Description

Technical Field

[0001] This application belongs to the field of wind turbine blade manufacturing technology, specifically relating to a wind turbine blade adhesive application device with asymmetric and automatically adjustable adhesive type. Background Technology

[0002] Currently, my country is placing increasing emphasis on the wind power industry, which undoubtedly places stricter demands on the production efficiency and quality of wind turbine blades. In the production process of wind turbine blades, bonding the two halves of the blade with adhesive is a crucial step. In particular, the bonding quality of the web, as the main load-bearing component of the wind turbine blade, directly affects the structural strength of the entire blade. Currently, the adhesive application process for wind turbine blades mainly relies on manual operation, and the skill level and number of workers have a decisive impact on the efficiency and quality of adhesive application. However, manually controlling the thickness and width of the adhesive often leads to uneven or excessive application, which not only affects the quality of adhesive application but also wastes raw materials. Therefore, developing an advanced device that can automatically adjust the adhesive application method according to the adhesive application process requirements is of paramount importance for improving adhesive application efficiency and quality.

[0003] The patent application number 202311729625.7, entitled "A Wind Turbine Blade Adhesive Application Device with Automatic Adhesive Adjustment Based on Adhesive Application Process," comprises an adhesive application box, an adhesive width and thickness adjustment mechanism, and a length measurement feedback control component. The length measurement feedback control component controls the movement of the adhesive width and thickness adjustment mechanism by measuring the travel distance of the adhesive application device, thereby adjusting the lateral width and vertical thickness of the adhesive outlet to meet the required adhesive size. However, the length measurement feedback control used in this device cannot adjust the adhesive width in real time, resulting in a deviation between the applied adhesive surface and the actual contour of the blade bonding surface. Therefore, the adhesive size cannot accurately match the adhesive application process requirements.

[0004] The patent application number 202411456446.5, entitled "A Wind Turbine Blade Glue Coating Device," comprises a glue tank, two glue width adjustment plates, one glue thickness adjustment plate, and a control unit. The control unit controls the movement of the glue width and thickness adjustment plates to adjust the lateral width and vertical thickness of the glue outlet, thereby ensuring the glue size meets requirements and significantly improving the efficiency of wind turbine blade glue application. Simultaneously, it controls the amount of glue applied, saving on the cost of wind turbine blade glue application. This patent structure includes a glue box, a scraper, two side plates, and a control device. The scraper can move vertically to change the glue outlet thickness, and the side plates can move symmetrically left and right to change the glue outlet width. However, the scraper shape is fixed, and the side plates must move symmetrically, resulting in a relatively limited glue application size, which cannot meet the needs of various glue types in actual production.

[0024] To make the objectives, technical solutions and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] See Figure 1 , Figure 1 This is a schematic diagram of an embodiment of the asymmetric, automatically adjustable adhesive applicator for wind turbine blades according to this application. The device includes an adhesive applicator box 1, a drive assembly 2, an adjustment assembly 3, a base plate 4, a main control assembly 5, a battery 6, a housing 7, a length measuring assembly 8, and a vision detection assembly 9. The base plate 4 is the main load-bearing component, the adhesive applicator box 1 is fixedly connected to the bottom of the base plate 4, and the adjustment assembly 3 is disposed on the outside of the adhesive applicator box 1. The drive assembly 2 is installed on the top of the base plate 4 and connected to the adjustment assembly 3. A frame plate 51 is provided on the rear side of the drive assembly 2, and the main control assembly 5, which controls the start and stop of the drive assembly 2, is installed on the frame plate 51. A battery box 6 is installed on the side of the frame plate 51. A housing 7 is fitted on the upper side of the base plate 4 to cover the drive assembly 2 and the main control assembly 5. A length measuring assembly 8 is installed below the rear end of the base plate 4. A vision detection assembly 9 for capturing the adhesive application status is installed in the base plate 4 between the length measuring assembly 8 and the adjustment assembly 3. The housing 7 has an injection hole 71 corresponding to the injection tube 12, and two handles 72 are provided on the top of the housing 7. The handle 72 in the above design facilitates gripping the entire device. The length measuring component 8 can measure the specific moving distance of the glue application box 1. The vision inspection component 9 can capture the glue application process at the glue outlet 14 and use this feedback to control the drive component 2, which in turn drives the adjustment component 3 to adjust the inner working surface of the glue outlet 14 in real time. This ensures that the working surface dynamically conforms to the outer boundary line of the glue application area during the glue application process, guaranteeing that the shape of the applied adhesive accurately matches the actual contour of the blade bonding surface.

[0027] See Figure 2The drive assembly 2 includes a width cylinder 21 and a thickness cylinder 22. The thickness cylinder 22 is vertically fixed to the middle of the substrate 4 via a first cylinder seat 23. The telescopic rod of the thickness cylinder 22 passes through a through hole in the substrate 4 and is connected to a first connecting seat 37. The width cylinder 21, which is parallel to the guide shaft 34, is connected to a second cylinder seat 24 located on both sides of the substrate 4. The telescopic rod of the width cylinder 21 is connected to a sliding seat 25. The substrate 4 on both sides of the thickness cylinder 22 has a strip-shaped slot 41 parallel to the guide shaft 34. The support rod 26 below the sliding seat 25 passes through the strip-shaped slot 41 and is connected to the side end of the sliding bushing 33. In the above design, the thickness cylinder 22 can be connected to the first connecting seat 37 via the telescopic rod end, thereby driving the thickness adjustment plate 32 to rise and fall to adjust the thickness of the dispensing nozzle 14. The telescopic rod end of the width electric cylinder 21 can drive the width adjustment plate 31 to move back and forth along the guide shaft 34 through the sliding seat 25, the support rod 26 and the sliding bushing 33 to adjust the width of the dispensing port 14.

[0028] See Figure 3 The adjustment component 3 includes a width adjustment plate 31 and a thickness adjustment plate 32. The width adjustment plate 31 is fixed to both sides of the dispensing port 14. A sliding bushing 33 is connected to the upper end of the width adjustment plate 31. The sliding bushing 33 is sleeved on a guide shaft 34 that is parallel to the width direction of the substrate 4. The middle part of the guide shaft 34 is fixed to the lower part of the substrate 4 through a bearing 35. The thickness adjustment plate 32 is disposed in the opening 42 above the dispensing port 14. The two sides of the thickness adjustment plate 32 are connected to the width adjustment plate 31 through flexible adhesive plates 36. A first connecting seat 37 is provided at the upper middle part of the thickness adjustment plate 32. In the above design, the width adjustment plate 31 can be moved back and forth along the guide shaft 34 by the sliding bushing 33 to adjust the width. The thickness adjustment plate 32 can be used to stretch the thickness of the dispensing port 14. The flexible adhesive plate 36 can ensure that the dispensing port 14 will not be pulled or damaged when the thickness adjustment plate 32 is raised.

[0029] See Figure 4 The glue application box 1 includes a glue injection tube 12, a glue storage tank 13, and a glue outlet 14. The glue storage tank 13 is located below the rear side of the substrate 4, and the glue outlet 14 is connected to the glue storage tank 13 and located below the front side of the substrate 4. The glue injection tube 12, located above the substrate 4, passes through the substrate 4 and connects to the top of the glue storage tank 13. In the above design, the glue injection tube 12 is connected to an external glue delivery pipe so that the glue is temporarily stored in the glue storage tank 13 and then applied to the application area through the glue outlet 14. The flexible glue plate 36 in this application is made of a flexible material, so the glue outlet 14 has a certain degree of extensibility, facilitating width and thickness adjustment.

[0030] See Figure 5The length measuring component 8 includes a fixed plate 81, a photoelectric encoder 82, and a length measuring wheel 83. An extension plate 42 is provided at the rear end of the base plate 4, and a second connecting seat 84 is provided below the extension plate 42. A rotating shaft 85 is provided in the second connecting seat 84. One end of the fixed plate 81 is sleeved on the rotating shaft 85, and the other end of the fixed plate 81 is provided with the length measuring wheel 83. The photoelectric encoder 82 is fixedly connected to the side of the fixed plate 81 opposite to the length measuring wheel 83. In the above design, the length measuring wheel 83 can contact the track on which the glue application box 1 is installed. The photoelectric encoder 82 and the length measuring wheel 83 are connected by counting the number of rotations of the length measuring wheel 83 to calculate the moving distance of the glue application box 1.

[0031] A caster seat 311 is provided on the outer side of the width adjustment plate 31, and the caster 11 is movably disposed in the caster seat 311. The caster 11 in the above design can facilitate the movement of the entire device along the guide rail.

[0032] The visual inspection component 9 includes a third connector 91 and a camera unit 92. The third connector 91 is fixed to the bottom of the substrate 4 and located between the length measuring component 8 and the adjustment component 3. The camera unit 92 is installed below the third connector 91. The camera unit 92 in the above design is used to capture the glue application process at the glue outlet 14.

[0033] See Figure 6 The second connecting seat 84 has a shaft hole 841 for fitting the rotating shaft 85, and the shaft hole 841 and the lower end of the second connecting seat 84 have an opening 842; an adjusting bolt 843 passes through the side end of the second connecting seat 84. The adjusting bolt 843 in the above design can adjust the tightness of the opening 842, thereby adjusting the direction of the rotating shaft 85 and controlling the direction of the fixing plate 81, so that the length measuring wheel 83 is always in contact with the track.

[0034] See Figure 7 The main control component 5 is connected to the width cylinder 21, the thickness cylinder 22, the battery box 6, the length measuring component 8, and the vision detection component 9. In the above design, the main control component 5 determines whether the glue nozzle 14 is aligned with the outer boundary line of the glue application area based on the glue application process captured by the shooting unit, and then sends a control signal to dynamically adjust the width and thickness of the glue nozzle 14 so that the shape of the applied adhesive accurately matches the actual contour of the blade bonding surface.

[0035] The battery box 6 in this invention provides power to all components.

[0036] In the specific working process, when the equipment starts working, the vision imaging component monitors the glue outlet 14 and feeds the image information back to the main control component 5 in real time. By controlling the width electric cylinder 21 of the drive component 2, the width adjustment plate 31 is adjusted asymmetrically and flexibly so that the inner working surface of the glue outlet 14 dynamically fits the outer boundary line of the glue application area in real time throughout the glue application process, ensuring that the shape of the applied adhesive accurately matches the actual contour of the blade bonding surface.

[0037] Simultaneously, the length measuring component 8 starts distance detection from the initial position of adhesive application and transmits the distance information to the main control component 5. If the adhesive application equipment reaches the point where the adhesive thickness changes, the main control component 5, upon receiving the distance information from the length measuring component 8, controls the thickness electric cylinder 22 to drive the thickness adjustment plate 32 to move to the appropriate position. This process is repeated continuously until the adhesive application is completed.

[0038] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
