Description

Technical Field

[0001] The present application relates to the technical field of label detection, and in particular to an automatic line drawing device. Background Art

[0002] A label is an identifier used to identify, classify and describe things. It can be a small piece of paper, plastic or other material with words, patterns or symbols printed on it to identify and classify items. Labels usually consist of words, numbers, letters or symbols to distinguish and identify different objects or concepts. In daily life, labels are widely used to classify, identify and manage goods, documents, luggage, etc.

[0003] At present, during the production process of labels, there are often defective labels with poor printing. Machine equipment will be used to identify them, and workers will mark the defective products by drawing lines to avoid sticking defective products on the goods.

[0004] Regarding the above-mentioned related technologies, after the recognition equipment detects, manual line drawing is required. This marking method is relatively cumbersome, and the manual marking speed is slow and difficult to adapt to the machine detection speed, which affects the detection efficiency and has a lot of room for improvement. Utility Model Content

[0005] In order to improve the detection efficiency of labels, the present application provides an automatic line drawing device.

[0008] Through the above technical solution, the label is inspected by the visual inspection mechanism while being transported by the transmission mechanism. After the defective label is detected, the control cabinet controls the drawing mechanism to approach the label, and a line is drawn on the moving defective label to distinguish the defective products. Compared with traditional manual line drawing, the line drawing device has a higher overall degree of automation and continuous movements, which effectively improves the inspection efficiency of the label.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses an automatic line drawing device. Figure 1 The marking device includes a frame 1, a visual inspection mechanism 2, a marking mechanism 3 and a control cabinet. The marking mechanism 3 is installed on the frame 1 and is adjacent to the label. The visual inspection mechanism 2 is installed on the frame 1 to detect defective products in the label. The control cabinet controls the movement of the marking mechanism 3 to draw lines on the defective products.

[0033] refer to Figure 1 The produced labels are not cut, and several labels are connected together. The labels are rolled up by the upstream winding device for subsequent cutting. Since the transmission distance of the labels is too long, the labels may sag during the transmission process, resulting in loose winding. Therefore, a transmission component 4 is provided, and the transmission component 4 is installed on the frame 1. Specifically, the transmission component 4 includes a supporting roller 41 and a transmission roller 42, wherein one end of the supporting roller 41 has a boss, and the boss is fixedly installed on the frame 1 by screws, and a bearing is sleeved and installed on the roller body of the supporting roller 41, and the inner ring of the bearing and the roller body of the supporting roller 41 are relatively stationary; a through hole is opened inside the transmission roller 42, and the transmission roller 42 is sleeved and installed on the outside of the supporting roller 41, and the outer ring of the bearing abuts against the transmission roller 42 and is relatively stationary, and the transmission roller 42 can rotate outside the supporting roller 41, and the label passes around the transmission roller 42, and the rotating component supports the label, so that the label is in a taut state, which is conducive to the winding of the label.

[0034] refer to Figure 1 In the process of label transmission, the label quality inspection and line marking can be carried out simultaneously. After the label is rolled up, the defective products and qualified products can be separated and classified in the subsequent cutting process. Therefore, a visual inspection mechanism 2, a control cabinet and a line drawing mechanism 3 are set. The visual inspection mechanism 2 and the line drawing mechanism 3 are electrically connected to the control cabinet respectively. Specifically, the visual inspection mechanism 2 includes a light source, a sensor and an industrial camera, wherein the light source is projected on the label, and the shooting range of the industrial camera is consistent with the projection area of ​​the light source. The industrial camera will take pictures of the labels during the transmission process, and the sensor scans the original image of the label and determines whether it is different from the qualified product. If it is different from the qualified product, it is a defective product; when the sensor detects a defective label, it will generate a signal and send the signal to the control cabinet, and the control cabinet will then generate a control signal to control the line drawing mechanism 3 to start and draw lines on the defective label. The visual inspection mechanism 2 and the control cabinet are not specifically displayed in the drawings of the specification.

[0035] refer to Figure 1 and Figure 2The marking mechanism 3 is installed on the frame 1 and is adjacent to the label being transmitted. Specifically, the marking mechanism 3 includes a supporting member 31, a telescopic member 32 and a brush 33. The supporting member 31 is installed on the frame 1, the telescopic member 32 is fixedly installed on the supporting member 31, and the brush 33 is fixedly installed on the supporting member 31, wherein the supporting member 31 is a plate-like structure, providing an installation position for the telescopic member 32. In this embodiment, the telescopic member 32 is a first telescopic cylinder, which is fixedly installed on the supporting member 31, and the brush 33 is installed on the telescopic rod of the first telescopic cylinder, and the telescopic rod of the first telescopic cylinder is arranged perpendicular to the label. The first telescopic cylinder drives the brush 33 to extend perpendicular to the label, and the tip of the brush 33 contacts the surface of the defective label being transmitted, and the tip of the brush abuts against the transmission roller 42 through the label, so that the brush 33 leaves a clear line on the defective label.

[0036] refer to Figure 2 Since the widths of the labels produced are different, if the position of the brush 33 is fixed, it cannot meet the marking requirements of defective labels of different widths. Therefore, an adjusting member 5 is also provided. Specifically, the adjusting member 5 includes a slide rail 51 and a slider 52, wherein the slide rail 51 is fixedly mounted on the telescopic rod of the first telescopic cylinder, and the setting direction of the slide rail 51 is parallel to the width direction of the label; the slider 52 is a block structure, which is slidably mounted on the slide rail 51 and moves along the slide rail 51. The brush 33 is fixedly mounted on the slider 52. The brush 33 is fixedly mounted on the slider 52, thereby being arranged on the first telescopic cylinder. At the same time, a threaded fastener is also provided on the slider 52, which passes through the slide rail 51 and is threadedly connected to the slider 52. After the brush 33 is adjusted to a suitable marking position, the threaded fastener can be tightened to fix the slider 52 to the slide rail 51. When the position of the brush 33 needs to be adjusted, the threaded fastener is loosened, and then the position of the slider 52 is adjusted, thereby improving the practicality of the marking mechanism 3.

[0037] refer to Figure 2 In order to make the drawn marking line more obvious, a marker pen is usually used for marking. However, the tip of the marker pen is exposed to the air for a long time, and the ink is easy to evaporate, which greatly shortens the service life of the marker pen. Therefore, a sealing component 6 is also provided to seal the brush 33. Since the telescopic member 32 is arranged perpendicular to the label and the brush 33 is facing the label, it is not convenient for the sealing component 6 to seal the tip of the brush. Therefore, the sealing component 6 is arranged on the frame 1 and is adjacent to the supporting member 31. The supporting member 31 is rotatably installed on the frame 1. When the brush 33 finishes drawing the line, the telescopic rod of the first telescopic cylinder retracts, driving the brush 33 away from the label, and then the supporting member 31 rotates. After the rotation, the brush 33 is parallel to the label, and the tip of the brush 33 is facing the sealing component 6.

[0038] Specifically, the sealing assembly 6 includes a power element 61 and a pen cap 62. The pen cap 62 is arranged on the power element 61. In the present embodiment, the power element 61 is a second telescopic cylinder. The second telescopic cylinder is adjacent to and opposite to the first telescopic cylinder, that is, the telescopic rod of the first telescopic cylinder and the telescopic rod of the second telescopic cylinder can be extended relative to each other; the pen cap 62 is fixedly installed on the telescopic rod of the second telescopic cylinder. When the supporting member 31 drives the paintbrush 33 to rotate into place, the telescopic rod of the second telescopic cylinder drives the pen cap 62 to extend and covers the pen cap 62 on the paintbrush 33, thereby effectively reducing the possibility of ink volatilization of the paintbrush 33 and extending the service life of the paintbrush 33.

[0039] refer to Figure 2 and Figure 3 In order to control the rotation of the supporting member 31, a tension element 7 is also provided. The tension element 7 is rotatably arranged on the frame 1 and is rotatably connected to the supporting member 31. Specifically, in the present embodiment, the tension element 7 is a third telescopic cylinder. The end of the third telescopic cylinder away from the telescopic rod is rotatably mounted on the frame 1 through the first rotating shaft. The telescopic rod of the third telescopic cylinder is rotatably mounted on the supporting member 31 through the second rotating shaft. The supporting member 31 is rotatably mounted on the frame 1 through the third rotating shaft, and the third rotating shaft is located between the first rotating shaft and the second rotating shaft. The telescopic direction of the telescopic rod of the third telescopic cylinder is perpendicular to the axial directions of the first rotating shaft, the second rotating shaft and the third rotating shaft. When the telescopic rod of the third telescopic cylinder is retracted, the paintbrush 33 is perpendicular to the label. When the telescopic rod of the third telescopic cylinder is extended, the tip of the paintbrush 33 is facing the pen cover 62. The rotation of the supporting member 31 is controlled by the extension and retraction of the telescopic rod of the third telescopic cylinder. The rotation process is fast and efficient.
