[0038] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0039] The following describes in detail, with reference to the accompanying drawings, the specific structure of a metal wire mesh detection device 1 provided by this utility model and its corresponding technical effects.
[0040] It should be noted that in this embodiment, the height direction described below is perpendicular to the preset direction, and the height direction is perpendicular to the movement direction of the metal wire mesh woven in the metal wire mesh weaving device.
[0041] Please refer to Figures 1-3 The present invention provides a metal wire mesh detection device 1 comprising a frame 100, a drive module 200, and a detection module 300. The frame 100 defines an installation space, the drive module 200 is mounted on the frame 100, and the detection module 300 is connected to the drive module 200. The drive module 200 can drive the detection module 300 to move relative to the frame 100 in a preset direction.
[0042] The installation space is used to place the wire mesh weaving device 2. That is, when the wire mesh detection device 1 detects the defects of the wire mesh 201 woven by the wire mesh weaving device 2, the wire mesh weaving device 2 is at least partially in the installation space, and the wire mesh 201 woven by the wire mesh weaving device 2 passes through the installation space.
[0043] Furthermore, in this embodiment, the metal wire mesh detection device 1 and the metal wire mesh weaving device 2 can be installed independently or detachably connected. That is, the metal wire mesh detection device 1 and the metal wire mesh weaving device 2 can be separated, and the metal wire mesh detection device 1 can be replaced with different metal wire mesh weaving devices 2 to detect defects in the woven metal wire mesh 201.
[0044] The detection module 300 is used to move in a preset direction to acquire surface image information of the metal wire mesh 201 woven by the metal wire mesh weaving device 2, so as to detect surface defects of the woven metal wire mesh 201. It should be noted that the detection module 300 may include a CCD camera. After acquiring the surface image information of the metal wire mesh 201, the detection module 300 can detect common defects such as broken warp, broken weft, knotted wire, opening marks, mechanical segments, oil stains, holes, and loose weave on the metal wire mesh 201, thereby reducing the possibility of missed detections during the detection of defects in the metal wire mesh 201.
[0045] Optionally, the metal wire mesh detection device 1 provided in this embodiment may further include a judgment module, which can determine whether the metal wire mesh 201 is qualified based on the image information of the metal wire mesh 201 obtained by the detection module 300.
[0046] In detail, in this embodiment, the frame 100 includes a first bracket 110, a second bracket 120 and a mounting frame 130. The first bracket 110 and the second bracket 120 are arranged at intervals along a preset direction. The two ends of the mounting frame 130 are respectively connected to the first bracket 110 and the second bracket 120. The extension direction of the mounting frame 130 is the same as the preset direction. The drive module 200 and the detection module 300 are both mounted on the mounting frame 130.
[0047] In other words, the first bracket 110 and the second bracket 120 are used to support the mounting frame 130. The first bracket 110 and the second bracket 120 are placed at the installation position according to the operation requirements. For example, the first bracket 110 and the second bracket 120 are placed on both sides of the wire mesh weaving device 2, and the mounting frame 130 is located on the top of the wire mesh weaving device 2.
[0048] Optionally, in some embodiments, the first bracket 110 and the second bracket 120 can drive the mounting frame 130 to move in the height direction. That is, the first bracket 110 has a first support end 111 and a first adjustment end 112 that are opposite each other in the height direction, and the second bracket 120 has a second support end 121 and a second adjustment end 122 that are opposite each other in the height direction. The first support end 111 and the second support end 121 are respectively installed at the installation position, and the two ends of the mounting frame 130 are respectively connected to the first adjustment end 112 and the second adjustment end 122. The first adjustment end 112 and the second adjustment end 122 can move in the height direction.
[0049] Understandably, a hydraulic cylinder can be installed in the first bracket 110, and the first adjusting end 112 is connected to the driving end of the hydraulic cylinder on the first bracket 110. Similarly, a hydraulic cylinder can also be installed in the second bracket 120, and the second adjusting end 122 is connected to the hydraulic cylinder on the second bracket 120. Through the two hydraulic cylinders, the first adjusting end 112 and the second adjusting end 122 can be driven to move in the height direction, respectively.
[0050] Of course, in some other embodiments, the first adjustment end 112 and the second adjustment end 122 can also move in the height direction in other ways to adjust the position of the mounting bracket 130 in the height direction. The adjustment methods of the first adjustment end 112 and the second adjustment end 122 will not be described in detail here.
[0051] Understandably, when the metal wire mesh detection device 1 detects the metal wire mesh 201 woven by the metal wire mesh weaving device 2, it is necessary to adjust the first adjustment end 112 and the second adjustment end 122 to make the mounting frame 130 horizontal, thereby adjusting the parallelism, height, distance, etc. between the detection module 300 and the metal wire mesh 201.
[0052] Understandably, since the mounting bracket 130 can adjust its position in the height direction through the first adjustment end 112 and the second adjustment end 122, it can adjust the height of the installation space to accommodate metal wire braiding devices of different sizes.
[0053] In this embodiment, the frame 100 is equipped with casters 140. Specifically, both the first support end 111 and the second support end 121 are equipped with casters 140. The casters 140 facilitate the movement of the frame 100 by the operators.
[0054] Optionally, the mounting bracket 130 can be detachably connected to the first bracket 110 and the second bracket 120. The detachable connection can be made in ways including, but not limited to, threaded fastener connection or plug-in connection. Understandably, because the mounting bracket 130 can be detachably connected to the first bracket 110 and the second bracket 120, operators can change the spacing between the first bracket 110 and the second bracket 120 in a preset direction according to the dimensions of different sizes of wire braiding devices in a preset direction, and install a mounting bracket 130 of a suitable size.
[0055] Please refer to Figures 4-8 The drive module 200 includes a drive component 210 and a guide rail 220, both mounted on the frame 100. The guide rail 220 extends along a preset direction. The detection module 300 is mounted on the guide rail 220. The drive component 210 is connected to the detection module 300. The drive component 210 can drive the detection module 300 to move on the guide rail 220. By setting the guide rail 220, the detection module 300 can move relatively smoothly in the preset direction.
[0056] It should be noted that in this embodiment, both the drive component 210 and the guide rail 220 are mounted on the aforementioned mounting bracket 130. The drive component 210 can be detachably mounted on the mounting bracket 130 or non-detachably mounted on it. It is understood that when the drive component 210 is detachably mounted on the mounting bracket 130, it facilitates the installation and removal of the drive component 210 by operators. When the drive component 210 is non-detachably mounted on the mounting bracket 130, the assembly strength between the drive component 210 and the mounting bracket 130 is guaranteed.
[0057] Similarly, the guide rail 220 can be detachably mounted on the mounting bracket 130 or non-detachably mounted on the mounting bracket 130.
[0058] The aforementioned detachable method can be connected via snap-fit, threaded fasteners, or plug-in connection.
[0059] In detail, the drive module 200 also includes a timing belt 230 and a timing pulley 240. The timing pulley 240 and the drive component 210 are installed at intervals on the frame 100 along a preset direction. The drive component 210 includes a drive motor and a drive pulley connected to each other. The timing belt 230 is simultaneously fitted onto the drive pulley and the timing pulley 240. The rotation axes of the drive pulley, the timing belt 230 and the timing pulley 240 are parallel to the height direction. The detection module 300 is connected to the drive motor through the timing belt 230.
[0060] In detail, in this embodiment, the synchronous pulley 240 and the drive motor are installed at intervals on the mounting bracket 130 along a preset direction.
[0061] In other words, in this embodiment, during the process of the drive motor driving the synchronous belt 230 to rotate, the detection module 300 can be driven by the synchronous belt 230 to reciprocate between the synchronous pulley 240 and the drive pulley in a preset direction, and under the action of the guide rail 220, the detection module 300 can be guaranteed to move relatively stably in the preset direction.
[0062] Alternatively, in some other embodiments, the drive module 200 may not drive the detection module 300 to move in a preset direction via the timing belt 230 and timing pulley 240. For example, the drive module 200 may also be a linear actuator 210 such as a drive cylinder or a lead screw motor.
[0063] In this embodiment, the detection module 300 includes a mounting block 310 and a detection camera 320 connected to each other. The mounting block 310 is detachably connected to the drive module 200. Specifically, in this embodiment, the mounting block 310 is detachably connected to the guide rail 220 and the timing belt 230. The mounting block 310 is clamped to the timing belt 230 by a clamping component. The mounting block 310 slides with the guide rail 220. Of course, the mounting block 310 can also roll with the guide rail 220.
[0064] The mounting block 310 has a strip-shaped mounting hole extending along the height direction. That is, when the mounting block 310 is installed on the guide rail 220 and connected to the timing belt 230, the strip-shaped mounting hole on the mounting block 310 extends along the height direction. The detection camera 320 is installed on the mounting block 310 through fasteners and the strip-shaped mounting hole. The detection camera 320 can adjust its height position on the mounting hole through the strip-shaped mounting hole.
[0065] The metal wire mesh detection device 1 also includes a pressure roller assembly 400, which includes a connector 410, a pressure roller 430 and an encoder 420. The connector 410 is connected to the mounting bracket 130, the encoder 420 is connected to the connector 410, and the pressure roller 430 is connected to the encoder 420 and can rotate relative to the encoder 420. The pressure roller 430 is used to press onto the metal wire mesh 201.
[0066] In other words, when the wire mesh weaving device 2 is installed in the installation space of the wire mesh detection device 1, and the width direction of the wire mesh 201 woven by the wire mesh weaving device 2 is parallel to the preset direction, the pressure roller 430 can press it onto the wire mesh 201. When the wire mesh 201 woven by the wire mesh weaving device 2 moves along its own length direction, the wire mesh 201 can drive the pressure roller 430 to rotate. Since the pressure roller 430 is connected to the encoder 420, the encoder 420 can detect the running speed of the wire mesh 201, thereby detecting the weaving speed of the wire mesh.
[0067] In this embodiment, to avoid the external environment affecting the detection module 300's acquisition of surface image information of the metal wire mesh 201, the metal wire mesh detection device 1 further includes a cover 500. The cover 500 is mounted on the frame 100 and covers the drive module 200 and the detection module 300. Specifically, the cover 500 covers the mounting frame 130, and both the drive module 200 and the detection module 300 are located inside the cover 500. The opening of the cover 500 and the lens of the detection module 300 are both set downwards. In this embodiment, the mounting frame 130 has a clearance opening for the detection module 300, and the clearance opening extends along a preset direction.
[0068] The cover 500 is detachably mounted on the mounting bracket 130 to facilitate the installation and removal of the cover 500 by the operators.
[0069] Optionally, the metal wire mesh detection device 1 also includes a display module 600, which is communicatively connected to the detection module 300. Understandably, the display module 600 can display image information of the metal wire mesh 201 detected by the detection module 300.
[0070] Optionally, the metal wire mesh detection device 1 further includes a light source module (not shown in the figure), which is used to illuminate the surface of the metal wire mesh 201 woven by the metal wire mesh weaving device 2 so that the detection module 300 can acquire image information of the metal wire mesh 201. The light emitted by the light source module can be backlight or front light.
[0071] The light source module can be installed on the first bracket 110, the second bracket 120 or the mounting bracket 130. Of course, the light source module can also be installed on the metal wire mesh weaving device 2.
[0072] Optionally, the wire mesh detection device 1 may also include a cleaning bucket 700, which is installed on the outside of the wire mesh weaving device 2 to facilitate the placement of waste generated by the wire mesh weaving device 2 during the weaving of the wire mesh 201 by the operator.
[0073] In summary, the metal wire mesh detection device 1 provided in this embodiment includes a frame 100, a drive module 200, and a detection module 300. The frame 100 defines an installation space, the drive module 200 is mounted on the frame 100, and the detection module 300 is connected to the drive module 200. The drive module 200 can drive the detection module 300 to move relative to the frame 100 in a preset direction. When common defects such as broken warp, broken weft, knotted wire, opening marks, mechanical segments, oil stains, holes, and loose weave exist on the metal wire mesh 201, they can be detected by the detection module 300, thereby reducing the possibility of missed detections during the detection of defects in the metal wire mesh 201.
[0074] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
