Description

Technical Field

[0001] This invention relates to a wire binding machine. Background Technology

[0002] Wire binding machines are used to bundle assembled products that require further securing. They can be applied to binding automotive radiators, facilitating their transfer and transport. The working principle is to feed and maneuver wire to frame the product to be bundled, then use mechanical grippers to tighten both ends of the wire, thus securing it tightly. Currently, after bundling, existing wire binding machines typically directly convey the bundled product out or have a robotic arm remove it. However, the ends of the bundled wire are usually pointing outwards and not flattened. In this state, subsequent movement of the product can easily cause scratches to operators, damage to the equipment, or scratches between products. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this invention proposes a wire-binding device that can flatten the wire-binding head.

[0004] A wire binding machine includes a frame and a wire feeding assembly, a wire detour assembly, a wire tightening and flattening assembly, and a wire binding platform mounted on the frame. During operation, the wire is drawn out from the wire feeding assembly, forms a U-shape after passing through the wire detour assembly, and covers the part to be bound on the wire binding platform. Then, the two ends of the wire are tightened by the wire tightening and flattening assembly, and the head is flattened.

[0005] The wire binding and detour assembly includes a U-shaped wire feeding component, with one end being the wire inlet and the other end being the wire outlet, and the two ends are arranged vertically.

[0006] The wire feeding assembly is installed near the wire feeding end of the wire detour assembly and is able to feed the wire to the wire detour assembly.

[0007] The wire-binding platform is located within the coverage area of ​​the U-shaped wire feeding component, thereby allowing the component to be bound at the top of the device to be within the bounding range after the winding and bending.

[0008] The wire binding tightening and flattening assembly is located between the discharge end of the wire binding discharge assembly and the wire binding detour assembly, and includes a tightening moving seat, a tightening mechanical claw, and a flattening push drive. Specifically, the tightening moving seat is slidably mounted on the frame via a track facing the wire binding detour assembly. The tightening mechanical claw is fixedly mounted on the tightening moving seat and faces the wire binding detour assembly, and the tightening mechanical claw has a pressing surface facing the wire binding detour assembly. The flattening push drive is mounted on the frame and drives the tightening moving seat to move closer to / away from the wire binding detour assembly. Upon startup, the tightening moving seat drives the tightening mechanical claw closer to the wire binding detour assembly, fixing and twisting both ends of the U-shaped binding wire to tighten it. Finally, the tightening mechanical claw releases the binding head, and under the drive of the tightening moving seat, the pressing surface presses down on the binding head, flattening it to prevent the binding head from scratching operators, equipment, or other bound components.

[0009] This invention, by setting up a binding wire tightening and flattening component with a pressing plane, can effectively flatten the binding head of the binding wire, solving the problem of the binding head scratching operators, equipment, or other already bound parts, and improving the safety of binding work.

[0010] Preferably, the wire feeding assembly includes a wire feeding spool placement component and a wire feeding buffer component. The wire feeding buffer component is disposed between the wire feeding spool placement component and the wire tightening and flattening component, and includes a wire feeding fixing seat, a wire feeding lifting seat, a lifting guide rail, a fixing roller, and a lifting roller. The wire feeding fixing seat is mounted on the frame, and at least one fixing roller is arranged in a row and rotatably mounted on the wire feeding fixing seat. The wire feeding lifting seat is movably mounted on the frame via the lifting guide rail and is located at the bottom of the wire feeding fixing seat. At least one lifting roller is arranged in a row and rotatably mounted on the wire feeding lifting seat. The wire feeding spool on the wire feeding spool placement component draws out the wire, which passes sequentially around the fixing roller and the lifting roller. When the wire drawn from the wire feeding spool is too long, the lifting roller moves downward under gravity, unfolding the wire and preventing it from becoming loose, falling off, or tangling. When the wire is pulled out externally or the wire feeding spool is reversed for retraction, the lifting roller rises to prevent the wire from being suddenly subjected to a large pulling force and breaking.

[0011] Preferably, there are five fixed rollers and four lifting rollers. The bottom of the lifting guide rail is provided with a buffer pad facing the bottom of the wire feeding lifting seat to prevent excessive vibration when the lifting seat descends to the bottom. The wire feeding assembly also includes two axially vertical guide wheels and two sets of axially horizontal guide wheels installed close together vertically to guide the pulled-out wire. The vertically close-installed guide wheels are driven to rotate by a motor, which can press down and pull out the wire.

[0012] Preferably, the wire bundling spool placement component includes a wire feeder and a fixing rod. The wire feeder is mounted on the frame and is connected to drive the fixing rod to rotate forward and backward, thereby enabling wire feeding and winding.

[0013] Preferably, the tightening mechanical claw includes a binding clamp, a rotating base, and a tightening rotating motor. The binding clamp is mounted on the tightening movable base via the rotating base and is driven to rotate by the tightening rotating motor, thereby tightening the binding wire. Specifically, the binding clamp includes a telescopic rod, an upper clamp, a lower clamp, a side plate, a pressing seat, and a telescopic drive component. Both the rotating base and the tightening movable base are provided with telescopic limiting through holes. The telescopic rod is installed through the telescopic limiting through holes and is driven to rotate by the rotating base. The telescopic rod and the telescopic limiting through holes are axially movable relative to each other, and the telescopic rod is provided with a through hole. The upper and lower clamps are symmetrically mounted vertically and hinged to the side of the telescopic rod facing the binding wire meandering assembly. The pressing seat is mounted on the rotating base via the side plate, and the pressing seat is located between the clamping surfaces of the upper and lower clamps. The surface of the pressing seat facing the binding wire meandering assembly is the pressing plane. The telescopic drive is mounted on the tightening movable seat and drives the telescopic rod to reciprocate. The rotating seat pushes the upper and lower jaws through the opening of the telescopic limiting through hole, closing the upper and lower jaws and clamping the pressing seat. An elastic element is provided between the upper and lower jaws, or between the upper jaw and the side plate / pressing seat, and between the lower jaw and the side plate / pressing seat, to provide tension for opening the upper and lower jaws. In use, the telescopic drive moves the telescopic rod backward relative to the telescopic limiting through hole. When the outer side of the hinge of the upper and lower jaws reaches the telescopic limiting through hole, and the telescopic rod further retracts, the upper and lower jaws close relative to each other, achieving the action of gripping and clamping the binding wire head. Then, the tightening rotary motor drives the entire binding wire clamp to rotate, tightening the binding wire.

[0014] Preferably, both the upper and lower grippers are provided with triangular shearing protrusions facing the pressing seat, which can press the binding wire tighter and also cut the binding wire. A guide strip is provided above the middle of the lower gripper, and a guide hole is provided in the guide strip. One end of the guide hole is connected to or separate from the through hole of the telescopic rod, and the other end points between the lower gripper and the pressing seat and toward the wire feeding end of the binding wire detour assembly. In use, the binding wire is pulled out from the binding wire discharge assembly, and the wire end passes through the through hole of the telescopic rod, the guide hole of the guide strip, between the lower gripper and the pressing seat, the wire feeding end of the binding wire detour assembly, and the wire discharging end in sequence.

[0015] Preferably, the U-shaped wire feeding component includes a vertical support base, a first U-shaped plate, a second U-shaped plate, and an opening / closing drive component. The vertical support base is mounted on the frame and is spaced apart from the wire binding and tightening assembly. The middle portion of the first U-shaped plate is mounted on the vertical support base, with its opening facing the wire binding and tightening assembly. The second U-shaped plate is mounted on the first U-shaped plate through guide holes and guide rods. The opening / closing drive component is mounted on the vertical support base, the first U-shaped plate, or the second U-shaped plate, and drives the second U-shaped plate closer to / away from the first U-shaped plate, thereby enabling the wire binding to be pulled out between the first and second U-shaped plates. U-shaped wire feeding grooves are provided on the opposing surfaces of the first and second U-shaped plates.

[0016] Preferably, the opening and closing drive component comprises two sets, including a telescopic bar, a top-opening roller, and an opening and closing cylinder. Horizontal strip grooves are formed on the upper and lower sides of the opposing surfaces of the first and second U-shaped plates, and several clearance grooves are provided along these strip grooves. The edges connecting the clearance grooves to the strip grooves are chamfered / rounded to form a slope. The number of top-opening rollers is consistent with the number of clearance grooves, and they are rotatably mounted along the telescopic bar with a vertical rotating shaft. The diameter of the top-opening rollers is larger than the diameter of the telescopic bar. The opening and closing cylinder is mounted on a vertical support base and drives the telescopic bar to extend / retract. The telescopic bar drives the top-opening rollers to roll out / retract into the clearance grooves, thereby separating the first and second U-shaped plates. A spring is provided between the first and second U-shaped plates to provide a merging force, providing a restoring force for the first and second U-shaped plates to re-adhere.

[0017] Preferably, the binding wire detour assembly further includes a horizontal moving base, a horizontal moving drive, a fixed clamping block, a clamping drive, a movable clamping block, a pneumatic gripper, and a lifting cylinder. The vertical support base is slidably mounted on the frame via the horizontal moving base. The horizontal moving drive connects and drives the horizontal moving base to move along the binding wire platform, thereby enabling binding wire to be tied at different positions on the object. The fixed clamping block is installed on the side near the wire inlet end of the U-shaped wire feeding component. The clamping drive is mounted on the horizontal moving base and connects and drives the movable clamping block to move closer to / away from the fixed clamping block, clamping / releasing the bound object together with the fixed clamping block. The pneumatic gripper is mounted on the frame via the lifting cylinder and reciprocates between the wire outlet end of the U-shaped wire feeding component and the tightening mechanical gripper, enabling the binding wire head extending from the wire outlet end of the U-shaped wire feeding component to be clamped and transferred to the tightening mechanical gripper, thus tightening both ends of the binding wire.

[0018] Preferably, there are at least two sets of the wire feeding assembly, the wire detour assembly, and the wire tightening and flattening assembly, which can simultaneously bind multiple wires on the binding component, thereby improving work efficiency.

[0019] As can be seen from the above description of the present invention, the present invention has the following beneficial effects:

[0020] 1. By setting up a binding wire tightening and flattening component with a pressure surface, the binding head of the binding wire can be effectively flattened, solving the problem of the binding head scratching operators, equipment or other already bound parts, and improving the safety of binding work;

[0021] 2. By setting up a wire-out buffer component, not only can excess wire be unfolded to prevent the wire from loosening, falling off, or tangling, but the wire can also be prevented from being torn due to excessive force during the pulling process.

[0022] 3. The U-shaped wire feeding component adopts an opening and closing drive component with telescopic strips and top opening rollers, which can evenly separate the first U-shaped plate and the second U-shaped plate, and has a simple structure and occupies little space;

[0023] 4. By setting up a U-shaped wire feeding component, not only can the binding work be carried out effectively and efficiently, but the wire can also be threaded in the U-shaped wire feeding component in advance during the conveying of the bound products, thereby improving the overall binding efficiency.

[0024] 5. By setting up an active clamping block, this application can clamp the parts to be bundled during the bundling operation, ensuring smooth bundling and improving the bundling quality. Attached Figure Description

[0036] To make the technical problems, solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention.

[0037] Please see Figures 1 to 8 A wire binding machine includes a frame 1 and a wire feeding assembly 2, a wire detour assembly 3, a wire tightening and flattening assembly 4, and a wire binding platform 5 mounted on the frame 1. During operation, the wire is drawn out from the wire feeding assembly 2, forms a U-shape after passing through the wire detour assembly 3, and covers the wire-to-be-bound component on the wire binding platform 5. Then, the two ends of the wire are tightened by the wire tightening and flattening assembly 4, and the head is flattened.

[0038] In this embodiment, the wire bundling and discharge assembly 2 includes a wire bundling tube placement component and a wire bundling and discharge buffer component.

[0039] The wire-bundling and feeding buffer component is disposed between the wire-bundling tube placement component and the wire-bundling tightening and flattening assembly 4, and includes a wire-feeding fixing seat 21, a wire-feeding lifting seat 22, a lifting guide rail 23, fixed rollers 24, and lifting rollers 25. The wire-feeding fixing seat 21 is mounted on the frame 1, and at least one fixed roller 24 is arranged in a row and rotatably mounted on the wire-feeding fixing seat 21. The wire-feeding lifting seat 22 is movably mounted on the frame 1 via the lifting guide rail 23 and is located at the bottom of the wire-feeding fixing seat 21. At least one lifting roller 25 is arranged in a row and rotatably mounted on the wire-feeding lifting seat 22. The binding wire is drawn out from the binding spool on the binding spool placement component and passes sequentially around the fixed roller 24 and the lifting roller 25. When the binding wire drawn out from the binding spool is too long, the lifting roller 25 moves down under the action of gravity and unfolds the binding wire to prevent the binding wire from becoming loose, falling off, or tangling. When the binding wire is pulled out from the outside or the binding spool is reversed and retracted, the lifting roller 25 rises to prevent the binding wire from being suddenly subjected to a large pulling force and being torn off.

[0040] In one embodiment, there are five fixed rollers 24 and four lifting rollers 25. The bottom of the lifting guide rail 23 is provided with a buffer pad 26 facing the bottom of the wire output lifting seat 22, which can prevent large vibrations when the bottom of the lifting seat descends to the bottom. The wire binding and discharging assembly 2 also includes two axially vertical guide wheels 27 and two sets of axially horizontal guide wheels 27 installed close together vertically, which guide the pulled-out wire. In this embodiment, the paired and vertically arranged guide wheels 27 are driven to rotate by a motor, which can pull out and output the wire.

[0041] The wire bundling spool placement component includes a wire feeder / discharger 28 and a fixing rod 29. The wire feeder / discharger 28 is mounted on the frame 1 and is connected to drive the fixing rod 29 to rotate forward / reverse, thereby enabling wire feeding and wire take-up.

[0042] The wire binding and detour assembly 3 includes a U-shaped wire feeding component, with one end being the wire inlet and the other end being the wire outlet, and the two ends being arranged vertically.

[0043] In one embodiment, the U-shaped wire feeding component includes a vertical support base 31, a first U-shaped plate 32, a second U-shaped plate 33, and an opening / closing drive 34. The vertical support base 31 is mounted on the frame 1 and is spaced apart from the wire binding and tightening assembly 4. The first U-shaped plate 32 is mounted on the vertical support base 31 at its center, with its opening facing the wire binding and tightening assembly 4. The second U-shaped plate 33 is mounted on the first U-shaped plate 32 through a guide hole and a guide rod. The opening / closing drive 34 is mounted on the vertical support base 31, the first U-shaped plate 32, or the second U-shaped plate 33, and drives the second U-shaped plate 33 to move closer to / away from the first U-shaped plate 32, thereby enabling the wire binding to be pulled out between the first U-shaped plate 32 and the second U-shaped plate 33. U-shaped wire feeding grooves 331 are provided on the opposing surfaces of the first U-shaped plate 32 and the second U-shaped plate 33.

[0044] The opening and closing drive component 34 has two sets, including a telescopic bar 341, a top-opening roller 342, and an opening and closing cylinder 343. Horizontal strip grooves 332 are formed on the upper and lower sides of the opposing surfaces of the first U-shaped plate 32 and the second U-shaped plate 33, and several clearance grooves are provided along the strip grooves 332. The edges of the clearance grooves connecting to the strip grooves 332 are chamfered / rounded to form a slope. The number of top-opening rollers 342 is the same as the number of clearance grooves, and they are rotatably installed along the telescopic bar 341 with a vertical axis of rotation. The diameter of the top-opening rollers 342 is larger than the diameter of the telescopic bar 341. The opening and closing cylinder 343 is mounted on a vertical support base 31 and drives the telescopic bar 341 to extend / retract. The telescopic bar 341 drives the top-opening rollers 342 to roll out / retract into the clearance grooves, thereby separating the first U-shaped plate 32 and the second U-shaped plate 33. A spring is provided between the first U-shaped plate 32 and the second U-shaped plate 33 to provide a merging force, thereby providing a restoring force for the first U-shaped plate 32 and the second U-shaped plate 33 to re-adhere.

[0045] In other embodiments, the binding wire detour assembly 3 further includes a horizontal moving base 35, a horizontal moving drive, a fixed clamping block 36, a clamping drive, a movable clamping block 37, a pneumatic gripper 38, and a lifting cylinder 39. The vertical support base 31 is slidably mounted on the frame 1 via the horizontal moving base 35. The horizontal moving drive connects and drives the horizontal moving base 35 to move along the binding wire platform 5, thereby enabling binding wire to be tied at different positions on the object. The fixed clamping block 36 is installed on the side near the wire inlet end of the U-shaped wire feeding component. The clamping drive is mounted on the horizontal moving base 35 and connects and drives the movable clamping block 37 to move closer to / away from the fixed clamping block 36, clamping / releasing the bound object together with the fixed clamping block 36. The pneumatic gripper 38 is mounted on the frame 1 via a lifting cylinder 39 and moves back and forth between the wire output end of the U-shaped wire feeding component and the tightening mechanical gripper 42. It can grip the binding head extending from the wire output end of the U-shaped wire feeding component and transfer it to the tightening mechanical gripper 42, so that the two ends of the binding wire can be tightened.

[0046] The wire feeding assembly 2 is installed near the wire feeding end of the wire detour assembly 3 and can feed the wire to the wire detour assembly 3.

[0047] The wire-binding platform 5 is located within the coverage area of ​​the U-shaped wire feeding component, thereby allowing the component to be bound at the top of the device to be within the bounding range after the winding and bending.

[0048] The wire binding tightening and flattening assembly 4 is disposed between the discharge end of the wire binding discharge assembly 2 and the wire binding detour assembly 3, and includes a tightening moving seat 41, a tightening mechanical claw 42, and a flattening pushing drive 43. Specifically, the tightening moving seat 41 is slidably mounted on the frame 1 via a track facing the wire binding detour assembly 3. The tightening mechanical claw 42 is fixedly mounted on the tightening moving seat 41 and faces the wire binding detour assembly 3, and the tightening mechanical claw 42 has a pressing surface 421 facing the wire binding detour assembly 3. The flattening pushing drive 43 is mounted on the frame 1 and is connected to drive the tightening moving seat 41 to move closer to / away from the wire binding detour assembly 3. Upon startup, the tightening moving seat 41 drives the tightening mechanical claw 42 to approach the binding wire detour assembly 3, fixing and twisting both ends of the U-shaped binding wire to tighten it. Finally, the tightening mechanical claw 42 loosens the binding head of the binding wire, and under the action of the tightening moving seat 41, the pressing plane 421 presses against the binding head to flatten it, preventing the binding head from scratching the operator, equipment, or other already bound parts.

[0049] In one embodiment, the tightening mechanical claw 42 includes a binding clamp 422, a rotating base 423, and a tightening rotating motor 424. The binding clamp 422 is mounted on the tightening movable base 41 via the rotating base 423 and is driven to rotate by the tightening rotating motor 424, thereby tightening the binding wire. Specifically, the binding clamp 422 includes a telescopic rod 4221, an upper clamp 4222, a lower clamp 4223, a side plate 4224, a pressing base 4225, and a telescopic drive member 4226. Both the rotating base 423 and the tightening movable base 41 are provided with telescopic limiting through holes 411. The telescopic rod 4221 is installed through the telescopic limiting through hole 411 and is driven to rotate by the rotating base 423. The telescopic rod 4221 and the telescopic limiting through hole 411 are axially movable relative to each other, and the telescopic rod 4221 is provided with a through hole. The upper clamping jaw 4222 and lower clamping jaw 4223 are symmetrically mounted and hinged to the side of the telescopic rod 4221 facing the wire binding detour assembly 3. The pressing seat 4225 is mounted on the rotating seat 423 via the side plate 4224, and the pressing seat 4225 is located between the clamping surfaces of the upper clamping jaw 4222 and lower clamping jaw 4223. The surface of the pressing seat 4225 facing the wire binding detour assembly 3 is the pressing plane 421. The telescopic drive member 4226 is mounted on the tightening moving seat 41 and drives the telescopic rod 4221 to reciprocate. The rotating seat 423 pushes the upper clamping jaw 4222 and lower clamping jaw 4223 through the opening of the telescopic limiting through hole 411, and the upper clamping jaw 4222 and lower clamping jaw 4223 close and clamp the pressing seat 4225. Between the upper gripper 4222 and the lower gripper 4223, or between the upper gripper 4222 and the side plate 4224 / pressing seat 4225, and between the lower gripper 4223 and the side plate 4224 / pressing seat 4225, there is an elastic element that provides tension for the opening between the upper gripper 4222 and the lower gripper 4223. In use, the telescopic drive member 4226 drives the telescopic rod 4221 to move backward relative to the telescopic limiting through hole 411. When the outer side of the hinge of the upper gripper 4222 and the lower gripper 4223 abuts against the telescopic limiting through hole 411, and the telescopic rod 4221 further retracts, the upper gripper 4222 and the lower gripper 4223 will close relative to each other, realizing the action of gripping and clamping the head of the binding wire. Then, the tightening rotation motor 424 drives the entire binding wire clamp 422 to rotate, thereby tightening the binding wire.

[0050] Preferably, both the upper gripper 4222 and the lower gripper 4223 are provided with triangular shearing protrusions facing the pressing seat 4225, which can press the binding wire tighter and also cut the binding wire. A guide strip is provided above the middle of the lower gripper 4223, and a guide hole is provided in the guide strip. One end of the guide hole is connected to or separate from the through hole of the telescopic rod 4221, and the other end points between the lower gripper 4223 and the pressing seat 4225 and toward the wire feeding end of the binding wire detour assembly 3. In use, the binding wire is pulled out from the binding wire discharge assembly 2, and the wire end passes through the through hole of the telescopic rod 4221, the guide hole of the guide strip, between the lower gripper 4223 and the pressing seat 4225, the wire feeding end of the binding wire detour assembly 3, and the wire discharging end in sequence.

[0051] The present invention, by setting a binding wire tightening and flattening component 4 with a pressing plane 421, can effectively flatten the binding head of the binding wire, solve the problem of the binding head scratching the operator, equipment or other already bound parts, and improve the safety of binding work.

[0052] In other embodiments, there are two sets of the wire feeding assembly 2, the wire detour assembly 3, and the wire tightening and flattening assembly 4, which can bind two bundles of wire at the same time, thereby improving the binding speed.

[0053] The wire binding machine provided by this invention can be used to bind heat sinks. Before use, the wire binding spool is placed on the wire binding spool placement component of the wire binding discharge assembly 2. The wire is pulled out and passes sequentially around the fixed roller 24 and lifting roller 25 of the wire binding discharge buffer component. The wire is then output along the guide wheel 27 and arrives at the position of the wire binding tightening and flattening assembly 4. The wire is then sequentially passed through the through hole of the telescopic rod 4221, the guide hole of the guide strip, between the lower clamp 4223 and the pressing seat 4225, and the wire feeding end of the wire binding detour assembly 3. When starting the wire binding equipment, the heat sink is placed on the wire binding platform 5. The wire binding platform 5 moves back and forth on the frame 1 in a direction perpendicular to the U-shaped wire feeding component via an adjustment drive component, so that the wire can be bound at different positions on the object. The paired guide wheels 27 are driven to rotate by a motor, thereby pulling out and continuously outputting the binding wire. After the binding wire head enters the wire feeding end of the binding wire detour assembly 3, it moves along the binding wire detour assembly 3, is folded into a U-shape, and encircles the heat sink. The binding wire head extends out from the wire output end of the binding wire detour assembly 3, is gripped by the pneumatic gripper 38, and transferred to the tightening mechanical gripper 42. At this time, the tightening mechanical gripper 42 simultaneously grips both ends of the U-shaped binding wire, and when rotated, it tightens and binds it to the heat sink, completing the binding action. Afterwards, the pressure plane 421 flattens the head of the binding wire.

[0054] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
