Device for packaging rear end of disc-shape chip

Abstract

The invention provides a device for packaging the rear end of a disc-shape chip. By means of the device for packaging the rear end of the disc-shape chip, winding of a protective belt on the disc-shape chip and attaching of adhesive tape and sealing in the joint position of the protective belt can be achieved automatically; working efficiency is improved greatly; the manpower cost is lowered; moreover, the degree of tightness of the wound protective belt is consistent, and reliability is high; and attaching positions of the adhesive tape are uniform, and more orderliness and beauty are achieved. The device for packaging the rear end of the disc-shape chip comprises a support platform, a protective belt winding unit and an adhesive tape attaching unit which are arranged on a base. The support platform is used for placing the disc-shape chip. The protective belt winding unit is used for feeding the protective belt and winding the protective belt on the disc-shape chip placed on the support platform. The adhesive tape attaching unit is used for attaching adhesive tape on the protective belt and conducting sealing in the joint position of the protective belt after the protective belt is wound on the disc-shape chip by the protective belt winding unit.

Description

technical field [0001] The invention relates to the technical field of chip back-end packaging equipment, in particular to a disc-shaped chip back-end packaging device. Background technique [0002] At present, after the chips of the integrated circuit are braided into rolls, it is usually necessary to wind the protective tape and seal the joints of the protective tape. After a week, stick masking tape on the joints of the protective tape. [0003] The protection tape can better protect the chip and prevent damage to the chip. In addition, the protection tape can also prevent chip damage that may occur during the transportation of the chip. However, the original chip back-end packaging operation mode has the following disadvantages: [0004] The winding of the existing protective tape and adhesive tape is done manually, which has the problems of high labor intensity, low production efficiency, and high labor cost, and manual operation, once the protective tape or adhesive ...

AI Technical Summary

Problems solved by technology

[0004] The winding of the existing protective tape and adhesive tape is done manually, which has the problems of high labor intensity, low production efficiency, and high labor cost, and manual operation, once the protective tape or adhesive tape is wound negligently, the chip will be easily damaged; in addition Using manual operation, there are differences in the tightness of the winding. If it is too loose: the protective tape will fall apart and will not provide protection. If it is too tight: it will crush the chips in the braid. At the same time, there are differences in the sticking position of the masking tape. Aesthetically poor

[0005] There is also a Chinese invention patent with publication number CN102991773A that provides a winding device for chip packaging of integrated circuits. Although it can automatically realize the winding of protective tapes and sponge strips, it only discloses the use of a glue applicator, a winding For equipment such as machine, the specific structure of the equipment has not been disclosed, and it has no practical reference value
