Description

Technical Field

[0001] The invention belongs to the technical field of wire processing, and in particular relates to a method for using a vehicle-mounted HSD wire harness terminal punching and sheathing machine. Background Art

[0002] Terminal punching refers to the process of pressing the hardware head of the wire to the end of the wire. After that, through conduction, the punched terminal can be connected without welding, which is convenient to use. The sheath, as the surface protective material of the wire and the terminal, needs to be accurately covered on the surface of the wire and the terminal to play a protective effect on them.

[0003] However, today's terminal crimping and sheathing machines require manual control to complete the terminal crimping and sheathing process. This process requires high professional quality of the operators, and it is not easy to train professionals, the efficiency is low, the precision of the finished product cannot be well controlled, and the cost is high.

[0004] Therefore, the existing terminal crimping and sheathing machines cannot meet the needs in actual use, so there is an urgent need for improved technology in the market to solve the above problems. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a method for using a vehicle-mounted HSD wire harness terminal crimping and sheathing machine, which solves the problems mentioned in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The present invention is a method for using a vehicle-mounted HSD wire harness terminal crimping and sheathing machine, comprising the following steps:

[0008] Step 1: Enter the standard parameters of the target wire to be processed, and analyze the terminals and sheaths required to be configured for the target wire processing according to the entered parameters;

[0009] Step 2: Select the terminals and sheaths configured according to the adaptability requirements and put them into the feeding equipment, start the terminal and sheath machine to start the target wire processing;

[0010] Step 3: Analyze the terminal and sheath installation points of the target wire to be processed, simulate the terminal movement, and determine whether the terminal point is at the center of the terminal end of the target wire to be processed;

[0011] Step 4: If the result of step 3 is yes, the terminal operation is started for the target wire to be processed, and after the terminal operation is completed, the connection strength of the terminal position of the target wire to be processed is detected;

[0012] Step 5: If the result of step 3 is negative, the target wire is conveyed for fine adjustment of the terminal position, and step 3 is executed again after the target wire is finely adjusted;

[0013] Step 6: During the terminal and sheathing process of processing the target wire, the terminal and sheathing machine records the operation data in real time to generate a report file. After the equipment finishes running, the report file is packaged and sent to the user end.

[0014] Furthermore, the standard parameters of the target wire specifications in step 1 include: the target wire diameter value, the target wire strand number, the target wire color and the target wire arrangement order.

[0015] Furthermore, the terminal crimping and sheathing machine performs a logical memory for sorting the colors of the target wires to be processed, and is provided with a self-starting program, which starts the processing procedure for sorting the colors of the wires according to the logical memory for sorting the colors of the wires when there is no user intervention.

[0016] Furthermore, step Step 1 includes a sub-step Step 11: analyzing the material properties of the rubber sheath on the surface of the target wire to be processed, obtaining the production date of the target wire to be processed, and calculating the reserved diameter space of the sheath based on the material properties of the rubber sheath on the surface of the target wire to be processed and the production date of the wire in combination with the operating environment temperature of the terminal crimping and sheathing machine.

[0017] Furthermore, the step Step2 is provided with sub-steps, including the following steps:

[0018] Step 21: Analyze the operation risk positions on the surface of the terminal crimping and sheathing machine and install a trigger alarm grating;

[0019] Step 22: Set up a control program to synchronously trigger the terminal crimping and sheathing machine to stop running when the trigger alarm grating is blocked by an obstacle.

[0020] Furthermore, in the step Step 4, the wires detected to have unqualified connection strength at the terminal position of the processing target wires are marked and transmitted, the functionality and integrity of the unqualified processing target wires are evaluated, and the unqualified processing target wires are discarded or terminalized according to the evaluation results.

[0021] Furthermore, after each terminal crimping and sheathing machine completes the processing of the target wire, the finished wires are sampled and tested. When the sampling test results show that the qualified rate of the finished wires is less than 95%, all the finished wires are tested one by one. When the sampling test results show that the qualified rate of the finished wires is ≥95%, the processing procedure of the target wire is completed.

[0022] Furthermore, the contents recorded in the report file in Step 6 include: the start and end time of the equipment; the time point when the equipment suddenly stops during operation; the length of time the equipment is running and the frequency of the equipment processing wires.

[0023] Furthermore, sudden stops during equipment operation include manual control stops and equipment failure stops. When equipment failure causes sudden stops in equipment operation, the equipment stops running and packages the current report file content and sends it to the user end.

[0024] Furthermore, the value of the reserved diameter space of the sheath in Step 11 is taken with reference to the calculation formula of the thermal expansion coefficient, which is as follows:

[0025] β = (1 / V) [(dV) / (dt)];

[0026] Where β is the volume expansion coefficient of the target wire to be processed;

[0027] V is the target wire volume for processing;

[0028] d is the outer diameter of the target wire to be processed;

[0029] t is the current processing target wire processing environment temperature (℃).

[0030] The present invention has the following beneficial effects:

[0031] 1. The present invention provides a method for using a vehicle-mounted HSD wire harness terminal crimping and sheathing machine for use in the operation of the terminal crimping and sheathing machine. Through this method, the situation of manually cooperating with the operation of the equipment to process the wires can be eliminated, thereby making the operation of the terminal crimping and sheathing machine more intelligent.

[0032] 2. The present invention deploys a trigger alarm grating, which can effectively provide a certain safety guarantee for the operator, and avoid the operator's careless operation during inspection, feeding and other operations, resulting in production accidents.

[0033] 3. The present invention can effectively calculate the size of the sheath required for the wire sheathing, and can take environmental factors into consideration during the wire sheathing process, thereby preventing the sheath and the wire surface from expanding and failing to match due to uncertain factors such as ambient temperature and humidity, resulting in the qualified rate of the sheathing failing to reach the expected level.

[0034] 4. The present invention obtains equipment operation data to form a report file to provide feedback on the execution status of processing tasks to the user end of the equipment, thereby effectively improving the convenience of the user end in using and managing the equipment.

[0039] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0040] Example 1

[0041] See also Figure 1 As shown, the present invention is a method for using a vehicle-mounted HSD wire harness terminal crimping and sheathing machine, comprising the following steps:

[0042] Step 1: Enter the standard parameters of the target wire to be processed, and analyze the terminals and sheaths required to be configured for the target wire processing according to the entered parameters;

[0043] Step 2: Select the terminals and sheaths configured according to the adaptability requirements and put them into the feeding equipment, start the terminal and sheath machine to start the target wire processing;

[0044] Step 3: Analyze the terminal and sheath installation points of the target wire to be processed, simulate the terminal movement, and determine whether the terminal point is at the center of the terminal end of the target wire to be processed;

[0045] Step 4: If the result of step 3 is yes, the terminal operation is started for the target wire to be processed, and after the terminal operation is completed, the connection strength of the terminal position of the target wire to be processed is detected;

[0046] Step 5: If the result of step 3 is negative, the target wire is conveyed for fine adjustment of the terminal position, and step 3 is executed again after the target wire is finely adjusted;

[0047] Step 6: During the terminal and sheathing process of processing the target wire, the terminal and sheathing machine records the operation data in real time to generate a report file. After the equipment finishes running, the report file is packaged and sent to the user end.

[0048] The value of the reserved diameter space of the sheath in Step 11 refers to the calculation formula of the thermal expansion coefficient, which is as follows:

[0049] β = (1 / V) [(dV) / (dt)];

[0050] Where β is the volume expansion coefficient of the target wire to be processed;

[0051] V is the target wire volume for processing;

[0052] d is the outer diameter of the target wire to be processed;

[0053] t is the current processing target wire processing environment temperature (℃).

[0054] Example 2

[0055] In terms of specific implementation, based on Example 1, this example refers to Figure 1 The following is a further detailed description of the method for using the vehicle-mounted HSD wiring harness terminal crimping and sheathing machine in Example 1:

[0056] like Figure 1 As shown, the standard parameters of the target wire specifications in step 1 include: the target wire diameter value, the target wire strand number, the target wire color and the target wire arrangement order.

[0057] like Figure 1 As shown, the terminal crimping and sheathing machine performs a wire color sorting logic memory for the target wires to be processed, and is provided with a self-starting program. The self-starting program starts the processing procedure of sorting the wire colors according to the wire color sorting logic memory when the user does not intervene in the operation.

[0058] Through this setting, the terminal crimping and sheathing machine can be effectively improved to have a certain learning ability after long-term use, so that the terminal crimping and sheathing machine can be more in line with the user's operating habits, thereby achieving the purpose of improving the equipment's operating efficiency for wire processing.

[0059] like Figure 1 As shown, step Step 1 includes sub-step Step 11: analyzing the material properties of the rubber sheath on the surface of the target wire to be processed, obtaining the production date of the target wire to be processed, and calculating the reserved diameter space of the sheath according to the material properties of the rubber sheath on the surface of the target wire to be processed and the production date of the wire combined with the operating environment temperature of the terminal crimping and sheathing machine.

[0060] This setting can assist the method of the present invention to make further judgments, provide more accurate calculations for the sheathing process of the wire after the terminal is completed, and ensure that the sheath used for the wire is more suitable for the wire. This not only improves the quality of the finished wire processing products, but also achieves the purpose of saving raw materials to a certain extent.

[0061] like Figure 1 As shown, step 2 is provided with sub-steps, including the following steps:

[0062] Step 21: Analyze the operation risk positions on the surface of the terminal crimping and sheathing machine and install a trigger alarm grating;

[0063] Step 22: Set up a control program to synchronously trigger the terminal crimping and sheathing machine to stop running when the trigger alarm grating is blocked by an obstacle.

[0064] This setting ensures that the device stops running when there are user limbs around the processing parts of the device, providing a certain degree of safety protection for the operator.

[0065] like Figure 1 As shown, in step Step 4, the wires detected to have unqualified connection strength at the terminal position of the processing target wires are marked and transmitted, the functionality and integrity of the unqualified processing target wires are evaluated, and the unqualified processing target wires are discarded or terminalized according to the evaluation results.

[0066] This setting can effectively avoid the waste of defective products, ensure secondary inspection of unqualified products, screen out reusable wires from unqualified products, and greatly reduce losses in the production process.

[0067] like Figure 1 As shown, after each terminal crimping and sheathing machine completes the processing of the target wire, the finished wires are sampled and tested. When the sampling test results show that the qualified rate of the finished wires is less than 95%, all the finished wires are tested one by one. When the sampling test results show that the qualified rate of the finished wires is ≥95%, the processing procedure of the target wire is completed.

[0068] like Figure 1 As shown, the contents recorded in the report file in step 6 include: the start and end time of the equipment; the time point when the equipment suddenly stops during operation; the length of time the equipment is running and the frequency of the equipment processing wires.

[0069] like Figure 1 As shown, sudden stops during equipment operation include manual control stops and equipment failure stops. When equipment failure causes sudden stops, the equipment stops running and packages the current report file content and sends it to the user end.

[0070] This setting can provide timely feedback to the user when a device fails, ensuring that the user is aware of the cause of the device failure in the first place and ensuring the efficiency of device failure handling.

[0071] In summary, the present invention provides a method for using a vehicle-mounted HSD wire harness terminal crimping and sheathing machine for use in the operation of the terminal crimping and sheathing machine. Through this method, the situation of manually cooperating with the operation of the equipment to process the wires can be eliminated, thereby making the operation of the terminal crimping and sheathing machine more intelligent. In addition, a trigger alarm grating is deployed in the present invention, which can effectively provide a certain safety guarantee for the operator, and avoid the operator's careless operation during inspections, loading and other operations, resulting in production accidents. In addition, the present invention can effectively calculate the size of the sheath required for the wire sheathing, and can take environmental factors into consideration during the process of wire sheathing, so as to avoid the sheath and the surface of the wire expanding and matching due to uncertain factors such as ambient temperature and humidity, resulting in the qualified rate of the sheathing failing to reach the expected level. In addition, the equipment operation data is obtained to form a report file to provide feedback to the user end of the equipment on the execution of the processing task, which effectively improves the convenience of the user end in using and managing the equipment.

[0072] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments, any equivalent replacement of some of the technical features therein, and any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
