Abstract

The invention discloses a chip removing device which is used for removing a chip attached on a display panel, and relates to the field of display panel manufacture. The device comprises a heating head used for heating the chip, wherein the heating head comprises at least two inner side surfaces; the two inner side surfaces are arranged in an adjacent or opposite manner, and are respectively used for being in contact with two adjacent or opposite outer side surfaces of the chip. The device further comprises a driving mechanism which is used for driving the heating head to move in a preset range, and when the heating head moves, the chip can be separated from the display panel. According to the chip removing device, the shape of the heating head is improved, the contact area of the chip and the high temperature heating head is enlarged, the chip is heated uniformly, and burn and solidification of aeolotropic conductive adhesive due to overhigh local temperature are avoided. Besides, the driving mechanism is adopted to achieve the purpose of accurately controlling the moving distance of the heating head, and scald by a polarizer when the display panel is manually displaced to remove the chip is avoided.

Description

technical field [0001] The invention relates to the field of manufacturing display panels, in particular to a chip removing device. Background technique [0002] During the manufacturing process of the display panel, it is necessary to attach a drive chip (Drive Integrated Circuit) to the display panel through an anisotropic conductive glue (ACF), so as to realize the display function of the display panel. However, in the actual production process, there may be defects such as dislocation and damage in the attachment of the chip. At this time, the chip needs to be removed for repair. [0003] The existing chip removal method is to heat the chip to soften the anisotropic conductive adhesive in the corresponding part, and then manually push the display panel to remove the chip. Due to unstable manual force, it is easy to cause the display panel to move excessively, causing the polarizer to come into contact with the high-temperature heating head and cause burns. [0004] In ...
