Description

Technical Field

[0001] This utility model relates to the field of label inspection technology, and in particular to a label inspection machine that can automatically correct errors and replenish materials. Background Technology

[0002] A label is a keyword or brief sign used to identify a product's target, category, or content. It helps people find and locate specific targets. However, after production, some labels may have quality problems, such as typos or blurriness, which can affect the label's display effect. Therefore, it is particularly important to inspect the production quality of labels.

[0003] Most existing label inspection methods utilize label inspection machines, which are devices based on computer vision technology. Through image processing and pattern recognition, they automatically identify elements such as patterns, text, and barcodes on labels, determining whether these elements conform to established standards and specifications, thus enabling label quality inspection. However, label inspection machines lack a proper sorting mechanism when inspecting labels, especially those that fail to meet quality standards. Substandard labels must be manually removed, which is cumbersome and inconvenient, impacting the machine's efficiency. Utility Model Content

[0004] The main purpose of this invention is to provide a label inspection machine that can automatically correct errors and replenish materials, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A label inspection machine with automatic error correction and replenishment includes a first seat and a second seat. A screening device is fixedly installed at the middle of the right end of the first seat. A first servo motor is fixedly installed at the front of the right end of the first seat. A controller is fixedly installed at the rear of the right end of the first seat. A detection device is fixedly installed at the middle of the upper end of the second seat. A conveyor belt is installed between the first and second seats. A feeding platform is fixedly installed at the front ends of the first and second seats. A second servo motor is fixedly installed on the upper left side of the feeding platform. A feeding roller is fixedly installed at the output end of the second servo motor. A first receiving box is installed at the rear ends of the first and second seats.

[0007] Preferably, the screening device includes a support frame, on the upper end of which a second receiving box is placed. An electric telescopic rod is fixedly installed on the upper right end of the support frame, and a negative pressure suction cup is fixedly installed at the output end of the electric telescopic rod. A connector is installed on the upper end of the negative pressure suction cup, and there is a gap between the negative pressure suction cup and the conveyor belt. The support frame is fixedly installed in the middle of the right end of the first seat. The negative pressure suction cup is pushed to the tag on the conveyor belt by the electric telescopic rod. Since the negative pressure suction cup is connected to an external vacuum pump through the connector, when the vacuum pump is started, the negative pressure suction cup generates suction, thereby sucking up the substandard tags and retrieving them through the electric telescopic rod so that the tags can fall into the second receiving box for collection.

[0008] Preferably, the inspection device includes a mounting frame, an LED light mounted on the front right end of the mounting frame, a connecting seat fixedly mounted on the upper right end of the mounting frame, a vision inspection camera fixedly mounted on the right end of the connecting seat, and the mounting frame fixedly mounted on the middle upper end of the second base. The vision inspection camera is a SICK RulerX 70 series 3D vision inspection industrial camera, and the LED light on the mounting frame provides auxiliary illumination for the inspected tag, thereby improving the scanning effect of the device.

[0009] Preferably, a second roller and a first roller are respectively installed at the front right end and the rear right end of the conveyor belt. The output end of the first servo motor is fixedly connected to the second roller. The second roller and the first roller are rotatably mounted between the first seat and the second seat. Limit frames are fixedly installed on the upper part of one corresponding end of the first seat and the second seat, and there is a gap between the two limit frames and the conveyor belt. The first servo motor drives the second roller, which in turn drives the conveyor belt. The conveyor belt then moves the tags on it to the vision inspection camera for scanning and inspection. Moreover, the design of the limit frames on the first and second seats can limit the tags on the conveyor belt, preventing large deviations during transport.

[0010] Preferably, the lower end face of the feeding roller is in contact with the feeding platform, and the feeding roller is hollow inside and made of rubber.

[0011] Preferably, the controller is electrically connected to the first servo motor, the second servo motor, the electric telescopic rod, the LED light, and the visual inspection camera.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. First, place the label to be inspected, such as a hang tag, at the lower end of the feeding roller. The feeding roller is driven by servo motor number two, which then pushes the hang tag onto the conveyor belt. At this time, servo motor number one drives roller number two, which in turn drives the conveyor belt. The conveyor belt then moves the hang tag on it to the vision inspection camera on the inspection device for scanning. The LED lights on the fixed frame provide auxiliary lighting for the inspected hang tags, thereby improving the scanning effect of the device. When the vision inspection camera detects that the hang tag information is blurry or incorrect, the negative pressure suction cup is pushed to the hang tag on the conveyor belt by the electric telescopic rod on the screening device. Since the negative pressure suction cup is connected to an external vacuum pump through a connector, when the vacuum pump is started, the negative pressure suction cup generates suction, thereby picking up the substandard hang tag and retrieving it through the electric telescopic rod, so that the hang tag can fall into the receiving box number two for collection, thereby improving the processing efficiency of the device.

[0014] 2. The design of the limit frame on the No. 1 and No. 2 seats can limit the tags on the conveyor belt and prevent the tags from shifting too much during transportation. Attached Figure Description

[0023] like Figure 1-4 As shown, a label inspection machine with automatic error correction and replenishment includes a first seat 1 and a second seat 4. A screening device 2 is fixedly installed in the middle of the right end of the first seat 1. A first servo motor 5 is fixedly installed in the front of the right end of the first seat 1. A controller 11 is fixedly installed in the rear of the right end of the first seat 1. A detection device 3 is fixedly installed in the middle of the upper end of the second seat 4. A conveyor belt 6 is installed between the first seat 1 and the second seat 4. A feeding platform 8 is fixedly installed at the front end of the first seat 1 and the second seat 4. A second servo motor 9 is fixedly installed in the upper left part of the feeding platform 8. A feeding roller 10 is fixedly installed at the output end of the second servo motor 9. A first receiving box 7 is installed in the rear end of the first seat 1 and the second seat 4. The lower end face of the feeding roller 10 is in contact with the feeding platform 8, and the feeding roller 10 is hollow inside and made of rubber.

[0024] The screening device 2 includes a support frame 20, with a second receiving box 24 placed on the upper end of the support frame 20. An electric telescopic rod 21 is fixedly installed on the upper right end of the support frame 20, and a negative pressure suction cup 22 is fixedly installed at the output end of the electric telescopic rod 21. A connector 23 is installed on the upper end of the negative pressure suction cup 22, and there is a gap between the negative pressure suction cup 22 and the conveyor belt 6. The support frame 20 is fixedly installed in the middle of the right end of the first seat 1. The negative pressure suction cup 22 is pushed to the tag on the conveyor belt 6 by the electric telescopic rod 21. Since the negative pressure suction cup 22 is connected to an external vacuum pump through the connector 23, when the vacuum pump is started, the negative pressure suction cup 22 generates suction, thereby sucking up the substandard tags and retrieving them through the electric telescopic rod 21, so that the tags can fall into the second receiving box 24 for collection.

[0025] The inspection device 3 includes a mounting frame 30. An LED light 32 is mounted on the front right end of the mounting frame 30. A connecting seat 31 is fixedly mounted on the upper right end of the mounting frame 30. A vision inspection camera 33 is fixedly mounted on the right end of the connecting seat 31. The mounting frame 30 is fixedly mounted on the upper middle part of the second seat 4. The vision inspection camera 33 is a SICK RulerX 70 series 3D vision inspection industrial camera. The LED light 32 on the mounting frame 30 provides auxiliary illumination for the inspected tags, thereby improving the scanning effect of the device.

[0026] A second roller 41 and a first roller 40 are respectively installed at the front right end and rear right end of the conveyor belt 6. The output end of the first servo motor 5 is fixedly connected to the second roller 41. The second roller 41 and the first roller 40 are rotatably mounted between the first seat 1 and the second seat 4. Limiting frames 42 are fixedly installed on the upper part of one corresponding end of the first seat 1 and the second seat 4, and there is a gap between the two limiting frames 42 and the conveyor belt 6. The controller 11 is electrically connected to the first servo motor 5, the second servo motor 9, the electric telescopic rod 21, the LED light 32, and the vision inspection camera 33. The first servo motor 5 drives the second roller 41, which in turn drives the conveyor belt 6. The conveyor belt 6 then moves the tags on it to the vision inspection camera 33 for scanning and inspection. Moreover, the design of the limiting frames 42 on the first seat 1 and the second seat 4 can limit the tags on the conveyor belt 6, preventing large deviations during transport.

[0027] It should be noted that this utility model is a label inspection machine with automatic error correction and replenishment capabilities. First, the controller 11 is connected to an external power source. Then, the label to be inspected, such as a hang tag, is placed at the lower end of the feeding roller 10. The feeding roller 10 is driven by the second servo motor 9, which in turn pushes the hang tag onto the conveyor belt 6. At this point, the second roller 41 is driven by the first servo motor 5, which in turn drives the conveyor belt 6. The conveyor belt 6 then moves the hang tag on it to the visual inspection camera 33 on the inspection device 3 for scanning and inspection. Simultaneously, the design of the limiting brackets 42 on the first and second seats 1 and 4 can limit the hang tag on the conveyor belt 6, preventing... The tagless system experiences significant deviation during transport, and the LED lights 32 on the mounting bracket 30 provide auxiliary illumination for the detected tags, thereby improving the scanning effect of the device. When the visual inspection camera 33 detects blurry or incorrect tag information, the electric telescopic rod 21 on the screening device 2 pushes the negative pressure suction cup 22 to the tag on the conveyor belt 6. Since the negative pressure suction cup 22 is connected to an external vacuum pump through the connector 23, when the vacuum pump is started, the negative pressure suction cup 22 generates suction, thereby picking up the substandard tags and retrieving them through the electric telescopic rod 21, allowing the tags to fall into the second receiving box 24 for collection, thus improving the processing efficiency of the device.
