Flexible sliding table device controlled by PLC closed loop

Abstract

The invention discloses a flexible sliding table device controlled by a PLC closed loop. The flexible sliding table device comprises a sliding part, a drive part, a transmission part and a PLC control part, wherein the sliding part comprises two linear guide rails which are arranged in a direction of movement of a quartz boat seat, and the two linear guide rails are separately positioned on guide rail mounting plates at left and right sides; a slide block for driving the quartz boat seat to move is arranged on the linear guide rails in a sliding mode, and is driven by the drive part; the drive part comprises a step motor and a speed reducer; the transmission part comprises a left drive wheel assembly, a right drive wheel assembly and two connecting rods; the connecting rods are driven by the drive part to further drive the left drive wheel assembly and the right drive wheel assembly; the left drive wheel assembly and the right drive wheel assembly separately drive a left slide block mounting plate and a right slide block mounting plate as well as the slide bock on the two mounting plates to move along the linear guide rails through a synchronous belt; the quartz boat seat is mounted on the slide block; and the PLC control part is used for controlling the drive part. The flexible sliding table device has the advantages of being simple and compact in structure, simple and convenient to operate, high in control precision, good in reliability and the like.

Description

technical field [0001] The invention mainly relates to the field of diffusion furnaces, in particular to a telescopic sliding table device mainly suitable for diffusion furnaces controlled by a PLC closed loop. Background technique [0002] The loading and unloading workbench of the existing diffusion furnace consists of a support frame, a linear guide rail fixed on the support frame, a slider set on the linear guide rail, a bracket fixing seat fixed above the slider, and a stepper fixed on the support frame. The motor, the transmission belt connecting the bracket fixing seat and the stepping motor, the quartz boat bracket fixed on the bracket fixing seat, the limit sensor fixed on the bracket fixing seat and the support frame, and the receiving limit sensor are composed. When working, the bracket moves to the end of the guide rail, and the limit position is controlled by the limit sensor. After the raw materials are installed, they will be returned to the furnace body, whil...

AI Technical Summary

Problems solved by technology

It can be seen that the loading and unloading workbench protrudes from the framework of the clean bench and is fixed, resulting in a large overall structural size of the diffusion furnace, occupying a lot of space on site, and may cause safety accidents due to tripping during on-site operation. Serious threats to the safety of workers, equipment, raw materials and products
