Description

Technical Field

[0001] The present application relates to the field of laser processing technology, and in particular to a detection device and detection equipment. Background Art

[0002] After the holes are punched in the roll using the laser beam, the roll needs to be inspected to check whether the positions of the holes in the roll are accurate.

[0003] At present, the inspection equipment generally includes a material pulling device, a visual inspection component, a positioning device and a material unloading device. The unloading device is used to unload the coil, and the positioning device is used to limit the position of the coil so that the coil is limited to the inspection area of ​​the visual inspection component. The visual inspection component is used to detect the position of the circular hole on the coil to determine whether the position accuracy of the circular hole meets the processing requirements. The material pulling device is used to pull the coil so that the visual component can continuously detect the circular hole on the coil.

[0004] The length of the pulled material coil is calculated based on the pulling device. However, due to errors in the pulling device when pulling the material, the length of the coil calculated based on the pulling device is inaccurate, which in turn affects the detection accuracy of the visual inspection component for the position of the circular holes on the coil.

[0044] The embodiments of the present application provide a detection device and a detection equipment for solving the technical problem of low detection accuracy of coiled materials.

[0045] In the embodiments of the present application, Figure 1 As shown, the detection device includes a base 1, a first roller 2, a second roller 3, a visual detection component 4, a sliding member 5, a first sensor 6 and a second sensor 7. The first roller 2 and the second roller 3 are both rotatably arranged at the top of the base 1, and the second roller 3 is arranged above the first roller 2 at intervals. The visual detection component 4 is arranged at the top of the base 1, and the visual detection component 4 is used to detect the coiled material. The sliding member 5 is slidably arranged on the side of the base 1 along the up and down directions. The first sensor 6 and the second sensor 7 are both arranged on the side of the base 1, and the first sensor 6 and the second sensor 7 are both used to detect the sliding member 5, and the second sensor 7 is arranged above the first sensor 6 at intervals.

[0046] In this embodiment, the base 1 can be a rack or a cabinet. When the detection device is used, the base 1 is generally placed on a horizontal ground.

[0047] In this embodiment, a laser beam may be used to punch holes in the coiled material. The visual inspection component 4 may be used to inspect the position accuracy of the circular holes in the coiled material.

[0048] like Figure 1 As shown, the process of detecting the coiled material by the detection device in the first embodiment is now described in detail:

[0049] The coiled material is placed on an unwinding device, and then the unrolled material is wound around the bottom of the sliding member 5, and then the material is passed through the gap between the first roller 2 and the second roller 3. At this time, the first roller 2 and the second roller 3 can press the material tightly, so when at least one of the first roller 2 and the second roller 3 rotates, the friction between the first roller 2 and the second roller 3 drives the material to move forward, thereby pulling the material.

[0050] The length of the coil conveyed by the first roller 2 and the second roller 3 can be calculated by the rotation angle and diameter of the first roller 2 or the second roller 3. The distance between the position of the first sensor 6 and the position of the second sensor 7 can be measured, and the length of the coil unrolled by the unwinding device can be calculated based on the distance between the detection position of the first sensor 6 and the detection position of the second sensor 7 of the slider 5.

[0051] The distance between the position of the first sensor 6 and the position of the second sensor 7 is defined as L.

[0052] The first roller 2 and the second roller 3 are controlled to convey a coil of L length, and the unwinding device is controlled to stop unwinding. At this time, the sliding member 5 will move upward from the detection position of the first sensor 6 toward the detection position of the second sensor 7 driven by the coil.

[0053] When the unwinding device is controlled to unwind the coil, the first roller 2 and the second roller 3 are controlled to stop conveying the coil. At this time, the slide 5 will drive the coil to move downward from the detection position of the second sensor 7 to the detection position of the first sensor 6 under the action of its own gravity.

[0054] Since the unwinding device unwinds the coil and the first roller 2 and the second roller 3 convey the coil independently, theoretically, the length L of the coil unwinded by the unwinding device each time is the same as the length of the coil conveyed by the first roller 2 and the second roller 3 each time. However, due to slight slippage between the first roller 2 and the second roller 3 and the coil, the unwinding device also slips when unwinding, and there is also a control error, so the actual length L of the coil unwinded by the unwinding device each time is different from the actual length of the coil conveyed by the first roller 2 and the second roller 3 each time.

[0055] In this embodiment, the first roller 2 and the second roller 3 are controlled to convey the coil, and the unwinding device is controlled to stop unwinding. When the slider 5 moves from the detection position of the first sensor 6 to the detection position of the second sensor 7, the first roller 2 and the second roller 3 are controlled to stop conveying the coil, and the time t1 required for the slider 5 to move from the detection position of the first sensor 6 to the detection position of the second sensor 7 is recorded.

[0056] Then the first roller 2 and the second roller 3 are controlled to stop conveying the coiled material, and the unwinding device is controlled to unwind the coiled material. When the slide 5 falls from the detection position of the second sensor 7 to the detection position of the first sensor 6, the unwinding device is controlled to stop unwinding the material, and the time t2 required for the slide 5 to fall from the detection position of the second sensor 7 to the detection position of the first sensor 6 is recorded.

[0057] By adjusting the speed of the unwinding device unwinding the coil so that t2=t1, the actual speed of the first roller 2 and the second roller 3 conveying the coil is made the same as the actual speed of the unwinding device unwinding the coil, so as to improve the length accuracy of the coil conveyed by the first roller 2 and the second roller 3, thereby improving the accuracy of the visual inspection component 4 in detecting the coil.

[0058] The first roller 2 and the second roller 3 of the embodiment of the present application are both rotatably arranged at the top of the base 1, and the second roller 3 is arranged above the first roller 2 at an interval, so that after the unfolded coil is inserted into the gap between the first roller 2 and the second roller 3, the coil can be conveyed through the first roller 2 and the second roller 3; the visual detection component 4 is arranged at the top of the base 1, and is used to detect the coil conveyed by the first roller 2 and the second roller 3 to determine whether the processing error of the coil is within the allowable range; the sliding member 5 is slidably arranged on the side of the base 1 in the up and down directions, and the first sensor 6 and the second sensor 7 are both arranged on the side of the base 1, and The second sensor 7 is arranged above the first sensor 6 at intervals, so that when the slider 5 slides freely in the up and down directions, the first sensor 6 and the second sensor 7 can detect the position of the slider 5; the unfolded coil is wound around the slider 5 from the bottom of the slider 5, so that the coil can drive the slider 5 to move upward, or the slider 5 drives the coil downward under the action of its own gravity; therefore, when the coil is conveyed by the first roller 2 and the second roller 3, the sliding position of the slider 5 in the up and down directions adjusts the length accuracy of the coil actually conveyed by the first roller 2 and the second roller 3, so as to improve the accuracy of the visual inspection component 4 in detecting the coil.

[0059] In one embodiment, if Figure 1 As shown, the visual inspection component 4 includes a support frame 41 and a camera 42. The support frame 41 is arranged at the top of the base 1, and the camera 42 is arranged on the support frame 41. The camera 42 is used to capture the coil. By comparing the image information of the coil captured by the camera 42 with the preset image information, it is determined whether the processing error of the coil is within the allowable range.

[0060] In one embodiment, if Figure 1 As shown, the visual inspection assembly 4 further includes a light source 43, which is disposed on the support frame 41 and is located below the camera 42; wherein an avoidance channel is disposed on the light source 43, and the avoidance channel is used for the camera 42 to capture the web. The light source 43 is used to illuminate the web to improve the clarity of the web captured by the camera 42.

[0061] In one embodiment, if Figure 1 As shown, the detection device further includes a driver 8, which is disposed at the top of the base 1, and the first roller 2 is connected to the output end of the driver 8, and the driver 8 is used to drive the first roller 2 to rotate. The driver 8 can conveniently control the rotation angle of the first roller 2, so as to facilitate the control of the rotation or stop of the first roller 2 according to the position of the sliding member 5 detected by the first sensor 6 and the second sensor 7.

[0062] In one embodiment, if Figure 1 and Figure 2As shown, the detection device further includes a transmission belt 9, and a plurality of first rollers 2 and second rollers 3 are provided, and the first rollers 2 and second rollers 3 are provided one by one, and the transmission belt 9 is tensioned on two adjacent first rollers 2. By tensioning the transmission belt 9 on two adjacent first rollers 2, the plurality of first rollers 2 can be rotated synchronously, so that the first rollers 2 can convey the coiled material synchronously. By providing a plurality of first rollers 2 and second rollers 3, the coiled material can be flattened, so that the visual detection component 4 can detect the coiled material, and the detection error of the visual detection component 4 can be reduced. It can also improve the accuracy of conveying the coiled material and reduce the probability of slipping.

[0063] In one embodiment, if Figure 1 and Figure 2 As shown, the first rollers 2 are arranged at intervals in the horizontal direction so as to flatten the coil in the horizontal plane, thereby improving the detection accuracy of the visual detection component 4.

[0064] In one embodiment, if Figure 1 and Figure 2 As shown, the detection device further includes a support plate 10, which is disposed between two adjacent first rollers 2, and is located in the detection area of ​​the visual detection component 4, and the heights of both ends of the support plate 10 are respectively the same as the heights of the first rollers 2 at both ends of the support plate 10. Since the two adjacent first rollers 2 are disposed at intervals, the coil can be supported by the support plate 10, and the coil can be prevented from sagging due to its own gravity, thereby improving the accuracy of the visual detection component 4 in detecting the coil.

[0065] In one embodiment, if Figure 1 and Figure 2 As shown, the detection device further includes a mounting frame 20 and a tensioning wheel 30. The mounting frame 20 is arranged at the top of the base 1, and the first roller 2, the second roller 3 and the tensioning wheel 30 are all rotatably arranged on the mounting frame 20. The tensioning wheel 30 abuts against the transmission belt 9.

[0066] The tensioning wheel 30 abuts against the transmission belt 9 to tension the transmission belt 9 through the tensioning wheel 30 , so that two adjacent first rollers 2 can rotate synchronously to avoid slipping between the transmission belt 9 and the first rollers 2 .

[0067] In one embodiment, if Figure 1 As shown, the distance between the tensioning wheel 30 and the transmission belt 9 is adjustable, so that the user can adjust the tension of the tensioning wheel 30 to tension the transmission belt 9 according to actual usage.

[0068] In one embodiment, if Figure 1As shown, the distance between the second roller 3 and the first roller 2 is adjustable. So that the user can adjust the distance between the second roller 3 and the first roller 2 according to the thickness of the coiled material, so that the first roller 2 and the second roller 3 can press the coiled material to realize the conveying of the coiled material, and reduce the probability of slipping between the first roller 2 and the second roller 3 and the coiled material. Coils of different thicknesses can also be conveyed by adjusting the distance between the second roller 3 and the first roller 2.

[0069] In one embodiment, if Figure 1 and Figure 2 As shown, the detection device further includes a mounting frame 20, a fixing seat 40 and an adjusting member 50. The mounting frame 20 is disposed at the top of the base 1, and the first roller 2 is rotatably disposed on the mounting frame 20. The fixing seat 40 is disposed in the mounting frame 20, and the second roller 3 is rotatably disposed on the fixing seat 40. The adjusting member 50 is threadedly connected to the mounting frame 20, and the end of the adjusting member 50 is fixedly connected to the fixing seat 40, so that the second roller 3 is moved closer to or away from the first roller 2 by rotating the adjusting member 50.

[0070] The adjusting member 50 is threadedly connected to the mounting frame 20, and the end of the adjusting member 50 is fixedly connected to the fixing seat 40. When the adjusting member 50 is rotated, the fixing seat 40 can be driven by the adjusting member 50 to move closer to or farther from the first roller 2. The second roller 3 is rotatably disposed on the fixing seat 40, so the second roller 3 can be moved closer to or farther from the first roller 2 by rotating the adjusting member 50, thereby adjusting the distance between the second roller 3 and the first roller 2.

[0071] In this embodiment, the adjusting member 50 may be a screw.

[0072] In one embodiment, if Figure 2 and Figure 3 As shown, a limiting hole 51 is provided on the sliding member 5, and the limiting hole 51 is used for the coil to pass through. The hole wall of the limiting hole 51 can limit the coil to prevent the coil from escaping from the limiting hole 51.
