Technical Field

[0001] This invention relates to the field of liquid crystal display module processing technology, specifically to a manufacturing process and apparatus for a thin and light liquid crystal display module. Background Technology

[0002] A typical liquid crystal display module generally consists of an upper LCD and a lower backlight, including an upper polarizer 1, an upper glass substrate 2, an upper ITO electrode 3, an upper PI film layer 4, a frame adhesive 5, liquid crystal 6, a spacer 7, an upper PI film layer 8, an upper ITO electrode 9, a lower glass substrate 10, a lower polarizer 11, a diffuser film 12, a light guide plate 13, and a reflective film 14, such as... Figure 1 As shown, 1 to 11 constitute the LCD, and 12 to 14 constitute the backlight. The working principle of a conventional liquid crystal display module is that light enters from the side of the backlight light guide plate 13, is reflected by the reflective film 14, is uniformly distributed by the dotted light guide plate 13, and then exits through the diffuser film 12 and enters the upper LCD, providing a uniform light source for the LCD. Due to the presence of the diffuser film 12, light guide plate 13, and reflective film 14, the thickness of the existing conventional liquid crystal display module is relatively thick.

[0017] S11: Attach the polarizer and the lower polarizer, and the production of a thin and light liquid crystal display module is now complete.

[0018] A fabrication apparatus for a thin and light liquid crystal display module includes a support strip, the interior of which is hollow. Two liquid inlet pipes are symmetrically fixed and connected to the outer surfaces of the support strip, each with a one-way valve at its port. An alignment groove is formed through the top outer surface of the support strip. The apparatus also includes:

[0019] An injection assembly is fixedly installed inside a support bar and deforms under compression.

[0020] An auxiliary component, which is fixedly installed on the outside of the support bar;

[0021] The infusion assembly includes a sponge strip, which is fixedly installed inside the support strip. The sponge strip is rectangular and has an installation groove inside. An elastic tube is fixedly connected to the inner surface of the installation groove. An outlet hole is opened through the outer surface of the elastic tube. The central axis of the elastic tube is consistent with the central axis of the inlet tube.

[0022] Preferably, the elastic tube is provided with a positioning tube inside, and the two ends of the positioning tube are fixedly connected to the inner surfaces of the two sides of the bearing strip. The two ends of the positioning tube are connected to the liquid inlet tube, wherein the positioning tube and the elastic tube are set to the same central axis.

[0023] Preferably, support bars are symmetrically fixedly connected to the outer surfaces of both sides of the positioning tube, and the end of the support bar away from the positioning tube is fixedly connected to the inner surfaces of both sides of the elastic tube. A through groove is opened through the outer surface of the positioning tube, and three through grooves are opened at fixed intervals around the central axis of the positioning tube.

[0024] Preferably, the outer surface of the positioning tube is elastically hinged with a reset strip, and the end of the reset strip away from the positioning tube is elastically hinged to the inner surface of the elastic tube. Four reset strips are arranged around the outer surface of the positioning tube, and the reset strips are arranged in pairs as a group. The two groups of reset strips are symmetrically arranged on both sides of the support strip.

[0025] Preferably, mounting strips are symmetrically arranged on both sides of the sponge strip, and the mounting strips are symmetrically fixedly connected to the inner surfaces of both sides of the bearing strip. Elastic telescopic plates are symmetrically fixedly connected to the two surfaces of the mounting strip near the sponge strip.

[0026] Preferably, the output end of the top elastic telescopic plate is fixedly connected to a top plate, and the output end of the bottom elastic telescopic plate is fixedly connected to a bottom plate. The top plate is fixedly connected to the top inner surface of the support strip, and the bottom plate is fixedly connected to the bottom inner surface of the support strip. The upper and lower surfaces of the sponge strip are respectively fixedly connected to the inner surfaces of the top plate and the bottom plate.

[0027] Preferably, the upper surface of the top plate is provided with an injection groove, which is aligned with the alignment groove. The injection groove is smaller than the alignment groove. A rubber ring is fixedly connected to the upper surface of the top plate and is disposed in the alignment groove. A traction rod is symmetrically rotatably connected to the top inner surface of the bearing bar. Pull ropes are symmetrically fixedly connected to the upper surfaces of both sides of the top plate.

[0028] Preferably, the auxiliary component includes a mounting plate, which is symmetrically fixedly connected to the upper surfaces of both sides of the support strip. A cleaning plate is elastically slidably inserted through the mounting plate. The two cleaning plates are initially combined into a near-triangular shape. A scraper is slidably attached to the inner surface of the cleaning plate. The scraper is symmetrically fixedly connected to the upper surface of the support strip and is located outside the alignment groove. Sealing plates are slidably attached to the two sides of the cleaning plate. The sealing plates are symmetrically fixedly connected to the upper surfaces of both sides of the support strip. The entire device is placed in a vacuum environment, and liquid crystal is injected into the support strip through the liquid inlet pipe. Then, the sealing end of the liquid crystal empty cell is aligned with the alignment groove on the support strip and the liquid crystal empty cell is moved downward until it moves into the alignment groove. The pressure is continued, and the liquid crystal inside the elastic tube enters the sponge strip through the liquid outlet under the pressure of the liquid crystal empty cell. It then continues to enter the liquid crystal empty cell through the sponge strip. When the liquid crystal empty cell is filled with a sufficient amount of liquid crystal, the liquid crystal empty cell is moved upward to complete the liquid crystal injection.

[0029] 3. Beneficial effects

[0030] This invention provides a manufacturing process and apparatus for a thin and light liquid crystal display module. It has the following beneficial effects:

[0031] (I) The manufacturing process of this thin and light LCD module involves light entering from the bottom, passing through the lower polarizer, and then passing through the light-diffusing dots printed on the bottom of the lower glass substrate to homogenize the incoming light before it enters the upper LCD. This has significant advantages: eliminating the diffuser, light guide plate, and reflective film greatly reduces the thickness of the LCD module and also reduces the cost of the product. Because the diffuser, light guide plate, and reflective film are removed, light loss is also reduced, which improves the utilization rate of the light source and can further reduce the power consumption of the whole machine.

[0032] (II) The manufacturing apparatus for this thin and light liquid crystal display module avoids the common practice in the prior art of aligning the liquid crystal cell with the sponge strip and then filling the vacuum equipment with inert gas to allow the liquid crystal to enter the liquid crystal cell by pressure change. This not only wastes a large amount of inert gas, but also contaminates the liquid crystal and causes quality problems. When the liquid crystal cell squeezes the sponge strip, causing the elastic tube to deform, it also squeezes the reset strip, causing the two ends of the reset strip to deflect. After the liquid crystal cell is removed, the reset strip resets under the action of torque, which in turn causes the elastic tube to reset. This effectively ensures the amount of liquid crystal carried by the cavity inside the elastic tube, ensuring that the liquid crystal can be supplied sufficiently during repeated continuous production, greatly improving the stability of liquid crystal filling, and reducing the hidden danger of quality problems caused by insufficient liquid crystal filling in the liquid crystal cell.

[0033] (III) The manufacturing apparatus for this thin and light LCD display module: After the LCD empty cell enters the alignment groove, it directly contacts the rubber ring. The rubber ring seals the internal cavity of the LCD empty cell and the cavity in the support strip, making them a whole. This prevents the LCD from leaking through the gap between the alignment groove and the LCD empty cell during liquid crystal filling. As the LCD empty cell continues to move downward, the rubber ring applies pressure to the top plate, causing the top plate to move downward under pressure. This generates a downward pulling force on the pull rope, causing the bottom plate at the other end of the pull rope to move upward under the pulling force. Thus, during liquid crystal filling, the mutual movement of the top and bottom plates squeezes the sponge strip, thereby causing the elastic tube to be squeezed by the bidirectional pressure of the top and bottom plates. This diverts the squeezing force, preventing the upper side of the elastic tube from being in a state of compression deformation for a long time due to unidirectional squeezing of the LCD empty cell, which reduces its service life. At the same time, the bidirectional squeezing method can also significantly improve the liquid crystal filling efficiency and increase production capacity.

[0034] (iv) The fabrication apparatus for this thin and light liquid crystal display module, after liquid crystal injection is completed, the top plate and bottom plate are reset under the elastic force of the elastic telescopic plate, which facilitates the next liquid crystal injection and greatly improves the automation level of the apparatus. When the empty liquid crystal cell moves towards the alignment slot, it will first contact the top of the cleaning plate. Under the action of the squeezing force, the cleaning plates on both sides slide down the mounting plate to the side, opening the alignment slot. After liquid crystal injection is completed, as the empty liquid crystal cell moves upward, the cleaning plate will slide on the side surface of the empty liquid crystal cell until the top of the cleaning plate contacts the bottom surface of the empty liquid crystal cell. As the empty liquid crystal cell continues to move upward, the reset of the cleaning plate allows the cleaning plate to pass through the cleaning plate. The cleaning plate exerts a scraping force on the bottom surface of the empty LCD cell, thereby automatically cleaning the bottom surface of the empty LCD cell after liquid crystal filling. This achieves integrated liquid crystal filling and cleaning operations, significantly improving production efficiency. At the same time, the cleaned liquid crystal is guided by the scraper to flow back to the upper surface of the sponge strip and is reabsorbed, facilitating the next filling and greatly improving the utilization efficiency of the liquid crystal and reducing waste. In addition, the cleaning plate can also seal the alignment groove, protecting the upper surface of the sponge strip when not in production, and preventing impurities from falling onto the upper surface of the sponge strip and entering the empty LCD cell during filling, thus avoiding quality problems.

[0083] The working principle of this liquid crystal display module is as follows: light enters from the bottom, passes through the lower polarizer 11, and then passes through the light-diffusing dots printed on the bottom of the lower glass substrate 10 to homogenize the incoming light before it enters the upper LCD. This has significant advantages. Removing the diffuser 12, light guide plate 13, and reflective film 14 greatly reduces the thickness of the liquid crystal display module and also reduces the cost of the product. Since the diffuser 12, light guide plate 13, and reflective film 14 are removed, light loss is also reduced, which improves the utilization rate of the light source and can further reduce the power consumption of the whole machine.

[0084] Fourth embodiment: as Figures 4 to 10 As shown, a manufacturing apparatus for a thin and light liquid crystal display module includes a support strip 15, the interior of which is hollow. Liquid inlet pipes 16 are symmetrically fixed and connected to the outer surfaces of both sides of the support strip 15. One-way valves are provided at the ports of the liquid inlet pipes 16. An alignment groove 17 is formed through the top outer surface of the support strip 15. The apparatus also includes:

[0085] Injection assembly 18 is fixedly installed inside the support bar 15, and the injection assembly 18 deforms under compression.

[0086] Auxiliary component 19 is fixedly installed on the outside of the support bar 15;

[0087] The infusion assembly 18 includes a sponge strip 181, which is fixedly installed inside the support strip 15. The sponge strip 181 is rectangular and has an installation groove 182 inside. An elastic tube 183 is fixedly connected to the inner surface of the installation groove 182. An outlet hole 184 is opened through the outer surface of the elastic tube 183. The central axis of the elastic tube 183 is consistent with the central axis of the inlet pipe 16.

[0088] The elastic tube 183 is provided with a positioning tube 185 inside. The two ends of the positioning tube 185 are fixedly connected to the inner surfaces of both sides of the support strip 15. The two ends of the positioning tube 185 are connected to the liquid inlet tube 16. The positioning tube 185 and the elastic tube 183 are set to the same central axis.

[0089] Support bars 186 are symmetrically fixedly connected to the outer surfaces of both sides of the positioning tube 185. The end of the support bar 186 away from the positioning tube 185 is fixedly connected to the inner surfaces of both sides of the elastic tube 183. A connecting groove 187 is opened through the outer surface of the positioning tube 185. Three connecting grooves 187 are opened at fixed intervals around the central axis of the positioning tube 185.

[0090] The outer surface of the positioning tube 185 is elastically hinged with a reset strip 188. The end of the reset strip 188 away from the positioning tube 185 is elastically hinged to the inner surface of the elastic tube 183. Four reset strips 188 are arranged around the outer surface of the positioning tube 185, and the reset strips 188 are arranged in pairs as a group. The two groups of reset strips 188 are symmetrically arranged on both sides of the support strip 186.

[0091] The two sides of the sponge strip 181 are symmetrically provided with mounting strips 189. The mounting strips 189 are symmetrically fixedly connected to the inner surfaces of the two sides of the bearing strip 15. The two sides of the mounting strip 189 near the sponge strip 181 are symmetrically fixedly connected with elastic telescopic plates 1810.

[0092] The top elastic telescopic plate 1810 is fixedly connected to the top plate 1811 at its output end, and the bottom elastic telescopic plate 1810 is fixedly connected to the bottom plate 1812 at its output end. The top plate 1811 is fixedly connected to the top inner surface of the support strip 15, and the bottom plate 1812 is fixedly connected to the bottom inner surface of the support strip 15. The upper and lower surfaces of the sponge strip 181 are fixedly connected to the inner surfaces of the top plate 1811 and the bottom plate 1812, respectively.

[0093] The upper surface of the top plate 1811 is provided with a grouting groove 1813, which is aligned with the alignment groove 17. The grouting groove 1813 is smaller than the alignment groove 17. A rubber ring 1814 is fixedly connected to the upper surface of the top plate 1811. The rubber ring 1814 is set in the alignment groove 17. A traction rod 1815 is symmetrically rotatably connected to the top inner surface of the bearing bar 15. Pull ropes 1816 are symmetrically fixedly connected to the upper surfaces of both sides of the top plate 1811. The end of the pull rope 1816 away from the top plate 1811 passes around the traction rod 1815 and is fixedly connected to the upper surfaces of both sides of the bottom plate 1812.

[0094] Fifth embodiment: as follows Figures 4 to 10 As shown, the auxiliary component 19 includes a mounting plate 191, which is symmetrically and fixedly connected to the upper surfaces of both sides of the support strip 15. A cleaning plate 192 is elastically and slidably inserted through the mounting plate 191. The two cleaning plates 192 are initially combined into a near-triangular shape. A scraper 193 is slidably attached to the inner surface of the cleaning plate 192. The scraper 193 is symmetrically and fixedly connected to the upper surface of the support strip 15 and is located on the outer side of the alignment groove 17. A sealing plate 194 is slidably attached to both sides of the cleaning plate 192. The sealing plate 194 is symmetrically and fixedly connected to the upper surfaces of both sides of the support strip 15.

[0095] During operation, the entire device is placed in a vacuum environment, and liquid crystal is injected into the carrier strip 15 through the liquid inlet pipe 16. Then, the sealed end of the liquid crystal cell is aligned with the alignment groove 17 on the carrier strip 15, and the liquid crystal cell is moved downwards until it enters the alignment groove 17. Continued downward pressure causes the liquid crystal inside the elastic tube 183 to enter the sponge strip 181 through the liquid outlet hole 184 under the pressure of the liquid crystal cell. The liquid crystal then continues to enter the liquid crystal cell through the sponge strip 181. Once sufficient liquid crystal is injected into the liquid crystal cell, the liquid crystal cell is moved upwards to complete the liquid crystal injection. However, in existing technologies, the liquid crystal cell is typically aligned with the sponge strip 181, and inert gas is injected into the vacuum equipment to utilize pressure changes to force the liquid crystal into the liquid crystal cell. This not only causes significant... The waste of inert gas also contaminates the liquid crystal, causing quality problems. When the empty liquid crystal cell squeezes the sponge strip 181, causing the elastic tube 183 to deform, it also squeezes the reset strip 188, causing the two ends of the reset strip 188 to deflect. After the empty liquid crystal cell is removed, the reset strip 188 resets under torque, which in turn causes the elastic tube 183 to reset. This effectively ensures the amount of liquid crystal carried by the cavity inside the elastic tube 183, ensuring a sufficient supply of liquid crystal during repeated continuous production, greatly improving the stability of liquid crystal filling, and reducing the risk of quality problems caused by insufficient liquid crystal injection in the empty liquid crystal cell. After the empty liquid crystal cell enters the alignment groove 17, it will directly contact the rubber ring 1814, and the rubber ring will... The sealing of the rubber ring 1814 connects the internal cavity of the liquid crystal cell with the cavity of the support strip 15, forming a unified whole. This prevents liquid crystal leakage through the gap between the alignment groove 17 and the liquid crystal cell during liquid crystal filling. As the liquid crystal cell continues to move downwards, the rubber ring 1814 applies pressure to the top plate 1811, causing it to move downwards. This pressure generates a downward pull on the pull rope 1816, causing the bottom plate 1812 at the other end of the pull rope 1816 to move upwards. Thus, during liquid crystal filling, the relative movement of the top plate 1811 and bottom plate 1812 compresses the sponge strip 181, thereby promoting the flow of liquid crystal through the top plate 1811 and bottom plate 1812. The bidirectional pressure of 812 squeezes the elastic tube 183, diverting the extrusion force and preventing the upper side of the elastic tube 183 from being in a state of prolonged compression deformation due to unidirectional extrusion of the liquid crystal cell, thus reducing its service life. Simultaneously, the bidirectional extrusion method can significantly improve the liquid crystal filling efficiency and increase production capacity. After liquid crystal filling is completed, the top plate 1811 and bottom plate 1812 reset under the elastic force of the elastic telescopic plate 1810, facilitating the next liquid crystal filling and greatly improving the automation level of the device. Furthermore, when the liquid crystal cell moves towards the alignment slot 17, it first contacts the top of the cleaning plate 192. Under the extrusion force, the cleaning plates 192 on both sides slide downwards and to the sides along the mounting plate 191, opening the alignment slot 17.After liquid crystal filling is completed, the cleaning plate 192 slides on the side surface of the empty liquid crystal cell as it moves upwards until its top contacts the bottom surface. As the empty cell continues to move upwards and the cleaning plate 192 resets, it generates a scraping force on the bottom surface of the empty cell. This achieves automatic cleaning of the bottom surface of the empty liquid crystal cell after filling, integrating liquid crystal filling and cleaning operations, significantly improving production efficiency. Simultaneously, the cleaned liquid crystal is guided by the scraper 193 back to the upper surface of the sponge strip 181 for reabsorption, facilitating the next filling and greatly improving liquid crystal utilization efficiency and reducing waste. Furthermore, the cleaning plate 192 can seal the alignment groove 17, protecting the upper surface of the sponge strip 181 during non-production periods and preventing impurities from falling onto it and entering the empty liquid crystal cell during filling, thus avoiding quality problems.
