Technical Field

[0001] This utility model relates to the field of automated bundling equipment technology, and in particular to a cable tie bundling device. Background Technology

[0002] In industries such as electronics assembly, electrical manufacturing, and automotive wiring harnesses, it is often necessary to bundle multiple wires or cable ties into neat bundles for easy wiring, securing, and protection. Traditional bundling methods rely heavily on manual operation, using cable ties or O-rings for manual bundling, which suffers from low efficiency, poor consistency, and high labor intensity. Especially when there are many cable ties, it is difficult for manual labor to quickly organize and bundle them, easily resulting in loose ties, loose bundling, or misalignment, affecting product quality and production efficiency. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a cable tie bundling device with a simple structure and a high degree of automation.

[0004] The main contents of this utility model include: a cable tie feeding mechanism for gripping multiple cable ties and conveying them in the form of a cable tie bundle; an O-ring feeding mechanism for gripping and conveying O-rings; and a bundling execution mechanism, which includes a support frame, an O-ring expansion component, an O-ring pushing component, and a cable tie pre-threading unit disposed on one side of the support frame, for receiving the cable tie bundle from the cable tie feeding mechanism and the O-rings from the O-ring feeding mechanism, and expanding the O-rings and bundling them onto the cable tie bundle.

[0005] Preferably, the O-ring expansion assembly includes multiple sets of expansion units, each set of expansion units including a telescopic cylinder and a pull rod connected to the output end of the telescopic cylinder. The axis of the pull rod is arranged along a first horizontal direction, and the pull rods of the multiple sets of expansion units can be assembled into a cylindrical structure when the telescopic cylinder is in the extended state for the O-ring to be fitted.

[0006] Preferably, the O-ring pushing assembly includes a push plate and a lateral drive component that drives the push plate to move along a first horizontal direction. The push plate is provided with a through hole, which is coaxially arranged with the pull rod in the spliced ​​state, and the size of the through hole is larger than the diameter of the cable tie bundle so that the cable tie bundle can pass through.

[0007] Preferably, positioning holes are provided at the four corners of the through hole of the push plate to limit the displacement stop position of the pull rod when the telescopic cylinder retracts.

[0008] Preferably, the cable tie pre-threading unit includes a clamping cylinder and two sets of guide plates connected to the output end of the clamping cylinder. Each set of guide plates has a semi-circular hole on an adjacent side. The guide plates are driven by the clamping cylinder to swing so that when in the closed state, the two semi-circular holes are joined together to form a guide hole. The diameter of the guide hole is larger than the diameter of the cable tie bundle so that the cable tie bundle can pass through.

[0009] Preferably, the side of the guide plate opposite to the push plate is configured as a tapered surface that gradually expands circumferentially with the guide hole as the center, for guiding the end of the cable tie bundle.

[0010] Preferably, the cable tie feeding mechanism includes a cable tie gripping component, a first lifting drive component that drives the cable tie gripping component to move in a vertical direction, and a first lateral drive component that drives the cable tie gripping component to move laterally in a first horizontal direction.

[0011] Preferably, the cable tie gripping assembly includes a bidirectional drive cylinder, with its two output ends arranged along a second horizontal direction, which is perpendicular to the first horizontal direction. The output ends of the bidirectional drive cylinder are respectively connected to a first clamping arm and a second clamping arm to grip multiple cable ties radially.

[0012] Preferably, the inner sides of the first clamping arm and the second clamping arm are provided with a gathering structure. The gathering structure includes a first gathering plate and a second gathering plate. The first gathering plate is provided with a first V-groove and a mating groove extending along a first horizontal direction. The second gathering plate is provided with a second V-groove and a mating protrusion that cooperates with the mating groove. When the bidirectional cylinder drives the first clamping arm and the second clamping arm to close, the mating protrusion is inserted into the mating groove, and the first V-groove and the second V-groove cooperate to form a receiving groove for accommodating the cable tie bundle.

[0013] Preferably, the O-ring feeding mechanism includes an O-ring vibratory feeder, an O-ring gripping assembly, a second lifting drive assembly that drives the O-ring gripping assembly to move in a vertical direction, and a second transverse drive assembly that drives the O-ring gripping assembly to move in a first horizontal direction.

[0016] The technical solution protected by this utility model will be described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 As shown, this application proposes a cable tie bundling device, which includes a cable tie feeding mechanism 1, an O-ring feeding mechanism 2, and a bundling execution mechanism 3. The cable tie feeding mechanism 1 is responsible for grabbing multiple cable ties and conveying them to the bundling execution mechanism 3 in a bundle form; the O-ring feeding mechanism 2 is responsible for grabbing and conveying O-rings; the bundling execution mechanism 3 receives the cable tie bundle and the O-rings, and completes the bundling operation by expanding the O-rings and bundling them onto the cable tie bundle.

[0018] like Figure 2 As shown, the cable tie feeding mechanism 1 includes a cable tie gripping assembly 11, a first lifting drive assembly 12 that drives the cable tie gripping assembly 11 to move up and down in the vertical direction, and a first lateral drive assembly 13 that drives the cable tie gripping assembly 11 to move laterally in the first horizontal direction. like Figure 2-3 As shown, the cable tie gripping assembly 11 includes a bidirectional drive cylinder 111, with its two output ends arranged along a second horizontal direction (perpendicular to the first horizontal direction). The two output ends are respectively connected to a first clamping arm 112 and a second clamping arm 113. The bidirectional drive cylinder 111 drives the two clamping arms to close or open radially, thereby gripping multiple cable ties.

[0019] like Figure 2-3 As shown, the inner sides of the first clamping arm 112 and the second clamping arm 113 are provided with a convergence structure, including a first convergence plate 114 and a second convergence plate 115. The first convergence plate 114 has a first V-groove 1141 in the middle section of its side wall near the second convergence plate 115, and the second convergence plate 115 has a corresponding second V-groove 1151 in the middle section of its side wall near the first convergence plate 114. The first convergence plate 114 has a mating groove 1142 formed at its center along a second horizontal direction, and the second convergence plate 115 has a mating protrusion 1152 that mates with the mating groove 1142.

[0020] When the bidirectional drive cylinder 111 drives the first clamping arm 112 and the second clamping arm 113 to close, the mating protrusion 1152 inserts into the mating groove 1142. The first V-groove 1141 and the second V-groove 1151 cooperate to form a receiving area for receiving and gripping a bundle of cable ties. Through the two sets of V-grooves and the mating structure, the cable tie bundle is effectively gathered and positioned during the gripping process, preventing the cable ties from scattering and improving gripping stability and neatness.

[0021] like Figure 4As shown, the O-ring feeding mechanism 2 includes an O-ring vibratory feeder 21, an O-ring gripping assembly 22, a second lifting drive assembly 23, and a second lateral drive assembly 24. The O-ring vibratory feeder 21 is used for automatic feeding, vibrating the O-rings one by one to the discharge port. The O-ring gripping assembly 22 includes a gripping cylinder 221 and a lateral slide 222. The gripping cylinder 221 grips the O-rings, and the lateral slide 222 drives the gripping cylinder 221 to move laterally along a first horizontal direction, achieving precise feeding. The second lifting drive assembly 23 and the second lateral drive assembly 24 respectively drive the O-ring gripping assembly 22 to move vertically and laterally along the first horizontal direction. The gripping cylinder 221 grips the O-ring from the discharge end of the O-ring vibratory plate 21. The second lifting drive component 23 and the second lateral drive component 24 drive the movement to initially position the O-ring in place. Then, the lateral slide table 222 further delivers the O-ring precisely to ensure that the O-ring is accurately placed on the O-ring expansion component 32, thereby improving feeding efficiency and positional accuracy.

[0022] like Figure 5-7 As shown, the strapping actuator 3 includes a support frame 31, an O-ring expansion assembly 32, an O-ring pushing assembly 33, and a cable tie pre-threading unit 34 disposed on one side of the support frame 31.

[0023] like Figure 5-7 As shown, the O-ring expansion assembly 32 includes four sets of expansion units 321, evenly spaced on the side end face of the support frame 31. Each expansion unit 321 includes a telescopic cylinder 3211 and a pull rod 3212 connected to its output end, with the axis of the pull rod 3212 arranged along a first horizontal direction. When the telescopic cylinder 3211 is in the extended state, the four sets of pull rods 3212 can be assembled into a columnar structure for the O-ring to be fitted; when the telescopic cylinder 3211 retracts, the four sets of pull rods 3212 open outward, driving the O-ring to expand. The multiple sets of pull rods are assembled to form a columnar structure, ensuring that the O-ring can be stably fitted onto it, and then the telescopic cylinder synchronously drives it to retract, making the O-ring expansion process uniform and avoiding deformation or damage to the O-ring.

[0024] like Figure 5-7 As shown, the O-ring pushing assembly 33 includes a push plate 331 and a lateral drive component 332 (such as a telescopic cylinder) that drives the push plate 331 to move along a first horizontal direction. The push plate 331 has a through hole 333, which is coaxially arranged with the pull rod 3212 in its assembled state. The pull rod 3212 passes through the through hole 333 axially, with a portion protruding from one side of the push plate 331 along the first horizontal direction to receive the O-ring. The size of the through hole 333 is larger than the diameter of the cable tie bundle to allow the cable tie bundle to pass through.

[0025] Positioning holes 3331 are provided at the four corners of the perforation 333 to limit the displacement stop position of the pull rod 3212 when the telescopic cylinder 3211 retracts. The positioning holes 3331 ensure that the pull rod 3212 is accurately positioned when retracting, and that the trajectory of the push plate 331 pushing the O-ring is stable, avoiding O-ring offset or jamming.

[0026] Preferably, a guide mechanism is provided between the push plate 331 and the support frame 31, which includes a guide sleeve fixed on the support frame 31 and a guide rod movably passing through the guide sleeve. One end of the guide rod is fixed on the push plate. The stability of the push plate pushing process is improved by the limitation of the guide mechanism.

[0027] like Figure 5-7 As shown, the cable tie pre-threading unit 34 includes a clamping cylinder 341 and two sets of guide plates 342 disposed at the output end of the clamping cylinder 341. Semicircular holes are provided on adjacent sides of the guide plates 342. Driven by the clamping cylinder 341, the two semicircular holes merge into a guide hole 343 in the closed state. The guide hole 343 is coaxially arranged with the through hole 333 on the push plate 331. In the open state, the two sets of guide plates 342 can avoid the O-ring feeding and the movement of the push plate 331. The diameter of the guide hole 343 is larger than the diameter of the cable tie bundle, allowing the cable tie bundle to pass through.

[0028] Preferably, the side end face of the guide plate 342 opposite to the push plate 331 is configured as a tapered surface that gradually expands circumferentially with the guide hole 343 as the center. The tapered surface guides the end of the cable tie bundle, making it easier for the cable tie bundle to be smoothly inserted into the guide hole 343 and the O-ring, reducing the resistance of threading.

[0029] Working principle: The O-ring vibratory feeder 21 vibrates the O-ring to the discharge port. The O-ring gripping assembly 22 grips the O-ring and moves it to the front of the push plate 331, coaxial with the through hole 333, via the second lifting drive assembly 23 and the second lateral drive assembly 24. At this time, the guide plate 342 of the cable tie pre-threading unit 34 is in the open state, and the pull rod 3212 of the O-ring expansion assembly 32 is in the assembled state. The lateral slide 222 further drives the gripping cylinder 221 to move closer to the push plate 331, placing the O-ring onto the assembled pull rod 3212. Subsequently, the telescopic cylinder 3211 retracts, the pull rod 3212 opens and moves to the position of the positioning hole 3331, and the O-ring is expanded.

[0030] The cable tie gripping assembly 11 grips multiple cable ties to form a cable tie bundle. Its position is adjusted by the first lifting drive assembly 12 and the first lateral drive assembly 13, ensuring the cable tie bundle axis is coaxial with the guide hole 343. The clamping cylinder 341 drives the guide plate 342 to close, forming the guide hole 343. The cable tie bundle moves laterally along the first horizontal direction, its ends converging through a tapered surface before being inserted into the guide hole 343, and partially passing through the expanded O-ring.

[0031] The guide plate 342 opens to avoid interference, and the lateral drive 332 drives the push plate 331 to move along the first horizontal direction, pushing the O-ring off the pull rod 3212. When the O-ring detaches from the pull rod, it quickly contracts under the action of elasticity, tightening itself onto the cable tie bundle, thus completing the binding.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
