In the embodiment of the present sequence, the cable stops running and the stay time is Tc when the wire cutting operation is performed.
It should also be noted that in the specific embodiment of the present timing, the cable continues to run during the printing operation. Optionally, the cable is stopped during the printing operation.
The average speed of the cable run is also shown as v; printing time is T/v; the operation time length of the cable between two adjacent character strings of the adjacent wiring sections is (H+B)/v; the duration between the printing start time of the front-end identification character string and the front-end line cutting operation start time is (delta-H)/v; and between two wire cutting operations, the wire-feeding time length of the wire-feeding control signal is L/v.

Fig. 6 is a flowchart of an embodiment of a wiring identification method of the present application. The wiring identification method of the application comprises a data input step (step 101), a cable motion control step (step 102), a printing operation step (step 103) and a wire cutting operation step (step 104), and specifically comprises the following steps:
step 101, inputting an identification character string and a wiring length value into a data unit;
102, controlling a wire feeding device to enable a cable to move along the length direction, and outputting a feedback signal, wherein the feedback signal comprises a cable movement displacement value;
step 103, comparing the feedback signal with the wiring length value, and sending a printing control signal to a printing head when the difference between the cable motion displacement value and the integral multiple of the wiring length corresponds to the printing position;
in particular, in the embodiment shown in fig. 1-2, the comparing unit sends a second trigger signal to the print control unit; and the printing control unit sends a printing control signal to the printing head, and the printing head receives the character string data to perform printing operation.
104, comparing the feedback signal with the wiring length value, and sending a wire cutting control signal to a wire cutting device when the difference between the cable motion displacement value and the integral multiple of the wiring length corresponds to the wire cutting position;
in the embodiment shown in fig. 1-2, the comparing unit sends a first trigger signal to the wire cutting control unit; the wire cutting control unit sends a wire cutting control signal to the wire cutting device, and the wire cutting device performs wire cutting operation.
Returning to step 102.
In steps 103 to 104, the difference corresponds to a print position or a line cutting position. In the device configuration and the operation state shown in fig. 3 to 4, assuming that the print position xt=0, the trimming position xc=Δ. When the length of the produced wires is L and the number of wires is N, for example, the front end identification character string of the wires is printed from the time of x=0, the corresponding printing position is x=0, and the corresponding wire cutting position is x=Δ -H; the difference satisfies x-nl=0 and still corresponds to the print position, and the difference satisfies x-nl=Δ -H and still corresponds to the cut line position (n=0 to N). Since the front end identification character string of the wiring is printed from the time of the wiring length x=0, the rear end identification character string of the wiring is printed from the time of x=l-H-B-T, and thus the difference satisfies x-nl=h+b+t, corresponding to the print positions (n=1 to N). Therefore, according to the difference value, the corresponding printing position or wire cutting position of the cable motion displacement value can be judged; the print location further comprises a front end identification string print location and a back end identification string print location.
Fig. 7 is a flowchart of an embodiment of print preference of the wiring identification method of the present application. Based on the embodiment shown in fig. 6, the steps added are: and in the time period when the printing head receives the printing control signal, if the difference value corresponds to the wire cutting position, the wire cutting control signal is forbidden to be sent to the wire cutting device, and after printing is finished, the wire feeding device is controlled to enable the wire to return to the wire cutting position, so that wire cutting operation is performed. The specific steps are as follows:
step 201, inputting an identification character string and a wiring length value into a data unit;
step 202, controlling a wire feeding device to enable a cable to move along the length direction, and outputting a feedback signal, wherein the feedback signal comprises a cable movement displacement value;
step 203, comparing the feedback signal with the wiring length value, and sending a printing control signal to a printing head when the difference between the cable motion displacement value and the integral multiple of the wiring length corresponds to the printing position;
step 203A, comparing the feedback signal with the wire length value within a duration range in which the print head receives a print control signal (i.e., the print head performs a printing operation);
when the difference between the cable motion displacement value and the integral multiple of the wiring length corresponds to the wire cutting position (conflict occurs), the printing operation is prioritized, the wire feeding device is controlled to return the cable to the wire cutting position after the printing is finished, a wire cutting control signal is sent to the wire cutting device, the wire cutting operation is carried out, and the step 202 is returned after the wire cutting is finished;
if no case occurs in which the difference between the cable motion displacement value and the integer multiple of the wiring length corresponds to the trimming position (conflict does not occur), step 204 is performed after the printing is completed;
step 204, comparing the feedback signal with the wiring length value outside the range of the duration of the printing control signal received by the printing head, and sending a wire cutting control signal to a wire cutting device when the difference between the cable motion displacement value and the integer multiple of the wiring length corresponds to the wire cutting position; returning to step 202.
FIG. 8 is a flow chart of a preferred embodiment of the wire-cutting method of the present application. Based on the embodiment shown in fig. 6, the steps added are: and within the time period when the printing head receives the printing control signal, if the difference value corresponds to the wire cutting position, stopping the printing operation, sending the wire cutting control signal to the wire cutting device, and continuing the printing operation after the wire cutting operation is finished. The specific steps are as follows:
step 301, inputting an identification character string and a wiring length value into a data unit;
step 302, controlling a wire feeding device to enable a cable to move along the length direction, and outputting a feedback signal, wherein the feedback signal comprises a cable movement displacement value;
step 303, comparing the feedback signal with the wiring length value, and sending a printing control signal to a printing head when the difference between the cable motion displacement value and the integral multiple of the wiring length corresponds to the printing position;
step 303A, comparing the feedback signal with the wire length value within a range of time periods in which the print head receives the print control signal (i.e., the print head performs a printing operation);
if the difference between the cable motion displacement value and the integral multiple of the wiring length corresponds to the wire cutting position (conflict occurs), stopping the printing operation, and sending a wire cutting control signal to a wire cutting device by a wire cutting control unit, and continuing the printing operation after the wire cutting operation is finished;
the printing operation is stopped, and the printing control unit stops printing control signals, and the wire feeding control unit stops wire feeding control signals, so that the printing head works to finish part of the identification character string;
continuing the printing operation, wherein the printing control unit continues to send out a printing control signal, the wire feeding control unit continues to send out a wire feeding control signal, and the printing head prints the rest part of the identification character string;
step 304, comparing the feedback signal with the wiring length value outside the range of the duration of the printing control signal received by the printing head, and sending a wire cutting control signal to a wire cutting device when the difference between the cable motion displacement value and the integer multiple of the wiring length corresponds to the wire cutting position; returning to step 302.
It should be noted that, in one embodiment of the present application, when the cable corresponds to the wire cutting position, the wire feeding control unit will suspend the wire feeding control signal for Tc; when the wire cutting operation is completed, the wire feeding control unit continues to send a wire feeding control signal. The wire cutting control unit should send out an indication signal whether the wire cutting operation is completed. As a further optimized embodiment of the device of the present application, the wire cutting control unit 5 is connected to the wire feeding control unit 4 through a first status monitoring port R5, and is configured to transmit a first status monitoring signal. The first state monitoring signal comprises an indication signal of whether the wire cutting operation is finished or not.
It should also be noted that in one embodiment of the application, when the cable corresponds to the printing position, the print head starts the printing operation while the wire feeding device continues to operate.
