Description

Technical Field

[0001] This invention belongs to the field of surface coating technology, specifically relating to an automated device for fluidized bed coating, which is a device used in surface coating processes. Background Technology

[0002] In production, the inner and outer surfaces of some complex parts need to be coated. Due to the high quality requirements of the coating of the inner hole grooves of the parts, the thickness error of the entire coating layer cannot exceed 0.1mm. The surface coating process must strictly control various process parameters to ensure the uniformity of the coating layer thickness and the adhesion strength of the parts.

[0003] Current surface coating is typically done manually. This method cannot automate processes such as preheating, coating, and curing, nor can it precisely control parameters like vibration frequency, intensity, coating speed, temperature, and time. Consequently, it is inefficient and produces low-quality products. Therefore, improvements are necessary. Summary of the Invention

[0004] The technical problem solved by this invention is to provide an automated equipment for fluidized bed coating. This invention replaces traditional manual operations with automated equipment for surface coating of parts. It can realize the automatic processing of parts preheating, surface coating and drying curing, and can accurately control various parameters in the process, resulting in high work efficiency and good coating quality of parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Automated equipment for fluidized bed coating, including a constant temperature conveying mechanism, a coating tank, and a clamping and swinging mechanism;

[0007] The constant temperature conveying mechanism includes two constant temperature tunnel ovens, one of which is located at the front end for the preheating and heat preservation area of ​​the parts to be coated, and the other is located at the rear end for the constant temperature curing area of ​​the parts after coating.

[0008] A coating bucket is fixedly installed between the preheating and insulation zone and the constant temperature curing zone. The upper part of the coating bucket is equipped with a clamping and swinging mechanism. The clamping and swinging mechanism can clamp the parts and drive the parts to move back and forth between the preheating and insulation zone and the constant temperature curing zone for transportation. The parts can also move up and down and swing to achieve coating in the coating bucket.

[0009] The coating bucket comprises an upper coating bucket and a lower support base, with the upper coating bucket supported on the lower support base.

[0010] The upper coating tank includes a coating tank body, which is fixedly mounted on the upper part of the support base I. The bottom of the coating tank body is provided with an air distribution plate and a microporous fluidizing plate. The air distribution plate is placed below the microporous fluidizing plate. The support base I has an air inlet on one side that is connected to the air passage of the air distribution plate.

[0011] The lower support includes a support base plate, an adjustable support foot at the bottom of the support base plate, a vibration damper vertically mounted on the upper part of the support base plate, a support seat I fixedly supported on the upper part of the vibration damper, a pneumatic vibrator fixed at the lower center of the support seat I, and a support base shell for enclosing the internal components on the support base plate and the support seat I. An adjustable flow meter is fixed on the side wall of the support base shell and connected to the air inlet.

[0012] Furthermore, the air holes on the air distribution plate are arranged in a ring, with each ring of air holes supplying air individually, so that the pressure and flow rate of each air hole are consistent, and each air hole is trumpet-shaped.

[0013] Furthermore, the vibration damper includes a linear bearing, a cylindrical guide rail, a damping spring, and a vibration damper base. The vibration damper base is fixed on the base plate of the support seat. A cylindrical guide rail is vertically fixed on the upper part of the vibration damper base. A damping spring is sleeved on the outside of the cylindrical guide rail. A linear bearing is sleeved on the top of the cylindrical guide rail. The linear bearing is connected to the bottom of the support seat I.

[0014] The clamping swing mechanism includes a linear module located at the upper part between the preheating and heat preservation zone and the constant temperature curing zone. The linear module can move left and right along the upper guide rail, and the guide rail is provided with limit blocks at both ends. A lifting cylinder is fixedly connected to the lower part of the linear module, and a cam swing mechanism is fixedly connected to the lower end of the lifting cylinder. A clamping cylinder is fixedly connected to the lower end of the cam swing mechanism.

[0015] Furthermore, the cam swing mechanism includes a frame, a servo motor, a cam, a swing rod, and a limit rod; the frame is fixed to the lower end of the lifting cylinder, the servo motor is fixed on the frame, a cam is fixedly sleeved on the output shaft of the servo motor, the upper end of the swing rod is hinged to the front of the frame, one side of the swing rod is a cam, both sides of the swing rod are provided with limit rods, the limit rods are fixed on the frame, and the lower end of the swing rod is connected to a clamping cylinder.

[0016] Furthermore, both constant temperature tunnel furnaces in the constant temperature conveying mechanism include a conveyor belt and a conveyor belt frame. Conveyor belt bases for placing parts are evenly distributed on the conveyor belt. Conveyor lifting doors are provided at the upper front and rear ends of the conveyor belt frame. The conveyor lifting doors are connected and driven by lifting door cylinders fixedly installed on the upper part of the frame.

[0017] Advantages of this invention compared to existing technologies:

[0018] 1. This solution integrates components such as a constant temperature conveying mechanism, a coating tank, and a clamping swing mechanism. Parts enter the preheating and insulation zone through a lifting door. After the required preheating and insulation time is reached, the preheated parts are conveyed to the coating waiting area through the lifting door. The clamping swing mechanism clamps the parts and transports them above the coating tank, allowing the parts to move along the process-specified trajectory within the coating tank. The clamping swing mechanism carries the parts in a circular motion, swinging downwards and then to the right and left, as well as an upward lifting motion. After coating, the clamping swing mechanism transports the parts and places them on the conveyor belt in front of the constant temperature curing zone and releases the parts. When the lifting door of the curing and insulation zone is opened, the parts enter the curing and insulation zone. After the curing and insulation time reaches the required process time, the parts are conveyed to the outside of the equipment through the lifting door, and the surface coating of the parts is completed. This automatic surface coating equipment can precisely control multiple process parameters such as heating temperature, heating time, coating motion trajectory, coating speed, vibration intensity, and vibration frequency, replacing the original manual operation method that relied on human experience to control various process parameters. It can realize the automated production of parts coating process, which not only improves product quality but also greatly improves product production efficiency.

[0019] 2. This solution is used to replace manual labor, and the manufacturing process can ensure good product consistency and high efficiency.

[0020] 3. This solution features a compact and simple structure, easy manufacturing, wide applicability, low cost, convenient use and adjustment, high control precision, high efficiency, and good product consistency. It can easily adjust various process parameters and can well meet the needs of mass production of coatings for the inner and outer surfaces of various small parts. Attached Figure Description

[0043] 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.

[0044] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0045] Please see Figure 1-22 The embodiments of the present invention are described in detail below.

[0046] Example: Automated equipment for fluidized bed coating, see [link / reference] Figure 1 As shown, it includes a constant temperature conveying mechanism 1, a coating tank 2, and a clamping swing mechanism 3;

[0047] The constant temperature conveying mechanism 1 includes two constant temperature tunnel furnaces, one of which is located at the front end for the preheating and heat preservation zone 1-1 of the parts to be coated, and the other is located at the rear end for the constant temperature curing zone 1-2 of the parts after coating.

[0048] A coating bucket 2 is fixedly installed between the preheating and insulation zone 1-1 and the constant temperature curing zone 1-2. The upper part of the coating bucket 2 is equipped with a clamping and swinging mechanism 3. The clamping and swinging mechanism 3 can clamp the parts and drive the parts to move back and forth between the preheating and insulation zone 1-1 and the constant temperature curing zone 1-2 for transportation. It can also move up and down and swing to achieve coating of the parts in the coating bucket 2.

[0049] In this embodiment, the constant temperature conveying mechanism 1 precisely controls the part temperature, part holding time, and part conveying position; the coating tank 2 can control the vibration frequency, vibration intensity, coating suspension height, and coating concentration during surface coating; the clamping and swinging mechanism 3 can mimic manual coating operations and precisely control the coating movement trajectory and working speed. The overall device facilitates the control of various production process parameters, replacing the production method that relies on manual experience to control process parameters. It can meet the process requirements for coating the inner and outer surfaces of various small parts, improve production efficiency, save labor, and is suitable for the mass production of small parts.

[0050] In one embodiment, see Figure 2As shown, the two constant temperature tunnel furnaces in the constant temperature conveying mechanism 1 each include a conveyor belt 1-3 and a conveyor belt frame. Conveyor belt bases 1-4 for placing parts are evenly distributed on the conveyor belt 1-3. Conveyor lifting doors 1-5 are provided at the upper front and rear ends of the conveyor belt frame. The conveyor lifting doors 1-5 are connected and driven by lifting door cylinders 1-6 fixedly installed on the upper part of the frame.

[0051] In one embodiment, see Figure 3 As shown, the coating bucket 2 includes an upper coating bucket and a lower support base, with the upper coating bucket supported on the lower support base.

[0052] For details, please refer to Figure 4 As shown, the upper coating tank includes a coating tank body 2-1, which is fixedly mounted on the upper part of the support base I 2-11. The bottom of the coating tank body 2-1 is provided with a gas distribution plate 2-2 and a microporous fluidizing plate 2-3. The gas distribution plate 2-2 is placed below the microporous fluidizing plate 2-3. The support base I 2-11 is provided with an air inlet 2-4 on one side that is connected to the gas path of the gas distribution plate 2-2.

[0053] For details, please refer to Figure 7 As shown, the lower support includes a support base plate 2-5, an adjustable support foot 2-7 at the bottom of the support base plate 2-5, a vibration damper 2-8 vertically mounted on the top of the support base plate 2-5, a support seat I 2-11 fixedly supported on the top of the vibration damper 2-8, a pneumatic vibrator 2-9 fixed at the center of the lower part of the support seat I 2-11, and a support base shell 2-6 for enclosing the internal components on the outside of the support base plate 2-5 and the support seat I 2-11, an adjustable flow meter 2-10 fixed on the side wall of the support base shell 2-6, and the adjustable flow meter 2-10 connected to the air inlet 2-4.

[0054] Preferred options, please refer to Figure 5 and 6 As shown, the air holes on the air distribution plate 2-2 are arranged in a ring, with each ring of air holes supplying air individually, so that the pressure and flow rate of each air hole are as consistent as possible. Each air hole is funnel-shaped, so that the gas is blown evenly onto the fluidizing plate as much as possible. Compared with ordinary air distribution plates, the airflow distribution is more uniform and the fluidization effect is better.

[0055] Preferred options, please refer to Figure 8-10As shown, the vibration damper 2-8 includes a linear bearing 2-8-1, a cylindrical guide rail 2-8-2, a damping spring 2-8-3, and a vibration damper base 2-8-4. The vibration damper base 2-8-4 is fixed on the support base plate 2-5. The cylindrical guide rail 2-8-2 is vertically fixed on the upper part of the vibration damper base 2-8-4. The damping spring 2-8-3 is sleeved on the outside of the cylindrical guide rail 2-8-2. The linear bearing 2-8-1 is sleeved on the top of the cylindrical guide rail 2-8-2. The linear bearing 2-8-1 is connected to the bottom of the support base I 2-11.

[0056] In this structure, the vibration of the coating tank is mainly generated by the up-and-down vibration of the pneumatic vibrator. The linear bearing of the damper moves up and down along the cylindrical guide rail. The spring can eliminate a certain degree of up-and-down vibration. The damper ensures that the coating tank can move up and down to a certain extent without tilting to the left or right. Compared with ordinary spring dampers for ordinary coating tanks, the fluidized layer always remains horizontal, resulting in a better coating effect.

[0057] In one embodiment, see Figure 11 As shown, the clamping swing mechanism 3 includes a linear module 3-1 located at the upper part between the preheating and heat preservation zone 1-1 and the constant temperature curing zone 1-2. The linear module 3-1 can move left and right along the upper guide rail 3-6. Limiting blocks 3-7 are provided at both ends of the guide rail 3-6. A lifting cylinder 3-2 is fixedly connected to the lower part of the linear module 3-1. A cam swing mechanism 3-3 is fixedly connected to the lower end of the lifting cylinder 3-2. A clamping cylinder 3-4 is fixedly connected to the lower end of the cam swing mechanism 3-3. The clamping cylinder is used to clamp the part fixture 3-5 on which the part is fixed.

[0058] Preferred options, please refer to Figure 12-13 As shown, the cam swing mechanism 3-3 includes a frame 3-3-1, a servo motor 3-3-2, a cam 3-3-3, a swing rod 3-3-4, and a limit rod 3-3-5. The frame 3-3-1 is fixed to the lower end of the lifting cylinder 3-2. The servo motor 3-3-2 is fixed on the frame 3-3-1. The cam 3-3-3 is fixedly sleeved on the output shaft of the servo motor 3-3-2. The upper end of the swing rod 3-3-4 is hinged to the front of the frame 3-3-1. One side of the swing rod 3-3-4 is the cam 3-3-3. Limit rods 3-3-5 are provided on both sides of the swing rod 3-3-4. The limit rods 3-3-5 are fixed on the frame 3-3-1. The lower end of the swing rod 3-3-4 is connected to the clamping cylinder 3-4.

[0059] In this structure, a servo motor drives a cam to move, which in turn drives a swing arm to perform an arc motion, replacing the manual arc motion during coating. A limit rod restricts the position of the swing arm, ensuring that the motion trajectory remains within the required process range. The servo motor can be set to position the workpiece, and after the coating arc motion is completed, it can quickly return to the workpiece clamping position (swing arm vertically downward). The cam swing mechanism moves as follows: Figure 14 As shown.

[0060] The specific implementation process of this automated fluidized bed coating equipment is as follows:

[0061] 1. Load the parts into the parts fixture and install it onto the conveyor belt base, such as... Figure 15 As shown;

[0062] 2. The fixture containing the parts preheats the parts to be coated in the front-end constant-temperature tunnel oven. After passing through the lifting door and stopping at the predetermined position, the clamping cylinder of the clamping swing mechanism clamps the fixture containing the parts. For example... Figure 16 As shown:

[0063] 3. The linear module of the clamping swing mechanism moves the part fixture above the coating tank to prepare for coating the part. For example... Figure 17 As shown:

[0064] 4. Compressed air is introduced into the coating tank, causing the coating to fluidize. The lifting cylinder of the clamping swing mechanism moves downward into the coating tank, and the cam swing mechanism drives the part fixture to move in an arc to the left. When the swing rod reaches the left limit rod, the swing rod stops swinging. Figure 18 As shown:

[0065] 5. The cam continues to rotate, causing the swing arm to swing to the right. It stops swinging when it reaches the right limit bar, thus replacing the circular motion of manual coating. For example... Figure 19 As shown:

[0066] 6. After the circular motion of the coating is completed, the servo motor of the clamping swing mechanism drives the cam and swing rod back to the middle position, and the lifting cylinder rises to lift the part out of the coating barrel, thus completing the coating process. Figure 20 As shown;

[0067] 7. The linear module moves the coated part fixture onto the conveyor belt of the rear-end constant-temperature curing tunnel oven. For example... Figure 21 As shown;

[0068] 8. The clamping cylinder of the clamping swing mechanism releases the part fixture, the rear constant temperature curing tunnel oven opens its lifting door, and the part fixture enters the curing and heat preservation zone inside the oven. After the required process time is reached, the lifting door on the other side opens, and the conveyor belt transports the part fixture to the outside of the equipment. The surface coating of the part is then complete. Figure 22 As shown.

[0069] In this invention, the constant temperature conveying mechanism is used for preheating, drying and curing of parts, and can accurately control the part temperature, part holding time and part conveying position, and accurately transport the parts to each station of the equipment; the coating bucket is used for surface coating of parts, and can control the vibration frequency, vibration intensity, suspension height of the coating and the concentration of the coating. The unique air distribution plate and vibration damper make the coating thickness of the part surface more uniform; the clamping swing mechanism is used to imitate manual coating operation, and can accurately control the motion trajectory and working speed of the coating.

[0070] This fluidized bed coating automation equipment can precisely control various parameters in the surface coating process, replacing the production method that relies on manual experience to control process parameters. It can meet the process requirements of coating the inner and outer surfaces of various small parts, with high production efficiency, saving labor, and is suitable for automated mass production of surface coating for small parts.
