Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of film packaging equipment, and particularly relates to a packaging equipment and method for liquid crystal display screen film covering. BACKGROUND

[0002] The liquid crystal display screen film packaging equipment is a device for film covering in the production process of liquid crystal display screens to protect the screen surface from scratches, contamination and damage. The device is usually equipped with precise film bonding technology, which can uniformly bond the protective film on the screen surface, while ensuring that the film is bubble-free and wrinkle-free. It is an important part of the production process of liquid crystal display screens, which helps to improve the appearance quality of the product and the protection during transportation.

[0003] The Chinese patent with application number 202510835077.9 discloses an LCD liquid crystal display screen film covering protection equipment, which further comprises a relaxation feeding mechanism installed on the top of the transmission mechanism. The patent extends the length of the protective film between the feeding cylinder and the winding cylinder by installing the relaxation feeding mechanism, so that the extended protective film can recover and avoid shrinking after being bonded on the display screen, thereby avoiding the situation that the edges of the display screen are difficult to be protected. In addition, the relaxation feeding mechanism uses an adaptive structure to solve the problem that the protective film cannot be bonded with the display screen as a whole when the winding cylinder and the feeding cylinder have different diameters and different amounts of material. By installing the low-extension anti-wrinkle mechanism, the relaxed protective film remains horizontal, wrinkle-free and in a low-extension state, effectively solving the problems of tilting and wrinkling of the relaxed protective film. At the same time, by installing the relaxation feeding mechanism, the quality of the bonded protective film is ensured while the extension problem is solved.

[0004] If the liquid crystal display screen is moved by a conveyor belt for film covering, the direct pressing method may cause quality problems such as film bubbles and poor bonding. At the same time, the liquid crystal display screen is protruding on the conveyor belt, which is easy to cause damage to the display screen. The roller pressing method is difficult to quickly and efficiently cycle the film covering operation, and often needs to re-grip the film after pressing the film on one display screen, otherwise the protective film is easy to fall off, which leads to low film covering efficiency. At the same time, if the display screen is not closely bonded with the roller during the roller pressing film covering, it may cause poor bonding or quality problems such as bubbles in some areas.

[0021] Compared with the prior art, the present application has the following beneficial effects:

[0022] (1) The present application can improve the firmness of the film covering, and quickly switch between film covering and clamping, thereby greatly improving the efficiency of the cycle film covering, through the cooperation of the film covering pushing mechanism and the positioning box groove and the film covering box groove. Specifically, during film covering packaging, the display screen body is first clamped on the clamping mechanism. Due to the clamping between the two rubber roller bodies and the magnetic connection by the magnetic block, the protective film at one end of the film covering roller can be clamped by the first pushing roller and the second pushing roller. After clamping, the second pushing roller is pulled away from the film covering roller to the end, and the first pushing roller also moves, at this time the protective film is pulled apart by a distance to wait to be covered, the action of the film covering pushing mechanism is clamping; then, rotate the film covering box groove, make the film covering box groove be inserted above the positioning box groove, at this time the pulled film is above the display screen body, and the first pushing roller is below the protective film and the second pushing roller is above the protective film, at this time, by rotating the handle of the second pushing roller, the rubber roller body of the second pushing roller rotates to tighten and press the end of the protective film, so that one hand rotates the second pushing roller to press the protective film with the second pushing roller, and the other hand pushes the first pushing roller, since the first pushing roller is above the protective film, the first pushing roller can quickly make the protective film adhere to the surface of the display screen body and the positioning box groove, at this time the action of the first pushing roller is film covering, and the action of the second pushing roller is clamping and pressing; finally, by continuing to push the second pushing roller, due to the rotating effect of the rubber roller body of the second pushing roller, the second pushing roller can be pressed and adhered again, until the second pushing roller is pushed to the end and the first pushing roller continues to clamp the protective film, so as to perform the next cycle; at this time, the firmness of the film covering is realized by twice pressing and adhering, and the new protective film at one end is clamped at the same time as the film covering, so as to quickly switch between film covering and clamping, thereby greatly improving the efficiency of the cycle film covering.

[0023] (2) The display screen body can be in a plane with the surface of the positioning box groove at the film covering position, preventing the display screen body from being covered in a protruding state, thereby reducing the risk of damage to the display screen body, and the side of the display screen body that has not been covered can be in a raised state during the film covering process, ensuring that the display screen body can be closely attached to the rubber roller body of the film pushing mechanism, thereby greatly improving the film covering quality. Specifically, when the display screen body is clamped, the display screen body protrudes from the surface of the positioning box groove. Through the structural design of the clamping mechanism, the sliding block can be passively lifted adaptively under external force, and the display screen body clamped in the clamped groove can be simultaneously and synchronously rotated and inclined through the rotating connection of the rotating cylinder and the rotating groove. Therefore, when the rubber roller body of the film pushing mechanism is pressed against the film, the position of the display screen body in contact with the rubber roller body can always be in a plane with the surface of the positioning box groove, preventing the display screen body from being covered in a protruding state, thereby reducing the risk of damage to the display screen body. Meanwhile, based on the structure of the clamping mechanism, the V-shaped adjusting rod of the bidirectional adjusting mechanism is designed to form a lever action. When one end of the display screen body is pressed down, the other end of the V-shaped adjusting rod is also pressed down, and the other end of the V-shaped adjusting rod is raised through the lever principle to push the other end of the display screen body. Therefore, the side of the display screen body that has not been covered can be in a raised state during the film covering process, ensuring that the display screen body can be closely attached to the rubber roller body of the film pushing mechanism, thereby greatly improving the film covering quality.

[0024] (3) The mounting structure design of the film covering roller can continuously cover the display screen body without interference, and also facilitates quick replacement of new film covering rollers. Specifically, by pulling the pull rod of the limiting mechanism, the limiting rod at the end of the film covering roller can be quickly contacted and limited, thereby facilitating quick replacement of new film covering rollers. Since the film covering roller is installed between the positioning box groove and the film covering box groove, the film covering roller can be quickly replaced regardless of whether the positioning box groove and the film covering box groove are in an open or plugged state, and is not interfered by external components, thereby continuously covering the display screen body.

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. Of course, the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0037] Although the steps in this invention are arranged by reference numerals, this is not intended to limit the order of the steps. Unless the order of the steps is explicitly stated or the execution of a step requires other steps as a basis, the relative order of the steps can be adjusted. It is understood that the term "and / or" as used herein refers to and covers any and all possible combinations of one or more of the associated listed items.

[0038] Example

[0039] like Figures 1-9 As shown, a packaging device for laminating liquid crystal displays includes a positioning slot 100, a clamping mechanism 200 symmetrically installed inside the positioning slot 100 for clamping the display body 300; a laminating slot 700 is rotatably connected to one side of the positioning slot 100; and a laminating roller 400 is rotatably connected to the side of the positioning slot 100 near the laminating slot 700.

[0040] The inner bottom of the film-coating box 700 is symmetrically provided with slides 720 on both sides, and the two slides 720 are slidably connected to the film-coating pushing mechanism 800.

[0041] The present invention, through the cooperation of the film-coating pushing mechanism 800, the positioning box groove 100, and the film-coating box groove 700, can not only improve the firmness of film coating, but also quickly switch between film coating and clamping, thereby greatly improving the efficiency of cyclic film coating; a detailed description will follow.

[0042] Further, the film-coating pushing mechanism 800 includes two identical first pushing rollers 810 and second pushing rollers 820; the first pushing roller 810 includes a rubber roller body 811, with sliders 821 fixedly connected to both ends of the rubber roller body 811, and a limiting groove 721 provided on the inner side of the slide rail 720; the slider 821 is located in the limiting groove 721 and slidably connected to the limiting groove 721; a rotating rod 812 is fixedly connected to the slider 821, and a handle 822 is fixedly provided at one end of the rotating rod 812; the rotating rod 812 is rotatably connected to the rotating hole 831 in the middle of the magnetic block 830; the magnetic block 830 is fitted into the slide rail 720 and slides on the slide rail 720.

[0043] When the present invention is used for lamination packaging, the display screen body 300 is first clamped onto the clamping mechanism 200. Due to the clamping between the two rubber roller bodies 811 and the magnetic connection through the magnetic block 830, one end of the protective film of the lamination roller 400 can be clamped by the first push roller 810 and the second push roller 820. After clamping, the second push roller 820 is pulled away from the lamination roller 400 to the end, and the first push roller 810 also moves accordingly. At this time, the protective film is pulled apart a certain distance to await lamination. The pushing mechanism 800 functions as a clamping mechanism. Next, the coating box groove 700 is rotated so that it is inserted above the positioning box groove 100. At this point, the pulled-out protective film is positioned above the display screen body 300, while the first pushing roller 810 is below the protective film and the second pushing roller 820 is above it. By rotating the handle of the second pushing roller 820, while maintaining the magnetic clamping function, the rubber roller body 811 of the second pushing roller 820 rotates to wrap around the end of the protective film. The protective film is pressed and tightened by rotating the second push roller 820 with one hand, while the first push roller 810 is pushed with the other hand. Since the first push roller 810 is above the protective film, it can quickly adhere the protective film to the surface of the display screen body 300 and the positioning box groove 100. At this time, the first push roller 810 acts as a film covering, and the second push roller 820 acts as a clamping and pressing. Finally, by continuing to push the second push roller 820... The second push roller 820 is pushed to the end. Due to the rotation effect of the rubber roller body 811 of the second push roller 820, the second push roller 820 can be pressed and bonded for a second time until the second push roller 820 is pushed to the end and the first push roller 810 continues to hold the protective film, thus starting the next cycle. At this time, the film is firmly bonded through the second pressing and bonding, and at the same time as filming, it is simultaneously switched to holding one end of the new protective film. The rapid switching between filming and holding greatly improves the efficiency of cyclic filming.

[0044] It is worth noting that the protective film winding direction of the coating roller 400 of the present invention is... Figure 2 As shown in the counterclockwise direction, when the protective film is pulled open and the laminating box 700 is inserted above the positioning box 100, the protective film and the display screen body 300 still have a certain distance to prevent adhesion before the roll lamination.
