Claim Text:
1. A loading and unloading device for a quartz reaction tube of a semiconductor diffusion equipment, which is used in combination with a lifting device having an interface flange attachable to the quartz reaction tube, including: a translation drive structure including a support platform composed of an upper support plate and a lower support plate stacked up and down, and a handle connected to the support platform; wherein the lower support plate is fixedly connected to a group of height-adjustable rollers; a linear guide rail mounted on the upper support plate; a bracket positioned on the linear guide rail; an auxiliary support structure working in conjunction with the bracket to detachably fix the quartz reaction tube to the bracket, which includes a first interface unit to be connected to the bracket and a second interface unit to be connected to a bottom assembly of the quartz reaction tube, wherein the quartz reaction tube includes an inner tube and an outer tube; the second interface unit includes at least an inner tube interface unit to be connected to the bottom assembly of the inner tube of the quartz reaction tube and/or at least an outer tube interface unit to be connected to the bottom assembly of the outer tube of the quartz reaction tub; wherein during the loading procedure, a front end of the translation drive structure is docked with doorframes of the semiconductor diffusion equipment by a fixing structure, and the quartz reaction tube is docked with the interface flange of the lifting device by horizontally moving the bracket along the linear guide rail.
