Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0022] Reference Figures 1 to 3As shown, a preferred embodiment of this application of a three-code printing line includes a production line 1, an outer code laser marking machine 2, an inner code laser marking machine 3, and a hidden code inkjet printer 4. The outer code laser marking machine 2, the inner code laser marking machine 3, and the hidden code inkjet printer 4 are arranged on one side of the production line 1 along the conveying direction of the production line 1. The outer code laser marking machine 2 is used to mark the outer wall surface of the product with a QR code, the inner code laser marking machine 3 is used to mark the inner wall surface of the product with a QR code, and the hidden code inkjet printer 4 is used to inkjet print a hidden code on the outer wall surface of the product.

[0023] In practical applications, products are placed on production line 1, which moves the products. During this movement, the products are sequentially marked by an outer code laser marking machine 2, an inner code laser marking machine 3, and an invisible code inkjet printer 4. Specifically, the outer code laser marking machine 2 marks the outer surface of the product with a QR code, the inner code laser marking machine 3 marks the inner surface of the product with a QR code, and the invisible code inkjet printer 4 inkjet prints an invisible code on the outer surface of the product. Thus, by using the three-code inkjet printing method of this application to mark the products, three types of inkjet codes are printed on the products, making it difficult for all the inkjet codes to be lost, thereby avoiding the failure of traceability due to the loss of the markings.

[0024] Furthermore, the three-code printing line also includes a barcode scanner 5 and an industrial control computer 6. Along the conveying direction of the production line 1, the barcode scanner 5 is located between the outer code laser marking machine 2 and the inner code laser marking machine. The outer code laser marking machine 2, the inner code laser marking machine 3, the invisible code inkjet printer 4, and the barcode scanner 5 are all electrically connected to the industrial control computer 6. Based on the settings of the barcode scanner 5 and the industrial control computer 6, after the outer code laser marking machine 2 marks the QR code on the outer wall of the product, the barcode scanner 5 reads the content of the QR code and transmits it to the industrial control computer 6. The industrial control computer 6 sends the data to the inner code laser marking machine 3 and the invisible code inkjet printer 4. The inner code laser marking machine 3 and the invisible code inkjet printer 4 mark the product based on the data. Based on this, the three types of printed codes on the product record the same information.

[0025] In this embodiment, the three-code printing line also includes a first mounting bracket 7. The scanner 5 is fixedly connected to the production line 1 through the first mounting bracket 7. The structure is compact and the scanner 5 is stably set.

[0026] In this embodiment, the three-code printing line also includes a second mounting bracket 8. The second mounting bracket 8 includes a first frame 81 and a first manual cross slide 82. The first frame 81 is located on one side of the production line 1, and the first manual cross slide 82 is fixedly connected to the first frame 81. The external code laser marking machine 2 is fixedly connected to the first manual cross slide 82. The first manual cross slide 82 is used to adjust the horizontal and vertical positions of the external code laser marking machine 2. Specifically, the first manual cross slide 82 includes two manual slides, one of which is vertically set and the other is horizontally set. The two manual slides are connected to each other. The external code laser marking machine 2 is fixedly connected to the horizontally set manual slide. The two manual slides can adjust the horizontal and vertical positions of the external code laser marking machine 2 so that the external code laser marking machine 2 can assign codes to the preset positions of the products.

[0027] In this embodiment, the coding line for three-code printing also includes a third mounting bracket 9. The third mounting bracket 9 includes a second frame 91 and a second manual cross slide 92. The second frame 91 is located on one side of the production line 1, and the second manual cross slide 92 is fixedly connected to the second frame 91. The inner code laser marking machine 3 is fixedly connected to the second manual cross slide 92. The second manual cross slide 92 is used to adjust the position of the inner code laser marking machine 3 in the horizontal direction and in the vertical direction. Similarly, the structure of the second manual cross slide 92 is the same as that of the first manual cross slide 82, and will not be described in detail here. The second manual cross slide 92 can adjust the position of the inner code laser marking machine 3 in the horizontal direction and in the vertical direction so that the inner code laser marking machine 3 can assign codes to the preset positions of the products.

[0028] In this embodiment, the industrial control computer 6 is fixedly connected to the second manual cross slide 92.

[0029] In this embodiment, the three-code printing line also includes a mounting platform 10 and a fourth mounting bracket 11. The invisible code inkjet printer 4 includes an inkjet printer body 41 and a printhead 42 connected to each other. The inkjet printer body 41 is placed on the mounting platform 10, and the printhead 42 is fixedly connected to the fourth mounting bracket 11, with the output end of the printhead 42 facing the side where the production line 1 is located. The inkjet printer body 41 and the printhead 42 are respectively set on the mounting platform 10 and the fourth mounting bracket 11. The advantage of this structure is that the position of the printhead 42 can be adjusted by adjusting the position of the fourth mounting bracket 11 so that the printhead 42 can assign codes to the preset position of the product without adjusting the position of the inkjet printer body 41 together. This makes the operation convenient and highly flexible.

[0030] In this embodiment, the fourth mounting bracket 11 includes a vertical pole 111, legs 112, a horizontal bar 113, a cross clamp 114, and a connecting seat 115. The vertical pole 111 is located on one side of the assembly line 1. The legs 112 are connected to the lower end of the vertical pole 111. There are multiple legs 112, which are spaced apart around the vertical pole 111. The horizontal bar 113 is connected to the vertical pole 111 through the cross clamp 114, and the length direction of the horizontal bar 113 is perpendicular to the conveying direction of the assembly line 1. The connecting seat 115 is connected to the horizontal bar. At one end of 113 along its length direction near the production line 1, the nozzle 42 is connected to the connecting seat 115. Specifically, the upright 111 and the crossbar 113 are connected by a cross clamp 114. The height of the crossbar 113 can be adjusted, and the position of the nozzle 42 in the length direction of the crossbar 113 can also be adjusted. Thus, the nozzle 42 can assign a code to the preset position of the product. In addition, the setting of the support leg 112 can ensure the stable arrangement of the upright 111. For example, the number of support legs 112 is three.

[0031] Since the positions of the outer code laser marking machine 2, the inner code laser marking machine 3, and the printhead 42 can all be adjusted, the coding lines of the three-code printing in this application can be applied to the three-code printing of products of different sizes and specifications, and have high applicability.

[0032] Furthermore, brake casters 12 are fixedly connected to the bottom of both the first frame 81 and the second frame 91, thereby facilitating the adjustment of the positions of the outer code laser marking machine 2 and the inner code laser marking machine 3.

[0033] In this embodiment, production line 1 is a belt conveyor production line 1; while production line 1, external code laser marking machine 2, internal code laser marking machine 3 and invisible code inkjet printer 4 are all existing technologies, and this application will not elaborate on them further.

[0034] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
