Description

Technical Field

[0001] The present application relates to the technical field of bonding machine wire clamps, and in particular to a bonding machine wire clamp. Background Art

[0002] In the field of chip manufacturing, the development of semiconductor packaging equipment is crucial. Bonders, as key equipment, play an indispensable role in chip manufacturing. Bonders require effective clamping of the bonding wire during processes such as arc starting, wire breakage, and wire tail retention, which is crucial for ensuring the quality and efficiency of chip manufacturing. With the continuous advancement of chip manufacturing technology, the performance requirements for bonder components are becoming increasingly stringent, particularly for the clamping device that assists in the wire bonding process.

[0003] In the related art, there are two main technical solutions to solve the problem of clamping the bonding wire in the bonding machine. One is to use the rotating shaft / shaft hole as the fulcrum for the clamping action and the solenoid as the power. Specifically, when the solenoid actuator presses the wire clamp movable piece, the wire clamp movable piece opens, the solenoid actuator leaves the wire clamp movable piece, and the wire clamp movable piece is pressed tightly against the wire clamp fixed piece by the spring; the other is to use the rotating shaft / V-groove as the fulcrum for the clamping action and use piezoelectric ceramics as the power. The wire clamp movable piece is pressed against the hinge to open the wire clamp movable piece. After the hinge leaves the wire clamp movable piece, the wire clamp movable piece is pressed tightly against the wire clamp fixed piece by the tension spring. These two solutions are widely used in the bonding process of chip manufacturing and are common means to solve the problem of clamping bonding wires in the past.

[0004] With respect to the above-mentioned related technologies, these existing technologies have obvious defects. The solution using a solenoid as the power source is prone to clamping the welding wire because the solenoid cannot perform buffering control, and the clamping force cannot be adjusted. At the same time, the solenoid has a slow movement speed, there is a gap in the matching of the rotating shaft / shaft hole, which easily causes the welding wire to twist, and the service life is also limited. The solution using piezoelectric ceramics as the power source, although it has certain advantages in terms of drive buffering control and movement speed, is high in cost, has a complex drive circuit, and has a limited service life of the rotating shaft / V-groove. Therefore, there is an urgent need for a structure that can buffer the movement of the wire clamp movable plate and increase the clamping force. Summary of the Invention

[0005] In order to buffer and control the movement of the movable piece of the wire clamp and improve the clamping force, the present application provides a bonding machine wire clamp.

[0029] The following is combined with Figure 1-4 This application is described in further detail.

[0030] The present application discloses a bonding machine wire clamp. For ease of description, this application introduces directional terms such as a first direction, a third direction, and a second direction to form a three-dimensional reference direction. The directional terms used, such as "first direction, third direction, and second direction," can be specifically described with reference to the figure, where the first direction is represented by X, the third direction is represented by Y, and the second direction is represented by Z, and the first direction, the third direction, and the second direction are perpendicular to each other.

[0031] Reference Figure 1 The bonding machine wire clamp includes a wire clamp assembly 1 and a drive assembly 2. The wire clamp assembly 1 includes a wire clamp seat 11, a movable clamp 12 and a fixed clamp 13. The fixed clamp 13 is connected to the wire clamp seat 11. A clamping area 121 is formed between the movable clamp 12 and the fixed clamp 13. The movable clamp 12 is movably connected to the fixed clamp 13 through an elastic sheet 22 to change the width of the clamping area 121. The elastic sheet 22 has a force that drives the movable clamp 12 to move away from the clamping area 121 under recoverable deformation; the movable clamp 12 rotates relative to the fixed clamp 13, and the movable clamp 12 is parallel to the first direction along the rotation axis of the fixed clamp 13. The drive assembly 2 drives the movable clamp 12 to rotate to achieve clamping of the welding wire.

[0032] Reference Figure 1The driving component 2 is arranged on one side of the wire clamp component 1, and the driving component 2 includes a voice coil motor 21. The voice coil motor 21 includes a voice coil motor stator 211 and a voice coil motor mover 212. The voice coil motor stator 211 is fixedly connected to the wire clamp seat 11, and the voice coil motor mover 212 is connected to the voice coil motor stator 211. The voice coil motor stator 211 drives the voice coil motor mover 212 to slide along the second direction, and the movable clamp 12 is fixedly connected to the side of the voice coil motor mover 212 away from the voice coil motor stator 211; the voice coil motor stator 211 drives the voice coil motor mover 212 to make a linear motion along the second direction, and the voice coil motor mover 212 moves, thereby driving the movable clamp 12 to rotate, and the elastic sheet 22 further deforms. The welding wire is clamped by the movable clamp 12 and the fixed clamp 13. The voice coil motor 21 serves as the power of the wire clamp action, which can buffer and control the clamping action, and the action speed is fast.

[0033] Reference Figure 1 and Figure 2 In order to connect the fixed clamp 13 and the clamp seat 11, the clamp assembly 1 also includes a first mounting seat 14. One side of the first mounting seat 14 is connected to the clamp seat 11, and the other side is fixedly connected to the voice coil motor mover 212 through an elastic sheet 22. Both sides of the elastic sheet 22 are penetrated with arc grooves 221 along the first direction. The two arc grooves 221 are symmetrically arranged along the second direction. The elastic sheet 22 is penetrated along the third direction to form a first mounting hole 222 for the welding wire to pass through. The movable clamp 12 and the fixed clamp 13 are arranged on the bottom wall of the first mounting seat 14. The welding wire passes through The first mounting hole 222 is located in the clamping area 121. By setting the arc groove 221, the deformation range of the elastic sheet 22 is larger, so that the rotation range of the movable clamp 12 is larger. When the voice coil motor mover 212 moves along the second direction toward the side away from the wire clamp seat 11, the elastic sheet 22 is deformed, and the movable clamp 12 rotates toward the side close to the fixed clamp 13. When the voice coil motor mover 212 slides toward the wire clamp seat 11, the elastic sheet 22 gradually returns to normal, and the movable clamp 12 rotates toward the side away from the fixed clamp 13, helping the movable clamp 12 to reset.

The first mounting seat 14 and the second mounting seat 15 are both arranged below the voice coil motor mover 212. The elastic sheet 22 is fixedly connected between the second mounting seat 15 and the first mounting seat 14. The second mounting seat 15 is fixedly connected to the voice coil motor mover 212 through a first locking bolt 151. One end of the movable clamp 12 is fixedly connected to the bottom wall of the second mounting seat 15, and one end of the fixed clamp 13 is fixedly connected to the bottom wall of the first mounting seat 14. The voice coil motor mover 212 and the movable clamp 12 are fixed by the first locking bolt 151.

[0035] Reference Figure 2 In this embodiment, the voice coil motor mover 212 is flanked by voice coil motor stators 211. The voice coil motor mover 212 and the voice coil motor stator 211 are conventional in the art and are magnetically connected. The voice coil motor stator 211 typically consists of a permanent magnet (such as neodymium iron boron) and a magnetically conductive yoke, generating a constant magnetic field. The voice coil motor mover 212 is comprised of a coil (voice coil) and a supporting structure (such as a spring or flexible mechanism). When energized, the coil is forced to move in the magnetic field. The voice coil motor stator 211 is stationary, providing a static magnetic field. When energized, the voice coil motor mover 212 reciprocates in a straight line. The magnetic field is perpendicular to the direction of motion of the voice coil motor mover 212 and is directed downward. If current flows from the left side of the coil and out from the right side, the voice coil motor mover 212 is forced to the left. If the current is reversed (flowing from the right side and out from the left side), the voice coil motor mover 212 is forced to the right.

[0036] Reference Figure 3 In order to further adjust the width of the clamping area 121, a pushing bolt 111 is provided on the side of the wire clamp seat 11 close to the voice coil motor stator 211.

One end of the pushing bolt 111 directly or indirectly abuts against the side wall of the voice coil motor mover 212 to adjust the rotation amplitude of the voice coil motor mover 212. By rotating the pushing bolt 111, the pushing bolt 111 contacts the voice coil motor mover 212 and adjusts the position of the voice coil motor mover 212, thereby adjusting and limiting the rotation amplitude of the movable clamp 12, further controlling the rotation range of the movable clamp 12, and thus better controlling the width of the clamping area 121.

[0040] Reference Figure 3 During the operation, since there may be slight height differences on the surfaces of the chip, substrate or lead, in order to enable the welding wire to adapt to differentiated working heights, the first mounting seat 14 is slidably connected to the wire clamp seat 11 along the third direction to further adjust the height of the movable clamp 12 and the fixed clamp 13 relative to the wire clamp seat 11, thereby adapting to different working heights.

[0041] Reference Figure 3 In order to make the first mounting seat 14 slide along the third direction, a sliding groove 115 is opened along the third direction on the side of the wire clamp seat 11 close to the first mounting seat 14, and a slider 141 is fixedly connected to one side of the first mounting seat 14. The slider 141 is located in the sliding groove 115 and slides along the third direction, thereby driving the movable clamp 12 and the fixed clamp 13 to slide along the third direction. In this embodiment, the sliding groove 115 is a dovetail groove and the slider 141 is a dovetail block.

The third locking bolt 16 passes through the side wall of the wire clamp seat 11 and abuts against the side wall of the slider 141. After the slider 141 slides along the third direction to the required position for the operation, the slider 141 is fixed by rotating the third locking bolt 16.

A mounting groove 116 is opened on one side of the wire clamp seat 11 along the third direction. The third mounting seat 31 is fixedly connected to the wall of the mounting groove 116 of the wire clamp seat 11 by screws. The third mounting seat 31 is arranged above the first mounting seat 14 and has a space between it and the first mounting seat 14. One side of the third mounting seat 31 is inclined toward the side of the wall of the mounting groove 116 along the direction close to the elastic sheet 22. The third mounting seat 31 is penetrated by a first wire hole 311 along its own inclined direction. One side of the wire clamp seat 11 is an arc-shaped surface, and the arc-shaped opening is arranged close to the side of the first threaded hole 112.
