Then, the horizontal lock feeding motor 2-9 drives the vertical lock feeder 2-4 to move through the vertical connecting table 2-3. Simultaneously, the vertical lock feeder 2-4 lifts the vertical lock feeding block 2-7, allowing the lock to enter the assembly station, that is, to move the lock to the edge of the lunch box lid, so that the hook is located in the position of the constriction rotation groove on the lunch box lid; then, as... Figure 5-7The locking die 5 is press-fitted. First, the main pressing motor 5-5 causes the main slider 5-7, the auxiliary slider 5-9, the adapter 5-11, and the pressing block 5-12 to move downwards as a whole until the pressing groove in the pressing block 5-12 is pressed against the upper edge of the hook 8-2.

Then, driven by auxiliary pressing motor 5-6, the adapter block 5-10, adapter seat 5-11, and pressing block 5-12 move downwards as a whole, thus pressing the latch hook 8-2 and engaging it onto the lunchbox lid's locking shaft. This completes one pressing and securing step. After pressing and securing, as shown... Figure 8 and Figure 9 First, the lunchbox lid feeding motor 4-7 moves upward, lifting the lunchbox lid from the current workstation's lunchbox lid tray 7-2. Then, the lunchbox lid rotating cylinder 4-9 rotates the lunchbox lid rotating disk 4-10, causing the lunchbox lid to rotate. After rotation, the lunchbox lid is moved to the next workstation, the next lunchbox lid tray 7-2, by the horizontal movement motor 4-3 for pressing. After placement, the lunchbox lid fixing suction cup 4-11 releases, and the entire lunchbox lid feeding support plate 4-4 is moved by the horizontal movement motor. Driven by motor 4-3, the lid returns to its original position and is then driven again by motor 4-7 to press the lid of the lunch box on the current workstation onto the lid tray 7-2. Since the lids are often not square, different lengths of latches are needed to combine them at different positions. Simultaneously, the lid feeding suction cup 4-13 can lift the lids on the preparation table and place them onto the lid tray 7-2 at the first workstation.
