Detailed Description
The following detailed description of the embodiments of the present invention with reference to the drawings and specific examples is provided for further understanding the objects, aspects and effects of the present invention, but not for limiting the scope of the appended claims.
Referring to fig. 1 to 2, which are a perspective view and an exploded view of the present invention, the present invention includes: a base 10, a carrier 20, a jig plate 30 and a pressing jig 40, wherein:
the surface of the base 10 is provided with a plurality of positioning posts 11.
The carrier 20 is disposed across the surface of the base 10, and has a first window 21 therein, a plurality of positioning blocks 22 are disposed on the peripheral surface of the carrier 20, and the positioning posts 11 on the surface of the base 10 pass through the first window 21 of the carrier 20; in addition, a plurality of elastic columns 23 are respectively disposed on the periphery of the carrier 20, and the elastic columns 23 may be springs or rubber columns, so that the carrier 20 is disposed across the surface of the base 10.
The bottom of the jig plate 30 is provided with a plurality of positioning sleeves 31, and the positioning sleeves 31 are respectively sleeved on the positioning posts 11, so that the height of the bottom surface of the jig plate 30 (the so-called bottom surface, i.e. the surface of the jig plate 30 on which the positioning sleeves 31 are arranged) is at least higher than or equal to the height of the top surface of the carrier plate 20 (the so-called top surface, i.e. the surface of the carrier plate 20 on which the positioning blocks 22 are arranged); it should be noted that the positioning sleeves 31 are elastic, and can be rubber rings or springs, so that the bottom surface of the jig plate 30 does not directly contact the positioning posts 11 of the base 10, i.e. there is a gap between the bottom surface of the jig plate 30 and the positioning posts 11.
The pressing fixture 40 is disposed around the base 10, for example, a spanning mechanism such as a gantry structure, the pressing fixture 40 has a push rod 41, a press plate 42 is connected below the push rod 41, a second window 43 is disposed in the press plate 42, the second window 43 faces the first window 21 of the carrier 20, the second window 43 is slightly larger than the first window 21, and an inner edge of the second window 43 faces the positioning blocks 22 of the carrier 2; and, the push rod 41 is a motor, a pneumatic cylinder, a hydraulic cylinder or a manual method, and drives the pressing plate 42 to reciprocate and generate a pre-applied pressure.
When a predetermined lcd 50 is to be tested, please refer to fig. 3, which is a schematic operation diagram (i) of the present invention, first, the lcd 50 is placed on the surface of the carrier 20, and the periphery of the lcd 50 is defined between the positioning blocks 22, and meanwhile, the jig plate 30 is the first window 21 penetrating through the carrier 20, so that the bottom of the lcd 50 covers the top surface of the jig plate 30 (the other surface is the top surface, opposite to the bottom surface of the jig plate 30); next, please refer to fig. 4, which is a schematic operation diagram (two) of the present invention, wherein the pushing rod 41 of the pressing fixture 40 moves to drive the pressing plate 42 to move downward, and it should be noted that, the pushing rod 41 drives the pressing plate 42 to move toward the surface of the base 10 by taking the surface of the base 10 on which the positioning pillars 11 are disposed as a reference point, so that the pressing plate 42 moves downward relative to the surface of the base 1; when the pressing plate 42 continuously moves and covers the surface of the carrier 20 (as well as the surface of the carrier 20 defined above), since the second window 43 of the pressing plate 42 is slightly larger than the first window 21 of the carrier 20 and the inner edge of the second window 43 faces the positioning blocks 22 on the surface of the carrier 20, the top surface of the lcd screen 50 is attached to the bottom surface of the pressing plate 42, the bottom surface of the lcd screen 50 is attached to the surface of the carrier 20, and the side surfaces (i.e. the side surfaces, which refer to the surfaces of the lcd screen 50 perpendicular to the bottom surface and the bottom surface, respectively) of the lcd screen 50 are between the positioning blocks 22 of the carrier 20.
Please refer to fig. 5, which is a schematic diagram (iii) of the operation of the present invention, because the plurality of elastic columns 23 are respectively disposed on the periphery of the carrier 20, the push rod 41 of the pressing tool 40 can drive the pressing plate 42 to push the carrier 20 downward, so that the bottom surface of the carrier 20 is attached to the surface of the base 10, or the distance between the bottom surface of the carrier 20 and the surface of the base 10 is reduced, at this time, the periphery of the lcd 50 (bearing the above-mentioned force of pressing the pressing plate 42) and the bottom surface of the lcd 50 are subjected to the resistance of the tool plate 30, so that the lcd 50 is bent, it should be noted that the bending of the lcd 50 in the present invention means the deformation of the lcd 50 when being forced, but the bending amplitude and the pressing force of the pressing plate 42 are still within the safety value of the lcd 50, i.e. the lcd 50 is based on the characteristics of the material, for example, if the lcd panel 50 is bent with a safety force of 1 kg, the pushing rod 41 of the pressing fixture 40 drives the pressing plate 42 to generate a downward force of less than 1 kg, so as to ensure that the lcd panel 50 will not be broken due to an excessively large bending range.
Furthermore, as mentioned above, there is a gap between the bottom surface of the jig plate 30 and the positioning posts 11, so that the positioning sleeves 31 on the bottom surface of the jig plate 30 can buffer the pressure of the lcd panel 50 on the pressing plate 42, and disperse the pressure, thereby further preventing the lcd panel 50 from breaking. When the push rod 41 of the press fixture 40 drives the press plate 42 to move upward (compared with the above-mentioned downward movement, i.e. the movement in the opposite direction), when the press plate 42 is separated from the carrier 20, the elastic columns 23 on the periphery of the carrier 20 release the pressure, so that the bottom surface of the carrier 20 is changed from the state of being attached to the surface of the substrate 10 to the separated state, or the distance between the bottom surface of the carrier 20 and the surface of the substrate 10 is restored to the untested state (the so-called untested state, i.e. the state where the bottom surface of the press plate 42 is not attached to or pressed against the carrier 20), and meanwhile, the positioning sleeves 31 on the bottom of the fixture plate 30 are provided with elasticity, so that the lcd screen 50 can be quickly restored to the untested state.
Please refer to fig. 6, which is an exploded perspective view of a base according to another embodiment, compared to fig. 1 to 5, the difference is that a plurality of fixing holes 12 are formed on a surface of the base 10, and fixing blocks 111 are respectively formed at bottoms of the positioning pillars 11, so that the positioning pillars 11 can be replaced at different positions according to actual requirements, and the bending position, the bending amplitude, and the like of the lcd 50 can be changed according to actual requirements according to different positions.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
