Description

Technical Field

[0001] This utility model relates to the field of wire processing technology, and specifically to a winding mechanism for a wire double-ended terminal crimping and numbering tube insertion machine. Background Technology

[0002] In the field of wire harness manufacturing, traditional wire marking mainly relies on manual insertion of number tubes or pasting of labels, which suffers from common industry problems such as low efficiency (the average daily processing capacity of a single worker is less than 500 wires), easy detachment of labels, and non-standard orientation. With the increasing requirements for wire harness integration in automotive electronics and intelligent equipment, existing technologies have exposed three major pain points: (1) the copper wire damage rate caused by manual tube insertion is as high as 3%-5%, affecting conductivity; (2) the separation of the number tube and terminal crimping process increases the secondary positioning error; (3) the marking content is limited by pre-printed characters and cannot adapt to the needs of flexible production. Current industry solutions mostly adopt semi-automatic tube insertion equipment, which can achieve basic positioning functions, but there are still bottlenecks in key technical links such as double-end synchronous processing and visual correction, making it difficult to meet the production capacity requirements of more than 2,100 wire harnesses per hour in the automotive industry. In recent years, fully automated number tube insertion systems that integrate servo crimping, CCD inspection, and laser marking technologies have become increasingly popular. Through process integration (integrated wire cutting, tube insertion, crimping, and inspection) and digital management (MES system traceability), they are driving the transformation of wire harness manufacturing towards a "zero-defect" production model.

[0003] For example, Chinese utility model patent CN 210467442 U discloses a number tube threading machine, including a wire clamping device for clamping the wire, a cutting device for cutting the number tube, a number tube supply device for supplying the number tube to the cutting device, a gripper device for clamping the number tube, and a transfer device for moving the gripper device between the wire clamping device and the cutting device. This utility model provides a number tube threading machine that, through the combined design of the wire clamping device, cutting device, number tube supply device, gripper device, and transfer device, can thread the number tube onto the wire, thus eliminating the need for manual threading by operators, reducing workload, saving time, and improving efficiency, thereby facilitating widespread adoption.

[0004] However, as various industries become increasingly intelligent, the types and quantities of wires required are increasing. The numbering tube threading machine disclosed in the above patent has a low degree of automation and cannot achieve double-head terminal crimping, resulting in low production efficiency and inability to meet market demand.

[0005] In view of the above, the inventors propose the following technical solution. Summary of the Invention

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a winding mechanism for a wire double-ended terminal crimping and number tube threading machine.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a winding mechanism for a wire double-ended terminal crimping and number tube threading machine, comprising: a support frame, an upper tape roll and a lower tape roll disposed on the support frame, a fixed adhesive plate and a movable adhesive plate disposed between the upper tape roll and the lower tape roll for attaching the tape to both sides of the wire, a fourth lifting cylinder disposed below the movable adhesive plate, an upper guide wheel disposed between the upper tape roll and the fixed adhesive plate for transmitting the upper tape, a plurality of lower guide wheels disposed around the fourth lifting cylinder for transmitting the lower tape, a winding drive device disposed on one side of the fixed adhesive plate and the movable adhesive plate for pulling the upper tape and the lower tape out, and a transport gripper disposed on the support frame for gripping the wire and moving it between the fixed adhesive plate and the movable adhesive plate, wherein the transport gripper is provided with two grippers to grip both ends of the wire.

[0008] Furthermore, in the above technical solution, the handling gripper includes a second guide rail disposed above the fixed adhesive plate, a second movable seat slidably disposed on the second guide rail, a fifth gripper and a sixth gripper disposed at intervals and parallel on the second movable seat, a transmission pulley assembly disposed on one side of the second guide rail, and a sixth motor for driving the transmission pulley assembly.

[0009] Furthermore, in the above technical solution, the roll drive device includes an upper pressure roller and a lower pressure roller disposed on one side of the fixed adhesive plate and the movable adhesive plate and cooperating to clamp the upper and lower adhesive tapes; an upper drive roller and a lower drive roller disposed on the support frame and used to support the upper pressure roller and the lower pressure roller; a reversing roller disposed beside the upper drive roller; a gear set disposed between the upper drive roller and the reversing roller and meshing with each other; a motor disposed on the support frame and used to drive the upper pressure roller and the lower pressure roller to rotate synchronously; and a transmission belt set disposed between the lower drive roller, the reversing roller, and the motor.

[0010] Furthermore, in the above technical solution, both the fixed adhesive plate and the movable adhesive plate have rounded chamfers at their front ends.

[0011] Furthermore, in the above technical solution, both the upper pressure roller and the lower pressure roller are fitted with elastic sleeves that allow the wire to pass through. The deformation of the elastic sleeves allows the wire to pass between the upper pressure roller and the lower pressure roller along with the upper and lower adhesive tapes.

[0012] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention uses a wire feeding mechanism to automatically feed out the wire, a number tube feeding mechanism to put the number tube onto the wire, a wire bending mechanism to bend the wire into a U-shape, a transfer module to clamp the two ends of the wire, and then the wire stripping mechanism and the terminal crimping mechanism to strip the wire ends and crimp the terminals. Finally, the winding mechanism connects the wires one by one into a roll of material. The whole process does not require manual intervention, has a high degree of automation, and greatly improves production efficiency. Attached Figure Description

[0032] The winding mechanism 7 includes a support frame 71 disposed at one end of the horizontal guide rail 11, an upper tape roll 72 and a lower tape roll 73 disposed on the support frame 71, a fixed adhesive plate 74 and a movable adhesive plate 75 disposed between the upper tape roll 72 and the lower tape roll 73 for attaching the tape to both sides of the wire, a fourth lifting cylinder 76 disposed below the movable adhesive plate 75, an upper guide wheel 77 disposed between the upper tape roll 72 and the fixed adhesive plate 74 for transmitting the upper tape, multiple lower guide wheels 78 disposed around the fourth lifting cylinder 76 for transmitting the lower tape, a winding drive device 79 disposed on one side of the fixed adhesive plate 74 and the movable adhesive plate 75 for pulling the upper and lower tapes out, and a transport gripper device 70 disposed on the support frame 71 for gripping the wire and moving it between the fixed adhesive plate 74 and the movable adhesive plate 75, wherein the transport gripper device 70 is provided with two grippers to grip both ends of the wire. The wire is picked up from the transfer module 1 by the handling gripper 70 and moved between the fixed adhesive plate 74 and the movable adhesive plate 75. The fourth lifting cylinder 76 pushes the movable adhesive plate 75 to rise and stick the upper and lower adhesive tapes to both sides of the wire. The upper and lower adhesive tapes are pulled away from the fixed adhesive plate 74 and the movable adhesive plate 75 by the winding drive device 79. This process is repeated to fix the main root of the wire to the upper and lower adhesive tapes and then roll it into a roll.

[0033] The transport gripper 70 includes a second guide rail 701 disposed above the fixed adhesive plate 74, a second movable seat 702 slidably disposed on the second guide rail 701, a fifth gripper 703 and a sixth gripper 704 disposed at intervals on the second movable seat 702, a transmission pulley assembly 705 disposed on one side of the second guide rail 701, and a sixth motor 706 for driving the transmission pulley assembly 705.

[0034] The roll drive device 79 includes an upper pressure roller 791 and a lower pressure roller 792 disposed on one side of the fixed adhesive plate 74 and the movable adhesive plate 75 and used to clamp the upper and lower adhesive tapes; an upper drive roller 793 and a lower drive roller 794 disposed on the support frame 71 and used to support the upper pressure roller 791 and the lower pressure roller 792; a reversing roller 795 disposed beside the upper drive roller 793; a gear set 796 disposed between the upper drive roller 793 and the reversing roller 795 and meshing with each other; a motor 797 disposed on the support frame 71 and used to drive the upper pressure roller 791 and the lower pressure roller 792 to rotate synchronously; and a transmission belt set 798 disposed between the lower drive roller 794, the reversing roller 795 and the motor 797.

[0035] Both the fixed adhesive plate 74 and the movable adhesive plate 75 have rounded chamfers at their front ends. By providing rounded chamfers at the front ends of the fixed adhesive plate 74 and the movable adhesive plate 75, it is possible not only to avoid tearing the upper and lower adhesive tapes, but also to facilitate the handling gripper 70 in gripping the wire and moving it between the fixed adhesive plate 74 and the movable adhesive plate 75.

[0036] Both the upper pressure roller 791 and the lower pressure roller 792 are fitted with elastic sleeves that allow the wire to pass through. The deformation of the elastic sleeves allows the wire to pass between the upper pressure roller 791 and the lower pressure roller 792 along with the upper and lower tapes.

[0037] In summary, during operation, the number printing device 21 pulls the number tube out of the number tube reel 25 and prints a preset label on it. Further, the transfer carrier device 22 extends the positioning pin 223 to the number tube printing device 21, and then the number tube printing device 21 fits the number tube onto the positioning pin 223. The clamping device 224 clamps the number tube, and the first cutting device 24 cuts the number tube. Further, the sleeve device 23 moves below the transfer carrier device 22 to receive the number tube. After the positioning pin 223 is pulled out of the number tube, the number tube is moved to the front end of the wire feeding mechanism 3. The wire feeding mechanism 3 and the sleeve device 23 insert the wire into the number tube, completing the number tube fitting. Further, the wire bending mechanism 4 clamps one end of the wire and bends it into a U-shape. Then, the first gripper 16 and the second gripper 18 on the transfer module 1 respectively grasp both ends of the wire. First, the wire is moved from the transfer module 1 to the wire stripping mechanism 5, where the wire stripping mechanism 5 strips the wire at both ends. Next, the wire is moved from the transfer module 1 to the terminal crimping mechanism 6. As needed, the vibrating plate 81 of the terminal feeding mechanism 8 transmits suitable terminals to the terminal crimping mechanism 6, which then crimps suitable terminals onto both ends of the wire sequentially. Next, the wire is moved from the transfer module 1 to the winding mechanism 7. The transfer gripper 70 grabs the wire from the transfer module 1 and moves it between the fixed adhesive plate 74 and the movable adhesive plate 75. The fourth lifting cylinder 76 lifts the movable adhesive plate 75 and attaches it to the fixed adhesive plate 74, attaching the upper and lower adhesive tapes to both sides of the wire. Then, the winding drive device 79 pulls the upper adhesive tape roll 72 and the lower adhesive tape roll 73 continuously, forming a U-shaped adhesive tape on the upper and lower adhesive tapes. Finally, the tape is wound into a roll for subsequent production.

[0038] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model.
