Description

Technical Field

[0001] The invention relates to the technical field of electrical components, and in particular to an automatic laser wire stripping and twisting device. Background Art

[0002] Cold stripping and hot stripping are two common wire stripping methods in the wire processing process. Cold stripping mainly uses tools such as wire strippers and blades to cut the insulation material of the wire, but this method is easy to damage the metal core of the wire. Hot stripping mainly uses hot stripping, electric heating tweezers or lasers to heat and fuse the insulation layer of the wire, which has the advantage of not damaging the wire core. In the production and manufacturing of high-reliability and high-quality products, most wire stripping processes use hot stripping processes.

[0003] Existing heat stripping process equipment generally targets rolled wires, cuts the rolled wires into wire segments of required lengths, and then uses a heating device to strip, twist and tin the wires at both ends. However, this type of equipment cannot be used for single wires or wires with one end connected to a product.

[0004] In the production process of electronic products, a large number of wires are needed to connect the various modules inside the product, so in the electrical installation process of the product, there is generally an operation to handle the ends of individual wires. The existing process methods generally use manual operations such as hot wire stripping and electric heating tweezers to complete the processing of wire stripping, wire twisting and tinning, which is not only inefficient, but also high-temperature operation may endanger the health of workers.

[0005] Based on this, it is necessary to provide a wire stripping and twisting machine with stable wire stripping quality and high efficiency for the traditional wire stripping and twisting process. Summary of the invention

DETAILED DESCRIPTION

[0055] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0056] Example 1

[0057] like Figures 1 to 11As shown, an automatic laser wire stripping and twisting device includes a box mechanism 1, a laser wire stripping device 2, and a peeling and twisting device 3. The laser wire stripping device 2 includes left and right laser generating devices, a vacuum smoke extraction tube 29, front and rear protective covers 27, and a heat dissipation cover mechanism 28. The left and right laser generating devices include left and right laser generators 21, 22, left and right galvanometers 23, 24, and a laser generator fixing mechanism 26. The front and rear protective covers 27 and the heat dissipation cover mechanism 28 wrap the left and right laser generating devices to prevent laser injury and effectively dissipate heat. The peeling and twisting device 3 includes a rotating twisting mechanism 31, a peeling mechanism 32, a fixed wire mechanism 33 and a wire skin collecting device 34. The rotating twisting mechanism 31 includes a cable clamp mechanism and a first drive mechanism and its fixed tooling. The peeling mechanism 32 includes a second drive mechanism and its fixed tooling. The fixed wire mechanism 33 includes a cable guide block 331, a wire clamping mechanism 332, and a photoelectric sensor system 333. The wire skin collecting device 34 includes an air blowing mechanism 341 and a wire skin waste collection mechanism, which can collect wire skins to ensure a clean workbench and safe production. The laser stripping device 2 and the peeling and twisting device 3 are both above the box structure 1.

[0058] The automatic laser wire stripping and twisting device can strip and twist the wire 4 with a housing and other components.

[0059] The box mechanism 1 includes a laser generator control system, a galvanometer control system, a laser control card, a rotary wire twisting and peeling control system, and a fixing mechanism.

[0060] like Fig.10 As shown, the cable 4 to be processed includes a plurality of core wires 41 and a conductor insulation 42 connected to the outside of the plurality of core wires 41, and a laser stripping position 43 is provided on the conductor insulation 42;

[0061] like Figures 1 to 5 As shown, the laser wire stripping device 2 includes left and right laser generating devices 21, 22 and their fixing mechanisms. The power of the laser generating devices 21, 22 is adjustable from 5 to 30W, the working time of this embodiment is about 6s / wire, the applicable cable diameter range is: 0.1mm to 3mm, and the cable stripping length range is: 5mm to 18mm adjustable.

[0062] The laser generators 21 and 22 can emit laser beams, and the laser galvanometers 23 and 24 deflect the laser beams to form laser cutting lines. The heat energy of the laser cutting lines melts the laser skin.

[0063] The smoke purifier 29 of the laser wire stripping device 2 includes a vacuum smoke extraction tube, which can absorb dust generated by laser wire stripping to prevent smoke and dust from accumulating and affecting product quality and damaging equipment parts.

[0064] The protective device required by the laser wire stripping device 2 includes front and rear protective covers 27 and a heat dissipation cover plate 28 .

[0065] The rotating thread twisting mechanism 31 and the peeling mechanism 32 include motors, and the motor speed is adjustable.

[0066] like Figure 6 As shown, the peeling and twisting device 3 includes a rotating wire twisting mechanism 31, a peeling mechanism 32, a fixed wire mechanism 33 and a wire skin collecting device 34. The main function of the fixed wire mechanism 33 is that after the wire passes through the cable guide block, the cable clamp 311 clamps the product wire 4 to move the required distance, and the wire clamping mechanism 332 clamps the wire 4 near the outlet of the cable guide block 331 to prevent the wire 4 from moving again, affecting the total length accuracy of the laser stripping. When the wire 4 is clamped by the wire clamping mechanism 332, after the laser generator 21 and 22 cuts the wire skin on both sides of the wire 4, the rotating motor 319 drives the cable clamp 311 to rotate, and uses the clamping force and the friction force of the wire skin to tighten the wire core 41, which is the function of the rotating wire twisting mechanism. At the same time, the entire rotating mechanism 31 is driven to move backward, so that the wire clamp 3321 not only rotates to twist the wire core 41 but also moves backward to peel the wire skin 42, which is the function of the peeling mechanism. Air is blown through the pipe 341 in the wire sheath collecting device 34 to blow the stripped wire sheath into the wire sheath collecting bag below.

[0067] like Figures 10-11 As shown, the wire fixing mechanism 33 includes a cable guide block 331, a wire clamping mechanism 332 and a photoelectric sensor system 333. When the cable 4 passes through the cable guide block mechanism 331, the opposing light curtain sensor 333 at the end of the cable guide block mechanism 331 will sense it, and send a signal to control the cable clamp 311 to clamp the cable 4. Then, after the cable clamp 311 drives the wire 4 to move a proper distance, the wire clamp 3321 clamps the wire 4 to prevent it from moving, and then starts the next control action, including laser stripping, rotating wire twisting, peeling and other actions.

[0068] The left and right opposing light curtain sensors required by the photoelectric sensing system 333 can sense the wires, send out signals, close the cylinder, and control the cable clamp 311 to clamp the wire 4.

[0069] The cable guide block mechanism 331 includes a hollow cylinder with a diameter of about 0.5 mm and a length of 10 mm, which can ensure that the cable passes through the cable guide block mechanism horizontally. The function of the cable guide block 331 is to guide cables of different diameters into the interior of the device through the cable guide hole, so that the length of the wire 4 detected by the through-beam light curtain sensor 333 is more accurate, and the large difference in the cable cutting length caused by the bending of the wire 4 is reduced.

[0070] The wire clamping mechanism 332 includes a wire clamp 3321 and a fixed clamp cylinder 3322. After receiving the signal from the sensor 333, the wire clamp 3321 is controlled to clamp the wire 4 to prevent the wire from moving. The fixed clamp cylinder 3322 is a pneumatic drive unit, which drives the solenoid valve to operate under the host computer control system, allowing the cylinder to open and close, thereby clamping and loosening the wire 4.

[0071] like Figures 7-8 As shown, the rotary wire twisting mechanism 31 includes a cable clamp 311, a cable clamp push plate 312, a cable clamp base 313, a spring 314, a spring plate, a spring cover 315, a screw 316, a rotating rod 317, a slide cylinder 318, a first driving mechanism 319, a spring plate 31a, a sensor contact piece 31b, a position sensor 31c, and a fixing tool thereon.

[0072] The cable 311 clamps the cable 4 by the pressure of the spring 314, and the pressure of the spring 314 can be adjusted by adjusting the screw 316. The upper and lower springs 314 are installed on the upper and lower sides of the cable clamp 311, respectively located in the upper and lower slots of the cable clamp base 313. The cable clamp 311 moves up and down in the guide track of the cable clamp base 313 to clamp and release.

[0073] The cable clamp 311 includes a first cable clamp 3111 and a second cable clamp 3112 which are symmetrically arranged up and down.

[0074] The cable clamp push plate 312 is used to open the cable clamp 311 , and the slide cylinder 318 extends forward to drive the cable clamp push plate 312 to move forward to open the cable clamp 311 .

[0075] The first driving mechanism 319 includes a motor.

[0076] After the cable clamping jaws 311 clamp the cable 4 , the rotating wire twisting mechanism 31 controls the motor 319 to rotate and drive the clamping jaws 311 to rotate, and the speed is adjustable, so that the multiple core wires 41 are twisted together.

[0077] like Fig. 9 As shown, the peeling mechanism 32 includes a second driving mechanism 321, a coupling 322, a ball screw 323, a ball screw nut seat 324, a linear guide rail 325, a front position sensor 326, a rear position sensor 327, a sensor contact 328, a screw mechanism and a fixing tool thereon. The ball screw 323 and the linear guide rail 325 form a linear motion unit, which can drive the rotating wire core twisting mechanism 31 to move forward and backward, and can also move the required stripping length after the wire clamp 3321 clamps the cable 4 to perform laser stripping. Position sensors 326 and 327 can be used to determine the feeding position.

[0078] The ball screw nut seat 324 is provided with the overall structure of the rotating wire twisting mechanism 31 to drive the structure 31 to move forward and backward.

[0079] Position sensors 326, 327 and contact piece 328 are used to determine the feeding position. The rear position sensor 327 is the origin position. Every time the device is started, the feeding motor needs to return to the origin position. The front position sensor 326 is the limit position to ensure that the motion unit does not exceed the front limit position.

[0080] The second driving mechanism 321 includes a motor. The motor is a common stepping motor, which performs corresponding stepping motion under the motion control system of the host computer, and the motor 321 and the ball screw 323 are connected through the coupling 322 to drive the ball screw 323 to rotate, thereby driving the upper rotating wire twisting mechanism 31 to move.

[0081] The peeling mechanism 32 drives the rotating wire twisting mechanism 31 to retreat when the rotating wire twisting mechanism 31 is running. The retreat speed and distance are adjustable. The rotating wire twisting mechanism 31 retreats, driving the clamping claw 3321 to retreat, and driving the wire skin peeled off by the laser to retreat, thereby causing the wire skin to fall off.

[0082] The wire skin collecting device 34 includes a wire skin blowing nozzle 34 for blowing off the wire skin 3321 on the clamping jaws to prevent the residual wire skin on the clamping jaws 3321 from affecting the next wire clamping.

[0083] The working principle of this technical solution is as follows: when the wire 4 passes through the cable guide block 331, the beam-type light curtain sensor 333 receives a signal, and then controls the cable clamp 311 to clamp the wire 4. According to the set parameters, the peeling mechanism 32, i.e., the second driving mechanism 321, drives the clamped wire 4 to move the required distance, and then the wire clamp 3321 of the wire clamping mechanism 332 clamps the wire 4, and the laser generators 21 and 22 emit lasers to cut the wire skin. At the same time, the smoke purifier 29 starts to work and absorbs smoke. After laser peeling, the first driving mechanism 319 controls the rotation of the clamping jaws 311, thereby driving the wire 4 to rotate. At the same time, the second driving mechanism 321 drives the first driving mechanism 319 to retreat to the set distance, and the twisting and peeling of the wire 4 is completed. The cable clamp 311 opens, and the wire skin blowing nozzle 341 blows air, and the wire skin falls into the wire skin storage bag.

[0084] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
