Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile manufacturing, specifically to a flexible APC aerial transport vehicle. Background Technology
[0002] With the overall improvement in quality levels in the automotive industry, automation is becoming increasingly sophisticated, and high-cycle production lines are now commonplace in China. Existing welding plants typically boast automation rates exceeding 80%, with cycle times of 102 seconds and vehicle model changeover frequencies of 10 units per changeover. Grinding time is evenly distributed within the cycle time, and vehicle model changeover time must be included within a single cycle. Equipment availability exceeds 94% (equipment utilization rate calculation formula: equipment utilization rate = MTBF / (MTBF+MTTR)). In such high-cycle production lines, due to limited floor space, overhead conveyors are often used to increase buffering and reduce the impact of malfunctions on production. To effectively improve production efficiency, the project team will utilize APC (Automatic Carrier Processing) conveyors in the design to increase buffering. This involves integrating multiple carts into the APC conveyor system for inter-station transfer. However, ensuring the compatibility of these carts with multiple vehicle models is a challenge. Typical overhead APC conveyors can only handle a single vehicle model and suffer from poor stability, leading to line grabbing failures. Utility Model Content
[0003] To address the aforementioned problems, this invention proposes a flexible APC (Automatic Packet Control) aerial transport trolley. This trolley uses limiting blocks to restrict the assembly's X / Z directions, enabling the robot to stably pick up and assemble various vehicle assemblies from the APC trolley. This increases aerial buffering, reduces the impact of malfunctions on production, and improves production efficiency. The specific technical solution is as follows:
[0004] A flexible APC aerial transport trolley has a trolley mounting plate as its main body. A left boom and a right boom are fixedly mounted on both sides of the trolley mounting plate, respectively. The left boom and the right boom are configured in an arc shape. One side of the left boom and the right boom is fixed to the trolley mounting plate, and the other side is equipped with a Z-direction limiting block. The left boom and the right boom are fixed to the rear side by a transverse connecting plate. An L-shaped connecting frame is set on the transverse connecting plate, and an X / Y direction limiting block is fixed to the front end of the L-shaped connecting frame.
[0005] Furthermore, two Z-direction limiting blocks are respectively installed on the left and right booms, and the two Z-direction limiting blocks are fixedly installed on the left and right booms through transition parts.
[0006] Furthermore, a shim is installed between the Z-direction limiting block and the transition piece. The height of the Z-direction limiting block is adjusted by adjusting the thickness of the shim to match different body-in-whites.
[0007] Furthermore, the left and right booms are fixed to the trolley mounting plate by equilateral angle steel and bolts.
[0008] Furthermore, the X / Y direction limiting blocks are made of nylon material, and their shape matches and engages with the shape of the B-pillar of the white body.
[0009] Furthermore, the Z-direction limiting block is made of nylon, and its shape matches and engages with the shape of the upper beam of the white body.
[0010] This utility model relates to a flexible APC (Automatic Packaging Assembly) conveyor trolley. The trolley uses limiting blocks to restrict the assembly in the X / Z directions, enabling an automated production line robot to stably pick up and assemble assemblies of various car models from the APC trolley. This increases overhead buffering, reduces the impact of malfunctions on production, and improves efficiency. It effectively solves the compatibility and stability problems of overhead conveying APCs for various car models, increases overhead buffering to reduce the impact of malfunctions on production, and improves efficiency. The design is novel, ingenious, and practical. Attached Figure Description

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] like Figure 1-4 As shown, a flexible APC aerial transport trolley has a trolley mounting plate 15 as its main body. A left boom 6 and a right boom 7 are fixedly installed on both sides of the trolley mounting plate 15, respectively. The left boom and the right boom are configured in an arc shape. One side of the left boom and the right boom is fixed to the trolley mounting plate, and the other side is equipped with Z-direction limiting blocks 11 / 12 / 13 / 14. The left boom 6 and the right boom 7 are fixed to the rear side by a transverse connecting plate 1. An L-shaped connecting frame 10 is set on the transverse connecting plate 1, and an X / Y direction limiting block 2 is fixed to the front end of the L-shaped connecting frame 10.
[0020] Two Z-direction limiting blocks are respectively installed on the left boom 6 and the right boom 7. The left side is block 11 / 12 and the right side is block 13 / 14. The two Z-direction limiting blocks are fixedly installed on the left boom and the right boom through transition parts. The left side is transition part 8 and the right side is transition part 9.
[0021] A shim is installed between the Z-direction limiting block and the transition piece. The height of the Z-direction limiting block is adjusted by adjusting the thickness of the shim to match different body-in-whites. The shim is 4 on the left and 5 on the right. The left boom 6 and the right boom 7 are fixed to the trolley mounting plate by equal-sided angle steel 3 and bolts.
[0022] The X / Y direction limiting block 2 is made of nylon and its shape matches and engages with the shape of the B-pillar of the white body. The Z direction limiting support block is made of nylon and its shape matches and engages with the shape of the upper beam of the white body.
[0023] When using this car, if Figure 5 As shown, the upper beam of the white car body is suspended on the Z-direction limiting block of the trolley boom. The nylon elastic material used in the block effectively protects the car body. The X / Y direction limiting block 2 engages with the B-pillar of the white car body, so that the white car body is firmly fixed on the trolley. Then, the robot moves the white car body.
[0024] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
