Description

Technical Field

[0001] This utility model relates to a picking and delivery frame used on a gearbox assembly line, specifically a single picking and delivery frame for a gearbox shaft system sub-assembly assembly line. Background Technology

[0002] With increasingly fierce competition in the automotive market and diversified consumer demands, transmission manufacturers need to offer more customized products and services to meet the individual needs of different customers. This trend has driven the development of multi-variety, small-batch production methods, which in turn places higher demands on the efficiency, flexibility, and assembly precision of production lines. Companies must achieve efficient material management and assembly processes within limited production space to cope with rapidly changing market demands.

[0003] Chinese patent application CN214268370U discloses a positioning tray for automated production of bevel gears, including a trolley and a tray stacked on the trolley. The tray has several through holes and several positioning holes arranged around the through holes. Positioning elements are arranged in the positioning holes or through holes. The number of positioning elements arranged around the through holes is at least three. This solution solves the problem that gears or parts are easily misplaced on the tray in the prior art. However, for gearbox shaft sub-assemblies, there are still problems of low delivery efficiency and high error rate.

[0004] Chinese patent application publication number CN208963581U discloses a turnover box for shaft parts, including a main frame and several auxiliary frames stacked on top of the main frame. Limiting stops are provided between the main frame and the auxiliary frames and between adjacent auxiliary frames to limit the position of adjacent parts. The box also includes a positioning frame located in the main frame and having several positioning holes for shaft parts to pass through, a limiting baffle that is engaged with the bottom of the positioning frame and abuts against the shaft parts passing through the positioning holes, and several sets of adjusting and locking components respectively located between the main frame and the limiting baffles to adjust and fix the limiting baffles. Adjusting the position of the limiting baffle relative to the main frame by adjusting the locking components allows for adjustment of the insertion depth of shaft parts that abut against the limiting baffle. With the help of auxiliary frames, it is suitable for holding shaft parts of different specifications. The layered auxiliary frames are conducive to stacking multiple layers of shaft parts, thus improving its versatility and reducing the floor space. However, for the gearbox shaft sub-assembly line, due to the large variety of parts in the line-side storage area and the complexity of management, there are still problems such as low part delivery efficiency, high error rate, and difficulty in achieving accurate delivery and efficient assembly, which affects the production efficiency and quality of the production line.
