Description

Technical Field

[0001] This utility model relates to the field of display screen manufacturing technology, specifically to a fixing device for the production of anti-glare display screens. Background Technology

[0002] A display screen is a device component used to display visual information such as images and text. It is an important interface for electronic devices to output information to users. In the anti-glare spraying process of display screen production, in order to ensure the spraying effect of the display screen, it is necessary to prevent the display screen from moving, so a fixing device is required.

[0003] A Chinese patent with authorization announcement number CN119527885A discloses a display substrate transfer and clamping device for display production, including a conveyor belt, a moving component mounted on the conveyor belt, and a fixing component mounted on the conveyor belt; a second telescopic cylinder rises, a piston block moves upward inside a suction cup, sucking up the air inside the suction cup, while an air pump draws air, inflating the protective air cushion, making it more secure to the display substrate; a gear valve rotates, opening the gear valve, and the gas inside the protective air cushion is delivered to the suction cup, which slowly releases the display substrate. This invention reasonably solves the problem that most transfer devices use suction cups for fixing, resulting in weak suction during the transfer process.

[0004] However, the above-mentioned device still has some problems. In practical applications, it is impossible to adjust the angle of the suction cup to adapt to the curvature of the display screen. This has little impact on flat display screens, but for curved display screens, the contact will not be tight, resulting in the inability to perform stable fixing operations on the display screen and affecting the spraying effect of the display screen. Therefore, in order to solve the above problems, an anti-glare display screen production fixing device is proposed. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a fixing device for the production of anti-glare display screens.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: An anti-glare display screen production fixing device of this utility model includes a workbench. A vacuum chamber is installed on the top side of the workbench. Support rods are installed at both ends of the top side of the vacuum chamber. Mounting seats are installed at the top of each support rod. A connecting block is installed inside the mounting seat via a pin. A connecting plate is installed on the top side of the connecting block. Two suction cups are installed at both ends of the top side of the connecting plate. A mounting plate is installed on one side of the connecting plate. A support seat is installed on the bottom side of the mounting plate. A rotating shaft is rotatably installed inside the support seat. A support plate is installed on one side of the mounting seat. A threaded rod is movably installed inside the support plate. The top end of the threaded rod is rotatably installed inside the rotating shaft. A handle is installed at the bottom end of the threaded rod. By rotating the handle, the threaded rod is rotated. With the cooperation of the rotating shaft, the mounting plate drives the connecting plate to move inside the mounting seat, thereby adjusting the angle of the suction cups. This allows the suction cups to better adapt to the curved surface of the display screen and improves the stability of fixing the display screen.

[0007] Preferably, a telescopic rod is installed at the middle of the top side of the vacuum chamber, and a connecting plate is installed at the working end of the telescopic rod. Two suction cups are installed at both ends of the top side of the connecting plate. The bottom sides of both suction cups are connected to connecting pipes, and one end of each connecting pipe is connected to the vacuum chamber. Through the action of the telescopic rod, the suction cups can be raised or lowered, so that the suction cups can fix both flat and curved displays, thus expanding the applicability of the device.

[0008] Preferably, an air extraction pipe is installed on one side of the vacuum chamber, and a vacuum pump is installed on the top side of the workbench. The input end of the vacuum pump is connected to the air extraction pipe, and the output end of the vacuum pump is connected to an output pipe. An air inlet pipe is connected to the other side of the vacuum chamber, and a valve is installed inside the air inlet pipe. When the vacuum pump is started, the air in the vacuum chamber is extracted through the air extraction pipe to form a negative pressure, which causes the suction cup to adhere to the display screen, thereby fixing the suction cup to the display screen.

[0009] Preferably, a fixed frame is installed on one side of the workbench, and a reciprocating motor is installed on the top side of the fixed frame. A screw is installed at the output end of the reciprocating motor. A sliding groove is opened inside the top side of the fixed frame, and a sliding block is slidably installed inside the sliding groove. A screw hole is opened inside the sliding block. One end of the screw passes through the screw hole and is rotatably installed inside the fixed frame. The reciprocating motor drives the screw to rotate, causing the sliding block to reciprocate within the sliding groove, thereby realizing the movement of the nozzle and facilitating the comprehensive spraying operation of the display screen.

[0010] Preferably, a cylinder is installed on the bottom side of the sliding block, a straight tube is installed on the actuating end of the cylinder, nine nozzles are equidistantly installed on the bottom side of the straight tube, a valve two is fitted on the outside of the nozzles, a delivery pipe is installed on one side of the middle end of the straight tube, and one end of the delivery pipe is connected to the external anti-glare coating. By the action of the cylinder, the height of the straight tube can be adjusted to adapt to the spraying operation of displays with different thicknesses and widths. At the same time, the valve two can control the coating area of ​​the nozzles to avoid waste of spraying coating.

[0011] Preferably, a control panel is installed on one side of the workbench, and the control panel is electrically connected to the electrical components inside the device, thereby enabling centralized control of the electrical components inside the device.

[0012] The advantages of this utility model are:

[0013] 1. The handle of this utility model drives the threaded rod to rotate. The threaded rod will rotate inside the rotating shaft. During the rotation, the threaded rod will move up and down along the support plate. When the threaded rod moves, under the action of the mounting base and the support base, the original linear motion tendency of the mounting plate will change to the motion around the pin shaft. The rotating shaft will rotate inside the support base. The arc motion of the mounting plate will drive the connecting plate to rotate inside the mounting base. The rotation of the connecting plate will realize the angle adjustment of the suction cup, so that it can better fit the surface of the curved display screen and improve the stability of fixing the display screen.

[0014] 2. The output end of the reciprocating motor of this utility model drives the screw to rotate. When the screw rotates, the sliding block reciprocates in the sliding groove. The sliding block drives the nozzle and other components to reciprocate, thereby achieving spraying coverage of different positions of the display screen, facilitating comprehensive spraying operations. The cylinder's actuating end drives the straight pipe to rise or fall, so that the nozzle is at a suitable spraying height to adapt to the spraying requirements of different display screen specifications. During the spraying process, the paint spraying of each nozzle can be controlled by operating valve two according to actual needs, precisely controlling the paint spraying area and avoiding paint waste.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-4 As shown, an anti-glare display screen production fixing device includes a workbench 1, a vacuum chamber 2 installed on the top side of the workbench 1, support rods 3 installed at both ends of the top side of the vacuum chamber 2, mounting bases 4 installed at the top of each support rod 3, a connecting block 5 installed inside the mounting base 4 via a pin, a connecting plate 6 installed on the top side of the connecting block 5, two suction cups 7 installed at both ends of the top side of the connecting plate 6, a mounting plate 8 installed on one side of the connecting plate 6, a support base 9 installed on the bottom side of the mounting plate 8, a rotating shaft 10 rotatably installed inside the support base 9, a support plate 11 installed on one side of the mounting base 4, a threaded rod 12 movably installed inside the support plate 11, the top end of the threaded rod 12 rotatably installed inside the rotating shaft 10, and a handle 13 installed at the bottom end of the threaded rod 12.

[0024] A telescopic rod 14 is installed at the middle of the top side of the vacuum chamber 2. A connecting plate 2 15 is installed at the working end of the telescopic rod 14. Two suction cups 2 16 are installed at both ends of the top side of the connecting plate 2 15. A connecting pipe 17 is connected to the bottom side of the suction cup 1 7 and the suction cup 2 16. One end of the connecting pipe 17 is connected to the vacuum chamber 2.

[0025] A suction pipe 18 is installed on one side of the vacuum chamber 2, and a vacuum pump 19 is installed on the top side of the workbench 1. The input end of the vacuum pump 19 is connected to the suction pipe 18, and the output end of the vacuum pump 19 is connected to an output pipe 20. An air inlet pipe 21 is connected to the other side of the vacuum chamber 2, and a valve 22 is installed inside the air inlet pipe 21. During operation, in practical applications, the angle of the suction cup 7 cannot be adjusted to adapt to the curvature of the display screen. This has a smaller impact on flat display screens, but for curved display screens, it results in loose contact, making it impossible to stably fix the display screen, thus affecting the coating effect. When the operator rotates the handle 13, the handle 13 drives the threaded rod 12 to rotate. The threaded rod 12 will rotate inside the support plate 11 and the rotating shaft 10. During the rotation, the threaded rod 12 will move up and down along the support plate 11. When the threaded rod 12 moves, under the action of the mounting base 4 and the support base 9, the original linear motion tendency of the mounting plate 8 will change to the motion around the pin shaft. The rotating shaft 10 will rotate inside the support base 9. The arc motion of the mounting plate 8 will drive the connecting plate 6 to rotate inside the mounting base 4. The rotation of the connecting plate 6 realizes the angle adjustment of the suction cup 7, so that it can better fit the surface of the curved display screen and improve the stability of fixing the display screen.

[0026] For different types of displays, the height of suction cup 2 16 needs to be adjusted. Telescopic rod 14 starts to work, and its working end drives connecting plate 2 15 to rise or fall. Connecting plate 2 15 drives suction cup 2 16 to move, thereby adapting to the fixing requirements of flat or curved displays. That is, when fixing a flat display, suction cup 1 7 and suction cup 2 16 are on the same horizontal line. When fixing a curved display, the position height of suction cup 2 16 is lower than the position height of suction cup 1 7.

[0027] When it is necessary to fix the display screen, start the vacuum pump 19. The vacuum pump 19 extracts the air in the vacuum chamber 2 through the air extraction pipe 18 to form a negative pressure. Since the bottom sides of suction cup 1 7 and suction cup 2 16 are connected to the vacuum chamber 2 through the connecting pipe 17, under the action of negative pressure, suction cup 1 7 and suction cup 2 16 are adsorbed on the display screen to achieve a stable fixation of the display screen. Close valve 1 22 inside the air inlet pipe 21 to prevent air from entering the vacuum chamber 2 and maintain the negative pressure state. When the display screen is released, open valve 1 22 to allow air to enter the air inlet pipe 21.

[0028] Please see Figure 1 ,2 As shown in Figure 5, a fixed frame 23 is installed on one side of the workbench 1, a reciprocating motor 24 is installed on one side of the top of the fixed frame 23, a screw 25 is installed at the output end of the reciprocating motor 24, a sliding groove 26 is opened inside the top side of the fixed frame 23, a sliding block 27 is slidably installed inside the sliding groove 26, a screw hole is opened inside the sliding block 27, and one end of the screw 25 passes through the screw hole and is rotatably installed inside one side of the fixed frame 23.

[0029] A cylinder 28 is installed on the bottom side of the sliding block 27. A straight pipe 29 is installed on the working end of the cylinder 28. Nine nozzles 30 are equidistantly installed on the bottom side of the straight pipe 29. A valve 31 is fitted on the outside of the nozzles 30. A conveying pipe 32 is installed on one side of the middle end of the straight pipe 29. One end of the conveying pipe 32 is connected to the external anti-glare coating. A control panel 33 is installed on one side of the workbench 1. During operation, in the production of some outdoor displays, anti-glare coatings are applied to the surface of the display to reduce reflected light. The display after anti-glare treatment can clearly display content even under strong light. When spraying anti-glare coating on the display, the reciprocating motor 24 is started first. The output end of the reciprocating motor 24 drives the screw 25 to rotate. When rotating, the sliding block 27 reciprocates within the slide groove 26. The sliding block 27 drives the cylinder 28, straight pipe 29, and nozzle 30 mounted on its bottom side to reciprocate, thereby achieving spray coverage of different positions of the display screen and facilitating comprehensive spraying operations. Depending on the thickness and width of the display screen, the cylinder 28 can be adjusted. The actuating end of the cylinder 28 drives the straight pipe 29 to rise or fall, so that the nozzle 30 is at a suitable spraying height to meet the spraying requirements of different display screen specifications. During the spraying process, the paint spraying of each nozzle 30 can be controlled by operating the valve 2 31 according to actual needs, precisely controlling the paint spraying area and avoiding paint waste. External anti-glare paint is transported to the straight pipe 29 through the delivery pipe 32 and then sprayed onto the surface of the display screen through the nozzle 30.

[0030] Working principle: When fixing the curved display screen, the operator turns the handle 13, which drives the threaded rod 12 to rotate. The threaded rod 12 rotates inside the support plate 11 and the rotating shaft 10. During the rotation, the threaded rod 12 moves up and down along the support plate 11. When the threaded rod 12 moves, under the action of the mounting base 4 and the support base 9, the original linear motion of the mounting plate 8 is changed to a motion around the pin shaft. The rotating shaft 10 rotates inside the support base 9. The arc motion of the mounting plate 8 drives the connecting plate 6 to rotate inside the mounting base 4. The rotation of the connecting plate 6 realizes the angle adjustment of the suction cup 7, so that it can better fit the surface of the curved display screen and improve the stability of fixing the display screen.

[0031] For different types of displays, the height of suction cup 2 16 needs to be adjusted. Telescopic rod 14 starts to work, and its working end drives connecting plate 2 15 to rise or fall. Connecting plate 2 15 drives suction cup 2 16 to move, thereby adapting to the fixing requirements of flat or curved displays. That is, when fixing a flat display, suction cup 1 7 and suction cup 2 16 are on the same horizontal line. When fixing a curved display, the position height of suction cup 2 16 is lower than the position height of suction cup 1 7.

[0032] When it is necessary to fix the display screen, start the vacuum pump 19. The vacuum pump 19 extracts the air in the vacuum chamber 2 through the air extraction pipe 18 to form a negative pressure. Since the bottom sides of suction cup 1 7 and suction cup 2 16 are connected to the vacuum chamber 2 through the connecting pipe 17, under the action of negative pressure, suction cup 1 7 and suction cup 2 16 are adsorbed on the display screen to achieve a stable fixation of the display screen. Close valve 1 22 inside the air inlet pipe 21 to prevent air from entering the vacuum chamber 2 and maintain the negative pressure state. When the display screen is released, open valve 1 22 to allow air to enter the air inlet pipe 21.

[0033] When spraying anti-glare coating on the display screen, the reciprocating motor 24 is started first. The output end of the reciprocating motor 24 drives the screw 25 to rotate. When the screw 25 rotates, the sliding block 27 reciprocates in the slide groove 26. The sliding block 27 drives the cylinder 28, straight pipe 29 and nozzle 30 and other components installed on its bottom side to reciprocate, thereby achieving spray coverage of different positions of the display screen, which facilitates comprehensive spraying. According to the different thickness and width of the display screen, the cylinder 28 is adjusted. The action end of the cylinder 28 drives the straight pipe 29 to rise or fall, so that the nozzle 30 is at a suitable spraying height to meet the spraying needs of different specifications of display screens. During the spraying process, the coating of each nozzle 30 can be controlled by operating the valve 2 31 according to actual needs, so as to accurately control the coating spraying area and avoid coating waste. The external anti-glare coating is transported to the straight pipe 29 through the delivery pipe 32, and then sprayed onto the surface of the display screen through the nozzle 30.
