Description

Technical Field

[0001] This invention relates to a wiring harness binding device, specifically a wiring harness binding device for air conditioning harnesses. Background Technology

[0002] Cable ties can be used to bundle wire harnesses, such as those used in air conditioners. Figure 6 The cable tie 90 is a plastic product, including a strap body 91 with barbs, a hole seat 92 and a handle 94 at the tail of the strap body. The hole seat has a through hole 93. The strap body is bent and the front end of the strap body passes through the through hole. Because the strap body has barbs, the strap body that passes through the through hole does not reverse, thus serving the function of binding objects. Summary of the Invention

[0003] The technical problem solved by this invention is to provide a mechanical device structure capable of automatically bundling wire harnesses.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automatic cable tie mechanism, comprising a work panel with a cable tie positioning structure, a positioning component disposed near the cable tie positioning structure for positioning the cable ties in the cable tie positioning structure, a strap pulling mechanism disposed below the cable tie positioning structure, and a bending mechanism for bending the strap body toward the cable tie hole seat. The bending mechanism includes an arc-shaped component with one end connected to a rotating shaft, the arc-shaped component being located below the cable tie positioning structure, and a movable stop bar disposed above the cable tie positioning structure, the stop bar being located on the movement trajectory of the upwardly rotating arc-shaped component; the stop bar is equipped with a pressure plate, and the stop bar and the pressure plate are capable of lifting and lowering.

[0005] The working principle of the cable tie machine is as follows: The cable tie is placed in the cable tie positioning structure, with the wire harness to be bundled positioned above and perpendicular to the cable tie. The cable tie placed in the positioning structure is not accurately or stably positioned. The positioning component further positions the cable tie, fixing its tail end to ensure accurate and stable positioning. The pressure plate presses against the middle of the cable tie, providing positioning.

[0006] Driven by the rotating shaft, the arc-shaped component rotates upward, passes through the work panel, and bends the cable tie on the work panel upward. Since the cable tie needs sufficient bending to insert its end into the hole of the cable tie holder, and because the cable tie is made of plastic, it easily slips against the arc-shaped component, making it difficult for the component to bend the cable tie to a sufficient degree. Therefore, this invention includes a stop bar and a pressure plate during the bending process of the cable tie by the arc-shaped component. As the arc-shaped component rotates upward, the stop bar and pressure plate also rise accordingly. Under the constraint of the stop bar and pressure plate, the cable tie bends along the inner wall of the arc-shaped component.

[0007] Afterwards, the stop bar and pressure plate shift, no longer obstructing the curved component, which continues to rotate, causing the end of the belt to pass through the hole in the seat. Then, the end of the belt is pulled downwards by the belt pulling mechanism, and the cable tie secures the power line.

[0008] There are two pressure plates, located to the lower left and lower right of the stop bar. During the rotation of the arc-shaped part, the two pressure plates and the stop bar rise synchronously to restrict the cable tie to the inner wall of the arc-shaped part, so that the cable tie can bend according to the curvature of the arc-shaped part. This prevents the cable tie from slipping on the inner wall of the arc-shaped part and failing to achieve the predetermined bending effect, thus ensuring that the front end of the cable tie can be smoothly inserted into the perforation.

[0009] The stop lever and pressure plate are mounted on a stop lever seat, which is connected to a vertical lifting cylinder, which in turn is connected to the piston of the stop lever cylinder. Driven by the stop lever cylinder, the stop lever seat moves laterally horizontally, positioning the stop lever and pressure plate on the rotation trajectory of the curved component, or retracting the stop lever and pressure plate to the side of the curved component. Driven by the vertical lifting cylinder, the stop lever seat rises and falls, causing the stop lever and pressure plate to rise and fall accordingly.

[0010] One end of the rotating shaft is connected to the arc-shaped component, and the other end of the rotating shaft is equipped with a synchronous pulley, which is connected to the first motor through a synchronous belt.

[0011] A transverse sliding seat is located beside the curved component, and a telescopic spring is mounted on the transverse sliding seat. A roller is located on one side of the transverse sliding seat, and the roller engages in an inclined groove in the track plate. The track plate is connected to a cylinder driving the sliding seat. Driven by the cylinder, the track plate rises, driving the roller to move towards the curved component. The roller causes the transverse sliding seat to move synchronously, and the telescopic spring blocks the rotation trajectory of the curved component. After the stop bar and pressure plate exit the rotation trajectory of the curved component, the telescopic spring intervenes. The curved component continues to rotate, and the telescopic spring, while pressing the cable tie against the inner wall of the curved component, undergoes elastic deformation, allowing the curved component to continue rotating. When the telescopic spring detaches from the curved component due to deformation, the front end of the cable tie can easily pass through the hole.

[0012] The cable tie positioning structure includes a cable tie tail positioning groove on the work panel, and a through hole in the cable tie tail positioning groove that is vertically aligned with the through hole on the cable tie hole seat. Driven by the arc-shaped component, the end of the cable tie is inserted into the through hole, then passes downward through the through hole, that is, downward through the work panel. Afterward, the cable tie pulling mechanism pulls the end of the cable tie.

[0013] The cable tie positioning structure also includes a V-shaped positioning groove, which can position the head of the cable tie. Attached Figure Description

[0028] Combination Figures 1 to 4An automatic cable tie mechanism includes a work panel 10 with a cable tie positioning structure, a positioning component positioned near the cable tie positioning structure to position the cable ties within it, a strap pulling mechanism 20 positioned below the cable tie positioning structure, and a bending mechanism 30 for bending the strap towards the cable tie hole seat. The bending mechanism includes an arc-shaped member 31 with one end connected to a rotating shaft 32, located below the cable tie positioning structure. A movable stop bar 40 is positioned above the cable tie positioning structure, along the trajectory of the upwardly rotating arc-shaped member. The stop bar 40 is equipped with a pressure plate 43, and both the stop bar and the pressure plate are capable of lifting and lowering.

[0029] The working process of the cable tie mechanism for bundling wire harnesses is as follows: The cable tie 90 is located in the cable tie positioning structure, and the positioning component positions the cable tie and fixes its tail. The pressure plate 43 presses against the middle of the cable tie, thus positioning it. Driven by the rotating shaft 32, the arc-shaped component 31 rotates upward, bending the cable tie body 91 on the work panel upward.

[0030] Because the strap body needs sufficient curvature for its end to insert into the through hole 93 of the cable tie seat, and the strap body 91 is made of plastic, it is prone to slipping against the curved part 31, making it difficult for the curved part 31 to bend the strap body to a sufficient degree. Therefore, this invention provides a stop bar 40 and the pressure plate 43 during the bending process of the curved part 31. As the curved part rotates upward, the stop bar and pressure plate 43 also rise accordingly. Under the constraint of the stop bar 40 and pressure plate 43, the strap body bends along the inner wall of the curved part 31.

[0031] Afterwards, the stop bar 40 and pressure plate 43 shift, no longer obstructing the arc-shaped component 31, and the arc-shaped component continues to rotate, causing the end of the belt body 91 to pass through the through hole 93 of the hole seat. The end of the belt body passes downward through the work panel 10. Then, the end of the belt body 91 is pulled downward by the belt body pulling mechanism 20, and the cable tie 90 secures the power line.

[0032] There are two pressure plates 43, located to the lower left and lower right of the stop bar 40. During the rotation of the arc-shaped part 31, the two pressure plates 43 and the stop bar 40 rise synchronously to restrict the cable tie 90 on the inner wall of the arc-shaped part 31, so that the cable tie can bend according to the curvature of the arc-shaped part, avoiding the cable tie 90 from slipping on the inner wall of the arc-shaped part 31 and failing to achieve the predetermined bending effect, so as to ensure that the front end of the cable tie can be smoothly inserted into the perforation.

[0033] The stop lever 40 and pressure plate 43 are mounted on the stop lever seat 42, which is connected to a vertical lifting cylinder 44. The vertical lifting cylinder is connected to the piston of the stop lever cylinder 41. Driven by the stop lever cylinder 41, the stop lever 40 and pressure plate 43 move forward or backward. When moving forward, the stop lever and pressure plate 43 are located on the rotation trajectory of the arc-shaped component 31. When moving backward, the stop lever and pressure plate 43 no longer obstruct the arc-shaped component 31 from continuing to rotate. Driven by the vertical lifting cylinder 44, the stop lever seat 42 rises and falls, and the stop lever 40 and pressure plate 43 rise and fall accordingly.

[0034] One end of the rotating shaft 32 is connected to the arc-shaped component 31, and the other end of the rotating shaft is provided with a synchronous pulley 34, which is connected to the first motor 33 through a synchronous belt 35. The first motor is different from a cylinder; it can pause midway through rotation and then continue rotating to meet the motion requirements of the arc-shaped component 31.

[0035] A transverse sliding seat 36 is provided on the side of the arc-shaped component 31. A telescopic spring 37 is provided on the transverse sliding seat. A roller 361 is provided on one side of the transverse sliding seat. The roller is engaged in the inclined groove of the track plate 362. The track plate is connected to the sliding seat driving cylinder 363. Driven by the sliding seat driving cylinder 363, the track plate 362 rises, driving the roller 361 to move towards the arc-shaped component 31. The roller 361 drives the transverse sliding seat 36 to move synchronously. The telescopic spring 37 blocks the rotation trajectory of the arc-shaped component 31. After the stop bar 40 and the pressure plate 43 exit the rotation trajectory of the arc-shaped component 31, the telescopic spring 37 intervenes. The arc-shaped component 31 continues to rotate. While pressing the cable tie 90 against the inner wall of the arc-shaped component 31, the telescopic spring undergoes elastic deformation, allowing the arc-shaped component 31 to continue rotating. When the telescopic spring 37 detaches from the arc-shaped component 31 due to deformation, the front end of the cable tie can smoothly pass through the hole.

[0036] like Figure 1 The cable tie positioning structure includes a cable tie tail positioning groove 11 provided on the working panel 10, and a through hole 12 provided in the cable tie tail positioning groove, which is vertically aligned with the through hole 93 on the cable tie hole seat 92. Driven by the arc-shaped member 31, the end of the cable tie 91 is inserted into the through hole 93, and then passes downward through the through hole 12, that is, downward through the working panel 10. After that, the cable tie pulling mechanism 20 pulls the end of the cable tie.

[0037] like Figure 4The positioning assembly includes a lifting and lowering pressing module 50, which is connected to a lifting template 52. The lifting template is connected to a lifting cylinder 53. The vertical part 51 of the pressing module can press against the cable tie hole seat 92, and the side wall of the vertical part is vertically aligned with the through hole 93 on the cable tie hole seat. After the worker places the cable tie 90 in the cable tie positioning structure of the work panel 10, the pressing module 50 descends, and the vertical part 51 presses against the cable tie hole seat 92 to fix the tail of the cable tie. The side wall of the vertical part is vertically aligned with the through hole 93 on the cable tie hole seat. Under the action of the arc-shaped member 31, the end of the cable tie 91 contacts the side wall of the vertical part 51 and slides down along the side wall to insert into the through hole 93. Therefore, the vertical part 51 provides conditions for the end of the cable tie 91 to be smoothly inserted into the through hole 93.

[0038] like Figure 1 The cable tie positioning structure also includes a V-shaped positioning groove 13, which can position the head of the cable tie.

[0039] like Figure 3 The belt pulling mechanism 20 includes a pair of drive rollers 21 capable of clamping the belt 91. The pair of drive rollers are mounted on a pair of drive shafts 22, and the drive shafts are provided with a pair of meshing gears 23. Each drive shaft is driven by a second motor 240 via a drive belt 24. The pair of drive rollers clamp and drive the end of the belt 91 downward. The drive belt 24 drives the gears 23 on the drive shafts 22 via a gear set 241.

[0040] A horizontally rotatable cutting blade 25 is located below the work panel 10, passing under the through hole 12 during rotation. The middle of the cutting blade is hinged to the bottom surface of the work panel, one end of the cutting blade is movably connected to the push rod 26, and the other end of the cutting blade is equipped with a cutting edge. The push rod is mounted on the translation module 27, which is connected to the cutting cylinder 28. Driven by the cutting cylinder, the push rod 26 translates, driving the cutting blade 25 to rotate. The cutting edge of the cutting blade passes under the through hole 12, cutting off the belt 91 that is passing downward through the through hole. The cut waste is discharged through the discharge pipe 29.

[0041] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
