The device specifically comprises a stacking unit and a conveying unit; the stacking unit is used for placing parts outside the production line, pushing the stacking unit to the appointed position of the conveying unit, and then conveying the parts on the stacking unit to the appointed production station inside the production line through the conveying unit. Parts to be spliced are respectively placed on the stacking units, and then the parts are sequentially conveyed to the designated processing positions by the conveying units according to the set beats, so that accurate transmission of the parts is ensured, and mutual interference is avoided.

Specifically, the stacking unit comprises a transport vehicle 1, and the conveying unit comprises a sliding rail structure 2 and a grabbing structure 3.

The grabbing structure 3 is mounted on the sliding rail structure 2 through a sliding rail and can move back and forth on the sliding rail structure 2 along the length direction of the sliding rail, so that parts are transported from the front end of the sliding rail structure 2 to the rear end of the sliding rail structure 2.

Specifically, as shown in fig. 2, the transport vehicle 1 is 1640mm long; the square transport vehicle 1 with the width of 1600mm, wherein the transport vehicle 1 comprises a vehicle framework 9, and four universal wheels are respectively arranged below the vehicle framework 9, so that the transport vehicle 1 can be moved conveniently. A plurality of stacking frames 6 are fixedly arranged on the vehicle frame 9 side by side through nuts, and the stacking frames 6 comprise a first stacking frame 61 for stacking first parts, a second stacking frame 62 for stacking second parts and a third stacking frame 63 for stacking third parts; the distance between the first stacking frame 61 and the second stacking frame 62 is 385mm; the spacing between the second stack 62 and the third stack 63 is 750mm. Each stacking rack 6 is used for stacking different types of parts, so that the position of each part is accurate when the part is finally transported to the splicing point, and the splicing operation is accurate.

As shown in fig. 3, at least one similar part is stacked on each of the stacking racks 6; in this embodiment, ten parts are stacked on each stacking rack 6. Taking the first stacking frame 61 as an example, as shown in fig. 4, the stacking frame 6 includes supporting frames 7 relatively disposed at two sides of the part, stacking units 64 are respectively disposed on the two supporting frames 7, and in combination with the supporting frames 7 shown in fig. 5, the supporting frames 7 include two upright posts 70 relatively vertically fixed on the frame 9, and in combination with fig. 6, the upright posts 70 are U-shaped square tubes with outward openings, and the lower ends are fixed on the frame 9 through bonding pads.

Based on the difference of the structures of the parts, the fixing requirements for the parts are different, so that a plurality of supporting frames 7 and upright posts 70 for fixing are additionally arranged on two sides of the parts according to the structures of the parts, and the first stacking frame 61 is taken as an example, because the structure of the first part is larger, two supporting frames 7 are additionally arranged on one side of the first part, and two upright posts 70 are additionally arranged on the other side of the first part to serve as reinforcing supports.

Specifically, as shown in fig. 7, the stacking unit 64 includes a plurality of baffle plates 8 disposed between two upright posts 70 at intervals from top to bottom; the upper part and the lower part can be separately fixed through the baffle 8, so that the parts are prevented from being attached together due to the structure, the shape and the like, overlapping grabbing is caused, meanwhile, the parts are also possibly spliced, the structural stability of the parts can be kept through the baffle 8, the extrusion deformation of the parts is avoided, and the subsequent processing is influenced. Wherein, the distance between the upper and lower adjacent baffle plates 8 is 100mm.

The baffle 8 comprises a bearing part 81 and a connecting part 82 which are integrated into an L shape; a rotary ring 10 is integrally welded at the joint of the receiving part 81 and the connecting part 82, and the rotary ring 10 is rotatably sleeved on the positioning pin 85, so that the baffle 8 can rotate clockwise or anticlockwise around the positioning pin 85. With reference to the enlarged partial view shown in fig. 8, a movable rod 83 is welded to the end of the connecting portion 82 away from the rotary ring 10, the movable rod 83 is disposed below the connecting portion 82, and two guide pieces 11 are respectively connected to both ends of the movable rod 83. Wherein, a bar-shaped through hole 101 is arranged at the upper part of the guide plate 11, and a through hole 102 is arranged below the bar-shaped through hole 101. One end of the movable rod 83 is slidably clamped in the strip-shaped through hole 101 of the guide plate 11, and the other end of the movable rod is rotatably connected into the through hole 102 of the other guide plate 11, so that the upper and lower adjacent baffle plates 8 are sequentially connected in series through the guide plates 11.
