Description

Technical Field

[0001] This invention belongs to the technical field of transformer processing, specifically a transportation and scheduling device for a transformer production line and its operation method. Background Technology

[0002] In the field of power equipment manufacturing, transformers are the core equipment for power transmission and distribution. From core stacking and winding to transformer body assembly and tank assembly, transformers need to be precisely transferred between multiple workstations on the production line. The different dimensions, weights, and transfer accuracy requirements of different transformer models place stringent demands on the transportation scheduling equipment of the production line.

[0003] Currently, in order to meet the scheduling needs of multiple production line workstations, transformers are mainly transported to different processing workstations by manually operating forklifts and other transportation equipment. This method is inefficient and inconvenient, and there is also a risk of equipment collisions caused by human error, which affects the actual production of transformers. Summary of the Invention

[0004] This invention provides a transportation scheduling device and its operation method for a transformer production line, which can solve the technical problem that it is not convenient to schedule transformers by manually operating transportation equipment in the prior art.

[0005] A transportation and scheduling device for a transformer production line includes an AGV trolley with Mecanum wheels at its bottom. Two fixed components are installed on each side of the AGV trolley, and a connecting plate is snapped into each fixed component. A lifting plate and a hydraulic rod are fixedly installed on the top of the connecting plate. The hydraulic rod is located outside the lifting plate, and the top of the lifting plate and the hydraulic rod are connected to a base plate. An outer plate is fixed to the top edge of the base plate. A flip plate is rotatably connected to the outer plate via a rotating shaft. Several guide rollers are rotatably installed on the base plate. Hydraulic cylinders are fixedly installed on the front, rear, and one side of the outer plate. A push plate is fixedly connected to the drive end of the hydraulic cylinder, and the push plate is located inside the outer plate.

[0006] As a further technical solution of the present invention, the bottom of the flip plate is rotatably connected to the outer plate through a rotating shaft, and a drive motor for driving the flip plate to rotate is fixedly installed on the outside of the outer plate. Several electric rotating rollers are rotatably installed on the inner side of the flip plate. The lifting plate includes two sleeve plates, and a storage groove is opened in the sleeve plate. A sliding plate is sleeved in the storage groove, and the sliding plate is slidably connected to one of the storage grooves.

[0007] As a further technical solution of the present invention, the fixing component includes a fixing plate fixedly installed with the outer plate, and the bottom of the fixing plate is connected to a clamping seat through an electric push rod, and the bottom sides of the clamping seat are provided with slots.

[0008] As a further technical solution of the present invention, the clamping seat is arranged in an inverted U-shape, the connecting plate is arranged in a Z-shape, and both sides of the connecting plate are fixedly installed with card blocks that are compatible with the card slot.

[0009] As a further technical solution of the present invention, two telescopic rods are also connected between the clamping seat and the fixing plate, and the two telescopic rods are located on both sides of the electric push rod.

[0010] As a further technical solution of the present invention, a caster wheel is installed at the bottom of the connecting plate, and the bottom of the caster wheel is flush with the bottom of the Mecanum wheel.

[0011] As a further technical solution of the present invention, the guide roller includes an inner roller body, and a plurality of inserting grooves are equally spaced on the outer wall of the inner roller body. A plurality of balls are rotatably installed in the inserting grooves, and the outer roller body is covered by an outer roller sleeve, with the balls protruding outward from the outer roller sleeve.

[0012] As a further technical solution of the present invention, a slot is provided on one side of the bottom of the receiving base plate, and an installation slot is provided on the top of the AGV trolley directly below the slot. Baffles are fixedly installed on both sides of the installation slot. A lifting bracket is installed inside the installation slot, and a connecting plate is fixedly connected to the top of the lifting bracket. A support plate that matches the slot is fixedly connected to the top of the connecting plate. Several round rollers are rotatably installed on the top surface of the support plate, and a hydraulic rod for driving the connecting plate to rise and fall is fixedly installed at the bottom of the lifting bracket.

[0013] A method for operating a transportation scheduling device for a transformer production line, the method specifically includes the following steps: Step 1: First, the transformer casing is loaded onto the receiving base plate and contacts the guide rollers. The hydraulic cylinder at the rear drives the push plate to block the outside of the transformer casing. After the AGV trolley is driven, it moves through the Mecanum wheels at the bottom and connects with the connecting plate using the fixed components. The clamping seat is engaged with the connecting plate by the downward movement of the electric push rod. The clamping block is inserted into the slot to achieve docking. As the AGV trolley moves, it drives the receiving base plate to move, thus adjusting the transformer casing. Step 2: After the AGV trolley dispatches the transformer to the production line station, the drive motor drives the flip plate to flip up to the horizontal and receive it with the production line's conveyor belt. The hydraulic cylinder on one side drives the push plate to push the transformer shell along the flip plate direction, push the transformer shell onto the flip plate, and finally receive it with the production line's conveyor belt and transport it to the processing station for processing. Step 3: After processing, the transformer shell is returned via the production line's conveyor belt. The height of the receiving base plate is controlled by adjusting the hydraulic rod, and the lifting plate rises and falls accordingly. After the AGV trolley moves horizontally, the electric rollers on the flip plate are used for transmission, so that the production line's conveyor belt can send the processed transformer shell back to the receiving base plate. Step 4: When a defect appears in the processed transformer, the lifting bracket uses the hydraulic rod to drive the connecting plate to move upward, causing the pallet to rise into the slot. At this time, the rear push plate is retracted, and the connected push plate is driven by the front hydraulic cylinder to push the defective transformer shell onto the pallet. Then, the lifting bracket moves downward, causing the transformer shell to move down to the receiving base plate. During the downward movement, a baffle is used for protection to prevent the transformer shell from falling. The electric push rod retracts, causing the locking block to disengage from the slot. The defective transformer shell is then transported to the repair station by the AGV trolley. Afterward, the AGV trolley returns, and the locking block is engaged with the slot by the electric push rod, allowing the scheduling work to resume.

[0014] The beneficial effects of the present invention are as follows: By setting guide rollers on the receiving base plate and cooperating with the guidance of the flip plate, the present invention can easily push the transformer shell to different work positions on different transformer production lines for different processing operations by using a hydraulic cylinder to drive the push plate, thus saving the trouble of manual scheduling. Furthermore, the surface of the outer roller sleeve is provided with protruding balls, which allows the defective transformer housing to smoothly enter the upper part of the pallet when it is pushed onto the pallet by the hydraulic cylinder, thus preventing wear on the guide roller. Even if the guide roller and the round roller are set perpendicularly, it can still ensure that the defective transformer housing can smoothly enter the upper part of the pallet. By setting up a lifting bracket to drive the pallet to move up and down, the pallet can enter the slot to receive the defective transformer shell. With the help of the fixing component, the clamping seat can be separated from the connecting plate by the retraction of the electric push rod. At this time, the slot and the block are separated, and the defective transformer shell can be transported by the AGV trolley alone. This facilitates the rapid transport of the defective transformer shell to the repair station, saves the need to move the entire dispatching equipment, and reduces the wear and tear on the AGV trolley.

[0018] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1-8 As shown, a transportation scheduling device for a transformer production line includes an AGV trolley 1 with Mecanum wheels at the bottom. Two fixing components 2 are installed on each side of the AGV trolley 1, and a connecting plate 3 is snapped into the fixing component 2. A lifting plate 5 and a hydraulic rod 6 are fixedly installed on the top of the connecting plate 3. The hydraulic rod 6 is located outside the lifting plate 5, and the top of the lifting plate 5 and the hydraulic rod 6 are connected to a supporting base plate 7. An outer plate 8 is fixed to the top edge of the supporting base plate 7. A flip plate 11 is rotatably connected to the outer plate 8 through a rotating shaft. Several guide rollers 12 are rotatably installed on the supporting base plate 7. Hydraulic cylinders 9 are fixedly installed on the front, rear and one side of the outer plate 8. A push plate 10 is fixedly connected to the drive end of the hydraulic cylinder 9. The push plate 10 is located inside the outer plate 8.

[0020] The bottom of the flip plate 11 is rotatably connected to the outer plate 8 via a rotating shaft, and a drive motor for driving the flip plate 11 to rotate is fixedly installed on the outside of the outer plate 8. Several electric rollers are rotatably installed on the inner side of the flip plate 11. The lifting plate 5 includes two sleeve plates 501. A storage groove 502 is opened in the sleeve plate 501, and a sliding plate 503 is sleeved in the storage groove 502. The sliding plate 503 is slidably connected to one of the storage grooves 502.

[0021] Specifically, by setting up a flap 11, the flap 11 can be rotated outward to a horizontal state, thereby assisting in transporting the transformer casing to the production line station.

[0022] The fixing component 2 includes a fixing plate 203 fixedly installed with the outer plate 8, and a clamping seat 201 is connected to the bottom of the fixing plate 203 via an electric push rod 204. The clamping seat 201 has slots 202 on both sides of its bottom. The clamping seat 201 is U-shaped. The connecting plate 3 is Z-shaped. The connecting plate 3 has a locking block 14 that matches the slot 202 fixedly installed on both sides. Two telescopic rods are also connected between the clamping seat 201 and the fixing plate 203. The two telescopic rods are located on both sides of the electric push rod 204.

[0023] Specifically, the clamping seat 201 is connected to the connecting plate 3 by driving the electric push rod 204, and the receiving base plate 7 can be integrated with the AGV trolley 1 by engaging the slot 202 with the card block 14. This facilitates the movement of the transformer shell by the AGV trolley 1 along the planned path. After the slot 202 is disengaged from the card block 14, the receiving base plate 7 can be separated from the AGV trolley 1, allowing the AGV trolley 1 to transport defective products independently and reducing the energy consumption of the AGV trolley 1.

[0024] The bottom of the connecting plate 3 is equipped with casters 4, and the bottom of casters 4 is flush with the bottom of the Mecanum wheel.

[0025] Specifically, driven by the Mecanum wheel, the omnidirectional wheel 4 moves synchronously and can rotate to adapt to the travel path of the Mecanum wheel.

[0026] The guide roller 12 includes an inner roller body 121. The outer wall of the inner roller body 121 is provided with a plurality of inserting grooves 123 at equal intervals. A plurality of balls 124 are rotatably installed in the inserting grooves 123. The inner roller body 121 is covered by an outer roller sleeve 122, and the balls 124 protrude outward from the outer roller sleeve 122.

[0027] Specifically, the guide roller 12 can rotate, which facilitates guiding the transformer casing toward the flip plate 11. At the same time, it is equipped with ball bearings 124, which can move the transformer casing toward the pallet 19 when needed, thus avoiding wear on the surface of the guide roller 12.

[0028] A slot 13 is provided on one side of the bottom of the base plate 7. An installation slot 16 is provided on the top of the AGV trolley 1 directly below the slot 13. Baffles 15 are fixedly installed on both sides of the installation slot 16. A lifting bracket 17 is installed inside the installation slot 16.

Several rollers 20 are rotatably installed on the top surface of the support plate 19. A hydraulic rod 21 for driving the connecting plate 18 to rise and fall is fixedly installed at the bottom of the lifting bracket 17.

[0029] Specifically, by raising and lowering the lifting bracket 17, the pallet 19 can be moved upward to support the defective transformer casing, making it easier for it to be removed from the slot 13 and independently scheduled using the AGV trolley 1.

[0030] A method for operating a transportation scheduling device for a transformer production line, the method specifically includes the following steps: Step 1: First, the transformer casing is loaded onto the receiving base plate 7 and contacts the guide roller 12. The hydraulic cylinder 9 at the rear drives the push plate 10 to block the outside of the transformer casing. After the AGV trolley 1 is driven, it moves through the Mecanum wheels at the bottom and connects to the connecting plate 3 using the fixing component 2. The electric push rod 204 moves down and the clamping seat 201 engages with the connecting plate 3. The clamping block 14 engages with the slot 202 to achieve docking. As the AGV trolley 1 moves, it drives the receiving base plate 7 to move, thus adjusting the transformer casing. Step 2: After the AGV trolley 1 dispatches the transformer to the production line station, the drive motor drives the flip plate 11 to flip to the horizontal and receive it with the production line's conveyor belt. The hydraulic cylinder 9 on one side drives the push plate 10 to push the transformer shell along the flip plate 11, push the transformer shell onto the flip plate 11, and finally receive it with the production line's conveyor belt and transport it to the processing station for processing. Step 3: After processing, the transformer shell is returned via the production line's conveyor belt. The height of the receiving base plate 7 is controlled by adjusting the hydraulic rod 6, and the lifting plate 5 is raised and lowered accordingly. After the AGV trolley 1 moves horizontally, the electric roller on the flip plate 11 is used for transmission, so that the production line's conveyor belt can send the processed transformer shell back to the receiving base plate 7. Step 4: When a defect appears in the processed transformer, the lifting bracket 17 uses hydraulic rod 21 to drive the connecting plate 18 to move upward, causing the pallet 19 to rise into the slot 13. At this time, the rear push plate 10 is retracted, and the connected push plate 10 is driven by the front hydraulic cylinder 9 to push the defective transformer shell onto the pallet 19. Then, the lifting bracket 17 is moved downward, causing the transformer shell to move down to the receiving base plate 7. During the downward movement, the baffle 15 is used for protection to prevent the transformer shell from falling. The electric push rod 204 retracts, causing the locking block 14 to disengage from the slot 202. The defective transformer shell is transported to the repair station by the AGV trolley 1. Then, the AGV trolley 1 returns, and the locking block 14 is driven by the electric push rod 204 to engage with the slot 202, so that the scheduling work can be carried out again.

[0031] It should be further noted that patent application CN106744506B discloses an AGV trolley, and the AGV trolley 1 in this application is prior art. Patent application CN108832767B discloses an electric roller, which can be used as the electric roller in this application. Therefore, the movement and path planning of the AGV trolley 1 and the rotation drive of the electric roller will not be described in detail here.
