Description

Technical Field

[0001] The present invention relates to the technical field of material transfer, and particularly to an automated guided vehicle for transporting automotive parts. Background Art

[0002] An automated guided vehicle refers to an unmanned automated vehicle that has automatic guidance devices such as magnetic strips, tracks, or lasers, travels along a pre-planned path, is powered by a battery, and is equipped with safety protection and various auxiliary mechanisms (such as loading and unloading, assembly mechanisms). Automated guided vehicles are widely used in automobile manufacturing plants and are usually used to transport automotive parts, such as transporting materials like engine blocks, car doors, and trunk lids.

[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 automotive parts, and cannot make full use of the vertical space above the vehicle. When manufacturing automotive parts in an automobile manufacturing plant, it is necessary to use transportation guided vehicles to frequently transport a large number of components from the production line to the warehouse. However, traditional guided vehicles are small in size and have a small transportation volume each time, so more vehicles need to work simultaneously or the vehicles need to make frequent round trips, increasing the transportation time and energy consumption.

[0004] Therefore, in view of this, the present invention provides an automated guided vehicle for transporting automotive parts. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an automated guided vehicle for transporting automotive parts to solve the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0007] Automated guided vehicle for transporting automotive parts, including the main body of the guided vehicle, side plates, drive wheels, conveyor belt, and stacking rack.

A clockwork spring is sleeved on the part where the circular sleeve is rotatably connected to the long strip. Three blocking plates are fixedly connected between the two main support plates of the stacking rack. An infrared sensor is provided on the lowermost blocking plate.

[0008] Preferably, four groups of positioning and installation components are provided between the side plates and the stacking rack. The positioning and installation components include sleeves fixedly connected to the stacking rack. A magnetic column is slidably connected inside the sleeve. An auxiliary spring is sleeved on the outer wall of the magnetic column. One end of the auxiliary spring is fixedly connected to the inner wall of the sleeve, and the other end is fixedly connected to the outer wall of the magnetic column. Slots are opened at the positions of the side plates corresponding to the magnetic columns, and electromagnetic blocks with magnetic poles opposite to those of the magnetic columns are provided inside the slots.

[0009] Preferably, a loosening component for loosening the strong ropes and extending them to increase the spacing between materials is provided inside the circular sleeves close to the plurality of second sliding sleeves. The loosening component includes a rectangular groove opened inside the long strip close to the plurality of second sliding sleeves. A tapered column is slidably connected inside the circular sleeve. A top spring is sleeved on the outer wall of the tapered column. One end of the top spring is fixedly connected to the inner wall of the circular sleeve, and the other end is fixedly connected to the tapered column.

[0010] Preferably, a rectangular block is fixedly connected to one end of the conical column close to the rectangular groove. The rectangular block is inserted and adapted to the adjacent rectangular groove. An extrusion plate is fixedly connected to each rectangular frame. Electric telescopic rods II are fixedly connected to the positions of the main support plates of the stacking rack close to the bottom.

[0011] Preferably, support components for supporting the parts stacked on the stacking rack are respectively arranged on the four main support plates of the stacking rack. The support components include movable sleeves evenly and rotatably connected to the four main support plates of the stacking rack. An inclined surface column is slidably connected inside the movable sleeve, and a return spring is sleeved on the outer surface of the inclined surface column.

[0012] Preferably, one end of the return spring is fixedly connected to the inner wall of the movable sleeve, and the other end of the return spring is fixedly connected to the inclined surface column. Electric telescopic rods I are fixedly connected to the four main support plates of the stacking rack.

[0015] Preferably, one end of the clockwork spring is fixedly connected to the circular sleeve, and the other end of the clockwork spring is fixedly connected to the long strip plate.

[0016] The automatic guided vehicle for transporting automobile parts provided by the present invention has the following beneficial effects:

[0017] The long strip plates in the second row and the lifting rods are inserted between the two transmission wheels again, so as to lift the automobile parts newly connected to the guided vehicle body upward. Subsequently, the circular sleeves in the third row will also gradually rise, making the lifting rods in the third row move upward to lift the automobile parts again. At this time, the three rows of lifting rods have all moved upward completely. After that, the conveyor belt on the guided vehicle body will connect another automobile part, and the single transportation volume of the automatic guided vehicle is completed. The parts are stacked upward through the stacking rack, which is equivalent to increasing the multi-layer storage space on the same floor area, allowing more automobile parts to be stored, reducing the number of round trips of the automatic guided vehicle, and saving transportation time and energy consumption.

[0018] When the lifting rods in the second row move upward and drive the circular sleeves in the third row not to fit with the sealing plate, the above steps will be repeated to widen the distance between the lifting rods in the second row and the third row, so as to adapt to the transportation of larger automobile parts.

[0019] The inclined columns on the inner walls of both sides of the stacking rack can provide support for the extrusion plate to prevent the heavy automobile parts from pressing the rectangular frame, long columns and lifting rods downward. The support of the inclined columns and the stacking rack provides additional support for the guide vehicle body to prevent all automobile parts from being placed on the guide vehicle body during transportation, resulting in long-term excessive loads, bending, cracks, etc., and reduce the number of connecting parts on the chassis of the guide vehicle body, such as bolts, welding points, etc., which may also loosen or break due to excessive stress, thereby increasing the service life of the automatic guided vehicle.

[0020] 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.

[0021] 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.

A first sliding sleeve 62 and two second sliding sleeves 63 are sleeved on the outer surfaces of the threaded rod 61 and the long column 69. It should be noted that the inner diameters of the two second sliding sleeves 63 located on the threaded rod 61 are larger than the outer diameter of the threaded rod 61 and will not fit against the outer wall of the threaded rod 61. The first sliding sleeve 62 located on the threaded rod 61 is threadedly connected to the threaded rod 61.

The positions of the guide grooves 68 close to the side plate 2 are provided with inclined grooves inclined towards the side plate 2;

[0034] On the circular sleeves 65 close to multiple second sliding sleeves 63, strong ropes 610 are wound. The strong ropes 610 are made of nylon material, having high strength and wear resistance. One end of each strong rope 610 is fixedly connected to the wound circular sleeve 65, and the other end is fixedly connected to the outer wall of the circular sleeve 65 above it.

Three blocking plates 10 are fixedly connected between the two main support plates of the stacking rack 5. An infrared sensor is arranged on the lowermost blocking plate 10. The three blocking plates 10 are used to block the automotive parts from being conveyed away from the stacking rack 5 by the conveyor belt 4. A plurality of U-shaped grooves are formed on the side plate 2, and the U-shaped grooves are used for the lifting rod 67 to smoothly enter.

[0035] Please refer to Figure 4 and Figure 5 As shown, four groups of positioning and installation components are arranged between the side plate 2 and the stacking rack 5. The positioning and installation components include a sleeve 7 fixedly connected to the stacking rack 5. A magnetic column 71 is slidably connected inside the sleeve 7. An auxiliary spring 72 is sleeved on the outer wall of the magnetic column 71. One end of the auxiliary spring 72 is fixedly connected to the inner wall of the sleeve 7, and the other end of the auxiliary spring 72 is fixedly connected to the outer wall of the magnetic column 71. A slot 73 is formed at the position of the side plate 2 corresponding to the magnetic column 71, and an electromagnetic block with a magnetic pole opposite to that of the magnetic column 71 is arranged in the slot 73.

[0036] Please refer to Figure 2 、 Figure 3 、 Figure 5 and Figures 6 to 8 As shown, a loosening component for loosening and extending the strong ropes 610 to increase the spacing between materials is arranged inside the circular sleeve 65 close to multiple second sliding sleeves 63. The loosening component includes a rectangular groove 8 formed inside the long strip board 66 close to multiple second sliding sleeves 63. A tapered column 81 is slidably connected inside the circular sleeve 65. An ejection spring 82 is sleeved on the outer wall of the tapered column 81. One end of the ejection spring 82 is fixedly connected to the inner wall of the circular sleeve 65, and the other end of the ejection spring 82 is fixedly connected to the tapered column 81. A rectangular block 83 is fixedly connected to one end of the tapered column 81 close to the rectangular groove 8, and the rectangular block 83 is in plug-in fit with the adjacent rectangular groove 8. An extrusion plate 84 is fixedly connected to each rectangular frame 64. The extrusion plate 84 is L-shaped. Electric telescopic rods two 86 are fixedly connected to the positions of the main support plates of the stacking rack 5 close to the bottom. The telescopic ends of the electric telescopic rods two 86 are fixedly connected with a blocking plate 85. The blocking plate 85 is used to fit the guiding groove 68 and apply an extrusion force to the tapered column 81.

[0037] Please refer to Figure 2 、 Figure 3 、 Figure 5 and Figure 9 、Figure 10 As shown in the figure, support components for supporting the parts stacked and supported are respectively arranged on the four main support plates of the stacking rack 5. The support components include movable sleeves 9 evenly and rotatably connected to the four main support plates of the stacking rack 5. A bevel column 91 is slidably connected inside the movable sleeve 9. A return spring 92 is sleeved on the outer surface of the bevel 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 bevel column 91. Electric telescopic rods 94 are fixedly connected to the four main support plates of the stacking rack 5. The telescopic ends of the electric telescopic rods 94 are fixedly connected to long vertical rods 95. A plurality of racks 96 are evenly and fixedly connected to the long vertical rods 95. 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. The rack 96 meshes with the adjacent gear 93. The long vertical rod 95 is slidably connected to the main support plate of the stacking rack 5.

[0038] It should be noted that: A total of three rows of long plates 66 are arranged on both sides of the stacking rack 5, and corresponding circular sleeves 65, rectangular frames 64, and lifting rods 67 are arranged on each long plate 66. The second sliding sleeve 63 is connected to the rectangular frames 64 of the second row and the third row, and the first sliding sleeve 62 is connected to the rectangular frame 64 at the topmost position.

[0039] The following is the entire working process and working principle of the above embodiment:

[0040] Initial state: The conical columns 81 on the circular sleeves 65 in the second row and the third row are in a state of being squeezed by the blocking plates 85. Therefore, the ejecting springs 82 on the conical columns 81 are in a compressed state, and the rectangular blocks 83 at one end of the conical columns 81 are inserted into the rectangular grooves 8 in the long plates 66, making the conical columns 81 and the circular sleeves 65 unable to rotate. Furthermore, the strong ropes 610 are locked outside the circular sleeves 65 and are in a state where they cannot be stretched or loosened. The bevel surface of the bevel column 91 faces downward.

[0041] During operation, first, the guiding vehicle body 1 starts to move. At this time, the electromagnets in the slots 73 are also powered on. The guiding vehicle body 1 automatically moves between the four main support plates of the stacking rack 5. When the guiding vehicle body 1 moves to a position where the slots 73 on its side plate 2 correspond to the magnetic columns 71, the electromagnets in the slots 73 generate magnetic attraction and adsorb to the magnetic columns 71, causing the magnetic columns 71 to slide in the sleeves 7 towards the side plate 2 and compress the auxiliary springs 72, and insert into the corresponding slots 73. At this time, all four magnetic columns 71 on the stacking rack 5 are inserted into the corresponding slots 73, completing the installation and fixation of the stacking rack 5 to the guiding vehicle body 1.

[0042] After that, the guiding vehicle body 1 continues to move forward and drives the stacking rack 5 to move synchronously with the universal wheels at the bottom, so that the side of the guiding vehicle body 1 and the stacking rack 5 away from the baffle 10 approaches the conveyor for transporting automotive parts synchronously. After approaching the conveyor, the guiding vehicle body 1 stops moving. At this time, the conveyor belt 4 on the upper surface of the guiding vehicle body 1 is flush with the conveyor belt on the surface of the conveyor. The automotive parts will then be transferred to the upper surfaces of the conveyor belt 4 and the multiple driving wheels 3 under the action of the conveyor belt of the conveyor. At this time, when the driving motor 6 is turned on, it will drive the driving wheel 3 at the outermost side to rotate, so that the conveyor belt 4 and the driving wheels 3 drive the automotive parts to gradually move in the direction of the baffle 10. When the automotive parts gradually approach the infrared sensor on the baffle 10, the infrared sensor senses and sends a signal to the controller, causing the controller to turn 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 by the strong ropes 610 to the circular sleeves 65 in the second row, the second sliding sleeve 63 and the rectangular frame 64 will also be driven to move upward synchronously through the strong ropes 610. Furthermore, when the rectangular frame 64 on the first sliding sleeve 62 moves upward, it will drive the circular sleeve 65 to slide in the guide groove 68. When the circular sleeve 65 slides to the inclined groove part of the guide groove 68, it will move in the direction of the side plate 2 along the trajectory of the inclined groove, which will drive the long strip 66 to slide in the rectangular frame 64. The long strip 66 will also drive multiple lifting rods 67 to insert from the side plate 2 between the corresponding two driving wheels 3. The multiple lifting rods 67 will gradually fit against the bottom of the automotive parts on the driving wheels 3. As the threaded rod 61 continues to move, it will drive the first sliding sleeve 62 and the lifting rods 67 supporting the automotive parts to move upward synchronously. The multiple lifting rods 67 will pass through between the two driving wheels 3 and move upward to lift the automotive parts. After that, the driving wheels 3 and the conveyor belt 4 will continue to receive automotive parts. At this time, the circular sleeve 65 in the first row will drive the circular sleeve 65 in the second row close to the second sliding sleeve 63 to repeat the above movement through the strong rope 610, so that the long strip 66 and the lifting rods 67 in the second row will be inserted between the two driving wheels 3 again, thereby lifting the automotive parts newly received on the guiding vehicle body 1 upward. Subsequently, the circular sleeve 65 in the third row will also gradually rise, causing the lifting rods 67 in the third row to move upward to lift the automotive parts again. At this time, all three rows of lifting rods 67 have completely moved upward. After that, when the conveyor belt 4 on the guiding vehicle body 1 receives another automotive part, the single transportation volume of the automatic guided vehicle is completed. By stacking the parts upward with the stacking rack 5, it is equivalent to increasing the storage space of multiple layers on the same floor area, being able to store a larger number of automotive parts, reducing the number of trips for the automatic guided vehicle to transport back and forth, and saving transportation time and energy consumption.

[0043] It should be noted that when the circular sleeve 65 on the second sliding sleeve 63 moves upward along the guiding groove 68 and no longer fits with the blocking plate 85, the initially compressed ejecting spring 82 rebounds and drives the conical column 81 and the rectangular block 83 to move synchronously. As a result, the rectangular block 83 no longer engages with the rectangular groove 8 in the long strip plate 66. Consequently, the corresponding circular sleeve 65 is no longer restricted and can rotate. At this time, when the uppermost first sliding sleeve 62 continues to move upward, it will drive the power cord 610 that is no longer restricted to become loose. That is, at this time, the circular sleeve 65 on the second sliding sleeve 63 in the second row will rotate on the long strip plate 66 under the pulling of the power cord 610, and drive the clockwork spring 611 to gradually contract and store energy. That is, when the circular sleeve 65 in the first row moves upward, the circular sleeve 65 in the second row will rotate but not move. During this process, wait for the conveyor belt 4 on the guiding vehicle body 1 to continuously convey parts. The circular sleeve 65, rectangular frame 64, and lifting rod 67 in the second row will be at the position corresponding to the side plate 2. As the power cord 610 on the circular sleeve 65 in the second row is completely loose, the circular sleeve 65 in the first row will pull the circular sleeve 65, second sliding sleeve 63, rectangular frame 64, and lifting rod 67 in the second row upward to lift the automotive part. During this process, the second sliding sleeve 63 will slide on the long strip column 69. During the rotation of the circular sleeve 65 on the second sliding sleeve 63 in the second row, the circular sleeve 65 and lifting rod 67 in the first row gradually move away from the lifting rod 67 in the second row. Thus, the purpose of expanding the distance between the lifting rods 67 in the first row and the second row can be achieved. When the lifting rod 67 in the second row moves upward and drives the circular sleeve 65 in the third row not to fit with the blocking plate 85, the above steps will be repeated to widen the distance between the lifting rods 67 in the second row and the third row, so as to adapt to the transportation of larger automotive parts.

[0044] Further, when the rectangular frames 64 in each row move upward, the pressing plates 84 at their tops also move upward and gradually contact the corresponding inclined surface columns 91, causing the inclined surface columns 91 to be squeezed and move inwardly into the movable sleeve 9, and gradually compressing the return spring 92, so that the rectangular frames 64, the long strip columns 69 and the lifting rods 67 can move upward smoothly. Moreover, each subsequent row of rectangular frames 64 will squeeze the corresponding inclined surface columns 91 to move inwardly. When the three rows of rectangular frames 64, the long strip columns 69 and the lifting rods 67 all move upward to the final position, the pressing plates 84 on the rectangular frames 64 are all in a state of being in contact with the cylindrical surfaces of the inclined surface columns 91. At this time, the pressing plates 84 will rest on the cylindrical surfaces of the inclined surface columns 91. The inclined surface columns 91 on both inner walls of the stacking rack 5 can provide a supporting force for the pressing plates 84, avoiding the situation that the heavy automotive parts press the rectangular frames 64, the long strip columns 69 and the lifting rods 67 to move downward. Moreover, the support of the inclined surface columns 91 and the stacking rack 5 provides an additional supporting force for the AGV body 1, avoiding the situation that all the automotive parts are placed on the AGV body 1 during transportation, resulting in excessive load bearing for a long time, bending, cracking and other conditions, reducing the connection components of the chassis part of the AGV body 1, such as bolts, solder joints, etc., which may also become loose or broken due to excessive stress, and improving the service life of the automated guided vehicle.

[0045] Moreover, after the stacking is completed, the guiding vehicle body 1 moves for transportation, which will drive the stacking rack 5 to move synchronously, and transport the stacked automotive parts to the workbench of the next automotive processing. First, the first electric telescopic rod 94 can be activated to extend, driving the long vertical rod 95 and multiple racks 96 to move horizontally synchronously. The multiple racks 96 will then engage with the corresponding gears 93, and the gears 93 will drive the inclined column 91 and the movable sleeve 9 to rotate 180 degrees, so that the inclined surface of the inclined column 91 faces upward. Then, the driving wheel 3 starts to transfer the bottommost material from the direction away from the baffle 10 to the next automotive part processing table through the conveyor belt 4. At this time, the driving motor 6 rotates in reverse to drive the threaded rod 61 to rotate in 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 in the first row will no longer have a pulling force on the second sliding sleeve 63 and the circular sleeve 65 in the second row through the strong rope 610, and the circular sleeve 65 in the second row will no longer have a pulling force on the circular sleeve 65 in the third row through the strong rope 610. Under the action of gravity, the second sliding sleeve 63 will gradually move downward, driving the corresponding rectangular frame 64, long strip column 69 and lifting rod 67 to move downward. At this time, the pressing plate 84 on the rectangular frame 64 will press the inverted inclined column 91 again, so that the inclined column 91 slides into the movable sleeve 9, which will not affect the downward movement of the rectangular frame 64, long strip plate 66 and lifting rod 67. The order is that the long strip column 69 and the lifting rod 67 in the third row first approach the guiding vehicle body 1, place the material on the conveyor belt 4 on the guiding vehicle body 1 for transmission, and then the automotive parts after the second row and the first row are sequentially unloaded and transported, thus completing the transportation and transfer of the automotive parts.

[0046] It should be noted that when the circular sleeve 65 in the third row and the second sliding sleeve 63 move to the bottommost part of the long strip column 69, the circular sleeve 65 is also at the bottommost part of the guiding groove 68 and will also move downward, driving the conical surface of the conical column 81 to be squeezed by the pressing plate 84. At this time, the threaded rod 61 will drive the first sliding sleeve 62 and the circular sleeve 65 in the first row to move to the uppermost end of the inclined groove position of the guiding groove 68, so that the uppermost lifting rod 67 is in the gap between the driving wheels 3. At this time, the second electric telescopic rod 86 is activated to retract the pressing plate 84, so that the pressing plate 84 no longer presses the corresponding conical column 81. At this time, the conical column 81 rebounds and no longer drives the rectangular block 83 to be inserted into the rectangular groove 8 on the long strip plate 66, so that the circular sleeves 65 in the second row and the third row can rotate. Under the reset and rebound action of the clockwork spring 611, the circular sleeve 65 can rotate to wind up the strong rope 610.
