[0002] CPU of the server needs to be circulated, and is brought to the installation personnel one by one in the server installation process, so as to facilitate the installation personnel to obtain. The installation personnel installs the obtained CPU to the server. The CPU needs to be handled gently during the circulation process, and is prevented from vibration, dust and moisture, which puts forward higher requirements for the CPU circulation fixture. UTILITY MODEL CONTENTS

[0003] The utility model solves the technical problem of providing a CPU circulation fixture, which facilitates the CPU to be handled gently, and prevents vibration, dust and moisture.

[0004] To solve the above technical problem, the utility model provides the following technical scheme: a CPU circulation fixture, comprising a fixture bottom plate, a cover plate hingedly connected to the fixture bottom plate, a product positioning groove is formed in the fixture bottom plate, the cover plate can be covered on the product positioning groove, a sponge is glued to the bottom of the product positioning groove, the sponge is in a frame shape, and the middle part is hollow; finger accommodation grooves are arranged on the two sides of the product positioning groove, and the bottom surface height of the finger accommodation grooves is lower than or equal to the height of the sponge; a vacuum adsorption device is arranged on the cover plate, and the vacuum adsorption device is arranged correspondingly to the product positioning groove.

[0005] According to the above technical scheme, the worker places the CPU in the product positioning groove. When placing, the worker holds the CPU on both sides with fingers, and then places the CPU into the product positioning groove. The finger accommodation grooves accommodate the fingers holding the CPU on both sides, so as to facilitate the worker to place the CPU gently. The CPU in the product positioning groove is in contact with the sponge, and the sponge supports the CPU. Then, the cover plate is covered on the product positioning groove. In this way, when the circulation fixture is jolted or vibrated during the circulation process, the sponge can reduce the vibration of the CPU, and the cover plate plays a dustproof and moistureproof role on the CPU.

[0006] After the circulation fixture reaches the predetermined station, the worker uses the vacuum adsorption device to adsorb the CPU in the product positioning groove, and then opens the cover plate. In this way, the worker can conveniently take the CPU.
