[0051] A welding torch, which is connected to the output end of a linear module via a drive mechanism.

[0052] A method for using a wire bonding machine with wire positioning and feeding function includes the following steps:

[0053] Step S1: By placing the wire to be welded on the upper surface of the support plate, the wire is located between the positioning block and the clamping block. As the servo motor runs, it drives the rotating disk to rotate. The inner wall of the extrusion groove on the rotating disk extrudes and pushes the connecting column. The connecting column drives the two movable blocks to move towards the center. The movable blocks use the movable rod to push the two positioning blocks to move together, extruding and fixing one end of the wire.

[0054] Step S2: As the movable block moves, it drives the fixed tube to move together. The compression spring pushes the limiting block and the connecting rod, causing the two clamping blocks to move towards the wire. The rotating roller on the clamping block squeezes the wire, and the elasticity of the compression spring pushes the connecting rod and the clamping block to press the wire tightly.

[0055] Step S3: By moving the positioning block, the first mounting block moves horizontally along the first mounting groove. When the first mounting block slides to the bend of the first mounting groove, the movable rod moves the pressing block to the fixed column. As the servo motor continues to run, it drives the movable block and the pressing block to continue moving. The arc-shaped surface of the pressing block presses against the outer wall of the fixed column, pushing the movable rod to rotate. One end of the movable rod drives the positioning block to move longitudinally. The first mounting block slides longitudinally along the inner cavity of the second mounting groove. The positioning block drives one end of the wire to move, and the position of one end of the wire is adjusted.

[0056] Step S4: At the same time, when the arc-shaped surface of the extrusion block is pressed against the outer wall of the fixed column, the movable block drives the fixed tube to continue moving, and the connecting rod and the limiting block slide in the inner cavity of the fixed tube, compressing and deforming the compression spring. By utilizing the elasticity of the compression spring, the clamping block stably clamps the other end of the wire.

[0057] The technical effects and advantages of this invention are as follows:

[0058] (1) The present invention rotates the rotating disk counterclockwise, so that the inner wall of the extrusion groove is pressed against the connecting column, the connecting column slides along the extrusion groove, and pushes the connecting column and the movable block to move horizontally. The movable block drives the movable rod and the positioning block to move together. The first mounting block moves laterally along the first mounting groove, and at the same time drives the extrusion block to move to the fixed column. The first mounting block moves to the bend of the first mounting groove. As the movable block continues to move, the arc surface of the extrusion block is pressed against the outer wall of the fixed column, which pushes the movable rod to rotate. One end of the movable rod pushes the positioning block to move longitudinally along the first mounting groove. The two positioning blocks drive the wire end to move and adjust the position of the wire end so that the wire end can be aligned with the circuit board soldering point.

[0059] (2) The present invention uses the rotation of the rotating disk to make the inner wall of the extrusion groove press against the connecting column, push the connecting column and the movable block to move horizontally, and the movable block drives the positioning block and the clamping block to move together. The two positioning blocks press and fix one end of the wire, and the outer wall of the rotating roller on the clamping block presses against the other end of the wire, thus pressing and fixing both ends of the wire, improving the stability of the wire and facilitating the welding operation of the wire.

[0060] (3) When the two movable blocks move toward the center, they drive the fixed tube to move together. The compression spring pushes the limiting block and the connecting rod. The connecting rod drives the rotating roller on the clamping block to squeeze the other end of the wire. As the movable block drives the fixed tube to move, the limiting block squeezes and deforms the compression spring. The elastic effect of the compression spring pushes the limiting block and the connecting rod outward, so that the clamping block presses and fixes the other end of the wire, improving the stability of the wire.

The first mounting groove 51 is located on one side of the upper surface of the support plate 3 and is L-shaped. The first mounting groove 51 is used to install and accommodate the first mounting block 52, allowing the first mounting block 52 to slide along the inner cavity of the first mounting groove 51. The first mounting block 52 is fixedly connected to the middle of the lower surface of the positioning block 41 and is T-shaped. The first mounting block 52 and the first mounting groove 51 are slidably interlocked.

The movable cavity 53 is located at the bottom of the bearing plate 3, and the top of the inner wall of the movable cavity 53 is in contact with the outer wall of the first mounting block 52 and the second mounting block 66. The pressing block 54 is fixedly connected to one side of the movable rod 42. The pressing block 54 is trapezoidal and moves with the movable rod 42 to push the movable rod 42 to rotate. A tension spring is rotatably connected between the pressing block 54 and the inner wall of the groove 46. When the pressing block 54 presses against the fixed post 55, it pushes the movable rod 42 to rotate.

Servo motor 59 is electrically connected to an external power supply through an external first switch to drive the rotating disk 57 to rotate. The PLC controller regulates servo motor 59 and controls the rotation angle of rotating disk 57. As rotating disk 57 rotates counterclockwise, the inner wall of extrusion groove 58 presses against connecting column 56. Connecting column 56 slides along extrusion groove 58, pushing connecting column 56 and movable block 45 to move horizontally. Movable block 45 drives movable rod 42 and positioning block. Moving together, the first mounting block 52 moves laterally along the first mounting groove 51, simultaneously moving the pressing block 54 to the fixed post 55. The first mounting block 52 moves to the bend of the first mounting groove 51. As the movable block 45 continues to move, the arc-shaped surface of the pressing block 54 presses against the outer wall of the fixed post 55, pushing the movable rod 42 to rotate. One end of the movable rod 42 pushes the positioning block 41 to move longitudinally along the first mounting groove 51.

The rotating roller 63 moves together with the clamping block 61, causing the outer wall of the rotating roller 63 to press against the other end of the wire. The rotation of the rotating roller 63 facilitates the movement of the other end of the wire between the clamping blocks 61, making it easier to push the wire. The second mounting groove 65 is provided on the upper surface of the bearing plate 3. The second mounting groove 65 is used to install and accommodate the second mounting block 66.

The compression spring 610 is located inside the fixed tube 68, with one end of the compression spring 610 in contact with the limiting block 69. When the two movable blocks 45 move toward the center, they drive the fixed tube 68 to move together. The compression spring 610 pushes the limiting block 69 and the connecting rod 67. The connecting rod 67 drives the clamping block 61 to press against the other end of the wire. As the movable block 45 moves the fixed tube 68, the limiting block 69 compresses and deforms the compression spring 610. The elasticity of the compression spring 610 pushes the limiting block 69 and the connecting rod 67 outward, so that the clamping block 61 presses and fixes the other end of the wire, improving the stability of the wire.

The welding torch 9 is electrically connected to an external power supply through an external third switch and is used to weld and fix one end of the wire and the circuit board.

[0080] A method for using a wire bonding machine with wire positioning and feeding function includes the following steps:

[0081] Step S1: By placing the wire to be welded on the upper surface of the support plate 3, the wire is located between the positioning block 41 and the clamping block 61. As the servo motor 59 runs, it drives the rotating disk 57 to rotate. The inner wall of the extrusion groove 58 on the rotating disk 57 extrudes and pushes the connecting column 56. The connecting column 56 drives the two movable blocks 45 to move towards the center. The movable blocks 45 use the movable rod 42 to push the two positioning blocks 41 to move together, extruding and fixing one end of the wire.

[0082] Step S2: As the movable block 45 moves, it drives the fixed tube 68 to move together. The compression spring 610 pushes the limiting block 69 and the connecting rod 67, causing the two clamping blocks 61 to move towards the wire. The rotating roller 63 on the clamping block 61 squeezes the wire, and the elasticity of the compression spring 610 pushes the connecting rod 67 and the clamping block 61 to press the wire tightly.

[0083] Step S3: The movement of the positioning block 41 drives the first mounting block 52 to move horizontally along the first mounting groove 51. When the first mounting block 52 slides to the bend of the first mounting groove 51, the movable rod 42 drives the pressing block 54 to move to the fixed column 55. As the servo motor 59 continues to run, it drives the movable block 45 and the pressing block 54 to continue to move. The arc-shaped surface of the pressing block 54 presses against the outer wall of the fixed column 55, pushing the movable rod 42 to rotate. One end of the movable rod 42 drives the positioning block 41 to move longitudinally. The first mounting block 52 slides longitudinally along the inner cavity of the first mounting groove 51. The positioning block 41 drives one end of the wire to move, and the position of one end of the wire is adjusted.

[0084] Step S4: At the same time, when the arc-shaped surface of the extrusion block 54 is pressed against the outer wall of the fixed column 55, the movable block 45 drives the fixed tube 68 to continue moving. The connecting rod 67 and the limiting block 69 slide in the inner cavity of the fixed tube 68, compressing and deforming the compression spring 610. The elastic effect of the compression spring 610 is used to make the clamping block 61 stably clamp the other end of the wire.

10. A method of using a wire bonding machine with wire positioning and feeding function, characterized in that, Using a wire bonding machine with wire positioning and feeding function as described in any one of claims 1-9 includes the following steps: Step S1: By placing the wire to be welded on the upper surface of the support plate (3), the wire is located between the positioning block (41) and the clamping block (61). As the servo motor (59) runs, it drives the rotating disk (57) to rotate. The inner wall of the extrusion groove (58) on the rotating disk (57) extrudes and pushes the connecting column (56). The connecting column (56) drives the two movable blocks (45) to move towards the center. The movable blocks (45) use the movable rod (42) to push the two positioning blocks (41) to move together, and extrudes and fixes one end of the wire. Step S2: As the movable block (45) moves, the fixed tube (68) moves together. The compression spring (610) pushes the limiting block (69) and the connecting rod (67) to make the two clamping blocks (61) move toward the wire. The rotating roller (63) on the clamping block (61) squeezes the wire, and the elasticity of the compression spring (610) pushes the connecting rod (67) and the clamping block (61) to press the wire tightly. Step S3: By moving the positioning block (41), the first mounting block (52) is driven to move horizontally along the first mounting groove (51). When the first mounting block (52) slides to the corner of the first mounting groove (51), the movable rod (42) drives the extrusion block (54) to move to the fixed column (55). As the servo motor (59) continues to run, it drives the movable block (45) and the extrusion block (54) to continue to move. The arc surface of the extrusion block (54) is pressed against the outer wall of the fixed column (55), pushing the movable rod (42) to rotate. One end of the movable rod (42) drives the positioning block (41) to move longitudinally. The first mounting block (52) slides longitudinally along the inner cavity of the first mounting groove (51). The positioning block (41) drives one end of the wire to move, and the position of one end of the wire is adjusted. Step S4: At the same time, when the arc surface of the extrusion block (54) is pressed against the outer wall of the fixed column (55), the movable block (45) drives the fixed tube (68) to continue moving, and the connecting rod (67) and the limiting block (69) slide in the inner cavity of the fixed tube (68), compressing and deforming the compression spring (610). By utilizing the elastic effect of the compression spring (610), the clamping block (61) stably clamps the other end of the wire.
