Description

Technical Field

[0001] The invention relates to the technical field of workpiece thermal spraying, and in particular to an automatic heating system for thermal spraying workpieces with intelligent temperature control. Background Art

[0002] In current industrial production, workpiece heating treatment is a crucial process, which is widely used in many fields such as metal processing, surface treatment, heat treatment, etc. Traditional heating equipment and technology have significant deficiencies in controlling temperature accuracy, heating efficiency and energy utilization.

[0003] In the process of heating the workpiece, thermal inertia will be generated. Thermal inertia refers to the time required for the heating element to reach a new steady state when the temperature changes. Specifically, when the heating element is acted upon by a heat source, its temperature will not immediately rise to a new stable value, but will undergo a gradual change process. Similarly, when the heat source is removed, the temperature of the heating element will not drop immediately, but will gradually approach the ambient temperature. This hysteresis of temperature change is the manifestation of thermal inertia. Due to the existence of thermal inertia, the system's response speed to temperature changes slows down, resulting in a large deviation between the actual temperature and the set temperature, thereby affecting the temperature control accuracy. In situations where rapid temperature rise is required, a large thermal inertia will prolong the heating time and reduce the heating efficiency. In addition, heat will rise according to the principles of thermodynamics and fluid mechanics, resulting in inconsistent temperatures above and below. The temperature above the workpiece is higher, causing the regional coating to overheat and generate stress and thermal stress, while the temperature below the workpiece is lower, causing the region to fail to reach the ideal spraying temperature, insufficient coating adhesion, and uneven heating speed and temperature distribution of various parts of the workpiece.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In a typical implementation of this application, please refer to Figures 1 to 10 As shown, an intelligent temperature-controlled automatic heating system for hot-spraying workpieces comprises a base 1, a workbench 2 is fixedly mounted on the top surface of the base 1, baffles 3 are fixedly mounted on both sides of the top surface of the workbench 2, a conveyor belt 4 is rotatably connected between the two baffles 3, and the conveyor belt 4 is used to transport the workpiece, a distribution box 5 is fixedly mounted on the left side wall of the base 1, and the distribution box 5 supplies power to various components inside the equipment, a controller 6 is fixedly mounted on the front side wall of one of the baffles 3, and the controller 6 can control various components inside the equipment, and can automatically adjust the temperature of the heating mechanism according to the type of the workpiece, so as to realize intelligence and automation;

[0031] Conductive grooves 32 are provided on adjacent surfaces of the two baffles 3, and carbon brush wheels 33 are slidably connected to the inner walls of the two conductive grooves 32;

[0032] In the above process, the conveyor belt 4 conveys the workpiece to the bottom of the heating mechanism for heating. After the heating is completed, the conveyor belt 4 conveys the workpiece to the next step for spraying.

[0033] The above process is the basic process of workpiece heating at present.

[0034] However, thermal inertia will be generated during the heating of the workpiece. Thermal inertia refers to the time required for the heating element 8 to reach a new steady state when the temperature changes. Specifically, when the heating element 8 is acted upon by a heat source, its temperature will not immediately rise to a new stable value, but will undergo a gradual change process. Similarly, when the heat source is removed, the temperature of the heating element 8 will not drop immediately, but will gradually approach the ambient temperature. This hysteresis in temperature change is a manifestation of thermal inertia. Due to the existence of thermal inertia, the system's response speed to temperature changes slows down, resulting in a large deviation between the actual temperature and the set temperature, thereby affecting the temperature control accuracy. In situations where rapid temperature rise is required, a large thermal inertia will prolong the heating time and reduce the heating efficiency.

[0035] In addition, according to the principles of thermodynamics and fluid mechanics, heat will rise, resulting in inconsistent temperatures above and below. The temperature above the workpiece is higher, causing the regional coating to overheat and generate stress and thermal stress, while the temperature below the workpiece is lower, causing the area to fail to reach the ideal spraying temperature, insufficient coating adhesion, and uneven heating rate and temperature distribution of various parts of the workpiece.

[0036] Therefore, based on the above problems, we first design a heating mechanism, which is arranged on the baffle 3. The heating mechanism includes: a protective shell 7, which is fixedly installed on the top surface of the baffle 3, and a plurality of heating elements 8 are fixedly installed inside the protective shell 7. The inner wall of the protective shell 7 and located below the heating elements 8 are rotatably connected to two metal reflective plates 10 through a rotating column 9. The two metal reflective plates 10 are symmetrically arranged, and the outer surfaces of the two metal reflective plates 10 are fixedly installed with heat insulation curtains 11. The heating mechanism also includes a circulation component, which includes: a plurality of circulation pipes 17, which are respectively arranged on the two side walls of the protective shell 7, and circulation boxes 18 are fixedly installed on the inner walls on both sides of the protective shell 7. One ends of the plurality of circulation pipes 17 are respectively connected to the interior of the two circulation boxes 18, and the other ends respectively penetrate the side walls of the two baffles 3 and extend to the top of the conveyor belt 4. A plurality of circulation ports 19 are opened on the adjacent surfaces of the two circulation boxes 18, and metal sheets 20 are fixedly installed inside the plurality of circulation ports 19 through limiting rods 21.

[0037] Through the above features, the problems of poor temperature control accuracy and low heating efficiency and uneven heating speed and temperature distribution of various parts of the workpiece caused by thermal inertia are solved. Specifically, the staff controls the driving component through the protective shell 7 so that the driving component closes the two metal reflective plates 10. At this time, the heating element 8 is turned on by the controller 6 to heat it. During this heating process, the heat generated will be reflected to the heating element 8 through the two metal reflective plates 10 to accelerate the heating element 8 to reach the specified temperature more quickly. Then the staff puts the workpiece on the conveyor belt 4, turns on the conveyor belt 4 through the controller 6 so that the conveyor belt 4 drives the workpiece to enter the bottom of the protective shell 7 and then stops. At this time, after the heat reaches the specified temperature, the two metal reflective plates 10 are unfolded by the driving component and cover the workpiece to prevent heat loss. At the same time, the metal sheet 20 reaches the specified temperature, causing the metal sheet 20 to be rolled up, so that the metal sheet 20 is sealed at the convection port 19, and the heat above the inside of the protective shell 7 will flow into one end of the circulation pipe 17 through the circulation port 19, and flow out at the other end of the circulation pipe 17 to form a cycle, so that the heat is always maintained at a uniform height.

[0038] As a preferred implementation in this embodiment, please refer to Figure 5 As shown, the driving assembly is arranged on the outer wall of the protective shell 7 and is used to open or close the metal reflective plate 10. The driving assembly includes: two connecting columns 12, the two connecting columns 12 are respectively rotatably connected to the outer wall of the protective shell 7, one end of the two connecting columns 12 is respectively connected to the side walls of the two rotating columns 9, and the other ends of the two connecting columns 12 are fixedly installed with a worm gear 13. Two fixing rings 14 are fixedly installed on the outer wall of the protective shell 7 and located below the worm gear 13. A worm 15 is rotatably connected between the two fixing rings 14. The worm 15 is meshed with the worm gear 13, and two sections of spiral teeth with opposite rotation directions are arranged on the worm 15. A driving motor 16 is fixedly installed on the side wall of one of the fixing rings 14, and the output shaft of the driving motor 16 is connected to the side wall of the worm 15.

[0039] Through the above-mentioned features, the two metal reflective plates 10 can be opened or closed. Specifically, when the metal reflective plates 10 are opened, the staff turns on the drive motor 16 through the controller 6 to rotate the worm 15 connected to the output shaft of the drive motor 16. The worm 15 is provided with two sections of spiral teeth with opposite rotation directions, which are respectively engaged with the two worm gears 13 to rotate the two worm gears 13. While the two worm gears 13 are rotating, the connecting column 12 connected to the worm gear 13 and the rotating column 9 connected to the connecting column 12 will rotate synchronously, so that the two metal reflective plates 10 are symmetrically unfolded. When the metal reflective plates 10 need to be closed, it is only necessary to rotate the drive motor 16 in the opposite direction through the controller 6.

[0040] As a preferred implementation in this embodiment, please refer to Figure 8 As shown, the heat dissipation component is arranged on the top surface of the protective shell 7 and is used to dissipate the heat inside the protective shell 7. The heat dissipation component includes: a protective plate 22, the protective plate 22 is fixedly mounted on the top surface of the protective shell 7, a card slot 23 is provided on the side wall of the protective plate 22, a plurality of heat dissipation ports 24 are provided in the card slot 23 on the top surface of the protective shell 7, and the plurality of heat dissipation ports 24 are communicated with the interior of the protective shell 7, a circular groove 29 is provided on the top surface of the protective plate 22, a connecting block 30 is fixedly mounted inside the circular groove 29 through a heat dissipation fan 31, and the heat dissipation component also includes a sealing member, which includes: a fixed plate 25, the fixed plate 25 is fixedly mounted on the top surface of the protective shell 7 and is located on one side of the protective plate 22, an electric push rod 26 is fixedly mounted on the surface of the fixed plate 25 facing the protective plate 22, a sealing block 27 is fixedly mounted on the output shaft of the electric push rod 26, and the sealing block 27 slides on the card slot 23, and a switch 28 is fixedly mounted on one side of the fixed plate 25 on the top surface of the protective shell 7;

[0041] Through the above-mentioned features, the heat inside the protective shell 7 can be quickly discharged after the heating is completed. Specifically, the staff turns on the electric push rod 26 through the controller 6 to make the electric push rod 26 shrink, so that the sealing block 27 connected to the output shaft of the electric push rod 26 slides out of the slot 23. When the electric push rod 26 drives the sealing block 27 to shrink to the maximum position, one side of the sealing block 27 or touches the switch 28, so that the cooling fan 31 is turned on, and the heat inside the protective shell 7 is discharged through the heat dissipation port 24, the slot 23 and the circular groove 29 in turn. When the heat in the protective shell 7 is completely discharged, the electric push rod 26 will drive the sealing block 27 to seal the heat dissipation port 24 to prevent foreign matter such as dust from flowing into the interior of the protective shell 7. When the sealing block 27 moves, the contact with the switch 28 will be disconnected, so that the cooling fan 31 stops working.

[0042] As a preferred implementation in this embodiment, please refer to Figure 4 and Figure 6As shown, the flipping assembly is arranged on the baffle 3 and is used to flip the workpiece being heated. The flipping assembly includes: two L-shaped plates 34, the two L-shaped plates 34 are respectively fixedly mounted on the side walls of the two carbon brush wheels 33, and the side walls of the two L-shaped plates 34 are fixedly mounted with cameras 35. A connecting plate 36 is fixedly mounted on the top surface of the L-shaped plate 34, and a moving groove 38 is opened on the bottom surface of the connecting plate 36. A mechanical arm 37 is arranged below the connecting plate 36 through a moving part, and the moving part includes: a threaded rod 39, ... The rod 39 is rotatably connected to the inner wall of the movable groove 38, and a movable block 40 is threadedly connected to the outer surface of the threaded rod 39. The movable block 40 slides on the movable groove 38. A disc 41 is fixedly installed on the bottom surface of the movable block 40, and the bottom surface of the disc 41 is fixedly connected to the top surface of the robotic arm 37. A heat insulation cover 43 is fixedly installed on the side wall of the connecting plate 36. A drive motor 42 is fixedly installed on the side wall of the connecting plate 36 and inside the heat insulation cover 43. The output shaft of the drive motor 42 is connected to the side wall of the threaded rod 39.

[0043] Through the above-mentioned features, the workpiece on the conveyor belt 4 can be turned over. Specifically, when the workpiece is located under the protective shell 7, the flipping assembly is also located under the protective shell 7, so that the mechanical arm 37 can turn the workpiece over. When the mechanical arm 37 needs to move left and right, the staff energizes the conductive slot 32 through the controller 6, so that the carbon brush wheel 33 can slide in the conductive slot 32. When the carbon brush wheel 33 slides, the L-shaped plate 34 will also move, so that the connecting plate 36 connected to the L-shaped plate 34 and the mechanical arm 37 connected to the connecting plate 36 will move synchronously. When the mechanical arm 37 needs to move forward and backward, the staff only needs to turn on the drive motor 2 42 through the controller 6 to make the output shaft of the drive motor 2 42 The connected threaded rod 39 rotates to make the moving block 40 threadably connected to the threaded rod 39 move on the moving groove 38, and the bottom surface of the moving block 40 is connected to the top surface of the disk 41, and the bottom surface of the disk 41 is connected to the top surface of the robot arm 37, so that when the moving block 40 moves, the disk 41 and the robot arm 37 will move synchronously, and the camera 35 can monitor the position of the workpiece. The camera 35 uses a furnace endoscopy high-temperature camera, which is the RB-TV series, and transmits it to the controller 6. The controller 6 makes the robot arm 37 work to turn the workpiece over according to the signal transmitted by the camera 35. The heat insulation cover 43 can protect the drive motor 2 42 to avoid damage caused by excessive heat.

[0044] Working principle:

[0045] During use, when the device is in the initial state, the two metal reflective plates 10 are in a closed state, and the worm 15 is controlled to rotate by the drive motor 16 in the drive assembly, so that the two worm wheels 13 drive the connecting column 12 and the rotating column 9 to rotate, thereby making the metal reflective plates 10 symmetrically closed to protect the heating element 8 and reduce heat loss. At this time, the sealing block 27 in the heat dissipation assembly tightly closes the heat dissipation port 24 under the action of the electric push rod 26 to prevent external dust from entering the protective shell 7. The staff starts the heating element 8 through the controller 6, and the heating element 8 starts to generate heat. Due to the closure of the metal reflective plate 10, the heat is reflected back to the surrounding of the heating element 8, accelerating the heating. The process of the element 8 reaching the set temperature effectively reduces the problem of prolonged heating time caused by thermal inertia. At the same time, the heat insulation curtain 11 on the metal reflector 10 further reduces the heat loss. When the heating element 8 reaches the set temperature, the staff places the workpiece to be heated on the conveyor belt 4, and starts the conveyor belt 4 through the controller 6 to transfer the workpiece to the bottom of the protective shell 7. At this time, the conveyor belt 4 stops and the workpiece stays directly under the protective shell 7. Subsequently, the controller 6 controls the drive motor 16 to rotate in the opposite direction, so that the metal reflector 10 is unfolded and the workpiece is covered in the protective shell 7 to ensure that the heat is concentrated and evenly acts on the workpiece. During the heating process, the heat inside the protective shell 7 The heat circulates through the circulation component, and the heat enters the circulation pipe 17 from the top of the protective shell 7 through the circulation port 19, and then flows to the inside of the protective shell 7 after passing through the top of the conveyor belt 4, forming a circulation, ensuring that the heat is evenly distributed inside the protective shell 7, solving the problem of inconsistent temperatures between the upper and lower parts of the workpiece. When one side of the workpiece is heated, the controller 6 controls the conductive slot 32 to be energized according to the workpiece position information transmitted by the camera 35, so that the carbon brush wheel 33 slides in the conductive slot 32, driving the L-shaped plate 34, the connecting plate 36 and the mechanical arm 37 to move as a whole to the top of the workpiece. Subsequently, the controller 6 starts the driving motor 2 42, drives the threaded rod 39 to rotate, and moves the moving block 40 on the moving slot 38. , and then drives the mechanical arm 37 to turn over the workpiece. During the turning process, the heat insulation cover 43 protects the drive motor 2 42 from the influence of high temperature. After both sides of the workpiece are heated to the set temperature, the conveyor belt 4 is restarted to transfer the workpiece to the next process for spraying. At this time, the controller 6 controls the electric push rod 26 to contract, so that the sealing block 27 slides out of the slot 23, and the trigger switch 28 starts the cooling fan 31. The cooling fan 31 discharges the heat inside the protective shell 7 through the heat dissipation port 24, the slot 23 and the circular groove 29, ensuring that the equipment cools down quickly and prepares for the next heating process. When the heat is discharged, the electric push rod 26 drives the sealing block 27 to reset and re-close the heat dissipation port 24.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
