[0028] The tweezers rod is provided with a welding gun 3 and a mounting mechanism for installing the welding gun 3. The mounting mechanism includes a mounting frame 4. The mounting frame 4 is provided with a slide groove 18 that matches the rotating track of the tweezers rod. The tweezers rod is provided with a slider 19.

An additional force of 30N is required to cause the universal ball 16 and the ball sleeve 17 to slide.

[0030] The tweezers rod is provided with a clamping rod 10 for clamping the object to be clamped and a locking mechanism for locking the clamping rod 10. The end of the clamping rod 10 is rotatably connected to the tweezers rod; the locking mechanism includes a screw 11, which is inserted into the first tweezers rod 1 and the second tweezers rod 2.

The sliding rod 12 passes through the slide 13 and is slidably connected to the slide 13. When the chip to be clamped is clamped, the sliding rod 12 slides to the bottom of the chip to be clamped by its own gravity, which is used to prevent the chip to be clamped from sliding. When the chip needs to be placed in the specified position, the clamp is moved down. Since the sliding rod 12 is subjected to the force of the placement position, the sliding rod 12 slides obliquely upward along the slide 13 to prevent the clamping rod 10 from obstructing the placement of the chip.

[0032] A limiting protrusion 14 is provided on the slide 13, and a limiting slot 15 is provided on the slide rod 12. The limiting protrusion 14 is arranged in the limiting slot 15 and is slidably connected to the limiting slot 15. The limiting protrusion 14 and the limiting slot 15 can prevent the slide rod 12 from sliding out of the slide 13.

[0033] The working method of the present invention is as follows: the thumb is placed in the thumb placement groove 8, the other four fingers are placed in the four-finger placement groove 9, the fingertips pinch the welding gun 3, the clamp is placed vertically on the upper end surface of the chip to be clamped, the slide bar 12 slides into the slide 13, the fingers are bent, the gap between the thumb and the four fingers increases, the two clamping rods 10 are separated, and due to the obstruction of the upper end surface of the chip to be clamped, the slide bar 12 cannot slide out of the slide 13. When the gap distance between the lower ends of the clamping rods 10 is equal to the distance between the clamped two sides of the chip to be clamped, the clamping rod 10 will move to the clamped two sides of the chip to be clamped. Due to the obstruction of the support surface where the chip is placed, the slide bar 12 is still in the slide 13. At this time, the fingers Straighten it, and the gap between the thumb and four fingers will be reduced. The two clamping rods 10 will stably clamp the chip through the torsion spring 7, and then lift the chip. The slide bar 12 will slide to the bottom of the chip to be clamped by its own gravity to prevent the chip to be clamped from sliding. Finally, the chip will be placed in the position to be welded. Since the slide bar 12 is subjected to the force of the supporting surface, the slide bar 12 will slide back into the slide 13. When the chip is placed, pick up the solder with the other hand and place it on the pin and the place to be welded. The fingers continue to straighten to separate the fingers from the placement mechanism, move the welding gun 3 downward, and the spring 6 will be compressed so that the head of the welding gun 3 touches the solder, melting the solder. After the solder cools down, the chip pin and the circuit board are welded.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention.
