Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to a circle soldering machine. Background Art

[0002] Motor welding coils are a process in motor production. The coils of motor armature welding coils are actually a kind of varistor, which is a voltage-limiting protection device. Using the nonlinear characteristics of the varistor, when overvoltage appears between the two poles of the varistor, the varistor can clamp the voltage to a relatively fixed voltage value, thereby protecting the subsequent circuit. When the motor is opening and closing and rotating at high speed, sparks will be generated between its commutator and brush. The generation of sparks will reduce the working life of the motor and produce serious electromagnetic interference, which is a major safety hazard for working in a flammable and explosive gas environment. In order to absorb sparks, eliminate noise interference and improve safety performance, resistor and capacitor components or varistors must be installed on the motor for protection.

[0003] Most of the welding of varistors relies on manually putting the varistor ring on the shaft of the rotor, then placing the rotor on a fixture for positioning, and then relying on an automatic soldering device to weld the varistor to the end of the motor rotor. Therefore, the varistor ring and the rotor need to be aligned and sleeved when each rotor is welded. The manual placement method has low processing efficiency for the assembly line production of the rotor, and the existing welding mechanism needs to rotate a certain angle and perform multiple welding during welding to ensure that the varistor ring and the rotor are firmly connected, which not only causes a slow welding speed, but also easily leads to a waste of tin. Summary of the invention

[0004] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide a coil soldering machine, in which the rack is pushed to move by the end of the cylinder one, so that the rack can drive the gear to rotate, thereby driving the rotating shaft two and the telescopic rod to rotate, and the end of the telescopic rod can drive the sliding seat to slide along the limiting groove of the L-shaped cylinder, and the sliding seat can drive the two half-rings and the varistor ring to be connected, so that the varistor ring can be embedded in the rubber ring on the inner wall of the half-ring, and the pressure sensor arranged in the half-ring can detect whether the half-ring is connected to the varistor ring, and then the sliding seat is driven to slide to the expansion mask at the bottom end of the L-shaped cylinder by the reverse rotation of the rotating shaft two. The position of the two half rings, when they slide into the expansion housing, can be squeezed away from each other by the squeezing spring, so that the clamped varistor ring can be released, so that the varistor ring can fall onto the shaft rod of the rotor, thereby replacing the manual placement of the ring on the rotor shaft, thereby reducing labor and improving the production efficiency of the rotor; the rotor in the conveying shell can be pushed up by the lifting seat, so that the rotor can first be connected with the sliding cylinder, and the varistor ring on the rotor can be squeezed and positioned by the three fan-shaped plates at the top of the sliding cylinder, and then the rotor and the sliding cylinder can continue to rise by the second cylinder, and the three sliding blocks can resist The corresponding baffle plate is moved up, and then the discharge port on the outer wall of the tin material shell can be connected with the docking hole on the sliding block, so that the tin ball can slide out from the discharge port, and the tin ball sliding out of the discharge port will be blocked by the inner hollow cylinder, so only a single tin ball can fall into the docking hole each time, and then the lifting seat is driven down by cylinder 2, so that the tin ball can slide from the sliding block to the welding part, and then the mold frame is driven down by cylinder 3, so that the three soldering irons can be driven down, so that the soldering irons can pass through the round hole and contact the tin ball, thereby melting the tin ball, so that the connection between the varistor ring and the rotor can be soldered, and at the same time, cold air can be supplied to the cavity ring through the cold air blower. Then, three air outlets at the bottom of the inner hollow cylinder are used to spray cold air through three air outlets. This can make the melted tin liquid solidify quickly, thereby increasing the welding speed. After welding is completed, the rotor is driven to continue to descend through cylinder 2, and then the connecting frame is driven to move through cylinder 4. The grab rings can be driven to rotate through two electric rods, so that the two grab rings can grab and release the welded rotor, so that the rotor can slide from the inclined slide into the collection box. The welding mechanism can simultaneously perform multiple welding between the rotor and the varistor ring, thereby increasing the welding speed. The use of tin ball welding saves tin and ensures the firmness of the welding.
