Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of part transportation, and in particular to an adjusting device for an AGV trolley. BACKGROUND

[0002] On a traditional automobile processing production line, an engine assembly line adopts a motorized roller type, a tray is placed on the motorized roller, an engine is placed on the tray, and in the automatic assembly process, the upper side plane of the tray needs to be kept in a horizontal state, so that the engine on the tray can be directly installed on the installation position of the vehicle without adjustment after being separated from the tray. In the process of adjusting the level of the tray, the adjusting nut on the motorized roller can keep the tray horizontal. However, the overall volume of the motorized roller is large, and AGV trolleys are often used to transport automobile parts today. However, due to the particularity of the engine and the unevenness of the factory floor, the tray on the AGV trolley cannot be kept in a horizontal state, and the position where the AGV trolley stops during transportation may also have an error, which may deviate from the set position by about 5mm, ultimately making the engine on the AGV trolley tray unable to accurately dock with the installation position on the vehicle, reducing the assembly efficiency of the automobile. Under the prior art, such as patent CN202323022529.7, the invention is a hook-pulling type AGV trolley tray transfer machine. When the tray on the AGV trolley cart is docked, the cooperation between the unlocking cylinder, the unlocking block, the positioning block, the hook and the sliding block makes the hook loosen the positioning block, and then the cooperation between the rotating drive cylinder, the rotating hook and the positioning block completes the positioning, and the tray on the AGV trolley cart is sent into the lower positioning point by the carrying roller, realizing the transfer of the engine on the tray. The invention transfers the tray from the AGV trolley through the transfer mechanism, so that the tray runs to the roller, and the subsequent tray performs related operations on the roller. The system needs to separate the tray from the AGV trolley to realize the related operation content, and the patent still uses the motorized roller and occupies space in the factory area. At the same time, the tray is transferred from the AGV trolley to the motorized roller and then transferred from the motorized roller to the vehicle, and the engine is transferred through multiple workpieces, which takes a long time and has a low efficiency.

In addition, it should be noted that, for the convenience of description, only the parts related to the present application are shown in the drawings, but not all the structures.

[0024] In the description of the present application, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0025] In the present application, unless otherwise explicitly specified and limited, the first feature "on" or "under" the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them.

[0027] Under current technology, engine parts on pallets are generally transported by motorized roller conveyors. However, motorized roller conveyors take up a lot of space in the factory area. If the production line is improved, the motorized roller conveyor needs to be re-laid. If AGVs are used for transportation, the uneven factory ground and the inertial positioning of the AGVs can cause the pallets to be unable to be level. As a result, the engine will be tilted. During the automatic assembly process, the engine will deviate from the expected position and require secondary adjustment to connect with the vehicle body, reducing production efficiency.

[0028] To solve the above problems, such as Figures 1 to 7 As shown, the present invention provides an adjustment device for an AGV trolley, including a tray assembly and an adjustment assembly 3. The tray assembly is installed on the AGV trolley 4, and a gap is formed between the adjustment assemblies 3. The AGV trolley 4 stops 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 by a spring member 5. A first limiting post 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 post 11. An insertion 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 the horizontal plane. The lifting block 35 is inserted into the insertion groove.

[0029] By flexibly connecting the upper pallet 1 and the lower pallet 2 using spring 5, after the AGV trolley 4 enters the gap between the adjustment devices, the first cylinder 31 pushes the first limit post 11, causing the upper pallet 1 to move relative to the lower pallet 2, so that the upper pallet 1 can coincide with the set position in the horizontal direction. Then, the second cylinder 32 adjusts the lifting block 35, so that the lifting block 35 can adjust the height of the upper pallet 1 in the vertical direction, so that the upper pallet 1 can be parallel to the horizontal plane. Finally, the engine on the upper pallet 1 can be directly aligned with the mounting part on the vehicle body, realizing automated installation and improving production efficiency.

[0030] The present invention has an adjustment assembly 3 installed on both sides, which includes four sets of first cylinders 31. The first cylinders 31 are symmetrically installed on both sides of the AGV trolley 4 in the direction of movement. Two sets of first cylinders 31 are installed on each side. The first cylinders 31 correspond one-to-one with the first push block 33.

[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 Z-axis respectively.

[0032] Two sets of first cylinders 31 are installed on each of the two symmetrical sides of the upper tray 1. If the axis of symmetry of the upper tray 1 in the X-axis direction is at an angle to the X-axis, the two sets of first cylinders 31 on each side will simultaneously push the first push block 33 so that the first push block 33 can hook and correct the upper tray 1, so that the axis of symmetry of the upper tray 1 in the X-axis direction can coincide with the X-axis. Adjust the angle of the upper tray 1 so that the upper tray 1 can coincide with the set position, which is convenient for the engine to be automatically aligned with the vehicle body during the subsequent automatic engine installation, thus improving the installation efficiency.

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

[0034] When the first support block with the V-shaped notch 331 comes into contact with the first limiting post 11, the position of the upper tray 1 in the X-axis direction can be corrected through the V-shaped notch 331, so that the upper tray 1 can move to the set position along the X-axis direction, while 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 sets of insertion slots are formed on the lower side of the upper tray 1. Four sets of second cylinders 32 are installed in the adjustment component 3. The second cylinders 32, the lifting mechanism 34 and the insertion slots correspond one-to-one. Two sets of second cylinders 32 are installed on each side of the AGV trolley 4.

[0036] The upper tray 1 can be stably lifted by four sets of second cylinders 32, and the upper tray 1 can be adjusted to be parallel to the horizontal plane so that the upper tray 1 can coincide with the set height. At the same time, the upper tray 1 can also be kept horizontal and will not tilt by adjusting the second cylinders 32 around the perimeter.

[0037] The spring component 5 includes an upper connecting block 51, a lower connecting block 52, and a tension spring 53. The two ends of the tension spring 53 are hooked onto the spring seat 54. A hook 55 is installed on the spring seat 54. The ear at the end of the tension spring 53 is hooked onto 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 second screw holes. A stud 56 passes through 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 moved by the first push block 33 and the lifting block 35, the tensile 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 stretching and contracting, and when the engine is separated from the upper tray 1 and the first push block 33 and the lifting block 35 are separated from the upper tray 1, the upper tray 1 can return to the initial position by the deformation of the tensile spring 53 again, so that the upper tray 1 can be stably installed on the lower tray 2 and will not shake during the transportation of the AGV 4.

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

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

[0041] The upper tray 1 will rotate relative to the lower tray 2 by a small amplitude, so the universal ball 63 is arranged on the base 62, the arc-shaped groove of the transition plate 61 can rotate on the universal ball 63 to avoid interference, and when the lifting block 35 adjusts the height of the upper tray 1, the arc-shaped groove rotates around the universal ball 63, so that the adjustable position of the upper tray 1 becomes larger, and when the AGV 4 stops on the undulating road surface, the upper tray 1 can be kept horizontal.

[0042] A floating assembly 7 is further arranged 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 arranged in the floating bolt 74, the top cover 73 abuts against the upper tray 1, a floating hole is arranged on the upper tray 1, the floating upper seat 71 is arranged in the floating hole, the floating lower seat 72 is arranged in the floating upper seat 71, and the outer diameter of the floating lower seat 72 is smaller than the inner diameter of the floating upper seat 71.

[0043] By arranging the top cover 73, the maximum height of the movement of the floating upper seat 71 in the upper tray 1 can be limited, and the floating assembly 7 is arranged on the axis of the X-axis, the upper tray 1 moves together with the floating upper seat 71 outside the floating lower seat 72, and the floating upper seat 71 and the floating lower seat 72 rub against each other to avoid direct wear of the upper tray 1.

[0044] The first limiting column 11 is provided with a lifting hook 8, so that the tray assembly can be lifted by an automatic lifting hook 8 device in the factory area, and the tray assembly can be placed on the AGV trolley 4.

[0045] The adjusting assembly 3 is installed on the lower side of the engine mounting area, and the mounting position is adjusted, so that the upper tray 1 can be moved to the mounting position when the first push block 33 is extended and the jacking block is lifted. Then the AGV trolley drives in and stops, then the first cylinder 31 on both sides pushes the first push block 33 to abut against the first limiting column 11, the second cylinder 32 pushes the lifting block 35 in the jacking mechanism 34 to rise and abut against the lower side of the upper tray 1, finally the upper tray 1 corrects its position, so that the engine can be automatically mounted to the target position under the adjustment of the upper tray 1, the mounting time is shortened, and the machining efficiency is improved.
