Description

Technical Field

[0001] The utility model relates to gearbox production, in particular to a distribution tray for a gearbox rear cover subassembly station. Background Art

[0002] The transmission rear cover assembly station requires a large number of different parts for each unit, including output flanges, bearings, bearing seats, various gears, gear pressure plates, spindles, forks, cylinders, washers, synchronizers, shaft covers, dust covers, etc. The parts are of many types and quantities. If each part is delivered separately, that is, the storage method mostly uses line-side flow racks, and sets line-side inventory water levels, when it is below the water level, the information system will call for material delivery. Not only will the number of deliveries be too many, but the excessive number of parts will also be a great test for the attention and physical strength of the assembly technicians. According to the lean production concept, automobile factories mostly use a parts delivery method of single-quantity set feeding, that is, a complete set of lean logistics distribution systems (SPS), and design single-unit picking pallets for the corresponding workstations for this logistics model.

[0003] Chinese patent CN219687862U discloses a vertical clamping limit tray for rod-shaped workpieces, including a receiving pit and a limit pit. The pits serve as the vertical limit pits for the rod-shaped workpieces, which facilitate the inspection or assembly of the rod-shaped workpieces and eliminate the need for external jigs and tooling. Chinese patent CN215205912U discloses a recyclable limit tray, including a tray body and a plurality of support blocks arranged at the bottom of the tray body. The upper surface of the tray body is provided with a plurality of straight-line limit blocks, and adjacent straight-line limit blocks form a limit area. The limit area is used to limit the placement of the goods to prevent them from colliding during transportation. Similar limit structures are disclosed in the above two patents, but their structures are complex and are not suitable for limiting a large number of parts. They are mainly used to limit and fix workpieces and cannot be used in distribution systems. Therefore, in view of the situation where a large number of different parts are required for a single unit of a subpackaging station, a distribution tray with a simple structure and strong applicability is urgently needed.
