[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-6As shown, an online laser soldering machine provided by an embodiment of the present invention includes a profile frame 1, a welding detection component 17 is arranged inside the profile frame 1, the welding detection component 17 includes two support plates 18, a linear motor 19 is installed on the outer wall of one side of the top of the two support plates 18 by bolts, and the output ends of the two linear motors 19 are installed with a sliding frame 20 by bolts, a linear motor 21 is installed on the outer wall of one side of the sliding frame 20 by bolts, and the output end of the linear motor 21 is installed with a connecting frame 23 by bolts, a linear motor 3 22 is installed on the outer wall of one side of the connecting frame 23 by bolts, and the output end of the linear motor 3 22 is respectively installed with a tin feeder 24, a tin sucker 25, a laser 26 and an industrial camera 27 by bolts, a control box 16 is installed inside the profile frame 1 by bolts, and the control box 16 is electrically connected to the tin feeder 24, the tin sucker 25, the laser 26 and the industrial camera 27 through wires.

[0032] Specifically, in this embodiment, a profile frame 1 is included, and a welding detection assembly 17 is provided inside the profile frame 1. The welding detection assembly 17 includes two support plates 18. The outer walls of the tops of the two support plates 18 are both equipped with linear motors 19 by bolts, and the output ends of the two linear motors 19 are equipped with sliding frames 20 by bolts. A linear motor 21 is installed on the outer wall of one side of the sliding frame 20 by bolts, and a connecting frame 23 is installed on the output end of the linear motor 21 by bolts, and a linear motor 21 is installed on the outer wall of one side of the connecting frame 23 by bolts. Linear motor three 22, linear motor one 19, linear motor two 21 and linear motor three 22 all use Hiwin linear motor module LMSSA-10S200-1-1150, and the output end of linear motor three 22 is respectively installed with tin feeder 24, tin sucker 25, laser 26 and industrial camera 27 through bolts. The principle of tin sucker 25 is: the heater makes the temperature of the tin sucking head reach above 350℃ through the heating core. When the solder is melted, the vacuum gun generates negative air pressure through vacuum negative pressure to instantly suck the solder into the tin holding chamber;

[0033] The principle of laser 26 is as follows: during the welding process: feeding the board - the blocking cylinder blocks the product in place, the pressure plate cylinder presses down - the lower camera scans the code for positioning - walks to the solder joint that needs to be repaired - the desoldering device goes up to clean the solder joint - moves to the welding position - the desoldering device sends the laser to emit laser - the desoldering repair function is completed - the product flows out;

[0034] A tin breaker is also installed on one side of the tin sucker 25. The working principle of the tin breaker is to use a knife-shaped gear to press a small hole on the tin wire to improve the welding environment, so that the flux is vaporized when the soldering iron is heated and overflows from the hole, thereby enhancing the solderability and fluidity of the solder and preventing the occurrence of the "tin explosion" phenomenon;

[0035] The industrial camera 27 uses a Hikvision industrial camera, and the laser 26 uses a 100W (laser wavelength customized) laser transmitter. When detecting the solder joint position at the bottom of the PCBA board, the linear motor 19 will start, and the sliding frame 20 will slide on the support plate 18, so that the industrial camera 27 moves forward and backward. At the same time, the linear motor 21 will start, and the linear motor 21 will move the connecting frame 23 left and right. Then the linear motor 3 22 will start, and the industrial camera 27 will move up and down. This process realizes the movement of the industrial camera 27 in the three directions of XYZ, so as to facilitate the detection of solder joints at other positions on the bottom of the PCBA board;

[0036] During the inspection, when a bad point is detected, the solder sucker 25 will start, and the solder sucker 25 will suck away the tin points of the bad points. The subsequent movement of the tin feeder 24 will transfer one end of the tin wire to the position of the bad point, and then the laser 26 will start to weld the tin wire on, so as to achieve the bad point repair state, avoiding defects such as welding leakage during the production process of the PCBA board. A control box 16 is installed inside the profile frame 1 by bolts, and the control box 16 is integrated with a control circuit. According to the design of the worker, the control box 16 can control the operation of the equipment, and the control box 16 is electrically connected to the tin feeder 24, the solder sucker 25, the laser 26 and the industrial camera 27 through wires.

[0037] The present invention provides an online laser soldering machine. When a soldered PCBA board is sent into the interior of the device, through the operation of linear motor 19, linear motor 21, and linear motor 3 22, the industrial camera will move in three directions of XYZ to detect the solder joints at the bottom of the PCBA board to determine whether there are problems with the solder joints at the bottom of the PCBA board. If the industrial camera 27 detects a bad point, the tin sucker 25 will start to suck away the tin points at the bad points. Subsequently, the tin feeder 24 will move to transfer one end of the tin wire to the position of the bad point. After that, the laser 26 will start to weld the tin wire on, thereby achieving a bad point repair state and avoiding bad problems such as leaking solder during the production process of the PCBA board.

When the drive motor 33 is started, the transmission screw 34 will carry the two mounting frames 29 in The guide rod 41 slides toward each other so that the device can hold PCBA boards of different sizes. After the inspection and repair are completed, the drive motor 33 will start in reverse, and the transmission screw 34 will drive the two mounting frames 29 away from each other, so that the mounting frame 29 no longer holds the PCBA board, so that the PCBA board falls into the lower machine of the device, and the output end of the drive motor 33 is fixedly connected to one end of the transmission screw 34 through a flat key, and the guide rod 41 is externally slidably connected to two mounting frames 29, and the mounting frame 29 and the transmission screw 34 are threadedly connected, and a plurality of suction cups 40 are installed on the outer wall of one side of the bottom of the mounting frame 29 by bolts.
