As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.
[0024] The present application will be further described below with reference to the drawings and specific embodiments:
[0025] As shown in Figure 1 , 2 A punched leather roll detection device, comprising a rack 1, the feeding side and the discharging side of the rack 1 are respectively provided with a unwinding assembly 2 and a winding assembly 3, a visual recognition device and a marking device are sequentially arranged on the rack 1 in the direction away from the unwinding assembly 2, a punched leather 100 is arranged below the visual recognition device, both ends of the punched leather 100 are wound on the unwinding assembly 2 and the winding assembly 3 respectively, the visual recognition device is used for detecting whether there is a blocked hole or a missed hole on the punched leather 100, and the marking device is used for marking the position of the missed hole or the blocked hole on the punched leather 100.
[0026] The visual recognition device comprises a camera assembly 4 and an industrial control host computer (not shown in the figure), and the industrial control host computer is electrically connected with the camera assembly 4, the unwinding assembly 2, the winding assembly 3 and the marking device.
[0027] In this embodiment, the punched leather 100 in the conveying process is tensioned and controlled under the action of the winding assembly 3 and the unwinding assembly 2, so that the punched leather 100 passing through the visual recognition device and the marking device is effectively flattened.
[0028] In this embodiment, during work, the punched leather 100 passes through the visual identification device and the marking device under the action of the winding assembly 3 and the unwinding assembly 2 according to the set winding speed. First, the camera assembly 4 takes high-speed continuous photos of the passing punched leather 100, and then the acquired actual photos are compared and analyzed with the contrast photos built in the industrial host (with CCD software built in). If the number of holes in the actual photos is consistent with that in the contrast photos, it means that there is no blocked hole or missing hole, and it is determined to be qualified, so the marking device does not need to work. If the number of holes in the actual photos is inconsistent with that in the contrast photos, it means that there is a blocked hole or a missing hole, and at the same time, the marking device is controlled to work to mark the position of the blocked hole or the missing hole, so that the staff can quickly find the position of the blocked hole or the missing hole on the punched leather 100, so as to facilitate quick observation and later process maintenance.
[0029] The above structure is accurate, efficient and practical in detection, and greatly improves the product qualification rate and production line production efficiency.
[0030] In this embodiment, the visual identification device further includes a display, a keyboard and a mouse to meet the user's observation, research and analysis of the blocked hole or missing hole on the display.
[0031] Further, as shown in Figure 1 , 2 , the visual identification device further includes a light source 5 and a projection plate 6 connected with the rack 1. The projection plate 6 is arranged between the punched leather 100 and the camera assembly 4, and the light source 5 is arranged below the punched leather 100 with the light emitting direction towards the punched leather 100.
[0032] In this embodiment, the light passes through the holes of the punched leather 100 and projects on the projection plate 6, forming a plurality of dot-shaped projections on the projection plate 6. Then the camera assembly 4 takes continuous photos of the projection plate 6, and then the acquired actual photos are compared and analyzed with the contrast photos built in the industrial host. Compared with the prior art of taking photos of the whole punched leather 100 for comparison, the influence of more external factors is reduced, and the identification of blocked holes or missing holes of the punched leather 100 is more accurate and reliable.
[0033] Further, as shown in Figure 1 , 2 , the marking device includes a first marking mechanism 7 arranged between the camera assembly 4 and the winding assembly 3. The first marking mechanism 7 is connected with the rack 1, and is used to mark the vertical column of the blocked hole or the missing hole on the punched leather 100.
[0034] Further, as shown in Figure 2 , the first marking mechanism 7 includes a first lifting driving mechanism 71 fixedly connected with the rack 1, and a first marking pen 72 connected with the driving end of the first lifting driving mechanism 71.
[0035] In this embodiment, by the arrangement of the first marking mechanism 7, compared with the prior art large range searching for the blocked hole or the missing hole, the searching range is reduced, the vertical column where the blocked hole or the missing hole is located can be quickly found, thereby reducing the difficulty of the subsequent process maintenance and improving the efficiency of the subsequent process maintenance.
[0036] Further, as shown in Figure 2 , the marking device further comprises a second marking mechanism 8 close to the discharging side of the rack 1, the second marking mechanism 8 is connected with the rack 1, and the second marking mechanism 8 is used for identifying the position of the blocked hole or the missing hole on the punched leather 100.
[0037] Further, as shown in Figure 2 , the second marking mechanism 8 comprises a second marking pen 81 and a front-rear driving mechanism 82, the front-rear driving mechanism 82 is connected with the rack 1, a second lifting driving mechanism 83 is arranged on the front-rear driving mechanism 82, and the second marking pen 81 is connected with the driving end of the second lifting driving mechanism 83.
[0038] In this embodiment, during work, first, the camera assembly 4 takes a photo of the passing punched leather 100, when it is found that there is a blocked hole or a missing hole after identification and judgment, the first marking mechanism 7 is controlled to make identification on the vertical column where the blocked hole or the missing hole is located, at the same time, the front-rear driving mechanism 82 drives the second marking pen 81 to the horizontal row where the blocked hole or the missing hole is located, then when the vertical column where the blocked hole or the missing hole is located is rewound below the second marking pen 81, the second lifting driving mechanism 83 drives the second marking pen 81 to make identification by clicking down (since the punching speed of the punched leather 100 is fixed, the time when the corresponding vertical column to be identified reaches below the second marking pen 81 after the first marking mechanism 7 acts can be used to control the action of the second lifting driving mechanism 83); in the above structure, through the combined design of the first marking mechanism and the second marking mechanism, the position of the blocked hole or the missing hole on the punched leather 100 can be accurately and quickly identified.
[0039] Further, as shown in Figure 1 , 2 In order to improve the detection reliability and meet the detection of the blocked hole or the missing hole of the punched leather 100 with a larger width, the camera assembly 4 comprises a plurality of CCD cameras 41 distributed from front to back, and the CCD cameras 41 are connected with the rack 1 through the connecting plate 10.
[0040] In this embodiment, the number and spacing of the CCD cameras 41 can be adjusted according to the width of the punched leather 100.
[0041] Further, as shown in Figure 1 , the rack 1 is further provided with an alarm 9, and the alarm 9 is electrically connected with the industrial computer.
[0042] In this embodiment, in order to issue an alarm information to remind the user when a blocked hole or a leaking hole is detected.
[0043] Further, the alarm 9 is one or a combination of a sound alarm 9 or a light alarm 9.
