[0022] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0023] See attached Figure 1-5 As shown, the heating repair jig for PCB boards in embodiment 1 includes an electric control box 1; a heating positioning mechanism provided on the electric control box 1, which is used for positioning and heating the PCB board, and the heating positioning mechanism includes: a support plate 2 located on the electric control box 1; a connecting jig 21 fixedly connected to the support plate 2; a positioning groove 22 provided on the connecting jig 21; a plurality of heating rods 23 passing through the interior of the connecting jig 21; a vacuum positioning mechanism provided on the connecting jig 21 for fixing the PCB board; and a side pushing mechanism for preliminary positioning of the PCB board.

[0024] The PCB board can be placed in the positioning groove 22 and positioned by the side push mechanism after placement. After positioning is completed, it is fixed by the vacuum positioning mechanism. When the PCB board is fixed by the vacuum positioning mechanism, the heating rod 23 can be used to heat the connection fixture 21. When the temperature of the connection fixture 21 rises, the temperature of the PCB board can be increased, so that the solder joints on the PCB board are melted in batches, and the parts on the PCB board can be replaced in batches quickly without manual processing of the solder joints, thereby improving work efficiency. No manual intervention is required during the heating process, avoiding damage to other parts, reducing accidents caused by manual operation during the fusion welding process, and reducing manual labor intensity.

[0025] The connecting fixture 21 and the supporting plate 2 are fixed with screws, so that the connecting fixture 21 can be replaced according to different PCB boards.

[0026] Furthermore, the connecting fixture 21 is provided with a plurality of mounting grooves 24 corresponding to the positions of the heating rods 23 , and temperature sensors 25 are provided inside the mounting grooves 24 .

[0027] The installation slot 24 can make the temperature sensor 25 closer to the heating rod 23, so that the temperature perception is more accurate. The temperature sensor 25 can provide feedback on the temperature rise to avoid excessive temperature.

[0028] Furthermore, the vacuum positioning mechanism includes: a suction nozzle 26 that passes through the connecting fixture 21 and has a vacuum suction hole located in the positioning groove 22; and an air valve 27 that is in communication with the suction nozzle 26 and connected to the vacuum device inside the electric control box 1.

[0029] The vacuum device inside the electric control box 1 is used to evacuate the air, and the air enters the air valve 27 from the vacuum suction hole of the suction nozzle 26. When the PCB board is located on the vacuum suction hole, negative pressure can be used for adsorption and fixation.

[0030] Furthermore, the side push mechanism includes: a movable groove 3 connected to the positioning groove 22; an insert 31 fixed in the movable groove 3; an extrusion member 32 capable of moving between the insert 31 and the movable groove 3 and toward the positioning groove 22; and a return spring 33 provided on the other end of the insert 31 and fixedly connected to the extrusion member 32, and the return spring 33 can push the extrusion member 32 to squeeze the PCB board placed in the positioning groove 22.

[0031] When the PCB is placed in the positioning groove 22 , the elastic deformation of the return spring 33 causes the extrusion member 32 to press the PCB, thereby pressing the PCB against the positioning groove 22 , thereby achieving preliminary fixation of the PCB.

[0032] Furthermore, the extrusion member 32 is provided with an extrusion block 34 extending to the positioning groove 22 .

[0033] The extrusion block 34 can realize multi-point positioning of the PCB board and increase the stability of positioning.

[0034] Furthermore, the extrusion member 32 is provided with a push rod 35 extending to the outside of the movable groove 3, and the movable groove 3 is provided with a closing cover 36 for closing. The closing cover 36 is provided with a notch that allows the push rod 35 to move. The notch allows the push rod 35 to move even when the closing cover 36 closes the movable groove 3.

[0035] The push rod 35 makes it convenient for the operator to pull the extrusion piece 32, so as to facilitate the placement of the PCB board in the positioning groove 22, and prevent the extrusion piece 32 from blocking the positioning groove 22, making it difficult to place the PCB board. The closing cover 36 can close the top to prevent dust from falling and affecting the maintenance of the PCB board.

[0036] Furthermore, the electric control box 1 is provided with a control panel 11 , buttons 12 , and a buzzer 13 , and the electric control box 1 is internally provided with a PLC control program that can be linked therewith.

[0037] The control panel 11, button 12 and buzzer 13 can be linked through the PLC control program, and then the temperature controller and the heating rod 23 can be connected, so that the button 12 can be used to control the power on and off, or the opening of different heating rods 23 can be controlled separately. The buzzer 13 can alarm when the high temperature threshold is reached to avoid damage to the PCB board caused by high temperature. The control panel 11 can accurately fill in the preset temperature and display the data.

[0038] Furthermore, a handle 28 is provided on the support plate 2, which facilitates the operator to pick up the support plate 2 and then replace the support plate 2 with one with a different heating positioning mechanism on the electric control console.

[0039] Furthermore, a support base 29 is provided on the electric control box 1. The support base 29 can increase the height of the support plate 2. Raising the height of the support plate 2 can prevent high temperature from affecting the electric control box 1 and play an isolation role.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
