[0001] The present invention relates to the technical field of wire harness processing, and in particular to a multi-core wire terminal crimping machine and a crimping method thereof. Background Art

[0002] Terminal crimping is a key step in the wire harness processing process and is widely used in the automotive, electronics, communications and other industries to ensure reliable electrical connection between the cable and the terminal.

[0003] In related technologies, the crimping of cable terminals mostly includes the following aspects. First, the cable end needs to be stripped and the insulation layer removed to ensure that the exposed part of the wire is in correct contact with the terminal during crimping. Then, the terminal is conveyed to the crimping seat of the crimping machine through the material strip, and then the exposed part of the cable end is placed in the correct position of the terminal. Finally, pressure is applied toward the crimping seat through the crimping head to press the terminal onto the bare wire part of the cable to achieve a reliable connection between the cable and the terminal.

[0004] However, for the crimping of multi-core wires, the cables need to be frequently moved for crimping, resulting in low crimping efficiency. Summary of the Invention

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] As Figures 1 to 9 shown, the multi-core wire terminal crimping machine includes a wire harness carrier 1 and a moving crimping mechanism 2, specifically as Figure 1As shown in the figure, the wire harness carrier 1 is used for clamping a multi-core wire, and the wire harness carrier 1 is configured to arrange the cores of the multi-core wire in parallel at intervals; in an embodiment of the present invention, the wire harness carrier 1 is used for clamping a wire harness, and arranges multiple cores of the multi-core wire at intervals in the horizontal direction. It should be noted here that the insulating skin outside the core has been stripped in the previous process, and the horizontal arrangement of the cores is also processed in the previous process. There are various specific horizontal arrangement methods. For example, the multiple core wires can be temporarily fixed by clamping with two horizontal clamping plates, or the interval arrangement of the cores can be achieved through multiple spaced holes, etc. Those skilled in the art can select and implement according to needs.

[0024] The moving crimping mechanism 2 includes a bracket 21, a first crimping component 22 and a second crimping component 23 which are oppositely arranged on the bracket 21. The first crimping component 22 and the second crimping component 23 can move relatively closer to achieve crimping. It further includes a material pushing component 24 fixed on the second crimping component 23 and a driving mechanism 25 for driving the movement of the bracket 21; it should be noted here that in an embodiment of the present invention, the driving mechanism 25 is used to drive the movement of the bracket 21. Since both the first crimping component 22 and the second crimping component 23 are connected to the bracket 21, the first crimping component 22 and the second component both move synchronously with the bracket 21. Moreover, the material pushing component 24 is also fixed on the second crimping component 23, so that when the driving mechanism 25 drives the bracket 21 to move, it can drive the material pushing component 24 of the whole set of terminals and the first crimping component 22 and the second crimping component 23 to move synchronously, thereby forming a process of sequentially moving and crimping the ends of multiple core wires. Of course, it should be noted here that there are various forms of the driving mechanism 25. For example, it can be achieved by a lead screw structure or other existing driving forms.

[0025] In an embodiment of the present invention, the drive mechanism 25 drives the bracket 21 to drive the first crimping assembly 22 and the second crimping assembly 23 to move to each core wire end for crimping, and the material shifting assembly 24 shifts the material strip once after each crimping, so that the terminal follows the crimping seat 232 assembly to move to the core wire end to be crimped. Of course, it should be pointed out here that when the crimping operation is performed, the movement of the terminal and the movement of the bracket 21 can be performed synchronously, that is, when the bracket 21 moves, the terminal has moved to the second crimping assembly 23, and the movement of the bracket 21 makes the terminal placed on the second crimping assembly 23 aligned with the end of the core wire to be crimped, and then the first crimping assembly 22 and the second crimping assembly 23 are close to each other to achieve crimping. The specific terminal crimping is a prior art and will be described in detail below. In an embodiment of the present invention, the terminal can be a terminal with an upper opening or a terminal with an end opening. Through such a setting, the mobile crimping mechanism 2 can continuously crimp the terminals of multiple core wires without the wiring harness moving.

[0026] In the above embodiment, the wire harness is clamped on the wire harness carrier 1, and the first crimping assembly 22, the second crimping assembly 23 and the material shifting assembly 24 are synchronously moved to the core wire end by moving the bracket 21. The crimping of the terminal is achieved by the mutual proximity of the first crimping assembly 22 and the second crimping assembly 23. Compared with the prior art, the crimping of the terminals of multiple core wires is achieved without moving the wire harness, thereby improving the efficiency of crimping.

[0027] Based on the above embodiments, Figure 2 As shown in the figure, in an embodiment of the present invention, a wire harness carrier 1 has a wire harness clamp 11 for clamping the wire harness and a wire separation claw 12 provided at the end of the wire harness. The wire separation claw 12 is used to space the core wires of a multi-core wire. The wire harness clamping function is to fix the wire harness and prevent it from moving during the crimping process. In the embodiment of the present invention, the wire harness clamping has various structural forms, such as a conventional clamping claw cylinder, and other clamping structures can also be used.

[0028] For the structure of the wire separation claw 12, please refer to Figure 3 In an embodiment of the present invention, the wire separation claw 12 has a plurality of vertical comb teeth 121 arranged in parallel and spaced apart, and each core wire is confined between two adjacent vertical comb teeth 121. The structural form of the plurality of vertical comb teeth allows a width between adjacent comb teeth to accommodate a single core wire. When fixing, the plurality of core wires are sequentially pressed into the gap between the two vertical comb teeth 121. In an embodiment of the present invention, the plurality of vertical comb teeth 121 have the same height. This structural form allows the plurality of core wires to be spaced apart and on the same horizontal plane when the core wire is pressed into the bottom of the gap between the two vertical comb teeth 121, thereby providing a good foundation for subsequent terminal crimping.

[0029] In an embodiment of the present invention, there are multiple wire harness carriers 1, which are configured on a circulating line. It should be noted here that the circulating line is a prior art, such as the automated equipment circulating device disclosed in the invention patent with the publication number CN111252490B. In the embodiment of the present invention, multiple carriers can be provided and arranged at intervals on the circulating line, so that after the wire harness crimping on one wire harness carrier 1 is completed, the crimping operation of the core wire on the next wire harness carrier 1 can be carried out, thereby further improving the crimping efficiency of the wire core.

[0030] Regarding the specific structures of the first crimping component 22 and the second crimping component 23 as Figure 4 shown in, in some embodiments of the present invention, the first crimping component 22 includes a first slide rail 221, a crimping head 222 slidably connected to the first slide rail 221, and a first crimping drive component 223 for driving the lifting of the crimping head 222; the first slide rail 221 is vertically arranged, so that the crimping head 222 can slide up and down in the vertical direction on the first slide rail 221. The structural form of the first slide rail 221 has various forms, which can be in the form of a track or can form a structural form of a chute as Figure 4 shown in. Regarding the structural form of the crimping head 222 as Figure 6 shown in, a downwardly opening groove is formed at the bottom of the crimping head 222, and the groove matches the outer surface of the terminal when it is closed. Then, by pressing down the crimping head 222, the open terminal is closed or the diameter of the terminal is compressed to achieve reliable fixation of the bare end of the core wire.

[0031] Please continue to refer to Figure 4 , in the embodiment of the present invention, the second crimping component 23 includes a second slide rail 231, a crimping seat 232 slidably connected to the second slide rail 231, and a second crimping drive component 233 for driving the lifting of the crimping seat 232; the structural form of the second slide rail 231 is similar to that of the first slide rail 221, and will not be elaborated here. The structural form of the crimping seat 232 is as Figure 6As shown in the figure, the top of the crimping base 232 has a groove with an upward opening, which can be used for positioning the terminal. Through cooperation with the groove with a downward opening on the crimping head 222, crimping of the terminal can be achieved. The crimping base 232 and the crimping head 222 are arranged opposite to each other, and the feeding component 24 conveys the terminal to be crimped onto the crimping base 232. Here, the structural forms of the first crimping drive component 223 and the second crimping drive component 233 are the same. There are various specific drive forms. For example, a conventional air cylinder can be used for driving, or it can be achieved through a lead screw structure, etc. In addition, it should be noted here that in the embodiment of the present invention, the first crimping component 22 and the second crimping component 23 can be fixed by a structural form of fixing the drive component on the bracket 21. The crimping head 222 and the crimping base 232 can move up and down under the drive of the drive component to achieve the crimping operation.

[0032] In some embodiments of the present invention, since different terminals require different degrees of crimping, in order to meet different degrees of crimping requirements, as Figure 5 As shown in the figure, both the first crimping drive component 223 and the second crimping drive component 233 include: a motor 2331, a speed reducer 2332 connected to the motor 2331, and a slider 2333 eccentrically rotatably connected to the output end of the speed reducer 2332. The slider 2333 is horizontally slidably connected to the crimping head 222 or the crimping base 232. Here, "or" means that the slider 2333 on the first crimping component 22 is slidably connected to the crimping head 222, and the slider 2333 on the second crimping component 23 is slidably connected to the crimping base 232. Through the eccentric connection of the slider 2333, there is a height change in the height of the slider 2333 when it rotates. Furthermore, through the horizontal sliding connection with the crimping head 222 or the crimping base 232, in cooperation with the up and down sliding connection of the crimping head 222 and the first slide rail 221, and the up and down sliding connection of the crimping base 232 and the second slide rail 231, when the motor 2331 drives the speed reducer 2332 to rotate, the slider 2333 at the output end of the speed reducer 2332 drives the crimping head 222 or the crimping base 232 to move up and down while making a circular motion. Therefore, different rotation angles of the speed reducer 2332 can achieve different approaching distances between the crimping base 232 and the crimping head 222, thus meeting different crimping distances.

[0033] As Figure 6As shown in , the material-dispensing assembly 24 includes a feeding platform 241 fixed on the crimping seat 232, and the feeding platform 241 is used to transport the terminal to the crimping seat 232. The material-dispensing assembly 24 also includes a dial pin 242 for moving the material strip and a dial driving member that drives the dial pin 242 to move; the material-dispensing assembly 24 is a prior art, and the swing driving member 243 drives the dial pin 242 to swing, and the dial pin 242 moves forward a set distance, which can drive the movement of the material strip. The specific wave driving member 243 can be a cylinder, or it can be a rotation of the motor 2331 to drive the reciprocating movement of the dial pin 242; in addition, in the embodiment of the present invention, since the material-dispensing assembly 24 moves with the bracket 21, in order to further improve the accuracy of the docking between the crimping head 222 and the crimping seat 232, as shown in Figure 6 As shown in FIG, the feeding platform 241 further has a third slide rail 244, and the crimping head 222 is slidably connected to the third slide rail 244. It should be noted here that the structure of the third slide rail 244 can be fixed to the edge of the feeding platform 241 and extend upward, which can be as follows Figure 6 The structural form of the slide formed as shown in the figure can also be a track form and slidably connected to the crimping head 222. Through the setting of this structural form, on the one hand, the reliability of the material belt transmission can be improved and the shaking of the material belt during the transportation process can be reduced. On the other hand, the alignment accuracy of the crimping head 222 and the crimping seat 232 can also be improved.

[0034] In the embodiment of the present invention, the specific structure of the driving mechanism 25 for driving the bracket 21 to move is as follows: Figure 7 and Figure 8 As shown in , the driving mechanism 25 is a cross drive, including a first drive 251 parallel to the feeding direction of the terminal material strip and a second drive 252 connected to the driving end of the first drive 251 and perpendicular to the driving direction of the first drive 251, and the bracket 21 is fixed to the driving end of the second drive 252. The first drive 251 here can drive the rotation of the screw by the motor, and the screw is screwed on the nut seat, and the nut seat is slidably connected to the slide rail; the second drive 252 is fixed on the nut seat, and the screw of the second drive 252 is arranged in a vertical form to the screw on the first drive 251, so that the driving directions of the first drive 251 and the second drive 252 are perpendicular, forming a cross-shaped driving structure. The bracket 21 is fixed on the nut seat of the second drive 252. Through the setting of this structural form, the bracket 21 can move left and right as well as forward and backward. The left and right movement here refers to movement along the moving direction of the material strip, and the forward and backward movement refers to movement along the axial direction of the wire harness. Through the setting of this structural form, as shown in FIG. Figure 3 After the four core wires shown in the figure are arranged horizontally, the lengths of the core wires on both sides are slightly shorter than the two core wires in the middle. The terminals can be placed in the correct position by moving the bracket 21 back and forth, thereby ensuring the reliability of the transfer crimping.

[0035] Please continue to refer to Figure 7 and Figure 9 In the embodiment of the present invention, the moving crimping mechanism 2 further includes a tape feeding assembly 26 for feeding a tape with terminals towards the material feeding assembly 24. The tape feeding assembly 26 is fixed on the bracket 21 and can move together with the bracket 21, thereby reducing the shaking and pulling of the tape during the tape unwinding process. In the embodiment of the present invention, the tape feeding assembly 26 includes a tape feeding reel 261, a first receiving groove 262 arranged towards the tape feeding reel 261, and a second receiving groove 263 arranged towards the end of the first receiving groove 262. There is a gap between the second receiving groove 263 and the first receiving groove 262, and a tape break detection assembly 264 is arranged between the first receiving groove 262 and the second receiving groove 263. The tape break detection assembly 264 determines whether there is a tape between the two by detecting whether the first receiving groove 262 and the second receiving groove 263 are electrically connected. In the embodiment of the present invention, the first receiving groove 262 is L-shaped, enabling the tape released from the tape feeding reel 261 to smoothly transition. The corner of the L-shaped first receiving groove 262 is arc-shaped, enabling the tape to remain in contact with the distal end of the first receiving groove 262. The distal end is the end far from the tape feeding reel 261. Then the tape remains in contact with the second receiving tray, and then the tape enters the crimping position through the above-mentioned material feeding platform 241. During this process, the tape remains in contact with both the first receiving groove 262 and the second receiving groove 263. In the embodiment of the present invention, in order to detect whether the tape has been completely released, at least the opposite ends of the above-mentioned first receiving groove 262 and the second receiving groove 263 are made of conductive material. Since the tape is made of metal material, it can conduct electricity. The tape break detection assembly 264 can be a circuit structure arranged between the first receiving groove 262 and the second receiving groove 263, and determines whether the tape is simultaneously lapped on the first receiving groove 262 and the second receiving groove 263 by judging whether the first receiving groove 262 and the second receiving groove 263 are electrically connected. When it is detected that the electricity between the two is not conducted, it means that the end of the tape has moved from the first receiving groove 262 to the second receiving groove 263, or the tape has broken. The function of tape break detection is realized through the above structural form. Of course, it should be noted here that in the embodiment of the present invention, the material feeding assembly 24 also has a blowing air pipe and a waste collection mechanism to improve the smoothness of crimping.

[0036] In the embodiment of the present application, a crimping method for the above multi-core wire terminal crimping machine is also provided. As Figure 10 shown in S10: Move the wire harness carrier 1 to the crimping position of the moving crimping mechanism 2; S20: Drive the material shifting assembly 24 to move the terminal to be crimped onto the crimping seat 232, and move the bracket 21 so that the crimping seat 232 is at the position of the first core wire; it should be pointed out here that in an embodiment of the present invention, the action of shifting the terminal can be completed in the process of moving the bracket 21 to achieve further speed increase.

[0037] S30: driving the crimping head 222 and the crimping seat 232 to approach each other to achieve crimping of the first core wire; it should be noted here that in the embodiment of the present invention, the first core wire refers to the outermost core wire along the moving direction of the terminal strip, for example, if the terminal moves toward the right, the first core wire refers to the rightmost core wire; S40: Drive the material shifting assembly 24 to move the terminal to be crimped onto the crimping seat 232, and move the bracket 21 so that the crimping seat 232 is located at the position of the next core wire; during the crimping process, the terminal will be separated from the material strip, so it will not affect the crimping of the next terminal.

[0038] S50: driving the crimping head 222 and the crimping seat 232 to move closer to each other to crimp the next core wire; S60: Repeat steps S40 and S50 until the multi-core wire crimping is complete. This reciprocating process allows for the crimping of multiple wires. Furthermore, the harness carrier 1 can hold multiple wires in parallel, allowing the next one to be processed after one harness is processed. After processing one harness on a harness carrier 1, the next carrier is moved to the mobile crimping mechanism 2 via a loop line. This significantly improves the efficiency of the multi-core wire crimping process.
