Abstract

The invention discloses an anti-skid system and adjustment method of an AGV trolley. Each drive wheel is provided with one or more active control spring units, and each active control spring unit includes a driving motor, a main fixing component, a coupling, a lead screw, a spring, a sliding block and a pressure sensor. The sliding blocks are connected with the lead screws though threads, the springs are arranged on the lead screws in a sleeving mode, the upper parts of the springs are connected with the bottoms of the sliding blocks, the lower parts of the springs are connected with connecting pieces, and the springs apply force on the driving wheels through the connecting pieces. The pressure sensors are arranged on the joints of the springs and the connecting pieces and connected with an industrial personal computer in a communication mode. The driving motors are fixed to the main fixing components and are controlled by the industrial personal computer to drive the lead screws through the couplings to control the sliding blocks to move up and down to adjust the expansion and contraction quantity of the springs. The anti-skid system and adjustment method of the AGV trolley is provided with the active control spring units, and actively controls the positive pressure between the driving wheels and the ground to effectively prevent driving wheels of the AGV trolley from skidding.

Description

technical field [0001] The invention relates to the technical field of AGVs, in particular to an anti-skid system and an anti-skid adjustment method for an AGV trolley. Background technique [0002] AGV is the abbreviation of (Automated Guided Vehicle), which means "automatic guided vehicle". AGV generally adopts the structure of two driving wheels in the middle of the bottom plate and four omnidirectional load-bearing wheels at the front and rear of the bottom plate. During the movement of the AGV, if the ground is uneven, the driving wheels will have the problem of hanging and slipping. [0003] Traditional AGV cars will install suspension springs above the driving wheels, and the springs are generally in a compressed state. When the driving wheel enters the pit, the compressed spring will make the driving wheel touch the ground due to elongation, effectively preventing the driving wheel from hanging and slipping. However, after installing the suspension spring, due to t...
