[0002] A diode is a semiconductor device that limits the flow of current in one direction. It is widely used in electronic devices such as rectifiers, amplifiers, switches, etc. A diode is usually made of two materials: N-type (negative) and P-type (positive) semiconductor materials. During the soldering process, the leads of the diode are connected to other electronic devices to complete the circuit connection.

[0003] At present, diode welding usually requires manual loading, which has some defects that affect production efficiency and work safety. Operators need to place the diode parts under the fast welding head in a timely and accurate manner, and when the work is frequent, human factors may cause instability in loading and inaccurate placement, increasing the waste and error rate of diode parts. Most importantly, manual loading has high labor intensity and certain safety risks.

[0004] Therefore, there is an urgent need for an automatic diode welding feeding device to solve the technical defects proposed in the above-mentioned technology. Utility Model Content

[0005] The utility model aims to provide an automatic feeding device for diode welding, so as to solve the problem that manual feeding is required and the safety risk is high in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic feeding device for diode welding, comprising a feeding trough and a feeding plate, the feeding plate is installed in the feeding trough, a transmission component is arranged at the front end of the feeding trough, a moving component is arranged on the left side of the feeding trough, the moving component comprises a gear ring, the inner wall of the gear ring is processed with teeth, a fixed plate is fixed on the left side of the feeding trough, a motor seat is fixed at the bottom end of the fixed plate, a swing arm motor is installed at the motor seat, the output shaft of the swing arm motor is fixedly connected with a connecting arm, the other end of the connecting arm is movably connected with a gear, the gear meshes and rotates with the teeth on the inner wall of the gear ring, a slide groove is opened in the feeding trough, a moving seat is slidably connected in the slide groove, a hinge block is fixed on the top of the moving seat, and a swing rod is movably connected between the hinge block and the central axis of the gear.

[0007] Preferably, the top of the movable seat is fixedly connected, a welding groove is processed in the loading plate, clamping cylinders are installed on both sides of the loading plate, and a feeding cylinder is fixed on the front end of the loading plate, and the left and right sides are arranged correspondingly.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the diode welding automatic feeding device not only realizes automatic feeding, reduces the safety risk of manual material swinging, reduces the time required for transmitting diodes, arranges them neatly and orderly, and has higher feeding efficiency, but also realizes clamping positioning and auxiliary welding, thereby ensuring the stability and accuracy of the welding process;

[0015] The device is provided with gears, gear rings, swing arm motors, moving seats, and swing rods. When loading, the swing arm motor drives the connecting arm to swing, driving the gear to make a clockwise circular motion in the gear ring.

When the feeding plate is reset after feeding, the transmission motor rotates again, and the next set of diode components is pushed into the welding groove. By setting the transmission component, the length and the installation height can be set according to the size of the welding machine, which reduces the time required for transmitting the diodes, arranges them neatly and orderly, and has higher feeding efficiency.

[0017] By providing a moving seat, a clamping cylinder, a welding groove, a loading plate and a feeding cylinder, the loading plate is fixed on the moving seat and moves with the left and right movement of the moving seat. When the diode component is pushed into the welding groove, two groups of clamping cylinders quickly clamp the diode component to avoid the diode component offset when the loading plate moves and cause loading dislocation. When the loading plate moves to the bottom of the welding machine head, the clamping cylinder releases the clamping, and the feeding cylinder pushes the diode component in the welding groove a certain distance to extend the metal foot, and then the clamping cylinder clamps the diode component again to assist welding, thereby ensuring the stability and accuracy of the welding process and high welding accuracy.
