[0032] When the device is used, the circuit board above the external conveyor belt (not shown) is first clamped by the robot arm 2 and moved to be placed above the placement plate 3, and then the drive motor 406 is turned on. The drive motor 406 drives the screw rod 401 to rotate, and then drives the movable block 403 to rotate. Through the coordinated use of the sliders 404 on both sides, the movable plate 405 is moved along the guide direction of the two sets of fixed rods 402, and then the circuit board is effectively fixed between the movable plate 405 and the fixed plate 407 through the fixed plate 407, thereby effectively avoiding the situation where the circuit board moves itself during the patch soldering and causes welding misalignment.

Two groups of sliding rods 1004 are fixedly connected, and the two groups of sliding rods 1004 are symmetrically distributed on the opposite sides of the threaded rod 1003. The outer surfaces of the threaded rods 1003 on both sides are threadedly connected with movable plates 1005. The movable plates 1005 on both sides are slidably connected to the two groups of sliding rods 1004. The opposite sides of the outer surfaces of the movable plates 1005 are rotatably connected with connecting rods 1006.

The top of the articulated frame 1007 is fixedly connected to the bottom of the placement plate 3. The opposite sides of the top of the load-bearing plate 1 are also fixedly connected with fixed frames 1008. The interiors of the fixed frames 1008 on both sides are rotatably connected with rotating frames 1009. The side of the rotating frame 1009 away from the fixed frame 1008 is rotatably connected to the connecting rod 1006.

[0036] After the welding condition of the circuit board is effectively judged, the threaded rod 1003 is driven to rotate through the output end of the double-headed motor 1002, and then the movable plate 1005 is moved through the guidance of the two sets of sliding rods 1004, and the movable plate 1005 drives the connecting rod 1006 to rotate, so that the rotating frame 1009 rotates, and then the placement plate 3 rotates, and the two output ends of the double-headed motor 1002 can be driven separately on one side, or can be driven synchronously on both sides. Therefore, by controlling the two output ends of the double-headed motor 1002 for driving, the placement plate 3 can be tilted to the front side or to the rear side, so that the qualified circuit board can slide through the inclined plate 11 to the top of the conveyor belt 1 12 or the unqualified circuit board can slide through the inclined plate 11 to the top of the conveyor belt 2 13, so as to realize the classification of whether the circuit board welding is qualified, which not only improves the efficiency of circuit board welding, but also optimizes the welding steps, thereby increasing the practicality and applicability of the device.

[0037] The working principle and use process of this device are as follows: when using this device, firstly, the circuit board above the external conveyor belt (not shown) is clamped by the robot arm 2 and moved to be placed above the placement plate 3, and then the drive motor 406 is turned on, and the drive motor 406 drives the screw rod 401 to rotate, and then drives the movable block 403 to rotate, and through the coordinated use of the sliders 404 on both sides, the movable plate 1 405 is moved along the guide direction of the two sets of fixed rods 402, and then the circuit board is effectively fixed between the movable plate 1 405 and the fixed plate 1 407 through the fixed plate 1, thereby effectively avoiding the situation where the circuit board is misaligned due to its own movement during the patch soldering.

[0038] After the circuit board is effectively fixed above the placement plate 3, the welding head 9 can be moved to the position to be welded on the circuit board through the X, Y and Z axis directions through the first drive rail 6, the second drive rail 7 and the third drive rail 8, and then the designated position of the circuit board is welded by the welding head 9. When the welding of the circuit board is completed, the welding effect can be observed through the camera 15, and then the staff can remotely check whether the welding is qualified through the information transmitted by the camera 15.

[0039] After the welding condition of the circuit board is effectively judged, the threaded rod 1003 is driven to rotate through the output end of the double-headed motor 1002, and then the movable plate 1005 is moved through the guidance of the two sets of sliding rods 1004, and the movable plate 1005 drives the connecting rod 1006 to rotate, so that the rotating frame 1009 rotates, and then the placement plate 3 rotates, and the two output ends of the double-headed motor 1002 can be driven separately on one side, or can be driven synchronously on both sides. Therefore, by controlling the two output ends of the double-headed motor 1002 for driving, the placement plate 3 can be tilted to the front side or to the rear side, so that the qualified circuit board can slide through the inclined plate 11 to the top of the conveyor belt 1 12 or the unqualified circuit board can slide through the inclined plate 11 to the top of the conveyor belt 2 13, so as to realize the classification of whether the circuit board welding is qualified, which not only improves the efficiency of circuit board welding, but also optimizes the welding steps, thereby increasing the practicality and applicability of the device.
