When the assembly detection device 180 detects that the assembly between the protective frame 200 and the backlight module is not qualified, the assembled backlight module is stopped from being transported to the blanking station, and the assembled backlight module is selected and reassembled. On the contrary, when the assembly detection device 180 detects that the assembly between the protective frame 200 and the backlight module is qualified, the assembled backlight module is transmitted to the blanking station through the backlight module transmission mechanism 110, so that the assembled backlight module is taken down from the backlight module transmission mechanism 110.

From this, can in time discover to assemble unqualified backlight unit and guard frame 200 through setting up equipment detection device 180 to the equipment qualification rate between effectual improvement backlight unit of ability and the guard frame 200.

In some embodiments, the assembly detection device 180 is an Automatic Optical Inspection (AOI) detector, and when the AOI detector detects, a camera in the AOI detector scans the backlight module and the protection frame 200 automatically, collects assembly image information between the backlight module and the protection frame 200, and then compares the collected image information with preset image information, if the collected image information is within a range of the preset image information, it indicates that the assembly between the backlight module and the protection frame 200 is qualified, otherwise, when the collected image information is outside the range of the preset image information, it indicates that the assembly between the backlight module and the protection frame 200 is unqualified, and the assembly needs to be reassembled.

The assembled backlight module detected by the assembly detection device 180 is transmitted to the blanking station through the backlight module transmission mechanism 110, and the assembled backlight module at the blanking station needs to be taken down from the backlight module transmission mechanism 110. Based on this, in some embodiments, the assembling apparatus further includes a backlight module blanking mechanism 190, and the backlight module blanking mechanism 190 can remove the assembled backlight module from the backlight module conveying mechanism 110.

Therefore, the backlight module to be assembled is pressed by the pressing mechanism 106, so that the vacuum degree between the backlight module to be assembled and the jig 300 can be ensured, and the stability of the backlight module to be assembled on the jig 300 is further ensured.

In summary, before assembling the backlight module to be assembled with the protective frame 200 to be assembled, the automatic film tearing mechanism 101 firstly tears off the protective film on the backlight module to be assembled, so that the function detecting device 102 detects the function of the backlight module to be assembled (i.e. whether all the backlights in the backlight module to be assembled can be lit). After the function detection device 102 detects the functions of the backlight module to be assembled, the backlight module to be assembled is loaded to the backlight module transmission mechanism 110 by the backlight module loading mechanism 103, the backlight module transmission mechanism 110 firstly moves the backlight module to be assembled to the film attaching station to attach the protective film, meanwhile, the protective film to be attached is moved to the protective film attaching mechanism 104 by the protective film loading mechanism 105, and the protective film attaching mechanism 104 can attach the protective film to the backlight module to be assembled. After the protective film is attached, the limiting rod 320 on the jig body 310 is detached by the limiting rod detaching mechanism 140, so that one side edge of the assembled protective edge of the backlight module to be assembled extends out of the jig body 310, and then the backlight module to be assembled is flattened by the flattening mechanism 106, so as to ensure the vacuum degree between the backlight module to be assembled and the jig 300. Finally, the backlight module transmission mechanism 110 moves the backlight module to be assembled to the assembling station, and the assembling mechanism 130 assembles the protection frame 200 to be assembled and the backlight module to be assembled. After the protective frame 200 and the backlight module are assembled, the activating mechanism 160 is firstly used for extruding the protective frame 200 and the backlight module so as to bond the glue layer on the inner side surface of the protective frame 200 and the surface of the backlight module, then the disassembled limiting rod 320 is installed on the jig body 310 through the limiting rod loading mechanism 170, finally the assembling detection device 180 is used for detecting whether the assembling of the protective frame 200 and the backlight module is qualified, and if the assembling of the protective frame 200 and the backlight module is qualified, the assembled backlight module is taken down from the backlight module transmission mechanism 110 through the backlight module unloading mechanism 190.
