[0033] In the following, a further description will be given to the adjustable coaxial laser solder wire clamp device in the present exemplary embodiment.

[0034] In the embodiment of the present application, referring to Figure 1 The threading mechanism 1 includes the sliding platform 11 and the threading assembly 12, the threading assembly 12 is slidingly arranged on the sliding platform 11 and can move along the sliding platform 11. The threading assembly 12 is provided with the solder wire passage 123 for threading the solder wire. One end of the solder wire passage 123 is provided with the adjustable elastic clamp 13 for clamping the solder wire. By threading the solder wire into the solder wire passage 123 and then slidingly feeding into the clamping mechanism 2 for clamping, the solder wire can be guided, and the technician can be prevented from directly manually threading into the clamping assembly 24 to cause high temperature injury. By arranging the adjustable elastic clamp 13 at one end of the solder wire passage 123, the solder wire can be clamped during the feeding process, the solder wire can be prevented from falling off from the solder wire passage 123 when the threading assembly 12 moves, and the elastic adjustable structure can clamp the solder wire of different sizes without causing clamping damage to the solder wire.

[0035] The aforementioned clamping mechanism 2 includes a base 21, a rotating seat 22, a synchronous drive assembly 23, and two sets of clamping assemblies 24. The base 21 is located at one end of the sliding platform 11. The rotating seat 22 is rotatably mounted on top of the base 21 via the rotary drive assembly 25. The synchronous drive assembly 23 and the two sets of clamping assemblies 24 are both located on top of the rotating seat 22. The rotating seat 22 can drive the clamping assemblies 24 to rotate synchronously, thereby causing the welding wire to rotate at a certain angle, achieving automatic tilt compensation when tilt welding is required. The synchronous drive assembly 23 is used to drive the two sets of clamping assemblies 24 to move synchronously relative to each other, that is, to drive the two sets of clamping assemblies 24 to move closer or further away from each other by the same distance, thereby achieving clamping and releasing. At the same time, the symmetry center of the two sets of clamping assemblies 24 is opposite to the center of the welding wire channel 123, so that the clamping assemblies 24 can accurately clamp the welding wire and achieve high coaxiality during welding processing. 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 assemblies 24 to rotate, it will not interfere with the sliding platform 11.

[0036] As an example, refer to Figure 3 The aforementioned sliding platform 11 includes a base and a first slide rail 111 disposed on the base; the wire threading assembly 12 includes a sliding plate 121 and a wire threading block 122, the sliding plate 121 being slidably connected to the first slide rail 111; the wire threading block 122 being fixed on the sliding plate 121; the wire bonding channel 123 being disposed along the axial direction of the wire threading block 122 and parallel to the length direction of the first slide rail 111; the sliding plate 121 being able to move along the first slide rail 111, driving the wire bonding channel 123 to move synchronously, thereby driving the wire bonding to move toward one end of the clamping mechanism 2, thereby feeding the wire bonding into the clamping assembly 24 for clamping. The aforementioned adjustable elastic clip 13 is disposed at the end of the wire bonding channel 123 away from the clamping mechanism 2, and includes a fixed block 131, a movable block 132, and two arc-shaped spring pieces 133. The fixed block 131 is fixedly connected to one side of the wire threading block 122, and the movable block 132 is slidably connected to the other side of the wire threading block 122 via an adjusting screw 134 and is opposite to the fixed block 131. The two arc-shaped spring pieces 133 are elastically disposed on opposite sides of the fixed block 131 and the movable block 132. When the wire bonding enters from the wire bonding channel 123 and extends a certain length out of the outlet of the wire bonding channel 123, the wire bonding is clamped by the adjustable elastic clip 13, pushing the slide plate 121 or driving the slide plate 121 to move it to the clamping mechanism 2. Its protruding end is clamped by the clamping assembly 24, thereby achieving stable processing.

[0037] The fixed block 131 is fixedly connected to the wire threading block 122. The movable block 132 is connected to the wire threading block 122 via an adjusting screw 134, allowing adjustment of the distance between the movable block 132 and the fixed block 131. This, in turn, adjusts the distance between the two arc-shaped spring pieces 133 to accommodate different sizes of bonding wires. This prevents damage to the bonding wire caused by the insufficient spacing of the arc-shaped spring pieces 133 when clamping bonding wires with excessively large diameters. By clamping the bonding wire with the two arc-shaped spring pieces 133, the bonding wire is prevented from falling off during the movement of the sliding plate 121, while also avoiding damage to the bonding wire.

[0038] As an example, refer to Figure 2 The aforementioned rotary drive assembly 25 includes a rotary motor 251 and a rotating block 252. The rotary motor 251 is disposed 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 rotary motor 251. When the rotary motor 251 is started, it drives the rotating block 252 to rotate, which in turn drives the rotating seat 22 to rotate, thereby driving the clamping assembly 24 to rotate, and in turn driving the bonding wire to rotate. By connecting the rotary motor 251 to the control system, the control system drives the rotary motor 251 to rotate by the required angle.

[0039] As an example, refer to Figure 2 The aforementioned synchronous drive assembly 23 includes a bidirectional screw 231, a drive motor 232, and two mounting plates 233. The two mounting plates 233 are vertically connected to the rotating base 22 and are arranged opposite to each other. The drive motor 232 is mounted on one of the mounting plates 233. The two ends of the bidirectional screw 231 are rotatably connected to the two mounting plates 233 respectively, and one end of the bidirectional screw 231 is connected to the output end of the drive motor 232. The center of the bidirectional screw 231 corresponds to the axial centerline of the wire bonding channel 123.

[0040] As an example, refer to Figure 2The aforementioned clamping assembly 24 includes a slider 241, a clamping block 242, and a compression spring 243. The slider 241 is slidably disposed on the rotating seat 22 along the length direction of the bidirectional screw 231, and the slider 241 includes an inner cavity with one end open. The compression spring 243 is disposed at the end of the inner cavity away from its opening. The clamping block 242 is connected to the compression spring 243 through a connector and is located outside the open end of the slider 241. The two sliders 241 are respectively threaded to the reverse threaded portion of the bidirectional screw 231 through a moving member 244, and the two sliders 241 are respectively arranged symmetrically about the center of the bidirectional screw 231. The drive motor 232 drives the bidirectional screw 231 to rotate, and the bidirectional screw 231 drives the two sliders 241 to move the same distance in opposite directions, thereby causing the two clamping blocks 242 to clamp or release the welding wire. The two sliders 241 are symmetrically arranged around the center of the bidirectional screw 231, that is, symmetrically arranged around the center of the wire bonding channel 123, to achieve precise clamping of the wire bonding and ensure coaxiality during processing. An inner cavity is provided in the slider 241, and the clamping block 242 is connected to its internal compression spring 243 via a connector. This allows for clamping of wire bonding of different sizes and can reduce the vibration caused by equipment operation during processing, ensuring stable wire bonding clamping.

[0041] Specifically, the aforementioned connector 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 with the connecting block 245 and the connecting rod 246, the stability of the clamping block 242 under the extension and retraction of the compression spring 243 can be improved, thereby enhancing clamping stability.

[0042] As an example, refer to Figure 2 The two clamping blocks 242 have opposite sides that are sloped, forming a clamping space that is narrower at the top and wider at the bottom; the sloped surfaces are provided with anti-slip texture. Through the above structural design, the welding wire can be stably clamped, preventing the welding wire from popping outwards when clamped, thus improving the protection effect.

[0043] As an example, the top surface of the rotary seat 22 is embedded with multiple air nozzles 221, which are distributed on the vertical projection area of ​​the two clamping blocks 242 at their farthest distance. A gas delivery pipe 222 passes through the rotary seat 22, with one end connected to the multiple air nozzles 221 and the other end extending to the outside of the rotary seat 22. The gas delivery pipe 222 is connected to an external inert gas storage tank, through which inert gas, such as nitrogen, is cooled and delivered to the multiple air nozzles 221. The multiple air nozzles 221 then deliver cool air to the two clamping blocks 242 to cool the clamping assembly 24, thus preventing high temperatures from affecting the processing. The cooling can be performed using any existing refrigeration equipment.

[0044] As an example, refer to Figure 1 The bottom of the 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 setting the second slide rail 3, the base 21 can move on the second slide rail 3, which facilitates its transport to the next process for processing.

[0045] As an example, multiple sets of clamping mechanisms 2 are provided, and these multiple sets of clamping mechanisms 2 are slidably arranged at intervals on the second slide rail 3; multiple sets of wire threading assemblies 12 are provided, and these multiple sets of wire threading assemblies 12 are slidably arranged at intervals on the first slide rail 111. By providing multiple sets of clamping mechanisms 2 and multiple sets of wire threading assemblies 12, multiple bonding wires can be clamped and threaded simultaneously, and then fed into the next process at intervals via the second slide rail 3, greatly improving processing efficiency.
