Description

Technical Field

[0001] This invention relates to the field of wire processing technology, and in particular to a wire assembly process and wire assembly equipment. Background Technology

[0002] Currently, in the connector manufacturing process, metal pins are inserted into the wire to enhance the strength of the connection between the wire and the connectors at both ends.

[0003] In existing technology, the process of installing metal pins on wires is as follows: First, the outer sheath of the wire is cut and peeled off using a laser; second, the metal braid and bulletproof wire outside the core wire are folded back; third, the core wire is manually bent outwards, and the metal pin is pre-inserted into the center of the core wire; fourth, a pressure head presses the metal pin into the required position. However, after the core wire is bent outwards, the core wires cannot cross, as crossing will cause the pressure head to damage the core wires, resulting in poor product processing.

[0004] Therefore, there is an urgent need for a wire assembly process and wire assembly equipment to solve the aforementioned problems. Summary of the Invention

[0005] Based on the above, the purpose of this invention is to provide a wire assembly process and wire assembly equipment that eliminates the need to pry the core wires apart when pushing the reinforcing pins, thereby preventing core wire crossing and improving product yield.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] On one hand, a wire assembly process is provided, wherein the wire includes a core wire and an outer sheath covering the outside of the core wire, and a central hole is provided in the middle of the core wire. The wire assembly process includes the following steps:

[0008] S1. Pre-insert the first end of the reinforcing pin into the central hole;

[0009] S2. Push the second end of the reinforcing pin so that the second end of the reinforcing pin is flush with the end face of the outer cover;

[0010] S3. Peel off the outer cover of the first preset length;

[0011] S4. Determine whether the outer sheath has been peeled off to the target length. If yes, proceed to S6; otherwise, proceed to S5.

[0012] S5. Continue to push the second end of the reinforcing pin so that the second end of the reinforcing pin is flush with the end face of the outer cover, and proceed with S3;

[0013] S6. Continue to push the second end of the reinforcing pin so that the reinforcing pin is installed in the first preset position of the center hole.

[0014] As a preferred technical solution for wire assembly process, the first preset length is not greater than half the length of the reinforcing pin.

[0015] As a preferred technical solution for wire assembly process, in step S2, a first pressure-holding head is used to push against the second end of the reinforcing pin, and the diameter of the end face of the first pressure-holding head facing the reinforcing pin is larger than the diameter of the reinforcing pin.

[0016] As a preferred technical solution for wire assembly process, in step S5, a second pressure-holding head is used to push against the second end of the reinforcing pin, and the diameter of the end face of the second pressure-holding head facing the reinforcing pin is equal to the diameter of the reinforcing pin.

[0017] As a preferred technical solution for wire assembly process, the second pressure holding head is provided with a first pushing part at one end facing the reinforcing pin. The first pushing part is conical, and the small end of the first pushing part pushes against the second end of the reinforcing pin.

[0018] As a preferred technical solution for wire assembly process, in step S6, a third pressure holding head is used to push the second end of the reinforcing pin. The third pressure holding head has a second pushing part at one end facing the reinforcing pin. The second pushing part includes a conical section and a cylindrical section. One end of the cylindrical section is connected to the small end of the conical section, and the other end pushes the second end of the reinforcing pin. The diameter of the cylindrical section is smaller than the diameter of the central hole.

[0019] As a preferred technical solution for wire assembly process, the target length is an integer multiple of the strand pitch of the core wire.

[0020] On the other hand, a wire assembly apparatus is provided, applied to the wire assembly process described in any of the above claims, the wire assembly apparatus comprising:

[0021] Fixing plate;

[0022] A fixing component is mounted on the fixing plate, the fixing component is used to fix the wire, and the first end of the reinforcing pin is inserted into the center hole of the wire;

[0023] A first driving member is mounted on the fixed plate. The output end of the first driving member is connected to a pressure holding head. The pressure holding head is coaxially arranged with the reinforcing pin. The first driving member is used to move the pressure holding head along a first direction so that the pressure holding head pushes against the second end of the reinforcing pin.

[0024] As a preferred technical solution for wire assembly equipment, it further includes a slide rail, a slide base, and a connecting plate. The slide rail is disposed on the fixed plate and extends along a first direction. The slide base is slidably connected to the slide rail. The connecting plate is connected to the slide base.

The first driving component is a cylinder, and the output end of the cylinder is connected to the connecting plate or the slide. When the cylinder drives the pressure holding head to move to the second preset position, the slide and / or the connecting plate abut against the limiting block.

[0026] The beneficial effects of this invention are as follows:

[0027] This invention provides a wire assembly process and a wire assembly device. The wire assembly process includes: S1, pre-inserting the first end of a reinforcing pin into a central hole; S2, pushing the second end of the reinforcing pin so that the second end of the reinforcing pin is flush with the end face of the outer sheath; S3, peeling off the outer sheath for a first preset length; S4, determining whether the outer sheath has been peeled to the target length. If yes, proceed to S6; if no, proceed to S5; S5, continuing to push the second end of the reinforcing pin so that the second end of the reinforcing pin is flush with the end face of the outer sheath, and proceeding to S3; S6, continuing to push the second end of the reinforcing pin so that the reinforcing pin is installed in the first preset position of the central hole. Compared to existing wire-mounting pin processes, this invention eliminates the need to pry the core wire outwards when pushing the reinforcing pin, thus preventing core wire crossing and significantly reducing the risk of damaging the core wire during wire assembly. Furthermore, the assembly method is simpler, greatly reducing operational requirements and improving product yield. Additionally, using the wire as a guide rail when pushing the reinforcing pin greatly reduces the risk of damaging the core wire during the pressure-holding process.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0043] like Figure 1 and Figure 2 As shown, this embodiment provides a wire assembly process, which includes the following steps:

[0044] S1. Insert the first end of the reinforcing pin 20 into the center hole;

[0045] S2. Push the second end of the reinforcing needle 20 so that the second end of the reinforcing needle 20 is flush with the end face of the outer sheath 102;

[0046] S3. Peel off the outer sheath 102 of the first preset length;

[0047] S4. Determine whether the outer sheath 102 has been peeled off to the target length. If yes, proceed to S6; otherwise, proceed to S5.

[0048] S5. Continue to push the second end of the reinforcing needle 20 so that the second end of the reinforcing needle 20 is flush with the end face of the outer cover 102, and proceed to S3.

[0049] S6. Continue to push the second end of the reinforcing pin 20 so that the reinforcing pin 20 is installed in the first preset position of the center hole.

[0050] Compared to existing processes for installing metal pins on wire 10, this invention eliminates the need to pry the core wire 101 outwards when pushing the reinforcing pin 20, thus preventing the core wires 101 from crossing and greatly reducing the risk of damaging the core wires 101 during assembly. Furthermore, the assembly method is simpler, significantly lowering operational standards and improving product yield. Moreover, using wire 10 as a guide rail when pushing the reinforcing pin 20 greatly reduces the risk of damaging the core wires 101 during the pressure-holding process. Finally, this wire assembly process can be fully automated, offering good stability, reduced processing time, and increased efficiency. In this embodiment, the reinforcing pin 20 is a metal pin.

[0051] It should be noted that in step S3, the first preset length can be adaptively changed according to requirements each time the outer sheath 102 is peeled off. For example, during the last peeling of the outer sheath 102, the first preset length is added to the length of the already peeled outer sheath 102 to equal the target length.

[0052] Preferably, the first preset length is no more than half the length of the reinforcing needle 20, ensuring that at least half of the reinforcing needle 20 is located inside the outer sheath 102, improving the connection stability between the reinforcing needle 20 and the core wire 101, preventing the reinforcing needle 20 from falling off, and improving the positional accuracy of the reinforcing needle 20 relative to the core wire 101, preventing the second end of the reinforcing needle 20 from being misaligned with the pressure holding head 14.

[0053] In this embodiment, the target length is an integer multiple of the twist pitch of the core wire 101 to meet production requirements. In this embodiment, the number of times step S3 is repeated is N, the length of the reinforcing needle 20 is A, and the twist pitch of the core wire 101 is B. When the target length is D times the twist pitch, where 2*B / A is rounded down to C, and N≥D*(C+1), therefore, the first preset length can be D*B / N.

[0054] In this embodiment, as Figure 3 As shown, the reinforcing pin 20 is 13.7 mm long and 0.5 mm in diameter, and the target length of the outer sheath 102 of the wire 10 that needs to be cut is 11 mm. Therefore, step S3 is repeated twice, cutting 5.5 mm each time to prevent the reinforcing pin 20 from falling off.

[0055] In step S2, a first pressure-holding head is used to push against the second end of the reinforcing pin 20. The diameter of the end face of the first pressure-holding head facing the reinforcing pin 20 is larger than the diameter of the reinforcing pin 20, thereby increasing the contact area between the first pressure-holding head and the reinforcing pin 20 and preventing misalignment between the reinforcing pin 20 and the first pressure-holding head. In this embodiment, the diameter of the first pressure-holding head is the same as the diameter of the wire 10.

[0056] Preferably, such as Figure 2 and Figure 4As shown, in step S5, the second pressure head 30 is used to push against the second end of the reinforcing pin 20. Along the path of pushing against the reinforcing pin 20, the outer sheath 102 is stripped off, but the original state of the core wire 101 of the wire 10 remains unchanged. In order to prevent the second pressure head 30 from damaging the core wire 101, and in order to increase the diameter of the reinforcing pin 20 as much as possible, the diameter of the end face of the second pressure head 30 facing the reinforcing pin 20 is equal to the diameter of the reinforcing pin 20.

[0057] More preferably, the second pressure holding head 30 is provided with a first pushing part at one end facing the reinforcing needle 20. The first pushing part is conical, and the small end of the first pushing part pushes against the second end of the reinforcing needle 20. When the second pressure holding head 30 pushes against the reinforcing needle 20, the core wire 101 can spread outward under the guidance of the conical surface of the first pushing part, preventing the core wire 101 from stacking and causing damage to the core wire 101.

[0058] Preferably, such as Figure 2 and Figure 5 As shown, in step S6, a third pressure-holding head 40 pushes against the second end of the reinforcing pin 20. The third pressure-holding head 40 has a second pushing portion at one end facing the reinforcing pin 20. The second pushing portion includes a tapered section 401 and a cylindrical section 402. One end of the cylindrical section 402 is connected to the small end of the tapered section 401, and the other end pushes against the second end of the reinforcing pin 20. The diameter of the cylindrical section 402 is smaller than the diameter of the central hole. The first preset position of the reinforcing pin 20 is lower than the end face of the outer sheath 102. The cylindrical section 402 needs to extend into the central hole covered by the outer sheath 102 to install the reinforcing pin 20 to the first preset position. In this embodiment, the diameter of the cylindrical section 402 is smaller than the diameter of the central hole, i.e., smaller than the diameter of the reinforcing pin 20, to prevent the third pressure-holding head 40 from damaging the root of the core wire 101. Furthermore, when the third pressure-holding head 40 pushes against the reinforcing pin 20, the core wire 101 can spread outward under the guidance of the conical surface of the conical section 401, preventing the core wire 101 from stacking and causing damage to the core wire 101.

[0059] like Figure 6 and Figure 7 As shown, this embodiment also provides a wire assembly device 1, which is applied to the above-mentioned wire assembly process. The wire assembly device 1 includes a fixing plate 11, a fixing component 12, and a first driving component 13.

[0060] Specifically, the fixing component 12 is mounted on the fixing plate 11 and is used to fix the wire 10. The first end of the reinforcing pin 20 is inserted into the center hole of the wire 10. The first driving component 13 is mounted on the fixing plate 11, and the output end of the first driving component 13 is connected to a pressure holding head 14. The pressure holding head 14 is coaxially arranged with the reinforcing pin 20. The first driving component 13 is used to move the pressure holding head 14 along a first direction so that the pressure holding head 14 pushes against the second end of the reinforcing pin 20. During the processing of the wire 10, the wire 10 can be mounted on the fixing component 12, and then the first driving component 13 drives the pressure holding head 14 to push against the reinforcing pin 20, thereby assembling the reinforcing pin 20. This wire assembly equipment 1 achieves automation, good stability, reduces operation time, and improves efficiency.

[0061] It should be noted that the fixing component 12 is existing technology, and the specific structure and working principle of the fixing component 12 will not be described in detail here.

[0062] Preferably, the wire assembly equipment 1 further includes a slide rail 15, a slide block 16, and a connecting plate 17. The slide rail 15 is disposed on the fixed plate 11 and extends along a first direction. The slide block 16 is slidably connected to the slide rail 15. The connecting plate 17 is connected to the slide block 16. The pressure holding head 14 is mounted on the connecting plate 17. The connecting plate 17 and / or the slide block 16 are connected to the output end of the first driving member 13. The first driving member 13 can drive the connecting plate 17, the slide block 16, and the pressure holding head 14 to move along the first direction. The slide rail 15 improves the movement accuracy of the pressure holding head 14.

[0063] More preferably, the fixing component 12 and the pressure holding head 14 are two sets and correspond one to one. The two pressure holding heads 14 are installed on both sides of the connecting plate 17. The first driving component 13 can drive the two pressure holding heads 14 to move along the first direction at the same time, so as to realize the simultaneous processing of the two wires 10 and improve the work efficiency.

[0064] Furthermore, the wire assembly equipment 1 also includes a limiting block 18, which is mounted on the fixed plate 11. The first driving component 13 is a cylinder, and the output end of the cylinder is connected to the connecting plate 17 or the slide 16. When the cylinder drives the pressure holding head 14 to move to the second preset position, the slide 16 and / or the connecting plate 17 abut against the limiting block 18 to ensure that the movement stroke of the pressure holding head 14 meets the requirements.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
