Automatic CPU pick-place module provided with lever propping-pressing device

Abstract

The invention discloses an automatic CPU pick-place module provided with a lever propping-pressing device. The automatic CPU pick-place module comprises a rack, a slide connecting base, a first drivedevice, a CPU clamping assembly, an adaptive positioning device and a locking device, wherein relative position between a CPU and a CPU installation base can be adaptively adjusted during CPU installation, so that the CPU fits the CPU installation base completely, propping-pressing force is perpendicular to the plane of the CPU all along during pressure loading, and contact force of the CPU and the CPU installation base is uniform. The lever propping-pressing device of the automatic CPU pick-place module adopts the principle of the equal armed lever, when the CPU clamping assembly inclines, two force guide posts located on a transitional connecting plate and taking the symmetry axis of the transitional connecting plate as the center prop and press the CPU clamping assembly all along, a pressure head assembly props and presses the center of the transitional connecting plate, so that force of the two force guide posts applied to the CPU clamping assembly is always the same, the propping-pressing force is always perpendicular to the CPU, and accordingly, the contact force of the CPU and the CPU installation base is always uniform.

Description

【Technical field】 [0001] This application is a divisional application of a patent application with an application date of August 31, 2016, an application number of 201610796652.X, and an invention title of "a CPU automatic pick-and-place module and CPU automatic pick-and-place method". 【Background technique】 [0002] The computer motherboard needs to be tested before leaving the factory. The CPU needs to be installed on the CPU mounting seat on the motherboard. In the traditional testing process, the CPU needs to be manually installed on the motherboard and then tested. The traditional manual work method is inefficient. ; Along with the raising of automation level, there are some equipments that can automatically install CPU on the CPU mounting seat, and Chinese invention patent discloses a kind of CPU automatic pick-and-place machine (public number: CN103729277B) that CPU can be automatically put into place for computer motherboard test. Install it on the motherboard, and t...

Problems solved by technology

[0004] 1. The number of CPU contacts is as high as 3647. When working, it is necessary to make good contact between the contacts of each CPU and the contacts on the CPU mounting base, that is, the bottom surface of the CPU is completely consistent with the CPU mounting base. However, in reality, the motherboard (CPU mounting base) ) is impossible to maintain a level of 100%, it may be tilted at an angle, which requires the CPU pick and place module to be able to adaptively adjust the precise positioning according to the actual position of the motherboard (CPU mounting seat), if some points are not touched, it will not be normal Work;
