The full laminating technique is mature day by day, and because the cover plate is simple in structure with the display screen, the full laminating technique is only applied to the laminating of the cover plate and the touch screen at the initial groping stage. Due to the fact that the full-lamination technology is simple to operate, a large number of people consider applying the full-lamination technology to lamination of the touch screen and the display screen. The bottleneck that the touch screen is attached to the display screen most is that a gap exists between the display screen iron frame and the polaroid, and the gap problem is solved by the existing method, so how to test the sealing effect between the display screen iron frame and the polaroid is very important.
The traditional air tightness device mainly comprises a vacuumizing jig, an air tightness display device and a vacuum pump; the tightness between the display screen iron frame and the polaroid can be detected only when the detection environment is in a vacuum state; however, one product corresponds to one vacuumizing jig, the manufacturing cost of the jig is high, the production period of the vacuumizing jig is long, and the production progress of the product is influenced; meanwhile, a pressing device is not arranged above the display screen, and the external environment cannot reach a full-sealing state during the integral test.
Therefore, it is necessary to design a device for inspecting the sealability of a liquid crystal display panel to solve the above problems.
Disclosure of Invention
For overcoming the not enough among the above-mentioned prior art, the utility model aims to provide a liquid crystal display leakproofness inspection device.
In order to achieve the above objects and other related objects, the present invention provides a technical solution: the device comprises a device body and a hole plugging mechanism, wherein the device body comprises a vacuum platform for placing a liquid crystal display product, a plurality of vacuumizing row holes are uniformly formed in the surface of the vacuum platform, and the size of the hole plugging mechanism is smaller than that of the vacuum platform; when the holes are plugged, the hole plugging mechanism covers the partial vacuumizing row holes; one side of the vacuum platform is provided with a vacuum-pumping joint, and the vacuum joint is connected with an external vacuum pump; and a pressing platform is arranged above the vacuum platform.
Preferably, the vacuum platform and the pressing platform are both large-sized platforms.
Preferably, a sealing ring made of a softer material and matched with the liquid crystal display screen product is arranged on the liquid crystal display screen product.
Preferably, the pressing platform is connected with the air cylinder.
For the structural features of the above solution, the corresponding explanations are as follows:
when the device designed by the scheme is used for detecting the sealing performance of the liquid crystal display screen, the liquid crystal display screen product is firstly placed on the vacuum platform, and if the liquid crystal display screen does not cover all the vacuumizing row holes on the vacuum platform, the hole blocking device is used for blocking the residual uncovered vacuumizing row holes; then the pressing platform is pressed down to enable the vacuum platform, the liquid crystal display screen product and the pressing platform to be completely attached, and then the detection environment is in a complete vacuum state through the vacuumizing holes on the vacuum platform, so that additional vacuumizing equipment does not need to be added; the operation is convenient, the complete sealing of the test environment can be met, the equipment cost is effectively reduced, and the production period is shortened.
Set up vacuum platform and push down the platform and all be jumbo size platform, but the not unidimensional display screen of different models snap-on accomplishes the gas tightness test on jumbo size platform, compares in the evacuation tool of traditional one-to-one, reduces tool and sets up production cycle and manufacturing cost.
Be provided with the softer sealing washer of assorted material on liquid crystal display product, adopt wear-resisting, withstand voltage, the softer sealing washer of material, guaranteed the full leakproofness between display screen and the sealing washer in the test process, can protect the product not damaged when the platform that flattens down effectively simultaneously.
The push-down platform is driven by the air cylinder to be stable.
The utility model has the advantages that: the vacuum platform is arranged for vacuumizing, and no additional vacuumizing jig is needed, so that the production cost is reduced; a pressing platform is arranged above the vacuum platform, and the sealing ring can be ensured to be in complete contact with the display screen after the platform is pressed down, so that the vacuumizing value is reduced, and the complete sealing of a test environment is met; the sealing ring is made of a soft material, has high viscosity, is wear-resistant and high-pressure-resistant, can ensure that the display screen is in complete contact with the sealing ring, and reduces the production period of products; convenient to use, simple structure, the practicality is high.
