Description

Technical Field

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

[0002] By inserting pins into cables such as PD fast charging cables at designated positions, the strength and toughness of the cables can be enhanced, thereby increasing the product's lifespan. In existing technology, the cable pin process includes the following steps: first, the outer sheath of the cable is laser-cut and peeled off; then, the metal braid and bulletproof wire outside the core wire are folded back; next, the core wire is manually separated outwards, and the pin is pre-inserted into the center of the core wire; finally, pressure is applied to the pin to push it to the designated position on the cable.

[0003] However, when using the above process, the depth of manual insertion of the pins into the core wire is inconsistent. If the insertion is too high, it will misalign with the pressure holding head, causing the pressure holding head to damage the core wire. In addition, when inserting the pins, the core wires need to be separated to the outside and cannot cross, otherwise the pressure holding head will damage the core wires, affecting product quality and resulting in low production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a wire insertion pin device and process, which improves the consistency of the insertion depth of the pin in the wire, avoids damage to the core wire, and improves product quality and production efficiency.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] On the one hand, a wire insertion device is provided, comprising:

[0007] A first tooling fixture and a second tooling fixture, both of which are used to fix the wire;

[0008] The hole-expanding mechanism includes a hole-expanding drive mechanism and a hole-expanding pin, wherein the hole-expanding drive mechanism drives the hole-expanding pin to press down to form an expanded hole at one end of the wire located in the first tooling fixture;

[0009] An assembly mechanism includes an assembly drive mechanism and a pressure holding assembly. The pressure holding assembly includes a pressure holding head, which has a storage bin for receiving a pin and an outlet for discharging the pin. The assembly drive mechanism drives the pressure holding assembly to pass the pin through the enlarged hole of the wire located on the second tooling fixture to insert it into a preset position of the wire.

[0010] In some possible implementations, the pressure holding assembly further includes an adsorption assembly disposed on the pressure holding head. When the assembly drive mechanism drives the pressure holding head to move toward the second tooling fixture, the pressure holding assembly adsorbs the pin. When the assembly drive mechanism drives the pressure holding assembly to reset, the pressure holding assembly releases the pin.

[0011] In some possible implementations, both the pressure holding head and the pin are conductive components, the adsorption assembly includes an electromagnet, and when the assembly drive mechanism drives the pressure holding assembly to move toward the second tooling fixture, the electromagnet is energized, causing the pressure holding head to adsorb the pin. When the assembly drive mechanism drives the pressure holding assembly to reset, the electromagnet is de-energized, causing the pressure holding head to release the pin.

[0012] In some possible implementations, the length direction of the pins is parallel to the first direction, and a plurality of the pins are arranged in the storage bin along the second direction, the first direction being perpendicular to the second direction, and the outlet is opened along the first direction.

[0013] In some possible implementations, an automatic feeding device is also included, which is connected to the inlet of the storage bin to automatically feed the pins into the storage bin.

[0014] In some possible implementations, the pressure holding assembly further includes a sensor located on the pressure holding head, the sensor being capable of sensing the pin in the storage hopper.

[0015] In some possible implementations, it also includes:

[0016] A first driving mechanism is capable of driving the reaming mechanism to move until the reaming pin abuts the end of the wire; and / or

[0017] The second drive mechanism is capable of driving the assembly mechanism to move until the pressure holding head abuts the end of the wire.

[0018] In some possible implementations, the first tooling fixture includes:

[0019] The fixed block has a first limiting groove and a second limiting groove that are connected.

[0020] A clamping assembly is used to clamp the wire at a predetermined length position, the clamping assembly being limited to the first limiting groove, and the wire being limited to the second limiting groove;

[0021] A clamping assembly is provided on the fixing block for clamping the wire that is limited to the second limiting groove.

[0022] On the other hand, a wire insertion pin process is provided, employing the wire insertion pin device as described above, the wire insertion pin process comprising:

[0023] Fix the wire to the first tooling fixture;

[0024] The control hole-expanding drive mechanism drives the hole-expanding needle to press down on the wire on the first tooling fixture to form an expanded hole at one end of the wire;

[0025] Remove the wire from the first tooling fixture and fix it to the second tooling fixture;

[0026] The control assembly drive mechanism drives the pressure holding component to pass the pin through the enlarged hole of the wire on the second tooling fixture and insert it into the preset position of the wire;

[0027] The assembly drive mechanism is controlled to drive the pressure holding assembly to reset;

[0028] The wire is processed so that the cut of the wire is flush with the end of the pin.

[0029] In some possible implementations, the pressure-holding head is provided with an adsorption component, and when the assembly drive mechanism drives the pressure-holding component, it further includes:

[0030] When the pin passes through the enlarged hole of the wire in the second tooling fixture, the pressure holding component is controlled to adsorb the pin;

[0031] When the pin is inserted into the preset position of the wire, the pressure holding component is controlled to release the pin.

[0032] The beneficial effects of this invention are:

[0033] This invention provides a wire insertion pin device and process. A first tooling fixture and a hole-expanding mechanism work together to expand the hole in a fixed wire. Then, a second tooling fixture and an assembly mechanism work together to insert the pin through the expanded hole and into a preset position on the wire. Inserting the pin directly into the expanded hole and into the preset position eliminates the need to pre-separate the core wire outwards or insert the pin to a preset depth before inserting it into the preset position. This prevents misalignment between the pressure-holding head and the pin, thus avoiding damage to the core wire and improving product quality. The process is fully automated, stable, reduces operation time, and increases efficiency. Attached Figure Description

[0046] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0049] This embodiment provides a wire insertion pin device, such as... Figures 1-5 As shown, the assembly includes a hole-expanding mechanism 2, an assembly mechanism 3, a first tooling fixture 110, and a second tooling fixture 120. Both the first tooling fixture 110 and the second tooling fixture 120 are used to fix the wire 1000. The hole-expanding mechanism 2 includes a hole-expanding drive mechanism 21 and a hole-expanding pin 22. The hole-expanding drive mechanism 21 drives the hole-expanding pin 22 to press down to form an expanded hole at one end of the wire 1000 located in the first tooling fixture 110. The assembly mechanism 3 includes an assembly drive mechanism 31 and a pressure-holding assembly 32. The pressure-holding assembly 32 includes a pressure-holding head 321, which has a storage chamber 3211 for receiving the pin 2000 and an outlet 3212 for discharging the pin 2000. The assembly drive mechanism 31 drives the pressure-holding assembly 32 to pass the pin 2000 through the expanded hole in the wire 1000 located in the second tooling fixture 120 to insert it into a preset position on the wire 1000.

[0050] The first tooling fixture 110 and the hole-expanding mechanism 2 work together to expand the hole in the fixed wire 1000. Then, the second tooling fixture 120 and the assembly mechanism 3 work together to insert the pin 2000 into the preset position of the wire 1000. Inserting the pin 2000 directly into the expanded hole and into the preset position of the wire 1000 eliminates the need to pre-separate the core wire outwards or to insert the pin 2000 to a preset depth before inserting it into the preset position. This prevents misalignment between the pressure-holding head 321 and the pin 2000, thus avoiding damage to the core wire and improving product quality. The process is fully automated, stable, reduces operation time, and improves efficiency.

[0051] The tip of the reaming needle 22 has a guiding function to avoid damaging the core wire. Furthermore, the reaming mechanism 2 presses down to a preset depth, which can be determined by experiments, etc., to avoid damaging the core wire during the reaming process due to excessive depth.

[0052] like Figure 2 , Figure 3 and Figure 5 As shown, the pressure holding assembly 32 also includes an adsorption assembly 322 disposed on the pressure holding head 321. When the assembly drive mechanism 31 drives the pressure holding head 321 to move toward the second tooling fixture 120, the pressure holding assembly 32 adsorbs the pin 2000 and inserts the pin 2000 into the wire 1000. When the assembly drive mechanism 31 drives the pressure holding assembly 32 to reset, the pressure holding assembly 32 releases the pin 2000, ensuring that the pin 2000 remains in the wire 1000, thereby improving the reliability and accuracy of the pin 2000 insertion.

[0053] In one embodiment, both the pressure holding head 321 and the pin 2000 are conductive components. The adsorption assembly 322 includes an electromagnet. When the assembly drive mechanism 31 drives the pressure holding assembly 32 to move toward the second tooling fixture 120, the electromagnet is energized, making the pressure holding head 321 magnetic. The pressure holding head 321 magnetically adsorbs the pin 2000. When the assembly drive mechanism 31 drives the pressure holding assembly 32 to reset, the electromagnet is de-energized, making the pressure holding head 321 non-magnetic, thereby releasing the pin 2000.

[0054] In another embodiment, the adsorption component 322 is a vacuum adsorption structure, specifically including a vacuum suction head fixed on the pressure holding head 321. The vacuum suction head can vacuum adsorb the insert 2000 or release the insert 2000. The working principle of the specific vacuum adsorption structure can be referred to the prior art, and will not be described in detail here.

[0055] like Figure 3 and Figure 5As shown, the length direction of the pins 2000 is parallel to the first direction, and multiple pins 2000 are arranged along the second direction in the storage bin 3211. The first direction is perpendicular to the second direction, and the outlet 3212 is opened along the first direction. In this embodiment, the first direction is the X direction, the second direction is the Y direction, and the third direction is the Z direction. The first direction, the second direction, and the third direction are mutually perpendicular. The tip of the pin 2000 at the bottom of the storage bin 3211 is aligned with the outlet 3212. When the pin 2000 is exited from the outlet 3212, it is directly inserted into the wire 1000 for easy insertion. After the bottom pin 2000 is exited from the outlet 3212, the next pin 2000 falls to the bottom, again achieving alignment of the tip of the bottom pin 2000 with the outlet 3212. By setting the shape and arrangement of the storage bin 3211 and the outlet 3212, it is ensured that the pin 2000 can be easily exported from the outlet 3212, and the pin tip is always aligned with the outlet 3212.

[0056] The wire insertion device also includes an automatic feeding device, which is connected to the inlet of the storage bin 3211 to automatically feed the insertion pin 2000 into the storage bin 3211, thereby realizing automatic feeding of the insertion pin 2000 and improving operating efficiency.

[0057] like Figure 3 and Figure 5 As shown, the pressure holding assembly 32 also includes a sensor 323 disposed on the pressure holding head 321. The sensor 323 can sense the pins 2000 in the storage bin 3211. When there are no pins 2000 in the storage bin 3211, the sensor 323 sends a signal to stop the insertion of the pins 2000, preventing the wire 1000 from missing the pins 2000. Specifically, the sensor 323 can be any commonly used detection sensor 8 in the prior art, and is not limited to any particular sensor.

[0058] like Figure 1 As shown, the wire insertion device also includes a control component 6. The control component 6 is communicatively connected to the hole-expanding mechanism 2, the assembly mechanism 3, and the sensor 323. When the sensor 323 detects that there is no insertion pin 2000 in the storage bin 3211, it sends a feedback signal to the control component 6. The control component 6 then controls the assembly mechanism 3 to operate the insertion pin 2000 according to the feedback signal. The control component 6 adopts a control structure found in the prior art, which will not be described in detail here.

[0059] like Figures 1-3As shown, the wire insertion device also includes a second drive mechanism 5. An assembly mechanism 3 is connected to the output end of the second drive mechanism 5. The second drive mechanism 5 can drive the assembly mechanism 3 to move until the pressure-holding head 321 abuts against the end of the wire 1000. When inserting the insertion pin 2000, firstly, the second drive mechanism 5 drives the assembly mechanism 3 to move, causing the pressure-holding head 321 to abut against the end of the wire 1000. Then, the assembly drive mechanism 31 drives the pressure-holding head 321 to move towards the wire 1000 to insert the insertion pin 2000 into a preset position on the wire 1000. By ensuring the distance the assembly drive mechanism 31 drives the pressure-holding head 321 to move, the insertion depth of the insertion pin 2000 is ensured to be consistent.

[0060] In one embodiment, the assembly drive mechanism 31 is a cylinder, and the pressure holding head 321 is connected to the output end of the cylinder. The second drive mechanism 5 includes a slide cylinder 51 and a connecting seat 52 connected to the output end of the slide cylinder 51. The assembly mechanism 3 is connected to the connecting seat 52. Further, the connecting seat 52 is also provided with a sliding groove 521, which allows the assembly drive mechanism 31 to drive the pressure holding head 321 to move along the sliding groove 521, improving the movement accuracy of the pressure holding head 321. In other embodiments, the assembly drive mechanism 31 and the second drive mechanism 5 can also be other linear drive structures, without limitation.

[0061] Similarly, such as Figure 1 and Figure 2 As shown, the wire insertion device also includes a first driving mechanism 4, and a hole-expanding mechanism 2 is connected to the output end of the first driving mechanism 4. The first driving mechanism 4 can drive the hole-expanding mechanism 2 to move until the hole-expanding pin 22 abuts against the end of the wire 1000. During hole expansion, the first driving mechanism 4 first drives the hole-expanding mechanism 2 to move, so that the hole-expanding pin 22 abuts against the end of the wire 1000. Then, the hole-expanding driving mechanism 21 drives the hole-expanding pin 22 to move toward the wire 1000 to expand the hole. By ensuring the distance that the hole-expanding driving mechanism 21 drives the hole-expanding pin 22 to move, the consistency of the hole-expanding depth is ensured, and the excessive hole-expanding depth is prevented from damaging the core wire.

[0062] In one embodiment, the reaming drive mechanism 21 is a cylinder, and the reaming needle 22 is connected to the output end of the cylinder via a connecting post 23. Optionally, the first drive mechanism 4 adopts the same structure as the second drive mechanism 5, including a slide cylinder 51 and a connecting seat 52 connected to the output end of the slide cylinder 51, with the reaming mechanism 2 connected to the connecting seat 52. In other embodiments, the reaming drive mechanism 21 and the first drive mechanism 4 can also be other linear drive structures, without limitation.

[0063] like Figure 3 and Figure 4As shown, the front end of the connecting seat 52 is further provided with a guide post 53. The first tooling fixture 110 and the second tooling fixture 120 are both provided with guide holes 113. When the slide cylinder 51 drives the connecting seat 52 to move, it drives the guide post 53 to move. The guide post 53 can move along the guide hole 113, which further improves the moving accuracy of the pressure holding head 321.

[0064] like Figure 1 and Figure 2 As shown, the first tooling fixture 110 and the second tooling fixture 120 are both mounted on the mounting platform 10. The two tooling fixtures are arranged along the third direction. The mounting platform 10 is equipped with a buffer 101, and the connecting seat 52 is provided with a stop 54. When the slide cylinder 51 drives the connecting seat 52 and the assembly mechanism 3 or the reaming mechanism 2 on the connecting seat 52 to move toward the tooling fixture, the buffer 101 and the stop 54 come into contact to play a buffering role, preventing the pressure holding head 321 or the reaming needle 22 from colliding with the tooling fixture and the wire 1000 on it.

[0065] like Figure 2 As shown, the connecting seat 52 is further provided with a sensor 8, and the mounting table 10 is provided with a stop bar 9. When the distance between the sensor 8 and the stop bar 9 reaches a preset condition, for example, when the sensor 8 is a photoelectric sensor 8, when the photoelectric sensor 8 senses the stop bar 9, the photoelectric sensor 8 sends a signal, and the slide cylinder 51 stops moving, ensuring the accuracy of the movement distance of the slide cylinder 51.

[0066] like Figure 1 , Figure 2 and Figure 4As shown, the first tooling fixture 110 and the second tooling fixture 120 have the same structure. The first tooling fixture 110 will be used as an example for illustrative purposes. The first tooling fixture 110 includes a fixing block 11, a clamping assembly 12, and a clamping assembly 13. The fixing block 11 has a communicating first limiting groove 111 and a second limiting groove 112. The clamping assembly 12 is used to clamp the wire 1000 at a preset length position. The clamping assembly 12 is limited to the first limiting groove 111, and the wire 1000 is limited to the second limiting groove 112. The clamping assembly 13 is disposed on the fixing block 11 and is used to clamp the wire 1000 limited to the second limiting groove 112. First, the wire 1000 is clamped and fixed at a preset position using the clamping assembly 12. Then, the clamping assembly 12 and the wire 1000 are installed on the fixing block 11, with the clamping assembly 12 confined to the first limiting groove 111 and the wire 1000 confined to the second limiting groove 112. Finally, the clamping assembly 13 clamps the wire 1000, ensuring that the wire 1000 is fixed on the fixing seat. Because the clamping assembly 12 clamps the wire 1000 at a preset length position, it ensures that the wire 1000 is fixed relative to the fixing seat at the preset position, guaranteeing consistent hole depth and subsequent pin 2000 insertion depth. Specifically, guide holes 113 are formed on the fixing block 11. Two guide holes 113 and two guide posts 53 are provided, improving the guiding reliability of the guide holes 113 and guide posts 53, and further ensuring the moving accuracy of the pressure holding head 321. The clamping assembly 12 and the clamping assembly 13 can both use existing structures and will not be described in detail.

[0067] like Figure 1 As shown, optionally, the wire insertion device also includes a frame 7, which includes a mounting platform 71 and a support frame 72. The control component 6, mounting table 10, first drive mechanism 4, and second drive mechanism 5 are fixed on the mounting platform 71. Two tooling fixtures are mounted on the mounting platform 71 via the mounting table 10. The hole-expanding mechanism 2 is connected to the mounting platform 71 via the first drive mechanism 4, and the assembly mechanism 3 is connected to the mounting platform 71 via the second drive mechanism 5. Further, the mounting platform 71 is mounted at an angle on the support frame 72, so that the hole-expanding pin 22, the insertion pin 2000, and the wire 1000 are all set at an angle. The outlet 3212 is tilted above the wire 1000, and the insertion pin 2000 can slide down to the outlet 3212 by gravity, avoiding the application of additional power to the insertion pin 2000, simplifying the structure, and reducing costs.

[0068] This embodiment also provides a wire insertion pin process, employing the wire insertion pin device as described above, such as... Figure 6 As shown, the wire connector process includes:

[0069] S100, Fix wire 1000 to the first tooling fixture 110;

[0070] S200, the control hole-expanding drive mechanism 21 drives the hole-expanding pin 22 to press down on the wire 1000 on the first tooling fixture 110 to form an expanded hole at one end of the wire 1000;

[0071] S300: Remove the wire 1000 from the first tooling fixture 110 and fix it to the second tooling fixture 120;

[0072] S400, the control assembly drive mechanism 31 drives the pressure holding assembly 32 to pass the pin 2000 through the enlarged hole of the wire on the second tooling fixture 120 and insert it into the preset position of the wire 1000.

[0073] S500, control assembly drive mechanism 31 to drive pressure holding component 32 to reset;

[0074] S600, process wire 1000 so that the cut of wire 1000 is flush with the end of pin 2000.

[0075] Compared to existing technologies, the pin 2000 is inserted into the wire 1000 first, and then the wire 1000 is processed. This greatly reduces the risk of damaging the core wire during the process, making the process simpler and significantly lowering the standards required for operation. The processing method for the wire 1000 is the same as that of existing technologies and will not be elaborated further.

[0076] Furthermore, the pressure-holding head 321 is provided with an adsorption component 322, and in step S400, it further includes:

[0077] S401, when the pin 2000 passes through the enlarged hole of the second tooling fixture 120, the pressure holding assembly 32 holds the pin 2000.

[0078] S402 When the pin 2000 is inserted into the preset position of the wire 1000, the pressure holding component 32 is controlled to release the pin 2000, which improves the reliability and accuracy of the insertion of the pin 2000.

[0079] Furthermore, taking the assembly mechanism 3 connected to the slide cylinder 51, the storage bin 3211 containing a row of pins 2000, and the adsorption component 322 being electromagnetic adsorption as an example, the process steps of the assembly mechanism 3 in step 400 are illustrated by way of example.

[0080] S4001, the slide cylinder 51 is actuated, causing the assembly mechanism 3 to move downward as a whole until the outlet 3212 of the pressure holding head 321 contacts the wire 1000 and stops.

[0081] S4011. Control the electromagnet to be energized so that the pressure holding head 321 becomes magnetic. The pressure holding head 321 attracts the pin 2000. The assembly drive mechanism 31 inserts the pin 2000 into the wire 1000.

[0082] S4021 After the pin 2000 is inserted into the designated position, the control electromagnet is de-energized, the pressure holding head 321 loses its magnetism, the pressure holding head 321 is released from the pin 2000, and then the control assembly drive mechanism 31 drives the pressure holding head 321 to return to the starting position.

[0083] When the pressure holding head 321 returns to the starting position, the electromagnet is immediately energized and becomes magnetic. At the same time, a pin 2000 will fall into the storage bin 3211 and be attracted by the pressure holding head 321. The above movement is repeated until the pin 2000 in the storage bin 3211 is exhausted.

[0084] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
