Description

Technical Field

[0001] The present invention relates to a parallel seam welder, and particularly to a parallel welding packaging tray used in a parallel seam welder, which can realize reliable and stable positioning of each shell in the tray. Background Art

[0002] A parallel seam welder is a seam welding device that welds and assembles a shell and a cover plate together by resistance welding in a nitrogen or vacuum environment; chip packaging has strict requirements for the atmosphere environment. The chip is placed in a box-shaped shell, and after covering the cover plate, packaging is carried out to form a relevant electronic device module. Since the annular seal between the box-shaped shell and the cover plate is rectangular, and the seal welds are two groups of parallel seam welding edges, the parallel seam welder mainly adopts the parallel seam welding process to respectively carry out packaging welding on the two parallel sides of the rectangular seal ring of the box-shaped shell. The parallel seam welding process has the advantages of small temperature rise during seam welding and high airtightness of the seam welding. The parallel seam welding process has high reliability and is mostly used for the packaging of electronic chips such as aerospace, aviation, and military. The existing fully automatic parallel seam welder is composed of an oven, a robotic arm transmission mechanism, a spot welding and seam welding mechanism, a parallel seam welding mechanism, and an exchange box. The spot welding and seam welding mechanism and the parallel seam welding mechanism are composed of an identification system, a spot welding mechanism, a seam welding mechanism, and an X-direction moving platform. In a closed nitrogen environment, the shells and cover plates are orderly placed in a tooling box, and the tooling box is placed on the X-direction moving platform. The identification system identifies each shell and cover plate with a chip placed thereon on the tooling box, accurately places the cover plate on the seal ring of the shell through a suction nozzle, the spot welding mechanism presses two parallel electrode wheels onto the two parallel seam welding edges of the seal ring on the cover plate for spot welding. After passing the inspection, the seam welding mechanism then performs parallel seam welding to obtain the relevant electronic device module after seam welding.

[0003] The sealing mechanism in the parallel sealing welding machine is composed of a double welding head mechanism and a welding table mechanism. The double welding head mechanism is set on a gantry, which can move along the left and right Y direction and the up and down Z direction. The welding table mechanism can move along the front and back X direction and has an R rotation mechanism, which can realize that after one set of parallel welding edges is completed, it can be rotated to another set of parallel welding edges for sealing welding; on the X and R mechanisms of the welding table, a tooling box containing tube shells and cover plates is placed, and two electrode wheels are symmetrically installed on the double welding head mechanism. The two parallel electrode wheels are pressed down onto the tube shell cover plate on the welding station in the tooling box, and the welding circuit is connected. Through, resistance welding is implemented; in this process, the tooling material box moves along the front and back X direction with the welding table, and the two parallel electrode wheels roll along the X direction on the cover tube shell, completing the welding of two parallel welds during rolling; in the fully automatic sealing and welding machine, the tube shell and cover plate are placed on the parallel welding packaging tray, and the tray is transported to the parallel sealing and welding station by the robotic arm transmission mechanism. In each tray, the tube shell and cover plate are placed in the tray in different areas. On the left side of the tray, the tube shell is arranged in an array, and on the right side of the tray, the cover plate is arranged in an array; packaging During the process, the robot arm controls the suction nozzle to suck up the cover plate, and after moving it to the top of the tube shell, the cover plate is accurately placed on the sealing ring of the corresponding tube shell. This partitioned arrangement of the tube shell and the cover plate in the material tray has the disadvantage that the suction nozzle has a long travel distance after sucking the cover plate and moving it to the sealing ring of the corresponding tube shell, resulting in a slow production rhythm. In addition, the existing material tray is provided with tube shell placement grooves in an array, and the tube shell placement grooves are arranged according to the maximum size of the tube shell processing. Since there is a certain tolerance in the machining of the tube shell, the tube shells placed in the same column in the material tray have a certain tolerance. The sizes are not completely consistent, resulting in some tube shells not being able to fit completely into the grooves where they are placed, and there will be a gap between the two; when the cover is placed on the tube shell and the parallel sealing head is pressed down, it is easy for the tube shell to slide in the gap of the groove or even warp up, which directly leads to the occurrence of sparks, destroying the airtightness of the packaged chip, and thus increasing the scrap rate of the packaged products; how to firmly fix the tube shells in the tray so that they are fixed in position during the packaging process and do not move is a difficult problem that needs to be solved in the fully automatic parallel sealing process. Summary of the Invention
