Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade manufacturing technology, and in particular to a gluing machine for wind turbine blade blanks. Background Technology

[0002] As the timetable for the depletion of traditional fossil energy sources such as coal, oil, and natural gas draws ever closer, the development and utilization of wind energy is receiving increasing attention and has become one of the most commercially promising projects in the energy sector. Currently, it is developing rapidly both domestically and internationally. The development of wind power generation depends on the production and manufacturing of a large number of wind turbines. Wind turbines cannot function without wind turbine blades. During the manufacturing process, a layer of gel coat is sprayed onto the surface of the wind turbine blades, thus requiring the use of corresponding blade coating equipment.

[0003] Chinese utility model patent CN220294989U discloses a wind turbine blade coating device, including an inverted L-shaped column and a traveling mechanism. The inverted L-shaped column is fixedly installed on the ground, and a connecting column is fixedly connected to the horizontal front end of the column. A flange ring is fixedly connected to the front end of the connecting column, and a blade is fixedly connected to the flange ring by bolts. The traveling mechanism is located below the blade, and robotic arms are symmetrically fixedly connected to the top of the traveling mechanism on both sides of the blade. A nozzle is rotatably connected to the front end of each robotic arm. An air compressor and a storage tank are fixedly installed on the top of the traveling mechanism. The output end of the storage tank is connected to the corresponding nozzle via a T-junction and a material guide hose, and the output end of the air compressor is connected to the corresponding nozzle via a T-junction and an air pipe. This wind turbine blade coating device... When using the adhesive spraying equipment, the blades to be sprayed with adhesive are fixed to the flange ring with bolts, achieving a suspended installation of the blades. A servo motor drives the walking mechanism to move on the guide rail. The output end of the servo motor drives the main sprocket to rotate, and the main sprocket drives the driven sprocket to rotate through the chain. The driven sprocket drives the connecting shaft to rotate, thereby moving the device through the wheels. The walking mechanism is controlled to move the same distance each time, which is the width of the spray. Between each start and stop of the servo motor, the robotic arm carries the nozzle to spray the adhesive onto the surface of the blade. The blade is sprayed with adhesive evenly from head to tail, achieving the goal of spraying the adhesive onto the blade in one pass. However, when spraying adhesive onto the surface of the blade, the machine will vibrate, causing the walking mechanism to move on the guide rail, which will affect the operation of spraying adhesive onto the surface of the blade. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a wind turbine blade blank gluing machine to solve the technical problem that when the existing wind turbine blade gluing equipment sprays glue on the blade surface, the machine vibrates, causing the walking mechanism to move on the guide rail, which affects the work of spraying glue on the blade surface.

[0005] To achieve the above technical objectives, the present invention provides a wind turbine blade blank gluing machine, including a blade installation device and a glue spraying device. The blade installation device includes an inverted L-shaped column installed on the ground. A connecting column is fixedly connected to the horizontal front end of the inverted L-shaped column. A flange ring is fixedly connected to the front end of the connecting column. The flange ring is fixedly connected to the blade by bolts. The glue spraying device includes a traveling mechanism located below the blade. Two robotic arms are symmetrically installed on the top of the traveling mechanism and on both sides of the blade. The front ends of the two robotic arms are rotatably connected to nozzles. A storage tank and an air compressor frame are also installed on the top of the traveling mechanism. The output end of the storage tank is connected to the corresponding nozzle through a tee and a material guide hose. The output end of the air compressor is connected to the corresponding nozzle through a tee and an air pipe. Two sets of wheel assemblies are installed at the bottom of the traveling mechanism. The two sets of wheel assemblies are rolled on a guide rail embedded in the ground. The glue spraying device also includes a positioning assembly, which includes a positioning rod and a driving component for driving the positioning rod to move along its central axis. The driving component is installed on the traveling mechanism. The guide rail has multiple positioning holes at equal intervals along its length that cooperate with the positioning rod.

[0006] Furthermore, the adhesive spraying device also includes a detection component for detecting the movement position of the walking mechanism, and the detection component, positioning component, and wheel assembly are electrically connected to the controller.

[0007] Furthermore, the detection component includes a contact switch mounted on the walking mechanism and multiple contact wheels that cooperate with the contact switch, which are mounted at equal intervals along the length of the guide rail.

[0008] Furthermore, the wheel assembly includes a connecting shaft with wheels mounted at both ends. The connecting shaft is rotatably mounted on the traveling mechanism via bearings. A driven sprocket is coaxially mounted on the connecting shaft, and the driven sprocket is connected to the main sprocket via a chain. The main sprocket is connected to the output shaft of the motor.

[0009] Furthermore, guide grooves are provided on both sides of the top of the guide rail and along its length, and the wheels roll inside the guide grooves.

[0010] Furthermore, a collection box for collecting glue is provided on the top of the walking mechanism and directly below the blade.

[0011] The beneficial effects of this utility model include:

[0012] 1. Before the traveling mechanism stops moving to spray the adhesive onto the blade surface, the positioning rod can be driven to move by the driving component to insert and fix the positioning rod into the corresponding positioning hole. This fixes the position of the traveling mechanism and prevents it from moving on the guide rail due to machine vibration during the spraying work on the blade surface. This avoids affecting the spraying work on the blade surface. 2. When the traveling mechanism moves to the designated position for applying the adhesive to the blade, the detection component detects the position information and sends the detected information to the controller. The controller can control the traveling mechanism to stop moving based on the detected information, and at the same time control the positioning component to fix the traveling mechanism on the guide rail, so as to accurately control the position where the traveling mechanism stops moving. This allows for precise control of the position of the spraying point and improves the effect of spraying the adhesive. Attached Figure Description

[0014] 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 the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] This utility model embodiment provides a gluing machine for wind turbine blade blanks, such as... Figure 1-2As shown, the device includes a blade mounting device 1 and a glue spraying device 2. The blade mounting device 1 includes an inverted L-shaped column 11 installed on the ground. A connecting column 12 is fixedly connected to the horizontal front end of the inverted L-shaped column 11. A flange ring 13 is fixedly connected to the front end of the connecting column 12. A blade 14 is fixedly connected to the flange ring 13 by bolts. The glue spraying device 2 includes a traveling mechanism 21 located below the blade 14. Two robotic arms 22 are symmetrically installed on the top of the traveling mechanism 21 and on both sides of the blade 14. A spray nozzle 23 is rotatably connected to the front end of the two robotic arms 22. A storage tank 24 and an air compressor are also installed on the top of the traveling mechanism 21. The output ends of the compressor 25 and the storage tank 24 are connected to the corresponding nozzles 23 via a T-junction and a material guide hose. The output end of the air compressor 25 is connected to the corresponding nozzles 23 via a T-junction and an air pipe. The walking mechanism 21 can move on top of the guide rail 26 embedded in the ground. When the walking mechanism 21 moves a certain distance, it stops moving. During the period when the walking mechanism 21 stops moving, the nozzles 23 can be driven to move by the robotic arm 22 to spray the adhesive on a certain area of ​​the blade surface. After the adhesive is sprayed on a certain area of ​​the blade surface, the walking mechanism 21 moves to the next spraying point to spray the adhesive on the entire surface of the blade.

[0016] In this embodiment, as Figure 3 As shown, the glue spraying device 2 also includes a positioning component 27. The positioning component 27 includes a positioning rod 271 and a driving member 272 for driving the positioning rod 271 to move along its central axis. The driving member 272 is one of a cylinder, a hydraulic cylinder, or an electric telescopic rod. The driving member 272 is mounted on the traveling mechanism 21. The guide rail 26 is provided with a plurality of positioning holes 261 that cooperate with the positioning rod 271 at equal intervals along its length. Before the traveling mechanism 21 stops moving to spray glue on the blade surface, the driving member 271 can drive the positioning rod 272 to move, so as to insert and fix the positioning rod 272 into the corresponding positioning hole 261. This can fix the position of the traveling mechanism 21, so as to avoid the machine from vibrating and causing the traveling mechanism 21 to move on the guide rail 26 when spraying the blade surface. Therefore, it can avoid affecting the work of spraying glue on the blade surface. At the same time, the head of the positioning rod 271 is a conical structure, which makes it easier to insert the positioning rod 271 into the positioning hole 261.

[0017] In this embodiment, as Figure 4As shown, the glue spraying device 2 also includes a detection component 28 for detecting the movement position of the walking mechanism 21. The detection component 28, the positioning component 27, and the walking mechanism 21 are electrically connected to the controller 29. When the walking mechanism 21 moves to the designated blade coating position, the detection component 28 detects the position information and sends the detected information to the controller 29. The controller 29 can control the walking mechanism 21 to stop moving according to the detected information, and at the same time control the positioning component 27 to fix the walking mechanism 21 on the guide rail 26 to accurately control the position where the walking mechanism 21 stops moving. This allows for precise control of the spraying point position and improves the effect of the glue spraying. Meanwhile, the detection component 28 includes a contact switch 281 installed on the walking mechanism 21 and multiple contact wheels 282 that cooperate with the contact switch 281 and are installed at equal intervals along the length of the guide rail 26. When the walking mechanism 21 moves to the point where the contact switch 281 contacts the contact wheel 282, the walking mechanism 21 stops moving, resulting in good positioning effect.

[0018] The traveling mechanism 21 includes a frame 211 and two sets of wheel assemblies 212 symmetrically arranged at the bottom of the frame 211. Each wheel assembly 212 includes a connecting shaft 2121, with wheels 2122 mounted at both ends. The connecting shaft 2121 is rotatably mounted at the bottom of the frame 211 via bearings. A driven sprocket 2123 is coaxially mounted on the connecting shaft 2121. The driven sprocket 2123 is connected to the main sprocket 2125 via a chain 2124. The main sprocket 2125 is connected to the electric motor. The output shaft of the motor 2126 is connected, and guide grooves 262 are provided on both sides of the top of the guide rail 26 and along its length. The wheel 2122 is rolled inside the guide groove 262. The motor 2126 can drive the main sprocket 2125 to rotate. The main sprocket 2125 can drive the slave sprocket 2123 to rotate through the chain 2124. The slave sprocket 2123 can drive the connecting shaft 2121 to rotate. The connecting shaft 2121 can drive the wheel 2122 to roll inside the guide groove 262.

[0019] In this embodiment, a collection box 210 for collecting glue is provided on the top of the walking mechanism 21 and directly below the blade 14. After the glue is sprayed on the surface of the blade, some of the glue can flow down from the blade 14 and drip into the collection box 210 for collection. This can prevent the glue from contaminating the workshop and can also recycle and reuse the glue, avoiding waste.

[0020] Specific principle: The walking mechanism 21 can move on top of the guide rail 26 embedded in the ground. After the walking mechanism 21 moves a certain distance, the contact switch 281 contacts the contact wheel 282, and the controller 29 controls the walking mechanism 21 to stop moving. At the same time, the drive component 272 drives the positioning rod 271 to insert and fix it in the corresponding positioning hole 261 to fix the walking mechanism 21 on the guide rail 26. During the period when the walking mechanism 21 stops moving, the robotic arm 22 drives the spray head 23 to move and spray the adhesive on a certain area of ​​the blade surface. After the adhesive is sprayed on a certain area of ​​the blade surface, the drive component 272 drives the positioning rod 271 to be pulled out from the positioning hole 261 to release the walking mechanism 21 from the guide rail 26. After the walking mechanism 21 is released from the guide rail 26, the walking mechanism 21 moves to the next spraying point to spray the adhesive on the entire surface of the blade.

[0021] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
