[0043] See also Figures 1-12 As shown, an embodiment structure of the present invention is provided.

[0044] This embodiment provides an AGV for dual-vehicle splicing vehicle assembly, including a first AGV 11, a second AGV 12, a mobile support tooling 13, and a fixed support tooling 14;

[0045] A first connecting mechanism is provided at one end of the first AGV11, and a second connecting mechanism is provided at one end of the second AGV12. The first AGV11 is hingedly connected to the second connecting mechanism of the second AGV12 through the first connecting mechanism; the fixed support tooling 14 is installed on the upper end surface of the first AGV11, and the mobile support tooling 13 is installed on the upper end surface of the second AGV12 and can move along the length direction of the second AGV12. The fixed support tooling 14 and the mobile support tooling 13 are used in combination.

[0046] The present application provides an AGV for assembling a double-car splicing vehicle. The AGV structure includes a first AGV 11 and a second AGV 12. The two AGVs are connected. One end of the first AGV 11 is provided with a first connecting mechanism, and one end of the second AGV 12 is provided with a second connecting mechanism. The first AGV 11 is hingedly connected to the second connecting mechanism of the second AGV 12 through the first connecting mechanism. The two AGVs can rotate slightly around the hinge using this structure, thereby solving the problem of part of the driving wheels being suspended in the air and the vehicle slipping when the vehicle is traveling on an uneven road surface. In addition, the fixed support tooling is installed on the upper end face of the first AGV 11, and the mobile support tooling that can move along the length direction of the second AGV 12 is installed on the upper end face of the second AGV 12. The fixed support tooling and the mobile support tooling are used in conjunction with each other to support assembly components.

[0047] In a preferred embodiment, the mobile support tooling includes a first support tooling and a moving mechanism, and the first support tooling is moved by the moving mechanism; the first support tooling includes a first mounting frame 101 installed on the upper end face of the second AGV12, and a first support unit with the same structure is installed on each of the four corners of the first mounting frame 101, and the four first support unit structures are symmetrically arranged on the left and right.

[0048] Any first support unit includes a first longitudinal frame 103 installed on a first mounting frame 101, a first planar support block 109 is installed at the upper end of the first longitudinal frame 103, a first fixed block 104 is installed at both ends of the inner side of the first longitudinal frame 103, each of the first fixed blocks 104 is hingedly connected to a first hinge block 105, and the two first hinge blocks 105 are fixedly connected to an inclined support block 107 whose lower end face is horizontal and whose upper end face is an inclined surface with a higher outer side and a lower inner side. This structure enables the inclined support block 107 to be flipped.

[0049] The first support fixture has two usage states: 1. When using the inclined support block 107, the lower end of the inclined support block is pressed against the first planar support block 109, and the upper end of the inclined support block is used to support the assembly component; 2. When using the first planar support block 109, the inclined support block 107 is flipped inwardly to the inside of the first longitudinal frame 103, thereby fully exposing the first planar support block 109 and using the first planar support block to support the assembly component. This structure allows the selection of the most suitable usage state according to the specific shape of the component.

[0050] The present application provides a mobile supporting tooling, which can support assembly components when in use. The assembly components are placed above the four first supporting units, which solves the problem of the assembly components being placed directly on the AGV body and causing damage to the AGV body. In addition, targeted settings are made for the assembly components, and the four first supporting units are used in combination to effectively support the assembly components. Moreover, the first supporting tooling has two working states, the first being to use the inclined support block for support, and the second being to use the first plane support block for support. The structural design of the two states can expand the scope of application of the first supporting tooling, so that a suitable structure can be selected according to the appearance of the assembly components.

[0051] In a preferred embodiment, the upper end surfaces of the first planar support block 109 and the inclined support block 107 are respectively provided with a first polyurethane plate 106 and a second polyurethane plate 108. The above structure can protect the components and the support blocks.

[0052] In a preferred embodiment, a pair of first mounting holes 130 are provided at each end of the first mounting frame 101 along its length, spaced apart from each other. The left and right first support units, correspondingly mounted at each end of the first mounting frame 101, are secured by bolts passing through the first mounting holes 130. By installing the first support units at different locations, the distance between the two first support units used together at the same end can be adjusted, thereby adapting to different components.

[0053] In a preferred embodiment, the first supporting tooling moves along the length direction of the second AGV through a moving mechanism, and a second mounting frame 117 is installed on the upper end surface of the second AGV along the length direction of the second AGV. The first mounting frame 101 is slidably connected to the second mounting frame 117 and can move along the second mounting frame 117. Two limiting wheels 102 for limiting the left and right positions of the first supporting tooling when moving are respectively installed on the left and right sides of the first mounting frame 101. The limiting wheels 102 are used in conjunction with the second mounting frame 117 and can rotate on the second mounting frame 117.

[0054] In a preferred embodiment, the second mounting frame 117 is two I-beams spaced apart and arranged in parallel, and the groove on the limiting wheel 102 is stuck on the upper side of the I-beam and rotates along the upper side of the I-beam.

A fixing plate is provided above the first mounting frame 101, and the fixing plate is provided with a first elongated hole 112 arranged in the same direction as the second elongated hole 114. The fixing plate is connected to the first mounting frame 101 via a mounting bolt 113 passing through the first elongated hole 112. The first mounting shaft 111 of the limiting wheel 102 passes through the second elongated hole 114 and the through hole of the fixing plate from bottom to top, and the upper end is threadedly connected to the fixing nut 110, thereby securing the first mounting shaft. Utilizing this structure, the position of the limiting wheel can be adjusted by moving the first mounting shaft within the first elongated hole, facilitating adjustment and installation.

[0056] This embodiment provides a specific structure of a mobile mechanism, which includes a drive motor 115, a transmission rod 116, a driving wheel 120, a driven wheel 119, and a synchronous belt 118. The drive motor 115 is mounted on the upper end surface of the second AGV. The transmission rod 116 passes horizontally through one end of the second mounting frame 117 and is rotatably connected. A driving wheel 120 is mounted on each end of the transmission rod 116, and a driven wheel 119 is mounted on each side of the other end of the second mounting frame 117. The driving wheels 120 and driven wheels 119 on the corresponding sides are connected by a synchronous belt 118. The drive motor 115 is in transmission connection with the transmission rod 116, thereby driving the driving wheel, driven wheel, and synchronous belt to rotate. The two sides of the first mounting frame 101 are fixedly connected to the synchronous belt on the corresponding side. The movement of the synchronous belt 118 drives the movement of the first mounting frame 101. This adjusts the position of the first supporting tooling on the second AGV.

[0057] Preferably, the driven wheel 119 is mounted on a third mounting bracket 121. The third mounting bracket 121 is provided with four third elongated holes along the length of the second AGV. Bolts pass through the third elongated holes to secure the third mounting bracket 121 to the second mounting bracket 117. A second fixing block 122 is mounted on one side of the third mounting bracket 121. A threaded push rod 123 passes through the second fixing block 122 and is threadedly connected to the second fixing block 122. One end of the threaded push rod 123 presses against the third mounting bracket 121. This structure allows the position of the third mounting bracket 121 to be adjusted, thereby adjusting the tension of the timing belt 118.

[0058] Preferably, the fixed support tooling 14 includes two second support units with symmetrical left and right structures, the second support unit includes a second planar support block 124, a second longitudinal frame 125, a grooved support block 126, a first mounting plate 127, a Z-shaped hinge 128, and a third fixed block 129.

Each of the third fixed blocks 129 is hingedly connected to one side of the grooved support block 126 through a Z-shaped hinge block, and the upper end of the grooved support block 126 is provided with a groove.

[0059] It should be noted that the fixed support fixture is used in conjunction with the first support fixture to jointly support the assembly component. The fixed support fixture also has two usage states. The first is when the grooved support block 126 is used to support the assembly component, with the lower end surface of the grooved support block 126 pressing against the second planar support block 124. The second is when the second planar support block 124 is used to support the assembly component, the grooved support block 126 is flipped to the side of the second planar support block 124, and the second planar support block is used for support.

[0060] Preferably, the first connecting mechanism is a groove structure and the second connecting mechanism is an insert block structure, and the groove structure and the insert block structure are used in conjunction with each other. When connected, the insert block structure is inserted into the groove structure, and the two are hingedly connected.

[0062] The plug-in block structure includes an insert-in block located at one end of the second AGV 12 body. A connecting shaft 1202 is passed through the insert-in block in a transverse direction. The connecting shaft 1202 is rotatably connected to the insert-in block. Both ends of the connecting shaft 1202 are provided with longitudinal notches 1201.

[0063] The ends of the connecting shaft 1202 pass through the U-shaped slots on the corresponding U-shaped slot plate 1106 and are then inserted into the mounting slot. The pressure block 1108 of the corresponding pressure piece is inserted into the longitudinal notch 1201 to retain the connecting shaft. Furthermore, the connecting shaft is connected to the second AGV body via a flexible sleeve with a rubber sleeve, which passes through the center hole of the rubber sleeve.

[0064] The structure provided in this embodiment allows the two vehicles to rotate slightly around the hinge, thereby solving the problem of partially hanging driving wheels and causing the vehicles to slip when traveling on uneven roads. In addition, this structure is easy to install.

[0065] In a preferred embodiment, a limiting guide structure is provided on each of the first AGV11 bodies on both sides of the outer end of the groove. The limiting guide structure includes a moving seat 1103, two transverse long holes 1104 are provided on the moving seat 1103, and bolts pass through the transverse long holes 1104 to connect the moving seat 1103 to the first AGV11 body.
