Description

Technical Field

[0002] A magnetron is a device used to generate microwave energy. A filter component is an important part of the magnetron, mainly including a feedthrough capacitor and a choke coil. During the production process, two choke coils need to be placed in opposite directions and symmetrically welded to the two terminals of the feedthrough capacitor. Patent No. ZL 202220168665.3 discloses a capacitor component transportation tray and a capacitor welding machine. The capacitor welding machine includes a transportation tray, a solder device, and a transportation device. The transportation tray includes a base provided with a groove body. The groove body includes a first groove body for placing a plug and restricting the movement of the plug, and two second groove bodies for respectively placing a choke coil and restricting the movement of the choke coil placed therein.

The vertical plate 22 is vertically arranged in the middle position, presenting a vertical facade structure. The socket and the end seat are respectively vertically connected to both sides of the vertical plate 22.

The coil gripper 4 is connected to the telescopic end of the coil lifting mechanism. The inner side of the core 25 gripper is in an arc structure and can be in close contact with the outer side of the core 25 to generate a large clamping force, which is beneficial to improving the clamping stability. When the coil gripper 4 is located above the fixed seat 2, the position of the coil gripper 4 corresponds to that of the core 25, and it can be directly above the core 25.

[0048] The capacitor pressing block 6 and the capacitor gripper 3 correspond to the positions of the feedthrough capacitor 21 and the choke coil 24 respectively. The capacitor pressing block 6 is provided with a pressing block cavity for accommodating the feedthrough capacitor 21, and the pressing block cavity matches the outer contour of the feedthrough capacitor 21. The mounting plate 7 is located between the capacitor pressing block 6 and the coil lifting mechanism. The upper side of the mounting plate 7 is connected to the output end of the coil lifting mechanism, and the lower side of the mounting plate 7 is connected to the capacitor pressing block 6 and the coil gripper 4. The capacitor pressing block 6 and the mounting plate 7 slide up and down in the vertical direction. The elastic resetting member 8 is located between the capacitor pressing block 6 and the mounting plate 7. The elastic resetting member 8 can be a spring. The two ends of the elastic resetting member 8 are respectively abutted against the capacitor pressing block 6 and the mounting plate 7 to provide a sliding reset function. Driven by the coil lifting mechanism, the mounting plate 7 moves downward. First, the capacitor pressing block 6 covers the feedthrough capacitor 21 located on the fixed seat 2, so as to realize the pre-pressing and limiting of the feedthrough capacitor 21. Then, the capacitor gripper 3 places the choke coil 24 in the fixed seat 2, and the terminal 23 of the capacitor pressing block 6 is lapped with the pin 26 of the choke coil 24, improving the assembly accuracy. During this period, as the sliding distance between the capacitor pressing block 6 and the mounting plate 7 decreases, the elastic resetting member 8 is compressed, and its compression force is converted into the covering force on the feedthrough capacitor 21, improving the covering stability.
