Shading adhesive tape flexible edge covering device and method

Abstract

The invention discloses a shading adhesive tape flexible edge covering device and method. The device comprises a device platform, the device platform is provided with a guide plate and a plurality of rollers which are sequentially arranged in the product feeding direction, and the rollers have different inclination angles respectively; the guide plate is used for downwards pressing the suspended part of the shading adhesive tape for an angle when the product with the shading adhesive tape attached to the front surface is fed; the rollers comprise a plurality of guide rollers and a pair of edge covering rollers which are sequentially arranged in the product feeding direction, the guide rollers are used for guiding the suspended part of the shading adhesive tape to be bent downwards step by step, and the edge covering rollers are used for tightly pressing the shading adhesive tape to the side face and the back face of the product; and in the plurality of rollers, at least the edge covering rollers are provided with elastic surfaces. According to the device, the shading adhesive tape is guided and bent through the multiple rollers with different inclination angles, the edge covering quality is guaranteed by arranging at least the elastic surfaces on the edge covering rollers, and the production efficiency and the yield of shading adhesive tape edge covering are improved.

Description

technical field [0001] The invention relates to the technical field of tape wrapping, in particular to a flexible wrapping device and method for light-shielding tape. Background technique [0002] In the current display panel assembly scene, there is a process of wrapping a black light-shielding tape around the display panel product. The function of this light-shielding tape is to prevent light leakage from the edge of the display panel and to strengthen the connection between the display panel and the backlight panel. The connection between them makes the combination stronger. [0003] At present, for this process, most factories rely on manual work to complete the edge wrapping of the light-shielding tape. The one-time pass rate of manual operation is 70-90%. The pass rate is limited by the proficiency of the workers, and the efficiency is low, about 1 tablets / minute / person, unable to form a stable and continuous output. There are also very few display module manufacture...

Problems solved by technology

[0003] At present, for this process, most factories rely on manual work to complete the edge wrapping of the light-shielding tape. The one-time pass rate of manual operation is 70-90%. The pass rate is limited by the proficiency of the workers, and the efficiency is low, about 1 piece / minute / person, unable to form a stable and continuous output

There are also very few display module manufacturers using equipment attachment, but there are problems of high equipment cost and low yield

[0004] The hemming equipment of prior art, as figure 1 and figure 2 As shown, there are pairs of wrapping rollers 11, which mainly rely on the rollers 11 to press down to bend the light-shielding tape 12, and then feed the rollers 11 to the center of the product 13 to complete the wrapping process of the light-shielding tape 12. However, once the product 13 If the position is skewed, the pressing process of the roller 11 will cause poor attachment or directly crush the product 13
