[0018] Example

[0019] To address the aforementioned technical problems, this embodiment provides a front frame pressing fixture, such as... Figure 1 As shown, the device includes a base 10 and a pressing assembly 20 suspended at the top of the base 10. A receiving groove 11 for accommodating the front frame is provided within the base 10. Clamping assemblies 12 are provided on both sides of the receiving groove 11 on the base 10. A suction assembly 13 is also provided within the receiving groove 11. By providing the receiving groove 11 on the base 10 and the suction assembly 13 within the receiving groove 11, the front frame of the display screen can be fixedly positioned within the receiving groove 11. Furthermore, by providing the clamping assemblies 12 on both sides of the receiving groove 11, it is ensured that the front frame of the display screen and the glass can be precisely bonded during the pressure-holding process. Finally, by suspending the pressing assembly 20 at the top of the base 10, the pressure-holding process between the front frame of the display screen and the glass is completed, ensuring that the glass adheres to the display front frame during the pressure-holding process and improving the product's yield rate.

[0020] Specifically, such as Figure 2 As shown, the suction assembly 13 includes several sets of suction pipes 131 that are opened in the receiving groove 11 and extend to the side wall of the base 10. A suction device is connected to the suction pipe 131 on the side of the base 10. By providing a suction pipe 131 extending to the side wall of the base 10 in the receiving groove 11, and by connecting a suction device to the suction pipe 131, the front frame of the display screen can be suctioned and adsorbed into the receiving groove 11 by the suction device, thereby completing the positioning and fixing of the front frame of the display screen.

[0021] In the above scheme, the pressing assembly 20 comprises support frames 21 arranged on both sides of the base 10, a first driving assembly 22 is arranged on the support frame 21, a lower pressing block 23 is connected to the driving end of the first driving assembly 22, and a pressing plate 24 is further connected to the side of the lower pressing block 23 facing the accommodating groove 11. The first driving assembly 22 can be a driving motor. The lower pressing block 23 is connected to the driving end of the first driving assembly 22, and the pressing plate 24 is connected to the lower pressing block 23. During the pressure maintaining process, the first driving assembly 22 drives the lower pressing block 23 to move along the side facing the accommodating groove 11, and the pressing plate 24 connected to the lower pressing block 23 can maintain the pressure of the display front frame and the glass placed in the accommodating groove 11 during the pressure maintaining process.

[0022] Further, the pressing assembly 20 further comprises a guide groove 25 opened in the inner side wall of the support frame 21, a guide column 26 is arranged in the guide groove 25, a guide block 27 is slidably arranged on the guide column 26, and the guide block 27 is fixedly connected to the lower pressing block 23. The guide column 26 is arranged in the guide groove 25, and the guide block 27 connected to the lower pressing block 23 is slidably arranged on the guide column 26. When the first driving assembly 22 drives the lower pressing block 23 to move, the guide block 27 slidably arranged on the guide column 26 can move in a guided manner, thereby guiding the movement of the lower pressing block 23 to drive the pressing plate 24 to maintain the pressure.

[0023] In order to accurately adjust the pressing stroke of the pressing plate 24, as a preferred embodiment, a pressure sensor is further arranged in the lower pressing block 23. When the lower pressing block 23 drives the pressing plate 24 to maintain the pressure of the display front frame and the glass during the pressure maintaining process, the pressure sensor can detect the pressure value provided by the pressing plate 24, and then the pressing stroke of the pressing plate 24 can be adjusted according to the pressure value required by the display front frame and the glass during the pressure maintaining process.

[0024] Specifically, the clamping assembly 12 comprises a clamping plate 121 slidably arranged in the accommodating groove 11, a top rod 122 abutting against the clamping plate 121 is threadedly connected to the side of the base 10, an elastic member 123 is sleeved on the outer periphery of the top rod 122, and the two ends of the elastic member 123 abut against the inner side wall of the clamping plate 121 and the accommodating groove 11, respectively. The clamping plate 121 is arranged in the accommodating groove 11, and the top rod 122 is arranged in the clamping plate 121 by being threadedly connected to the side of the base 10. The end of the top rod 122 arranged on one side of the clamping plate 121 is provided with an abutting block. In this embodiment, the abutting block can be a square abutting block. Further, the elastic member 123 is arranged on the outer periphery of the top rod 122, so that the clamping plate 121 can be driven to slide by rotating the top rod 122, thereby clamping the display front frame and the glass placed in the accommodating groove 11, and ensuring the fitting precision of the display front frame and the glass.

[0025] In the above scheme, the stop assembly 14 is arranged on both sides of the base 10 located on the clamping assembly 12, the stop assembly 14 includes a rotating shaft 141 arranged on the side wall of the base 10, and a stop block 142 is arranged on the side of the rotating shaft 141 extending towards the pressing assembly 20. In order to accurately adjust the pressing stroke of the pressing plate 24, as another embodiment, a rotating shaft 141 can also be arranged on the side wall of the base 10, and a stop block 142 is arranged on the rotating shaft 141. When the pressing assembly 20 performs the pressure maintaining process on the front frame of the display and the glass, the rotating shaft 141 can be adjusted to drive the stop block 142 to be arranged parallel to one side of the pressing plate 24, and then when the pressing plate 24 presses the glass on the front frame of the display, the stop block 142 first abuts against the glass to perform the pressure maintaining process, and then contacts the stop block 142 arranged after advancing a certain stroke, thereby completing the adjustment of the pressing stroke of the pressing plate 24, and realizing the setting of the pressing stroke of the pressing plate to control the pressure maintaining pressure of the pressing plate.

[0026] In summary, in one or more embodiments of the present application, the present application provides a front frame pressing jig, which includes a base and a pressing assembly suspended on the top end of the base. An accommodating groove for accommodating the front frame is formed in the base, and a clamping assembly is arranged on both sides of the base located in the accommodating groove. An suction assembly is also arranged in the accommodating groove. By forming the accommodating groove in the base and arranging the suction assembly in the accommodating groove, the front frame of the display screen can be fixedly arranged in the accommodating groove. By arranging the clamping assembly on both sides of the accommodating groove, the front frame of the display screen can be accurately attached to the glass during the pressure maintaining process. By suspending the pressing assembly on the top end of the base, the pressure maintaining process of the front frame of the display screen and the glass is completed by the pressing assembly, which ensures that the glass is attached to the front frame of the display during the pressure maintaining process and improves the qualified rate of product production.
