coating. The coating assembly sprays material, and the self-rotation of the coating assembly reduces the existence of coating dead zones, thus facilitating complete coverage.

[0006] Preferably, the drive assembly includes a fixed base, a sliding base slidably connected to the side of the fixed base, a drive rack fixedly connected to the inner wall of the sliding base, a drive gear meshing at the top of the drive rack, a drive gear ring meshing on the side of the drive gear away from the drive rack, an electric gear meshing on the inner wall of the drive gear ring, a movable plate fixedly connected to the side of the sliding base, the electric gear fixedly connected to the fixed base via a bracket, the side of the movable plate contacting the side of the fixed base, and the bottom of the fixed base fixedly connected to the top of the main bracket. In advanced mechanical design, the design of drive assemblies has extremely high requirements to ensure their efficient and stable operation. The drive assembly we are discussing has an ingenious structure. The foundation of the drive assembly is the fixed base, which acts like a solid fortress, providing stable support for the entire assembly. A sliding base is cleverly designed on the side of the fixed base, giving the sliding base the ability to move flexibly, like a graceful dancer moving freely on a stage. The drive rack is firmly fixedly connected to the inner wall of the sliding base, acting like a diligent... The drive unit, acting as a messenger of power, carries the vital mission of transmitting power. Its top meshes with the drive gear. When the drive gear rotates, it precisely transmits power to the sliding base through close engagement with the drive rack, enabling it to move along a preset trajectory. The side of the drive gear away from the drive rack meshes with a drive gear ring, which acts as a central hub, further transmitting and converting power. Inside the drive gear ring, an electric gear meshes. This electric gear, the source of the entire power system, is electrically driven, acting like a heart that continuously infuses the entire component with vitality. A movable plate is fixedly connected to the side of the sliding base, moving with it. The electric gear is fixedly connected to the fixed base via a bracket, ensuring its stability during operation. The side of the movable plate contacts the side of the fixed base, providing guidance and ensuring smooth movement. The bottom of the fixed base is fixedly connected to the top of the main support, which bears the responsibility of connecting the entire drive assembly to other equipment or structures, enabling the drive assembly to play its proper role in the entire system and contributing to the efficient operation of the machinery.

[0007] Preferably, the coating assembly includes a first support, a feeding pipe that is passed through and fixedly connected to the side of the first support, a heating pipe that is fixedly connected to the side of the first support located on the side of the feeding pipe, an insulation pipe that is sleeved and fixedly connected to the side of the heating pipe, a second support that is fixedly connected to the end of the insulation pipe away from the first support, a spraying assembly that is fixedly connected to the end of the feeding pipe away from the first support, the bottom of the second support that is fixedly connected to the side of the sliding base, and the bottom of the first support that is fixedly connected to the side of the sliding base. In many stages of industrial production, coating is a crucial and delicate task, and the design quality of the coating assembly directly affects the coating effect. Preferably, the coating assembly we are focusing on has a unique and practical structure. The foundation of the coating assembly is the first support, which acts as the skeleton of the entire assembly, providing stable support and a mounting base for other components. A feeding pipe is passed through and fixedly connected to the side of the first support. The feeding pipe plays a vital role, acting like a blood vessel that continuously delivers the materials required for coating to the work area. A heating pipe is fixedly connected to the side of the first support located on the side of the feeding pipe. Next, the heating tube, a crucial component of the coating process, heats the coating material to achieve the appropriate temperature and fluidity, ensuring uniformity and quality. It acts like a lifeblood, allowing the material to perform its function effectively. To minimize heat loss, an insulation tube is fitted and fixedly connected to the side of the heating tube. This insulation tube acts like a warm coat, tightly encasing the heating tube and maximizing heat utilization, thus improving energy efficiency. A second support is fixedly connected to the end of the insulation tube furthest from the first support. The second support works in conjunction with the first support to maintain the stability of the entire coating assembly. A spraying component is fixedly connected to the end of the feeding tube furthest from the first support. Like a skilled painter, the spraying component precisely sprays the heated and transported coating material onto the target surface, completing the coating operation. The bottom of the second support is fixedly connected to the side of the sliding base, as is the bottom of the first support. This connection method allows the coating assembly to flexibly adjust its position as the sliding base moves, adapting to different coating needs and providing strong support for efficient and precise coating operations.

[0008] Preferably, the spraying assembly includes a connecting pipe, a rotating seat rotatably connected to the side of the connecting pipe, a spiral spray pipe connected to the side of the rotating seat, a discharge port on the side of the spiral spray pipe, and a connection between the side of the connecting pipe and the side of the feeding pipe. When the electric gear is activated, it drives a drive gear ring to rotate, which in turn drives the drive gear to rotate, which in turn moves a drive rack, which in turn moves the drive gear. The electric gear is fixed to the side of the fixed base, creating relative motion between the drive gear ring and the fixed base. This causes the drive rack to move a sliding base, which in turn moves a moving plate, thus achieving synchronous sliding of multiple sets of sliding bases. This allows the sides of the sliding bases to move closer to or further away from the sides of the pipe, enabling coating of pipes of different sizes.

[0009] Preferably, the cleaning component includes an inclined bracket, a spray pipe is connected through and fixedly connected to the side of the inclined bracket, a telescopic tube is connected to the bottom of the spray pipe, a spring is sleeved and slidably connected to the side of the telescopic tube, a third bracket is fixedly connected to the end of the telescopic tube away from the inclined bracket, a filter component is connected through and fixedly connected to the side of the third bracket, the bottom of the inclined bracket is fixedly connected to the side of the sliding base, and the bottom of the third bracket is fixedly connected to the side of the fixed base.

[0010] Preferably, the filter assembly includes an air inlet pipe, a fan motor mounting part is fixedly connected to the inner wall side of the air inlet pipe, a spiral blade is fixedly connected to the rotating part of the fan motor, an air filter element is fixedly connected to the side of the air inlet pipe, a collection groove is fixedly connected to the end of the side of the air inlet pipe near the air filter element, the side of the air inlet pipe passes through the side of the third bracket and communicates with the telescopic pipe, the raw material flows through the feeding pipe and moves through the connecting pipe into the interior of the rotating seat, and is sprayed out along the discharge port through the spiral spray pipe. During the process of the raw material being sprayed out of the discharge port, the recoil force of the raw material spraying out drives the rotating seat to rotate along the side of the connecting pipe, thereby achieving uniform coating at multiple angles. Compared with the traditional fixed coating method, the existence of dead corners is reduced, and when the hot melt material passes through the inner wall of the feeding pipe, the feeding pipe is heated by the heating pipe, so that the raw material is kept in a flowing state on the inner wall of the feeding pipe, thereby preventing cooling during the coating process, and the heat is reflected by the heat insulation pipe, thereby reducing heat diffusion and reducing heating time.

[0011] Preferably, the support assembly includes a support frame, a guide frame fixedly connected to the top of the support frame, and an arc-shaped roller rotatably connected to the top of the guide frame. The side of the support frame is fixedly connected to the side of the fixed base. When the fan motor is started, the fan motor drives the spiral blades to rotate, and the rotation of the spiral blades drives the air to flow. The air is filtered through the air filter, and dust and other impurities remain inside the air inlet pipe and are concentrated inside the collection tank, thereby collecting dust and other impurities and preventing dust from falling onto the side of the pipe during the coating process and causing coating quality problems. The cooperation of the telescopic tube and spring ensures that the tilted support remains in a tightened state when it is away from or close to the third support, thereby reducing the clutter of the equipment. The tilted design of the tilted support causes the air outlet of the spray pipe to point at a certain angle, thereby cleaning the surface before coating and blowing away dust to avoid dust from mixing with the coating material under the action of air. The pipe is guided along the side of the guide frame and moves along the arc-shaped roller. The arc-shaped side of the arc-shaped roller fixes and guides the pipe, thereby ensuring that the pipe is fixed in place and in the right position.

[0012] This invention provides a fully automated coating device for metal parts. It has the following advantages:

[0013] 1. The fully automatic coating device for metal parts is equipped with a main support, which supports the drive component. The drive component drives the coating component, cleaning component, and support component to move synchronously, thereby fixing and clamping pipes of different sizes to facilitate coating. The coating component sprays the material and reduces the existence of coating dead corners by rotating the coating component, thus facilitating complete coverage.

[0014] 2. The fully automatic coating device for this metal component is equipped with an electric gear. The electric gear drives the drive gear ring to rotate, which in turn drives the drive gear to rotate. The drive gear rotates and moves the drive rack, which in turn moves the drive gear. The electric gear is fixed to the side of the fixed base, thereby creating relative motion between the drive gear ring and the fixed base. This causes the drive rack to move the sliding base, which in turn moves the moving plate, thus achieving synchronous sliding of multiple sets of sliding bases. This allows the sides of the sliding bases to move closer to or further away from the sides of the pipe, thereby enabling coating of pipes of different sizes.

[0015] 3. The fully automatic coating device for this metal part is equipped with a feeding pipe. The raw material flows through the feeding pipe and moves through the connecting pipe into the interior of the rotating seat. It is then sprayed out through the spiral nozzle along the outlet. During the process of the raw material being sprayed out of the outlet, the recoil force of the sprayed raw material drives the rotating seat to rotate along the side of the connecting pipe, thereby achieving uniform coating from multiple angles. Compared with the traditional fixed coating method, this reduces the existence of dead corners. Furthermore, when the hot melt material passes through the inner wall of the feeding pipe, the feeding pipe is heated by the heating pipe, so that the raw material remains in a flowing state on the inner wall of the feeding pipe, thereby preventing cooling during the coating process. The heat is reflected by the heat insulation pipe, thereby reducing heat diffusion and reducing heating time.

[0016] 4. The fully automatic coating device for this metal component is equipped with a fan motor that drives the spiral blades to rotate. The rotation of the spiral blades causes air to flow. The air is filtered through an air filter, and dust and other impurities are retained inside the air inlet pipe and collected in the collection tank. This process collects dust and other impurities, preventing dust from falling onto the side of the pipe during coating and causing coating quality problems. The device uses a telescopic tube and spring to maintain a tightened state when the tilting bracket is away from or close to the third bracket, thus reducing the clutter of the equipment. The tilting design of the tilting bracket directs the air outlet of the spray pipe at a certain angle, thus cleaning the surface before coating. The tilting design also blows away dust, preventing direct airflow from mixing with the coating material. The pipe is guided along the side of the guide frame and moves along the arc-shaped rollers. The arc-shaped rollers fix and guide the pipe, ensuring that it is in place and in the correct position. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-2 The present invention provides a technical solution: a fully automatic coating device for metal parts, including a base plate 1, a transmission roller 2 fixedly connected to one side of the top of the base plate 1, a coating device 3 fixedly connected to the top of the base plate 1 located on one side of the transmission roller 2, and a protective cover 4 fixedly connected to the top of the base plate 1 located above the coating device 3.

[0028] The equipment base plate 1 supports the equipment, the transmission roller 2 guides the pipe, the coating device 3 coats the pipe, and the protective cover 4 protects the pipe to prevent external factors from affecting the coating quality. The cleaning and adjustment mechanism of the coating device 3 cleans and adjusts the pipe before coating, thereby ensuring the coating quality. The cleaning of the pipe body prevents dust and other influencing factors from affecting the coating quality. The support of the pipe allows for uniform coating from multiple angles, ensuring uniform coating.

[0029] The coating device 3 includes a main support 301, a drive assembly 302 fixedly connected to the top of the main support 301, a coating assembly 303 fixedly connected to the side of the drive assembly 302, a cleaning assembly 304 fixedly connected to the side of the drive assembly 302 away from the coating assembly 303, a support assembly 305 fixedly connected to the side of the drive assembly 302 located between the cleaning assembly 304, and the bottom of the main support 301 fixedly connected to the top of the equipment base plate 1.

[0030] The main support 301 supports the drive assembly 302, which drives the coating assembly 303, cleaning assembly 304, and support assembly 305 to move synchronously, thereby fixing and clamping pipes of different sizes to facilitate coating. The coating assembly 303 sprays the material and reduces the presence of coating dead corners by rotating the coating assembly 303, thus facilitating complete coverage.

[0031] Please see Figures 1-3 The present invention provides a technical solution: 302 includes a fixed base 3021, a sliding base 3022 slidably connected to the side of the fixed base 3021, a drive rack 3023 fixedly connected to the inner wall of the sliding base 3022, a drive gear 3024 meshing with the top of the drive rack 3023, a drive gear ring 3025 meshing with the side of the drive gear 3024 away from the drive rack 3023, an electric gear 3026 meshing with the inner wall of the drive gear ring 3025, a movable plate 3027 fixedly connected to the side of the sliding base 3022, the electric gear 3026 fixedly connected to the fixed base 3021 through a bracket, the side of the movable plate 3027 contacting the side of the fixed base 3021, and the bottom of the fixed base 3021 fixedly connected to the top of the main bracket 301.

[0032] The electric gear 3026 is activated, which drives the drive gear ring 3025 to rotate. The rotation of the drive gear ring 3025 drives the drive gear 3024 to rotate, and the rotation of the drive gear 3024 drives the drive rack 3023 to move. The movement of the drive rack 3023 drives the drive gear 3024 to move. The electric gear 3026 is fixed to the side of the fixed base 3021, thereby creating relative movement between the drive gear ring 3025 and the fixed base 3021. This causes the drive rack 3023 to drive the sliding base 3022 to move, and the movement of the sliding base 3022 drives the moving plate 3027 to move. This achieves synchronous sliding of multiple sets of sliding bases 3022, allowing the sides of the sliding bases 3022 to move closer to or further away from the sides of the pipe, thus enabling coating of pipes of different sizes.

[0033] Please see Figures 1-5The present invention provides a technical solution: the coating component 303 includes a first support 3031, a feeding pipe 3032 is fixedly connected through and fixedly connected to the side of the first support 3031, a heating pipe 3033 is fixedly connected to the side of the first support 3031 located on one side of the feeding pipe 3032, a heat insulation pipe 3034 is sleeved and fixedly connected to the side of the heating pipe 3033, a second support 3035 is fixedly connected to the end of the heat insulation pipe 3034 away from the first support 3031, a spraying component 3036 is fixedly connected to the end of the feeding pipe 3032 away from the first support 3031, the bottom of the second support 3035 is fixedly connected to the side of the sliding base 3022, and the bottom of the first support 3031 is fixedly connected to the side of the sliding base 3022.

[0034] The spraying assembly 3036 includes a connecting pipe 30361, a rotating seat 30362 rotatably connected to the side of the connecting pipe 30361, a spiral spray pipe 30363 connected to the side of the rotating seat 30362, a discharge port 30364 opened on the side of the spiral spray pipe 30363, and the side of the connecting pipe 30361 is connected to the side of the feeding pipe 3032.

[0035] The raw material flows through the feeding pipe 3032 and moves through the connecting pipe 30361 into the interior of the rotating seat 30362. It is then sprayed out through the spiral nozzle 30363 along the outlet 30364. During the process of the raw material being sprayed out through the outlet 30364, the recoil force of the sprayed raw material drives the rotating seat 30362 to rotate along the side of the connecting pipe 30361, thereby achieving uniform coating from multiple angles. Compared with the traditional fixed coating method, this reduces the existence of dead corners. Furthermore, when the hot melt material passes through the inner wall of the feeding pipe 3032, the heating pipe 3033 heats the feeding pipe 3032, thereby keeping the raw material in a flowing state on the inner wall of the feeding pipe 3032, thus preventing cooling during the coating process. The heat is reflected by the heat insulation pipe 3034, thereby reducing heat diffusion and reducing heating time.

[0036] Please see Figures 1-8 The present invention provides a technical solution: the cleaning component 304 includes an inclined bracket 3041, a spray pipe 3042 is connected through and fixedly connected to the side of the inclined bracket 3041, a telescopic tube 3043 is connected to the bottom of the spray pipe 3042, a spring 3044 is sleeved and slidably connected to the side of the telescopic tube 3043, a third bracket 3045 is fixedly connected to the end of the telescopic tube 3043 away from the inclined bracket 3041, a filter component 3046 is connected through and fixedly connected to the side of the third bracket 3045, the bottom of the inclined bracket 3041 is fixedly connected to the side of the sliding base 3022, and the bottom of the third bracket 3045 is fixedly connected to the side of the fixed base 3021.

[0037] The filter assembly 3046 includes an air inlet pipe 30461. A fixing part of a fan motor 30462 is fixedly connected to the inner wall side of the air inlet pipe 30461. A spiral blade 30463 is fixedly connected to the rotating part of the fan motor 30462. An air filter element 30464 is fixedly connected to the side of the air inlet pipe 30461. A collection groove 30465 is fixedly connected to the end of the side of the air inlet pipe 30461 near the air filter element 30464. The side of the air inlet pipe 30461 passes through the side of the third bracket 3045 and communicates with the telescopic pipe 3043.

[0038] The support assembly 305 includes a support frame 3051, a guide frame 3052 fixedly connected to the top of the support frame 3051, an arc-shaped roller 3053 rotatably connected to the top of the guide frame 3052, and the side of the support frame 3051 fixedly connected to the side of the fixed base 3021.

[0039] The fan motor 30462 is started, which drives the spiral blades 30463 to rotate. The rotation of the spiral blades 30463 causes air to flow. The air is filtered through the air filter element 30464, and dust and other impurities are retained inside the air intake pipe 30461 and collected inside the collection groove 30465. This collection of dust and other impurities prevents dust from falling onto the side of the pipe during the coating process and causing coating quality problems. The telescopic tube 3043 and the spring 3044 work together to allow the tilting bracket 3041 to move away from or near the third bracket 3045. When the bracket 3045 is in a tightened state, the clutter of the equipment is reduced. The tilted design of the inclined bracket 3041 causes the air outlet of the spray pipe 3042 to point at a certain angle, thereby cleaning the surface before coating. The tilted design also blows away dust, preventing dust from mixing with the coating material due to the airflow. The pipe is guided along the side of the guide bracket 3052 and moves along the arc-shaped roller 3053. The arc-shaped side of the arc-shaped roller 3053 is used to fix and guide the pipe, ensuring that the pipe is fixed in place and in the right position.

[0040] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
