Description
Technical Field
[0001] This invention relates to the field of automatic strapping technology, and in particular to a strapping device and strapping equipment. Background Technology
[0002] Cable ties are commonly used in the packaging of products, such as to bundle pliers and nameplates together. Currently, this manual bundling is inefficient. While automated cable tying systems exist, these systems often involve numerous drive components and have complex structures. Summary of the Invention
[0003] This invention provides a strapping device and a strapping equipment, the purpose of which is to improve the efficiency of cable ties and reduce the structural complexity of the strapping device.
[0004] To achieve the above objectives, the present invention provides a binding device, comprising:
[0005] A bending belt assembly includes a mounting plate, a bending belt plate, and a steering protrusion. The mounting plate has an interconnected receiving groove and an opening. The receiving groove is used to receive a portion of the toothed strip of a cable tie, and the opening is used to receive the tie end of the cable tie. The bending belt plate is rotatably connected to the mounting plate and is configured to bend the toothed strip. The steering protrusion remains relatively stationary with respect to the bending belt plate.
[0006] A first driving element is configured to drive the curved belt assembly to move;
[0007] A guide post extends along the moving direction of the bending belt assembly. The surface of the guide post that abuts against the steering protrusion is a guide surface. When the bending belt assembly moves, the guide surface can guide the steering protrusion to rotate, thereby driving the bending belt plate to rotate and bending the toothed belt strip.
[0008] A reversing plate has a reversing groove, on which a component to be bundled is disposed. The reversing groove has an inlet and an outlet, with the inlet and outlet facing the same direction. The bent portion of the toothed belt faces the inlet, so that the bent toothed belt can enter the reversing groove from the inlet, reverse direction within the reversing groove, exit from the outlet, and pass through the binding hole, so that the cable tie can bundle the component to be bundled.
[0009] In one embodiment, the mounting plate includes a mounting sub-plate and a rotating plate. The rotating plate is vertically disposed below the mounting sub-plate. The mounting sub-plate and the rotating plate enclose the receiving groove. The mounting sub-plate has the opening. The rotating plate is rotatably connected to the mounting sub-plate so that when the bent portion of the toothed strip passes through the slit, the unbent portion of the toothed strip can disengage from the receiving groove.
[0010] In one embodiment, the mounting plate includes a first torsion spring, which is connected to both the rotating plate and the mounting sub-plate, so that when the rotating plate rotates relative to the mounting sub-plate, the rotating plate can return to its original position.
[0011] In one embodiment, the distance between the rotation center of the steering bump and the guide surface in the horizontal direction is a preset distance. When the bending belt assembly moves, the preset distance switches between a maximum value and a minimum value to make the steering bump rotate.
[0012] In one embodiment, the guide surface includes a rotating surface and a fixed surface connected to each other. The rotating surface is disposed above the fixed surface. When the steering protrusion abuts against the rotating surface, the preset distance switches between the maximum value and the minimum value. When the steering protrusion abuts against the fixed surface, the preset distance is the minimum value.
[0013] In one embodiment, the bending belt assembly includes a second torsion spring, which is connected to the mounting plate and the steering lug, respectively, so that when the preset distance switches from the minimum value to the maximum value, the steering lug can rotate back to its original position.
[0014] In one embodiment, the strapping device includes a strap assembly disposed on the first driving member. The strap assembly includes an active roller and a passive roller. The active roller can drive the passive roller to rotate. The active roller and the passive roller enclose a strapping space capable of lifting the strap. The projection of the opening on the mounting plate and the projection of the strapping space on the mounting plate at least partially coincide, so that when the bent portion of the toothed strip passes through the strap opening, the bent portion of the toothed strip can enter the strapping space.
[0015] In one embodiment, the pull belt assembly includes a frame disposed on the first drive member, and both the active roller and the passive roller are rotatably connected to the frame. The frame has an elongated hole through which the passive roller passes, so that the size of the pull belt space can be adjusted.
[0016] In one embodiment, the bending belt assembly includes a guide block connected below the mounting plate, the guide block being disposed on the side of the opening away from the toothed belt strip.
[0017] A second aspect of the present invention provides a strapping device, comprising:
[0018] The binding device according to any of the foregoing embodiments;
[0019] The first feeding device is configured to push the toothed strip of the cable tie into the receiving groove and push the cable tie end into the opening;
[0020] The second feeding device is configured to transport the nameplate onto the reversing plate.
[0021] The above-described solution of the present invention has the following beneficial effects:
[0022] In this embodiment, guided by the guide surface, the steering protrusion can rotate, thereby causing the bending plate, which remains relatively stationary with respect to the steering protrusion, to also rotate. This allows the bending plate to bend the toothed belt strip protruding from the receiving groove. The bent portion of the toothed belt strip faces the entrance of the reversing groove, so that when the bent portion of the toothed belt strip moves towards the reversing groove, the bent portion can complete the reversal within the reversing groove and exit through the outlet, then re-enter the binding hole to automatically complete the cable tie binding operation. The binding device of this application can automatically complete the cable tie binding operation. Compared with manual binding using cable ties, the binding device has higher binding efficiency, thereby improving product production efficiency. Furthermore, the binding device of this application has a relatively simple structure, using only one first driving member to complete the cable tie binding operation.
[0023] Other beneficial effects of the present invention will be described in detail in the following detailed description section. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0033] This application provides a binding device 100 for replacing manual binding of cable ties 500. For details, please refer to... Figure 1The strapping device 100 includes a bending belt assembly 1, a first driving component 2, a guide post 3, and a reversing plate 4.
[0034] Please see Figure 1 and Figure 2 The bending belt assembly 1 includes a mounting plate 11, a bending belt plate 12, and a steering protrusion 13. The bending belt assembly 1 can be made of a material with certain strength and rigidity, such as metal. The mounting plate 11 serves as a structure for accommodating the cable tie 500, and may have interconnected receiving grooves 11a and openings 11b. The receiving groove 11a is used to accommodate a portion of the toothed strip 501 of the cable tie 500, and the opening 11b is used to accommodate the tie end 502 of the cable tie 500. For example, please refer to... Figure 1 The portion of the toothed belt strip 501 located outside the receiving groove 11a, i.e., the suspended portion of the toothed belt strip 501, can extend approximately horizontally by its own strength. The bending plate 12 is rotatably connected to the mounting plate 11, and the bending plate 12 is configured to bend the toothed belt strip 501. For example, please refer to... Figure 1 and Figure 2 The bending plate 12 is located on the side of the receiving groove 11a opposite to the opening 11b, so that the suspended portion of the toothed belt 501 can be bent during the rotation of the bending plate 12 relative to the mounting plate 11. The steering protrusion 13 remains relatively stationary with the bending plate 12, that is, the steering protrusion 13 can rotate synchronously with the bending plate 12. For example, please refer to... Figure 1 and Figure 2 The bending plate 12 and the steering protrusion 13 are rotatably connected to the mounting plate 11 via a rotating shaft. The rotating shaft passes through the mounting plate 11 and can rotate relative to the mounting plate 11. The bending plate 12 and the steering protrusion 13 are fixedly connected to opposite sides of the rotating shaft along its own axial direction, so that the bending plate 12 and the steering protrusion 13 can rotate relative to the mounting plate 11 and remain relatively stationary.
[0035] Please see Figure 1 The first drive element 2 is configured to drive the bending belt assembly 1 to move. For example, the first drive element 2 can be a cylinder, and the first drive element 2 is connected to the mounting plate 11 to drive the mounting plate 11 to move up and down in the vertical direction.
[0036] Please see Figure 1 and Figure 3The guide post 3 extends along the moving direction of the bending assembly 1. For example, the guide post 3 extends vertically, with its first end fixed along its own axial direction and its second end suspended. The guide post 3 can be made of a material with certain strength and rigidity, such as metal. The guide post 3 can abut against the steering protrusion 13, and the surface of the guide post 3 that abuts against the steering protrusion 13 is a guide surface 31, used to guide the rotation of the steering protrusion 13. When the bending assembly 1 moves, the guide surface 31 can guide the steering protrusion 13 to rotate, thereby driving the bending plate 12 to rotate, thus bending the toothed belt 501. For example, please refer to... Figure 3 The bending belt assembly 1 moves downward in the vertical direction under the drive of the first driving member 2, and the steering protrusion 13 rotates under the guidance of the guide surface 31, for example, as shown in the figure. Figure 3 As shown, clockwise rotation keeps the bending plate 12 and the steering protrusion 13 relatively stationary, allowing the bending plate 12 to also rotate clockwise, thus bending the suspended portion of the toothed belt 501 downwards. For example, see... Figures 1-3 The bending plate 12 and the steering protrusion 13 are arranged at intervals along the extension direction of the rotation axis to reduce the possibility of the guide post 3 interfering with the bending of the cable tie 500.
[0037] Please see Figure 1 and Figure 3 The reversing plate 4 has a reversing groove 41. A component to be bundled is provided on the reversing plate 4; the component to be bundled can be a nameplate 700 and pliers 600. The cross-section of the reversing groove 41 along its extension direction can be configured as an arc shape. The reversing groove 41 has an inlet 411 and an outlet 412, with the inlet 411 and outlet 412 facing the same direction. The bent portion of the toothed belt strip 501 faces the inlet 411, allowing the bent toothed belt strip 501 to enter the reversing groove 41 from the inlet 411, reverse direction within the reversing groove 41, exit from the outlet 412, and pass through the cable tie 502, so that the cable tie 500 can bundle the nameplate 700 and pliers 600. For example, please refer to... Figure 3 The bent portion of the toothed strip 501 faces the inlet 411, so that when the bending assembly 1, driven by the first drive member 2, moves the cable tie 500 downwards in the vertical direction, the bent toothed strip 501 can enter the arc-shaped reversing groove 41 through the inlet 411, complete the reversal within the reversing groove 41, and then exit from the outlet 412. As the bending assembly 1 continues to move downwards, the toothed strip 501 exiting from the outlet 412 can be threaded into the binding opening 502 to complete the binding operation of the cable tie 500. For example, please refer to... Figure 1The binding device 100 of this application can bind the nameplate 700 to the pliers 600. The size of the nameplate 700 in the extension direction of the reversing groove 41 is slightly smaller than the size of the reversing groove 41 in its own extension direction. The nameplate 700 is located in the middle of the reversing groove 41 so as not to cover the inlet 411 and outlet 412 of the reversing groove 41. It also allows the cable tie 500 to pass through the inlet 411 and the outlet 412 to bind the nameplate 700 to the pliers 600.
[0038] In this embodiment, guided by the guide surface 31, the steering protrusion 13 can rotate, thereby causing the bending plate 12, which remains relatively stationary with respect to the steering protrusion 13, to also rotate. This allows the bending plate 12 to bend the toothed strip 501 protruding from the receiving groove 11a. The bent portion of the toothed strip 501 faces the inlet 411 of the reversing groove 41, so that when the bent portion of the toothed strip 501 moves towards the reversing groove 41, the bent portion of the toothed strip 501 can complete the reversal within the reversing groove 41 and pass through the outlet 412, and then pass into the binding opening 502, thus automatically completing the binding operation of the cable tie 500. The binding device 100 of this application can automatically complete the binding operation of the cable tie 500. Compared with manual binding using the cable tie 500, the binding efficiency of the binding device 100 is higher, thereby improving the production efficiency of the product. Furthermore, the binding device 100 of this application has a relatively simple structure, and the binding operation of the cable tie 500 can be completed using only one first driving member 2.
[0039] In one embodiment, please refer to Figure 2 The mounting plate 11 includes a mounting sub-plate 111 and a rotating plate 112. The rotating plate 112 is vertically positioned below the mounting sub-plate 111. The mounting sub-plate 111 and the rotating plate 112 form a receiving groove 11a, and the mounting sub-plate 111 has an opening 11b. The rotating plate 112 is rotatably connected to the mounting sub-plate 111 so that when the bent portion of the toothed strip 501 passes through the binding hole 502, the unbent portion of the toothed strip 501 can detach from the receiving groove 11a, thereby automatically binding the unbent portion of the toothed strip 501 to the pliers 600 and the nameplate 700 without manual removal of the unbent portion of the toothed strip 501 from the receiving groove 11a, which improves the automation level of the binding device 100. For example, please refer to... Figure 2 The rotating plate 112 can rotate relative to the mounting sub-plate 111 with the extension direction of the cable tie 500 as the rotation axis. When the bent part of the toothed strip 501 passes through the tying opening 502, the toothed strip 501 can form a binding space. As the binding space gradually decreases, the part of the toothed strip 501 located in the receiving groove 11a can deform, so as to force the rotating plate 112 to rotate relative to the mounting sub-plate 111, so that the part of the toothed strip 501 located in the receiving groove 11a can be detached from the receiving groove 11a more smoothly.
[0040] In one embodiment, the mounting plate 11 includes a first torsion spring (not shown). The first torsion spring is connected to both the rotating plate 112 and the mounting sub-plate 111, so that when the rotating plate 112 rotates relative to the mounting sub-plate 111, the first torsion spring can store the rotational potential energy of the rotating plate 112. Under the action of the elastic restoring force of the first torsion spring, the rotating plate 112 can automatically rotate back to its original position for the next binding operation of the cable tie 500.
[0041] In one embodiment, please refer to Figure 3 The distance between the rotation center of the steering protrusion 13 and the guide surface 31 in the horizontal direction is a preset distance. When the belt bending assembly 1 moves, the preset distance switches between a maximum and a minimum value to cause the steering protrusion 13 and the belt bending plate 12 to rotate, thereby bending the toothed belt strip 501. For example, please refer to... Figure 3 The bending belt assembly 1 moves downward in the vertical direction under the drive of the first driving member 2, and the preset distance gradually changes from a maximum value to a minimum value, so that the steering protrusion 13 rotates under the guidance of the guide surface 31. For example, it can be like this: Figure 3 As shown, the bending plate 12 and the steering protrusion 13 remain relatively stationary when rotated clockwise, so that the bending plate 12 can also rotate clockwise to bend the suspended portion of the toothed belt 501 downward.
[0042] In one embodiment, please refer to Figure 3 The guide surface 31 includes a rotating surface 311 and a fixed surface 312 connected to each other. The rotating surface 311 is disposed above the fixed surface 312. When the steering protrusion 13 abuts against the rotating surface 311, the preset distance switches between a maximum value and a minimum value. For example, the rotating surface 311 can be a curved surface, such as an arc surface, so that when the steering protrusion 13 moves downward in the vertical direction, the preset distance gradually changes from a maximum value to a minimum value, thereby forcing the steering protrusion 13 to rotate. When the steering protrusion 13 abuts against the fixed surface 312, the preset distance is at its minimum value. For example, the rotating surface 311 can be a plane, so that when the steering protrusion 13 moves downward in the vertical direction, the preset distance remains at its minimum value. In this embodiment, the rotating surface 311 is located above the fixed surface 312, so that when the bending assembly 1 moves downward in the vertical direction, the bending plate 12 can bend the toothed strip 501 protruding from the receiving groove 11a as early as possible, so that the toothed strip 501 can be bent before entering the inlet 411, thereby increasing the success rate of the bent part of the toothed strip 501 entering the inlet 411.
[0043] In one embodiment, please refer to Figures 1-3The strapping device 100 includes a pull strap assembly 5. The pull strap assembly 5 is mounted on the first drive member 2 so that it can move synchronously with the mounting plate 11 in the vertical direction. The pull strap assembly 5 includes a drive roller 51 and a driven roller 52. The drive roller 51 is rotatable under the drive of a motor or cylinder, so that the drive roller 51 can drive the driven roller 52 to rotate. The drive roller 51 and the driven roller 52 enclose a pull strap space 51a capable of lifting the cable tie 500. The projection of the opening 11b on the mounting plate 11 at least partially overlaps with the projection of the pull strap space 51a on the mounting plate 11, so that when the bent portion of the toothed strip 501 passes through the closure 502, the bent portion of the toothed strip 501 can enter the pull strap space 51a, and under the pull of the drive roller 51 and the driven roller 52, the cable tie 500 can be securely strapped. For example, the drive roller 51 and the driven roller 52 are arranged at intervals. For example, when the toothed belt 501 exits from the outlet 412, it enters the pulling space 51a after passing through the tie 502. The size of the pulling space 51a in the thickness direction of the tie 500 is slightly smaller than the thickness of the tie 500, so that the active roller 51 and the passive roller 52 can undergo small deformation to provide sufficient friction to the toothed belt 501, thereby enabling the active roller 51 and the passive roller 52 to pull the toothed belt 501.
[0044] In one embodiment, please refer to Figure 2 The pull strap assembly 5 includes a frame 53. The frame 53 is mounted on the first drive member 2. Both the driving roller 51 and the driven roller 52 are rotatably connected to the frame 53. The frame 53 has an elongated hole 53a. For example, the elongated hole 53a can extend along the extension direction of the cable tie 500. The driven roller 52 passes through the elongated hole 53a so that the size of the pull strap space 51a can be adjusted, i.e., the size of the pull strap space 51a can be adjusted according to the thickness of the toothed strip 501, so that the pull strap assembly 5 can be adapted to toothed strips 501 of various thicknesses, thereby improving the applicability of the pull strap assembly 5. For example, please refer to... Figure 2 The pull belt assembly 5 may also include an elastic element 54, which may be a spring. The elastic element 54 is disposed in the elongated hole 53a, with one end of the elastic element 54 abutting against the passive roller 52 and the other end abutting against the frame 53, so that the size of the pull belt space 51a can be adjusted according to the thickness of the toothed belt strip 501.
[0045] In one embodiment, please refer to Figure 1 and Figure 2The bending strap assembly 1 includes a guide block 14, which is connected to the lower part of the mounting plate 11. The guide block 14 is located on the side of the opening 11b away from the toothed strap 501, so that when the toothed strap 501 approaches the ties 502 located in the opening 11b, the guide block 14 can reduce the possibility that the toothed strap 501 will deviate and fail to align with the ties 502, which is beneficial to improving the success rate of the strapping device 100 in completing the strapping operation of the cable ties 500.
[0046] In one embodiment, please refer to Figures 1-3 The bending strap assembly 1 includes a second torsion spring 15, which is connected to the mounting plate 11 and the steering protrusion 13, respectively, so that when the preset distance switches from a minimum value to a maximum value, the steering protrusion 13 can rotate back to its original position to perform the next strapping operation 500. For example, when the mounting plate 11 moves downward in the vertical direction, the steering protrusion 13 rotates, and the second torsion spring 15 stores the rotational potential energy of the steering protrusion 13. When the mounting plate 11 moves upward in the vertical direction, the steering protrusion 13 can automatically and gradually rotate back under the action of the elastic restoring force of the second torsion spring 15, so that the steering protrusion 13 always abuts against the guide surface 31.
[0047] In one embodiment, please refer to Figure 1 and Figure 3 The reversing plate 4 has positioning pins 42, which are configured to position the nameplate 700 and the pliers 600 to facilitate rapid positioning of the nameplate 700 and the pliers 600. For example, when the nameplate 700 is loaded onto the reversing plate 4, the nameplate 700 can be quickly positioned to a convenient binding area by relying on the two spaced positioning pins 42, which helps to improve the efficiency of the binding device 100 in binding the nameplate 700 and the pliers 600.
[0048] Please see Figure 4 The second aspect of this application provides a strapping device, including the strapping device 100, the first feeding device 200, and the second feeding device 300 described in the foregoing embodiments. For example, the strapping device further includes a frame 400, and the strapping device 100, the first feeding device 200, and the second feeding device 300 are all disposed at preset positions on the frame 400 to cooperate with each other to achieve automatic feeding and automatic strapping.
[0049] The first feeding device 200 is configured to push the toothed strip 501 of the cable tie 500 into the receiving groove 11a and push the tie end 502 of the cable tie 500 into the opening 11b to complete the automatic feeding of the cable tie 500. The second feeding device 300 is configured to transport the nameplate 700 onto the reversing plate 4 to complete the automatic feeding of the nameplate 700.
[0050] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
