[0002] It should be noted that the contents recorded in this section do not represent all prior art.

[0003] With the development of electronic product technology, electronic products are gradually modularized. As the amount of information transmitted between modules increases, the information transmission between electronic modules is usually connected by wiring. Take the production of medical B-ultrasound ultra-fine coaxial lines as an example: (B-ultrasound probe harnesses generally have nearly 200 signal lines) In the prior art, operators use conducting tools such as buzzers to manually sort the wires at both ends of A and B in fixed wire ducts, fix them with tape, and then flow them into subsequent processing. The manual wire separation method is used. Due to the large number of wires, small wires, and the same color, it is easy to put them in the wrong wire duct, which is not only inefficient, but also often causes misalignment. Therefore, it is necessary to improve the prior art to solve the above problems. Summary of the invention

[0041] Please also refer to Figure 1-Figure 6 This embodiment provides a wire splitting method and an automatic wire splitting machine using the wire splitting method, which is mainly used for wiring signal connection lines in electronic equipment. In this embodiment, it can be the production of medical B-ultrasound ultra-fine coaxial cable as an example.

[0042] This embodiment provides an automatic wire splitting machine, the wire splitting machine 200 includes a wire splitting machine body 60, a wire arrangement board 20, a positioning claw 30, a sensor 40 and a servo module 50. The wire splitting machine body 60 is also provided with a program control module (not shown). Figure 3 The structure of the wiring board 20 in one embodiment of the present application is shown. Figure 3 It can be seen that the upper surface of the wiring board 20 is provided with a plurality of wire grooves 201 arranged in a transverse manner for clamping the wires 101 .

[0043] Figure 5The structure of the positioning claw 30 in one embodiment of the present application is shown. Figure 5 It can be seen that the positioning claw 30 includes a first wire claw 31 and a second wire claw 32 arranged on one side of the wire groove 201, and a press-in entrance 301 for allowing the wire 101 to enter the wire groove 201 is provided between the first wire claw 31 and the second wire claw 32; further, one side of the first wire claw 31 and the second wire claw 32 are respectively installed on the wire splitter body 60 through a first bracket 33 and a second bracket 34, wherein, in some embodiments, taking the first bracket 33 as an example, the first bracket 33 is provided with a first adjusting member 35 and a second adjusting member 36 that enable the first wire claw 31 to be displaced in the spatial orientation, so that the press-in entrance 301 is located at a suitable position in the wire groove 201, ensuring that the wire 101 passes smoothly.

[0044] In addition, if Figure 6 As shown, taking the first bracket 33 as an example, the first wire claw 31 is provided with a bottom surface 310 on the side facing the wire groove 201, and a top surface 311 on the side away from the wire groove 201, and the top surface 311 is inclined toward the bottom surface 310 to form an angle not greater than 90 degrees, so that the wire 101 can smoothly enter the wire groove 201.

[0045] Figure 3 The servo module 50 structure in one embodiment of the present application is also shown. Figure 3 It can be seen that the servo module 50 includes a mobile platform 51 connected to the wiring board 20 and a servo motor 52 that drives the mobile platform 51 to move. The servo motor 52 is controlled by a program control module, and the program control module sends an electrical signal to the servo motor 52 to drive the mobile platform 51 to move horizontally.

[0046] Please also refer to Figure 1 The line splitting method of the present invention comprises the following steps:

[0047] 1) dividing the wire harness 100 into an A end having a plurality of defined wire groups 10 and a B end having a plurality of defined wire groups 10, wherein each defined wire group 10 comprises a plurality of wires 101;

[0048] 2) arbitrarily processing the A end or the B end to determine a number of wires 101 of the wire group 10, and connecting the processed wires 101 to the program control module;

[0049] 3) Inputting the wiring parameters of the wire harness 100 to be processed into the program control module;

[0050] 4) The sensor 40 collects any unsorted single wire 101 of the wire group 10 to be processed to obtain an electrical signal of the single wire 101. The program control module processes the electrical signal according to the wiring parameters to obtain a displacement signal, and sends the displacement signal to the servo module 50. The servo module 50 drives the wiring board 20 to move to the corresponding wire slot 201 of the single wire 101 according to the displacement signal.

[0051] It should be noted that: in the above steps, the determined wire group 10 at the A end and the determined wire group 11 at the B end are respectively determined to be corresponding to four groups, the wires A1, A2, A3... of one of the determined wire groups 10 at the A end are determined in the determined wire group 10, and the wires B1, B2, B3... at the B end are determined in the determined wire group 11. The present wire division method is: arbitrarily process the wires of the determined wire group 10 at the A end (or B end) of the wiring harness, connect them to the welding socket or the PCB substrate, and then connect them to the signal end of the automatic wire division machine 200, and the unprocessed wires at the other end can be conducted and sorted by the automatic wire division machine 200.

[0052] Then, the program control module in the wire splitter 200 pre-programs the corresponding line sequence of the AB end, such as: inputting the serial number of the current product in the program, dividing the product into several steps (such as 4 steps, the number of steps is determined in accordance with the number of wire groups), and then setting the slot parameters of the wire 101 for the current step (i.e. B3 should be moved to the first slot to correspond to A1), setting the running speed of the wiring board 20, setting the origin and starting point, and setting the spacing between two adjacent wires 101. The program control module can store multiple sets of programs, and the operation interface uses a touch screen, with a display function of the sensor touching the current wire 101 and a buzzing prompt function.

[0053] In some cases, the B end B1 may not be in the determined wire group 10 (A1, A2, A3, ...) of the A end. Therefore, in this case, the steps further include: determining whether the single wire (such as B1) is in the previously set parameter step 1; if the single wire (B1) is in the current parameter, a displacement signal is obtained, and the next step is continued; if the single wire is not in the current parameter, a prompt signal (buzzing) is triggered, and the operation interface shows that the current wire 101 is in the second step, the third step or the fourth step. At this time, the user can move it to Figure 4 The pressing head 55 shown is waiting for the next step and then moved to the corresponding position.

[0054] Figure 3 , 4 The structure of the pressure head 55 where the wire 101 not in the current step is placed is shown. Figure 3 , Figure 4It can be seen that a wire crimping seat 53 is provided on one side of the mobile platform 51, and a wire crimping device 54 for fixing the wire harness 100 is provided on the wire crimping seat 53. The wire crimping seat 53 is provided with a plurality of pressing heads 55 for separating multiple groups of wires to be processed. The pressing heads 55 are threadedly connected to the wire crimping seat 53, so that the redundant or misplaced single wire 101 in the above-mentioned embodiment can be restricted on the wire crimping seat 53.

[0055] In some embodiments, Figure 3 As shown, in order to improve the accuracy of the servo module 50, a sensing sheet 56 is provided on the mobile platform 51, and a sensor 57 is provided on the moving path of the sensing sheet 56. The sensor 57 is electrically connected to the program control module. When the sensing sheet 56 moves to the sensor 57, the sensor 57 triggers an electrical signal.

[0056] In addition, if Figure 6 As shown, the bottom surface 310 of the first wire claw 31 and the second wire claw 32 extends downward on the side close to the pressing inlet 301 to form a protrusion 312. When the servo motor drives the wiring board 20 to move, the setting of the protrusion 312 can achieve the purpose of reducing the contact area between the first wire claw 31 and the second wire claw 32 and the wiring board 20.

[0057] Through reading and understanding the above-mentioned specific embodiments, technicians in the relevant technical field can easily implement the present invention. For example, after the wire splitter 200 is turned on, the display screen shows the barcode of this product, and the user needs to use a scanner to scan the barcode to record the current operation, including time, operator name, operation data, etc. However, it should be understood that the present invention is not limited to the specific embodiments described above. On the basis of the disclosed embodiments, technicians in the basic field can arbitrarily combine different technical features to achieve different technical solutions. For example, the wiring board 20 is fixed on the wire splitter body 60, and the servo module 50 is connected to the positioning claw 30 to drive the positioning claw 30 to move to achieve automatic analysis. Therefore, the scope of protection of the present application is limited only by the scope of the attached claims.

[0058] The above specific examples are used to illustrate the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the art, according to the concept of the present invention, some simple deductions, modifications or substitutions can be made.
