The second tray T2 placed on the second conveyor unit 521 of the second conveyance unit 520 is moved by the second conveyor unit 521 and transferred to the tray rotation unit 522, And transmits it to the first conveyor unit 460 provided in the low vacuum chamber 450 of the Y-direction welding apparatus 400. The second tray T2 is transferred to the first conveyor unit 460 and the second tray T2 is conveyed to the first conveyor unit 460 after the shutter of the low vacuum chamber 450 is opened in the state that the tray rotation unit 522 is rotated, And then the shutter is closed. After the shutter positioned between the high vacuum chamber 410 and the low vacuum chamber 450 is opened, the first conveyor unit 460 transfers the second tray T2 to the third stage 480, and then the shutter is closed. A pair of circular welding electrodes R3 of the first Y direction welding head 420 move downward and a welding object arranged on the second tray T2 as the third stage 480 moves in the Y direction is moved in the Y direction And seam welding is performed. Since the object to be welded is a welded package and cover, the long sides of the package and the cover are abutted. As a result, welding for sealing the inside of the object to be welded is completed. When the Y-directional line welding of all the welding objects arranged in the second tray T2 is completed, the second tray T2 is moved to the tray rotation unit 522 through the low vacuum chamber 450 again do. The second tray T2 moved to the tray rotating unit 522 is recovered by tray recovering means (not shown). The second Y-direction welding head 430 welds the welding objects arranged in the second tray T2 in the Y direction when only a part of the welding objects are arranged in the second tray T2.

As described above, according to the present invention, the X-direction welding device 300 for welding the short side (X direction) of the package and the cover to be welded, the soft soldering device 200 for contacting the package and the cover, And a Y-direction welding device 400 for welding the long sides (Y-direction) of the cover, so that the welding work for sealing the package and the cover is performed in one piece of equipment, thereby simplifying the entire manufacturing line.

In addition, since only the Y-direction welding apparatus 400 for welding the long sides of the object to be welded is located inside the high vacuum chamber 410, the size of the high vacuum chamber 410 is small and the structure for installing the vacuum chamber is simple And it costs less to maintain it. The Y-direction welding apparatus 400 is a final step of sealing the package and the cover, which are objects to be welded. The final process of the package and the cover is performed in the high vacuum chamber 410 so that the inner space of the package and the cover is vacuum- The cover is welded.

The first stage 210 and the camera 271 of the sensing unit 270 are located at the same height and the second stage 230 is positioned below the camera 271 And the second driving unit 240 not only moves the second stage 230 in the X and Y directions but also rotates the second stage 230 so that the reciprocating motion of the bucket head 257 of the component transfer unit 250 The movement distance is shortened and the configuration of the first and second stages and the sensing unit 270 becomes compact to reduce the size of the usable attaching device 200. If the first stage 210, the camera 271 and the second stage 230 are positioned at the same height, the burring head 257 is moved to the end of the second tray T2 placed on the second stage 230 (The end farther from the first stage 210) so as to cover the cover in the package located at the end. However, according to the present invention, since the cover covers the cover up to the package located at the center of the second tray T2, and then rotates the second tray T2 to cover the cover in the packages located in the other half area, 257 are shortened.
