PIN press-fitting device

Abstract

The invention discloses a PIN press-fitting device. The PIN press-fitting device comprises a turnover mechanism and a pin bin which are arranged on a machine table, a pin feeding mechanism and a press-fitting mechanism are sequentially arranged in the rotating direction of the turnover mechanism, the turnover mechanism comprises a rotary disc, a plurality of product jigs carrying cooling fins areevenly distributed on the edge of the rotary disc, and the pin feeding mechanism comprises a working part capable of being converted from the horizontal direction to the vertical direction and a feeding unit arranged on the working part; the press-fitting mechanism comprises a press-fitting air cylinder and a group of press-fitting ejector pins arranged on the press-fitting air cylinder, and an auxiliary positioning mechanism used for assisting in positioning the cooling fins on the product jigs is arranged at the position, corresponding to the pin feeding mechanism, below the rotary disc; andthe PIN press-fitting device further comprises a stripping mechanism used for conveniently separating the press-fitted cooling fins from the product jigs. According to the PIN press-fitting device, automatic implantation and automatic press-fitting of PINs in production of the cooling fins are realized, the automation degree is high, compared with a traditional manual press-fitting mode and PIN press-fitting machine, the technical scheme has the advantages that the press-fitting efficiency of the PINs is greatly improved, and labor force is liberated.

Description

technical field [0001] The invention relates to the field of radiator production and manufacturing, in particular to a PIN needle press-fitting device. Background technique [0002] The heat sink is a device for quickly dissipating heat from the heat-prone electronic components in the power supply. It is mostly made of aluminum alloy, brass or bronze into plates, sheets, and multi-sheets. For example, the CPU central processing unit of a computer needs to use a considerable the heat sink. During the production process of the heat sink, it is necessary to assemble a PIN pin on the heat sink, and the PIN pin is a small metal pin. The steps form a cross-shaped PIN needle. The lengths of the two ends of the steps of the PIN needle are not equal. Generally, the end inserted into the heat sink is relatively short. At present, most of the PIN needles inserted into the heat sink are pressed. The method of mounting realizes the bump riveting to complete the fixing of the PIN pin an...
