Description

Technical Field

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

[0002] The twisted wire pin connector relies on its unique structural design to provide stable electrical performance under extreme conditions. The core of the twist pin (twisted wire pin) lies in its unique structure, which not only ensures the reliability and durability of the connector, but also allows it to be used in precision instruments and equipment in various harsh environments. The twist pin is made of two layers of copper alloy wires with different numbers of inner and outer layers twisted together. This design gives the pin excellent elasticity and toughness. The pin has a drum-shaped protrusion on one or both ends. When the pin enters the socket, these drum-shaped parts will deform due to the interference fit to provide the necessary contact pressure. When the pin is pressed into the socket, the deformation of the drum-shaped part causes the pin to form multiple contact points with the socket wall, increasing the reliability of the electrical connection. The two ends of the twist pin are fixed together by welding or other methods to ensure that they will not loosen during use. These characteristics make the twisted wire pin connector very suitable for applications that require high reliability and durability, such as aerospace, military equipment, navigation equipment and other demanding industrial fields. These environments are often accompanied by challenges such as vibration, shock and temperature changes, and the twist pin is designed to meet these challenges.

[0003] At present, in the production process of twisted wire pin connectors, it is necessary to remove a certain length of the insulation layer of the wire head in order to carry out the subsequent crimping process. The traditional head stripping method relies on wire strippers or blade stripping machines, which is not suitable for mass production and has low processing efficiency. A patent for laser wire stripping equipment with publication number CN213497203U introduces a new solution, which includes a frame, a laser emitting assembly, a drive assembly and a fixture. The laser emitting assembly is mounted on the frame and has a first emitting part and a second emitting part, and the two emitting parts emit lasers in opposite directions. The drive assembly is also mounted on the frame, and the fixture is mounted on the drive assembly for clamping the wire. The drive assembly is responsible for driving the fixture to move between the first emitting part and the second emitting part, so that the laser emitted by the emitting part can act on the wire.

[0004] Although the above technology improves the efficiency of wire stripping through the laser emission component, there are some problems in actual application when only relying on the laser emission component to cut the wire. In particular, the precision requirements for parameters such as laser power, frequency and pulse width are very high. When processing very thin stranded wire pin connector wires, it is easy to cause internal damage to the wire or the incision is too small, which directly affects the efficiency of stripping. Therefore, it is necessary to propose a cutting device and method specifically for wire stripping to solve the above problems and ensure the efficiency and safety of the stripping process.

[0019] In order to solve the technical problems in the prior art that the precision requirements for parameters such as laser power, frequency and pulse width are very high, and when processing very thin stranded wire pin connector wires, it is easy to cause internal damage to the wires or the incision is too small, the present invention provides a wire stripping and cutting device, which can ensure that the incision size meets the requirements without causing internal damage to the wires.

[0020] It should be noted that the wire stripping and cutting device described in the present invention is used for but not limited to wire stripping and cutting, etc. For the convenience of explanation, in the present invention, only an example of a wire stripping and cutting device applied to a wire stripping and cutting device is used for explanation. The principle of a wire stripping and cutting device applied to other types of equipment is essentially the same as the principle applied to a wire stripping and cutting device, which will not be repeated here.

[0021] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 It is a structural schematic diagram of a wire stripping and cutting device in one embodiment of the present invention, wherein the wire stripping and cutting device comprises a frame 1, a laser emitting mechanism 5, a wire straightening mechanism 3, a clamping claw traction mechanism 4, an opening and cutting mechanism 6 and a wire pulling mechanism 7.

[0022] In this embodiment, the frame 1 is used to support the device. The laser emitting mechanism 5 includes two laser transmitters 502 with emitting ends arranged opposite to each other, which are used to emit laser to cut the wire when the wire passes through the two. The incoming wire straightening mechanism 3 is located in front of the laser emitting mechanism 5, and is used to straighten the wire when it passes through. The clamping claw traction mechanism 4 is located between the incoming wire straightening mechanism 3 and the laser emitting mechanism 5, and is used to clamp the end of the wire passing through the incoming wire straightening mechanism 3, and pull the end of the wire to pass through between the two laser transmitters 502. The opening and cutting mechanism 6 is located behind the laser emitting mechanism 5, and is used to expand the incision opened by the laser transmitter 502 and cut the wire. The wire pulling mechanism 7 is located behind the opening and cutting mechanism 6, and can be side by side with the opening and cutting mechanism 6, and is used to pull the wire after the incision is expanded. By sequentially designing the incoming wire straightening mechanism 3, the clamping claw traction mechanism 4, the laser emitting mechanism 5, the opening and cutting mechanism 6 and the wire pulling mechanism 7 on the frame 1, the clamping claw traction mechanism 4 can be used to pull the front end of the wire to between the two laser transmitters 502 of the laser emitting mechanism 5 to complete the laser cutting work, and before that, the incoming wire straightening mechanism 3 can be used to straighten the guide, and then the opening and cutting mechanism 6 can be used to open the incision, so that through the secondary expansion of the opening and cutting mechanism 6, the cutting accuracy requirements for the laser transmitter 502 can be reduced to avoid damaging the internal structure of the wire. At the same time, it can be ensured that the size of the opening meets the requirements, and finally the guide is pulled out by the wire pulling mechanism 7, and the opening and cutting mechanism 6 is used to cut the wire.

[0023] In one embodiment, see Fig.14, also includes a guide frame 2, which is placed on the side of the frame 1, and includes a placement frame 201, a guide positioning frame 202 and a guide positioning hole 203. The number of the guide positioning frames 202 is multiple and is mounted on the two side walls of the placement frame 201. The number of the guide positioning holes 203 is multiple and is equidistantly arranged on the guide positioning frame 202.

[0024] In this embodiment, the placement frame 201 can place six wire bobbins at the same time, and the six wire bobbins are placed in two rows therein. There are two guide positioning frames 202, corresponding to the two rows of wire bobbins respectively. Three guide positioning holes 203 are provided on each guide positioning frame 202, and the three guide positioning holes 203 correspond to a single wire bobbin in each row respectively. The wires on the wire bobbins pass through the corresponding guide positioning holes 203 and enter the wire straightening mechanism 3, thereby avoiding mutual entanglement between the guides.

[0025] Furthermore, it also includes a receiving groove 8, which is arranged on the frame 1 and is located directly below the wire pulling mechanism 7. The receiving groove 8 can be used to receive the wire that has been stripped and cut.

[0026] In one embodiment, see Figure 3 and Figure 4 The incoming line straightening mechanism 3 includes a supporting structure 31 and a straightening mechanism, and the straightening mechanism is arranged on one side of the top of the supporting structure 31.

[0027] Furthermore, the supporting structure 31 includes a vertical plate 310, a support plate 311 and an L-shaped top support member 312. The vertical plate 310 is arranged on the frame 1, and the support plate 311 is arranged on the side of the vertical plate 310 and connected to the top of the frame 1. The support of the vertical plate 310 can be improved by the support plate 311. The L-shaped top support member 312 is arranged on one side of the top of the vertical plate 310, and the L-shaped top support member 312 is used to support the straightening mechanism.

[0028] Furthermore, the straightening mechanism includes a fixed straightening portion 33 and an adjustable straightening portion 34 .

[0029] Furthermore, the fixed straightening portion 33 includes a fixed seat 331 and a fixed straightening wheel 332. The fixed seat 331 is arranged on the top of the L-shaped top support member 312. The number of the fixed straightening wheels 332 is multiple and is equidistantly and rotatably arranged on the front side of the fixed seat 331. In this embodiment, the number of the fixed straightening wheels 332 is five, and the guide passes through the five fixed straightening wheels 332 in sequence.

[0030] Furthermore, the adjustment and straightening part 34 includes a lifting adjustment component and a lifting and straightening component, and the lifting adjustment component is used to control the lifting and lowering of the lifting and straightening component.

[0031] The lifting and lowering adjustment assembly includes a support plate 340, an L-shaped fixing frame 341, a rotating handle 342, an arc-shaped push-pull portion 343 and a push-pull rod 344. The support plate 340 is arranged on the back side of the fixing seat 331, the L-shaped fixing frame 341 is arranged on the front side of the top of the support plate 340, and the rotating handle 342 is rotatably arranged on the front side of the L-shaped fixing frame 341. One end of the arc-shaped push-pull portion 343 is hinged to the rotation point of the rotating handle 342, and the other end is hinged to the top of the push-pull rod 344. The push-pull rod 344 can telescopically penetrate the L-shaped fixing frame 341, so that the arc-shaped push-pull portion 343 can be used to push and pull the push-pull rod 344 in the L-shaped fixing frame 341 by rotating the rotating handle 342, so that the height can be switched. It should be noted that the position fixation of the rotating handle 342 is achieved by friction.

[0032] Furthermore, the lifting and straightening assembly includes a lifting limit rod 345, a lifting seat 346 and a lifting and straightening wheel 347. The number of the lifting limit rods 345 is two, and they are symmetrically arranged on the top of the fixed seat 331. The lifting seat 346 can be lifted and lowered and is fitted on the outside of the two lifting limit rods 345, and the top is connected to the bottom end of the push-pull rod 344, so that its lifting and lowering can be controlled by lifting and lowering the push-pull rod 344. The number of the lifting and straightening wheels 347 is multiple, and they are rotatably arranged on the front side of the lifting seat 346. In this embodiment, the number of the lifting and straightening wheels 347 is four, and the lifting and straightening wheels 347 and the fixed straightening wheels 332 are staggered, and both are provided with wire grooves adapted to the wires, and the number of the wire grooves is adapted to the number of the wires, which is six.

[0033] Specifically, the working principle of the straightening mechanism is: first, the lifting and straightening assembly is raised to the highest point by turning the rotating handle 342 upwards, and the wire is pulled to pass through each fixed straightening wheel 332 of the fixed straightening part 33 and embedded in the corresponding wire groove. Then, the rotating handle 342 is turned downwards to control the lifting and straightening assembly to descend until the wire groove of each lifting and straightening wheel 347 thereon contacts with the corresponding wire, thereby guiding it to pass between the lifting and straightening wheel 347 and the fixed straightening wheel 332 to realize the straightening work on it.

[0034] Furthermore, the inlet wire straightening mechanism 3 also includes an inlet wire limiting portion 32, which can limit the guide entering the straightening mechanism. The inlet wire limiting portion 32 includes an L-shaped mounting seat 320, a through groove 321, a threading plate 322 and a threading hole 323. The L-shaped mounting seat 320 is arranged on the other side of the top of the vertical plate 310, and the through groove 321 is arranged at the top center of the L-shaped mounting seat 320, and corresponds to the docking axis of the fixed straightening wheel 332 and the lifting straightening wheel 347, so as to facilitate the guide to enter the straightening mechanism from the through groove 321. The threading plate 322 is arranged on the side of the L-shaped mounting seat 320 by bolts. The number of the threading holes 323 is multiple, and is equidistantly arranged on the threading plate 322 and corresponds to the through groove 321. In this embodiment, the number of the threading holes 323 is six.

[0035] With such a design, the six wire threading holes 323 can be used to position and limit the six wires, which can effectively prevent them from coming out during straightening.

[0036] In one embodiment, see Figure 5 and Figure 6 The clamping claw traction mechanism 4 includes a first support frame 401, a Y-axis screw linear module 402, an X-axis screw linear module 403, and a clamping claw assembly. The first support frame 401 is arranged on the frame 1, the Y-axis screw linear module 402 is arranged on the top of the first support frame 401, and the X-axis screw linear module 403 is arranged on the slide of the Y-axis screw linear module 402.

[0037] Such a design allows the clamping jaw assembly to move in the X and Y axis directions to the left and right of the Y-axis lead screw linear module 402 and the X-axis lead screw linear module 403, so that the front end of the guide can be accurately sent between the two laser transmitters 502 to complete the laser cutting work.

[0038] Furthermore, the clamping jaw assembly includes a mounting frame 404, a traction clamping jaw 405 and a clamping cylinder 406. The mounting frame 404 is arranged on the slide table of the X-axis screw linear module 403. The number of the traction clamping jaws 405 is two, which are symmetrically arranged in the mounting frame 404. The opposite sides of the two traction clamping jaws 405 are provided with positioning grooves adapted to the wires. The clamping cylinder 406 is arranged on the top of the mounting frame 404, and its telescopic end passes through the mounting frame 404 and is connected to the traction clamping jaw 405 located above.

[0039] In this embodiment, the mounting frame 404 is a rectangular frame, and two traction claws 405 are located in the rectangular frame, wherein the lower traction claw 405 is mounted on the inner bottom wall of the rectangular frame, so that the upper traction claw 405 can be lifted and lowered in a small range by controlling the extension and retraction of the clamping cylinder 406, thereby completing the clamping and releasing effect of the guide. It should be noted that the slot height of the rectangular frame meets the requirements for lifting and lowering the traction claw 405. In addition, the positioning groove on the traction claw 405 is slightly smaller than the diameter of the wire, so that while tightening it, the positioning groove can play a limiting role when releasing it to avoid deviation.

[0040] In one embodiment, see Figure 7-Figure 9 The opening and cutting mechanism 6 includes a second support frame 601, a transverse screw linear module 602, a pneumatic parallel clamp 603, a transverse mounting block 604 and an opening and cutting tool 605. The second support frame 601 is arranged on the frame 1, the transverse screw linear module 602 is arranged on the top of the second support frame 601, the pneumatic parallel clamp 603 is arranged on the slide of the telescopic transverse screw linear module 602, the number of the transverse mounting blocks 604 is two, and they are relatively arranged on the two slides of the pneumatic parallel clamp 603, the number of the opening and cutting tools 605 is two, and the blades are relatively arranged in the mounting grooves of the two transverse mounting blocks 604; Furthermore, the blade of the opening and cutting tool 605 includes an opening section 6050 and a cutting section 6051. When the two opening and cutting tools 605 are closed, a gap is provided between the two opening sections 6050 for expanding the incision. The cutting section 6051 is used to cut the wire. In the present embodiment, the opening section 6050 is provided on the side close to the wire.

[0041] Specifically, the working principle of the expansion is: when the front end of the wire completes the upper and lower incisions through the two laser transmitters 502, and the incision is sent to be parallel to the cutting tool 605 through the clamping claw traction mechanism 4, the opening and the opening section 6050 of the cutting tool 605 are moved horizontally to the wire incision through the transverse screw linear module 602, and the two opposite opening sections 6050 are closed through the pneumatic parallel clamp 603, so as to expand the incision. After the expansion is completed, it is moved to the original position through the transverse screw linear module 602, which is convenient for the wire pulling mechanism 7 to perform the wire pulling work.

[0042] In addition, when cutting is required, the cutting section 6051 of the opening and cutting tool 605 is moved to the wire cutting position, and the specific principle is the same as above.

[0043] In one embodiment, see Figure 10-13The wire pulling mechanism 7 includes a linear guide rail 71, an extension support frame 72 and a clamping mechanism 73. The linear guide rail 71 is arranged on the frame 1. The specific length of the linear guide rail 71 is determined according to the cutting length of the wire, and the length of the receiving groove 8 is adapted thereto. The extension support frame 72 includes an extension frame 720 and a support platform 721. The tail end of the extension frame 720 is arranged on the slide of the linear guide rail 71, and the support platform 721 is horizontally arranged at the front end of the extension frame 720. The clamping mechanism 73 includes a first clamping component 730 and a second clamping component 731. The second clamping component 731 and the first clamping component 730 are arranged on the support platform 721 in a staggered manner front and back.

[0044] With such a design, the clamping mechanism 73 on the support platform 721 can be sent to be parallel to the opening and cutting mechanism 6 through the extension frame 720, so that the clamping mechanism 73 can clamp the guide. At the same time, by arranging the second clamping assembly 731 and the first clamping assembly 730 staggered front and back on the support platform 721, it is convenient to double clamp the front end of the guide to prevent it from being pulled apart or detached due to insufficient clamping length. Specifically, the second clamping assembly 731 at the rear of the clamping mechanism 73 is sent to the front end of the wire through the linear guide rail 71 and the extension support frame 72, and it is clamped by the second clamping assembly 731. Then, after the wire is pulled out backward to a certain distance, the guide is clamped for the second time by the first clamping assembly 730 in front.

[0045] Furthermore, the second clamping assembly 731 and the first clamping assembly 730 both include a pneumatic finger 7300, a clamping mounting seat 7301, a docking port 7302 and a clamping block 7303. The pneumatic finger 7300 is arranged on the support platform 721. The number of the clamping mounting seat 7301 is two, and they are respectively connected to the two clamping claws of the pneumatic finger 7300 through the docking port 7302 arranged on the back side thereof. The number of the clamping blocks 7303 is two, and they are relatively arranged on the two clamping mounting seats 7301, so that the two clamping blocks 7303 can be driven by the pneumatic finger 7300 to complete the clamping work of the guide.

[0046] Furthermore, the traction clamp 405 includes a clamp block 4050 and a pointed clamp mouth 4051. The pointed clamp mouth 4051 is arranged on the side of the clamp block 4050 close to the wire pulling mechanism 7. The clamping sides of the two pointed clamp mouths 4051 are flat, and the separated sides are pointed slopes. Its structure can effectively avoid unnecessary interference between the first clamping component 730 and the second clamping component 731 when the second clamping component 731 clamps the guide.

[0047] In one embodiment, see Fig.15The laser emitting mechanism 5 also includes two symmetrically arranged hand-cranked screw lifting mechanisms 502, and the two hand-cranked screw lifting mechanisms 502 are symmetrically arranged on the frame 1. The two laser transmitters 501 are respectively arranged on the lifting platforms of the two hand-cranked screw lifting mechanisms 502, so that the distance between the two laser transmitters 501 can be appropriately adjusted through the two hand-cranked screw lifting mechanisms 502.

[0048] The above embodiments are merely multiple possible implementations of the embodiments of the present application, and the embodiments of the present application are not limited thereto.

[0049] In a second aspect, the present invention provides a wire stripping and cutting method, which is applicable to a wire stripping and cutting device as described in any one of the above, and the method specifically comprises the following steps: S1. Manually pass the wire through the incoming wire straightening mechanism 3 and the clamp traction mechanism 4. The specific process is: after the wires of the six wire tubes in the placement frame 201 are passed through the corresponding guide positioning holes 203, they pass through the six threading holes 323 of the incoming wire limiting part 32, the fixed straightening part 33 and the adjustable straightening part 34 of the straightening mechanism and the two traction claws 405 of the clamp traction mechanism 4 in sequence.

[0050] S2. Clamp the wire with the clamping claw traction mechanism 4 and make the front end of the wire come out. The clamping cylinder 406 on the clamping claw traction mechanism 4 controls the upper traction clamping claw 405 to cooperate with the lower traction clamping claw 405 to clamp the wire.

[0051] S3, using the clamping claw traction mechanism 4 to clamp the wire and move it in the X and Y axes, so that the front end of the wire moves between the two laser transmitters 502, and the front end of the wire is laser cut by the two laser transmitters 502; S4, after the laser incision is completed, the clamping claw traction mechanism 4 clamps the wire and continues to move forward along the X-axis, and sends the wire incision to be parallel to the opening and cutting mechanism 6, and then moves the cutter of the opening and cutting mechanism 6 to the incision by lateral movement, and enlarges the incision, and then moves the cutter to the original position; S5, move the wire pulling mechanism 7 to the wire, clamp the front end of the wire, release the clamping of the clamping claw traction mechanism 4, use the wire pulling mechanism 7 to pull the wire backward for a certain distance, then perform double clamping, and then continue to pull the wire to a preset length; S6, move the cutter of the opening and cutting mechanism 6 to the wire by horizontal movement again, cut the wire, and finally release the wire pulling mechanism 7.

[0052] The present invention supports the entire structure through a frame 1, and the laser emitting mechanism 5 is composed of two laser transmitters 502 arranged opposite to each other, which are used to emit lasers to make cuts when the wire passes through them. The wire straightening mechanism 3 is located in front of the laser emitting mechanism 5 to ensure that the wire remains straight before entering the cutting area. The clamping claw traction mechanism 4 is responsible for clamping the straightened wire end and pulling it between the laser emitting mechanism 5. The opening and cutting mechanism 6 is located behind the laser emitting mechanism 5, which is used to expand the laser incision and finally cut the wire. The wire pulling mechanism 7 is used to pull the wire after the incision is expanded. In addition, the device also includes a guide frame 2, which includes a placement frame 201, a guide positioning frame 202 and a guide positioning hole 203, which is used to place multiple wire tubes and prevent the wires from being entangled with each other. The receiving groove 8 is set on the frame 1 to collect the wires after stripping and cutting. The wire-in straightening mechanism 3 is composed of a support structure 31 and a straightening mechanism, which is further divided into a fixed straightening part 33 and an adjustable straightening part 34. The height of the straightening wheel is adjusted by rotating the handle 342 to control the lifting and adjusting assembly, so as to achieve effective straightening of the wire. The wire-in limiting part 32 ensures that the wire is in the correct position when entering the straightening mechanism. The clamping claw traction mechanism 4 realizes the accurate feeding of the wire by moving in the X and Y axis directions. The traction clamping claw 405 and the clamping cylinder 406 in the clamping claw assembly ensure the stable clamping and release of the wire. The opening and cutting mechanism 6 uses the opening and cutting tool 605 that moves laterally to expand and cut the wire. The tool is divided into an opening section 6050 and a cutting section 6051 to ensure the accuracy and integrity of the incision. The wire pulling mechanism 7 realizes the smooth pulling out of the wire through the linear guide 71 and the extension support frame 72. The first clamping assembly 730 and the second clamping assembly 731 in the clamping mechanism 73 ensure the double clamping of the wire during the pulling out process to prevent the wire from breaking or falling off.

[0053] In summary, the wire stripping and cutting device not only improves the efficiency of stripping and cutting, but also minimizes the risk of damage to the wire through reasonable design and effective coordination of various parts. It is suitable for the stripping and cutting needs of various types of wires.

[0054] The present invention effectively solves the technical problems of very high precision requirements on parameters such as laser power, frequency and pulse width, or easily causing internal damage to the wire or too small incision when processing very thin stranded wire pin connector wires, by coordinating the laser emitting mechanism 5 with the opening and cutting mechanism 6. The present invention can effectively improve the stripping and cutting precision of the stranded wire pin connector wires.

[0055] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
