[0002] Laser soldering is an advanced soldering technology that uses a laser as a heat source to melt solder wire, thereby achieving the connection of solder joints.

[0003] The basic principle of laser soldering is to generate a highly concentrated beam of light by a laser, convert light energy into heat energy, thereby melting the solder wire and achieving soldering. The specific process includes preheating, feeding the solder wire, melting the solder and forming the solder joint. The solder feeding equipment delivers the solder wire to the pad position. When the pad temperature is high enough, the laser continues to irradiate, causing the solder wire to melt rapidly and flow into the tiny gap between the pad and the workpiece to be soldered, completing the solder joint formation and cooling.

[0004] Existing laser soldering wire feeding adjustment frames use guide rollers for guiding and conveying the wire. During wire return, the solder wire is prone to falling off the surface of the guide rollers, resulting in poor stability and unsuitability for solder wires of different specifications. Therefore, a new laser soldering wire feeding adjustment frame is proposed to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 - Figure 3This utility model provides an embodiment of a laser soldering wire feeding adjustment frame, including a mounting base 1 and solder wire 2. A guide assembly 3 is disposed opposite each other on the top surface of the mounting base 1, and a wire feeding assembly 4 is disposed at the center of the top of the mounting base 1. The guide assembly 3 includes mounting brackets 31 fixedly connected to the top surface of the mounting base 1. Guide rings 32 are fixedly connected between the opposite surfaces of the four mounting brackets 31. An annular groove 33 is formed on the outer surface of the guide rings 32, and a connecting groove 34 is formed through the interior of the guide rings 32. An adjusting rod 35 is disposed inside the guide rings 32. Each end of the adjusting rod 35 away from the guide rings 32 has an abutment groove 36, and an anti-slip block 37 is fixedly connected to the end of the adjusting rod 35 near the guide rings 32. The annular groove 33... An annular spring 38 is placed inside the wire feeding assembly 4. Two sets of guide components 3 are provided. The guide components 3 are arranged opposite each other on both sides of the wire feeding assembly 4. The annular groove 33 and the connecting groove 34 are interconnected. The adjusting rod 35 is slidably connected inside the connecting groove 34. The annular spring 38 abuts against the inside of the abutting groove 36. The solder wire 2 is passed through several anti-slip blocks 37. During this process, the solder wire 2 squeezes the anti-slip blocks 37, thereby driving the adjusting rod 35 to slide inside the connecting groove 34, causing the annular spring 38 to stretch. The annular spring 38 provides a stable guiding effect on the solder wire 2 through the adjusting rod 35 and the anti-slip blocks 37, so that the solder wire 2 is always between several anti-slip blocks 37 during the conveying process, thereby ensuring the stability of the solder wire 2 during the conveying process.

[0024] Reference Figure 1 - Figure 3The wire feeding assembly 4 includes a first mounting plate 41 and a second mounting plate 42 fixedly connected to the top surface of the mounting base 1. A motor base 43 is fixedly connected to the surface of the first mounting plate 41, and a drive motor 44 is fixedly connected to the surface of the motor base 43. Mounting blocks 45 are fixedly connected to the surface of the first mounting plate 41 perpendicularly. A pressure roller 46 is rotatably connected between the opposing surfaces of the two mounting blocks 45. A first guide groove 47 is formed on the surface of the second mounting plate 42, and a second guide groove 48 is symmetrically formed on the surface of the second mounting plate 42. Guide rods 49 are symmetrically arranged inside the second mounting plate 42. A pressure block 411 is fixedly connected to one end of each guide rod 49 near the pressure roller 46. A limit plate 412 is fixedly connected to the surface of each guide rod 49. An adjusting spring 413 is sleeved on the surface of each guide rod 49. A pull rod 414 is fixedly connected to one end of the limit plate 412 near the second mounting plate 42. The output shaft of the drive motor 44 is fixedly connected to the bottom of the pressure roller 46. The guide rods 49 are slidably connected to... Inside the second guide groove 48, the adjusting spring 413 is fixedly connected between the opposing surfaces of the limiting plate 412 and the second mounting plate 42. The pull rod 414 is slidably connected inside the first guide groove 47. The pressure block 411 and the pressure roller 46 are on the same horizontal line. The anti-slip block 37, the pressure block 411, and the pressure roller 46 all abut against the surface of the tin wire 2. Pulling the pull rod 414 causes the limiting plate 412 to move towards the second mounting plate 42, thereby driving the guide rod 49 inside the second guide groove 48. Sliding, at this time the adjusting spring 413 retracts, driving the pressure block 411 to move towards the second mounting plate 42, so that the solder wire 2 abuts against the surface of the pressure roller 46. At this time, the pull rod 414 is released, and the adjusting spring 413 drives the limit plate 412 to perform the reset work, so that the pressure block 411 abuts against the surface of the solder wire 2. Since the pressure block 411 is set on both sides of the pressure roller 46, the pressure block 411 can firmly abut the solder wire 2 against the surface of the pressure roller 46 under the elastic force of the adjusting spring 413.

[0025] Working principle: First, the solder wire 2 is passed through several anti-slip blocks 37. During this process, the solder wire 2 compresses the anti-slip blocks 37, thereby causing the adjusting rod 35 to slide inside the connecting groove 34, stretching the annular spring 38. The annular spring 38 provides stable guidance for the solder wire 2 through the adjusting rod 35 and the anti-slip blocks 37, ensuring that the solder wire 2 remains between the anti-slip blocks 37 during the conveying process. This guarantees the stability of the solder wire 2 during the conveying process and prevents the solder wire 2 from falling off the surface of the traditional guide roller during wire return. Then, the pull rod 414 is pulled, causing the limiting plate 412 to move towards the second mounting plate 42, thereby causing the guide rod 49 to slide inside the second guide groove 48. At this time, the adjusting spring 413 contracts, causing the pressure block 411 to move towards the second mounting plate 42, pressing the solder wire 2 against the pressure block. On the surface of the feeding roller 46, at this time, the pull rod 414 is released, and the adjusting spring 413 drives the limiting plate 412 to reset, so that the pressure block 411 abuts against the surface of the solder wire 2. Since the pressure block 411 is set on both sides of the feeding roller 46, the pressure block 411 can firmly abut the solder wire 2 against the surface of the feeding roller 46 under the elastic force of the adjusting spring 413. Then, the solder wire 2 is passed through several anti-slip blocks 37 on the other side, and the drive motor 44 is started to drive the feeding roller 46 to rotate, so that the solder wire 2 can be conveyed. Through the cooperation of the guide assembly 3 and the wire feeding assembly 4, the device is easy to adjust to convey solder wire 2 of different specifications. When changing solder wire 2 of different specifications, it is only necessary to pull the pull rod 414 to complete the replacement. The device has a compact structure and simple operation, thus improving the practicality of the device.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
