Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display screen processing, in particular to a liquid crystal display screen production edge grinding machine based on multi-station processing. Background Art

[0002] With the continuous advancement of liquid crystal display (LCD) technology, its application range is becoming increasingly widespread. From smartphones and tablets to large TV screens, the popularity and importance of LCD products are undeniably evident. Edge processing is a critical step in ensuring product quality during the LCD production process. To ensure the final product's excellent appearance and performance, the edges of the cut display screens must be polished to remove burrs and unevenness, while also ensuring smooth corners and a smooth surface finish.

[0003] However, after the edging process, effectively removing the fine particles, dust, and other impurities generated remains a challenge. If these residues are not properly handled, they can cause contamination during subsequent assembly and even scratch or damage the screen, severely impacting yield and user experience. Traditional cleaning methods, such as air blowing or manual wiping, struggle to completely remove all particles and are prone to secondary contamination. Wiping methods can also cause scratches due to friction between dust and impurities and the screen surface.

[0004] In order to solve the above problems, we propose an LCD display production edge grinding machine based on multi-station processing. This edge grinding machine integrates a multi-stage cleaning function, which can not only effectively remove residual stains, but also avoid the risk of scratches caused by contact to the greatest extent. Summary of the Invention

[0005] In order to overcome the shortcomings of using a single cleaning method such as blowing or manual wiping, which is difficult to completely remove all particles and easily causes scratches on the screen, the utility model provides a liquid crystal display production edge grinding machine based on multi-station processing. This edge grinding machine integrates a multi-stage cleaning function, which can not only effectively remove residual stains, but also avoid the risk of scratches caused by contact to the greatest extent.

[0006] Base comprises support, castor, and frame upper is provided with guide rail, and support and conveyer frames movable end contact site are provided with recoil spring or rubber cushion, and castor is arranged on the pin of base bottom four, to carry mobile handler location.

[0007] As a further preferred solution, the conveyor belt of the conveyor group is provided with equidistantly distributed strip blocks for placing liquid crystal display screens.

[0008] As a further preferred solution, the first roller and the second roller are specifically dust-sticking rollers that use static electricity to remove dust.

[0009] As a further preferred solution, the cleaning assembly includes a collection frame, which is slidably connected to the mounting block, a dust scraping frame is installed on the support frame, the bottom end of the dust scraping frame is in contact with the first roller, and a scraper is fixedly connected to the collection frame, and the scraper is in contact with the adjacent second roller.

[0010] As a further preferred solution, the polishing assembly includes a longitudinally symmetrical connecting frame, which is fixedly connected to the wiping plate, the connecting frame is fixedly connected to the polisher, the connecting frame is fixedly connected to the discharge tank, and the bottom outlet of the discharge tank is located at the edge of the polisher.

[0011] As a further preferred solution, a feed port for adjusting the polishing liquid is provided at the top of the discharge tank.

[0012] The utility model has the following advantages: the LCD screen is conveyed to the right by the conveying group, and when the LCD screen moves to the bottom of the cover plate, the cover plate moves downward to cover the upper side of the LCD screen, and the electric slide rail drives the grinder to move left and right to grind the front and back sides of the LCD screen. During the grinding process, the cover plate covers the upper side of the LCD screen to reduce the adhering dust and impurities. After the grinding is completed, the LCD screen continues to move to the right, and first uses the vacuum cleaner to quickly absorb most of the large particles of debris scattered on the work surface and the screen surface, and then uses the first roller and the second roller to further capture finer dust particles by using the electrostatic adsorption principle. Finally, the wiping plate is gently swept across the entire screen surface for final cleaning. In this way, not only can residual stains be effectively removed, but also the risk of scratches caused by contact can be avoided to the greatest extent. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following further describes the technical solution with reference to specific embodiments. It should be noted that terms such as "up," "down," "left," and "right" used herein to indicate directions refer only to the positions of the structures depicted in the corresponding drawings. Component numbers, such as "first" and "second," are used solely to distinguish the components being described and do not convey any sequential or technical meaning. References to "connected" and "coupled" in this application, unless otherwise specified, include both direct and indirect connections (couplings).

[0023] Example 1: A multi-station processing LCD production edge grinding machine, such as Figures 1-8 As shown, it includes a support base 1, a conveying group 2, a rodless cylinder 3, a sliding plate 31, a cover plate 4, an electric slide rail 5, a grinder 6, a support frame 7, a mounting block 71, a vacuum cleaner 8, a collecting container 9, a first roller 10, a second roller 11, a wiping plate 12, a cleaning component and a polishing component. The support base 1 is fixedly connected to the conveying group 2, and the conveying group 2 consists of a conveyor belt and two conveyor rollers. The left and right parts of the support base 1 are rotatably connected to the conveyor rollers, and a conveyor belt is sleeved between the left and right conveyor rollers. The conveyor belt of the conveyor group 2 is provided with equidistantly distributed strip blocks for placing LCD screens. The middle part of the support base 1 is fixedly connected to a front-to-back symmetrical rodless cylinder 3, and a sliding plate 31 is slidably connected between the front and rear rodless cylinders 3. The lower side of the sliding plate 31 is fixedly connected to a cover Plate 4, the front and rear parts of the cover plate 4 are fixedly connected to the electric slide rail 5, the electric slide rail 5 is slidably connected to the grinder 6, the right part of the support base 1 is fixedly connected to the support frame 7, the front and rear sides of the right part of the support frame 7 are fixedly connected to the mounting block 71, the left part of the support frame 7 is fixedly connected to the dust cleaner 8, the upper side of the dust cleaner 8 is connected to the collecting container 9, the right part of the support frame 7 is rotatably connected to the first roller 10, and the mounting block 71 is rotatably connected to the second roller 11.

[0024] When using this device, the staff will place the LCD screen that needs to be edged on the conveying group 2, and the conveying group 2 will drive the LCD screen to move to the right. When the LCD screen moves to under the cover plate 4, the conveying group 2 stops conveying the LCD screen. At this time, the rodless cylinder 3 controls the sliding plate 31 to slide downward, and the sliding plate 31 slides downward to drive the cover plate 4 to move downward to cover the upper side of the LCD screen, and the electric slide rail 5 and the grinder 6 will also move downward with the cover plate 4 to the front and back sides of the LCD screen. The electric slide rail 5 drives the grinder 6 to move left and right to grind the front and back sides of the LCD screen. During the grinding process, since the cover plate 4 covers the upper side of the LCD screen, it can reduce dust and impurities attached to the LCD screen. After the grinding is completed, the staff uses the rodless cylinder 3 controls the sliding plate 31 to slide upward, and the sliding plate 31 slides upward to drive the cover plate 4, the electric slide rail 5 and the grinder 6 to move upward. At this time, the conveying group 2 drives the LCD screen to continue to move to the right. When the LCD screen moves to the right, the vacuum cleaner 8 quickly absorbs most of the large particles of debris scattered on the work surface and the screen surface, and the absorbed impurities enter the collection container 9 for collection. The LCD screen continues to move to the right and contacts the first roller 10 and the second roller 11. The first roller 10 and the second roller 11 use the electrostatic adsorption principle to further capture finer dust particles. Finally, the wiping plate 12 gently brushes across the entire screen surface for final cleaning. In this way, not only can residual stains be effectively removed, but also the risk of scratches caused by contact can be avoided to the greatest extent.
