Embodiment Construction

[0037] The word "embodiment" as used in this specification means serving as an example, instance or illustration. Furthermore, the article "a" as used in this specification and the appended claims may generally be construed to mean "one or more" unless specified otherwise or clear from context to refer to a singular form.

[0038] In the present invention, by setting the two edges of the same plane of the box as oblique surfaces, the infrared signals will not be blocked because they are oblique surfaces, and a light transmitter is used to emit infrared signals from one end of the edge to the other end, so the light at the other end The receiver can receive the infrared signal to determine whether the box is placed in the correct direction. If the box is placed incorrectly, the infrared signal will be blocked by the right or round corners of the box, so that the light receiver cannot receive the infrared signal, so as to determine the box Wrong orientation delivery. Therefore,...

Abstract

The invention discloses a box direction recognition method. The method comprises the steps that a light emitter emits infrared signals to a light receiver; the light receiver generates corresponding signals by judging whether the infrared signals are received or not; the signals generated by the light receiver are judged; when it is judged that the signals generated by the light receiver are open signals, it is determined that boxes are placed correctly; when it is judged that the signals generated by the light receiver are closing signals, it is judged that boxes are placed mistakenly, and alarm signals are generated. According to the box direction recognition method, the phenomenon that boxes are placed reversely can be effectively prevented, and the problem that boxes are lost when placed reversely is effectively solved.

Description

【Technical field】 [0001] The invention relates to the technical field of identification, in particular to a method and system for identifying the direction of a box. 【Background technique】 [0002] EPPBox (ExpandedPolypropyleneBox, expanded polypropylene box) is used for glass packaging, storage, and transportation. Due to the advantages of recyclability and high pressure resistance, foamed polypropylene boxes are currently widely used in the liquid crystal industry. When using the expanded polypropylene box to store the LCD panel, in order to ensure the stability of the process, the post-process or the convenience of the customer, it is necessary to ensure the consistency of the direction of the LCD panel in the expanded polypropylene box, and the Consistency of box orientation. Therefore, there is an arrow mark on the foamed polypropylene box, and it is up to personnel to identify the direction when refilling. There is a certain probability of reverse throwing, resulting...
