Problems solved by technology

[0010] Since the detection method of the position offset of the coding of the die-casting parts in the prior art requires the use of precision measuring equipment such as a projector, the detection cost is relatively high. In addition, the detection method cannot be detected in real time on the production line, and the detection process also requires workers with special operating skills. It is not only labor-intensive, but also the detection efficiency is low

Embodiment 1

[0045] see image 3 , Figure 4 and Figure 5 , in this embodiment, in the step 201 to step 205, the coding outline structure of the die casting 20 is a raised frame structure 21, and there is a containing plane inside the raised frame structure 21, its shape and size The outline of the preset coding content is adapted to accommodate the coding content, and the coding content 22 is spray-printed on the receiving plane surrounded by the raised frame structure 21 . When the coding position deviates, the coding content 22 exceeds the accommodation range of the containing plane and intersects with the inner edge of the raised frame structure 21 .

Embodiment 2

[0047] see image 3 , Figure 6 and Figure 7 , in this embodiment, in the step 201 to step 205, the coding profile structure of the die casting 30 is a boss structure 31, the upper surface of the boss structure 31 is a receiving plane, and its shape and size are the same as the preset spraying The outline of the code content is adapted to accommodate the inkjet content 32 , and the inkjet content 32 is printed on the containing plane on the upper surface of the boss structure 31 . When the coding position deviates, the coding content 32 exceeds the accommodation range of the upper surface and intersects with the edge of the boss structure.

Embodiment 3

[0049] see image 3 , Figure 8 and Figure 9 , in this embodiment, in the step 201 to step 205, the coding outline structure of the die casting 40 is a concave frame structure 41, and there is a containing plane inside the concave frame structure 41, its shape and size The outline of the preset inkjet content is adapted to accommodate the inkjet content 42 , and the inkjet content is inkjet printed on the receiving plane surrounded by the concave frame structure 41 . When the coding position deviates, the coding content 42 exceeds the accommodating range of the containing plane and intersects with the inner edge of the concave frame structure 41 .

Abstract

The present invention provides a method for detecting the deviation of the coding position on the die-casting, which is characterized in that it mainly includes the following steps: die-casting a coding contour structure at the preset coding position of the die-casting to accommodate the preset coding; Adjust the position of the inkjet printer; position the molded die-casting part in the printing direction of the inkjet printer; spray code on the die-casting part; visually check whether the actual inkjet code on the die-casting part exceeds the accommodation range of the inkjet outline structure. Compared with the prior art, the method for detecting the deviation of the coding position on the die-casting part of the present invention does not require other auxiliary measuring tools, is simple to operate, has high detection efficiency, and can detect whether the coding position on the die-casting part is shifted in real time online. The defects of the prior art are overcome, the production cost is reduced, and the production efficiency is improved. The present invention also provides a coding outline structure of the die-casting used in the above detection method.

Description

【Technical field】 [0001] The invention relates to the coding detection technology, in particular to a detection method and structure for detecting the offset of the coding position on a die casting. 【Background technique】 [0002] Coding is the process of printing characters, icons, barcodes and other content on products in a non-contact manner with an inkjet printer. In the production of metal die castings, it is often necessary to spray codes at a preset position on a certain plane of the die casting product, so as to facilitate the identification of die castings in subsequent production. If the actual coding position on the workpiece deviates from the preset position, it will affect the subsequent identification of the die casting. [0003] see figure 1 After spraying the code 12 at the preset position of the upper end surface 11 of the die-casting part 10, since there is no reference object as the relative position of the spray code 12 on the plane, it is impossible to...
