Abstract

The invention relates to the technical field of chip packaging, and discloses a direct-current direct-drive type driving chip with multiple packaging forms and a packaging device and method. Stable and ordered blanking is completed through a simple mechanical structure by arranging an electric telescopic rod and the like, rapid heat fusion packaging is achieved by adopting a fluorescence labeling mode in cooperation with a hot melting gun, different chip packaging shells can be selected in a self-adaptive manner while precise packaging is realized, and the packaging efficiency is improved. Two clamping blocks at the corresponding positions are driven to rotate with the corresponding rotating shafts as the axes through the arrangement of clamping air cylinders and the like, then the clamping blocks on the two sides clamp the two sides of a to-be-packaged chip, the packaging stability is further improved, the displacement influence on the to-be-packaged chip caused by the operation of a conveying belt is avoided, a pushing plate pushes the corresponding to-be-packaged chip into a defective product groove through the operation of a material returning air cylinder, defective product collection is completed, and the packaging effect of an assembly line is ensured.

Description

technical field [0001] The invention relates to the technical field of chip packaging, in particular to a direct-current direct drive driver chip in a multi-package form, as well as a packaging device and method. Background technique [0002] Chip packaging is the shell for installing semiconductor integrated circuit chips, which has the functions of placing, fixing, sealing, protecting chips and enhancing electrothermal performance. Chip packaging is a bridge between the internal world of the chip and the external circuit. The contacts of the chip are connected to the pins of the package shell with wires, and the pins are connected to other devices through the wires on the printed board; the package is integrated with the CPU and other LSIs. The circuit all plays an important role, the number of pins increases, the pin spacing is reduced, the weight is reduced, the reliability is improved, and it is more convenient to use. [0003] In the prior art, the common LED driver c...
