[0022] Please see Figures 1-6 A multi-point rotatable wire bonding machine includes a control console 1, a processing table 2 and a wire bonding head 3. A linear module 4 is fixed on the top of the control console 1. A front-to-back moving mechanism 5 is provided on the top of the moving part of the linear module 4. A vertical moving mechanism 6 is provided on the surface of the front-to-back moving mechanism 5. A rotating mechanism 7 is provided on the surface of the vertical moving mechanism 6.

[0023] The rotating mechanism 7 includes a C-shaped plate 701. A first motor 702 is fixed to the bottom of the C-shaped plate 701. The output shaft of the first motor 702 passes through the C-shaped plate 701 and is fixed to a mounting platform 703. A worm gear 704 is rotatably connected to the inner wall surface of the mounting platform 703. Two side plates 705 are fixed to the surface of the mounting platform 703. A transmission shaft 707 is rotatably connected between the two side plates 705. A worm wheel 706 and an extension plate 708 are fixed to the surface of the transmission shaft 707. The worm gear 704 meshes with the worm wheel 706. A movable seat 719 is fixed to the surface of the extension plate 708. The movable seat 719 is slidably connected to the surface of the side plate 705. An electric turntable 709 is fixed to the surface of the movable seat 719. A mounting plate 710 is fixed to the surface of the electric turntable 709. A welding wire head 3 is installed on the surface of the mounting plate 710. A transmission structure is provided on the top of the mounting platform 703.

[0024] When the first motor 702 is working, it can drive the mounting platform 703 to rotate, achieving a basic single-axis rotation effect. When the transmission structure is working, the worm gear 704 will drive the worm wheel 706 to rotate, which allows the extension plate 708 to drive the movable seat 719 to rotate upward or downward, giving the welding head 3 a dual-axis rotation effect. When the electric turntable 709 is working, it can drive the mounting plate 710 to rotate left and right, further expanding the range of rotation of the welding head 3. Through the multi-axis rotation function of the welding head 3, welding operations can be performed at different angles and positions without frequently moving the workpiece or adjusting the position of the welding machine. It can easily cope with complex-shaped workpieces and welding requirements at different angles, and also allows the welding head 3 to accurately align with the welding point, reducing welding defects caused by angular deviation.

[0025] Furthermore, the top transmission structure of the mounting platform 703 includes a second motor 711, which is fixed to the top of the mounting platform 703. The output shaft of the second motor 711 passes through the mounting platform 703. Pulleys 712 are fixed above the surface of the worm gear 704 and the surface of the output shaft of the second motor 711. The two pulleys 712 are connected by belt drive.

[0026] When the second motor 711 starts, it can drive the pulley 712 on the surface of its output shaft to rotate. The pulley 712 can then drive the worm 704 to rotate synchronously through the belt drive, ensuring that the worm 704 can rotate normally when the second motor 711 starts.

[0027] Furthermore, an auxiliary rod 713 is fixed to the top of the mounting platform 703, and the auxiliary rod 713 is rotatably connected to the surface of the C-shaped plate 701.

[0028] This design ensures good stability on the upper surface of the mounting platform 703, improving the rotational accuracy of the mounting platform 703.

[0029] Furthermore, a guide plate 714 is fixed to the surface of the side plate 705, and a sliding groove is provided on the surface of the movable seat 719 to cooperate with the guide plate 714. The guide plate 714 is slidably connected to the surface of the sliding groove.

[0030] When the drive shaft 707 drives the movable seat 719 to rotate via the extension plate 708, the movable seat 719 slides on the surface of the side plate 705, and the guide plate 714 also slides on the surface of the groove. This ensures that the movable seat 719 will not move left or right.

[0031] Furthermore, the front and rear moving mechanism 5 includes a mounting column 501. The bottom of the mounting column 501 is fixedly connected to the surface of the moving part of the linear module 4. A mounting frame 502 is fixed on the surface of the mounting column 501. A first cylinder 503 is fixed at the top and bottom of the mounting frame 502. Multiple guide rods 504 slide through the surface of the mounting frame 502.

[0032] The linear module 4 can drive the mounting column 501 to move left and right. When the first cylinder 503 is working, it can drive the vertical moving mechanism 6 to move back and forth, so that the front and back positions of the welding head 3 can be adjusted. When the vertical moving mechanism 6 moves, the guide rod 504 will slide on the surface of the mounting frame 502, which helps to improve the stability of the vertical moving mechanism 6 when it moves and ensures that the vertical moving mechanism 6 moves in a straight line.

[0033] Furthermore, the vertical moving mechanism 6 includes a combination plate 601, which is fixedly connected to one end of the first cylinder 503. The surface of the combination plate 601 is fixedly connected to one end of the guide rod 504. A second cylinder 602 is fixedly fixed to the top of the combination plate 601. One end of the second cylinder 602 passes through the combination plate 601 and is fixedly connected to a sliding seat 603. The surface of the sliding seat 603 is slidably connected to the surface of the combination plate 601, and the surface of the sliding seat 603 is fixedly connected to the surface of the C-shaped plate 701.

[0034] When the second cylinder 602 is started, it can drive the sliding seat 603 to slide up and down on the surface of the combination plate 601, thereby changing the vertical height position of the welding wire head 3 and further improving the flexibility of the welding wire head 3 when in use.

[0035] Furthermore, a first circular guide rail 715 is fixed to the surface of the C-shaped plate 701, and a first slider 716 is slidably connected to the surface of the first circular guide rail 715. The top of the first slider 716 is fixedly connected to the bottom of the mounting platform 703. A second circular guide rail 717 is fixed to the surface of the movable seat 719, and a second slider 718 is slidably connected to the surface of the second circular guide rail 717. The surface of the second slider 718 is fixedly connected to the surface of the mounting plate 710.

[0036] When the first motor 702 drives the mounting platform 703 to rotate, the first slider 716 will slide along the mounting platform 703 on the surface of the first circular guide rail 715. When the electric turntable 709 drives the mounting plate 710 to rotate, the second slider 718 will slide on the surface of the second circular guide rail 717. This helps to maintain the center position of the mounting platform 703 and the mounting plate 710, making their rotation more stable, reducing wobbling and improving rotation accuracy.

[0037] The control console 1 is equipped with a controller, which is electrically connected to the first motor 702, the second motor 711, the electric turntable 709, the second cylinder 602, the first cylinder 503 and the linear module 4.

[0038] The internal controller of console 1 can operate multiple devices.

[0039] Working principle: The left and right positions of the welding head 3 can be adjusted by the linear module 4. When the first cylinder 503 is working, the front and back positions of the welding head 3 can be adjusted. When the second cylinder 602 is working, the height position of the welding head 3 can also be adjusted. When the rotation angle of the welding head 3 needs to be adjusted, the first motor 702 drives the mounting platform 703 to rotate, achieving a basic single-axis rotation effect. When the second motor 711 is working, the worm gear 704 will drive the worm wheel 706 to rotate, which allows the extension plate 708 to drive the movable seat. 719 rotates upwards or downwards, giving the wire bonding head 3 a dual-axis rotation effect. When working, the electric turntable 709 can drive the mounting plate 710 to rotate left and right, further expanding the range of rotation of the wire bonding head 3. Through the multi-axis rotation function of the wire bonding head 3, welding operations can be performed at different angles and positions without frequently moving the workpiece or adjusting the position of the wire bonding machine. It can easily handle workpieces with complex shapes and welding requirements at different angles, and also allows the wire bonding head 3 to be precisely aligned with the weld point, reducing welding defects caused by angular deviations.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
