Description

Technical Field

[0001] The utility model relates to the technical field of welding splitters, in particular to a wire threading hole of a vertically-incoming wire splitter. Background Art

[0002] The welding splitter is also known as a wedge welding splitter, a vertical needle or a steel nozzle splitter, and is one of the core components used in the wire bonding technology. It is mainly used for welding chips. The material of the welding splitter is usually ceramic, which has good wear resistance and high temperature resistance and can meet the requirements of high-precision bonding. In addition, the selection and performance of the welding splitter play a decisive role in the flexibility, reliability and economy of bonding.

[0003] During the wire feeding process of the traditional welding splitter by a fully automatic wire bonder, the welding wire needs to enter the wire threading holes in the welding splitter. There are multiple wire threading holes for the welding wire to pass through. Due to the fast wire feeding speed, the movement of the welding wire will be unstable and it will vibrate in the wire threading holes. When vibration occurs, it will affect the subsequent work of the welding wire, resulting in inaccurate welding work. The sizes of the inlet and outlet of the wire threading holes are different, and due to the volume difference, the welding wire cannot be stably transmitted. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a wire threading hole of a vertically-incoming wire splitter.

[0005] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0006] A wire threading hole of a vertically-incoming wire splitter includes a main body. A first limiting structure is arranged at the top end of the main body, and a second limiting structure is arranged at the bottom of the main body;

[0007] A first wire inlet hole vertically penetrates through the main body. The first wire inlet hole includes an inlet conical hole, a middle long conical hole and a bottom outlet cylindrical hole.

[0008] Preferably, the first limiting structure includes a first clamp embedded in the inner wall of the inlet conical hole. A second clamp is arranged directly above the first clamp in alignment, and the back of the second clamp is tightly fixed on a fixing plate.

A clamping plate is formed on the outer wall of the movable plate, and a pressing rod is vertically slidably installed in the inner wall of the fixing plate.

[0010] Preferably, the bottom of the pressing rod is movably connected to a compression rod. A spring is extruded in the compression rod. A clamping block is nested and fixed on the outer wall of the pressing rod, and the clamping block is used in cooperation with the clamping plate for clamping connection.

[0011] Preferably, the second limiting structure includes a clamping box fixed to the bottom of the main body. Symmetrically fixed inside the inner wall of the clamping box are telescopic rods, and an arc-shaped plate is detachably installed on the telescopic joints of the telescopic rods.

[0012] Preferably, a welding end is formed at the bottom of the main body. A V-groove is formed on the welding end, and a spherical segment-shaped through groove is formed at one end of the bottom of the V-groove.

[0013] Preferably, a second wire inlet hole and a third wire inlet hole that are connected are penetrated through the other side of the bottom of the V-groove.

[0014] The beneficial technical effects of the present utility model:

[0015] By providing a novel wire inlet hole on the traditional welding split knife, the wire inlet hole is composed of an inlet conical hole, a middle long conical hole, and an outlet cylindrical hole, enabling the welding wire to have a smooth transition space when passing through the wire hole.

[0029] To make the technical solutions of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings, but the implementation manners of the present utility model are not limited thereto.

[0030] As Figures 1-9 shown, a wire threading hole of a vertical inlet split blade provided in this embodiment includes a main body 1. A first limiting structure 3 is provided at the top end of the main body 1, and a second limiting structure 2 is provided at the bottom end of the main body 1. A first wire inlet hole 101 vertically penetrates through the main body 1. The first wire inlet hole 101 includes an inlet conical hole, a middle long conical hole, and a bottom outlet cylindrical hole. The welding end of the main body 1 gradually shrinks, and half of the welding end is provided in a cross-sectional shape.

[0031] The first limiting structure 3 includes a first clamp 301 embedded in the inner wall of the inlet conical hole. A second clamp 302 is arranged directly above the first clamp 301 in alignment, and the back of the second clamp 302 is closely fixed on the fixed plate 309.

[0032] A positioning hole 306 horizontally penetrates through the inner wall of the fixed plate 309. A movable plate 303 is slidably connected in the positioning hole 306. A clamping plate 304 is formed on the outer wall of the movable plate 303. A pressing rod 305 is vertically slidably installed in the inner wall of the fixed plate 309.

[0033] The bottom of the pressing rod 305 is movably connected to a compression rod 308. A spring is squeezed inside the compression rod 308. A clamping block 307 is nested and fixed on the outer wall of the pressing rod 305. The clamping block 307 is used in cooperation with the clamping plate 304 for clamping connection. When the pressing rod 305 is pressed downward, the compression rod 308 is stressed and contracts, causing the clamping block 307 to disengage from the groove of the clamping plate 304. The disengagement of the clamping block 307 allows the movable plate 303 to move.

[0034] The second limiting structure 2 includes a clamping box 203 fixed to the bottom of the main body 1. The middle of the clamping box 203 is circularly hollowed out. Telescopic rods 202 are symmetrically fixed in the inner wall of the clamping box 203. An arc-shaped plate 201 is detachably installed on the telescopic joints of the telescopic rods 202.

[0035] A welding end is formed at the bottom of the main body 1. The welding end is in the shape of an equilateral trapezoid as a whole and is closely installed with the clamping box 203. A V-groove 104 is opened on the welding end. A spherical segment-shaped through-hole 105 is formed at one end of the bottom side of the V-groove 104.

[0036] On the other side of the bottom of the V-groove 104, a second wire inlet hole 102 and a third wire inlet hole 103 are connected through. The second wire inlet hole 102 is arranged at the center position on the right side of the welding end. The third wire inlet hole 103 extends into the interior of the welding end, and the end of the third wire inlet hole 103 extends upward.

[0037] The working principle of this device:

[0038] The first step: When this device is specifically used, the welding wire enters from the conical inlet hole of the first wire inlet hole 101 at the top of the main body 1. Under the limiting action of the first clamp 301 and the second clamp 302 in the first limiting structure 3, the welding wire enters the interior from the center of the first wire inlet hole 101 and extends downward. As the diameter of the long conical hole in the middle of the first wire inlet hole 101 gradually becomes smaller, it enters and clings to the hole wall and enters the cylindrical thin hole at the bottom, and then vertically enters the clamping box 203.

[0039] The second step: In the clamping box 203, the arc-shaped plate 201 and the telescopic rod 202 perform a second limiting adjustment on the entering welding wire, and then discharge it. After manual guidance, it passes through the second wire inlet hole 102 and the third wire inlet hole 103 and reaches the welding end.

[0040] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the scope disclosed by the present invention, according to the technical solution and its concept of the present invention, makes equivalent substitutions or changes, and all belong to the protection scope of the present invention.
