An airtight cap sealing fixture based on hot plate heating

Abstract

The invention discloses an airtight cap sealing fixture based on hot plate heating. The airtight cap sealing fixture is characterized by comprising a heating plate, fixing screws, a press plate and press blocks, the press plate is pressed above the heating plate, and the press blocks are located between the heating plate and the press plate; the center of the heating plate and the center of the press plate are each provided with a screw hole; the screw holes are matched with the fixing screws. The airtight cap sealing fixture has the advantages that as circuits are arranged in grooves in the heating plate, protection for the circuits can be improved, and the damage to the circuits during use can be reduced; after a cover plate with a solder ring is placed above the heating plate in the manner of being aligned to a corresponding position, the press blocks are lightly placed onto the cover plate, and the screws are screwed; when rotated to the degree that the press blocks just make contact with the cover plate, the screws are rotated by a certain angle, a certain amount of force is applied to the screws, and then the cover plate can be fixed; the positions of the press blocks can be modified according to the requirements of products, and different style selections can be provided. The airtight cap sealing fixture is simple in structural design, quick in operation method and capable of well solving the technology problem in the cap sealing process.

Description

technical field [0001] The invention relates to an airtight sealing cap fixture, which belongs to the technical field of process production equipment. Background technique [0002] Microwave power devices are widely used in communication systems and radar systems. In the design of microwave devices, airtightness requirements are relatively high, because the quality of the sealing cap directly affects the reliability of the circuit, and then affects the service life of the circuit. The shell and cover of the circuit are separated and need to be welded together by solder, and the fixation before welding is more important. The strength and positioning of the position all determine the quality of the sealing cap. In the patent, the circuit is placed on a board with grooves, so that the lower end of the circuit is fixed, and then the cover plate is placed on the tube shell. After the two ends are placed, the pressure block is placed on it, and it is fixed by screws. After the sc...
