Flexible docking and rapid positioning system

Abstract

The invention provides a flexible docking and rapid positioning system, and belongs to the field of transport equipment of production lines or integrated production units. The flexible docking and rapid positioning system comprises a positioning frame system and an automatic guided vehicle (AGV); the AGV is provided with a flexible docking system; a cargo is transferred to the positioning frame system from the AGV under bearing of flexible docking structures; the positioning frame system includes positioning frames; the upper end of each positioning frame is provided with a positioning pin module and a guide pin module, wherein the positioning pin module is used for performing positioning on the cargo, and the guide pin module is used for guiding the cargo; the flexible docking system includes the flexible docking structures which are symmetric; each flexible docking structure includes a fixed frame and a floating frame; an X direction spring for limiting the X axis of the floating frame and Y direction springs for limiting the Y axis of the floating frame are arranged between each fixed frame and the corresponding floating frame; and the upper end of each floating frame is provided with the positioning pin module and the guide pin module, wherein the positioning pin module is used for performing positioning on the cargo, and the guide pin module is used for guiding the cargo.The flexible docking and rapid positioning system realizes flexible fetching and feeding of a product, and can realize accurate positioning of the product after the product reaches a station, so thatthe automatic docking need is 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 flexible docking and rapid positioning system. 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 ...

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 Long debugging period and relatively low system reliability
