Problems solved by technology

But when the test equipment has the needs of upper and lower pallets, it is difficult to find suitable loading and unloading equipment
Especially in assembly or maintenance work, high-frequency flipping of test equipment is required, which cannot be done by ordinary loading and unloading equipment
[0003] The rotating trolleys currently on the market can only meet a single rotation requirement, and when loading or unloading test equipment on or off the rotating trolley, only manual or some unconventional tools can be relied on, which poses a high safety risk
Moreover, due to the heavy weight of the test equipment, it is also very difficult to assemble

Abstract

The invention discloses a rotating trolley, which comprises: a lifting driving mechanism arranged on a chassis for lifting and lowering the rotating driving mechanism; a rotating driving mechanism arranged on the lifting driving mechanism for horizontally rotating the clamping mechanism; The holding mechanism is provided with a fork-shaped arm, which is used to clamp the test equipment from the left and right sides. The center of the fork-shaped arm is provided with a support shaft, and the support shaft is connected to the rotating part of the rotary drive mechanism; and the support mechanism is used to support the test equipment. support. The invention can conveniently load and transport the test equipment, can reduce the requirements for factory equipment and the difficulty of loading, and save the disassembly and assembly work of the test equipment and the rotating trolley.

Description

technical field [0001] The invention relates to the technical field of loading and unloading equipment, and more particularly, relates to a rotary trolley that can be used for loading and unloading semiconductor testing equipment. Background technique [0002] In the field of semiconductor automated test (ATE), test equipment is required for testing at many process nodes. Since the test equipment is generally large in size and weighs up to several hundred kilograms, special lifting equipment is required for its turnover and transportation. But when the test equipment has the needs of upper and lower pallets, it is difficult to find suitable loading and unloading equipment. Especially during assembly or maintenance work, high-frequency flipping of test equipment is required, which cannot be done with ordinary handling equipment. [0003] The rotating trolleys currently on the market can only meet a single rotation requirement, and when loading or unloading test equipment on...
