Float type butting structure

Abstract

The present invention provides a float type butting structure, and belongs to the field of transportation equipment of production lines or integrated production units. The float type butting structurecomprises a symmetrical flexible butting structure, wherein the flexible butting structure comprises a fixed frame and a floating frame, the fixing frame is fixedly connected with an AGV, the floating frame is arranged on the upper end face of the fixing frame and is arranged relative to the fixing frame in a floating mode, an X-direction spring for limiting the X-axis of the floating frame is arranged between the fixing frame and the floating frame, an Y-direction spring for limiting the Y-axis of the floating frame is arranged, and the upper end of the floating frame is provided with a positioning pin module for positioning goods and a guiding pin module for guiding the goods. According to the float type butting structure, flexible taking and conveying of products can be realized, and meanwhile accurate positioning of the products after the products reach stations can be realized, and automatic butt joint requirements are met.

Description

technical field [0001] The invention belongs to the field of transfer equipment for a production line or an integrated production unit, and relates to applications such as transfer and docking of aerospace large component products, in particular to a floating docking structure. Background technique [0002] In order to realize the automatic docking assembly of large parts, the high-precision positioning of the products after they arrive at the station is very important. Due to the relatively low output of aerospace products, the use of AGV vehicles to realize product transfer can make the logistics system of the production line more flexible and easy to implement The rapid reconstruction of the logistics system with the adjustment of the production line layout, but due to the low positioning accuracy of the AGV vehicle itself (≥5mm) and the high cost of achieving high-precision positioning (using multiple or multiple positioning sensors), it is based on A simple and reliable...

AI Technical Summary

Problems solved by technology

[0003] After patent and literature search, there are two main existing solutions: (1) improve the positioning accuracy of the AGV vehicle by installing multiple or multiple positioning sensors, and then realize the precise positioning of the product after it is in place; (2) the AGV vehicle After the product is transported and placed on the receiving pallet, multiple active drive auxiliary mechanisms (such as pneumatic / electric push rods or clamping mechanisms) are used to perform secondary clamping and positioning to achieve precise positioning. These two methods are costly and The debugging cycle is long and the system reliability is relatively low. In the existing technology, it is difficult for AGV to achieve flexible docking with high-precision positioning devices, which limits the scope of application of AGV
