Description

Technical Field

[0001] The utility model relates to the technical field of RGV trolleys, in particular to a high-precision secondary positioning mechanism for an RGV trolley. Background Art

[0002] RGV is the abbreviation of rail-guided vehicle, also known as rail-guided shuttle vehicle. RGV can be used in warehouses with various high-density storage methods. Currently, common RGV positioning systems include RFID positioning, QR code positioning, and other methods.

[0003] Chinese patent application number (CN207090262U) discloses an RGV trolley that combines multiple positioning methods. This patent application determines the travel distance of the RGV trolley based on the encoder, and then locates the position of the RGV trolley in conjunction with the QR code positioning method. Although the above scheme can achieve the positioning of the RGV trolley, its positioning accuracy is low. The workpiece carried by the RGV trolley sometimes needs to be fixed on the RGV trolley for processing. When the workpiece runs to a fixed position for processing, the positioning accuracy requirement is very high. The existing positioning method cannot meet this demand, resulting in a large deviation every time the RGV trolley reaches this fixed position, resulting in the inability to guarantee the processing accuracy of the customer's workpiece, and even causing the product to be scrapped, affecting the normal operation of the entire production line. Therefore, the utility model provides a high-precision secondary positioning mechanism for the RGV trolley to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of the utility model is to provide a high-precision secondary positioning mechanism for an RGV trolley to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A high-precision secondary positioning mechanism for an RGV trolley includes a positioning system, a lubrication system, and a detection mechanism. The positioning system consists of a positioning rail and a positioning guide groove. Lubrication system pipelines are provided at both ends of the positioning system for automatic oil filling. A group of pressure sensors are provided at the end of the positioning system as a detection mechanism. The lubrication system consists of a group of oil pump units connected to oil pipes for automatic oil filling and lubrication. The detection mechanism relies on a group of pressure sensors to detect whether the positioning system is in place.

[0007] As a further solution of the present invention, a positioning rail fixing plate is provided at the lower end of the positioning rail, and mounting holes are provided at the four corners of the positioning rail fixing plate, so that the positioning rail fixing plate can be easily installed and fixed through the provided mounting holes.

[0008] As a further solution of the present invention, positioning holes are symmetrically provided on the positioning guide groove fixing seat.

[0009] Compared with the existing technology, the beneficial effects of the present invention are: when the present invention is used, the RGV trolley, through the coordinated use of the positioning system, lubrication system and detection mechanism, facilitates more accurate delivery of the workpiece to the position, eliminates manual operation, saves a lot of labor, improves production efficiency, can accurately locate the docking function, realize precise docking, and ensure accurate operation, thereby realizing production automation and efficient operation.
