Description

[0001] The present invention relates to the technical field of automobile wiring harness terminals, and in particular to an automobile wiring harness terminal bending machine and a bending control method. Background Art

[0002] The terminals in automotive connectors generally include an insulation crimping wing, a core wire crimping wing and a connecting part that are integrally formed in sequence; the insulation crimping wing is used to fix the insulation layer of the wire harness; the core wire crimping wing is used to fix the core wire of the wire harness; the connecting part is used to connect with other conductive connectors. When the terminal is assembled with the plastic shell, the connecting part often needs to be bent into a specific shape so that it can be accurately inserted into the corresponding position of the plastic shell and reliably connected with other components. For example, in order to adapt to different installation spaces and connection requirements, the connector terminals in some automotive electronic systems will be designed with a bending structure with a certain angle and shape, such as a right-angle bend, an arc bend, etc., so that it can better dock with the circuit board or other wiring harness terminals.

[0003] However, in the existing terminal crimping process, when the terminal is positioned and fixed, in order to limit the position of the connecting part of the terminal during the bending process, the end of the connecting part close to the core wire crimping wing is often pressed tightly, which can easily lead to obvious indentations on the end of the connecting part close to the core wire crimping wing after the connecting part is bent, thereby reducing the factory quality of the terminal, and the indentation may affect the conductive performance of the connecting part. Summary of the invention

[0015] In a second aspect, the present invention discloses a method for controlling the bending of automotive wire harness terminals. The method for controlling the bending of automotive wire harness terminals is applied to the automotive wire harness terminal bender in any one of the above embodiments. The method for controlling the bending of automotive wire harness terminals includes:

[0016] Step S10, based on the positioning of the core wire crimping wing and the insulation crimping wing of the terminal on the supporting part of the bender being completed, control the pressing part of the bender to press the side of the core wire crimping wing away from the supporting part;

[0017] Step S20, based on the pressing part having completed pressing the core wire crimping wing, control the bending part to move along the first direction and the second direction until the bending part reaches the first contact position of the connecting part of the terminal; the first contact position and the pressing part are on the same side of the terminal;

[0018] Step S30, based on the bending part being at the first contact position, control the bending part to move towards the terminal along the second direction, and obtain the first moving distance of the bending part;

[0026] When the terminal is positioned and fixed, the clamping position of the clamping part is adjusted to the side where the core wire crimping wing is away from the support part, so as to avoid the clamping part causing damage to the surface of the connection part and causing obvious indentations, ensuring the connection part has good electrical conductivity and good appearance. In addition, since the core wire crimping wing itself needs to be crimped and locked with the core wire of the wire harness, indentations on its surface are inevitable. Therefore, under the premise of changing the clamping position of the clamping part, the indentations on the terminal surface are reduced as much as possible, reducing the impact of the indentations on the quality of the terminal products.

[0037] In the existing crimping process of automotive wiring harness terminal 10, in order to connect with other conductive joints, the connecting portion 13 of the terminal 10 often needs to be bent at a specific angle. However, in the existing connecting portion 13 during bending, due to the positioning and fixing of the pressing portion 22, obvious indentations are likely to appear at the end close to the core wire crimping wing 12, which affects the ex-factory quality of the terminal 10 and may also affect the conductive and power-on performance of the connecting portion 13. In order to ensure the crimping quality of the terminal 10 and reduce the influence of the indentations on the surface of the terminal 10 on the performance of the terminal 10, this embodiment discloses a bending machine 20 for automotive wiring harness terminal 10.

[0038] In this embodiment, as Figure 1As shown, the bending machine 20 for automobile wiring harness terminal 10 may include a frame 25, a support portion 21, a clamping portion 22, a bending portion 23, and a driving portion. The support portion 21 is detachably connected to the frame 25, and the support portion 21 is used to support the insulation crimping wing 11 and the core wire crimping wing 12 of the terminal 10. A positioning groove may be provided at one end of the support portion 21 close to the terminal 10, so as to facilitate the positioning of the insulation crimping wing 11 and the core wire crimping wing 12. The clamping portion 22 is used to clamp the side of the core wire crimping wing 12 away from the support portion 21. The clamping portion 22 may be a rectangular block or a contoured block matching the side of the core wire crimping wing 12 away from the support portion 21, so as to facilitate the fixing of the terminal 10 and prevent the connection portion 13 of the terminal 10 from shaking when being bent. The bending portion 23 is slidably connected to the frame 25 along the first direction and the second direction. The first direction is perpendicular to the second direction. Thus, the bending portion 23 can change its own moving path when bending the connection portion 13. When the terminal 10 is positioned between the supporting portion 21 and the pressing portion 22, the bending portion 23 and the pressing portion 22 are spaced apart in the first direction, and the pressing portion 22 and the supporting portion 21 are spaced apart in the second direction. The driving portion is detachably connected to the frame 25. The driving portion drives the bending portion 23 to move in the first direction and the second direction.

[0039] Through the above-mentioned arrangement, combined with the situation that the core wire crimping wing 12 needs to crimp and lock the core wire of the wiring harness, which inevitably causes indentations on the surface of the core wire crimping wing 12, the original clamping position of the clamping portion 22 is changed, and the clamping position is adjusted to the clamping portion 22 abutting against the side of the core wire crimping wing 12 facing away from the support portion 21, thereby avoiding the clamping portion 22 causing indentation damage to the surface of the connecting portion 13 of the terminal 10, ensuring the factory quality of the terminal 10, and reducing the risk of conductive performance failure of the connecting portion 13.

[0040] In another embodiment, before the terminal 10 is bent, Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the terminal 10 of the automotive wiring harness may include an insulation crimping wing 11, a core wire crimping wing 12, and a connecting portion 13. The insulation crimping wing 11, the core wire crimping wing 12, and the connecting portion 13 are integrally formed in sequence. The insulation crimping wing 11 can be used to crimp and lock the insulation layer of the wiring harness, the core wire crimping wing 12 can be used to crimp and lock the core wire of the wiring harness, and the connecting portion 13 can be used to connect the terminal 10 to an external conductive connector. The insulation crimping wing 11 and the core wire crimping wing 12 can be set in a U-shaped structure for easy crimping.

[0041] In this embodiment, if Figure 2 As shown, the bending portion 23 includes a lower pressing seat 231 and a lower pressing shaft 232. The lower pressing shaft 232 is rotatably connected to the lower pressing seat 231. Figure 1As shown, the axis of the lower pressing shaft 232 is perpendicular to the first direction. The axis of the lower pressing shaft 232 is perpendicular to the second direction. The driving part drives the lower pressing seat 231 to move in the first direction and the second direction. By utilizing the straight cylindrical structure of the lower pressing shaft 232, during the process of bending the bending part 23 at the bending connection part 13, the rolling friction exists between the lower pressing shaft 232 and the connection part 13, so that the indentation on the surface of the connection part 13 can be reduced, and the product quality of the terminal 10 can be better protected.

[0042] In this embodiment, as Figure 1 shown, the diameter of the lower pressing shaft 232 is 30% - 60% of the length of the connection part 13 of the terminal 10. The axial length of the lower pressing shaft 232 is greater than the width of the connection part 13. The distance from the end of the connection part 13 far from the core wire crimping wing 12 to the core wire crimping wing 12 is the length of the connection part 13. When the terminal 10 is positioned between the supporting part 21 and the pressing part 22, the width direction of the connection part 13 is parallel to the axial direction of the lower pressing shaft 232.

[0043] By limiting the diameter of the lower pressing shaft 232, it can be avoided that the diameter of the lower pressing shaft 232 is too large to cause insufficient moving space during the process of bending the bending part 23 at the connection part 13, and it can also be avoided that the diameter of the lower pressing shaft 232 is too small to cause obvious indentation on the surface of the connection part 13 due to excessive pressure during the process of bending the bending part 23 at the connection part 13. By limiting the axial length of the lower pressing shaft 232, it is ensured that when the lower pressing shaft 232 abuts against the connection part 13, it can cover the surface in the width direction of the connection part 13, and it can be avoided that the end of the lower pressing shaft 232 damages the surface of the connection part 13 to form obvious indentation.

[0044] In this embodiment, as Figure 1 shown, the first direction can be the horizontal direction. The second direction can be the vertical direction. In some other embodiments, the first direction and the second direction can be set according to actual requirements, and can also be other directions.

[0045] In this embodiment, as Figure 1 shown, the automobile wire harness terminal 10 bending machine 20 may further include a profiling die 24. The profiling die 24 is detachably connected to the machine frame 25. When the terminal 10 is in the state of being crimped, the connection part 13 of the terminal 10 is pressed between the profiling die 24 and the bending part 23. Through the limitation of the profiling die 24, the connection part 13 can be quickly bent to a set angle under the drive of the bending part 23, which is convenient for standardizing the bending shape of the terminal 10 and improving the ex-factory quality of the terminal 10.

[0046] In this embodiment, this embodiment discloses a method for controlling the bending of the automobile wire harness terminal 10. The method for controlling the bending of the automobile wire harness terminal 10 is applied to the automobile wire harness terminal 10 bending machine 20 in any one of the above embodiments. As Figure 7As shown, the method for controlling the bending of the automotive wire harness terminal 10 includes steps S10 to S50. The above steps can be described in detail as follows:

[0047] Step S10, based on the positioning of the core wire crimping wing 12 and the insulation crimping wing 11 of the terminal 10 on the supporting part 21 of the bending machine 20 being completed, the pressing part 22 of the bending machine 20 can be controlled to press the side of the core wire crimping wing 12 away from the supporting part 21; by applying a fixed acting force on the core wire crimping wing 12 through the pressing part 22, a stable positioning reference can be formed to avoid the pressing part 22 causing indentations on the surface of the connecting part 13.

[0048] Step S20, based on the pressing part 22 pressing the core wire crimping wing 12 being completed, the bending part 23 can be controlled to move along the first direction and the second direction until the bending part 23 reaches the first contact position of the connecting part 13 of the terminal 10; the first contact position and the pressing part 22 are on the same side of the terminal 10; through the composite movement path of first along the first direction and then along the second direction, it can be ensured that the bending part 23 accurately reaches the predetermined contact area, thus facilitating the subsequent bending action of the bending part 23. In some embodiments, the first direction can be the horizontal direction and the second direction can be the vertical direction.

[0049] Step S30, based on the bending part 23 being located at the first contact position, the bending part 23 can be controlled to move towards the terminal 10 along the second direction to obtain the first moving distance of the bending part 23; through the vertical pressing action combined with displacement detection, the initial bending stroke of the bending part 23 can be accurately controlled.

[0050] Step S40, based on the first moving distance reaching the first preset distance, the bending part 23 can be controlled to move towards the pressing part 22 along the first direction to obtain the second moving distance of the bending part 23; through the movement in the horizontal direction, a progressive bending trajectory can be formed, enabling the connecting part 13 to be bent to the set position.

[0051] Step S50, based on the second moving distance reaching the second preset distance, the bending part 23 can be controlled to separate from the terminal 10, and the bending is completed; through staged displacement control, the bending part 23 is always kept within the set area range of the connecting part 13 during the bending process, avoiding the distance between the bending part 23 and the core wire crimping wing 12 becoming too large due to excessive displacement of the bending part 23, which may lead to a decrease in the flatness of the bending surface of the connecting part 13, and finally achieving precise control of the bending shape of the connecting part 13.

[0052] In this embodiment, the distance from the end of the connecting portion 13 of the terminal 10 away from the core wire crimping wing 12 of the terminal 10 to the core wire crimping wing 12 is the length of the connecting portion 13; the distance from the first contact position to the core wire crimping wing 12 is 40% - 60% of the length of the connecting portion 13. By defining that the distance from the first contact position to the core wire crimping wing 12 is within the range of 40% - 60% of the length of the connecting portion 13, sufficient space is reserved for the bending portion 23 to move, and at the same time, it can ensure that the bending portion 23 and the connecting portion 13 maintain an effective contact area, balancing the requirements of the operation space and the force stability.

[0053] In this embodiment, the first preset distance is 45% - 55% of the preset descending height of the end of the connecting portion 13 away from the core wire crimping wing 12. The downward pressing depth of the bending portion 23 will change the first contact position of the downward pressing shaft 232 on the connecting portion 13, thus affecting the crimping quality. When the first contact position is close to the end of the connecting portion 13 away from the core wire crimping wing 12, the bent shape of the crimping will undergo irregular deformation, resulting in poor bending quality. To avoid the above situation, by setting the first preset distance to 45% - 55% of the preset descending height, it can be ensured that the downward pressing stroke of the bending portion 23 forms a corresponding relationship with the bending angle of the connecting portion 13. This not only avoids material damage caused by excessive downward pressing but also prevents insufficient downward pressing from affecting the bending angle accuracy. Then, through staged crimping and changing the crimping direction of the downward pressing shaft 232, the downward pressing shaft 232 is kept within a certain range in the middle of the crimping portion, thereby improving the crimping quality. Among them, the preset descending height can be calculated by multiplying the length of the connecting portion 13 by the sine value of the bending angle.

[0054] In this embodiment, step S30 may include: Based on the bending portion 23 being located at the first contact position, the bending portion 23 can be controlled to move towards the terminal 10 along the second direction at the first acceleration, and the first moving distance of the bending portion 23 is obtained. By setting the first acceleration to control the downward pressing speed of the bending portion 23, the bending portion 23 can contact the connecting portion 13 at a gradually increasing moving speed, ensuring that the angle of the connecting portion 13 bent during the downward pressing process of the bending portion 23 is uniform and ensuring that the bending process proceeds smoothly.

[0055] In this embodiment, step S40 may include: Based on the first moving distance reaching the first preset distance, the bending portion 23 can be controlled to move towards the pressing portion 22 along the first direction at the first deceleration, and the second moving distance of the bending portion 23 is obtained. By setting the first deceleration to control the horizontal moving speed of the bending portion 23, the bending portion 23 can bend the connecting portion 13 to the set position in a gradually decelerating state, ensuring that the bending angle of the connecting portion 13 remains uniform during the horizontal bending process of the bending portion 23 in the second half, avoiding risks such as material fracture or excessive bending of the connecting portion 13 caused by excessive speed, and ensuring that the linearity of the bending trajectory meets the design requirements.
