Description

Technical Field

[0001] The invention relates to the technical field of material transfer, in particular to an automatic guided vehicle for transporting automobile parts. Background Art

[0002] An automated guided vehicle is an unmanned automated vehicle that has automatic guidance equipment such as magnetic strips, tracks or lasers, travels along a planned path, is powered by batteries, and is equipped with safety protection and various auxiliary mechanisms (such as transfer and assembly mechanisms). Automated guided vehicles are widely used in automobile manufacturing plants, usually for transporting automobile parts, such as engine blocks, car doors, trunk lids and other materials.

[0003] In environments such as warehouses or production workshops, space is a very precious resource. Existing automated guided vehicles can only store one layer of materials at a time when transporting auto parts, and cannot fully utilize the vertical space above the vehicle. When producing auto parts in an automobile manufacturing plant, it is necessary to use transport guided vehicles to frequently transport a large number of parts from the production line to the warehouse. Traditional guided vehicles are small in size and have a small transport volume each time, so more vehicles are required to work at the same time or vehicles need to travel back and forth frequently, which increases transportation time and energy consumption.

[0004] In view of this, the present invention provides an automatic guided vehicle for transporting automobile parts. Summary of the invention

[0015] The automatic guided vehicle for transporting automobile parts provided by the present invention has the following beneficial effects: The second row of long strips and lifting rods are inserted between the two transmission wheels again, thereby lifting up the auto parts connected again on the guide vehicle body, and then the circular sleeves in the third row will gradually rise, causing the lifting rods in the third row to move upward and lift up the auto parts again. At this time, all three rows of lifting rods are completely moved up, and then the conveyor belt on the guide vehicle body will connect another auto part to complete the single transportation volume of the automatic guided vehicle. The parts are stacked upward through the stacking rack, which is equivalent to adding multiple layers of storage space on the basis of the same floor space, which can store more auto parts and reduce the number of trips of the automatic guided vehicle back and forth, saving transportation time and energy consumption.

[0018] Under the reset and rebound action of the clockwork spring, the circular sleeve can be rotated to reel in the strong rope, so that the loose components can be reset for the next use. When not in use, the three rows of circular sleeves, long boards, and lifting rods are all located at the bottom of the stacking frame and are in a storage state to avoid taking up space.

[0019] The controller is used to cut off the power to the electromagnetic block in the slot, and the magnetic column is no longer adsorbed. At this time, the auxiliary spring resets and rebounds to drive the magnetic column to disengage from the slot. After that, the guide vehicle body can move out from the inside of the stacking rack. At this point, the stacking rack can be used as a storage rack for stacking automobile parts materials, thereby completing the automatic stacking of the stacking rack. The guide vehicle body can continue to move to the next stacking rack for installation and adaptation. At this point, the automatic stacking of automobile parts can be completed through the cooperation of the guide vehicle body and the stacking rack. There is no need to manually remove the parts from the guide vehicle body for stacking or transfer and storage, which improves the function of the guide vehicle body to transport materials.

The blocking plate 85 is used to fit the guide groove 68 and apply a squeezing force to the tapered column 81 .

[0024] See also Figure 2 , Figure 3 , Figure 5 and Fig. 9 , Fig.10 As shown, the four main support plates of the stacking rack 5 are respectively provided with support components for supporting the stacked parts, and the support components include a movable sleeve 9 which is evenly rotatably connected to the four main support plates of the stacking rack 5, and a sloped column 91 is slidably connected inside the movable sleeve 9, and a return spring 92 is sleeved on the outer surface of the sloped column 91, one end of the return spring 92 is fixedly connected to the inner wall of the movable sleeve 9, and the other end of the return spring 92 is fixedly connected to the sloped column 91, and an electric telescopic rod 94 is fixedly connected to the four main support plates of the stacking rack 5, and the telescopic end of the electric telescopic rod 94 is fixedly connected to a long vertical rod 95, and a plurality of racks 96 are evenly fixedly connected to the long vertical rod 95, and one end of the movable sleeve 9 passing through the main support plate of the stacking rack 5 is fixedly connected to a gear 93, and the rack 96 is meshed with the adjacent gear 93, and the long vertical rod 95 is slidably connected to the main support plate of the stacking rack 5.

[0025] It should be noted that: a total of three rows of long boards 66 are arranged on both sides of the stacking rack 5, and each long board 66 is provided with a corresponding circular sleeve 65, a rectangular frame 64 and a lifting rod 67, the second sliding sleeve 63 is connected to the rectangular frames 64 in the second and third rows, and the first sliding sleeve 62 is connected to the rectangular frame 64 located at the top.

[0026] The following is the entire working process and working principle of the above embodiment: Initial state: the conical column 81 on the circular sleeve 65 in the second and third rows is squeezed by the blocking plate 85, so the ejection spring 82 on the conical column 81 is in a compressed state, and the rectangular block 83 at one end of the conical column 81 is in an inserted state with the rectangular groove 8 in the long plate 66, so that the conical column 81 and the circular sleeve 65 are in a state where they cannot rotate, and then the strong rope 610 is locked outside the circular sleeve 65, in a state where it cannot be stretched or loosened, and the inclined surface of the inclined column 91 faces downward.

[0027] During operation, first the guide vehicle body 1 starts moving, at which time the electromagnetic block in the slot 73 is also energized, and the guide vehicle body 1 automatically moves between the four main support plates of the stacking frame 5. When the guide vehicle body 1 moves to the slot 73 on its side plate 2 corresponding to the magnetic column 71, the electromagnetic block in the slot 73 generates a magnetic attraction force and adsorbs the magnetic column 71, so that the magnetic column 71 slides in the sleeve 7 toward the direction of the side plate 2 to compress the auxiliary spring 72 and insert it into the corresponding slot 73. At this time, the four magnetic columns 71 on the stacking frame 5 are all inserted into the corresponding slots 73, so that the stacking frame 5 is installed and fixed with the guide vehicle body 1.

[0028] After that, the guide vehicle body 1 continues to move and drives the stacking frame 5 to move synchronously with the universal wheel at the bottom, so that the guide vehicle body 1 and the stacking frame 5 away from the blocking plate 10 are synchronously close to the conveyor that is transporting automobile parts. After approaching the conveyor, the guide vehicle body 1 stops moving, and at this time, the conveyor belt 4 on the upper surface of the guide vehicle body 1 is flush with the conveyor belt on the conveyor surface. The automobile parts will be transferred to the upper surface of the conveyor belt 4 and multiple transmission wheels 3 under the action of the conveyor belt. At this time, the drive motor 6 is turned on to drive the transmission wheel 3 located at the outermost side to rotate, so that the conveyor belt 4 and the transmission wheel 3 drive the automobile parts to gradually move toward the direction of the blocking plate 10. When the automobile parts gradually approach the infrared sensor on the blocking plate 10 When the device is turned on, the infrared sensor senses and sends a signal to the controller, so that the controller turns on the driving motor 6. The driving motor 6 rotates to drive the threaded rod 61 to rotate. The threaded rod 61 drives the first sliding sleeve 62, the rectangular frame 64 and the circular sleeve 65 threadedly connected thereto to move upward synchronously. Since the circular sleeves 65 in the first row are connected to the strong ropes 610 on the circular sleeves 65 in the second row, the second sliding sleeve 63 and the rectangular frame 64 are also driven to move upward synchronously through the strong ropes 610. Then, when the rectangular frame 64 on the first sliding sleeve 62 moves upward, it drives the circular sleeve 65 to slide in the guide groove 68. When the circular sleeve 65 slides to the oblique groove portion of the guide groove 68, it will follow the trajectory of the oblique groove in the direction of the side panel 2 As the threaded rod 61 moves, it will drive the long plate 66 to slide in the rectangular frame 64, and the long plate 66 will also drive multiple lifting rods 67 to insert from the side plate 2 between the corresponding two transmission wheels 3. Multiple lifting rods 67 will gradually fit with the bottom of the automobile parts on the transmission wheel 3. As the threaded rod 61 continues to move, the first sliding sleeve 62 and the lifting rods 67 supporting the automobile parts will move upward synchronously. Multiple lifting rods 67 will pass through between the two transmission wheels 3 and move upward to lift the automobile parts upward. After that, the transmission wheel 3 and the conveyor belt 4 will continue to connect the automobile parts. At this time, the circular sleeves 65 in the first row will drive the circular sleeves 65 in the second row close to the second sliding sleeve 63 through the strong rope 610 to repeat the above movement. The second row of long strips 66 and lifting rods 67 are inserted between the two transmission wheels 3 again, thereby lifting up the auto parts connected again on the guide vehicle body 1, and then the circular sleeves 65 in the third row will gradually rise, causing the lifting rods 67 in the third row to move upward and lift up the auto parts again. At this time, the three rows of lifting rods 67 are completely moved up, and then the conveyor belt 4 on the guide vehicle body 1 will connect another auto part to complete the single transportation volume of the automatic guided vehicle. The parts are stacked upward through the stacking rack 5, which is equivalent to adding multiple layers of storage space on the basis of the same floor space, which can store more auto parts, reduce the number of trips of the automatic guided vehicle back and forth, and save transportation time and energy consumption.

[0029] It should be noted that when the circular sleeve 65 on the second sliding sleeve 63 moves upward along the guide groove 68 until it is no longer in contact with the blocking plate 85, the ejection spring 82 that was initially compressed resets and rebounds to drive the conical column 81 and the rectangular block 83 to move synchronously, so that the rectangular block 83 is no longer plugged into the rectangular groove 8 in the long plate 66, and then the corresponding circular sleeve 65 will no longer be restricted and can rotate. At this time, when the top first sliding sleeve 62 continues to move upward, it will drive the strong rope 610 that is no longer restricted to loosen, that is, at this time, the circular sleeve 65 on the second sliding sleeve 63 in the second row will rotate on the long plate 66 as the strong rope 610 pulls, and drive the clockwork spring 611 to gradually contract and accumulate force, that is, at this time, when the circular sleeve 65 in the first row moves upward, the circular sleeve 65 in the second row will rotate and will not move, waiting for the conveyor belt 4 on the guide vehicle body 1 to continue to convey parts, and the second The circular sleeves 65, rectangular frames 64 and lifting rods 67 of the first row will be at a position corresponding to the height of the side panel 2. As the strong ropes 610 on the second row of circular sleeves 65 are completely loosened, the circular sleeves 65 of the first row will pull the circular sleeves 65, second sliding sleeves 63, rectangular frames 64 and lifting rods 67 of the second row to move upward and hold up the automobile parts. During the process, the second sliding sleeves 63 will slide on the long column 69. During the rotation of the circular sleeves 65 on the second sliding sleeves 63 of the second row, the circular sleeves 65 and lifting rods 67 of the first row gradually move away from the lifting rods 67 of the second row, thereby achieving the purpose of expanding the distance between the lifting rods 67 of the first row and the second row. When the lifting rods 67 of the second row move upward and drive the circular sleeves 65 of the third row to not fit with the blocking plate 85, the above steps will be repeated to open the distance between the lifting rods 67 of the second row and the third row, so as to accommodate larger automobile parts for transportation.

[0030] Furthermore, when each row of rectangular frames 64 moves upward, the extrusion plate 84 at the top thereof will also move upward and gradually contact the corresponding inclined plane column 91, so that the inclined plane column 91 is squeezed and moves toward the inside of the movable sleeve 9, and gradually compresses the return spring 92, so that the rectangular frame 64, the long column 69 and the lifting rod 67 can move upward smoothly, and each subsequent row of rectangular frames 64 will squeeze the corresponding inclined plane column 91 to move inward. When the three rows of rectangular frames 64, the long column 69 and the lifting rod 67 all move upward to the final position, the extrusion plates 84 on the rectangular frames 64 are in a state of fitting with the cylindrical surface of the inclined plane column 91, and at this time, the extrusion plates 84 will be in contact with the cylindrical surface of the inclined plane column 91. On the cylindrical surface of the inclined column 91, the inclined column 91 on the inner wall of both sides of the stacking frame 5 can provide support force for the extrusion plate 84, so as to prevent the heavy automobile parts from pressing the rectangular frame 64, the long column 69 and the lifting rod 67 downward. In addition, the support of the inclined column 91 and the stacking frame 5 provides additional support force for the guide vehicle body 1, so as to prevent all automobile parts from being placed on the guide vehicle body 1 during transportation, resulting in long-term excessive load, bending, cracks, etc., and reduce the connection parts of the chassis part of the guide vehicle body 1, such as bolts, welding points, etc., which may also loosen or break due to excessive force, thereby improving the service life of the automatic guided vehicle.

[0031] And, after the stacking is completed, the guide vehicle body 1 will move for transfer, which will drive the stacking frame 5 to move synchronously, and transport the stacked automobile parts to the next automobile processing workbench. The electric telescopic rod 94 can be started to extend, driving the long vertical rod 95 and multiple racks 96 to move horizontally synchronously, and the multiple racks 96 will mesh with the corresponding gears 93. The gear 93 will drive the inclined column 91 and the movable sleeve 9 to rotate 180 degrees synchronously, so that the inclined surface of the inclined column 91 faces upward, and then the transmission wheel 3 is turned on to transfer the bottom material from the direction away from the blocking plate 10 to the next automobile part processing table through the conveyor belt 4. At this time, the driving motor 6 reverses to drive the threaded rod 61 to reverse, and the threaded rod 61 will drive the first sliding sleeve 62 to gradually move downward. At this time, the first sliding sleeve 62 and the circular sleeve 65 of the first row will no longer be connected by the strong rope 6 10 has a pulling force on the second sliding sleeve 63 and the circular sleeve 65 of the second row, and the circular sleeve 65 of the second row no longer has a pulling force on the circular sleeve 65 of the third row through the strong rope 610. Under the action of gravity, the second sliding sleeve 63 will gradually move downward, and drive the corresponding rectangular frame 64, the long column 69 and the lifting rod 67 to move downward. At this time, the extrusion plate 84 on the rectangular frame 64 will press the flipped inclined column 91 again, so that the inclined column 91 slides toward the movable sleeve 9, which will not affect the downward movement of the rectangular frame 64, the long plate 66 and the lifting rod 67. The order is that the long column 69 and the lifting rod 67 of the third row first approach the guide vehicle body 1, and place the material on the conveyor belt 4 on the guide vehicle body 1 for transmission, followed by the second row and the first row of automobile parts after unloading and transportation in sequence, thereby completing the transportation and transportation of automobile parts.

[0032] It should be noted that when the circular sleeve 65 of the third row and the second sliding sleeve 63 move to the bottom of the long column 69, the circular sleeve 65 is also located at the bottom of the guide groove 68, and will also move downward, driving the conical surface of the conical column 81 to be squeezed by the squeezing plate 84. At this time, the threaded rod 61 will drive the first sliding sleeve 62 and the circular sleeve 65 of the first row to move to the uppermost end of the inclined groove position of the guide groove 68, so that the uppermost row of lifting rods 67 is in the gap between the transmission wheels 3. At this time, the electric telescopic rod 2 86 starts to retract the squeezing plate 84, so that the squeezing plate 84 no longer squeezes the corresponding conical column 81. At this time, the restoration and rebound of the conical column 81 no longer drives the rectangular block 83 to plug into the rectangular groove 8 on the long plate 66, so that the circular sleeves 65 in the second and third rows can rotate. Under the restoration and rebound action of the clockwork spring 611, the circular sleeves 65 can rotate to reel in the strong rope 610. At this point, the loose components can be restored for the next use. When not in use, the three rows of circular sleeves 65, the long plate 66, and the lifting rod 67 are all located at the bottom of the stacking frame 5 and are in a storage state to avoid taking up space.

[0033] The guide vehicle body 1 is then moved to the next stacking rack 5, and the guide vehicle body 1 is ...
