[0032] It should be further understood that the term "and / or" used in the present description and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0033] Combination Figure 1 As shown, an embodiment of the present invention provides a zero-cut insulation stripping device for an electric wire end portion, comprising a driving mechanism 1, a zero-cut stripping mechanism 2 and a waste recovery mechanism 3, wherein the driving mechanism 1 comprises a first moving part 11 and a second moving part 12 which can move toward or away from each other; the zero-cut stripping mechanism 2 comprises a plurality of first punching knife assemblies 21 insulatedly mounted on the first moving part 11 and a plurality of second punching knife assemblies 22 insulatedly mounted on the second moving part 12, the plurality of first punching knife assemblies 21 correspond one to one to the plurality of second punching knife assemblies 22, and a zero-cut station 23 and a stripping station 24 are provided between the first punching knife assemblies 21 and the second punching knife assemblies 22; the waste recovery mechanism 3 comprises a plurality of vacuum generating assemblies 31 and a plurality of skin suction pipeline assemblies 32 which are mounted side by side on the driving mechanism 1.

[0034] In this embodiment, the first moving part 11 and the second moving part 12 are symmetrically arranged with the same structure, a plurality of first punching knife assemblies 21 are installed on the first moving part 11, and a plurality of second punching knife assemblies 22 are installed on the second moving part 12. The first punching knife assemblies 21 and the second punching knife assemblies 22 are symmetrically arranged with the same structure. When the first moving part 11 and the second moving part 12 move toward or away from each other, the first punching knife assemblies 21 and the corresponding second punching knife assemblies 22 can be driven to move toward or away from each other.

[0035] Furthermore, a zero-cutting station 23 and a peeling station 24 are provided between each first punching knife assembly 21 and the corresponding second punching knife assembly 22 . It can be understood that the zero-cutting station 23 and the peeling station 24 are formed by the gap between the first punching knife assembly 21 and the second punching knife assembly 22 .

[0036] Specifically, when the wire 5 needs to be zero-cut or stripped, the zero-cut and insulation stripping device at the end of the wire remains in a reset state, that is, the first moving part 11 and the second moving part 12 are away from each other, and the downward conveying mechanism (not shown in the figure) conveys the end of the wire 5 to the corresponding zero-cut station 23 or the corresponding stripping station 24, and then the driving mechanism 1 drives the first moving part 11 and the second moving part 12 to move toward each other, thereby driving the first punching knife assembly 21 and the second punching knife assembly 22 to move toward each other, so as to achieve zero cutting or stripping of the end of the wire 5.

[0037] Preferably, at least two pairs of the first punching knife assembly 21 and the second punching knife assembly 22 of the embodiment of the present invention are arranged (i.e., two first punching knife assemblies 21 and two second punching knife assemblies 22) to form a pair of zero-cutting stations 23 and stripping stations 24, so that the downward conveying mechanism (not shown in the figure) can convey the two end ends of the wire 5 to the corresponding zero-cutting station 23 or stripping station 24 respectively, and perform zero-cutting or stripping on the two end ends of the wire 5 at the same time to improve production efficiency.

[0038] It should be noted that there is no limit to the number of the first punching blade assembly 21 and the second punching blade assembly 22, and a larger number can be provided to improve production efficiency. However, for each first punching blade assembly 21, there must be a corresponding second punching blade assembly 22 to correspond thereto.

[0039] Please refer to Figure 2 As shown, in one embodiment, the first punching knife assembly 21 and the second punching knife assembly 22 each include a knife seat 25, a cutting knife 26, a first skinning knife 27 and a second skinning knife 28, and the cutting knife 26, the first skinning knife 27 and the second skinning knife 28 are installed side by side on the corresponding knife seat 25.

[0040] In this embodiment, a knife seat 25 is installed on both sides of the first moving part 11 and the second moving part 12 , and a cutting knife 26 , a first peeling knife 27 and a second peeling knife 28 are sequentially arranged side by side on the knife seat 25 .

[0041] Specifically, the wire 5 can be placed between any pair of blade heads of the relative cutting knife 26, the relative first stripping knife 27 or the relative second stripping knife 28. When the first moving part 11 and the second moving part 12 move toward each other, the first punching knife assembly 21 and the second punching knife assembly 22 are driven to achieve the function of zero cutting or stripping of the wire 5.

[0042] Combination Figure 1 and Figure 2 In one embodiment, a zero-cutting station 23 is formed between the opposing cutting knives 26, and the stripping station 24 includes a first stripping station 241 and a second stripping station 242 for stripping wires 5 of different wire diameters. The first stripping station 241 is formed between the opposing first stripping knives 27, and the second stripping station 242 is formed between the opposing second stripping knives 28.

[0043] In this embodiment, the cutting knife 26, the first stripping knife 27 and the second stripping knife 28 are different types of knives, and the middle part of their knife heads has a "V"-shaped incision. When the first punching knife assembly 21 and the second punching knife assembly 22 move toward each other, the two relative cutting knives 26 are driven to move toward each other, and the knife heads of the two relative cutting knives 26 are merged, so that when the wire 5 is placed between the two relative cutting knives 26, the wire 5 can be cut; and when the two relative first stripping knives 27 or second stripping knives 28 move toward each other, their relative knife heads are not completely merged, so that when the wire 5 is placed between the two relative first stripping knives 27 or second stripping knives 28, the insulation of the wire 5 can be stripped.

[0044] Please refer to Figure 3 As shown, in one embodiment, the first moving part 11 and the second moving part 12 both include a sliding block 13 and a mounting seat 14, the mounting seat 14 includes an insulating connecting plate 141, a reinforcing connecting plate 142, a knife seat connecting plate 143 and a plurality of T-shaped insulating rings 144, the insulating connecting plate 141, the reinforcing connecting plate 142 and the knife seat connecting plate 143 are all threadedly connected to the sliding block 13 through the T-shaped insulating ring 144, so that the driving mechanism 1 and the zero-cut stripping mechanism 2 are insulated; the driving mechanism 1 also includes a driving member, which is used to drive the two sliding blocks 13 to move toward each other or away from each other.

[0045] In a more specific embodiment, both sides of the mounting seat 14 (i.e., both sides of the knife seat connecting plate 143) are extended outward in the horizontal direction, and a plurality of first punching knife assemblies 21 are detachably mounted on both sides of the corresponding mounting seat 14; a plurality of second punching knife assemblies 22 are detachably mounted on both sides of the corresponding mounting seat 14; a device with a core wire cut detection function (not shown in the figure) is provided between the first punching knife assembly 21 and the second punching knife assembly 22, which is used to detect whether the stripping knife contacts or damages the core wire of the wire 5 when the wire 5 is stripped; when the core wire cut detection device (not shown in the figure) detects that the stripping knife contacts or damages the core wire of the wire 5 when the wire 5 is stripped, the clamping jaws of the downward conveying mechanism (not shown in the figure) release the wire 5, and then the damaged wire 5 is blown into the defective product box by the downward blowing mechanism (not shown in the figure).

[0046] Please refer to Figure 4 As shown, in one embodiment, the driving member includes a driving mounting shell 17, a motor 15 and a bidirectional screw 16, the motor 15 is mounted at one end of the driving mounting shell 17, one end of the bidirectional screw 16 is coaxially connected to the output shaft of the motor 15, and the other end of the bidirectional screw 16 is mounted at the other end of the driving mounting shell 17, the first moving part 11 and the second moving part 12 are slidably assembled in the driving mounting shell 17 and are respectively threadedly connected to the two ends of the bidirectional screw 16.

[0047] In this embodiment, the opposite threads of the bidirectional screw 16 are respectively arranged at the two ends of the bidirectional screw 16, the motor 15 is installed at one end of the driving mounting shell 17, the output shaft of the motor 15 is coaxially connected to one end of the bidirectional screw 16, and the other end of the bidirectional screw 16 is rotatably installed with the other end of the driving mounting shell 17, so that the bidirectional screw 16 can be driven to rotate when the motor 15 rotates.

[0048] Furthermore, threaded through holes matching opposite threads on the bidirectional screw 16 are provided in the sliding blocks 13 of the first moving part 11 and the second moving part 12, so that the first moving part 11 and the second moving part 12 are slidably assembled in the drive mounting shell 17 and are respectively threadedly connected to the two ends of the bidirectional screw 16. When the motor 15 rotates forward or reversely to drive the bidirectional screw 16 to rotate, the first moving part 11 and the second moving part 12 can move toward or away from each other on the bidirectional screw 16.

[0049] It is understandable that the sliding blocks 13 of the first moving part 11 and the second moving part 12 are also provided with sliding grooves, and the two sliding blocks 13 are slidably installed on both sides of the inside of the driving installation shell 17 through the sliding grooves to reduce the resistance of the two sliding blocks 13 when sliding.

[0050] Please refer to Figure 5 As shown, in one embodiment, it also includes a mounting substrate 4, on which a position detector 41 is mounted, and a sensing sheet 111 is provided on the first moving part 11 or the second moving part 12. When the first moving part 11 and the second moving part 12 slide in opposite directions, the sensing sheet 111 moves to the detection port of the position detector 41 and triggers the detector to prompt that the sliding is in place.

[0051] In the present embodiment, the device for zero-cutting and stripping insulation at the end of a wire further comprises a mounting substrate 4, on which a drive mounting shell 17 is mounted; further, a position detector 41 (i.e., an optical coupler detector) is mounted on the mounting substrate 4, and a sensing piece 111 which can trigger the position detector 41 is mounted on the first moving part 11 or the second moving part 12. Specifically, the sensing piece 111 can be arranged on an insulating connecting plate 141 or a reinforcing connecting plate 142. When the sliding blocks 13 of the first moving part 11 and the second moving part 12 move in opposite directions, the sensing piece 111 on the insulating connecting plate 141 or the reinforcing connecting plate 142 can be driven to move, and then the sensing piece 111 can move to the sensing port of the position detector 41. The position detector 41 prompts the first moving part 11 and the second moving part 12 to slide into place, thereby controlling the sliding stroke of the first moving part 11 and the second moving part 12 to avoid the sliding stroke being too long and affecting the processing efficiency.

[0052] Please refer to Figure 5 and Figure 6As shown, in one embodiment, the waste recovery mechanism 3 is provided with a plurality of vacuum generating assemblies 31 and a plurality of skin suction pipe assemblies 32, and the suction ends of the plurality of skin suction pipe assemblies 32 respectively correspond to the zero-cutting stations 23 and the peeling stations 24 between the plurality of relative first punching knife assemblies 21 and the second punching knife assemblies 22.

[0053] In this embodiment, the waste recovery mechanism 3 is used to recover the waste generated during zero cutting and stripping of the ends of the electric wires 5. The waste recovery mechanism 3 includes a plurality of vacuum generating components 31 and a plurality of skin suction pipeline components 32. The suction end of each skin suction pipeline component 32 corresponds to the zero cutting station 23 and the stripping station 24 between each relative first punching knife component 21 and the second punching knife component 22, so that the waste generated during zero cutting and stripping of the electric wires 5 corresponds to the suction end of the skin suction pipeline component 32, thereby the waste is recovered into the waste box along the internal channels of the skin suction pipeline component 32 and the vacuum generating component 31 through the suction force provided by the vacuum generating component 31.

[0054] In a specific embodiment, a fixing plate 42 is provided on the mounting base plate 4 , and a plurality of skin suction pipeline assemblies 32 are horizontally installed side by side on the fixing plate 42 .

[0055] In this embodiment, the fixed plate 42 is extended in the horizontal direction of the mounting base plate 4, and a plurality of suction pipe assemblies 32 can be installed side by side on the fixed plate 42. The suction end of each suction pipe assembly 32 corresponds to the zero cutting position and the peeling position, thereby ensuring that the waste is not easily scattered when the waste recovery mechanism 3 recovers the waste.

[0056] It can be understood that the horizontal direction is Figure 1 Left and right directions shown.

[0057] Please refer to Figure 6 As shown, in a more specific embodiment, the vacuum generating assembly 31 includes a vacuum core 311, a vacuum jacket 312, a vacuum upper sleeve 313 and a plurality of O-rings 314; the skin suction pipeline assembly 32 includes a skin suction lock 321, a hose 322, a skin suction tube 323 and a skin suction nozzle 324, and the skin suction nozzle 324 is provided with a suction hole, and the suction hole corresponds to the zero-cutting station 23 and the peeling station 24 between the first punching knife assembly 21 and the second punching knife assembly 22. The skin suction nozzle 324 and The suction tube 323 is installed on the fixing plate 42, one end of the hose 322 is connected to the suction tube 323, the other end of the hose 322 is connected to one end of the suction lock 321, the other end of the suction lock 321 is threadedly connected to one end of the vacuum upper sleeve 313 and sealed with an O-ring 314, the other end of the vacuum upper sleeve 313 is threadedly connected to the vacuum outer jacket 312 and sealed with an O-ring 314, and the vacuum core 311 is installed inside the vacuum outer jacket 312 and sealed with an O-ring 314.

[0058] In this embodiment, when the vacuum generating assembly 31 is turned on, the generated suction force is used to suck the waste wire 5 at the zero cutting position and the stripping position from the suction hole into the skin suction nozzle 324, and then enter the internal channel of the skin suction pipeline assembly 32, and then reach the internal channel of the vacuum generating assembly 31 through the internal channel of the skin suction pipeline assembly 32, and finally recovered into the waste box, thereby avoiding waste from polluting the working environment and keeping it clean.

[0059] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention.
