Description

Technical Field

[0001] The utility model relates to the technical field of shaping jigs, in particular to a shaping jig for a large antenna plate. Background Art

[0002] With the rapid development of communication technology, the frequency band used by signals is constantly expanding, while the vibrators with different structures on the antenna can generally only receive signals within a certain frequency range. Therefore, in order to cover wider frequency signals, most current antennas will be installed with a variety of vibrators with different structures, resulting in the antenna boards carrying these vibrators becoming larger and larger and the structure becoming more and more complex.

[0003] Most large antenna boards have complex structures and are generally formed using die-casting molds during production. However, the action of the die-casting mold using ejector pins to push the antenna board from multiple points to demold it during the demolding process often affects the flatness of the large antenna board. The larger the board size and the more complex the structure, the more obvious the flatness problem. During assembly, the vibrator can be roughly manually fine-tuned when assembling it. However, on some ultra-thin and complex antenna products, the upper and lower spacing of the external shell is relatively small. The deformation of the antenna board during assembly will directly affect the assembly of some vibrators and even affect their function. Manual fine-tuning is time-consuming and labor-intensive, and the fine-tuning effect cannot be guaranteed. Utility Model Content

The first feature being "under", "beneath" and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the horizontal height of the first feature is lower than that of the second feature.

[0024] For ease of understanding, Figure 1 The structural schematic diagrams of the upper and lower end faces of the large antenna board in this embodiment are shown from two perspectives. It can be seen that a number of support protrusions 1 or grooves 2 are irregularly formed at both the upper and lower ends, and these are respectively used to support or position the vibrators or the cables connecting them.

[0025] As Figure 2-3 shown, a shaping fixture for a large antenna board includes a shaping plate that can be correspondingly disposed on a pressing fixture and is in transmission connection with it. The shaping plate includes a lower support plate 10 and an upper pressing plate 20.

[0026] As Figure 4 shown, a plurality of annular first protrusions 11 arranged in a "hui" character shape are provided at the upper end of the lower support plate 10. The upper end of each first protrusion 11 can be matched and abutted against the lower end of the antenna plate. A plurality of first avoidance holes 12 are provided on the outer wall and / or inner wall and / or upper end of the plurality of first protrusions 11; a solid lower support block 13 is further provided inside the innermost first protrusion 11 on the lower support plate 10; more than one first ventilation hole 14 is provided at the upper end of each first protrusion 11 and the lower support block 13.

[0027] As Figure 5 shown, a plurality of annular second protrusions 21 arranged in a "hui" character shape are provided at the lower end of the upper pressing plate 20. The lower end of each second protrusion 21 can be matched and pressed against the upper end of the antenna plate. A plurality of second avoidance holes 22 are provided on the outer wall and / or inner wall and / or lower end of the plurality of second protrusions 21; a solid upper pressing block 23 is further provided inside the innermost second protrusion 21 on the upper pressing plate 20; more than one second ventilation hole 24 is provided at the lower end of each second protrusion 21 and the upper pressing block 23. A plurality of inner guiding members 25 are provided between the two second protrusions 22 on the upper pressing plate 20.

[0028] During operation, the lower support plate 10 and the upper pressing plate 20 are respectively fixed on the lower positioning seat and the upper positioning seat of the pressing fixture. Then, the antenna plate is placed on a plurality of first protrusions 11 and the lower support block 13, so that the support protrusions 1 at the lower end of the antenna plate fall between two adjacent first protrusions 11 or into the first avoidance holes 12; after the antenna plate is fixed in place, the fixture is started. The upper positioning seat of the fixture drives the upper pressing plate 20 to press down. During the pressing-down process, it is ensured that the inner guiding members 25 are not blocked by foreign objects. After complete pressing, the upper pressing plate 20 presses the lower end surface of the antenna plate completely against a plurality of first protrusions 11 and the lower support block 13. At the same time, a plurality of second protrusions 21 and the upper pressing block 23 are completely attached to the upper end surface of the antenna plate, achieving the purpose of leveling the antenna plate; after the pressing and leveling are completed, the fixture drives the upper pressing plate 20 to move upward. Since the second ventilation holes 24 have connected the cavities formed by surrounding a plurality of second protrusions 21 and the upper end of the antenna plate to the outside, the air pressure in the cavities is the same as that outside, and the upper pressing plate 20 can be separated from the antenna plate smoothly. Finally, the antenna plate is removed from the lower support plate. Similarly, since the first ventilation holes 14 have connected the cavities formed by surrounding a plurality of first protrusions 11 and the lower end of the antenna plate to the outside, the air pressure in the cavities is the same as that outside, and the antenna plate can be separated from the lower support plate 10 smoothly. The shape of the antenna plate will not be changed during the two separation operations, and the antenna plate always maintains the flatness when it is in the pressed state. It has been verified that the flatness of the antenna plate after pressing and leveling can reach within 0.3 mm, which can meet the assembly tolerance requirements of ultra-thin antenna products.

[0029] It can be understood that by setting a number of annular first protrusions 11 and second protrusions 12 arranged in a "hui" shape in sequence to press and flatten the lower end and the upper end of the antenna board, the contact area between the upper support board 10 and the lower pressing board 20 and the antenna board can be significantly increased, and the flattening effect can be improved; by setting a number of first avoidance hole grooves 12 and second avoidance hole grooves 22, the protrusion structures on the antenna board can be avoided to prevent damage to the antenna board, and by reasonably setting the shapes and depths of these avoidance hole grooves, they can be better matched with the protrusion structures on the antenna board, further increasing the contact area with the antenna board and improving the flattening effect; by setting a number of first ventilation hole grooves 14 and second ventilation hole grooves 24, a vacuum or negative pressure can be avoided from being formed in a number of cavities formed during pressing, ensuring that the jig can be smoothly opened and the flattened antenna board will not be deformed due to the air pressure difference, ensuring the flattening effect.

[0030] As Figure 2-3 shown, further, the shaping jig is also provided with more than one set of outer guiding components 30 and anti-fooling components 40. Each set of outer guiding components 30 is respectively arranged at the upper end of the lower support board 10 and the lower end of the upper pressing board 20, and includes a matching guide groove / guide sleeve or guide post. Each set of anti-fooling components 40 is respectively arranged on the side walls of the lower support board 10 and the upper pressing board 20.

[0031] It can be understood that the outer guiding member 30 can correct the pressing direction of the upper pressing board 20 to ensure that the second protrusion 21 will not damage the antenna board; the anti-fooling component 40 is convenient for visually checking the assembly direction when correctly assembling the lower support board 10 and the upper pressing board 20 onto the lower positioning seat and the upper positioning seat of the pressing jig, avoiding reverse installation and improving the assembly efficiency.

[0032] The above does not impose any limitation on the technical scope of the present invention. Any modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
