[0020] Next, a further description will be given to an adjustable coaxial laser wire bonding fixture device in the present exemplary embodiment.

[0021] In an embodiment of the present application, referring to Figure 1 , the above-mentioned wire threading mechanism 1 includes a sliding platform 11 and a wire threading component 12. The wire threading component 12 is slidably arranged on the sliding platform 11 and can move along the sliding platform 11. The wire threading component 12 is provided with a wire bonding channel 123 for the wire to pass through. One end of the wire bonding channel 123 is provided with an adjustable elastic clip 13 for clamping the wire. By threading the wire through the wire bonding channel 123 and then sliding it into the clamping mechanism 2 for clamping, it can provide guidance for wire clamping and also avoid the high temperature injury caused by technicians directly manually threading into the clamping component 24. By providing an adjustable elastic clip 13 at one end of the wire bonding channel 123 for clamping the wire during the wire feeding process, it can prevent the wire from falling out of the wire bonding channel 123 when the wire threading component 12 moves, and the elastically adjustable structure can clamp wires of different sizes without causing clamping damage to the wire.

[0022] The above-mentioned clamping mechanism 2 includes a base 21, a rotating seat 22, a synchronous driving component 23 and two groups of clamping components 24. The base 21 is arranged at one end of the sliding platform 11; the rotating seat 22 is rotatably arranged on the top of the base 21 through a rotating driving component 25; both the synchronous driving component 23 and the two groups of clamping components 24 are arranged on the top of the rotating seat 22. The rotating seat 22 can drive the clamping components 24 to rotate synchronously, so as to drive the wire bonding to rotate a certain angle, and realize automatic tilt compensation when inclined welding is required. The synchronous driving component 23 is used to drive the two groups of clamping components 24 to move relatively synchronously, that is, to drive the two groups of clamping components 24 to approach or move away from each other relatively, and move the same distance to realize clamping and loosening. At the same time, the symmetry center of the two groups of clamping components 24 is opposite to the center of the wire bonding channel 123, so that the clamping components 24 can accurately clamp the wire bonding, and high coaxiality can be achieved during the welding process; wherein, the height of the rotating seat 22 is higher than the height of the sliding platform 11, so that when the rotating seat 22 drives the clamping components 24 to rotate, it will not interfere with the sliding platform 11.

[0023] As an example, referring to Figure 3 , the above-mentioned sliding platform 11 includes a base and a first slide rail 111 arranged on the base; the wire threading component 12 includes a slide plate 121 and a wire threading block 122, and the slide plate 121 is slidably connected to the first slide rail 111; the wire threading block 122 is fixed on the slide plate 121; the wire bonding channel 123 is arranged along the axis of the wire threading block 122 and is parallel to the length direction of the first slide rail 111; the slide plate 121 can move along the first slide rail 111, drive the wire bonding channel 123 to move synchronously, and then drive the wire bonding to move towards one end of the clamping mechanism 2, so as to feed the wire bonding into the clamping component 24 for clamping. The above-mentioned adjustable elastic clip 13 is arranged at one end of the wire bonding channel 123 away from the clamping mechanism 2, and includes a fixed block 131, a moving block 132 and two arc-shaped elastic pieces 133. The fixed block 131 is fixedly connected to one side of the wire threading block 122, and the moving block 132 is slidably connected to the other side of the wire threading block 122 through an adjusting screw 134 and is opposite to the fixed block 131; the two arc-shaped elastic pieces 133 are elastically arranged on the opposite side of the fixed block 131 and the moving block 132. When the wire bonding passes through the wire bonding channel 123 and makes the wire bonding extend a certain length out of the outlet of the wire bonding channel 123, the wire bonding is clamped by the adjustable elastic clip 13, and the slide plate 121 is pushed or the slide plate 121 is driven to move to the clamping mechanism 2 through a driving mechanism, and the extended end is clamped by the clamping component 24, so as to realize stable processing.

[0024] The fixed block 131 is fixedly connected to the wire threading block 122. The moving block 132 is connected to the wire threading block 122 through an adjusting screw 134, so that the distance between the moving block 132 and the fixed block 131 can be adjusted, and then the distance between the two arc-shaped elastic pieces 133 can be adjusted to adapt to wire clamping of different sizes. When clamping a wire with too large a diameter, it can avoid clamping damage to the wire caused by too small a distance between the arc-shaped elastic pieces 133. The wire is clamped by the two arc-shaped elastic pieces 133 to ensure that the wire does not fall off during the movement of the slide plate 121 driving the wire, and at the same time, it also avoids damaging the wire.

[0025] As an example, referring to Figure 2 , the above-mentioned rotation drive assembly 25 includes a rotation motor 251 and a rotating block 252. The rotation motor 251 is arranged inside the base 21; the rotating block 252 is connected to the bottom of the rotating seat 22 and is connected to the output shaft of the rotation motor 251. When the rotation motor 251 is started, it drives the rotating block 252 to rotate. The rotating block 252 drives the rotating seat 22 to rotate, thereby driving the clamping assembly 24 to rotate, and further being able to drive the wire to rotate. By connecting the rotation motor 251 to the control system, the control system drives the rotation motor 251 to rotate by the required angle.

[0026] As an example, referring to Figure 2 , the above-mentioned synchronous drive assembly 23 includes a bidirectional screw 231, a drive motor 232 and two mounting plates 233.

[0027] As an example, referring to Figure 2, the above-mentioned clamping assembly 24 includes a slider 241, a clamping block 242 and a compression spring 243. The slider 241 is slidably arranged on the rotating seat 22 along the length direction of the bidirectional screw 231. The slider 241 includes an inner cavity with an open end; the compression spring 243 is arranged at one end of the inner cavity away from its opening; the clamping block 242 is connected to the compression spring 243 through a connecting piece and is located outside the open end of the slider 241; the two sliders 241 are respectively threadedly connected to the reverse threaded parts of the bidirectional screw 231 through moving parts 244, and the two sliders 241 are symmetrically arranged with the center of the bidirectional screw 231 as the center. The driving motor 232 drives the bidirectional screw 231 to rotate, and the bidirectional screw 231 drives the two sliders 241 to move towards each other or in opposite directions by the same distance, so as to drive the two clamping blocks 242 to clamp or release the bonding wire. The two sliders 241 are symmetrically arranged with the center of the bidirectional screw 231 as the center, that is, symmetrically arranged with the center of the bonding wire channel 123, so as to achieve precise clamping of the bonding wire and ensure the coaxiality during processing. An inner cavity is provided in the slider 241, and the clamping block 242 is connected to the compression spring 243 inside it through a connecting piece, which can clamp bonding wires of different models and sizes, and can reduce the vibration impact on the bonding wire clamping caused by the operation of the equipment during processing, ensuring stable bonding wire clamping.

[0028] Specifically, the above-mentioned connecting piece includes a connecting block 245 and a connecting rod 246. The connecting block 245 is slidably connected to the inner cavity and connected to the compression spring 243, and one end of the connecting rod 246 is connected to the clamping block 242. By connecting the clamping block 242 through the connecting block 245 and the connecting rod 246, the clamping block 242 can be kept stable under the telescopic drive of the compression spring 243, thereby improving the clamping stability.

[0029] As an example, referring to Figure 2 , the opposite sides of the above two clamping blocks 242 are inclined planes, and the two inclined planes form a clamping space that is narrow at the top and wide at the bottom; the inclined planes are provided with anti-slip lines. Through the above structural design, the bonding wire can be stably clamped, preventing the bonding wire from popping out when clamped, and improving the protection effect.

[0030] As an example, a plurality of air nozzles 221 are embedded in the top surface of the above-mentioned rotating seat 22, and the plurality of air nozzles 221 are correspondingly distributed on the vertical projection area of the maximum distance between the two clamping blocks 242; a gas delivery pipe 222 is penetrated in the rotating seat 22, one end of the gas delivery pipe 222 is connected to the plurality of air nozzles 221, and the other end of the gas delivery pipe 222 extends to the outside of the rotating seat 22. The gas delivery pipe 222 is connected to an external inert gas storage tank. The inert gas, such as nitrogen, is cooled and then transported to the plurality of air nozzles 221 through the gas delivery pipe 222, and the plurality of air nozzles 221 deliver cold air to the two clamping blocks 242 to cool the clamping assembly 24, avoiding the influence of high temperature on processing. The above cooling can be carried out by any existing cooling equipment.

[0031] As an example, referring to Figure 1 , the bottom of the above-mentioned base 21 is slidably connected to the second slide rail 3, and the length direction of the second slide rail 3 is perpendicular to the length direction of the first slide rail 111. By providing the second slide rail 3, the base 21 can move on the second slide rail 3, facilitating transportation to the next process for processing.
