Description

Technical Field

[0001] The utility model relates to the technical field of wire plug-in connection, in particular to a wire pulling-out 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.

[0003] For example, a wire harness crimping device disclosed in the patent document with announcement number CN219419811U comprises a base, a crimping mechanism, a needle sleeve feeding mechanism and a manual threading mechanism. The manual threading mechanism comprises a wire harness guide and a wire harness fixing member. 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 smoothly pass the wire harness into 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.

[0004] After the existing wire harness crimping equipment completes the connection between the wire body and the needle sleeve, the wire body needs to be pulled out and placed on the material rack. The existing wire body is generally pulled out manually, which consumes a lot of manpower during the wire pulling process and causes inconvenience to the wire connection work. Utility Model Content

[0015] In some embodiments, the wire pulling device also includes a first proximity switch, which is fixed to the frame and close to the plug-in cavity. The first proximity switch is electrically connected to the wire pulling drive module. The base is provided with a clamping sensor. When the first proximity switch senses that the clamping sensor is approaching, the wire pulling drive module stops driving the base, and the clamping member clamps the needle sleeve.

[0016] In some embodiments, the wire pulling device also includes a second proximity switch, which is fixed to the frame and away from the plug-in cavity.

[0019] In some embodiments, the wire rack includes a good wire box and a defective wire box, the good wire box is located on the lower side of the wire clamping module, and the defective wire box is arranged on the inner side of the good wire box and is shorter than the good wire box.

[0020] The wire pulling device provided by the present invention can clamp the wire body after the needle sleeve is inserted into the plug-in cavity, and pull out the wire body by sliding away from the plug-in cavity. The wire pay-off frame is located below the wire clamping module, and the wire pulling driving module can drive the wire clamping module.

After the wire body is completely drawn out, the wire clamping module releases the clamping of the needle sleeve, so that the plugged wire body falls on the wire pay-off frame, thereby realizing automatic unloading of the plugged wire body, reducing the manpower required for wire unloading, speeding up the unloading efficiency of the wire body, and providing convenience for subsequent plugging operations of the wire body.

[0030] 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.

[0031] In order to solve the technical problem in the prior art that the wire body needs to be pulled out manually after being plugged in, resulting in a large amount of manpower being consumed in the wire pulling-out process, the utility model provides a wire pulling-out device for being arranged on a wire plugging device, the wire plugging device being used to plug the plugging end of the wire body into the pin sleeve, the wire body including a wire core and an insulating skin wrapped around the wire core, and the wire pulling-out device automatically unloads the wire body after being plugged in, thereby reducing the manpower required for wire unloading, speeding up the wire unloading efficiency, and providing convenience for subsequent wire plugging operations.

[0032] like Figure 1 As shown, the wire 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 pulling-out device 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, which is provided for fixing the needle sleeve; the wire cutting unit 30 is located on one side of the plug-in unit 20, and is used to cut off the insulating 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 skin cutting unit, and is used to clamp the wire, and can be moved toward the plug-in cavity so that the plug-in end of the clamped wire is plugged into the needle sleeve of the plug-in cavity; the wire pulling-out device 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 after the pin sleeve is plugged away from the plug-in unit 20.

[0033] Specifically, when the wire body is being plugged in, the wire body is first clamped by the wire body clamping unit 40, and the needle sleeve is arranged in the plug-in cavity of the plug-in unit 20, and then the insulation skin of the plug-in end of the wire body 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, and the clamped wire body is plugged into the needle sleeve of the plug-in cavity 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 wire body pulling-out device 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.

[0034] In this embodiment, the wire body is mainly a conductive wire.

[0035] like Figure 1-3As shown, the wire pulling-out device 50 provided in the embodiment of the utility model includes a wire clamping module 51, a wire pulling drive module 52 and a wire pay-off rack 53. The wire clamping module 51 is used to clamp the wire after the needle sleeve is inserted and pull out the wire by sliding. The wire pay-off rack 53 is located below the wire clamping module 51 and is used to place the pulled-out wire. The wire pulling drive module 52 is connected to the wire clamping module 51 and is used to drive the wire clamping module 51 to slide.

[0036] Specifically, the wire pulling device 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 can clamp the wire after the needle sleeve is inserted by sliding toward the plug-in cavity, and pull out the wire by sliding away from the plug-in cavity. The wire pay-off frame 53 is fixed to the frame 10 and is located below the wire clamping module 51. 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 and locked with the needle sleeve, the wire pulling drive module 52 drives the wire clamping module 51. After the module 51 slides toward the plug-in cavity, it clamps the needle sleeve of the plug-in cavity 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 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, 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.

[0037] 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.

[0038] In this embodiment, the clamping module 51 is slidably connected to the frame 10. The clamping module 51 can clamp the wire after the needle sleeve is inserted by sliding toward the insertion cavity, and pull out the wire by sliding away from the insertion cavity.

[0039] In one embodiment, Figure 2-4 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 drive module 52 drives the base 511 to move to a certain position in the direction of the plug-in cavity, and the clamping member 513 is started to clamp the needle sleeve in the plug-in cavity. After clamping the needle sleeve, when the wire pulling drive module 52 drives the base 511 to move to a certain position in the direction away from the plug-in cavity, the clamping member 513 releases the clamping of the needle sleeve, so that the wire body after plugging falls on the wire pay-off frame 53.

[0040] In one embodiment, the line pulling-out device 50 includes a frame 10 , the frame 10 is provided with a slide rail, and the base 511 is slidably connected to the frame 10 via the slide rail to achieve stable sliding along the frame 10 .

[0041] In this embodiment, Figure 4 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.

[0042] 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.

[0043] In this embodiment, Figure 2-3 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.

[0044] 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.

[0045] In this embodiment, Figure 2-3 As shown, the wire pulling device 50 also includes a first proximity switch 54, which is fixed to the frame 10 and close to the plug-in cavity. The first 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 first 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. Specifically, when the first proximity switch 54 senses the approach of the clamping sensor 5111, the base 511 approaches the plug-in cavity. At the same time, the clamp 5131 of the clamping member 513 enters the plug-in cavity. The clamping member 513 can clamp the needle sleeve by controlling the clamp 5131, thereby achieving the clamping of the wire.

[0046] In this embodiment, Figure 2As shown, the wire pulling device 50 also includes a second proximity switch 55, which is fixed to the frame 10 and away from the plug-in cavity. The second proximity switch 55 is electrically connected to the wire pulling drive module 52. When the second 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. Specifically, after the clamping member 513 clamps the wire, the wire pulling drive module 52 drives the base 511 to slide, so that the clamping member 513 pulls out the clamped wire. When the second 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, and then the wire falls on the wire pay-off rack 53, realizing the recovery of the wire after plugging.

[0047] In this embodiment, when the second 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.

[0048] In one embodiment, Figure 2-3 As shown, the wire pulling device 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 process of plugging and inserting it into the needle sleeve, the needle sleeve is unstable, 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.

[0049] In this embodiment, Figure 2-3 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 clamped by the clamping member 513 and observe whether the end of the wire is properly inserted into the needle sleeve. 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.

[0050] 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.

[0051] In this embodiment, Figure 1-2 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, and 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 good and defective products.

[0052] In order to better understand the present invention, the following Figures 1 to 4 The technical solution of the utility model is described in detail:

[0053] When the wire body is being plugged in, the wire body is first clamped by the wire body clamping unit 40, and the needle sleeve is arranged in the plug-in cavity of the plug-in unit 20. Then, the insulation skin of the plug-in end of the wire body is cut off by the 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, and the clamped wire body is plugged into the needle sleeve of the plug-in cavity through the plug-in end to complete the plug-in of the wire body. After the wire body is plugged in, the wire-releasing drive motor 521 drives the base 511 to move toward the plug-in cavity. When the first proximity switch 54 senses the approach of the clamping sensor 5111, the base 511 approaches the plug-in cavity. At the same time, the clamp 5131 of the clamping member 513 enters the plug-in cavity, and the clamping member 513 can control the clamp 5131 to insert the needle sleeve into the plug-in cavity. The wire is clamped. After the clamping member 513 clamps the wire, the wire pulling drive module 52 drives the base 511 to slide, so that the clamping member 513 pulls out the clamped wire. When the second proximity switch 55 senses the approach of the clamping sensor 5111, the wire pulling drive module 52 stops driving the base 511, and the wire breaking unit 60 cuts off the wire, and then the clamping member 513 releases the clamping of the needle sleeve, so that the wire falls into the good product release box 531. When the visual camera 561 recognizes that the wire connection 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 cuts off the wire, and the clamping member 513 releases the clamping of the wire, so that the wire falls into the defective product release box 532, which provides convenience for the classification and processing of qualified and unqualified products.

[0054] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention.
