Description

Technical Field

[0001] The utility model belongs to the technical field of BLU crimping, and specifically relates to a BLU automatic crimping structure. Background Art

[0002] The backlight unit (BLU) is usually used to provide backlight in liquid crystal displays (LCDs). It is mainly composed of black and white plastic, brightening film, diffusion film, etc. LCD display is a passive light-emitting display technology. It needs to rely on the backlight module to convert LED point light source or CCFL line light source into a uniformly distributed surface light source to provide brightness for the LCD panel so that its graphic information can be seen by the human eye.

[0003] The PIN angle in the backlight unit is a key part for electrical connection with other circuits or components. By crimping, a solid electrical connection can be established between the PIN angle and the corresponding connector or circuit board, so that the backlight unit can work properly.

[0004] The PIN corners in existing backlight modules are usually crimped manually. Manual crimping requires operators to perform it one by one. Compared with automated crimping, it is slower and has low production efficiency. During the manual crimping process, due to interference from human factors, such as operating proficiency and distraction, the crimping quality may be unstable, such as poor crimping, excessive or insufficient crimping, etc. Manual crimping requires operators to directly contact the backlight module and the crimping tool. Improper operation may cause hand injuries and may pose a safety risk.

[0005] In view of this, this application is hereby filed. Utility Model Content
