Description

TECHNICAL FIELD

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

[0002] Cold stripping and hot stripping are two common wire stripping methods in wire processing technology. Cold stripping mainly cuts the insulating layer of the wire through wire strippers, blades and other tools, but this method is easy to damage the metal wire core. Hot stripping mainly melts the insulating layer of the wire through hot stripping, electric heating tweezers or laser, and has the advantage of not damaging the wire core. In the production of high-reliability and high-quality products, hot stripping process is mostly used in wire stripping.

[0003] The existing hot stripping processing equipment generally processes coiled wires, cuts the coiled wires into wire segments of the required length, and then uses a heating device to strip, twist and tin the two ends of the wire, but it cannot be used for single wires or wires connected to products.

[0004] In the production process of electronic products, a large number of wires are needed to connect various modules inside the product, so in the product electrical assembly process, there is generally an operation to process the end of the single wire. The existing process method generally uses hot stripping, electric heating tweezers and other manual operations to complete the stripping, twisting and tinning process, which not only has low efficiency, but also high-temperature operation may harm the health of workers.

[0005] Therefore, it is necessary to provide a wire stripping and twisting all-in-one machine with stable stripping quality and high efficiency based on the traditional wire stripping and twisting process. SUMMARY

DETAILED DESCRIPTION

[0055] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments.

[0056] Embodiment 1

The left and right laser generating devices include left and right laser generators 21, 22, left and right galvanometer mirrors 23, 24, and a laser generator fixing mechanism 26. The front and rear protective covers 27 and the heat dissipation cover plate mechanism 28 wrap the left and right laser generating devices to prevent laser injuries and effectively dissipate heat. The peeling and twisting device 3 includes a rotating and twisting mechanism 31, a peeling mechanism 32, a fixed wire guide mechanism 33, and a wire skin collecting device 34. The rotating and twisting mechanism 31 includes a cable clamp mechanism, a first driving mechanism, and a fixing tool. The peeling mechanism 32 includes a second driving mechanism and a fixing tool. The fixed wire guide mechanism 33 includes a cable guide block 331, a wire clamping mechanism 332, and an optical sensor system 333. The wire skin collecting device 34 includes a blowing mechanism 341 and a wire skin waste collecting mechanism, which can collect wire skins and ensure a clean workbench and safe production. The laser wire stripping device 2 and the peeling and twisting device 3 are above the box mechanism 1.

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

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

[0060] As shown in Figure 10 The cable to be processed 4 includes a plurality of core wires 41 and a wire insulation skin 42 connected to the outside of the plurality of core wires 41. A laser wire stripping position 43 is provided on the wire insulation skin 42.

[0061] As shown in Figures 1-5 The laser wire stripping device 2 includes left and right laser generating devices 21, 22, and a fixing mechanism. The power of the laser generating devices 21, 22 is adjustable and ranges from 5 W to 30 W. The working time of the embodiment is about 6 s per root. The cable diameter range is 0.1 mm to 3 mm. The cable off-head length range is adjustable and ranges from 5 mm to 18 mm.

[0062] The laser generators 21, 22 can emit laser beams. The laser beams are deflected by the laser galvanometer mirrors 23, 24 to form a laser cutting line. The thermal energy of the laser cutting line melts the laser skin.

[0063] The smoke purifier 29 of the laser wire stripping device 2 includes a vacuum smoke extraction pipe, which can suck up dust generated by laser wire stripping to avoid the accumulation of smoke dust, which affects product quality and damages equipment parts.

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

[0065] The rotating twisting mechanism 31 and the peeling mechanism 32 include motors with adjustable speed.

[0066] like Figure 6 As shown, the wire stripping and twisting device 3 includes a rotating twisting mechanism 31, a wire stripping mechanism 32, a wire fixing mechanism 33, and a wire sheath collecting device 34. The main function of the wire fixing mechanism 33 is that after the wire passes through the cable guide block, the cable clamp 311 holds the wire 4 for the required distance, and the wire holding mechanism 332 holds the wire 4 near the exit of the cable guide block 331 to prevent the wire 4 from moving again and affecting the accuracy of the laser stripping length calculation. When the wire 4 is held by the wire holding mechanism 332, the laser generators 21 and 22 cut the wire sheath on both sides of the wire 4, and the rotating motor 319 drives the cable clamp 311 to rotate. Using the clamping force and the friction of the wire sheath, the wire core 41 is tightened; this is the function of the rotating twisting mechanism. Simultaneously, the entire rotating mechanism 31 is moved backward, causing the wire clamp 3321 to both rotate to twist the wire core 41 and strip the wire sheath 42 backward; this is the function of the wire stripping mechanism. Air is blown through the pipe 341 in the wire sheath collection device 34 to blow off the stripped wire sheath into the wire sheath collection 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 sensing system 333. When the cable 4 passes through the cable guide block mechanism 331, the through-beam 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, the cable clamp 311 drives the wire 4 to move an appropriate distance, and the wire clamp 3321 clamps the wire 4 to prevent it from moving, and then the next control action begins, including laser stripping, rotating twisting, and stripping.

[0068] The left and right through-beam light curtain sensors required by the photoelectric sensing system 333 can sense the wires, send signals to 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 approximately 0.5 mm and a length of 10 mm, which ensures that the cable passes horizontally through the cable guide block mechanism. The function of the cable guide block 331 is to guide cables of different diameters into the equipment 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 cable cutting length caused by the bending of the wire 4 is reduced.

[0070] Wire clamping mechanism 332 includes wire clamp 3321 and fixed clamp air cylinder 3322, after receiving the signal given by sensor 333, control wire clamp 3321 to clamp wire 4 to prevent wire movement. Fixed clamp air cylinder 3322 is a pneumatic drive unit, under the control of the host computer system, drive electromagnetic valve to act, let the cylinder do open and close action, in this way to clamp and relax wire 4.

[0071] As shown in Figures 7-8 Rotary wire twisting mechanism 31 includes cable clamp 311, cable clamp push plate 312, cable clamp base 313, spring 314, spring plate, spring cover 315, screw 316, rotary rod 317, sliding table air cylinder 318, first drive mechanism 319, spring plate 31a, inductor contact 31b, position sensor 31c, and the fixed tool thereon.

[0072] Cable 311 is clamped by the pressure of spring 314, the pressure of spring 314 can be adjusted by adjusting screw 316. The upper and lower springs 314 are installed on the upper and lower sides of cable clamp 311, respectively located in the upper and lower groove holes of cable clamp base 313. Cable clamp 311 moves up and down in the guide rail of cable clamp base 313 to make clamping and loosening action.

[0073] Cable clamp 311 includes first cable clamp 3111 and second cable clamp 3112 arranged symmetrically up and down.

[0074] Cable clamp push plate 312 is used to open cable clamp 311, sliding table air cylinder 318 extends forward to drive cable clamp push plate 312 to move forward to open cable clamp 311.

[0075] First drive mechanism 319 includes a motor.

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

[0077] As shown in Figure 9 Peeling mechanism 32 includes second drive mechanism 321, coupling 322, ball screw 323, ball screw nut seat 324, linear slide rail 325, front end position sensor 326, rear end position sensor 327, inductor contact 328, screw mechanism and the fixed tool thereon. Ball screw 323 and linear slide rail 325 constitute a linear motion unit, which can drive rotary wire twisting core mechanism 31 to move forward and backward, and can move the required stripping length after wire clamp 3321 clamps cable 4 to perform laser stripping. Position sensors 326 and 327 can be used to determine the position of feeding.

[0078] The whole structure of the rotating wire twisting mechanism 31 is installed on the ball screw nut base 324, and drives the structure 31 to move forward and backward.

[0079] The position sensors 326, 327 and the touch piece 328 are used to determine the position of the feed, and the rear end position sensor 327 is the original position, and the feed motor needs to return to the original position each time the device is started. The front end position sensor 326 is the limit position, which ensures that the movement unit does not exceed the front limit position.

[0080] The second driving mechanism 321 includes a motor. The motor is a common step motor, which makes corresponding step movement under the motion control system of the upper computer, and is connected with the ball screw 323 through the shaft coupling 322, drives the ball screw 323 to rotate, and then drives the rotating wire twisting mechanism 31 above to move.

[0081] The peeling mechanism 32 drives the rotating wire twisting mechanism 31 to retreat at the same time when the rotating wire twisting mechanism 31 operates, and the retreat speed and distance are adjustable. The rotating wire twisting mechanism 31 retreats, drives the clamp jaw 3321 to retreat, and drives the laser stripped wire skin to retreat, so that the wire skin falls off.

[0082] The wire skin collecting device 34 includes a wire skin blowing nozzle 34, which blows off the wire skin on the clamp jaw 3321, so as to avoid the influence of the residual wire skin on the clamp jaw 3321 on the next wire clamping.

[0083] The working principle of the technical solution is as follows: when the wire 4 passes through the cable guide block 331, the light curtain sensor 333 receives a signal, and then the cable clamp 311 clamps 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 mechanism 332 clamps the wire 4 with the wire clamp 3321. The laser generator 21, 22 emits laser to cut the wire skin, and the smoke purifier 29 starts to work to absorb the smoke. After the laser peeling, the first driving mechanism 319 controls the clamp jaw 311 to rotate, 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 completes the wire twisting and peeling of the wire 4. The cable clamp 311 is opened, the wire skin blowing nozzle 341 blows air, and the wire skin falls into the wire skin storage bag.

[0084] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
