Description

Technical Field

[0001] This utility model relates to the field of air conditioning parts manufacturing technology, and in particular to a duct shaping mechanism and duct production system. Background Technology

[0002] The air duct structure of an air conditioning indoor unit is a crucial component of the air conditioning system, serving multiple functions such as airflow guidance, distribution, filtration, cooling or heating, and humidity regulation. Currently, the air ducts of air conditioning indoor units are primarily made of ABS engineering plastic. ABS plastic is a terpolymer of acrylonitrile (A), butadiene (B), and styrene (S), combining the properties of all three components: acrylonitrile provides high hardness and strength, heat resistance, and corrosion resistance; butadiene offers impact resistance and toughness; and styrene contributes high surface gloss, ease of coloring, and ease of processing. However, ABS material also has some limitations, particularly its susceptibility to shrinkage and deformation under the influence of mold temperature and ambient temperature. In a vertical cylindrical air conditioning indoor unit, the entire air supply system consists of components such as the air duct, cross-flow fan blades, volute, sweeping blades, and end caps. The design clearance between the air duct and the fan blades must be greater than 3mm. However, due to the excessive length of the indoor unit's air duct, abnormal deformation can easily occur during the cooling and placement process after molding. This deformation can cause friction between the duct edge and the high-speed rotating fan blades after the duct is assembled, generating noise and severely impacting the customer experience. Therefore, it is necessary to detect the deformation of the duct during production to determine its quality. However, current duct inspections are mostly done manually. Manual inspection is not only inefficient but also cannot correct the shape of the duct, hindering efforts to reduce production costs.

[0003] Therefore, it is necessary to improve the existing production and testing process of air conditioning ducts to overcome the shortcomings of the existing technology. Utility Model Content

[0004] To overcome the problems existing in related technologies, one of the objectives of this utility model is to provide a duct shaping mechanism that can precisely extrude and shape the duct, ensuring that the shaped duct meets the design requirements, improving product quality and consistency, and helping to improve duct production efficiency and reduce production costs.

[0005] A duct shaping mechanism includes a main body with a duct placement position. A shaping mechanism is provided on one side of the duct placement position. The shaping mechanism includes a shaping drive device and a shaping plate. The shaping drive device is fixed on the main body, and the shaping plate is disposed at the output end of the shaping drive device. The shaping drive device drives the shaping plate to move closer to or away from the duct placement position to achieve duct shaping.

[0006] The shaping drive device can be a cylinder, an electric push rod, or other type of linear drive device, and its output end is connected to the shaping plate. The shaping plate is designed to match the straight edge of the air duct so that the deformed air duct can be accurately shaped during the shaping process.

[0007] The process of shaping the air duct in this institution is as follows: After the air duct is formed and produced, a robotic arm picks up the air duct and places it in the air duct placement position.

[0008] The position of the air duct is detected by photoelectric sensors to ensure correct placement. The shaping drive device is activated, driving the shaping plate closer to the air duct placement position to shape the air duct. After shaping, the shaping plate retracts, and the robotic arm removes the shaped air duct, ending the shaping process.

[0009] This duct shaping mechanism replaces traditional manual shaping operations with an automated shaping drive, significantly improving duct production efficiency and reducing labor costs. Furthermore, because the shaping process is machine-controlled, it ensures consistent shaping quality for each duct, avoiding inconsistencies and errors caused by manual operation. In addition, the shaping structure is flexible in design, adaptable to ducts of different sizes and shapes, and possesses high versatility.

[0010] In a preferred embodiment of this invention, a clamping mechanism is provided at the edge of the air duct placement position. The clamping mechanism includes a clamping drive device and a clamp. The clamping drive device is disposed on the main body, and the clamp is disposed at the output end of the clamping drive device. The clamping drive device drives the clamp to move closer to or away from the air duct placement position to achieve stable clamping of the air duct.

[0011] In a preferred embodiment of this utility model, two clamping mechanisms are provided along the length of the air duct placement position, and the two clamping mechanisms are respectively located at both ends of the air duct placement position.

[0012] The shaping mechanism is located on one side along the width direction of the air duct placement position.

[0013] This design ensures the stability of the air duct during the shaping process and prevents the air duct from shifting or rotating during shaping.

[0014] During duct shaping, two clamping mechanisms clamp the duct from both ends of the duct placement position to ensure the stability of the duct during the shaping process, prevent the duct from shifting or rotating during shaping, and improve the accuracy of shaping.

[0015] In a preferred embodiment of this invention, the clamp includes a clamping plate and a buffer plate. The clamping plate is disposed at the output end of the clamping drive device, and the buffer plate is disposed on the side of the clamping plate opposite to the clamping drive device.

[0016] During clamping, the buffer plate prevents the clamping plate from directly contacting the air duct, reducing scratches, indentations, or other forms of damage to the air duct surface caused by clamping. When the clamping drive device drives the clamping plate to clamp the air duct, the buffer plate absorbs the impact force generated by rapid clamping or releasing actions, thereby reducing impact damage to the air duct. In practical applications, the presence of the buffer plate increases the contact area between the clamping mechanism and the air duct, improving clamping stability and ensuring that the air duct does not shift due to insecure clamping during the shaping process.

[0017] In a preferred embodiment of this utility model, the main body is further provided with a lifting mechanism, which includes a lifting drive device and a lifting seat. The lifting drive device is fixed on the main body, the lifting seat is disposed at the output end of the lifting drive device, and the clamping mechanism is disposed on the lifting seat.

[0018] In practical use, the lifting drive unit moves the lifting seat vertically to adjust the height of the clamping mechanism relative to the air duct placement position. By configuring the lifting mechanism, the height of the clamping mechanism can be adjusted according to the actual height of the air duct, ensuring that the clamping mechanism can adapt to air ducts of different sizes. The lifting mechanism allows the clamping mechanism to move vertically, increasing operational flexibility and making the shaping process smoother. Furthermore, the automated control of the lifting mechanism reduces manual operation, improving production efficiency and operational safety.

[0019] In a preferred embodiment of this invention, two shaping drive devices are provided, which are symmetrical about the center of gravity of the shaping plate, and the output ends of both shaping drive devices are connected to the shaping plate; a shaping head is provided on the shaping plate, and the shaping head is located on the side of the shaping plate away from the shaping drive devices.

[0020] By symmetrically arranging two shaping drive devices, it is ensured that the shaping plate is subjected to uniform force during the shaping process, avoiding plate skewing or uneven duct shaping caused by unbalanced driving forces. The symmetrical drive devices improve shaping accuracy, ensuring that the dimensions and shape of the duct after shaping meet design requirements. Furthermore, uniform shaping force reduces the risk of damage to the duct during the shaping process, improving its integrity and durability.

[0021] In this embodiment, the shaping head is connected to the air duct, avoiding direct contact between the shaping plate and the air duct. In actual use, the shaping head can be made of rubber to prevent damage to the air duct during the shaping process.

[0022] In a preferred embodiment of this utility model, the main body is further provided with an angle adjustment mechanism, which includes an angle adjustment drive device and an angle adjustment plate. The angle adjustment drive device is fixed on the main body, and the axis of the output end of the angle adjustment drive device is perpendicular to the horizontal plane. The angle adjustment plate is disposed at the output end of the angle adjustment drive device, and one side of the angle adjustment plate is hinged to the main body. The shaping mechanism is disposed on the angle adjustment plate.

[0023] In this embodiment, the angle adjustment drive device can adjust the angle of the angle adjustment plate relative to the main frame. The shaping mechanism is set on the angle adjustment plate and can change the shaping angle as the angle adjustment plate rotates. The shaping process of the air duct in this embodiment is as follows: After the air duct is formed and produced, a robot arm picks up the air duct and places it in the air duct placement position.

[0024] The angle adjustment drive device adjusts the angle adjustment plate to the appropriate position, enabling the shaping mechanism to precisely shape the air duct. Two shaping drive devices are activated simultaneously, symmetrically driving the shaping plate closer to the air duct placement position to shape the air duct.

[0025] This embodiment adds an angle adjustment mechanism to the main body, enabling the shaping mechanism to shape the air duct at a precise angle, thus improving the accuracy and quality of the shaping. It also adapts to air ducts of different shapes and sizes, enhancing the versatility and applicability of the shaping structure. The angle adjustment mechanism provides more operational dimensions, making the shaping process more flexible and allowing adjustments based on the specific needs of the air duct.

[0026] In a preferred embodiment of this invention, a pressure sensor is provided on the shaping head, and the pressure sensor is located on the side of the shaping head opposite to the shaping drive device.

[0027] Pressure sensors are used to monitor the pressure applied to the air duct by the shaping head in real time.

[0028] The sensor data can be fed back to the mechanism's control system, which adjusts the force of the shaping drive device based on the received data to ensure the uniformity and precision of pressure during the shaping process. By controlling the shaping pressure, the risk of damage to the air duct during the shaping process can be reduced, improving the integrity and durability of the air duct. Precise pressure control can reduce errors and rework during the shaping process, thereby improving production efficiency.

[0029] In a preferred embodiment of this invention, a deformation detection sensor is provided at the edge of the air duct placement position, and the deformation detection sensor is positioned facing the air duct placement position.

[0030] The deformation detection sensor in this embodiment is used to monitor the deformation of the air duct in its placement position in real time.

[0031] Sensors can detect changes in the dimensions of the air duct before and after reshaping, ensuring that the reshaping effect meets expectations.

[0032] During the duct shaping process, the control system adjusts the force of the shaping drive and the position of the shaping plate based on feedback data from the deformation detection sensors, ensuring the uniformity and accuracy of pressure during the shaping process. Real-time monitoring can prevent duct damage caused by over-shaping, improving the integrity and durability of the duct.

[0033] The second objective of this utility model is to provide an air duct production system, including a robotic arm and an air duct shaping mechanism as described above.

[0034] A robotic arm picks up the newly produced air duct and moves it to the air duct placement position in the air duct shaping mechanism. The air duct production system provided in this application, by integrating a robotic arm and an air duct shaping mechanism, automates air duct production, reduces manual intervention, and improves production efficiency. Furthermore, the system can adapt to the shaping of air ducts of different sizes and shapes, exhibiting high flexibility and adaptability.

[0035] The beneficial effects of this utility model are as follows:

[0036] This utility model provides an air duct shaping mechanism. The main body of the mechanism includes an air duct placement position, and a shaping mechanism is located on one side of the placement position. The shaping mechanism includes a shaping drive device and a shaping plate. The drive device is fixed to the main body, and the shaping plate is located at the output end of the drive device. The drive device drives the shaping plate closer to or away from the air duct placement position. In use, the air duct to be shaped is placed on the placement position. Then, the shaping drive device is activated, driving the shaping plate closer to the placement position to compress and shape the air duct. After shaping, the shaping drive device drives the shaping plate away from the placement position, and the shaped air duct is removed. This mechanism, through the shaping drive device and shaping plate, can precisely compress and shape the air duct, ensuring that the shaped air duct meets design requirements, thus improving product quality and consistency. Moreover, during the shaping process, simply placing the air duct on the placement position and activating the shaping drive device completes the shaping operation, greatly simplifying the process, improving work efficiency, and reducing production costs.

[0037] This application also provides an air duct production system including the aforementioned air duct shaping mechanism. After the air duct is formed, the production system can realize automatic detection and shaping of the air duct, which can overcome the inefficiency of manual air duct inspection and help enterprises reduce costs and increase efficiency.

[0047] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0048] The air duct structure of an air conditioning indoor unit is a crucial component of the air conditioning system, serving multiple functions such as airflow guidance, distribution, filtration, cooling or heating, and humidity regulation. Currently, the air ducts of air conditioning indoor units are primarily made of ABS engineering plastic. ABS plastic is a terpolymer of acrylonitrile (A), butadiene (B), and styrene (S), combining the properties of all three components: acrylonitrile provides high hardness and strength, heat resistance, and corrosion resistance; butadiene offers impact resistance and toughness; and styrene contributes high surface gloss, ease of coloring, and ease of processing. However, ABS material also has some limitations, particularly its susceptibility to shrinkage and deformation under the influence of mold temperature and ambient temperature. In a vertical cylindrical air conditioning indoor unit, the entire air supply system consists of components such as the air duct, cross-flow fan blades, volute, sweeping blades, and end caps. The design clearance between the air duct and the fan blades must be greater than 3mm. However, due to the excessive length of the indoor unit's air duct, abnormal deformation can easily occur during the cooling and placement process after molding. This deformation can cause friction between the duct edge and the high-speed rotating fan blades after the duct is assembled, generating noise and severely impacting the customer experience. Therefore, it is necessary to detect the deformation of the duct during production to determine its quality. However, current duct inspections are mostly done manually. Manual inspection of duct deformation is not only inefficient but also cannot correct the shape of the duct, hindering efforts to reduce production costs.

[0049] Based on this, this application provides an air duct shaping mechanism.

[0050] Example 1

[0051] like Figures 1-7 As shown, this embodiment provides a duct shaping mechanism 3, which includes a main body 1. The main body 1 has a duct placement position 11. A shaping mechanism 3 is provided on one side of the duct placement position 11. The shaping mechanism 3 includes a shaping drive device 31 and a shaping plate 32. The shaping drive device 31 is fixed on the main body 1. The shaping plate 32 is disposed at the output end of the shaping drive device 31. The shaping drive device 31 drives the shaping plate 32 to move closer to or away from the duct placement position 11 to achieve duct shaping.

[0052] The shaping drive device 31 can be a cylinder, an electric push rod, or other type of linear drive device, and its output end is connected to the shaping plate 32. The shaping plate 32 is designed to match the straight edge of the air duct so that the deformed air duct can be accurately shaped during the shaping process.

[0053] The process of shaping the air duct in this institution is as follows: After the air duct is formed and produced, it is picked up by a robotic arm and placed on the air duct placement position 11.

[0054] The position of the air duct is detected by photoelectric sensing to ensure that the air duct is correctly placed. The shaping drive device 31 is activated, driving the shaping plate 32 to approach the air duct placement position 11 to shape the air duct. After shaping is completed, the shaping plate 32 retracts, the robotic arm removes the shaped air duct, and the shaping process ends.

[0055] The duct shaping mechanism 3 replaces traditional manual shaping operations with an automated shaping drive device 31, significantly improving duct production efficiency and reducing labor costs. Furthermore, because the shaping process is machine-controlled, it ensures consistent shaping quality for each duct, avoiding inconsistencies and errors caused by manual operation. In addition, the shaping structure is flexible in design, adaptable to ducts of different sizes and shapes, and has high versatility.

[0056] In a preferred embodiment of this invention, a laser detector can be installed on one side of the air duct placement position 11 to detect whether the air duct is deformed, thereby determining whether the shaping mechanism 3 needs to be activated.

[0057] In another embodiment, each air duct placed in the air duct placement position 11 can be shaped. In this embodiment, the stroke of the shaping mechanism 3 is the same each time it is started. In this operation mode, if the air duct is not deformed, the shaping plate 32 will not push the air duct to shape it. If the air duct is deformed, the edge of the air duct will expand outward. Therefore, the shaping plate 32 will push the air duct under the push of the shaping drive device 31, thereby realizing the shaping of the air duct.

[0058] Example 2

[0059] This embodiment is an improvement on embodiment 1.

[0060] like Figures 1-7 As shown, in this embodiment, a clamping mechanism 2 is provided on the edge of the air duct placement position 11. The clamping mechanism 2 includes a clamping drive device 21 and a clamp. The clamping drive device 21 is disposed on the main body 1, and the clamp is disposed at the output end of the clamping drive device 21. The clamping drive device 21 drives the clamp to move closer to or away from the air duct placement position 11 to achieve stable clamping of the air duct.

[0061] More preferably, in this embodiment, two clamping mechanisms 2 are provided along the length direction of the air duct placement position 11, and the two clamping mechanisms 2 are respectively located at both ends of the air duct placement position 11;

[0062] The shaping mechanism 3 is located on one side along the width direction of the air duct placement position 11.

[0063] This design ensures the stability of the air duct during the shaping process and prevents the air duct from shifting or rotating during shaping.

[0064] During the duct shaping process, two clamping mechanisms 2 clamp the duct from both ends of the duct placement position 11 to ensure the stability of the duct during the shaping process, prevent the duct from shifting or rotating during the shaping process, and improve the accuracy of the shaping.

[0065] In practical applications, due to the long length of the air duct, the middle of the duct often deforms during the production process. Therefore, this application addresses this issue by installing clamping mechanisms 2 at both ends of the air duct to clamp it. A shaping mechanism 3 is also installed on one side of the air duct placement position 11 to shape the air duct. This layout is particularly suitable for placing long products.

[0066] Example 3

[0067] This embodiment is an improvement on embodiment 2.

[0068] like Figures 1-7 As shown, in this embodiment, the clamp includes a clamping plate 22 and a buffer plate 23. The clamping plate 22 is disposed at the output end of the clamping drive device 21, and the buffer plate 23 is disposed on the side of the clamping plate 22 away from the clamping drive device 21.

[0069] During clamping, the buffer plate 23 prevents the clamping plate 22 from directly contacting the air duct, reducing scratches, indentations, or other forms of damage to the air duct surface caused by clamping. When the clamping drive device 21 drives the clamping plate 22 to clamp the air duct, the buffer plate 23 absorbs the impact force generated by rapid clamping or releasing actions, thereby reducing impact damage to the air duct. In practical applications, the presence of the buffer plate 23 increases the contact area between the clamping mechanism 2 and the air duct, improves clamping stability, and ensures that the air duct will not shift due to insecure clamping during the shaping process.

[0070] In practical applications, the buffer plate 23 can be made of rubber to reduce the damage of the clamp plate 22 to the air duct.

[0071] Example 4

[0072] This embodiment is an improvement on embodiment 3.

[0073] like Figures 1-7 As shown, in this embodiment, the main body 1 is also provided with a lifting mechanism 4. The lifting mechanism 4 includes a lifting drive device 41 and a lifting seat 42. The lifting drive device 41 is fixed on the main body 1, the lifting seat 42 is disposed at the output end of the lifting drive device 41, and the clamping mechanism 2 is disposed on the lifting seat 42.

[0074] In practical use, the lifting drive device 41 drives the lifting seat 42 to move vertically to adjust the height of the clamping mechanism 2 relative to the air duct placement position 11. Through the lifting mechanism 4, the height of the clamping mechanism 2 can be adjusted according to the actual height of the air duct, ensuring that the clamping mechanism 2 can adapt to air ducts of different sizes. The lifting mechanism 4 allows the clamping mechanism 2 to move vertically, increasing operational flexibility and making the shaping process smoother. Furthermore, the automated control of the lifting mechanism 4 reduces manual operation, improving production efficiency and operational safety.

[0075] In practical applications, the lifting drive device 41 can be a servo motor or a stepper motor, which provides precise control and strong torque to ensure the smooth movement of the lifting platform 42. Alternatively, the servo motor can be connected to the lifting platform 42 via a transmission mechanism, allowing the lifting platform 42 to rise and fall under the motor's drive. Alternatively, the lifting drive device 41 can be a cylinder, with the piston rod of the cylinder driving the lifting platform 42 to rise and fall.

[0076] Example 5

[0077] This embodiment is an improvement on embodiment 1.

[0078] like Figures 1-7 As shown, in this embodiment, two shaping drive devices 31 are provided, and the two shaping drive devices 31 are symmetrical about the center of gravity of the shaping plate 32. The output ends of both shaping drive devices 31 are connected to the shaping plate 32. A shaping head 33 is provided on the shaping plate 32, and the shaping head 33 is located on the side of the shaping plate 32 away from the shaping drive device 31.

[0079] By symmetrically arranging two shaping drive devices 31, it can be ensured that the shaping plate 32 is subjected to uniform force during the shaping process, avoiding skewing of the shaping plate 32 or uneven shaping of the air duct due to unbalanced driving forces. Symmetrical drive devices can improve shaping accuracy, ensuring that the dimensions and shape of the duct after shaping meet design requirements. Furthermore, uniform shaping force can reduce the risk of damage to the air duct during the shaping process, improving its integrity and durability. In this embodiment, the shaping head 33 connects to the air duct, avoiding direct contact between the shaping plate 32 and the air duct. In actual use, the shaping head 33 can be made of rubber to prevent damage to the air duct during the shaping process.

[0080] More preferably, in this embodiment, the main body 1 is further provided with an angle adjustment mechanism 5, the angle adjustment mechanism 5 including an angle adjustment drive device 51 and an angle adjustment plate 52, the angle adjustment drive device 51 is fixed on the main body 1, and the axis of the output end of the angle adjustment drive device 51 is perpendicular to the horizontal plane; the angle adjustment plate 52 is disposed on the output end of the angle adjustment drive device 51, and one side of the angle adjustment plate 52 is hinged to the main body 1, and the shaping mechanism 3 is disposed on the angle adjustment plate 52.

[0081] In this embodiment, the angle adjustment drive device 51 can adjust the angle of the angle adjustment plate 52 relative to the main body 1 frame. This angle can be the angle between the plane where the angle adjustment plate 52 is located and the horizontal plane. By changing the position of the angle adjustment plate 52 through the angle adjustment drive device 51, the angle of the shaping plate 32 of the shaping mechanism 3 can be changed, thereby adapting to the shaping of different air ducts. The shaping mechanism 3 is set on the angle adjustment plate 52 and can change the shaping angle as the angle adjustment plate 52 rotates. The air duct shaping process of the air duct shaping mechanism 3 in this embodiment is as follows: After the air duct is formed and produced, the air duct is picked up by a robot and placed on the air duct placement position 11.

[0082] The angle adjustment drive device 51 adjusts the angle adjustment plate 52 to an appropriate position, so that the shaping mechanism 3 can precisely shape the air duct. The two shaping drive devices 31 are activated simultaneously, symmetrically driving the shaping plate 32 to move closer to the air duct placement position 11 to shape the air duct.

[0083] This embodiment adds an angle adjustment mechanism 5 to the main body 1, enabling the shaping mechanism 3 to shape the air duct at a precise angle, thus improving the accuracy and quality of the shaping. It can also adapt to air ducts of different shapes and sizes, improving the versatility and applicability of the shaping structure. The angle adjustment mechanism 5 provides more operational dimensions, making the shaping process more flexible and allowing adjustments based on the specific needs of the air duct.

[0084] Example 6

[0085] This embodiment is an improvement on embodiment 1.

[0086] like Figures 1-7 As shown, in this embodiment, a pressure sensor 34 is provided on the shaping head 33, and the pressure sensor 34 is located on the side of the shaping head 33 opposite to the shaping drive device 31.

[0087] Pressure sensor 34 is used to monitor the pressure applied to the air duct by the shaping head 33 in real time.

[0088] The sensor data can be fed back to the control system of the mechanism. The control system adjusts the force of the shaping drive device 31 based on the received data to ensure the uniformity and accuracy of pressure during the shaping process. By controlling the shaping pressure, the risk of damage to the air duct during the shaping process can be reduced, improving the integrity and durability of the air duct. Precise pressure control can reduce errors and rework during the shaping process, thereby improving production efficiency.

[0089] In this embodiment, the duct shaping process is as follows: After the duct is formed, a robotic arm picks it up and places it on the duct placement position 11. The shaping drive device 31 is activated, driving the shaping plate 32 to approach the duct placement position 11 to shape the duct. During shaping, the pressure sensor 34 monitors the pressure and feeds the data back to the control system. The control system adjusts the force of the shaping drive device 31 based on the feedback data from the pressure sensor 34 to ensure the uniformity and accuracy of the pressure during the shaping process.

[0090] The pressure sensor 34 used in this embodiment can be a piezoelectric pressure sensor 34. A piezoelectric pressure sensor 34 utilizes the principle that piezoelectric materials (such as quartz crystals) generate electrical charges when subjected to pressure. When pressure is applied to the piezoelectric material, the electric field inside the material changes, thereby generating charges on the surface of the material. These charges can be converted into voltage or current signals and output through a circuit. This allows for the measurement of the pressure between the shaping plate 32 and the air duct.

[0091] Example 7

[0092] This embodiment is an improvement on embodiment 1.

[0093] like Figures 1-7 As shown, in this embodiment, a deformation detection sensor 12 is provided on the edge of the air duct placement position 11, and the deformation detection sensor 12 is positioned facing the air duct placement position 11.

[0094] The deformation detection sensor 12 in this embodiment is used to monitor the deformation of the air duct in the placement position in real time.

[0095] Sensors can detect changes in the dimensions of the air duct before and after reshaping, ensuring that the reshaping effect meets expectations.

[0096] During the duct shaping process, the control system adjusts the force of the shaping drive device 31 and the position of the shaping plate 32 based on the feedback data from the deformation detection sensor 12, ensuring the uniformity and accuracy of pressure during the shaping process. Real-time monitoring can avoid duct damage caused by over-shaping, improving the integrity and durability of the duct.

[0097] The deformation detection sensor 12 provided in this embodiment can be a photoelectric sensor. Photoelectric sensors utilize the photoelectric effect to detect shape changes in objects, making them suitable for non-contact measurement and avoiding additional pressure on the air duct. In practical applications, multiple deformation detection sensors 12 can be placed at different locations on the air duct placement position 11 to obtain overall deformation data of the air duct, improving the accuracy and reliability of the measurement. When using multiple sensors, the data from each sensor needs to be fused and processed to obtain more comprehensive deformation information.

[0098] Example 8

[0099] like Figures 1-7 As shown, this embodiment provides an air duct production system, including a robotic arm and the air duct shaping mechanism 3 as described above.

[0100] Specifically, the robotic arm includes a robotic arm, an end effector (for gripping the air duct), a control system, and a drive system. The robotic arm is used to grip newly produced air ducts and move them to the air duct placement position 11 of the air duct shaping mechanism 3.

[0101] More preferably, the duct production system also includes a vision system, which identifies and inspects the location, size, and shape of the ducts to ensure the robot accurately grasps and places them. It may also include a conveyor line that transports newly produced ducts from the production line to the robot's grasping position. The conveyor line includes conveyor belts, rollers, guides, and a control system.

[0102] The air duct production system provided in this application, by integrating a robotic arm and an air duct shaping mechanism 3, automates air duct production, reduces manual intervention, and improves production efficiency. Furthermore, the system can adapt to the shaping of air ducts of different sizes and shapes, exhibiting high flexibility and adaptability.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings. In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0104] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "above" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways, and the spatial relative descriptions used herein will be interpreted accordingly.

[0105] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0106] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
