As shown in fig. 1-18, the line pipe marking machine capable of automatically identifying printing data is composed of a casing 10, a line pipe conveying assembly, a line number printing assembly, a line pipe cutting assembly and a main control circuit.
One, master control circuit
Besides the functions of controlling other functional components in the line pipe marking machine, the automatic identification and screening module and the automatic number editing module are also arranged in the line pipe marking machine.
1. Automatic identification screening module
Generally, when a wire harness (i.e., a wire) manufacturing enterprise processes a wire harness and a corresponding wire number for a customer, a lot of production data is involved, and the production data is managed inside the wire harness manufacturing enterprise and also has related data proposed by the customer.
The data related to each batch of wire harnesses comprises production date, material, batch, color, line type (dimension specification), cutting length of the wire harnesses, wire stripping mode, wire stripping length, segment type, crimping mode of the wiring terminals and the like.
The data related to the corresponding line number pipe (line number data for short), the sleeving position of the number pipe, the font type of the printed number, the font size, the character typesetting mode, the decoration type, the alignment mode, the printed content and the like.
Generally, the wire harness production enterprise compiles the production data into computer-recognizable structured data and packs the data into data packets to be transmitted between related control systems or networks in a serial or parallel mode.
The wire tube marking machine capable of automatically identifying the printing data is interconnected with the wire harness production control system in a wired or wireless mode, and an automatic identification screening module in the wire tube marking machine screens out data information (called wire number data below) related to the wire tube number in the production data and stores the data information in a memory of the main control circuit.
The automatic identification screening module is an identification model constructed by an initial learning method of human input and continuous self-learning of the module on the collected mass production data.
2. Automatic number editing module
And automatically editing the spool number according to the manually set editing rule by the wire number data stored in the main control circuit and transmitting the spool number to the main control circuit, and controlling a wire number printing component by the main control circuit to print the edited spool number on a wire number pipe corresponding to the wire harness.
3. The automatic identification screening module and the number automatic editing module realize the identification of the related production data by the following method:
1) parsing production data for structured data of a wire harness production enterprise
By analyzing the production data of the structured data, the editing rule of the production data is obtained, namely how the editing rule distinguishes each data segment with independent significance in the production data, such as a unique prompt compiled for each data segment for distinguishing the data segment with independent significance by a wire harness production enterprise, an expression mode of each data segment as a whole, what separator is adopted between two adjacent data segments for distinguishing, and a sorting rule of each data segment.
The independent meaning refers to the specific item meaning represented by the production data, namely, the production date, material, batch, color, line type (dimension specification), cutting length of wire harness, wire stripping mode, wire stripping length, segment type, crimping mode of connecting terminal, number sleeve joint position, font type of printed number, font size, character typesetting mode, decoration type, alignment mode, printed content and the like.
The prompt is defined by the wire harness production enterprise and can be a byte, a data type or a language character corresponding to letters, words or self-defined symbols.
The data segment complete body refers to a byte, a data type or a language character corresponding to a combination of a prompt representing the data segment and a numerical value or parameter having (or embodied by) an independent meaning represented by the data segment.
The separator may be a comma, semicolon, quotation mark, or other symbol specified by the harness manufacturer corresponding to a byte, data type, or linguistic character. If no separator is obvious, each data segment with independent meaning in the data packet can be obtained according to the sorting position of each data segment in the data packet
2) Calibrating the position of the required data
After the sorting rule of the production data in the wire harness production enterprise is known, the position of each data segment related to the printing content on the wire number pipe is calibrated, namely the number of the sequence positions of the required data segments in the sorting is extracted. (hereinafter, the position number corresponding to the data of the position to be marked is referred to as the number to be marked).
3) Establishing initial model (initial model of automatic identification screening module) in online pipe marking machine
Through the input system of the spool marking machine capable of automatically identifying the printing data, the editing rule and the serial number marking number which are set by a wire harness production enterprise aiming at the production data are input into a microprocessor of a main control circuit in the spool marking machine to establish an initial model of an automatic identification screening module, so that the initial model can know what the independent meaning of each data segment in the data packet is.
4) Spool numbering for printing spool
The initial model separates the data segment related to the line number data from the received data packet related to the production data according to the editing rule and the serial number, stores the data segment in the microprocessor, converts the data segment into the printer language of the spool numbering machine, and then edits the data segment stored in the microprocessor into printing content (namely spool number) according to the printer language of the spool numbering machine and prints the printing content (namely the spool number) on the corresponding line number pipe.
5) Error correction
When the printed content output by the printer deviates from the desired printed content, the error needs to be manually corrected and the correct printed content needs to be input again, so that the printer knows where the error is and what the error is. The method comprises the steps of entering a manual error correction mode through a human-computer interface of the spool marking machine, inputting the correct printing language into the machine aiming at the wrong segment number (namely a prompt), and telling the automatic identification screening module what printing language to convert into is correct.
The following two common error corrections are available:
for one, an error caused by manual input, such as inputting an error in a prompt for some data segments when the initial learning content (i.e. the editing rule and the number of sequence numbers) is manually input, results in a value or parameter that should not appear under the prompt, i.e. data with different attributes and independent meanings appear under the prompt.
When the errors occur, the initial model gives a prompt dialog box through a human-computer interface, and correct answers are given manually.
Secondly, the errors caused by some misreadings of a plurality of production data generated by the initial model are corrected manually.
6) Continuous perfection model
Through the input of mass production data in daily production, the data storage of data sections with the same position and attribute is enriched, so that the automatic identification screening module can continuously perform self-learning.
7) And continuously correcting the error, so that the automatic identification screening module gradually establishes a correct identification rule.
The automatic identification screening module of the invention enables the printer to know where the required content is and the independent meaning of the content representation of each data segment through the steps of 'initial learning' (the aforementioned '1)' to '5)', so that the printer has the capability of separating the printing content from the production data; and the printer can be basically used correctly through the subsequent rule of perfecting data by correcting errors.
By "in-depth learning" (aforementioned "6 th) -7 th)" steps), the printer separates the print contents according to the preliminarily formed data rules and establishes rules in depth, such as what contents the well-positioned data segment has, those contents are right, and those are wrong.
After a certain amount of data is deeply learned, the working mode of the printer automatically searches the data content required by the printer in a content-first mode (the working mode of the printer in the initial learning mode carries out data identification in a position-first mode), and even if the position of the required printing data in the production data is changed, the capability of the automatic identification screening module for correctly identifying the relevant data is not influenced.

Under the rotation of the tube pressing motor 69, the front support arm 52 in the front pressing assembly 50 and the rear support arm 62 in the rear pressing assembly 60 move in opposite directions in synchronization in the vertical direction.
Working process of the front pressing assembly 50 and the rear pressing assembly 60:
as shown in fig. 7, 8 and 9, when the spool marking machine is started to prepare for printing, the head end of the spool firstly enters the conveying assembly 40 from the spool inlet 20, and before the head end of the spool enters the centering assembly 43 from the conveying assembly 40, the pressing pipe motor 69 rotates counterclockwise (with reference to fig. 8), the front support arm 52 in the front pressing assembly 50 rises, so that the gap between the front pressing pipe wheel 51 and the driving roller 59 below the front pressing pipe wheel is enlarged, and a passage is opened for the head end of the spool to pass through the driving roller 59 and enter the centering assembly 43.

As shown in fig. 12-14, includes a print base 71, a print head 72.
The printing head 72 of the line pipe marking machine capable of automatically identifying the printing data moves downwards when printing, and the following structure is adopted:
the print motor 701 drives the vertically disposed hold-down link 73 through gear transmission, the hold-down link 73 compresses the print spring 74 to provide downward pressure to the print base 71, and the print head 72 is disposed at the lower end of the print base 71.
In order to make the pressure of the printing head 72 on the line pipe uniform during printing, the line pipe marking machine capable of automatically identifying the printing data is provided with a flat pressing assembly in the printing head assembly 70, and the flat pressing assembly can automatically adjust the pressure of the printing head 72 on the line pipe.

2. Tension detection assembly for ribbon 78
As shown in fig. 10 and 11, the line pipe marking machine capable of automatically identifying printing data is provided with ribbon tension detecting assemblies at the front and back sides of the print head 72 of the line marking assembly, namely a front ribbon tension detecting assembly 81 and a back ribbon tension detecting assembly 82, which respectively have the following functions:
generally, the diameter of the ribbon (original new ribbon) 78 wound on the unwinding spool 771 and the diameter of the ribbon (recovered ribbon after printing) 78 wound on the winding spool 772 of the ribbon 78 dynamically change during the printing process, that is, the diameter of the ribbon 78 on the unwinding spool 771 gradually decreases and the diameter of the ribbon 78 on the winding spool 772 gradually increases as the printing operation progresses.
In order to ensure the printing effect, the ribbon 78 needs to be transported at a uniform speed, i.e., the linear speed of unwinding the ribbon 78 and winding the ribbon 78 is the same (in this case, the ribbon unwinding shaft 771 and the ribbon winding shaft 772 of the ribbon 78 are controlled by different driving devices).
At the beginning of printing, since the diameter of the ribbon 78 on the unwinding roll 771 is larger than that of the ribbon 78 on the winding roll 772, in order to keep the ribbon 78 running at a constant speed, the angular velocity of the unwinding roll 771 is required to be smaller than that of the winding roll 772; when the diameter of the ribbon 78 on the take-up spool 772 is larger than the diameter of the ribbon 78 on the pay-off spool 771, the angular velocity of the take-up spool 772 is required to be smaller than the angular velocity of the pay-off spool 771, that is: during printing, as the diameter of the ribbon 78 on the take-up spool 772 gradually increases, the corresponding angular velocity should decrease; as the diameter of the ribbon 78 on the payout roll 771 gradually decreases, the corresponding angular velocity should increase. The technical scheme involved in real-time adjustment of the angular velocities of the unreeling shaft 771 and the reeling shaft 772 is complex in structure, multiple in components, high in control difficulty and high in cost.
If the unwinding shaft 771 and the winding shaft 772 adopt constant angular speeds (in this case, the unwinding shaft 771 and the winding shaft 772 can share the same driving device), the ribbon unwinding speed and the ribbon winding speed are high and the ribbon 78 before the printing head 72 is loose and accumulated at the early stage of the printing process (when the diameter of the ribbon 78 on the unwinding shaft 771 is larger than that of the ribbon 78 on the winding shaft 772); at the later stage of the printing process (when the diameter of the ribbon 78 on the unwinding spool 771 is smaller than that of the ribbon 78 on the winding spool 772), the unwinding speed is slow, the winding speed is fast, and the tension of the ribbon 78 is gradually increased, which leads to the breakage of the ribbon when the tension is severe.
The unwinding shaft 771 and the winding shaft 772 of the spool marking machine capable of automatically identifying the printing data are respectively connected with different driving devices, the ink ribbon tension detection assembly 81 on the front side is arranged between the unwinding shaft 771 and the printing head 72, and the ink ribbon tension detection assembly 82 on the rear side is arranged between the printing head 72 and the winding shaft 772. When the unwinding linear velocity is greater than the winding linear velocity, which results in the ribbon 78 being loose and stacked, or the unwinding linear velocity is less than the winding linear velocity, which results in the tension of the ribbon 78 being too large, the ribbon tension detecting assemblies 82 on the front and rear sides can notify the unwinding shaft 771 and the winding shaft 772 to adjust the rotation speeds thereof according to the collected information.
The front and rear ribbon tension detection assemblies 82 are identical in construction and include a tension sensing arm 86, a swivel 85, a tension spring 88 and a sensor.
The tension sensor arm 86 is a straight rod, and is disposed perpendicular to the rotating frame 85, the root thereof is fixed to the rotating frame 85, and the arm lever portion thereof is pressed against the corresponding front ribbon 78 or rear ribbon 78.
One end of the extension spring 88 is fixed on the power base plate 33, the other end is hooked on the root of the tension sensing arm 86, and the rotating frame 85 is fixed on the power base plate 33 through a supporting shaft.
When the ribbon 78 is loosened, the tension sensor arm 86 is under the action of the extension spring 88 (the tension sensor arm 86 moves towards the tension direction of the extension spring 88), so that the rotating frame 85 can rotate, when the rotation angle or the displacement deviates from the normal set range, the sensor can transmit the information to the main control circuit, and the unwinding speed or the winding speed is controlled by the main control circuit to make corresponding adjustment.
When the tension of the ribbon 78 is large, the ribbon 78 is tightened to cause the tension sensing arm 86 to move in a direction opposite to the tension of the tension spring 88, and the rotating frame 85 can also rotate, and when the rotation angle or the displacement deviates from the normal set range, the sensor can transmit the information to the main control circuit, and the unwinding speed or the winding speed is controlled by the main control circuit to make corresponding adjustment.
The sensor can be a potentiometer, an angle sensor, a displacement sensor and a pull pressure sensor.
The ribbon tension detecting assembly can adjust the angular velocity of the unwinding shaft 771 and the winding shaft 772 in real time (meanwhile, the linear velocity is changed correspondingly), so that the tension degree of the ribbon 78 on the two sides of the printing head 72 is improved, the ribbon 78 cannot wrinkle or break in the whole printing process, and the frequency of replacing consumables is reduced.

The detection plate 84 is a rectangular flat plate and is fixed on the power substrate 33, the detection plate 84 and the rotating frame 85 are arranged in an overlapping mode, the rotating frame 85 can rotate relative to the detection plate 84, the Hall sensor 83 is arranged in the notch 87, when the rotating frame 85 rotates along with the change of the tightness degree of the color ribbon 78, the upper magnetic block 851 and the lower magnetic block 852 can change the distance between the Hall sensor 83 and the upper magnetic block 851 and the lower magnetic block 852, and therefore the Hall sensor 83 can acquire the information that the color ribbon 78 is in a loose or tight state.
When the hall sensor 83 is disposed at the middle position between the upper magnetic block 851 and the lower magnetic block 852, the included angle formed by the color stripes 78 on both sides of the tension sensing arm 86 can be adjusted by 150 degrees, and when the included angle is beyond 135 degrees and 165 degrees, the rotation angle of the rotating frame 85 can be considered to deviate from the normal set range.
