Abstract
The utility model discloses a lighting short circuit measuring tool which comprises a body, wherein a positioning groove which is used for fixing a back light source product is arranged on the body, a power source which can be electrically connected with a circuit board of the back light source product is also arranged on the body, one side of the positioning groove is provided with a spring piece and a lamp, and the spring piece, the lamp and a cathode of the power source are electrically connected sequentially. After the back light source product is fixed in a fixing groove, a lampshade is in contact with the spring piece. When the lampshade of the back light source product and a tin disk are in a short circuit, current can flow to an LED lamp from the spring piece and lead the LED lamp to light, an operator can judge whether a short circuit exists by observing whether the LED lamp lights, then, the next step is carried out, thus, when the back light source product is in a short circuit, a film structure has no need to be examined, consequently, the unnecessary operation can be reduced to improve work efficiency, and meanwhile, the product qualification rate of the next working procedure can be increased.
Description
Technical field
The utility model relates to a kind of tool, refer to especially a kind of be used to detect on the backlight product whether have a stain, cut or impurity, and detect it simultaneously and whether have lighting a lamp of short circuit to survey the short circuit tool.
Background technology
Backlight product is the parts that are applied on the display screen, and it is that film by multi-layer transparent is formed by stacking, and the one side is equipped with by the fixing light tube group 12 of lampshade 11, and as shown in Figure 1, a side of light tube group 12 is connected with a flexible PCB 14 by tin dish 13.Because the membrane structure of backlight product may be sneaked into impurity in manufacture process, may have a stain in addition, cut etc., this all can influence the quality of display screen.Therefore, the backlight product after the making has important operation one, checks exactly whether product is qualified, for example whether has a stain on its membrane structure, cut or impurity etc., and this procedure is finished by the tool of lighting a lamp.
Traditional tool of lighting a lamp comprises a body, has a locating slot that is used to place backlight product on the body, also is circumscribed with power supply on the tool.When detecting, the workman is placed on backlight product in the locating slot, and make its flexible PCB 14 be electrically connected with power supply on the tool, turn on the power switch then and make light tube group 12 electrified light emittings, light is by the irradiation of membrane structure one side of backlight product, so flaws such as the workman can clearly find out on the transparent membrane structure whether have a stain, cut or impurity.
Yet, backlight product may defectiveness on membrane structure, its tin dish 13 also is short-circuited easily with lampshade 11, this is because the cause (cooperating shown in Figure 1) that the tin dish 13 and the position of lampshade 11 are leaned on nearerly.But whether the lampshade of backlight product and tin dish are short-circuited, only on attaching it to display screen after, light tube group 12 does not work and just can be found, this has influenced the efficient that display screen is produced greatly.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of and is used to check whether the short circuit tool is surveyed in qualified lighting a lamp to backlight product, and it can detect the whether short circuit of its lampshade and tin dish earlier before checking that the backlight product membrane structure is whether qualified.
For solving the problems of the technologies described above, technical solution of the present utility model is:
A kind of lighting a lamp surveyed the short circuit tool, comprises a body, and body is provided with the locating slot that is used for fixing backlight product, also is provided with the power supply that can be electrically connected with the circuit board of backlight product; One side of this locating slot is provided with a spring leaf and lamp, and this spring leaf, lamp and power cathode are electrically connected successively; Its lampshade contacted with spring leaf after backlight product was fixed in pickup groove.
Also be provided with the fast ram pressure that is used for fixing backlight product on the described tool body.
After adopting such scheme, because the utility model is provided with whether short circuit current of a tin dish of being made up of spring leaf and LED lamp that can detect backlight product and lampshade on original tool of lighting a lamp, after as operating personnel backlight product being fixed on the locating slot of tool, can whether light by observing the LED lamp earlier, judged whether short circuit, and then carry out next procedure, like this, when backlight product short circuit, again its membrane structure is checked with regard to not needing, thereby can reduce unnecessary operation, increase work efficiency, can also increase the product percent of pass of subsequent processing simultaneously.
Description of drawings
Fig. 1 is the lampshade of backlight product and the synoptic diagram that the tin dish is short-circuited easily;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is a spring leaf wiring diagram of the present utility model;
To be the utility model place synoptic diagram in the locating slot with backlight product to Fig. 4;
Current direction synoptic diagram when Fig. 5 is not short circuit of backlight product;
Current direction synoptic diagram when Fig. 6 is the backlight product short circuit.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Shown in Fig. 2,3, the tool of lighting a lamp described in the utility model comprises a body 2, body 2 is provided with the locating slot 21 that is used for fixing backlight product, one side of locating slot 21 is provided with a spring leaf 3 and a lamp, this lamp can be red LED lamp 4, also be provided with power supply 5 on this body 2, wherein spring leaf 3, LED lamp 4 and power supply 5 negative poles are electrically connected successively.In addition, other part is installed also on the body 2, as is used for fixing the fast ram pressure 6 of backlight product, these assemblies are all identical with the structure and the function of traditional tool, do not give unnecessary details.
When detecting, as shown in Figure 4, backlight product 1 is fixed in the locating slot 21 of tool body 2, make its upper lamp shade 11 contact with spring leaf 3, be electrically connected with power supply 5 with seasonal its flexible PCB 14.Power-on then, when the tin dish 13 of backlight product 1 during with lampshade 11 not short circuits, electric current only flows to light tube group 12, make light tube group 12 luminous, as shown in Figure 5, and red LED lamp 4 does not light, and can continue to check on the membrane structure of backlight product 1 whether have a stain this moment, cut or impurity etc.If when tin dish of backlight product 1 13 and lampshade 11 short circuits, as shown in Figure 6, current direction light tube group 12, make light tube group 12 luminous, electric current also flows to red LED lamp 4 by lampshade 11 by spring leaf 3 simultaneously, makes red LED lamp 4 light, at this moment, operating personnel can light the lampshade 11 and tin dish 13 short circuit of judging backlight product 1 by LED lamp 4, thereby need not reexamine membrane structure whether flaw are not arranged, and can be judged as defective products.This kind detects the mode of short circuit in advance, not only can increase the qualification rate of postorder operation, can not need simultaneously because of the underproof product of short circuit carries out the inspection of membrane structure again, thereby can increase efficient.
