Description

Technical Field

[0001] The present invention belongs to the technical field of automated equipment, and particularly relates to a coding device for identifying sheet metal parts. Background Art

[0002] At present, the source of sheet metal part products is required to be traceable to ensure the quality. The way of tracing is to mark identification codes (barcodes, QR codes) on sheet metal parts and products. This identification code corresponds to the identity of the product, and in the enterprise database, relevant information such as the material source and production date of this product during all manufacturing processes is recorded using this identity. When packaging and shipping out, it is necessary to scan the identification code of the product, and query the information of the product in the database according to the scanning result. Once it is found that defective products are mixed in, they can be removed before shipping out to ensure the quality of the products shipped out. Thus, it can be seen that the importance of the identification code is extraordinary.

[0003] In the prior art, the heads of the coding devices used are mostly in a fixed form. When it is necessary to spray an identification code set obliquely, only manual labor can be relied on to perform this process, and the applicability is poor. At the same time, during manual operation, it is time-consuming and laborious for workers to identify the shape of the sheet metal parts and determine the coding position, which prolongs the production time and reduces the economic benefits.

[0063] A method for using an inkjet device for sheet metal part identification provided by the present invention:

[0064] When it is necessary to inkjet a sheet metal part, first start the first motor 38 by operating the operation console.

Since the rotation of the first driving shaft 39 drives the rotation of the Y-axis driving wheel 34, the Y-axis synchronous belt 35 is driven to move, and the purpose of Y-direction movement is achieved.

[0065] Start the second motor 43. Since the rotation of the output end of the second motor 43 drives the rotation of the output end of the first reducer 44, and then drives the rotation of the X-axis driving wheel 45. Since the rotation of the X-axis driving wheel 45 drives the movement of the X-axis synchronous belt 46, the purpose of X-direction movement is achieved.

[0066] By adopting the above technical solution, first start the third motor 54. The rotation of the output end of the third motor 54 drives the rotation of the jaw coupling 55, and then drives the movement of the slide in the lead screw kit 56, and further drives the movement of the Z-direction sliding body 57, so that the lifting connection bracket 52 moves to achieve the purpose of Z-direction movement.

[0067] According to the angle of the inkjet coding, the operation console 7 can be provided to control the driving motor 62 to adjust the angle of the nozzle 613.
