Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, and particularly relates to a label precise peeling mechanism. Background Art

[0002] Automatic labeling machines are increasingly used in production lines. In order to label a series of information such as production standards, production dates, production parameters, and manufacturers on the outer surface of products, and even labels that need to be changed every day, automatic labeling machines are the best choice. In order to deal with labels of various complex structures, it is necessary to design automatic labeling equipment of different specifications and models. Especially for the labeling of extremely small labels, especially the important touch buttons of electronic products, usually diaphragms are pasted on these local features, and the diaphragms are also neatly pasted on the base paper. The rolled base paper also needs to be automatically labeled by an automatic labeling machine. However, in the step feeding of micro-miniature diaphragms, it is necessary to precisely control the lateral displacement and longitudinal displacement of the diaphragm feeding. Otherwise, it is very difficult to precisely control the relatively small-sized diaphragm to be picked up after peeling the diaphragm. Therefore, it is necessary for us to design a stable and precise peeling mechanism for the rolled strip of small-sized labeling materials. Summary of the Utility Model

[0003] The purpose of the utility model is: in order to be able to precisely control the lateral displacement and longitudinal displacement of the diaphragm feeding, so that after peeling the diaphragm, the relatively small-sized diaphragm to be picked up can be precisely controlled. We design and provide a label precise peeling mechanism, which through multiple lateral limitings, and pressing and flattening the base paper with small labels or film materials pasted on it, achieves stable feeding of the strip in the lateral and longitudinal directions, and precisely controls the relatively small-sized diaphragm to be picked up.

[0004] The technical solutions adopted to solve the above problems are as follows:

[0005] A label precise peeling mechanism includes a flat feeding table, a peeling table, a lifting table, as well as multiple groups of limiting components for limiting the lateral position of the base paper and a flattening component for pressing on the upper surface of the base paper.

[0006] The front end of the feeding table is flush-connected with the peeling table. Multiple longitudinally arranged limiting grooves are provided on the feeding table, and limiting components are arranged in the limiting grooves.

[0007] The limiting component includes a sliding rod, a limiting sliding block and a locking screw. The limiting sliding block is longitudinally sleeved on the sliding rod and includes two left and right limiting sliding blocks. A locking hole radially facing the sliding rod is opened on the limiting sliding block. The limiting sliding block is locked by the cooperation of the locking screw and the locking hole. The base paper of the diaphragm to be peeled is clamped between the two limiting sliding blocks to limit the lateral displacement and stably feed the material.

[0008] The paving component includes bearing seats, rotating shafts, pressing pieces, and positioning screws arranged on both sides of the base paper. The rotating shaft is longitudinally arranged above the base paper and is fitted with the bearing seats on both sides. The pressing pieces are connected to the rotating shaft through the positioning screws. A pressing plate is arranged at the front end of the pressing piece. A passing groove is provided in the pressing plate opposite to the position of the film to be circulated on the base paper.

[0009] A stripping edge in a triangular shape is provided at the front end of the stripping table. The base paper is tightened by bypassing the stripping edge and pulled downward for winding, and the film is stripped from the base paper to the lifting table at the front end for connection.

[0010] An anti-sticking plate for receiving the stripped film is arranged on the lifting table to ensure that the lower surface of the stripped film does not adhere to the lifting table.

[0011] Further, a slider rail assembly is arranged below the lifting table, and the lateral displacement distance of the lifting table is adjusted by a locking bolt.

[0012] Further, a plurality of position sensors facing the stripped film are arranged below the gap between the lifting table and the stripping table to detect the quantity and position of the stripped film, so as to facilitate the picking action of the automation equipment in the subsequent process.

[0013] Further, a guiding roller is arranged below the stripping table to facilitate the winding of the waste base paper.

[0014] Further, the pressing piece forms a lever with the rotating shaft as the fulcrum. A pressing plate is arranged at the front end of the lever, and a pushing spring and an adjusting screw are arranged at the rear end of the lever. The pushing spring applies a pushing force to the pressing piece to increase the pressing force of the pressing plate on the base paper and improve the positioning accuracy of the base paper.

[0015] The beneficial effects of the present utility model are as follows:

[0016] Through multiple groups of limiting components for limiting the lateral position of the base paper and the paving component pressing on the upper surface of the base paper, the label precise stripping mechanism achieves stable feeding of the material belt in the horizontal and vertical directions, accurately controls the small-sized film to be picked up to be smoothly positioned on the anti-sticking plate, which is practical and convenient.

The base paper 20 is wound around the stripping blade 18 and tightened, and then pulled downward and wound up, so as to strip the diaphragm 14 from the base paper 20 to the lifting table 12 connected at the front end. A guiding roller is arranged below the stripping table 10, including a first guiding roller 25 and a second guiding roller 26, so as to facilitate the winding of the waste material of the base paper 20.

[0029] An anti-sticking plate 13 for receiving the stripped diaphragm 14 is arranged on the lifting table 12 to ensure that the lower surface of the stripped diaphragm 14 does not adhere to the lifting table 12.

[0030] Refer to Figure 5 , a slider 11 sliding rail assembly is arranged below the lifting table 12, and the lateral displacement distance of the lifting table 12 is adjusted by a locking bolt.
