Description

Technical Field

[0001] This invention relates to the field of liquid crystal display assembly, specifically to an automatic assembly equipment for liquid crystal display modules. Background Technology

[0002] LCD screens are a type of flat panel display, primarily used in television and computer screens. Currently, LCD screens are trending towards being lighter, thinner, shorter, and smaller, thus placing stricter demands on their manufacturing processes. An LCD screen can be broadly divided into two parts: the LCD panel and the backlight system. These two parts need to maintain a high degree of parallelism and alignment before being bonded together with specialized adhesive. The metal frame is then installed after the adhesive has cured. In traditional backlight assembly stations, workers typically use simple tools to align and assemble the LCD panel and backlight system before applying the specialized adhesive. However, manual assembly presents several problems: due to the difficulty of manual assembly and the fatigue of workers, scratching the LCD panel during the positioning and assembly of the backlight panel can cause optical defects in the product.

[0003] To address the aforementioned issues, utility model patent CN2611938 discloses a tool for assembling a liquid crystal panel and a backlight panel. This technical solution simplifies the assembly process by flipping the panel and the flat plate together to attach the liquid crystal panel and the backlight panel. Furthermore, the positioning and alignment between the liquid crystal panel and the backlight panel are achieved through the cooperation between the magnetic latch and the protrusion.

[0004] However, the following problems remain unresolved in the above technical solutions: 1. Before assembling the LCD panel and backlight panel together, dust and other debris on their contact surfaces need to be cleaned. However, this technical solution does not include a cleaning component, making it impossible to clean the contact surfaces. 2. After the LCD panel and backlight panel are bonded together, a special adhesive needs to be applied to the edges where they contact each other. Before applying the adhesive, the sides of the LCD panel and backlight panel need to be cleaned. The above technical solution cannot clean the sides. 3. Because the above technical solution applies pressure to the entire backlight panel, it cannot remove air bubbles between the bonding surfaces. These air bubbles will greatly interfere with the display effect and significantly affect product quality. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an automatic assembly equipment for liquid crystal display modules, including a base, a pressing part hinged on the base, a track frame fixedly connected to the base, a sliding track fixedly connected to the track frame, an electric slider slidably connected to the sliding track, a retaining rail fixedly connected to the lower side of the electric slider, a limit block slidably connected to the retaining rail, a pressure roller slidably connected to the retaining rail and below the limit block, a downward pressure spring fixedly connected between the limit block and the pressure roller, and a cleaning part slidably connected to the right side of the electric slider on the sliding track, the cleaning part being connected to the electric slider by a push spring.

[0006] The clamping part includes a clamping frame that is hinged to the base. The main body of the clamping frame is U-shaped.

[0011] As a preferred technical solution of the present invention, a fixing buckle is fixedly installed on the lower right side of the clamping frame. When the clamping frame is in a horizontal state, a square groove is opened on the base corresponding to the position of the fixing buckle. A telescopic buckle is slidably inserted through the right side of the square groove. The part of the telescopic buckle located on the outside of the base is connected to the base through a buckle spring.

[0012] As a preferred embodiment of the present invention, the rail has a pin hole structure along its length, and a pin is provided in the pin hole. The pin hole on the rail is inserted into the limiting block through the pin, thereby positioning the position of the limiting block.

[0013] As a preferred embodiment of the present invention, two T-shaped rails, one horizontal and one vertical, are fixedly connected to the lower side of the base. Two positioning blocks are slidably connected to each T-shaped rail. An elastic telescopic rod is provided on the upper side of the positioning block.

[0031] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0032] See Figures 1-2 An automatic assembly device for LCD display modules includes a base 1, a pressing part 2 hinged to the base 1, a track frame 11 fixedly connected to the base 1, a sliding track 111 fixedly connected to the track frame 11, an electric slider 12 slidably connected to the sliding track 111, a retaining rail 121 fixedly connected to the lower side of the electric slider 12, a limiting block 13 slidably connected to the retaining rail 121, a pressure roller 14 slidably connected to the retaining rail 121 and below the limiting block 13, a downward pressure spring 131 fixedly connected between the limiting block 13 and the pressure roller 14, and a cleaning part 3 slidably connected to the sliding track 111 and to the right of the electric slider 12, the cleaning part 3 being connected to the electric slider 12 via a push spring 122.

[0033] The cleaning unit 3 of this invention cleans the upper and lower surfaces of the LCD panel and backlight panel using two sets of cleaning components 32. Each set of cleaning components 32 is equipped with a dust removal roller 322 and a cleaning roller 323, which can remove dust and wipe the upper and lower surfaces of the LCD panel and backlight panel, completely cleaning away dust and droplets and ensuring product quality. The pressure roller 14 of this invention applies pressure to the bonded LCD panel and backlight panel from left to right, squeezing out air bubbles in the middle of the bonding surfaces and preventing air bubbles from interfering with the image, effectively ensuring product quality. The cleaning block 22 of this invention, with a cleaning strip 226 fixedly installed on its upper side, can clean both sides of the LCD panel to facilitate subsequent adhesive application. Furthermore, the cooperation between the telescopic buckle 151 and the fixed buckle 213 of this invention allows the two to remain fixed after bonding, facilitating the subsequent installation and fixing of the frame on the left and right sides of the LCD panel and backlight panel.

[0034] See Figures 3-6 , Figure 8 The pressing part 2 includes a pressing frame 21 hinged to the base 1. The main body of the pressing frame 21 is U-shaped. Multiple sliding grooves 211 are provided on the inner side of the pressing frame 21. A cleaning block 22 is slidably connected in the sliding groove 211. A return spring 221 is fixedly connected to the right side of the cleaning block 22. The end of the return spring 221 away from the cleaning block 22 is fixedly connected to the pressing frame 21. The retaining rail 121 has a pin hole structure along its length. A pin is provided in the pin hole. The pin hole on the retaining rail 121 is inserted into the limiting block 13 through the pin, thereby positioning the position of the limiting block 13. A torsion spring is provided at the hinge point between the pressing frame 21 and the base 1. The torsion spring provides a tendency for the pressing frame 21 to move in the vertical direction.

[0035] See Figures 1-3The cleaning unit 3 includes a mounting bracket 31 that is slidably connected to the sliding rail 111 and connected to one end of the push spring 122. The main body of the mounting bracket 31 is inverted U-shaped, and its lower side is an elastic telescopic structure. Two sets of cleaning components 32 are rotatably connected to the lower side of the mounting bracket 31. The two sets of cleaning components 32 are arranged vertically, and a torsion spring is provided at the rotatable connection between them and the mounting bracket 31. The torsion spring ensures that the cleaning components 32 are always in a horizontal state when no external force is applied.

[0036] See Figure 1 , Figures 4-5 The cleaning component 32 includes mounting rods 321 rotatably connected to each end of the mounting frame 31. A dust removal roller 322 is slidably connected between the two mounting rods 321. A cleaning roller 323 is slidably connected between the two mounting rods 321 and to the right of the dust removal roller 322. Both the dust removal roller 322 and the cleaning roller 323 are connected to the mounting rods 321 by a return spring 324 located on their respective left sides.

[0037] See Figure 3 , Figure 7 The base 1 has two T-shaped rails 17 fixedly connected to its lower side, and two positioning blocks 18 are slidably connected to each T-shaped rail 17. The positioning blocks 18 are provided with elastic telescopic rods 181 on their upper sides. The T-shaped rails 17 are provided with pin hole structures on their sides. The pin holes on the T-shaped rails 17 are inserted into the positioning blocks 18 by pins, thereby positioning the positioning blocks 18. A pneumatic suction cup 19 is fixedly connected to the base 1 between the two positioning blocks 18.

[0038] See Figure 4 , Figure 6 A fixing buckle 213 is slidably installed on the lower right side of the pressing frame 21. The fixing buckle 213 is an elastic telescopic structure. The upper end of the fixing buckle 213 passes through the pressing frame 21. When the fixing buckle 213 is not in contact with the pressure roller 14, it is retracted inside the pressing frame 21. When the pressing frame 21 is in a horizontal state, a square groove 15 is provided on the base 1 corresponding to the position of the fixing buckle 213. A telescopic buckle 151 is slidably inserted on the right side of the square groove 15. The part of the telescopic buckle 151 located outside the base 1 is connected to the base 1 through a buckle spring 16.

[0039] The pressure roller 14 provided in this invention can apply pressure from right to left to the bonded liquid crystal panel and backlight panel, squeezing out the air bubbles in the middle of the bonding surfaces, preventing the air bubbles from interfering with the image, and effectively ensuring product quality.

[0040] Specifically, before starting the operation, the worker needs to position the LCD panel using the positioning block 18, and then fix the position of the LCD panel using the pneumatic suction cup 19. Then, according to the required pressure, the position of the limiting block 13 is adjusted by the pin holes on the rail 121. After the backlight is installed on the upper side of the cleaning block 22, the operation can begin. First, the electric slider 12 drives the pressure roller 14 to move to the right along the sliding rail 111. Under the action of the downward pressure spring 131, the pressure roller 14 begins to press the clamping frame 21. The clamping frame 21 drives the backlight on it to start rotating clockwise along the hinge point. The backlight on it follows its movement and begins to slowly contact the LCD panel. The clamping frame 21 continues to rotate until it is parallel to the base 1.

[0041] At this time, the backlight panel is in full contact with the LCD panel. Then, the upper end of the fixing buckle 213 on the clamping frame 21 contacts the pressure roller 14. The fixing buckle 213 is pressed down by the pressure roller 14 and extends out. The fixing buckle 213 contacts the telescopic buckle 151 and pushes the telescopic buckle 151 to the right. The fixing buckle 213 continues to move downward until it is disengaged from the telescopic buckle 151. Then, the telescopic buckle 151 rebounds under the action of the buckle spring 16 and clamps the clamping frame 21 in a horizontal position. During the rotation of the clamping frame 21, the cleaning part 3 moves to the right under the action of the pushing spring 122 to clean the LCD panel and the backlight panel. After cleaning, the electric slider 12 drives the rail 121 to move to the left to squeeze out the air bubbles between the LCD panel and the backlight panel.

[0042] See Figures 4-5 A fixing plate 325 is fixedly connected above the mounting rod 321 of the cleaning part 3 located on the upper side. A toggle plate 326 is rotatably connected to the side of the fixing plate 325 near the dust removal roller 322. A limit rod 327 is fixedly connected to the fixing plate 325 and located to the left of the toggle plate 326. A torsion spring is provided at the connection between the toggle plate 326 and the fixing plate 325.

[0043] See Figures 7-9 The cleaning block 22 includes a sleeve block 222 that slides in the slide groove 211. A wedge block 223 is slidably connected in the sleeve block 222. The end of the wedge block 223 located outside the sleeve block 222 has two inclined surfaces, one above the other. A waist-shaped groove 224 is provided on the lower side of the sleeve block 222. A guide rod 225 is fixedly connected to the lower side of the wedge block 223. The guide rod 225 passes through the waist-shaped groove 224 on the sleeve block 222. An inclined groove 212 is provided on the lower side wall of the slide groove 211. The lower end of the guide rod 225 passes through the inclined groove 212. When the sleeve block 222 moves to the right, the guide rod 225 pushes the wedge block 223 into the sleeve block 222 under the action of the inclined groove 212.

[0044] See Figure 9 A cleaning strip 226 is fixedly installed on the sleeve block 222 and located on the upper side of the wedge block 223. The cleaning strip 226 is slightly longer than the sleeve block 222.

[0045] The cleaning unit 3 of this invention cleans the two surfaces of the LCD panel and backlight panel that are attached to each other using two sets of cleaning components 32. Each set of cleaning components 32 is equipped with a dust removal roller 322 and a cleaning roller 323, which can remove dust and wipe the two surfaces of the LCD panel and backlight panel that are attached to each other, and can completely clean the dust and droplets on them, ensuring the quality of the product. The cleaning block 22 of this invention can clean both sides of the LCD panel through the cleaning strip 226 fixedly installed on its upper side, so as to facilitate the subsequent glue application work. In addition, the cooperation between the telescopic buckle 151 and the fixed buckle 213 of this invention can keep them fixed after they are attached, which facilitates the subsequent operation of installing and fixing the frame on the left and right sides of the LCD panel and backlight panel.

[0046] Specifically, when the electric slider 12 drives the rail 121 to move to the right, the mounting bracket 31 moves to the right along with the electric slider 12 under the action of the push spring 122. As the backlight panel rotates with the clamping frame 21, it comes into contact with the cleaning component 32 located on the upper side. The dust removal roller 322 and cleaning roller 323 on it remove dust and wipe the lower side of the backlight panel. Since a torsion spring is provided at the rotatable connection between it and the mounting bracket 31, it can automatically adapt to the tilt angle of the backlight panel. At the same time, the dust removal roller 322 and cleaning roller 323 on the cleaning component 32 located on the lower side remove dust and wipe the upper side of the LCD panel. Meanwhile, the toggle plate 326 contacts the guide rod 225 and pushes the guide rod 225 to the right. The guide rod 225 drives the entire cleaning block 22 to move to the right. The cleaning strip 226 cleans the side of the backlight panel, and the return spring 221 is compressed.

[0047] Guide rod 225 drives wedge block 223 to move inward under the action of inclined groove 212. The cleaning plate on the upper side of wedge block 223 cleans the lower edge of the backlight panel, achieving a thorough cleaning. Then, the inclined surface on the lower side of wedge block 223 contacts the LCD panel, wedge block 223 retracts, and the LCD panel and backlight panel are attached. Then, electric slider 12 drives rail 121 to move to the left, squeezing out the air bubbles between the LCD panel and the backlight panel. The worker installs the metal frame on the left and right sides of the LCD panel and the backlight panel. After the two are completely fixed, electric slider 12 returns to the right side. Then, the worker pulls telescopic buckle 151 to the right, the fixing buckle 213 is released, the clamping frame 21 rotates counterclockwise under the action of torsion spring, and then the pneumatic suction cup 19 releases pressure. The worker removes the LCD panel and backlight panel that have been fixed together by the metal frame for subsequent operations such as gluing.

[0048] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered within the protection scope of the present invention.
