[0033] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0034] Example

[0035] like Figures 1 to 9 As shown, the present invention includes an assembly platform 1, on which a laser-assisted mechanism 2, a wheel track adjustment mechanism 3, a roller mechanism 5, and a foot adjustment mechanism 4 are provided. The laser-assisted mechanism 2 is used to emit a laser into a horizontal plane, the wheel track adjustment mechanism 3 is used to support the air inlet hood of the ventilator, the roller mechanism 5 is used to rotate the main body section of the ventilator circumferentially, and the foot adjustment mechanism 4 is used to limit the main body section of the ventilator, and the height of the foot adjustment mechanism 4 is adjustable.

[0036] In existing technologies, when assembling ventilation fans, the components, including the air inlet hood, front silencer, main unit, impeller, and rear silencer, vary in size due to differences in the components among different fan models. This makes existing fan assembly tables unsuitable for different fan models. Therefore, this technical solution incorporates a laser-assisted mechanism 2, a wheel track adjustment mechanism 3, a roller mechanism 5, and a foot adjustment mechanism 4 on the assembly table 1. The laser-assisted mechanism 2 emits a laser beam horizontally, guiding the installation of the fan's base, lifting lugs, and motor control box. Each component is installed in its designated position, thereby improving the installation accuracy of the ventilator. The wheel track adjustment mechanism 3 is used to install different models of air inlet hoods. The roller mechanism 5 can support the main unit section of air inlet hoods of different lengths and diameters. At the same time, during the support of the air inlet hood, it can also facilitate the circumferential rotation of the air inlet hood so that the air inlet hood can be precisely matched with the main unit section. The foot adjustment mechanism 4 can support the main unit section of the ventilator, improving the stability of the support for the main unit section. At the same time, the height of the foot adjustment mechanism 4 can be adjusted to meet the support needs of main unit sections of different sizes.

[0037] The laser-assisted mechanism 2 includes a support frame 6, a connecting plate 7, an adjustment platform 10, and several laser emitters 11. The support frame 6 is vertically fixed on the assembly platform 1. The connecting plate 7 is fixed on the side wall of the support frame 6. The adjustment platform 10 is connected to the connecting plate 7 and the laser emitters 11 respectively. The adjustment platform 10 is used to adjust the position of each laser emitter 11 in the horizontal and vertical directions.

[0038] In this embodiment, to ensure that the laser emitted by the laser auxiliary mechanism 2 is horizontal, the laser auxiliary mechanism 2 includes a support frame 6, a connecting plate 7, an adjustment platform 10, and several laser emitters 11. The support frame 6 is vertical, and the connecting plate 7 connects the adjustment platform 10 and the laser emitters 11 to the support frame 6. In order to ensure that the position of the laser emitters 11 can be adjusted to meet the needs of assembling ventilators of different sizes, the adjustment platform 10 is provided. The adjustment platform 10 can not only adjust the vertical position of the laser emitters 11, but also adjust the horizontal position of the laser emitters 11, thus improving the versatility of the laser auxiliary mechanism 2.

[0039] The adjustment platform 10 includes a vertical adjustment unit and a horizontal adjustment unit. The vertical adjustment unit includes a first drive mechanism 8, a first slide table, and a slide plate 9. The first slide table is connected to a connecting plate 7, and the slide plate 9 is slidably connected to the first slide table. The first drive mechanism 8 is connected to the slide plate 9. The horizontal adjustment unit is fixed on the slide plate 9. One laser emitter 11 is connected to the slide plate 9, and the other laser emitters 11 are movably connected to the horizontal adjustment unit.

[0040] In order to meet the needs of adjusting the vertical and horizontal positions of the laser emitter 11, the adjustment platform 10 includes a vertical adjustment unit and a horizontal adjustment unit. The vertical adjustment unit includes a first drive mechanism 8, a first slide, and a slide plate 9. The first drive mechanism 8 is a cylinder or a hydraulic cylinder. When it works, it can drive the slide plate 9 on the first slide to move in the vertical direction, thereby realizing the adjustment of the height of the slide plate 9 in the vertical direction, and thus realizing the adjustment of the vertical position of each laser emitter 11.

[0041] The horizontal adjustment unit includes a housing 12 and a second drive mechanism 18. The housing 12 is connected to the slide plate 9. Two pulleys 13 are provided on the inner bottom of the housing 12. A transmission belt 16 is fitted on the pulleys 13. The second drive mechanism 18 is connected to one of the pulleys 13. A movable plate 14 is also provided on the transmission belt 16. The laser emitter 11 is located on the movable plate 14. An opening is provided on one side of the housing 12.

[0042] In this embodiment, to enable adjustment of the horizontal position of some laser emitters 11, a horizontal adjustment unit is provided, including a housing 12 and a second drive mechanism 18. The second drive mechanism 18 is a motor, which drives one of the pulleys 13 to rotate. When the pulley 13 rotates, it drives the conveyor belt 16 to rotate synchronously. Two movable plates 14 are provided on the conveyor belt 16. One movable plate 14 is connected to one side of the conveyor belt 16, and the other movable plate 14 is connected to the other side of the conveyor belt 16. Thus, when the second drive mechanism 18 drives the pulley 13 to rotate clockwise, the two movable plates 14 can move away from each other, increasing the distance between the two movable plates 14. When the second drive mechanism 18 drives the pulley 13 to rotate counterclockwise, the two movable plates 14 will move closer together, shortening the distance between the two movable plates 14, thereby realizing the adjustment of the horizontal position of the two laser emitters 11 on the movable plate 14.

[0043] The inner bottom of the housing 12 is also provided with two protrusions, and two pulleys 13 are located between the two protrusions. A guide rod 15 is also provided between the protrusions, and the guide rod 15 passes through the movable plate 14.

[0044] In this embodiment, in order to ensure that the movable plate 14 can move smoothly in the horizontal direction within the housing 12, a guide rod 15 is provided between the two protrusions inside the housing 12. The guide rod 15 is distributed along the movable plate 14, and the movable plate 14 is sleeved on the guide rod 15. In this way, when the conveyor belt 16 drives the movable plate 14 to move in the horizontal direction, the guide rod 15 can ensure that the movable plate 14 moves stably in the straight line direction.

[0045] The wheel track adjustment mechanism 3 includes a first base plate 23 and two first support plates 19. The first base plate 23 is fixed to the top of the assembly platform 1. The top of the first base plate 23 is provided with two sets of adjustment components. Each adjustment component includes two protrusions 22 and a rotating rod 21 is provided between the protrusions 22. The two rotating rods 21 are respectively connected to the two first support plates 19 by threads. The first base plate 23 is also provided with two first slide rails 24. The bottom of the first support plate 19 is slidably connected to the first slide rails 24. The first support plate 19 is also provided with two first rotating wheels 32.

[0046] In this embodiment, in order to support the air inlet hoods of ventilators of different sizes, the wheel spacing adjustment mechanism 3 includes a first base plate 23 and two first support plates 19. When it is necessary to adjust the distance between the two first support plates 19, the two first support plates 19 slide on the first slide rail 24 by rotating the rotating rod 21, thereby changing the distance between the two first support plates 19 so that the first rotating wheel 32 on the first support plate 19 can support air inlet hoods of different diameters. At the same time, in order to facilitate the rotation of the rotating rod 21, a rotating handle 20 is also provided on the rotating rod 21 to facilitate the rotation of the rotating rod 21.

[0047] The roller mechanism 5 includes a second base plate 25 and two sets of support units. The second base plate 25 is fixed to the top of the assembly table 1. The top of the second base plate 25 is provided with a second slide rail 26. The second slide rail 26 is provided with a first slider 27. The support unit includes a first rectangular tube 28, a support block 29, a second rectangular tube 30, and a second support plate 31. The first rectangular tube 28 is fixed to the first slider 27. The support block 29 is located on the top of the first rectangular tube 28. The second rectangular tube 30 is fixed to the top of the support block 29. The second support plate 31 is fixed to the top of the second rectangular tube 30. The top of the second support plate 31 is also provided with a second rotating wheel.

[0048] In this embodiment, to ensure that the roller mechanism 5 can support the main body sections of the ventilator of different lengths, the roller mechanism 5 includes a second base plate 25 and two sets of support units. The support units can slide on the second slide rail 26 via the first slider 27, thereby adjusting the distance between the two support units and satisfying the support of main body sections of different lengths. At the same time, in order to improve the stability and weight of the support unit, the support unit includes a first rectangular tube 28, a support block 29, and a second rectangular tube 30. The use of the first and second rectangular tubes can not only reduce the overall weight of the support unit, but also improve the stability of the support unit. When assembling the main body section of the ventilator, the main body section is first lifted and placed flat on the second rotating wheel on the second support plate 31. The second rotating wheel supports the main body section, so that the main body section can rotate around its circumference under the action of the second rotating wheel, and the position of the main body section can be adjusted.

[0049] The foot adjustment mechanism 4 includes a column 35, a third drive mechanism 33, and a third support plate 34. The column 35 is fixed to the top of the assembly table 1. A second slide is provided on the column 35, and a second slider is provided on the second slide. The second slider is slidably connected to the second slide. The third drive mechanism 33 is connected to the second slider. The third support plate 34 is connected to the second slider. A support platform 36 is provided on the top of the third support plate 34, and an arc-shaped groove is provided on the support platform 36.

[0050] In this embodiment, to prevent the main unit section from detaching from the second rotating wheel, a foot adjustment mechanism 4 is also provided, including a column 35, a third drive mechanism 33, and a third support plate 34. When assembling the main unit section of the ventilator, a lifting device is used to place the main unit section on the arc-shaped groove provided on the third support plate 34. The foot adjustment mechanisms 4 on both sides of the main unit section constrain both sides of the main unit section, thereby preventing the main unit section from detaching from the second rotating wheel. At the same time, in order to meet the requirement of limiting the main unit section of different models, a third drive mechanism 33 is also provided. The third drive mechanism 33 is a cylinder or hydraulic cylinder, which can drive the second slider to move in the vertical direction when it is working, thereby changing the height of the support platform 36 in the vertical direction, so as to meet the requirement of limiting the main unit section of different sizes.

[0051] The support platform 36 has an arc-shaped groove with a recess. The recess contains several first rotating shafts 37, each with a support wheel 39. Each support wheel 39 has several protruding posts 38 evenly distributed around its circumference. The recess also contains an equal number of airbags 42 and compression plates 40 as the support wheels 39. The compression plates 40 are located below the support wheels 39 and have a second rotating shaft movably connected to the inner wall of the recess, allowing the compression plates 40 to rotate within the recess. One end of the compression plate 40 is located on one side of the airbag 42, and the other end is located between two adjacent protruding posts 38. The recess also contains a torsion spring 41 connected to the compression plate 40, located near the connection between the airbag 42 and the compression plate 40. The airbag 42 also has an exhaust port facing the support wheel 39.

[0052] Since the function of the support platform 36 is to constrain the main unit segment and prevent it from falling off the second rotating wheel, and in this embodiment, to reduce wear between the main unit segment and the arc-shaped groove of the support platform 36 during rotation, a groove is provided in the arc-shaped groove of the support platform 36, and a support wheel 39 is provided in the groove. When the main unit segment is placed in the arc-shaped groove on the support platform 36, the protrusion 38 on the support wheel 39 supports the main unit segment, thereby reducing the contact area between the support platform 36 and the main unit segment, and thus reducing wear during the rotation of the main unit segment; at the same time, when the main unit segment is rotated, the main unit segment will drive the support wheel 39 to rotate under the action of friction, and when the protrusion 38 rotates to the upper end face of the extrusion plate 40, it will drive the extrusion plate 40 to rotate. During the rotation, the extrusion plate 40 will squeeze the airbag 42, compressing the airbag 42. 2. The internal air acts on the support wheel 39 through the exhaust port, thereby achieving the purpose of cooling the support wheel 39 and preventing the main unit from heating up due to friction during rotation on the support wheel 39, thus providing a certain degree of protection for the main unit and the support wheel 39. When the protrusion 38 drives the extrusion plate 40 to rotate to its maximum position, the protrusion 38 will remove the force on the extrusion plate 40. At this time, the extrusion plate 40 will rotate back to its initial state under the action of the torsion spring 41. During this process, the air bag 42 will stretch the air bag 42, creating a negative pressure inside the air bag 42, drawing in fresh air from the outside. When the next protrusion 38 rotates to the extrusion plate 40, it will continue to rotate the extrusion plate 40, realizing the reciprocating extrusion of the air bag 42, achieving continuous air blowing and cooling during the rotation of the main unit, thus providing a certain degree of protection for the main unit.

[0053] As is easily understood, the mining ventilation fan assembly device based on the Industrial Internet of Things (IIoT) provided in this solution essentially integrates the physical assembly device provided above into the IIoT assembly process and procedures. By utilizing the data collection, analysis, and intelligent decision-making provided by the IIoT, the ventilation fan assembly process is made digital, intelligent, and highly flexible, thereby achieving intelligent manufacturing of ventilation fan units.

[0054] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. 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.
