It adopts a dual-vision positioning and capturing system, which can accurately identify objects and realize arbitrary placement of products without the need for fixtures. The laser is transmitted through optical fiber and uses an optical system to perform one-time full-plate laser welding. The solder paste can be automatically and quickly applied. Laser solder paste welding is a laser welding technology that uses laser as a heat source to heat the solder paste to melt. It has a real-time temperature feedback system that can control the temperature of the solder joint in real time to meet the different welding requirements of the welding workpiece and ensure the welding yield. It has an automatic constant temperature welding function and adopts non-contact preheating solder paste welding. It can also meet the needs of different workpieces for complex solder joints, which reduces manual operation to a certain extent and facilitates production. It uses CCD high-definition industrial cameras for positioning, which saves manual placement. The time is saved and the work efficiency is improved. The support columns 2 are evenly distributed at the four corners of the bottom of the body 1. The electrical panel 3 can be disassembled, which is more convenient for disassembly and maintenance of the electrical panel 3, so as to prevent the inconvenience of maintenance of the electrical components inside the body 1 due to the inconvenience of disassembly of the electrical panel 3 after long-term use. The operating platform 4 is set as a drawer-type sliding connection on the surface of the body 1, which is more convenient for the operating platform 4 to be stored, and avoids the operating platform 4 being exposed to the outside all the time and causing inconvenience in the operation of the body 1 due to unintentional touch by the staff. The working platform 8 is symmetrically distributed at the left and right ends of the top of the base 7, and the working platform 8 is slidably connected to the body 1, which is more convenient for the working platform 8 to slide, so as to prevent the working platform 8 from being stuck by the body 1 during use. In the case where the platform 8 cannot continue to slide, the X-axis 9 is slidably connected to the machine body 1, and the Y-axis 10 is slidably connected to the machine body 1, which makes it easier for the X-axis 9 and the Y-axis 10 to slide, and avoids the X-axis 9 and the Y-axis 10 being stuck by the machine body 1 during use, which causes the X-axis 9 and the Y-axis 10 to be unable to slide further. The Z-axis 11 is slidably connected to the machine body 1, and the Z-axis 11 is slidably connected to the working platform 8, which makes it easier for the Z-axis 11 to slide, and avoids the Z-axis 11 being stuck by the machine body 1 during use, which causes the Z-axis 11 to be unable to slide further. The coaxial laser device 13 is slidably connected to the working platform 8, and the coaxial laser device 13 is slidably connected to the machine body 1.It is more convenient for the coaxial laser device 13 to slide, and avoids the coaxial laser device 13 being stuck by the working platform 8 or the body 1 during use, which causes the coaxial laser device 13 to be unable to continue sliding.

[0021] Working principle: When in use, first place the machine body 1 at the required position, so that the support column 2 can support the machine body 1 steadily, and then place the workpiece on the top of the working platform 8. Then, pinch the operating platform 4 and pull it backwards to make the operating platform 4 completely slide out of the inside of the machine body 1, and then adjust the working platform 8 to make the working platform 8 slide on the top of the base 7. When the working platform 8 drives the workpiece to slide to the position of the coaxial laser device 13, the machine body 1 can be started through the operating platform 4, so that the camera A6 can preliminarily locate the product feature capture, and preliminarily match the coaxial laser device 13 to the workpiece through the X-axis 9 and the Y-axis 10, and then the camera B14 will locate the product again. A second snapshot is taken above the product and then accurately positioned through the Z motion axis 11, and then the screw valve body 12 is used to accurately control the tin to place the solder paste on the set pad. After the tin is applied, the coaxial laser device 13 will be positioned above the solder paste point to emit light to heat and melt the solder paste. The laser will automatically stop after the set time and temperature are reached. The melted solder paste will cool down to form a solder point after the temperature drops, completing the welding process. During the soldering process, the data can be displayed on the display screen 5, and after long-term use, when the electrical components inside the body 1 need to be maintained, the electrical panel 3 can be removed from the right side of the body 1 with the help of tools, so that the staff can maintain the electrical components inside the body 1.
