[0002] In the circuits used in electronic devices, different circuit boards and components need to be electrically connected through wires. Since the core wire of the wire is covered with insulating rubber, it is generally necessary to peel off a section of the rubber before welding, and tin the exposed core wire to ensure that the core wire is not loose during welding, and to ensure the welding quality between the wire and the electronic components.

[0003] In order to improve the efficiency of wire welding, the industry generally uses automatic wire stripping equipment to strip and tin the wires, and then sends the tinned wires to the welding station for welding. Since there may be many different specifications of wires to be welded on the same circuit board, or in order to distinguish the wires of different components, the core wires of the wires are covered with insulating rubbers of different colors. In the prior art, the wires provided by the automatic wire stripping equipment are fixed and cannot provide different wires according to different processes. If there is a need to weld different wires, it is necessary to use multiple wire stripping and feeding equipment to feed them separately, or use multiple automatic welding lines to weld different wires. The above methods require relatively high investment costs and require more space in the factory, which is very inconvenient.

[0004] Therefore, the prior art has defects and needs to be improved. Utility Model Content

[0020] During operation, the wire supply mechanism 1 inserts different wires into the sliding wire seat 23 of the wire distribution mechanism 2 in sequence according to the set regular distribution. When a certain type of wire or a certain type of wire combination needs to be selected for welding, the wire distribution drive mechanism 22 is started to drive the sliding wire seat 23 to move, so that the corresponding position of the sliding wire seat 23 with the corresponding wire inserted corresponds to the wire clamping position of the traction mechanism 4. The traction mechanism 4 moves to the side of the sliding wire seat 23, clamps the selected wire and moves in the direction of the stripping and cutting mechanism 3, and clamps and fixes the wire through the wire clamping mechanism 5, while releasing the traction mechanism 4. Then the outer rubber layer of the wire at the stripping position is cut off by the stripping and cutting mechanism 3, and the core wire of the wire is cut off at the cutting position, meeting the needs of stripping and cutting the wire.

[0021] In some embodiments, the line driving mechanism 22 uses a servo motor, the output end of the servo motor is connected to a screw transmission mechanism, and the output end of the screw transmission mechanism is connected to the sliding wire seat 23. The servo motor has the characteristics of fast response, high sensitivity, high precision, strong stability, etc., can quickly respond to control signals, and achieve very precise position control and motion control, meet the needs of position adjustment of the sliding wire seat 23, so as to supply the corresponding wires to the traction mechanism 4 for grabbing and traction according to the system settings, so as to provide the wires required for welding for subsequent welding work.

[0022] In some embodiments, the line driving mechanism 22 uses an electric push-pull rod, and the output end of the electric push-pull rod is connected to the sliding wire management seat.

After the stripping and cutting mechanism 3 strips and cuts the wire, the tinning mechanism 6 connected to the wire splitting mechanism 2 and the wire clamping mechanism 5 is started respectively, and the exposed core wires at the ends of the wires on the wire splitting mechanism 2 or the wire clamping mechanism 5 are driven toward the first dipping tank 65 by starting the rotary drive motor 61 and transmitting through the belt drive mechanism 62, and the moving module 64 is started to extend the exposed core wire part of the wire into the first dipping tank 65 to dip in the soldering flux. Then the moving module 64 is reset, and the wire is continued to be moved to the corresponding position of the second dipping tank by the rotary drive motor 61, and the moving module 64 is started to extend the wire so that the exposed core wires at the ends of the wires with the soldering flux attached are extended into the second dipping tank 66 for tinning. After the tinning is completed, the rotary drive motor 61 drives the turntable 63 to reset.

[0024] After the stripping and cutting mechanism 3 strips and cuts the wire, the exposed core wire at the end of the wire is in a scattered state, and is dipped in flux and tin liquid in succession to improve the subsequent welding effect of the wire on the PCB. By arranging the tinning mechanism 6 at the wire dividing mechanism 2 and the wire clamping mechanism 5, both ends of the wire are tinned, effectively improving the welding effect of the two ends of the wire.

[0025] The wire clamping mechanism 5 adopts a pneumatic clamp. When the wire needs to be clamped, the pneumatic clamp is started to clamp and fix the wire, thereby facilitating the tinning of the wire and facilitating the transfer mechanism at the rear end wire welding mechanism to take out the wire and weld it.

By setting different blade surface distances, the stripping knife 342 can be ensured to strip the rubber while avoiding cutting the core wire in the center of the wire, so as to achieve the difference in cutting effect between the stripping knife 342 and the cutting knife 343, and meet the needs of wire stripping and cutting respectively.

The traction mechanism moves to the side of the cable management seat, clamps the selected wire and moves in the direction of the stripping and cutting mechanism, and clamps and fixes the wire through the wire clamping mechanism, while releasing the traction mechanism. Then, the outer rubber layer of the wire at the stripping position is cut off by the stripping and cutting mechanism, and the core wire of the wire is cut off at the cutting position, so as to meet the demand for position adjustment of the sliding cable management seat, and then the corresponding wire is supplied to the traction mechanism for grabbing and traction according to the system setting, so as to provide the wire required for welding for subsequent welding work.
