For example, the Chinese invention patent with patent number: 201711324622X discloses a fast soldering device, including a support table and a conveyor belt. A regulator is arranged in front of the support table, a top seat is arranged on the support table, a track is arranged inside the top seat, a DC power supply is installed on the track, a lower magnet is arranged above the DC power supply, an operating table is arranged inside the top seat, an upper magnet is arranged inside the operating table, a top column is arranged on one side of the support table, an insulating belt is arranged on the top column, a conveyor belt is arranged on the insulating belt, an insulating belt is arranged at the rear of the conveyor belt, a welding gun is arranged under the conveyor belt, and a temperature sensor is arranged next to the welding gun; the machine replaces manual labor, improves efficiency and protects human health;

[0003] Through research on the above-mentioned soldering device, it is found that its welding freedom is poor, and it cannot realize fully automatic circular welding. The soldering head cannot solder 360° without dead angles on the spherical surface. Therefore, we urgently need to invent a circular fully automatic soldering device that can solder 360° without dead angles on the spherical surface to solve the above-mentioned technical problems. Summary of the invention

[0004] In view of the above problems, the present invention provides an adjustable circular fully-automatic soldering device, which realizes two-dimensional rotational freedom through a rotating motor and a connecting rod driving motor, and the position length of the solder head is adjustable, thereby determining the circumferential diameter when rotating the solder. The solder head can solder 360° on the spherical surface without dead angles, thereby realizing the circular fully-automatic soldering function; its connecting rod mechanism is a double parallelogram structure, and the connecting rods are rotatably hinged with each other, thereby increasing the range of motion and freedom of the solder head and improving work efficiency.

[0005] The technical solution used in the present invention is: an adjustable circumferential fully automatic soldering device, comprising: a rotating motor, a rotating support arm, a connecting rod driving motor, a connecting rod mechanism, a fixing seat, an electric telescopic rod, a soldering head, a tin bar clamping and feeding mechanism and a control device;

[0006] The rotating motor is fixedly mounted on the mechanical arm of the six-axis robot through a motor seat, and its motor shaft is connected to the rotating support arm to drive the rotating support arm to rotate; one end of the connecting rod mechanism is hinged on the rotating support arm, and the other end is hinged to the fixed seat, and the connecting rod drive motor is installed on the side of the rotating support arm, and its motor shaft is connected to one end of the connecting rod mechanism through a coupling to drive the connecting rod mechanism to make a circular motion;

[0007] The electric telescopic rod is fixedly mounted on the fixed seat, and its extension rod is connected to the solder head to adjust the position and length of the solder head; the tin bar clamping and feeding mechanism is also mounted on the fixed seat, and the tin bar is transported to the solder head through the tin bar clamping and feeding mechanism to cooperate with the solder head to complete the soldering work;

[0008] The connecting rod mechanism is a double parallelogram structure, and the connecting rods are rotatably hinged with each other. The control device controls the connecting rod drive motor to start, and then drives the solder head and the tin bar clamping and feeding mechanism to perform circular welding on the vertical surface through the connecting rod mechanism. The rotating motor is started to drive the entire device to perform circular welding on the horizontal surface. The two cooperate with each other to achieve that the solder head can perform soldering at 360° without dead angles on the spherical surface.

[0009] Furthermore, the rotating motor and the connecting rod driving motor are both stepping motors.

[0010] Furthermore, the tin bar clamping and feeding mechanism realizes automatic feeding of the tin bar through a feeding motor.

[0011] Furthermore, the rotating motor, the connecting rod driving motor and the electric telescopic rod are all electrically connected to the control device, and the control device is controlled by PLC.

[0012] Since the present invention adopts the above technical solution, the present invention has the following advantages:

[0013] (1) The present invention realizes two-dimensional rotational freedom through a rotating motor and a connecting rod driving motor, and the position length of the soldering head is adjustable, thereby determining the circumferential diameter when rotating the soldering head.
