Labeling head and control method of labeling device

Abstract

The invention relates to a labeling head, which comprises a body, at least one row of negative pressure through holes and at least one row of positive pressure through holes, wherein the body comprises an air pipe inserting surface and a labeling surface, and the at least one row of negative pressure through holes and the at least one row of positive pressure through holes penetrate through the air pipe inserting surface and the labeling surface of the body and are arranged along a long axis direction of the body; the two ends of the at least one row of negative pressure through holes and the two ends of the at least one row of positive pressure through holes are respectively arranged on the short sides close to the body, so that an effective suction attaching area of the labeling surface is distributed between the two long sides and the two short sides; therefore, the labeling head provided by the invention is used for stably labeling different elements of different products, and the unit productivity (UPH) is improved.

Description

technical field [0001] The invention relates to a labeling device, in particular to a labeling head of the labeling device. Background technique [0002] In the product manufacturing process, especially when the product is to be labeled, it is easy to customize different labeling heads due to the different positions of the components on the product. [0003] Such as Figure 7A In the shown labeling head 80, the vacuum hole 81 for absorbing labels is located in the middle of its labeling surface 801, which can be used for labeling a product in which a component is located in the middle of the product; another example Figure 7B Shown is another labeling head 80', its vacuum hole 81 is close to one of the short sides of its labeling surface 801, and it is aimed at the labeling operation where the components are located in the end area of ​​the product. [0004] Furthermore, when labeling products with multiple different component positions, it is also necessary to customize t...

Problems solved by technology

[0004] Furthermore, when labeling products with multiple different component positions, it is also necessary to customize the labeling heads corresponding to the vacuum holes of different component positions; therefore, if there are many types of products, the labeling device must be equipped with more Labeling head, in order to replace the appropriate labeling head for labeling operations, not only increases the cost of labeling, but also increases the complexity of labeling operations, time-consuming and labor-intensive

[0005] Also, see further Figure 7B , because the vacuum hole 81 of the existing labeling head is also used as a positive pressure hole, it is difficult to control the labeling stability of vacuum adsorption labels and positive pressure airflow (Clean Dry Air, hereinafter referred to as CDA), and it is easy to cause the product to be at the height of the component. Inconsistency, the problem that it cannot be effectively attached when the position is different, and the labeling stability is not good, which increases the probability of equipment abnormality, increases the product rework rate, and decreases the unit production capacity (UPH)

[0006] It can be seen from the above description that the current labeling device must replace different labeling heads for different products and components on it for labeling operations, and it is necessary to further improve it.
