[0024] Please see Figures 1-5In this embodiment of the utility model, a wire bonding mechanism includes a support frame, a wire bonding device, and a wire clamping device. The support frame includes a support plate 1, on which a movable plate 2 is provided and a first vertical driving component for driving the movable plate 2 to move vertically. The wire bonding device includes a movable frame 3, which is slidably disposed on the movable plate 2. The movable plate 2 is also provided with a second vertical driving component for driving the movable frame 3 to move vertically. The movable frame 3 is provided with a transverse driving component.

The wire clamping device includes a fixed frame 5, which is fixedly disposed on the movable plate 2 at a position below the movable frame 3. The fixed frame 5 is provided with a second pitch-changing module. The second pitch-changing module is provided with multiple wire clamps 6.

[0025] It should be noted that the support frame, as the supporting component of this device, provides installation positions for various components. The wire bonding device is used to solder power lines or signal lines onto the PCB board, and the wire clamping device is used to hold the power lines or signal lines. During operation, multiple wire clamps 6 grip multiple power lines or signal lines. Driven by the first vertical drive component, the wire bonding device and the wire clamping device move downwards to move the power lines or signal lines onto the PCB board. Then, driven by the second vertical drive component, the soldering gun 4 moves downwards to solder the power lines or signal lines onto the PCB board. During operation, the horizontal drive component can drive the soldering gun 4 to move horizontally to change its horizontal position, facilitating wire bonding work on different solder joints. Furthermore, the first and second pitch modules can drive each soldering gun 4 and each wire clamp 6 to move at equal intervals to adjust the spacing between each soldering gun 4 and each wire clamp 6, thereby adapting to PCB boards of different specifications.

[0026] The first vertical drive assembly includes a first screw 7, which is rotatably mounted on one side of a support plate 1. A first motor 8 is located on the other side of the support plate 1. One end of the first screw 7 is connected to the drive end of the first motor 8. A first nut 9 is mounted on the first screw 7 and connected to a movable plate 2. During operation, the first screw 7 rotates forward or backward under the drive of the first motor 8, causing the first nut 9 to reciprocate along the first screw 7, thereby causing the movable plate 2 to reciprocate vertically.

[0027] The second vertical drive assembly includes a mounting base 10, a second screw 11 rotatably mounted on the bottom of the mounting base 10, and a second motor 12 mounted on the top of the mounting base 10. The drive end of the second motor 12 is connected to one end of the second screw 11. A second nut 13 is mounted on the second screw 11 and connected to the movable frame 3. During operation, the second screw 11 rotates forward or backward under the drive of the second motor 12, thereby driving the second nut 13 to reciprocate along the second screw 11, which in turn drives the movable frame 3 to reciprocate vertically.

[0028] The lateral drive assembly includes a base plate 14, a transverse plate 15 slidably disposed on the top of the base plate 14, a first variable pitch module disposed on the top of the transverse plate 15, a drive wheel 16 and a driven wheel 17 rotatably disposed at both ends of the base plate 14, and a third motor 18 disposed at the bottom of the base plate 14.

A synchronization frame is disposed at the bottom of the transverse plate 15, and one end of the synchronization frame is clamped on the transmission belt 19. During operation, the third motor 18 drives the drive wheel 16 to rotate clockwise or counterclockwise, and the rotation of the drive wheel 16 drives the transmission belt 19 to rotate, thereby driving the base plate 14 to move laterally reciprocally.

[0029] The first pitch-changing module includes a first base 20. Two first pitch-changing platforms 21 are slidably disposed on the top of the first base 20. A first transmission spindle is rotatably disposed inside the base. The surface of the first transmission spindle is provided with two sections of first helical guide grooves. The two first pitch-changing platforms 21 are threadedly engaged with the two sections of first helical guide grooves, respectively. A fourth motor 22 is disposed on the side of the first base 20. The drive end of the fourth motor 22 is connected to one end of the first transmission spindle. A fixed platform 23 is fixedly disposed on the top of the first base 20 between the two pitch-changing platforms. There are three welding torches 4, two of which are disposed on the two first pitch-changing platforms 21, and the third welding torch 4 is disposed on the fixed platform 23. During operation, the first transmission spindle rotates forward or backward under the drive of the fourth motor 22 to drive the two first pitch-changing platforms 21 to move closer or further apart, thereby adjusting the distance between the welding torches 4.

[0030] The second pitch-changing module includes a second base 24, on the top of which six second pitch-changing platforms 25 are slidably mounted. A second drive shaft is rotatably mounted inside the base, and its surface has six sections of second helical guide grooves. The six second pitch-changing platforms 25 are threadedly engaged with the six sections of second helical guide grooves. A fifth motor 26 is mounted on the side of the second base 24, and its drive end is connected to one end of the second drive shaft. There are six wire clamps 6, each mounted on one of the six second pitch-changing platforms 25. During operation, the second drive shaft rotates forward or backward under the drive of the fifth motor 26, causing the second pitch-changing platforms 25 to move closer or further apart, thereby adjusting the spacing between the wire clamps 6.
