Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade manufacturing and processing technology, and in particular to an automatic sandblasting and wire wrapping workstation for wind turbine blade bolt sleeves. Background Technology

[0002] A wind turbine is a power generation device that converts wind energy into mechanical energy and then into electrical energy through blades. The blades are a key component of a wind turbine, and high-strength bolt sleeves are typically pre-embedded on the end face at the blade root, connecting it to the hub via bolts. To enhance the strength of the bolt sleeves embedded in the blade, fiberglass filaments are wound around their surface. Furthermore, before winding the filaments, the bolt sleeves need to be sandblasted to effectively remove rust, dirt, and oxide layers from their surface, while also increasing surface roughness to improve the adhesion of the subsequent filament winding process. Therefore, this places higher demands on the large-scale production and processing of these bolt sleeves.

[0003] In existing technologies, the production and processing of bolt sleeves are all done manually. Workers need to frequently move bolt sleeves between loading / unloading stations, sandblasting stations, and wire winding stations. This not only consumes a lot of time and manpower, but also easily leads to damage to the bolt sleeves or inaccurate placement due to fatigue or negligence, affecting the normal progress of subsequent processing steps. Moreover, the production cycle is long, making it impossible to achieve efficient integrated production, which affects the improvement of production efficiency and product quality.

[0033] This utility model provides an automatic sandblasting and wire wrapping workstation for wind turbine blade bolt sleeves, such as... Figures 1-6As shown, the workstation includes a loading pallet 1, a unloading pallet 2, a sandblasting device 3, a first wire winding device 4, a second wire winding device 5, and a robotic arm 6. The sandblasting device 3, the first wire winding device 4, the second wire winding device 5, and the robotic arm 6 are all connected to an electrical control device 7. The workstation also includes a fence 8, which encloses the workstation, clearly defining the work area and the activity area. This concentrates all equipment within the workstation into a relatively enclosed work area, facilitating centralized monitoring and management of the entire production process by management personnel. The fence 8 isolates the work area from the operator's activity area, preventing operators from accidentally entering dangerous work areas, avoiding safety accidents, and ensuring the personal safety of operators. A fence opening 801 is located below the front of the fence 8. The loading pallet 1 and the unloading pallet 2 are located inside the fence opening 801. A telescopic gate 802 is located at the fence opening 801 and is connected to the electrical control device 7. A pallet truck 803 is parked outside the workstation. The loading pallet 1 has a uniform array of loading positioning posts 101, and the unloading pallet 2 has a uniform array of unloading positioning posts 201. The loading positioning posts 101 and unloading positioning posts 201 are respectively matched with bolt sleeves so that the bolt sleeves can be fitted onto the loading positioning posts 101 and unloading positioning posts 201, thereby realizing the loading and unloading of bolt sleeves. Specifically, when the telescopic gate 802 is opened by the electronic control device 7 and loading is required, the pallet transport vehicle 803 will transport the loading pallet 1 containing bolt sleeves through the fence opening 801 to the loading position in the workstation, so that the robot arm 6 can pick up the bolt sleeves. After the robot arm 6 unloads the sandblasted and wire-wrapped bolt sleeves onto the unloading pallet 2, the pallet transport vehicle 803 can transport the unloading pallet 2 out of the workstation, further avoiding manual loading and unloading and improving production efficiency.

[0034] The sandblasting device 3 is equipped with a sandblasting worktable 301 and a sandblasting gun (not shown). A turntable 302 is rotatably connected to the sandblasting worktable 301, and the turntable 302 has several sandblasting processing positions 303. The turntable 302 is connected to a turntable 302 drive (not shown). When the turntable 302 drive drives the turntable 302 to rotate, it can move the bolt sleeve placed on the turntable 302 to the sandblasting gun, so that the sandblasting gun can sandblast the bolt sleeve. After the robotic arm 6 picks up the bolt sleeve from the loading tray 1, it places the bolt sleeve on the sandblasting processing position 303. When the sandblasting device 3 is started by the electronic control device 7, it controls the turntable 302 drive to rotate, which in turn rotates the bolt sleeve to the sandblasting gun to achieve sandblasting. The robotic arm 6 replaces manual picking, ensuring the safety of the workers and improving production efficiency.

[0035] In this embodiment, the workstation includes two wire winding machines, namely the first wire winding machine and the second wire winding machine. These two wire winding machines have the same structure. By using two wire winding machines, the production efficiency of wire winding for bolt sleeves is also improved. The structure and working process of the first wire winding machine are described below as an example.

[0036] The first fiber winding machine includes a frame 401. One end of the frame 401 has a support portion 402, and the other end has a moving portion 403. A gap area 404 is provided between the support portion 402 and the moving portion 403 for placing a bolt sleeve. A first positioning sleeve 405 is provided on the support portion 402, and a second positioning sleeve 406 is provided on the moving portion 403. The first positioning sleeve 405 and the second positioning sleeve 406 are coaxially arranged opposite each other, thus coaxially fixing the bolt sleeve between the first positioning sleeve 405 and the second positioning sleeve 406. A first driving member 407 is provided on the support portion 402 to drive the bolt sleeve to rotate, and a second driving member 408 is provided on the moving portion 403 to drive the moving portion 403 to move towards the support portion 402. The frame 401 also has a wire tensioning portion 409, which is used to straighten and guide the glass fiber filaments as they are wound onto the bolt sleeve. Specifically, after the bolt sleeve is placed in the interval area 404, one end of the bolt sleeve is fixed on the first positioning sleeve 405. At this time, the second driving member 408 is activated, which drives the moving part 403 to move towards the support part 402, thereby moving the second positioning sleeve 406 towards the first positioning sleeve 405, thus tightening and fixing the bolt sleeve between the first positioning sleeve 405 and the second positioning sleeve 406. Then, the first driving member 407 is activated, causing the bolt sleeve to rotate. The wire tensioning part 409 feeds the wire and evenly wraps the glass fiber wire around the entire surface of the bolt sleeve to complete the wire wrapping operation. After the wire wrapping is completed, the bolt sleeve stops rotating and waits for the operator to pick it up.

[0037] In this embodiment, the frame 401 of the first wire winding device 4 is also equipped with an automatic wire winding and feeding assembly. The automatic wire winding and feeding assembly is located on the front side of the interval area 404 to facilitate the feeding of the sandblasted bolt sleeves between the first positioning sleeve 405 and the second positioning sleeve 406. The automatic wire winding and feeding assembly includes an automatic feeding platform 410, on which a first support 411 and a second support 412 are arranged opposite to each other. The lower end of the automatic feeding platform 410 is connected to a third driving member 413, and the rear end of the automatic feeding platform 410 is connected to a fourth driving member 414. The third driving member 413 can drive the automatic feeding platform 410 to move up and down, and the fourth driving member 414 drives the automatic feeding platform 410 to move back and forth. Specifically, after the robotic arm 6 places the sandblasted bolt sleeve on the first support 411 and the second support 412, it activates the third drive unit 413 to move the automatic feeding table 410 upward to the same height as the first positioning sleeve 405 and the second positioning sleeve 406. Then, it activates the fourth drive unit 414 to move the automatic feeding table 410 between the first positioning sleeve 405 and the second positioning sleeve 406 to perform the wire winding operation on the bolt sleeve. By setting up an automatic wire winding and feeding assembly, manual intervention is reduced, ensuring the automation of bolt sleeve production and improving production efficiency.

[0038] The robotic arm 6 is located in the center of the fence 8. This layout allows the robotic arm 6 to have a relatively central operating position within the work space defined by the fence 8, enabling it to more easily reach different areas within the fence 8 and perform clamping operations on bolt sleeves at various locations. This improves the working range and flexibility, reducing operational inconvenience caused by remote locations or the need for additional mobile equipment. The robotic arm 6 is a six-axis robotic arm 601. The bottom of the six-axis robotic arm 601 is rotatably connected to the base 602, providing the robotic arm with the freedom of rotation in the horizontal plane. This allows it to rotate a wide range around the center of the base 602 and quickly change the working direction. The end of the six-axis robotic arm 601 furthest from the base 602 is rotatably connected to a mounting bracket 603. Two symmetrically arranged grippers 604 are fixedly connected to the mounting bracket 603. The grippers 604 are used to clamp bolt sleeves. The shape of the grippers 604 matches the shape of the bolt sleeve to ensure that the grippers 604 can accurately align with the bolt sleeve and clamp it stably. By setting two grippers 604, the robotic arm 6 can grab two bolt sleeves at a time, which further ensures production efficiency.

[0039] The workstation in this embodiment also includes a sampling inspection table 9. The sampling inspection table 9 is equipped with a guide rail 902, and a slider 903 is slidably connected to the guide rail 902. A sampling inspection bracket 901 is fixed to the slider 903. The sampling inspection bracket 901 is used to hold the bolt sleeves. The slider 903 is connected to a sampling inspection drive. Specifically, when the sampling inspection drive is activated, it drives the slider 903 to move along the guide rail 902, which in turn moves the sampling inspection bracket 901, and then moves the bolt sleeves, thus moving the bolt sleeves to a position away from the robotic arm 6. This allows the operator to perform sampling inspections on the bolt sleeves, achieving convenient sampling inspection, reducing manual operation, and ensuring the quality of bolt sleeve production.

[0040] A protective box 904 is installed at the end of the sampling inspection table 9 furthest from the robotic arm 6, and the protective box 904 is fixedly connected to the sampling inspection table 9. The protective box 904 is equipped with several buttons to facilitate sampling by the operator. In addition, the protective box 904 can also serve as an isolation and protection mechanism, preventing bolt sleeves or other items from accidentally falling and causing injury to the operator during the sampling inspection process, and protecting the safety of surrounding personnel.

[0041] To better illustrate the working method of this utility model, the working steps of this automatic sandblasting and wire wrapping workstation for wind turbine blade bolt sleeves are as follows:

[0042] Step 1: Open the telescopic gate 802. The staff uses the pallet truck 803 to transport the unloading pallet 2 and the loading pallet 1 containing the bolt sleeves to be processed to the workstation, and then close the telescopic gate 802.

[0043] Step 2: Start the sandblasting device 3, and use the electronic control device 7 to make the robot arm 6 pick up at least six bolt sleeves from the loading tray 1 and place them on the sandblasting processing position 303 respectively, so that the sandblasting gun can sandblast each bolt sleeve.

[0044] Step 3: The robotic arm 6 is controlled by the electronic control device 7 to pick up the two sandblasted bolt sleeves and place them on the sampling inspection table 9, waiting for the operator to conduct the sampling inspection.

[0045] Step 4: After the random inspection is qualified, the robot arm 6 is used by the electronic control device 7 to pick up the bolt sleeves that have been sandblasted on the two sandblasting devices 3. One bolt sleeve is placed on the automatic feeding table 410 of the first wire winding device 4 for wire winding operation, and the other bolt sleeve is placed on the automatic feeding table 410 of the second wire winding device 5 for wire winding operation.

[0046] Step 5: The robot arm 6 is controlled by the electronic control device 7 to pick up two unprocessed bolt sleeves from the loading tray 1 and place them on the sandblasting processing position 303 for sandblasting. Then, the two sandblasted bolt sleeves are picked up.

[0047] Step 6: The robot arm 6 uses the electronic control device 7 to place one of the two sandblasted bolt sleeves from step 5 onto the automatic feeding table 410 of the first wire winding machine, and then takes one bolt sleeve that has been wound with wire from the first wire winding machine.

[0048] Step 7: The robot arm 6 uses the electronic control device 7 to place the other of the two bolt sleeves after sandblasting in step 5 onto the automatic feeding table 410 of the second wire winding machine, and picks up one bolt sleeve that has been wire-wound on the second wire winding machine; at this time, the two grippers 604 of the robot arm 6 pick up the bolt sleeve that has been wire-wound respectively.

[0049] Step 8: The robotic arm 6 places the two wire-wrapped bolt sleeves onto the unloading tray 2 via the electronic control device 7;

[0050] Step 9: Repeat steps 5 to 8 until all bolt sleeves are sandblasted, wire-wrapped, and placed on the unloading tray 2;

[0051] Step 10: Open the telescopic gate 802. The staff uses the pallet truck 803 to transport the unloading pallet 2 containing the bolt sleeves that have been sandblasted and wrapped to the outside of the workstation, and then close the telescopic gate 802.

[0052] In this embodiment, it should be noted that the winding structure of the electronic control device 7, the six-axis robotic arm 601, the sandblasting device 3, and the winding device are all existing technologies in the field.
