Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of RGV positioning, in particular to an RGV trolley running positioning mechanism. Background Art
[0002] RGV trolley is the abbreviation of Rail Guided Vehicle, also known as rail shuttle trolley, which is commonly used in product processing production lines, high-density storage warehouses, etc. At present, the commonly used positioning systems for RGV trolleys include RFID positioning, QR code positioning, etc. Although the above solutions can achieve the positioning of the RGV trolley, the positioning accuracy is relatively low. The processing production lines of some products have higher processing accuracy, and the corresponding processes need to ensure the accuracy of the position. At the same time, since some tooling and workpieces need to be moved together to the processing equipment for processing, the tooling cannot be fixed on the RGV trolley, which makes it easy for the tooling to be displaced during the movement of the RGV trolley. Therefore, in order to ensure processing accuracy, there is an urgent need for a positioning mechanism that can position the tooling. Utility Model Content
[0003] The utility model aims to solve the technical problems existing in the prior art, and particularly innovatively proposes an RGV trolley operation positioning mechanism, which can position the workpiece after arriving at each processing station and can correct a certain degree of offset to ensure processing accuracy.
[0004] In order to achieve the above-mentioned purpose, the utility model provides an RGV trolley operation positioning mechanism, including a plurality of groups of tooling positioning structures arranged in sequence at each processing area along the moving direction of the RGV trolley, each group of tooling positioning structures includes a plurality of positioning seats arranged on the ground on both sides of the track of the RGV trolley, and the lifting platform of the RGV trolley is provided with tooling for placing workpieces, and the left and right sides of the tooling extend outside the RGV trolley, and the bottom side of the part of the tooling extending outside the RGV trolley is provided with a downwardly extending lower positioning column, the number and spacing of the lower positioning columns are arranged corresponding to the positioning seats of each group of tooling positioning structures, and the bottom end of the lower positioning column is recessed with an adjustment groove for accommodating the top of the positioning seat.
[0005] In the above solution, the positioning seats on both sides are symmetrically arranged and arranged in a matrix. The arrangement is reasonable and can avoid the occurrence of front and rear tilting as much as possible.
[0006] In the above solution, the top of each positioning seat is conical, and the adjustment groove is also a conical groove that is smaller at the top and larger at the bottom, which can be automatically aligned and fine-tuned.
[0007] In the above solution: the taper of the top of the positioning seat is 60°.
[0008] In summary, the beneficial effects of the present invention are as follows: the positioning seat set on the ground is stably installed, does not move, can serve as a placement reference point, and has a simple structure. The conical top can automatically return to its original position when the tooling is lowered if the tooling has an offset within a certain range, adjusting the position of the tooling, thereby ensuring the positioning of the workpiece, avoiding the tooling and workpiece from offsetting during movement, ensuring accuracy, and being suitable for situations where high accuracy is required.

[0013] The present invention will be further described below with reference to the following embodiments and accompanying drawings:
[0014] like Figures 1 to 4 As shown, an RGV trolley positioning mechanism includes multiple sets of tooling positioning structures arranged in sequence at each processing area along the movement direction of the RGV trolley 1. Each set of tooling positioning structures includes multiple positioning seats 3 installed on the ground on both sides of the track 1a of the RGV trolley 1. The positioning seats 3 on both sides are symmetrically arranged in a matrix. This reasonable arrangement can minimize the occurrence of forward and backward tilting.
[0015] The lifting platform of the RGV trolley 1 is equipped with a tool 2 for placing workpieces, and the left and right sides of the tool 2 extend outside the RGV trolley 1. The bottom side of the part of the tool 2 that extends outside the RGV trolley 1 is provided with downwardly extending lower positioning columns 4. The number and spacing of the lower positioning columns 4 are set to correspond to the positioning seats 3 of each set of tool positioning structure. The bottom end of the lower positioning columns 4 is recessed with an adjustment groove 4a for accommodating the top of the positioning seat 3. The top of each positioning seat 3 is conical, and its taper is 60°. The adjustment groove 4a is also a conical groove with a smaller top and a larger bottom, which can automatically align and perform fine adjustments, which is convenient and quick.
[0016] The traditional RGV trolley is mainly composed of a frame, driving wheels, follower wheels, front and rear bumpers, tooling, communication system, electrical system and various cover plates to ensure that it can run stably and efficiently on the track. These are all existing technologies and will not be described here. When the RGV trolley 1 moves to the corresponding workstation through its control system, the tooling is dropped by the lifting platform. When it drops, the adjustment groove 4a on the bottom of the tooling is aligned with the conical top of the positioning seat 3, and the offset can be automatically corrected through the conical top, and the positioning accuracy can reach ±1mm.
