As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0016] like Figure 1~2As shown, a self-tapping device for a display back panel includes a table panel 100, on which a plurality of support columns 110 for supporting the display back panel are provided, and a limit baffle 120 and a clamping mechanism 130 are provided around the display back panel on the table panel, and the limit baffle 120 is bent outward to facilitate the quick placement of the display back panel, and a plurality of guide sleeves 140 are provided below the display back panel on the table panel, and a tap 150 that can extend upward from the guide sleeve to drill holes in the display back panel is provided inside the guide sleeve, and a driving mechanism 200 for driving the tap to rise and rotate is provided below the table panel. The limit baffles 120 around the display back panel limit the front, back, left, and right positions of the display back panel, and the support columns 110 support the display back panel and are clamped and fixed by the clamping mechanism 130, and then the driving mechanism 200 drives the tap to rise and rotate to perform tapping at a specified position of the display back panel. The display back panel self-tapping device can tap multiple positions of the display back panel at one time, is easy to use, easy to operate, greatly saves processing time, and has high efficiency.

[0017] In this embodiment, a push rod 160 is provided in the guide sleeve and below the tap, which can rotate and slide relative to the guide sleeve. The tap is fixedly connected to the upper end of the push rod, and the lower end of the push rod passes downward through the table panel; the driving mechanism includes a lifting plate 210, and a first motor 220 corresponding to the push rod is provided on the lifting plate. The motor is connected to the push rod through a transmission rod 230, and the two ends of the transmission rod are respectively connected to the lower end of the push rod and the main shaft of the first motor through a universal joint 240. Each tap is driven to rotate by its corresponding first motor 200, and the lifting and lowering of the lifting plate is used to control all taps to rise and fall at the same time to control all taps to perform tapping and withdrawal actions; the use of a transmission rod and a universal joint for transmission connection can facilitate the layout and installation of the first motor, and the first motor does not need to be located directly below the push rod, and can be offset to a certain position, so that the transmission will not be stuck during the lifting process.

[0018] The tapping assembly consisting of the guide sleeve 140, the tap 150 and the push rod 160 is arranged according to the position of the threaded holes to be processed on the back panel of the display. The same number of tapping assemblies is arranged according to the number of threaded holes that need to be processed. At the same time, the same number of first motors are arranged on the lifting plate. When the number of first motors is large and difficult to arrange in a certain area, they can be installed at a certain offset.

[0019] In this embodiment, a plurality of vertical guide shafts 250 are provided under the table plate, and a guide hole is provided on the lifting plate for the vertical guide shafts to pass through and slide with the guide shafts; a second motor 260 is provided under the lifting plate, and a vertical screw rod 270 is coaxially connected to the main shaft of the second motor, and a nut seat 280 is provided in the middle of the lifting plate to threadably cooperate with the vertical screw rod. The lifting plate is driven by a threaded screw rod, and the lifting speed and height of the lifting plate, i.e., the tap, can be accurately controlled.

[0020] In this embodiment, in order to ensure more accurate positioning of the display back plate in the horizontal direction and improve the accuracy of the tapping position, a pair of positioning pins 170 for passing through the through holes on the display back plate are further provided on the table panel.

[0021] In this embodiment, the clamping mechanism 130 includes an L-shaped fixed plate 131, a swing arm 132 is hinged on the horizontal plate of the L-shaped fixed plate, a pressure plate 133 is fixedly connected to the swing arm, a pressure block is provided on the lower side of the end of the pressure plate, and a clamping cylinder 134 for driving the swing arm to swing is installed on the vertical plate of the L-shaped fixed plate, the telescopic rod of the clamping cylinder is hinged with the swing arm, and the swing arm is provided with a long hole for the hinge shaft to pass through to avoid the telescopic rod and the swing arm from getting stuck. The telescopic rod of the clamping cylinder 134 is extended, pushing the swing arm to swing toward the middle, so that the pressure block on the pressure plate presses the edge of the display back plate, and when the telescopic rod of the clamping cylinder 134 is contracted, the swing arm swings outward to release.
