Description

Technical Field

[0001] This invention relates to the field of electric baking pan assembly technology, and in particular to an automated electric baking pan assembly device and method. Background Technology

[0002] During the assembly of an electric baking pan, a heat insulation plate is usually installed at the bottom of the pan. The heat insulation plate reduces heat loss and ensures a more uniform temperature on the surface of the pan, thereby improving the cooking effect. At the same time, the heat insulation plate can also prevent people from accidentally coming into contact with high-temperature areas during use, thus improving safety.

[0003] During the assembly of an electric baking pan, the installation of the heat insulation plate is usually done manually. First, the heat insulation plate is placed at the bottom of the baking pan, then one hand is used to press down on the heat insulation plate, while the other hand uses an electric screwdriver to tighten the screws to fix the heat insulation plate to the baking pan. Installing the heat insulation plate requires multiple screws, but manual operation can only install one screw at a time, which makes the entire assembly process time-consuming and inefficient. Moreover, manual operation is prone to errors, which may result in the heat insulation plate not being installed securely or being misaligned, affecting product quality. Summary of the Invention

[0004] To overcome the drawbacks of manual assembly, which can only assemble one screw at a time, resulting in a long assembly time, low assembly efficiency, and the potential for errors that may lead to insecure installation or misalignment of the heat insulation board, thus affecting product quality, this invention provides an automated assembly device and method for electric baking pans.

[0005] The technical solution is as follows: An automated assembly equipment for electric baking pans includes a frame, a connecting frame, a storage box, a rotating frame, a first motor, a lead screw, a second motor, a gearbox, a sliding frame, a first spring, a mounting frame, an electric suction cup, a feeding mechanism, and an installation mechanism. The connecting frame is connected to the top of the frame, and a storage box for storing heat insulation boards is connected to the top of the connecting frame. The rotating frame is rotatably connected to the top of the connecting frame. The first motor is mounted on the top of the connecting frame, and its output shaft is connected to the rotating frame via gear transmission. A lead screw is rotatably connected to the rotating frame, and a gearbox is mounted on the top of the rotating frame. The gearbox has an output shaft and an input shaft. The output shaft of the gearbox is connected to the upper end of the lead screw. A second motor is installed on the top of the gearbox. The output shaft of the second motor is connected to the input shaft of the gearbox. A sliding frame is slidably connected to the rotating frame. The lead screw and the sliding frame are connected by threads. A sliding frame is slidably connected to the sliding frame. A first spring is connected between the sliding frame and the sliding frame. A mounting frame is connected to the sliding frame. An electric suction cup for picking up the heat insulation plate is installed at the bottom of the mounting frame. A feeding mechanism is used to transport the electric baking tray to directly below the electric suction cup. The electric suction cup installs the heat insulation plate onto the electric baking tray. The mounting mechanism is used to install screws onto the heat insulation plate and the electric baking tray, fixing the heat insulation plate onto the electric baking tray.

[0006] Preferably, the feeding mechanism includes a placement plate and a conveyor. The top of the frame is connected to the placement plate for placing the electric baking pan, and the top of the placement plate is equipped with a conveyor for conveying the electric baking pan directly below the electric suction cup.

[0007] Preferably, the installation mechanism includes a mounting plate, guide rails, a slide table, a sliding plate, a hexagonal sleeve, a hexagonal block, a slide rod, a second spring, a tightening block, a magnet, a third motor, a feeding track, and a rotating assembly.

A slide table is slidably connected to both sides of the two guide rails, and a sliding plate is slidably connected inside each slide table. Hexagonal sleeves are rotatably connected to both sides of the bottom of each sliding plate. The two hexagonal sleeves are driven by a sprocket and chain, and a hexagonal block is slidably connected inside each hexagonal sleeve. Each diamond-shaped block has a sliding rod connected to its bottom. The sliding rod slides through the bottom of the hexagonal sleeve. A second spring connects the hexagonal sleeve and the hexagonal block. Each sliding rod has a tightening block connected to its lower end. Each tightening block contains a magnet. Each slide plate has a third motor installed on its top. The output shaft of the third motor is connected to the upper end of the hexagonal sleeve on the right side. Feeding rails are connected to both the front and rear sides of the connecting frame. The screw slides along the feeding rails to the bottom of the slide plate. The tightening block is fitted onto the screw, and the magnet holds the screw in place. The rotating component controls the slide plate to rotate, installing the screw onto the heat insulation plate and the electric baking pan.

[0008] Preferably, the rotating assembly includes a vertical plate, a rotating shaft, a spur gear, a spur rack, a slotted plate, a mounting block, and a sliding shaft.

A U-shaped opening is opened on each vertical plate. A mounting block is connected to the top of each sliding plate, and a sliding shaft is rotatably connected to each mounting block. The sliding shaft is located inside the slotted plate and the U-shaped opening. As the spur rack moves downward, it meshes with the spur gear and drives the spur gear to rotate. The spur gear drives the rotating shaft to rotate, and the rotating shaft drives the sliding plate to rotate, allowing the screws to be installed onto the heat insulation plate and the electric baking pan.

[0009] Preferably, the device also includes a positioning mechanism, which includes a guide frame, a positioning plate, a third spring, and a lifting assembly. The guide frame is connected to both the front and rear sides of the top of the frame, and the positioning plate is slidably connected to each guide frame. The third spring is connected between the guide frame and the positioning plate. The lifting assembly is used to lift the positioning plate so that the positioning plate positions the electric baking tray on the placement plate.

[0010] Preferably, the lifting assembly includes a contact shaft and a push plate. The contact shaft is rotatably connected to the positioning plate, and the push plate is connected to the bottom of the slide plate. The push plate slides through the mounting plate, and the side of the lower part of the push plate facing the positioning plate is inclined. The push plate pushes the contact shaft upward through the inclined surface to lift the positioning plate and position the electric baking tray on the placement plate.

[0011] Preferably, the slide frame also includes a guide rod, with the guide rod connected inside the slide frame and the first spring sleeved on the guide rod.

[0014] S2: Control the output shaft of the first motor to rotate, and rotate the electric suction cup to the top of the storage box. Control the output shaft of the second motor to rotate, and move the electric suction cup into the storage box. The electric suction cup will hold the heat insulation plate in the storage box. Control the output shaft of the second motor to rotate in the opposite direction, and remove the heat insulation plate from the storage box. Control the output shaft of the first motor to rotate, and rotate the electric suction cup to the top of the electric baking pan.

[0015] S3: Control the output shaft of the second motor to rotate, which drives the electric suction cup to move downward. The electric suction cup drives the heat insulation plate to move downward, and the heat insulation plate is installed on the electric baking tray for assembly.

[0016] S4: The rack drives the spur gear to rotate, the spur gear drives the shaft to rotate, and the shaft drives the slide plate to rotate, so that the screws can be installed on the heat insulation plate and the electric baking pan;

[0017] S5: Controls the output shaft of the third motor to rotate, which drives the tightening block to rotate. The tightening block drives the screw to rotate, screwing the screw into the screw hole of the electric baking pan, thus fixing the heat insulation plate on the electric baking pan.

[0018] The beneficial effects of this invention are as follows: 1. This invention can drive the heat insulation plate downward by the output shaft of the second motor to install the heat insulation plate onto the electric baking pan for assembly. The output shaft of the third motor can drive the screw to rotate, screwing the screw into the screw hole of the electric baking pan to fix the heat insulation plate onto the electric baking pan. The invention automatically assembles the heat insulation plate and the electric baking pan, and can tighten multiple screws at the same time, thereby improving assembly efficiency and ensuring the accurate placement of the heat insulation plate, thus ensuring assembly accuracy and improving product quality.

[0019] 2. The positioning plate can be used to position the electric baking pan on the placement plate, ensuring that the heat insulation plate can be accurately installed on the electric baking pan. The positioning plate can also limit the position of the electric baking pan to prevent it from shifting. Attached Figure Description

[0037] Reference 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 slotted plate 31, a mounting block 33, and a sliding shaft 34. The top of the left guide rail 16 is bolted to the vertical plate 27 on both the front and rear sides. The upper middle of the vertical plate 27 is rotatably connected to the rotating shaft 28. The left end of the rotating shaft 28 is keyed to the spur gear 29. The front and rear sides of the sliding frame 9 are bolted to the rack 30. The rack 30 will mesh with the spur gear 29 during downward movement. The right end of the rotating shaft 28 is connected to the slotted plate 31. The upper part of the vertical plate 27 has a U-shaped opening 32. The top left side of the slide plate 18 is bolted to the mounting block 33. The upper part of the mounting block 33 is rotatably connected to the sliding shaft 34. The sliding shaft 34 is located in the slotted plate 31 and the U-shaped opening 32.

[0038] Initially, screws are installed in the feeding track 26, and tightening blocks 23 are fitted onto the screws. Magnets 24 hold the screws in place. The operator places the electric baking tray on the placement plate 13, and the conveyor 14 transports the electric baking tray directly below the electric suction cup 12. Then, multiple heat insulation boards are stacked in the storage frame 3. The output shaft of the first motor 5 is then controlled to rotate, which drives the rotating frame 4 to rotate via gears. The rotating frame 4 drives the sliding frame 9 to rotate, which in turn drives the electric suction cup 12 to rotate, moving it directly above the storage frame 3. Then, the output shaft of the second motor 7 is controlled to rotate, which drives the lead screw 6 to rotate via gearbox 8. The lead screw 6 moves the sliding frame 9 downward, which in turn moves the electric suction cup 12 downward, moving it to the storage frame 3. Inside, the electric suction cup 12 contacts and holds the heat insulation plate at the top of the storage box 3. The first spring 10 is compressed, providing a downward thrust to the electric suction cup 12, ensuring a tight contact between the electric suction cup 12 and the heat insulation plate. This ensures the electric suction cup 12 firmly holds the heat insulation plate. Then, the output shaft of the second motor 7 is controlled to rotate in the reverse direction, which in turn drives the lead screw 6 to rotate in the reverse direction via the gearbox 8. The lead screw 6 drives the sliding frame 9 to move upward, which in turn drives the electric suction cup 12 to move upward. The electric suction cup 12 then drives the heat insulation plate upward, removing it from the storage box 3. Finally, the output shaft of the first motor 5 is controlled to rotate, which in turn drives the rotating frame 4 to rotate via the gearbox. The rotating frame 4 then drives the sliding frame 9 to rotate, which in turn drives the sliding frame 9 to rotate. The electric suction cup 12 rotates, positioning itself directly above the electric baking pan. Then, the output shaft of the second motor 7 rotates, driving the lead screw 6 via the gearbox 8. The lead screw 6 moves the sliding frame 9 and sliding bracket 91 downwards. The sliding bracket 91 moves the electric suction cup 12 downwards, and the electric suction cup 12 moves the heat insulation plate downwards, mounting it onto the electric baking pan. At this point, the bottom of the sliding frame 91 contacts the top of the connecting frame 2, stopping the downward movement of the sliding frame 91 and the electric suction cup 12. The sliding frame 9 continues to move downwards, compressing the first spring 10. The sliding frame 9 then moves the rack 30 downwards. During this downward movement, the rack 30 meshes with the spur gear 29, causing the spur gear 29 to rotate. Wheel 29 drives shaft 28 to rotate, shaft 28 drives slotted plate 31 to rotate, slotted plate 31 drives sliding shaft 34 to move. Sliding shaft 34 slides along U-shaped opening 32. Sliding shaft 34 first moves upward, then moves closer to the electric grill pan, and finally moves downward. When sliding shaft 34 moves upward, it drives slide plate 18, tightening block 23, and magnet 24 to move upward. Magnet 24 attracts the screw, so the screw also moves upward with tightening block 23 and magnet 24. When sliding shaft 34 moves closer to the electric grill pan, it drives slide table 17, tightening block 23, and magnet 24 to move closer to the electric grill pan, and the screw also moves closer to the electric grill pan, moving the screw above the electric grill pan. When sliding shaft 34 moves downward...This causes the slide plate 18, tightening block 23, and magnet 24 to move downwards, and the screw also moves downwards. The screw passes through the hole in the heat insulation plate and inserts into the screw hole of the electric baking pan. At this point, the screw stops moving downwards, and the hexagonal sleeve 19 continues to move downwards. The second spring 22 stretches, and when the sliding shaft 34 stops moving downwards, the hexagonal sleeve 19 also stops moving downwards. Then, the output shaft of the third motor 25 is controlled to rotate, driving the right hexagonal sleeve 19 to rotate. The right hexagonal sleeve 19 drives the left hexagonal sleeve 19 to rotate through the sprocket and chain. The hexagonal sleeve 19 drives the hexagonal block 20 to rotate. The rhombus-shaped block 20 drives the slide bar 21 to rotate, which in turn drives the tightening block 23 to rotate. The tightening block 23 then drives the screw to rotate. The second spring 22, under tension, provides a downward pull to the tightening block 23, allowing it to push the screw downwards and screw it into the screw hole of the electric baking pan. This fixes the heat insulation plate onto the electric baking pan, automatically assembling it. Multiple screws can be tightened simultaneously, improving assembly efficiency and ensuring precise placement of the heat insulation plate, thus guaranteeing assembly accuracy and improving product quality. After fixing, the operator... The screws are fed into the feeding track 26 via a vibratory feeder to replenish the screws. Then, the output shaft of the second motor 7 is controlled to rotate in the reverse direction, which drives 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 first spring 10 and the second spring 22 return to their original positions. The sliding frame 9 drives the rack 30 and the electric suction cup 12 to move upward. The rack 30 drives the spur gear 29 to rotate in the reverse direction, which drives the rotating shaft 28 to rotate in the reverse direction. The rotating shaft 28 drives the slotted plate 31 to rotate in the reverse direction, and the slotted plate 31 drives the sliding shaft 34 to move. The sliding shaft 34 enters along the U-shaped opening 32. The sliding shaft 34 first moves upward, then away from the electric baking pan, and finally downward. The tightening block 23 moves in the same direction as the sliding shaft 34, and will fit onto the screw. If the tightening block 23 is not perfectly aligned with the screw, it will press against the top of the screw, and the second spring 22 will stretch. This will control the output shaft of the third motor 25 to rotate the tightening block 23, ensuring that it is perfectly aligned with the screw. Under the action of the second spring 22, the tightening block 23 moves downward, fitting onto the screw to ensure proper assembly next time.

[0039] Reference Figure 1 , Figure 11 and Figure 12It also includes a positioning mechanism, which includes a guide frame 35, a positioning plate 36, a third spring 37, and a lifting assembly. The top front and rear sides of the frame 1 are connected to the guide frame 35, and the positioning plate 36 is slidably connected to the guide frame 35. The left and right sides of the guide frame 35 are fitted with the third spring 37. The two ends of the third spring 37 are connected to the guide frame 35 and the positioning plate 36 respectively. 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 tray on the placement plate 13.

[0040] Reference Figure 1 and Figure 12 The lifting assembly includes a contact shaft 38 and a push plate 39. The left and right sides of the positioning plate 36 are rotatably connected to the contact shaft 38. The left and right sides of the bottom of the slide plate 18 are connected to the push plate 39 by bolts. The push plate 39 slides through the mounting plate 15. The lower part of the push plate 39 facing the positioning plate 36 is a slope 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 slide 17 moves toward the electric baking pan, the push plate 39 also moves toward the electric baking pan. The push plate 39 pushes the contact shaft 38 upward through the inclined surface 40. The contact shaft 38 drives the positioning plate 36 upward, lifting the positioning plate 36. The third spring 37 is compressed. The positioning plate 36 can position the electric baking pan on the placement plate 13 to ensure that the heat insulation plate can be accurately installed on the electric baking pan. The positioning plate 36 can also limit the electric baking pan to prevent the position of the electric baking pan from shifting.

[0042] Reference Figure 3 It also includes guide rods 41. Guide rods 41 are connected to both the front and rear sides of 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 and prevent the first springs 10 from bending.
