Description

Technical Field

[0001] The present invention relates to the technical field of wire plug-in, and in particular to a plug-in device and a plug-in method. 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, with both ends welded into a bundle, one end pressed into a sleeve, and the other end upset and raised. They are light in weight, small in size, and have reliable contact. They are widely used in electronic components. In the process of producing 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 a 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 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.

[0004] Although the wires can be plugged in through the wire crimping equipment, the pulling in of the wires before plugging in, the stripping of the wires, and the pulling out of the wires after plugging in all need to be done manually, resulting in a low degree of automation of the plugging equipment. This in turn results in a large amount of manpower consumed in the wire plugging process and low plugging efficiency, which makes it difficult to meet the actual production needs of wire plugging. Summary of the invention

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.

[0020] In order to solve the technical problem that the degree of automation of the plugging equipment in the prior art is low, resulting in a large amount of manpower consumed in the plugging process of the wire body and low efficiency; the embodiment of the present invention provides a plugging equipment and a plugging method.

The plugging equipment can realize the automatic plugging of the wire body to the pin sleeve 10a, thereby effectively reducing the manpower required for the plugging of the wire body, improving the plugging efficiency of the wire body, and finally meeting the plugging process requirements of the wire body.

[0021] 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 lower wire unit 50.

[0022] Specifically, the plug-in device is provided with a frame 10, a plug-in unit 20, a wire cutting 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 wire cutting 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 wire cutting 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 plug-in is completed. By setting 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, and 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 wire body plug-in end 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, and the plug-in of the wire body can be completed. After the wire body is plugged in, it can be pulled out by the down-line 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 plug-in process requirements of the wire body.

[0023] In this embodiment, the line body is a conductive wire.

[0024] 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 lower wire unit 50 of the plug-in device are each provided with two groups, so that the plug-in device can plug two groups of wires at the same time.

[0025] It can be understood that the frame 10 can be any frame structure that can be supported on the ground.

[0026] 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.

[0027] In one embodiment, if Figure 3-5 As shown in Figure 10, the plug-in unit 20 includes a plug-in frame 22, a clamping drive member 23, a clamping 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 clamping 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 clamping 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 clamping ring 24, so that the clamping ring 24 drives each pressure rod 25 toward the plug-in cavity by rotating. The connecting cavity 21 slides, and the clamping drive 23 is connected to the clamping ring 24, which is used 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 to drive 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 connecting 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.

[0028] In this embodiment, the clamping driving member 23 is a cylinder, and a hinged wall is provided on the outer side of the clamping ring 24, and the hinged wall is hinged to the driving end of the clamping driving member 23. When the clamping driving member 23 drives the driving end to move, the clamping ring 24 is driven to rotate through the hinged wall.

[0029] It can be understood that the wire cutting unit 30 can cut the insulation of the wire body by cutting the peripheral side of the wire body with a cutting knife, or cut the insulation of the wire body by cutting the wire body on both sides with a cutting knife.

[0030] In one embodiment, if Figure 1 and 3As 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 off the insulation skin of the wire body.

[0031] It can be understood that the wire clamping unit 40 can be a clamping cylinder installed on the slide, or a manipulator 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.

[0032] It can be understood that the movement of the wire clamping unit 40 can be controlled manually through a driving component.

[0033] In one embodiment, if Figure 1-5 As 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 slidably connected to the frame 10 in a direction close to or away from the plug-in cavity 21. The stripping drive module 43 is connected to the sliding seat 41 and is used to drive the sliding seat 41 to slide. The clamping module 42 is installed on the sliding seat 41 and is used to clamp the wire.

[0034] 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 arrangement, 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.

[0035] It can be understood that the clamping module 42 can be a clamping cylinder or two clamping members 513 arranged opposite to each other.

[0036] 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 in a direction close to or away from the limiting base 421.

[0037] 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.

[0038] In this embodiment, a wire body cavity for accommodating the wire body is formed between the clamping block 422 and the limiting base 421 , and the wire body cavity accommodates and limits the wire body to prevent the wire body from being damaged.

[0039] It can be understood 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. In this embodiment, Figure 3-5 As shown, the plugging and stripping drive module 43 includes a plugging and stripping drive motor 431 and a screw rod, the screw rod axially extends toward the plug-in cavity 21 and is rotatably connected to the frame 10, the plugging and stripping drive motor 431 is connected to the screw rod to drive the screw rod to rotate, and the sliding seat 41 is threadedly connected to the screw rod through a screw nut. Specifically, the first motor drives the screw rod to rotate, thereby driving the sliding seat 41 to slide.

[0040] In this embodiment, 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 edge and the first slide rail can improve the stability of the sliding seat 41 during the sliding process.

[0041] In this embodiment, Figure 1 and 3 -5, the wire clamping unit 40 includes a guide wheel frame 44, which is fixed to the sliding seat 41. The guide wheel frame 44 is provided with two opposite rows of guide wheels, and the two rows of guide wheels are provided for the wire to pass through and guide the wire. Specifically, after the wire passes through the two rows of guide wheels, it enters the clamping module 42 and is clamped by the clamping module 42. The guide wheel frame 44 can guide the wire to prevent the wire from deviating.

[0042] It can be understood that the wire body can be segmented before the plug-in device is plugged in, and then after the plug-in of one section of the wire body is completed, the plug-in of another section of the wire body is carried out, or the wire body can be cut after the plug-in device completes the plug-in.

[0043] It can be understood that the down-line unit 50 can be a driving structure such as a belt, a robot, etc. connected to the plug-in cavity 21 and can drive the line body to output.

[0044] In one embodiment, if Figure 1 and 7 -8, the down-line unit 50 includes 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. The wire clamping module 51 can clamp the wire body behind the plug-in needle sleeve 10a by sliding toward the plug-in cavity 21, and pull out the wire body by sliding away from the plug-in cavity 21. The wire pay-off frame 53 is fixed to the frame 10 and is located below the wire clamping module 51, and is used for placing the pulled-out wire body. The wire pulling drive module 52 is connected to the wire clamping module 51, and is used for driving the wire clamping module 51 to slide.

[0045] Specifically, the down-line unit 50 is provided with a wire clamping module 51, a wire pulling driving 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 driving 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 driving 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 the wire body is completely led out, the wire clamping module 51 releases the clamping of the needle sleeve 10a, so that the plug-in wire body falls on the wire pay-off rack 53, thereby realizing automatic unloading of the plug-in wire body, reducing the manpower required for unloading the wire body, speeding up the unloading efficiency of the wire body, and providing convenience for the subsequent plug-in operation of the wire body.

[0046] It can be understood that the wire clamping module 51 can be any clamping device such as a robot that can clamp the wire.

[0047] In one embodiment, if 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 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, 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, and the clamping member 513 releases the clamping of the needle sleeve 10a, so that the wire after plugging falls on the wire pay-off frame 53.

[0048] In this embodiment, Fig. 9 As shown, the mounting frame 512 is provided with a straight groove 5121, and a bolt passes through the straight groove 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 frame 512 can adjust the installation position through the straight groove 5121, thereby adjusting the position of the clamping member 513, so that the clamping member 513 can clamp the wire more accurately.

[0049] 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.

[0050] In this embodiment, Figure 7-8 As shown, the wire drawing driving module 52 includes a wire-releasing driving motor 521 and a gear 522, the frame 10 is provided with a rack 14, the wire-releasing driving motor 521 is fixed to the base 511, the gear 522 is connected to the shaft of the wire-releasing driving motor 521, and meshes with the rack 14. Specifically, the wire-releasing driving motor 521 can drive the base 511 to slide by driving the gear 522.

[0051] In this embodiment, the clamping member 513 is a clamping cylinder provided with a clamp 5131 , and the clamping cylinder drives the control of the clamp 5131 to achieve clamping of the wire body.

[0052] 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 plug-in cavity 21, and is electrically connected to the wire-pulling driving module 52. The base 511 is provided with a clamping sensor 5111. When the fourth proximity switch 54 senses that the clamping sensor 5111 is approaching, the wire-pulling driving 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 that the clamping sensor 5111 is approaching, the base 511 is close to the plug-in cavity 21, and at the same time, the clamp 5131 of the clamp 513 enters the plug-in cavity 21, and the clamp 513 can clamp the needle sleeve 10a by controlling the clamp 5131, thereby clamping the wire body.

[0053] In this embodiment, Figure 7 As shown, the down-line 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 driving module 52. When the fifth proximity switch 55 senses that the clamping sensor 5111 is approaching, the wire-pulling driving 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 driving 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 driving 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 on the wire-paying frame 53, so as to realize the recovery of the wire body after plugging.

[0054] 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 10a.

[0055] 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 plugging. Specifically, due to the phenomenon that the wire body deviates during the plugging and inserting 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 facilitating the subsequent classification and processing of qualified wire bodies and unqualified wire bodies.

[0056] In this embodiment, Figure 7-8 As shown, the detection module 56 includes a visual camera 561, which is located at the upper and lower sides of the clamping member 513 and is used to photograph the clamping end of the clamping member 513. Specifically, the visual camera 561 can identify the needle sleeve 10a clamped by the clamping member 513 by photographing the clamping end of the clamping member 513, and observe whether the end of the wire body is intactly plugged into the needle sleeve 10a. The controller controls the wire driving module 52 to control the driving distance of the base 511 according to the recognition of the visual camera 561.

[0057] 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.

[0058] In this embodiment, Figure 1 and 7 As shown, the wire rack 53 includes a good wire box 531 and a bad wire box 532. The good wire box 531 is located at the lower side of the clamping module 51, and the bad wire box 532 is arranged inside the good wire box 531 and is shorter than the good wire box 531. Specifically, the good wire box 531 is relatively long, and the longer good wires with qualified connection detected by the detection module 56 will be classified into the good wire box 531, and the shorter bad wires with unqualified connection detected by the detection module 56 will be classified into the bad wire box 532, thereby providing convenience for the classification and processing of qualified and bad products.

[0059] In one embodiment, if 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 one side of the plug-in unit 20 close to the wire cutting unit 30, and is used to cut off the wire body after the lower wire unit 50 pulls out. Specifically, after the plug-in is inserted into the needle sleeve 10a by the movement of the wire body clamping unit 40, the lower wire unit 50 pulls out the wire body, and after pulling out a certain distance, the wire is cut off by the wire breaking unit 60. After the cutting is completed, the plug-in of the wire body section can be completed, and then the subsequent wire body can be plugged in through a cycle.

[0060] 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 .

[0061] 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.

[0062] In one embodiment, if Figure 3-5 As shown in Figure 10, the wire breaking unit 60 includes a wire breaking drive 61 and two wire breaking knives 62. The two wire breaking knives 62 are arranged opposite to each other. The two wire breaking knives 62 can cut the wire body by approaching each other, or by approaching each other to enter the cutting position of the insulation skin cut by the cutting unit 30, so that the wire breaking knives 62 move away from the plug-in cavity 21 through the wire body clamping unit 40 to strip the insulation skin cut by the cutting unit 30 from the wire core. The wire breaking drive 61 is connected to the two wire breaking knives 62 to drive the two wire breaking knives 62 to approach or move away from each other.

[0063] Specifically, through this arrangement, the wire breaking unit 60 can have two functions of 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 driving component 61 drives the two wire cutting knives 62 to approach each other to 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 for a distance, the wire breaking driving component 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 knives 62 block 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.

[0064] In this embodiment, Figure 3-5As shown, the frame 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 spaced in sequence toward the direction of the wire breaking unit 60, and the sliding seat 41 is provided with a sensing element, the first proximity switch 11 is electrically connected to the laser generator 31 and the plugging and stripping drive motor 431, the second proximity switch 12 is electrically connected to the wire breaking drive element 61, and the third proximity switch 13 is electrically connected to the plugging and stripping drive motor 431. Specifically, when the sliding seat 41 is driven by the stripping drive motor 431 to slide toward the plug-in cavity 21, when the first proximity switch 11 senses the approach of the sensing element, the stripping drive 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 drive motor 431 drives the sliding seat 41 to continue sliding toward the plug-in cavity 21, and when the second proximity switch 12 senses the approach of the sensing element, 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 skin. After the wire cutting knife 62 enters the cutting position of the insulation skin, 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 senses the approach of the sensing element again, and the stripping drive motor 431 stops. At this time, the two wire cutting knives 62 will drive the cut insulation skin to be stripped from the wire core, and then, the stripping drive motor 431 drives the sliding seat 41 to continue sliding in the direction of the plug-in cavity 21 again until the third proximity switch 13 senses the approach of the sensing element, 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 3-5 As shown in Figure 10, the two wire cutting knives 62 are provided with staggered shearing slopes 621 on the opposite sides, so that the two wire cutting knives 62 can shear the wire body by approaching each other. Specifically, by setting the shearing slopes 621 of the wire cutting knives 62, the wire cutting knives 62 can shear the wire body by approaching each other, which facilitates the cutting of the wire body.

[0066] In this embodiment, Figure 3-5 As shown in FIG. 10 , the shearing bevel 621 is provided with a plurality of spaced receiving grooves 622 for receiving the wire. Specifically, as the wire is cut by the two wire cutting knives 62, the two sides of the cut wire will enter the receiving grooves 622 of the two wire cutting knives 62 and be received by the receiving grooves 622, thereby preventing the wire cutting knives 62 from squeezing the wire and causing deformation of the wire.

[0067] In one embodiment, the wire-breaking drive member 61 includes a double-headed clamping cylinder, and the two wire-breaking knives 62 are respectively fixed to the two driving ends of the double-headed clamping cylinder. Specifically, the double-headed clamping cylinder can drive the two wire-breaking knives 62 to approach each other by driving the two driving ends to approach each other.

[0068] In one embodiment, Figure 3-5 As shown in FIG. 10 , the wire breaking unit 60 further includes a wire breaking adjustment cylinder 63, which is fixed to the frame 10, and a wire breaking driving member 61 is mounted on the wire breaking adjustment cylinder 63 and can be moved by the driving of the wire breaking adjustment cylinder 63. Specifically, the wire breaking adjustment cylinder 63 can adjust the positions of the two wire cutting knives 62 by driving the wire breaking driving member 61 to move, thereby facilitating the cutting of the wire body.

[0069] It can be understood that the needle sleeve 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 vibration plate.

[0070] In one embodiment, if Figure 1-2 As shown, the plug-in device further includes a feeding unit 70, a grabbing unit 80 and a transfer unit 90 installed on the frame 10, the feeding unit 70 is used to feed the needle sleeve 10a, the grabbing unit 80 is arranged at the discharge end of the feeding unit 70, and is used to grab a single needle sleeve 10a fed 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. Specifically, when the needle sleeve 10a is installed in the plug-in 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 plug-in cavity 21. Through the above steps, the automatic installation of the needle sleeve 10a into the insertion cavity 21 can be realized, which facilitates the installation of the needle sleeve 10a in the insertion cavity.

[0071] In one embodiment, if Figure 1-2 As shown, the unloading unit 70 includes a vibration plate 71 and a first clamp 72. The vibration plate 71 is provided for unloading the needle sleeve 10a. The first clamp 72 is installed at the discharge end of the vibration plate 71 and is used to clamp the needle sleeve 10a at the discharge end of the vibration plate 71. The gripping unit 80 is used to grip the needle sleeve 10a of the clamp. Specifically, the vibration plate 71 drives the needle sleeve 10a to unload toward the discharge end through vibration. When the needle sleeve 10a is unloaded to the discharge end, the first clamp 72 clamps the needle sleeve 10a to prevent the needle sleeve 10a at the discharge end from being squeezed out by the subsequent needle sleeve 10a. By clamping the needle sleeve 10a, the gripping unit 80 can easily grab the needle sleeve 10a.

[0072] In one embodiment, if Fig.11As shown, the grabbing unit 80 includes an offset driver 81, a grabbing driver 82 and a second clamper 83. The offset driver 81 is fixed to the frame 10 and is located at the discharge end of the unloading unit 70. The grabbing driver 82 is slidably connected to the offset driver 81 and can be opposite to or offset from the discharge end of the unloading unit 70 by the drive of the offset driver 81. The second clamper 83 is slidably connected to the grabbing driver 82 and can clamp the needle sleeve 10a at the discharge end of the unloading unit 70 by driving the grabbing driver 82 toward the discharge end of the unloading unit 70. Specifically, after the unloading unit 70 unloads 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 unloading unit 70 to clamp the needle sleeve 10a at the discharge end of the unloading unit 70. After completing the clamping of the needle sleeve 10a, the grabbing driver 82 drives the second clamper 83 to move in a direction away from the discharge end of the unloading unit 70, so that the needle sleeve 10a is separated from 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 unloading unit 70, and the transfer unit 90 can transfer the needle sleeve 10a to the plug-in cavity 21 by grabbing the needle sleeve 10a of the second clamper 83.

[0073] In this embodiment, the first clamper 72 and the second clamper 83 have the same structure as the wire clamping module 51 .

[0074] In one embodiment, if Fig.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.

[0075] Specifically, through the above arrangement, when the transfer unit 90 is transferring 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 plug-in cavity 21, and places the needle sleeve 10a in the plug-in cavity 21, thereby realizing the automatic installation of the needle sleeve 10a.

[0076] In this embodiment, Fig.11 As shown, the pusher 92 includes a push drive member 931 and a push block 932. The push block 932 is provided with a push pin. The push drive member 931 drives the push block 932 to move toward the second clamper 83, thereby pushing the needle sleeve 10a clamped by the second clamper 83 to the socket of the material picking rack 93 through the push pin.

[0077] In this embodiment, the material taking rack 93 has two insertion holes. After one of the insertion holes grabs the needle sleeve 10a, another needle sleeve 10a is grabbed through the other insertion hole, thereby realizing the transportation and installation of two needle sleeves 10a at the same time.

[0078] The embodiment of the present invention also provides a plug-in method, such as Fig.12 As shown, it is performed by plugging in the device: The wire clamping unit 40 clamps the wire; The needle sleeve 10a is installed in the plug-in cavity 21 of the plug-in unit 20; The wire cutting unit 30 cuts off the insulation skin of the wire plug-in end; Strip off the insulation skin of the plug-in end of the disconnect body; The line clamping unit 40 moves toward the insertion cavity 21, driving the clamped line to be inserted into the needle sleeve 10a of the insertion cavity 21 through the insertion end; The thread lowering unit 50 pulls out the thread body after the needle sleeve 10a is inserted.

[0079] Specifically, through the above process steps, automatic plugging of wires can be achieved, which effectively reduces the manpower required for plugging of wires and improves the plugging efficiency of wires, thereby meeting the plugging process requirements of wires.

[0080] In one embodiment, in the step of installing the needle sleeve 10a in the plug-in cavity 21 of the plug-in unit 20, 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, 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 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, which facilitates the installation of the needle sleeve 10a in the plug-in cavity.

[0081] In one embodiment, in the step of stripping the insulation skin of the plug-in end of the disconnected wire body, the disconnection driving member 61 drives the two disconnection knives 62 to approach each other, so that the two disconnection knives 62 enter the cut-off position of the insulation skin, and the wire body clamping unit 40 moves away from the plug-in cavity 21, so that the two disconnection knives 62 strip the cut insulation skin. Specifically, through the above steps, the insulation skin is automatically stripped, and the plug-in efficiency of the wire body is accelerated.

[0082] In one of the embodiments, in the step of pulling out the wire body after the lower line unit 50 plugs in the needle sleeve 10a, 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.

[0083] 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: When the thread body is plugged in, the vibration plate 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 material picking rack 93 to move to the second clamper 83 to clamp The second clamp 83 releases the clamp on the needle sleeve 10a, and the pusher 92 pushes the needle sleeve 10a into the insertion hole of the material picking rack 93, thereby completing the grabbing of one of the needle sleeves 10a on the second clamp 83. After completing the grabbing of the needle sleeve 10a, the second clamp 83 returns to the first clamp 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 picking rack 93. After completing the grabbing of the two needle sleeves 10a, 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 at a small angle, driving the pressing rod 25 to press the needle sleeve 10a to fix the needle sleeve 10a; After the wire passes through between the two rows of guide wheels, it enters the clamping module 42, and the wire 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. 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 element, 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 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 element, the plug-in stripping drive motor 431 starts running, and the laser generator 31 starts to cut off the insulation skin of the plug-in end of the wire. 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 skin. After the wire-breaking knives 62 enter the cutting position of the insulation skin, 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 senses the approach of the sensing member again, and the stripping drive motor 431 stops. At this time, the two wire-breaking knives 62 will drive the cut insulation skin to be stripped from the wire core, and then, the stripping drive motor 431 drives the sliding seat 41 to continue to slide in the direction of the plug-in cavity 21 again, until the third proximity switch 13 senses the approach 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; After the plugging of the wire body is completed, the pressing driving 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 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; After the needle sleeve 10a and the wire body are locked, the wire release drive motor 521 drives the base 511 to move toward the plug-in cavity 21. When the fourth proximity switch 54 senses that the clamping sensor 5111 is approaching, 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 plugging 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.

[0084] 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.

[0085] The specific implementation of the present invention described above does not constitute a limitation on the protection scope 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 protection scope of the claims of the present invention.
