Description

Technical Field

[0001] This utility model relates to the field of wire harness braiding technology, and in particular to an insulating tape bonding, braiding, and cutting device for wires. Background Technology

[0002] In the electronics manufacturing industry, there is a need to produce wire harness braided tape. Wire harness braided tape consists of multiple wires of the same color pasted side by side into a "tape" shape, and the surface is covered with matte insulating paper (masking tape).

[0003] When mass-producing parallel wire harnesses, masking tape (high-temperature resistant insulating tape) needs to be precisely applied to the surface of multiple parallel wires. The bonded wires are then arranged into a flat strip structure at fixed intervals. The continuous braid is then cut into standard length segments (such as 300mm / 500mm), with the cuts kept flat and burr-free (to prevent damage to the wire insulation layer).

[0004] In existing technologies, the manufacturing of parallel-arranged wire harnesses requires manual threading, bonding, and cutting, resulting in low production efficiency. Differences in the pressing force of different operators lead to delamination rates and quality problems. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] This utility model provides a device for bonding, braiding, and cutting insulating tape to wires, which greatly improves production efficiency and reduces labor costs compared to traditional manual operations.

[0024] The following is combined with Figures 1-5 The technical solution provided by this utility model will be described in more detail.

[0025] See Figures 1-5 As shown, the insulating tape bonding, braiding, and cutting device provided by this utility model includes a frame 1, a cutting mechanism, an elastic mechanism, and two pressure rollers 3. The frame 1 has a sliding mounting part 11, and the pressure rollers 3 are rotatably connected to the corresponding mounting parts 11. Insulating tape (which can be masking tape in this embodiment) is wound around each pressure roller 3. One end of the elastic mechanism is fixed to the frame 1, and the other end abuts against the corresponding mounting part 11, thereby causing the two pressure rollers 3 to abut against each other and allowing the wire 20 to pass between the two pressure rollers 3. The wire 20, moving downwards sequentially, can pass between the two pieces of insulating tape wound around the pressure rollers 3 and bond with the insulating tape to form a braid. The cutting mechanism is located below one of the pressure rollers 3 and is used to cut the insulating tape between adjacent wires 20, thereby forming a braided wire harness of the target length.

[0026] The frame 1, as the supporting structure of the whole machine, is usually made of metal profiles (such as aluminum profiles or steel profiles) welded or bolted together to ensure sufficient rigidity and stability, and to provide a benchmark for the accurate installation and stable operation of other working parts.

[0027] The pressure roller 3 is a cylindrical roller, the outer surface of which can be made of a hard material or covered with an elastic material such as rubber or polyurethane to increase friction and buffer pressure, thereby better conforming to the contour of the wire 20. The pressure roller 3 is rotatably mounted on the mounting part 11 via bearings.

[0028] To achieve relative movement between the two pressure rollers 3, i.e., moving closer or further apart, the frame 1 is provided with a horizontal guide rail, and the mounting part 11 is correspondingly provided with a sliding groove that mates with the guide rail. This sliding connection allows at least one pressure roller 3 to move freely in the horizontal direction. In this embodiment, one pressure roller 3 can be fixed and the other movable, or both pressure rollers 3 can be movable. This not only allows the two pressure rollers 3 to be pressed together by applying pressure, but also facilitates their separation when changing materials or performing equipment maintenance.

[0029] As an optional implementation, see Figure 3 As shown, the elastic mechanism includes a shaft 61 and a second compression spring 62, wherein: the shaft 61 is horizontally arranged and fixed on the frame 1, the second compression spring 62 is sleeved on the shaft 61, one end of the second compression spring 62 is fixed to the frame 1, and the other end abuts against the corresponding mounting part 11, and the second compression spring 62 is in a compressed state.

[0030] Because the second compression spring 62 is pre-compressed, it generates a continuous elastic force, pushing the mounting part 11 and the pressure roller 3 mounted on it towards the other pressure roller 3 opposite, thereby causing the two pressure rollers 3 to come into close contact. This pressure generated by the spring is the preset pressure, the magnitude of which can be set by replacing springs with different stiffness coefficients or adjusting the pre-compression of the springs to adapt to the bonding process requirements of different wire diameters 20 and masking paper characteristics.

[0031] See Figure 1 As shown, the insulating tape bonding, braiding, and cutting device also includes grippers 8, which are used to hold or release the wire 20. The grippers 8 are located on one side or opposite sides of the frame 1, and are vertically movable.

[0032] See Figure 1The gripper 8 is designed to reliably grip and release multiple parallel wires 20. Gripper 8 is a mature technology in the industrial field and will not be described in detail here. It should be noted that gripper 8 is driven by a servo motor in conjunction with a ball screw or a vertical cylinder 9, thereby realizing the lifting action of gripper 8, thus achieving step-by-step, fixed-length feeding of wires 20, accurately conveying the part of wire 20 to be processed between the two pressure rollers 3.

[0033] As an optional implementation, see Figure 2 The frame 1 is also equipped with a guide conveying groove 4, which is vertically arranged and located below the gap between the two pressure rollers 3, and is used to guide the insulating tape to move downward.

[0034] As an optional implementation, see Figures 1-4 As shown, the insulating tape bonding wire, braiding and cutting device also includes a winding wheel mechanism 5. The winding wheel mechanism 5 is rotatably connected to the frame 1. There are two winding wheel mechanisms 5, which are located on the side of the corresponding pressure roller 3, and are used to carry the insulating tape roll 10.

[0035] For details, see Figures 1-4 As shown, the roll mechanism 5 includes a support shaft 51, a pressure plate 52, a rotating block 53, a positioning plate 54, and a first compression spring 55. The support shaft 51 is fixed to the frame 1. The pressure plate 52 and the positioning plate 54 are respectively fixed to the two ends of the support shaft 51. The rotating block 53 is rotatably mounted on the support shaft 51. The insulating tape roll 10 can be sleeved and fixed on the rotating block 53 and attached to the pressure plate 52. The first compression spring 55 is sleeved on the support shaft 51, with one end fixed to the pressure plate 52 and the other end abutting against the rotating block 53.

[0036] The first compression spring 55 is clamped between the first compression spring 55 and the baffle. The insulating tape roll 10 is sleeved on the rotating block 53. When the gripper 8 drives the wire 20 to descend, it drives the masking tape to descend. The rotating block 53 can rotate under the pull of the insulating tape, so that the insulating tape (masking tape) can be continuously released.

[0037] As an optional implementation, see Figure 1 , Figure 2 and Figure 5 As shown, the cutting mechanism includes a cutting blade 21, a driving device 22, and a fixing block 23, wherein: the driving device 22 is fixed on the frame 1, the fixing block 23 is fixed on the telescopic end of the driving device 22, the cutting blade 21 is mounted on the fixing block 23, the cutting blade 21 passes through the frame 1, and is used to cut the insulating tape between adjacent wires 20 when the driving device 22 telescopically extends.

[0038] The drive unit 22 can be a cylinder, hydraulic cylinder, or electromagnetic push rod, and its body is fixed to the frame 1. The telescopic end of the drive unit 22 is connected to the fixing block 23, and the cutting blade 21 is firmly mounted on the fixing block 23.

[0039] See Figure 1 , Figure 2 and Figure 5 As shown, to guide the movement of the cutting blade 21 and provide support, a horizontal blade groove 7 is formed on the frame 1 below the path through which the tape passes. The cutting blade 21 passes through the blade groove 7. When the control system issues a cutting command, the drive device 22 actuates (e.g., the cylinder piston rod extends), pushing the fixing block 23 and the cutting blade 21 to perform a rapid reciprocating linear motion along the direction of the blade groove 7. The sharp blade cuts across the tape laterally to complete the cutting action. Subsequently, the drive device 22 moves in the opposite direction to reset the cutting blade 21.

[0040] The complete working process of the device in this embodiment is described below: Before production begins, preparatory work is carried out, including mounting two rolls of insulating tape onto two winding roller mechanisms 5, and guiding the ends of the tapes to the corresponding pressure rollers 3, so that the adhesive surfaces of the two layers of tape are facing each other. Simultaneously, a bundle (or multiple strands) of wire 20 to be braided is aligned parallel and clamped by grippers 8. The wire 20 and tape are guided to the pressing position. Specifically, the control system drives the grippers 8 to move downwards by a preset step distance, feeding the starting end of the wire 20 into the pressing gap between the two abutting pressure rollers 3. At the same time, the upper and lower layers of insulating tape are also fed into this gap as the pressure rollers 3 rotate, clamping the wire 20 in the middle. Pressure is applied and pressed to form a continuous braid. Under the continuous pressure provided by the second compression spring 62, the two pressure rollers 3 tightly press the three layers of material—the two layers of insulating tape and the wire 20—together, so that the wire 20 is firmly bonded between the two layers of tape. The pressure roller 3 can rotate passively (driven by the feeding action of the gripper 8) or actively (driven by an independent micro motor). Its rotation causes the pressed portion to move downwards, forming a continuous flat strip of braided tape. The braided tape is conveyed to a predetermined length. The gripper 8 holds the wire 20, and under the drive of the vertical cylinder 9, the braided tape is continuously generated and conveyed downwards. When the braided tape length reaches the preset value, the drive device 22 of the cutting mechanism drives the cutting blade 21 to quickly slice across the braided tape laterally, cutting it off. Finally, the finished wire harness braided tape is output. The cut section of the finished wire harness braided tape, which meets the preset length, falls into the collection box below due to gravity. Subsequently, the cutting blade 21 resets, and the gripper 8 continues to convey the wire 20, starting the next production cycle.
