Lamp strip press-fit device

Abstract

The invention provides a lamp strip press-fit device. The device comprises a box body and a press-fit structure which is arranged on the box body and used for pressing a lamp strip; the press-fit structure comprises a vertical fixing plate, an inverted-L-shaped plate connected with the rear side of the vertical fixing plate, a longitudinal drive mechanism connected with the front side of the vertical fixing plate and a transverse drive mechanism connected with the side edge of the inverted-L-shaped plate, the press-fit structure further comprises a horizontal pressing plate arranged on the lower side of the transverse drive mechanism and a side pressing plate arranged on the side edge of the transverse drive mechanism, and a sliding structure enabling the press-fit structure to move between the to-be-pressed state and the press-fit state is connected between the press-fit structure and the box body and is driven through the horizontal driving mechanism. The device is connected with a dual-starting and resetting button through a PLC, the horizontal drive mechanism, the longitudinal drive mechanism and the transverse drive mechanism are sequentially controlled to drive the horizontal pressing plate and the side pressing plate to carry out press fit on the lamp strip, the device is simple in structure, convenient to operate and high in alignment precision, the lamp strip press-fit intensityis balanced, and the product quality is ensured.

Description

technical field [0001] The invention relates to the technical field of backlight production, and in particular designs a light bar pressing device, in particular, a light bar and a backboard bonding and fixing device. Background technique [0002] At present, the backlight module includes the light bar, the double-sided tape of the light bar, and the back plate. When the existing light bar is combined with the back plate, the light bar needs to be pressed to the back plate. The manual pressing currently used is likely to cause floating and pollution. Or the problem of damage to the light bar; the pressing device used needs to press the light bar to the two sides of the back panel twice. Specifically, the back panel is fixed first, and the light bar is pressed on one side of the back panel through the device. On the side, after the pressing is completed, manually rotate the back panel, reposition, and then press the other side of the device through the device light bar. [0...

[0002] At present, the backlight module includes the light bar, the double-sided tape of the light bar, and the back plate. When the existing light bar is combined with the back plate, the light bar needs to be pressed to the back plate. The manual pressing currently used is likely to cause floating and pollution. Or the problem of damage to the light bar; the pressing device used needs to press the light bar to the two sides of the back panel twice. Specifically, the back panel is fixed first, and the light bar is pressed on one side of the back panel through the device. Side, after the pressing is completed, manually rotate the back panel, reposition, and then press the other side of the device through the device light bar

[0003] The above-mentioned light bar pressing device needs two positionings, there may be errors between the two positionings, and the problem of poor accuracy occurs. At the same time, two separate pressings will cause a gap between the light bar and the backplane bracket, which will affect the quality of the backlight module. Lead to the appearance of light leakage, resulting in the display quality of the display device
