Description
Technical Field
[0001] This utility model belongs to the field of chip processing technology and relates to an integrated circuit chip fixture. Background Technology
[0002] Integrated circuits (ICs), also known as microcircuits, microchips, or wafers / chips, are a way to miniaturize circuits (mainly including semiconductor devices, but also passive components) in electronics. They are often manufactured on the surface of semiconductor wafers. Integrated circuits manufactured on the surface of semiconductor chips are also called thin-film integrated circuits. Another type, thick-film integrated circuits, are miniaturized circuits composed of independent semiconductor devices and passive components integrated onto a substrate or circuit board.
[0003] In the process of manufacturing and testing integrated circuit chips, the integrated circuit chips need to be soldered onto the circuit board. During the soldering process, the solder needs to be melted onto the circuit board first using a soldering gun, and then the integrated circuit chip is fixed onto the circuit board at the position to be soldered using tweezers. Finally, the solder is remelted using a soldering gun, and the integrated circuit pins are fixedly connected to the circuit board through solidified solder. The whole operation process is quite cumbersome, resulting in low soldering efficiency. Utility Model Content

[0033] like Figures 1 to 5 As shown, an integrated circuit chip clamp includes tweezers, which include a first tweezer 1 and a second tweezer 2. The first tweezer 1 and the second tweezer 2 are hinged together. A torque mechanism is provided between the first tweezer 1 and the second tweezer 2 to drive the first tweezer 1 and the second tweezer 2 to move in opposite directions, thereby achieving the clamping of the object to be clamped. The torque mechanism includes a torsion spring 7, one end of which is connected to the first tweezer 1 and the other end of which is connected to the second tweezer 2.
[0034] The tweezers are equipped with a placement mechanism for fixing fingers. The placement mechanism includes a thumb placement groove 8 and a four-finger placement groove 9. The thumb placement groove 8 is located on the first tweezers 1, and the four-finger placement groove 9 is located on the second tweezers 2. The openings of the thumb placement groove 8 and the four-finger placement groove 9 are arranged facing each other. The positions of the thumb placement groove 8 and the four-finger placement groove 9 conform to the comfortable placement position of human fingers during work.
[0035] The tweezers bar is equipped with a welding torch 3 and a mounting mechanism for mounting the welding torch 3. The mounting mechanism includes a mounting frame 4, which has a groove 18 that matches the rotation track of the tweezers bar. The tweezers bar is equipped with a slider 19, which is located in the groove 18 and is slidably connected to the groove 18. A limiting ring 20 is provided at the end of the slider 19 away from the tweezers bar. The limiting ring 20 is fixedly sleeved on the slider 19 and is slidably connected to the mounting frame 4.

[0036] The mounting bracket 4 is provided with a sleeve 5. An adjustment mechanism is provided between the sleeve 5 and the mounting bracket 4. The adjustment mechanism includes a universal ball 16 and a ball sleeve 17. The ball sleeve 17 is fitted onto the universal ball 16 and is in frictional sliding connection with the universal ball 16. The universal ball 16 cannot detach from the ball sleeve 17.

The sleeve 5 is fitted onto the welding torch 3, and the sleeve 5 is in sliding connection with the welding torch 3. A fixed fixture is fixedly fitted onto the welding torch 3. The fixed ring 21 and the welding torch 3 are fitted with a spring 6. One end of the spring 6 is connected to the fixed ring 21 and the other end of the spring 6 is connected to the end of the sleeve 5. The fixed ring 21 facilitates the connection between the spring 6 and the welding torch 3. There is a certain friction between the universal ball 16 and the ball sleeve 17. The universal ball 16 and the ball sleeve 17 cannot rotate by the sum of the weight of the welding torch 3, the weight of the sleeve 5 and the maximum elastic force of the spring 6 alone. The universal ball 16 and the ball sleeve 17 facilitate the adjustment of the welding angle of the welding torch 3. Example
[0037] like Figures 1 to 5 As shown, an integrated circuit chip clamp includes tweezers, which include a first tweezer 1 and a second tweezer 2. The first tweezer 1 and the second tweezer 2 are hinged together. A torque mechanism is provided between the first tweezer 1 and the second tweezer 2 to drive the first tweezer 1 and the second tweezer 2 to move in opposite directions, thereby achieving the clamping of the object to be clamped. The torque mechanism includes a torsion spring 7, one end of which is connected to the first tweezer 1 and the other end of which is connected to the second tweezer 2.
[0038] The tweezers are equipped with a placement mechanism for fixing fingers. The placement mechanism includes a thumb placement groove 8 and a four-finger placement groove 9. The thumb placement groove 8 is located on the first tweezers 1, and the four-finger placement groove 9 is located on the second tweezers 2. The openings of the thumb placement groove 8 and the four-finger placement groove 9 are arranged facing each other. The positions of the thumb placement groove 8 and the four-finger placement groove 9 conform to the comfortable placement position of human fingers during work.
[0039] The tweezers bar is equipped with a welding torch 3 and a mounting mechanism for mounting the welding torch 3. The mounting mechanism includes a mounting frame 4, which has a groove 18 that matches the rotation track of the tweezers bar. The tweezers bar is equipped with a slider 19, which is located in the groove 18 and is slidably connected to the groove 18. A limiting ring 20 is provided at the end of the slider 19 away from the tweezers bar. The limiting ring 20 is fixedly sleeved on the slider 19 and is slidably connected to the mounting frame 4. The limiting ring 20 is used to prevent the slider 19 from falling out of the groove 18.
[0040] The mounting bracket 4 is equipped with a sleeve 5, and an adjustment mechanism is provided between the sleeve 5 and the mounting bracket 4. The adjustment mechanism includes a universal ball 16 and a ball sleeve 17. The ball sleeve 17 is fitted onto the universal ball 16 and is in frictional sliding connection with the universal ball 16. The ball sleeve 17 covers 60% of the surface area of the universal ball 16. The outer wall of the sleeve 5 is in contact with the universal ball 16, and the outer wall of the ball sleeve 17 is in contact with the middle of the mounting bracket 4. The sleeve 5 is fitted onto the welding torch 3, and the sleeve 5 is in sliding connection with the welding torch 3. The welding torch 3 is fixed with... The fixed sleeve is equipped with a fixing ring 21, and the welding torch 3 is equipped with a spring 6. One end of the spring 6 is connected to the fixing ring 21, and the other end of the spring 6 is connected to the end of the sleeve 5. The fixing ring 21 facilitates the connection between the spring 6 and the welding torch 3. There is a certain friction between the universal ball 16 and the ball sleeve 17. The weight of the welding torch 3 and the sleeve 5 alone cannot make the universal ball 16 and the ball sleeve 17 rotate. An additional force of 30N is required to make the universal ball 16 and the ball sleeve 17 slide.
[0041] The tweezers are equipped with a clamping rod 10 for holding 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. The locking mechanism includes a screw 11, which is inserted into the first tweezers 1 and the second tweezers 2. The screw 11 is threadedly connected to the tweezers. The head of the screw 11 is in contact with the clamping rod 10. The clamping rod 10 can be freely adjusted to adjust the angle between itself and the tweezers. The angle of the clamping rod 10 is fixed by the screw 11.
[0042] The end of the clamping rod 10 away from the tweezers is provided with a sliding rod 12 and a slide rail 13. The sliding rod 12 passes through the slide rail 13 and is slidably connected to the slide rail 13. When the chip to be clamped is clamped, the sliding rod 12 slides down to the bottom of the chip to be clamped by its own weight to prevent the chip to be clamped from slipping. When the chip needs to be placed in a designated position, the clamp is moved down. Due to the force of the placement position, the sliding rod 12 slides obliquely upward along the slide rail 13 to prevent the clamping rod 10 from obstructing the placement of the chip.
[0043] The slide rail 13 is provided with a limiting protrusion 14, and the slide rod 12 is provided with a limiting groove 15. The limiting protrusion 14 is located in the limiting groove 15 and is slidably connected with the limiting groove 15. The limiting protrusion 14 and the limiting groove 15 can prevent the slide rod 12 from sliding out of the slide rail 13.
[0044] The working method of this utility model is as follows: Place the thumb in the thumb placement groove 8 and the other four fingers in the four-finger placement groove 9, pinch the soldering gun 3 with the fingertips, and place the clamp vertically on the upper surface of the chip to be clamped. The slide bar 12 slides into the slide rail 13. The fingers bend, and the gap between the thumb and four fingers increases, causing the two clamping rods 10 to separate. Due to the obstruction of the upper surface of the chip to be clamped, the slide bar 12 cannot slide out of the slide rail 13. When the gap between the lower ends of the clamping rods 10 is equal to the distance between the two sides of the chip to be clamped, the clamping rods 10 will move to the two sides of the chip to be clamped. Due to the obstruction of the support surface of the chip, the slide bar 12 is still in the slide rail 13. At this time, the hand... With fingers extended, the gap between the thumb and four fingers narrows, and the two clamping rods 10 stably clamp the chip through the torsion spring 7. Then the chip is lifted, and the slide rod 12 slides down under the chip to be clamped by its own weight to prevent the chip from slipping. Finally, the chip is placed in the position to be soldered. Due to the force of the supporting surface, the slide rod 12 slides back into the slide rail 13. When the chip is in place, the other hand picks up the solder and places it on the pin and the area to be soldered. The fingers continue to be extended, so that the fingers are released from the placement mechanism. The soldering gun 3 is moved down, and the spring 6 is compressed so that the tip of the soldering gun 3 touches the solder and melts it. After the solder cools, the chip pins are soldered to the circuit board.
[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
