Description

Technical Field

[0001] The utility model relates to the technical field of television production, in particular to a television shell polishing device. Background Art

[0002] Since the birth of television, the functions and technologies of television have undergone major changes in recent years. The current televisions are becoming clearer and smarter, and will become the entrance to smart homes similar to mobile phones and smart speakers. They are not only the home audio-visual entertainment center, but also the information sharing center, control management center and multi-device interaction center. For televisions, the shell is one of the important components, which can not only reliably protect the internal components of the television, but also play a certain role in aesthetics. The TV shell produced by injection molding process often needs to be polished on the outside to obtain an external shape that meets the use requirements.

[0003] The TV casing produced by the prior art is mostly simply polished at its four edges by a polishing device, and it is impossible to perform polishing operations on other areas on the back of the TV casing, and it is impossible to produce a beautiful external structure. In addition, since the casing is not fixed firmly enough during processing, the polishing device will cause the TV casing to shift, making it impossible to perform the polishing operation stably. For this reason, we propose a TV casing polishing device. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a TV shell grinding device, which has a reliable shell mounting unit. The main suction cup and the auxiliary suction cup cooperate with each other to achieve a good fixing effect on the TV shell, thereby ensuring the stable progress of subsequent grinding processing. The utility model also has a reliable grinding control unit, which can control the grinding wheel to flexibly adjust the angle and position, and cooperate with the lateral movement of the sliding frame to perform multi-dimensional and multi-region grinding processing on the TV shell, thereby forming structures such as chamfers and rounded corners that can increase the beauty of the shell, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a TV housing polishing device, comprising a base, a housing mounting unit and a polishing control unit;

[0006] Base: The upper end of the right front side is fixedly connected with a mounting platform, and the PLC controller is installed on the oblique front side of the mounting platform;

[0007] Shell mounting unit: comprising an electric turntable, a mounting sleeve column, a main suction cup, a hydraulic cylinder 2, an auxiliary suction cup and a pressure sensor. The electric turntable is arranged above the mounting platform, and a supporting device is arranged on its lower side. A vertical mounting sleeve column is fixedly connected at the center position of the upper end of the electric turntable. The main suction cup is tightly mounted on the upper end of the mounting sleeve column. Eight hydraulic cylinders 2 are embedded in a circular array near the edge position of the upper end of the electric turntable.

[0009] The mounting sleeve is used for the installation of the main suction cup and plays a supporting role for the placed TV casing. The main suction cup is adsorbed on the middle part of the TV casing to play a major suction effect. After the main suction cup is adsorbed, the telescopic ends of the surrounding hydraulic cylinders rise upward to push the auxiliary suction cups to be adsorbed on the edge of the shell. When the PLC controller detects the pressure input through the pressure sensor, the hydraulic cylinders stop working. The main suction cup and the auxiliary suction cup cooperate with each other to achieve a good fixing effect on the TV casing, ensuring the stability of subsequent grinding processing. The grinding control unit is used to perform grinding operations on the TV casing. The electric turntable can drive the mounting sleeve and the TV casing placed above to rotate, thereby adjusting the horizontal angle of the shell to achieve grinding operations at multiple angles.

[0010] Furthermore, the housing mounting unit further comprises an air pump and an air nozzle. The air nozzle is embedded and installed at the center of the upper end of the mounting sleeve. An air pump is installed outside the circumference of the electric turntable. The air inlet end of the air pump is connected to the air nozzle through an internal pipeline.

The mounting frame is used to support the mounting plate. The electric turntable is mounted on the upper end of the hydraulic cylinder one through a ring fixedly connected at the center position of the lower end. The hydraulic cylinder one can push the electric turntable and the TV casing placed above to rise and fall, thereby realizing in-depth grinding in the vertical direction.

The front end and the oblique lower side of the installation box are both equipped with left and right visual lenses. The visual lens and the servo motor inside the side connecting frame are both bidirectionally electrically connected to the microprocessor inside the installation box. A longitudinal hydraulic cylinder 4 is installed inside the slide slot opened on the rear side of the upper end of the base. The telescopic end of the hydraulic cylinder 4 is fixedly connected to the lower front side of the sliding frame 2. The hydraulic cylinder 4 pushes the sliding frame 2 to move forward and backward, thereby adjusting the longitudinal position of the grinding wheel.
