[ detailed description ] embodiments

Embodiment 1, the high-speed laser code-engraving system of this embodiment, as shown in fig. 1, includes: the laser code engraving machine 11, and an electric eye 12 and a general control unit 13 which are respectively connected with the laser code engraving machine 11.

And the master control unit 13 is used for sending the tracing code data set to the laser code carving machine 11 and complementing the tracing code data set after part of the tracing codes are used. Specifically, initially, the total control unit 13 sends the tracing code data sets D1, D2, D3, D4, D5 … D98, D99, and D100, and the 100 tracing codes are sent to the laser code scanner 11, and the laser code scanner 11 stores the received tracing codes for use in preparation of the tracing codes, and simultaneously, the total control unit 13 internally opens a thread to poll and access the laser code scanner 11 at a frequency of 100ms, so as to obtain the number of the tracing codes stored in the laser code scanner 11. When the total control unit 13 inquires that the number of the tracing codes stored in the laser code carving machine 11 is smaller than the preset threshold, taking 31 thresholds as an example in this embodiment, 70 tracing codes are continuously sent to the laser code carving machine 11, and a monitoring and tracing code sending period is completed.

And the electric eye 12 is used for controlling the laser code etching machine 11 to etch the tracing code for the object when the object is detected to pass through.

The laser decoding machine 11 is configured to store the trace back code data set sent by the overall control unit 13, etch the first trace back code D1 in the trace back code data set on the object, and remove the trace back code D1 after the etching is completed. At this time, the first trace-back code is D2, and the next time the laser lithography code machine 11 performs etching, the first trace-back code is D2. The laser code etching machine 11 finishes etching with the first tracing code every time, removes the first tracing code after etching is finished, continues etching the next object, and performs the steps repeatedly in the way to realize automatic high-speed code etching.

Embodiment 2, the laser code-engraving machine of this embodiment, as shown in fig. 2, includes: a laser code carving machine body 21 and a buffer subunit 22.

And the buffer subunit 22 is used for storing the traceback code data set. For example, the retroactive code data sets are D1, D2, D3, D4, D5 … D98, D99 and D100, which are 100 retroactive codes.

The laser code carving machine body 21 is used for etching the first tracing code in the tracing code data set stored in the cache subunit 22 on an object, and removing the tracing code after the etching is finished. Specifically, the first tracing code D1 in the tracing code data set is etched on the object, and after the etching is completed, the tracing code D1 is removed. At this time, the first tracing code is changed into D2, and when the laser code carving machine body 21 is etched next time, the first tracing code is changed into D2. The laser code carving machine body 21 finishes etching with the first tracing code every time, removes the first tracing code after the etching is finished, continues to etch the next object, and performs the steps in a reciprocating manner to realize automatic high-speed code carving.

Embodiment 3, the method for high-speed laser coding of this embodiment, as shown in fig. 3, includes the following main steps:

s31, initialization: and the master control unit sends a tracing code data set to the laser code carving machine. Specifically, at the beginning, the total control unit sends the tracing code data sets D1, D2, D3, D4, D5 … D98, D99 and D100, and the 100 tracing codes are sent to the laser code printer, and the laser code printer stores the received tracing codes for use as the tracing codes.

S32, high-speed laser code engraving: when the electric eye detects that an object passes through, the laser code etching machine is controlled to etch the tracing code on the object, the laser code etching machine etches the first tracing code in the internally stored tracing code data set on the current object, and the tracing code is removed after etching is completed. Specifically, the laser lithography code machine etches the first tracing code D1 in the tracing code data set on the object, and after the etching is completed, removes the tracing code D1. At this time, the first traceback code is changed into D2, and when the laser lithography code machine is etched next time, the first traceback code is changed into D2. The laser code etching machine finishes etching with the first tracing code every time, removes the first tracing code after the etching is finished, continues etching the next object, and performs the steps repeatedly in the way to realize automatic high-speed code etching.

S33, complementing the tracing code data set: after part of the tracing codes are used, the total control unit complements a tracing code data set to the laser code engraving machine. Specifically, the step S31 may be performed simultaneously, and the master control unit starts a thread inside, and polls and accesses the laser code scanner at a frequency of 100ms to obtain the number of the trace back codes stored in the laser code scanner. When the total control unit inquires that the number of the tracing codes stored in the laser code carving machine is smaller than a preset threshold, taking 31 thresholds as an example in the embodiment, 70 tracing codes are continuously sent to the laser code carving machine, and a monitoring and tracing code sending period is completed.
