Description

[0001] The utility model relates to the technical field of automatic welding of circuit components, in particular to an automatic welding mechanism capable of synchronously adjusting welding points. Background Art

[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] When soldering wires to components on a PCB, there is a certain deviation in the position of the wires to be soldered on PCBs of different specifications and models. Therefore, it is generally necessary to adjust the working position of the wire clamping mechanism and the welding mechanism according to the position of the wires to be soldered. If one wire is clamped separately for soldering each time, the wire can be moved to the corresponding position for soldering, but the wires on the PCB need to be clamped and soldered one by one, which is inefficient. If multiple sets of wire clamping mechanisms are used to clamp multiple wires at the same time, the distance between different wire clamping mechanisms may be fixed. Therefore, when soldering wires to PCBs of different specifications and sizes, the wire clamping mechanisms cannot be universal and need to be adjusted and tested accordingly. The operation is troublesome, and the installation, setting, and maintenance costs are relatively high.

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

[0018] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] See also Figures 1 to 3 The utility model provides an automatic welding mechanism capable of synchronously adjusting welding points, comprising: a mobile welding platform 1, a mobile width adjustment module 2 arranged on both sides of the mobile welding platform 1, a plurality of wire clamping mechanisms 3 arranged on one side of the mobile width adjustment module 2, and a plurality of welding mechanisms 4 arranged on the other side of the mobile width adjustment module 2. The mobile width adjustment module 2 comprises: a gantry bracket 21 mounted above the mobile welding platform 1, a Y-axis mobile module 22 arranged on the gantry bracket 21, and a Y-axis mobile module 23 arranged on the Y-axis mobile module 24. A Z-axis moving module 23 on the moving end of 22, a lifting plate 24 arranged on the moving end of the Z-axis moving module 23, a width adjustment driving mechanism 25 arranged on the lifting plate 24, and a width adjustment plate 26 connected to the output end of the width adjustment driving mechanism 25, the width adjustment plate 26 is provided with a plurality of width adjustment strip holes 261, and the width adjustment strip holes 261 are arranged on the width adjustment plate 26 at different inclination angles, and the wire clamping mechanism 3 and the welding mechanism 4 are respectively movably arranged on the lifting plate 24 and connected to the width adjustment strip holes 261.

[0020] In some embodiments, the ends of the width adjustment holes 261 close to the bottom of the width adjustment plate 26 are closer to each other, while the ends close to the top of the width adjustment plate 26 are farther from each other, and the distances between the width adjustment holes 261 on the same horizontal line are the same, thereby ensuring that the distance between the wire clamping mechanism 3 or the welding mechanism 4 remains consistent during the width adjustment process.

[0021] Under normal conditions, the width adjustment plate 26 is located at the highest position, and the adjacent wire clamping mechanisms 3 or welding mechanisms 4 are at the position with the smallest relative distance, and the wire clamping mechanisms 3 or welding mechanisms 4 are retracted. After the wire clamping mechanism 3 clamps the wire to be welded, the mobile width adjustment module 2 moves the wire clamping mechanism 3 to the top of the mobile welding platform 1. The mobile welding platform 1 moves the PCB board to be welded to the bottom of the wire clamping mechanism 3 and the welding mechanism 4. When the Y-axis moving module 22 and the Z-axis moving module 23 adjust and move the positions of the wire clamping mechanism 3 and the welding mechanism 4, the width adjustment drive mechanism 25 is started to push the width adjustment plate 26 downward, thereby pushing the wire clamping mechanism 3 or the welding mechanism 4 along the Y-axis direction through the width adjustment bar hole 261, and then adjusting the distance between adjacent wire clamping mechanisms 3 or adjacent welding mechanisms 4, so as to meet the distance requirements of the welding positions when welding on the PCB board. By adopting the mobile width adjustment module 2, the width adjustment work is completed during the movement of the wire clamping mechanism 3 and the welding mechanism 4, so as to meet the welding wire distance requirements of different products, and ensure that the stripping wire feeding equipment does not need to adjust the distance between adjacent wires during feeding according to the welding position on the PCB board.

[0022] The lifting plate 24 is provided with a plurality of width adjustment rails 241 distributed in the horizontal direction, and a width adjustment slider 242 is movably mounted on the width adjustment rail 241, and the clamping mechanism 3 and the welding mechanism 4 are respectively arranged on the width adjustment slider 242. When the width adjustment driving mechanism 25 drives the width adjustment plate 26 to move, thereby driving the clamping mechanism 3 or the welding mechanism 4 to move in the Y-axis direction, the width adjustment slider 242 connected to the clamping mechanism 3 or the welding mechanism 4 moves along the width adjustment rail 241, and the width adjustment rail 241 provides guidance and limit for the movement of the width adjustment slider 242, and reduces the friction during the movement process, thereby ensuring the stability of the moving state of the clamping mechanism 3 or the welding mechanism 4 during the width adjustment process.

[0023] In some embodiments, the width adjustment drive mechanism 25 adopts a servo motor, the output end of the servo motor is connected to a screw transmission mechanism, and the motion end of the screw transmission mechanism is connected to the width adjustment plate 26.

[0024] In some embodiments, the width adjustment driving mechanism 25 adopts an electric push-pull rod, and the output rod of the electric push-pull rod is connected to the width adjustment plate 26. The electric push-pull rod has the characteristics of small size, low noise, and easy installation, and can be controlled by configuring an encoder, a frequency converter, a potentiometer, etc., so as to achieve high-precision online control, meet the requirements for position adjustment of the wire clamping mechanism 3 or the welding mechanism 4, and improve the accuracy of the width adjustment work.

[0025] A plurality of photoelectric switches 243 are arranged on the side of the lifting plate 24, and a detection baffle 263 is arranged corresponding to the photoelectric switch 243 on the width adjustment plate 26, and the detection baffle 263 passes through the detection interval of the photoelectric switch 243 in sequence as the width adjustment plate 26 moves up and down. Photoelectric switches 243 are arranged at different heights of the lifting plate 24, and detection baffles 263 are arranged on the width adjustment plate 26 corresponding to the photoelectric switch 243. When the width adjustment driving mechanism 25 drives the width adjustment plate 26 to move up and down, the detection baffle 263 passes through different detection intervals of the photoelectric switch 243 as the height position changes, so that the control system can identify and determine the height position of the current width adjustment plate 26 according to the detection information returned by the photoelectric switch 243, thereby calculating and determining the relative distance between the adjacent clamping mechanisms 3 or the adjacent welding mechanisms 4 at the current position, so as to facilitate the precise adjustment of the spacing between the clamping mechanisms 3 or the welding mechanisms 4.

[0026] The wire clamping mechanism 3 includes: an active adjustment plate 262 movably connected to the width adjustment plate 26, a pneumatic clamping jaw 31 arranged on the active adjustment plate 262, a guide cylinder 32 arranged on the pneumatic clamping jaw 31, and a guide pressing jaw 33 arranged on the output end of the guide cylinder 32, wherein the end of the guide pressing jaw 33 is provided with a V-shaped groove or a U-shaped groove, and an adjustment guide column is provided on the active adjustment plate 262, and the adjustment guide column is embedded in the width adjustment strip hole 261. When clamping the wire, the front end of the wire is limited by the V-shaped groove or the U-shaped groove of the guide pressing jaw 33 arranged at the front end of the pneumatic clamping jaw 31 to avoid the wire from being offset during the welding process. At the same time, the guide pressing jaw 33 is driven by the guide cylinder 32 to press the front end of the wire downward, so that the welding mechanism 4 can weld the front end of the wire to the PCB board or components.

The welding wire is supplied through the welding wire coil 44, and when the welding gun head 41 performs high-temperature welding, the welding wire extending from the welding wire guide head 43 is heated to a molten state, so that the exposed core wire part of the wire is welded and fixed on the PCB board, thereby ensuring the electrical connection state between the wire and the PCB board, and making the wire firmly connected to the PCB board, thereby improving the stability of the wire welding effect.

[0028] In summary, the utility model starts the width adjustment drive mechanism to push the width adjustment plate downward, thereby pushing the wire clamping mechanism or the welding mechanism along the Y-axis direction through the width adjustment bar hole, and then adjusting the distance between adjacent wire clamping mechanisms or adjacent welding mechanisms, so as to meet the distance requirements of the welding positions when welding on the PCB board.
