Abstract
The utility model relates to a liquid crystal display module (LCM) test jig which comprises a base and a press plate arranged on the base. A sliding track is arranged on the base, a movable support is installed in the sliding track, the press plate is installed on the movable support, a press clip is arranged at one end of the press plate, and the press clip is used for controlling up-down press of the press plate. A transition plate is arranged under the press plate, and a test pin is arranged on the transition plate. The jig further comprises a power supply circuit and a test circuit which are sequentially connected and a voltage protection circuit connected with the power supply circuit. The test circuit is connected with a product to be tested through the test pin. The LCM test jig is strong in generality, simple in operation, capable of effectively improving test efficiency, safe and reliable due to the fact that circuit protection measures are arranged in the jig.
Description
Technical field
The utility model relates to a kind of measurement jig, is specifically related to a kind of measurement jig that is used to test the LCM module.
Background technology
In the prior art; The test of LCM module generally is man-to-man form with tool, develops a measurement jig separately to each module, and the groove of special with good grounds module size design is used to place module to be measured in the tool; And a clip is set is used to grasp module, the test of switching on again.There is following shortcoming in this measurement jig: (1) all needs washing trough again, location and replacing clip to each new model product, uses too limitation, causes the waste of material and man-hour; (2) use above-mentioned traditional testing tool, also cause the tester tired easily, influence work efficiency; (3) the tool WV is 5V, and voltage surpasses 5V mainboard easy burn-out, does not have protect measure.
The utility model content
In order to address the above problem, the utility model provides a kind of LCM measurement jig with versatility.
The technical scheme of the utility model is following: a kind of LCM measurement jig; Comprise base and be arranged at the pressing plate on the base that it is characterized in that, said base is provided with sliding rail; Travel(l)ing rest is installed in the sliding rail; Pressing plate is installed on the travel(l)ing rest, and pressing plate one end is provided with pressing clip, through pressing clip realize pressing plate up and down by pressure-controlled.
Said pressing plate below is provided with rebound, and rebound is provided with the test pin.
Said tool also comprises power circuit, the test circuit that connects successively, and test circuit is connected to product to be measured through the test pin.
Said tool also comprises the voltage protection circuit that is connected with power circuit.
Compared with prior art, the beneficial effect of the utility model is following: (1) said tool can be used for testing multiple LCM module, and highly versatile is simple to operate, can effectively improve testing efficiency; (2) said tool operating voltage range is wide, and is provided with protect measure, and is safe and reliable; (3) said tool volume is little, simple and easy lightly, cost is low.
Description of drawings
Fig. 1 is the utility model example structure synoptic diagram.
Embodiment
In order to let those skilled in the art can understand the technical scheme of the utility model better, the utility model is done further to set forth below in conjunction with accompanying drawing.
LCM measurement jig as shown in Figure 1, that the utility model disclosed comprises base 1, pressing plate 2, travel(l)ing rest 3, pressing clip 4.Wherein, travel(l)ing rest 3 is arranged on the base 1 through sliding rail, and pressing plate 2 is installed on the travel(l)ing rest 3; The pressing plate below is provided with rebound 5; Rebound is provided with test pin 6, and an end of pressing plate 2 is provided with pressing clip 4, through pressing clip 4 realize pressing plates up and down by pressure-controlled.
Said tool adopts the power supply of 5-12V power supply, and the electronic circuit of tool partly comprises power circuit, the test circuit that connects successively, and test circuit is connected to product to be measured through the test pin.Power unit also comprises the voltage protection circuit that is connected with power circuit.
During use; Product to be measured is positioned on the measurement jig; Put in order the position of travel(l)ing rest 3 according to the adjustable size of product to be measured; Be located at product to be measured top, the position is adjusted the back and is pushed pressing plate 2 through pressing clip 4, and the test pin on the product to be measured is closely contacted with test pin 6 on the rebound 5.Connect voltage then, test getting final product.
The above-mentioned more excellent embodiment of the utility model that is merely; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these changes and distortion all should belong to the protection domain of the appended claim of the utility model.
