Description

Technical Field

[0001] The present application relates to the technical field of emery wire detection, and in particular to an emery wire oblique tension detection device in a photovoltaic pay-off room. Background Art

[0002] For the cutting of highly hard and brittle materials, wire cutting machines have become the mainstream product on the market due to their absolute advantages in terms of output rate, cutting efficiency, production cost, and environmental protection.

[0003] The photovoltaic pay-off chamber of the wire cutting machine uses a roller to drive the emery wire. Two winding rollers are respectively arranged in the photovoltaic pay-off chamber, and the winding rollers are driven by a driving motor to rotate, and the winding rollers wind up the emery wire. A guide wheel for guiding the emery wire is installed in the photovoltaic pay-off chamber, and a moving track corresponding to the guide wheel is arranged in the photovoltaic pay-off chamber. A moving motor for driving the guide wheel to move along the moving track is installed on the moving track. The guide wheel moves along the moving track along with the winding action of the winding roller. When the winding roller switches between winding and paying out, the angle of the emery wire on the winding roller will deviate. Excessive deviation can easily lead to overpressure during the winding process, and then it is easy to be broken during unwinding. Once it is broken, it is necessary to stop the machine for welding or melting or even replace the emery wire, which is time-consuming and labor-intensive to repair. Utility Model Content

[0004] In order to detect the deviation occurring during the unwinding process of the emery wire, the present application provides an emery wire oblique tension detection device for a photovoltaic pay-off room.

[0007] By adopting the above technical solution, the camera captures images of the end of the emery wire, and then detects whether the emery wire is offset and the amount of offset, thereby reducing the phenomenon of the emery wire being broken.

[0008] Optionally, the camera includes a first camera and a second camera arranged in parallel, and the first camera and the second camera are arranged along the extension direction of the emery line.

[0009] By adopting the above technical solution, the first camera and the second camera simultaneously capture images of the position of the emery wire, lengthen the detection length, and more accurately detect the deviation of the emery wire during the winding and unwinding process through photos.

[0010] Optionally, the detection housing is provided with fill light sources respectively mounted outside the first camera and the second camera.

[0011] By adopting the above technical solution, the first camera and the second camera are supplemented with light through the supplementary light source, thereby improving the effect of image acquisition.

[0012] Optionally, a screw cap corresponding to each glass protection sheet is movably connected to the outer side of the detection housing.

[0013] By adopting the above technical solution, when the first camera and the second camera are not capturing images, the rotary cover blocks the first camera and the second camera in the glass protective sheet to protect the glass protective sheet and prevent the refraction of water droplets of coolant from affecting the detection accuracy. When the winding roller switches between winding and paying out, the rotary cover is rotated by the rotating rod, and the first camera and the second camera capture images.

[0014] Optionally, the two rotary covers are fixedly connected, and a rotating rod is provided at the connection, and the rotating rod is rotatably connected to the detection housing.

[0016] Optionally, the first camera and the second camera are both electrically connected to a control module, and the control module is electrically connected to a driving motor and a moving motor, respectively.

[0017] By adopting the above technical solution, when the direction of the driving motor changes, the winding and unwinding operations of the winding roller change and the change signal is sent to the control module. The control module controls the first camera and the second camera to acquire images. The images acquired by the first camera and the second camera are sent to the control module. The control module analyzes and processes the transmitted images, calculates the offset of the emery wire and controls the moving motor, changes the moving speed of the guide wheel, and ensures that the winding roller performs normal winding and unwinding operations.

[0018] Optionally, a drive motor is disposed in the detection housing, an output shaft of the drive motor is fixedly connected to the rotating rod, and the drive motor is electrically connected to the control module.

[0019] By adopting the above technical solution, when the control module receives the signal of the change of the winding and unwinding operation of the winding roller, it controls the rotating rod to rotate by controlling the driving motor, opens the rotary cover, and performs image acquisition. After the image acquisition is completed, it controls the rotating rod to rotate by controlling the driving motor to close the rotary cover.

[0020] Optionally, the fill light source is electrically connected to the control module.

[0021] By adopting the above technical solution, when the control module receives the signal of the change of the winding and unwinding operation of the winding roller, the fill light source is turned on for fill light, and after the image acquisition is completed, the fill light source is turned off, which is conducive to saving energy.

[0032] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0033] Embodiment 1:

[0034] Reference Figure 1A photovoltaic pay-off room diamond abrasive wire oblique tension detection device includes a detection shell 2, the outer surface of the detection shell 2 is fixedly connected to a connecting frame 1, and the connecting frame 1 is provided with a connecting hole 11. The connecting frame 1 and the connecting hole 11 can be used to install it on a guide wheel, so that the detection shell 2 moves along with the guide wheel.

[0035] Reference Figure 1 and Figure 2 A camera facing the emery wire is provided in the detection housing 2. When the emery wire changes direction, the camera takes a picture of the emery wire. The camera may be composed of one or more cameras. In this embodiment, the camera includes a first camera 3 and a second camera 4. The first camera 3 and the second camera 4 are arranged along the extension direction of the emery wire. The first camera 3 and the second camera 4 take pictures at the same time. The offset of the emery wire during the winding and unwinding process is detected through the pictures. The speed of the guide wheel moving along the moving track is controlled according to the offset, so as to reduce the angle of the emery wire on the winding roller and reduce the possibility of the emery wire breaking.

[0036] Reference Figure 3 and Figure 4 The first camera 3 and the second camera 4 are provided with a fill light source 5 located in the detection housing 2. The fill light source 5 is a commonly used fill light. The light conditions in the cutting room are poor. The fill light source 5 enhances the light conditions in the cutting room, thereby improving the accuracy of shooting.

[0037] Reference Figure 3 and Figure 4 In addition, there are impurities such as silicon mud in the cutting room. A glass protection sheet 6 corresponding to the first camera 3 and the second camera 4 is embedded in the detection housing 2 to protect the first camera 3 and the second camera 4 and the fill light source 5.

[0038] Reference Figure 2 The outer side of the detection housing 2 is provided with a rotary cover 7 corresponding to the glass protection sheet 6. The side of the rotary cover 7 is rotatably connected to the detection housing 2. When not shooting, the rotary cover 7 blocks the corresponding glass protection sheet 6 for protection; when shooting, the rotary cover 7 rotates along the rotation connection to avoid the glass protection sheet 6 to achieve shooting. The opening and closing of the two rotary covers 7 can be realized by components such as motors.

[0039] Reference Figure 3 In other embodiments, the two rotary covers 7 can be fixedly connected, and a rotating rod 71 is rotatably connected at the connection. The rotating rod 71 passes through the detection shell 2 and is rotatably connected to the detection shell 2. A rotating motor 72 is installed in the detection shell 2. The output shaft of the rotating motor 72 is fixedly connected to the rotating rod 71. The opening and closing of the two rotary covers 7 are synchronously controlled by the rotating rod 71.

[0040] The implementation principle of the device for detecting the oblique tension of the emery wire in a photovoltaic pay-off room according to an embodiment of the present application is as follows: when the winding roller switches between winding and paying out, the rotary cover 7 opens, and the first camera 3 and the second camera 4 take photos. The offset of the emery wire during the winding and unwinding process is detected through the photos, and the speed of the guide wheel along the moving track is controlled according to the offset, so as to reduce the angle of the emery wire on the winding roller and reduce the possibility of the emery wire breaking.

[0041] Embodiment 2:

[0042] Reference Figure 5 The difference between the second embodiment and the first embodiment is that a control module is further added, and the control module is a controller, which is electrically connected to the driving motor, the moving motor, the first camera 3, the second camera 4, the fill light source 5 and the rotating motor 72 respectively.

[0043] When the winding roller switches between winding and unwinding, the direction of the driving motor changes. After receiving the signal that the driving motor has changed direction, the controller controls the output shaft of the rotating motor 72 to rotate ninety degrees, and the rotary cover 7 opens. After the controller controls the rotary cover 7 to open, it controls the fill light source 5 to turn on. After the controller controls the fill light source 5 to turn on, it controls the first camera 3 and the second camera 4 to capture images. The controller receives and analyzes the image capture photos of the first camera 3 and the second camera 4, calculates the offset of the emery wire, and controls the moving motor according to the offset, controls the speed of the guide wheel along the moving track, reduces the angle of the emery wire on the winding roller, and reduces the possibility of the emery wire breaking. After the adjustment of the guide wheel moving speed is completed, the controller controls the output shaft of the rotating motor 72 to rotate ninety degrees in the opposite direction, and the rotary cover 7 is closed.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
