[0037] Refer to Figure 5 , Figure 6 and Figure 10 , the rotating assembly includes a vertical plate 27, a rotating shaft 28, a spur gear 29, a rack 30, a one-hole plate 31, a mounting block 33 and a sliding shaft 34. Vertical plates 27 are bolted to the front and rear sides of the top of the left guide rail 16. Rotating shafts 28 are rotatably connected to the middle of the upper parts of the vertical plates 27. Spur gears 29 are key-connected to the left ends of the rotating shafts 28. Racks 30 are bolted to the front and rear sides of the sliding frame 9. The racks 30 will mesh with the spur gears 29 during the downward movement. One-hole plates 31 are connected to the right ends of the rotating shafts 28. U-shaped openings 32 are opened in the upper parts of the vertical plates 27. Mounting blocks 33 are bolted to the left sides of the tops of the sliding plates 18. Sliding shafts 34 are rotatably connected to the upper parts of the mounting blocks 33. The sliding shafts 34 are located within the one-hole plates 31 and the U-shaped openings 32.

[0038] Initially, the feeding track 26 is filled with screws. The tightening block 23 is sleeved on the screw, and the magnet 24 attracts the screw. The staff places the electric baking pan on the placing plate 13. The conveyor 14 conveys the electric baking pan to directly below the electric suction cup 12. Then, multiple heat insulation plates are stacked in the storage frame 3. Next, the output shaft of the first motor 5 is controlled to rotate, driving the rotating frame 4 to rotate through the gear. The rotating frame 4 drives the sliding frame 9 to rotate, and the sliding frame 9 drives the electric suction cup 12 to rotate, turning the electric suction cup 12 to directly above the storage frame 3. Then, the output shaft of the second motor 7 is controlled to rotate, driving the lead screw 6 to rotate through the gearbox 8. The lead screw 6 drives the sliding frame 9 to move downward, and the sliding frame 9 drives the electric suction cup 12 to move downward, moving the electric suction cup 12 into the storage frame 3. The electric suction cup 12 contacts the topmost heat insulation plate in the storage frame 3 and attracts it. The first spring 10 will be compressed. The compressed first spring 10 can provide a downward thrust for the electric suction cup 12, enabling the electric suction cup 12 to be in close contact with the heat insulation plate, ensuring that the electric suction cup 12 can firmly attract the heat insulation plate. Subsequently, the output shaft of the second motor 7 is controlled to rotate in the reverse direction, driving the lead screw 6 to rotate in the reverse direction through the gearbox 8. The lead screw 6 drives the sliding frame 9 to move upward, and the sliding frame 9 drives the electric suction cup 12 to move upward. The electric suction cup 12 drives the heat insulation plate to move upward, taking the heat insulation plate out of the storage frame 3. Then, the output shaft of the first motor 5 is controlled to rotate, driving the rotating frame 4 to rotate through the gear. The rotating frame 4 drives the sliding frame 9 to rotate, and the sliding frame 9 drives the electric suction cup 12 to rotate, turning the electric suction cup 12 to directly above the electric baking pan. Then, the output shaft of the second motor 7 is controlled to rotate, driving the lead screw 6 to rotate through the gearbox 8. The lead screw 6 drives the sliding frame 9 and the sliding frame 91 to move downward. The sliding frame 91 drives the electric suction cup 12 to move downward. The electric suction cup 12 drives the heat insulation plate to move downward, installing the heat insulation plate on the electric baking pan for assembly. At this time, the bottom of the sliding frame 91 contacts the top of the connecting frame 2, and the sliding frame 91 stops moving downward. The electric suction cup 12 also stops moving downward. The sliding frame 9 continues to move downward, and the first spring 10 is compressed. The sliding frame 9 drives the straight rack 30 to move downward. During the downward movement of the straight rack 30, it will engage with the straight gear 29 and drive the straight gear 29 to rotate. The straight gear 29 drives the rotating shaft 28 to rotate, and the rotating shaft 28 drives the one-hole plate 31 to rotate. The one-hole plate 31 drives the sliding shaft 34 to move. The sliding shaft 34 slides along the U-shaped opening 32. The sliding shaft 34 first moves upward, then moves towards the electric baking pan, and finally moves downward. When the sliding shaft 34 moves upward, it will drive the sliding plate 18, the tightening block 23, and the magnet 24 to move upward. The magnet 24 attracts the screw, so the screw will also move upward together with the tightening block 23 and the magnet 24. When the sliding shaft 34 moves towards the electric baking pan, it will drive the sliding table 17, the tightening block 23, and the magnet 24 to move towards the electric baking pan. The screw will also move towards the electric baking pan, moving the screw above the electric baking pan. When the sliding shaft 34 moves downward,It will drive the skateboard 18, the tightening block 23 and the magnet 24 to move downward. The screw will also move downward. The screw will pass through the hole on the heat insulation plate and insert into the screw hole of the electric baking pan. At this time, the screw stops moving downward. The hexagonal sleeve 19 continues to move downward, and the second spring 22 stretches. When the sliding shaft 34 stops moving downward, the hexagonal sleeve 19 also stops moving downward. Then, control the output shaft of the third motor 25 to rotate, driving the hexagonal sleeve 19 on the right side to rotate. The hexagonal sleeve 19 on the right side drives the hexagonal sleeve 19 on the left side to rotate through the sprocket chain. The hexagonal sleeve 19 drives the hexagonal block 20 to rotate. The hexagonal block 20 drives the sliding rod 21 to rotate. The sliding rod 21 drives the tightening block 23 to rotate. The tightening block 23 drives the screw to rotate. The second spring 22 in the stretched state will provide a downward pulling force for the tightening block 23, enabling the tightening block 23 to push the screw downward and screw the screw into the screw hole of the electric baking pan, fixing the heat insulation plate on the electric baking pan, automatically assembling the heat insulation plate and the electric baking pan, being able to tighten multiple screws simultaneously, thus improving the assembly efficiency, and being able to ensure the precise placement of the heat insulation plate, thereby ensuring the assembly accuracy and improving the product quality. After the fixing is completed, the staff sends the screws into the feeding track 26 through the vibrating plate for replenishing the screws. Then, control the output shaft of the second motor 7 to rotate in the reverse direction, driving the lead screw 6 to rotate in the reverse direction through the gearbox 8. The lead screw 6 drives the sliding frame 9 to move upward. The first spring 10 and the second spring 22 return to their original states. The sliding frame 9 drives the straight rack 30 and the electric suction cup 12 to move upward. The straight rack 30 drives the spur gear 29 to rotate in the reverse direction. The spur gear 29 drives the rotating shaft 28 to rotate in the reverse direction. The rotating shaft 28 drives the one-hole plate 31 to rotate in the reverse direction. The one-hole plate 31 drives the sliding shaft 34 to move. The sliding shaft 34 slides along the U-shaped opening 32. The sliding shaft 34 first moves upward, then moves away from the electric baking pan, and finally moves downward. The moving direction of the tightening block 23 is the same as that of the sliding shaft 34. The tightening block 23 will be sleeved on the screw. If the tightening block 23 does not completely correspond to the screw, the tightening block 23 will abut against the upper end of the screw, and the second spring 22 will stretch. It is possible to control the output shaft of the third motor 25 to drive the tightening block 23 to rotate so that the tightening block 23 and the screw completely correspond. The tightening block 23 moves downward under the action of the second spring 22, sleeving the tightening block 23 on the screw to ensure normal assembly next time.

[0039] Refer to Figure 1 、 Figure 11 and Figure 12, further comprising a positioning mechanism, the positioning mechanism includes a guide frame 35, a positioning plate 36, a third spring 37 and a lifting assembly. Guide frames 35 are connected to both the front and rear sides of the top of the frame 1. Positioning plates 36 are slidably connected to the guide frames 35. The left and right parts of the guide frames 35 are sleeved with third springs 37. The two ends of the third spring 37 are respectively connected to the guide frame 35 and the positioning plate 36. The guide frame 35 can support the third spring 37 to prevent the third spring 37 from bending. The lifting assembly is used to lift the positioning plate 36 so that the positioning plate 36 positions the electric baking pan on the placing plate 13.

[0040] Referring to Figure 1 and Figure 12 , the lifting assembly includes a contact shaft 38 and a push plate 39. Contact shafts 38 are rotatably connected to both the left and right sides of the positioning plate 36. Push plates 39 are bolted to both the left and right sides of the bottom of the sliding plate 18. The push plates 39 slidably penetrate through the mounting plate 15. The lower sides of the push plates 39 facing the positioning plate 36 are all inclined surfaces 40. When the push plate 39 pushes the contact shaft 38, the contact shaft 38 will roll on the push plate 39 to avoid friction between the push plate 39 and the contact shaft 38.

[0041] When the sliding table 17 moves towards the electric baking pan, the push plate 39 will also move towards the electric baking pan. The push plate 39 pushes the contact shaft 38 to move upward through the inclined surface 40. The contact shaft 38 drives the positioning plate 36 to move upward, lifting the positioning plate 36, compressing the third spring 37. The positioning plate 36 can position the electric baking pan on the placing plate 13 to ensure that the heat insulation plate can be accurately installed on the electric baking pan, and the positioning plate 36 can limit the electric baking pan to prevent the position of the electric baking pan from shifting.

[0042] Referring to Figure 3 , further comprising guide rods 41. Guide rods 41 are connected to both the front and rear sides inside the sliding frame 91. Two first springs 10 are respectively sleeved on the two guide rods 41. The guide rods 41 can support the first springs 10 to prevent the first springs 10 from bending.
