Description

Technical Field

[0001] The present application relates to the field of label detection, and in particular to a label detection and positioning device. Background Art

[0002] A label is a small card, sticker or logo containing information that is attached to a product, package or other item. They provide important information about the item so that consumers, parties in the supply chain and regulators can understand and use this information. After the product is labeled, it needs to be inspected and verified to ensure the quality, accuracy and compliance of the label.

[0003] When a product is undergoing label inspection, it is generally necessary to transport the product to the inspection equipment via a conveyor belt. However, the product may be offset as it is transported along the conveyor belt, which may cause a certain tilt between the front position of the product label and the inspection end of the inspection equipment, reducing the overall accuracy of the label during inspection, thereby affecting the overall inspection efficiency of the label.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there is a defect that the detection position of the product with a label is offset during detection. Therefore, a label detection and positioning device is proposed to solve the above-mentioned problem. Utility Model Content

[0008] Preferably, the sliding mechanism includes a gear, which is installed at the rotating shaft in the middle of the bottom end of the movable frame. A fixed plate is fixedly installed on the upper surface of the conveying equipment near the fixed frame. One side of the fixed plate is threadedly connected to a limiting screw, and a rack plate is rotatably installed on one side of the limiting screw.

[0009] Preferably, sliding grooves are formed through the inner wall of the fixed frame at both upper and lower ends, and fixed protrusions are welded through the outer sides of the sliding grooves at both upper and lower ends of the movable block, and the sliding grooves and the fixed protrusions are interlocked.

[0010] Preferably, an open slot is provided on one side of the fixed frame, and the number of the baffle plates on one side of a single movable block is three, and the baffle plates and the open slot are adapted to each other.

[0011] Preferably, one end of the rack plate moves close to the outer surface of the gear, and the gear and the rack plate are meshed with each other.

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a label detection and positioning device. Figure 1-3A label detection and positioning device comprises a conveying device 1, a conveyor belt 2 is movably installed in the middle of the top of the conveying device 1, a label detector 3 is arranged on one side of the upper surface of the conveying device 1, a fixed frame 4 is symmetrically fixedly connected to the other side of the upper surface of the conveying device 1, a movable frame 5 is rotatably installed inside the fixed frame 4, a plurality of guide rollers 6 are rotatably installed inside the movable frame 5, a fixed frame 7 is fixedly installed on one side of the movable frame 5, a cylinder 8 is installed in the middle of one side of the outer surface of the fixed frame 7, an output end of one side of the cylinder 8 extends to the inside of the fixed frame 7 and a movable block 9 is installed, a plurality of baffle plates 10 are fixedly installed on one side of the movable block 9, an open groove is opened on one side of the fixed frame 7, the number of baffle plates 10 on one side of a single movable block 9 is three, the baffle plates 10 and the open groove are adapted to each other, and a sliding mechanism is also provided at the bottom of the fixed frame 4 for controlling the rotation angle of the movable frame 5.

[0020] By placing the product on the upper surface of the conveyor belt 2 for conveying, the product is moved close to the label detector 3 for label detection, the movable frame 5 is rotated along the inside of the fixed frame 4, and then the two movable frames 5 are rotated to adjust the spacing, so that the movable frame 5 is suitable for products of different sizes, and the products on the edge of the conveyor belt 2 are guided to the center by the guide roller 6, and the cylinder 8 is started to push the movable block 9 to move along the inside of the fixed frame 7, and the fixed protrusion 12 is moved along the inside of the sliding groove 11, keeping the movable block 9 in a stable movable state inside the fixed frame 7, so that the movable block 9 pushes the baffle plate 10 to slide out along the inside of the fixed frame 7 to block the product, and then the product can be conveyed along the middle position of the upper surface of the conveyor belt 2, and the label detector 3 detects the label on the product being conveyed, which reflects the diversion effect of the product on the conveyor belt 2.

[0021] Reference Figure 1 and Figure 3 The sliding mechanism includes a gear 13, which is installed at the rotating shaft in the middle of the bottom end of the movable frame 5. A fixed plate 14 is fixedly installed on the upper surface of the conveying equipment 1 near the fixed frame 4. A limiting screw 15 is threadedly connected to one side of the fixed plate 14. A rack plate 16 is rotatably installed on one side of the limiting screw 15. One end of the rack plate 16 moves close to the outer surface of the gear 13, and the gear 13 and the rack plate 16 are meshed with each other.

[0022] By rotating the limit screw 15 to move along the outer surface of the fixing plate 14 , the limit screw 15 pushes the rack plate 16 to move along the outer surface of the gear 13 , so that the rack plate 16 adjusts the gear 13 to rotate, reflecting the position adjustment effect of the rack plate 16 .

[0023] Reference Figure 2 and Figure 3The upper and lower ends of the inner wall of the fixed frame 7 are penetrated with sliding grooves 11, and the upper and lower ends of the movable block 9 pass through the sliding grooves 11 and are welded with fixed protrusions 12 on the outside. The sliding grooves 11 and the fixed protrusions 12 are interlocked with each other. By making the movable block 9 move along the fixed frame 7, the movable block 9 drives the fixed protrusions 12 to move along the inside of the sliding grooves 11, keeping the movable block 9 in a stable active state inside the fixed frame 7, which reflects the active support effect of the fixed protrusions 12 on the movable block 9.

[0024] The implementation principle of a label detection and positioning device in an embodiment of the present application is as follows: by placing the product on the upper surface of the conveyor belt 2 for conveying, the product is moved close to the label detector 3 for label detection, the limit screw 15 is rotated to push the rack plate 16 to move along the outer surface of the gear 13, so that the gear 13 drives the movable frame 5 to rotate along the inside of the fixed frame 4, and then the two movable frames 5 are rotated to adjust the spacing, so that the movable frame 5 is suitable for products of different sizes, and the product near the edge of the conveyor belt 2 is guided and centered by the guide roller 6, so that the product can be conveyed along the middle position of the upper surface of the conveyor belt 2. When the product is conveyed close to the fixed frame 7, the cylinder 8 is started to push the movable block 9 along the inside of the fixed frame 7. The input end of the power supply of the cylinder 8 is electrically connected to the output end of the external power supply, and the fixed protrusion 12 is moved along the sliding groove 11 to keep the movable block 9 in a stable movable state inside the fixed frame 7, so that the movable block 9 pushes the baffle plate 10 to slide out along the inside of the fixed frame 7 to block the product, and then guide the product, so that the label can be flush with the detection end of the label detector 3, so that the label detector 3 can detect the label on the product being transported; compared with the prior art, this solution has the effect of facilitating the positioning and guiding of the products transported on the conveyor belt 2, improves the overall placement effect of the product near the label detector 3, and solves the problem of the position offset of the product during transportation affecting the label detection.
