Description

Technical Field

[0001] The utility model relates to the technical field of line plugging, in particular to a line-connecting device. Background Art

[0002] Wire-type elastic plugs (commonly known as twisted needles) are made of two layers of multi-strand copper wires twisted in opposite directions, welded at both ends into a bundle, one end pressed into a sleeve, and the other end upset and raised. They are characterized by light weight, small size, and reliable contact. They are widely used in electronic components. During the production process of wire-type elastic plugs, the wire body needs to be inserted into the inside of the needle sleeve and fixed inside the needle sleeve.

The wire harness guide is fixed on the wire harness placement table and fits with the crimping mechanism. In actual use, the wire harness to be processed is manually fed into the other side of the crimping mechanism through the manual threading mechanism. The wire harness guide can guide the wire harness to smoothly pass through the crimping mechanism to avoid wire harness bifurcation. The needle sleeve feeding mechanism feeds the needle sleeve into the crimping mechanism from the other side to realize the plugging of the wire body.

[0037] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] In order to solve the technical problem in the prior art that the threading and plugging process of the wire body with the needle sleeve are mainly performed manually, resulting in low threading efficiency of the wire body, the utility model provides a threading device for being arranged on a wire body plugging device, the wire body plugging device is used to plug the plugging end of the wire body into the needle sleeve 10a, the wire body includes a wire core and an insulating skin wrapped around the wire core, and the threading device is arranged on the wire body plugging device to realize automatic threading, skin cutting and plugging of the wire body plugging device, thereby reducing the manpower required for wire body plugging and improving the wire body plugging efficiency.

[0039] like Figure 1-2As shown, the wire plugging device of this embodiment includes a frame 10, a plug-in unit 20, a wire-up device 40, a wire-down unit 50, a material-discharging unit 70, a grabbing unit 80 and a transfer unit 90. The plug-in unit 20 is fixed to the frame 10. The plug-in unit 20 is provided with a plug-in cavity 21, and the plug-in cavity 21 is provided for fixing the needle sleeve 10a; the wire-cutting unit 44 is located on one side of the plug-in unit 20 and is used to cut off the insulation skin of the wire plug-in end; the wire-up device 40 is located on the side of the plug-in unit 20 close to the skin-cutting unit and is used to clamp the wire body and can be inserted into the plug-in cavity 21. The movement in the direction makes the plug-in end of the clamped wire body plug into the needle sleeve 10a of the plug-in cavity 21; the unloading unit 50 is located on the other side of the plug-in unit 20 and is slidably connected to the frame 10, and is used to pull out the wire body after the plug-in needle sleeve 10a away from the plug-in unit 20, the unloading unit 70 is used to unload the needle sleeve 10a, and the grabbing unit 80 is provided at the discharge end of the unloading unit 70, and is used to grab a single needle sleeve 10a unloaded to the discharge end, and the transfer unit 90 is used to grab the needle sleeve 10a of the grabbing unit 80 and transfer the grabbed needle sleeve 10a to the plug-in cavity 21.

[0040] Specifically, when the wire body is being plugged in, the unloading unit 70 unloads the needle sleeve 10a toward the discharge end, the grabbing unit 80 grabs the single needle sleeve 10a unloaded to the discharge end, the transfer unit 90 grabs the needle sleeve 10a grabbed by the grabbing unit 80, and transfers the grabbed needle sleeve 10a to the plug-in cavity 21, the wire body is clamped by the thread-on device 40, and then the insulation skin of the plug-in end of the broken wire body is stripped off. After the insulation skin of the plug-in end is stripped off, the thread-on device 40 moves toward the plug-in cavity 21, and the clamped wire body is plugged into the needle sleeve 10a of the plug-in cavity 21 through the plug-in end, thereby completing the plug-in of the wire body.

[0041] like Figure 1-5 As shown, the thread-up device 40 of this embodiment includes a sliding seat 41, a clamping module 42, a stripping drive module 43 and a wire cutting unit 44. The sliding seat 41 is connected to the frame 10, and the stripping drive module 43 is connected to the sliding seat 41 for driving the sliding seat 41 to slide along the frame 10. The clamping module 42 is installed on the sliding seat 41 for clamping the wire body. The wire cutting unit 44 is located on the side of the sliding seat 41 close to the plug-in unit 20 for cutting off the insulation skin of the plug-in end of the wire body.

[0042] Specifically, the sliding seat 41, the clamping module 42, the plugging and stripping drive module 43 and the cutting unit 44, the sliding seat 41 can be slidably connected to the frame 10, the clamping module 42 is installed on the sliding seat 41, and can be moved by sliding the sliding seat 41, the clamping module 42 can clamp the wire body, and the plugging and stripping drive module 43 can drive the sliding seat 41 to drive the wire body clamped by the clamping module 42 to move toward or away from the plug-in cavity 21. Through this arrangement, when the wire body is plugged in, the clamping module 42 clamps the wire body, The plug-in and stripping drive module 43 drives the sliding seat 41 to move toward the plug-in cavity 21, and then cuts off the insulation skin of the plug-in end of the wire body through the wire cutting unit 44, and then strips off the insulation skin of the plug-in end of the wire body. After the insulation skin of the plug-in end is stripped, the plug-in and stripping drive module 43 drives the plug-in end of the wire body into the plug-in cavity 21, and finally realizes automatic plug-in with the needle sleeve 10a of the plug-in cavity 21, and realizes automatic plug-in with the needle sleeve of the plug-in cavity, and finally realizes automatic threading of the wire body and automatic plug-in of the wire body and the needle sleeve, reducing the manpower required for wire body plug-in and improving the wire body plug-in efficiency.

[0043] It can be understood that the clamping module 42 can be a clamping cylinder or two clamping members arranged opposite to each other.

[0044] In this embodiment, the sliding seat 41 is slidably connected to the frame 10 in a direction approaching or moving away from the inserting cavity 21 .

[0045] In this embodiment, Figure 1-5 As shown, the clamping module 42 includes a limiting base 421, a clamping block 422 and a clamping driver 423. The limiting base 421 is fixed to the sliding base 41, the clamping block 422 is arranged opposite to the limiting base 421, and the clamping driver 423 is installed on the limiting base 421 and connected to the clamping block 422, and is used to drive the clamping block 422 to slide toward or away from the limiting base 421.

[0046] Specifically, during the wire clamping process, the wire to be clamped passes between the limiting base 421 and the clamping block 422, and the clamping driver 423 drives the clamping block 422 to move toward the limiting base 421 to limit the wire, thereby achieving wire clamping.

[0047] In this embodiment, a wire cavity for accommodating the wire is formed between the clamping block 422 and the limiting base 421 . The wire cavity accommodates and limits the wire to prevent damage to the wire.

[0048] It is understandable that the stripping drive module 43 can be any drive component such as a cylinder, a hydraulic cylinder, etc. that can drive the sliding seat 41.

[0049] In this embodiment, Figure 3-5As shown, the stripping drive module 43 includes a stripping drive motor 431 and a screw, which is rotatably connected to the frame 10. The stripping drive motor 431 is connected to the screw to drive the screw to rotate. The sliding seat 41 is threadedly connected to the screw via a screw nut. Specifically, the first motor drives the screw to rotate, thereby driving the sliding seat 41 to slide.

[0050] In this embodiment, the screw rod extends axially toward the insertion cavity 21 .

[0051] In this embodiment, Figure 3-5 As shown, the frame 10 is provided with a first slide rail, and sliding support edges are provided on both sides of the screw nut, and the sliding support edges are slidably connected to the first slide rail. Specifically, the sliding of the sliding support edges and the first slide rail can improve the stability of the sliding seat 41 during the sliding process.

[0052] It is understandable that the wire body can be segmented before the wire body plugging device is plugged in, and then the plugging of one section of the wire body is completed before plugging in another section of the wire body, or the wire body can be cut after the plugging of the wire body plugging device is completed.

[0053] It can be understood that the wire cutting unit 44 can cut the insulation of the wire body by cutting the circumference of the wire body with a cutting knife, or cut the insulation of the wire body by cutting the two sides of the wire body with a cutting knife.

[0054] In one embodiment, Figure 1 and 3 As shown, the wire cutting unit 44 includes two laser generators 441, which are fixed to the frame 10 and emit lasers to the upper and lower sides of the wire body, thereby cutting the insulation of the wire body.

[0055] In one embodiment, Figure 3-5 As shown, the wire plugging device also includes a wire breaking unit 45, which is fixed to the frame 10 and is located on the side of the plugging unit 20 near the wire cutting unit 44, and is used to pull out the wire. Specifically, after the plug is inserted into the needle sleeve 10a by the movement of the clamping module 42, the wire pulling unit 50 pulls out the wire, and after pulling it out a certain distance, the wire is cut by the wire breaking unit 45. After the cutting is completed, the plugging of the wire segment is completed, and then the subsequent wires can be plugged in through the cycle.

[0056] In this embodiment, the wire body is wound on the material rack, and during the splicing operation, it is unloaded through the material rack to the guide wheel rack 49.

[0057] It can be understood that the wire cutting unit 45 can be a cutter and a cutter driving member, and the cutter driving member drives the cutter to move toward the cutter seat, thereby cutting the wire.

[0058] In one embodiment, Figure 3-6 As shown, the wire breaking unit 45 includes a wire breaking drive 451 and two wire cutting knives 452. The two wire cutting knives 452 are arranged opposite to each other. The two wire cutting knives 452 can cut the wire body by approaching each other, or enter the cutting position of the insulation cut by the cutting unit 44 by approaching each other, so that the wire cutting knives 452 can move to peel off the insulation cut by the cutting unit 44 from the wire core. The wire breaking drive 451 is connected to the two wire cutting knives 452 and is used to drive the two wire cutting knives 452 to approach or move away from each other.

[0059] Specifically, through this arrangement, the wire breaking unit 45 can have two functions: cutting the wire body and cooperating with the clamping module 42 to strip the cut insulation. On the one hand, when cutting the wire body, the wire breaking drive 451 drives the two wire cutting knives 452 to approach each other and directly cut the wire body. On the other hand, when the wire body is plugged in and the lower line unit 50 pulls the plugged wire body out a distance, the wire breaking drive 451 drives the two wire cutting knives 452 to approach each other, so that the two wire cutting knives 452 enter the cutting position of the insulation. After the wire cutting knives 452 enter the cutting position of the insulation, the clamping module 42 moves away from the plug-in cavity 21. The wire cutting knife 452 blocks the insulation, so that the two wire cutting knives 452 will drive the cut insulation to be stripped from the wire core, and finally realize the automatic stripping of the insulation.

[0060] In this embodiment, Figure 6 As shown, the two wire cutting knives 452 are provided with intersecting shearing bevels 4521 on the opposite sides thereof, so that the two wire cutting knives 452 can shear the wire body by approaching each other. Specifically, by setting the shearing bevels 4521 of the wire cutting knives 452, the wire cutting knives 452 can shear the wire body by approaching each other, thereby facilitating the cutting of the wire body.

[0061] In this embodiment, Figure 6 As shown, the shearing bevel 4521 is provided with a plurality of spaced-apart receiving grooves 4522 for receiving the wire. Specifically, as the wire is cut by the two wire cutting knives 452, the two sides of the cut wire will enter the receiving grooves 4522 of the two wire cutting knives 452 and be received by the receiving grooves 4522, thereby preventing the wire cutting knives 452 from squeezing the wire and causing deformation of the wire.

[0062] In one embodiment, the wire cutting drive member 451 includes a double-ended clamping cylinder, and the two wire cutting knives 452 are respectively fixed to the two driving ends of the double-ended clamping cylinder. Specifically, the double-ended clamping cylinder can drive the two wire cutting knives 452 to move closer to each other by driving the two driving ends closer to each other.

[0063] In one embodiment, Figure 3-6As shown, the wire cutting unit 45 further includes a wire cutting adjustment cylinder 453, which is fixed to the frame 10. The wire cutting drive member 451 is mounted on the wire cutting adjustment cylinder 453 and can be moved by the drive of the wire cutting adjustment cylinder 453. Specifically, the wire cutting adjustment cylinder 453 drives the wire cutting drive member 451 to move, thereby adjusting the positions of the two wire cutting knives 452, thereby facilitating wire cutting.

[0064] In this embodiment, Figure 3-5 As shown, the online device 40 also includes a first proximity switch 46, a second proximity switch 47 and a third proximity switch 48. The first proximity switch 46, the second proximity switch 47 and the third proximity switch 48 are fixed to the frame 10 and are located on one side of the sliding seat 41 and are spaced in sequence toward the direction of the wire breaking unit 45. The sliding seat 41 is provided with a sensing element. The first proximity switch 46 is electrically connected to the laser generator 441 and the insertion and stripping drive motor 431, the second proximity switch 47 is electrically connected to the wire breaking drive element 451, and the third proximity switch 48 is electrically connected to the insertion and stripping drive motor 431. Specifically, when the sliding seat 41 is driven by the plug-in stripping drive motor 431 to slide toward the plug-in cavity 21, when the first proximity switch 46 senses the approach of the sensing element, the plug-in stripping drive motor 431 stops running, the laser generator 441 starts, and the insulation skin of the plug-in end of the wire body is cut off by forming a laser. After the insulation skin is cut, the plug-in stripping drive motor 431 drives the sliding seat 41 to continue sliding toward the plug-in cavity 21. When the second proximity switch 47 senses the approach of the sensing element, the plug-in stripping drive motor 431 stops, and the wire-breaking drive member 451 drives the two wire-breaking knives 452 to approach each other, so that the two wire-breaking knives 452 enter the insulation skin. At the cutting point, after the wire cutting knife 452 enters the cutting point of the insulation, the stripping drive motor 431 drives the sliding seat 41 to move away from the plug-in cavity 21 until the first proximity switch 46 senses the approach of the sensing part again, and the stripping drive motor 431 stops. At this time, the two wire cutting knives 452 will drive the cut insulation to be stripped from the wire core, and then, the stripping drive motor 431 drives the sliding seat 41 to continue sliding toward the plug-in cavity 21 again until the third proximity switch 48 senses the approach of the sensing part, and the stripping drive motor 431 stops. At this time, the wire body is plugged into the needle sleeve 10a with the stripped plug-in end, and finally the plug-in of the wire body is completed.

[0065] In this embodiment, Figure 1 and 3 As shown in Figure 5-5, the thread-threading device 40 also includes a guide wheel frame 49, which is fixed to the sliding seat 41 and is equipped with two opposing rows of guide wheels. The two rows of guide wheels are used to guide the thread body. Specifically, after passing between the two rows of guide wheels, the thread body enters the clamping module 42 and is clamped by the clamping module 42. The guide wheel frame 49 can guide the thread body to prevent it from deflecting.

[0066] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the utility model is described in detail:

[0067] When performing the plug-in operation of the wire body, the blanking unit 70 discharges the needle sleeve 10a toward the discharge end, the grabbing unit 80 grabs the single needle sleeve 10a that is discharged to the discharge end, the transfer unit 90 grabs the needle sleeve 10a grabbed by the grabbing unit 80, and transfers the grabbed needle sleeve 10a to the plug-in cavity 21, and the sliding seat 41 slides toward the plug-in cavity 21 through the drive of the plug-in stripping drive motor 431. When the first proximity switch 46 senses that the sensing part is approaching, the plug-in stripping drive motor 431 stops running, and the laser generator 441 starts to cut off the insulation skin of the plug-in end of the wire body by forming a laser. After the insulation skin is cut, the plug-in stripping drive motor 431 drives the sliding seat 41 to continue sliding toward the plug-in cavity 21. When the second proximity switch 47 senses that the sensing part is approaching, the plug-in The stripping drive motor 431 stops, and the wire-breaking drive component 451 drives the two wire-breaking knives 452 to approach each other, so that the two wire-breaking knives 452 enter the cutting position of the insulation. After the wire-breaking knives 452 enter the cutting position of the insulation, the stripping drive motor 431 drives the sliding seat 41 to move away from the plug-in cavity 21 until the first proximity switch 46 again senses the approach of the sensing component, and the stripping drive motor 431 stops. At this time, the two wire-breaking knives 452 will drive the cut insulation to be stripped from the wire core, and then, the stripping drive motor 431 drives the sliding seat 41 to continue sliding toward the plug-in cavity 21 again until the third proximity switch 48 senses the approach of the sensing component, and the stripping drive motor 431 stops. At this time, the wire body is plugged into the needle sleeve 10a with the stripped plug-in end, and finally the plug-in of the wire body is completed.

[0068] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
