Description

Technical Field

[0001] This invention relates to the field of display screen film application, and more specifically, to an automated display screen film application production line. Background Technology

[0002] A display screen is an electronic output device used to display images, videos, or text information. It is widely used in consumer electronics, industrial control, medical equipment, automotive systems, and other fields. In the current production process of displays, a film-applying process is required. This mainly includes applying film to the long side of the display screen, screwing, handling, applying film to the short side, and outputting the material. Currently, existing display screen handling devices mainly use two sets of single adsorption methods in conjunction with linear motors to move the display screen. During this operation, if the adsorption of the display screen is unstable and cannot be adaptively adjusted, the display screen is prone to displacement due to inertia when in motion, which leads to a decrease in production efficiency and has certain drawbacks.

[0003] For example, the Chinese invention patent application (application number: CN202411737295.0) discloses a "loading and unloading device for a display screen tray," which states that: With the continuous development of electronic intelligent devices, more and more electronic products are being accepted by the public, and people's demand for various electronic products is increasing day by day. As an indispensable component of electronic products, displays are also constantly being updated and iterated to meet the needs of different applications. To adapt to displays of various specifications and sizes, the dimensions of display screen trays have also become diversified. With the continuous growth in demand for displays, improving the production efficiency of display panel processing equipment has become particularly important. However, traditional loading and unloading mechanisms usually use a single conveyor belt for continuous loading and unloading, making material preparation impossible. This greatly limits the improvement of production efficiency, leading to a waste of time and personnel costs. Therefore, there are areas for improvement; the aforementioned patent can corroborate the deficiencies of the existing technology.

[0004] Therefore, we have made improvements to this and proposed an automated screen protector application production line. Summary of the Invention

[0005] The purpose of this invention is to address the issue that existing display screen handling devices primarily rely on two single adsorption methods combined with a linear motor to handle the display screen. However, during operation, if the display screen's adsorption is unstable and it is in motion, it is prone to displacement due to inertia, which in turn reduces production efficiency.

[0006] To achieve the above-mentioned objectives, the present invention provides an automated screen protector application production line to improve the aforementioned problems.

[0007] The application is as follows: The device includes a linear motor installed in the attachment equipment. The upper surface of the linear motor is distributed with several telescopic components. The side wall of the telescopic components is provided with an adsorption component for drawing and releasing gas. The telescopic components are symmetrically arranged with outwardly extending toothed forks inside. A fixing module for adsorbing the display screen by negative pressure is provided on the side of the telescopic components opposite to the adsorption components.

[0008] As a preferred technical solution of this application, the fixing module includes a negative pressure plate fixedly installed on the top of the tooth fork, and an adsorption membrane is sleeved on the top of the negative pressure plate.

[0009] As a preferred technical solution of this application, the fixing module includes a support plate fixedly installed on the top of the fork, an L-shaped mounting bracket evenly distributed at the bottom of the fork, and an adjustment component disposed between the two sets of mounting brackets.

[0010] As a preferred technical solution of this application, the adjustment component includes a central air tube and a circular array of rubber arc plates on its outer side. Several air holes are opened through the inner side of the rubber arc plates. A vertical tube is arranged below the rubber arc plates, and the bottom of the vertical tube is connected to the outer side of the central air tube. Horizontal tubes in an L-shape are symmetrically arranged on the left and right sides of the vertical tube. The tops of the horizontal tubes and the vertical tubes are connected to the air holes in the middle of the rubber arc plates.

[0011] As a preferred technical solution of this application, a fixing frame is provided below the two sets of horizontal tubes.

A connecting piece is sleeved on the telescopic end of the electric push rod, and the electric push rod is connected to the inner side of the rubber arc plate through the connecting piece. A rubber strip is fixedly installed on the outer side of the rubber arc plate.

[0012] As a preferred technical solution of this application, one end of the central trachea is open, and an end plate is sealed to the open end of the central trachea. A second end shaft is fixedly installed on the outside of the end plate, and a connecting hose is provided on the inside of the central trachea. One end of the connecting hose passes through the end plate and the second end shaft and is connected to the adsorption component.

[0013] As a preferred technical solution of this application, an inner shaft is provided at one end of the central trachea cavity near the end plate. A wavy guide groove is provided on the outer side of the inner shaft. Fixed sleeves are provided at intervals on one side of the inner shaft.

[0015] As a preferred technical solution of this application, an internal gear disk is fixedly installed between the two sets of mounting brackets. A turntable is sleeved inside the internal gear disk. A gear is provided on the side wall of the turntable, and the gear meshes with the inner side of the internal gear disk.

[0016] As a preferred technical solution of this application, the top of the turntable is symmetrically provided with support rods, one set of the support rods is sleeved with the first end shaft, and the other set of the support rods is fixedly connected to the second end shaft.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: In the scheme of this application: 1. To address the problem in existing technologies where the display screen cannot adaptively adjust during transport, leading to displacement due to inertia even in an unstable fixed state, this application utilizes an adjustment component. This component, along with a central air tube and an array of rubber arc plates on its outer side, can be used in conjunction with an adsorption component to adsorb the display screen. Simultaneously, by changing the extension length of the telescopic rod and using a guide groove, the central air tube is rotated. This can be combined with an electric push rod and different rubber arc plates to adaptively adjust the display screen's position. Furthermore, a drive motor, gears, and an internal gear disc facilitate the rotation of the rubber arc plates, thereby adjusting the display screen's angle and achieving multi-angle adaptive adjustment.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0021] As described in the background section, existing display screen handling devices mainly use two sets of single adsorption methods in conjunction with linear motors to handle the display screen. During this operation, if the display screen adsorption is unstable and it is in motion, the display screen is prone to displacement due to inertia, which leads to a reduction in production efficiency.

[0022] To address this technical problem, the present invention provides an automatic screen protector application production line, which is applied to a self-adjusting display transport device.

[0023] For details, please refer to Figures 1-12 The automatic screen protector application production line specifically includes a linear motor 1 installed in the application equipment. Several telescopic components 2 are distributed on the upper surface of the linear motor 1. The telescopic components 2 are belt-type reciprocating telescopic parts. Adsorption components 3 for extracting and releasing gas are provided on the side wall of the telescopic components 2. Outwardly extending toothed forks 4 are symmetrically arranged inside the telescopic components 2. Fixing bolts 7 for installation are provided through the bottom of the toothed forks 4. The reciprocating telescopic parts realize the reciprocating telescopic movement of the two sets of toothed forks 4. A fixing module for adsorbing the screen protector by negative pressure is provided on the side of the telescopic components 2 opposite to the adsorption components 3.

[0024] The automatic screen protector application production line provided by this invention uses an adjustment component, with a central air pipe inside the adjustment component and rubber arc plates arranged in an array on its outer side, to adsorb the screen. At the same time, by changing the extension length of the telescopic rod and cooperating with the guide groove, the central air pipe is rotated. At this time, an electric push rod can be used and different rubber arc plates can be selected to adaptively adjust the position of the screen. Meanwhile, the drive motor, in conjunction with gears and an internal gear plate, facilitates the rotation of the rubber arc plates, thereby facilitating the adjustment of the screen angle and realizing multi-angle adaptive adjustment.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An automatic screen protector application production line includes a fixed module comprising a negative pressure plate 5 fixedly installed on the top of a toothed fork 4, an adsorption membrane 6 sleeved on the top of the negative pressure plate 5, and air grooves provided in the middle and on the outer side of the adsorption membrane 6, and the air grooves being connected to the air inlet and outlet ends of the adsorption assembly 3 through an external hose. In use, the adsorption assembly 3, in conjunction with the external hose, evacuates the gap between the inner side of the negative pressure plate 5 and the adsorption membrane 6 and the interior of the adsorption membrane 6, thereby achieving a negative pressure adsorption effect. Working principle: In use, the tooth fork 4 is first extended by the telescopic component 2, so that the negative pressure plate 5 installed on the top of the tooth fork 4 comes into contact with the bottom of the display screen. At this time, the adsorption component 3 is activated. Through the adsorption component 3 and the external hose, a vacuum is drawn into the gap between the inner side of the negative pressure plate 5 and the adsorption membrane 6 and the inside of the adsorption membrane 6. At this time, the bottom of the display screen is adsorbed and fixed under negative pressure. After adsorption is completed, the adsorbed display screen can be moved by the linear motor 1.

[0029] Example 2, please refer to Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 The fixed module includes a support plate 8 fixedly installed on the top of the tooth fork 4, an L-shaped mounting bracket 9 evenly distributed at the bottom of the tooth fork 4, and an adjustment component 10 disposed between the two sets of mounting brackets 9. The support plate 8 disposed on the top of the tooth fork 4 is used to support the display screen, and the mounting bracket 9 is used to connect the adjustment component 10 and the tooth fork 4.

[0030] The regulating component 10 includes a central air tube 1001 and a circular array of rubber arc plates 1004 on its outer side. Several air holes 1005 are opened through the inner side of the rubber arc plate 1004. A vertical tube 1007 is arranged below the rubber arc plate 1004, and the bottom of the vertical tube 1007 is connected to the outer side of the central air tube 1001. The outer side of the vertical tube 1007 is equipped with an electric valve. Horizontal tubes 1006 in an L-shape are symmetrically arranged on the left and right sides of the vertical tube 1007. The two sets of horizontal tubes 1006 are connected to the vertical tube 1007. The tops of the horizontal tubes 1006 and the vertical tubes 1007 are connected to the air holes 1005 in the middle of the rubber arc plate 1004. The remaining air holes 1005 are connected to the adsorption component 3 through external hoses. The rubber arc plate 1004, together with the air holes 1005, horizontal tubes 1006 and vertical tubes 1007, facilitates gas delivery.

[0031] A fixing frame 1008 is provided below the two sets of horizontal tubes 1006. Hanging rings extend from both ends of the top of the fixing frame 1008 and are suspended from the outside of the horizontal tubes 1006. Electric push rods 1009 are evenly fitted onto both sides of the fixing frame 1008 parallel to the horizontal tubes 1006. Connecting pieces are fitted onto the telescopic ends of the electric push rods 1009, and the electric push rods 1009 are connected to the inner side of the rubber arc plate 1004 via the connecting pieces. The electric push rods 1009 facilitate the pushing of the edge of the rubber arc plate 1004. The movement allows it to contact the bottom surface of the display screen. By changing the extension length of the electric push rods 1009 on both sides of the horizontal tube 1006, it can be adapted to different scenarios. Rubber strips 1010 are fixedly installed on the outer side of the rubber arc plate 1004. The other end of some rubber strips 1010 is fixedly connected to the outer side of the horizontal tube 1006, and the other end of some rubber strips 1010 is fixedly connected to the outer side of the vertical tube 1007. The rubber strips 1010 facilitate the reset and limit of the electric push rods 1009.

[0032] One end of the central trachea 1001 is open, and an end plate 1018 is sealed to the open end of the central trachea 1001. A second end shaft 1019 is fixedly installed on the outside of the end plate 1018. A connecting hose 1017 is provided on the inside of the central trachea 1001. One end of the connecting hose 1017 passes through the end plate 1018 and the second end shaft 1019 and is connected to the adsorption assembly 3.

[0033] An inner shaft 1011 is provided at one end of the inner cavity of the central trachea 1001 near the end plate 1018. An array of mounting shafts 1012 are installed at the outer end of the inner shaft 1011 away from the end plate 1018. The inner shaft 1011 is fixedly connected to the inner side of the central trachea 1001 via the mounting shafts 1012. A wavy guide groove 1013 is provided on the outer side of the inner shaft 1011. Fixed sleeves 1014 are spaced apart on one side of the inner shaft 1011. A right-angled telescopic rod 1015 extends outward from the inner side of the fixed sleeve 1014. The other end of the fixed sleeve 1014 is fixedly connected to the inner side of the end plate 1018. A return spring 1016 is fixedly installed at one end of the telescopic rod 1015, and the telescopic rod 1015 is connected to the fixed sleeve 1018 via the return spring 1016. The inner wall of the fixed sleeve 1014 is fixedly connected, and the telescopic rod 1015 matches the guide groove 1013. The shorter end of the telescopic rod 1015 extends to the inner side of the guide groove 1013. When the telescopic rod 1015 extends or retracts under the adjustment of the air pressure inside the fixed sleeve 1014, the shorter end of the telescopic rod 1015 slides along the guide groove 1013, thereby driving the central air tube 1001 to rotate around the end plate 1018, thereby driving the rubber arc plates 1004 arrayed on the outer side of the central air tube 1001 to rotate. At this time, the electric push rods 1009 symmetrically distributed on the inner side of the rubber arc plate 1004 are coordinated to extend different lengths according to different rotation angles of the rubber arc plate 1004, thereby facilitating the change of the position of the rubber arc plate 1004 and the display.

[0034] A first end shaft 1002 is fixedly installed at one end of the central air tube 1001 opposite to the end plate 1018. A quick connector 1003 is fixedly installed on the outside of the first end shaft 1002. The inside of the quick connector 1003 passes through the first end shaft 1002 and communicates with the central air tube 1001. The other end of the quick connector 1003 is connected to the adsorption assembly 3 through a hose. The central air tube 1001 is connected to the adsorption assembly 3 through the quick connector 1003 and the hose, which facilitates the extraction and release of gas into the interior of the central air tube 1001.

[0035] An internal gear disk 1020 is fixedly installed between two sets of mounting brackets 9. A turntable 1021 is sleeved inside the internal gear disk 1020. The cross-section of the turntable 1021 is I-shaped. A gear 1024 is provided on the side wall of the turntable 1021, and the gear 1024 meshes with the inner side of the internal gear disk 1020. A drive motor 1023 is provided on the top of the gear 1024.

[0036] The top of the turntable 1021 is symmetrically provided with support rods 1022. One set of support rods 1022 is sleeved with the first end shaft 1002, and the other set of support rods 1022 is fixedly connected to the second end shaft 1019.

[0037] Working principle: In use, the telescopic component 2 extends the tooth fork 4 and the support plate 8 to the bottom of the display screen, so that the top of the rubber arc plate 1004 contacts the bottom of the display screen. At this time, the adsorption component 3, through the external hose and quick connector 1003, evacuates the three sets of central air tubes 1001, thereby forming a negative pressure inside the corresponding vertical tube 1007, horizontal tube 1006 and the air hole 1005 connected to them. Thus, the display screen is initially positioned through some of the air holes 1005. At this time, the electric push rods 1009 symmetrically arranged on both sides of the vertical tube 1007 and horizontal tube 1006 are activated. The electric push rods 1009 push the rubber arc plate 1004 to rotate, so that the side of the rubber arc plate 1004 continuously contacts the bottom of the display screen until the display screen is fully adsorbed by negative pressure through the air holes 1005 on both sides of the rubber arc plate 1004. The display can then be transported by linear motor 1 in conjunction with telescopic component 2. If the display shifts during transport, the position of the shift can be detected by the detection component on the top of telescopic component 2. Then, based on the feedback, drive motor 1023 is started. Drive motor 1023 rotates turntable 1021 by gear 1024 installed at its output end and under the limit of internal gear plate 1020. Then, the support rod 1022 symmetrically installed on the top of turntable 1021 drives the central air tube 1001 to rotate, thereby adjusting the angle of the display screen. Next, through the adsorption component 3 and the connecting hose 1017 connected to it, gas is repeatedly delivered and extracted into the fixed sleeve 1014. Under the action of air pressure, the telescopic rod 1015 is driven to reciprocate. When the telescopic rod 1015 reciprocates, it will slide along the guide groove 1013. When the telescopic end extends to the farthest end or is completely retracted, the telescopic rod 1015 moves to the end of the guide groove 1013. This process is repeated. With the continuous movement of the telescopic rod 1015, the inner shaft 1011 can be driven to rotate, which in turn drives the central air tube 1001 to rotate. While the central air tube 1001 is rotating, the corresponding electric push rod 1009 needs to be activated, so that the electric push rod 1009 on the side closer to the central air tube 1001 extends and simultaneously retracts another set of electric push rods 1009, thereby adapting to the rotating central air tube 1001, so that when the central air tube 1001 drives the display screen to move a short distance through the rubber arc plate 1004, it always maintains a negative pressure connection. If long-distance movement is required, a set of adjustment components 10 can be activated to repeat the above steps, while the remaining adjustment components 10 maintain the adsorption strength. Then, by utilizing the extensibility of the rubber arc plate 1004, the display screen is continuously moved short distances. Through alternating control, long-distance movement can be achieved.
