[0025] As Figures 1-4As shown, this embodiment proposes a fan coil unit assembly device, including a frame 1, and two sets of side plate clamping devices and two sets of enclosure plate clamping devices disposed on the frame 1. The two sets of side plate clamping devices are disposed opposite to each other on both sides of the frame 1. Each side plate clamping device includes a rotating shaft assembly 21, a first driving component 22 for axially moving the rotating shaft assembly 21, and a mold plate 23 disposed at the inner end of the rotating shaft assembly 21. A chuck 24 for clamping the volute side plate is disposed on the outer side of the mold plate 23. The enclosure plate clamping device is disposed on a front and rear sliding joint, and includes a longitudinally movable component relative to the rotating shaft assembly 21.

[0026] The device includes a second driving component 31, a clamping wheel 32, and a guide component 33 located on the output end of the second driving component 31. During installation, the first driving component 22 drives the mold plate 23 and the chuck 24 to move below the enclosure clamping device. The second driving component 31 in the enclosure clamping device drives the clamping wheel 32 and the guide component 33 to move longitudinally until the clamping wheel 32 presses against the edge of the volute enclosure plate and the guide component 33 presses against the mold plate 23.

[0027] This solution achieves automated control of the coil fan assembly process by setting up a frame 1, a side plate clamping device, and a surrounding plate clamping device. The side plate clamping device, through the cooperation of the rotating shaft assembly 21 and the first drive component 22, can accurately clamp the volute side plate; the surrounding plate clamping device, through the cooperation of the second drive component 31 and the clamping wheel 32, can effectively clamp the edge of the volute surrounding plate. Specifically, the volute side plate is first fixed on the chuck 24 on the outside of the mold plate 23. Then, the impeller is initially positioned between the two volute side plates. Then, the first drive component 22 drives the mold plate 23, the chuck 24, and the volute side plates on them to move axially closer and place them below the surrounding plate clamping device. Then, the second drive component 31 in the surrounding plate clamping device drives the clamping wheel 32 and the guide component 33 to move longitudinally until the clamping wheel 32 is pressed against the edge of the volute surrounding plate and the guide component 33 is pressed against the mold plate 23. When the rotating shaft assembly 21 drives the mold plate 23 and chuck 24 to rotate, the guide component 33 always conforms to the mold plate 23 for contouring. At the same time, the clamping roller 32 clamps the edge of the volute casing plate to shape the volute casing plate. During this process, the edge of the volute casing plate needs to be manually and gradually fixed to the volute casing side plate, such as by riveting or spot welding, thereby realizing the automated installation of the coil fan. This design not only reduces manual operation and improves production efficiency, but also improves the quality of product assembly through the precise control of the mechanical device.

[0028] Further, the application also proposes that the rotating shaft assemblies 21 of the two side plate pressing devices are connected to the same rotating drive mechanism, the output end of the rotating drive mechanism is connected to the rotating seat 25 on the rotating shaft assembly 21, and the rotating seat 25 and the rotating shaft assembly 21 are axially movable relative to each other. Specifically, the rotating drive mechanism is connected to the rotating seat 25 on the rotating shaft assembly 21 through its output end, so that the rotating shaft assemblies 21 of the two side plate pressing devices can realize synchronous rotation. At the same time, the circumferential linkage design of the rotating seat 25 and the rotating shaft assembly 21 allows the rotating shaft assembly 21 to move relatively in the axial direction, thereby realizing the adjustment of the axial position while maintaining synchronous rotation. This design solves the technical problem of needing to control rotation and axial movement simultaneously during assembly, improving the accuracy and efficiency of assembly. As a preferred embodiment, the rotating drive mechanism can be driven by a motor, and its output end is connected to the rotating seat 25 through a shaft coupling, ensuring the stability and accuracy of rotation. The rotating seat 25 can be designed to be connected to the rotating shaft assembly 21 through a sliding bearing, making the movement of the rotating shaft assembly 21 in the axial direction more smooth. In addition, the axial movement of the rotating shaft assembly 21 can be realized by a gas cylinder or other linear driving device, ensuring accurate control of movement. Thus, through the connection design of the rotating drive mechanism and the rotating shaft assembly 21, the application realizes the synchronous control of rotation and axial movement, solving the problem of low efficiency and difficult control of assembly quality in the prior art. Compared with the prior art, the technical scheme of the application not only improves the accuracy and efficiency of assembly, but also reduces the complexity of manual operation, and is suitable for mass production.

[0029] Further, the application also proposes that the first driving component 22 is constructed as a gas cylinder, and the end of the first driving component 22

[0030] connected through a shaft coupling with built-in bearings. Specifically, the gas cylinder, as a common driving device, can provide stable axial driving force, ensuring that the mold plate 23 and the chuck 24 can be accurately moved to the bottom of the surrounding plate pressing device. The connection method of the shaft coupling with built-in bearings not only ensures the stability and accuracy of the rotating shaft assembly 21 during movement, but also improves the control accuracy and efficiency during assembly. In addition, this connection method can avoid affecting the gas cylinder shaft when the rotating shaft assembly 21 rotates, thereby ensuring the smooth progress of the entire assembly process. As a preferred embodiment, the gas cylinder can control its extension and retraction through a solenoid valve to realize accurate control of the mold plate 23 and the chuck 24. The built-in bearings in the shaft coupling can adopt ball bearings or sliding bearings to adapt to different working environments and load requirements. Thus, this structural design not only solves the technical problems of the driving method and connection structure of the first driving component 22 in the side plate pressing device, but also significantly improves the performance and reliability of the assembly equipment.

[0031] Further, the application also proposes that the guide component 33 is designed as a guide shaft, and the pressing wheel 32 is arranged on the guide shaft or rotates synchronously with the guide shaft; the outer contour of the mold plate 23 is designed to be adapted to the shape of the volute side plate and slightly larger than the volute side plate, and when the pressing wheel 32 is pressed on the edge of the volute surrounding plate, the guide shaft is pressed on the mold plate 23. Specifically, the guide shaft is designed to be in close contact with the outer contour of the mold plate 23, so that when the pressing wheel 32 is pressed on the edge of the volute surrounding plate, the guide shaft can effectively press on the mold plate 23. This design ensures the close fit of the volute side plate and the surrounding plate through the cooperation of the guide shaft and the pressing wheel 32. The diameter of the guide shaft is smaller than the pressing wheel 32 fitted thereon, and during processing, the guide shaft is in contact with the outer contour of the mold plate 23, while the pressing wheel 32 is pressed on the edge of the volute surrounding plate, so that the guide shaft is profiled based on the outer contour of the mold plate 23, and the pressing wheel 32 moves along the same track and shapes the edge of the volute surrounding plate. As a preferred embodiment, the guide shaft can be manufactured by machining to ensure the accuracy of its diameter and shape. The pressing wheel 32 can be mounted on the guide shaft through bearings to enable free rotation, thereby reducing friction and improving pressing efficiency during pressing. The outer contour of the mold plate 23 is designed to be adapted to the shape of the volute side plate and slightly larger than the volute side plate, which can ensure that the mold plate 23 can completely cover the volute side plate during assembly, and under the action of the pressing wheel 32 and the guide shaft, the volute side plate and the surrounding plate can be accurately pressed. Therefore, through the design of the guide shaft and the pressing wheel 32, the application solves the pressing problem of the volute side plate and the surrounding plate, and improves the assembly accuracy and efficiency. Compared with the prior art, the technical scheme of the application not only reduces manual operation during assembly, but also ensures the consistency and stability of assembly through the mechanical pressing device, thereby improving the quality and production efficiency of the product.

[0032] Further, the application also proposes that the front and rear moving pair includes a front and rear moving track 41 arranged on the support of the rack 1, a moving seat 42 arranged on the front and rear moving track 41, and a driving motor 43 driving the moving seat 42 to move along the front and rear moving track 41, and the surrounding plate pressing device is arranged on the moving seat 42. The front and rear moving track 41 can adopt a linear guide rail or a sliding rail, and the moving seat 42 is matched with the front and rear moving track 41 through a sliding block or a roller to realize stable movement. The driving motor 43 can adopt a servo motor or a stepping motor, which is connected with the moving seat 42 through a transmission mechanism such as a gear or a belt to accurately control the position of the moving seat 42. The surrounding plate pressing device can include a cylinder-driven pressing wheel 32 and a guide component 33, the pressing wheel 32 is used to

[0033] The guiding component 33 is used to ensure the correct alignment of the pressing wheel 32 and the mold plate 23. Specifically, the design of the front and rear moving pair enables the surrounding plate pressing device to adjust the position as needed, thereby improving the flexibility and efficiency of assembly and reducing the need for manual operation. Through the mechanical moving device, the position and force during assembly can be more accurately controlled, thereby improving the product assembly quality and solving the problem of difficult control of assembly quality. Thus, through the design of the front and rear moving pair, the surrounding plate pressing device is realized on the rack 1, so that the pressing wheel 32 can be rolled on the edge of the surrounding plate of the volute.

[0034] Further, the present application also proposes that the surrounding plate pressing device comprises a mounting frame 34 arranged on the moving seat 42, a second driving component 31 arranged on the mounting frame 34, and a pressing wheel 32 and a guiding component 33 arranged on the output end of the second driving component 31; the second driving component 31 is constructed as a pneumatic cylinder. Specifically, the mounting frame 34 is fixed on the moving seat 42, which provides a mounting basis for the second driving component 31. The second driving component 31, i.e. the pneumatic cylinder, drives the pressing wheel 32 and the guiding component 33 to move longitudinally through the piston rod of its output end. The pressing wheel 32 is used to press the edge of the surrounding plate of the volute, and the guiding component 33 ensures the accuracy of the movement path of the pressing wheel 32, thereby ensuring the precision and stability during assembly. As a preferred embodiment, the pneumatic cylinder can control its extension and retraction through an electromagnetic valve, realizing accurate control of the pressing wheel 32 and the guiding component 33. In addition, the guiding component 33 can be designed as a guide shaft, and the pressing wheel 32 is rotatably arranged on the guide shaft or synchronously rotatable with the guide shaft to adapt to different assembly requirements. Thus, the surrounding plate pressing device drives the pressing wheel 32 and the guiding component 33 through the pneumatic cylinder, realizing accurate pressing of the surrounding plate of the volute. This structure not only reduces the number of workers and improves production efficiency, but also significantly improves the quality control of product assembly. Compared with the prior art, the technical scheme of the present application effectively solves the problems of many workers, low production efficiency and difficult control of assembly quality in manual assembly through the mechanical pressing device.

Thus, the design of the chuck 24 enables accurate control of the opening and closing of the clamping claws 242 during assembly, thereby improving the assembly accuracy and efficiency. Compared with the prior art, the present application drives the clamping claws 242 to rotate through the axial movement of the rotating shaft assembly 21, thereby achieving accurate control of the opening and closing of the clamping claws 242, solving the technical problem of controlling the opening and closing of the clamping claws 242 during assembly of the chuck 24, and improving the assembly efficiency and accuracy.
