  "abstract": "The present discourse relates to a technical field of a manufacture of a display device, and in particular relates to a light bar assembling device and a light bar assembling method using the light bar assembling device. The light bar assembling device includes a rotating platform and a press drive module disposed at an outside of the rotating platform. The rotating platform is provided with bonding process positioning carriers for back plates to be bonded with the light bar and pressing process positioning carriers for the back plates bonded with the light bars. The press drive module is configured to perform a pressing operation on the light bar bonded at the back plate. The device can integrate the bonding process and the pressing process, improving work efficiency.",
  "claims": [
    "1. A light bar assembling device, comprising: a rotating platform provided with bonding process positioning carriers for a back plate to be bonded with the light bar and pressing process positioning carriers for the back plate bonded with the light bar, wherein each of the bonding process positioning carriers has a groove that matches a side edge of the light bar to be mounted, and each of the pressing process positioning carriers has a boss that matches a body shape of the back plate bonded with the light bar; and a press drive module disposed at an outside of the rotating platform and comprising a pressing head, wherein the press drive module is configured to drive the pressing head to stretch out in a plane parallel to a rotation plane of the rotating platform to perform a pressing operation on the light bar bonded at the back plate, when the pressing process positioning carrier carrying the back plate bonded with the light bar rotates along with the rotating platform to be aligned with the press drive module.",
    "2. The light bar assembling device according to claim 1, wherein the device is provided with two bonding process positioning carriers and two pressing process positioning carriers.",
    "3. The light bar assembling device according to claim 2, wherein the rotating platform is provided with a disc-shaped rotating base, and the bonding process positioning carriers and the pressing process positioning carriers are arranged at a surface of the base along a circumferential direction.",

  "description_excerpt": "The present discourse relates to a technical field of manufacture of a display device, and in particular relates to a light bar assembling device and a light bar assembling method using the light bar assembling device.\n\nIn a industrial chain of a TEL-LCD, a backlight product technology is an important part in this field, while an LED light bar is one of core components of a back light module. With the development of technology and the wide usage of the Liquid crystal display, higher requests have been put forward to the performance of Liquid crystal display in the market. For example, the liquid crystal display used in automobiles should be robust and shock resistant; some dashboard displays are required to be heat resistant; the strength of the liquid crystal displays need to increase while the thickness of the liquid crystal displays need to decrease. In traditional back light module, the LED light bar is fixed by screws. However, this fixing method is obsolete. Double side adhesive tape is currently used for bonding. However, during the operation of bonding using adhesive tape, the problems that the bonding is not tight enough, the strength of the bonding is not uniform enough and the bonding position is offset can easily occur. Therefore, during the assembling operation of the LED light bar, the components to be assembled must be effectively secured and positioned. After bonding, the light bar needs to be pressed and attached perpendicular to the surface of the light bar so that the light bar can be secured onto the back plate of the back light module accurately and tightly.",
