Embodiment Construction

[0040] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0041] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "inner", "outer", "left", "right" and similar expressions are used herein for the purpose of descripti...

Abstract

The present invention relates to a detection method and device for coding position deviation, comprising: setting more than one marker on one side of the prefabricated coding position of a prefabricated part; adjusting the coding position to be consistent with the corresponding prefabricated coding position; Spray the marking material; the detection device analyzes the reflection of the marking material, and an alarm will be issued if there is any deviation; adjust the coding direction of the inkjet jet according to the deviation. The beneficial effect is that: the marker on the side of the preform coding position has a photosensitive function, and the detection part of the detection device detects the photosensitive marker, because the marker is a conical or conical protrusion, then the detection part can be based on The color change of the photosensitive part on the protrusion can identify the direction of deviation, and then fine-tune the position of the nozzle; because the detection is due to the change of photosensitive brightness, the raised structure makes the difference of photosensitive brightness more obvious and more suitable identified by staff.

Description

technical field [0001] The invention relates to the technical field of coding detection, in particular to a detection method and device for coding position deviation. Background technique [0002] "Coding" is a verb rather than a noun. It specifically refers to the process of printing information codes by inkjet printers, such as printing production dates, barcodes, QR codes, and serial codes on product packaging, all of which can be called inkjet codes. . Coding is very common now, which is equivalent to the "walking label" of the product, representing the unique characteristics of the product. [0003] Coding can be done on a flat surface, similar to paper, printing bags, etc., and also on curved surfaces, similar to the production date of beverage cans. The quality of the traditional inkjet printer's coding effect is related to many factors. , similar to the temperature and humidity of the environment, the quality of inkjet, the drying speed of ink, etc.; Among them, fo...
