Description

Technical Field

[0001] The utility model relates to the technical field of narrow space handling equipment, in particular to a double-stroke translation platform. Background Art

[0002] In narrow spaces (such as glove boxes, hot rooms, and other confined spaces), when transporting various workpieces, in order to ensure the safety of operators, they are gradually replaced by automated handling devices.

[0003] Currently, there are two main methods used in hot rooms and glove boxes:

[0004] Put people's hands in to carry out the transportation;

[0005] Use master-slave manipulators for handling.

[0006] The existing problems are: the work efficiency is low and the operation is inconvenient when people reach in to carry out the work by hand; the cost of the robot is too high and it is not suitable for working scenes with shorter heights.

[0007] Therefore, it is necessary to develop a double-stroke translation stage to solve the above problems. Summary of the invention

[0008] The purpose of the utility model is to design a double-stroke translation platform in order to solve the above problems.

[0009] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0010] Double-travel translation stage, including:

[0011] Base plate;

[0012] The servo motor is mounted on the first end of the base plate;

[0013] Ball screw; the power output end of the servo motor is connected to the first end of the screw of the ball screw;

[0014] A first upper cover; the first upper cover is movably mounted on the bottom plate through at least one first guide rail assembly; a screw nut of the ball screw is connected to a first end of the first upper cover;

[0015] The second upper cover is movably mounted on the first upper cover by at least one second guide rail assembly;

[0016] A first chain and a first sprocket; the first sprocket is rotatably mounted on the first end of the first upper cover, the first end of the first chain is fixed to the second end of the bottom plate, and the second end of the first chain is connected to the second end of the second upper cover after passing around the first sprocket meshed with the first chain; the plane where the first chain is located, the plane where the first sprocket is located, and the ball screw are parallel to each other;

[0017] The second chain and the second sprocket are rotatably mounted on the second end of the first upper cover, the first end of the second chain is fixed to the first end of the base plate, and the second end of the second chain is connected to the first end of the second upper cover after passing around the second sprocket meshing therewith.

[0018] The beneficial effects of the utility model are:

[0019] The present application utilizes a servo motor to drive a ball screw, the ball screw drives a first cover plate, and the first cover plate drives the second cover plate to move forward and backward simultaneously through two sets of chains and sprockets, thereby achieving a double-stroke structure with a single screw stroke. The overall height of the present application is relatively short, and it can be adapted to low working scenes; and it is transported through mechanical action, with high efficiency, and therefore only uses a servo motor and a cover plate for actuation, with a relatively low cost.
