Online digital automatic glue dispensing machine for thermal grease

Abstract

The invention discloses an online digital automatic glue dispensing machine for thermal grease. The online digital automatic glue dispensing machine comprises a machine body, wherein an online conveying mechanism, a glue dispensing valve and an online detection mechanism are arranged on the machine body; the online conveying mechanism is used for connecting a front station with a rear station; the glue dispensing valve corresponds to the online conveying mechanism; the glue dispensing valve adopts a precise screw rod extrusion mode so that the glue dispensing precision is ensured; gantry brackets are arranged at both the inlet end and the outlet end of the online conveying mechanism; the glue dispensing valve and the online detection mechanism are synchronously mounted on the gantry brackets through an X-direction moving shaft, a Y-direction moving shaft and a Z-direction moving shaft; the online detection mechanism comprises a CCD image device, a two-dimensional code scanning device and a laser height measuring device. Due to online glue dispensing, a transferring procedure is eliminated, the working intensity is low, the operation time is shortened, the efficiency is improved, and due to online detection, the glue dispensing efficiency is greatly improved, and the product percent of pass is effectively ensured.

Description

technical field [0001] The invention relates to a dispensing device, in particular to an online digital automatic dispensing machine for heat dissipation paste. Background technique [0002] The heat transfer between the heat sink and the CPU is mainly through conduction, which is achieved through direct contact between the heat sink and the CPU. The significance of heat dissipation paste is to fill the gap between the two to make the contact more complete. If the heat dissipation paste is used excessively, a heat dissipation paste layer is formed between the CPU and the heat sink, and the heat dissipation path becomes CPU--heat dissipation paste--heat sink , the thermal conductivity of heat dissipation paste is about 1-2W / (mK), while the aluminum alloy heat sink is above 200W / (mK). In this case, heat dissipation paste becomes a factor that hinders heat transfer, so the amount of heat dissipation paste must be applied , just apply a thin layer on the CPU core and that's it....

AI Technical Summary

Problems solved by technology

[0003] In the prior art, since the application of heat dissipation paste needs to be carried out in different steps, that is, after the processing of the CPU is completed, it is transferred to the next process for application of heat dissipation paste. The work efficiency of the sub-processes is low, and the integrity and thickness of the heat dissipation paste coating are difficult to guarantee. , it needs to pass the inspection of subsequent multi-process procedures to confirm whether it is qualified, so the efficiency is low
