[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] like Figures 1 to 6 As shown, the utility model provides a PCB finished board repair device, including a base 1, and also includes:
[0025] A tin melting structure, which is arranged on the top of the base 1 and is used to melt the tin solder joints of the faulty components on the finished PCB;
[0026] An adjustment component, which is arranged on the base 1 and is used to adjust the repair point of the PCB finished board;
[0027] The tin melting structure includes a support frame 2, which is installed on the top of the base 1. A camera device 3, a display 4 and a heat insulation ring 6 are arranged on the outside of the support frame 2. A hot air gun 5 is connected to the outside of the heat insulation ring 6.
[0028] Among them, the adjustment component includes a first fixed rod 7, which is installed inside the base 1, and a tooth groove 8 is provided at the bottom of the first fixed rod 7. A movable part 9 is sleeved on the outer surface of the first fixed rod 7, and a U-shaped plate 10 is provided on the outer side of the movable part 9. A slot 11 is provided on the outer side of the U-shaped plate 10, and a mounting rod 12 is installed inside the slot 11. A return spring 13 is sleeved on the outer surface of the mounting rod 12, a clamping block 14 is installed on the inner side of the U-shaped plate 10, and a placement rack 15 is sleeved on the top of the U-shaped plate 10, and a second fixed rod 16 is installed inside the placement rack 15.
[0029] The U-shaped plate 10 is pressed by the placement rack 15, so that the U-shaped plate 10 will drive the mounting rod 12 to move downward along the top of the movable part 9, so that the U-shaped plate 10 can drive the block 14 to separate from the tooth groove 8. At this time, the movable part 9 can move along the outer surface of the first fixed rod 7. At the same time, the placement rack 15 can move forward and backward through the cooperation between the U-shaped plate 10 and the second fixed rod 16, so that the position of the PCB finished board can be adjusted, and the elastic force of the reset spring 13 can push the U-shaped plate 10 to make the placement rack 15 contact with the insulation ring 6, and then the insulation ring 6 can be used to heat the local part of the PCB finished board.
[0030] The clamping block 14 is tooth-shaped and meshes with the tooth groove 8 .
[0031] Through the cooperation between the U-shaped plate 10 and the movable part 9, when the U-shaped plate 10 moves downward, the block 14 will be separated from the tooth groove 8, so that the movable part 9 can be released from the limit, so that the movable part 9 can move along the outer surface of the first fixing rod 7.
[0032] The return spring 13 is elastically supported between the notch 11 and the movable member 9 , and when the return spring 13 presses the U-shaped plate 10 , it can drive the placement frame 15 to contact the heat insulation ring 6 .
[0033] The design of the reset spring 13 allows the U-shaped plate 10 to have good elastic reset performance. At this time, since the reset spring 13 is in a compressed state, an elastic force is applied to the U-shaped plate 10, so that the placement rack 15 can be pushed upward by the U-shaped plate 10.
[0034] The movable part 9 is sleeved with the mounting rod 12 , and the heat insulation ring 6 is located directly below the camera device 3 .
[0035] Through the cooperation between the movable part 9 and the mounting rod 12, the U-shaped plate 10 can drive the mounting rod 12 to slide up and down along the top of the movable part 9; since the insulation ring 6 is located directly below the camera device 3, it is convenient to photograph the PCB fault location through the camera device 3 and present it through the display 4 at the same time.
[0036] The U-shaped plate 10 is sleeved with the second fixing rod 16 , and the top of the placement rack 15 is used to place the finished PCB board.
[0037] Through the cooperation between the U-shaped plate 10 and the second fixing rod 16, the placement rack 15 can drive the second fixing rod 16 to move along the inside of the U-shaped plate 10, so as to control the position of the finished PCB board.
[0038] The working principle and use process of this utility model:
[0039] First, press the placement rack 15 downward and place the PCB finished board. At this time, the U-shaped plate 10 will drive the installation rod 12 to move downward along the top of the movable part 9, so that the U-shaped plate 10 can drive the block 14 to separate from the tooth groove 8. At this time, the movable part 9 can move along the outer surface of the first fixed rod 7. At the same time, through the cooperation between the U-shaped plate 10 and the second fixed rod 16, the placement rack 15 can move forward and backward, so as to adjust the position of the PCB finished board, and the elastic force of the reset spring 13 can push the U-shaped plate 10 to make the placement rack 15 contact with the insulation ring 6, and then the insulation ring 6 can be used to heat the local part of the PCB finished board.
