Description

Technical Field

[0001] The present application belongs to the technical field of wind power generation, and in particular relates to a positioning detection device and a blade manufacturing system. Background Art

[0002] Wind turbines can capture natural wind energy and convert it into electrical energy output, and belong to the clean energy field that the country strongly supports. Wind turbine blades are the key components and the most expensive components of wind turbines. Their performance directly affects the wind energy utilization efficiency of the wind turbine and the load on the unit, and largely determines the overall performance of the unit. At the same time, it plays a key role in the safe operation of the entire wind turbine.

[0003] Wind turbine blades are composed of multiple parts such as upper and lower shells, main beams, and webs. Some of these parts can be bonded together with structural adhesives after vacuum infusion molding. At this time, the pass rate of the gap between the adhesive layers of the structural adhesive directly affects the molding quality of the blades, and the positioning accuracy of the blades directly affects the pass rate of the gap between the adhesive layers. Therefore, how to improve the positioning accuracy of the blades is crucial to improving the molding quality of the blades.

[0004] During the positioning process of the blade, a special positioning detection device can be used to verify the positioning accuracy of the blade. For example, a certain part of the blade mold can be used as a reference, and the relative position relationship between the positioning mechanism in the positioning detection device and the aforementioned reference position can be compared to determine whether the positioning of the blade is accurate. However, in the current positioning detection device, the relative position relationship between the positioning mechanism and the reference position is usually determined manually, and because the blade is set in the blade mold, the blade's cloth layer usually covers the aforementioned reference position, which makes it difficult to accurately observe the relative position relationship between the aforementioned reference position and the positioning mechanism, thereby affecting the reliability of the blade positioning accuracy verification.

DETAILED DESCRIPTION

[0028] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present application and are not configured to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0029] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0030] During the production and manufacturing process of blades, their various components can be bonded together by structural adhesive after vacuum infusion molding. At this time, the qualified rate of the glue layer gap of the structural adhesive directly affects the molding quality of the blade, and the positioning and assembly accuracy of each component directly affects the qualified rate of the glue layer gap. Therefore, how to improve the positioning accuracy of the blade is crucial to improving the molding quality of the blade.

[0031] During the positioning process of the blade, a special positioning detection device can be used to verify the positioning accuracy of the blade. It uses a certain part of the blade mold as a reference, and judges whether the positioning of the blade is accurate by comparing the relative position relationship between the positioning mechanism in the positioning detection device and the aforementioned reference position. However, in the current positioning detection device, the relative position relationship between the positioning mechanism and the reference position is usually judged manually, and because the blade is set in the blade mold, the blade's cloth layer usually covers the aforementioned reference position, which makes it difficult to accurately observe the relative position relationship between the aforementioned reference position and the positioning mechanism, thereby affecting the reliability of the blade positioning accuracy verification.

[0032] In order to solve the above technical problems, the embodiment of the present application provides a positioning detection device and a blade manufacturing system. The positioning detection device provided in the embodiment of the present application is introduced below in conjunction with the accompanying drawings.

[0033] like Figure 1 As shown, an embodiment of the present application provides a positioning detection device 100, including a bracket 110, a clamping mechanism 120, a first positioning mechanism 130 and a second positioning mechanism 140, the bracket 110 includes a first support member 111 extending along a first direction X; the clamping mechanism 120 is arranged on one side of the first support member 111 along a second direction Y, for fixing the blade 200 and the blade mold 300; the first positioning mechanism 130 is arranged on the first support member 111, for identifying the positioning mark 310 on the blade mold 300; the second positioning mechanism 140 is arranged on the first support member 111, and is spaced apart from the first positioning mechanism 130 along the first direction X, the second positioning mechanism 140 is used to align with the reference position 320 on the blade mold 300, and the first direction X is perpendicular to the second direction Y.

[0034] The bracket 110 can be used to support and fix the clamping mechanism 120, the first positioning mechanism 130 and the second positioning mechanism 140. The bracket 110 includes a first support member 111, wherein the clamping mechanism 120 can be arranged on the first support member 111, or can also be arranged at other parts of the bracket 110, for example, the bracket 110 can also include a second support member 112 connected to the first support member 111, and the clamping mechanism 120 is connected to the second support member 112. The shape of the first support member 111 can be various, for example, the first support member 111 can be a rod-shaped structure extending along the first direction X, and can also be a plate-shaped structure extending along the first direction X.

[0035] The clamping mechanism 120 is arranged on one side of the first support member 111 along the second direction Y, and can fix the blade 200 and the blade mold 300 on one side of the first support member 111 along the second direction Y, so that the first positioning mechanism 130 and the second positioning mechanism 140 located on the first support member 111 can position the blade 200 and the blade mold 300. The clamping mechanism 120 can be directly connected to the blade 200 and the blade mold 300 to fix the blade 200 and the blade mold 300, or the clamping mechanism 120 can be connected to the blade mold 300 to indirectly fix the blade 200 with the help of the blade mold 300. The structure of the clamping mechanism 120 can be various. Exemplarily, the clamping mechanism 120 can be composed of two limit members arranged opposite to each other along the second direction Y, and the two limit members can move along the second direction Y to clamp the blade 200 and the blade mold 300, or separate from the blade 200 and the blade mold 300. Alternatively, the clamping mechanism 120 may also be other structures such as a clamping claw, which is not limited in this embodiment.

[0036] The first positioning mechanism 130 and the second positioning mechanism 140 are both arranged on the first support member 111, and are spaced apart on the first support member 111 along the first direction X. During the installation of the blade 200, the second positioning mechanism 140 can be first aligned with the reference position 320 on the blade mold 300, and then the positioning mark 310 on the blade mold 300 can be identified by the first positioning mechanism 130 to determine whether the blade 200 is accurately positioned.

[0037] It should be noted that the alignment of the second positioning mechanism 140 and the reference position 320 on the blade mold 300 means that the two are aligned in the first direction X and the third direction Z, that is, in a plane perpendicular to the second direction Y, the second positioning mechanism 140 overlaps with the projection of the reference position 320 along the first direction X. In the embodiment of the present application, the first direction X may be one of the horizontal directions in the horizontal plane, the second direction Y may be a vertical direction, and the third direction Z may be another horizontal direction perpendicular to the first direction X in the horizontal plane.

[0038] On the blade mold 300, the positions of the positioning mark 310 and the reference position 320 can be various, and their actual positions can be flexibly set in actual applications, and this embodiment does not limit this. For example, the inner edge 330 of the blade mold 300 can be used as the reference position 320. For example, in the third direction Z, the positioning mark 310 can be approximately located at the center axis of the blade mold 300, and at the same time, in the first direction X, the positioning mark 310 can be located at the center position between the leading edge meter mark line and the trailing edge meter mark line of the blade mold 300.

[0039] It is understandable that there are multiple ways for the first positioning mechanism 130 to identify the corresponding positioning mark 310. For example, the first positioning mechanism 130 can identify the positioning mark 310 with the help of a laser. The first positioning mechanism 130 can emit a laser toward the blade mold 300 along the second direction Y. If the laser can coincide with the positioning mark 310, the first positioning mechanism 130 can identify the positioning mark 310, and the positioning accuracy of the blade 200 is high and the positioning deviation is small. If the laser is misaligned with the positioning mark 310, the first positioning mechanism 130 cannot identify the positioning mark 310, and the positioning deviation of the blade 200 is large. Alternatively, the first positioning mechanism 130 can also identify the positioning mark 310 with the help of X-rays, etc., and even the first positioning mechanism 130 can also be a CCD camera or other device that can identify the positioning mark 310, which is not limited in this embodiment.

[0040] There are many ways to align the second positioning mechanism 140 with the reference position 320 on the blade mold 300. For example, the second positioning mechanism 140 can be aligned with the reference position 320 on the blade mold 300 by means of a beam of light such as laser or X-ray that can penetrate the fabric layer of the blade 200. Alternatively, the second positioning mechanism 140 can be aligned with the reference position 320 on the blade mold 300 by means of technology such as electromagnetic wave detection.

[0041] In the positioning detection device 100 provided in the embodiment of the present application, the bracket 110 includes a first support member 111 extending along the first direction X, and the clamping mechanism 120 can fix the blade 200 and the blade mold 300 on one side of the first support member 111 along the second direction Y. The first positioning mechanism 130 and the second positioning mechanism 140 are arranged on the first support member 111 at intervals along the first direction X. During the installation of the blade 200, the second positioning mechanism 140 is first aligned with the reference position 320 on the blade mold 300, and then the positioning mark 310 at the preset position of the blade 200 is identified by the second positioning mechanism 140, so as to determine whether the blade 200 is accurately positioned, which helps to improve the reliability of the positioning accuracy verification of the blade 200 and improve the molding quality of the blade 200.

[0042] It can be known that when the blade 200 is accurately positioned, the distance between the positioning mark 310 of the blade mold 300 and the reference position 320 is approximately equal to the distance between the first positioning mechanism 130 and the second positioning mechanism 140, while the distance between the positioning mark 310 and the reference position 320 on the blade mold 300 corresponding to different blades 200 may be different. At this time, the distance between the first positioning mechanism 130 and the second positioning mechanism 140 can be adjusted so that the positioning detection device 100 provided in this embodiment can be adapted to different blades 200.

[0043] See also Figure 2In some embodiments, the positioning detection device 100 also includes a distance measuring mechanism 150, which is arranged on the first support member 111 and is used to measure the distance from the inner edge 330 of the blade mold 300 to the edge of the main beam 210 or the web 220 of the blade 200 along the first direction X.

[0044] There are many ways for the distance measuring mechanism 150 to measure the distance. For example, the distance measuring mechanism 150 can measure the distance by means of laser or ultrasonic wave. Alternatively, the distance measuring mechanism 150 can also include a high-precision camera such as a CCD camera to calculate the distance from the inner edge 330 of the blade mold 300 to the edge of the main beam 210 or the web 220 of the blade 200 along the first direction X by means of image acquisition. Alternatively, the distance measuring mechanism 150 can also measure the distance from the inner edge 330 to the edge of the main beam 210 or the web 220 of the blade 200 along the first direction X by means of a level ruler.

[0045] The distance measuring mechanism 150 can be directly arranged on the first support member 111, or connected to the first support member 111 by means of other structures. When the second positioning mechanism 140 is aligned with the reference position 320 on the blade mold 300, if the first positioning mechanism 130 can identify the positioning mark 310 at the preset position of the blade 200, the positioning accuracy of the blade 200 is high and the positioning deviation is small. At this time, the distance from the inner edge 330 of the blade mold 300 to the edge of the main beam 210 or the web 220 of the blade 200 along the first direction X is measured by the distance measuring mechanism 150, and relatively accurate positioning data of the main beam 210 or the web 220 can be obtained.

[0046] It should be noted that the inner edge 330 of the blade mold 300 may be a dividing line between the flange of the blade mold 300 and the main part of the blade mold 300 for supporting the blade 200. When the blade 200 is relatively accurately mounted on the blade mold 300, the distance from the inner edge 330 of the blade mold 300 to the edge of the main beam 210 of the blade 200 and the distance to the web 220 of the blade 200 are usually fixed ideal values. Therefore, the present application measures the distance from the inner edge 330 to the edge of the main beam 210 of the blade 200 and the distance to the web 220 of the blade 200 through the distance measuring mechanism 150. By comparing the aforementioned distances with the ideal values ​​calculated in advance, the positioning accuracy of the blade 200 can be further verified.

[0047] It should be noted that, in the positioning detection device 100 provided in the embodiment of the present application, a spirit level can be fixed on the positioning tooling of the blade 200, and a ruler can be vertically set at the position of the inner edge 330 of the blade mold 300. The ruler can overlap with the zero line of the spirit level to measure the distance from the inner edge 330 along the first direction X to the edge of the main beam 210 or the web 220 of the blade 200 with the help of the spirit level.

[0048] See also Figure 2 and Figure 3 In some embodiments, the reference position 320 of the blade mold 300 is the inner edge 330 of the blade mold 300, and the distance measuring mechanism 150 includes a distance meter 151, which is arranged on the first support member 111, and the transmitting end of the distance meter 151 is aligned with the second positioning mechanism 140 in the first direction X. The distance meter 151 is used to measure the distance from the reference position 320 along the first direction X to the edge of the main beam 210 or the web 220.

[0049] Specifically, there are many types of rangefinders 151, for example, the rangefinder 151 may be a laser rangefinder, an ultrasonic rangefinder, an infrared rangefinder, etc. For ease of description, the embodiment of the present application takes the rangefinder 151 as a laser rangefinder as an example to explain the corresponding solution of the embodiment.

[0050] The rangefinder 151 is disposed on the first support member 111. The transmitting end of the rangefinder 151 can face the web 220 in the first direction X. The transmitting end can emit a laser to the web 220. The optical path of the laser is parallel to the first direction X. When the laser propagates to the web 220, it can be reflected under the action of the web 220. The reflected laser is received by the rangefinder 151 again, and then the distance from the transmitting end of the rangefinder 151 to the web 220 along the first direction X is calculated. On this basis, the transmitting end of the rangefinder 151 is aligned with the second positioning mechanism 140 in the first direction X. When the second positioning mechanism 140 is aligned with the reference position 320 (i.e., the inner edge 330) of the blade mold 300, the transmitting end of the rangefinder 151 is aligned with the reference position 320. Therefore, the distance from the transmitting end of the rangefinder 151 to the web 220 along the first direction X is also the distance from the inner edge 330 of the blade mold 300 to the web 220 along the first direction X.

[0051] Similarly, the distance from the inner edge 330 of the blade mold 300 to the edge of the main beam 210 along the first direction X can be measured. It can be understood that when the rangefinder 151 is arranged on the first support member 111, the transmitting end of the rangefinder 151 can have a height difference with the edge of the main beam 210 in the second direction Y, that is, the height of the transmitting end in the second direction Y is different from the height of the edge of the main beam 210 in the second direction Y. Therefore, the laser emitted by the transmitting end of the rangefinder 151 along the first direction X is difficult to be reflected by the edge of the main beam 210. At this time, a reflection plate 154 extending along the second direction Y can be arranged at the edge of the main beam 210 to reflect the laser through the reflection plate 154, or the height position of the rangefinder 151 in the second direction Y can be adjusted so that the transmitting end of the rangefinder 151 and the edge of the main beam 210 in the second direction Y are at the same height.

[0052] It should be noted that the transmitting end of the rangefinder 151 is aligned with the second positioning mechanism 140 in the first direction X, which means that the transmitting end of the rangefinder 151 and the second positioning mechanism 140 are at the same position in the first direction X. At this time, the transmitting end of the rangefinder 151 can be located on one side of the second positioning mechanism 140 along the second direction Y, or on one side of the second positioning mechanism 140 along the third direction Z.

[0053] In these embodiments, the transmitting end of the rangefinder 151 is aligned with the second positioning mechanism 140 in the first direction X, and the reference position 320 of the blade mold 300 is the inner edge 330 of the blade mold 300. Therefore, it is only necessary to align the second positioning mechanism 140 with the reference position 320 during the process of positioning and checking the blade 200 by the first positioning mechanism 130 and the second positioning mechanism 140. The distance from the inner edge 330 to the edge of the main beam 210 or the web 220 along the first direction X can be measured by the rangefinder 151, and the corresponding main beam 210 positioning data or the web 220 positioning data can be obtained, which can reduce the difficulty of distance measurement and improve operating efficiency.

[0054] See also Figures 2 to 4 In some embodiments, the ranging mechanism 150 further includes a displacement member 152, a rotating shaft 153 and a reflecting plate 154. The displacement member 152 is disposed on the first support member 111 and is movable relative to the first support member 111 along the first direction X. The reflecting plate 154 is rotatably connected to the displacement member 152 through the rotating shaft 153. The reflecting plate 154 includes a first state and a second state. In a plane perpendicular to the first direction X, the reflecting plate 154 in the first state is misaligned with the projection of the transmitting end of the rangefinder 151 along the first direction X, and the reflecting plate 154 in the second state overlaps with the projection of the transmitting end of the rangefinder 151 along the first direction X.

[0055] The displacement member 152 is a component used to support the rotating shaft 153 and the reflecting plate 154, and drive the rotating shaft 153 and the reflecting plate 154 to move relative to the first supporting member 111 along the first direction X. The displacement member 152 is disposed on the first supporting member 111, and is disposed to move relative to the first supporting member 111 along the first direction X. When the distance from the inner edge 330 of the blade mold 300 to the edge of the main beam 210 along the first direction X is measured by the distance meter 151, the displacement member 152 can drive the reflecting plate 154 to move toward the edge of the main beam 210 along the first direction X, so that the side surface of the reflecting plate 154 close to the distance meter 151 along the first direction X is aligned with the edge of the main beam 210 along the first direction X, that is, in a plane perpendicular to the second direction Y, the side surface of the reflecting plate 154 close to the distance meter 151 along the first direction X overlaps with the projection of the edge of the main beam 210 along the second direction Y, so that the reflecting plate 154 can reflect the laser emitted by the distance meter 151. Of course, if it is necessary to measure the distance from the inner edge 330 of the blade mold 300 to other parts of the blade 200 along the first direction X through the rangefinder 151, the reflective plate 154 can also be driven by the displacement member 152 to move along the first direction X toward other parts of the blade 200, so that the side surface of the reflective plate 154 close to the rangefinder 151 along the first direction X is aligned with other parts of the blade 200 along the first direction X.

[0056] There are many ways to connect the displacement member 152 to the first support member 111. For example, the displacement member 152 can be connected to the first support member 111 by cooperating with the slide groove 1111 and the slider, or the displacement member 152 can also be connected to the first support member 111 through a cylinder, a screw rod and other mechanisms. This embodiment does not limit this.

[0057] The reflective plate 154 is used to reflect the laser emitted by the rangefinder 151. The reflective plate 154 can be used to reflect the laser when the distance from the inner edge 330 of the blade mold 300 to the edge of the main beam 210 along the first direction X is measured by the rangefinder 151, and can also be used to reflect the laser when the distance from the inner edge 330 to other parts of the blade 200 along the first direction X is measured by the rangefinder 151.

[0058] The reflective plate 154 is rotatably disposed on the displacement member 152 via the rotating shaft 153, and can be rotated relative to the displacement member 152 via the rotating shaft 153 to switch between a first state and a second state. Specifically, the first state can be a non-use state of the reflective plate 154, in which the rangefinder 151 can measure the distance from the inner edge 330 of the blade mold 300 to the web 220 along the first direction X, or the rangefinder 151 can be turned off and does not measure the distance. In the first state, in a plane perpendicular to the first direction X, the reflective plate 154 and the projection of the transmitting end of the rangefinder 151 along the first direction X are misaligned. Therefore, when the distance from the inner edge 330 of the blade mold 300 to the web 220 along the first direction X is measured by the rangefinder 151, the laser emitted by the rangefinder 151 can be directly transmitted to the web 220 without being reflected by the reflective plate 154, which can improve the accuracy of the positioning data measurement of the web 220.

[0059] The second state may be a use state of the reflector 154. In the second state, in a plane perpendicular to the first direction X, the reflector 154 overlaps with the projection of the emitting end of the rangefinder 151 along the first direction X, that is, the emitting end of the rangefinder 151 and at least part of the reflector 154 are arranged opposite to each other along the first direction X. At this time, the reflector 154 can reflect the laser emitted by the emitting end of the rangefinder 151, and the rangefinder 151 can measure the distance between the inner edge 330 of the blade mold 300 and the reflector 154 along the first direction X. At this time, if the side surface of the reflecting plate 154 close to the rangefinder 151 along the first direction X is aligned with the edge of the main beam 210 along the first direction X, then the distance from the inner edge 330 of the blade mold 300 to the reflecting plate 154 along the first direction X measured by the rangefinder 151 is the distance from the inner edge 330 to the edge of the main beam 210 along the first direction X; if the side surface of the reflecting plate 154 close to the rangefinder 151 along the first direction X is aligned with other parts of the blade 200 along the first direction X, then the distance from the inner edge 330330 of the blade mold 300 to the reflecting plate 154 along the first direction X measured by the rangefinder 151 is the distance from the inner edge 330 to other parts of the blade 200 along the first direction X, thereby improving the flexibility and application range of the distance measuring mechanism 150.

[0060] Please continue reading Figure 4 In some embodiments, the ranging mechanism 150 further includes a transmitter 155, which is disposed on the displacement member 152, and a transmitting end of the transmitter 155 is aligned with the reflective plate 154 in the first direction X, and the transmitting end of the transmitter 155 is used to emit a line beam extending at least along the second direction Y.

[0061] The emitter 155 may be a laser emitter, or may be other emitters 155 such as a ray emitter and an infrared emitter. The emitter 155 is disposed on the displacement member 152, and can move synchronously when the displacement member 152 drives the reflector 154 to move along the first direction X. The emitting end of the emitter 155 is aligned with the reflector 154 in the first direction X, which may refer to the emitting end of the emitter 155 being aligned with the surface of the reflector 154 close to the rangefinder 151 along the first direction X. At this time, the emitting end of the emitter 155 and the surface of the reflector 154 close to the rangefinder 151 along the first direction X are at the same position in the first direction X. The emitting end of the emitter 155 may be disposed on one side of the reflector 154 along the third direction Z, or on one side of the reflector 154 along the second direction Y.

[0062] When the displacement member 152 drives the reflective plate 154 to move along the first direction X, a line beam extending along the second direction Y is emitted by the transmitter 155. When the line beam passes through the edge of the main beam 210 or other positions of the blade 200, it indicates that the surface of the reflective plate 154 close to the rangefinder 151 along the first direction X is aligned with the edge of the main beam 210 or other positions of the blade 200 along the first direction X, thereby improving the positioning accuracy of the reflective plate 154 and improving the accuracy of the positioning data measured by the rangefinder 151.

[0063] It should be noted that the transmitting end of the transmitter 155 is used to emit a line beam extending at least along the second direction Y, which means that the transmitting end of the transmitter 155 can only emit a line beam extending along the second direction Y, and can also emit a line beam extending along other directions. For example, the multiple line beams emitted by the transmitting end of the transmitter 155 can be distributed in a scattered manner, and a part of the multiple line beams distributed in a scattered manner extend along the second direction Y.

[0064] Please continue reading Figure 2 and Figure 3 In some embodiments, the displacement member 152 includes a displacement body 1521 and a slider disposed on the displacement body 1521. The reflection plate 154 is connected to the displacement body 1521 through a rotating shaft 153. A slide groove 1111 extending along the first direction X is disposed on the first support member 111, and the slider is clamped in the slide groove 1111.

[0065] In these embodiments, a slide groove 1111 is provided on the first support member 111, and the slide groove 1111 extends along the first direction X. The slider on the displacement body 1521 is clamped in the slide groove 1111, so that the displacement body 1521 can drive the rotating shaft 153 and the reflective plate 154 thereon to move in the slide groove 1111 along the first direction X. The structure is simple and the operation is convenient.

[0066] Optionally, there can be two slide grooves 1111, which are arranged in parallel and at intervals on the first support member 111. There can be multiple sliders on the displacement body 1521, and the multiple sliders are respectively clamped in the two slide grooves 1111, which can improve the stability of the displacement body 1521 during movement.

[0067] In some embodiments, at least one of the first positioning mechanism 130 and the second positioning mechanism 140 includes a laser transmitter, which is beneficial for improving positioning accuracy while reducing costs.

[0068] In some embodiments, the first positioning mechanism 130 includes a cross laser emitter.

[0069] The laser beam emitted by the cross laser emitter includes two mutually perpendicular laser lines, and a cross light spot is formed at the intersection of the two laser lines. Correspondingly, the positioning mark 310 located on the blade mold 300 can be a cross shape.

[0070] When positioning the blade 200 by means of the first positioning mechanism 130 and the second positioning mechanism 140, the second positioning mechanism 140 is first aligned with the reference position 320 on the blade mold 300, and then a cross laser line is emitted toward the blade mold 300 along the second direction Y by the second positioning mechanism 140. By determining whether the laser line emitted by the first positioning mechanism 130 coincides with the cross-shaped positioning mark 310, it is possible to determine whether the blade 200 is accurately positioned, thereby facilitating high-precision positioning of the blade 200.

[0071] Please continue reading Figure 1 In some embodiments, the positioning detection device 100 also includes a level 160, which is disposed on the first support member 111. The level 160 is used to verify the horizontality of the first support member 111 so that the first support member 111 can be kept in a horizontal state as much as possible, thereby facilitating the verification of the positioning accuracy of the blade 200 and improving the reliability of the verification.

[0072] See also Figure 5 In some embodiments, the clamping mechanism 120 includes a first limit member 121 and a second limit member 122, the first limit member 121 and the second limit member 122 are arranged along the second direction Y, and at least one of the first limit member 121 and the second limit member 122 is movably arranged in the second direction Y.

[0073] The first stopper 121 and the second stopper 122 are components of the clamping mechanism 120 for clamping the blade 200 or the blade mold 300 along the second direction Y to fix the blade mold 300 and the corresponding blade 200. Specifically, the first stopper 121 and the second stopper 122 are arranged along the second direction Y, and at least one of the two is movably arranged in the second direction Y. Therefore, when it is necessary to fix the blade 200 and the blade mold 300, the blade 200 or the blade mold 300 is arranged between the first stopper 121 and the second stopper 122, so that at least one of the first stopper 121 and the second stopper 122 moves in a direction close to each other along the second direction Y, and the blade 200 and the blade mold 300 can be clamped along the second direction Y by means of the first stopper 121 and the second stopper 122, which has a simple structure and high stability.

[0074] The first stopper 121 and the second stopper 122 may be formed in various ways, for example, the first stopper 121 may be a plate-shaped structure, and the second stopper 122 may be a rod-shaped structure. At least one of the first stopper 121 and the second stopper 122 may be movably arranged along the second direction Y, the first stopper 121 may be movably arranged along the second direction Y, and the second stopper 122 may be fixed, or the second stopper 122 may be movably arranged along the second direction Y, and the first stopper 121 may be fixed, or both the first stopper 121 and the second stopper 122 may be movably arranged along the second direction Y. There are various ways for at least one of the first stopper 121 and the second stopper 122 to move along the second direction Y, for example, at least one of the first stopper 121 and the second stopper 122 may include a screw, which is threadedly connected to the bracket 110 through the screw to achieve a movable arrangement in the second direction Y. Alternatively, at least one of the first limiting member 121 and the second limiting member 122 may also be movable along the second direction Y by using an automated driving device such as a cylinder or a hydraulic cylinder.

[0075] Optionally, the first limit member 121 and the second limit member 122 can clamp the blade mold 300 along the second direction Y, specifically, can clamp the flange of the blade mold 300, so as to fix the blade 200 with the help of the blade mold 300, thereby reducing the risk of damage to the blade 200 and improving the molding quality of the blade 200.

[0076] Please continue reading Figure 5 In some embodiments, the bracket 110 also includes a second support member 112, the second support member 112 includes a guide plate 1121, the guide plate 1121 and the second limiting member 122 are both located on the side of the first limiting member 121 away from the first support member 111 along the second direction Y, the second limiting member 122 passes through the guide plate 1121 along the second direction Y and is threadedly connected to the guide plate 1121.

[0077] The second support member 112 is a component used to support the clamping mechanism 120, and then fix the blade 200 and the blade mold 300 through the clamping mechanism 120. The second support member 112 may include a support body connected to the first support member 111 and a guide plate 1121 connected to the support body, the first stopper 121 may be connected to the support body, the guide plate 1121 and the second stopper 122 are both located on the side of the first stopper 121 away from the first support member 111 along the second direction Y, the guide plate 1121 and the first stopper 121 are arranged relatively spaced apart in the second direction Y, the guide plate 1121 may be provided with a threaded hole penetrating along the second direction Y, and the second stopper 122 may pass through the threaded hole from the side of the guide plate 1121 away from the first stopper 121 along the second direction Y, and extend in a direction close to the first stopper 121. During the process of the second limiting member 122 passing through the threaded hole, the second limiting member 122 is threadedly connected to the threaded hole of the guide plate 1121, so that the second limiting member 122 can be moved in the second direction Y by rotating the second limiting member 122 to cooperate with the first limiting member 121 to lock the blade mold 300 and the blade 200. The structure is simple and the operation is convenient.

[0078] Optionally, the second limit member 122 may include a screw and a buffer portion, the screw passing through the guide plate 1121 along the second direction Y and being threadedly connected to the guide plate 1121, the buffer portion may be arranged on the side of the screw along the second direction Y close to the first limit member 121, the buffer portion is used to be located between the blade mold 300 and the screw when clamping the blade mold 300, so as to buffer the stress of the screw on the blade mold 300 and reduce the risk of damage to the blade mold 300.

[0079] Please continue reading Figure 5 In some embodiments, the clamping mechanism 120 also includes a third limit member 123, which is arranged at intervals with the first limit member 121 along the first direction X, one end of the third limit member 123 is connected to the first support member 111, and the other end is used to abut against the blade 200 or the blade mold 300.

[0080] The third stopper 123 may have a variety of shapes, for example, the third stopper 123 may be a rod-shaped structure or a block-shaped structure. The third stopper 123 is disposed on one side of the first stopper 121 along the first direction X, and is spaced apart from the first stopper 121. One end of the third stopper 123 is connected to the first support member 111, and the other end may be used to abut against the blade 200 or the blade mold 300. That is, the third stopper 123 can further support the blade 200 or the blade mold 300 on one side of the first stopper 121, thereby improving the stability of the blade mold 300 and the blade 200.
