[0002] With the development of information technology, it provides a reliable management means for modern manufacturing industry. Especially in the industry of earphones, data lines and the like, the whole production process of products is automatically identified, recorded and controlled through label bar codes, so as to realize transparent management, prevent, discover and timely correct errors in production, and trace and clearly query the production process of products to analyze the causes of defective products. Therefore, in the automatic production packaging equipment, a label with a bar code needs to be pasted on the required position of a product, so as to facilitate scanning and controlling in each production link. When the production of the product is completed and the product is qualified, the label needs to be torn off, and then the product is packaged and delivered. A stable and reliable label tearing device is necessary.

[0003] The traditional working mode is to manually tear off the bar code label of each product, which is tedious, labor-intensive and low in working efficiency. The existing label tearing mechanism uses single-sided adhesive tape, which is driven by a cylinder to press the adhesive tape on the product, and the small label on the product is adhered away by controlling the torsion of a servo electrode and the angle turned. However, the radius of the adhesive tape roll changes from large to small during use, which causes the length of the adhesive tape to be inconsistent when turned through the same angle, resulting in a large amount of waste of the adhesive tape and incomplete tearing of the label.

The adhesive tape conveying mechanism 400 is used for conveying the adhesive tape to the label tearing mechanism 300 and conveying the adhesive tape back to the adhesive tape conveying mechanism 400 for recycling after the label tearing is completed. A plurality of guide wheels and auxiliary wheels can be arranged according to actual work requirements, so as to ensure that the adhesive tape is taut and the conveying is stable and uniform without sliding. The label tearing mechanism 300 comprises the base plate 310 and the moving piece 320. The base plate 310 is slidingly connected with the rack 100, and the moving piece 320 is slidingly connected with the base plate 310. The sliding connection directions of the base plate 310 and the moving piece 320 are perpendicular to each other in the vertical plane, so as to ensure that the moving piece 320 can move in the vertical plane at will. In addition, the moving piece 320 is wound with adhesive tape for tearing the label on the workpiece.

[0032] The specific working principle is that the positioning mechanism 200 moves towards the workpiece and compact and positions the workpiece.
