Description

Technical Field

[0001] The invention relates to the technical field of wire stripping equipment, and in particular to an automatic wire stripping device and a wire stripping method. Background Art

[0002] Steel core aluminum stranded wire is a commonly used wire material for power transmission lines. The steel core mainly plays a role in increasing strength, while the aluminum stranded wire is usually responsible for transmitting electrical energy. Specifically, Figure 1 As shown in the figure, the dotted circle marks the outer sheath close to the steel core, the steel core is located inside the outer sheath, and the rest of the outer sheath is located outside the outer sheath. The equipment used with it is usually a tension clamp and a connecting tube. When assembling the steel core aluminum stranded wire with the tension clamp or the connecting tube, the outer aluminum wire of the steel core aluminum stranded wire needs to be peeled off first, so as to expose the inner steel core and crimp it with the steel anchor assembly of the tension clamp or the connecting tube.

[0003] In the prior art, the stripping of steel core aluminum stranded wire is usually done manually, because the inner steel core must not be damaged during stripping, so as to avoid stress concentration at the damaged part of the steel core, thereby reducing the strength of the steel core and bringing safety hazards to the transmission line. Due to the lack of corresponding automated construction equipment for this step, it is always difficult to realize the full process of automated crimping of tension clamps, joint pipes, etc. Summary of the invention

[0004] The technical problem to be solved by the present invention is that steel core aluminum stranded wire is manually stripped in the prior art, and the purpose is to provide an automatic wire stripping device and a wire stripping method to solve the above problem.

[0005] The present invention is achieved through the following technical solutions:

[0006] In a first aspect, the present invention provides an automatic wire stripping device, comprising a wire feeding module, a wire cutting module and a wire stripping module;

[0008] The wire cutting module is used to cut the outer sheath of the wire;

[0009] The stripping module is used to strip off the remaining outer cladding and retain the core layer by rotation.

[0010] In one possible design, the wire stripping module includes a support, a separation unit, a stripping unit, and a first drive unit;

[0011] The support is connected to the separation unit through the first driving unit. Accordingly, the first driving unit is arranged on the support, and the output end of the first driving unit is connected to the separation unit.

[0012] The separation unit is used to separate the outer sheath and the core layer of the wire, and the stripping unit is arranged on the separation unit and is used to disconnect the outer sheath and the core layer of the wire;

[0013] Correspondingly, when the first driving unit drives the separation unit to rotate, the stripping unit follows and causes the outer sheath and the core layer of the wire to be broken and separated.

[0014] In one possible design, the separation unit includes a separation cone and a separation thorn. The separation cone is constructed as a hollow structure and has two opposite ends. The large end of the separation cone is connected to the first drive unit, and the small end of the separation cone is constructed as a core layer entrance connected to the hollow structure.

[0016] In a possible design, the wire cutting module includes a linear module and a wire cutting pliers, wherein the wire cutting pliers are slidably disposed on the linear module and are used to cut the outer sheath of the wire.

[0017] In one possible design, the wire cutter includes a housing, a first blade, a second blade, a second drive unit, and an identification unit;

[0018] The housing is slidably arranged on the linear module, and a shearing hole is arranged on the housing. Accordingly, the first blade and the second blade are arranged on the housing and are arranged opposite to each other with the shearing hole as the center.

[0019] The second driving unit is connected to at least one of the first blade and the second blade so as to make the first blade and the second blade move closer to or separate from each other; the identification unit is arranged on the housing and is used to identify the wire.

[0020] In one possible design, one of the first blade and the second blade is configured as a fixed blade fixed on the outer shell, and the other is configured as a movable blade connected to the second drive unit and slidably disposed on the outer shell. Accordingly, when the wire is passed through the shearing hole, the movable blade slides along the shearing hole and shears the wire.

[0021] In one possible design, the wire feeding module includes a base, a third drive unit, a gripper, a pulley, a fourth drive unit, and a guide rail;

[0022] A third driving unit is provided on the base, and the third driving unit has two opposite output ends. Two clamping hands are provided and are respectively connected to the output ends of the third driving unit. Accordingly, the two clamping hands are arranged opposite to each other and are used to clamp the wire.

[0023] The pulley and the fourth driving unit are respectively arranged on the base, the guide rail is located outside the base and parallel to the linear module, the pulley is slidably arranged on the guide rail, and the fourth driving unit is used to drive the base to slide reciprocatingly along the guide rail.

[0024] In a possible design, a rack parallel to the guide rail is provided outside the guide rail, and the output end of the fourth drive unit is connected to a transmission gear, and correspondingly, the transmission gear meshes with the rack.

[0025] In a second aspect, the present invention provides an automatic wire stripping method based on the automatic wire stripping device, comprising the following steps:

[0026] S100: device initialization;

[0027] S200: The wire is fed into the wire feeding module; the wire feeding module starts and clamps the wire through the clamping hand;

[0028] S300: The wire feeding module feeds the wire until the wire cleaver recognizes the wire; at least one of the wire feeding module and the wire cleaver moves until the wire cleaver is located at the wire cutting position;

[0029] S400: The wire cutter cuts the wire until a groove is left on the innermost outer sheath of the wire;

[0030] S500: The wire feeding module feeds the wire until the outer sheath and the core layer of the wire are separated by the wire stripping module;

[0031] S600: The stripping module starts and separates the outer layer and core layer of the wire by rotation;

[0032] S700: The stripping module stops, and the wire feeding module and the wire cutter are reset respectively until the wire reaches the sampling position; the wire is removed;

[0033] In S400, the depth of the groove is not less than 1 / 3 of the thickness of the innermost outer cladding layer; if the wires are processed in batches, S800 is also included: S200-S700 are repeated until all the wires are processed.

[0034] Compared with the prior art, the present invention has the following advantages and beneficial effects:

They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the scope of protection of the present invention.

[0053] Embodiment 1:

[0054] like Figure 1-Figure 6 As shown, an automatic wire stripping device includes a wire feeding module 100, a wire cutting module 200 and a wire stripping module 300;

[0055] The wire feeding module 100 is used to convey the wire so that the wire moves back and forth;

[0056] The wire cutting module 200 is used to cut the outer sheath of the wire;

[0057] The wire stripping module 300 is used to strip off the remaining outer cladding and retain the core layer by rotation.

[0058] For wires, such as steel-core aluminum stranded wire, the axis is a steel core layer, and the core layer is wrapped with several layers of outer sheaths made of aluminum. The purpose of wire stripping is to peel the outer sheaths from the core layer.

[0059] In the automatic wire stripping device, a stripping processing line is formed by the cooperation of the wire feeding module 100, the wire cutting module 200 and the wire stripping module 300, wherein the wire feeding module 100 enables the wire to reciprocate to realize the feeding of the wire. Specifically, when the wire moves in a first direction, it cooperates with the wire cutting module 200 and the wire stripping module 300 to realize the stripping of the outer sheath and the core layer of the wire. When the wire moves in a second direction, the wire is reset and disassembled to prepare for the next wire stripping operation. It is easy to understand that the first direction and the second direction are opposite to each other.

[0060] When there are many outer cladding layers, the overall thickness of the outer cladding is large, the peeling is difficult, and the core layer is easily damaged during peeling. Therefore, the outer cladding located outside is directly cut off by the cutting module 200, and this part of the outer cladding will automatically fall off, leaving only at least one outer cladding layer located outside the core layer. In this case, it can avoid the cutting of the cutting module 200 from damaging the core layer, ensuring that the core layer can work normally later, and greatly reduce the number of outer cladding layers, reduce the thickness, and reduce the difficulty of peeling.

[0061] When the cutting module 200 is sheared, generally only one outer cladding layer is left. If necessary, if the thickness of the outer cladding layer is small, more outer cladding layers may be left to ensure that the cutting module 200 does not damage the core layer.

[0062] The wire stripping module 300 is used to strip the core layer and the remaining outer cladding layer, so as to completely strip the outer cladding layer and the core layer, so that only the core layer is left at the end of the wire, so as to facilitate the next step of processing.

[0063] During operation, the staff feeds the wire into the wire feeding module 100 and starts the automatic wire stripping device. After the automatic wire stripping device is started, the wire feeding module 100 conveys the wire to the wire cutting module 200, and the wire cutting module 200 shears the outer sheath. After shearing, the wire feeding module 100 feeds the wire again, and the wire moves to the wire stripping module 300, and the wire stripping module 300 peels the outer sheath and core layer of the wire by rotation. After the stripping is completed, the automatic wire stripping device is reset, and the staff can remove the wire. If batch processing is performed, the staff can load the wire into the wire feeding module 100.

[0064] Based on this, the automatic wire stripping device is used to replace manual operation to realize the automation of wire stripping, which helps to improve the efficiency of wire stripping, reduces the influence of human factors on the quality of wire stripping, and improves the quality of wire stripping.

[0065] It is easy to understand that, in addition to the steel core aluminum stranded wire exemplified above, the automatic wire stripping device can also be used for wire stripping operations of any suitable existing wires.

[0066] In a possible implementation, the wire stripping module 300 includes a support 310, a separation unit 320, a stripping unit 330 and a first driving unit 340;

[0067] The support 310 is connected to the separation unit 320 via the first driving unit 340. Accordingly, the first driving unit 340 is disposed on the support 310, and the output end of the first driving unit 340 is connected to the separation unit 320.

[0068] The separation unit 320 is used to separate the outer cladding and the core layer of the wire, and the stripping unit 330 is disposed on the separation unit 320 and is used to disconnect the outer cladding and the core layer of the wire;

[0069] Accordingly, when the first driving unit 340 drives the separation unit 320 to rotate, the stripping unit 330 follows and causes the outer cladding and the core layer of the wire to be broken and separated.

[0070] Based on the above design, the separation unit 320 is used to separate the outer layer and the core layer of the wire. Most of the outer layer has been cut off, and there is a small amount of adhesion between the remaining outer layer and the core layer, so the two can be easily separated without damaging the core layer. As the stripping unit 330 rotates, the remaining outer layer rotates relative to the core layer and breaks, so that the two are separated from each other, thereby completing the wire stripping.

[0071] It is easy to understand that the support 310 can be constructed as any suitable structure, and the first driving unit 340 can be any suitable existing device.

[0072] Alternatively, if Figure 5 As shown, the separation unit 320 includes a separation cone 321 and a separation thorn 332. The separation cone 321 is constructed as a hollow structure and has two opposite ends. The large end of the separation cone 321 is connected to the first drive unit 340, and the small end of the separation cone 321 is constructed as a core layer entrance connected to the hollow structure. The hollow structure is constructed as a temporary placement hole for the core layer. The outer surface of the separation cone 321 is constructed as an outer cladding separation surface. Accordingly, the first drive unit 340 uses a ring drive, and a plurality of separation thorns 332 are provided and evenly distributed on the core layer entrance.

[0073] Based on the above design, when the wire moves to the core layer entrance, the separation thorn 332 penetrates the gap between the outer layer and the core layer. When the wire feeding module 100 continues to feed, the outer layer and the core layer will be separated by the separation cone 321, and the core layer enters the core layer temporary placement hole. The outer layer moves along the outer layer separation surface from the small end of the separation cone 321 to the large end of the separation cone 321, which also gradually increases the gap between the outer layer and the core layer. At the same time, during the feeding process, the outer layer bends relative to the core layer, which also helps to reduce the difficulty of breaking the outer layer.

[0074] It is easy to understand that the inner diameter of the core layer entrance is slightly larger than the outer diameter of the core layer, ensuring that the separation thorn 332 can penetrate the gap between the outer cladding layer and the core layer. Further, the separation cone 321 is provided with different specifications, and the worker selects the separation cone 321 of the appropriate specification according to the size of the wire, ensuring that the separation unit 320 can separate the outer cladding layer and the core layer without damaging the core layer.

[0075] Accordingly, in order to avoid blocking the core layer entering the core layer temporary placement hole and to provide better power, the first drive unit 340 uses a ring drive. The separation thorn 332 can be configured in any suitable shape, and the present invention does not impose any limitation on this.

[0076] Alternatively, if Figure 5 As shown, the stripping unit 330 includes a plurality of blades evenly distributed on the outer cladding separation surface. Based on the above design, when the wire is fed, the blades are used to separate the wire bundles that make up the outer cladding, so that the wire bundles are relatively dispersed to avoid the accumulation of wire bundles. When the first driving unit 340 is started, the blades rotate with the separation cone 321, and the blades drive the wire bundles to rotate, so that the outer cladding breaks, and the wire bundles are separated from the core layer under the action of gravity, thereby achieving stripping.

[0077] It is easy to understand that the number of blades includes but is not limited to Figure 5 Five are shown, and those skilled in the art can appropriately increase or decrease the number of blades as needed.

[0078] In a possible implementation, the wire cutting module 200 includes a linear module 210 and a wire cutting pliers 220, and the wire cutting pliers 220 are slidably arranged on the linear module 210 and used to cut the outer sheath of the wire. Based on the above design, the wire cutting pliers 220 reciprocate along the linear module 210 to adjust the relative position of the wire and the wire cutting pliers 220, and combined with the feeding of the wire feeding module 100, the length of the cut portion of the wire is controlled.

[0079] Alternatively, if Figure 6 As shown, the wire cutter 220 includes a housing 221, a first blade 222, a second blade 223, a second driving unit 224 and an identification unit 225;

[0080] The housing 221 is slidably disposed on the linear module 210, and a shearing hole is disposed on the housing 221. Accordingly, the first blade 222 and the second blade 223 are disposed on the housing 221 and are relatively disposed with the shearing hole as the center.

[0081] The second driving unit 224 is connected to at least one of the first blade 222 and the second blade 223 to make the first blade 222 and the second blade 223 move closer to or separate from each other. The identification unit 225 is disposed on the housing 221 and is used to identify the wire.

[0082] Based on the above design scheme, the first blade 222 and the second blade 223 are both provided with a concave blade groove. When the first blade 222 and the second blade 223 are brought close to each other, the two blade grooves are connected and form a cutting hole suitable for the wire. By controlling the inner diameter of the cutting hole, it is ensured that the core layer will not be damaged, and at least one layer of outer cladding remains after cutting off the outer cladding, thereby greatly reducing the thickness of the outer cladding outside the core layer.

[0083] The identification unit 225 is used to identify the wire. When the wire feeding module 100 feeds to the wire moving identification unit 225, the identification unit 225 identifies the wire and then grasps the position of the wire. The wire feeding module 100 continues to feed or the wire cutter 220 moves until the length of the wire passing through the shear hole meets the design required shear length, effectively grasping the position information of the wire and improving the precision and accuracy of the wire cutting.

[0084] It is easy to understand that the identification unit 225 includes but is not limited to an infrared sensor, and any other suitable identification device may also be selected, and the second driving unit 224 may be selected from any suitable existing device.

[0085] Furthermore, according to different types of wires being processed, technicians in this field select first blade 222 and second blade 223 of appropriate sizes to control the internal strength of the cutting hole to ensure that the core layer will not be damaged when the outer cladding is removed.

[0086] Alternatively, if Figure 6 As shown, one of the first blade 222 and the second blade 223 is constructed as a fixed blade fixed on the housing 221, and the other is constructed as a movable blade connected to the second driving unit 224 and slidably set on the housing 221. Accordingly, when the wire is passed through the shearing hole, the movable blade slides along the shearing hole and shears the wire.

[0087] Based on the above design scheme, one of the first blade 222 and the second blade 223 is a fixed blade and the other is a movable blade. Reducing the number of moving devices helps to reduce errors and avoid damaging the core layer. Reducing the number of moving devices helps to reduce the probability of failure.

[0088] In conjunction with the structure of the wire cutter 220, the wire cutting process is explained: the wire feeding module 100 conveys the wire to the shearing hole, and the position of the wire is determined by the identification unit 225; the wire feeding module 100 continues to feed or the wire cutter 220 moves, and the wire passes through the shearing hole. When the length of the wire passing through the shearing hole meets the cutting length required by the design, it means that the wire cutter 220 reaches the tangent position; the second driving unit 224 is started, and the movable knife in the first blade 222 and the second blade 223 moves along the shearing hole toward the fixed knife to form a cutting hole and cut off multiple outer layers; the second driving unit 224 then drives the movable knife to reset.

[0089] In a possible implementation, the wire feeding module 100 includes a base 110, a third driving unit 120, a clamping hand 130, a pulley 140, a fourth driving unit 150 and a guide rail 160;

[0090] The base 110 is provided with a third driving unit 120, and the third driving unit 120 has two opposite output ends. The clamping hands 130 are provided with two and are respectively connected to the output ends of the third driving unit 120. Accordingly, the two clamping hands 130 are arranged opposite to each other and are used to clamp the wire.

[0091] The pulley 140 and the fourth driving unit 150 are respectively arranged on the base 110 , the guide rail 160 is located outside the base 110 and parallel to the linear module 210 , the pulley 140 is slidably arranged on the guide rail 160 , and the fourth driving unit 150 is used to drive the base 110 to slide reciprocatingly along the guide rail 160 .

[0092] Based on the above design, the third drive unit 120 is used to drive the two clamping hands 130 to move closer to or away from each other. When the two clamping hands 130 move closer to each other, the two clamping hands 130 can be used to clamp the wire. The pulley 140, the fourth drive unit 150 and the guide rail 160 cooperate with each other to realize the feeding of the wire feeding module 100, thereby reciprocating the wire to complete the wire cutting and stripping operations.

[0093] It is easy to understand that the third driving unit 120 and the fourth driving unit 150 can be any suitable existing equipment respectively.

[0094] During operation, the two grippers 130 are separated from each other. After the worker passes the wire through the two grippers 130, the third driving unit 120 is started to make the two grippers 130 move closer to each other and clamp the wire. The fourth driving unit 150 is then started to feed the wire, and the wire cutting and stripping operations are completed in coordination with the movement of the wire cutting pliers 220 and the wire stripping module 300.

[0095] Alternatively, if Figure 2-Figure 4As shown, the guide rail 160 is provided with a rack 170 parallel to the guide rail 160, and the output end of the fourth drive unit 150 is connected to a transmission gear 180, and accordingly, the transmission gear 180 is meshed with the rack 170. Based on the above design scheme, the fourth drive unit 150 realizes power transmission through gear transmission, which has the advantages of high transmission efficiency, high transmission accuracy, stable transmission, compact structure, long service life, etc., especially high transmission accuracy, which helps to reduce the error of the sheared length of the wire and improve the shearing quality.

[0096] Preferably, if Figure 2-Figure 4 As shown, the automatic wire stripping device further comprises a workbench 400, on which the wire feeding module 100, the wire cutting module 200 and the wire stripping module 300 are all arranged, and through the workbench 400, the various components in the automatic wire stripping device are connected as a whole.

[0097] Embodiment 2:

[0098] This embodiment introduces an automatic wire stripping method based on the automatic wire stripping device on the basis of the embodiment 1. Specifically: Figure 2-Figure 11 As shown, an automatic wire stripping method based on the automatic wire stripping device comprises the following steps:

[0099] S100: device initialization;

[0100] S200: The wire is fed into the wire feeding module 100; the wire feeding module 100 is started and the wire is clamped by the clamping hand 130;

[0101] S300: The wire feeding module 100 feeds the wire until the wire cleaver 220 recognizes the wire; at least one of the wire feeding module 100 and the wire cleaver 220 moves until the wire cleaver 220 is located at the wire cutting position;

[0102] S400: The wire cutter 220 cuts the wire until a groove is left on the innermost outer sheath of the wire;

[0103] S500: The wire feeding module 100 feeds the wire until the outer layer and the core layer of the wire are separated by the wire stripping module 300;

[0104] S600: the stripping module 300 is started to separate the outer layer and the core layer of the wire by rotation;

[0105] S700: the wire stripping module 300 stops rotating, and the wire feeding module 100 and the wire cutting pliers 220 are reset respectively until the wire reaches the sampling position; the wire is removed;

[0106] In S400, the depth of the groove is not less than 1 / 3 of the thickness of the innermost outer cladding layer; if the wires are processed in batches, S800 is also included: S200-S700 are repeated until all the wires are processed.

[0107] It is easy to understand that before the automatic wire stripping method is implemented, the corresponding model of separation unit 320 should be selected according to information such as the specifications of the wire, the stripping length, the thickness of a single outer layer, etc., and motion instructions should be input to the automatic wire stripping device through any suitable existing control equipment to realize intelligent and automated operation.

[0108] S100 includes but is not limited to the wire feeding module 100 moving to the initial position, the two clamping hands 130 separating from each other, the wire cutting pliers 220 moving to the initial position, and the first blade 222 and the second blade 223 separating from each other.

[0109] For S200, the staff manually loads the wires and ensures that the length of the wires passing through the two clamps 130 is greater than the stripping length, and a sufficient length is reserved to avoid mutual obstruction between the components in the automatic stripping device. Conversely, after the stripping is completed, the staff removes the wires. Alternatively, any suitable existing equipment is set outside the wire feeding module 100 to realize automatic assembly and disassembly of the wires, further reducing manual participation.

[0110] For S300, the fourth driving unit 150 is started to realize the feeding of the wire feeding module 100. When the wire is identified by the identification unit 225, it means that the end of the wire moves to the wire cutter 220. At this time, the wire feeding module 100 and the wire cutter 220 are linked to each other so that the length of the wire passing through the wire cutter 220 is equal to the wire stripping length, and the wire cutter 220 reaches the wire cutting position to ensure the accuracy of the wire stripping length. Optionally, it is preferred that the wire feeding module 100 stops and the wire cutter 220 moves to the wire cutting position along the straight line module.

[0111] For S400, the second drive unit 224 is started to cut the wire, thereby cutting off most of the outer cladding, and a groove is also left on the remaining outer cladding to reduce the difficulty of separating the outer cladding from the core layer, making the wire stripping operation more convenient and protecting the core layer to the greatest extent to avoid damage to the core layer.

[0112] For S500, after the wire cutting is completed, the wire feeding module 100 is started and fed again to convey the wire to the wire stripping module 300. With the help of the structure of the separation cone 321, the remaining outer cladding and the core layer are separated from each other, and the wire stripping operation is prepared.

[0113] For S600, the first driving unit 340 is started, the separation cone 321 and the plurality of blades rotate, thereby driving the remaining outer cladding to rotate, the outer cladding is broken at the cutting groove, so that the two are separated from each other, and the wire stripping is completed.

[0114] For S700, the device is reset, the stripped wire is removed, and the processing is completed.

[0115] If the wires are processed in batches, S800 is also included: S200-S700 are repeated until all the wires are processed.

[0116] Furthermore, the depth of the groove is not less than 1 / 3 of the thickness of the innermost outer cladding layer. Based on this, it is ensured that the core layer will not be damaged. If necessary, if the wire cutter 220 has sufficient accuracy, the depth of the groove can also be increased to reduce the difficulty of stripping the outer cladding layer at the wire stripping module 300.

It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
