Description

Technical Field

The traditional method requires manual pressing to install the heat sink on the PCB, which has slow installation speed and low efficiency. The operator will feel tired after pressing for a long time, and because there is no positioning device, when pressing the pressure column on the heat sink, it will cause damage to the components on the PCBA.

[0003] The existing installation device requires high proficiency of the operator, and professional training is required before the operator can take up the post. The employees have many operating movements, the installation speed is slow, the efficiency is low, and the operation fatigue occurs after pressing for a long time (each installation takes about 25 seconds). When pressing the buckle on the heat sink, there is no positioning device in manual operation, which may cause the hidden danger of damage to the components on the PCBA. When the workers install the heat sink, the sweat on their hands contaminates the metal surface and causes oxidation. Therefore, in view of the above problems, a device for quickly installing the heat sink on the front of the TV board is proposed. Utility Model Content
