Walking mechanism capable of actively steering and screen printer

Abstract

The invention discloses a walking mechanism capable of actively steering and a screen printer. The walking mechanism capable of actively steering comprises a walking mechanism body, a steering induction device for judging steering information of the walking mechanism body, walking wheels, drive devices for driving the walking wheels to rotate, a PLC (Programmable Logic Controller) device for controlling working conditions of the drive devices, and a lifting device for controlling the walking mechanism body to lift up and down, wherein the walking wheels are arranged on the bottom part of the walking mechanism body and are connected with the drive devices; and the lifting device and the steering induction device are electrically connected with the PLC device. The walking mechanism capable of actively steering also comprises a guiding belt, wherein a guiding sensor for monitoring a relative position between the walking mechanism body and the guiding belt is arranged on the walking mechanism body, and is electrically connected with the PLC device, so that the walking mechanism can actively steer according to a specific route without the need for an extra rotary table mechanism, the operation space of the equipment is saved, and the equipment cost is reduced.

Description

technical field [0001] The invention relates to the technical field of screen printing, in particular to an actively steering traveling mechanism and a screen printing machine. Background technique [0002] Due to the large horizontal area of ​​the existing screen printing machine, a relatively large operating space is required. Therefore, when working with the printing platen, the printing machine walks on the printing platen. The existing screen printing machine has The limitations of the following aspects: Since the screen printing machine runs on the printing platen, the accuracy of the track guide of the printing platen determines the accuracy of the screen printing machine, so the screen printing machine has a large impact on the printing platen and the printing table. The precision of the plate rail guide is very high; it is necessary to install additional guide devices such as walking guide rails and walking guide wheels, which increases the cost of the equipment; th...

[0002] Due to the large horizontal area of ​​the existing screen printing machine, a relatively large operating space is required. Therefore, when working with the printing platen, the printing machine walks on the printing platen. The existing screen printing machine has The limitations of the following aspects: Since the screen printing machine runs on the printing platen, the accuracy of the track guide of the printing platen determines the accuracy of the screen printing machine, so the screen printing machine has a large impact on the printing platen and the printing table. The precision of the plate rail guide is very high; it is necessary to install additional guide devices such as walking guide rails and walking guide wheels, which increases the cost of the equipment; the weight of the screen printing machine ranges from 100KG to 600KG, and the printing table needs to bear the weight during work. The weight of one or more machines, therefore, has higher requirements on the load-bearing of the printing platen, which usually requires stronger materials and more complex structures than ordinary platens, thus increasing the complexity and cost of the equipment; screen printing In the traveling mechanism of the machine, since the driving wheels are on the same driving shaft, the screen printing machine can only move forward and backward. If it needs to turn and change lanes, it needs to use the turntable mechanism, which requires a large operating space and cost investment.
