[0002] When manufacturing wind turbine blades, the upper shell and the lower shell of the blade need to be bonded together in a mold. After the mold is solidified, the part of the bonding point that exceeds the blade contour (i.e., the flash) needs to be cut so that the blade can finally meet the standard contour requirements.

[0003] The prior art generally relies on an AGV trolley to guide the cutting device.

During cutting, the guide wheel on the cutting device needs to be inserted into the positioning groove at the flash edge of the blade. This type of AGV trolley-guided cutting method requires real-time monitoring of the cutting process. In the prior art, a monitoring camera is generally fixed on the cutting device to realize real-time monitoring of the cutting process. This type of monitoring is difficult to achieve all-round monitoring, and it is also impossible to adjust the monitoring range of the monitoring camera according to the actual cutting situation. Therefore, the existing monitoring process needs to be further improved. Utility Model Content

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Example 1

[0023] Wind turbine blade flash cutting device, such as Figure 1-Figure 5 As shown, it comprises a mounting frame 1, on which a vertical angle adjustment frame 2 is mounted, the vertical angle adjustment frame 2 comprises a mounting back plate 201 for mounting a cutting head, a rotating seat 202 connected between the mounting back plate 201 and the mounting frame 1, and a vertical driving mechanism 203 for driving the mounting back plate 201 to rotate around a rotating axis of the rotating seat 202, wherein the rotating axis of the rotating seat 202 is axially arranged horizontally along the blade flash cutting direction;

[0024] The rotating seat 202 includes a first rotating part installed in the middle of the mounting back plate 201 and a second rotating part installed in the lower part of the mounting frame 1. The first rotating part and the second rotating part are connected by a rotating pin arranged horizontally along the cutting direction of the blade flash. The first rotating part and the second rotating part rotate relative to each other around the rotating pin, so that the mounting back plate 201 can rotate up and down around the mounting frame 1, and then the cutting head on the mounting back plate 201 can cut into the flash vertically, and the guide wheel can be vertically inserted into the positioning groove of the flash, so as to ensure that the cutting surface is a vertical plane and the guiding precision is ensured.

[0025] The vertical driving mechanism 203 includes a driving electric cylinder 204 installed on the mounting back plate 201 and the driving shaft can extend horizontally toward the mounting frame 1. The top of the mounting frame 1 is provided with a driving head 205 and a driving head mounting seat 206. One end of the driving head 205 is installed on the driving head mounting seat 206 by a high-height screw, and the other end is provided with a positioning hole 207 for the driving shaft of the driving electric cylinder 204 to extend into and position.

[0026] In this embodiment, the drive head mounting seat 206 includes a base 208 with an L-shaped structure and a connecting seat 209 fixed on the base 208. The base 208 is fixed on the mounting frame 1. The connecting seat 209 includes two connecting plates 210 arranged opposite to each other. The end of the drive head 205 is arranged between the two connecting plates 210. The end of the drive head 205 and the two connecting plates 210 are provided with connecting holes 211 that cooperate with the same height screws. The structural form of the drive head mounting seat 206 can make it better fixed on the top of the mounting frame 1, the structure is compact, and it can play a better connection role.

[0027] Compared with conventional pneumatic cylinders, electric cylinders are used to adjust the cutting angle in the vertical direction, which can achieve more precise control locally and effectively ensure that the cutting knife can be completely perpendicular to the cut surface of the blade, making the cutting effect more stable and the cutting accuracy higher; at the same time, it ensures that the guide wheel on the cutting device can be completely vertically inserted into the flash groove of the blade, fully ensuring stable and precise guidance.

[0028] The installation of the drive head 205 is achieved by using equal height screws. While fixing and limiting the drive head 205, the equal height screws can also act as an axle pin, so that the drive head 205 can rotate relative to the axis of the equal height screws when adjustment is required, thereby facilitating the pitch adjustment of the entire vertical angle adjustment frame 2.

[0029] In this embodiment, a cutting head mounting mechanism is installed on the mounting back plate 201, and the cutting head mounting mechanism includes a cutting head mounting frame 4. A cutting head mounting frame 7 is also installed on the mounting back plate 201. A disc cutting knife 401 and a disc cutting knife 402 are respectively installed on the cutting head mounting frame 4 and the cutting head mounting frame 7. An emergency protection frame 6 is also installed on the cutting head mounting frame 7. The emergency protection frame 6 is arranged in front of the disc cutting knife 402 along the cutting direction of the disc cutting knife 401. The emergency protection frame 6 includes a vertically arranged fixing rod 601. The lower end of the fixing rod 601 is provided with a glass bead screw (not shown in the figure) that can be tightly pressed against the upper surface of the flash blade.

[0030] Since wind turbine blades are made of composite materials with high hardness, when the cutting head cuts the blade, the glass bead screw rests on the surface of the blade as the cutting knife moves forward and cuts. The steel ball at the bottom of the glass bead screw and the spring inside it have a certain buffering effect. In addition, the installation height of the glass bead screw can be adjusted by adjusting the number of screw turns, thereby realizing the adjustment of the buffer position when cutting.

[0031] In addition, in this embodiment, the lower end of the fixed rod 601 is also provided with a baffle 602 extending downward and capable of blocking the disc cutting knife 401 in the axial direction of the disc cutting knife 401. The baffle 602 is arranged parallel to the cutting surface of the disc cutting knife 401, and the baffle 602 is arranged behind the disc cutting knife 401 along the cutting direction of the disc cutting knife 402.

[0032] During the cutting process, the position of the cutting blade will be adjusted according to the requirements of the cutting angle and will move to the front of the baffle 602. During the forward movement of the cutting blade, due to the different resistances received by the cutting blade, it will swing laterally. During the swinging process, the baffle 602 can block the cutting blade and achieve limit protection under extreme conditions.

[0033] In this embodiment, the cutting head mounting frame 4 includes a cutting head mounting arm 417 and a mounting arm driving mechanism 403 for driving the cutting head mounting arm 417 to rotate. One end of the cutting head mounting arm 417 is connected to the mounting arm driving mechanism 403, and the other end is used to install the cutting head driving mechanism 404 for realizing the cutting head rotation. The rotation axis of the cutting head mounting arm 417 is arranged parallel to the cutting rotation axis of the cutting head.

Then, the rotation angle of the cutting knife around the axis can be adjusted better according to the different positions of the blades, and the cutting starting angle can be adjusted, thereby obtaining a better incision.

An output disk 412 is connected to the flange 411 through a bearing, and the flexible wheel 409 is connected to the cutting head mounting arm 417 through the output disk 412. The setting of the harmonic reducer 407 can realize the stable driving of the mounting arm 417 by the mounting arm driving motor 406, thereby ensuring the precise adjustment of the cutting angle of the cutting head.
