Description

Technical Field

[0001] The utility model relates to the technical field of wire bonding machines, and more specifically, to a wire clamp modification structure of a wire bonding machine. Background Art

[0002] In the existing wire bonding machine technology, the wire clamp is a key component of the wire bonding machine for wire bonding, which is used to achieve electrode connection between pads of electronic components. The main function of the wire clamp is to clamp and loosen the lead to cooperate with the work of the wire bonding machine.

[0003] The traditional wire clamp structure often cannot ensure the precise positioning of the lead wire during the clamping process, resulting in inaccurate welding position and affecting the welding quality. In addition, since the wire bonding machine needs to frequently clamp and release during operation, the traditional wire clamp structure is prone to loosening or deformation after long-term use, resulting in unstable clamping and affecting the smooth progress of welding. In response to the above problems, this device was invented. Utility Model Content

[0025] See attached Figure 1 The wire clamp modification structure of a wire welding machine of this embodiment drives a movable clamp 3 to slide on a guide rod 5 through a cylinder 8 to realize an opening and closing action with a fixed clamp 2, thereby clamping or loosening the welding wire. The structure includes a chuck 1, a fixed clamp 2 is fixedly installed on one side of the bottom of the chuck 1, and a movable clamp 3 is arranged on the other side of the bottom of the chuck 1.

[0026] See attached Figure 1 and Figure 2 Two connecting seats 4 are fixedly installed on the outer wall surfaces on both sides of the chuck 1, and the two connecting seats 4 arranged on the same side are coaxially arranged, and a guide rod 5 is fixedly installed between the two connecting seats 4 arranged on the same side. Rings 6 are fixedly installed on both sides of the top of the movable clamping piece 3, and the rings 6 on both sides are respectively slidably connected with the two guide rods 5. The two guide rods 5 ensure the stability and linearity of the movable clamping piece 3 during the sliding process, thereby improving the accuracy of welding wire clamping.

[0027] See attached Figure 2 A bracket 7 is fixedly installed on the chuck 1 at one end close to the movable clamping piece 3, and a reinforcement frame 10 is fixedly installed between the chuck 1 and the bracket 7. The reinforcement frame 10 enhances the connection strength between the chuck 1 and the bracket 7, ensures the stability of the bracket 7 during use, and prolongs the service life.

[0028] See attached Figure 1 and Figure 2 A cylinder 8 is arranged outside the movable clamp 3, and the end of the piston rod of the cylinder 8 is connected to the movable clamp 3. The bracket 7 is an L-shaped structure, and the cylinder 8 is fixedly connected to the vertical section of the bracket 7. A connecting frame 9 is arranged outside the cylinder 8, and the connecting frame 9 is fixedly installed on the bracket 7.
