Description

Technical Field

[0001] The invention relates to the technical field of parts transportation, and in particular to an adjusting device for an AGV trolley. Background Art

[0002] In the traditional automobile processing production line, the engine assembly line adopts a motorized roller type. The pallet is placed on the motorized roller, and the engine is placed on the pallet. During the automatic assembly process, the upper side plane of the pallet needs to be kept horizontal, so that the engine on the pallet can be directly installed on the installation position on the vehicle without adjustment after being separated from the pallet. In the process of adjusting the level of the pallet, the pallet can be kept horizontal through the adjustment nut on the motorized roller, but the overall volume of the motorized roller is large. AGV carts are often used to transport auto parts nowadays, but due to the particularity of the engine and the uneven ground of the factory area, the pallet on the AGV cart cannot remain horizontal. At the same time, there will be errors in the position where the AGV cart stays during transportation, which may deviate from the set position by about 5mm. Ultimately, the engine on the AGV trolley pallet cannot be accurately docked with the installation position on the vehicle, reducing the assembly efficiency of the car. Under the existing technology, such as patent CN202323022529.7, the invention is a hook-pull type AGV trolley pallet transfer machine. When the pallet on the AGV trolley is docked, the unlocking cylinder, the unlocking bumper, the positioning block, the cable stop hook and the slider cooperate to make the cable stop hook release the positioning block, and then the positioning is completed by the cooperation between the rotating drive cylinder, the rotating hook and the positioning block, and the pallet on the AGV trolley is sent to the next positioning point by the carrying roller to realize the transfer of the engine on the pallet. The invention uses a transplanting mechanism to separate the pallet from the AGV trolley and allow the pallet to run onto the roller, and subsequent pallets perform related operations on the roller. The system requires the pallet to be separated from the AGV before the relevant operations can be carried out. Moreover, the patent does not completely break away from the use of motorized rollers, which still occupies space within the factory. At the same time, the pallet is transferred from the AGV to the motorized roller and then from the motorized roller to the vehicle. The engine has to go through multiple handling workpieces for transportation, which is time-consuming and has low efficiency. Summary of the invention

[0003] The purpose of the present invention is to provide an adjustment device for an AGV trolley to solve the problem that when an engine on a pallet is transported by an AGV trolley in the prior art, the pallet on the upper side of the AGV trolley cannot remain level with the ground, resulting in position deviation of the engine itself during the automatic installation of the engine.

DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0024] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0026] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0027] Under the existing technology, engine parts on pallets are generally transported by motorized roller conveyors, but motorized roller conveyors take up more space in the factory. If the production line is improved, the motorized roller conveyors need to be repaved. If AGV carts are used for transportation, the uneven factory floor and the inertial parking position of the AGV cart will have an error of less than 5mm, which will cause the pallet to be unable to be in a horizontal state and the placement of the engine will also be tilted. During the automatic assembly process, the engine will deviate from the expected position and require secondary adjustment to connect to the vehicle body, reducing production efficiency.

[0028] In order to solve the above problems, Figures 1 to 7 As shown, the present invention provides an adjustment device for an AGV trolley, which includes a tray assembly and an adjustment assembly 3. The tray assembly is installed on the AGV trolley 4. A gap is formed between the adjustment assemblies 3. The AGV trolley 4 is parked in the gap. The tray assembly includes an upper tray 1 and a lower tray 2. The lower tray 2 is fixed on the AGV trolley 4. The upper tray 1 is connected to the lower tray 2 through a spring member 5. A first limiting column 11 is installed on the upper side of the upper tray 1. The adjustment assembly 3 includes a first cylinder 31. The first cylinder 31 pushes a first push block 33 to move. The first push block 33 abuts against the first limiting column 11. A plug-in groove is formed on the lower side of the upper tray 1. A second cylinder 32 is installed on the adjustment assembly 3. The second cylinder 32 pushes a lifting block 35 in a lifting mechanism 34 to move perpendicular to a horizontal plane. The lifting block 35 is plugged into the plug-in groove.

[0029] By flexibly connecting the upper tray 1 and the lower tray 2 using the spring member 5, after the AGV trolley 4 enters the gap between the adjusting devices, the first limit column 11 is pushed by the first cylinder 31 to move the upper tray 1 relative to the lower tray 2, so that the upper tray 1 can coincide with the set position in the horizontal direction, and then the lifting block 35 is adjusted by the second cylinder 32 so that the lifting block 35 can adjust the height of the upper tray 1 in the vertical direction so that the upper tray 1 can be parallel to the horizontal plane, and finally the engine on the upper tray 1 can be directly aligned with the installation part on the vehicle body, thereby realizing automated installation and improving production efficiency.

[0030] The present invention has adjustment components 3 installed on both sides, which include four groups of first cylinders 31. The first cylinders 31 are symmetrically installed on both sides of the moving direction of the AGV trolley 4, with two groups of first cylinders 31 installed on each side. The first cylinders 31 correspond to the first push blocks 33 one by one.

[0031] The direction in which the AGV trolley 4 enters the adjustment component 3 is set as the X-axis, the direction perpendicular to the plane of the lower tray 2 is set as the Z-axis, and the Y-axis is perpendicular to the X-axis and the Z-axis respectively.

[0032] Two groups of first cylinders 31 are installed on both sides of the upper tray 1 symmetrically. If the symmetry axis of the upper tray 1 in the length direction of the X-axis forms an angle with the X-axis, the first push blocks 33 are pushed synchronously by the two groups of first cylinders 31 on each side, so that the first push blocks 33 can hook and correct the upper tray 1 so that the symmetry axis of the upper tray 1 in the X-axis direction can coincide with the X-axis. The angle of the upper tray 1 is adjusted so that the upper tray 1 can coincide with the set position, so that the engine and the vehicle body can be automatically aligned during the subsequent automatic installation of the engine, thereby improving the installation efficiency.

[0033] The first push block 33 on one side of the AGV trolley 4 is rectangular, and a V-shaped notch 331 is formed on the first push block 33 on the other side of the AGV trolley 4 . The V-shaped notch 331 abuts against the first limiting column 11 .

[0034] When the first support block with the V-shaped notch 331 abuts against the first limiting column 11, the V-shaped notch 331 can accumulate and correct the position of the upper tray 1 in the X-axis direction, so that the upper tray 1 can move to the set position along the X-axis direction, and the first push blocks 33 on both sides can adjust the upper tray 1 to move to the set position along the Y-axis direction.

[0035] Four groups of plug-in slots are formed on the lower side of the upper tray 1, and four groups of second cylinders 32 are installed in the adjustment component 3. The second cylinders 32, the lifting mechanisms 34 and the plug-in slots correspond one to one. Two groups of second cylinders 32 are installed on both sides of the AGV trolley 4.

[0036] Through the four groups of second cylinders 32, the upper tray 1 can be stably pushed up and adjusted to be parallel to the horizontal plane so that the upper tray 1 can coincide with the set height. At the same time, through the adjustment of the second cylinders 32 on all sides, the upper tray 1 can also be kept horizontal without tilting.

[0037] The spring component 5 includes an upper connecting block 51, a lower connecting block 52 and a tension spring 53. Both ends of the tension spring 53 are hung on a spring seat 54. A hook 55 is installed on the spring seat 54. The ear at the end of the tension spring 53 is hung on the hook 55. A first screw hole is formed on the spring seat 54. The upper connecting block 51 and the lower connecting block 52 are respectively provided with a second screw hole. The stud 56 is inserted into the first screw hole and the second screw hole. The upper connecting block 51 is installed on the upper tray 1, and the lower connecting block 52 is installed on the lower tray 2.

[0038] When the upper tray 1 is pushed and moved by the first pushing block 33 and the lifting block 35, the tension spring 53 between the upper connecting block 51 and the lower connecting block 52 changes the relative position between the upper tray 1 and the lower tray 2 by expansion and contraction. At the same time, when the engine detaches from the upper tray 1 and the first pushing block 33 and the lifting block 35 are separated from the upper tray 1, the tension spring 53 is deformed again to enable the upper tray 1 to return to its original position, so that the upper tray 1 can be stably installed on the lower tray 2 and there will be no shaking problem during the transportation of the AGV trolley 4.

[0039] Four sets of spring members 5 are respectively arranged on both sides of the lower tray 2 along the X-axis direction, and two sets of spring members 5 are respectively arranged on both sides of the lower tray 2 along the Y-axis direction. By arranging the spring members 5, when the upper tray 1 moves relative to the lower tray 2, the pulling force can be shared, thereby extending the service life of the tension spring 53.

[0040] An adjustment member 6 is installed between the upper tray 1 and the lower tray 2. The adjustment member 6 includes a transition plate 61 and a base 62. The base 62 is installed on the lower tray 2, and the transition plate 61 is installed on the lower side of the upper tray 1. A universal ball 63 is formed on the base 62, and an arc groove is formed on the lower side of the transition plate 61. The universal ball 63 is embedded in the arc groove.

[0041] The upper tray 1 will rotate slightly relative to the lower tray 2, so by providing a universal ball 63 on the base 62, the arc groove of the transition plate 61 can rotate on the universal ball 63 to avoid interference. When the lifting block 35 adjusts the height of the upper tray 1, the arc groove will rotate around the universal ball 63, so that the adjustable position of the upper tray 1 becomes larger, and when the AGV car 4 is parked on an undulating road surface, the upper tray 1 can remain level.

[0042] A floating assembly 7 is also installed between the upper tray 1 and the lower tray 2. The floating assembly 7 includes a floating lower seat 72 and a floating upper seat 71. The floating lower seat 72 is fixed on the lower tray 2. A floating bolt 74 is screwed on the floating lower seat 72. A top cover 73 is passed through the floating bolt 74. The top cover 73 abuts against the upper tray 1. A floating hole is opened on the upper tray 1. The floating upper seat 71 is passed through the floating hole. The floating lower seat 72 is passed through the floating upper seat 71. The outer diameter of the floating lower seat 72 is smaller than the inner diameter of the floating upper seat 71.

[0043] By setting the top cover 73, the maximum height of the floating upper seat 71 in the upper tray 1 can be limited. At the same time, the floating component 7 is set on the axis of the X-axis. The upper tray 1 together with the floating upper seat 71 is moved and adjusted on the outside of the floating lower seat 72. The mutual friction between the floating upper seat 71 and the floating lower seat 72 can prevent the upper tray 1 from direct wear.

[0044] A hook 8 is installed on the first limit column 11, which is convenient for the automatic hook 8 device in the factory to lift the pallet assembly. It is also convenient to place the pallet assembly on the AGV cart 4. A weight-reducing hole 9 is opened on the upper pallet 1 to reduce the maximum weight of the upper pallet 1, and then the working status of the spring part 5, the floating assembly 7 and the adjustment component 6 can be observed through the weight-reducing hole 9.

[0045] The adjusting assembly 3 is installed on the lower side of the engine installation area, and the installation position is adjusted so that the upper tray 1 can be moved to the installation position when the first push block 33 is extended and the lifting block is lifted. Then the AGV trolley drives in and stops. Then the first cylinders 31 on both sides push the first push block 33 to abut against the first limit column 11, and the second cylinder 32 pushes the lifting block 35 in the lifting mechanism 34 to rise and abut against the lower side of the upper tray 1. Finally, the upper tray 1 corrects its own position, so that the engine can be automatically installed to the target position under the adjustment of the upper tray 1, thereby shortening the installation time and improving the processing efficiency.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
