Description
Technical field
The utility model relates to LCD and detects utensil, is specifically related to a kind of backlight panel and lights tool.
Background technology
Backlight panel is liquid crystal display (LCD, Liquid Crystal Display) important component part, backlight panel produce process in, there will be various defect and bad point, such as cut, speckle with spot etc., affect the display effect of LCD.In order to improve the yield of final finished, needing to light backlight panel in making technology, detecting it and whether reaching required standard.This process need is used backlight panel and is lighted tool.
Traditional backlight panel lights tool as shown in Figure 1, and backlight panel is placed on tool, and the both positive and negative polarity contact copper sheet 13 of panel is lit.Because copper sheet area is large, along with the increase of service time, copper sheet is easily oxidized or dirty, causes loose contact, often can appearance point does not work in testing process phenomenon, affects testing process and work efficiency.
Utility model content
In order to overcome the above problems, the utility model discloses a kind of a kind of backlight panel of probes touch backlight panel that uses and lighting tool.
The technical solution of the utility model is as follows:
A kind of backlight panel lights tool, comprises bracing frame, probe structure and pin configuration; Support frame as described above comprises supporting back board and support plate; Described support plate and supporting back board become L shape to be connected;
Described probe structure comprises by compression leg, pressing plate, support column, probe, wire and spring; Described is a hollow cylinder by compression leg, is provided with annular first baffle plate inside the cylindrical wall of pressing capital end; Porose in described pressing plate, be describedly fixed in the hole of pressing plate by compression leg; Described support column is cylinder, support column has the annular second baffle that a circle protrudes; Described support column bottom is fixed in support plate; Described pressing column sleeve is outside described support column; Spring is placed with between described first baffle plate and second baffle; Described probe passes described pressing plate and is fixed in pressing plate, and the upper end of probe connects wire one end;
Described pin configuration comprises fixed mount and stem; Described fixed mount is arranged in described supporting back board; Described stem connects the wire other end; Described stem upper end is fixed on fixed mount.
Advantageous Effects of the present utility model is:
The utility model uses probe as the contact point lighting tool, contact backlight panel, and probe is more not oxidizable compared with copper sheet, can ensure to reduce error in test process, disposablely light backlight panel.And the utility model devises pressing structure, probes touch backlight panel can be controlled in operation flexibly or be separated backlight panel, reducing regulation time, improving the efficiency of test process.
The utility model structure is simple, easy to operate, and producing on line at LCD has very high practical value.
Accompanying drawing explanation
Fig. 1 is the backlight lightening tool schematic diagram of prior art.
Fig. 2 is the utility model schematic diagram.
Fig. 3 combines schematic diagram by compression leg and support column.
Fig. 4 is the sectional view that Fig. 3 cuts from A-A ' line.
Embodiment
Fig. 2 is the utility model schematic diagram, and backlight panel is lighted tool and comprised bracing frame, probe structure and pin configuration three parts.Bracing frame comprises supporting back board 1 and support plate 5, and support plate 5 is connected with supporting back board 1 one-tenth L shape, and backlight panel is placed in support plate 5 when testing.
Probe structure comprises by compression leg 2, pressing plate 3, support column 4, probe 6, wire 7 and spring 10.Pressing plate 3 has two holes, the described compression leg 2 pressed is for hollow cylinder, and the diameter in the hole in the overall diameter of hollow cylinder and pressing plate 3 matches, and two are separately fixed in two holes of pressing plate 3 by compression leg 2.Support column 4 is cylindrical, and two support column 4 bottoms are fixed in support plate 5, and two are enclosed within outside two support columns 4 respectively by compression leg 2.Probe 6 passes described pressing plate 3 and is fixed in pressing plate 3, and the upper surface of pressing plate 3 is exposed in the upper end of probe 6, connects one end of wire 7; The lower surface of pressing plate 3 is exposed in lower end, for contacting backlight panel.
Described pin configuration comprises fixed mount 8 and stem 9.Fixed mount 8 is L-type, and the vertical plane of L-type is arranged in supporting back board 1, and the plane of L-type is used for anchor leg post 9.Then whole pin configuration has been fixed on bracing frame.Stem 9 connects wire 7 other end, provides and lights backlight panel power supply used.
Fig. 3 is by the combination schematic diagram of compression leg 2 with support column 4, as can see from Figure 3, is enclosed within outside support column 4 by compression leg 2.
Fig. 4 is the sectional view that figure shown in Fig. 3 cuts from A-A ' line.As shown in Figure 4, be the top end of hollow cylindrical, hollow cylinder by compression leg 2, the inner side of cylindrical wall is provided with an annular baffle plate 11.Support column 4 is cylindrical, and support column 4 stage casing has a circle to protrude, and shape is the baffle plate 12 of annular.The diameter of bore of baffle plate 11 and the diameter of support column 4 of annular match, the race diameter of the baffle plate 12 of annular and matching by the internal diameter of compression leg 2.Spring 10 is placed with in the middle of baffle plate 11 and baffle plate 12.
When backlight panel lighted by needs, backlight panel is positioned over support plate 5 place, presses pressing plate 3, what be then fixed in pressing plate 3 is also downward by compression leg 2, and baffle plate 12 transfixion on support column 4, supports the bottom of spring 10, baffle plate 11 is downward with pressing plate, compresses the top of spring 10.The probe 8 be now fixed in pressing plate 3 also moves downward, and touches the both positive and negative polarity on backlight panel.Probe 6 upper end connects wire 7, and wire 7 needs long enough, can meet the distance that probe 6 moves downward, and when probe 6 is downward, wire 7 can be relatively stretching.Wire 7 is switched on power by stem 9, then backlight panel can be lit.
After detection terminates, decontrol pressing plate 3, spring 10 pops up, and supporting baffle 11 upwards, then drive whole pressing plate 3 to move upward, get back to original position.
Above-described is only preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate under the prerequisite not departing from spirit of the present utility model and design, all should think and be included within protection domain of the present utility model.
