Description

Technical Field

[0001] This utility model relates to the field of foot mounting device technology, and more specifically to a foot mounting device for LCD display processing. Background Technology

[0002] LCD display pin mounting refers to the installation of connection pins on the LCD screen. The installation of pins can improve the display effect of the LCD screen. In the production process, pin mounting is performed using a pin mounting device.

[0003] A search revealed an existing patent (publication number: CN214979017U) that discloses a pin-mounting device for LCD display processing. In its operation, a motor drives a turntable to rotate, causing a first triangular plate to press against a baffle, releasing the display screen onto the turntable. Then, a fixing plate presses against a second triangular plate, securing the display screen with a clamping plate. This ensures the pin-mounting device can fix the display screen securely during pin mounting, preventing positional deviations and maintaining display quality. However, the inventors discovered the following problems with the existing technology during the development of this invention: the aforementioned pin-mounting device only clamps and positions the display screen when using a pin-mounting tool for pin installation. After positioning, the screen's position is somewhat random and lacks precise position control. This makes it difficult to accurately install the pins in the designated positions on the display screen, resulting in poor installation quality and a low pass rate.

[0004] In view of this, the present invention proposes a foot mounting device for LCD display processing that facilitates the positioning and fixing of the display screen to solve this problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a mounting device for LCD display processing to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a foot mounting device for LCD display processing, including a processing table, a back plate fixedly mounted on the upper surface of the processing table, a hydraulic rod provided on the surface of the back plate, a foot mounter fixedly mounted on the telescopic end of the hydraulic rod, and a screen positioning component provided on the surface of the processing table corresponding to the foot mounter.

[0007] The screen positioning assembly includes a positioning tray set on the upper surface of the processing table. A positioning frame is set on the upper surface of the positioning tray. Two first positioning abutments are symmetrically arranged on the inner wall of the positioning frame. A second positioning abutment is set on the side of each of the two first positioning abutments away from the center line of the positioning frame. The two first positioning abutments and the second positioning abutments are combined to form a rectangular positioning cavity for the external display screen to be placed. The foot mount is positioned corresponding to the rectangular positioning cavity. An adsorption plate is set at the center of the upper surface of the positioning frame. The upper surface of the adsorption plate is slightly higher than the positioning tray. A negative pressure hole is opened on the surface of the adsorption plate. A negative pressure box is fixedly installed at the bottom of the processing table. An air pump is fixedly installed at the bottom of the negative pressure box. The air inlet of the air pump is connected to the inner cavity of the negative pressure box. A rubber hose is embedded in the front of the negative pressure box. The other end of the rubber hose passes through the positioning tray and is connected to the negative pressure hole on the surface of the adsorption plate.

[0008] As a further description of the above technical solution: A rectangular slide rod is fixedly installed on the surface of the first positioning plate. The rectangular slide rod is inserted into the surface of the positioning frame, and a first positioning screw is threadedly connected to the surface of the positioning frame. Several first positioning holes are opened on the surface of the rectangular slide rod, and the positions of the first positioning screw and the first positioning holes correspond to each other. A telescopic groove is opened at the end of the first positioning plate. A second positioning plate is inserted into the telescopic groove, and a second positioning screw is threadedly connected to the surface of the first positioning plate. Several second positioning holes are opened on the upper surface of the second positioning plate, and the positions of the second positioning screw and the second positioning holes correspond to each other. For different models of display screens, the rectangular slide rod is slidably connected to the positioning frame. Then, the first positioning screw is inserted into the first positioning holes at different positions to adjust and position the first positioning plate. Then, the second positioning plate slides inside the telescopic groove, and the second positioning screw is inserted into the second positioning holes at different positions for limiting. This can adjust the rectangular positioning cavity so that after the display screen is placed inside the rectangular positioning cavity, the position of the mounting feet corresponds to the position of the mounting feet, thus meeting the need for guiding and limiting display screens of different models and sizes.

[0009] As a further description of the above technical solution: the upper surface of the positioning tray is provided with a lifting groove, the adsorption plate is slidably connected inside the lifting groove, and an electric push rod is fixedly installed on the inner bottom wall of the lifting groove. The telescopic end of the electric push rod is fixed to the bottom side of the adsorption plate. By setting the electric push rod, after the pin installation action is completed, the adsorption plate is driven to move up by the extension of the electric push rod, which facilitates lifting the display above the rectangular positioning cavity, thereby facilitating the picking and unloading of the display.

[0010] As a further description of the above technical solution: the positioning frame is movably mounted on the surface of the positioning tray, and a slot is provided on the right side of the positioning frame. A locking block is fixedly installed on the right side of the upper surface of the positioning tray, and the locking block is locked inside the slot. A mounting bolt is threadedly connected to the left side of the upper surface of the positioning tray, and the threaded end of the mounting bolt abuts against the left side of the positioning frame. By movably mounting the positioning frame on the surface of the positioning tray, and using the mounting bolt and the locking block to position the positioning frame, the positioning frame can be removed from the surface of the positioning tray by rotating the mounting bolt, which facilitates the replacement of the positioning frame according to different sizes of display screens.

[0011] As a further description of the above technical solution: the positioning tray is movably mounted on the surface of the processing table, and a position adjustment component is provided between the processing table and the positioning tray.

[0012] As a further description of the above technical solution: the position adjustment component includes a transverse lead screw rotatably connected to the surface of the processing table. A first servo motor that drives the transverse lead screw to rotate is fixedly installed on the surface of the processing table. A connecting plate is threadedly connected to the surface of the transverse lead screw. A second servo motor is fixedly installed on the surface of the connecting plate. A longitudinal lead screw is fixedly installed on the output shaft surface of the second servo motor. A positioning plate is threadedly connected to the surface of the longitudinal lead screw. By setting the position adjustment component, the first servo motor drives the transverse lead screw to rotate, which can drive the connecting plate to move left and right. The second servo motor drives the longitudinal lead screw to rotate, which can drive the positioning plate to move back and forth. This allows for the adjustment of the position of the positioning frame, ultimately achieving the effect of adjusting the position of the positioning frame and the rectangular adjustment cavity, further satisfying the applicability of the lifting foot device.

[0013] As a further description of the above technical solution: a transverse limiting slide bar is fixedly installed on the surface of the processing table, and the connecting plate is slidably connected to the transverse limiting slide bar; by setting the transverse limiting slide bar, the stability of the connecting plate when moving laterally can be ensured.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1.

[0018] 3. Compared with the prior art, this LCD display processing foot mounting device, by setting an electric push rod, after the pin installation is completed, extends the electric push rod to drive the suction plate to move up, which facilitates the lifting of the display above the rectangular positioning cavity, thereby facilitating the picking and unloading of the display; the positioning frame is movably mounted on the surface of the positioning tray, and the positioning frame is positioned by mounting bolts and locking blocks. The positioning frame can be removed from the surface of the positioning tray by rotating the mounting bolts, which facilitates the replacement of the positioning frame according to different sizes of display screens, further enhancing the applicability of the overall device.

[0019] 4. Compared with the prior art, this LCD display processing foot mounting device, by setting a position adjustment component, uses a first servo motor to drive the horizontal lead screw to rotate, which can drive the connecting plate to move left and right, and uses a second servo motor to drive the vertical lead screw to rotate, which can drive the positioning tray to move back and forth, thereby adjusting the position of the positioning frame. Ultimately, it achieves the effect of adjusting the position of the positioning frame and the rectangular adjustment cavity, further satisfying the purpose of improving the applicability of the foot mounting device; by setting a horizontal limiting slide bar, the stability of the connecting plate during horizontal movement can be ensured; by setting a vertical limiting slide bar, the stability of the positioning tray during vertical movement can be ensured.
