Description

Technical Field

[0001] The present invention relates to the technical field of display flat panel processing equipment, and more specifically to a continuous precision drilling processing device for a display shell. Background Art

[0002] The existing display or tablet housing needs to have a hole punched on the wall plate on one side of the upper frame to ensure that the camera component of the screen can shine through the hole to the outside world, so as to realize functions such as video chatting and taking pictures;

[0003] The existing shell frame has a wall plate on one side of the punching hole, which is generally punched by a punching device. When punching, the wall plate around the hole is easily deformed, affecting its quality. Therefore, it is necessary to install a horizontal support plate on the bottom surface of the frame. The current method is to manually install the horizontal support plate. At the same time, the horizontal support plate needs to be clamped and fixed, which can only be done by setting a pressure block on the horizontal support plate. The pressure block needs to be fixed on the stand fixed by the shell, and generally needs to be fixed with bolts, etc., which is troublesome to fix. Moreover, each time a piece is completed, it needs to be disassembled and reassembled, which is very troublesome, the manual labor is large, and the efficiency is low.

[0004] Meanwhile, the existing shell is generally fixed by using a cylinder push rod to push the pressure plate to press and fix it. However, since the wall plate of the shell is very thin, pressing it with the pressure plate can easily cause its surface to deform. That is, when the pressure plate is pressed, indentations are easily generated at the pressing position, affecting its appearance. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a continuous and precise drilling processing device for a display shell, which can adsorb and fix the display shell without the need for a pressure plate to press it, so that its surface is not easily deformed or indented, thereby ensuring the surface appearance. It can automatically move the support block so that its top surface provides bottom support for the upper bent edge on the left side, thereby ensuring the drilling effect.
