Description
[technical field]
The utility model relates to a kind of welder, particularly relates to a kind of liquid crystal display and welds accurate alignment device.
[background technology]
Its glass plate of liquid crystal display industry is connected with soft band between the circuit board and all needs accurate contraposition, especially military LCDs.Common solder technology is very ripe.Because between the glass substrate on the liquid crystal display and the soft band connection of FPC is different media; Must can accomplish through a kind of special material transition; Should guarantee that the line row of gathering connects reliability and the production efficiency that guarantees connection again; Must before beginning hot pressing, guarantee densely covered line row's between glass substrate and the soft band of FPC accurate contraposition, reach hot pressing welding and promptly meet the demands.
At present; Traditional electric energy meter liquid crystal welding employing is backlight welds as benchmark; This traditional welding manner need be through the liquid crystal position of locating backlight; Because there is certain requirement the liquid crystal position, the drawback of conventional method welding method is that the left-right and front-back direction all can not be located, and the position was not placed in the middle after window was passed through in installation; The levelness of short transverse can not be controlled, and the welding back is inhomogeneous with direct gap backlight, causes the liquid crystal display display brightness also inhomogeneous, has a strong impact on product quality and production efficiency.
[summary of the invention]
The purpose of the utility model is in order to overcome the deficiency of prior art, provide a kind of simple in structure, accurate positioning, welding accurately, installation effectiveness and the high liquid crystal display of yield weld accurate alignment device.
In order to solve the problems of the technologies described above; The utility model has designed a kind of liquid crystal display and has welded accurate alignment device, it is characterized in that, comprises pcb board shop bolt, PCB location-plate, screw, support column, pedestal, pin, backlight, liquid crystal display and pcb board; Said liquid crystal display is fixed on the said pcb board through pin; Be provided with backlightly between said liquid crystal display and the pcb board, said pcb board is stuck on the said pedestal, and said PCB location-plate and said pedestal are fixed through screw; The back side of said pedestal is equipped with two support columns at least, is provided with the pcb board shop bolt around the said pcb board.
Said pcb board shop bolt is four.
The back side of said pedestal is equipped with four support columns, and each support column is installed in the edge of pedestal at interval.
The utility model beneficial effect compared with prior art is: because liquid crystal display is fixed on the pcb board through pin; Be provided with backlight between liquid crystal display and the pcb board; Pcb board is stuck on the said pedestal, and PCB location-plate and pedestal are fixed through screw, and the back side of pedestal is equipped with two support columns at least; Be provided with a plurality of pcb board shop bolts around the pcb board, the utlity model has simple in structure, accurate positioning, welding accurately, installation effectiveness and the high advantage of yield.
[description of drawings]
Fig. 1 is the decomposition texture sketch map of the utility model;
Fig. 2 is the assembly structure plane of the utility model;
Fig. 3 is the cutaway view of the utility model.
Referring to Fig. 1 to Fig. 3,1 is the PCB shop bolt; 2 is the PCB location-plate; 3 is screw; 4 is support column; 5 is pedestal; 6 are pin; 7 is backlight; 8 is liquid crystal display; 9 is pcb board.
[specific embodiment]
To combine accompanying drawing and specific embodiment to specify the utility model below, be used for explaining the utility model in the illustrative examples and the explanation of the utility model, but not as the qualification to the utility model.
Extremely shown in Figure 3 like Fig. 1; The liquid crystal display of the utility model welds accurate alignment device; Comprise pcb board shop bolt 1, PCB location-plate 2, screw 3, support column 4, pedestal 5, pin 6, backlight 7, liquid crystal display 8 and pcb board 9, said liquid crystal display 86 is fixed on the said pcb board 9 through pinning, and is provided with backlight 7 between said liquid crystal display 8 and the pcb board 9; Said pcb board 9 is stuck on the said pedestal 5; Said PCB location-plate 2 is fixing through screw 3 with said pedestal 5, and the back side of said pedestal 5 is equipped with two support columns 4 at least, is provided with a plurality of pcb board shop bolts 1 around the said pcb board 9.In the present embodiment, be provided with four pcb board shop bolts 1 around the said pcb board 9, the back side of said pedestal 5 is equipped with four support columns 4, and each support column 4 is installed in the edge of pedestal 5 at interval.
As shown in figures 1 and 3, will insert PCB location-plate 2 by PCB shop bolt 1, the back is connected pedestal 5 through pin 6, screw 3 to be fixed with PCB location-plate 2, at last with the support column 4 PCB location-plate 1 of packing into.So far, whole liquid crystal display welding tooling assembled, easy and simple to handle.With liquid crystal display 8 welding toolings, pedestal 5 is put into from top to bottom up and has been installed module, liquid crystal display 8, backlight 7 pcb board 8 of packing into, liquid crystal display up, then with feeler that can welded liquid crystal screen 8 after the frock upset.So far to reach the welding purpose, improve the precision and the efficient of welding.
The above in the spiritual category that does not break away from the utility model creation, is familiar with the protection domain that this technological various simple covert and modification that those skilled in the art did still belongs to the utility model only with the convenient the utility model of explaining.
