Description

Technical Field

[0001] This utility model relates to the field of labeling technology, and in particular to an automatic labeling device for die-cut products. Background Technology

[0002] Traditional manual labeling methods are inefficient and inaccurate, making it difficult to meet the requirements of large-scale production. As a result, automatic labeling devices were developed, which greatly improve labeling efficiency and quality and effectively reduce labor costs.

[0003] Current linear die-cutting automatic labeling devices on the market first peel the label from the backing paper and then apply external force to complete the attachment. However, in order to achieve accurate label positioning and tight adhesion, a sliding force must be applied to the label. This causes serious damage to the fragile label structure. The label is usually composed of a top printed layer, an intermediate adhesive layer, and a bottom release paper. The sliding force can easily scratch the printed layer, which not only damages the label's appearance but also makes it difficult to accurately identify or read key information such as product model, production date, and QR code, affecting product sales and traceability management. In addition, the sliding force can also cause local damage to the label's adhesive layer, reducing the adhesion between the label and the product surface, resulting in problems such as poor adhesion and easy detachment. Utility Model Content

[0004] In order to overcome the problem that existing automatic labeling devices for linear die-cut products require applying sliding force to the label during labeling, and that the label itself is fragile and therefore easily scratched and damaged during labeling, this utility model provides an automatic labeling device for die-cut products.

[0005] The technical solution is as follows: An automatic labeling device for die-cut products includes a labeling processing chamber, a belt conveyor, a three-axis labeling component, a vision positioning and recognition component, and a label feeding component; the belt conveyor is installed at the upper end of the processing table of the labeling processing chamber; the three-axis labeling component is installed behind the belt conveyor; the label feeding component is installed behind the three-axis labeling component; the vision positioning and recognition component is installed above the belt conveyor; the three-axis labeling component includes a lead screw guide rail three-axis adjustment platform, a vacuum pump, and a multi-hole hollow suction plate.

[0006] Furthermore, a three-axis adjustment platform with a lead screw guide is installed at the rear of the belt conveyor; a vacuum pump is fixedly installed inside the output end of the three-axis adjustment platform with a lead screw guide; a multi-hole hollow suction plate is installed at the lower end of the vacuum pump, and the output end of the vacuum pump is connected to the interior of the multi-hole hollow suction plate; a uniform and dense vacuum suction plate is installed on the lower end face of the multi-hole hollow suction plate.

[0007] Furthermore, a label plate is installed at the rear of the three-axis adjustment platform of the lead screw guide, and the label plate is fixedly connected to the processing table of the labeling processing chamber; both the upper and lower ends of the label plate are provided with grooves for the label tape to be wound.

[0008] Furthermore, a guide wheel is provided at the rear of the label plate, and the guide wheel is rotatably connected to the processing table of the labeling processing chamber; a label tape roller and a waste recycling roller are respectively provided at the upper and lower ends of the rear of the guide wheel, and the waste recycling roller is driven to rotate by an external servo motor. The label tape on the label tape roller passes through the guide wheel and wraps around the label plate, and then is guided by the guide wheel to the waste tape of the last label tape to be wound and connected to the waste recycling roller.

[0009] Furthermore, the upper surface of the label strip wrapped around the label plate is the non-adhesive surface of the label.

[0010] Furthermore, the visual positioning and recognition component includes a vertical adjustment lead screw rail and a visual recognition camera; the label feeding component includes a label plate, guide wheels, waste recycling rollers, and label belt rollers; a vertical adjustment lead screw rail is installed above the belt conveyor, and the housing of the vertical adjustment lead screw rail is fixedly connected to the inner wall of the labeling processing chamber.

[0011] Furthermore, a visual recognition camera is fixedly installed at the front end of the vertical adjustment screw rail output end, and the lens of the visual recognition camera is positioned to capture images of the belt conveyor.

[0012] The beneficial effects are as follows: This utility model uses the visual recognition camera of the visual positioning and recognition component to identify the die-cut products placed on the belt conveyor, thereby realizing the coordinate positioning and recognition function of the die-cut products. The coordinate data of this recognition is used to assist the three-axis adjustment platform of the lead screw guide rail in dynamically adjusting the position of the vacuum pump and the porous hollow suction plate. The three-axis adjustment platform of the lead screw guide rail first moves the porous hollow suction plate to the label plate. Then, the vacuum pump extracts the air below the porous hollow suction plate and uses the vacuum suction to pick up the label tape wrapped on the label plate. Then, the porous hollow suction plate containing the label is placed on the upper surface of the die-cut product and pressed down. At this time, the lower surface of the label is stuck to the die-cut product due to the adhesive effect of the adhesive. Then, the vacuum pump stops suction, releases the label and resets to complete the labeling process. Due to the precise positioning and vacuum adsorption labeling method of the three-axis labeling component, combined with the continuous feeding of the label feeding component, the label can be applied without scratches, effectively improving the integrity of the labeling and improving the labeling quality.

[0013] By setting up the visual positioning and recognition component, the visual recognition camera of the component is used to identify the die-cut products transported above the belt conveyor in real time, and provide images to analyze the coordinates of the products, thereby dynamically adjusting the three-axis labeling component and realizing the precise labeling function, effectively improving the labeling positioning accuracy, eliminating the need for strict product positioning, and improving production efficiency.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

The label feeding assembly 5 is installed behind the three-axis labeling assembly 3. The vision positioning and recognition assembly 4 is installed above the belt conveyor 2. The three-axis labeling assembly 3 includes a lead screw guide rail three-axis adjustment platform 301, a vacuum pump 302, and a porous hollow suction plate 303.

[0024] A label plate 501 is provided behind the lead screw guide three-axis adjustment platform 301, and the label plate 501 is fixedly connected to the processing table of the labeling processing chamber 1; both the upper and lower ends of the label plate 501 are provided with grooves for the label tape to be wound.

[0025] A guide wheel 502 is provided behind the label plate 501, and the guide wheel 502 is rotatably connected to the processing table of the labeling processing chamber 1. A label tape roller 504 and a waste recycling roller 503 are respectively provided at the upper and lower ends behind the guide wheel 502. The waste recycling roller 503 is driven to rotate by an external servo motor. The label tape on the label tape roller 504 passes through the guide wheel 502 and wraps around the label plate 501. Then, the waste tape of the last label tape is guided by the guide wheel 502 and wound around the waste recycling roller 503.

[0026] The upper surface of the label tape wrapped around the label plate 501 is the non-adhesive surface of the label.

[0027] The visual recognition camera 402 of the visual positioning and recognition component 4 identifies the die-cut products placed on the belt conveyor 2, thereby realizing the coordinate positioning and recognition function of the die-cut products. The coordinate data identified is used to assist the three-axis adjustment platform 301 of the lead screw guide rail in dynamically adjusting the position of the vacuum pump 302 and the porous hollow suction plate 303. The three-axis adjustment platform 301 of the lead screw guide rail first moves the porous hollow suction plate 303 onto the label plate 501. Then, the vacuum pump 302 extracts the air below the porous hollow suction plate 303 and uses the vacuum suction to lift the label plate. The label is picked up by the label tape wound on the 501. Then, the porous hollow suction plate 303 containing the label is placed on the upper surface of the die-cut product and pressed down. At this time, the lower surface of the label is stuck to the die-cut product due to the adhesive. Then, the vacuum pump 302 stops suction, releases the label and resets to complete the labeling process. Due to the precise positioning and vacuum suction of the three-axis labeling component 3, combined with the continuous feeding of the label feeding component 5, the label can be applied without scratches, effectively improving the integrity of the label and the quality of the labeling.
