Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wire body plug-in technology, in particular to a plug-in device and a plug-in method. BACKGROUND

[0002] The wire body type elastic plug-in (commonly known as a twisted wire) is twisted in two layers by multiple copper wires in opposite directions, and the two ends are fused into a bundle. One end is pressed into a sleeve, and the other end is upset and protruding. It has the characteristics of light weight, small size and reliable contact, and is widely used in electronic components. In the generation process of wire body type elastic plug-in, the wire body is inserted into the inside of the needle sleeve and fixed inside the needle sleeve.

[0003] A wire harness crimping device disclosed in a patent document with publication number CN219419811U, the crimping device is provided with a base, a crimping mechanism, a needle sleeve feeding mechanism and a manual threading mechanism. The manual threading mechanism includes a wire harness guide and a wire harness fixing member. The wire harness guide is fixed on the wire harness placement table and is in contact with the crimping mechanism. In actual use, the operator sends the wire harness to be processed to the other side of the crimping mechanism through the manual threading mechanism. The wire harness guide can guide the wire harness to smoothly enter the crimping mechanism, avoiding wire harness bifurcation. The needle sleeve feeding mechanism sends the needle sleeve to the crimping mechanism from the other side, realizing the plug-in of the wire body.

[0004] Although the wire harness crimping device can realize the plug-in of the wire body, the pulling-in of the wire body before plug-in, the stripping of the wire body and the pulling-out of the wire body after plug-in all need to be done manually, resulting in low automation degree of the plug-in device, and thus consuming a large amount of manpower in the wire body plug-in process and having low plug-in efficiency, which is difficult to meet the actual production needs of wire body plug-in. SUMMARY

[0005] The present application aims to overcome the above technical deficiencies and provides a plug-in device and a plug-in method to solve the technical problem of low automation degree of the plug-in device in the prior art, resulting in a large amount of manpower consumed in the wire body plug-in process and low efficiency.

[0063] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be 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.

[0064] To address the technical problem of low automation levels in existing plugging devices, resulting in high labor consumption and low efficiency during the wire plugging process, embodiments of the present invention provide a plugging device and plugging method. The plugging device is used to plug the plugging end of a wire into a pin sleeve 10a. The wire includes a wire core and an insulating sheath wrapped around the wire core. The plugging device can automatically plug the wire into the pin sleeve 10a, thereby effectively reducing the labor required for wire plugging, improving wire plugging efficiency, and ultimately meeting wire plugging process requirements.

[0065] like Figure 1-5 As shown, the plug-in device provided by the embodiment of the present invention includes a frame 10, a plug-in unit 20, a wire cutting unit 30, a wire clamping unit 40 and a wire lowering unit 50. The plug-in unit 20 is fixed to the frame 10, and 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 30 is located on one side of the plug-in unit 20, and is used to cut off the insulation skin of the plug-in end of the wire; the wire clamping unit 40 is located on the side of the plug-in unit 20 close to the wire cutting unit 30, and is used to clamp the wire, and can be moved toward the plug-in cavity 21 so that the plug-in end of the clamped wire is plugged into the needle sleeve 10a of the plug-in cavity 21; the wire lowering 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 the wire away from the plug-in unit 20 after the pin sleeve 10a is plugged in.

[0066] Specifically, the plug-in device is provided with a frame 10, a plug-in unit 20, a tangent unit 30, a wire clamping unit 40 and a down-line unit 50. The plug-in unit 20 is fixed to the frame 10 and is provided with a plug-in cavity 21. The plug-in cavity 21 can be used to fix the needle sleeve 10a. The tangent unit 30 is located on one side of the plug-in unit 20. During the plug-in process, the insulation skin of the plug-in end of the wire to be plugged with the needle sleeve 10a can be cut off to facilitate the stripping of the insulation skin. The wire clamping unit 40 is located on one side of the plug-in unit 20 close to the tangent unit 30 and can clamp the wire. The down-line unit 50 is provided on the other side of the plug-in unit 20 and can pull out the wire after the wire is plugged in. Through the arrangement of the above structure When the wire body is plugged in, the wire body is first clamped by the wire body clamping unit 40, and the needle sleeve 10a is installed in the plug-in cavity 21 of the plug-in unit 20. Then, the insulation skin of the wire body plug-in end is cut off by the wire cutting unit 30, 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 wire body clamping unit 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 to complete the plug-in of the wire body. After the wire body is plugged in, it can be pulled out by the line-pulling unit 50, which can realize automatic plug-in of the wire body, effectively reduce the manpower required for wire body plug-in, improve the plug-in efficiency of the wire body, and thus meet the wire body plug-in process requirements.

[0067] In this embodiment, the wire body is a conductive wire.

[0068] In this embodiment, Figure 1-5 As shown, the plug-in unit 20, the wire cutting unit 30, the wire clamping unit 40 and the wire lowering unit 50 of the plug-in device are each provided with two groups, so that the plug-in device can plug in two groups of wires at the same time.

[0069] It is understandable that the frame 10 can be any frame structure that can be supported on the ground.

[0070] It can be understood that the plug-in unit 20 can be a frame or a block structure in which the plug-in cavity 21 can be set.

[0071] In one embodiment, Figure 3-5As shown in Figure 10, the plug-in unit 20 includes a plug-in frame 22, a pressing drive member 23, a pressing ring 24 and a plurality of pressure rods 25. The plug-in frame 22 is fixed to the frame 10, and the plug-in cavity 21 is arranged in the plug-in frame 22. The pressing ring 24 is rotatably connected to the plug-in frame 22 and is concentrically arranged with the plug-in cavity 21. The inner side of the pressing ring 24 is provided with a plurality of recessed portions 241 spaced apart from each other. Each pressure rod 25 is spaced apart along the circumference of the plug-in cavity 21 and is slidably connected to the plug-in frame 22. One end of the pressure rod 25 extends to the plug-in cavity 21, and the other end of the pressure rod 25 extends out of the plug-in frame 22 and abuts against the recessed portion 241 of the pressing ring 24, so that the pressing ring 24 drives each pressure rod 25 toward the plug-in cavity by rotation. The connecting cavity 21 slides, and the clamping drive 23 is connected to the clamping ring 24 to drive the clamping ring 24 to rotate. Specifically, through the above arrangement, when the wire core of the plug-in end is inserted into the needle sleeve 10a in the plug-in cavity 21, the clamping drive 23 is started, driving the clamping ring 24 to rotate. During the rotation of the clamping ring 24, the pressure rod 25 disengages from the recessed portion 241, so that the clamping ring 24 drives each pressure rod 25 to slide toward the plug-in cavity 21 through the inner side wall, and finally presses the needle sleeve 10a toward the direction of the wire core, and finally locks the wire core. Through this arrangement, the plug-in unit 20 can automatically lock the wire body after the wire body is plugged in while providing the wire body for plugging in.

[0072] In this embodiment, the pressing drive 23 is a cylinder, and a hinged wall is provided on the outside of the pressing ring 24, which is hinged to the driving end of the pressing drive 23. When the pressing drive 23 drives the driving end to move, the pressing ring 24 is driven to rotate through the hinged wall.

[0073] It can be understood that the wire cutting unit 30 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.

[0074] In one embodiment, Figure 1 and 3 As shown, the wire cutting unit 30 includes two laser generators 31 , 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.

[0075] It can be understood that the wire clamping unit 40 can be a clamping cylinder installed on the slide, or a robot equipped with a clamping head, etc., which can clamp the wire and drive the wire to move toward or away from the plug-in cavity 21.

[0076] It can be understood that the movement of the wire clamping unit 40 can be controlled manually through a driving component.

[0077] In one embodiment, Figure 1-5As shown, the wire clamping unit 40 includes a sliding seat 41, a clamping module 42 and a stripping drive module 43. The sliding seat 41 is connected to the frame 10 for sliding toward or away from the plug-in cavity 21. The stripping drive module 43 is connected to the sliding seat 41 for driving the sliding seat 41 to slide. The clamping module 42 is installed on the sliding seat 41 for clamping the wire.

[0078] Specifically, the clamping module 42 can clamp the wire body, and the 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 setting, when the wire body is plugged in, the clamping module 42 clamps the wire body, and the stripping drive module 43 drives the sliding seat 41 to move toward the plug-in cavity 21, thereby driving the plug-in end of the wire body into the plug-in cavity 21, and finally realizing automatic plug-in with the needle sleeve 10a of the plug-in cavity 21, thereby improving the plug-in efficiency of the wire body.

[0079] It is understandable that the clamping module 42 can be a clamping cylinder or two clamping members 513 arranged opposite to each other.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] In this embodiment, Figure 3-5 As shown, the insertion and stripping drive module 43 includes an insertion and stripping drive motor 431 and a screw. The screw extends axially toward the insertion cavity 21 and is rotatably connected to the frame 10. The insertion and 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.

[0085] In the embodiment, the rack 10 is provided with the first slide rail, and the slide support edges are arranged on both sides of the screw nut and are slidably connected to the first slide rail. Specifically, the stability of the sliding seat 41 during sliding can be improved by the sliding of the slide support edges and the first slide rail.

[0086] In the embodiment, as shown in Figure 1 and 3 As shown in FIG. 5, the wire clamping unit 40 includes a guide wheel frame 44 fixed to the sliding seat 41, and the guide wheel frame 44 is provided with two rows of guide wheels opposite to each other, which are used for guiding the wire. Specifically, after the wire passes between the two rows of guide wheels, the wire enters the clamping module 42 and is clamped by the clamping module 42. The guide wheel frame 44 can guide the wire to avoid deviation of the wire.

[0087] It can be understood that the wire can be segmented before being inserted into the insertion device, and then the insertion of the wire in one segment is completed, and then the insertion of the wire in another segment is performed, or the wire is cut off after the insertion device completes the insertion.

[0088] It can be understood that the wire outputting driving structure of the lower wire unit 50 can be a belt, a mechanical hand or the like connected to the insertion cavity 21.

[0089] In one of the embodiments, as shown in Figure 1 and 7 As shown in FIG. 8, the lower wire unit 50 includes a wire clamping module 51, a wire pulling driving module 52 and a wire reel 53. The wire clamping module 51 is slidably connected to the rack 10, and the wire clamping module 51 can clamp the wire after the insertion needle sleeve 10a by sliding towards the insertion cavity 21, and pull out the wire by sliding away from the insertion cavity 21. The wire reel 53 is fixed to the rack 10 and located below the wire clamping module 51, and is used for placing the pulled-out wire. The wire pulling driving module 52 is connected with the wire clamping module 51 and is used for driving the wire clamping module 51 to slide.

[0090] Specifically, the downline unit 50 is provided with a wire clamping module 51, a wire pulling drive module 52 and a wire pay-off frame 53. The wire clamping module 51 is slidably connected to the frame 10, and can clamp the wire body after the needle sleeve 10a is inserted by sliding toward the insertion cavity 21, and pull out the wire body by sliding away from the insertion cavity 21. The wire pay-off frame 53 is located below the wire clamping module 51, and the wire pulling drive module 52 can drive the wire clamping module 51. Through the above settings, when the wire end of the wire body is inserted into the needle sleeve 10a and locked with the needle sleeve 10a, the wire pulling drive module 52 drives the wire clamping module 51. After the module 51 slides toward the plug-in cavity 21 to the plug-in cavity 21, it clamps the needle sleeve 10a of the plug-in cavity 21 to clamp the wire body after plugging in, and then the wire pulling drive module 52 drives the wire clamping module 51 to slide in the direction away from the plug-in cavity 21 to pull the wire body. After all the wire bodies are led out, the wire clamping module 51 releases the clamping of the needle sleeve 10a, so that the wire body after plugging in falls onto the wire pay-off rack 53, thereby realizing automatic unloading of the wire body after plugging in, reducing the manpower required for unloading the wire body, speeding up the unloading efficiency of the wire body, and providing convenience for the subsequent plugging operation of the wire body.

[0091] It can be understood that the wire clamping module 51 can be any clamping device such as a robot arm that can clamp the wire.

[0092] In one embodiment, Figure 7-8 As shown, the wire clamping module 51 includes a base 511, a mounting frame 512 and a clamping member 513. The base 511 is slidably connected to the frame 10, the mounting frame 512 is fixed to the base 511, and the clamping member 513 is fixed to the mounting frame 512 for clamping the wire after plugging. The wire pulling drive module 52 is connected to the base 511. Specifically, the wire clamping module 51 is slidably connected to the frame 10 through the base 511, and the clamping member 513 is fixed on the base 511 through the mounting frame 512. When clamping the wire body after plugging, the wire pulling driving module 52 drives the base 511 to move to a certain position in the direction of the plug-in cavity 21, and the clamping member 513 is started to clamp the needle sleeve 10a in the plug-in cavity 21. After clamping the needle sleeve 10a, when the wire pulling driving module 52 drives the base 511 to move to a certain position in the direction away from the plug-in cavity 21, the clamping member 513 releases the clamping of the needle sleeve 10a, so that the wire body after plugging falls on the wire pay-off frame 53.

[0093] In this embodiment, Figure 9 As shown, the mounting frame 512 is provided with a straight slot 5121, and a bolt passes through the straight slot 5121 and is threadedly connected to the base 511 to fix the mounting frame 512. Specifically, the mounting frame 512 is fixed to the base 511 by the bolt, and the mounting position of the mounting frame 512 can be adjusted through the straight slot 5121, thereby adjusting the position of the clamping member 513, so that the clamping member 513 can clamp the wire more accurately.

[0094] It can be understood that the wire driving module 52 can be any driving device such as a motor screw module, a cylinder or a hydraulic cylinder that can drive the base 511 to move.

[0095] In this embodiment, Figure 7-8 As shown, the wire drawing drive module 52 includes a wire-drawing drive motor 521 and a gear 522. The frame 10 is provided with a rack 14. The wire-drawing drive motor 521 is fixed to the base 511. The gear 522 is connected to the shaft of the wire-drawing drive motor 521 and meshes with the rack 14. Specifically, the wire-drawing drive motor 521 drives the gear 522 to drive the base 511 to slide.

[0096] In this embodiment, the clamping member 513 is a clamping cylinder provided with a clamp 5131 , and the clamping cylinder drives and controls the clamp 5131 , thereby achieving clamping of the wire body.

[0097] In this embodiment, Figure 7-8 As shown, the down-line unit 50 further includes a fourth proximity switch 54, which is fixed to the frame 10 and close to the insertion cavity 21. The fourth proximity switch 54 is electrically connected to the wire pulling drive module 52. The base 511 is provided with a clamping sensor 5111. When the fourth proximity switch 54 senses the approach of the clamping sensor 5111, the wire pulling drive module 52 stops driving the base 511, and the clamping member 513 clamps the needle sleeve 10a. Specifically, when the fourth proximity switch 54 senses the approach of the clamping sensor 5111, the base 511 approaches the insertion cavity 21. At the same time, the clamp 5131 of the clamping member 513 enters the insertion cavity 21. The clamping member 513 can then control the clamp 5131 to clamp the needle sleeve 10a, thereby achieving the clamping of the thread body.

[0098] In this embodiment, Figure 7 As shown, the offline unit 50 also includes a fifth proximity switch 55, which is fixed to the frame 10 and away from the plug-in cavity 21. The fifth proximity switch 55 is electrically connected to the wire pulling drive module 52. When the fifth proximity switch 55 senses that the clamping sensor 5111 is approaching, the wire pulling drive module 52 stops driving the base 511, and the clamping member 513 releases the clamping of the needle sleeve 10a. Specifically, after the clamping member 513 clamps the wire body, the wire pulling drive module 52 drives the base 511 to slide, so that the clamping member 513 pulls out the clamped wire body. When the fifth proximity switch 55 senses that the clamping sensor 5111 is approaching, the wire pulling drive module 52 stops driving the base 511. At this time, the clamping member 513 releases the clamping of the needle sleeve 10a, and then the wire body falls onto the wire pay-off rack 53, realizing the recovery of the wire body after plugging.

[0099] In this embodiment, when the fifth proximity switch 55 senses the approach of the clamping sensor 5111 and the wire driving module 52 stops driving the base 511 , the wire breaking unit 60 first cuts the wire and then causes the clamping member 513 to release the clamping of the needle sleeve 10 a .

[0100] In one embodiment, Figure 7-8 As shown, the offline unit 50 also includes a detection module 56, which is installed on the frame 10 and electrically connected to the wire pulling drive module 52. The detection module 56 is used to control the sliding distance of the base 511 after the clamping member 513 clamps the wire body by detecting the wire body after insertion. Specifically, due to the phenomenon that the wire body deviates during the insertion and installation of the needle sleeve 10a, the needle sleeve 10a is not fixed stably, etc., the detection module 56 can detect defective products after the wire body is plugged in. When it is detected that the plugging of the wire body is unqualified, the wire pulling drive module 52 shortens the sliding distance of the base 511, so that the length of the qualified wire body is different from the length of the unqualified wire body, and the unqualified wire body is distinguished from the qualified wire body, thereby providing convenience for the subsequent classification and processing of qualified and unqualified wire bodies.

[0101] In this embodiment, Figure 7-8 As shown, the detection module 56 includes visual cameras 561, which are located on the upper and lower sides of the clamping member 513 and are used to photograph the clamping end of the clamping member 513. Specifically, by photographing the clamping end of the clamping member 513, the visual cameras 561 can identify the needle sleeve 10a clamped by the clamping member 513 and observe whether the end of the wire is properly inserted into the needle sleeve 10a. Based on the recognition results of the visual cameras 561, the controller causes the wire driving module 52 to control the driving distance of the base 511.

[0102] In this embodiment, when the visual camera 561 recognizes that the connection of the wire is unqualified, the controller controls the wire pulling drive module 52 to shorten the driving distance of the base 511. When the base 511 stops sliding, the wire breaking unit 60 starts to cut the wire, and the clamping member 513 releases the clamping of the wire, allowing the wire to fall onto the wire pay-off rack 53.

[0103] In this embodiment, Figure 1 and 7 As shown, the pay-off rack 53 includes a good product pay-off box 531 and a defective product pay-off box 532. The good product pay-off box 531 is located on the lower side of the clamping module 51, and the defective product pay-off box 532 is arranged on the inner side of the good product pay-off box 531 and is shorter than the good product pay-off box 531. Specifically, the good product pay-off box 531 is relatively long. The longer good products with qualified connection detected by the detection module 56 will be classified into the good product pay-off box 531, and the shorter defective products with unqualified connection detected by the detection module 56 will be classified into the defective product pay-off box 532, thereby providing convenience for the classification and processing of qualified and defective products.

[0104] In one embodiment, Figure 3-5 As shown, the plug-in device further includes a wire breaking unit 60, which is fixed to the frame 10 and is located on the side of the plug-in unit 20 close to the wire cutting unit 30, and is used to cut the wire after the lower wire unit 50 pulls it out. Specifically, after the wire clamping unit 40 is moved and inserted into the needle sleeve 10a, the lower wire unit 50 pulls out the wire, and after pulling it out a certain distance, the wire is cut by the wire breaking unit 60. After the cutting is completed, the plug-in of the wire section is completed, and then the subsequent wires can be plugged in through a cycle.

[0105] In this embodiment, the wire is wound on a material rack, and during the splicing operation, it is unloaded through the material rack to the guide wheel rack 44 .

[0106] It can be understood that the wire cutting unit 60 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.

[0107] In one embodiment, Figure 3-5 As shown in Figure 10, the wire breaking unit 60 includes a wire breaking drive 61 and two wire cutting knives 62. The two wire cutting knives 62 are arranged opposite to each other. The two wire cutting knives 62 can cut the wire body by approaching each other, or enter the cutting position of the insulation skin cut by the cutting unit 30 by approaching each other, so that the wire cutting knife 62 moves away from the plug-in cavity 21 through the wire body clamping unit 40, and strips the insulation skin cut by the cutting unit 30 from the wire core. The wire breaking drive 61 is connected to the two wire cutting knives 62 for driving the two wire cutting knives 62 to approach or move away from each other.

[0108] Specifically, through this arrangement, the wire breaking unit 60 can have two functions: cutting the wire body and cooperating with the wire body clamping unit 40 to strip the cut insulation. On the one hand, when cutting the wire body, the wire breaking drive 61 drives the two wire cutting knives 62 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 61 drives the two wire cutting knives 62 to approach each other, so that the two wire cutting knives 62 enter the cutting position of the insulation. After the wire cutting knives 62 enter the cutting position of the insulation, the wire body clamping unit 40 moves away from the plug-in cavity 21. The wire cutting knife 62 blocks the insulation, so that the two wire cutting knives 62 will drive the cut insulation to be stripped from the wire core, and finally realize the automatic stripping of the insulation.

[0109] In this embodiment, Figure 3-5As shown, the rack 10 is provided with a first proximity switch 11, a second proximity switch 12 and a third proximity switch 13, which are located on one side of the sliding seat 41 and are sequentially spaced in the direction of the wire breaking unit 60. The sliding seat 41 is provided with a sensing part. The first proximity switch 11 is electrically connected with the laser generator 31 and the stripping driving motor 431. The second proximity switch 12 is electrically connected with the wire breaking driving part 61. The third proximity switch 13 is electrically connected with the stripping driving motor 431. Specifically, when the sliding seat 41 slides in the direction of the plug-in cavity 21 by the driving of the stripping driving motor 431, the first proximity switch 11 senses the approach of the sensing part, the stripping driving motor 431 stops running, the laser generator 31 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 off, the stripping driving motor 431 drives the sliding seat 41 to continue to slide in the direction of the plug-in cavity 21, the second proximity switch 12 senses the approach of the sensing part, the stripping driving motor 431 stops, the wire breaking driving part 61 drives the two wire breaking knives 62 to approach each other, so that the two wire breaking knives 62 enter the cut-off part of the insulation skin. After the wire breaking knives 62 enter the cut-off part of the insulation skin, the stripping driving motor 431 drives the sliding seat 41 to move away from the plug-in cavity 21 until the first proximity switch 11 senses the approach of the sensing part again, the stripping driving motor 431 stops. At this time, the two wire breaking knives 62 will peel off the cut-off insulation skin from the wire core. Then, the stripping driving motor 431 drives the sliding seat 41 to continue to slide in the direction of the plug-in cavity 21 until the third proximity switch 13 senses the approach of the sensing part, the stripping driving motor 431 stops. At this time, the plug-in end of the wire body with the peeled skin is plugged into the needle sleeve 10a, and the plugging of the wire body is finally completed.

[0110] In this embodiment, as shown in Figure 3-5 As shown in Figs. 6 and 10, the opposite side of the two wire breaking knives 62 is provided with staggered shearing inclined surfaces 621, so that the two wire breaking knives 62 can form shearing on the wire body by approaching each other. Specifically, the shearing inclined surfaces 621 of the wire breaking knives 62 can form shearing on the wire body by approaching each other, which provides convenience for cutting the wire body.

[0111] In this embodiment, as shown in Figure 3-5 As shown in Figs. 6 and 10, the shearing inclined surfaces 621 are provided with a plurality of spaced accommodating grooves 622 for accommodating the wire body. Specifically, as the wire body is cut by the two wire breaking knives 62, the two sides of the cut wire body will enter the accommodating grooves 622 of the two wire breaking knives 62 and be accommodated by the accommodating grooves 622, so as to avoid the wire body being deformed due to being pressed by the wire breaking knives 62.

[0112] In one embodiment, the wire-breaking drive member 61 includes a double-ended clamping cylinder, and the two wire-breaking knives 62 are respectively fixed to the two driving ends of the double-ended clamping cylinder. Specifically, the double-ended clamping cylinder drives the two driving ends to approach each other, thereby driving the two wire-breaking knives 62 to approach each other.

[0113] In one embodiment, Figure 3-5 As shown in FIG10 , the wire cutting unit 60 further includes a wire cutting adjustment cylinder 63, which is fixed to the frame 10. The wire cutting drive member 61 is mounted on the wire cutting adjustment cylinder 63 and can be moved by the drive of the wire cutting adjustment cylinder 63. Specifically, the wire cutting adjustment cylinder 63 drives the wire cutting drive member 61 to move, thereby adjusting the positions of the two wire cutting knives 62, thereby facilitating wire cutting.

[0114] It is understandable that the needle sheath 10a can be placed in the insertion cavity 21 manually, or transported to the insertion cavity 21 by a feeding device such as a belt or a vibrating plate.

[0115] In one embodiment, Figure 1-2 As shown, the plugging device further includes a feeding unit 70, a grabbing unit 80, and a transfer unit 90 mounted on the frame 10. The feeding unit 70 is used to feed the needle sleeve 10a. The grabbing unit 80 is disposed at the discharge end of the feeding unit 70 and is used to grab a single needle sleeve 10a fed to the discharge end. The transfer unit 90 is used to grab the needle sleeve 10a from the grabbing unit 80 and transfer the grabbed needle sleeve 10a to the plugging cavity 21. Specifically, when the needle sleeve 10a is installed in the plugging cavity 21, the feeding unit 70 feeds the needle sleeve 10a toward the discharge end, the grabbing unit 80 grabs a single needle sleeve 10a fed to the discharge end, and the transfer unit 90 grabs the needle sleeve 10a grabbed by the grabbing unit 80 and transfers the grabbed needle sleeve 10a to the plugging cavity 21. Through the above steps, the needle sheath 10a can be automatically installed in the insertion cavity 21, which provides convenience for the installation of the needle sheath 10a in the insertion cavity.

[0116] In one embodiment, Figure 1-2 As shown, the discharge unit 70 includes a vibrating plate 71 and a first clamp 72. The vibrating plate 71 is provided for discharging needle sleeves 10a. The first clamp 72 is installed at the discharge end of the vibrating plate 71 and is used to clamp the needle sleeves 10a at the discharge end of the vibrating plate 71. The gripping unit 80 is used to grip the needle sleeves 10a of the clamp. Specifically, the vibrating plate 71 drives the needle sleeves 10a to discharge toward the discharge end through vibration. When the needle sleeves 10a are discharged to the discharge end, the first clamp 72 clamps the needle sleeves 10a to prevent the needle sleeves 10a at the discharge end from being squeezed out by subsequent needle sleeves 10a. By clamping the needle sleeves 10a, it is convenient for the gripping unit 80 to grab the needle sleeves 10a.

[0117] In one embodiment, Figure 11As shown, the grabbing unit 80 includes a dislocation driver 81, a grabbing driver 82 and a second clamper 83. The dislocation driver 81 is fixed to the frame 10 and is located at the discharge end of the blanking unit 70. The grabbing driver 82 is slidably connected to the dislocation driver 81 and can be driven by the dislocation driver 81 to be opposite to or dislocation with the discharge end of the blanking unit 70. The second clamper 83 is slidably connected to the grabbing driver 82 and can be driven by the grabbing driver 82 toward the discharge end of the blanking unit 70 to clamp the needle sleeve 10a at the discharge end. Specifically, after the blanking unit 70 discharges the needle sleeve 10a to the discharge end, the grabbing driver 82 drives the second clamper 83 to move toward the discharge end of the blanking unit 70 to clamp the needle sleeve 10a at the discharge end of the blanking unit 70. After completing the clamping of the needle sleeve 10a, the grabbing driver 82 drives the second clamper 83 to move in the direction away from the discharge end of the blanking unit 70, so that the needle sleeve 10a is separated from the other needle sleeves 10a at the discharge end, and then the dislocation driver 81 drives the grabbing driver 82 to slide, so that the second clamper 83 is dislocated with the discharge end of the blanking unit 70, and the transfer unit 90 can transfer the needle sleeve 10a to the insertion cavity 21 by grabbing the needle sleeve 10a of the second clamper 83.

[0118] In this embodiment, the first clamper 72 and the second clamper 83 have the same structure as the wire clamping module 51 .

[0119] In one embodiment, Figure 11 As shown, the transfer unit 90 includes a transfer robot 91, a pusher 92 and a material picking rack 93. The transfer robot 91 is installed on the frame 10, and the material picking rack 93 is installed on the transfer robot 91. The pusher 92 is located on one side of the discharge end of the unloading unit 70 and is used to push the needle sleeve 10a of the second clamper 83. The material picking rack 93 is installed on the transfer robot 91 and can be moved to the second clamper 83 or the plug-in cavity 21 by the transfer robot 91. When moving to the second clamper 83, the needle sleeve 10a is grasped by the pusher 92, and when moving to the plug-in cavity 21, the grasped needle sleeve 10a is installed in the plug-in cavity 21.

[0120] Specifically, through the above arrangement, when the transfer unit 90 is performing the transfer work of the needle sleeve 10a on the second clamper 83, the transfer robot 91 first drives the material picking rack 93 to move to the side of the needle sleeve 10a clamped by the second clamper 83, so that the socket on the material picking rack 93 is docked with the needle sleeve 10a, and then the second clamper 83 releases the clamping of the needle sleeve 10a, and the pusher 92 pushes the needle sleeve 10a into the socket of the material picking rack 93, thereby completing the grabbing of the needle sleeve 10a on the second clamper 83. After completing the grabbing of the needle sleeve 10a, the transfer robot 91 drives the material picking rack 93 to move to the insertion cavity 21, and places the needle sleeve 10a in the insertion cavity 21, thereby finally realizing the automatic installation of the needle sleeve 10a.

[0121] In the embodiment, as shown in Figure 11 The pushing device 92 includes a pushing driving part 931 and a pushing block 932 provided with a needle, and the pushing driving part 931 drives the pushing block 932 to move towards the second gripper 83, so as to push the needle sleeve 10a gripped by the second gripper 83 to the insertion hole of the taking rack 93 through the needle.

[0122] In the embodiment, the taking rack 93 has two insertion holes, one of which is used to grab the needle sleeve 10a, and the other is used to grab another needle sleeve 10a, so as to realize the simultaneous transfer and installation of two needle sleeves 10a.

[0123] The embodiment of the application also provides a plug-in method, as shown in Figure 12 The plug-in method is executed by the plug-in device, and includes the following steps.

[0124] The wire body clamping unit 40 clamps the wire body;

[0125] The needle sleeve 10a is installed in the plug-in cavity 21 of the plug-in unit 20;

[0126] The cutting unit 30 cuts the insulation skin of the plug-in end of the wire body;

[0127] The insulation skin of the plug-in end of the wire body is stripped;

[0128] The wire body clamping unit 40 moves towards the plug-in cavity 21, so as to drive the clamped wire body to plug into the needle sleeve 10a of the plug-in cavity 21 through the plug-in end;

[0129] The wire body after the plug-in of the needle sleeve 10a is pulled out by the wire pulling unit 50.

[0130] Specifically, through the above process steps, the automatic plug-in of the wire body can be realized, the labor required for the plug-in of the wire body is effectively reduced, and the plug-in efficiency of the wire body is improved, so as to meet the plug-in process requirement of the wire body.

[0131] In one of the embodiments, in the step of installing the needle sleeve 10a in the plug-in cavity 21 of the plug-in unit 20, the feeding unit 70 feeds the needle sleeve 10a towards the discharge end, the grabbing unit 80 grabs the single needle sleeve 10a fed 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. Specifically, through the above steps, the automatic installation of the needle sleeve 10a to the plug-in cavity 21 can be realized, and the installation of the needle sleeve 10a in the plug-in cavity is facilitated.

[0132] In one embodiment, during the step of stripping the insulation from the connector end of the disconnected wire, the disconnection driver 61 drives the two disconnecting blades 62 toward each other, causing the two disconnecting blades 62 to enter the insulation cutoff area. The wire clamping unit 40 then moves away from the connector cavity 21, causing the two disconnecting blades 62 to strip the cut insulation. Specifically, through these steps, automatic insulation stripping is achieved, accelerating the efficiency of wire connection.

[0133] In one embodiment, in the step of pulling out the wire body after the plug-in needle sleeve 10a by the offline unit 50, the detection module 56 detects defective products after the wire body is plugged in. When it is detected that the plugging of the wire body is unqualified, the wire pulling drive module 52 shortens the sliding distance of the base 511, so that the length of the qualified wire body is different from the length of the unqualified wire body, thereby distinguishing the unqualified wire body from the qualified wire body.

[0134] In order to better understand the present invention, the following Figures 1 to 11 The technical solution of the present invention is described in detail:

[0135] When the thread body is plugged in, the vibrating disk 71 drives the needle sleeve 10a to be discharged toward the discharge end through vibration. When the needle sleeve 10a is discharged to the discharge end, the first clamper 72 clamps the needle sleeve 10a. After the first clamper 72 clamps the needle sleeve 10a, the grabbing driver 82 drives the second clamper 83 to move toward the discharge end of the discharge unit 70 to clamp the needle sleeve 10a of the first clamper 72. After completing the clamping of the needle sleeve 10a, the grabbing driver 82 drives the second clamper 83 to move away from the discharge end of the discharge unit 70, so that the needle sleeve 10a is separated from the other needle sleeves 10a at the discharge end, and then the dislocation driver 81 drives the grabbing driver 82 to slide, so that the second clamper 83 is dislocated with the first clamper 72, and then the transfer robot 91 first drives the picking rack 93 to move to the second clamper 83 to clamp After the needle sleeve 10a is grabbed, the second clamper 83 returns to the first clamper 72 and grabs another needle sleeve 10a, so that the transfer robot 91 grabs two needle sleeves 10a at the same time through the material rack 93. After the grabbing of the two needle sleeves 10a is completed, the transfer robot 91 places the two needle sleeves 10a in the plug-in cavities 21 of the two plug-in units 20 respectively. When the needle sleeve 10a is placed in the plug-in cavity 21, the pressing drive 23 is started, driving the pressing ring 24 to rotate a small angle, driving the pressing rod 25 to press the needle sleeve 10a, and fixing the needle sleeve 10a;

[0136] After the wire body passes through between the two rows of guide wheels, it enters the clamping module 42, and the wire body passes between the limit base 421 and the clamping block 422 of the clamping module 42. The clamping driver 423 drives the clamping block 422 to move in the direction of the limit base 421 to limit the wire body. When 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 11 senses the approach of the sensing part, the plug-in stripping drive motor 431 stops running, and the laser generator 31 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 in the direction of the plug-in cavity 21. When the second proximity switch 12 senses the approach of the sensing part, the plug-in stripping drive motor 431 stops running, and the laser generator 31 starts. By forming a laser, the insulation skin of the plug-in end of the wire body is cut off. After the insulation skin is cut, the plug-in stripping drive motor 431 drives the sliding seat 41 to continue sliding in the direction of the plug-in cavity 21. The stripping drive motor 431 stops, and the wire-breaking drive member 61 drives the two wire-breaking knives 62 to approach each other, so that the two wire-breaking knives 62 enter the cutting position of the insulation. After the wire-breaking knives 62 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 11 again senses the proximity of the sensing member, and the stripping drive motor 431 stops. At this time, the two wire-breaking knives 62 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 13 senses the proximity of the sensing member, 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 the plug-in of the wire body is finally completed.

[0137] After the insertion of the wire body is completed, the pressing drive member 23 is started, driving the pressing ring 24 to rotate. During the rotation of the pressing ring 24, the pressing rod 25 is separated from the recessed portion 241, so that the pressing ring 24 drives each pressing rod 25 to slide toward the insertion cavity 21 through the inner side wall, and finally presses the needle sleeve 10a toward the wire core, and finally locks the wire core;

[0138] After the needle sleeve 10a is locked with the wire body, the wire-releasing drive motor 521 drives the base 511 to move toward the plug-in cavity 21. When the fourth proximity switch 54 senses the approach of the clamping sensor 5111, the base 511 approaches the plug-in cavity 21. At the same time, the clamp 5131 of the clamping member 513 enters the plug-in cavity 21. The clamping member 513 can clamp the needle sleeve 10a by controlling the clamp 5131. After the clamping member 513 clamps the wire body, the wire-pulling drive module 52 drives the base 511 to slide, so that the clamping member 513 pulls out the clamped wire body. When the fifth proximity switch 55 senses the clamping sensor When the device 5111 approaches, the wire pulling drive module 52 stops driving the base 511, the wire breaking unit 60 cuts off the wire, and then the clamping member 513 releases the clamping of the needle sleeve 10a, so that the wire falls into the good product collection box 531. When the visual camera 561 recognizes that the connection of the wire is unqualified, the controller controls the wire pulling drive module 52 to shorten the driving distance of the base 511. When the base 511 stops sliding, the wire breaking unit 60 starts to cut off the wire, and the clamping member 513 releases the clamping of the wire, so that the wire falls into the defective product collection box 532, which provides convenience for the classification and processing of qualified and unqualified products.

[0139] Finally, the automatic plugging of the wires is completed, which effectively reduces the manpower required for the plugging of the wires and improves the plugging efficiency of the wires.

[0140] 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.
