Description

Technical Field

[0001] This invention belongs to the technical field of automotive wiring harness material cutting and feeding equipment, and particularly relates to an automotive wiring harness crimping cutting and feeding equipment and its manufacturing process. Background Technology

[0002] Automotive wiring harness crimping cutting and feeding equipment is a core automated device that realizes automatic supply, precise positioning and conveying of materials such as terminals, wires and sheaths. Its core function is to replace manual feeding and improve crimping efficiency, consistency and yield.

[0003] In related technologies, refer to Figure 1 The automotive wiring harness terminal 14 is connected and positioned on the material strip 13, which is wound into the material reel 1. During the feeding process of the wiring harness terminal 14, the material strip 13 is pulled to the feeding separation device position by the conveyor line, and the wiring harness terminal 14 is cut off from the material strip 13 by the shearing mechanism. Then, it is installed into the connector by the robot arm. (Refer to...) Figure 2 A groove is provided at the connection between the wire harness terminal 14 and the material strip 13. The material strip 13 passes vertically through the feeding and separating device. The feeding and separating device is equipped with clamping robots 11 on both sides of the material strip, and a shearing block 12 is provided in the middle of the two clamping robots 11. The shearing block 12 is set against the side of the groove between the material strip 13 and the wire harness terminal 14. During feeding, the two clamping robots 11 move closer to each other. Each clamping robot 11 first attaches to both sides of the material strip 13 with the shearing block 12. As the clamping robots 11 move, the clamping robots 11 and the shearing block 12 form a shearing force on the groove, cutting the groove so that the wire harness terminal 14 is separated from the material strip 13. Then, the two clamping robots 11 clamp the wire harness terminal 14 for feeding and installation.

[0004] However, in the above process, the clamping robot 11 and the shearing block 12 need to form a shearing force on the broken groove, which requires the clamping robot 11 and the shearing block 12 to be in close contact to avoid bending the broken groove instead of shearing it. However, this will cause the clamping robot 11 to rub against the end face of the shearing block 12 when it shears and continues to move, thereby generating static electricity. At the same time, burrs will also be generated after the broken groove is cut. As the above process continues, the burrs on the clamping robot 11 will accumulate more and more, and some burrs will be pressed into the outer wall of the cut wire harness terminal 14 by the clamping robot 11, forming a dent or contaminating the contact surface. As a result, after the wire harness terminal 14 is installed to the connector, it will affect the subsequent electroplating or welding performance.

[0005] Therefore, it is urgent to design a cutting and feeding device and its production process for automotive wiring harness crimping to solve the technical problem in the above process where the clamping robot 11 and the shearing block 12 shear and rub against each other, generating static electricity, and the burrs cut by the slot are attracted to the clamping robot 11 due to static electricity, causing the clamping robot 11 to press the burrs into the outer wall of the subsequent wiring harness terminal 14.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0007] This disclosure provides at least one cutting and feeding device for automotive wiring harness crimping and its manufacturing process.

[0008] In a first aspect, the present disclosure provides a cutting and feeding device for automotive wiring harness crimping, comprising: a material rail, the interior of which is adapted to convey a material belt, and a plurality of terminals are equally spaced on the material belt; The loading gripper and the cutting gripper are slidably mounted on both sides of the material rail. The feed rail and the cutting gripper are respectively provided with a first cutting groove and a second cutting groove; Two cutting blocks are rotatably installed in the first cutting groove and the second cutting groove, respectively; The cutting block has a plurality of cutting blades along the circumferential direction; The two cutting blocks are arranged opposite each other on both sides of the material strip, and the side of the cutting block facing the material strip has a cutting station; The loading gripper is provided with a pusher block facing the cutting block; The top of the cutting block is provided with several magnetic posts, and one magnetic post corresponds to one cutting blade; Furthermore, during terminal loading, the loading gripper and the cutting gripper approach the material strip from opposite sides. The loading gripper pushes the magnetic column of the material rail with a pusher block, causing the cutting block of the material rail to rotate to the next cutting blade position. Then, the cutting block of the cutting gripper first abuts against the cutting block of the material rail on both sides of the material strip, and the terminal is cut off from the material rail by the cutting blades respectively. Then, the loading gripper pushes the magnetic column of the cutting gripper with a pusher block, causing the cutting block of the cutting gripper to rotate to the next cutting blade position.

[0009] In one optional embodiment, plasma air ducts are respectively provided inside the first cutting groove and the second cutting groove; The air outlets of the plasma air duct face the end faces of the two cutting blocks respectively.

[0010] In one alternative embodiment, the first and second cutting slots are further provided with a material discharge channel.

[0011] In one optional embodiment, the material discharge channel is located below the air outlet of the plasma air knife; The material pouring channel is located between the air outlet of the plasma air knife and the end face of the cutting block.

[0012] In one optional embodiment, a push rod is provided between the loading gripper and the push block, and the push block is rotatably mounted at the end of the push rod; The push rod end is provided with a guide groove; In addition, as the loading gripper approaches the cutting gripper, the push block abuts against the guide groove, so that the push block pushes the magnetic suction column and drives the cutting block to rotate; As the loading gripper moves away from the cutting gripper, the magnetic column pusher block rotates along the guide groove so that the pusher block passes over the magnetic column.

[0013] In one alternative implementation, the distance between the feed rail and the cutting gripper is greater than the maximum width of the push block.

[0014] In one optional embodiment, a plurality of electromagnetic suction heads are provided inside the first and second cutting grooves; The electromagnetic suction head corresponds to the magnetic suction column.

[0015] In one optional embodiment, the loading gripper has a positioning groove on the side facing the strip, and the positioning groove corresponds to the terminal; Additionally, after the two cutting blocks cut the terminals from the strip, the terminals are locked in the positioning groove, and the loading claws and cutting claws hold the positioning terminals from both sides.

[0016] In one optional embodiment, the cutting and feeding device further includes a drive motor, the movable end of which is equipped with a drive disk, and the outer wall of the drive disk is provided with a number of protrusions at equal intervals along the circumference. The strip is provided with several through holes at equal intervals, and the through holes correspond to the protrusions.

[0017] Secondly, this disclosure also provides a production process, characterized in that it is applied to the automotive wiring harness crimping cutting and feeding equipment described above, and the production process includes the following steps: Step S1: Install the material strip on the material rail and convey it along the material rail to between the loading gripper and the cutting gripper, so that the side of the terminal to be unloaded is attached to the cutting block located on the material rail; In step S2, the material rail and the cutting gripper are respectively positioned by magnetic attraction of the magnetic column to the corresponding cutting block. At the same time, the loading gripper and the cutting gripper approach the material strip from opposite directions. Step S3: The loading gripper pushes the magnetic column of the material rail through the push block, so that the cutting block of the material rail rotates to the next cutting blade located at the cutting station; Step S4: The cutting block of the cutting jaw first abuts against the cutting block of the material rail on both sides of the material strip, and the terminal is cut off from the material rail by the cutting blades respectively. Step S5: The loading gripper pushes the magnetic suction column of the cutting gripper by the push block, so that the cutting block of the cutting gripper rotates to the next cutting blade position at the cutting station; Step S6: The loading jaws and the cutting jaws clamp the cut terminals from both sides.

[0018] The beneficial effect of the present invention is that by setting a cutting block with multiple cutting blades and capable of rotation on the feed rail and the cutting gripper, and after the two cutting blocks cut the terminal from the feed strip, the cutting block is pushed to rotate by the push block on the loading gripper so that the next cutting blade on each cutting block along the rotation direction is opposite to each other, thus avoiding the adsorption of the sheared debris on the cutting edge due to frictional static electricity and pressing it into the outer wall of the terminal.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Research has found that, in related technologies, reference Figure 1 The automotive wiring harness terminal 14 is connected and positioned on the material strip 13, which is wound into the material reel 1. During the feeding process of the wiring harness terminal 14, the material strip 13 is pulled to the feeding separation device position by the conveyor line, and the wiring harness terminal 14 is cut off from the material strip 13 by the shearing mechanism. Then, it is installed into the connector by the robot arm. (Refer to...) Figure 2A groove is provided at the connection between the wire harness terminal 14 and the material strip 13. The material strip 13 passes vertically through the feeding and separating device. The feeding and separating device is equipped with clamping robots 11 on both sides of the material strip, and a shearing block 12 is provided in the middle of the two clamping robots 11. The shearing block 12 is set against the side of the groove between the material strip 13 and the wire harness terminal 14. During feeding, the two clamping robots 11 move closer to each other. Each clamping robot 11 first attaches to both sides of the material strip 13 with the shearing block 12. As the clamping robots 11 move, the clamping robots 11 and the shearing block 12 form a shearing force on the groove, cutting the groove so that the wire harness terminal 14 is separated from the material strip 13. Then, the two clamping robots 11 clamp the wire harness terminal 14 for feeding and installation.

[0026] However, in the above process, the clamping robot 11 and the shearing block 12 need to form a shearing force on the broken groove, which requires the clamping robot 11 and the shearing block 12 to be in close contact to avoid bending the broken groove instead of shearing it. However, this will cause the clamping robot 11 to rub against the end face of the shearing block 12 when it shears and continues to move, thereby generating static electricity. At the same time, burrs will also be generated after the broken groove is cut. As the above process continues, the burrs on the clamping robot 11 will accumulate more and more, and some burrs will be pressed into the outer wall of the cut wire harness terminal 14 by the clamping robot 11, forming a dent or contaminating the contact surface. As a result, after the wire harness terminal 14 is installed to the connector, it will affect the subsequent electroplating or welding performance.

[0027] Therefore, it is urgent to design a cutting and feeding device and its production process for automotive wiring harness crimping to solve the technical problem in the above process where the clamping robot 11 and the shearing block 12 shear and rub against each other, generating static electricity, and the burrs cut by the slot are attracted to the clamping robot 11 due to static electricity, causing the clamping robot 11 to press the burrs into the outer wall of the subsequent wiring harness terminal 14.

[0028] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure below should be considered as the inventor's contribution to this disclosure.

[0029] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the embodiments and features described below can be combined with each other. Furthermore, in the accompanying drawings, the thickness of components may be exaggerated or reduced for the purpose of effectively describing the technical content.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] Based on the above research, and referring to Figure 3 This disclosure provides a cutting and feeding device for automotive wiring harness crimping, comprising: a device frame, on which a material rail 2, a loading gripper 3, a cutting gripper 4, and a feeding robot 8 are mounted. The material rail 2 is internally adapted to convey a material strip, on which a plurality of terminals are evenly spaced. The loading gripper 3 and the cutting gripper 4 are slidably disposed on both sides of the material rail 2. To facilitate material strip conveying and unloading, the material rail 2 is arranged vertically so that the material strip and terminals pass vertically through the loading gripper 3 and the cutting gripper 4. The loading gripper 3 and the cutting gripper 4 are arranged horizontally so that the cutting gripper 4 can cooperate with the material rail 2 to cut the terminals from the material strip horizontally.

[0032] Reference Figure 4 and Figure 8 In at least one embodiment, the loading gripper 3 has a positioning groove 32 on the side facing the material strip, and the shape and size of the positioning groove 32 match the corresponding position of the terminal. After the two cutting blocks 5 cut the terminal from the material strip, the terminal is locked in the positioning groove 32 to prevent the terminal from falling. Then, as the loading gripper 3 and the cutting gripper 4 continue to approach, the loading gripper 3 and the cutting gripper 4 clamp the positioning terminal from both sides.

[0033] Reference Figure 4 In some embodiments, the loading gripper 3 has a positioning groove 32 on the side facing the material strip, and the positioning groove 32 corresponds to the terminal. After the two cutting blocks 5 cut the terminal from the material strip, the terminal is locked in the positioning groove 32, and the loading gripper 3 and the cutting gripper 4 hold the positioning terminal from both sides.

[0034] Reference Figure 3 The loading robot 8 is installed on the outside of the material rail 2, and its movable end is set vertically. Two sets of horizontal drive mechanisms are also installed on the equipment frame. Each horizontal drive mechanism includes a first horizontal cylinder and a second horizontal cylinder. The first horizontal cylinder is fixedly installed on the equipment frame, and the second horizontal cylinder is installed on the movable end of the first horizontal cylinder. The loading gripper 3 and the cutting gripper 4 are respectively installed on the movable ends of the two second horizontal cylinders. Figure 3For example, the second horizontal cylinder is vertically arranged with the first horizontal cylinder. The first horizontal cylinder is suitable for driving the second horizontal cylinder, as well as the loading gripper 3 and the cutting gripper 4, to slide inward and outward. The second horizontal cylinder is suitable for driving the loading gripper 3 and the cutting gripper 4 to slide horizontally left and right. The function of the above structure is that, when cutting the terminal, the second horizontal cylinder is used as a power source to drive the loading gripper 3 and the cutting gripper 4 to move closer together. After cutting the terminal, the terminal is clamped. Then, while maintaining the clamped state, the first horizontal cylinder is used as a power source to drive the loading gripper 3 and the cutting gripper 4 to slide outward until they are below the loading robot 8. Then, the loading robot 8 descends to allow the terminal to be inserted into the loading robot 8. Then, the loading gripper 3 and the cutting gripper 4 release the terminal, and the loading robot 8 inserts the terminal into the connector and fixes it. Based on the above actions, a reverse motion process can be further designed to drive the loading robot 8, the loading gripper 3, and the cutting gripper 4 to reset and start the next work cycle.

[0035] Reference Figure 4 , Figure 5 and Figure 6 In at least one embodiment, the feed rail 2 and the cutting gripper 4 are respectively provided with a first cutting groove 21 and a second cutting groove 41, and two cutting blocks 5 are rotatably installed in the first cutting groove 21 and the second cutting groove 41 respectively. The cutting blocks 5 have a plurality of cutting blades 51 along the circumferential direction, and the two cutting blocks 5 are respectively located on both sides of the feed strip. By the cutting blades 51 of the two cutting blocks 5 being tightly fitted and aligned on both sides of the terminal, the two cutting blades 51 exert a shearing force on the feed strip to cut the terminal rather than bend it. Therefore, the position of the two cutting blocks 5 suitable for cutting the terminal forms a cutting station. When any cutting blade 51 of the cutting block 5 rotates to the cutting station, the terminal can be cut by that cutting blade 51.

[0036] Reference Figure 4 and Figure 6 Based on the above design, by setting multiple cutting blades 51 on the cutting block 5 and making the cutting block 5 a rotatable structure, after each cutting of the terminal, the next terminal can be replaced along the rotation direction for subsequent cutting, effectively avoiding the accumulation of cutting debris caused by static electricity and preventing debris from being pressed into the outer wall of the terminal. Furthermore, based on the above design, the cutting block 5 is designed as a regular polygonal prism structure to ensure that the distance between each blade edge and the rotation center is equal, adapting to the position of the cutting station. In some embodiments, preferably, the cutting block 5 is designed as a regular square prism. Therefore, the first cutting groove 21 and the second cutting groove 41 are also designed as arc-shaped grooves. Taking the first cutting groove 21 as an example, after the cutting block 5 has rotated and settled, the two edges of the cutting block 5 are located at the two ends of the first cutting groove 21, and one side of the cutting block 5 faces the inside of the first cutting groove 21, at which time a relatively closed space is formed inside the first cutting groove 21.

[0037] Reference Figure 6 and Figure 7 In at least one embodiment, plasma air ducts 6 are respectively provided inside the first cutting groove 21 and the second cutting groove 41. The air outlets of the plasma air ducts 6 are respectively directed towards the end faces of the two cutting blocks 5. The plasma air blows onto the end faces of the cutting blocks 5 located inside the first cutting groove 21 and the second cutting groove 41 to remove static electricity from these end faces. Simultaneously, the first cutting groove 21 and the second cutting groove 41 are also provided with a material discharge channel 61. The material discharge channel 61 is located below the air outlet of the plasma air knife and between the air outlet of the plasma air knife and the end face of the cutting block 5. The plasma air is discharged through the material discharge channel 61, blowing debris from the cutting edge 51 into the material discharge channel 61, thereby removing static electricity and debris from the cutting blocks 5 and ensuring that the cutting edge 51 remains clean and free of debris during subsequent cutting processes.

[0038] Reference Figure 8 and Figure 9 In at least one embodiment, the loading gripper 3 is provided with a push rod 33 facing the cutting block 5, and a push block 31 is rotatably provided at the end of the push rod 33, i.e., the end away from the loading gripper 3. Meanwhile, a plurality of magnetic suction posts 52 are provided on the top of the cutting block 5, with one magnetic suction post 52 corresponding to one cutting blade 51. As the loading gripper 3 approaches the cutting gripper 4, the push block 31 can push the magnetic suction posts 52 to rotate the cutting block 5, causing the next cutting blade 51 to rotate to the cutting position, thereby achieving the effect of switching cutting blades 51. Furthermore, a guide groove 34 is provided at the end of the push rod 33. As the loading gripper 3 moves away from the cutting gripper 4, the magnetic suction posts 52 push the push block 31 to rotate along the guide groove 34, causing the push block 31 to pass over the magnetic suction posts 52. With the above settings, when the loading gripper 3 retracts, the pusher 31 can avoid the magnetic suction column 52 by rotating along the guide groove 34, thus preventing the top pusher cutting block 5 from rotating in the opposite direction.

[0039] Reference Figure 5 The above process can be summarized as follows: When the terminal is being fed, the loading gripper 3 and the cutting gripper 4 approach the material strip from opposite directions. The loading gripper 3 moves along the material strip via the pusher block 31. f 1. The magnetic suction column 52 of the pusher rail 2 is pushed in one direction so that the cutting block 5 of the pusher rail 2 moves along the magnetic suction column 52. f The device rotates in direction 2 until the next cutting blade 51 is positioned at the cutting station. Then, the cutting block 5 of the cutting gripper 4 first abuts against the cutting block 5 of the material rail 2 on both sides of the material strip, and the terminals are cut off from the material rail 2 by the cutting blade 51. Next, the loading gripper 3 pushes the magnetic suction column 52 of the cutting gripper 4 by the push block 31, so that the cutting block 5 of the cutting gripper 4 moves along... f Rotate in 3 directions to the next cutting blade 51 located at the cutting station.

[0040] Reference Figure 7In at least one embodiment, it should be noted that, since cutting the terminals requires ensuring the direction of the shearing force, the two cutting blocks 5 need to be positioned during the cutting process. The first cutting groove 21 and the second cutting groove 41 are equipped with several electromagnetic suction heads 62, which correspond to the magnetic suction columns 52. When the cutting block 5 is stationary, the electromagnetic suction heads 62 can be energized to generate magnetic force, thereby attracting the magnetic suction columns 52, thus keeping the cutting block 5 positioned by electromagnetic force. Conversely, when the electromagnetic suction heads 62 are de-energized, the cutting block 5 can be released, allowing it to rotate. On the other hand, when the push block 31 pushes the magnetic suction column 52, it causes the cutting block 5 to rotate beyond the theoretical angle. Through the magnetic attraction between the electromagnetic suction heads 62 and the magnetic suction column 52, the cutting block 5 can be driven to rotate, ensuring that the cutting blade 51 coincides with the cutting position and is positioned.

[0041] In some embodiments, in order to ensure that the push block 31 passes normally through the material rail 2 and the cutting claw 4, the distance between the material rail 2 and the cutting claw 4 is greater than the maximum width of the push block 31.

[0042] Reference Figure 3 In at least one embodiment, to ensure proper conveying of the material strip, the cutting and feeding device further includes a drive motor 7. A drive disk 71 is mounted on the movable end of the drive motor 7. The outer wall of the drive disk 71 has a plurality of protrusions 72 evenly spaced along its circumference. The material strip has a plurality of through holes evenly spaced, corresponding to the protrusions 72. The drive motor 7 inserts into the through holes through the protrusions 72 on the drive disk 71 to push and convey the material strip, while ensuring that the stepping distance of the material strip is consistent with the spacing of the protrusions 72, thereby ensuring that the terminal moves correctly to one side of the cutting block 5.

[0043] Furthermore, this disclosure also provides a manufacturing process for use in the automotive wiring harness crimping cutting and feeding equipment described above, the manufacturing process comprising the following steps: Step S1: Install the material strip on the material rail 2 and convey it along the material rail 2 to between the loading gripper 3 and the cutting gripper 4, so that the side of the terminal to be unloaded is attached to the cutting block 5 located on the material rail 2. In step S2, the loading gripper 3 and the cutting gripper 4 approach the material belt from opposite directions. The material rail 2 releases the corresponding cutting block 5. The loading gripper 3 pushes the magnetic column 52 of the material rail 2 through the push block 31 so that the cutting block 5 of the material rail 2 rotates to the next cutting blade 51 located at the cutting station. In step S3, the material rail 2 and the cutting gripper 4 respectively use magnetic suction column 52 to magnetically position the corresponding cutting block 5; In step S4, the cutting block 5 of the cutting claw 4 first abuts against the cutting block 5 of the material rail 2 on both sides of the material strip, and the terminal is cut off from the material rail 2 by the cutting blade 51 respectively. Step S5: The cutting gripper 4 releases the corresponding cutting block 5, and the loading gripper 3 pushes the magnetic suction column 52 of the cutting gripper 4 through the push block 31 so that the cutting block 5 of the cutting gripper 4 rotates to the next cutting blade 51 located at the cutting station. Step S6: The loading gripper 3 and the cutting gripper 4 clamp the cut terminals from both sides and then unload them.
