Description

Technical Field

[0002] Liquid crystal display is a type of flat panel display. It is used for screen display of television and computer. In order to prevent the LCD screen from moving during processing, it needs to be fixed inside a fixing device.

[0003] After searching, the Chinese patent publication number CN118818825A discloses a fixing device for processing liquid crystal display screens. Although the device can facilitate the precise fixing of liquid crystal display screens of different sizes in the middle, in the process of fixing the liquid crystal display screen, the clamping and fixing mechanism needs to be driven by a motor to fix the liquid crystal on the surface of the device, which makes the device more dependent on the external power supply. When the power fails or is disconnected, the device will become unusable, which reduces the stability of use.

[0004] After searching, the Chinese patent publication number CN211878369U discloses a fixing device for processing a liquid crystal display screen. Although the device uses the limiting plates on both sides to limit and fix the two sides of the display screen, and the mounting frame can flexibly adjust the angle, thereby facilitating subsequent processing operations on the display screen, multiple steps are required to fix the LCD screen, which makes the operation more cumbersome and reduces the processing efficiency.

[0005] To this end, the present invention proposes a fixing device for processing a liquid crystal display screen, which can reduce the dependence of the fixing mechanism on an external power supply and can simplify the fixing steps of the existing device, thereby improving efficiency. Summary of the invention

[0006] In view of the deficiencies of the prior art, the present invention provides a fixing device for processing a liquid crystal display screen, which solves the problem that the clamping mechanism of the prior device proposed in the background art is highly dependent on an external power supply and the steps in the process of fixing the liquid crystal screen are relatively cumbersome.

The hydraulic mechanism is installed on the top of the bottom plate, and a frame is installed on the top of the hydraulic mechanism. A fixing mechanism is installed on the top of the frame. The hydraulic mechanism is used to lock the fixing mechanism. The four ends of the fixing mechanism are connected to the frame. The frame is used to limit the four ends of the LCD screen, and angle adjustment mechanisms are arranged at the bottom of the four ends of the frame. There are four angle adjustment mechanisms, and the four angle adjustment mechanisms are arranged vertically. A transfer mechanism is installed at the other end of the base plate, and the transfer mechanism includes a transverse driving mechanism. A lifting mechanism is arranged on one side of the transverse driving mechanism, and the lifting mechanism is used to adsorb the surface of the LCD screen to transfer it to the positioning mechanism.

The resistance can effectively restrain the upward movement of the piston rod, which helps to prevent the LCD screen from falling due to sudden external force. This helps to further stabilize the clamping block to clamp and fix the LCD screen, thereby improving the safety of the device.

[0015] Preferably, the longitudinal moving mechanism includes a third motor, and the third motor is installed on the top of one end of the beam by bolts.

[0016] The present invention provides a fixing device for processing a liquid crystal display screen, which has the following beneficial effects: (1) A fixing device for processing a liquid crystal display screen. The device improves processing efficiency by simplifying the process of fixing the liquid crystal display screen. In specific operation, it is only necessary to align the four ends of the liquid crystal display screen and embed them into the four-end slots of the frame, and then lower the liquid crystal display screen to the chassis. When the liquid crystal display screen contacts the chassis, the chassis will drive the cross bar to move downward. This movement of the cross bar acts on the first connecting rod through the second connecting rod, causing it to rotate. The rotation of the first connecting rod further drives the top clamping block to move toward the edge of the liquid crystal display screen, thereby achieving the engagement between the clamping block and the edge of the liquid crystal display screen, thereby fixing the liquid crystal display screen. The entire process reduces the steps required to fix the liquid crystal display screen, effectively improving processing efficiency.

[0017] (2) A fixing device for processing a liquid crystal display screen. When the weight of the liquid crystal display screen acts on the chassis, the chassis compresses the spring and pushes the piston rod downward. The piston rod then pushes the piston block inside the piston tube, causing the hydraulic oil at the upper end of the tube to move downward and enter the cavity below the partition through the small hole in the center of the partition. The excess hydraulic oil flows into the top of the piston block through the connecting pipe. If the liquid crystal display screen is suddenly lifted up by an external force, the clamping block transmits the force to the piston rod. Since the hole groove in the center of the partition is small, the resistance of the hydraulic oil increases when passing through, which effectively limits the upward movement of the piston rod, prevents the liquid crystal display screen from falling off due to external force, and ensures that the clamping block stably fixes the liquid crystal display screen.

[0018] (3) In the fixing device for processing a liquid crystal display screen, the bottom of the piston tube is rotatably connected to the ball at the top of the first support column, so that the angle of the frame can be freely adjusted. When the liquid crystal screen above the frame is adjusted to a suitable processing angle, the knob is turned to drive the push rod to move up and down, and then the top of the push rod is adjusted to support the bottom of the frame, so that the frame can maintain the angle, which is conducive to convenient processing.

[0019] (4) This kind of fixing device for processing liquid crystal display screens, for a heavy liquid crystal screen, by placing the liquid crystal screen on the surface of one end of the base, using the first motor to drive the first threaded rod to rotate, so that the lifting block moves downward, so that the bottom suction cup absorbs and fixes the liquid crystal screen, and then drives the liquid crystal screen to move upward; under the action of the second motor, the slider moves horizontally to adjust the position of the liquid crystal screen; finally, under the drive of the third motor, the crossbeam moves longitudinally to accurately position the liquid crystal screen above the positioning mechanism, thereby achieving auxiliary fixation and effectively reducing the workload of the operator.

[0020] This solves the problem that the clamping mechanism of the existing device is highly dependent on the external power supply and the steps in the process of fixing the liquid crystal screen are relatively complicated. BRIEF DESCRIPTION OF THE DRAWINGS

A longitudinal moving mechanism is arranged at one end of the transverse driving mechanism, and the longitudinal moving mechanism is installed on the top of the gantry 5.

[0025] The fixing mechanism includes a first connecting rod 208, four of which are provided, and a clamping block 209 is welded at one end of the top of the four first connecting rods 208. A groove is provided on the surface of the clamping block 209 for clamping the frame of the LCD screen 3. The middle of the first connecting rod 208 is rotatably connected to one end of the second connecting rod 210, and the other end of the second connecting rod 210 is rotatably connected to the end of a cross bar 211. Four cross bars 211 are provided, and a chassis 212 is welded between the four cross bars 211. The chassis 212 is used to support the bottom of the LCD screen 3. When the device is used, only The four ends of the LCD screen 3 need to be aligned with the four end slots of the frame 7, and then lowered to fix the LCD screen 3. When the LCD screen 3 is lowered and falls on the chassis 212, the chassis 212 will drive the cross bar 211 to move downward. While the cross bar 211 moves downward, it can pull the first connecting rod to rotate through the second connecting rod. While the first connecting rod rotates, it can drive the clamping block 209 at one end of the top to move, so that the clamping block 209 can be engaged with the edge of the LCD screen 3, so that the LCD screen 3 can be fixed, which greatly reduces the process of fixing the LCD screen 3 and is beneficial to improving the processing efficiency.

A hole groove is provided on the surface of the partition 218. The hydraulic pipe 206 and the connecting pipe 219 are filled with hydraulic oil. There are two connecting pipes 219. When the LCD screen is suddenly lifted upward by an external force, the clamping block will transfer the upward force to the piston rod. Since the hole groove in the center of the partition is small, the top end of the piston rod 213 is externally threaded. The top end of the piston rod 213 is connected to the internal thread of the adjusting block 214. A first spring 215 is provided between the adjustment block 214 and the frame 7. The first spring 215 is sleeved on the outside of the piston rod 213. When the weight of the LCD screen 3 is applied to the chassis 212, the chassis 212 will compress the spring downward and push the piston rod 213 downward. The piston rod 213 can push the piston block 216 inside the piston tube downward, so that the hydraulic oil at the upper end of the piston tube can be pushed downward, and the hydraulic oil inside the piston tube can pass through the hole groove in the center of the partition 218 into the cavity below the partition 218, so that the excess hydraulic oil inside the cavity at the bottom of the piston tube can enter the top of the piston block 216 through the connecting pipe 219. When the LCD screen 3 is suddenly lifted up by an external force, the clamping block 209 will transfer the upward force to the piston rod 213. Since the hole groove in the center of the partition 218 is small, when the piston rod 213 pulls the piston block 216 upward, the hydraulic oil in the cavity below the partition 218 has a small flow channel when passing through the hole groove in the center of the partition 218, resulting in a large resistance to the upward movement of the piston block 216. This resistance can effectively restrain the piston rod 213 from moving upward, which is beneficial to prevent the LCD screen 3 from falling due to being suddenly lifted up by an external force, and further helps the clamping block 209 to further stably clamp and fix the LCD screen 3.
