Description

Technical Field

[0001] This application relates to the field of operating tool technology, and more particularly to a method for automatically identifying and crimping terminals using crimping pliers. Background Technology

[0002] In existing technologies, manual crimping tools are typically used to crimp terminals. However, in practice, manual crimping tools have many drawbacks, such as:

[0003] 1. Because the types and diameters of terminals vary widely, while the shape and size of manual crimping tools are usually fixed, the application range of manual crimping tools for terminals of various sizes is relatively small, and it is often necessary to change crimping tools frequently during operation.

[0004] 2. When using manual crimping tools to crimp terminals, the crimping degree can only be judged by the experience of the workers, resulting in low crimping accuracy and a low pass rate.

[0005] 3. Manual crimping is time-consuming and labor-intensive, resulting in low work efficiency. Summary of the Invention

[0006] In view of this, the present invention provides a method for automatically identifying and crimping terminals with crimping pliers, thereby enabling automatic identification of terminal dimensions and precise crimping of terminals, improving applicability and crimping accuracy.

[0007] The technical solution of this invention is implemented as follows:

[0008] A method for automatically identifying and crimping terminals using crimping pliers, characterized in that the crimping pliers comprise: a plier body, a plier head for placing terminals, and a crimping piston for crimping terminals; the method includes the following steps.

[0009] Step 101: In the initial state, obtain the initial distance 'a' between the front end of the crimping piston and the inner wall of the clamp head;

[0010] Step 102: Place the terminal in the clamping head, and let the crimping piston extend forward from the initial position until the tip of the crimping piston contacts the terminal, and obtain the movement distance b of the crimping piston;

[0011] Step 103, calculate the terminal diameter d;

[0012] Step 104: Calculate the crimping distance L based on the terminal diameter;

[0013] Step 105: Extend the crimping piston forward by the corresponding crimping distance L to complete the crimping of the terminal.

[0014] Preferably, the crimping pliers also include a displacement sensor for real-time monitoring of the displacement of the crimping piston.

[0015] Preferably, the initial state refers to the state when the crimping pliers are unloaded and the crimping piston is not extended. The method for obtaining the initial distance 'a' between the tip of the crimping piston and the inner wall of the pliers head includes the following steps:

[0016] Step 11, set the crimping pliers to the initial state.

[0017] Step 12: Extend the crimping piston forward until the tip of the crimping piston contacts the inner wall of the clamp head;

[0018] Step 13: Use a displacement sensor to obtain the displacement of the pressing piston, which is the initial distance a.

[0019] Preferably, the crimping pliers include an identification device for identifying whether the foremost tip of the crimping piston is in contact with an object.

[0020] Preferably, the identification device is a pressure sensor used to monitor the pressure on the crimping piston. When the pressure sensor detects that the pressure value on the crimping piston exceeds a preset pressure value, it determines that the foremost tip of the crimping piston is in contact with the object.

[0021] Preferably, the identification device is a current sensor. When the current sensor detects that the current value on the crimping pliers exceeds a preset current value, it determines that the front end of the crimping piston is in contact with the object.

[0022] Preferably, the crimping pliers are hydraulic pliers, and the identification device is a pressure sensor. When the pressure sensor detects that the pressure value inside the hydraulic pliers exceeds a preset pressure value, it determines that the front end of the crimping piston is in contact with the object.

[0023] Preferably, the displacement sensor serves as an identification device. When the displacement sensor detects that the displacement data change within a unit time reaches a preset threshold, it determines that the front end of the pressing piston is in contact with the object at this time.

[0024] Preferably, the terminal diameter d is calculated by subtracting the moving distance b of the crimping piston from the initial distance a.

[0025] Preferably, step 104 includes:

[0026] Step 41, preset the crimping coefficient k;

[0027] Step 42: Multiply the terminal diameter by the preset crimping coefficient k to obtain the crimping distance L.

[0028] As can be seen above, in the method for automatic identification and crimping of terminals using crimping pliers in this invention, the terminal diameter is calculated to identify the terminal, thereby determining the degree of crimping based on the terminal diameter. This achieves automatic identification and crimping of terminals, allowing for independent identification of each terminal without being limited by terminal size, significantly improving the applicability. Furthermore, the degree of crimping of each terminal can be accurately determined based on its diameter, thus improving crimping accuracy. Attached Figure Description

[0032] To make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 1 As shown, the present invention provides a method for automatically identifying and crimping terminals using crimping pliers. The crimping pliers include: a plier body, a plier head 2 for placing a terminal 100, and a crimping piston 15 for crimping the terminal 100; the method includes the following steps.

[0034] Step 101: In the initial state, obtain the initial distance 'a' between the front end of the crimping piston and the inner wall of the clamp head;

[0035] Step 102: Place the terminal in the clamping head, and let the crimping piston extend forward from the initial position until the tip of the crimping piston contacts the terminal, and obtain the movement distance b of the crimping piston;

[0036] Step 103, calculate the terminal diameter d;

[0037] Step 104: Calculate the crimping distance L based on the terminal diameter;

[0038] Step 105: Extend the crimping piston forward by the corresponding crimping distance L to complete the crimping of the terminal.

[0039] In the technical solution of this invention, the terminal is identified by calculating the terminal diameter. Based on the terminal diameter, the crimping degree of the terminal can be further determined, realizing automatic identification and crimping of the terminal. Each terminal is identified independently, without being limited by the terminal size, which significantly improves the scope of application. Furthermore, the crimping degree of each terminal is determined based on its diameter, which improves the crimping accuracy.

[0040] The technical solution of this invention can be implemented using various methods. The following will describe the technical solution of this invention in detail using one of these implementation methods as an example.

[0041] For example, in a preferred embodiment of the invention, the crimping pliers may further include a displacement sensor for real-time monitoring of the displacement of the crimping piston.

[0042] Preferably, as an example, the displacement sensor can be installed inside the press-fit piston and arranged coaxially with the press-fit piston.

[0043] For example, preferably, in a specific embodiment of the present invention, the initial state refers to the state when the crimping pliers are in an unloaded state and the crimping piston has not extended. The method for obtaining the initial distance 'a' between the foremost tip of the crimping piston and the inner wall of the pliers head may include the following steps:

[0044] Step 11, set the crimping pliers to the initial state.

[0045] Step 12: Extend the crimping piston forward until the tip of the crimping piston contacts the inner wall of the clamp head;

[0046] Step 13: Use a displacement sensor to obtain the displacement of the pressing piston, which is the initial distance a.

[0047] Furthermore, as an example, in a preferred embodiment of the present invention, the crimping pliers may also include an identification device for identifying whether the foremost tip of the crimping piston is in contact with an object. The identification device may be a pressure sensor for monitoring the pressure on the crimping piston. When the pressure sensor detects that the pressure value on the crimping piston exceeds a preset pressure value, it is determined that the foremost tip of the crimping piston is in contact with the object at this time.

[0048] Preferably, as an example, in a specific embodiment of the present invention, the identification device may also be a current sensor. When the current sensor detects that the current value on the crimping clamp exceeds a preset current value, it determines that the foremost end of the crimping piston is in contact with the object.

[0049] Preferably, as an example, in another specific embodiment of the present invention, the crimping pliers can be hydraulic pliers, and the identification device can be a pressure sensor. When the pressure sensor detects that the pressure value inside the crimping pliers exceeds a preset pressure value, it determines that the front end of the crimping piston is in contact with the object at this time.

[0050] In another preferred embodiment of the present invention, the displacement sensor can also be used as an identification device. If the displacement sensor detects that the displacement data change within a unit time reaches a preset threshold, it is determined that the front end of the pressing piston is in contact with the object at this time.

[0051] Furthermore, as an example, in a preferred embodiment of the present invention, the method for obtaining the moving distance b of the pressing piston can be that the moving distance b of the pressing piston is monitored by a displacement sensor.

[0052] Preferably, as an example, in a specific embodiment of the present invention, the terminal diameter d can be calculated by subtracting the moving distance b of the crimping piston from the initial distance a.

[0053] Additionally, as an example, in a preferred embodiment of the present invention, step 104 may include:

[0054] Step 41, preset the crimping coefficient k;

[0055] Step 42: Multiply the terminal diameter by the preset crimping coefficient k to obtain the crimping distance L; where the value of k can be in the range of 0.3 to 0.7.

[0056] Preferably, as an example, the crimping coefficient k can be determined based on experience with the crimping degree of a large number of terminals, and the crimping distance L can be calculated using L = d × k.

[0057] Alternatively, in another embodiment of the present invention, the diameter d of the terminal can be directly obtained or measured by taking the position of the inner wall of the pliers head as the distance 0 point.

[0058] In summary, the technical solution of this invention achieves terminal identification by calculating the terminal diameter, thereby determining the crimping degree of the terminal based on the terminal diameter. This realizes automatic terminal identification and crimping, allowing for independent identification of each terminal without being limited by terminal size, significantly improving the applicability range. Furthermore, it accurately determines the crimping degree of each terminal based on its diameter, thus improving crimping accuracy.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
