Description

Technical Field

[0001] The utility model relates to the technical field of motor processing devices, in particular to a stator core PCB welding system. Background Art

[0002] A servo motor is an engine that controls the operation of mechanical components in a servo system. It is an auxiliary motor indirect speed change device. It can convert voltage signals into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. It has the characteristics of small electromechanical time constant, high linearity, and starting voltage. Its working principle can be simply summarized as: input control signal → servo controller → servo motor → output motion. The servo system consists of a servo motor, a servo controller, and a feedback device. When the servo motor receives a pulse signal, it will rotate an angle corresponding to a pulse to achieve displacement.

[0003] The structure of a servo motor is mainly composed of stators, rotors, encoders and other components. The stator of a servo motor is usually made of laminated silicon steel sheets, and two-phase or three-phase windings are embedded in the surface slots. These windings are used to generate a rotating magnetic field. The rotor is the rotating part of the servo motor, and its structure is related to the type of motor. For permanent magnet servo motors, the rotor is usually composed of permanent magnets, which rotate in the magnetic field generated by the stator.

[0004] Servo motors are widely used in many fields, such as industrial automation, electronic equipment, transportation, printing and packaging, and robots, etc. They have the advantages of high precision, high speed, strong adaptability, good stability, short dynamic response time, and good comfort. However, in the production process of servo motors, the coils of the stator core need to be connected in series and parallel to maximize the performance of the motor. The existing technology is to connect the motor coils in series and parallel through the built-in circuit of the PCB board, that is, the stator core needs to be installed with PCB first, and then the stator wire pins are connected by tin welding.

[0005] The tin soldering process generally involves dipping and drying the flux, and then soldering the stator core and PCB board assembled together. In order to achieve the above assembly process, manual operation is often used in the prior art, which is not only inefficient, but also cannot ensure the welding accuracy between the PCB board and the stator core, which seriously restricts the production efficiency of the motor and also poses safety issues.

[0006] Therefore, a new technical solution is urgently needed to solve the above technical problems. Utility Model Content

[0010] Furthermore, the flux supply mechanism, the preheating mechanism, the tin furnace and the cooling mechanism are sequentially arranged on the same side of the transverse rotation welding mechanism.

[0011] Furthermore, heat insulation plates are respectively arranged between the flux supply mechanism, the preheating mechanism, the tin furnace and the cooling mechanism.

[0012] Furthermore, the soldering flux supply mechanism is a container filled with soldering flux.

[0013] Furthermore, the preheating mechanism includes a preheating bracket fixedly connected to the table plate, and a preheating platform is arranged on the preheating bracket.

[0016] Furthermore, the cooling mechanism comprises a nozzle bracket connected to the table, and the nozzle bracket is connected to an air nozzle.

[0017] Furthermore, an electrical control component is provided in the cabinet for controlling the transverse rotation welding mechanism, the flux supply mechanism, the preheating mechanism, the tin furnace and the cooling mechanism.

[0018] Beneficial Effects
