By driving the right screw rod 5-507 and the left screw rod 5-505 to rotate simultaneously by the horizontal motor 5-501, since the thread directions of the left and right screw rods 5-505 and 5-507 are opposite, the lower left and right templates 5-301 and 5-401 can move towards or away from each other.

[0072] Working principle of the forming mold 5:

[0073] First, the lifting motor 5-1901 operates, driving the movable plate 5-1907 upward through the lead screw 5-1905. The movable plate 5-1907 pushes the left and right shoulder height adjusting plates 5-303 and 5-403 to extend out of the top surfaces of the left and right lower die forming plates 5-302 and 5-402 to the required height. Then, the horizontal motor 5-501 operates, driving the right screw 5-505 and the left screw 5-507 to rotate simultaneously, thereby driving the left and right lower die forming plates 5-302 and 5-402 and the left and right upper die forming plates 5-804 and 5-904 to approach each other to the required distance. At this time, the flat package device to be processed (which mainly includes a chip carrier in the middle and external pins) is placed between the left and right shoulder height adjusting plates 5-303 and 5-403. Specifically, the chip carrier is located between the inner side walls of the left and right shoulder height adjusting plates 5-303 and 5-403, and the pins are placed on the top surfaces of the left and right shoulder height adjusting plates 5-303 and 5-403. Finally, the linear cylinder 5-7 drives the upper left die 5-8 and the upper right die 5-9 to move downward simultaneously through the cross connecting plate 5-6. When the upper left and right die forming plates 5-804 and 5-904 are docked with the left and right shoulder height adjusting plates 5-303 and 5-403, the pins are pressed between the upper left and right die forming plates 5-804 and 5-904 and the left and right shoulder height adjusting plates 5-303 and 5-403. The upper left die 5-8 and the upper right die 5-9 continue to move downward, and the upper left and right die forming plates 5-804 and 5-904 push the spring mounting plate 5-15 upward, and the spring 5-16 is compressed until the bottom surfaces of the left and right pressing plates 5-805 and 5-905 contact the corresponding forming surfaces 5-12. The upper left die 5-8 and the upper right die 5-9 continue to move downward, causing the upper left and right die mounting plates 5-803 and 5-903 to move downward a certain distance, cutting off the excess portions of the outer ends of the pins, and the cut-off materials fall into the corresponding material receiving grooves. Then, pause for a few seconds. After the pins are completely formed, the linear cylinder 5-7 drives the upper left die 5-8 and the upper right die 5-9 to move upward and reset through the cross connecting plate 5-6

[0079] The working principle of the positioning mechanism 6: By driving the intermediate plate 6-2 to rotate through the adjusting handle 6-15, and then driving the four movable blocks 6-9 to move through the limiting posts 6-11. Under the combined action of the first limiting groove 6-6 and the second limiting groove 6-8, the four positioning plates 6-12 can form rectangular positioning frames of different sizes, so as to adapt to flat packaging devices of different specifications.

[0080] First, visually estimate the size of the flat-packaged device, adjust the rectangular positioning frame to a size slightly larger than the flat-packaged device, then place the flat-packaged device on the rectangular positioning frame, and then rotate the intermediate plate 6-2 so that the rectangular positioning frame perfectly matches the flat-packaged device. Finally, tighten the locking screw 6-16 to lock and position the intermediate plate 6-2.

[0081] See Figures 22 to 29 As shown, the picking mechanism 7 includes an X-direction guiding block 7-1, an X-direction sliding block 7-2, an L-shaped seat 7-3, a connecting plate 7-4, and a handle 7-5.

A first limiting column is provided at the bottom of the handle 7-5, and the first limiting column is fitted in the limiting groove 7-15. The handle 7-5 is detachably connected to the handle seat 7-14.

[0083] In this embodiment, a limiting plate 7-16 is detachably installed on the connecting bracket 7-10. A second limiting column 7-17 is provided on the bottom surface of the limiting plate 7-16. A limiting hole 7-18 is provided on the top surface of the X-direction guiding block 7-1, and the second limiting column 7-17 is fitted in the limiting hole 7-18. Three limiting holes 18 are provided on the top surface of the X-direction guiding block 7-1, so as to conveniently position the suction nozzle 7-12 to three specified positions, that is, the initial position, the device picking position, and the device placing position. The device picking position corresponds to the rectangular positioning frame on the positioning mechanism 6, and the device placing position corresponds to the central position between the left and right shoulder height adjusting plates 5-303 and 5-403 on the forming die 5.

[0084] In this embodiment, a micro switch 7-19 is installed on the X-direction guiding block 7-1 corresponding to the limiting hole 7-18. The position of the suction nozzle is further accurately confirmed through the micro switch 7-19.

A control button 7-27 is installed on the handle 7-5 for controlling the opening or closing of the suction nozzle 7-12.

[0089] In use, the flat package device is placed on the rectangular positioning frame of the positioning mechanism 6. Press down the handle 7-5, so that the connecting plate 7-4 rotates around the rotating shaft 7-6, and the other end of the connecting plate 7-4 lifts upward. Through the cooperation of the pin 7-13 and the long circular hole 7-7 on the connecting plate 7-4, the bracket 7-10 is driven to move upward in the vertical direction. The Y-direction slider 7-9 plays a guiding role. At the same time, the limiting plate 7-16 moves upward, so that the second limiting column 7-17 moves out of the limiting hole 7-18. Then, push the L seat 7-3 forward along the X-direction guide block 7-1 through the handle 7-5. When it moves to the position for sucking the device, put down the handle 7-5, and the connecting bracket 7-10 moves downward. The second limiting column 7-17 is inserted into the limiting hole 7-18. At the same time, the bottom surface of the limiting plate 7-16 touches the micro switch 7-19, and the suction nozzle 7-12 is controlled to work through the control button 7-27 on the handle 7-5, and the device is sucked up; press down the handle 7-5 again, and the connecting bracket 7-10 drives the limiting plate 7-16 to move upward, and the second limiting column 7-17 moves out of the limiting hole 7-18; continue to push the L seat 7-3 forward along the X-direction guide block 7-1 through the handle 7-5. When it moves to the position for placing the device, put down the handle 7-5, and the connecting bracket 7-10 moves downward. The second limiting column 7-17 is inserted into the limiting hole 7-18. At the same time, the bottom surface of the limiting plate 7-16 touches the micro switch 7-19, and the suction nozzle 7-12 is controlled to close through the control button 7-27 on the handle 7-5. The device loses the suction of the suction nozzle and drops to the position for placing the device. Then, the forming die 5 works to form the pins of the flat package device. After the forming is completed, the flat package device is taken out by the picking mechanism 7 and placed on the rectangular positioning frame of the positioning mechanism 6. The flat package device is manually rotated 90° and then placed on the rectangular positioning frame again. Repeating the above operations can complete the forming of the pins around the flat package device.
